M&F Bancorp of North Carolina, one of the nation’s oldest black-owned banks, is launching an effort to revamp its business model to counter the challenges MDIs are facing. With about 60% of its customers over 60 years old, M&F is rebranding and working to reach new customers in order to serve a wider community base. "I just don't think we're going to have more African-American banks open," Sills said. "I think it is incumbent on the ones that are remaining to make sure they're relevant and they're trying to reach out to as many groups or market segments in their various communities to make sure their bank is around for the next 15 or 20 years. I just don't think you can rely totally on one segment of the community."
