 GAAP Disclaimer PSEG presents Operating Earnings in addition to its Net Income reported in accordance with generally accepted accounting principles in the United States (GAAP). Operating Earnings is a non-GAAP financial measure that differs from Net Income because it excludes gains or losses associated with Nuclear Decommissioning Trust (NDT), Mark-to-Market (MTM) accounting, and other material one-time items. PSEG presents Operating Earnings because management believes that it is appropriate for investors to consider results excluding these items in addition to the results reported in accordance with GAAP. PSEG believes that the non-GAAP financial measure of Operating Earnings provides a consistent and comparable measure of performance of its businesses to help shareholders understand performance trends. This information is not intended to be viewed as an alternative to GAAP information. The last page in this presentation (Page A) includes a list of items excluded from Income from Continuing Operations to reconcile to Operating Earnings, with a reference to that slide included on each of the slides where the non-GAAP information appears. 3 |
