Forward-looking statements are based on management’s current expectations and assumptions about future events. These statements are only predictions and are not guarantees of future performance. Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements, if the underlying assumptions prove to be incorrect or as the result of risks, uncertainties, and other factors, including the impact of the COVID-19 pandemic on the business and operations of the Company and our policyholders.

Non‐ GAAP Financial Measures Within this investor presentation we may present certain financial measures, including adjusted return on equity and adjusted net income, which are non‐ GAAP financial measures as defined in Regulation G pursuant to Section 401 of the Sarbanes‐ Oxley Act of 2002. If presented, a reconciliation of such non‐ GAAP financial measures to our most directly comparable GAAP financial measures will be included in the attached appendix. Management believes that these non‐ GAAP financial measures are important to the Company's investors, analysts and other interested parties who benefit from having an objective and consistent basis for comparison with other companies within our industry. Management further believes that these measures are more relevant than comparable GAAP financial measures in evaluating our financial performance. These measures should not be viewed as a substitute for those determined in accordance with GAAP. Reconciliation of these measures to their most comparable GAAP financial measures are included in the appendix to this presentation. They are also included in our most recent earnings release available in the “Investor Relations” section of our website at www.trean.com.
