JPMorgan Chase trumpeted some impressive news on Jan. 14, 2011. It had earned a record $17.4 billion in quarterly profits in fiscal year 2010, a 47 percent jump from the previous quarter. Three days later, the bank quietly released a less flattering statement. Its mortgage-servicing division, the third largest in the country, had overcharged some 4,000 active-duty troops on their mortgages and improperly foreclosed on 14 of them, violating a law called the Servicemembers Civil Relief Act. This story broke because of embarrassing litigation. A Marine F-18 fighter pilot, Capt. Jonathan Rowles, who had been faithfully paying his mortgage, was marked delinquent. He and his wife hired a lawyer and spent two years fighting to get JPMorgan Chase to relent.
