Credit unions are not-for-profit financial cooperatives serving groups of members who have something in common such as employment at a company, membership in an association, or residence in a particular geographic area. A credit union that may serve anyone who lives or works within a particular geographic area is called a community credit union. A credit union that serves groups of employees or associations is typically called a SEG-based (for select employee group) or a sponsor-based credit union. BCU is SEG-based. More than 139.3 million U.S. consumers are member-owners and receive all or part of their financial services from the nation's 4,604 federally insured credit unions.
