12. Long-term debt

In August 2012, the Company obtained credit facilities aggregating $925,000 from a consortium of financial institutions.

In June 2013, the Company amended this credit facility to reduce interest payments thereunder. As of the amendment date, the gross outstanding term loan amounted to $671,625. The amendment did not result in a substantial modification of $553,589 of the outstanding term loan under the previous credit facility. As a result of the amendment, the Company extinguished $118,036 of the outstanding term loan under the previous facility and obtained additional funding amounting to $121,410, increasing the total term loan outstanding to $675,000. The Company expensed $3,103, representing partial acceleration of the amortization of the existing unamortized debt issuance costs and an additional fee paid to the lenders in respect of the extinguished amount. The overall borrowing capacity under the revolving facility did not change. The amendment of the revolving facility resulted in accelerated amortization of $54 relating to the existing unamortized debt issuance cost. The remaining unamortized costs and an additional third party fee paid in connection with the amendment were to be amortized over the duration of the term loan and revolving facility, which by their terms were to expire on August 30, 2019 and August 30, 2017, respectively.

In June 2015, the Company refinanced its 2012 facility through a new credit facility, comprised of an $800,000 term loan and a $350,000 revolving credit facility. Borrowings under the new facility bear interest at a rate equal to, at the election of the Company, either LIBOR plus an applicable margin equal to 1.50% per annum or a base rate plus an applicable margin equal to 0.50% per annum, in each case subject to adjustment based on the Company’s debt ratings provided by Standard & Poor’s Rating Services and Moody’s Investors Service, Inc. Based on the Company’s election and current credit rating, the applicable interest rate is equal to LIBOR plus 1.50% per annum. As a result of the June 2015 refinancing, the gross outstanding term loan under the previous facility, which amounted to $663,188 as of June 30, 2015, was extinguished, and the Company expensed $10,050, representing accelerated amortization of the existing unamortized debt issuance costs related to the prior facility. Additionally, the refinancing of the revolving facility resulted in the accelerated amortization of $65 relating to the existing unamortized debt issuance cost. The remaining unamortized costs for the revolving facility, together with the fees paid to the Company’s lenders and third parties in connection with the new term loan and revolving facility, will be amortized over the term of the refinanced facility, which ends on June 30, 2020.

As of December 31, 2015 and March 31, 2016, the amount outstanding under the term loan, net of debt amortization expense of $3,534 and $3,314, was $776,466 and $766,686, respectively. As of December 31, 2015 and March 31, 2016, the term loan bore interest at a rate equal to LIBOR plus a margin of 1.50% per annum. Indebtedness under the refinanced facility is unsecured. The amount outstanding on the term loan as of March 31, 2016 will be repaid through quarterly payments of $10,000, and the balance will be repaid upon the maturity of the term loan on June 30, 2020.

The maturity profile of the term loan, net of debt amortization expense, is as follows:
