On June 28, 2017, the Company entered into an amended and restated credit agreement (the “Amended and Restated Credit Agreement”) with the lenders named therein, JPMorgan Chase Bank, N.A. as administrative agent and certain other banks as co-syndication agents and co-documentation agents. The Amended and Restated Credit Agreement amended and restated the credit agreement dated April 17, 2014, among such parties (the “Original Credit Agreement”). The Amended and Restated Credit Agreement extends the applicable maturity date of the existing revolving credit facility (the “Revolving Credit Facility”) of $800.0 million to June 28, 2022 and re-evidences unsecured term loans at $400.0 million while also extending the applicable maturity date to June 28, 2022. The quarterly term loan principal amortization schedule was reset. At the time of the execution of the Amended and Restated Credit Agreement, $67.5 million of principal from the original unsecured term loans was repaid using operating cash balances, and the Company added an additional $2.8 million in debt issuance costs related to the Revolving Credit Facility to the Condensed Consolidated Balance Sheet. The Company also expensed to the Condensed Consolidated Statements of Income $0.2 million of debt issuance costs related to the Original Credit Agreement due to certain lenders exiting prior to execution of the Amended and Restated Credit Agreement. The Company also carried forward $1.6 million on the Condensed Consolidated Balance Sheet the remaining unamortized portion of the Original Credit Agreement debt issuance costs, which will be amortized over the term of the Amended and Restated Credit Agreement. On September 30, 2019, the Company made a scheduled principal payment of $10.0 million per the terms of the Amended and Restated Credit Agreement. As of September 30, 2019, there was an outstanding debt balance issued under the term loan of the Amended and Restated Credit Agreement of $340.0 million and $100.0 million borrowings outstanding against the Revolving Credit Facility. As of December 31, 2018, there was an outstanding debt balance issued under the term loan of the Amended and Restated Credit Agreement of $365.0 million with $350.0 million in borrowings outstanding against the Revolving Credit Facility. The Company had borrowed approximately $600.0 million under its Revolving Credit Facility on November 15, 2018 in connection with the closing of the acquisition of certain assets and assumption of certain liabilities of the Hays Companies. Per the terms of the Amended and Restated Credit Agreement, a scheduled principal payment of $10.0 million is due December 31, 2019.

On September 18, 2014, the Company issued $500.0 million of 4.200% unsecured Senior Notes due in 2024. The Senior Notes were given investment grade ratings of BBB-/Baa3 with a stable outlook. The notes are subject to certain covenant restrictions and regulations which are customary for credit rated obligations. At the time of funding, the proceeds were offered at a discount of the original note amount which also excluded an underwriting fee discount. The net proceeds received from the issuance were used to repay the outstanding balance of $475.0 million on the Revolving Credit Facility and for other general corporate purposes. As of September 30, 2019 and December 31, 2018, there was an outstanding debt balance of $500.0 million exclusive of the associated discount balance.

lead arrangers and joint bookrunners. The Term Loan Credit Agreement provides for an unsecured term loan in the initial amount of $300.0 million, which may, subject to lenders’ discretion, potentially be increased up to an aggregate amount of $450.0 million (the “Term Loan”). The Term Loan is repayable over the five-year term from the effective date of the Term Loan Credit Agreement, which was December 21, 2018. Based on the Company’s net debt leverage ratio or a non-credit enhanced senior unsecured long-term debt rating as determined by Moody’s Investor Service and Standard & Poor’s Rating Service, the rates of interest charged on the term loan are 1.00% to 1.75%, above the adjusted 1-Month LIBOR rate. On December 21, 2018, the Company borrowed $300.0 million under the Term Loan Credit Agreement and used $250.0 million of the proceeds to reduce indebtedness under the Company’s Amended and Restated Credit Agreement, dated June 28, 2017, with the lenders named therein, JPMorgan Chase Bank, N.A., as administrative agent, and certain other banks as co-syndication agents and co-documentation agents (the “Revolving Credit Facility”). As of September 30, 2019, there was an outstanding debt balance issued under the Term Loan of $288.8 million. As of December 31, 2018, there was an outstanding debt balance issued under the Term Loan of $300.0 million.

As of September 30, 2019, there was an outstanding debt balance of $350.0 million exclusive of the associated discount balance.

The Amended and Restated Credit Agreement and Term Loan Credit Agreement require the Company to maintain certain financial ratios and comply with certain other covenants. The Company was in compliance with all such covenants as of September 30, 2019 and December 31, 2018.
