Abstract
Using data on shareholder-initiated class action lawsuits in the US, I investigate the corporate scandals of US-listed foreign firms. The shareholders of scandal firms suffer considerable loss in both the short term and the long term. I document that firms domiciled in countries with weak institutions are more likely to be embroiled in corporate scandals, but such a relation can be moderated by the presence of Big 4 auditors. Investors automatically adjust for undiscovered misconduct when valuing the stocks of non-scandal firms. Investors rely on the audit quality to form their expectations about the severity of undiscovered misconduct, and thus impose less negative spillovers on firms with Big 4 auditors, especially when the firms are from countries with weak institutions. Taken together, my results suggest that listing on US exchanges does not fully compensate for weak local institutions; voluntarily bonding to a more stringent audit process has an incremental effect on protecting shareholder interests and enhances the confidence of investors in firms’ financial integrity.
