Earnings at the company's regulated utilities were slightly lower for the quarter. U.S. Franchised Electric and Gas experienced higher earnings resulting from the company's power plant investments and modernization program but, as expected, this was offset by less favorable weather and higher operation and maintenance costs. Strong results from Duke Energy International and reduced corporate costs contributed to the increase in adjusted diluted EPS.

"We built a solid foundation in the first quarter for another successful year," said James E. Rogers, chairman, president and chief executive officer. "A continued focus on operational excellence as we execute our business plan will help us achieve our 2011 earnings guidance range of $1.35 to $1.40 per share.

"Additionally, we made initial regulatory filings related to the merger with Progress Energy and continue to target a closing date by the end of 2011," he said.

Mark-to-market impacts of economic hedges in the Commercial Power segment and special items affecting Duke Energy's adjusted diluted EPS for the quarters include:

Reconciliation of reported to adjusted diluted EPS for the quarters:

BUSINESS UNIT RESULTS (ON A REPORTED BASIS)

U.S. Franchised Electric and Gas(USFE&G)

USFE&G reported first-quarter 2011 segment EBIT from continuing operations of $712 million, compared with $744 million in the first quarter of 2010. Results decreased primarily due to less favorable weather in 2011 than 2010, and increases in operation and maintenance costs, most of which were expected. These decreases were partially offset by revenue increases associated with the modernization programs in the Carolinas and in Indiana.

Commercial Power

Commercial Power reported first-quarter 2011 segment EBIT from continuing operations of $91 million, compared to $129 million in the first quarter of 2010. Results reflect the effects of 2010 customer switching in Ohio and lower mark-to-market impacts from economic hedges. These were partially offset by favorable results from the Midwest gas assets due to higher volumes and capacity prices.

Duke Energy International (DEI)

DEI reported first-quarter 2011 segment EBIT from continuing operations of $180 million, compared to $140 million in the first quarter of 2010. DEI's results were driven primarily by a favorable arbitration award in Peru, higher average contract prices in Brazil and favorable average foreign exchange rates.

Other

Other includes corporate governance expenses, costs associated with the company's 2010 voluntary employee separation plan, costs-to-achieve the merger with Progress Energy and results from Duke Energy's captive insurance company.

Other reported a first-quarter 2011 net expense from continuing operations of $45 million, compared to $146 million in the first quarter of 2010. The decrease in net expense was due primarily to prior year severance costs associated with the voluntary employee separation program and office consolidation, a prior year donation to the Duke Energy Foundation and lower corporate governance costs.

INTEREST EXPENSE

Interest expense was $219 million for the first quarter 2011, compared to $210 million for the first quarter 2010. The increase was primarily due to higher debt balances that were the result of financing the company's ongoing construction program.

INCOME TAX EXPENSE

Income tax expense from continuing operations for the first quarter of 2011 was $233 million, compared to $226 million for the first quarter of 2010. The effective tax rate for the quarter was approximately 31 percent as compared to 34 percent in the prior year.

First-quarter 2010 income tax expense included a $17 million charge due to a change in the tax treatment of the Medicare Part D subsidy that was part of health care reform legislation passed last year. The anticipated effective tax rate for 2011 is approximately 32 percent.

NON-GAAP FINANCIAL MEASURES

The primary performance measure used by management to evaluate segment performance is segment EBIT from continuing operations, which at the segment level represents all profits from continuing operations (both operating and non-operating), including any equity in earnings of unconsolidated affiliates, before deducting interest and taxes, and is net of the income attributable to non-controlling interests.

Management believes segment EBIT from continuing operations, which is the GAAP measure used to report segment results, is a good indicator of each segment's operating performance as it represents the results of Duke Energy's ownership interests in continuing operations without regard to financing methods or capital structures. Duke Energy's management uses adjusted diluted EPS, which is a non-GAAP financial measure as it represents diluted EPS from continuing operations attributable to Duke Energy Corporation common shareholders, adjusted for the per-share impact of special items and the mark-to-market impacts of economic hedges in the Commercial Power segment, as a measure to evaluate operations of the company.

Special items represent certain charges and credits, which management believes will not be recurring on a regular basis, although it is reasonably possible such charges and credits could recur. Mark-to-market adjustments reflect the mark-to-market impact of derivative contracts, which is recognized in GAAP earnings immediately as such derivative contracts do not qualify for hedge accounting or regulatory accounting treatment, used in Duke Energy's hedging of a portion of the economic value of its generation assets in the Commercial Power segment. The economic value of the generation assets is subject to fluctuations in fair value due to market price volatility of the input and output commodities (e.g. coal, power) and, as such, the economic hedging involves both purchases and sales of those input and output commodities related to the generation assets. Because the operations of the generation assets are accounted for under the accrual method, management believes that excluding the impact of mark-to-market changes of the economic hedge contracts from adjusted earnings until settlement better matches the financial impacts of the hedge contract with the portion of the economic value of the underlying hedged asset. Management believes that the presentation of adjusted diluted EPS provides useful information to investors, as it provides them an additional relevant comparison of the company's performance across periods. Adjusted diluted EPS is also used as a basis for employee incentive bonuses. The most directly comparable GAAP measure for adjusted diluted EPS is reported diluted EPS from continuing operations attributable to Duke Energy Corporation common shareholders, which includes the impact of special items and the mark-to-market impacts of economic hedges in the Commercial Power segment. Due to the forward-looking nature of adjusted diluted EPS for future periods, information to reconcile such 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 special items and the mark-to-market impacts of economic hedges in the Commercial Power segment for future periods.

Duke Energy also uses adjusted segment EBIT and adjusted Other net expenses as a measure of historical and anticipated future segment and Other performance. When used for future periods, adjusted segment EBIT and adjusted Other net expenses may also include any amounts that may be reported as discontinued operations or extraordinary items. Adjusted segment EBIT and adjusted Other net expenses are non-GAAP financial measures, as they represent reported segment EBIT and Other net expenses adjusted for special items and the mark-to-market impacts of economic hedges in the Commercial Power segment. Management believes that the presentation of adjusted segment EBIT and adjusted Other net expenses provides useful information to investors, as it provides them an additional relevant comparison of a segment's or Other's performance across periods. The most directly comparable GAAP measure for adjusted segment EBIT or adjusted Other net expenses is reported segment EBIT or Other net expenses, which represents segment EBIT and Other net expenses from continuing operations, including any special items and the mark-to-market impacts of economic hedges in the Commercial Power segment. Due to the forward-looking nature of any forecasted adjusted segment EBIT or adjusted Other net expenses 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 special items, the mark-to-market impacts of economic hedges in the Commercial Power segment, or any amounts that may be reported as discontinued operations or extraordinary items for future periods.
