Use of Estimates

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 tax assets, valuation of equity and derivative instruments, debt discounts, valuation of investments, and the estimated amortization periods of upfront product licensing fees received from customers. Periodically, the Company evaluates and adjusts estimates accordingly. The allowances for uncollectible accounts receivable balances amounted to $19,000 and $8,000, which are included in Accounts Receivable, net in the accompanying September 30, 2014 and March 31, 2014 condensed consolidated balance sheets, respectively.

Net Loss per Share

The Company computes basic net loss per share by dividing net loss per share available to common stockholders by the weighted average number of common shares outstanding for the period and excludes the effects of any potentially dilutive securities. Diluted earnings per share, if presented, would include the dilution that would occur upon the exercise or conversion of all potentially dilutive securities into common stock using the “treasury stock” and/or “if converted” methods as applicable. The computation of basic loss per share for the three and six months ended September 30, 2014 and 2013 excludes the potentially dilutive securities summarized in the table below because their inclusion would be anti-dilutive.

Common Stock Purchase Warrants and Other Derivative Financial Instruments

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, other than certain warrants that contained reset provisions and certain warrants that required net-cash settlement that the Company classified as derivative liabilities as more fully described in Note 5.

Revenue Recognition and Accounts Receivable

The Company generates revenue from sales of our products to hospitals, medical centers, doctors, pharmacies, and distributors. The Company sells our products directly to third parties and to distributors through various cancelable distribution agreements. The Company also entered into agreements to license our technology and products.

The Company also provides regulatory compliance testing and quality assurance services to medical device and pharmaceutical companies.

The Company records revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) the fee is fixed or determinable, and (iv) collectability of the sale is reasonably assured.

The Company requires all of our product sales to be supported by evidence of a sale transaction that clearly indicates the selling price to the customer, shipping terms and payment terms. Evidence of an arrangement generally consists of a contract or purchase order approved by the customer. The Company has ongoing relationships with certain customers from which it customarily accepts orders by telephone in lieu of purchase orders.

The Company recognizes revenue at the time in which we receive confirmation that the goods were either tendered at their destination, when shipped “FOB destination,” or transferred to a shipping agent, when shipped “FOB shipping point.” Delivery to the customer is deemed to have occurred when the customer takes title to the product. Generally, title passes to the customer upon shipment, but could occur when the customer receives the product based on the terms of the agreement with the customer.

The selling prices of all goods are fixed, and agreed to with the customer, prior to shipment. Selling prices are generally based on established list prices. The Company does not customarily permit our customers to return any products for monetary refunds or credit against completed or future sales. The Company may, from time to time, replace expired goods on a discretionary basis. The Company records these types of adjustments, when made, as a reduction of revenue. Sales adjustments were insignificant during the quarters ended September 30, 2014 and 2013 and the years ended March 31, 2014 and 2013.

The Company evaluates the creditworthiness of new customers and monitor the creditworthiness of our existing customers to determine whether events or changes in their financial circumstances would raise doubt as to the collectability of a sale at the time in which a sale is made. Payment terms on sales made in the United States are generally 30 days and internationally, generally range from 30 days to 90 days.

In the event a sale is made to a customer under circumstances in which collectability is not reasonably assured, the Company either requires the customer to remit payment prior to shipment or defers recognition of the revenue until payment is received. The Company maintains a reserve for amounts which may not be collectible due to risk of credit losses.

Additionally, the Company defers recognition of revenue related to distributors’ that are unable to provide inventory or product sell-through reports on a timely basis, until payment is received. The Company believes the receipt of payment is the best indication of product sell-through.

The Company has entered into distribution agreements in Europe, Mexico, and certain other countries. Recognition of revenue and related cost of revenue from product sales is deferred until the product is sold from the distributors to their customers.

When the Company receives letters of credit and the terms of the sale provide for no right of return except to replace defective product, revenue is recognized when the letter of credit becomes effective and the product is shipped.

Product license revenue is generated through agreements with strategic partners for the commercialization of Microcyn® products. The terms of the agreements sometimes include non-refundable upfront fees. The Company analyzes multiple element arrangements to determine whether the elements can be separated. Analysis is performed at the inception of the arrangement and as each product is delivered. If a product or service is not separable, the combined deliverables are accounted for as a single unit of accounting and recognized over the performance obligation period.

Assuming the elements meet the criteria for separation and all other revenue requirements for recognition, the revenue recognition methodology prescribed for each unit of accounting is summarized below:

When appropriate, the Company defers recognition of non-refundable upfront fees. If the Company has continuing performance obligations then such up-front fees are deferred and recognized over the period of continuing involvement.

The Company recognizes royalty revenues from licensed products upon the sale of the related products.

Revenue from consulting contracts is recognized as services are provided. Revenue from testing contracts is recognized as tests are completed and a final report is sent to the customer.

Inventory

Inventories are stated at the lower of cost, cost being determined on a standard cost basis (which approximates actual cost on a first-in, first-out basis), or market.  Due to changing market conditions, estimated future requirements, age of the inventories on hand and production of new products, the Company regularly reviews inventory quantities on hand and record a provision to write down excess and obsolete inventory to its estimated net realizable value.

Income Taxes

The Company is required to determine the aggregate amount of income tax expense or loss based upon tax statutes in jurisdictions in which it conducts business. In making these estimates, the Company adjusts its results determined in accordance with generally accepted accounting principles for items that are treated differently by the applicable taxing authorities. Deferred tax assets and liabilities resulting from these differences are reflected on its balance sheet for temporary differences in loss and credit carryforwards that will reverse in subsequent years. The Company also establishes a valuation allowance against deferred tax assets when it is more likely than not that some or all of the deferred tax assets will not be realized. Valuation allowances are based, in part, on predictions that management must make as to the results in future periods. The outcome of events could differ over time which would require that the Company makes changes in its valuation allowance.

Fair Value of Financial Assets and Liabilities

Financial instruments, including cash and cash equivalents, accounts receivable, 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 carrying amounts of long-term investments include the investment held in Ruthigen, Inc. (“Ruthigen”) and are carried at cost, which management believes approximates fair value. 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; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.

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 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.

As of September 30, 2014, there were no transfers in or out of Level 3 from other levels in the fair value hierarchy.

Impairment of Long-Lived Assets

The Company periodically reviews the carrying values of its long-lived assets when events or changes in circumstances would indicate that it is more likely than not that their carrying values may exceed their realizable values, and records impairment charges when considered necessary. Specific potential indicators of impairment include, but are not necessarily limited to:

When circumstances indicate that an impairment may have occurred, the Company tests such assets for recoverability by comparing the estimated undiscounted future cash flows expected to result from the use of such assets and their eventual disposition to their carrying amounts. In estimating these future cash flows, assets and liabilities are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows generated by other such groups. If the undiscounted future cash flows are less than the carrying amount of the asset, an impairment loss, measured as the excess of the carrying value of the asset over its estimated fair value, will be recognized. The cash flow estimates used in such calculations are based on estimates and assumptions, using all available information that management believes is reasonable. During the six months ended September 30, 2014, the Company had noted no indicators of impairment.

Long-Term Investments

The Company’s long-term investments consist of the 2,000,000 shares it owns in Ruthigen at September 30, 2014 and March 31, 2014. The Company has accounted for the 2,000,000 shares of common stock it owns in Ruthigen at cost in accordance with ASC 325-20 as a result of (a) the restrictions on voting the shares held as disclosed above, (b) the Company having no representation on the Ruthigen Board of Directors, (c) the Company’s inability to set policy at Ruthigen (d) the Company having no further commitments for funding the operations of Ruthigen and (e) the restrictions on transferability of the shares which extend beyond a one-year period. The Company reviewed available public information disclosed by Ruthigen to determine if operational issues could be identified that would result in a decline in the value of the Ruthigen investment. The Company did not identify any operational issues that would negatively impact the value of the investment. The Company has not recorded any impairment losses during the three or six months ended September 30, 2014 as it relates to its investments held.

Subsequent Events

Management has evaluated subsequent events or transactions occurring through the date the condensed consolidated financial statements were issued (Note 12).

Recent Accounting Pronouncements

The Financial Accounting Standards Board (“FASB”) has issued Accounting Standards Update (“ASU”) No. 2014-12, Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period . This ASU requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered.. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s condensed consolidated financial position and results of operations.

The FASB has issued ASU No. 2014-09, Revenue from Contracts with Customers. This ASU supersedes the revenue recognition requirements in Accounting Standards Codification 605 - Revenue Recognition and most industry-specific guidance throughout the Codification. The standard requires that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. This ASU is effective on January 1, 2017 and should be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the ASU recognized at the date of initial application. The Company is currently evaluating the impact of the adoption of this standard on its condensed consolidated financial position and results of operations.

The FASB has issued ASU No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The guidance, which is effective for annual reporting periods ending after December 15, 2016, extends the responsibility for performing the going-concern assessment to management and contains guidance on how to perform a going-concern assessment and when going-concern disclosures would be required under U.S. GAAP.  The Company has elected to early adopt the provisions of ASU 2014-15 in connection with the issuance of these unaudited condensed consolidated financial statements.  Management’s evaluations of events and conditions that raise substantial doubt regarding the Company’s ability to continue as a going concern have been disclosed in Note 2.

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.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Aquamed Technologies, Inc. (“Aquamed”), Oculus Technologies of Mexico S.A. de C.V. (“OTM”), Oculus Innovative Sciences Netherlands, B.V. (“OIS Europe”) and Ruthigen (through the date of deconsolidation on March 26, 2014). Aquamed has no current operations. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of 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 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 tax assets, valuation of equity and derivative instruments, debt discounts, valuation of investments, and the estimated amortization periods of upfront product licensing fees received from customers.

Revenue Recognition

The Company generates revenue from sales of its products to hospitals, medical centers, doctors, pharmacies, and distributors. The Company sells its products directly to third parties and to distributors through various cancelable distribution agreements. The Company has also entered into agreements to license its technology and its products.

The Company also provides regulatory compliance testing and quality assurance services to medical device and pharmaceutical companies.

The Company records revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) the fee is fixed or determinable, and (iv) collectability of the sale is reasonably assured.

The Company requires all of its product sales to be supported by evidence of a sale transaction that clearly indicates the selling price to the customer, shipping terms and payment terms. Evidence of an arrangement generally consists of a contract or purchase order approved by the customer. The Company has ongoing relationships with certain customers from which it customarily accepts orders by telephone in lieu of purchase orders.

The Company recognizes revenue at the time it receives a confirmation that the goods were either tendered at their destination, when shipped “FOB destination,” or transferred to a shipping agent, when shipped “FOB shipping point.” Delivery to the customer is deemed to have occurred when the customer takes title to the product. Generally, title passes to the customer upon shipment, but could occur when the customer receives the product based on the terms of the agreement with the customer.

The selling prices of all goods that the Company sells are fixed, and agreed to with the customer, prior to shipment. Selling prices are generally based on established list prices. The Company does not customarily permit its customers to return any of its products for monetary refunds or credit against completed or future sales. The Company, from time to time, may replace expired goods on a discretionary basis. The Company records these types of adjustments, when made, as a reduction of revenue. Sales adjustments were insignificant during the years ended March 31, 2014 and 2013.

The Company evaluates the creditworthiness of new customers and monitors the creditworthiness of its existing customers to determine whether events or changes in their financial circumstances would raise doubt as to the collectability of a sale at the time in which a sale is made. Payment terms on sales made in the United States are generally 30 days and internationally, generally range from 30 days to 90 days.

In the event a sale is made to a customer under circumstances in which collectability is not reasonably assured, the Company either requires the customer to remit payment prior to shipment or defers recognition of the revenue until payment is received. The Company maintains a reserve for amounts which may not be collectible due to risk of credit losses.

Additionally, the Company’s treatment for recognizing revenue related to distributors that are unable to provide inventory or product sell-through reports on a timely basis, is to defer and recognize revenue when payment is received. The Company believes the receipt of payment is the best indication of product sell-through.

The Company has entered into distribution agreements in Europe. Recognition of revenue and related cost of revenue from product sales is deferred until the product is sold from the distributors to their customers. 

When the Company receives letters of credit and the terms of the sale provide for no right of return except to replace defective product, revenue is recognized when the letter of credit becomes effective and the product is shipped.

Product license revenue is generated through agreements with strategic partners for the commercialization of Microcyn® products. The terms of the agreements sometimes include non-refundable upfront fees. The Company analyzes multiple element arrangements to determine whether the elements can be separated. Analysis is performed at the inception of the arrangement and as each product is delivered. If a product or service is not separable, the combined deliverables are accounted for as a single unit of accounting and recognized over the performance obligation period.

When appropriate, the Company defers recognition of non-refundable upfront fees. If it has continuing performance obligations then such up-front fees are deferred and recognized over the period of continuing involvement.

The Company recognizes royalty revenues from licensed products upon the sale of the related products.

Revenue from consulting contracts is recognized as services are provided. Revenue from testing contracts is recognized as tests are completed and a final report is sent to the customer.

Sales Tax and Value Added Taxes

The Company accounts for sales taxes and value added taxes imposed on its goods and services on a net basis.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash equivalents may be invested in money market funds, commercial paper, variable rate demand instruments, and certificates of deposits.

Long-Term Investments

The Company’s long-term investments consist of the 2,000,000 shares it owns in Ruthigen at March 31, 2014. The Company carries securities that do not have a readily determinable fair value at cost. The Company has not recorded any impairment losses during the years ended March 31, 2014 as it relates to its investments held.

Concentration of Credit Risk and Major Customers

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash, cash equivalents and accounts receivable. Cash and cash equivalents are maintained in financial institutions in the United States, Mexico and the Netherlands. The Company is exposed to credit risk in the event of default by these financial institutions for amounts in excess of the Federal Deposit Insurance Corporation insured limits. Cash and cash equivalents held in foreign banks are intentionally kept at minimal levels, and therefore have minimal credit risk associated with them.

The Company grants credit to its business customers, which are primarily located in Mexico, Europe and the United States. Collateral is generally not required for trade receivables. The Company maintains allowances for potential credit losses. At March 31, 2014, one customer represented 44%, one customer represented 15%, and one customer represented 12% of the net accounts receivable balance. During the year ended March 31, 2014, one customer represented 38%, and one customer represented 23%, respectively, of net revenues. At March 31, 2013, one customer represented 34%, one customer represented 26%, and one customer represented 15% of the net accounts receivable balance. During the year ended March 31, 2013, one customer represented 25%, and one customer represented 13%, respectively, of net revenues.

Accounts Receivable

Trade accounts receivable are recorded net of allowances for cash discounts for prompt payment, doubtful accounts, and sales returns. Estimates for cash discounts and sales returns are based on analysis of contractual terms and historical trends.

The Company’s policy is to reserve for uncollectible accounts based on its best estimate of the amount of probable credit losses in its existing accounts receivable. The Company periodically reviews its accounts receivable to determine whether an allowance for doubtful accounts is necessary based on an analysis of past due accounts and other factors that may indicate that the realization of an account may be in doubt. Other factors that the Company considers include its existing contractual obligations, historical payment patterns of its customers and individual customer circumstances, an analysis of days sales outstanding by customer and geographic region, and a review of the local economic environment and its potential impact on government funding and reimbursement practices. Account balances deemed to be uncollectible are charged to the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The allowance for doubtful accounts at March 31, 2014 and 2013 represents probable credit losses in the amounts of $8,000 and $22,000, respectively. 

Inventories

Inventories are stated at the lower of cost, cost being determined on a standard cost basis (which approximates actual cost on a first-in, first-out basis), or market.

Due to changing market conditions, estimated future requirements, age of the inventories on hand and production of new products, the Company regularly reviews inventory quantities on hand and records a provision to write down excess and obsolete inventory to its estimated net realizable value. The Company recorded reserves to reduce the carrying amounts of inventories to their net realizable value in the amounts of $47,000 and $170,000 at March 31, 2014 and 2013, respectively, which is included in cost of product revenues on the Company’s accompanying consolidated statements of comprehensive income (loss).

Fair Value of Financial Assets and Liabilities

Financial instruments, including cash and cash equivalents, accounts receivable, 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 carrying amounts of long-term investments include the investment in Ruthigen and are carried at cost, which management believes approximates fair value. 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; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.

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 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 derivatives 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 due to change in fair value of derivative liabilities” in the Company’s consolidated statements of comprehensive income (loss).

As of March 31, 2014, there were no transfers in or out of Level 3 from other levels in the fair value hierarchy.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives of the respective assets. Depreciation of leasehold improvements is computed using the straight-line method over the lesser of the estimated useful life of the improvement or the remaining term of the lease. Estimated useful asset life by classification is as follows:

Upon retirement or sale, the cost and related accumulated depreciation are removed from the consolidated balance sheet and the resulting gain or loss is reflected in operations. Maintenance and repairs are charged to operations as incurred.

Impairment of Long-Lived Assets

The Company periodically reviews the carrying values of its long-lived assets when events or changes in circumstances would indicate that it is more likely than not that their carrying values may exceed their realizable values, and records impairment charges when considered necessary. Specific potential indicators of impairment include, but are not necessarily limited to:

When circumstances indicate that an impairment may have occurred, the Company tests such assets for recoverability by comparing the estimated undiscounted future cash flows expected to result from the use of such assets and their eventual disposition to their carrying amounts. In estimating these future cash flows, assets and liabilities are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows generated by other such groups. If the undiscounted future cash flows are less than the carrying amount of the asset, an impairment loss, measured as the excess of the carrying value of the asset over its estimated fair value, will be recognized. The cash flow estimates used in such calculations are based on estimates and assumptions, using all available information that management believes is reasonable.  During the years ended March 31, 2014 and 2013, the Company had noted no indicators of impairment.

Research and Development

Research and development expense is charged to operations as incurred and consists primarily of personnel expenses, clinical and regulatory services and supplies. For the years ended March 31, 2014 and 2013, research and development expense amounted to $2,887,000 and $2,223,000, respectively.

Advertising Costs

Advertising costs are expensed as incurred. Advertising costs amounted to $155,000 and $91,000, for the years ended March 31, 2014 and 2013, respectively. Advertising costs are included in selling, general and administrative expenses in the accompanying consolidated statements of comprehensive income (loss).

Shipping and Handling Costs

The Company classifies amounts billed to customers related to shipping and handling in sale transactions as product revenues. Shipping and handling costs incurred are recorded in cost of product revenues. For the years ended March 31, 2014 and 2013, the Company recorded revenue related to shipping and handling costs of $58,000 and $116,000, respectively.

Foreign Currency Reporting

The Company’s subsidiary, OTM, uses the local currency (Mexican Pesos) as its functional currency and its subsidiary, OIS Europe, uses the local currency (Euro) as its functional currency. Assets and liabilities are translated at exchange rates in effect at the balance sheet date, and revenue and expense accounts are translated at average exchange rates during the period. Resulting translation adjustments were recorded in accumulated other comprehensive loss in the accompanying consolidated balance sheets at March 31, 2014 and 2013.

Foreign currency transaction gains (losses) relate primarily to trade payables and receivables between subsidiaries OTM and OIS Europe. These transactions are expected to be settled in the foreseeable future. The Company recorded foreign currency transaction gains of $6,000 and losses of $11,000 for the years ended March 31, 2014 and 2013, respectively. The related gains were recorded in other expense, net, in the accompanying consolidated statements of comprehensive income (loss).

Stock-Based Compensation

The Company accounts for share-based awards exchanged for employee services at the estimated grant date fair value of the award. The Company estimates the fair value of employee stock awards using the Black-Scholes option pricing model. The Company amortizes the fair value of employee stock options on a straight-line basis over the requisite service period of the awards.  Compensation expense includes the impact of an estimate for forfeitures for all stock options.

The Company accounts for equity instruments issued to non-employees at their fair value on the measurement date. The measurement of stock-based compensation is subject to periodic adjustment as the underlying equity instrument vests or becomes non-forfeitable. Non-employee stock-based compensation charges are amortized over the vesting period or as earned.

Income Taxes

Deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and net operating loss and credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to impact taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.

Tax benefits claimed or expected to be claimed on a tax return are recorded in the Company’s consolidated financial statements. A tax benefit from an uncertain tax position is only recognized 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 financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. Uncertain tax positions have had no impact on the Company’s consolidated financial condition, results of comprehensive loss or cash flows.

Comprehensive Loss

Other comprehensive loss includes all changes in stockholders’ equity during a period from non-owner sources and is reported in the consolidated statement of changes in stockholders’ equity. To date, other comprehensive loss consists of changes in accumulated foreign currency translation adjustments. Accumulated other comprehensive losses at March 31, 2014 and 2013 were $3,069,000 and $2,991,000, respectively.

Earnings (Loss) Per Share

Basic earnings and loss per share are computed by dividing the net income or loss available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options (using the treasury stock method) and warrants (using the if-converted method). Diluted loss per share excludes the shares issuable upon the exercise of stock options and warrants from the calculation of net loss per share as their effect would be anti-dilutive.

Common Stock Purchase Warrants and Other Derivative Financial Instruments

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, other than certain warrants that contained reset provisions and certain warrants that required net-cash settlement that the Company classified as derivative liabilities as more fully described in Note 11.

Preferred Stock

The Company applies the accounting standards for distinguishing liabilities from equity when determining the classification and measurement of its preferred stock. Shares that are subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. The Company classifies conditionally redeemable preferred shares, which includes preferred shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control, as temporary equity. At all other times, preferred shares are classified as stockholders' equity.

Convertible Instruments

The Company evaluates and bifurcates conversion options from their host instruments and accounts for them as free standing derivative financial instruments according to certain criteria. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument. An exception to this rule is when the host instrument is deemed to be conventional as that term is described under applicable Generally Accepted Accounting Principles (“GAAP”).
