We have a great experience in the following areas:

Risk Assessment and Damages Exposure

We assist with identifying and assessing potential strengths and weaknesses of an opponent’s damages position, settlement offers, and cost/benefit analyses to help clients effectively manage their case strategies.

Financial Analyses and Damages Theories

We help perform market and competitive analyses, cost determinations, lost-profit analyses, economic studies, statistical analyses, and industry reviews to help our clients develop credible damages theories and models appropriate to a case’s issues. We also assist with the critique of the adversary’s position.


We are experienced in assisting clients and their counsel with damages relating to international commercial disputes and arbitrations, including determining and proving the “loss,” challenging alternatives, and determining foreseeability and mitigation. Some of our senior partners can act as neutral parties in various types of disputes and private arbitrations.
