From the discussions in section 2 and 3 we can conclude that both researchers and practitioners are aware of the importance of IC for value creation. Thus, IC is a relevant concept to pay attention to. In order to manage and control IC within companies identifying, measuring and reporting internally on IC is required. Knowing how to identify, measure and report on IC is also needed for being able to give an insight into the value creation capacities of IC to the external stakeholders. Below we discuss the building blocks of an IC reporting model. We start with discussing the main assumptions which underlie such a model. Then, we develop the building blocks of the content of an IC report. We deal in particular with the requirements an external IC report should meet, and with its consequences for the characteristics of such an external report.
