4. Long-Term Debt
    
   Long-term debt consists of the following:
    
   
 Interest expense was $3.1 million and $2.5 million for the three months ended June 30, 2011
   and 2010, respectively, and $6.4 million and $5.0 million for the six months ended June 30, 2011
   and 2010, respectively. Interest expense for the six months ended June 30, 2011 included a $0.9
   million write—off of unamortized deferred financing costs resulting from the extinguishment of the
   prior senior secured credit facility, or the Prior Credit Facility, as discussed below.
    
   On March 9, 2011, the Company entered into a $700.0 million senior secured revolving credit
   facility, or the New Credit Facility, with a syndicate of financial institutions as lenders and
   terminated its Prior Credit Facility, that consisted
   of a term loan and a revolving credit facility. The New Credit Facility has a five year maturity
   and expires on March 9, 2016. During March 2011, U.S. dollar borrowings under the New Credit
   Facility incurred interest at the base rate plus a margin of 0.75% or LIBOR plus a margin of 1.75%.
   After March 2011, based on the Company’s consolidated leverage ratio, U.S. dollar borrowings under
   the New 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 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 New Credit Facility. The New Credit Facility also permits the Company to
   borrow limited amounts in Mexican Peso and Euro currencies based on variable rates. The base rate
   under the New 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.
    
   In March 2011, the Company used $196.0 million in U.S. dollar borrowings under the New 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 New Credit Facility. These
   debt issuance costs were recorded as deferred financing costs on the Company’s condensed
   consolidated balance sheet and are being amortized over the term of the New Credit Facility. On
   June 30, 2011 and December 31, 2010, the weighted average interest rate for borrowings under the
   New Credit Facility and the Prior Credit Facility was 1.97% and 1.75%, respectively.
    
   The New Credit Facility requires the Company to comply with a leverage ratio and an interest
   coverage ratio. In addition, the New 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, 2011, the Company
   was compliant with its debt covenants.
    
   During the three months ended March 31, 2011, the Company borrowed $235.7 million and $54.0
   million under the New Credit Facility and Prior Credit Facility, respectively, and paid a total of
   $55.7 million and $228.9 million of the New Credit Facility and Prior Credit Facility,
   respectively. During the three months ended June 30, 2011, the Company borrowed $101.0 million
   under the New Credit Facility and paid a total of $123.0 million of the New Credit Facility. As of
   June 30, 2011, the U.S. dollar amount outstanding under the New Credit Facility was $158.0 million.
   There were no outstanding foreign currency borrowings as of June 30, 2011 under the New Credit
   Facility. As of December 31, 2010, the amounts outstanding under the Prior Credit Facility,
   consisting of a term loan and revolving facility, were $143.9 million and $31.0 million,
   respectively.
