Briefly

J. & W. Seligman & Co., a New York-based money management firm, said an employee has left the company amid an internal review of possible improper trading that may have diluted mutual fund returns. Seligman plans to reimburse funds harmed by so-called market timing trades, according to a company filing with the Securities and Exchange Commission. Although the inquiry is continuing, Seligman has so far found that any “financial impact” from the trading was minimal.
