Young will step down from the Phoenix board and serve as a consultant to the company for one year, Phoenix says.

Wehr’s financial markets experience should be helpful at helping him lead Phoenix during current conditions, Browning says.

“My entire career has been at Phoenix, which made this a particularly difficult decision,” Young says in a statement of her own. “Ultimately, however, I determined that it was the right time to make the change for the company and for my family. Obviously, the past several months have been challenging as never before, and Jim Wehr’s deep market expertise has been invaluable. Clearly, Jim is ready to lead the company at this critical point in its history. The management team is deep and strong, and the board is experienced and resourceful. I look forward to working with Jim and the board to assure a seamless transition and as a consultant for the next year.”
