We are assigning our preliminary 'BB-' corporate credit rating to U.S.-based American Builders&Contractors Supply Co. At the same time we are assigning our preliminary 'BB+' issue-level rating and preliminary '1' recovery rating to the company's proposed $1.150 billion senior secured term loan B, and a preliminary 'B' issue-level rating and preliminary '6' recovery rating to its proposed $600 million senior unsecured notes. Our stable outlook reflects our view that a stronger new home construction market will boost sales of ABC Supply Co.'s roofing products, siding, windows, and other materials from an already solid base and that some of this cash flow will be used to repay debt such that leverage will drop to about 4.5x by the end
