This time, the bank is being more careful about how to get it. On Thursday the bank sketched out plans for regaining some of the ground it lost in home lending. That's a change from the strategy of the last few years, when it concentrated on shedding parts of its mortgage business. Under the new approach the bank is targeting people who are already customers. It also wants to focus on making loans directly to borrowers, rather than buying mortgages from other lenders. ___ Legal expenses drag down Citigroup 4Q earnings Citigroup's fourth quarter earnings fell short of Wall Street's expectations as the bank's legal expenses rose and it released less money from its loan-loss reserves. The bank, based in New York, said a big chunk of the legal expenses came from a settlement reached last week over illegal foreclosure practices in the aftermath of the housing bust. It was Citigroup's first quarter under the leadership of CEO Michael Corbat, who took the helm after former CEO Vikram Pandit resigned abruptly in October. ___ By The Associated Press(equals) The Dow Jones industrial average rose to 84.79 points higher at 13,596.02.
