1. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with GAAP for interim financial information. The financial statements include all adjustments (consisting only of normal recurring adjustments) that management of PDL believes are necessary for a fair presentation of the periods presented. These interim financial results are not necessarily indicative of results expected for the full fiscal year or for any subsequent interim period.

The accompanying Condensed Consolidated Financial Statements and related financial information should be read in conjunction with the audited Consolidated Financial Statements and the related notes thereto for the year ended December 31, 2013, included in our Annual Report on Form 10-K filed with the SEC. The Condensed Consolidated Balance Sheet at December 31, 2013, has been derived from the audited Consolidated Financial Statements at that date.

Principles of Consolidation

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

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Notes Receivable and Other Long-Term Receivables

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

Customer Concentration

The percentage of total revenue recognized, which individually accounted for ten percent or more of our total revenues, was as follows:



		Three Months Ended March 31,
Licensee	Product Name	2014		2013
Genentech	Avastin^®	29	%	36	%
	Herceptin^®	27	%	33	%
	Lucentis^®	12	%	13	%

Biogen Idec¹	Tysabri^®	9	%	14	%

Depomed	Glumetza^®	17	%	0	%

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

Foreign Currency Hedging

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

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

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