We have a revolving credit facility (the Credit Facility) that terminates on August 2, 2021. During May 2019, we exercised our option to expand the Credit Facility and increased the borrowing capacity from $500.0 million to $750.0 million. The Credit Facility also includes a swingline loan sublimit of $25.0 million, which terminates on August 2, 2021. Borrowings under the Credit Facility are guaranteed by substantially all of the Company’s subsidiaries. The debt under the Credit Facility is not rated by ratings agencies.

At our option, outstanding principal amounts on the Credit Facility bear interest at a variable rate equal to either (i) the London Interbank Offered Rate (LIBOR) plus an agreed margin (ranging from 100 to 225 basis points), which is to be established quarterly based on the Company’s ratio of consolidated EBITDA, defined as earnings before interest, taxes, depreciation, and amortization, to the Company’s consolidated indebtedness (the Leverage Ratio); or (ii) an alternative base rate which is the higher of (a) the prime rate or (b) the federal funds rate

plus ¹⁄₂% per annum plus an applicable rate (ranging from 0 to 125 basis points). In the case of loans bearing interest at a rate based on the federal funds rate, interest payments are payable quarterly. In the case of loans bearing interest at a rate based on LIBOR, interest is payable at the end of the LIBOR advance periods, which can be up to nine months at the option of the Company. The Company is also required to pay a commitment fee on unused available borrowings under the Credit Facility ranging from 10 to 35 basis points depending upon the Leverage Ratio. The Credit Facility contains customary covenants that restrict our ability to incur additional debt; encumber our assets; sell assets; make or enter into certain investments, loans, or guaranties; and enter into sale and leaseback arrangements. The Credit Facility also requires us to maintain a consolidated indebtedness ratio (calculated as consolidated indebtedness to consolidated earnings before interest, taxes, depreciation, amortization, certain transaction-related deductions, and other non-cash deductions) of 3.5:1.0 or less and an interest coverage ratio (consolidated earnings before interest, taxes, depreciation, amortization, certain transaction-related deductions, and other non-cash deductions to consolidated interest expense) of at least 2.5:1.0. We were in compliance with all financial ratios and tests at September 30, 2019. We had $585.0 million of borrowings outstanding at September 30, 2019. Based on our Leverage Ratio, we had $158.1 million of available borrowings, net of the outstanding letters of credit, at September 30, 2019.

The Credit Facility has a $40.0 million letter of credit facility. Under the letter of credit facility, the Company pays a fee at a per annum rate equal to the applicable margin for Eurodollar loans in effect from time to time plus a one-time letter of credit fee in an amount equal to 0.125% of the initial stated amount. At September 30, 2019, we had $6.9 million of outstanding letters of credit.

On August 2, 2016, the Company issued $350.0 million aggregate principal amount of 4.500% senior notes (Senior Unsecured Notes) due August 2026. Interest on the Senior Unsecured Notes is payable semiannually on February 1 and August 1 of each year until all of the outstanding notes are paid. The Senior Unsecured Notes rank equal to existing and future senior indebtedness, including the Credit Facility and the Private Placement Senior Unsecured Notes. Prior to August 1, 2021, we may redeem some or all of the Senior Unsecured Notes at a price equal to 100% of the principal amount, plus a “make-whole” premium. Beginning August 1, 2021, we may redeem some or all of the Senior Unsecured Notes at the redemption prices set forth below (expressed as a percentage of the principal amount being redeemed):

	Percentage
2021		102.25	%
2022		101.50	%
2023		100.75	%
2024 and thereafter		100.00	%

The Senior Unsecured Notes contain covenants that limit our ability and/or our guarantor subsidiaries' ability to create or permit to exist certain liens; enter into sale and leaseback transactions; and consolidate, merge, or transfer all or substantially all of our assets. The Company’s Senior Unsecured Notes are fully, unconditionally, jointly, and severally guaranteed by each of our subsidiaries that are guarantors under the Credit Facility and Private Placement Senior Unsecured Notes. See Footnote (S) for more information on the guarantors of the Senior Public Notes.

On October 2, 2007, in a private placement transaction, we entered into a Note Purchase Agreement (the 2007 Note Purchase Agreement) in connection with our sale of $200.0 million of senior unsecured notes, designated as Series 2007A Senior Notes (the Series 2007A Senior Unsecured Notes). The Series 2007A Senior Unsecured Notes, which are guaranteed by substantially all of our subsidiaries, were sold at par and issued in four tranches.

At September 30, 2019, the amount outstanding for the remaining tranche is as follows:

		Principal		Maturity Date		Interest Rate
Tranche D		$36.5 million		October 2, 2019			6.48	%

Interest for the Series 2007A Senior Unsecured Notes is payable semi-annually April 2 and October 2 of each year until all principal is paid for the respective tranche. On October 2, 2019, we repaid all outstanding notes related to the Private Placement Unsecured Notes.

We lease one of our cement plants from the city of Sugar Creek, Missouri. The city of Sugar Creek issued industrial revenue bonds to partly finance improvements to the cement plant. The lease payments due to the city of Sugar Creek under the cement plant lease, which was entered into upon the sale of the industrial revenue bonds, are equal in amount to the payments required to be made by the city of Sugar Creek to the holders of the industrial revenue bonds. Because we hold all outstanding industrial revenue bonds, no debt is reflected on our financial statements in connection with our lease of the cement plant. Upon expiration of the lease in fiscal 2021, we have the option to purchase the cement plant for a nominal amount.
