Bank of America, Wells Fargo, and JPMorgan Chase have provided more than $18.4 billion in relief to California homeowners. This exceeds by 50 percent the $12 billion promised in a settlement of foreclosure-abuse allegations 20 months ago, according to the monitor, UC Irvine law professor Katherine M. Porter. “I am very, very pleased that these banks delivered such widespread principal reduction so quickly,” Porter said. She pointed out that the California aid included three components: short sales, second liens, and first liens. The California agreement was part of a national settlement announced in February 2012 by Bank of America, Wells, Chase, Citigroup, involving investigations of foreclosure abuses by 49 states and the federal government. The relief is not official until the national mortgage monitor, former North Carolina banking commissioner Joseph A. Smith Jr., has completed auditing of the banks' reports, which should be accomplished by year-end.
