The demand to hold cash of managers may cause the earnings manipulation. Since managers want cash to satisfy them, they may create the financial statement to increase cash balance for their own interests. Moreover, the managers’ compensations are partly tied to company’s performance, while the most obvious and easiest way to evaluate company’s effectiveness is through financial report. Thus, managers might have incentive to create statement to show consistently good performance. Not only shareholders are affected from this conflict of interest problem but outside investors also are influenced. Financial statements give company’s information for evaluating any financial activities such as debt approval or securities trading. The manipulated financial report will not reflect company’s true economic value that will lead to unreliable valuation and, in turn, wrong investment decision.
