The investigation on the application of funds can be such that investigates whether the regulations of common public interest of a business or an association have been met. However, a business that manages to earn profit can therefore still be called ‘charitable’ as long as it fulfills all its tax duties or evades them according to the law. This investigation can also refer to the usage of financial capital, which are contractually stated with investors or shareholders. In the case of arising doubts, the investor can appoint an auditor to examine the usage of the funds on correctness by checking the financial documents. Finally the auditor assesses whether the money has been used legally and contractually in the correct way.
