Jeff O'Neill resigned yesterday as chief executive officer of Priszm Income Fund after taking over the helm of the operator of Canada's KFC restaurants only six months ago. Mr. O'Neill was seen as a key player in turning around the fast-food concern, which also operates Taco Bell and Pizza Hut outlets across the country. "We consider his resignation to be a negative for Priszm and its unitholders," RBC Dominion Securities analyst Walter Spracklin said. Priszm has a 60-per-cent stake in Priszm Limited Partnership, which operates 459 fast-food restaurants. Priszm has faced declining profits as most of its revenue comes from KFC's fried chicken business - a tough sell as more consumers become concerned with obesity and their health. Mr. O'Neill, who previously had been president and chief operating officer since 2005, left for "personal reasons" effective immediately, the fund said. QSR.UN (TSX) fell 20 cents to $2.20.
