Summary of Significant Accounting Policies | Note 1. Summary of Significant Accounting Policies Nature of Business. StemCells, Inc., a Delaware corporation, is a biopharmaceutical company that operates in one segment, the research, development, and commercialization of stem cell therapeutics and related technologies. The accompanying financial data as of June 30, 2015 and for the three and six months ended June 30, 2015 and 2014 have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) have been condensed or omitted pursuant to these rules and regulations. The December 31, 2014 condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. However, we believe that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014. We have incurred significant operating losses since inception. We expect to incur additional operating losses over the foreseeable future. We have very limited liquidity and capital resources and must obtain significant additional capital and other resources in order to provide funding for our product development efforts, the acquisition of technologies, businesses and intellectual property rights, preclinical and clinical testing of our products, pursuit of regulatory approvals, acquisition of capital equipment, laboratory and office facilities, establishment of production capabilities, general and administrative expenses and other working capital requirements. We rely on our cash reserves, proceeds from equity and debt offerings, credit facilities, proceeds from the transfer or sale of intellectual property rights, equipment, facilities or investments, government grants and funding from collaborative arrangements, to fund our operations. If we exhaust our cash reserves and are unable to obtain adequate financing, we may be unable to meet our operating obligations and we may be required to initiate bankruptcy proceedings. The financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty. Principles of Consolidation The condensed consolidated financial statements include the accounts of StemCells, Inc., and our wholly-owned subsidiaries, including StemCells California, Inc., Stem Cell Sciences Holdings Ltd, and Stem Cell Sciences (UK) Ltd (SCS). All significant intercompany accounts and transactions have been eliminated. Reclassifications Certain reclassifications have been made to the prior year financial statements in order to conform to the current year’s presentation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Actual results could differ materially from these estimates. Significant estimates include the following: • the grant date fair value of stock-based awards recognized as compensation expense (see Note 5, “Stock-Based Compensation”); and • the fair value of warrants recorded as a liability (see Note 8, “Warrant Liability”). Discontinued Operations The results of operations of a business that either has been disposed of or is classified as held-for-sale are reported in discontinued operations if the operations and cash flows of the component have been or will be eliminated from our ongoing operations as a result of the disposal transaction and we will not have any significant continuing involvement in the operations of the component after the disposal transaction. We present the operations of a business that meet this criteria as a discontinued operation, and retrospectively reclassify operating results for all prior periods presented. In the fourth quarter of 2014, as part of our strategy to focus on our clinical operations, we sold our SC Proven reagent and cell culture business and wound-down our business operations at our Stem Cell Sciences Subsidiary in Cambridge, UK (SCS). The results of operations for this component have been classified as discontinued operations for all periods in our Consolidated Statement of Operations. Financial Instruments Cash and Cash Equivalents Cash equivalents are money market accounts, money market funds and investments with maturities of 90 days or less from the date of purchase. Receivables Our receivables generally consist of interest income on our financial instruments and royalties due from licensing agreements. Warrant Liability We account for our warrants in accordance with U.S. GAAP which defines how freestanding contracts that are indexed to and potentially settled in a company’s own stock should be measured and classified. Authoritative accounting guidance prescribes that only warrants issued by us under contracts that cannot be net-cash settled, and are both indexed to and settled in our common stock, can be classified as equity. As part of our December 2011 financing, we issued Series A Warrants with a five year term to purchase 8,000,000 shares at $1.40 per share and Series B Warrants with a ninety trading day term to purchase 8,000,000 units at $1.25 per unit. Each unit underlying the Series B Warrants consisted of one share of our common stock and one Series A Warrant. In the first and second quarter of 2012, an aggregate of 2,700,000 Series B Warrants were exercised. For the exercise of these warrants, we issued 2,700,000 shares of our common stock and 2,700,000 Series A Warrants. The remaining 5,300,000 Series B Warrants expired unexercised by their terms on May 2, 2012. The Series A Warrants contain full ratchet anti-dilution price protection so that, in most situations, upon the issuance of any common stock or securities convertible into common stock at a price below the then-existing exercise price of the Series A Warrants, the Series A exercise price will be reset to the lower common stock sales price As a result of our April 2015 financing, the exercise price of the outstanding Series A warrants were reduced from $1.40 per share to $0.6999999 per share. As terms of the Series A Warrants do not meet the specific conditions for equity classification, we are required to classify the fair value of these warrants as a liability, with subsequent changes in fair value to be recorded as income (loss) due to change in fair value of warrant liability. The fair value of the Series A Warrants is determined using a Monte Carlo simulation model (see Note 8, “Warrant Liability”). The fair value is affected by changes in inputs to these models including our stock price, expected stock price volatility, the contractual term, and the risk-free interest rate. The use of a Monte Carlo simulation model requires input of additional assumptions including the progress of our R&D programs and its affect on potential future financings. We will continue to classify the fair value of the warrants as a liability until the warrants are exercised, expire or are amended in a way that would no longer require these warrants to be classified as a liability. The estimated fair value of our warrant liability at June 30, 2015, was approximately $1,044,000. Intangible Assets Prior to fiscal year 2001, we capitalized certain patent costs, which are being amortized over the estimated life of the patent and would be expensed at the time such patents are deemed to have no continuing value. Since 2001, all patent costs are expensed as incurred. License costs are capitalized and amortized over the estimated life of the related license agreement. Revenue Recognition We currently recognize revenue resulting from the licensing and use of our technology and intellectual property. Licensing agreements may contain multiple elements, such as upfront fees, payments related to the achievement of particular milestones and royalties. Revenue from upfront fees for licensing agreements that contain multiple elements are generally deferred and recognized on a straight-line basis over the term of the agreement. Fees associated with substantive at risk performance-based milestones are recognized as revenue upon completion of the scientific or regulatory event specified in the agreement, and royalties received are recognized as earned. Revenue from licensing agreements is recognized net of a fixed percentage due to licensors as royalties. Stock-Based Compensation Compensation expense for stock-based payment awards to employees is based on their grant date fair value as calculated and amortized over their vesting period. See Note 5, “Stock-Based Compensation” for further information. We use the Black-Scholes model to calculate the fair value of stock-based awards. Per Share Data Basic net income or loss per share is computed by dividing net income or loss by the weighted average number of shares of common stock outstanding during the period. Diluted net income or loss per share is computed based on the weighted average number of shares of common stock and other dilutive securities. To the extent these securities are anti-dilutive, they are excluded from the calculation of diluted earnings per share. The following is a reconciliation of the numerators and denominators of the basic and diluted net loss per share computations: Three months ended June 30, Six months ended June 30, 2015 2014 2015 2014 Net loss from continuing operations $ (8,461,714 ) $ (11,970,735 ) $ (17,812,415 ) $ (19,533,263 ) Net loss from discontinued operations — (144,489 ) — (202,217 ) Net loss $ (8,461,714 ) $ (12,115,224 ) $ (17,812,415 ) $ (19,735,480 ) Weighted average shares outstanding used to compute basic and diluted net income or loss per share 95,190,823 55,711,717 82,277,137 55,529,818 Basic and diluted net loss per share from continuing operations $ (0.09 ) $ (0.22 ) $ (0.22 ) $ (0.36 ) Basic and diluted net loss per share from discontinued operations — — — — Basic and diluted net loss per share $ (0.09 ) $ (0.22 ) $ (0.22 ) $ (0.36 ) The following outstanding potentially dilutive securities were excluded from the computation of diluted net income or loss per share because the effect would have been anti-dilutive as of June 30: 2015 2014 Options 2,765,229 375,670 Restricted stock units 9,358,518 3,137,440 Warrants 53,882,369 14,207,426 Total 66,006,116 17,720,536 Comprehensive Income (Loss) Comprehensive income (loss) is comprised of net income or loss and other comprehensive income or loss (OCL). OCL includes certain changes in stockholders’ equity that are excluded from net income or loss. Specifically, when applicable, we include in OCL changes in unrealized gains and losses on foreign currency translations. Accumulated other comprehensive income was $49,800 as of June 30, 2015, and accumulated other comprehensive income was $65,390, as of December 31, 2014. |
