Cooperatives have several key characteristics:
1. They are voluntary associations where members democratically control and own the business for their mutual benefit.
2. Membership is open to all without discrimination and members have equal voting rights regardless of investment.
3. Profits are distributed equitably based on use rather than investment, with a limited rate of return on capital.
4. Cooperatives operate for service of members rather than profit, though they may generate surpluses to fund operations.
