Accounting Policies [Abstract]

NOTE 1—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NOTE 1—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company

GSI Technology, Inc. (the "Company") was incorporated in California in March 1995 and reincorporated in Delaware on June 9, 2004. The Company is a provider of "Very Fast" SRAM products and LLDRAM products that are incorporated primarily in high-performance networking and telecommunications equipment, such as routers, switches, wide area network infrastructure equipment, wireless base stations and network access equipment. In addition, the Company serves the ongoing needs of the military, industrial, test equipment and medical markets for high-performance SRAMs.

Accounting principles

The consolidated financial statements and accompanying notes were prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").

Basis of consolidation

The consolidated financial statements include the accounts of the Company's three wholly-owned subsidiaries, GSI Technology Holdings, Inc., GSI Technology (BVI), Inc. and GSI Technology Taiwan, Inc. All significant inter-company transactions and balances have been eliminated in consolidation.

Use of estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates are inherent in the preparation of the consolidated financial statements and include revenue recognition, obsolete and excess inventory, the valuation allowance on deferred tax assets, the valuation of equity instruments and stock-based compensation. Actual results could differ from those estimates.

Risk and uncertainties

The Company buys all of its SRAM and LLDRAM wafers, integral components of its products, from single suppliers and is also dependent on independent suppliers to assemble and test its products. During the years ended March 31, 2013, 2012 and 2011, all of the wafers used in the Company's SRAM and LLDRAM products were supplied by Taiwan Semiconductor Manufacturing Company Limited, or TSMC, and Powerchip Technology Corporation, or Powerchip, respectively. If these suppliers fail to satisfy the Company's requirements on a timely basis at competitive prices, the Company could suffer manufacturing delays, a possible loss of revenues, or higher cost of revenues, any of which could adversely affect operating results.

A majority of the Company's net revenues come from sales to customers in the networking and telecommunications equipment industry. A decline in demand in this industry could have a material adverse affect on the Company's operating results and financial condition.

Because much of the manufacturing and testing of the Company's products is conducted in Taiwan, its 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 the Company's 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 the Company's and its suppliers' ability to do business and operate facilities in Taiwan. If any of these risks were to occur, the Company's business could be harmed.

Some of the Company's suppliers and the Company's two principal operations are located near fault lines. In the event of a major earthquake or other natural disaster near the facilities of any of these suppliers or the Company, the Company's business could be harmed.

From time to time, the Company is involved in legal actions. The Company currently is a party to pending legal proceedings which it is defending aggressively. See Note 6 for additional information regarding this pending litigation. There are many uncertainties associated with any litigation, and the Company may not prevail. If information becomes available that causes us to determine that a loss in any of our pending litigation, or the settlement of such litigation, is probable, and we can reasonably estimate the loss associated with such events, we will record the loss in accordance with GAAP. However, the actual liability in any such litigation may be materially different from our estimates, which could require us to record additional costs.

Revenue recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectibility of the resulting receivable is reasonably assured. Under these criteria, revenue from the sale of products is generally recognized upon shipment according to the Company's shipping terms, net of accruals for estimated sales returns and allowances based on historical experience. Sales to distributors are made under agreements allowing for returns or credits. Distributors have stock rotation, price protection and ship from stock pricing adjustment rights and the Company therefore defers recognition of revenue on sales to distributors until products are resold by the distributor. The Company is unable to reasonably estimate the inventory that could be returned pursuant to the stock rotation rights. In light of possible changes to sales prices resulting from price protection and price adjustment rights granted, we are unable to reasonably estimate possible changes and the resulting sales price to the distributor is not fixed or determinable until the final sale to the end user. For sales to consignment warehouses, who purchase products from the Company for use by contract manufacturers, revenues are recognized upon delivery to the contract manufacturer.

Cash and cash equivalents

Cash and cash equivalents include cash in demand accounts and highly liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase, stated at cost, which approximates their fair market value.

Short-term and long-term investments

All of the Company's short-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" in the Consolidated Balance Sheets. The Company monitors its investments for impairment periodically and records appropriate reductions in carrying values when the declines are determined to be other-than-temporary.

Concentration of credit risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash, cash equivalents, short-term and long-term investments and accounts receivable. The Company places its cash primarily in checking, certificate of deposit, and money market accounts with reputable financial institutions. The Company's accounts receivable are derived primarily from revenue earned from customers located in the U.S. and Asia. The Company performs ongoing credit evaluations of its customers' financial condition and, generally, requires no collateral from its customers. The Company maintains an allowance for doubtful accounts receivable based upon the expected collectibility of accounts receivable. There were no write offs in the years ended March 31, 2013, 2012 or 2011.

In fiscal 2013, 2012 and 2011, sales to the Company's top 10 customers accounted for approximately 91%, 92% and 91% of net revenues, respectively. At March 31, 2013, six customers accounted for 20%, 16%, 15%, 10%, 10% and 10% of accounts receivable, and for the year then ended, four customers accounted for 27%, 14%, 11% and 10% of net revenues. At March 31, 2012, five customers accounted for 19%, 16%, 12%, 11% and 10% of accounts receivable, and for the year then ended, four customers accounted for 20%, 20%, 11% and 11% of net revenues.. At March 31, 2011, three customers accounted for 21%, 17% and 13% of accounts receivable, and for the year then ended, four customers accounted for 19%, 17%, 12% and 11% of net revenues.

Inventories

Inventories are stated at the lower of cost or market value, cost being determined on a weighted average basis. Inventory write-down allowances are established when conditions indicate that the selling price could be less than cost due to physical deterioration, obsolescence, changes in price levels, or other causes. These allowances, once recorded, result in a new cost basis for the related inventory. These allowances are also considered for excess inventory generally based on inventory levels in excess of 12 months of forecasted demand, as estimated by management, for each specific product. The allowance is not reversed until the inventory is sold or disposed of.

Property and equipment, net

Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as presented below:

	Software	3 to 5 years
	Computer and other equipment	5 to 10 years
	Building and building improvements	10 to 25 years
	Furniture and fixtures	7 years

Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful lives of the assets or the remaining lease term of the respective assets. Gains or losses on disposals of property and equipment are recorded within income from operations. Costs of repairs and maintenance are typically included as part of operating expenses unless they are incurred in relation to major improvements to existing property and equipment, at which time they are capitalized.

Impairment of long-lived assets

Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that their net book value may not be recoverable. If the sum of the expected future cash flows (undiscounted and before interest) from the use of the assets is less than the net book value of the asset an impairment exists and the amount of the impairment loss, if any, will generally be measured as the difference between net book value of the assets and their estimated fair values. There were no impairment losses recognized during the years ended March 31, 2013, 2012 or 2011.

Intangible Assets

Intangible assets are amortized over their estimated useful lives, generally on a straight-line basis over five to nine years. The Company reviews identifiable amortizable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the carrying value of the asset over its fair value.

Research and development

Research and development expenses are related to new product designs, including, salaries, stock-based compensation, contractor fees, and allocation of corporate costs and are charged to the statement of operations as incurred.

Income taxes

The Company accounts for income taxes under the liability method, whereby deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when it is more likely than not that the deferred tax asset will not be realized.

Authoritative guidance prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return (including a decision whether to file or not to file a return in a particular jurisdiction). Under the guidance, the financial statements will reflect expected future tax consequences of such positions presuming the taxing authorities' full knowledge of the position and all relevant facts, but without considering time values. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation process, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement.

Shipping and handling costs

The Company records costs related to shipping and handling in cost of revenues.

Advertising expense

Advertising costs are charged to expense in the period incurred. Advertising expense was $10,000, $8,000 and $6,000 for the years ended March 31, 2013, 2012, and 2011, respectively.

Foreign currency transactions

The U.S. dollar is the functional currency for all of the Company's foreign operations. Foreign currency transaction gains and losses, resulting from transactions denominated in currencies other than U.S. dollars are included in the statements of operations. These gains and losses were not material for the years ended March 31, 2013, 2012 or 2011.

Segments

The Company operates in one segment for the design, development and sale of integrated circuits.

Accounting for stock-based compensation

Under authoritative guidance, stock-based compensation expense recognized in the statement of operations is based on options ultimately expected to vest, reduced by the amount of estimated forfeitures. The Company chose the straight-line method of allocating compensation cost over the requisite service period of the related award according to authoritative guidance. The Company calculated the expected term based on the historical average period of time that options were outstanding as adjusted for expected changes in future exercise patterns, which, for options granted in fiscal 2013, 2012 and 2011 resulted in an expected term of approximately five years. The Company used historical volatility to estimate of expected volatility in fiscal 2013. The Company based its estimate of expected volatility on the estimated volatility of similar entities whose share prices are publicly available for in fiscal 2012 and 2011. The risk-free interest rate is based on the U.S. Treasury yields in effect at the time of grant for periods corresponding to the expected life of the options. The dividend yield is 0%, based on the fact that the Company has never paid dividends and has no present intention to pay dividends. Changes to these assumptions may have a significant impact on the results of operations.

Authoritative guidance requires cash flows, if any, resulting from the tax benefits from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) to be classified as financing cash flows.

Comprehensive income

Comprehensive income is defined to include all changes in equity during a period except those resulting from investments by owners and distributions to owners. For the years ended March 31, 2013, 2012 and 2011, comprehensive income was $3,803,000, $6,761,000 and $18,769,000, respectively.

Recent accounting pronouncements

In June 2011, the Financial Accounting Standards Board ("FASB") amended its guidance on the presentation of comprehensive income. Under the amended guidance, an entity has the option to present comprehensive income in either one continuous statement or two consecutive financial statements. A single statement must present the components of net income and total net income, the components of other comprehensive income and total other comprehensive income, and a total for comprehensive income. In a two-statement approach, an entity must present the components of net income and total net income in the first statement. That statement must be immediately followed by a financial statement that presents the components of other comprehensive income, a total for other comprehensive income, and a total for comprehensive income. The entity is also required to present on the face of its financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. The option under previous guidance that permitted the presentation of components of other comprehensive income as part of the statement of changes in stockholders' equity has been eliminated. In December 2011, the FASB further amended its guidance to defer changes related to the presentation of reclassification adjustments indefinitely as a result of concerns raised by stakeholders that the new presentation requirements would be difficult for preparers and add unnecessary complexity to financial statements. The amendment (other than the portion regarding the presentation of reclassification adjustments which, as noted above, has been deferred indefinitely) became effective during the quarter ended June 30, 2012. The amendment impacted the presentation of the consolidated financial statements but did not impact the Company's consolidated financial position, results of operations or cash flows.

U.S. income taxes and withholding taxes have not been provided on a cumulative total of $37.3 million of undistributed earnings for certain non-U.S. subsidiaries. The Company currently intends to reinvest these earnings in operations outside the U.S. No provision has been made for taxes that might be payable upon remittance of such earnings, nor is it practicable to determine the amount of such potential liability.

The current portion of the Company's unrecognized tax benefits at March 31, 2013 and 2012 was $0 and $599,000, respectively. The long-term portion at March 31, 2013 and 2012 was $2,803,000 and $1,835,000, respectively, of which the timing of the resolution is uncertain. As of March 31, 2013, $117,000 of unrecognized tax benefits had been recorded as a reduction to net deferred tax assets. It is possible, however, that some months or years may elapse before an uncertain position for which the Company has established a reserve is resolved. A reconciliation of unrecognized tax benefits is as follows:

	Year Ended March 31,
	2013			2012			2011
	(In thousands)
Unrecognized tax benefits, beginning of period	$	3,109		$	2,312		$	1,616

Unrecognized tax benefits, end of period	$	2,760		$	3,109		$	2,312

The unrecognized tax benefit balance as of March 31, 2013 of $2,760,000 would affect the Company's effective tax rate if recognized.

Management believes that it is reasonably possible that within the next twelve months the Company could have a reduction in uncertain tax benefits of up to $637,000, including interest and penalties, as a result of the lapse of statute of limitations.

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

The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. In the current year, we settled a State of California Franchise Tax Board income tax audit for the period from fiscal year 2002 through fiscal 2008 for an amount less than previously provided for. Fiscal years 2010 through 2013 remain open to examination by the federal tax authorities and fiscal years 2006 through 2013 remain open to examination by California.

Fair value measurements

Authoritative accounting guidance for fair value measurements provides a framework for measuring fair value and related disclosure. 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 March 31, 2013, the Level 1 category included money market funds of $10.4 million, which were included in cash and cash equivalents in the Consolidated Balance Sheet.

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 March 31, 2013, the Level 2 category included short-term investments of $26.1 million and long term-investments of $35.5 million, which were primarily 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 March 31, 2013, the Company had no Level 3 financial assets measured at fair value in the Consolidated Balance Sheet.

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 in the Condensed Consolidated Balance Sheets. The Company had money market funds of $10.4 million and $11.3 million at March 31, 2013 and March 31, 2012, respectively, included in cash and cash equivalents in the Condensed Consolidated Balance Sheet. The Company monitors its investments for impairment periodically and records appropriate reductions in carrying values when the 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 losses are due to changes in interest rates and bond yields. The Company has the ability to realize the full value of all these investments upon maturity.

At March 31, 2013, the deferred tax liability related to unrecognized gains and losses on short-term and long-term investments was $14,000. At March 31, 2012, the deferred tax liability related to unrecognized gains and losses on short-term and long-term investments was $26,000.

Operating leases

The Company leases office space and equipment under noncancelable operating leases with various expiration dates through August 2014. Rent expense for the years ended March 31, 2013, 2012 and 2011 was $373,000, $371,000 and $420,000, respectively. The terms of the facility leases provide for rental payments on a graduated scale. The Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not paid.

Future minimum lease payments under noncancelable operating leases with remaining lease terms in excess of one year at March 31, 2013 are as follows:

Royalty obligations

The Company has license agreements that require it to pay royalties on the sale of products using the licensed technology. Royalty expense for the years ended March 31, 2013, 2012 and 2011 was $65,000, $61,000 and $75,000, respectively, and was included within cost of revenues.

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 customarily agrees to hold the other party harmless against losses arising from a breach of representations and covenants related to such matters as title to assets sold 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 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. The Company believes that if it were to incur a loss in any of these matters, such loss should not have 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 were not significant for the years ended March 31, 2013, 2012 or 2011.

Legal proceedings

In March 2011, Cypress Semiconductor Corporation, a semiconductor manufacturer, filed a lawsuit against the Company in the United States District Court for the District of Minnesota alleging that the Company's products, including its SigmaDDR and SigmaQuad families of Very Fast SRAMs, infringe five patents held by Cypress. The complaint seeks unspecified damages for past infringement and a permanent injunction against future infringement.

On June 10, 2011, Cypress filed a complaint against the Company with the United States International Trade Commission (the “ITC”). The ITC complaint, as subsequently amended, alleges infringement by the Company of three of the five patents involved in the District Court case and one additional patent and also alleges infringement by three of our distributors and 11 of our customers who allegedly incorporate our SRAMs in their products. The ITC complaint seeks a limited exclusion order excluding the allegedly infringing SRAMs, and products containing them, from entry into the United States and permanent orders directing the Company and the other respondents to cease and desist from selling or distributing such products in the United States. On July 21, 2011, the ITC formally instituted an investigation in response to Cypress's complaint. Two of the distributor-respondents and ten of the customer-respondents were subsequently dismissed from the investigation. The evidentiary hearing took place in March 2012. On October 25, 2012, Chief Administrative Law Judge Charles E. Bullock issued his initial determination in which he held that the Company's SRAM products, and products containing them, do not infringe the asserted patent claims and that Cypress had failed to establish the existence of a domestic industry that practices the asserted patents. Because he found that the accused products do not infringe any of the asserted patent claims, Judge Bullock did not consider or rule on the additional arguments of the Company and the other respondents that the Cypress patents are invalid and unenforceable. Following a remand by the ITC, on February 25, 2012, Judge Bullock issued a supplemental initial determination finding that the asserted patents are enforceable and not invalid. Both the initial determination with respect to non-infringement and the lack of a domestic industry and the subsequent determination with respect to validity are currently under review by the full Commission. The target date for concluding the ITC investigation is June 25, 2013.

The Minnesota District Court case has been stayed pending the conclusion of the ITC proceeding. On May 1, 2013, Cypress filed a lawsuit in the United States District Court for the Northern District of California alleging infringement by our products of five additional Cypress patents. Like the Minnesota case, the complaint in the California lawsuit seeks unspecified damages for past infringement and a permanent injunction against future infringement.

The Company believes that Judge Bullock's initial determination of non-infringement in the ITC proceeding was correct and that the Company has strong defenses against Cypress’ claims in both District Court cases. The Company intends to continue to defend itself vigorously in these proceedings However, the litigation process is inherently uncertain, and the Company may not prevail. Patent litigation is particularly complex and can extend for a protracted period of time, which can substantially increase the cost of such litigation. The Company has not recorded any loss contingency during fiscal 2011, fiscal 2012 or fiscal 2013 in connection with these legal proceedings as the Company cannot predict their outcome and cannot estimate the likelihood or potential dollar amount of any adverse results. However, an unfavorable outcome in these proceedings could have a material adverse impact on the Company's financial position, results of operations or cash flows for the period in which the outcome occurs and in future periods.

NOTE 8—STOCK- BASED COMPENSATION

12 Months Ended

Mar. 31, 2013

Equity [Abstract]

NOTE 8—STOCK- BASED COMPENSATION

NOTE 8—STOCK- BASED COMPENSATION

The 2000 Stock Option Plan

In February 2001, the Company adopted the 2000 Stock Option Plan (the "2000 Plan"). The 2000 Plan provided for the granting of stock options and stock purchase rights to employees, consultants and directors of the Company. Options granted under the 2000 Plan could be either incentive stock options ("ISOs") or nonstatutory stock options ("NSOs"). In December 2006, the Company's board of directors authorized an additional 500,000 shares of the Company's common stock to be reserved for issuance under the 2000 Plan. As of March 31, 2008, the Company had reserved 3,500,000 shares of common stock for issuance under the 2000 Plan.

Options under the 2000 Plan could be granted for periods of up to ten years. However, in the case of ISOs granted to an optionee who, at the time the option was granted, owned stock representing more than 10% of the voting power of all classes of stock of the Company, the maximum term of an option was five years from the date of grant. The exercise price of an ISO or NSO could not be less than 100% and 85% of the estimated fair value of the shares as determined by the board of directors on the date of grant, respectively. However the exercise price of an ISO or NSO granted to a 10% or greater stockholder could not be less than 110% of the estimated fair value of the shares on the date of grant.

The 2007 Equity Incentive Plan

In January 2007, the Company's board of directors approved the 2007 Equity Incentive Plan, (the "Equity Plan"), which was subsequently approved by the Company's stockholders in March 2007. A total of 3,000,000 shares of common stock were authorized and reserved for issuance under the Equity Plan. This reserve automatically increases on April 1 of each year through 2017 by an amount equal to the smaller of (a) five percent of the number of shares of common stock issued and outstanding on the immediately preceding March 31, or (b) a lesser amount determined by the board of directors. Appropriate adjustments will be made in the number of authorized shares and other numerical limits in the Equity Plan and in outstanding awards to prevent dilution or enlargement of participants' rights in the event of a stock split or other change in the Company's capital structure. Shares subject to awards which expire or are cancelled or forfeited will again become available for issuance under the Equity Plan. The shares available will not be reduced by awards settled in cash or by shares withheld to satisfy tax withholding obligations. Only the net number of shares issued upon the exercise of stock appreciation rights or options exercised by means of a net exercise or by tender of previously owned shares will be deducted from the shares available under the Equity Plan.

To enable compensation provided in connection with certain types of awards intended to qualify as “performance-based” within the meaning of Section 162(m) of the Internal Revenue Code, the Equity Plan establishes limits on the maximum aggregate number of shares or dollar value for which awards may be granted to an employee in any fiscal year, as follows:

●	No more than 300,000 shares subject to stock options and stock appreciation rights.

●	No more than 100,000 shares subject to restricted stock and restricted stock unit awards.

●	For each full fiscal year of the Company contained in the performance period of the award, no more than 50,000 shares subject to performance share awards and other stock-based awards or more than $500,000 subject to performance unit awards and other cash-based awards.

In addition, to comply with applicable tax rules, the Equity Plan also limits the number of shares that may be issued upon the exercise of ISOs granted under the Equity Plan to 3,000,000, cumulatively increased on April 1 of each subsequent year through 2017, by an amount equal to the smallest of (a) five percent of the number of shares of common stock issued and outstanding on the immediately preceding March 31, (b) 1,500,000 shares, or (c) a lesser amount determined by the board of directors.

Upon the adoption of the Equity Plan in March 2007, the 2000 Plan was terminated, no further options were granted under the 2000 Plan, the 535,597 shares that remained reserved for grant under the 2000 Plan were cancelled, and all subsequent grants of stock options were made pursuant to the Equity Plan.

Awards may be granted under the Equity Plan to the Company's employees, including officers, directors, or consultants or those of any present or future parent or subsidiary corporation or other affiliated entity. To date, options granted to non-officer employees generally vest 25% on the first anniversary and subsequent anniversaries of the date of grant, while grants to officers vest in full four years after the anniversary date of the officer's employment that is closest to the date of grant. While the Company may grant ISOs only to employees, the Company may grant NSOs, stock appreciation rights, restricted stock purchase rights or bonuses, restricted stock units, performance shares, performance units and cash-based awards or other stock-based awards to any eligible participant. Non-employee director awards may be granted only to members of the Company's board of directors who, at the time of grant, are not employees. Deferred compensation awards may be granted only to officers, directors and selected members of management or highly compensated employees.

Only members of the board of directors who are not employees at the time of grant are eligible to participate in the nonemployee director awards component of the Equity Plan. The board or the compensation committee shall set the amount and type of nonemployee director awards to be awarded on a periodic, non-discriminatory basis. Nonemployee director awards may be granted in the form of NSOs, stock appreciation rights, restricted stock awards and restricted stock unit awards. Subject to adjustment for changes in the Company's capital structure, no nonemployee director may be awarded, in any fiscal year, one or more nonemployee director awards for more than 2,000 shares. However, the annual limit may be increased by the following additions: (i) an additional 10,000 shares in the fiscal year in which the nonemployee director is first appointed or elected to the board, (ii) an additional 2,000 shares in any fiscal year in which the nonemployee director is serving as the chairman or lead director of the board, (iii) an additional 1,000 shares in any fiscal year for each committee of the board on which the nonemployee director is then serving other than as chairman of the committee, and (iv) an additional 2,000 shares in any fiscal year for each committee of the board on which the nonemployee director is then serving as chairman of the committee.

In the event of a change in control as described in the Equity Plan, the acquiring or successor entity may assume or continue all or any awards outstanding under the Equity Plan or substitute substantially equivalent awards. Any awards which are not assumed or continued in connection with a change in control or exercised or settled prior to the change in control will terminate effective as of the time of the change in control. The administrator may provide for the acceleration of vesting of any or all outstanding awards upon such terms and to such extent as it determines, except that the vesting of all nonemployee director awards will automatically be accelerated in full. The Equity Plan also authorizes the administrator, in its discretion and without the consent of any participant, to cancel each or any outstanding award denominated in shares upon a change in control in exchange for a payment to the participant with respect to each vested share subject to the cancelled award of an amount equal to the excess of the consideration to be paid per share of common stock in the change in control transaction over the exercise price per share, if any, under the award.

The 2007 Employee Stock Purchase Plan

In January 2007, the board of directors approved the 2007 Employee Stock Purchase Plan (the "2007 Purchase Plan") which was subsequently approved by the Company's stockholders in March 2007. A total of 500,000 shares of the Company's common stock was authorized and reserved for sale under the 2007 Purchase Plan. In addition, the 2007 Purchase Plan provides for an automatic annual increase in the number of shares available for issuance under the plan on April 1 of each year beginning in 2008 and continuing through and including April 1, 2017 equal to the lesser of (1) one percent of the number of issued and outstanding shares of common stock on the immediately preceding March 31, (2) 250,000 shares or (3) a number of shares as the board of directors may determine. Appropriate adjustments will be made in the number of authorized shares and in outstanding purchase rights to prevent dilution or enlargement of participants' rights in the event of a stock split or other change in our capital structure. Shares subject to purchase rights which expire or are canceled will again become available for issuance under the 2007 Purchase Plan.

The Company's employees and employees of any parent or subsidiary corporation designated by the administrator will be eligible to participate in the 2007 Purchase Plan if they are customarily employed by us for more than 20 hours per week and more than five months in any calendar year. However, an employee may not be granted a right to purchase stock under the 2007 Purchase Plan if: (1) the employee immediately after such grant would own stock possessing 5% or more of the total combined voting power or value of all classes of our capital stock or of any parent or subsidiary corporation, or (2) the employee's rights to purchase stock under all of our employee stock purchase plans would accrue at a rate that exceeds $25,000 in value for each calendar year of participation in such plans.

The 2007 Purchase Plan is designed to be implemented through a series of sequential offering periods, generally six (6) months in duration beginning on the first trading day on or after May 1 and November 1 of each year. The administrator is authorized to establish additional or alternative sequential or overlapping offering periods and offering periods having a different duration or different starting or ending dates, provided that no offering period may have a duration exceeding 27 months.

Amounts accumulated for each participant under the 2007 Purchase Plan are used to purchase shares of the Company's common stock at the end of each offering period at a price generally equal to 85% of the lower of the fair market value of our common stock at the beginning of an offering period or at the end of the offering period. Prior to commencement of an offering period, the administrator is authorized to reduce, but not increase, this purchase price discount for that offering period, or, under circumstances described in the 2007 Purchase Plan, during that offering period. The maximum number of shares a participant may purchase in any six-month offering period is the lesser of (i) that number of shares determined by multiplying (x) 1,000 shares by (y) the number of months (rounded to the nearest whole month) in the offering period and rounding to the nearest whole share or (ii) that number of whole shares determined by dividing (x) the product of $2,083.33 and the number of months (rounded to the nearest whole month) in the offering period and rounding to the nearest whole dollar by (y) the fair market value of a share of our common stock at the beginning of the offering period. Prior to the beginning of any offering period, the administrator may alter the maximum number of shares that may be purchased by any participant during the offering period or specify a maximum aggregate number of shares that may be purchased by all participants in the offering period. If insufficient shares remain available under the plan to permit all participants to purchase the number of shares to which they would otherwise be entitled, the administrator will make a pro rata allocation of the available shares. Any amounts withheld from participants' compensation in excess of the amounts used to purchase shares will be refunded, without interest.

In the event of a change in control, an acquiring or successor corporation may assume our rights and obligations under the 2007 Purchase Plan. If the acquiring or successor corporation does not assume such rights and obligations, then the purchase date of the offering periods then in progress will be accelerated to a date prior to the change in control.
