Basis of Presentation, Liquidity and Summary of Significant Accounting Policies [Abstract]

Principles of consolidation – All material intercompany accounts and transactions have been eliminated in consolidation. BioTime consolidated ReCyte Therapeutics, Inc. (“ReCyte”), OncoCyte Corporation (“OncoCyte”), OrthoCyte Corporation (“OrthoCyte”), ES Cell International, Pte Ltd (“ESI”), Cell Cure Neurosciences, Ltd (“Cell Cure Neurosciences”) BioTime Asia, Limited (“BioTime Asia”), LifeMap Sciences, Inc. (“LifeMap Sciences”), LifeMap Sciences, Ltd., and LifeMap Solutions, Inc., as BioTime has the ability to control their operating and financial decisions and policies through its ownership, and the non-controlling interest of the subsidiaries that are not wholly-owned is reflected as a separate element of shareholders' equity on BioTime’s condensed consolidated balance sheets. Effective May 13, 2016, BioTime deconsolidated Asterias’ financial statements (see Notes 3 and 4).

Equity method investment in Asterias, at fair value

Equity method investment in Asterias, at fair value – BioTime uses the equity method of accounting when it has the ability to exercise significant influence, but not control, as determined in accordance with GAAP, over the operating and financial policies of the company. For equity method investments which BioTime has elected to measure at fair value, unrealized gains and losses are reported in the consolidated statements of operations as a non-operating gain or loss from equity method investment.

As further discussed in Notes 3 and 4, effective May 13, 2016, BioTime owned approximately 49% of the outstanding common stock of Asterias and has elected to account for its investment in Asterias at fair value using the equity method of accounting because since that date BioTime experienced a loss of control of Asterias, as defined by GAAP, but continues to exercise significant influence over Asterias. Under the fair value method, the investment is marked to market using the closing price of Asterias common stock on the NYSE MKT multiplied by the number of shares of Asterias held by BioTime, with changes in the fair value of the Asterias investment included in other income/expenses, net, in the condensed consolidated statements of operations. The Asterias equity method investment is considered a level 1 asset as defined by Accounting Standards Codification, or ASC 820, Fair Value Measurements and Disclosures.

Liquidity

Liquidity – Since inception, BioTime has incurred significant operating losses and has funded its operations primarily through the issuance of equity securities, payments from research grants, royalties from product sales and sales of research products and services. At June 30, 2016, BioTime had an accumulated deficit of approximately $221.7 million, working capital of $23.6 million and shareholders’ equity of $94.1 million. On June 21, 2016, and July 5, 2016, BioTime completed an equity financing and raised $18.9 million in net proceeds after discounts, commissions and other expenses (see Note 10). BioTime has evaluated its projected cash flows for it and its subsidiaries and believes that its cash and cash equivalents and available for sale securities of $28.3 million as of June 30, 2016, will be sufficient to fund its operations through the next twelve months. BioTime’s projected cash flows are subject to various risks and uncertainties. For example, clinical trials being conducted by Cell Cure Neurosciences will be funded in part with funds from grants and not from cash on hand. If Cell Cure Neurosciences were to lose its grant funding or BioTime is unable to continue to provide working capital to Cell Cure Neurosciences, or both, it may be required to delay, postpone, or cancel its clinical trials or limit the number of clinical trial sites, or otherwise reduce or curtail its operations unless it is able to obtain adequate financing from another source that could be used for its clinical trial. Also, OncoCyte will need to raise additional capital during 2016 to establish a CLIA certified laboratory to conduct the cancer diagnostic tests that it is developing.

Basic and diluted net loss per share

Basic and diluted net income (loss) per share – BioTime applies the two-class method for calculating basic earnings per share. Under the two-class method, net income, if any, will be reduced by preferred stock dividends and the residual amount is allocated between common stock and other participating securities based on their participation rights. Participating securities are comprised of Series A convertible preferred stock and participate in dividends, whether declared or not. Basic earnings per share is calculated by dividing net income or loss attributable to BioTime common shareholders by the weighted average number of common shares outstanding, net of unvested restricted stock subject to repurchase by BioTime, if any, during the period. For periods in which BioTime reported a net loss, the participating securities are not contractually obligated to share in the losses of BioTime, and accordingly, no losses have been allocated to the participating securities. Diluted earnings per share is calculated by dividing the net income or loss attributable to BioTime common shareholders by the weighted average number of common shares outstanding, adjusted for the effects of potentially dilutive common shares issuable under outstanding stock options and warrants, using the treasury-stock method, and convertible preferred stock, if any, using the if-converted method.

The primary components of weighted average shares of potentially dilutive common shares used to compute diluted net income per common share for the three months ended June 30, 2016 were approximately 2.4 million shares of treasury stock (see Note 10), and approximately 164,000 restricted stock units and outstanding stock options; for the six months ended June 30, 2016 potentially dilutive shares were approximately 3.4 million shares of treasury stock and approximately 94,000 restricted stock units and outstanding stock options (see Note 11)

The following common share equivalents were excluded from the computation of diluted net income (loss) per common share for the periods presented because including them would have been antidilutive (in thousands):

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements –There have been no recent accounting pronouncements since the recently issued pronouncements included in BioTime’s Form 10-Q for the three months ended March 31, 2016.

In August 2014, the FASB 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". ASU No. 2014-15 defines management's responsibility to assess an entity's ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. In connection with preparing financial statements for each annual and interim reporting period, ASU 2014-15 requires that an entity’s management evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable). ASU No. 2014-15 is effective for annual and interim reporting periods ending after December 15, 2016. Early adoption is permitted. BioTime has not elected early adoption and believes the impact of the adoption of ASU No. 2014-15 could have a material adverse impact on BioTime’s consolidated financial statements.

- Definition

Disclosure of accounting policy for the equity method of accounting for investments in common stock or other interests including unconsolidated subsidiaries, corporate joint ventures, noncontrolling interests in real estate ventures, limited partnerships, and limited liability companies. The accounting policy may include information such as: (1) initially recording an investment in the stock of an investee at cost; (2) adjusting the carrying amount of the investment to recognize the investor's share of the earnings or losses of the investee after the date of acquisition; and (3) adjustments to reflect the investor's share of changes in the investee's capital (dividends). This disclosure may also include a detailed description of the policy for determining the amount of equity method losses recognized after an investment has been reduced to zero as a result of previous losses, reasons for not using the equity method when the investor company owns 20 percent or more of the voting stock of the investee's company (including identification of the significant investee), reasons for using the equity method when the ownership percentage is less than 20 percent, and discussion of recognition of equity method losses when an investor's total investment in an investee includes, in addition to an investment in common stock, other investments such as preferred stock and loans to the investee. An entity also may describe how such investments are assessed for impairment.
