Fair Value, Assets, Liabilities and Stockholders' Equity Measured on Recurring Basis [Abstract]

The company uses a three-level classification hierarchy of fair value measurements for disclosure purposes.


•	Level 1 inputs, which are considered the most reliable evidence of fair value, consist of quoted prices (unadjusted) for identical assets or liabilities in active markets.


•	Level 2 inputs consist of observable market data, such as quoted prices for similar assets and liabilities in active markets, or inputs other than quoted prices that are directly observable.


•	Level 3 inputs consist of unobservable inputs which are derived and cannot be corroborated by market data or other entity-specific inputs.

Level 1 assets generally include U.S. Treasury securities and investments in publicly traded mutual funds with quoted market prices. In general, the company uses quoted prices in active markets for identical assets to determine the fair value of marketable securities and equity investments. If quoted prices are not available to determine fair value, the company uses other inputs that are directly observable.

Assets included in level 2 generally consist of asset-backed securities. Asset-backed securities were measured at fair value based on matrix pricing using prices of similar securities with similar inputs such as maturity dates, interest rates and credit ratings.

The company determined the fair value of its contingent consideration liability, considered a level 3 liability, using a discounted cash flow model to calculate the present value of future payouts. The liability was included in level 3 because management used significant unobservable inputs, including a discount rate of 20% and a payout probability of 100%. Significant changes in these inputs, in isolation, would result in a significantly different fair value.

Financial assets and liabilities recorded in the consolidated balance sheet as of September 30, 2015 were classified in their entirety based on the lowest level of input that was significant to each asset or liability's fair value measurement. The following tables present financial instruments measured at fair value on a recurring basis:



	September 30, 2015
(in millions)	Level 1		Level 2		Level 3		Total
Assets at Fair Value:
Marketable securities:
U.S. Treasury securities	$	19.2	$	—	$	—	$	19.2

Equity securities	0.1		—		—		0.1

Liabilities at Fair Value:
Contingent consideration	$	—	$	—	$	0.4	$	0.4
Total Liabilities at Fair Value	$	—	$	—	$	0.4	$	0.4

(1) Performance bonds and guaranty fund contributions on the consolidated balance sheet at September 30, 2015 include U.S. Treasury securities purchased with cash collateral.

There were no transfers of assets or liabilities between level 1, level 2 and level 3 during the first nine months of 2015. There were no level 3 assets valued at fair value on a recurring basis during the first nine months of 2015. The following is a reconciliation of level 3 liabilities valued at fair value on a recurring basis during the first nine months of 2015.



(in millions)	Contingent Consideration
Fair value of liability at December 31, 2014	$	17.7
Realized and unrealized (gains) losses:
Included in other expenses	1.4
Settlements	(18.7		)
Fair value of liability at September 30, 2015	$	0.4

There were no level 3 assets or level 3 liabilities valued at fair value on a nonrecurring basis during the first nine months of 2015.

The following presents the estimated fair values of long-term debt notes, which are carried at amortized cost on the consolidated balance sheets. The fair values, which are classified as level 2 under the fair value hierarchy, were estimated using quoted market prices. At September 30, 2015, the fair values were as follows:



(in millions)	Fair Value
$750.0 million fixed rate notes due September 2022, stated rate of 3.00%	$	753.9
$750.0 million fixed rate notes due March 2025, stated rate of 3.00%	733.8
$750.0 million fixed rates notes due September 2043, stated rate of 5.30%	851.7
