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 on a recurring basis were:

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
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. Mutual funds were measured at fair value based on quoted prices for identical assets in active markets.

Foreign currency instruments. We periodically enter into forward purchase foreign currency contracts, generally with an original maturity date of less than one year, to hedge foreign currency exchange rate risk. In the fourth quarter, we held foreign exchange forward contracts with a U.S. dollar notional value of $15.2 million, with the objective of reducing the exposure to fluctuations in the Canadian dollar and the Euro. The fair value of these contracts was a net liability of $0.1 million at year-end. These forward contracts are measured at fair value using unobservable market inputs, such as quotations on forward foreign exchange points and foreign currency exchange rates, and would be classified as Level 2 within the fair value hierarchy above.
