General Motors Acceptance Corp. may have difficulty increasing its earnings in 2005 due to rising interest rates and health-care costs. Expanding profits in its finance unit is needed to cover declines in GM's auto units.
GM's Chairman and CEO Rick Wagoner told The Wall Street Journal that these costs will be “headwinds” for the automaker. He added that GM's Japanese rivals have benefited from Japan's yen being undervalued against the U.S. dollar.
