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 multimedia consumer electronics market;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | decreases in the overall average selling prices of our products;
| | - |  | ----------------------------------------------------------------



| |  |  | changes in the relative sales mix of our products;
| | - |  | --------------------------------------------------



| |  |  | changes in our cost of finished goods;
| | - |  | --------------------------------------



| |  |  | the availability, pricing and timeliness of delivery of other components and raw materials used in our customers products;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | our customers financial health, sales outlook, purchasing patterns and inventory adjustments based on consumer demands, market adoption of new
technologies and general economic conditions;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to successfully develop, introduce and sell 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 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.

Exchange Rate Information

Although a majority of our revenues and expenses are denominated in U.S. dollars, our operational headquarters is in Taiwan and we report
our financial results in NT dollars. This annual report contains translations of NT dollar amounts into U.S. dollar amounts at specific rates solely for the convenience of the reader. The translations of NT dollar amounts into U.S. dollar amounts in
this annual report are based on the noon buying rate in the City of New York for cable transfers of the NT dollar as certified for customs purposes by the Federal Reserve Bank of New York. Unless otherwise noted, all translations from NT dollar
amounts to U.S. dollar amounts and from U.S. dollar amounts to NT dollar amounts in this annual report were made at a rate of NT$31.95 to US$1.00, the noon buying rate in effect as of December 31, 2009. On June 11, 2010, the noon buying
rate was NT$32.40 to US$1.00.

We make no representation that any NT dollar or U.S. dollar amounts could have been, or could
be, converted into U.S. dollar or NT dollar amounts, as the case may be, at any particular rate, the rates stated below, or at all.

The following table sets forth information concerning exchange rates between NT dollars and U.S. dollars for the periods indicated. These
rates are provided solely for your convenience and are not necessarily the exchange rates that we used in this annual report or will use in the preparation of our periodic reports or any other information to be provided to you. The source of these
rates is the Federal Reserve Bank of New York.

Risk Factors

Because our operating results for any period could be adversely affected by a number of factors 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. 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:



| |  |  | continuing downward pressure on the average selling prices of our products caused by intense competition in our industry;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | decreases in demand for multimedia consumer electronics products, including mobile phones, into which our semiconductor solutions are directly or
indirectly incorporated;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our customers financial health, sales outlook, purchasing patterns and inventory adjustments based on consumer demands, market adoption of new
technologies and general economic conditions;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| |  |  | changes in the seasonality of our sales, which generally has a tendency toward increased sales in the second half of each year;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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 as the global economic slowdown results in closures of less efficient fabs and fabs operating at
lower utilization rates;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in the relative sales mix of our products;
| | - |  | --------------------------------------------------



| |  |  | changes in foreign currency exchange rates;
| | - |  | -------------------------------------------



| |  |  | the availability and pricing of third party semiconductor foundry, assembly and test capacity and raw materials, as well as other changes in our cost
of finished goods;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the availability, pricing and timeliness of delivery of other components and raw materials used in our customers products;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



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



| |  |  | superior product innovations by our competitors;
| | - |  | ------------------------------------------------



| |  |  | the timing of new product announcements or introductions by us or by our competitors;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | 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 public market 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.

The current global recession of 2008 and 2009 and the downturn in the semiconductor
industry have adversely affected our operating results and stock price in a material manner.

We operate primarily in
the semiconductor industry, which is cyclical and has, from time to time, experienced significant downturns, most recently in connection with the most recent global downturn. These downturns are frequently characterized by decreases in product
demand, production overcapacity, excess inventories and accelerated erosion of selling prices. These factors could cause substantial fluctuations in our revenue and results of operations. In addition, during these downturns, manufacturers of
components, specifically NAND flash components that are used in our customers products, may choose to reduce their output and reduce availability of NAND flash components to our customers, which would lead to reduced demand for our controller
products. Furthermore, during these downturns some competitors may become more aggressive in their pricing practices, which would adversely impact the prices of our competing products. Any downturns in the semiconductor industry may be severe and
prolonged, and any failure of the industry or our mobile storage, mobile communications, and multimedia SoCs markets to fully recover from downturns could negatively impact our revenue, business, financial condition and results of operations. The
semiconductor foundry industry also periodically experiences increased demand which limit the availability of third-party foundry, assembly and testing capacity and may affect our ability to ship sufficient products to meet our customers
purchase requests. Accordingly, our operating results may vary significantly as a result of the general conditions in the semiconductor industry, which could cause large fluctuations in our stock price.

General worldwide economic conditions significantly deteriorated in 2008 and the first half of 2009. Although conditions in the
semiconductor market in which we participate have recently improved, if general global economic conditions do not continue to improve or deteriorate further, it could adversely affect the semiconductor market and make it extremely difficult for us,
our customers, our vendors, and manufacturers of components that are used in our customers products to accurately forecast and plan future business activities. Furthermore, during challenging economic times, our customers may face issues
gaining timely access to sufficient credit, which could impair their ability to make timely payments. If that were to occur, we may be required to increase our allowance for doubtful accounts and our days sales outstanding for accounts receivable
would be negatively impacted. The recession of 2008 and 2009 and any future downturn may reduce our revenue or our revenue growth and result in our having excess inventory. We cannot predict the timing, strength or duration of any economic slowdown
or subsequent economic recovery, either worldwide, or in the semiconductor industry. If the economy and the markets in which we operate do not improve from current conditions or if they continue to deteriorate, our customers or potential customers
could reduce or delay their purchases of our products, which would adversely impact our revenues and our ability to manage inventory levels, collect customer receivables and, ultimately, adversely impact our profitability. In addition, we may record
additional charges related to the restructuring of our business and the impairment of our goodwill and other long-lived assets, and our business, financial condition and results of operations may be materially and adversely affected.

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

We sell our ICs to original equipment manufacturers
(OEMs) and original design manufacturers (ODMs) that integrate our products into their devices. We have limited visibility as to the volume of our products that our OEM and ODM customers are selling to their customers or
carrying in their inventory. If our customers procure less than expected amounts of other primary components used in their products, specifically NAND flash components, experience a slowing of products sold through to their end customers, or have
excess inventory, our sales orders from customers would likely slowdown, which would adversely impact our future sales and inventory.

We may make acquisitions that are dilutive to existing shareholders, resulting in
unanticipated one-time charges or that may otherwise adversely affect our results of operations, and result in difficulties in assimilating and integrating the operations, personnel, technologies, products and information systems of acquired
companies or businesses.

We continually evaluate and explore strategic opportunities as they arise, including business
combinations and capital investments. If we issue equity securities in connection with an acquisition, the issuance may be dilutive to our existing shareholders. Alternatively, acquisitions made entirely or partially for cash would reduce our cash
reserves.

Mergers and acquisitions of high-technology companies are inherently risky and subject to many factors outside of
our control, and no assurance can be given that our previous or future acquisitions will be successful and will not materially adversely affect our business, operating results, or financial condition. Failure to manage and successfully integrate
acquisitions could materially harm our business and operating results. Even when an acquired company has already developed and marketed products, there can be no assurance that such products will be successful after the closing, will not cannibalize
sales of our existing products, that product enhancements will be made in a timely fashion or that pre-acquisition due diligence will have identified all possible issues that might arise with respect to such company.

In April 2007 we completed the acquisition of Future Communications IC, Inc. (FCI), a privately held Korea-based fabless
mobile TV and wireless communications RF IC design company, and in November 2007 we acquired select parts of the Centronix mobile TV business of Korea Information Engineering Services Co., Ltd. The products from our FCI and Centronix acquisitions
comprise our mobile communications product line. In the fourth quarter of 2009, we determined that goodwill and certain long-lived assets relating to our mobile communication product line are impaired and have taken an impairment charge of US$38.7
million. This is a non-cash impairment charge to GAAP earnings for our 2009 fiscal year and with this impairment charge, the net carrying cost of our mobile communication product line assets at the end of fourth quarter 2009 has been reduced to
US$32.4 million. See We are exposed to potential impairment charges on intangible assets relating to recent acquisitions and on investments if business conditions deterioratebelow.Risks arising from these or other
future acquisitions could include among other things:



| |  |  | our ability to accurately assess the business and prospects of an acquisition or the anticipated benefits of an acquisition;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | delays in or failure to complete the development and application of the acquired technologies or products;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | timing of the rollout and adoption of mobile TV services and standards globally;
| | - |  | --------------------------------------------------------------------------------



| |  |  | our ability to successfully integrate acquired technologies, operations and personnel;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | failure to achieve projected results of the acquisition;
| | - |  | --------------------------------------------------------



| |  |  | disruption of our ongoing business;
| | - |  | -----------------------------------



| |  |  | diversion of management and employees attention from our business;
| | - |  | -------------------------------------------------------------------



| |  |  | risks associated with entering into a geographic region or business market in which we have little or no prior experience and specifically managing
personnel in these regions;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | difficulties in establishing and maintaining uniform standards, controls, policies and procedures;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | deficiencies in the internal control of any acquired company resulting in a material weakness in our overall internal control;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to recover costs of the acquisition or investment;
| | - |  | --------------------------------------------------------------



| |  |  | amortization expenses and large and immediate write-offs;
| | - |  | ---------------------------------------------------------

##### Table of Contents

| |  |  | impairment charges related to goodwill or other assets;
| | - |  | -------------------------------------------------------



| |  |  | negative impact on our relationships with customers, suppliers or contractors;
| | - |  | ------------------------------------------------------------------------------



| |  |  | loss of key employees of acquired business; and
| | - |  | -----------------------------------------------



| |  |  | potentially dilutive issuance of equity securities.
| | - |  | ---------------------------------------------------

In addition, future acquisitions could result in the incurrence of debt or contingent liabilities, adverse tax consequences, deferred
compensation charges, dilution to future earnings, and large fees for professional advisor services, any of which could negatively impact our business financial conditions or results of operations and could cause our stock price to decline. We may
be unable to identify suitable acquisition candidates or investment opportunities or consummate any such transactions on terms and conditions that are acceptable to us, if at all. We may not realize the anticipated benefits of any acquisition or
investment.

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 have derived a substantial
portion of our past 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 38%, 35% and 38% of our net revenue in 2007, 2008 and 2009, respectively. We had one customer in 2007, 2008 and 2009 that accounted for 10% or more of our sales. 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.

Sales to our
customers may be significantly higher if indirect sales are included with direct sales. In 2009, Samsung Electronics was our largest customer and accounted for approximately 17% of our sales. Samsung was also our largest customer in 2008, accounting
for approximately 10% of our sales. We believe a material portion of our sales to other customers are included in products of Samsung Electronics and that such direct and indirect sales to Samsung Electronics amounted to between 19% and 20% of our
sales in 2007, between 15% and 17% in 2008 and between 19% and 20% in 2009.

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.

We operate in intensely competitive industries, and our failure to respond quickly to technological developments and incorporate
new features into our products could harm our ability to compete.

We operate in intensely competitive industries that
experience rapid technological developments, changes in industry standards, changes in customer requirements, and frequent new product introductions and improvements. If we are unable to respond quickly and successfully to these developments, we may
lose our competitive position, and our products or technologies may become uncompetitive. To compete successfully, we must maintain a successful R&D effort, develop new products and production processes, and improve our existing products and
processes at the same pace or ahead of our competitors. We may not be able to develop and market these new products successfully, new markets at which our products target may not grow as expected, the

##### Table of Contents

products we invest in and develop may not be well received by customers, and products developed and new technologies offered by others may affect demand for our products. These types of events
could have a variety of negative effects on our competitive position and our financial results, such as reducing our revenue, increasing our costs, lowering our gross margin percentage, and requiring us to recognize impairments on our assets.

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

The products we develop and sell, especially those for flash memory
storage solutions, are used for high volume applications and many of them are subject to rapid declines in average selling prices. Our average selling prices have historically decreased significantly, and we expect that we will continue to reduce
prices 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 us
or our competitors, competitive pricing pressures and other factors. The semiconductor market is extremely cost sensitive, which may result in declining average selling prices of other components used in our customers products 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.

If we are unable to accurately predict our future sales
and to appropriately budget for our expenses, our results of operations could suffer.

The rapidly changing nature of
the global economy and the markets in which we sell our products limits our ability to accurately forecast quarterly and annual sales. 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.

A failure to accurately forecast customer demand may result in excess or insufficient inventory, which may increase our operating
costs and harm our business.

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.

Industry standards and demands in the multimedia consumer electronics market are
continuously and rapidly evolving, and our success depends on our ability to anticipate and meet these changes and trends.

In order to remain competitive in the future, we must ensure that our products meet continuously evolving industry standards and are
compatible with rapidly changing customer requirements. If our products do not keep pace with evolving industry standards or if our products are not in compliance with prevailing industry standards for an extended period of time, we could be
required to invest significant time, effort and funds to redesign our products to ensure compatibility with relevant standards. If we are slow to anticipate changing trends and respond to such charges in a timely manner, we could miss opportunities
to capture potential customers and we could lose our existing market share or existing customers. Currently, our primary products are controllers used in flash memory storage devices. If new technologies for storing digital media are developed that
compete with flash memory technology or render it obsolete and if we are not able to shift our product offerings accordingly, demand for our products would likely decline and our business would be materially and adversely affected.

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.

If demand for our products declines in the major end-markets that we serve, our selling prices and our overall sales 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. A significant amount of our sales revenue is derived from customers who use our microcontrollers in removable and irremovable flash memory storage solutions used in communications, consumer
electronics and computing devices, such as mobile phones, smart phones, digital cameras, and notebook and desktop PCs. Any significant decrease in the demand for these devices may decrease the demand for our semiconductor solutions and may result in
a decrease in our revenues and earnings. A variety of factors, including economic, political and social instability, could contribute to a slowdown in the demand for non-essential communications, consumer electronics and computing devices as
consumers delay purchasing decisions or reduce their discretionary spending. In addition, the historical and continuing trend of declining average selling prices of communications, consumer electronics and computing devices places pricing pressure
on our semiconductor solutions. As a result, we expect that the average selling prices for many of our semiconductor solutions will continue to decline over the long term. If we are not able to introduce higher margin products or reduce our cost of
sales to offset expected declines in average selling prices, our gross margin will decline, which could have a material and adverse effect on our financial condition and operating results.

If the semiconductor industry suffers a shortage of flash memory, which is a key component in many of our customers end
products, our revenues could be adversely affected.

In 2005, 2007, and 2009, some of our customers indicated that they
were unable to acquire enough flash memory to meet all of the anticipated demand for their products. Several manufacturers of flash memory have increased or are planning to increase manufacturing capacity for flash memory. However, we cannot assure
you that there will continue to be enough additional capacity to satisfy worldwide demand for flash memory. Because flash memory is a key component in many of the products manufactured by our customers, if any shortage in the supply of flash memory
occurs and is not remedied, our customers may not be able to purchase enough flash memory to manufacture their products and may therefore purchase fewer controllers from us than they would have otherwise purchased. Our ability to increase revenues
and grow our profits could be materially and adversely affected as a result of any shortage or decrease in the supply of flash memory.

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 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 refine the existing hardware
system and application programming interface and to introduce enhancements 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 management 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 uncertainties involving the Taiwanese, Chinese, or Korean legal systems.

We may be unsuccessful in developing and selling new products or in penetrating new markets required to maintain or expand our
business.

Currently, we sell most of our solid state storage controller solutions to manufacturers of flash memory
cards and USB flash drives. Flash memory cards were originally used in digital still cameras as storage for digital pictures and videos. The market for flash memory cards expanded significantly as smaller form factor cards were developed,
NAND flash component and controller prices decreased, and mobile phone manufacturers incorporated embedded cameras and other advanced multimedia functionalities and card slots into their products to utilize flash memory cards as primary storage for
pictures, video, music, and other data generated or enjoyed by consumers of mobile phones. The market for flash memory cards further expanded as the categories of mobile phones that utilize flash memory cards as data storage expanded from
camera phones to smart phones. The market for USB flash drives is principally related to the PC market as USB flash drives are popularly used as peripheral storage for desktop and notebook PCs. We have been successful in developing
controllers for flash memory cards used in digital cameras, camera phones, and smart phones and controllers for USB flash drives used with desktop and notebook PCs. The future growth of our mobile storage revenue, if any, will depend in part on
our ability to expand beyond the digital camera, mobile phone, and PC markets and the flash memory card and USB flash drive markets, particularly into markets for solid state drives and embedded memory applications.

Currently, we sell most of our mobile TV IC solutions to Korean manufacturers of handsets and navigation devices for the domestic Korean
market. The future growth of our mobile communications revenue, if any, will depend in part on our ability to expand beyond the Korean market to emerging mobile TV markets such as China, Brazil, the United States, and Europe and the mature
Japanese market.

Each of these markets, whether for solid state storage controllers or mobile TV IC solutions, present
distinct and substantial risks. Most of these markets are new, still developing, and relatively small. If any of the new

##### Table of Contents

markets does not develop as we currently anticipate or if we are unable to penetrate it successfully, our overall corporate revenue and revenue growth rate, if any could be materially and
adversely affected.

If we fail to penetrate these other new markets upon which we target our resources, our revenue and
revenue growth rate, if any, will likely decrease over time and our financial condition could suffer.

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 a semiconductor fabrication facility. Instead, we rely on third parties to manufacture our semiconductors. Five
outside foundries, Silterra in Malaysia, Taiwan Semiconductor Manufacturing Company (TSMC) in Taiwan, Semiconductor Manufacturing International Corporation (SMIC) and Grace Semiconductor Manufacturing Corporation
(Grace) in China, and STMicroelectronics in Europe currently manufacture the majority of our semiconductors. As a result, we face several significant risks, including higher wafer prices, 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. 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 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 as long as six months, resulting in unforeseen operations 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 pertinent subcontractors in
the various phases of the assembly and testing processes.

##### Table of Contents

We also emphasize a strong supplier quality management practice through which our quality assurance team pre-qualifies 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 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 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 would 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.

We currently have more than 118 patents and 506 patent applications pending in five countries. 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 have been engaged 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 which 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 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 the technology. See Legal Proceedings.

##### Table of Contents

In addition, any litigation, whether 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 management.

Failure to achieve and maintain technological leadership in our various multimedia
consumer electronics markets could erode our competitiveness and cause our profits to decrease.

The consumer
electronics market and the semiconductor components used in such market are constantly changing with increased demand for improved features such as lower power or smaller size. If we do not anticipate these changes in technologies and rapidly
develop and introduce new and innovative technologies, we may not be able to provide advanced semiconductor solutions on competitive terms. If we are unable to maintain the ability to provide advanced semiconductor solutions on competitive terms,
some of our customers may buy semiconductor solutions from our competitors instead of us. To be competitive, we must anticipate the needs of the market and successfully develop and introduce innovative new products in a timely fashion. We cannot
assure you that we will be able to successfully complete the design of our new products, have these products manufactured at acceptable manufacturing yields, or obtain significant purchase orders for these products. Furthermore, if our future
innovations are ahead of the then-current technological standards in our industry, customers may be unwilling to purchase our platforms until the multimedia consumer electronics market is ready to accept them. The introduction of new products may
adversely affect sales of existing products and contribute to fluctuations in our operating results from quarter to quarter. Our introduction of new products also requires that we carefully manage our inventory to avoid inventory surplus and
obsolescence. Our failure to do so could have a material and adverse effect on our operating results. Furthermore, failure to achieve advances in technology or processes or to obtain access to advanced technologies or processes developed by others
could erode our competitive position.

Development of new platforms and products may require us to obtain rights to use
intellectual property that we currently do not have. If we are unable to obtain or license the necessary intellectual property on reasonable terms or at all, our product development may be delayed, the gross margins on our planned products may be
lower than anticipated and our business and operating results would be materially and adversely affected.

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 market place.

We face competition from a large number of competitors in each of our target markets. Our primary competitors in our mobile storage market
include Alcor Micro, Chipsbank, Hyperstone, J-Micron, Phison, Samsung, Skymedi, Solid State Systems, and ITE. For multimedia SoCs products, the companies with whom we compete include Actions, ALi, Freescale, Fujitsu, Novatek, Rockchip, Sonix,
Vimicro and XGI. For mobile communications products, the companies with whom we compete include Analog Devices, DiBcom, Frontier Silicon, GCT Semiconductor, I&C Technology, Maxlinear, Murata, Nexilion, Qualcomm, Siano, and Toshiba. We expect to
face increased competition in the future from our current and potential competitors. In addition, some of our customers have developed products and technologies that could replace their need for our products or otherwise reduce their demand for our
products.

Many 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. In addition, in the event of a manufacturing capacity shortage, these competitors may be able to obtain capacity when we are unable to do so.

The multimedia consumer electronics market, which is the principal end market for our
products, has historically been subject to intense price competition. In many cases, low-cost, high-volume semiconductor component producers have entered markets and driven down profit margins. If a low-cost, high-volume producer should develop
products that compete with our products, our sales and profit margins would suffer.

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 some instances, our products are designed for use in devices manufactured by our customers that comply with international
standards, such as the MP3 compression standard. These international standards are often covered by patent rights held by third parties, which may include our competitors. The combined costs of identifying and obtaining licenses from all holders of
patent rights essential to such international standards could be high and could reduce our profitability or increase our losses. The cost of not obtaining these licenses could also be high if a holder of the patent rights brings a claim for patent
infringement. In the contracts under which we distribute semiconductor products, we generally 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 licensor 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 intangible assets relating to recent acquisitions and on investments if business conditions deteriorate.

We
are required to perform testing for impairment losses for long-lived assets used in operations when indicators of impairment, such as reductions in demand or significant economic slowdowns in our business, are present. In November 2009, we recorded
NT$217.2 million (US$6.8 million) of impairment charges relating to our long-lived assets. We performed our annual impairment assessment of the carrying value of the goodwill in November 2009, determined that the goodwill balance was impaired, and
wrote down the goodwill balance by NT$1,019.4 million (US$31.9 million). Through our acquisitions of FCI and Centronix, we have acquired core technology, customer relationships, goodwill and other intangible assets. As of December 31, 2009, the
Company has goodwill associated with our acquisitions of NT$1,168.8 million (US$36.6 million) and net acquired intangible assets of NT$92.4 million (US$2.9million). Goodwill must be tested for impairment at least on an annual basis. Although we
recorded an impairment on goodwill and other long-lived assets during 2009, we cannot be certain that these assets will not be subject to further write-downs in future periods.

In addition, we have made investments in private companies. If the companies that we invest 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 investments on a regular basis to determine if



14

##### Table of Contents

impairments have occurred and have recorded impairment charges in 2009 and past years. These and future impairment charges could have a material impact on our operating results. In 2007, 2008 and
2009, we recorded impairment charges relating to our private company investments of NT$14.4 million, NT$69.3 million, and NT$8.6 million (US$0.3 million), respectively.

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 a management report on such
companys internal controls over financial reporting in its annual report, which contains 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, 2009
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.

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-demand dynamics;
| | - |  | -------------------------------------------------------------------



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



| |  |  | the commencement or results of litigation;
| | - |  | ------------------------------------------



| |  |  | announcements by us or our competitors of new products or technological innovations;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | changes in financial estimates or recommendations by securities analysts;
| | - |  | -------------------------------------------------------------------------



| |  |  | announcements by us or our competitors of significant acquisitions or partnerships; and
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | actual or anticipated changes in the global economic 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.

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

We conduct our business worldwide. We are headquartered in Taiwan 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, Europe, Korea,
Malaysia and Taiwan. We generated 94%, 94% and 93% of our revenue in 2007, 2008 and 2009, respectively, from sales to customers outside the United States. 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 Taiwan and Korea);
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



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



| |  |  | imposition of additional taxes and penalties; and
| | - |  | -------------------------------------------------



| |  |  | other factors beyond our control such as 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 NT dollar, 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 renminbi, and U.S. dollar. As a result, appreciation or depreciation of other currencies
in relation to the NT 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.

Taiwan and parts of China and the United States are susceptible to earthquakes. In 1999 and 2008, Taiwan and China,
respectively, experienced severe earthquakes that caused significant property damage and loss of life. 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.

While we also, through our acquisition of FCI, maintain substantive operations in Korea, our principal executive offices and 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 Grace, SMIC, Taiwan IC Packing Corp. (TICP), TSMC,
and Youngtek Electronics Corp. (YTEC) 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 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



16

##### Table of Contents

declaration of independence by Taiwan or the refusal by Taiwan to accept Chinas stated one China policy. On March 14, 2005, the National Peoples Congress of China
passed what is widely referred to as the anti-secession law, a law authorizing the Chinese military to attack in order to block moves by Taiwan toward formal independence. Past developments in relations between Taiwan and China have on
occasion depressed the market prices of the securities of Taiwanese companies. 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 of our ADSs.

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.

The Taiwanese and South Korean governments have been supportive of technology companies such as ours. In particular, we, like many
Taiwanese technology companies, have benefited from tax incentives provided by the Taiwanese government. For example, under the Statute for Upgrading Industries of Taiwan, we are 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. The Statute for Upgrading Industries of Taiwan expired at
the end of 2009 and previously granted tax credits and preferential tax treatments have been cancelled. However, we are still eligible to use certain previously granted unutilized, unexpired tax credits and exemptions. See Operating and
Financial Review and Prospects  Principal Factors Affecting Our Results of Operations  Provision for income taxes and note 14 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 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 tax credit for investments made to improve business productivity. If these
and other tax incentives are curtailed or eliminated, our net income may decrease materially.

We face substantial
political risk associated from doing business in South Korea because of tension 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, and more recent concerns over North
Koreas nuclear and ballistic missile capabilities, hostile actions by North Korea against South Korea, 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. An adverse change in economic or political conditions in South Korea or in its relations with North Korea could have
a material adverse effect on our South Korea subsidiary and our company.

Industry Background

The
convergence of consumer electronics, communications, and computing devices has been accelerating at a fast rate in recent years as advances in technology enable different categories of electronic devices to offer similar functionalities, which often
involve the processing, storage, and transfer of digital multimedia content. Mobile phones for example have been transformed into multimedia consumer electronics devices with camera, video recorder, music player, e-mail, Internet access, electronic
games, television, and other functions, because mobile phones have increasingly sophisticated multimedia applications processing, data storage, and data transfer capabilities. Personal computers have also been transformed into multimedia consumer
electronics devices by multimedia data processing, storage, and transfer technologies that include wireless connectivity, Internet telephony, video telephony, and more advanced video and audio capabilities. Several important semiconductor technology
developments have led to the significant improvement by electronics devices to process, store, and transfer digital multimedia content and these include the development of NAND flash as a widely used data storage medium, high-performance multimedia
application processors and advanced communication-related RF ICs.

Our Markets and Products

We design, develop and supply a portfolio of multimedia data processing, storage, and transfer solutions targeted primarily at consumer
electronics applications. Our current product offerings address three main markets: mobile storage, multimedia SoCs and mobile communications markets. The following is a brief description of each of our markets.

Mobile Storage Products

We offer a broad range of controllers for NAND flash memory storage products, including flash memory cards, USB flash drives, card
readers, embedded flash and solid state drives. Flash memory storage products are widely used by consumers to store data for multimedia consumer electronics devices such as mobile phones, digital still cameras, camcorders, personal navigation
devices, personal multimedia players, and notebook and desktop PCs. Flash memory cards and USB flash drives are two of the largest end applications for NAND flash.

Our controllers are designed to be compatible with and the companion IC to the vast majority of NAND flash produced by companies such as Hynix, Intel, Micron, Numonyx, Samsung, SanDisk and
Toshiba. Because NAND flash from different manufacturers may be dissimilar in terms of IC packaging, input/output timing, command code and other factors, a controller plays an important role in ensuring NAND flash used in flash memory storage
products are compatible with consumer electronics host devices. New NAND flash from different manufacturers or the same vendor may require new silicon microcontroller solutions, updates to the firmware in the controller, extensive and thorough
debugging and testing of the controller with the updated NAND flash driver and extensive and thorough compatibility testing of the NAND flash memory storage product.

Key functions of our flash memory card and USB flash drive controllers include:



| |  |  | managing data input and output between the NAND flash in the flash memory storage product and the consumer electronics host device;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | ensuring that flash memory storage products which use our controllers are compatible with the widest possible universe of consumer electronics host
devices;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | ensuring data reliability in NAND flash by detecting and correcting individual bit errors in the NAND flash;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | ensuring data integrity in a NAND flash by mapping bad blocks and preventing the bad blocks from being used for storing data;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | maximizing the life of a NAND flash with wear-leveling algorithms which spread out the use of the memory array and equalizes the use of all the memory
cells;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | enhancing the read and write performance of NAND flash by utilizing two-plane architecture, interleaving, or other technologies; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | implementing security features to protect software code, personal data and multimedia digital rights.
| | - |  | -----------------------------------------------------------------------------------------------------

Flash memory card controllers.NAND flash memory cards are non-volatile, solid state storage media that have become the
predominate media for the storage of multimedia data used in mobile phones, digital still cameras and other portable consumer electronic devices because of their small and compact form factor, large storage capacity, low power consumption, high
speed data transfer rate, and support of certain copyright protection technologies.

We believe we offer the broadest line of
high-performance controllers for all major NAND flash memory card formats, including Compact Flash (CF), MultiMedia Card (MMC), Secure Digital (SD) and Memory Stick (MS), as well as sub-types of these
formats, such as SD cards miniSD card and microSD card. We believe that our controllers are compatible with the majority of NAND flash currently being produced by different flash memory manufacturers, including small and big block Single-Level
Cell (SLC) and Multi-Level Cell (MLC) NAND flash. Our controllers also support two-bits per cell MLC and three-bits per cell MLC NAND flash.

Our proprietary IC design methodology, strong firmware capability, proprietary assembly techniques and comprehensive testing procedures
enable us to offer controllers that have significant competitive advantages with respect to compatibility, speed, connectivity and cost. Based on our proprietary QuickWrite technology, we believe our controllers outperform competing products on
product benchmarking tests. Our FastMDC, Block EarlyRetirement, and PowerCycling technologies enable high performance and high reliability data storage. Our flash memory controllers are also designed for very low stand-by power consumption, to
withstand electro-static discharge and to allow flexible flash memory configuration through both hardware and firmware. Our flash memory card controller ICs are manufactured primarily using standard CMOS processes at 0.13- and 0.18- micron.

USB flash drive controllers. USB flash drives are NAND flash memory data storage
devices integrated with a standard USB interface, commonly high speed USB 2.0. They are typically small, lightweight, removable and rewritable. USB flash drives are more compact, generally faster, have large capacity for data and are more robust and
reliable than other types of portable storage devices such as hard disk drives and CD or DVD optical storage medium used with optical drives.

Our high performance USB flash drive controllers can support single- and dual-channel SLC and MLC NAND flash configuration and are
compatible with the majority of flash memory currently being produced by different flash memory manufacturers. They are designed for high data transfer rates, low power consumption, offer our customers an overall low cost solution with integrated
voltage regulators and stand-by power components and support Master and Slave SPI (Serial Peripheral Interface) for applications such as a fingerprint sensor.

Other storage controllers. In addition to controllers for flash memory cards, USB flash drives and card readers, we also offer
controller solutions for embedded flash memory and controllers for solid state drives (SSDs). SSD is a next generation storage technology designed to replace or compliment hard disk drives. SSDs are potentially faster in terms of data
read/write speed, more durable and not prone to mechanical malfunction, more power efficient and generate less heat, quieter, and smaller in form factor. Our embedded controller solutions include controllers mounted on the printed circuit board of
electronic devices, used to control NAND flash also mounted on the printed circuit board of the device, as well as controllers contained in a single semiconductor package with one or more companion NAND flash dies. In 2007, we started shipping
controllers for solid state drives and embedded memory solutions for use in industrial, networking, and consumer applications, notebook PCs and servers.

Multimedia SoCs

We design and develop a wide range of multimedia SoCs for embedded graphics applications and notebook PC webcams. SoCs are integrated
circuits that include a central processing unit, memory interfaces and other components and that address a range of end application requirements, including low power, high performance, low cost and high levels of system integration. Our SoCs are
manufactured using standard CMOS processes.

Embedded graphics processors.Graphics processors are commonly used by
desktop and notebook PCs, game consoles, work stations and multimedia mobile phones to increase the speed and complexity of images that can be displayed on a monitor, TV or screen, as well as improve color definition and image resolution. Graphics
processors are also used to control the displays of servers and a wide range of consumer and lifestyle, medical and industrial, office equipment, entertainment and other products.

Before we combined our business with Feiya in 2005, SMI USA was principally a graphics processor company. We are currently focused
primarily on designing, developing and marketing high-performance, low-power SoCs which contain a graphics processor engine and embedded memory and are highly integrated and low cost, small in chip size, easy to design-in by systems integrators, and
fully supported and not end-of-life. The markets in which we compete include low-end servers, consumer and lifestyle products, medical and industrial applications, office equipment and other machines. Our embedded graphics processors are generally
used to render text, 2D graphics and graphical user interface on displays.

Based on our DualMon
technology, our graphics processors can drive two separate displays using one processor. This saves on costs as well as space on mother boards. Our
ReduceOn® technology enables intelligent power management which algorithmically varies the clock and power to
functional units based on system needs to significantly reduce average operating power usage. End-users can thus use the mobile devices for longer periods without a reduction in performance.

Image processors. With improvements in the bandwidth of broadband internet access and
video telephony software, consumers are increasingly using desktop and notebook PCs equipped with webcams to conduct video telephony and conferences. An image processor is required to process and enhance the image captured by the CMOS image sensors
located behind the lens of a webcam.

Our single chip image controller for PC camera solutions supports CMOS image sensors of
up to 2.0 megapixels. Our SoC integrates a color processor engine, JPEG compression, AC-Link/IIS audio interface and high-speed USB 2.0 device controller and also supports all legacy PC systems equipped with USB 1.1 host interfaces.

Mobile Communications

Beginning in May 2007, we started offering semiconductor solutions for mobile TV, CDMA mobile phones, and electronic toll collection
systems. Our new mobile communications portfolio of products became a part of our company following the completion of our acquisition of FCI at the end of April 2007. FCI was formerly a mobile communication RF IC company that focused on developing
IC solutions for receiving mobile TV signals on mobile phones, as well as receiving and transmitting voice, video and data on mobile phones.

Mobile TV IC Solutions.Our products include mobile TV tuners and integrated tuner plus demodulator SoCs for mobile phones and
other portable devices. Our solutions are designed for many mobile TV broadcast standards including T-DMB, ISDB-T, DVB-H/T, CMMB and ATSC-M/H. According to competitor product benchmarking, we believe our mobile TV tuners and SoCs are among the most
competitive in the market in terms of smallest chip size, lowest power consumption, lowest noise and high adjacent channel selectivity.

CDMA RF ICs.We offer CDMA transceivers for VIA and certain Qualcomm modem solutions.

Electronic toll collection system RF ICs.We are a leading supplier of transceiver ICs for Koreas electronic toll collection
system.

##### Table of Contents

The majority of our customers purchase our products through purchase orders, as opposed to
entering into long-term contracts with us. The price for our products is typically agreed upon at the time a purchase order is placed.

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 major OEM and ODM customers in Taiwan, Korea, China,
the United States, and Japan. Approximately 82% of our sales in 2007, 74% of our sales in 2008 and 73% of our sales in 2009 were attributable to our direct sales force while the remainder was attributable to distributors.

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

Our marketing groups focus on our product strategy, product development road maps, new product introduction process, demand assessment,
competitive analysis, and corporate communications. We seek to work with potential and existing customers early in their design process in order to best match our products to their needs, and more broadly, 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 Card Association for flash memory cards, helps us monitor the latest industry developments and promote our corporate profile. Our marketing groups also work with our sales teams to identify new business
opportunities.

We also have field application engineers, or 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 products and
solutions. Our engineering team has expertise in system architecture, digital, mixed-signal and RF IC design, and software engineering. As of June 18, 2010, we had 118 patents in China, Japan, Korea, Taiwan, and the United States and 506
patents pending. We continue to actively pursue the filing of additional patent applications in China, Japan, Korea, Taiwan, and the United States.

We believe technology research and product development are essential to our growth. Our primary research and development centers are
located in Hsinchu and Taipei, Taiwan, Seoul, South Korea, Shanghai and Shenzhen, China and Milpitas, California. Our facilities in Milpitas focus primarily on graphics products, our facilities in Seoul focus primarily on mobile communications
products, and our facilities in Hsinchu, Taipei, Shanghai and Shenzhen focus primarily on mobile storage and other products.

Our research and development expenses were approximately NT$822.7 million, NT$1,080.9 million and NT$1,122.5 million (US$35.1 million)
for the years ended December 31, 2007, 2008 and 2009, 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

##### Table of Contents

finished ICs 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 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 in Taiwan, SMIC and Grace in China, Silterra in Malaysia and STMicroelectronics in Europe are currently our primary foundries that manufacture most of our semiconductors. Our foundries in Taiwan, Malaysia and China currently
fabricate our devices using mature and stable CMOS process technology primarily with line-widths of 0.09-, 0.13-, 0.16-, 0.18-, and 0.25- micron. We also rely on STMicroelectronics as our foundry for mobile communications products using Bi-CMOS
process technology primarily with line-widths of 0.25 and 0.35 micron. 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 die, assembled into finished IC packages, 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 SPIL, TICP, King Yuan Electronics, YTEC and Giga Solution Tech in Taiwan and Amkor in Korea 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, 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 November 18, 1999.

Competition

The semiconductor industry is characterized by intense competition. Our customers face supply shortages or oversupply,
rapid technological changes, evolving industry standards and declining average selling prices.

Our primary competitors in our
mobile storage market include Alcor Micro, Chipsbank, Hyperstone, J-Micron, Phison, Samsung, Skymedi, Solid State Systems and ITE. For multimedia SoCs products, the companies with whom we compete include Actions, AMD, Freescale, Fujitsu, Novatek,
Rockchip, Sonix, Vimicro and XGI. For mobile communications products, the companies with whom we compete include Analog Devices, DiBcom, Frontier Silicon, GCT Semiconductor, I&C Technology, Maxlinear, Murata, Nexilon, Qualcomm, Siano, and
Toshiba.

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, copyright rights, trademark registrations, trade secret laws, contractual provisions, licenses, and other methods to protect our
intellectual property.



24

##### Table of Contents

As of June 18, 2010, we held 118 patents in the United States, Taiwan, and other
countries and have 506 pending patent applications in the United States, Taiwan, and other countries. 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 any
valid and infringed 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.

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, airRF, basicRF, ezRF, ezSYS, powerRF,
twinRF, zipRF, zipSYS, SSDLifeGuard, SSDLifeSaver, and TurboMLC 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

Our
corporate headquarters are located in Hsinchu, Taiwan. We own this 108,800 square feet facility, which houses our management and administration, operations, and research and development departments. In Taiwan, we also lease premises in
Taipei, occupying approximately 36,300 square feet of floor space, which houses our sales and marketing, as well as research and development departments.

In addition to these facilities in Taiwan, we also purchased in 2008 the facility in Shanghai with an aggregate floor space of
approximately 15,900 square feet for US$4.0 million. We lease facilities in Seoul, Korea, Shenzhen, and Beijing, China, Milpitas, California, and Yokohama, Japan for research and development, sales and marketing, as well as
administration. These facilities in aggregate consist of approximately 59,400 square feet of floor space with lease terms expiring at various dates between 2010 and 2014. In 2004, we entered into an agreement to acquire 6,300 square feet
of floor space of a multi-story building in the suburbs of Seoul for NT$235.3 million (US$7.2 million); this construction project was terminated by its developer in December 2009.

For the years ended December 31, 2007, 2008 and 2009 we derived approximately 41%, 39%, and 36% respectively, of our net sales from
customers located in Taiwan and approximately 6%, 6%, and 7% respectively, of our net sales from customers located in the United States. We anticipate that a majority of our net sales will continue to come from customers located outside of the
United States. The percentages of our net sales by geographic area for the periods indicated were as follows:

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, it generally
requires approximately three months 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 multimedia consumer electronics market such as mobile phones, DSCs,
desktop and notebook PCs, we expect our business to be subject to seasonality, with increased net sales in the second half of each year, when customers place orders to meet increased demand for year-end holiday seasons, and decreased net sales in
the first half of each year. However, our rapid sales growth in the past and recent sales decline makes it difficult for us to assess the impact of seasonal factors on our business.

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, for example, SDRAM used with our graphics processors; and
| | - |  | --------------------------------------------------------------------------------



| |  |  | write-off 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,
and will likely fluctuate as our market conditions change.

Research and development expenses. Our research and
development expenses consist primarily of employee salaries and contractor 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 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. We expect research and development expenses to increase in absolute terms in future periods as our net sales increase.

##### Table of Contents

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. We expect that our sales and marketing expenses will increase in absolute
terms over the next several years as our net sales increases.

General and administrative expenses. Our general and
administrative expenses consist primarily of general employee salaries and related costs, stock-based compensation expense, insurance premiums, professional fees and allowance for doubtful accounts. We expect that general and administrative expenses
will increase in absolute terms in future periods as our net sales increase.

Amortization of acquired intangible assets.Amortization of acquired intangible assets relates to intangible assets, such as core technology and customer relationships, but excluding goodwill, acquired in the FCI and Centronix acquisitions.

Acquired in-process research and development.Acquired in-process research and development relates to the in-process research and
development expensed upon the acquisition of FCI as it was determined that the underlying projects had not reached technological feasibility and no alternative future uses existed.

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

Accounting for
stock-base compensation.We estimate the fair value of share-based payment awards on the date of grant using the Black-Scholes option-pricing model and recognize stock compensation expense over the requisite service period of the individual
grantees, which generally equals the vesting period.

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 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 and deductions, 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. Significant changes to these estimates may result in an increase or decrease to our tax provision in a subsequent period.

We have operations in several countries and determine income taxes for each of the jurisdictions where we operate. Taiwan and
Korea are our two primary countries of operations.

In Taiwan, we have received tax exemptions from the government that are
valid for a number of years and for certain income streams attributable to expanded production capacity or newly developed technologies. We also receive significant amounts of tax credits for applicable research and development expenses
incurred in Taiwan and Korea. Because of these and other tax benefits, the effective tax rates of our Taiwan and Korea operations have been and will continue to be lower than statutory tax rates. See Risk Factors for the risks
relating to our ability to enjoy favorable tax policies of the Taiwanese and Korean governments.

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.



28

##### Table of Contents

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 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, goodwill, long-lived assets, long-term investments, 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. Revenue
from product sales are generally recognized upon shipment to the customer provided that we have received a signed purchase order, the price has been fixed or is determinable, transfer of title has occurred in accordance with the shipping terms
specified in the arrangement with the customer, collectability from the customer is considered reasonably assured, product returns are reasonably estimable and there are no remaining significant obligations or customer acceptance requirements.

We record reserves to cover the estimated returns from our customers. Certain of our distributors have limited rights of
return and price protection rights on unsold inventory. The return rights are generally limited to five percent of the monetary value of products purchased within the preceding six months, provided the distributor places a corresponding restocking
order of equal or greater value. The 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. However, because of the inherent nature of estimates, actual returns and allowances could be significantly different from our estimates. To the extent rates of return
change, our estimates for the reserves necessary to cover such returns would also change which could have a negative impact on our recorded revenue and gross margin. As of December 31, 2007, 2008 and 2009, our allowance for sales returns and
discounts was approximately NT$45.8 million, NT$35.8 million and NT$58.0 million (US$1.8 million), respectively, representing approximately 0.8%, 0.6% and 2.0% of our gross sales for those respective periods.

Occasionally, we have reduced our product pricing due to market conditions, competitive considerations and other factors. Price
protection rights are granted to certain distributors under our distribution agreements. When we reduce the price of our products, it allows the distributor to claim a credit against its outstanding accounts receivable balances based on the new
price of the inventory it has on hand as of the date of the price reduction. A reserve for price adjustments is recorded at the time of sale based on our historical experience. Our reserve for price adjustments to distributors were NT$74 thousand,
NT$6 thousand and NT$381 thousand (US$12 thousand) in 2007, 2008 and 2009, respectively.

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 apply upon transfer of title. On an ongoing basis, we analyze the
payment history of customer accounts, including recent



29

##### Table of Contents

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 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.

As of December 31, 2008 and 2009 our allowance for trade-related doubtful accounts was approximately NT$180 million and NT$97.8
million (US$3.1 million), respectively, representing approximately 14.8% and 14.7% 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 provide reserves for inventory on
hand in excess of the estimated demand. As of December 31, 2007, 2008 and 2009, we wrote down NT$41.6 million, NT$222.3 million and NT$214.4 million (US$6.7 million), respectively, for estimated obsolete or unmarketable inventory.

Stock-based compensation.We recognize stock compensation expense over the requisite service period of the individual grantees,
which generally equals the vesting period.

Determining the appropriate fair-value model and calculating the fair value of
share-based awards at the date of grant using the valuation model requires judgment. We use the Black-Scholes valuation formula to estimate the fair value of employee stock options. Option pricing models, including the Black-Scholes formula, require
the use of input assumptions, including expected volatility, expected term, expected dividend rate and expected risk-free rate of return. Risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. Expected
volatilities are based on historical volatilities of stock prices of Silicon Motion. We estimated our options expected terms using our best estimate of the period of time from the grant date that we expect the options to remain outstanding. If
we determined that another method for estimating expected volatility or expected term is more reasonable than our current methods, or if another method for calculating these input assumptions was prescribed by authoritative guidance, the fair value
calculated for future share-based awards could change significantly from those used for past awards, even if the critical terms of the awards are were similar. Higher volatility and expected terms result in an increase to share-based compensation
determined at the date of grant. The expected dividend rate and expected risk-free rate of return are not as significant to the calculation of fair value.

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



30

##### Table of Contents

management estimates of assets useful lives and future cash flows. Actual useful lives and cash flows could be different from those estimated by our management. This could have a material
effect on our operating results and financial condition. In 2009, we recognized impairment losses of approximately NT$217.2 million (US$6.8 million).

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s net assets as of the respective year end.
During 2007, 2008 and 2009, we recognized impairment losses of approximately NT$14.4 million, NT$69.3 million and NT$8.6 million (US$0.3 million), respectively in long term investments in Spright Co., Ltd. and Vastview Technology, Corp. as a result
of recurring operating losses and reduced forecasts of the investee companies which indicated that Silicon Motions 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 amortize acquisition-related identified intangibles on a straight-line basis over their estimated economic lives of four years for core technology, four years for customer relationships and three months for order backlog.

We measure and test goodwill on an annual basis or more frequently if we believe indicators of impairment exists. 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. 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 applying fair value-based tests to individual assets and liabilities.

We completed our most recent annual impairment test and recorded an impairment charge of NT$1,019.4 million (US$31.9 million) for
the year ended December 31, 2009. This assessment is based upon a discounted cash flow analysis and analysis of our market capitalization. The estimate of cash flow is 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 base
our fair value estimates on assumptions we believe to be reasonable but that are unpredictable and inherently uncertain. The long-term financial forecast represents the best estimate that we have at this time and we believe that its underlying
assumptions are reasonable. However, actual performance in the near-term and longer-term could be materially different from these forecasts, 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 a write-down of goodwill in connection with such 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. This process involves estimating our actual



31

##### Table of Contents

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. We have provided 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 such determination was made.

Effective January 1, 2007, the Company adopted standards
that clarified the accounting for uncertain tax positions. The new standard defines the threshold for recognizing the benefits of tax return positions in the financial statements as more-likely-than-not to be sustained by the taxing
authorities based solely on the technical merits of the position. If the recognition threshold is met, the tax benefit is measured and recognized as the largest amount of tax benefit that, in our judgment, is greater than 50% likely to be realized.
The total amount of unrecognized tax benefits as of December 31, 2007, 2008 and 2009 was NT$137.4 million, NT$208.5million and NT$321.2 million (US$10.1 million), respectively, excluding accrued interest and penalties. As of December 31,
2009, NT$6.9 million (US$0.2 million) of interest and penalties was accrued. Fiscal year 2007 through 2009 remains subject to examination by the US Internal Revenue Service. Fiscal years 2004 through 2009 remain subject to
examination by 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 will change significantly. See Note 14 to the Consolidated Financial
Statements for further information regarding changes in unrecognized tax benefits during 2009.

Litigation and
contingencies. From time to time, we have been subject to legal proceedings and claims with respect to such matters as patents and other actions arising out of the normal course of business, as well as other matters identified in Legal
Proceedings, in Item 8 of this Annual Report. Our success and future revenue growth will depend, in part, on our ability to protect our intellectual property. We rely on a combination of patent, copyright, trademark and trade secret laws,
as well as nondisclosure agreements and other methods, to protect our proprietary technologies. We have been issued patents and may have additional patents in the future; however, we cannot provide assurance that any patent will be issued as a
result of any applications or, if issued, that any claims allowed will be sufficiently broad to protect our technology. In addition, it is possible that existing or future patents may be challenged, invalidated or circumvented. It may be possible
for a third party to copy or otherwise obtain and use our products or technology without authorization, develop corresponding technology independently or design around our patents. Effective copyright, trademark and trade secret protection may be
unavailable or limited in foreign countries. These disputes may result in costly and time consuming litigation or the license of additional elements of our intellectual property for free.

It is possible that other companies might pursue litigation with respect to any claims such companies purport to have against us. The
results of any litigation are inherently uncertain. In the event of an adverse result in any litigation with respect to intellectual property rights relevant to our products that could arise in the future, we could be required to obtain licenses to
the infringed technology, pay substantial damages under applicable law, cease the use and sale of infringing products or to expend significant resources to develop non-infringing technology. Litigation frequently involves substantial expenditures
and can require significant management attention, even if we ultimately prevail.

We have been or are currently involved in
various claims and legal proceedings and have incurred certain costs associated with defending litigation matters. Periodically, we review the status of each significant matter



32

##### Table of Contents

and assess the potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, we accrue 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.

Given the uncertainties associated with litigation, if our assessments prove to be wrong, or if additional information becomes available
such that we estimate that there is a possible loss or possible range of losses associated with these contingencies, then we would record the reasonably estimated liability, which could have a material and adverse effect on our operations, financial
condition and cash flows.

Our net sales
decreased 48% year-over-year to approximately NT$2,893.2 million (US$90.6 million) in 2009 as total unit shipment for our products decreased 37% and average selling prices declined 17%.

Our mobile storage unit sales decreased 37% year-over-year as NAND flash manufacturers reduced their production during the worldwide
economic recession and reduced their sales to our mutual customers. Since our customers procured fewer NAND flash components and manufactured fewer NAND flash storage devices, they also procured fewer controllers from us. Mobile storage
ASPs declined 34% due to intense competition and revenue declined 56%. Mobile communications revenue declined 25% because 2008 revenue included a large non-recurring sale to China and 2009 revenue was negatively affected by mobile TV product
transitions and an economic recession in Korea. Multimedia SoCs revenue declined 13% because our graphics product sales were affected by weak economic conditions in Japan and other important markets

Gross profit
as a percentage of net sales declined from 47% in 2008 to 41% in 2009 primarily because of obsolete and unmarketable inventory write-downs. Our gross profit excluding obsolete and unmarketable inventory write-downs as a percentage of revenue
declined from 51.0% in 2008 to 49.0% in 2009, as declining average selling prices was partially offset by a decline in product costs.

##### Table of Contents

Our research and development expenses increased 4% year-over-year to approximately
NT$1,122.5 million (US$35.1 million) in 2009. Salary and benefits decreased 3% year-over-year to approximately NT$477.1 million (US$14.9 million), primarily because of a 3% decrease in the number of employees engaged in research and development
activities. Stock-based compensation increased 61% year-over-year to approximately NT$224.2 million (US$7.0 million), partly attributable to the accelerated vesting of certain soon-to-vest RSUs and cancellation of a small portion of outstanding
RSUs previously granted to employees. Other expenses decreased 6% year-over-year to approximately NT$421.2 million (US$13.2 million), primarily because of less IC tape-out and other project expenses.

Our sales
and marketing expenses increased 7% year-over-year to approximately NT$396.0 million (US$12.4 million) in 2009. Salary and benefits decreased 3% year-over-year to approximately NT$199.9 million (US$6.3 million), primarily because of a 1%
decrease in the number of employees engaged in sales and marketing activities. Stock-based compensation increased 40% year-over-year to approximately NT$77.5 million (US$2.4 million), partly attributable to the accelerated vesting of certain
soon-to-vest RSUs and cancellation of a small portion of outstanding RSUs previously granted to employees. Other sales and marketing expenses increased 10% year-over-year to approximately NT$118.6 million (US$3.7 million) primarily because of

Our general
and administrative expenses decreased 31% year-over-year to approximately NT$464.7 million (US$14.5 million) in 2009. Salary and benefits decreased 18% year-over-year to approximately NT$174.6 million (US$5.5 million), primarily because of
8% decrease in the number of employees engaged in general and administrative activities. Stock-based compensation increased 71% year-over-year to approximately NT$120.3 million (US$3.8 million), partly attributable to the accelerated vesting of
certain soon-to-vest RSUs and cancellation of a small portion of outstanding RSUs previously granted to employees. Other general and administrative expenses decreased 57% year-over-year to approximately NT$169.8 million (US$5.3 million)
primarily because reserves for doubtful accounts decreased NT$121.6 million (US$3.8 million) and the legal expenses relating to the SanDisk litigation decreased NT$51 million (US$1.6 million) in 2009.

In 2009, we accelerated
the vesting of certain soon-to-vest RSUs and cancelled a small portion of outstanding RSUs previously granted to employees. Total expense incurred for the acceleration and cancellation, net of forfeiture adjustment was approximately NT$163.8
million (US$5.1 million).

Our
amortization of intangible asset decreased 1% year-over-year to approximately NT$192.4 million (US$6.0 million) in 2009. This expense was associated with the amortization of intangible assets relating to our acquisitions of FCI and Centronix in
April and November 2007, respectively.

Impairment of goodwill and long-lived assets.

We performed annual impairment assessments of the carrying value of goodwill and other long-lived assets in November 2009 and 2008. During
our 2009 evaluation, we compared the carrying value of our mobile communications reporting unit to its estimated fair value and determined that goodwill and certain other long-lived assets were impaired and recognized approximately NT$1,019.4
million (US$31.9 million) for goodwill impairment and NT$217.2 million (US$6.8 million) for impairment of certain other long-lived assets.

See Note 11 of Notes to Consolidated Financial Statements for a further discussion of impairment of goodwill and other long-lived assets.

Interest expense. Our interest expense decreased to approximately NT$3.5 million (US$0.1 million) for the year ended
December 31, 2009 from approximately NT$4.8 million for the year ended December 31, 2008 due to less of borrowings in 2009 compared with 2008.

Foreign exchange gain (loss). For the year ended December 31, 2009, we incurred a foreign exchange losses of NT$88.9 million
(US$2.8 million), compared with a gain of NT$96.4 million for the year ended December 31, 2008. The foreign exchange loss in 2009 resulted primarily from the strength of the NT dollar relative to the U.S. dollar.

Interest income. Our interest income decreased to approximately NT$22.1 million
(US$0.7 million) for the year ended December 31, 2009 from approximately NT$44.0 million for the year ended December 31, 2008 because of declining interest rates.

Impairment of long-term investment. In 2009, we determined that our investment in Vastview was impaired because a combination of
recurring losses and reduced forecasts indicated that our investment was not recoverable within a reasonable period of time and that the impairment was other than temporary and recorded an impairment charge of NT$8.6 million (US$0.3 million). In
2008, we determined that our investments in Spright and Vastview were impaired NT$69.3 million.

Income tax expense.
Our income tax expense decreased to approximately NT$6.8 million (US$0.2 million) for the year ended December 31, 2009 from an income tax expense of approximately NT$86.6 million for the year ended December 31, 2008 primarily because of
lower taxable income in 2009.

Net income (loss). Net loss was approximately NT$2,309.2 thousand (US$72.3 million) for
the year ended December 31, 2009, compared to a net income of approximately NT$293.4 million for the year ended December 31, 2008.

Our net sales
for the year ended December 31, 2008 were approximately NT$5,528.1 million compared to approximately NT$5,847.3 million for the year ended December 31, 2007, a decrease of approximately 6%.

Total unit shipment of our products, on the other hand, increased 30%, from 297.2 million units for the year ended
December 31, 2007 to 390.8 million units for the year ended December 31, 2008 because of strong mobile storage and mobile communications unit sales.

Although mobile storage unit sales increased 32% because of strong USB flash drive controller and flash memory card controller
sales, rapid 27% average selling price (ASP) degradation lead to an overall 9% mobile storage product revenue decline, from NT$4,500.1 million for the year ended December 31, 2007 to NT$4,133.8 million for the year ended
December 31, 2008. Multimedia SoCs product revenue fell 29% from NT$563.7 million for the year ended December 31, 2007 to NT$402.1 million for the year ended December 31, 2008 largely because of weak MP3
sales. Declining mobile storage and multimedia SoCs revenue negatively offset a 27% increase in mobile communications revenue, from NT$761.6 million for the year ended December 31, 2008 to NT$965.1 million, which was caused by a doubling
of mobile TV IC solutions sales revenue.

Our cost of
sales grew to approximately NT$2,914.6 million for the year ended December 31, 2008 from approximately NT$2,757.1 million in 2007. Our gross margin decreased to 47% for the year ended December 31, 2008 from 53% for the year ended
December 31, 2007 as a result of mobile storage ASPs declining faster than reductions in cost of sales and larger reserves for obsolete inventory.

Our research and
development expenses increased to approximately NT$1,080.9 million, or 20% of net sales, for the year ended December 31, 2008 from approximately NT$822.7 million, or 14% of net sales, for the year ended December 31, 2007. Several factors
contributed to the 31% increase in research and development expenses. Salary, benefits and compensation expenses were NT$631.8 million in 2008 and increased 29% year-over-year largely because we increased our headcount from 320 to 374 employees in
our research and development group. Also, IC tape-outs and other project expenses increased as we continued to invest in all our product lines.

contributed to the 77% increase in general and administrative expenses. We incurred NT$157.0 million of reserves for doubtful accounts for the year ended December 31, 2008, a significantly higher amount than for the year ended December 31,
2007. Salary, benefits, rental and compensation expenses increased NT$50.0 million largely because we increased our headcount from 93 to 108 employees in our general and administrative group. We also incurred NT$73.0 million of legal expenses
relating to the SanDisk litigation.

Our expense relating to
amortization of intangible assets increased to approximately NT$193.8 million. This expense was associated with the amortization of intangible assets relating to our acquisition of FCI and Centronix in April and November 2007, respectively.

Write-off of in-process research and development. The charge for write-off of in-process research and development was
zero for the year ended December 31, 2008, compared to NT$76.4 million for the year ended December 31, 2007. In-process research and development (IPR&D) expenses were incurred from our FCI acquisition in 2007 and relate to
R&D that have not demonstrated technological feasibility and that do not have alternative future uses.

Gain on sales of long-term investments. In August 2007, we sold all of our investment
in Chipmast and recognized a realized investment gain of NT$5.0 million. No disposals of long-term investments occurred for the year ended December 31, 2008.

Interest expense. Our interest expense increased to approximately NT$4.8 million for the year ended December 31, 2008 from
approximately NT$1.1 million for the year ended December 31, 2007. Our interest expense increased due to increased borrowings in 2008 compared with 2007.

Foreign exchange gain (loss). For the year ended December 31, 2008, we incurred a foreign exchange gain of NT$96.4 million,
compared with a losses of NT$18.7 million for the year ended December 31, 2007. The foreign exchange gain is resulted primarily from the weakening of the NT dollar relative to the U.S. dollar.

Interest income. Our interest income decreased to approximately NT$44 million for the year ended December 31, 2008 from
approximately NT$52.4 million for the year ended December 31, 2007. Our interest income decreased as a result of decreases in our cash and cash equivalent position as well as declining interest rates.

Impairment of long-term investment. In 2007 and 2008, we determined that our investments in Spright and Vastview were impaired.
Because of a combination of recurring losses and reduced forecasts of the investee companies indicated that our investments were not recoverable within a reasonable period of time, we determined for the year ended December, 31, 2007 and 2008 the
impairment for the two investments to be other than temporary and recorded impairment charges of NT$14.4 million and NT$69.3 million for Spright and Vastview, respectively.

Income tax expense. Our income tax expense increased to approximately NT$86.6 million for the year ended December 31, 2008
from an income tax expense of approximately NT$81.6 million for the year ended December 31, 2007. Our income tax expense increased as a result of tax examination by foreign jurisdictions and recognition of additional valuation allowance for
deferred income tax assets not expected to be realized.

Net income. Net income decreased to approximately NT$293.4
thousand for the year ended December 31, 2008 from approximately NT$1,312.5 million for the year ended December 31, 2007.

Liquidity and Capital Resources

As of December 31, 2009, we had approximately NT$1,951.6 million (US$61.1 million) in cash and cash equivalents and approximately
NT$21.2 million (US$0.7 million) in short-term investments. We maintain our cash balances in bank deposits and in money market instruments. Our short-term investments consist primarily of bond funds that we trade and which invest primarily in Taiwan
government and Taiwan investment grade corporate bonds.

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 and availability of attractive acquisition opportunities. 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.

Operating activities

Operating activities generated cash of NT$323.9 million (US$10.1 million), NT$2,785 million and NT$1,599.3 million during 2009, 2008 and
2007, respectively.

For the year ended December 31, 2009, cash flow from operations of NT$323.9 million (US$10.1
million) resulted primarily from our net loss of NT$2,309.2 million (US$72.3 million) and the following reasons:



| |  |  | Our net loss includes substantial non-cash charges, namely NT$355.5 million (US$11.1 million) of depreciation and amortization, NT$446.5
million (US$14.0 million) of stock-based compensation, and NT$1,245.2 million (US$39.0 million) of loss on impairment of assets.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our proceeds from sale of short-term investments net of purchase of short term investments were NT$91.6 million (US$2.9 million).

We recognized additional long-term taxes payable of NT$16,192 thousand (US$507 thousand) related to uncertain tax positions as of
December 31, 2009. At this time, we are unable to make a reasonably reliable estimate of the timing of payments in individual years beyond 12 months due to uncertainties in the timing of tax audit outcomes.

Off-balance Sheet Arrangements

We currently do not have any outstanding derivative financial instruments, off-balance sheet guarantees or arrangements, interest rate
swap transactions, or foreign currency forward contracts. We do not engage in any trading activities involving non-exchange traded contracts.

Recent Accounting Pronouncements

In December 2008, the Financial Accounting Standards Board (FASB) issued accounting standards relating to the disclosure
requirements for defined benefit plans, which provide guidance on an employers disclosures about plan assets of a defined benefit pension or other postretirement plan. The new accounting standards are effective for annual reporting periods
ending after December 15, 2009. The Company has adopted the standards effective for its December 31, 2009 annual report on Form 20-F. However, information on how investment allocation decisions are made, inputs and valuation techniques
used to measure the fair value of plan

##### Table of Contents

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 companies by the government. Therefore, the Company is unable to provide the required fair value disclosures related to pension plan assets.

In April 2009, the FASB issued a standard that provides additional guidance for estimating fair value when the volume and level of
activity for an asset or liability have significantly decreased. It also included guidance on identifying circumstances that indicate a transaction is not orderly. This guidance is effective for interim and annual reporting periods ending after
June 15, 2009, and should be applied prospectively. This standard is effective for the Company for the year ending December 31, 2009. The adoption of the guidance did not have a material effect on the Companys results of operations,
financial position and cash flows.

In April 2009, the FASB issued a standard that provides guidance on the recognition and
presentation of other-than-temporary impairments of debt securities classified as available-for-sale and held-to-maturity. This standard is effective for interim and annual reporting periods ending after June 15, 2009. This guidance is
effective for the Company for the year ending December 31, 2009. The adoption of the guidance did not have any impact on the Companys results of operations, financial position and cash flows.

In May 2009 and subsequently updated in February 2010, the FASB issued new guidance on subsequent events that establishes general
standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. This standard defines two types of subsequent events, recognized or nonrecognized. The new guidance is effective
for the Company for the year ending December 31, 2009.

In June 2009, the FASB issued new guidance relating to the
transfer of financial assets. The new guidance requires entities to provide more information regarding sales of securitized financial assets and similar transactions, particularly if the entity has continuing exposure to the risks related to
transferred financial assets. It also eliminates the concept of a qualifying special-purpose entity, changes the requirements for derecognizing financial assets and requires additional disclosures. The new guidance becomes effective for
annual reporting periods beginning after November 15, 2009. Based on the Companys analysis, the Company currently does not anticipate that the new guidance will have a material effect on the Companys results of operations and
financial position or cash flows.

In June 2009, the FASB issued new guidance to improve financial reporting by enterprises
involved with variable interest entities (VIE). The new guidance modifies the approach for determining the primary beneficiary of a VIE. Under the modified approach, an enterprise is required to make a qualitative assessment whether it
has (1) the power to direct the activities of the VIE that most significantly impact the entitys economic performance and (2) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could
potentially be significant to the VIE. If an enterprise has both of these characteristics, the enterprise is considered the primary beneficiary and must consolidate the VIE. The new guidance becomes effective for annual reporting periods beginning
after November 15, 2009. Based on the Companys analysis, the Company currently does not anticipate that the new guidance will have a material effect on the Companys results of operations and financial position or cash flows.

In June 2009, the FASB issued its Accounting Standards Codification (ASC) 105, which became the source of
authoritative U.S. GAAP recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal securities law are also sources of authoritative U.S. GAAP for SEC registrants. The ASC
became effective for the financial statements issued for interim and annual periods ending after September 15, 2009 and superseded all then-existing non-SEC accounting and reporting standards. All other non-grandfathered non-SEC accounting
literature not included in the ASC will become nonauthoritative. The FASB will not issue new standards in the form of Statements (SFASs), FASB Staff Positions (FSPs) or Emerging Issues Task Force Abstracts
(EITFs), but rather it will issue Accounting

##### Table of Contents

Standards Updates (ASUs). FASB will not consider the ASUs as authoritative in their own right as they will only serve to update the ASC, provide background information about
guidance and provide the bases for conclusions on the changes in the ASC. The Company has adopted the ASC effective for its December 31, 2009 annual report on Form 20-F and has revised the disclosure of the U.S. GAAP source references in its
financial reporting upon such adoption.

In September 2009, the FASB issued an accounting standard update which provides
guidance on how to separate consideration in multiple-deliverable arrangements and significantly expands disclosure requirements. The standard establishes a hierarchy for determining the selling price of a deliverable eliminates the residual method
of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. The update is effective for annual reporting periods beginning on or after
June 15, 2010. Based on the Companys analysis, the Company currently does not anticipate that the new guidance will have a material effect on the Companys results of operations and financial position or cash flows.

In September 2009, the FASB issued an accounting standard update on arrangements that include software elements. Tangible products that
have software components that are essential to the functionality of the tangible product will no longer be within the scope of the software revenue recognition guidance, and software-enabled products will now be subject to other relevant revenue
recognition guidance. The update is effective for annual reporting periods beginning on or after June 15, 2010. Based on the Companys analysis, the Company currently does not anticipate that the new guidance will have a material effect on
the Companys results of operations and financial position or cash flows.

In January 2010, the FASB issued amended
standards that require additional fair value disclosures. These amended standards require disclosures about inputs and valuation techniques used to measure fair value as well as disclosures about significant transfers, beginning in the first quarter
of 2010. Additionally, these amended standards require presentation of disaggregated activity within the reconciliation for fair value measurements using significant unobservable inputs (Level 3), beginning in the first quarter of 2011. The Company
does not expect these new standards to significantly impact the consolidated financial statements.

Trend Information

The dislocations from the recent economic recession continued to affect our business in 2009. The supply of NAND flash components declined
in 2009 as NAND flash manufacturers reduced their output of NAND flash wafers and components. Additionally, the reduced supply of NAND flash components available to manufacturers of flash memory cards and USB flash drives was further reduced
because of strong demand for NAND flash by smartphone OEMs for use as memory embedded in their devices. Consequently, our customers purchased less NAND flash components, manufactured fewer flash memory cards and USB flash drives and procured fewer
controllers from us. Demand for our mobile communications ICs and multimedia SoCs, our other products, were affected by weak consumer demand in Korea, Japan, and other end-markets.

We believe that in 2010, global economic conditions will likely begin recovering and our business will also gradually recover. We
expect that in 2010, NAND flash component supply to our customers will increase and consumer confidence will improve.

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. One of our seven directors is currently subject to reelection at our next annual general
meeting of shareholders. All of our executive officers are appointed by and serve at the discretion of our board of directors.

Limitation
on Liability and Other Indemnification Matters

Cayman Islands law and our articles of association allow us to indemnify
our directors, secretary and other officers acting in relation to any of our affairs against actions, costs, charges, losses, damages and expenses incurred by reason of any act done or omitted in the execution of their duties as our directors,
secretary and other officers. 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, 2009, the aggregate compensation to our directors and senior executive officers was approximately
NT$52.01million (US$1.57 million). In 2009, we granted restricted stock units to our

executive officers as a group to acquire an aggregate of 2,382,000 ordinary shares. The restricted stock units granted to our executive officers and non-executive directors are subject to the
same vesting conditions as 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 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 Plan to increase the authorized shares available for issuance under the Plan to 40,000,000 shares. The 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 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 Plan will not
exceed 40,000,000 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 Plan may
again become available for the grant of new awards under the Plan: restricted stock issued under the Plan 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 Plan that have expired or otherwise terminated without having been exercised in full.

Administration. The board of directors will administer the Plan and may delegate this authority to administer the plan to a
committee. Subject to the terms of the Plan, 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 Plan 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 2005 Incentive Plan 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 Plan in 2009. In 2009, our board of directors amended the 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 the Nasdaq Marketplace Rules to effect such amendments without a shareholder vote. In 2009, the Company cancelled 1,221,875 RSUs. There were no amendments to outstanding options in 2009.

Future amendments and termination. The board of directors may amend (subject to shareholder approval as required by
applicable law), suspend or terminate the Plan at any time. Unless sooner terminated by the board of directors, the Plan will terminate pursuant to its terms on April 22, 2015.

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 116,904,172 of our ordinary shares outstanding as of May 31, 2010. The following table sets forth
information with respect to the beneficial ownership of our ordinary shares as of May 31, 2010, unless otherwise indicated in the footnotes, by:

Major Shareholders

As of May 31, 2010, there were 116,904,172 of our ordinary shares outstanding. The Bank of New York Mellon, the depositary under our
ADS deposit agreement, has advised us that as of May 31, 2010, we had 28,974,588 ADSs, representing 115,898,352 ordinary shares.

The table in Item 6 above includes information known to us regarding those shareholders that beneficially own 5% or more of our
ordinary shares. To our knowledge, we are not owned or controlled, directly or indirectly, by another corporation, by any foreign government or by any other natural or legal persons, severally or jointly. We are not aware of any arrangement which
may at a later date result in a change of control of our company.

No holder of our ordinary shares has preferential voting
rights.

Related Party Transactions

Future Communications Incorporated (FCI), the Companys subsidiary in South Korea offers its employees a program through
SC First Bank whereby the employee is able to borrow money from the bank and FCI in turn deposits with the bank the amount of the loan which becomes restricted cash supporting the loan in case of default. In 2008, one of the Companys
employees who, on July 1, 2008 became an executive officer, participated in this program. The largest amount outstanding under such executive officers loan in 2008 was NT$773.6 thousand (US$23.6 thousand). The employee officer
is no longer participating in this program.

Legal Proceedings

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 a material adverse effect on our business, financial position, results of operations or cash flows.

On May 1, 2005, SMI Taiwan incurred a loss on inventory in the possession of a subcontractor, Advanced Semiconductor Engineering
Inc. (ASE) due to a fire. On December 12, 2005, SMI Taiwan filed an action against ASE with the Taiwan Taoyuan District Court. SMI Taiwan alleged that ASE destroyed the wafers which SMI Taiwan had sub-contracted to ASE with the OEM
Agreement between SMI and ASE, and that ASE should pay SMI Taiwan a sum of NT$77,218 thousand for damages, an amount exceeding the book value of lost inventory. After consultation with the Companys outside legal counsel, the Company believed
it was highly probable for the Company to receive reimbursement for the lost inventory at full book value, and the Company subsequently recorded NT$41,226 thousand of inventory loss, offset by NT$41,226 thousand of fire loss reimbursement, resulting
in zero impact to the earnings for the period. In connection with the inventory loss, the Company also recorded NT$8,122 thousand under non-operating expenses for amounts paid to certain customers for delays in shipments caused by the fire. In April
2010, ASE settled with SMI Taiwan by paying a settlement fee NT$35,000 thousand. On April 28, 2010, the Taiwan Taoyuan District Court granted a motion to dismiss the claim filed by SMI Taiwan against ASE.

On October 23, 2007, SanDisk Corp. (SanDisk) filed a complaint with the
United States International Trade Commission (ITC) against multiple respondents, including Silicon Motion Technology Corp., SMI Taiwan and SMI USA (in aggregate Silicon Motion). SanDisk claimed that certain Silicon Motion
flash memory controllers and products containing these Silicon Motion flash memory controllers infringed specific SanDisk patents. The complaint requested the ITC institute an investigation into the matter and sought a permanent exclusion order to
exclude from entry into the United States all flash memory controllers and products containing controllers that infringe any of the asserted patents. The complaint also sought a permanent cease and desist order, directing respondents to cease and
desist from marketing, advertising, demonstrating, sampling, warehousing inventory for distribution, offering for sale, selling, distributing, licensing, or using any flash memory controllers and products containing flash controllers that infringe
any of the asserted patents. On December 6, 2007, the ITC instituted an investigation, identifying forty-seven companies, including Silicon Motion, as respondents. An ITC hearing was held as scheduled from October 27 through
November 5, 2008. In post-hearing briefing, the Office of Unfair Import Investigation (OUII) Staff Attorney agreed with our position that none of the Silicon Motion controllers infringed the SanDisk patents in suit. On
April 10, 2009, the Administrative Judge of the ITC issued an initial determination that Silicon Motion flash controllers and products containing these Silicon Motion flash controllers did not infringe the patents of SanDisk. On
October 23, 2009, the ITC determined that Silicon Motion was not in violation of Section 337 of the Tariff Act of 1930 and terminated its investigation.

On October 24, 2007, SanDisk filed two complaints, for alleged patent infringement against multiple defendants, including Silicon
Motion in the United States District Court for the Western District of Wisconsin. The complaints alleged that Silicon Motions flash memory controllers infringed certain SanDisk patents and sought unspecified damages, injunctive relief, a
trebling of damages for alleged willful conduct and attorneys fees. Both cases were stayed until SanDisks ITC proceeding became final. SanDisk entered into a settlement with Silicon Motion and no settlement payments were required from
Silicon Motion. On February 4, 2010, the Court ordered the dismissal of SanDisks claims against Silicon Motion without prejudice pursuant to SanDisks requests.

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 in the bankruptcy case pending in the U.S. Bankruptcy Court for the Southern District of
Florida. The AASI Creditor Liquidating Trust was seeking the return of allegedly avoidable transfers in the amount of NT$27,977 thousand (US$854 thousand). The Company filed an answer and affirmative defenses. In March 2010, SMI USA
settled with the AASI Creditor Liquidating Trust by paying the amount of US$220,000, of which US$65 thousand was accrued for as of December 31, 2009, and on April 1, 2010, the Bankruptcy Court granted the motion to approve stipulations to
compromise controversy.

On September 11, 2009, FCI filed a claim against Automobile & PCB Inc.
(ANP) for losses caused by the sale of products using substandard PCB substrates supplied by this vendor. At the time of FCIs procurement of the PCB substrates and prior to a change of name in February 2009, ANP was known as
Quality & Technology Korea Inc. (Q&Tec). FCI is claiming approximately US$500 thousand in losses from ANP for material, assembly, testing, and validation costs. The claim was filed at the Seongnam Municipal Court
in Koreas Gyeonggi Province and judgment is expected to be delivered by the court in mid-2010.

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;
| | - |  | ------



| |  |  | dealers in securities or currencies; financial institutions; insurance companies; tax-exempt organizations;
| | - |  | -----------------------------------------------------------------------------------------------------------



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



| |  |  | traders in securities that have elected the mark-to-market method of accounting;
| | - |  | --------------------------------------------------------------------------------



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



| |  |  | U.S. persons whose functional currency is not the U.S. dollar; or
| | - |  | -------------------------------------------------------------------



| |  |  | 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, 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. This discussion does not
attempt to address the consequences to holders of shares or ADSs who acquired their shares or ADSs through the exercise of an employee stock option or otherwise as compensation or through a tax-qualified retirement plan.

A U.S. Holder 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;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | 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 and
provided that such holder satisfies certain holding period requirements with respect to the ownership of our ADSs, or ordinary shares. The reduced rate of tax applicable to dividends from a qualified foreign corporation does not apply to
taxable years beginning after December 31, 2010. Subject to the exceptions discussed below, a qualified foreign corporation includes:



| |  |  | 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; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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 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, 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.

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



56



---

##### Table of Contents

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.

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 are not currently and, should
not in the future, be classified as a passive foreign investment company for U.S. federal income tax purposes, 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. In
addition, the composition of our income and assets will be affected by how we spend the cash we raise in this offering. 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.

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



57



---

##### Table of Contents

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 National 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 a U.S. Holder owns ADSs or ordinary shares during any year that we are a passive foreign investment company, the U.S. Holder must file
Internal Revenue Service Form 8621.

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 market-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.

Documents on Display

We have previously filed with the SEC our registration statement on Form F-1 and 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 six 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.

Copies of reports and other information, when so filed, may be inspected without charge and may be obtained at prescribed rates at the
public reference facilities maintained by the Securities and Exchange Commission at the SECs public reference room in Washington D.C. at 100 F Street, N.E., Room 1580, Washington D.C. 20549. You can request copies of these documents upon
payment of a duplicating fee, by writing to the SEC. Please call the SEC at 1-800-SEC-0330 for further information on the operation of the public reference rooms. The SEC also maintains a Website at www.sec.gov that contains reports, proxy and
information statements, and other information regarding registrants that make electronic filings with the SEC using its EDGAR system.



|ITEM11. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- | ----------------------------------------------------------

Interest rate risk. Our exposure to interest risk for changes in interest rates is limited to the
interest income generated by our cash deposited with banks and short-term investments maintained in bond funds. We do not believe that a 1% change in interest rates would have a significant impact on our operations.

Foreign currency risk. Although a majority of our revenues and expenses are denominated in U.S. dollars, our operational
headquarters are in Taiwan and we report our financial results in NT dollars. We are therefore exposed to adverse and beneficial movements in foreign currency rates, which results in foreign exchange gains or losses that affect our results of
operations. For the year ended December 31, 2007, 2008 and 2009, we had foreign exchange losses of NT$18.7 million, foreign exchange gains NT$96.4 million, and foreign exchange losses NT$88.9 million (US$2.8 million), respectively. As of
December 31, 2009, more than 96% of our accounts payable and other payables were denominated in currencies other than the NT dollar, primarily in U.S. dollars. More than 92% of our accounts receivable were denominated in currencies other than
the NT dollar, mainly in U.S. dollars. In 2009, most of our sales were quoted in U.S. dollars and approximately 13% of our sales quotes were invoiced in NT dollars using the opening average exchange rate on the day of the sales invoice. In 2009,
approximately 52% of our cost of sales and operating expenses were denominated in U.S. dollars. Hypothetically, if the U.S. dollar value had increased or decreased by 10% against the NT dollar in 2009, our operating income would have increased or
decreased, as the case may be, by approximately 12%, assuming all other factors remain constant. We anticipate that we will continue to quote substantially most of our sales in U.S. dollars. We do not utilize foreign exchange derivatives contracts
to protect against the volatility changes in foreign exchange rates. See Risk Factors  We are subject to risks associated with international operations which may harm our business.

Investment Risk.Prior to 2000, we invested in equity instruments of privately held companies. We have minority stake equity
investments in Cashido, Spright and Vastview Technology, private companies related to 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. As of December 31, 2009, the aggregate carrying value of these investments on our balance sheet was NT$15.7 million (US$0.5 million). The carrying value of
these investments in private companies is subject to fluctuation based on many factors such as prevailing market conditions. We monitor

these investments for impairment and make appropriate reductions in carrying value when an impairment is deemed to be other than temporary. We have experienced declines in the value of certain
investments and recorded impairment loss of NT$14.4 million, NT$69.3 million, and NT$8.6 million US$0.3million) in 2007, 2008 and 2009, respectively.

As of December 31, 2009, we also had NT$21.2 million (US$0.7 million) of short-term investments in bond funds that invest in Taiwan
government and Taiwan investment grade corporate bonds.



|ITEM12. | DESCRIPTION OF SECURITIES OTHER THAN EQUITY SECURITIES
|------- | ------------------------------------------------------

Depositary Fees and Charges.For the year-ended December 31, 2009, we received from the depositary a
reimbursement of US$0.3 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 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.

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, 2009. 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 in a timely manner. 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 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, 2009 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 on our managements assessment of our control over financial report.

Changes in Internal Control over Financial Reporting

During 2009, 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 Board of Directors and Shareholders of

Silicon Motion Technology Corporation

We have audited the internal control over financial reporting of Silicon Motion Technology Corporation and subsidiaries (the
Company) as of December 31, 2009, based on criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. 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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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.

A companys
internal control over financial reporting is a process designed by, or under the supervision of, the companys principal executive and principal financial officers, or persons performing similar functions, and effected by the companys
board of directors, management, and other personnel 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 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.
Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects,
effective internal control over financial reporting as of December 31, 2009 based on the criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the
consolidated financial statements as of and for the year ended December 31, 2009 of the Company and our report dated June 17, 2010 expressed an unqualified opinion on those financial statements.

Our audit committee is responsible for the retention of our independent registered public accounting firm, which currently is
Deloitte & Touche. Our audit committee has adopted its own rules of procedure, in the form of an audit committee charter. The audit committees rules of procedure provide for a process with respect to the prior approval of all
non-audit services to be performed by our independent auditors. Our audit committee reports to our board of directors regarding the scope and results of our annual audits, compliance with our accounting and financial policies and managements
procedures and policies related to the adequacy of our internal accounting controls.

In 2009 our audit committee approved all
of the audit services provided by Deloitte & Touche, and the other services provided by Deloitte & Touche.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Silicon Motion Technology Corporation

We have audited the accompanying consolidated balance sheets of Silicon Motion Technology Corporation and subsidiaries (the
Company) as of December 31, 2009 and 2008, and the related consolidated statements of income, changes in shareholders equity, and cash flows for each of the three years in the period ended December 31, 2009, all expressed
in New Taiwan dollars. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of the Company as of December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2009, in conformity with
accounting principles generally accepted in the United States of America.

Our audits also comprehended the translation of New
Taiwan dollar amounts into U.S. dollar amounts and, in our opinion, such translation has been made in conformity with the basis stated in Note 3 to the consolidated financial statements. Such U.S. dollar amounts are presented for the convenience of
the readers in the United States of America.

We have also audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the Companys internal control over financial reporting as of December 31, 2009, based on the criteria established in Internal Control  Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission and our report dated June 17, 2010 expressed an unqualified opinion on the Companys internal control over financial reporting.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States
of America (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, except for FCI which the Company owns 99.91%.
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

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents, investment
in debt securities and accounts receivable. Cash are deposited with high credit-quality financial institutions. For accounts receivable, the Company performs ongoing credit evaluations of its customers financial condition and the Company
maintains an allowance for doubtful accounts receivable based upon a review of the expected collectibility of individual accounts.

The Companys direct and indirect customers include major OEMs and ODMs of flash memory-based storage products mobile phones and
other electronics devices. Many of the Companys customers sell brand name consumer electronics products that include the Companys products. For mobile storage products, the Companys worldwide customers include companies such as
Hynix, Kingston, Lexar Media, Samsung, Sony and

Transcend. For the multimedia products, the Companys worldwide customers include Advantech, AsusTek, ChipPC, Fuji-Xerox, Kontron, Lenovo, Siemens, ThinNetworks, and Toshiba-TEC. For mobile
communication, the Companys worldwide customers include LG Electronics, Pantech, and Samsung. For the years ended December 31, 2007, 2008 and 2009, only one of the Companys customers individually accounted for greater than 10% of
net sales. The Companys top ten customers in 2007, 2008 and 2009 accounted for approximately 57%, 52% and 54% of net sales.

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 and long-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. The Companys long-term liabilities approximate their fair values as they contain interest rates that vary according to market interest rates.

On January 1, 2008, the Company adopted ASC 820 Fair Value Measurements and Disclosures, which defines fair value,
establishes a framework for measuring fair value and expands disclosures about fair value measurements.

ASC 820 defines fair
value as 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 asset 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.

In addition to defining fair value, ASC 820 expands the disclosure requirements around fair value and establishes a fair value hierarchy
for valuation inputs. 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 19, Fair Value Measurement, for the related disclosure.

Cash Equivalents

The Company considers all highly liquid investments with maturities within three months from the date of purchase to be cash equivalents.

Short-term Investments

The Company invests its excess cash in bond funds and uses the average cost method when determining their cost basis. Marketable
securities that are bought and held principally for the purpose of selling them in near term are classified as trading securities and are initially recognized at fair value, with subsequent changes in fair value recorded in earnings as unrealized
gains and losses.

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, finished goods and work in process. 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

Long-term investments wherein the Company does not exercise significant influence are accounted for under the cost method of accounting.
Management evaluates related information (e.g., budgets, business plans, financial statements, etc.) in determining whether an other than temporary decline in 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.

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. Depreciation expense recognized for the years ended December 31, 2007, 2008 and 2009 was approximately NT$92,284 thousand, NT$155,225 thousand and NT$163,129
thousand (US$ 5,106 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. 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 core technology, customer relationship and order backlog, are amortized over their estimated useful lives, ranging from 3 months to 4 years at the time of acquisition.

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 Intangible Assets, regarding impairment in fiscal year 2009.

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 conducted its annual impairment test of goodwill as of November 30, 2009. Reporting units may be operating segments as a whole or an
operation one level below an operating segment, referred to as a component. 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
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. 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 the Companys market capitalization plus control premium for reasonableness. See Note 11, Goodwill and Intangible Assets, regarding impairment in fiscal year 2009.

Other Assets

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

Restricted Assets

Restricted assets consist of deposits required for litigation and 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.

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

Revenue from product sales is generally recognized upon shipment to the customer provided that the Company has received a signed purchase
order, the price is fixed or determinable, transfer of title has occurred in accordance with the shipping terms specified in the arrangement with the customer, collectibility from the customer is considered reasonably assured, product returns are
reasonably estimable and there are no remaining significant obligations or customer acceptance requirements.

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. A reserve for price adjustments is recorded based on the estimated products on hand at the distributors and historical experience. The Company incurred actual price adjustments to distributors of NT$74 thousand, NT$6 thousand
and NT$381 thousand (US$12 thousand) in 2007, 2008 and 2009.

The Company provides a warranty period of one year 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, 2007, 2008 and 2009, the Company did not experience significant costs associated with warranty returns.

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 the 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.

Effective January 1, 2007, the Company adopted standards that clarified the accounting for uncertain tax
positions. The new standards provide that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation
processes, based on the technical merits. Income tax positions must meet a more-likely-than-not recognition threshold at the effective date to be recognized upon the adoption of the new standards and in subsequent periods. The new standards also
provide guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company decreased deferred income tax assets and reduced retained earnings by NT$12,000 thousand in
connection with its adoption. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense. See Note 14, Income Taxes, for further discussion of the effects of adoption.

Under Taiwan tax regulations, the current years earnings, on an after tax basis, that are not distributed in the following year are
subject to a 10% additional income tax. This 10% additional income tax is recognized in the period during which the related earnings are generated.

The R.O.C. government enacted the Alternative Minimum Tax Act (the AMT Act), which became effective on January 1, 2006.
The alternative minimum tax (AMT) imposed under the AMT Act is a supplemental tax levied at a rate of 10% which is payable if the income tax payable determined pursuant to the Income Tax Law is below the minimum amount prescribed under
the AMT Act. The taxable income for calculating the AMT includes most of the income that is exempted from income tax under various laws and statutes. The Company has considered the impact of the AMT Act in the determination of its tax liabilities.

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 New Taiwan dollar. The functional currency of each one of the Companys subsidiaries is
the local currency of the respective entity. Accordingly, the financial statements of the foreign subsidiaries are translated into New Taiwan 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 shareholders equity in accumulated other comprehensive
income.

Legal Contingencies

The Company is currently 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 (Loss) Per Share

Basic earnings (loss) per share are computed by dividing net earnings (loss) 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.

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 and recognizes compensation expense on a straight-line basis over the requisite service period of the award.

Treasury Stock

Treasury stock is stated at cost and shown as a reduction to shareholders equity.

The Company retires ordinary shares repurchased under a share repurchase plan. Accordingly, upon retirement the excess of the purchase
price over par value is allocated between additional paid-in capital and retained earnings based on the average issuance price of the shares repurchased. A repurchase of ADSs is recorded as treasury stock until the Company completes the withdrawal
of the underlying ordinary shares from the ADS program.

Recent Accounting Pronouncements

In December 2008, the Financial Accounting Standards Board (FASB) issued accounting standards relating to the disclosure
requirements for defined benefit plans, which provide guidance on an employers disclosures about plan assets of a defined benefit pension or other postretirement plan. The new accounting standards are effective for annual reporting periods
ending after December 15, 2009. The Company has adopted the standards effective for its December 31, 2009 annual report on Form 20-F. 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 companies by the government. Therefore, the Company is unable to provide the required fair value disclosures related to pension plan assets. See Note 13, Pension Plan.

In April 2009, the FASB issued a standard that provides additional guidance for estimating fair value when the volume and level of
activity for an asset or liability have significantly decreased. It also included guidance on identifying circumstances that indicate a transaction is not orderly. This guidance is effective for interim and annual reporting periods ending after
June 15, 2009, and should be applied prospectively. This standard is effective for the Company for the year ending December 31, 2009. The adoption of the guidance did not have a material effect on the Companys results of operations,
financial position and cash flows.

In April 2009, the FASB issued a standard that provides guidance on the recognition and
presentation of other-than-temporary impairments of debt securities classified as available-for-sale and held-to-maturity. This standard is effective for interim and annual reporting periods ending after June 15, 2009. This guidance is
effective for the Company for the year ending December 31, 2009. The adoption of the guidance did not have any impact on the Companys results of operations, financial position and cash flows.

In May 2009 and subsequently updated in February 2010, the FASB issued new guidance on subsequent events that establishes general
standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. This standard defines two types of subsequent events, recognized or non-recognized. The new guidance is
effective for the Company for the year ending December 31, 2009.

In June 2009, the FASB issued new guidance relating to
the transfer of financial assets. The new guidance requires entities to provide more information regarding sales of securitized financial assets and similar transactions, particularly if the entity has continuing exposure to the risks related to
transferred financial assets. It

also eliminates the concept of a qualifying special-purpose entity, changes the requirements for derecognizing financial assets and requires additional disclosures. The new guidance
becomes effective for annual reporting periods beginning after November 15, 2009. Based on the Companys analysis, the Company currently does not anticipate that the new guidance will have a material effect on the Companys results of
operations and financial position or cash flows.

In June 2009, the FASB issued new guidance to improve financial reporting by
enterprises involved with variable interest entities (VIE). The new guidance modifies the approach for determining the primary beneficiary of a variable interest entity (VIE). Under the modified approach, an enterprise is required to
make a qualitative assessment whether it has (1) the power to direct the activities of the VIE that most significantly impact the entitys economic performance and (2) the obligation to absorb losses of the VIE or the right to receive
benefits from the VIE that could potentially be significant to the VIE. If an enterprise has both of these characteristics, the enterprise is considered the primary beneficiary and must consolidate the VIE. The new guidance becomes effective for
annual reporting periods beginning after November 15, 2009. Based on the Companys analysis, the Company currently does not anticipate that the new guidance will have a material effect on the Companys results of operations and
financial position or cash flows.

In June 2009, the FASB issued its Accounting Standards Codification (ASC) 105, which became
the source of authoritative U.S. generally accepted accounting principles (U.S. GAAP) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal securities law are also
sources of authoritative U.S. GAAP for SEC registrants. The ASC became effective for the financial statements issued for interim and annual periods ending after September 15, 2009 and superseded all then-existing non-SEC accounting and
reporting standards. All other non-grandfathered non-SEC accounting literature not included in the ASC will become nonauthoritative. The FASB will not issue new standards in the form of Statements (SFASs) FASB Staff Positions (FSPs) or
Emerging Issues Task Force Abstracts (EITFs), but rather it will issue Accounting Standards Updates (ASUs). FASB will not consider the ASUs as authoritative in their own right as they will only serve to update the ASC, provide
background information about guidance and provide the bases for conclusions on the changes in the ASC. The Company has adopted the ASC effective for its December 31, 2009 annual report on Form 20-F and has revised the disclosure of the U.S.
GAAP source references in its financial reporting upon such adoption.

In September 2009, the FASB issued an accounting
standard update which provides guidance on how to separate consideration in multiple-deliverable arrangements and significantly expands disclosure requirements. The standard establishes a hierarchy for determining the selling price of a deliverable,
eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. The update is effective for annual reporting
periods beginning on or after June 15, 2010. Based on the Companys analysis, the Company currently does not anticipate that the new guidance will have a material effect on the Companys results of operations and financial position or
cash flows.

In September 2009, the FASB issued an accounting standard update on arrangements that include software elements.
Tangible products that have software components that are essential to the functionality of the tangible product will no longer be within the scope of the software revenue recognition guidance, and software-enabled products will now be subject to
other relevant revenue recognition guidance. The update is effective for annual reporting periods beginning on or after June 15, 2010. Based on the Companys analysis, the Company currently does not anticipate that the new guidance will
have a material effect on the Companys results of operations and financial position or cash flows.

In January 2010, the FASB issued amended standards that require additional fair value disclosures. These amended standards require
disclosures about inputs and valuation techniques used to measure fair value as well as disclosures about significant transfers, beginning in the first quarter of 2010. Additionally, these amended standards require presentation of disaggregated
activity within the reconciliation for fair value measurements using significant unobservable inputs (Level 3), beginning in the first quarter of 2011. The Company does not expect these new standards to significantly impact the consolidated
financial statements.

3. US DOLLAR AMOUNTS

The Company maintains its accounts and expresses its financial statements in New Taiwan dollars. For convenience only, U.S. dollar amounts
presented in the accompanying financial statements have been translated from New Taiwan dollars, using the U.S. Federal Reserve Bank of New York noon-buying rate of NT$31.95 to US$1 on December 31, 2009. The convenience translations should not
be construed as representations that the New Taiwan dollar amounts have been, could have been or could in the future be, converted into U.S. dollars at this or any other exchange rate.

4. BUSINESS COMBINATIONS

FCI

On April 30, 2007, the Company completed its acquisition of FCI, a leading designer of RF ICs for mobile television and wireless
communications based in Seoul, South Korea.

In exchange for 99.59% of outstanding shares of common stock of FCI and
assumption of all vested and unvested FCI options, the Company issued 6,306 thousand ordinary shares, 370,274 stock options and paid approximately NT$1,659.8 million in cash and incurred transaction costs of approximately NT$61.1 million. The
value of the 6,306 thousand ordinary shares issued was determined based on the average market price of the Companys ordinary shares over the 20-day period before and after the terms of the acquisition were agreed to and announced. In
addition, the Company paid former FCI shareholders an additional US$12 million in cash (Earn-out) on the achievement of certain operating and financial milestones in 2007. The Company also accelerated the vesting of 50% of the options
held by FCI employees when Earn-out targets were met. In accordance with the Share Purchase Agreement, such options became exercisable immediately after announcement of the Companys 2007 earnings results on February 1, 2008. The
incremental compensation cost associated with the accelerated vesting was insignificant.

The total purchase consideration is
summarized as follows:



|                                                          |  |          
|--------------------------------------------------------- |  | ---------

|Value of ordinary shares issued and stock options assumed |  | 1,293,823
|Cash consideration                                        |  | 2,048,991
|Transaction costs                                         |  | 61,051

|Total purchase consideration                              |  | 3,403,865
|                                                          |  |          

The Company issued approximately 370,274 stock options
valued at NT$64,376 thousand in exchange for FCI stock options held by FCIs employees at the closing date. Of the total stock options issued, approximately 277,705 stock options were unvested at the closing date. In accordance with ASC
718, vested stock options or awards issued by an acquirer in exchange for outstanding awards held by employees of the acquiree should be

considered as a part of the purchase price paid by the acquirer for the acquiree in a business combination. Accordingly, the fair value of the new awards of NT$32,394 thousand was included in the
purchase price. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition:



|                                               |  |           |

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



|                                     |  |         |  |

|                                     |  |         |  |            

The core technology represented the existing know-how in IC design for RF receivers including all
the developed and in-process products for the FCI business.

Customer relationships can be identified as intangible assets
when an entity has a practice of establishing contracts with customers, regardless of whether a contract existed at the date of acquisition.

The estimated fair value attributed to order backlog was based on outstanding purchase orders at the date of acquisition.

The estimated fair value of in-process research and development was defined as research and development projects in process at the time
of the transaction that have not demonstrated their technological feasibility and that do not have an alternative future use. The entire amount was written off immediately in the second quarter of 2007. The IPR&D relates to the research and
development of ICs used in mobile TV-related application.

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.

The operating results of FCI have been included in the Companys operations beginning May 1, 2007. The following unaudited pro
forma information represents a summary of the results of operations as if the acquisition occurred on January 1, 2007 and includes certain pro forma adjustments, including amortization of identifiable intangibles and unrecognized compensation

The pro forma
results are based on various assumptions and are not necessarily indicative of what would have occurred had the acquisition closed on January 1, 2007.

Centronix

On November 30, 2007, the Company acquired select parts of the Centronix mobile TV business of Korea information Engineering Services
Co., Ltd. (KIES). This business segment develops and markets products and services related to mobile TV. The aggregate purchase consideration was NT$115,889 thousand in cash. The value of this acquisition did not have a material effect
on the Companys results of operations in 2007 and therefore, its unaudited pro forma results are not presented herein.

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



|                       |  |        
|---------------------- |  | -------

|Total assets acquired  |  | 115,889
|                       |  |        

Intangible assets acquired represented core technology
which has a weighted-average useful life of approximately 4 years.

SILICON MOTION TECHNOLOGY CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)

(In Thousands)



In December 2006 and February 2007, the Company invested in the common stock of Vastview. Vastview is a fabless semiconductor company that
develops and markets driver ICs and other ICs for the TFT-LCD industry. In September 2009, Vastview reduced 70% of its share capital and distributed NT$25,849 thousand (US$809 thousand) to the Company.

In November 2006, the Company invested in the common stock of Chipmast. Chipmast is a fabless semiconductor company that develops and
markets microcontrollers for LCDs. In August 2007, the Company sold all its investment in Chipmast and recognized a realized investment gain of NT$4,991 thousand.

The Company accounts for these investments using the cost method. These investments are evaluated for impairment on an annual basis or as
the circumstances warrant. For the years ended December 31, 2007, 2008 and 2009, we determined that our investments in Spright and Vastview were impaired because a combination of recurring losses and reduced forecasts at Spright and Vastview
indicated that the Companys investments were not recoverable within a reasonable period of time. Accordingly, the Company believed that the impairments were other than temporary and recorded an impairment charge of NT$14,447 thousand,
NT$69,253 thousand and NT$8,630 thousand (US$270 thousand) for the years ended December 31, 2007, 2008 and 2009, respectively. The impairment charges were determined based on the difference between the Companys carrying value and the
proportionate ownership of the investees net assets as of the respective year end.

Our fiscal 2009 impairment test included an evaluation
of long-lived assets used in our mobile communication reporting unit. These assets included customer relationships, core technology and property, plant and equipment. These assets were acquired during fiscal 2007 during the purchases of FCI. The
carrying value of the assets was compared to the fair value and impairment recorded where the carrying value exceeded fair value. The fair values of core technology and customer relationship were determined using the discounted cash flows method.
The fair value of property and equipment and other assets primarily represented replacement costs adjusted to reflect the impact of physical deterioration as well as applicable functional or economic obsolescence. The impairment charge related to
long-lived assets totaled NT$217,189 thousand (US$6,798 thousand) and is comprised of core technology NT$171,139 thousand (US$5,356 thousand), property and equipment NT$27,943 thousand (US$875 thousand) and other assets NT$18,107 thousand
(US$567 thousand). The impairment charge was mainly attributable to the weaker than expected financial performance due to the economic recession in Korea, technology transitions and the push out of growth opportunities.

Amortization expense of acquisition-related intangible assets was NT$163,704 thousand, NT$193,800 thousand and NT$192,391 thousand
(US$6,021 thousand) for the years ended December 31, 2007, 2008 and 2009, respectively. The estimated future amortization expense of acquisition-related intangible assets as of December 31, 2009 is as follows:

As a result of the goodwill impairment test conducted
as of November 30, 2009, the Company determined that the carrying amounts for mobile communication unit exceed its fair value and recorded a goodwill impairment charge in the fourth quarter of 2009. The impairment charge was mainly attributable
to the reporting units weaker than expected financial performance due to the economic recession in Korea, technology transitions and the push out of growth opportunities.

13. PENSION PLAN

The Labor Pension Act (the Act) of Taiwan 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 were allowed to 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 shall be maintained. The Act prescribes that the rate of contribution by an employer to employees pension accounts per month shall not be less than 6% of each employees monthly salary. The
Company made monthly contributions and recognized pension costs of NT$12,624 thousand, NT$13,941 thousand and NT$15,091 (US$472 thousand) for the years ended December 31, 2007, 2008 and 2009, respectively.

The Company has a defined benefit plan under the Labor Standards Law that provides 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 fund (the Fund), 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 (originally the Central Trust of China, which was merged into the Bank of Taiwan on July 1, 2007). The
government is responsible for the administration of all the defined benefit plans for the companies in Taiwan under the Labor Standards Law. The government also sets investment policies and strategies, determines investment allocation and selects

managers. As of December 31, 2008 and 2009, 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 companies 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, 2010 to be NT$1,702 thousand which was determined based on 2% of estimated salaries
in 2010. The annual measurement date of the plan is December 31.

The changes in benefits obligation and plan assets and
the reconciliation of funded status are as follows:

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. The valuation allowance increased by NT$43,993 thousand and NT$425,612 thousand (US$13,359 thousand) for the year ended December 31, 2008 and 2009,
respectively. The increase in valuation allowance is primarily due to the Company being unable to generate sufficient taxable income in the future to fully utilize operating loss carryforwards and research and development credits before they expire.
As of December 31, 2009, SMI Taiwan had unused research and development tax credits of NT$144,956 thousand (US$4,537 thousand) which will expire in 2011 to 2013. In addition, profits generated from certain products are exempted from income tax
for five years beginning January 1, 2006.

As of December 31, 2009, FCI had unused research and development tax
credits of approximately NT$19,588 thousand (US$ 613 thousand) which will expire in 2013.

As of December 31, 2009, the
Companys United States federal net operating loss carryforwards for federal income tax purposes were approximately NT$574,844 thousand (US$17,992 thousand). If not utilized, the federal net operating loss carryforwards will expire in 2020.

As of December 31, 2009, the Companys United States federal and state research and development tax credit
carryforwards for federal and state income tax purposes were approximately NT$51,024 thousand (US$1,597 thousand) and NT$39,394 thousand (US$1,233 thousand), respectively. If not utilized, the federal tax credit carryforwards will expire starting in
2021 while the state tax credit carryforward has no expiration date.

Current United States 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.

Unrecognized Tax Benefit

A reconciliation of the beginning and ending balances of the total amounts of unrecognized tax benefits is as follows:

Effective January 1, 2007, the Company adopted standards that clarified the accounting for uncertain
tax positions and in connection with this adoption recorded an adjustment to retained earnings of NT$12,000 thousand.

At
December 31, 2009, the Company had NT$ 93,892 thousand (US$ 2,939 thousand) of unrecognized tax benefits that if recognized would affect the effective tax rate. For the years ended December 31, 2007, 2008 and 2009, the total amount of
interest expense and penalties related to uncertain tax positions recorded in the provision for income expense was approximately NT$2,815 thousand, NT$1,963 thousand and NT$2,681 thousand (US$84 thousand), respectively. The total amount of accrued
interest and penalties recognized as of December 31, 2008 and 2009 was NT$4,037 thousand and NT$6,943 thousand (US$217 thousand), respectively. The Company does not anticipate any material change in the total amount of unrecognized tax benefits
to occur within the next twelve months.

The Company files income tax returns in US and foreign jurisdictions. The following
table summarizes the Companys major jurisdictions and tax year that remain subject to examination by such jurisdictions tax authorities as of December 31, 2009:

Share Repurchase Program

On March 12 and August 13, 2008, our Board of Directors approved share buyback plans to repurchase up to US$80 million of the
Companys ADSs during the period from March 12, 2008 to August 14, 2010. The program does 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. All the treasury stock under this share repurchase program was retired on August 2009.

In the year ended
December 31, 2008, the Company repurchased 6.2 million of ADSs for a total cost of US$54.3 million. The weighted average purchase price per ADS repurchased was US$8.76. The Company did not repurchase any ADs in the year ended
December 31, 2009.

16. EQUITY INCENTIVE PLAN

2004 Stock Option Plan and 2005 Equity Incentive Plan

In 2004, SMI Taiwan adopted a 2004 Employee Stock Option Plan (the 2004 Plan). The 2004 Plan reserved 8,000 options with
each option exercisable into for 1,000 shares of common stock. The options may be granted to qualified employees of the Company or any of its domestic or foreign subsidiaries and expire no later than six years from the date of grant. The options
were granted at an exercise price not lower than the market value of SMI Taiwans common stock at the date of the grant and vest over four years at certain percentages after two years from the date of grant. As part of the share exchange
between the Company and the shareholders of SMI Taiwan effective on April 25, 2005, the Company agreed to assume the share options previously issued by SMI Taiwan. Subsequently on June 3, 2005, the Company amended the 2004 Plan such that
options under the 2004 Plan are granted at an exercise price not lower than the market value of the Companys ordinary shares at the date of the grant and vest over four years at certain percentages after one year from the date of grant.

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 of 2 to 5 years. The Companys restricted stock units are considered nonvested share awards as defined under ASC 718.

At December 31, 2009, the Companys Compensation Committee approved the acceleration of 858 thousand restricted stock
units. There is no remaining requisite service periods on these restricted stock units and as a result of modifications, the expense that would have been recognized over the remaining vesting period was accelerated. The amount of the accelerated
restricted stock units expense was NT$ 23,132 thousand (US$ 724 thousand) which was recorded in the Companys fourth quarter 2009 financial results. No incremental compensation cost resulted from this option modification.

At December 31, 2009, 1,222 thousand restricted stock units were canceled by the Company. No compensation was received by the
restricted stock units holders for the cancelation. As a result of the modification, the expense that would have been recognized over the remaining vesting period was accelerated. The amount of the canceled restricted stock units expense was
NT$198,682 thousand (US$ 6,219 thousand) which was recorded in the Companys fourth quarter 2009 financial results. There were approximately 203 employees affected by these modifications.

In April 2010, the Companys Board of Directors and Compensation Committee approved an employee stock option exchange program that
require 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 $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 $1.47, which is 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, we 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.

As of December 31, 2009, total unrecognized compensation cost related to non-vested share-based compensation awards granted under the
Companys stock option plans, net of estimated forfeitures, was NT$4,181 thousand (US$131 thousand). This cost will be amortized over a weighted average period of approximately 0.79 years.

The aggregate intrinsic value represents the total intrinsic value (the difference between the Companys closing stock price on the
last trading day of fiscal year 2009 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2009. As the stock
price at the end of 2009 was below the option price for all shares, there is no intrinsic value for outstanding options at December 31, 2009 and options vested and expected to vest after December 31, 2009. Intrinsic value will change in
future periods based on the fair market value of the Companys stock and the number of shares outstanding.

The total
cash received from employees as a result of employee stock option exercises for the years ended December 31, 2007, 2008 and 2009 were NT$104,453 thousand, NT$33,751 thousand and nil, respectively.

The related tax effect for stock-based compensation benefit (expense) were NT$13,422 thousand, NT$8,724 thousand, and NT$(8,306) thousand
(US$260 thousand) for 2007, 2008 and 2009, respectively. The related tax effect for stock-based compensation expense for option and restricted stock units exercised during 2007, 2008 and 2009 was NT$5,464 thousand, NT$11,854 thousand and NT$51,956
thousand (US$1,626 thousand), respectively. The related tax effect was determined using the applicable tax rates in jurisdictions to which this expense relates.

Determining Fair Value

The Company estimated the fair value of each option grant on the date of grant using the Black-Scholes option pricing model. The
Black-Scholes option valuation model was developed for estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation model requires the input of highly subjective assumptions,
including the expected stock price volatility. The Company used the following weighted-average assumptions for each year in calculating the fair value of the options granted:



|                        |  |                        |   |  |            |

|Expected dividend yield |  |                       |   |  |           |  
|Expected volatility     |  | 45.85%-51.88           | % |  | 56.26      | %
|Risk free interest rate |  | 4.54%-4.59             | % |  | 3.25       | %
|Expected life           |  | 0.8-3.08 years         |   |  | 3.08 years |  

Risk-free
interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. Prior to 2008, expected volatilities were calculated based on historical volatilities of the stock prices of companies similar to the Company, when the Company
did not have sufficient historical data as a public company to determine reasonable estimates. Starting in 2008, expected volatilities are determined based on historical volatilities of the stock prices of the Company. Expected life represents the
periods that the Companys share- based awards are expected to be outstanding and was determined based on historical experience regarding similar awards, giving consideration to the contractual term of the share based awards. The dividend yield
is zero as the Company has never declared or paid dividends on the ordinary shares or other securities and does not anticipate paying dividends in the foreseeable future.

17. COMMITMENTS AND CONTINGENCIES

In 2000, FCI entered into a government grant agreement with Koreas Ministry of Knowledge Economy (MKE) to develop new
technologies. The agreement requires FCI, in accordance with the Industrial Technology Development Operation Guideline (Guideline) issued by MKE, to repay 20-30% of funds received and accordingly the Company has recorded the repayment
obligations as current and long-term payables. The remaining 70-80% of funds received in the amount of NT$127,404 thousand (US$3,889 thousand) were recognized in periods when costs funded by the grant are incurred. If the project is unsuccessful,
the agreement requires FCI to repay 100% of the funds received. As of December 31, 2009, FCI had thus far not been required to repay grant funds under the agreement with MKE and FCI has determined that no contingent liabilities were required as
of December 31, 2008 and 2009 based on historical experience and assessed probability of project success. In addition, if the project is not successful and FCI is deemed to have conducted the project with due care, we believe it is reasonable
that FCI will be released from its repayment obligations.

FCI provided their employees with collateral for personal loans by depositing at a designated bank NT$27,453 thousand (US$859 thousand) at
December 31, 2008 and 2009. 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 June 2014. The Company
recognized rent expense for the years ended December 31, 2007, 2008 and 2009 of NT$43,744 thousand, NT$40,810 thousand and NT$43,838 thousand (US$1,372 thousand), respectively. The minimum operating lease payments expected under these leases as
of December 31, 2009 were NT$33,703 thousand, NT$14,330 thousand, NT$7,599 thousand, NT$5,673 thousand, and NT$5,592 for the years ending December 31, 2010, 2011, 2012, 2013 and 2014, 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.

On May 1, 2005, SMI Taiwan incurred a loss on inventory in the possession of a subcontractor, Advanced Semiconductor Engineering
Inc., or ASE, due to a fire. On December 12, 2005, SMI Taiwan filed an action against ASE with the Taiwan Taoyuan District Court. SMI Taiwan alleged that ASE destroyed the wafers which SMI Taiwan had sub-contracted to ASE with the OEM Agreement
between SMI and ASE, and that ASE should pay SMI Taiwan a sum of NT$77,218 thousand for damages, for an amount exceeding the book value of lost inventory. After consultation with the Companys outside legal counsel, the Company believed it was
highly probable for the Company to receive reimbursement for the lost inventory at full book value, and the Company subsequently recorded NT$41,226 thousand of inventory loss, offset by NT$41,226 thousand of fire loss reimbursement, resulting in
zero impact to the earnings for the period. In connection with the inventory loss, the Company also recorded NT$8,122 thousand under non-operating expenses for amounts paid to certain customers for delays in shipments caused by the fire. In April
2010, ASE settled with SMI Taiwan by paying a settlement fee NT$35,000 thousand. On April 28, 2010, the Taiwan Taoyuan District Court granted a motion to dismiss the claim filed by SMI Taiwan against ASE.

On October 23, 2007, SanDisk Corp. (SanDisk) filed a complaint with the United States International Trade Commission
(ITC) against multiple respondents, including Silicon Motion Technology Corp., SMI Taiwan and SMI USA (in aggregate Silicon Motion). SanDisk claimed that certain Silicon Motion flash memory controllers and products containing
these Silicon Motion flash memory controllers infringed specific SanDisk patents. The complaint requested the ITC institute an investigation into the matter and sought a permanent exclusion order to exclude from entry into the United States all
flash memory controllers and products containing controllers that infringe any of the asserted patents. The complaint also sought a permanent cease and desist order, directing respondents to cease and desist from marketing, advertising,
demonstrating, sampling, warehousing inventory for distribution, offering for sale, selling, distributing, licensing, or using any flash memory controllers and products containing flash controllers that infringe any of the asserted patents. On
December 6, 2007, the ITC instituted an investigation, identifying forty-seven companies, including Silicon

Motion, as respondents. An ITC hearing was held as scheduled from October 27 through November 5, 2008. In post-hearing briefing, the Office of Unfair Import Investigation
(OUII) Staff Attorney agreed with our position that none of the Silicon Motion controllers infringed the SanDisk patents in suit. On April 10, 2009, the Administrative Judge of the ITC issued an initial determination that Silicon
Motion flash controllers and products containing these Silicon Motion flash controllers did not infringe the patents of SanDisk. On October 23, 2009, the ITC determined that Silicon Motion was not in violation of Section 337 of the Tariff
Act of 1930 and terminated its investigation.

On October 24, 2007, SanDisk filed two complaints, for alleged patent
infringement against multiple defendants, including Silicon Motion in the United States District Court for the Western District of Wisconsin. The complaints alleged that Silicon Motions flash memory controllers infringed certain SanDisk
patents and sought unspecified damages, injunctive relief, a trebling of damages for alleged willful conduct and attorneys fees. Both cases were stayed until SanDisks ITC proceeding became final. SanDisk entered into settlement with,
Silicon Motion and no settlement payments were required from Silicon Motion. On February 4, 2010, the Court ordered the dismissal of SanDisks claims against Silicon Motion without prejudice pursuant to SanDisks requests.

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 in the bankruptcy case pending in the U.S. Bankruptcy Court for the Southern District of Florida. The
AASI Creditor Liquidating Trust was seeking the return of allegedly avoidable transfers in the amount of NT$27,977 thousand (US$854 thousand). The Company filed an answer and affirmative defenses. In March 2010, SMI USA settled with the
AASI Creditor Liquidating Trust by paying the amount of US$220 thousand, of which US$65 thousand was accrued for as of December 31, 2009, and on April 1, 2010, the Bankruptcy Court granted the motion to approve stipulations to compromise
controversy.

On September 11, 2009, FCI filed a claim against Automobile & PCB Inc. (ANP) for
losses caused by the sale of products using substandard PCB substrates supplied by this vendor. At the time of FCIs procurement of the PCB substrates and prior to a change of name in February 2009, ANP was known as Quality &
Technology Korea Inc.(Q&Tec). FCI is claiming approximately US$500 thousand in losses from ANP for material, assembly, testing, and validation costs. The claim was filed at the Seongnam Municipal Court in Koreas
Gyeonggi Province and judgment is expected to be delivered by the court in mid-2010.

For investments other than forward and cross currency swap contracts, 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. For the year ended December 31, 2009, none of the Companys financial assets measured on a recurring basis was
determined by using observable inputs other than level 1.

The following table presents our assets measured at fair value on a
recurring basis as of December 31, 2008 and 2009:
