Significance and the Materiality Tautology
By Thomas M. Madden
The lack of a bright line test for materiality in securities fraud actions is not new.  It now appears that perhaps the most likely opportunity for a bright line standard came and went with the Supreme Court’s Matrixx decision. Commentators on the consequences to the business of securities fraud class actions have moved on to Halliburton and Amgen. Yet, for those of us concerned with the general understanding of materiality in private 10b-5 actions, Matrixx has reminded us of a terrible fog.
Putting aside for now the narrower discussions of materiality as a class certification issue, materiality as a function of fraud on the market reliance and causality, Matrixx has left us with a fundamental void in defining materiality. The terrible fog is the very definition of materiality.
We need a better standard than the tautological use of significance in place of materiality. Circuit court usage and Supreme Court usage show the inadequacy of significance and it’s ex post/hindsight limitations. We would do better to reemphasis the probability magnitude test language from Basicto give as a more measurable, predictive, ex ante standard.
