Senior Secured Credit Facility

The Company has a senior secured credit facility, referred to as the Credit Facility. Under the Credit Facility, aggregate borrowing commitments total approximately $1.25 billion, composed of $1.0 billion of revolving commitments and a term loan in the principal amount of $247 million (the “Term Loan”). As of March 31, 2016 and December 31, 2015, outstanding revolving loans under the Credit Facility accrued interest at weighted average rates of approximately 3.38% and 2.95% per annum, respectively, and the Term Loan accrued interest at a rate of 2.43% and 2.42% as of March 31, 2016 and December 31, 2015, respectively. Letters of credit of approximately $403.8 million and $292.8 million were issued as of March 31, 2016 and December 31, 2015, respectively. As of both March 31, 2016 and December 31, 2015, letter of credit fees accrued at 1% per annum for performance standby letters of credit and at 2% for financial standby letters of credit. Outstanding letters of credit mature at various dates and most have automatic renewal provisions, subject to prior notice of cancellation. As of March 31, 2016 and December 31, 2015, borrowing capacity of $365.3 million and $498.7 million, respectively, was available for revolving loans, or up to $46.2 million and $157.2 million, respectively, for new letters of credit. Borrowing capacity as of March 31, 2016 and December 31, 2015 included $104.6 million and $111.8 million, respectively, of availability in either Canadian dollars or Mexican pesos. The unused facility fee was 0.40% as of both March 31, 2016 and December 31, 2015. The Credit Facility is guaranteed by certain subsidiaries of the Company (the “Guarantor Subsidiaries”), and the obligations under the Credit Facility are secured by substantially all of the Company’s and the Guarantor Subsidiaries’ respective assets, subject to certain exceptions.

Other Credit Facilities. The Company has other credit facilities that support the working capital requirements of its foreign operations. Borrowings under these credit facilities, which have varying dates of maturity and are generally renewed on an annual basis, are primarily denominated in Canadian dollars. Maximum borrowing capacity totaled Canadian $40.0 million as of both March 31, 2016 and December 31, 2015, or approximately $30.8 million and $28.9 million, respectively. Outstanding borrowings totaled approximately $14.9 million and $16.4 million as of March 31, 2016 and December 31, 2015, respectively. Outstanding borrowings accrued interest at a weighted average rate of 3.6% as of both March 31, 2016 and December 31, 2015. Outstanding borrowings that are not renewed are repaid with borrowings under the Credit Facility. Accordingly, the carrying amounts of the Company’s borrowings under its other credit facilities are classified within long-term debt in the Company’s consolidated balance sheets. The Company’s other credit facilities are subject to customary provisions and covenants.
