Commenting on today's announcement, Joseph D. Vecchiolla, Bird's Chairman stated that, "Bird has enjoyed a rich and innovative history since its founding over 200 years ago. However, during the past year it became apparent that greater progress could be made if Bird became part of a larger, financially strong orqanization with similar goals and philosophies. The agreement reached with CertainTeed is the culmination of several months of negotiations with a number of candidates and meets our criteria. There is an excellent fit between our organizations, as we are both producers of high quality asphalt roofing shingles. Integrating Bird's resources with CertainTeed will strengthen our core manufacturing operations". Bird Corporation, founded in 1795, is primarily a manufacturer of asphalt shingles and roll-roofing goods with annual sales of more than $50 million.
