Piling On? An Empirical Study Of Parallel Derivative Suits, Stephen J. Choi, Jessica Erickson, Adam C. Pritchard Nov 2017

Piling On? An Empirical Study Of Parallel Derivative Suits, Stephen J. Choi, Jessica Erickson, Adam C. Pritchard

Articles

Using a sample of all companies named as defendants in securities class actions between July 1, 2005 and December 31, 2008, we study parallel suits relying on state corporate law arising out of the same allegations as the securities class actions. We test several ways that parallel suits may add value to a securities class action. Most parallel suits target cases involving obvious indicia of wrongdoing. Moreover, we find that although a modest percentage of parallel suits are filed first, over 80 percent are filed after a securities class action (termed “follow-on” parallel suits). We find that parallel suits and, …


Carrot Or Stick? The Shift From Voluntary To Mandatory Disclosure Of Risk Factors, Karen K. Nelson, Adam C. Pritchard Jun 2016

Carrot Or Stick? The Shift From Voluntary To Mandatory Disclosure Of Risk Factors, Karen K. Nelson, Adam C. Pritchard

Articles

This study investigates risk factor disclosures, examining both the voluntary, incentive-based disclosure regime provided by the safe harbor provision of the Private Securities Litigation Reform Act as well as the SEC's subsequent mandate of these disclosures. Firms subject to greater litigation risk disclose more risk factors, update the language more from year to year, and use more readable language than firms with lower litigation risk. These differences in the quality of disclosure are pronounced in the voluntary disclosure regime, but converge following the SEC mandate as low-risk firms improved the quality of their risk factor disclosures. Consistent with these findings, …


Sec Investigations And Securities Class Actions: An Empirical Comparison, Stephen J. Choi, Adam C. Pritchard Mar 2016

Sec Investigations And Securities Class Actions: An Empirical Comparison, Stephen J. Choi, Adam C. Pritchard

Articles

Using actions with both an SEC investigation and a class action as our baseline, we compare the targeting of SEC-only investigations with class-action-only lawsuits. Looking at measures of information asymmetry, we find that investors in the market perceive greater information asymmetry following the public announcement of the underlying violation for class-action-only lawsuits compared with SEC-only investigations. Turning to sanctions, we find that the incidence of top officer resignation is greater for class-action-only lawsuits relative to SEC-only investigations. Our findings are consistent with the private enforcement targeting disclosure violations at least as precisely as (if not more so than) SEC enforcement.


Stoneridge Investment Partners V. Scientific-Atlanta: The Political Economy Of Securities Class Action Reform, Adam C. Pritchard Jan 2008

Stoneridge Investment Partners V. Scientific-Atlanta: The Political Economy Of Securities Class Action Reform, Adam C. Pritchard

Articles

I begin in Part II by explaining the wrong turn that the Court took in Basic. The Basic Court misunderstood the function of the reliance element and its relation to the question of damages. As a result, the securities class action regime established in Basic threatens draconian sanctions with limited deterrent benefit. Part III then summarizes the cases leading up to Stoneridge and analyzes the Court's reasoning in that case. In Stoneridge, like the decisions interpreting the reliance requirement of Rule 10b-5 that came before it, the Court emphasized policy implications. Sometimes policy implications are invoked to broaden the reach …


Should Congress Repeal Securities Class Action Reform?, Adam C. Pritchard Jan 2003

Should Congress Repeal Securities Class Action Reform?, Adam C. Pritchard

Other Publications

The Private Securities Litigation Reform Act of 1995 was designed to curtail class action lawsuits by the plaintiffs’ bar. In particular, the high-technology industry, accountants, and investment bankers thought that they had been unjustly victimized by class action lawsuits based on little more than declines in a company’s stock price. Prior to 1995, the plaintiffs’ bar had free rein to use the discovery process to troll for evidence to support its claims. Moreover, the high costs of litigation were a powerful weapon with which to coerce companies to settle claims. The plaintiffs’ bar and its allies in Congress have called …
