The fair value of the interest rate swap contract 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 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.
