In September 2018, we issued $600 million of unsecured senior notes (“2018 Senior Notes”) in a registered public offering. The 2018 Senior Notes are due in 2023 with a coupon rate of 4%. All other terms and conditions of the 2018 Senior Notes are substantially consistent with the 2015 Senior Notes. We used the proceeds from the 2018 Senior Notes offering to pay down our revolving credit facility. On December 31, 2018, the net carrying value of the 2018 Senior Notes, net of underwriting commissions, price discounts, and debt issuance costs, was $595.0 million.

In June 2015, we issued $900 million of unsecured senior notes (“2015 Senior Notes”, and collectively with the 2018 Senior Notes, the “Senior Notes”) in a registered public offering. The 2015 Senior Notes consist of two tranches: $400 million of five-year notes due in 2020 with a coupon rate of 3% and $500 million of

ten-

year

notes due in 2025 with a coupon rate of 4%. We used the proceeds from the 2015 Senior Notes offering to pay down our revolving credit facility and for general corporate purposes. On December 31, 2018 and December 31, 2017, the net carrying value of the 2015 Senior Notes, net of underwriting commissions, price discounts, and debt issuance costs, was $894.0 million and $892.6 million, respectively.

In March 2018, the Company entered into a $350 million term loan for general corporate purposes that matures in March 2019. In August 2018, the Company amended its existing $350 million term loan to increase the borrowings under the term loan from $350 million to $525 million. All other terms and conditions on the amended term loan remain the same as the previous $350 million term loan. Interest rates under the term loan are variable based on LIBOR at the time of the borrowing and the Company’s long-term credit rating and can range from LIBOR + 0.625% to LIBOR + 1.25%. Covenants under the term loan are the same as the existing $1.25 billion revolving credit agreement. As of December 31, 2018, we were in compliance with all covenants under this term loan.

In June 2016, the Company amended and restated its credit agreement to combine and rollover the 2011 revolving credit facility and term loan into a new standalone $1.25 billion revolving credit facility. The amendment and restatement was a

non-cash

transaction for the Company. Terms and conditions of the credit agreement, including the total commitment amount, essentially remained the same. The revolving credit facility will mature in June 2021 and borrowings thereunder will be used for general corporate purposes. On December 31, 2018 and December 31, 2017, our outstanding borrowings under this facility were $320.0 million and $615.0 million, respectively. At December 31, 2018 and December 31, 2017, the current portion of long-term debt under this facility was zero. Interest rates under the facility are variable based on LIBOR at the time of the borrowing and the Company’s long-term credit rating and can range from LIBOR + 0.9% to LIBOR + 1.5%. As of December 31, 2018, we were in compliance with all covenants under this facility.

We currently have uncommitted bank lines of credit in China, which provide for unsecured borrowings for working capital of up to $23.5 million in aggregate, of which zero were outstanding, as of December 31, 2018 and 2017. The weighted-average interest rates on these borrowings were zero in 2018 and 2017.

In our debt agreements, there are normal and customary events of default which would permit the lenders to accelerate the debt if not cured within applicable grace periods, such as failure to pay principal or interest when due or a change in control of the Company. There were no events of default as of December 31, 2018.
