Our approaches are driven by three platform technologies: | ||
• | our antibody platform, including our proprietary Retrocyte Display™ technology designed to produce quality human monoclonal antibodies, currently focused on advancing checkpoint modulators, or CPMs; | |
• | our heat shock protein (HSP)-based vaccines, either autologous or recombinant; and | |
• | our saponin-based vaccine adjuvants, principally our QS-21 Stimulon® adjuvant, or QS-21 Stimulon. | |
We have a portfolio of programs in pre-clinical and clinical stages, including a series of CPMs in investigational new drug (IND)-enabling studies, our Prophage Series vaccine, a Phase 3 ready HSP-based autologous vaccine for a form of brain cancer and a number of advanced QS-21 Stimulon-containing vaccine candidates in late stage development by our licensee. | ||
Our core technologies include Retrocyte Display™, a powerful proprietary platform designed to effectively discover and optimize novel, fully human and humanized monoclonal antibodies against antigens of interest. For the last several years, our Retrocyte Display™ platform has been applied to the discovery and development of CPMs targeting significant checkpoint targets. Through collaborative arrangements with our partners, we have preclinical programs targeting GITR, OX40, CTLA-4, LAG-3, TIM-3 and PD-1. We have completed the following Phase 2 trials for HSP-based vaccines for cancer and infectious disease: (1) Prophage autologous HSP-based vaccine in newly diagnosed glioblastoma multiforme (GBM) and (2) HerpV recombinant HSP70-synthetic peptide vaccine for the treatment of herpes simplex virus 2 (HSV2) infection. Our QS-21 Stimulon adjuvant platform is extensively partnered with GlaxoSmithKline (GSK). | ||
Our business activities have included product research and development, intellectual property prosecution, | ||
manufacturing, regulatory and clinical affairs, corporate finance and development activities, and support of our collaborations. | ||
Our product candidates require clinical trials and approvals from regulatory agencies, as well as acceptance in the marketplace. | ||
Part of our strategy is to develop and commercialize some of our product candidates by continuing our existing arrangements | ||
with academic and corporate collaborators and licensees and by entering into new collaborations. | ||
We have incurred significant losses since our inception. As of December 31, 2014, we had an accumulated deficit of $691.3 million. Since our inception, we have financed our operations primarily through the sale of equity and convertible and other notes, and interest income earned on cash, cash equivalents, and short-term investment balances. We believe that, based on our current plans and activities, our cash, cash equivalents and short-term investments balance of $40.2 million as of December 31, 2014, plus proceeds of $60.0 million received in February 2015 from our global alliance with, and related equity investment by, Incyte and $9.0 million received in February 2015 from our issuance of senior subordinated promissory notes (see Note 20), will be sufficient to satisfy our liquidity requirements through the first half of 2016. We continue to monitor the likelihood of success of our key initiatives and are prepared to discontinue funding of such activities if they do not prove to be feasible, restrict capital expenditures and/or reduce the scale of our operations. | ||
Research and development program costs include compensation and other direct costs plus an allocation of indirect costs, based on certain assumptions, and our review of the status of each program. Our product candidates are in various stages of development and significant additional expenditures will be required if we start new trials, encounter delays in our programs, apply for regulatory approvals, continue development of our technologies, expand our operations, and/or bring our product candidates to market. The eventual total cost of each clinical trial is dependent on a number of factors such as trial design, length of the trial, number of clinical sites, and number of patients. The process of obtaining and maintaining regulatory approvals for new therapeutic products is lengthy, expensive, and uncertain. Because our CPM antibody programs are pre-clinical and because further development of HerpV and our Prophage Series vaccines are dependent on successful partnering or funding efforts, among other factors, we are unable to reliably estimate the cost of completing research and development programs, the timing of bringing such programs to various markets, or substantial partnering or out-licensing arrangements, and, therefore, are unable to determine when, if ever, material cash inflows from operating activities are likely to commence. We will continue to adjust our spending as needed in order to preserve liquidity. |

Dec. 31, 2014 | |||||||||
Accounting Policies [Abstract] | |||||||||
Significant Accounting Policies [Text Block] | Summary of Significant Accounting Policies | ||||||||
(a) Basis of Presentation and Principles of Consolidation | |||||||||
The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles and include the accounts of Agenus and our wholly-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated in consolidation. | |||||||||
(b) Segment Information | |||||||||
We are managed and operated as one business. The entire business is managed by a single executive operating committee that reports to the chief executive officer. We do not operate separate lines of business with respect to any of our product candidates. Accordingly, we do not prepare discrete financial information with respect to separate product areas or by location and do not have separately reportable segments as defined by Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 280, Segment Reporting. | |||||||||
(c) Use of Estimates | |||||||||
The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. We base those estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates. | |||||||||
(d) Cash and Cash Equivalents | |||||||||
We consider all highly liquid investments purchased with maturities at acquisition of three months or less to be cash equivalents. Cash equivalents consist primarily of money market funds. | |||||||||
(e) Investments | |||||||||
We classify investments in marketable securities at the time of purchase. At December 31, 2014, all marketable securities are classified as available for sale and as such, the investments are recorded at fair value. Gains and losses on the sale of marketable securities are recognized in operations based on the specific identification method. At December 31, 2014, our investments consisted of institutional money market funds and U.S. treasury bills. | |||||||||
(f) Concentrations of Credit Risk | |||||||||
Financial instruments that potentially subject us to concentrations of credit risk are primarily cash equivalents, investments, and accounts receivable. We invest our cash, cash equivalents and short-term investments in accordance with our investment policy, which specifies high credit quality standards and limits the amount of credit exposure from any single issue, issuer, or type of investment. We carry balances in excess of federally insured levels, however, we have not experienced any losses to date from this practice. | |||||||||
(g) Inventories | |||||||||
Inventories are stated at the lower of cost or market. Cost has been determined using standard costs that approximate the first-in, first-out method. Inventory as of December 31, 2014 consisted solely of finished goods. | |||||||||
(h) Plant and Equipment | |||||||||
Plant and equipment, including software developed for internal use, are carried at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Amortization of leasehold improvements is computed over the shorter of the lease term or estimated useful life of the asset. Additions and improvements are capitalized, while repairs and maintenance are charged to expense as incurred. Amortization and depreciation of plant and equipment was $1.1 million, $586,000, and $1.6 million, for the years ended December 31, 2014, 2013, and 2012, respectively. | |||||||||
(i) Fair Value of Financial Instruments | |||||||||
The estimated fair values of all of our financial instruments, excluding debt, approximate their carrying amounts in the consolidated balance sheets. The fair value of our outstanding debt is based on a present value methodology. The outstanding principal amount of our debt, including the current portion, was $6.3 million and $9.6 million at December 31, 2014 and 2013, respectively. | |||||||||
(j) Revenue Recognition | |||||||||
Revenue for services under research and development contracts are recognized as the services are performed, or as clinical trial materials are provided. Non-refundable milestone payments that represent the completion of a separate earnings process are recognized as revenue when earned. License fees and royalties are recognized as they are earned. Grant revenue is recognized when the associate expense is recorded. Revenue recognized from collaborative agreements is based upon the provisions of ASC 605-25, Revenue Recognition – Multiple-Element Arrangements, as amended by Accounting Standards Update 2009-13. For the years ended December 31, 2014, 2013, and 2012, 48%, 44%, and 49%, respectively, of our revenue was earned from one research partner. In addition, 40% of our revenue for the year December 31, 2012, was earned from one of our licensees and 47% and 9%, of our revenue for the years ended December 31, 2013 and 2012, respectively, was earned from one service customer. The revenues from the licensee did not continue past 2012 and the revenue from the service customer did not continue past 2013. | |||||||||
(k) Foreign Currency Transactions | |||||||||
Gains and losses from our foreign currency based accounts and transactions, such as those resulting from the translation and settlement of receivables and payables denominated in foreign currencies, are included in the consolidated statements of operations within other income (expense). We do not currently use derivative financial instruments to manage the risks associated with foreign currency fluctuations. We recorded foreign currency losses of $773,000, $9,000, and $11,000, for the years ended December 31, 2014, 2013, and 2012, respectively. | |||||||||
(l) Research and Development | |||||||||
Research and development expenses include the costs associated with our internal research and development activities, including salaries and benefits, share-based compensation, occupancy costs, clinical manufacturing costs, related administrative costs, and research and development conducted for us by outside advisors, such as sponsored university-based research partners and clinical study partners. We account for our clinical study costs by estimating the total cost to treat a patient in each clinical trial and recognizing this cost based on estimates of when the patient receives treatment, beginning when the patient enrolls in the trial. Research and development expenses also include the cost of clinical trial materials shipped to our research partners. Research and development costs are expensed as incurred. | |||||||||
(m) Share-Based Compensation | |||||||||
We account for share-based compensation in accordance with the provisions of ASC 718, Compensation—Stock Compensation and ASC 505-50, Equity-Based Payments to Non-Employees. Share-based compensation expense is recognized based on the estimated grant date fair value, and is recognized net of an estimated forfeiture rate such that we recognize compensation cost for those shares expected to vest. Compensation cost is recognized on a straight-line basis over the requisite service period of the award. The non-cash charge to operations for non-employee options with vesting or other performance criteria is affected each reporting period by changes in the fair value of our common stock. Under the provisions of ASC 505-50, the change in fair value of vested options issued to non-employees is reflected in the statement of operations each reporting period, until the options are exercised or expire. See Note 10 for a further discussion on share-based compensation. | |||||||||
(n) Income Taxes | |||||||||
Income taxes are accounted for under the asset and liability method with deferred tax assets and liabilities recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which such items are expected to be reversed or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the consolidated statement of operations in the period that includes the enactment date. Deferred tax assets are recorded when they more likely than not are expected to be realized. | |||||||||
(o) Net Loss Per Share | |||||||||
Basic income and loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding (including common shares issuable under our Directors’ Deferred Compensation Plan). Diluted income per common share is calculated by dividing net income attributable to common stockholders by the weighted average number of common shares outstanding (including common shares issuable under our Directors’ Deferred Compensation Plan) plus the dilutive effect of outstanding instruments such as warrants, stock options, nonvested shares, convertible preferred stock, and convertible notes. Because we reported a net loss attributable to common stockholders for all periods presented, diluted loss per common share is the same as basic loss per common share, as the effect of utilizing the fully diluted share count would have reduced the net loss per common share. Therefore, the following potentially dilutive securities have been excluded from the computation of diluted weighted average shares outstanding as of December 31, 2014, 2013, and 2012, as they would be anti-dilutive: | |||||||||
At December 31, | |||||||||
2014 | 2013 | 2012 | |||||||
Warrants | 2,951,450 | 3,280,396 | 3,309,378 | ||||||
Stock options | 6,525,724 | 4,163,100 | 2,748,883 | ||||||
Nonvested shares | 78,828 | 147,274 | 249,968 | ||||||
Convertible preferred stock | 333,333 | 333,333 | 333,333 | ||||||
(p) Goodwill | |||||||||
Goodwill represents the excess of cost over the fair value of net assets of businesses acquired. Goodwill is not amortized, but instead tested for impairment at least annually. Annually we assess whether there is an indication that goodwill is impaired, or more frequently if events and circumstances indicate that the asset might be impaired during the year. We perform our annual impairment test as of October 31 of each year. The first step of our impairment analysis compares our fair value to our net book value to determine if there is an indicator of impairment. We operate as a single operating segment and single reporting unit and our fair value is based on our quoted market price of our common stock to derive the market capitalization as of the date of the impairment test. ASC 350, Intangibles, Goodwill and Other states that if the carrying value of the reporting unit is negative, the second step of the impairment test shall be performed to measure the amount of impairment loss, if any, if qualitative factors indicate that it is more likely than not that a goodwill impairment exists. No goodwill impairment has been recognized for the periods presented. | |||||||||
(q) In-process Research and Development | |||||||||
Acquired in-process research and development ("IPR&D") represents the fair value assigned to research and development assets that have not reached technological feasibility. The value assigned to acquired IPR&D is determined by estimating the costs to develop the acquired technology into commercially viable products, estimating the resulting revenue from the projects, and discounting the net cash flows to present value. The revenue and costs projections used to value acquired IPR&D are, as applicable, reduced based on the probability of success of developing a new drug. Additionally, the projections consider the relevant market sizes and growth factors, expected trends in technology, and the nature and expected timing of new product introductions by us and our competitors. The rates utilized to discount the net cash flows to their present value are commensurate with the stage of development of the projects and uncertainties in the economic estimates used in the projections. Upon the acquisition of IPR&D, we complete an assessment of whether our acquisition constitutes the purchase of a single asset or a group of assets. We consider multiple factors in this assessment, including the nature of the technology acquired, the presence or absence of separate cash flows, the development process and stage of completion, quantitative significance and our rationale for entering into the transaction. | |||||||||
If we acquire an asset or group of assets that do not meet the definition of a business under applicable accounting standards, then the acquired IPR&D is expensed on its acquisition date. Future costs to develop these assets are recorded to research and development expense as they are incurred. | |||||||||
We review amounts capitalized as acquired IPR&D for impairment at least annually, as of October 31, and whenever events or changes in circumstances indicate that the carrying value of the assets might not be recoverable. When performing our impairment assessment, we have the option to first assess qualitative factors to determine whether it is necessary to recalculate the fair value of our acquired IPR&D. If we elect this option and believe, as a result of the qualitative assessment, that it is more-likely-than-not that the fair value of our acquired IPR&D is less than its carrying amount, we calculate the fair value using the same methodology as described above. If the carrying value of our acquired IPR&D exceeds its fair value, then the intangible asset is written-down to its fair value. Alternatively, we may elect to not first assess qualitative factors and immediately recalculate the fair value of our acquired IPR&D. No IPR&D impairments were recognized for the years presented. | |||||||||
(r) Accounting for Asset Retirement Obligations | |||||||||
We record the fair value of an asset retirement obligation as a liability in the period in which we incur a legal obligation associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development, and/or normal use of the assets. A legal obligation is a liability that a party is required to settle as a result of an existing or enacted law, statute, ordinance, or contract. We are also required to record a corresponding asset that is depreciated over the life of the asset. Subsequent to the initial measurement of the asset retirement obligation, the obligation will be adjusted at the end of each period to reflect the passage of time (accretion) and changes in the estimated future cash flows underlying the obligation. Changes in the liability due to accretion are charged to the consolidated statement of operations, whereas changes due to the timing or amount of cash flows are an adjustment to the carrying amount of the related asset. Our asset retirement obligations primarily relate to the expiration of our facility lease and anticipated costs to be incurred based on our lease terms. | |||||||||
(s) Long-lived Assets | |||||||||
If required based on certain events and circumstances, recoverability of assets to be held and used, other than goodwill and intangible assets not being amortized, is measured by a comparison of the carrying amount of an asset to the undiscounted future net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Authoritative guidance requires companies to separately report discontinued operations and extends that reporting to a component of an entity that either has been disposed of (by sale, abandonment, or in a distribution to owners) or is classified as held for sale. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. | |||||||||
(t) Recent Accounting Pronouncements | |||||||||
In July 2013, the FASB issued Accounting Standards Update No. 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists", ("ASU 2013-11"). ASU 2013-11 amends ASC 740, "Income Taxes", by providing guidance on the financial statement presentation of an unrecognized benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 does not affect the recognition or measurement of uncertain tax positions under ASC 740. ASU 2013-11 is effective for interim and annual periods beginning after December 15, 2013, with early adoption permitted. The adoption of ASU 2013-11 did not have an impact on our consolidated financial statements. | |||||||||
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, ("ASU 2014-09"). ASU 2014-09 amends revenue recognition principles and provides a single set of criteria for revenue recognition among all industries. This new standard provides a five step framework whereby revenue is recognized when promised goods or services are transferred to a customer at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires enhanced disclosures pertaining to revenue recognition in both interim and annual periods. ASU 2014-09 is effective for interim and annual periods beginning after December 15, 2016. We are currently evaluating the potential impact that ASU 2014-09 may have on our consolidated financial statements and related disclosures. | |||||||||
In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern, ("ASU 2014-15"). ASU 2014-15 describes how an entity should assess its ability to meet obligations and sets rules for how this information should be disclosed in the financial statements. The standard provides guidance that will be used along with existing auditing standards. ASU 2014-15 applies to all entities and is effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter with early adoption permitted. We are currently evaluating the potential impact that ASU 2014-15 may have on our consolidated financial statements and related disclosures. |

Business Combination [Abstract] | ||||||||
Business Combination Disclosure [Text Block] | 4-Antibody Acquisition | |||||||
On January 10, 2014, we entered into a Share Exchange Agreement (the "Share Exchange Agreement") providing for our acquisition of all of the outstanding capital stock of 4-Antibody AG (" 4-AB"), from the shareholders of 4-AB (the “4-AB Shareholders”). The transaction closed on February 12, 2014 (the "Closing Date"). In exchange for their shares, the 4-AB Shareholders received an aggregate of 3,334,079 shares of our common stock paid upon closing and valued at $10.1 million. Contingent milestone payments of up to $40 million (the "contingent purchase price consideration"), payable in cash or shares of our common stock at our option, will be due to the 4-AB Shareholders as follows: (i) $20 million upon our market capitalization exceeding $300 million for 10 consecutive trading days prior to the earliest of (a) the fifth anniversary of the Closing Date (b) the sale of the 4-AB or (c) the sale of Agenus; (ii) $10 million upon our market capitalization exceeding $750 million for 30 consecutive trading days prior to the earliest of (a) the tenth anniversary of the Closing Date (b) the sale of 4-AB, or (c) the sale of Agenus, and (iii) $10 million upon our market capitalization exceeding $1 billion for 30 consecutive trading days prior to the earliest of (a) the tenth anniversary of the Closing Date, (b) the sale of 4-AB, or (c) the sale of Agenus. We assigned an acquisition date fair value of $9.7 million to the contingent purchase price consideration as of the acquisition date. During January 2015, the first milestone noted above was achieved, see Note 20 for further detail. This acquisition provided us with the Retrocyte DisplayTM technology platform for the rapid discovery and optimization of fully-human and humanized monoclonal antibodies against a wide array of molecular targets and a portfolio of CPM antibodies. | ||||||||
The acquisition of 4-AB was accounted for under the acquisition method of accounting. The purchase price of approximately $19.8 million has been allocated to the tangible and intangible assets acquired and liabilities assumed. | ||||||||

The fair value of the IPR&D and patented technology was determined using the income approach and the relief from royalty rate method, respectively, using significant inputs, including an 18% discount rate, that are not observable. We consider the fair value of the IPR&D and patented technology to be Level 3 due to the significant estimates and assumptions used by management in establishing the estimated fair values. | ||||||||
All of the convertible notes assumed by us in the acquisition were converted into approximately 383,000 shares of our common stock on May 8, 2014. | ||||||||
The following table summarizes the supplemental statements of operations information on an unaudited pro forma basis as if the 4-AB acquisition had occurred on January 1, 2013 (in thousands except per share data): | ||||||||

The weighted average amortization period of our finite-lived intangible assets is 13 years. Amortization expense related to acquired intangibles is estimated at $528,000 for each of the years ending 2015 and 2016, $478,000 for the year ending 2017, $402,000 for the year ending 2018, and $290,000 for each of the years 2019-2028, and $37,000 for the year ending 2029. | ||||||||||||||
The acquired IPR&D asset relates to the six pre-clinical CPM antibody programs acquired in the 4-AB transaction. IPR&D acquired in a business combination is capitalized at fair value until the underlying project is completed and is subject to impairment testing. Once the project is completed, the carrying value of IPR&D is amortized over the estimated useful life of the asset. Post-acquisition research and development expenses related to the acquired IPR&D are expensed as incurred. |

Income Tax Disclosure [Abstract] | ||||||||||||
Income Taxes | Income Taxes | |||||||||||
We are subject to taxation in the U.S. and various state, local, and foreign jurisdictions. We remain subject to examination by U.S. Federal, state, local, and foreign tax authorities for tax years 2011 through 2014. With a few exceptions, we are no longer subject to U.S. Federal, state, local, and foreign examinations by tax authorities for the tax year 2010 and prior. However, net operating losses from the tax year 2010 and prior would be subject to examination if and when used in a future tax return to offset taxable income. Our policy is to recognize income tax related penalties and interest, if any, in our provision for income taxes and, to the extent applicable, in the corresponding income tax assets and liabilities, including any amounts for uncertain tax positions. | ||||||||||||
As of December 31, 2014, we have available net operating loss carryforwards of $555.5 million and $63.9 million for Federal and state income tax purposes, respectively, which are available to offset future Federal and state taxable income, if any, and expire between 2014 and 2033. Our ability to use these net operating losses is limited by change of control provisions under Internal Revenue Code Section 382 and may expire unused. In addition, we have $9.3 million and $7.4 million of Federal and state research and development credits, respectively, available to offset future taxable income. These Federal and state research and development credits expire between 2015 and 2034 and 2017 and 2029, respectively. We also have foreign income tax net operating loss carryforwards of approximately $44.7 million which are available to offset future foreign taxable income, if any, and expire between 2015 and 2021. The potential impacts of such provisions are among the items considered and reflected in management’s assessment of our valuation allowance requirements. | ||||||||||||
The tax effect of temporary differences and net operating loss and tax credit carryforwards that give rise to significant portions of the deferred tax assets and deferred tax liabilities as of December 31, 2014 and 2013 are presented below (in thousands). | ||||||||||||

In assessing the realizablility of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which the net operating loss and tax credit carryforwards can be utilized or the temporary differences become deductible. We consider projected future taxable income and tax planning strategies in making this assessment. In order to fully realize the deferred tax asset, we will need to generate future taxable income sufficient to utilize net operating losses prior to their expiration. Based upon our history of not generating taxable income due to our business activities focused on product development, we believe that it is more likely than not that deferred tax assets will not be realized through future earnings. Accordingly, a valuation allowance has been established for deferred tax assets which will not be offset by the reversal of deferred tax liabilities. The valuation allowance on the deferred tax assets increased by $21.6 million and $9.6 million during the years ended December 31, 2014 and 2013, respectively. The net operating loss includes amounts pertaining to tax deductions relating to stock exercises for which any subsequently recognized tax benefit will be recorded as an increase to additional paid-in capital. | ||||||||||||
Income tax benefit was nil for each of the years ended December 31, 2014, 2013, and 2012, and differed from the amounts computed by applying the U.S. Federal income tax rate of 34% to loss before income taxes as a result of the following (in thousands). | ||||||||||||

Equity [Abstract] | |
Equity | Equity |
Effective April 24, 2014, our certificate of incorporation was amended to increase the authorized number of shares of our common stock from 70,000,000 to 140,000,000. | |
In a private placement in September 2003, we sold 31,620 shares of our series A convertible preferred stock, par value $0.01 per share, ("Series A Preferred Stock") for net proceeds of $31.6 million. In February 2013, we entered into a Securities Exchange Agreement (the “Exchange Agreement”) with the holder of our Series A Preferred Stock pursuant to which the holder exchanged all 31,620 of the outstanding shares of our Series A Preferred Stock for an equivalent number of shares of our Series A-1 Preferred Stock to be issued by us. The terms of the Series A-1 Preferred Stock are materially identical to the Series A Preferred Stock, except that the Series A-1 Preferred Stock accrues a 0.63% annual dividend, as compared to a 2.5% annual dividend for the Series A Preferred Stock. In exchange for this reduction in dividend obligations, we issued to the holder 666,666 shares of our common stock. After giving effect to the transactions contemplated by the Exchange Agreement, no shares of Series A Preferred Stock remain outstanding. | |
Under the terms and conditions of the Certificate of Designation creating the Series A-1 Preferred Stock, this stock is convertible by the holder at any time into our common stock, is non-voting, has an initial conversion price of $94.86 per common share, subject to adjustment, and is redeemable by us at its face amount ($31.6 million), plus any accrued and unpaid dividends, on or after September 24, 2013. The Certificate of Designation does not contemplate a sinking fund. The Series A-1 Preferred Stock ranks senior to our common stock. In a liquidation, dissolution, or winding up of the Company, the Series A-1 Preferred Stock’s liquidation preference must be fully satisfied before any distribution could be made to the holders of the common stock. Other than in such a liquidation, no terms of the Series A-1 Preferred Stock affect our ability to declare or pay dividends on our common stock as long as the Series A-1 Preferred Stock’s dividends are accruing. The liquidation value of this Series A-1 Preferred stock is equal to $1,000 per share outstanding plus any accrued unpaid dividends. Dividends in arrears with respect to the Series A-1 Preferred Stock were approximately $392,000 or $12.40 per share, at December 31, 2014, and dividends in arrears with respect to the Series A Preferred Stock were approximately $650,000, or $20.56 per share, at December 31, 2013. | |
In September 2007, we issued 270,562 shares of our common stock at a price of $18.48 per share to a single institutional investor. In conjunction with this transaction, we also issued to the investor 10,000 shares of our new series B1 convertible preferred stock and 5,250 shares of our new series B2 convertible preferred stock. All shares of the series B1 convertible preferred stock have been converted. Shares of the series B2 convertible preferred stock permit the investor to purchase common shares for consideration of up to 35% of the total dollar amount previously invested pursuant to the agreement with the investor, including conversions of the series B1 convertible preferred stock, at a purchase price equal to the lesser of $24.96 per common share or a price calculated based on the then-prevailing price of our common stock, with such right expiring seven years from the date of issuance. In April 2009, we issued 988,202 shares of our common stock upon conversion of 2,145 shares of our series B2 convertible preferred stock via cashless conversions. Upon completion of the conversions, 3,105 shares of our series B2 convertible preferred stock were still outstanding although no further shares could be converted into shares of common stock (other than in the event of a change of control) as the maximum number of shares (as defined in the agreement) had been issued. The total number of shares of common stock issued or issuable to the holder of the class B convertible preferred stock cannot exceed 19.9% of our outstanding common stock. No dividends are paid on the class B convertible preferred stock and there are no liquidation preferences. On September 7, 2014, all 3,105 shares of our issued and outstanding Series B2 Convertible Preferred Stock remained unconverted and were canceled and extinguished in accordance with the Certificate of Designation. | |
In January 2008, we entered into a private placement agreement (the “January 2008 private placement”) pursuant to which we sold 1,451,450 shares of common stock for $18.00 for each share sold. Investors also received (i) 10-year warrants to purchase, at an exercise price of $18.00 per share, up to 1,451,450 shares of common stock and (ii) unit warrants to purchase, at an exercise price of $18.00 per unit, contingent upon a triggering event as defined in the January 2008 private placement documents, (a) up to 1,451,450 shares of common stock and (b) additional 10-year warrants to purchase, at an exercise price of $18.00 per share, up to 1,451,450 additional shares of common stock. In accordance with the terms of the January 2008 private placement, the 10-year warrants became exercisable for a period of 9.5 years as of July 9, 2008. Our private placement in April 2008 qualified as a triggering event, and therefore the unit warrants became exercisable for a period of eighteen months as of July 9, 2008. The unit warrants expired unexercised in January 2010. In February 2008, we filed a registration statement covering the resale of the 1,451,450 shares of common stock issued and the 1,451,450 shares issuable upon the exercise of the 10-year warrants issued in the January 2008 private placement. The Securities and Exchange Commission (the “SEC”) declared the resale registration statement effective on February 14, 2008. | |
In April 2008, we entered into a private placement agreement (the “April 2008 private placement”) under which we sold (i) 1,166,666 shares of common stock and (ii) five-year warrants to acquire up to 1,166,666 shares of common stock at an exercise price of $22.50 per share, for $18.00 for each share and warrant sold. The warrants became exercisable for a period of 4.5 years as of October 10, 2008. In April 2008, we filed a registration statement covering the resale of the 1,166,666 shares of common stock issued and the 1,166,666 shares issuable upon the exercise of the related warrants issued in the April 2008 private placement. The SEC declared the resale registration statement effective on May 7, 2008. These warrants expired unexercised April 2013. | |
In July 2009, we entered into a private placement agreement under which we issued and sold (i) 833,333 shares of our common stock, (ii) six-month warrants to purchase up to 416,666 additional shares of common stock at an exercise price of $12.00 per share, and (iii) four-year warrants to purchase up to 362,316 additional shares of common stock at an exercise price of $13.80 per share, for $12.00 for each share sold generating gross proceeds of $10.0 million. Subsequently, we filed, and the SEC declared effective, a registration statement covering the resale of the 833,333 shares of common stock issued and the 778,982 shares issuable upon the exercise of the related warrants issued in this private placement. The six-month and four-year warrants expired unexercised in January 2010 and October 2013, respectively. | |
In August 2009, we entered into a private placement agreement under which we issued and sold (i) 730,994 shares of our common stock, (ii) six-month warrants to purchase up to 365,495 additional shares of common stock at an exercise price of $13.86 per share, and (iii) four-year warrants to purchase up to 328,946 additional shares of common stock at an exercise price of $15.00 per share, for $13.68 for each share sold generating gross proceeds of $10.0 million. The warrants were not exercisable for the first six months following the closing, which occurred on August 4, 2009. Subsequently, we filed, and the SEC declared effective, a registration statement covering the resale of the 730,994 shares of our common stock issued and the 694,441 shares issuable upon the exercise of the related warrants issued in this private placement. The six-month warrants expired unexercised in July 2010. | |
As part of all private placement agreements, we agreed to register the shares of common stock and the shares of common stock underlying the warrants (with the exception of the unit warrants from the January 2008 private placement) issued to the investors with the SEC within contractually specified time periods. As noted above, we filed registration statements covering all required shares. | |
During 2012, we terminated our then existing At Market Issuance Sales Agreement (the “Old ATM Program”) and entered into a new At Market Issuance Sales Agreement with MLV & Co. LLC, ("MLV") as sales agent, under which we may sell from time to time up to five million shares of our common stock (the “2012 ATM Program”). In December 2012, we entered into an Amended and Restated At Market Sales Issuance Agreement with MLV to increase the number of shares of common stock available for offer and sale under the 2012 ATM Program to an aggregate of ten million shares. | |
During the year ended December 31, 2012, we sold an aggregate of approximately 952,000 shares of our common stock in at the market offerings under the Old ATM Program and received net proceeds of approximately $2.8 million after deducting offering costs of approximately $87,000, and an aggregate of approximately 1.5 million shares of our common stock in at the market offerings under the 2012 ATM Program and received net proceeds of approximately $7.7 million after deducting offering costs of approximately $244,000. During the years ended December 31, 2014 and 2013, we sold an aggregate of approximately 215,000 and 4.8 million shares of our common stock in at the market offerings under the 2012 ATM Program and received net proceeds of approximately $601,000 and $17.0 million, respectively, after deducting offering costs of approximately $20,000 and $499,000, respectively. These offerings were made under effective shelf registration statements and proceeds from the offerings were used for general corporate purposes. | |
During September 2013, we sold approximately 3,333,000 shares of our common stock and warrants to purchase 1,000,000 shares of our common stock in a registered direct public offering raising net proceeds of approximately $9.5 million, after deducting offering expenses. The common stock and warrants were sold in units, with each unit consisting of one share of common stock and a warrant to purchase 0.3 of a share of common stock. Subject to certain ownership limitations, the warrants will become exercisable beginning 6 months following issuance and will expire five years from the date they become exercisable, at an exercise price of $3.75 per share. The number of shares issuable upon exercise of the warrants and the exercise price of the warrants are adjustable in the event of stock splits, stock dividends, combinations of shares and similar recapitalization transactions. | |
In February 2014, we issued and sold 22,236,000 shares of our common stock in a public underwritten offering. Net proceeds after deducting offering expenses were approximately $56.0 million. This offering was made under an effective shelf registration statement and proceeds from the offering are being used for general corporate purposes. | |
In February 2014, our Board of Directors retired 43,490 shares of our treasury stock then outstanding and returned those shares to authorized and unissued shares of our common stock. | |
In October 2014, we filed a Registration Statement on Form S-3, declared effective by the SEC on October 23, 2014 (the "2014 Registration Statement"), covering the offering of up to $150 million of common stock, preferred stock, warrants, debt securities and units. The 2014 Registration Statement included a prospectus covering the offering, issuance and sale of up to 10 million shares of our common stock from time to time in “at the market offerings” pursuant to an At Market Sales Issuance Agreement entered into with MLV on October 10, 2014. On October 10, 2014, we exercised our right under 2012 ATM Program to terminate the 2012 ATM Program upon effectiveness of the 2014 Registration Statement. |

Our 1999 Equity Incentive Plan, as amended (the "1999 EIP") authorized awards of incentive stock options within the meaning of Section 422 of the Internal Revenue Code (the “Code”), non-qualified stock options, nonvested (restricted) stock, and unrestricted stock for up to 2.0 million shares of common stock (subject to adjustment for stock splits and similar capital changes and exclusive of options exchanged at the consummation of mergers) to employees and, in the case of non-qualified stock options, nonvested (restricted) stock, and unrestricted stock, to consultants and directors as defined in the 1999 EIP. The plan terminated on November 15, 2009. On March 12, 2009, our Board of Directors adopted, and on June 10, 2009, our stockholders approved, our 2009 Equity Incentive Plan (the “2009 EIP”). The 2009 EIP provides for the grant of incentive stock options intended to qualify under Section 422 of the Code, nonstatutory stock options, restricted stock, unrestricted stock and other equity-based awards, such as stock appreciation rights, phantom stock awards, and restricted stock units, which we refer to collectively as Awards, for up to 4.2 million shares of our common stock (subject to adjustment in the event of stock splits and other similar events). On March 7, 2013, our Board of Directors adopted, and on June 12, 2013, our stockholders approved, an amendment to the 2009 EIP increasing shares available for award under the plan to 6.2 million. On February 26, 2014, our Board of Directors adopted, and on April 23, 2014, our stockholders approved, an amendment to the 2009 EIP increasing shares available for award under the plan to 10.2 million. The Board of Directors appointed the Compensation Committee to administer the 1999 EIP and the 2009 EIP. No awards will be granted under the 2009 EIP after June 10, 2019. | |||||||||||||
On March 12, 2009, our Board of Directors adopted, and on June 10, 2009, our stockholders approved, the 2009 Employee Stock Purchase Plan (the “2009 ESPP”) to provide eligible employees the opportunity to acquire our common stock in a program designed to comply with Section 423 of the Code. There are currently 166,666 shares of common stock reserved for issuance under the 2009 ESPP. Rights to purchase common stock under the 2009 ESPP are granted at the discretion of the Compensation Committee, which determines the frequency and duration of individual offerings under the plan and the dates when stock may be purchased. Eligible employees participate voluntarily and may withdraw from any offering at any time before the stock is purchased. Participation terminates automatically upon termination of employment. The purchase price per share of common stock in an offering is 85% of the lesser of its fair value at the beginning of the offering period or on the applicable exercise date and may be paid through payroll deductions, periodic lump sum payments, the delivery of our common stock, or a combination thereof. Unless otherwise permitted by the Board of Directors, no participant may acquire more than 3,333 shares of stock in any offering period. No participant is allowed to purchase shares under the 2009 ESPP if such employee would own or would be deemed to own stock possessing 5% or more of the total combined voting power or value of the Company. No offerings will be made under the 2009 ESPP after June 10, 2019. | |||||||||||||
Our Director’s Deferred Compensation Plan, as amended, permits each outside director to defer all, or a portion of, their cash compensation until their service as a director ends or until a specified date into a cash account or a stock account. There are 225,000 shares of our common stock reserved for issuance under this plan. As of December 31, 2014, 48,971 shares have been issued. Amounts deferred to a cash account will earn interest at the rate paid on one-year Treasury bills with interest added to the account annually. Amounts deferred to a stock account will be converted on a quarterly basis into a number of units representing shares of our common stock equal to the amount of compensation which the participant has elected to defer to the stock account divided by the applicable price for our common stock. The applicable price for our common stock has been defined as the average of the closing price of our common stock for all trading days during the calendar quarter preceding the conversion date as reported by The Nasdaq Capital Market. Pursuant to this plan, a total of 221,630 units, each representing a share of our common stock at a weighted average common stock price of $5.70, have been credited to participants’ stock accounts as of December 31, 2014. The compensation charges for this plan were immaterial for all periods presented. | |||||||||||||
We use the Black-Scholes option pricing model to value options granted to employees and non-employees, as well as options granted to members of our Board of Directors. All stock option grants have 10-year terms and generally vest ratably over a 3 or 4-year period. The non-cash charge to operations for the non-employee options with vesting or other performance criteria is affected each reporting period, until the non-employee options vest, by changes in the fair value of our common stock. | |||||||||||||
The fair value of each option granted during the periods was estimated on the date of grant using the following weighted average assumptions: | |||||||||||||
2014 | 2013 | 2012 | |||||||||||
Expected volatility | 84 | % | 87 | % | 96 | % | |||||||

Risk-free interest rate | 1.7 | % | 1.5 | % | 0.9 | % | |||||||
Dividend yield | — | % | — | % | — | % | |||||||
Expected volatility is based exclusively on historical volatility data of our common stock. The expected term of stock options granted is based on historical data and other factors and represents the period of time that stock options are expected to be outstanding prior to exercise. The risk-free interest rate is based on U.S. Treasury strips with maturities that match the expected term on the date of grant. | |||||||||||||

The aggregate intrinsic value in the table above represents the difference between our closing stock price on the last trading day of fiscal 2014 and the exercise price, multiplied by the number of in-the-money options that would have been received by the option holders had all option holders exercised their options on December 31, 2014 (the intrinsic value is considered to be zero if the exercise price is greater than the closing stock price). This amount changes based on the fair market value of our stock. The total intrinsic value of options exercised during the years ended December 31, 2014, 2013, and 2012, determined on the dates of exercise, was $45,000, $5,000, and $12,000, respectively. | |||||||||||||
During 2014, 2013, and 2012, all options were granted with exercise prices equal to the market value of the underlying shares of common stock on the grant date other than awards dated February 14, 2014. In February 2014, our Board of Directors approved awards subject to forfeiture in the event shareholder approval was not obtained to increase the shares available under our 2009 EIP. This approval was obtained in April 2014. Accordingly, these awards have a grant date of April 2014 with an exercise price as of the date the Board of Director's approved the awards in February 2014. | |||||||||||||
As of December 31, 2014, there was $4.4 million of total unrecognized compensation cost related to stock options granted to employees and directors expected to be recognized over a weighted average period of 2.2 years. | |||||||||||||
As of December 31, 2014, unrecognized expense for options granted to outside advisors for which performance (vesting) has not yet been completed but the exercise price of the option is known is $314,000. Such amount is subject to change each reporting period based upon changes in the fair value of our common stock, expected volatility, and the risk-free interest rate, until the outside advisor completes his or her performance under the option agreement. | |||||||||||||

License, Research, and Other Agreements | License, Research, and Other Agreements |
In May 2001, we entered into a license agreement with UConn which was amended in March 2003 and June 2009. Through the license agreement, we obtained an exclusive license to patent rights resulting from inventions discovered under a research agreement that was effective from February 1998 until December 2006. The term of the license agreement ends when the last of the licensed patents expires (2024) or becomes no longer valid. UConn may terminate the agreement: (1) if, after 30 days written notice for breach, we continue to fail to make any payments due under the license agreement, or (2) we cease to carry on our business related to the patent rights or if we initiate or conduct actions in order to declare bankruptcy. We may terminate the agreement upon 90 days written notice. We are still required to make royalty payments on any obligations created prior to the effective date of termination of the license agreement. Upon expiration or termination of the license agreement due to breach, we have the right to continue to manufacture and sell products covered under the license agreement which are considered to be works in progress for a period of 6 months. The license agreement contains aggregate milestone payments of $1.2 million for each product we develop covered by the licensed patent rights. These milestone payments are contingent upon regulatory filings, regulatory approvals and commercial sales of products. We have also agreed to pay UConn a royalty on the net sales of products covered by the license agreement as well as annual license maintenance fees beginning in May 2006. Royalties otherwise due on the net sales of products covered by the license agreement may be credited against the annual license maintenance fee obligations. As of December 31, 2014, we have paid $640,000 to UConn under the license agreement. The license agreement gives us complete discretion over the commercialization of products covered by the licensed patent rights, but also requires us to use commercially reasonable diligent efforts to introduce commercial products within and outside the United States. If we fail to meet these diligence requirements, UConn may be able to terminate the license agreement. | |
In March 2003, we entered into an amendment agreement that amended certain provisions of the license agreement with UConn. The amendment agreement granted us a license to additional patent rights. In consideration for execution of the amendment agreement, we agreed to pay UConn an upfront payment and to make future payments for licensed patents or patent applications. Through December 31, 2014, we have paid approximately $100,000 to UConn under the license agreement, as amended. | |
In December 2011, we signed a license, development and manufacturing technology transfer agreement (“NewVac Agreement”) for Oncophage with NewVac LLC (a subsidiary of ChemRar Ventures LLC, “NewVac”), a company focused on the development of innovative technology for cancer immunotherapy. Under the NewVac Agreement, we granted NewVac an exclusive license to manufacture, market and sell Oncophage as well as pursue a development program in the Russian Federation and certain other CIS countries. The NewVac Agreement had an initial term of three years and could have been extended under certain terms for a period ending the later of December 2021, or the expiration of the last valid claim of the licensed patent rights, as defined. During the term of the NewVac Agreement we were entitled to receive modest milestone payments in addition to payments for supply of Oncophage and/or royalties in the low double-digits on net sales of Oncophage. Upon termination of the NewVac Agreement, all activity under the agreement immediately ceases. In December 2014, the NewVac Agreement expired in accordance with its terms. | |
On December 5, 2014, we entered into a license agreement with the Ludwig Institute for Cancer Research Ltd. (“Ludwig”), which replaced and superseded the Collaborative Research and Development Agreement entered into on May 23, 2011 (the “Prior Agreement”). Pursuant to the terms of the license agreement, Ludwig granted us an exclusive, worldwide license under certain intellectual property rights of Ludwig and Memorial Sloan Kettering Cancer Center arising from the Prior Agreement, to further develop and commercialize GITR, OX40 and TIM-3 antibodies. Pursuant to the license agreement, we made an upfront payment of $1.0 million to Ludwig. The license agreement also obligates us to make potential milestone payments of up to $20.0 million for events prior to regulatory approval of licensed products, and potential milestone payments in excess of $80.0 million if licensed products are approved in multiple jurisdictions, in more than one indication, and certain sales milestones are achieved. We will also be obligated to pay low to mid-single digit royalties on all net sales of licensed products during the royalty period, and to pay Ludwig a percentage of any sublicensing income, ranging from a low to mid-double digit percentage depending on various factors. The license agreement may be terminated as follows: (i) by either party if the other party commits a material, uncured breach; (ii) by either party if the other party initiates bankruptcy, liquidation or similar proceedings; or (iii) by us for convenience upon 90 days’ prior written notice. The license agreement also contains customary representations and warranties, mutual indemnification, confidentiality and arbitration provisions. | |
We have entered into various agreements with institutions and contract research organizations to conduct clinical studies. Under these agreements, subject to the enrollment of patients and performance by the institution of certain services, we have estimated our payments to be $53.5 million over the term of the studies. For the years ended December 31, 2014, 2013, and 2012, $895,000, $2,720,000, and $654,000, respectively, have been expensed in the accompanying consolidated statements of operations related to these clinical studies. Through December 31, 2014, $51.1 million of this estimate has been paid. The timing of our expense recognition and future payments related to these agreements is dependent on the enrollment of patients and documentation received from the institutions. | |
We have various comprehensive agreements with collaborative partners that allow for the use of QS-21 Stimulon, an investigational adjuvant used in numerous vaccines under development for a variety of diseases including, but not limited to, hepatitis, HIV, influenza, cancer, Alzheimer’s disease, malaria, and tuberculosis. These agreements grant exclusive worldwide rights in some fields of use, and co-exclusive or non-exclusive rights in others. The agreements call for royalties to be paid to us by the collaborative partner on the future sales of licensed vaccines that include QS-21 Stimulon. | |
In July 2006, we entered into a license agreement and a supply agreement with GlaxoSmithKline ("GSK") for the use of QS-21 Stimulon (the "GSK License Agreement" and the "GSK Supply Agreement", respectively). In January 2009, we entered into an Amended and Restated Manufacturing Technology Transfer and Supply Agreement (the “Amended GSK Supply Agreement”) under which GSK has the right to manufacture all of its requirements of commercial grade QS-21 Stimulon. GSK is obligated to supply us (or our affiliates, licensees, or customers) certain quantities of commercial grade QS-21 Stimulon for a stated period of time. In March 2012 we entered into a First Right to Negotiate and Amendment Agreement amending the GSK License Agreement and the Amended GSK Supply Agreement to clarify and include additional rights for the use of QS-21 Stimulon (the "GSK First Right to Negotiate Agreement"). In addition, we granted GSK the first right to negotiate for the purchase of the Company or certain of our assets. The first right to negotiate will expire after five years. As consideration for entering into the GSK First Right to Negotiate Agreement, GSK paid us an upfront, non-refundable payment of $9.0 million, $2.5 million of which is creditable toward future royalty payments. We sometimes refer to the GSK License Agreement, the Amended GSK Supply Agreement and the GSK First Right to Negotiate Agreement, the "GSK Agreements". As of December 31, 2014, we have received $23.3 million of a potential $24.3 million in upfront and milestone payments related to the GSK Agreements. We are generally entitled to receive low single-digit royalties on net sales for a period of 7-10 years after the first commercial sale of a resulting GSK product. The GSK License and Amended GSK Supply Agreements may be terminated by either party upon a material breach if the breach is not cured within the time specified in the respective agreement. The termination or expiration of the GSK License Agreement does not relieve either party from any obligation which accrued prior to the termination or expiration. Among other provisions, the milestone payment obligations survive termination or expiration of the GSK Agreements for any reason, and the license rights granted to GSK survive expiration of the GSK License Agreement. The license rights and payment obligations of GSK under the Amended GSK Supply Agreement survive termination or expiration, except that GSK's license rights and future royalty obligations do not survive if we terminate due to GSK's material breach unless we elect otherwise. | |
During the years ended December 31, 2014, 2013, and 2012, we recognized revenue of $3.3 million, $1.3 million, and $1.3 million, respectively, related to payments received under our GSK License and Amended GSK Supply Agreements. As we have no future service obligation under the GSK First Right to Negotiate Agreement, we recognized $6.5 million in revenue during the year ended December 31, 2012. Deferred revenue of $2.5 million related to the GSK Agreements is included in deferred revenue on our consolidated balance sheet as of December 31, 2014. | |
During March 2012, we received $6.25 million through an amended license of non-core technologies with an existing licensee. This amendment converted the license grant from non-exclusive to exclusive and enabled the licensee to buy-out the current royalty stream structure. As we have no future service obligation under this agreement, we recognized the $6.25 million in revenue during the year ended December 31, 2012. |

As of December 31, 2014, we have $6.3 million in principal of debt outstanding: $6.1 million of notes and $146,000 of debentures. | |
Convertible Notes—2006 Notes | |
On October 30, 2006 (the “Issuance Date”), we issued $25.0 million of the 2006 Notes to a group of accredited investors (“Investors”). These 2006 Notes bore interest at 8% (an effective rate of 8.10%) payable semi-annually on December 30 and June 30 in cash or, at our option, in additional notes or a combination thereof and had an original maturity date of August 30, 2011. During the years ended December 2012, we issued additional 2006 Notes in the amount of $1.5 million as payment for interest due. | |
On February 23, 2011, we entered into a Ninth Amendment of Rights Agreement (the “Amendment”) to the 2006 Notes. The Amendment extended the maturity date of the 2006 Notes to August 31, 2014, and waived the rights of the note holders to convert the 2006 Notes into our common stock. | |
On April 15, 2013, we entered into a Securities Exchange Agreement (the “Exchange”) with the holders of all of our 2006 Notes which were due August 2014 (outstanding principal of $39.0 million). The holders exchanged the 2006 Notes, including all accrued interest thereon, for $10.0 million in cash, 2,500,000 shares of our common stock (for purpose of the Exchange, valued at $4.51 per share) (the “Shares”), and a contractual right to the proceeds of 20% of our revenue interests from certain QS-21 Stimulon partnered programs and a 0.5% royalty on net sales of HerpV. The rights are governed by a Revenue Interests Assignment Agreement dated as of April 15, 2013 between us and the holders of the 2006 Notes. The rights were valued at $19.1 million on April 15, 2013, ($15.3 million and $18.8 million at December 31, 2014 and December 31, 2013 respectively) based on management's estimate with the assistance of a third party valuation and are reflected in the consolidated balance sheet as contingent royalty obligation. For the year ended December 31, 2013 we recorded a loss of $3.3 million in non-operating (loss) income based on the Exchange and eliminated $5.6 million of non-controlling interest. | |
Notes—2013 Notes | |
In connection with the Exchange, we entered into a Loan and Security Agreement with Silicon Valley Bank for senior secured debt in the aggregate principal amount of $5.0 million (the “SVB Loan”). The SVB Loan bears interest at a rate of 6.75% per annum, payable in cash on the first day of each month. Principal payments of approximately $278,000 are due monthly beginning November 2013 and ending in April 2015. As of December 31, 2014, $1.1 million remains outstanding on the SVB Loan. The SVB Loan is secured by a lien against substantially all of our assets and contains a number of restrictions and covenants, including, but not limited to, restrictions and covenants that limit our ability to incur certain additional indebtedness, make certain investments, pay dividends other than dividends required pursuant to pre-existing commitments, make payments on subordinated indebtedness other than regularly scheduled payments of interest, create certain liens, consolidate, merge, sell or otherwise dispose of our assets, and/or change our line of business. The SVB Loan also specifies a number of events of default (some of which are subject to applicable cure periods), including, among other things, covenant defaults, other non-payment defaults, bankruptcy, certain penalties and judgments from a governmental authority, cross-defaults in respect of indebtedness over $50,000, and insolvency defaults. | |
Additionally, any material adverse change with respect to us or our subsidiary, Antigenics Inc., constitutes an event of default. Upon the occurrence of an event of default under the SVB Loan, subject to cure periods in certain circumstances, Silicon Valley Bank may declare all amounts outstanding to be immediately due and payable and may foreclose upon our assets that secure the SVB Loan. During the continuance of an event of default which does not accelerate the maturity of the SVB Loan, interest will accrue at a default rate equal to the otherwise applicable rate plus 5%. We may prepay the SVB Loan at any time, in full, subject to certain notice requirements and a prepayment premium equal to 4% of the outstanding principal amount of the SVB Loan. | |
In addition, in connection with the Exchange, we also entered into a Note Purchase Agreement, dated as of April 15, 2013 with various investors to issue senior subordinated notes (the “2013 Subordinated Notes”) in the aggregate principal amount of $5.0 million and four year warrants to purchase 500,000 unregistered shares of our common stock at an exercise price of $4.41 per share. We recorded a debt discount of $1.1 million based on the relative fair values of the 2013 Subordinated Notes and 4 year warrants. The 2013 Subordinated Notes bear interest at a rate of 10% per annum, payable in cash on the first day of each month in arrears and were due April 2015. The 2013 Subordinated Notes include default provisions which allow for the acceleration of the principal payment of the 2013 Subordinated Notes in the event we become involved in certain bankruptcy proceedings, become insolvent, fail to make a payment of principal or (after a grace period) interest on the 2013 Subordinated Notes, default on other indebtedness with an aggregate principal balance of $5.0 million or more if such default has the effect of accelerating the maturity of such indebtedness, or become subject to a legal judgment or similar order for the payment of money in an amount greater than $5.0 million if such amount will not be covered by third-party insurance. The debt discount, and issuance costs of approximately $178,000, are being amortized using the effective interest method over 2 years, the expected life of the SVB Loan and the 2013 Subordinated Notes. During February 2015, we exchanged the 2013 Subordinated Notes, see Note 20 for further discussion. As a result of this exchange, the 2013 Subordinated Notes outstanding as of December 31, 2014 are classified as long-term within our consolidated balance sheets. | |

At December 31, 2014, approximately $146,000 of debentures we assumed in our merger with Aquila Biopharmaceuticals are outstanding. These debentures carry interest at 7% and are callable by the holders. Accordingly they are classified as part of our long-term debt. |
Fair_Value_Measurements
Fair Value Measurements | 12 Months Ended | ||||||||||||||||
Dec. 31, 2013 | |||||||||||||||||
Fair Value Measurements [Abstract] | |||||||||||||||||
Fair Value Measurements | Fair Value Measurements | ||||||||||||||||
We measure fair value based on a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. The fair value hierarchy is broken down into three levels based on the source of inputs as follows: | |||||||||||||||||
Level 1-Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access; | |||||||||||||||||
Level 2-Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly; and | |||||||||||||||||
Level 3-Valuations based on inputs that are unobservable and significant to the overall fair value measurement. | |||||||||||||||||
The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level input that is significant to the overall fair value measurement. | |||||||||||||||||
The estimated fair values of all of our financial instruments, excluding long-term debt, approximate their carrying amounts in the consolidated balance sheets. The fair value of our long-term debt was derived by evaluating the nature and terms of each note and considering the prevailing economic and market conditions at the balance sheet date. | |||||||||||||||||
We measure our contingent royalty obligation and our contingent purchase price at fair value. The fair values of our contingent royalty obligation and contingent purchase price, $15.3 million and $16.4 million respectively at December 31, 2014, are based on significant inputs not observable in the market, which require it to be reported as a Level 3 liability within the fair value hierarchy. The valuations use assumptions we believe would be made by a market participant. In particular, the valuation analysis for the contingent royalty obligation used the Income Approach based on the sum of the economic income that an asset is anticipated to produce in the future. In this case that asset is the potential royalty income to be paid to us as a result of certain license agreements for QS-21 Stimulon and the potential net sales generated from HerpV. The fair value of the contingent royalty obligation is estimated by applying a risk adjusted discount rate (10.2%) to the probability adjusted royalty revenue stream based on expected approval dates. These fair value estimates are most sensitive to changes in the probability of regulatory approvals. The Discounted Cash Flow method of the Income Approach was chosen as the method best suited to valuing the contingent royalty obligation. | |||||||||||||||||
The fair value of our contingent purchase price consideration is based on estimates from a Monte Carlo simulation of our market capitalization and other factors impacting the probability of triggering the milestone payments. Market capitalization was evolved using a geometric brownian motion, calculated daily for the life of the contingent purchase price consideration. | |||||||||||||||||

Subsequent Events [Abstract] | |
Subsequent Events | Subsequent Events |
On January 9, 2015, we entered into a global license, development and commercialization agreement (the “Collaboration Agreement”) with Incyte Corporation ("Incyte") and a wholly-owned subsidiary thereof, pursuant to which the parties agreed to develop and commercialize novel immuno-therapeutics using Agenus’ proprietary Retrocyte DisplayTM antibody discovery platform. | |
Pursuant to the terms of the Collaboration Agreement, Incyte paid upfront payments to us totaling $25.0 million in February 2015. The collaboration will initially focus on four checkpoint modulator programs directed at GITR, OX40, LAG-3 and TIM-3. The parties will share all costs and profits for the GITR and OX40 antibody programs on a 50:50 basis, and we will be eligible to receive potential milestone payments for these two antibody programs. Incyte is obligated to reimburse us for all development costs that we incur in connection with the LAG-3 and TIM-3 antibody programs, and we will be eligible to receive potential milestone payments and royalties. Through the direction of a joint steering committee, the parties anticipate that, for each program, we will lead preclinical development activities through IND filing, and Incyte will lead all clinical development activities. The parties expect to initiate the first clinical trials of antibodies arising from these programs in 2016. The Collaboration Agreement became effective February 19, 2015. | |
On January 9, 2015, we also entered into a Stock Purchase Agreement with Incyte (the “Stock Purchase Agreement” and together with the Collaboration Agreement, the “Agreements”), pursuant to which Incyte purchased approximately 7.76 million shares of our common stock (the “Shares”) in February 2015 for an aggregate purchase price of $35.0 million, or approximately $4.51 per share. Incyte owns approximately 11% of the outstanding shares of our common stock after such purchase. Under the Stock Purchase Agreement, Incyte has agreed not to dispose of any of the Shares for a period of 12 months and we have agreed to register the Shares for resale under the Securities Act of 1933, as amended (the “Securities Act”). | |
On January 23, 2015, we achieved the first contingent milestone pursuant to the terms of our Share Exchange Agreement with the 4-AB Shareholders and accordingly are obligated to pay $20.0 million to such 4-AB Shareholders. | |
On February 20, 2015, the Company, certain existing investors and certain additional investors entered into an Amended and Restated Note Purchase Agreement, pursuant to which we (i) canceled the 2013 Subordinated Notes in exchange for new senior subordinated promissory notes (the “2015 Subordinated Notes”) in the aggregate principal amount of $5.0 million, (ii) issued additional 2015 Subordinated Notes in the aggregate principal amount of $9.0 million and (iii) issued five year warrants to purchase 1,400,000 shares of our common stock at an exercise price of $5.10 per share. | |
The 2015 Subordinated Notes bear interest at a rate of 8% per annum, payable in cash on the first day of each month in arrears. Among other default and acceleration terms customary for indebtedness of this type, the 2015 Subordinated Notes include default provisions which allow for the acceleration of the principal payment of the 2015 Subordinated Notes in the event we become involved in certain bankruptcy proceedings, become insolvent, fail to make a payment of principal or (after a grace period) interest on the 2015 Subordinated Notes, default on other indebtedness with an aggregate principal balance of $13.5 million or more if such default has the effect of accelerating the maturity of such indebtedness, or become subject to a legal judgment or similar order for the payment of money in an amount greater than $13.5 million if such amount will not be covered by third-party insurance. The 2015 Subordinated Notes are not convertible and will mature on February 20, 2018, at which point the we must repay the outstanding balance in cash. The Company may prepay the 2015 Subordinated Notes at any time, in part or in full, without premium or penalty. |

Summary of Significant Accounting Policies (Policies) | 12 Months Ended | |||||||||
Dec. 31, 2014 | ||||||||||
Accounting Policies [Abstract] | ||||||||||
Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation | |||||||||
The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles and include the accounts of Agenus and our wholly-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated in consolidation. | ||||||||||
Segment Information | Segment Information | |||||||||
We are managed and operated as one business. The entire business is managed by a single executive operating committee that reports to the chief executive officer. We do not operate separate lines of business with respect to any of our product candidates. Accordingly, we do not prepare discrete financial information with respect to separate product areas or by location and do not have separately reportable segments as defined by Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 280, Segment Reporting. | ||||||||||
Use of Estimates | Use of Estimates | |||||||||
The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. We base those estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates. | ||||||||||
Cash and Cash Equivalents | Cash and Cash Equivalents | |||||||||
We consider all highly liquid investments purchased with maturities at acquisition of three months or less to be cash equivalents. Cash equivalents consist primarily of money market funds. | ||||||||||
Investments | Investments | |||||||||
We classify investments in marketable securities at the time of purchase. At December 31, 2014, all marketable securities are classified as available for sale and as such, the investments are recorded at fair value. Gains and losses on the sale of marketable securities are recognized in operations based on the specific identification method. At December 31, 2014, our investments consisted of institutional money market funds and U.S. treasury bills. | ||||||||||
Concentration Risk Disclosure [Text Block] | Concentrations of Credit Risk | |||||||||
Financial instruments that potentially subject us to concentrations of credit risk are primarily cash equivalents, investments, and accounts receivable. We invest our cash, cash equivalents and short-term investments in accordance with our investment policy, which specifies high credit quality standards and limits the amount of credit exposure from any single issue, issuer, or type of investment. We carry balances in excess of federally insured levels, however, we have not experienced any losses to date from this practice. | ||||||||||
Inventories | Inventories | |||||||||
Inventories are stated at the lower of cost or market. Cost has been determined using standard costs that approximate the first-in, first-out method. Inventory as of December 31, 2014 consisted solely of finished goods. | ||||||||||
Property, Plant and Equipment Disclosure [Text Block] | Plant and Equipment | |||||||||
Plant and equipment, including software developed for internal use, are carried at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Amortization of leasehold improvements is computed over the shorter of the lease term or estimated useful life of the asset. Additions and improvements are capitalized, while repairs and maintenance are charged to expense as incurred. Amortization and depreciation of plant and equipment was $1.1 million, $586,000, and $1.6 million, for the years ended December 31, 2014, 2013, and 2012, respectively. | ||||||||||
Plant and Equipment | ||||||||||
Plant and equipment as of December 31, 2014 and 2013 consists of the following (in thousands): | ||||||||||

Fair Value of Financial Instruments | Fair Value of Financial Instruments | |||||||||
The estimated fair values of all of our financial instruments, excluding debt, approximate their carrying amounts in the consolidated balance sheets. The fair value of our outstanding debt is based on a present value methodology. The outstanding principal amount of our debt, including the current portion, was $6.3 million and $9.6 million at December 31, 2014 and 2013, respectively. | ||||||||||
Revenue Recognition | Revenue Recognition | |||||||||
Revenue for services under research and development contracts are recognized as the services are performed, or as clinical trial materials are provided. Non-refundable milestone payments that represent the completion of a separate earnings process are recognized as revenue when earned. License fees and royalties are recognized as they are earned. Grant revenue is recognized when the associate expense is recorded. Revenue recognized from collaborative agreements is based upon the provisions of ASC 605-25, Revenue Recognition – Multiple-Element Arrangements, as amended by Accounting Standards Update 2009-13. For the years ended December 31, 2014, 2013, and 2012, 48%, 44%, and 49%, respectively, of our revenue was earned from one research partner. In addition, 40% of our revenue for the year December 31, 2012, was earned from one of our licensees and 47% and 9%, of our revenue for the years ended December 31, 2013 and 2012, respectively, was earned from one service customer. The revenues from the licensee did not continue past 2012 and the revenue from the service customer did not continue past 2013. | ||||||||||
Foreign Currency Transactions | Foreign Currency Transactions | |||||||||
Gains and losses from our foreign currency based accounts and transactions, such as those resulting from the translation and settlement of receivables and payables denominated in foreign currencies, are included in the consolidated statements of operations within other income (expense). We do not currently use derivative financial instruments to manage the risks associated with foreign currency fluctuations. We recorded foreign currency losses of $773,000, $9,000, and $11,000, for the years ended December 31, 2014, 2013, and 2012, respectively. | ||||||||||
Research and Development | Research and Development | |||||||||
Research and development expenses include the costs associated with our internal research and development activities, including salaries and benefits, share-based compensation, occupancy costs, clinical manufacturing costs, related administrative costs, and research and development conducted for us by outside advisors, such as sponsored university-based research partners and clinical study partners. We account for our clinical study costs by estimating the total cost to treat a patient in each clinical trial and recognizing this cost based on estimates of when the patient receives treatment, beginning when the patient enrolls in the trial. Research and development expenses also include the cost of clinical trial materials shipped to our research partners. Research and development costs are expensed as incurred. | ||||||||||
Share-based Compensation | Share-Based Compensation | |||||||||
We account for share-based compensation in accordance with the provisions of ASC 718, Compensation—Stock Compensation and ASC 505-50, Equity-Based Payments to Non-Employees. Share-based compensation expense is recognized based on the estimated grant date fair value, and is recognized net of an estimated forfeiture rate such that we recognize compensation cost for those shares expected to vest. Compensation cost is recognized on a straight-line basis over the requisite service period of the award. The non-cash charge to operations for non-employee options with vesting or other performance criteria is affected each reporting period by changes in the fair value of our common stock. Under the provisions of ASC 505-50, the change in fair value of vested options issued to non-employees is reflected in the statement of operations each reporting period, until the options are exercised or expire. See Note 10 for a further discussion on share-based compensation. | ||||||||||
Income Taxes | Income Taxes | |||||||||
Income taxes are accounted for under the asset and liability method with deferred tax assets and liabilities recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which such items are expected to be reversed or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the consolidated statement of operations in the period that includes the enactment date. Deferred tax assets are recorded when they more likely than not are expected to be realized. | ||||||||||
Earnings Per Share [Text Block] | Net Loss Per Share | |||||||||
Basic income and loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding (including common shares issuable under our Directors’ Deferred Compensation Plan). Diluted income per common share is calculated by dividing net income attributable to common stockholders by the weighted average number of common shares outstanding (including common shares issuable under our Directors’ Deferred Compensation Plan) plus the dilutive effect of outstanding instruments such as warrants, stock options, nonvested shares, convertible preferred stock, and convertible notes. Because we reported a net loss attributable to common stockholders for all periods presented, diluted loss per common share is the same as basic loss per common share, as the effect of utilizing the fully diluted share count would have reduced the net loss per common share. Therefore, the following potentially dilutive securities have been excluded from the computation of diluted weighted average shares outstanding as of December 31, 2014, 2013, and 2012, as they would be anti-dilutive: | ||||||||||
At December 31, | ||||||||||
2014 | 2013 | 2012 | ||||||||
Warrants | 2,951,450 | 3,280,396 | 3,309,378 | |||||||
Stock options | 6,525,724 | 4,163,100 | 2,748,883 | |||||||
Nonvested shares | 78,828 | 147,274 | 249,968 | |||||||
Convertible preferred stock | 333,333 | 333,333 | 333,333 | |||||||
Goodwill | Goodwill | |||||||||
Goodwill represents the excess of cost over the fair value of net assets of businesses acquired. Goodwill is not amortized, but instead tested for impairment at least annually. Annually we assess whether there is an indication that goodwill is impaired, or more frequently if events and circumstances indicate that the asset might be impaired during the year. We perform our annual impairment test as of October 31 of each year. The first step of our impairment analysis compares our fair value to our net book value to determine if there is an indicator of impairment. We operate as a single operating segment and single reporting unit and our fair value is based on our quoted market price of our common stock to derive the market capitalization as of the date of the impairment test. ASC 350, Intangibles, Goodwill and Other states that if the carrying value of the reporting unit is negative, the second step of the impairment test shall be performed to measure the amount of impairment loss, if any, if qualitative factors indicate that it is more likely than not that a goodwill impairment exists. | ||||||||||
In Process Research and Development, Policy [Policy Text Block] | In-process Research and Development | |||||||||
Acquired in-process research and development ("IPR&D") represents the fair value assigned to research and development assets that have not reached technological feasibility. The value assigned to acquired IPR&D is determined by estimating the costs to develop the acquired technology into commercially viable products, estimating the resulting revenue from the projects, and discounting the net cash flows to present value. The revenue and costs projections used to value acquired IPR&D are, as applicable, reduced based on the probability of success of developing a new drug. Additionally, the projections consider the relevant market sizes and growth factors, expected trends in technology, and the nature and expected timing of new product introductions by us and our competitors. The rates utilized to discount the net cash flows to their present value are commensurate with the stage of development of the projects and uncertainties in the economic estimates used in the projections. Upon the acquisition of IPR&D, we complete an assessment of whether our acquisition constitutes the purchase of a single asset or a group of assets. We consider multiple factors in this assessment, including the nature of the technology acquired, the presence or absence of separate cash flows, the development process and stage of completion, quantitative significance and our rationale for entering into the transaction. | ||||||||||
If we acquire an asset or group of assets that do not meet the definition of a business under applicable accounting standards, then the acquired IPR&D is expensed on its acquisition date. Future costs to develop these assets are recorded to research and development expense as they are incurred. | ||||||||||
We review amounts capitalized as acquired IPR&D for impairment at least annually, as of October 31, and whenever events or changes in circumstances indicate that the carrying value of the assets might not be recoverable. When performing our impairment assessment, we have the option to first assess qualitative factors to determine whether it is necessary to recalculate the fair value of our acquired IPR&D. If we elect this option and believe, as a result of the qualitative assessment, that it is more-likely-than-not that the fair value of our acquired IPR&D is less than its carrying amount, we calculate the fair value using the same methodology as described above. If the carrying value of our acquired IPR&D exceeds its fair value, then the intangible asset is written-down to its fair value. Alternatively, we may elect to not first assess qualitative factors and immediately recalculate the fair value of our acquired IPR&D. No IPR&D impairments were recognized for the years presented. | ||||||||||
Accounting for Asset Retirement Obligations | Accounting for Asset Retirement Obligations | |||||||||
We record the fair value of an asset retirement obligation as a liability in the period in which we incur a legal obligation associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development, and/or normal use of the assets. A legal obligation is a liability that a party is required to settle as a result of an existing or enacted law, statute, ordinance, or contract. We are also required to record a corresponding asset that is depreciated over the life of the asset. Subsequent to the initial measurement of the asset retirement obligation, the obligation will be adjusted at the end of each period to reflect the passage of time (accretion) and changes in the estimated future cash flows underlying the obligation. Changes in the liability due to accretion are charged to the consolidated statement of operations, whereas changes due to the timing or amount of cash flows are an adjustment to the carrying amount of the related asset. Our asset retirement obligations primarily relate to the expiration of our facility lease and anticipated costs to be incurred based on our lease terms. | ||||||||||
Long-lived Assets | Long-lived Assets | |||||||||
If required based on certain events and circumstances, recoverability of assets to be held and used, other than goodwill and intangible assets not being amortized, is measured by a comparison of the carrying amount of an asset to the undiscounted future net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Authoritative guidance requires companies to separately report discontinued operations and extends that reporting to a component of an entity that either has been disposed of (by sale, abandonment, or in a distribution to owners) or is classified as held for sale. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. | ||||||||||
Description of New Accounting Pronouncements Not yet Adopted [Text Block] | Recent Accounting Pronouncements | |||||||||
In July 2013, the FASB issued Accounting Standards Update No. 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists", ("ASU 2013-11"). ASU 2013-11 amends ASC 740, "Income Taxes", by providing guidance on the financial statement presentation of an unrecognized benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 does not affect the recognition or measurement of uncertain tax positions under ASC 740. ASU 2013-11 is effective for interim and annual periods beginning after December 15, 2013, with early adoption permitted. The adoption of ASU 2013-11 did not have an impact on our consolidated financial statements. | ||||||||||
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, ("ASU 2014-09"). ASU 2014-09 amends revenue recognition principles and provides a single set of criteria for revenue recognition among all industries. This new standard provides a five step framework whereby revenue is recognized when promised goods or services are transferred to a customer at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires enhanced disclosures pertaining to revenue recognition in both interim and annual periods. ASU 2014-09 is effective for interim and annual periods beginning after December 15, 2016. We are currently evaluating the potential impact that ASU 2014-09 may have on our consolidated financial statements and related disclosures. | ||||||||||
In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern, ("ASU 2014-15"). ASU 2014-15 describes how an entity should assess its ability to meet obligations and sets rules for how this information should be disclosed in the financial statements. The standard provides guidance that will be used along with existing auditing standards. ASU 2014-15 applies to all entities and is effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter with early adoption permitted. We are currently evaluating the potential impact that ASU 2014-15 may have on our consolidated financial statements and related disclosures. |
