7.	External Debt and Financing Arrangements

In June 2016, the Company amended and restated its credit agreement to combine and rollover the existing revolving credit facility and term loan into a new standalone $1.25 billion revolving credit facility. This amendment of the credit agreement was a non-cash transaction for the Company. Terms and conditions of the credit agreement, including the total commitment amount as of June 30, 2016, essentially remain the same. The revolving credit facility matures in June 2021 and borrowings thereunder will be used for general corporate purposes. On June 30, 2016 and December 31, 2015, our outstanding borrowings under these facilities, net of debt issuance costs relating to the term loan balance, were $710.0 million and $279.0 million, respectively. At June 30, 2016 and December 31, 2015, the current portion of long-term debt 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 June 30, 2016, we were in compliance with all covenants under this facility. As a result of the refinancing, we wrote-off prepaid debt issuance costs of approximately $1.3 million during the quarter. We retrospectively adopted ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs,” on January 1, 2016, resulting in the reclassification of approximately $3 million of debt issuance costs from other current assets and other assets to long-term debt as of December 31, 2015. Adoption of this new guidance did not impact the Company’s equity, results of operations or cash flows.

In June 2015, we issued $900 million of unsecured senior notes (“Senior Notes”) in a registered public offering. The Senior Notes consist of two tranches: $400 million of five-year notes due 2020 with a coupon of 3% and $500 million of ten-year notes due 2025 with a coupon of 4%. We used the proceeds from the Senior Notes offering to pay down our revolving credit facility and for general purposes. On June 30, 2016 and December 31, 2015, the net carrying value of the Senior Notes, net of underwriting commissions, price discounts and debt issuance costs, was $890.4 million and $889.7 million, respectively.

We currently have uncommitted bank lines of credit in China, which provide for unsecured borrowings for working capital of up to $25.7 million in aggregate, of which $3.2 million and $0.8 million were outstanding, as of June 30, 2016 and December 31, 2015, respectively. The weighted-average interest rates on these borrowings were 1.2% and 1.1% in the six and three-month periods ended June 30, 2016, respectively. There were no borrowings in the six and three-month periods ended June 30, 2015.

During the second quarter of 2016, the Company identified an immaterial prior period misstatement related to the classification of issuances and repayments of long-term debt within cash flows from financing activities in our Consolidated Statement of Cash Flows for the first quarter of 2016. As a result, the Consolidated Statement of Cash Flows for the six months ended June 30, 2016 reflects an increase in issuances of long-term debt and corresponding increase in repayments of long-term debt of $60 million to present long-term debt cash flows on a gross basis. The misstatement does not have any impact on total cash flows from financing activities. The corresponding cash flow line items in the first quarter 2016 cash flow statement will be revised prospectively as the misstatement was considered to be immaterial.
