Company Overview [Abstract]

Company Overview

NOTE 1 COMPANY OVERVIEW

We are a biopharmaceutical company that has focused on the development of vaccines addressing unmet medical needs, including nicotine addiction. We have sought to leverage our experience and knowledge in powering the human immune system to target these serious unmet medical needs. We have been incorporated in Delaware since 1969 and our operations are located in Rockville, Maryland.

Our sole remaining product currently in development is NicVAX^® [Nicotine Conjugate Vaccine], an innovative and proprietary investigational vaccine for the treatment of nicotine addiction and prevention of smoking relapse based on patented technology. We suffered a significant setback in 2011 when NicVAX did not achieve the primary endpoint in two Phase III efficacy trials conducted in the U.S. As of March 31, 2012, our remaining assets include the following: (i) $94.9 million of cash and cash equivalents, (ii) the potential residual value of NicVAX as well as any next-generation nicotine vaccine which was licensed to GlaxoSmithKline Biologicals S.A. (GSK) in 2010, (iii) the potential royalty from Phoslyra which was sold to Fresenius USA Manufacturing, Inc. (Fresenius) in 2006, and (iv) the potential value of our net operating losses (NOLs).

Merger Agreement with Biota Holdings Limited. On April 22, 2012, we entered into a merger implementation agreement (Merger Agreement) with Biota Holdings Limited, a Melbourne, Australia company (Biota), pursuant to which, among other things, Nabi and Biota will undertake a business combination under Australian corporate law such that each ordinary share of Biota capital stock will be exchanged for newly issued shares of Nabi common stock, and Biota will become a wholly-owned subsidiary of Nabi (the Merger). In connection with the Merger, Nabi will change its name to "Biota Pharmaceuticals, Inc." but will remain listed on the NASDAQ Stock Market as its sole stock exchange listing and be headquartered in the United States.

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger:

•

Each Biota share outstanding immediately prior to the effective time will be transferred to Nabi in exchange for 0.669212231 Nabi shares (as such amount may be adjusted pursuant to the terms of the Merger Agreement). Immediately after the closing of the Merger, the Nabi shares issued to former Biota stockholders will represent approximately 74% of Nabi's outstanding common stock, and the shares of common stock held by current Nabi stockholders will represent approximately 26% of Nabi's outstanding common stock;

•

The board of directors of Nabi will consist of six Biota directors and two Nabi directors; and

•

Biota's current Chief Executive Officer and Chief Financial Officer are expected to serve as the Chief Executive Officer and Chief Financial Officer, respectively, of Nabi until the appointment of new U.S.—based management.

Prior to the closing of the Merger Agreement, subject to the terms and conditions of the Merger Agreement:

•

Nabi intends to return to Nabi's stockholders excess cash above $54 million (which is required to be delivered to the combined company), after satisfying and reserving for outstanding liabilities, through a dividend, return of capital or repurchase of outstanding Nabi shares, or a combination thereof. We currently estimate the amount of cash to be returned to Nabi stockholders to be in the range of $25 to 30 million; and

•

Nabi plans to distribute to its stockholders contingent value rights providing certain payment rights arising from cash received by Nabi from a future sale, transfer, license or similar transaction involving our NicVAX program assets.

Consummation of the Merger is subject to customary conditions for a business combination of this type under Australian and Delaware corporate law, including, among others, (i) approval of the Merger by the stockholders of Biota in accordance with applicable Australian law, (ii) the affirmative vote of the holders of a majority of the issued and outstanding Nabi shares at a meeting of stockholders (the Nabi Shareholder Meeting) approving amendments to the certificate of incorporation of Nabi to (a) increase the number of authorized Nabi Shares to 200,000,000, principally to allow for the issuance of additional Nabi Shares to pay the Merger consideration, and (b) change the name of Nabi to "Biota Pharmaceuticals, Inc.," and (iii) the affirmative vote of the holders of a majority of the votes cast at the Nabi stockholder meeting approving issuance of new Nabi shares to Biota stockholders in the Merger, as required by the rules of the NASDAQ Stock Market.

Each party's obligation to consummate the Merger is subject to certain other conditions, including approval of the Merger by the Supreme Court of Victoria, Australia, the expiration or early termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and certain other competition laws, the absence of any injunction, restraint or governmental restriction making illegal or restraining the consummation of the transactions contemplated by the Merger Agreement, the accuracy of the other party's representations and warranties contained in the Merger Agreement that are qualified as to materiality, the accuracy in all material respects of the other party's representations and warranties contained in the Merger Agreement that are not qualified as to materiality, the other party's performance in all material respects of all obligations to be performed by it under the Merger Agreement, and the absence of any effect, event, occurrence or matter that has had or would reasonably be expected to have, individually or in the aggregate, a material adverse effect on the other party of the nature specified in the Merger Agreement. In addition, Biota's obligation to consummate the Merger is subject to receiving a certificate from Nabi showing that Nabi has a closing net cash balance of no less than $54 million, calculated in accordance with the terms of the Merger Agreement, and the appointment of specified Biota directors to the Nabi board of directors effective as of the closing of the Merger. The parties expect to close the Merger in the third quarter of 2012 subject to satisfaction of these and other closing conditions.

NicVAX Agreement with GSK. In March 2010, we closed an exclusive worldwide option and licensing agreement with GSK for NicVAX as well as for the development of follow-on nicotine addiction vaccines. Upon closing, we received a $40 million initial payment. Under the terms of the agreement, we granted to GSK (i) an option to obtain an exclusive worldwide license to develop, commercialize and manufacture NicVAX as it currently exists, as well as certain potential alternative forms of NicVAX together with an adjuvant other than a GSK proprietary adjuvant and/or with different presentation, dosage or administration (NicVAX Alternatives), and (ii) an exclusive worldwide license to develop, commercialize and manufacture certain future generation candidate vaccines for the prevention or treatment of nicotine addiction based on our NicVAX intellectual property (other than NicVAX and NicVAX Alternatives). During the quarter, GSK informed us that it does not intend to exercise the NicVAX option due to the failure of the Phase III trials to achieve their primary end points. However, GSK has not indicated that it has terminated the development of the future generation nicotine vaccine.

Notwithstanding the failure to achieve the primary endpoint in our two Phase III trials, if the future generation nicotine vaccine being developed by GSK is successful, GSK will pay us up to a total of $290 million in contingent milestone payments as follows: (i) up to $47 million based on Phase II and Phase III clinical trial-related milestones, (ii) up to $34 million based on obtaining regulatory approval in certain major market countries, and (iii) up to a total of $209 million based on tiered annual sales of future generation candidates. GSK also will pay us royalty payments on annual net sales of future generation candidates, beginning at 5% and potentially increasing on incremental sales to as high as 7%, with the increase depending on whether annual net sales of future generation candidates meet or exceed specified annual sales targets in any calendar year ranging from $300 million to $600 million.

PentaStaph Sale to GSK. In November 2009, we sold our PentaStaph product candidate and related assets to GSK under an Asset Purchase Agreement for a total consideration of $46 million including a $20 million up-front payment and $26 million payable upon achievement of certain milestones, all of which we have received. During the second quarter of 2011 we completed our work to help develop PentaStaph under contract with GSK.

PhosLo. In 2006, we sold certain assets related to our PhosLo operations to Fresenius. Under the sale agreement, we are entitled to additional contingent milestone payments of $2.5 million upon approval of a new indication for PhosLo and royalties of up to $65.0 million on annual sales of Phoslyra, a new formulation of PhosLo, over a base amount of $32 million for 10 years after the November 14, 2006 closing date. To date, annual sales of Phoslyra have not exceeded the base amount, and we have not recognized any royalty revenue from those sales.

Basis Of Presentation And Summary Of Significant Accounting Policies [Abstract]
Basis Of Presentation And Summary Of Significant Accounting Policies	NOTE 2 BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES In the opinion of management, the accompanying condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly our financial position, results of operations and cash flows. The condensed consolidated balance sheet at December 31, 2011, has been derived from audited consolidated financial statements as of that date. The interim results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain information and footnote disclosure normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to instructions, rules and regulations prescribed by the U.S. Securities and Exchange Commission. We believe that the disclosures provided herein are adequate to make the information presented not misleading when these condensed consolidated financial statements are read in conjunction with the Consolidated Financial Statements and Notes included in our Annual Report on Form 10-K for the year ended December 31, 2011, filed with the Securities and Exchange Commission. Principles of consolidation: The condensed consolidated financial statements include the accounts of Nabi Biopharmaceuticals and our wholly-owned subsidiaries (referred to as "Nabi," the "Company," "us," or "we" throughout this report). All significant inter-company accounts and transactions are eliminated in consolidation. All of our wholly-owned subsidiaries are dormant or are otherwise non-operative. Accounting estimates: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period, including such amounts related to discontinued operations. Actual results could differ from those estimates. Fiscal year periods: Historically, our fiscal year ended on the last Saturday of December. Consequently, we periodically had a 53-week fiscal year. In 2012, we amended our By-Laws to change our fiscal year end to a calendar basis; this prospective change did not have a material impact on our financial condition and results of operations for any periods presented. Financial instruments: The carrying amounts of financial instruments including cash equivalents, marketable securities, accounts receivable and accounts payable approximated fair value as of March 31, 2012 and December 31, 2011, because of the relatively short-term maturity of these instruments. Cash, cash equivalents and marketable securities: Cash equivalents consist of investments in low risk, highly liquid securities with original maturities of 90 days or less. Marketable securities consist of low risk fixed income investment instruments such as government obligations, government agency and Federal Deposit Insurance Corporation backed notes with maturities typically less than eighteen months. Marketable securities are classified as available-for-sale and recorded at fair value; unrealized gains and losses on those securities are reflected in other comprehensive income (loss). We assess the risk of impairment related to securities held in our investment portfolio on a regular basis and noted no "permanent" or "other than temporary" impairment during the first quarter of 2012. Our investment policies and procedures are reviewed periodically by management and our audit committee to minimize credit risk. Concentration of credit risk: Financial instruments that potentially subject us to credit and liquidity risk consist primarily of cash, marketable securities and receivables. The Company maintains cash deposits at major financial institutions with high credit quality. The Company's operating accounts exceeded the Federal Deposit Insurance Corporation limits of $250,000. Cash equivalents primarily consist of short-term money market funds, which are deposited with reputable financial institutions. At December 31, 2011, the Company's marketable investments consist primarily of United States government agency securities as well as corporate debt securities and commercial paper. The Company's investment policy limits investments to only investment-grade securities with the objective to preserve principal and maintain sufficient liquidity to meet operational objectives. The Company's receivables are with one customer, who has a history of paying timely. The Company's receivables are expected to be collected. Revenue recognition: Our revenue generating arrangements may include multiple elements and deliverables, including licenses, options, research and development activities, participation on joint steering committees and contract manufacturing, among other elements. When we determine that an element has stand-alone value to our customer, we allocate a portion of the total contract price to that element based on its relative selling price, determined pursuant to a selling price hierarchy, and recognize revenue for that element according to its characteristics. Revenue consists of license fees, milestone payments, and payments for contractual services. License fees received that do not have stand-alone value are initially recorded as deferred revenue, and are subsequently recognized as revenue ratably over the period of our participation on joint steering committees. The joint steering committee established in connection with our option and license agreement with GSK related to NicVAX is currently expected to operate for 190 months from the date of the agreement (or through December 2025). Our efforts under the joint steering committee established in connection with our asset purchase agreement with GSK related to PentaStaph were completed in the second quarter of 2011. For milestones that are deemed substantive, we recognize the contingent revenue when: (i) the milestones have been achieved; (ii) no further performance obligations with respect to the milestones exist; and (iii) collection is reasonably assured. A milestone is considered substantive if all of the following conditions are met: (i) the milestone is nonrefundable; (ii) achievement of the milestone was not reasonably assured at the inception of the arrangement; (iii) substantive effort is involved to achieve the milestone; and (iv) the amount of the milestone appears reasonable in relation to the effort expended with the other milestones in the arrangement and the related risk associated with achievement of the milestone. If a milestone is deemed not to be substantive, the Company would recognize the portion of the milestone payment as revenue that correlates to work already performed; the remaining portion of the milestone payment will be deferred and recognized as revenue as the Company completes its performance obligations. Payments for contractual services are recognized as revenue when earned, typically when the services are rendered. We analyze cost reimbursable grants and contracts to determine whether we should report such reimbursements as revenue or as an offset to research and development expenses incurred. Collaborative arrangements: We are an active participant with exposure to significant risks and rewards of commercialization relating to the development of NicVAX and future generation nicotine vaccines based on NicVAX technology. For costs incurred and revenues generated from third parties where we are deemed to be the principal participant, we recognize revenues and costs using the gross basis of accounting; otherwise we use the net basis of accounting. Research and development expenses: Research and development costs are expensed as incurred; advanced payments are deferred and subsequently expensed over the period of performance. Research and development expenses include direct labor costs as well as the costs of contractors and other direct and indirect expenses (including an allocation of the costs of facilities). We expense amounts payable to third parties under collaborative product development agreements at the earlier of the milestone achievement or as payments become contractually due. In the first quarter 2011 we recorded approximately $0.3 million of cost reimbursements from government grants as an offset to research and development expenses. Income (loss) per share: Basic income (loss) per share is computed by dividing consolidated net income (loss) available to common shareholders by the weighted-average number of common shares outstanding during the period. For periods of net income when the effects are dilutive, diluted earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of shares outstanding and the dilutive impact of all dilutive potential common shares. Dilutive potential common shares consist primarily of stock options. The dilutive impact of dilutive potential common shares resulting from stock options is determined by applying the treasury stock method. For all periods of net loss, diluted loss per share is calculated similarly to basic loss per share because the impact of all dilutive potential common shares is anti-dilutive due to the net losses; accordingly, diluted loss per share is the same as basic loss per share. The Company's unvested restricted shares contain non-forfeitable rights to dividends, and therefore are considered to be participating securities; the calculation of basic and diluted income per share excludes net income attributable to the unvested restricted shares from the numerator and excludes the impact of the shares from the denominator. Because of our net income in the first quarter of 2011, the computation of diluted income per share differed from the computation of basic income per share as a result of a (i) numerator adjustment for net income allocated to participating securities and (ii) denominator adjustment related to stock options using the treasury stock method. For the quarters ended March 31, 2012 and March 26, 2011, approximately 4.0 million potentially dilutive shares have been excluded in the calculation of diluted net loss per share, respectively, as their inclusion would be anti-dilutive. Share-based compensation: We expense the estimated fair value of share-based awards made in exchange for employee services over the requisite employee service period. Share-based compensation cost for stock options is determined at the grant date using an option pricing model; share-based compensation cost for restricted stock is determined at the grant date based on the closing price of our common stock on that date. The value of the award that is ultimately expected to vest is recognized as expense on a straight-line basis over the employee's requisite service period. Income taxes: We account for income taxes using the asset and liability approach, which requires, among other things, recognition of future tax benefits and liabilities measured at enacted rates attributable to temporary differences between financial statement and income tax bases of assets and liabilities and to tax net operating loss carryforwards to the extent that realization of these benefits is more likely than not. For interim periods, we recognize an income tax provision (benefit) based on an estimated annual effective tax rate expected for the entire year. We periodically evaluate the realizability of our net deferred tax assets; a valuation allowance is established when the Company believes that it is more likely than not that its deferred tax assets will not be realized. Changes in valuation allowances from period to period are included in the Company's tax provision in the period of change. We recognize a tax benefit from uncertain tax positions only if it is "more likely than not" that the position is sustainable based on its technical merits, and our policy is to recognize interest and penalties on uncertain tax positions as a component of income tax expense. We consider discontinued operations for purposes of determining the amount of tax benefits that result from a loss from continuing operations. Segment information: We currently operate in a single business segment. Recent accounting standards: In June 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2011-05, Presentation of Comprehensive Income. ASU 2011-05 revises the manner in which entities present comprehensive income in their financial statements. The new guidance removes the presentation options in Accounting Standards Codification 220 and requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. ASU 2011-05 did not change the items that must be reported in other comprehensive income. The Company adopted the provisions of ASU 2011-05 in the first quarter of 2012. As the Company's net income (loss) was the same as comprehensive income (loss), the Company did not include a statement of comprehensive income (loss). New accounting pronouncements: We have evaluated all Accounting Standards Updates through the date the financial statements were issued and believe the adoption of these will not have a material impact to our results of operations or financial position.

Gains and losses on available-for-sale marketable securities are based on the specific identification method. The contractual maturities of all of our available-for-sale investments as of December 31, 2011 were less than 12 months.

- Definition

Tabular disclosure of available-for-sale securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt.

Discontinued Operations	3 Months Ended
Discontinued Operations	Mar. 31, 2012
Discontinued Operations [Abstract]
Discontinued Operations	NOTE 4 DISCONTINUED OPERATIONS During 2006, we assessed our pricing programs under Medicare/Medicaid and other governmental pricing programs for the period from 2002 through the second quarter of 2006. In connection with the 2006 review, we identified additional liabilities related to discontinued operations for possible overbilling under Medicare/Medicaid and other governmental pricing programs. The estimated liability related to these programs was approximately $1.7 million at December 31, 2011. In the first quarter 2012, we undertook an assessment of the remaining liabilities and concluded that these remaining liabilities should be eliminated after determining that any remaining obligations related to the programs were not material.

- Definition

The entire disclosure for the facts and circumstances leading to the completed or expected disposal, manner and timing of disposal, the gain (loss) recognized in the income statement and the income statement caption that includes that gain (loss), amounts of revenues and pretax profit or loss reported in discontinued operations, the segment in which the disposal group was reported, and the classification (whether sold or classified as held for sale) and carrying value of the assets and liabilities comprising the disposal group. Includes all disposal groups, including those classified as components of the entity (discontinued operations).

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2012
Income Taxes [Abstract]
Income Taxes	NOTE 5 INCOME TAXES We file income tax returns in the U.S., with various states and foreign jurisdictions, and are subject to tax audits in all jurisdictions for which we file tax returns. Tax audits by their very nature are often complex and can require several years to complete. As of March 31, 2012, we recorded a valuation allowance against all of our deferred tax assets. Significant judgment is required in evaluating our tax positions and determining our provision for income taxes. We establish accruals for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These accruals are established when we believe that certain positions might be challenged despite our belief that our tax return positions are fully supportable. We adjust these accruals in light of changing facts and circumstances, such as the outcome of a tax audit. Under the tax statute of limitations applicable to the Internal Revenue Code, we are no longer subject to U.S. federal income tax examinations by the Internal Revenue Service for years before 2005. However, because we are carrying forward income tax attributes, such as net operating losses and tax credits from 2002 and earlier tax years, these attributes can still be audited when used on returns filed in the future. Under the statutes of limitation applicable to most state income tax laws, we are no longer subject to state income tax examinations by tax authorities for years before 2005 in states in which we have filed income tax returns. Certain states may take the position that we are subject to income tax in such states even though we have not filed income tax returns in such states and, depending on the varying state income tax statutes and administrative practices, the statute of limitations in such states may extend to years before 2005. We are subject to foreign tax examinations by tax authorities for all years of operation.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Fair Value Disclosures

Fair Value Disclosures [Abstract]

Fair Value Disclosures

NOTE 6 FAIR VALUE DISCLOSURES

We follow a three-tier fair value hierarchy which prioritizes the inputs used in measuring the fair value of our assets and liabilities. These tiers include (i) Level 1, defined as observable inputs such as quoted prices in active markets for identical assets; (ii) Level 2, defined as observable inputs other than Level 1 prices such as quoted prices for similar assets, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and (iii) Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. All cash and cash equivalents, as well as available-for-sale marketable securities, are recorded at fair value at March 31, 2012 and December 31, 2011. The inputs used in measuring the fair value of these instruments are considered to be Level 1 and Level 2 in accordance with the three-tier fair value hierarchy.

The inputs used in measuring the fair value of cash and cash equivalents are considered to be Level 1 in accordance with the three-tier fair value hierarchy and the fair values are based on period-end statements supplied by the various banks and brokers. The majority of our funds were deposited in institutional money market mutual funds with the remainder held in regular interest bearing and non-interest bearing depository accounts with commercial banks.

The inputs used in measuring the fair value of our available-for-sale marketable securities at December 31, 2011 (none at March 31, 2012) are considered to be Level 2 in accordance with the three-tier fair value hierarchy. These securities are valued using a multi-dimensional pricing model that includes a variety of inputs, including quoted prices for similar assets and liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. To assess the fair value of these securities, we obtain fair values from an independent third-party valuation service provider. As we are responsible for the determination of fair value, we review the values provided by the independent third-party valuation service provider for reasonableness, which could include reviewing other publicly available information.


December 31, 2011			Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
(In thousands)	Total		Level 1		Level 2		Level 3
Government-sponsored securities	$	993	$	—	$	993	$	—
Corporate debt securities		1,086		721		365	$	—

Total securities	$	2,079	$	721	$	1,358	$	—

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Licenses And Royalty Arrangements [Abstract]
Licenses And Royalty Arrangements	NOTE 8 LICENSES AND ROYALTY ARRANGEMENTS We have entered into licenses and royalty agreements for our products in development. PentaStaph: In November 2009, we sold our PentaStaph product candidate and related assets to GSK under an Asset Purchase Agreement for a total consideration of $46 million including a $20 million up-front payment and $26 million payable upon achievement of certain milestones, all of which we have received. During the second quarter of 2011 we completed our work to help develop PentaStaph under contract with GSK. NicVAX: In March 2010, we closed an exclusive worldwide option and licensing agreement with GSK for NicVAX as well as for the development of follow-on nicotine addiction vaccines. Upon closing, we received a $40 million initial payment. Under the terms of the agreement, we granted to GSK (i) an option to obtain an exclusive worldwide license to develop, commercialize and manufacture NicVAX as it currently exists, as well as certain potential alternative forms of NicVAX together with an adjuvant other than a GSK proprietary adjuvant and/or with different presentation, dosage or administration (NicVAX Alternatives), and (ii) an exclusive worldwide license to develop, commercialize and manufacture certain future generation candidate vaccines for the prevention or treatment of nicotine addiction based on our NicVAX intellectual property (other than NicVAX and NicVAX Alternatives). During the quarter, GSK informed us that it does not intend to exercise the NicVAX option due to the failure of the Phase III trials to achieve their primary end points. However, GSK has not indicated that it terminated the development of the future generation nicotine vaccine. Notwithstanding the failure to achieve the primary endpoint in our two Phase III trials, if the future generation nicotine vaccine being developed by GSK is successful, GSK will pay us up to a total of $290 million in contingent milestone payments as follows: (i) up to $47 million based on Phase II and Phase III clinical trial-related milestones, (ii) up to $34 million based on obtaining regulatory approval in certain major market countries, and (iii) up to a total of $209 million based on tiered annual sales of future generation candidates. GSK also will pay us royalty payments on annual net sales of future generation candidates, beginning at 5% and potentially increasing on incremental sales to as high as 7%, with the increase depending on whether annual net sales of future generation candidates meet or exceed specified annual sales targets in any calendar year ranging from $300 million to $600 million. We believe all future milestones under the NicVAX agreement to be substantive as they are at risk until achieved. The probability of us receiving future contingent milestones is uncertain as it is based on the achievement of various success-based development and regulatory approvals contingent upon the occurrence of various future events, most of which have a high degree of uncertainty of occurring. Revenue under the NicVAX agreement consists of license fees, milestone payments, and payments for contractual services. License fees received are initially recorded as deferred revenue, and are subsequently recognized as revenue ratably over the period of our participation on joint steering committees. The joint steering committee related to the NicVAX agreement is currently expected to operate for 190 months from the date of the agreement (or through December 2025).

NOL Rights Agreement [Abstract]
NOL Rights Agreement	NOTE 9 NOL RIGHTS AGREEMENT On August 25, 2011, our Board of Directors adopted a stockholder Rights Agreement with American Stock Transfer & Trust Company, LLC, as rights agent, in an effort to prevent an "ownership change" under Section 382 from occurring and thereby protect the value of our net operating losses. Under the Rights Agreement, the Board of Directors declared a non-taxable dividend of one preferred share purchase right for each outstanding share of common stock to be distributed to stockholders of record on August 25, 2011. Concurrent with the signing of the Merger Agreement with Biota, Nabi and the rights agent amended the Rights Agreement to terminate the rights under the Rights Agreement.

Commitments And Contingencies [Abstract]
Commitments And Contingencies	NOTE 10 COMMITMENTS AND CONTINGENCIES We have agreements with our employees that include certain cash payments and equity-based award modifications in the event of a termination of employment or a change in control of the Company. We are parties to legal proceedings that we believe to be ordinary, routine litigation incidental to the business of present or former operations. It is management's opinion, based on the advice of counsel, that the ultimate resolution of such litigation will not have a material adverse effect on our financial condition, results of operations or cash flows.
