FNB United in Asheboro, N.C., announced Friday that its planned name change to CommunityOne Bancorp will take effect Monday.
The $2.1 billion-asset bank said it will also change its stock symbol from "FNBN" to "COB."
Shareholders approved the name change at their annual meeting Wednesday, after the board approved the change in April.
FNB is rebranding in connection with its integration of Bank of Granite in Charlotte, N.C., which it which it bought in 2011. This June, FNB was freed from a regulatory order and has completed its integration of the Bank of Granite.
"Having one name in the market reduces confusion," said Bob Reid, the company's president.
"Along with the change in stock symbol to 'COB,' we now will have one brand to market to all of our stakeholders whether they are our shareholders, customers or the public," CEO Brian Simpson said.
FNB United created a commercial real estate group at one of its banks this January.
