Fair Value Measurements [Abstract]

Fair Value Measurements

8.   Fair Value Measurements

A majority of our financial assets and liabilities have been classified as Level 2. Our financial assets and liabilities (which include our cash equivalents, derivative contracts, marketable debt securities, and plan assets for deferred compensation) have been initially valued at the transaction price and subsequently valued, at the end of each reporting period, typically utilizing third party pricing services or other market observable data. The pricing services utilize industry standard valuation models, including both income and market based approaches and observable market inputs to determine value. These observable market inputs include reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events. We validate the prices provided by our third party pricing services by reviewing their pricing methods and matrices, obtaining market values from other pricing sources, analyzing pricing data in certain instances and confirming that the relevant markets are active. After completing our validation procedures, we did not adjust or override any fair value measurements provided by our pricing services as of June 30, 2011 and December 31, 2010.

Our strategic investments in publicly traded equity securities are classified as Level 1 assets as their fair values are readily determinable and based on quoted market prices.

We also maintain venture capital investments classified as Level 3 whose fair value is initially measured at transaction prices and subsequently valued using the pricing of recent financing or by reviewing the underlying economic fundamentals and liquidation value of the companies. These investments are the only investments for which we used Level 3 inputs to determine the fair value and represented approximately 0.2% and 0.3% of our total assets as of June 30, 2011 and December 31, 2010, respectively. These investments include investments in certain biotechnology oriented venture capital funds which primarily invest in small privately-owned, venture-backed biotechnology companies. The fair value of our investments in these venture capital funds has been estimated using the net asset value of the fund. The investments cannot be redeemed within the funds. Distributions from each fund will be received as the underlying investments of the fund are liquidated. The funds and therefore a majority of the underlying assets of the funds will not be liquidated in the near future. The underlying assets in these funds are initially measured at transaction prices and subsequently valued using the pricing of recent financings or by reviewing the underlying economic fundamentals and liquidation value of the companies that the funds invest in. We apply judgments and estimates when we validate the prices provided by third parties. While we believe the valuation methodologies are appropriate, the use of valuation methodologies is highly judgmental and changes in methodologies can have a material impact on our results of operations. Gains and losses (realized and unrealized) included in earnings for the period are reported in other income (expense), net.

In addition, in the fourth quarter of 2010, we recognized an in-process research and development asset and recorded a contingent consideration obligation related to our acquisition of Panima. Upon acquisition, we recorded a liability of $81.2 million representing the acquisition date fair value of the contingent consideration. Subsequent changes in the fair value of this obligation are recognized as adjustments to contingent consideration within our consolidated statement of income. We determined the fair value of the contingent consideration obligation based upon probability-weighted assumptions related to the achievement of certain milestone events and thus the likelihood of us making payments. We revalue the acquisition-related contingent consideration obligation on a recurring basis each reporting period. This fair value measurement is based on inputs not observable in the market and therefore represents a Level 3 measurement.

The fair value of our Level 3 contingent consideration obligation as of June 30, 2011 and December 31, 2010, was $84.6 million and $81.2 million, respectively. These valuations were determined based upon net cash outflow projections of $395.0 million, discounted using a rate of 5.7% and 6.1%, respectively, which is the cost of debt financing for market participants. The change in fair value of this obligation, of $2.2 million and $3.4 million for the three and six months ended June 30, 2011, respectively, was primarily due to changes in the discount rate and in the expected timing related to the achievement of certain developmental milestones and was recognized as a fair value adjustment of contingent consideration within our condensed consolidated statements of income for the three and six months ended June 30, 2011.

There were no transfers between fair value measurement levels during the six months ended June 30, 2011.

The tables below present information about our financial assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2011 and December 31, 2010, and indicate the fair value hierarchy of the valuation techniques we utilized to determine such fair value:

The fair values of the credit line from Dompé Farmaceutici SpA and our note payable to Fumedica were estimated using market observable inputs, including current interest and foreign currency exchange rates. The fair value of our Senior Notes was determined through market, observable, and corroborated sources.
