Some of these contracts are subject to milestone-based invoicing and services are completed over an extended period of time. The Company records liabilities under these contractual commitments when it determines an obligation has been incurred, regardless of the timing of the invoice. This process involves reviewing open contracts and purchase orders, communicating with applicable Company personnel to identify services that have been performed on its behalf and estimating the level of service performed and the associated cost incurred for the service when the Company has not yet been invoiced or otherwise notified of actual cost. The majority of service providers invoice the Company monthly in arrears for services performed. The Company makes estimates of accrued expenses as of each balance sheet date in its financial statements based on the facts and circumstances. The Company periodically confirms the accuracy of its estimates with the service providers and makes adjustments if necessary. Examples of estimated accrued expenses include:&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;table cellspacing="0" cellpadding="0" style="; border-collapse: collapse; font-size: 10pt; width: 700px;"&gt; &lt;tr&gt; &lt;td style="width: 5%"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="vertical-align: top; width: 2%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;&amp;#x2022;&lt;/div&gt;&lt;/td&gt; &lt;td style="vertical-align: top; width: 1%"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="vertical-align: top; width: 92%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;fees paid to Clinical Research Organizations (&amp;#x201c;CROs&amp;#x201d;) in connection with preclinical and toxicology studies and clinical trials;&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;&lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;table cellspacing="0" cellpadding="0" style="; border-collapse: collapse; font-size: 10pt; width: 700px;"&gt; &lt;tr&gt; &lt;td style="width: 5%"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="vertical-align: top; width: 2%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;&amp;#x2022;&lt;/div&gt;&lt;/td&gt; &lt;td style="vertical-align: top; width: 1%"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="vertical-align: top; width: 92%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;fees paid to investigative sites in connection with clinical trials;&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;&lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;table cellspacing="0" cellpadding="0" style="; border-collapse: collapse; font-size: 10pt; width: 700px;"&gt; &lt;tr&gt; &lt;td style="width: 5%"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="vertical-align: top; width: 2%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;&amp;#x2022;&lt;/div&gt;&lt;/td&gt; &lt;td style="vertical-align: top; width: 1%"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="vertical-align: top; width: 92%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;fees paid to contract manufacturers in connection with the production of our raw materials, drug substance and drug products;&amp;nbsp;and&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;&lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;table cellspacing="0" cellpadding="0" style="; border-collapse: collapse; font-size: 10pt; width: 700px;"&gt; &lt;tr&gt; &lt;td style="width: 5%"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="vertical-align: top; width: 2%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;&amp;#x2022;&lt;/div&gt;&lt;/td&gt; &lt;td style="vertical-align: top; width: 1%"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="vertical-align: top; width: 92%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;professional fees.&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Company bases its expenses related to clinical trials on its estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and CROs that conduct and manage clinical trials on the Company&amp;#x2019;s behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, the Company estimates the time period over which services will be performed and the level of effort expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company will adjust the accrual accordingly. As of June 30, 2015 and December 31, 2014, the carrying value of accrued expenses approximates their fair value due to their short-term settlement.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</bcrx:AccruedExpensesPolicyTextBlock>

These three pharmaceutical specialty distributors accounted for greater than 90% of all RAPIVAB product sales to date and accounted for predominantly all of the Company&amp;#x2019;s outstanding receivables from product sales. The loss of one or more of these specialty distributors as a customer could negatively impact the commercialization of RAPIVAB. However, the Company will utilize these specialty distributors on a limited basis subsequent to the CSL transaction as CSL will be responsible for commercial sales on a worldwide basis with the exception of Israel, Japan, Korea and Taiwan.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;The Company&amp;#x2019;s primary source of revenue that has an underlying cash flow stream is the reimbursement of RAPIVAB (i.e., peramivir) and BCX4430 development expenses, which was earned under cost-plus-fixed-fee contracts with BARDA/HHS and NIAID/HHS, respectively. The Company relies on BARDA/HHS and NIAID/HHS to reimburse predominantly all of the development costs for its RAPIVAB and BCX4430 programs. Accordingly, reimbursement of these expenses represents a significant portion of the Company&amp;#x2019;s collaborative and other research and development revenues. The completion, as with the June 30, 2014 BARDA/HHS peramivir development contract, or termination of the NIAID/HHS and BARDA/HHS BCX4430 programs/collaboration could negatively impact the Company&amp;#x2019;s future Consolidated Statements of Comprehensive Income (Loss) and Cash Flows. In addition, the Company also recognizes royalty revenue from the net sales of RAPIACTA; however, the underlying cash flow from these royalty payments goes directly to pay the interest, and then the principal, on the Company&amp;#x2019;s non-recourse notes payable. Payment of the interest and the ultimate repayment of principal of these notes will be entirely funded by future royalty payments derived from net sales of RAPIACTA. The Company&amp;#x2019;s drug development activities are performed by a limited group of third party vendors. If any of these vendors were unable to perform their services, this could significantly impact the Company&amp;#x2019;s ability to complete its drug development activities.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 27pt"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Risks from Third Party Manufacturing and Distribution Concentration&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 27pt; margin: 0pt 0"&gt;The Company relies on single source manufacturers for active pharmaceutical ingredient and finished product manufacturing of RAPIVAB. Additionally, the Company relies upon a single third party to provide warehousing and distribution services for RAPIVAB. Delays in the manufacture or distribution of any product could adversely impact the commercial revenue and future procurement stockpiling of RAPIVAB.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</bcrx:ConcentrationOfMarketRiskPolicyTextBlock>

The Currency Hedge Agreement does not qualify for hedge accounting treatment; therefore, mark-to-market adjustments are recognized in the Company&amp;#x2019;s Consolidated Statements of Comprehensive Income (Loss). Cumulative mark-to-market adjustments for the six months ended June 30, 2015 and 2014 resulted in losses of $332 and $3,350, respectively. Mark-to-market adjustments are determined by a third party pricing model that uses quoted prices in markets that are not actively traded and for which significant inputs are observable directly or indirectly, representing Level 2 in the fair value hierarchy as defined by U.S. GAAP. In addition, the Company realized a currency exchange gain of $1,545 during the first six months of 2015 associated with the exercise of a U.S. Dollar/Japanese yen currency option.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;The Company is also required to post collateral in connection with the mark-to-market adjustments based on thresholds defined in the Currency Hedge Agreement. As of June 30, 2015 and December 31, 2014, no hedge collateral was posted under the agreement.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</bcrx:CurrencyHedgeAgreementPolicyTextBlock>

(the &amp;#x201c;Company&amp;#x201d;) is a biotechnology company that designs, optimizes and develops novel small molecule drugs that block key enzymes involved in the pathogenesis of diseases. The Company focuses on the treatment of rare diseases in which significant unmet medical needs exist and align with its capabilities and expertise. The Company was incorporated in Delaware in 1986 and its headquarters is located in Durham, North Carolina. The Company integrates the disciplines of biology, crystallography, medicinal chemistry and computer modeling to discover and develop small molecule pharmaceuticals through the process known as structure-guided drug design. BioCryst has incurred losses and negative cash flows from operations since inception.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Based on its current operating plans, the Company expects it has sufficient liquidity, with its existing cash and investments of $131,993, to continue its planned operations into 2017. The Company&amp;#x2019;s liquidity needs, and ability to address those needs, will largely be determined by the success of its product candidates and key development and regulatory events in the future. In order to continue its operations substantially beyond 2017 it will need to: (1)&amp;nbsp;successfully secure or increase U.S. Government funding of its programs, including procurement contracts; (2)&amp;nbsp;out-license rights to certain of its products or product candidates, pursuant to which the Company would receive cash milestones; (3)&amp;nbsp;raise additional capital through equity or debt financings or from other sources; (4)&amp;nbsp;obtain additional product candidate regulatory approvals, which would generate revenue and cash flow; (5)&amp;nbsp;reduce spending on one or more research and development programs; and/or (6)&amp;nbsp;restructure operations. The Company retains the ability to offer for sale approximately $150,000 of securities, including common stock, preferred stock, depositary shares, stock purchase contracts, warrants, and units from its effective shelf S-3 registration statement, which it filed with the Securities and Exchange Commission on March 3, 2015.&amp;nbsp;&amp;nbsp;Additionally, the Company retains the ability to offer for sale approximately $10,000 of securities, including common stock, preferred stock, depositary shares, stock purchase contracts, warrants and units from its effective shelf S-3 registration statement, which it filed with the Securities and Exchange Commission on November&amp;nbsp;6, 2013. The Company will continue to incur operating losses and negative cash flows until revenues reach a level sufficient to support ongoing operations.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</bcrx:DescriptionOfCompanyPolicyTextBlock>

The Company received net proceeds of $22,691&amp;nbsp;from the transaction after transaction costs of $4,309&amp;nbsp;and the establishment of a $3,000&amp;nbsp;interest reserve account by Royalty Sub, available to help cover interest shortfalls in the future. All of the interest reserve account has been fully utilized with the September 2012 interest payment.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;As part of the transaction, the Company entered into a purchase and sale agreement dated as of March&amp;nbsp;9, 2011 with Royalty Sub, whereby the Company transferred to Royalty Sub, among other things, (i)&amp;nbsp;its rights to receive certain royalty and milestone payments from Shionogi arising under the Shionogi Agreement, and (ii)&amp;nbsp;the right to receive payments under a Japanese yen/US dollar foreign currency hedge arrangement (as further described below, the &amp;#x201c;Currency Hedge Agreement&amp;#x201d;) put into place by the Company in connection with the transaction. Royalty payments will be paid by Shionogi in Japanese yen and milestone payments will paid in U.S. dollars. The Company&amp;#x2019;s collaboration with Shionogi was not impacted as a result of this transaction.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Non-Recourse Notes Payable&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;On March&amp;nbsp;9, 2011, Royalty Sub completed a private placement to institutional investors of $30,000 in aggregate principal amount of its PhaRMA Senior Secured 14.0% Notes due 2020 (the &amp;#x201c;PhaRMA Notes&amp;#x201d;). The PhaRMA Notes were issued by Royalty Sub under an Indenture, dated as of March&amp;nbsp;9, 2011 (the &amp;#x201c;Indenture&amp;#x201d;), by and between Royalty Sub and U.S. Bank National Association, as Trustee. Principal and interest on the PhaRMA Notes issued are payable from, and are secured by, the rights to royalty and milestone payments under the Shionogi Agreement transferred by the Company to Royalty Sub and payments, if any, made to Royalty Sub under the Currency Hedge Agreement. The PhaRMA Notes bear interest at 14%&amp;nbsp;per annum, payable annually in arrears on September&amp;nbsp;1st of each year (the &amp;#x201c;Payment Date&amp;#x201d;). The Company remains entitled to receive any royalties and milestone payments related to sales of peramivir by Shionogi following repayment of the PhaRMA Notes. &amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Royalty Sub&amp;#x2019;s obligations to pay principal and interest on the PhaRMA Notes are obligations solely of Royalty Sub and are without recourse to any other person, including the Company, except to the extent of the Company&amp;#x2019;s pledge of its equity interests in Royalty Sub in support of the PhaRMA Notes. The Company may, but is not obligated to, make capital contributions to a capital account that may be used to redeem, or on up to one occasion pay any interest shortfall on, the PhaRMA Notes.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&lt;/div&gt;  &lt;!-- Field: Page; Sequence: 18; Value: 3 --&gt;      &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;On September&amp;nbsp;1, 2014, Royalty Sub was unable to pay the full amount of interest payable to avoid an event of default. Accordingly, the PhaRMA Notes and related accrued interest have been classified as current liabilities on the Consolidated Balance Sheet. As a result of the event of default under the PhaRMA Notes, the holders of the PhaRMA Notes may pursue acceleration of the PhaRMA Notes, may foreclose on the collateral securing the PhaRMA Notes and the equity interest in Royalty Sub and exercise other remedies available to them under the Indenture in respect of the PhaRMA Notes. In such event, the Company may not realize the benefit of future royalty payments that might otherwise accrue to it following repayment of the PhaRMA Notes and it might otherwise be adversely affected. Due to the non-recourse nature of the PhaRMA Notes, in the event of any potential acceleration or foreclosure, the primary impact to the Company would be the loss of future royalty payments from Shionogi and legal costs associated with retiring the PhaRMA Notes. In addition, the Company may incur costs associated with liquidating the related Currency Hedge Agreement, which would no longer be required in the event of foreclosure, or if the PhaRMA Notes cease to be outstanding. As the PhaRMA Notes are the obligation of Royalty Sub and non-recourse to the Company, the event of default of the PhaRMA Notes is not expected to have a significant impact on the Company&amp;#x2019;s future results of operations or cash flows.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Indenture does not contain any financial covenants. The Indenture includes customary representations and warranties of Royalty Sub, affirmative and negative covenants of Royalty Sub, Events of Default and related remedies, and provisions regarding the duties of the Trustee, indemnification of the Trustee, and other matters typical for indentures used in structured financings of this type.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;As of June 30, 2015, the aggregate fair value of the PhaRMA Notes was estimated to be approximately 50% of its carrying value of $30,000. The estimated fair value of the PhaRMA Notes is classified as Level 2 in the fair value hierarchy as defined in U.S. GAAP.&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The PhaRMA Notes are redeemable at the option of Royalty Sub at any time at a redemption price equal to the outstanding principal balance of the PhaRMA Notes being redeemed plus accrued and unpaid interest through the redemption date on the PhaRMA Notes being redeemed.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Foreign Currency Hedge&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;In connection with the issuance by Royalty Sub of the PhaRMA Notes, the Company entered into a Currency Hedge Agreement to hedge certain risks associated with changes in the value of the Japanese yen relative to the U.S. dollar. Under the Currency Hedge Agreement, the Company has the right to purchase dollars and sell yen at a rate of 100 yen per dollar for which the Company may be required to pay a premium in each year from 2015 through 2020, provided the Currency Hedge Agreement remains in effect. A payment of $1,950&amp;nbsp;will be required if, on May&amp;nbsp;18 of the relevant year, the U.S. dollar is worth 100 yen or less as determined in accordance with the Currency Hedge Agreement.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;The Currency Hedge Agreement does not qualify for hedge accounting treatment; therefore, mark-to-market adjustments are recognized in the Company&amp;#x2019;s Consolidated Statement of Comprehensive Income (Loss). Cumulative mark-to-market adjustments resulted in losses of $796 and $1,824 for the three months ended June&amp;nbsp;30, 2015 and 2014, respectively and losses of $332 and $3,350 for the six months ended June&amp;nbsp;30, 2015 and 2014, respectively. During the second quarter of 2015, the Company realized a currency exchange gain of $1,545 associated with the exercise of a U.S. Dollar/Japanese yen currency option. The Company is also required to post collateral in connection with the mark-to-market adjustments based on defined thresholds. As of June 30, 2015 and December&amp;nbsp;31, 2014, no collateral was posted under the Currency Hedge Agreement. The Company will not be required at any time to post collateral exceeding the maximum premium payments remaining payable under the Currency Hedge Agreement. As of June 30, 2015, the maximum amount of hedge collateral the Company may be required to post is $9,750.&lt;/div&gt;&lt;/div&gt;</bcrx:RoyaltyMonetizationTextBlock>

During 2009, peramivir clinical development shifted to focus on intravenous delivery and the treatment of hospitalized patients. To support this focus, a September 2009 contract modification was awarded to extend the i.v. peramivir program and to increase funding by $77,191. On February&amp;nbsp;24, 2011, the Company announced that BARDA/HHS had awarded it a $55,000 contract modification, intended to fund completion of the Phase 3 development of i.v. peramivir for the treatment of patients hospitalized with influenza. That contract modification brought the total contract award from BARDA/HHS to $234,852 and provided funding to support the filing of a NDA to seek regulatory approval for i.v. peramivir in the U.S. In December 2013, BioCryst submitted an NDA filing for i.v. peramivir to the FDA and the NDA was approved in December 2014. The BARDA/HHS contract expired on June 30, 2014 according to its terms.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&lt;/div&gt;  &lt;!-- Field: Page; Sequence: 15; Value: 3 --&gt;      &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;On March 31, 2015, the Company announced that the Biomedical Research and Development Authority within the U.S. Department of Health and Human Services&amp;#x2019; Office of the Assistant Secretary for Preparedness and Response (&amp;#x201c;ASPR&amp;#x201d;) awarded BioCryst a contract for the continued development of BCX4430 as a potential treatment for diseases caused by RNA pathogens, including filoviruses.&amp;nbsp;This BARDA/HHS contract includes a base contract of $12,134 to support BCX4430 drug manufacturing, as well as $22,855 in additional development options that can be exercised by the government, bringing the potential value of the contract to $34,989. As of June 30, 2015, a total of $11,157 has been awarded under exercised options within this contract.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;National Institute of Allergy and Infectious Diseases (&amp;#x201c;NIAID/HHS&amp;#x201d;).&lt;/div&gt; In September 2013, NIAID/HHS contracted with the Company for the development of BCX4430 as a treatment for Marburg virus disease. NIAID/HHS, part of the National Institutes of Health, made an initial award of $5,000 to the Company. The total funding under this contract as of June 30, 2015 could be up to $30,472, if all contract options are exercised by NIAID/HHS, over a five year period. The goals of this contract, including amendments, are to file IND applications for intravenous and intramuscular BCX4430 for the treatment of Marburg virus disease, to study BCX4430 as a treatment for Ebola virus disease and to conduct an initial Phase 1 human clinical trial. As of June 30, 2015, a total of $26,346 has been awarded under exercised options within this contract. BCX4430 is the lead compound in the Company&amp;#x2019;s BSAV research program.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The contracts with BARDA/HHS and NIAID/HHS are cost-plus-fixed-fee contracts. That is, the Company is entitled to receive reimbursement for all costs incurred in accordance with the contracts provisions that are related to the development of peramivir and BCX4430 plus a fixed fee, or profit. BARDA/HHS and NIAID/HHS will make periodic assessments of progress and the continuation of the contract is based on the Company&amp;#x2019;s performance, the timeliness and quality of deliverables, and other factors. The government has rights under certain contract clauses to terminate these contracts. These contracts are terminable by the government at any time for breach or without cause.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0; text-indent: 0.5in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;CSL Limited (&amp;#x201c;CSL&amp;#x201d;). &lt;/div&gt;On June 16, 2015, the Company and Seqirus UK Limited (&amp;quot;SUL&amp;quot;), a limited company organized under the laws of the United Kingdom and a subsidiary of CSL, a company organized under the laws of Australia, entered into a License Agreement (the &amp;quot;Agreement&amp;quot;) granting SUL and its affiliates worldwide rights to develop, manufacture and commercialize RAPIVAB (peramivir injection) for the treatment of influenza except for the rights to conduct such activities in Israel, Japan, Korea and Taiwan (the permitted geographies together constituting the &amp;quot;Territory&amp;quot;). RAPIVAB is an intravenous treatment for acute uncomplicated influenza and is currently licensed for use in the United States, Japan and Korea. RAPIVAB is the first and only intravenous influenza treatment in the world and was approved by the U.S. Food and Drug Administration in December 2014 for the treatment of acute uncomplicated influenza in patients 18 years and older who have been symptomatic for no more than two days. The Company retains all rights and associated economics to procure pandemic stockpiling orders for RAPIVAB from the U.S. Government, while SUL has the right to pursue government stockpiling outside the U.S.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;Pursuant to the Agreement, RAPIVAB will be commercialized by CSL's subsidiary, bioCSL, which specializes in influenza prevention through the supply of seasonal and pandemic vaccine to global markets. bioCSL will manufacture, commercialize and exercise decision-making authority with respect to the development and commercialization of RAPIVAB within the Territory and be responsible for all related costs, including sales and promotion. The Company will exercise sole decision-making authority with regard to the development and commercialization of RAPIVAB outside of the Territory and is responsible for all associated costs.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;In December 2013, the Company submitted a New Drug Application (&amp;quot;NDA&amp;quot;) to the FDA. Under the terms of the Agreement, the Company is responsible for fulfilling all post-marketing approval commitments in connection with the FDA's approval of the NDA, and upon fulfillment will transfer ownership of and financial responsibility for the NDA to SUL. Pursuant to potential rights to sell RAPIVAB in Canada and the European Union, the Company is also responsible for regulatory filings and interactions with the Health Products and Food Branch of Health Canada (&amp;quot;Health Canada&amp;quot;) and the European Medicines Agency (&amp;quot;EMA&amp;quot;) until marketing approval for RAPIVAB is obtained and assigned to SUL. In accordance with the Agreement, the Company and SUL will also form a joint steering committee, composed of an equal number of representatives from each party, to oversee, review and coordinate the conduct and progress of the commercialization of RAPIVAB in the Territory and any additional development.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 11.25pt 0 0"&gt;Under the terms of the Agreement, the Company received an upfront payment of $33,740, and may receive up to $12,000 in additional milestone payments related to the successful achievement of regulatory milestones, including marketing approval (i) by the FDA for a pediatric indication, (ii) by the EMA for an adult indication in the European Union and (iii) by Health Canada for an adult indication in Canada. The Company is also entitled under the Agreement to receive tiered royalties at a percentage rate beginning in the mid-teens contingent upon meeting minimum thresholds of net sales, as well as a low-thirties percentage of the gross profit from government stockpiling purchases made outside the U.S. Specifically, the Company receives tiered royalties at a percentage rate in the mid-teens to low-forties on net sales in the U.S. during a Contract Year (defined as July 1- June 30) and tiered royalties at a percentage rate in the mid-teens to mid-twenties on net sales in the Territory, other than in the U.S., during a Calendar Year, each subject to certain downward adjustments for circumstance or events impacting the overall market opportunity. SUL's royalty payment obligations commence on the date of the Agreement and expire, on a country-by-country basis, upon the later of (i) the expiration of legal exclusivity in such country and (ii) ten years from the date of the Agreement (the &amp;quot;Royalty Term&amp;quot;). The Company developed RAPIVAB under a license from UAB and will owe sublicense payments to them on any future milestone payments and/or royalties received by the Company from SUL.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&lt;/div&gt;  &lt;!-- Field: Page; Sequence: 16; Value: 3 --&gt;      &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 11.25pt 0 0"&gt;The term of the Agreement shall continue on a country-by-country basis until the expiration of the last-to-expire Royalty Term in any such country in the Territory. Either party may terminate the Agreement in its entirety if the other party breaches a payment obligation, otherwise materially breaches the Agreement, subject to applicable cure periods, or if the other party suffers an insolvency event. The Company may also terminate the Agreement if SUL or any of its affiliates seek to challenge the validity of the Company's patents. Termination does not affect a party's rights which have accrued prior thereto, but there are no stated payments in connection with termination other than payments of obligations previously accrued. For all terminations exercised by the Company, the Agreement provides for the termination of any sublicenses granted by SUL to third parties, and in the case of termination by the Company for cause, the ceasing of SUL's activities with respect to RAPIVAB, the discontinued use of all Company intellectual property and the termination of licenses and rights previously granted to SUL. If requested by the Company, SUL shall also promptly sell to the Company all licensed product it then holds in stock, otherwise, SUL may continue to sell such licensed product for designated periods.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Shionogi&amp;nbsp;&amp;amp; Co., Ltd. (&amp;#x201c;Shionogi&amp;#x201d;).&lt;/div&gt; In February 2007, the Company entered into an exclusive license agreement with Shionogi to develop and commercialize peramivir in Japan for the treatment of seasonal and potentially life-threatening human influenza. Under the terms of the agreement, Shionogi obtained rights to injectable formulations of peramivir in Japan. The Company developed peramivir under a license from UAB and will owe sublicense payments to them on any future milestone payments and/or royalties received by the Company from Shionogi. In October 2008, the Company and Shionogi amended the license agreement to expand the territory covered by the agreement to include Taiwan and to provide rights for Shionogi to perform a Phase&amp;nbsp;3 clinical trial in Hong Kong. Shionogi has commercially launched peramivir under the commercial name RAPIACTA in Japan. Shionogi submitted an NDA to the Taiwan FDA in late 2013.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Green Cross Corporation (&amp;#x201c;Green Cross&amp;#x201d;).&lt;/div&gt; In June 2006, the Company entered into an agreement with Green Cross to develop and commercialize peramivir in Korea. Under the terms of the agreement, Green Cross will be responsible for all development, regulatory, and commercialization costs in Korea. The Company received a one-time license fee of $250. The license also provides that the Company will share in profits resulting from the sale of peramivir in Korea, including the sale of peramivir to the Korean government for stockpiling purposes. Furthermore, Green Cross will pay the Company a premium over its cost to supply peramivir for development and any future marketing of peramivir products in Korea.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Mundipharma International Holdings Limited (&amp;#x201c;Mundipharma&amp;#x201d;).&lt;/div&gt; In February 2006, the Company entered into an exclusive, royalty bearing right and license agreement with Mundipharma for the development and commercialization of forodesine, a Purine Nucleoside Phosphorylase (&amp;#x201c;PNP&amp;#x201d;) inhibitor, for use in oncology (the &amp;#x201c;Original Agreement&amp;#x201d;). Under the terms of the license agreement, as amended, Mundipharma obtained worldwide rights to forodesine. &amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Albert Einstein College of Medicine of Yeshiva University and Industrial Research, Ltd. (&amp;#x201c;AECOM&amp;#x201d; and &amp;#x201c;IRL&amp;#x201d; respectively).&lt;/div&gt; In June 2000, the Company licensed a series of potent inhibitors of PNP from AECOM and IRL, (collectively, the &amp;#x201c;Licensors&amp;#x201d;). The lead product candidates from this collaboration are forodesine and ulodesine. The Company has obtained worldwide exclusive rights to develop and ultimately distribute these, or any other, product candidates that might arise from research on these inhibitors. The Company has the option to expand the Agreement to include other inventions in the field made by the investigators or employees of the Licensors. The Company agreed to use commercially reasonable efforts to develop these drugs. In addition, the Company has agreed to pay certain milestone payments for each licensed product (which range in the aggregate from $1,400 to almost $4,000&amp;nbsp;per indication) for future development of these inhibitors, single digit royalties on net sales of any resulting product made by the Company, and to share approximately one quarter of future payments received from other third-party partners, if any. In addition, the Company has agreed to pay annual license fees, which can range from $150 to $500, that are creditable against actual royalties and other payments due to the Licensors. This agreement may be terminated by the Company at any time by giving 60&amp;nbsp;days advance notice or in the event of material uncured breach by the Licensors.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;In May 2010, the Company amended the licensee agreement through which the Company obtained worldwide exclusive rights to develop and ultimately distribute any product candidates that might arise from research on a series of PNP inhibitors, including forodesine and ulodesine. Under the terms of the amendment, the Licensors agreed to accept a reduction of one-half in the percentage of future payments received from third-party sub licensees of the licensed PNP inhibitors that must be paid to the Licensors. This reduction does not apply to (i)&amp;nbsp;any milestone payments the Company may receive in the future under its license agreement dated February&amp;nbsp;1, 2006 with Mundipharma and (ii)&amp;nbsp;royalties received from its sub licensees in connection with the sale of licensed products, for which the original payment rate will remain in effect. The rate of royalty payments to the Licensors based on net sales of any resulting product made by the Company remains unchanged.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;In consideration for these modifications in 2010, the Company issued to the Licensors shares of its common stock with an aggregate value of $5,911 and paid the Licensors $90 in cash. Additionally, at the Company&amp;#x2019;s sole option and subject to certain agreed upon conditions, any future non-royalty payments due to be paid by it to the Licensors under the license agreement may be made either in cash, in shares of its common stock, or in a combination of cash and shares.&lt;/div&gt;    &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&lt;/div&gt;  &lt;!-- Field: Page; Sequence: 17; Value: 3 --&gt;      &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;On November&amp;nbsp;17, 2011, the Company further amended its agreements with the Licensors whereby the Licensors agreed to accept a reduction of one-half in the percentage of Net Proceeds (as defined) received by the Company under its Amended and Restated Agreement with Mundipharma that will be paid to AECOM/IRL.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;On June&amp;nbsp;19, 2012, the Company further amended its agreements with AECOM/IRL whereby the parties clarified the definition of the field with respect to PNP inhibition and AECOM/IRL agreed to exclusive worldwide license of BCX4430 to BioCryst for any antiviral use.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;At its sole option and subject to certain agreed upon conditions, any future non-royalty payments due to be paid by the Company to AECOM/IRL under the license agreement may be made either in cash, in shares of the Company&amp;#x2019;s common stock, or in a combination of cash and shares.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;On January 6, 2014, the Carbohydrate Chemistry Research Team from Callaghan Innovation Research Limited (&amp;#x201c;CIRL&amp;#x201d;), formerly Industrial Research Limited, transferred to Victoria University of Wellington (&amp;#x201c;VUW&amp;#x201d;) to establish the Ferrier Research Institute. The intellectual property rights relating to this research team, and the contracts relating to that intellectual property were transferred to a wholly owned subsidiary of VUW, including the contracts to which BioCryst is a party. The parties executed novation agreements in order to effectuate the transfer. Except for a substitution of parties, the terms and conditions of the contracts are substantially the same.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;The University of Alabama at Birmingham (&amp;#x201c;UAB&amp;#x201d;).&lt;/div&gt; The Company currently has agreements with UAB for influenza neuraminidase and complement inhibitors. Under the terms of these agreements, UAB performed specific research for the Company in return for research payments and license fees. UAB has granted the Company certain rights to any discoveries in these areas resulting from research developed by UAB or jointly developed with the Company. The Company has agreed to pay single digit royalties on sales of any resulting product and to share in future payments received from other third-party partners. The Company has completed the research under the UAB agreements. These two agreements have initial 25-year terms, are automatically renewable for five-year terms throughout the life of the last patent and are terminable by the Company upon three months&amp;#x2019; notice and by UAB under certain circumstances. Upon termination both parties shall cease using the other parties&amp;#x2019; proprietary and confidential information and materials, the parties shall jointly own joint inventions and UAB shall resume full ownership of all UAB licensed products. There is currently no activity between the Company and UAB on these agreements, but when the Company licenses this technology, such as in the case of the Shionogi, Green Cross and CSL agreements, or commercializes products related to these programs, the Company will owe sublicense fees or royalties on amounts it receives.&lt;/div&gt;&lt;/div&gt;</us-gaap:CollaborativeArrangementDisclosureTextBlock>

Stock-based compensation expense of $5,934 ($5,840 of expense related to the Incentive Plan and $94 of expense related to the ESPP) was recognized during the first six months of 2015, while $5,129 ($5,020 of expense related to the Incentive Plan and $109 of expense related to the ESPP) was recognized during the first six months of 2014.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;There was approximately $15,169 of total unrecognized compensation cost related to non-vested stock option awards and restricted stock unit awards granted by the Company as of June 30, 2015. That cost is expected to be recognized as follows: $3,164 during the remainder of 2015, $5,192 in 2016, $4,396 in 2017, $2,277 in 2018 and $140 in 2019. In addition, the Company has approximately $11,982 of unrecognized compensation cost related to outstanding performance-based stock options for which no compensation expense is recognized until &amp;#x201c;performance&amp;#x201d; has occurred and the award vests. At the time of vesting, compensation expense will be recognized.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Stock Incentive Plan&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: left; margin-top: 0pt; margin-right: 0; margin-bottom: 0pt"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: left; margin-top: 0pt; margin-right: 0; margin-bottom: 0pt; text-indent: 27pt"&gt;The Company grants stock option awards and restricted stock unit awards to its employees, directors, and consultants under the Incentive Plan. Under the Incentive Plan, stock option awards are granted with an exercise price equal to the market price of the Company&amp;#x2019;s stock at the date of grant. Commencing March&amp;nbsp;1, 2011, stock option awards granted to employees generally vest 25% each year until fully vested after four years. In January 2013, the Company made retention grants of stock option awards and restricted stock units. These awards vest 50% each year until fully vested after two years. In August 2013 and December 2014, the Company issued 1,032 and 1,250 performance-based stock options, respectively. These awards vest upon successful completion of specific development milestones. As of June 30, 2015, 75% of the August 2013 grants have vested based upon achievement of three milestones: (1) successful completion of the OPuS-1 clinical trial for which vesting occurred in the second quarter of 2014, (2) FDA approval of RAPIVAB for which vesting occurred in the fourth quarter of 2014, and (3) initiation of a Phase 1 clinical trial to evaluate the safety, pharmacokinetics and pharmacodynamics of orally-administered BCX-7353 in healthy volunteers for which vesting occurred in the second quarter of 2015. Thus, as of June 30, 2015, 25% of the August 2013 performance-based grants and 100% of the December 2014 performance-based grants remain unvested and no compensation expense has been recognized for these portions of the previously issued performance-based grants. Stock option awards granted to non-employee directors of the Company generally vest monthly over one year. All stock option awards have contractual terms of 5 to 10&amp;nbsp;years. The vesting exercise provisions of all awards granted under the Incentive Plan are subject to acceleration in the event of certain stockholder-approved transactions, or upon the occurrence of a change in control as defined in the Incentive Plan.&lt;/div&gt;

The weighted average grant date fair value per share of the awards granted during the first six months of 2015 and 2014 was $8.21 and $8.11, respectively. The fair value of the stock option awards is amortized to expense over the vesting periods using a straight-line expense attribution method. The following table summarizes the key assumptions used by the Company to value the stock option awards granted during the first six months of 2015 and 2014. The expected life is based on the average of the assumption that all outstanding stock option awards will be exercised at full vesting and the assumption that all outstanding stock option awards will be exercised at the midpoint of the current date (if already vested) or at full vesting (if not yet vested) and the full contractual term. The expected volatility represents the historical volatility on the Company&amp;#x2019;s publicly traded common stock. The Company has assumed no expected dividend yield, as dividends have never been paid to stock or option holders and will not be paid for the foreseeable future. The weighted average risk-free interest rate is the implied yield currently available on zero-coupon government issues with a remaining term equal to the expected term.&lt;/div&gt;  &lt;div style=" font-size: 10pt;

The objective of the Company&amp;#x2019;s investment policy is to ensure the safety and preservation of invested funds, as well as maintaining liquidity sufficient to meet cash flow requirements. The Company places its excess cash with high credit quality financial institutions, commercial companies, and government agencies in order to limit the amount of its credit exposure. In accordance with its policy, the Company is able to invest in marketable debt securities that may consist of U.S. Government and government agency securities, money market and mutual fund investments, municipal and corporate notes and bonds, commercial paper and asset or mortgage-backed securities, among others. The Company&amp;#x2019;s investment policy requires it to purchase high-quality marketable securities with a maximum individual maturity of three years and requires an average portfolio maturity of no more than 18 months. Some of the securities the Company invests in may have market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, the Company schedules its investments with maturities that coincide with expected cash flow needs, thus avoiding the need to redeem an investment prior to its maturity date. Accordingly, the Company does not believe it has a material exposure to interest rate risk arising from its investments. Generally, the Company&amp;#x2019;s investments are not collateralized. The Company has not realized any significant losses from its investments.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Company classifies all of its investments as available-for-sale. Unrealized gains and losses on investments are recognized in comprehensive loss, unless an unrealized loss is considered to be other than temporary, in which case the unrealized loss is charged to operations. The Company periodically reviews its investments for other than temporary declines in fair value below cost basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company believes the individual unrealized losses represent temporary declines primarily resulting from interest rate changes. Realized gains and losses are reflected in interest and other income in the Consolidated Statements of Comprehensive Income (Loss) and are determined using the specific identification method with transactions recorded on a settlement date basis. Investments with original maturities at date of purchase beyond three months and which mature at or less than 12 months from the balance sheet date are classified as current. Investments with a maturity beyond 12 months from the balance sheet date are classified as long-term. At June 30, 2015, the Company believes that the costs of its investments are recoverable in all material respects.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The following tables summarize the fair value of the Company&amp;#x2019;s investments by type. The estimated fair value of the Company&amp;#x2019;s fixed income investments are classified as Level 2 in the fair value hierarchy as defined in U.S. GAAP. These valuations are based on observable direct and indirect inputs, primarily quoted prices of similar, but not identical, instruments in active markets or quoted prices for identical or similar instruments in markets that are not active. These fair values are obtained from independent pricing services which utilize Level 2 inputs.&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div&gt;

This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company does not expect this ASU will have a material impact on its consolidated financial statements.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;In May 2014, the FASB issued ASU 2014-09 &amp;#x2013; &lt;div style="display: inline; font-style: italic;"&gt;Revenue from Contracts with Customers&lt;/div&gt;, which provides a single, comprehensive revenue recognition model for all contracts with customers. The core principal of this ASU is that an entity should recognize revenue when it transfers 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 ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In July 2015, the FASB finalized a one year delay in the effective date of this standard, which will now be effective January 1, 2018, however early adoption is permitted any time after the original effective date, January 1, 2017. Companies can transition to the new standard under the full retrospective method or the modified retrospective method. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

Research and development expenses include all direct and indirect development costs related to the development of the Company&amp;#x2019;s portfolio of product candidates. Advance payments for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts are recognized as expense when the related goods are delivered or the related services are performed. Research and development expenses include, among other items, personnel costs, including salaries and benefits, manufacturing costs, clinical, regulatory, and toxicology services performed by CROs, materials and supplies, and overhead allocations consisting of various administrative and facilities related costs. Most of the Company&amp;#x2019;s manufacturing and clinical and preclinical studies are performed by third-party CROs. Costs for studies performed by CROs are accrued by the Company over the service periods specified in the contracts and estimates are adjusted, if required, based upon the Company&amp;#x2019;s on-going review of the level of services actually performed.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Additionally, the Company has license agreements with third parties, such as Albert Einstein College of Medicine of Yeshiva University (&amp;#x201c;AECOM&amp;#x201d;), Industrial Research, Ltd.

Revenue is realized or realizable and earned when all of the following criteria are met: (i)&amp;nbsp;persuasive evidence of an arrangement exists; (ii)&amp;nbsp;delivery has occurred or services have been rendered; (iii)&amp;nbsp;the seller&amp;#x2019;s price to the buyer is fixed or determinable; and (iv)&amp;nbsp;collectability is reasonably assured.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Collaborative and Other Research and Development Arrangements and Royalties&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Revenue from license fees, royalty payments, event payments, and research and development fees are recognized as revenue when the earnings process is complete and the Company has no further continuing performance obligations or the Company has completed the performance obligations under the terms of the agreement. Fees received under licensing agreements that are related to future performance are deferred and recognized over an estimated period determined by management based on the terms of the agreement and the products licensed. Revisions to revenue or profit estimates as a result of changes in the estimated revenue period are recognized prospectively.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Under certain of the Company&amp;#x2019;s license agreements, the Company receives royalty payments based upon its licensees&amp;#x2019; net sales of covered products. The Company recognizes royalty revenues when it can reliably estimate such amounts and collectability is reasonably assured.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;For arrangements that involve the delivery of more than one element, each product, service and/or right to use assets is evaluated to determine whether it qualifies as a separate unit of accounting. This determination is based on whether the deliverable has &amp;#x201c;stand-alone value&amp;#x201d; to the customer. The consideration that is fixed or determinable is then allocated to each separate unit of accounting based on the relative selling price of each deliverable. The estimated selling price of each deliverable is determined using the following hierarchy of values: (i) vendor-specific objective evidence of fair value, (ii) third-party evidence of selling price (&amp;#x201c;TPE&amp;#x201d;) and (iii) best estimate of selling price (&amp;#x201c;BESP&amp;#x201d;). The BESP reflects our best estimate of what the selling price would be if the deliverable was regularly sold by the Company on a stand-alone basis. In most cases the Company expects to use TPE or BESP for allocating consideration to each deliverable. The consideration allocated to each unit of accounting is recognized as the related goods or services are delivered, limited to the consideration that is not contingent upon future deliverables. Analyzing the arrangement to identify deliverables requires the use of judgment, and each deliverable may be an obligation to deliver services, a right or license to use an asset, or another performance obligation.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;In June 2015, the Company entered into a License Agreement (the &amp;#x201c;Agreement&amp;#x201d;) granting CSL Limited (&amp;#x201c;CSL&amp;#x201d;) and its affiliates worldwide rights, excluding Israel, Japan, Korea and Taiwan, to develop, manufacture and commercialize RAPIVAB. The Agreement provides for various types of payments, including a non-refundable upfront fee, milestone payments, and future royalties. Analysis of the Agreement identified three deliverables: (i) license rights, (ii) inventory and (iii) regulatory support to obtain Canadian and European Union (&amp;#x201c;EU&amp;#x201d;) marketing approvals. The Company received an upfront payment of $33,740 from CSL of which $7,000 was determined to be contingent upon EU marketing approval and will be deferred until that time. Approximately $21,777 of the upfront payment was allocated to the license rights and recognized as revenue in the current quarter. Approximately $3,740 of the upfront payment was allocated to the pending sale of inventory and was deferred. This deferred revenue will be recognized when the inventory transfer is complete. Approximately $1,223 of this revenue will be recognized over the expected period of involvement in these regulatory support activities.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Milestone payments are recognized as licensing revenue upon the achievement of specified milestones if (i) the milestone is substantive in nature and the achievement of the milestone was not reasonably assured at the inception of the agreement; and (ii) the fees are non-refundable. Any milestone payments received prior to satisfying these revenue recognition criteria are recorded as deferred revenue.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Under the terms of the Agreement, the Company may receive up to $12,000 in additional payments related to the successful achievement of regulatory milestones, including marketing approval (i) by the FDA for a pediatric indication, (ii) by the EMA for an adult indication in the European Union and (iii) by Health Canada for an adult indication in Canada. The Company evaluated each event based payment under the provisions of ASU 2010-17, &lt;div style="display: inline; font-style: italic;"&gt;Milestone Method of Revenue Recognition&lt;/div&gt;, and determined that each event based payment met the criteria to be considered substantive and represents a milestone under the milestone method of accounting. No event based payments were achieved during the periods presented.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Reimbursements received for direct out-of-pocket expenses related to research and development costs are recorded as revenue in the Consolidated Statements of Comprehensive Income (Loss) rather than as a reduction in expenses. Under the Company&amp;#x2019;s contracts with the Biomedical Advanced Research and Development Authority within the United States Department of Health and Human Services (&amp;#x201d;BARDA/HHS&amp;#x201d;) and the National Institute of Allergy and Infectious Diseases (&amp;#x201c;NIAID/HHS&amp;#x201d;), revenue is recognized as reimbursable direct and indirect costs are incurred.&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 20pt; text-align: left"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Product Sales&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 20pt; text-align: left"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;The Company recognizes revenue for sales of RAPIVAB when title and substantially all the risks and rewards of ownership have transferred to the customer, which generally occurs on the date of shipment from our specialty distributors, utilizing the Sell-Through revenue recognition methodology. Product sales are recognized when there is persuasive evidence that an arrangement exists, title has passed, the price is fixed and determinable, and collectability is reasonably assured. Product sales are recognized net of estimated allowances, discounts, sales returns, chargebacks and rebates. In the United States, the Company sells RAPIVAB to specialty distributors, who in turn, sell to physician offices, hospitals and federal, state and commercial health care organizations.&amp;nbsp;With the completion of the CSL worldwide license of RAPIVAB, CSL will be primarily responsible for sales of RAPIVAB other than U.S. Government stockpiling sales and the Company&amp;#x2019;s commercial sales will be minimal.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Sales deductions consist of statutory rebates to state Medicaid, Medicare and other government agencies and sales discounts (including trade discounts and distribution service fees). These deductions are recorded as reductions from revenue from RAPIVAB in the same period as the related sales with estimates of future utilization derived from historical experience adjusted to reflect known changes in the factors that impact such reserves.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Company utilizes data from external sources to help it estimate gross-to-net sales adjustments as they relate to the recognition of revenue for RAPIVAB sold. Externally sourced data includes, but is not limited to, information obtained from specialty distributors with respect to their inventory levels and their sell-through to customers, as well as information from third-party suppliers of market research data to the pharmaceutical industry.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Company accounts for these sales deductions in accordance with authoritative guidance on revenue recognition when consideration is given by a vendor to a customer.&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Company has categorized and described more fully the following significant sales deductions, all of which involve estimates and judgments, which the Company considers to be critical accounting estimates, and require it to use information from external sources.&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Rebates and Chargebacks&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Statutory rebates to state Medicaid agencies and Medicare are based on statutory discounts to RAPIVAB&amp;#x2019;s selling price.&amp;nbsp;As it can take up to nine months or more for information to be received on actual usage of RAPIVAB in Medicaid and other governmental programs, the Company maintains reserves for amounts payable under these programs relating to RAPIVAB sales.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Chargebacks claimed by specialty distributors are based on the differentials between product acquisition prices paid by the specialty distributors and lower government contract pricing paid by eligible customers covered under federally qualified programs.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The amount of the reserve for rebates and chargebacks is based on multiple qualitative and quantitative factors, including the historical and projected utilization levels, historical payment experience, changes in statutory laws and interpretations as well as contractual terms, product pricing (both normal selling prices and statutory or negotiated prices), changes in prescription demand patterns and utilization of the Company&amp;#x2019;s product through public benefit plans, and the levels of RAPIVAB inventory in the distribution channel. The Company acquires prescription utilization data from third-party suppliers of market research data to the pharmaceutical industry. The Company updates its estimates and assumptions each period and records any necessary adjustments to its reserves. Settlements of rebates and chargebacks typically occur within nine months from point of sale. To the extent actual rebates and chargebacks differ from the Company&amp;#x2019;s estimates, additional reserves may be required or reserves may need to be reversed, either of which would impact current period product revenue.&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Discounts and Sales Incentives&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Discounts and other sales incentives primarily consist of Inventory Management Agreement (&amp;#x201c;IMA&amp;#x201d;) Fees. Per contractual agreements with the Company&amp;#x2019;s specialty distributors, the Company provides an IMA fee based on a percentage of their purchases of RAPIVAB. The IMA fee rates are set forth in individual contracts. The Company tracks sales to these distributors each period and accrues a liability relating to the unpaid portion of these fees by applying the contractual rates to such product sales.&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Product Returns&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt;

text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Advertising&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt;

(the &amp;#x201c;Company&amp;#x201d;) is a biotechnology company that designs, optimizes and develops novel small molecule drugs that block key enzymes involved in the pathogenesis of diseases. The Company focuses on the treatment of rare diseases in which significant unmet medical needs exist and align with its capabilities and expertise. The Company was incorporated in Delaware in 1986 and its headquarters is located in Durham, North Carolina. The Company integrates the disciplines of biology, crystallography, medicinal chemistry and computer modeling to discover and develop small molecule pharmaceuticals through the process known as structure-guided drug design. BioCryst has incurred losses and negative cash flows from operations since inception.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Based on its current operating plans, the Company expects it has sufficient liquidity, with its existing cash and investments of $131,993, to continue its planned operations into 2017. The Company&amp;#x2019;s liquidity needs, and ability to address those needs, will largely be determined by the success of its product candidates and key development and regulatory events in the future. In order to continue its operations substantially beyond 2017 it will need to: (1)&amp;nbsp;successfully secure or increase U.S. Government funding of its programs, including procurement contracts; (2)&amp;nbsp;out-license rights to certain of its products or product candidates, pursuant to which the Company would receive cash milestones; (3)&amp;nbsp;raise additional capital through equity or debt financings or from other sources; (4)&amp;nbsp;obtain additional product candidate regulatory approvals, which would generate revenue and cash flow; (5)&amp;nbsp;reduce spending on one or more research and development programs; and/or (6)&amp;nbsp;restructure operations. The Company retains the ability to offer for sale approximately $150,000 of securities, including common stock, preferred stock, depositary shares, stock purchase contracts, warrants, and units from its effective shelf S-3 registration statement, which it filed with the Securities and Exchange Commission on March 3, 2015.&amp;nbsp;&amp;nbsp;Additionally, the Company retains the ability to offer for sale approximately $10,000 of securities, including common stock, preferred stock, depositary shares, stock purchase contracts, warrants and units from its effective shelf S-3 registration statement, which it filed with the Securities and Exchange Commission on November&amp;nbsp;6, 2013. The Company will continue to incur operating losses and negative cash flows until revenues reach a level sufficient to support ongoing operations.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Basis of Presentation&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, JPR Royalty Sub LLC (&amp;#x201c;Royalty Sub&amp;#x201d;). Royalty Sub was formed in connection with a $30,000&amp;nbsp;financing transaction the Company completed on March&amp;nbsp;9, 2011.

Interim operating results are not necessarily indicative of operating results for the full year.

The carrying value of cash and cash equivalents approximates fair value due to the short-term nature of these items.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;/div&gt;  &lt;!-- Field: Page; Sequence: 6; Value: 3 --&gt;      &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Restricted Cash&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Restricted cash as of June 30, 2015 reflects $150 the Company is required to maintain in an interest bearing certificate of deposit to serve as collateral for a corporate credit card program, $18 in royalty revenue paid by Shionogi&amp;nbsp;&amp;amp; Co., Ltd.

The objective of the Company&amp;#x2019;s investment policy is to ensure the safety and preservation of invested funds, as well as maintaining liquidity sufficient to meet cash flow requirements. The Company places its excess cash with high credit quality financial institutions, commercial companies, and government agencies in order to limit the amount of its credit exposure. In accordance with its policy, the Company is able to invest in marketable debt securities that may consist of U.S. Government and government agency securities, money market and mutual fund investments, municipal and corporate notes and bonds, commercial paper and asset or mortgage-backed securities, among others. The Company&amp;#x2019;s investment policy requires it to purchase high-quality marketable securities with a maximum individual maturity of three years and requires an average portfolio maturity of no more than 18 months. Some of the securities the Company invests in may have market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, the Company schedules its investments with maturities that coincide with expected cash flow needs, thus avoiding the need to redeem an investment prior to its maturity date. Accordingly, the Company does not believe it has a material exposure to interest rate risk arising from its investments. Generally, the Company&amp;#x2019;s investments are not collateralized. The Company has not realized any significant losses from its investments.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Company classifies all of its investments as available-for-sale. Unrealized gains and losses on investments are recognized in comprehensive loss, unless an unrealized loss is considered to be other than temporary, in which case the unrealized loss is charged to operations. The Company periodically reviews its investments for other than temporary declines in fair value below cost basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company believes the individual unrealized losses represent temporary declines primarily resulting from interest rate changes. Realized gains and losses are reflected in interest and other income in the Consolidated Statements of Comprehensive Income (Loss) and are determined using the specific identification method with transactions recorded on a settlement date basis. Investments with original maturities at date of purchase beyond three months and which mature at or less than 12 months from the balance sheet date are classified as current. Investments with a maturity beyond 12 months from the balance sheet date are classified as long-term. At June 30, 2015, the Company believes that the costs of its investments are recoverable in all material respects.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The following tables summarize the fair value of the Company&amp;#x2019;s investments by type. The estimated fair value of the Company&amp;#x2019;s fixed income investments are classified as Level 2 in the fair value hierarchy as defined in U.S. GAAP. These valuations are based on observable direct and indirect inputs, primarily quoted prices of similar, but not identical, instruments in active markets or quoted prices for identical or similar instruments in markets that are not active. These fair values are obtained from independent pricing services which utilize Level 2 inputs.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;

text-indent: 27pt; margin: 0pt 0"&gt;The Company seeks patent protection on all internally developed processes and products. All patent related costs are expensed to general and administrative expenses when incurred as recoverability of such expenditures is uncertain.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Accrued Expenses&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Company generally enters into contractual agreements with third-party vendors who provide research and development, manufacturing, and other services in the ordinary course of business. Some of these contracts are subject to milestone-based invoicing and services are completed over an extended period of time. The Company records liabilities under these contractual commitments when it determines an obligation has been incurred, regardless of the timing of the invoice. This process involves reviewing open contracts and purchase orders, communicating with applicable Company personnel to identify services that have been performed on its behalf and estimating the level of service performed and the associated cost incurred for the service when the Company has not yet been invoiced or otherwise notified of actual cost. The majority of service providers invoice the Company monthly in arrears for services performed. The Company makes estimates of accrued expenses as of each balance sheet date in its financial statements based on the facts and circumstances. The Company periodically confirms the accuracy of its estimates with the service providers and makes adjustments if necessary. Examples of estimated accrued expenses include:&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;table cellspacing="0" cellpadding="0" style="; border-collapse: collapse; font-size: 10pt; width: 700px;"&gt;       &lt;tr&gt;     &lt;td style="width: 5%"&gt;&amp;nbsp;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 2%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;&amp;#x2022;&lt;/div&gt;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 1%"&gt;&amp;nbsp;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 92%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;fees paid to Clinical Research Organizations (&amp;#x201c;CROs&amp;#x201d;) in connection with preclinical and toxicology studies and clinical trials;&lt;/div&gt;&lt;/td&gt;    &lt;/tr&gt;     &lt;/table&gt;  &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;table cellspacing="0" cellpadding="0" style="; border-collapse: collapse; font-size: 10pt; width: 700px;"&gt;       &lt;tr&gt;     &lt;td style="width: 5%"&gt;&amp;nbsp;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 2%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;&amp;#x2022;&lt;/div&gt;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 1%"&gt;&amp;nbsp;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 92%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;fees paid to investigative sites in connection with clinical trials;&lt;/div&gt;&lt;/td&gt;    &lt;/tr&gt;     &lt;/table&gt;  &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;table cellspacing="0" cellpadding="0" style="; border-collapse: collapse; font-size: 10pt; width: 700px;"&gt;       &lt;tr&gt;     &lt;td style="width: 5%"&gt;&amp;nbsp;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 2%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;&amp;#x2022;&lt;/div&gt;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 1%"&gt;&amp;nbsp;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 92%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;fees paid to contract manufacturers in connection with the production of our raw materials, drug substance and drug products;&amp;nbsp;and&lt;/div&gt;&lt;/td&gt;    &lt;/tr&gt;     &lt;/table&gt;  &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;table cellspacing="0" cellpadding="0" style="; border-collapse: collapse; font-size: 10pt; width: 700px;"&gt;       &lt;tr&gt;     &lt;td style="width: 5%"&gt;&amp;nbsp;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 2%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;&amp;#x2022;&lt;/div&gt;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 1%"&gt;&amp;nbsp;&lt;/td&gt;     &lt;td style="vertical-align: top; width: 92%"&gt;&lt;div style="display: inline; font-size: 10pt"&gt;professional fees.&lt;/div&gt;&lt;/td&gt;    &lt;/tr&gt;     &lt;/table&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Company bases its expenses related to clinical trials on its estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and CROs that conduct and manage clinical trials on the Company&amp;#x2019;s behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, the Company estimates the time period over which services will be performed and the level of effort expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company will adjust the accrual accordingly. As of June 30, 2015 and December 31, 2014, the carrying value of accrued expenses approximates their fair value due to their short-term settlement.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Income Taxes&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The liability method is used in the Company&amp;#x2019;s accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;/div&gt;&lt;/div&gt;  &lt;!-- Field: Page; Sequence: 9; Value: 3 --&gt;      &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; margin: 0 0 0 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Accumulated Other Comprehensive Income (Loss)&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Accumulated other comprehensive income (loss) is comprised of unrealized gains and losses on investments available-for-sale and is disclosed as a separate component of stockholders&amp;#x2019; equity. Amounts reclassified from accumulated other comprehensive income (loss) are recorded as interest and other income on the Consolidated Statements of Comprehensive Income (Loss). During the six months ended June 30, 2015, realized gains of $12 were reclassified out of accumulated other comprehensive income (loss). No reclassifications out of accumulated other comprehensive income (loss) were recorded during the six months ended June 30, 2014.&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Revenue Recognition&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;The Company recognizes revenues from collaborative and other research and development arrangements, royalties and product sales when realized or realizable and earned. Revenue is realized or realizable and earned when all of the following criteria are met: (i)&amp;nbsp;persuasive evidence of an arrangement exists; (ii)&amp;nbsp;delivery has occurred or services have been rendered; (iii)&amp;nbsp;the seller&amp;#x2019;s price to the buyer is fixed or determinable; and (iv)&amp;nbsp;collectability is reasonably assured.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Collaborative and Other Research and Development Arrangements and Royalties&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Revenue from license fees, royalty payments, event payments, and research and development fees are recognized as revenue when the earnings process is complete and the Company has no further continuing performance obligations or the Company has completed the performance obligations under the terms of the agreement. Fees received under licensing agreements that are related to future performance are deferred and recognized over an estimated period determined by management based on the terms of the agreement and the products licensed. Revisions to revenue or profit estimates as a result of changes in the estimated revenue period are recognized prospectively.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Under certain of the Company&amp;#x2019;s license agreements, the Company receives royalty payments based upon its licensees&amp;#x2019; net sales of covered products. The Company recognizes royalty revenues when it can reliably estimate such amounts and collectability is reasonably assured.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;For arrangements that involve the delivery of more than one element, each product, service and/or right to use assets is evaluated to determine whether it qualifies as a separate unit of accounting. This determination is based on whether the deliverable has &amp;#x201c;stand-alone value&amp;#x201d; to the customer. The consideration that is fixed or determinable is then allocated to each separate unit of accounting based on the relative selling price of each deliverable. The estimated selling price of each deliverable is determined using the following hierarchy of values: (i) vendor-specific objective evidence of fair value, (ii) third-party evidence of selling price (&amp;#x201c;TPE&amp;#x201d;) and (iii) best estimate of selling price (&amp;#x201c;BESP&amp;#x201d;). The BESP reflects our best estimate of what the selling price would be if the deliverable was regularly sold by the Company on a stand-alone basis. In most cases the Company expects to use TPE or BESP for allocating consideration to each deliverable. The consideration allocated to each unit of accounting is recognized as the related goods or services are delivered, limited to the consideration that is not contingent upon future deliverables. Analyzing the arrangement to identify deliverables requires the use of judgment, and each deliverable may be an obligation to deliver services, a right or license to use an asset, or another performance obligation.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;In June 2015, the Company entered into a License Agreement (the &amp;#x201c;Agreement&amp;#x201d;) granting CSL Limited (&amp;#x201c;CSL&amp;#x201d;) and its affiliates worldwide rights, excluding Israel, Japan, Korea and Taiwan, to develop, manufacture and commercialize RAPIVAB. The Agreement provides for various types of payments, including a non-refundable upfront fee, milestone payments, and future royalties. Analysis of the Agreement identified three deliverables: (i) license rights, (ii) inventory and (iii) regulatory support to obtain Canadian and European Union (&amp;#x201c;EU&amp;#x201d;) marketing approvals. The Company received an upfront payment of $33,740 from CSL of which $7,000 was determined to be contingent upon EU marketing approval and will be deferred until that time. Approximately $21,777 of the upfront payment was allocated to the license rights and recognized as revenue in the current quarter. Approximately $3,740 of the upfront payment was allocated to the pending sale of inventory and was deferred. This deferred revenue will be recognized when the inventory transfer is complete. Approximately $1,223 of this revenue will be recognized over the expected period of involvement in these regulatory support activities.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Milestone payments are recognized as licensing revenue upon the achievement of specified milestones if (i) the milestone is substantive in nature and the achievement of the milestone was not reasonably assured at the inception of the agreement; and (ii) the fees are non-refundable. Any milestone payments received prior to satisfying these revenue recognition criteria are recorded as deferred revenue.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Under the terms of the Agreement, the Company may receive up to $12,000 in additional payments related to the successful achievement of regulatory milestones, including marketing approval (i) by the FDA for a pediatric indication, (ii) by the EMA for an adult indication in the European Union and (iii) by Health Canada for an adult indication in Canada. The Company evaluated each event based payment under the provisions of ASU 2010-17, &lt;div style="display: inline; font-style: italic;"&gt;Milestone Method of Revenue Recognition&lt;/div&gt;, and determined that each event based payment met the criteria to be considered substantive and represents a milestone under the milestone method of accounting. No event based payments were achieved during the periods presented.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Reimbursements received for direct out-of-pocket expenses related to research and development costs are recorded as revenue in the Consolidated Statements of Comprehensive Income (Loss) rather than as a reduction in expenses. Under the Company&amp;#x2019;s contracts with the Biomedical Advanced Research and Development Authority within the United States Department of Health and Human Services (&amp;#x201d;BARDA/HHS&amp;#x201d;) and the National Institute of Allergy and Infectious Diseases (&amp;#x201c;NIAID/HHS&amp;#x201d;), revenue is recognized as reimbursable direct and indirect costs are incurred.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: left; margin-top: 0pt; margin-right: 0; margin-bottom: 0pt"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&lt;/div&gt;  &lt;!-- Field: Page; Sequence: 10; Value: 3 --&gt;      &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 20pt; text-align: left"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Product Sales&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 20pt; text-align: left"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;The Company recognizes revenue for sales of RAPIVAB when title and substantially all the risks and rewards of ownership have transferred to the customer, which generally occurs on the date of shipment from our specialty distributors, utilizing the Sell-Through revenue recognition methodology. Product sales are recognized when there is persuasive evidence that an arrangement exists, title has passed, the price is fixed and determinable, and collectability is reasonably assured. Product sales are recognized net of estimated allowances, discounts, sales returns, chargebacks and rebates. In the United States, the Company sells RAPIVAB to specialty distributors, who in turn, sell to physician offices, hospitals and federal, state and commercial health care organizations.&amp;nbsp;With the completion of the CSL worldwide license of RAPIVAB, CSL will be primarily responsible for sales of RAPIVAB other than U.S. Government stockpiling sales and the Company&amp;#x2019;s commercial sales will be minimal.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Sales deductions consist of statutory rebates to state Medicaid, Medicare and other government agencies and sales discounts (including trade discounts and distribution service fees). These deductions are recorded as reductions from revenue from RAPIVAB in the same period as the related sales with estimates of future utilization derived from historical experience adjusted to reflect known changes in the factors that impact such reserves.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Company utilizes data from external sources to help it estimate gross-to-net sales adjustments as they relate to the recognition of revenue for RAPIVAB sold. Externally sourced data includes, but is not limited to, information obtained from specialty distributors with respect to their inventory levels and their sell-through to customers, as well as information from third-party suppliers of market research data to the pharmaceutical industry.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Company accounts for these sales deductions in accordance with authoritative guidance on revenue recognition when consideration is given by a vendor to a customer.&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The Company has categorized and described more fully the following significant sales deductions, all of which involve estimates and judgments, which the Company considers to be critical accounting estimates, and require it to use information from external sources.&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Rebates and Chargebacks&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Statutory rebates to state Medicaid agencies and Medicare are based on statutory discounts to RAPIVAB&amp;#x2019;s selling price.&amp;nbsp;As it can take up to nine months or more for information to be received on actual usage of RAPIVAB in Medicaid and other governmental programs, the Company maintains reserves for amounts payable under these programs relating to RAPIVAB sales.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Chargebacks claimed by specialty distributors are based on the differentials between product acquisition prices paid by the specialty distributors and lower government contract pricing paid by eligible customers covered under federally qualified programs.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;The amount of the reserve for rebates and chargebacks is based on multiple qualitative and quantitative factors, including the historical and projected utilization levels, historical payment experience, changes in statutory laws and interpretations as well as contractual terms, product pricing (both normal selling prices and statutory or negotiated prices), changes in prescription demand patterns and utilization of the Company&amp;#x2019;s product through public benefit plans, and the levels of RAPIVAB inventory in the distribution channel. The Company acquires prescription utilization data from third-party suppliers of market research data to the pharmaceutical industry. The Company updates its estimates and assumptions each period and records any necessary adjustments to its reserves. Settlements of rebates and chargebacks typically occur within nine months from point of sale. To the extent actual rebates and chargebacks differ from the Company&amp;#x2019;s estimates, additional reserves may be required or reserves may need to be reversed, either of which would impact current period product revenue.&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Discounts and Sales Incentives&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Discounts and other sales incentives primarily consist of Inventory Management Agreement (&amp;#x201c;IMA&amp;#x201d;) Fees. Per contractual agreements with the Company&amp;#x2019;s specialty distributors, the Company provides an IMA fee based on a percentage of their purchases of RAPIVAB. The IMA fee rates are set forth in individual contracts. The Company tracks sales to these distributors each period and accrues a liability relating to the unpaid portion of these fees by applying the contractual rates to such product sales.&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline;

text-indent: 27pt; margin: 0pt 0"&gt;The Company does not record a product return allowance as it does not offer the ability to return goods once a bonafide shipment has been accepted by a specialty distributor.&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline;

text-indent: 27pt; margin: 0pt 0"&gt;The Company engages in very limited distribution and direct-response advertising when promoting RAPIVAB.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt;

Research and development expenses include all direct and indirect development costs related to the development of the Company&amp;#x2019;s portfolio of product candidates. Advance payments for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts are recognized as expense when the related goods are delivered or the related services are performed. Research and development expenses include, among other items, personnel costs, including salaries and benefits, manufacturing costs, clinical, regulatory, and toxicology services performed by CROs, materials and supplies, and overhead allocations consisting of various administrative and facilities related costs. Most of the Company&amp;#x2019;s manufacturing and clinical and preclinical studies are performed by third-party CROs. Costs for studies performed by CROs are accrued by the Company over the service periods specified in the contracts and estimates are adjusted, if required, based upon the Company&amp;#x2019;s on-going review of the level of services actually performed.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Additionally, the Company has license agreements with third parties, such as Albert Einstein College of Medicine of Yeshiva University (&amp;#x201c;AECOM&amp;#x201d;), Industrial Research, Ltd. (&amp;#x201c;IRL&amp;#x201d;), and the University of Alabama at Birmingham (&amp;#x201c;UAB&amp;#x201d;), which require fees related to sublicense agreements or maintenance fees. The Company expenses sublicense payments as incurred unless they are related to revenues that have been deferred, in which case the expenses are deferred and recognized over the related revenue recognition period. The Company expenses maintenance payments as incurred.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Deferred collaboration expenses represent sub-license payments, paid to the Company&amp;#x2019;s academic partners upon receipt of consideration from various commercial partners, and other consideration paid to our academic partners for modification to existing license agreements. These deferred expenses would not have been incurred without receipt of such payments or modifications from the Company&amp;#x2019;s commercial partners and are being expensed in proportion to the related revenue being recognized. The Company believes that this accounting treatment appropriately matches expenses with the associated revenue.&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Stock-Based Compensation&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;All share-based payments, including grants of stock option awards and restricted stock unit awards, are recognized in the Company&amp;#x2019;s Consolidated Statements of Comprehensive Income (Loss) based on their fair values. The fair value of stock option awards is estimated using the Black-Scholes option pricing model. The fair value of restricted stock unit awards is based on the grant date closing price of the common stock. Stock-based compensation cost is recognized as expense on a straight-line basis over the requisite service period of the award. In addition, we have outstanding performance-based stock options for which no compensation expense is recognized until &amp;#x201c;performance&amp;#x201d; has occurred.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Interest Expense and Deferred Financing Costs&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;Interest expense for the three months ended June&amp;nbsp;30, 2015 and 2014 was $1,306 and $1,225, respectively, and for the six months ended June 30, 2015 and 2014 was $2,621 and $2,467, respectively, and relates to the issuance of the PhaRMA Notes (defined in Note 4). Costs directly associated with the issuance of the PhaRMA Notes have been capitalized and are included in other current assets on the Consolidated Balance Sheets. These costs are being amortized to interest expense over the term of the PhaRMA Notes using the effective interest rate method. Amortization of deferred financing costs included in interest expense was $110 for each of the three months ended June&amp;nbsp;30, 2015 and 2014, and $220 for each of the six months ended June&amp;nbsp;30, 2015 and 2014.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;/div&gt;  &lt;!-- Field: Page; Sequence: 12; Value: 3 --&gt;      &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Currency Hedge Agreement&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.5in; margin: 0 0 10pt"&gt;In connection with the issuance by Royalty Sub of the PhaRMA Notes, the Company entered into a Currency Hedge Agreement (defined in Note 4) to hedge certain risks associated with changes in the value of the Japanese yen relative to the U.S. dollar. The Currency Hedge Agreement does not qualify for hedge accounting treatment; therefore, mark-to-market adjustments are recognized in the Company&amp;#x2019;s Consolidated Statements of Comprehensive Income (Loss). Cumulative mark-to-market adjustments for the six months ended June 30, 2015 and 2014 resulted in losses of $332 and $3,350, respectively. Mark-to-market adjustments are determined by a third party pricing model that uses quoted prices in markets that are not actively traded and for which significant inputs are observable directly or indirectly, representing Level 2 in the fair value hierarchy as defined by U.S. GAAP. In addition, the Company realized a currency exchange gain of $1,545 during the first six months of 2015 associated with the exercise of a U.S. Dollar/Japanese yen currency option.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;The Company is also required to post collateral in connection with the mark-to-market adjustments based on thresholds defined in the Currency Hedge Agreement. As of June 30, 2015 and December 31, 2014, no hedge collateral was posted under the agreement.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Net Income (Loss) Per Share&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Net income (loss) per share is based upon the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is equivalent to basic net income (loss) per share for all periods presented herein, except for the three months ended June 30, 2015 for which diluted income per share is $0.06 and basic income per share is $0.07 per share.&lt;/div&gt;

Actual results could differ from those estimates.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 0.25in; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 0.25in; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Significant Customers and Other Risks&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;The Company relies primarily on three specialty distributors to purchase and supply the majority of RAPIVAB. These three pharmaceutical specialty distributors accounted for greater than 90% of all RAPIVAB product sales to date and accounted for predominantly all of the Company&amp;#x2019;s outstanding receivables from product sales. The loss of one or more of these specialty distributors as a customer could negatively impact the commercialization of RAPIVAB. However, the Company will utilize these specialty distributors on a limited basis subsequent to the CSL transaction as CSL will be responsible for commercial sales on a worldwide basis with the exception of Israel, Japan, Korea and Taiwan.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0"&gt;The Company&amp;#x2019;s primary source of revenue that has an underlying cash flow stream is the reimbursement of RAPIVAB (i.e., peramivir) and BCX4430 development expenses, which was earned under cost-plus-fixed-fee contracts with BARDA/HHS and NIAID/HHS, respectively. The Company relies on BARDA/HHS and NIAID/HHS to reimburse predominantly all of the development costs for its RAPIVAB and BCX4430 programs. Accordingly, reimbursement of these expenses represents a significant portion of the Company&amp;#x2019;s collaborative and other research and development revenues. The completion, as with the June 30, 2014 BARDA/HHS peramivir development contract, or termination of the NIAID/HHS and BARDA/HHS BCX4430 programs/collaboration could negatively impact the Company&amp;#x2019;s future Consolidated Statements of Comprehensive Income (Loss) and Cash Flows. In addition, the Company also recognizes royalty revenue from the net sales of RAPIACTA; however, the underlying cash flow from these royalty payments goes directly to pay the interest, and then the principal, on the Company&amp;#x2019;s non-recourse notes payable. Payment of the interest and the ultimate repayment of principal of these notes will be entirely funded by future royalty payments derived from net sales of RAPIACTA. The Company&amp;#x2019;s drug development activities are performed by a limited group of third party vendors. If any of these vendors were unable to perform their services, this could significantly impact the Company&amp;#x2019;s ability to complete its drug development activities.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 27pt"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Risks from Third Party Manufacturing and Distribution Concentration&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 27pt; margin: 0pt 0"&gt;The Company relies on single source manufacturers for active pharmaceutical ingredient and finished product manufacturing of RAPIVAB. Additionally, the Company relies upon a single third party to provide warehousing and distribution services for RAPIVAB. Delays in the manufacture or distribution of any product could adversely impact the commercial revenue and future procurement stockpiling of RAPIVAB.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Credit Risk&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;Cash equivalents and investments are financial instruments which potentially subject the Company to concentration of risk to the extent recorded on the Consolidated Balance Sheets. The Company deposits excess cash with major financial institutions in the United States. Balances may exceed the amount of insurance provided on such deposits. The Company believes it has established guidelines for investment of its excess cash relative to diversification and maturities that maintain safety and liquidity. To minimize the exposure due to adverse shifts in interest rates, the Company maintains a portfolio of investments with an average maturity of approximately 18 months or less. Other than product sale receivables discussed above, the majority of the Company&amp;#x2019;s receivables from collaborations are due from the U.S. Government, for which there is no assumed credit risk.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt;  &lt;!-- Field: Page; Sequence: 13; Value: 3 --&gt;      &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Recent Accounting Pronouncements&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;In April 2015, the FASB issued ASU No. 2015-03, &lt;div style="display: inline; font-style: italic;"&gt;Simplifying the Presentation of Debt Issuance Costs&lt;/div&gt;. This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company does not expect this ASU will have a material impact on its consolidated financial statements.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 27pt; margin: 0pt 0"&gt;In May 2014, the FASB issued ASU 2014-09 &amp;#x2013; &lt;div style="display: inline; font-style: italic;"&gt;Revenue from Contracts with Customers&lt;/div&gt;, which provides a single, comprehensive revenue recognition model for all contracts with customers. The core principal of this ASU is that an entity should recognize revenue when it transfers 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 ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In July 2015, the FASB finalized a one year delay in the effective date of this standard, which will now be effective January 1, 2018, however early adoption is permitted any time after the original effective date, January 1, 2017. Companies can transition to the new standard under the full retrospective method or the modified retrospective method. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.&lt;/div&gt;&lt;/div&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>
