PNC Bank acquired the deposits and some assets of Dwelling House Savings and Loan Association on Friday, after the latter became the 73rd U.S. bank to fail this year.

The Federal Deposit Insurance Corp. said that Pittsburgh, Pa.-based Dwelling House was closed by the Office of Thrift Supervision. The FDIC then entered into a purchase and assumption agreement with PNC to acquire approximately $13.8 million in deposits from Dwelling House, as well as $3 million in the failed bank's assets.

The FDIC estimates that the failure, the 98th since the beginning of 2008, will cost the federal deposit insurance fund $6.8 million.
