The fair value of interest rate swap contracts is based on a model-driven valuation using the observable components (e.g., interest rates), which are observable at commonly quoted intervals for the full term of the contracts. The fair value of the Company’s commodity swap contracts is based on an analysis of the expected cash flow of the contract in combination with observable forward price inputs obtained from a third-party pricing source. The calculations are adjusted for credit risk. Therefore, the Company’s derivative assets and liabilities are classified within Level 2 of the fair value hierarchy. Derivative assets are included within “Prepaid expenses and other current assets” and “Other assets” on the Company’s Consolidated Balance Sheets. Derivative liabilities are included within “Accrued expense and other current liabilities” and “Other long-term liabilities” on the Company’s Consolidated Balance Sheets.
