Institutional dual holdings and expected crash risk: Evidence from mergers between lenders and equity holders

Exploiting mergers between lenders and shareholders of the same firm as an exogenous shock to shareholder–creditor conflicts, we examine the causal effect of these conflicts on firms' ex ante expected stock price crash risk evident in the options implied volatility smirk. The decrease in conflicts of interest between lenders and shareholders induces dual holders to encourage the disclosure of more information to alleviate costly information asymmetry with other investors and better execute their oversight role in constraining managers' bad news suppression. Consistent with expectations, we find that a firm's ex ante expected crash risk declines after a shareholder–creditor merger. We also report strong, robust evidence that the negative impact of mergers on firms' expected crash risk increases when institutional investors or lenders have a greater stake in the treatment firms or when shareholder–creditor conflicts are apt to be exacerbated. Additionally, we document that firms issue management earnings forecasts (especially bad news forecasts) more frequently after these mergers. Finally, we find that expected crash risk decreases more after mergers in firms suffering worse information asymmetry and with weak monitoring mechanisms. Our evidence suggests that option market participants value the dual holder's role in deterring managers' bad news hoarding.
