In the accountability model, which is distinctly different from the information supplier model, the accountant's role is to provide information on the working of the accounter, who is accountable to the accountee. The terms accounter and accountee were coined by Ijiri. The accounter is the agent of the accountee, who is the principal. If we reflect on the basic concepts of the law of contract, the accountee may want information even if it is uncomfortable for the accounter. The accountant should function as a scorekeeper for the accountee. The accounter, on the other hand, would want to reveal as little information as possible that may reflect poorly on him/her. Control theory would show that such consequent tension can be ameliorated by trust and could be optimally balanced if some privacy and autonomy is given to the accounter, but not such total autonomy that the system may spin out of control due to what is known as 'opportunistic behaviour' on the part of the accounter
