Intellectual capital is the result of mental processes that form a set of intangible objects that can be used in economic activity and bring income to its owner (organization), covering the competencies of its people (human capital), the value relating to its relationships (relational capital), and everything that is left when the employees go home (structural capital), of which intellectual property (IP) is but one component. It is the sum of everything everybody in a company knows that gives it a competitive edge. The term is used in academia in an attempt to account for the value of intangible assets not listed explicitly on a company's balance sheets. On a national level, intellectual capital refers to national intangible capital (NIC).
