He was named co-chairman of the merged company in 2003 and chairman in 2004. Pollard is retiring to spend more time with his family and to focus on other endeavors.   “After much thought and nearly 15 years as a board member at UnumProvident, I believe the time has come for me to step down and move on to other priorities in my life,” said Pollard. “I have seen many changes at the company, and I am confident in the direction that has been set by the CEO and the board. I leave knowing that things are in good hands. I am very pleased that Jon Fossel has accepted the role of chairman and know that he will continue to work closely with Tom Watjen and the entire senior management team to ensure a successful future for UnumProvident.”   “Bill has made a tremendous contribution to our company during a very important period, and we will miss his wise counsel, energy and experience,” said Watjen, president and chief executive officer. “We wish him well in all that he does. I look forward to working with Jon Fossel in his new role and with the full board as we continue to build upon the progress we’ve made over the past few years positioning UnumProvident for an era of growth.”   Fossel, 64, joined the UnumProvident board of directors in 2002 and is chairman of the Finance Committee and a member of the Audit Committee. He retired as chairman and chief executive officer in 1996 of the Oppenheimer Funds (approximately $215 billion in assets under management) and continues to serve as a trustee of a number of the

Denver-based company’s funds. Fossel is also a director of Northwestern Corporation, an electricity and natural gas provider.

“I look forward to assuming the role of chairman, and to working with the board and management in continuing the progress made under the leadership of Bill Pollard and Tom Watjen,” said Fossel. “I am confident we have the plans in place that, if executed well, will continue to generate value for our shareholders.”
