Notes to Financial Statements
Basis of Presentation	The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Rule 8-03 of Regulation S-X. Accordingly, they do not contain all of the information and footnotes required for complete consolidated financial statements. In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly our interim financial information. The accompanying Condensed Consolidated Balance Sheet at March 31, 2016 has been derived from our audited consolidated financial statements at that date but does not include all disclosures required by U.S. GAAP. The operating results for the three months ended June 30, 2016 are not necessarily indicative of the operating results to be expected for our fiscal year ending March 31, 2017 or for any other interim period or any other future period. The accompanying unaudited Condensed Consolidated Financial Statements and notes to Condensed Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements for the fiscal year ended March 31, 2016 contained in our Annual Report on Form 10-K, as filed with the Securities and Exchange Commission (SEC) on June 24, 2016. The accompanying Condensed Consolidated Financial Statements have been prepared assuming we will continue as a going concern. As a developing-technology company having not yet developed commercial products or achieved sustainable revenues, we have experienced recurring losses and negative cash flows from operations resulting in a deficit of $133.7 million accumulated from inception through June 30, 2016. We expect losses and negative cash flows from operations to continue for the foreseeable future as we engage in further potential development of AV-101 and launch and execute our drug rescue programs and pursue potential drug development and regenerative medicine opportunities. Since our inception in May 1998 through June 30, 2016, we have financed our operations and technology acquisitions primarily through the issuance and sale of our equity and debt securities, including convertible promissory notes and short-term promissory notes, for cash proceeds of approximately $44.3 million, as well as from an aggregate of approximately $16.4 million of government research grant awards, strategic collaboration payments and other revenues. Additionally, we have issued equity securities with an approximate value at issuance of $29.1 million in non-cash settlements of certain liabilities, including liabilities for professional services rendered to us or as compensation for such services. Between April 1, 2016 and May 4, 2016, we sold to accredited investors Series B Preferred Units consisting of 39,714 unregistered shares of our Series B Preferred Stock, par value $0.001 per share (Series B Preferred), and five year warrants to purchase 39,714 shares of our common stock, from which we received cash proceeds of $278,000. Further, on May 16, 2016 we consummated an underwritten public offering pursuant to which we issued an aggregate of 2,570,040 registered shares of our common stock at the public offering price of $4.24 per share and five-year warrants to purchase up to 2,705,883 registered shares of common stock, with an exercise price of $5.30 per share, at the public offering price of $0.01 per warrant, including shares and warrants issued pursuant to the exercise of the underwriters' over-allotment option (the May 2016 Public Offering). We received net cash proceeds of approximately $9.5 million from the May 2016 Public Offering after deducting fees and expenses. We expect the proceeds of these transactions to provide sufficient cash to sustain our operations through our fiscal year ending March 31, 2017, however they will not be adequate to enable the completion of our Phase 2b clinical trial of AV-101 in MDD. Accordingly, we intend to raise additional capital through sales of our securities, which may include both debt and equity securities. We may also seek research and development collaborations that could generate revenue, as well as government grant awards. Further, strategic collaborations, such as our February 2015 CRADA with the NIMH providing for the NIMH to fund our Phase 2a study of AV-101 in MDD, may provide resources to support a portion of our future cash needs and working capital requirements. Although we may seek additional collaborations that could generate revenue, as well as new government grant awards, no assurance can be provided that any such collaborations or awards will occur in the future. Our future working capital requirements will depend on many factors, including, without limitation, the scope and nature of opportunities related to our success and the success of certain other companies in clinical trials, including our development of AV-101 as a treatment for MDD and other CNS conditions, and our stem cell technology platform, the availability of, and our ability to obtain, government grant awards and our ability to enter into collaborations on terms acceptable to us. To further advance the clinical development of AV-101 and our stem cell technology platform, as well as support our operating activities, we plan to continue to carefully manage our routine operating costs, including our employee headcount and related expenses, as well as costs relating to regulatory consulting, contract research and development, investor relations and corporate development, legal, accounting, public company compliance and other professional services and working capital costs. Notwithstanding the foregoing, substantial additional financing may not be available to us on a timely basis, on acceptable terms, or at all. If we are unable to obtain substantial additional financing on a timely basis in the near term, our business, financial condition, and results of operations may be harmed, the price of our stock may decline, we may be required to reduce, defer, or discontinue certain of our research and development activities and we may not be able to continue as a going concern. These Condensed Consolidated Financial Statements do not include any adjustments that might result from the outcome of this uncertainty.
