This expertise is critical for interpreting complex financial data and assessing the economic impact of legal disputes in areas such as antitrust, securities fraud, and intellectual property. Our experience across a broad range of industries—including technology, telecommunications, healthcare, automotive, finance, energy, construction, sport, and real estate—allows us to provide context-driven insights tailored to the matter in question.
Quantitative Skills
Our teams include members with advanced skills in accounting, economics, financial valuation, damages and quantum, as well as data analysis, including proficiency in econometric modeling, statistical analysis, and handling of large datasets. These quantitative skills are essential for determining economic damages and analyzing transaction records, pricing trends, and economic impact, often using software such as Stata, R, SAS, or Python. Our ability to present complex economic models and derive clear, actionable insights from data is critical in proving or disproving claims in high-stakes litigation. We ensure our findings are accurate, defensible, and backed by rigorous quantitative analysis.

Our experts’ ability to clearly communicate complex economic concepts in a way that judges, tribunals, juries, and non-expert stakeholders can understand is key to driving successful outcomes for our clients. We excel not only in preparing thorough, well-documented reports, but also in presenting and defending our findings confidently under cross-examination. Our experts leverage decades of experience, clear and concise communication skills, and courtroom presence with quantitative and industry expertise to deliver critical insights and compelling, credible testimony that influences legal outcomes.
