Prism insures a portion of our general liability, workers’ compensation and automobile liability risks using reinsurance agreements to meet statutory requirements. The reinsurance carrier requires Prism to maintain fixed-maturity investments for the purpose of providing collateral for Prism’s obligations under the reinsurance agreements. The amortized cost and estimated fair values of these bonds at August 31, 2019, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities, as borrowers may have the right to call or prepay obligations with or without penalty.

Derivative instruments In August 2019, we entered into an interest rate swap to hedge exposure to variability in cash flows from interest payments on our floating-rate revolving credit facility. As of August 31, 2019, the interest rate swap contract had a notional value of $85 million. We periodically enter into forward purchase foreign currency cash flow hedge contracts, generally with an original maturity date of less than one year, to hedge foreign currency exchange rate risk. As of August 31, 2019, we held foreign exchange forward contracts with a U.S. dollar notional value of $27.8 million, with the objective of reducing the exposure to fluctuations in the Canadian dollar and the Euro. These derivative instruments are recorded within our consolidated balance sheets within other current assets and liabilities. Gains or losses associated with these instruments are recorded as a component of accumulated other comprehensive income. 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 financial assets or liabilities.

Money market funds and commercial paper 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. These assets are included within cash and cash equivalents on our consolidated balance sheets. Municipal and corporate bonds Municipal and corporate bonds were measured at fair value based on market prices from recent trades of similar securities and are classified within our consolidated balance sheets as other current or other non-current assets based on maturity date. Derivative instruments The interest rate swap is measured at fair value using unobservable market inputs, based off of benchmark interest rates. Forward foreign exchange contracts are measured at fair value using unobservable market inputs, such as quotations on forward foreign exchange points and foreign currency exchange rates. Derivative positions are primarily valued using standard calculations and models that use as their basis readily observable market parameters. Industry standard data providers are our primary source for forward and spot rate information for both interest and currency rates.
