GROUP HAS 5.1 PCT OF AMERICAN PHYSICIANS<AMPH.O> A group led by Far Hills, N.J., investors Natalie and Paul Koether told the Securities and Exchange Commission it has acquired 299,523 shares of American Physicians Service Group Inc, or 5.1 pct of the total. The Koether group said it bought the stock for 1.0 mln dlrs for "capital appreciation" and may buy more. The group also said Paul Koether met on June 8 with management representatives for talks that included the company's business, potential acquisitions for the company, possible opportunities to expand the company and the possibility of Koether being named to its board. The group did not say whether the talks resulted in any agreements. As they have done in several SEC filings concerning other companies in which they have had a stake, the Koethers said they reserve the right "to take any actions which they deem appropriate to maximize the value of the shares," but said they have no current plans about taking any action. While they may buy more American Physicians shares, the Koethers also said they may decide to sell some or all of the their stake in the company.
