Business Notes MINORITY ENTERPRISE

Stephen Yelity, 39, was an accounting manager for Johnson & Johnson, when he decided to start his own computer software firm six years ago. Accurate Information Systems (1988 sales: $10.5 million), based in South Plainfield, N.J., is now the 65th largest black-owned firm in the U.S., according to Black Enterprise magazine.

Like Yelity, a growing number of black executives are leaving large corporations to set up their own companies. During 1988, Black Enterprise reports, sales of the 100 largest black-owned firms grew 10.2%, compared with 7.6% sales growth for FORTUNE 500 firms. Largest by far: TLC Beatrice International Holdings (1988 revenues: $1.96 billion), a multinational food- processing concern acquired by Reginald Lewis in a $985 million leveraged buyout two years ago.
