Accounting Policies [Abstract] |
Nature of Business | 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 March 31, 2016 and for the three months ended March 31, 2016 and 2015 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, 2015 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, 2015. 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.
Reverse Stock Split | Reverse Stock Split We effected a one-for-twelve reverse stock split on May 6, 2016. As a result of the reverse stock split, each twelve shares of the Company’s common stock automatically combined into and became one share of Company common stock. Any fractional shares which would otherwise be due as a result of the reverse split were rounded up to the nearest whole share. Concurrent with the reverse stock split, we reduced the authorized number of common shares from 225 million to 200 million. The reverse stock split will automatically and proportionately adjust, based on the one-for-twelve split ratio, all issued and outstanding shares of our common stock, as well as common stock underlying stock options, warrants and other derivative securities outstanding at the time of the effectiveness of the reverse stock split. The exercise price on outstanding equity based-grants will proportionately increase, while the number of shares available under our equity-based plans will also be proportionately reduced. Share and per share data (except par value) for the periods presented reflect the effects of this reverse stock split. References to numbers of shares of common stock and per share data in the accompanying financial statements and notes thereto have been adjusted to reflect the reverse stock split on a retroactive basis.
Principles of Consolidation | 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.
Use of Estimates | 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 6, “Stock-Based Compensation”);
• |  | the fair value of warrants recorded as a liability (see Note 9, “Warrant Liability”).
Financial Instruments | 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 | 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 666,667 shares at $16.80 per share and Series B Warrants with a ninety trading day term to purchase 666,667 units at $15.00 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 225,000 Series B Warrants were exercised. For the exercise of these warrants, we issued 225,000 shares of our common stock and 225,000 Series A Warrants. The remaining 441,667 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 $16.80 per share to $8.40 per share. Subsequently, as a result of our sale of shares of our common stock under a sales agreement entered into in 2009 and amended in 2012, the exercise price of the outstanding Series A warrants was reduced from $8.40 per share to $6.24 per share and as a result of our March 2016 financing, the exercise price of these warrants was reduced to approximately $3.60 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 9, “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 research and development (R&D) programs and its effect 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 2011 Series A warrant liability at March 31, 2016, was approximately $512,000. In March 2016, we raised gross proceeds of approximately $8,000,000 through an underwritten public offering of 2,222,250 units, at a price of $3.60 per unit, before deducting underwriting discounts and other offering expenses. Each unit consists of a fixed combination of one share of our common stock, a Series A Warrant to purchase 0.50 of a share of our common stock, and a Series B Warrant to purchase 0.75 of a share of our common stock. Each Series A Warrant has an exercise price of $3.60 per share, is immediately exercisable, and will expire two years from the date of issuance. Each Series B Warrant has an exercise price of $5.04 per share, will become exercisable upon stockholder approval of an increase in our authorized capital and the one-year anniversary of the issuance date, whichever is later, and will expire on the fifth anniversary of the date they become exercisable. In connection with the offering, we granted the underwriters a 45-day option to purchase up to an additional 333,338 shares of our common stock and/or warrants to purchase up to an additional 416,672 shares of our common stock to cover over-allotments, if any. The option was exercised in part and we issued an additional 166,473 of Series A warrants and 249,709 of Series B Warrants. The Series A and Series B Warrants contain full ratchet anti-dilution price protection for two years 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 respective warrants, the exercise price of these warrants will be reset to the lower common stock sales price. The initial shares and warrants were offered under our effective shelf registration statement previously filed with the SEC. We intend to file a subsequent registration statement to register the common shares issuable when the Series B Warrants become exercisable. As terms of the Series A and Series B 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 and Series B Warrants is determined using a Monte Carlo simulation model (see Note 9, “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 effect 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 for the 2016 Series A and 2016 Series B warrants at March 31, 2016, was approximately $1,761,000 and $3,887,000 respectively.
Intangible Assets (Patent and License Costs) | Intangible Assets (Patent and License Costs) Other intangible assets, net were approximately $42,000 at March 31, 2016. Intangible assets with finite useful lives are amortized generally on a straight-line basis over the periods benefited. Intangible assets deemed to have indefinite lives are not amortized but are subject to annual impairment tests. Intangible assets are also reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. 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 license agreement.
Revenue Recognition | 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 | Stock-Based Compensation U.S. GAAP requires us to recognize expense related to the fair value of our stock-based payment awards, including employee stock options and restricted stock units. Under the provisions of U.S. GAAP, the fair value of our employee stock-based payment awards is estimated at the date of grant using the Black-Scholes-Merton (Black-Scholes) option-pricing model and is recognized as expense ratably over the requisite service period. The requisite service period is the period over which the awards vest. Stock-based awards may vest over a period of time from the date of grant or upon the attainment of certain established performance milestones. For awards with performance milestones, the expense is recorded over the service period when the achievement of the milestone is probable. The Black-Scholes option-pricing model requires the use of certain assumptions, the most significant of which are our estimates of the expected volatility of the market price of our stock and the expected term of the award. Our estimate of the expected volatility is based on historical volatility. The expected term represents our estimated period during which our stock-based awards remain outstanding. We estimate the expected term based on historical experience of similar awards, giving consideration to the contractual terms of the awards, vesting requirements, and expectation of future employee behavior, including post-vesting terminations. See Note 6, “Stock-Based Compensation” for further information.
Per Share Data | 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:
|  | 2016 |  |  | 2015 |
Net loss |  | $ | (9,561,405 | ) |  | $ | (9,350,701 | )
Weighted average shares outstanding used to compute basic and diluted net income or loss per share |  |  | 9,805,478 |  |  |  | 5,768,331 |
Basic and diluted net loss per share |  | $ | (0.98 | ) |  | $ | (1.62 | )
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 March 31:
|  | 2016 |  |  | 2015 |
Options |  |  | 155,831 |  |  |  | 23,020 |
Restricted stock units |  |  | 810,946 |  |  |  | 832,044 |
Warrants |  |  | 6,883,814 |  |  |  | 1,956,516 |
Total |  |  | 7,850,591 |  |  |  | 2,811,580 |
Comprehensive Income (Loss) | 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 $46,913 as of March 31, 2016, and accumulated other comprehensive income was $47,359, as of December 31, 2015.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In June 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period”. The ASU requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. In July 2015, the FASB voted to defer the effective date of this ASU for one year, revising the effective date for interim and annual periods beginning after December 15, 2016. Early adoption is permitted. We do not anticipate the adoption of this ASU will have a material impact on our consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”, which provides guidance on determining when and how reporting entities must disclose going-concern uncertainties in their financial statements. The ASU requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date of issuance of the entity’s financial statements (or within one year after the date on which the financial statements are available to be issued, when applicable). Further, an entity must provide certain disclosures if there is “substantial doubt about the entity’s ability to continue as a going concern.” This ASU is effective for annual periods ending after December 15, 2017, and interim periods thereafter; early adoption is permitted. In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities,” The amendments in this Update require all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments in this ASU also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition the amendments in this ASU requires disclosure of the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. This ASU is effective for fiscal years beginning after December 15, 2017. The adoption of the ASU will not have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases”. The amendments in this Update create Topic 842, “Leases”, and supersede the leases requirements in Topic 840, “Leases”. Topic 842 specifies the accounting for leases. The objective of Topic 842 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Topic 842 affects any entity that enters into a lease with some specified scope exemptions. The amendments in this Update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the provisions of ASU 2016-02 and its impact on our consolidated financial statements and related disclosures.
