Knoll already owns 796,413 shares or 9.9 pct of American Savings. American Savings said the purchase will resolve a previously-announced disagreement between American Savings and the Federal Home Loan Bank of Atlanta on the replacement of the capital American Savings used to repurchase common shares in January 1985 from former chairman Marvin L. Warner. It said completion of the transaction would give Knoll 15 pct ownership in American Savings. American Savings said Knoll also had talks with chairman of the executive committee Shepard Broad and chairman Morris Broad on the purchase of their American Savings shares as well at 20 dlrs each but no agreement was reached. American Savings said The company said Knoll's offer to buy the new shares is not conditioned on other purchase of common stock from any person or entity. It said its previously-announced engagement of Salomon Inc <SB> to evaluate alternatives to enhance shareholder values, including the possible sale of American Savings, is still being actively pursued.
