In September 2019, the Company issued $700 million of unsecured senior notes (“2019 Notes”) in a registered public offering. The 2019 Notes are due in 2029 with a coupon rate of 3.25%. The Company used the proceeds from the 2019 Notes offering to repay in full a $350 million term loan and to pay down outstanding balances under our revolving credit facility. The Company expects to repay or refinance the 3.000% Senior Notes prior to the June 2020 maturity date.

In April 2020, the Company entered into a 364-day, $400 million revolving credit facility (the “2020 Revolving Credit Agreement”), and borrowings thereunder will be used for general corporate purposes. Given the uncertain nature and duration of the COVID-19 pandemic, this was a proactive step taken out of an abundance of caution to provide ample liquidity for the business. The terms and conditions of the 2020 Revolving Credit Agreement are essentially the same as the Company’s existing $1.25 billion revolving credit facility except for additional provisions related to cash hoarding and the use of debt issuance proceeds. Interest rates under the 2020 Revolving Credit Agreement are variable based on LIBOR at the time of the borrowing and the Company’s long-term credit rating and can range from LIBOR + 1.40% to LIBOR + 1.8%. The 2020 Revolving Credit Agreement includes a covenant under which the Company is required to maintain a minimum ratio of consolidated EBITDA to consolidated interest expense of 3.0 to 1.0. Consolidated EBITDA is defined as consolidated net income before interest expense, income taxes, depreciation, amortization of intangible assets, losses from asset impairments, and certain other one-time adjustments. In addition, the 2020 Revolving Credit Agreement includes a covenant under which the Company’s ratio of consolidated total indebtedness minus certain cash and cash equivalents to consolidated EBITDA generally may not exceed 3.5 to 1.0.

In September 2019, the Company entered into a second amended and restated $1.25 billion revolving credit facility (the “2019 Revolving Credit Agreement”), and borrowings thereunder will be used for general corporate purposes. The terms and conditions of the 2019 Revolving Credit Agreement, including the total commitment amount, essentially remained the same as under the previous credit agreement, except that the maturity date was extended to September 2024. Borrowings amounting to $165.0 million were rolled-over from the prior revolving credit facility into the 2019 Revolving Credit Agreement. Interest rates under the 2019 Revolving Credit Agreement are variable based on LIBOR at the time of the borrowing and the Company’s long-term credit rating and can range from LIBOR + 0.91% to LIBOR + 1.4%. This amendment and restatement of the credit agreement was a non-cash transaction for the Company. On March 31, 2020, our outstanding borrowings under this facility was $250.0 million. On December 31, 2019, our outstanding borrowings under this facility was zero. This facility is included in Long-term debt in the condensed consolidated balance sheets. As of March 31, 2020, we were in compliance with all covenants under this facility.

In September 2019, the Company used the proceeds from the 2019 Notes to repay the full outstanding balance on the Term Loan entered into in March 2018 and subsequently amended in August 2018 and March 2019 (the “Term Loan”). Following the March 2019 amendment, the Term Loan provided for borrowings of $350 million and matured in March 2020. At March 31, 2020 and December 31, 2019, amounts due under the Term Loan were zero.

We currently have uncommitted bank lines of credit in China, which provide for unsecured borrowings for working capital of up to $17.5 million in aggregate, of which there were no outstanding balances as of March 31, 2020 and December 31, 2019.
