In seasoned equity rights offers, the standby underwriting contract re
sembles the sale of a put option. In the rights offering period, under
writers reduce their exposure to the standby underwriting by purchasin
g rights hedged with short sale of the common stock. Consistent with E
ckbo and Masulis (1992), offers with large rights sell-offs during the
offering period experience significant price decline. The offering pe
riod price decline and the nature of constraints confronting underwrit
ers may partially explain the preference for general public offers.
