On March 31, 2017, CDW LLC (“CDW”) amended, extended and increased the size of its senior secured asset-based revolving credit facility. The terms of the revolving credit facility are set forth in the Second Amended and Restated Revolving Loan Credit Agreement, dated March 31, 2017, by and among CDW, the lenders party thereto, JPMorgan Chase Bank, N.A., as administrative agent, Wells Fargo Commercial Distribution Finance, LLC, as floorplan funding agent, and the joint lead arrangers, joint bookrunners, co-collateral agents, co-syndication agents and co-documentation agents party thereto (the “Second A&R Revolving Loan Agreement”). The Second A&R Revolving Loan Agreement amends and restates CDW’s prior revolving loan credit agreement, dated June 6, 2014, by and among CDW, the lenders party thereto, JPMorgan Chase Bank, N.A., as administrative agent, Wells Fargo Commercial Distribution Finance, LLC, as floorplan funding agent, and the joint lead arrangers, joint bookrunners, co-collateral agents, co-syndication agents and co-documentation agents party thereto, as previously amended, modified and supplemented. Borrowings under the revolving credit facility will continue to bear interest at a variable interest rate (based on one of two indices, either LIBOR or an alternate base rate outlined in the Second A&R Revolving Loan Agreement) plus an applicable margin based upon average daily excess cash availability.

The Second A&R Revolving Loan Agreement, among other things, (i) increases the overall revolving credit facility from $1,250.0 million to $1,450.0 million, (ii) extends the maturity date from June 6, 2019 to March 31, 2022, and (iii) eliminates the ratings-based adjustment to the pricing grid, providing for interest rate margins at the reduced interest rate margins previously applicable only if CDW satisfied the ratings-based requirement.

CDW’s ability to borrow under the revolving credit facility remains limited by a minimum liquidity condition, which continues to provide that, if excess cash availability is less than the lesser of (i) $125.0 million and (ii) the greater of (A) 10% of the borrowing base and (B) $100.0 million, the lenders are not required to lend any additional amounts under the revolving credit facility unless the consolidated fixed charge coverage ratio (as described in the Second A&R Revolving Loan Agreement) is at least 1.00 to 1.00.

The descriptions of the Second A&R Revolving Loan Agreement contained in this Current Report on Form 8-K are qualified in their entirety by reference to the complete text of the Second A&R Revolving Loan Agreement, a copy of which is filed herewith as Exhibit 10.1, which is incorporated herein by reference.

The discussion of the Second A&R Revolving Loan Agreement set forth under Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.
