When excluding the negative effects of the recent federal Tax Cuts and Jobs Act (TCJA), non-GAAP diluted earnings per share increased $0.19 per diluted share to $2.29 per diluted share. Management believes that excluding the effects of the TCJA provides a more meaningful representation of the company's comparative earnings. The Company has adjusted this amount to maintain comparability between periods.

Using Schedule 122, prices go into effect on the resource's in-service date and are updated annually. Upon agreement of the subsequent general rate case the renewable resource is include in base prices and Schedule 122 goes back to zero. Portland General Electric 28#29Decoupling mechanism The decoupling mechanism is intended to allow recovery of margin lost due to a reduction in sales of electricity resulting from customers' energy efficiency and conservation efforts. This includes a Sales Normalization Adjustment (SNA) mechanism for residential and small nonresidential customers (≤ 30 kW) and a Lost Revenue Recovery Adjustment (LRRA), for large nonresidential customers (between 31 kW and 1 MWa). • • The SNA is based on the difference between actual, weather-adjusted usage per customer and that projected in PGE's 2018 general rate case. The SNA mechanism applies to approximately 62% of 2018 base revenues The LRRA is based on the difference between actual energy-efficiency savings (as reported by the ETO) and those incorporated in the applicable load forecast. The LRRA mechanism applies to approximately 26% of 2018 base revenues In PGE's 2016 rate case, PGE and parties stipulated to the extension of the decoupling mechanism for three years, through the end of 2019. In addition, the use-per-customer baseline was adjusted for new connects with lower energy usage.
