Theoretically, owing to tax exemption, nonprofit organizations should open their financial information to the public. But it is scarcely found that nonprofit organizations had full and fair disclosures of their financial statement in practice. This paper studied the two cases of The Red Cross Society of The Republic of China (RCS) and The World Vision Taiwan (WVT) to show the managerial implication of financial disclosures in annual report. Contributors concern efficient use of their donation and have the right to understand the presentation of financial statement for nonprofit organizations. The result of this research suggests that the full disclosure of financial statement in annual report is beneficial to get the public support and reliability. Furthermore, the full disclosure of financial statement can also reinforce the internal function of financial management in nonprofit organizations.
