4. Long-Term Debt

Long-term debt consists of the following:

On March 9, 2011, the Company entered into a $700.0 million senior secured revolving credit facility, or the Credit Facility, with a syndicate of financial institutions as lenders and terminated its prior senior secured credit facility, or the Prior Credit Facility. The Credit Facility has a five year maturity and expires on March 9, 2016. Based on the Company’s consolidated leverage ratio, U.S. dollar borrowings under the Credit Facility bear interest at either LIBOR plus the applicable margin between 1.50% and 2.50% or the base rate plus the applicable margin between 0.50% and 1.50%. The base rate under the Credit Facility represents the highest of the Federal Funds Rate plus 0.50%, one-month LIBOR plus 1.00%, and the prime rate offered by Bank of America. The Company, based on its consolidated leverage ratio, pays a commitment fee between 0.25% and 0.50% per annum on the unused portion of the Credit Facility. The Credit Facility also permits the Company to borrow limited amounts in Mexican Peso and Euro currencies based on variable rates.

In March 2011, the Company used $196.0 million in U.S. dollar borrowings under the Credit Facility to repay all amounts outstanding under the Prior Credit Facility. The Company incurred approximately $5.7 million of debt issuance costs in connection with the Credit Facility. These debt issuance costs were recorded as deferred financing costs on the Company’s consolidated balance sheet and are being amortized over the term of the Credit Facility.

On July 26, 2012, the Company amended the Credit Facility to include a $500.0 million term loan with a syndicate of financial institutions as lenders, or the Term Loan. The Term Loan is a part of the Credit Facility and is in addition to the Company’s current revolving credit facility. The Term Loan matures on March 9, 2016. The Company will make regular scheduled payments for the Term Loan consisting of both principal and interest components. Based on the Company’s consolidated leverage ratio, the Term Loan bears interest at either LIBOR plus the applicable margin between 1.50% and 2.50% or the base rate plus the applicable margin between 0.50% and 1.50% which are the same terms as the Company’s revolving credit facility.

In July 2012, the Company used all $500.0 million of the borrowings under the Term Loan to pay down amounts outstanding under the Company’s revolving credit facility. The Company incurred approximately $4.5 million of debt issuance costs in connection with the Term Loan. The debt issuance costs are recorded as deferred financing costs on the Company’s consolidated balance sheet and will be amortized over the life of the Term Loan. On June 30, 2013 and December 31, 2012, the weighted average interest rate for borrowings under the Credit Facility, including borrowings under the Term Loan, was 2.20% and 1.96%, respectively.

The Credit Facility requires the Company to comply with a leverage ratio and a coverage ratio. In addition, the Credit Facility contains customary covenants, including covenants that limit or restrict the Company’s ability to incur liens, incur indebtedness, make investments, dispose of assets, make certain restricted payments, pay dividends, repurchase its common shares, merge or consolidate and enter into certain transactions with affiliates. As of June 30, 2013 and December 31, 2012, the Company was compliant with its debt covenants under the Credit Facility. The fair value of the outstanding borrowings on the Company’s revolving credit facility and Term Loan approximated their carrying values as of June 30, 2013, due to their variable interest rates which reprice frequently and represent floating market rates. The fair value of the outstanding borrowings on the Company’s revolving credit facility and Term Loan are determined by utilizing Level 2 inputs as defined in Note 12, Fair Value Measurements, such as observable market interest rates and yield curves.

During the three months ended March 31, 2013, the Company borrowed an aggregate amount of $513.0 million and paid a total amount of $25.5 million under the Credit Facility. During the three months ended June 30, 2013, the Company paid a total amount of $12.5 million under the Credit Facility. The Company did not make any borrowings under the Credit Facility during the three months ended June 30, 2013. As of June 30, 2013 and December 31, 2012, the U.S. dollar amount outstanding under the Credit Facility was $962.5 million and $487.5 million, respectively. Of the $962.5 million U.S. dollar amount outstanding under the Credit Facility as of June 30, 2013, $462.5 million was outstanding on the Term Loan and $500.0 million was outstanding on the revolving credit facility. Of the $487.5 million U.S. dollar amount outstanding under the Credit Facility as of December 31, 2012, $487.5 million was outstanding on the Term Loan and no amounts were outstanding on the revolving credit facility. There were no outstanding foreign currency borrowings as of June 30, 2013 and December 31, 2012 under the Credit Facility.

As of June 30, 2013, the aggregate annual maturities of the Credit Facility were expected to be $31.3 million for 2013, $81.2 million for 2014, $100.0 million for 2015, and $750.0 million for 2016.

Interest expense was $7.5 million and $4.5 million for the three months ended June 30, 2013 and 2012, respectively, and $14.3 million and $7.3 million for the six months ended June 30, 2013 and 2012, respectively.
