Duke Energy and Piedmont Natural Gas

This Statistical Supplement includes results of Piedmont Natural Gas (Piedmont) subsequent to the acquisition on October 3, 2016, and should be read in conjunction with i) Duke Energy and Piedmont's combined Form 10-Q for the nine months ended September 30, 2017, ii) Duke Energy's Annual Report on Form 10-K for the year ended December 31, 2016, iii) Piedmont's Annual Report on Form 10-K for the year ended October 31, 2016, and iv) the transition report filed by Piedmont on Form 10-Q as of December 31, 2016, for the transition period from November 1, 2016, to December 31, 2016.

Segment Change
Due to the Piedmont acquisition and the sale of International Energy in the fourth quarter of 2016, Duke Energy's segment structure has been realigned to include the following segments: Electric Utilities and Infrastructure, Gas Utilities and Infrastructure and Commercial Renewables. The remainder of Duke Energy’s operations is presented as Other. Other now includes the results of National Methanol Company (NMC), previously included in the International Energy segment.
Prior periods have been recast to conform to the current segment structure.

DUKE ENERGY CORPORATION
Non-GAAP Financial Measures
Management evaluates financial performance in part based on non-GAAP financial measures, including adjusted earnings and adjusted diluted EPS.
Adjusted earnings and adjusted diluted EPS represent income from continuing operations attributable to Duke Energy, adjusted for the dollar and per share impact of special items. As discussed below, special items represent certain charges and credits which management believes are not indicative of Duke Energy's ongoing performance. Management believes the presentation of adjusted earnings and adjusted diluted EPS provides useful information to investors, as it provides them with an additional relevant comparison of Duke Energy’s performance across periods. Management uses these non-GAAP financial measures for planning and forecasting and for reporting financial results to the Duke Energy Board of Directors, employees, stockholders, analysts and investors. Adjusted diluted EPS is also used as a basis for employee incentive bonuses. The most directly comparable GAAP measures for adjusted earnings and adjusted diluted EPS are Net Income Attributable to Duke Energy Corporation (GAAP Reported Earnings) and Diluted EPS Attributable to Duke Energy Corporation common stockholders (GAAP Reported EPS), respectively.
Special items included in the periods presented include the following items which management believes do not reflect ongoing costs:
Costs to Achieve Mergers represent charges that result from strategic acquisitions.
Cost Savings Initiatives represent severance charges related to company-wide initiatives, excluding merger integration, to standardize processes and systems, leverage technology and workforce optimization.
Commercial Renewables Impairments represents other-than-temporary and asset impairments.
Florida Settlement represents an impairment charge related to the Levy nuclear project based on a settlement agreement approved by regulators.
Adjusted earnings also include operating results of the International Disposal Group, which have been classified as discontinued operations. Management believes inclusion of the operating results of the Disposal Group within adjusted earnings and adjusted diluted EPS results in a better reflection of Duke Energy's financial performance during the period.
Due to the forward-looking nature of any forecasted adjusted earnings guidance, information to reconcile this non-GAAP financial measure to the most directly comparable GAAP financial measure is not available at this time, as management is unable to project all special items for future periods (such as legal settlements, the impact of regulatory orders, or asset impairments).
Management evaluates segment performance based on segment income and other net expense. Segment income is defined as income from continuing operations attributable to Duke Energy. Segment income includes intercompany revenues and expenses that are eliminated in the Consolidated Financial Statements. Management also uses adjusted segment income as a measure of historical and anticipated future segment performance. Adjusted segment income is a non-GAAP financial measure, as it is based upon segment income adjusted for special items, which are discussed above. Management believes the presentation of adjusted segment income provides useful information to investors, as it provides them with an additional relevant comparison of a segment’s performance across periods. The most directly comparable GAAP measure for adjusted segment income or adjusted other net expense is segment income and other net expense.
Due to the forward-looking nature of any forecasted adjusted segment income or adjusted other net expense and any related growth rates for future periods, information to reconcile these non-GAAP financial measures to the most directly comparable GAAP financial measures is not available at this time, as the company is unable to forecast all special items, as discussed above.
Duke Energy’s adjusted earnings, adjusted diluted EPS, and adjusted segment income may not be comparable to similarly titled measures of another company because other companies may not calculate the measures in the same manner.
