A claim was brought on behalf of a class of bank customers who transacted in investments denominated in foreign currency. Plaintiffs alleged that certain related foreign exchange transactions were unauthorized and that class members incurred foreign exchange fees that had not been properly disclosed and claimed damages not only for the fees charged but for the associated lost investment opportunity in respect of those fees. NERA provided an expert report setting out how any damages to the class might be measured and specifically addressing the methodology employed in the plaintiffs’ expert report to estimate the alleged lost investment opportunity. The NERA report set out several reasons why any such compensation for lost investment opportunity would significantly over-compensate members of the class. The case was resolved by way of summary judgment with the court denying any damages for lost investment opportunity.
