The Company uses non-GAAP financial measures to evaluate financial performance, analyze underlying business trends and establishoperational goals and forecasts that are used when allocating resources. The Company believes these non-GAAP financial measures permit investors to betterunderstand changes in underlying operating performance over comparative periods by providing financial results that are unaffected by cyclical variances thatcan be driven by items such as investment activity or purchase accounting adjustments. While the Company believes these measures are useful to investorswhen evaluating performance, they are not prepared and presented in accordance with GAAP, and therefore should be considered supplemental in nature. TheCompany’s non-GAAP financial measures should not be considered in isolation or as a substitute for other financial performance measures presented inaccordance with GAAP. These non-GAAP financial measures may have material limitations including, but not limited to, the exclusion of certain costs without acorresponding reduction of net income for the income generated by the assets to which the excluded costs are related. In addition, these non-GAAP financialmeasures may differ from similarly titled measures presented by other companies.

A reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measure can be found in the Appendix as well asCompany’s latest Form 8-K, filed with the SEC on November 25, 2019.
