A group bought 13.3% of Informatics General.

The group, consisting of Maxxam Properties and TSG Park Avenue Holdings, said in an SEC filing that it purchased its 663,000 shares in the Woodland Hills company for investment purposes. But group representatives have indicated to Informatics that they “would be willing to discuss with management the possible arrangement to acquire” the company. Meanwhile, the computer software and services company, which has rebuffed takeover efforts by Sterling Software, reported that first-quarter earnings declined to $68,000 from $689,000 for the same period in 1984. Revenues rose 22% to $49.9 million. An Informatics spokeswoman declined to elaborate on either development.
