Fair-Value Measurements [Abstract]

Fair-Value Measurements

4. Fair-Value Measurements

Assets and liabilities reported at fair value are classified in one of the following three levels within the fair-value hierarchy:

Level 1: Quoted market prices in active markets for identical assets or liabilities

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data

Level 3: Unobservable inputs that are not corroborated by market data

Financial Assets Measured at Fair Value on a Recurring Basis

The following table summarizes the valuation of financial instruments within the fair-value hierarchy:

	March 31, 2012
(Dollars in thousands)	Total		Level 1		Level 2		Level 3
Cash equivalents	$	351,020	$	84,870	$	266,150	$	--
Current marketable securities		16,215		--		16,215		--
Other marketable securities		5,394		--		--		5,394

	December 31, 2011
(Dollars in thousands)	Total		Level 1		Level 2		Level 3
Cash equivalents	$	398,450	$	84,872	$	313,578	$	--
Current marketable securities		13,255		--		13,255		--
Other marketable securities		5,354		--		--		5,354

Cash equivalents consist of short-term interest-bearing instruments (primarily commercial paper, certificates of deposit and money-market funds) with maturities of three months or less at the date of purchase. Current marketable securities consist of variable-rate demand notes.

Money-market funds reflect their published net asset value and are classified as Level 1 instruments. Commercial paper, certificates of deposit and variable-rate demand notes are generally valued using published interest rates for instruments with similar terms and maturities, and accordingly, are classified as Level 2 instruments. At March 31, 2012, the weighted-average remaining maturity of the cash equivalents was less than one month. Based on their short maturities, the carrying amount of the cash equivalents approximates their fair value.

Con-way holds one auction-rate security, which is valued with an income approach that utilizes a discounted cash flow model. The following table summarizes the change in fair values of Con-way's auction-rate security, which was valued using Level 3 inputs:

(Dollars in thousands)	Auction-rate security
