Like any financial institution, credit unions have the financial resources. In 1908. the spread of credit unions has reached the United States. In 1935 President Roosevelt signed the state Charter on credit unions, which became a law. The relationship of shareholders with credit union are not client-based, they are co-operative, based on different principles and standards, in particular, on the principles of the law of obligations. Taking a decision to join a credit union, citizens create an organization through which they participate in the shared savings by mutual crediting and joint (collective) use of personal savings. In the case of default the shareholder - individual will respond with its property and, in addition, is jointly and severally liable with the credit union's commitments. The value of credit unions is not limited to the role of the economic agent - they are an important element of the social structure and a factor of social stability and progress. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. On the consumer credit market in the U.S. credit unions are on the third place after the commercial banks and finance companies and are ahead of savings institutions, not taking into account the loans on real estate.
