ELK Elkcorp

ElkCorp (NYSE:ELK) subsidiary Elk Premium Building Products, Inc. (Elk), received the "Partners of Choice" double "A" award for outstanding quality and service from David Weekley Homes (Weekley), the nation's third largest privately held home builder. The double "A" distinction is the highest award given by the Weekley team members in its National Trading Partners Survey. Approximately 150 suppliers were rated, but only nine received the "AA" distinction. Elk was the only roofing products company to achieve this status this year. "Elk has demonstrated they are among the best of the best," said David Weekley Homes Vice President of Supply Chain Services Bill Justus. "This award is extremely difficult to earn because you are evaluated by potentially 1,000 of our team members in all our markets, and at all levels within our company. For a manufacturer, it requires you to take ownership of the supply chain through the delivery and installation of products into our homes. Elk's performance in this survey proves our faith in our relationship is well-founded." The National Trading Partner Survey is sent quarterly to over 250 team members at every level in the Weekley organization (1,000 annually). Companies are rated on quality, service, product training and supplier relations. Each company is assigned a numeric score ranging from "A" to "F." "Through this evaluation process, David Weekley Homes clearly demonstrates its high quality standard that is translated directly from its supplier partners to the homeowner," said ElkCorp Senior Vice President of Sales and Marketing Curt Barker. "Our customers know they can have confidence in Elk to manufacture the highest quality products sold by the highest quality people. We share this award with our sales force, manufacturing plants and supply chain partners." Elk has maintained a strong relationship with Weekley for over sixteen years and continues to be its largest supplier of roofing materials.
