Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. Credit unions are competitors of savings institutions, adding interest on deposits of members. This applies to the shares, as well as to additional funds transferred to the account in the credit union. Unlike banks, in order to use the services of a credit union, you have to become its member, having written an application and having paid thus shares and membership fee. Today, the World Council of Credit Unions is represented as members four regional confederations and twelve national associations.
