Foreign Currency Forward Contracts
The Company’s foreign currency forward contracts are valued using models that maximize the use of market observable inputs including interest rate curves and both forward and spot prices for currencies and are categorized as Level 2 within the fair value hierarchy.
Interest Rate Swaps
The fair value of interest rate swap contracts is calculated based on the fixed rate, notional principal, settlement date and present value of the future cash inflows and outflows based on the terms of the agreement and the future floating interest rates as determined by a future interest rate yield curve. The model used to value the interest rate swap contracts is based upon well recognized financial principles, and interest rate yield curves can be validated through readily observable data by external sources. Although readily observable data is used in the valuations, different valuation methodologies could impact the estimated fair value. Accordingly, the interest rate swap contracts are categorized as Level 2 within the fair value hierarchy. Gain and loss on interest rate swap contracts are immaterial and included in Other income (expense).
