The Company has the ability to prepay the term loan before its maturity date. Interest is payable on the term loan at 4 1/2% per annum, payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year. The term loan contains covenants restricting, among other things, the incurrence of indebtedness and the making of certain payments, including dividends, and is subject to acceleration in the event of default. The Company also has to fulfill financial covenants with respect to a total debt to EBITDA ratio and an interest coverage ratio. Credit Facility The Company’s revolving credit and term loan facility consists of an $800.0 million multi-currency revolving credit facility and a €312.0 million (or approximately $338.9 million as of December 31, 2015) term loan facility. The Company is not required to make quarterly payments towards the term loan facility. On June 19, 2015, the Company amended its current credit facility agreement, providing the Company with the ability to replace the current term loan facility denominated in United States dollars with an equivalent amount denominated in Euros. In August 2015, the Company replaced the outstanding term loan facility in the amount of $355.0 million, denominated in U.S. dollars, with an equivalent amount denominated in Euros. The Company also extended the maturity date of the credit facility from June 28, 2019 to June 26, 2020 and amended the interest rate margin. Under the amended credit facility agreement, interest accrues on amounts outstanding, at the Company’s option, depending on the currency borrowed, at either (1) LIBOR or EURIBOR plus a margin ranging from 1.0% to 1.75% based on the Company’s leverage ratio, or (2) the base rate, which is equal to the higher of (i) the administrative agent’s base lending rate for the applicable currency, (ii) the federal funds rate plus 0.5%, and (iii) one-month LIBOR for loans denominated in U.S. dollars plus 1.0% plus a margin ranging from 0.0% to 0.25% based on the Company’s leverage ratio. Previously, the interest accrued on amounts outstanding under the credit facility, at the Company’s option, at either (1) LIBOR plus a margin ranging from 1.0% to 2.0% based on the Company’s leverage ratio, or (2) the base rate, which is equal to the higher of (i) the administrative agent’s base lending rate for the applicable currency, (ii) the federal funds rate plus 0.5%, and (iii) one-month LIBOR for loans denominated in U.S. dollars plus 1.0% plus a margin ranging from 0.0% to 0.5% based on the Company’s leverage ratio. As is more fully described in Note 11, the Company entered into an interest rate swap in August 2015 to convert the term loan facility’s floating interest rate to a fixed interest rate of 0.33% plus the applicable margin over the remaining life of the term loan facility. The credit facility contains covenants restricting, among other things, the incurrence of indebtedness and the making of certain payments, including dividends, and is subject to acceleration in the event of a default. The Company also has to fulfill financial covenants with respect to a total debt to EBITDA ratio and an interest coverage ratio. As of December 31, 2015, no amounts were outstanding under the Company’s multi-currency revolving credit facility, and the Company had the ability to borrow approximately $800.0 million under the facility. Approximately €312.0 million (or approximately $338.9 million) was outstanding under the term loan facility as of December 31, 2015. As of December 31, 2014, the Company had $404.4 million of outstanding borrowings under its former credit facility and availability to borrow approximately $750.6 million. Approximately $49.4 million was outstanding under the multi-currency revolving credit facility and $355.0 million was outstanding under the term loan facility as of December 31, 2014. During 2015, the Company designated its €312.0 million ($338.9 million at December 31, 2015) term loan facility as a hedge of its net investment in foreign operations to offset foreign currency translation gains or losses on the net investment. See Note 11 for additional information about the net investment hedge. 1.056% Senior Term Loan In December 2014, the Company entered into a term loan with the European Investment Bank, which provided the Company with the ability to borrow up to €200.0 million. The €200.0 million (or approximately $217.2 million as of December 31, 2015) of funding was received on January 15, 2015 with a maturity date of January 15, 2020. The Company has the ability to prepay the term loan before its maturity date. Interest is payable on the term loan at 1.056% per annum, payable quarterly in arrears on January 15, April 15, July 15 and October 15 of each year. The term loan contains covenants regarding, among other things, the incurrence of indebtedness and the making of certain payments, as well as commitments regarding amounts of future research and development expenses in Europe, and is subject to acceleration in the event of default. The Company also has to fulfill financial covenants with respect to a net leverage ratio and an interest coverage ratio. 5 7/8% Senior Notes The Company’s $297.4 million of 5 7/8% senior notes due December 1, 2021 constitute senior unsecured and unsubordinated indebtedness. Interest is payable on the notes semi-annually in arrears on June 1 and December 1 of each year. At any time prior to September 1, 2021, the Company may redeem the notes, in whole or in part from time to time, at its option, at a redemption price equal to the greater of (i) 100% of the principal amount plus accrued and unpaid interest, including additional interest, if any, to, but excluding, the redemption date or (ii) the sum of the present values of the remaining scheduled payments of principal and interest (exclusive of interest accrued to the date of redemption) discounted to the redemption date at the treasury rate plus 0.5%, plus accrued and unpaid interest, including additional interest, if any. Beginning September 1, 2021, the Company may redeem the notes, in whole or in part from time to time, at its option, at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest, including additional interest, if any. As is more fully described in Note 11, the Company entered into an interest rate swap in August 2015 to convert the senior notes’ fixed interest rate to a floating interest rate over the remaining life of the senior notes. A weighted average interest rate of 4.53% was applicable from the date of inception of the interest rate swap to December 31, 2015. Former Convertible Senior Subordinated Notes During the first six months of 2014, holders of the Company’s former 1 1/4% convertible senior subordinated notes converted or the Company repurchased approximately $49.7 million of aggregate principal amount of the notes. In May 2014, the Company announced its election to redeem the remaining $151.5 million balance of the notes with a redemption date of June 20, 2014. Substantially all of the holders of the notes elected to convert their remaining notes prior to the redemption date. The redemptions settled in July 2014. For the year ended December 31, 2014, the Company issued a total of 1,437,465 shares of its common stock associated with the $81.0 million excess conversion value of all notes converted.
