We have a revolving credit facility (as amended as described below, the Amended Credit Facility) that terminates on August 2, 2021. During May 2019, we exercised our option to expand the revolving credit facility and increased the borrowing capacity from $500.0 million to $750.0 million. The Amended Credit Facility also includes a swingline loan sublimit of $25.0 million, which terminates on August 2, 2021. On December 20, 2019, we amended the revolving credit facility, which, among other things, primarily (i) modified the interest rates with respect to outstanding borrowings; (ii) allowed for the consummation of the Kosmos Acquisition; (iii) permitted the incurrence of additional indebtedness necessary to consummate the Kosmos Acquisition; (iv) modified the financial covenants to increase maximum leverage permitted under the Amended Credit Facility; and (v) made other changes, namely the selection of an alternate benchmark rate to replace the London Interbank Offered Rate (LIBOR). Borrowings under the Amended Credit Facility are guaranteed by substantially all of the Company's

subsidiaries. The debt under the Amended Credit Facility is not rated by ratings agencies. At our option, outstanding principal amounts on the Amended Credit Facility bear interest at a variable rate equal to either (i) the LIBOR plus an agreed margin (ranging from 125 to 200 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 alternate base rate, which is the highest of (a) the prime rate, (b) the federal funds rate plus ½% per annum, or (c) one month LIBOR plus 1.0%, in each case plus an agreed margin (ranging from 25 to 100 basis points). In the case of loans bearing interest at a rate based on the alternate base 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 six months at the option of the Company. The Company is also required to pay a commitment fee on unused available borrowings under the Amended Credit Facility ranging from 15 to 30 basis points depending upon the Leverage Ratio. The Amended 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 Amended 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 4.0:1.0 or less for fiscal quarters ended between December 31, 2019 and June 30, 2020; 3.75:1.0 for fiscal quarters ended between September 30, 2020 through December 31, 2020; and 3.5:1.0 for fiscal quarters after December 31, 2020. The Amended Credit Facility also requires us to maintain 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 December 31, 2019. We had $585.0 million of borrowings outstanding under the Amended Credit Facility at December 31, 2019. We had $158.1 million of available borrowings under the Amended Credit Facility, net of the outstanding letters of credit, at December 31, 2019, all of which is available for future borrowings based on our current leverage ratio.

The Amended 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 December 31, 2019, we had $6.9 million of outstanding letters of credit .

On December 20, 2019, we entered into a Credit Agreement (the Term Loan Agreement) establishing a $665.0 million term loan facility which, subject to the satisfaction of certain customary conditions, may be used to pay the Kosmos Purchase Price and fees and expenses incurred in connection with the Kosmos Acquisition. As of December 31, 2019, there has been no borrowing under the Term Loan Agreement. The commitments for the Term Loan Agreement terminate on the earlier of (a) the fifth business day following March 31, 2020, in the event that the term loans under the Term Loan Agreement have not been funded on or prior to such date and (b) the valid termination of the asset purchase agreement without the occurrence of the consummation of the Kosmos Acquisition. The term loan would mature on August 2, 2021.

Borrowings under the Term Loan Agreement will bear interest, at our option, at a floating rate per annum equal to either the alternate base rate (consistent with the Amended Credit Facility), plus a margin between 25 and 100 basis points, or based on the adjusted LIBOR plus a margin between 125 and 200 basis points, depending on the ratio of our consolidated indebtedness to consolidated EBITDA (consistent with the Amended Credit Facility). We must also maintain a ratio of consolidated indebtedness to consolidated EBITDA consistent with the Amended Credit Facility.

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 Amended Credit Facility and the Term Loan Agreement. 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 Amended Credit Facility. See Footnote (T) for more information on the guarantors of the Senior Public Notes.

On October 2, 2019, we paid $36.5 million to retire the remaining notes due under the Private Placement Senior 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.
