Credit Union 101
- Unlike banks, credit unions are not-for-profit institutions that exist to serve their members (you), not to make money.
- Credit unions are owned and controlled by their members. Our board of directors is elected by our members - you get to vote.
- Profits made by credit unions are returned to our members in the form of reduced fees, lower rates on loans and higher rates on savings.
- Membership in a credit union is based on something all members have in common - a geographic location or certain occupation, for example. Cornerstone members all live, work, worship or do business in a certain geographic area (see “How to become a member”).
- Because they are owned by community members, most credit unions pride themselves on community outreach and involvement. This is especially true for Cornerstone (see our News & Events to learn more).
