Recent Transactions Affecting Our Corporate Organization

Asterias Merger

On March 8, 2019, we acquired the outstanding shares of common stock of Asterias Biotherapeutics, Inc. (“Asterias”) held by stockholders other than BioTime via merger. In the acquisition, the outstanding shares of Asterias common stock held by stockholders other than BioTime were converted into shares of our common stock at an exchange ratio of 0.71 BioTime shares for each Asterias share.

Prior to May 13, 2016, Asterias was a majority-owned and consolidated subsidiary of BioTime. On May 13, 2016, BioTime’s percentage ownership decreased from 57.1% to 48.7% as a result of the sale of shares of common stock by Asterias in a public offering, resulting in BioTime’s loss of control of Asterias under generally accepted accounting principles in the U.S. (“GAAP”). Accordingly, BioTime deconsolidated Asterias effective May 13, 2016. From May 13, 2016 until the consummation of the merger on March 8, 2019, BioTime accounted for its ownership in Asterias under the equity method of accounting, electing the fair value option, with the investment carried on the consolidated balance sheet at fair value and all subsequent changes in fair value included in BioTime’s consolidated statements of operations in other income and expenses, net. The deconsolidation of Asterias is sometimes referred to as the “Asterias Deconsolidation” in this Report.

AgeX Deconsolidation and Distribution

On August 30, 2018, we entered into a Stock Purchase Agreement with Juvenescence Limited (“Juvenescence”) and AgeX Therapeutics, Inc. (“AgeX”), under which we sold 14,400,000 of our shares of AgeX common stock to Juvenescence for $3.00 per share. The transaction resulted in over $43 million in non-dilutive financing for BioTime.

Upon completion of that transaction, our percentage ownership of AgeX’s outstanding shares of common stock decreased from 80.4% to 40.2%, and Juvenescence’s percentage ownership increased from 5.6% to 45.8%. As a result of the transaction, as of August 30, 2018, AgeX was no longer our subsidiary and effective that date, due to the decrease in our percentage ownership in AgeX to below 50%, we deconsolidated AgeX’s consolidated financial statements and consolidated results of operations from ours under GAAP. Prior to that date, AgeX was our majority-owned and consolidated subsidiary. Beginning on August 30, 2018 through November 28, 2018 (the date on which AgeX began trading as a public company as discussed below), we accounted for AgeX using the equity method of accounting, electing the fair value option, recording the retained interest in AgeX at fair value on August 30, 2018 with all subsequent changes in fair value included in our consolidated statements of operations in other income and expenses, net. The deconsolidation of AgeX is sometimes referred to as the “AgeX Deconsolidation” in this Report.

On November 28, 2018, AgeX began trading as a public company on the NYSE American (under the symbol “AGE”) and, on that date, we distributed 12.7 million shares of AgeX common stock we owned to our shareholders, on a pro rata basis, in the ratio of one share of AgeX common stock for every 10 shares of our common stock they owned. This distribution was accounted for at fair value as a taxable, dividend-in-kind transaction in the aggregate amount of $34.4 million. Immediately following the distribution, we owned 1.7 million shares of AgeX common stock, all of which we still own, and which represents approximately 4.6% of AgeX’s outstanding common stock as of June 30, 2019. We hold the shares of AgeX common stock that we own as marketable equity securities. The distribution of AgeX common stock is sometimes referred to as the “AgeX Distribution” in this Report.

As of, and for each reporting period after August 30, 2018, the fair value of our ownership interest in AgeX will be determined by multiplying the fair value of a share of AgeX common stock by the number of such shares we own.

AgeX’s consolidated assets and liabilities are not included in BioTime’s unaudited condensed consolidated balance sheet at June 30, 2019 and December 31, 2018, due to the deconsolidation of AgeX on August 30, 2018.

BioTime’s unaudited consolidated statements of operations for the three and six months ended June 30, 2019 do not include AgeX’s consolidated results. For the three and six months ended June 30, 2018, BioTime’s unaudited consolidated results include AgeX’s consolidated results.

BIOTIME, INC. AND SUBSIDIARIES

NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

(UNAUDITED)

1. Organization and Business Overview

BioTime is a clinical-stage biotechnology company developing novel cell therapies for unmet medical needs. Our current focus is on therapies for degenerative retinal diseases, neurological conditions associated with demyelination, and aiding the body in detecting and combating cancer. BioTime’s programs are based on its proprietary cell-based therapy platform and associated development and manufacturing capabilities. With this platform BioTime develops and manufactures specialized, terminally-differentiated human cells from its pluripotent and progenitor cell starting materials. These differentiated cells are developed either to replace or support cells that are dysfunctional or absent due to degenerative disease or traumatic injury, or administered as a means of helping the body mount an effective immune response to cancer.

BioTime has three cell therapy programs in clinical development:

● OpRegen^®, a retinal pigment epithelium cell replacement therapy currently in a Phase I/IIa multicenter clinical trial for the treatment of advanced dry-age-related macular degeneration (“dry-AMD”) with geographic atrophy. There currently are no therapies approved by the U.S. Food and Drug Administration (“FDA”) for dry-AMD, which accounts for approximately 85-90% of all AMD cases and is a leading cause of blindness in people over the age of 65.

● OPC1, an oligodendrocyte progenitor cell therapy currently in a Phase I/IIa multicenter clinical trial for acute spinal cord injuries. This clinical trial has been partially funded by the California Institute for Regenerative Medicine.

● VAC2, an allogeneic (non-patient-specific or “off-the-shelf”) cancer immunotherapy of antigen-presenting dendritic cells currently in a Phase I clinical trial in non-small cell lung cancer. This clinical trial is being funded and conducted by Cancer Research UK, the world’s largest independent cancer research charity.

BioTime also has cell/drug delivery programs that are based upon its proprietary HyStem^® cell and drug delivery matrix technology. HyStem was designed to support the formulation, transfer, retention, and engraftment of cellular therapies.

BioTime is also enabling early-stage programs in other new technologies through its own research programs.

Asterias Merger

On November 7, 2018, BioTime, Asterias and Patrick Merger Sub, Inc., a wholly owned subsidiary of BioTime (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) whereby BioTime agreed to acquire all of the outstanding common stock of Asterias in a stock-for-stock transaction (the “Asterias Merger”).

On March 7, 2019, the shareholders of each of BioTime and Asterias approved the Merger Agreement. Prior to the consummation of the Merger Agreement, BioTime owned approximately 38% of Asterias’ issued and outstanding common stock and accounted for Asterias as an equity method investment.

On March 8, 2019, the Asterias merger closed with Asterias surviving as a wholly owned subsidiary of BioTime. The former stockholders of Asterias (other than BioTime) received 0.71 shares of BioTime common stock for every share of Asterias common stock they owned. BioTime issued 24,695,898 shares of common stock, including 58,085 shares issued in respect of restricted stock units issued by Asterias that immediately vested in connection with the closing of the Asterias Merger. The aggregate dollar value of such shares, based on the closing price of BioTime common stock on March 8, 2019, was $32.4 million. BioTime also assumed warrants to purchase shares of Asterias common stock.

The Asterias Merger has been accounted for using the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, which requires, among other things, that the assets and liabilities assumed be recognized at their fair values as of the acquisition date.

See Note 3 for a full discussion of the Asterias Merger.

Investment in OncoCyte

BioTime has significant equity holdings in OncoCyte Corporation (“OncoCyte”), a publicly traded company, which BioTime founded and, in the past, was a majority-owned consolidated subsidiary. OncoCyte (NYSE American: OCX) is developing confirmatory diagnostic tests for lung cancer utilizing novel liquid biopsy technology. As of June 30, 2019, BioTime owned 14.7 million shares of OncoCyte common stock, or 28% of its outstanding shares (see Note 16).

2. Basis of Presentation, Liquidity and Summary of Significant Accounting Policies

The unaudited condensed consolidated interim financial statements presented herein, and discussed below, have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. In accordance with those rules and regulations certain information and footnote disclosures normally included in comprehensive consolidated financial statements have been condensed or omitted. The condensed consolidated balance sheet as of December 31, 2018 was derived from the audited consolidated financial statements at that date, but does not include all the information and footnotes required by GAAP. These condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in BioTime’s Annual Report on Form 10-K for the year ended December 31, 2018.

The accompanying condensed consolidated interim financial statements, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of BioTime’s financial condition and results of operations. The condensed consolidated results of operations are not necessarily indicative of the results to be expected for any other interim period or for the entire year.

Principles of consolidation

BioTime’s condensed consolidated interim financial statements include the accounts of its subsidiaries. The following table reflects BioTime’s ownership, directly or through one or more subsidiaries, of the outstanding shares of its operating subsidiaries as of June 30, 2019.

Subsidiary	Field of Business	BioTime Ownership		Country
Asterias BioTherapeutics, Inc.	Cell therapy clinical development programs in spinal cord injury and oncology		100%	USA
Cell Cure Neurosciences Ltd. (“Cell Cure”)	Products to treat age-related macular degeneration		99% (1)	Israel
ES Cell International Pte. Ltd. (“ESI”)	Stem cell products for research, including clinical grade cell lines produced under cGMP		100%	Singapore
OrthoCyte Corporation (“OrthoCyte”)	Developing bone grafting products for orthopedic diseases and injuries		99.8%	USA

⁽¹⁾ Includes shares owned by BioTime and ESI.

For the three and six months ended June 30, 2018, BioTime’s unaudited consolidated results include AgeX’s consolidated results for the full period presented. As a result of the AgeX Deconsolidation, beginning on August 30, 2018 (a) AgeX’s consolidated financial statements and consolidated results are no longer a part of BioTime’s condensed consolidated interim financial statements and results, and (b) the fair value of AgeX common stock held by BioTime is now reflected on BioTime’s condensed consolidated balance sheet and the changes in the fair value of those shares during the applicable reporting period are reflected as gains or losses in BioTime’s condensed consolidated statements of operations included in other income and expenses, net.

All material intercompany accounts and transactions have been eliminated in consolidation. As of June 30, 2019, BioTime consolidated its direct and indirect wholly owned or majority-owned subsidiaries because BioTime has the ability to control their operating and financial decisions and policies through its ownership, and the noncontrolling interest is reflected as a separate element of shareholders’ equity on BioTime’s consolidated balance sheets.

Liquidity

Since inception, BioTime has incurred significant operating losses and has funded its operations primarily through the issuance of equity securities, sale of common stock of AgeX, a former subsidiary, receipt of research grants, royalties from product sales, license revenues and sales of research products. Additionally, BioTime raised $4.2 million in a sale of a portion of its OncoCyte holdings and $1.2 million in sales of a portion of its Hadasit Bio-Holdings Ltd. (“Hadasit”) holdings in July 2019 (see Note 16). At June 30, 2019, BioTime had an accumulated deficit of approximately $252.4 million, working capital of $12.6 million and shareholders’ equity of $131.8 million. BioTime has evaluated its projected cash flows and believes that its $16.7 million of cash, cash equivalents and marketable equity securities at June 30, 2019, plus the $4.2 million in net proceeds from the sale of OncoCyte shares of common stock in July 2019 and the value of its remaining equity investment in OncoCyte (which was approximately $21.7 million based on the closing price of OncoCyte common stock of $1.75 per share on August 6, 2019), provide sufficient cash, cash equivalents, and liquidity to carry out BioTime’s current planned operations through at least twelve months from the issuance date of the consolidated financial statements included herein. If BioTime needs near term working capital or liquidity to supplement its cash and cash equivalents for its operations, BioTime may sell some, or all, of its investments, as necessary.

The AgeX Distribution was completed on November 28, 2018 when AgeX became a publicly traded company (see Note 6). BioTime continues to hold a minority interest in AgeX that may be a source of additional liquidity to BioTime as a marketable equity security.

If the promissory note issued by Juvenescence in favor of BioTime discussed in Note 5 is converted into equity securities of Juvenescence prior to its maturity date, the Juvenescence equity securities may be marketable securities that BioTime may use to supplement its liquidity, as needed. If such promissory note is not converted, it is payable in cash, plus accrued interest, at maturity on August 30, 2020.

On March 8, 2019, with the consummation of the Asterias Merger, Asterias became BioTime’s wholly owned subsidiary. BioTime began consolidating Asterias’ operations and results with its operations and results beginning on March 8, 2019 (see Note 3). As BioTime integrates Asterias’ operations into its own, BioTime expects to make extensive reductions in headcount and to reduce non-clinical related spend, in each case, as compared to Asterias’ operations before the Asterias Merger.

BioTime’s projected cash flows are subject to various risks and uncertainties, and the unavailability or inadequacy of financing to meet future capital needs could force BioTime to modify, curtail, delay, or suspend some or all aspects of its planned operations. BioTime’s determination as to when it will seek new financing and the amount of financing that it will need will be based on BioTime’s evaluation of the progress it makes in its research and development programs, any changes to the scope and focus of those programs, any changes in grant funding for certain of those programs, and projection of future costs, revenues, and rates of expenditure. BioTime may be required to delay, postpone, or cancel clinical trials or limit the number of clinical trial sites, unless it is able to obtain adequate financing. In addition, BioTime has incurred and expects to continue incurring significant costs in connection with the acquisition of Asterias and with integrating its operations. BioTime may incur additional costs to maintain employee morale and to retain key employees. BioTime cannot assure that adequate financing will be available on favorable terms, if at all. Sales of additional equity securities by BioTime or its subsidiaries and affiliates could result in the dilution of the interests of current shareholders.

Business Combinations

BioTime accounts for business combinations, such as the Asterias Merger completed in March 2019, in accordance with ASC Topic 805, which requires the purchase price to be measured at fair value. When the purchase consideration consists entirely of shares of BioTime’s common stock, BioTime calculates the purchase price by determining the fair value, as of the acquisition date, of shares issued in connection with the closing of the acquisition. BioTime recognizes estimated fair values of the tangible assets and intangible assets acquired, including in-process research and development (“IPR&D”), and liabilities assumed as of the acquisition date, and records as goodwill any amount of the fair value of the tangible and intangible assets acquired and liabilities assumed in excess of the purchase price.

Equity method investments 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 a 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 in other income and expenses, net.

As further discussed in Note 4, BioTime has elected to account for its OncoCyte shares at fair value using the equity method of accounting because beginning on February 17, 2017, the respective date on which BioTime deconsolidated OncoCyte, BioTime has not had control of OncoCyte, as defined by GAAP, but continues to exercise significant influence over this company. Under the fair value method, BioTime’s value in shares of common stock it holds in OncoCyte is marked to market at each balance sheet date using the closing price of OncoCyte common stock on the NYSE American multiplied by the number of shares of OncoCyte held by BioTime, with changes in the fair value of the OncoCyte shares included in other income and expenses, net, in the consolidated statements of operations. The OncoCyte shares are considered level 1 assets as defined by ASC 820, Fair Value Measurements and Disclosures.

Prior to the Asterias Merger completed on March 8, 2019 discussed in Note 3, BioTime accounted for its Asterias shares held at fair value, using the equity method of accounting.

Revenue Recognition

During the first quarter of 2018, BioTime adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) ASU 2014-09, Revenues from Contracts with Customers (Topic 606), which created a single, principle-based revenue recognition model that supersedes and replaces nearly all existing U.S. GAAP revenue recognition guidance. BioTime adopted ASU 2014-09 using the modified retrospective transition method applied to those contracts which were not completed as of the adoption date. Results for reporting periods beginning on January 1, 2018 and thereafter are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with BioTime’s historical revenue recognition accounting under Topic 605.

BioTime recognizes revenue in a manner that depicts the transfer of control of a product or a service to a customer and reflects the amount of the consideration it is entitled to receive in exchange for such product or service. In doing so, BioTime follows a five-step approach: (i) identify the contract with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations, and (v) recognize revenue when (or as) the customer obtains control of the product or service. BioTime considers the terms of a contract and all relevant facts and circumstances when applying the revenue recognition standard. BioTime applies the revenue recognition standard, including the use of any practical expedients, consistently to contracts with similar characteristics and in similar circumstances.

BioTime’s largest source of revenue is currently related to government grants. In applying the provisions of ASU 2014-09, BioTime has determined that government grants are out of the scope of ASU 2014-09 because the government entities do not meet the definition of a “customer”, as defined by ASU 2014-09, as there is not considered to be a transfer of control of good or services to the government entities funding the grant. BioTime has, and will continue to, account for grants received to perform research and development services in accordance with ASC 730-20, Research and Development Arrangements, which requires an assessment, at the inception of the grant, of whether the grant is a liability or a contract to perform research and development services for others. If BioTime or a subsidiary receiving the grant is obligated to repay the grant funds to the grantor regardless of the outcome of the research and development activities, then BioTime is required to estimate and recognize that liability. Alternatively, if BioTime or a subsidiary receiving the grant is not required to repay, or if it is required to repay the grant funds only if the research and development activities are successful, then the grant agreement is accounted for as a contract to perform research and development services for others, in which case, grant revenue is recognized when the related research and development expenses are incurred (see Note 15).

Deferred grant revenues represent grant funds received from the governmental funding agencies for which the allowable expenses have not yet been incurred as of the balance sheet date reported. As of June 30, 2019, deferred grant revenue was immaterial.

Basic and diluted net income (loss) per share attributable to common shareholders

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 or restricted stock units, subject to repurchase by BioTime, if any, during the period. 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, convertible preferred stock, if any, using the if-converted method, and treasury stock held by subsidiaries, if any.

For the three months ended June 30, 2019, and for the three and six months ended June 30, 2018, BioTime reported a net loss attributable to common shareholders, and therefore, all potentially dilutive common stock was considered antidilutive for those periods. For the six months ended June 30, 2019, BioTime reported net income attributable to common shareholders, and therefore, performed an analysis of common share equivalents to determine their impact on diluted net income, and determined that none of the common share equivalents were dilutive.

The following weighted average 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):

	Three Months Ended June 30, (unaudited)				Six Months Ended June 30, (unaudited)
	2019		2018		2019		2018
Stock options		15,374		8,990		15,103		8,990
Warrants (1)		-		8,795		-		8,795
BioTime Warrants (2) (Note 3)		1,296		-		917		-
Restricted stock units		271		535		275		535

(1)	The warrants expired on October 1, 2018.
(2)	Although the BioTime Warrants are classified as liabilities, these warrants are considered for dilutive earnings per share calculations in accordance with ASC 260, Earnings Per Share, and determined to be anti-dilutive for the period presented.

Lease accounting and impact of adoption of the new lease standard

On January 1, 2019, BioTime adopted ASU 2016-02, Leases (Topic 842, “ASC 842”) and its subsequent amendments affecting BioTime: (i) ASU 2018-10, Codification Improvements to Topic 842, Leases, and (ii) ASU 2018-11, Leases (Topic 842): Targeted improvements, using the modified retrospective method (see Note 15).

BioTime management determines if an arrangement is a lease at inception. Leases are classified as either financing or operating, with classification affecting the pattern of expense recognition in the consolidated statements of operations. When determining whether a lease is a finance lease or an operating lease, ASC 842 does not specifically define criteria to determine “major part of remaining economic life of the underlying asset” and “substantially all of the fair value of the underlying asset.” For lease classification determination, BioTime continues to use (i) greater to or equal to 75% to determine whether the lease term is a major part of the remaining economic life of the underlying asset and (ii) greater to or equal to 90% to determine whether the present value of the sum of lease payments is substantially the fair value of the underlying asset. Under the available practical expedients, BioTime accounts for the lease and non-lease components as a single lease component. BioTime recognizes right-of-use (“ROU”) assets and lease liabilities for leases with terms greater than twelve months in the condensed consolidated balance sheet.

ROU assets represent BioTime’s right to use an underlying asset during the lease term and lease liabilities represent BioTime’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of BioTime’s leases do not provide an implicit rate, BioTime uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. BioTime uses the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. BioTime’s lease terms may include options to extend or terminate the lease when it is reasonably certain that BioTime will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Operating leases are included as right-of-use assets in property and equipment (see Note 15), and ROU lease liabilities, current and long-term, in the condensed consolidated balance sheets. Financing leases are included in property and equipment, and in financing lease liabilities, current and long-term, in BioTime’s condensed consolidated balance sheets.

In connection with the adoption on ASC 842 on January 1, 2019, BioTime derecognized net book value of leasehold improvements and corresponding lease liabilities of $1.9 million and $2.0 million, respectively, which was the carrying value of certain operating leases as of December 31, 2018, included in property and equipment and lease liabilities, respectively, recorded pursuant to build to suit lease accounting under the previous ASC 840 lease standard. The derecognition of these amounts from the superseded ASC 840 lease standard was offset by a cumulative effect adjustment of $0.1 million as a reduction of BioTime’s accumulated deficit on January 1, 2019. These build to suit leases were primarily related to the Alameda and the Cell Cure Leases described in Note 15. ASC 842 requires build to suit leases recognized on BioTime’s consolidated balance sheets as of December 31, 2018 to be derecognized upon the adoption of the new lease standard and be recognized in accordance with the new standard on January 1, 2019.

The adoption of ASC 842 had a material impact in BioTime’s consolidated balance sheets, with the most significant impact resulting from the recognition of ROU assets and lease liabilities for operating leases with remaining terms greater than twelve months on the adoption date (see Note 15). BioTime’s accounting for financing leases (previously referred to as “capital leases”) remained substantially unchanged.

Other recently adopted accounting pronouncements

Adoption of ASU 2016-18, Statement of Cash Flows (Topic 230) - On January 1, 2018, BioTime adopted ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents and restricted cash, and that restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the condensed consolidated statements of cash flows. The adoption of ASU 2016-18 did not have a material effect on BioTime’s condensed consolidated financial statements. However, prior period restricted cash balances included in prepaid expenses and other current assets, and in deposits and other long-term assets, on the condensed consolidated balance sheets was added to the beginning-of-period and end-of-period total consolidated cash and cash equivalents in the condensed consolidated statements of cash flows to conform to the current presentation shown below.

12

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the condensed consolidated balance sheet dates that comprise the total of the same such amounts shown in the condensed consolidated statements of cash flows for all periods presented herein and effected by the adoption of ASU 2016-18 (in thousands):

	June 30, 2019		December 31, 2018		June 30, 2018		December 31, 2017
		(unaudited)				(unaudited)
Cash and cash equivalents	$	8,210	$	23,587	$	27,207	$	36,838
Restricted cash included in prepaid expenses and other current assets (see Note 15)		-		346		346		-
Restricted cash included in deposits and other long-term assets (see Note 15)		586		466		78		847
Total cash, cash equivalents, and restricted cash as shown in the condensed consolidated statements of cash flows	$	8,796	$	24,399	$	27,631	$	37,685

Adoption of ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting - In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for non-employee share-based payment transactions. The new standard expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. ASU 2018-07 is effective for fiscal years beginning after December 15, 2018 (including interim periods within that fiscal year). BioTime adopted ASU 2018-07 on January 1, 2019. As BioTime does not have a significant number of nonemployee share-based awards, the application of the new standard did not have a material impact on its consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Adopted - The recently issued accounting pronouncements applicable to BioTime that are not yet effective should be read in conjunction with the recently issued accounting pronouncements, as applicable and disclosed in BioTime’s Annual Report on Form 10-K for the year ended December 31, 2018.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which modifies certain disclosure requirements for reporting fair value measurements. ASU 2018-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. BioTime will adopt this standard on January 1, 2020 and is currently evaluating the disclosure requirements and its effect on the consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This standard will be effective for interim and annual reporting periods beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for annual periods beginning after December 15, 2018. BioTime has not yet completed its assessment of the impact of the new standard on its consolidated financial statements.

3. Asterias Merger

On March 8, 2019, the Asterias Merger closed with Asterias surviving as a wholly owned subsidiary of BioTime. The former stockholders of Asterias (other than BioTime) received 0.71 shares of BioTime common stock (the “Merger Consideration”) for every share of Asterias common stock they owned (the “Merger Exchange Ratio”). BioTime issued 24,695,898 shares of common stock, including 58,085 shares issued in respect of restricted stock units issued by Asterias that immediately vested in connection with the closing of the Asterias Merger. The fair value of such shares, based on the closing price of BioTime common stock on March 8, 2019, was $32.4 million.

In connection with the closing of the Asterias Merger, BioTime assumed outstanding warrants to purchase shares of Asterias common stock, as further discussed below and in Note 11, and assumed sponsorship of the Asterias 2013 Equity Incentive Plan (see Note 12). All stock options to purchase shares of Asterias common stock outstanding immediately prior to the closing of the Asterias Merger were canceled at the closing for no consideration.

As of June 30, 2019, the assets and liabilities of Asterias have been included in the condensed consolidated balance sheet of BioTime. The results of operations of Asterias from March 8, 2019 through June 30, 2019 have been included in the condensed consolidated statement of operations of BioTime for the six months ended June 30, 2019.

Calculation of the purchase price

The calculation of the purchase price for the Asterias Merger and the Merger Consideration transferred on March 8, 2019 was as follows (in thousands, except for share and per share amounts):

	BioTime (38% ownership interest)			Shareholders other than BioTime (approximate 62% ownership interest)			Total
Outstanding Asterias common stock as of March 8, 2019		21,747,569			34,783,333	(1)		56,530,902	(1)
Exchange ratio		0.710			0.710			0.710
BioTime common stock issuable		15,440,774	(2)		24,695,898	(3)		40,136,672
Per share price of BioTime common stock as of March 8, 2019	$	1.31		$	1.31		$	1.31
Purchase price (in $000s)	$	20,227	(2)	$	32,353		$	52,580

(1)	Includes 81,810 shares of Asterias restricted stock unit awards that immediately vested on March 8, 2019 and converted into the right to receive shares of BioTime common stock based on the Merger Exchange Ratio, resulting in 58,085 shares of BioTime common stock issued on March 8, 2019 as part of the Merger Consideration. These restricted stock units were principally attributable to pre-combination services and included as part of the purchase price in accordance with ASC 805. See Note 12 for Asterias restricted stock units that vested on the closing of the Asterias Merger attributable to post-combination services that were recorded outside of the purchase price as an immediate charge to stock-based compensation expense.
(2)	Estimated fair value for BioTime’s previously held 38% ownership interest in Asterias common stock is part of the total purchase price of Asterias for purposes of the purchase price allocation under ASC 805 and for BioTime’s adjustment of its 38% interest to fair value at the effective date of the Asterias Merger and immediately preceding the consolidation of Asterias’ results with BioTime. No actual shares of BioTime common stock were issued to BioTime in connection with the Asterias Merger.
(3)	Net of a de minimis number of fractional shares which were paid in cash.

Estimated purchase price allocation

BioTime allocated the acquisition consideration to tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The fair value of the acquired tangible and identifiable intangible assets were determined based on inputs that are unobservable and significant to the overall fair value measurement. It is also based on estimates and assumptions made by management at the time of the acquisition. As such, this was classified as Level 3 fair value hierarchy measurements and disclosures.

The Merger Consideration allocation below is preliminary and as additional information becomes available, BioTime may further revise the preliminary acquisition consideration allocation. BioTime expects to finalize the acquisition consideration allocation by the end of 2019. Any such revisions or changes may be material.

14

The following table sets forth a preliminary allocation of the purchase price to Asterias’ tangible and identifiable intangible assets acquired and liabilities assumed on the closing of the Asterias Merger, with the excess recorded as goodwill (in thousands):

Assets acquired:
Cash and cash equivalents	$	3,117
Prepaid expenses and other assets, current and noncurrent		660
Machinery and equipment		369
Long-lived intangible assets - royalty contracts		650
Acquired in-process research and development (“IPR&D”)		46,540
Total assets acquired		51,336

Liabilities assumed:
Accrued liabilities and accounts payable		1,136
Liability classified warrants		867
Deferred license revenue		200
Long-term deferred income tax liability		12,965
Total liabilities assumed		15,168
Net assets acquired, excluding goodwill (a)		36,168
Fair value of BioTime common stock held by Asterias (b)		3,435
Total purchase price (c)		52,580
Estimated goodwill (c-a-b)	$	12,977

The valuation of identifiable intangible assets and their estimated useful lives are as follows (in thousands, except for useful life):

	Preliminary Estimated Asset Fair Value		Useful Life (Years)
	(in thousands, except for useful life)
In process research and development (“IPR&D”)	$	46,540		n/a
Royalty contracts		650		5
	$	47,190

The following is a discussion of the valuation methods used to determine the fair value of Asterias’ significant assets and liabilities in connection with the Asterias Merger:

Acquired In-Process Research and Development (“IPR&D”) and Deferred Income Tax Liability - The fair value of identifiable acquired in-process research and development intangible assets consisting of $31.7 million pertaining to the AST-OPC1 program that is currently in a Phase 1/2a clinical trial for spinal cord injuries (“SCI”), which has been partially funded by the California Institute for Regenerative Medicine and $14.8 million pertaining to the AST-VAC2 program, which is a non-patient-specific (“off-the-shelf”) cancer immunotherapy derived from pluripotent stem cells for which a clinical trial in non-small cell lung cancer is being funded and sponsored by Cancer Research UK. The identification of these intangible assets are based on consideration of historical experience and a market participant’s view further discussed below; collectively, the AST-OPC1 and the AST-VAC2 are referred to as the “AST-Clinical Programs”. These intangible assets are valued primarily through the use of a probability weighted discounted cash flow method under the income approach further discussed below. BioTime considered the AST-VAC1 program, an autologous product candidate, manufactured from cells that come from the patient, and due to significant risks, substantial costs and limited opportunities in its current state associated with the AST-VAC1 program, BioTime management considered this program to have de minimis value.

BioTime determined that the estimated aggregate fair value of the AST-Clinical programs was $46.5 million as of the acquisition date using a probability weighted discounted cash flow method for each respective program. This approach estimates the probability of the AST-Clinical Programs achieving successful completion of remaining clinical trials and related approvals into the valuation technique.

15

To calculate fair value of the AST-Clinical programs under the discounted cash flow method, BioTime used probability-weighted, projected cash flows discounted at a rate considered appropriate given the significant inherent risks associated with cell therapy development by clinical-stage companies. Cash flows were calculated based on estimated projections of revenues and expenses related to each respective program. Cash flows were assumed to extend through a seven-year market exclusivity period for the AST-OPC1 program from the date of market launch. Revenues from commercialization of the AST-Clinical Programs were based on estimated market potential for the indication of each program. The resultant cash flows were then discounted to present value using a weighted-average cost of capital for companies with profiles substantially similar to that of BioTime, which BioTime believes represents the rate that market participants would use to value the assets. BioTime compensated for the phase of development of the program by applying a probability factor to its estimation of the expected future cash flows. The projected cash flows were based on significant assumptions, including the indications in which BioTime will pursue development of the AST-Clinical programs, the time and resources needed to complete the development and regulatory approval, estimates of revenue and operating profit related to the program considering its stage of development, the life of the potential commercialized product, market penetration and competition, and risks associated with achieving commercialization, including delay or failure to obtain regulatory approvals to conduct clinical studies, failure of clinical studies, delay or failure to obtain required market clearances, and intellectual property litigation.

These IPR&D assets are indefinite-lived intangible assets until the completion or abandonment of the associated research and development (“R&D”) efforts. Once the R&D efforts are completed or abandoned, the IPR&D will either be amortized over the asset life as a finite-lived intangible asset or be impaired, respectively, in accordance with ASC 350, Intangibles - Goodwill and Other. In accordance with ASC 350, goodwill and acquired IPR&D are determined to have indefinite lives and, therefore, are not amortized. Instead, they are tested for impairment at least annually and between annual tests if BioTime becomes aware of an event or a change in circumstances that would indicate the asset may be impaired.

Because the IPR&D (prior to completion or abandonment of the R&D) is considered an indefinite-lived asset for accounting purposes, the fair value of the IPR&D on the acquisition date creates a deferred income tax liability (“DTL”) in accordance with ASC 740, Income Taxes (see Note 13). This DTL is computed using the fair value of the IPR&D assets on the acquisition date multiplied by BioTime’s federal and state income tax rates. While this DTL would reverse on impairment or sale or commencement of amortization of the related intangible assets, those events are not anticipated under ASC 740 for purposes of predicting reversal of a temporary difference to support the realization of deferred tax assets, except for certain deferred tax assets and credit carryforwards that are also indefinite in nature as of the closing of the Asterias Merger, which may be considered for reversal under ASC 740 as further discussed in Note 13.

Royalty contracts - Asterias has certain royalty revenues for “research only use” culture media for pre-clinical research applications under certain, specific patent families under contracts which preclude the customers to sell for commercial use or for clinical trials. These royalty cash flows are generated under certain specific patent families which Asterias previously acquired from Geron Corporation (“Geron”). Asterias pays Geron a royalty for all royalty revenues received from these contracts. Because these patents are a subset of the clinical programs discussed above, are expected to continue to generate revenues for Asterias and are not to be used in the AST-OPC1 or the AST-VAC2 programs, these patents are considered to be separate long-lived intangible assets under ASC 805. These intangible assets are also valued primarily through the use of the discounted cash flow method under the income approach, and will be amortized over their useful life, estimated to be 5 years. The discounted cash flow method estimated the amount of net royalty income that can be expected under the contracts in future years. The amounts were based on observed historical trends in the growth of these revenue streams, and were estimated to terminate in approximately five years, when the key patents under these contracts will begin to expire. The resulting cash flows were discounted to the valuation date based on a rate of return that recognizes a lower level of risk associated with these assets as compared to the AST-Clinical programs discussed above.

Deferred license revenue - In September 2018, Asterias and Novo Nordisk A/S (“Novo Nordisk”) entered into an option for Novo Nordisk or its designated U.S. affiliate to license, on a non-exclusive basis, certain intellectual property related to culturing pluripotent stem cells, such as hES cells, in suspension. Under the terms of the option, Asterias received a one-time upfront payment of $1.0 million, in exchange for a 24-month period option to negotiate a non-exclusive license during which time Asterias has agreed to not grant any exclusive licenses inconsistent with the Novo Nordisk option. This option is considered a performance obligation as it provides Novo Nordisk with a material right that it would not receive without entering into the contract.

For business combination purposes under ASC 805, the fair value of this performance obligation to BioTime, from a market participant perspective, is the estimated costs BioTime may incur, plus a normal profit margin for the level of effort required to perform under the contract after the acquisition date, assuming Novo Nordisk exercised its option, including, but not limited to, negotiation costs, legal fees, arbitration, if any, and other related costs. Management has estimated those costs, plus a normal profit margin, to be approximately $200,000 in the estimated purchase price allocation.

Liability classified warrants - On May 13, 2016, in connection with a common stock offering, Asterias issued warrants to purchase 2,959,559 shares of Asterias common stock (the “Asterias Warrants”) with an exercise price of $4.37 per share that expire in five years from the issuance date, or May 13, 2021. As of the closing of the Asterias Merger, there were 2,813,159 Asterias Warrants outstanding. The Asterias Warrants contain certain provisions in the event of a Fundamental Transaction, as defined in the warrant agreement governing the Asterias Warrants (“Warrant Agreement”), that Asterias or any successor entity will be required to purchase, at a holder’s option, exercisable at any time concurrently with or within thirty days after the consummation of the fundamental transaction, the Asterias Warrants for cash in an amount equal to the calculated value of the unexercised portion of such holder’s warrants, determined in accordance with the Black-Scholes option pricing model with significant inputs as specified in the Warrant Agreement. The Asterias Merger was a Fundamental Transaction for purposes of the Asterias Warrants.

16

The fair value of the Asterias Warrants was determined by using Black-Scholes option pricing models which take into consideration the probability of the fundamental transaction, which for purposes of the above valuation was assumed to be at 100% and net cash settlement occurring, using the contractual remaining term of the warrants. In applying these models, these inputs included key assumptions including the per share closing price of BioTime common stock on March 8, 2019, volatility computed in accordance with the provisions of the Warrant Agreement and, to a large extent, assumptions based on discussions with a majority of the holders of the Asterias Warrants since the closing of the Asterias Merger to settle the Asterias Warrants in cash or in shares of BioTime common stock. Based on such discussions, BioTime believes the fair value of the Asterias Warrants as of the closing of the Asterias Merger is not subject to change significantly, however, to the extent any Asterias Warrants that were not settled in cash or in BioTime common stock discussed below, were automatically converted to BioTime warrants 30 days after the closing of the Asterias Merger. In April 2019, Asterias Warrants representing approximately $372,000 in fair value were settled: $332,000 in fair value was settled in exchange for 251,835 shares of BioTime common stock, and $40,000 in fair value was settled in exchange for cash. The Asterias Warrants settled in exchange for shares of BioTime common stock were held by Broadwood Partners, L.P., an Asterias and BioTime shareholder. The Asterias Warrants settled in exchange for cash were held by other parties. The remaining Asterias Warrants (representing approximately $495,000 in fair value as of March 31, 2019) were converted into warrants to purchase shares of BioTime common stock using the Merger Exchange Ratio (the “BioTime Warrants”).

As of June 30, 2019, the total number of shares of BioTime common stock subject to warrants that were assumed by BioTime in connection with the Asterias Merger was 1,089,900, with similar terms and conditions retained under the BioTime Warrants as per the original Warrant Agreements. The BioTime Warrants have an exercise price of $6.15 per warrant share and expire on May 13, 2021. BioTime is accounting for the outstanding BioTime Warrants as a liability at fair value, with subsequent changes to the fair value of the BioTime Warrants at each reporting period thereafter included in the consolidated statement of operations (see Note 11).

Fair value of BioTime common stock held by Asterias - As of March 8, 2019, Asterias held 2,621,811 shares of BioTime common stock as marketable securities on its standalone financial statements. The fair value of those shares acquired by BioTime from Asterias is determined based on the $1.31 per share closing price of BioTime common stock on March 8, 2019. Although treasury shares are not considered an asset and were retired upon BioTime’s acquisition of Asterias, the fair value of those shares is a part of the purchase price allocation shown in the tables above. These BioTime shares were retired at the completion of the Asterias Merger.

Goodwill - Goodwill is calculated as the difference between the acquisition date fair value of the consideration transferred and the values assigned to the assets acquired and liabilities assumed. Goodwill is not amortized but is tested for impairment at least annually, or more frequently if circumstances indicate potential impairment.

Depending on the structure of a particular acquisition, goodwill and identifiable intangible assets may not be deductible for tax purposes. Goodwill recorded in the Asterias Merger is not expected to be deductible for tax purposes (see Note 13).

During the three and six months ended June 30, 2019, BioTime incurred $0.9 million and $4.4 million, respectively, in acquisition related costs which were recorded in general and administrative expenses in the accompanying condensed consolidated statements of operations.

Prior to the Asterias Merger being consummated in March 2019, BioTime elected to account for its 21.7 million shares of Asterias common stock at fair value using the equity method of accounting. The fair value of the Asterias shares was approximately $20.2 million as of March 8, 2019, the closing date of the Asterias Merger, based on $0.93 per share, which was calculated by multiplying (a) $1.31, the closing price of BioTime common stock on such date by (b) the Merger Exchange Ratio. The fair value of the Asterias shares was approximately $13.5 million as of December 31, 2018, based on the closing price of Asterias common stock of $0.62 per share on such date. Accordingly, BioTime recorded an unrealized gain of $6.7 million for the six months ended June 30, 2019, representing the change in fair value of Asterias common stock from December 31, 2018 to March 8, 2019. For the six months ended June 30, 2018, BioTime recorded an unrealized loss of $19.6 million on the Asterias shares due to the decrease in Asterias’ stock price from December 31, 2017 to June 30, 2018 from $2.25 per share to $1.35 per share. All share prices were determined based on the closing price of BioTime or Asterias common stock on the NYSE American on the applicable dates.

4. Equity Method Accounting for Common Stock of OncoCyte, at Fair Value

BioTime elected to account for its 14.7 million shares of OncoCyte common stock at fair value using the equity method of accounting beginning on February 17, 2017, the date of the OncoCyte Deconsolidation. The OncoCyte shares had a fair value of $36.5 million as of June 30, 2019 and a fair value of $20.3 million as of December 31, 2018, based on the closing price of OncoCyte of $2.49 per share and $1.38 per share on those respective dates.

17

For the three months ended June 30, 2019, BioTime recorded an unrealized loss of $21.4 million due to the decrease in OncoCyte’s stock price from $3.95 per share at March 31, 2019 to $2.49 per share at June 30, 2019. For the three months ended June 30, 2018, BioTime recorded an unrealized gain of $6.6 million due to the increase in OncoCyte’s stock price from $2.10 per share at March 31, 2018 to $2.55 per share at June 30, 2018.

For the six months ended June 30, 2019, BioTime recorded an unrealized gain of $16.3 million due to the increase in OncoCyte’s stock price from $1.38 per share at December 31, 2018 to $2.49 per share at June 30, 2019. For the six months ended June 30, 2018, BioTime recorded an unrealized loss of $30.8 million due to the decrease in OncoCyte’s stock price from $4.65 per share at December 31, 2017 to $2.55 per share at June 30, 2018.

All share prices are determined based on the closing price of OncoCyte common stock on the NYSE American on the applicable dates, or the last day of trading of the applicable quarter, if the last day of a quarter fell on a weekend.

5. Sale of Significant Ownership Interest in AgeX to Juvenescence Limited

On August 30, 2018, BioTime entered into a Stock Purchase Agreement with Juvenescence Limited and AgeX, pursuant to which BioTime sold 14.4 million shares of common stock of AgeX to Juvenescence for $3.00 per share, or an aggregate purchase price of $43.2 million (the “Purchase Price”). Juvenescence paid $10.8 million of the Purchase Price at closing, issued an unsecured convertible promissory note dated August 30, 2018 in favor of BioTime for $21.6 million (the “Promissory Note”), and paid $10.8 million on November 2, 2018. The Stock Purchase Agreement contains customary representations, warranties and indemnities from BioTime relating to the business of AgeX, including an indemnity cap of $4.3 million, which is subject to certain exceptions. The transactions contemplated by the Stock Purchase Agreement are referred to as the Juvenescence Transaction in this Report.

The Promissory Note bears interest at 7% per annum, with principal and accrued interest payable at maturity on August 30, 2020. The Promissory Note cannot be prepaid prior to maturity or conversion. On the maturity date, if a “Qualified Financing” (as defined below) has not occurred, BioTime will have the right, but not the obligation, to convert the principal balance of the Promissory Note and accrued interest then due into Series A preferred shares of Juvenescence at a conversion price of $15.60. Upon the occurrence of a Qualified Financing on or before the maturity date, the principal balance of the Promissory Note and accrued interest will automatically convert into a number of shares of the class of equity securities of Juvenescence sold in the Qualified Financing, at the price per share at which the Juvenescence securities are sold in the Qualified Financing; and, if AgeX common stock is listed on a national securities exchange in the U.S., the number of shares of the class of equity securities issuable upon conversion may be increased depending on the market price of AgeX common stock. A Qualified Financing is generally defined as an underwritten initial public offering of Juvenescence equity securities in which gross proceeds are not less than $50.0 million. The Promissory Note is not transferable, except in connection with a change of control of BioTime.

For the three and six months ended June 30, 2019, BioTime recognized $378,000 and $756,000, respectively, in interest income on the Promissory Note. As of June 30, 2019, the principal and accrued interest balance of the Promissory Note was $22.9 million.

Shareholder Agreement

BioTime and Juvenescence entered into a Shareholder Agreement, dated August 30, 2018, setting forth the governance, approval and voting rights of the parties with respect to their holdings of AgeX common stock, including rights of representation on the AgeX Board of Directors, approval rights, preemptive rights, rights of first refusal and co-sale and drag-along and tag-along rights for so long as either BioTime or Juvenescence continue to own at least 15% of the outstanding shares of AgeX common stock. Under the Shareholder Agreement, Juvenescence and BioTime each had the right to designate two persons to a six-member AgeX Board of Directors, with the remaining two individuals to be independent of Juvenescence and BioTime. Following Juvenescence’s payment of $10.8 million on November 2, 2018 under the Stock Purchase Agreement, Juvenescence had the right to designate an additional member of the AgeX Board of Directors. As of July 30, 2019, Juvenescence has not exercised such right. Immediately following the AgeX Distribution on November 28, 2018 (see Note 6), BioTime owned 1.7 million shares of AgeX common stock, representing 4.8% of AgeX’s then issued and outstanding shares of common stock. Accordingly, in accordance with the Shareholder Agreement, as of November 28, 2018, BioTime had no right to designate any member to the AgeX Board of Directors.

18

In connection with the Juvenescence Transaction, the termination provision of the Shared Facilities Agreement (see Note 10) entitling AgeX or BioTime to terminate the agreement upon six months advance written notice was amended. Pursuant to the amendment, following the deconsolidation of AgeX from BioTime’s consolidated financial statements on August 30, 2018 (see Notes 6 and 10), each party retains the right to terminate the Shared Facilities Agreement at any time by giving the other party six months advance written notice, but BioTime may not do so prior to September 1, 2020.

On May 7, 2019, AgeX provided written notice that it will terminate its use of BioTime’s office and laboratory facilities as of July 31, 2019. On July 3, 2019, AgeX provided written notice that the remaining shared services would terminate as of September 30, 2019.

6. Deconsolidation and Distribution of AgeX

Deconsolidation of AgeX

On August 30, 2018, BioTime sold 14.4 million shares of the common stock of AgeX to Juvenescence (see Note 5). Immediately before that sale, BioTime and Juvenescence owned 80.4% and 5.6%, respectively, of AgeX’s outstanding common stock. Immediately following that sale, BioTime and Juvenescence owned 40.2% and 45.8%, respectively, of AgeX’s outstanding common stock. As a result, on August 30, 2018, AgeX was no longer a subsidiary of BioTime and, as of that date, BioTime experienced a “loss of control” of AgeX, as defined by GAAP. Loss of control is deemed to have occurred when, among other things, a parent company owns less than a majority of the outstanding common stock of a subsidiary, lacks a controlling financial interest in the subsidiary, and is unable to unilaterally control the subsidiary through other means such as having, or being able to obtain, the power to elect a majority of the subsidiary’s Board of Directors based solely on contractual rights or ownership of shares representing a majority of the voting power of the subsidiary’s voting securities. All of these loss-of-control factors were present with respect to BioTime’s ownership interest in AgeX as of August 30, 2018. Accordingly, BioTime deconsolidated AgeX’s consolidated financial statements and consolidated results from BioTime’s unaudited condensed consolidated financial statements and consolidated results effective on August 30, 2018, in accordance with ASC, 810-10-40-4(c).

In connection with the Juvenescence Transaction discussed in Note 5 and the AgeX Deconsolidation on August 30, 2018, in accordance with ASC 810-10-40-5, BioTime recorded a gain on deconsolidation of $78.5 million, which includes a financial reporting gain on the sale of the AgeX shares of $39.2 million, during the year ended December 31, 2018, included in other income and expenses, net, in the consolidated statements of operations.

Distribution of AgeX Shares

On November 28, 2018, BioTime distributed 12.7 million shares of AgeX common stock owned by BioTime to holders of BioTime common stock, on a pro rata basis, in the ratio of one share of AgeX common stock for every 10 shares of BioTime common stock owned. The AgeX Distribution was accounted for at fair value as a dividend-in-kind in the aggregate amount of $34.4 million, which was determined by multiplying (a) the 12.7 million shares distributed to BioTime shareholders by (b) $2.71, the closing price of AgeX common stock on the NYSE American on November 29, 2018, the first trading day of AgeX common stock.

Because BioTime has an accumulated deficit in its consolidated shareholders’ equity, the entire fair value of the AgeX Distribution was charged against common stock equity included in the consolidated statements of changes in shareholders’ equity for the year ended December 31, 2018.

Immediately following the AgeX Distribution, BioTime owned 1.7 million shares of AgeX common stock, all of which it still owns, and which represents approximately 4.6% of AgeX’s outstanding common stock as of June 30, 2019 and which shares BioTime holds as marketable equity securities.

(3)	Includes $0.3 million of transaction costs related to the Asterias Merger (see Note 3) recorded outside of the business combination.

In connection with the Asterias Merger, several Asterias employees were terminated as of the Asterias Merger date. Three of these employees had employment agreements with Asterias which entitled them to change in control and separation payments in the aggregate of $2.0 million, which such conditions were met on the Asterias Merger date. Accordingly, $2.0 million was accrued and recorded in general and administrative expenses on the merger date and paid in April 2019.

Additionally, BioTime entered into a plan of termination with substantially all other previous employees of Asterias with potential separation payments in the aggregate of $0.5 million. Termination dates for these individuals ranged from May 31, 2019 to June 28, 2019. These employees were required to provide services related to the transition and be an employee of the combined company as of their date of termination in order to receive separation benefits. Since the employees were required to render future services after the merger date, BioTime recorded the aggregate liability ratably over their respective service periods from the Asterias Merger date through the above termination dates, in accordance with ASC 420, Exit or Disposal Cost Obligations. As of June 30, 2019, a total of $0.3 million was accrued for these separation payments which represents the portion of the payments earned through June 30, 2019. This amount was paid in July 2019.

In connection with the planned relocation of BioTime’s corporate headquarters to Carlsbad, California, discussed in Note 15, in June 2019, BioTime entered into a plan of termination with certain BioTime employees with potential separation payments in the aggregate of $0.5 million. Termination dates for these individuals range from August 9, 2019 to September 30, 2019. These employees must provide services related to the transition of services and activities in connection with the relocation and be an employee of BioTime as of their date of termination in order to receive separation benefits. BioTime will record the aggregate liability ratably over their respective service periods from June through the above termination dates, in accordance with ASC 420.

As of June 30, 2019, a total of $0.2 million was accrued for these BioTime employee separation payments which represents the portion of the payments earned through June 30, 2019.

10. Related Party Transactions

Shared Facilities and Service Agreements with Affiliates

The receivables from affiliates shown on the condensed consolidated balance sheet as of December 31, 2018, primarily represent amounts owed to BioTime by OncoCyte and AgeX under separate Shared Facilities and Service Agreements (each a “Shared Facilities Agreement”), with amounts owed by OncoCyte comprising most of that amount. These outstanding amounts were paid in full in the first quarter of 2019. Under the terms of the Shared Facilities Agreements, BioTime allows OncoCyte and AgeX to use BioTime’s premises and equipment located at BioTime’s headquarters in Alameda, California for the purpose of conducting business. BioTime also provides accounting, billing, bookkeeping, payroll, treasury, payment of accounts payable, and other similar administrative services to OncoCyte and AgeX. BioTime may also provide the services of attorneys, accountants, and other professionals who may provide professional services to BioTime and its other subsidiaries. BioTime also has provided OncoCyte and AgeX with the services of laboratory and research personnel, including BioTime employees and contractors, for the performance of research and development work for OncoCyte and AgeX at the premises.

21

BioTime charges OncoCyte and AgeX a “Use Fee” for services provided and for use of BioTime facilities, equipment, and supplies. For each billing period, BioTime prorates and allocates to OncoCyte and AgeX costs incurred, including costs for services of BioTime employees and use of equipment, insurance, leased space, professional services, software licenses, supplies and utilities. The allocation of costs depends on key cost drivers, including actual documented use, square footage of facilities used, time spent, costs incurred by BioTime for OncoCyte and AgeX, or upon proportionate usage by BioTime, OncoCyte and AgeX, as reasonably estimated by BioTime. BioTime, at its discretion, has the right to charge OncoCyte and AgeX a 5% markup on such allocated costs. The allocated cost of BioTime employees and contractors who provide services is based upon the number of hours or estimated percentage of efforts of such personnel devoted to the performance of services.

The Use Fee is determined and invoiced to OncoCyte and AgeX on a regular basis, generally monthly or quarterly. Each invoice is payable in full within 30 days after receipt. Any invoice, or portion thereof, not paid in full when due will bear interest at the rate of 15% per annum until paid, unless the failure to make a payment is due to any inaction or delay in making a payment by BioTime. Through June 30, 2019, BioTime has not charged OncoCyte or AgeX any interest.

In addition to the Use Fee, OncoCyte and AgeX reimburse BioTime for any out of pocket costs incurred by BioTime for the purchase of office supplies, laboratory supplies, and other goods and materials and services for the account or use of OncoCyte or AgeX. BioTime is not obligated to purchase or acquire any office supplies or other goods and materials or any services for OncoCyte or AgeX, and if any such supplies, goods, materials or services are obtained, BioTime may arrange for the suppliers to invoice OncoCyte or AgeX directly.

The Shared Facilities Agreements remain in effect until a party gives the other party written notice that the Shared Facilities Agreement will terminate on December 31 of that year, or unless it is otherwise terminated under another provision of the agreement. In addition, BioTime and AgeX may each terminate their Shared Facilities Agreement prior to December 31 of the year by giving the other party written six months’ notice to terminate, but BioTime may not do so prior to September 1, 2020.

On May 7, 2019, AgeX provided written notice that it will terminate its use of BioTime’s office and laboratory facilities as of July 31, 2019. On July 3, 2019, AgeX provided written notice that the remaining shared services would terminate as of September 30, 2019. On July 30, 2019, OncoCyte provided written notice that it planned to terminate shared services effective as of September 30, 2019, except for the use of shared facilities, which remains in force.

In the aggregate, BioTime charged Use Fees to OncoCyte and AgeX as follows (in thousands):

	Three Months Ended June 30, (unaudited)				Six Months Ended June 30, (unaudited)
	2019		2018		2019		2018
Research and development	$	491	$	217	$	984	$	437
General and administrative		179		175		411		346
Total use fees	$	670	$	392	$	1,395	$	783

The Use Fees charged to OncoCyte and AgeX shown above are not reflected in revenues, but instead BioTime’s general and administrative expenses and research and development expenses are shown net of those charges in the condensed consolidated statements of operations.

BioTime accounts for receivables from affiliates, net of payables to affiliates, if any, for similar shared services and other transactions BioTime’s consolidated subsidiaries may enter into with nonconsolidated affiliates. BioTime and the affiliates record those receivables and payables on a net basis since BioTime and the affiliates intend to exercise a right of offset of the receivable and the payable and to settle the balances net by having the party that owes the other party pay the net balance owed.

Transactions with Ascendance Biotechnology, Inc.

On March 21, 2018, AgeX and Ascendance Biotechnology, Inc. (“Ascendance”), an equity method investee of AgeX and former equity method investee of BioTime, entered into an Asset Purchase Agreement (the “Asset Agreement”) in which AgeX purchased for $800,000 in cash certain assets consisting primarily of in-process research and development assets related to stem cell derived cardiomyocytes (heart muscle cells) to be developed by AgeX. The transaction was considered an asset acquisition rather than a business combination in accordance with ASC 805. Accordingly, the $800,000 purchase price was expensed on the acquisition date as acquired in-process research and development as those assets have no alternative future use. Also, on March 21, 2018, BioTime received $0.2 million from Ascendance as settlement of its accounts receivable from Ascendance.

22

Disposition of ownership interest in Ascendance

On March 23, 2018, Ascendance was acquired by a third party in a merger through which AgeX received approximately $3.2 million in cash for its shares of Ascendance common stock. AgeX recognized a $3.2 million gain on the sale of its equity method investment in Ascendance, which is included in other income and expenses, net, for the six months ended June 30, 2018.

Other related party transactions

In February 2018, Alfred D. Kingsley, the Chairman of BioTime’s Board of Directors and a former officer and director of AgeX, purchased AgeX stock purchase warrants entitling him to purchase 248,600 shares of AgeX common stock at an exercise price of $2.50 per share. AgeX received $124,300, or $0.50 per warrant, from Mr. Kingsley. The warrants were sold to Mr. Kingsley on the same terms as other warrants were sold by AgeX to other unaffiliated investors.

BioTime currently pays $5,050 per month for the use of approximately 900 square feet of office space in New York City, which is made available to BioTime on a month-by-month basis by one of its directors at an amount that approximates his cost (see Note 15).

In April 2019, BioTime issued 251,835 shares of BioTime common stock to Broadwood Partners, L.P., an Asterias and BioTime shareholder, in exchange for the settlement of Asterias Warrants in connection with the Asterias Merger (see Note 3).

In connection with the putative shareholder class action lawsuit filed in February 2019 challenging the Asterias Merger (see Note 15), BioTime has agreed to pay for the legal defense of Neal Bradsher, director, and Broadwood Partners, L.P., a shareholder of BioTime, and Broadwood Capital, Inc., which manages Broadwood Partners, L.P., all of which were named in the lawsuit. Through June 30, 2019, BioTime has incurred a total of $140,000 in legal expenses on behalf of the director, shareholder, and the manager of the shareholder.

11. Shareholders’ Equity

Preferred Shares

BioTime is authorized to issue 2,000,000 preferred shares. The preferred shares may be issued in one or more series as the board of directors may determine by resolution. The board of directors is authorized to fix the number of shares of any series of preferred shares and to determine or alter the rights, preferences, privileges, and restrictions granted to or imposed on the preferred shares as a class, or upon any wholly unissued series of any preferred shares. The board of directors may, by resolution, increase or decrease (but not below the number of shares of such series then outstanding) the number of shares of any series of preferred shares subsequent to the issue of shares of that series. There are no preferred shares issued and outstanding.

Common Shares

At June 30, 2019, BioTime was authorized to issue 250,000,000 common shares, no par value. As of June 30, 2019, and December 31, 2018, BioTime had 149,642,861 and 127,135,774 issued and outstanding common shares, respectively.

In April 2017, BioTime entered into a Controlled Equity Offering^SM Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co., as sales agent (“Cantor Fitzgerald”), pursuant to which BioTime may offer and sell, from time to time, through Cantor Fitzgerald, shares of BioTime common stock having an aggregate offering price of up to $25,000,000. BioTime is not obligated to sell any shares under the Sales Agreement. Subject to the terms and conditions of the Sales Agreement, Cantor Fitzgerald will use commercially reasonable efforts, consistent with its normal trading and sales practices, applicable state and federal law, rules and regulations, and the rules of the NYSE American, to sell the shares from time to time based upon BioTime’s instructions, including any price, time or size limits specified by BioTime. Under the Sales Agreement, Cantor Fitzgerald may sell the shares by any method deemed to be an “at-the-market” offering as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended, or by any other method permitted by law, including in privately negotiated transactions. Cantor Fitzgerald’s obligations to sell the shares under the Sales Agreement are subject to satisfaction of certain conditions, including the continued effectiveness of BioTime’s Registration Statement on Form S-3, which became effective on May 5, 2017. As of June 30, 2019, $24.2 million remained available for sale through the Sales Agreement.

BioTime agreed to pay Cantor Fitzgerald a commission of 3.0% of the aggregate gross proceeds from each sale of shares, reimburse legal fees and disbursements and provide Cantor Fitzgerald with customary indemnification and contribution rights. The Sales Agreement may be terminated by Cantor Fitzgerald or BioTime at any time upon notice to the other party, or by Cantor Fitzgerald at any time in certain circumstances, including the occurrence of a material and adverse change in BioTime’s business or financial condition that makes it impractical or inadvisable to market the shares or to enforce contracts for the sale of the shares.

Warrants

BioTime (previously Asterias) Warrants - Liability Classified

In March 2019, in connection with the closing of the Asterias Merger, BioTime assumed outstanding Asterias Warrants. As of June 30, 2019, the total number of shares of BioTime common stock subject to warrants that were assumed by BioTime in connection with the Asterias Merger was 1,089,900 (representing approximately $289,000 in fair value as of June 30, 2019), which were converted to BioTime Warrants 30 days after the closing of the Asterias Merger, with similar terms and conditions retained under the BioTime Warrants as per the original Warrant Agreements. The BioTime Warrants have an exercise price of $6.15 per warrant share and expire on May 13, 2021. BioTime is accounting for the outstanding BioTime Warrants as a liability at fair value, with subsequent changes to the fair value of the BioTime Warrants at each reporting period thereafter included in the consolidated statement of operations (see Note 3).

For the three and six months ended months ended June 30, 2019, BioTime recorded an unrealized gain of $0.2 million due to the decline in the fair value of the BioTime Warrants from the Asterias Merger date through June 30, 2019. As of June 30, 2019, the fair value of the BioTime Warrants was $0.3 million included in long-term liabilities on the condensed consolidated balance sheets.

Cell Cure Warrants - Liability Classified

Cell Cure has two sets of issued warrants. Warrants to purchase 24,566 Cell Cure ordinary shares at an exercise price of $40.5359 were issued to Hadasit in July 2017. These warrants expire in July 2022. Warrants to purchase 13,738 Cell Cure ordinary shares at exercise prices ranging from $32.02 to $40.00 per share have been issued to consultants. These warrants expire in October 2020 and January 2024.

ASC 815 requires freestanding financial instruments, such as warrants, with exercise prices denominated in currencies other than the functional currency of the issuer to be accounted for as liabilities at fair value, with all subsequent changes in fair value after the issuance date to be recorded as gains or losses in the consolidated statements of operations.

As of June 30, 2019 and December 31, 2018, the total value of all warrants issued by Cell Cure was $0.3 million and $0.4 million, respectively. Such warrants are classified as long-term liabilities on the condensed consolidated balance sheets.

12. Stock-Based Awards

Equity Incentive Plan Awards

BioTime adopted a 2012 Equity Incentive Plan (the “2012 Plan”) for the grant of stock options, restricted stock, restricted stock units and stock appreciation rights. As of June 30, 2019, a maximum of 16,000,000 common shares were available for grant; this amount was increased to 24,000,000 common shares on July 30, 2019 when shareholder approval was obtained.

A summary of BioTime’s 2012 Plan activity and other stock option awards granted outside of the 2012 Plan related information is as follows (in thousands, except per share amounts):

	Shares Available for Grant			Number of Options Outstanding			Number of RSUs Outstanding			Weighted Average Exercise Price
December 31, 2018		1,885			13,867			402		$	2.44

Options exercisable at June 30, 2019					9,213					$	2.59

26

At the effective time of the Asterias Merger, BioTime assumed sponsorship of the Asterias 2013 Equity Incentive Plan (the “Asterias Equity Plan”), with references to Asterias and Asterias common stock therein to be deemed references to BioTime and BioTime common stock. There were 7,309,184 shares available under the Asterias Equity Plan immediately before the closing of the Asterias Merger, which became 5,189,520 shares immediately following the Asterias Merger. The shares available under the Asterias Equity Plan will be for awards granted to those former Asterias employees who continued as BioTime employees upon consummation of the Asterias Merger. A summary of activity under the Asterias Equity Plan from the closing date of the Asterias Merger through June 30, 2019 is as follows (in thousands, except per share amounts):

	Shares Available for Grant			Number of Options Outstanding			Number of RSUs Outstanding		Weighted Average Exercise Price
March 8, 2019		5,190			-			-	$	-
Options granted		(490	)		490			-		1.59

Stock-based compensation expense

The fair value of each option award is estimated on the date of grant using a Black-Scholes option pricing model applying the weighted-average assumptions noted in the following table:

	Six Months Ended June 30, (unaudited)
	2019			2018
Expected life (in years)		6.06			5.87
Risk-free interest rates		2.5	%		2.6	%
Volatility		60.2	%		56.1	%
Dividend yield		-	%		-	%

Operating expenses include stock-based compensation expense as follows (in thousands):

	Three Months Ended June 30, (unaudited)				Six Months Ended June 30, (unaudited)
	2019		2018		2019		2018
Research and development	$	161	$	188	$	283	$	381
General and administrative		601		915		1,919		1,706
Total stock-based compensation expense	$	762	$	1,103	$	2,202	$	2,087

The expense related to 84,940 shares of Asterias restricted stock unit awards that immediately vested on the closing of the Asterias Merger and converted into the right to receive shares of BioTime common stock based on the Merger Exchange Ratio, resulting in 60,304 shares of BioTime common stock issued on March 8, 2019, which were included in stock-based compensation expense for the six months ended June 30, 2019. The expense was not included as part of the purchase price of the Asterias Merger because these awards were principally attributable to post-combination services.

13. Income Taxes

The provision for income taxes for interim periods is generally determined using an estimated annual effective tax rate as prescribed by ASC 740-270, Income Taxes, Interim Reporting. The effective tax rate may be subject to fluctuations during the year as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as valuation allowances and changes in valuation allowances against deferred tax assets, the recognition or de-recognition of tax benefits related to uncertain tax positions, if any, and changes in or the interpretation of tax laws in jurisdictions where BioTime conducts business. ASC 740-270 also states that if an entity is unable to reliably estimate some or a part of its ordinary income or loss, the income tax provision or benefit applicable to the item that cannot be estimated shall be reported in the interim period in which the item is reported.

For items that BioTime cannot reliably estimate on an annual basis (principally unrealized gains or losses generated by changes in the market prices of the OncoCyte, and AgeX shares of common stock BioTime holds, and prior to March 8, 2019, Asterias shares BioTime held), BioTime uses the actual year to date effective tax rate rather than an estimated annual effective tax rate to determine the tax effect of each item, including the use of all available net operating losses and other credits or deferred tax assets.

27

Although the deconsolidation of OncoCyte was not a taxable transaction to BioTime and did not create a current income tax payment obligation to BioTime, the market value of the shares of OncoCyte common stock BioTime holds creates a deferred tax liability to BioTime based on the closing prices of the shares, less BioTime’s tax basis in the shares. The deferred tax liability generated by the OncoCyte shares that BioTime holds as of June 30, 2019, is a source of future taxable income to BioTime, as prescribed by ASC 740-10-30-17, that will more likely than not result in the realization of its deferred tax assets to the extent of the deferred tax liability. This deferred tax liability is determined based on the closing prices of the OncoCyte shares as of June 30, 2019. Due to the inherent unpredictability of future prices of those shares, BioTime cannot reliably estimate or project those deferred tax liabilities on an annual basis. Therefore, the deferred tax liability pertaining to OncoCyte shares, determined based on the actual closing prices on the last stock market trading day of the applicable accounting period, and the related impacts to the valuation allowance and deferred tax asset changes, are recorded in the accounting period in which they occur.

Prior to the Asterias Merger discussed in Note 3, the Asterias shares of common stock BioTime held generated similar deferred tax liabilities to BioTime as the OncoCyte shares discussed above. As of the Asterias Merger date and due to Asterias becoming a wholly owned subsidiary of BioTime, the Asterias deferred tax liabilities were eliminated with a corresponding adjustment to BioTime’s valuation allowance, resulting in no tax provision or benefit from this adjustment.

On March 23, 2018, Ascendance was acquired by a third party in a merger through which AgeX received approximately $3.2 million in cash for its shares of Ascendance common stock. For financial reporting purposes, AgeX recognized a $3.2 million gain as a sale of its equity method investment in Ascendance. The sale was a taxable transaction to AgeX generating a taxable gain of approximately $2.2 million. BioTime had sufficient losses from operations to offset the entire gain resulting in no income taxes due.

The income tax consequences of the AgeX Deconsolidation are discussed below.

The Juvenescence Transaction discussed in Note 5 was a taxable event for BioTime that resulted in a gross taxable gain of approximately $29.4 million, which BioTime fully offset with available net operating losses (“NOL”) and NOL carryforwards, resulting in no net income taxes due. Although the AgeX Deconsolidation on August 30, 2018 was not a taxable transaction to BioTime and did not result in a current tax payment obligation, the unrealized financial reporting gain (see Note 6) on the AgeX Deconsolidation generated a deferred tax liability in accordance with ASC 740, primarily representing BioTime’s difference between book and tax basis of AgeX common stock on the AgeX Deconsolidation date. This deferred tax liability was fully offset by a corresponding release of BioTime’s valuation allowance on deferred tax assets, resulting in no income tax provision or benefit from the AgeX Deconsolidation. The deferred tax liabilities on BioTime’s investments in OncoCyte, Asterias and AgeX are considered to be sources of taxable income as prescribed by ASC 740-10-30-17 that will more likely than not result in the realization of its deferred tax assets to the extent of those deferred tax liabilities, thereby reducing the need for a valuation allowance.

The distribution of AgeX shares of common stock to BioTime shareholders (see Note 6) on November 28, 2018 was a taxable event for BioTime that resulted in a gross taxable gain of approximately $26.4 million, which was fully offset by NOL carryforwards, resulting in no income taxes due.

In connection with the Asterias Merger, a deferred tax liability of $13.0 million was recorded as part of the acquisition accounting (see Note 3). The deferred tax liability (“DTL”) is related to fair value adjustments for the assets and liabilities acquired in the Asterias Merger, principally consisting of IPR&D. This estimate of deferred taxes was determined based on the excess of the estimated fair values of the acquired assets and liabilities over the tax basis of the assets and liabilities acquired. The statutory tax rate was applied, as appropriate, to the adjustment based on the jurisdiction in which the adjustment is expected to occur. This estimate of deferred income tax liabilities is preliminary and is subject to change based upon BioTime’s final determination of the fair value of assets acquired and liabilities assumed. Because the IPR&D (prior to completion or abandonment of the R&D) is considered an indefinite-lived asset for accounting purposes, the fair value of the IPR&D on the acquisition date creates a deferred income tax liability in accordance with ASC 740. This DTL is computed using the fair value of the IPR&D assets on the acquisition date multiplied by BioTime’s respective federal and state income tax rates. While this DTL would reverse on impairment or sale or commencement of amortization of the related intangible assets, those events are not anticipated under ASC 740 for purposes of predicting reversal of a temporary difference to support the realization of deferred tax assets, except for certain deferred tax assets and credit carryforwards that are also indefinite in nature as of the Asterias Merger date, which may be considered for reversal under ASC 740 as further discussed below.

A valuation allowance is provided when it is more likely than not that some portion of the deferred tax assets will not be realized. For federal and state income tax purposes, as a result of the deconsolidation of AgeX, Asterias and OncoCyte and the deferred tax liabilities generated from the market values of AgeX, Asterias and OncoCyte shares from the respective deconsolidation dates, including the changes to those deferred tax liabilities due to changes in the AgeX, Asterias and OncoCyte stock prices, BioTime’s deferred tax assets exceeded its deferred tax liabilities as of December 31, 2018. As a result, BioTime established a full valuation allowance as of December 31, 2018 due to the uncertainty of realizing future tax benefits from its net operating loss carryforwards and other deferred tax assets.

28

For the three and six months ended June 30, 2019, BioTime reversed a portion of its valuation allowance. The partial reversal of the historical valuation allowance is related to BioTime’s deferred tax assets and credit carryforwards and is due to the acquired taxable temporary differences, primarily consisting of the acquired IPR&D discussed above and in Notes 3 and 8. ASC 740 allows for deferred tax assets and credit carryforwards, that are both available and indefinite in nature, to be used against similar deferred tax liabilities as a source of income to support the realization of those deferred tax assets and credit carryforwards. Any benefit recognized from such a reversal of the valuation allowance is recorded outside of the acquisition accounting. Accordingly, the $1.2 million and $5.6 million valuation allowance release and the corresponding tax benefits were primarily related to state research and development credits, including current year federal net operating losses generated for the three and six months ended June 30, 2019, respectively, both of which are available and indefinite in nature.

BioTime did not record any provision or benefit for income taxes for the three and six months ended June 30, 2018 as BioTime had a full valuation allowance for the periods presented.

15. Commitments and Contingencies

Alameda Lease

In December 2015, BioTime entered into a lease for approximately 30,795 square feet of rentable space in two buildings located in an office park in Alameda, California (the “Alameda Lease”). The term of the Alameda Lease commenced effective February 1, 2016 and expires on January 31, 2023, unless BioTime exercises its option to renew the lease for an additional five years.

Base rent under the Alameda Lease beginning on February 1, 2019 is $70,521 per month and will increase by approximately 3% annually on every February 1 thereafter during the lease term.

Prior to the adoption of ASC 842 on January 1, 2019 (see Note 2), the lease payments allocated to the lease liability for leasehold improvements reimbursed by the landlord were amortized as debt service on that liability using the effective interest method over the lease term.

See Note 2 for discussion of the impact of adoption of ASC 842 on January 1, 2019, and below for the ROU assets and liabilities recorded in connection with the adoption of ASC 842 as of, and during the six months ended June 30, 2019 for the Alameda Lease.

In addition to base rent, BioTime will pay a pro rata portion of increases in certain expenses, including real property taxes, utilities (to the extent not separately metered to the leased space) and the landlord’s operating expenses, over the amounts of those expenses incurred by the landlord. As security for the performance of its obligations under the Alameda Lease, BioTime provided the landlord with a security deposit of approximately $424,000, which was reduced to $78,000 on January 24, 2019 in accordance with the terms of the lease. The security deposit amount is considered restricted cash and $78,000 is included in deposits and other long-term assets as of June 30, 2019 (see Note 2).

Carlsbad Lease

In May 2019, BioTime entered into a lease for approximately 8,841 square feet of rentable space in an office park in Carlsbad, California (the “Carlsbad Lease”). The term of the Carlsbad Lease commenced on August 1, 2019 and expires on October 31, 2022.

Base rent under the Carlsbad Lease beginning on August 1, 2019 is $17,850 per month and will increase by 3% annually on every August 1 thereafter during the lease term. Base rent for the first twenty-four months of the lease is based upon a deemed rentable area of 7,000 square feet. Base rent is abated for months two through five of the lease.

In addition to base rent, BioTime will pay a pro rata portion of increases in certain expenses, including real property taxes, utilities (to the extent not separately metered to the leased space) and the landlord’s operating expenses, over the amounts of those expenses incurred by the landlord. As security for the performance of its obligations under the Alameda Lease, BioTime provided the landlord with a security deposit of approximately $17,850.

29

New York Leased Office Space

BioTime currently pays $5,050 per month for the use of approximately 900 square feet of office space in New York City, which is made available to BioTime for use in conducting meetings and other business affairs, on a month-by-month basis, by one of its directors at an amount that approximates his cost. This lease was not in the scope of ASC 842 because it is a month to month lease (see Note 2).

Cell Cure Lease

Cell Cure leases 728.5 square meters (approximately 7,842 square feet) of office and laboratory space in Jerusalem, Israel under a lease that expires December 31, 2020, with two options to extend the lease for 5 years each. Base monthly rent is NIS 37,882 (approximately US $11,000 per month using the December 31, 2018 exchange rate). In addition to base rent, Cell Cure pays a pro rata share of real property taxes and certain costs related to the operation and maintenance of the building in which the leased premises are located.

On January 28, 2018, Cell Cure entered into another lease agreement for an additional 934 square meters (approximately 10,054 square feet) of office space in the same facility in Jerusalem, Israel under a lease that expires on December 31, 2025, with two options to extend the lease for 5 years each (the “January 2018 Lease”). The January 2018 Lease commenced on April 1, 2018 and included a leasehold improvement construction allowance of up to NIS 4,000,000 (approximately up to $1.1 million using the December 31, 2018 exchange rate) from the landlord. The leasehold improvements were completed in December 2018 and the entire allowance was used. Beginning on January 1, 2019, combined base rent and construction allowance payments for the January 2018 Lease are NIS 93,827 per month (approximately $26,000 per month).

Prior to the adoption of ASC 842 on January 1, 2019, Cell Cure was considered the owner of the tenant improvements under construction under ASC 840-40-55 as Cell Cure, among other things, had the primary obligation to pay for construction costs and Cell Cure retains exclusive use of the leased facilities for its office, research and cGMP manufacturing facility requirements after construction was completed (“build to suit” lease). In accordance with the ASC 840 guidance, amounts expended by Cell Cure for construction was reported as construction in progress, and the proceeds received from the landlord, if any, are reported as a lease liability. As of December 31, 2018, approximately $1.1 million under the January 2018 Lease was incurred and recorded as leasehold improvement construction in progress (see Note 7), with a corresponding amount included in long term lease liability representing the full amount utilized from the landlord’s leasehold improvement construction allowance. By March 2019, the landlord paid the complete leasehold improvement construction allowance and the property was placed in service.

See Note 2 discussion of the impact of adoption of ASC 842 on January 1, 2019, and below for the ROU assets and liabilities recorded in connection with the adoption of ASC 842 as of, and during the six months ended June 30, 2019 for the Cell Cure and January 2018 Leases above (the “Cell Cure Leases”).

In December 2018, Cell Cure made a $388,000 deposit required under the January 2018 Lease, which amount is included in deposits and other long-term assets on the consolidated balance sheet as of December 31, 2018, to be held as restricted cash during the term of the January 2018 Lease.

Research and Option Agreement

On January 5, 2019, BioTime and Orbit Biomedical Limited (“Orbit”) entered into a Research and Option Agreement (the “Orbit Agreement”) for an exclusive partnership to assess Orbit’s vitrectomy-free subretinal injection device as a means of delivering OpRegen in BioTime’s ongoing Phase I/IIa clinical trial. The term of the Orbit Agreement is for one year unless certain research activities and related data specified in the Orbit Agreement is obtained sooner. The access fees payable by BioTime to Orbit for its technology and the injection device are $2.5 million in the aggregate, of which $1.25 million was paid in January 2019 upon execution of the Orbit Agreement and the remaining $1.25 million payment is due on the earlier of (i) six months from the Orbit Agreement date or, (ii) upon completion of certain collaborative research activities using the Orbit technology for the OpRegen Phase I/IIa clinical trial, as specified in the Orbit Agreement. In addition to the access fees, BioTime will pay Orbit for costs of consumables, training services, travel costs and other out of pocket expenses incurred by Orbit for performing services under the Orbit Agreement. BioTime has exclusive rights to the Orbit technology and its injection device for the treatment of dry-AMD during the term of the Orbit Agreement and may extend the term for an additional three months by paying Orbit a cash fee of $500,000. For the three and six months ended June 30, 2019, BioTime amortized $0.6 million and $1.25 million of the upfront payment fee included in research and development expenses. As of June 30, 2019, BioTime had not incurred the remaining $1.25 million access fee. In July 2019, BioTime completed the collaborative research activities referred to above and the second $1.25 million payment will be made in August 2019.

Litigation

BioTime will be subject to various claims and contingencies in the ordinary course of its business, including those related to litigation, business transactions, employee-related matters, and others. When BioTime is aware of a claim or potential claim, it assesses the likelihood of any loss or exposure. If it is probable that a loss will result and the amount of the loss can be reasonably estimated, BioTime will record a liability for the loss. If the loss is not probable or the amount of the loss cannot be reasonably estimated, BioTime will disclose the claim if the likelihood of a potential loss is reasonably possible and the amount involved could be material. BioTime is not aware of any claims likely to have a material adverse effect on its financial condition or results of operations.

On February 19, 2019, a putative shareholder class action lawsuit was filed (captioned Lampe v. Asterias Biotherapeutics, Inc. et al., Case No. RG19007391) in the Superior Court of the State of California, County of Alameda challenging the Asterias Merger. On March 1, 2019, Asterias made certain amendments and supplements to its public disclosures regarding the Asterias Merger (the “Supplemental Disclosures”). On May 3, 2019, an amended class action complaint (the “Amended Complaint”) was filed. The Amended Complaint names BioTime, Patrick Merger Sub, Inc., the Asterias board of directors, one member of BioTime’s board of directors, and certain stockholders of both BioTime and Asterias. The action was brought by two purported stockholders of Asterias, on behalf of a putative class of Asterias stockholders, and asserts breach of fiduciary duty and aiding and abetting claims under Delaware law. The Amended Complaint alleges, among other things, that the process leading up to the Asterias Merger was conflicted and inadequate, and that the proxy statement filed by Asterias with the Securities and Exchange Commission omitted certain material information, which allegedly rendered the information disclosed materially misleading. The Amended Complaint seeks, among other things, that a class be certified, the recovery of monetary damages, and attorneys’ fees and costs.

On June 3, 2019, defendants filed demurrers to the Amended Complaint. Plaintiffs’ counsel subsequently indicated that, after reviewing the demurrers and analyzing certain documents produced by defendants, Plaintiffs wished to voluntarily dismiss the action with prejudice as to themselves, and without prejudice as to the unnamed putative class members. Plaintiffs’ counsel also indicated that, independent of their decision to voluntarily dismiss the action, Plaintiffs believe they have a claim for attorneys’ fees and expenses in connection with the purported benefit conferred on Asterias stockholders by the Supplemental Disclosures (the “Fee Claim”). On July 26, 2019, the parties entered into a stipulation to stay the briefing schedule on the demurrers and to take the hearing on the demurrers off calendar so that the parties could discuss the Fee Claim (the “Stipulation”). On July 29, 2019, the Court entered the Stipulation as an order, took the demurrer hearing off calendar, and set a case management conference for September 17, 2019. Thereafter, the parties began negotiating the Fee Claim and, on August 5, 2019, agreed in principle to resolve the Fee Claim for $200,000. The parties intend to submit a stipulation to the Court seeking dismissal of the action with prejudice as to the named Plaintiffs and without prejudice as to the unnamed putative class members, and seeking approval of the negotiated Fee Claim. BioTime continues to believe that the claims and allegations in the action lack merit, but believes that it is in BioTime’s shareholders’ best interest for the action to be dismissed and to resolve the Fee Claim in a timely manner without additional costly litigation expenses.

Employment contracts

BioTime has entered into employment agreements with certain executive officers. Under the provisions of the agreements, BioTime may be required to incur severance obligations for matters relating to changes in control, as defined in the agreements, and involuntary terminations.

Indemnification

In the normal course of business, BioTime may provide indemnifications of varying scope under BioTime’s agreements with other companies or consultants, typically BioTime’s clinical research organizations, investigators, clinical sites, suppliers and others. Pursuant to these agreements, BioTime will generally agree to indemnify, hold harmless, and reimburse the indemnified parties for losses and expenses suffered or incurred by the indemnified parties arising from claims of third parties in connection with the use or testing of BioTime’s products and services. Indemnification provisions could also cover third party infringement claims with respect to patent rights, copyrights, or other intellectual property pertaining to BioTime products and services. The term of these indemnification agreements will generally continue in effect after the termination or expiration of the particular research, development, services, or license agreement to which they relate. The potential future payments BioTime could be required to make under these indemnification agreements will generally not be subject to any specified maximum amount. Historically, BioTime has not been subject to any claims or demands for indemnification. BioTime also maintains various liability insurance policies that provide BioTime with insurance against claims or demands for indemnification in specified circumstances. As a result, BioTime believes the fair value of these indemnification agreements is minimal. Accordingly, BioTime has not recorded any liabilities for these agreements as of June 30, 2019 and December 31, 2018.

Royalty obligations and license fees

BioTime and its subsidiaries or affiliates are parties to certain licensing agreements with research institutions, universities and other parties for the rights to use those licenses and other intellectual property in conducting research and development activities. These licensing agreements provide for the payment of royalties by BioTime or the applicable party to the agreement on future product sales, if any. In addition, in order to maintain these licenses and other rights during the product development, BioTime or the applicable party to the contract must comply with various conditions including the payment of patent related costs and annual minimum maintenance fees. Annual minimum maintenance fees are approximately $135,000 to $150,000 per year. The research and development risk for these products is significant. License fees and related expenses under these agreements were immaterial for the periods presented in the condensed consolidated interim financial statements provided herein.

32

Grants

Under the terms of the grant agreement between Cell Cure and Israel Innovation Authority (“IIA”) (formerly the Office of the Chief Scientist of Israel) of the Ministry of Economy and Industry, for the development of OpRegen ^® , Cell Cure will be required to pay royalties on future product sales, if any, up to the amounts received from the IIA, plus interest indexed to LIBOR. Cell Cure’s research and product development activities under the grant are subject to substantial risks and uncertainties and performed on a best efforts basis. As a result, Cell Cure is not required to make any payments under the grant agreement unless it successfully commercializes OpRegen. Accordingly, pursuant to ASC 730-20, the grant is considered a contract to perform research and development services for others and grant revenue is recognized as the related research and development expenses are incurred (see Note 2).

Israeli law pertaining to such government grants contain various conditions, including substantial penalties and restrictions on the transfer of intellectual property, or the manufacture, or both, of products developed under the grant outside of Israel, as defined by the IIA.

16. Subsequent Events

In July 2019, BioTime sold 2,250,000 shares of common stock of OncoCyte for net proceeds of $4.2 million and recorded a realized loss on sale of $1.4 million, including commissions and fees. Following the completion of the sale, BioTime owns approximately 23.9% or 12.4 million shares of OncoCyte’s outstanding common stock.

In July 2019, BioTime sold 647,397 shares of common stock of Hadasit for net proceeds of approximately $1.2 million and recorded a realized gain on sale of $0.3 million, including commissions and fees. Following the completion of the sale, BioTime owns approximately 8.1% or 0.9 million shares of Hadasit’s outstanding common stock.

On July 30, 2019, BioTime conducted its annual shareholder meeting and received shareholder approval to increase the maximum common shares available for grant under the 2012 Equity Incentive Plan from 16,000,000 common shares to 24,000,000 common shares.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The matters addressed in this Item 2 that are not historical information constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, including statements about any of the following: any projections of earnings, revenue, gross profit, cash, effective tax rate, use of net operating losses, or any other financial items; the plans, strategies and objectives of management for future operations or prospects for achieving such plans; and any statements of assumptions underlying any of the foregoing. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Without limiting the foregoing, the words “believes,” “anticipates,” “plans,” “expects,” “seeks,” “estimates,” and similar expressions are intended to identify forward-looking statements. While BioTime may elect to update forward-looking statements in the future, it specifically disclaims any obligation to do so, even if BioTime’s estimates change, and readers should not rely on those forward-looking statements as representing BioTime’s views as of any date subsequent to the date of the filing of this Quarterly Report. Although we believe that the expectations reflected in these forward-looking statements are reasonable, such statements are inherently subject to risks and BioTime can give no assurances that its expectations will prove to be correct. Actual results could differ materially from those described in this Quarterly Report because of numerous factors, many of which are beyond the control of BioTime. A number of important factors could cause the results of the company to differ materially from those indicated by such forward-looking statements, including those detailed under the heading “Risk Factors” in Part I, Item 1A of BioTime’s Form 10-K for the year ended December 31, 2018.

The following discussion should be read in conjunction with BioTime condensed consolidated interim financial statements and the related notes provided under “Item 1- Financial Statements” above.

Company and Business Overview

BioTime is a clinical-stage biotechnology company developing novel cell therapies for unmet medical needs. Our current focus is on therapies for degenerative retinal diseases, neurological conditions associated with demyelination, and aiding the body in detecting and combating cancer. BioTime’s programs are based on our proprietary cell-based therapy platform and associated development and manufacturing capabilities. With this platform, BioTime develops and manufactures specialized, terminally-differentiated human cells from our pluripotent and progenitor cell starting materials. These differentiated cells are developed either to replace or support cells that are dysfunctional or absent due to degenerative disease or traumatic injury, or are administered as a means of helping the body mount an effective immune response to cancer.

We have three cell therapy programs in clinical development:

● OpRegen^®, a retinal pigment epithelium cell replacement therapy currently in a Phase I/IIa multicenter clinical trial for the treatment of advanced dry age-related macular degeneration (“dry-AMD”) with geographic atrophy (“OpRegen trial”). Dry-AMD accounts for approximately 85-90% of all age-related macular degeneration cases and is a leading cause of blindness in people over the age of 65. There currently are no therapies approved by the U.S. Food and Drug Administration (“FDA”) for dry-AMD.

● OPC1, an oligodendrocyte progenitor cell therapy currently in a Phase I/IIa multicenter clinical trial for acute spinal cord injuries. This clinical trial has been partially funded by the California Institute for Regenerative Medicine.

● VAC2, an allogeneic (non-patient-specific or “off-the-shelf”) cancer immunotherapy of antigen-presenting dendritic cells currently in a Phase I clinical trial in non-small cell lung cancer. This clinical trial is being funded and conducted by Cancer Research UK, the world’s largest independent cancer research charity.

We also have cell/drug delivery programs based upon our proprietary HyStem^® cell and drug delivery matrix technology. HyStem was designed to support the formulation, transfer, retention, and engraftment of cellular therapies. We also established and support multiple collaborations with both academic and for-profit partners to develop HyStem for additional therapeutic uses, and we sell both research and GMP-grade HyStem to support additional external research and development activities.

Our lead cell delivery clinical program is Renevia^®, a medical device developed as a replacement for whole adipose tissue in cell assisted lipotransfer (CAL) procedures. In a European pivotal clinical trial in patients with HIV-associated facial lipoatrophy, the primary endpoint of change in hemifacial volume at 6 months in treated patients compared to patients in the delayed treatment arm as measured by three-dimensional photographic volumetric assessment was met. In 2018, we submitted a design dossier for EU market clearance (CE Mark) for the use of Renevia as a device to aid in transferring a patient’s own adipose tissue to treat certain forms of facial lipoatrophy, or fat loss. We have ongoing discussions with our European notified body and are currently awaiting notification as to its status. We expect to receive a decision from the notified body in the second half of 2019.

We completed our acquisition of the remaining ownership interests in Asterias Biotherapeutics, Inc. on March 8, 2019. We added OPC1 and VAC2 to our cell therapy product portfolio as a result of that acquisition.

34

We have equity holdings in two publicly traded companies: OncoCyte Corporation (“OncoCyte”) (approximately 24% ownership) and AgeX Therapeutics, Inc. (“AgeX”) (approximately 5% ownership). We founded both companies and they were majority-owned and consolidated subsidiaries. OncoCyte (NYSE American: OCX) is developing confirmatory diagnostic tests for lung cancer utilizing novel liquid biopsy technology, and AgeX (NYSE American: AGE) is focused on the development of early-stage programs relating to cell immortality, regenerative biology, aging, and age-related diseases.

Critical Accounting Policies

This Management’s Discussion and Analysis of Financial Condition and Results of Operations discusses and analyzes data in our unaudited Condensed Consolidated Interim Financial Statements, which we have prepared in accordance with GAAP. Preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Management bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Senior management has discussed the development, selection and disclosure of these estimates with the Audit Committee of our Board of Directors. Actual conditions may differ from our assumptions and actual results may differ from our estimates.

An accounting policy is deemed critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, if different estimates reasonably could have been used, or if changes in the estimate that are reasonably likely to occur could materially impact the financial statements. Management believes that there have been no significant changes during the three and six months ended June 30, 2019 to the items that we disclosed as our critical accounting policies and estimates in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2018, except as follows:

Leases

We account for leases in accordance with Accounting Standards Codification, (“ASC”) 842, Leases. We determine if an arrangement is a lease at inception. Leases are classified as either financing or operating, with classification affecting the pattern of expense recognition in the consolidated statements of operations. Under the available practical expedients for the adoption of ASC 842, we account for the lease and non-lease components as a single lease component. We recognize right-of-use (“ROU”) assets and lease liabilities for leases with terms greater than twelve months in the condensed consolidated balance sheet.

ROU assets represent our right to use an underlying asset during the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Operating leases are included as right-of-use assets in property and equipment, and ROU lease liabilities, current and long-term, in the condensed consolidated balance sheets. Financing leases are included in property and equipment, and in financing lease liabilities, current and long-term, in the condensed consolidated balance sheets.

Business Combinations

We account for business combinations, such as the Asterias Merger completed in March 2019, in accordance with ASC Topic 805, Business Combinations , which requires the purchase price to be measured at fair value. When the purchase consideration consists entirely of shares of our common stock, we calculate the purchase price by determining the fair value, as of the acquisition date, of shares issued in connection with the closing of the acquisition. We recognize estimated fair values of the tangible assets and intangible assets acquired, including in-process research and development (“IPR&D”), and liabilities assumed as of the acquisition date, and we record as goodwill any amount of the fair value of the tangible and intangible assets acquired and liabilities assumed in excess of the purchase price.

Goodwill and IPR&D

Goodwill is calculated as the difference between the acquisition date fair value of the consideration transferred and the values assigned to the assets acquired and liabilities assumed. Goodwill is not amortized but is tested for impairment at least annually, or more frequently if circumstances indicate potential impairment.

35

IPR&D assets are indefinite-lived intangible assets until the completion or abandonment of the associated research and development (“R&D”) efforts. Once the R&D efforts are completed or abandoned, the IPR&D will either be amortized over the asset life as a finite-lived intangible asset or be impaired, respectively, in accordance with ASC 350, Intangibles - Goodwill and Other. In accordance with ASC 350, goodwill and acquired IPR&D are determined to have indefinite lives and, therefore, are not amortized. Instead, they are tested for impairment at least annually and between annual tests if we become aware of an event or a change in circumstances that would indicate the asset may be impaired.

Results of Operations

Comparison of Three and Six Months Ended June 30, 2019 and 2018

Revenues and Cost of Sales

The amounts in the tables below show our consolidated revenues, by source, and cost of sales for the periods presented (in thousands).

Gross profit	$	1,532		$	3,032		$	(1,500	)		(49	)%

Our total revenues decreased by $1.8 million for the three months ended June 30, 2019 as compared to the same period in the prior year, primarily reflecting a $1.4 million decrease in grant revenues and a $0.3 million decrease in subscriptions and advertisement revenues.

Our total revenues decreased by $1.5 million for the six months ended June 30, 2019 as compared to the same period in the prior year, primarily reflecting a $1.0 million decrease in grant revenues and a $0.6 million decrease in subscriptions and advertisement revenues.

Our grant revenues are generated primarily by Cell Cure from the IIA for the development of OpRegen^® and from a Small Business Innovation Research grant from the National Institutes of Health for our vision restoration program (the “NIH grant”). The decreases in our grant revenues for the three and six months ended June 30, 2019 as compared to the same periods in the prior year, were primarily due to timing of grant payments. Grant revenues generated by Cell Cure from the IIA for the development of OpRegen amounted to $0.5 million and $0.9 million for the three and six months ended June 30, 2019, respectively, and grant revenues generated by the NIH grant amounted to $0.1 million and $0.4 million for the three and six months ended June 30, 2019, respectively.

Our subscription and advertising revenues, including certain service revenues, were generated entirely by LifeMap Sciences, AgeX’s majority-owned subsidiary and are included in our revenues prior to the AgeX Deconsolidation. As a result, the decrease in those revenues is due to the AgeX Deconsolidation on August 30, 2018. Due to the AgeX Deconsolidation, we do not expect to earn subscription and advertising revenues in future periods.

36

Revenues from the sale of research products and services are primarily derived from service revenues and the sale of hydrogels and stem cell products.

The transaction was considered an asset acquisition rather than a business combination. Accordingly, the $800,000 was expensed on the acquisition date as acquired in-process research and development as those assets have no alternative future use.
(5)	LifeMap Sciences is a subsidiary of AgeX. Research and development expenses shown for the periods presented in 2018 are prior to the AgeX Deconsolidation.

The decrease of $1.1 million in total research and development expenses for the three months ended June 30, 2019 as compared to the same period in the prior year is mainly attributable to the following: decreases of $1.4 million in AgeX related programs, including LifeMap Sciences, due to the AgeX Deconsolidation on August 30, 2018, offset by a net increase of $0.3 million in BioTime programs primarily related to: (1) an increase of $1.7 million in OPC1 and VAC2 expenses (these programs were acquired in the Asterias Merger), offset by (2) decreases of $1.4 million in Renevia, HyStem and PureStem related expenses.

The decrease of $2.9 million in total research and development expenses for the six months ended June 30, 2019 as compared to the same period in the prior year is mainly attributable to the following: decreases of $3.0 million in AgeX related programs, including LifeMap Sciences, due to the AgeX Deconsolidation on August 30, 2018, and $0.8 million related to the absence of a nonrecurring $0.8 million expense incurred by AgeX on March 23, 2018 with respect to certain acquired in-process research and development assets that have no alternative future uses, offset by a net increase of $0.9 million in BioTime programs primarily related to: (1) an increase of $2.3 million in OPC1 and VAC2 expenses (these programs were acquired in the Asterias Merger), (2) an increase of $0.8 million in OpRegen related expenses, offset by (3) decreases of $2.3 million in Renevia, HyStem and PureStem related expenses.

(4)	LifeMap Sciences is a subsidiary of AgeX. General and administrative expenses shown for the periods presented in 2018 are prior to the AgeX Deconsolidation.

The total net increase of $1.0 million in general and administrative expense for the three months ended June 30, 2019 compared to the same period in 2018, was primarily attributable to a $1.9 million increase in severance, legal, accounting and other expenses related to the Asterias Merger which was offset by a $1.1 million decrease in AgeX related general and administrative expenses.

The total net increase of $3.8 million in general and administrative expense for the six months ended June 30, 2019 compared to the same period in 2018, was primarily attributable to a $5.8 million increase in severance, legal, accounting and other expenses related to the Asterias Merger, a $0.5 million increase in BioTime stock-based compensation expenses due to new equity awards granted in 2019 and a $0.3 million increase in rent expense which is primarily related to the adoption of new lease guidance; these increases were partially offset by a $2.4 million decrease in AgeX related general and administrative expenses and a $0.5 million decrease in legal and accounting fees.

General and administrative expenses include employee and director compensation allocated to general and administrative expenses, consulting fees other than those paid for science or research related consulting, facilities and equipment rent and maintenance related expenses, insurance costs allocated to general and administrative expenses, stock exchange-related costs, depreciation expense, marketing costs, legal, compliance and accounting costs, and other miscellaneous expenses which are allocated to general and administrative expense.

Gain (loss) on equity method investment in OncoCyte – As of June 30, 2019, we owned 14.7 million shares of common stock of OncoCyte. We elected to account for our shares in OncoCyte at fair value using the equity method of accounting beginning on February 17, 2017, the date of the OncoCyte Deconsolidation. Our OncoCyte shares had a fair value of $36.5 million, $58.0 million and $20.3 million as of June 30, 3019, March 31, 2019 and December 31, 2018, respectively, based on the closing price of OncoCyte common stock on the NYSE American of $2.49 per share, $3.95 per share and $1.38 per share, respectively, on those dates or the last trading day of the applicable quarter. Accordingly, we recorded an unrealized loss of $21.4 million and an unrealized gain of $16.3 million for the three and six months ended June 30, 2019, respectively. Our OncoCyte shares had a fair value of $37.4 million, $30.8 million and $68.2 million as of June 30, 2018, March 31, 2018 and December 31, 2017, respectively, based on the closing price of OncoCyte common stock on the NYSE American of $2.55 per share, $2.10 per share and $4.65 per share, respectively, on those dates or the last trading day of the quarter. Accordingly, we recorded an unrealized gain of $6.6 million and an unrealized loss of $30.8 million for the three and six months ended June 30, 2018.

Gain (loss) on equity method investment in Asterias shares - Prior to the closing of the Asterias Merger on March 8, 2019, where we acquired 100% of its outstanding shares, we owned 21.7 million shares of common stock of Asterias. We elected to account for our shares in Asterias at fair value using the equity method of accounting beginning on May 13, 2016, the date of the Asterias Deconsolidation. The fair value of our Asterias shares was approximately $20.2 million as of March 8, 2019, the closing date of the Asterias Merger, based on $0.93 per share, which was calculated by multiplying (a) $1.31, the closing price of our common stock on such date by (b) the Merger Exchange Ratio. The fair value of our Asterias shares was approximately $13.5 million as of December 31, 2018, based on the closing price of Asterias common stock of $0.62 per share on such date. Accordingly, we recorded an unrealized gain of $6.7 million for both the three and six months ended June 30, 2019, representing the change in fair value of Asterias common stock from December 31, 2018 to March 8, 2019. Our Asterias shares had a fair value of $29.4 million, $31.5 million and $48.9 million as of June 30, 2018, March 31, 2018 and December 31, 2017, respectively, based on the closing price of Asterias common stock on the NYSE American of $1.35 per share, $1.45 per share and $2.25 per share, respectively, on those dates or the last trading day of the quarter. Accordingly, we recorded an unrealized loss of $2.2 million and $19.6 million, respectively, for the three and six months ended June 30, 2018.

We expect our other income and expenses, net, to continue to fluctuate each reporting period based on the changes in the market price of our OncoCyte shares, which could significantly impact our net income or loss reported in our condensed consolidated statements of operations for each period.

40

Marketable equity securities - We account for the shares we hold in foreign equity securities as marketable equity securities, carried at fair market value on our consolidated balance sheets. Beginning on January 1, 2018, in accordance with our adoption of ASU 2016-01, all gains and losses we generate each period due to changes in fair market value, including changes in foreign currency exchange rates, from these securities are included in other income and expenses, net, in our condensed consolidated statements of operations. For the three and six months ended June 30, 2019, we recorded an unrealized loss of $0.6 million and a gain of $1.3 million, respectively, due to changes in fair market value of the marketable equity securities from March 31, 2019 to June 30, 2019 and December 31, 2018 to June 30, 2019.

Gain on sale of equity method investment in Ascendance - On March 23, 2018, Ascendance, AgeX’s equity method investee and BioTime’s former equity method investee, was acquired by a third party in a merger. AgeX received $3.2 million in cash for its Ascendance common stock from which we recognized a gain on sale for the same amount during the three months ended March 31, 2018.

Other income (expense), net, interest income, net - Other income and expenses, net, in 2019 and 2018 consist primarily of net foreign currency transaction gains and losses recognized by Cell Cure and ESI, changes in the fair value of the Cell Cure Warrants, dividend income and interest income, net. Foreign currency transaction gains and losses for the periods presented are principally related to the remeasurement of the US dollar denominated notes payable by Cell Cure to BioTime.

Income Taxes

For items that we cannot reliably estimate on an annual basis (principally unrealized gains or losses generated by changes in the market prices of the OncoCyte and AgeX shares of common stock we hold, and prior to March 8, 2019, Asterias shares we held), we use the actual year to date effective tax rate rather than an estimated annual effective tax rate to determine the tax effect of each item, including the use of all available net operating losses and other credits or deferred tax assets.

The market value of the shares of OncoCyte common stock we hold creates a deferred tax liability based on the closing prices of the shares, less our tax basis in the shares. The deferred tax liability generated by the OncoCyte shares that we hold as of June 30, 2019, is a source of future taxable income to us, as prescribed by ASC 740-10-30-17, that will more likely than not result in the realization of our deferred tax assets to the extent of the deferred tax liability. This deferred tax liability is determined based on the closing prices of the OncoCyte shares as of June 30, 2019. Due to the inherent unpredictability of future prices of those shares, we cannot reliably estimate or project those deferred tax liabilities on an annual basis. Therefore, the deferred tax liability pertaining to OncoCyte shares, determined based on the actual closing prices on the last stock market trading day of the applicable accounting period, and the related impacts to the valuation allowance and deferred tax asset changes, are recorded in the accounting period in which they occur.

On March 23, 2018, Ascendance was acquired by a third party in a merger though which AgeX received approximately $3.2 million in cash for its shares of Ascendance common stock. For financial reporting purposes, AgeX recognized a $3.2 million gain as a sale of its equity method investment in Ascendance. The sale was a taxable transaction to AgeX generating a taxable gain of approximately $2.2 million, for which we had sufficient losses from operations to offset the entire gain resulting in no income taxes due.

The Juvenescence Transaction was a taxable event for us that resulted in a gross taxable gain of approximately $29.4 million, which was fully offset with available current year net operating losses (NOL) and NOL carryforwards, resulting in no net income taxes due. Although the AgeX Deconsolidation on August 30, 2018 was not a taxable transaction to us and did not result in a current tax payment obligation, the financial reporting gain on the AgeX Deconsolidation generated a deferred tax liability, primarily representing the difference between book and tax basis of AgeX common stock on the AgeX Deconsolidation date. We expect this deferred tax liability to be fully offset by a corresponding release of our valuation allowance on deferred tax assets, resulting in no income tax provision or benefit from the AgeX Deconsolidation. The deferred tax liabilities on our investments in OncoCyte and Asterias, combined with the estimated deferred tax liability generated by the fair value of our retained noncontrolling investment in AgeX, are considered to be sources of taxable income that will more likely than not result in the realization of its deferred tax assets to the extent of those deferred tax liabilities, thereby reducing the need for a valuation allowance.

The distribution of AgeX shares of common stock to our shareholders on November 28, 2018 was a taxable event for us that resulted in a gross taxable gain of approximately $26.4 million, which we fully offset with available NOL Carryforwards, resulting in no income taxes due.

In connection with the Asterias Merger, a deferred tax liability of $13.0 million was recorded as part of acquisition accounting. This liability is related to fair value adjustments for the assets and liabilities acquired in the Asterias Merger, principally consisting of IPR&D. This estimate of deferred taxes was determined based on the excess of the estimated fair values of the acquired assets and liabilities over the tax basis of the assets and liabilities acquired. The statutory tax rate was applied, as appropriate, to the adjustment based on the jurisdiction in which the adjustment is expected to occur. This estimate of deferred income tax liabilities is preliminary and is subject to change based upon our final determination of the fair value of assets acquired and liabilities assumed.

41

A valuation allowance is provided when it is more likely than not that some portion of the deferred tax assets will not be realized. For federal and state income tax purposes, as a result of the deconsolidation of AgeX, Asterias and OncoCyte and the deferred tax liabilities generated from the market values of AgeX, Asterias and OncoCyte shares from the respective deconsolidation dates, including the changes to those deferred tax liabilities due to changes in the Asterias and OncoCyte stock prices, our deferred tax assets exceeded our deferred tax liabilities as of December 31, 2018. As a result, we established a full valuation allowance as of December 31, 2018 due to the uncertainty of realizing future tax benefits from our net operating loss carryforwards and other deferred tax assets.

Because the IPR&D (prior to completion or abandonment of the R&D) is considered an indefinite-lived asset for accounting purposes, the fair value of the IPR&D on the acquisition date creates a deferred income tax liability in accordance with ASC 740. This DTL is computed using the fair value of the IPR&D assets on the acquisition date multiplied by our respective federal and state income tax rates. While this DTL would reverse on impairment or sale or commencement of amortization of the related intangible assets, those events are not anticipated under ASC 740 for purposes of predicting reversal of a temporary difference to support the realization of deferred tax assets, except for certain deferred tax assets and credit carryforwards that are also indefinite in nature as of the Asterias Merger date, which may be considered for reversal.

For the three and six months ended June 30, 2019, we reversed a portion of our valuation allowance. The partial reversal of the historical valuation allowance is related to our deferred tax assets and credit carryforwards and is due to the acquired taxable temporary differences, primarily consisting of the acquired IPR&D discussed in Note 13 to condensed consolidated financial statements included elsewhere in this Report. ASC 740 allows for deferred tax assets and credit carryforwards that are both available and indefinite in nature to be used against similar deferred tax liabilities as a source of income to support the realization of those deferred tax assets and credit carryforwards. Any benefit recognized from such a reversal of the valuation allowance is recorded outside of the acquisition accounting. Accordingly, the $1.2 million and $5.6 million valuation allowance release and the corresponding tax benefit was primarily related to state research and development credits, including current year federal net operating losses generated for the three and six months ended June 30, 2019, both of which are available and indefinite in nature.

We did not record any provision or benefit for income taxes for the six months ended June 30, 2018 as we have a full valuation allowance for the period presented.

We expect that deferred income tax expense or benefit we record each reporting period, if any, will vary depending on the change in the closing stock prices of OncoCyte and AgeX shares, from period to period and the related changes in those deferred tax liabilities and our deferred tax assets and other credits, including changes in the valuation allowance, for each period. We also expect that if we continue to generate deferred tax assets and other credits that are indefinite in nature, we may be able to release our valuation allowance with a corresponding tax benefit to the extent of our deferred tax liability which is also indefinite in nature, principally related to our acquired IPR&D.

Liquidity and Capital Resources

At June 30, 2019, we had $16.7 million of cash, cash equivalents and marketable equity securities on hand. Additionally, we raised $4.2 million in a sale of a portion of our OncoCyte holdings and $1.2 million in sales of a portion of our Hadasit Bio-Holdings Ltd holdings in July 2019. We also hold 12.4 million OncoCyte shares (which had a market value of $21.7 million as of August 6, 2019 based on the closing price of OncoCyte common stock on that date) that we may use for liquidity, as necessary, and as market conditions allow. The market value may not represent the amount that could be realized in a sale of OncoCyte shares due to various market and regulatory factors, including trading volume or market depth factors and volume and manner of sale restrictions under Federal securities laws, prevailing market conditions and prices at the time of any sale, and subsequent sales of securities by the subsidiaries.

Since inception, we have incurred significant operating losses and have funded our operations primarily through the issuance of equity securities, the sale of common stock of our former subsidiaries, AgeX and OncoCyte, payments from research grants, royalties from product sales and sales of research products and services. At June 30, 2019, we had an accumulated deficit of $252.4 million, working capital of $12.6 million and shareholders’ equity of $131.8 million. We evaluated the projected cash flows for BioTime and our subsidiaries, and we believe that our $16.7 million in cash, cash equivalents and marketable equity securities at June 30, 2019, plus the $4.2 million raised in July 2019, and the value of our remaining investment in OncoCyte, provide sufficient cash, cash equivalents, and liquidity to carry out our current planned operations through at least twelve months from the issuance date of our condensed consolidated interim financial statements included elsewhere in this Report. If we need near term working capital or liquidity to supplement our cash and cash equivalents for our operations, we may sell some, or all, of our investments, as necessary.

On March 8, 2019, the Asterias Merger closed and Asterias became our wholly owned subsidiary. We began consolidating Asterias’ operations and results with our operations and results beginning on March 8, 2019. As we integrate Asterias’ operations into our own, we have made extensive reductions in headcount and reduced non-clinical related spend, in each case, as compared to Asterias’ operations before the merger.

We expect to spend $14 million to $15 million in the second half of 2019. We anticipate that cash spend in 2020 will range from $24 million to $28 million, a reduction from 2019 spending levels of $32 million to $34 million due to corporate simplification and cost savings initiatives implemented in 2019, and a significant reduction from 2018 spending levels of $43 million for BioTime and Asterias combined.

42

Our projected cash flows are subject to various risks and uncertainties, and the unavailability or inadequacy of financing to meet future capital needs could force us to modify, curtail, delay, or suspend some or all aspects of our current planned operations. Our determination as to when we will seek new financing and the amount of financing that we will need will be based on our evaluation of the progress we make in our research and development programs, any changes to the scope and focus of those programs, any changes in grant funding for certain of those programs, and projection of future costs, revenues, and rates of expenditure. We may be required to delay, postpone, or cancel our clinical trials or limit the number of clinical trial sites, unless we are able to obtain adequate financing. In addition, we have incurred and expect to continue incurring significant costs in connection with the acquisition of Asterias and with integrating its operations. We may incur additional costs to maintain employee morale and to retain key employees. We cannot assure that adequate financing will be available on favorable terms, if at all. Sales of additional equity securities by us or our subsidiaries and affiliates could result in the dilution of the interests of our current shareholders.

Cash flows used in operating activities

Net cash used in operating activities of $19.0 million for the six months ended June 30, 2019 primarily reflects the loss from operations of $23.6 million, offset primarily by non-cash expenses of $2.2 million for stock-based compensation and $1.5 million of depreciation and amortization. The unrealized gains on equity method investments and marketable securities and deferred tax benefit are non-cash items that had no effect on cash flows.

Net cash used in operating activities of $17.7 million for the six months ended June 30, 2018 primarily reflects the loss from operations of $21.2 million plus the changes in assets and liabilities of $1.4 million. These items were offset primarily by non-cash expenses of $2.1 million for stock-based compensation and $1.7 million of depreciation and amortization. The unrealized gains on equity method investments and marketable securities are non-cash items that had no effect on cash flows.

Cash flows provided by investing activities

Cash provided by investing activities of $2.8 million for the six months ended June 30, 2019 was associated primarily with the receipt of $3.1 million of cash that Asterias had on the closing date of the Asterias Merger, offset by $0.4 million in purchases of equipment and other assets. Cash provided by investing activities of $2.2 million for the six months ended June 30, 2018 was associated primarily with proceeds of $3.2 million related to the sale of the equity method investment in Ascendance, offset by $0.8 million for the purchase of in-process research and development and $0.2 million in purchases of equipment and other assets.

Cash flows provided by financing activities

Cash provided by financing activities of $0.5 million for the six months ended June 30, 2019 was associated primarily with $0.7 million in landlord reimbursements for tenant improvements, offset by $0.1 million in common shares received and retired for employee taxes paid. Cash provided by financing activities of $5.5 million for the six months ended June 30, 2018 was associated primarily with $5.0 million in proceeds from the sale of subsidiary stock and $0.7 million in proceeds from the sale of subsidiary warrants, offset by $0.2 million for repayment of lease liability and capital lease obligation.

Off-Balance Sheet Arrangements

As of June 30, 2019 and December 31, 2018, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Under SEC rules and regulations, as a smaller reporting company, we are not required to provide the information required by this item.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

It is management’s responsibility to establish and maintain adequate internal control over all financial reporting pursuant to Rule 13a-15 under the Securities Exchange Act of 1934 (“Exchange Act”). Our management, including our principal executive officer and our principal financial officer, have reviewed and evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Report. Following this review and evaluation, management collectively determined that our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms; and (ii) is accumulated and communicated to management, including our chief executive officer and our chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the period covered by this Report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we are subject to legal proceedings and claims in the ordinary course of business. While management presently believes that the ultimate outcome of these proceedings, individually and in the aggregate, will not materially harm our financial position, cash flows, or overall trends in results of operations, legal proceedings are subject to inherent uncertainties, and unfavorable rulings or outcomes could occur that have individually or in aggregate, a material adverse effect on our business, financial condition or operating results. Except as described below, we are not currently subject to any pending material litigation, other than ordinary routine litigation incidental to our business, as described above.

On February 19, 2019, a putative class action lawsuit challenging the Asterias merger was filed on behalf of Asterias shareholders in the Superior Court of the State of California, County of Alameda. On March 1, 2019, Asterias made certain amendments and supplements to its public disclosures regarding the Asterias Merger (the “Supplemental Disclosures”). On May 3, 2019, an amended class action complaint (the “Amended Complaint”) was filed. The Amended Complaint brings claims under Delaware law for breaches of fiduciary duty against the Asterias board of directors and claims for aiding and abetting against BioTime, Neal Bradsher, Broadwood Capital, Inc. and Broadwood Partners, L.P. The Amended Complaint alleges, among other things, that the process leading up to the Asterias Merger was conflicted and inadequate, and that the proxy statement filed by Asterias with the Securities and Exchange Commission omitted certain material information, which allegedly rendered the information disclosed materially misleading. The Amended Complaint seeks, among other things, that a class be certified, the recovery of monetary damages, and attorneys’ fees and costs.

On June 3, 2019, defendants filed demurrers to the Amended Complaint. Plaintiffs’ counsel subsequently indicated that, after reviewing the demurrers and analyzing certain documents produced by defendants, Plaintiffs wished to voluntarily dismiss the action with prejudice as to themselves, and without prejudice as to the unnamed putative class members. Plaintiffs’ counsel also indicated that, independent of their decision to voluntarily dismiss the action, Plaintiffs believe they have a claim for attorneys’ fees and expenses in connection with the purported benefit conferred on Asterias stockholders by the Supplemental Disclosures (the “Fee Claim”). On July 26, 2019, the parties entered into a stipulation to stay the briefing schedule on the demurrers and to take the hearing on the demurrers off calendar so that the parties could discuss the Fee Claim (the “Stipulation”). On July 29, 2019, the Court entered the Stipulation as an order, took the demurrer hearing off calendar, and set a case management conference for September 17, 2019. Thereafter, the parties began negotiating the Fee Claim and, on August 5, 2019, agreed in principle to resolve the Fee Claim for $200,000. The parties intend to submit a stipulation to the Court seeking dismissal of the action with prejudice as to the named Plaintiffs and without prejudice as to the unnamed putative class members, and seeking approval of the negotiated Fee Claim. We continue to believe that the claims and allegations in the action lack merit, but believe that it is in our shareholders’ best interest for the action to be dismissed and to resolve the Fee Claim in a timely manner without additional costly litigation expenses.

Item 1A. Risk Factors

Our business, financial condition, results of operations and future growth prospects are subject to various risks, including those described in Item 1A “Risk Factors” of our Annual Report on Form 10-K, filed with the Securities and Exchange Commission on March 14, 2019 (the “2018 Form 10-K”), which we encourage you to review. There have been no material changes from the risk factors disclosed in the 2018 Form 10-K.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Business Overview

1. Organization and Business Overview

BioTime is a clinical-stage biotechnology company developing novel cell therapies for unmet medical needs. Our current focus is on therapies for degenerative retinal diseases, neurological conditions associated with demyelination, and aiding the body in detecting and combating cancer. BioTime’s programs are based on its proprietary cell-based therapy platform and associated development and manufacturing capabilities. With this platform BioTime develops and manufactures specialized, terminally-differentiated human cells from its pluripotent and progenitor cell starting materials. These differentiated cells are developed either to replace or support cells that are dysfunctional or absent due to degenerative disease or traumatic injury, or administered as a means of helping the body mount an effective immune response to cancer.

BioTime has three cell therapy programs in clinical development:

● OpRegen^®, a retinal pigment epithelium cell replacement therapy currently in a Phase I/IIa multicenter clinical trial for the treatment of advanced dry-age-related macular degeneration (“dry-AMD”) with geographic atrophy. There currently are no therapies approved by the U.S. Food and Drug Administration (“FDA”) for dry-AMD, which accounts for approximately 85-90% of all AMD cases and is a leading cause of blindness in people over the age of 65.

● OPC1, an oligodendrocyte progenitor cell therapy currently in a Phase I/IIa multicenter clinical trial for acute spinal cord injuries. This clinical trial has been partially funded by the California Institute for Regenerative Medicine.

● VAC2, an allogeneic (non-patient-specific or “off-the-shelf”) cancer immunotherapy of antigen-presenting dendritic cells currently in a Phase I clinical trial in non-small cell lung cancer. This clinical trial is being funded and conducted by Cancer Research UK, the world’s largest independent cancer research charity.

BioTime also has cell/drug delivery programs that are based upon its proprietary HyStem^® cell and drug delivery matrix technology. HyStem was designed to support the formulation, transfer, retention, and engraftment of cellular therapies.

BioTime is also enabling early-stage programs in other new technologies through its own research programs.

Asterias Merger

On November 7, 2018, BioTime, Asterias and Patrick Merger Sub, Inc., a wholly owned subsidiary of BioTime (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) whereby BioTime agreed to acquire all of the outstanding common stock of Asterias in a stock-for-stock transaction (the “Asterias Merger”).

On March 7, 2019, the shareholders of each of BioTime and Asterias approved the Merger Agreement. Prior to the consummation of the Merger Agreement, BioTime owned approximately 38% of Asterias’ issued and outstanding common stock and accounted for Asterias as an equity method investment.

On March 8, 2019, the Asterias merger closed with Asterias surviving as a wholly owned subsidiary of BioTime. The former stockholders of Asterias (other than BioTime) received 0.71 shares of BioTime common stock for every share of Asterias common stock they owned. BioTime issued 24,695,898 shares of common stock, including 58,085 shares issued in respect of restricted stock units issued by Asterias that immediately vested in connection with the closing of the Asterias Merger. The aggregate dollar value of such shares, based on the closing price of BioTime common stock on March 8, 2019, was $32.4 million. BioTime also assumed warrants to purchase shares of Asterias common stock.

The Asterias Merger has been accounted for using the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, which requires, among other things, that the assets and liabilities assumed be recognized at their fair values as of the acquisition date.

See Note 3 for a full discussion of the Asterias Merger.

Investment in OncoCyte

BioTime has significant equity holdings in OncoCyte Corporation (“OncoCyte”), a publicly traded company, which BioTime founded and, in the past, was a majority-owned consolidated subsidiary. OncoCyte (NYSE American: OCX) is developing confirmatory diagnostic tests for lung cancer utilizing novel liquid biopsy technology. As of June 30, 2019, BioTime owned 14.7 million shares of OncoCyte common stock, or 28% of its outstanding shares (see Note 16).

Accounting Policies [Abstract]

Basis of Presentation, Liquidity and Summary of Significant Accounting Policies

2. Basis of Presentation, Liquidity and Summary of Significant Accounting Policies

The unaudited condensed consolidated interim financial statements presented herein, and discussed below, have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. In accordance with those rules and regulations certain information and footnote disclosures normally included in comprehensive consolidated financial statements have been condensed or omitted. The condensed consolidated balance sheet as of December 31, 2018 was derived from the audited consolidated financial statements at that date, but does not include all the information and footnotes required by GAAP. These condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in BioTime’s Annual Report on Form 10-K for the year ended December 31, 2018.

The accompanying condensed consolidated interim financial statements, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of BioTime’s financial condition and results of operations. The condensed consolidated results of operations are not necessarily indicative of the results to be expected for any other interim period or for the entire year.

Principles of consolidation

BioTime’s condensed consolidated interim financial statements include the accounts of its subsidiaries. The following table reflects BioTime’s ownership, directly or through one or more subsidiaries, of the outstanding shares of its operating subsidiaries as of June 30, 2019.

Subsidiary	Field of Business	BioTime Ownership		Country
Asterias BioTherapeutics, Inc.	Cell therapy clinical development programs in spinal cord injury and oncology		100%	USA
Cell Cure Neurosciences Ltd. (“Cell Cure”)	Products to treat age-related macular degeneration		99% (1)	Israel
ES Cell International Pte. Ltd. (“ESI”)	Stem cell products for research, including clinical grade cell lines produced under cGMP		100%	Singapore
OrthoCyte Corporation (“OrthoCyte”)	Developing bone grafting products for orthopedic diseases and injuries		99.8%	USA

⁽¹⁾ Includes shares owned by BioTime and ESI.

For the three and six months ended June 30, 2018, BioTime’s unaudited consolidated results include AgeX’s consolidated results for the full period presented. As a result of the AgeX Deconsolidation, beginning on August 30, 2018 (a) AgeX’s consolidated financial statements and consolidated results are no longer a part of BioTime’s condensed consolidated interim financial statements and results, and (b) the fair value of AgeX common stock held by BioTime is now reflected on BioTime’s condensed consolidated balance sheet and the changes in the fair value of those shares during the applicable reporting period are reflected as gains or losses in BioTime’s condensed consolidated statements of operations included in other income and expenses, net.

All material intercompany accounts and transactions have been eliminated in consolidation. As of June 30, 2019, BioTime consolidated its direct and indirect wholly owned or majority-owned subsidiaries because BioTime has the ability to control their operating and financial decisions and policies through its ownership, and the noncontrolling interest is reflected as a separate element of shareholders’ equity on BioTime’s consolidated balance sheets.

Liquidity

Since inception, BioTime has incurred significant operating losses and has funded its operations primarily through the issuance of equity securities, sale of common stock of AgeX, a former subsidiary, receipt of research grants, royalties from product sales, license revenues and sales of research products. Additionally, BioTime raised $4.2 million in a sale of a portion of its OncoCyte holdings and $1.2 million in sales of a portion of its Hadasit Bio-Holdings Ltd. (“Hadasit”) holdings in July 2019 (see Note 16). At June 30, 2019, BioTime had an accumulated deficit of approximately $252.4 million, working capital of $12.6 million and shareholders’ equity of $131.8 million. BioTime has evaluated its projected cash flows and believes that its $16.7 million of cash, cash equivalents and marketable equity securities at June 30, 2019, plus the $4.2 million in net proceeds from the sale of OncoCyte shares of common stock in July 2019 and the value of its remaining equity investment in OncoCyte (which was approximately $21.7 million based on the closing price of OncoCyte common stock of $1.75 per share on August 6, 2019), provide sufficient cash, cash equivalents, and liquidity to carry out BioTime’s current planned operations through at least twelve months from the issuance date of the consolidated financial statements included herein. If BioTime needs near term working capital or liquidity to supplement its cash and cash equivalents for its operations, BioTime may sell some, or all, of its investments, as necessary.

The AgeX Distribution was completed on November 28, 2018 when AgeX became a publicly traded company (see Note 6). BioTime continues to hold a minority interest in AgeX that may be a source of additional liquidity to BioTime as a marketable equity security.

If the promissory note issued by Juvenescence in favor of BioTime discussed in Note 5 is converted into equity securities of Juvenescence prior to its maturity date, the Juvenescence equity securities may be marketable securities that BioTime may use to supplement its liquidity, as needed. If such promissory note is not converted, it is payable in cash, plus accrued interest, at maturity on August 30, 2020.

On March 8, 2019, with the consummation of the Asterias Merger, Asterias became BioTime’s wholly owned subsidiary. BioTime began consolidating Asterias’ operations and results with its operations and results beginning on March 8, 2019 (see Note 3). As BioTime integrates Asterias’ operations into its own, BioTime expects to make extensive reductions in headcount and to reduce non-clinical related spend, in each case, as compared to Asterias’ operations before the Asterias Merger.

BioTime’s projected cash flows are subject to various risks and uncertainties, and the unavailability or inadequacy of financing to meet future capital needs could force BioTime to modify, curtail, delay, or suspend some or all aspects of its planned operations. BioTime’s determination as to when it will seek new financing and the amount of financing that it will need will be based on BioTime’s evaluation of the progress it makes in its research and development programs, any changes to the scope and focus of those programs, any changes in grant funding for certain of those programs, and projection of future costs, revenues, and rates of expenditure. BioTime may be required to delay, postpone, or cancel clinical trials or limit the number of clinical trial sites, unless it is able to obtain adequate financing. In addition, BioTime has incurred and expects to continue incurring significant costs in connection with the acquisition of Asterias and with integrating its operations. BioTime may incur additional costs to maintain employee morale and to retain key employees. BioTime cannot assure that adequate financing will be available on favorable terms, if at all. Sales of additional equity securities by BioTime or its subsidiaries and affiliates could result in the dilution of the interests of current shareholders.

Business Combinations

BioTime accounts for business combinations, such as the Asterias Merger completed in March 2019, in accordance with ASC Topic 805, which requires the purchase price to be measured at fair value. When the purchase consideration consists entirely of shares of BioTime’s common stock, BioTime calculates the purchase price by determining the fair value, as of the acquisition date, of shares issued in connection with the closing of the acquisition. BioTime recognizes estimated fair values of the tangible assets and intangible assets acquired, including in-process research and development (“IPR&D”), and liabilities assumed as of the acquisition date, and records as goodwill any amount of the fair value of the tangible and intangible assets acquired and liabilities assumed in excess of the purchase price.

Equity method investments 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 a 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 in other income and expenses, net.

As further discussed in Note 4, BioTime has elected to account for its OncoCyte shares at fair value using the equity method of accounting because beginning on February 17, 2017, the respective date on which BioTime deconsolidated OncoCyte, BioTime has not had control of OncoCyte, as defined by GAAP, but continues to exercise significant influence over this company. Under the fair value method, BioTime’s value in shares of common stock it holds in OncoCyte is marked to market at each balance sheet date using the closing price of OncoCyte common stock on the NYSE American multiplied by the number of shares of OncoCyte held by BioTime, with changes in the fair value of the OncoCyte shares included in other income and expenses, net, in the consolidated statements of operations. The OncoCyte shares are considered level 1 assets as defined by ASC 820, Fair Value Measurements and Disclosures.

Prior to the Asterias Merger completed on March 8, 2019 discussed in Note 3, BioTime accounted for its Asterias shares held at fair value, using the equity method of accounting.

Revenue Recognition

During the first quarter of 2018, BioTime adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) ASU 2014-09, Revenues from Contracts with Customers (Topic 606), which created a single, principle-based revenue recognition model that supersedes and replaces nearly all existing U.S. GAAP revenue recognition guidance. BioTime adopted ASU 2014-09 using the modified retrospective transition method applied to those contracts which were not completed as of the adoption date. Results for reporting periods beginning on January 1, 2018 and thereafter are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with BioTime’s historical revenue recognition accounting under Topic 605.

BioTime recognizes revenue in a manner that depicts the transfer of control of a product or a service to a customer and reflects the amount of the consideration it is entitled to receive in exchange for such product or service. In doing so, BioTime follows a five-step approach: (i) identify the contract with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations, and (v) recognize revenue when (or as) the customer obtains control of the product or service. BioTime considers the terms of a contract and all relevant facts and circumstances when applying the revenue recognition standard. BioTime applies the revenue recognition standard, including the use of any practical expedients, consistently to contracts with similar characteristics and in similar circumstances.

BioTime’s largest source of revenue is currently related to government grants. In applying the provisions of ASU 2014-09, BioTime has determined that government grants are out of the scope of ASU 2014-09 because the government entities do not meet the definition of a “customer”, as defined by ASU 2014-09, as there is not considered to be a transfer of control of good or services to the government entities funding the grant. BioTime has, and will continue to, account for grants received to perform research and development services in accordance with ASC 730-20, Research and Development Arrangements, which requires an assessment, at the inception of the grant, of whether the grant is a liability or a contract to perform research and development services for others. If BioTime or a subsidiary receiving the grant is obligated to repay the grant funds to the grantor regardless of the outcome of the research and development activities, then BioTime is required to estimate and recognize that liability. Alternatively, if BioTime or a subsidiary receiving the grant is not required to repay, or if it is required to repay the grant funds only if the research and development activities are successful, then the grant agreement is accounted for as a contract to perform research and development services for others, in which case, grant revenue is recognized when the related research and development expenses are incurred (see Note 15).

Deferred grant revenues represent grant funds received from the governmental funding agencies for which the allowable expenses have not yet been incurred as of the balance sheet date reported. As of June 30, 2019, deferred grant revenue was immaterial.

Basic and diluted net income (loss) per share attributable to common shareholders

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 or restricted stock units, subject to repurchase by BioTime, if any, during the period. 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, convertible preferred stock, if any, using the if-converted method, and treasury stock held by subsidiaries, if any.

For the three months ended June 30, 2019, and for the three and six months ended June 30, 2018, BioTime reported a net loss attributable to common shareholders, and therefore, all potentially dilutive common stock was considered antidilutive for those periods. For the six months ended June 30, 2019, BioTime reported net income attributable to common shareholders, and therefore, performed an analysis of common share equivalents to determine their impact on diluted net income, and determined that none of the common share equivalents were dilutive.

The following weighted average 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):

	Three Months Ended June 30, (unaudited)				Six Months Ended June 30, (unaudited)
	2019		2018		2019		2018
Stock options		15,374		8,990		15,103		8,990
Warrants (1)		-		8,795		-		8,795
BioTime Warrants (2) (Note 3)		1,296		-		917		-
Restricted stock units		271		535		275		535

(1)	The warrants expired on October 1, 2018.
(2)	Although the BioTime Warrants are classified as liabilities, these warrants are considered for dilutive earnings per share calculations in accordance with ASC 260, Earnings Per Share, and determined to be anti-dilutive for the period presented.

Lease accounting and impact of adoption of the new lease standard

On January 1, 2019, BioTime adopted ASU 2016-02, Leases (Topic 842, “ASC 842”) and its subsequent amendments affecting BioTime: (i) ASU 2018-10, Codification Improvements to Topic 842, Leases, and (ii) ASU 2018-11, Leases (Topic 842): Targeted improvements, using the modified retrospective method (see Note 15).

BioTime management determines if an arrangement is a lease at inception. Leases are classified as either financing or operating, with classification affecting the pattern of expense recognition in the consolidated statements of operations. When determining whether a lease is a finance lease or an operating lease, ASC 842 does not specifically define criteria to determine “major part of remaining economic life of the underlying asset” and “substantially all of the fair value of the underlying asset.” For lease classification determination, BioTime continues to use (i) greater to or equal to 75% to determine whether the lease term is a major part of the remaining economic life of the underlying asset and (ii) greater to or equal to 90% to determine whether the present value of the sum of lease payments is substantially the fair value of the underlying asset. Under the available practical expedients, BioTime accounts for the lease and non-lease components as a single lease component. BioTime recognizes right-of-use (“ROU”) assets and lease liabilities for leases with terms greater than twelve months in the condensed consolidated balance sheet.

ROU assets represent BioTime’s right to use an underlying asset during the lease term and lease liabilities represent BioTime’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of BioTime’s leases do not provide an implicit rate, BioTime uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. BioTime uses the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. BioTime’s lease terms may include options to extend or terminate the lease when it is reasonably certain that BioTime will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Operating leases are included as right-of-use assets in property and equipment (see Note 15), and ROU lease liabilities, current and long-term, in the condensed consolidated balance sheets. Financing leases are included in property and equipment, and in financing lease liabilities, current and long-term, in BioTime’s condensed consolidated balance sheets.

In connection with the adoption on ASC 842 on January 1, 2019, BioTime derecognized net book value of leasehold improvements and corresponding lease liabilities of $1.9 million and $2.0 million, respectively, which was the carrying value of certain operating leases as of December 31, 2018, included in property and equipment and lease liabilities, respectively, recorded pursuant to build to suit lease accounting under the previous ASC 840 lease standard. The derecognition of these amounts from the superseded ASC 840 lease standard was offset by a cumulative effect adjustment of $0.1 million as a reduction of BioTime’s accumulated deficit on January 1, 2019. These build to suit leases were primarily related to the Alameda and the Cell Cure Leases described in Note 15. ASC 842 requires build to suit leases recognized on BioTime’s consolidated balance sheets as of December 31, 2018 to be derecognized upon the adoption of the new lease standard and be recognized in accordance with the new standard on January 1, 2019.

The adoption of ASC 842 had a material impact in BioTime’s consolidated balance sheets, with the most significant impact resulting from the recognition of ROU assets and lease liabilities for operating leases with remaining terms greater than twelve months on the adoption date (see Note 15). BioTime’s accounting for financing leases (previously referred to as “capital leases”) remained substantially unchanged.

Other recently adopted accounting pronouncements

Adoption of ASU 2016-18, Statement of Cash Flows (Topic 230) - On January 1, 2018, BioTime adopted ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents and restricted cash, and that restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the condensed consolidated statements of cash flows. The adoption of ASU 2016-18 did not have a material effect on BioTime’s condensed consolidated financial statements. However, prior period restricted cash balances included in prepaid expenses and other current assets, and in deposits and other long-term assets, on the condensed consolidated balance sheets was added to the beginning-of-period and end-of-period total consolidated cash and cash equivalents in the condensed consolidated statements of cash flows to conform to the current presentation shown below.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the condensed consolidated balance sheet dates that comprise the total of the same such amounts shown in the condensed consolidated statements of cash flows for all periods presented herein and effected by the adoption of ASU 2016-18 (in thousands):

	June 30, 2019		December 31, 2018		June 30, 2018		December 31, 2017
		(unaudited)				(unaudited)
Cash and cash equivalents	$	8,210	$	23,587	$	27,207	$	36,838

Restricted cash included in deposits and other long-term assets (see Note 15)		586		466		78		847
Total cash, cash equivalents, and restricted cash as shown in the condensed consolidated statements of cash flows	$	8,796	$	24,399	$	27,631	$	37,685

Adoption of ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting - In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for non-employee share-based payment transactions. The new standard expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. ASU 2018-07 is effective for fiscal years beginning after December 15, 2018 (including interim periods within that fiscal year). BioTime adopted ASU 2018-07 on January 1, 2019. As BioTime does not have a significant number of nonemployee share-based awards, the application of the new standard did not have a material impact on its consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Adopted - The recently issued accounting pronouncements applicable to BioTime that are not yet effective should be read in conjunction with the recently issued accounting pronouncements, as applicable and disclosed in BioTime’s Annual Report on Form 10-K for the year ended December 31, 2018.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which modifies certain disclosure requirements for reporting fair value measurements. ASU 2018-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. BioTime will adopt this standard on January 1, 2020 and is currently evaluating the disclosure requirements and its effect on the consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This standard will be effective for interim and annual reporting periods beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for annual periods beginning after December 15, 2018. BioTime has not yet completed its assessment of the impact of the new standard on its consolidated financial statements.

Asterias Merger

6 Months Ended

Jun. 30, 2019

Business Combinations [Abstract]

Asterias Merger

3. Asterias Merger

On March 8, 2019, the Asterias Merger closed with Asterias surviving as a wholly owned subsidiary of BioTime. The former stockholders of Asterias (other than BioTime) received 0.71 shares of BioTime common stock (the “Merger Consideration”) for every share of Asterias common stock they owned (the “Merger Exchange Ratio”). BioTime issued 24,695,898 shares of common stock, including 58,085 shares issued in respect of restricted stock units issued by Asterias that immediately vested in connection with the closing of the Asterias Merger. The fair value of such shares, based on the closing price of BioTime common stock on March 8, 2019, was $32.4 million.

In connection with the closing of the Asterias Merger, BioTime assumed outstanding warrants to purchase shares of Asterias common stock, as further discussed below and in Note 11, and assumed sponsorship of the Asterias 2013 Equity Incentive Plan (see Note 12). All stock options to purchase shares of Asterias common stock outstanding immediately prior to the closing of the Asterias Merger were canceled at the closing for no consideration.

As of June 30, 2019, the assets and liabilities of Asterias have been included in the condensed consolidated balance sheet of BioTime. The results of operations of Asterias from March 8, 2019 through June 30, 2019 have been included in the condensed consolidated statement of operations of BioTime for the six months ended June 30, 2019.

Calculation of the purchase price

The calculation of the purchase price for the Asterias Merger and the Merger Consideration transferred on March 8, 2019 was as follows (in thousands, except for share and per share amounts):

	BioTime (38% ownership interest)			Shareholders other than BioTime (approximate 62% ownership interest)			Total
Outstanding Asterias common stock as of March 8, 2019		21,747,569			34,783,333	(1)		56,530,902	(1)
Exchange ratio		0.710			0.710			0.710
BioTime common stock issuable		15,440,774	(2)		24,695,898	(3)		40,136,672
Per share price of BioTime common stock as of March 8, 2019	$	1.31		$	1.31		$	1.31
Purchase price (in $000s)	$	20,227	(2)	$	32,353		$	52,580

(1)	Includes 81,810 shares of Asterias restricted stock unit awards that immediately vested on March 8, 2019 and converted into the right to receive shares of BioTime common stock based on the Merger Exchange Ratio, resulting in 58,085 shares of BioTime common stock issued on March 8, 2019 as part of the Merger Consideration. These restricted stock units were principally attributable to pre-combination services and included as part of the purchase price in accordance with ASC 805. See Note 12 for Asterias restricted stock units that vested on the closing of the Asterias Merger attributable to post-combination services that were recorded outside of the purchase price as an immediate charge to stock-based compensation expense.
(2)	Estimated fair value for BioTime’s previously held 38% ownership interest in Asterias common stock is part of the total purchase price of Asterias for purposes of the purchase price allocation under ASC 805 and for BioTime’s adjustment of its 38% interest to fair value at the effective date of the Asterias Merger and immediately preceding the consolidation of Asterias’ results with BioTime. No actual shares of BioTime common stock were issued to BioTime in connection with the Asterias Merger.
(3)	Net of a de minimis number of fractional shares which were paid in cash.

Estimated purchase price allocation

BioTime allocated the acquisition consideration to tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The fair value of the acquired tangible and identifiable intangible assets were determined based on inputs that are unobservable and significant to the overall fair value measurement. It is also based on estimates and assumptions made by management at the time of the acquisition. As such, this was classified as Level 3 fair value hierarchy measurements and disclosures.

The Merger Consideration allocation below is preliminary and as additional information becomes available, BioTime may further revise the preliminary acquisition consideration allocation. BioTime expects to finalize the acquisition consideration allocation by the end of 2019. Any such revisions or changes may be material.

The following table sets forth a preliminary allocation of the purchase price to Asterias’ tangible and identifiable intangible assets acquired and liabilities assumed on the closing of the Asterias Merger, with the excess recorded as goodwill (in thousands):

Assets acquired:
Cash and cash equivalents	$	3,117
Prepaid expenses and other assets, current and noncurrent		660
Machinery and equipment		369
Long-lived intangible assets - royalty contracts		650
Acquired in-process research and development (“IPR&D”)		46,540
Total assets acquired		51,336

Liabilities assumed:
Accrued liabilities and accounts payable		1,136
Liability classified warrants		867
Deferred license revenue		200
Long-term deferred income tax liability		12,965
Total liabilities assumed		15,168
Net assets acquired, excluding goodwill (a)		36,168
Fair value of BioTime common stock held by Asterias (b)		3,435
Total purchase price (c)		52,580
Estimated goodwill (c-a-b)	$	12,977

The valuation of identifiable intangible assets and their estimated useful lives are as follows (in thousands, except for useful life):

	Preliminary Estimated Asset Fair Value		Useful Life (Years)
	(in thousands, except for useful life)
In process research and development (“IPR&D”)	$	46,540		n/a
Royalty contracts		650		5
	$	47,190

The following is a discussion of the valuation methods used to determine the fair value of Asterias’ significant assets and liabilities in connection with the Asterias Merger:

Acquired In-Process Research and Development (“IPR&D”) and Deferred Income Tax Liability - The fair value of identifiable acquired in-process research and development intangible assets consisting of $31.7 million pertaining to the AST-OPC1 program that is currently in a Phase 1/2a clinical trial for spinal cord injuries (“SCI”), which has been partially funded by the California Institute for Regenerative Medicine and $14.8 million pertaining to the AST-VAC2 program, which is a non-patient-specific (“off-the-shelf”) cancer immunotherapy derived from pluripotent stem cells for which a clinical trial in non-small cell lung cancer is being funded and sponsored by Cancer Research UK. The identification of these intangible assets are based on consideration of historical experience and a market participant’s view further discussed below; collectively, the AST-OPC1 and the AST-VAC2 are referred to as the “AST-Clinical Programs”. These intangible assets are valued primarily through the use of a probability weighted discounted cash flow method under the income approach further discussed below. BioTime considered the AST-VAC1 program, an autologous product candidate, manufactured from cells that come from the patient, and due to significant risks, substantial costs and limited opportunities in its current state associated with the AST-VAC1 program, BioTime management considered this program to have de minimis value.

BioTime determined that the estimated aggregate fair value of the AST-Clinical programs was $46.5 million as of the acquisition date using a probability weighted discounted cash flow method for each respective program. This approach estimates the probability of the AST-Clinical Programs achieving successful completion of remaining clinical trials and related approvals into the valuation technique.

To calculate fair value of the AST-Clinical programs under the discounted cash flow method, BioTime used probability-weighted, projected cash flows discounted at a rate considered appropriate given the significant inherent risks associated with cell therapy development by clinical-stage companies. Cash flows were calculated based on estimated projections of revenues and expenses related to each respective program. Cash flows were assumed to extend through a seven-year market exclusivity period for the AST-OPC1 program from the date of market launch. Revenues from commercialization of the AST-Clinical Programs were based on estimated market potential for the indication of each program. The resultant cash flows were then discounted to present value using a weighted-average cost of capital for companies with profiles substantially similar to that of BioTime, which BioTime believes represents the rate that market participants would use to value the assets. BioTime compensated for the phase of development of the program by applying a probability factor to its estimation of the expected future cash flows. The projected cash flows were based on significant assumptions, including the indications in which BioTime will pursue development of the AST-Clinical programs, the time and resources needed to complete the development and regulatory approval, estimates of revenue and operating profit related to the program considering its stage of development, the life of the potential commercialized product, market penetration and competition, and risks associated with achieving commercialization, including delay or failure to obtain regulatory approvals to conduct clinical studies, failure of clinical studies, delay or failure to obtain required market clearances, and intellectual property litigation.

These IPR&D assets are indefinite-lived intangible assets until the completion or abandonment of the associated research and development (“R&D”) efforts. Once the R&D efforts are completed or abandoned, the IPR&D will either be amortized over the asset life as a finite-lived intangible asset or be impaired, respectively, in accordance with ASC 350, Intangibles - Goodwill and Other. In accordance with ASC 350, goodwill and acquired IPR&D are determined to have indefinite lives and, therefore, are not amortized. Instead, they are tested for impairment at least annually and between annual tests if BioTime becomes aware of an event or a change in circumstances that would indicate the asset may be impaired.

Because the IPR&D (prior to completion or abandonment of the R&D) is considered an indefinite-lived asset for accounting purposes, the fair value of the IPR&D on the acquisition date creates a deferred income tax liability (“DTL”) in accordance with ASC 740, Income Taxes (see Note 13). This DTL is computed using the fair value of the IPR&D assets on the acquisition date multiplied by BioTime’s federal and state income tax rates. While this DTL would reverse on impairment or sale or commencement of amortization of the related intangible assets, those events are not anticipated under ASC 740 for purposes of predicting reversal of a temporary difference to support the realization of deferred tax assets, except for certain deferred tax assets and credit carryforwards that are also indefinite in nature as of the closing of the Asterias Merger, which may be considered for reversal under ASC 740 as further discussed in Note 13.

Royalty contracts - Asterias has certain royalty revenues for “research only use” culture media for pre-clinical research applications under certain, specific patent families under contracts which preclude the customers to sell for commercial use or for clinical trials. These royalty cash flows are generated under certain specific patent families which Asterias previously acquired from Geron Corporation (“Geron”). Asterias pays Geron a royalty for all royalty revenues received from these contracts. Because these patents are a subset of the clinical programs discussed above, are expected to continue to generate revenues for Asterias and are not to be used in the AST-OPC1 or the AST-VAC2 programs, these patents are considered to be separate long-lived intangible assets under ASC 805. These intangible assets are also valued primarily through the use of the discounted cash flow method under the income approach, and will be amortized over their useful life, estimated to be 5 years. The discounted cash flow method estimated the amount of net royalty income that can be expected under the contracts in future years. The amounts were based on observed historical trends in the growth of these revenue streams, and were estimated to terminate in approximately five years, when the key patents under these contracts will begin to expire. The resulting cash flows were discounted to the valuation date based on a rate of return that recognizes a lower level of risk associated with these assets as compared to the AST-Clinical programs discussed above.

Deferred license revenue - In September 2018, Asterias and Novo Nordisk A/S (“Novo Nordisk”) entered into an option for Novo Nordisk or its designated U.S. affiliate to license, on a non-exclusive basis, certain intellectual property related to culturing pluripotent stem cells, such as hES cells, in suspension. Under the terms of the option, Asterias received a one-time upfront payment of $1.0 million, in exchange for a 24-month period option to negotiate a non-exclusive license during which time Asterias has agreed to not grant any exclusive licenses inconsistent with the Novo Nordisk option. This option is considered a performance obligation as it provides Novo Nordisk with a material right that it would not receive without entering into the contract.

For business combination purposes under ASC 805, the fair value of this performance obligation to BioTime, from a market participant perspective, is the estimated costs BioTime may incur, plus a normal profit margin for the level of effort required to perform under the contract after the acquisition date, assuming Novo Nordisk exercised its option, including, but not limited to, negotiation costs, legal fees, arbitration, if any, and other related costs. Management has estimated those costs, plus a normal profit margin, to be approximately $200,000 in the estimated purchase price allocation.

Liability classified warrants - On May 13, 2016, in connection with a common stock offering, Asterias issued warrants to purchase 2,959,559 shares of Asterias common stock (the “Asterias Warrants”) with an exercise price of $4.37 per share that expire in five years from the issuance date, or May 13, 2021. As of the closing of the Asterias Merger, there were 2,813,159 Asterias Warrants outstanding. The Asterias Warrants contain certain provisions in the event of a Fundamental Transaction, as defined in the warrant agreement governing the Asterias Warrants (“Warrant Agreement”), that Asterias or any successor entity will be required to purchase, at a holder’s option, exercisable at any time concurrently with or within thirty days after the consummation of the fundamental transaction, the Asterias Warrants for cash in an amount equal to the calculated value of the unexercised portion of such holder’s warrants, determined in accordance with the Black-Scholes option pricing model with significant inputs as specified in the Warrant Agreement. The Asterias Merger was a Fundamental Transaction for purposes of the Asterias Warrants.

The fair value of the Asterias Warrants was determined by using Black-Scholes option pricing models which take into consideration the probability of the fundamental transaction, which for purposes of the above valuation was assumed to be at 100% and net cash settlement occurring, using the contractual remaining term of the warrants. In applying these models, these inputs included key assumptions including the per share closing price of BioTime common stock on March 8, 2019, volatility computed in accordance with the provisions of the Warrant Agreement and, to a large extent, assumptions based on discussions with a majority of the holders of the Asterias Warrants since the closing of the Asterias Merger to settle the Asterias Warrants in cash or in shares of BioTime common stock. Based on such discussions, BioTime believes the fair value of the Asterias Warrants as of the closing of the Asterias Merger is not subject to change significantly, however, to the extent any Asterias Warrants that were not settled in cash or in BioTime common stock discussed below, were automatically converted to BioTime warrants 30 days after the closing of the Asterias Merger. In April 2019, Asterias Warrants representing approximately $372,000 in fair value were settled: $332,000 in fair value was settled in exchange for 251,835 shares of BioTime common stock, and $40,000 in fair value was settled in exchange for cash. The Asterias Warrants settled in exchange for shares of BioTime common stock were held by Broadwood Partners, L.P., an Asterias and BioTime shareholder. The Asterias Warrants settled in exchange for cash were held by other parties. The remaining Asterias Warrants (representing approximately $495,000 in fair value as of March 31, 2019) were converted into warrants to purchase shares of BioTime common stock using the Merger Exchange Ratio (the “BioTime Warrants”).

As of June 30, 2019, the total number of shares of BioTime common stock subject to warrants that were assumed by BioTime in connection with the Asterias Merger was 1,089,900, with similar terms and conditions retained under the BioTime Warrants as per the original Warrant Agreements. The BioTime Warrants have an exercise price of $6.15 per warrant share and expire on May 13, 2021. BioTime is accounting for the outstanding BioTime Warrants as a liability at fair value, with subsequent changes to the fair value of the BioTime Warrants at each reporting period thereafter included in the consolidated statement of operations (see Note 11).

Fair value of BioTime common stock held by Asterias - As of March 8, 2019, Asterias held 2,621,811 shares of BioTime common stock as marketable securities on its standalone financial statements. The fair value of those shares acquired by BioTime from Asterias is determined based on the $1.31 per share closing price of BioTime common stock on March 8, 2019. Although treasury shares are not considered an asset and were retired upon BioTime’s acquisition of Asterias, the fair value of those shares is a part of the purchase price allocation shown in the tables above. These BioTime shares were retired at the completion of the Asterias Merger.

Goodwill - Goodwill is calculated as the difference between the acquisition date fair value of the consideration transferred and the values assigned to the assets acquired and liabilities assumed. Goodwill is not amortized but is tested for impairment at least annually, or more frequently if circumstances indicate potential impairment.

Depending on the structure of a particular acquisition, goodwill and identifiable intangible assets may not be deductible for tax purposes. Goodwill recorded in the Asterias Merger is not expected to be deductible for tax purposes (see Note 13).

During the three and six months ended June 30, 2019, BioTime incurred $0.9 million and $4.4 million, respectively, in acquisition related costs which were recorded in general and administrative expenses in the accompanying condensed consolidated statements of operations.

Prior to the Asterias Merger being consummated in March 2019, BioTime elected to account for its 21.7 million shares of Asterias common stock at fair value using the equity method of accounting. The fair value of the Asterias shares was approximately $20.2 million as of March 8, 2019, the closing date of the Asterias Merger, based on $0.93 per share, which was calculated by multiplying (a) $1.31, the closing price of BioTime common stock on such date by (b) the Merger Exchange Ratio. The fair value of the Asterias shares was approximately $13.5 million as of December 31, 2018, based on the closing price of Asterias common stock of $0.62 per share on such date. Accordingly, BioTime recorded an unrealized gain of $6.7 million for the six months ended June 30, 2019, representing the change in fair value of Asterias common stock from December 31, 2018 to March 8, 2019. For the six months ended June 30, 2018, BioTime recorded an unrealized loss of $19.6 million on the Asterias shares due to the decrease in Asterias’ stock price from December 31, 2017 to June 30, 2018 from $2.25 per share to $1.35 per share. All share prices were determined based on the closing price of BioTime or Asterias common stock on the NYSE American on the applicable dates.

BioTime elected to account for its 14.7 million shares of OncoCyte common stock at fair value using the equity method of accounting beginning on February 17, 2017, the date of the OncoCyte Deconsolidation. The OncoCyte shares had a fair value of $36.5 million as of June 30, 2019 and a fair value of $20.3 million as of December 31, 2018, based on the closing price of OncoCyte of $2.49 per share and $1.38 per share on those respective dates.

For the three months ended June 30, 2019, BioTime recorded an unrealized loss of $21.4 million due to the decrease in OncoCyte’s stock price from $3.95 per share at March 31, 2019 to $2.49 per share at June 30, 2019. For the three months ended June 30, 2018, BioTime recorded an unrealized gain of $6.6 million due to the increase in OncoCyte’s stock price from $2.10 per share at March 31, 2018 to $2.55 per share at June 30, 2018.

For the six months ended June 30, 2019, BioTime recorded an unrealized gain of $16.3 million due to the increase in OncoCyte’s stock price from $1.38 per share at December 31, 2018 to $2.49 per share at June 30, 2019. For the six months ended June 30, 2018, BioTime recorded an unrealized loss of $30.8 million due to the decrease in OncoCyte’s stock price from $4.65 per share at December 31, 2017 to $2.55 per share at June 30, 2018.

All share prices are determined based on the closing price of OncoCyte common stock on the NYSE American on the applicable dates, or the last day of trading of the applicable quarter, if the last day of a quarter fell on a weekend.

Sale Of Significant Ownership Interest In Agex To Juvenescence Limited

Sale of Significant Ownership Interest in AgeX to Juvenescence Limited

5. Sale of Significant Ownership Interest in AgeX to Juvenescence Limited

On August 30, 2018, BioTime entered into a Stock Purchase Agreement with Juvenescence Limited and AgeX, pursuant to which BioTime sold 14.4 million shares of common stock of AgeX to Juvenescence for $3.00 per share, or an aggregate purchase price of $43.2 million (the “Purchase Price”). Juvenescence paid $10.8 million of the Purchase Price at closing, issued an unsecured convertible promissory note dated August 30, 2018 in favor of BioTime for $21.6 million (the “Promissory Note”), and paid $10.8 million on November 2, 2018. The Stock Purchase Agreement contains customary representations, warranties and indemnities from BioTime relating to the business of AgeX, including an indemnity cap of $4.3 million, which is subject to certain exceptions. The transactions contemplated by the Stock Purchase Agreement are referred to as the Juvenescence Transaction in this Report.

The Promissory Note bears interest at 7% per annum, with principal and accrued interest payable at maturity on August 30, 2020. The Promissory Note cannot be prepaid prior to maturity or conversion. On the maturity date, if a “Qualified Financing” (as defined below) has not occurred, BioTime will have the right, but not the obligation, to convert the principal balance of the Promissory Note and accrued interest then due into Series A preferred shares of Juvenescence at a conversion price of $15.60. Upon the occurrence of a Qualified Financing on or before the maturity date, the principal balance of the Promissory Note and accrued interest will automatically convert into a number of shares of the class of equity securities of Juvenescence sold in the Qualified Financing, at the price per share at which the Juvenescence securities are sold in the Qualified Financing; and, if AgeX common stock is listed on a national securities exchange in the U.S., the number of shares of the class of equity securities issuable upon conversion may be increased depending on the market price of AgeX common stock. A Qualified Financing is generally defined as an underwritten initial public offering of Juvenescence equity securities in which gross proceeds are not less than $50.0 million. The Promissory Note is not transferable, except in connection with a change of control of BioTime.

For the three and six months ended June 30, 2019, BioTime recognized $378,000 and $756,000, respectively, in interest income on the Promissory Note. As of June 30, 2019, the principal and accrued interest balance of the Promissory Note was $22.9 million.

Shareholder Agreement

BioTime and Juvenescence entered into a Shareholder Agreement, dated August 30, 2018, setting forth the governance, approval and voting rights of the parties with respect to their holdings of AgeX common stock, including rights of representation on the AgeX Board of Directors, approval rights, preemptive rights, rights of first refusal and co-sale and drag-along and tag-along rights for so long as either BioTime or Juvenescence continue to own at least 15% of the outstanding shares of AgeX common stock. Under the Shareholder Agreement, Juvenescence and BioTime each had the right to designate two persons to a six-member AgeX Board of Directors, with the remaining two individuals to be independent of Juvenescence and BioTime. Following Juvenescence’s payment of $10.8 million on November 2, 2018 under the Stock Purchase Agreement, Juvenescence had the right to designate an additional member of the AgeX Board of Directors. As of July 30, 2019, Juvenescence has not exercised such right. Immediately following the AgeX Distribution on November 28, 2018 (see Note 6), BioTime owned 1.7 million shares of AgeX common stock, representing 4.8% of AgeX’s then issued and outstanding shares of common stock. Accordingly, in accordance with the Shareholder Agreement, as of November 28, 2018, BioTime had no right to designate any member to the AgeX Board of Directors.

In connection with the Juvenescence Transaction, the termination provision of the Shared Facilities Agreement (see Note 10) entitling AgeX or BioTime to terminate the agreement upon six months advance written notice was amended. Pursuant to the amendment, following the deconsolidation of AgeX from BioTime’s consolidated financial statements on August 30, 2018 (see Notes 6 and 10), each party retains the right to terminate the Shared Facilities Agreement at any time by giving the other party six months advance written notice, but BioTime may not do so prior to September 1, 2020.

On May 7, 2019, AgeX provided written notice that it will terminate its use of BioTime’s office and laboratory facilities as of July 31, 2019. On July 3, 2019, AgeX provided written notice that the remaining shared services would terminate as of September 30, 2019.

6. Deconsolidation and Distribution of AgeX

Deconsolidation of AgeX

On August 30, 2018, BioTime sold 14.4 million shares of the common stock of AgeX to Juvenescence (see Note 5). Immediately before that sale, BioTime and Juvenescence owned 80.4% and 5.6%, respectively, of AgeX’s outstanding common stock. Immediately following that sale, BioTime and Juvenescence owned 40.2% and 45.8%, respectively, of AgeX’s outstanding common stock. As a result, on August 30, 2018, AgeX was no longer a subsidiary of BioTime and, as of that date, BioTime experienced a “loss of control” of AgeX, as defined by GAAP. Loss of control is deemed to have occurred when, among other things, a parent company owns less than a majority of the outstanding common stock of a subsidiary, lacks a controlling financial interest in the subsidiary, and is unable to unilaterally control the subsidiary through other means such as having, or being able to obtain, the power to elect a majority of the subsidiary’s Board of Directors based solely on contractual rights or ownership of shares representing a majority of the voting power of the subsidiary’s voting securities. All of these loss-of-control factors were present with respect to BioTime’s ownership interest in AgeX as of August 30, 2018. Accordingly, BioTime deconsolidated AgeX’s consolidated financial statements and consolidated results from BioTime’s unaudited condensed consolidated financial statements and consolidated results effective on August 30, 2018, in accordance with ASC, 810-10-40-4(c).

In connection with the Juvenescence Transaction discussed in Note 5 and the AgeX Deconsolidation on August 30, 2018, in accordance with ASC 810-10-40-5, BioTime recorded a gain on deconsolidation of $78.5 million, which includes a financial reporting gain on the sale of the AgeX shares of $39.2 million, during the year ended December 31, 2018, included in other income and expenses, net, in the consolidated statements of operations.

Distribution of AgeX Shares

On November 28, 2018, BioTime distributed 12.7 million shares of AgeX common stock owned by BioTime to holders of BioTime common stock, on a pro rata basis, in the ratio of one share of AgeX common stock for every 10 shares of BioTime common stock owned. The AgeX Distribution was accounted for at fair value as a dividend-in-kind in the aggregate amount of $34.4 million, which was determined by multiplying (a) the 12.7 million shares distributed to BioTime shareholders by (b) $2.71, the closing price of AgeX common stock on the NYSE American on November 29, 2018, the first trading day of AgeX common stock.

Because BioTime has an accumulated deficit in its consolidated shareholders’ equity, the entire fair value of the AgeX Distribution was charged against common stock equity included in the consolidated statements of changes in shareholders’ equity for the year ended December 31, 2018.

Immediately following the AgeX Distribution, BioTime owned 1.7 million shares of AgeX common stock, all of which it still owns, and which represents approximately 4.6% of AgeX’s outstanding common stock as of June 30, 2019 and which shares BioTime holds as marketable equity securities.

In connection with the Asterias Merger, several Asterias employees were terminated as of the Asterias Merger date. Three of these employees had employment agreements with Asterias which entitled them to change in control and separation payments in the aggregate of $2.0 million, which such conditions were met on the Asterias Merger date. Accordingly, $2.0 million was accrued and recorded in general and administrative expenses on the merger date and paid in April 2019.

Additionally, BioTime entered into a plan of termination with substantially all other previous employees of Asterias with potential separation payments in the aggregate of $0.5 million. Termination dates for these individuals ranged from May 31, 2019 to June 28, 2019. These employees were required to provide services related to the transition and be an employee of the combined company as of their date of termination in order to receive separation benefits. Since the employees were required to render future services after the merger date, BioTime recorded the aggregate liability ratably over their respective service periods from the Asterias Merger date through the above termination dates, in accordance with ASC 420, Exit or Disposal Cost Obligations. As of June 30, 2019, a total of $0.3 million was accrued for these separation payments which represents the portion of the payments earned through June 30, 2019. This amount was paid in July 2019.

In connection with the planned relocation of BioTime’s corporate headquarters to Carlsbad, California, discussed in Note 15, in June 2019, BioTime entered into a plan of termination with certain BioTime employees with potential separation payments in the aggregate of $0.5 million. Termination dates for these individuals range from August 9, 2019 to September 30, 2019. These employees must provide services related to the transition of services and activities in connection with the relocation and be an employee of BioTime as of their date of termination in order to receive separation benefits. BioTime will record the aggregate liability ratably over their respective service periods from June through the above termination dates, in accordance with ASC 420.

As of June 30, 2019, a total of $0.2 million was accrued for these BioTime employee separation payments which represents the portion of the payments earned through June 30, 2019.

Shared Facilities and Service Agreements with Affiliates

The receivables from affiliates shown on the condensed consolidated balance sheet as of December 31, 2018, primarily represent amounts owed to BioTime by OncoCyte and AgeX under separate Shared Facilities and Service Agreements (each a “Shared Facilities Agreement”), with amounts owed by OncoCyte comprising most of that amount. These outstanding amounts were paid in full in the first quarter of 2019. Under the terms of the Shared Facilities Agreements, BioTime allows OncoCyte and AgeX to use BioTime’s premises and equipment located at BioTime’s headquarters in Alameda, California for the purpose of conducting business. BioTime also provides accounting, billing, bookkeeping, payroll, treasury, payment of accounts payable, and other similar administrative services to OncoCyte and AgeX. BioTime may also provide the services of attorneys, accountants, and other professionals who may provide professional services to BioTime and its other subsidiaries. BioTime also has provided OncoCyte and AgeX with the services of laboratory and research personnel, including BioTime employees and contractors, for the performance of research and development work for OncoCyte and AgeX at the premises.

BioTime charges OncoCyte and AgeX a “Use Fee” for services provided and for use of BioTime facilities, equipment, and supplies. For each billing period, BioTime prorates and allocates to OncoCyte and AgeX costs incurred, including costs for services of BioTime employees and use of equipment, insurance, leased space, professional services, software licenses, supplies and utilities. The allocation of costs depends on key cost drivers, including actual documented use, square footage of facilities used, time spent, costs incurred by BioTime for OncoCyte and AgeX, or upon proportionate usage by BioTime, OncoCyte and AgeX, as reasonably estimated by BioTime. BioTime, at its discretion, has the right to charge OncoCyte and AgeX a 5% markup on such allocated costs. The allocated cost of BioTime employees and contractors who provide services is based upon the number of hours or estimated percentage of efforts of such personnel devoted to the performance of services.

The Use Fee is determined and invoiced to OncoCyte and AgeX on a regular basis, generally monthly or quarterly. Each invoice is payable in full within 30 days after receipt. Any invoice, or portion thereof, not paid in full when due will bear interest at the rate of 15% per annum until paid, unless the failure to make a payment is due to any inaction or delay in making a payment by BioTime. Through June 30, 2019, BioTime has not charged OncoCyte or AgeX any interest.

In addition to the Use Fee, OncoCyte and AgeX reimburse BioTime for any out of pocket costs incurred by BioTime for the purchase of office supplies, laboratory supplies, and other goods and materials and services for the account or use of OncoCyte or AgeX. BioTime is not obligated to purchase or acquire any office supplies or other goods and materials or any services for OncoCyte or AgeX, and if any such supplies, goods, materials or services are obtained, BioTime may arrange for the suppliers to invoice OncoCyte or AgeX directly.

The Shared Facilities Agreements remain in effect until a party gives the other party written notice that the Shared Facilities Agreement will terminate on December 31 of that year, or unless it is otherwise terminated under another provision of the agreement. In addition, BioTime and AgeX may each terminate their Shared Facilities Agreement prior to December 31 of the year by giving the other party written six months’ notice to terminate, but BioTime may not do so prior to September 1, 2020.

On May 7, 2019, AgeX provided written notice that it will terminate its use of BioTime’s office and laboratory facilities as of July 31, 2019. On July 3, 2019, AgeX provided written notice that the remaining shared services would terminate as of September 30, 2019. On July 30, 2019, OncoCyte provided written notice that it planned to terminate shared services effective as of September 30, 2019, except for the use of shared facilities, which remains in force.

In the aggregate, BioTime charged Use Fees to OncoCyte and AgeX as follows (in thousands):

	Three Months Ended June 30, (unaudited)				Six Months Ended June 30, (unaudited)
	2019		2018		2019		2018
Research and development	$	491	$	217	$	984	$	437
General and administrative		179		175		411		346
Total use fees	$	670	$	392	$	1,395	$	783

The Use Fees charged to OncoCyte and AgeX shown above are not reflected in revenues, but instead BioTime’s general and administrative expenses and research and development expenses are shown net of those charges in the condensed consolidated statements of operations.

BioTime accounts for receivables from affiliates, net of payables to affiliates, if any, for similar shared services and other transactions BioTime’s consolidated subsidiaries may enter into with nonconsolidated affiliates. BioTime and the affiliates record those receivables and payables on a net basis since BioTime and the affiliates intend to exercise a right of offset of the receivable and the payable and to settle the balances net by having the party that owes the other party pay the net balance owed.

Transactions with Ascendance Biotechnology, Inc.

On March 21, 2018, AgeX and Ascendance Biotechnology, Inc. (“Ascendance”), an equity method investee of AgeX and former equity method investee of BioTime, entered into an Asset Purchase Agreement (the “Asset Agreement”) in which AgeX purchased for $800,000 in cash certain assets consisting primarily of in-process research and development assets related to stem cell derived cardiomyocytes (heart muscle cells) to be developed by AgeX. The transaction was considered an asset acquisition rather than a business combination in accordance with ASC 805. Accordingly, the $800,000 purchase price was expensed on the acquisition date as acquired in-process research and development as those assets have no alternative future use. Also, on March 21, 2018, BioTime received $0.2 million from Ascendance as settlement of its accounts receivable from Ascendance.

Disposition of ownership interest in Ascendance

On March 23, 2018, Ascendance was acquired by a third party in a merger through which AgeX received approximately $3.2 million in cash for its shares of Ascendance common stock. AgeX recognized a $3.2 million gain on the sale of its equity method investment in Ascendance, which is included in other income and expenses, net, for the six months ended June 30, 2018.

Other related party transactions

In February 2018, Alfred D. Kingsley, the Chairman of BioTime’s Board of Directors and a former officer and director of AgeX, purchased AgeX stock purchase warrants entitling him to purchase 248,600 shares of AgeX common stock at an exercise price of $2.50 per share. AgeX received $124,300, or $0.50 per warrant, from Mr. Kingsley. The warrants were sold to Mr. Kingsley on the same terms as other warrants were sold by AgeX to other unaffiliated investors.

BioTime currently pays $5,050 per month for the use of approximately 900 square feet of office space in New York City, which is made available to BioTime on a month-by-month basis by one of its directors at an amount that approximates his cost (see Note 15).

In April 2019, BioTime issued 251,835 shares of BioTime common stock to Broadwood Partners, L.P., an Asterias and BioTime shareholder, in exchange for the settlement of Asterias Warrants in connection with the Asterias Merger (see Note 3).

In connection with the putative shareholder class action lawsuit filed in February 2019 challenging the Asterias Merger (see Note 15), BioTime has agreed to pay for the legal defense of Neal Bradsher, director, and Broadwood Partners, L.P., a shareholder of BioTime, and Broadwood Capital, Inc., which manages Broadwood Partners, L.P., all of which were named in the lawsuit. Through June 30, 2019, BioTime has incurred a total of $140,000 in legal expenses on behalf of the director, shareholder, and the manager of the shareholder.

At June 30, 2019, BioTime was authorized to issue 250,000,000 common shares, no par value. As of June 30, 2019, and December 31, 2018, BioTime had 149,642,861 and 127,135,774 issued and outstanding common shares, respectively.

In April 2017, BioTime entered into a Controlled Equity Offering^SM Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co., as sales agent (“Cantor Fitzgerald”), pursuant to which BioTime may offer and sell, from time to time, through Cantor Fitzgerald, shares of BioTime common stock having an aggregate offering price of up to $25,000,000. BioTime is not obligated to sell any shares under the Sales Agreement. Subject to the terms and conditions of the Sales Agreement, Cantor Fitzgerald will use commercially reasonable efforts, consistent with its normal trading and sales practices, applicable state and federal law, rules and regulations, and the rules of the NYSE American, to sell the shares from time to time based upon BioTime’s instructions, including any price, time or size limits specified by BioTime. Under the Sales Agreement, Cantor Fitzgerald may sell the shares by any method deemed to be an “at-the-market” offering as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended, or by any other method permitted by law, including in privately negotiated transactions. Cantor Fitzgerald’s obligations to sell the shares under the Sales Agreement are subject to satisfaction of certain conditions, including the continued effectiveness of BioTime’s Registration Statement on Form S-3, which became effective on May 5, 2017. As of June 30, 2019, $24.2 million remained available for sale through the Sales Agreement.

BioTime agreed to pay Cantor Fitzgerald a commission of 3.0% of the aggregate gross proceeds from each sale of shares, reimburse legal fees and disbursements and provide Cantor Fitzgerald with customary indemnification and contribution rights. The Sales Agreement may be terminated by Cantor Fitzgerald or BioTime at any time upon notice to the other party, or by Cantor Fitzgerald at any time in certain circumstances, including the occurrence of a material and adverse change in BioTime’s business or financial condition that makes it impractical or inadvisable to market the shares or to enforce contracts for the sale of the shares.

Warrants

BioTime (previously Asterias) Warrants - Liability Classified

In March 2019, in connection with the closing of the Asterias Merger, BioTime assumed outstanding Asterias Warrants. As of June 30, 2019, the total number of shares of BioTime common stock subject to warrants that were assumed by BioTime in connection with the Asterias Merger was 1,089,900 (representing approximately $289,000 in fair value as of June 30, 2019), which were converted to BioTime Warrants 30 days after the closing of the Asterias Merger, with similar terms and conditions retained under the BioTime Warrants as per the original Warrant Agreements. The BioTime Warrants have an exercise price of $6.15 per warrant share and expire on May 13, 2021. BioTime is accounting for the outstanding BioTime Warrants as a liability at fair value, with subsequent changes to the fair value of the BioTime Warrants at each reporting period thereafter included in the consolidated statement of operations (see Note 3).

For the three and six months ended months ended June 30, 2019, BioTime recorded an unrealized gain of $0.2 million due to the decline in the fair value of the BioTime Warrants from the Asterias Merger date through June 30, 2019. As of June 30, 2019, the fair value of the BioTime Warrants was $0.3 million included in long-term liabilities on the condensed consolidated balance sheets.

Cell Cure Warrants - Liability Classified

Cell Cure has two sets of issued warrants. Warrants to purchase 24,566 Cell Cure ordinary shares at an exercise price of $40.5359 were issued to Hadasit in July 2017. These warrants expire in July 2022. Warrants to purchase 13,738 Cell Cure ordinary shares at exercise prices ranging from $32.02 to $40.00 per share have been issued to consultants. These warrants expire in October 2020 and January 2024.

ASC 815 requires freestanding financial instruments, such as warrants, with exercise prices denominated in currencies other than the functional currency of the issuer to be accounted for as liabilities at fair value, with all subsequent changes in fair value after the issuance date to be recorded as gains or losses in the consolidated statements of operations.

As of June 30, 2019 and December 31, 2018, the total value of all warrants issued by Cell Cure was $0.3 million and $0.4 million, respectively. Such warrants are classified as long-term liabilities on the condensed consolidated balance sheets.

Equity Incentive Plan Awards

BioTime adopted a 2012 Equity Incentive Plan (the “2012 Plan”) for the grant of stock options, restricted stock, restricted stock units and stock appreciation rights. As of June 30, 2019, a maximum of 16,000,000 common shares were available for grant; this amount was increased to 24,000,000 common shares on July 30, 2019 when shareholder approval was obtained.

A summary of BioTime’s 2012 Plan activity and other stock option awards granted outside of the 2012 Plan related information is as follows (in thousands, except per share amounts):

	Shares Available for Grant			Number of Options Outstanding			Number of RSUs Outstanding			Weighted Average Exercise Price

At the effective time of the Asterias Merger, BioTime assumed sponsorship of the Asterias 2013 Equity Incentive Plan (the “Asterias Equity Plan”), with references to Asterias and Asterias common stock therein to be deemed references to BioTime and BioTime common stock. There were 7,309,184 shares available under the Asterias Equity Plan immediately before the closing of the Asterias Merger, which became 5,189,520 shares immediately following the Asterias Merger. The shares available under the Asterias Equity Plan will be for awards granted to those former Asterias employees who continued as BioTime employees upon consummation of the Asterias Merger. A summary of activity under the Asterias Equity Plan from the closing date of the Asterias Merger through June 30, 2019 is as follows (in thousands, except per share amounts):

Total stock-based compensation expense	$	762	$	1,103	$	2,202	$	2,087

The expense related to 84,940 shares of Asterias restricted stock unit awards that immediately vested on the closing of the Asterias Merger and converted into the right to receive shares of BioTime common stock based on the Merger Exchange Ratio, resulting in 60,304 shares of BioTime common stock issued on March 8, 2019, which were included in stock-based compensation expense for the six months ended June 30, 2019. The expense was not included as part of the purchase price of the Asterias Merger because these awards were principally attributable to post-combination services.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

13. Income Taxes

The provision for income taxes for interim periods is generally determined using an estimated annual effective tax rate as prescribed by ASC 740-270, Income Taxes, Interim Reporting. The effective tax rate may be subject to fluctuations during the year as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as valuation allowances and changes in valuation allowances against deferred tax assets, the recognition or de-recognition of tax benefits related to uncertain tax positions, if any, and changes in or the interpretation of tax laws in jurisdictions where BioTime conducts business. ASC 740-270 also states that if an entity is unable to reliably estimate some or a part of its ordinary income or loss, the income tax provision or benefit applicable to the item that cannot be estimated shall be reported in the interim period in which the item is reported.

For items that BioTime cannot reliably estimate on an annual basis (principally unrealized gains or losses generated by changes in the market prices of the OncoCyte, and AgeX shares of common stock BioTime holds, and prior to March 8, 2019, Asterias shares BioTime held), BioTime uses the actual year to date effective tax rate rather than an estimated annual effective tax rate to determine the tax effect of each item, including the use of all available net operating losses and other credits or deferred tax assets.

Although the deconsolidation of OncoCyte was not a taxable transaction to BioTime and did not create a current income tax payment obligation to BioTime, the market value of the shares of OncoCyte common stock BioTime holds creates a deferred tax liability to BioTime based on the closing prices of the shares, less BioTime’s tax basis in the shares. The deferred tax liability generated by the OncoCyte shares that BioTime holds as of June 30, 2019, is a source of future taxable income to BioTime, as prescribed by ASC 740-10-30-17, that will more likely than not result in the realization of its deferred tax assets to the extent of the deferred tax liability. This deferred tax liability is determined based on the closing prices of the OncoCyte shares as of June 30, 2019. Due to the inherent unpredictability of future prices of those shares, BioTime cannot reliably estimate or project those deferred tax liabilities on an annual basis. Therefore, the deferred tax liability pertaining to OncoCyte shares, determined based on the actual closing prices on the last stock market trading day of the applicable accounting period, and the related impacts to the valuation allowance and deferred tax asset changes, are recorded in the accounting period in which they occur.

Prior to the Asterias Merger discussed in Note 3, the Asterias shares of common stock BioTime held generated similar deferred tax liabilities to BioTime as the OncoCyte shares discussed above. As of the Asterias Merger date and due to Asterias becoming a wholly owned subsidiary of BioTime, the Asterias deferred tax liabilities were eliminated with a corresponding adjustment to BioTime’s valuation allowance, resulting in no tax provision or benefit from this adjustment.

On March 23, 2018, Ascendance was acquired by a third party in a merger through which AgeX received approximately $3.2 million in cash for its shares of Ascendance common stock. For financial reporting purposes, AgeX recognized a $3.2 million gain as a sale of its equity method investment in Ascendance. The sale was a taxable transaction to AgeX generating a taxable gain of approximately $2.2 million. BioTime had sufficient losses from operations to offset the entire gain resulting in no income taxes due.

The income tax consequences of the AgeX Deconsolidation are discussed below.

The Juvenescence Transaction discussed in Note 5 was a taxable event for BioTime that resulted in a gross taxable gain of approximately $29.4 million, which BioTime fully offset with available net operating losses (“NOL”) and NOL carryforwards, resulting in no net income taxes due. Although the AgeX Deconsolidation on August 30, 2018 was not a taxable transaction to BioTime and did not result in a current tax payment obligation, the unrealized financial reporting gain (see Note 6) on the AgeX Deconsolidation generated a deferred tax liability in accordance with ASC 740, primarily representing BioTime’s difference between book and tax basis of AgeX common stock on the AgeX Deconsolidation date. This deferred tax liability was fully offset by a corresponding release of BioTime’s valuation allowance on deferred tax assets, resulting in no income tax provision or benefit from the AgeX Deconsolidation. The deferred tax liabilities on BioTime’s investments in OncoCyte, Asterias and AgeX are considered to be sources of taxable income as prescribed by ASC 740-10-30-17 that will more likely than not result in the realization of its deferred tax assets to the extent of those deferred tax liabilities, thereby reducing the need for a valuation allowance.

The distribution of AgeX shares of common stock to BioTime shareholders (see Note 6) on November 28, 2018 was a taxable event for BioTime that resulted in a gross taxable gain of approximately $26.4 million, which was fully offset by NOL carryforwards, resulting in no income taxes due.

In connection with the Asterias Merger, a deferred tax liability of $13.0 million was recorded as part of the acquisition accounting (see Note 3). The deferred tax liability (“DTL”) is related to fair value adjustments for the assets and liabilities acquired in the Asterias Merger, principally consisting of IPR&D. This estimate of deferred taxes was determined based on the excess of the estimated fair values of the acquired assets and liabilities over the tax basis of the assets and liabilities acquired. The statutory tax rate was applied, as appropriate, to the adjustment based on the jurisdiction in which the adjustment is expected to occur. This estimate of deferred income tax liabilities is preliminary and is subject to change based upon BioTime’s final determination of the fair value of assets acquired and liabilities assumed. Because the IPR&D (prior to completion or abandonment of the R&D) is considered an indefinite-lived asset for accounting purposes, the fair value of the IPR&D on the acquisition date creates a deferred income tax liability in accordance with ASC 740. This DTL is computed using the fair value of the IPR&D assets on the acquisition date multiplied by BioTime’s respective federal and state income tax rates. While this DTL would reverse on impairment or sale or commencement of amortization of the related intangible assets, those events are not anticipated under ASC 740 for purposes of predicting reversal of a temporary difference to support the realization of deferred tax assets, except for certain deferred tax assets and credit carryforwards that are also indefinite in nature as of the Asterias Merger date, which may be considered for reversal under ASC 740 as further discussed below.

A valuation allowance is provided when it is more likely than not that some portion of the deferred tax assets will not be realized. For federal and state income tax purposes, as a result of the deconsolidation of AgeX, Asterias and OncoCyte and the deferred tax liabilities generated from the market values of AgeX, Asterias and OncoCyte shares from the respective deconsolidation dates, including the changes to those deferred tax liabilities due to changes in the AgeX, Asterias and OncoCyte stock prices, BioTime’s deferred tax assets exceeded its deferred tax liabilities as of December 31, 2018. As a result, BioTime established a full valuation allowance as of December 31, 2018 due to the uncertainty of realizing future tax benefits from its net operating loss carryforwards and other deferred tax assets.

For the three and six months ended June 30, 2019, BioTime reversed a portion of its valuation allowance. The partial reversal of the historical valuation allowance is related to BioTime’s deferred tax assets and credit carryforwards and is due to the acquired taxable temporary differences, primarily consisting of the acquired IPR&D discussed above and in Notes 3 and 8. ASC 740 allows for deferred tax assets and credit carryforwards, that are both available and indefinite in nature, to be used against similar deferred tax liabilities as a source of income to support the realization of those deferred tax assets and credit carryforwards. Any benefit recognized from such a reversal of the valuation allowance is recorded outside of the acquisition accounting. Accordingly, the $1.2 million and $5.6 million valuation allowance release and the corresponding tax benefits were primarily related to state research and development credits, including current year federal net operating losses generated for the three and six months ended June 30, 2019, respectively, both of which are available and indefinite in nature.

BioTime did not record any provision or benefit for income taxes for the three and six months ended June 30, 2018 as BioTime had a full valuation allowance for the periods presented.

Commitments and Contingencies

15. Commitments and Contingencies

Alameda Lease

In December 2015, BioTime entered into a lease for approximately 30,795 square feet of rentable space in two buildings located in an office park in Alameda, California (the “Alameda Lease”). The term of the Alameda Lease commenced effective February 1, 2016 and expires on January 31, 2023, unless BioTime exercises its option to renew the lease for an additional five years.

Base rent under the Alameda Lease beginning on February 1, 2019 is $70,521 per month and will increase by approximately 3% annually on every February 1 thereafter during the lease term.

Prior to the adoption of ASC 842 on January 1, 2019 (see Note 2), the lease payments allocated to the lease liability for leasehold improvements reimbursed by the landlord were amortized as debt service on that liability using the effective interest method over the lease term.

See Note 2 for discussion of the impact of adoption of ASC 842 on January 1, 2019, and below for the ROU assets and liabilities recorded in connection with the adoption of ASC 842 as of, and during the six months ended June 30, 2019 for the Alameda Lease.

In addition to base rent, BioTime will pay a pro rata portion of increases in certain expenses, including real property taxes, utilities (to the extent not separately metered to the leased space) and the landlord’s operating expenses, over the amounts of those expenses incurred by the landlord. As security for the performance of its obligations under the Alameda Lease, BioTime provided the landlord with a security deposit of approximately $424,000, which was reduced to $78,000 on January 24, 2019 in accordance with the terms of the lease. The security deposit amount is considered restricted cash and $78,000 is included in deposits and other long-term assets as of June 30, 2019 (see Note 2).

Carlsbad Lease

In May 2019, BioTime entered into a lease for approximately 8,841 square feet of rentable space in an office park in Carlsbad, California (the “Carlsbad Lease”). The term of the Carlsbad Lease commenced on August 1, 2019 and expires on October 31, 2022.

Base rent under the Carlsbad Lease beginning on August 1, 2019 is $17,850 per month and will increase by 3% annually on every August 1 thereafter during the lease term. Base rent for the first twenty-four months of the lease is based upon a deemed rentable area of 7,000 square feet. Base rent is abated for months two through five of the lease.

In addition to base rent, BioTime will pay a pro rata portion of increases in certain expenses, including real property taxes, utilities (to the extent not separately metered to the leased space) and the landlord’s operating expenses, over the amounts of those expenses incurred by the landlord. As security for the performance of its obligations under the Alameda Lease, BioTime provided the landlord with a security deposit of approximately $17,850.

New York Leased Office Space

BioTime currently pays $5,050 per month for the use of approximately 900 square feet of office space in New York City, which is made available to BioTime for use in conducting meetings and other business affairs, on a month-by-month basis, by one of its directors at an amount that approximates his cost. This lease was not in the scope of ASC 842 because it is a month to month lease (see Note 2).

Cell Cure Lease

Cell Cure leases 728.5 square meters (approximately 7,842 square feet) of office and laboratory space in Jerusalem, Israel under a lease that expires December 31, 2020, with two options to extend the lease for 5 years each. Base monthly rent is NIS 37,882 (approximately US $11,000 per month using the December 31, 2018 exchange rate). In addition to base rent, Cell Cure pays a pro rata share of real property taxes and certain costs related to the operation and maintenance of the building in which the leased premises are located.

On January 28, 2018, Cell Cure entered into another lease agreement for an additional 934 square meters (approximately 10,054 square feet) of office space in the same facility in Jerusalem, Israel under a lease that expires on December 31, 2025, with two options to extend the lease for 5 years each (the “January 2018 Lease”). The January 2018 Lease commenced on April 1, 2018 and included a leasehold improvement construction allowance of up to NIS 4,000,000 (approximately up to $1.1 million using the December 31, 2018 exchange rate) from the landlord. The leasehold improvements were completed in December 2018 and the entire allowance was used. Beginning on January 1, 2019, combined base rent and construction allowance payments for the January 2018 Lease are NIS 93,827 per month (approximately $26,000 per month).

Prior to the adoption of ASC 842 on January 1, 2019, Cell Cure was considered the owner of the tenant improvements under construction under ASC 840-40-55 as Cell Cure, among other things, had the primary obligation to pay for construction costs and Cell Cure retains exclusive use of the leased facilities for its office, research and cGMP manufacturing facility requirements after construction was completed (“build to suit” lease). In accordance with the ASC 840 guidance, amounts expended by Cell Cure for construction was reported as construction in progress, and the proceeds received from the landlord, if any, are reported as a lease liability. As of December 31, 2018, approximately $1.1 million under the January 2018 Lease was incurred and recorded as leasehold improvement construction in progress (see Note 7), with a corresponding amount included in long term lease liability representing the full amount utilized from the landlord’s leasehold improvement construction allowance. By March 2019, the landlord paid the complete leasehold improvement construction allowance and the property was placed in service.

See Note 2 discussion of the impact of adoption of ASC 842 on January 1, 2019, and below for the ROU assets and liabilities recorded in connection with the adoption of ASC 842 as of, and during the six months ended June 30, 2019 for the Cell Cure and January 2018 Leases above (the “Cell Cure Leases”).

Research and Option Agreement

On January 5, 2019, BioTime and Orbit Biomedical Limited (“Orbit”) entered into a Research and Option Agreement (the “Orbit Agreement”) for an exclusive partnership to assess Orbit’s vitrectomy-free subretinal injection device as a means of delivering OpRegen in BioTime’s ongoing Phase I/IIa clinical trial. The term of the Orbit Agreement is for one year unless certain research activities and related data specified in the Orbit Agreement is obtained sooner. The access fees payable by BioTime to Orbit for its technology and the injection device are $2.5 million in the aggregate, of which $1.25 million was paid in January 2019 upon execution of the Orbit Agreement and the remaining $1.25 million payment is due on the earlier of (i) six months from the Orbit Agreement date or, (ii) upon completion of certain collaborative research activities using the Orbit technology for the OpRegen Phase I/IIa clinical trial, as specified in the Orbit Agreement. In addition to the access fees, BioTime will pay Orbit for costs of consumables, training services, travel costs and other out of pocket expenses incurred by Orbit for performing services under the Orbit Agreement. BioTime has exclusive rights to the Orbit technology and its injection device for the treatment of dry-AMD during the term of the Orbit Agreement and may extend the term for an additional three months by paying Orbit a cash fee of $500,000. For the three and six months ended June 30, 2019, BioTime amortized $0.6 million and $1.25 million of the upfront payment fee included in research and development expenses. As of June 30, 2019, BioTime had not incurred the remaining $1.25 million access fee. In July 2019, BioTime completed the collaborative research activities referred to above and the second $1.25 million payment will be made in August 2019.

Litigation

BioTime will be subject to various claims and contingencies in the ordinary course of its business, including those related to litigation, business transactions, employee-related matters, and others. When BioTime is aware of a claim or potential claim, it assesses the likelihood of any loss or exposure. If it is probable that a loss will result and the amount of the loss can be reasonably estimated, BioTime will record a liability for the loss. If the loss is not probable or the amount of the loss cannot be reasonably estimated, BioTime will disclose the claim if the likelihood of a potential loss is reasonably possible and the amount involved could be material. BioTime is not aware of any claims likely to have a material adverse effect on its financial condition or results of operations.

On February 19, 2019, a putative shareholder class action lawsuit was filed (captioned Lampe v. Asterias Biotherapeutics, Inc. et al., Case No. RG19007391) in the Superior Court of the State of California, County of Alameda challenging the Asterias Merger. On March 1, 2019, Asterias made certain amendments and supplements to its public disclosures regarding the Asterias Merger (the “Supplemental Disclosures”). On May 3, 2019, an amended class action complaint (the “Amended Complaint”) was filed. The Amended Complaint names BioTime, Patrick Merger Sub, Inc., the Asterias board of directors, one member of BioTime’s board of directors, and certain stockholders of both BioTime and Asterias. The action was brought by two purported stockholders of Asterias, on behalf of a putative class of Asterias stockholders, and asserts breach of fiduciary duty and aiding and abetting claims under Delaware law. The Amended Complaint alleges, among other things, that the process leading up to the Asterias Merger was conflicted and inadequate, and that the proxy statement filed by Asterias with the Securities and Exchange Commission omitted certain material information, which allegedly rendered the information disclosed materially misleading. The Amended Complaint seeks, among other things, that a class be certified, the recovery of monetary damages, and attorneys’ fees and costs.

On June 3, 2019, defendants filed demurrers to the Amended Complaint. Plaintiffs’ counsel subsequently indicated that, after reviewing the demurrers and analyzing certain documents produced by defendants, Plaintiffs wished to voluntarily dismiss the action with prejudice as to themselves, and without prejudice as to the unnamed putative class members. Plaintiffs’ counsel also indicated that, independent of their decision to voluntarily dismiss the action, Plaintiffs believe they have a claim for attorneys’ fees and expenses in connection with the purported benefit conferred on Asterias stockholders by the Supplemental Disclosures (the “Fee Claim”). On July 26, 2019, the parties entered into a stipulation to stay the briefing schedule on the demurrers and to take the hearing on the demurrers off calendar so that the parties could discuss the Fee Claim (the “Stipulation”). On July 29, 2019, the Court entered the Stipulation as an order, took the demurrer hearing off calendar, and set a case management conference for September 17, 2019. Thereafter, the parties began negotiating the Fee Claim and, on August 5, 2019, agreed in principle to resolve the Fee Claim for $200,000. The parties intend to submit a stipulation to the Court seeking dismissal of the action with prejudice as to the named Plaintiffs and without prejudice as to the unnamed putative class members, and seeking approval of the negotiated Fee Claim. BioTime continues to believe that the claims and allegations in the action lack merit, but believes that it is in BioTime’s shareholders’ best interest for the action to be dismissed and to resolve the Fee Claim in a timely manner without additional costly litigation expenses.

Employment contracts

BioTime has entered into employment agreements with certain executive officers. Under the provisions of the agreements, BioTime may be required to incur severance obligations for matters relating to changes in control, as defined in the agreements, and involuntary terminations.

Indemnification

In the normal course of business, BioTime may provide indemnifications of varying scope under BioTime’s agreements with other companies or consultants, typically BioTime’s clinical research organizations, investigators, clinical sites, suppliers and others. Pursuant to these agreements, BioTime will generally agree to indemnify, hold harmless, and reimburse the indemnified parties for losses and expenses suffered or incurred by the indemnified parties arising from claims of third parties in connection with the use or testing of BioTime’s products and services. Indemnification provisions could also cover third party infringement claims with respect to patent rights, copyrights, or other intellectual property pertaining to BioTime products and services. The term of these indemnification agreements will generally continue in effect after the termination or expiration of the particular research, development, services, or license agreement to which they relate. The potential future payments BioTime could be required to make under these indemnification agreements will generally not be subject to any specified maximum amount. Historically, BioTime has not been subject to any claims or demands for indemnification. BioTime also maintains various liability insurance policies that provide BioTime with insurance against claims or demands for indemnification in specified circumstances. As a result, BioTime believes the fair value of these indemnification agreements is minimal. Accordingly, BioTime has not recorded any liabilities for these agreements as of June 30, 2019 and December 31, 2018.

Royalty obligations and license fees

BioTime and its subsidiaries or affiliates are parties to certain licensing agreements with research institutions, universities and other parties for the rights to use those licenses and other intellectual property in conducting research and development activities. These licensing agreements provide for the payment of royalties by BioTime or the applicable party to the agreement on future product sales, if any. In addition, in order to maintain these licenses and other rights during the product development, BioTime or the applicable party to the contract must comply with various conditions including the payment of patent related costs and annual minimum maintenance fees. Annual minimum maintenance fees are approximately $135,000 to $150,000 per year. The research and development risk for these products is significant. License fees and related expenses under these agreements were immaterial for the periods presented in the condensed consolidated interim financial statements provided herein.

Grants

Under the terms of the grant agreement between Cell Cure and Israel Innovation Authority (“IIA”) (formerly the Office of the Chief Scientist of Israel) of the Ministry of Economy and Industry, for the development of OpRegen ^® , Cell Cure will be required to pay royalties on future product sales, if any, up to the amounts received from the IIA, plus interest indexed to LIBOR. Cell Cure’s research and product development activities under the grant are subject to substantial risks and uncertainties and performed on a best efforts basis. As a result, Cell Cure is not required to make any payments under the grant agreement unless it successfully commercializes OpRegen. Accordingly, pursuant to ASC 730-20, the grant is considered a contract to perform research and development services for others and grant revenue is recognized as the related research and development expenses are incurred (see Note 2).

Israeli law pertaining to such government grants contain various conditions, including substantial penalties and restrictions on the transfer of intellectual property, or the manufacture, or both, of products developed under the grant outside of Israel, as defined by the IIA.

Accounting Policies [Abstract]

Principles of Consolidation

Principles of consolidation

BioTime’s condensed consolidated interim financial statements include the accounts of its subsidiaries. The following table reflects BioTime’s ownership, directly or through one or more subsidiaries, of the outstanding shares of its operating subsidiaries as of June 30, 2019.

Subsidiary	Field of Business	BioTime Ownership		Country
Asterias BioTherapeutics, Inc.	Cell therapy clinical development programs in spinal cord injury and oncology		100%	USA
Cell Cure Neurosciences Ltd. (“Cell Cure”)	Products to treat age-related macular degeneration		99% (1)	Israel
ES Cell International Pte. Ltd. (“ESI”)	Stem cell products for research, including clinical grade cell lines produced under cGMP		100%	Singapore
OrthoCyte Corporation (“OrthoCyte”)	Developing bone grafting products for orthopedic diseases and injuries		99.8%	USA

⁽¹⁾ Includes shares owned by BioTime and ESI.

For the three and six months ended June 30, 2018, BioTime’s unaudited consolidated results include AgeX’s consolidated results for the full period presented. As a result of the AgeX Deconsolidation, beginning on August 30, 2018 (a) AgeX’s consolidated financial statements and consolidated results are no longer a part of BioTime’s condensed consolidated interim financial statements and results, and (b) the fair value of AgeX common stock held by BioTime is now reflected on BioTime’s condensed consolidated balance sheet and the changes in the fair value of those shares during the applicable reporting period are reflected as gains or losses in BioTime’s condensed consolidated statements of operations included in other income and expenses, net.

All material intercompany accounts and transactions have been eliminated in consolidation. As of June 30, 2019, BioTime consolidated its direct and indirect wholly owned or majority-owned subsidiaries because BioTime has the ability to control their operating and financial decisions and policies through its ownership, and the noncontrolling interest is reflected as a separate element of shareholders’ equity on BioTime’s consolidated balance sheets.

Liquidity

Liquidity

Since inception, BioTime has incurred significant operating losses and has funded its operations primarily through the issuance of equity securities, sale of common stock of AgeX, a former subsidiary, receipt of research grants, royalties from product sales, license revenues and sales of research products. Additionally, BioTime raised $4.2 million in a sale of a portion of its OncoCyte holdings and $1.2 million in sales of a portion of its Hadasit Bio-Holdings Ltd. (“Hadasit”) holdings in July 2019 (see Note 16). At June 30, 2019, BioTime had an accumulated deficit of approximately $252.4 million, working capital of $12.6 million and shareholders’ equity of $131.8 million. BioTime has evaluated its projected cash flows and believes that its $16.7 million of cash, cash equivalents and marketable equity securities at June 30, 2019, plus the $4.2 million in net proceeds from the sale of OncoCyte shares of common stock in July 2019 and the value of its remaining equity investment in OncoCyte (which was approximately $21.7 million based on the closing price of OncoCyte common stock of $1.75 per share on August 6, 2019), provide sufficient cash, cash equivalents, and liquidity to carry out BioTime’s current planned operations through at least twelve months from the issuance date of the consolidated financial statements included herein. If BioTime needs near term working capital or liquidity to supplement its cash and cash equivalents for its operations, BioTime may sell some, or all, of its investments, as necessary.

The AgeX Distribution was completed on November 28, 2018 when AgeX became a publicly traded company (see Note 6). BioTime continues to hold a minority interest in AgeX that may be a source of additional liquidity to BioTime as a marketable equity security.

If the promissory note issued by Juvenescence in favor of BioTime discussed in Note 5 is converted into equity securities of Juvenescence prior to its maturity date, the Juvenescence equity securities may be marketable securities that BioTime may use to supplement its liquidity, as needed. If such promissory note is not converted, it is payable in cash, plus accrued interest, at maturity on August 30, 2020.

On March 8, 2019, with the consummation of the Asterias Merger, Asterias became BioTime’s wholly owned subsidiary. BioTime began consolidating Asterias’ operations and results with its operations and results beginning on March 8, 2019 (see Note 3). As BioTime integrates Asterias’ operations into its own, BioTime expects to make extensive reductions in headcount and to reduce non-clinical related spend, in each case, as compared to Asterias’ operations before the Asterias Merger.

BioTime’s projected cash flows are subject to various risks and uncertainties, and the unavailability or inadequacy of financing to meet future capital needs could force BioTime to modify, curtail, delay, or suspend some or all aspects of its planned operations. BioTime’s determination as to when it will seek new financing and the amount of financing that it will need will be based on BioTime’s evaluation of the progress it makes in its research and development programs, any changes to the scope and focus of those programs, any changes in grant funding for certain of those programs, and projection of future costs, revenues, and rates of expenditure. BioTime may be required to delay, postpone, or cancel clinical trials or limit the number of clinical trial sites, unless it is able to obtain adequate financing. In addition, BioTime has incurred and expects to continue incurring significant costs in connection with the acquisition of Asterias and with integrating its operations. BioTime may incur additional costs to maintain employee morale and to retain key employees. BioTime cannot assure that adequate financing will be available on favorable terms, if at all. Sales of additional equity securities by BioTime or its subsidiaries and affiliates could result in the dilution of the interests of current shareholders.

Business Combinations

Business Combinations

BioTime accounts for business combinations, such as the Asterias Merger completed in March 2019, in accordance with ASC Topic 805, which requires the purchase price to be measured at fair value. When the purchase consideration consists entirely of shares of BioTime’s common stock, BioTime calculates the purchase price by determining the fair value, as of the acquisition date, of shares issued in connection with the closing of the acquisition. BioTime recognizes estimated fair values of the tangible assets and intangible assets acquired, including in-process research and development (“IPR&D”), and liabilities assumed as of the acquisition date, and records as goodwill any amount of the fair value of the tangible and intangible assets acquired and liabilities assumed in excess of the purchase price.

Equity Method Investments at Fair Value

Equity method investments 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 a 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 in other income and expenses, net.

As further discussed in Note 4, BioTime has elected to account for its OncoCyte shares at fair value using the equity method of accounting because beginning on February 17, 2017, the respective date on which BioTime deconsolidated OncoCyte, BioTime has not had control of OncoCyte, as defined by GAAP, but continues to exercise significant influence over this company. Under the fair value method, BioTime’s value in shares of common stock it holds in OncoCyte is marked to market at each balance sheet date using the closing price of OncoCyte common stock on the NYSE American multiplied by the number of shares of OncoCyte held by BioTime, with changes in the fair value of the OncoCyte shares included in other income and expenses, net, in the consolidated statements of operations. The OncoCyte shares are considered level 1 assets as defined by ASC 820, Fair Value Measurements and Disclosures.

Prior to the Asterias Merger completed on March 8, 2019 discussed in Note 3, BioTime accounted for its Asterias shares held at fair value, using the equity method of accounting.

Revenue Recognition

Revenue Recognition

During the first quarter of 2018, BioTime adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) ASU 2014-09, Revenues from Contracts with Customers (Topic 606), which created a single, principle-based revenue recognition model that supersedes and replaces nearly all existing U.S. GAAP revenue recognition guidance. BioTime adopted ASU 2014-09 using the modified retrospective transition method applied to those contracts which were not completed as of the adoption date. Results for reporting periods beginning on January 1, 2018 and thereafter are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with BioTime’s historical revenue recognition accounting under Topic 605.

BioTime recognizes revenue in a manner that depicts the transfer of control of a product or a service to a customer and reflects the amount of the consideration it is entitled to receive in exchange for such product or service. In doing so, BioTime follows a five-step approach: (i) identify the contract with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations, and (v) recognize revenue when (or as) the customer obtains control of the product or service. BioTime considers the terms of a contract and all relevant facts and circumstances when applying the revenue recognition standard. BioTime applies the revenue recognition standard, including the use of any practical expedients, consistently to contracts with similar characteristics and in similar circumstances.

BioTime’s largest source of revenue is currently related to government grants. In applying the provisions of ASU 2014-09, BioTime has determined that government grants are out of the scope of ASU 2014-09 because the government entities do not meet the definition of a “customer”, as defined by ASU 2014-09, as there is not considered to be a transfer of control of good or services to the government entities funding the grant. BioTime has, and will continue to, account for grants received to perform research and development services in accordance with ASC 730-20, Research and Development Arrangements, which requires an assessment, at the inception of the grant, of whether the grant is a liability or a contract to perform research and development services for others. If BioTime or a subsidiary receiving the grant is obligated to repay the grant funds to the grantor regardless of the outcome of the research and development activities, then BioTime is required to estimate and recognize that liability. Alternatively, if BioTime or a subsidiary receiving the grant is not required to repay, or if it is required to repay the grant funds only if the research and development activities are successful, then the grant agreement is accounted for as a contract to perform research and development services for others, in which case, grant revenue is recognized when the related research and development expenses are incurred (see Note 15).

Deferred grant revenues represent grant funds received from the governmental funding agencies for which the allowable expenses have not yet been incurred as of the balance sheet date reported. As of June 30, 2019, deferred grant revenue was immaterial.

Basic and Diluted Net Income (Loss) Per Share Attributable to Common Shareholders

Basic and diluted net income (loss) per share attributable to common shareholders

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 or restricted stock units, subject to repurchase by BioTime, if any, during the period. 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, convertible preferred stock, if any, using the if-converted method, and treasury stock held by subsidiaries, if any.

For the three months ended June 30, 2019, and for the three and six months ended June 30, 2018, BioTime reported a net loss attributable to common shareholders, and therefore, all potentially dilutive common stock was considered antidilutive for those periods. For the six months ended June 30, 2019, BioTime reported net income attributable to common shareholders, and therefore, performed an analysis of common share equivalents to determine their impact on diluted net income, and determined that none of the common share equivalents were dilutive.

The following weighted average 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):

	Three Months Ended June 30, (unaudited)				Six Months Ended June 30, (unaudited)
	2019		2018		2019		2018
Stock options		15,374		8,990		15,103		8,990
Warrants (1)		-		8,795		-		8,795
BioTime Warrants (2) (Note 3)		1,296		-		917		-
Restricted stock units		271		535		275		535

(1)	The warrants expired on October 1, 2018.
(2)	Although the BioTime Warrants are classified as liabilities, these warrants are considered for dilutive earnings per share calculations in accordance with ASC 260, Earnings Per Share, and determined to be anti-dilutive for the period presented.

Lease Accounting and Impact of Adoption of the New Lease Standard

Lease accounting and impact of adoption of the new lease standard

On January 1, 2019, BioTime adopted ASU 2016-02, Leases (Topic 842, “ASC 842”) and its subsequent amendments affecting BioTime: (i) ASU 2018-10, Codification Improvements to Topic 842, Leases, and (ii) ASU 2018-11, Leases (Topic 842): Targeted improvements, using the modified retrospective method (see Note 15).

BioTime management determines if an arrangement is a lease at inception. Leases are classified as either financing or operating, with classification affecting the pattern of expense recognition in the consolidated statements of operations. When determining whether a lease is a finance lease or an operating lease, ASC 842 does not specifically define criteria to determine “major part of remaining economic life of the underlying asset” and “substantially all of the fair value of the underlying asset.” For lease classification determination, BioTime continues to use (i) greater to or equal to 75% to determine whether the lease term is a major part of the remaining economic life of the underlying asset and (ii) greater to or equal to 90% to determine whether the present value of the sum of lease payments is substantially the fair value of the underlying asset. Under the available practical expedients, BioTime accounts for the lease and non-lease components as a single lease component. BioTime recognizes right-of-use (“ROU”) assets and lease liabilities for leases with terms greater than twelve months in the condensed consolidated balance sheet.

ROU assets represent BioTime’s right to use an underlying asset during the lease term and lease liabilities represent BioTime’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of BioTime’s leases do not provide an implicit rate, BioTime uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. BioTime uses the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. BioTime’s lease terms may include options to extend or terminate the lease when it is reasonably certain that BioTime will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Operating leases are included as right-of-use assets in property and equipment (see Note 15), and ROU lease liabilities, current and long-term, in the condensed consolidated balance sheets. Financing leases are included in property and equipment, and in financing lease liabilities, current and long-term, in BioTime’s condensed consolidated balance sheets.

In connection with the adoption on ASC 842 on January 1, 2019, BioTime derecognized net book value of leasehold improvements and corresponding lease liabilities of $1.9 million and $2.0 million, respectively, which was the carrying value of certain operating leases as of December 31, 2018, included in property and equipment and lease liabilities, respectively, recorded pursuant to build to suit lease accounting under the previous ASC 840 lease standard. The derecognition of these amounts from the superseded ASC 840 lease standard was offset by a cumulative effect adjustment of $0.1 million as a reduction of BioTime’s accumulated deficit on January 1, 2019. These build to suit leases were primarily related to the Alameda and the Cell Cure Leases described in Note 15. ASC 842 requires build to suit leases recognized on BioTime’s consolidated balance sheets as of December 31, 2018 to be derecognized upon the adoption of the new lease standard and be recognized in accordance with the new standard on January 1, 2019.

The adoption of ASC 842 had a material impact in BioTime’s consolidated balance sheets, with the most significant impact resulting from the recognition of ROU assets and lease liabilities for operating leases with remaining terms greater than twelve months on the adoption date (see Note 15). BioTime’s accounting for financing leases (previously referred to as “capital leases”) remained substantially unchanged. 

Other Recently Adopted Accounting Pronouncements

Other recently adopted accounting pronouncements

Adoption of ASU 2016-18, Statement of Cash Flows (Topic 230) - On January 1, 2018, BioTime adopted ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents and restricted cash, and that restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the condensed consolidated statements of cash flows. The adoption of ASU 2016-18 did not have a material effect on BioTime’s condensed consolidated financial statements. However, prior period restricted cash balances included in prepaid expenses and other current assets, and in deposits and other long-term assets, on the condensed consolidated balance sheets was added to the beginning-of-period and end-of-period total consolidated cash and cash equivalents in the condensed consolidated statements of cash flows to conform to the current presentation shown below.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the condensed consolidated balance sheet dates that comprise the total of the same such amounts shown in the condensed consolidated statements of cash flows for all periods presented herein and effected by the adoption of ASU 2016-18 (in thousands):

	June 30, 2019		December 31, 2018		June 30, 2018		December 31, 2017
		(unaudited)				(unaudited)
Cash and cash equivalents	$	8,210	$	23,587	$	27,207	$	36,838
Restricted cash included in prepaid expenses and other current assets (see Note 15)		-		346		346		-
Restricted cash included in deposits and other long-term assets (see Note 15)		586		466		78		847
Total cash, cash equivalents, and restricted cash as shown in the condensed consolidated statements of cash flows	$	8,796	$	24,399	$	27,631	$	37,685

Adoption of ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting - In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for non-employee share-based payment transactions. The new standard expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. ASU 2018-07 is effective for fiscal years beginning after December 15, 2018 (including interim periods within that fiscal year). BioTime adopted ASU 2018-07 on January 1, 2019. As BioTime does not have a significant number of nonemployee share-based awards, the application of the new standard did not have a material impact on its consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Adopted - The recently issued accounting pronouncements applicable to BioTime that are not yet effective should be read in conjunction with the recently issued accounting pronouncements, as applicable and disclosed in BioTime’s Annual Report on Form 10-K for the year ended December 31, 2018.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which modifies certain disclosure requirements for reporting fair value measurements. ASU 2018-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. BioTime will adopt this standard on January 1, 2020 and is currently evaluating the disclosure requirements and its effect on the consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This standard will be effective for interim and annual reporting periods beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for annual periods beginning after December 15, 2018. BioTime has not yet completed its assessment of the impact of the new standard on its consolidated financial statements.
