Summary of significant accounting policies	'
	1. Summary of significant accounting policies
	Basis of presentation and consolidation
	The accompanying unaudited consolidated financial statements include the accounts of Emergent BioSolutions Inc. (the "Company" or "Emergent") and its wholly-owned and majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
	The unaudited consolidated financial statements included herein have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X issued by the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the SEC.
	In the opinion of the Company's management, any adjustments contained in the accompanying unaudited consolidated financial statements are of a normal recurring nature, and are necessary to present fairly the financial position of the Company as of June 30, 2014; the results of operations and comprehensive income (loss) for the three and six months ended June 30, 2014 and 2013; and cash flows for the six months ended June 30, 2014 and 2013. Interim results are not necessarily indicative of results that may be expected for any other interim period or for an entire year.
	There have been no significant changes to the Company's summary of significant accounting policies, contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the SEC, during the six months ended June 30, 2014, except for additions to the Company's accounting policies for revenue recognition and inventories related to the Cangene Corporation ("Cangene") acquisition (see Note 2).
	Revenue recognition
	The Company recognizes revenues from product sales if four basic criteria have been met:
	§	there is persuasive evidence of an arrangement;
	§	delivery has occurred or title has passed to the Company's customer;
	§	the fee is fixed or determinable; and
	§	collectability is reasonably assured.
	All revenues from product sales are recorded net of applicable allowances for sales returns, rebates, special promotional programs, and discounts. The Company estimates allowances for deductions from revenue using a combination of information received from third parties including market data, inventory reports from major wholesalers, historical information and analysis. These estimates are subject to the inherent limitations of estimates that rely on third party data, as certain third- party information may itself rely on estimates and reflect other limitations. Provisions for estimated rebates and other allowances, such as discounts and promotional and other credits, are estimated based on historical payment experience, historical relationship to revenues, estimated customer inventory levels and contract terms, and actual discounts offered. Management believes that such provisions are determinable because of the limited number of assumptions involved and the consistency of historical experience.
	The Company markets and sells its Biosciences products through commercial wholesalers (direct customers) who purchase the products at a price referred to as the wholesale acquisition cost ("WAC"). Additionally, the Company enters into agreements with indirect customers for a contracted price that is less than the WAC. The indirect customers, such as group-purchasing organizations, physician practice-management groups and hospitals, purchase the Company's products from the wholesalers. Under these agreements with the wholesalers, the Company guarantees that it will credit them for the difference between the WAC and the indirect customers' contracted price. This credit is referred to as a chargeback. Wholesalers provide detailed information regarding indirect customer purchases as part of the justification for their credit request. Once received by the Company, these requests are standardized and tracked within a software system that adjudicates and reconciles all indirect claims coming from wholesalers. The database with these claims is used for historical trending and estimating future indirect sales, which are used to estimate accruals. Adjustments to these provisions are made periodically to reflect new facts and circumstances that may indicate that historical experience may not be indicative of current and/or future results. The Company makes subjective judgments primarily based on its evaluation of current market conditions and trade inventory levels related to the products. This evaluation may result in an increase or decrease in the experience rate that is applied to current and future sales, or as an adjustment to past sales, or both. The Company estimates allowances for revenue-reducing obligations such as rebates, special promotional programs, and discounts, using a combination of historical trends, contractual obligations and information received from third parties. The accuracy of these estimates is dependent upon the inherent limitations of extrapolating estimates from historical trends and upon the quality of the third-party information.
	Inventories
	Inventories are stated at the lower of cost or market with cost being determined using a standard cost method, which approximates average cost. Average cost consists primarily of material, labor and manufacturing overhead expenses (which includes fixed production-overhead costs) and includes the services and products of third party suppliers. The Company analyzes its inventory levels quarterly and writes down, in the applicable period, inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value and inventory in excess of expected customer demand. The Company also writes off, in the applicable period, the costs related to expired inventory. Costs of purchased inventories are recorded using weighted-average costing. The Company determines normal capacity for each production facility and allocates fixed production-overhead costs on that basis. Any excess, unallocated fixed production-overhead costs are expensed as incurred.

	2. Acquisitions
	Cangene Corporation
	On February 21, 2014, the Company acquired 100% of the voting interest of Cangene for $3.24 per share in cash (on a fully-diluted basis), which represents a total purchase price of $221.8 million. This transaction was accounted for by the Company under the acquisition method of accounting, with the Company as the acquirer. Under the acquisition method of accounting, the assets and liabilities of Cangene were recorded as of the acquisition date, at their respective fair values, and combined with those of the Company. This acquisition diversifies the product portfolio of the Company's Biodefense and Biosciences divisions and expands the Company's manufacturing capabilities.
	The table below summarizes the preliminary allocation of the purchase price based upon estimated fair values of assets acquired and liabilities assumed at February 21, 2014.  As of the date of this filing, the valuation of acquired intangible assets, inventory, deferred taxes, property plant and equipment, employee related liabilities and other fair value adjustments are not complete as the Company is obtaining and analyizing additional information related to the aformentioned items.  As such, the purchase price allocation is subject to change.
	(in thousands)	21-Feb-14
	Fair value of tangible assets acquired and liabilities assumed:
	Cash	$	43,631
	Accounts receivable		19,940
	Inventory (i)		52,619
	Prepaid expenses and other assets		2,375
	Property, plant and equipment		40,264
	Deferred taxes, net		18,371
	Income tax receivable		2,940
	Accounts payable and accrued liabilities		(22,916	)
	Provision for chargebacks		(3,940	)
	Contingent purchase consideration		(5,776	)
	Deferred revenue		(6,378	)
	Total fair value of tangible assets acquired and liabilities assumed		141,130
	Acquired in-process research and development		8,500
	Acquired intangible assets		40,400
	Goodwill		31,770
	Total purchase price	$	221,800
	(i) Acquired inventory reflects a $6.2 million adjustment to record inventory at fair value, referred to as a step-up adjustment. The $6.2 million step-up was estimated to be amortized through cost of product sales and contract manufacturing over the next five years based on estimated inventory turnover, which will increase cost of product sales and contract manufacturing during such period.
	The table below summarizes the preliminary estimated fair value of intangible assets acquired and the estimated amortization periods:
					Amortization
					Period
	( in thousands)	Amount			in years
	Corporate Trade Name	$	2,800			5
	Marketed Products		8,300			10
	Licensed Products		3,300			7
	Biodefense Products		20,400			12
	Contract Manufacturing		5,600			8
	Total identified intangible assets	$	40,400
	The Company determined the estimated fair value of the intangible assets using the income approach, which is based on the present value of future cash flows. The fair value measurements are based on significant unobservable inputs that are developed by the Company using estimates and assumptions of the respective market and market penetration of the Company's products.
	A substantial portion of the assets acquired from Cangene consisted of intangible assets. The Marketed Products intangible asset includes WinRho® SDF [Rho(D) Immune Globulin Intravenous (Human)] and VARIZIG® (Varicella Zoster Immune Globulin (Human). The Licensed Products intangible asset includes HepaGam B® (Hepatitis B Immune Globulin Intravenous (Human)) and episil® (oral liguid). The Biodefense intangible asset includes BATTM [Botulism Antitoxin Heptavalent (A, B, C, D, E, F, G)-Equine], AIGIV (Anthrax Immune Globulin Intravenous (Human)) and VIGIV (Vaccinia Immune Globulin Intravenous (Human)). The Contract Manufacturing intangible asset is primarily related to contract manufacturing in Baltimore, Maryland.
	The Company estimated the fair value of the Marketed, Licensed and Biodefense Product intangible assets using the income approach with a present value discount rate of 15%, which is based on the estimated weighted-average cost of capital for companies with profiles substantially similar to that of Cangene. This is comparable to the estimated internal rate of return for the acquisition and represents the rate that market participants would use to value these intangible assets. The projected cash flows from these Marketed, Licensed and Biodefense Product intangible assets were based on key assumptions including: estimates of revenues and operating profits; the life of the potential commercialized product and associated risks; and risks related to the viability of and potential alternative treatments in any future target markets.
	The Company estimated the fair value of the Contract Manufacturing intangible asset using the income approach with a present value discount rate of 15%, which is based on the estimated weighted-average cost of capital for companies with profiles substantially similar to that of Cangene. This is comparable to the estimated internal rate of return for the acquisition and represents the rate that market participants would use to value this intangible asset. The projected cash flows from the Contract Manufacturing intangible asset was based on key assumptions including: estimates of revenues and operating profits; and viability of attaining/maintaining future third-party manufacturing relationships with the Company's customers.
	The Company estimated the fair value of the Corporate Trade Name intangible asset using the relief of royalty method with a present value discount rate of 15%, which is based on the estimated weighted-average cost of capital for companies with profiles substantially similar to that of Cangene. This is comparable to the estimated internal rate of return for the acquisition and represents the rate that market participants would use to value this intangible asset.
	The weighted average amortization period of the intangible assets is 118 months. For the three and six months ended June 30, 2014, the Company recorded amortization expense of $1.1 million and $1.5 million, respectively, for intangible assets acquired from Cangene, which has been recorded in cost of product sales and contract manufacturing. Amortization expense of $691,000 and $928,000, respectively, was recorded within the Biosciences segment for the three and six months ended June 30, 2014. Amoritization expense of $389,000 and $602,000, respectively, was recorded within the Biodefense segement for the three and six months ended June 30, 2014.
	The intangible asset associated with in-process research and development ("IPR&D") acquired from Cangene is the IXINITY product candidate. Management determined that the estimated acquisition-date fair value of intangible assets related to IPR&D was  $8.5 million. The estimated fair value was determined using the income approach, which discounts expected future cash flows to present value. The Company estimated the fair value using a present value discount rate of 16%, which is based on the estimated weighted-average cost of capital for companies with profiles substantially similar to that of Cangene. This is comparable to the estimated internal rate of return for the acquisition and represents the rate that market participants would use to value the IPR&D. The projected cash flows for IXINITYwas based on key assumptions including: estimates of revenues and operating profits related to IXINITY, considering its stage of development on the acquisition date; the time and resources needed to complete the development and approval of the product candidate; the life of the potential commercialized product and associated risks, including the inherent difficulties and uncertainties in developing a product candidate such as obtaining marketing approval from the FDA and other regulatory agencies; and risks related to the viability of and potential alternative treatments in any future target markets. IPR&D assets are considered to be indefinite-lived until the completion or abandonment of the associated research and development efforts (see Note 5).
	The Company recorded approximately $31.8 million in goodwill related to the Cangene acquisition, representing the purchase price paid in the acquisition that was in excess of the fair value of the tangible and intangible assets acquired. None of the goodwill generated from the Cangene acquisition is expected to be deductible for tax purposes.
	The Company has incurred transaction costs related to the Cangene acquisition of approximately $3.7 million for the six months ended June 30, 2014, which has been recorded in selling, general and administrative expenses within the Company's Biosciences segment. The Company has incurred to date a total of  $7.0 million in transaction costs associated with the Cangene acquisition through June 30, 2014, of which $3.3 million was incurred in 2013.
	The following pro forma information is presented as if the acquisition had occurred on January 1, 2013, and combines the historical results of operations of the Company and Cangene for the six month periods ended June 30, 2014 and 2013.
		June 30,
	(in thousands)	2014			2013

	Pro forma net loss	$	(17,782	)	$	(3,838	)
	Healthcare Protective Products Division
	On August 1, 2013, the Company acquired substantially all of the assets and liabilities of Health Protective Products Division ("HPPD"), a division of Bracco Diagnostics Inc. ("Bracco"), for $25.9 million in cash along with contingent purchase consideration obligations to Bracco. The assets and liabilities acquired include HPPD's product, RSDL, and a majority of the customer and distributor agreements associated with RSDL along with $1.5 million of manufacturing equipment. In addition, the Company assumed a $1.5 million liability associated with the Canadian Technology Development Fund. The acquisition diversifies the product portfolio of the Biodefense segment by adding product sales from RSDL.
	The contingent purchase consideration obligation due to Bracco is based on a percentage of RSDL net sales, ranging from 5-10%, for the period August 1, 2013 through July 31, 2028. At August 1, 2013, the contingent purchase consideration obligation was recorded at a fair value of $16.2 million. The Level 3 fair value of this obligation is based on management's assessment of the potential future realization of the contingent purchase consideration payments. This assessment is based on inputs that have no observable market. The obligation is measured using the income approach (a discounted cash flow model).
	The total purchase price is summarized below:
	(in thousands)
	Amount of cash paid to Bracco Diagnostics Inc.	$	25,873
	Fair value of contigent purchase consideration at date of acquisition		16,232
	Total purchase price	$	42,105
	The table below summarizes the allocation of the purchase price based upon fair values of assets acquired and liabilities assumed at August 1, 2013.

	Acquired equipment		1,543
	Other		11
	Assumed liabilities		(1,464	)
	Total purchase price	$	42,105
A substantial portion of the assets acquired from Bracco consisted of intangible assets associated with the RSDL product.  As of the date of acquisition, the Company recorded intangible assets of approximately $28.6 million related to RSDL, which is being amortized over 8 years, and $3.5 million related to a manufacturing agreement with Bracco, which is being amortized over 3 years. For the three and six months ended June 30, 2014, the Company recorded $1.2 million and $2.3 million, respectively, amortization expense for intangible assets acquired from Bracco which was recorded in cost of product sales and contract manufacturing within the Company's Biodefense segment. The weighted average remaining amortization period for the intangible assets is 80 months.
The Company recorded approximately $9.9 million in goodwill related to the HPPD acquisition representing the purchase price paid in the acquisition in excess of the fair value of the tangible and intangible assets acquired. This goodwill is included in the Company's biodefense segment. None of the goodwill generated from the HPPD acquisition is expected to be deductible for tax purposes.
The Company has determined the historical results of HPPD were not significant to the Company's results of operations, and as such no proforma disclosures have been presented.

	For the periods ended June 30, 2014 and 2013, the Company did not have any transfers between Level 1 and Level 2 assets or liabilities.
	The fair value of contingent purchase consideration obligations are based on management's assessment of changes as a result of adjustments to the discount rates and updates in the assumed and actual achievement of net sales for future RSDL, HepaGam B and episil®, which are inputs that have no observable market (Level 3). For the three and six months ended June 30, 2014, the contingent purchase consideration obligation increased by $1.2 million and  $1.6 million, respectively, primarily due to an adjustment to the actual and expected timing of RSDL, HepaGam B and episil® sales. This increase resulted in a charge that is classified in the Company's statement of operations as cost of product sales and contract manufacturing.
	The following table is a reconciliation of the beginning and ending balance of the liabilities measured at fair value using significant unobservable inputs (Level 3) during the six months ended June 30, 2014.

As of June 30, 2014, the Company had no assets or liabilities that were measured at fair value on a nonrecurring basis except for the assts acquired and liabilities assumed as part of the Cangene acquisition (See Note 2). As of June 30, 2013, the Company had no assets or liabilities that were measured at fair value on a nonrecurring basis.

	As of June 30, 2014, the Company had $50.3 million of IPR&D assets, which are included in the Biosciences business segment. This includes $41.8 million related to the Company's otlertuzumab product candidate and $8.5 million related to the Company's IXINITY product candidate. On July 29, 2014, the U.S. Food and Drug Administration ("FDA") issued a complete response letter for the New Drug Application ("NDA") of IXINITY. The complete response letter requested additional analyses of data from completed studies and noted deficiencies in the chemistry, manufacturing, and controls section of the license application, all of which must be resolved before approval can be granted by FDA. The Company determined that the FDA's response to its NDA is a potential indicator of impairment of the related IXINITY IPR&D asset. However, the Company has not yet completed its interim impairment assesment. The Company has determined the potential range of impairment could be from zero to the carrying value of the IXINITY IPR&D asset.

Long-term debt	'
	6. Long-term debt
	On January 29, 2014, the Company issued $250.0 million aggregate principal amount of 2.875% Convertible Senior Notes due 2021 (the "Notes"). The Notes bear interest at a rate of 2.875% per year, payable semi-annually in arrears on January 15 and July 15 of each year, commencing July 15, 2014. The Notes mature on January 15, 2021, unless earlier purchased by the Company, redeemed or converted. The conversion rate is equal to 30.8821 shares of common stock per $1,000 principal amount of notes (which is equivalent to an initial conversion price of approximately $32.38 per share of common stock). The conversion rate is subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. The Company incurred approximately $8.3 million in debt issuance costs associated with the Notes, which has been capitalized on the consolidated balance sheets and is being amortized over seven years, using the effective interest method.
	On December 11, 2013, the Company entered into a senior secured credit agreement (the "Credit Agreement") with three lending financial institutions (the "Lenders"), led by Bank of America, N.A., as administrative agent. The Credit Agreement originally provided for a revolving credit facility of up to $100 million through December 11, 2018 (or such earlier date required by the terms of the Credit Agreement) and a term loan facility of up to $125 million to be drawn in full, if at all, on or prior to March 31, 2014. In connection with the Credit Agreement, the Company borrowed $62.0 million under the revolving credit facility primarily to repay obligations under existing loan agreements. On January 29, 2014, in connection with the Company's issuance of the Notes, the unused $125 million term loan portion of the Credit Agreement terminated automatically in accordance with the terms of the Credit Agreement. In addition, following the closing of the Notes offering, the Company repaid the $62.0 million outstanding indebtedness under the revolving credit facility, which restored the full $100 million revolving credit capacity under this facility. In addition, during the six months ended June 30, 2014, the Company expensed $1.8 million of debt issuance cost associated with the term loan facility.  As of June 30, 2014, no amounts were drawn under the revolving credit facility.
	The Company's payment obligations under the Credit Agreement are secured by a lien on substantially all of the Company's assets, including the stock of all of the Company's subsidiaries, and the assets of the subsidiary guarantors, including mortgages over certain of their real properties, including the Company's large-scale vaccine manufacturing facility in Lansing, Michigan and the Company's product development and manufacturing facility in Baltimore, Maryland.
	The Credit Agreement, as amended, contains affirmative and negative covenants customary for financings of this type. Negative covenants in the Credit Agreement limit the Company's ability to, among other things: incur indebtedness (other than the issuance of the Notes) and liens; dispose of assets; make investments including loans, advances or guarantees; and enter into certain mergers or similar transactions. The Credit Agreement also contains financial covenants, tested quarterly and in connection with any triggering events under the Credit Agreement that include the maintenance of: (1) a minimum consolidated debt service coverage ratio of 2.50 to 1.00, (2) a maximum consolidated leverage ratio for the period ending on or prior to September 30, 2014 of 4.00 to 1.00, for the measurement period ending December 31, 2014 of 3.75 to 1.00, and thereafter of 3.50 to 1.00, (3) a maximum consolidated senior leverage ratio of 2.00 to 1.00 (when no term loan is outstanding) and (4) a minimum liquidity requirement of $50 million. Upon the occurrence and continuance of an event of default under the Credit Agreement, the commitments of the lenders to make loans under the Credit Agreement may be terminated and the Company's payment obligations under the Credit Agreement may be accelerated. The events of default under the Credit Agreement include, among others, subject in some cases to specified cure periods: payment defaults; inaccuracy of representations and warranties in any material respect; defaults in the observance or performance of covenants; bankruptcy and insolvency related defaults; the entry of a final judgment in excess of a threshold amount; change of control; and the invalidity of loan documents relating to the Credit Agreement.

	As of June 30, 2014, the Company had two stock-based employee compensation plans, the Third Amended and Restated Emergent BioSolutions Inc. 2006 Stock Incentive Plan (the "2006 Plan") and the Emergent BioSolutions Employee Stock Option Plan (the "2004 Plan") (together, the "Emergent Plans").
	On May 22, 2014, the Company's shareholders approved an amendment to the 2006 Plan, which increased the number of shares of common stock available for issuance under plan awards by 4,000,000.  As part of this amendment, awards of restricted stock units after May 22, 2014 are counted against the maximum aggregate number of shares of common stock available for issuance under the 2006 Plan as 2.3 shares of common stock for every one restricted stock unit granted. The maximum number of shares subject to awards that may be granted per year under the 2006 Plan to a single participant is 1,000,000.

Earnings per share	'
	9. Earnings per share
	For the three and six month periods ended June 30, 2014 and 2013, basic earnings per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period.
	For the three and six month periods ended June 30, 2014, diluted earnings per share is computed using the if-converted method by dividing the adjusted net income (loss) by the weighted average number of shares of common stock outstanding during the period. The adjusted net income (loss) is adjusted for interest expense and amortization of debt issuance cost, both net of tax, associated with the Company's Notes. The weighted average number of shares-diluted is adjusted for the potential dilutive effect of the exercise of stock options and the vesting of restricted stock units along with the assumption of the conversion of the convertible obligations, at the beginning of the period.
	For the three and six months ended June 30, 2013, diluted earnings per share is computed using the treasury method by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period, adjusted for the potential dilutive effect of other securities if such securities were converted or exercised.
	The following table presents the calculation of basic and diluted net income (loss) per share:

	Income (loss) per share-diluted	$	0.13	$	0.29	$	(0.41	)	$	0.07
	For the three months ended June 30, 2014 there were no adjustments to adjusted net income (loss) or dilutive securities associated with the Company's Notes as such adjustments would have been anti-dilutive. For the six months ended June 30, 2014, outstanding stock options to purchase approximately 5,100,000.0 million shares of common stock, along with 8.1 million shares related to the Company's convertible debt, were excluded from the calculation of diluted earnings per share because of the adjusted net loss incurred for the six months ended June 30, 2014 would make these awards anti-dilutive.
	Stock options with exercise prices in excess of the average per share closing price during the period are not considered in the calculation of fully diluted earnings per share. For the three months ended June 30, 2014, approximately 1.5 million were excluded from the calculation of diluted earnings per share. For the three and six month periods ended June 30, 2013, approximately 3.5 million and 2.7 million stock options were excluded from the calculation of diluted earnings per share.

Segment information	'
	10. Segment information
	For financial reporting purposes, the Company reports financial information for two business segments: Biodefense and Biosciences. The Company's two business segments, or divisions, engage in business activities for which discrete financial information and allocation resources are reviewed by the chief operating decision maker. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. The Company's reportable segments are business units that offer different products and product candidates and are managed separately because they manufacture and develop distinct products with different manufacturing and development processes, along with having seperate and distinct sales and marketing processes.
	The Biodefense division is a specialty biopharmaceutical business focused on countermeasures that address Chemical, Biological, Radiological and Nuclear ("CBRN") threats and consists of two business units: vaccines and therapeutics, and medical devices. Revenues in this segment are primarily from sales of the Company's FDA-licensed product, BioThrax® (Anthrax Vaccine Adsorbed), to the U.S. government. The Biosciences division is directed to commercial opportunities and primarily targets hematology/oncology, transplantation and infectious diseases, and consists of two business units, therapeutics and vaccines. The "All Other" segment relates to the general operating costs of the Company and includes costs of the centralized services departments, which are not allocated to the other segments, as well as spending on activities that are not classified as Biodefense or Biosciences.

	Basis of presentation and consolidation
	The accompanying unaudited consolidated financial statements include the accounts of Emergent BioSolutions Inc. (the "Company" or "Emergent") and its wholly-owned and majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
	The unaudited consolidated financial statements included herein have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X issued by the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the SEC.
	In the opinion of the Company's management, any adjustments contained in the accompanying unaudited consolidated financial statements are of a normal recurring nature, and are necessary to present fairly the financial position of the Company as of June 30, 2014; the results of operations and comprehensive income (loss) for the three and six months ended June 30, 2014 and 2013; and cash flows for the six months ended June 30, 2014 and 2013. Interim results are not necessarily indicative of results that may be expected for any other interim period or for an entire year.
	There have been no significant changes to the Company's summary of significant accounting policies, contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the SEC, during the six months ended June 30, 2014, except for additions to the Company's accounting policies for revenue recognition and inventories related to the Cangene Corporation ("Cangene") acquisition (see Note 2).
Revenue recognition	'
	Revenue recognition
	The Company recognizes revenues from product sales if four basic criteria have been met:
	§	there is persuasive evidence of an arrangement;
	§	delivery has occurred or title has passed to the Company's customer;
	§	the fee is fixed or determinable; and
	§	collectability is reasonably assured.
	All revenues from product sales are recorded net of applicable allowances for sales returns, rebates, special promotional programs, and discounts. The Company estimates allowances for deductions from revenue using a combination of information received from third parties including market data, inventory reports from major wholesalers, historical information and analysis. These estimates are subject to the inherent limitations of estimates that rely on third party data, as certain third- party information may itself rely on estimates and reflect other limitations. Provisions for estimated rebates and other allowances, such as discounts and promotional and other credits, are estimated based on historical payment experience, historical relationship to revenues, estimated customer inventory levels and contract terms, and actual discounts offered. Management believes that such provisions are determinable because of the limited number of assumptions involved and the consistency of historical experience.
	The Company markets and sells its Biosciences products through commercial wholesalers (direct customers) who purchase the products at a price referred to as the wholesale acquisition cost ("WAC"). Additionally, the Company enters into agreements with indirect customers for a contracted price that is less than the WAC. The indirect customers, such as group-purchasing organizations, physician practice-management groups and hospitals, purchase the Company's products from the wholesalers. Under these agreements with the wholesalers, the Company guarantees that it will credit them for the difference between the WAC and the indirect customers' contracted price. This credit is referred to as a chargeback. Wholesalers provide detailed information regarding indirect customer purchases as part of the justification for their credit request. Once received by the Company, these requests are standardized and tracked within a software system that adjudicates and reconciles all indirect claims coming from wholesalers. The database with these claims is used for historical trending and estimating future indirect sales, which are used to estimate accruals. Adjustments to these provisions are made periodically to reflect new facts and circumstances that may indicate that historical experience may not be indicative of current and/or future results. The Company makes subjective judgments primarily based on its evaluation of current market conditions and trade inventory levels related to the products. This evaluation may result in an increase or decrease in the experience rate that is applied to current and future sales, or as an adjustment to past sales, or both. The Company estimates allowances for revenue-reducing obligations such as rebates, special promotional programs, and discounts, using a combination of historical trends, contractual obligations and information received from third parties. The accuracy of these estimates is dependent upon the inherent limitations of extrapolating estimates from historical trends and upon the quality of the third-party information.
Inventories	'
	Inventories
	Inventories are stated at the lower of cost or market with cost being determined using a standard cost method, which approximates average cost. Average cost consists primarily of material, labor and manufacturing overhead expenses (which includes fixed production-overhead costs) and includes the services and products of third party suppliers. The Company analyzes its inventory levels quarterly and writes down, in the applicable period, inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value and inventory in excess of expected customer demand. The Company also writes off, in the applicable period, the costs related to expired inventory. Costs of purchased inventories are recorded using weighted-average costing. The Company determines normal capacity for each production facility and allocates fixed production-overhead costs on that basis. Any excess, unallocated fixed production-overhead costs are expensed as incurred.

Option Award Activity	'
	As of June 30, 2014, the Company had two stock-based employee compensation plans, the Third Amended and Restated Emergent BioSolutions Inc. 2006 Stock Incentive Plan (the "2006 Plan") and the Emergent BioSolutions Employee Stock Option Plan (the "2004 Plan") (together, the "Emergent Plans").
	On May 22, 2014, the Company's shareholders approved an amendment to the 2006 Plan, which increased the number of shares of common stock available for issuance under plan awards by 4,000,000.  As part of this amendment, awards of restricted stock units after May 22, 2014 are counted against the maximum aggregate number of shares of common stock available for issuance under the 2006 Plan as 2.3 shares of common stock for every one restricted stock unit granted. The maximum number of shares subject to awards that may be granted per year under the 2006 Plan to a single participant is 1,000,000.
	The following is a summary of stock option award activity under the Emergent Plans:
		2006 Plan					2004 Plan

Earnings per share [Abstract]	'
Summary of Basic and Diluted Net Income per Share	'
	For the three and six month periods ended June 30, 2014 and 2013, basic earnings per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period.
	For the three and six month periods ended June 30, 2014, diluted earnings per share is computed using the if-converted method by dividing the adjusted net income (loss) by the weighted average number of shares of common stock outstanding during the period. The adjusted net income (loss) is adjusted for interest expense and amortization of debt issuance cost, both net of tax, associated with the Company's Notes. The weighted average number of shares-diluted is adjusted for the potential dilutive effect of the exercise of stock options and the vesting of restricted stock units along with the assumption of the conversion of the convertible obligations, at the beginning of the period.
	For the three and six months ended June 30, 2013, diluted earnings per share is computed using the treasury method by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period, adjusted for the potential dilutive effect of other securities if such securities were converted or exercised.
	The following table presents the calculation of basic and diluted net income (loss) per share:
		Three Months Ended June 30,				Six Months Ended June 30,

Acquired inventory reflects a $6.2 million adjustment to record inventory at fair value, referred to as a step-up adjustment. The $6.2 million step-up was estimated to be amortized through cost of product sales and contract manufacturing over the next five years based on estimated inventory turnover, which will increase costs of product sales and contract manufacturing during such period.
