Research Projects

  • The Study of the Accounting Based on Future Events and Their Estimates
    KATO Morihiko; SHIGA Osamu; MURASE Gisuke
    Today, accounting is being revolutionized in Japan. The revolution expands the recongnition area of the accounting. Accountings for contigencies and the impairment of long-lived assets are those examples of this revolution. These accountings recognize events that will occur in the future as accounting events in the current period. We recognize the necessity of analyzing and studying about the theory and practices of such accounting in today. We set following research projects, and studied over 2 years. (1) The study of the conceptual framework to rationalize the accounting practices to introduce the future events into the recognition area (including the study of the individual accounting standards) : We made clear that, in the United States of America, the conceptual framework to expand the recognition area to the future events was built by developing mainly the concept of the future cash flow. We also made clear that the accounting recognizing the future events expanded the area of the judgment concerning the estimates and the forecasts. (2) The research of the necessary condition to recognize future events in the accounting practices : a) We conducted researches what accounting items including forecast factors the companies in America recognized and, if any, what amount they recognized. b) As for the companies in Japan, we conducted the questionnaire about the judgement of future events on 1,359 companies listed on the Tokyo Stock Exchange. (3) The research of the process of the judgment to recognize and measure the future events : We conducted the hearing on some accounting firms and some companies in Japan and America. With those researches, it became clear that the expansion of the accounting practices to recognize future events had been accelerated in America. On the other hand, we recognized that it was difficult to cope with the accounting for future events accompanied by the estimates and the forecasts in Japan, because the accounting system in Japan requires the uniform judgment depending on the law and the administration., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 1998 -1999, Grant-in-Aid for Scientific Research (C), Doshisha University
