PNC Financial Services Group Inc. said Wednesday it has completed its acquisition of National City Corp., a Cleveland-based bank that dates back to 1845.Pittsburgh-based PNC is the first U.S. bank to use money obtained under the government’s $700 billion bailout program to make an acquisition. PNC and National City announced plans for their $5.6 billion deal on Oct. 24.

The Justice Department has told PNC it will have to sell 61 National City branches in western Pennsylvania to satisfy antitrust concerns.

National City had been Ohio’s largest bank, but it experienced a sharp drop in its stock value and experienced billions of dollars in losses due to its heavy exposure to risky mortgages it had offered to customers.
