The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the dates of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from these estimates. Significant estimates and assumptions include reserves and write-downs related to receivables and inventories, the recoverability of long-lived assets, the valuation allowance relating to the Company’s deferred taxes, the valuation of equity and derivative instruments, and debt discounts and the estimated amortization periods of upfront licensing fees received from customers. Periodically, the Company evaluates and adjusts estimates accordingly. The allowance for uncollectible accounts receivable balances amounted to $9,000 and $22,000, which are included in accounts receivable, net in the accompanying June 30, 2013 and March 31, 2013 condensed consolidated balance sheets, respectively. The reserve for excess and obsolete inventory balances amounted to $71,000 and $170,000, which are included in inventories, net in the accompanying June 30, 2013 and March 31, 2013 condensed consolidated balance sheets, respectively.

Financial instruments, including cash and cash equivalents, accounts receivable, inventory, accounts payable and accrued liabilities are carried at cost, which management believes approximates fair value due to the short-term nature of these instruments. The fair value of capital lease obligations and equipment loans approximates their carrying amounts as a market rate of interest is attached to their repayment. The Company measures the fair value of financial assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The Company uses three levels of inputs that may be used to measure fair value:

Level 1 — quoted prices in active markets for identical assets or liabilities

Level 2 — quoted prices for similar assets and liabilities in active markets or inputs that are observable

Level 3 — inputs that are unobservable (for example cash flow modeling inputs based on assumptions)

Financial liabilities measured at fair value on a recurring basis are summarized below:

Level 3 liabilities are valued using unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the derivative liabilities. For fair value measurements categorized within Level 3 of the fair value hierarchy, the Company’s accounting and finance department, who report to the Chief Financial Officer, determine its valuation policies and procedures. The development and determination of the unobservable inputs for Level 3 fair value measurements and fair value calculations are the responsibility of the Company’s accounting and finance department and are approved by the Chief Financial Officer.

Level 3 Valuation Techniques:

Level 3 financial liabilities consist of the derivative liabilities for which there is no current market for these securities such that the determination of fair value requires significant judgment or estimation. Changes in fair value measurements categorized within Level 3 of the fair value hierarchy are analyzed each period based on changes in estimates or assumptions and recorded as appropriate.

The Company uses the Black-Scholes option valuation model to value Level 3 financial liabilities at inception and on subsequent valuation dates. This model incorporates transaction details such as the Company’s stock price, contractual terms, maturity, risk free rates, as well as volatility.

A significant decrease in the volatility or a significant decrease in the Company’s stock price, in isolation, would result in a significantly lower fair value measurement. Changes in the values of the derivative liabilities are recorded in “(Loss) gain due to change in fair value of derivative instruments” in the Company’s condensed consolidated statements of comprehensive (loss) income.

As of June 30, 2013, there were no transfers in or out of Level 3 from other levels in the fair value hierarchy.

The accompanying unaudited condensed consolidated financial statements as of June 30, 2013 and for the three months then ended have been prepared in accordance with the accounting principles generally accepted in the United States of America for interim financial information and pursuant to the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission (“SEC”) and on the same basis as the Company prepares its annual audited consolidated financial statements. The unaudited condensed consolidated balance sheet as of June 30, 2013, the condensed consolidated statements of comprehensive (loss) income for the three months ended June 30, 2013 and 2012, and the condensed consolidated statements of cash flows for the three months ended June 30, 2013 and 2012 are unaudited, but include all adjustments, consisting only of normal recurring adjustments, which the Company considers necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The results for the three months ended June 30, 2013 are not necessarily indicative of results to be expected for the year ending March 31, 2014 or for any future interim period. The condensed consolidated balance sheet at March 31, 2013 has been derived from audited consolidated financial statements. However, it does not include all of the information and notes required by accounting principles generally accepted in the United States of America for complete consolidated financial statements. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements for the year ended March 31, 2013, and notes thereto included in the Company’s annual report on Form 10-K, which was filed with the SEC on June 25, 2013.

The Company classifies common stock purchase warrants and other free standing derivative financial instruments as equity if the contracts (i) require physical settlement or net-share settlement or (ii) give the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the control of the Company), (ii) give the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement), or (iii) contain reset provisions as either an asset or a liability. The Company assesses classification of its freestanding derivatives at each reporting date to determine whether a change in classification between assets and liabilities is required. The Company determined that its freestanding derivatives, which principally consist of warrants to purchase common stock, satisfied the criteria for classification as equity instruments at June 30, 2013, other than certain warrants that contain reset provisions and certain warrants that require net-cash settlement that the Company classified as derivative liabilities.

In June 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. This guidance improves the comparability, consistency and transparency of financial reporting and increases the prominence of items reported in other comprehensive income.  In December 2011, the FASB issued ASU No. 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05. ASU 2011-12 defers the requirement that companies present reclassification adjustments for each component of Accumulated Other Comprehensive Income in both net income and Other Comprehensive Income on the face of the financial statements. All other requirements in ASU No. 2011-05 are not affected by ASU No. 2011-12, including the requirement to report comprehensive income either in a single continuous financial statement or in two separate but consecutive financial statements.  While the adoption of this standard required the Company to change the format of its condensed consolidated financial statements, it did not have a material impact on the Company’s consolidated financial position and results of operations.

Accounting standards that have been issued or proposed by the FASB, SEC and/or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the condensed consolidated financial statements upon adoption.
