The companies, determined to identify its intellectual material, already know that they can find it in one or more than these three places: people, structures and customers, that is, human, capital capital structural and capital of the customer, being: Human capital – the qualification, the abilities and knowledge and the capacity of generation of ideas and innovation of the work force; Structural capital – the part that belongs to the company, that is, the data bases, the procedure manuals; it is everything what the employee cannot lead when returns for house in the end of the expedient; Capital of the customer – it is the value of the relationships of a company with the people with which it makes businesses, that is, the value of the surmounting of the company, of the relationship with the customers, loyalty to the mark of the company and the capacity of the company to know the necessities of its customers and to anticipate solutions for its future problems. In marketing terms, it is here, in the relationships with the customers, who the intellectual capital if transforms into financial return. With this, it is verified that the intellectual capital is not created from distinct parts of human, structural capital or of customer, but of the interchange and/or association between them.
