Debt

In December 2016, we amended and restated the credit agreement governing our credit facility to, among other changes, increase the amount of the revolving credit facility to $175.0 million, extend the maturity date to November 2021 and to modify the financial covenants under the credit agreement. We had $45.0 million outstanding on our revolving credit facility as of March 4, 2017 and no borrowings outstanding as of February 27, 2016. As defined within our facility, we have two financial covenants that require us to stay below a maximum debt-to-EBITDA ratio and maintain a minimum ratio of interest expense-to-EBITDA. Both ratios are computed quarterly, with EBITDA calculated on a rolling four-quarter basis. If the Company is not in compliance with either of these covenants, our credit facility may be terminated and/or any amounts then outstanding may be declared immediately due and payable. At March 4, 2017, we were in compliance with both financial covenants. We have the ability to issue letters of credit of up to $70.0 million under this credit facility, the outstanding amounts of which decrease the available commitment. At March 4, 2017, $106.5 million was available under this credit facility.

Debt at March 4, 2017 also included $20.4 million of industrial revenue bonds that mature in fiscal years 2021 through 2043. The fair value of the industrial revenue bonds approximated carrying value at March 4, 2017, due to the variable interest rates on these instruments. The bonds would be classified as Level 2 within the fair value hierarchy described in Note 5.

We also maintain a $4.0 million Canadian dollar revolving demand facility. No borrowings were outstanding under the facility as of March 4, 2017 or February 27, 2016. Borrowings under the facility are made available at the sole discretion of the lender and are payable on demand, with interest at rates specified in the credit agreement for the demand facility.
