ProAssurance Investor Briefing | May 2022 38 Forward Looking Statements Non-GAAP Measures This presentation contains Forward Looking Statements and other information designed to convey our projections and expectations regarding future results. There are a number of factors which could cause our actual results to vary materially from those projected in this presentation. The principal risk factors that may cause these differences are described in various documents we file with the Securities and Exchange Commission, such as our Current Reports on Form 8-K, and our regular reports on Forms 10-Q and 10-K, particularly in “Item 1A, Risk Factors.” Please review this presentation in conjunction with a thorough reading and understanding of these risk factors. This presentation contains Non-GAAP measures, and we may reference Non-GAAP measures in our remarks and discussions with investors. The primary Non-GAAP measure we reference is Non-GAAP operating income, a Non-GAAP financial measure that is widely used to evaluate performance within the insurance sector. In calculating Non-GAAP operating income, we have excluded the after-tax effects of net realized investment gains or losses and guaranty fund assessments or recoupments that do not reflect normal operating results. We believe Non-GAAP operating income presents a useful view of the performance of our insurance operations, but should be considered in conjunction with net income computed in accordance with GAAP. A reconciliation of these measures to GAAP measures is available in our regular reports on Forms 10-Q and 10-K and in our latest quarterly news release, all of which are available in the Investor Relations section of our website, Investor.ProAssurance.com.
