The Company	1. The Company MEI Pharma, Inc., or “the Company”, is an oncology company focused on the clinical development of novel therapies for cancer. The Company’s common stock is listed on the Nasdaq Capital Market under the symbol “MEIP”. The Company’s business purpose is the development of drugs for the treatment of cancer. The Company’s portfolio of clinical drug candidates includes Pracinostat, an orally available histone deacetylase (“HDAC”) inhibitor currently in Phase II clinical trials for the treatment of advanced hematologic diseases such as acute myeloid leukemia (“AML”) and myelodysplastic syndrome (“MDS”). In August 2012, the Company completed the acquisition of certain assets and intellectual property, including those related to Pracinostat, from SBio Pte Ltd (“SBio”). The Company’s clinical development pipeline also includes ME-344, an isoflavone-based mitochondrial inhibitor that showed clinical evidence of activity in a Phase I dose-escalation study in refractory solid tumors. The Company is also developing PWT143, an oral inhibitor of phosphatidylinositide 3-kinase (“PI3K”) delta. The Company recently completed a first-in-human, single ascending dose study of PWT143. The Company owns exclusive worldwide rights to all of its drug candidates, including Pracinostat, ME-344 and PWT143. Basis of Presentation The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the accompanying financial statements do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the accompanying financial statements reflect all adjustments (consisting of normal recurring adjustments) that are necessary for a fair statement of the financial position, results of operations and cash flows for the periods presented. The Company has evaluated subsequent events through the date the financial statements were issued. The accompanying unaudited financial statements should be read in conjunction with the audited financial statements and notes thereto as of and for the fiscal year ended June 30, 2015, included in the Company’s Annual Report on Form 10-K (“2015 Annual Report”) filed with the Securities and Exchange Commission (“SEC”) on September 2, 2015. Interim results are not necessarily indicative of results for a full year. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and disclosures made in the accompanying notes to the financial statements. The Company uses estimates that affect the reported amounts (including assets, liabilities, revenues and expenses) and related disclosures. Actual results could materially differ from those estimates. Significant Accounting Policies On July 1, 2015, we changed our method of estimating the grant date fair value for stock options from a binomial valuation model to a Black-Scholes valuation model. The change was made as a result of the implementation of new accounting software. The overall result from applying either the Black-Scholes or binomial valuation model did not result in a material difference in the stock option valuation. Other than this change, there have been no changes in our significant accounting policies during the three months ended September 30, 2015 as compared to the significant accounting policies described in our 2015 Annual Report. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). In August 2015, the FASB issued ASU 2015-14 which defers the effective date of this standard by one year to annual reporting periods beginning after December 15, 2017, including interim periods within that year. Early adoption of ASU 2014-09 is permitted but not before the original effective date (annual periods beginning after December 15, 2016). Currently the Company is not generating any revenue. Therefore, we have not yet determined the transition method by which we will adopt the standard. In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). The standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued and provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. Certain disclosures will be required if conditions give rise to substantial doubt about an entity’s ability to continue as a going concern. ASU 2014-15 applies to all entities and is effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. Subsequent to adoption, the Company will apply the guidance in ASU 2014-15 to assess its ability to continue as a going concern.
