The Company’s management uses core non-GAAP financial metrics (“Core”) in their analysis of the Company’s performance to identify core revenues and expenses in a period that directly drive operating net income in that period. These Core measures typically adjust GAAP performance measures to exclude the effects of the amortization of intangibles and include the tax benefits associated with revenue items that are tax-exempt, as well as adjust income available to common shareholders for certain significant activities or transactions that in management’s opinion can distort period-to-period comparisons of the Company’s performance. Reference is made to “Non-GAAP Financial Measures” and “Caution About Forward Looking Statements” in the earnings release which also apply to certain disclosures in this PowerPoint presentation.
