Corporate divestitures: Spin-offs vs. sell-offs

Abstract

We investigate the determinants of the choice between two forms of corporate divestitures—spin-offs versus sell-offs. We hypothesize that the choice is driven by the pre-divestiture market valuation of divesting firms relative to their intrinsic value, the pre-divestiture performance of the assets being divested relative to their full potential, and the prevailing degree of investor optimism or pessimism about the market at the time of divestiture. Our hypotheses generate testable predictions regarding the announcement effects of divestitures and the post-divestiture operating performance of divesting firms. Our empirical findings using a sample of 378 spin-offs and 4192 sell-offs from 1980 to 2011 are as follows. First, firms with lower market valuations relative to their intrinsic value are more likely to spin off their assets. Second, assets which underperform relative to their full potential are more likely to be sold off. Third, spin-offs are more likely during periods of investor optimism. Fourth, spin-offs are associated with more positive announcement effects than sell-offs. Finally, firms which sell off their assets exhibit better post-divesture long-term operating and stock return performance compared to those which spin off their assets.
