Decision Made to Continue Pursuit of Income Generating Assets 2013 was a truly transformative year for PDL. With our Queen et al. patents expiring at the close of 2014, we set out, in 2012, to see if we could bring in additional assets that would generate income and enable us to extend our ability to pay dividends. We bolstered our team with strong, seasoned, well-connected individuals, and we began to evaluate the opportunities. By the end of 2012, we had closed three transactions and put $128 million to work. In 2013, I’m pleased to report that we deployed an additional $396 million in six transactions. Given this success, in early 2014, our board of directors made the decision to continue as an operating business after royalties related to the Queen et al. patents cease and to pursue our income generating asset acquisition strategy. PDL Capable of a Variety of Transaction Types and a Unique Financial Partner I believe that the combination of flexibility in transaction structures and having strong operational experience on our management team makes us a financial partner of choice to leading life science companies and other institutions who are seeking non-dilutive capital. By offering debt financing, royalty monetization or a hybrid of the two, we create solutions that fit the financial needs of our partners. We are actively working to continue to expand our portfolio of income generating assets and expect to achieve significant progress during the coming year. Annual Revenues Increased 18 Percent During 2013 During 2013, our total revenues increased 18 percent to $442.9 million from $374.5 million in 2012. The significant revenue growth was driven by increased sales our licensees’ products, Avastin®, Herceptin®, Lucentis®, Xolair®, Perjeta®, Kadcyla®, Tysabri®, and Actemra®, along with the addition of new royalty payments from our 2013 purchase of Depomed’s diabetes-related royalties. Early this year, we reached an agreement with Roche and Genentech resolving all outstanding legal disputes between us. We are pleased with the outcome and believe that our shareholders benefit from this settlement given that the royalty rate reflects an increase over historical rates, that there is now certainty around the period for which we will continue to receive royalties from Genentech, which is through the first quarter of 2016, and that PDL management can now devote its resources to building its portfolio of income generating assets. We will strive to build on the momentum we’ve achieved in recent months and look forward to sharing progress with you throughout the year. We value the support of our shareholders and look forward to returning value to you in the months and years ahead. Sincerely, John P.

All statements other than statements of historical facts are “forward-looking statements” for purposes of these provisions, including any projections of earnings, revenues or other financial items, any statements of the plans and objectives of management for future operations, including any statements concerning new licensing, any statements regarding future economic conditions or performance, and any statement of assumptions underlying any of the foregoing. In some cases, forward-looking statements can be identified by the use of terminology such as “may,” “will,” “intends,” “plans,” “believes,” “anticipates,” “expects,” “estimates,” “predicts,” “potential,” “continue” or “opportunity,” or the negative thereof or other comparable terminology. Although we believe that the expectations presented in the forward-looking statements contained herein are reasonable at the time of filing, there can be no assurance that such expectations or any of the forward-looking statements will prove to be correct, and actual results could differ materially from those projected or assumed in the forward-looking statements. Our future financial condition and results of operations, as well as any forward-looking statements, are subject to inherent risks and uncertainties, including but not limited to the risk factors set forth below, and for the reasons described elsewhere in this Annual Report. All forward-looking statements and reasons why results may differ included in this Annual Report are made as of the date hereof, and we assume no obligation to update these forward-looking statements or reasons why actual results might differ. We own or have rights to certain trademarks, trade names, copyrights and other intellectual property used in our business, including PDL BioPharma and the PDL logo, each of which is considered a registered trademark. All other company names, product names, trade names and trademarks included in this Annual Report are trademarks, registered trademarks or trade names of their respective owners. ITEM 1. BUSINESS 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, acquiring 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 continues to pursue this strategic initiative for which it has already invested approximately $500 million to date. 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. Financial information about our operations, including our revenues and net income for the years ended December 31, 2013, 2012 and 2011, and our total assets as of December 31, 2013 and 2012, is included in our consolidated financial statements and accompanying notes in Item 8, “Financial Statements and Supplementary Data.” 5 2014 Dividends We currently utilize dividends to increase return for our stockholders. On January 29, 2014, our board of directors declared that the regular quarterly dividends to be paid to our stockholders in 2014 will be $0.15 per share of common stock, payable on March 12, June 12, September 12 and December 12 of 2014 to stockholders of record on March 5, June 5, September 5 and December 5 of 2014, the record dates for each of the dividend payments, respectively. At the beginning of each fiscal year, our board of directors sets the Company’s total annual dividend payments for the 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 the dividend. 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. 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 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. Before August 15, 2013, we were entitled received a tiered royalty from one of our licensees, Genentech, based upon certain of their net sales of covered antibodies. After August 15, 2013, all of the royalties received from Genentech are based solely upon a flat-rate. 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. Our total revenues from U.S. based licensees under our Queen et al. patents were $154.2 million, $133.8 million and $137.3 million for the years ended December 31, 2013, 2012 and 2011, respectively. Our total revenues from foreign based licensees were $277.5 million, $240.7 million and $224.7 million for the years ended December 31, 2013, 2012 and 2011, respectively. 6 Licensing Agreements for Marketed Products In the year ended December 31, 2013, we received royalties on Queen et al. patents 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 Genentech................................................................................... Avastin® Product Names 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 years ended December 31, 2013, 2012 and 2011, we received royalty revenues under our license agreements of approximately $441.4 million, $374.5 million and $351.6 million, respectively. On February 22, 2013, Genentech/Roche 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. On November 20, 2013, Genentech/Roche announced EU approval for the treatment of adults with HER2-positive, inoperable locally advanced or metastatic breast cancer who previously received Herceptin and a taxane, separately or in combination. 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. On November 1, 2013, Genentech/Roche announced that Gazyva became the first therapy approved through the FDA’s breakthrough therapy designation, indicated in combination with chlorambucil to treat previously untreated chronic lymphocytic leukemia (CLL). PDL will begin receiving royalties in the first quarter of 2014 for the sales that occurred in the fourth quarter of 2013. 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. On January 31, 2014, we entered into a settlement agreement with Genentech and Roche which resolves all outstanding legal disputes between the parties, including our Nevada litigation with Genentech relating to an August 2010 facsimile sent by Genentech on behalf of Roche and Novartis asserting its products do not infringe on PDL’s SPC’s, and our arbitration proceedings with Genentech related to the audit of royalties on sales. Under the terms of the Settlement Agreement, effective retroactively to August 15, 2013, Genentech will pay a fixed royalty rate of 2.125 percent on worldwide sales of all its licensed products, as compared to the previous tiered royalty rate in the U.S and the fixed rate on all ex-U.S. based manufactured and sold licensed products. Pursuant to the agreement, Genentech and Roche confirmed that Avastin, Herceptin, Lucentis, Xolair and Perjeta are licensed products as defined in the relevant license agreements between the parties, and further agreed that Kadcyla and Gazyva are licensed products. Genentech will pay these royalties on all worldwide sales of Avastin, Herceptin, Xolair, Perjeta and Kadcyla occurring on or before December 31, 2015. With respect to Lucentis, Genentech will owe no royalties on U.S. sales occurring after June 30, 2013, and will pay a royalty of 2.125 percent on 7 all ex-U.S. sales occurring on or before December 28, 2014. The royalty term for Gazyva remains unchanged from the existing license agreement pertaining thereto. The Settlement Agreement precludes Genentech and Roche from challenging the validity of PDL’s patents, including its SPCs in Europe, from contesting their obligation to pay royalties, from contesting patent coverage for Avastin, Herceptin, Lucentis, Xolair, Perjeta, Kadcyla and Gazyva and from assisting or encouraging any third party in challenging PDL’s patents and SPCs. The Settlement Agreement further outlines the conduct of any audits initiated by PDL of the books and records of Genentech in an effort to ensure a full and fair audit procedure. Finally, the Settlement Agreement clarifies that the sales amounts from which the royalties are calculated does not include certain taxes and discounts. The Settlement Agreement provides greater certainty for each of the parties in terms of the royalty rate payable under the agreement and the period over which they will be payable. PDL expects to recognize royalty revenue on the licensed products until the first quarter of 2016. Additionally, the settlement terms provide for a better definition of revenues and audit inspection procedures related to the arbitration dispute filed by PDL. Based upon the flat royalty rate of 2.125 percent being retroactive to August 15, 2013, we expect to receive a one-time payment of net royalties due under the Settlement Agreement, which will be recognized as royalty revenue in the first quarter of 2014. Until the August 15, 2013, effective date of the above Settlement Agreement, our license agreement with Genentech entitled 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. Our master patent license agreement with Genentech provided for a tiered royalty structure under which the royalty rate Genentech paid 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 decreased 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. Net sales up to $1.5 billion...................................................................................................................................... Net sales between $1.5 billion and up to $2.5 billion ............................................................................................. Net sales between $2.5 billion and up to $4.0 billion ............................................................................................. Net sales exceeding $4.0 billion ............................................................................................................................. Genentech Products Made and Sold ex-U.S. Net sales .................................................................................................................................................................. Royalty Rate 3.0% 2.5% 2.0% 1.0% 3.0% As a result of the tiered royalty structure, Genentech’s average annual royalty rate for a given year declined as Genentech’s U.S.- based Sales increased during that year. Because we receive royalties one quarter in arrears, the average royalty rates for the payments we received from Genentech for U.S.-based Sales in the second calendar quarter for Genentech’s sales from the first calendar quarter were higher than the average royalty rates for following quarters. The average royalty rates for payments we received from Genentech were 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 bore royalties at the 1% royalty rate. In 2013, the blended rate for the full year of royalties from Genentech products was approximately 1.9%. 8 With respect to ex-U.S.-based Manufacturing and Sales, before August 15, 2013, the royalty rate that we received from Genentech was 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 fluctuated. 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: Avastin Herceptin Kadcyla Lucentis Perjeta Xolair Ex-U.S.-based sales........................................................................

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 years ended December 31, 2013, 2012 and 2011, 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. 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 year ended December 31, 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. On 9 November 20, 2013, Genentech/Roche announced EU approval for the treatment of adults with HER2-positive, inoperable locally advanced or metastatic breast cancer who previously received Herceptin and a taxane, separately or in combination. 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. On November 1, 2013, Genentech/Roche announced that Gazyva became the first therapy approved through the FDA’s breakthrough therapy designation, indicated in combination with chlorambucil to treat previously untreated chronic lymphocytic leukemia (CLL). PDL will begin receiving royalties in the first quarter of 2014 for the sales that occurred in the fourth quarter of 2013. 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 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. in patients with multiple sclerosis. 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. Depomed On October 18, 2013, we entered into a royalty purchase and sale agreement with Depomed, Inc. and its subsidiary, whereby we acquired the rights to receive royalties and milestones payable on sales of Type 2 diabetes products licensed by Depomed in exchange for a $240.5 million cash payment. As the licensor of certain patents, Depomed retains various rights, including the contractual right to audit its licensees and to ensure those licensees are complying with the terms of the underlying license agreement. Depomed retains full responsibility to protect and maintain the intellectual property rights underlying the licenses. In respect of the royalty stream relating to the Glumetza diabetes medication that we acquired from Depomed, which is the royalty right producing the highest revenues from the Depomed acquired royalties, U.S. patent protection for this product is expected to begin to expire in September 2016, and under settlement agreements to which Depomed is a party, certain manufacturers of generic products will be permitted to enter the market starting in February and August 2016. 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 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. 10 Protection of our Intellectual Property Our intellectual property, namely our Queen et al. patents and related license agreements, are integral to our business and generate nearly all of our revenues. Protection of our intellectual property is key to our success. Genentech / Roche Matter Settlement Agreement 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. On January 31, 2014, we entered into a settlement agreement with Genentech and Roche which resolves all outstanding legal disputes between the parties, including our Nevada litigation with Genentech relating to an August 2010 facsimile sent by Genentech on behalf of Roche and Novartis asserting its products do not infringe on PDL’s SPC’s, and our arbitration proceedings with Genentech related to the audit of royalties on sales. Under the terms of the Settlement Agreement, effective retroactively to August 15, 2013, Genentech will pay a fixed royalty rate of 2.125 percent on worldwide sales of all its licensed products, as compared to the previous tiered royalty rate in the U.S and the fixed rate on all ex-U.S. based manufactured and sold licensed products. Pursuant to the Settlement Agreement, Genentech and Roche confirmed that Avastin, Herceptin, Lucentis, Xolair and Perjeta are licensed products as defined in the relevant license agreements between the parties, and further agreed that Kadcyla and Gazyva are licensed products. Genentech will pay these royalties on all worldwide sales of Avastin, Herceptin, Xolair, Perjeta and Kadcyla occurring on or before December 31, 2015. With respect to Lucentis, Genentech will owe no royalties on U.S. sales occurring after June 30, 2013, and will pay a royalty of 2.125 percent on all ex-U.S. sales occurring on or before December 28, 2014. The royalty term for Gazyva remains unchanged from the existing license agreement pertaining thereto. The Settlement Agreement precludes Genentech and Roche from challenging the validity of PDL’s patents, including its SPCs in Europe, from contesting their obligation to pay royalties, from contesting patent coverage for Avastin, Herceptin, Lucentis, Xolair, Perjeta, Kadcyla and Gazyva and from assisting or encouraging any third party in challenging PDL’s patents and SPCs. The Settlement Agreement further outlines the conduct of any audits initiated by PDL of the books and records of Genentech in an effort to ensure a full and fair audit procedure. Finally, the Settlement Agreement clarifies that the sales amounts from which the royalties are calculated does not include certain taxes and discounts. The Settlement Agreement provides greater certainty for each of the parties in terms of the royalty rate payable under the agreement and the period over which they will be payable. PDL expects to recognize royalty revenue on the licensed products until the first quarter of 2016. Additionally, the settlement terms provide for a better definition of revenues and audit inspection procedures related to the arbitration dispute filed by PDL. Income Generating Asset Acquisitions The last of PDL’s Queen et al. patents expire in December 2014, with the obligation to pay royalties under the majority of our various license agreements expiring the first quarter of 2016. Consequently, we are acquiring income generating assets if such assets can be acquired on terms that allow us to increase the return to our stockholders. We primarily focus our income generating asset acquisition strategy on commercial stage therapies and devices having strong economic fundamentals and intellectual property protection. Notes and Other Long-term Receivables Wellstat Diagnostics Note Receivable and Credit Agreement In March 2012, the Company executed a $7.5 million two-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. 11 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 year ended December 31, 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 receive quarterly royalty payments based on a low double digit royalty rate of Wellstat Diagnostics' net revenues upon successful commercialization. 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, if any, of an affiliated 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 of the note receivable which 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 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. 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. 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. 12 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 December 31, 2013. AxoGen 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 (assigned interests). 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 $2.5 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 assigned interests 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 with a third party. 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 assigned interests at a price that, together with payments already made by AxoGen, would generate a specified internal rate of return to the Company. 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. 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. 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. 13 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. 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. 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). Within 9 months after the occurrence of the tranche two milestone, Durata may request up to a single additional $30 million borrowing. Until the occurrence of the tranche two milestone, outstanding borrowings under tranche one bear interest at the rate of 14.0% per annum, payable quarterly in arrears. Upon occurrence of the tranche two milestone, the interest rate of the loans will decrease to 12.75%. Principal repayment will commence on the fifth interest payment date, March 31, 2015. The principal amount outstanding will be repaid quarterly over the remainder of the loans in an increasing percentage of the principal outstanding at commencement of repayment. The loans will mature on October 31, 2018. Durata may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans. The Company is entitled to receive a fee in addition to the prepayment penalty in the event that Durata undergoes a change in control. The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Durata. Direct Flow Medical Credit Agreement 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 (tranche one), 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 tranche two milestone), the Company will loan to Direct Flow Medical an additional $15.0 million, net of fees.

A portion of the amount available under the agreement in an aggregate principal amount equal to $50 million, net of fees, was funded at the close of the transaction. In the event that certain specified sales and other milestones occur before December 31, 2014, PDL will fund Paradigm between an additional $6.25 million and $12.5 million, at Paradigm’s discretion. In the event that additional specified sales and other milestones occur before June 30, 2015, PDL will fund up to an additional $12.5 million also at Paradigm’s discretion. Borrowings under the credit agreement bear interest at the rate of 13.0% per annum, payable quarterly in arrears.

Paradigm may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans. The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Paradigm and its domestic subsidiaries and, initially, certain assets of Paradigm’s German subsidiaries. Intangible Assets 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. The royalty agreement terminates on the third anniversary following the date upon which the later of the following occurs: (a) October 25, 2021, or (b) at such time as no royalty payments remain payable under any license agreement and each of the license agreements has expired by its terms. Convertible Notes Series 2012 Notes We have actively worked to restructure the Company’s capital and reduce the potential dilution associated with our convertible notes. As part of those efforts, in January 2012, we exchanged and subsequently retired $169.0 million aggregate principal amount of our February 2015 Notes for an identical principal amount of our 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 exchanged and subsequently 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 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 is due in cash, and to the extent that the conversion value exceeds the principal amount, the difference is due in shares of our common stock. The effect of issuing $179.0 million aggregate principal of our Series 2012 Notes with the net share settle feature in exchange for our February 2015 Notes was the reduction of 27.8 million shares of potential dilution to our stockholders at the time of the exchange. On February 5 and 6, 2014, the Company entered into separate, privately negotiated exchange and purchase agreements under which it retired $131.7 million in aggregate principal of the Company’s outstanding Series 2012 Notes. The exchange agreements 15 provided for the issuance, by the Company, of shares of common stock and a cash payment for the Series 2012 Notes being exchanged, and the purchase agreement provided for a cash payment for the Series 2012 Notes being repurchased. The Company issued a total of 20.3 million shares of its common stock and paid an aggregate cash payment of $34.2 million pursuant to the exchange and repurchase agreements. May 2015 Notes On May 16, 2011, the Company 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. February 2018 Notes On February 6, 2014, the Company agreed to sell $260.87 million aggregate principal amount of its 4.00% Convertible Senior Notes due February 1, 2018, in an underwritten public offering. The conversion rate of the February 2018 Notes will initially be 109.1048 shares of common stock per $1,000 principal amount of the February 2018 Notes equivalent to an initial conversion price of approximately $9.17 per share of common stock. The conversion rate, subject to increase under certain circumstances, will not be increased in respect of regular quarterly cash dividends paid by us that do not exceed $0.15 per share. On February 12, 2014, the Company issued $300 million aggregate principal amount of February 2018 Notes, which included $39.13 million aggregate principal amount of February 2018 Notes issued pursuant to the exercise of the underwriters’ overallotment option to purchase additional 2018 Notes. In connection with the offering of the February 2018 Notes, PDL entered into privately negotiated convertible note hedge transactions with affiliates of RBC Capital Markets and Well Fargo Securities (“hedge counterparties”) and privately negotiated warrant transactions with the hedge counterparties relating to the same number of shares of PDL’s common stock. Effect of December 12, 2013, Dividend Payment on Conversion Rates for the Convertible Notes In connection with the December 12, 2013, dividend payment, the conversion rates for our convertible notes adjusted as follows: Convertible Notes Series 2012 Notes ............................... May 2015 Notes.................................. Term Loan Conversion Rate per $1,000 Principal Amount Approximate Conversion Price Per Common Share 182.598 159.9165 $ $ 5.48 6.25 Effective Date December 3, 2013 December 3, 2013 On October 28, 2013, PDL entered into the Term loan for $75 million, with a term of one year. 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. As of December 31, 2013, the interest rate was 2.24%. Interest and principal payments associated with the Term Loan 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 Term Loan, except as otherwise provided. The Company’s obligations under the Term Loan are secured by a lien on a substantial portion of its assets. The Term Loan contains affirmative and negative covenants that the Company believes are usual and customary for a senior secured credit agreement. The Term loan 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 Term Loan and compliance with which may be necessary to take certain corporate actions. 16 The Term Loan contains events of default that the Company believes are usual and customary for a senior secured credit agreement. Major Customers Our revenues consist almost entirely of royalties. We also receive periodic milestone payments from licensees of our Queen et al. patents and may continue to receive payments if the licensed products in development achieve certain development milestones. In addition, we will 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. In 2013, 2012 and 2011, Genentech accounted for 83%, 85%, and 86% of our revenues, respectively, and Biogen Idec (formerly Elan) accounted for 11%, 13% and 12% of our revenues, respectively. Employees As of December 31, 2013, we had less than ten full-time employees managing our intellectual property, our asset acquisitions and other corporate activities as well as providing for certain essential reporting and management functions of a public company. None of our employees are covered by a collective bargaining agreement.

RISK FACTORS You should carefully consider and evaluate all of the information included and incorporated by reference in this Annual Report, including the risk factors listed below. Any of these risks, 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. Keep these risk factors in mind when you read forward-looking statements contained in this Annual Report and the documents incorporated by reference in this Annual Report. These statements relate to our expectations about future events and time periods. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “intends,” “plans,” “believes,” “anticipates,” “expects,” “estimates,” “predicts,” “potential,” “continue” or “opportunity,” the negative of these words or words of similar import. Similarly, statements that describe our reserves and our future plans, strategies, intentions, expectations, objectives, goals or prospects are also forward-looking statements. Forward-looking statements involve risks and uncertainties, and future events and circumstances could differ significantly from those anticipated in the forward-looking statements. We must protect our patent and other intellectual property rights to succeed. Our success is dependent in significant part on our ability to protect the scope, validity and enforceability of our intellectual property, including our patents, SPCs and license agreements. The scope, validity, enforceability and effective term of patents and SPCs can be highly uncertain and often involve complex legal and factual questions and proceedings. In addition, the legal principles applicable to patents in any given jurisdiction may be altered through changing court precedent and legislative action, and such changes may affect the scope, strength and enforceability of our patent rights or the nature of proceedings which may be brought by us or a third party related to our patent rights. A finding in a proceeding related to our patent rights which narrows the scope or which affects the validity or enforceability of some or all of our patent rights could have a material impact on our ability to continue to collect royalty payments from our licensees or execute new license agreements. Any of these proceedings could further result in either loss of a patent or loss or reduction in the scope of one or more of the claims of the patent or claims underlying an SPC. These proceedings could be expensive, last several years and result in a significant reduction in the scope or invalidation of our patents. Any limitation in claim scope could reduce our ability to collect royalties or commence enforcement proceedings based on these patents. Moreover, the scope of a patent in one country does not assure similar scope of a patent with similar claims in another country. Also, claim interpretation and infringement laws vary among countries. Additionally, we depend on our license agreements to enforce royalty obligations against our licensees. Any limitations in our ability to enforce, such as limits on the scope of and/or an adverse interpretation of, the various licensee obligations in our licenses and related agreements could reduce our ability to collect royalties based on our license agreements. As a result of these factors, we are unable to predict the extent of our intellectual property protection in any country. For further information, see “Item 3—Legal Proceedings.” Failure to acquire additional sources of revenue, including royalty revenue, after expiration of our Queen et al. patents may cause us to have insufficient revenues to continue operations. Substantially all of our revenues consist of royalties from licensees of our Queen et al. patents, which expire in December 2014. Unless we are able to acquire sufficient alternative income-generating assets, such as royalty rights on commercially reasonable terms, we will no longer receive patent-related royalties or other revenues once our Queen et al. licensees have sold all their inventory of licensed product on which they are contractually bound to pay us a royalty. If we are unsuccessful in acquiring sufficient new sources of income, we will likely liquidate our business. Our common stock may lose value, our common stock could be delisted from NASDAQ and our business may be liquidated due to several factors, including the expiration of our Queen et al. patents, the failure to acquire additional sources of revenue, the payment of dividends or distributions to our stockholders and failure to meet analyst expectations. Our revenues consist almost entirely of royalties from licensees of our Queen et al. patents, which finally expire in December of 2014. The continued payment of dividends or distributions to our stockholders without other revenue sources and the approaching patent expiration will likely reduce the price of our common stock. If the price of our common stock were to fall below NASDAQ listing standards, our common stock may be delisted. If our common stock were delisted, market liquidity for our common stock could be severely affected and our stockholders’ ability to sell securities in the secondary market could be limited. Delisting from NASDAQ would negatively affect the value of our common stock. Delisting could also have other negative results, including, but not limited to, the potential loss of confidence by employees, the loss of institutional investor interest and fewer business development opportunities. 18 Our revenues in Europe depend on the validity and enforceability of our SPCs and an adverse judgment would severely reduce our future revenues. Our ‘216B Patent in Europe was granted in 1996 by the European Patent Office. The ‘216B Patent expired on December 28, 2009. To extend the period of enforceability of the ‘216B Patent against specific products which received marketing approval in Europe as of the expiration date of the ‘216B Patent, we applied for SPCs in various European national patent offices to cover the SPC Products to the extent these products are made and/or sold in Europe. These SPCs generally expire in 2014. While our SPCs extend the period of enforceability of our ‘216B Patent against the SPC Products, their enforcement will be subject to varying, complex and evolving national requirements and standards relevant to enforcement of patent claims pursuant to SPCs. In the event that our SPCs are challenged in the national patent offices or national courts of the various countries in Europe in which we own granted SPCs, such a challenge could be directed against the validity of the SPC, the validity of the underlying patent claims, whether the product named in the SPC is protected by the underlying patent in accordance with controlling European law and/or whether the SPC was properly granted pursuant to controlling European law. Such a proceeding would involve complex legal and factual questions. In addition, the European Court of Justice has the authority to interpret the SPC regulation and could do so in a manner that materially impacts the enforceability of our SPCs against the SPC Products. As a result of these factors, we are unable to predict the extent of protection afforded by our SPCs. Based on information provided to us in the quarterly royalty statements from our licensees, the royalties we collect on sales of the SPC Products approximated 43%, 38% and 33% of our royalty revenues for the years ended December 31, 2013, 2012 and 2011. Our inability to collect those royalties would have a material negative impact on our cash flow, our ability to pay dividends in the future and our ability to service our debt obligations. An adverse decision could also encourage challenges to our related Queen et al. patents in other jurisdictions including the United States. For further information, see “Item 3—Legal Proceedings.” 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 difficulty 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. We derive a significant portion of our royalty revenues from Genentech and our future success depends on continued market acceptance of their products and approval of their licensed products that are in development, as well as continued performance by Genentech of its obligations under its agreements with us. Our revenues consist almost entirely of royalties from licensees of our Queen et al. patents of which the Genentech Products accounted for 83%, 85% and 86% of our revenues for the years ended December 31, 2013, 2012 and 2011, respectively. Our future success, at least prior to the expiration of the Queen et al. patents, depends upon the continued market acceptance of the Genentech Products and upon the ability of Genentech to develop, introduce and deliver products that achieve and sustain market acceptance. We have no control over the sales efforts of Genentech and our other licensees, and our licensees might not be successful. Reductions in the sales volume or average selling price of Genentech Products could have a material adverse effect on our business. In addition, our business and results of operations also depend on Genentech continuing to perform its obligations under its license agreements with us. 19 Our licensees, borrowers and royalty-agreement counterparties may be unable to maintain regulatory approvals for currently licensed products, or to obtain regulatory approvals for new products, and they may voluntarily remove currently licensed products from marketing and commercial distribution. Any of such events, whether due to safety issues or other factors, could reduce our revenues. Our licensees, borrowers and royalty-agreement counterparties are subject to stringent regulation with respect to product safety and efficacy by various international, federal, state and local authorities. Of particular significance are the FDA requirements covering research and development, testing, manufacturing, quality control, labeling and promotion of drugs for human use in the United States. As a result of these requirements, the length of time, the level of expenditures and the laboratory and clinical information required for approval of a biologic license application or new drug application are substantial and can require a number of years. In addition, even if our licensees’, borrowers' and royalty-agreement counterparties' products receive regulatory approval, they remain subject to ongoing FDA and other international regulations including, but not limited to, obligations to conduct additional clinical trials or other testing, changes to the product label, new or revised regulatory requirements for manufacturing practices, written advisements to physicians and/or a product recall or withdrawal. Our licensees, borrowers and royalty-agreement counterparties may not maintain necessary regulatory approvals for their existing licensed products or our licensees may not obtain necessary regulatory approvals on a timely basis, if at all, for any of the licensed products our licensees are developing or manufacturing. The occurrence of adverse events reported by any licensee, borrower or royalty-agreement counterparty may result in the revocation of regulatory approvals or decreased sales of the applicable product due to a change in physicians’ willingness to prescribe, or patients’ willingness to use the applicable product. Our licensees, borrowers and royalty- agreement counterparties could also choose to voluntarily remove their licensed products from marketing and commercial distribution. In any of these cases, our revenues could be materially and adversely affected. For example, in November 2011, the FDA removed the indication for breast cancer from Avastin’s label. In 2005, Tysabri, was temporarily suspended and then returned to the market. In such cases, our revenues could be materially and adversely affected. In addition, the current regulatory framework could change, or additional regulations could arise at any stage during our licensees’ product development or marketing which may affect our licensees’ ability to obtain or maintain approval of their licensed products. Delays in our licensees receiving regulatory approval for licensed products or their failure to maintain existing regulatory approvals could have a material adverse effect on our business. Our licensees, borrowers and royalty-agreement counterparties face competition. Our licensees, borrowers and royalty-agreement counterparties face competition from other pharmaceutical, biotechnology, device and diagnostic companies. The introduction of new competitive products may result in lost market share for our licensees, borrowers and royalty-agreement counterparties, reduced use of their products, lower prices and/or reduced product sales, any of which could reduce our royalty revenues, or the revenues on which we rely to produce the returns on our acquisitions, and have a material adverse effect on our results of operations. Our current and future acquisitions of other material income generating asset transactions may not produce anticipated revenues, and if such transactions are secured by collateral, we may be, or may become, undersecured by the collateral or such collateral may lose value and we will not be able recuperate our capital expenditures in the acquisition. We are engaged in a continual review of opportunities to acquire income generating assets, whether royalty based or otherwise, or to acquire companies that hold royalty assets. We currently, and generally at any time, have acquisition opportunities in various stages of active review, including, for example, our engagement of consultants and advisors to analyze particular opportunities, technical, financial and other confidential information, submission of indications of interest and involvement as a bidder in competitive auctions. Many potential acquisition targets do not meet our criteria, and for those that do, we may face significant competition for these acquisitions from other royalty buyers and enterprises. Competition for future asset acquisition opportunities in our markets could increase the price we pay for such assets and could reduce the number of potential acquisition targets. The success of our income generating asset acquisitions is based on our ability to make accurate assumptions regarding the valuation, timing and amount of payments. The failure of any of these acquisitions to produce anticipated revenues may materially and adversely affect our financial condition and results of operations. Some of these income generating acquisitions expose us to credit risk in the event of default by the counterparty. To mitigate this risk, on occasion, we may obtain a security interest as collateral in the assets of such counterparty. Our credit risk in respect of such counterparty may be exacerbated when the collateral held by us cannot be realized upon or is liquidated at prices not sufficient to recover the full amount we are due pursuant to the terms of the particular income generating assets. This could occur in circumstances where the original collateral was not sufficient to cover a complete loss (e.g., our interests were only partially secured) or may result from the deterioration in value of the collateral, so that, in either such case, we are unable to recuperate our 20 full capital outlay. Any such losses resulting therefrom could materially and adversely affect our financial condition and results of operations. Many of our potential income generating investments are in companies or assets that have limited commercialized revenue-generating products, which may negatively impact our investment returns. In anticipation of the expiration of our Queen et al. patents, we have made and will likely continue to make investments in income-generating assets, such as loans in exchange for a profit share or royalty streams, in the healthcare industries, many of which investments are in companies that, at the time of investment, have limited or no commercialized revenue-generating products. If the assets are not successfully commercialized, the value of our investments will be negatively affected. The ultimate success of our investments in many of our potential revenue generating assets in these industries will depend on the ability of the counterparty to innovate, develop and commercialize their products, in increasingly competitive and highly regulated markets. Their inability to do so would negatively affect our investment. In addition, in connection with many of our potential income- generating investments, we are dependent, to a large extent, on third parties to enforce certain rights for our benefit. For example, we acquired certain royalty rights from Depomed, which, as the licensor of certain patents, retains various rights, including the contractual right to audit its licensees and to ensure those licensees are complying with the terms of the underlying license agreements. Depomed also retains full responsibility to protect and maintain the intellectual property rights underlying the licenses. While we have contractual rights to require Depomed to take action regarding many of these rights, because Depomed’s economic interest in the license agreements is limited, it may not enforce or protect those rights as it otherwise would have had it retained the full economic interest in the payments under the license agreements. Moreover, in respect of the royalty stream relating to the Glumetza diabetes medication that we acquired from Depomed, which is the royalty right producing the highest revenues from the Depomed acquired royalties, U.S. patent protection for this product is expected to begin to expire in September 2016, and under settlement agreements to which Depomed is a party, certain manufacturers of generic products will be permitted to enter the market starting in February and August 2016. The lack of liquidity in our acquisitions may adversely affect our business and, if we need to sell any of our acquired assets, we may not be able to do so at a favorable price. As a result, we may suffer losses. We generally acquire in patents, royalty rights and debt instruments that have limited secondary resale markets. The illiquidity of most of our assets may make it difficult for us to dispose of them at a favorable price and, as a result, we may suffer losses if we are required to dispose of any or all such assets in a liquidation or otherwise. In addition, if we liquidate all or a portion of our assets quickly or in connection with a liquidation, we may realize significantly less than the value at which we had previously recorded these assets. We may use a certain amount of cash from time to time in order to satisfy the obligations relating to our convertible notes. The maturity or conversion of any of our convertible notes may adversely affect our financial condition and operating results, which could adversely affect the amount or timing of dividends to our stockholders. As of December 31, 2013, $180.0 million in principal remained outstanding under our Series 2012 Notes and $155.3 million in principal remained outstanding under our May 2015 Notes. At maturity, we will have to pay the holders of such notes the full aggregate principal amount of the convertible notes, then outstanding. For example, on February 15, 2015, we will have to pay the full aggregate principal amount of our Series 2012 Notes, $180.0 million as of December 31, 2013. Holders of the May 2015 Notes and Series 2012 Notes may convert their notes at their option under the following circumstances: (i) during any fiscal quarter commencing after the fiscal quarter ending June 30, 2011, in the case of our May 2015 Notes, and December 31, 2011, in the case of our Series 2012 Notes, 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; (ii) 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; or (iii) upon the occurrence of specified corporate events. The holders of the May 2015 Notes and Series 2012 Notes may convert their notes at their option during the quarter ended March 31, 2014, as the last reported sale price of our common stock for at least 20 trading days in the period of 30 consecutive trading days ending on December 31, 2013, exceeded 130% of the conversion price for the notes. On and after November 1, 2014, in the case of our May 2015 Notes, and August 15, 2014, in the case of our Series 2012 Notes, holders may convert their notes at any time, regardless of the foregoing circumstances. These notes are net-share settled. If one or more holders elect to convert their notes when conversion is permitted, we would be required to make cash payments to satisfy up to the face value of our conversion obligation in respect of each note, which could adversely affect our liquidity. In 21 addition, even if holders do not elect to convert their May 2015 Notes or Series 2012 Notes, because our May 2015 Notes and Series 2012 Notes are net share settled, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of our May 2015 Notes and Series 2012 Notes as a current rather than long-term liability, which could result in a material reduction of our net working capital. We may use a certain amount of cash from time to time in order to satisfy these repurchase or other obligations relating to the convertible notes which could adversely affect the amount or timing of any distribution to our stockholders or any income generating transactions. In addition, we may redeem (except in the case of our Series 2012 Notes that are unredeemable by us), repurchase or otherwise acquire the convertible notes in the open market in the future, any of which could adversely affect the amount or timing of any cash distribution to our stockholders. The conversion or any future exchanges of any of our May 2015 Notes or our Series 2012 Notes into shares of our common stock would have a dilutive effect that could cause our stock price to go down. Our May 2015 Notes, until November 1, 2014, and our Series 2012 Notes, until August 15, 2014, are convertible into shares of our common stock only if specified conditions are met and thereafter convertible at any time, at the option of the holder. We have reserved shares of our authorized common stock for issuance upon conversion of these convertible notes. Upon conversion, the principal amount is due in cash, and to the extent that the conversion value exceeds the principal amount, the difference is due in shares of common stock. If any or all of these convertible notes are converted into shares of our common stock, our existing stockholders will experience immediate dilution of voting rights and our common stock price may decline. Furthermore, the perception that such dilution could occur may cause the market price of our common stock to decline. The conversion rate as of December 31, 2013, for our Series 2012 Notes is 182.598 shares of common stock per $1,000 principal amount or a conversion price of approximately $5.48 per share of common stock and the conversion rate for our May 2015 Notes is 159.9165 shares of common stock per $1,000 principal amount, or a conversion price of approximately $6.25 per share of common stock. Because the conversion rates of these convertible notes adjust upward upon the occurrence of certain events, such as a dividend payment, our existing stockholders may experience more dilution if any or all of these convertible notes are converted into shares of our common stock after the adjusted conversion rates became effective. We entered into purchased call option and warrant transactions in connection with the issuance of our May 2015 Notes and February 2018 Notes that may affect the value of our common stock. In connection with the issuance of our May 2015 Notes and February 2018 Notes, we entered into purchased call option transactions. Separately, we also entered into warrant transactions at that time. The purchased call option transactions are expected to reduce the potential dilution with respect to our common stock upon conversion of our May 2015 Notes and February 2018 Notes. The warrant transactions could separately have a dilutive effect from the issuance of our common stock pursuant to the warrants. The purchased call option and warrant transactions are accounted for as an adjustment to our stockholders’ equity (deficit). In connection with hedging these transactions, the counterparties to the hedge transactions or their respective affiliates may enter into, or may unwind, various derivative transactions and/or purchase or sell our common stock in secondary market transactions prior to maturity of our May 2015 Notes and February 2018 Notes (and are likely to do so during any cash settlement averaging period related to any conversion of our May 2015 Notes and February 2018 Notes). Such activities could have the effect of decreasing the trading price of our common stock during any cash settlement averaging period related to a conversion of our May 2015 Notes and February 2018 Notes. In addition, we intend to exercise the purchased call options whenever May 2015 Notes and February 2018 Notes are converted, if ever. In order to unwind their hedge positions with respect to those exercised options, the hedge counterparties or their respective affiliates may sell shares of our common stock in secondary market transactions or unwind various derivative transactions with respect to our common stock during the cash settlement averaging period for the converted notes. The effect, if any, of any of these transactions and activities on the trading price of our common stock will depend, in part, on market conditions and cannot be ascertained at this time, but any of these activities could adversely affect the value of our common stock. Further, a failure by the hedge counterparties or their respective affiliates (due to bankruptcy or otherwise) to pay or deliver, as the case may be, amounts owed to us under the purchased call option transactions will not reduce the consideration we are required to deliver to a holder upon its conversion of our May 2015 Notes and February 2018 Notes and may result in an increase in dilution with respect to our common stock. 22 Changes in the third-party reimbursement environment may affect product sales from which we receive royalty revenues. Sales of products from which we receive royalties and our borrowers generate revenues will depend significantly on the extent to which reimbursement for the cost of such products and related treatments will be available to physicians and patients from various levels of U.S. and international government health authorities, private health insurers and other organizations. Third-party payers and government health administration authorities increasingly attempt to limit and/or regulate the reimbursement of medical products and services, including branded prescription drugs. Changes in government legislation or regulation, such as the Affordable Care Act; the Health Care and Education Reconciliation Act of 2010; the Medicare Improvements for Patients and Providers Act of 2009 and the Medicare, Medicaid and State Children’s Health Insurance Program Extension Act of 2007 and changes in formulary or compendia listing or changes in private third-party payers’ policies toward reimbursement for such products may reduce reimbursement of the cost of such products to physicians, pharmacies and distributors. Decreases in third- party reimbursement could reduce usage of such products and sales to collaborators, which may have a material adverse effect on our royalties and the revenues of our borrowers. In addition, macroeconomic factors may affect the ability of patients to pay or co-pay for costs or otherwise pay for products from which we generate royalties and our borrowers generate revenues by, for example, decreasing the number of patients covered by insurance policies or increasing costs associated with such policies. Our revenues, cash flows and operating results will likely fluctuate in future periods. Our revenues and income may be unpredictable and fluctuate because they depend upon, among other things, the rate of growth of our royalties and the timing of interest and principal payments, as well as early repayment of our notes receivable. To protect unpredictable and fluctuating cash flows, we may need to carry additional cash on our balance sheet at very low interest rates or enter into short-term financings, such as our Term Loan. Until August 15, 2013, the Genentech agreement provided for a tiered royalty structure. The royalty rate Genentech paid on 95% of the underlying gross U.S.-based Sales in a given calendar year decreased on incremental U.S.-based Sales above certain net sales thresholds. As a result of the tiered royalty structure, Genentech’s average annual royalty rate for a given year declined as Genentech’s U.S.-based Sales increase during that year. Because we receive royalties one quarter in arrears, the average royalty rate for the payments we received from Genentech in the second calendar quarter, which would be for Genentech’s sales from the first calendar quarter, were higher than the average royalty rate for following quarters. The average royalty rate for payments we received from Genentech were generally lowest in the fourth quarter and first calendar quarter of the following year, which would be for Genentech’s sales from the third and fourth calendar quarter, when Genentech’s U.S.-based Sales bore royalties at a 1% royalty rate. With respect to the ex-U.S.-based Manufacturing and Sales, the royalty rate that we received from Genentech was a fixed rate of 3% based on 95% of the underlying gross ex-U.S.-based Manufacturing and Sales. The mix of U.S.-based Sales and ex-U.S.-based Manufacturing and Sales fluctuated in the past. We may experience increases and decreases in our royalty revenues due to fluctuations in foreign currency exchange rates and we may be unsuccessful in our attempts to mitigate this risk. A material portion of our royalties are calculated based on sales in currencies other than the U.S. dollar. Fluctuations in foreign currency rates, particularly the Euro, relative to the U.S. dollar can significantly affect our revenues and operating results. 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. For example, 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 exchange rates remained unchanged. 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 is 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 the current quarter than in the prior year. To compensate for Euro currency fluctuations, we hedge Euro currency exposures with Euro forward and option contracts, to offset the risks associated with these Euro currency exposures. We may suspend the use of these contracts from time to time or we may be unsuccessful in our attempt to hedge our Euro currency risk. We will continue to experience foreign currency related fluctuations in our royalty revenues in certain instances when we do not enter into foreign currency exchange contracts or where it is not possible or cost effective to hedge our foreign currency related exposures. Currency related fluctuations in our royalty revenues will vary based on the currency exchange rates associated with these exposures and changes in those rates, whether we have entered into foreign currency exchange contracts to offset these exposures and other factors. All of these factors could 23 materially impact our results of operations, financial position and cash flows, the timing of which is variable and generally outside of our control. We must attract, retain and integrate key employees in order to succeed. It may be difficult to recruit, retain and integrate key employees. To be successful, we must attract, retain and integrate qualified personnel. Our business is intellectual property asset management, investing in income generating assets and maximizing the value of our patent portfolio and related assets, which requires only a small number of employees. Due to the potential short-term nature and remote location of our company, it may be difficult for us to recruit and retain qualified personnel. If we are unsuccessful in attracting, retaining and integrating qualified personnel, our business could be impaired. Our agreements with Facet may not reflect terms that would have resulted from arm’s-length negotiations between unaffiliated third parties. The agreements associated with the Spin-Off of Facet in December 2008, including the Separation and Distribution Agreement, Tax Sharing and Indemnification Agreement and Cross License Agreement, were negotiated in the context of the Spin-Off while Facet was still part of PDL and, accordingly, may not reflect more favorable terms that may have resulted from arm’s-length negotiations between unaffiliated third parties. We may have obligations for which we may not be able to collect under our indemnification rights from Facet. Under the terms of the Separation and Distribution agreement with Facet, we and Facet agreed to indemnify the other from and after the Spin-Off with respect to certain indebtedness, liabilities and obligations that were retained by our respective companies. These indemnification obligations could be significant. The ability to satisfy these indemnities, if called upon to do so, will depend upon the future financial strength of each of our companies. We cannot assure you that, if Facet has to indemnify us for any substantial obligations, Facet will have the ability to satisfy those obligations. If Facet does not have the ability to satisfy those obligations, we may be required to satisfy those obligations instead. For example, in connection with the Spin-Off, we entered into amendments to the leases for the facilities in Redwood City, California, which formerly served as our corporate headquarters, under which Facet was added as a co-tenant under the leases and a Co-Tenancy Agreement under which Facet agreed to indemnify us for all matters related to the leases attributable to the period after the Spin-Off date. Should Facet default under its lease obligations, we would be held liable by the landlord as a co-tenant and, thus, we have in substance guaranteed the payments under the lease agreements for the Redwood City facilities, the disposition of which could have a material adverse effect on the amount or timing of any distribution to our stockholders. As of December 31, 2013, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately $90.2 million. We would also be responsible for lease related payments including utilities, property taxes and common area maintenance which may be as much as the actual lease payments. In April 2010, Abbott Laboratories acquired Facet and renamed the company Abbott Biotherapeutics Corp., and in January 2013, Abbott Biotherapeutics Corp. was renamed AbbVie Biotherapeutics, Inc. and spun off from Abbott as a subsidiary of AbbVie Inc. We do not know how Abbott’s acquisition of Facet will impact our ability to collect under our indemnification rights or whether Facet’s ability to satisfy its obligations will change. In addition, we have limited information rights under the Co-Tenancy Agreement. As a result, we are unable to determine definitively whether Facet continues to occupy the space and whether it has subleased the space to another party. See “Item 2—Properties.” ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 2. PROPERTIES We lease approximately 4,800 square feet of office space in Incline Village, Nevada, which serves as our corporate headquarters. The lease expires in May 2014. We may, at our option, extend the term of this lease. In July 2006, we entered into two leases and a sublease for the facilities in Redwood City, California, which formerly served as our corporate headquarters and cover approximately 450,000 square feet of office space. Under the amendments to the leases entered into in connection with the Spin-Off, Facet was added as a co-tenant under the leases. As a co-tenant, Facet is bound by all of the terms and conditions of the leases. PDL and Facet are jointly and severally liable for all obligations under the leases, including the payment of rental obligations. However, we also entered into a Co-Tenancy Agreement with Facet in connection with the Spin-Off and the lease amendments under which we assigned to Facet all rights under the leases, including, but not 24 limited to, the right to amend the leases, extend the lease term or terminate the leases, and Facet assumed all of our obligations under the leases. Under the Co-Tenancy Agreement, we also relinquished any right or option to regain possession, use or occupancy of these facilities. Facet agreed to indemnify us for all matters associated with the leases attributable to the period after the Spin-Off date and we agreed to indemnify Facet for all matters associated with the leases attributable to the period before the Spin-Off date. In addition, in connection with the Spin-Off, the sublease was assigned by PDL to Facet. In April 2010, Abbot laboratories acquired Facet and later renamed the entity AbbVie Biotheraputics, Inc. To date, AbbVie has satisfied all obligations under the Redwood City lease. ITEM 3. LEGAL PROCEEDINGS Genentech / Roche Matter Settlement Agreement 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. On January 31, 2014, we entered into a settlement agreement with Genentech and Roche which resolves all outstanding legal disputes between the parties, including our Nevada litigation with Genentech relating to an August 2010 facsimile sent by Genentech on behalf of Roche and Novartis asserting its products do not infringe on PDL’s SPC’s, and our arbitration proceedings with Genentech related to the audit of royalties on sales. Under the terms of the Settlement Agreement, effective retroactively to August 15, 2013, Genentech will pay a fixed royalty rate of 2.125 percent on worldwide sales of all its licensed products, as compared to the previous tiered royalty rate in the U.S and the fixed rate on all ex-U.S. based manufactured and sold licensed products. Pursuant to the Settlement Agreement, Genentech and Roche confirmed that Avastin, Herceptin, Lucentis, Xolair and Perjeta are licensed products as defined in the relevant license agreements between the parties, and further agreed that Kadcyla and Gazyva are licensed products. Genentech will pay these royalties on all worldwide sales of Avastin, Herceptin, Xolair, Perjeta and Kadcyla occurring on or before December 31, 2015. With respect to Lucentis, Genentech will owe no royalties on U.S. sales occurring after June 30, 2013, and will pay a royalty of 2.125 percent on all ex-U.S. sales occurring on or before December 28, 2014. The royalty term for Gazyva remains unchanged from the existing license agreement pertaining thereto. The Settlement Agreement precludes Genentech and Roche from challenging the validity of PDL’s patents, including its SPCs in Europe, from contesting their obligation to pay royalties, from contesting patent coverage for Avastin, Herceptin, Lucentis, Xolair, Perjeta, Kadcyla and Gazyva and from assisting or encouraging any third party in challenging PDL’s patents and SPCs. The Settlement Agreement further outlines the conduct of any audits initiated by PDL of the books and records of Genentech in an effort to ensure a full and fair audit procedure. Finally, the agreement clarifies that the sales amounts from which the royalties are calculated does not include certain taxes and discounts. The Settlement Agreement provides greater certainty for each of the parties in terms of the royalty rate payable under the agreement and the period over which they will be payable. PDL expects to recognize royalty revenue on the licensed products until the first quarter of 2016. Additionally, the settlement terms provide for a better definition of revenues and audit inspection procedures related to the arbitration dispute filed by PDL. Other Legal Proceedings In addition, from time to time, we may be 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. 25 ITEM 4.

MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Our common stock trades on the NASDAQ Global Select Market under the symbol “PDLI.” Prices indicated below are the high and low intra-day sales prices per share of our common stock as reported by the NASDAQ Global Select Market for the periods indicated. 2013 First Quarter ............................................................................................................................. $ Second Quarter ......................................................................................................................... $ Third Quarter............................................................................................................................ $ Fourth Quarter .......................................................................................................................... $ 2012 First Quarter ............................................................................................................................. $ Second Quarter ......................................................................................................................... $ Third Quarter............................................................................................................................ $ Fourth Quarter .......................................................................................................................... $ High Low 7.58 8.48 8.45 10.21 6.60 6.68 7.86 8.43 $ $ $ $ $ $ $ $ 6.50 7.22 7.63 7.52 6.00 6.03 6.49 6.95 As of February 14, 2014, we had approximately 136 common stockholders of record. Most of our outstanding shares of common stock are held of record by one stockholder, Cede & Co., as nominee for the Depository Trust Company. Many brokers, banks and other institutions hold shares of common stock as nominees for beneficial owners which deposit these shares of common stock in participant accounts at the Depository Trust Company. The actual number of beneficial owners of our stock is likely significantly greater than the number of stockholders of record; however, we are unable to reasonably estimate the total number of beneficial owners. 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. On January 29, 2014, our board of directors declared a regular quarterly dividend of $0.15 per share of common stock on March 12, June 12, September 12 and December 12 of 2014 to stockholders of record on March 5, June 5, September 5 and December 5 of 2014, the record dates for each of the dividend payments, respectively. On January 23, 2013, our board of directors declared a regular quarterly dividend of $0.15 per share of common stock. On March 12, June 12, September 12 and December 12 of 2013, we paid quarterly cash dividends of approximately $21.0 million or $0.15 per share 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 January 18, 2012, our board of directors declared a regular quarterly dividend of $0.15 per share of common stock. On March 14, June 14, September 14 and December 14 of 2012, we paid quarterly cash dividends of approximately $21.0 million or $0.15 per share to stockholders of record on March 7, June 7, September 7 and December 7 of 2012, the record dates for each of the dividend payments, respectively. Comparison of Stockholder Returns The line graph below compares the cumulative total stockholder return on our common stock between December 31, 2008, and December 31, 2013, with the cumulative total return of (i) the NASDAQ Biotechnology Index and (ii) the NASDAQ Composite Index over the same period. This graph assumes that $100.00 was invested on December 31, 2008, in our common stock at the closing sales price for our common stock on that date and at the closing sales price for each index on that date and that all 27 dividends were reinvested. Stockholder returns over the indicated period should not be considered indicative of future stockholder returns and are not intended to be a forecast.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 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, acquiring 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 continues to pursue this strategic initiative for which it has already invested approximately $500 million to date. 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 Update to Challenges against the Queen et al. Patents in the United States and Europe Genentech / Roche Matter Settlement Agreement On January 31, 2014, we entered into a settlement agreement with Genentech and Roche which resolves all outstanding legal disputes between the parties, including our Nevada litigation with Genentech relating to an August 2010 facsimile sent by Genentech on behalf of Roche and Novartis asserting its products do not infringe on PDL’s SPC’s, and our arbitration proceedings with Genentech related to the audit of royalties on sales. Under the terms of the Settlement Agreement, effective retroactively to August 15, 2013, Genentech will pay a fixed royalty rate of 2.125 percent on worldwide sales of all its licensed products, as compared to the previous tiered royalty rate in the U.S and the fixed rate on all ex-U.S. based manufactured and sold licensed products. Pursuant to the agreement, Genentech and Roche confirmed that Avastin, Herceptin, Lucentis, Xolair and Perjeta are licensed products as defined in the relevant license agreements between the parties, and further agreed that Kadcyla and Gazyva are licensed products. Genentech will pay these royalties on all worldwide sales of Avastin, Herceptin, Xolair, Perjeta and Kadcyla occurring on or before December 31, 2015. With respect to Lucentis, Genentech will owe no royalties on U.S. sales occurring after June 30, 2013, and will pay a royalty of 2.125 percent on all ex-U.S. sales occurring on or before December 28, 2014. The royalty term for Gazyva remains unchanged from the existing license agreement pertaining thereto. The agreement precludes Genentech and Roche from challenging the validity of PDL’s patents, including its SPCs in Europe, from contesting their obligation to pay royalties, from contesting patent coverage for Avastin, Herceptin, Lucentis, Xolair, Perjeta, Kadcyla and Gazyva and from assisting or encouraging any third party in challenging PDL’s patents and SPCs. The agreement further outlines the conduct of any audits initiated by PDL of the books and records of Genentech in an effort to ensure a full and fair audit procedure. Finally, the agreement clarifies that the sales amounts from which the royalties are calculated does not include certain taxes and discounts. 30 The settlement agreement provides greater certainty for each of the parties in terms of the royalty rate payable under the agreement and the period over which they will be payable. PDL expects to recognize royalty revenue on the licensed products until the first quarter of 2016. Additionally, the settlement terms provide for a better definition of revenues and audit inspection procedures related to the arbitration dispute filed by PDL. Notes and Other Long-term Receivables Wellstat Diagnostics Note Receivable and Credit Agreement In March 2012, the Company executed a $7.5 million two-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 year ended December 31, 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 to receive quarterly royalty payments based on a low double digit royalty rate of Wellstat Diagnostics' net revenues upon successful commercialization. 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, if any, of an affiliated 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 of the note receivable which 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. 31 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 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. 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. At December 31, 2013, and 2012, the carrying value of the note was included in non-current assets. As of December 31, 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 direct the activities of Wellstat Diagnostics that most significantly impacts Wellstat Diagnostics economic performance and is not the primary beneficiary of Wellstat Diagnostics; therefore, Wellstat Diagnostics is not subject to consolidation. As of December 31, 2013, the carrying value of all amounts advanced to Wellstat Diagnostics was $47.7 million, which was recorded in notes receivable. As of December 31, 2013, the maximum loss exposure was $47.7 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 December 31, 2013. AxoGen 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 (assigned interests). 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 $2.5 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 assigned interests 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 with a third party. 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 assigned interests 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. 32 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 $1.1 million and $0.6 million as of December 31, 2013 and 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 $0.5 million related to the change in the estimated fair value of embedded derivative during the year ended December 31, 2013. 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 consolidated balance sheet. As of December 31, 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 (loss). 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. 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. 33 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). Within 9 months after the occurrence of the tranche two milestone, Durata may request up to a single additional $30 million borrowing. Until the occurrence of the tranche two milestone, outstanding borrowings under tranche one bear interest at the rate of 14.0% per annum, payable quarterly in arrears. Upon occurrence of the tranche two milestone, the interest rate of the loans will decrease to 12.75%. Principal repayment will commence on the fifth interest payment date, March 31, 2015. The principal amount outstanding will be repaid quarterly over the remainder of the loans in an increasing percentage of the principal outstanding at commencement of repayment. The loans will mature on October 31, 2018. Durata may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans. The Company is entitled to receive a fee in addition to the prepayment penalty in the event that Durata undergoes a change in control. The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Durata. Direct Flow Medical Credit Agreement 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 (tranche one), 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 tranche two milestone), the Company will loan to Direct Flow Medical an additional $15.0 million, net of fees. Until the occurrence of the tranche two milestone, outstanding borrowings under tranche one bear interest at the rate of 15.5% per annum, payable quarterly in arrears. Upon occurrence of the tranche two milestone, the interest rate of the loans will decrease to 13.5%. Principal repayment will commence on the twelfth interest payment date, September 30, 2016. The principal amount outstanding at commencement of repayment will be repaid in equal installments until final maturity of the loans. The loans will mature on November 5, 2018. Direct Flow Medical may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans. The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Direct Flow Medical and any of its subsidiaries. Paradigm Spine On February 14, 2014, PDL entered into a credit agreement with Paradigm Spine, LLC, under which PDL made available to Paradigm up to $75 million to be used by Paradigm to refinance its existing credit facility and expand its domestic commercial operations. A portion of the amount available under the agreement in an aggregate principal amount equal to $50 million, net of fees, was funded at the close of the transaction. In the event that certain specified sales and other milestones occur before December 31, 2014, PDL will fund Paradigm between an additional $6.25 million and $12.5 million, at Paradigm’s discretion. In the event that additional specified sales and other milestones occur before June 30, 2015, PDL will fund up to an additional $12.5 million also at Paradigm’s discretion. Borrowings under the credit agreement bear interest at the rate of 13.0% per annum, payable quarterly in arrears. Principal repayment will commence on the eleventh interest payment date, September 30, 2016. The principal amount outstanding at commencement of repayment will be repaid in equal installments until final maturity of the loans. The loans will mature on February 14, 2019, or, if Paradigm has achieved the first milestone and the additional loan amount is provided to Paradigm, the loans will mature on August 14, 2019. Paradigm may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans. The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Paradigm and its domestic subsidiaries and, initially, certain assets of Paradigm’s German subsidiaries. 34 Intangible Assets 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. The royalty agreement terminates on the third anniversary following the date upon which the later of the following occurs: (a) October 25, 2021, or (b) at such time as no royalty payments remain payable under any license agreement and each of the license agreements has expired by its terms. Convertible Notes Series 2012 Notes We have actively worked to restructure the Company’s capital and reduce the potential dilution associated with our convertible notes. As part of those efforts, in January 2012, we exchanged and subsequently retired $169.0 million aggregate principal amount of our February 2015 Notes for an identical principal amount of our 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 exchanged and subsequently 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 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 is due in cash, and to the extent that the conversion value exceeds the principal amount, the difference is due in shares of our common stock. The effect of issuing $179.0 million aggregate principal of our Series 2012 Notes with the net share settle feature in exchange for our February 2015 Notes was the reduction of 27.8 million shares of potential dilution to our stockholders at the time of the exchange. On February 5 and 6, 2014, the Company entered into separate, privately negotiated exchange and purchase agreements under which it retired $131.7 million in aggregate principal of the Company’s outstanding Series 2012 Notes. The exchange agreements provided for the issuance, by the Company, of shares of common stock and a cash payment for the Series 2012 Notes being exchanged, and the purchase agreement provided for a cash payment for the Series 2012 Notes being repurchased. The Company issued a total of 20.3 million shares of its common stock and paid an aggregate cash payment of $34.2 million pursuant to the exchange and repurchase agreements. 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. 35 February 2018 Notes On February 6, 2014, the Company agreed to sell $260.87 million aggregate principal amount of its 4.00% Convertible Senior Notes due February 1, 2018, in an underwritten public offering. The conversion rate of the February 2018 Notes will initially be 109.1048 shares of common stock per $1,000 principal amount of the February 2018 Notes equivalent to an initial conversion price of approximately $9.17 per share of common stock. The conversion rate, subject to increase under certain circumstances, will not be increased in respect of regular quarterly cash dividends paid by us that do not exceed $0.15 per share. On February 12, 2014, the Company issued $300 million aggregate principal amount of February 2018 Notes, which included $39.13 million aggregate principal amount of February 2018 Notes issued pursuant to the exercise of the underwriters’ overallotment option to purchase additional 2018 Notes. In connection with the offering of the February 2018 Notes, PDL entered into privately negotiated convertible note hedge transactions with affiliates of RBC Capital Markets and Well Fargo Securities (“hedge counterparties”) and privately negotiated warrant transactions with the hedge counterparties relating to the same number of shares of PDL’s common stock. Effect of December 12, 2013, Dividend Payment on Conversion Rates for the Convertible Notes In connection with the December 12, 2013, dividend payment, the conversion rates for our convertible notes adjusted as follows: Convertible Notes Series 2012 Notes ................................... May 2015 Notes...................................... Conversion Rate per $1,000 Principal Amount Approximate Conversion Price Per Common Share 182.598 159.9165 $ $ 5.48 6.25 Effective Date December 3, 2013 December 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. Term Loan On October 28, 2013, PDL entered into the Term loan for $75 million, with a term of one year. 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. As of December 31, 2013, the interest rate was 2.24%. Interest and principal payments associated with the Term Loan 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 Term Loan, except as otherwise provided. The Company’s obligations under the Term Loan are secured by a lien on a substantial portion of its assets. The Term Loan contains affirmative and negative covenants that the Company believes are usual and customary for a senior secured credit agreement. The Term loan 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 Term Loan and compliance with which may be necessary to take certain corporate actions. The Term Loan contains events of default that the Company believes are usual and customary for a senior secured credit agreement 36 2014 Dividends On January 29, 2014, 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 2014 to stockholders of record on March 5, June 5, September 5 and December 5 of 2014, the record dates for each of the dividend payments, respectively. At the beginning of each fiscal year, our board of directors sets the Company’s total annual dividend payment for the 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 the dividend. Critical Accounting Policies and Estimates The preparation of financial statements and related disclosures in conformity with GAAP and the Company's discussion and analysis of its financial condition and operating results require the Company's management to make judgments, assumptions and estimates that affect the amounts reported in its consolidated financial statements and accompanying notes. Note 2, “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K describes the significant accounting policies and methods used in the preparation of the Company's consolidated financial statements. Management bases its estimates on historical experience and on various other assumptions it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates and such differences may be material. Management believes the Company's critical accounting policies and estimates are those related to royalty revenues, foreign currency hedging, income taxes, notes receivable, convertible notes, and lease guarantee. Management considers these policies critical because they are both important to the portrayal of the Company's financial condition and operating results, and they require management to make judgments and estimates about inherently uncertain matters. Royalty Revenues Patent License Agreements Under most of our patent license agreements, we receive royalty payments based upon our licensees’ net sales of covered products. Generally, under these agreements we receive royalty reports and payments from our licensees approximately one quarter in arrears, generally in the second month of the quarter after the licensee has sold the income generating product or products. We recognize royalty revenues when we can reliably estimate such amounts and collectability is reasonably assured. As such, we generally recognize royalty revenues in the quarter reported to us by our licensees. Therefore, royalty revenues are generally recognized one quarter following the quarter in which sales by our licensees occurred. Under this accounting policy, the royalty revenues we report are not based upon our estimates and are typically reported in the same period in which we receive payment from our licensees. We may also receive annual license maintenance fees from licensees of our Queen et al. patents prior to patent expiry as well as periodic milestone payments, payable at the election of the licensee, to maintain the license in effect. We have no performance obligations with respect to such fees. Maintenance fees are recognized as they are due and when payment is reasonably assured. Total milestone payments in each of the last several years have been less than 1% of total revenue. Acquired Royalty Revenues We receive royalty payments based upon net sales of Depomed's covered products. Generally, under these agreements we receive royalty reports and payments from Depomed approximately one month in arrears. We recognize royalty revenues when we can reliably estimate such amounts and collectability is reasonably assured. As such, we generally recognize royalty revenues in the month reported to us by Depomed. Therefore, royalty revenues are generally recognized one month following the month in which covered product sales occurred. Under this accounting policy, the royalty revenues we report are not based upon our estimates and are typically reported in the same period in which we receive payment from our licensees. 37 Foreign Currency Hedging We hedge certain Euro-denominated currency exposures related to our licensees’ product sales with Euro forward contracts. In general, these contracts are intended to offset the underlying Euro market risks in our royalty revenues. We do not enter into speculative foreign currency transactions. We designate foreign currency exchange contracts used to hedge royalty revenues based on underlying Euro-denominated sales as cash flow hedges. At the inception of the hedging relationship and on a quarterly basis, we assess hedge effectiveness. The fair value of the Euro forward contracts is estimated using pricing models with readily observable inputs from actively quoted markets and is disclosed on a gross basis. The aggregate unrealized gain or loss, net of tax, on the effective portion of the hedge is recorded in stockholders’ 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. The hedge effectiveness is dependent upon the amounts of future royalties and, if future royalties based on Euro are lower than forecasted, the amount of ineffectiveness would be reported in our Consolidated Statements of Income. Income Taxes Our income tax provision is based on income before taxes and is computed using the liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using tax rates projected to be in effect for the year in which the differences are expected to reverse. We record a valuation allowance to reduce our deferred tax assets to the amounts that are more likely than not to be realized. Significant estimates are required in determining our provision for income taxes. Some of these estimates are based on interpretations of existing tax laws or regulations, or the expected results from any future tax examinations. Various internal and external factors may have favorable or unfavorable effects on our future provision for income taxes. These factors include, but are not limited to, changes in tax laws, regulations and/or rates, the results of any future tax examinations, changing interpretations of existing tax laws or regulations, changes in estimates of prior years’ items, past levels of research and development spending, acquisitions, changes in our corporate structure and state of domicile and changes in overall levels of income before taxes all of which may result in periodic revisions to our provision for income taxes. We accrue tax related interest and penalties associated with uncertain tax positions and include these in income tax expense in the Consolidated Statements of Income. We expect that our effective income tax rate going forward will be approximately 35%. We apply the provision of ASC 740, which contains a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. Although we believe we have adequately accrued for our uncertain tax positions, no assurance can be given that the final tax outcome of these matters will not be different. We adjust these accruals in light of changing facts and circumstances, such as the closing of a tax audit. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the impact of uncertain tax positions accrual changes to reserves that are considered appropriate, as well as the related net interest settlement of any particular position, could require the use of cash. In addition, we are subject to the continuous examination of our income tax returns by various taxing authorities, including the Internal Revenue Service and U.S. states. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. Notes and Other Long-Term Receivables Notes receivable and loans originated by us are initially recorded at the amount advanced to the borrower. Notes receivable and loan origination and commitment fees, net of certain origination costs, are recorded as an adjustment to the carrying value of the notes receivable and loans and are amortized over the term of the related financial asset under the effective interest method. Certain of our notes receivable and loans require the borrower to make variable payments which are dependent upon the borrower's sales of specific products. We have elected to use the prospective interest method to account for these notes receivable and loans subsequent to their initial recognition. Under this approach, we recognize the impact of any variations from the expected returns in the period when received. From time to time, we will re-evaluate the expected cash flows and may adjust the effective interest rate prospective from the date of assessment, if the impact of such adjustment could be material to our financial statements. 38 We evaluate the collectability of both interest and principal for each note and loan to determine whether it is impaired. A note or loan is considered to be impaired when, based on current information and events, we determine it is probable that we will be unable to collect all amounts due according to the existing contractual terms. When a note or loan is considered to be impaired, the amount of loss is calculated by comparing the carrying value of the financial asset to the value determined by discounting the expected future cash flows at the loan's effective interest rate. If the loan is collateralized and we expect repayment to be provided solely by the collateral, then the amount of loss is calculated by comparing the carrying value of the financial asset to the estimated fair value of the underlying collateral, less expense to sell. Convertible Notes In 2014, we issued our February 2018 Notes with a net share settlement feature, meaning that upon any conversion, the principal amount will be settled in cash and the remaining amount, if any, will be settled in shares of our common stock. In accordance with accounting guidance for convertible debt instruments that may be settled in cash or other assets on conversion, we will separate the principal balance between the fair value of the liability component and the common stock conversion feature using a market interest rate for a similar nonconvertible instrument at the date of issuance. In 2012, we issued our Series 2012 Notes with a net share settlement feature. In accordance with accounting guidance for convertible debt instruments that may be settled in cash or other assets on conversion, we separated the principal balance between the fair value of the liability component and the common stock conversion feature using a market interest rate for a similar nonconvertible instrument at the date of issuance. Using an assumed borrowing rate of 7.3%, an estimated market interest rate for a similar convertible instrument available to us on the date of issuance, 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. In 2011, we issued our May 2015 Notes with a net share settlement feature. In accordance with accounting guidance for convertible debt instruments that may be settled in cash or other assets on conversion, we separated the principal balance between the fair value of the liability component and the common stock conversion feature using a market interest rate for a similar nonconvertible instrument at the date of issuance. Using an assumed borrowing rate of 7.5%, an estimated market interest rate for a similar convertible 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 $6.6 million to deferred tax liability. 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 under the leases, and a Co-Tenancy Agreement, under which Facet agreed to indemnify us for all matters related to the leases attributable to the period after the Spin-Off date. Should Facet default under its lease obligations, we 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 December 31, 2013, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately $90.2 million. In April 2010, Abbot Laboratories acquired Facet and later renamed the entity AbbVie Biotherapeutics, Inc. If AbbVie 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 recorded a liability of $10.7 million on our Consolidated Balance Sheets as of December 31, 2013 and 2012, for the estimated liability resulting from this guarantee. We prepared a discounted, probability-weighted cash flow analysis to calculate the estimated fair value of the lease guarantee as of the Spin-Off. We were required to make assumptions regarding the probability of Facet’s default on the lease payment, the likelihood of a sublease being executed and the times at which these events could occur. These assumptions are based on information that we received from real estate brokers and the then-current economic conditions, as well as expectations of future economic conditions. The fair value of this lease guarantee was charged to additional paid-in capital upon the Spin-Off and any future adjustments to the carrying value of the obligation will also be recorded in additional paid-in capital. In future periods, we may increase the recorded liability for this obligation if we conclude that a loss, which is larger than the amount recorded, is both probable and estimable. Summary of 2013, 2012 and 2011 Financial Results • Our net income for the years ended December 31, 2013, 2012 and 2011 was $264.5 million, $211.7 million and $199.4 million, respectively; 39 • At December 31, 2013, we had cash, cash equivalents, investments and restricted investments of $99.5 million as compared with $168.7 million at December 31, 2012; and • At December 31, 2013, we had $430.5 million in total liabilities as compared with $348.1 million at December 31, 2012. Revenues Revenues were $442.9 million, $374.5 million and $362.0 million for the years ended December 31, 2013, 2012 and 2011, respectively, and consist of royalty revenues as well as in 2013 and 2011 other license related revenues. During the years ended December 31, 2013, 2012 and 2011, our royalty revenues consisted of royalties and maintenance fees earned on sales of products under license agreements associated with our Queen et al. patents, and during the year ended December 31, 2013, royalty revenues also included $11.2 million in royalties associated with the first two months of recorded royalties from U.S. sales of Glumetza from our Depomed royalty purchase agreement. Over this same time period, our other license related revenues primarily consisted of milestone payments from licensees under our patent license agreements as well as a $10.0 million payment in 2011 from our legal settlement with UCB. Our revenues consist primarily of royalty revenues, which represent more than 95% of total revenues for each of the past three years. Revenues for the years ended December 31, 2013, 2012 and 2011, are 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. A summary of our revenues for the years ended December 31, 2013, 2012 and 2011, is presented below: (Dollars in thousands) 2013 2012 Change from Prior Year % 2011 Change from Prior Year % Revenues Royalties.................................

The licensees with commercial products as of December 31, 2013, are listed below: Licensee Genentech ............................................................................................................................................ Avastin Product Names 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. Under our agreements for the license of rights under our Queen et al. patents, we received a flat-rate or tiered royalty based upon our licensees’ net sales of covered products. Royalty payments are generally due one quarter in arrears, that is, generally in the second month of the quarter after the licensee has sold the royalty-bearing product. Until the August 15, 2013, effective date of 40 the Settlement Agreement, our agreement with Genentech provided for a tiered royalty structure under which the royalty rates Genentech must pay on the U.S.-based Sales in a given calendar year decreased on incremental U.S.-based Sales above certain sales thresholds based on 95% of the underlying gross U.S.-based Sales. As a result of the tiered royalty structure, Genentech’s average annual royalty rate for a given year declined as Genentech’s U.S.-based Sales increased during that year. Because we received royalties in arrears, the average royalty rate for the payments we received from Genentech in our second calendar quarter for Genentech’s sales from the first calendar quarter. The average royalty rate for payments we received from Genentech are generally lowest in our 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 bore royalties at the 1% royalty rate. In 2013, the blended rate for the full year of royalties from Genentech products was a approximately 1.9%. The net sales thresholds and the applicable royalty rates for Genentech’s U.S.-based Sales recognized by us prior to the Settlement Agreement are outlined below: Genentech Products Made or Sold in the U.S. Net sales up to $1.5 billion ....................................................................................................................................... Net sales between $1.5 billion and up to $2.5 billion............................................................................................... Net sales between $2.5 billion and up to $4.0 billion............................................................................................... Net sales exceeding $4.0 billion ............................................................................................................................... Royalty Rate 3.0% 2.5% 2.0% 1.0% With respect to the ex-U.S.-based Manufacturing and Sales, prior to August 15, 2013, the royalty rate that we received from Genentech was a fixed rate of 3% based on 95% of the underlying gross ex-U.S.-based Manufacturing and 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 mix of net ex-U.S.-based Sales and net ex-U.S.-based Manufacturing and Sales for the Genentech Products, as outlined below, is based on information provided to us by Genentech.

The growth is primarily driven by increased net sales of Avastin, Herceptin, Lucentis, Xolair and Actemra by our licensees, along with the 41 addition of the royalty payments from the Company's purchase of Depomed's diabetes-related royalties. Net sales of Avastin, Herceptin, Lucentis and Xolair are subject to a tiered royalty rate for product that is U.S.-based Sales and a flat royalty rate of 3% for product that is ex-U.S.-based Manufacturing and Sales. • Reported net sales of Avastin increased $0.6 billion or 10% compared to the same period for the prior year. • Reported net sales of Herceptin increased $0.4 billion or 6% compared to the same period for the prior year. • Reported Lucentis sales increased $0.4 billion or 10% compared to the same period for the prior year. • Reported Xolair sales increased $0.2 billion or 14% compared to the same period for the prior year. For the year ended December 31, 2012, compared to December 31, 2011 Royalty revenues increased 7% for the year ended December 31, 2012, when compared to the same period in 2011. The growth is primarily driven by increased net sales of Lucentis, Herceptin, Xolair and Tysabri by our licensees. Net sales of Avastin, Herceptin, Lucentis, and Xolair were subject to a tiered royalty rate for product that is U.S.-based Sales and a flat royalty rate of 3% for product that is ex-U.S.-based Manufacturing and Sales. • Reported net sales of Herceptin increased $0.4 billion or 7% compared to the same period for the prior year. • Reported Lucentis sales increased $0.4 billion or 11% compared to the same period for the prior year. • Reported sales of Tysabri increased $0.1 billion or 8% compared to the same period for the prior year. Tysabri royalties are determined at a flat rate as a percent of the sales regardless of location of manufacture or sale. • Reported net sales of Avastin increased $0.1 billion or 1% compared to the same period for the prior year. The following table summarizes the percentage of our total revenues earned from our licensees’ net product sales, which individually accounted for 10% or more of our total revenues for the years ended December 31, 2013, 2012 and 2011: Licensee Genentech .................................................................... Avastin Product Name Lucentis Elan .............................................................................. Tysabri Herceptin Year Ended December 31, 2012 2011 2013 33% 32% 10% 11% 32% 34% 12% 13% 31% 33% 15% 12% 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. For the year ended December 31, 2013, we hedged certain Euro-denominated currency exposures related to our licensees’ product sales with Euro forward contracts. We designate foreign currency exchange contracts used to hedge royalty revenues based on underlying Euro-denominated sales as cash flow hedges. The aggregate unrealized gain or loss, net of tax, on the effective portion 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 42 earnings. For the years ended December 31, 2013, 2012 and 2011, we recognized ($2.3) million, ($2.9) million and $1.0 million in royalty revenues from our Euro contracts, respectively. Operating Expenses A summary of our operating expenses for the years ended December 31, 2013, 2012 and 2011, is presented below: (Dollars in thousands, except for percentages) 2013 2012 Change from Prior Year % 2011 Change from Prior Year % Cost of royalty revenues (amortization of intangible asset).............................

For the year ended December 31, 2012, compared to December 31, 2011 The increase in operating expenses was a result of increased legal expenses of $3.7 million mostly related to litigation, a $1.4 million increase in professional services related to our efforts to acquire income generating assets and a $1.4 million increase in compensation related expenses. Non-operating Expense, Net A summary of our non-operating expense, net, for the years ended December 31, 2013, 2012 and 2011, is presented below: (Dollars in thousands) 2013 2012 Change from Prior Year % 2011 Change from Prior Year % Loss on retirement or conversion of convertible notes..

The approximate $12.1 million increase in interest income to $19.2 million is a result of the increase in loans to late stage healthcare companies as part of our strategy to acquire income generating assets. The increase in 43 interest expense consisted primarily of non-cash interest expense as we were required to compute interest expense using the interest rate for similar nonconvertible instruments in accordance with the accounting guidance for convertible debt instruments that may be settled in cash or other assets on conversion. Non-cash interest expense, in accordance with the accounting guidance, for the Series 2012 Notes, May 2015 Notes and our term loan was $11.2 million for the year ended December 31, 2013, and for the Series 2012 and May 2015 Notes was $10.2 million for the year ended December 31, 2012. For the year ended December 31, 2012, compared to December 31, 2011 Non-operating expense, net, decreased primarily due to lower interest expense as a result of our quarterly repayment of the principal balance of our Non-recourse Notes and increased interest income from our Notes Receivable, offset, in part, by increased interest expense on our Series 2012 Notes and our May 2015 Notes. The increase in interest expense consisted primarily of non-cash interest expense as we were required to compute interest expense using the interest rate for similar nonconvertible instruments in accordance with the accounting guidance for convertible debt instruments that may be settled in cash or other assets on conversion. Non-cash interest expense, in accordance with the accounting guidance, for the Series 2012 Notes and May 2015 Notes was $10.2 million for the year ended December 31, 2012 , and for the May 2015 Notes, February 2015 Notes and 2012 Notes was $3.9 million for the year ended December 31, 2011. Income Taxes Income tax expense for the year ended December 31, 2013, was $137.3 million, which resulted primarily from applying the federal statutory income tax rate to income before income taxes. Income tax expense for the year ended December 31, 2012, was $115.5 million, which resulted primarily from applying the federal statutory income tax rate to income before income taxes. Income tax expense for the year ended December 31, 2011, was $108.0 million, which resulted primarily from applying the federal statutory income tax rate to income before income taxes and adjusting for a portion of the loss on the retirement or conversion of our 2023 Notes that was not tax deductible. During the year ended December 31, 2013, as a result of the evaluation of our uncertain tax positions, we increased the unrecognized tax benefits by $5.5 million primarily related to state items and decreased the unrecognized tax benefits by $5.7 million due to expiration of statute of limitations for our tax attributes. The Company expects its unrecognized tax benefits to decrease by $6.5 million due to the expiration of statute of limitations within the next twelve months, of which $6.5 million would affect the effective tax rate. During the year ended December 31, 2012, we recorded no change in our liability associated with uncertain tax positions. The future impact of the unrecognized tax benefits of $32.4 million, if recognized, comprises $9.3 million which would affect the effective tax rate and $23.1 million which would result in adjustments to deferred tax assets and corresponding adjustments to the valuation allowance. Estimated interest and penalties associated with unrecognized tax benefits increased our income tax expense in the Consolidated Statements of Income by $0.7 million during the year ended December 31, 2013, increased income tax expense by $0.2 million during the year ended December 31, 2012, and increased income tax expense by $0.5 million during the year ended December 31, 2011. 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, except as noted above, we do not anticipate any material change to the amount of our unrecognized tax benefit over the next twelve months. As of December 31, 2013, we had net deferred tax assets in excess of our deferred tax liabilities of approximately $7.1 million. We recorded a valuation allowance to reduce our deferred tax assets to amounts that are more likely than not to be realized. As of December 31, 2013, we had a valuation allowance of $5.4 million, primarily related to net operating loss carry forwards and research and development tax credits. Net Income per Share Net income per share for the years ended December 31, 2013, 2012 and 2011, is presented below: Net income per basic share ........................................................................... $ Net income per diluted share........................................................................ $ 1.89 1.66 $ $ 1.52 1.45 $ $ 1.43 1.15 Year Ended December 31, 2012 2011 2013 44 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 full-time employees managing our intellectual property, our asset acquisitions and other corporate activities as well as providing for certain essential reporting and management functions of a public company. We had cash, cash equivalents and investments in the aggregate of $99.5 million and $148.7 million, excluding restricted investments, at December 31, 2013 and 2012, respectively. The decrease was primarily attributable to the purchase of the Depomed intangible asset of $241.3 million, cash advanced on notes receivable of $148.7 million, payment of dividends of $84.0 million, offset in part by net cash provided by operating activities of $270.9 million and repayment of notes receivable of $58.1 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 our Queen et al. patents beyond the first quarter of 2016. We continuously evaluate alternatives to increase return for our stockholders by, for example, acquiring income generating assets, buying back our convertible notes, repurchasing our common stock, selling the Company and paying dividends. On January 29, 2014, 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 2014 to stockholders of record on March 5, June 5, September 5 and December 5 of 2014, 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 million two-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 year ended December 31, 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 45 addition, PDL to receive quarterly royalty payments based on a low double digit royalty rate of Wellstat Diagnostics' net revenues upon successful commercialization. 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, if any, of an affiliated 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 of the note receivable which 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 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. 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. At December 31, 2013, and 2012, the carrying value of the note was included in non-current assets. As of December 31, 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 direct the activities of Wellstat Diagnostics that most significantly impacts Wellstat Diagnostics's economic performance and is not the primary beneficiary of Wellstat Diagnostics; therefore, Wellstat Diagnostics is not subject to consolidation. As of December 31, 2013, the carrying value of all amounts advanced to Wellstat Diagnostics was $47.7 million, which was recorded in notes receivable. As of December 31, 2013, the maximum loss exposure was $47.7 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 December 31, 2013. 46 AxoGen 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 (assigned interests). 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 $2.5 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 assigned interests 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 with a third party. 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 assigned interests 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 $1.1 million and $0.6 million as of December 31, 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 $0.5 million related to the change in the estimated fair value of embedded derivative during the year ended December 31, 2013. 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 consolidated balance sheet. As of December 31, 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 (loss). 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 47 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. 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. 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). Within 9 months after the occurrence of the tranche two milestone, Durata may request up to a single additional $30 million borrowing. Until the occurrence of the tranche two milestone, outstanding borrowings under tranche one bear interest at the rate of 14.0% per annum, payable quarterly in arrears. Upon occurrence of the tranche two milestone, the interest rate of the loans will decrease to 12.75%. Principal repayment will commence on the fifth interest payment date, March 31, 2015. The principal amount outstanding will be repaid quarterly over the remainder of the loans in an increasing percentage of the principal outstanding at commencement of repayment. The loans will mature on October 31, 2018. Durata may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans. The Company is entitled to receive a fee in addition to the prepayment penalty in the event that Durata undergoes a change in control. The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Durata. Direct Flow Credit Agreement 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 (tranche one), 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 tranche two milestone), the Company will loan to Direct Flow Medical an additional $15.0 million, net of fees. Until the occurrence of the tranche two milestone, outstanding borrowings under tranche one bear interest at the rate of 15.5% per annum, payable quarterly in arrears. Upon occurrence of the tranche two milestone, the interest rate of the loans will decrease to 13.5%. Principal repayment will commence on the twelfth interest payment date, September 30, 2016. The principal amount outstanding at commencement of repayment will be repaid in equal installments until final maturity of the loans. The loans will mature on November 5, 2018. Direct Flow Medical may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans. The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Direct Flow Medical and any of its subsidiaries. 48 Intangible Assets 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. The royalty agreement terminates on the third anniversary following the date upon which the later of the following occurs: (a) October 25, 2021, or (b) at such time as no royalty payments remain payable under any license agreement and each of the license agreements has expired by its terms. Convertible Notes Series 2012 Notes We have actively worked to restructure the Company’s capital and reduce the potential dilution associated with our convertible notes. As part of those efforts, in January 2012, we exchanged and subsequently retired $169.0 million aggregate principal amount of our February 2015 Notes for an identical principal amount of our 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 exchanged and subsequently 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 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 is due in cash, and to the extent that the conversion value exceeds the principal amount, the difference is due in shares of our common stock. The effect of issuing $179.0 million aggregate principal of our Series 2012 Notes with the net share settle feature in exchange for our February 2015 Notes was the reduction of 27.8 million shares of potential dilution to our stockholders at the time of the exchange. On February 5 and 6, 2014, the Company entered into separate, privately negotiated exchange and purchase agreements under which it retired $131.7 million in aggregate principal of the Company’s outstanding Series 2012 Notes. The exchange agreements provided for the issuance, by the Company, of shares of common stock and a cash payment for the Series 2012 Notes being exchanged, and the purchase agreement provided for a cash payment for the Series 2012 Notes being repurchased. The Company issued a total of 20.3 million shares of its common stock and paid an aggregate cash payment of $34.2 million pursuant to the exchange and repurchase agreements. 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. 49 February 2018 Notes On February 6, 2014, the Company agreed to sell $260.87 million aggregate principal amount of its 4.00% Convertible Senior Notes due February 1, 2018, in an underwritten public offering. The conversion rate of the February 2018 Notes will initially be 109.1048 shares of common stock per $1,000 principal amount of the February 2018 Notes equivalent to an initial conversion price of approximately $9.17 per share of common stock. The conversion rate, subject to increase under certain circumstances, will not be increased in respect of regular quarterly cash dividends paid by us that do not exceed $0.15 per share. On February 12, 2014, the Company issued $300 million aggregate principal amount of February 2018 Notes, which included $39.13 million aggregate principal amount of February 2018 Notes issued pursuant to the exercise of the underwriters’ overallotment option to purchase additional February 2018 Notes. In connection with the offering of the February 2018 Notes, we entered into privately negotiated convertible note hedge transactions with affiliates of RBC Capital Markets and Well Fargo Securities (“hedge counterparties”) and privately negotiated warrant transactions with the hedge counterparties relating to the same number of shares of PDL’s common stock. Off-Balance Sheet Arrangements As of December 31, 2013, we did not have any off-balance sheet arrangements, as defined under SEC Regulation S-K Item 303 (a)(4)(ii). Contractual Obligations Convertible Notes As of December 31, 2013, our contractual obligations consisted primarily of our Series 2012 Notes and our 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. See Note 21 for subsequent event transactions related to convertible notes. Term Loan As of December 31, 2013, our contractual obligation for our term loan total $75.0 million in principal. 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. 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. 50 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 of Facet, 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. In April 2010, Abbott acquired Facet and later renamed the entity AbbVie Biotherapeutics, Inc. As of December 31, 2013, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately $90.2 million, and has not been included in the table above. If AbbVie 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 Consolidated Balance Sheets as of December 31, 2013 and 2012, related to this guarantee. Indemnification As permitted under Delaware law, 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. 51 ITEM 7A. 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 is 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, and in 2011, Euro forward and option contracts. In general, these contracts are intended to offset the underlying Euro market risk in our royalty revenues. 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 $391,000 in interest and other income, net. The termination of these contracts was effected through a reduction in the notional amount of the original hedge contracts that was then exchanged for new hedges of 2014 Euro-denominated royalties. These 2014 hedges were entered into at a rate more favorable than the market rate as of the date of the exchange. Gains or losses on our cash flow hedges are recognized in the same period that the hedged transaction impacts earnings as an adjustment to royalty revenue. Ineffectiveness, if any, resulting from the change in fair value of the modified 2012 hedge or lower than forecasted Euro-based royalties will be reclassified from other comprehensive income (loss) and recorded as interest and other income, net, in the period it occurs. The following table summarizes the notional amounts, Euro exchange rates and fair values of our outstanding Euro contracts designated as hedges at December 31, 2013 and 2012: Euro Forward Contracts Settlement Price ($ per Euro) 1.230 1.240 1.270 1.281 1.300 Type Sell Euro Sell Euro Sell Euro Sell Euro Sell Euro Currency Euro .....................

If market 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 $490.0 million at December 31, 2013, and $410.5 million at December 31, 2012, based on available pricing information. At December 31, 2013, 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%. At December 31, 2012, our convertible notes consisted of our Series 2012 Notes, with a fixed interest rate of 2.875%, May 2015 Notes, with a fixed interest rate of 3.75% and our February 2015 Notes, with a fixed interest rate of 2.875%. These obligations are subject to interest rate risk because the fixed interest rates under these obligations may exceed current interest rates. The fair value of our term loan was estimated to be $75.0 million at December 31, 2013, based on available pricing information. No amounts were outstanding under the term loan at December 31, 2012. 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. These obligations are subject to interest rate risk because the variable interest rate may increase in future periods. The following table presents information about our material debt obligations that are sensitive to changes in interest rates. The table presents principal amounts and related weighted-average interest rates by year of expected maturity for our debt obligations or the earliest year in which the holders may put the debt to us.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS December 31, 2013 1. Organization and Business 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, acquiring 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 continues to pursue this strategic initiative for which it has already invested approximately $500 million to date. PDL is focused on the quality of the income generating assets and potential returns on investment. In the year ended December 31, 2013, we received Queen et al. patent 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 Genentech................................................................................... Avastin® Product Names 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. We have also entered into licensing agreements under which we have licensed certain rights under our patents for development- stage products that have not yet reached commercialization including products that are currently in Phase 3 clinical trials. Until December 2008, our business included biotechnology operations which were focused on the discovery and development of novel antibodies which we spun off to Facet Biotech Corporation. In April 2010, Abbott Laboratories acquired Facet and later renamed the company Abbott Biotherapeutics Corp., and in January 2013, Abbott Biotherapeutics, Corp. was renamed AbbVie Biotherapeutics, Inc. and spun off from Abbott as a subsidiary of AbbVie Inc. 60 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles and under the rules and regulations of the Securities and Exchange Commission. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, QHP Royalty Sub LLC. All material intercompany balances and transactions are eliminated in consolidation. Management Estimates The preparation of financial statements in conformity with GAAP requires the use of management’s estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Segment Disclosures Our chief operating decision-maker consists of our executive management. Our chief operating decision-maker reviews our operating results and operating plans and makes resource allocation decisions on a company-wide basis; therefore, we operate as one segment. Cash Equivalents and Investments We consider all highly liquid investments with initial maturities of three months or less at the date of purchase to be cash equivalents. We place our cash and cash equivalents with high credit quality financial institutions and, by policy, limit the amount of credit exposure in any one financial instrument. Available-for-sale securities are reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive income (loss). See Note 5. 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 we paid to transfer a liability in an orderly transaction between market participants at the measurement date or exit price. The assets and liabilities are categorized and disclosed in one of the following three categories: Level 1 – based on quoted market prices in active markets for identical assets and liabilities; Level 2 – based on quoted market prices for similar assets and liabilities, using observable market based inputs or unobservable market based inputs corroborated by market data, and Level 3 – based on unobservable inputs using management’s best estimate and assumptions when inputs are unavailable. We do not estimate the fair value of our royalty assets for financial statement reporting purposes. Notes and Other Long-Term Receivables Notes receivable and loans originated by us are initially recorded at the amount advanced to the borrower. Notes receivable and loan origination and commitment fees, net of certain origination costs, are recorded as an adjustment to the carrying value of the notes receivable and loans and are amortized over the term of the related financial asset using the effective interest rate method. Certain of our notes receivable and loans require the borrower to make variable payments which are dependent upon the borrower's sales of specific products. We have elected to use the prospective interest method to account for these notes receivable and loans subsequent to their initial recognition. Under this approach, we recognize the impact of any variations from the expected returns in the period when received. From time to time, we will re-evaluate the expected cash flows and may adjust the effective interest rate with effect prospective from the date of assessment, if the impact of such adjustment could be material to our financial statements. Determining the initial effective interest rates and subsequent re-assessment of the effective interest rates 61 for notes receivable and loans with variable cash flows requires judgment and is based on significant assumptions related to estimates of the amounts and timing of future product sales by the borrowers. We evaluate the collectability of both interest and principal for each note receivable and loan to determine whether it is impaired. A note receivable or loan is considered to be impaired when, based on current information and events, we determine it is probable that we will be unable to collect all amounts due according to the existing contractual terms. When a note receivable or loan is considered to be impaired, the amount of loss is calculated by comparing the carrying value of the financial asset to the value determined by discounting the expected future cash flows at the loan's effective interest rate or to the estimated fair value of the underlying collateral, less costs to sell, if the loan is collateralized and we expect repayment to be provided solely by the collateral. Impairment assessments require significant judgments and are based on significant assumptions related to the borrower's credit risk, financial performance, expected sales, and fair value of the collateral. Intangible Assets Amortization of definite-lived intangible royalty assets is computed using a units of production method over the estimated useful lives of the assets. The related amortization is recognized as a cost of royalty revenues. Identifiable intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. If the fair value is less than the carrying amount of the asset, a loss is recognized for the difference. Foreign Currency Hedging We enter into foreign currency hedges to manage exposures arising in the normal course of business and not for speculative purposes. We hedge certain Euro-denominated currency exposures related to our licensees’ product sales with Euro forward contracts. In general, these contracts are intended to offset the underlying Euro market risk in our royalty revenues. These contracts extend through the fourth quarter of 2014. We designate foreign currency exchange contracts used to hedge royalty revenues based on underlying Euro-denominated sales as cash flow hedges. At the inception of the hedging relationship and on a quarterly basis, we assess hedge effectiveness. The fair value of the Euro 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 portions is reported in other income in the period the ineffectiveness occurs. During the third quarter of 2012, we de-designated and terminated a portion of our cash flow hedges. The gain realized was reclassified from other comprehensive income (loss) to other income in the third quarter. See Note 6 for additional information on our foreign currency hedge transactions. Revenue Recognition Licensed Royalty Revenues Under most of our patent license agreements, we receive royalty payments based upon our licensees’ net sales of covered products. Generally, under these agreements we receive royalty reports from our licensees approximately one quarter in arrears, that is, generally in the second month of the quarter after the licensee has sold the royalty-bearing product. We recognize royalty revenues when we can reliably estimate such amounts and collectability is reasonably assured. As such, we generally recognize royalty revenues in the quarter reported to us by our licensees, that is, royalty revenues are generally recognized one quarter following the quarter in which sales by our licensees occurred. Under this accounting policy, the royalty revenues we report are not based upon our estimates and such royalty revenues are typically reported in the same period in which we receive payment from our licensees. We may also receive annual maintenance fees from licensees of our Queen et al. patents prior to patent expiry as well as periodic milestone payments. We have no performance obligations with respect to such fees. Maintenance fees are recognized as they are due and when payment is reasonably assured. Total annual milestone payments in each of the last several years have been less than 1% of total revenue. 62 Acquired Royalty Revenues We receive royalty payments based upon Depomed's licensees’ net sales of covered products. Generally, under these agreement we receive royalty reports from Depomed approximately one month in arrears, that is, generally in the month after Depomed's licensee has sold the royalty-bearing product. We recognize royalty revenues when we can reliably estimate such amounts and collectability is reasonably assured. As such, we generally recognize royalty revenues in the month reported to us by Depomed, that is, royalty revenues are generally recognized one month following the month in which sales by Depomed's licensees occurred. Under this accounting policy, the royalty revenues we report are not based upon our estimates and such royalty revenues are typically reported in the same period in which we receive payment from Depomed licensees. Comprehensive Income (Loss) Comprehensive income (loss) comprises net income adjusted for other comprehensive income (loss), using the specific identification method, which includes the changes in unrealized gains and losses on cash flow hedges and changes in unrealized gains and losses on our investments in available-for-sale securities, all net of tax, which are excluded from our net income. Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization were computed using the straight-line method over the following estimated useful lives: Leasehold improvements............................................................ Shorter of asset life or term of lease Computer and office equipment .................................................

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 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 63 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 include the shares issuable in respect of such excess. We excluded from our calculations of net income per diluted share 21.1 million and 19.6 million shares for the years ended December 31, 2013 and 2012, respectively, for our warrants issued in 2011, because the exercise price of the warrants exceeded the average market price of our common stock and thus, for the periods presented, no stock was issuable upon conversion. These securities could be dilutive in future periods. Our purchased call options, issued in 2011, will always be anti-dilutive and therefore 24.8 million and 23.0 million shares were excluded from our calculations of net income per diluted share for the years ended December 31, 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 13. For the years ended December 31, 2013, 2012 and 2011, we excluded approximately 115,000, 157,000 and 193,000 shares, respectively, underlying outstanding stock options, and for the years ended December 31, 2013, 2012 and 2011, we excluded approximately zero, 1,000, and zero shares, respectively, underlying restricted stock awards, calculated on a weighted average basis, from our net income per diluted share calculations because their effect was anti-dilutive. 4. 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 following table presents the fair value of our financial instruments measured at fair value on a recurring basis by level of input within the fair value hierarchy defined in Note 2: (In thousands) Assets: December 31, 2013 Level 2 Level 1 Total Level 1 December 31, 2012 Level 2 Total Money market funds ..........................

At December 31, 2012, the certificates of deposit include a $20 million certificate of deposit that was restricted as it was purchased to collateralize the line of credit for Merus Labs; see Note 7. 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 is estimated using recently executed transactions or market quoted prices, where observable. Independent pricing sources are also used for valuation. The fair value of the foreign currency hedging contracts is estimated based on pricing models using readily observable inputs from actively quoted markets and are disclosed on a gross basis. 64 There have been no transfers between levels during the years ended December 31, 2013 and 2012. The Company recognizes transfers between levels on the date of the event or change in circumstances that caused the transfer.

In some instances the carrying values of certain notes receivable exceed their estimated fair market values. This is generally the result of discount rates used when performing a discounted cash flow for fair value valuation purposes. In all cases, the undiscounted expected future cash flows exceed the related carrying value. When deemed necessary we engage a third party valuation expert to evaluate our investments and the related inputs needed for us to estimate the fair value of certain investments. We determined our notes receivable of our assets to be Level 3 assets as our valuations utilized significant unobservable inputs, including estimates of future revenues, discount rates, expectations about settlement, terminal values and required yield. To provide support for the estimated fair value measurements, we considered forward looking performance related to the investment 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 similar sectors. The carrying value and estimated fair value of the AxoGen note receivable include the value of a change of control embedded derivative valued at $1.1 million and $0.6 million at December 31, 2013 and 2012, respectively. We utilized discounted cash flows and probability analysis to estimate the fair value of the embedded derivative. On December 31, 2013, the estimated fair value of Wellstat was determined by using a discounted cash flow that was based upon expected income from estimated sales through December 31, 2016. Due to breach of the credit agreement as of December 31, 2012, as discussed in Note 7, we considered the estimated fair value of the collateral when estimating fair value of the note. The note is collateralized by all assets and equity interest in Wellstat Diagnostics. The estimated 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 period of 15 years. The terminal value was estimated using selected market multiples based on sales and EBITDA. 65 — — 5,238 5,238 — — 3,905 13,572 The fair values of our convertible notes were determined using quoted market pricing or dealer quotes. 5. Cash, Cash Equivalents and Investments As of December 31, 2013, we had invested our excess cash balances primarily in money market funds, certificates of deposit, and a corporate security, and in 2012, money market funds, certificates of deposit, 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. See Note 4 for fair value measurement information. The cost of securities sold is based on the specific identification method. To date, we have not experienced credit losses on investments in these instruments and we do not require collateral for our investment activities.

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 Consolidated Balance Sheets as we have entered into a netting arrangement with the counterparty. As of December 31, 2013 and 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 2014. 66 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 not probable to 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, fair values of our Euro forward contracts designated as cash flow hedges were as follows: Euro Forward Contracts Currency Euro .....................

Notes and Other Long-term Receivables Notes 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 million two-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). The full amount available under this agreement was drawn by Wellstat Diagnostics in November 2012. 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 year ended December 31, 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 receive quarterly royalty payments based on a low double digit royalty rate of Wellstat Diagnostics' net revenues upon successful commercialization. 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, if any, of an affiliated 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 of the note receivable which 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 68 threshold in 2017, Wellstat Diagnostics will be required to 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. 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. At December 31, 2013, and 2012, the carrying value of the note was included in non-current assets. As of December 31, 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 direct the activities of Wellstat Diagnostics that most significantly impacts Wellstat Diagnostics's economic performance and is not the primary beneficiary of Wellstat Diagnostics; therefore, Wellstat Diagnostics is not subject to consolidation. As of December 31, 2013, the carrying value of all amounts advanced to Wellstat Diagnostics was $47.7 million, which was recorded in notes receivable. As of December 31, 2013, the maximum loss exposure was $47.7 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 December 31, 2013. AxoGen 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 (assigned interests). 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 $2.5 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 assigned interests 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 with a third party. 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 assigned interests 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 69 and separately recorded at its estimated fair value. The estimated fair value of the change of control provision was approximately $1.1 million and $0.6 million as of December 31, 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 $0.5 million related to the change in the estimated fair value of embedded derivative during the year ended December 31, 2013. 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 consolidated balance sheet. As of December 31, 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 (loss). 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. 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. 70 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). Within 9 months after the occurrence of the tranche two milestone, Durata may request up to a single additional $30 million borrowing. Until the occurrence of the tranche two milestone, outstanding borrowings under tranche one bear interest at the rate of 14.0% per annum, payable quarterly in arrears. Upon occurrence of the tranche two milestone, the interest rate of the loans will decrease to 12.75%. Principal repayment will commence on the fifth interest payment date, March 31, 2015. The principal amount outstanding will be repaid quarterly over the remainder of the loans in an increasing percentage of the principal outstanding at commencement of repayment. The loans will mature on October 31, 2018. Durata may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans. The Company is entitled to receive a fee in addition to the prepayment penalty in the event that Durata undergoes a change in control. The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Durata. Direct Flow Credit Agreement 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 (tranche one), 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 tranche two milestone), the Company will loan to Direct Flow Medical an additional $15.0 million, net of fees. Until the occurrence of the tranche two milestone, outstanding borrowings under tranche one bear interest at the rate of 15.5% per annum, payable quarterly in arrears. Upon occurrence of the tranche two milestone, the interest rate of the loans will decrease to 13.5%. Principal repayment will commence on the twelfth interest payment date, September 30, 2016. The principal amount outstanding at commencement of repayment will be repaid in equal installments until final maturity of the loans. The loans will mature on November 5, 2018. Direct Flow Medical may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans.

Intangible Assets 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 payable on sales of Type 2 diabetes products licensed by Depomed in exchange for a $240.5 million cash payment. Total arrangement consideration was $241.3 million which was comprised of the $240.5 million cash payment to Depomed and $0.8 million in transaction costs. The rights acquired include Depomed’s royalty and milestone payments accruing from and after October 1, 2013: (a) from Santarus with respect to sales of Glumetza® (metformin HCL extended-release tablets) in the United States; (b) from Merck with respect to sales of Janumet® XR (sitagliptin and metformin HCL extended-release); (c) from Janssen Pharmaceutica with respect to potential future development milestones and sales of its investigational fixed-dose combination of Invokana® (canagliflozin) and extended-release metformin; (d) from Boehringer Ingelheim with respect to potential future development milestones and sales of the investigational fixed-dose combinations of drugs and extended-release metformin subject to Depomed’s license agreement with Boehringer Ingelheim; and (e) from LG Life Sciences and Valeant Pharmaceuticals for sales of extended-release metformin in Korea and Canada, respectively. 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 it made to Depomed, after which all net payments received by Depomed will be shared evenly between the Company and Depomed. The royalty agreement terminates on the third anniversary following the date upon which the later of the following occurs: (a) October 25, 2021, or (b) at such time as no royalty payments remain payable under any license agreement and each of the license agreements has expired by its terms. This transaction has been accounted for as the acquisition of intangible assets. An income approach was used for the purpose of allocating the purchase price based on the relative fair value of each intangible asset and in the determination of the useful life of each intangible asset. The intangible assets have finite lives ranging from three to nine years and will be amortized to cost of royalty revenues over the related periods. During the fourth quarter of 2013, we began receiving royalty revenues related to Glumetza and commenced amortization of the carrying value of the related intangible asset of $164.5 million. The intangible assets related to the other licensed products with a carrying value of $76.8 million were not being amortized as of December 31, 2013 as no revenues were recognized related to those intangible assets in 2013. We will commence amortization of those intangible assets when the Company receives royalty revenues related to sales of the related products. The fair value of the intangible assets acquired was determined by using a discounted cash flow analysis related to the expected future cash flows to be generated by each licensed product. The discounted cash flow was based upon expected royalties from sales of licensed products over periods up to nine years. We determined that the intangible assets were Level 3 assets, as our valuation utilized significant unobservable inputs, including estimates as to the probability and timing of future commercialization for products not yet approved by the FDA or other regulatory agencies. 72 As of December 31, 2013, the carrying value of the intangible assets acquired in our consolidated balance sheet was approximately $235.7 million. As of December 31, 2013, the maximum loss exposure was $235.7 million. The following table summarizes the components of gross and net intangible assets balances as of December 31, 2013: (in thousands) Definite lived intangible assets .....

However, the Company does not have the power to direct the activities of Depo DR Sub, LLC that most significantly impacts the Depo DR Sub, LLC's economic performance and is not the primary beneficiary of Depo DR Sub, LLC therefore, it is not subject to consolidation by the Company. 11.

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 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% 74 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 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’ equity (deficit).

As of December 31, 2013, the remaining discount amortization period was 1.1 years. Our common stock 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 were convertible at the option of the holder during the quarter ended December 31, 2013. Our common stock price exceeded the conversion threshold price of $7.12 per common share for at least 20 days during the 30 consecutive trading days ended December 31, 2013; accordingly, the Series 2012 Notes are convertible at the option of the holder during the quarter ending March 31, 2014. The Series 2012 Notes have been classified as current as the notes will be due upon demand within one year of the year ended December 31, 2013. At December 31, 2013, the if-converted value of our Series 2012 Notes exceeded their principal amount by approximately $97.4 million. See Note 21 for subsequent event transactions related to convertible notes. 75 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.

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%.

Our common stock price did exceed the conversion threshold price of $8.13 per common share for at least 20 days during the 30 consecutive trading days ended December 31, 2013; accordingly, the May 2015 Notes are convertible at the option of the holder during the quarter ending March 31, 2014. The May 2015 Notes have been classified as current as the notes will be due upon demand within one year of the year ended December 31, 2013. At December 31, 2013, the if-converted value of our May 2015 exceeded their principal amount by approximately $54.3 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 24.8 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 $6.25 and $7.50, subject to further adjustment upon certain events including dividend payments, for the purchased call options and warrants, respectively. If the share price is above $6.25, but below $7.50, 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 $7.50, 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 $7.50. For example, a 10% increase in the share price above $7.50 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 December 31, 2013, and 2012, 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 December 31, 2013, and 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 77 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. Non-recourse Notes Retirement In November 2009, we completed a $300.0 million securitization transaction in which we monetized 60% of the net present value of the estimated 5 years royalties from sales of Genentech products including Avastin®, Herceptin®, Lucentis®, Xolair® and future products, if any, under which Genentech may take a license under our related agreements with Genentech. Our QHP PhaRMASM Senior Secured Notes due 2015 bore interest at 10.25% per annum and were issued in a non-registered offering by QHP, a Delaware limited liability company, and a newly formed, wholly-owned subsidiary of PDL. Concurrent with the securitization transaction and under the terms of a purchase and sale agreement, we sold, transferred, conveyed, assigned, contributed and granted to QHP, certain rights under our non-exclusive license agreements with Genentech including the right to receive the Genentech Royalties in exchange for QHP’s proceeds from our Non-recourse Notes issuance. As of December 31, 2012, there was no remaining balance on our Non-recourse Notes, as they were fully repaid and retired on September 17, 2012. The indenture has ceased to be of further effect and all of the security interests in the collateral have terminated, including the pledge by PDL to the trustee of its equity interest in QHP. There are no further restrictions on the Genentech Royalties. Term Loan On October 28, 2013, PDL entered into a credit agreement among the Company, the lenders party, and Royal Bank of Canada as administrative agent. The initial Term Loan amount was for $75 million, with a term of one year. 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. As of December 31, 2013, the interest rate was 2.24%. Interest and principal payments associated with the Term Loan 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 Term Loan, except as otherwise provided. The Company’s obligations under the Term Loan are secured by a lien on a substantial portion of its assets. The Term Loan contains affirmative and negative covenants that the Company believes are usual and customary for a senior secured credit agreement. The Term loan 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 Term Loan and compliance with which may be necessary to take certain corporate actions. The Term Loan contains events of default that the Company believes are usual and customary for a senior secured credit agreement. As of December 31, 2013 and 2012, PDL was in compliance with all applicable debt covenants. As of December 31, 2013, the future minimum principal payments under our Series 2012 Notes, May 2015 Notes and Term Loan were: (In thousands) 2014.......................................................... 2015..........................................................

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 December 31, 2013, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately $90.2 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 December 31, 2013, and 2012, related to this guarantee. 15. Stock-Based Compensation We recognize compensation expense using a fair-value based method for costs associated with all share-based awards issued to our directors, employees and outside consultants under our stock plan. The value of the portion of the award that is ultimately expected to vest is recognized as expense on a straight-line basis over the requisite service periods in our Consolidated Statements of Income. We have adopted the simplified method to calculate the beginning balance of the additional paid-in capital pool of the excess tax benefit and to determine the subsequent effect on the APIC pool and Consolidated Statements of Cash Flows of the tax effects of employee stock-based compensation awards that were outstanding upon our adoption. We calculate stock-based compensation expense based on the number of awards ultimately expected to vest, net of estimated forfeitures. We estimate forfeiture rates at the time of grant and revise such rates, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The stock-based compensation expense was determined using the Black-Scholes option valuation model. Stock-based compensation expense for employees and directors and non-employees for the years ended December 31, 2013, 2012 and 2011, is presented below: Year Ended December 31, Stock-based Compensation 2013 2012 2011 (In thousands) Employees and directors .....................

(2) Plan terminated in 2009, subject to options outstanding under the plan. Under our 2005 Equity Incentive Plan, we are authorized to issue a variety of incentive awards, including stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance share and performance unit awards, deferred compensation awards and other stock-based or cash-based awards. In 2009, our Compensation Committee terminated the 1991 Nonstatutory Stock Option Plan. Additionally our Compensation Committee terminated the 1999 Outside Director Stock Option Plan, the 1999 Nonstatutory Stock Option Plan and the 2002 Outside Directors Stock Option Plan, subject to any outstanding options. Also in June 2009, our stockholders approved amendments to the Company’s 2005 Equity Incentive Plan to expand persons eligible to participate in the plan to include our outside directors.

The aggregate intrinsic value represents the total pre-tax intrinsic value, based on the closing prices of our common stock of $8.44 on December 31, 2013, which would have been received by the option holders had option holders exercised their options as of that date. All stock options were fully vested as of 2010 and at December 31, 2013, had a range of exercise price of $5.41 to $22.60. Restricted Stock Restricted stock has the same rights as other issued and outstanding shares of the Company’s common stock, including, in some cases, the right to accrue dividends, which are held in escrow until the award vests. The compensation expense related to these awards is determined using the fair market value of the Company’s common stock on the date of the grant, and the compensation expense is recognized ratably over the vesting period. Restricted stock awards typically vest over twelve to twenty-four months. In addition to service requirements, vesting of restricted stock awards may be subject to the achievement of specified performance goals set by the Compensation Committee of the Company’s Board of Directors. If the performance goals are not met, no compensation expense is recognized and any previously recognized compensation expense is reversed. 80 A summary of our restricted stock activity is presented below: 2013 2012 2011 Number of shares (in thousands) Weighted- average grant-date fair value per share Number of shares (in thousands) Weighted- average grant-date fair value per share Number of shares (in thousands) Weighted- average grant-date fair value per share Nonvested at beginning of year ............

As of December 31, 2013, the aggregate intrinsic value of non- vested restricted stock was $1.0 million. Total unrecognized compensation costs associated with non-vested restricted stock as of December 31, 2013, was $0.4 million, excluding forfeitures, which we expect to recognize over a weighted-average period of 10 months. 16. Cash Dividends On January 29, 2014, our board of directors declared that the regular quarterly dividends to be paid to our stockholders in 2014 will be $0.15 per share of common stock, payable on March 12, June 12, September 12 and December 12 of 2014 to stockholders of record on March 5, June 5, September 5 and December 5 of 2014, the record dates for each of the dividend payments, respectively. On January 23, 2013, our board of directors declared a regular quarterly dividend of $0.15 per share of common stock, which were paid 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. We paid $84.0 million in dividends in 2013. On January 18, 2012, our board of directors declared regular quarterly dividends of $0.15 per share of common stock, which were paid on March 14, June 14, September 14 and December 14 of 2012 to stockholders of record on March 7, June 7, September 7 and December 7 of 2012, the record dates for each of the dividend payments, respectively. We paid $83.9 million in dividends in 2012. On February 25, 2011, our board of directors declared regular quarterly dividends of $0.15 per share of common stock, which were paid on March 15, June 15, September 15 and December 15 of 2011 to stockholders of record on March 8, June 8, September 8 and December 8 of 2011, the record dates for each of the dividend payment dates, respectively.

We also had California net operating loss carryforwards of $215.5 million as of December 31, 2013 and 2012. The federal net operating loss carryforwards will expire in the year 2023 and the California net operating loss carryforwards will expire between 2014 and 2019, if not utilized. As of December 31, 2013 and 2012, we had $20.0 million of state tax credit carryforwards that do not expire and can be carried forward indefinitely. The net operating loss carryforwards and tax credit carryforwards which resulted from exercises of stock options were not recorded on the Consolidated Balance Sheet. Utilization of the federal and state net operating loss and tax credit carryforwards may be subject to a substantial annual limitation due to the "change in ownership" provisions of the Internal Revenue Code of 1986. The annual limitation may result in the expiration of net operating losses and credits before utilization. We have an annual limitation on the utilization of our federal operating losses of $1.8 million for each of the years ending December 31, 2014 to 2022, and $1.3 million for the year ending December 31, 2023. As of December 31, 2013, we estimate that at least $22.0 million of the $39.4 million of federal net operating loss carryforwards and $18.7 million of the $215.5 million state net operating losses will expire unutilized. During 2013, as a result of changes in our business model and increased forecasted earnings, we determined that it was more likely than not that certain net operating losses, tax credits and other deferred tax assets would be realized in the near future. As a result, our valuation allowance against deferred tax assets was decreased by $15 million. We continue to believe it is more likely than not that the benefit from certain net operating losses and deferred tax assets will not be realized in the near future, and have provided a valuation allowance of $5.4 million against these deferred tax assets. 83 A reconciliation of our unrecognized tax benefits, excluding accrued interest and penalties, for 2013, 2012 and 2011 is: (In thousands) Balance at the beginning of the year .................................................................

We periodically evaluate our exposures associated with our tax filing positions. During 2013, as a result of the evaluation of our uncertain tax positions, we increased the unrecognized tax benefits by $5.5 million primarily related to state items and decreased the unrecognized tax benefits by $5.7 million due to expiration of statute of limitation for our tax attributes. The Company expects its unrecognized tax benefits to decrease by $6.5 million due to the expiration of statute of limitations within the next twelve months, substantially all of which would affect the effective income tax rate. Estimated interest and penalties associated with unrecognized tax benefits decreased income tax expense in the Consolidated Statements of Income by $0.7 million during the year ended December 31, 2013, and increased income tax expense by $0.2 million, and $0.5 million during the year ended December 31, 2012, and 2011, respectively. In general, our income tax returns are subject to examination by U.S. federal, state, and local tax authorities for tax years 1996 forward. Interest and penalties associated with unrecognized tax benefits accrued on the balance sheet were $1.5 million and $0.7 million as of December 31, 2013 and 2012, respectively. In May 2012, PDL received a “no-change” letter from the IRS upon completion of an examination of the Company's 2008 Federal tax return. We are currently under income tax examination in the state of California for tax years 2010, 2009 and 2008. 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, except as noted above, we do not anticipate any material change to the amount of our unrecognized tax benefits related to the California audit over the next twelve months. 19. 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 Consolidated Statements of Comprehensive Income. 84 The balance of accumulated other comprehensive income (loss), net of tax, was as follows: Unrealized gain (loss) on available-for- sale securities Unrealized gain (loss) on cash flow hedges Total Accumulated Other Comprehensive Income (Loss) (In thousands) Beginning Balance at December 31, 2010................................................

Legal Proceedings Resolution of Past Challenges to the Queen et al. Patents in the United States and Europe MedImmune Settlement On February 10, 2011, we entered into a definitive settlement agreement with MedImmune resolving all legal disputes with them, including those relating to MedImmune’s product Synagis® and PDL’s patents known as the Queen et al. patents. Under the settlement agreement, PDL paid MedImmune $65.0 million on February 15, 2011, and an additional $27.5 million on February 9, 2012, for a total of $92.5 million. No further payments will be owed by MedImmune to PDL under its license to the Queen et al. patents as a result of past or future Synagis sales and MedImmune will cease any support, financial or otherwise, of any party involved in the appeal proceeding before the European Patent Office relating to the opposition against our '216B Patent including the opposition owned by BioTransplant. Settlement with UCB On February 2, 2011, we reached a settlement with UCB. Under the settlement agreement, PDL provided UCB a covenant not to sue UCB for any royalties regarding UCB’s Cimzia® product under the Queen et al. patents in return for a lump sum payment of $10.0 million to PDL and termination of pending patent interference proceedings before the U.S. Patent and Trademark office involving our U.S. Patent No. 5,585,089 patent and our U.S. Patent No. 6,180,370 in PDL’s favor. UCB also agreed to formally withdraw its opposition appeal challenging the validity of the ‘216B Patent. Settlement with Novartis On February 25, 2011, we reached a settlement with Novartis. Under the settlement agreement, PDL agreed to dismiss its claims against Novartis in its action in Nevada state court which also includes Genentech and Roche as defendants. Novartis agreed to withdraw its opposition appeal in the EPO challenging the validity of the ‘216B Patent. Under the settlement agreement with Novartis, we will pay Novartis certain amounts based on net sales of Lucentis made by Novartis during calendar year 2011 and beyond. The settlement does not affect our claims against Genentech and Roche in the Nevada state court action. We do not currently expect such amount to materially impact our total annual revenues. European Opposition to ‘216B Patent Termination of European Opposition to ‘216B Patent Pursuant to our settlements with UCB, MedImmune and Novartis, and as a result of our acquisition of BioTransplant and subsequent withdrawal of BioTransplant’s appeal, all of the active appellants in the EPO opposition have formally withdrawn their participation in the appeal proceeding. Accordingly, the EPO has canceled the appeal proceeding and terminated the 85 opposition proceeding in its entirety, with the result that the 2007 EPO decision upholding the claims of our ‘216B Patent as valid will become the final decision of the EPO. In the year ending December 31, 2013, approximately 43% of our royalty revenues were derived from sales of products that were made in Europe and sold outside of the United States. Genentech / Roche Matter Settlement Agreement On January 31, 2014, we entered into a settlement agreement with Genentech and Roche which resolves all outstanding legal disputes between the parties, including our Nevada litigation with Genentech relating to an August 2010 facsimile sent by Genentech on behalf of Roche and Novartis asserting its products do not infringe on PDL’s SPC’s, and our arbitration proceedings with Genentech related to the audit of royalties on sales. Under the terms of the settlement agreement, effective retroactively to August 15, 2013, Genentech will pay a fixed royalty rate of 2.125 percent on worldwide sales of all its licensed products, as compared to the previous tiered royalty rate in the U.S and the fixed rate on all ex-U.S. based manufactured and sold licensed products. Pursuant to the agreement, Genentech and Roche confirmed that Avastin, Herceptin, Lucentis, Xolair and Perjeta are licensed products as defined in the relevant license agreements between the parties, and further agreed that Kadcyla and Gazyva are licensed products. Genentech will pay these royalties on all worldwide sales of Avastin, Herceptin, Xolair, Perjeta and Kadcyla occurring on or before December 31, 2015. With respect to Lucentis, Genentech owes no royalties on U.S. sales occurring after June 30, 2013, and will pay a royalty of 2.125 percent on all ex-U.S. sales occurring on or before December 28, 2014. The royalty term for Gazyva remains unchanged from the existing license agreement pertaining thereto. The agreement precludes Genentech and Roche from challenging the validity of PDL’s patents, including its SPCs in Europe, from contesting their obligation to pay royalties, from contesting patent coverage for Avastin, Herceptin, Lucentis, Xolair, Perjeta, Kadcyla and Gazyva and from assisting or encouraging any third party in challenging PDL’s patents and SPCs. The agreement further outlines the conduct of any audits initiated by PDL of the books and records of Genentech in an effort to ensure a full and fair audit procedure. Finally, the agreement clarifies that the sales amounts from which the royalties are calculated does not include certain taxes and discounts. The settlement and the related agreements are conditional upon entry of a proposed order dismissing the underlying litigation and dismissal of the AAA arbitration filed by PDL. Other Legal Proceedings In addition, from time to time, we may be 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. 21. Subsequent Events February 2018 Notes On February 6, 2014, the Company agreed to sell $260.87 million aggregate principal amount of its February 2018 Notes in an underwritten public offering. The conversion rate of the February 2018 Notes will initially be 109.1048 shares of common stock per $1,000 principal amount of the February 2018 Notes equivalent to an initial conversion price of approximately $9.17 per share of common stock. The Company granted the underwriters an option to purchase up to an additional $39.13 million aggregate principal amount of the February 2018 Notes solely to cover overallotments (or $300 million principal amount in the aggregate). The conversion rate, subject to increase under certain circumstances, will not be increased in respect of regular quarterly cash dividends paid by us that do not exceed $0.15 per share. On February 12, 2014, we issued $300 million aggregate principal amount of February 2018 Notes, which included $39.13 million aggregate principal amount of February 2018 Notes issued pursuant to the exercise of the underwriters’ overallotment option to purchase additional February 2018 Notes. In connection with the offering of the February 2018 Notes, the Company has entered into privately negotiated convertible note hedge transactions with RBC Capital Markets and Wells Fargo Securities. The convertible note hedge transactions will cover, subject to customary anti-dilution adjustments, the number of shares of the Company’s common stock that will initially 86 underlie the February 2018 Notes, and are intended to reduce the dilutive impact of the conversion feature of the February 2018 Notes on the Company’s outstanding shares of common stock. The Company has also entered into privately negotiated warrant transactions with the hedge counterparties relating to the same number of shares of the Company’s common stock. The warrant transactions could separately have a dilutive effect to the extent that the market price per share of the Company’s common stock exceeds the applicable strike price of the warrants on any expiration date of the warrants. Series 2012 Notes Exchange On February 6, 2014, the Company entered into exchange and purchase agreements with certain holders of approximately $131.7 million aggregate principal amount of outstanding Series 2012 Notes. The exchange agreements provide for the issuance, by the Company, of shares of common stock and a cash payment for the Series 2012 Notes being exchanged, and the purchase agreement provides for a cash payment for the Series 2012 Notes being repurchased. The Company issued a total of approximately 20.3 million shares of its common stock and paid an aggregate cash payment of approximately $34.2 million pursuant to the exchange and purchase agreements. Paradigm Spine On February 14, 2014, the Company entered into a credit agreement with Paradigm Spine, LLC, under which it made available to Paradigm up to $75 million to be used by Paradigm to refinance its existing credit facility and expand its domestic commercial operations. A portion of the amount available under the agreement in an aggregate principal amount equal to $50 million, net of fees, was funded at the close of the transaction. In the event that certain specified sales and other milestones occur before December 31, 2014, the Company will fund Paradigm between an additional $6.25 million and $12.5 million, at Paradigm’s discretion. In the event that additional specified sales and other milestones occur before June 30, 2015, the Company will fund up to an additional $12.5 million also at Paradigm’s discretion. Borrowings under the credit agreement bear interest at the rate of 13.0% per annum, payable quarterly in arrears. Principal repayment will commence on the eleventh interest payment date, September 30, 2016. The principal amount outstanding at commencement of repayment will be repaid in equal installments until final maturity of the loans. The loans will mature on February 14, 2019, or, if Paradigm has achieved the first milestone and the additional loan amount is provided to Paradigm, the loans will mature on August 14, 2019. Paradigm may elect to prepay the loans at any time, subject to a prepayment penalty that decreases over the life of the loans. The obligations under the credit agreement are secured by a pledge of substantially all of the assets of Paradigm and its domestic subsidiaries and, initially, certain assets of Paradigm’s German subsidiaries. 22.

We have audited the accompanying consolidated balance sheets of PDL BioPharma, Inc. as of December 31, 2013 and 2012, and the related consolidated statements of income, comprehensive income, stockholders’ equity (deficit) and cash flows for each of the three years in the period ended December 31, 2013. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of PDL BioPharma, Inc. at December 31, 2013 and 2012, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2013, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), PDL BioPharma, Inc.’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) and our report dated March 3, 2014 expressed an unqualified opinion thereon. /s/ ERNST & YOUNG LLP Redwood City, California March 3, 2014 88 ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. 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 Annual Report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer, has concluded that, as of December 31, 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. Management’s Annual Report on Internal Control over Financial Reporting PDL, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, is responsible for the preparation and integrity of our Consolidated Financial Statements, establishing and maintaining adequate internal control over financial reporting and all related information appearing in this Annual Report. We evaluated the effectiveness of our internal controls over financial reporting under the Internal Control-Integrated Framework founded by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control-Integrated Framework, our management has assessed our internal control over financial reporting to be effective as of December 31, 2013. Changes in Internal Controls There were no changes in our internal controls over financial reporting during the quarter ended December 31, 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. Our independent registered public accountants, Ernst & Young LLP, audited the Consolidated Financial Statements included in this Annual Report and have issued an audit report on the effectiveness of our internal control over financial reporting. The report on the audit of internal control over financial reporting appears below, and the report on the audit of the Consolidated Financial Statements appears in Part II, Item 8 of this Annual Report. 89 Report of Independent Registered Public Accounting Firm The Board of Directors and Stockholders of PDL BioPharma, Inc. We have audited PDL BioPharma, Inc.’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (the COSO criteria). PDL BioPharma, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, PDL BioPharma, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of PDL BioPharma, Inc. as of December 31, 2013 and 2012, and the related consolidated statements of income, comprehensive income, stockholders’ equity (deficit) and cash flows for each of the three years in the period ended December 31, 2013 of PDL BioPharma, Inc. and our report dated March 3, 2014 expressed an unqualified opinion thereon. /s/ ERNST & YOUNG LLP Redwood City, California March 3, 2014 90 ITEM 9B.
