Firms often secure financing through sell-off to concentrate on their major business, hence improving operating performance or enhancing financial structure. This research investigates Taiwanese listed companies which have had sell-off experiences during 1991-2000. Pertinent financial ratios of the two-year period before and after the sell-off were used for empirical analysis. The results have shown that the dollar amount from selling assets is relatively small compared with total asset base. The sell-off has no effect on operating performance, while on the other hand, it has significant influence on the ratio of total assets in terms of total liability, cash and marketable securities, and land and properties.
