Battle Creek (Mich.) Police & Fire Retirement System put Rorer Asset on watch for performance of a $17 million active domestic large-cap core equity portfolio, said Stanley Chubinski, city treasurer. The $98 million plan does not have a policy for the length of time a manager can be on watch, Mr. Chubinski said. The manager will be reviewed Feb. 25, when trustees conduct a full quarterly performance review. Smith Barney is assisting. Rorer officials would not comment.
