We maintain credit facilities with third-party lenders, which we use for a variety of purposes. On October 31, 2017, CBRE Services 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. On December 20, 2018, CBRE Global Acquisition Company, a wholly-owned subsidiary of CBRE Services, entered into an incremental term loan assumption agreement with a syndicate of banks jointly led by Wells Fargo Bank and National Westminster Bank plc to establish a euro term loan facility under the 2017 Credit Agreement in an aggregate principal amount of 400.0 million euros. The proceeds from the euro term loan facility were used to repay a portion of the U.S. dollar denominated term loans outstanding under the 2017 Credit Agreement. On March 4, 2019, CBRE Services entered into an additional incremental assumption agreement with respect to the 2017 Credit Agreement (the 2017 Agreement as amended by such incremental assumption agreement, the 2019 Credit Agreement), which (i) extended the maturity of the U.S. dollar tranche A term loans under the 2017 Credit Agreement, (ii) extended the termination date of the revolving credit commitments available under the 2017 Credit Agreement and (iii) made certain changes to the interest rates and fees applicable to such tranche A term loans and revolving credit commitments. The proceeds from the new tranche A term loan facility under the 2019 Credit Agreement were used to repay the $300.0 million of tranche A term loans outstanding under the 2017 Credit Agreement.

The 2019 Credit Agreement is a senior unsecured credit facility that is jointly and severally guaranteed by us and certain of our subsidiaries. As of December 31, 2019, the 2019 Credit Agreement provided for the following: (1) a $2.8 billion incremental revolving credit facility, which includes the capacity to obtain letters of credit and swingline loans and terminates on March 4, 2024; (2) a $300.0 million incremental tranche A term loan facility maturing on March 4, 2024, requiring quarterly principal payments unless our leverage ratio (as defined in the 2019 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 and (3) a €400.0 million term loan facility due and payable in full at maturity on December 20, 2023.

As of December 31, 2019, borrowings under the tranche A term loan facility under the 2019 Credit Agreement bear interest, based at our option, on either (1) the applicable fixed rate plus 0.875% to 1.25% or (2) the daily rate plus 0.0% to 0.25%, in each case as determined by reference to our Credit Rating (as defined in the 2019 Credit Agreement) and borrowings under the euro term loan facility under the 2019 Credit Agreement bear interest at a minimum rate of 0.75% plus EURIBOR. We had $297.3 million of tranche A term loan borrowings outstanding under the 2019 Credit Agreement (at an interest rate of 2.69%), net of unamortized debt issuance costs, included in the accompanying consolidated balance sheets at December 31, 2019. In addition, as of December 31, 2019, we had $447.3 million of euro term loan borrowings outstanding under the 2019 Credit Agreement (at an interest rate of 0.75%), net of unamortized debt issuance costs, which was included in the accompanying consolidated balance sheets.

The 2017 Credit Agreement was a senior unsecured credit facility that was jointly and severally guaranteed by us and certain of our subsidiaries. Our 2017 Credit Agreement provided for the following: (1) a $2.8 billion revolving credit facility, which included the capacity to obtain letters of credit and swingline loans and had a termination date of October 31, 2022; (2) a $750.0 million delayed draw tranche A term loan facility which would have matured on October 31, 2022 and which required quarterly principal payments unless our leverage ratio (as defined in the 2017 Credit Agreement) was less than or equal to 2.50 to 1.00 on the last day of the fiscal quarter immediately preceding any such payment date and (3) a €400.0 million term loan facility which would have been due and payable in full at maturity on December 20, 2023. We had $294.4 million of tranche A term loan borrowings outstanding under the 2017 Credit Agreement (at an interest rate of 3.36%), net of unamortized debt issuance costs, included in the accompanying consolidated balance sheets at December 31, 2018. In addition, as of December 31, 2018, we had $456.9 million of euro term loan borrowings outstanding under the 2017 Credit Agreement (at an interest rate of 0.75%), net of unamortized debt issuance costs, which was included in the accompanying consolidated balance sheets.

In March 2011, we entered into five interest rate swap agreements, all with effective dates in October 2011, and immediately designated them as cash flow hedges in accordance with FASB ASC Topic 815, “Derivatives and Hedging”. The purpose of these interest rate swap agreements was to attempt to hedge potential changes to our cash flows due to the variable interest nature of our senior term loan facilities. The total notional amount of these interest rate swap agreements was $400.0 million, $200.0 million of which expired in October 2017 and $200.0 million of which expired in September 2019. The ineffective portion of the change in fair value of the derivatives was recognized directly in earnings. There was no significant hedge ineffectiveness for the years ended December 31, 2019, 2018 and 2017. The effective portion of changes in the fair value of derivatives designated and qualifying as cash flow hedges was recorded in accumulated other comprehensive loss on the balance sheet and was subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. We reclassified $1.2 million, $2.7 million and $7.4 million for the years ended December 31, 2019, 2018, and 2017, respectively, from accumulated other comprehensive loss to interest expense. In addition, we recorded a net loss of $0.1 million and net gains of $1.0 million and $0.9 million for the years ended December 31, 2019, 2018 and 2017, respectively, to other comprehensive loss in relation to such interest rate swap agreements. As of December 31, 2018, the fair value of such interest rate swap agreements were reflected as a $1.1 million liability (included in other current liabilities) in the accompanying consolidated balance sheets.

On August 13, 2015, CBRE Services issued $600.0 million in aggregate principal amount of 4.875% senior notes due March 1, 2026 at a price equal to 99.24% of their face value.

The 4.875% senior notes are redeemable at our option, in whole or in part, prior to December 1, 2025 at a redemption price equal to the greater of (1) 100% of the principal amount of the 4.875% senior notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon to December 1, 2025 (not including any portions of payments of interest accrued as of the date of redemption) discounted to the date of redemption on a semi-annual basis at the Adjusted Treasury Rate (as defined in the indenture governing these notes). In addition, at any time on or after December 1, 2025, the 4.875% senior notes may be redeemed by us, in whole or in part, at a redemption price equal

We funded this redemption with $550.0 million of borrowings from our tranche A term loan facility and $270.0 million of borrowings from our revolving credit facility under our 2017 Credit Agreement.

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 2019 Credit Agreement also requires us to maintain a minimum coverage ratio of consolidated EBITDA (as defined in the 2019 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 2019 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 2019 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 22.62x for the year ended December 31, 2019, and our leverage ratio of total debt less available cash to consolidated EBITDA was 0.44x as of December 31, 2019.

The 2019 Credit Agreement requires us to pay a fee based on the total amount of the revolving credit facility commitment (whether used or unused). As of December 31, 2019, no amount was outstanding under the revolving credit facility other than letters of credit totaling $2.0 million. 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.
