Long-Term Debt

We have a credit agreement (the “Credit Agreement”) with Bank of America, N.A., as administrative agent, and other lenders that provided for an unsecured total revolving commitment of $1.0 billion as of August 31, 2018. The commitment under the Credit Agreement terminates on December 7, 2021. Borrowings accrue interest under one of two alternative methods as described in the Credit Agreement. With each borrowing against our credit line, we can elect the interest rate method based on our funding needs at the time. We also incur loan commitment fees and letter of credit fees under the Credit Agreement. Outstanding letters of credit reduce the borrowing availability under the Credit Agreement on a dollar-for-dollar basis. As of August 31, 2018, the outstanding revolving loan principal balance was $282.0 million (excluding prepaid financing fees) and the face amount of outstanding letters of credit was $9.0 million. For the three- and six-months ended August 31, 2018, borrowings under the Credit Agreement incurred interest charges at rates ranging from 2.9% to 5.0% and 2.8% to 5.0%, respectively. For the three- and six-months ended August 31, 2017, borrowings under the Credit Agreement incurred interest charges at rates ranging from 2.5% to 4.8% and 2.3% to 4.8%, respectively. As of August 31, 2018, the amount available for borrowings under the Credit Agreement was $709.0 million. Covenants in our debt agreements limit the amount of total indebtedness we can incur. As of August 31, 2018, these covenants effectively limited our ability to incur more than $584.5 million of additional debt from all sources, including our Credit Agreement, or $709.0 million in the event a qualified acquisition is consummated. The following table summarizes our long-term debt as of the end of the periods shown:

(1)

The MBFC Loan is unsecured with an original balance of $37.6 million and interest set and payable quarterly at a Base Rate, plus a margin of up to 1.0%, or applicable LIBOR plus a margin of up to 2.0%, as determined by the interest rate elected and the Leverage Ratio. The loan is subject to holder’s call on or after March 1, 2018. The loan can be prepaid without penalty. The remaining principal balance is payable as follows: $1.9 million annually on March 1, 2019 through 2022; and $14.8 million on March 1, 2023. Any remaining outstanding principal and interest is due upon maturity on March 1, 2023.


(2)	Floating interest rates are hedged with an interest rate swap to effectively fix interest rates on $100 million of the outstanding principal balance under the Credit Agreement. Notes 12 and 13 to these condensed consolidated financial statements provide additional information regarding the interest rate swap.

At August 31, 2018 and February 28, 2018, our long-term debt has floating interest rates, and its book value approximates its fair value.

All of our debt is unconditionally guaranteed, on a joint and several basis, by the Company and certain of its subsidiaries. Our debt agreements require the maintenance of certain financial covenants, including maximum leverage ratios, minimum interest coverage ratios and minimum consolidated net worth levels (as each of these terms is defined in the various agreements). Our debt agreements also contain other customary covenants. We were in compliance with the terms of these agreements as of August 31, 2018.
