WASHINGTON ( TheStreet) -- Six community banks failed Friday, bringing the 2010 tally of failed U.S. banking institutions to 15. Friday's failures are expected to cost the Federal Deposit Insurance Corp.'s insurance fund a total of $1.9 billion. All six failed institutions had been previously assigned E-minus (Very Weak) financial strength ratings by TheStreet.com Ratings, and all were included in TheStreet.com's list of undercapitalized banks and thrifts. The Office of the Comptroller of the Currency shut down First National Bank of Georgia of Carrollton, Ga., a subsidiary of WGNB ( WGNB.PK). The FDIC was appointed receiver and sold the failed bank's $758 million in deposits for a 1.25% premium to Community & Southern Bank, also of Carrollton, Ga. Community & Southern also acquired the failed bank's $833 million in assets, with the FDIC agreeing to share in losses on $607 million and estimating that the cost to its insurance fund would be $260.4 million.
