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 personal computers, flat panel TVs, LED lighting, smart phones, battery packs, quick chargers, home appliances, consumer and industrial motor controls and power supplies for TVs, computers, servers and telecommunications equipment. The Company conducts its operations primarily in the United States of America (“USA”), Hong Kong, China, and South Korea.

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, as amended. 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 fiscal year ended June 30, 2019. 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 periods presented have been included in the interim periods. Operating results for the three months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending June 30, 2020 or any other interim period. The condensed consolidated balance sheet at June 30, 2019 is derived from the audited financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2019.

During the quarter ended September 30, 2019, the Company corrected the prior year amount of property and equipment purchased but not yet paid in the supplemental disclosures of non-cash investing and financing information by decreasing it by $34.7 million, from $57.2 million to $22.5 million. This disclosure change had no effect on the consolidated statements of operations and cash flows for the quarter ended September 30, 2018.

Leases

On July 1, 2019, the Company adopted Topic 842, Leases, using the modified retrospective method. Results for reporting periods beginning after July 1, 2019 were presented under Topic 842, while prior period amounts were not adjusted and continue to be reported in accordance with its historic accounting under Topic 840.

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, current operating lease liabilities and long-term operating lease liabilities on the Company's condensed consolidated balance sheets. Finance leases are included in property, plant and equipment, finance lease liabilities and long-term finance leases liabilities on the condensed consolidated balance sheets.

The Company elected the practical expedient permitted under the transition guidance, which allowed the Company to carryforward its historical lease classification, the Company's assessment on whether a contract was or contains a lease, and its initial direct costs for any leases that existed prior to July 1, 2019. The Company elected to combine its lease and non-lease components as a single lease component for all asset classes.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company uses an estimate of its incremental borrowing rate based on the information available at the lease commencement date. The operating lease ROU assets also include any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. Operating lease expense is generally recognized on a straight-line basis over the lease term. Variable lease payments are expensed as incurred and are not included

within the operating lease ROU asset and lease liability calculation. The Company does not record leases on the condensed consolidated balance sheet with a term of one year or less.

See Note 6 for further details.

Joint Venture

In March 2016, the Company executed an agreement with two strategic investment funds owned by the Municipality of Chongqing, China (the "Chongqing Funds") to form a joint venture, (the "JV Company"), for a new state-of-the-art power semiconductor packaging, testing and wafer fabrication facility in Liangjiang New Area of Chongqing (the "Joint Venture"). As of September 30, 2019, the Company owns 51%, and the Chongqing Funds own 49% of the equity interest in the JV Company. The Joint Venture is accounted for under the provisions of the consolidation guidance since the Company has a controlling financial interest. The JV Company has continued ramping up its production of assembly and testing during the September 2019 quarter. In July 2019, the JV Company commenced limited mass production at the 12-inch wafer fabrication facility.

Use of Estimates

The preparation of the condensed 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 condensed consolidated financial statements will be affected. On an ongoing basis, the Company evaluates the estimates, judgments and assumptions including those related to stock rotation returns, price adjustments, allowance for doubtful accounts, inventory reserves, warranty accrual, income taxes, leases, share-based compensation, and useful lives for property, plant and equipment and intangible assets.

Share-based Compensation Expense

The Company recognizes expense related to share-based compensation awards that are ultimately expected to vest based on estimated fair values on the date of grant. The fair value of restricted share units is based on the market value of the Company's common share on the date of grant. For restricted stock awards subject to market conditions, the fair value of each restricted stock award is estimated at the date of grant using the Monte-Carlo pricing model. The fair value of stock options is estimated on the date of grant using the Black-Scholes option valuation model. Share-based compensation expense is recognized on the accelerated attribution basis, net of estimated forfeitures, over the requisite service period of the award, which generally equals the vesting period.

Fair Value of Financial Instruments

The fair value of cash equivalents is based on observable market prices and have been categorized in Level 1 in the fair value hierarchy. Cash equivalents consist primarily of short term bank deposits. The carrying values of financial instruments such as cash and cash equivalents, accounts receivable and accounts payable approximate their carrying values due to their short-term maturities. The carrying value of the company's debt is considered a reasonable estimate of fair value which is estimated by considering the current rates available to the Company for debt of the same remaining maturities, structure and terms of the debts.

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The Company's accumulated other comprehensive income (loss) consists of cumulative foreign currency translation adjustments. Total comprehensive income (loss) is presented in the condensed consolidated statements of comprehensive income (loss).

Recent Accounting Pronouncements

Recently Issued Accounting Standards not yet adopted

ALPHA AND OMEGA SEMICONDUCTOR LIMITED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-15 “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract ("ASU 2018-15”). These amendments align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contact with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by these amendments. ASU 2018-15 is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted. The Company is currently assessing the impact that adoption of this guidance will have on its consolidated financial statements.

In August 2018, the FASB issued Accounting Standard Updates ("ASU") ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13”). ASU 2018-13 amends existing fair value measurement disclosure requirements by adding, changing, or removing certain disclosures. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. ASU No. 2018-13 is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2019. The Company does not expect the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses ("ASU 2016-13"). This accounting standard update changes the accounting for recognizing impairments of financial assets. Under the update, credit losses for certain types of financial instruments will be estimated based on expected losses. The update also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the impact of this accounting standard update on its Consolidated Financial Statements.

Recently Adopted Accounting Standards

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This guidance requires a dual approach for lessee accounting under which a lessee accounts for leases as finance leases or operating leases. Both finance and operating leases result in the lessee recognizing a right-of-use asset and a corresponding liability on its balance sheet, with differing methodology for income statement recognition. The Company adopted this standard as of July 1, 2019, using the modified retrospective transition method and recorded a cumulative-effect balance sheet adjustment. As a result of adopting ASU 2016-02 on July 1, 2019, the Company recognized operating lease right-of-use assets and corresponding operating lease liabilities of approximately $21 million each from existing leases on the Company's condensed consolidated balance sheet. See Note 6 for further details.

In June 2018, the FASB issued ASU 2018-07, "Compensation -Stock Compensation: Improvement to Nonemployees Share-Based Payment Accounting ("ASU 2018-07"), which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606. ASU 2018-07 had no material impact on the Company's consolidated financial statements.

3. Concentration of Credit Risk and Significant Customers

The Company manages its credit risk associated with exposure to distributors and direct customers on outstanding accounts receivable through the application and review 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 requirements, while sales to new customers or customers with low credit ratings are usually made on an advance payment basis. The Company considers its trade accounts receivable 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 write-offs of accounts receivable in the past. The Company closely monitors the aging of accounts receivable from its distributors and direct customers, and regularly reviews their financial positions, when available.

Summarized below are individual customers whose revenue or accounts receivable balances were more than 10% of the respective total consolidated amounts:

6. Leases

Under Topic 842, the Company evaluates contracts for lease accounting at contract inception and assesses lease classification at the lease commencement date. Operating leases are included in operating lease right-of-use ("ROU") assets, operating lease liabilities and operating lease liabilities - long-term on the Company's consolidated balance sheets. Finance leases are included in property, plant and equipment, finance lease liabilities and finance lease liabilities-long-term on the consolidated balance sheets. The Company recognizes an ROU asset and corresponding lease obligation liability at the lease commencement date where the lease obligation liability is measured at the present value of the minimum lease payments. As most of the leases do not provide an implicit rate, the Company uses its incremental borrowing rate at lease commencement. The Company uses an interest rate commensurate with the interest rate to borrow on a collateralized basis over a similar term with an amount equal to the lease payments. Operating leases are primarily related to offices, research and development facilities, sales and marketing facilities, and manufacturing facilities. In addition, long-term supply agreements to lease gas tank equipment and purchase industrial gases are accounted for as operating leases. Lease agreements frequently include renewal provisions and require the Company to pay real estate taxes, insurance and maintenance costs. For operating leases, the amortization of the ROU asset and the accretion of its lease obligation liability result in a single straight-line expense recognized over the lease term. The finance lease is related to the RMB 400.0 million of lease financing with YinHai Leasing Company and China Import/Export Bank in the JV Company. See Note 5 - Bank Borrowings for details. The Company does not record leases on the condensed consolidated balance sheet with a term of one year or less.

7. Shareholders' Equity and Share-based Compensation

Share Repurchase

In September 2017, the Board of Directors approved a new repurchase program (the “Repurchase Program”) that allowed the Company to repurchase its common shares from the open market pursuant to a pre-established Rule 10b5-1 trading plan or through privately negotiated transactions up to an aggregate of $30.0 million. The amount and timing of any repurchases under the Repurchase Program depend on a number of factors, including but not limited to, the trading price, volume, and availability of the Company's common shares. Shares repurchased under this program are accounted for as treasury shares and the total cost of shares repurchased is recorded as a reduction of shareholders' equity. From time to time, treasury shares may be reissued as part of the Company's stock-based compensation programs. Gains on re-issuance of treasury stock are credited to additional paid-in capital; losses are charged to additional paid-in capital to offset the net gains, if any, from previous sales or re-issuance of treasury stock. Any remaining balance of the losses is charged to retained earnings.

During the three months ended September 30, 2019, the Company did not repurchase any shares from the open market. Since the inception of the program, the Company repurchased an aggregate of 6,784,648 shares from the open market for a total cost of $67.3 million, at an average price of $9.92 per share, excluding fees and related expenses. No repurchased shares have been retired. Of the 6,784,648 repurchased shares, 140,328 shares with a weighted average repurchase price of $10.39 per share, were reissued at an average price of $5.50 per share pursuant to option exercises and vested restricted share units. As of September 30, 2019, approximately $13.4 million remained available under the Repurchase Program.

Time-based Restricted Stock Units ("TRSU")

Market-based Restricted Stock Units ("MSUs")

During the quarter ended September 30, 2018, the Company granted 1.3 million market-based restricted stock units ("MSUs") to certain personnel. The number of shares to be earned at the end of performance period is determined based on the Company’s achievement of specified stock prices and revenue thresholds during the performance period from January 1, 2019 to December 31, 2021 as well as the recipients remaining in continuous service with the Company through such period. The MSUs vest in four equal annual installments after the end of each performance period. The Company estimated the grant date fair values of its MSUs with derived service periods of 4.5 to 7.5 years using a Monte-Carlo simulation model with the following assumptions: Risk-free interest rate of 2.7%, expected term of 3.5 years, expected volatility of 38.8% and dividend yield of 0%. The Company recorded approximately $0.2 million each of expense for these MSUs during the three months ended September 30, 2019 and 2018.

Performance-based Restricted Stock Units ("PRSUs")

In March 2017, 2018 and 2019, the Company granted 170,000, 298,050 and 291,750 performance-based RSUs (“PRSUs”), respectively to certain personnel. The number of shares to be earned under the PRSUs is determined based on the level of attainment of predetermined financial goals. The PRSUs vest in four equal annual installments from the first anniversary date after the grant date if certain predetermined financial goals were met. The Company recorded approximately $0.2 million and $0.6 million of expenses for these PRSUs during the three months ended September 30, 2019 and 2018, respectively.

As of September 30, 2019, total unrecognized compensation cost under the Company's equity plans was $10.7 million, which is expected to be recognized over a weighted-average period of 2.0 years.

8. Income Taxes

The Company recognized income tax expense of approximately $0.4 million and $0.6 million, for the three months ended September 30, 2019 and 2018, respectively. Excluding the discrete income tax items, the effective tax rate for the three months ended September 30, 2019 was (27.3)% compared to (159.8)% for the three months ended September 30, 2018. The changes in the effective tax rate and tax expense between the periods resulted primarily from changes in the mix of earnings in various geographic jurisdictions between the current year and the same period of last year.

The Company files its income tax returns in the United States and in various foreign jurisdictions. The tax years 2001 to 2019 remain open to examination by U.S. federal and state tax authorities. The tax years 2012 to 2019 remain open to examination by foreign tax authorities.

The Company's income tax returns are subject to examinations by the Internal Revenue Service and other tax authorities in various jurisdictions. In accordance with the guidance on the accounting for uncertainty in income taxes, 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, 2019, the gross amount of unrecognized tax benefits was approximately $7.2 million, of which $4.3 million, if recognized, would reduce the effective income tax rate in future periods. If the Company's estimate 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 when 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.

On July 27, 2015, in Altera Corp. v. Commissioner, the U.S. Tax Court issued an opinion related to the treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. In the July 2015 ruling, the Tax Court concluded that the sharing of the cost of employee stock compensation in a company’s cost-sharing arrangement was invalid under the U.S. Administrative Procedures Act. In June 2019, a panel of the Ninth Circuit of the U.S. Court of Appeals reversed this decision. In July 2019, Altera petitioned U.S. Court of Appeals for the Ninth Circuit to hold an en banc rehearing of the case. Due to the uncertainty surrounding the status of the current regulations and questions related to the scope of potential benefits, the Company has not recorded any benefit as of September 30, 2019. The Company will continue to monitor ongoing developments and potential impacts to its financial statements.

9. Segment and Geographic Information

The Company is organized as, and operates in, one operating segment: the design, development and supply 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.

10. Commitments and Contingencies

Purchase Commitments

As of September 30, 2019 and June 30, 2019, the Company had approximately $52.9 million and $59.5 million, respectively, of outstanding purchase commitments primarily for purchases of semiconductor raw materials, wafers, spare parts and packaging and testing services, and approximately $28.6 million and $33.8 million, respectively, of capital commitments for the purchase of property and equipment and EPC construction.

Other Commitments

See Note 5 and Note 6 of the Notes to the Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q for descriptions of commitments including bank borrowings and leases.

Contingencies and Indemnities

The Company is currently not a party to any pending material legal proceedings. The Company has 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 of such claims and suffer adverse effects on its operations.

The Company is a party to a variety of agreements that it has contracted with various third parties. Pursuant to these agreements, the Company may be obligated to indemnify another party to such an agreement with respect to certain matters. Typically, these obligations arise in the context of contracts entered into by the Company, under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations and covenants related to such matters as title to assets sold, certain intellectual property rights, specified environmental matters and certain income taxes. In these circumstances, payment by the Company is customarily conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party's claim. Further, the Company's obligations under these agreements may be limited in time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments made by it under these agreements. The Company has not historically paid or recorded any material indemnifications, and no accrual has been made at September 30, 2019 and June 30, 2019.

The Company has agreed to indemnify its directors and certain employees as permitted by law and pursuant to its Bye-laws, and has entered into indemnification agreements with its directors and executive officers. The Company has not recorded a liability associated with these indemnification arrangements, as it historically has not incurred any material costs associated with such indemnification obligations. Costs associated with such indemnification obligations may be mitigated by insurance coverage that the Company maintains. However, such insurance may not cover any, or may cover only a portion of, the amounts the Company may be required to pay. In addition, the Company may not be able to maintain such insurance coverage in the future.

11. Subsequent Events

In October 2019, the Company's subsidiary in China entered into a line of credit facility with Bank of Communications Limited in China. This line of credit matures on February 14, 2021 and is based on the China Base Rate multiplied by 1.05, or 4.99% on October 31, 2019. The purpose the credit facility was to provide short-term borrowings. The Company could borrow up to approximately RMB 60.0 million or $8.5 million based on the currency exchange rate between the RMB and the U.S. Dollar on October 31, 2019.

In October 2019, the Company’s expired line of credit with Industrial and Commercial Bank of China was renewed with a maturity date of September 30, 2020.

In October 2019, the JV Company borrowed additional $1.6 million under the 50.0 million RMB agreement that was with China Everbright bank in China. Interest payments with this entire principal is due no later than January 13, 2020.

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, 2019, filed with the Securities and Exchange Commission on August 23, 2019.

Overview

We are a designer, developer and global supplier of a broad portfolio of power semiconductors. Our portfolio of power semiconductors includes approximately 2,100 products, and has grown significantly with the introduction of 200 new products in each of the fiscal years ended June 30, 2019 and 2018, respectively, and over 80 new products in fiscal year 2017. During the three months ended September 30, 2019, we introduced an additional 55 new products. Our teams of scientists and engineers have developed extensive intellectual properties and technical knowledge that encompass major aspects of power semiconductors, which we believe enables us to introduce and develop innovative products to address the increasingly complex power requirements of advanced electronics. We have an extensive patent portfolio that consists of 791 patents and 91 patent applications in the United States as of September 30, 2019. We also have a total of 824 foreign patents, which primarily were based on our research and development efforts through September 30, 2019. We differentiate ourselves by integrating our expertise in technology, design and advanced manufacturing and packaging to optimize product performance and cost. Our portfolio of products targets high-volume applications, including personal computers, flat panel TVs, LED lighting, smart phones, battery packs, quick chargers, home appliances, consumer and industrial motor controls and power supplies for TVs, computers, servers and telecommunications equipment.

Our business model leverages global resources, including research and development and manufacturing in the United States and Asia. Our sales and technical support teams are localized in several growing markets. We operate an 8-inch wafer fabrication facility located in Hillsboro, Oregon, or the Oregon fab, which is critical for us to accelerate proprietary technology development, new product introduction and improve our financial performance in the long run. To meet the market demand for the more mature high volume products, we also utilize the wafer manufacturing capacity of selected third party foundries. For assembly and test, we primarily rely upon our in-house facilities in China. In addition, we utilize subcontracting partners for industry standard packages. We believe our in-house packaging and testing capability provides us with a competitive advantage in proprietary packaging technology, product quality, cost and sales cycle time.

On March 29, 2016, we entered into a joint venture contract (the “JV Agreement”) with two investment funds owned by the Municipality of Chongqing (the “Chongqing Funds”), pursuant to which we and the Chongqing Funds formed a joint venture, (the “JV Company”), for the purpose of constructing a power semiconductor packaging, testing and wafer fabrication facility in the Liangjiang New Area of Chongqing, China (the “JV Transaction”). We currently own 51%, and the Chongqing Funds own 49%, of the equity interest in the JV Company. The JV Company has continued ramping up its production of assembly and testing during the September 2019 quarter. In July 2019, we commenced limited mass production at the 12-inch wafer fabrication facility. We expect to ramp up activities gradually. During the three months ended September 30, 2019, we recorded $2.9 million in net loss attributable to noncontrolling interest in the JV Company. In the long-term, we expect the joint venture to deliver significant cost savings, enhance our market positions in China, and drive improvements in working capital and capital expenditures.

On September 5, 2017, we entered into a license agreement with STMicroelectronics International N.V. (“STMicro”), pursuant to which STMicro granted us a world-wide, royalty-free and fully-paid license to use its technologies to develop, market and distribute certain digital multi-phase controller products, which have been previously offered by STMicro. As of

September 30, 2019, we recorded $16.2 million of intangible assets on our condensed consolidated balance sheets. We will begin to amortize this intangible asset when the technology has met our qualification and is ready for its intended use in production.

During the first quarter of fiscal year of 2020, we introduced the “Source Down” in a DFN 5x6 package in combination with a 40V Shield-Gate Technology (AlphaSGT™). Our innovative flip-chip know-how achieves the Source Down capability and this packaging technology offers a very low package resistance and inductance. The AOE66410 is ideally suited in telecommunications applications for secondary rectification, in half bridge configuration for BLDC motor applications, and battery management where paralleling is important. In addition, we introduced the TO-Leadless (TOLL) package in combination with a 60V and 100V Shield-Gate Technology providing the highest current capability in its voltage class. The TOLL package has the highest current capacity due to our innovative technology, which utilizes a clip to achieve the in-rush current. The TOLL packaging technology offers a very low package resistance and inductance due to the clip technology when compared to other TO-Leadless packages. This packaging technology uses a standard wire-bonding technology which enables improved EMI performance.

Factors affecting our performance

Our performance is affected by several key factors, including the following:

Costs of JV Company and digital power business: We are incurring an increase in operating expenses due to the additional costs associated with ramping up pre-production and production ramp-up activities of the JV Company, as well as the initial startup work to develop and establish our new digital power business, both of which have had a significant impact on our financial performance. The JV Company has continued ramping up its production of assembly and testing during the September 2019 quarter. In July 2019, we commenced limited mass production at the 12-inch wafer fabrication facility. We expect to continue gradually ramping it up. The pre-production costs include costs relating to the installation of equipment; performance of the qualification process; increased demand for electrical power and other utilities; increased headcount as a result of hiring of additional personnel, staff and operators; and establishment of administrative and management functions and systems. Certain of such pre-production costs could be capitalized under U.S. GAAP accounting. However, the majority of such pre-production costs and all of the production ramp-up costs cannot be capitalized, therefore such costs have and may continue to have a negative impact on our profitability, although we do not expect to incur pre-production costs after July 2019 as the JV Company has commenced limited mass production.

In addition, we are developing our digital power business based on the STMicro license agreement, which will allow us to design and distribute a full suite of advanced low-voltage power IC products. We have incurred and expect to continue to incur additional costs, including costs relating to compensation of qualified engineers and technical staff and other research and development and management activities, as we continue to build this new business. In the short term, we will not be able to generate sufficient amount of revenue from either of these two business initiatives to offset the increased costs, which will likely negatively impact our results of operations.

Manufacturing costs: Our gross margin is affected by a number of factors including our manufacturing costs, utilization of our manufacturing facilities, the production mixtures of our sales, pricing of wafers from third party foundries and pricing of semiconductor raw materials. Capacity utilization affects our gross margin because we have certain fixed costs associated with our packaging and testing facilities at our Oregon fab and our Chongqing fabrication facility operated by the JV Company. We expect that in the long term our JV Company will reduce our cost of manufacturing. If we are unable to utilize our manufacturing facilities at a desired level, our gross margin may be adversely affected. In addition, from time to time, we may experience wafer capacity constraints, particularly at third party foundries, that may prevent us from meeting fully the demand of our customers. While we can mitigate such constraints by increasing and re-allocating capacity at our own fab, we may not be able to do so quickly or at sufficient level, which could adversely affect our financial conditions and results of operations.

Erosion and fluctuation of average selling price: Erosion of average selling prices of established products is typical in our industry. Consistent with this historical trend, we expect our average selling prices of existing products to decline in the future. However, in the normal course of business, we seek to offset the effect of declining average selling price by introducing new and higher value products, expanding existing products for new applications and new customers and reducing the manufacturing cost of existing products. These strategies may cause the average selling price of our products to fluctuate significantly from time to time, thereby affecting our financial performance and profitability.

The global, regional economic and PC market conditions: Because our products primarily serve consumer electronic applications, a deterioration of the global and regional economic conditions could materially affect our revenue and results of operations. For example, because a significant amount of our revenue is derived from sales of products in the personal computing

("PC") markets, such as notebooks, motherboards and notebook battery packs, a significant decline or downturn in the PC market can have a material adverse effect on our revenue and results of operations. Our revenue from the PC market accounted for approximately 39.3% and 43.8% of our total revenue for the three months ended September 30, 2019 and 2018, respectively. In the past, we have experienced a significant global decline in the PC markets due to continued growth of demand in tablets and smart phones, worldwide economic conditions and the industry inventory correction which had and may continue to have a material negative impact on the demand for our products, revenue, factory utilization, gross margin, our ability to resell excess inventory, and other performance measures. We have executed and continue to execute strategies to diversify our product portfolio, penetrate other market segments, including the consumer, communications and industrial markets, and improve gross margins and profit by implementing cost control measures. While making efforts to reduce our reliance on the computing market, we continue to support our computing business and capitalize on the opportunities in this market with a more focused and competitive PC product strategy.

Product introductions and customers' product requirements: Our success depends on our ability to introduce products on a timely basis that meet or are compatible with our customers' specifications and performance requirements. Both factors, timeliness of product introductions and conformance to customers' requirements, are equally important in securing design wins with our customers. As we accelerate the development of new technology platforms, we expect to increase the pace at which we introduce new products and seek and acquire design wins. Our failure to introduce new products on a timely basis that meet customers' specifications and performance requirements, particularly those products with major OEM customers, and our inability to continue to expand our serviceable markets, could adversely affect our financial performance, including loss of market share. We believe that the JV Transaction will increase and diversify our customer base, particularly in China, in the long term. The JV Company has continued ramping up its production of assembly and testing during the September 2019 quarter. In July 2019, we commenced limited mass production at the JV Company's 12-inch wafer fabrication facility. We expect to continue ramp up activities gradually. Even if we are able to ramp up the operation of the JV Company timely, we may not be successful in acquiring a sufficient number of new customers to offset additional costs due to various factors, including but are not limited to, competition from other semiconductor companies in the region, our lack of history and prior relationships with customers as a new entrant, difficulties in executing our joint venture strategies, lack of control over our operations and the general economic conditions in Chongqing and China.

Distributor ordering patterns, customer demand 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 outlook 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 by numerous factors, including global and regional economic conditions as well as the PC market 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. In recent periods, broad fluctuations in the semiconductor markets and the global and regional economic conditions, in particular the decline of the PC market conditions, have had a more significant impact on our results of operations than seasonality. Furthermore, our revenue may be impacted by the level of demand from our major customers due to factors outside of our control. If these major customers experience significant decline in the demand of their products, encounter difficulties or defects in their products, or otherwise fail to execute their sales and marketing strategies successfully, it may adversely affect our revenue and results of operations.

Principal line items of statements of operations

The following describes the principal line items set forth in our condensed consolidated statements of operations:

Revenue

We generate revenue primarily from the sale of power semiconductors, consisting of power discretes and power ICs. Historically, a majority of our revenue has been derived from power discrete products. Because our products typically have three-year to five-year 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 one of our subsidiaries.

Our product revenue is reported net of 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

monetary value of products purchased by the distributor during a specified period. At our discretion or upon our direct negotiations with the original design manufacturers ("ODMs") or original equipment manufacturers ("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, 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. We implemented a process to improve our factory capacity utilization rates by transferring more wafer production to our Oregon fab and reducing our reliance on outside foundries. While our utilization rates cannot be immune to the market conditions, our goal is to make them less vulnerable to market fluctuations. We believe our market diversification strategy and product growth will drive higher volume of manufacturing which will improve our factory utilization rates and gross margin in the long run.

Operating expenses

Our operating expenses consist of research and development, selling, general and administrative expenses and impairment of long-lived assets. We expect our operating expenses as a percentage of revenue to fluctuate from period to period as we continue to exercise cost control measures in response to the declining PC market as well as align our operating expenses to the revenue level.

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. We continue to invest in developing new technologies and products utilizing our own fabrication and packaging facilities as it is critical to our long-term success. We also evaluate appropriate investment levels and stay focused on new product introductions to improve our competitiveness. We expect that our research and development expenses will fluctuate from time to time.

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 fluctuate in the near future as we continue to exercise cost control measures as well as less pre-production costs due to the commencement of limited mass production in our JV Company started July 2019.

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 likely than not to be realized upon settlement with a taxing authority. 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 a valuation allowance against deferred tax assets if it is more likely than not that a portion of the deferred tax assets will not be realized, 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.

	$	117,802	$	115,072	$	2,730		2.4	%

Total revenue was $117.8 million for the three months ended September 30, 2019, an increase of $2.7 million, or 2.4%, as compared to $115.1 million for the same quarter last year. The increase was primarily due to an increase of $8.3 million in sales of power discrete, partially offset by a decrease of $3.7 million in sales of power IC products. The net increase in power discrete and power IC product sales was primarily due to a 20.8% increase in average selling price as compared to the same quarter last year due to a shift in product mix, partially offset by a 13.8% decrease in unit shipments. The decrease in revenue of packaging and testing services for the three months ended September 30, 2019 as compared to the same quarter last year was primarily due to decreased capacity to provide these services externally.

Cost of goods sold and gross profit



	Three Months Ended September 30,
	2019			2018			Change
	(in thousands)						(in thousands)			(in percentage)
Cost of goods sold	$	90,870		$	82,461		$	8,409		10.2	%
Percentage of revenue	77.1		%	71.7		%

Gross profit	$	26,932		$	32,611		$	(5,679	)	(17.4	)%
Percentage of revenue	22.9		%	28.3		%

Cost of goods sold was $90.9 million for the three months ended September 30, 2019, an increase of $8.4 million, or 10.2%, as compared to $82.5 million for the same quarter last year. The increase was primarily due to the limited mass production in our Chongqing joint venture and the 2.4% increase of revenue. Gross margin decreased by 5.4 percentage points to 22.9% for the three months ended September 30, 2019 as compared to 28.3% for the same quarter last year. The decrease in gross margin was primarily due to low capacity utilization to the commencement of limited mass production in our Chongqing joint venture during the three months ended September 30, 2019.

Research and development expenses

	(in thousands)				(in thousands)		(in percentage)
Research and development	$	12,368	$	11,384	$	984	8.6	%

Research and development expenses were $12.4 million for the three months ended September 30, 2019, an increase of $1.0 million, or 8.6%, as compared to $11.4 million for the same quarter last year. The increase was primarily attributable to a $0.5 million increase in product prototyping engineering expense as a result of increased engineering activities, a $0.2 million increase in professional services expense as a result of higher consulting fees, and a $0.3 million increase in depreciation expenses in the current quarter.

Selling, general and administrative expenses

	(in thousands)				(in thousands)			(in percentage)
Selling, general and administrative	$	15,185	$	20,352	$	(5,167	)	(25.4	)%

Selling, general and administrative expenses were $15.2 million for the three months ended September 30, 2019, a decrease of $5.2 million, or 25.4%, as compared to $20.4 million for the same quarter last year. The decrease was primarily due to the commencement of limited mass production at the 12-inch fab facility and continued ramping up the production of assembly and testing during the September 2019 quarter in the JV Company, resulting in significantly lower pre-production costs including a $4.5 million decrease in employee compensation and benefits expense and other costs. In addition, there was a $0.6 million decrease in share-based compensation expense due to an increase in stock awards canceled during the current quarter.

Interest income and other income (loss), net

	(in thousands)					(in thousands)			(in percentage)
Interest income and other income (loss), net	$	(998	)	$	262	$	(1,260	)	(480.9	)%

Interest income and other income (loss), net was primarily related to interest earned from cash and cash equivalents, as well as foreign exchange gains (losses). The decrease in interest income and other income (loss), net during the three months ended September 30, 2019 as compared to the same period last year was primarily due to higher foreign currency exchange losses as a result of recent depreciation of USD against RMB.

Interest expense



	Three Months Ended September 30,
	2019		2018			Change
	(in thousands)					(in thousands)		(in percentage)
Interest income (expenses)	$	171	$	(1,490	)	$	1,661	(111.5	)%

Interest expense was primarily related to bank borrowings. The decrease in interest expenses during the three months ended September 30, 2019 as compared to the same period last year was primarily due to a $2.7 million interest refund from the Chinese government in the JV Company, partially offset by higher interest expense as a result of an increase in bank borrowings.

Income tax expense



	Three Months Ended September 30,
	2019		2018		Change
	(in thousands)				(in thousands)			(in percentage)
Income tax expense	$	410	$	560	$	(150	)	(26.8	)%

For the three months ended September 30, 2019, the Company recognized income tax expense of approximately $0.4 million, compared to $0.6 million for the three months ended September 30, 2018. Excluding the discrete income tax items, the estimated effective tax rate for the three months ended September 30, 2019 was (27.3)% compared to (159.8)% for the three months ended September 30, 2018. The changes in the effective tax rate and tax expense between the periods resulted primarily from changes in the mix of earnings in various geographic jurisdictions between the current year and the same period of last year.

Liquidity and Capital Resources

Our principal need for liquidity and capital resources is to maintain sufficient working capital to support our operations and to invest adequate capital expenditures to grow of our business. To date, we finance our operations and capital expenditures primarily through funds generated from operations and borrowing under our term loan, financing lease and other debt agreements.

On September 23, 2019, the JV Company entered into a short term loan agreement with China Everbright bank in China. The JV Company can borrow up to Chinese Renminbi (RMB) 50.0 million or $7.1 million based on the currency exchange rate between RMB and U.S. Dollar on September 23, 2019 at varying interest rates, with either RMB or USD. Interest payments are due monthly and the entire principal is due no later than 90 days from each borrowing date. As of September 30, 2019, the outstanding balance under the loan was $0.8 million.

On March 21, 2019, the JV Company entered into a one-year loan agreement with China Everbright Bank in China to provide a loan for Chinese Renminbi (RMB) 20 million, or $3.0 million based on the currency exchange rate between RMB and U.S. Dollar on March 31, 2019 at a fixed interest rate of 5.44% per annum. Interest payments are due monthly with the entire principal due on March 21, 2020. As of September 30, 2019, the outstanding balance under the loan was 20 million RMB (equivalent of $2.8 million based on the currency exchange rate as of September 30, 2019).

On November 29 and December 4, 2018, the JV Company entered into two one-year loan agreements with China Merchant Bank in China to provide loans for Chinese Renminbi (RMB) 80 million and 20 million or $14.5 million in total based on currency exchange rate between RMB and U.S. Dollar on December 31, 2018, at varying interest rates, respectively. Interest payments are due monthly and quarterly with the entire principal due not later than December 18 and December 5, 2019, respectively. As of September 30, 2019, the outstanding balance under the loans were 80 million RMB and 20 million (equivalent of $14 million in total based on the currency exchange rate as of September 30, 2019).

On November 16, 2018, our subsidiary in China entered into a line of credit facility with Industrial and Commercial Bank of China, which expired in September 30, 2019. The purpose of the credit facility was to provide short-term borrowings. The Company could borrow up to approximately RMB 72 million or $10.3 million based on the currency exchange rate between RMB and U.S. Dollar on November 16, 2018. As of September 30, 2019, there was no outstanding balance under the line of credit. In October 2019, this line of credit was renewed with a maturity date of September 30, 2020.

On August 9, 2019, one of our wholly-owned subsidiaries (the "Borrower") entered into a factoring agreement with the Hongkong and Shanghai Banking Corporation Limited (“HSBC”), whereby the Borrower assigns certain of its accounts receivable with recourse. This factoring agreement allows us to borrow up to 70% of the net amount of eligible accounts receivable of the Borrower with a maximum amount of $30.0 million. The interest rate is based on one month LIBOR plus 1.75% per annum. This agreement, with certain financial covenants required, has no expiration date. The Company is the guarantor for this agreement. We are accounting for this transaction as a secured borrowing under the Transfer and Servicing of Financial Assets guidance. In addition, any cash held in the restricted bank account controlled by HSBC has a legal right of offset against the borrowing. We were in compliance with these covenants as of September 30, 2019. As of September 30, 2019, we had an outstanding balance of 2.0 million with 3.8% interest rate related to this secured borrowing and we had unused credit of approximately $28.0 million.

On May 9, 2018 (the “Effective Date”), the JV Company entered into a lease finance agreement and a security agreement (the “Agreements”) with YinHai Leasing Company and China Import/Export Bank (the “Lenders”). Pursuant to the Agreements, the Lenders agree to provide an aggregate of Chinese Renminbi (RMB) 400.0 million, or $62.8 million based on the currency exchange rate between the RMB and the U.S. Dollar on the Effective Date, of financing to the JV Company (the “Lease Financing”). The interest under the Lease Financing is accrued based on the China Base Rate multiplied by 1.15, or 5.4625% on the Effective Date. Under the Agreements, at the end of the five-year lease term, the Lenders agree to sell such equipment back to the JV Company for a nominal amount (RMB 1). The JV Company’s obligations under the Lease Financing are secured by the land and building owned by the JV Company (the “Collateral”). As of September 30, 2019, the outstanding balance of the Lease Financing was approximately $51.1 million based on the currency exchange rate as of September 30, 2019.

Rate multiplied by 1.1, or 5.39% on March 12, 2019. The loan requires quarterly interest payments. The principal payments are required to be paid every 6 months over the term of loan commencing in October 2019. This loan is secured by the buildings and certain equipment owned by the JV Company. As of September 30, 2019, the outstanding balance of the loan was 190 million (equivalent of $26.7 million based on the currency exchange rate as of September 30, 2019).

On May 1, 2018, Jireh entered into a credit agreement with the Bank that provided a term loan in an amount of $17.8 million. The obligation under the credit agreement is secured by certain assets of Jireh and guaranteed by the Company. The loan accrues interest based on a fixed rate of 5.04% based on the outstanding balance of the loan. The credit agreement contains customary restrictive covenants and includes certain financial covenants that require us to maintain, on a consolidated basis, specified financial ratios. We were in compliance with these covenants as of September 30, 2019. As of September 30, 2019, the outstanding balance of the term loan was $16.6 million.

On August 15, 2017, our Oregon subsidiary, Jireh Semiconductor Incorporated (“Jireh”), entered into a credit agreement with a financial institution (the “Bank”) that provides a term loan in an amount up to $30.0 million for the purpose of purchasing certain equipment for our fabrication facility located in Oregon. The obligation under the credit agreement is secured by substantially all assets of Jireh and guaranteed by the Company. The credit agreement has a five-year term and matures on August 15, 2022. In January 2018 and July 2018, Jireh drew down the loan in the amount of $13.2 million and $16.7 million, respectively. The loan accrues interest based on an adjusted London Interbank Offered Rate ("LIBOR") as defined in the credit agreement, plus a specified applicable margin in the range of 1.75% to 2.25%, based on the outstanding balance of the loan. The credit agreement contains customary restrictive covenants, including certain financial covenants that require the Company to maintain, on a consolidated basis, specified financial ratios and fixed charge coverage ratio. We were in compliance with these covenants as of September 30, 2019. As of September 30, 2019, the outstanding balance of the term loan was $22.4 million.

In September 2017, the Board of Directors approved a repurchase program (the “Repurchase Program”) that allowed us to repurchase our common shares from the open market pursuant to a pre-established Rule 10b5-1 trading plan or through privately negotiated transactions up to an aggregate of $30.0 million. The amount and timing of any repurchases under the Repurchase Program depend on a number of factors, including but not limited to, the trading price, volume, availability of our common shares and the amount of available cash reserve. Shares repurchased under this program are accounted for as treasury shares and the total cost of shares repurchased is recorded as a reduction of shareholders' equity. There is no guarantee that such repurchases under the Repurchase Program will enhance the value of our shares.

We did not repurchase any shares during the three months ended September 30, 2019. Since the inception of the prior repurchase program in 2010, we repurchased an aggregate of 6,784,648 shares from the open market for a total cost of $67.3 million, at an average price of $9.92 per share, excluding fees and related expenses. As of September 30, 2019, of the 6,784,648 repurchased shares, 140,328 shares with a weighted average repurchase price of $10.39 per share, were reissued at an average price of $5.50 per share pursuant to option exercises and vested restricted share units. We had $13.4 million remained available under the Repurchase Program as of September 30, 2019.

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 be certain 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 September 30, 2019 and June 30, 2019, we had $105.4 million and $124.3 million of cash, cash equivalents and restricted cash, respectively. Our cash, cash equivalents and restricted cash primarily consist of cash on hand, restricted cash,

and short-term bank deposits with original maturities of three months or less. Of the $105.4 million and $124.3 million cash, cash equivalents and restricted cash, $83.5 million and $68.2 million, respectively, are deposited with financial institutions outside the United States.

The following table shows our cash flows from operating, investing and financing activities for the periods indicated:



	Three Months Ended September 30,
	2019			2018
	(in thousands)
Net cash provided by (used in) operating activities	$	(1,227	)	$	17,987

Net decrease in cash, cash equivalents and restricted cash	$	(18,912	)	$	(18,370	)

Cash flows from operating activities

Net cash used in operating activities of $1.2 million for the three months ended September 30, 2019 resulted primarily from net loss of $1.9 million and net changes in assets and liabilities of $12.6 million, partially offset by non-cash expenses of $13.3 million. The non-cash expenses of $13.3 million primarily included $10.9 million of depreciation and amortization expenses and $2.4 million of share-based compensation expense. The net changes in assets and liabilities of $12.6 million were primarily due to a $5.8 million increase in inventories and a $15.0 million increase in accounts receivable from a one day delay of $9.2 million receivable payment from one of our major distributors due to the bank shut down on September 30, 2019 due to Typhoon Mitag in Taiwan, as well as increased billings in the current quarter as compared to the prior quarter, partially offset by a $3.8 million decrease in other current and long term assets due to decrease in advance payments to vendors, $0.8 million increase in accounts payable due to timing of payment, and a $3.7 million increase in accrued and other liabilities.

Net cash provided by operating activities of $18.0 million for the three months ended September 30, 2018 resulted primarily from non-cash expenses of $11.0 million as well as net changes in assets and liabilities of $7.9 million, partially offset by net loss of $0.9 million. The non-cash expenses of $11.0 million included $7.9 million of depreciation and amortization expenses and a $3.1 million of share-based compensation expense. The net changes in assets and liabilities of $7.9 million were primarily due to a $9.3 million increase in accrued and other liabilities, a $9.7 million increase in accounts payable due to timing of payment, and a $0.3 million decrease in other current and long term assets due to decrease in advance payments to vendors, partially offset by a $7.9 million increase in inventories to meet the market demand, and a $3.6 million increase in accounts receivable from timing of billings and collection of payments.

Cash flows from investing activities

Net cash used in investing activities of $15.8 million for the three months ended September 30, 2019 was primarily attributable to $15.8 million purchases of property and equipment, including $7.5 million purchased by the JV Company.

Net cash used in investing activities of $49.5 million for the three months ended September 30, 2018 was primarily attributable to $49.5 million purchases of property and equipment, including $34.3 million purchase in the JV Company during the quarter.

Cash flows from financing activities

Net cash used in financing activities of $1.1 million for the three months ended September 30, 2019 was primarily attributable to $2.1 million in repayments of borrowings, $1.7 million in payment of finance lease obligations, and $0.1 million in common shares acquired to settle withholding tax related to vesting of restricted stock units, partially offset by $2.8 million proceeds from borrowings.

Net cash provided by financing activities of $14.7 million for the three months ended September 30, 2018 was primarily attributable to $16.7 million proceeds from borrowings and $0.1 million of proceeds from exercise of stock options, partially offset by $1.5 million for repurchase of our common shares under the repurchase program, $0.2 million in payment of finance lease obligations, $0.2 million in repayments of borrowings, and $0.1 million in common shares acquired to settle withholding tax related to vesting of restricted stock units.

Commitments

See Note 10 of the Notes to the Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q for a description of commitments.

Off-Balance Sheet Arrangements

As of September 30, 2019, we had no material off-balance sheet arrangements as defined in Regulation S-K 303(a)(4)(ii) arrangements.

Contractual Obligations

There were no material changes outside of our ordinary course of business in our contractual obligations from those disclosed in our Annual Report on Form 10-K for the fiscal year ended June 30, 2019.

Recent Accounting Pronouncements

See Note 1 of the Notes to the Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q for a description of recent accounting pronouncements, including the expected dates of adoption and estimated effects on results of operations and financial condition, which is incorporated herein by reference.

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, 2019, filed with the SEC on August 23, 2019.

ITEM 4. CONTROLS AND PROCEDURES

Management's Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”)), as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of September 30, 2019 have been designed and are functioning effectively to provide reasonable assurance that the information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

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, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitation on Effectiveness of Controls

While our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance that their respective objectives will be met, we do not expect that our disclosure controls and procedures or our internal control over financial reporting are or will be capable of preventing or detecting all errors and all fraud. Any control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met.

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. 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, we could incur significant costs in the defense thereof or could suffer adverse effects on its operations.

ITEM 1A. RISK FACTORS

Item 1A of Part I of our Annual Report on Form 10-K for the year ended June 30, 2019, filed with the SEC on August 23, 2019, contains risk factors identified by the Company. Except as noted below, there have been no material changes to the risk factors we previously disclosed in our filings with the SEC. 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.

Proposed new additional tariffs on imported goods from China could adversely affect our business operations.

The President of the United States has recently stated that the U.S. would delay a proposed increase of the tariff rate on an additional $250 billion of Chinese goods from 25% to 30% that had been planned for October 15, 2019, and that the U.S. plans to impose 15% tariffs on an additional $160 billion of a wide range of goods and materials imported from China by December 15, 2019, with tariffs thus potentially affecting nearly all goods imported from China. These goods, absent exemptions, would include products and applications, including consumer electronics, that incorporate our power discrete and power IC products. In response, China has imposed tariffs on certain American products, and may take additional actions if these additional U.S. tariffs are imposed. The continuing trade war could have significant adverse effects on world trade and the world economy. While it is too early to predict if the proposed additional U.S. tariffs will be imposed, in view of ongoing discussions between the Chinese and U.S. governments, the ultimate level of such tariffs, the ultimate scope of them, or how the proposed additional tariffs will impact our business, we believe that the imposition of the proposed additional tariffs by the U.S. government on products incorporating our power semiconductors could deter our U.S. customers from purchasing our products originating from China. If so, this could reduce demand for our power semiconductor products or result in pricing adjustments that would lower our gross margin, which could have a material adverse effect on our business and results of operations.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In September 2017, the Board of Directors approved a repurchase program (the “Repurchase Program”), that allows us to repurchase our common shares from the open market pursuant to a pre-established Rule 10b5-1 trading plan or through privately negotiated transactions up to an aggregate of $30.0 million. The amount and timing of any repurchases under the Repurchase Program depend on a number of factors, including but not limited to, the trading price, volume and availability of our common shares and our available cash reserve. Shares repurchased under this program are accounted for as treasury shares and the total cost of shares repurchased is recorded as a reduction of shareholders' equity. There is no guarantee that such repurchases under the Repurchase Program will enhance the value of our shares. During the three months ended September 30, 2019, we did not repurchase any shares under the Repurchase Program. As of September 30, 2019, approximately $13.4 million remained available under the Repurchase Program.
