First Credit Union was savings unprofitable institution, or rather credit cooperative, providing services to its members. Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the credit union. 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. Shareholders in corporate organizations are basic credit unions, besides the same union can be a shareholder of several corporate organizations.
