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, determination of the relative selling prices of the components sold to Invekra, and the estimated amortization periods of upfront product licensing fees received from customers. Periodically, the Company evaluates and adjusts estimates accordingly. The allowance for doubtful accounts represents probable credit losses of $13,000 and $14,000 at December 31, 2017 and March 31, 2017, respectively. Additionally, at December 31, 2017 and March 31, 2017 the Company has allowances of $1,423,000 and $672,000, respectively, related to potential discounts, returns, distributor fees and rebates. The allowances are included in Accounts Receivable, net in the accompanying condensed consolidated balance sheets.

Basic and Diluted Net Income (Loss) per common share

Basic earnings and loss per share for both continuing and discontinued operations 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.

The following securities were excluded from the weighted average dilutive common shares outstanding because their inclusion would have been antidilutive.

Revenue Recognition and Accounts Receivable

The Company generates revenue from sales of its products to a customer base including hospitals, medical centers, doctors, pharmacies, distributors and wholesalers. The Company sells products directly to end users and to distributors. The Company also has entered into agreements to license its 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 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 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 right to return product is customarily based on the terms of the agreement with the customer. The Company estimates and accrues for potential returns and records this as a reduction of revenue in the same period the related revenue is recognized. Additionally, distribution fees are paid to certain wholesale distributors based on contractually determined rates. The Company estimates and accrues the fee on shipment to the respective wholesale distributors and recognizes the fee as a reduction of revenue in the same period the related revenue is recognized. The Company also offers cash discounts to certain customers, generally 2% of the sales price, as an incentive for prompt payment. The Company accounts for cash discounts by reducing accounts receivable by the prompt pay discount amount and recognizes the discount as a reduction of revenue in the same period the related revenue is recognized. Additionally, the Company participates in certain rebate programs which provide discounted prescriptions to qualified patients. The Company contracts with a third-party to administer the program. The Company estimates and accrues for future rebates based on historical data for rebate redemption rates and the historical value of redemptions. Rebates are recognized as a reduction of revenue in the same period the related revenue is recognized.

The Company evaluates the creditworthiness of new customers and monitors the creditworthiness of its existing customers to determine whether an event 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 to 60 days and are extended up to 90 days for initial product launches, payment terms internationally generally range from prepaid prior to shipment 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.

In the event a sale is made to a customer under circumstances in which returns cannot be estimated, the Company defers recognition of the revenue until sell-through is confirmed.

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 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.

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 net realizable value.

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 $201,000 and $61,000 at December 31, 2017 and March 31, 2017, respectively.

Reclassifications

Certain prior period amounts have been reclassified for comparative purposes to conform to the fiscal 2018 presentation. These reclassifications have no impact on the Company’s previously reported condensed consolidated net loss.

Subsequent Events

The Company evaluates events that have occurred after the balance sheet date but before the financial statements are issued. Based upon the evaluation, the Company did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the condensed consolidated financial statements (Note 11).

Adoption of Recent Accounting Standards

In March 2016 the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This update simplifies the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows.

On April 1, 2017, the Company adopted ASU No. 2016-09. As a result of adopting ASU No. 2016-09, the Company has made an accounting policy election to account for forfeitures as they occur. This change has been applied on a modified retrospective basis, with no material impacts on the Company’s financial statements. The adoption of ASU No. 2016-09 also requires excess tax benefits and tax deficiencies be recorded in the income statement as opposed to additional paid-in capital when the awards vest or are settled and recognize all previously unrecognized excess tax benefits and tax deficiencies upon adoption as a cumulative-effect adjustment to retained earnings. As of April 1, 2017, the Company recognized excess tax benefit of approximately $533,000 as an increase to deferred tax assets. However, the entire amount was offset by a full valuation allowance.  Accordingly, no cumulative-effect adjustment to retained earnings was recorded as of December 31, 2017.

Additionally, the adoption of ASU No. 2016-09 related to the accounting for minimum statutory withholding tax requirements and cash paid by an employer when directly withholding shares for tax-withholding purposes had no impact on the Company's current consolidated financial statements or on any prior period financial statements presented.

Recent Accounting Standards

Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) which supersedes FASB ASC Topic 840, Leases (Topic 840) and provides principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The FASB has continued to clarify this guidance and most recently issued ASU 2017-13 Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than twelve months regardless of classification. Leases with a term of twelve months or less will be accounted for similar to existing guidance for operating leases. The standard will be effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted upon issuance. The Company is currently evaluating the impact that ASU 2016-02 will have on its consolidated financial statements and related disclosures.

Revenue

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 amends the guidance for revenue recognition to replace numerous, industry-specific requirements and converges areas under this topic with those of the International Financial Reporting Standards. The ASU implements a five-step process for customer contract revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards. The amendment also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. Other major provisions include the capitalization and amortization of certain contract costs, ensuring the time value of money is considered in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The amendments of ASU 2014-09 were effective for reporting periods beginning after December 15, 2016, with early adoption prohibited. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. In August 2015, the FASB issued ASU 2015-14 Revenue from Contracts with Customers (Topic 606), Deferral of the Effective Date, which defers by one year the effective date of ASU 2014-09. Accordingly, this guidance is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted for interim and annual periods beginning after December 15, 2016. In March 2016, the FASB issued ASU 2016-08 Principal versus Agent Considerations (Reporting Revenue Gross versus Net) which finalizes its amendments to the guidance in the new revenue standard on assessing whether an entity is a principal or an agent in a revenue transaction. This conclusion impacts whether an entity reports revenue on a gross or net basis. In April 2016, the FASB issued ASU 2016-10 Identifying Performance Obligations and Licensing, which finalizes its amendments to the guidance in the new revenue standard regarding the identification of performance obligations and accounting for the license of intellectual property. In May 2016, the FASB issued ASU 2016-12 Narrow-Scope Improvements and Practical Expedients, which finalizes its amendments to the guidance in the new revenue standard on collectability, noncash consideration, presentation of sales tax, and transition. In December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which continues the FASB’s ongoing project to issue technical corrections and improvements to clarify the codification or correct unintended applications of guidance. In September 2017, the FASB issued ASU 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842), which provides additional implementation guidance on the previously issued ASU 2014-09. The amendments are intended to make the guidance more operable and lead to more consistent application. The amendments have the same effective date and transition requirements as the new revenue recognition standard. The Company will adopt the new standard on April 1, 2018 and currently plans to use the modified retrospective method. The majority of the Company’s business is ship and bill and, on that primary revenue stream, the Company does not expect significant differences. However, the Company’s analysis is preliminary and subject to change. The Company has not completed its assessment of multiple element arrangements and certain discount and trade promotion programs.

Business Combinations

In January 2017, the FASB issued an ASU 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business. The amendments in this Update is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company is currently evaluating the impact of adopting this guidance.

Stock Compensation

In May 2017, the FASB issued ASU No. 2017-09, Compensation–Stock Compensation (Topic 718): Scope of Modification Accounting, clarifying when a change to the terms or conditions of a share-based payment award must be accounted for as a modification. The new guidance requires modification accounting if the fair value, vesting condition or the classification of the award is not the same immediately before and after a change to the terms and conditions of the award. The new guidance is effective for the Company on a prospective basis beginning on April 1, 2018, with early adoption permitted. The Company is currently evaluating the impact that ASU 2017-09 will have on its consolidated financial statements and related disclosures.

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