From the stimulus, it appears that the intangible value of C2G as a company in the form of goodwill, brand value, reputation and so on is tied to the personality and lifestyle of Charles, as he is very popular with the younger generation. It appears that Charles is responsible for creating some of the innovative flavours, which have made the company so successful.
The difficulties of this for C2G's intangible assets is that it can be hard to objectively value the contribution of Charles's personality and lifestyle as well as his innovative attitude while the company is still operating. This can have a true positive impact on the brand value and effectively brand loyalty of customers, but the value can either be estimated or proven when the company is sold for a price above its tangible assets. Until then, the intangible assets can only be estimated if at all. Perhaps C2G can research the value of family branding more easily measured in terms of research on brand recognition, but the effects on personality factors can be very difficult to accurately measure.
Moreover, the success of the brand (and hence intangible asset) could also be down to very good promotion or targeting. Other companies without personality cults also have successful brands.
Innovation as a contributor to C2G's tangible assets can also be very difficult to measure due to the fact that one factor can be difficult to isolate in terms of its contribution to the intangibles.
Moreover inconsistencies of reporting systems between companies exist. Current financial statements provide very little information about these assets and there is not a standardized / unified method of valuation of the intangible assets. Therefore, the Financial Manager is unlikely to insert a figure that is no more than estimated.
