SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This annual report contains forward-looking statements. These forward-looking statements include statements regarding our financial position; our expectations concerning future operations, margins, profitability, liquidity and capital resources; our business strategy and other plans and objectives for future operations; and all other statements that are not historical facts. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “thinks,” “estimates,” “seeks,” “predicts,” “potential,” and similar expressions. Although we believe that these statements are based on reasonable assumptions, they are subject to numerous factors, risks and uncertainties that could cause actual outcomes and results to be materially different from those projected. These factors, risks and uncertainties include those listed under “Risk Factors” and elsewhere in this annual report. Those factors, among others, could cause our actual results and performance to differ materially from the results and performance projected in, or implied by, the forward-looking statements. They include:

 

   

unpredictable volume and timing of customer orders, which are not fixed by contract but vary on a purchase order basis;

 

   

the loss of one or more key customers or the significant reduction, postponement, rescheduling or cancellation of orders from these customers;

 

   

general economic conditions or conditions in the semiconductor or consumer electronics market;

 

   

decreases in the overall average selling prices of our products;

 

   

changes in the relative sales mix of our products;

 

   

the payment, or non-payment, of cash dividends in the future at the discretion of our board of directors;

 

   

changes in our cost of finished goods;

 

   

the effects on our business and our customer’s business taking into account the ongoing US-China tariffs and trade disputes;

 

   

the effects, if any, on the price of our ADSs as a result of the announcement and implementation of our previously announced share repurchase program;

 

   

the availability, pricing and timeliness of delivery of other components and raw materials used in our and our customers’ products;

 

   

our customers’ financial health, sales outlook, purchasing patterns and inventory adjustments based on consumer demand, market adoption of new technologies and general economic conditions;

 

   

our ability to successfully develop, introduce and sell innovative, new or enhanced products in a timely manner; and

 

   

the timing of new product announcements or introductions by us or by our competitors.

One or more of these factors could materially and adversely affect our operating results and financial condition in future periods. We cannot assure you that we will attain any meaningful estimates or maintain profitability or that the assumptions on which they are based are reliable.

Except as required by law, we undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise after the date of this annual report. All forward-looking statements contained in this annual report are qualified by reference to this cautionary statement. As you read and consider this annual report, you should carefully understand that the forward-looking statements are not guarantees of performance or results.

See Note 2 to our audited consolidated financial statement included in this annual report for more information.

Risk Factors

Because our operating results for any period could be adversely affected by a number of factors, some of which are outside of our control, and may therefore fluctuate significantly, our annual and quarterly operating results are difficult to predict.

Our operating results have fluctuated in the past and could do so in the future. For example, our net income decreased $36.0 million from 2016 to 2017 and increased $23.1 million from 2017 to 2018. Fluctuations in our operating results may be due to a number of factors, including, but not limited to, those listed below and those identified throughout this “Risk Factors” section:

 

   

competitive pressures and other factors such as the qualification, availability and pricing of competing products and technologies and the resulting effects on sales and pricing of our products;

 

   

changes in demand for electronic devices into which our semiconductor solutions are directly or indirectly incorporated;

 

   

our customers’ sales outlook, purchasing patterns and inventory adjustments based on market demand, adoption of new technologies and general economic conditions;

 

2


Table of Contents
   

the loss of one or more key customers or the significant reduction, timing or cancellation of orders from these customers;

 

   

seasonality or cyclical fluctuations in our markets;

 

   

our ability to develop or acquire, introduce, market and transition to volume production new or enhanced products and technologies in a cost-effective and timely manner;

 

   

changes in supply and availability of flash memory components used in our and our customer’s products;

 

   

changes in our product mix or customer mix and their effect on our gross margin;

 

   

changes in foreign currency exchange rates;

 

   

the availability and pricing of third party semiconductor foundry services;

 

   

unpredictable volume and timing of customer orders, which are not fixed by contract but vary on an order-to-order basis;

 

   

deferrals or reductions of customer orders in anticipation of new products or product enhancements from us or our competitors or other providers of integrated circuits;

 

   

our ability to timely and accurately predict market requirements and evolving industry trends and to identify and capitalize upon opportunities in new markets; and

 

   

the overall cyclicality of, and changing economic and market conditions in, the semiconductor industry.

These and other factors make it difficult for us to assess our future performance. Our sales and operating results are difficult to predict and have in the past, and will likely in the future, fluctuate from period to period. We could fail to achieve the operating targets that we have announced, such as revenue growth, gross margin, and operating expense. In addition, our operating results in the future may be below the expectations of securities analysts or investors, which would likely cause the market price of our ADSs to decline. Any variations in our period-to-period performance may also cause the market price of our ADSs to fluctuate. Accordingly, you should not rely on the results of any prior periods as a reliable indicator of our future operating performance.

Our operating results and stock price may be adversely affected by worldwide economic uncertainties including political and social instability and industry-specific conditions in the markets we operate.

Disruptions or uncertainties in the economy, including any political and social instability may lead consumers and business to postpone spending. This in turn may cause our customers to cancel, decrease or delay their existing and future orders with us. Furthermore, we operate primarily in the semiconductor industry, which is cyclical in nature and subject to evolving industry standards. In the past, the semiconductor industry had experienced significant downturns characterized by decreases in product demand, excess customer inventories and accelerated erosion of prices. The semiconductor industry also periodically experiences increased demand and production capacity constraints, which may affect our ability to deliver products to our customers. Economic volatility can cause extreme difficulties for our customers and vendors in accurately forecasting and planning future business activities. The uncertain effects and resolution of the US-China tariff dispute is an example of political uncertainty. This unpredictability could cause our customers to reduce spending on our products and services, which would delay and lengthen sales cycles. The accurate forecasting and planning for our operations heavily rely on these worldwide economic and industry-specific conditions, and the volatility and uncertainties associated with these factors may adversely affect our results of operation in a material manner.

Table of Contents

Since we have limited visibility as to the sales volume by our customers of devices using our products, our ability to accurately forecast future demand for and sales of our products is limited.

The majority of our products are integrated into devices that are sold directly or indirectly into markets which are difficult for us and our customers to accurately forecast as computing and mobile devices demand is subject to significant seasonality, with higher net sales generally in the second half of each year, when our customers place orders to meet increased demand during year-end holiday seasons, and other fluctuations. Also, as a significant portion of our quarterly sales are from orders received and fulfilled in that quarter, our visibility as to expected orders from our customers in subsequent periods and for any extended period of time is limited. Additionally, we depend upon our customers’ procurement forecasts in order to forecast demand for our products, and our customers’ procurement forecast may be subject to change. Our failure to accurately forecast demand for our products may result in lost sales or excess inventory and associated reserves or write-downs for our operations. Any of the aforementioned factors could affect sales of our products and thereby harm our business, financial condition and operating results.

If demand for our products declines in the major end-markets that we serve, our sales, net revenue and earnings will decrease.

Demand for our products is affected by a number of factors, including the general demand for the products in the end-markets that we serve and price attractiveness of the devices incorporating our products that our customers and vendors offer to end-markets. A significant amount of our sales revenue is derived from customers who use our controllers in expandable and embedded solid state storage solutions used in computing and mobile devices. Any significant decrease in the demand for these devices in the end-market may decrease the demand for our semiconductor solutions and may result in a significant decrease in our revenues and earnings. Computing and mobile devices that use our components rapidly change as product capabilities are upgraded or new classes of products are introduced, and these changes may result in a significant reduction in demand for our products. We cannot give any assurance that there will not be any downturn in the future or that any future downturn will not affect our results of operations. Any significant decrease in demand for end-user applications of semiconductors will negatively affect our sales, net revenue and earnings.

We may pursue acquisitions, investments and dispositions, which could adversely affect our results of operations.

Our growth strategy includes the acquisition of, and investment in, businesses that offer complementary products, services and technologies, augment our market coverage, or enhance our technological capabilities. Our recent acquisitions include Shannon Systems in 2015 and Bigtera in 2017. Our recent investments include DeepVision and ProGrade in 2018. We may not be able to identify suitable acquisition or investment opportunities, or to consummate any such transactions. In addition, our original estimates and assumptions used in assessing any transaction may be inaccurate and we may not realize the expected financial or strategic benefits of any such transaction.

Any acquisitions we may undertake involve risks and uncertainties, such as unexpected delays, challenges and related expenses, and diversion of management’s attention. We may become subject to legal proceedings relating to the acquisition and the integration of acquired businesses may not be successful. The integration of an acquired business involves significant challenges, including, among others: potential disruption of our business, diversion of management’s attention from daily operations and the pursuit of other opportunities; incurring significant restructuring charges and amortization expense, assuming liabilities and ongoing lawsuits, potential impairment of acquired goodwill and other intangible assets, and increasing our expenses and working capital requirements; and implementing our management information systems, operating systems and internal controls for the acquired operations. In addition, our due diligence process may fail to identify significant issues with the acquired company’s products, financial disclosures, accounting practices, legal, tax and other contingencies and compliance with local laws and regulations. These difficulties may be complicated by factors such as the size of

the business or entity acquired, geographic and cultural differences, lack of experience operating in the industry or geographic markets of the acquired business, potential loss of key employees and customers, the potential for deficiencies in internal controls at the acquired or combined business, performance problems with the acquired business’ technology, exposure to unanticipated liabilities of the acquired business, insufficient revenue to offset increased expenses associated with the acquisition, adverse tax consequences and our potential inability to achieve the growth prospects or synergies expected from any such acquisition.

Failure to manage and successfully integrate the acquisitions we make, or to improve sales and margins of the acquired businesses, could materially harm our business, operating results and margins.

Any future acquisitions we make may require debt or equity financing, which, in the case of debt financing, would increase our leverage and interest expenses, and in the case of equity financing, would be dilutive to our existing stockholders. Acquisitions made in cash would reduce our cash reserves.

From time to time, we may also seek to divest or wind down portions of our business, either acquired or otherwise, or we may exit minority investments, each of which could materially affect our cash flows and results of operations. In March 2019, we announced that we had entered into an agreement to sell FCI to Dialog Semiconductor. Any future dispositions we may make could involve risks and uncertainties, including our ability to sell such businesses on terms acceptable to us, or at all. In addition, any such dispositions could result in disruption to other parts of our business, potential loss of employees or customers, or exposure to unanticipated liabilities or ongoing obligations to us following any such dispositions. For example, in connection with such dispositions, we may enter into transition services agreements or agree to provide certain indemnities to the purchaser, which may result in additional expenses and may adversely affect our financial condition and results of operations. See “Item 8. Recent Developments”.

We depend on a small number of customers for a significant portion of our revenues and a loss of some of these customers would result in the loss of a significant portion of our revenues.

We derived a substantial portion of our revenue from sales to a relatively small number of customers. As a result, the loss of any significant customer could materially and adversely affect our financial condition and results of operations. Sales to our five largest customers represented approximately 58%, 57% and 54% of our net revenue in 2016, 2017 and 2018, respectively. Sales to two customers in 2017 and 2018, and one customer in 2016 accounted for 10% or more of our net revenue, representing 28%, 39% and 34% of our net revenue in 2016, 2017 and 2018, respectively. In 2017 and 2018, the significant customers were SK Hynix and Intel and in 2016, SK Hynix. The identities of our largest customers and their respective contributions to our net revenue have varied and will likely continue to vary from period to period.

We expect that we will continue to depend on a relatively limited number of customers for a substantial portion of our net sales and our ability to maintain good relationships with these customers will be important to the ongoing success of our business. We cannot assure you that the revenue generated from these customers, individually or in the aggregate, will reach or exceed historical levels in any future period. Our failure to meet the demands of these customers could lead to a cancellation or reduction of business from these customers. In addition, loss, cancellation or reduction of business from, significant changes in scheduled deliveries to, or decreases in the prices of products sold to any of these customers could significantly reduce our revenues and adversely affect our financial condition and operating results. Moreover, any difficulty in collecting outstanding amounts due from our customers particularly customers who place large orders, would harm our financial performance. In addition, if our relationships with our largest customers are disrupted for any reason, it could have a significant impact on our business.

NAND industry cyclicality could adversely affect our growth and profitability.

The NAND industry is highly capital intensive and regularly experiences cycles of shortages and excess supply and related rapid increases and sharp decreases in NAND component prices. The price of solid state

Table of Contents

storage devices, such as SSDs and eMMC and UFS devices, in which NAND accounts for a significant portion of material cost, could also rise and fall with NAND component prices. Falling prices for solid state storage devices could trigger stronger market demand for these devices as well as controllers used in them, and conversely, rising prices for solid state storage devices could cause demand for these devices as well as controller used in them to fall, which could negatively affect our sales and profitability.

Additionally, during periods of NAND shortage, our sales and profitability could be negatively affected in many other ways, including: (i) our non-NAND vendor storage customers and we may not be able to procure sufficient supplies of NAND components for our Shannon data center SSDs and Ferri industrial SSDs, which could lead to reduced sales of our SSD solutions, and furthermore, to higher cost of procured NAND components and reduced SSD solutions profitability; (ii) NAND manufacturers may divert NAND supply away from module maker customers who are our controller customers towards their own internal consumption, which could lead to reduced procurement of our controllers; and (iii) NAND manufacturers may divert NAND supply away from products using our controllers towards products not using our controllers and our sales could be reduced.

During periods of NAND excess supply when NAND prices are falling sharply, our sales and profitability could also be negatively affected in additional ways, including: (i) NAND manufacturers facing reduced demand for NAND components and storage devices may temporarily build NAND inventory instead of selling at lower prices, and this may cause a reduction in controller demand; (ii) module maker customers that are exposed to volatile NAND pricing conditions may temporarily become more cautious in procuring NAND components, which could lead to reduced levels of controller procurement and storage device production; (iii) OEMs may temporarily limit procurement of storage devices in expectation of procuring more at a later date and at a lower price, which could restrain storage device and controller procurement; and (iv) NAND vendor and module maker customers that are under margin pressure because of falling NAND prices may seek price concessions from their controller suppliers.

If we fail to accurately anticipate and respond to market trends or fail to develop and introduce new or enhanced products to address these trends on a timely basis, our ability to attract and retain customers could be impaired and our competitive position could be harmed.

We operate in industries characterized by rapidly changing technologies and industry standards as well as technological obsolescence, and our products have short life cycles. NAND manufacturers introduce new generations of technology at regular cycles of every one to two years, and every generation of technology, such as high-layer count 3D NAND and multi-level cell, results in increasing lower cost NAND memory components with worse data retention and endurance characteristics that require management by more sophisticated controller solutions. Over the last decade, rapid reductions in NAND component cost have led to a growing proliferation of new applications, from smartphones to PCs and data centers, which use SSDs and other types of solid state storage devices that are dependent on controllers for delivering required storage performance, such as for PCI Express, in terms of data rate, latency and other features. We believe that our future success depends on our ability to develop and introduce new technologies and products for new applications to generate new sources of revenue to replace, or build upon, existing product revenue streams for applications that are mature or in secular decline. If we are not able to repeatedly introduce, in successive years, new products for new applications that ship in volume, our revenue will likely not grow and may decline significantly and rapidly.

In addition, we may not have sufficient management resources to manage, R&D capabilities to address, and financial resources to fund all of the required research to develop future innovations and meet changing industry standards. Moreover, even if we have adequate management resources, R&D capabilities, and financial resources, our future innovations may be outpaced by competing innovations. As a result, we may lose customers and significant sales, and our business and operating results may be materially and adversely affected.

The average selling prices of our controller ICs have historically decreased and will likely do so in the future, which could harm our revenue and profitability.

The controller ICs we develop and sell, especially those for expandable and embedded storage solutions, are used for high volume applications and have historically decreased over time, and we believe that it is possible they may also fall in the future. We may experience period-to-period fluctuations in future operating results if our average selling prices decline. We may be forced to reduce the average unit price of our products in response to new product introductions by our competitors, competitive pricing pressures and other factors. The mobile and computing devices markets are extremely cost sensitive, which may result in rapidly declining average selling prices of electronic devices and components, such as those made by us, used in devices and create downward pressure on our average selling prices and operating results. To maintain acceptable operating results, we will need to develop and introduce new products and product enhancements on a timely basis and continue to reduce our costs. If we are unable to offset any reductions in our average selling prices by increasing our sales volumes or reducing corresponding production costs or if we fail to develop and introduce new products and enhancements on a timely basis, our sales and operating results will be materially and adversely affected.

A failure to accurately forecast our future sales may adversely affect our results of operations and harm our business.

We have limited sales visibility as our customers typically do not provide us with firm, long-term purchase commitments. Additionally, our customers may also have limited sales visibility because of the rapidly changing nature of the global economy, NAND supply and demand dynamics and the markets in which devices using our products are sold. Substantially all of our sales are made on a purchase order basis, which permits our customers to cancel, change or delay their product purchase commitments with little or no notice to us and often without penalty to them, which limits our ability to accurately forecast sales and maintain adequate inventory levels, manufacturing capacity and operating infrastructure requirements.

To ensure the availability of our products for our customers, in some cases we cause our manufacturers to begin manufacturing our products based on forecasts provided by these customers in advance of receiving purchase orders. However, these forecasts do not represent binding purchase commitments, and we do not recognize revenue from these products until they are shipped to the customer. As a result, we incur inventory and manufacturing costs in advance of anticipated revenue. Because demand for our products may not materialize, manufacturing based on forecasts subjects us to risks of high inventory carrying costs and increased obsolescence and may increase our costs. If we overestimate customer demand for our products or if purchase orders are cancelled or shipments delayed, we may end up with excess inventory that we cannot sell, which could have a material and adverse effect on our financial results. Conversely, if we underestimate demand, we may not have sufficient product inventory and may lose market share and damage customer relationships, which could also harm our business.

Because many of our expenses are fixed in the short term or are incurred in advance of anticipated sales, we may not be able to decrease our expenses in a timely manner to offset any shortfall of sales, or expand our R&D and other operating infrastructure in a timely manner to capture anticipated business opportunities. If we expand our business operations and demand for our products does not increase as we may have projected, our operating results could be affected by our higher operating expense levels. Conversely, if we maintain or reduce our business operations and related expenses in accordance with our projections and demand for our products increases more than expected, our operating results could be affected by lost business opportunity, less competitive economies of scale, and damaged relationships with our customers.

The loss of any of our key personnel or the failure to attract or retain specialized technical and management personnel could impair our ability to grow our business.

We rely heavily on the services of our key employees, including Wallace C. Kou, our President and Chief Executive Officer. In addition, our engineers and other key technical personnel are a significant asset and are the

Table of Contents

source of our technological and product innovations. We believe our future success will depend upon our ability to retain these key employees and our ability to attract and retain other skilled managerial, engineering, technical and sales and marketing personnel. The competition for such personnel, particularly technical personnel, is intense in our industry. We may not be successful in attracting and retaining sufficient numbers of technical personnel to support our anticipated growth. These technical personnel are required to design and develop integrated circuits, including firmware, and to introduce product enhancements for use in future applications. Despite the incentives we provide, our current employees may not continue to work for us, and if additional personnel were required for our operations, we may not be able to obtain the services of additional personnel necessary for our growth. In addition, we do not maintain “key person” life insurance for any of our senior managers or other key employees. The loss of any of our key employees or our inability to attract or retain qualified personnel, including engineers, could delay the development and introduction of, and have an adverse effect on our ability to sell, our products as well as have an adverse effect on our overall growth. In addition, if any other members of our senior management or any of our other key personnel join a competitor or form a competing company, we may not be able to replace them easily and we may lose customers, business partners, key professionals and staff members. Substantially all of our senior executives and key personnel have entered into confidentiality and non-disclosure agreements. In the event of a dispute between any of our senior executives or key personnel and our operating companies in Taiwan, China or Korea, we cannot assure you the extent, if any, to which these provisions may be enforceable in Taiwan, China, or Korea due to the constantly evolving nature of the Taiwanese, Chinese, and Korean legal systems.

We may not be able to deliver our products on a timely basis if our relationships with our suppliers, our semiconductor foundries or our assembly and test subcontractors are disrupted or terminated.

We do not own or operate semiconductor fabrication facilities. Instead, we rely on third parties to manufacture our semiconductors. Two outside foundries, Taiwan Semiconductor Manufacturing Company (“TSMC”) and Semiconductor Manufacturing International Corporation (“SMIC”), with fabs in Taiwan, Singapore, and China currently manufacture the majority of our semiconductors. As a result, we face several significant risks, including higher wafer prices, availability of wafers and other raw materials, lack of manufacturing capacity, quality assurance, manufacturing yields and production costs, limited control over delivery schedules and product quality, increased exposure to potential misappropriation of our intellectual property, labor shortages or strikes and actions taken by third party contractors that breach our agreements.

The ability of each foundry to provide us with semiconductors is limited by its available capacity and access to wafers. We do not have long-term agreements with any of these foundries and we place orders on a purchase order basis. We place our orders based on our customers’ purchase orders and sales forecasts. However, the foundries can allocate capacity to the production of the products of their other customers and reduce deliveries to us on short notice or increase the price they charge us. It is possible that other foundry customers that are larger and better financed than we are, or have long-term agreements with these foundries, may induce these foundries to reallocate capacity to them. Any reallocation could impair our ability to secure manufacturing capacity that we need for our products. In addition, interruptions to the wafer manufacturing processes caused by a natural disaster or human error could result in partial or complete disruption in supply until manufacturing is re-started or we are able to shift manufacturing to another fabrication facility. It may not be possible to obtain sufficient capacity or comparable production costs at another foundry. Migrating our design methodology to a new third-party foundry could involve increased costs, resources and development time comparable to a new product development effort. Any reduction in the supply of semiconductors for our products could significantly delay our ability to ship our products and potentially have negative effects on our relationships with existing customers and our results of operations. In addition, if our subcontractors terminate their relationships with us, we would be required to qualify new subcontractors, which could take at least six months, resulting in unforeseen operating problems, and our operating results may be materially and adversely affected.

If the foundries that provide us with the products for our operations do not achieve satisfactory yield or quality, or if the assembly and testing services fail us in the quality of their output, then our revenue, operating results and customer relationships will be affected.

The manufacture of semiconductors is a highly complex process. Minor deviations in the manufacturing process can cause substantial decreases in yield. In some situations, such deviations may cause production to be suspended. The foundries that manufacture our semiconductors have from time to time experienced lower than anticipated manufacturing yields, including yields for our semiconductors, typically during the production of new products or architectures or during the installation and start-up and ramp-up of new process technologies or equipment. If the foundries that manufacture our semiconductors do not achieve planned yields, our product costs could increase and product availability would decrease.

After the wafer fabrication processes, our wafers are shipped to our assembly and testing subcontractors. We have a system to maximize consistent product quality, reliability and yield that involves our quality assurance team working closely with subcontractors in the various phases of the assembly and testing processes. Our supplier quality management includes procedures such as processes to pre-qualify our manufacturing suppliers and subcontractors. However, despite our efforts to strengthen supplier quality management, if our foundries fail to deliver fabricated silicon wafers of satisfactory quality in the volume and at the price we require, or if our assembly and testing subcontractors fail to efficiently and accurately assemble and test our products, we will be unable to meet our customers’ demand for our products or to sell those products at an acceptable profit margin, which would have a material and adverse effect on our sales and margins and damage our customer relationships.

Failure to protect our proprietary technologies or maintain the right to certain technologies may negatively affect our ability to compete.

We believe that the protection of our intellectual property rights is and will continue to be important to the success of our business. We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We also enter into confidentiality or license agreements with our employees, business partners and other third parties, and have implemented procedures to control access to and distribution of our documentation and other proprietary information. Despite these efforts, we cannot assure you that these measures will provide meaningful protection of our intellectual property rights. Further, these agreements do not prevent others from independently developing technologies that are equivalent to or superior to our technology. In addition, unauthorized parties may attempt to copy or otherwise obtain and use our proprietary technology. Monitoring unauthorized use of our technology is difficult and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries such as Taiwan, Korea, and China where the laws may not protect our proprietary rights as fully as do the laws of the United States. In addition, if the foundries that manufacture our semiconductors lose control of our intellectual property, it could be more difficult for us to take remedial measures because our foundries are located in countries that do not have the same protection for intellectual property that is provided in the United States. Also, some of our contracts, including license agreements, are subject to termination upon certain types of change-of-control transactions.

As of March 31, 2019, we have 1,456 patents and 1,281 pending applications worldwide. We cannot be certain that patents will be issued as a result of our pending applications nor can we be certain that any issued patents would protect or benefit us or give us adequate protection from competing products. For example, issued patents may be circumvented or challenged and declared invalid or unenforceable or provide only limited protection for our technologies. We also cannot be certain that others will not design around our patented technology, independently develop our unpatented proprietary technology or develop effective competing technologies on their own.

Failure to successfully defend against intellectual property lawsuits brought against us may adversely affect our business.

Companies in and related to the semiconductor industry often aggressively protect and pursue their intellectual property rights. From time to time, we have received, and may continue to receive, notices that claim we have infringed upon, misappropriated or misused other parties’ proprietary rights. Moreover, in the past we were in litigation with parties that claim that we infringed their patents or misappropriated or misused their trade secrets. In addition, we or our customers may be sued by other parties that claim that our products have infringed their patents or misappropriated or misused their trade secrets, or that may seek to invalidate one or more of our patents. An adverse determination in any of these types of disputes could prevent us from manufacturing or selling some of our products, increase our costs of revenue and expose us to significant liability. Any of these claims may materially and adversely affect our business, financial condition and results of operations. For example, in a patent or trade secret action, a court could issue a preliminary or permanent injunction that would require us or our customer(s) to withdraw or recall certain products from the market or redesign certain products offered for sales or under development. We may also be liable for damages for past infringement and royalties for future use of certain technologies. See “Legal Proceedings” below.

In addition, any litigation to defend ourselves against claims that we have infringed the intellectual property rights of others, could, regardless of the ultimate outcome, materially and adversely affect our operating results by requiring us to incur significant legal expenses and diverting the resources of the company and the attention of our management team.

Because the markets in which we compete are highly competitive and many of our competitors have greater resources than we have, we cannot be certain that our products will compete favorably in the marketplace.

We face competition from a number of competitors, including Marvell and our flash memory customers. We expect to face competition in the future from our current and potential competitors. In addition, some of our flash memory customers have developed products and technologies that could replace their need for our products or otherwise reduce their demand for our products.

Some of our current and potential competitors have longer operating histories, greater name recognition, access to larger customer bases and significantly greater financial, sales and marketing, manufacturing, distribution, technical and other resources than we have. As a result, they may be able to respond more quickly to changing customer demands or to devote greater resources to the development, promotion and sales of their products than we can. Our current and potential competitors may develop and introduce new products that will be priced lower, provide superior performance or achieve greater market acceptance than our products. For our SSD solutions, if we are unable to procure sufficient supplies of flash memory, our customers may seek to purchase SSD solutions from other suppliers.

Our products must meet exacting specifications and undetected defects and failures may occur, which may cause customers to return or stop buying our products and may expose us to product liability risk and risks of indemnification against defects in our products.

Our products are complex and may contain undetected hardware or software defects or failures, especially when first introduced or when new versions are released. These errors could cause us to incur significant re-engineering costs, divert the attention of our engineering personnel from product development efforts and materially affect our customer relations and business reputation. If we deliver products with errors or defects, our credibility and the market acceptance and sales of our products could be harmed. Defects could also lead to liability for defective products as a result of lawsuits against us or against our customers. We have agreed to indemnify some of our customers in some circumstances against liability from defects in our products. A successful warranty or product liability claim could require us to make significant payments.

Our intellectual property indemnification practices may adversely impact our business.

We may be required to indemnify our customers and our third-party intellectual property providers for certain costs and damages of intellectual property infringement in circumstances where our products are a factor in creating infringement exposure. In the contracts under which we sell semiconductor products, we may have agreed to indemnify our customers against losses arising out of claims of unauthorized use of intellectual property. In some of our licensing agreements, we have agreed to indemnify the licensee against losses arising out of or related to our conduct or services. We cannot assure you that claims for indemnification will not be made or that these claims would not have a material and adverse effect on our business, operating results or financial condition.

We are exposed to potential impairment charges on goodwill and acquired intangible assets relating to acquisitions and on investments.

We had approximately US$58.3 million of goodwill and US$1.0 million of acquired intangible assets on our balance sheet as of December 31, 2018. We are required to perform testing for impairment losses annually or whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. If the fair value of the assets declines to below our carrying value, we could incur significant goodwill and intangible assets impairment charges, which could negatively impact our financial results. In November 2017, we wrote down FCI goodwill by US$10.3 million. In November 2018, we wrote down Bigtera goodwill and intangible assets by US$0.6 million and US$3.4 million, respectively.

In addition, from time to time, we have made investments in private companies and had approximately US$4.2 million of investments as of December 31, 2018. If the companies that we invested in are unable to execute their plans and succeed in their respective markets, we may not benefit from such investments, and we could potentially lose the amounts we invested. We evaluate our investment portfolio on a regular basis to determine if impairments have occurred. If the operations of any businesses that we have invested decline significantly, we could incur impairment charges that could have a material impact on our results of operations. In 2017, we recognized total impairment charges of US$120 thousand for our Cashido and Vastview investments.

In April 2019, we reduced our Shannon sales forecast meaningfully, which is a triggering event that will require us to reevaluate our Shannon reporting unit’s goodwill and intangible assets in the second quarter of 2019. See “Item 8. Recent Developments — Shannon Impairment Risk”.

Any failure to achieve and maintain effective internal controls could have a material adverse effect on our business, results of operations and the market price of our ADSs.

We are subject to reporting obligations under securities laws of the United States. The Securities and Exchange Commission, or the SEC, as required by Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, adopted rules requiring every public company to include in its annual report management’s assessment of the effectiveness of the company’s internal controls over financial reporting. In addition, an independent registered public accounting firm must attest to and report on the effectiveness of the company’s internal controls over financial reporting.

Our management and independent registered public accounting firm have concluded that our internal controls as of December 31, 2018 are effective. However, we cannot assure you that in the future we or our independent registered public accounting firm will not identify material weakness during the audit process or for other reasons. In addition, because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. As a result, if we fail to maintain effective internal controls over financial reporting or should we be unable to prevent or detect material misstatements due to error or fraud on a timely basis, investors could lose confidence in the reliability of our financial statements, which in turn could harm our business and results of operations, negatively impact the market price of our ADSs and harm our reputation.

We are subject to cybersecurity risk.

We experience cyberattacks of varying degrees on our technology infrastructure and systems and, as a result, unauthorized parties have obtained in the past, and may in the future obtain, access to our computer systems and networks. The technology infrastructure and systems of our suppliers, vendors and partners may also experience such attacks. Cyberattacks are external and internal threats that include, but are not limited to, malware, phishing, advanced persistent threats, denial of service attacks, malicious software downloads, insider security breaches, and hardware and software vulnerabilities. We believe cyberattack attempts are increasing in number and that cyberattackers are developing increasingly sophisticated systems and means to not only attack systems, but also to evade detection or to obscure their activities.

We have controls and policies in place, will continue to enhance our capabilities and upgrade our protective solutions to guard against known and emerging threats, detect malicious or unauthorized activities, and have recovery systems to minimize business disruptions. If efforts to breach our infrastructure and systems are successful or we are unable to protect against these risks, we could suffer interruptions, delays, or cessation of operations of our systems, and loss or misuse of proprietary or confidential information, intellectual property, or sensitive or personal information. Breaches of our infrastructure and systems could also cause our customers and other affected third parties to suffer loss or misuse of proprietary or confidential information, intellectual property, or sensitive or personal information, and could harm our relationships with customers and other third parties. As a result, we could experience additional costs, indemnification claims, litigation, and damage to our brand and reputation. All of these consequences could harm our reputation and our business and materially and adversely affect our operating results and financial condition.

Laws and regulations to which we are subject, as well as customer requirements in the area of environmental protection and social responsibility, could impose substantial costs on us and may adversely affect our business.

We are subject to various state, federal and international laws and regulations governing the environment, including restricting the presence of certain substances in electronic products. In addition, we are also subject to various industry requirements restricting the presence of certain substances in electronic products. Although our management systems are designed to maintain compliance, we cannot assure you that we have been or will be at all times in complete compliance with such laws and regulations. If we violate or fail to comply with any of them, a range of consequences could result, including fines, import/export restrictions, sales limitations, criminal and civil liabilities or other sanctions.

Recently there has been increased focus on environmental protection and social responsibility initiatives, which are subject to change, can be unpredictable, and may be difficult for us to comply with, given the complexity of our supply chain and our significant outsourced manufacturing. We are required to implement various standards or processes due to the adoption of rules or regulations that result from these initiatives, such as the SEC rules on the disclosure of the use of “conflict minerals.” If we are unable to comply, or ensure that our suppliers or contract manufacturers comply, with such standards or processes, customers may stop purchasing from us, which could adversely affect our sales and results of operations.

Our stock price has been, and may continue to be, volatile, which could result in investors losing all or part of their investments.

Since we completed our initial public offering in June 2005, the market price of our ADSs has been and likely will continue to be highly volatile and could be subject to wide fluctuations in response to numerous factors, including the following:

 

   

actual or anticipated variations in our quarterly operating results or those of our competitors, customers, or NAND flash vendors;

 

   

actual or anticipated changes in NAND flash supply and demand dynamics;

 

12


Table of Contents
   

actual or anticipated changes in our market share or the market share of our competitors;

 

   

the commencement or results of litigation;

 

   

announcements by us, our competitors, our customers, or their other suppliers of new products or technological innovations;

 

   

changes in financial estimates or recommendations by securities analysts;

 

   

the payment or non-payment of cash dividends at the discretion of our board of directors;

 

   

the announcement and implementation of share repurchase programs;

 

   

announcements by us or our competitors of significant acquisitions, divestitures or partnerships; and

 

   

actual or anticipated changes in the global economic or industry outlook.

Many of these factors are beyond our control and may negatively impact the market price of our ADSs, regardless of our performance. In addition, the stock market in general, and the market for technology and semiconductor companies in particular, have been highly volatile. Our ADSs may not trade at the same price levels as that of other semiconductor and technology companies, and shares of semiconductor and technology companies, in general, may not sustain their current market prices. These fluctuations as well as general economic, political, and market conditions may have an adverse effect on the market price of our ADSs.

There can be no assurance that we will continue to declare cash dividends on a quarterly basis, if at all or in any particular amounts.

Our Board of Directors declared payment of our first quarterly dividend on our common stock in January 2013 and the first dividend payment was made on March 4, 2013. Our Board of Directors has subsequently declared and paid dividends in each successive quarter. Beginning November 2, 2015 our Board of Directors, instead of declaring a quarterly dividend, declared an annual dividend payable in four quarterly installments. The continuation of declaring dividends or if at all, depends on, among other things, that the dividend payment is in the best interests of our shareholders, business visibility our results of operations, capital availability and future capital requirements, financial condition, statutory requirements, and other factors that the board of directors may deem relevant. The decision of any declaration of dividend payment, the amount and the frequency of such, if at all, is the discretion of our Board of Directors. Our dividend payments may change from time to time, and we cannot provide assurance that we will continue to declare dividends, if at all or in any particular amounts. A reduction in or elimination of our dividend payments could have a negative effect on our share price.

If we are characterized as a passive foreign investment company, U.S. Holders may experience adverse tax consequences.

Based on the present and projected composition of our income and valuation of our assets, we believe we are not currently classified as a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes. We will generally be classified as a PFIC for any taxable year in which either (a) at least 75% of our gross income is passive income or (b) at least 50% of the value (determined on the basis of a quarterly average) of our assets is attributable to assets that produce or are held for the production of passive income. If we are characterized as a PFIC, U.S. Holders may experience adverse tax consequences. See “ITEM 10. ADDITIONAL INFORMATION — Taxation — United States Federal Income Taxation.”

We are subject to risks associated with international operations which may harm our business.

We conduct our business worldwide. We are a Cayman Islands corporation with principal executive offices in Hong Kong and have most of our operations outside of the United States. We undertake our design and development activities primarily in China, Korea and Taiwan. Our integrated circuits are manufactured,

assembled, tested and packaged by third-parties located primarily in China, Korea, and Taiwan. We generated 89%, 92% and 90% of our revenue in 2016, 2017 and 2018, respectively, from sales to customers outside the United States, and for the year ended December 31, 2018, 66% of our revenue was from sales in three jurisdictions — Taiwan, Korea and China. International operations are subject to many other inherent risks, including but not limited to:

 

   

international economic and political conditions, such as political tensions between countries in which we do business (please also refer to Risk Factors relating to China, Korea, and Taiwan);

 

   

unexpected changes in, or impositions of, legislative or regulatory requirements;

 

   

complying with a variety of foreign laws;

 

   

differing legal standards with respect to protection of intellectual property and employment practices;

 

   

cultural differences in the conduct of business;

 

   

inadequate local infrastructure that could result in business disruptions;

 

   

exporting or importing issues related to export or import restrictions, tariffs, quotas and other trade barriers and restrictions, recently increased as a result of the ongoing trade disputes and tariffs between China and the U.S.;

 

   

financial risks such as longer payment cycles and difficulty in collecting accounts receivable;

 

   

adverse taxes rules, regulations and penalties; and

 

   

other factors beyond our control such as nature disasters, terrorism, civil unrest, war and diseases such as severe acute respiratory syndrome, the Avian influenza, and the Swine influenza.

Although our reporting currency is the U.S. dollar, and the majority of our sales and cost of sales are denominated in the U.S. dollar, the majority of our operating expenses are denominated in the NT dollar, and to a lesser extent Korean won, Chinese yuan and U.S. dollar. The functional currencies of our Korean operations and our Chinese operations are the Korean Won and the Chinese yuan, respectively. As a result, appreciation or depreciation of other currencies in relation to the U.S. dollar could result in material transaction and translation gains or losses that could adversely affect, or cause fluctuations in, our results of operations. We do not currently engage in currency hedging activities.

We operate primarily in regions that are susceptible to natural disasters.

Parts of the world, including Taiwan, Japan, China and the United States are susceptible to earthquakes. In 1999, 2008, and 2011, Taiwan, China, and Japan respectively, experienced severe earthquakes that caused significant property damage and loss of life. Although the 1999, 2008 and 2011 earthquakes did not have a material impact on our business, and the region has not suffered such a major earthquake in many years, the occurrence of such an event is unpredictable, and a major earthquake and consequent disruptive events could severely disrupt the normal operations of our business and have a material and adverse effect on our financial condition and operating results.

We face substantial political risks associated with doing business in Taiwan because of the tense political relationship between Taiwan and the People’s Republic of China.

A majority of our employees and a significant portion of our research and development and operations are based in Taiwan. In addition, most of our foundries and assembly and testing suppliers such as TSMC, SMIC, Advanced Semiconductor Engineering Group (“ASE”), Siliconware Precision Industries Co., Ltd. (“SPIL”), and King Yuan Electronics Corp. (“KYEC”) are located in either Taiwan or China. Accordingly, our business and results of operations and the market price of our ADSs may be affected by changes in Taiwan or China governmental policies, taxation, inflation or interest rates and by social instability and diplomatic and social

developments in or affecting Taiwan that are outside of our control. Taiwan has a unique international political status. China does not recognize the sovereignty of Taiwan. Although there have been significant economic and cultural ties between Taiwan and China in recent years, the political relations have often been strained. The government of China has indicated that it may use military force to gain control over Taiwan, particularly under what it considers as highly provocative circumstances, such as a declaration of independence by Taiwan or the refusal by Taiwan to accept China’s “One China” policy. On March 14, 2005, the National People’s Congress of China passed what is widely referred to as the “anti-secession” law, a law authorizing the Chinese military to attack Taiwan in order to block moves by Taiwan toward formalizing independence.

Past and recent developments in relations between Taiwan and China have on occasion depressed the market prices of the securities of Taiwanese companies or companies with significant business activities in Taiwan. We cannot assure you any contentious situations between Taiwan and China will always resolve in maintaining the current status quo or remain peaceful. Relations between Taiwan and China and other factors affecting military, political or economic conditions in Taiwan could have a material adverse effect on our financial condition and results of operations, as well as the market price and the liquidity of our ADSs.

We face substantial political risk associated from doing business in South Korea because of tensions in the political relationship between South Korea and North Korea.

Relations between South Korea and North Korea have been tense over most of South Korea’s history. In recent years, there have been heightened security concerns stemming from North Korea’s nuclear weapons and ballistic missile capabilities and uncertainty regarding North Korea’s actions and possible responses from the international community. More recent concerns over North Korea’s nuclear and ballistic missile testing programs, hostile and threatened actions by North Korea against South Korea, North Korea’s leadership succession, and relations between the United States and North Korea, have created a global security issue that may adversely affect South Korean business and economic conditions. South Korea was not a signatory of the armistice agreement that ended the Korean War, and since no peace treaty was signed between South Korea and North Korea, the two countries are technically still at war. We cannot assure you as to whether or when this situation will be resolved or change abruptly as a result of current or future events, including, without limitation, the effects, if any, of (i) recent increases to previously imposed United Nations and U.S. sanctions on North Korea, and (ii) the general increase in overtures and rhetoric by the North Korean government with respect to its nuclear capabilities and willingness to use such weapons as they see fit. Although talks have recently been held between South Korea and North Korea and between the U.S. and North Korea, political instability has generally continued with the current U.S. administration. We cannot give any assurance that the level of instability and tension in the Korean peninsula will not escalate in the future, or that the political regime in North Korea may not suddenly collapse. An adverse change in economic or political conditions in South Korea or North Korea or in South Korea’s relations with North Korea could have a material adverse effect on our South Korean subsidiaries and our company.

Our business depends on the support of the Taiwanese and South Korean governments, and a decrease in this support may increase our tax liabilities and decrease our net income.

Our Taiwan operating company has benefited from tax incentives provided by the Taiwanese government. For example, under the Statute for Upgrading Industries of Taiwan, we were granted tax credits by the Taiwan Ministry of Finance for qualifying research and development costs and in qualifying employee training expenses. In addition, Taiwan law offers preferential tax treatments to industries that are encouraged by the government. In 2010, “Statute for Industries Innovation” was passed to replace the “Statute for Upgrading Industries” in tax incentives. However, we are still eligible to use certain previously granted exemptions. See “Operating and Financial Review and Prospects — Principal Factors Affecting Our Results of Operations — Provision for income taxes” and Note 16 to our consolidated financial statements for a more detailed description of our ability to enjoy these preferential tax treatments. If any of our tax credits or our ability to take advantage of these preferential tax treatments are curtailed or eliminated, our net income may decrease materially. The last tax credit granted to us by the Taiwanese government expired at the end of 2016.

Table of Contents

The South Korean government provides a variety of tax incentives designed to promote designated industries such as the technology industry. We, like many Korean technology companies, have benefited from certain tax incentives, including tax credits for applicable research and development expenses and for investments made to improve business productivity. If these and other tax incentives are curtailed or eliminated, our net income may decrease materially. In March, 2019, we announced that we had entered into an agreement to sell our interest in FCI to Dialog Semiconductor. See “Item 8. Recent Developments”.

The enactment of legislation implementing changes in taxation of international business activities, the adoption of other tax reform policies or changes in tax legislation or policies could materially impact our financial position and results of operations.

Tax bills are introduced from time to time to reform taxation of international business activities. The Organisation for Economic Co-operation and Development, or OECD, has released guidance covering various topics, including country-by-country reporting, definitional changes to permanent establishment and guidelines in determining arm’s length transfer pricing. This guidance is collectively referred to as Base Erosion and Profit Shifting, or BEPS, an initiative that aims to standardize and modernize global tax policy. Depending on legislation ultimately enacted in connection with this guidance by jurisdictions in which we operate, there may be significant consequences for us due to our significant international business activities. For example, adoption of BEPS by foreign jurisdictions in which we operate could result in changes to tax policies, including transfer-pricing policies that could ultimately impact our tax liabilities to foreign jurisdictions. If any of these proposals are enacted into law, or if other international, consensus-based tax policies and principles are amended or implemented, they could have material adverse consequences on the amount of tax we pay and thereby on our financial position and results of operations. It is likely that new legislations enacted by the governments of the Cayman Islands and Macau could lead to higher operating and tax expenses for our business in the near future.

In addition, policies regarding corporate income taxes in numerous jurisdictions in which we operate are under heightened scrutiny. As a result, decisions by tax authorities regarding treatments and positions of corporate income taxes could be subject to legislative investigation and inquiry, which could result in changes in tax policies or prior tax rulings. As such, the taxes we previously paid may be subject to change and our taxes may increase in the future, which could have an adverse effect on our results of operations, financial condition and our corporate reputation.

We are subject to risks associated with development and construction of our Taiwan headquarters building.

In October 2018, we purchased 65,700 square feet of land in Hsinchu, Taiwan for a total cost of $58.9 million and expect to spend an estimated $75 million for the development and construction of our future Taiwan headquarters building, which is currently targeted for completion in 2024. We have no experience developing and constructing office buildings and managing real property of this scale. We may encounter unanticipated occurrences or conditions during construction that may increase the expense of the project. We may also encounter unanticipated delays in the construction of the new building and local government approvals for the project may be delayed. We are financing this construction from our cash balance, which could limit alternative deployments of capital. The purchase of the land and construction of the building will increase our fixed assets significantly and could reduce our return on invested capital. We are also exploring built-to-suit arrangements to reduce investments in fixed assets, but built-to-suit may not be obtainable at favorable terms; alternatively, once the office building has been constructed, we may consider a sale and leaseback if favorable terms can be obtained.

See “Item 8. Recent Developments — Sale of FCI”.

NAND Flash Controllers

NAND flash controllers are used to manage NAND flash, a type of non-volatile semiconductor memory manufactured by vendors such as Intel, Micron, Samsung, SK Hynix, Toshiba and Western Digital, used in solid state storage devices designed into smartphones, PCs and industrial, enterprise and data center applications. Solid state storage devices are widely used by OEMs and consumers in applications because of attractive characteristics that include high data storage capacity at low cost per bit, fast data read and write access time, low operating power requirements, small form-factor and shock resistance, which has led to applications using solid state storage devices proliferating and SSDs, a type of solid state storage device, displacing HDDs, a legacy type of storage device that uses electro-mechanical components.

All solid state storage devices using NAND flash require a controller, with most using a discrete controller IC and complementary firmware. Different types of controllers are used to develop different types of storage devices, for example an SSD controller is used specifically to develop an SSD and a UFS controller used to develop a UFS device, and controllers create different types of storage devices by providing the defining interface for the storage device type, delivering performance specified for the storage device type, managing NAND flash used in the storage device and implementing other necessary functionality.

There are many different types of solid state storage devices that use NAND flash, including SSDs used in PCs and other client devices, data centers and enterprise applications and eMMC and UFS used in smartphones and other smart devices. These different types of storage devices are developed using different types of specialized controllers, which enable the storage device to communicate with the host device according to the protocol defined for the specific interface. For example, PCIe NVMe SSDs require controllers that can interface according to the NVMe data transfer protocol for the PCIe data transfer system within a PC or server and UFS devices require controllers that can interface with the smartphone host device according to the UFS protocol. The storage device must deliver performance standards specified for the storage type according to the interface protocol and storage device performance is delivered by the controller utilized. Furthermore, controllers are often configured by OEMs to deliver optimized storage device operating performance relating to required metrics that include data transfer rates, IOPS (input/output operations per second), latency and stability.

In addition to providing the defining interface for a storage device and delivering specified performance requirements, the controller importantly must also manage NAND flash used in the storage device to: (i) ensure data reliability in NAND flash by detecting and correcting bit errors caused by read/write disturbance and adjacent cell interference; (ii) ensure data integrity in NAND flash by mapping bad blocks and preventing bad blocks from being used for storing data; (iii) maximize the life of NAND flash with wear-leveling algorithms which spread out the use of the memory array and equalize the use of all the memory cells; (iv) enhance the sequential and random read and write performance of NAND flash by utilizing multiple-plane architecture, interleaving, or other technologies; and (v) prevent data loss during sudden, unexpected host device power failures with advanced power cycling solutions. NAND flash from different vendors and from different generations of technology in terms of multi-level cell architecture (for example, 2-bits per cell, 3-bits per cell and 4-bits per cell) designed for 3D NAND flash at different layer stacking (for example, 64 layer, 72 layer, 92/96 layer) have different performance characteristics, which require different controller technology to provide suitable NAND flash management.

OEMs designing storage devices may require controller vendors to implement other functionalities such as: security for protecting software code, personal data and multimedia digital rights; end-to-end data path protection

to protect data inside a storage device, from the connection to the host system, through the circuits of the storage device, to the NAND flash; power-loss security features; Opal-compliant AES advanced full-disk encryption; and active operating temperature monitoring. Finally, controllers are designed to ensure that storage devices are compatible with a wide set of designated host devices and can be tuned to maximize compatibility and performance requirements.

We provide NAND flash controllers for many key applications, including: (i) high performance, cost effective client SSDs for PCs and other consumer-grade applications; (ii) enterprise-grade SSDs optimized for demanding data center and enterprise workload; (iii) embedded SSDs designed and tested for industrial, commercial and automotive applications; (iv) eMMC and UFS embedded memory for smartphones and other smart or IOT devices; and (v) memory cards and flash drives.

Sales and Marketing

We market and sell our products worldwide through a combination of direct sales personnel and independent electronics distributors. Our direct sales personnel are strategically located near our NAND flash manufacturer, leading technology OEM and modular maker customers in Taiwan, Korea, China, the United States, and Japan. Approximately 69% of our sales in 2016, 68% of our sales in 2017, and 68% of our sales in 2018 were attributable to our direct sales force while the remainder was attributable to distributors.

To supplement our direct sales, we have independent electronics distributors and sales reps located throughout the world. We selected these distributors and reps based on their ability to provide effective field sales, marketing communications and technical support for our products to our customers.

Our marketing group focuses on our product strategy, product development road maps, new product introduction process, demand assessment, competitive analysis, and product marketing. We seek to work with potential and existing customers early in their design process to best match our products to their needs, and more broadly, to ensure that product development activities, product launches, and on-going demand and supply planning occur in a well-managed, timely basis in coordination with our research and development, operations, and sales groups, as well as our customers and distributors. We also attend industry tradeshows and technical conferences to promote our products and solutions, maintain close contact with our existing customers to assess demand, and keep current with industry trends. Our participation in industry standards associations, such as JEDEC and the SD Association for our embedded storage and expandable storage products, helps us monitor the latest industry developments and promote our corporate profile. Our marketing group also works with our sales teams to identify new business opportunities.

We also have field application engineers (FAEs), who provide technical support and assistance to existing and potential customers in designing, testing and qualifying systems that incorporate our products. Our FAE organization is segmented by product and market to support our customers.

Research and Development

We devote a significant amount of resources to research and development for broadening and strengthening our portfolio of technology, products and solutions. Our engineering team has expertise in NAND flash management algorithms, system architecture, digital, mixed-signal and RF IC design, and software engineering. As of March 31, 2019, we have 1,456 patents and 1,281 pending applications worldwide. We will continue to actively pursue the filing of additional patent applications in important jurisdictions.

We believe technology research and product development is essential to our growth. Our primary research and development centers are located in Hsinchu and Taipei, Taiwan, Seoul, South Korea and Shanghai, China. Our facilities in Seoul focus primarily on our specialty RF IC products, our facilities in Hsinchu and Taipei focus primarily on our NAND flash controller products, and our facilities in Shanghai focus primarily on SSD solutions and specific product requirements of our customers in China.

Our research and development expenses were approximately US$92.4 million, US$102.1 million, and US$102.0 million for the years ended December 31, 2016, 2017 and 2018, respectively.

Manufacturing

We design and develop our products and electronically transfer our proprietary designs to independent foundries for the manufacturing and processing of silicon wafers. Once the wafers are manufactured, they are then shipped to third-party assembly and testing subcontractors. Individual dies on each wafer are assembled into finished chips and undergo several stages of testing before delivery to our customers. We also ship bare dies to our customers. We believe that our strategy of outsourcing wafer fabrication, packaging and testing enables us to

 

20


Table of Contents

benefit from the research and development efforts of leading manufacturers without the requirement to commit our own substantial capital investments. Our fabless business model also provides us with the flexibility to engage vendors who offer services that best complement our products and technologies.

Wafer fabrication. TSMC and SMIC are currently our primary foundries that manufacture most of our semiconductors. We use their fabs in Taiwan, Singapore, and China to fabricate our devices using mature and stable CMOS process technology, primarily with process node from 28 to 55 nanometers. We regularly evaluate the benefits and feasibility, on a product-by-product basis, of migrating to more cost efficient manufacturing process technologies.

Assembly and testing. Following wafer fabrication, our wafers are shipped to our assembly and test subcontractors where they are probed, singulated into individual dies, assembled into packaged chips, and undergo the process of electronic final testing. In order to minimize cost and maximize turn-around time, our products are designed to use low cost, industry standard packages and can be tested with widely available automatic testing equipment. We currently engage companies such as ASE, SPIL, and KYEC as our primary subcontractors for the assembly and testing of our products. We have dedicated teams of manufacturing engineers who maintain control over the process from the early stages of manufacturing. Our engineers work closely with our subcontractors to develop product testing and packaging programs to ensure these programs meet our product specifications, thereby maintaining our ownership of the functional and parametric performance of our semiconductors.

Quality and reliability assurance. We have designed and implemented a quality assurance system that provides the framework for continual improvement of products, processes and customer service. To ensure consistent product quality, reliability and yield, our quality assurance teams perform reliability engineering, quality control, international organization for standardization (ISO) system development, document control, subcontractor quality management and customer engineering services to closely monitor the overall process from IC design to after-sale customer support. In particular, we rely on in-depth simulation studies, testing and practical application testing to validate and verify our products. We emphasize a strong supplier quality management practice in which our manufacturing suppliers and subcontractors are pre-qualified by our quality assurance teams. Our suppliers are required to have a quality management system, certified to ISO 9000 standard. Our operations have been ISO 9001 certified since 1999.

Competition

We face competition from a number of competitors, including Marvell and our flash memory customers.

The markets for our products are intensely competitive, and are characterized by rapid technological change, evolving industry standards, frequent new product introductions and pricing pressures. Competition has intensified as a result of the increasing demand for higher levels of performance at competitive prices. We expect competition to intensify as current competitors continue to strengthen the depth and breadth of their product offerings. We believe that our ability to compete successfully in the rapidly evolving markets for our products depends on a number of factors, including, but not limited to:

 

   

the performance, features, quality and price of our products;

 

   

the timing and success of new product introductions by us, our customers and our competitors;

 

   

emergence, rate of adoption and acceptance of new industry standards;

 

   

our ability to obtain adequate foundry capacity at competitive prices; and

 

   

the number and nature of our competitors in a given market.

We expect increased competition in the future from emerging or established companies, customers or other third parties, any of which could acquire significant market share. See “Risk Factors” — Because the markets in

 

21


Table of Contents

which compete are highly competitive and many of our competitors have greater resources than we have, we cannot be certain that our products will compete favorably in the market place in Item 3 above.

Seasonality

See “Risk Factors — Because our operating results for any period could be adversely affected by a number of factors and therefore fluctuate significantly, our annual and quarterly operating results are difficult to predict” in Item 3 above and “Operating and Financial Review and Prospects — Principal Factors Affecting Our Results of Operations” in Item 5 below.

Intellectual Property

Our success and future revenue growth depends, in part, on our ability to protect our intellectual property. We rely on a portfolio of intellectual property rights, registered in the United States, Taiwan, and other countries, including patents, copyrights, trademark registrations, trade secret laws, contractual provisions, licenses, and other methods to protect our intellectual property.

As of March 31, 2019, we have 1,456 patents and 1,281 pending applications worldwide. There can be no assurance that patents will ever be issued with respect to these pending applications. Furthermore, it is possible that any patents held by us may be invalidated, circumvented, challenged or licensed to others. In addition, there can be no assurance that such patents will provide us with competitive advantages or adequately safeguard our proprietary rights. While we continue to file new patent applications with respect to our recent developments, existing patents are granted for prescribed time periods and will expire at various times in the future. We expect to continue to file patent applications where appropriate to protect our proprietary technologies.

Companies in the semiconductor industry have frequently demonstrated a readiness to commence litigation based on allegations of patent and other intellectual property infringement. From time to time, third parties may assert infringement claims against us. We may not prevail in any such litigation or may not be able to license patents from third parties on commercially reasonable terms, if at all. Litigation, regardless of the outcome, is likely to result in substantial cost and diversion of our resources, including our management’s time. Any such litigation could materially adversely affect us. In addition, in the contracts under which we sell semiconductor products, we may have agreed to indemnify our customers against losses arising out of claims of unauthorized use of intellectual property.

We intend to protect our intellectual property rights vigorously, but there can be no assurance that our efforts will be successful. In addition, the laws of other countries in which our products are sold may not protect our products and intellectual property rights to the same extent as the laws of the United States.

While our ability to effectively compete depends in large part on our ability to protect our intellectual property, we believe that our technical expertise, customer support capabilities, and ability to introduce new products in a timely and cost effective manner will be important factors in maintaining our competitive position.

We claim copyright and trademark protection for proprietary documentation for our products and a variety of branding marks. We have registered “Silicon Motion” and its logo (a three-dimensional cube depiction of the letters “SM”), FCI, the FCI logo, the Shannon Systems logo, “PCIe-RAID,” “DIRECT-IO,” “Hyper-IO,” “airRF,” “basicRF,” “ezRF,” “ezSYS,” “powerRF,” “twinRF,” “zipRF,” “zipSYS,” “VirtualZero,” “SSDLifeGuard,” “SSDLifeSaver,” “TurboMLC,” “FerriSSD,” “Ferri-eMMC,” “Bigtera,” the Bigtera logo, and “NANDXtend” as trademarks in the United States, Taiwan, and other countries.

We also attempt to protect our trade secrets and other proprietary information through agreements with our customers, suppliers, employees and consultants, and through other customary security measures.

We have entered into license agreements with third party intellectual property vendors for wafer fabrication tool libraries, semiconductor IP core, computer aided design tools, and software.

Facilities

As of the date of this annual report, we occupy facilities totaling approximately 419,500 square feet, which house our management and administration, operations, research and development and sales and marketing departments. Of our facilities, approximately 182,400 square feet are owned and approximately 237,100 square feet are occupied under leases. We consider our facilities insufficient to meet our future operational requirements and in 2018, purchased 65,700 square feet of land in Hsinchu, Taiwan for the construction of a future office building. See “Risk Factor” — We are subject to risks associated with the development and construction of our Taiwan headquarters building. The table below lists the location of our operating facilities.

that our business and financial performance are subject to substantial risks and uncertainties. Actual results could differ materially from those projected in the forward-looking statements. See “Special Note Regarding Forward-Looking Statements.” In evaluating our business, you should also carefully consider the information provided under the caption “Risk Factors” included in Item 3 of this annual report.

Overview

We are a global leader and pioneer in developing NAND flash controller ICs for solid-state storage devices. We sell more NAND flash controllers than any other company in the world and have one of the broadest portfolios of controller solutions and technologies. Our key products are controllers used in embedded storage products such as SSDs and eMMCs, as well as in expandable storage products such as memory cards and USB flash drives. Our products are widely used in computing and mobile devices and for industrial, enterprise, commercial and other applications. Our customers include most of the NAND flash makers, leading technology OEMs, and the majority of storage device module makers. More NAND flash products, especially next-generation flash, produced by Intel, Micron, Samsung, SK Hynix, Toshiba and Western Digital are supported by Silicon Motion controllers than any other company. We are the world’s leading merchant supplier of controllers for eMMC embedded memory used in smartphones and tablets, and the leading merchant supplier of controllers for client SSDs used in PCs and other applications. We also supply customized specialty SSD solutions for the Chinese hyperscale data center market and for high-performance industrial applications. We market our controllers under the “SMI” brand, our enterprise-grade SSDs under the “Shannon” brand, our single-chip industrial-grade SSDs under the “Ferri SSD” and “Ferri-eMMC” brands, specialty RF ICs under the “FCI” brand, and software-defined storage under the “Bigtera” brand.

Summary of Consolidated Financial Results

As discussed in more detail below, for the year ended December 31, 2018, compared to the year ended December 31, 2017, we delivered the following financial performance.

 

   

Total revenue increased by 1% to $530.3 million.

 

   

Gross profit as a percentage of revenue increased by 1.2% points to 49.2%.

 

   

Total operating expenses increased by less than 1% to $156.0 million.

 

   

Operating profit increased by 10% to $104.8 million.

 

   

Income tax expense as a percentage of income before income tax decreased by 14% points to 11%.

 

   

Diluted earnings per ADS increased by 30% to $2.71.

The increase in our revenue for the year ended December 31, 2018 was primarily the result of SSD controller sales increasing by about 30%, partially offset by eMMC plus UFS controller sales decreasing by about 10% and SSD solutions sales decreased by about 5%. SSD controller sales were nearly 40% of total revenue, eMMC plus UFS controller sales were in the range of 25% to 30% of total revenue and SSD solutions sales were nearly 20% of total revenue.

Total operating expenses were stable in 2018 primarily due to lower impairment loss of goodwill and intangible assets, offset by increased sales and marketing and other expenses. Impairment loss of goodwill and intangible assets was $6.3 million lower in 2018; in 2017 we recognized a one-time $10.3 million impairment loss of goodwill relating to our FCI acquisition and in 2018 we recognized a one-time $4.1 million impairment loss of goodwill and intangible assets related to our Bigtera acquisition. In 2017, we benefited from a one-time $1.9 million gain relating to the sale of our Shanghai property. Sales and marketing expenses were $3.4 million higher, primarily due to higher Bigtera headcount expenses, as well as larger expenditures for technical services and samples.

Our earnings per share increased primarily due to lower income taxes, increase in gross margin and lower operating expenses.

Principal Factors Affecting Our Results of Operations

Net sales. Our net sales consist primarily of sales of our products, after deducting sales discounts and allowances for returns.

Our net sales are denominated primarily in U.S. dollars. The percentages of our net sales by currency for the periods indicated are set forth in the following table:

 

     Year Ended December 31,

The length of our sales cycle, from the day purchase orders are received until products are shipped to customers, is dependent on the availability of our product inventories. If we do not have sufficient inventories on hand to meet customer demands, approximately three months are generally required from the day purchase orders are received until finished goods are manufactured and shipped to customers. This cycle can take up to six months during times when capacity at independent foundries is being fully utilized. The potential delays inherent in the manufacturing process increase the risk that we may not be able to fulfill a customer’s order on time. All of our sales are made by purchase orders. Because our practice, which is consistent with industry practice, allows customers to reschedule orders on relatively short notice, order backlog may not be a good indicator of our future sales.

Because many of our semiconductor solutions are designed for the mobile and computing devices markets, we expect our business to be subject to seasonality, with higher net sales generally in the second half of each year, when customers place orders to meet increased demand during year-end holiday seasons. However, our rapid sales growth and changing product mix in recent years could make assessment of the impact of seasonal factors on our business difficult.

Cost of sales. Our cost of sales consists primarily of the following costs:

 

   

cost of wafer fabrication;

 

   

assembly, testing and shipping costs of our semiconductors;

 

   

personnel and equipment costs associated with manufacturing support;

 

   

quality assurance;

 

   

cost of raw materials; and

 

   

write-down of inventory.

We engage independent foundries for the manufacturing and processing of our semiconductors. Our manufacturing cost is subject to the cyclical supply and demand conditions typical of the semiconductor industry. Our cost per wafer generally fluctuates with the availability of capacity at independent foundries. We believe that our cost of sales is substantially variable in nature.

Research and development expenses. Our research and development expenses consist primarily of employee salaries and related costs, stock-based compensation expense, fees paid for the use of intellectual properties and design tools developed by third parties, development cost of software, expenses for the design, development and

 

25


Table of Contents

testing of system architecture, new product or product alternatives, costs for the construction of prototypes, occupancy costs and depreciation on research and development related equipment. We expense research and development expenditures as they are incurred.

Sales and marketing expenses. Our sales and marketing expenses consist primarily of employee salaries and related costs, stock-based compensation expense, commissions paid to independent distributors and costs for our advertising and promotional activities.

General and administrative expenses. Our general and administrative expenses consist primarily of employee salaries and related costs, stock-based compensation expense, insurance premiums, professional fees and allowance for doubtful accounts.

Impairment of goodwill and intangible assets. We evaluate the recoverability of goodwill and intangible assets annually, or sooner if events or changes in circumstances indicate that the carrying amount may not be recoverable.

Amortization of acquired intangible assets. Amortization of acquired intangible assets relates to intangible assets, such as development technology, but excluding goodwill.

Gain from disposal of noncurrent assets held for sale. We sold an office building which was classified as noncurrent assets held for sale and recognized the gain from disposal.

Accounting for stock-based compensation. We grant both stock options and restricted stock units to our employees and members of the Board of Directors. The value of our restricted stock units is expensed over the vesting period and based on the grant date share price, less the present value of expected dividends during the vesting period, discounted at a risk-free interest rate.

Non-operating income and expenses. Our non-operating income and expenses include gains or losses on the sales of investments, interest from deposited cash or short-term investments, gains or losses on foreign exchange rates, impairment of long-term investments, interest paid on loans and capital leases, gain or loss on equity-method investment and other non-operating income and expenses not categorized above. We conduct an assessment on the value of our long-term investments quarterly and make corresponding write-downs as required to the value of the long-term investments.

Provision for income taxes. We must make certain estimates and judgments in determining income tax expenses for financial statement purposes. These estimates and judgments occur in the calculation of tax credits, benefits, deductions and allowance, and in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes, as well as the interest and penalties related to uncertain tax positions.

We have operations in several countries, which include Taiwan, China, Hong Kong, Macau and Korea, and determine income taxes for each of the jurisdictions where we operate.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States.

The preparation of our consolidated financial statements requires us to make estimates and judgments that affect the reported amount of assets, liabilities, net sales and expenses, and related disclosure of contingent assets

Table of Contents

and liabilities. We evaluate our estimates on an on-going basis, including those related to product returns and pricing allowances, allowances for doubtful accounts, inventories, business combinations, goodwill, long-lived assets, income taxes, litigation and contingencies. We base our estimates and judgments on our historical experience, knowledge of current conditions and our beliefs of what could occur in the future considering available information. Because our estimates may vary in each situation, our actual results may differ from our estimates under different assumptions and conditions.

Our management considers the following factors in reviewing our financial statements:

 

   

the selection of critical accounting policies; and

 

   

the judgments and other uncertainties affecting the application of those critical accounting policies.

The selection of critical accounting policies, the judgments and other uncertainties affecting the application of those policies and the sensitivity of reported results to changes in conditions and assumptions are factors to be considered when reviewing our financial statements. Our principal accounting policies are set forth in detail in Note 2 to our consolidated financial statements included elsewhere in this annual report.

We believe the following critical accounting policies affect our more significant judgments used in the preparation of our financial consolidated statements.

Revenue recognition. As a result of the adoption of the new revenue standard (ASC 606) on January 1, 2018, The Company enters into contracts that may include products that are capable of being distinct and accounted for as separate performance obligations. To date, the majority of the revenue has been generated by sales associated with products of storage and mobile communication, where a single performance obligation is identified in general. Revenue from services has been insignificant. Performance obligations associated with product sales transactions are generally satisfied when control passes to customers upon shipment or the written acceptance of the customers. Accordingly, product revenue is recognized at a point in time when control of the asset is transferred to the customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control of a product to a customer in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods. Some of the Company’s sales are made to distributors. Control passes to the distributor upon shipment, and terms and payment by the Company’s distributors is not contingent on resale of the product.

The Company grants certain distributors limited rights of return and price protection rights on unsold products. The return rights are generally limited to five percent of the monetary value of products purchased within the preceding six months, provided that the distributor places a corresponding restocking order of equal or greater value. An allowance for sales returns for distributors and all customers is recorded at the time of sale based on historical returns information available, management’s judgment and any known factors at the time the financial statements are prepared that would significantly affect the allowance. Price protection rights are based on the inventory products the distributors have on hand at the date the price protection is offered. The actual price adjustments to distributors incurred by the Company are minimal.

Allowance for doubtful accounts. We record an allowance for doubtful accounts based on our evaluation of the collectability of our accounts receivable. Normal payment terms are provided to customers and applied upon transfer of title. On an ongoing basis, we analyze the payment history of customer accounts, including recent customer purchases. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations to us, we record a specific allowance against amounts due to reduce the net recognized receivable to the amount we reasonably believe will be collected. For all other accounts receivable due from customers, we categorize accounts receivable and make provisions based on a percentage of each category. We determine these percentages by examining our historical collection experience and current trends in the credit quality of our customers as well as our internal credit policies. If the financial condition of our customers or economic

 

27


Table of Contents

conditions in general were to deteriorate, additional allowances may be required in the future and such additional allowances would increase our operating expenses and therefore reduce our operating income and net income.

Our allowance for trade-related doubtful accounts were approximately US$0.7 million, US$0.6 million and US$0.6 million as of December 31, 2016, 2017 and 2018, respectively, representing approximately 1.0%, 0.7% and 0.7% of our gross accounts receivables at the end of each respective periods.

Inventory valuation. We value inventories at the lower of cost or market value. Inventories are recorded at standard cost and adjusted to the approximate weighted-average cost at the balance sheet date. Market value represents the current replacement cost for raw materials, finished goods and work in process. We write down our inventory for estimated obsolescence or unmarketable inventory in an amount equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those we projected, additional inventory write-downs may be required. Inventory impairment charges establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable. In estimating our reserves for obsolescence, we primarily evaluate estimates based on the timing of the introduction of our new products and the quantities remaining of our old products and write down the value of inventory on hand in excess of the estimated demand. We wrote down US$3.0 million, US$0.7 million and US$2.1 million in 2016, 2017 and 2018, respectively, for estimated obsolete or unmarketable inventory.

Valuation of long-lived assets and intangible assets with finite useful life. We evaluate the recoverability of long-lived assets and intangible assets whenever events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of a long-lived asset is considered impaired when the sum of the anticipated undiscounted cash flows from such asset is separately identifiable and is less than the carrying value. If impairment occurs, a loss based on the excess of carrying value over the fair market value of the long-lived asset is recognized. Fair market value is determined by reference to quoted market prices, if available, or discounted cash flows, as appropriate. The impairment evaluations and the estimate of fair market value involve management estimates of assets’ useful lives and future cash flows. Actual useful lives and cash flows could be different from those estimated by management. This could have a material effect on our operating results and financial condition. No impairment losses were recognized in 2016 and 2017. In 2018, we wrote down the value of intangible assets by US$3.4 million. See Note 11 goodwill and acquired intangible assets in our financial statements.

Impairment of long-term investments. We evaluate the recoverability of long-term investments whenever events or changes in circumstances indicate the carrying value may not be recoverable. Impairment charges are determined based on the difference between our carrying value and our proportionate ownership of the investee company’s fair value at year end. In 2016, 2017 and 2018, we recognized long term investments impairment of US$13 thousand, US$120 thousand and nil, respectively, as a result of recurring operating losses and reduced forecasts of the investee companies which indicated that our investments were not recoverable within a reasonable period of time.

Business combinations. When we acquire businesses, we allocate the purchase price to tangible assets and liabilities and identifiable intangible assets acquired. Any residual purchase price is recorded as goodwill. The allocation of the purchase price requires management to make significant estimates in determining the fair values of assets acquired and liabilities assumed, especially with respect to intangible assets. These estimates are based on historical experience and information obtained from the management of the acquired companies. These estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital, and the synergistic benefits expected to be derived from the acquired business. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates.

Goodwill. We record goodwill when the consideration paid for an acquisition exceeds the fair value of net tangible and intangible assets acquired. We measure and test goodwill on an annual basis or more frequently if

 

28


Table of Contents

we believe indicators of impairment exist. Our impairment review process compares the fair value of the reporting unit in which the goodwill resides to its carrying value. We determined that our reporting units are equivalent to our operating segments or components of an operating segment for the purposes of completing our impairment test. Prior to fiscal 2017, we utilize a two-step approach to testing goodwill for impairment. The first step tests for possible impairment by applying a fair value-based test. In computing fair value of our reporting units, we use estimates of future revenues, costs and cash flows from such units. The second step, if necessary, measures the amount of such impairment by comparing the implied fair value of goodwill to its carrying value. If the carrying amount of goodwill exceeds its implied fair value, an impairment loss is recognized equal to that excess. In the fourth quarter of 2017, we elected to early adopt FASB Accounting Standard Update 2017-04, which removed step two from goodwill impairment test, in conjunction with our annual review for impairment. Estimating fair value is performed by utilizing various valuation approaches, such as income approach or market approach. The total of all reporting unit fair values was also compared to our market capitalization plus control premium for reasonableness.

In 2016, no impairment charges were recorded. In 2017 and 2018, we recorded an impairment charge of US$10.3 million and US$0.6 million because the carrying value of the mobile communication reporting unit and software defined storage unit, exceeded its fair value. The impairment charge was mainly attributable to a new project cancellation by a customer and delayed commercialization of a new product in 2017 and low achievement rate of revenue projection in 2018, respectively. The estimate of cash flow was based upon, among other things, certain assumptions about expected future operating performance such as revenue growth rates and operating margins used to calculate projected future cash flows, risk-adjusted discount rates, future economic and market conditions, and determination of appropriate market comparables. We based our fair value estimates on assumptions we believed to be reasonable but that are unpredictable and inherently uncertain. The long-term financial forecast represented the best estimate that we had at that time and we believed that its underlying assumptions were reasonable. However, actual performance in the near-term and longer-term could be materially different from the forecast, which could impact future estimates of fair value of our reporting units and may result in a charge to earnings in future periods due to the potential for further write-down of goodwill in connection with future impairment tests.

Accounting for income taxes. In preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. We are tax resident in numerous taxing jurisdictions around the world and have identified our major tax jurisdictions as Taiwan, Hong Kong, Korea, Macau and China with statutory tax rate of 20%, 16.5%, 11%, 12% and 25%, respectively. This process involves estimating our actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income within the relevant jurisdiction and, to the extent we believe that recovery is not likely, we must establish a valuation allowance. The total amount of valuation allowance as of December 31, 2016, 2017 and 2018 was US$20.8 million, US$19.1 million and US$20.0 million, respectively. We provide for a valuation allowance to the extent we believe that it is more likely than not that the deferred tax assets will not be recovered from future taxable income. Realization of the future tax benefits related to the deferred tax assets is dependent on many factors, including our ability to generate taxable income within the period during which the temporary differences reverse, the outlook for the economic environment in which we operate, and the overall future industry outlook. Should we determine that we would not be able to realize all or part of our net deferred tax asset in the future, an additional allowance for the deferred tax asset would be charged to income in the period the determination was made.

We utilize a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The total amount of unrecognized tax benefits as of

 

29


Table of Contents

December 31, 2016, 2017 and 2018 was US$10.3 million, US$15.1 million and US$18.7 million, respectively. As of December 31, 2017 and 2018, US$3.4 million and US$4.1 million, respectively, of interest and penalties were accrued. Fiscal years 2013 through 2018 remain subject to examination by the US Internal Revenue Service and other foreign tax jurisdictions. The ultimate outcome of tax matters may differ from our estimates and assumptions. Unfavorable settlement of any particular issue would require the use of cash and could result in increased income tax expense. Favorable resolution could result in reduced income tax expense. Within the next 12 months, we do not expect that our unrecognized tax benefits would change significantly. See Note 16 to the Consolidated Financial Statements for further information regarding changes in unrecognized tax benefits during 2018.

Legal Contingencies. From time to time, we are involved in legal actions or other third-party assertions arising in the ordinary course of business. There can be no assurance these actions or other third-party assertions will be resolved without costly litigation, in a manner that does not adversely impact our financial position, results of operations or cash flows or without requiring royalty payments in the future, which may adversely impact gross margins. We record a liability when it is probable that a loss has been incurred and the amount can be reasonably estimated. In determining the probability of a loss and consequently, determining a reasonable estimate, management is required to use significant judgment. Given the uncertainties associated with any litigation, the actual outcome can be different than our estimates and could adversely affect our results of operations, financial position and cash flows. See Item 8: “Legal Proceedings”.

Interest expense. Interest expense decreased to approximately US$378 thousand for the year ended December 31, 2018 from approximately US$423 thousand for the year ended December 31, 2017 because we repaid a bank loan before the end of the year.

Foreign exchange gain (loss), net. For the year ended December 31, 2018, we incurred foreign exchange losses of US$615 thousand, compared with losses of US$157 thousand for the year ended December 31, 2017. We do not engage in any hedging activities.

As of December 31, 2018, we had approximately US$288.6 million in cash, cash equivalents and short-term investments, a decrease of $77.8 million from December 31, 2017. We maintain our cash balances in bank deposits and in money market instruments. We do not engage in any currency hedging activities. Our short-term investments consist primarily of principal protected notes that we trade.

We believe our existing cash balances and short-term investments, together with cash we expect to generate from operating activities, will be sufficient to meet our anticipated cash needs for at least the next 12 months. Our future capital requirements will depend on many factors, including the level of our net sales, the timing and extent of spending to support product development efforts, the expansion of sales and marketing activities, the timing of introductions of new products, the costs to ensure access to adequate manufacturing capacity, the continuing market acceptance of our products, availability of attractive acquisition and investment opportunities, dividend payments, share repurchases and construction of our office building. We could be required, or could elect, to seek additional funding through public or private equity or debt financing, and additional funds may not be available on terms acceptable to us or at all.

years, with one-third of the directors (or, if their number is not a multiple of three, the number nearest to but not greater than one-third) subject to re-election at each annual general meeting of shareholders (chairman and managing director not subject to retirement by rotation nor to be taken into account in determining the number of directors to retire), unless the director was appointed by the board of directors, in which case such director holds office until the next annual meeting of shareholders at which time such director is eligible for re-election.

All of our executive officers are appointed by and serve at the discretion of our board of directors.

Under our memorandum and articles of association, indemnification is not available to any matter in respect of any fraud, dishonesty, willful misconduct or bad faith which may attach to any of them.

Compensation of Directors and Executive Officers

For the year ended December 31, 2018, the aggregate compensation to our directors and senior executive officers was approximately US$ 4.73 million. In 2018, we granted options and restricted stock units to our executive officers as a group to acquire an aggregate of 229,220 ordinary shares. The options and restricted stock units granted to our executive officers and non-executive directors are subject to the same vesting conditions as those of our employees.

Service Contracts

We currently do not have service contracts with our directors.

Share-Based Compensation Plans and Option Grants

In April 2005, our board of directors and shareholders adopted our 2005 Incentive Plan. Our shareholders approved our Amended and Restated 2005 Incentive Plan (referred to in this report as the “2005 Plan”) at our Annual General Meeting in August 2006, including an amendment to increase the authorized number of shares available for issuance under the plan from 10,000,000 shares to 25,000,000 shares. In 2009, the board of directors amended the 2005 Plan to increase the authorized shares available for issuance under the 2005 Plan to 40,000,000 shares. The 2005 Plan expired by its terms on April 22, 2015. On June 3, 2015, the board of directors adopted the 2015 Incentive Plan (the “2015 Plan” and together with the 2005 Plan, the “Plans”). The 2015 Plan reserved 20,000,000 shares of ordinary shares for issuance upon exercise of stock options and restricted stock units. The Plans provide for the grant of stock options, stock bonuses, restricted stock awards, restricted stock units and stock appreciation rights, which may be granted to our employees (including officers), directors and consultants.

Share Reserve. The aggregate number of ordinary shares that may be issued pursuant to awards granted under the 2005 Plan could not exceed 40,000,000 shares and the aggregate number of ordinary shares that may be issued pursuant to awards granted under the 2015 Plan will not exceed 20,000,000, inclusive of ordinary shares issuable upon exercise of awards previously granted under the Silicon Motion, Inc. Guidelines for Issuance and Subscription of Employee Stock Option, which options we have, subject to the consent of the respective option-holders, agreed to assume in the share exchange.

The following types of shares issued under the Plans may again become available for the grant of new awards under the Plans: restricted stock issued under the Plans that is forfeited or repurchased by us prior to it becoming fully vested; shares withheld for taxes; shares tendered to us to pay the exercise price of an option; and shares subject to awards issued under the Plans that have expired or otherwise terminated without having been exercised in full.

Table of Contents

Administration. The board of directors will administer the Plans and may delegate this authority to administer the plan to a committee. Subject to the terms of the Plans, the plan administrator, which is our board of directors or its authorized committee, determines recipients, grant dates, the numbers and types of stock awards to be granted and the terms and conditions of the stock awards, including the period of their exercisability and vesting. Subject to certain limitations, the plan administrator will also determine the exercise price of options granted, the purchase price for restricted stock and restricted stock units, and, if applicable, the strike price for stock appreciation rights.

Capitalization adjustments. In the event of a dividend or other distribution (whether in the form of cash, ordinary shares, other securities, or other property), recapitalization, stock split, reorganization, merger, consolidation, exchange of our ordinary shares or our other securities, or other change in our corporate structure, the board of directors may adjust the number and class of shares that may be delivered under the Plans and the number, class and price of the shares covered by each outstanding stock award.

Changes in control. In the event of a change in control of the company, all outstanding options and other awards under the Plans may be assumed, continued or substituted for by any surviving or acquiring entity. If the surviving or acquiring entity elects not to assume, continue or substitute for such awards, the vesting of such awards held by award holders whose service with us or any of our affiliates has not terminated will be accelerated and such awards will be fully vested and exercisable immediately prior to the consummation of such transaction, and the stock awards shall automatically terminate upon consummation of such transaction if not exercised prior to such event.

Amendments to 2005 Plan in 2009 and 2010. In 2009, our board of directors amended the 2005 Plan to (i) increase the authorized shares to 40,000,000 as discussed above and (ii) allow certain unilateral amendments to outstanding options and RSU grants. Shareholder approval for such amendments was not required under Cayman law and we used the home-country exemption for foreign private issuers under Nasdaq rules to effect such amendments without a shareholder vote. In 2009, the Company cancelled 1,221,875 RSUs. There were no changes to outstanding options in 2009. In 2010, the Company exchanged 4,369 thousand stock options for 3,785 thousand new stock options with a similar value.

Future amendments and termination. The board of directors may amend (subject to shareholder approval if required by applicable law), suspend or terminate the 2015 Plan at any time. The 2015 Incentive Plan will terminate pursuant to its terms on June 3, 2025.

Share Ownership

Under U.S. securities law, a person is deemed to be a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of such security, or “investment power,” which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be the beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Under these rules, more than one person may be deemed a beneficial owner of securities as to which such person has no economic interest.

There were 146,085,104 of our ordinary shares outstanding as of March 31, 2019. The following table sets forth information with respect to the beneficial ownership of our ordinary shares as of March 31, 2019, less otherwise indicated in the footnotes, by each of our directors and officers:

Related Party Transactions

In early 2019, during the due diligence process to sell the Company’s FCI subsidiary to Dialog Semiconductor—see “Item 8. “Recent Developments”—it was determined that Jeonse housing leases in Korea were arranged between the lessee, FCI, and lessors, certain FCI employees, including three of our executive officers, or their immediate relatives. These leases, in place from 2007 to 2019, involve the lessee depositing funds equivalent to approximately 80% of the market value of the property interest-free with the lessor in exchange for rent-free housing for the employees. Deposited funds are returned to the lessee in full at the end of the lease period. The total value of the leases in 2016, 2017 and 2018 were $1.5 million, $1.6 million and $1.5 million, of which $1.1 million, $1.3 million and $1.2 million were with executive officers or their immediate relatives, respectively. The Jeonse leases have all been terminated, and the Company intends to complete the sale of FCI in the second quarter, subject to Korean government approvals. The Company intends to take additional steps to improve its internal control structure to reduce the risk of undisclosed related party transactions.

Legal Proceedings

As an active operating company, we are subject to legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business. Although the outcome of such proceedings and claims cannot be predicted with certainty, management does not believe that the outcome of any of these matters will have a material adverse effect on our business, results of operations, financial position or cash flows. Any litigation, however, involves potential risk and potentially significant litigation costs, and therefore there can be no assurance that any litigation which is now pending or which may arise in the future would not have such material adverse effect on our business, financial position, results of operations or cash flows.

All American Semiconductor, Inc. (“All American” or “AASI”) was a former distributor for the Company. On April 25, 2007, All American filed for Chapter 11 bankruptcy protection. At the time of the filing, the Company had US$256 thousand of unpaid accounts receivable from All American. On April 17, 2009 SMI USA and related entities were named as defendants in an adversary proceeding filed by the AASI Creditor Liquidating Trust (“CLT”) in the bankruptcy case pending in the U.S. Bankruptcy Court for the Southern District of Florida. The CLT was seeking the return of allegedly avoidable transfers in the amount of US$854 thousand. SMI USA filed an answer and affirmative defenses. In March 2010, SMI USA settled with the CLT by paying the amount of US$220 thousand and on April 1, 2010, the Bankruptcy Court granted the motion to approve stipulations to compromise controversy. On August 23, 2010, the Court entered an order dismissing the adversary proceeding. In June 2011, Liquidating Trustee for the CLT filed the AASI Creditor Liquidating Trustee’s Seventeenth Omnibus Objection to Claims but in August 2011, withdrew it with respect to SMI USA’s proof of claim. As a holder of allowed claims, we are entitled to receive distribution pursuant to the bankruptcy plan. As of December 31, 2017, we received total distributions of US$265 thousand from the CLT and this case is officially closed.

Significant Changes

No significant changes have occurred since the date of our audited consolidated financial statements.

Recent Developments

 

a)

Sale of FCI

In January 2019, the board of directors of the Company approved the sale of FCI, our specialty RF IC product line for the Mobile Communications market. On March 7, 2019, the Company entered into a definitive agreement with Dialog Semiconductor Plc for the sale of FCI for US$45 million. The transaction is expected to close in the second quarter of 2019, subject to Korean government approvals.

 

b)

Sale of ProGrade investment

In April 2019, the board of directors approved the sale of the Company’s 49.0% equity interest in ProGrade for $1.7 million. The sale is expected to close in the second quarter of 2019.

 

c)

Shannon Impairment Risk

In April 2019, key customers of our Shannon SSDs notified the Company that their revised full-year 2019 procurement forecasts will be significantly lower than what they had provided to us in January 2019. As a result, we reduced our Shannon SSD sales forecast to a level meaningfully below what we had planned in January as part of our annual operating plan. The primary reasons of the recently reduced sales forecast include: (i) increasingly risk-adverse customers have reduced procurement plans relating to SSD solutions based on new, less mature technologies such as ours, (ii) weakening economic conditions in China have caused Chinese data center operators to postpone expansion plans and reduce SSD procurement forecasts, including from us, and

 

50


Table of Contents

(iii) NAND prices have fallen more than we had expected and could fall further, and this will result in less revenue received for the same petabyte of Shannon SSDs that we sell.

The reduced sales forecast represents a triggering event which will require the reevaluation of the reporting unit’s goodwill and intangible assets in the second quarter of 2019. Depending on further development of the situation and factors relevant to a revised financial forecast of the Shannon reporting unit, the impairment assessment may result in impairment of goodwill and of certain intangible assets; however, the Company cannot estimate the amount or a reasonable range of amounts of such impairments, if any, at this time. As of December 31, 2018, the carrying value of the reporting unit’s goodwill was $33.2 million and intangible assets were $1.0 million.

Taxation

United States Federal Income Taxation

The following discussion summarizes certain U.S. federal income tax consequences to a U.S. Holder, as defined below, who purchases our ADSs and ordinary shares. This discussion assumes that investors will hold their ADSs or ordinary shares as capital assets (generally, property held for investment). This discussion does not discuss all aspects of U.S. federal income taxation which may be important to particular investors in light of their individual circumstances, including investors subject to special taxation, such as:

 

   

banks and financial institutions;

 

   

brokers and dealers in securities or currencies;

 

   

insurance companies;

 

   

tax-exempt organizations and retirement plans;

 

   

grantor trusts;

 

   

S corporations;

 

   

persons holding ADSs or ordinary shares as part of hedging, conversion, constructive sale, straddle or other integrated transactions;

 

   

persons who acquired their ordinary shares upon the exercise of employee stock options or otherwise as compensation;

 

   

persons who have elected the mark-to-market method of accounting;

 

   

persons who own 10% or more of our ADSs or shares;

 

   

real estate investment trusts or regulated investment companies;

 

   

U.S. persons whose “functional currency” is not the U.S. dollar;

 

   

certain former citizens or long-term residents of the United States; and

 

   

Non-U.S. Holders (as defined below).

This discussion is based in part on representations by the depositary and assumes that each obligation under the deposit agreement and any related agreement will be performed in accordance with its terms. Furthermore,

 

52


Table of Contents

the discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and U.S. Treasury regulations, rulings and judicial decisions hereunder as of the date hereof. Such authorities are subject to change, possibly on a retroactive basis, which may result in U.S. federal income tax consequences different from those discussed below.

A person considering an investment in our ADSs or ordinary shares is urged to consult its tax advisor concerning U.S. federal, state, local and non-U.S. income and other tax consequences.

A U.S. Holder is a beneficial owner of ADSs or ordinary shares that is for U.S. federal income tax purposes:

 

   

a citizen or resident individual of the United States;

 

   

a corporation or other entity taxable as a corporation created or organized in or under the laws of the United States, any state thereof, or the District of Columbia;

 

   

an estate the income of which is subject to U.S. federal income taxation, regardless of its source; or

 

   

a trust if it is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust or has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

A beneficial owner of ADSs or ordinary shares that is not a U.S. Holder is referred to herein as a “Non-U.S. Holder.” If a partnership or limited liability company treated as a partnership for U.S. federal income tax purposes holds ADSs or ordinary shares, the tax treatment of a partner or member will generally depend on the status of the partner or member and the activities of the partnership or such limited liability company. A partner of a partnership or a member of such a limited liability company holding ADSs or ordinary shares is urged to consult its tax advisors regarding an investment in our ADSs or ordinary shares.

ADSs. In general, for U.S. federal income tax purposes, a U.S. Holder of ADSs will be treated as the owner of the underlying ordinary shares that are represented by such ADSs. Deposits and withdrawals of ordinary shares in exchange for ADSs will not be subject to U.S. federal income taxation.

Distributions on ADSs or ordinary shares. Unless the passive foreign investment company rules, as discussed below, apply, the gross amount of the distributions in respect of the ADSs or ordinary shares will be subject to tax as dividend income to the extent of our current and accumulated earnings and profits, as determined under U.S. federal income tax principles. Subject to certain limitations, dividends paid to non-corporate U.S. Holders, including individuals, may be eligible for a reduced rate of taxation if we are deemed to be a “qualified foreign corporation” for U.S. federal income tax purposes, provided that such holder satisfies certain holding period requirements with respect to the ownership of our ADSs or ordinary shares. Subject to the exceptions discussed below, a corporation is a qualified foreign corporation if it is:

 

   

a foreign corporation that is eligible for the benefits of a comprehensive income tax treaty with the United States that includes an exchange of information program; or

 

   

a foreign corporation if its stock with respect to which a dividend is paid or its ADSs backed by such stock are readily tradable on an established securities market within the United States.

The Cayman Islands does not currently have a comprehensive income tax treaty with the United States. A foreign corporation (even if it is described above) does not constitute a qualified foreign corporation if, for the taxable year in which the dividend is paid or the preceding taxable year, the foreign corporation is or was a passive foreign investment company. Although we believe that we are a qualified foreign corporation because the ADSs will be traded on an established U.S. securities market and, as discussed below, we believe that we were not a passive foreign investment company for our 2018 tax year, no assurance can be given in this regard. In addition, our status as a qualified foreign corporation may change. A U.S. Holder that exchanges its ADSs for ordinary shares may not be eligible for the reduced rate of taxation on dividends if the ordinary shares are not deemed to be readily tradable on an established securities market within the United States.

 

53


Table of Contents

Dividends will be includable in a U.S. Holder’s gross income on the date actually or constructively received by the depositary, in the case of ADSs or, in the case of ordinary shares, by such U.S. Holder. These dividends will not be eligible for the dividends-received deduction generally allowed to U.S. corporations in respect of dividends received from other U.S. corporations.

To the extent we pay dividends on the ADSs or ordinary shares in a currency other than the U.S. dollar, the U.S. dollar value of such dividends should be calculated by reference to the exchange rate prevailing on the date of actual or constructive receipt of the dividend, regardless of whether the foreign currency is converted into U.S. dollars at that time. If the foreign currency is converted into U.S. dollars on the date of actual or constructive receipt of such dividends, the tax basis of the U.S. Holder in such foreign currency will be equal to its U.S. dollar value on that date and, as a result, the U.S. Holder generally should not be required to recognize any foreign currency exchange gain or loss. Dividends paid in respect of the ADSs or ordinary shares generally will be treated as income from sources outside the United States.

To the extent that the amount of any distribution exceeds our current and accumulated earnings and profits, the distribution will first be treated as a tax-free return of capital, causing a reduction in the adjusted basis of the ADSs or ordinary shares, and the balance in excess of adjusted basis will be taxed as capital gain.

Sale, exchange or other disposition of ADSs or ordinary shares. Unless the passive foreign investment company rules, as discussed below, apply, upon the sale, exchange or other disposition of ADSs or ordinary shares a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount realized upon the sale, exchange or other disposition and the adjusted tax basis of the U.S. Holder in the ADSs or ordinary shares. The capital gain or loss generally will be long-term capital gain or loss if, at the time of sale, exchange or other disposition, the U.S. Holder has held the ADS or ordinary share for more than one year. Net long-term capital gains of non-corporate U.S. Holders, including individuals, are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Any gain or loss that a U.S. Holder recognizes generally will be treated as gain or loss from sources within the United States for U.S. foreign tax credit limitation purposes.

Additional tax on net investment income. An additional 3.8% federal income tax may be assessed on net investment income (including dividends, other distributions, and gain realized on the sale of ADSs or ordinary shares) earned by certain U.S. Holders. This tax does not apply to U.S. Holders who hold ADSs or ordinary shares in the ordinary course of certain trades or businesses.

Passive foreign investment company rules. In general, we will be classified as a passive foreign investment company for any taxable year in which either (a) at least 75% of our gross income is passive income or (b) at least 50% of the value (determined on the basis of a quarterly average) of our assets is attributable to assets that produce or are held for the production of passive income. For this purpose, passive income generally includes dividends, interest, royalties, rents (other than rents and royalties derived in the active conduct of a trade or business and not derived from a related person), annuities and gains from assets that produce passive income. If we own directly or indirectly at least 25% by value of the equity shares of another corporation, we will be treated for purposes of the passive foreign investment company tests as owning a proportionate share of the assets of the other corporation, and as receiving directly a proportionate share of the other corporation’s income.

We believe, based on our present and projected composition of our income and valuation of our assets, we were not classified as a passive foreign investment company for U.S. federal income tax purposes for our 2018 tax year, although no assurance can be given in this regard. Whether we are a passive foreign investment company for any particular taxable year is determined on an annual basis and will depend on the composition of our income and assets, including goodwill. The calculation of goodwill will be based, in part, on the then market value of our capital stock, which is subject to fluctuation. Accordingly, there can be no assurance that we will not be classified as a passive foreign investment company in the current or any future taxable year.

 

54


Table of Contents

If we are a passive foreign investment company for any taxable year during which a U.S. Holder has an equity interest in our company, unless the U.S. Holder makes a mark-to-market election as discussed below, such U.S. Holder will be subject to special tax rules in any future taxable year regardless of whether we are classified as a passive foreign investment company in such future years with respect to (a) “excess distributions” and (b) gain from the disposition of stock. Excess distributions are defined generally as the excess of the amount received with respect to the equity interests in the taxable year over 125% of the average annual distributions received in the shorter of either the three previous years or a U.S. Holder’s holding period before the taxable year and must be allocated ratably to each day of the U.S. Holder’s holding period. The amount allocated to the current taxable year or any year before we became a passive foreign investment company will be included as ordinary income in a U.S. Holder’s gross income for that year. The amount allocated to other prior taxable years will be taxed as ordinary income at the highest rate in effect for a U.S. Holder in that prior year and the tax is subject to an interest charge at the rate applicable to deficiencies in income taxes. The entire amount of any gain realized upon the sale or other disposition of the equity interests will be treated as an excess distribution made in the year of sale or other disposition and as a consequence will be treated as ordinary income and, to the extent allocated to years prior to the year of sale or disposition with respect to which we were a passive foreign investment company, will be subject to the interest charge described above.

In certain circumstances, instead of being subject to the excess distribution rules discussed above, a U.S. Holder may make an election to include gain on the ADSs or ordinary shares of a passive foreign investment company as ordinary income under a mark-to-market method, provided that the ADSs or ordinary shares are regularly traded on a qualified exchange. Under current law, the mark-to-market election is only available for ADSs or ordinary shares that are regularly traded within the meaning of U.S. Treasury regulations on certain designated U.S. exchanges and foreign exchanges that meet trading, listing, financial disclosure and other requirements to be treated as a qualified exchange under applicable U.S. Treasury regulations. The Nasdaq Stock Market is a qualified exchange. The ordinary shares may not be eligible for mark-to-market treatment under the foregoing rule even if the ADSs otherwise satisfy the applicable requirement.

If a U.S. Holder makes a mark-to-market election, the U.S. Holder will include each year as ordinary income, rather than capital gain, the excess, if any, of the fair market value of the U.S. Holder’s ADSs or ordinary shares at the end of the taxable year over such U.S. Holder’s adjusted basis in the ADSs (or ordinary shares, if applicable) and will be permitted an ordinary loss in respect of the excess, if any, of the adjusted basis of these ADSs or ordinary shares over their fair market value at the end of the taxable year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. A U.S. Holder’s basis in the ADSs or ordinary shares will be adjusted to reflect any such income or loss amounts. Any gain or loss on the sale of the ADSs or ordinary shares will be ordinary income or loss, except that this loss will be ordinary loss only to the extent of the previously included net mark-to-market gain.

If we are a passive foreign investment company, then under certain circumstances a U.S. Holder must file Internal Revenue Service Form 8621.

Information Reporting and Back-up Withholding. The Foreign Account Tax Compliance Act (“FATCA”) generally requires that individuals that hold certain specified foreign financial assets worth in excess of certain thresholds of $50,000 or more, depending on the individual’s circumstances, report such ownership to the IRS using IRS Form 8938. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a foreign entity. A U.S. Holder may be subject to this reporting requirement unless such holder’s ADSs or ordinary shares are held in an account at a domestic financial institution. The penalty for failing to file Form 8938 is substantial.

U.S. holders generally are subject to information reporting requirements with respect to dividends on, or proceeds from the disposition of, our ordinary shares. In addition, a U.S. holder may be subject, under certain circumstances, to backup withholding at a rate of up to 24% with respect to dividends paid on, or proceeds from

 

55

the disposition of, our ordinary shares unless the U.S. holder provides proof of an applicable exemption or correct taxpayer identification number, and otherwise complies with the applicable requirements of the backup withholding rules. A U.S. holder of our ordinary shares who provides an incorrect taxpayer identification number may be subject to penalties imposed by the IRS. Amounts withheld under the backup withholding rules are not an additional tax and may be refunded or credited against the U.S. holder’s U.S. federal income tax liability, provided the required information is furnished to the IRS.

A U.S. Holder is urged to consult its tax advisor concerning the U.S. federal income tax consequences of an investment in our ADSs or ordinary shares if we are or become a passive foreign investment company, including the possibility of making a mark-to-market election.

Cayman Islands Taxation

The Cayman Islands currently levy no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to our company levied by the Government of the Cayman Islands except for stamp duties that may be applicable on instruments executed in, or after execution brought within the jurisdiction of, the Cayman Islands. The Cayman Islands are not party to any double taxation treaties. There are no exchange control regulations or currency restrictions in the Cayman Islands.

We have, pursuant to Section 6 of the Tax Concessions Law (1999 Revision) of the Cayman Islands, obtained an undertaking from the Governor-in-Council that:

 

   

no law which is enacted in the Cayman Islands imposing any tax to be levied on profits or income or gains or appreciation applies to us or our operations; and

 

   

the aforesaid tax or any tax in the nature of estate duty or inheritance tax are not payable on our ordinary shares, debentures or other obligations.

The undertaking that we have obtained is for a period of 20 years from March 1, 2005.

In December 2018, the Cayman Islands published The International Tax Co-operation (Economic Substance) Law in response to the OECD’s Base Erosion and Profit Shifting (BEPS) standards. Silicon Motion Technology Corp. is a Cayman company and may be affected by the new law’s economic substance requirements, which require companies registered in the Cayman Islands to show business activity in the Caymans, tax residency elsewhere, or be subject to penalties. Economic substance requirements will apply to existing Cayman companies, such as our company, from July 1, 2019. See “Risk Factor — The enactment of legislation implementing changes in taxation of international business activities, the adoption of other tax reform policies or change in tax legislation or policies could materially impact our financial position and results of operations.”

Documents on Display

We have previously filed with the SEC our registration statement on Form F-6 under the Securities Act of 1933, as amended (the “Securities Act”) with respect to our ADSs.

We are subject to the periodic reporting and other informational requirements of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”). Under the Exchange Act, we are required to file reports and other information with the SEC. Specifically, we are required to file annually a Form 20-F no later than four months after the close of each fiscal year, which is December 31. As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of quarterly reports and proxy statements, and our officers, directors, and principal shareholders are exempt from the reporting and short-swing profit recovery provisions of Section 16 of the Exchange Act.

ITEM 11.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk. Our exposure to changes in interest rates is limited to interest income generated by our cash deposited with banks and short-term investments maintained in bond funds, principal protected notes and interest expenses payable on our bank loans. We have not entered into any interest rate swap transactions. We do not believe that a 1% change in interest rates would have a significant impact on our operations.

Foreign currency risk. Since 2012, we consider our direct exposure to foreign exchange rate fluctuations to be minimal. Prior to 2012, we reported our financial results in NT dollars and our direct exposure to foreign exchange rate fluctuations was more significant. Gains or losses from foreign currency re-measurement are included in “Non-Operating Income (Expenses)” in our Consolidated Financial Statements. The impact of foreign currency transaction gain or loss included in determining net income (loss) for 2016, 2017 and 2018 was US$(0.7) million, US$(0.2) million and US$(0.6) million, respectively. Currently, the majority of our revenue, cost of sales, accounts receivable, and accounts payable are denominated in U.S. dollars. Increases in the value of the U.S. dollar relative to other currencies would make our products more expensive, which could negatively impact our ability to compete. Conversely, decreases in the value of the U.S. dollar relative to other currencies could result in our suppliers raising their prices in order to continue doing business with us. Fluctuations in currency exchange rates could harm our business in the future. We do not utilize foreign exchange derivatives contracts to protect against changes in foreign exchange rates.

Also refer to “Risk Factors — We are subject to risks associated with international operations which may harm our business.”

Investment Risk. We invest in equity instruments of privately held companies. We have minority stake equity investments in Cashido, Vastview and Deep Vision, private companies related to the semiconductor and other technology industries. These investments are accounted for under the cost method because our ownership is less than 20% and we do not have the ability to exercise significant influence over the operations of these companies. In 2018, we invested in 49% of the equity of ProGrade and accounted for this investment under the equity method. As of December 31, 2018, the aggregate carrying value of these investments on our balance sheet was US$4.2 million. We monitor these investments for impairment and make appropriate reductions in carrying value when an impairment is deemed to be other than temporary. The impairments losses for the years ended on December 31, 2016, 2017 and 2018 were US$13 thousand, US$120 thousand and nil, respectively.

As of December 31, 2018, we also had the short-term investments of US$3.6 million in principal protected notes.

 

ITEM 12.

DESCRIPTION OF SECURITIES OTHER THAN EQUITY SECURITIES

Depositary Fees and Charges. For the year-ended December 31, 2018, we received from our depositary bank a reimbursement of US$0.8 million, net of withholding tax, for our continuing annual stock exchange listing fees and our other expenses incurred in connection with maintaining and promoting our ADS program. In addition, the depositary bank has agreed to reimburse us annually for a fixed number of years for our continuing annual stock exchange listing fees and our other expenses incurred in connection with maintaining and promoting our ADS program. The amount of annual reimbursements is subject to certain limits.

CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2018. Disclosure controls and procedures are designed to ensure that the material financial and non-financial information required to be disclosed in this annual report on Form 20-F and filed with the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. The evaluation was performed with the participation of our key corporate senior management, and under the supervision of our Chief Financial Officer, or CFO, Riyadh Lai, and our President and Chief Executive Officer, or CEO, Wallace Kou. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable, rather than absolute, assurances of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the foregoing, our management, including our CEO and CFO, concluded that our disclosure controls and procedures were effective.

Management’s Report on Internal Control over Financial Reporting

Our management, including our CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined under Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States. Internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets, (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with appropriate authorizations; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.

Our management assessed the effectiveness of our internal control over financial reporting as of the end of the period covered by this annual report based on the criteria set forth in the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Their assessment included an evaluation of the design of our internal control over financial reporting and testing of the operational effectiveness of our internal control over financial reporting. Based on that assessment, our management concluded that as of December 31, 2018 the company’s internal control over financial reporting was effective.

Deloitte & Touche, the independent registered public accounting firm that audited our consolidated financial statements included in this annual report has issued an attestation report regarding internal control over financial reporting.

Changes in Internal Control over Financial Reporting

During 2018, no change to our internal control over financial reporting occurred that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

All internal control systems no matter how well designed and implemented have inherent limitations. Even systems determined to be effective may not prevent or detect misstatements or fraud and can only provide reasonable assurance with respect to disclosure and financial statement presentation and reporting. Additionally, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changed conditions and the degree of compliance with the policies or procedures may deteriorate.

Attestation Report Of The Independent Registered Public Accounting Firm

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of

Silicon Motion Technology Corporation

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Silicon Motion Technology Corporation and subsidiaries (the “Company”) as of December 31, 2018, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2018, of the Company and our report dated May 15, 2019 expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of

Silicon Motion Technology Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Silicon Motion Technology Corporation and subsidiaries (the “Company”) as of December 31, 2017 and 2018, the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2018, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated May 15, 2019, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

SILICON MOTION TECHNOLOGY CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(In Thousands)

1. THE COMPANY

Silicon Motion Technology Corporation (“SMTC”, collectively with its subsidiaries the “Company”) is the global leader in selling NAND flash controllers for solid state storage devices and the merchant leader in supplying SSD controllers. The Company has the broadest portfolio of controller technologies and its controllers are widely used in embedded storage products such as SSDs and eMMC and UFS devices, which are found in smartphones, PCs and commercial and industrial applications. It has shipped over six billion NAND controllers in the last ten years, more than any other company in the world. The Company also supplies customized high-performance hyperscale data center and industrial SSD solutions. The Company’s customers include most of the NAND flash vendors, storage device module makers and leading OEMs. For further information on Silicon Motion, visit us at www.siliconmotion.com.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements have been prepared in accordance with U.S. GAAP. The consolidated financial statements include the accounts of SMTC and its wholly-owned subsidiaries. The Company owns 100% of the outstanding shares in all of its subsidiaries. All significant intercompany balances and transactions have been eliminated upon consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect certain reported amounts and disclosures. The actual results could differ from those estimates.

Concentration of Credit Risk and Significant Customers

Financial instruments that potentially subject the Company to a significant concentration of credit risk consist principally of cash equivalents, short term investments and accounts receivable. Cash, cash equivalents and short-term investments balances are maintained with high quality financial institutions, the composition and maturities of which are regularly monitored by management. The Company believes that the concentration of credit risk in its trade receivables, is substantially mitigated by the Company’s credit evaluation process, relatively short collection terms and the high level of credit worthiness of its customers. The Company performs ongoing credit evaluations of its customers’ financial conditions and limits the amount of credit extended based upon payment history and the customer’s current credit worthiness. The Company regularly reviews the allowance for bad debt and doubtful accounts by considering factors such as historical experience, credit quality, age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay.

Historically, a relatively small number of customers have accounted for a significant portion of our net revenue. Sales to one customer in 2016, and two customers in 2017 and 2018 accounted for 10% or more of the Company’s net sales, and these sales represented 28%, 39% and 34% of the Company’s net sales in 2016, 2017 and 2018, respectively. In 2016, the significant customer was SK Hynix and in 2017 and 2018, SK Hynix and Intel. The Company’s top ten customers in 2016, 2017 and 2018 accounted for approximately 75%, 72% and 69% of net sales, respectively.

Fair Value of Financial Instruments

The carrying amount of the Company’s financial instruments, including cash and cash equivalents, notes and accounts receivable and notes and accounts payables approximates fair value due to the short-term maturity of the instruments. Fair values of short-term investments represent quoted market prices, if available. If no quoted market prices are available, fair values are estimated based on discounted cash flow, or other valuation techniques. Long-term investments in privately-held companies with no readily determinable market value are recorded using the cost method, since the cost of obtaining verifiable fair value is unreasonably high. Upon adoption of Accounting Standard Update No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”) starting January 1, 2018, these investments are measured at cost less impairment, if any, plus or minus any changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Any resulting change in carrying amount would be reflected in net income. The Company’s long-term liabilities approximate their fair values as they contain interest rates that vary according to market interest rates.

Fair value is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that assets or liability. The fair value should be calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the Company. A three-tier fair value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value. The hierarchy prioritizes the inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each fair value measurement is reported in one of the three levels which is determined by the lowest level input that is significant to the fair value measurement in its entirety. These levels are:

Level 1 — Use unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 — Use observable inputs other than Level 1 prices such as quoted prices for identical or similar instruments in markets that are not active, quoted prices for similar instruments in active markets, and model-based valuation in which all significant inputs are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 — Use inputs that are generally unobservable and reflect the use of significant management judgments and estimates.

See Note 21, “Fair Value Measurement”, for the related disclosure.

Cash Equivalents

The Company considers all highly liquid instruments acquired with a remaining maturity of three months or less when purchased to be cash equivalents. In addition, time deposits with maturities ranging from more than three months to one year are qualified as cash equivalents as the nature of the time deposits are similar to cash such that without advance notice to the bank, they can be readily converted into known amounts of cash with the principal of the time deposits protected and not subject to penalty in the event of an early withdrawal. Also, the risk of changes in value because of changes in interest rates is insignificant due to the fact that the Company can still earn interest based on a rate close to the on-going published interest rate applicable for the actual period of the time deposits in the event of an early withdrawal. Cash and cash equivalents are stated at cost, which approximates their fair value.

Short-term Investments

The Company’s short-term investments primarily include short-term income yielding investments with original maturities greater than three months from the purchase date and remaining maturities less than one year.

 

F-9


Table of Contents

These short-term investments consist mostly of bond funds and principal protected notes that are bought and held principally for the purpose of selling them in the near term and are classified as trading securities as well as senior notes classified as held-to-maturity investments with maturities less than one year. Trading securities are reported at fair value with the subsequent changes in fair value recorded in earnings as unrealized gains and losses. Senior notes are measured at amortized cost using the effective interest method less any impairment.

Allowance for Doubtful Receivables

An allowance for doubtful receivables is provided based on a review of the collectability of accounts receivables. The Company determines the amount of allowance for doubtful receivables by examining the historical collection experience and current trends in the credit quality of its customers as well as its internal credit policies.

Inventories

Inventories are stated at the lower of cost or market value. Inventories are recorded at standard cost and adjusted to the approximate weighted-average cost at the balance sheet date. Market value represents the current replacement cost for raw materials, work in process and finished goods. The Company assesses its inventory for estimated obsolescence or unmarketable inventory based upon management’s assumptions about future demand and market conditions. In estimating reserves for obsolescence, the Company primarily evaluates estimates based on the timing of the introduction of new products and the quantities remaining of old products and provides reserves for inventory on hand in excess of the estimated demand. Estimated losses on slow-moving items are recognized and included in the allowance for losses.

Long-term Investments

Investee companies over which the Company had the ability to exercise significant influence but did not have a controlling interest and was the primary beneficiary were accounted for using the equity method. Significant influence was generally considered to exist when the Company had an ownership interest in the voting shares of the investee between 20% and 50%, and other factors, such as representation in the investee’s board of directors, voting rights and the impact of commercial arrangements, were considered in determining whether the equity method of accounting was appropriate. Under this method of accounting, the Company recorded its proportionate share of the net earnings or losses of equity method investees and a corresponding increase or decrease to the investment balances. The Company evaluated its equity method investments for impairment whenever events or changes in circumstances indicated that the carrying amounts of such investments might not be recoverable.

Prior to adopting ASU 2016-01 on January 1, 2018, the Company has long-term investments in companies that it does not exercise significant influence and accounts for these investments under the cost method. Management regularly evaluates financial information related to these investments to determine whether an other than temporary decline in their value exists. Factors indicative of an other than temporary decline include recurring operating losses, credit defaults and subsequent rounds of financings at an amount below the cost basis of the investment. Management periodically weighs all quantitative and qualitative factors in determining if any impairment loss exists. When a decline in value is deemed to be other-than-temporary, the Company recognizes an impairment loss in other income and expense. After adopting ASU 2016-01 on January 1, 2018, the Company elected to record equity investments without readily determinable fair values and not accounted for by the equity method at cost less impairment, adjusted for subsequent observable price changes whether there are observable price changes in orderly transactions for the identical or similar investment of the same issuer.

Noncurrent Assets Held for Sale

Non-current assets are presented separately as held for sale when the Company is committed to selling the asset, an active plan of sale has commenced, and the sale is expected to be completed within 12 months. Assets held for sale are measured at the lower of their carrying amount and fair value less cost to sell. Assets held for sale are no longer amortized or depreciated.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Significant additions, renewals and betterments are capitalized, while maintenance and repairs are expensed as incurred.

Depreciation is computed using the straight-line method over estimated useful lives that range as follows: buildings — 25 to 50 years; machinery and equipment — 3 to 6 years; furniture and fixtures — 3 to 8 years; software — 1 to 5 years; leasehold and buildings improvement — the shorter of the estimated useful life or lease term, which is generally 2 to 6 years. Land is not depreciated. Depreciation expense recognized for the years ended December 31, 2016, 2017 and 2018 was approximately US$9,482 thousand, US$10,599 thousand and US$11,832 thousand, respectively.

Upon the sale or other disposal of property and equipment, the related cost and accumulated depreciation are removed from the accounts, and any gain or loss is credited or charged to operating income.

Government Grants

Grants received by the Company from the Korean government to assist with specific research and development activities are deducted from those research and development costs incurred, in the period in which the related expenses are incurred, to the extent that they are non-refundable. Government grants that were used for the acquisition of fixed assets are deducted from the acquisition costs of the acquired assets and amortized over the useful lives of the related assets. The Company recognizes refundable government grants as long-term payable and current portion of long-term payable on its consolidated balance sheet.

Goodwill and Intangible Assets

Goodwill is the excess of the purchase price paid over the fair value of the net tangible and intangible assets acquired in a business combination. Intangible assets, which consist primarily of development technology, are amortized over their estimated useful lives, of 3.5 to 5.5 years.

Impairment of Goodwill and Long-Lived Assets

The Company evaluates the recoverability of long-lived assets whenever events or changes in circumstances indicate the carrying value may not be recoverable. The determination of recoverability is based on an estimate of undiscounted cash flows expected to result from the use of an asset and its eventual disposition. The estimate of cash flows is based upon, among other things, certain assumptions about expected future operating performance, growth rates and other factors. Estimates of undiscounted cash flows may differ from actual cash flows due to, among other things, technological changes, economic conditions, changes to the business model or changes in operating performance. If the sum of the undiscounted cash flows is less than the carrying value, an impairment loss is recognized, measured as the amount by which the carrying value exceeds the fair value of the asset. Fair value is determined by reference to quoted market prices, if available, or discounted cash flows, as appropriate. See Note 11, “Goodwill and Acquired Intangible Assets,” regarding impairment testing in fiscal year 2016, 2017 and 2018.

The Company monitors the recoverability of goodwill recorded in connection with acquisitions, by reporting unit, annually, or sooner if events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company conducts its annual impairment test of goodwill on November 30. Reporting units may be operating segments as a whole or an operation one level below an operating segment, referred to as a component. Prior to fiscal 2017, goodwill impairment is tested using a two-step approach. The first step compares the fair value of a reporting unit to its carrying amount, including goodwill. If the fair value of the reporting unit is greater than its carrying amount, goodwill is not considered impaired and the second step is not required. If the fair value of the reporting unit is less than its carrying amount, the second step of the impairment

 

F-11


Table of Contents

test measures the amount of the impairment loss, if any, by comparing the implied fair value of goodwill to its carrying amount. If the carrying amount of goodwill exceeds its implied fair value, an impairment loss is recognized equal to that excess. The implied fair value of goodwill is calculated in the same manner that goodwill is calculated in a business combination, whereby the fair value of the reporting unit is allocated to all of the assets and liabilities of that unit, with the excess purchases price over the amounts assigned to assets and liabilities.

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2017-04, which removes step two from the goodwill impairment test. The Company elected to early adopt this ASU in the fourth quarter of 2017, in conjunction with the Company’s annual review for impairment.

Estimating fair value is performed by utilizing various valuation approaches, such as income approach or market approach. The total of all reporting unit fair values is also compared to the Company’s market capitalization plus control premium for reasonableness. See Note 11, “Goodwill and Acquired Intangible Assets,” regarding impairment testing.

Other Assets

Other assets primarily consist of industrial property right and deposits for office leases.

Restricted Assets

Restricted assets consist of restricted cash. Restricted cash represents cash set aside as collateral for obtaining capacity and borrowings as well as cash received from government grants with restriction on its usage.

Bank loans

Revolver credit from financial institutions are stated at the amount of unpaid principal.

Other long-term liabilities

Other long-term liabilities primarily consist of payables to former shareholders of Shannon Systems and unrecognized tax benefits.

Pension Costs

For employees under defined contribution pension plans, pension costs are recorded based on the actual contributions made to employees’ individual pension accounts. For employees under defined benefit pension plans, pension costs are recorded based on actuarial calculations.

Revenue Recognition

Through the fiscal year ended December 31, 2017, revenue from product sales was generally recognized upon shipment to the customer provided that the Company had received a signed purchase order, the price was fixed or determinable, transfer of title had occurred in accordance with the shipping terms specified in the arrangement with the customer, collectability from the customer was considered reasonably assured, product returns were reasonably estimable and there were no remaining significant obligations or customer acceptance requirements. Revenue on development service orders was generally recognized upon completion and customer acceptance of contractually agreed milestones.

As a result of the adoption of the new revenue standard (ASC 606) on January 1, 2018, using the modified retrospective method with the cumulative effect of initially applying it recognized at the date of initial

application, the Company revised its revenue recognition policy. The Company now recognizes revenue upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Under the new revenue recognition standard, the Company applies the following five step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.

The Company enters into contracts that may include products that are capable of being distinct and accounted for as separate performance obligations. To date, the majority of the revenue has been generated by sales associated with products of storage and mobile communication, where a single performance obligation is identified in general. Revenue from services has been insignificant. Performance obligations associated with product sales transactions are generally satisfied when control passes to customers upon shipment or the written acceptance of the customers. Accordingly, product revenue is recognized at a point in time when control of the asset is transferred to the customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control of a product to a customer in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods. Some of the Company’s sales are made to distributors. Control passes to the distributor upon shipment, and terms and payment by the Company’s distributors is not contingent on resale of the product.

The Company grants certain distributors limited rights of return and price protection rights on unsold products. The return rights are generally limited to five percent of the monetary value of products purchased within the preceding six months, provided that the distributor places a corresponding restocking order of equal or greater value. An allowance for sales returns for distributors and all customers is recorded at the time of sale based on historical returns information available, management’s judgment and any known factors at the time the financial statements are prepared that would significantly affect the allowance. Price protection rights are based on the inventory products the distributors have on hand at the date the price protection is offered. The actual price adjustments to distributors incurred by the Company are minimal.

The Company provides a standard one-year warranty for manufacturing defects of its products. Warranty returns have been infrequent and relate to defective or off-specification parts. The Company estimates a reserve for warranty based on historical experience and records this amount to cost of sales. For the years ended December 31, 2016, 2017 and 2018, the Company did not experience significant costs associated with warranty returns.

Prior to the application of ASC 606, the Company recognized the estimation of sales returns and allowance as a credit to accounts receivables. Under ASC 606, the Company recognizes such estimation as refund liability.

Research and Development

Research and development costs consist of expenditures incurred during the course of planned research and investigation aimed at the discovery of new knowledge that will be useful in developing new products or at

significantly enhancing existing products as well as expenditures incurred for the design and testing of product alternatives. All expenditures related to research and development activities of the Company are charged to operating expenses when incurred. Third-party research and development costs are expensed when the contracted work has been performed or as milestone results have been achieved.

Income Taxes

The provision for income tax represents income tax paid and payable for the current year plus changes in the deferred income tax assets and liabilities during the years. Deferred income tax assets are recognized for net operating loss carryforwards, research and development credits, and temporary differences. The Company believes that uncertainty exists regarding the realizability of certain deferred income tax assets and, accordingly, has established a valuation allowance for those deferred income tax assets to the extent the realizability is not deemed to be more likely than not. Deferred income tax assets and liabilities are measured using enacted tax rates.

The Company utilizes a two step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained in a dispute with taxing authorities, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest and penalties related to unrecognized tax benefits in income tax expense.

Foreign Currency Transactions

Foreign currency transactions are recorded at the rates of exchange in effect when the transaction occurs. Gains or losses, resulting from the application of different foreign exchange rates when cash in foreign currency is converted into the entities’ functional currency, or when foreign currency receivables and payables are settled, are credited or charged to income in the period of conversion or settlement. At the balance sheet date, assets and liabilities denominated in foreign currencies are remeasured based on prevailing exchange rates and any resulting gains or losses are credited or charged to income.

Translation of Foreign Currency Financial Statements

The reporting currency of the Company is the U.S. dollars. The functional currency of some of the Company’s subsidiaries is the local currency of the respective entity. Accordingly, the financial statements of the foreign subsidiaries were translated into U.S. dollars at the following exchange rates: assets and liabilities — current rate on the balance sheet date; shareholders’ equity — historical rates; income and expenses — average rate during the period. The resulting translation adjustment is recorded as a separate component of comprehensive income.

Legal Contingencies

The Company is regularly involved in various claims and legal proceedings. Periodically, the Company reviews the status of each significant matter and assesses the potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, the Company accrues a liability for the estimated loss. Because of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, the Company reassesses the potential liability related to the pending claims and litigation and revises these estimates as appropriate. Such revisions in the estimates of the potential liabilities could have a material impact on the results of operations and financial position.

Earnings Per Share

Basic earnings per share are computed by dividing net earnings attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. Diluted earnings per share reflect the potential dilution that could occur if stock options and other dilutive securities were exercised. Dilutive securities are excluded from the computation of the diluted income per share in periods when their effect is anti-dilutive. The Company’s dilutive securities consist of employee stock options and restricted stock units. The effect of dilutive securities including employee stock options and restricted stock units were 1,131 thousand shares (283 thousand ADSs), 868 thousand shares (218 thousand ADSs) and 389 thousand shares (97 thousand ADSs) for the years ended December 31, 2016, 2017 and 2018, respectively.

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718 Compensation — Stock Compensation. The Company uses the Black-Scholes valuation model for the valuation of stock options and recognizes compensation expense on a straight-line basis over the requisite service period of the award. The value of our restricted stock units is based on the fair value of our shares on the date of grant and expensed over the vesting period.

Prior to the initial declaration of a quarterly cash dividend on January 22, 2013, the fair value of restricted stock units (“RSUs”) was measured based on the grant date share price, as the Company did not historically pay cash dividends on our common stock. For awards granted on or subsequent to January 22, 2013, the fair value of RSUs was measured based on the grant date share price, less the present value of expected dividends during the vesting period, discounted at a risk-free interest rate.

Treasury Stock

Treasury stock is stated at cost and shown as a reduction to shareholders’ equity. A repurchase of ADSs is recorded as treasury stock until the Company completes the withdrawal of the underlying ordinary shares from the ADS program.

Dividends

The board of directors declared payment of our first quarterly dividend on our common stock in January 2013 and the first dividend payment was made on March 4, 2013. The board of directors has subsequently declared and paid dividends in each successive quarter. Beginning on November 2, 2015, the board of directors, instead of declaring a quarterly dividend, declared an annual dividend payable in four quarterly installments. The payment of future cash dividends are subject to the Board’s continuing determination that the payment of dividends are in the best interests of the Company’s shareholders and are in compliance with all laws and agreements of the Company applicable to the declaration and payment of cash dividends.

Recent Accounting Pronouncements

In May 2014, the FASB issued a new standard related to revenue recognition. Under the new standard, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the new standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued an amendment to defer the effective date. The new standard is effective for fiscal years beginning after December 15, 2017 and early adoption is permitted for annual reporting periods beginning after December 15, 2016. In March and April 2016, the FASB issued two accounting updates to clarify the implementation guidance on principal versus agent considerations, performance obligations and licensing. In addition, the FASB issued another accounting update in May 2016 to address narrow-scope improvements to the guidance on collectability, noncash consideration, and completed contracts at transition and provides a practical expedient for contract modifications at transition. The new guidance is required to be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application. The Company adopted this new standard using the modified retrospective method with the cumulative effect of initially applying it recognized at the date of initial application. The adoption of this new standard did not have a material impact on the Company’s financial position, results of operations, cash flow and financial statement disclosures.

In January 2016, the FASB issued an accounting update regarding the subsequent measurement of equity investment. The amendment requires all equity investment to be measured at fair value with changes in the fair value recognized through net income other than those accounted for under equity method of accounting or those that result in consolidation of the investee. The amendment also simplifies the impairment assessment of equity investments without readily determinable fair value by requiring assessment for impairment qualitatively and eliminating the complexity of the other-than-temporary impairment guidance. For financial reporting, the amendment requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendment eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. In February 2018, the FASB issued an accounting update to further clarify certain aspects of the guidance in the recognition and the measurement of financial assets and financial liabilities. The amendments are effective for fiscal years beginning after December 15, 2017 and early application is prohibited. The adoption of this amendment did not have a material impact on the Company’s financial position, results of operations, cash flow and financial statement disclosures.

In February 2016, the FASB issued a new standard regarding leases (Topic 842). The new standard requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases other than

 

F-16


Table of Contents

that the entity elects the short-term lease recognition and measurement exemption. Qualitative and quantitative disclosures will be enhanced to better understand the amount, timing and uncertainty of cash flows arising from leases. In January 2018, the FASB issued an amendment permits an entity to elect an optional transition practical expedient to not evaluate under Topic 842 land easements that exist or expired before the entity’s adoption of Topic 842 and that were not previously accounted for as leases under Topic 840, the current standard regarding leases. In July 2018, the FASB issued two amendments to (1) clarify how to apply certain aspects of the new leases standard addressing the rate implicit in the lease, lessee reassessment of lease classification, lessor reassessment of lease term and purchase options, among other issues; (2) provide an optional transition method that allows the entity to initially apply the new lease requirements by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without restating prior periods; and (3) provide an practical expedients that lease and associated non-lease components are not required to be separated within lessor arrangements if certain criteria are met. In addition, in December 2018, the FASB issued another accounting update regarding lease to clarify guidance for lessors on sales taxes and other similar taxes collected from lessees, certain lessor costs and recognition of variable payments for contracts with lease and non-lease components. The standard is effective for the Company beginning on January 1, 2019. The Company is adopting the new lease accounting standard using a modified retrospective method and will not restate comparative periods. The Company expects that the adoption of the new leasing standard will result in recognition of US$7,886 thousand in lease related right-of-use assets and liabilities on the Company’s consolidated balance sheet, primarily related to office buildings.

In June 2016, the FASB issued an accounting update to amend the guidance on the impairment of financial instruments that are not measured at fair value through profit and loss. The amendment introduces a current expected credit loss (CECL) model based on expected losses rather than incurred losses to estimate credit losses on financial instruments measured at amortized cost and requires a broader range of reasonable and supportable information to estimate expected credit loss. In addition, under the amendment, an entity recognizes an allowance for expected credit losses on financial instruments measured at amortized cost and available-for-sale debt securities rather than the current methodology of delaying recognition of credit losses until it is probable a loss has been incurred. In November 2018, the FASB issued an accounting update to clarify that receivables arising from operating leases are not within the scope of new credit losses guidance. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. The amendment is effective for fiscal years beginning after December 15, 2019, and earlier adoption is permitted as of the fiscal years beginning after December 15, 2018. The adoption of the amendments is not expected to have a material impact on the Company’s statement of cash flows.

In August 2016, the FASB issued an accounting update to clarify the following eight cash flow classification issues: (1) debt prepayment or debt extinguishment costs, (2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, (3) contingent consideration payments made after the acquisition date of a business combination, (4) proceeds received from the settlement of insurance claims, (5) proceeds received from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (6) distributions received from equity method investees, (7) beneficial interests in securitization transactions, and (8) separately identifiable cash flows and application of the predominance principle. The amendment is an improvement to reduce the current and potential future diversity in practice. The amendment is effective for fiscal years beginning after December 15, 2017, and earlier adoption is permitted. In addition, the amendment should be applied using a retrospective transition method to each period presented. The adoption of the amendments did not have a material impact on the Company’s statement of cash flows.

In October 2016, the FASB issued an accounting update to simplify the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The amendment removes the prohibition against the recognition of current and deferred income tax effects of intra-entity transfers of assets other than inventory until the asset has been sold to an outside party. The amendment is effective for fiscal years beginning after December 15, 2017, and earlier adoption is permitted. The adoption of this amendment did not have a

material impact on the Company’s financial position, results of operations, cash flow and financial statement disclosures.

In November 2016, the FASB issued an accounting update related to the classification and presentation of changes in restricted cash on the statement of cash flows. The amendment requires restricted cash or restricted cash equivalents should be included with cash and cash equivalent when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendment is effective for fiscal years beginning after December 15, 2017, and early adoption is permitted. The Company has elected to adopt the amendment as of December 31, 2016, and the retrospective transition approach is applied to prior reporting periods presented.

In January 2017, the FASB issued an accounting update to clarify the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendment provides a screen to determine when an integrated set of assets and activities (collectively referred to as a “set”) is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, the amendment requires that to be considered a business, a set must include an input and a substantive process that together significantly contribute to the ability to create output. The amendment is effective for fiscal years beginning after December 15, 2017. The adoption of this amendment did not have a material impact on the Company’s financial position, results of operations, cash flow and financial statement disclosures.

In January 2017, the FASB issued an accounting update to simplify the accounting treatment for the impairment of goodwill. The amendment eliminates Step 2 from the goodwill impairment test, which measures a goodwill impairment loss by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Instead, under this amendment, the entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value and the impairment loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendment is effective for fiscal years beginning after December 15, 2019, and early adoption is permitted. The Company adopted this amendment beginning in fiscal 2017 and performed the annual goodwill impairment test in accordance with the amended guidance. Refer to Note 11 for discussion of the annual goodwill impairment test.

In February 2017, the FASB issued an accounting update to clarify the scope of asset derecognition guidance and accounting for partial sales of nonfinancial assets. The amendment defines the term “in substance nonfinancial asset” as a financial asset promised to counterparty in a contract if substantially all of the fair value of assets (recognized and unrecognized) that are promised to the counterparty in the contract is concentrated in nonfinancial assets and clarifies that an entity should identify each distinct nonfinancial asset or in substance nonfinancial asset promised to a counterparty and derecognize each asset when a counterparty obtains control of it. The amendment also clarifies that an entity should allocate consideration to each distinct asset by applying the guidance in Topic 606 on allocating the transaction price to performance obligations. Under this amendment, an entity is required to derecognize a distinct nonfinancial asset or distinct in substance nonfinancial asset in a partial sale transaction when it (1) does not have (or ceases to have) a controlling financial interest in the legal entity that holds the asset in accordance with Topic 810 and (2) transfers control of the asset in accordance with Topic 606. Once an entity transfers control of a distinct nonfinancial asset or distinct in substance nonfinancial asset, it is required to measure any noncontrolling interest it receives (or retains) at fair value. The amendment is effective for fiscal years beginning after December 15, 2017 and early adoption is permitted. The amendment should be applied on a full or modified retrospective basis. The adoption of this amendment did not have a material impact on the Company’s financial position, results of operations, cash flow and financial statement disclosures.

In March 2017, the FASB issued an accounting update to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The amendment requires that an entity disaggregates the service

 

F-18


Table of Contents

cost component from the other components of net benefit cost and present the service cost component with other current compensation costs for related employees in the income statement. The amendment also requires an entity presents the other components elsewhere in the income statement and outside of income from operation if such subtotal is presented and allow only the service cost component of net benefit cost to be eligible for capitalization. The amendment is effective for fiscal years beginning after December 15, 2017 and early adoption is permitted. The amendment should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. The amendment allows for a practical expedient that permits an entity to use the amounts disclosed in its pension and other postretirement benefit plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. The Company intends not to apply the practical expedient for retrospective presentation requirements. The adoption of this amendment did not have a material impact on the Company’s financial position, results of operations, cash flow and financial statement disclosures.

In May 2017, the FASB issued an accounting update to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation — Stock Compensation, to a change in the terms or conditions of a share-based payment award. Under the amendment, modification accounting is required to be applied unless all of the following are the same immediately before and after the change: (1) the award’s fair value (or calculated value or intrinsic value, if those measurement methods are used); (2) the award’s vesting conditions; and (3) the award’s classification as an equity or liability instrument. The amendment is effective for fiscal years beginning after December 15, 2017 and early adoption is permitted. The amendment should be applied prospectively to an award modified on or after the adoption date. The adoption of this amendment did not have a material impact on the Company’s financial position, results of operations, cash flow and financial statement disclosures.

In August 2018, the FASB issued an accounting update to amend fair value measurement disclosure requirements to eliminate, add and modify certain disclosures to improve the effectiveness of such disclosure. The amendments removed (1) the disclosure requirements for transfers between Levels 1 and 2 of the fair value hierarchy, (2) the policy for timing of transfers between levels of the fair value hierarchy; and (3) the valuation processes for Level 3 fair value measurements. Additionally, the amendments modified the disclosure requirements for investments in certain entities that calculate net asset value and measurement uncertainty. Finally, the amendments added disclosure requirements for the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 measurements. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. This amendment is effective for annual periods beginning after December 15, 2019. Early adoption is permitted. The adoption of this amendment is not expected to have a material impact on the Company’s financial position, results of operations, cash flow and financial statement disclosures.

In August 2018, the FASB issued an accounting update to modify disclosure requirements by removing, modifying and clarifying disclosures related to defined benefit plans. This amendment modified the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Certain disclosure requirements have been removed while the disclosure requirements of (1) the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates; and (2) an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period, have been added. The amendment also clarified the disclosure requirements with respect to the projected benefit obligation and the accumulated benefit obligation. The amendment is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The amendments should be applied on a retrospective basis to all periods

3. BUSINESS ACQUISITION

Bigtera

On July 3, 2017, the Company completed its acquisition of Bigtera, a software defined storage company. In exchange for 100% of the outstanding shares of common stock of Bigtera, the Company paid approximately US$4,664 thousand in cash. In 2017, the Company incurred US$171 thousand of acquisition costs which comprised primarily of transaction fees and direct acquisition costs, including legal and other professional fees. These costs are included in the line item of “operating expenses — general and administrative” on the consolidated statements of income.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition:

As of December 31, 2018, approximately US$1,099 thousand has not been paid to the former shareholders of Bigtera and is included in other current liabilities on the consolidated balance sheets as of December 31, 2018.

The excess of the purchase price over the fair value of the net tangible assets acquired has been reflected as identifiable intangible assets. The identifiable intangible assets and respective useful lives are as follows:

 

     US$      Useful Life  

Know-how

     3,753        5.5  

Current technology

     983        5.5  
  

 

 

    

Total identifiable intangible assets

     4,736     
  

 

 

    

Know-how represents software defined storage technology that has value through its continued use or reuse across all version of Bigtera’s software products. Such know-how derives independent value from not being generally known and is the subject of efforts that are reasonable under the circumstances to maintain its secrecy.

Current technology represents the part of technology that is unique in current version of software products.

Goodwill represents the excess of the purchase price over the estimated fair values of the net tangible and intangible assets. The factors that contributed to the recognition of goodwill primarily relate to expansion into new product areas and potential synergies created from combined capabilities, and goodwill is not expected to be deductible for tax purposes.

The Company assesses the impairment of intangible assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. No impairment losses were recognized in 2016 and 2017. In 2018, the Company determined that the carrying amounts for intangible assets of its Bigtera unit exceeded its fair value, which was close to nil, and recorded impairment charges of US$3,444 thousand due to lower than projected revenue. The impairment was measured based on a projected discounted cash flow method. Certain factors, such as revenue growth rates, projected gross margins, perpetual growth rate and risk-adjusted discount rate used for this nonrecurring fair value measurement were considered Level 3 within the fair value hierarchy due to the significance of unobservable inputs using company specific information. Amortization expense of acquisition-related intangible assets for the years ended December 31, 2016, 2017 and 2018 were US$2,103 thousand, US$2,534 thousand and US$2,964 thousand, respectively.

Goodwill: Goodwill is not amortized, but instead is reviewed and tested for impairment at least annually or whenever events or circumstances occur which indicate that goodwill might be impaired. The goodwill that resulted from the Company’s acquisition of FCI and Centronix in 2007 and purchase of BTL’s assets in 2011 was US$66,300 thousand. As a result of the acquisition of Shannon Systems in 2015 and Bigtera in 2017, the Company recorded additional goodwill of US$33,204 thousand and US$625 thousand, respectively. Impairment of goodwill is tested at the Company’s reporting unit level by comparing the carrying amount, including goodwill, to the fair value. In performing the analysis, the Company uses the best information available, including reasonable and supportable assumptions and projections. Goodwill is tested for impairment annually on November 30. Total goodwill was US$58,964 thousand and US$58,331 thousand as of December 31, 2017 and 2018, respectively. The Company recognizes an impairment charge for the amount by which the carrying amount of the reporting unit exceeds its implied fair value.

The Company elected to adopt ASU 2017-04 starting 2017 (as described in Note 2 above). Under the updated guidance, the Company applied a one-step quantitative test and recorded the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value. Fair value determinations are sensitive to changes in the underlying assumptions and factors including those relating to estimating future operating cash flows to be generated from the reporting unit which are dependent upon historical data and internal forecasts and projections developed by management. The Company’s strategic plans, estimates of perpetual growth rate taking into account the annual goodwill impairment analysis of the current economic environment and the timing and degree of any economic recovery and market participant assumptions. Key assumptions within the five-year discounted cash flow analysis prepared for the annual goodwill impairment analysis included revenue growth rates, projected gross margins, perpetual growth rate and risk-adjusted discount rate that the Company determined to be appropriate. The inputs used are classified as Level 3 within the fair value hierarchy due to the significance of unobservable inputs using company-specific information. As a result of the goodwill impairment tests conducted as of November 30, 2017 and 2018, the Company determined that the carrying amounts for mobile communications unit and Bigtera unit exceeded the fair value and recorded goodwill impairment charges of US$10,337 thousand and US$625 thousand in the fourth quarter of 2017 and 2018, respectively. The company used an income approach (discounted cash flow model) to determine the fair value of the mobile communications unit and the Bigtera unit. Mobile communications unit impairment charge in 2017 was mainly attributable to a project cancellation by a customer and delayed commercialization of a new product. Bigtera unit impairment charge in 2018 was mainly due was to lower than projected revenue.

15. PENSION PLAN

SMI Taiwan, the Company’s largest operating company is a Taiwan registered company and subject to Taiwan’s Labor Pension Act (the “Act”), which became effective on July 1, 2005, and the pension mechanism under the Act is deemed a defined contribution plan. The employees who were subject to the Labor Standards Law prior to July 1, 2005 could choose to be subject to the pension mechanism under the Act or continue to be subject to the pension mechanism under the Labor Standards Law. For those employees who were subject to the Labor Standards Law prior to July 1, 2005 and still work for the same company after July 1, 2005 and have chosen to be subject to the pension mechanism under the Act, their seniority as of July 1, 2005 were maintained. The Act prescribes that the rate of contribution by an employer to employees’ pension accounts per month will not be less than 6% of each employee’s monthly salary. According to the Act, SMI Taiwan made monthly contributions and recognized pension costs of US$1,272 thousand, US$1,579 thousand and US$1,682 thousand for the years ended December 31, 2016, 2017 and 2018, respectively.

Table of Contents

The Company provides a defined benefit plan to the employees of SMI Taiwan under the Labor Standards Law that offers benefits based on an employee’s length of service and average monthly salary for the six-month period prior to retirement. The Company contributes an amount equal to 2% of salaries paid each month to a pension funds (the “Funds”), which is administered by the Labor Pension Fund Supervisory Committee established by the government (the “Committee”) and deposited in the Committee’s name in the Bank of Taiwan. Before the end of each year, the Company assesses the balance in the Funds. If the amount of the balance in the Funds is inadequate to pay retirement benefit for employees who conform to retirements requirements in the next year, the Company is required to fund the difference in one appropriation that should be made before the end of March of the next year. The government is responsible for administering the defined benefit plans of the companies in Taiwan under the Labor Standards Law. The government also sets investment policies and strategies, determines investment allocation and selects investment managers. As of December 31, 2017 and 2018, the asset allocation was primarily in cash, equity securities and debt securities. Furthermore, under the Labor Standards Law, the rate of return on assets shall not be less than the average interest rate on a two-year time deposit published by the local banks. The government is responsible for any shortfall in the event that the rate of return is less than the required rate of return. However, information on how investment allocation decisions are made, inputs and valuation techniques used to measure the fair value of plan assets, the effect of fair value measurements using significant unobservable inputs on changes in plan assets for the period and significant concentrations of risk within plan assets is not fully made available to the Company by the government. Therefore, the Company is unable to provide the required fair value disclosures related to pension plan assets. Future contributions will be based on 2% of the employee salaries at that time. The Company estimates its contribution for the year ending December 31, 2019 to be US$67 thousand which was determined based on 2% of estimated salaries in 2019.

Starting in 2010, the Company provides a defined benefit pension plan to employees of FCI in Korea with at least one year of service. FCI’s overall investment strategy is to avoid a loss on plan assets. FCI estimates its contribution for the year ending December 31, 2019 to be nil.

For employees under defined contribution pension plans, pension costs are recorded based on the actual contributions made to employees’ individual pension accounts. For employees under defined benefit pension plans, pension costs are recorded based on actuarial calculations. Determining the cost associated with such benefits is dependent on various actuarial assumptions, including discount rate, expected return on plan assets, compensation increase, employee mortality and turnover rates. The Company reviewed its actuarial assumptions at the measurement date on December 31 every year. The effect of modifications to assumptions is recorded in accumulated other comprehensive loss and amortized to net periodic cost over future periods using the corridor method. The Company believes that assumptions utilized in recording its obligations under its plans are reasonable based on its experience and market conditions. Independent actuaries perform the required calculations to determine expense in accordance with U.S. GAAP. Actual results may differ from the actuarial assumptions and are generally accumulated and amortized into earnings over future periods. The net periodic costs are recognized as employees render the services necessary to earn the benefits.

Since the Company is an entity of the Cayman Islands, a British overseas territory with no corporate income tax, tax on pretax income is calculated at the Cayman Islands statutory rate of zero for each year.

The Company and its subsidiaries file separate income tax returns. A reconciliation of income tax expense on pretax income at statutory rate and income tax expense is shown below:

The valuation allowance shown in the table above relates to net operating loss carryforwards, tax credits and temporary differences for which the Company believes that realization is uncertain. Valuation allowance increased by US$1,792 thousand and US$969 thousand for the year ended December 31, 2016 and 2018, respectively, and decreased by US$1,764 thousand for the year ended December 31, 2017. The increase in valuation allowance in 2016 and 2018 are primarily due to the uncertainty in generating sufficient taxable income in the future and utilization of operating loss carryforwards and research and development credits before they expire. The decrease in valuation allowance in 2017 was primarily due to the lower Federal corporate income tax rate that followed the enactment of the Tax Cuts and Jobs Act of 2017.

Starting from 2018 the corporate income tax rate in Taiwan increased from 17% to 20%. In addition, the rate of the corporate surtax applicable to 2018 unappropriated earnings was reduced from 10% to 5%.

As of December 31, 2018, FCI had unused research and development tax credits of approximately US$4,069 thousand which will expire in the period from 2019 to 2023.

As of December 31, 2018, the Company’s U.S. federal net operating loss carryforwards for federal income tax purposes were approximately US$8,574 thousand. If not utilized, the federal net operating loss carryforwards will expire in 2038.

As of December 31, 2018, the Company’s U.S. federal and California research and development tax credit carryforwards for federal and state income tax purposes were approximately US$2,636 thousand and US$1,834 thousand, respectively. If not utilized, the federal tax credit carryforwards will expire starting in 2038 while the state tax credit carryforward has no expiration date.

Current U.S. federal and California state laws include substantial restrictions on the utilization of net operating losses and credits in the event of an “ownership change” of a corporation. Accordingly, the Company’s ability to utilize net operating loss and tax credit carryforwards may be limited as a result of such “ownership change”. Such a limitation could result in the expiration of carryforwards before they are utilized.

As of December 31, 2018, the Company had accumulated undistributed earnings from foreign subsidiaries of US$337 million. No deferred tax liability was recorded in respect of those amounts as these earnings are considered indefinitely reinvested. It is not practicable to estimate the amount of unrecognized deferred tax liabilities for these undistributed foreign earnings.

At December 31, 2018, the Company had US$18,707 thousand of unrecognized tax benefits that if recognized would affect the effective tax rate. For the years ended December 31, 2016, 2017 and 2018, the total amount of interest expense and penalties related to uncertain tax positions recorded in the provision for income tax expense was approximately US$575 thousand, US$617 thousand and US$776 thousand, respectively. The total amount of accrued interest and penalties recognized as of December 31, 2017 and 2018 was US$3,421 thousand and US$4,091 thousand, respectively. The Company does not expect uncertain tax positions to change in the next twelve months, except in the case of settlements with tax authorities, the likelihood and timing of which are difficult to estimate.

The Company files income tax returns in United States and foreign jurisdictions. The following table summarizes the Company’s major jurisdictions and tax year that remain subject to examination by tax authorities as of December 31, 2018:

2018, respectively. Future dividends, if any, will be declared by and subject to the discretion of the Company’s board of directors. If the Company’s board of directors decides to distribute dividends, the form, frequency and amount of such dividends will depend upon the Company’s future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors the board of directors may deem relevant.

Any future dividend the Company declares will be paid to the holders of ADSs, subject to the terms of the depositary agreement, to the same extent as holders of the Company’s ordinary shares, to the extent permitted by applicable laws and regulations, less the fees and expenses payable under the deposit agreement. Any dividend the Company declares will be distributed by the depositary bank to the holders of our ADSs. Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.

Treasury Stock

On November 21, 2018, the board of directors of the Company approved share buyback plans to repurchase up to US$200 million of the Company’s ADSs over a 24 month period. The program did not obligate the Company to acquire any particular amount of ADS and the program may be modified or suspended at any time at the Company’s discretion. As of December 31, 2018, the Company repurchased 1,006 thousand ADSs for a total cost of US$34.8 million. The weighted average purchase price per ADS repurchased was US$34.54.

18. EQUITY INCENTIVE PLAN

2005 Equity Incentive Plan and 2015 Equity Incentive Plan

On April 22, 2005, the Company adopted its 2005 Equity Incentive Plan (“the 2005 Plan”). The 2005 Plan provides for the grant of stock options, stock bonuses, restricted stock awards, restricted stock units and stock appreciation rights, which may be granted to employees (including officers), directors and consultants. The 2005 Plan reserved 10,000 thousand shares of ordinary shares, inclusive of the number of assumed share options under the 2004 Plan, for issuance upon the exercise of stock options.

In 2006, the Company amended the 2005 Plan to reserve an additional 15,000 thousand ordinary shares for issuance upon exercise of stock options and restricted stock units. In 2009, the Company amended the Plan to reserve an additional 15,000 thousand ordinary shares for issuance upon exercise of stock options and restricted stock units.

Restricted stock units are converted into shares of the Company’s ordinary shares upon vesting on one-for-one basis. The vesting of restricted stock unit is subject to the employee’s continuing service to the Company. The cost of these awards is determined using the fair value of the Company’s ordinary share on the date of the grant, and compensation is recognized on a straight-line basis over the requisite service period. The Company’s restricted stock units are considered non-vested share awards as defined under ASC 718.

In April 2010, the Company’s Board of Directors and Compensation Committee approved an employee stock option exchange program that required certain employees to exchange eligible stock options for a lesser number of new stock options that have approximately the same fair values as the options surrendered. Eligible options included stock options granted between August 17, 2005 and July 31, 2008 that had an exercised price above US$1.85. In 2010, 4,369 thousand eligible stock options were exchanged for 3,785 thousand new stock options granted. The new stock options have an exercise price of US$1.47, which was equal to the market price of the Company’s ordinary share on April 26, 2010, the date eligible stock options were surrendered and new stock options granted. The new stock options were issued under the 2005 Plan and are subject to its terms and conditions. The new stock options will continue to vest according to the original vesting schedule. Using the Black-Scholes option pricing model, the Company determined that the fair value of the surrendered stock options on a grant-by-grant basis was approximately equal, as of the date of the exchange, to the fair value of the new stock options granted, resulting in insignificant incremental share-based compensation.

On June 3, 2015, the Company adopted its 2015 Equity Incentive Plan (“the 2015 Plan”). The 2015 Plan provides for the grant of stock options, stock bonuses, restricted stock awards, restricted stock units and stock appreciation rights, which may be granted to employees (including officers), directors and consultants. The 2015 Plan reserved 20,000 thousand shares of ordinary shares for issuance upon exercise of stock options and restricted stock units.

FCI provided their employees with collateral for personal loans which is deposited at a designated bank and the amount deposited was US$468 thousand and US$448 thousand at December 31, 2017 and 2018, respectively. Such amounts were accounted for as restricted cash.

Operating Leases

The Company entered into various operating lease agreements for office space that expire on various dates through March 2022. The Company recognized rent expense for the years ended December 31, 2016, 2017 and 2018 of US$2,595 thousand, US$3,131 thousand and US$3,933 thousand, respectively. The minimum operating lease payments expected under these leases as of December 31, 2018 were US$2,802 thousand, US$1,757 thousand, US$1,263 thousand, US$65 thousand, and nil for the years ending December 31, 2019, 2020, 2021, 2022 and 2023, respectively.

Litigation

The Company is subject to legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business. Although the outcome of such proceedings and claims cannot be predicted with certainty, management does not believe that the outcome of any of these matters will have a material adverse effect on our business, results of operations, financial position or cash flows. Any litigation, however, involves potential risk and potentially significant litigation costs, and therefore there can be no assurance that any litigation which is now pending or which may arise in the future would not have such a material adverse effect on our business, financial position, results of operations or cash flows.

All American Semiconductor, Inc. (“All American” or “AASI”) was a former distributor for the Company. On April 25, 2007, All American filed for Chapter 11 bankruptcy protection. At the time of the filing, the Company had US$256 thousand of unpaid accounts receivable from All American. On April 17, 2009 SMI USA and related entities were named as defendants in an adversary proceeding filed by the AASI Creditor Liquidating Trust (“CLT”) in the bankruptcy case pending in the U.S. Bankruptcy Court for the Southern District of Florida. The CLT was seeking the return of allegedly avoidable transfers in the amount of US$854 thousand. SMI USA filed an answer and affirmative defenses. In March 2010, SMI USA settled with the CLT by paying the amount of US$220 thousand and on April 1, 2010, the Bankruptcy Court granted the motion to approve stipulations to compromise controversy. On August 23, 2010, the Court entered an order dismissing the adversary proceeding. In June 2011, Liquidating Trustee for the CLT filed the AASI Creditor Liquidating Trustee’s Seventeenth Omnibus Objection to Claims but in August 2011, withdrew it with respect to SMI USA’s proof of claim. As a holder of allowed claims, we are entitled to receive distribution pursuant to the bankruptcy plan. On December 31, 2017, we received total distributions of US$265 thousand from the CLT and this case is officially closed.

21. FAIR VALUE MEASUREMENT

The following section describes the valuation methodologies the Company uses to measure assets and liabilities at fair value.

 

F-37


Table of Contents

The Company uses quoted prices in active markets for identical assets to determine fair value where applicable. This pricing methodology applies to Level 1 investments such as bond funds. The fair value of the principal protected notes was determined by its present value utilizing rate of return as the market observable input and therefore, these are classified as Level 2 instruments. This is because there generally are no quoted prices in active markets for identical principal protected notes at the reporting date. Hence, in order to determine the fair value, the Company must use observable inputs other than quoted prices in active markets for identical or similar instruments, quoted prices for similar instruments in active markets, or other inputs that are observable.

For the years ended December 31, 2017 and 2018, none of the Company’s assets measured on a recurring basis was determined by using significant unobservable inputs.

The following table presents our assets measured at fair value on a recurring basis as of December 31, 2017 and 2018:

22. RELATED PARTY TRANSACTIONS

Lease support arrangements, known in Korea as Jeonse, were in place for certain Korean employees, primarily executive officers. These arrangements, in place from 2007 to 2019, consisted of a program which the Company facilitated housing arrangements by depositing funds with lessors who are either third parties, employees or relatives of the employees. Such funds would serve to establish the leasehold interest for the employees. When such arrangements are finished, the Company receives the deposited funds back in full. The deposited amount of these arrangements for such employees was US$1.6 million and US$1.5 million as of December 31, 2017 and 2018, respectively.

23. SUBSEQUENT EVENTS

 

a)

Sale of FCI

In January 2019, the board of directors of the Company approved the sale of FCI, our specialty RF IC product line for the Mobile Communications market. On March 7, 2019, the Company entered into a definitive agreement with Dialog Semiconductor Plc for the sale of FCI for US$45 million. The transaction is expected to close in the second quarter of 2019, subject to Korea government approvals.

 

b)

Sale of ProGrade investment

In April 2019, the board of directors approved the sale of the Company’s 49.0% equity interest in ProGrade for $1.7 million. The sale is expected to close in the second quarter of 2019.

 

c)

Shannon Impairment Risk

In April 2019, key customers of our Shannon SSDs notified the Company that their revised full-year 2019 procurement forecasts will be significantly lower than what they had provided to us in January 2019. As a result,

 

F-38


Table of Contents

we reduced our Shannon SSD sales forecast to a level meaningfully below what we had planned in January as part of our annual operating plan. The primary reasons of the recently reduced sales forecast include: (i) increasingly risk-adverse customers have reduced procurement plans relating to SSD solutions based on new, less mature technologies such as ours, (ii) weakening economic conditions in China have caused Chinese data center operators to postpone expansion plans and reduce SSD procurement forecasts, including from us, and (iii) NAND prices have fallen more than we had expected and could fall further, and this will result in less revenue received for the same petabyte of Shannon SSDs that we sell.

The reduced sales forecast represents a triggering event which will require the reevaluation of the reporting unit’s goodwill and intangible assets in the second quarter of 2019. Depending on further development of the situation and factors relevant to a revised financial forecast of the Shannon reporting unit, the impairment assessment may result in impairment of goodwill and of certain intangible assets; however, the Company cannot estimate the amount or a reasonable range of amounts of such impairments, if any, at this time. As of December 31, 2018, the carrying value of the reporting unit’s goodwill was $33.2 million and intangible assets were $1.0 million.
