Company Background	1. Company Background
	OCZ Technology Group, Inc., a Delaware corporation (“OCZ”) was formed in 2002. OCZ is a leader in the design, manufacturing, and distribution of high performance and reliable Solid-State Drives (“SSDs”) and premium computer components. OCZ has built on its expertise in high-speed memory to become a leader in the enterprise and client SSD markets, a technology that competes with traditional rotating magnetic hard disk drives (“HDDs”). SSDs are faster, more reliable, generate less heat and use significantly less power than the HDDs used in the majority of computers today. OCZ designs and manufactures SSDs in a variety of form factors and interfaces including SATA, SAS, PCIe, as well as flash caching and virtualization software to provide a total solution for enterprise clients. In addition to SSD technology, OCZ also offers enterprise-class power management products. During the fiscal year ended February 29, 2012, OCZ completed three strategic acquisitions including Indilinx Co., Ltd, (a Korean company) in March 2011, certain assets and technology including a research and development design team from PLX Technology Inc. (with principal operations in the United Kingdom) in October 2011 and Sanrad Inc. (with principal operations in Israel) in January 2012.
	The Company’s audited consolidated financial statements have been prepared on a going concern basis, which assumes continuity of operations and realization of assets and satisfaction of liabilities in the ordinary course of business. The Company has incurred recurring operating losses and negative cash flows from operating activities since inception through February 28, 2013. In addition, the Company had an accumulated deficit of $310.7 million as of February 28, 2013. Through February 28, 2013, the Company has not generated sufficient cash from operations and has relied primarily on the proceeds from equity offerings and debt financing such as increased trade terms from vendors and credit facilities to finance its operations. Compliance by the Company with the provisions of its existing credit agreements, its ability to obtain alternative or additional financing when needed, and its ability to generate profitable operations are important parts of its ability to continue as a going concern.
	The Company will be required to secure one or more additional financings to fund its near-term operations. Raising additional capital involves risks and uncertainties, and alternative or additional funding may not be available to the Company on acceptable terms, on a timely basis, or at all. The Company believes that a number of factors will contribute to its financing risks, including its history of operating losses, its accounting restatement and its inability to use simplified securities registration forms due to the delays in filing its recent annual and quarterly reports with the SEC. To the extent that the Company raises additional capital through the sale of equity, convertible debt securities or other securities linked to our equity, the ownership interest of existing stockholders will be diluted, and the terms may include liquidation or other preferences that adversely affect the rights of existing stockholders. Debt financing, if available, would result in increased fixed payment obligations and may involve agreements that include covenants limiting or restricting the Company’s ability to take specific actions such as incurring debt, making capital expenditures or declaring dividends.
	The Company’s credit agreements and other loan documents include material debt service costs, operating ratios that the Company must meet and other financial covenants such as the raising of additional capital and the delivery of past due audited financial statements to the lenders. In order to fund debt service costs and operate profitably, the Company may have to curtail its operations to reduce costs. Doing so may be disruptive to the business and affect the Company’s ability to compete effectively and operate efficiently. Further, the Company is currently not in compliance with certain of its lending covenants, including certain minimum operating ratios, and there can be no assurances that the Company will be able to obtain a waiver for non-compliance and comply with these covenants in the future. If the Company does not obtain a waiver and maintain future compliance with the covenants in its credit agreements or if the Company is not able to generate sufficient cash from operations to make the principal and interest payments under the agreements when due, the lenders could declare a default. Any default under its credit agreements will allow the lenders under these agreements the option to demand repayment of the indebtedness outstanding under the applicable credit agreements and to foreclose on our assets that have been pledged as collateral under the applicable agreement.
	If lenders were to exercise their rights to accelerate the indebtedness outstanding, the Company would be required to secure additional sources of funding which may have a material adverse effect on the Company’s business, liquidity and financial condition. This and other factors included above raise substantial doubt about the Company’s ability to continue as a going concern. Management plans regarding these going concern uncertainties include various initiatives, including continued shifts to more profitable, higher-margin enterprise products, the introduction of competitive new products as complete systems solutions, continued reduction of costs and the exploration of potential strategic alternatives for the business or segments of the business. The Company’s audited consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

	On October 11, 2012, the Company filed a Form 12b-25, Notification of Late Filing, with the Securities and Exchange Commission with respect to its Quarterly Report on Form 10-Q for the quarter ended August 31, 2012, due to the time required to conduct an internal assessment of the Company’s accounting for customer incentive programs. In September 2012, the Audit Committee of the Board of Directors commenced an internal investigation principally related to the classification of certain customer marketing costs, the timing of revenue recognition and the level of reserves for product returns. In October 2012, the Audit Committee engaged a legal firm to lead an independent investigation into certain accounting practices. In turn, the independent legal firm engaged a forensic accounting firm to provide consulting services in connection with the independent investigation, and during the investigation, special counsel was hired to investigate compliance with the Foreign Corrupt Practices Act (“FCPA”). The scope of the independent investigation was determined by the Audit Committee and its legal and accounting advisors. On January 10, 2013, the Company filed a Form 12b-25, Notification of Late Filing, with the Securities and Exchange Commission with respect to its Quarterly Report on Form 10-Q for the quarter ended November 30, 2012, due to the additional time required to complete the internal assessment of the Company’s accounting for customer incentive programs. As a result of the internal assessment and the evaluation of the substance of information obtained during the independent investigation (collectively the “Investigation”), as discussed further below, the Company concluded that errors had been made in its previously-issued consolidated financial statements. Accordingly, based upon extensive reviews of forensic materials, interviews and analyses of subsequent accounting records, adjustments were made, and the Company’s consolidated financial statements as of and for the fiscal years ended February 28/29, 2012, and 2011, as well as the nine interim quarterly periods ended May 31, 2012 are being restated. These adjustments are described below:
		a)	The Company enters into programs with many of its customers, which allow them to receive a credit equal to one or more of the following: 1) reimbursement of certain marketing costs, such as ad placements in periodicals, select email distributions and internet-based advertising (“Market Development Funds”), that are negotiated individually or limited by a percentage of customer purchases of the Company’s products, 2) rebates, including performance-based incentives and consumer rebates, and 3) price protection credits if the sale price of products decreases in a future period, subject to limitations (collectively, customer incentive program (“CIP”) or “CIP Credits”). Accruals for these CIP Credits were historically recorded at the time of sale or time of commitment based on negotiated terms, historical experience and inventory levels of the Company’s customers. Market Development Funds are classified as an operating expense if they have both an identifiable benefit to the Company and an established fair value; otherwise, they are classified as a reduction of our revenue. In the second and third quarters of fiscal 2013, the Company received a significant increase in the number of requests from its customers for CIP Credits. In connection with the results of the Investigation, management and the Audit Committee concluded that many of these CIP Credits were the result of the circumvention of established internal controls and were not accounted for correctly. The Company identified the following issues in recording CIP Credits:
		i.	Due to management and personnel turnover and a lack of documentary evidence to establish the nature of certain CIP Credits recorded beginning in the third quarter of fiscal 2012, the Company was not able to determine the financial periods in which those CIP Credits were originally committed to customers. Therefore, for each customer, beginning with the third quarter of fiscal 2012 through the third quarter of fiscal 2013, the Company allocated these CIP Credits ratably over the periods in which gross revenue was generated.
		ii.	Historically, the Company had included in operating expense Market Development Funds reimbursed by it if such costs both had an identifiable benefit and for which the Company was able to determine fair value. However, in connection with the Investigation, the Company determined that in substance, a portion of the credits recorded as Market Development Funds represented incentive rebates, volume discounts and price protection adjustments, which had been incorrectly documented as marketing commitments to customers as a result of the circumvention of the established internal controls as discussed in (a) above, and which should have been recorded as a reduction of revenue. Consequently, as part of the restatements, the Company has reclassified all such credits from operating expenses to a reduction of revenue ratably over the period in which gross revenue was generated.
	Corrections and adjustments for these errors and irregularities accounted for reductions of revenue of $5.6 million, $17.5 million and $15.1 million in the years ended February 28/29, 2011 and 2012 and the first quarter of fiscal 2013, respectively, and reductions of operating expenses of $5.6 million, $12.2 million and $8.0 million in the years ended February 28/29, 2011 and 2012 and the first quarter of fiscal 2013, respectively.
		b)	The Company’s revenue recognition policy provides for revenue to be recognized upon shipment, provided certain criteria are met. In connection with the results of the Investigation, the Company determined that there were some sales that did not meet the criteria for revenue recognition in the period in which the sale had originally been recognized. These sales were primarily related to distributor customers who either were offered return rights, were not able to pay the Company until they were able to re-sell to their end customers or who required the Company to perform post-delivery obligations. Consequently, since the Company had originally recorded these sales as revenue upon shipment, it recorded adjustments to defer these sales, net of the corresponding cost of these sales as a deferred liability until the criteria for revenue recognition was met. This deferral of revenue accounted for a reduction of revenue of $12.6 million and $12.2 million in fiscal 2012 and the first quarter of fiscal 2013, respectively, and a reduction of cost of revenue of $9.8 million and $9.6 million in fiscal 2012 and the first quarter of fiscal 2013, respectively.
		c)	The Company received a significant increase in product returns from its customers beginning in the second quarter of fiscal 2013. In connection with the results of the Investigation, management and the Audit Committee concluded that due to the amount and product mix of inventory the Company’s customers were holding, these sales had not met the criteria for revenue recognition as the fees were considered to not be fixed and determinable at the time of shipment. Consequently, as these sales had been accounted for as revenue in financial periods beginning in the third quarter of fiscal 2012 through the first quarter of fiscal 2013, the Company reversed the revenue in the period in which the sales had originally been recognized. These reversals accounted for a reduction of revenue and accounts receivable of $6.5 million and $5.3 million in fiscal 2012 and the first quarter of fiscal 2013, respectively, and a reduction in cost of revenue and increase in inventory of $4.9 million and $3.7 million in fiscal 2012 and the first quarter of fiscal 2013, respectively.
		d)	In connection with the Investigation, the Company re-evaluated its original estimate of the allowance for product it expected to be returned, and consequently, increased its allowance for sales returns. This increased estimate for sales returns accounted for reductions of revenue and accounts receivable of $0.5 million, $8.9 million and $3.1 million in fiscal 2011, 2012 and the first quarter of fiscal 2013, respectively, and reductions in cost of revenue and increases in inventory of $0.4 million, $7.1 million and $2.2 million in the same periods, respectively.
		e)	After recording the adjustments to revenue described above, the cost of revenue exceeded the net revenue recognized for certain sales transactions. In accordance with ASC 330-10-35-13, the Company evaluated whether this negative gross margin might indicate an impairment of existing inventory at each prior financial period. This analysis resulted in increases to cost of revenue and the corresponding inventory reserves of $3.7 million and $6.1 million in fiscal 2012 and the first quarter of fiscal 2013, respectively.
		f)	Also in connection with the Investigation, the Company identified a $1.9 million sale to a customer, which was recorded as revenue in the third and fourth quarters of fiscal 2012, that did not meet the criteria for revenue recognition at the time of the original shipment since the Company did not have sufficient evidence of a persuasive arrangement and collectability was not reasonably assured. In connection with the $1.9 million original sale, $1.2 million and $0.7 million was subsequently recorded as a bad debt expense and an allowance for doubtful accounts in the fourth quarter of fiscal 2012. As part of the restatements, in the third quarter of 2012, the original $1.9 million sale was reversed, and in the fourth quarter of fiscal 2012, the related $1.2 million bad debt expense was reversed.
	In addition to the above errors, in the course of the Company’s restatement work, it identified additional errors that were corrected, including:
		a)	Certain manufacturing and freight costs that had been expensed should have been capitalized in inventory. In connection with the restatements, the Company reduced operating expenses of $6.0 million, $9.3 million and $3.0 million for the years ended February 28/29, 2011 and 2012 and for the three months ended May 31, 2012, respectively. Cost of revenue was increased by $5.8 million, $8.4 million and $2.7 million, and inventory was increased by $0.2 million, $0.9 million and $1.1 million, for the same periods, respectively.
		b)	Reserves for excess and obsolete inventory had incorrectly excluded reserves to reduce the carrying value of certain items that had been returned from customers. Further, we had not recognized costs on a timely basis related to inventories used for internal development purposes. Therefore, in connection with the restatements, the Company increased cost of revenue by $0.3 million, $16.6 million and $(1.6) million for the year ended February 28/29, 2011 and 2012 and the three months ended May 31, 2012, respectively. In addition, research and development expenses were increased by $0.7 million, $2.9 million and $0.1 million for the years ended February 28/29, 2011 and 2012 and the three months ended May 31, 2012, and inventory was reduced by $0.9 million, $24.1 million and $28.8 million as of the end of the same periods, respectively.
		c)	Errors were noted in the Company’s calculation of accruals for estimated future warranty and repair obligations. The correction of these errors resulted in higher cost of revenue of $0.1 million, $2.9 million and $0.5 million for the years ended February 28/29, 2011 and 2012 and for the three months ended May 31, 2012, respectively. Further, revenue reductions of $1.9 million, $0.4 million and $0.3 million were recorded for the same periods, respectively, with corresponding adjustments to accrued warranty liabilities and net inventories.
		d)	Revenue and related cost of revenue were incorrectly recognized upon shipment for certain sales transactions that were determined to be in-transit at the balance sheet date and for which title had not transferred to the customer. Revenue of $1.5 million, $7.0 million and $0.8 million was reversed for the years ended February 28/29, 2011 and 2012 and for the three months ended May 31, 2012, respectively, and cost of revenue of $1.2 million, $5.2 million and $(0.6) million were reduced (increased) for the same periods, respectively.
		e)	Certain costs of revenue were incorrectly classified as operating expenses, which caused our gross margins to be overstated. In connection with the restatement, we reclassified $4.2 million and $6.6 million from research and development expenses to cost of revenue for the fiscal year ended February 29, 2012 and for the three months ended May 31, 2012, respectively.
	Further, as a result of the above entries, we reassessed the carrying amount of goodwill and determined that an impairment should be recorded as of February 29, 2012. We originally performed our annual impairment test of goodwill as of February 29, 2012, and determined that no impairment existed. However, based upon the errors and related control weaknesses discussed above, and the continued deterioration in its operating results and revenue forecasts, the Company reperformed the impairment test at February 29, 2012, and concluded that an impairment charge of $61.9 million should be recorded in the three months ended February 29, 2012, representing a write-off of the entire amount of previously-recorded goodwill. Also as a result of the above entries, the Company’s income tax provision was adjusted to reflect the tax impact of the restatement adjustments noted above and to record the appropriate tax provision for each jurisdiction in which the Company operates.
	All notes to the consolidated financial statements affected by the restatements have been labeled as restated.

-1	“Revenue Recognition” represents various transactions that were recognized prior to meeting the revenue recognition criteria. Adjustments were recorded to reverse the original revenue recorded, defer the original revenue recorded or provide reserves against net revenue for future product returns. Also included are adjustments to recognize the reversal of the product cost, which are recorded as reductions of cost of revenue and increases to either inventory or deferred product cost.
-2	“CIP Credits” represent Market Development Funds, rebates and price protection credits. These adjustments were made to record CIP Credits in the correct accounting period and to classify them correctly in our consolidated statements of operations.
-3	“Manufacturing and Freight” represents manufacturing and freight costs that should have been capitalized as a component of product costs but were incorrectly expensed as incurred. Adjustments were made to reduce operating expenses and increase inventory (for products on hand) and cost of revenue (for products shipped).
-4	“Goodwill and Intangibles” represents a write-off of goodwill related to prior acquisitions due to a revision to our estimated enterprise value and a revision to the estimated value of certain intangible assets.
-5	“Inventory Reserves” represents adjustments to reduce the carrying value of certain inventory items that had generally either had been returned from customers or were being used for internal development purposes.
-6	“Accruals” represents accruals for future costs to be incurred primarily for warranty and repair obligations.
-7	“Income Taxes” represents adjustments to reflect the tax impact of the restatement adjustments noted above and to record the appropriate tax provision for each jurisdiction in which the Company operates.
-8	“Reclassifications” represents the impact of reclassifications on prior period financial statements in order to conform to the current year presentation.
-9	Includes changes in allowance for bad debts.
-10	Includes the expensing of certain prepaid assets to research and development of $2.1 million.
-11	Includes the expensing of certain prepaid assets to research and development of $2.1 million and changes in allowances for bad debts of $78,000.

Summary of Significant Accounting Policies	12 Months Ended
	Feb. 28, 2013
Summary of Significant Accounting Policies	3. Summary of Significant Accounting Policies
	Basis of preparation
	The accompanying consolidated financial statements include the accounts of OCZ and its wholly-owned subsidiaries in Canada, Israel, Korea and the United Kingdom. All intercompany transactions and balances have been eliminated. OCZ’s fiscal year begins on March 1 and ends on February 28 or 29. All material intercompany balances and transactions have been eliminated. The significant accounting policies used in the preparation of the financial statements are summarized below.
	Reclassifications
	Certain prior year balances have been reclassified to conform to the current year presentation.
	Use of estimates
	The preparation of these financial statements in conformity with generally accepted accounting principles (“GAAP’’) in the United States of America requires management to make estimates, assumptions and exercise judgment that affect the reported amounts of assets, liabilities, revenues and expenses and related note disclosures. The level of uncertainty in estimates and assumptions increases with the length of time until the underlying transactions are completed. Actual results may differ from those estimates.
	On an ongoing basis, the Company evaluates its estimates, including, among others, those related to bad debts and other related allowances, inventories and related reserves, income taxes, warranty obligations, fair value of common stock warrant liability stock-based compensation, business combinations, legal contingencies, realizability of goodwill and the assessment of recoverability of long-lived assets. The Company bases its estimates on historical experience and on other assumptions that it believes are reasonable under the circumstances, the results of which form the basis for its judgments about the carrying values of assets and liabilities when those values are not readily apparent from other sources. However, future results will differ from these estimates under different assumptions and conditions.
	Cash equivalents
	Cash equivalents are considered highly liquid investments purchased with an original maturity of three months or less.
	Restricted Cash
	Restricted cash represents amounts designated for uses other than current operations. The Company periodically makes deposits of restricted cash for irrevocable letters of credit related to vendor obligations, and the lease of the Company’s corporate headquarters in San Jose, California.
	Concentration of credit risks
	Financial instruments which potentially subject the Company to concentrations of credit risk include our cash and cash equivalents and uninsured accounts receivable.
	During the periods presented herein, the Company had deposits in banks in excess of the Federal Deposit Insurance Corporation insurance limit. The Company has not experienced any losses of such deposits to date. The Company is exposed to credit risk in the event of a default by the financial institutions holding our cash and cash equivalents to the extent recorded on the balance sheet. The Company is also subject to credit risk from our accounts receivable related to our product sales which are stated at the amount which management expects to collect. The Company’s trade accounts receivable do not bear interest. Customer creditworthiness is monitored and collateral is not required. The Company maintains credit insurance on the majority of its accounts receivable, and it has not experienced significant accounts receivable losses to date. It maintains a valuation allowance for doubtful accounts, estimated sales returns and CIP Credits. Management considers the following factors when determining the collectability of specific customer accounts: customer credit worthiness, transaction history, current economic trends and customer insurability. See Note 7.
	Inventories
	Inventories are stated at the lower of cost or market using the average cost method. OCZ establishes provisions for excess and obsolete inventories to reduce the carrying values of such inventories to their estimated net realizable value after evaluation of historical sales, future demand, market conditions and expected product life cycles. Such provisions are included in “Cost of revenue” in the Consolidated Statements of Operations.
	Consignment product shipped to some of the Company’s resellers is included in finished goods inventory. Inventory also includes estimated product to be returned to the Company as part of its allowance for sales returns. The Company includes consignment inventory and inventory expected to be returned within the category of inventory on its Consolidated Balance Sheets. See Note 7.
	Property and equipment
	Property and equipment is recorded at cost. The cost of maintenance and repairs is expensed as incurred. Depreciation and amortization is computed using the straight line method over the estimated useful lives of the assets as follows:
	Vehicles		3 years
	Furniture and fixtures		3 — 5 years
	Equipment		3 — 5 years
	Leasehold improvements		Shorter of remaining lease term or estimated useful life.
	Business Acquisitions
	The Company’s consolidated financial statements include the operations of acquired businesses after the completion of the acquisitions. The Company accounts for acquired businesses using the acquisition method of accounting. The acquisition method of accounting for acquired businesses requires, among other things, that most assets acquired and liabilities assumed be recognized at their estimated fair values as of the acquisition date, with limited exceptions, and that the fair value of acquired intangible assets including in-process research and development, or IPR&D, be recorded on the balance sheet. Also, transaction costs are expensed as incurred. Any excess of the acquisition consideration over the assigned values of the net assets acquired is recorded as goodwill.
	Goodwill
	Goodwill represents the excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed. The Company has determined that it operates in a single segment and has a single reporting unit associated with the design, development, manufacture, sale and support of high performance and reliable Solid-State Drives (“SSDs’’) and premium computer components. In September 2011, the FASB amended its guidance to simplify testing goodwill for impairment, allowing an entity to first assess qualitative factors to determine whether it is necessary to perform a two-step quantitative goodwill impairment test. If an entity determines as a result of the qualitative assessment that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the quantitative impairment test is required. Otherwise, no further testing is required. The performance of the quantitative impairment test involves a two-step process. The first step of the impairment test involves comparing the fair values of the applicable reporting unit with its aggregate carrying value, including goodwill. The Company generally determines the fair value of its reporting unit using the income approach methodology of valuation that includes the discounted cash flow method, the market approach that includes a comparative analysis of a peer group of publicly traded companies, as well as other generally accepted valuation methodologies. If the carrying amount of the reporting unit exceeds the reporting unit’s fair value, the Company performs the second step of the quantitative impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill.
	The Company performs goodwill impairment testing at the reporting unit level at least annually in the fourth fiscal quarter or more often if events or changes in circumstances indicate the carrying value may not be recoverable.
	Impairment of long-lived assets
	Long-lived assets consist of property and equipment and purchased intangible assets. Purchased intangible assets from business combinations include trademarks and trade names, customer relationships, the amortization of which is charged to sales and marketing expenses, and core and developed technology, the amortization of which is charged to cost of revenue.
	The Company tests long-lived assets or asset groups for recoverability when events or changes in circumstances indicate that their carrying amounts may not be recoverable. Circumstances which could trigger a review include, but are not limited to: significant decreases in the market price of the asset; significant adverse changes in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of the asset; current period cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and current expectation that the asset will more likely than not be sold or disposed of before the end of its estimated useful life.
	Recoverability is assessed based on the carrying amounts of the asset and its fair value which is generally determined as the sum of the undiscounted cash flows expected to result from the use and the eventual disposal of the asset, as well as specific appraisals in certain instances. An impairment loss is recognized when the carrying amount is not recoverable and exceeds fair value.
	Restructuring charges
	Restructuring charges include costs related to employee termination benefits and long-lived assets impaired or abandoned. The determination of when we accrue for employee termination benefits depends on whether the termination benefits are provided under a one-time benefit arrangement or under an on-going benefit arrangement. For restructuring charges recorded as an on-going benefit arrangement, a liability for post-employment benefits is recorded when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated. For restructuring charges recorded as a one-time benefit arrangement, we recognize a liability for employee termination benefits when a plan of termination, approved by management and establishing the terms of the benefit arrangement, has been communicated to employees. The timing of the recognition of one-time employee termination benefits is dependent upon the period of time the employees are required to render service after communication. If employees are not required to render service in order to receive the termination benefits or if employees will not be retained to render service beyond the minimum legal notification period, a liability for the termination benefits is recognized at the communication date. In instances where employees will be retained to render service beyond the minimum legal notification period, the liability for employee termination benefits is measured initially at the communication date based on the fair value of the liability as of the termination date and is recognized ratably over the future service period. We continually evaluate the adequacy of the remaining liabilities under our restructuring initiatives.
	Although we believe that these estimates accurately reflect the costs of our restructuring plans, actual results may differ, thereby requiring us to record additional provisions or reverse a portion of such provisions.
	Income taxes
	The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse and for operating losses and tax credit carry forwards. The Company estimates its provision for income taxes and amounts ultimately payable or recoverable in numerous tax jurisdictions around the world. Estimates involve interpretations of regulations and are inherently complex. Resolution of income tax treatments in individual jurisdictions may not be known for many years after completion of any fiscal year. The Company is required to evaluate the realizability of its deferred tax assets on an ongoing basis to determine whether there is a need for a valuation allowance with respect to such deferred tax assets. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. Significant management judgment is required in determining any valuation allowance recorded against deferred tax assets. In evaluating the ability to recover deferred tax assets, the Company considers available positive and negative evidence giving greater weight to its recent cumulative losses and our ability to carryback losses against prior taxable income and, commensurate with objective verifiability, the forecast of future taxable income including the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies.
	The Company recognizes and measures uncertain tax positions taken or expected to be taken in a tax return if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such positions are then measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The Company adjusts these reserves in light of changing facts and circumstances, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate, as well as the related net interest. The Company recognizes interest and penalties related to unrecognized tax benefits within the other income (expense) line in the consolidated statements of operations. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheets.
	The Company files annual income tax returns in multiple taxing jurisdictions around the world. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves, as well as the related interest, in light of changing facts and circumstances. Settlement of any particular position could require the use of cash.
	Fair value of financial instruments
	OCZ’s financial instruments consist primarily of cash equivalents, accounts receivable, accounts payable, accrued liabilities and loans payable. The carrying value of these financial instruments approximates fair value as they are short-term to maturity. Derivative liabilities consist of common stock warrants and are classified as Level 3 liabilities under the fair value hierarchy.
	The applicable accounting guidance establishes a framework for measuring fair value and expands required disclosure about the fair value measurements of assets and liabilities. This guidance requires the Company to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a nonrecurring basis in periods subsequent to initial measurement, in a three-tier fair value hierarchy as described below.
	The guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
	Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The guidance describes three levels of inputs that may be used to measure fair value:
		•		Level 1 — Observable inputs that reflect quoted prices for identical assets or liabilities in active markets.
		•		Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		•		Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	The Company uses the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. During fiscal years 2013 and 2012, there were no nonrecurring fair value measurements of assets subsequent to initial recognition.
	Revenue recognition
	The Company records product revenue net of allowances for sales returns and CIP Credits, as described below. Revenue is recognized when the following criteria have been met:
		•		There is persuasive evidence of an arrangement, generally evidenced by customer purchase orders and/or contracts;
		•		Delivery has occurred, generally upon product shipment by a common carrier when the risk of loss has passed, or the customer has waived its rights to such criteria;
		•		The terms are fixed and determinable and not subject to refund or adjustment; and
		•		Collection is reasonably assured.
	Probability of collection is assessed for each customer as it is subjected to a credit review process that evaluates the customer’s financial position, ability to pay, and the potential coverage by the Company’s credit insurer. If it is determined from the outset of an arrangement that collection is not reasonably assured, the customer generally is required to pay cash in advance of shipment. The Company also purchases credit insurance for the majority of its accounts receivable. If collectability is not considered reasonably assured from the outset of an arrangement, and the customer has not been required to pay cash in advance of shipment, the Company does not recognize revenue until collection occurs.
	The Company records allowances against revenue for various credits under customer programs:
		•		Product Returns – The Company grants limited rights to return product. Return rights vary by customer, and include stock rotation rights limited to a percentage approved by management and, in certain circumstances, the right to return defective products for credit under our warranty policy. Estimates of expected future sales returns are recognized at the time of sale based on analyses of historical return trends by customer and by product, inventories owned by and located at distributors and retailers, current customer demand, current operating conditions, product failure rates and other relevant customer and product information. Products returned are generally available for resale. Consequently, when the related product revenue is recognized, a sales return reserve is recorded along with a corresponding reduction of revenue and cost of revenue and reinstatement of the related inventory.
		•		Customer Marketing Programs – The Company issues credits for Market Development Funds under a variety of customer marketing programs with many of its distribution and retail customers, and with certain indirect partners. Allowances for Market Development Funds are made against revenue if the programs either do not have an identifiable benefit to the Company or for which the Company is unable to determine fair value. Accruals for these Marketing Development Funds are recorded at the time of sale, or time of commitment, based on negotiated terms. We provide for these programs as a reduction to revenue when the related product revenue is recorded.
		•		Rebates – Rebate programs include performance-based incentives and consumer rebates. Allowances for rebates are made based on negotiated terms, consideration of historical experience, anticipated volume of future purchases, and inventory levels of our customers.
		•		Price Protection – Certain customer agreements contain terms allowing price protection credits to be issued in the event of a subsequent price reduction, subject to limitations. An allowance for estimated price protection credits to be granted is made when the related product revenue is recorded.
	Significant management judgment must be used in estimating allowances under these programs in any accounting period. The Company regularly evaluates the adequacy of its accruals for sales returns and CIP Credits. Future market conditions and product transitions may require the Company to take action to increase such programs. In addition, when the variables used to estimate these costs change, or if actual costs differ significantly from the estimates, the Company would be required to record incremental reductions to revenue. If, at any future time, the Company becomes unable to reasonably estimate these costs, recognition of revenue is deferred until products are sold to end-users, which would adversely impact revenue recognized in the period of transition.
	Research and development costs
	Research and development costs are expensed as incurred.
Shipping and handling
For the fiscal years ended February 2013, 2012 and 2011, shipping and handling costs were $4.8 million, $4.7 million and $2.9 million, respectively, and are reflected in sales and marketing expense in the Consolidated Statement of Operations.
Advertising
The Company engages in a variety of methods of direct advertising and marketing media which generally includes ad placement in periodicals and internet-based advertising. All of the Company’s direct advertising costs are recorded as a sales and marketing expense as incurred. Advertising costs in the fiscal years ended February 2013, 2012 and 2011 were $3.3 million, $2.3 million and $3.1 million, respectively.
Currency translation
The majority of the Company’s sales are invoiced in United States Dollars (“USD”). Invoices in Euro and British Pound were insignificant during the fiscal years ended February 2013, 2012 and 2011.
The functional currency of the Company’s Canadian, Korean and UK entities is their local currency. All of the Company’s other foreign operations use the USD as their functional currency. When the local currency is the functional currency, gains and losses from translation of these foreign currency financial statements into USD are recorded as a separate component of other comprehensive income (loss) in stockholders’ equity. For subsidiary and branch operations where the functional currency is the USD, gains and losses resulting from remeasurement of foreign currency denominated balances into USD are included in other income (expense), net. Foreign currency transaction gains and (losses) for the fiscal years ended February 2013, 2012 and 2011 were $0.5 million, $0.2 million and $41,000, respectively and were included in other income (expense), net in the accompanying Consolidated Statements of Operations.
Product warranties
The Company generally warrants its products for a period of three to five years. Concurrent with the period when product revenue is recognized, a provision is recorded for the estimated warranty obligation to provide for the replacement of products or account credits for products that are found to be faulty within the warranty period. The obligation is adjusted periodically based on historical and anticipated experience.
Stock-based compensation
Stock-based compensation is measured based on the grant-date fair value. Fair value is estimated using the Black-Scholes model. Compensation expense for stock options is recognized on the straight-line basis over the period earned and vested. Restricted stock grants are measured based on the fair market value of the underlying stock on the date of grant and compensation expense for restricted stock grants is recognized on the straight-line basis over the requisite service period. Non-vested stock options and restricted stock grants are included in the diluted shares outstanding calculation when their effect is dilutive.
The amount of compensation expense recognized using the Black-Scholes model requires the Company to exercise judgment and make assumptions relating to the factors that determine the fair value of stock option grants. The fair value calculated by this model is a function of several factors, including the grant price, the expected future volatility and the expected term of the option and the risk-free interest rate of return over the estimated option period. The expected term and expected future volatility of the options require judgment. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those stock options expected to vest. The Company estimates the forfeiture rate based on historical experience and to the extent the actual forfeiture rate is different from the estimate, share-based compensation expense is adjusted accordingly.
Common stock warrant liability
The Company accounts for certain warrants to purchase shares of common stock which are subject to certain anti-dilution adjustments which require them to be classified as derivatives. Accordingly, upon issuance, the fair value of the common stock warrants is recorded as a common stock warrant liability with a corresponding reduction of additional paid-in capital or as a discount to the related debt instrument for which the warrants were issued. The common stock warrants are subject to remeasurement to fair value at each balance sheet date, and any fair value adjustments are recognized and included in “Revaluation to fair value of common stock warrants” in the Consolidated Statements of Operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the common stock warrants. At that time of exercise or expiration, the common stock warrant liability will be adjusted to fair value with the fair value change reflected in the Consolidated Statements of Operations and the remaining final fair value, if any, will be reclassified to additional paid-in capital.
Net loss per share
Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed giving effect to all potential dilutive common stock, including stock options, restricted stock units and common stock warrants outstanding. Diluted loss per share was based only on the weighted-average number of shares outstanding during that period as the inclusion of any common stock equivalents would have been anti-dilutive.
A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per share is as follows (in thousands):
		Years Ended February 28/29,
		2013			2012			2011
					Restated			Restated
Numerator:
Net loss used in computing basic and diluted net loss per share		$	(125,786	)	$	(123,452	)	$	(33,186	)
Denominator:
Weighted-average shares used in computing basic net loss per share			67,722			50,855			28,689
Add potentially dilutive securities			—			—			—
Weighted-average shares used in computing diluted net loss per share			67,722			50,855			28,689
Net loss per share –basic and diluted		$	(1.86	)	$	(2.43	)	$	(1.16	)
The following table sets forth the weighted-average potentially dilutive securities excluded from the computation in the table above because their effect would have been anti-dilutive:
		Years Ended February 28/29,
		2013			2012			2011
Stock options			8,259,209			5,935,605			4,025,056
Restricted stock units			803,591			—			—
Common stock warrants			3,457,521			3,552,521			4,389,604
Total potentially dilutive securities			12,520,321			9,488,126			8,414,660
All outstanding options, restricted stock units and common stock warrants are potentially dilutive securities. However, since the Company incurred net losses during each of the fiscal periods presented, all potentially dilutive securities would have been anti-dilutive and were excluded from the computation of diluted shares. Accordingly, shares used to calculate basic and diluted net loss per share were the same in each period reported.

New Accounting Pronouncements	4. New Accounting Pronouncements
	Fair Value
	In May 2011, updated authoritative guidance to amend existing requirements for fair value measurements and disclosures was issued. The guidance expands the disclosure requirements around fair value measurements categorized in Level 3 of the fair value hierarchy and requires disclosure of the level in the fair value hierarchy of items that are not measured at fair value but whose fair value must be disclosed. It also clarifies and expands upon existing requirements for fair value measurements of financial assets and liabilities as well as instruments classified in stockholders’ equity. The guidance was effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and was applied prospectively. This new guidance impacts how we report on fair value measurements only, and had no effect on our results of operations, financial position or liquidity upon our adoption on March 1, 2012.
	Comprehensive Income
	In June 2011, authoritative guidance that addresses the presentation of comprehensive income in interim and annual reporting of financial statements was issued. The standard eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. Such changes in stockholders’ equity will be required to be disclosed in either a single continuous statement of comprehensive income or in two separate but consecutive statements. We have adopted this guidance effective with the first quarter of fiscal 2013. Other than the change in presentation, such adoption did not have a material impact on our consolidated financial statements.
	In February 2013, the FASB issued revised guidance on “Comprehensive Income: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” The revised guidance does not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the revised guidance requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The revised guidance is effective prospectively for reporting periods beginning after December 15, 2012 for public entities. The revised guidance will not have a material effect on the Company’s financial position, results of operations or liquidity upon our adoption on March 1, 2013.
	Offsetting Assets and Liabilities
	In December 2011, the FASB issued additional guidance regarding “Disclosures about Offsetting Assets and Liabilities”. The additional guidance requires an entity to disclose information about offsetting and related arrangements on its financial position. This includes the effect or potential effect of rights of offset associated with an entity’s recognized assets and recognized liabilities and require improved information about financial instruments and derivative instruments that are either (1) offset in accordance with the additional guidance or (2) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in accordance with the additional guidance. The amendments are effective for annual reporting periods beginning on or after January 1, 2013 and retrospective disclosure is required for all comparative periods presented. No early adoption is permitted. Currently, the Company does not enter into any right of offset arrangements and expects implementation of this additional guidance to have little or no impact.

Acquisitions

Acquisitions	5. Acquisitions
	Indilinx
	On March 25, 2011, OCZ completed the acquisition of 100% of the equity interests of Indilinx Co., Ltd., (“Indilinx”) a privately-held company organized under the laws of the Republic of Korea. Indilinx’s products and solutions are comprised of advanced controllers, SSD reference designs, and software, which enable the rapid development and deployment of high performance solid state drives. The technology powers a wide range of storage solutions from cost-sensitive consumer devices to performance-optimized systems demanded by mission-critical enterprise applications. At the time of acquisition, Indilinx’s products included the Barefoot SSD controller which meets the demanding performance requirements of PC and Server applications and also helps facilitate the use of new high performance NAND flash memory, and the Amigos SSD controller which is ideally suited for embedded systems, mobile PCs, and other applications which require the speed, reliability, and power benefits of SSDs in a smaller form factor and at lower price points.
	The acquisition of Indilinx is expected to expand OCZ’s presence in the embedded, hybrid storage, and industrial markets. The Indilinx acquisition is also intended to broaden OCZ’s intellectual property resulting from Indilinx’s portfolio of 26 patents and patent applications. In addition, the acquisition provided an assembled workforce, the implicit value of future cost savings as a result of combining entities, and is expected to provide OCZ with future unidentified new products and technologies. These opportunities were significant factors to the establishment of the acquisition price, which exceeded the fair value of Indilinx’s net assets acquired, resulting in goodwill of $36.9 million. See Note 8. Goodwill.
	The total acquisition consideration of $32.8 million consisted of (i) 4.2 million shares of OCZ common stock with a total fair value of $32.2 million, based on the price of OCZ common stock at the time of close, and (ii) $0.6 million of cash paid to the holders of Indilinx vested and unvested stock options as of the close of the transaction. The Company also incurred a total of $1.7 million of transaction costs which were primarily comprised of legal, accounting and valuation expenses in the quarter ended May 31, 2011. These transaction costs are classified as “Acquisition-related charges” on the Consolidated Statement of Operations for the year ended February 29, 2012.
	The results of operations of Indilinx are included in OCZ’s Consolidated Statements of Operations from March 25, 2011, the date of acquisition. The following table summarizes fair value of the assets acquired and the liabilities assumed at the date of acquisition (in thousands):
	Cash acquired		$	554
	Other current assets			170
	Fixed assets			431
	Other tangible assets acquired			216
	Intangible assets
	Existing technology			96
	In-process technology			1,974
	Customer lists and related relationships			75
	Trademarks and trade names			125
	Goodwill			36,858
	Total assets acquired			40,499
	Loans payable			(4,923	)
	Accounts payable			(519	)
	Other accrued liabilities			(1,785	)
	Deferred tax liabilities			(499	)
	Total acquisition consideration		$	32,773
	Indication of fair value of the intangible assets acquired in connection with the Indilinx acquisition were determined using the income approach. The Company used an overall discount rate of approximately 15% to estimate the fair value of the intangible assets acquired, which was derived based on financial metrics of comparable companies operating in Indilinx’s industry. In determining the appropriate discount rates to use in valuing each of the individual intangible assets, the Company adjusted the overall discount rate giving consideration to the specific risk factors of each asset. The following methods were used to value the identified intangible assets:
		•		Existing technology: The fair value of the existing technology assets acquired was established based on their highest and best use by a market participant using the “Royalty Savings Method”. In the Royalty Savings Method, the value of an asset is estimated by capitalizing the royalties saved because the Company owns the asset. Expected cash flows were discounted at the Company’s weighted average cost of capital of 15%;
		•		In-process technology: As of the acquisition date, Indilinx was developing new versions and incremental improvements to its Barefoot product and the next generation SSD products. The in-process projects were at a stage of development that required further research and development to determine technical feasibility and commercial viability. The fair value of the in-process technology assets acquired was based on the valuation premise that the assets would be “In-Use” using a discounted cash flow model;
		•		Customer lists and related relationships: The fair value of the customer contracts and related relationships assets acquired was based on the Royalty Savings Method;
		•		Trademarks and trade names: The fair value of trade names/trademarks assets acquired was established based on the Royalty Savings Method.
	Identified intangible assets are being amortized over the following useful lives:
		•		Existing technology is estimated to have a useful life of one year;
		•		In-process technology will be amortized upon completion over its projected remaining useful life as assessed on the completion date. The majority of the in-process projects were completed by the end of fiscal 2013 with the remaining project expected to be completed in 2014;
		•		Customer contracts and related relationships are being amortized over their estimated useful life of five years;
		•		Trade names/trademarks are being amortized over their estimated useful life of ten years.
	The existing technology, patents/core technology, customer contracts, and related relationships and trade names/trademarks are amortized using the straight-line method.
	PLX
	On October 24, 2011, the Company completed the acquisition of certain assets and liabilities from PLX Technology Inc. (“PLX”) in exchange for cash consideration of $2.2 million. Pursuant to the agreement, the Company obtained a non-exclusive perpetual license related to consumer storage technology, capital equipment and assumed an approximately 40 person engineering Design Team located in Abingdon, United Kingdom. This transaction further strengthened the Company’s global research and development team and provides further access to advanced technology in an effort to accelerate solid state development, reducing the time to market for the next generation of SSD products, while also reducing development costs. The Company also incurred a total of $0.2 million of transaction costs which were primarily comprised of legal, accounting and valuation expenses and are classified as “Acquisition-Related Charges” on the Consolidated Statement of Operations for the year ended February 29, 2012.
	The following table summarizes the allocation of the purchase price based on the fair value of the assets acquired and the liabilities assumed at the date of acquisition (in thousands):
	Prepaid assets		$	20
	Fixed assets			499
	Intellectual property technology license			1,015
	Goodwill			794
	Total assets acquired			2,328
	Accrued liabilities			(128	)
	Total acquisition consideration		$	2,200
	Mr. Ralph Schmitt, PLX Technology Inc.’s Chief Executive Office (“CEO”), is also a member of OCZ’s Board of Directors. Throughout the term of the negotiations and up to the date of the acquisition, he removed himself from all discussions and had no authority to make decisions or influence the outcome of the arrangement. In October 2012, Mr. Schmitt became the CEO of OCZ
	On November 10, 2011, OCZ UK Limited was formed in the United Kingdom and all acquired assets and employees from PLX were transferred into this new entity. The results of operations from the PLX acquisition are included in the Company’s Consolidated Statements of Operations from October 24, 2011, the closing date of the acquisition.
	Sanrad
	On January 9, 2012, OCZ completed the acquisition of 100% of the equity interests of Sanrad Inc., (“Sanrad”) a United States based privately-held company and its wholly-owned subsidiary organized under the laws of Israel. Sanrad’s products and solutions are comprised of cutting-edge cloud storage acceleration and virtualization software and hardware for datacenters. Sanrad’s virtualization software and solutions transforms storage access in virtualized environments with NAND flash allowing data centers to fully leverage their storage investments. At the time of acquisition, Sanrad’s products included VXL software which is deployed as a virtual appliance on the host server, distributing FLASH resources on demand across application virtual machines to maximize the performance of key applications.
	The acquisition of Sanrad is expected to expand OCZ’s presence in the enterprise solid state drive strategy and is expected to accelerate the adoption of OCZ’s PCIe-based flash storage solutions in virtualized environments. The acquisition is also intended to broaden OCZ’s intellectual property resulting from Sanrad’s portfolio of three key patents and patent applications. In addition, the acquisition provided an assembled workforce, the implicit value of future cost savings as a result of combining entities, and is expected to provide OCZ with future unidentified new products and technologies. These opportunities were significant factors to the establishment of the purchase price, which exceeded the fair value of Sanrad’s net tangible and intangible assets acquired, resulting in goodwill of $14.2 million that was recorded in connection with this acquisition. See Note 8. Goodwill.
	The total acquisition consideration of $16.9 million consisted of the fair value of 2.1 million shares of OCZ common stock valued at the closing market price of $8.10 per share on January 9, 2012. The Company also incurred a total of $0.9 million of transaction costs which were primarily related to legal, accounting and valuation expenses in the year ended February 29, 2012. These transaction costs are classified as “Acquisition-Related Charges” on the Consolidated Statement of Operations for the year ended February 29, 2012.
	The results of operations of Sanrad are included in OCZ’s Consolidated Statements of Operations from January 9, 2012, the date of acquisition. The following table summarizes the fair value of the assets acquired and the liabilities assumed at the date of acquisition (restated and in thousands):
	Cash and cash equivalents		$	731
	Other current assets			150
	Fixed assets			23
	Intangible assets
	Existing technology			3,600
	Trademarks and trade names			100
	Goodwill			14,211
	Total assets acquired			18,815
	Accrued liabilities			(973	)
	Deferred tax liabilities			(925	)
	Total acquisition consideration		$	16,917
	The Company used an overall discount rate of approximately 12% to estimate the fair value of the identified intangible assets acquired, which was derived based on financial metrics of comparable companies operating in Sanrad’s industry. In determining the appropriate discount rates to use in valuing each of the individual intangible assets, the Company adjusted the overall discount rate giving consideration to the specific risk factors of each asset. The following methods were used to value the identified intangible assets:
		•		The fair value of the existing technology assets acquired was established based on their highest and best use by a market participant using the “Income Approach.” The Income Approach included an analysis of the markets, cash flows and risks associated with achieving such cash flows to calculate the fair value; expected cash flows were discounted at the Company’s weighted average cost of capital of 10%;
		•		The fair value of trade names/trademarks assets acquired was established based on their highest and best use by a market participant using the “Royalty Savings Method”. In the Royalty Savings Method, the value of an asset is estimated by capitalizing the royalties saved because the Company owns the asset. Expected cash flows were discounted at the Company’s weighted average cost of capital of 10%.
Identified intangible assets are being amortized over periods which reflect the pattern in which economic benefits of the assets are expected to be realized:
	•		Existing technology is estimated to have a useful life of five years;
	•		Trade names/trademarks are being amortized over their estimated useful life of two years.
The trade names/trademarks are amortized using the straight-line method, which reflects future projected cash flows. Existing technology will begin to be amortized over an expected useful life of five years based on the pattern in which the economic benefits are being consumed, which will be upon generation of revenue.
The excess of the total acquisition consideration over the fair value amounts assigned to the assets acquired and the liabilities assumed represents the goodwill amount resulting from the acquisition. We believe that the factors that contributed to goodwill include synergies that are specific to our consolidated business and not available to market participants, the acquisition of a talented workforce and a platform for developing and commercializing pharmaceutical products, as well as other intangible assets that do not qualify for separate recognition.

	Balance at end of year	$	1,160		$	11,087
	Common stock warrant liability is revalued to the estimated fair value at the end of each reporting period. Beginning in fiscal year 2013, the estimated fair value of the common stock warrant liability is calculated by management with the assistance of an independent third-party valuation firm using the Monte Carlo simulation model. Prior to fiscal year 2013, the Company calculated fair value using the Black-Scholes valuation model, which approximated fair value under the Monte Carlo simulation model. Fair value of the common stock warrant liability is classified as Level 3 due to the models reliance upon significant unobservable inputs.

Goodwill and Other Intangible Assets	12 Months Ended

Goodwill and Other Intangible Assets	8. Goodwill and Other Intangible Assets
	Goodwill
	As of February 28/29, 2013 and 2012, the carrying amount of goodwill was zero. The following is a summary of the goodwill activity for the year ended February 29, 2012 (restated, in thousands):
	Goodwill
	Balance as of February 28, 2011	$	9,989
	Acquisition of Indilinx		36,858
	Acquisition of PLX		794
	Acquisition of Sanrad		14,211
	Impairment		(61,852	)
	Balance as of February 29, 2012	$	—
	Goodwill represents the excess of the purchase price paid over the estimated fair value of the net assets acquired in a business combination. Goodwill is reviewed annually or whenever events or circumstances occur which indicate that goodwill might be impaired. Established accounting guidance provides for a two-step approach to determining whether and by how much goodwill has been impaired. The first step requires a comparison of the fair value of the Company to its net book value. If the fair value is greater, then no impairment is deemed to have occurred. If the fair value is less, then the second step must be performed to determine the amount, if any, of actual impairment. The process of evaluating the potential impairment of goodwill is highly subjective and requires significant judgment.
	The Company originally performed its annual impairment test of goodwill as of February 29, 2012, and determined in step one that its enterprise value exceeded the carrying value of its net assets, and therefore no goodwill impairment existed. However, based upon the errors and related control weaknesses described in Note 2, the significant operating losses generated and reductions in its revenue forecasts, the Company reperformed its impairment test as of February 29, 2012. During step one of this reperformance, the Company reassessed the enterprise value used in its impairment calculation using a combination of market-based metrics based upon peer group metrics and discounted cash flow projections, and determined that the carrying value of its assets exceeded its enterprise value. Therefore, the Company determined that step two was required. Prior to performing step two, a fair value determination of non-goodwill long-lived assets was made, and it was determined that no impairment for the non-goodwill long-lived assets had occurred.
	In step two of the goodwill impairment test, with the assistance of a third party valuation firm, the Company allocated the fair value of the reporting unit to all of its assets and liabilities as if the Company had been acquired in a business combination and the estimated fair value was the price paid to acquire the Company. The excess of the fair value of the Company over the amount assigned to its assets and liabilities is the implied fair value of goodwill. Based upon step two of the goodwill impairment calculation that was reperformed, the Company determined that goodwill had no implied fair value, and therefore the Company recognized an impairment charge of $61.9 million in the fourth quarter of fiscal 2012, representing a write-off of the entire amount of the Company’s previously-recorded goodwill.
	In November 2010, the Company acquired certain assets of Solid Data Systems, Inc. (“SDS”) and paid $0.4 million cash and issued 160,000 shares in restricted stock with a value of $0.6 million. The Company determined that it acquired as identifiable assets, IPR&D projects and fixed assets, with goodwill also resulting from the transaction. Following the acquisition, the Company determined that a charge should be recorded to impair the value of the goodwill and intangible assets acquired. Accordingly, an impairment charge of $1.0 million was recorded in the third quarter of fiscal 2011 which is included in “Impairment of goodwill and intangible assets” in the Consolidated Statement of Operations for the year ended February 28, 2011.
	Intangible Assets
	The following is a summary of the carrying amount of intangible assets for the fiscal years ended February 2013 and 2012 (in thousands):

	Intangible assets	$	9,717		$	(851	)	$	—		$	8,866
	During the second quarter of fiscal 2013, the Company discontinued certain product lines for which the core technology had been acquired in connection with the Indilinx acquisition. The Company recorded a charge of $0.8 million for the write-off of these intangible assets. In addition, concurrent with the 2013 Initiative Plan in the third quarter of fiscal 2013 (see Note 17), the Company discontinued other specific product lines for which certain licensed technology had previously been acquired. The Company recorded a charge of $1.4 million for the write-off of these intangible assets. The write-off for the intangible assets is included in “Impairment of goodwill and intangible assets” in the Consolidated Statement of Operations for the year ended February 28, 2013.
	In fiscal 2012, the Company purchased $2.5 million of intangible assets consisting of a $2.0 million technology license with an estimated useful life of three years and a $0.5 million technology license with an estimated useful life of two years. During fiscal 2013, the Company purchased $0.2 million of patent intellectual property with an estimated life of three years. Amortization of licensed technology is recorded on a straight-line basis.
	The IPR&D intangible assets are classified as indefinite lived assets that are not currently subject to amortization but are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The IPR&D assets will be subject to amortization upon completion of their respective research projects and commercialization begins. The fair value assigned to IPR&D assets was determined using the income approach based on estimates and judgments regarding risks inherent in the development process, including the likelihood of achieving technological success and market acceptance. If an IPR&D project is abandoned, the acquired technology attributable to the project will be written-off.
	For the years ended February 2013, 2012 and 2011, the Company recorded $1.9 million, $0.6 million and $0.1 million of amortization expense, respectively, for identified intangibles, of which $0.7 million and $0.1 million was included in cost of revenue during fiscal 2013 and 2012. No amortization was included in cost of revenue during fiscal year ended February 2011.
	The estimated future amortization expense of finite-lived intangible assets is as follows as of February 28, 2013 (in thousands):
		Cost of			Operating			Total
		Revenue			Expenses
	Future amortization expense:
	2014	$	918		$	607		$	1,525

	Litigation
	Taiwan Vendor Claim
	In July 2010, the Company received notice that a former vendor had filed legal proceedings in Taiwan demanding payment for materials which it contended were defective. As of February 28, 2011 the Company accrued $1.3 million for this contingency including potential interest costs which was included in general and administrative expense in the Consolidated Statement of Operations. On April 25, 2011, the Taoyuan District Court found in favor of the former vendor and the Company was ordered to pay $1.2 million plus interest of $0.2 million. During June 2011, these payments were made to the vendor and the case was formally closed.
	Product Quality Claim
	On March 24, 2011, a purported class action suit was filed in the United States District Court for the Northern District of California San Jose Division alleging that certain of the Company’s SSDs sold on or after January 1, 2011 did not meet certain performance criteria and as a result the Company engaged in certain deceptive practices and violated various laws. Among other things, the suit seeks unspecified actual and compensatory damages, as well as punitive damages, restitution, disgorgement and injunctive and other equitable relief. The Company believes that the lawsuit has no merit and the Company intends to vigorously defend against this litigation.
	Patent Infringement Claim
	On September 7, 2011 a complaint for patent infringement was filed by a storage technology company in the United States District Court for the Eastern District of Texas alleging patent infringement against OCZ and eight other companies. The Company was served with a copy of the complaint on October 26, 2011 and filed six affirmative defenses in response on December 23, 2011. The plaintiff was seeking an injunction and unspecified damages, special damages, interest and compulsory royalty payments. On January 5, 2013, the Company entered into a SSD patent settlement and license agreement under which the Company was granted a worldwide, perpetual, irrevocable, non-exclusive and non-transferable, royalty-bearing license in exchange for payments of $200,000 in January 2013, $300,000 in January 2014 and $500,000 in January 2015. In addition, the Company will pay royalties of 1% of the net sales of SSD products sold in excess of $100 million with the total not to exceed $2 million for each calendar year 2014, 2015, 2016, and 2017. The license will be fully paid after December 2017.
	Shareholder Litigation
	A number of shareholder lawsuits, both class action and derivative, have been filed against the Company and certain of its current and former officers and directors, as detailed more fully in Item 3, Legal Proceedings. Between October 11, 2012 and November 6, 2012, a number of putative class action lawsuits were filed in the United States District Court for the Northern District of California against the Company, its former Chief Executive Officer, and its former Chief Financial Officer. The shareholder class action lawsuits subsequently were consolidated. The consolidated amended complaint asserts claims for alleged violations of the federal securities laws and seeks unspecified money damages and other relief on behalf of a putative class of persons who purchased or otherwise acquired OCZ common stock and/or call options between July 6, 2011 and January 22, 2013. The parties have reached an agreement in principle to settle the consolidated class action. The settlement is subject to negotiation of final documentation and court approval.
	Between October 29, 2012 and December 14, 2012, three shareholder derivative lawsuits were filed in the United States District Court for the Northern District of California against certain of the Company’s current and former officers and directors. OCZ is named as a nominal defendant. The federal derivative lawsuits subsequently were consolidated. The consolidated complaint in the Federal Derivative Action asserts claims for alleged breaches of fiduciary duties, waste of corporate assets, and unjust enrichment and generally alleges that the defendants misrepresented and/or failed to disclose material information regarding the Company’s business and financial results and failed to maintain adequate internal and financial controls. The consolidated derivative complaint seeks unspecified monetary damages, equitable and/or injunctive relief, restitution, disgorgement, attorneys’ fees and costs, and other relief. In May 2013, the parties reached a settlement in principle of the Federal Derivative Action. The settlement is subject to court approval. On October 2, 2013, the Company announced that it has reached a settlement in principle in the federal shareholder class action litigation filed in connection with the Company’s previously announced financial restatement. See Note 19.
	Three shareholder derivative lawsuits also were filed in Santa Clara County Superior Court against certain of the Company’s current and former officers and directors (the “State Derivative Actions”). The Company is named as a nominal defendant and/or party in the State Derivative Actions. The State Derivative Actions have been stayed pending the resolution of the Federal Derivative Action.
	An unfavorable outcome in the above-referenced shareholder lawsuits could have a material adverse effect on our business, financial condition, results of operations, and cash flows.
	Securities and Exchange Commission Investigation
	On November 15, 2012, the Company received a letter from the SEC indicating that the SEC is conducting an investigation. In connection with the investigation, the Company received subpoenas requesting that the Company produce certain documents relating to, among other things, our historical financial statements. The Company is cooperating fully with the SEC’s investigation. This investigation could have a material adverse effect on our business, financial condition, results of operations, and cash flows.
	Class Action Litigation
	On March 24, 2011, a purported class action suit was filed in the United States District Court for the Northern District of California, San Jose Division, alleging that certain of OCZ’s SSDs sold after January 1, 2011 did not meet certain speed and storage criteria and, as a result, the Company supposedly engaged in certain deceptive practices and violated various laws. Among other things, the suit sought unspecified actual and compensatory damages, as well as punitive damages, restitution, disgorgement, and injunctive and other equitable relief. On January 4, 2013, the parties entered into a Confidential Settlement Agreement and Release (the “Settlement Agreement”), as a result of which the individual plaintiff dismissed the case and released OCZ of all liability in connection therewith. The Settlement Agreement also contains an agreement by Plaintiffs’ Counsel that they did not intend to file any claim against OCZ in connection with any of the claims that were asserted or could have been asserted in the lawsuit. The Court dismissed the case with prejudice on January 9, 2013.
	Failure to Satisfy a Continued Listing Rule
	On October 17, 2012, the Company received notice from the Nasdaq OMX Group (“Nasdaq”) stating that the Company was not in compliance with Listing Rule 5250(c)(1) (“the Rule”) for continued listing due to the Company’s inability to file with the SEC the Company’s Quarterly Report on Form 10-Q for the quarter ended August 31, 2012 (the “Initial Delinquent Filing”) on a timely basis. The notification was issued in accordance with standard Nasdaq procedures and had no immediate effect on the listing or trading of the Company’s common stock on the Nasdaq Capital Market. Pursuant to Nasdaq’s letter dated October 17, 2012, the Company had 60 calendar days of the date of the Nasdaq notification letter to submit a plan to regain compliance with respect to the Initial Delinquent Filing. On December 17, 2012, the Company submitted its plan to regain compliance. On December 20, 2012, the Company was informed that Nasdaq had granted an exception to its rules to enable the Company to regain compliance by February 28, 2013. On January 17, 2013, the Company received another letter from Nasdaq, as a result of its inability to file with the SEC its Form 10-Q for the period ending November 30, 2012 by its required filing deadline (the “Second Delinquent Filing”). In that letter, Nasdaq noted that the Second Delinquent Filing was an additional instance of non-compliance which could lead to delisting from Nasdaq. The Nasdaq letter noted that the Company was required to submit an update to its original plan to regain compliance with Nasdaq’s filing requirements for continued listing no later than February 1, 2013. Upon acceptance of the Company’s compliance plan, Nasdaq was permitted to grant an extension of up to 180 days from the Initial Delinquent Filing, or until April 8, 2013, for the Company to regain compliance with Nasdaq’s filing requirements for continued listing. On February 19, 2013, the Company received a third letter from Nasdaq. In that letter, Nasdaq accepted the Company’s plan to regain compliance, which permitted the continued listing of the Company’s stock on the Nasdaq Capital Markets. Under the terms of the revised exception, on or before April 8, 2013, the Company must have filed its Forms 10-Q for the period ended August 31, 2012 and November 30, 2012, and any other delinquent periodic reports as required by the Rule. The Company announced on April 8, 2013 that it would not be able to file its second and third quarter Forms 10-Q prior to the April 8, 2013 extended filing deadline previously established by Nasdaq, resulting in continued noncompliance with the Rule for those filings. On May 28, 2013 the Company received a determination from the NASDAQ Listing Qualifications Panel (the “Panel”) indicating that the Panel had granted the Company’s request to remain listed on The NASDAQ Stock Market, subject to the condition that the Company is current in the filing of its periodic reports with the Securities and Exchange Commission by September 16, 2013.

Common_Stock_Warrant_Liability

Common Stock Warrant Liability	12 Months Ended
	Feb. 28, 2013
Common Stock Warrant Liability	10. Common Stock Warrant Liability
	In March 2010, OCZ issued warrants to purchase up to 2,575,833 shares of its common stock at $5.25 per share in connection with a private placement of its common stock. These common stock warrants contain certain embedded conversion features and provisions which are subject to anti-dilution adjustments requiring the fair value of the common stock warrants to be reflected on the balance sheet as a liability. The estimated fair value of the common stock warrants of $2.1 million upon issuance was recorded as a liability with a corresponding reduction of additional paid-in capital. As a result of the Company’s November 2, 2010 private placement equity financing, the anti-dilution feature contained in these common stock warrants was triggered which resulted in a new exercise price of $4.87 per share.
	At each reporting period, the common stock warrant liability is revalued to its estimated current fair value with changes to the estimated fair value recognized in the Consolidated Statement of Operations. Beginning in fiscal year 2013, the estimated fair value of the warrant liability was determined by the Company with the assistance of an independent third-party valuation specialist using the Monte Carlo simulation model. Prior to fiscal year 2013, the Company determined the estimated fair value using the Black-Scholes valuation model, which approximated the fair value as calculated under the Monte Carlo simulation model. The fair value of the common stock warrant liability is classified as Level 3 due to the models reliance upon significant unobservable inputs.
	The common stock warrant liability requires remeasurement to fair value upon each reporting date while the underlying common stock warrants are outstanding and accordingly, the Company has recognized revaluation (income)/expense adjustments in the Consolidated Statements of Operations for the fiscal years ended February 2013, 2012 and 2011 of $(9.9) million, $4.3 million and $7.9 million, respectively.
	The fair value of the common stock warrant liability for the fiscal years ended February 2013 and, 2012 was calculated using the following assumptions:
		Years Ended
		February 28/29,
		2013			2012			2011
	Share price	$	1.73		$	8.6		$	7.57
	Expected life (in years)		2.1			3.1			4.1
	Risk free interest rate		0.3	%		0.9	%		2.1	%
	Volatility		105	%		78	%		43	%
	Dividend yield		0	%		0	%		0	%
	At February 28, 2013 and February 29, 2012, the Company had a total of 1,979,168 and 1,999,168 outstanding common stock warrants, respectively, underlying the common stock warrant liability. These warrants will expire on March 23, 2015 and may be exercised at any time at the option of the holders and may be exercised on a cashless basis. During the fiscal years ended February 28, 2013 and February 28, 2011, warrant holders exercised 20,000 and 43,332 warrants, respectively, for cash. During the fiscal years ended February 29, 2012 and February 28, 2011, warrant holders exercised 416,666 and 116,667 warrants on a cashless basis resulting in the issuance of 199,567 and 36,866 common shares, respectively.

Credit_Facilities

Credit Facilities	12 Months Ended
	Feb. 28, 2013
Credit Facilities	11. Credit Facilities
	Silicon Valley Bank Asset-Based Financing Agreement
	In February 2011 the Company signed a new agreement with Silicon Valley Bank (“SVB”) for an asset-based financing of up to $25 million (the “SVB Agreement”), which replaced a previous $10.0 million Loan and Security Agreement with SVB. The SVB Agreement, which was amended and restated in February 2012, expired on May 6, 2012, expanded the $17.5 million debt capability available under the prior joint factoring loan arrangements with SVB and Faunus Group International, Inc. (“FGI”). Upon completion of the SVB Agreement, the Company also terminated its Sale of Accounts and Security Agreement (“FGI Agreement”) with FGI. As part of the termination of the FGI Agreement, a contractual penalty of $0.2 million was paid to FGI and is included in the “Interest and financing costs” caption on the Consolidated Statement of Operations for the year ended February 28, 2011.
	The SVB Agreement contained financial covenants for quarterly EBITDA, as defined in the agreement, and a monthly quick ratio computation (the Company’s cash and accounts receivable divided by current liabilities). Interest rates ranged between prime plus 1.5% to prime plus 2.5%. There were also provisions for letter of credit sub-limits and various operational, reporting, restrictions of cash dividends, negative and affirmative covenants with which the Company must comply. On January 31, 2012 the Company executed an amendment to provide a formal waiver of the Sanrad acquisition as well as to extend the SVB Agreement until May 6, 2012. On April 25, 2012 the Company executed an amendment to provide a formal waiver of the covenant for EBITDA levels for the period ending February 29, 2012. As of February 29, 2012, the Company had no borrowings under the SVB Agreement, which expired May 6, 2012.
	Wells Fargo Capital Finance Senior Secured Credit Facility
	On May 10, 2012 the Company signed an agreement with Wells Fargo Capital Finance (“WFCF”) for a $35 million senior secured credit facility (“WFCF facility”) to replace the SVB Agreement. As in the SVB Agreement, borrowings under the WFCF facility were limited to a borrowing base based on the Company’s receivables. The WFCF facility had a 5-year term and provided for a committed expansion up to $60 million of cumulative borrowings and for a potential further expansion to $100 million of total borrowings, in each case if certain conditions were met. The WFCF facility contained minimum liquidity levels and certain financial covenants if these levels were not met. There were also two interest rate options using either a “Base Rate” or a “LIBOR Rate” as defined, both of which contained an “Applicable Margin” spread ranging from 1.25% to 2.75% depending on the “Excess Availability” as defined.
	On October 12, 2012, the Company entered into Amendment No. 1 to the WFCF facility dated May 10, 2012, which redefined certain calculations within the borrowing base and required weekly rather than monthly monitoring of minimum liquidity levels.
	On January 15, 2013, the Company entered into Amendment No. 2 to the WFCF facility as the Company was in violation of certain covenants which included its failure to meet a minimum EBITDA requirement. Amendment No. 2 kept the line of credit available commencing January 15, 2013 and ending on the earlier of (i) February 15, 2013, or such later date as the Company and WFCF agreed to in writing; (ii) the occurrence of any Event of Default; or (iii) the occurrence of any Termination Event.
	In addition, the Company agreed to certain additional terms and conditions, including: (1) the Company did not have the right to exercise the LIBOR option until WFCF delivered notice to the Company agreeing to reinstate the LIBOR option. Without the LIBOR option, loans under the Credit Agreement bore interest at a Base Rate plus a spread, with the effect that the interest rate increased by approximately 2%; (2) upon the expiration or termination of the Amendment No. 2 period, WFCF would have no further obligation to make loans under the Credit Agreement; (3) the amount of loans outstanding under the Credit Agreement was limited to (i) $35.0 million less (ii) the letters of credit at such time, plus the principal amount of swing loans outstanding, plus a new availability block of $15.0 million; (4) WFCF established a new availability reserve of $5.0 million against the borrowing base; (5) the Company agreed to pledge 65% of the voting equity interest of Indilinx, the Company’s Korean subsidiary; (6) the Company agreed to not permit Liquidity to be less than $10.0 million for more than one consecutive day; (7) the Company paid an amendment fee of $0.1 million; (8) the Company agreed to cause Indilinx to transfer to the Company no later than February 28, 2013 all of its material assets; (9) the committed expansion by WFCF to up to $60.0 million of cumulative borrowings was eliminated; and (10) the Company agreed to release certain claims against WFCF.
	At February 28, 2013, no borrowings were outstanding under the WFCF facility. Subsequent to the end of fiscal 2013, the Company terminated the Wells Fargo Capital Finance facility and entered into a separate financing arrangement with Hercules Technology Growth Capital, Inc. See Note 19.

	Preferred Stock
	OCZ has 20,000,000 authorized shares of preferred stock. On October 25, 2011, the Company designated 100,000 of these shares as Series A Junior Participating Preferred Stock in connection with the Board’s same day approval and adoption of a stockholder rights plan. Under the plan, OCZ declared and paid a dividend of one preferred share purchase right for each share of OCZ common stock held by the Company’s stockholders of record as of the close of business on November 4, 2011. Each preferred share purchase right entitles the holder to purchase from the Company one one-hundredth of a share of Series A Junior Participating Preferred Stock, par value $0.0025 per share, at a price of $35.00, subject to adjustment. The rights are not exercisable until the distribution date. The distribution date is defined as when an acquisition of 20% or more of the Company’s common stock by an acquiring person has occurred. The stockholder rights plan may have the effect of deterring or delaying a change in control of OCZ.

	The weighted-average remaining contractual life of all vested and expected-to-vest stock options at February 28, 2013 was 8.4 years. The weighted-average remaining contractual life for all exercisable stock options at February 28, 2013 was 7.5 years. The weighted-average remaining contractual life of all expected-to-vest RSUs at February 28, 2013 was 1.7 years.
	The aggregate intrinsic value of options exercisable at February 28, 2013 was $0.2 million. The aggregate intrinsic value of stock options vested and expected to vest was $0.2 million at February 28, 2013. The aggregate intrinsic value of RSUs expected to vest was $1.0 million at February 28, 2013. For stock options, aggregate intrinsic value represents the differences between the exercise price of dilutive stock options and the closing price of the Company’s stock of $1.73 on February, 28, 2013. For RSUs, aggregate intrinsic value represents RSUs valued at the closing price of the Company’s stock on February 28, 2013.
	The following table provides supplemental information pertaining to stock option and RSU exercise activity for fiscal years ended February 2013, 2012 and 2011 (in thousands, except fair values):
		Years Ended February 28/29,
		2013			2012			2011
	Stock options:
	Weighted-average fair value of options granted per share	$	2.93		$	4.17		$	1.76

	Restricted stock units:
	Intrinsic value of restricted stock units vested	$	774		$	—		$	—
	The intrinsic value of exercised stock options is calculated based on the difference between the exercise price and the closing stock price of the Company’s stock on the date of exercise. The intrinsic value of vested RSUs vested is calculated based on the Company’s stock price on the date of vesting.
	Stock-based compensation
	The following table summarizes stock-based compensation costs in OCZ’s Consolidated Statements of Operations for the fiscal years ended February 2013, 2012 and 2011 (in thousands):
		Years Ended February 28/29,

	Stock-based compensation by category of expense:
	Cost of revenue	$	765		$	278		$	183

	Sales and marketing		1,823			950			340

	Total stock-based compensation	$	8,354		$	3,581		$	1,028
	Stock-based compensation by category of expense:
	Stock options	$	6,242		$	3,581		$	1,028
	Restricted stock units		2,112			—			—
	Total stock-based compensation	$	8,354		$	3,581		$	1,028
	Stock-based compensation in the fiscal year ended February 28, 2013 includes $0.1 million resulting from the August 2012 retirement agreement entered into between the Company and its Chief Financial Officer. The agreement extended the post-employment exercise period of vested stock options when he retires. Stock-based compensation due to this modification was calculated as of the date of the agreement based upon the difference in fair value of the underlying stock options immediately before and immediately after the modification.
	The Company did not capitalize any stock-based compensation as inventory in the years ended February 2013, 2012 and 2011 as such amounts were immaterial.
	The fair value of RSU’s is determined on the date of grant based on the market price of the Company’s common stock. As of February 28, 2013, total unamortized stock-based compensation related to non-vested stock options and RSUs was $14.2 million and $1.5 million, respectively, which will be recognized over weighted-average periods of 3.0 years and 1.8 years, respectively.
	The fair value of each option grant is estimated on the date of grant using the Black-Scholes single option pricing model with the following assumptions:
		Years Ended February 28/29,
		2013			2012			2011
	Expected life (in years)		4.55			4.19			4.4
	Expected volatility		81	%		78	%		45	%
	Risk-free interest rate		0.7	%		1.2	%		1.9	%
	Dividend yield		0	%		0	%		0	%
The expected life for stock options under the stock incentive plan represents the weighted-average period that the stock options are expected to remain outstanding. The Company’s computation of expected life was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules, and expectations of future employee behavior.
The expected volatility is calculated using historical daily closing prices of the Company’s common stock.
The risk-free interest rate assumption is based upon observed interest rates appropriate for the term of OCZ’s employee stock options and employee stock purchase plan awards. The dividend yield assumption is based on the Company’s history and lack of an expectation of dividend payouts.

	2013 Initiative
	During fiscal 2013, the Company recorded restructuring charges of $1.7 million related to its 2013 Initiative Plan, which provided for a strategic transformation by streamlining product offerings and shifting sales channels towards enterprise and original equipment manufacturer (“OEM”) solutions in order to make the Company more efficient and profitable. The 2013 Initiative Plan included $1.4 million of severance charges related to terminating 228 employees. The majority of severance charges were related to the Company’s Korean facility as the Company prepares it for closure. Also included were a $0.2 million loss on disposal of fixed assets and a $0.1 million charge for legal and other fees related to the facility closure.
	All costs of the 2013 Initiative were completed and settled by February 28, 2013.

	As February 28, 2013, the Company has approximately $177 million for Federal and $127 million for California state net operating loss carryforwards, respectively, available to offset future taxable income. Any unused Federal carry forwards will expire between 2033 and 2034 and any unused California State carry-forwards will expire between 2033 and 2034.
	The following is a reconciliation of the difference between income taxes computed by applying the federal statutory rate of 34% and the benefit from income taxes for fiscal 2013, 2012 and 2011:

	We are required to evaluate the realizability of our deferred tax assets in both our U.S. and non-U.S. jurisdictions on an ongoing basis. In accordance with U.S. GAAP a valuation allowance is provided when it is more likely than not that the deferred tax assets will not be realized. During fiscal 2013 and 2012, we maintained a valuation allowance against our U.S. deferred tax assets. We intend to maintain a valuation allowance until sufficient positive evidence exists to support the realization of such deferred tax assets.
	During the year ended February 28, 2013, the unrecognized tax benefit (“UTB”) less accrued interest and penalties increased from $3.0 million to $4.6 million. Of the total $4.6 million of unrecognized tax benefits, $0.9 million represents the amount that if recognized, would unfavorably affect the Company’s effective income tax rate in a future period. The Company cannot conclude on the range of cash payments that will be made within the next twelve months associated with its uncertain tax positions.
	A reconciliation of the March 1, 2012 through February 28, 2013 amount of UTB is as follows (in thousands):
		February 28,			February 29,
		2013			2012

	Increases in unrecognized tax benefits related to current year’s UTB		1,643			3,024
	Balance at end of year	$	4,638		$	3,024
	The Company records interest and penalties related to unrecognized tax benefits in income tax expense. On February 28, 2013 the Company had $11,000 accrued for estimated interest and zero for estimated penalties related to uncertain tax positions. For the year ended February 28, 2013, the Company recorded estimated interest of $11,000 and estimated penalties of zero.
There were no unrecognized income tax benefits, including accrued interest and accrued penalties on February 28, 2013 related to tax positions for which it is reasonably possible that the statute of limitations will expire in various jurisdictions within the next twelve months.
The Company’s major tax jurisdictions are the United States federal, State of California, United Kingdom, Israel, and Taiwan, and the Company’s income tax returns are no longer subject to examination by these taxing authorities as follows:
Jurisdiction:	Tax Years
U.S. Federal		2006
California		2004
Israel		2011
Taiwan		2008
United Kingdom		2011
Management’s intent is to indefinitely reinvest any undistributed earnings from its foreign subsidiaries, accordingly no provision for federal and state income taxes has been provided thereon, nor is it practical to determine the amount of this liability. Upon distribution of those earnings in the form of dividends or otherwise, the Company will be subject to United States income taxes.

Adjustments were recorded to reverse the original revenue recorded, defer the original revenue recorded or provide reserves against net revenue for future product returns. Also included are adjustments to recognize the reversal of the product cost, which are recorded as reductions of cost of revenue and increases to either inventory or deferred product cost.

	On April 11, 2013, the Company received a letter from Nasdaq stating that unless the Company requested a hearing before the Nasdaq Hearing Panel that the Company’s common stock would be subject to delisting from Nasdaq for noncompliance with the Rule with respect to its failure to file on a timely basis its Forms 10-Q for the period ended August 31, 2012 and November 30, 2012. The Company announced on April 8, 2013 that it would not be able to file its second and third quarter Forms 10-Q prior to the April 8, 2013 extended filing deadline previously established by Nasdaq, resulting in continued noncompliance with the Rule for those filings. On May 28, 2013 the Company received a determination from the NASDAQ Listing Qualifications Panel (the “Panel”) indicating that the Panel had granted the Company’s request to remain listed on The NASDAQ Stock Market, subject to the condition that the Company is current in the filing of its periodic reports with the Securities and Exchange Commission by September 16, 2013. On September 12, 2013, the NASDAQ Listing Qualifications panel granted the Company’s request to remain listed on The NASDAQ Stock Market, subject to the condition that the Company becomes current in the filings of its periodic reports with the Securities and Exchange Commission by October 7, 2013.

	Hercules Technology Growth Capital, Inc. Loan and Security Agreement
	On March 11, 2013, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Hercules Technology Growth Capital, Inc. (“Hercules”), pursuant to which a Term Loan of up to an aggregate principal amount of $15 million and a revolving loan facility (“Loan Facility”) up to an aggregate principal amount of $15 million was available to the Company pursuant to the terms and conditions thereof. The Company’s availability under the Loan Facility was limited to a borrowing base of eligible accounts receivable (less certain reserves) multiplied by an advance rate.
	The Loan Agreement provides for an initial Term Loan advance of $10 million, which closed on March 11, 2013, and an additional Term Loan advance of up to $5 million, which was contingent upon the Company being current in its SEC filings and achieving certain revenue levels for two consecutive quarters. During the first year, the Term Loan would bear interest in cash at an annual interest rate equal to the greater of 12.50% or prime plus 8.75%. After the first year, if no event of default exists on the first anniversary of the closing of the Loan Agreement, the Term Loan would bear interest in cash at an annual rate equal to the greater of 10% or prime plus 6.25%. In addition to cash interest, the Term Loan would accrue payment in kind (“PIK”) interest at a PIK interest rate of 3.0% per year. The Loan Agreement provided for interest-only payments on the Term Loan for six months and repayment of the aggregate outstanding principal balance of the Term Loan in monthly installments starting on November 1, 2013 and continuing through April 1, 2016.
	The Loan Agreement also provides the Company access to the $10 million Loan Facility which must be repaid in full on April 1, 2016. An additional $5 million of the Loan Facility would be available to the Company upon its obtaining additional financing of at least $10 million. The loans under the Loan Facility will bear interest at an annual rate equal to the greater of 9% or prime plus 5.25%. The Company is also obligated to pay an unused line fee on the Loan Facility of 0.50% per annum times the unused portion of the Loan Facility. Unless the Loan Facility has been terminated prior to either such date, on each of the first and second anniversaries of the closing date of the Loan Agreement, the Company was obligated to pay a fee of 1.0% times the Loan Facility.
	Upon the occurrence and during the continuation of an event of default under the Loan Agreement, the interest rate applicable to both the Term Loan and the Loan Facility would be increased by 2% per annum.
	If all loans under the Loan Agreement are repaid and the Loan Facility was terminated prior to the scheduled maturity of the Loan Agreement, the Company would be obligated to pay a prepayment charge to Hercules equal to: if prepaid and terminated in any of the first 12 months following the closing date, 2.00% of the amount of the Term Loan and the Loan Facility; after 12 months following the closing date but prior to 24 months following the Closing Date, 1.50% of the amount of the Term Loan and the Loan Facility; and thereafter, 1.00% of the amount of the Term Loan and the Loan Facility. Additionally, the Loan Facility carries a loan termination fee of $0.4 million.
	Per the financial covenants, the Company must raise a minimum of $20.0 million in new equity or subordinated debt no later than January 31, 2014, of which $10.0 million in new equity or subordinated debt must be raised no later than May 31, 2013.
	The Loan Agreement contains customary representations and warranties and affirmative and negative covenants including, among others, covenants regarding the maintenance of certain financial tests, covenants relating to financial reporting, compliance with laws, limitations on debt, liens, dividends, investments, mergers and acquisitions and sales of the Company’s assets.
	In connection with the Loan Agreement, the Lender was granted a security interest in substantially all of the Company’s personal property domestic subsidiaries, whether now owned or hereafter acquired.
	Pursuant to the Loan Agreement, the Company issued Hercules a warrant (the “March Warrants”) to purchase 688,072 shares of its common stock at $2.18 per share. If the Company had consummated a financing of at least $10 million in new equity or subordinated debt prior to May 31, 2013 in which it issues shares of common stock or securities that were exercisable or convertible into shares of its common stock and the effective price per shares of common stock in that financing is less than the exercise price of the March Warrants, then the exercise price of the March Warrants would be reduced to equal the price per share of common stock in such financing and, as a result, the number of shares of common issuable upon exercise of the March Warrants would have been increased such that the product of the newly adjusted number of shares of common stock and the reduced exercise price per share would equal $1.5 million. Alternatively, if the Company consummates a financing of at least $10 million in new equity or subordinated debt prior to May 31, 2013 in which it issued shares of preferred stock or securities that were exercisable or convertible into shares of its preferred stock, then the holder of the March Warrants could have elected to have the March Warrants convert into $1.5 million of shares of our preferred stock or other securities at a price per share/security paid by the investors in the financing. The March Warrants had a term of five years from the date of issuance.
	In June 2013, the Company entered into an amendment to the Loan Agreement that redefined certain calculations with respect to the financial tests and extended the requirement to consummate such financing to June 21, 2013. The Company agreed to certain other terms and conditions, including an amendment to the March Warrants and the issuance of additional warrants to purchase that number of shares of the Company’s common stock equal to the quotient obtained by dividing $365,000 (the “Aggregate Amount”) by an exercise price which was initially set at $1.46 per share (the “June Warrants”), resulting in 250,000 shares of common stock issuable upon full exercise of the June Warrants; provided, that if the Company did not consummate a financing of new equity, together with any subordinated debt, of at least $10 million on or before June 18, 2013, the Aggregate Amount shall be increased by $73,000 each calendar day until the closing of such financing, each as defined and described below, and the payment of an amendment fee of $200,000. In addition, we reset the exercise price of the March Warrants to purchase 688,072 shares of common stock from $2.18 to $1.46 per share, resulting in 1,027,397 shares of common stock issuable upon full exercise of the March Warrant.
	In August 2013, the company entered into a second amendment to the Loan and Security Agreement (the “Second Amendment”). Under the Second Amendment:
		•	all outstanding amounts under the Hercules Loan Agreement, other than the Warrant Exchange Fee (as defined below), are due and payable June 1, 2014;
		•	Hercules may make advances under the revolving portion of the Hercules Loan Agreement in its sole discretion;
		•	the principal balance on the term loan outstanding on October 31, 2013 is repayable in equal monthly installments of principal and interest beginning November 1, 2013 (calculated on a mortgage style basis as if the final maturity date was 30 months after the date of the initial installment), with the balance due on June 1, 2014;
		•	the Company is required to provide Hercules with the Company’s audited financial statements for the fiscal years ended February 29, 2012 and February 28, 2013 as soon as practicable and in any event by September 16, 2013;
		•	certain covenants were amended to permit the Company to issue the Debentures and perform its obligations thereunder;
		•	if, prior to delivery of the Company’s financial statements for any fiscal quarter, the Company takes action to improve its liquidity to the satisfaction of Hercules, the quarterly EBITDA and minimum liquidity covenants will be deemed to be waived until delivery of the financial statements for the next fiscal quarter; and
		•	Hercules waived all events of default existing prior to the date of the Second Amendment.
	In addition, pursuant to the Second Amendment, the March Warrants and June Warrants were cancelled in exchange for a fee (the “Warrant Exchange Fee”) of $6.5 million, payable upon the earlier to occur of (a) the consummation of any sale of all or any material portion of the Company’s assets in one or a series of transactions, the merger, consolidation, share exchange or similar transaction of the Company with or into another corporation, company or other entity or a Change of Control (as defined in the Hercules Loan Agreement), (b) the payment in full in cash of the then outstanding principal amount of and all accrued and unpaid interest on the Debentures, (c) the Hercules term loan maturity date, or (d) the payment in full of the outstanding secured obligations under the Hercules Loan Agreement. However, the Second Amendment provides that the Company will not make and Hercules will not accept the payment of the Warrant Exchange Fee unless and until the principal amount of the outstanding Debentures and all accrued and unpaid interest, fees and other amounts due and payable thereon shall have been paid in full or otherwise converted into shares of common stock. The Warrant Exchange Fee does not bear interest but it is secured by the collateral under the Hercules Loan Agreement. As of the time immediately prior to the cancellation of the March Warrants and June Warrants, such warrants entitled Hercules to purchase 4,077,397 shares of the Company’s common stock at an exercise price of $1.46 per share, with the March Warrants to purchase 1,027,397 shares to expire in March 2018 and the June Warrants to purchase 3,050,000 shares to expire in June 2018. The March Warrants and the June Warrants were cancelled effective August 13, 2013.
	In September 2013, the Company entered into a third amendment to the Hercules Loan Agreement (the “Third Amendment”). Under the terms of the Third Amendment, the $200,000 facility modification charge included in the First Amendment was deferred from being currently due to being due upon facility termination.
	We currently are not in compliance with certain of our covenants regarding operating ratios and providing Hercules with audited financial statements as provided for under the Second Amendment, and there can be no assurances that we will be able to obtain a waiver for non-compliance and comply with these covenants in the future. If we do not obtain a waiver and maintain future compliance with the covenants in the Hercules Loan Agreement, the lender could declare a default. Any default under the Hercules Loan Agreements will allow the lender under the Loan Agreement the option to demand repayment of the indebtedness outstanding.
	Subordinate Senior Secured Convertible Debentures and Warrants
	Also in August 2013, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) under which it issued $13.1 million aggregate principal amount of 9% Subordinate Senior Secured Convertible Debentures due August 13, 2014 (the “Debentures”) at par and issued warrants to purchase 5,778,750 shares of Common Stock (the “August Warrants”) that are exercisable until August 13, 2018. The conversion price of the Debentures is $1.70 per share, and the exercise price for the August Warrants is $0.75 per share, both subject to adjustment. The Debentures are secured by a security interest in substantially all of the personal property of the Company. The indebtedness and obligations under the Debentures, as well as the liens securing such indebtedness and obligations, are subordinate to the Hercules Loan Agreement, except as otherwise described below.
	The Debentures are redeemable at the election of the holders at 125% of the then outstanding principal amount plus interest under certain circumstances if the Company enters into an agreement providing for the sale or transfer of control of the Company or a material portion of its respective assets. The Debentures are redeemable at the option of the Company in whole or in part from time to time, and the Company may cause the holders to convert all or part of the Debentures under certain conditions.
	The Debentures provide for customary events of default for transactions of this nature, including a cross-default provision under which an event of default may be declared by the holders if an event of default is declared and the repayment of borrowings is accelerated under any of the Company’s other credit agreements. If an event of default occurs under the Debentures, the holders may declare the outstanding principal amount thereof to be immediately due and payable. The amount due and payable in the event of an acceleration following an event of default would be the sum of (a) the greater of (i) the outstanding principal amount of the Debentures, plus all accrued and unpaid interest hereon, divided by the conversion price, multiplied by the volume weighted average price of the Common Stock over the period specified in the Debentures, or (ii) 125% of the outstanding principal amount of the Debentures, plus 100% of accrued and unpaid interest, and (b) all other amounts, costs, expenses and liquidated damages due in respect of the Debentures.
	If the Company is not current in its SEC filings at any time after six months following the date of the Purchase Agreement and prior to the date on which the Debentures, the August Warrants and the underlying shares may be resold by non-affiliates without restriction under Rule 144, it would owe liquidated damages equal to 2% of the principal amount of the Debentures per month until the Company makes the required SEC filings or the underlying shares may be resold by non-affiliates without complying with the current public information requirement of Rule 144. In connection with the Purchase Agreement, the Company entered into a Registration Rights Agreement with the parties to the Purchase Agreement pursuant to which the Company has agreed to file a registration statement with the SEC within 60 days of the closing to register the resale of the shares of common stock issuable upon conversion of the Debentures and upon exercise of the August Warrants. If the Company fails to file the registration statement when required, the registration statement is not declared effective when required or fails to remain effective during the period specified in the Registration Rights Agreement, then the Company would owe monthly liquidated damages equal to 2% of the aggregate purchase price paid for the Registrable Securities pursuant to the Purchase Agreement.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Feb. 28, 2013
Basis of preparation	Basis of preparation
	The accompanying consolidated financial statements include the accounts of OCZ and its wholly-owned subsidiaries in Canada, Israel, Korea and the United Kingdom. All intercompany transactions and balances have been eliminated. OCZ’s fiscal year begins on March 1 and ends on February 28 or 29. All material intercompany balances and transactions have been eliminated. The significant accounting policies used in the preparation of the financial statements are summarized below.
Reclassifications	Reclassifications
	Certain prior year balances have been reclassified to conform to the current year presentation.
Use of estimates	Use of estimates
	The preparation of these financial statements in conformity with generally accepted accounting principles (“GAAP’’) in the United States of America requires management to make estimates, assumptions and exercise judgment that affect the reported amounts of assets, liabilities, revenues and expenses and related note disclosures. The level of uncertainty in estimates and assumptions increases with the length of time until the underlying transactions are completed. Actual results may differ from those estimates.
	On an ongoing basis, the Company evaluates its estimates, including, among others, those related to bad debts and other related allowances, inventories and related reserves, income taxes, warranty obligations, fair value of common stock warrant liability stock-based compensation, business combinations, legal contingencies, realizability of goodwill and the assessment of recoverability of long-lived assets. The Company bases its estimates on historical experience and on other assumptions that it believes are reasonable under the circumstances, the results of which form the basis for its judgments about the carrying values of assets and liabilities when those values are not readily apparent from other sources. However, future results will differ from these estimates under different assumptions and conditions.
Cash Equivalents	Cash equivalents
	Cash equivalents are considered highly liquid investments purchased with an original maturity of three months or less.
Restricted Cash	Restricted Cash
	Restricted cash represents amounts designated for uses other than current operations. The Company periodically makes deposits of restricted cash for irrevocable letters of credit related to vendor obligations, and the lease of the Company’s corporate headquarters in San Jose, California.
Concentration of credit risks	Concentration of credit risks
	Financial instruments which potentially subject the Company to concentrations of credit risk include our cash and cash equivalents and uninsured accounts receivable.
	During the periods presented herein, the Company had deposits in banks in excess of the Federal Deposit Insurance Corporation insurance limit. The Company has not experienced any losses of such deposits to date. The Company is exposed to credit risk in the event of a default by the financial institutions holding our cash and cash equivalents to the extent recorded on the balance sheet. The Company is also subject to credit risk from our accounts receivable related to our product sales which are stated at the amount which management expects to collect. The Company’s trade accounts receivable do not bear interest. Customer creditworthiness is monitored and collateral is not required. The Company maintains credit insurance on the majority of its accounts receivable, and it has not experienced significant accounts receivable losses to date. It maintains a valuation allowance for doubtful accounts, estimated sales returns and CIP Credits. Management considers the following factors when determining the collectability of specific customer accounts: customer credit worthiness, transaction history, current economic trends and customer insurability. See Note 7.
Inventories	Inventories
	Inventories are stated at the lower of cost or market using the average cost method. OCZ establishes provisions for excess and obsolete inventories to reduce the carrying values of such inventories to their estimated net realizable value after evaluation of historical sales, future demand, market conditions and expected product life cycles. Such provisions are included in “Cost of revenue” in the Consolidated Statements of Operations.
	Consignment product shipped to some of the Company’s resellers is included in finished goods inventory. Inventory also includes estimated product to be returned to the Company as part of its allowance for sales returns. The Company includes consignment inventory and inventory expected to be returned within the category of inventory on its Consolidated Balance Sheets. See Note 7.
Property and Equipment	Property and equipment
	Property and equipment is recorded at cost. The cost of maintenance and repairs is expensed as incurred. Depreciation and amortization is computed using the straight line method over the estimated useful lives of the assets as follows:
	Vehicles		3 years
	Furniture and fixtures		3 — 5 years
	Equipment		3 — 5 years
	Leasehold improvements		Shorter of remaining lease term or estimated useful life.
Business Acquisitions	Business Acquisitions
	The Company’s consolidated financial statements include the operations of acquired businesses after the completion of the acquisitions. The Company accounts for acquired businesses using the acquisition method of accounting. The acquisition method of accounting for acquired businesses requires, among other things, that most assets acquired and liabilities assumed be recognized at their estimated fair values as of the acquisition date, with limited exceptions, and that the fair value of acquired intangible assets including in-process research and development, or IPR&D, be recorded on the balance sheet. Also, transaction costs are expensed as incurred. Any excess of the acquisition consideration over the assigned values of the net assets acquired is recorded as goodwill.
Goodwill	Goodwill
	Goodwill represents the excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed. The Company has determined that it operates in a single segment and has a single reporting unit associated with the design, development, manufacture, sale and support of high performance and reliable Solid-State Drives (“SSDs’’) and premium computer components. In September 2011, the FASB amended its guidance to simplify testing goodwill for impairment, allowing an entity to first assess qualitative factors to determine whether it is necessary to perform a two-step quantitative goodwill impairment test. If an entity determines as a result of the qualitative assessment that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the quantitative impairment test is required. Otherwise, no further testing is required. The performance of the quantitative impairment test involves a two-step process. The first step of the impairment test involves comparing the fair values of the applicable reporting unit with its aggregate carrying value, including goodwill. The Company generally determines the fair value of its reporting unit using the income approach methodology of valuation that includes the discounted cash flow method, the market approach that includes a comparative analysis of a peer group of publicly traded companies, as well as other generally accepted valuation methodologies. If the carrying amount of the reporting unit exceeds the reporting unit’s fair value, the Company performs the second step of the quantitative impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill.
	The Company performs goodwill impairment testing at the reporting unit level at least annually in the fourth fiscal quarter or more often if events or changes in circumstances indicate the carrying value may not be recoverable.
Impairment of long-lived assets	Impairment of long-lived assets
	Long-lived assets consist of property and equipment and purchased intangible assets. Purchased intangible assets from business combinations include trademarks and trade names, customer relationships, the amortization of which is charged to sales and marketing expenses, and core and developed technology, the amortization of which is charged to cost of revenue.
	The Company tests long-lived assets or asset groups for recoverability when events or changes in circumstances indicate that their carrying amounts may not be recoverable. Circumstances which could trigger a review include, but are not limited to: significant decreases in the market price of the asset; significant adverse changes in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of the asset; current period cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and current expectation that the asset will more likely than not be sold or disposed of before the end of its estimated useful life.
	Recoverability is assessed based on the carrying amounts of the asset and its fair value which is generally determined as the sum of the undiscounted cash flows expected to result from the use and the eventual disposal of the asset, as well as specific appraisals in certain instances. An impairment loss is recognized when the carrying amount is not recoverable and exceeds fair value.
Restructuring charges	Restructuring charges
	Restructuring charges include costs related to employee termination benefits and long-lived assets impaired or abandoned. The determination of when we accrue for employee termination benefits depends on whether the termination benefits are provided under a one-time benefit arrangement or under an on-going benefit arrangement. For restructuring charges recorded as an on-going benefit arrangement, a liability for post-employment benefits is recorded when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated. For restructuring charges recorded as a one-time benefit arrangement, we recognize a liability for employee termination benefits when a plan of termination, approved by management and establishing the terms of the benefit arrangement, has been communicated to employees. The timing of the recognition of one-time employee termination benefits is dependent upon the period of time the employees are required to render service after communication. If employees are not required to render service in order to receive the termination benefits or if employees will not be retained to render service beyond the minimum legal notification period, a liability for the termination benefits is recognized at the communication date. In instances where employees will be retained to render service beyond the minimum legal notification period, the liability for employee termination benefits is measured initially at the communication date based on the fair value of the liability as of the termination date and is recognized ratably over the future service period. We continually evaluate the adequacy of the remaining liabilities under our restructuring initiatives.
	Although we believe that these estimates accurately reflect the costs of our restructuring plans, actual results may differ, thereby requiring us to record additional provisions or reverse a portion of such provisions.
Income taxes	Income taxes
	The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse and for operating losses and tax credit carry forwards. The Company estimates its provision for income taxes and amounts ultimately payable or recoverable in numerous tax jurisdictions around the world. Estimates involve interpretations of regulations and are inherently complex. Resolution of income tax treatments in individual jurisdictions may not be known for many years after completion of any fiscal year. The Company is required to evaluate the realizability of its deferred tax assets on an ongoing basis to determine whether there is a need for a valuation allowance with respect to such deferred tax assets. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. Significant management judgment is required in determining any valuation allowance recorded against deferred tax assets. In evaluating the ability to recover deferred tax assets, the Company considers available positive and negative evidence giving greater weight to its recent cumulative losses and our ability to carryback losses against prior taxable income and, commensurate with objective verifiability, the forecast of future taxable income including the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies.
	The Company recognizes and measures uncertain tax positions taken or expected to be taken in a tax return if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such positions are then measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The Company adjusts these reserves in light of changing facts and circumstances, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate, as well as the related net interest. The Company recognizes interest and penalties related to unrecognized tax benefits within the other income (expense) line in the consolidated statements of operations. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheets.
	The Company files annual income tax returns in multiple taxing jurisdictions around the world. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves, as well as the related interest, in light of changing facts and circumstances. Settlement of any particular position could require the use of cash.
Fair value of financial instruments	Fair value of financial instruments
	OCZ’s financial instruments consist primarily of cash equivalents, accounts receivable, accounts payable, accrued liabilities and loans payable. The carrying value of these financial instruments approximates fair value as they are short-term to maturity. Derivative liabilities consist of common stock warrants and are classified as Level 3 liabilities under the fair value hierarchy.
	The applicable accounting guidance establishes a framework for measuring fair value and expands required disclosure about the fair value measurements of assets and liabilities. This guidance requires the Company to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a nonrecurring basis in periods subsequent to initial measurement, in a three-tier fair value hierarchy as described below.
	The guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
	Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The guidance describes three levels of inputs that may be used to measure fair value:
		•		Level 1 — Observable inputs that reflect quoted prices for identical assets or liabilities in active markets.
		•		Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		•		Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	The Company uses the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. During fiscal years 2013 and 2012, there were no nonrecurring fair value measurements of assets subsequent to initial recognition.
Revenue recognition	Revenue recognition
	The Company records product revenue net of allowances for sales returns and CIP Credits, as described below. Revenue is recognized when the following criteria have been met:
		•		There is persuasive evidence of an arrangement, generally evidenced by customer purchase orders and/or contracts;
		•		Delivery has occurred, generally upon product shipment by a common carrier when the risk of loss has passed, or the customer has waived its rights to such criteria;
		•		The terms are fixed and determinable and not subject to refund or adjustment; and
		•		Collection is reasonably assured.
	Probability of collection is assessed for each customer as it is subjected to a credit review process that evaluates the customer’s financial position, ability to pay, and the potential coverage by the Company’s credit insurer. If it is determined from the outset of an arrangement that collection is not reasonably assured, the customer generally is required to pay cash in advance of shipment. The Company also purchases credit insurance for the majority of its accounts receivable. If collectability is not considered reasonably assured from the outset of an arrangement, and the customer has not been required to pay cash in advance of shipment, the Company does not recognize revenue until collection occurs.
	The Company records allowances against revenue for various credits under customer programs:
		•		Product Returns – The Company grants limited rights to return product. Return rights vary by customer, and include stock rotation rights limited to a percentage approved by management and, in certain circumstances, the right to return defective products for credit under our warranty policy. Estimates of expected future sales returns are recognized at the time of sale based on analyses of historical return trends by customer and by product, inventories owned by and located at distributors and retailers, current customer demand, current operating conditions, product failure rates and other relevant customer and product information. Products returned are generally available for resale. Consequently, when the related product revenue is recognized, a sales return reserve is recorded along with a corresponding reduction of revenue and cost of revenue and reinstatement of the related inventory.
		•		Customer Marketing Programs – The Company issues credits for Market Development Funds under a variety of customer marketing programs with many of its distribution and retail customers, and with certain indirect partners. Allowances for Market Development Funds are made against revenue if the programs either do not have an identifiable benefit to the Company or for which the Company is unable to determine fair value. Accruals for these Marketing Development Funds are recorded at the time of sale, or time of commitment, based on negotiated terms. We provide for these programs as a reduction to revenue when the related product revenue is recorded.
		•		Rebates – Rebate programs include performance-based incentives and consumer rebates. Allowances for rebates are made based on negotiated terms, consideration of historical experience, anticipated volume of future purchases, and inventory levels of our customers.
		•		Price Protection – Certain customer agreements contain terms allowing price protection credits to be issued in the event of a subsequent price reduction, subject to limitations. An allowance for estimated price protection credits to be granted is made when the related product revenue is recorded.
	Significant management judgment must be used in estimating allowances under these programs in any accounting period. The Company regularly evaluates the adequacy of its accruals for sales returns and CIP Credits. Future market conditions and product transitions may require the Company to take action to increase such programs. In addition, when the variables used to estimate these costs change, or if actual costs differ significantly from the estimates, the Company would be required to record incremental reductions to revenue. If, at any future time, the Company becomes unable to reasonably estimate these costs, recognition of revenue is deferred until products are sold to end-users, which would adversely impact revenue recognized in the period of transition.
Research and development costs	Research and development costs
	Research and development costs are expensed as incurred.
Shipping and handling	Shipping and handling
	For the fiscal years ended February 2013, 2012 and 2011, shipping and handling costs were $4.8 million, $4.7 million and $2.9 million, respectively, and are reflected in sales and marketing expense in the Consolidated Statement of Operations.
Advertising	Advertising
	The Company engages in a variety of methods of direct advertising and marketing media which generally includes ad placement in periodicals and internet-based advertising. All of the Company’s direct advertising costs are recorded as a sales and marketing expense as incurred. Advertising costs in the fiscal years ended February 2013, 2012 and 2011 were $3.3 million, $2.3 million and $3.1 million, respectively.
Currency translation	Currency translation
	The majority of the Company’s sales are invoiced in United States Dollars (“USD”). Invoices in Euro and British Pound were insignificant during the fiscal years ended February 2013, 2012 and 2011.
	The functional currency of the Company’s Canadian, Korean and UK entities is their local currency. All of the Company’s other foreign operations use the USD as their functional currency. When the local currency is the functional currency, gains and losses from translation of these foreign currency financial statements into USD are recorded as a separate component of other comprehensive income (loss) in stockholders’ equity. For subsidiary and branch operations where the functional currency is the USD, gains and losses resulting from remeasurement of foreign currency denominated balances into USD are included in other income (expense), net. Foreign currency transaction gains and (losses) for the fiscal years ended February 2013, 2012 and 2011 were $0.5 million, $0.2 million and $41,000, respectively and were included in other income (expense), net in the accompanying Consolidated Statements of Operations.
Product warranties	Product warranties
	The Company generally warrants its products for a period of three to five years. Concurrent with the period when product revenue is recognized, a provision is recorded for the estimated warranty obligation to provide for the replacement of products or account credits for products that are found to be faulty within the warranty period. The obligation is adjusted periodically based on historical and anticipated experience.
Stock-based compensation	Stock-based compensation
	Stock-based compensation is measured based on the grant-date fair value. Fair value is estimated using the Black-Scholes model. Compensation expense for stock options is recognized on the straight-line basis over the period earned and vested. Restricted stock grants are measured based on the fair market value of the underlying stock on the date of grant and compensation expense for restricted stock grants is recognized on the straight-line basis over the requisite service period. Non-vested stock options and restricted stock grants are included in the diluted shares outstanding calculation when their effect is dilutive.
	The amount of compensation expense recognized using the Black-Scholes model requires the Company to exercise judgment and make assumptions relating to the factors that determine the fair value of stock option grants. The fair value calculated by this model is a function of several factors, including the grant price, the expected future volatility and the expected term of the option and the risk-free interest rate of return over the estimated option period. The expected term and expected future volatility of the options require judgment. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those stock options expected to vest. The Company estimates the forfeiture rate based on historical experience and to the extent the actual forfeiture rate is different from the estimate, share-based compensation expense is adjusted accordingly.
Common stock warrant liability	Common stock warrant liability
	The Company accounts for certain warrants to purchase shares of common stock which are subject to certain anti-dilution adjustments which require them to be classified as derivatives. Accordingly, upon issuance, the fair value of the common stock warrants is recorded as a common stock warrant liability with a corresponding reduction of additional paid-in capital or as a discount to the related debt instrument for which the warrants were issued. The common stock warrants are subject to remeasurement to fair value at each balance sheet date, and any fair value adjustments are recognized and included in “Revaluation to fair value of common stock warrants” in the Consolidated Statements of Operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the common stock warrants. At that time of exercise or expiration, the common stock warrant liability will be adjusted to fair value with the fair value change reflected in the Consolidated Statements of Operations and the remaining final fair value, if any, will be reclassified to additional paid-in capital.
Net loss per share	Net loss per share
	Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed giving effect to all potential dilutive common stock, including stock options, restricted stock units and common stock warrants outstanding. Diluted loss per share was based only on the weighted-average number of shares outstanding during that period as the inclusion of any common stock equivalents would have been anti-dilutive.
	A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per share is as follows (in thousands):
			Years Ended February 28/29,
			2013			2012			2011
						Restated			Restated
	Numerator:
	Net loss used in computing basic and diluted net loss per share		$	(125,786	)	$	(123,452	)	$	(33,186	)

	Net loss per share –basic and diluted		$	(1.86	)	$	(2.43	)	$	(1.16	)
	The following table sets forth the weighted-average potentially dilutive securities excluded from the computation in the table above because their effect would have been anti-dilutive:
			Years Ended February 28/29,
			2013			2012			2011
	Stock options			8,259,209			5,935,605			4,025,056

	Common stock warrants			3,457,521			3,552,521			4,389,604
	Total potentially dilutive securities			12,520,321			9,488,126			8,414,660
	All outstanding options, restricted stock units and common stock warrants are potentially dilutive securities. However, since the Company incurred net losses during each of the fiscal periods presented, all potentially dilutive securities would have been anti-dilutive and were excluded from the computation of diluted shares. Accordingly, shares used to calculate basic and diluted net loss per share were the same in each period reported.

-1	“Revenue Recognition” represents various transactions that were recognized prior to meeting the revenue recognition criteria. Adjustments were recorded to reverse the original revenue recorded, defer the original revenue recorded or provide reserves against net revenue for future product returns. Also included are adjustments to recognize the reversal of the product cost, which are recorded as reductions of cost of revenue and increases to either inventory or deferred product cost.
-2	“CIP Credits” represent Market Development Funds, rebates and price protection credits. These adjustments were made to record CIP Credits in the correct accounting period and to classify them correctly in our consolidated statements of operations.
-3	“Manufacturing and Freight” represents manufacturing and freight costs that should have been capitalized as a component of product costs but were incorrectly expensed as incurred. Adjustments were made to reduce operating expenses and increase inventory (for products on hand) and cost of revenue (for products shipped).
-4	“Goodwill and Intangibles” represents a write-off of goodwill related to prior acquisitions due to a revision to our estimated enterprise value and a revision to the estimated value of certain intangible assets.

Allocation of Purchase Price Based on Fair Value of Assets Acquired and Liabilities Assumed	The following table summarizes fair value of the assets acquired and the liabilities assumed at the date of acquisition (in thousands):
	Cash acquired		$	554
	Other current assets			170
	Fixed assets			431
	Other tangible assets acquired			216

	Existing technology			96

	Deferred tax liabilities			(499	)
	Total acquisition consideration		$	32,773
	Indication of fair value of the intangible assets acquired in connection with the Indilinx acquisition were determined using the income approach. The Company used an overall discount rate of approximately 15% to estimate the fair value of the intangible assets acquired, which was derived based on financial metrics of comparable companies operating in Indilinx’s industry. In determining the appropriate discount rates to use in valuing each of the individual intangible assets, the Company adjusted the overall discount rate giving consideration to the specific risk factors of each asset. The following methods were used to value the identified intangible assets:
		•		Existing technology: The fair value of the existing technology assets acquired was established based on their highest and best use by a market participant using the “Royalty Savings Method”. In the Royalty Savings Method, the value of an asset is estimated by capitalizing the royalties saved because the Company owns the asset. Expected cash flows were discounted at the Company’s weighted average cost of capital of 15%;
		•		In-process technology: As of the acquisition date, Indilinx was developing new versions and incremental improvements to its Barefoot product and the next generation SSD products. The in-process projects were at a stage of development that required further research and development to determine technical feasibility and commercial viability. The fair value of the in-process technology assets acquired was based on the valuation premise that the assets would be “In-Use” using a discounted cash flow model;
		•		Customer lists and related relationships: The fair value of the customer contracts and related relationships assets acquired was based on the Royalty Savings Method;
		•		Trademarks and trade names: The fair value of trade names/trademarks assets acquired was established based on the Royalty Savings Method.
	Identified intangible assets are being amortized over the following useful lives:
		•		Existing technology is estimated to have a useful life of one year;
		•		In-process technology will be amortized upon completion over its projected remaining useful life as assessed on the completion date. The majority of the in-process projects were completed by the end of fiscal 2013 with the remaining project expected to be completed in 2014;
		•		Customer contracts and related relationships are being amortized over their estimated useful life of five years;
		•		Trade names/trademarks are being amortized over their estimated useful life of ten years.
	The existing technology, patents/core technology, customer contracts, and related relationships and trade names/trademarks are amortized using the straight-line method.
	PLX
	On October 24, 2011, the Company completed the acquisition of certain assets and liabilities from PLX Technology Inc. (“PLX”) in exchange for cash consideration of $2.2 million. Pursuant to the agreement, the Company obtained a non-exclusive perpetual license related to consumer storage technology, capital equipment and assumed an approximately 40 person engineering Design Team located in Abingdon, United Kingdom. This transaction further strengthened the Company’s global research and development team and provides further access to advanced technology in an effort to accelerate solid state development, reducing the time to market for the next generation of SSD products, while also reducing development costs. The Company also incurred a total of $0.2 million of transaction costs which were primarily comprised of legal, accounting and valuation expenses and are classified as “Acquisition-Related Charges” on the Consolidated Statement of Operations for the year ended February 29, 2012.

-1	“Revenue Recognition” represents various transactions that were recognized prior to meeting the revenue recognition criteria. Adjustments were recorded to reverse the original revenue recorded, defer the original revenue recorded or provide reserves against net revenue for future product returns. Also included are adjustments to recognize the reversal of the product cost, which are recorded as reductions of cost of revenue and increases to either inventory or deferred product cost.
-2	“CIP Credits” represent Market Development Funds, rebates and price protection credits. These adjustments were made to record CIP Credits in the correct accounting period and to classify them correctly in our consolidated statements of operations.
-3	“Manufacturing and Freight” represents manufacturing and freight costs that should have been capitalized as a component of product costs but were incorrectly expensed as incurred. Adjustments were made to reduce operating expenses and increase inventory (for products on hand) and cost of revenue (for products shipped).
-4	“Goodwill and Intangibles” represents a write-off of goodwill related to prior acquisitions due to a revision to our estimated enterprise value and a revision to the estimated value of certain intangible assets.
-5	“Inventory Reserves” represents adjustments to reduce the carrying value of certain inventory items that either had been returned from customers or were being used for internal development purposes.
-6	“Accruals” represents accruals for future costs to be incurred primarily for warranty and repair obligations.
-7	“Income Taxes” represents adjustments to reflect the tax impact of the restatement adjustments noted above and to record the appropriate tax provision for each jurisdiction in which the Company operates.
-8	“Reclassifications” represents the impact of reclassifications on prior period financial statements in order to conform to the current year presentation.
-9	Includes changes in allowances for bad debts.
-10	Includes adjustments in stock-based compensation.
-11	Includes the expensing of certain prepaid assets to research and development of $1.4 million and stock-based compensation of $0.1 million, partially offset by a reduction in accounts receivable allowances of ($0.1 million).
-12	Includes the expensing of certain prepaid assets to research and development.

Warrant, additional description

If the Company consummates a financing of at least $10 million in new equity or subordinated debt prior to May 31, 2013 in which it issues shares of common stock or securities that are exercisable or convertible into shares of its common stock and the effective price per shares of common stock in that financing is less than the exercise price of the Warrant, then the exercise price of the Warrant will be reduced to equal the price per share of common stock in such financing and, as a result, the number of shares of common issuable upon exercise of the Warrant shall increase such that the product of the newly adjusted number of shares of common stock and the reduced exercise price per share will equal $1.5 million. Alternatively, if the Company consummates a financing of at least $10 million in new equity or subordinated debt prior to May 31, 2013 in which it issues shares of preferred stock or securities that are exercisable or convertible into shares of its preferred stock, then the holder of the Warrant may elect to have the Warrant convert into $1.5 million shares of the preferred stock or other securities at a price per share/security paid by the investors in the financing.
