⁽¹⁾	The fair value of Level 1 securities is measured based on quoted prices in active markets for identical assets.

⁽²⁾

The fair value of Level 2 securities is valued using information obtained from pricing services, which obtain quoted market prices for similar instruments, non-binding market consensus prices that are corroborated by observable market data, or various other methodologies, to determine the appropriate value at the measurement date. We perform supplemental analysis to validate information obtained from these pricing services. As of March 5, 2015, no adjustments were made to such pricing information.


⁽³⁾	The maturities of our long-term marketable securities generally range from one to four years.

Proceeds from the sales of available-for-sale securities were $143 million and $376 million for the second quarter and first six months of 2015, respectively, and $110 million and $223 million for the second quarter and first six months of 2014, respectively. Gross realized gains and losses for the second quarter and first six months of 2015 and 2014 were not significant. As of March 5, 2015, none of our available-for-sale securities had been in a loss position for longer than 12 months.
