PNC Financial Services Group Inc. (PNC) said Wednesday that several charges tied to faulty mortgages would reduce fourth-quarter earnings, illustrating the housing-crisis damage continues for banks despite a settlement with regulators earlier this week.

PNC had been warning since last summer that repurchase demands by Fannie and Freddie had increased. In the second quarter it increased its provision for such loans to $438 million from $21 million in the year-earlier quarter.
