Basis of Presentation and Significant Accounting Policies [Text Block]

1. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. The financial statements include all adjustments (consisting only of normal recurring adjustments) the management of PDL BioPharma, Inc. (the Company, PDL, we, us or our) believes are necessary for a fair presentation of the periods presented. These interim financial results are not necessarily indicative of results expected for the full fiscal year or for any subsequent interim period.

The accompanying Condensed Consolidated Financial Statements and related financial information should be read in conjunction with the audited Consolidated Financial Statements and the related notes thereto for the year ended December 31, 2011, included in our Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission. The Condensed Consolidated Balance Sheet at December 31, 2011, has been derived from the audited Consolidated Financial Statements at that date.

Principles of Consolidation

The Consolidated Financial Statements include the accounts of PDL and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.

Notes Receivable

We account for our notes receivable at amortized cost, net of unamortized origination fees, if any. Related fees and costs are recorded net of amounts reimbursed. Interest is accreted or accrued to interest income using the interest method.

Customer Concentration

The percentage of total revenue earned from our licensees’ net product sales, which individually accounted for ten percent or more of our total revenues, was:

		Three Months Ended September 30,						Nine Months Ended September 30,
Licensee	Product Name	2012			2011			2012			2011
Genentech, Inc. (Genentech)	Avastin®		30	%		28	%		31	%		30	%
	Herceptin®		36	%		38	%		35	%		34	%
	Lucentis®		15	%		15	%		18	%		16	%

Elan Corporation, Plc (Elan)	Tysabri®		14	%		14	%		12	%		11	%

Foreign Currency Hedging

We enter into foreign currency hedges to manage exposures arising in the normal course of business and not for speculative purposes.

We hedge certain Euro-denominated currency exposures related to our licensees’ product sales with Euro forward contracts and, in 2011, Euro forward and option contracts. In general, these contracts are intended to offset the underlying Euro market risk in our royalty revenues. These contracts extend through the fourth quarter of 2014. We designate foreign currency exchange contracts used to hedge royalty revenues based on underlying Euro-denominated sales as cash flow hedges.

At the inception of the hedging relationship and on a quarterly basis, we assess hedge effectiveness. The fair value of the Euro forward contracts is estimated using pricing models with readily observable inputs from actively quoted markets and is disclosed on a gross basis. The aggregate unrealized gain or loss, net of tax, on the effective portion of the hedge is recorded in stockholders’ deficit as accumulated other comprehensive income (loss). Gains or losses on cash flow hedges are recognized as an adjustment to royalty revenue in the same period that the hedged transaction impacts earnings as royalty revenue. Any gain or loss on the ineffective portions is reported in other income in the period the ineffectiveness occurs.

During the third quarter of 2012, we de-designated and terminated a portion of our cash flow hedges. The gain realized was reclassified from other comprehensive income (loss) to other income in the third quarter. See Note 5 for additional information on our foreign currency hedge transactions.

Comprehensive Income

In the first quarter of 2012, we adopted Financial Accounting Standards Board (FASB) accounting standard update (ASU) 2011-05, and have presented the components of other comprehensive income (loss) in the Condensed Consolidated Statements of Comprehensive Income. Also in accordance with this ASU, we have applied this guidance retrospectively to all periods presented. The adoption of the guidance was a change to the presentation of other comprehensive income (loss) and had no effect on our condensed consolidated financial statements. See Note 14 for our discussion of accumulated other comprehensive income (loss).

Recent Accounting Pronouncements

In December 2011, the FASB issued ASU 2011-11 requiring new disclosures associated with offsetting financial instruments and derivative instruments on the balance sheet that will enable users to evaluate the effect on an entity’s financial position. The ASU will be effective in the first quarter of 2013, but is not expected to have a material impact on our financial statements.

Net income per diluted share	$	0.32	$	0.28	$	1.08	$	0.88

We compute net income per basic share using the weighted-average number of shares of common stock outstanding during the period less the weighted-average number of restricted stock shares that are subject to repurchase.

We compute net income per diluted share using the sum of the weighted-average number of common and common equivalent shares outstanding. Common equivalent shares used in the computation of net income per diluted share include shares that may be issued under our stock options and restricted stock awards, our 2.875% Convertible Senior Notes due February 15, 2015 (February 2015 Notes), our 2.875% Series 2012 Convertible Notes due February 15, 2015 (Series 2012 Notes), our 3.75% Senior Convertible Notes due May 1, 2015 (May 2015 Notes) and, in 2011, our 2.00% Convertible Senior Notes due February 15, 2012 (2012 Notes), on a weighted average basis for the period that the notes were outstanding, including the effect of adding back interest expense, net of tax, and the underlying shares using the if-converted method. Our 2012 Notes were fully retired as of September 30, 2011, and $179.0 million aggregate principal amount of our February 2015 Notes was exchanged for our Series 2012 Notes in the first quarter of 2012.

The Series 2012 Notes and May 2015 Notes are net share settled, with the principal amount settled in cash and the excess settled in our common stock. The weighted-average share adjustments related to our Series 2012 Notes and May 2015 Notes include the shares issuable in respect of such excess. The May 2015 Notes had no dilutive effect for the periods ended September 30, 2011. The conversion price of the May 2015 Notes exceeded the market price of our common stock for those periods so no stock was issuable upon conversion.

We excluded 19.2 million and 17.5 million shares of potential dilution for our warrants for the periods ended September 30, 2012 and 2011, respectively, because the exercise price of the warrants exceeded the average market price of our common stock and thus, for the periods presented, no stock was issuable upon conversion. These securities could be dilutive in future periods. Our purchased call options will always be anti-dilutive and therefore 22.6 million and 20.6 million shares were excluded for the periods ended September 30, 2012 and 2011, respectively, because they have no effect on diluted net income per share under GAAP. For further information related to our convertible notes, see Note 9.

We excluded approximately 144,000 and 164,000 shares underlying outstanding stock options, calculated on a weighted average, from our net income per diluted share calculations for the three and nine months ended September 30, 2012, respectively, and approximately 174,000 and 199,000 shares for the three and nine months ended September 30, 2011, respectively, because their effect was anti-dilutive.

Fair Value Disclosures [Text Block]

3. Fair Value Measurements

The fair value of our financial instruments are estimates of the amounts that would be received if we were to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date or exit price. The assets and liabilities are categorized and disclosed in one of the following three categories:

Level 1 – based on quoted market prices in active markets for identical assets and liabilities;

Level 2 – based on quoted market prices for similar assets and liabilities, using observable market based inputs or unobservable market based inputs corroborated by market data; and

Level 3 – based on unobservable inputs using management’s best estimate and assumptions when inputs are unavailable.

The following tables present the fair value of our financial instruments measured at fair value on a recurring basis by level within the valuation hierarchy.

Financial liabilities:
Foreign currency hedge contracts	$	-	$	4,446	$	4,446	$	-	$	9,783	$	9,783

The fair value of the certificate of deposit is priced using quoted market prices for similar instruments, non-binding market prices that are corroborated by observable market data. The certificate of deposit is restricted as it was purchased to collateralize the line of credit for Merus Labs International, Inc., see Note 6.

Corporate debt securities consist primarily of U.S. corporate bonds. The fair value of corporate debt securities is estimated using recently executed transactions or market quoted prices, where observable. Independent pricing sources are also used for valuation.

The fair value of commercial paper is estimated based on observable inputs of comparable securities.

The fair value of foreign currency hedging contracts is estimated based on pricing models using readily observable inputs from actively quoted markets and is disclosed on a gross basis.

The following tables present the fair value of assets and liabilities not subject to fair value recognition by level within the valuation hierarchy:

As of September 30, 2012, the fair values of our Merus Labs Note Receivable, our Senior Secured Note Receivable, and our Other Notes Receivable were determined using one or more discounted cash flow models, incorporating expected payments and the interest rate extended on the notes with fixed interest rates and incorporating expected payments for notes with a variable rate of return.

The fair values of our convertible notes and our Non-recourse Notes, as defined herein, were determined using quoted market pricing or dealer quotes of our then outstanding notes.

4. Cash Equivalents and Investments

As of September 30, 2012 and December 31, 2011, we had invested our excess cash balances primarily in money market funds, corporate debt securities, commercial paper, U.S. government sponsored agency bonds and U.S. treasury securities. Our securities are classified as available-for-sale and are carried at estimated fair value, with unrealized gains and losses, net of estimated taxes, reported in accumulated other comprehensive income (loss) in stockholders’ deficit. See Note 3 for fair value measurement information. The cost of securities sold is based on the specific identification method. To date, we have not experienced credit losses on investments in these instruments and we do not require collateral for our investment activities.

We recognized approximately $11,000 of gains on sales of available-for-sale securities for the three and nine months ended September 30, 2012. No gains or losses on sales of available-for-sale securities were recognized for the periods ended September 30, 2011. No significant facts or circumstances have arisen to indicate that there has been any deterioration in the creditworthiness of the issuers of these securities. Based on our review of these securities, we believe we had no other-than-temporary impairments on these securities as of September 30, 2012 and December 31, 2011.

Note 5 - Foreign Currency Hedging

Derivative Instruments and Hedging Activities Disclosure [Text Block]

5. Foreign Currency Hedging

We designate the foreign currency exchange contracts used to hedge our royalty revenues based on underlying Euro-denominated sales as cash flow hedges. Euro forward contracts are presented on a net basis on our Condensed Consolidated Balance Sheets as we have entered into a netting arrangement with the counterparty. As of September 30, 2012 and December 31, 2011, all outstanding Euro forward contracts and option contracts were classified as cash flow hedges.

In January 2012, we modified our existing Euro forward and option contracts related to our licensees’ sales through December 2012 into Euro forward contracts with more favorable rates. Additionally, we entered into a series of Euro forward contracts covering the quarters in which our licensees’ sales occur through December 2013.

During the third quarter of 2012, we reduced our forecasted exposure to the Euro for 2013 royalties. We de-designated and terminated certain forward contracts, due to our determination that certain cash flow under the de-designated contracts were probable to not occur, and recorded a gain of approximately $391,000 to other income, which was reclassified from other comprehensive income (loss) net of tax effects. The termination of these contracts was effected through a reduction in the notional amount of the original hedge contracts which was then exchanged for new hedges of 2014 Euro-denominated royalties. These 2014 hedges were entered into at a rate more favorable than the market rate as of the date of the exchange.

The notional amounts, Euro exchange rates, fair values of our Euro forward contracts at September 30, 2012, and Euro forward and option contracts at December 31, 2011, designated as cash flow hedges were:

Note 6 - Notes and Other Long-term Receivables

Sep. 30, 2012

Loans, Notes, Trade and Other Receivables Disclosure [Text Block]

6. Notes and Other Long-term Receivables

Notes and other long-term receivables included the following significant agreements:

Merus Labs Note Receivable and Credit Agreement

In July 2012, PDL loaned $35.0 million to Merus Labs International, Inc. (Merus Labs) in connection with its acquisition of a commercial-stage pharmaceutical product and related assets (the Assets). In addition, PDL agreed to provide a $20.0 million letter of credit on behalf of Merus Labs that the seller of the Assets may draw upon to satisfy the remaining $20.0 million purchase price obligation on July 11, 2013 (Letter of Credit). The Letter of Credit is collateralized by a certificate of deposit reflected on our balance sheet as restricted investment. Draws on the Letter of Credit will be funded from the proceeds of an additional loan to Merus Labs. Outstanding borrowings under the July 2012 loan to Merus Labs bear interest at the rate of 13.5% per annum and outstanding borrowings as a result of draws on the Letter of Credit bear interest at the rate of 14.0% per annum, with all interest payable monthly. Merus Labs is required to make annual principal payments of $5.0 million, $7.5 million, $10.0 million, and $12.5 million in 2012, 2013, 2014, and 2015, respectively, with respect of the July 2012 loan. The borrowings are subject to mandatory prepayments upon certain asset dispositions or debt issuances upon the terms set forth in the credit agreement (Credit Agreement).

The Credit Agreement provides for a number of standard events of default, including payment, bankruptcy, covenant, judgment and cross-defaults.

Senior Secured Note Receivable

In March 2012, the Company executed a $7.5 million two-year senior secured note receivable (Senior Secured Note Receivable). In addition to interest, the note gives PDL certain rights to negotiate for certain royalty assets. The note was recorded net of origination fees that are accreted to the note receivable as interest income using the interest method. The note bore interest at 10% per annum, with interest due semi-annually and final interest due at maturity together with the principal.

In August 2012, PDL and the Borrower amended the note receivable, providing a senior secured note receivable of $10.0 million to replace the original $7.5 million note. The principal of the note receivable will be repaid on March 21, 2014. Interest will be paid on the $10.0 million note receivable at a rate of 12% per annum with interest payments due semi-annually in March and September, and final interest due at maturity together with the principal. The note was recorded net of origination fees that are accreted to the note receivable as interest income using the interest method. The Company has not assigned a risk grade to the receivable or recorded an allowance for credit loss as PDL anticipates all payments will be received in full when due. No impairment has been recorded as the payments on the note are current.

For fair value information related to our notes and other long-term receivables, see Note 3.

Legal Proceedings

Communications with Genentech regarding European SPCs

In August 2010, we received a letter from Genentech, sent on behalf of F. Hoffmann-LaRoche Ltd. (Roche) and Novartis AG (Novartis), asserting that Avastin, Herceptin, Lucentis and Xolair® (the Genentech Products) do not infringe the supplementary protection certificates (SPCs) granted to PDL by various countries in Europe for each of the Genentech Products and seeking a response from PDL to these assertions. Genentech did not state what actions, if any, it intends to take with respect to its assertions. PDL’s SPCs were granted by the relevant national patent offices in Europe and specifically cover the Genentech Products. The SPCs covering the Genentech Products effectively extend our European patent protection for our European Patent No. 0 451 216B generally until December 2014, except that the SPCs for Herceptin will generally expire in July 2014.

Genentech’s letter does not suggest that the Genentech Products do not infringe PDL’s U.S. patents to the extent that such Genentech Products are made, used or sold in the United States (U.S.-based Sales). Genentech’s quarterly royalty payments received after receipt of the letter included royalties generated on all worldwide sales of the Genentech Products.

If Genentech is successful in asserting this position, then under the terms of our license agreements with Genentech, it would not owe us royalties on sales of the Genentech Products that are both manufactured and sold outside of the United States. Royalties on sale of the Genentech Products that are made and sold outside of the United States (ex-U.S.-based Manufacturing and Sales) accounted for approximately 35% of our royalty revenues for the nine months ended September 30, 2012. Based on announcements by Roche regarding moving more manufacturing outside of the United States, we expect this amount to increase in the future.

We believe that the SPCs are enforceable against the Genentech Products, that Genentech’s letter violates the terms of the 2003 settlement agreement and that Genentech owes us royalties on sales of the Genentech Products on a worldwide basis. We intend to vigorously assert our SPC-based patent rights.

Nevada Litigation with Genentech, Roche and Novartis in Nevada State Court

In August 2010, we filed a complaint in the Second Judicial District of Nevada, Washoe County, naming Genentech, Roche and Novartis as defendants. We intend to enforce our rights under our 2003 settlement agreement with Genentech and are seeking an order from the court declaring that Genentech is obligated to pay royalties to us on ex-U.S.-based Manufacturing and Sales of the Genentech Products.

The 2003 settlement agreement was entered into as part of a definitive agreement resolving intellectual property disputes between the two companies at that time. The agreement limits Genentech’s ability to challenge infringement of our patent rights and waives Genentech’s right to challenge the validity of our patent rights. Certain breaches of the 2003 settlement agreement as alleged by our complaint require Genentech to pay us liquidated and other damages of potentially greater than one billion dollars. This amount includes a retroactive royalty rate of 3.75% on past U.S.-based Sales of the Genentech Products and interest, among other items. We may also be entitled to either terminate our license agreements with Genentech or be paid a flat royalty of 3.75% on future U.S.-based Sales of the Genentech Products.

In November 2010, Genentech and Roche filed a motion to dismiss our complaint against them in which we seek to enforce our rights under the 2003 settlement agreement with Genentech. Genentech and Roche's motions to dismiss under Nevada Rule of Civil Procedure 12(b)(5) alleged that all of our claims for relief relating to the 2003 settlement agreement should be dismissed because the 2003 settlement agreement applies only to our U.S. patents. In addition, Roche filed a separate motion to dismiss our complaint under Nevada Rule of Civil Procedure 12(b)(2) on the ground that the Nevada court lacks personal jurisdiction over Roche. On July 7, 2011, the Second Judicial District Court of Nevada ruled in favor of us on the two motions to dismiss filed by Genentech and Roche. The court denied Genentech and Roche's motion to dismiss four of our five claims for relief and, further, denied Roche's separate motion to dismiss for lack of personal jurisdiction. The court dismissed one of our claims that Genentech committed a bad-faith breach of the covenant of good faith and fair dealing stating that, based on the current state of the pleadings, no "special relationship" had been established between Genentech and us as required under Nevada law. On November 1, 2011, the Nevada court issued an order accepting Roche’s stipulation of waiver to its personal jurisdiction defense. As a result of the order, Roche is foreclosed from reliance on lack of personal jurisdiction in defending against our claims.

On February 25, 2011, we reached a settlement with Novartis under which, among other things, we agreed to dismiss our claims against Novartis in the action in Nevada state court against Genentech, Roche and Novartis. Genentech and Roche continue to be parties to the Nevada suit.

The court has scheduled trial to commence on October 7, 2013, however this date is likely to be extended. The outcome of this litigation is uncertain and we may not be successful in our allegations.

Lease Guarantee

In connection with the spin-off of Facet Biotech Corporation (Facet) in 2008, we entered into amendments to the leases for our former facilities in Redwood City, California, under which Facet was added as a co-tenant under the leases, and a Co-Tenancy Agreement, under which Facet agreed to indemnify us for all matters related to the leases attributable to the period after the spin-off date. Should Facet default under its lease obligations, we would be held liable by the landlord as a co-tenant and, thus, we have in substance guaranteed the payments under the lease agreements for the Redwood City facilities. As of September 30, 2012, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately $103.0 million. We would also be responsible for lease-related costs including utilities, property taxes and common area maintenance which may be as much as the actual lease payments if Facet were to default. In April 2010, Abbott Laboratories acquired Facet and later renamed the company Abbott Biotherapeutics Corp.

As of September 30, 2012, and December 31, 2011, we had a liability of $10.7 million on our Condensed Consolidated Balance Sheets for the estimated fair value of this guarantee. In future periods, we may increase the recorded liability for this obligation if we conclude that a loss, which is larger than the amount recorded, is both probable and estimable.

Series 2012 Notes

In January 2012, we exchanged $169.0 million aggregate principal of new Series 2012 Notes for an identical principal amount of our February 2015 Notes, plus a cash payment of $5.00 for each $1,000 principal amount tendered, totaling approximately $845,000. The cash incentive payment was allocated to deferred issue costs of $765,000, additional paid-in capital of $52,000 and deferred tax assets of $28,000. The deferred issue costs will be recognized over the life of the Series 2012 Notes as interest expense. In February 2012, we entered into separate privately negotiated exchange agreements under which we exchanged an additional $10.0 million aggregate principal amount of the new Series 2012 Notes for an identical principal amount of our February 2015 Notes. At the conclusion of these transactions, $1.0 million of our February 2015 Notes remained outstanding.

The terms of the Series 2012 Notes are governed by the indenture dated as of January 5, 2012 (Indenture) and include a net share settlement feature, meaning that if a conversion occurs, the principal amount will be settled in cash and the excess, if any, will be settled in the Company’s common stock. The Series 2012 Notes may not be redeemed by the Company prior to their stated maturity date. Our Series 2012 Notes are due February 15, 2015 and bear interest at a rate of 2.875% per annum, payable semi-annually in arrears on February 15 and August 15 of each year. This is the same interest rate that we pay on the February 2015 Notes.

The initial conversion rate of the Series 2012 Notes was 155.396 shares of common stock per $1,000 principal amount, or approximately $6.44 per common share, subject to further adjustment upon certain events including dividend payments. Third party transaction costs of approximately $813,000 related to the exchange transactions have been recognized within general and administrative expense, of which $216,000 was recognized in the first quarter of 2012 and $597,000 was recognized during the year ended December 31, 2011.

Holders may convert their Series 2012 Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the stated maturity date of the Series 2012 Notes under the following circumstances:

During any fiscal quarter commencing after the fiscal quarter ending December 31, 2011, if the closing price of the Company’s common stock for at least 20 trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter exceeds 130% of the conversion price for the Series 2012 Notes on the last day of such preceding fiscal quarter;

During the five business-day period immediately after any five consecutive trading-day period in which the trading price per $1,000 principal amount of the Series 2012 Notes for each trading day of that measurement period was less than 98% of the product of the closing price of the Company’s common stock and the conversion rate for the Series 2012 Notes for that trading day;

Upon the occurrence of certain corporate transactions as provided in the Indenture; or

Anytime, at the holder’s option, beginning on August 15, 2014.

Holders of our Series 2012 Notes who convert their Series 2012 Notes in connection with a fundamental change resulting in the reclassification, conversion, exchange or cancellation of our common stock may be entitled to a make-whole premium in the form of an increase in the conversion rate. Such fundamental change is generally defined to include a merger involving PDL, an acquisition of a majority of PDL’s outstanding common stock and a change of a majority of PDL’s board of directors without the approval of the board of directors.

We allocated $2.3 million of the remaining deferred February 2015 Notes original issue discount as of the date of the exchange to the Series 2012 Notes based on the percentage of the February 2015 Notes exchanged. In accordance with the accounting guidance for convertible debt instruments that may be settled in cash or other assets on conversion, we were required to separately account for the liability component of the instrument in a manner that reflects the market interest rate for a similar nonconvertible instrument at the date of issuance. As a result, we separated the principal balance of the Series 2012 Notes, net of the allocated original issue discount, between the fair value of the debt component and the common stock conversion feature. Using an assumed borrowing rate of 7.3%, which represents the estimated market interest rate for a similar nonconvertible instrument available to us during the period of the exchange transactions, we recorded a total debt discount of $16.8 million, allocated $10.9 million to additional paid-in capital and $5.9 million to deferred tax liability. The discount is being amortized to interest expense over the term of the Series 2012 Notes and increases interest expense during the term of the Series 2012 Notes from the 2.875% cash coupon interest rate to an effective interest rate of 7.3%. The common stock conversion feature is recorded as a component of stockholders’ deficit.

The principal amount, carrying value and unamortized discount of our Series 2012 Notes were:

	September 30, 2012			December 31, 2011

Total	$	3,005	$	-	$	8,881	$	-

As of September 30, 2012, our Series 2012 Notes are convertible into 166.264 shares of the Company’s common stock per $1,000 of principal amount, or approximately $6.01 per common share, subject to further adjustment upon certain events including dividend payments. As of September 30, 2012, the remaining discount amortization period was 2.4 years.

Our common stock price did not exceed the conversion threshold price of $7.98 per common share for at least 20 days during the 30 consecutive trading days ended June 30, 2012; accordingly the Series 2012 Notes were not convertible at the option of the holder during the quarter ended September 30, 2012. Our common stock did not exceed the conversion threshold price of $7.82 for at least 20 days during 30 consecutive trading days ended September 30, 2012; accordingly the Series 2012 Notes are not convertible at the option of the holder during the quarter ending December 31, 2012. At September 30, 2012, the if-converted value of our Series 2012 Notes exceeded their principal amount by approximately $50.2 million.

If a conversion occurs, to the extent that the conversion value exceeds the principal amount, the principal amount is due in cash and the difference between the conversion value and the principal amount is due in shares of the Company’s common stock. As of September 30, 2012, the remaining discount amortization period was 2.6 years.

The principal amount, carrying value and unamortized discount of our May 2015 Notes were:

Our common stock did not exceed the conversion threshold price of $8.94 for at least 20 days during 30 consecutive trading days ended September 30, 2012; accordingly the May 2015 Notes are not convertible at the option of the holder during the quarter ending December 31, 2012. At September 30, 2012, the if-converted value of our May 2015 Notes exceeded their principal amount by approximately $18.7 million.

We may exercise the purchased call options upon conversion of our May 2015 Notes and require the hedge counterparty to deliver shares to the Company in an amount equal to the shares required to be delivered by the Company to the note holder for the excess conversion value.

Warrants

At September 30, 2012, the outstanding warrants of up to 27.5 million shares of common stock underlying our May 2015 Notes, had a strike price of approximately $8.09 per share, subject to additional anti-dilution and certain other customary adjustments.

As of September 30, 2012, the remaining unamortized issuance costs of approximately $14,000 and the unamortized discount of approximately $10,000 are being amortized to interest expense over the term of our February 2015 Notes, with a remaining amortization period of approximately 2.4 years.

Income Tax Disclosure [Text Block]

13. Income Taxes

For the three and nine months ended September 30, 2012 and 2011, income tax expense was primarily derived by applying the federal statutory rate of 35% to operating income before income taxes.

In general, our income tax returns are subject to examination by tax authorities for tax years 1995 forward. In May 2012, PDL received a “no-change” letter from the Internal Revenue Service (IRS) upon completion of an examination of the Company’s 2008 Federal tax return. The California Franchise Tax Board (FTB) is currently examining the Company’s 2008 and 2009 tax returns. Although the timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year, we do not anticipate any material change to the amount of our unrecognized tax benefits over the next 12 months.

- 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.

15. Subsequent Events

Revenue Interest Purchase Agreement

In October 2012, PDL entered into a Revenue Interests Purchase Agreement (Royalty Agreement) with AxoGen, Inc. (AxoGen), pursuant to which PDL will receive specified royalties on AxoGen’s Net Revenues (as defined in the Royalty Agreement) generated by the sale, distribution or other use of AxoGen’s products. The Royalty Agreement has an eight year term, and provides PDL with high single digit royalties based on AxoGen’s Net Revenues, subject to agreed-upon minimum payments as provided by the Royalty Agreement beginning in the fourth quarter of 2014, and the right to require AxoGen to repurchase the revenue contract at the end of the fourth year. AxoGen has been granted certain rights to call the revenue contract in years five through eight. The total consideration PDL paid to AxoGen for the royalty rights was $20.8 million, including the termination of an interim funding of $1.8 million in August 2012. AxoGen was required to use a portion of the proceeds from the Royalty Agreement to pay the outstanding balance under its existing credit facility. AxoGen plans to use the remainder of the proceeds to support the business plan for its products. The royalty rights are secured by the cash and accounts receivable of AxoGen.

Credit Agreement

In November 2012, PDL loaned to Wellstat Diagnostics, LLC (Wellstat) pursuant to a Credit Agreement (Credit Agreement) $40 million to be used by Wellstat in connection with its development and commercialization of small point of care diagnostic systems that can perform a wide variety of tests targeting the clinical diagnostics market. Of the $40 million borrowed, Wellstat Diagnostics will use approximately $11.6 million to repay an existing credit facility between PDL and the holders of Wellstat’s equity interests.

Outstanding principal under the Credit Agreement bears interest at the rate of 5.0% per annum, payable quarterly in arrears, in cash or paid-in-kind notes that add to the principal balance. The Credit Agreement matures at its latest on December 31, 2021. Wellstat is required to repay the outstanding principal and a specific target internal rate of return amount to PDL at maturity or upon the occurrence of certain key events such as a sale of Wellstat Diagnostics or substantially all of its assets or if Wellstat Diagnostics misses a specified revenue target for fiscal year 2017. The loan will be considered repaid at any time the aggregate amount of all payments made by Wellstat to PDL, including interest and any royalty payments, equals specified target internal rates of return set forth in the Credit Agreement. The target internal rates of return depend on whether the date of repayment is on or after December 31, 2014, and is higher after December 31, 2014. Upon commercialization of Wellstat's diagnostic systems, PDL will receive a low double digit royalty on Wellstat Diagnostics' net revenues.

The Credit Agreement is secured by a pledge of substantially all of the assets of Wellstat and a pledge of all of Wellstat’s equity interests by the holders thereof.

Accounting Policies, by Policy (Policies)	9 Months Ended
Accounting Policies, by Policy (Policies)	Sep. 30, 2012
Basis of Accounting [Text Block]	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. The financial statements include all adjustments (consisting only of normal recurring adjustments) the management of PDL BioPharma, Inc. (the Company, PDL, we, us or our) believes are necessary for a fair presentation of the periods presented. These interim financial results are not necessarily indicative of results expected for the full fiscal year or for any subsequent interim period. The accompanying Condensed Consolidated Financial Statements and related financial information should be read in conjunction with the audited Consolidated Financial Statements and the related notes thereto for the year ended December 31, 2011, included in our Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission. The Condensed Consolidated Balance Sheet at December 31, 2011, has been derived from the audited Consolidated Financial Statements at that date.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The Consolidated Financial Statements include the accounts of PDL and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.
Finance, Loans and Leases Receivable, Policy [Policy Text Block]	Notes Receivable We account for our notes receivable at amortized cost, net of unamortized origination fees, if any. Related fees and costs are recorded net of amounts reimbursed. Interest is accreted or accrued to interest income using the interest method.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Hedging We enter into foreign currency hedges to manage exposures arising in the normal course of business and not for speculative purposes. We hedge certain Euro-denominated currency exposures related to our licensees’ product sales with Euro forward contracts and, in 2011, Euro forward and option contracts. In general, these contracts are intended to offset the underlying Euro market risk in our royalty revenues. These contracts extend through the fourth quarter of 2014. We designate foreign currency exchange contracts used to hedge royalty revenues based on underlying Euro-denominated sales as cash flow hedges. At the inception of the hedging relationship and on a quarterly basis, we assess hedge effectiveness. The fair value of the Euro forward contracts is estimated using pricing models with readily observable inputs from actively quoted markets and is disclosed on a gross basis. The aggregate unrealized gain or loss, net of tax, on the effective portion of the hedge is recorded in stockholders’ deficit as accumulated other comprehensive income (loss). Gains or losses on cash flow hedges are recognized as an adjustment to royalty revenue in the same period that the hedged transaction impacts earnings as royalty revenue. Any gain or loss on the ineffective portions is reported in other income in the period the ineffectiveness occurs. During the third quarter of 2012, we de-designated and terminated a portion of our cash flow hedges. The gain realized was reclassified from other comprehensive income (loss) to other income in the third quarter. See Note 5 for additional information on our foreign currency hedge transactions.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Income In the first quarter of 2012, we adopted Financial Accounting Standards Board (FASB) accounting standard update (ASU) 2011-05, and have presented the components of other comprehensive income (loss) in the Condensed Consolidated Statements of Comprehensive Income. Also in accordance with this ASU, we have applied this guidance retrospectively to all periods presented. The adoption of the guidance was a change to the presentation of other comprehensive income (loss) and had no effect on our condensed consolidated financial statements. See Note 14 for our discussion of accumulated other comprehensive income (loss).
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In December 2011, the FASB issued ASU 2011-11 requiring new disclosures associated with offsetting financial instruments and derivative instruments on the balance sheet that will enable users to evaluate the effect on an entity’s financial position. The ASU will be effective in the first quarter of 2013, but is not expected to have a material impact on our financial statements.

- Definition

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents 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. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months.
