In our paper, Seasoned Equity Offerings, Corporate Governance, and Investments, forthcoming in the Review of Finance, we assess how the strength of governance affects investor confidence about management’s intended uses of the proceeds from SEOs. Our primary tests are conducted using difference-in-differences approaches using the staggered enactments of business combination statutes (BCS) as an exogenous shock weakening external pressure for good governance from the market for corporate control.
These tests are supplemented by two additional analyses, one relying on shareholder-value-reducing acquisitions as an ex post proxy for weak governance; the other relying on top management’s firm-related wealth sensitivity to shareholder value as a proxy for the strength of internal governance. These empirical analyses cover different sample periods spanning 1982 through 2006. Investor reaction to SEOs is positively and significantly related to the strength of governance regardless of which empirical strategy we use and which time period we examine.
The economic magnitudes of governance impacts are surprisingly large, explaining much of the negative stock price reactions to the announcement of SEOs. Absent secondary offerings, investors’ main concern with SEOs is whether management will use the proceeds productively or wastefully. Good governance enhances investor confidence, helping firms raise external equity at lower costs.
