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

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. At December 31, 2012, current marketable securities consisted 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 December 31, 2013, 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.
Level 3 investments consisted of one auction-rate security at December 31, 2011, which was valued with an income approach that utilized a discounted cash flow model. This investment was sold in the third quarter of 2012. The following table summarizes the change in fair value of Con-way's auction-rate security, which was valued using Level 3 inputs:
