Abstract

The purpose of this paper is to analyze the stock market performances CAR of reorganized firms and study the disclosure effect of completion of reorganization to examine whether there exists significant economic merit for the institutionalized continuation of unprofitable firms. The main results of this paper can be summarized as follows. First, the average stock market performances for +12 months after the completion of reorganization compared to those for -6 months before the proposal of reorganization show consistently negative returns. Second, to see whether there exist significant differences between the stock market performances of reorganized firms and those of normal firms with similar characteristics, CAR's measured from -6 months before the proposal of reorganization to +12 months after the completion of reorganization are statistically tested, which results in significantly negative values starting +5 months after the completion of reorganization. Finally, to see the disclosure effect of the news of completion of reorganization, daily CAR's are measured and tested, which shows positive values only for -20 days and -19 days before the disclosure, and shows negative values for the whole periods up to +20 days after the disclosure. The results of the paper imply consistently that the reorganized firms have no better performances compared to the similar normal firms, and the performances do not improve even after the completion of reorganization, which casts serious doubts upon the current forms of the institutionalized continuation of unprofitable firms.
