NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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 months ended September 30, 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 financial data 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, variable interest entities and useful lives for property and equipment and for intangible assets.

Recently Issued Accounting Guidance

In September 2011, the FASB issued an amendment to Topic 350, Intangibles-Goodwill and Other, which simplifies how entities test goodwill for impairment. Previous guidance under Topic 350 required an entity to test goodwill for impairment using a two-step process on at least an annual basis. First, the fair value of a reporting unit was calculated and compared to its carrying amount, including goodwill. Second, if the fair value of a reporting unit was less than its carrying amount, the amount of impairment loss, if any, was required to be measured. Under the amendments in this update, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads the entity to determine that it is more likely than not that its fair value is less than its carrying amount. If after assessing the totality of events or circumstances, an entity determines that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then the two-step impairment test is unnecessary. If the entity concludes otherwise, then it is required to test goodwill for impairment under the two-step process as described under Topic 350. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 and early adoption is permitted. The Company currently does not have goodwill and does not expect the adoption of the updated guidance have an impact 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

Table of Contents

credit standards, 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:



	Three Months Ended September 30,
Percentage of revenue	2011		2010
Customer A	17.3	%	30.7	%
Customer B	44.9	%	37.6	%
Customer C	14.4	%	11.1	%



	September 30,		June 30,
Percentage of trade receivables	2011		2011
Customer A	14.1	%	28.5	%
Customer B	7.6	%	32.7	%
Customer C	36.7	%	14.0	%

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 September 30, 2011, one of the Company's subsidiaries in China had a revolving line of credit that allows the Company to draw down, from time to time, up to 80% of the balance of the subsidiary's accounts receivable with a maximum amount of 40 million Chinese Renminbi (equivalent of $6,253,000 as of September 30, 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 September 30, 2011 , the outstanding loan balance was $4,000,000. The effective interest rate for the borrowing was 3.6% for the three months ended September 30, 2011 . There was no outstanding borrowing balance at June 30, 2011.

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 three months ended September 30, 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 September 30, 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 to shareholders' equity.

9. Income Taxes

The Company recognized income tax expense of approximately $773,000 and $756,000 for the three months ended September 30, 2011 and 2010, respectively. The estimated effective tax rate was 26.5% and $7.9% for the three months ended September 30, 2011 and 2010, respectively. The effective tax rate for the three months ended September 30, 2011 was substantively higher than the effective tax rate for the three months ended September 30, 2010 primarily due to a change in the

Table of Contents

mix of earnings in various geographic jurisdictions between the two periods. The effective tax rates for the three months ended September 30, 2011 and 2010 were lower than the U.S. statutory tax rate of 34% primarily as a result of the Company's net income in jurisdictions in which the tax rates are lower than the U.S. statutory tax rate.

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 September 30, 2011, the gross amount of unrecognized tax benefits was approximately $6,600,000. 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 September 30 and June 30, 2011 , the Company had approximately $22,455,000 and $22,014,000 outstanding purchase commitments for purchases of semiconductor raw materials, wafers and packaging and testing services, respectively.

As of September 30, and June 30, 2011 , the Company had approximately $2,733,000 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, becomes 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.

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 190 patents and 202 patents applications in the United States at the end of September 30, 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. While we currently utilize third-party foundries for our wafer fabrication, we are in the process of transition from a fabless to a “fab-lite” business model. Under this model, we intend to allocate our wafer manufacturing requirements to both in-house and outsourced capacities, which we believe 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 transition, we recently announced our intention to acquire certain assets associated with a 200mm wafer fabrication facility located in Hillsboro, Oregon from Integrated Device Technology, Inc, or IDT. 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 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 months ended September 30, 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 our products are used in consumer electronics products, our revenue is subject to seasonality. Our sales seasonality is affected

Table of Contents

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 period broad fluctuations in the semiconductor markets and the global economic conditions have had a more significant impact on our results 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.

As part of our transition to a "fab-lite" business model, on August 27, 2011, we announced our intention to acquire certain assets associated with a wafer fabrication facility from IDT. The transaction is expected to complete prior to January 31, 2012. 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 to three quarters following the proposed acquisition, and during this period, we expect our gross margin will be adversely affected by as much as 5% initially as a result of this acquisition but gradually improve as we ramp up the production at the facility during the 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 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 the date of acquisition. On December 3, 2010, 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 our 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 introductions 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 provide to our distributors. Stock rotation returns are governed by contract and are limited to a specified percentage of the

Table of Contents

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 absolute 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 absolute 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 absolute 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 $83.4 million for the three months ended September 30, 2011 , decreased by $6.0 million, or 6.7%, from $89.4 million for the three months ended September 30, 2010 . The decrease was primarily a result of a 17.3% 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 3.5% increase in unit shipments and a $6.4 million increase in packaging and testing services revenue. Revenue from our power IC products, which was also affected by the market softness, decreased by $3.9 million, or 22.9%, to $13.3 million for the three months ended September 30, 2011 from $17.3 million for the three months ended September 30, 2010 .

Cost of goods sold and gross profit

Gross profit	$	20,577		$	24,145		$	(3,568	)	(14.8	)%
Percentage of revenue	24.7		%	27.0		%

Cost of goods sold was $62.9 million for the three months ended September 30, 2011 , decreased by $2.4 million, or 3.7%, from $65.3 million for the three months ended September 30, 2010 , primarily as a result of decrease in average unit costs due to a shift in product mix. Our gross margin decreased by 2.3% to 24.7% for the three months ended September 30, 2011 from 27.0% for the three months ended September 30, 2010 . This decrease was primarily due to lower factory utilization and selling price erosion during the three months ended September 30, 2011 as a result of softened demand in a slowdown of economy. 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 as much as 5% during an initial ramp-up period of two to three quarters following the proposed acquisition of IDT's wafer fabrication facility. However, we expect our gross margin will gradually improve as we ramp up the production at the facility during the subsequent quarters.

Research and development expenses



	Three Months Ended September 30,
	2011		2010		Change
	(in thousands)				(in thousands)		(in percentage)
Research and development	$	8,394	$	6,259	$	2,135	34.1	%

Research and development expenses were $8.4 million for the three months ended September 30, 2011 , increased by $2.1 million, or 34.1%, from $6.3 million for the three months ended September 30, 2010 . This increase was primarily attributable to a $2.1 million increase in products prototyping and engineering expenses primarily associated with qualifying IDT's fabrication facility and a $0.3 million increase in depreciation and amortization expenses, partially offset by a $0.3 million decrease in salaries and bonuses expenses and a $0.1 million decrease in share-based compensation expense.

Selling, general and administrative expenses



	Three Months Ended September 30,
	2011		2010		Change
	(in thousands)				(in thousands)		(in percentage)
Selling, general and administrative expenses	$	9,283	$	9,198	$	85	0.9	%

Selling, general and administrative expenses were $9.3 million for the three months ended September 30, 2011 , increased by $0.1 million, or 0.9%, from $9.2 million for the three months ended September 30, 2010 . This slight increase was primarily due to a $0.4 million increase in audit fees related to our financial statement conversion from International Financial Reporting Standards, or IFRS, to U.S. GAAP and a $0.2 million increase in general and administrative expenses incurred by APM as we acquired APM in December 2010, offset by a $0.5 million decrease in legal expenses and a $0.1 million decrease in share-based compensation expense.

Our income on equity investment in APM was $0.9 million for the three months ended September 30, 2010. This amount represented our share of APM's net income for the three months ended September 30, 2010. APM's operating results were consolidated in our consolidated financial statements after we acquired APM in December 2010.

Income tax expense

	2011		2010		Change
	(in thousands)				(in thousands)	(in percentage)
Income tax expense	$	773	$	756	17	2.2	%

We recognized income tax expense of approximately $0.8 million for both the three months ended September 30, 2011 and 2010. The quarterly effective tax rate was 26.5% and $7.9% for the three months ended September 30, 2011 and 2010, respectively. Our effective tax rate for the three months ended September 30, 2011 was substantively higher than the effective tax rate for the three months ended September 30, 2010 primarily due to a change in the mix of earnings in various geographic jurisdictions between the two periods. Our effective tax rates for the three months ended September 30, 2011 and 2010 were lower than the U.S. statutory tax rate of 34% primarily as a result of our net income in jurisdictions in which the tax rates are lower than the U.S. statutory tax rate.

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, proceeds from our IPO, and the issuance of preferred shares.

As of September 30, 2011, one of our subsidiaries in China had a revolving line of credit that allows us to draw down, from time to time, up to 80% of the balance of the subsidiary's accounts receivable with a maximum amount of 40 million Chinese Renminbi (equivalent of $6.3 million as of September 30, 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 September 30, 2011 , the outstanding loan balance was $4.0 million. The effective interest rate for the borrowing was 3.6% for the the three months ended September 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 September 30, 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 to shareholders' equity.

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 financing covenants that would restrict our operations. We cannot assure you that financing will be available in the amounts we need or on terms acceptable to us, if at all.

Cash and cash equivalents

As of September 30, 2011 and June 30, 2011, we had $88.4 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.

The following table shows our net cash generated from operating activities, net cash used in investing activities and net cash generated from financing activities for the periods indicated:



	Three Months Ended September 30,

Net cash provided by financing activities		2,409				31

Net increase in cash and cash equivalents		$	1,698			$	7,268

Cash flows from operating activities

Our net cash generated from operating activities for the three months ended September 30, 2011 was $11.9 million, which primarily consisted of $7.1 million non-cash items of depreciation and amortization and share-based compensation expense, net income of $2.1 million and $2.7 million increase in working capital accounts. Our accounts receivable decreased by $17.0 million due to fewer shipments for the three months ended September 30, 2011. Our inventories reduced by $11.9 million as we reduced our production level and inventory purchases in response to fewer orders placed by our customers. Accordingly, our accounts payable also decreased by $22.2 million.

Our net cash generated from operating activities for the three months ended September 30, 2010 was $18.3 million, primarily due to our strong operating results and an increase in accounts payable for inventory purchases.

Cash flows from investing activities

Our net cash used in investing activities was $12.7 million for the three months ended September 30, 2011 , which was primarily attributable to $12.6 million in purchases of property and equipment mainly to expand our in-house production capacity.

Our net cash used in investing activities was $11.0 million for the three months ended September 30, 2010 which was primarily attributable to $11.6 million in purchases of property and equipment to expand our in-house packaging and testing capacity, offset by $0.6 million in release of restricted cash.

Cash flows from financing activities

Our net cash generated from financing activities for the three months ended September 30, 2011 was $2.4 million, which was principally attributable to $4.0 million proceeds from our revolving line of credit, offset by $1.6 million used to repurchase our common shares under our share repurchase program.

Our net cash generated from financing activities for the three months ended September 30, 2010 was $31,000, which was primarily attributable to $4.4 million proceeds from our revolving lines of credit, partially offset by $3.7 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 $12.6 million and $11.6 million for the three months ended September 30, 2011 and 2010, respectively. Our capital expenditures principally consisted of the purchases of property and equipment. Capital expenditures for the three months ended September 30, 2011 primarily consisted of purchases of packaging and testing equipment for our two in-house manufacturing facilities and purchases of equipment consigned to IDT. Following the acquisition of APM in December 2010, we rely primarily on our in-house capacities for packaging and testing our products and expect to do so in the future. We utilize third-party foundries for wafer fabrication, and our capital expenditures related to the wafer fabrication

process are primarily for the purchases of certain specialized equipment that are consigned to our third-party foundries to support our production requirement.

In August 2011, we announced our intention to exercise an option to acquire certain assets associated with the IDT wafer manufacturing facility, which is located in Hillsboro, Oregon for a total purchase price of $26 million. We have obtained this option as part of the consideration for us entering into a foundry service agreement with IDT and a cash prepayment of $5.0 million which will be applied to the purchase price. We expect to execute a definitive asset purchase agreement for the acquisition by the end of calendar year 2011and close the transaction by the end of January 2012. During the initial ramp-up period of the IDT facility, which is expected to last for approximately two to three quarters, 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 September 30 , 2011 and June 30, 2011 , the Company had approximately $22.5 million and $22.0 million of outstanding purchase commitments for purchases of semiconductor raw materials, wafers and packaging and testing services, respectively.

As of September 30, 2011 and June 30, 2011 , the Company had approximately $2.7 million and $5.2 million of capital commitments for the purchase of property and equipment, respectively.

Off-Balance Sheet Arrangements

As of September 30, 2011 , we had no material off-balance sheet arrangements as defined in Regulation S-K 303(a)(4)(ii).

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 September 30, 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 three months ended September 30, 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.
