Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies The Company's significant accounting policies are described in note 2 of the notes to the consolidated financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2013 as filed with the Securities and Exchange Commission (SEC). Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying financial statements include all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation of the Company's financial position, results of operations, and cash flows for the periods presented. The consolidated financial statements include the accounts of the Company and its wholly owned and majority owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The Company records net income (loss) attributable to non-controlling interest in the Company's consolidated financial statements equal to the percentage of ownership interest retained in the respective operations by the non-controlling parties. The Company has no unconsolidated subsidiaries or significant investments accounted for under the equity method. The Company's results of operations for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected from the Company for the entire fiscal year or any other quarter of the fiscal year ending December 31, 2014. These consolidated financial statements should be read in conjunction with the Company's audited financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2013 as filed with the SEC. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs, expenses and accumulated other comprehensive loss that are reported in the consolidated financial statements and accompanying disclosures. Actual results may be different. Contingencies The Company may be, from time to time, a party to various disputes and claims arising from normal business activities. The Company continually assesses litigation to determine if an unfavorable outcome would lead to a probable loss or reasonably possible loss which could be estimated. In accordance with the guidance of the Financial Accounting Standards Board (FASB) on accounting for contingencies, the Company accrues for all contingencies at the earliest date at which the Company deems it probable that a liability has been incurred and the amount of such liability can be reasonably estimated. If the estimate of a probable loss is a range and no amount within the range is more likely than another, the Company accrues the minimum of the range. In the cases where the Company believes that a reasonably possible loss exists, the Company discloses the facts and circumstances of the litigation, including an estimable range, if possible. Revenue Recognition The Company's revenue recognition accounting policy is described in note 2 of the notes to the consolidated financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2013 as filed with the SEC. Effective with the first quarter of 2014, the Company has modified its revenue recognition accounting policy with respect to product sales of Cleviprex and ready-to-use Argatroban as follows: Product Sales of Cleviprex and Ready-to-Use Argatroban. Prior to January 1, 2014, product sales from Cleviprex and ready-to-use Argatroban were recorded under a deferred revenue model as the Company did not have sufficient information to develop reasonable estimates of expected returns and other adjustments to gross revenue. Under the deferred revenue model, the Company did not recognize revenue upon product shipment to Integrated Commercialization Solutions (ICS). Instead, upon product shipment, the Company invoiced ICS, recorded deferred revenue at gross invoice sales price, classified the cost basis of the product held by ICS as finished goods inventory held by others and included such cost basis amount within prepaid expenses and other current assets on the consolidated balance sheets. The Company recognized revenue when hospitals purchased the products. Beginning in 2014, the Company is recognizing revenue for Cleviprex and ready-to-use Argatroban as product is sold to ICS in the same manner as it recognizes Angiomax and Recothrom revenue, as the Company believes there is now sufficient history to reasonably estimate expected returns and other adjustments to revenue. During 2014 the Company recognized one-time increases of $0.7 million in net sales of Cleviprex and $1.6 million in net sales of ready-to-use Argatroban, representing product sales previously deferred as of December 31, 2013, net of chargebacks and other discounts or accruals for product returns, rebates and fee-for-service charges. Research and Development Research and development costs are expensed as incurred. Clinical study costs are accrued over the service periods specified in the contracts and adjusted as necessary based upon an ongoing review of the level of effort and costs actually incurred. Payments for a product license prior to regulatory approval of the product and payments for milestones achieved prior to regulatory approval of the product are expensed in the period incurred as research and development. Milestone payments made in connection with regulatory approvals are capitalized and amortized to cost of revenue over the remaining useful life of the asset. The Company performs research and development for U.S. government agencies under a cost-reimbursable contract in which the Company is reimbursed for direct costs incurred plus allowable indirect costs. The Company recognizes the reimbursements under research contracts when a contract has been executed, the contract price is fixed and determinable, delivery of services or products has occurred and collection of the contract price is reasonably assured. The reimbursements are classified as an offset to research and development expenses. Payments received in advance of work performed are deferred. For the three months ended June 30, 2014 and six months ended June 30, 2014, the Company recorded approximately $3.4 million of reimbursements by the government as a reduction of research and development expenses. Share-Based Compensation The Company accounts for share-based compensation in accordance with FASB Accounting Standards Codification (ASC) 718-10 (ASC 718-10), and recognizes expense using the accelerated expense attribution method. ASC 718-10 requires companies to recognize compensation expense in an amount equal to the fair value of all share-based awards granted to employees. The Company estimates the fair value of its options on the date of grant using the Black-Scholes closed-form option-pricing model. Expected volatilities are based principally on historic volatility of the Company’s common stock. The Company uses historical data to estimate forfeiture rate. The expected term of options represents the period of time that options granted are expected to be outstanding. The Company has made a determination of expected term by analyzing employees’ historical exercise experience and has made estimates of future exercises of unexercised options. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant corresponding with the expected life of the option. Recent Accounting Pronouncements In July 2013, the FASB issued Accounting Standards Update "Income Taxes (Topic 740): 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 requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss (NOL) carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) the entity intends to use the deferred tax asset for that purpose. ASU 2013-11 is effective prospectively for fiscal years and interim periods within those years, beginning after December 15, 2013 for public entities. The adoption of ASU 2013-11 did not have a significant impact on our consolidated financial statements. In May 2014, the FASB issued a comprehensive new revenue recognition Accounting Standards Update "Revenue from Contracts with Customers (Topic 606)" (ASU 2014-09). ASU 2014-09 provides guidance to clarify the principles for recognizing revenue. This guidance includes the required steps to achieve the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for fiscal years and interim periods beginning after December 15, 2016. Early adoption is not permitted. The Company expects to adopt this guidance when effective and is currently evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures.
