Summary of Significant Accounting Policies | Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include those relating to share-based compensation, and assumptions that have been used historically to value warrants and warrant modifications. With the exception of the $1.25 million of sublicense revenue recorded in the quarter ended December 31, 2016 under the BlueRock Agreement, we do not currently have, nor have we had during the periods covered by this report, any arrangements requiring the recognition of revenue. Research and Development Expenses Research and development expenses are composed of both internal and external costs. Internal costs include salaries and employment-related expenses of our scientific personnel and direct project costs. External research and development expenses consist primarily of costs associated with nonclinical and clinical development of AV-101, now in Phase 2 clinical development, initially for MDD, stem cell technology-related research and development costs, and costs related to the filing, maintenance and prosecution of patents and patent applications, technology licenses and protection of other intellectual property. All such costs are charged to expense as incurred. Stock-Based Compensation We recognize compensation cost for all stock-based awards to employees or consultants based on the grant date fair value of the award. Non-cash stock-based compensation expense is recognized over the period during which the employee or consultant is required to perform services in exchange for the award, which generally represents the scheduled vesting period. We have no awards with market or performance conditions. For equity awards to non-employees, we re-measure the fair value of the awards as they vest and the resulting change in value is recognized as an expense during the period over which the services are performed. The table below summarizes stock-based compensation expense included in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Loss for the three months ended June 30, 2017 and 2016. Three Months Ended June 30, 2017 2016 Research and development expense: Stock option grants $ 191,400 $ 44,000 191,400 44,000 General and administrative expense: Stock option grants 175,600 63,900 175,600 63,900 Total stock-based compensation expense $ 367,000 $ 107,900 In April 2017, our Board approved the grant of options to purchase an aggregate of 880,000 shares of our common stock at an exercise price of $1.96 per share to the independent members of our Board, our officers and our employees. In June 2016, our Board approved the grant of options to purchase an aggregate of 655,000 shares of our common stock at an exercise price of $3.49 per share to the independent members of our Board and to our officers, including our then-newly-hired Chief Medical Officer. We valued the options granted in April 2017 and June 2016 using the Black-Scholes Option Pricing Model and the following weighted average assumptions: Assumption: April 2017 June 2016 Market price per share at grant date $ 1.96 $ 3.49 Exercise price per share $ 1.96 $ 3.49 Risk-free interest rate 2.02 % 1.34 % Contractual or estimated term in years 6.48 6.68 Volatility 83.24 % 81.69 % Dividend rate 0.0 % 0.0 % Shares 880,000 655,000 Fair Value per share $ 1.42 $ 2.50 Comprehensive Loss We have no components of other comprehensive loss other than net loss, and accordingly our comprehensive loss is equivalent to our net loss for the periods presented. Income (Loss) per Common Share Basic net income (loss) per share of common stock excludes the effect of dilution and is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding for the period. Diluted net income (loss) per share of common stock reflects the potential dilution that could occur if securities or other contracts to issue shares of common stock were exercised or converted into shares of common stock. As a result of our net loss for the periods presented, potentially dilutive securities were excluded from the computation of net loss per share, as their effect would be antidilutive. For the three-month periods ended June 30, 2017 and 2016, the accrual for dividends on our Series B 10% Convertible Preferred Stock ( Series B Preferred Potentially dilutive securities excluded in determining diluted net loss attributable to common stockholders per common share are as follows: As of June 30, 2017 2016 Series A Preferred stock issued and outstanding (1) 750,000 750,000 Series B Preferred stock issued and outstanding (2) 1,160,240 1,247,740 Series C Preferred stock issued and outstanding (3) 2,318,012 2,318,012 Outstanding options under the Amended and Restated 2016 (formerly 2008) and 1999 Stock Incentive Plans 2,522,593 986,987 Outstanding warrants to purchase common stock 4,796,506 4,606,480 Total 11,547,351 9,909,219 ____________ (1) Assumes exchange under the terms of the October 11, 2012 Note Exchange and Purchase Agreement, as amended (2) Assumes exchange under the terms of the Certificate of Designation of the Relative Rights and Preferences of the Series B 10% Convertible Preferred Stock, effective May 5, 2015 (3) Assumes exchange under the terms of the Certificate of Designation of the Relative Rights and Preferences of the Series C Convertible Preferred Stock, effective January 25, 2016 Fair Value Measurements We do not use derivative instruments for hedging of market risks or for trading or speculative purposes. We carried no assets or liabilities at fair value at June 30, 2017 or March 31, 2017. Recent Accounting Pronouncements Except as described below, there have been no recent accounting pronouncements or changes in accounting pronouncements during the three months ended June 30, 2017, as compared to the recent accounting pronouncements described in our Form 10-K for the fiscal year ended March 31, 2017, that are of significance or potential significance to us. In February 2016, the Financial Accounting Standards Board ( FASB ASU In March 2016, the FASB issued ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting,” which simplified several aspects of the accounting for share-based payments, including immediate recognition of all excess tax benefits and deficiencies in the income statement, changing the threshold to qualify for equity classification up to the employees’ maximum statutory tax rates, allowing an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur, and clarifying the classification on the statement of cash flows for the excess tax benefit and employee taxes paid when an employer withholds shares for tax-withholding purposes. This ASU became effective for our interim and annual reporting periods beginning April 1, 2017, and the adoption of this standard did not have a material impact on our financial statements. As part of the adoption of this standard, we elected to account for the impact of option forfeitures as they occur. |
