Cintas' senior notes, excluding the G&K senior notes assumed with the acquisition of G&K in fiscal 2017, are recorded at cost, net of debt issuance costs. The fair value of the long-term debt is estimated using Level 2 inputs based on general market prices. The carrying value and fair value of Cintas' debt as of August 31, 2018 were $2,550.0 million and $2,585.0 million, respectively, and as of May 31, 2018 were $2,550.0 million and $2,582.0 million, respectively.

The credit agreement that supports our commercial paper program was amended on September 16, 2016. The amendment increased the capacity of the revolving credit facility from $450.0 million to $600.0 million and added a $250.0 million term loan facility. The credit agreement has an accordion feature that provides Cintas the ability to request increases to the borrowing commitments under either the revolving credit facility or a new term loan of up to $250.0 million in the aggregate, subject to customary conditions. The maturity date of the credit agreement is September 15, 2021. As of August 31, 2018 and May 31, 2018, there was no commercial paper outstanding and no borrowings on our revolving credit facility.

Cintas uses interest rate locks to manage our overall interest expense as interest rate locks effectively change the interest rate of specific debt issuances. The interest rate locks are entered into to protect against unfavorable movements in the benchmark treasury rate related to forecasted debt issuances. Cintas used interest rate lock agreements to hedge against movements in the treasury rates at the time Cintas issued its senior notes in fiscal 2007, fiscal 2012, fiscal 2013 and fiscal 2017. The amortization of the cash flow hedges resulted in a decrease to other comprehensive income of $0.3 million and $0.2 million for the three months ended August 31, 2018 and 2017, respectively. During the quarter ended August 31, 2018, Cintas entered into interest rate lock agreements with a notional value of $500.0 million for a forecasted debt issuance. As of August 31, 2018, the fair value of these interest rate locks was a liability of $4.2 million recorded in current liabilities and in other comprehensive income, net of tax. The interest rate locks had no impact on net income or cash flows from continuing operations for the three months ended August 31, 2018.

Cintas has certain covenants related to debt agreements. These covenants limit Cintas’ ability to incur certain liens, to engage in sale-leaseback transactions and to merge, consolidate or sell all or substantially all of Cintas’ assets. These covenants also require Cintas to maintain certain debt to consolidated earnings before interest, taxes, depreciation and amortization (EBITDA) and interest coverage ratios. Cross-default provisions exist between certain debt instruments. If a default of a significant covenant were to occur, the default could result in an acceleration of the maturity of the indebtedness, impair liquidity and limit the ability to raise future capital. Cintas was in compliance with all debt covenants for all periods presented.
