| | (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 measured 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 3, 2016, no adjustments were made to such pricing information. |
| | (3) | The maturities of long-term marketable investments range from one to four years. |
