PART I 

This Annual Report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 
1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. 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. 

As used in this Annual Report, the terms “we,” “us,” “our,” the “Company” and “PDL” mean PDL BioPharma, Inc. 
(unless the context indicates a different meaning). 

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 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, Inc. (we, us, our, PDL and the Company) pioneered humanization of monoclonal antibodies and, by 
doing so, enabled the discovery of a new generation of targeted treatments for cancer and immunologic diseases. Today, 
PDL is focused on intellectual property asset management, investing in new royalty bearing assets and maximizing the 
value of its patent portfolio and related assets. We receive royalties based on sales of humanized antibody products 
marketed today and may also receive royalty payments on additional humanized antibody products launched before final 
patent expiry of our Queen et al. patents in December 2014. Under most of our licensing agreements, we are entitled to 
receive a flat-rate or tiered royalty based upon our licensees’ net sales of covered antibodies. We have also entered into 
licensing agreements under which we have licensed certain rights for development stage products that have not yet 
reached commercialization including products that are currently in Phase 3 clinical trials. While our intellectual property 
asset management protects our current revenue streams, we compete with other entities in the pursuit of new royalty 
bearing assets. 

We were organized as a Delaware corporation in 1986 under the name Protein Design Labs, Inc. In 2006, we changed 
our name to PDL BioPharma, Inc. Until December 2008, our business included a biotechnology operation which was 
focused on the discovery and development of novel antibodies which we spun-off (the Spin-Off) as Facet Biotech 
Corporation (Facet). We continuously evaluate alternatives to increase return for our stockholders, for example, 
purchasing royalty generating assets, buying back or redeeming our convertible notes, repurchasing our common stock, 
selling the Company and paying dividends. 

2012 Dividends 

We currently utilize dividends to increase return for our stockholders. On January 18, 2012, our board of directors 
declared that the regular quarterly dividends to be paid to our stockholders in 2012 will be $0.15 per share of common 
stock, payable 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. At the 
beginning of each fiscal year, our board of directors reviews the Company’s total annual dividend payments for the prior 

1 

 
  
  
  
  
  
  
  
  
  
  
year and determines whether to increase, maintain or decrease the regular 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. 

Royalty Asset Acquisitions 

The last of PDL’s Queen et al. patents expire in December 2014, with the obligation to pay royalties under our various 
license agreements expiring sometime thereafter. We do not expect to receive any meaningful revenue from the 
inventories produced prior to the expiration of our Queen et al. patents beyond the first quarter of 2016. Consequently, 
we are interested in acquiring new royalty generating assets if such royalty assets can be acquired on terms that allow us 
to increase the return to our stockholders. Our royalty asset focus is on commercial stage therapies having strong 
economic fundamentals and intellectual property protection, with less of an emphasis on therapeutic area. While we will 
consider transactions of various sizes, our preference is for assets with a net present value of $75 million to $150 million. 

Convertible Notes 

We have actively been working to restructure the Company’s capital and reduce the potential dilution associated with 
our convertible notes. As part of those efforts, in May 2011, we issued $155.3 million in aggregate principal of 3.75% 
Senior Convertible Notes due 2015 (May 2015 Notes) in an underwritten public offering.  Our May 2015 Notes “net 
share settle,” generally 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 proceeds from 
our May 2015 Notes were used to redeem the outstanding principal amount of our 2.00% Convertible Senior Notes due 
February 15, 2012 (2012 Notes). As a result, our 2012 Notes are no longer outstanding. By issuing our May 2015 Notes 
with the net share settle feature and redeeming our 2012 Notes we eliminated 19.7 million shares of potential dilution to 
our stockholders. 

In January 2012, we completed an exchange transaction where we exchanged and subsequently retired approximately 
$169.0 million aggregate principal amount, representing approximately 93.9%, of our 2.875% Convertible Senior Notes 
due February 15, 2015 (February 2015 Notes), for approximately $169.0 million aggregate principal amount of new 
2.875% Series 2012 Convertible Senior Notes due February 15, 2015 (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. Following settlement of the private exchanges on February 2, 2012, $1.0 million of our February 
2015 Notes and $179.0 million of our Series 2012 Notes were outstanding. Like our May 2015 Notes, our Series 2012 
Notes net share settle. 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. 

Effect of December 15, 2011, Dividend Payment on Conversion Rates for the Convertible Notes 

In connection with the December 15, 2011, dividend payment, the conversion rates for our convertible notes increased. 
The conversion rate for our February 2015 Notes was adjusted to 155.396 common shares per $1,000 principal amount, 
or approximately $6.44 per share, effective December 9, 2011. The conversion rate for our May 2015 Notes was adjusted 
to 135.9607 common shares per $1,000 principal amount, or approximately $7.36 per share, effective December 6, 2011. 
The adjustments were based on the amount of the dividend and the trading price of our stock under the terms of the 
applicable indenture. The conversion rate for our new Series 2012 Notes is 155.396 shares of the Company’s common 
stock per $1,000 principal amount, which is equivalent to an initial conversion price of approximately $6.44 per share of 
common stock. 

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 patent (‘761 patent), which is the last to expire of our U.S. patents, 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. 

The European Patent No. 0 451 216B (‘216B Patent) expired in Europe in December 2009. We have been granted 
Supplementary Protection Certificates (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. These SPCs effectively extend our 
patent protection with respect to these 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. In the 
year ending December 31, 2011, approximately 33% of our royalty revenues were derived from sales of products that 
were made in Europe and sold outside of the United States. 

 Licensing Agreements 

We have entered into licensing agreements with numerous entities that are independently developing or have developed 
humanized antibodies under which we have licensed certain rights under our Queen et al. patents to make, use, sell, offer 
for sale and import humanized antibodies. We receive royalties on net sales of products that are made, used 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. Our licensing agreements generally entitle us to royalties following the expiration of our patents 
with respect to sales of products manufactured prior to patent expiry in jurisdictions providing patent protection. We also 
expect to receive minimal 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 were $137.3 million, $130.1 million and $154.7 million for the years ended 
December 31, 2011, 2010 and 2009, respectively. Our total revenues from foreign based licensees were $224.7 million, 
$214.9 million and $163.5 million for the years ended December 31, 2011, 2010 and 2009, respectively. 

Licensing Agreements for Marketed Products 

In the year ended December 31, 2011, we received royalties on sales of the seven humanized antibody products listed 
below, all of which are currently approved for use by the U.S. Food and Drug Administration (FDA) and other 
regulatory agencies outside the United States.

For the years ended December 31, 2011, 2010 and 2009, we received royalty revenues under license agreements of 
approximately $351.6 million, $343.5 million and $305.0 million, respectively. 

In June 2010, after results from a clinical trial raised concerns about the efficacy and safety of Mylotarg®, Pfizer Inc. 
(Pfizer), the parent company of Wyeth, announced that it will be discontinuing commercial availability of Mylotarg. For 
the years ended December 31, 2011, 2010 and 2009, we received royalties of $0.3 million, $0.9 million and $1.9 million 
for sales of Mylotarg, respectively. 

Genentech 

We entered into a master patent license agreement, effective September 25, 1998, under which we granted Genentech a 
license under our Queen et al. patents to make, use and sell certain antibody products. Our master patent license 
agreement with Genentech provides for a tiered royalty structure under which the royalty rate Genentech must pay on 
royalty-bearing products sold in the United States or manufactured in the United States and used or sold anywhere in the 
world (U.S.-based Sales) in a given calendar year decreases on incremental U.S.-based Sales above certain sales 
thresholds based on 95% of the underlying gross U.S.-based Sales. The net sales thresholds and the applicable royalty 
rates are outlined below: 

Aggregate Net Sales on Product Made or Sold in U.S.
Net sales up to $1.5 billion ………………………………………..    
Net sales between $1.5 billion and $2.5 billion …………………...   
Net sales between $2.5 billion and $4.0 billion …………………...   
Net sales exceeding $4.0 billion …………………………………..    

  Royalty Rate   
3.0% 
2.5% 
2.0% 
1.0% 

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

With respect to royalty-bearing products that are both manufactured and sold outside of the United States (ex-U.S.-based 
Manufacturing and Sales), the royalty rate that we receive from Genentech is a fixed rate of 3.0% based on 95% of the 
underlying gross 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, particularly in light of the 2009 
acquisition of Genentech by F. Hoffman LaRoche, Ltd. (Roche). 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:

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

In the years ended December 31, 2011 and 2010, PDL received royalties generated from three of Genentech’s licensed 
products that were ex-U.S.-based manufactured and sold: Herceptin, Avastin and Xolair. Prior to 2010, only Herceptin 
and Xolair generated royalties from ex-U.S.-based Manufacturing and Sales. Roche has announced that there are new 
plants in Singapore for the production of Avastin and Lucentis. The plants were registered by the FDA to produce bulk 
Avastin and Lucentis for use in the United States in 2010 and Roche expects the plants to be registered to produce bulk 
Avastin and Lucentis for use in Europe. 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. 

Elan 

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 (cid:2)4 in patients with 
multiple sclerosis. Under the agreement, we are entitled to receive a flat royalty rate in the low single digits based on 
Elan’s net sales of the Tysabri product. 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. 

Wyeth 

We entered into a patent license agreement, effective September 1, 1999, under which we granted to Wyeth a license 
under our Queen et al. patents to make, use and sell antibodies that bind to CD33, an antigen that is found in about 80% 
of patients with acute myeloid leukemia, and conjugated to a cytotoxic agent. Under the agreement, we are entitled to 
receive a flat royalty rate in the low single digits based on Wyeth’s net sales of the Mylotarg product. The agreement 
continues until the expiration of the last to expire of our Queen et al. patents but may be terminated (i) by Wyeth 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 June 2010, after results from a recent clinical trial raised concerns 
about the efficacy and safety of Mylotarg, Pfizer, the parent company of Wyeth, announced that it will be discontinuing 
commercial availability of Mylotarg. 

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

Licensing Agreements for Non-Marketed Products 

We have also entered into licensing agreements under which we have licensed certain rights under our Queen et al. 
patents to make, use and sell certain products in development that have not yet reached commercialization. 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, trastuzumab-DM1 (T-DM1) which is an experimental, antibody-
drug conjugate that links Herceptin to a cytotoxic, or cell killing agent, DM1, is being developed by Genentech. This 
approach is designed to increase the already significant tumor fighting ability of Herceptin by coupling it with an 
additional cell killing agent that is efficiently and simultaneously delivered to the targeted cancer cells by the antibody. 
Two additional examples are the Eli Lilly and Company (Lilly) and Wyeth licensed antibodies for the treatment of 
Alzheimer’s disease that are currently in Phase 3 clinical trials. If Lilly’s antibody for Alzheimer’s disease is approved, 
we would also be entitled to receive a royalty based on a “know-how” license for technology provided in the design of 

5 

 
  
  
  
  
  
  
  
  
  
this antibody. Unlike the royalty for the patent license, the royalty payable for “know-how” runs for 12.5 years after the 
product’s initial commercialization. 

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. In 2011, we entered into 
settlement agreements, which terminated several challenges against the Queen et al patents in the U.S. and Europe, 
including a declaratory judgment proceeding in U.S. District Court initiated by MedImmune, LLC (MedImmune), two 
interference proceedings in the United States Patent and Trademark Office provoked by UCB Pharma S.A. (UCB) and 
an opposition proceeding in Europe against our European Queen Patent involving UCB, Novartis AG (Novartis) and 
BioTransplant Inc. (BioTransplant). 

Genentech / Roche Matter 

Communications with Genentech regarding European SPCs 

In August 2010, we received a letter from Genentech, sent on behalf of Roche and Novartis, asserting that Avastin, 
Herceptin, Lucentis and Xolair (the Genentech Products) do not infringe the SPCs granted to PDL by various countries 
in Europe for each of the Genentech Products and seeking a response from PDL to these assertions. Genentech did not 
state what actions, if any, it intends to take with respect to its assertions. PDL’s SPCs were granted by the relevant 
national patent offices in Europe and specifically cover the Genentech Products. The SPCs covering the Genentech 
Products effectively extend our European patent protection for the ‘216B Patent generally until December 2014, except 
that the SPCs for Herceptin will generally expire in July 2014. 

Genentech’s letter does not suggest that the Genentech Products do not infringe PDL’s U.S. patents to the extent that 
such Genentech Products are U.S.-based Sales. Genentech’s quarterly royalty payments received after receipt of the 
letter have included royalties generated on all worldwide sales of the Genentech Products. 

If Genentech is successful in asserting this position, then under the terms of our license agreements with Genentech, it 
would not owe us royalties on sales of the Genentech Products that are ex-U.S.-based Manufacturing and Sales. 
Royalties on sale of the Genentech Products that are ex-U.S.-based Manufacturing and Sales accounted for 
approximately 33% of our royalty revenues for the year ended December 31, 2011. Based on announcements by Roche 
regarding moving more manufacturing outside of the United States, we expect this amount to increase in the future. 

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

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

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

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

In November 2010, Genentech and Roche filed a motion to dismiss our complaint against them in which we seek to 
enforce our rights under the 2003 settlement agreement with Genentech. Genentech and Roche's motions to dismiss 
under Nevada Rule of Civil Procedure 12(b)(5) alleged that all of our claims for relief relating to the 2003 settlement 
agreement should be dismissed because the 2003 settlement agreement applies only to our U.S. patents. In addition, 
Roche filed a separate motion to dismiss our complaint under Nevada Rule of Civil Procedure 12(b)(2) on the ground 

6 

 
  
  
  
  
  
  
  
  
  
  
  
  
that the Nevada court lacks personal jurisdiction over Roche. On July 7, 2011, the Second Judicial District Court of 
Nevada ruled in favor of us on the two motions to dismiss filed by Genentech and Roche. The court denied Genentech 
and Roche's motion to dismiss four of our five claims for relief and, further, denied Roche's separate motion to dismiss 
for lack of personal jurisdiction. The court dismissed one of our claims that Genentech committed a bad-faith breach of 
the covenant of good faith and fair dealing stating that, based on the current state of the pleadings, no "special 
relationship" had been established between Genentech and us as required under Nevada law. On November 1, 2011, the 
Nevada court issued an order accepting Roche’s stipulation of waiver to its personal jurisdiction defense. As a result of 
the order, Roche is foreclosed from reliance on lack of personal jurisdiction in defending against our claims. 

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

The court has scheduled trial to commence on May 13, 2013. The outcome of this litigation is uncertain and we may not 
be successful in our allegations. 

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 2011, 2010 and 
2009, Genentech accounted for 86%, 86% and 71% of our revenues, respectively; Elan accounted for 12%, 10% and 9% 
of our revenues, respectively; and MedImmune accounted for zero, zero and 13% of our revenues, respectively. 

Employees 

As of February 22, 2012, we had less than ten full-time employees managing our intellectual property, our licensing 
operations and other corporate activities as well as providing for certain essential reporting and management functions of 
a public company. None of our employees are covered by a collective bargaining agreement.

ITEM 1A.        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.” 

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 other 
sources of royalty 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. 

Unless we are able to acquire patents or other sources of royalty revenue on commercially reasonable terms, we will no 
longer receive patent-related royalties once our licensees have sold all their inventory of licensed product that was 
manufactured before the expiration of the Queen et al. patents. If we are unsuccessful in acquiring new sources of royalty 
revenue, we will likely liquidate our business. 

8 

 
  
  
  
  
  
  
  
  
  
If we fail to meet the expectations of securities analysts or investors, or if adverse conditions prevail or are perceived to 
prevail with respect to our business, the price of the common stock would likely drop significantly. 

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 (EPO). 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 Avastin, Herceptin, Xolair, Lucentis and Tysabri to the extent these products are made 
and sold outside the United States (the SPC Products). 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 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 
and/or whether the product named in the SPC actually infringes those claims and whether the SPC was properly granted 
pursuant to controlling European law. Such a proceeding would involve complex legal and factual questions and 
proceedings. 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 33% of our royalty revenues for the year ended December 31, 2011. Based on 
announcements by Roche regarding moving manufacturing outside of the United States, we expect this amount to 
increase in the future. 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 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 86%, 86% and 71% of our revenues for the years ended December 31, 2011, 2010 and 2009, 
respectively. Our future success 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. For example, 60% of the royalties we currently receive from Genentech are dedicated to 
service the debt related to our QHP PhaRMASM Senior Secured Notes due March 15, 2015 (Non-recourse Notes) that 
we, through our wholly-owned subsidiary, QHP Royalty Sub LLC, issued in November 2009. 

In August 2010, we received a letter from Genentech on behalf of Roche and Novartis asserting that the Genentech 
Products do not infringe our SPCs for each of the Genentech Products. If Genentech is successful in asserting this 
position, then under the terms of our license agreements with Genentech, it would not owe us royalties on ex-U.S.-based 
Manufacturing and Sales of the Genentech Products. These royalties accounted for approximately 33% of our royalty 
revenues for the year ended December 31, 2011. If Roche, as Roche has publicly announced, moves more manufacturing 
outside of the United States, this percentage will increase. 

We believe that these SPCs are enforceable against the Genentech Products and intend to vigorously assert our SPC-
based patent rights. If we are unable to resolve the dispute with Genentech, we will incur significant additional costs and 
senior management time in asserting our rights under our various agreements with Genentech, whether through 
continued litigation, arbitration or otherwise. To the extent Genentech stops or reduces payment of royalties on ex-U.S.-
based Manufacturing and Sales of the Genentech Products, this would have a material negative impact on our cash flow 
and our ability to pay dividends in the future and would also cause us to extend the anticipated repayment of our Non-

9 

 
  
  
  
  
  
  
  
  
recourse Notes due in March 2015 for which we currently anticipate full repayment in the third quarter of 2012. See 
“Item 3—Legal Proceedings.” 

Our licensees 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 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’ 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 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 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 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. Other licensed 
products have been suspended from marketing and commercial distribution, such as Mylotarg, which is currently 
suspended, and Tysabri, which was temporarily suspended and then returned to the market. In such a case, 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 face competition. 

Our licensees face competition from other pharmaceutical and biotechnology companies. The introduction of new 
competitive products or follow-on biologics may result in lost market share for our licensees, reduced use of licensed 
products, lower prices and/or reduced licensed product sales, any of which could reduce our royalty revenues and have a 
material adverse effect on our results of operations. 

We may enter into acquisitions or other material royalty asset transactions now and in the future and such 
acquisitions may not produce anticipated royalty revenues. 

We are engaged in a continual review of opportunities to acquire existing royalty assets 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 royalty 
asset acquisition opportunities in our markets could increase the price we pay for royalty assets we acquire and could 
reduce the number of potential acquisition targets. The success of our royalty asset acquisitions is based on our ability to 
make accurate assumptions regarding the valuation, timing and amount of royalty payments. The failure of any of these 
acquisitions to produce anticipated royalty revenues may materially and adversely affect our financial condition and 
results of operations. 

10 

 
  
  
  
  
  
  
  
  
  
We intend to reserve from time to time a certain amount of cash 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 February 2, 2012, $155.3 million in principal remained outstanding under our May 2015 Notes, $1.0 million in 
principal remained outstanding under our February 2015 Notes and $179.0 million in principal remained outstanding 
under our Series 2012 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, $179.0 million as of February 2, 2012. 

Holders of the February 2015 Notes may convert their notes at any time, at the holder’s election. 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. 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 “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. 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 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 intend to reserve from time to time a certain amount of cash 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 royalty asset acquisition. 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 of any of our February 2015 Notes, our May 2015 Notes or our Series 2012 Notes into shares of 
our common stock would have a dilutive effect which 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. Our February 2015 Notes are convertible at any time at the holder’s election. 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 February 2, 2012, for our February 2015 Notes and Series 2012 Notes is 155.396 shares of 
common stock per $1,000 principal amount or a conversion price of approximately $6.44 per share of common stock and 
the conversion rate for our May 2015 Notes is 135.9607 shares of common stock per $1,000 principal amount, or a 
conversion price of approximately $7.36 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 that may affect the value of our common stock. 

In connection with the issuance of our May 2015 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. 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’ deficit. In 
connection with hedging these transactions, the hedge 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 are likely to do so during any cash 
settlement averaging period related to any conversion of our May 2015 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. 

In addition, we intend to exercise the purchased call options whenever May 2015 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 may result in an 
increase in dilution with respect to our common stock. 

Changes in the third-party reimbursement environment may affect product sales from which we generate royalty 
revenues. 

Sales of products from which we generate royalties 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 
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; 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. 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 by, for example, decreasing the number of patients 
covered by insurance policies or increasing costs associated with such policies. 

 Our revenues and operating results will likely fluctuate in future periods. 

Our royalty revenues may be unpredictable and fluctuate because they depend upon, among other things, the rate of 
growth of sales of licensed products as well as the mix of U.S.-based Sales and ex-U.S.-based Manufacturing and Sales 
in connection with our master patent license agreement with Genentech. 

The Genentech agreement provides for a tiered royalty structure. The royalty rate Genentech must pay on 95% of the 
underlying gross U.S.-based Sales in a given calendar year decreases 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 
declines 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 receive from Genentech in the second calendar quarter, which would be for 
Genentech’s sales from the first calendar quarter, has been and is expected to continue to be higher than the average 
royalty rate for following quarters. The average royalty rate for payments we receive from Genentech is generally lowest 

12 

 
  
 
 
  
  
  
  
  
  
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 bear royalties at a 1% royalty rate. With respect to the 
ex-U.S.-based Manufacturing and Sales, the royalty rate that we receive from Genentech is 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, particularly in light of 
the 2009 acquisition of Genentech by Roche. For example, Roche has announced plans to move certain Avastin and 
Lucentis manufacturing to Singapore. 

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 Eurodollar, 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, 
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 Eurodollar currency fluctuations, we hedge Eurodollar currency exposures with Eurodollar forward 
contracts and Eurodollar option contracts (collectively, Eurodollar contracts) to offset the risks associated with these 
Eurodollar 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 Eurodollar 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 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 new royalty bearing assets and maximizing the value of our patent portfolio and related assets, 
which requires only a small number of employees. Due to the unique 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. 

13 

 
  
  
  
  
  
  
  
  
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, 2011, the total lease payments for the duration of the guarantee, 
which runs through December 2021, are approximately $110.8 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 (Abbott) acquired Facet and later renamed the company Abbott 
Biotherapeutics Corp. 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.” 

We depend on our licensees for the determination of royalty payments. We may not be able to detect errors and 
payment calculations may call for retroactive adjustments. 

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 
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. 

ITEM 1B.        UNRESOLVED STAFF COMMENTS 

None. 

ITEM 2.           PROPERTIES 

We lease 4,800 square feet of office space in Incline Village, Nevada, which serves as our corporate headquarters. The 
lease expires in May 2012. 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 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, Abbott acquired Facet and later 
renamed the company Abbott Biotherapeutics Corp. To date, Facet has satisfied all obligations under the Redwood City 
lease.

ITEM 3.           LEGAL PROCEEDINGS 

Genentech / Roche Matter 

Communications with Genentech regarding European SPCs 

In August 2010, we received a letter from Genentech, sent on behalf of Roche and Novartis, asserting that the Genentech 
Products do not infringe the SPCs granted to PDL by various countries in Europe for each of the Genentech Products and 
seeking a response from PDL to these assertions. Genentech did not state what actions, if any, it intends to take with 
respect to its assertions. PDL’s SPCs were granted by the relevant national patent offices in Europe and specifically 
cover the Genentech Products. The SPCs covering the Genentech Products effectively extend our European patent 
protection for the ‘216B Patent generally until December 2014, except that the SPCs for Herceptin will generally expire 
in July 2014. 

Genentech’s letter does not suggest that the Genentech Products do not infringe PDL’s U.S. patents to the extent that 
such Genentech Products are U.S.-based Sales. Genentech’s quarterly royalty payments received after receipt of the 
letter have included royalties generated on all worldwide sales of the Genentech Products. 

If Genentech is successful in asserting this position, then under the terms of our license agreements with Genentech, it 
would not owe us royalties on sales of the Genentech Products that are both manufactured and sold outside of the United 
States. Royalties on sale of the Genentech Products that are ex-U.S.-based Manufacturing and Sales accounted for 
approximately 33% of our royalty revenues for the year ended December 31, 2011. Based on announcements by Roche 
regarding moving more manufacturing outside of the United States, we expect this amount to increase in the future. 

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

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

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

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

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

15 

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

The court has scheduled trial to commence on May 13, 2013. The outcome of this litigation is uncertain and we may not 
be successful in our allegations. 

Other Legal Proceedings 

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

As of February 15, 2012, we had approximately 151 common stockholders of record. Most of our outstanding shares of 
common stock are held of record by one stockholder, Cede & Co., a 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 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 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. 

On February 25, 2011, our board of directors declared a regular quarterly dividend of $0.15 per share of common stock. 
On March 15, June 15, September 15 and December 15 of 2011, we paid quarterly cash dividends of approximately 
$21.0 million or $0.15 per share to stockholders of record on March 8, June 8, September 8 and December 8 of 2011, the 
record dates for each of the dividend payments, respectively. 

In April and October 2010, we paid cash dividends of $59.9 million, or $0.50 per share of common stock, and $69.8 
million, or $0.50 per share of common stock, respectively, to our stockholders.

ITEM 7.           MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
                          RESULTS OF OPERATIONS 

Overview 

PDL BioPharma Inc. (we, us, our, PDL and the Company) pioneered humanization of monoclonal antibodies and, by 
doing so, enabled the discovery of a new generation of targeted treatments for cancer and immunologic diseases. Today, 
PDL is focused on intellectual property asset management, investing in new royalty bearing assets and maximizing the 
value of its patent portfolio and related assets. We receive royalties based on sales of humanized antibody products 
marketed today and may also receive royalty payments on additional humanized antibody products launched before final 
patent expiry in December 2014. Under most of our licensing agreements, we are entitled to receive a flat-rate or tiered 
royalty based upon our licensees’ net sales of covered antibodies. We have also entered into licensing agreements under 
which we have licensed certain rights 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 a biotechnology operation which was focused on the discovery and 
development of novel antibodies which we spun-off (the Spin-Off) as Facet. 

2011 Developments 

Resolution of Challenges against 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, LLC (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 ceased any support, financial or otherwise, of any party involved in the appeal 
proceeding before the European Patent Office (EPO) relating to the opposition against the European Patent No. 0 451 
216B (‘216B Patent) including the opposition owned by BioTransplant Inc. (BioTransplant).

Settlement with UCB 

On February 2, 2011, we reached a settlement with UCB Pharma S.A. (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 million to PDL and termination of pending patent interference 
proceedings before the U.S. Patent and Trademark office (PTO) involving our U.S. Patent No. 5,585,089 patent (the ‘089 
Patent) and our U.S. Patent No. 6,180,370 (‘370 Patent) 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 AG (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 cancelled the appeal proceeding and 
terminated the opposition proceeding in its entirety, with the result that the 2007 EPO decision upholding the claims of 
our ‘216B Patent as valid is the final decision of the EPO. In the year ending December 31, 2011, approximately 33% 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 

Communications with Genentech regarding European SPCs 

In August 2010, we received a letter from Genentech, sent on behalf of Roche and Novartis, asserting that Avastin®, 
Herceptin®, Lucentis® and Xolair® (the Genentech Products) do not infringe the supplementary protection certificates 
(SPCs) granted to PDL by various countries in Europe for each of the Genentech Products and seeking a response from 
PDL to these assertions. Genentech did not state what actions, if any, it intends to take with respect to its assertions. 
PDL’s SPCs were granted by the relevant national patent offices in Europe and specifically cover the Genentech 
Products. The SPCs covering the Genentech Products effectively extend our European patent protection for the ‘216B 
Patent generally until December 2014, except that the SPCs for Herceptin will generally expire in July 2014. 

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

If Genentech is successful in asserting this position, then under the terms of our license agreements with Genentech, it 
would not owe us royalties on sales of the Genentech Products that are made and sold outside of the United States (ex-
U.S.-based Manufacturing and Sales). Royalties on sale of the Genentech Products that are ex-U.S.-based Manufacturing 
and Sales accounted for approximately 33% of our royalty revenues for the year ended December 31, 2011. Based on 
announcements by Roche regarding moving more manufacturing outside of the United States, we expect this amount to 
increase in the future. 

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

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

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

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

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

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

The court has scheduled trial to commence on May 13, 2013. The outcome of this litigation is uncertain and we may not 
be successful in our allegations. 

Convertible Notes 

We have actively been working to restructure the Company’s capital and reduce dilution associated with our convertible 
notes. As part of those efforts, in May 2011, we issued $155.3 million in aggregate principal of 3.75% Senior 
Convertible Notes due 2015 (May 2015 Notes) in an underwritten public offering. Our May 2015 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 common stock. The proceeds from our May 2015 
Notes were used to redeem the outstanding principal amount of our 2.00% Convertible Senior Notes due February 15, 
2012 (2012 Notes). As a result, our 2012 Notes are no longer outstanding. By issuing our May 2015 Notes with the net 
share settle feature and redeeming our 2012 Notes, we eliminated 19.7 million shares of potential dilution to our 
stockholders. 

In January 2012, we completed an exchange transaction where we exchanged and subsequently retired approximately 
$169.0 million aggregate principal amount, representing approximately 93.9%, of our 2.875% Convertible Senior Notes 
due February 15, 2015 (February 2015 Notes), for approximately $169.0 million aggregate principal amount of new 
2.875% Series 2012 Convertible Senior Notes due February 15, 2015 (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. Following settlement of the private exchanges on February 2, 2012, $1.0 million of our February 
2015 Notes and $179.0 million of our Series 2012 Notes were outstanding. Like our May 2015 Notes, our Series 2012 
Notes net share settle. The effect of issuing $179.0 million aggregate principal of our Series 2012 Notes with the net 

22 

 
  
  
  
  
  
  
  
  
share settle feature in exchange for our February 2015 Notes was the reduction of 27.8 million shares of potential 
dilution to our stockholders. 

Effect of December 15, 2011, Dividend Payment on Conversion Rates for the Convertible Notes 

In connection with the December 15, 2011, dividend payment, the conversion rates for our convertible notes increased. 
The conversion rate for our February 2015 Notes was adjusted to 155.396 common shares per $1,000 principal amount, 
or approximately $6.44 per share, effective December 9, 2011.The conversion rate for our May 2015 Notes was adjusted 
to 135.9607 common shares per $1,000 principal amount, or approximately $7.36 per share, effective December 6, 
2011.The adjustment was based on the amount of the dividend and the trading price of our stock under the terms of the 
applicable indenture. The conversion rate for our new Series 2012 Notes is 155.396 shares of the Company’s common 
stock per $1,000 principal amount, which is equivalent to an initial conversion price of approximately $6.44 per share of 
common stock. 

2012 Dividends 

On January 18, 2012, our board of directors declared regular quarterly dividends of $0.15 per share of common stock, 
payable 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. 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. 

Critical Accounting Policies and Uses of Estimates 

The preparation of our financial statements in conformity with U.S. generally accepted accounting principles (GAAP) 
requires management to make estimates and assumptions that affect the amounts reported in our financial statements and 
accompanying notes. Actual results could differ materially from those estimates. The items in our financial statements 
requiring significant estimates and judgments comprise: 

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 and payments 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 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, 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 are typically reported 
in the same period in which we receive payment from our licensees. 

We may also receive minimal 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. 

Foreign Currency Hedging 

We hedge Eurodollar currency exposures related to our licensees’ product sales with Eurodollar forward contracts and 
Eurodollar option contracts. In general, these contracts are intended to offset the underlying Eurodollar market risks in 
our royalty revenues. We do not enter into speculative foreign currency transactions. We have designated the Eurodollar 
contracts 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 Eurodollar contracts is estimated using pricing models using readily observable 
inputs from actively quoted markets. The aggregate unrealized gain or loss on the effective portion of our Eurodollar 
contracts, net of estimated taxes, is recorded in stockholders’ deficit as accumulated other comprehensive income (loss). 
Gains or losses on cash flow hedges are recognized as royalty revenue in the same period that the hedged transaction, 

23 

 
  
  
  
  
  
  
  
  
  
  
  
royalty revenue, impacts earnings. The hedge effectiveness is dependent upon the amounts of future royalties and, if 
future royalties, based on Eurodollar, 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%. 

Convertible Notes 

In 2011 we issued our May 2015 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 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%, which represents the 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, 
2011, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately 
$110.8 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. In April 2010, Abbott 
Laboratories acquired Facet and later renamed the company Abbott Biotherapeutics Corp. 

We recorded a liability of $10.7 million on our Consolidated Balance Sheets as of December 31, 2011 and 2010, for the 
estimated fair value of 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. On a quarterly basis, we review the underlying cash 
flow analysis assumptions and update them if necessary. 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 2011, 2010 and 2009 Financial Results 

(cid:3)(cid:4)  Our net income for the years ended December 31, 2011, 2010 and 2009, was $199.4 million, $91.9 million and 

$189.7 million, respectively; 

(cid:3)(cid:4)  At December 31, 2011, we had cash, cash equivalents and investments of $227.9 million as compared with $248.2 

million at December 31, 2010; and 

(cid:3)(cid:4)  At December 31, 2011, we had $473.7 million in total liabilities as compared with $640.8 million at December 31, 

2010. 

Revenues 

Revenues were $362.0 million, $345.0 million and $318.2 million for the years ended December 31, 2011, 2010 and 
2009, respectively, and consist of royalty revenues as well as other license related revenues. During the years ended 
December 31, 2011, 2010 and 2009, our royalty revenues consisted of royalties and maintenance fees earned on sales of 
products under license agreements associated with our Queen et al. patents. 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 and a $12.5 million payment in 2009 from our 
legal settlement with Alexion. Our revenues consist primarily of royalty revenues, which represent more than 95% of 
total revenues for each of the past three years. Revenue for the year ended December 31, 2011, is net of the payment 
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, 2011, 2010 and 2009, is presented below:

In the year ended December 31, 2011, we received royalties on sales of the seven humanized antibody products listed 
below, all of which are currently approved for use by the U.S. Food and Drug Administration (FDA) and other 
regulatory agencies outside the United States. 

The licensees with commercial products as of December 31, 2011, are listed below: 

Licensee 
Genentech, Inc. (Genentech) ………………….   Avastin®

Elan Corporation, Plc (Elan) …………………..  Tysabri® 

Wyeth Pharmaceuticals, Inc. (Wyeth) ………...   Mylotarg® 

Chugai Pharmaceutical Co., Ltd. (Chugai) ……  Actemra® 

In June 2010, after results from a clinical trial raised concerns about the efficacy and safety of Mylotarg®, Pfizer Inc. 
(Pfizer), the parent company of Wyeth, announced that it would be discontinuing commercial availability of Mylotarg. 
Approval for Raptiva®, which was marketed by Genentech and Merck Serono S.A., was suspended in the European 
Union and in Canada in February 2009 and the product was withdrawn from the market in the United States in April 
2009; accordingly, we do not expect to receive royalties on future sales of Raptiva.

Prior to 2010, we also received royalties for Synagis, which is marketed by MedImmune. In February 2011, we settled 
our dispute with MedImmune, and will not receive royalties on past or future sales of Synagis. 

For the years ended December 31, 2011, 2010 and 2009, we received royalties of $0.3 million, $0.9 million, and $1.9 
million for sales of Mylotarg. For the years ended December 31, 2011 and 2010, we did not receive royalties for sales of 
Synagis or Raptiva. For the year ended December 31, 2009, we received royalties of $40.7 million and $1.2 million for 
sales of Synagis and Raptiva, respectively. 

Under most of the agreements for the license of rights under our Queen et al. patents, we receive a flat-rate 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. Our agreement with 
Genentech provides for a tiered royalty structure under which the royalty rates Genentech must pay on the U.S.-based 
Sales in a given calendar year decreases on incremental U.S.-based Sales above certain sales thresholds based on 95% of 
the underlying gross U.S.-based Sales. As a result of the tiered royalty structure, Genentech’s average annual royalty rate 
for a given year will decline as Genentech’s U.S.-based Sales increase during that year. Because we receive royalties in 
arrears, the average royalty rate for the payments we receive from Genentech in our second calendar quarter for 
Genentech’s sales from the first calendar quarter has been and is expected to continue to be higher than the average 
royalty rate for following quarters. The average royalty rate for payments we receive 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 bear royalties at the 1% royalty rate. 

The net sales thresholds and the applicable royalty rates for Genentech’s U.S.-based Sales are outlined below: 

Aggregate Net Sales on Product Made or Sold in U.S. 
Net sales up to $1.5 billion ……………………………………...    
Net sales between $1.5 billion and $2.5 billion …………………   
Net sales between $2.5 billion and $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, the royalty rate that we receive from Genentech is 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, 
particularly in light of the 2009 acquisition of Genentech by Roche and Roche’s announcement that there are new plants 
in Singapore for the production of Avastin and Lucentis. 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. We were not provided the reasons for the shift in the manufacturing split between U.S.-based Sales and ex-
U.S.-based Manufacturing and Sales.

For the year ended December 31, 2011, compared to December 31, 2010 

Royalty revenues increased 2% for the year ended December 31, 2011, when compared to the same period in 2010. The 
growth is primarily driven by increased net sales of Lucentis, Herceptin and Tysabri by our licensees. Net sales of 
Avastin, Herceptin and Lucentis 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 Herceptin increased $0.7 billion or 13% compared to the same period for the prior year. 
Roche recently reported that global sales of Herceptin for HER2-postive breast cancer and advanced stomach 
cancer increased 8% in the first nine months of 2011 driven by further penetration in the early and metastatic 
breast cancer settings, particularly in emerging markets. Additionally, Roche reported that sales continue to 
benefit from uptake in advanced HER2-positive stomach cancer in Europe and other markets. While Herceptin net 
sales increased 13%, royalties on Herceptin only increased 5% due to a shift in site of manufacture: ex-U.S. 
manufactured and sold Herceptin declined to 35% compared to 44% for the same period in 2010. 

Reported sales of Lucentis increased $1.0 billion or 33% compared to the same period for the prior year. Lucentis 
is approved for the treatment of age-related macular degeneration in the United States and in Europe and received 
approval for the treatment of macular edema following retinal vein occlusion in June 2010 in the United States 
and June 2011 in Europe. Reported sales in 2011 increased 27% in the United States and 38% internationally. 

Reported sales of Tysabri increased $0.3 billion or 22% 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 decreased $0.1 billion or 2% compared to the same period for the prior year. Roche 
recently reported that sales in the United States were negatively impacted by reimbursement uncertainty regarding 
the metastatic breast cancer indication which was revoked by the U.S. Food and Drug Administration in 
November 2011. In Europe, austerity measures and declines in the metastatic breast cancer indication also 
affected sales. Additionally, Roche reported that sales of Avastin for advanced colorectal, breast, lung and kidney 
cancer and for relapsed glioblastoma, rose 9% in international markets, including China, for the first nine months 
of 2011 driven by a positive uptake of the product. 

For the year ended December 31, 2010, compared to December 31, 2009 

Excluding royalties for Synagis, royalty revenues for the year ended December 31, 2010, increased 30% when compared 
to the same period of 2009. The growth was primarily driven by increased sales of Avastin, Herceptin and Lucentis by 
our licensees.

(cid:3) 

(cid:3) 

Reported net sales of Avastin increased $0.8 billion or 15% compared to the same period for the prior year. In 
addition, net Ex-U.S. manufactured and sold Avastin accounted for 21% of net sales compared to zero the same 
period for the prior year. 

Reported net sales of Herceptin increased $0.5 billion or 11% compared to the same period for the prior year. 
Also, net Ex-U.S. manufactured and sold Herceptin increased $1.0 billion or 68% compared to the same period 
for the prior year. 

Reported net sales of Lucentis increased $0.9 billion or 43% when compared to the same period for the prior year. 
Ex-U.S. net sales of Lucentis increased 51% compared to the same period for the prior year and represented 53% 
of total global net sales.

In February 2011, we settled our dispute with MedImmune and will not receive royalties on past or future sales of 
Synagis. 

Foreign currency exchange rates also impact our revenue results. 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, 
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. For the year ended December 31, 2011, royalty revenue was favorably impacted by 
changes in foreign currency compared to the year ended December 31, 2010. In comparison, for the year ended 
December 31, 2010, royalty revenue was unfavorably impacted by changes in foreign currency compared to the year 
ended December 31, 2009. 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. 

We hedge Eurodollar exposures related to our licensees’ product sales with Eurodollar contracts. In general, these 
contracts are intended to offset the underlying Eurodollar currency market risks in our royalty revenues. We have 
designated the Eurodollar contracts as cash flow hedges. The aggregate unrealized gain or loss on our Eurodollar 
contracts, net of estimated taxes, on the effective portion of the hedge is recorded in stockholders’ deficit as accumulated 
other comprehensive income (loss). Gains or losses on cash flow hedges are recognized as royalty revenue in the same 
period that the hedged transaction, royalty revenue, impacts earnings. For the years ended December 31, 2011 and 2010, 
we recognized $1.0 million and $5.2 million in royalty revenues from our Eurodollar contracts, respectively. Prior to 
2010, we did not have any foreign currency exchange contracts. 

The following table presents the quarterly, five-day average U.S. dollar per Eurodollar exchange rate for quarterly 
royalty payments received in each of the years ended December 31, 2011, 2010 and 2009:

For the year ended December 31, 2011, compared to December 31, 2010 

The decrease in operating expenses was primarily driven by reduced legal fees with the resolution of the MedImmune 
litigation and the UCB interference proceedings. 

For the year ended December 31, 2010, compared to December 31, 2009 

The increase in operating expenses was primarily driven by our $92.5 million legal settlement with MedImmune as well 
as increases in other legal related fees, professional services expense and compensation expense. The increase in 
professional services expense is due to costs associated with the implementation of a global royalty audit program, tax 
consultation and the preparation of long term sales and royalty forecasts by outside consultants. Compensation expense 
increased primarily as a result of filling staff positions which were vacant in the first half of 2009.

For the year ended December 31, 2011, compared to December 31, 2010 

Non-operating expense, net, decreased primarily due to lower costs related to our convertible note retirement and 
conversions and lower interest as a result of our $110.9 million reduction in the principal balance of our Non-recourse 
Notes. 

For the year ended December 31, 2010, compared to December 31, 2009 

Non-operating expense, net, increased $43.9 million due primarily to an increase of $24.2 million in interest expense 
with the issuance of $300.0 million of our subsidiary’s Non-recourse Notes in November 2009 that bear interest at 
10.25% per annum. Additionally, the loss on retirement or conversion of convertible notes was $19.2 million higher than 
the prior year primarily due to the exchange and retirement transactions on our 2023 Notes. 

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 operating income. Income tax expense for the year ended December 31, 2010, 
was $58.5 million, which resulted primarily from applying the federal statutory income tax rate to operating income and 
adjusting for a portion of the loss on the retirement or conversion of our 2023 Notes that was not tax deductible. Income 
tax expense for the year ended December 31, 2009, was $90.6 million, which resulted primarily from applying the 
federal statutory income tax rate to operating income less an adjustment to re-establish net operating loss carryforwards 
and certain other adjustments. We no longer pay state income taxes because we moved our operations from California to 
Nevada in December 2008 and Nevada does not impose a corporate income tax. 

During the year ended December 31, 2011, we recorded a $0.5 million increase in our liability for interest and penalties 
associated with uncertain tax positions. The future impact of the unrecognized tax benefit of $23.6 million, if recognized, 
comprises $12.7 million which would affect the effective tax rate and $10.9 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 $0.5 million during the year ended December 31, 2011, and decreased income tax 
expense by $26,000, and $0.4 million during the years ended December 31, 2010 and 2009, respectively. Although the 
timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon 
resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year, we 
do not anticipate any material change to the amount of our unrecognized tax benefit over the next 12 months. 

As of December 31, 2011, we had deferred tax assets in excess of our deferred tax liabilities of approximately 
$21.5 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, 2011, we had a valuation allowance of $10.9 million, primarily related to net 
operating loss carry forwards and research and development tax credits.

Non-GAAP Net Income per Share 

We are presenting net income per share in conformance with GAAP and also on a non-GAAP basis for the years ended 
December 31, 2011, 2010 and 2009, because we believe that this non-GAAP information gives investors an additional 
way to review profitability taken in conjunction with the Company’s GAAP financial statements. For example, we had a 
significant litigation settlement in 2010 and convertible debt retirements and conversions in the three years presented that 
affect comparability between the years. We do not use these non-GAAP measures for any other purpose, such as 
compensation determination. Non-GAAP financial information is not prepared under a comprehensive set of accounting 
rules and should only be used to supplement an understanding of the Company’s net income as reported under GAAP. 
The effect of the non-GAAP adjustments to net income per share: 

(cid:3) 

(cid:3) 

Increases net income per diluted share from $1.15 to $1.17 for the year ended December 31, 2011; 

Increases net income per diluted share from $0.54 to $0.97 for the year ended December 31, 2010; and 

(cid:3)  Decreases net income per diluted share from $1.07 to $1.06 for the year ended December 31, 2009. 

The adjustments comprise: 

For the year ended December 31, 2011, we redeemed $133.5 million in aggregate principal of our 2012 Notes, at a 
redemption price of 100.29% of face value for aggregate consideration of $133.9 million plus interest of $1.0 million. 
This transaction resulted in a charge to non-operating expense, net, of $0.8 million, or $0.5 million net of tax. 
Additionally, in May 2011, we issued our May 2015 Notes, which in accordance with the accounting guidance for 
convertible debt instruments that may be settled in cash or other assets on conversion, required us to separately account 
for the liability component of the instrument in a manner that reflects the market interest rate for a similar nonconvertible 
instrument at the date of issuance. As a result, we separated the principal balance of our May 2015 Notes between the 
fair value of the debt component and the common stock conversion feature. Using an assumed borrowing rate of 7.5%, 
which represents the estimated market interest rate for a similar nonconvertible instrument available to us on the date of 
issuance, we recorded a total debt discount of $18.9 million, allocated $12.3 million to additional paid-in capital and $6.6 
million to deferred tax liability. For the year ended December 31, 2011, the additional interest expense attributable to 
using an implied borrowing rate of 7.5% rather than the stated coupon rate of 3.75% was $2.6 million, or $1.7 million 
net of tax. 

For the year ended December 31, 2010, we recorded a $92.5 million, $60.1 million, net of tax, legal settlement related to 
a definitive settlement agreement with MedImmune. In addition, to limit the further dilution from our 2023 Notes, we 
exchanged an aggregate $61.6 million principal value of our 2023 Notes in privately negotiated transactions with 
institutional holders for consideration consisting of the issuance of the number of shares of common stock convertible 
per the terms of our 2023 Notes plus three additional shares per $1,000 in principal for a total of 11.1 million shares. 
This exchange resulted in a charge to non-operating expense, net, of $1.2 million plus transaction fees of $1.2 million for 
an aggregate charge of $2.4 million which is not deductible for income tax purposes. We also repurchased at market 
prices an aggregate $84.2 million principal value of our 2023 Notes at an average premium of 19% to principal value for 
total consideration of $100.4 million in cash, plus accrued interest. Additionally, we exchanged $92.0 million in 
aggregate principal of our 2012 Notes for February 2015 Notes. In the aggregate, these transactions resulted in a charge 
to non-operating expense, net, of $17.6 million, $16.4 million net of tax.

During the year ended December 31, 2009, we repurchased $22.0 million principal value of our 2012 Notes, in two 
separate transactions, at a combined discount of approximately a 4.8% discount to principal value for total consideration 
of $21.0 million in cash plus accrued interest. We also repurchased $50.0 million principal value of our 2023 Notes at 
approximately a 2% discount to principal value for total consideration of $49.0 million in cash, plus accrued interest. In 
the aggregate, these transactions resulted in a gain of $1.5 million, $0.9 million net of tax. 

Excluding the gain (loss) on the retirement or conversion of convertible notes, the non-cash interest expense on our May

Liquidity and Capital Resources 

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

We had cash, cash equivalents and investments in the aggregate of $227.9 million and $248.2 million at December 31, 
2011 and 2010, respectively. The $20.3 million decrease was primarily attributable to payment of dividends of $83.8 
million, repurchase of convertible notes of $133.9 million, including the $0.4 million incentive, repayment of our Non-
recourse Notes of $110.9 million, and purchase of call options, including legal fees, of $20.8 million, offset by net cash 
provided by operating activities of $169.8 million, net proceeds from the issuance of our May 2015 Notes of $149.7 
million and $10.9 million from the issuance of warrants. 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 expire in December 2014, with the obligation to pay royalties 
under various license agreements expiring sometime thereafter, and we do not expect to receive any meaningful revenue 
from the inventories produced prior to the expiration of our Queen et al. patents beyond the first quarter of 2016. As

such, we are pursuing the acquisition of new royalty generating assets if such royalty assets can be acquired on terms that 
allow us to increase the return to stockholders. 

We continuously evaluate alternatives to increase return for our stockholders, for example, purchasing royalty generating 
assets, buying back our convertible notes, repurchasing our common stock, selling the Company and paying dividends. 
On January 18, 2012, our board of directors declared regular quarterly dividends of $0.15 per share of common stock, 
payable 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. 

Convertible Notes 

May 2015 Notes 

In May 2011, we issued May 2015 Notes, with a principal amount of $155.3 million. Our May 2015 Notes are due May 
1, 2015, and are convertible into 135.9607 shares of the Company’s common stock per $1,000 of principal amount, or 
approximately $7.36 per share, subject to further adjustment upon certain events including dividend payments. 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. 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: 

(cid:3)(cid:4)(cid:4)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; 

(cid:3)(cid:4)(cid:4)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; 

(cid:3)(cid:4)(cid:4)Upon the occurrence of specified corporate events as described further in the indenture; or 

(cid:3)(cid:4)(cid:4)At any time on or after November 1, 2014. 

If a conversion occurs, to the extent that the conversion value exceeds the principal amount, the principal amount is due 
in cash and the difference between the conversion value and the principal amount is due in shares of the Company’s 
common stock. 

In connection with the issuance of our May 2015 Notes, we entered into purchased call option transactions with two 
hedge counterparties entitling the Company to initially purchase up to 19.6 million shares of the Company’s common 
stock. In addition, we sold to the hedge counterparties warrants exercisable, on a cashless basis, for up to 27.5 million 
shares of the Company’s common stock. 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 
$7.36 and $8.65, subject to further adjustment upon certain events including dividend payments, for the purchased call 
options and warrants, respectively. 

If the share price is above $7.36, 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 $8.65, 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 $8.65. For example, a 
10% increase in the share price above $8.65 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, 2011, the if-converted amount of 

33 

 
  
  
  
  
  
  
  
 
  
 
 
 
our May 2015 Notes was less than the principal amount. Therefore, no purchased call options or warrants were exercised 
at December 31, 2011. 

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, 2011. 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 were recorded 
as adjustments to additional paid-in capital. Subsequent changes in fair value will not be recognized as long as the 
purchased call options and warrants continue to meet the criteria for equity classification. As of December 31, 2011, 
$155.3 million of our May 2015 Notes were outstanding. 

Purchased Call Options 

We paid an aggregate amount of $20.8 million to two hedge counterparties, 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 21.1 million shares of our common stock at a strike price of approximately $7.36, which 
corresponds to the conversion price of our May 2015 Notes. We may exercise the purchased call options upon 
conversion of our May 2015 Notes and require the hedge counterparty to deliver shares to the Company in an amount 
equal to the shares required to be delivered by the Company to the note holder for the excess conversion value. The 
purchased call options expire on May 1, 2015, or the last day any of our May 2015 Notes remain outstanding. 

Warrants 

We received an aggregate amount of $10.9 million from the two hedge counterparties for the sale of rights to receive up 
to 27.5 million shares of common stock underlying our May 2015 Notes, at a current strike price of approximately $8.65 
per share, subject to additional anti-dilution and certain other customary adjustments. 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 volume weighted average share price (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. 

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. As part of the transaction, the Company also placed an 
additional $88.0 million in aggregate principal of our February 2015 Notes. Our February 2015 Notes are due 
February 15, 2015, and are convertible at any time, at the holders’ option, into our common stock at a conversion price 
of 155.396 shares of common stock per $1,000 principal amount or $6.44 per share of common stock, subject to further 
adjustment in certain events including dividend payments. Interest on our February 2015 Notes is payable semiannually 
in arrears on February 15 and August 15 of each year. Our February 2015 Notes are senior unsecured debt and are 
redeemable by us in whole or in part on or after August 15, 2014, at 100% of principal amount. Our February 2015 
Notes are not puttable by the note holders other than in the context of a fundamental change resulting in the 
reclassification, conversion, exchange or cancellation of our common stock. Such repurchase event or fundamental 
change is generally defined to include a merger involving PDL, an acquisition of a majority of PDL’s outstanding 
common stock and a change of a majority of PDL’s board of directors without the approval of the board of directors. The 
issuance of our February 2015 Notes was not registered under the Securities Act of 1933, as amended, in reliance on 
exemption from registration thereunder. As of December 31, 2011, $180.0 million of our February 2015 Notes were 
outstanding. 

Series 2012 Notes 

In January 2012, we completed an exchange transaction where we exchanged and subsequently retired approximately 
$169.0 million aggregate principal amount, representing approximately 93.9%, of our February 2015 Notes, for 
approximately $169.0 million aggregate principal amount of new Series 2012 Notes, plus a cash payment of $5.00 for 
each $1,000 principal amount tendered for a total cash incentive payment of approximately $0.8 million. In February 
2012, we entered into separate privately negotiated exchange agreements under which we retired an additional $10.0 
million aggregate principal amount of our February 2015 Notes for $10.0 million aggregate principal amount of our 

34 

 
 
 
 
  
 
  
  
  
  
Series 2012 Notes. Following settlement of the private exchanges on February 2, 2012, $1.0 million of our February 
2015 Notes and $179.0 million of our Series 2012 Notes were outstanding. Like our May 2015 Notes, our Series 2012 
Notes net share settle. 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. 

Our Series 2012 Notes bear interest at a rate of 2.875% per annum, payable semiannually in arrears on February 15 and 
August 15 of each year, beginning on February 15, 2012. The initial conversion rate for our Series 2012 Notes is 
155.396 shares of the Company’s common stock per $1,000 principal amount, which is equivalent to an initial 
conversion price of approximately $6.44 per share of common stock. Upon conversion of Series 2012 Notes, the 
Company will be required to pay cash and, if applicable, deliver shares of the Company’s common stock. 

The terms of our Series 2012 Notes are governed by the Indenture, dated as of January 5, 2012, between the Company 
and The Bank of New York Mellon Trust Company, N.A. A summary of the terms of our Series 2012 Notes is contained 
in, and a copy of the governing Indenture has been filed as an exhibit to, the Company’s Current Report on Form 8-K 
filed with the Securities and Exchange Commission on January 6, 2012. 

Non-recourse Notes 

In November 2009, we completed a $300 million securitization transaction in which we monetized 60% of the net 
present value of the estimated five year royalties (the Genentech 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 Non-recourse Notes due March 15, 2015, bear 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. The Genentech Royalties and other payments, if any, that QHP is entitled to receive under the 
agreements with Genentech, together with any funds made available from certain accounts of QHP, are the sole source of 
payment of principal and interest on our Non-recourse Notes, which are secured by a continuing security interest granted 
by QHP in its rights to receive the Genentech Royalties. Our Non-recourse Notes may be redeemed at any time prior to 
maturity, in whole or in part, at the option of QHP at a make-whole redemption price. The amount of quarterly 
repayment of the principal of our Non-recourse Notes will vary based upon the amount of future quarterly Genentech 
Royalties received. As of December 31, 2011, $93.4 million in aggregate principal of our Non-recourse Notes was 
outstanding. The anticipated final repayment date of our Non-recourse Notes is September 2012. 

2012 Notes Retirement 

In February 2005, we issued our 2012 Notes due February 15, 2012, with a principal amount of $250.0 million. In 2009, 
we repurchased $22.0 million in aggregate face value of our 2012 Notes, at an average discount of 4.8% from face value 
in open market transactions for aggregate consideration of $21.0 million in cash, plus accrued but unpaid interest. In 
November 2010, we exchanged $92.0 million 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 new February 2015 Notes. In December 2010, we repurchased $2.5 million of 2012 Notes in the open 
market at a discount of 0.5% to principal value, for aggregate consideration of $2.5 million in cash, plus accrued but 
unpaid interest. In June 2011, we redeemed the final $133.5 million aggregate principal outstanding for aggregate 
consideration of $133.9 million plus $1.0 million interest. As of December 31, 2011, our 2012 Notes were fully retired. 

2023 Notes Retirement 

In July 2003, we issued our 2023 Notes due August 16, 2023, with a principal amount of $250.0 million. In 2009, we 
repurchased an aggregate of $50.0 million principal value of our 2023 Notes, at a discount of 2.0% from principal value 
in open market transactions for aggregate consideration of $49.0 million in cash, plus accrued interest. During the three 
months ended June 30, 2010, we repurchased an aggregate of $84.2 million principal value of our 2023 Notes, in the 
open market at a premium of 19% to principal value for aggregate consideration of $100.4 million in cash, plus accrued 
interest. In August 2010, we exchanged an aggregate of $61.6 million principal value of our 2023 Notes in privately 
negotiated transactions with institutional holders for consideration consisting of the issuance of the number of shares of 
common stock convertible per the terms of our 2023 Notes plus three additional shares per $1,000 in principal for a total 
of 11.1 million shares. Subsequent to the exchange transaction, we issued a redemption notice for the remaining principal 
outstanding after the exchange transaction of $54.3 million. Under the redemption notice, $50.1 million of the 
outstanding principal was converted to 8.9 million shares of common stock and $4.2 million was redeemed for cash. As 
of December 31, 2010, our 2023 Notes were fully retired.

Contractual Obligations 

As of December 31, 2011, our contractual obligations consisted primarily of our May 2015 Notes, our February 2015 
Notes and our Non-recourse Notes, which in the aggregate totaled $428.6 million in principal. Our May 2015 Notes and 
our February 2015 Notes are not puttable by the note holders other than in the context of a fundamental change. 

In January 2012, we completed an exchange transaction where we exchanged and subsequently retired approximately 
$169.0 million aggregate principal amount, representing approximately 93.9%, of our February 2015 Notes, for 
approximately $169.0 million aggregate principal amount of new Series 2012 Notes. Additionally, 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. Following settlement of the private exchanges on February 2, 2012, $1.0 million of our February 2015 Notes and 
$179.0 million of our Series 2012 Notes were outstanding. Like our May 2015 Notes, our Series 2012 Notes net share 
settle. 

We expect that our debt service obligations over the next several years will consist of interest payments and repayment 
of our May 2015 Notes, our February 2015 Notes and our Series 2012 Notes. Also our debt service obligations in 2012 
include our Non-recourse-Notes, which we expect will be fully retired in the third quarter of 2012. 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.

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. As of December 31, 2011, the total 
lease payments for the duration of the guarantee, which runs through December 2021, are approximately $110.8 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. In April 2010, Abbott Laboratories 
acquired Facet and later renamed the company Abbott Biotherapeutics Corp. We have recorded a liability of $10.7 
million on our Consolidated Balance Sheets as of December 31, 2011, and 2010, related to this guarantee.

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, 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 Eurodollar risk exposures related to our licensees’ product sales with Eurodollar contracts. In general, these 
contracts are intended to offset the underlying Eurodollar market risk in our royalty revenues. In January and May 2010, 
we entered into a series of Eurodollar contracts covering the quarters in which our licensees’ sales occur through 
December 2012. We did not have Eurodollar contracts prior to 2010. We have designated the Eurodollar contracts as 
cash flow hedges. At the inception of the hedging relationship and on a quarterly basis, we assess hedge effectiveness. 
The aggregate unrealized gain or loss on the effective component of our Eurodollar contracts, net of estimated taxes, is 
recorded in stockholders’ deficit as accumulated other comprehensive income (loss). Gains or losses on cash flow hedges 
are recognized as royalty revenue in the same period that the hedged transaction, royalty revenue, impacts earnings. The 
following table summarizes the notional amounts, Eurodollar exchange rates and fair values of our outstanding 
Eurodollar contracts designated as hedges at December 31, 2011 and 2010:

On January, 26, 2012, we restructured our 2012 Eurodollar option contract into a forward contract, which allowed us to 
hedge our royalties at a rate more favorable than the rate that was insured by the option contract. With the restructure, we 
were able to improve the minimum rate at which we will recognize hedged Euro based royalties for 2012 by $0.03 (from 
$1.20 to $1.23). On the same date we executed new forward contracts to hedge our 2013 Euro based royalties. For the 
projected 2013 royalties hedged, we will recognize revenue at $1.30.

Interest Rate Risk 

Our investment portfolio was approximately $224.8 million at December 31, 2011, and $242.5 million at December 31, 
2010, and consisted of investments in Rule 2a-7 money market funds, corporate debt securities, commercial paper, U.S. 
government sponsored agency bonds and U.S. treasury securities. 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 $347.6 million at December 31, 2011 and $324.4 
million at December 31, 2010, based on available pricing information. At December 31, 2011, our convertible notes 
consisted of our May 2015 Notes, with a fixed interest rate of 3.75% and our February 2015 Notes, with a fixed interest 
rate of 2.875%. At December 31, 2010, our convertible notes consisted of our 2012 Notes, with a fixed interest rate of 
2.00% 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 aggregate fair value of our Non-recourse Notes was estimated to be $95.2 million at December 31, 2011, and $208.4 
million at December 31, 2010, based on available pricing information. Our Non-recourse Notes bear interest at a fixed 
rate of 10.25% per annum. This obligation is subject to interest rate risk because the fixed interest rates under this 
obligation may exceed current interest rates. 

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 note holders may put the debt to us. Our convertible notes may be 
converted to common stock prior to the maturity date.

The fair value of the remaining payments under our convertible notes was estimated based on the trading value of 
these notes at December 31, 2011. 

The fair value of our Non-recourse Notes at December 31, 2011, was estimated based on the trading value of the 
Non-recourse notes at December 31, 2011. Repayment of our Non-recourse Notes is based on anticipated future 
royalties to be received from Genentech and the anticipated final payment date is September 2012.

PDL BIOPHARMA, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

December 31, 2011 

1. Organization and Business 

PDL BioPharma Inc. (we, us, our, PDL and the Company) pioneered humanization of monoclonal antibodies and, by 
doing so, enabled the discovery of a new generation of targeted treatments for cancer and immunologic diseases. Today, 
PDL is focused on intellectual property asset management, investing in new royalty bearing assets and maximizing the 
value of its patent portfolio and related assets. We receive royalties based on sales of humanized antibody products 
marketed today and may also receive royalty payments on additional humanized antibody products launched before final 
patent expiry in December 2014. Under most of our licensing agreements, we are entitled to receive a flat-rate or tiered 
royalty based upon our licensees’ net sales of covered antibodies. We have also entered into licensing agreements under 
which we have licensed certain rights for development stage products that have not yet reached commercialization 
including products that are currently in Phase 3 clinical trials. 

In the year ended December 31, 2011, we received royalties on sales of the seven humanized antibody products listed 
below, all of which are currently approved for use by the U.S. Food and Drug Administration (FDA) and other 
regulatory agencies outside the United States. In the years ended December 31, 2011, 2010 and 2009, we received 
approximately $351.6 million, $343.5 million and $305.0 million, respectively, of royalty revenues under license 
agreements.

Wyeth Pharmaceuticals, Inc. (Wyeth) ……..      Mylotarg® 

Chugai Pharmaceutical Co., Ltd. (Chugai) ...     Actemra® 

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 (the Spin-Off) to Facet Biotech Corporation (Facet). In April 2010, 
Abbott Laboratories (Abbott) acquired Facet and later renamed the company Abbott Biotherapeutics Corp. 

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 (GAAP) and under the rules and regulations of the Securities and Exchange Commission (SEC). 

Principles of Consolidation 

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, QHP 
Royalty Sub LLC (QHP). All material intercompany balances and transactions are eliminated in consolidation. We 
prepare our consolidated financial statements in accordance with the SEC and GAAP and include all adjustments of a 
normal recurring nature that are necessary to fairly present our consolidated results of operations, financial position and 
cash flows for all periods presented. 

44 

 
  
  
  
  
  
  
  
  
  
    
  
  
    
  
  
    
  
  
  
  
  
  
  
  
  
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 

We are required to report operating segments and make related disclosures about our products, services, geographic areas 
and major customers. 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 or aggregate basis. As of December 31, 2011, we operated as one segment. Our operations and facilities are located 
in Incline Village, Nevada. 

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, cash equivalents and investments with high credit quality financial institutions and in 
U.S. government securities, U.S. government agency securities and investment grade corporate debt securities 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 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. As of December 31, 2011 and 2010, we had no Level 3 assets or liabilities. 

We do not estimate the fair value of our royalty assets for financial statement reporting purposes. 

Foreign Currency Hedging 

We hedge certain Eurodollar currency exposures related to our licensees’ product sales with Eurodollar forward 
contracts and Eurodollar option contracts (collectively, Eurodollar contracts). In general, these contracts are intended to 
offset the underlying Eurodollar market risk in our royalty revenues. Our exposure to credit risk from these contracts is a 
function of foreign currency exchange rates and, therefore, varies over time. We transact with major banks to limit the 
credit risk that our counterparty may be unable to perform and monitor the exposure in the context of current market 
conditions. We mitigate the risk of loss by entering into a netting agreement with our counterparty that provides for 
aggregate net settlement of all of the Eurodollar contracts should our counterparty default on the contracts prior to 
contract settlement. Therefore, our overall risk of loss in the event of counterparty default is limited to the net amount of 
any unrecognized gains or losses on outstanding contracts at the date of default. We do not enter into speculative foreign 
currency transactions. We have designated the Eurodollar contracts as cash flow hedges. At the inception of the hedging 
relationship and on a quarterly basis, we assess hedge effectiveness. The aggregate unrealized gain or loss on the 
effective component of our Eurodollar contracts, net of estimated taxes, is recorded in stockholders’ deficit as 
accumulated other comprehensive income (loss). Gains or losses on cash flow hedges are recognized as royalty revenue 
in the same period that the hedged transaction, royalty revenue, impacts earnings.

Revenue Recognition 

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 minimal 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. 

Comprehensive Income (Loss) 

Comprehensive income (loss) comprises net income adjusted for other comprehensive income (loss), which includes the 
changes in unrealized gains and losses on Eurodollar contracts and changes in unrealized gains and losses on our 
investments in available-for-sale securities, if any, which are excluded from our net income. The components and 
accumulated balances of comprehensive income (loss) were:  

(cid:3)(cid:4)(cid:4)Unrealized gains and losses on cash flow hedges, net of tax, were $(1.9) million at December 31, 2011, $3.2 

million at December 31, 2010, and zero at December 31, 2009. 

(cid:3)(cid:4)(cid:4)Unrealized gains and losses on investments in available-for-sale securities, net of tax, were $29,000 at 

December 31, 2011, $(1,000) at December 31, 2010, and zero at December 31, 2009. 

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 …….  3 years 
Furniture and fixtures ……………….  7 years 

Recent Accounting Pronouncements 

In June 2011, the Financial Accounting Standards Board (FASB) issued accounting standard update (ASU) 2011-05, 
eliminating the option to present the components of other comprehensive income as part of the statement of changes in 
stockholders’ equity. The update requires presentation for items of net income and other comprehensive income either in 
one continuous statement or in two separate, but consecutive, statements. Additionally, this ASU includes a new 
requirement to show reclassification adjustments from other comprehensive income to net income on the face of the 
statement. Except for, the new requirement to show reclassification adjustments from other comprehensive income to 
income on the face of the income statement, this guidance is required for our first quarter of 2012 with retrospective 
application also required. We do not expect this guidance to have a material impact on our financial statements. 

3. Net Income per Share 

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

We compute net income per diluted share using the sum of the weighted-average number of common and common 
equivalent shares outstanding. Common equivalent shares used in the computation of net income per diluted share 
include shares that may be issued under our stock options and restricted stock awards, our 2.00% Convertible Senior

Notes), and our 2.75% Convertible Subordinated Notes due August 16, 2023 (2023 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. Our 2023 Notes were fully retired as of September 14, 2010. Our 2012 Notes were 
fully retired as of June 30, 2011.

We excluded 0.2 million, 0.3 million, and 2.5 million of outstanding stock options from our net income per diluted share 
calculations for the years ended December 31, 2011, 2010 and 2009, respectively, because the option exercise prices 
were greater than the average market prices of our common stock during these periods; therefore, their effect was anti-
dilutive. 

In May 2011, we issued 3.75% Senior Convertible Notes due May 1, 2015 (May 2015 Notes). If converted, the principal 
amount of our May 2015 Notes will be settled in cash and the difference between the conversion value and the principal 
amounts will be settled in shares of the Company’s common stock. For the year ended December 31, 2011, we excluded 
a weighted average of 13.3 million shares of potential dilution for our May 2015 Notes and a weighted average of 13.3 
million shares of potential dilution for our warrants because the conversion price and exercise price exceeded the average 
market price of our common stock and were therefore anti-dilutive. These securities could be dilutive in future periods. 
In addition, we excluded a weighted average of (13.3) million shares for our purchased call options because they will 
always be anti-dilutive, therefore, will have no effect on diluted net income per share. 

For information related to the conversion rates on our convertible debt, see Note 12.

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. 

Corporate debt securities consist primarily of U.S. Corporate bonds. The fair value of corporate debt securities is 
estimated using recently executed transactions or market quoted prices, where observable. Independent pricing sources 
are also used for valuation. No corporate debt securities had been moved from Level 1 inputs to Level 2 inputs at 
December 31, 2011, as compared to December 31, 2010. 

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

We do not estimate the fair value of our royalty assets for financial statement reporting purposes. 

5. Cash Equivalents and Investments 

As of December 31, 2011 and 2010, we had invested our excess cash balances primarily in money market funds, 
corporate debt securities, commercial paper, U.S. government sponsored agency bonds and U.S. treasury securities. Our 
securities are classified as available-for-sale and are carried at estimated fair value, with unrealized gains and losses 
reported in accumulated other comprehensive income (loss) in stockholders’ 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.

The unrealized loss on investments included in other comprehensive income (loss), net of estimated taxes, was 
approximately $29,000 as of December 31, 2011, and $1,000 as of December 31, 2010. No significant facts or 
circumstances have arisen to indicate that there has been any deterioration in the creditworthiness of the issuers of these 
securities. Based on our review of these securities, we believe we had no other-than-temporary impairments on these 
securities as of December 31, 2011, because we do not intend to sell these securities and it is more likely than not that we 
will hold these securities until the recovery of their amortized cost basis. 

6. Foreign Currency Hedging 

Our licensees operate in foreign countries, which exposes us to market risk associated with foreign currency exchange 
rate fluctuations between the U.S. dollar and other currencies, primarily the Eurodollar. In order to manage the risk 
related to changes in foreign currency exchange rates, we entered into a series of Eurodollar contracts covering the 
quarters in which our licensees’ sales occur through December 2012. Our Eurodollar contracts used to hedge royalty 
revenues based on underlying Eurodollar sales are designated as cash flow hedges.

Eurodollar 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, 2011, the unrealized net loss on the effective component of our 
Eurodollar contracts included in other comprehensive income (loss), net of estimated taxes, was $(1.9) million. As of 
December 31, 2010, the unrealized net gain on the effective component of our Eurodollar contracts included in other 
comprehensive income (loss), net of estimated taxes, was $3.2 million. There ineffective component of our foreign 
currency exchange contracts for the year ended December 31, 2011, was $18,874 and there was no ineffectiveness for 
the year ended December 30, 2010. 

For the years ended December 31, 2011 and 2010, we recognized $1.0 million and $5.2 million in royalty revenues from 
foreign currency exchange contracts, respectively. Approximately $1.2 million, net of tax, is expected to be reclassified 
from other comprehensive income (loss) against earnings in the next 12 months. We did not have foreign currency 
exchange contracts prior to 2010.

Operating Leases 

Current Facilities and Equipment 

We currently occupy a leased facility in Incline Village, Nevada, with a lease term through May 2012. We also lease 
certain office equipment under operating leases. Rental expense under these arrangements totaled $0.2 million, 
$0.1 million and $0.2 million for the years ended December 31, 2011, 2010 and 2009.

Contingencies 

As permitted under Delaware law, under the terms of our bylaws, we have agreed to indemnify our directors and officers 
and, under the terms of indemnification agreements we have entered into, we have agreed to indemnify our executive 
officers and directors for certain events or occurrences, subject to certain limits, while the officer or director is or was 
serving as an officer or director of the Company. 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. We believe the fair value of these indemnification agreements and bylaw provisions 
is minimal and, accordingly, we have not recorded the fair value liability associated with these agreements as of 
December 31, 2011 and 2010.

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 are 
convertible into 135.9607 shares of the Company’s common stock per $1,000 of principal amount, or approximately 
$7.36 per share, subject to further adjustment upon certain events including dividend payments. 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: 

(cid:3)(cid:4)(cid:4)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; 

52 

 
  
    
  
  
  
  
  
  
 
   
   
    
   
 
  
   
      
      
       
      
  
 
  
  
 
  
  
(cid:3)(cid:4)(cid:4)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;  

(cid:3)(cid:4)(cid:4)Upon the occurrence of specified corporate events as described further in the indenture; or 

(cid:3)(cid:4)(cid:4)At any time on or after November 1, 2014. 

If a conversion occurs, to the extent that the conversion value exceeds the principal amount, the principal amount is due 
in cash and the difference between the conversion value and the principal amount is due in shares of the Company’s 
common stock. As of December 31, 2011, the if-converted amount of our May 2015 Notes was less than the principal 
amount. 

In accordance with the accounting guidance for convertible debt instruments that may be settled in cash or other assets 
on conversion, we were required to separately account for the liability component of the instrument in a manner that 
reflects the market interest rate for a similar nonconvertible instrument at the date of issuance. As a result, we separated 
the principal balance of our May 2015 Notes between the fair value of the debt component and the fair value of the 
common stock conversion feature. Using an assumed borrowing rate of 7.5%, which represents the estimated market 
interest rate for a similar nonconvertible instrument available to us on the date of issuance, we recorded a total debt 
discount of $18.9 million, allocated $12.3 million to additional paid-in capital and $6.6 million to deferred tax liability. 
The discount is being amortized to interest expense over the term of our May 2015 Notes and increases interest expense 
during the term of our May 2015 Notes from the 3.75% cash coupon interest rate to an effective interest rate of 7.5%. As 
of December 31, 2011, the remaining discount amortization period is 3.3 years.

In connection with the issuance of our May 2015 Notes, we entered into purchased call option transactions with two 
hedge counterparties entitling the Company to initially purchase up to 19.6 million shares of the Company’s common 
stock. In addition, we sold to the hedge counterparties warrants exercisable, on a cashless basis, for up to 27.5 million 
shares of the Company’s common stock. 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 
$7.36 and $8.65, subject to further adjustment upon certain events including dividend payments, for the purchased call 
options and warrants, respectively. 

If the share price is above $7.36, 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 $8.65, 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 $8.65. For example, a 

53 

 
 
  
 
  
 
 
 
 
 
  
  
  
 
 
 
 
  
 
10% increase in the share price above $8.65 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, 2011, the market price condition 
for convertibility of our May 2015 Notes was not met and there were no related purchased call options or warrants 
exercised. 

The purchased call options and warrants are considered indexed to PDL stock, require net-share settlement, and met all 
criteria for equity classification at inception and at December 31, 2011. 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 were recorded 
as adjustments to additional paid-in capital. Subsequent changes in fair value will not be recognized as long as the 
purchased call options and warrants continue to meet the criteria for equity classification. 

Purchased Call Options 

We paid an aggregate amount of $20.8 million to two hedge counterparties, 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 21.1 million shares of our common stock at a strike price of approximately $7.36, which 
corresponds to the conversion price of our May 2015 Notes. We may exercise the purchased call options upon 
conversion of our May 2015 Notes and require the hedge counterparty to deliver shares to the Company in an amount 
equal to the shares required to be delivered by the Company to the note holder for the excess conversion value. The 
purchased call options expire on May 1, 2015, or the last day any of our May 2015 Notes remain outstanding. 

Warrants 

We received an aggregate amount of $10.9 million from the two hedge counterparties for the sale of rights to receive up 
to 27.5 million shares of common stock underlying our May 2015 Notes, at a current strike price of approximately $8.65 
per share, subject to additional anti-dilution and certain other customary adjustments. 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 volume weighted average share price of our common stock, as defined in the warrants (VWAP), 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. 

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. Our February 
2015 Notes are due February 15, 2015, and are convertible at any time, at the holders’ option, into our common stock at 
a conversion price of 155.396 shares of common stock per $1,000 principal amount, or $6.44 per share, subject to further 
adjustment in certain events including dividend payments. We pay interest on our February 2015 Notes semiannually in 
arrears on February 15 and August 15 of each year. Our February 2015 Notes are senior unsecured debt and are 
redeemable by us in whole or in part on or after August 15, 2014, at 100% of principal amount. Our February 2015 
Notes are not puttable by the note holders other than in the context of a fundamental change resulting in the 
reclassification, conversion, exchange or cancellation of our common stock. Such repurchase event or fundamental 
change is generally defined to include a merger involving PDL, an acquisition of a majority of PDL’s outstanding 
common stock and a change of a majority of PDL’s board of directors without the approval of the board of directors. Our 
February 2015 Notes issuance was not registered under the Securities Act of 1933, as amended, in reliance on exemption 
from registration thereunder. As of December 31, 2011, our February 2015 Notes aggregate principal outstanding was 
$180.0 million. 

54 

 
  
  
 
 
 
 
  
  
  
As of December 31, 2011, our February 2015 Notes unamortized issuance costs, included as a component of Other assets 
on the Consolidated Balance Sheets, were $3.2 million. As of December 31, 2011, the unamortized discount on our 
February 2015 Notes was $2.3 million. The issuance cost and discount are being amortized to interest expense over the 
term of our February 2015 Notes, with a remaining amortization period of approximately 3.2 years. 

In January and February 2012, we completed exchange transactions where we exchanged our February 2015 Notes for 
our new 2.875% Series 2012 Convertible Senior Notes due February 15, 2015 (Series 2012 Notes). For further 
information regarding the Series 2012 Notes, see Note 19. 

2012 Notes Retirement 

Our 2012 Notes of $133.5 million aggregate principal were fully retired at June 30, 2011, at a redemption price of 
100.29% of principal for aggregate consideration of $133.9 million plus interest of $1.0 million. We recorded a net loss 
of $0.8 million from the redemption of the debt. 

In 2010, we exchanged $92.0 million in aggregate principal of our 2012 Notes for February 2015 Notes. In addition, we 
repurchased $2.5 million aggregate principal value of our 2012 Notes at a discount of 0.5% to face value in an open 
market transaction for aggregate consideration of $2.5 million in cash, plus accrued interest. Also in 2010, certain 
holders of the 2012 Notes converted an aggregate of $10,000 principal of our 2010 Notes into 1,283 shares of common 
stock. 

In 2009, the Company repurchased $22.0 million aggregate principal of our 2012 Notes, for aggregate consideration of 
$21.0 million in cash, plus accrued interest. We recorded a net gain of $0.8 million from the redemption of the debt. 

2023 Notes Retirement 

As of December 31, 2010, our 2023 Notes were fully retired. In 2010, $111.7 million aggregate principal of our 2023 
Notes were converted into 20.0 million shares of common stock, and we recorded a $2.4 million loss on the induced 
conversion to shares of common stock. Additionally, $88.4 million aggregate principal of our 2023 Notes were redeemed 
for $104.6 million. In 2009, we repurchased $50.0 million aggregate principal of our 2023 Notes, for aggregate 
consideration of $49.0 million in cash, plus accrued interest and recorded a net gain of $0.7 million. 

Non-recourse Notes 

In November 2009, we completed a $300 million securitization transaction in which we monetized 60% of the net 
present value of the estimated five year royalties from sales of Genentech products (the Genentech Royalties) 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 (Non-recourse Notes) 
bear 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. Once all obligations on 
our Non-recourse Notes have been paid in full, including all other sums payable under the indenture, the indenture shall 
cease to be of further effect and all of the security interests in the collateral shall terminate, including the pledge by PDL 
to the trustee of its equity interest in QHP. At such point, there will be no further restrictions on the Genentech Royalties 
and PDL shall be free to either keep them in QHP, transfer them back to PDL or to further dispose or monetize them. 

The Genentech Royalties and other payments, if any, that QHP will be entitled to receive under the agreements with 
Genentech, together with any funds made available from certain accounts of QHP, will be the sole source of payment of 
principal and interest on our Non-recourse Notes, which will be secured by a continuing security interest granted by 
QHP in its rights to receive payments under such agreements and all of its other assets and a pledge by PDL of its equity 
ownership interest in QHP. Our Non-recourse Notes may be redeemed at any time prior to maturity, in whole or in part, 
at the option of QHP at a make-whole redemption price. As of December 31, 2011, the remaining principal balance was 
$93.4 million, 

As of December 31, 2011, the remaining unamortized issuance costs were $1.2 million, and are included as a component 
of Prepaid and other current assets on the Consolidated Balance Sheets. These costs are being amortized to interest 
expense using the effective interest method over the estimated repayment period, or approximately three years.

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 would be held liable by the landlord as a co-tenant and, thus, we have in 
substance guaranteed the payments under the lease agreements for the Redwood City facilities. As of December 31, 
2011, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately 
$110.8 million. We would also be responsible for lease-related costs including utilities, property taxes and common area 
maintenance which may be as much as the actual lease payments if Facet were to default. In April 2010, Abbott acquired 
Facet and later renamed the company Abbott Biotherapeutics Corp. 

As of December 31, 2011 and 2010, we had a liability of $10.7 million on our Consolidated Balance Sheets for the 
estimated fair value of this guarantee. In future periods, we may increase the recorded liability for this obligation if we 
conclude that a loss, which is larger than the amount recorded, is both probable and estimable. 

14. 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 (APIC) 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 directors and employees for the years ended December 31, 2011, 2010 and 2009, 
was $337,000, $662,000 and $773,000, respectively. 

The stock-based compensation expense related to non-employees for the years ended December 31, 2011, 2010 and 
2009, was $50,000, zero, and $48,000, respectively. 

Stock-Based Incentive Plans 

We currently have one active stock-based incentive plan under which we may grant stock-based awards to our 
employees, directors and consultants. 

The total number of shares of common stock authorized for issuance, shares of common stock issued upon exercise of 
options or grant of restricted stock, shares of common stock subject to outstanding awards and available for grant under

As of December 31, 2011, there were 136,507 shares of unvested restricted stock awards outstanding. 
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.

As of December 31, 2011, the aggregate intrinsic value of our outstanding and exercisable stock options was $45,000 
and the weighted-average remaining contractual life was 2.33 years. The aggregate intrinsic value represents the total 
pre-tax intrinsic value, based on the closing prices of our common stock of $6.20 on December 31, 2011, which would 
have been received by the option holders had option holders exercised their options as of that date. In connection with 
the Spin-Off of Facet in December 2008, we terminated substantially all employees. As a result, approximately 4 million 
options with an average exercise price of $17.96 were forfeited during the year ended December 31, 2009. All stock 
options were fully vested in 2010.

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, and 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 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.

Stock-based compensation expense associated with our restricted stock for the years ended December 31, 2011, 2010 
and 2009, was $0.4 million, $0.6 million and $0.5 million, respectively. As of December 31, 2011, the aggregate 
intrinsic value of non-vested restricted stock was $0.8 million. Total unrecognized compensation costs associated with 
non-vested restricted stock as of December 31, 2011, was $0.5 million, excluding forfeitures, which we expect to 
recognize over a weighted-average period of ten months. 

15. Cash Dividends 

On January 18, 2012, our board of directors declared that the regular quarterly dividends to be paid to our stockholders in 
2012 will be $0.15 per share of common stock, payable 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. 

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 
paid $83.8 million in dividends in 2011. 

In January 2010, our board of directors declared two special cash dividends of $0.50 per share of common stock payable 
on April 1, 2010, and October 1, 2010. We paid $59.9 million to our stockholders on April 1, 2010, and $69.8 million to 
our stockholders on October 1, 2010. As of December 31, 2010, we had $20,000 accrued in other accrued liabilities for 
estimated dividends payable on unvested restricted stock.

Deferred tax assets and liabilities are determined based on the differences between financial reporting and income tax 
bases of assets and liabilities, as well as net operating loss carryforwards and are measured using the enacted tax rates

As of December 31, 2011 and 2010, we had federal net operating loss carryforwards of $42.9 million and $44.7 million, 
respectively. The federal net operating loss carryforwards will expire in the year 2023, if not used. In addition, as we 
moved our entire operations outside of California in 2008, it is unlikely that we will realize any future benefit from any 
state net operating loss and credit carryforwards. The net operating loss carryforwards which resulted from exercises of 
stock options were not recorded on the Consolidated Balance Sheet. Instead, such unrecognized deferred tax benefits 
were accounted for as a credit to additional paid-in capital and were realized through a reduction in taxes payable. 

Use of the federal 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 they are used. We have an annual limitation on the use of our federal 
operating losses of $1.8 million for each of the years ended December 31, 2012 to 2022, and $1.3 million for the year 
ended December 31, 2023. As of December 31, 2011, we estimate that at least $22.0 million of the $42.9 million of 
federal net operating loss carryforwards will expire prior to their use due to change of ownership provisions. 

During the year ended December 31, 2011, we recorded no change in our liability associated with uncertain tax 
positions. A reconciliation of our unrecognized tax benefits, excluding accrued interest and penalties, for 2011 and 2010 
is:

The future impact of the unrecognized tax benefit of $23.1 million, if recognized, is as follows: $12.2 million would 
affect the effective tax rate and $10.9 million 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 income tax expense in the 
Consolidated Statements of Income by $0.5 million during the year ended December 31, 2011, and decreased income tax 
expense by $26,000 and $0.4 million during the years ended December 31, 2010 and 2009, respectively. In general, our 
income tax returns are subject to examination by U.S. federal, state, and local tax authorities for tax years 1995 forward. 
The IRS is currently examining our 2008 tax return. We are also currently under income tax examination in the state of 
California for tax years 2008 and 2009. 

Although the timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if 
any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for 
each year, we do not anticipate any material change to the amount of our unrecognized tax benefits over the next 12 
months. 

18. Legal Proceedings 

Resolution of Challenges against 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, LLC (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 (EPO) relating to the opposition against European Patent No. 0 451 216B 
(the ‘216B Patent) including the opposition owned by BioTransplant Incorporated (BioTransplant).

Settlement with UCB 

On February 2, 2011, we reached a settlement with UCB Pharma S.A. (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 million to PDL and termination of pending patent interference 
proceedings before the U.S. Patent and Trademark office (PTO) involving our U.S. Patent No. 5,585,089 patent (the ‘089 
Patent) and our U.S. Patent No. 6.180.370 (the ‘370 Patent) 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 AG (Novartis). Under the settlement agreement, PDL 
agreed to dismiss its claims against Novartis in its action in Nevada state court which also includes Genentech, Inc. 
(Genentech) and F. Hoffman Roche Ltd (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 cancelled the appeal proceeding and 
terminated the 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, 2011, 
approximately 33% 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 

Communications with Genentech regarding European SPCs 

In August 2010, we received a letter from Genentech, sent on behalf of Roche and Novartis, asserting that Avastin, 
Herceptin, Lucentis and Xolair (the Genentech Products) do not infringe the supplementary protection certificates 
(SPCs) granted to PDL by various countries in Europe for each of the Genentech Products and seeking a response from 
PDL to these assertions. Genentech did not state what actions, if any, it intends to take with respect to its assertions. 
PDL’s SPCs were granted by the relevant national patent offices in Europe and specifically cover the Genentech 
Products. The SPCs covering the Genentech Products effectively extend our European patent protection for the ‘216B 
Patent generally until December 2014, except that the SPCs for Herceptin will generally expire in July 2014. 

Genentech’s letter does not suggest that the Genentech Products do not infringe PDL’s U.S. patents to the extent that 
such Genentech Products are made, used or sold in the United States (U.S.-based Sales). Genentech’s quarterly royalty 
payments received in August and November of 2010 after receipt of the letter included royalties generated on all 
worldwide sales of the Genentech Products. 

If Genentech is successful in asserting this position, then under the terms of our license agreements with Genentech, it 
would not owe us royalties on sales of the Genentech Products that are both manufactured and sold outside of the United 
States. Royalties on sale of the Genentech Products that are made and sold outside of the United States (ex-U.S.-based 
Manufacturing and Sales) accounted for approximately 33% of our royalty revenues for the year ended December 31, 
2011. Based on announcements by Roche regarding moving more manufacturing outside of the United States, we expect 
this amount to increase in the future. 

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

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

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

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

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

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

19. Subsequent Event 

In January 2012, we completed an exchange transaction where we exchanged and subsequently retired approximately 
$169.0 million aggregate principal amount, representing approximately 93.9%, of our 2.875% Convertible Senior Notes 
due February 15, 2015 (February 2015 Notes), for approximately $169.0 million aggregate principal amount of new 
2.875% Series 2012 Convertible Senior Notes due February 15, 2015 (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. Following settlement of the exchanges on February 2, 2012, $1.0 million of our February 2015 Notes 
and $179.0 million of our Series 2012 Notes were outstanding. Like our May 2015 Notes, our Series 2012 Notes net 
share settle. 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. 

Our Series 2012 Notes bear interest at a rate of 2.875% per annum, payable semiannually in arrears on February 15 and 
August 15 of each year, beginning on February 15, 2012. The conversion rate for our new Series 2012 Notes is 155.396 
shares of the Company’s common stock per $1,000 principal amount, which is equivalent to an initial conversion price 
of approximately $6.44 per share of common stock.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Stockholders of PDL BioPharma, Inc. 

We have audited the accompanying consolidated balance sheets of PDL BioPharma, Inc. as of December 31, 2011 and 
2010, and the related consolidated statements of income, cash flows, and stockholders’ equity (deficit) for each of the 
three years in the period ended December 31, 2011. 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, 2011 and 2010, and the consolidated results of its operations and its 
cash flows for each of the three years in the period ended December 31, 2011, 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, 2011, based on criteria established in Internal Control-Integrated Framework issued by the Committee of 
Sponsoring Organizations of the Treadway Commission and our report dated February 23, 2012 expressed an 
unqualified opinion thereon.

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 Vice President of Finance and 
Principal Accounting 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 Vice 
President of Finance and Principal Accounting Officer have concluded that, as of December 31, 2011, 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 
Vice President of Finance and Principal Accounting 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, 2011. 

Changes in Internal Controls 

There were no changes in our internal controls over financial reporting during the quarter ended December 31, 2011 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.

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, 2011, based on 
criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (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, 2011, 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, 2011 and 2010, and the related 
consolidated statements of income, stockholders’ equity (deficit) and cash flows for each of the three years in the period 
ended December 31, 2011 of PDL BioPharma, Inc. and our report dated February 23, 2012 expressed an unqualified 
opinion thereon.
