Damages experts are ever-more frequently being challenged on the reliability of their opinion evidence under the Daubert standard. One of the most commonly cited reasons for excluding experts is that their analyses were not supported by sufficient facts or data. This session will use detailed examples from case law to identify specific risk-areas that valuation professionals need to be aware of when working on cases with data issues, and the types of procedures they can use to protect themselves from being excluded as an expert witness at trial. This presentation will provide practical, hands-on insights directly relevant to both US and Canadian practitioners. The presentation will be delivered in a high-energy and interactive manner that will aim to capture the interest of the audience.
