(1) Carrying amount is net of unamortized debt discount and deferred debt issuance costs. Total unamortized debt discounts were

$14.4 million and $15.1 million as of March 31, 2022 and December 31, 2021, respectively. Total deferred debt issuance costs were $12.1 million and $12.5 million as of March 31, 2022 and December 31, 2021, respectively.

As of March 31, 2022, the Company maintained a $1.0 billion five-year unsecured revolving credit facility (the "Credit Agreement") with a syndicate of banks which expires on October 4, 2024. The Company uses the Credit Agreement principally as liquidity back-up for its commercial paper program and for general corporate purposes. At the Company's election, loans under the Credit Agreement will bear interest at a base rate plus an applicable margin. The Credit Agreement requires the Company to pay a facility fee and imposes various restrictions on the Company such as, among other things, a requirement to maintain a minimum interest coverage ratio of consolidated EBITDA to consolidated net interest expense of not less than 3.0 to 1. As of March 31, 2022 and December 31, 2021, there were no borrowings under the Credit Agreement.

The Company was in compliance with all covenants in the Credit Agreement and other long-term debt covenants at March 31, 2022 and had an interest coverage ratio of consolidated EBITDA to consolidated net interest expense of 17.7 to 1.

Letters of Credit and other Guarantees

As of March 31, 2022, the Company had approximately $149.7 million outstanding in letters of credit, surety bonds, and performance and other guarantees which expire on various dates through 2029. These letters of credit and bonds are primarily issued as security for insurance, warranty and other performance obligations. In general, we would only be liable for the amount of these guarantees in the event of default in the performance of our obligations.
