Definitions of Non-GAAP Financial Measures ppl Management utilizes "Earnings from Ongoing Operations" or "Ongoing Earnings" as a non-GAAP financial measure that should not be considered as an alternative to reported earnings, or net income, an indicator of operating performance determined in accordance with GAAP. PPL believes that Earnings from Ongoing Operations is useful and meaningful to investors because it provides management's view of PPL's earnings performance as another criterion in making investment decisions. In addition, PPL's management uses Earnings from Ongoing Operations in measuring achievement of certain corporate performance goals, including targets for certain executive incentive compensation. Other companies may use different measures to present financial performance. Earnings from Ongoing Operations is adjusted for the impact of special items. Special items are presented in the financial tables on an after-tax basis with the related income taxes on special items separately disclosed. Income taxes on special items, when applicable, are calculated based on the statutory tax rate of the entity where the activity is recorded. Special items may include items such as: • Gains and losses on sales of assets not in the ordinary course of business. • Impairment charges. • . • Significant workforce reduction and other restructuring effects. Acquisition and divestiture-related adjustments. Significant losses on early extinguishment of debt. Other charges or credits that are, in management's view, non-recurring or otherwise not reflective of the company's ongoing operations. 37
