As a result of the adoption of new accounting guidance effective January 1, 2016, on a retrospective basis, unamortized debt issuance costs are now deducted from the carrying amount of the associated debt liability on the balance sheet. The reclassification of these unamortized debt issuance costs resulted in reductions of $17.1 million in Long-term debt and Other assets on the condensed consolidated balance sheets as of December 31, 2015. See Note 18, “Recently Issued Accounting Pronouncements,” for additional information.

Initial borrowings under our September 2015 Term Loan Agreement, which occurred on October 15, 2015, consisted of a 364-day term loan facility in an aggregate principal amount of $300 million (the “364-Day Facility”) and a five-year term loan facility in an aggregate principal amount of $950 million (the “Five-Year Facility”), or collectively, the “Term Loan Facilities.” In the three-month period ended March 31, 2016, we repaid the 364-Day Facility in full and repaid approximately $31 million of borrowings under the Five-Year Facility, each primarily with proceeds from the sales of the metal sulfides business and the minerals-based flame retardants and specialty chemicals businesses, both of which closed in the first quarter of 2016.

Current portion of long-term debt at March 31, 2016 consists primarily of commercial paper notes with a weighted-average interest rate of approximately 1.31% and a weighted-average maturity of 21 days.

The carrying value of our 1.875% Euro-denominated senior notes has been designated as an effective hedge of our net investment in foreign subsidiaries where the Euro serves as the functional currency, and gains or losses on the revaluation of these senior notes to our reporting currency are recorded in accumulated other comprehensive loss. During the three-month periods ended March 31, 2016 and 2015, (losses) gains of ($9.5) million and $54.0 million (net of income taxes), respectively, were recorded in accumulated other comprehensive loss in connection with the revaluation of these senior notes to our reporting currency.
