ALPHA AND OMEGA SEMICONDUCTOR LIMITED
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1. The Company and Significant Accounting Policies
The Company
Alpha and Omega Semiconductor Limited and its subsidiaries (the “Company”, "AOS", "we" or "us") design, develop and supply a broad range of power semiconductors. The Company's portfolio of products targets high-volume applications, including portable computers, flat panel TVs, smart phones, battery packs, portable media players, motor control and power supplies. The Company conducts its operations primarily in the United States of America (“USA”), Hong Kong, Macau, China, Taiwan, Korea and Japan.
Basis of Preparation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Article 10 of Securities and Exchange Commission Regulation S-X. They do not include all information and footnotes necessary for a fair presentation of financial position, results of operations and cash flows in conformity with U.S. GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company’s Annual Report on Form 10-K for the year ended June 30, 2011. All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the results of operations for the period presented have been included in the interim period. Operating results for the three and six months ended December 31, 2011 are not necessarily indicative of the results that may be expected for other interim periods or the year ending June 30, 2012. The condensed consolidated balance sheet at June 30, 2011 is derived from the audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2011.
Use of Estimates
The preparation of our consolidated financial statements in conformity with U.S. GAAP requires the Company to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. To the extent there are material differences between these estimates and actual results, the Company's consolidated financial statements will be affected. On an ongoing basis, the Company evaluates the estimates, judgments and assumptions including those related to revenue recognition, inventory reserves, warranty reserve, income taxes, share-based compensation and useful lives for property and equipment and for intangible assets.
Recent Accounting Pronouncements
In September 2011, the Financial Accounting Standards Board ("FASB") issued authoritative guidance that allows entities to first assess qualitatively whether it is necessary to perform the two-step goodwill impairment test. If any entity believes, as a result of its qualitative assessment, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative two-step goodwill impairment test is required. An entity has the unconditional option to bypass the qualitative assessment and proceed directly to performing the first step of the goodwill impairment test. The guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company does not expect the adoption of these provisions to have a significant effect on its consolidated financial statements.
In June 2011, the FASB issued authoritative guidance that amends the presentation requirements for comprehensive income in financial statements. The guidance requires entities to report components of comprehensive income either as part of a single continuous statement of comprehensive income that would combine the components of net income and other comprehensive income, or in a separate, but consecutive, statement following the statement of income. The guidance is effective for interim and annual periods beginning after December 15, 2011 and is to be applied retrospectively. The Company does not expect the adoption of these provisions to have a significant effect on its consolidated financial statements.

2. Concentration of Credit Risk and Significant Customers
The Company manages its credit risk associated with exposure to distributors and direct customers on outstanding trade receivables through the application of credit approvals, credit ratings and other monitoring procedures. In some instances, the Company also obtains letters of credit from certain customers.
Credit sales, which are mainly on credit terms of 30 to 60 days, are only made to customers who meet the Company's credit policy, while sales to new customers or customers with low credit ratings are usually made on an advance payment basis. The Company's management considers the Company's financial assets to be of good credit quality because its key distributors and direct customers have long-standing business relationships with the Company and the Company has not experienced any significant bad debt write-offs of trade receivables in the past. The Company's management closely monitors the aging of receivables from its distributors and direct customers, and regularly reviews their financial positions, when available.
Summarized below are individual customers whose revenue or trade receivable balances were 10% or higher than the respective total consolidated amounts:

3. Segment and Geographic Information
The Company is organized as, and operates in, one operating segment: design, development and marketing of power semiconductor products for computing, consumer electronics, communication and industrial applications. The chief operating decision-maker is the Chief Executive Officer. The financial information presented to the Company's Chief Executive Officer is on a consolidated basis, accompanied by information about revenue by customer and geographic region, for purposes of evaluating financial performance and allocating resources. The Company has one business segment, and there are no segment managers who are held accountable for operations, operating results and plans for products or components below the consolidated unit level. Accordingly, the Company reports as a single operating segment.
The Company sells its products primarily to distributors in the Asia Pacific region, who in turn sell these products to end customers. Because the Company's distributors sell their products to end customers which may have global presence, revenue by geographical location is not necessarily representative of the geographical distribution of sales to end user markets. The revenue by geographical location in the following tables is based on the country or region to which the products were shipped:

5. Bank Borrowings
As of December 31, 2011, two of the Company's subsidiaries in China had revolving lines of credit that allow each of the subsidiaries to draw down, from time to time, up to 80% of the balance of such subsidiary's accounts receivable with a maximum amount of 40 million Chinese Renminbi (RMB) (equivalent of $6,313,000 based on the currency exchange rate as of December 31, 2011) to finance the subsidiary's accounts receivable on a maximum of 120-day repayment term. The interest rate on each drawdown varies and indexes to the published London Interbank Offered Rate per annum. As of December 31, 2011, the total outstanding balance for the lines of credit aggregated $10,700,000. The effective interest rate for the borrowings was in the range of 3.8% to 4.3% for the six months ended December 31, 2011. There was no outstanding borrowing balance at June 30, 2011.

6. Shareholders' Equity and Share-based Compensation
Shares Repurchase
On October 22, 2010, the Company's board of directors authorized a $25.0 million share repurchase program. Under this repurchase program the Company may, from time to time, repurchase shares from the open market or in privately negotiated transactions, subject to supervision and oversight by the board. During the six months ended December 31, 2011, the Company repurchased 191,170 shares from the open market for a total cost of $1,574,000, at an average price of $8.23 per share. As of December 31, 2011, the Company repurchased an aggregate of 241,170 shares for a total cost of $2,267,000, at an average price of $9.40 per share. Shares repurchased are accounted for as treasury shares and the total cost of shares repurchased is recorded as a reduction of shareholders' equity.

9. Income Taxes

The Company recognized income tax expense of approximately $839,000 and $564,000 for the three months ended December 31, 2011 and 2010, respectively. The Company recognized income tax expense of approximately $1,612,000 and $1,320,000 for the six months ended December 31, 2011 and 2010, respectively. The estimated effective tax rate was 36.3%

11

Table of Contents

and 6.1% for the three months ended December 31, 2011 and 2010, respectively. The estimated effective tax rate was 30.9% and 7.0% for the six months ended December 31, 2011 and 2010, respectively. The effective tax rate for the three and six months ended December 31, 2011 was higher than the effective tax rate for the three and six months ended December 31, 2010 primarily due to a change in the mix of earnings in various geographic jurisdictions between the two periods.
    
The Company files federal and state income tax returns in the United States and in various foreign jurisdictions. The tax years 2001 to 2011 remain open to examination by U.S. federal and state tax authorities. The tax years 2005 to 2011 remain open to examination by material foreign tax authorities.
The Company is subject to ongoing tax examinations of our tax returns by the Internal Revenue Service and other tax authorities in various jurisdictions. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. These assessments can require considerable estimates and judgments. As of December 31, 2011, the gross amount of unrecognized tax benefits was approximately $6,646,000. If the estimates of income tax liabilities proves to be less than the ultimate assessment, then a further charge to expense would be required. If events occur and the payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period in which the Company determines the liabilities are no longer necessary. The Company does not anticipate any material changes to its uncertain tax positions during the next twelve months.

10. Commitments and Contingencies
As of December 31 and June 30, 2011, the Company had approximately $23,037,000 and $22,014,000 of outstanding purchase commitments for purchases of semiconductor raw materials, wafers and packaging and testing services, respectively, and approximately $1,784,000 and $5,170,000 capital commitments for the purchase of property and equipment, respectively.

The Company is currently not a party to any material legal proceedings. The Company had in the past, and may from time to time in the future, become involved in legal proceedings arising from the normal course of business activities. The semiconductor industry is characterized by frequent claims and litigation, including claims regarding patent and other intellectual property rights as well as improper hiring practices. Irrespective of the validity of such claims, the Company could incur significant costs in the defense thereof or could suffer adverse effects on its operations.
Guarantees
We indemnify our directors and certain employees as permitted by law, and have entered into indemnification agreements with our directors and executive officers. We have not recorded a liability associated with these indemnification arrangements, as we historically have not incurred any material costs associated with such indemnification obligations. Costs associated with such indemnification obligations may be mitigated by insurance coverage that we maintain, however, such insurance may not cover any, or may cover only a portion of, the amounts we may be required to pay. In addition, we may not be able to maintain such insurance coverage in the future.
We also have indemnification clauses in various contracts that we enter into in the normal course of business, such as indemnifications in favor of customers in respect of liabilities they may incur as a result of purchasing our products should such products infringe the intellectual property rights of a third party. We have not historically paid out any material amounts related to these indemnifications, therefore, no accrual has been made for these indemnifications.

11. Acquisitions of Wafer Fabrication Facility

On December 14, 2011 the Company entered into an agreement to acquire certain assets, including land, building, and equipment, associated with a wafer fabrication facility located in Hillsboro, Oregon from Integrated Device Technology, Inc, or IDT, for a purchase price of $26.0 million plus certain assumed liability. The Company previously paid a cash deposit of $5 million, which was applied to the purchase price. The purchase price is subject to adjustment based on changes in the value of certain inventory utilized in the maintenance and repair of the equipment located at the facility. The acquisition was completed on January 31, 2012.

Unless the context otherwise requires, the words “AOS,” the “Company,” “we,” “us” and “our” refer to Alpha and Omega Semiconductor Limited and its subsidiaries.

This management’s discussion should be read in conjunction with the management’s discussion included in the Company’s
Annual Report on Form 10-K for the fiscal year ended June 30, 2011, previously filed with Securities and Exchange
Commission.
Overview
We are a designer, developer and global supplier of a broad range of power semiconductors. We have a broad portfolio of power semiconductors that we actively market and we seek to continuously add to our product portfolio each year. Our portfolio of power semiconductors is extensive, with over 900 products, and has grown rapidly with the introduction of over 120 new products each year during the past three fiscal years. In addition, our patent portfolio has grown to include 211 patents and 198 patents applications in the United States as of December 31, 2011. We seek to differentiate ourselves by integrating our expertise in device physics, process technology, design and advanced packaging to optimize product performance and cost. Our portfolio of products targets high-volume applications, including portable computers, flat panel TVs, smart phones, battery packs, portable media players, motor control and power supplies.
Our transnational business model leverages global resources, including leading research and development expertise in the United States, cost-effective semiconductor manufacturing in Asia and localized sales and technical support in several fast-growing electronics hubs globally. Our core research and development team, based in Silicon Valley, is complemented by our design center in Taiwan and process, packaging and testing engineers in China. We have recently transitioned from a fabless to a “fab-lite” business model. Under this model, we allocate our wafer manufacturing requirements to both in-house capacity and selected third-party foundries. We believe that this model would allow us to accelerate technology development, bring products to market faster, reduce manufacturing costs and improve our long-term financial performance. As part of this business model, we entered into an agreement on December 14, 2011 to acquire certain assets associated with a 200mm wafer fabrication facility located in Hillsboro, Oregon from Integrated Device Technology, Inc, or IDT, and the acquisition was completed on January 31, 2012. We also deploy and implement our proprietary power discrete processes and equipment at third-party foundries to maximize the performance and quality of our products. We primarily rely upon our two in-house facilities in China for packaging and testing our products. We believe our in-house packaging and testing capability provides us with a competitive advantage in proprietary packaging technology, product quality, cost, flexibility and cycle time.
Factors affecting our performance
Our performance is affected by several key factors, including the following:
Global and regional economic conditions: Because our products primarily serve consumer applications, a deterioration of the global and regional economic conditions could materially affect our revenue and results of operations. In June 2011, we began to experience a general slow down of global economic conditions, particularly in our core computing and consumer markets, that have adversely affected our results of operations for the three and six months ended December 31, 2011. We cannot be certain as to how long this trend will continue and how much negative impact it will have on our results of operations.
Distributor ordering patterns and seasonality: Our distributors place purchase orders with us based on their forecasts of end customer demand, and this demand may vary significantly depending on the sales outlooks and market and economic conditions of end customers. Because these forecasts may not be accurate, channel inventory held at our distributors may fluctuate significantly, which in turn may prompt distributors to make significant adjustments to their purchase orders placed with us. As a result, our revenue and operating results may fluctuate significantly from quarter to quarter. In addition, because

13

Table of Contents

our products are used in consumer electronics products, our revenue is subject to seasonality. Our sales seasonality is affected by a number of factors, including global and regional economic conditions, revenue generated from new products, changes in distributor ordering patterns in response to channel inventory adjustments and end customer demand for our products and fluctuations in consumer purchase patterns prior to major holiday seasons. However, in recent periods broad fluctuations in the semiconductor markets and the global and regional economic conditions have had a more significant impact on our results of operations than seasonality.
Product introductions and customers' specification: Our success depends on our ability to introduce products on a timely basis that meet our customers' specifications. Both factors, timeliness of product introductions and conformance to customers' requirements, are equally important in securing design wins with our customers. Our failure to introduce products on a timely basis that meet customers' specifications could adversely affect our financial performance.
Erosion of average selling price: Erosion of average selling prices of established products is typical in our industry. Consistent with this historical trend, we expect that average selling prices of our established products will continue to decline in the future. However, as a normal course of business, we seek to offset the effect of declining average selling prices by reducing manufacturing cost of existing products and introducing new and higher value products.
Manufacturing costs: Our gross margin may be affected by our manufacturing costs, including pricing of wafers and semiconductor raw materials, which may fluctuate from time to time largely due to the market demand and supply. Capacity utilization may also affect our gross margin because we have certain fixed costs associated with our in-house packaging and testing facilities. If we are unable to utilize the capacity of our in-house manufacturing facilities at a desirable level, our gross margin may be adversely affected.

On January 31, 2012, we completed the acquisition of the IDT fabrication facility as part of our strategy to transition from a fabless to a "fab-lite" business model. We expect the IDT wafer fabrication facility acquisition to accelerate our technology and product development and reduce our manufacturing costs, thereby improving our long-term financial performance. However, we currently anticipate an initial ramp-up period of two quarters following the acquisition, during which, we expect our gross margin will be adversely affected by approximately 3% initially as a result of this acquisition but gradually improve as we ramp up the production at the facility during subsequent quarters. On a long term basis, we expect the “fab-lite” model will have a positive impact on our gross margin by allowing us to develop high-value products more quickly and in a more cost-effective manner.
Other factors that may affect comparability
APM acquisition: We held a 40.3% equity interest in Agape Package Manufacturing Ltd. (APM) at September 30, 2010. We made an additional equity investment of $1.8 million in APM in October 2010 resulting in a 43% equity interest in APM. The investment was accounted for under the equity method of accounting through December 3, 2010, the date we acquired APM, and APM's operating results were reflected in our consolidated financial statements subsequent to that date.
Change in accounting estimate: During the second quarter of our fiscal year 2011, upon the completion of the APM acquisition, we performed a review and assessment of the useful lives of certain of our property and equipment. Based on the results of our review, we revised the estimated useful life of our manufacturing and facility equipment for depreciation purposes from 5 years to 8 years beginning December 1, 2010 on a prospective basis.
Principal line items of statements of income
The following describes the principal line items set forth in our condensed consolidated statements of income:
Revenue
We generate revenue primarily from the sale of power semiconductors, consisting of power discretes and power ICs. Historically, a majority of our revenue was derived from power discrete products and a small but growing amount was derived from power IC products. Because our products typically have three to five years life cycles, the rate of new product introduction is an important driver of revenue growth over time. We believe that expanding the breadth of our product portfolio is important to our business prospects, because it provides us with an opportunity to increase our total bill-of-materials within an electronic system and to address the power requirements of additional electronic systems. In addition, a small percentage of our total revenue is generated by providing packaging and testing services to third-parties through APM, our subsidiary and in-house packaging facility.
Our product revenue includes the effect of the estimated stock rotation returns and price adjustments that we expect to

14

Table of Contents

provide to our distributors. Stock rotation returns are governed by contract and are limited to a specified percentage of the monetary value of products purchased by the distributor during a specified period. At our discretion or upon our direct negotiations with ODMs or OEMs, we may elect to grant special pricing that is below the prices at which we sold our products to the distributors; in these situations, we will grant price adjustments to the distributors reflecting such special pricing. We estimate the price adjustments for inventory at the distributors based on factors such as distributor inventory levels, pre-approved future distributor selling prices, distributor margins and demand for our products.
Cost of goods sold
Our cost of goods sold primarily consists of costs associated with semiconductor wafers, packaging and testing, manufacturing personnel, including share-based compensation expense, overhead attributable to manufacturing, operations and procurement, and costs associated with yield improvements, capacity utilization, warranty and inventory reserves. As the volume of sales increases, we expect cost of goods sold to increase in absolute dollar amount.
Operating expenses
Our operating expenses consist of research and development and selling, general and administrative expenses. We expect that our total operating expenses will generally increase in dollar amount over time due to our belief that our business will continue to grow. However, our operating expenses as a percentage of revenue may fluctuate from period to period.
Research and development expenses.  Our research and development expenses consist primarily of salaries, bonuses, benefits, share-based compensation expense, expenses associated with new product prototypes, travel expenses, fees for engineering services provided by outside contractors and consultants, amortization of software and design tools, depreciation of equipment and overhead costs for research and development personnel. As we continue to invest significant resources in developing new technologies and products, we expect our research and development expenses to increase in dollar amount.
Selling, general and administrative expenses.  Our selling, general and administrative expenses consist primarily of salaries, bonuses, benefits, share-based compensation expense, product promotion costs, occupancy costs, travel expenses, expenses related to sales and marketing activities, amortization of software, depreciation of equipment, maintenance costs and other expenses for general and administrative functions as well as costs for outside professional services, including legal, audit and accounting services. We expect our selling, general and administrative expenses to increase in dollar amount as we expand our business.
Income on equity investment in APM
We had a 40.3% equity interest in APM at September 30, 2010. We made an additional equity investment of $1.8 million in APM in October 2010 and held a 43% equity interest in APM prior to the APM acquisition on December 3, 2010. Our investment in APM was accounted for under the equity method of accounting for the period prior to December 3, 2010. Accordingly, we recorded income on equity investment in APM in our statements of income prior to the APM acquisition. Since the acquisition, the results of APM's operations are consolidated.
Income tax expense
We are subject to income taxes in various jurisdictions. Significant judgment and estimates are required in determining our worldwide income tax expense. The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations of different jurisdictions globally. We establish accruals for potential liabilities and contingencies based on a more likely than not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits us to recognize a tax benefit measured at the largest amount of tax benefit that is more than likely to be realized upon settlement. If the actual tax outcome of such exposures is different from the amounts that were initially recorded, the differences will impact the income tax and deferred tax provisions in the period in which such determination is made. Changes in the location of taxable income (loss) could result in significant changes in our income tax expense.
We record deferred tax assets to the extent that it is more likely than not that we will be able to utilize them, based on historical profitability and our estimate of future taxable income in a particular jurisdiction. Our judgments regarding future taxable income may change due to changes in market conditions, changes in tax laws, tax planning strategies or other factors. If our assumptions and consequently our estimates change in the future, the deferred tax assets may increase or decrease, resulting in corresponding changes in income tax expense. Our effective tax rate is highly dependent upon the geographic distribution of our worldwide profits or losses, the tax laws and regulations in each geographical region where we have operations, the availability of tax credits and carry-forwards and the effectiveness of our tax planning strategies.

Our revenue was $80.7 million for the three months ended December 31, 2011, a decrease of $3.3 million, or 3.9%, from $84.0 million for the three months ended December 31, 2010. The decrease was primarily a result of an 8.8% decline in average selling prices mainly due to a shift in product mix and selling price erosion caused by softened demand in the computing and consumer markets, offset by a 0.7% increase in unit shipments and a $3.4 million increase in packaging and testing services revenue. Revenue from our power IC products, which was also affected by the market softness, decreased by $2.7 million, or 17.1%, to $13.0 million for the three months ended December 31, 2011 from $15.6 million for the three months ended December 31, 2010.
Our revenue was $164.2 million for the six months ended December 31, 2011, a decrease of $9.2 million, or 5.3%, from $173.4 million for the six months ended December 31, 2010. The decrease was primarily a result of a 13.0% decline in average selling prices mainly due to a shift in product mix and selling price erosion caused by softened demand in the computing and consumer markets, offset by a 2.1% increase in unit shipments and a $9.8 million increase in packaging and testing services revenue. Revenue from our power IC products, which was also affected by the market softness, decreased by $6.6 million, or 20.1%, to $26.3 million for the six months ended December 31, 2011 from $32.9 million for the six months ended December 31, 2010.

Cost of goods sold was $62.4 million for the three months ended December 31, 2011, increased by $1.7 million, or 2.7%, from $60.8 million for the three months ended December 31, 2010, primarily as a result of low factory utilization and increase in raw material prices. Our gross margin decreased by 5.0% to 22.6% for the three months ended December 31, 2011 from 27.6% for the three months ended December 31, 2010. This decrease was primarily due to selling price erosion, lower factory utilization during the three months ended December 31, 2011 as a result of softened demand in the computing and consumer markets. We expect that our gross margin will continue to fluctuate in the future as a result of variations in our product mix, factory utilization, semiconductor wafer and raw material pricing, manufacturing labor cost and general economic conditions. In addition, we expect our gross margin will be adversely affected by approximately 3% during the initial ramp-up period of two quarters following the acquisition of IDT's wafer fabrication facility. However, we expect our gross margin to gradually improve as we ramp up the production at the facility during subsequent quarters.

Cost of goods sold was $125.3 million for the six months ended December 31, 2011, a decrease of $0.7 million, or 0.6%, from $126.1 million for the six months ended December 31, 2010, primarily as a result of low factory utilization and increase in raw material prices. Our gross margin decreased by 3.6% to 23.7% for the six months ended December 31, 2011 from 27.3% for the six months ended December 31, 2010. This decrease was primarily due to the selling price erosion and lower factory

Research and development expenses were $8.1 million for the three months ended December 31, 2011, increased by $1.5 million, or 22.7%, from $6.6 million for the three months ended December 31, 2010. This increase was primarily attributable to a $1.8 million increase in product prototyping and engineering expenses associated with qualifying IDT's fabrication facility and a $0.2 million increase in depreciation and amortization expenses, partially offset by a $0.5 million decrease in salaries and bonuses expenses.

We recognized income tax expense of approximately $0.8 million and $0.6 million for the three months ended December 31, 2011 and 2010, respectively. The quarterly effective tax rate was 36.3% and 6.1% for the three months ended December 31, 2011 and 2010, respectively. Our effective tax rate for the three months ended December 31, 2011 was higher than the effective tax rate for the three months ended December 31, 2010 primarily due to a change in the mix of earnings in various geographic jurisdictions between the two periods.

We recognized income tax expense of approximately $1.6 million and $1.3 million for the six months ended December 31, 2011 and 2010, respectively. The quarterly effective tax rate was 30.9% and 7.0% for the six months ended December 31, 2011 and 2010, respectively. Our effective tax rate for the six months ended December 31, 2011 was higher than the effective tax rate for the six months ended December 31, 2010 primarily due to a change in the mix of earnings in various geographic jurisdictions between the two periods.

Liquidity and Capital Resources

    Our principal need for liquidity and capital resources is to maintain working capital sufficient to support our operations and to make capital expenditures to finance the growth of our business. To date, we have primarily financed our operations through funds generated from operations, borrowings under our former term loan and current revolving lines of credit, and proceeds from our initial public offering.
    As of December 31, 2011, two of the Company's subsidiaries in China had revolving lines of credit that allow each of the subsidiaries to draw down, from time to time, up to 80% of the balance of such subsidiary's accounts receivable with a maximum amount of 40 million RMB (equivalent of $6.3 million as of December 31, 2011) to finance the subsidiary's accounts receivable on a maximum of 120-day repayment term. The interest rate on each drawdown varies and indexes to the published London Interbank Offered Rate per annum. As of December 31, 2011, the total outstanding balance for the lines of credit aggregated $10.7 million. The effective interest rate for the borrowings was in the range of 3.8% to 4.3% for the six months ended December 31, 2011. There was no outstanding borrowing balance at June 30, 2011.

On October 22, 2010, our board of directors authorized a $25.0 million share repurchase program. Under this repurchase program our management may, from time to time, repurchase shares from the open market or in privately negotiated transactions, subject to supervision and oversight by the board. As of December 31, 2011, we repurchased an aggregate of 241,170 shares from the open market for a total cost of $2.3 million, at an average price of $9.40 per share. Shares repurchased are accounted for as treasury shares and the total cost of shares repurchased is recorded as a reduction of shareholders' equity.

We completed the acquisition of certain assets associated with a wafer fabrication facility of IDT on January 31, 2012 and paid the remaining $21.0 million toward to the $26.0 million purchase price.
We believe that our current cash and cash equivalents and cash flows from operations will be sufficient to meet our anticipated cash needs, including working capital and capital expenditures, for at least the next twelve months. In the long-term, we may require additional capital due to changing business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If our cash is insufficient to meet our needs, we may seek to raise capital through equity or debt financing. The sale of additional equity securities could result in dilution to our shareholders. The incurrence of indebtedness would result in increased debt service obligations and may include operating and financial covenants that would restrict our operations. We cannot assure you that any financing will be available in the amounts we need or on terms acceptable to us, if at all.

Cash and cash equivalents
As of December 31, 2011 and June 30, 2011, we had $97.3 million and $86.7 million of cash and cash equivalents, respectively. Our cash and cash equivalents primarily consist of cash on hand and short-term bank deposits with original maturities of three months or less.

Cash flows from operating activities

Our net cash generated from operating activities for the six months ended December 31, 2011 was $22.8 million, which primarily consisted of $3.6 million net income, $14.5 million of non-cash items including depreciation and amortization and share-based compensation expense, and a $4.5 million net increase in working capital accounts. Our accounts receivable decreased by $7.5 million due to fewer shipments for the six months ended December 31, 2011. Our inventories decreased by $19.1 million as part of our response to the softened demand in the computing and consumer markets. Related to the reduction of the inventories, our accounts payable also decreased by $21.8 million.

Our net cash generated from operating activities for the six months ended December 31, 2010 was $23.2 million, primarily due to our strong operating results.
Cash flows from investing activities
    
Our net cash used in investing activities was $22.0 million for the six months ended December 31, 2011, which was primarily attributable to $21.9 million in purchase of property and equipment mainly to expand our in-house production capacity.

Our net cash used in investing activities was $28.1 million for the six months ended December 31, 2010, which was primarily attributable to $20.6 million in purchases of property and equipment to expand our in-house packaging and testing capacity, a $5.0 million deposit for manufacturing capacity, a $1.8 million investment in APM prior to the APM acquisition and $1.3 million used, net of cash acquired, in the APM acquisition.
Cash flows from financing activities
Our net cash generated from financing activities for the six months ended December 31, 2011 was $9.8 million, which was primarily attributable to $14.7 million of proceeds from our revolving lines of credit, partially offset by $4.0 million of repayments under the same revolving lines of credit, and $1.6 million used to repurchase our common shares under the share repurchase program.

Our net cash generated from financing activities for the six months ended December 31, 2010 was $240,000, which was primarily attributable to $10.6 million of proceeds from our revolving lines of credit and $2.2 million of proceeds from ESPP and share options exercise, partially offset by $11.7 million repayments under the same revolving lines of credit and $0.6 million in payments for our IPO costs.
Capital expenditures
Our capital expenditures were $21.9 million and $20.7 million for the six months ended December 31, 2011 and 2010, respectively. Our capital expenditures principally consisted of purchases of property and equipment. Capital expenditures for the six months ended December 31, 2011 primarily consisted of purchases of packaging and testing equipment for our two in-

house manufacturing facilities and purchases of equipment consigned to IDT. Prior to the acquisition of the IDT fabrication facility, we utilized third-party foundries for wafer fabrication, and our capital expenditures related to the wafer fabrication process was primarily for the purchase of certain specialized equipment that are consigned to our third-party foundries to support our production requirement. On January 31, 2012, we closed the IDT acquisition and paid the remaining $21.0 million toward to the purchase price of $26.0 million as we had previously paid IDT a deposit of $5.0 million. Following the IDT acquisition, we expect to use a combination of in-house capacity and third party foundries for our wafer manufacturing requirements. During the ramp-up period of the IDT facility, we may incur additional costs and expenses relating to integration of the wafer fabrication facility, including costs for additional personnel, raw materials, equipment and other overhead expenses.
Commitments

As of December 31, 2011 and June 30, 2011, we had approximately $23.0 million and $22.0 million of outstanding purchase commitments for purchases of semiconductor raw materials, wafers and packaging and testing services, respectively.
As of December 31, 2011 and June 30, 2011, we had approximately $1.8 million and $5.2 million of capital commitments for the purchase of property and equipment, respectively.
Off-Balance Sheet Arrangements
We indemnify our directors and certain employees as permitted by law, and have entered into indemnification agreements with our directors and executive officers. We have not recorded a liability associated with these indemnification arrangements, as we historically have not incurred any material costs associated with such indemnification obligations. Costs associated with such indemnification obligations may be mitigated by insurance coverage that we maintain, however, such insurance may not cover any, or may cover only a portion of, the amounts we may be required to pay. In addition, we may not be able to maintain such insurance coverage in the future.
    
We also have indemnification clauses in various contracts that we enter into in the normal course of business, such as indemnifications in favor of customers in respect of liabilities they may incur as a result of purchasing our products should such products infringe the intellectual property rights of a third party. We have not historically paid out any material amounts related to these indemnifications, therefore, no accrual has been made for these indemnifications.

Other than as set forth above, we are not currently party to any material off-balance sheet arrangements.

Recent Accounting Pronouncements
In September 2011, the Financial Accounting Standards Board ("FASB") issued authoritative guidance that allows entities to first assess qualitatively whether it is necessary to perform the two-step goodwill impairment test. If any entity believes, as a result of its qualitative assessment, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative two-step goodwill impairment test is required. An entity has the unconditional option to bypass the qualitative assessment and proceed directly to performing the first step of the goodwill impairment test. The guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. We do not expect the adoption of these provisions to have a significant effect on our consolidated financial statements.
In June 2011, the FASB issued authoritative guidance that amends the presentation requirements for comprehensive income in financial statements. The guidance requires entities to report components of comprehensive income either as part of a single continuous statement of comprehensive income that would combine the components of net income and other comprehensive income, or in a separate, but consecutive, statement following the statement of income. The guidance is effective for interim and annual periods beginning after December 15, 2011 and is to be applied retrospectively. We do not expect the adoption of these provisions to have a significant effect on our consolidated financial statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes in the market risks previously disclosed in Part II, Item 7A, "Quantitative and Qualitative Disclosures About Market Risk," of our Annual Report on Form 10-K for the year ended June 30, 2011, filed with the SEC on September 9, 2011.

ITEM 4. CONTROLS AND PROCEDURES
Management's Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) as of the end of the period covered by this report. Our disclosure controls and procedures are designed to ensure that information required to be disclosed is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission ("SEC") and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2011, our disclosure controls and procedures were effective.
Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting during the six months ended December 31, 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Limitation on Effectiveness of Controls
It should be noted that any system of controls, no matter how well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the system are met. The design of any control system is based, in part, upon the benefits of the control system relative to its costs. Control systems can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. In addition, over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies and procedures may deteriorate. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events.


PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS
We are currently not a party to any material legal proceedings. We have in the past, and may from time to time in the future, become involved in legal proceedings arising from the normal course of business activities. 

ITEM 1A. RISK FACTORS

We expect to incur significant capital expenditures and fixed manufacturing costs in connection with the acquisition of our new fabrication facility, which may negatively impact our results of operations, and the operation of our own fabrication facility may subject us to additional risks.

On January 31, 2012, we completed the acquisition of certain assets associated with IDT's 200mm wafer fabrication facility located in Hillsboro, Oregon. Following the acquisition of the IDT fabrication facility, we expect to incur significant costs and expenses relating to the integration and operation of our own wafer fabrication facility, including costs for additional personnel, raw materials, equipment and other overhead expenses. In addition, semiconductor manufacturing has historically required an upgrading of process technology from time to time to remain competitive, as new and enhanced semiconductor processes are developed which permit smaller, more efficient and more powerful semiconductor devices. Accordingly, we may have to make substantial capital expenditures and install significant production capacity at our in-house fabrication facility to support new technologies and increased production volume.

We expect our gross margin will be adversely affected by approximately 3% during the initial ramp-up period of two quarters following the closing of the acquisition. We may not be able to realize a sufficient return for our investment on the IDT assets, and failure to do so may have an adverse effect on our financial condition and results of operations.

The operation of our own fabrication facility may subject us to additional risks. In order to manage the capacity of the wafer fabrication facility efficiently, we must perform a forecast of long-term market demand and general economic conditions for our products. Because market conditions may vary significantly and unexpectedly, our forecast may change significantly at any time, and we may not be able to make timely adjustments to our fabrication capacity in response to these changes. During periods of continued decline in market demand, we may not be able to absorb the excess inventory and additional costs associated with operating the facility at higher capacity. Similarly, during periods of unexpected increase in customer demand, we may not be able to ramp up production quickly to meet these demands, which may lead to the loss of significant revenue opportunities.

Furthermore, the manufacturing processes of a fabrication facility are complex and subject to interruptions, and our experience in operating a wafer facility has been limited to active collaboration with third-party foundries. We may experience production difficulties, including lower manufacturing yields or products that do not meet our or our customers' specifications, and problems in ramping production and installing new equipment. These difficulties could result in delivery delays, quality problems and lost revenue opportunities. Any significant quality problems could also damage our reputation with our customers and could take focus away from the development of new and enhanced products. These could have a significant negative impact on our financial results.

We depend on other outside semiconductor foundries to manufacture our products and implement our fabrication processes, and any failure to maintain sufficient foundry capacity and control the cost of production could significantly delay our ability to ship our products, damage our relationships with customers, reduce our sales and increase expenses.

We currently primarily use third-party foundries for the fabrication of our wafers. We expect to continue to rely on third party foundries following the initial ramp-up period of the new fabrication facility. However, the allocation of our wafer production between in-house facility and third-party foundries may fluctuate from time to time.

We place our purchase orders with foundries based on sales forecasts for our products. If any third-party foundry does not provide competitive pricing or is not able to meet our required capacity for any reason, we may not be able to obtain the required capacity to manufacture our products timely or efficiently. If we cannot maintain sufficient capacity or control pricing with our existing third-party foundries, we may need to increase our own manufacturing capacity, and there is no assurance that we can ramp up the production of our in-house fabrication facility timely to meet the increased demand. If not, we may need to seek alternative foundries, which may not be available on commercially reasonable terms, or at all. In addition, the process for qualifying a new foundry is time consuming, difficult and may not be successful, particularly if we cannot integrate our proprietary process technology with the process used by the new foundry. Using a foundry with which we have no established relationship could expose us to potentially unfavorable pricing, unsatisfactory quality or insufficient capacity allocation.

In addition, we rely on third-party foundries to effectively implement our proprietary technology and processes and also require their cooperation in developing new fabrication processes. Any failure to do so may impair our ability to introduce new products. In order to maintain our profit margins and to meet our customer demand, we need to achieve acceptable production yields and timely delivery of silicon wafers. As is common in the semiconductor industry, we have experienced, and may experience from time to time, difficulties achieving acceptable production yields and timely delivery from third-party foundry vendors. Minute impurities in a silicon wafer can cause a substantial number of wafers to be rejected or cause numerous dice on a wafer to be defective. Low yields often occur during the production of new products, the migration of processes to smaller geometries or the installation and start up of new process technologies.
 
We face a number of other significant risks associated with outsourcing fabrication, including:

limited control over delivery schedules, quality assurance and control and production costs;

discretion of foundries to reduce deliveries to us on short notice, allocate capacity to other customers that may be larger or have long-term customer or preferential arrangements with foundries that we use;

unavailability of, or potential delays in obtaining access to, key process technologies;

limited warranties on wafers or products supplied to us;

damage to equipment and facilities, power outages, equipment or materials shortages that could limit manufacturing yields and capacity at the foundries;

potential unauthorized disclosure or misappropriation of intellectual property, including use of our technology by the

23

foundries to make products for our competitors;

financial difficulties and insolvency of foundries; and

acquisition of foundries by third parties.

 Any of the foregoing risks could delay shipment of our products, result in higher expenses and reduced revenue, damage our relationships with customers and otherwise adversely affect our business and operating results.

We have made and may continue to make strategic acquisitions of other companies, assets or businesses and these acquisitions introduce significant risks and uncertainties, including risks related to integrating the acquired assets or businesses, incurring additional debt, assuming contingent liabilities or diluting our existing shareholders.

In order to position ourselves to take advantage of growth opportunities, we have made, and may continue to make, strategic acquisitions, mergers and alliances that involve significant risks and uncertainties. Successful acquisitions and alliances in the semiconductor industry are difficult to accomplish because they require, among other things, efficient integration and aligning of product offerings and manufacturing operations and coordination of sales and marketing and research and development efforts. The difficulties of integration and alignment may be increased by the necessity of coordinating geographically separated organizations, the complexity of the technologies being integrated and aligned and the necessity of integrating personnel with disparate business backgrounds and combining different corporate cultures.

The integration of newly acquired assets or businesses will also require a significant amount of time and attention from management. On January 31, 2012, we completed the acquisition of certain assets associated with the IDT wafer fabrication facility located in Hillsboro, Oregon. The integration of the new fabrication facility will require significant internal and external coordination. The diversion of management attention away from ongoing operations and key research and development, marketing or sales efforts could adversely affect ongoing operations and business relationships. Moreover, even if we were able to fully integrate the new wafer fabrication facility successfully, there can be no assurance that this integration will result in the realization of the full benefits of synergies, cost savings, innovation and operational efficiencies that may be possible from this integration or that these benefits will be achieved within a reasonable period of time. Delays in integrating the new fabrication facility, which could be caused by factors outside of our control, could adversely affect the intended benefits of our business, operating results, financial condition and stock price.

In addition, we may also issue equity securities to pay for future acquisitions or alliances, which could be dilutive to existing shareholders. We may also incur debt or assume contingent liabilities in connection with acquisitions and alliances, which could impose restrictions on our business operations and harm our operating results.

If we are unable to introduce or develop new and enhanced products that meet our customers' specifications in a timely manner, our operating results and competitive position would be harmed.

Our future success will depend on our ability to continue to introduce, develop and distribute new products and product enhancements that meet the specifications of our customers in a timely and cost-effective manner. Our customers are mainly ODMs and OEMs who are focused on reducing their number of vendors that they use. As a result, our ability to introduce new products rapidly and to maintain an extensive product portfolio is critical to developing and maintaining successful customer relationships. The development of our products is highly complex and our products must conform to the specifications or standards of our customers. We have, at times, experienced delays in completing the development and introduction of new products and product enhancements. Successful product development and customer acceptance of our products depend on a number of factors, including:
    
timely introduction and completion of new designs and timely qualification and certification of our products for use in our end customers' products;

commercial acceptance and volume production of the products into which our products will be incorporated;

market trends towards integration of discrete components into one device;

our ability to adequate availability of foundry, packaging and testing capacity;

achievement of high manufacturing yields;


24

availability, quality, price, performance, power use and size of our products relative to those of our competitors;

our customer service, application support capabilities and responsiveness;

successful development and expansion of our relationships with existing and potential customers; and

changes in technology, industry standards, end customer requirements or end user preferences and our ability to anticipate those changes.

We cannot guarantee that products which we recently developed or may develop in the future will meet customers' specifications on a timely basis or at all, or that we will be able to develop products that will allow us to enter into new markets. We expect to face new and significant challenges in our effort to enter into these highly competitive markets in which we did not have a presence historically. Even if we are able to develop new products that allow us to enter into these new markets initially, we may not be able to sustain the effort on a long term-basis or establish sufficient market share to achieve meaningful returns from our investment. Our failure to do so will adversely affect our business, results of operations, financial condition and prospects.

Except as set forth above there have been no material changes to the risk factors we previously disclosed under Item 1A of Part I of our Annual Report on Form 10-K for the year ended June 30, 2011, filed with the SEC on September 9, 2011. The risk factors set forth in our Form 10-K and Form 10-Q are not the only risks we face. Our operations could also be affected by additional factors that are not presently known to us or by factors that we currently consider immaterial to our business.
