2006 Earnings-per-share Incentive Target Measure

Duke Energy’s 2005 Summary Annual Report includes a discussion of the company’s 2006 EPS incentive target of $1.90. This EPS measure is used for employee incentive bonuses and should track ongoing diluted EPS, which is a non-GAAP financial measure as it represents diluted EPS from continuing operations plus the per-share effect of any discontinued operations from the company’s Crescent Resources real estate unit, adjusted for the per-share impact of special items. Special items represent certain charges and credits which management believes will not be recurring on a regular basis. The most directly comparable GAAP measure for ongoing diluted EPS is reported diluted EPS from continuing operations, which includes the impact of special items. Due to the forward-looking nature of this non-GAAP financial measure, information to reconcile it to the most directly comparable GAAP financial measure is not available at this time, as the company is unable to project any special items for 2006.

2006 and Beyond Ongoing Segment EBIT and Related Growth Percentages

Duke Energy’s 2005 Summary Annual Report includes discussion of forecasted ongoing EBIT for 2006 for certain segments, including a discussion of ongoing equity earnings for Duke Energy Field Services and, for Duke Energy Gas Transmission, a discussion of forecasted ongoing segment EBIT growth rates, which are based on historical and forecasted ongoing segment EBIT.

Ongoing segment EBIT and related growth rates are non-GAAP financial measures, as they represent reported segment EBIT adjusted for special items, which represent certain charges and credits which management believes will not be recurring on a regular basis. The most directly comparable GAAP measure for ongoing segment EBIT is reported segment EBIT, which represents EBIT from continuing operations, including any special items. Due to the forward-looking nature of forecasted ongoing segment EBIT and 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 project special items for any future periods.

2006 Ongoing Segment EBIT for Crescent Resources

Duke Energy’s 2005 Summary Annual Report includes a discussion of Crescent Resources’ forecasted ongoing segment EBIT from continuing and discontinued operations for 2006. As the company’s segment GAAP measure is EBIT from continuing operations, the combination of segment EBIT from continuing and discontinued operations represents a non-GAAP financial measure. The most directly comparable GAAP measure for Crescent’s segment EBIT from continuing and discontinued operations is reported segment EBIT from continuing operations. Information to reconcile this non-GAAP financial measure to the most directly comparable GAAP financial measure is not available at this time, as the company is unable to forecast which Crescent operations, if any, will be discontinued operations during 2006.

2007 Ongoing Diluted EPS and Related Future Growth Percentages

Duke Energy’s 2005 Summary Annual Report includes a discussion of forecasted 2007 ongoing diluted EPS and related forecasted growth percentages thereafter.

Due to the forward-looking nature of ongoing diluted EPS for future periods, information to reconcile this non-GAAP financial measure to the most directly comparable GAAP financial measure is not available at this time, as the company is unable to forecast any special items for 2007 or for any future periods.
