We empirically analyze the information hypothesis that the separation of a "rm's divisions into independently traded units through a spin-o! enhances value because it mitigates information asymmetry about the "rm. Consistent with this hypothesis, we "nd that "rms that engage in spin-o!s have higher levels of information asymmetry compared to their industry and size matched counterparts and the information problems decrease signi"cantly after the spin-o!. The gains around spin-o!s are positively related to the degree of information asymmetry, and this relation is more pronounced for "rms with fewer negative synergies between divisions. Finally, "rms with higher growth opportunities and "rms in need of external capital show a higher propensity to engage in spin-o!s. They also raise more capital following a spin-o!, which is consistent with the view that * Corresponding author. Tel.: #1-504-280-6488; fax: #1-504-280-6397.E-mail address: skrishn1@uno.edu (S.
