Measuring damages from shareholders’ trading records over multiple corrective disclosures

An Australian client engaged Brattle to quantify damages caused by a set of alleged omissions and false and misleading representations that the company revealed over a series of corrective disclosures. Our analysis quantified the per-share damages attributed to the alleged misconduct, as well as the dollar amount of damages for individual registered shareholders. We applied the LIFO/FIFO framework to calculate the damages for shareholders using actual trading records. Our analysis also examined shareholders’ trading patterns – using the trading records of the registered shareholders – and applied the assumption of the trading pattern to a generalized trading model to quantify the open-class damages. Ultimately, our client settled the case favorably.
