We determine the fair value of our available-for-sale securities based on quoted market prices (Level 1). We generally use derivatives for hedging purposes pursuant to ASC 815-10, which are valued based on Level 2 inputs in the ASC 820 fair value hierarchy. The fair value of our derivative financial instruments is determined by a mark-to-market valuation based on forward curves using observable market prices.

The carrying value of our long-term debt approximates fair value.
