Credit Ratings A-21

Credit Ratings (cont.) A-22

Definitions of Financial Measures "Earnings from ongoing operations" excludes the impact of unusual items. Earnings from ongoing operations should not be considered as an alternative to net income, or reported earnings, which is an indicator of operating performance determined in accordance with GAAP. PPL believes that earnings from ongoing operations, although a non-GAAP measure, is also useful and meaningful to investors because it provides them with PPL's underlying earnings performance as another criterion in making their investment decisions. PPL's management also uses earnings from ongoing operations in measuring certain corporate performance goals. Other companies may use different measures to present financial performance. "Free cash flow before dividends" is derived by deducting the following from cash flow from operations: capital expenditures (net of disposals, but adjusted to include lease financing) and repayment of transition bonds. Free cash flow before dividends should not be considered as an alternative to cash flow from operations, which is determined in accordance with GAAP. PPL believes that free cash flow before dividends is an important measure to both management and investors since it is an indicator of the company's ability to sustain operations and growth without additional outside financing beyond the requirement to fund maturing debt obligations. Other companies may calculate free cash flow before dividends in a different manner. "Funds from Operations," or "FFO," represents cash from operations for PPL, adjusted to exclude cash from operations from PPL Electric Utilities Corporation (PPL Electric) and PPL's U.K. affiliates (WPD) but to include dividends from PPL Electric and WPD; and this total is adjusted to exclude changes in working capital. FFO should not be considered as an alternative to cash flow from operations, which is determined in accordance with GAAP. PPL's calculation of FFO is based on its internal assessment of how a credit rating agency might calculate FFO, and should not be construed as the actual calculation performed by any credit rating agency. The credit rating agencies and other companies may calculate FFO in a different manner. A-23
