REVOLVING CREDIT FACILITY	5. REVOLVING CREDIT FACILITY On August 22, 2011, WESCO Distribution, Inc. (“WESCO Distribution”) entered into a new Revolving Credit Facility, which has an aggregate borrowing capacity of $400 million and includes a letter of credit sub-facility of up to $80 million. The Revolving Credit Facility consists of two separate sub-facilities: (i) a U.S. sub-facility with a borrowing limit at any given time of up to $400 million less the amount of outstanding borrowings under the Canadian sub-facility at that time and (ii) a Canadian sub-facility with a borrowing limit of up to $175 million. The new facility also contains an accordion feature, allowing WESCO Distribution to request increases to the borrowing commitments under the facility of up to $100 million in the aggregate. The facility matures in August 2016 and is collateralized by the inventory and certain other assets of WESCO Distribution and certain of its domestic subsidiaries and the inventory, accounts receivable, and certain other assets of WESCO Distribution Canada, L.P. WESCO Distribution’s obligations under the Revolving Credit Facility have been guaranteed by WESCO International, Inc. (“WESCO International”) and by certain of WESCO International’s subsidiaries. The completion of the new facility resulted in $1.8 million of accelerated amortization expense related to the deferred financing fees from the previous facility. Availability under the facility is based upon the amount of eligible U.S. and Canadian inventory and Canadian receivables applied against certain advance rates. Depending upon the amount of excess availability under the facility, interest will be calculated at LIBOR plus a margin that ranges between 1.50% and 2.00% or at the Alternative Rate (prime rate) plus a margin that ranges between 0.50% and 1.00%. The interest rate margin is reduced by 0.25% if WESCO’s leverage ratio, as calculated under the Revolving Credit Facility, falls below a ratio of 2.5 to 1.0. As long as the pro forma combined availability for the preceding 60-day period, up to and including the transaction date, under the facility and WESCO Distribution’s accounts receivable securitization facility (the “Receivables Facility”) is greater than $125 million, WESCO is permitted, subject to certain specified conditions, to make acquisitions and repurchase WESCO International’s outstanding capital stock and WESCO outstanding indebtedness. At September 30, 2011, there were no borrowings outstanding under the facility.
