Signal’s merger with Allied is still being studied.

The government’s antitrust examination of the merger between Allied Corp. and Signal Cos. is expected to be completed soon, according to a Signal executive. Officials from both firms are meeting daily with U.S. authorities, and they have “limited the problems to a very few number,” he said. Nonetheless, Allied delayed for the fourth time the completion of its tender offer to purchase up to 22 million shares of Signal common for $45 per share. The new deadline is July 22.
