[1] On April 3, 2012, we entered into a term loan agreement (the ''Term Loan Agreement'') that provides for a 4-year term loan facility of $300 million, composed of one $150 million borrowing and one Euro-denominated borrowing equal to $150 million at issuance (or €120 million borrowing) both of which were funded upon close of the Acquisition on June 15, 2012. The Term Loan Agreement required quarterly principal repayments equal to 2.5% of the initial principal obligation, which commenced on September 30, 2012, with the remaining 62.5% principal balance due at the June 15, 2016 maturity date. The obligations under the Term Loan Agreement were our general unsecured obligations. The Term Loan Agreement contained customary events of default, specified representations and warranties and covenants, including, among other things, covenants that limited our and our subsidiaries' ability to incur certain additional priority indebtedness, create or permit liens on assets or engage in mergers or consolidations. Debt issuance costs capitalized in connection with the Term Loan Agreement were amortized over the life of the debt and totaled approximately $3 million.During 2012, we repaid the $150 million borrowing and made principal repayments of €26.0 million on the €120 million borrowing. During the third quarter of 2012, we designated the €120 million term loan as a net investment hedge of our Central European operations. During 2013, we made principal repayments of $123.8 million (€93.7 million) on the remaining balance of our €120 million term loan. As a result, the term loan was fully repaid in the third quarter of 2013. See Note 17, "Derivative Instruments and Hedging Activities" for further discussion.
