 Fair Value Measurements

Authoritative guidance for fair value measurements establishes a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1	Unadjusted quoted prices in active markets for identical assets or liabilities. An active market for the asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Financial Instruments that are Measured at Fair Value on a Recurring Basis

We primarily apply the market approach to determine the fair value of financial instruments that are measured at fair value on a recurring basis. There were no changes to our valuation techniques used to determine the fair value of financial instruments during 2012 as compared to the prior year.

The following tables present information about our financial instruments measured at fair value on a recurring basis as of December 31, 2012 and December 31, 2011, and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value.

	December 31, 2012												Balance Sheet Classification

Assets
Cash equivalents	$	1,806.6		$	0.0		$	0.0		$	1,806.6		Cash and cash equivalents

¹  Relates to unconditional obligations to purchase additional noncontrolling equity shares of consolidated subsidiaries. Fair value measurement of the obligation was based upon the amount payable as if the forward contracts were settled. The amount redeemable within the next twelve months is classified in accrued liabilities; any interests redeemable thereafter are classified in other non-current liabilities.

The following tables present additional information about financial instruments measured at fair value on a recurring basis and for which we utilize Level 3 inputs to determine fair value.

	Years ended December 31,
Liabilities	2012			2011
Mandatorily redeemable noncontrolling interests -     Balance at beginning of period	$	58.9		$	52.0
Level 3 additions	0.0			28.1
Level 3 reductions	(34.9		)	(28.0		)
Realized losses included in net income	(1.4		)	(6.7		)
Foreign currency translation	(0.1		)	0.1
Mandatorily redeemable noncontrolling interests -     Balance at end of period	$	25.3		$	58.9

Level 3 reductions primarily consist of cash payments made related to unconditional obligations to purchase additional equity interests in previous acquisitions, which are classified within the financing section of our Consolidated Statements of Cash Flows. Level 3 additions relate to new unconditional obligations to purchase additional equity interests in previous acquisitions for cash in future periods. Realized losses included in net income for mandatorily redeemable noncontrolling interests are reported as a component of interest expense in our Consolidated Statements of Operations.

Gross unrealized and realized gains and losses for our long-term investments and short-term marketable securities were not material for the years ended December 31, 2012, 2011 and 2010.

Financial Instruments that are not Measured at Fair Value on a Recurring Basis

The following table presents information about our financial instruments that are not measured at fair value on a recurring basis as of December 31, 2012, and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value.

	December 31, 2012
	Level 1		Level 2		Level 3		Total
Total long-term debt	$	0.0	$	2,292.4	$	90.8	$	2,383.2

Our long-term debt comprises senior notes and other notes payable.  The fair value of our senior notes traded over-the-counter is based on quoted prices for such securities, but which fair value can also be derived from inputs that are readily observable. Therefore, these senior notes are classified as Level 2 within the fair value hierarchy.  Our other notes payable are not actively traded and their fair value is not solely derived from readily observable inputs. Thus, the fair value of our other notes payable is determined based on a discounted cash flow model and other proprietary valuation methods, and therefore is classified as Level 3 within the fair value hierarchy.  See Note 2 for further information on our long-term debt. 

Non-financial Instruments that are Measured at Fair Value on a Nonrecurring Basis

Certain non-financial instruments are measured at fair value on a nonrecurring basis, primarily goodwill, intangible assets, and property, plant and equipment. Accordingly, these assets are not measured and adjusted to fair value on an ongoing basis but are subject to periodic evaluations for potential impairment.
