We maintain credit facilities with third-party lenders, which we use for a variety of purposes. On October 31, 2017, CBRE Services, Inc. (CBRE Services), our wholly-owned subsidiary, entered into a Credit Agreement (the 2017 Credit Agreement), which refinanced and replaced our prior credit agreement (the 2015 Credit Agreement). We used $200.0 million of borrowings from the tranche A term loan facility and $83.0 million of revolving credit facility borrowings under the 2017 Credit Agreement, in addition to cash on hand, to repay all amounts outstanding under the 2015 Credit Agreement.

The 2017 Credit Agreement is a senior unsecured credit facility that is jointly and severally guaranteed by us and certain of our subsidiaries. As of September 30, 2018, the 2017 Credit Agreement provided for the following: (1) a $2.8 billion revolving credit facility, which includes the capacity to obtain letters of credit and swingline loans and matures on October 31, 2022 and (2) a $750.0 million delayed draw tranche A term loan facility, requiring quarterly principal payments, which began on March 5, 2018 and continue through maturity on October 31, 2022, provided that in the event that our leverage ratio (as defined in the 2017 Credit Agreement) is less than or equal to 2.50 to 1.00 on the last day of the fiscal quarter immediately preceding any such payment date, no such quarterly principal payment shall be required on such date.

On March 14, 2013, CBRE Services issued $800.0 million in aggregate principal amount of 5.00% senior notes due March 15, 2023. The 5.00% senior notes were unsecured obligations of CBRE Services, senior to all of its current and future subordinated indebtedness, but effectively subordinated to all of its current and future secured indebtedness. The 5.00% senior notes were jointly and severally guaranteed on a senior basis by us and each domestic subsidiary of CBRE Services that guaranteed our 2017 Credit Agreement. Interest accrued at a rate of 5.00% per year and was payable semi-annually in arrears on March 15 and September 15. The 5.00% senior notes were redeemable at our option, in whole or in part, on March 15, 2018 at a redemption price of 102.5% of the principal amount on that date. We redeemed these notes in full on March 15, 2018 and incurred charges of $28.0 million, including a premium of $20.0 million and the write-off of $8.0 million of unamortized deferred financing costs. We funded this redemption with $550.0 million of borrowings from our tranche A term loan facility and borrowings from our revolving credit facility under our 2017 Credit Agreement. The amount of the 5.00% senior notes, net of unamortized debt issuance costs, included in the accompanying consolidated balance sheets was $791.7 million at December 31, 2017.

The indentures governing our 4.875% senior notes and 5.25% senior notes contain restrictive covenants that, among other things, limit our ability to create or permit liens on assets securing indebtedness, enter into sale/leaseback transactions and enter into consolidations or mergers. In addition, our 2017 Credit Agreement also requires us to maintain a minimum coverage ratio of consolidated EBITDA (as defined in the 2017 Credit Agreement) to consolidated interest expense of 2.00x and a maximum leverage ratio of total debt less available cash to consolidated EBITDA (as defined in the 2017 Credit Agreement) of 4.25x (and in the case of the first four full fiscal quarters following consummation of a qualified acquisition (as defined in the 2017 Credit Agreement), 4.75x) as of the end of each fiscal quarter. On this basis, our coverage ratio of consolidated EBITDA to consolidated interest expense was 18.62x for the trailing twelve months ended September 30, 2018, and our leverage ratio of total debt less available cash to consolidated EBITDA was 0.79x as of September 30, 2018.

Short-Term Borrowings

Revolving Credit Facility

As of September 30, 2018, $141.0 million was outstanding under the revolving credit facility. In addition, as of September 30, 2018, letters of credit totaling $2.0 million were outstanding under our revolving credit facility under our 2017 Credit Agreement. These letters of credit, which reduce the amount we may borrow under the revolving credit facility, were primarily issued in the ordinary course of business. As of December 31, 2017, no amounts were outstanding under the revolving credit facility other than letters of credit totaling $2.0 million.

Warehouse Lines of Credit

CBRE Capital Markets has warehouse lines of credit with third-party lenders for the purpose of funding mortgage loans that will be resold, and a funding arrangement with Fannie Mae for the purpose of selling a percentage of certain closed multifamily loans to Fannie Mae. These warehouse lines are recourse only to CBRE Capital Markets and are secured by our related warehouse receivables. See Note 5 for additional information.
