NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2013

(Unaudited)

1. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. GAAP for interim financial information. The financial statements include all adjustments (consisting only of normal recurring adjustments) that management of PDL 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, 2012, included in our Annual Report on Form 10-K filed with the SEC. The Condensed Consolidated Balance Sheet at December 31, 2012, has been derived from the audited Consolidated Financial Statements at that date.

Principles of Consolidation

The Condensed Consolidated Financial Statements include the accounts of PDL and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. Our condensed consolidated financial statements are prepared in accordance with GAAP and the rules and regulations of the SEC.

Notes Receivable and Other Long-Term Receivables

We account for our notes receivable at amortized cost, net of unamortized origination fees, if any.  Related fees and costs are recorded net of any 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 as follows:

		Three Months Ended September 30,				Nine Months Ended September 30,
Licensee	Product Name	2013		2012		2013		2012
Genentech	Avastin®	33	%	30	%	34	%	31	%
	Herceptin®	32	%	36	%	33	%	35	%
	Lucentis®	14	%	15	%	17	%	18	%
Biogen Idec1	Tysabri®	12	%	14	%	11	%	12	%

______________________

¹ In April 2013, Biogen Idec completed its purchase of Elan's interest in Tysabri. Prior to this our licensee for Tysabri was identified as Elan.

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

9

At the inception of each hedging relationship and on a quarterly basis, we assess hedge effectiveness. The fair value of the Euro 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 component of the hedge is recorded in stockholders’ equity (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 portion of our hedge contracts is reported in interests and other income, net in the period the ineffectiveness occurs.

Comprehensive Income

In the first quarter of 2012, we adopted FASB 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

In January 2013, we adopted the provisions of ASU 2013-01, issued by the FASB, which requires new asset and liability offsetting disclosures for derivatives, repurchase agreements and security lending transactions to the extent that they are: (1) offset in the financial statements or (2) subject to an enforceable master netting arrangement or similar agreement. We do not have any repurchase agreements and do not participate in securities lending transactions. Our derivative instruments are not offset in the financial statements and are not subject to any right of offset provisions with our counterparties. Accordingly, this amendment did not have a material impact on our Condensed Consolidated Financial Statements. Additional information about derivative instruments can be found in Note 5.

In February 2013, FASB amended ASC 220, “Comprehensive Income.” This amendment requires companies to report, in one place, information about reclassifications (by component) out of accumulated other comprehensive income (loss). In addition, this amendment requires companies to present the related line item effect of significant reclassifications on the statement where income is presented. We adopted the provisions of this amendment during the first quarter of 2013, which affects only the display of information and does not change existing recognition and measurement requirements in our Condensed Consolidated Financial Statements.

Net income per basic share	$	0.40	$	0.35	$	1.45	$	1.16
Net income per diluted share	$	0.36	$	0.32	$	1.31	$	1.08

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 by the Company.

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 February 2015 Notes, our Series 2012 Notes and our May 2015 Notes on a weighted average basis for the period that the notes were outstanding, including the effect of adding back interest expense and the underlying shares using the if-converted method. In the first quarter of 2012, $179.0 million aggregate principal of our February 2015 Notes was exchanged for our Series 2012 Notes, and in the third quarter of 2013, $1.0 million aggregate principal of our February 2015 Notes was exchanged for our Series 2012 Notes, and the February 2015 Notes were retired.

In May 2011, we issued our May 2015 Notes, and in January and February 2012, we issued our Series 2012 Notes. 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, shown in the table above, include the shares issuable in respect of such excess.

We excluded from our calculations of net income per diluted share 20.8 million and 19.2 million shares for our warrants for the three months ended September 30, 2013 and 2012, respectively, and 20.8 million and 19.2 million shares for the nine months ended September 30, 2013 and 2012, respectively, for warrants issued in 2011, because the exercise price of the warrants exceeded the VWAP 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, issued in 2011, will always be anti-dilutive and therefore 24.4 million and 22.6 million shares were excluded from our calculations of net income per diluted share for the three months ended September 30, 2013 and 2012, respectively, and 24.4 million and 22.6 million shares were excluded for the nine months ended September 30, 2013 and 2012, respectively, because they have no effect on diluted net income per share. For information related to the conversion rates on our convertible debt, see Note 9.

11

For the three months ended September 30, 2013, we excluded approximately 121,000 and 10,000 shares underlying outstanding stock options and restricted stock awards, respectively, and for the nine months ended September 30, 2013, we excluded approximately 133,000 and zero shares underlying outstanding stock options and restricted stock awards, respectively, calculated on a weighted average basis, from our net income per diluted share calculations because their effect was anti-dilutive.

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

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 pay 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	$	—	$	7,508	$	7,508	$	—	$	7,581	$	7,581

The fair value of the certificates of deposit is determined using quoted market prices for similar instruments and non-binding market prices that are corroborated by observable market data. At December 31, 2012, the certificates of deposit included a $20.0 million certificate of deposit that was restricted as it was purchased to collateralize the line of credit for Merus Labs; see Note 6.

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

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

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

There have been no transfers between levels during the three and nine months ended September 30, 2013, and December 31, 2012. The Company recognizes transfers between levels on the date of the event or change in circumstances that caused the transfer.

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, 2013, the estimated fair value of our Avinger note receivable, as of September 30, 2013 and December 31, 2012, the estimated fair values of our Wellstat Diagnostics note receivable and AxoGen note receivable and derivative, and as of December 31, 2012, the estimated fair value of our Merus Labs note receivable, were determined using one or more discounted cash flow models, incorporating expected principal payments and the interest rate extended for notes with fixed interest rates and incorporating expected payments for notes with a variable rate of return.

On September 30, 2013, and December 31, 2012, the carrying value of the AxoGen note and derivative approximated its estimated fair value. We determined this note to be a Level 3 asset, as our valuation utilized significant unobservable inputs, including estimates of AxoGen's future revenues, expectations about settlement and required yield. To provide support for the estimated fair value measurement, we considered forward looking performance related to AxoGen and current measures associated with high yield indices, and reviewed the terms and yields of notes placed by specialty finance and venture firms both across industries and in a similar sector. Additionally, we reviewed market yield indices for changes since the issuance of the note. We observed no material events with AxoGen or in the market in which it participates since the placement. The carrying value and estimated fair value of the AxoGen note include the value of a change of control embedded derivative valued at $1.0 million and $0.6 million at September 30, 2013, and December 31, 2012, respectively. We utilized discounted cash flows and probability analysis to determine the fair value of the embedded derivative.

On September 30, 2013, and December 31, 2012, the carrying value of the note receivable from Wellstat Diagnostics approximates its fair value. We determined this note to be a Level 3 asset, as our valuation utilized significant unobservable inputs. Due to the breach of the credit agreement as of December 31, 2012, as discussed in Note 6, we considered the fair value of the underlying collateral when estimating fair value of the note. The note is collateralized by all assets and equity interest in Wellstat Diagnostics. The fair value of the collateral was determined by using a discounted cash flow analysis related to the underlying technology included in the collateral. The discounted cash flow was based upon expected income from sales of planned products over a 15-year period. The terminal value was estimated using selected market multiples based on sales and EBITDA. Our valuation of the collateral utilized significant unobservable inputs including a discount rate of 35%, terminal value EBITDA multiple of 17.5, terminal value sales multiple of 3.0 and future revenue and expenses related to commercialization of the borrower's technology.

13

On September 30, 2013, the carrying value of the Avinger note approximates its fair value. We determined this note to be a Level 3 asset, as our valuation utilized significant unobservable inputs, including a discount rate of 18.5%, estimates of Avinger's future revenues, expectations about settlement and required yield. To provide support for the fair value measurement, we considered forward looking performance related to Avinger, current measures associated with high yield and Standard & Poor's Leveraged Commentary & Data indices, and reviewed the terms and yields of notes placed by specialty finance and venture firms both across industries and in a similar sector.

The fair values of our convertible notes were determined using quoted market pricing or dealer quotes.

4. Cash Equivalents and Investments

As of September 30, 2013, and December 31, 2012, we had invested our excess cash balances primarily in money market funds, certificates of deposit, corporate securities and corporate debt securities. Our securities are classified as available-for-sale and are carried at estimated fair value, with unrealized gains and losses reported in accumulated other comprehensive income (loss) in stockholders’ equity (deficit), net of estimated taxes. 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.

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, 2013, and December 31, 2012, 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 flows under the de-designated contracts were probable to not occur, and recorded a gain of approximately $391,000 to interest and other income, net, 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.

The notional amounts, Euro exchange rates and fair values of our Euro forward contracts designated as cash flow hedges were as follows:

6. Notes Receivable and Other Long-term Receivables

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

Wellstat Diagnostics Note Receivable and Credit Agreement

In March 2012, the Company executed a $7.5 milliontwo-year senior secured note receivable with the holders of the equity interests in Wellstat Diagnostics. In addition to bearing interest at 10% per annum, the note gave PDL certain rights to negotiate for certain future financing transactions. In August 2012, PDL and the borrowers amended the note receivable, providing a senior secured note receivable of $10.0 million, bearing interest at 12% per annum, to replace the original $7.5 million note. This $10.0 million note was repaid on November 2, 2012.

On November 2, 2012, the Company and Wellstat Diagnostics entered into a $40.0 million credit agreement pursuant to which the Company is to accrue quarterly interest payments at the rate of 5% per annum (payable in cash or in kind). In addition, PDL will receive quarterly royalty payments based on a low double digit royalty rate of Wellstat Diagnostics' net revenues, generated by the sale, distribution or other use of Wellstat Diagnostics' products, if any, commencing upon the commercialization of its products.

In January 2013, the Company was informed that, as of November 2012, Wellstat Diagnostics had used funds contrary to the terms of the credit agreement and breached Sections 2.1.2 and 7 of the credit agreement. PDL sent Wellstat Diagnostics a notice of default on January 22, 2013, and accelerated the amounts owed under the credit agreement. In connection with the notice of default, PDL exercised one of its available remedies and transferred approximately $8.1 million of available cash from a bank account of Wellstat Diagnostics to PDL and applied the funds to amounts due under the credit agreement. On February 28, 2013, the parties entered into a forbearance agreement whereby PDL agreed to refrain from exercising additional remedies for 120 days while Wellstat Diagnostics raised funds to capitalize the business and the parties attempted to negotiate a revised credit agreement. PDL agreed to provide up to $7.9 million to Wellstat Diagnostics to fund the business for the 120-day forbearance period under the terms of the forbearance agreement. Following the conclusion of the June 28 forbearance period, the Company agreed to forbear in its exercise of remedies for additional periods of time to allow the owners and affiliates of Wellstat Diagnostics to complete a pending financing transaction. During such forbearance period, the Company provided approximately $1.3 million to Wellstat Diagnostics to fund ongoing operations of the business. During the nine months endedSeptember 30, 2013, approximately $8.7 million was advanced pursuant to the forbearance agreement.

16

On August 15, 2013, the owners and affiliates of Wellstat Diagnostics completed a financing transaction to fulfill its obligations under the forbearance agreement. On August 15, 2013, the Company entered into an amended and restated credit agreement with Wellstat Diagnostics. The Company determined that the new agreement should be accounted for as a modification of the existing agreement.

Except as otherwise described here, the material terms of the amended credit agreement are substantially the same as those of the original credit agreement, including quarterly interest payments at the rate of 5% per annum (payable in cash or in kind). In addition, PDL will continue to receive quarterly royalty payments based on a low double digit royalty rate of Wellstat Diagnostics' net revenues. However, pursuant to the amended credit agreement: (i) the principal amount was reset to approximately $44.1 million which was comprised of approximately $33.7 million original loan principal and interest, $1.3 million term loan principal and interest and $9.1 million forbearance principal and interest; (ii) the specified internal rates of return increased; (iii) the default interest rate was increased; (iv) Wellstat Diagnostics' obligation to provide certain financial information increased in frequency to monthly; (v) internal financial controls were strengthened by requiring Wellstat Diagnostics to maintain an independent, third-party financial professional with control over fund disbursements; (vi) the Company waived the existing events of default; and (vii) the owners and affiliates of Wellstat Diagnostics are required to contribute additional capital to Wellstat Diagnostics upon the sale of an affiliate entity. The restated credit agreement continues to have an ultimate maturity date of December 31, 2021 (but may mature earlier upon certain specified events).

When the principal amount was reset it resulted in a $2.5 million reduction of the carrying value and was recorded as a financing cost as a component of interest and other income, net. The new carrying value is lower as a function of the variable nature of the internal rate of return to be realized by the Company based on when the note is repaid. The internal rate of return calculation, although increased, was reset when the credit agreement was amended and restated.

Wellstat Diagnostics may prepay the amended credit agreement at a price that, together with interest and royalty payments already made to the Company, would generate a specified internal rate of return to the Company. In the event of a change of control, bankruptcy or certain other customary events of defaults, or Wellstat Diagnostics' failure to achieve a specified annual revenue threshold in 2017, Wellstat Diagnostics will be required to prepay the credit agreement at a price that, together with interest and royalty payments already made to the Company, would generate a specified internal rate of return to the Company. The amended credit agreement is secured by a pledge of all of the assets of Wellstat Diagnostics, a pledge of all of Wellstat Diagnostics’ equity interests by the holders thereof, and a second lien on the assets of the affiliates of Wellstat Diagnostics.The Company believes the fair value of the collateral is not less than$76.6 million.

At September 30, 2013, and December 31, 2012, the carrying value of the note was included in non-current assets.

As of September 30, 2013, the Company determined that its interest in Wellstat Diagnostics represented a variable interest in a Variable Interest Entity since Wellstat Diagnostics' equity was not sufficient to finance its operations without amounts advanced to it under the Company's note and forbearance agreement. However, the Company does not have the power to unilaterally direct operational activities of Wellstat Diagnostics and is not the primary beneficiary of Wellstat Diagnostics; therefore, Wellstat Diagnostics is not subject to consolidation.

As of September 30, 2013, the carrying value of all amounts advanced to Wellstat Diagnostics was $45.3 million, which was recorded in notes receivable. As of September 30, 2013, the maximum loss exposure was $45.3 million.

Merus Labs Note Receivable and Credit Agreement

In July 2012, PDL loaned $35.0 million to Merus Labs in connection with its acquisition of a commercial-stage pharmaceutical product and related assets. In addition, PDL agreed to provide a $20.0 million letter of credit on behalf of Merus Labs for the seller of the assets to draw upon to satisfy the remaining $20.0 million purchase price obligation. The seller made this draw on the letter of credit in July 2013 and an additional loan to Merus Labs for $20.0 million was recorded for an aggregate of $55.0 million in total borrowings.

Outstanding borrowings under the July 2012 loan bore interest at the rate of 13.5% per annum and outstanding borrowings as a result of the draw on the letter of credit bore interest at the rate of 14.0% per annum. Merus Labs was required to make four periodic principal payments in respect of the July 2012 loan, with repayment of the remaining principal balance of all loans due on March 31, 2015. The borrowings were subject to mandatory prepayments upon certain asset dispositions or debt issuances as set forth in the credit agreement. Merus Labs made the first of these payments in December 2012 in the amount of $5.0 million, and made the second payment in June 2013 in the amount of $7.5 million. In September 2013, Merus Labs made two additional payments totaling $43.3 million, including the prepayment fee, in order to pay its remaining outstanding balance.

17

In September 2013, Merus Labs prepaid in full its obligations under the credit agreement , including accrued interest through the payment date and a prepayment fee of 1% of the aggregate principal amount outstanding at the time of repayment. There was no outstanding balance owed as of September 30, 2013.

AxoGen Note Receivable and Royalty Agreement

In October 2012, PDL entered into the Royalty Agreement with AxoGen pursuant to which the Company 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 years term and provides PDL with royalties of 9.95% based on AxoGen Net Revenues, subject to agreed-upon guaranteed quarterly minimum payments of approximately $1.3 to $2.3 million beginning in the fourth quarter of 2014, and the right to require AxoGen to repurchase the Royalty Agreement at the end of the fourth year. AxoGen has been granted certain rights to call the 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.

Under the Royalty Agreement, beginning on October 1, 2016, or in the event of the occurrence of a material adverse event or AxoGen's bankruptcy or material breach of the Royalty Agreement, the Company may require AxoGen to repurchase the royalty rights at a price that, together with payments already made by AxoGen, would generate a specified internal rate of return to the Company. The Company has concluded that the repurchase option is an embedded derivative which should be bifurcated and separately accounted for at fair value.

In the event of a change of control, AxoGen must repurchase the assigned interests from the Company for a repurchase price equal to an amount that, together with payments already made by AxoGen, would generate a 32.5% internal rate of return to the Company. The Company has concluded that the change of control provision is an embedded derivative that should be bifurcated and separately recorded at its estimated fair value. The estimated fair value of the change of control provision was approximately $1.0 million and $0.6 million as of September 30, 2013, and December 31, 2012, respectively. The estimated fair value of this embedded derivative is included in the carrying value of the AxoGen Note Receivable. The Company recognized approximately $0.0 million and $0.4 million related to the change in the estimated fair value of embedded derivative during the three and nine month periods ended September 30, 2013, respectively.

At any time after September 30, 2016, AxoGen, at its option, can repurchase the assigned interests under the Royalty Agreement for a price applicable in a change of control.

During the term of the Royalty Agreement, the Company is entitled to designate an individual to be a member of AxoGen's board of directors. The Company has exercised this right and on October 5, 2012, upon close of the transaction, the Company's President and Chief Executive Officer was elected to AxoGen's board of directors.

On August 14, 2013, PDL purchased 1,166,666 shares of AXGN at $3.00 per share, totaling $3.5 million. The shares are classified as available for sale and recorded as short term investments on the balance sheet. As of September 30, 2013, the shares were valued at $5.2 million, which results in an unrealized gain of $1.7 million and is recorded in other comprehensive income.

Avinger Note Receivable and Royalty Agreement

On April 18, 2013, PDL entered into a credit agreement with Avinger, under which we made available to Avinger up to $40.0 million to be used by Avinger in connection with the commercialization of its currently marketed lumivascular catheter devices and in the development of Avinger's lumivascular atherectomy device. Of the $40.0 million available to Avinger, we funded an initial $20.0 million, net of fees, at close of the transaction. Upon the attainment by Avinger of a certain revenue milestone to be accomplished no later than the end of the first half of 2014, we will fund them an additional amount between $10.0 million and $20.0 million (net of fees) at Avinger's election. Outstanding borrowings under the initial loan bear interest at a stated rate of 12% per annum, and any future outstanding borrowings as a result of an additional amount funded upon reaching the revenue milestone will bear interest at the rate of 14% per annum.

Avinger is required to make quarterly interest and principal payments. Principal repayment will commence on: (i) the eleventh interest payment date if the revenue milestone is not achieved or (ii) the thirteenth interest payment date if the revenue milestone is achieved. The principal amount outstanding at commencement of repayment, after taking into account any payment-in-kind, will be repaid in equal installments until final maturity of the loans. The loans will mature in April 2018.

18

In connection with entering into the credit agreement, the Company will receive a low, single-digit royalty on Avinger's net revenues through April 2018. Avinger may prepay the outstanding principal and accrued interest on the notes receivable at any time. If Avinger repays the notes receivable prior to April 2018, the royalty on Avinger's net revenues will be reduced by 50% and will be subject to certain minimum payments from the prepayment date through April 2018.

The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Avinger and any of its subsidiaries (other than controlled foreign corporations, if any). The credit agreement provides for a number of standard events of default, including payment, bankruptcy, covenant, representation and warranty and judgment defaults.

Legal Proceedings

Genentech / Roche Matter

Communications with Genentech regarding European SPCs

In August 2010, we received a letter from Genentech, sent on behalf of Roche and Novartis, asserting that Avastin, Herceptin, Lucentis and Xolair do not infringe the SPCs granted to PDL by various countries in Europe for covering those 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 Avastin, Herceptin, Lucentis and Xolair. The SPCs covering Avastin, Herceptin, Lucentis and Xolair effectively extend our European patent protection for the '216B Patent generally until December 2014, except that the SPCs for Herceptin will generally expire in July 2014.

Genentech’s letter does not suggest that any of the Genentech Products do not infringe PDL’s U.S. patents to the extent that such Genentech Products are U.S.-based Sales. Genentech’s quarterly royalty payments received after receipt of the letter have 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 Avastin, Herceptin, Lucentis and Xolair that are both manufactured and sold outside of the United States. Royalties on sales of Avastin, Herceptin, Lucentis and Xolair that are ex-U.S.-based Manufacturing and Sales accounted for approximately 42% of our royalty revenues for the nine months endedSeptember 30, 2013.

We believe that the SPCs are enforceable, 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 and Arbitration with Genentech

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 Avastin, Herceptin, Lucentis and Xolair.

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.

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 parties have been engaged in discovery motion practice. On March 29, 2013, the court affirmed an order of the discovery commissioner requiring the production of certain documents in the possession of Roche and Genentech to PDL. Roche and Genentech have communicated to us that they have requested review of the court's order from the Nevada Supreme Court. The parties have agreed to a stay in the proceedings pending the decision of the Nevada Supreme Court regarding whether they will review the court's order. In the event that the Nevada Supreme Court agrees to consider Roche and Genentech's request and review the court's order, we expect a lengthy delay in the case schedule for a period that may extend for a number of months, and, while no trial date is currently scheduled with the District Court, the likelihood is that a trial date will be at some point between mid-2014 to mid-2015. The outcome of this litigation is uncertain and we may not be successful in our allegations.

On June 7, 2013, the Company filed a Notice of Arbitration against Genentech with the American Arbitration Association in Voorhees, New Jersey, alleging, inter alia, that Genentech underpaid royalties going back to at least 2007 and impeded PDL's attempts to have Genentech's books and records inspected to determine whether Genentech's past payments to PDL were accurately calculated.

In 2009, PDL retained KPMG to conduct an independent inspection and analysis of the books and records of Genentech and its sublicensees for the three year period covering January 1, 2007 to December 31, 2009, a right granted to PDL under PDL's Patent License Master Agreement and license agreements with Genentech. KPMG reported to PDL that, due to limitations on its inspection imposed by Genentech, it was unable to assess the completeness or accuracy of Genentech's reporting of royalties. KPMG concluded that, based on the limited information it was able to review, Genentech appears to have underpaid PDL in an amount that, if substantiated, PDL believes would be material. Genentech has informed PDL that it disagrees with KPMG's conclusions and that it believes that it has correctly calculated royalties due.

In the arbitration, PDL: (i) requests a declaration of the parties' rights and obligations with respect to reporting and payment of royalties under the license agreements; (ii) alleges that Genentech has breached the license agreements due to its obstruction of KPMG's inspection and underpayment of royalties; and (iii) alleges that Genentech breached the implied covenant of good faith and fair dealing by depriving PDL of the benefits of the license agreements through its obstruction of the inspection, which we further assert concealed the nature and extent of its underpayment.

On July 3, 2013, Genentech filed its Response and Counterclaim in which Genentech requests that the arbitrator (i) reject PDL's claims that Genentech breached the license agreements by underpaying royalties owed to PDL, obstructing KPMG's inspection, or violating the covenant of good faith and fair dealing; (ii) reject PDL's claim that Genentech owed any royalties to PDL on Herceptin, Avastin and Xolair manufactured and sold outside of the United States prior to December 27, 2009 on the ground that those products did not infringe the '216B patent prior to its expiration; (iii) offset any royalties underpaid during the audit period by the amount Genentech claims to have overpaid in royalties attributable to the sale of Herceptin, Avastin and Xolair manufactured and sold outside of the United States prior to December 27, 2009; and (iv) award damages to Genentech in the amount of $428,751, representing royalties Genentech overpaid during the audit period, as well as costs and reasonable attorney's fees. Genentech's counterclaim does not challenge whether Herceptin, Avastin and Xolair manufactured and sold outside of the United States after December 27, 2009, are Licensed Products (and subject to a royalty under PDL's SPCs issued to such products in Europe) as Genentech's ability to contest infringement of PDL's SPCs is the subject of pending litigation in Nevada.

20

The parties have mutually agreed to stay the arbitration proceedings and to extend the deadline for responses in the Nevada litigation to allow time for discussions to occur to determine if a settlement of certain issues is possible. The parties may not reach agreement regarding settlement terms and PDL expects that it will renew its litigation efforts if settlement is unsuccessful.

The outcome of this arbitration is uncertain, and PDL may not be successful in its allegations.

Other Legal Proceedings

In addition, from time to time, we are subject to various other legal proceedings and claims that arise in the ordinary course of business and that we do not expect to materially impact our financial statements.

Lease Guarantee

In connection with the Spin-Off, we entered into amendments to the leases for our former facilities in Redwood City, California, under which Facet was added as a co-tenant, 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 could 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, 2013, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately $92.7 million. If Facet were to default, we could 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.

We have recorded a liability of $10.7 million on our Condensed Consolidated Balance Sheets as of September 30, 2013, and December 31, 2012, related to this guarantee. In future periods, we may adjust this liability for any changes in the ultimate outcome of this matter that are both probable and estimable.

As of September 30, 2013, PDL was in compliance with all applicable debt covenants, and embedded features of all debt agreements were evaluated and did not need to be accounted for separately.

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. In August 2013, the Company entered into a separate privately negotiated exchange agreement under which it retired the final $1.0 million aggregate principal amount of the Company's outstanding February 2015 Notes. Pursuant to the exchange agreement, the holder of the February 2015 Notes received $1.0 million aggregate principal amount of the

21

Company's Series 2012 Notes. Immediately following the exchange, no principal amount of the February 2015 Notes remained outstanding and $180.0 million principal amount of the Series 2012 Notes is outstanding.

The terms of the Series 2012 Notes are governed by the indenture dated as of January 5, 2012, 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.

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 as follows:

As of September 30, 2013, our Series 2012 Notes are convertible into 179.777 shares of the Company’s common stock per $1,000 of principal amount, or approximately $5.56 per common share, subject to further adjustment upon certain events including dividend payments. As of September 30, 2013, the remaining discount amortization period was 1.4 years.

Our common stock exceeded the conversion threshold price of $7.37 for at least 20 days during the 30 consecutive trading days ended June 30, 2013; accordingly, the Series 2012 Notes were convertible at the option of the holder during the quarter ended September 30, 2013. Our common stock price exceeded the conversion threshold price of $7.23 per common share for at least 20 days during the 30 consecutive trading days ended September 30, 2013; accordingly, the Series 2012 Notes are convertible at the option of the holder during the quarter ending December 31, 2013. The Series 2012 Notes have been classified as current as the notes will be due upon demand within one year of the quarter ended September 30, 2013. At September 30, 2013, the if-converted value of our Series 2012 Notes exceeded their principal amount by approximately $77.9 million.

May 2015 Notes

On May 16, 2011, we issued $155.3 million in aggregate principal amount, at par, of our May 2015 Notes in an underwritten public offering, for net proceeds of $149.7 million. Our May 2015 Notes are due May 1, 2015, and we pay interest at 3.75% on our May 2015 Notes semiannually in arrears on May 1 and November 1 of each year, beginning November 1, 2011. Proceeds from our May 2015 Notes, net of amounts used for purchased call option transactions and provided by the warrant transactions described below, were used to redeem our 2012 Notes. Upon the occurrence of a fundamental change, as defined in the indenture, holders have the option to require PDL to repurchase their May 2015 Notes at a purchase price equal to 100% of the principal, plus accrued interest.

Our May 2015 Notes are convertible under any of the following circumstances:

• During any fiscal quarter ending after the quarter ending June 30, 2011, if the last reported sale price of our 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 notes on the last day of such preceding fiscal quarter;

• During the five business-day period immediately after any five consecutive trading-day period, which we refer to as the measurement period, in which the trading price per $1,000 principal amount of notes for each trading day of that measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the notes for each such day;

• Upon the occurrence of specified corporate events as described further in the indenture; or

• At any time on or after November 1, 2014.

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 our May 2015 Notes between the fair value of the debt component and the fair value of the common stock conversion feature. Using an assumed borrowing rate of 7.5%, which represents the estimated market interest rate for a similar nonconvertible instrument available to us on the date of issuance, we recorded a total debt discount of $18.9 million, allocated $12.3 million to additional paid-in capital and allocated $6.6 million to deferred tax liability. The discount is being amortized to interest expense over the term of our May 2015 Notes and increases interest expense during the term of our May 2015 Notes from the 3.75% cash coupon interest rate to an effective interest rate of 7.5%. As of September 30, 2013, the remaining discount amortization period is 1.6 years.

As of September 30, 2013, our May 2015 Notes are convertible into 157.37 shares of the Company’s common stock per $1,000 of principal amount, or approximately $6.35 per common share, subject to further adjustment upon certain events including dividend payments.

Our common stock did not exceed the conversion threshold price of $8.42 for at least 20 days during the 30 consecutive trading days ended June 30, 2013; accordingly, the May 2015 Notes were not convertible at the option of the holder during the quarter ended September 30, 2013. Our common stock price did not exceed the conversion threshold price of $8.26 per common share for at least 20 days during the 30 consecutive trading days ended September 30, 2013; accordingly, the May 2015 Notes are not convertible at the option of the holder during the quarter ending December 31, 2013. At September 30, 2013, the if-converted value of our May 2015 exceeded their principal amount by approximately $39.5 million.

Purchased Call Options and Warrants

In connection with the issuance of our May 2015 Notes, we entered into purchased call option transactions with two hedge counterparties. We paid an aggregate amount of $20.8 million, plus legal fees, for the purchased call options with terms substantially similar to the embedded conversion options in our May 2015 Notes. The purchased call options cover, subject to anti-dilution and certain other customary adjustments substantially similar to those in our May 2015 Notes, approximately 24.0 million shares of our common stock. 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. The purchased call options expire on May 1, 2015, or the last day any of our May 2015 Notes remain outstanding.

In addition, we sold to the hedge counterparties warrants exercisable, on a cashless basis, for the sale of rights to receive up to 27.5 million shares of common stock underlying our May 2015 Notes. We received an aggregate amount of $10.9 million for the sale from the two counterparties. The warrant counterparties may exercise the warrants on their specified expiration dates that occur over a period of time ending on January 20, 2016. If the VWAP of our common stock, as defined in the warrants, exceeds the strike price of the warrants, we will deliver to the warrant counterparties shares equal to the spread between the VWAP on the date of exercise or expiration and the strike price. If the VWAP is less than the strike price, neither party is obligated to deliver anything to the other.

The purchased call option transactions and warrant sales effectively serve to reduce the potential dilution associated with conversion of our May 2015 Notes. The strike prices are approximately $6.35 and $7.48, subject to further adjustment upon certain events including dividend payments, for the purchased call options and warrants, respectively.

If the share price is above $6.35, but below $7.48, upon conversion of our May 2015 Notes, the purchased call options will offset the share dilution, because the Company will receive shares on exercise of the purchased call options equal to the shares

24

that the Company must deliver to the note holders. If the share price is above $7.48, upon exercise of the warrants, the Company will deliver shares to the counterparties in an amount equal to the excess of the share price over $7.48. For example, a 10% increase in the share price above $7.48 would result in the issuance of 1.9 million incremental shares upon exercise of the warrants. As our share price continues to increase, additional dilution would occur.

While the purchased call options are expected to reduce the potential equity dilution upon conversion of our May 2015 Notes, prior to conversion or exercise, our May 2015 Notes and the warrants could have a dilutive effect on the Company’s earnings per share to the extent that the price of the Company’s common stock during a given measurement period exceeds the respective exercise prices of those instruments. As of September 30, 2013, and December 31, 2012, the market price condition for convertibility of our May 2015 Notes was not met and there were no related purchased call options or warrants exercised.

The purchased call options and warrants are considered indexed to PDL stock, require net-share settlement, and met all criteria for equity classification at inception and at September 30, 2013, and December 31, 2012. The purchased call options cost, including legal fees, of $20.8 million, less deferred taxes of $7.2 million, and the $10.9 million received for the warrants, was recorded as adjustments to additional paid-in capital. Subsequent changes in fair value will not be recognized as long as the purchased call options and warrants continue to meet the criteria for equity classification.

February 2015 Notes

On November 1, 2010, we completed an exchange of $92.0 million in aggregate principal of our 2012 Notes in separate, privately negotiated transactions with the note holders. In the exchange transactions, the note holders received $92.0 million in aggregate principal of our February 2015 Notes, and we recorded a net gain of $1.1 million. As part of the transaction, we placed an additional $88.0 million in aggregate principal of our February 2015 Notes. In January 2012, we completed an exchange transaction where we exchanged and subsequently retired approximately $169.0 million aggregate principal amount of our February 2015 Notes for approximately $169.0 million aggregate principal amount of new Series 2012 Notes, plus a cash payment of $5.00 for each $1,000 principal amount tendered for a total cash incentive payment of approximately $0.8 million. In February 2012, we entered into separate privately negotiated exchange agreements under which we retired an additional $10.0 million aggregate principal amount of our February 2015 Notes for $10.0 million aggregate principal amount of our Series 2012 Notes. In August 2013, the Company entered into a separate privately negotiated exchange agreement under which it retired the final $1.0 million aggregate principal amount of the Company's outstanding February 2015 Notes. Pursuant to the exchange agreement, the holder of the February 2015 Notes received $1.0 million aggregate principal amount of the Company's Series 2012 Notes. Immediately following the exchange, no principal amount of the February 2015 Notes remained outstanding. Our February 2015 Notes bore interest at 2.875% per annum.

12. Cash Dividends

On January 23, 2013, our board of directors declared that the regular quarterly dividends to be paid to our stockholders in 2013 will be $0.15 per share of common stock, payable on March 12, June 12, September 12 and December 12 of 2013 to stockholders of record on March 5, June 5, September 5 and December 5 of 2013, the record dates for each of the dividend payments, respectively.

In connection with the September 12, 2013, dividend payment, the conversion rates for our convertible notes adjusted as follows:

Convertible Notes	Conversion Rate per $1,000 Principal Amount	Approximate Conversion Price Per Common Share		Effective Date
Series 2012 Notes	179.777	$	5.56	September 3, 2013
May 2015 Notes	157.3700	$	6.35	September 3, 2013

13. Income Taxes

For the three and nine months ended September 30, 2013 and 2012, income tax expense was primarily derived by applying the federal statutory rate of 35% to operating income before income taxes.

During the second and third quarters of 2013, the Company released tax liabilities for the federal tax credits taken on the 2009 income tax return, in the amount of $5.7 million and $0.4 million, respectively. This resulted in a reduction to income tax expense for the second and third quarters of 2013. We expect to release additional tax liabilities in the third quarter of 2014 of approximately $7.0 million.

In general, our income tax returns are subject to examination by tax authorities for tax years 1996 forward. The California Franchise Tax Board is currently examining the Company’s 2008, 2009 and 2010 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, except as described above.

14. Accumulated Other Comprehensive Income (Loss)

Comprehensive income is comprised of net income and other comprehensive income (loss). We include unrealized net gains on investments held in our available-for-sale securities and unrealized gains (losses) on our cash flow hedges in other comprehensive income (loss), and present the amounts net of tax. Our other comprehensive income (loss) is included in our Condensed Consolidated Statements of Comprehensive Income.

26

The balance of accumulated other comprehensive income (loss), net of tax, was as follows:

15. Subsequent Events

LENSAR Credit Agreement

On October 1, 2013, PDL entered into a credit agreement with LENSAR, under which PDL made available to LENSAR up to $60 million to be used by LENSAR in connection with the commercialization of its currently marketed LENSAR Laser System. Of the $60 million available to LENSAR, an initial $40 million, net of fees, was funded by PDL at close of the transaction. Upon the attainment by LENSAR of a specified sales milestone to be accomplished no later than September 30, 2014, PDL will fund LENSAR an additional $20 million. Outstanding borrowings under the loans bear interest at the rate of 15.5% per annum, payable quarterly in arrears.

Principal repayment will commence on the thirteenth interest payment date or December 30, 2016. The principal amount outstanding at the commencement of repayment will be repaid in equal installments until final maturity of the loans. The loans will mature on October 1, 2018. LENSAR may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans. The loans are secured by all of the assets of LENSAR.

Depomed Royalty Purchase and Sales Agreement

On October 18, 2013, PDL entered into a royalty purchase and sale agreement with Depomed, Inc. and Depo DR Sub, LLC, a wholly owned subsidiary of Depomed, whereby the Company acquired the rights to receive royalties and milestones payables on sales of Type 2 diabetes products licensed by Depomed in exchange for a $240.5 million cash payment. The transaction closed simultaneously with the execution of the royalty agreement.

Under the terms of the royalty agreement, the Company will receive all royalty and milestone payments due under license agreements between Depomed and its licensees until the Company has received payments equal to two times the cash payment made to Depomed, after which all net payments received will be shared evenly between the Company and Depomed.

OVERVIEW

PDL BioPharma manages a portfolio of patents and royalty assets, consisting primarily of its Queen et al. antibody humanization patents and license agreements with various biotechnology and pharmaceutical companies. PDL pioneered the humanization of monoclonal antibodies and, by doing so, enabled the discovery of a new generation of targeted treatments for cancer and immunologic diseases for which it receives significant royalty revenue. PDL is currently focused on intellectual property asset management, investing in new income generating assets and maximizing value for its shareholders.

The company was formerly known as Protein Design Labs, Inc. and changed its name to PDL BioPharma, Inc. in 2006. PDL was founded in 1986 and is headquartered in Incline Village, Nevada.

In 2011, PDL initiated a strategy to bring in new income generating assets from the healthcare sector. To accomplish this goal, PDL seeks to provide non-dilutive growth capital and financing solutions to late stage public and private healthcare companies and offers immediate financial monetization of royalty streams to companies, academic institutions and inventors. PDL successfully executed on this strategy by deploying over $125 million in 2012 and continues to pursue this strategic initiative. PDL is focused on the quality of the income generating assets and potential returns on investment.

We continuously evaluate alternatives to increase return for our stockholders, for example, purchasing income generating assets, buying back or redeeming our convertible notes, repurchasing our common stock, paying dividends or selling the Company. At the beginning of each fiscal year, our board of directors reviews the Company's total annual dividend payment for the prior year and determines whether to increase, maintain or decrease the quarterly dividend payments for that year. The board of directors evaluates the financial condition of the Company and considers the economic outlook, corporate cash flow, the Company's liquidity needs and the health and stability of credit markets when determining whether to maintain or change the dividend.

Recent Developments

Dividend Payment and Effect on Conversion Rates for the Convertible Notes

On January 23, 2013, our board of directors declared that the regular quarterly dividends to be paid to our stockholders in 2013 will be $0.15 per share of common stock, payable on March 12, June 12, September 12 and December 12 of 2013 to stockholders of record on March 5, June 5, September 5 and December 5 of 2013, the record dates for each of the dividend payments, respectively. On September 12, 2013, we paid the regular quarterly dividend to our stockholders totaling $21.0 million using earnings generated in the three months ended September 30, 2013.

29

In connection with the September 12, 2013, dividend payment, the conversion rates for our convertible notes adjusted as follows:

Convertible Notes	Conversion Rate per $1,000 Principal Amount	Approximate Conversion Price Per Common Share		Effective Date
Series 2012 Notes	179.777	$	5.56	September 3, 2013
May 2015 Notes	157.3700	$	6.35	September 3, 2013

The adjustments were based on the amount of the dividend and the trading price of our stock under the terms of the applicable indenture.

Wellstat Diagnostics Forbearance Agreement

In January 2013, the Company was informed that, as of November 2012, Wellstat Diagnostics had used funds contrary to the terms of the credit agreement and breached Sections 2.1.2 and 7 of the credit agreement. PDL sent Wellstat Diagnostics a notice of default on January 22, 2013, and accelerated the amounts owed under the credit agreement. In connection with the notice of default, PDL exercised one of its available remedies and transferred approximately $8.1 million of available cash from a bank account of Wellstat Diagnostics to PDL and applied the funds to amounts due under the credit agreement. On February 28, 2013, the parties entered into a forbearance agreement whereby PDL agreed to refrain from exercising additional remedies for 120 days while Wellstat Diagnostics raised funds to capitalize the business and the parties attempted to negotiate a revised credit agreement. PDL agreed to provide up to $7.9 million to Wellstat Diagnostics to fund the business for the 120-day forbearance period under the terms of the forbearance agreement. Following the conclusion of the June 28 forbearance period, the Company agreed to forbear in its exercise of remedies for additional periods of time to allow the owners and affiliates of Wellstat Diagnostics to complete a pending financing transaction. During such forbearance period, the Company provided approximately $1.3 million to Wellstat Diagnostics to fund ongoing operations of the business. During the nine months endedSeptember 30, 2013, approximately $8.7 million was advanced pursuant to the forbearance agreement.

On August 15, 2013, the owners and affiliates of Wellstat Diagnostics completed a financing transaction to fulfill its obligations under the forbearance agreement. On August 15, 2013, the Company entered into an amended and restated credit agreement with Wellstat Diagnostics. The Company determined that the new agreement should be accounted for as a modification of the existing agreement.

Except as otherwise described here, the material terms of the amended credit agreement are substantially the same as those of the original credit agreement, including quarterly interest payments at the rate of 5% per annum (payable in cash or in kind). In addition, PDL will continue to receive quarterly royalty payments based on a low double digit royalty rate of Wellstat Diagnostics' net revenues. However, pursuant to the amended credit agreement: (i) the principal amount was reset to approximately $44.1 million which was comprised of approximately $33.7 million original loan principal and interest, $1.3 million term loan principal and interest and $9.1 million forbearance principal and interest; (ii) the specified internal rates of return increased; (iii) the default interest rate was increased; (iv) Wellstat Diagnostics' obligation to provide certain financial information increased in frequency to monthly; (v) internal financial controls were strengthened by requiring Wellstat Diagnostics to maintain an independent, third-party financial professional with control over fund disbursements; (vi) the Company waived the existing events of default; and (vii) the owners and affiliates of Wellstat Diagnostics are required to contribute additional capital to Wellstat Diagnostics upon the sale of an affiliate entity. The restated credit agreement continues to have an ultimate maturity date of December 31, 2021 (but may mature earlier upon certain specified events).

Wellstat Diagnostics may prepay the amended credit agreement at a price that, together with interest and royalty payments already made to the Company, would generate a specified internal rate of return to the Company. In the event of a change of control, bankruptcy or certain other customary events of defaults, or Wellstat Diagnostics' failure to achieve a specified annual revenue threshold in 2017, Wellstat Diagnostics will be required to prepay the credit agreement at a price that, together with interest and royalty payments already made to the Company, would generate a specified internal rate of return to the Company. The amended credit agreement is secured by a pledge of all of the assets of Wellstat Diagnostics, a pledge of all of Wellstat Diagnostics’ equity interests by the holders thereof, and a second lien on the assets of the affiliates of Wellstat Diagnostics.The Company believes the fair value of the collateral is not less than$76.6 million.

As of September 30, 2013, the Company determined that its interest in Wellstat Diagnostics represented a variable interest in a Variable Interest Entity since Wellstat Diagnostics' equity was not sufficient to finance its operations without amounts advanced

30

to it under the Company's note and forbearance agreement. However, the Company does not have the power to unilaterally direct operational activities of Wellstat Diagnostics and is not the primary beneficiary of Wellstat Diagnostics; therefore, Wellstat Diagnostics is not subject to consolidation.

As of September 30, 2013, the carrying value of all amounts advanced to Wellstat Diagnostics was $45.3 million, which was recorded in notes receivable.

Subsequent Events

LENSAR, Inc. Credit Agreement

On October 1, 2013, PDL entered into a credit agreement with LENSAR, under which PDL made available to LENSAR up to $60 million to be used by LENSAR in connection with the commercialization of its currently marketed LENSAR Laser System. Of the $60 million available to LENSAR, an initial $40 million, net of fees, was funded by PDL at close of the transaction. Upon the attainment by LENSAR of a specified sales milestone to be accomplished no later than September 30, 2014, PDL will fund LENSAR an additional $20 million. Outstanding borrowings under the loans bear interest at the rate of 15.5% per annum, payable quarterly in arrears.

Principal repayment will commence on the thirteenth interest payment date or December 30, 2016. The principal amount outstanding at the commencement of repayment will be repaid in equal installments until final maturity of the loans. The loans will mature on October 1, 2018. LENSAR may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans. The loans are secured by all of the assets of LENSAR.

The interest rates per annum applicable to amounts outstanding under the term loan are, at the Company’s option, either (a) the base rate plus 1.00%, or (b) the Eurodollar rate plus 2.00% per annum. Interest and principal payments under the credit agreement are due on the interest payment dates of January 31, April 30, and July 31 of 2014, with the remaining outstanding balance due on October 28, 2014.

Any future material domestic subsidiaries of the Company are required to guarantee the obligations of the Company under the credit agreement, except as otherwise provided by the credit agreement. The Company’s obligations under the Credit Agreement are secured by a lien on a substantial portion of its assets.

The credit agreement contains affirmative and negative covenants that the Company believes are usual and customary for a senior secured credit agreement. The credit agreement also requires compliance with certain financial covenants, including a maximum total leverage ratio and a debt service coverage ratio, in each case calculated as set forth in the credit agreement and compliance with which may be necessary to take certain corporate actions.

The credit agreement contains events of default that the Company believes are usual and customary for a senior

secured credit agreement.

31

Durata Credit Agreement

On October 31, 2013, PDL entered into a credit agreement with Durata, whereby the Company made available to Durata up to $70.0 million. Of the $70.0 million available to Durata, an initial $25.0 million (tranche one), net of fees, was funded by the Company at the close of the transaction.Upon marketing approval of dalbavancin in the United States, to be accomplished no later than December 31, 2014 (the tranche two milestone), the Company will fund Durata an additional $15 million (tranche two).

Intellectual Property

Patents

We have been issued patents in the United States and elsewhere, covering the humanization of antibodies, which we refer to as our Queen et al. patents. Our Queen et al. patents, for which final patent expiry is in December 2014, cover, among other things, humanized antibodies, methods for humanizing antibodies, polynucleotide encoding in humanized antibodies and methods of producing humanized antibodies.

Our U.S. Patent No. 5,693,761 (the '761 Patent), which expires on December 2, 2014, covers methods and materials used in the manufacture of humanized antibodies. In addition to covering methods and materials used in the manufacture of humanized antibodies, coverage under our ‘761 Patent will typically extend to the use or sale of compositions made with those methods and/or materials. Genentech has advised us that they believe Lucentis^® is not covered by the claims of the '761 Patent. We have requested clarification from Genentech on the bases of their belief. However, Genentech may elect to stop royalty payments on Lucentis that is manufactured and sold in the United States after June 25, 2013. Genentech has not suggested that Lucentis that is manufactured in the United States prior to June 25, 2013 and sold after that date will not be subject to a royalty payment to us. In addition, our SPCs covering manufacture and/or sale of Lucentis in Europe do not expire until in December 2014.

Our European Patent No. 451 216B (the '216B Patent) expired in Europe in December 2009. We have been granted SPCs for the Avastin^®, Herceptin^®, Lucentis, Xolair^® and Tysabri^® products in many of the jurisdictions in the European Union in connection with the ‘216B Patent. The SPCs effectively extend our patent protection with respect to SPC Products generally until December 2014, except that the SPCs for Herceptin will generally expire in July 2014. Because SPCs are granted on a jurisdiction-by-jurisdiction basis, the duration of the extension varies slightly in certain jurisdictions. We may still be eligible

32

for royalties notwithstanding the unavailability of SPC protection if the relevant royalty-bearing humanized antibody product is also made, used, sold or offered for sale in or imported from a jurisdiction in which we have an unexpired Queen et al. patent such as the United States.

Licensing Agreements

We have entered into licensing agreements under our Queen et al. patents with numerous entities that are independently developing or have developed humanized antibodies. We receive royalties on net sales of products that are made, used and/or sold prior to patent expiry. In general, these agreements cover antibodies targeting antigens specified in the license agreements. Under our licensing agreements, we are entitled to receive a flat-rate or tiered royalty based upon our licensees’ net sales of covered antibodies. We also expect to receive annual maintenance fees from licensees of our Queen et al. patents prior to patent expiry as well as periodic milestone payments. Total annual milestone payments in each of the last several years have been less than 1% of total revenue and we expect this trend will continue through the expiration of the Queen et al. patents.

Licensing Agreements for Marketed Products

In the nine months ended September 30, 2013, we received royalties on sales of the eight humanized antibody products listed below, all of which are currently approved for use by the FDA and other regulatory agencies outside the United States.

Licensee	Product Names
Genentech	Avastin®
	Herceptin®
	Xolair®
	Lucentis®
	Perjeta®
	Kadcyla®
Biogen Idec1	Tysabri®
Chugai	Actemra®

____________________

¹ In April 2013, Biogen Idec completed its purchase of Elan's interest in Tysabri. Prior to this our licensee for Tysabri was identified as Elan.

For the three months ended September 30, 2013 and 2012, we received royalty revenues under license agreements of $96.3 million and $85.2 million, respectively, and for the nine months ended September 30, 2013 and 2012, we received royalty revenues under license agreements of $331.8 million and $288.5 million, respectively.

On February 22, 2013, Genentech announced that the FDA approved Kadcyla^® for second line treatment of HER2-positive metastatic breast cancer and first line treatment for those patients who relapse within six months following adjuvant therapy. Roche has submitted a Marketing Authorization Application to other regulatory authorities around the world, including the EMA, for Kadcyla for the treatment of people with HER2-positive metastatic breast cancer. On September 20, 2013, the EU's Committee for Medicinal Products for Human Use recommended its approval for the treatment of adults with HER2-positive, inoperable locally advanced or metastatic breast cancer who previously received trastuzumab and a taxane, separately or in combination. Also on September 20, 2013, Japan approved it for the same indication. PDL began receiving royalties in the second quarter of 2013 for the sales that occurred in the first quarter of 2013. Because Kadcyla is an antibody drug conjugate, i.e., made up of the antibody, trastuzumab, and the chemotherapy, DM1, joined together using a stable linker, it is a “combination product” under the terms of the license agreement and PDL will not receive royalties on that portion of the sales of the drug attributable to the DM1.

Genentech

We entered into a master patent license agreement, effective September 25, 1998, under which we granted Genentech a license under our Queen et al. patents to make, use and sell certain antibody products. Our license agreement with Genentech entitles us to royalties following the expiration of our patents with respect to sales of licensed product manufactured prior to patent

33

expiry in jurisdictions providing patent protection. Our master patent license agreement with Genentech provides for a tiered royalty structure under which the royalty rate Genentech must pay on royalty-bearing products sold in the United States or manufactured in the United States and used or sold anywhere in the world in a given calendar year decreases on incremental U.S.-based Sales above certain sales thresholds based on 95% of the underlying gross U.S.-based Sales. The net sales thresholds and the applicable royalty rates are outlined below:

Genentech Products Made or Sold in the U.S.	Royalty Rate
Net sales up to $1.5 billion	3.0%
Net sales between $1.5 billion and up to $2.5 billion	2.5%
Net sales between $2.5 billion and up to $4.0 billion	2.0%
Net sales exceeding $4.0 billion	1.0%
Genentech Products Made and Sold ex-U.S.
Net sales	3.0%

As a result of the tiered royalty structure, Genentech’s average annual royalty rate for a given year will decline as Genentech’s U.S.-based Sales increase during that year. Because we receive royalties one quarter in arrears, the average royalty rates for the payments we receive from Genentech for U.S.-based Sales in the second calendar quarter for Genentech’s sales from the first calendar quarter have been and are expected to continue to be higher than the average royalty rates for following quarters. The average royalty rates for payments we receive from Genentech are generally lowest in the fourth and first calendar quarters for Genentech’s sales from the third and fourth calendar quarters when more of Genentech’s U.S.-based Sales bear royalties at the 1% royalty rate.

With respect to ex-U.S.-based Manufacturing and Sales, the royalty rate that we receive from Genentech is a fixed rate of 3.0% based on 95% of the underlying gross sales. The mix of U.S.-based Sales and ex-U.S.-based Manufacturing and Sales has fluctuated in the past and may continue to fluctuate in future periods. The percentage of net global sales that were generated outside of the United States and the percentage of net global sales that were ex-U.S.-based Manufacturing and Sales are outlined in the following table:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2013		2012		2013		2012
Avastin
Ex-U.S.-based Sales	59	%	56	%	58	%	56	%
Ex-U.S.-based Manufacturing and Sales	38	%	29	%	45	%	25	%
Herceptin
Ex-U.S.-based Sales	69	%	70	%	68	%	70	%
Ex-U.S.-based Manufacturing and Sales	38	%	37	%	38	%	38	%

The information in the table above is based on information provided to us by Genentech. We were not provided the reasons for the fluctuations in the manufacturing split between U.S.-based Sales and ex-U.S.-based Manufacturing and Sales.

In the nine months ended September 30, 2013 and 2012, PDL received royalties from ex-U.S. based Manufacturing and Sales of three of Genentech’s licensed products: Herceptin, Avastin and Xolair. Roche, Genentech's parent company, produces Avastin and Herceptin in plants in Basel, Switzerland and Penzberg, Germany, respectively. Roche has announced that there are new plants in Singapore for the potential production of Avastin and Lucentis.

The master patent license agreement continues until the expiration of the last to expire of our Queen et al. patents but may be terminated: (i) by Genentech prior to such expiration upon sixty days written notice, (ii) by either party upon a material breach by the other party or (iii) upon the occurrence of certain bankruptcy-related events.

On June 8, 2012, Genentech announced that the U.S. Food and Drug Administration approved Perjeta (pertuzumab). Perjeta is approved in combination with Herceptin and docetaxel chemotherapy for the treatment of people with HER2-postive metastatic breast cancer who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease. PDL began receiving royalties generated from Perjeta during the quarter ended September 30, 2012.

On March 5, 2013, Genentech announced that Perjeta was approved by the EMA in combination with Herceptin and docetaxel chemotherapy for the treatment of people with HER2-postive metastatic breast cancer who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease.

On September 30, 2013, the FDA granted accelerated approval to Perjeta in combination with Herceptin and other chemotherapy for the treatment of HER2-positive, locally advanced, inflammatory or early stage breast cancer prior to surgery. Perjeta is the first drug approved in this setting.

On February 22, 2013, Genentech announced that the FDA approved Kadcyla for second line treatment of HER2-positive metastatic breast cancer and first line treatment for those patients who relapse within six months following adjuvant therapy. Roche has submitted a Marketing Authorization Application to other regulatory authorities around the world, including the EMA, for Kadcyla for the treatment of people with HER2-positive metastatic breast cancer. On September 20, 2013, the EU's Committee for Medicinal Products for Human Use recommended its approval for the treatment of adults with HER2-positive, inoperable locally advanced or metastatic breast cancer who previously received trastuzumab and a taxane, separately or in combination. Also on September 20, 2013, Japan approved it for the same indication. PDL began receiving royalties in the second quarter of 2013 for the sales that occurred in the first quarter of 2013. Because Kadcyla is an antibody drug conjugate, i.e., made up of the antibody, trastuzumab, and the chemotherapy, DM1, joined together using a stable linker, it is a “combination product” under the terms of the license agreement and PDL will not receive royalties on that portion of the sales of the drug attributable to the DM1.

In 2010 we initiated an audit of Genentech related to its payment of royalties for the period 2007-2009.  KPMG, who Genentech and PDL agreed would be the independent auditor for this purpose, concluded that, based on the information available to it, Genentech may have underpaid royalties during the audited period. Genentech disagrees with KPMG's conclusions. Since we have been unable to resolve this matter with Genentech, we filed a Notice of Arbitration on June 7, 2013, against Genentech alleging that Genentech underpaid royalties going back to at least 2007 and impeded our attempts to have Genentech's books and records inspected to determine whether Genentech's past payments to PDL were accurately calculated. The outcome of this arbitration is uncertain, and we may not be successful in our allegations.

Biogen Idec

We entered into a patent license agreement, effective April 24, 1998, under which we granted to Elan a license under our Queen et al. patents to make, use and sell antibodies that bind to the cellular adhesion molecule α4 in patients with multiple sclerosis. Under the agreement, we are entitled to receive a flat royalty rate in the low single digits based on Elan’s net sales of the Tysabri product. Our license agreement with Elan entitles us to royalties following the expiration of our patents with respect to sales of licensed product manufactured prior to patent expiry in jurisdictions providing patent protection. The agreement continues until the expiration of the last to expire of our Queen et al. patents but may be terminated: (i) by Elan prior to such expiration upon sixty days written notice, (ii) by either party upon a material breach by the other party or (iii) upon the occurrence of certain bankruptcy-related events. In April 2013, Biogen Idec completed its purchase of Elan's interest in Tysabri. All obligations under our original patent license agreement with Elan have been assumed by Biogen Idec.

35

Chugai

We entered into a patent license agreement, effective May 18, 2000, with Chugai, a majority owned subsidiary of Roche, under which we granted to Chugai a license under our Queen et al. patents to make, use and sell antibodies that bind to interleukin-6 receptors to prevent inflammatory cascades involving multiple cell types for the treatment of rheumatoid arthritis. Under the agreement, we are entitled to receive a flat royalty rate in the low single digits based on net sales of the Actemra product manufactured in the U.S. prior to patent expiry. The agreement continues until the expiration of the last to expire of our Queen et al. patents but may be terminated: (i) by Chugai prior to such expiration upon sixty days written notice, (ii) by either party upon a material breach by the other party or (iii) upon the occurrence of certain bankruptcy-related events.

Licensing Agreements for Non-Marketed Products

We have also entered into licensing agreements under which we have licensed certain rights under our Queen et al. patents to make, use and sell certain products that are not currently marketed. Certain of these development-stage products are currently in Phase 3 clinical trials. With respect to these agreements, we may receive payments based on certain development milestones and annual maintenance fees. We may also receive royalty payments if the licensed products receive marketing approval and are manufactured or generate sales before the expiration of our Queen et al. patents. For example, solanezumab is the Lilly licensed antibody for the treatment of Alzheimer's disease. If Lilly’s antibody for Alzheimer’s disease is approved, we would receive royalties on sales of solanezumab manufactured before patent expiration, as well as be entitled to receive a royalty based on a "know-how" license for technology provided in the design of this antibody. Unlike the royalty for the patent license, the two percent royalty payable for "know-how" runs for 12.5 years after the product's initial commercialization.

Economic and Industry-wide Factors

Various economic and industry-wide factors are relevant to us and could affect our business, including changes to laws and interpretation of those laws that protect our intellectual property rights, our licensees ability to obtain or retain regulatory approval for products licensed under our patents, fluctuations in foreign currency exchange rates, the ability to attract, retain and integrate qualified personnel, as well as overall global economic conditions. We actively monitor economic, industry and market factors affecting our business; however, we cannot predict the impact such factors may have on our future results of operations, liquidity and cash flows. See also the “Risk Factors” section of this quarterly report for additional factors that may impact our business and results of operations.

Critical Accounting Policies and Uses of Estimates

During the nine months ended September 30, 2013, there have been no significant changes to our critical accounting policies since those presented in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2012.

Operating Results

Three and nine months ended September 30, 2013, compared to three and nine months ended September 30, 2012

N/M = Not meaningful

Total royalty revenues were $96.3 million and $85.2 million for the three months ended September 30, 2013 and 2012, respectively, and $331.8 million and $288.5 million for the nine months ended September 30, 2013 and 2012, respectively, and

36

consisted of royalties and maintenance fees earned on sales of products under license agreements associated with our Queen et al. patents. Royalty revenue is net of the payments made under our February 2011 settlement agreement with Novartis, which is based on a portion of the royalties that the company receives from Lucentis sales made by Novartis outside the United States. The amount paid is less than we receive in royalties on such sales.

Royalty revenues increased13% for the three months ended September 30, 2013, when compared to the same period in 2012, and increased15% for the nine months ended September 30, 2013, when compared to the same period in 2012. The growth is primarily driven by increased royalties in the first, second and third quarters of 2013 related to sales of Avastin, Herceptin, Lucentis, Xolair, Perjeta, Kadcyla and Actemra by our licensees. Net sales of Avastin, Herceptin, Lucentis, Xolair, Perjeta and Kadcyla are subject to a tiered royalty rate except in the case when the product is ex-U.S. Manufactured and Sold, in which case it is subject to a flat three percent royalty rate.

Total revenues were $97.3 million and $332.8 million for the three and nine months ended September 30, 2013, respectively, and consisted of royalty revenues as well as license and other revenues including a total of $1.0 million in milestone payments from Roche related to obinutuzumab in the period. There were no license and other revenues during the same periods ending September 30, 2012.

The following table summarizes the percentage of our total revenues earned from our licensees’ net product sales that individually accounted for 10% or more of our total revenues for the three and nine months ended September 30, 2013 and 2012:

		Three Months Ended				Nine Months Ended
		September 30,				September 30,
Licensee	Product Name	2013		2012		2013		2012
Genentech	Avastin	33	%	30	%	34	%	31	%
	Herceptin	32	%	36	%	33	%	35	%
	Lucentis	14	%	15	%	17	%	18	%

__________________

¹ In April 2013, Biogen Idec completed its purchase of Elan's interest in Tysabri. Prior to this our licensee for Tysabri was identified as Elan.

Foreign currency exchange rates also impact our reported revenues. More than 50% of our licensees’ product sales are in currencies other than U.S. dollars; as such, our revenues may fluctuate due to changes in foreign currency exchange rates and are subject to foreign currency exchange risk. While foreign currency conversion terms vary by license agreement, generally most agreements require that royalties first be calculated in the currency of sale and then converted into U.S. dollars using the average daily exchange rates for that currency for a specified period at the end of the calendar quarter. Accordingly, when the U.S. dollar weakens against other currencies, the converted amount is greater than it would have been had the U.S. dollar not weakened. For example, in a quarter in which we generate $70 million in royalty revenues, and when approximately $35 million is based on sales in currencies other than U.S. dollar, if the U.S. dollar strengthens across all currencies by ten percent during the conversion period for that quarter, when compared to the same amount of local currency royalties for the prior year, U.S. dollar converted royalties will be approximately $3.5 million less in the current quarter than in the prior year quarter. The impact on full year revenue is greatest in the second quarter when we receive the largest amount of royalties because the Genentech tiered royalties are at their highest rate for first quarter sales.

As a result of our Euro forward contracts, recognized royalty revenues did not increase for the three months ended September 30, 2013 and decreased $0.5 million for the three months ended 2012, and decreased $1.6 million and $1.5 million for the nine months ended September 30, 2013 and 2012, respectively.

Operating Expenses

Percentage of total revenues	8		%	7		%		7		%	6		%

The increase in operating expenses for the three and nine months ended September 30, 2013 compared to the same periods in 2012 was a result of increased legal expenses related to litigation.

Non-operating Expense, Net

For the three months ended September 30, 2013, compared to the three months ended September 30, 2012, non-operating expense, net, decreased primarily due to a $1.0 million increase in interest income from the notes receivables entered into during 2012 and 2013 and $0.4 million lower interest expense as a result of our repayment of the principal balance of our Non-Recourse Notes.

For the nine months ended September 30, 2013, compared to the nine months ended September 30, 2012, non-operating expense, net, decreased primarily due to a $9.3 million increase in interest income from the notes receivables entered into during 2012 and 2013 and $4.9 million lower interest expense as a result of our repayment of the principal balance of our Non-Recourse Notes.

Income Taxes

Income tax expense for the three months ended September 30, 2013 and 2012, was $30.0 million and $26.4 million, respectively, and for the nine months ended September 30, 2013 and 2012, was $101.0 million and $87.8 million, respectively, which resulted primarily from applying the federal statutory income tax rate to income before income taxes.

During the second and third quarters of 2013, the Company released tax liabilities for the federal tax credits taken on the 2009 income tax return, in the amount of $5.7 million and $0.4 million, respectively. This resulted in a reduction to income tax expense for the second and third quarters of 2013. We expect to release additional tax liabilities in the third quarter of 2014 of approximately $7.0 million.

Net Income per Share

Net income per share for the three and nine months ended September 30, 2013 and 2012, was:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2013		2012		2013		2012
Net income per basic share	$	0.40	$	0.35	$	1.45	$	1.16
Net income per diluted share	$	0.36	$	0.32	$	1.31	$	1.08

The increase in the net income per diluted share is due to the increase in royalty revenues and the resulting increase in net income.

Liquidity and Capital Resources

We finance our operations primarily through royalty and other license related revenues, public and private placements of debt and equity securities and interest income on invested capital. We currently have fewer than ten employees managing our intellectual property, our licensing operations and other corporate activities as well as providing for certain essential reporting and management functions of a public company.

38

We had cash, cash equivalents and investments in the aggregate of $326.5 million and $148.7 million, excluding restricted investments, at September 30, 2013, and December 31, 2012, respectively. The increase was primarily attributable to net cash provided by operating activities of $209.7 million and repayment of notes receivable of $58.1 million, offset in part by payment of dividends of $62.9 million and cash advanced on notes receivable of $48.7 million. We believe that cash from future royalty revenues, net of operating expenses, debt service and income taxes, plus cash on hand, will be sufficient to fund our operations over the next several years. The last of our Queen et al. patents expires in December 2014, with the obligation to pay royalties under various license agreements expiring sometime thereafter, and we do not expect to receive any meaningful revenue from the inventories produced prior to the expiration of our Queen et al. patents beyond the first quarter of 2016.

We continuously evaluate alternatives to increase return for our stockholders by, for example, purchasing income generating assets, buying back our convertible notes, repurchasing our common stock, paying dividends and selling the Company. On January 23, 2013, our board of directors declared regular quarterly dividends of $0.15 per share of common stock, payable on March 12, June 12, September 12 and December 12 of 2013 to stockholders of record on March 5, June 5, September 5 and December 5 of 2013, the record dates for each of the dividend payments, respectively.

Notes and Other Long-term Receivables

Wellstat Diagnostics Note Receivable and Credit Agreement

In March 2012, the Company executed a $7.5 milliontwo-year senior secured note receivable with the holders of the equity interests in Wellstat Diagnostics. In addition to bearing interest at 10% per annum, the note gave PDL certain rights to negotiate for certain future financing transactions. In August 2012, PDL and the borrowers amended the note receivable, providing a senior secured note receivable of $10.0 million, bearing interest at 12% per annum, to replace the original $7.5 million note. This $10.0 million note was repaid on November 2, 2012.

On November 2, 2012, the Company and Wellstat Diagnostics entered into a $40.0 million credit agreement pursuant to which the Company is to accrue quarterly interest payments at the rate of 5% per annum (payable in cash or in kind). In addition, PDL will receive quarterly royalty payments based on a low double digit royalty rate of Wellstat Diagnostics' net revenues, generated by the sale, distribution or other use of Wellstat Diagnostics' products, if any, commencing upon the commercialization of its products.

In January 2013, the Company was informed that, as of November 2012, Wellstat Diagnostics had used funds contrary to the terms of the credit agreement and breached Sections 2.1.2 and 7 of the credit agreement. PDL sent Wellstat Diagnostics a notice of default on January 22, 2013, and accelerated the amounts owed under the credit agreement. In connection with the notice of default, PDL exercised one of its available remedies and transferred approximately $8.1 million of available cash from a bank account of Wellstat Diagnostics to PDL and applied the funds to amounts due under the credit agreement. On February 28, 2013, the parties entered into a forbearance agreement whereby PDL agreed to refrain from exercising additional remedies for 120 days while Wellstat Diagnostics raised funds to capitalize the business and the parties attempted to negotiate a revised credit agreement. PDL agreed to provide up to $7.9 million to Wellstat Diagnostics to fund the business for the 120-day forbearance period under the terms of the forbearance agreement. Following the conclusion of the June 28 forbearance period, the Company agreed to forbear in its exercise of remedies for additional periods of time to allow the owners and affiliates of Wellstat Diagnostics to complete a pending financing transaction. During such forbearance period, the Company provided approximately $1.3 million to Wellstat Diagnostics to fund ongoing operations of the business. During the nine months endedSeptember 30, 2013, approximately $8.7 million was advanced pursuant to the forbearance agreement.

On August 15, 2013, the owners and affiliates of Wellstat Diagnostics completed a financing transaction to fulfill its obligations under the forbearance agreement. On August 15, 2013, the Company entered into an amended and restated credit agreement with Wellstat Diagnostics. The Company determined that the new agreement should be accounted for as a modification of the existing agreement.

Except as otherwise described here, the material terms of the amended credit agreement are substantially the same as those of the original credit agreement, including quarterly interest payments at the rate of 5% per annum (payable in cash or in kind). In addition, PDL will continue to receive quarterly royalty payments based on a low double digit royalty rate of Wellstat Diagnostics' net revenues. However, pursuant to the amended credit agreement: (i) the principal amount was reset to approximately $44.1 million which was comprised of approximately $33.7 million original loan principal and interest, $1.3 million term loan principal and interest and $9.1 million forbearance principal and interest; (ii) the specified internal rates of return increased; (iii) the default interest rate was increased; (iv) Wellstat Diagnostics' obligation to provide certain financial information increased in frequency to monthly; (v) internal financial controls were strengthened by requiring Wellstat Diagnostics to maintain an independent, third-party financial professional with control over fund disbursements; (vi) the

39

Company waived the existing events of default; and (vii) the owners and affiliates of Wellstat Diagnostics are required to contribute additional capital to Wellstat Diagnostics upon the sale of an affiliate entity. The restated credit agreement continues to have an ultimate maturity date of December 31, 2021 (but may mature earlier upon certain specified events).

Wellstat Diagnostics may prepay the amended credit agreement at a price that, together with interest and royalty payments already made to the Company, would generate a specified internal rate of return to the Company. In the event of a change of control, bankruptcy or certain other customary events of defaults, or Wellstat Diagnostics' failure to achieve a specified annual revenue threshold in 2017, Wellstat Diagnostics will be required to prepay the credit agreement at a price that, together with interest and royalty payments already made to the Company, would generate a specified internal rate of return to the Company. The amended credit agreement is secured by a pledge of all of the assets of Wellstat Diagnostics, a pledge of all of Wellstat Diagnostics’ equity interests by the holders thereof, and a second lien on the assets of the affiliates of Wellstat Diagnostics.The Company believes the fair value of the collateral is not less than$76.6 million.

At September 30, 2013, the carrying value of the note was included in non-current assets.

Merus Labs Receivable and Credit Agreement

In July 2012, PDL loaned $35.0 million to Merus Labs in connection with its acquisition of a commercial-stage pharmaceutical product and related assets. In addition, PDL agreed to provide a $20.0 million letter of credit on behalf of Merus Labs for the seller of the assets to draw upon to satisfy the remaining $20.0 million purchase price obligation. The seller made this draw on the letter of credit in July of 2013 and an additional loan to Merus Labs for $20.0 million was recorded for an aggregate of $55.0 million in total borrowings.

Outstanding borrowings under the July 2012 loan bore interest at the rate of 13.5% per annum and outstanding borrowings as a result of the draw on the letter of credit bore interest at the rate of 14.0% per annum. Merus Labs was required to make four periodic principal payments in respect of the July 2012 loan, with repayment of the remaining principal balance of all loans due on March 31, 2015. The borrowings were subject to mandatory prepayments upon certain asset dispositions or debt issuances as set forth in the credit agreement. Merus Labs made the first of these payments in December 2012 in the amount of $5.0 million, and made the second payment in June 2013 in the amount of $7.5 million. In September 2013, Merus Labs made two additional payments totaling $43.3 million, including the prepayment fee, in order to pay its remaining outstanding balance. In September 2013, Merus Labs prepaid its entire outstanding balance, including accrued interest through the payment date and a prepayment penalty. There was no outstanding balance as of September 30, 2013.

AxoGen Note Receivable and Royalty Agreement

In October 2012, PDL entered into the Royalty Agreement with AxoGen pursuant to which the Company 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 royalties of 9.95% based on AxoGen Net Revenues, subject to agreed-upon guaranteed quarterly minimum payments of approximately $1.3 to $2.3 million beginning in the fourth quarter of 2014, and the right to require AxoGen to repurchase the Royalty Agreement at the end of the fourth year. AxoGen has been granted certain rights to call the 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.

Under the Royalty Agreement, beginning on October 1, 2016, or in the event of the occurrence of a material adverse event or AxoGen's bankruptcy or material breach of the Royalty Agreement, the Company may require AxoGen to repurchase the royalty rights at a price that, together with payments already made by AxoGen, would generate a specified internal rate of return to the Company. The Company has concluded that the repurchase option is an embedded derivative which should be bifurcated and separately recorded at fair value. The fair value of the repurchase option was not material on September 30, 2013.

In the event of a change of control, AxoGen must repurchase the assigned interests from the Company for a repurchase price equal to an amount that, together with payments already made by AxoGen, would generate a 32.5% internal rate of return to the Company. The Company has concluded that the change of control provision is an embedded derivative that should be bifurcated and separately accounted for at fair value. The estimated fair value of the change of control provision was approximately $1.0 million on September 30, 2013.

40

In addition, at any time after September 30, 2016, AxoGen, at its option, can repurchase the assigned interests under the Royalty Agreement for a price applicable in a change of control.

On August 14, 2013, PDL purchased 1,166,666 shares of AXGN at $3.00 per share, totaling $3.5 million. The shares are classified as available for sale and recorded as short term investments on the balance sheet. As of September 30, 2013, the shares were valued at $5.2 million, which results in an unrealized gain of $1.7 million and is recorded in other comprehensive income.

Avinger Credit and Royalty Agreement

On April 18, 2013, PDL entered into a credit agreement with Avinger, under which we made available to Avinger up to $40.0 million to be used by Avinger in connection with the commercialization of its currently marketed lumivascular catheter devices and in the development of Avinger's lumivascular atherectomy device. Of the $40.0 million available to Avinger, we funded an initial $20.0 million, net of fees, at close of the transaction. Upon the attainment of a certain revenue milestone to be accomplished no later than the end of the first half of 2014, we will fund Avinger an additional amount between $10.0 million and $20.0 million (net of fees) at Avinger's election. Outstanding borrowings under the initial loan bear interest at the rate of 12% per annum, and outstanding borrowings as a result of an additional amount funded upon reaching the revenue milestone bear interest at the rate of 14% per annum.

Avinger is required to make quarterly interest and principal payments. Principal repayment will commence on: (i) the eleventh interest payment date if the revenue milestone is not achieved or (ii) the thirteenth interest payment date if the revenue milestone is achieved. The principal amount outstanding at commencement of repayment, after taking into account any payment-in-kind, will be repaid in equal installments until final maturity of the loans. The loans will mature in April 2018.

In connection with entering into the credit agreement, the Company will receive a low, single-digit royalty on Avinger's net revenues through April 2018. Avinger may prepay the outstanding principal and accrued interest on the note receivable at any time. If Avinger repays the note receivable prior to April 2018, the royalty on Avinger's net revenues will be reduced by 50% and will be subject to certain minimum payments from the prepayment date through April 2018.

The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Avinger and any of its subsidiaries (other than controlled foreign corporations, if any). The credit agreement provides for a number of standard events of default, including payment, bankruptcy, covenant, representation and warranty and judgment defaults.

Convertible Notes

Series 2012 Notes

In January 2012, we exchanged $169.0 million aggregate principal amount of our February 2015 Notes, for an identical principal amount of new Series 2012 Notes, plus a cash payment of $5.00 for each $1,000 principal amount tendered for a total cash incentive payment of approximately $0.8 million. Additionally, in February 2012, we entered into separate privately negotiated exchange agreements under which we exchanged an additional $10.0 million aggregate principal amount of our February 2015 Notes for an identical principal amount of our new Series 2012 Notes. In August 2013, the Company entered into a separate privately negotiated exchange agreement under which it retired the final $1.0 million aggregate principal amount of the Company's outstanding February 2015 Notes. Pursuant to the exchange agreement, the holder of the February 2015 Notes received $1.0 million aggregate principal amount of the Company's Series 2012 Notes. Immediately following the exchange, no principal amount of the February 2015 Notes remained outstanding and $180.0 million principal amount of the Series 2012 Notes is outstanding. Our Series 2012 Notes net share settle, 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.

Our Series 2012 Notes bear interest at a rate of 2.875% per annum, payable semiannually in arrears on February 15 and August 15 of each year, beginning on February 15, 2012. The Series 2012 Notes mature on February 15, 2015, unless earlier repurchased or converted. The Company may not redeem the Series 2012 Notes prior to their stated maturity date. Our Series 2012 Notes are not puttable by the note holders other than in the context of a fundamental change resulting in the reclassification, conversion, exchange or cancellation of our common stock. Such repurchase event or 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.

41

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.

Upon conversion of Series 2012 Notes, the Company will be required to pay cash and, if applicable, deliver shares of the Company’s common stock. Our Series 2012 Notes are convertible into 179.777 shares of the Company’s common stock per $1,000 of principal amount or approximately $5.56 per share of our common stock, subject to further adjustment upon certain events including dividend payments. As of September 30, 2013, $180.0 million of our Series 2012 Notes were outstanding and the if-converted value exceeded the principal amount by approximately $77.9 million. Our common stock did exceed the conversion threshold price of $7.37 for at least 20 days during the 30 consecutive trading days ended June 30, 2013; accordingly, the Series 2012 Notes were convertible at the option of the holder during the quarter ended September 30, 2013. Our common stock did exceed the conversion threshold price of $7.23 for at least 20 days during the 30 consecutive trading days ended September 30, 2013; accordingly, the Series 2012 Notes are convertible at the option of the holder during the quarter ending December 31, 2013. In the second quarter of 2013, the Series 2012 Notes have been reclassified from non-current to current as the notes will be due upon demand within one year of the quarter end September 30, 2013.

As of November 4, 2013, we have not received notices for the conversion of the Series 2012 Notes. If we do receive any conversion notices they would be net settled in cash and the excess, if any, will be settled in the Company's common stock. We do not expect the current capital market conditions and credit environment to create incentives for note holders to convert their notes, however, there can be no assurance that our holders will not request conversion. If the full $180.0 million in aggregate convertible debt was called for conversion prior to December 31, 2013, given our current cash and cash equivalents balance, we would have sufficient unrestricted cash and cash equivalents on hand to satisfy the conversion without additional liquidity. We may also consider restructuring our obligations under the convertible debt, or raising additional cash through sales of investments, assets or common stock, or from borrowings to fund this conversion.

May 2015 Notes

Our May 2015 Notes are due May 1, 2015, and bear interest at a rate of 3.75% per annum, payable semiannually in arrears on May 1 and November 1 of each year, beginning November 1, 2011. Upon the occurrence of a fundamental change, as defined in the indenture, holders have the option to require PDL to repurchase their May 2015 Notes at a purchase price equal to 100% of the principal, plus accrued interest. Our May 2015 Notes are convertible under any of the following circumstances:

• During any fiscal quarter commencing after the fiscal quarter ending June 30, 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, which we refer to as the measurement period, in which the trading price per $1,000 principal amount of notes for each trading day of that measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the notes for each such day;

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

• Anytime, on or after November 1, 2014.

Upon conversion of the May 2015 Notes, the Company will be required to pay cash, and if applicable, deliver shares of the Company’s common stock. Our May 2015 Notes are convertible into 157.3700 shares of the Company’s common stock per $1,000 of principal amount, or approximately $6.35 per share of our common stock, subject to further adjustment upon certain

42

events including dividend payments. As of September 30, 2013, $155.3 million of our May 2015 Notes were outstanding and the if-converted value exceeded the principal amount by approximately $39.5 million. However, our common stock price did not exceed the threshold price of $8.42 per common share for at least 20 days during the 30 consecutive trading days ended June 30, 2013; accordingly, the May 2015 Notes were not convertible at the option of the holder during the quarter ended September 30, 2013. Our common stock did not exceed the conversion threshold price of $8.26 for at least 20 days during the 30 consecutive trading days ended September 30, 2013; accordingly, the May 2015 Notes are not convertible at the option of

the holder during the quarter ending December 31, 2013.

Purchased Call Options and Warrants

In connection with the issuance of our May 2015 Notes, we entered into purchased call option transactions with two hedge counterparties. We paid an aggregate amount of $20.8 million, plus legal fees, for the purchased call options with terms substantially similar to the embedded conversion options in our May 2015 Notes. The purchased call options cover, subject to anti-dilution and certain other customary adjustments substantially similar to those in our May 2015 Notes, approximately 24.4 million shares of our common stock at a strike price of approximately $6.35, which corresponds to the conversion price of our May 2015 Notes. 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. The purchased call options expire on May 1, 2015, or the last day any of our May 2015 Notes remain outstanding.

In addition, we sold to the hedge counterparties warrants exercisable, on a cashless basis, for the sale of rights to receive up to 27.5 million shares of common stock underlying our May 2015 Notes, at a current strike price of approximately $7.48 per share, subject to additional anti-dilution and certain other customary adjustments. We received an aggregate amount of $10.9 million for the sale from the two counterparties. The warrant counterparties may exercise the warrants on their specified expiration dates that occur over a period of time ending on January 20, 2016. If the VWAP of our common stock, as defined in the warrants, exceeds the strike price of the warrants, we will deliver to the warrant counterparties shares equal to the spread between the VWAP on the date of exercise or expiration and the strike price. If the VWAP is less than the strike price, neither party is obligated to deliver anything to the other.

The purchased call option transactions and warrant sales effectively serve to reduce the potential dilution associated with conversion of our May 2015 Notes.

If the share price is above $6.35, but below $7.48, upon conversion of our May 2015 Notes, the purchased call options will offset the share dilution, because the Company will receive shares on exercise of the purchased call options equal to the shares that the Company must deliver to the note holders. If the share price is above $7.48, upon exercise of the warrants, the Company will deliver shares to the counterparties in an amount equal to the excess of the share price over $7.48. For example, a 10% increase in the share price above $7.48 would result in the issuance of 1.9 million incremental shares upon exercise of the warrants. As our share price continues to increase, additional dilution would occur.

While the purchased call options are expected to reduce the potential equity dilution upon conversion of our May 2015 Notes, prior to conversion or exercise, our May 2015 Notes and the warrants could have a dilutive effect on the Company's earnings per share to the extent that the price of the Company's common stock during a given measurement period exceeds the respective exercise prices of those instruments. As of September 30, 2013, the market price condition for convertibility of our May 2015 Notes was not met and there were no related purchased call options or warrants exercised.

The purchased call options and warrants are considered indexed to PDL stock, require net-share settlement, and met all criteria for equity classification at inception and at September 30, 2013, and December 31, 2012. The purchased call options cost, including legal fees, $20.8 million, less deferred taxes of $7.2 million, and the $10.9 million received for the warrants were recorded as adjustments to additional paid-in capital. Subsequent changes in fair value will not be recognized as long as the purchased call options and warrants continue to meet the criteria for equity classification.

Off-Balance Sheet Arrangements

As of September 30, 2013, we did not have any off-balance sheet arrangements, as defined under SEC Regulation S-K Item 303(a)(4)(ii).

43

Contractual Obligations

Convertible Notes

As of September 30, 2013, our contractual obligations consisted primarily of our Series 2012 Notes and May 2015 Notes, which in the aggregate totaled $335.3 million in principal. Our Series 2012 and our May 2015 Notes are not puttable by the note holders other than in the context of a fundamental change.

We expect that our debt service obligations over the next several years will consist of interest payments and repayment of our Series 2012 Notes and our May 2015 Notes. We may further seek to exchange, repurchase or otherwise acquire the convertible notes in the open market in the future which could adversely affect the amount or timing of any distributions to our stockholders. We would make such exchanges or repurchases only if we deemed it to be in our stockholders’ best interest. We may finance such repurchases with cash on hand and/or with public or private equity or debt financings if we deem such financings are available on favorable terms.

Notes Receivable and Other Long Term Receivables

On April 18, 2013, PDL entered into a credit agreement with Avinger, under which we made available to Avinger up to $40.0 million to be used by Avinger in connection with the commercialization of its currently marketed lumivascular catheter devices and in the development of Avinger's lumivascular atherectomy device. Of the $40.0 million available to Avinger, we funded an initial $20.0 million, net of fees, at close of the transaction. Upon the attainment of certain revenue milestones to be accomplished no later than the end of the first half of 2014, we will fund Avinger an additional amount between $10.0 million and $20.0 million (net of fees) at Avinger's election.

On October 1, 2013, PDL entered into a credit agreement with LENSAR, under which PDL made available to LENSAR up to $60 million to be used by LENSAR in connection with the commercialization of its currently marketed LENSAR Laser System. Of the $60 million available to LENSAR, an initial $40 million, net of fees, was funded by PDL at close of the transaction. Upon the attainment by LENSAR of a specified sales milestone to be accomplished no later than September 30, 2014, PDL will fund LENSAR an additional $20 million. Outstanding borrowings under the loans bear interest at the rate of 15.5% per annum, payable quarterly in arrears.

On October 31, 2013, PDL entered into a credit agreement with Durata, whereby the Company made available to Durata up to $70.0 million. Of the $70.0 million available to Durata, an initial $25.0 million (tranche one), net of fees, was funded by the Company at the close of the transaction.Upon marketing approval of dalbavancin in the United States, to be accomplished no later than December 31, 2014 (the tranche two milestone), the Company will fund Durata an additional $15 million (tranche two). Within 9 months after the occurrence of the tranche two milestone, Durata may request up to a single additional $30 million borrowing.

On November 5, 2013, PDL entered into a credit agreement with Direct Flow Medical, in which PDL will provide up to $50.0 million to Direct Flow Medical. Of the $50.0 million available to Direct Flow Medical, an initial $35.0 million, net of fees, was provided by the company at the close of the transaction. Upon the attainment of a specified revenue milestone to be accomplished no later than December 31, 2014, the Company will loan to Direct Flow Medical an additional $15.0 million, net of fees.

Lease Guarantee

In connection with the Spin-Off, we entered into amendments to the leases for our former facilities in Redwood City, California, under which Facet was added as a co-tenant, 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 could 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, 2013, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately $92.7 million. If Facet were to default, we could 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. We have recorded a liability of $10.7 million on our Condensed Consolidated Balance Sheets as of September 30, 2013, and December 31, 2012, related to this guarantee.

44

Indemnification

As permitted under Delaware law and under the terms of our bylaws, the Company has entered into indemnification agreements with its directors and executive officers. Under these agreements, the Company has agreed to indemnify such individuals for certain events or occurrences, subject to certain limits, against liabilities that arise by reason of their status as directors or officers and to advance expense incurred by such individuals in connection with related legal proceedings. While the maximum amount of potential future indemnification is unlimited, we have a director and officer insurance policy that limits our exposure and may enable us to recover a portion of any future amounts paid.

45

ITEM 3.      QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Risk

The underlying sales of our licensees’ products are conducted in multiple countries and in multiple currencies throughout the world. While foreign currency conversion terms vary by license agreement, generally most agreements require that royalties first be calculated in the currency of sale and then converted into U.S. dollars using the average daily exchange rates for that currency for a specified period at the end of the calendar quarter. Accordingly, when the U.S. dollar weakens in relation to other currencies, the converted amount is greater than it would have been had the U.S. dollar not weakened. More than 50% of our licensees’ product sales are in currencies other than U.S. dollars; as such, our revenues may fluctuate due to changes in foreign currency exchange rates and are subject to foreign currency exchange risk. For example, in a quarter in which we generate $70 million in royalty revenues, and when approximately $35 million is based on sales in currencies other than the U.S. dollar, if the U.S. dollar strengthens across all currencies by 10% during the conversion period for that quarter, when compared to the same amount of local currency royalties for the prior year, U.S. dollar converted royalties will be approximately $3.5 million less in that current quarter sales, assuming that the currency risk in such forecasted sales was not hedged.

We hedge Euro-denominated risk exposures related to our licensees’ product sales with Euro forward contracts. In general, these contracts are intended to offset the underlying Euro market risk in our royalty revenues. Our current contracts extend through the fourth quarter of 2014 and are all classified for accounting purposes as cash flow hedges. We continue to monitor the change in the Euro exchange rate and regularly purchase additional forward contracts to achieve hedged rates that approximate the average exchange rate of the Euro over the year, which we anticipate will better offset potential changes in exchange rates than simply entering into larger contracts at a single point in time.

In January 2012, we modified our existing Euro forward and option contracts related to our licensees’ sales through December 2012 into forward contracts with more favorable rates than the rate that was ensured by the previous contracts. 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. In August 2012, we de-designated and terminated certain forward contracts, recording a gain of approximately $391,000 in interest and other income, net. The termination of these contracts was effected through a reduction in the notional amount of the original hedge contracts that 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.

Gains or losses on our cash flow hedges are recognized in the same period that the hedged transaction impacts earnings as an adjustment to royalty revenue. Ineffectiveness, if any, resulting from the change in fair value of the modified 2012 hedge or lower than forecasted Euro-based royalties will be reclassified from other comprehensive income (loss) and recorded as interest and other income, net, in the period it occurs. The following table summarizes the notional amounts, Euro exchange rates and fair values of our outstanding Euro contracts designated as hedges at September 30, 2013, and December 31, 2012:

Euro Forward Contracts			September 30, 2013					December 31, 2012
			(In thousands)					(In thousands)
Currency	Settlement Price	Type	Notional Amount		Fair Value			Notional Amount		Fair Value
	($ per Euro)
Euro	1.230	Sell Euro	$	—	$	—		$	27,553	$	(2,036	)
Euro	1.240	Sell Euro	10,850		(982		)	10,850		(726		)
Euro	1.270	Sell Euro	44,450		(2,887		)	44,450		(1,950		)

Total			$	131,114	$	(7,508	)	$	210,667	$	(7,581	)

Interest Rate Risk

Our investment portfolio was approximately $276.7 million at September 30, 2013, and $140.8 million at December 31, 2012, and consisted of investments in Rule 2a-7 money market funds, certificates of deposit and corporate debt securities. If market

46

interest rates were to have increased by 1% in either of these years, there would have been no material impact on the fair value of our portfolio.

The aggregate fair value of our convertible notes was estimated to be $457.1 million at September 30, 2013, and $410.5 million at December 31, 2012, based on available pricing information. At September 30, 2013, and December 31, 2012, our convertible notes consisted of our Series 2012 Notes, with a fixed interest rate of 2.875%, and our May 2015 Notes, with a fixed interest rate of 3.75%. These obligations are subject to interest rate risk because the fixed interest rates under these obligations may exceed current market interest rates.

47

ITEM 4.        CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of September 30, 2013, our disclosure controls and procedures were effective to ensure the information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in Internal Controls

There were no changes in our internal controls over financial reporting during the quarter ended September 30, 2013, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within an organization have been detected. We continue to improve and refine our internal controls and our compliance with existing controls is an ongoing process.

PART II. OTHER INFORMATION

ITEM 1.           LEGAL PROCEEDINGS

Genentech / Roche Matter

Communications with Genentech regarding European SPCs

In August 2010, we received a letter from Genentech, sent on behalf of Roche and Novartis, asserting that the Avastin, Herceptin, Lucentis and Xolair do not infringe the SPCs granted to PDL by various countries in Europe for covering those 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 Avastin, Herceptin, Lucentis and Xolair. The SPCs covering the Avastin, Herceptin, Lucentis and Xolair effectively extend our European patent protection for the '216B Patent generally until December 2014, except that the SPCs for Herceptin will generally expire in July 2014.

Genentech’s letter does not suggest that any of the Genentech Products do not infringe PDL’s U.S. patents to the extent that such Genentech Products are U.S.-based Sales. Genentech’s quarterly royalty payments received after receipt of the letter have 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 Avastin, Herceptin, Lucentis and Xolair that are both manufactured and sold outside of the United States. Royalties on sales of Avastin, Herceptin, Lucentis and Xolair that are ex-U.S.-based Manufacturing and Sales accounted for approximately 42% of our royalty revenues for the nine months ended September 30, 2013.

We believe that the SPCs are enforceable, 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 and Arbitration with Genentech

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 Avastin, Herceptin, Lucentis and Xolair.

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.

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 parties have been engaged in discovery motion practice. On March 29, 2013, the court affirmed an order of the discovery commissioner requiring the production of certain documents in the possession of Roche and Genentech to PDL. Roche and Genentech have communicated to us that they have requested review of the court's order from the Nevada Supreme Court. The parties have agreed to a stay in the proceedings pending the decision of the Nevada Supreme Court regarding whether they will review the court's order. In the event that the Nevada Supreme Court agrees to consider Roche and Genentech's request and review the court's order, we expect a lengthy delay in the case schedule for a period that may extend for a number of months, and, while no trial date is currently scheduled with the District Court, the likelihood is that a trial date will be at some point between mid-2014 to mid-2015. The outcome of this litigation is uncertain and we may not be successful in our allegations.

49

On June 7, 2013, the Company filed a Notice of Arbitration against Genentech with the American Arbitration Association in Voorhees, New Jersey, alleging, inter alia, that Genentech underpaid royalties going back to at least 2007 and impeded PDL's attempts to have Genentech's books and records inspected to determine whether Genentech's past payments to PDL were accurately calculated.

In 2009, PDL retained KPMG to conduct an independent inspection and analysis of the books and records of Genentech and its sublicensees for the three year period covering January 1, 2007 to December 31, 2009, a right granted to PDL under PDL's Patent License Master Agreement and license agreements with Genentech. KPMG reported to PDL that, due to limitations on its inspection imposed by Genentech, it was unable to assess the completeness or accuracy of Genentech's reporting of royalties. KPMG concluded that, based on the limited information it was able to review, Genentech appears to have underpaid PDL in an amount that, if substantiated, PDL believes would be material. Genentech has informed PDL that it disagrees with KPMG's conclusions and that it believes that it has correctly calculated royalties due.

In the arbitration, PDL: (i) requests a declaration of the parties' rights and obligations with respect to reporting and payment of royalties under the license agreements; (ii) alleges that Genentech has breached the license agreements due to its obstruction of KPMG's inspection and underpayment of royalties; and (iii) alleges that Genentech breached the implied covenant of good faith and fair dealing by depriving PDL of the benefits of the license agreements through its obstruction of the inspection, which we further assert concealed the nature and extent of its underpayment.

On July 3, 2013, Genentech filed its Response and Counterclaim in which Genentech requests that the arbitrator (i) reject PDL's claims that Genentech breached the license agreements by underpaying royalties owed to PDL, obstructing KPMG's inspection, or violating the covenant of good faith and fair dealing; (ii) reject PDL's claim that Genentech owed any royalties to PDL on Herceptin, Avastin and Xolair manufactured and sold outside of the United States prior to December 27, 2009 on the ground that those products did not infringe the '216B patent prior to its expiration; (iii) offset any royalties underpaid during the audit period by the amount Genentech claims to have overpaid in royalties attributable to the sale of Herceptin, Avastin and Xolair manufactured and sold outside of the United States prior to December 27, 2009; and (iv) award damages to Genentech in the amount of $428,751, representing royalties Genentech overpaid during the audit period, as well as costs and reasonable attorney's fees. Genentech's counterclaim does not challenge whether Herceptin, Avastin and Xolair manufactured and sold outside of the United States after December 27, 2009, are Licensed Products (and subject to a royalty under PDL's SPCs issued to such products in Europe) as Genentech's ability to contest infringement of PDL's SPCs is the subject of pending litigation in Nevada.

The parties have mutually agreed to stay the arbitration proceedings and to extend the deadline for responses in the Nevada litigation to allow time for discussions to occur to determine if a settlement of certain issues is possible. The parties may not reach agreement regarding settlement terms and PDL expects that it will renew its litigation efforts if settlement is unsuccessful.

The outcome of this arbitration is uncertain, and PDL may not be successful in its allegations.

Other Legal Proceedings

In addition, from time to time, we are subject to various other legal proceedings and claims that arise in the ordinary course of business and which we do not expect to materially impact our financial statements.

ITEM 1A.        RISK FACTORS

Except as set forth below, during the nine months ended September 30, 2013, there were no material changes to the risk factors included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012. Please carefully consider the information set forth in this Quarterly Report on Form 10-Q and the risk factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2012, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K, as well as other risks and uncertainties, could materially and adversely affect our business, results of operations and financial condition, which in turn could materially and adversely affect the trading price of shares of our common stock. Additional risks not currently known or currently material to us may also harm our business.

We depend on our licensees for the determination of royalty payments. While we have rights to audit our licensees and borrowers, the independent auditors may have difficultly determining the correct royalty calculation, we may not be able to detect errors and payment calculations may call for retroactive adjustments. We may have to exercise legal remedies to resolve any disputes resulting from the audit.

The royalty payments we receive are determined by our licensees based on their reported sales. Each licensee's calculation of the royalty payments is subject to and dependent upon the adequacy and accuracy of its sales and accounting functions, and errors may occur from time to time in the calculations made by a licensee. Our license and credit agreements provide us the right to audit the calculations and sales data for the associated royalty payments; however, such audits may occur many months following our recognition of the royalty revenue, may require us to adjust our royalty revenues in later periods and may require expense on the part of the Company.  Further, our licensees and borrowers may be uncooperative or have insufficient records, which may complicate and delay the audit process.

Although we regularly exercise our royalty audit rights, we rely in the first instance on our licensees to accurately report sales and calculate and pay applicable royalties and, upon exercise of such royalty audit rights, we rely on licensees' cooperation in performing such audits. In the absence of such cooperation, we may be forced to exercise legal remedies to enforce our agreements. For example, after a protracted audit of our licensee, Genentech, we initiated an arbitration procedure to resolve disputes over Genentech's cooperation and the underpayment of royalties as reported to us by the independent auditor.

5.17.Intellectual Property. Each Loan Party owns, or is licensed or otherwise has the right to use, all Intellectual Property necessary to conduct its business as currently conducted except for such Intellectual Property the failure of which to own or have a license or other right to use would not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect.

Each Lender irrevocably authorizes the Agent, at its option and in its discretion, to release any Lien granted to or held by the Agent under any Collateral Document (i) when all Obligations have been Paid in Full; (ii) constituting property sold or to be sold or disposed of as part of or in connection with any sale or other disposition permitted hereunder (it being agreed and understood that the Agent may conclusively rely without further inquiry on a certificate of an officer of the Borrower as to the sale or other disposition of property being made in compliance with this Agreement); or (iii) subject to Section 10.1, if approved, authorized or ratified in writing by the Lender. Upon request by the Agent at any time, the Lender will confirm in writing the Agent’s authority to release types or items of Collateral pursuant to this Section 9.5. The Agent shall have the right, in accordance with the Collateral Documents, to sell, lease or otherwise dispose of any Collateral for cash, credit or any combination thereof, and the Agent may purchase any Collateral at public or, if permitted by law, private sale and, in lieu of actual payment of the purchase price, may credit bid and setoff the amount of such price against the Obligations.

Section 10. Miscellaneous.

10.1.Waiver; Amendments. No delay on the part of the Agent or the Lender in the exercise of any right, power or remedy shall operate as a waiver thereof, nor shall any single or partial exercise by any of them of any right, power or remedy preclude other or further exercise thereof, or the exercise of any other right, power or remedy. No amendment, modification or waiver of, or consent with respect to, any provision of this Agreement, the Notes or any of the other Loan Documents (or any subordination and intercreditor agreement or other subordination provisions relating to any other Debt) shall in any event be effective unless the same shall be in writing and approved by the Agent and the Lender, and then any such amendment, modification, waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No provision of Section 9 or other provision of this Agreement affecting the Agent in its capacity as such shall be amended, modified or waived without the consent of the Agent.

10.3.Costs; Expenses.

In addition, the parties agree that in the event that the Agent or Lender determines pursuant to any audit of the books and records of the Borrower and its Subsidiaries conducted pursuant to Section 6.2 that the aggregate amount paid to the Lender hereunder during any period covered by such audit was less than the aggregate amount that was in fact due and payable in respect of such period and the amount of such shortfall exceeds five percent (5%) of the amount that was due and payable, then all Audit Costs in respect of such audit shall be borne by the Borrower and reimbursed to the Agent or Lender, as applicable, and in all other cases, such Audit Costs shall be borne by the Agent or Lender conducting such audit. All Obligations provided for in this Section 10.3 shall survive repayment of the Loans, cancellation of the Notes and termination of this Agreement.

10.4.Indemnification by the Borrower. In consideration of the execution and delivery of this Agreement by the Agent and the Lender and the agreement to extend the Commitments provided hereunder, the Borrower hereby agrees to indemnify, exonerate and hold the Agent, the Lender and each of the officers, directors, employees, Affiliates, controlling persons, advisors and agents of the Agent and the Lender (each a “Lender Party”) free and harmless from and against any and all actions, causes of action, suits, losses, liabilities (including, without limitation, strict liabilities), obligations, damages, penalties, judgments, fines, disbursements, expenses and costs, including Legal Costs (collectively, the “Indemnified Liabilities”), incurred by the Lender Parties or asserted against the Lender Party by any Person (including in connection with any action, suit or proceeding brought by any Holder, the Borrower, any other Loan Party or any Lender Party) as a result of, or arising out of, or relating to the execution, delivery, performance, administration or enforcement of this Agreement or any other Loan Document, the use of proceeds of the Loans, or the violation of, noncompliance with or liability under, any Environmental Law applicable to the operations of any Loan Party, except to the extent any such Indemnified Liabilities result from the applicable Lender Party’s own gross negligence, willful misconduct, or material breach of any Loan Document, in each case as determined by a court of competent jurisdiction in a final, non-appealable determination. If and to the extent that the foregoing undertaking may be unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the payment and satisfaction of each of the

45

Indemnified Liabilities which is permissible under Applicable Law. All Obligations provided for in this Section 10.4 shall survive repayment of the Loans, cancellation of the Notes, any foreclosure under, or any modification, release or discharge of, any or all of the Collateral Documents and termination of this Agreement.

10.5.Marshaling; Payments Set Aside. Neither the Agent nor the Lender shall be under any obligation to marshal any assets in favor of the Borrower or any other Person or against or in payment of any or all of the Obligations. To the extent that the Borrower makes a payment or payments to the Agent or the Lender, or the Agent or the Lender enforces its Liens or exercises its rights of set-off, and such payment or payments or the proceeds of such enforcement or set-off or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Agent or the Lender in its discretion) to be repaid to a trustee, receiver or any other party in connection with any bankruptcy, insolvency or similar proceeding, or otherwise, then (a) to the extent of such recovery, the obligation hereunder or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred and (b) the Lender severally agrees to pay to the Agent upon demand its ratable share of the total amount so recovered from or repaid by the Agent to the extent paid to such Lender.

10.6.Nonliability of the Lender. The relationship between the Borrower on the one hand and the Lender and the Agent on the other hand shall be solely that of borrower and lender. Neither the Agent nor the Lender shall have any fiduciary responsibility to the Holders, the Borrower or any other Loan Party. Neither the Agent nor the Lender undertakes any responsibility to the Holders, the Borrower or any other Loan Party to review or inform (including payment of all outstanding principal), the Borrower or any other Loan Party of any matter in connection with any phase of the Borrower’s or any other Loan Party’s business or operations. Execution of this Agreement by the Borrower constitutes a full, complete and irrevocable release of any and all claims which the Borrower may have at law or in equity in respect of all prior discussions and understandings, oral or written, relating to the subject matter of this Agreement and the other Loan Documents. Neither the Borrower, the Agent nor the Lender shall have any liability with respect to, and the Borrower, Agent and Lender each hereby waives, releases and agrees not to sue for, any special, indirect, punitive or consequential damages or liabilities.

46

any court decree, subpoena or legal or administrative order or process; (d) as, on the advice of the Agent’s or such Lender’s counsel, is required by law; (e) in connection with the exercise of any right or remedy under the Loan Documents or in connection with any litigation to which the Agent or such Lender is a party; (f) to any nationally recognized rating agency or investor of the Lender that requires access to information about the Lender’s investment portfolio in connection with ratings issued or investment decisions with respect to such Lender; (g) that ceases to be confidential through no fault of the Agent or the Lender; or (h) to a Person that is an investor or prospective investor in the Agent or any of its Affiliates.

10.8.Captions. Captions used in this Agreement are for convenience only and shall not affect the construction of this Agreement.

10.9.Nature of Remedies. All Obligations of the Borrower and rights of the Agent and the Lender expressed herein or in any other Loan Document shall be in addition to and not in limitation of those provided by Applicable Law. No failure to exercise and no delay in exercising, on the part of the Agent or the Lender, any right, remedy, power or privilege hereunder, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

10.10.Counterparts. This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts and each such counterpart shall be deemed to be an original, but all such counterparts shall together constitute but one and the same Agreement.

Fair Value Disclosures [Abstract]

Fair Value Measurements

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 pay 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.

	September 30, 2013						December 31, 2012
	Level 1		Level 2		Total		Level 1		Level 2		Total
(In thousands)
Financial assets:
Money market funds	$	269,806	$	—	$	269,806	$	121,095	$	—	$	121,095
Certificates of deposit	—		1,682		1,682		—		26,128		26,128
Corporate securities	—		5,180		5,180		—		—		—
Corporate debt securities	—		—		—		—		13,572		13,572
Total	$	269,806	$	6,862	$	276,668	$	121,095	$	39,700	$	160,795
Financial liabilities:
Foreign currency hedge contracts	$	—	$	7,508	$	7,508	$	—	$	7,581	$	7,581

The fair value of the certificates of deposit is determined using quoted market prices for similar instruments and non-binding market prices that are corroborated by observable market data. At December 31, 2012, the certificates of deposit included a $20.0 million certificate of deposit that was restricted as it was purchased to collateralize the line of credit for Merus Labs; see Note 6.

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

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

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

There have been no transfers between levels during the three and nine months ended September 30, 2013, and December 31, 2012. The Company recognizes transfers between levels on the date of the event or change in circumstances that caused the transfer.

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

Total	$	318,081	$	457,122	$	—	$	309,952	$	410,487	$	—

As of September 30, 2013, the estimated fair value of our Avinger note receivable, as of September 30, 2013 and December 31, 2012, the estimated fair values of our Wellstat Diagnostics note receivable and AxoGen note receivable and derivative, and as of December 31, 2012, the estimated fair value of our Merus Labs note receivable, were determined using one or more discounted cash flow models, incorporating expected principal payments and the interest rate extended for notes with fixed interest rates and incorporating expected payments for notes with a variable rate of return.

On September 30, 2013, and December 31, 2012, the carrying value of the AxoGen note and derivative approximated its estimated fair value. We determined this note to be a Level 3 asset, as our valuation utilized significant unobservable inputs, including estimates of AxoGen's future revenues, expectations about settlement and required yield. To provide support for the estimated fair value measurement, we considered forward looking performance related to AxoGen and current measures associated with high yield indices, and reviewed the terms and yields of notes placed by specialty finance and venture firms both across industries and in a similar sector. Additionally, we reviewed market yield indices for changes since the issuance of the note. We observed no material events with AxoGen or in the market in which it participates since the placement. The carrying value and estimated fair value of the AxoGen note include the value of a change of control embedded derivative valued at $1.0 million and $0.6 million at September 30, 2013, and December 31, 2012, respectively. We utilized discounted cash flows and probability analysis to determine the fair value of the embedded derivative.

On September 30, 2013, and December 31, 2012, the carrying value of the note receivable from Wellstat Diagnostics approximates its fair value. We determined this note to be a Level 3 asset, as our valuation utilized significant unobservable inputs. Due to the breach of the credit agreement as of December 31, 2012, as discussed in Note 6, we considered the fair value of the underlying collateral when estimating fair value of the note. The note is collateralized by all assets and equity interest in Wellstat Diagnostics. The fair value of the collateral was determined by using a discounted cash flow analysis related to the underlying technology included in the collateral. The discounted cash flow was based upon expected income from sales of planned products over a 15-year period. The terminal value was estimated using selected market multiples based on sales and EBITDA. Our valuation of the collateral utilized significant unobservable inputs including a discount rate of 35%, terminal value EBITDA multiple of 17.5, terminal value sales multiple of 3.0 and future revenue and expenses related to commercialization of the borrower's technology.

On September 30, 2013, the carrying value of the Avinger note approximates its fair value. We determined this note to be a Level 3 asset, as our valuation utilized significant unobservable inputs, including a discount rate of 18.5%, estimates of Avinger's future revenues, expectations about settlement and required yield. To provide support for the fair value measurement, we considered forward looking performance related to Avinger, current measures associated with high yield and Standard & Poor's Leveraged Commentary & Data indices, and reviewed the terms and yields of notes placed by specialty finance and venture firms both across industries and in a similar sector.

The fair values of our convertible notes were determined using quoted market pricing or dealer quotes.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

1. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. GAAP for interim financial information. The financial statements include all adjustments (consisting only of normal recurring adjustments) that management of PDL 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, 2012, included in our Annual Report on Form 10-K filed with the SEC. The Condensed Consolidated Balance Sheet at December 31, 2012, has been derived from the audited Consolidated Financial Statements at that date.

Principles of Consolidation

The Condensed Consolidated Financial Statements include the accounts of PDL and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. Our condensed consolidated financial statements are prepared in accordance with GAAP and the rules and regulations of the SEC.

Notes Receivable and Other Long-Term Receivables

We account for our notes receivable at amortized cost, net of unamortized origination fees, if any.  Related fees and costs are recorded net of any 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 as follows:

		Three Months Ended September 30,				Nine Months Ended September 30,
Licensee	Product Name	2013		2012		2013		2012
Genentech	Avastin®	33	%	30	%	34	%	31	%
	Herceptin®	32	%	36	%	33	%	35	%
	Lucentis®	14	%	15	%	17	%	18	%
Biogen Idec1	Tysabri®	12	%	14	%	11	%	12	%

______________________

¹ In April 2013, Biogen Idec completed its purchase of Elan's interest in Tysabri. Prior to this our licensee for Tysabri was identified as Elan.

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

At the inception of each hedging relationship and on a quarterly basis, we assess hedge effectiveness. The fair value of the Euro 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 component of the hedge is recorded in stockholders’ equity (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 portion of our hedge contracts is reported in interests and other income, net in the period the ineffectiveness occurs.

Comprehensive Income

In the first quarter of 2012, we adopted FASB 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

In January 2013, we adopted the provisions of ASU 2013-01, issued by the FASB, which requires new asset and liability offsetting disclosures for derivatives, repurchase agreements and security lending transactions to the extent that they are: (1) offset in the financial statements or (2) subject to an enforceable master netting arrangement or similar agreement. We do not have any repurchase agreements and do not participate in securities lending transactions. Our derivative instruments are not offset in the financial statements and are not subject to any right of offset provisions with our counterparties. Accordingly, this amendment did not have a material impact on our Condensed Consolidated Financial Statements. Additional information about derivative instruments can be found in Note 5.

In February 2013, FASB amended ASC 220, “Comprehensive Income.” This amendment requires companies to report, in one place, information about reclassifications (by component) out of accumulated other comprehensive income (loss). In addition, this amendment requires companies to present the related line item effect of significant reclassifications on the statement where income is presented. We adopted the provisions of this amendment during the first quarter of 2013, which affects only the display of information and does not change existing recognition and measurement requirements in our Condensed Consolidated Financial Statements.

Cash Equivalents and Investments

4. Cash Equivalents and Investments

As of September 30, 2013, and December 31, 2012, we had invested our excess cash balances primarily in money market funds, certificates of deposit, corporate securities and corporate debt securities. Our securities are classified as available-for-sale and are carried at estimated fair value, with unrealized gains and losses reported in accumulated other comprehensive income (loss) in stockholders’ equity (deficit), net of estimated taxes. 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.

Net income per diluted share	$	0.36	$	0.32	$	1.31	$	1.08

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 by the Company.

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 February 2015 Notes, our Series 2012 Notes and our May 2015 Notes on a weighted average basis for the period that the notes were outstanding, including the effect of adding back interest expense and the underlying shares using the if-converted method. In the first quarter of 2012, $179.0 million aggregate principal of our February 2015 Notes was exchanged for our Series 2012 Notes, and in the third quarter of 2013, $1.0 million aggregate principal of our February 2015 Notes was exchanged for our Series 2012 Notes, and the February 2015 Notes were retired.

In May 2011, we issued our May 2015 Notes, and in January and February 2012, we issued our Series 2012 Notes. 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, shown in the table above, include the shares issuable in respect of such excess.

We excluded from our calculations of net income per diluted share 20.8 million and 19.2 million shares for our warrants for the three months ended September 30, 2013 and 2012, respectively, and 20.8 million and 19.2 million shares for the nine months ended September 30, 2013 and 2012, respectively, for warrants issued in 2011, because the exercise price of the warrants exceeded the VWAP 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, issued in 2011, will always be anti-dilutive and therefore 24.4 million and 22.6 million shares were excluded from our calculations of net income per diluted share for the three months ended September 30, 2013 and 2012, respectively, and 24.4 million and 22.6 million shares were excluded for the nine months ended September 30, 2013 and 2012, respectively, because they have no effect on diluted net income per share. For information related to the conversion rates on our convertible debt, see Note 9.

For the three months ended September 30, 2013, we excluded approximately 121,000 and 10,000 shares underlying outstanding stock options and restricted stock awards, respectively, and for the nine months ended September 30, 2013, we excluded approximately 133,000 and zero shares underlying outstanding stock options and restricted stock awards, respectively, calculated on a weighted average basis, from our net income per diluted share calculations because their effect was anti-dilutive.

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

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2013

Accounting Policies [Abstract]

Basis of Presentation, Policy

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. GAAP for interim financial information. The financial statements include all adjustments (consisting only of normal recurring adjustments) that management of PDL 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, 2012, included in our Annual Report on Form 10-K filed with the SEC. The Condensed Consolidated Balance Sheet at December 31, 2012, has been derived from the audited Consolidated Financial Statements at that date.

Principles of Consolidation, Policy

Principles of Consolidation

The Condensed Consolidated Financial Statements include the accounts of PDL and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. Our condensed consolidated financial statements are prepared in accordance with GAAP and the rules and regulations of the SEC.

Notes Receivable and Other Long-Term Receivables, Policy

Notes Receivable and Other Long-Term Receivables

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

Customer Concentration, Policy

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 as follows:

		Three Months Ended September 30,				Nine Months Ended September 30,
Licensee	Product Name	2013		2012		2013		2012
Genentech	Avastin®	33	%	30	%	34	%	31	%
	Herceptin®	32	%	36	%	33	%	35	%
	Lucentis®	14	%	15	%	17	%	18	%
Biogen Idec1	Tysabri®	12	%	14	%	11	%	12	%

Foreign Currency Hedging, Policy

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

At the inception of each hedging relationship and on a quarterly basis, we assess hedge effectiveness. The fair value of the Euro 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 component of the hedge is recorded in stockholders’ equity (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 portion of our hedge contracts is reported in interests and other income, net in the period the ineffectiveness occurs.

Comprehensive Income, Policy

Comprehensive Income

In the first quarter of 2012, we adopted FASB 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

New Accounting Pronouncements

In January 2013, we adopted the provisions of ASU 2013-01, issued by the FASB, which requires new asset and liability offsetting disclosures for derivatives, repurchase agreements and security lending transactions to the extent that they are: (1) offset in the financial statements or (2) subject to an enforceable master netting arrangement or similar agreement. We do not have any repurchase agreements and do not participate in securities lending transactions. Our derivative instruments are not offset in the financial statements and are not subject to any right of offset provisions with our counterparties. Accordingly, this amendment did not have a material impact on our Condensed Consolidated Financial Statements. Additional information about derivative instruments can be found in Note 5.

In February 2013, FASB amended ASC 220, “Comprehensive Income.” This amendment requires companies to report, in one place, information about reclassifications (by component) out of accumulated other comprehensive income (loss). In addition, this amendment requires companies to present the related line item effect of significant reclassifications on the statement where income is presented. We adopted the provisions of this amendment during the first quarter of 2013, which affects only the display of information and does not change existing recognition and measurement requirements in our Condensed Consolidated Financial Statements.

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

Wellstat Diagnostics Note Receivable and Credit Agreement

In March 2012, the Company executed a $7.5 milliontwo-year senior secured note receivable with the holders of the equity interests in Wellstat Diagnostics. In addition to bearing interest at 10% per annum, the note gave PDL certain rights to negotiate for certain future financing transactions. In August 2012, PDL and the borrowers amended the note receivable, providing a senior secured note receivable of $10.0 million, bearing interest at 12% per annum, to replace the original $7.5 million note. This $10.0 million note was repaid on November 2, 2012.

On November 2, 2012, the Company and Wellstat Diagnostics entered into a $40.0 million credit agreement pursuant to which the Company is to accrue quarterly interest payments at the rate of 5% per annum (payable in cash or in kind). In addition, PDL will receive quarterly royalty payments based on a low double digit royalty rate of Wellstat Diagnostics' net revenues, generated by the sale, distribution or other use of Wellstat Diagnostics' products, if any, commencing upon the commercialization of its products.

In January 2013, the Company was informed that, as of November 2012, Wellstat Diagnostics had used funds contrary to the terms of the credit agreement and breached Sections 2.1.2 and 7 of the credit agreement. PDL sent Wellstat Diagnostics a notice of default on January 22, 2013, and accelerated the amounts owed under the credit agreement. In connection with the notice of default, PDL exercised one of its available remedies and transferred approximately $8.1 million of available cash from a bank account of Wellstat Diagnostics to PDL and applied the funds to amounts due under the credit agreement. On February 28, 2013, the parties entered into a forbearance agreement whereby PDL agreed to refrain from exercising additional remedies for 120 days while Wellstat Diagnostics raised funds to capitalize the business and the parties attempted to negotiate a revised credit agreement. PDL agreed to provide up to $7.9 million to Wellstat Diagnostics to fund the business for the 120-day forbearance period under the terms of the forbearance agreement. Following the conclusion of the June 28 forbearance period, the Company agreed to forbear in its exercise of remedies for additional periods of time to allow the owners and affiliates of Wellstat Diagnostics to complete a pending financing transaction. During such forbearance period, the Company provided approximately $1.3 million to Wellstat Diagnostics to fund ongoing operations of the business. During the nine months endedSeptember 30, 2013, approximately $8.7 million was advanced pursuant to the forbearance agreement.

On August 15, 2013, the owners and affiliates of Wellstat Diagnostics completed a financing transaction to fulfill its obligations under the forbearance agreement. On August 15, 2013, the Company entered into an amended and restated credit agreement with Wellstat Diagnostics. The Company determined that the new agreement should be accounted for as a modification of the existing agreement.

Except as otherwise described here, the material terms of the amended credit agreement are substantially the same as those of the original credit agreement, including quarterly interest payments at the rate of 5% per annum (payable in cash or in kind). In addition, PDL will continue to receive quarterly royalty payments based on a low double digit royalty rate of Wellstat Diagnostics' net revenues. However, pursuant to the amended credit agreement: (i) the principal amount was reset to approximately $44.1 million which was comprised of approximately $33.7 million original loan principal and interest, $1.3 million term loan principal and interest and $9.1 million forbearance principal and interest; (ii) the specified internal rates of return increased; (iii) the default interest rate was increased; (iv) Wellstat Diagnostics' obligation to provide certain financial information increased in frequency to monthly; (v) internal financial controls were strengthened by requiring Wellstat Diagnostics to maintain an independent, third-party financial professional with control over fund disbursements; (vi) the Company waived the existing events of default; and (vii) the owners and affiliates of Wellstat Diagnostics are required to contribute additional capital to Wellstat Diagnostics upon the sale of an affiliate entity. The restated credit agreement continues to have an ultimate maturity date of December 31, 2021 (but may mature earlier upon certain specified events).

When the principal amount was reset it resulted in a $2.5 million reduction of the carrying value and was recorded as a financing cost as a component of interest and other income, net. The new carrying value is lower as a function of the variable nature of the internal rate of return to be realized by the Company based on when the note is repaid. The internal rate of return calculation, although increased, was reset when the credit agreement was amended and restated.

Wellstat Diagnostics may prepay the amended credit agreement at a price that, together with interest and royalty payments already made to the Company, would generate a specified internal rate of return to the Company. In the event of a change of control, bankruptcy or certain other customary events of defaults, or Wellstat Diagnostics' failure to achieve a specified annual revenue threshold in 2017, Wellstat Diagnostics will be required to prepay the credit agreement at a price that, together with interest and royalty payments already made to the Company, would generate a specified internal rate of return to the Company. The amended credit agreement is secured by a pledge of all of the assets of Wellstat Diagnostics, a pledge of all of Wellstat Diagnostics’ equity interests by the holders thereof, and a second lien on the assets of the affiliates of Wellstat Diagnostics.The Company believes the fair value of the collateral is not less than$76.6 million.

At September 30, 2013, and December 31, 2012, the carrying value of the note was included in non-current assets.

As of September 30, 2013, the Company determined that its interest in Wellstat Diagnostics represented a variable interest in a Variable Interest Entity since Wellstat Diagnostics' equity was not sufficient to finance its operations without amounts advanced to it under the Company's note and forbearance agreement. However, the Company does not have the power to unilaterally direct operational activities of Wellstat Diagnostics and is not the primary beneficiary of Wellstat Diagnostics; therefore, Wellstat Diagnostics is not subject to consolidation.

As of September 30, 2013, the carrying value of all amounts advanced to Wellstat Diagnostics was $45.3 million, which was recorded in notes receivable. As of September 30, 2013, the maximum loss exposure was $45.3 million.

Merus Labs Note Receivable and Credit Agreement

In July 2012, PDL loaned $35.0 million to Merus Labs in connection with its acquisition of a commercial-stage pharmaceutical product and related assets. In addition, PDL agreed to provide a $20.0 million letter of credit on behalf of Merus Labs for the seller of the assets to draw upon to satisfy the remaining $20.0 million purchase price obligation. The seller made this draw on the letter of credit in July 2013 and an additional loan to Merus Labs for $20.0 million was recorded for an aggregate of $55.0 million in total borrowings.

Outstanding borrowings under the July 2012 loan bore interest at the rate of 13.5% per annum and outstanding borrowings as a result of the draw on the letter of credit bore interest at the rate of 14.0% per annum. Merus Labs was required to make four periodic principal payments in respect of the July 2012 loan, with repayment of the remaining principal balance of all loans due on March 31, 2015. The borrowings were subject to mandatory prepayments upon certain asset dispositions or debt issuances as set forth in the credit agreement. Merus Labs made the first of these payments in December 2012 in the amount of $5.0 million, and made the second payment in June 2013 in the amount of $7.5 million. In September 2013, Merus Labs made two additional payments totaling $43.3 million, including the prepayment fee, in order to pay its remaining outstanding balance.

In September 2013, Merus Labs prepaid in full its obligations under the credit agreement , including accrued interest through the payment date and a prepayment fee of 1% of the aggregate principal amount outstanding at the time of repayment. There was no outstanding balance owed as of September 30, 2013.

AxoGen Note Receivable and Royalty Agreement

In October 2012, PDL entered into the Royalty Agreement with AxoGen pursuant to which the Company 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 years term and provides PDL with royalties of 9.95% based on AxoGen Net Revenues, subject to agreed-upon guaranteed quarterly minimum payments of approximately $1.3 to $2.3 million beginning in the fourth quarter of 2014, and the right to require AxoGen to repurchase the Royalty Agreement at the end of the fourth year. AxoGen has been granted certain rights to call the 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.

Under the Royalty Agreement, beginning on October 1, 2016, or in the event of the occurrence of a material adverse event or AxoGen's bankruptcy or material breach of the Royalty Agreement, the Company may require AxoGen to repurchase the royalty rights at a price that, together with payments already made by AxoGen, would generate a specified internal rate of return to the Company. The Company has concluded that the repurchase option is an embedded derivative which should be bifurcated and separately accounted for at fair value.

In the event of a change of control, AxoGen must repurchase the assigned interests from the Company for a repurchase price equal to an amount that, together with payments already made by AxoGen, would generate a 32.5% internal rate of return to the Company. The Company has concluded that the change of control provision is an embedded derivative that should be bifurcated and separately recorded at its estimated fair value. The estimated fair value of the change of control provision was approximately $1.0 million and $0.6 million as of September 30, 2013, and December 31, 2012, respectively. The estimated fair value of this embedded derivative is included in the carrying value of the AxoGen Note Receivable. The Company recognized approximately $0.0 million and $0.4 million related to the change in the estimated fair value of embedded derivative during the three and nine month periods ended September 30, 2013, respectively.

At any time after September 30, 2016, AxoGen, at its option, can repurchase the assigned interests under the Royalty Agreement for a price applicable in a change of control.

During the term of the Royalty Agreement, the Company is entitled to designate an individual to be a member of AxoGen's board of directors. The Company has exercised this right and on October 5, 2012, upon close of the transaction, the Company's President and Chief Executive Officer was elected to AxoGen's board of directors.

On August 14, 2013, PDL purchased 1,166,666 shares of AXGN at $3.00 per share, totaling $3.5 million. The shares are classified as available for sale and recorded as short term investments on the balance sheet. As of September 30, 2013, the shares were valued at $5.2 million, which results in an unrealized gain of $1.7 million and is recorded in other comprehensive income.

Avinger Note Receivable and Royalty Agreement

On April 18, 2013, PDL entered into a credit agreement with Avinger, under which we made available to Avinger up to $40.0 million to be used by Avinger in connection with the commercialization of its currently marketed lumivascular catheter devices and in the development of Avinger's lumivascular atherectomy device. Of the $40.0 million available to Avinger, we funded an initial $20.0 million, net of fees, at close of the transaction. Upon the attainment by Avinger of a certain revenue milestone to be accomplished no later than the end of the first half of 2014, we will fund them an additional amount between $10.0 million and $20.0 million (net of fees) at Avinger's election. Outstanding borrowings under the initial loan bear interest at a stated rate of 12% per annum, and any future outstanding borrowings as a result of an additional amount funded upon reaching the revenue milestone will bear interest at the rate of 14% per annum.

Avinger is required to make quarterly interest and principal payments. Principal repayment will commence on: (i) the eleventh interest payment date if the revenue milestone is not achieved or (ii) the thirteenth interest payment date if the revenue milestone is achieved. The principal amount outstanding at commencement of repayment, after taking into account any payment-in-kind, will be repaid in equal installments until final maturity of the loans. The loans will mature in April 2018.

In connection with entering into the credit agreement, the Company will receive a low, single-digit royalty on Avinger's net revenues through April 2018. Avinger may prepay the outstanding principal and accrued interest on the notes receivable at any time. If Avinger repays the notes receivable prior to April 2018, the royalty on Avinger's net revenues will be reduced by 50% and will be subject to certain minimum payments from the prepayment date through April 2018.

The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Avinger and any of its subsidiaries (other than controlled foreign corporations, if any). The credit agreement provides for a number of standard events of default, including payment, bankruptcy, covenant, representation and warranty and judgment defaults.

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

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. In August 2013, the Company entered into a separate privately negotiated exchange agreement under which it retired the final $1.0 million aggregate principal amount of the Company's outstanding February 2015 Notes. Pursuant to the exchange agreement, the holder of the February 2015 Notes received $1.0 million aggregate principal amount of the Company's Series 2012 Notes. Immediately following the exchange, no principal amount of the February 2015 Notes remained outstanding and $180.0 million principal amount of the Series 2012 Notes is outstanding.

The terms of the Series 2012 Notes are governed by the indenture dated as of January 5, 2012, 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.

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.

As of September 30, 2013, our Series 2012 Notes are convertible into 179.777 shares of the Company’s common stock per $1,000 of principal amount, or approximately $5.56 per common share, subject to further adjustment upon certain events including dividend payments. As of September 30, 2013, the remaining discount amortization period was 1.4 years.

Our common stock exceeded the conversion threshold price of $7.37 for at least 20 days during the 30 consecutive trading days ended June 30, 2013; accordingly, the Series 2012 Notes were convertible at the option of the holder during the quarter ended September 30, 2013. Our common stock price exceeded the conversion threshold price of $7.23 per common share for at least 20 days during the 30 consecutive trading days ended September 30, 2013; accordingly, the Series 2012 Notes are convertible at the option of the holder during the quarter ending December 31, 2013. The Series 2012 Notes have been classified as current as the notes will be due upon demand within one year of the quarter ended September 30, 2013. At September 30, 2013, the if-converted value of our Series 2012 Notes exceeded their principal amount by approximately $77.9 million.

May 2015 Notes

On May 16, 2011, we issued $155.3 million in aggregate principal amount, at par, of our May 2015 Notes in an underwritten public offering, for net proceeds of $149.7 million. Our May 2015 Notes are due May 1, 2015, and we pay interest at 3.75% on our May 2015 Notes semiannually in arrears on May 1 and November 1 of each year, beginning November 1, 2011. Proceeds from our May 2015 Notes, net of amounts used for purchased call option transactions and provided by the warrant transactions described below, were used to redeem our 2012 Notes. Upon the occurrence of a fundamental change, as defined in the indenture, holders have the option to require PDL to repurchase their May 2015 Notes at a purchase price equal to 100% of the principal, plus accrued interest.

Our May 2015 Notes are convertible under any of the following circumstances:

• During any fiscal quarter ending after the quarter ending June 30, 2011, if the last reported sale price of our 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 notes on the last day of such preceding fiscal quarter;

• During the five business-day period immediately after any five consecutive trading-day period, which we refer to as the measurement period, in which the trading price per $1,000 principal amount of notes for each trading day of that measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the notes for each such day;

• Upon the occurrence of specified corporate events as described further in the indenture; or

• At any time on or after November 1, 2014.

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 our May 2015 Notes between the fair value of the debt component and the fair value of the common stock conversion feature. Using an assumed borrowing rate of 7.5%, which represents the estimated market interest rate for a similar nonconvertible instrument available to us on the date of issuance, we recorded a total debt discount of $18.9 million, allocated $12.3 million to additional paid-in capital and allocated $6.6 million to deferred tax liability. The discount is being amortized to interest expense over the term of our May 2015 Notes and increases interest expense during the term of our May 2015 Notes from the 3.75% cash coupon interest rate to an effective interest rate of 7.5%. As of September 30, 2013, the remaining discount amortization period is 1.6 years.

The carrying value and unamortized discount of our May 2015 Notes were as follows:

As of September 30, 2013, our May 2015 Notes are convertible into 157.37 shares of the Company’s common stock per $1,000 of principal amount, or approximately $6.35 per common share, subject to further adjustment upon certain events including dividend payments.

Our common stock did not exceed the conversion threshold price of $8.42 for at least 20 days during the 30 consecutive trading days ended June 30, 2013; accordingly, the May 2015 Notes were not convertible at the option of the holder during the quarter ended September 30, 2013. Our common stock price did not exceed the conversion threshold price of $8.26 per common share for at least 20 days during the 30 consecutive trading days ended September 30, 2013; accordingly, the May 2015 Notes are not convertible at the option of the holder during the quarter ending December 31, 2013. At September 30, 2013, the if-converted value of our May 2015 exceeded their principal amount by approximately $39.5 million.

Purchased Call Options and Warrants

In connection with the issuance of our May 2015 Notes, we entered into purchased call option transactions with two hedge counterparties. We paid an aggregate amount of $20.8 million, plus legal fees, for the purchased call options with terms substantially similar to the embedded conversion options in our May 2015 Notes. The purchased call options cover, subject to anti-dilution and certain other customary adjustments substantially similar to those in our May 2015 Notes, approximately 24.0 million shares of our common stock. 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. The purchased call options expire on May 1, 2015, or the last day any of our May 2015 Notes remain outstanding.

In addition, we sold to the hedge counterparties warrants exercisable, on a cashless basis, for the sale of rights to receive up to 27.5 million shares of common stock underlying our May 2015 Notes. We received an aggregate amount of $10.9 million for the sale from the two counterparties. The warrant counterparties may exercise the warrants on their specified expiration dates that occur over a period of time ending on January 20, 2016. If the VWAP of our common stock, as defined in the warrants, exceeds the strike price of the warrants, we will deliver to the warrant counterparties shares equal to the spread between the VWAP on the date of exercise or expiration and the strike price. If the VWAP is less than the strike price, neither party is obligated to deliver anything to the other.

The purchased call option transactions and warrant sales effectively serve to reduce the potential dilution associated with conversion of our May 2015 Notes. The strike prices are approximately $6.35 and $7.48, subject to further adjustment upon certain events including dividend payments, for the purchased call options and warrants, respectively.

If the share price is above $6.35, but below $7.48, upon conversion of our May 2015 Notes, the purchased call options will offset the share dilution, because the Company will receive shares on exercise of the purchased call options equal to the shares that the Company must deliver to the note holders. If the share price is above $7.48, upon exercise of the warrants, the Company will deliver shares to the counterparties in an amount equal to the excess of the share price over $7.48. For example, a 10% increase in the share price above $7.48 would result in the issuance of 1.9 million incremental shares upon exercise of the warrants. As our share price continues to increase, additional dilution would occur.

While the purchased call options are expected to reduce the potential equity dilution upon conversion of our May 2015 Notes, prior to conversion or exercise, our May 2015 Notes and the warrants could have a dilutive effect on the Company’s earnings per share to the extent that the price of the Company’s common stock during a given measurement period exceeds the respective exercise prices of those instruments. As of September 30, 2013, and December 31, 2012, the market price condition for convertibility of our May 2015 Notes was not met and there were no related purchased call options or warrants exercised.

The purchased call options and warrants are considered indexed to PDL stock, require net-share settlement, and met all criteria for equity classification at inception and at September 30, 2013, and December 31, 2012. The purchased call options cost, including legal fees, of $20.8 million, less deferred taxes of $7.2 million, and the $10.9 million received for the warrants, was recorded as adjustments to additional paid-in capital. Subsequent changes in fair value will not be recognized as long as the purchased call options and warrants continue to meet the criteria for equity classification.

February 2015 Notes

On November 1, 2010, we completed an exchange of $92.0 million in aggregate principal of our 2012 Notes in separate, privately negotiated transactions with the note holders. In the exchange transactions, the note holders received $92.0 million in aggregate principal of our February 2015 Notes, and we recorded a net gain of $1.1 million. As part of the transaction, we placed an additional $88.0 million in aggregate principal of our February 2015 Notes. In January 2012, we completed an exchange transaction where we exchanged and subsequently retired approximately $169.0 million aggregate principal amount of our February 2015 Notes for approximately $169.0 million aggregate principal amount of new Series 2012 Notes, plus a cash payment of $5.00 for each $1,000 principal amount tendered for a total cash incentive payment of approximately $0.8 million. In February 2012, we entered into separate privately negotiated exchange agreements under which we retired an additional $10.0 million aggregate principal amount of our February 2015 Notes for $10.0 million aggregate principal amount of our Series 2012 Notes. In August 2013, the Company entered into a separate privately negotiated exchange agreement under which it retired the final $1.0 million aggregate principal amount of the Company's outstanding February 2015 Notes. Pursuant to the exchange agreement, the holder of the February 2015 Notes received $1.0 million aggregate principal amount of the Company's Series 2012 Notes. Immediately following the exchange, no principal amount of the February 2015 Notes remained outstanding. Our February 2015 Notes bore interest at 2.875% per annum.

Foreign Currency Hedging

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, 2013, and December 31, 2012, 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 flows under the de-designated contracts were probable to not occur, and recorded a gain of approximately $391,000 to interest and other income, net, 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.

The notional amounts, Euro exchange rates and fair values of our Euro forward contracts designated as cash flow hedges were as follows:

Euro Forward Contracts			September 30, 2013					December 31, 2012

Legal Proceedings

Genentech / Roche Matter

Communications with Genentech regarding European SPCs

In August 2010, we received a letter from Genentech, sent on behalf of Roche and Novartis, asserting that Avastin, Herceptin, Lucentis and Xolair do not infringe the SPCs granted to PDL by various countries in Europe for covering those 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 Avastin, Herceptin, Lucentis and Xolair. The SPCs covering Avastin, Herceptin, Lucentis and Xolair effectively extend our European patent protection for the '216B Patent generally until December 2014, except that the SPCs for Herceptin will generally expire in July 2014.

Genentech’s letter does not suggest that any of the Genentech Products do not infringe PDL’s U.S. patents to the extent that such Genentech Products are U.S.-based Sales. Genentech’s quarterly royalty payments received after receipt of the letter have 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 Avastin, Herceptin, Lucentis and Xolair that are both manufactured and sold outside of the United States. Royalties on sales of Avastin, Herceptin, Lucentis and Xolair that are ex-U.S.-based Manufacturing and Sales accounted for approximately 42% of our royalty revenues for the nine months endedSeptember 30, 2013.

We believe that the SPCs are enforceable, 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 and Arbitration with Genentech

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 Avastin, Herceptin, Lucentis and Xolair.

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.

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 parties have been engaged in discovery motion practice. On March 29, 2013, the court affirmed an order of the discovery commissioner requiring the production of certain documents in the possession of Roche and Genentech to PDL. Roche and Genentech have communicated to us that they have requested review of the court's order from the Nevada Supreme Court. The parties have agreed to a stay in the proceedings pending the decision of the Nevada Supreme Court regarding whether they will review the court's order. In the event that the Nevada Supreme Court agrees to consider Roche and Genentech's request and review the court's order, we expect a lengthy delay in the case schedule for a period that may extend for a number of months, and, while no trial date is currently scheduled with the District Court, the likelihood is that a trial date will be at some point between mid-2014 to mid-2015. The outcome of this litigation is uncertain and we may not be successful in our allegations.

On June 7, 2013, the Company filed a Notice of Arbitration against Genentech with the American Arbitration Association in Voorhees, New Jersey, alleging, inter alia, that Genentech underpaid royalties going back to at least 2007 and impeded PDL's attempts to have Genentech's books and records inspected to determine whether Genentech's past payments to PDL were accurately calculated.

In 2009, PDL retained KPMG to conduct an independent inspection and analysis of the books and records of Genentech and its sublicensees for the three year period covering January 1, 2007 to December 31, 2009, a right granted to PDL under PDL's Patent License Master Agreement and license agreements with Genentech. KPMG reported to PDL that, due to limitations on its inspection imposed by Genentech, it was unable to assess the completeness or accuracy of Genentech's reporting of royalties. KPMG concluded that, based on the limited information it was able to review, Genentech appears to have underpaid PDL in an amount that, if substantiated, PDL believes would be material. Genentech has informed PDL that it disagrees with KPMG's conclusions and that it believes that it has correctly calculated royalties due.

In the arbitration, PDL: (i) requests a declaration of the parties' rights and obligations with respect to reporting and payment of royalties under the license agreements; (ii) alleges that Genentech has breached the license agreements due to its obstruction of KPMG's inspection and underpayment of royalties; and (iii) alleges that Genentech breached the implied covenant of good faith and fair dealing by depriving PDL of the benefits of the license agreements through its obstruction of the inspection, which we further assert concealed the nature and extent of its underpayment.

On July 3, 2013, Genentech filed its Response and Counterclaim in which Genentech requests that the arbitrator (i) reject PDL's claims that Genentech breached the license agreements by underpaying royalties owed to PDL, obstructing KPMG's inspection, or violating the covenant of good faith and fair dealing; (ii) reject PDL's claim that Genentech owed any royalties to PDL on Herceptin, Avastin and Xolair manufactured and sold outside of the United States prior to December 27, 2009 on the ground that those products did not infringe the '216B patent prior to its expiration; (iii) offset any royalties underpaid during the audit period by the amount Genentech claims to have overpaid in royalties attributable to the sale of Herceptin, Avastin and Xolair manufactured and sold outside of the United States prior to December 27, 2009; and (iv) award damages to Genentech in the amount of $428,751, representing royalties Genentech overpaid during the audit period, as well as costs and reasonable attorney's fees. Genentech's counterclaim does not challenge whether Herceptin, Avastin and Xolair manufactured and sold outside of the United States after December 27, 2009, are Licensed Products (and subject to a royalty under PDL's SPCs issued to such products in Europe) as Genentech's ability to contest infringement of PDL's SPCs is the subject of pending litigation in Nevada.

The parties have mutually agreed to stay the arbitration proceedings and to extend the deadline for responses in the Nevada litigation to allow time for discussions to occur to determine if a settlement of certain issues is possible. The parties may not reach agreement regarding settlement terms and PDL expects that it will renew its litigation efforts if settlement is unsuccessful.

The outcome of this arbitration is uncertain, and PDL may not be successful in its allegations.

Other Legal Proceedings

In addition, from time to time, we are subject to various other legal proceedings and claims that arise in the ordinary course of business and that we do not expect to materially impact our financial statements.

Lease Guarantee

In connection with the Spin-Off, we entered into amendments to the leases for our former facilities in Redwood City, California, under which Facet was added as a co-tenant, 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 could 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, 2013, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately $92.7 million. If Facet were to default, we could 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.

We have recorded a liability of $10.7 million on our Condensed Consolidated Balance Sheets as of September 30, 2013, and December 31, 2012, related to this guarantee. In future periods, we may adjust this liability for any changes in the ultimate outcome of this matter that are both probable and estimable.

The transaction closed simultaneously with the execution of the royalty agreement.

Under the terms of the royalty agreement, the Company will receive all royalty and milestone payments due under license agreements between Depomed and its licensees until the Company has received payments equal to two times the cash payment made to Depomed, after which all net payments received will be shared evenly between the Company and Depomed.

Any future material domestic subsidiaries of the Company are required to guarantee the obligations of the Company under the credit agreement, except as otherwise provided by the credit agreement. The Company’s obligations under the Credit Agreement are secured by a lien on a substantial portion of its assets.

The credit agreement contains affirmative and negative covenants that the Company believes are usual and customary for a senior secured credit agreement. The credit agreement also requires compliance with certain financial covenants, including a maximum total leverage ratio and a debt service coverage ratio, in each case calculated as set forth in the credit agreement and compliance with which may be necessary to take certain corporate actions.

Income Taxes

13. Income Taxes

For the three and nine months ended September 30, 2013 and 2012, income tax expense was primarily derived by applying the federal statutory rate of 35% to operating income before income taxes.

During the second and third quarters of 2013, the Company released tax liabilities for the federal tax credits taken on the 2009 income tax return, in the amount of $5.7 million and $0.4 million, respectively. This resulted in a reduction to income tax expense for the second and third quarters of 2013. We expect to release additional tax liabilities in the third quarter of 2014 of approximately $7.0 million.

In general, our income tax returns are subject to examination by tax authorities for tax years 1996 forward. The California Franchise Tax Board is currently examining the Company’s 2008, 2009 and 2010 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, except as described above.
