At December 31, 2011 and December 31, 2010 the following financial assets and liabilities are measured at fair value on a recurring basis using quoted prices in active markets for identical assets (Level 1); significant other observable inputs (Level 2); and significant unobservable inputs (Level 3).

Certain estimates and judgments were required to develop the fair value amounts. The fair value amounts shown above are not necessarily indicative of the amounts that the Company would realize upon disposition, nor do they indicate the Company's intent or ability to dispose of the financial instrument.

The following methods and assumptions were used to estimate the fair value of each material class of financial instrument:

Assets Measured at Fair Value on a Recurring Basis Using Significant Unobservable Inputs (Level 3)

The change in the fair value of the Company's contingent consideration receivable, which is measured at fair value on a recurring basis using significant unobservable inputs (Level 3), is as follows:

	Contingent consideration receivable
	2011
	$'M
	____________

Balance at January 1,	61.0
Loss recognized in the income statement due to change in fair value during the period	(6.0)
Reclassification of amounts due from Noven to Other receivables within Other current assets	(16.5)
Foreign exchange translation recorded to other comprehensive income	(0.7)

Balance at December 31,	37.8

Assets Measured at Fair Value on a Non-Recurring Basis using Significant Unobservable Inputs (Level 3)

In the year to December 31, 2011 the Company reviewed certain of its indefinite lived IPR&D intangible assets (“IPR&D assets”) for impairment and recognized an impairment charge of $16.0 million, recorded within R&D in the consolidated income statement, to write-down these IPR&D assets to their fair value. The fair value of these IPR&D assets was determined using the income approach, which used significant unobservable (Level 3) inputs. These unobservable inputs included, inter alia, risk-adjusted forecast future cash flows to be generated by these IPR&D assets, contributory asset charges for other assets employed in these IPR&D projects and the determination of an appropriate discount rate to be applied in calculating the present value of forecast future cash flows. The fair value of these IPR&D assets, determined at the time of the impairment review, was $108.0 million.

Financial assets and liabilities that are not measured at fair value on a recurring basis

The carrying amounts and estimated fair values as at December 31, 2011 and December 31, 2010 of the Company's financial assets and liabilities which are not measured at fair value on a recurring basis are as follows:

	December 31, 2011		December 31, 2010
	Carrying		Carrying
	amount	Fair value	amount	Fair value
	$’M	$’M	$’M	$’M
	____________	____________	____________	___________

Financial liabilities:
Convertible bonds	1,100.0	1,309.7	1,100.0	1,139.8
Building financing obligation	8.2	9.7	8.4	8.2
	____________	____________	____________	___________

The following methods and assumptions were used to estimate the fair value of each material class of financial instrument:

The carrying amounts of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses materially approximate to fair value because of the short-term maturity of these amounts.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
