Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements Financial assets and liabilities are classified in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement: Level 1 (unadjusted quoted prices in active markets for identical assets or liabilities); Level 2 (observable market inputs, other than quoted prices included in Level 1); and Level 3 (unobservable inputs that cannot be corroborated by observable market data). We do not have any Level 3 assets or liabilities. Financial assets and liabilities measured at fair value are summarized below:

Cash equivalents Fair value of money market funds was determined based on quoted prices for identical assets in active markets. Commercial paper was measured at fair value using inputs based on quoted prices for similar securities in active markets. Short- and long-term securities Mutual funds were measured at fair value based on quoted prices for identical assets in active markets. Municipal bonds were measured at fair value based on market prices from recent trades of similar securities and are classified as short-term or long-term based on maturity date.
