During 2020, the Company placed cash on deposit with a financial institution to be held as cash collateral for the Company's outstanding letters of credit. In prior years, the Company used a portion of its credit agreement as collateral for letters of credit, which decreased availability under its revolving credit facility. See Note 13, "Long-term Debt," for further information on the Company's credit agreement.
