ARC funds these purchases with borrowings from participating lenders under a loan agreement. This program also includes a letter of credit facility pursuant to which ARC may request the issuance of letters of credit issued for the company’s U.S. subsidiaries (originators) or their designees, which when issued will constitute a utilization of the facility for the amount of letters of credit issued.
