Trilogy said its settlement has been approved.

Under the agreement in the class-action suit filed by shareholders in 1984, a total of $8 million in cash and stock will be paid to persons who purchased shares of Trilogy between Nov. 9, 1983, and Aug. 14, 1984. The settlement, approved by a federal court in San Jose, resulted in a one-time expense of about $5 million to the company, which was charged to its fiscal 1985 fourth quarter.
