"We are delighted to welcome Austin Adams to D&B's Board of Directors," said Steve Alesio, D&B's Chairman and CEO.

"In our more recent past, he provided guidance in the development of our Blue-print for Growth strategy and added value in our thoughtful succession planning as Chair of the Compensation & Benefits Committee. I'd personally like to thank Ron for his wonderful service and dedication to D&B and his guidance to its leaders over time."
