Exhibit 99

GAAP Disclaimer

PSEG presents Operating Earnings in addition to its Net Income reported in

accordance with accounting principles generally accepted 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 two slides in this presentation include 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.
