Our Experience 

Class Certification

FRCP Rule 23 requires (1) showing that common questions predominate the class members’ claims and (2) showing that these questions can be addressed using a common method of proof without individualized inquiry. Catalyst excels at conducting the complex economic, financial, and statistical causal analysis required to address questions arising under FRCP Rule 23

Class Action Damages

Class action damage calculations require careful analysis of both the fact and quantum of harm. To be reliable, the damages analysis should identify which class members are potentially harmed and quantify the amount of harm using data available to the class. However, in some cases, individualized inquiry is necessary to determine damages. Catalyst specializes in conducting the analyses required to calculate reliable class action damages and to evaluate proposed damages.

Securities Class Actions

Catalyst provides expert witness support and consulting in all phases of securities class actions, including Rule 10b-5, Section 11 and 12 and ERISA matters. We have worked on a range of securities fraud cases involving stocks and bonds traded on the NASDAQ and NYSE, dual listed ADRs, and OTC traded stocks, bonds and derivatives. Our securities litigation experts excel in translating the results of these complex economic analyses into easily understood testimony.
