EWS Long Term Growth Framework

Non-GAAP Disclosure Statement This presentation contains certain non-GAAP financial measures, including adjusted EPS and adjusted EBITDA, which reflect adjustments for certain items that affect the comparability of our underlying operational performance. Adjusted EPS is defined as net income adjusted for acquisition-related amortization expense, legal expenses related to the 2017 cybersecurity incident, fair value adjustment and gain on sale of equity investments, foreign currency impact of certain intercompany loans, acquisition-related costs other than acquisition amortization, income tax effect of stock awards recognized upon vesting or settlement, Argentina highly inflationary foreign currency adjustment, realignment of internal resources and other costs, gain on settlement of Canada pension plan, and adjustments to deferred tax balances. Adjusted EBITDA is defined as consolidated net income attributable to Equifax plus net interest expense, income taxes, depreciation and amortization, and also excludes certain one-time items. Local currency is calculated by conforming the current period results to the comparable prior period exchange rates. Local currency can be presented for numerous GAAP measures, but is most commonly used by management to analyze operating revenue without the impact of changes in foreign currency exchange rates. Organic revenue growth is defined as revenue growth, adjusted to reflect an increase in prior year Equifax revenue from the revenue of acquired companies in the prior year period. This adjustment is made for 12 months following the acquisition. Organic non-mortgage revenue growth is defined as revenue growth within our non-mortgage verticals adjusted to reflect an increase in prior year Equifax revenue from the revenue of acquired companies in the prior year period. This adjustment is made for 12 months following the acquisition. These non-GAAP measures are detailed in reconciliation tables which are included with our earnings release and are also posted at www.equifax.com under "Investor Relations/Financial Results/Non-GAAP Financial Measures."
