It's not quite the average $8,000 windfall they got last year, butCorp.'s 72,700 U.S. hourly workers will receive an average profit-sharing check of $3,200 Feb. 16, based on the company's $2 billion profit for 1995. And Chrysler's 27,000 salaried troops stand to get even more, although a company spokesman declined to disclose the average white-collar payment. Meanwhile, the folks from Auburn Hills are positioned for a strong start to '96 because they are planning to build 20% more vehicles than they did in the first three months of '95. Motor Co.'s profit sharing is expected to be between $1,200 and $1,500, or about one-third last year's average of $4,000. Corp. will be in the same range as Ford. But Wall Street's projections for GM and Ford are cooling considerably. Salomon Brothers' Jack Kirnan dropped his '96 estimate for GM from $7.25 to $5 per share, and downgraded it from "buy" to "hold." Ford still has a bumpy road through the first half, but Chairman Alex Trotman tells analysts profits will recover robustly in the second half after the '97 F-series pickup, Ford Escort and Mercury Tracer are in full production.
