By BridgeNews and Jill Jusko Dana Corp. posted an operating net income of 1 cent a share in the fourth quarter, above analysts' estimates of breakeven. The company, however, lost 57 cents a share in the quarter, compared with breakeven a year ago. The company says its fourth-quarter losses were the result of several factors, including irregular and reduced production schedules for light trucks and sport-utility vehicles, further deterioration of the U.S. heavy-truck market, continued aftermarket softness, and weakness of the euro. Dana Corp.'s fourth-quarter sales fell to $2.7 billion from $3.2 billion in the year-ago period. The company expects earnings for the first quarter to be about the same as its fourth-quarter results.
