Debt

During fiscal 2014, the Company entered into an amendment to its existing $100.0 million revolving credit facility. The expiration date was extended by one year to November 2018 and the letter of credit facility was reduced to $50.0 million from $60.0 million, the outstanding amounts of which decrease the available commitment. No other provisions of the original agreement were materially amended by the amended credit agreement. No borrowings were outstanding under the facility as of March 1, 2014 or March 2, 2013. Letters of credit issued under the facility decrease the amount of available commitment; $76.5 million was available under the facility at March 1, 2014 and $76.6 million was available at March 2, 2013.

The credit facility requires the Company to maintain a minimum level of net worth as defined in the credit facility based on certain quarterly financial calculations. The minimum required net worth computed in accordance with the credit agreement at March 1, 2014 was $287.5 million, whereas the Company’s net worth as defined in the credit facility was $352.6 million. The credit facility also requires that the Company maintain an adjusted debt-to-EBITDA ratio of not more than 3.00. This ratio is computed quarterly, with EBITDA computed on a rolling four-quarter basis. For purposes of calculating the adjusted debt in the adjusted debt-to-EBITDA ratio, the Company reduces non-credit facility debt for up to $25 million to the extent of unrestricted cash balances, cash equivalents and short-term marketable securities available for sale in excess of $15 million. The Company’s ratio was 0.25 at March 1, 2014. If the Company is not in compliance with either of these covenants, the lenders may terminate the commitment and/or declare any loan then outstanding to be immediately due and payable. At March 1, 2014, the Company was in compliance with the financial covenants of the credit facility.

During the first quarter of fiscal 2014, $10.0 million of recovery zone facility bonds that had previously been issued for future investment in the Company's Architectural Glass fabrication facility in Utah were redeemed at par. In connection with redeeming this debt in the first quarter of fiscal 2014, the Company expensed $0.2 million of debt issue costs that had previously been deferred and were being amortized over the term of the debt.
