ADVERSE SELECTION AND THE RIGHTS OFFER PARADOX

We develop an analytical framework to explain firm's choice of equity flotation method and the near disappearance of rights offers by U.S. exchange-listed firms. The choice between uninsured rights, rights with standby underwriting, and firm-commitment underwriting depends on information asymmetries, shareholder characteristics, and direct flotation costs. Underwriter certification and current-shareholder takeup are viewed as substitute mechanisms for minimizing wealth transfers between shareholders and outside investors. Uninsured rights create adverse-selection effects when shareholder takeup is low. Implications for stock-price behavior around issue announcements, shareholder subscription precommitments, and relative issue frequencies are supported by large-sample evidence.
