(A) The increases in Operating Income at PSEG consolidated and Power in the first and second quarters of 2018 as compared to the same quarters in 2017 were primarily due to higher costs in 2017 related to closing the coal/gas Hudson and Mercer units, which were fully depreciated as of June 1, 2017. The increases in Operating Income at PSEG consolidated and Power in the fourth quarter 2018 as compared to the same quarter in 2017 were primarily due to lower MTM losses and a gain on the sale of the Hudson and Mercer units.

The decreases in Net Income at PSEG consolidated and Power in the fourth quarter 2018 as compared to the same quarter in 2017 also reflected the impact of the one-time benefit recorded in December 2017 as a result of the remeasurement of deferred tax balances and the inclusion in 2018 of net unrealized losses on equity investments in the NDT Fund in accordance with new accounting guidance.
