LAURENTIAN GROUP SEES HIGHER SHARE NET <Laurentian Group Corp> said it expects 1987 earnings per share will show about the same proportionate increase as in 1986. Last year, the company had 25.7 mln dlrs operating profit, or 76 cts per share, up from 11.1 mln dlrs, or 59 cts per share, in 1985. Shares outstanding increased to 39 mln from 27.8 mln. The American holding company, Laurentian Capital Corp, will show a substantial improvement this year, chairman Claude Castonguay said before the annual meeting. Laurentian Capital Corp, which recently acquired two small U.S. life insurance companies, had 1986 profit of 1.1 mln U.S. dlrs, or eight cts per share, compared to seven mln U.S. dlrs, or 68 cts per share. Castonguay said Laurentian Group Corp, the parent firm, plans to fill out its national financial services distribution system and make further acquisitions if the right opportunity occurs. The company also may expand this year in continental Europe, in conjunction with La Victoire, a French insurance company, he said.
