NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation

The accompanying unaudited condensed consolidated financial statements of GSI Technology, Inc. and its subsidiaries (“GSI” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission.  Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for annual financial statements.  These interim financial statements contain all adjustments (which consist of only normal, recurring adjustments) that are, in the opinion of management, necessary to state fairly the interim financial information included therein.  The Company believes that the disclosures are adequate to make the information not misleading.  However, these financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2017.

The consolidated results of operations for the nine months ended December 31, 2017 are not necessarily indicative of the results to be expected for the entire fiscal year.

Significant accounting policies

The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2017.

Recent accounting pronouncements

In May 2017, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2017-09, “Scope of Modification Accounting”.  ASU 2017-09 amends the scope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. This guidance clarifies that an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the fair value of the award, (ii) the vesting conditions of the award, and (iii) the classification of the award as an equityinstrument or liability instrument. The standard is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017, including adoption in any interim period.  The Company is currently evaluating the impact of this standard on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The standard eliminates the second step in the goodwill impairment test which requires an entity to determine the implied fair value of the reporting unit’s goodwill.  Instead, an entity should recognize an impairment loss if the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, with the impairment loss not to exceed the amount of goodwill allocated to the reporting unit. The standard is effective for annual and interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019, with early adoption permitted.  The Company does not anticipate the adoption of this guidance to have a material impact on its consolidated financial statements and related disclosures.

6

In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash”. ASU 2016-18 requires entities to include in their cash and cash-equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash and restricted cash equivalents. As a result, companies will no longer present transfers between cash and cash equivalents, and restricted cash and restricted cash equivalents in the statement of cash flows. The guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact this new guidance will have on its consolidated statement of cash flows.

In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.” ASU 2016-16 requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs and eliminates the exception for an intra-entity transfer of an asset other than inventory.  The Company adopted ASU 2016-16 in the quarter ended June 30, 2017.  ASU 2016-16 is applied on a modified retrospective basis in the period of adoption.   The adoption of this guidance resulted in a derecognition of a prepaid tax asset of $595,000 related to a prior period intra-entity asset transfer, with an offsetting reduction to retained earnings.  Because of the Company’s valuation allowance in the United States, there was no change to the Company’s net deferred tax assets.  The derecognition of the prepaid tax asset as of April 1, 2017 decreased the Company’s income tax expense by $11,000 in each of the quarters ended June 30, 2017, September 30, 2017 and December 31, 2017 and is projected to decrease the Company’s fiscal 2018 tax expense by $43,000.

In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments”. ASU 2016-15 adds or clarifies guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. The amendments in the update provide guidance on eight specific cash flow issues, and are effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The amendments to the guidance should be applied using a retrospective transition method for each period presented and, if it is impracticable to apply all of the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company is currently evaluating the impact this new guidance will have on its consolidated statement of cash flows.

In June 2016, the FASB issued ASU 2016-13,  “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For trade and other receivables, loans, and other financial instruments, the Company will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted beginning April 1, 2019. Application of the amendments is through a cumulative-effect adjustment to retained earnings as of the effective date. The Company is currently evaluating the impact of this standard on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The Company adopted ASU 2016-09 in the quarter ended June 30, 2017.  The Company has elected to continue to estimate forfeitures as part of the compensation cost of equity awards.  ASU 2016-09 is applied prospectively to all excess tax benefits and tax deficiencies resulting from settlements after the date of adoption.  The adoption of ASU 2016-09 resulted in an increase to the net operating loss carryforward deferred tax asset and a corresponding increase in the valuation allowance of $654,000 attributable to excess tax benefits not previously recognized as they did not reduce income taxes payable.

7

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. All leases create an asset and a liability for the lessee in accordance with FASB Concepts Statement No. 6, “Elements of Financial Statements,” and, therefore, recognition of those lease assets and lease liabilities represents a change of previous GAAP, which did not require lease assets and lease liabilities to be recognized for most leases.  This ASU is effective for annual and interim periods beginning after December 15, 2018.  Early adoption is permitted. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous GAAP. Although the Company is currently evaluating the impact the pronouncement will have on its consolidated financial statements and related disclosures, the Company expects that most of its operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets upon adoption.

In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income and simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. The accounting standard update also updates certain presentation and disclosure requirements. This accounting standard update will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years,and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” This standard update intends to simplify the subsequent measurement of inventory, excluding inventory accounted for under the last-in, first-out or the retail inventory methods. The update replaces the current lower of cost or market test with a lower of cost and net realizable value test. Under the current guidance, market could be replacement cost, net realizable value or net realizable value less an approximately normal profit margin. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.  The Company adopted ASU 2015-11 in the quarter ended June 30, 2017.  Implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)" and has subsequently issued several supplemental and/or clarifying ASUs (collectively, "ASC 606"). The new accounting standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The accounting standard is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2017. The Company plans to adopt ASC 606 on April 1, 2018 using the modified retrospective transition method with the cumulative effect of initial adoption, if any, recognized in opening retained earnings on the adoption date. Almost all of the Company’s purchase orders, contracts or purchase agreements do not contain performance obligations other than delivery of the agreed upon product, with title transfer occurring at the time of shipment subject to estimated allowance for distributor price adjustments and rights of return. Thus, the Company generally recognizes revenue upon shipment of the product. The Company has historically deferred recognition of revenue on shipments to its distributors that have ship from stock and debit and price protection rights due to a lack of a fixed and determinable price that could be reasonably estimated. The Company has been revising certain of its distribution agreements to eliminate ship from stock and debits and price protection in order to eliminate any uncertainty in regards to a final selling price and to establish a selling price that is fixed and determinable at the time of shipment to the distributor.  Assuming all other revenue recognition criteria have been met, it is likely that the new guidance would require the Company to recognize revenue and cost relating to distributor sales upon shipment to the distributor, subject to estimated allowance for distributor price adjustments and rights of return. The Company is currently in the process of assessing the impact this guidance is expected to have upon adoption, which includes determining the impact of the new guidance on the Company’s revenue recognition practices, business processes, internal controls and the additional disclosures which may be required upon the adoption of ASC 606.

NOTE 4—GOODWILL

Goodwill represents the difference between the purchase price and the estimated fair value of the identifiable assets acquired and liabilities assumed in a business combination. The Company tests for goodwill impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the asset is more likely than not impaired. The Company has one reporting unit. The Company assesses goodwill for impairment on an annual basis on the last day of February in the fourth quarter of its fiscal year.

The Company had a goodwill balance of $8.0 million as of both March 31, 2017 and December 31, 2017. The goodwill resulted from the acquisition of MikaMonu Group Ltd. in fiscal 2016.

The Company utilized a two-step quantitative analysis to complete its annual impairment test during the fourth quarter of fiscal 2017 and concluded that there was no impairment, as the fair value of its sole reporting unit exceeded its carrying value. The Company determined that the second step of the impairment test was not necessary. No triggering event took place subsequent to the fiscal 2017 annual assessment that necessitated a quantitative impairment analysis for the Company’s one reporting unit.

NOTE 5—INCOME TAXES

The current portion of the Company’s unrecognized tax benefits was $0 at both December 31, 2017 and March 31, 2017. The long-term portion at December 31, 2017 and March 31, 2017 was $823,000 and $244,000, respectively, of which the timing of the resolution is uncertain.  As of December 31, 2017, $1.3 million of unrecognized tax benefits had been recorded as a reduction to net deferred tax assets.  As of December 31,2017 and March 31, 2017, the Company’s net deferred tax assets of $5.6 million and $8.9 million, respectively, were subject to a full valuation allowance.

On December 22, 2017, the “Tax Cuts and Jobs Act” ("H.R. 1") was signed into law, significantly impacting several sections of the Internal Revenue Code. This new law includes significant changes to the U.S. corporate income tax system, including a permanent reduction in the corporate income tax rate from 35% to 21%, limitations on the deductibility of interest expense and executive compensation and the transition of U.S. international taxation from a worldwide tax system to a territorial tax system.  The Company remeasured all deferred tax assets and liabilities as of December 22, 2017, based on the provisions of H.R. 1. This new legislation resulted in a estimated tax provision of $639,000 in the quarter ended December 31, 2017 related to the transition tax associated with deemed repatriation of foreign earnings. In addition, as a result of provisions in the new

12

legislation related to indefinite lived net operating loss carryovers and the refundability of minimum tax credit carryovers, the Company recorded a deferred tax benefit related to a valuation allowance release of $99,000 in the quarter ended December 31, 2017. Finally, the Company recorded a liability for taxes payable of $68,000 at December 31, 2017 that will be paid over a period of up to eight years. 

This original estimate may be materially impacted by a number of additional considerations, including but not limited to the issuance of the final regulations, the Company’s ongoing analysis of the new law and the Company’s actual earnings for the fiscal year ending March 31, 2018.

Management believes that within the next twelve months the Company will have no reduction in uncertain tax benefits, including interest and penalties, related to positions taken with respect to credits and loss carryforwards on previously filed tax returns.

The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the provision for income taxes in the Condensed Consolidated Statements of Operations.

The Company is subject to taxation in the United States and various state and foreign jurisdictions.  Fiscal years 2013 through 2017 remain open to examination by federal tax authorities, and fiscal years 2011 through 2017 remain open to examination by California tax authorities.

The Company’s estimated annual effective income tax rate was approximately  (13.7%) and 7.4% as of December 31, 2017 and 2016, respectively. The annual effective tax rates as of December 31, 2017 and 2016 vary from the United States statutory income tax rate primarily due to valuation allowances in the United States, whereby pre-tax losses do not result in the recognition of corresponding income tax benefits and expenses, the foreign tax differential, and the impact of new tax reform.

NOTE 6—FINANCIAL INSTRUMENTS

Fair value measurements

Authoritative accounting guidance for fair value measurements provides a framework for measuring fair value and related disclosures.  The guidance applies to all financial assets and financial liabilities that are measured on a recurring basis.  The guidance requires fair value measurement to be classified and disclosed in one of the following three categories:

Level 1: Valuations based on quoted prices in active markets for identical assets and liabilities.  The fair value of available-for-sale securities included in the Level 1 category is based on quoted prices that are readily and regularly available in an active market.  As of December 31, 2017, the Level 1 category included money market funds of$9.5 million, which were included in cash and cash equivalents on the Condensed Consolidated Balance Sheets.

Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly. The fair value of available-for-sale securities included in the Level 2 category is based on the market values obtained from an independent pricing service that were evaluated using pricing models that vary by asset class and may incorporate available trade, bid and other market information and price quotes from well-established independent pricing vendors and broker-dealers. As of December 31, 2017, the Level 2 category included short-term investments of $17.0 million and long-term investments of $8.2 million, which were comprised of certificates of deposit, corporate debt securities and government and agency securities.

Level 3: Valuations based on inputs that are unobservable and involve management judgment and the reporting entity’s own assumptions about market participants and pricing.  As of December 31, 2017, the Company’s Level 3 financial instruments measured at fair value on the Condensed Consolidated Balance Sheets consisted of the contingent consideration liability related to the acquisition of MikaMonu. The fair value of the contingent consideration liability was initially determined as of the acquisition date using unobservable inputs.  These inputs include the estimated amount and timing of future cash flows, the probability of success (achievement

13

of the various contingent events) and a risk-adjusted discount rate of approximately 14.8% used to adjust the probability-weighted cash flows to their present value.  Subsequent to the acquisition date, at each reporting period, the contingent consideration liability is re-measured to fair value with changes recorded in selling, general and administrative expenses in the Consolidated Statements of Operations. The change in fair value for the three month and nine month periods ended December 31, 2017 were $41,000 and $121,000, respectively.

The fair value of financial assets measured on a recurring basis is as follows (in thousands):

Short-term and long-term investments

All of the Company’s short-term and long-term investments are classified as available-for-sale.  Available-for-sale debt securities with maturities greater than twelve months are classified as long-term investments when they are not intended for use in current operations.  Investments in available-for-sale securities are reported at fair value with unrecognized gains (losses), net of tax, as a component of accumulated other comprehensive income (loss) in the Condensed Consolidated Balance Sheets.  The Company had money market funds of $9.5 million and $6.3 million at December 31, 2017 and March 31, 2017, respectively, included in cash and cash equivalents on the Condensed Consolidated Balance Sheets.  The Company monitors its investments for impairment periodically and records appropriate reductions in carrying values when declines are determined to be other-than-temporary.

The Company’s investment portfolio consists of both corporate and governmental securities that have a maximum maturity of three years. All unrealized gains and losses are due to changes in interest rates and bond yields.  Subject to normal credit risks, the Company has the ability to realize the full value of all these investments upon maturity.

The deferred tax asset related to unrecognized gains and losses on short-term and long-term investments was $21,000 and $17,000 at December 31, 2017 and March 31, 2017, respectively.

As of December 31, 2017, contractual maturities of the Company’s available-for-sale investments were as follows:

			Fair
	Cost		Value
	(In thousands)
Maturing within one year	$	17,073	$	17,030
Maturing in one to three years		8,250		8,199

NOTE 7—COMMITMENTS AND CONTINGENCIES

Indemnification obligations

The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify the other party with respect to certain matters. Typically, these obligations arise in the context of contracts entered into by the Company, under which the Company 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 and certain intellectual property rights. In each of these circumstances, payment by the Company is 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 claims. Further, the Company’s obligations under these agreements may be limited in terms of 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.

It is not possible to predict the maximum potential amount of future payments that may be required under these or similar agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material effect on its business, financial condition, cash flows or results of operations.

Product warranties

The Company warrants its products to be free of defects generally for a period of three years. The Company estimates its warranty costs based on historical warranty claim experience and includes such costs in cost of revenues. Warranty costs and the accrued warranty liability were not material as of December 31, 2017 and March 31, 2017 and for the three months and nine months ended December 31, 2017 or 2016.

NOTE 8—STOCK-BASED COMPENSATION

As of December 31, 2017, 4,575,111 shares of common stock were available for grant under the Company’s 2016 Equity Incentive Plan.

The following table summarizes the Company’s stock option activities for the nine months ended December 31, 2017:

The following table summarizes stock-based compensation expense by line item in the Condensed Consolidated Statements of Operations, all relating to employee stock plans:

	Three Months Ended December 31,				Nine Months Ended December 31,

Selling, general and administrative		170		100		492		438
Total	$	535	$	429	$	1,521	$	1,359

As stock-based compensation expense recognized in the Condensed Consolidated Statement of Operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures in accordance with authoritative guidance.  The Company estimates forfeitures at the time of grant and revises the original estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

No tax benefit related to stock-based compensation was recognized in the three months or nine months ended December 31, 2017 or December 31, 2016 due to a full valuation allowance. There were no windfall tax benefits realized from exercised stock options in either of these periods.   Compensation cost capitalized within inventory at December 31, 2017 was immaterial. As of December 31, 2017, the Company’s total unrecognized compensation cost was $4.2 million, which will be recognized over a weighted average period of 2.18 years. The Company calculated the fair value of stock-based awards in the periods presented using the Black-Scholes option pricing model and the following weighted average assumptions:

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Quarterly Report on Form 10-Q, and in particular the following Management’s Discussion and Analysis of Financial Condition and Results of Operations, includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).  These forward-looking statements involve risks and uncertainties.  Forward-looking statements are identified by words such as “anticipates,” “believes,” “expects,” “intends,” “may,” “will,” and other similar expressions.  In addition, any statements which refer to expectations, projections, or other characterizations of future events or circumstances are forward-looking statements.  Actual results could differ materially from those projected in the forward-looking statements as a result of a number of factors, including those set forth in this report under “Risk Factors,” those described elsewhere in this report, and those described in our other reports filed with the Securities and Exchange Commission (“SEC”).  We caution you not to place undue reliance on these forward-looking statements, which speak only as of the date of this report, and we undertake no obligation to update these forward-looking statements after the filing of this report. You are urged to review carefully and consider our various disclosures in this report and in our other reports publicly disclosed or filed with the SEC that attempt to advise you of the risks and factors that may affect our business.

Overview

We are a fabless semiconductor company that designs, develops and markets static random access memories, or SRAMs, that operate at speeds of less than 10 nanoseconds, which we refer to as Very Fast SRAMs, and low latency dynamic random access memories, or LLDRAMs, primarily for the networking and telecommunications markets. We are subject to the highly cyclical nature of the semiconductor industry, which has experienced significant fluctuations, often in connection with fluctuations in demand for the products in which semiconductor devices are used. Our revenues have been substantially impacted by significant fluctuations in sales to our largest customer, Nokia (Alcatel-Lucent), and Cisco Systems, which was our largest customer in years past. We expect that future direct and indirect sales to these two customers will continue to fluctuate significantly on a quarterly basis. The worldwide financial crisis and the resulting economic impact on the end markets we serve have adversely impacted our financial results since the second half of fiscal 2009, and we expect that the unsettled global economic environment will continue to affect our operating results in future periods. However, with no debt, substantial liquidity and a history of positive cash flows from operations, we believe we are in a better financial position than many other companies of our size.

Revenues.    Our revenues are derived primarily from sales of our Very Fast SRAM products. Sales to networking and telecommunications OEMs accounted for 63% to 66% of our net revenues during our last three fiscal years. We also sell our products to OEMs that manufacture products for defense applications such as radar and guidance systems, for professional audio applications such as sound mixing systems, for test and measurement applications such as high-speed testers, for automotive applications such as smart cruise control and voice recognition systems, and for medical applications such as ultrasound and CAT scan equipment.

As is typical in the semiconductor industry, the selling prices of our products generally decline over the life of the product. Our ability to increase net revenues, therefore, is dependent upon our ability to increase unit sales volumes of existing products and to introduce and sell new products with higher average selling prices in quantities sufficient to compensate for the anticipated declines in selling prices of our more mature products.  Although we expect the average selling prices of individual products to decline over time, we believe that, over the next several quarters, our overall average selling prices will increase due to a continuing shift in product mix to a higher percentage of higher price, higher density products. Our ability to increase unit sales volumes is dependent primarily upon increases in customer demand but, particularly in periods of increasing demand, can also be affected by our ability to increase production through the availability of increased wafer fabrication capacity from Taiwan Semiconductor Manufacturing Company, or TSMC, and Powerchip, our wafer suppliers, and our ability to increase the number of good integrated circuit die produced from each wafer through die size reductions and yield enhancement activities.

We may experience fluctuations in quarterly net revenues for a number of reasons. Historically, orders on hand at the beginning of each quarter are insufficient to meet our revenue objectives for that quarter and are generally cancelable up to 30 days prior to scheduled delivery. Accordingly, we depend on obtaining and shipping

19

orders in the same quarter to achieve our revenue objectives. In addition, the timing of product releases, purchase orders and product availability could result in significant product shipments at the end of a quarter. Failure to ship these products by the end of the quarter may adversely affect our operating results. Furthermore, our customers may delay scheduled delivery dates and/or cancel orders within specified timeframes without significant penalty.

We sell our products through our direct sales force, international and domestic sales representatives and distributors. Historically, revenues from product sales, except for sales to distributors that have price protection and ship from stock and debit rights, are generally recognized upon shipment, net of sales returns and allowances. Sales to consignment warehouses, who purchase products from us for use by contract manufacturers, are recorded upon delivery to the contract manufacturer. Sales to distributors that have price protection and ship from stock and debit rights are recorded as deferred revenues for financial reporting purposes and recognized as revenues when the products are resold by the distributors to the OEM. Sales to certain distributors are made under agreements allowing for returns or credits under certain circumstances. We therefore defer recognition of revenue on sales to those distributors under these terms until products are resold by the distributor. We have been revising certain distribution agreements to eliminate ship from stock and debits and price protection. Under these revised distribution agreements, we recognized additional revenue of $848,000 for the three months ended December 31, 2017 upon shipment of the product as the price was fixed and determinable.

Nokia (Alcatel-Lucent) was our largest customer in fiscal 2017, 2016 and 2015.  Nokia (Alcatel-Lucent) purchases products directly from us and through contract manufacturers and distributors.  Purchases by Nokia (Alcatel-Lucent) represented approximately 36%, 41%, 32% and 25% of our net revenues in the nine months ended December 31, 2017 and in fiscal 2017,  2016 and 2015, respectively. Cisco Systems, our largest OEM customer prior to fiscal 2014, purchases our products primarily through its consignment warehouse, Wintec Industries Inc., and also purchases some products through its contract manufacturers and directly from us. Based on information provided to us by Cisco Systems' consignment warehouses and contract manufacturers, purchases by Cisco Systems represented approximately 6%,9%, 9% and 13% of our net revenues in the nine months ended December 31, 2017 and in fiscal 2017,  2016 and 2015, respectively.  Our revenues have been substantially impacted by significant fluctuations in sales to Nokia (Alcatel-Lucent) and Cisco Systems, and we expect that future direct and indirect sales to these two customers will continue to fluctuate substantially on a quarterly basis and that such fluctuations may significantly affect our operating results in future periods.  To our knowledge, none of our other OEM customers accounted for more than 10% of our net revenues in the nine months ended December 31, 2017 or in fiscal 2017,  2016 or 2015.

Cost of Revenues.    Our cost of revenues consists primarily of wafer fabrication costs, wafer sort, assembly, test and burn-in expenses, the amortized cost of production mask sets, stock-based compensation and the cost of materials and overhead from operations. All of our wafer manufacturing and assembly operations, and a significant portion of our wafer sort testing operations, are outsourced. Accordingly, most of our cost of revenues consists of payments to TSMC, Powerchip and independent assembly and test houses. Because we do not have long-term, fixed-price supply contracts, our wafer fabrication and other outsourced manufacturing costs are subject to the cyclical fluctuations in demand for semiconductors. Cost of revenues also includes expenses related to supply chain management, quality assurance, and final product testing and documentation control activities conducted at our headquarters in Sunnyvale, California and our branch operations in Taiwan.

Gross Profit.    Our gross profit margins vary among our products and are generally greater on our higher density products and, within a particular density, greater on our higher speed and industrial temperature products. We expect that our overall gross margins will fluctuate from period to period as a result of shifts in product mix, changes in average selling prices and our ability to control our cost of revenues, including costs associated with outsourced wafer fabrication and product assembly and testing.

Research and Development Expenses.    Research and development expenses consist primarily of salaries and related expenses for design engineers and other technical personnel, the cost of developing prototypes, stock-based compensation and fees paid to consultants. We charge all research and development expenses to operations as incurred. We charge mask costs used in production to cost of revenues over a 12-month period. However, we charge costs related to pre-production mask sets, which are not used in production, to research and development expenses at the time they are incurred. These charges often arise as we transition to new process technologies and, accordingly, can cause research and development expenses to fluctuate on a quarterly basis. We believe that continued investment in research and development is critical to our long-term success, and we expect to continue to devote

20

significant resources to product development activities. In particular, we are devoting substantial resources to the development of a new category of in-place associative computing products based on patented technology obtained in our acquisition of MikaMonu in November 2015.  Accordingly, we expect that our research and development expenses will continue to be substantial in future periods and may lead to operating losses in some periods. Such expenses as a percentage of net revenues may fluctuate from period to period.

Selling, General and Administrative Expenses.     Selling, general and administrative expenses consist primarily of commissions paid to independent sales representatives, salaries, stock-based compensation and related expenses for personnel engaged in sales, marketing, administrative, finance and human resources activities, professional fees, costs associated with the promotion of our products and other corporate expenses. We expect that our sales and marketing expenses will increase in absolute dollars in future periods if we are able to grow and expand our sales force but that, to the extent our revenues increase in future periods, these expenses will generally decline as a percentage of net revenues. We also expect that, in support of any future growth that we are able to achieve, general and administrative expenses will generally increase in absolute dollars.

Net Revenues. Net revenues decreased by 3.2% from $11.5 million in the three months ended December 31, 2016 to $11.1 million in the three months ended December 31, 2017 and by 16.8% from $37.8 million in the nine months ended December 31, 2016 to $31.5 million in the nine months ended December 31, 2017. The reduction in both periods reflected the continuing weakness in the global networking and telecommunications markets and, in particular, continued weakness in Asia. Direct and indirect sales to Nokia (Alcatel-Lucent), currently our largest customer, decreased from $4.5 million in the three months ended December 31, 2016 to $3.9 million in the three months ended December 31, 2017 and from $15.7 million in the nine months ended December 31, 2016 to $11.2 million in the nine months ended December 31, 2017. The decrease in the each period reflected a continuing inventory correction by Nokia (Alcatel-Lucent) to reduce inventory levels to align them with production requirements.Direct and indirect sales to Cisco Systems, our largest customer prior to 2014,  decreased from $1.1 million in the three months ended December 31, 2016 to $565,000 in the three months ended December 31, 2017 and from$3.6 million in the nine months ended December 31, 2016 to $1.9 million in the nine months ended December 31, 2017 reflecting softness in the market for its switches and routers that incorporate our products. Shipments of our SigmaQuad product line accounted for 54.5% of total shipments in the three months ended December 31, 2017 compared to 54.2% of total shipments in the three months ended December 31, 2016 and 48.2% of total shipments in the nine months ended December 31, 2017 compared to 55.8% of total shipments in the nine months ended December 31, 2016. The decline in SigmaQuad shipments in each period is primarily due to the decline in sales to Nokia (Alcatel-Lucent) discussed above.

Cost of Revenues. Cost of revenues increased by 9.1% from $5.0 million in the three months ended December 31, 2016 to $5.4 million in the three months ended December 31, 2017 and decreased by 11.1% from $17.2 million in the nine months ended December 31, 2016 to $15.3 million in the three months ended December 31, 2017.The increase in cost of revenues in the current three month period is primarily due to changes in amounts charged to cost of revenue for potentially excess inventory and changes in the mix of product shipped during each period. The decrease in cost of revenues in the nine month period was primarily due to the decrease in net revenues discussed above. Cost of revenues included stock-based compensation expense of $73,000 and $78,000 for the three months ended December 31, 2017 and 2016, respectively, and $186,000 and $209,000 for the nine months ended December 31, 2017 and 2016, respectively.

Gross Profit. Gross profit decreased by 12.6% from $6.5 million in the three months ended December 31, 2016 to $5.7 million in the three months ended December 31, 2017 and by 21.5% from $20.6 million in the nine months ended December 31, 2016 to $16.1 million in the nine months ended December 31, 2017. Gross margin decreased from 56.6% in the three months ended December 31, 2016 to 51.0% in the three months ended December 31, 2017 and from 54.4% in the nine months ended December 31, 2016 to 51.3% in the nine months ended December 31, 2017. The decrease in gross profit in the three months and nine months ended December 31, 2017 is primarily related to the decreases in net revenues discussed above and a provision for excess and obsolete inventories of $427,000 for the three months ended December 31, 2017 compared to $158,000 in the three months ended December 31, 2016 and a provision for excess and obsolete inventories of $1.2 million for the nine months ended December 31, 2017 compared to $491,000 in the nine months December 31, 2016.  The decreases in gross margin are primarily related to changes in the mix of products and customers and changes in the provision for excess and obsolete inventories discussed above.

Research and Development Expenses. Research and development expenses increased by 11.0% from $3.8 million in the three months ended December 31, 2016 to $4.2 million in the three months ended December 31, 2017.  This increase was primarily due to an increase of $261,000 in payroll related expenses related to our associative processor development activities. Research and development expenses included stock-based compensation expense of $292,000 and $251,000 for the three months ended December 31, 2017 and 2016, respectively. Research and development expenses increased from $11.6 million in the nine months ended December 31, 2016 to $12.7 million in the nine months ended December 31, 2017.The increase was primarily due to an increase of $1.3 million in payroll related expenses partially offset by a decrease of $564,000 for purchased IP,  both primarily related to our associative processor development activities.   Research and development expenses included stock-based compensation expense of $843,000 and $712,000 for the nine months ended December 31, 2017 and 2016, respectively.

Selling, General and Administrative Expenses.Selling, general and administrative expenses were essentially unchanged at $2.4 million in the three months ended December 31, 2016 compared to $2.5 million in the three months ended December 31, 2017.Increases in stock-based compensation expenses, professional fees and independent sales representative commissions were primarily offset by a decrease in payroll related expenses. Selling, general and administrative expenses included stock-based compensation expense of $170,000 and $100,000 for the three months ended December 31, 2017 and 2016, respectively. Selling, general and administrative expenses decreased 2.4% from $8.0 million in the nine months ended December 31, 2016 to $7.8 million in the nine months ended December 31, 2017.This decrease was primarily related to a decrease in payroll related expenses of $174,000 and a lesser decrease in professional fees. Selling, general and administrative expenses included stock-based compensation expense of $492,000 and $438,000 for the nine months ended December 31, 2017 and 2016, respectively.

Interest and Other Income (Expense), Net. Interest and other income (expense), net increased 62.3% from income of $61,000 in the three months ended December 31, 2016 to $99,000 in the three months ended December 31, 2017.  Interest income increased by $32,000 due to higher interest rates received on our cash and short-term and long-term investments. Foreign exchange losses were $20,000 for the three months ended December 31, 2016 as compared to $14,000 for the three months ended December 31, 2017.Interest and other income (expense), net increased 1.7% from income of $295,000 in the nine months ended December 31, 2016 to $300,000 in the nine months ended December 31, 2017.  Interest income increased by $82,000 due to higher interest rates received on our cash and short-term and long-term investments. Foreign exchange gains were  $68,000 for the nine months ended

22

December 31, 2016 as compared to a loss  $9,000 for the nine months ended December 31, 2017. The exchange gains and losses in each period were related to our Taiwan branch operations and our operations in Israel.

Provision for (benefit from) Income Taxes. The benefit for income taxes increased from $53,000 in the three months ended December 31, 2016 to a provision of $590,000 in the three months ended December 31, 2017 and the provision increased 1,025.0% from $64,000 in the nine months ended December 31, 2016 to $720,000 in the nine months ended December 31, 2017. These changes were primarily due to a tax provision of $639,000 related to the transition tax associated with deemed repatriation of foreign earnings and the re-measurement of deferred tax assets and liabilities based on the provisions of H.R. 1 recorded in the quarter ended December 31, 2017 as well as from fluctuations in the relative mix of income among our operating jurisdictions.

Net Income (Loss).  Net income was  $348,000 in the three months ended December 31, 2016 compared to a net loss of $1.5 million in the three months ended December 31, 2017.Net income was  $1.2 million in the nine months ended December 31, 2016 compared to a net loss of $4.8 million in the nine months ended December 31, 2017. These fluctuations were primarily due to the changes in net revenues, gross profit and operating expenses discussed above.

Liquidity and Capital Resources

As of December 31, 2017, our principal sources of liquidity were cash, cash equivalents and short-term investmentsof $56.8 millioncompared to $49.9 million as of March 31, 2017.

Net cash used in operating activities was  $605,000 for the nine months ended December 31, 2017 compared to net cash provided by operating activities was $1.3 million for the nine months ended December 31, 2016. The primary uses of cash in the current nine month period were a net loss of $4.8 million, a decrease in deferred revenue of $1.3 million and a lesser decrease in accrued expenses and other liabilities.  The decrease in deferred revenue is primarily due to the recognition of $848,000 in additional revenue resulting from revisions to the distribution agreement with our largest distributor in the United States that eliminated ship from stock and debits and price protection rights that the distributor previously had. The primary sources of cash in the current nine month period were stock-based compensation of $1.5 million, a decrease in inventory of $1.3 million and a  provision for excess and obsolete inventories of $1.2 million,  depreciation and amortization expenses of $948,000 and a reduction in accounts receivable of $826,000.The primary sources of cash in the nine months ended December 31, 2016 were net income of $1.2 million, stock-based compensation of $1.4 million and depreciation and amortization expenses of $1.2 million. The primary use of cash in the nine months ended December 31, 2016 was an increase in inventory of $2.6 million. Our inventory balance increased in the prior period primarily due to the assembling of our LLDRAM products to support shipments in the subsequent six to nine months as we qualified a new assembly vendor. 

Net cash provided by investing activities was $4.5 million in the nine months ended December 31, 2017 compared to $3.3 million in the nine months ended December 31, 2016.  Investment activities in the nine months ended December 31, 2017 consisted primarily of the maturity of certificates of deposit of $10.5 million, partially offset by the purchase of agency bonds and certificates of deposit of $6.7 million and the purchase of property and equipment of $436,000. Investment activities in the nine months ended December 31, 2016 consisted primarily of the maturity of corporate notes, state and municipal obligations and certificates of deposit of $17.6 million, partially offset by the purchase of agency bonds and certificates of deposit of $14.1 million and the purchase of property and equipment for $194,000.

Net cash provided by financing activities in the nine months ended December 31, 2017 primarily consisted of the net proceeds from the sale of common stock pursuant to our employee stock plans of $2.9 million, partially offset the by release of an escrow deposit related to our acquisition of Mika Monu in November 2015 in the amount of $850,000.  Net cash used in financing activities in the nine months ended December 31, 2016 primarily consisted of the repurchase of $7.1 million of our common stock at an average purchase price of $4.33 per share, partially offset by the net proceeds from the sale of common stock pursuant to our employee stock plans.

The Company’s estimated annual effective income tax rate was approximately (13.7%) as of December 31, 2017.   We expect H.R. 1 to impact our net income, diluted earnings per share, and cash flows in future periods, due

23

primarily to the reduction in the federal corporate tax rate. We currently estimate that our blended consolidated effective income tax rate for full-year fiscal 2018 will approximate (3.0%) before discrete items. The blended statutory Federal tax rates for the year ending March 31, 2018 and 2019 will be 31.5% and 21%.  These tax-related estimates may differ from actual results, possibly materially, due to changes in interpretations of H.R. 1 and assumptions made by us, as well as guidance that may be issued and actions we may take as a result of H.R. 1.  See Note 5, Income Taxes, for further information.

We believe that our existing balances of cash, cash equivalents and short-term investments, and cash flow expected to be generated from our future operations will be sufficient to meet our cash needs for working capital and capital expenditures for at least the next 12 months, although we could be required, or could elect, to seek additional funding prior to that time. Our future capital requirements will depend on many factors, including revenue growth, if any, that we experience, the extent to which we utilize subcontractors, the levels of inventory and accounts receivable that we maintain, the timing and extent of spending to support our product development efforts and the expansion of our sales and marketing. Additional capital may also be required for the consummation of any acquisition of businesses, products or technologies that we may undertake. We cannot assure that additional equity or debt financing, if required, will be available on terms that are acceptable or at all.

Contractual Obligations

The following table describes our contractual obligations as of December 31, 2017:

	Payments due by period
	2018		2019 and 2020		2021 and 2022		After 2022		Total
Facilities and equipment leases	$	107,000	$	767,000	$	265,000	$	7,000	$	1,146,000
Wafer and test purchase obligations		698,000		779,000		—		—		1,477,000
	$	805,000	$	1,546,000	$	265,000	$	7,000	$	2,623,000

As of December 31, 2017, the current portion of our unrecognized tax benefits was $0, and the long-term portion was $823,000. We expect to make federal income tax payments in the next twelve months of approximately $5,000. As a result of  H.R 1, we recorded a liability for taxes payable of $68,000 at December 31, 2017 that will be paid over a period of up to eight years.

We expect expenditures of approximately $1,000,000 to be incurred in the next twelve months for construction on our headquarters building in Sunnyvale, CA.

In connection with the acquisition of MikaMonu on November 23, 2015, we are required to make contingent consideration payments to the former MikaMonu shareholders conditioned upon the retention of MikaMonu’s key employee and the achievement of certain product development milestones and revenue targets for products based on the MikaMonu technology. As of December 31, 2017, the accrual for potential contingent consideration was $5.9 million.

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2017.

Please refer to Note 5 to our condensed consolidated financial statements appearing under Part I, Item 1 for a discussion regarding how H.R. 1 may impact the Company’s critical accounting policies and estimates.

Off-Balance Sheet Arrangements

At December 31, 2017, we did not have any off-balance sheet arrangements or relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, established for the purpose of facilitating off-balance sheet arrangements or other contractually

24

narrow or limited purposes. Accordingly, we are not exposed to the type of financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

Recent Accounting Pronouncements

Please refer to Note 1 to our condensed consolidated financial statements appearing under Part I, Item 1 for a discussion of recent accounting pronouncements that may impact the Company.

Item 3.Quantitative and Qualitative Disclosure About Market Risk

Foreign Currency Exchange Risk. Our revenues and expenses, except those expenses related to our operations in Taiwan and in Israel, including subcontractor manufacturing expenses, are denominated in U.S. dollars. As a result, we have relatively little exposure for currency exchange risks, and foreign exchange gains and losses have been minimal to date. We do not currently enter into forward exchange contracts to hedge exposure denominated in foreign currencies or any other derivative financial instruments for trading or speculative purposes. In the future, if we feel our foreign currency exposure has increased, we may consider entering into hedging transactions to help mitigate that risk.

Interest Rate Sensitivity.  We had cash, cash equivalents, short-term investments and long-term investments totaling $65.0 million at December 31, 2017. These amounts were invested primarily in money market funds, state and municipal obligations, certificates of deposit, government agency bonds and foreign government obligations. The cash, cash equivalents and short-term marketable securities are held for working capital purposes. We do not enter into investments for trading or speculative purposes. Due to the short-term nature of these investments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. We believe a hypothetical 100 basis point increase or decrease in interest rates would not materially affect the fair value of our interest-sensitive financial instruments.  Declines in interest rates, however, will reduce future investment income.

Item 4.Controls and Procedures

Management’s Evaluation of Disclosure Controls and Procedures 

Based on their evaluation 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) as of December 31, 2017, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report for the purpose of ensuring that the information required to be disclosed by us in this report is made known to them by others on a timely basis, and that the information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, in order to allow timely decisions regarding required disclosure, and that such information is recorded, processed, summarized, and reported by us within the time periods specified in the SEC's rules and instructions for Form 10-Q.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 1A.Risk Factors

Our future performance is subject to a variety of risks.  If any of the following risks actually occur, our business, financial condition and results of operations could suffer and the trading price of our common stock could decline.  Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business operations. You should also refer to other information contained in this report, including our condensed consolidated financial statements and related notes.  The risk factors described below do not contain any

25

material changes from those previously disclosed in Item 1A of our Annual Report on Form 10-K for the fiscal year ended March 31, 2017.

Unpredictable fluctuations in our operating results could cause our stock price to decline.

Our quarterly and annual revenues, expenses and operating results have varied significantly and are likely to vary in the future. For example, in the eleven fiscal quarters ended December 31, 2017, we recorded net revenues of as much as $14.0 million and as little as $9.6 million and quarterly operating income of as much as$389,000 and, in eight quarters, operating losses, including our operating loss of $1.8 million in the quarter ended September 30, 2017. We therefore believe that period-to-period comparisons of our operating results are not a good indication of our future performance, and you should not rely on them to predict our future performance or the future performance of our stock price. In future periods, we may not have any revenue growth, or our revenues could decline. Furthermore, if our operating expenses exceed our expectations, our financial performance could be adversely affected. Factors that may affect periodic operating results in the future include:

· changes in our customers' inventory management practices;

· unpredictability of the timing and size of customer orders, since most of our customers purchase our products on a purchase order basis rather than pursuant to a long-term contract;

· our ability to anticipate and conform to new industry standards;

· fluctuations in availability and costs associated with materials needed to satisfy customer requirements;

· manufacturing defects, which could cause us to incur significant warranty, support and repair costs, lose potential sales, harm our relationships with customers and result in write-downs;

· changes in our product pricing policies, including those made in response to new product announcements and pricing changes of our competitors; and

· our ability to address technology issues as they arise, improve our products' functionality and expand our product offerings.

Our expenses are, to a large extent, fixed, and we expect that these expenses will increase in the future. We will not be able to adjust our spending quickly if our revenues fall short of our expectations. If this were to occur, our operating results would be harmed. If our operating results in future quarters fall below the expectations of market analysts and investors, the price of our common stock could fall.

Our two largest OEM customers account for a significant percentage of our net revenues. If either of these customers, or any of our other major customers, reduces the amount they purchase or stop purchasing our products, our operating results will suffer.

Nokia (Alcatel-Lucent), currently our largest customer, purchases our products directly from us and through contract manufacturers and distributors.  Purchases by Nokia (Alcatel-Lucent) represented approximately 36%, 41%, 32% and 25% of our net revenues in the nine months ended December 31, 2017 and in fiscal 2017,  2016 and 2015, respectively. Cisco Systems, historically our largest OEM customer, purchases our products through its consignment warehouses and contract manufacturers and directly from us. Purchases by Cisco Systems represented approximately 6%,9%, 9% and 13% of our net revenues in the nine months ended December 31, 2017 and in fiscal 2017,  2016 and 2015, respectively.We expect that our operating results in any given period will continue to depend significantly on orders from our key OEM customers, particularly Nokia (Alcatel-Lucent) and Cisco Systems, and our future success is dependent to a large degree on the business success of these OEMs over which we have no control. We do not have long-term contracts with Nokia (Alcatel-Lucent), Cisco Systems or any of our other major OEM customers, distributors or contract manufacturers that obligate them to purchase our products.  We expect that future direct and indirect sales to Nokia (Alcatel-Lucent), Cisco Systems and our other key OEM customers will continue to fluctuate significantly on a quarterly basis and that such fluctuations may substantially affect our

26

operating results in future periods. If we fail to continue to sell to our key OEM customers, distributors or contract manufacturers in sufficient quantities, our business could be harmed.

We have incurred significant losses in prior periods and may incur losses in the future.

We have incurred significant losses in prior periods. We incurred losses of $115,000, $2.2 million and $5.0 million during fiscal 2017, 2016 and 2015, respectively. Our operating expenses over the past several years included substantial expenses related to legal proceedings which resulted in operating losses. Although these proceedings are substantially concluded, there can be no assurance that our Very Fast SRAMs will continue to receive broad market acceptance, that our new product development initiatives will be successful or that we will be able to achieve sustained revenue growth or profitability.

We depend upon the sale of our Very Fast SRAMs for most of our revenues, and a downturn in demand for these products could significantly reduce our revenues and harm our business.

We derive most of our revenues from the sale of Very Fast SRAMs, and we expect that sales of these products will represent the substantial majority of our revenues for the foreseeable future. Our business depends in large part upon continued demand for our products in the markets we currently serve, and adoption of our products in new markets. Market adoption will be dependent upon our ability to increase customer awareness of the benefits of our products and to prove their high-performance and cost-effectiveness. We may not be able to sustain or increase our revenues from sales of our products, particularly if the networking and telecommunications markets were to experience another significant downturn in the future. Any decrease in revenues from sales of our products could harm our business more than it would if we offered a more diversified line of products.

If we do not successfully develop new products to respond to rapid market changes due to changing technology and evolving industry standards, particularly in the networking and telecommunications markets, our business will be harmed.

If we fail to offer technologically advanced products and respond to technological advances and emerging standards, we may not generate sufficient revenues to offset our development costs and other expenses, which will hurt our business. The development of new or enhanced products is a complex and uncertain process that requires the accurate anticipation of technological and market trends. In particular, the networking and telecommunications markets are rapidly evolving and new standards are emerging. We are vulnerable to advances in technology by competitors, including new SRAM architectures, new forms of DRAM and the emergence of new memory technologies that could enable the development of products that feature higher performance or lower cost. We may experience development, marketing and other technological difficulties that may delay or limit our ability to respond to technological changes, evolving industry standards, competitive developments or end-user requirements. For example, because we have limited experience developing integrated circuits, or IC, products other than Very Fast SRAMs and LLDRAMs, our efforts to introduce new products may not be successful and our business may suffer. Other challenges that we face include:

· our products may become obsolete upon the introduction of alternative technologies;

· we may incur substantial costs if we need to modify our products to respond to these alternative technologies;

· we may not have sufficient resources to develop or acquire new technologies or to introduce new products capable of competing with future technologies;

· new products that we develop may not successfully integrate with our end-users' products into which they are incorporated;

· we may be unable to develop new products that incorporate emerging industry standards;

27

· we may be unable to develop or acquire the rights to use the intellectual property necessary to implement new technologies; and

· when introducing new or enhanced products, we may be unable to manage effectively the transition from older products.

Our future success is substantially dependent on the successful development of new in-place associative computing products which entails significant risks. 

Since our acquisition of MikaMonu in November 2015, our principal strategic objective has been the development of a new category of in-place associative computing products based on patented technology that we acquired in the acquisition.  We have devoted, and are continuing to devote, substantial efforts and resources to this development effort.  This ongoing project involves the commercialization of new, cutting-edge technology, will require a substantial effort over a year or more and will be subject to significant risks.  In addition to the typical risks associated with the development of technologically advanced products (as outlined in the previous paragraph), this project will be subject to enhanced risks of technological problems related to the development of an entirely new category of products, substantial risks of delays or unanticipated costs that may be encountered and risks associated with the establishment of entirely new markets and customer relationships.  Our inability to successfully conclude this major development effort and establish a market for the products we hope to develop would have a material adverse effect on our future financial and business success, including our prospects for increased revenues.  Additionally, if we are unable to meet the expectations of market analysts and investors with respect to this major development effort, then the price of our common stock could fall.

We are subject to the highly cyclical nature of the networking and telecommunications markets.

Our products are incorporated into routers, switches, wireless local area network infrastructure equipment, wireless base stations and network access equipment used in the highly cyclical networking and telecommunications markets. We expect that the networking and telecommunications markets will continue to be highly cyclical, characterized by periods of rapid growth and contraction. Our business and our operating results are likely to fluctuate, perhaps quite severely, as a result of this cyclicality.

The market for Very Fast SRAMs is highly competitive.

The market for Very Fast SRAMs, which are used primarily in networking and telecommunications equipment, is characterized by price erosion, rapid technological change, cyclical market patterns and intense foreign and domestic competition. Several of our competitors offer a broad array of memory products and have greater financial, technical, marketing, distribution and other resources than we have. Some of our competitors maintain their own semiconductor fabrication facilities, which may provide them with capacity, cost and technical advantages over us. We cannot assure you that we will be able to compete successfully against any of these competitors. Our ability to compete successfully in this market depends on factors both within and outside of our control, including:

· real or perceived imbalances in supply and demand of Very Fast SRAMs;

· the rate at which OEMs incorporate our products into their systems;

· the success of our customers' products;

· our ability to develop and market new products; and

· the supply and cost of wafers.

In addition, we are vulnerable to advances in technology by competitors, including new SRAM architectures and new forms of DRAM, or the emergence of new memory technologies that could enable the development of products that feature higher performance, lower cost or lower power capabilities. Additionally, the trend toward

28

incorporating SRAM into other chips in the networking and telecommunications markets has the potential to reduce future demand for Very Fast SRAM products. There can be no assurance that we will be able to compete successfully in the future. Our failure to compete successfully in these or other areas could harm our business.

The average selling prices of our products are expected to decline, and if we are unable to offset these declines, our operating results will suffer.

Historically, the average unit selling prices of our products have declined substantially over the lives of the products, and we expect this trend to continue. A reduction in overall average selling prices of our products could result in reduced revenues and lower gross margins. Our ability to increase our net revenues and maintain our gross margins despite a decline in the average selling prices of our products will depend on a variety of factors, including our ability to introduce lower cost versions of our existing products, increase unit sales volumes of these products, and introduce new products with higher prices and greater margins. If we fail to accomplish any of these objectives, our business will suffer. To reduce our costs, we may be required to implement design changes that lower our manufacturing costs, negotiate reduced purchase prices from our independent foundries and our independent assembly and test vendors, and successfully manage our manufacturing and subcontractor relationships. Because we do not operate our own wafer foundry or assembly facilities, we may not be able to reduce our costs as rapidly as companies that operate their own foundries or facilities.

Global economic and market conditions may adversely affect our business, financial condition and results of operations.

We sell our products to end customers both in the United States and internationally.  We also rely heavily on our suppliers in Asia.  We are therefore susceptible to adverse domestic and international economic and market conditions.  In recent years, turmoil in global financial markets and economic conditions has impacted credit availability, consumer spending and capital expenditures, including expenditures for networking and telecommunications equipment.  Weakness in global networking and telecommunications markets, particularly in Asia, has continued to adversely impact our revenues in recent quarters.  Slowness in economic growth, domestically and in our key markets, uncertainty regarding macroeconomic trends, and volatility in financial markets may continue to adversely affect our business, financial condition and results of operations over coming quarters.

We are dependent on a number of single source suppliers, and if we fail to obtain adequate supplies, our business will be harmed and our prospects for growth will be curtailed.

We currently purchase several key components used in the manufacture of our products from single sources and are dependent upon supply from these sources to meet our needs. If any of these suppliers cannot provide components on a timely basis, at the same price or at all, our ability to manufacture our products will be constrained and our business will suffer. Most significantly, we obtain wafers for our Very Fast SRAM products from a single foundry, TSMC, and most of them are packaged at ASE. Wafers for our LLDRAM products are obtained exclusively from Powerchip.  If we are unable to obtain an adequate supply of wafers from TSMC or Powerchip or find alternative sources in a timely manner, we will be unable to fulfill our customer orders and our operating results will be harmed. We do not have supply agreements with TSMC, Powerchip, ASE or any of our other independent assembly and test suppliers, and instead obtain manufacturing services and products from these suppliers on a purchase-order basis. Our suppliers, including TSMC and Powerchip, have no obligation to supply products or services to us for any specific product, in any specific quantity, at any specific price or for any specific time period. As a result, the loss or failure to perform by any of these suppliers could adversely affect our business and operating results.

Should any of our single source suppliers experience manufacturing failures or yield shortfalls, be disrupted by natural disaster or political instability, choose to prioritize capacity or inventory for other uses or reduce or eliminate deliveries to us for any other reason, we likely will not be able to enforce fulfillment of any delivery commitments and we would have to identify and qualify acceptable replacements from alternative sources of supply. In particular, if TSMC is unable to supply us with sufficient quantities of wafers to meet all of our requirements, we would have to allocate our products among our customers, which would constrain our growth and might cause some of them to seek alternative sources of supply. Since the manufacturing of wafers and other components is extremely

29

complex, the process of qualifying new foundries and suppliers is a lengthy process and there is no assurance that we would be able to find and qualify another supplier without materially adversely affecting our business, financial condition and results of operations.

Because we outsource our wafer manufacturing and independent wafer foundry capacity is limited, we may be required to enter into costly long-term supply arrangements to secure foundry capacity.

We do not have long-term supply agreements with TSMC or Powerchip, but instead obtain our wafers on a purchase order basis. In order to secure future wafer supply from TSMC or Powerchip or from other independent foundries, we may be required to enter into various arrangements with them, which could include:

· contracts that commit us to purchase specified quantities of wafers over extended periods;

· investments in and joint ventures with the foundries; or

· non-refundable deposits with or prepayments or loans to foundries in exchange for capacity commitments.

We may not be able to make any of these arrangements in a timely fashion or at all, and these arrangements, if any, may not be on terms favorable to us. Moreover, even if we are able to secure independent foundry capacity, we may be obligated to use all of that capacity or incur penalties. These penalties may be expensive and could harm our financial results.

If we are unable to offset increased wafer fabrication costs by increasing the average selling prices of our products, our gross margins will suffer.

If there is a significant upturn in the networking and telecommunications markets that results in increased demand for our products and competing products, the available supply of wafers may be limited. As a result, we could be required to obtain additional manufacturing capacity in order to meet increased demand. Securing additional manufacturing capacity may cause our wafer fabrication costs to increase. If we are unable to offset these increased costs by increasing the average selling prices of our products, our gross margins will decline.

We rely heavily on distributors and our success depends on our ability to develop and manage our indirect distribution channels.

A significant percentage of our sales are made to distributors and to contract manufacturers who incorporate our products into end products for OEMs.For example, in the nine months ended December 31, 2017 and in fiscal 2017,  2016 and 2015, our distributor Avnet Logistics accounted for 34.7%, 25.5%, 28.2% and 35.2%, respectively, of our net revenues. Avnet Logistics and our other existing distributors may choose to devote greater resources to marketing and supporting the products of other companies. Since we sell through multiple channels and distribution networks, we may have to resolve potential conflicts between these channels. For example, these conflicts may result from the different discount levels offered by multiple channel distributors to their customers or, potentially, from our direct sales force targeting the same equipment manufacturer accounts as our indirect channel distributors. These conflicts may harm our business or reputation.

We may be unable to accurately predict future sales through our distributors, which could harm our ability to efficiently manage our resources to match market demand.

Our financial results, quarterly product sales, trends and comparisons are affected by fluctuations in the buying patterns of the OEMs that purchase our products from our distributors. While we attempt to assist our distributors in maintaining targeted stocking levels of our products, we may not consistently be accurate or successful. This process involves the exercise of judgment and use of assumptions as to future uncertainties, including end user demand. Inventory levels of our products held by our distributors may exceed or fall below the levels we consider desirable on a going-forward basis. This could result in distributors returning unsold inventory to us, or in us not having sufficient inventory to meet the demand for our products. If we are not able to accurately

30

predict sales through our distributors or effectively manage our relationships with our distributors, our business and financial results will suffer.

A small number of customers generally account for a significant portion of our accounts receivable in any period, and if any one of them fails to pay us, our financial position and operating results will suffer.

At December 31, 2017,  four customers accounted for 38%,  18%,  14% and 14% of our accounts receivable, respectively. If any of these customers do not pay us, our financial position and operating results will be harmed. Generally, we do not require collateral from our customers.

We have previously disclosed a material weakness in our internal control over financial reporting relating to the evaluation and calculation of our inventory reserve which management believes has been fully remediated. Should we have inadequately remediated this material weakness or should we otherwise fail to maintain effective internal control over financial reporting and disclosure controls and processes, our ability to report our financial condition and results of operations accurately and on a timely basis could be adversely affected.

In connection with the completion of the quarter-end closing and review procedures for the quarter ended December 31, 2013, certain errors were identified in the evaluation and calculation of our inventory write-down for the quarter and nine month period then ended that were the result of a material weakness in our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

During these closing and review procedures, our management determined that we had not designed and maintained effective controls over the review of supporting information to confirm the completeness and accuracy of our calculations for the write-down of excess or obsolete inventory, thereby affecting the valuation of our inventory as of December 31, 2013.  While this control deficiency did not result in any material misstatement of our historical financial statements, it did result in adjustments identified by our auditors as part of their quarterly review process, and require corrections after our initial estimate of excess and obsolete inventory write-downs for the three month period ended December 31, 2013.

A material weakness in our internal control over financial reporting could adversely impact our ability to provide timely and accurate financial information.  Following the identification of the error in our financial statements and the material weakness that gave rise to the error, our management implemented a remediation plan which it believes fully remediated the material weakness.  Should our remediation efforts prove to have been inadequate or should we otherwise fail to maintain effective internal control over financial reporting and disclosure controls and procedures, we could be unable to meet our reporting obligations accurately and on a timely basis. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could adversely affect the trading price of our common stock.

Our acquisition of companies or technologies could prove difficult to integrate, disrupt our business, dilute stockholder value and adversely affect our operating results.

In November 2015, we acquired all of the outstanding capital stock of privately held MikaMonu Group Ltd., a development-stage, Israel-based company that specializes in in-place associative computing for markets including big data, computer vision and cyber security. We also acquired substantially all of the assets related to the SRAM memory device product line of Sony Corporation in 2009. We intend to supplement our internal development activities by seeking opportunities to make additional acquisitions or investments in companies, assets or technologies that we believe are complementary or strategic. Other than the MikaMonu and Sony acquisitions, we have not made any such acquisitions or investments, and therefore our experience as an organization in making such acquisitions and investments is limited. In connection with the MikaMonu acquisition, we are subject to risks related to potential problems, delays or anticipated costs that may be encountered in the development of products based on the MikaMonu technology and the establishment of new markets and customer relationships for the potential new

31

products.  In addition, in connection with the MikaMonu acquisition and any future acquisitions or investments we may make, we face numerous other risks, including:

· difficulties in integrating operations, technologies, products and personnel;

· diversion of financial and managerial resources from existing operations;

· risk of overpaying for or misjudging the strategic fit of an acquired company, asset or technology;

· problems or liabilities stemming from defects of an acquired product or intellectual property litigation that may result from offering the acquired product in our markets;

· challenges in retaining key employees to maximize the value of the acquisition or investment;

· inability to generate sufficient return on investment;

· incurrence of significant one-time write-offs; and

· delays in customer purchases due to uncertainty.

If we proceed with additional acquisitions or investments, we may be required to use a considerable amount of our cash, or to finance the transaction through debt or equity securities offerings, which may decrease our financial liquidity or dilute our stockholders and affect the market price of our stock. As a result, if we fail to properly evaluate and execute acquisitions or investments, our business and prospects may be harmed.

Claims that we infringe third party intellectual property rights could seriously harm our business and require us to incur significant costs.

In recent years, there has been significant litigation in the semiconductor industry involving patents and other intellectual property rights.  We have recently been involved in protracted patent infringement litigation, and  we could become subject to additional claims or litigation in the future as a result of allegations that we infringe others' intellectual property rights or that our use of intellectual property otherwise violates the law. Claims that our products infringe the proprietary rights of others would force us to defend ourselves and possibly our customers, distributors or manufacturers against the alleged infringement. Any such litigation regarding intellectual property could result in substantial costs and diversion of resources and could have a material adverse effect on our business, financial condition and results of operations. Similarly, changing our products or processes to avoid infringing the rights of others may be costly or impractical. If any claims received in the future were to be upheld, the consequences to us could require us to:

· stop selling our products that incorporate the challenged intellectual property;

· obtain a license to sell or use the relevant technology, which license may not be available on reasonable terms or at all;

· pay damages; or

· redesign those products that use the disputed technology.

Although patent disputes in the semiconductor industry have often been settled through cross-licensing arrangements, we may not be able in any or every instance to settle an alleged patent infringement claim through a cross-licensing arrangement in part because we have a more limited patent portfolio than many of our competitors. If a successful claim is made against us or any of our customers and a license is not made available to us on commercially reasonable terms or we are required to pay substantial damages or awards, our business, financial condition and results of operations would be materially adversely affected.

32

Our business will suffer if we are unable to protect our intellectual property.

Our success and ability to compete depends in large part upon protecting our proprietary technology. We rely on a combination of patent, trade secret, copyright and trademark laws and non-disclosure and other contractual agreements to protect our proprietary rights. These agreements and measures may not be sufficient to protect our technology from third-party infringement. Monitoring unauthorized use of our intellectual property is difficult and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. Our attempts to enforce our intellectual property rights could be time consuming and costly. We were recently involved in litigation to enforce our intellectual property rights and to protect our trade secrets. Additional litigation of this type may be necessary in the future. Any such litigation could result in substantial costs and diversion of resources. If competitors are able to use our technology without our approval or compensation, our ability to compete effectively could be harmed.

System security risks, data protection, cyber-attacks and systems integration issues could disrupt our internal operations or the operations of our business partners, and any such disruption could harm our reputation or cause a reduction in our expected revenue, increase our expenses, negatively impact our results of operation or otherwise adversely affect our stock price.

Security breaches, computer malware and cyber-attacks have become more prevalent and sophisticated in recent years. Experienced computer programmers and hackers may be able to penetrate our network security or the network security of our business partners, and misappropriate or compromise our confidential and proprietary information, create system disruptions or cause shutdowns. The costs to us to eliminate or alleviate cyber or other security problems, bugs, viruses, worms, malicious software programs and security vulnerabilities could be significant, and our efforts to address these problems may not be successful and could result in interruptions and delays that may impede our sales, manufacturing, distribution or other critical functions.

We manage and store various proprietary information and sensitive or confidential data relating to our business on the cloud. Breaches of our security measures or the accidental loss, inadvertent disclosure or unapproved dissemination of proprietary information or confidential data about us, including the potential loss or disclosure of such information or data as a result of fraud, trickery or other forms of deception, could expose us to a risk of loss or misuse of this information, result in litigation and potential liability for us, damage our reputation or otherwise harm our business. In addition, the cost and operational consequences of implementing further data protection measures could be significant.

Portions of our IT infrastructure also may experience interruptions, delays or cessations of service or produce errors in connection with systems integration or migration work that takes place from time to time. We may not be successful in implementing new systems and transitioning data, which could cause business disruptions and be more expensive, time consuming, disruptive and resource-intensive than originally anticipated. Such disruptions could adversely impact our ability to fulfill orders and interrupt other processes and could adversely affect our financial results, stock price and reputation.

We may experience difficulties in transitioning to smaller geometry process technologies and other more advanced manufacturing process technologies, which may result in reduced manufacturing yields, delays in product deliveries and increased expenses.

In order to remain competitive, we expect to continue to transition the manufacture of our products to smaller geometry process technologies. This transition will require us to migrate to new manufacturing processes for our products and redesign certain products. The manufacture and design of our products is complex, and we may experience difficulty in transitioning to smaller geometry process technologies or new manufacturing processes. These difficulties could result in reduced manufacturing yields, delays in product deliveries and increased expenses. We are dependent on our relationships with TSMC and Powerchip to transition successfully to smaller geometry process technologies and to more advanced manufacturing processes. We cannot assure you that TSMC or Powerchip will be able to effectively manage the transition or that we will be able to maintain our relationship with them. If we or TSMC or Powerchip experience significant delays in this transition or fail to implement these transitions, our business, financial condition and results of operations could be materially and adversely affected.

33

Manufacturing process technologies are subject to rapid change and require significant expenditures for research and development.

We continuously evaluate the benefits of migrating to smaller geometry process technologies in order to improve performance and reduce costs. Historically, these migrations to new manufacturing processes have resulted in significant initial design and development costs associated with pre-production mask sets for the manufacture of new products with smaller geometry process technologies.  For example, in fiscal 2014, we incurred $809,000 and $648,000, respectively, in research and development expense associated with pre-production mask sets which were not later used in production as part of the transition to our new 40 nanometer SRAM process technology and 63 nanometer DRAM process technology.  We will incur similar expenses in the future as we continue to transition our products to smaller geometry processes. The costs inherent in the transition to new manufacturing process technologies will adversely affect our operating results and our gross margin.

Our products are complex to design and manufacture and could contain defects, which could reduce revenues or result in claims against us.

We develop complex products. Despite testing by us and our OEM customers, design or manufacturing errors may be found in existing or new products. These defects could result in a delay in recognition or loss of revenues, loss of market share or failure to achieve market acceptance. These defects may also cause us to incur significant warranty, support and repair costs, divert the attention of our engineering personnel from our product development efforts, result in a loss of market acceptance of our products and harm our relationships with our OEM customers. Our OEM customers could also seek and obtain damages from us for their losses. A product liability claim brought against us, even if unsuccessful, would likely be time consuming and costly to defend.

Defects in wafers and other components used in our products and arising from the manufacturing of these products may not be fully recoverable from TSMC or our other suppliers. For example, in the quarter ended December 31, 2005, we incurred a charge of approximately $900,000 related to the write-off of inventory resulting from an error in the assembly process at one of our suppliers. This write-off adversely affected our operating results for fiscal 2006.

Demand for our products may decrease if our OEM customers experience difficulty manufacturing, marketing or selling their products.

Our products are used as components in our OEM customers' products, including routers, switches and other networking and telecommunications products. Accordingly, demand for our products is subject to factors affecting the ability of our OEM customers to successfully introduce and market their products, including:

· capital spending by telecommunication and network service providers and other end-users who purchase our OEM customers' products;

· the competition our OEM customers face, particularly in the networking and telecommunications industries;

· the technical, manufacturing, sales and marketing and management capabilities of our OEM customers;

· the financial and other resources of our OEM customers; and

· the inability of our OEM customers to sell their products if they infringe third-party intellectual property rights.

As a result, if OEM customers reduce their purchases of our products, our business will suffer.

34

Our products have lengthy sales cycles that make it difficult to plan our expenses and forecast results.

Our products are generally incorporated in our OEM customers' products at the design stage. However, their decisions to use our products often require significant expenditures by us without any assurance of success, and often precede volume sales, if any, by a year or more. If an OEM customer decides at the design stage not to incorporate our products into their products, we will not have another opportunity for a design win with respect to that customer's product for many months or years, if at all. Our sales cycle can take up to 24 months to complete, and because of this lengthy sales cycle, we may experience a delay between increasing expenses for research and development and our sales and marketing efforts and the generation of volume production revenues, if any, from these expenditures. Moreover, the value of any design win will largely depend on the commercial success of our OEM customers' products. There can be no assurance that we will continue to achieve design wins or that any design win will result in future revenues.

Any significant order cancellations or order deferrals could adversely affect our operating results.

We typically sell products pursuant to purchase orders that customers can generally cancel or defer on short notice without incurring a significant penalty. Any significant cancellations or deferrals in the future could materially and adversely affect our business, financial condition and results of operations. Cancellations or deferrals could cause us to hold excess inventory, which could reduce our profit margins, increase product obsolescence and restrict our ability to fund our operations. We generally recognize revenue upon shipment of products to a customer. If a customer refuses to accept shipped products or does not pay for these products, we could miss future revenue projections or incur significant charges against our income, which could materially and adversely affect our operating results.

If our business grows, such growth may place a significant strain on our management and operations and, as a result, our business may suffer.

We are endeavoring to expand our business, and any growth that we are successful in achieving could place a significant strain on our management systems, infrastructure and other resources. To manage such growth of our operations and resulting increases in the number of our personnel, we will need to invest the necessary capital to continue to improve our operational, financial and management controls and our reporting systems and procedures. Our controls, systems and procedures may prove to be inadequate should we experience significant growth. In addition, we may not have sufficient administrative staff to support our operations. For example, we currently have only five employees in our finance department in the United States, including our Chief Financial Officer. Furthermore, our officers have limited experience in managing large or rapidly growing businesses. If our management fails to respond effectively to changes in our business, our business may suffer.

We are substantially dependent on the continued services and performance of our senior management and other key personnel.

Our future success is substantially dependent on the continued services and continuing contributions of our senior management who must work together effectively in order to design our products, expand our business, increase our revenues and improve our operating results. Members of our senior management team have long-standing and important relationships with our key customers and suppliers.  The loss of services of Lee-Lean Shu, our President and Chief Executive Officer, Robert Yau, our Vice President of Engineering, Dr. Avidan Akerib our Vice President of Associative Computing, any other executive officer or other key employee could significantly delay or prevent the achievement of our development and strategic objectives. We do not have employment contracts with, nor maintain key person insurance on, any of our executive officers or other key employees.

If we are unable to recruit or retain qualified personnel, our business and product development efforts could be harmed.

We must continue to identify, recruit, hire, train, retain and motivate highly skilled technical, managerial, sales and marketing and administrative personnel. Competition for these individuals is intense, and we may not be able to successfully recruit, assimilate or retain sufficiently qualified personnel. We may encounter difficulties in recruiting and retaining a sufficient number of qualified engineers, which could harm our ability to develop new

35

products and adversely impact our relationships with existing and future end-users at a critical stage of development. The failure to recruit and retain necessary technical, managerial, sales, marketing and administrative personnel could harm our business and our ability to obtain new OEM customers and develop new products.

Our international business exposes us to additional risks.

Products shipped to destinations outside of the United States accounted for 49.7%, 59.1%, 60.3% and 66.2% of our net revenues in the nine months ended December 31, 2017 and in fiscal 2017,  2016 and 2015, respectively. Moreover, a substantial portion of our products is manufactured and tested in Taiwan, and we are now conducting business operations in Israel as a result of our acquisition of MikaMonu. We intend to continue expanding our international business in the future. Conducting business outside of the United States subjects us to additional risks and challenges, including:

· heightened price sensitivity from customers in emerging markets;

· compliance with a wide variety of foreign laws and regulations and unexpected changes in these laws and regulations;

· legal uncertainties regarding taxes, tariffs, quotas, export controls, competition, export licenses and other trade barriers;

· potential political and economic instability in, or foreign conflicts that involve or affect, the countries in which we, our customers and our suppliers are located;

· difficulties in collecting accounts receivable and longer accounts receivable payment cycles;

· difficulties and costs of staffing and managing personnel, distributors and representatives across different geographic areas and cultures, including assuring compliance with the U. S. Foreign Corrupt Practices Act and other U. S. and foreign anti-corruption laws;

· limited protection for intellectual property rights in some countries; and

· fluctuations in freight rates and transportation disruptions.

Moreover, our reporting currency is the U.S. dollar. However, a portion of our cost of revenues and our operating expenses is denominated in currencies other than the U.S. dollar, primarily the New Taiwanese dollar. As a result, appreciation or depreciation of other currencies in relation to the U.S. dollar could result in transaction gains or losses that could impact our operating results. We do not currently engage in currency hedging activities to reduce the risk of financial exposure from fluctuations in foreign exchange rates.

U.S. federal income tax reform could adversely affect us.

On December 22, 2017, the “Tax Cuts and Jobs Act” (“H.R. 1”) was signed into law, significantly impacting several sections of the Internal Revenue Code. This new law includes significant changes to the U.S. corporate income tax system, including a permanent reduction in the corporate income tax rate from 35% to 21%, limitations on the deductibility of interest expense and executive compensation and the transition of U.S. international taxation from a worldwide tax system to a territorial tax system.  We are continuing to examine the impact that H.R. 1 may have on our business.  We have remeasured all deferred tax assets and liabilities as of December 22, 2017, based on the provisions of H.R. 1. This new legislation resulted in an estimated tax provision of $639,000 in the quarter ended December 31, 2017 related to the transition tax associated with deemed repatriation of foreign earnings. In addition, as a result of provisions in the new legislation related to indefinite lived net operating loss carryovers and the refundability of minimum tax credit carryovers, we recorded a deferred tax benefit related to a valuation allowance release of $99,000 in the quarter ended December 31, 2017. Finally,  we recorded a liability for taxes payable of $68,000 at December 31, 2017 that will be paid over a period of up to eight years. 

36

This estimated tax provision and the impact of H.R. 1 is based on our management’s current knowledge and assumptions and recognized impacts could be materially different from estimated provisions based upon a number of additional considerations, including but not limited to the issuance of the final regulations, our ongoing analysis of the new law and our actual earnings for the fiscal year ending March 31, 2018.

TSMC and Powerchip, as well as our other independent suppliers and many of our OEM customers have operations in the Pacific Rim, an area subject to significant earthquake risk and adverse consequences related to the potential outbreak of contagious diseases such as the H1N1 Flu.

The foundries that manufacture our Fast SRAM and LLDRAM products, TSMC and Powerchip, and all of the principal independent suppliers that assemble and test our products are located in Taiwan. Many of our customers are also located in the Pacific Rim. The risk of an earthquake in these Pacific Rim locations is significant. The occurrence of an earthquake or other natural disaster near the fabrication facilities of TSMC or our other independent suppliers could result in damage, power outages and other disruptions that impair their production and assembly capacity. Any disruption resulting from such events could cause significant delays in the production or shipment of our products until we are able to shift our manufacturing, assembling, packaging or production testing from the affected contractor to another third-party vendor. In such an event, we may not be able to obtain alternate foundry capacity on favorable terms, or at all.

The outbreak of SARS in 2003 curtailed travel to and from certain countries, primarily in the Asia-Pacific region, and limited travel within those countries. If there were to be another outbreak of a contagious disease, such as SARS or the H1N1 Flu, that significantly affected the Asia-Pacific region, the operations of our key suppliers could be disrupted. In addition, our business could be harmed if such an outbreak resulted in travel being restricted, as it was during parts of 2003, or if it adversely affected the operations of our suppliers or our OEM customers or the demand for our products or our OEM customers' products.

Changes in Taiwan's political, social and economic environment may affect our business performance.

Because much of the manufacturing and testing of our products is conducted in Taiwan, our business performance may be affected by changes in Taiwan's political, social and economic environment. For example, any political instability resulting from the relationship among the United States, Taiwan and the People's Republic of China could damage our business. Moreover, the role of the Taiwanese government in the Taiwanese economy is significant. Taiwanese policies toward economic liberalization, and laws and policies affecting technology companies, foreign investment, currency exchange rates, taxes and other matters could change, resulting in greater restrictions on our ability and our suppliers' ability to do business and operate facilities in Taiwan. If any of these changes were to occur, our business could be harmed and our stock price could decline.

We may need to raise additional capital in the future, which may not be available on favorable terms or at all, and which may cause dilution to existing stockholders.

We may need to seek additional funding in the future. We do not know if we will be able to obtain additional financing on favorable terms, if at all. If we cannot raise funds on acceptable terms, if and when needed, we may not be able to develop or enhance our products, take advantage of future opportunities or respond to competitive pressures or unanticipated requirements, and we may be required to reduce operating costs, which could seriously harm our business. In addition, if we issue equity securities, our stockholders may experience dilution or the new equity securities may have rights, preferences or privileges senior to those of our common stock.

Some of our products are incorporated into advanced military electronics, and changes in international geopolitical circumstances and domestic budget considerations may hurt our business.

Some of our products are incorporated into advanced military electronics such as radar and guidance systems. Military expenditures and appropriations for such purchases rose significantly in recent years. However, as the current conflict in Afghanistan winds down, demand for our products for use in military applications may decrease, and our operating results could suffer. Domestic budget considerations may also adversely affect our

37

operating results. For example, if governmental appropriations for military purchases of electronic devices that include our products are reduced, our revenues will likely decline.

Our operations involve the use of hazardous and toxic materials, and we must comply with environmental laws and regulations, which can be expensive, and may affect our business and operating results.

We are subject to federal, state and local regulations relating to the use, handling, storage, disposal and human exposure to hazardous and toxic materials. If we were to violate or become liable under environmental laws in the future as a result of our inability to obtain permits, human error, accident, equipment failure or other causes, we could be subject to fines, costs, or civil or criminal sanctions, face property damage or personal injury claims or be required to incur substantial investigation or remediation costs, which could be material, or experience disruptions in our operations, any of which could have a material adverse effect on our business. In addition, environmental laws could become more stringent over time imposing greater compliance costs and increasing risks and penalties associated with violations, which could harm our business.

We face increasing complexity in our product design as we adjust to new and future requirements relating to the material composition of our products, including the restrictions on lead and other hazardous substances that apply to specified electronic products put on the market in the European Union, China and California. Other countries, including at the federal and state levels in the United States, are also considering similar laws and regulations. Certain electronic products that we maintain in inventory may be rendered obsolete if they are not in compliance with such laws and regulations, which could negatively impact our ability to generate revenue from those products. Although we cannot predict the ultimate impact of any such new laws and regulations, they will likely result in additional costs, or in the worst case decreased revenue, and could even require that we redesign or change how we manufacture our products. Such redesigns result in additional costs and possible delayed or lost revenue.

The trading price of our common stock is subject to fluctuation and is likely to be volatile.

The trading price of our common stock may fluctuate significantly in response to a number of factors, some of which are beyond our control, including:

· actual or anticipated declines in operating results;

· changes in financial estimates or recommendations by securities analysts;

· the institution of legal proceedings against us or significant developments in such proceedings;

· announcements by us or our competitors of financial results, new products, significant technological innovations, contracts, acquisitions, strategic relationships, joint ventures, capital commitments or other events;

· changes in industry estimates of demand for Very Fast SRAM products;

· the gain or loss of significant orders or customers;

· recruitment or departure of key personnel; and

· market conditions in our industry, the industries of our customers and the economy as a whole.

In recent years the stock market in general, and the market for technology stocks in particular, have experienced extreme price fluctuations, which have often been unrelated to the operating performance of affected companies. The market price of our common stock might experience significant fluctuations in the future, including fluctuations unrelated to our performance. These fluctuations could materially adversely affect our business relationships, our ability to obtain future financing on favorable terms or otherwise harm our business. In addition, in the past, securities class action litigation has often been brought against a company following periods of volatility

38

in the market price of its securities. This risk is especially acute for us because the extreme volatility of market prices of technology companies has resulted in a larger number of securities class action claims against them. Due to the potential volatility of our stock price, we may in the future be the target of similar litigation. Securities litigation could result in substantial costs and divert management's attention and resources. This could harm our business and cause the value of our stock to decline.

Use of a portion of our cash reserves to repurchase shares of our common stock presents potential risks and disadvantages to us and our stockholders. 

From November 2008 through December 2017, we repurchased and retired an aggregate of 11,983,942 shares of our common stock at a total cost of $60.6 million, including 3,846,153 shares repurchased at a total cost of $25 million pursuant to a modified “Dutch auction” self-tender offer that we completed in August 2014 and additional shares repurchased in the open market pursuant to our stock repurchase program.  At December 31, 2017, we had outstanding authorization from our Board of Directors to purchase up to an additional $4.4 million of our common stock from time to time under our repurchase program. Although our Board has determined that these repurchases are in the best interests of our stockholders, they expose us to certain risks including: 

· the risks resulting from a reduction in the size of our “public float,” which is the number of shares of our common stock that are owned by non-affiliated stockholders and available for trading in the securities markets, which may reduce the volume of trading in our shares and result in reduced liquidity and, potentially, lower trading prices; 

· the risk that our stock price could decline and that we would be able to repurchase shares of our common stock in the future at a lower price per share than the prices we have paid in our tender offer and repurchase program; and

· the risk that the use of a portion of our cash reserves for this purpose has reduced, or may reduce, the amount of cash that would otherwise be available to pursue potential cash acquisitions or other strategic business opportunities.

Our executive officers, directors and entities affiliated with them hold a substantial percentage of our common stock.

As of January 31, 2018, our executive officers, directors and entities affiliated with them beneficially owned approximately 34% of our outstanding common stock. As a result, these stockholders will be able to exercise substantial influence over, and may be able to effectively control, matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, which could have the effect of delaying or preventing a third party from acquiring control over or merging with us.

The provisions of our charter documents might inhibit potential acquisition bids that a stockholder might believe are desirable, and the market price of our common stock could be lower as a result.

Our Board of Directors has the authority to issue up to 5,000,000 shares of preferred stock. Our Board of Directors can fix the price, rights, preferences, privileges and restrictions of the preferred stock without any further vote or action by our stockholders. The issuance of shares of preferred stock might delay or prevent a change in control transaction. As a result, the market price of our common stock and the voting and other rights of our stockholders might be adversely affected. The issuance of preferred stock might result in the loss of voting control to other stockholders. We have no current plans to issue any shares of preferred stock. Our charter documents also contain other provisions, which might discourage, delay or prevent a merger or acquisition, including:

· our stockholders have no right to remove directors without cause;

· our stockholders have no right to act by written consent;

· our stockholders have no right to call a special meeting of stockholders; and

39

· stockholders must comply with advance notice requirements to nominate directors or submit proposals for consideration at stockholder meetings.

These provisions could also have the effect of discouraging others from making tender offers for our common stock. As a result, these provisions might prevent the market price of our common stock from increasing substantially in response to actual or rumored takeover attempts. These provisions might also prevent changes in our management.

40

Item 2.Unregistered Sales of Equity Securities and Use of Proceeds

Stock Repurchase Program

Our Board of Directors has authorized us to repurchase, at management’s discretion, shares of our common stock.  Under the repurchase program, we may repurchase shares from time to time on the open market or in private transactions. The specific timing and amount of the repurchases will be dependent on market conditions, securities law limitations and other factors. The repurchase program may be suspended or terminated at any time without prior notice.  During the quarter ended December 31, 2017,  we did not repurchase any of our shares under the repurchase program.

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company And Summary Of Significant Accounting Policies

NOTE 1-THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NOTE 1—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation

The accompanying unaudited condensed consolidated financial statements of GSI Technology, Inc. and its subsidiaries (“GSI” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission.  Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for annual financial statements.  These interim financial statements contain all adjustments (which consist of only normal, recurring adjustments) that are, in the opinion of management, necessary to state fairly the interim financial information included therein.  The Company believes that the disclosures are adequate to make the information not misleading.  However, these financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2017.

The consolidated results of operations for the nine months ended December 31, 2017 are not necessarily indicative of the results to be expected for the entire fiscal year.

Significant accounting policies

The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2017.

Recent accounting pronouncements

In May 2017, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2017-09, “Scope of Modification Accounting”.  ASU 2017-09 amends the scope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. This guidance clarifies that an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the fair value of the award, (ii) the vesting conditions of the award, and (iii) the classification of the award as an equityinstrument or liability instrument. The standard is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017, including adoption in any interim period.  The Company is currently evaluating the impact of this standard on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The standard eliminates the second step in the goodwill impairment test which requires an entity to determine the implied fair value of the reporting unit’s goodwill.  Instead, an entity should recognize an impairment loss if the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, with the impairment loss not to exceed the amount of goodwill allocated to the reporting unit. The standard is effective for annual and interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019, with early adoption permitted.  The Company does not anticipate the adoption of this guidance to have a material impact on its consolidated financial statements and related disclosures.

In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash”. ASU 2016-18 requires entities to include in their cash and cash-equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash and restricted cash equivalents. As a result, companies will no longer present transfers between cash and cash equivalents, and restricted cash and restricted cash equivalents in the statement of cash flows. The guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact this new guidance will have on its consolidated statement of cash flows.

In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.” ASU 2016-16 requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs and eliminates the exception for an intra-entity transfer of an asset other than inventory.  The Company adopted ASU 2016-16 in the quarter ended June 30, 2017.  ASU 2016-16 is applied on a modified retrospective basis in the period of adoption.   The adoption of this guidance resulted in a derecognition of a prepaid tax asset of $595,000 related to a prior period intra-entity asset transfer, with an offsetting reduction to retained earnings.  Because of the Company’s valuation allowance in the United States, there was no change to the Company’s net deferred tax assets.  The derecognition of the prepaid tax asset as of April 1, 2017 decreased the Company’s income tax expense by $11,000 in each of the quarters ended June 30, 2017, September 30, 2017 and December 31, 2017 and is projected to decrease the Company’s fiscal 2018 tax expense by $43,000.

In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments”. ASU 2016-15 adds or clarifies guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. The amendments in the update provide guidance on eight specific cash flow issues, and are effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The amendments to the guidance should be applied using a retrospective transition method for each period presented and, if it is impracticable to apply all of the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company is currently evaluating the impact this new guidance will have on its consolidated statement of cash flows.

In June 2016, the FASB issued ASU 2016-13,  “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For trade and other receivables, loans, and other financial instruments, the Company will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted beginning April 1, 2019. Application of the amendments is through a cumulative-effect adjustment to retained earnings as of the effective date. The Company is currently evaluating the impact of this standard on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The Company adopted ASU 2016-09 in the quarter ended June 30, 2017.  The Company has elected to continue to estimate forfeitures as part of the compensation cost of equity awards.  ASU 2016-09 is applied prospectively to all excess tax benefits and tax deficiencies resulting from settlements after the date of adoption.  The adoption of ASU 2016-09 resulted in an increase to the net operating loss carryforward deferred tax asset and a corresponding increase in the valuation allowance of $654,000 attributable to excess tax benefits not previously recognized as they did not reduce income taxes payable.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. All leases create an asset and a liability for the lessee in accordance with FASB Concepts Statement No. 6, “Elements of Financial Statements,” and, therefore, recognition of those lease assets and lease liabilities represents a change of previous GAAP, which did not require lease assets and lease liabilities to be recognized for most leases.  This ASU is effective for annual and interim periods beginning after December 15, 2018.  Early adoption is permitted. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous GAAP. Although the Company is currently evaluating the impact the pronouncement will have on its consolidated financial statements and related disclosures, the Company expects that most of its operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets upon adoption.

In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income and simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. The accounting standard update also updates certain presentation and disclosure requirements. This accounting standard update will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years,and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” This standard update intends to simplify the subsequent measurement of inventory, excluding inventory accounted for under the last-in, first-out or the retail inventory methods. The update replaces the current lower of cost or market test with a lower of cost and net realizable value test. Under the current guidance, market could be replacement cost, net realizable value or net realizable value less an approximately normal profit margin. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.  The Company adopted ASU 2015-11 in the quarter ended June 30, 2017.  Implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)" and has subsequently issued several supplemental and/or clarifying ASUs (collectively, "ASC 606"). The new accounting standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The accounting standard is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2017. The Company plans to adopt ASC 606 on April 1, 2018 using the modified retrospective transition method with the cumulative effect of initial adoption, if any, recognized in opening retained earnings on the adoption date. Almost all of the Company’s purchase orders, contracts or purchase agreements do not contain performance obligations other than delivery of the agreed upon product, with title transfer occurring at the time of shipment subject to estimated allowance for distributor price adjustments and rights of return. Thus, the Company generally recognizes revenue upon shipment of the product. The Company has historically deferred recognition of revenue on shipments to its distributors that have ship from stock and debit and price protection rights due to a lack of a fixed and determinable price that could be reasonably estimated. The Company has been revising certain of its distribution agreements to eliminate ship from stock and debits and price protection in order to eliminate any uncertainty in regards to a final selling price and to establish a selling price that is fixed and determinable at the time of shipment to the distributor.  Assuming all other revenue recognition criteria have been met, it is likely that the new guidance would require the Company to recognize revenue and cost relating to distributor sales upon shipment to the distributor, subject to estimated allowance for distributor price adjustments and rights of return. The Company is currently in the process of assessing the impact this guidance is expected to have upon adoption, which includes determining the impact of the new guidance on the Company’s revenue recognition practices, business processes, internal controls and the additional disclosures which may be required upon the adoption of ASC 606.

Goodwill.

NOTE 4-GOODWILL.

NOTE 4—GOODWILL

Goodwill represents the difference between the purchase price and the estimated fair value of the identifiable assets acquired and liabilities assumed in a business combination. The Company tests for goodwill impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the asset is more likely than not impaired. The Company has one reporting unit. The Company assesses goodwill for impairment on an annual basis on the last day of February in the fourth quarter of its fiscal year.

The Company had a goodwill balance of $8.0 million as of both March 31, 2017 and December 31, 2017. The goodwill resulted from the acquisition of MikaMonu Group Ltd. in fiscal 2016.

The Company utilized a two-step quantitative analysis to complete its annual impairment test during the fourth quarter of fiscal 2017 and concluded that there was no impairment, as the fair value of its sole reporting unit exceeded its carrying value. The Company determined that the second step of the impairment test was not necessary. No triggering event took place subsequent to the fiscal 2017 annual assessment that necessitated a quantitative impairment analysis for the Company’s one reporting unit.

NOTE 5—INCOME TAXES

The current portion of the Company’s unrecognized tax benefits was $0 at both December 31, 2017 and March 31, 2017. The long-term portion at December 31, 2017 and March 31, 2017 was $823,000 and $244,000, respectively, of which the timing of the resolution is uncertain.  As of December 31, 2017, $1.3 million of unrecognized tax benefits had been recorded as a reduction to net deferred tax assets.  As of December 31,2017 and March 31, 2017, the Company’s net deferred tax assets of $5.6 million and $8.9 million, respectively, were subject to a full valuation allowance.

On December 22, 2017, the “Tax Cuts and Jobs Act” ("H.R. 1") was signed into law, significantly impacting several sections of the Internal Revenue Code. This new law includes significant changes to the U.S. corporate income tax system, including a permanent reduction in the corporate income tax rate from 35% to 21%, limitations on the deductibility of interest expense and executive compensation and the transition of U.S. international taxation from a worldwide tax system to a territorial tax system.  The Company remeasured all deferred tax assets and liabilities as of December 22, 2017, based on the provisions of H.R. 1. This new legislation resulted in a estimated tax provision of $639,000 in the quarter ended December 31, 2017 related to the transition tax associated with deemed repatriation of foreign earnings. In addition, as a result of provisions in the new legislation related to indefinite lived net operating loss carryovers and the refundability of minimum tax credit carryovers, the Company recorded a deferred tax benefit related to a valuation allowance release of $99,000 in the quarter ended December 31, 2017. Finally, the Company recorded a liability for taxes payable of $68,000 at December 31, 2017 that will be paid over a period of up to eight years.

This original estimate may be materially impacted by a number of additional considerations, including but not limited to the issuance of the final regulations, the Company’s ongoing analysis of the new law and the Company’s actual earnings for the fiscal year ending March 31, 2018.

Management believes that within the next twelve months the Company will have no reduction in uncertain tax benefits, including interest and penalties, related to positions taken with respect to credits and loss carryforwards on previously filed tax returns.

The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the provision for income taxes in the Condensed Consolidated Statements of Operations.

The Company is subject to taxation in the United States and various state and foreign jurisdictions.  Fiscal years 2013 through 2017 remain open to examination by federal tax authorities, and fiscal years 2011 through 2017 remain open to examination by California tax authorities.

The Company’s estimated annual effective income tax rate was approximately (13.7%) and 7.4% as of December 31, 2017 and 2016, respectively. The annual effective tax rates as of December 31, 2017 and 2016 vary from the United States statutory income tax rate primarily due to valuation allowances in the United States, whereby pre-tax losses do not result in the recognition of corresponding income tax benefits and expenses, the foreign tax differential, and the impact of new tax reform.

Fair value measurements

Authoritative accounting guidance for fair value measurements provides a framework for measuring fair value and related disclosures.  The guidance applies to all financial assets and financial liabilities that are measured on a recurring basis.  The guidance requires fair value measurement to be classified and disclosed in one of the following three categories:

Level 1: Valuations based on quoted prices in active markets for identical assets and liabilities.  The fair value of available-for-sale securities included in the Level 1 category is based on quoted prices that are readily and regularly available in an active market.  As of December 31, 2017, the Level 1 category included money market funds of$9.5 million, which were included in cash and cash equivalents on the Condensed Consolidated Balance Sheets.

Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly. The fair value of available-for-sale securities included in the Level 2 category is based on the market values obtained from an independent pricing service that were evaluated using pricing models that vary by asset class and may incorporate available trade, bid and other market information and price quotes from well-established independent pricing vendors and broker-dealers. As of December 31, 2017, the Level 2 category included short-term investments of $17.0 million and long-term investments of $8.2 million, which were comprised of certificates of deposit, corporate debt securities and government and agency securities.

Level 3: Valuations based on inputs that are unobservable and involve management judgment and the reporting entity’s own assumptions about market participants and pricing.  As of December 31, 2017, the Company’s Level 3 financial instruments measured at fair value on the Condensed Consolidated Balance Sheets consisted of the contingent consideration liability related to the acquisition of MikaMonu. The fair value of the contingent consideration liability was initially determined as of the acquisition date using unobservable inputs.  These inputs include the estimated amount and timing of future cash flows, the probability of success (achievement of the various contingent events) and a risk-adjusted discount rate of approximately 14.8% used to adjust the probability-weighted cash flows to their present value.  Subsequent to the acquisition date, at each reporting period, the contingent consideration liability is re-measured to fair value with changes recorded in selling, general and administrative expenses in the Consolidated Statements of Operations. The change in fair value for the three month and nine month periods ended December 31, 2017 were $41,000 and $121,000, respectively.

The fair value of financial assets measured on a recurring basis is as follows (in thousands):

Short-term and long-term investments

All of the Company’s short-term and long-term investments are classified as available-for-sale.  Available-for-sale debt securities with maturities greater than twelve months are classified as long-term investments when they are not intended for use in current operations.  Investments in available-for-sale securities are reported at fair value with unrecognized gains (losses), net of tax, as a component of accumulated other comprehensive income (loss) in the Condensed Consolidated Balance Sheets.  The Company had money market funds of $9.5 million and $6.3 million at December 31, 2017 and March 31, 2017, respectively, included in cash and cash equivalents on the Condensed Consolidated Balance Sheets.  The Company monitors its investments for impairment periodically and records appropriate reductions in carrying values when declines are determined to be other-than-temporary.

The following table summarizes the Company’s available-for-sale investments:

The Company’s investment portfolio consists of both corporate and governmental securities that have a maximum maturity of three years. All unrealized gains and losses are due to changes in interest rates and bond yields.  Subject to normal credit risks, the Company has the ability to realize the full value of all these investments upon maturity.

The deferred tax asset related to unrecognized gains and losses on short-term and long-term investments was $21,000 and $17,000 at December 31, 2017 and March 31, 2017, respectively.

As of December 31, 2017, contractual maturities of the Company’s available-for-sale investments were as follows:

			Fair

Maturing in one to three years		8,250		8,199

The Company classifies its short-term investments as “available-for-sale” as they are intended to be available for use in current operations.

NOTE 7-COMMITMENTS AND CONTINGENCIES

NOTE 7—COMMITMENTS AND CONTINGENCIES

Indemnification obligations

The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify the other party with respect to certain matters. Typically, these obligations arise in the context of contracts entered into by the Company, under which the Company 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 and certain intellectual property rights. In each of these circumstances, payment by the Company is 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 claims. Further, the Company’s obligations under these agreements may be limited in terms of 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.

It is not possible to predict the maximum potential amount of future payments that may be required under these or similar agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material effect on its business, financial condition, cash flows or results of operations.

Product warranties

The Company warrants its products to be free of defects generally for a period of three years. The Company estimates its warranty costs based on historical warranty claim experience and includes such costs in cost of revenues. Warranty costs and the accrued warranty liability were not material as of December 31, 2017 and March 31, 2017 and for the three months and nine months ended December 31, 2017 or 2016.

As stock-based compensation expense recognized in the Condensed Consolidated Statement of Operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures in accordance with authoritative guidance.  The Company estimates forfeitures at the time of grant and revises the original estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

No tax benefit related to stock-based compensation was recognized in the three months or nine months ended December 31, 2017 or December 31, 2016 due to a full valuation allowance. There were no windfall tax benefits realized from exercised stock options in either of these periods.   Compensation cost capitalized within inventory at December 31, 2017 was immaterial. As of December 31, 2017, the Company’s total unrecognized compensation cost was $4.2 million, which will be recognized over a weighted average period of 2.18 years. The Company calculated the fair value of stock-based awards in the periods presented using the Black-Scholes option pricing model and the following weighted average assumptions:

The Company And Summary Of Significant Accounting Policies

Basis of presentation

Basis of presentation

The accompanying unaudited condensed consolidated financial statements of GSI Technology, Inc. and its subsidiaries (“GSI” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission.  Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for annual financial statements.  These interim financial statements contain all adjustments (which consist of only normal, recurring adjustments) that are, in the opinion of management, necessary to state fairly the interim financial information included therein.  The Company believes that the disclosures are adequate to make the information not misleading.  However, these financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2017.

The consolidated results of operations for the nine months ended December 31, 2017 are not necessarily indicative of the results to be expected for the entire fiscal year.

Recent accounting pronouncements

Recent accounting pronouncements

In May 2017, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2017-09, “Scope of Modification Accounting”.  ASU 2017-09 amends the scope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. This guidance clarifies that an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the fair value of the award, (ii) the vesting conditions of the award, and (iii) the classification of the award as an equityinstrument or liability instrument. The standard is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017, including adoption in any interim period.  The Company is currently evaluating the impact of this standard on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The standard eliminates the second step in the goodwill impairment test which requires an entity to determine the implied fair value of the reporting unit’s goodwill.  Instead, an entity should recognize an impairment loss if the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, with the impairment loss not to exceed the amount of goodwill allocated to the reporting unit. The standard is effective for annual and interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019, with early adoption permitted.  The Company does not anticipate the adoption of this guidance to have a material impact on its consolidated financial statements and related disclosures.

In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash”. ASU 2016-18 requires entities to include in their cash and cash-equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash and restricted cash equivalents. As a result, companies will no longer present transfers between cash and cash equivalents, and restricted cash and restricted cash equivalents in the statement of cash flows. The guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact this new guidance will have on its consolidated statement of cash flows.

In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.” ASU 2016-16 requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs and eliminates the exception for an intra-entity transfer of an asset other than inventory.  The Company adopted ASU 2016-16 in the quarter ended June 30, 2017.  ASU 2016-16 is applied on a modified retrospective basis in the period of adoption.   The adoption of this guidance resulted in a derecognition of a prepaid tax asset of $595,000 related to a prior period intra-entity asset transfer, with an offsetting reduction to retained earnings.  Because of the Company’s valuation allowance in the United States, there was no change to the Company’s net deferred tax assets.  The derecognition of the prepaid tax asset as of April 1, 2017 decreased the Company’s income tax expense by $11,000 in each of the quarters ended June 30, 2017, September 30, 2017 and December 31, 2017 and is projected to decrease the Company’s fiscal 2018 tax expense by $43,000.

In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments”. ASU 2016-15 adds or clarifies guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. The amendments in the update provide guidance on eight specific cash flow issues, and are effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The amendments to the guidance should be applied using a retrospective transition method for each period presented and, if it is impracticable to apply all of the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company is currently evaluating the impact this new guidance will have on its consolidated statement of cash flows.

In June 2016, the FASB issued ASU 2016-13,  “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For trade and other receivables, loans, and other financial instruments, the Company will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted beginning April 1, 2019. Application of the amendments is through a cumulative-effect adjustment to retained earnings as of the effective date. The Company is currently evaluating the impact of this standard on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The Company adopted ASU 2016-09 in the quarter ended June 30, 2017.  The Company has elected to continue to estimate forfeitures as part of the compensation cost of equity awards.  ASU 2016-09 is applied prospectively to all excess tax benefits and tax deficiencies resulting from settlements after the date of adoption.  The adoption of ASU 2016-09 resulted in an increase to the net operating loss carryforward deferred tax asset and a corresponding increase in the valuation allowance of $654,000 attributable to excess tax benefits not previously recognized as they did not reduce income taxes payable.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. All leases create an asset and a liability for the lessee in accordance with FASB Concepts Statement No. 6, “Elements of Financial Statements,” and, therefore, recognition of those lease assets and lease liabilities represents a change of previous GAAP, which did not require lease assets and lease liabilities to be recognized for most leases.  This ASU is effective for annual and interim periods beginning after December 15, 2018.  Early adoption is permitted. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous GAAP. Although the Company is currently evaluating the impact the pronouncement will have on its consolidated financial statements and related disclosures, the Company expects that most of its operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets upon adoption.

In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income and simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. The accounting standard update also updates certain presentation and disclosure requirements. This accounting standard update will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years,and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” This standard update intends to simplify the subsequent measurement of inventory, excluding inventory accounted for under the last-in, first-out or the retail inventory methods. The update replaces the current lower of cost or market test with a lower of cost and net realizable value test. Under the current guidance, market could be replacement cost, net realizable value or net realizable value less an approximately normal profit margin. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.  The Company adopted ASU 2015-11 in the quarter ended June 30, 2017.  Implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)" and has subsequently issued several supplemental and/or clarifying ASUs (collectively, "ASC 606"). The new accounting standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The accounting standard is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2017. The Company plans to adopt ASC 606 on April 1, 2018 using the modified retrospective transition method with the cumulative effect of initial adoption, if any, recognized in opening retained earnings on the adoption date. Almost all of the Company’s purchase orders, contracts or purchase agreements do not contain performance obligations other than delivery of the agreed upon product, with title transfer occurring at the time of shipment subject to estimated allowance for distributor price adjustments and rights of return. Thus, the Company generally recognizes revenue upon shipment of the product. The Company has historically deferred recognition of revenue on shipments to its distributors that have ship from stock and debit and price protection rights due to a lack of a fixed and determinable price that could be reasonably estimated. The Company has been revising certain of its distribution agreements to eliminate ship from stock and debits and price protection in order to eliminate any uncertainty in regards to a final selling price and to establish a selling price that is fixed and determinable at the time of shipment to the distributor.  Assuming all other revenue recognition criteria have been met, it is likely that the new guidance would require the Company to recognize revenue and cost relating to distributor sales upon shipment to the distributor, subject to estimated allowance for distributor price adjustments and rights of return. The Company is currently in the process of assessing the impact this guidance is expected to have upon adoption, which includes determining the impact of the new guidance on the Company’s revenue recognition practices, business processes, internal controls and the additional disclosures which may be required upon the adoption of ASC 606.
