(2) Reflects a range of outcomes for the New Mexico Supreme Court appeal of the August 2015 General Rate Case final order. For purposes of writing down the value of the

assets under appeal at Sept. 30, 2016, a 15-month appeal timeframe was used. 2019 average rate base includes: PV2 64MW Acquisition Adjustment (~$75M), PV2 Leasehold Improvements (~$25M) and Balanced Draft Technology (~$50M).

(3) PNM Renewables reflect assets collected through the Renewable Rate Rider. (4) PNM FERC earnings potential reflects a return of 7-9% versus the allowed return of 10%, as FERC formula rate methodology uses prior year average rate base and

provides for mid-year rate increases. (5) 2017 Earnings Potential assumes a forward market price of $29/MWh; a price of $44/MWh is required to break even. PV3 is included in PNM rates beginning in 2018. (6) Consists primarily of Palo Verde Nuclear Decommissioning Trust gains and losses, AFUDC, certain incentive compensation, earnings in 2017 associated with the assets

previously allocated to the Navopache contract, and the 65MW ownership of San Juan Unit 4 beginning in 2018. (7) TNMP Earnings Potential includes $0.02 of Competitive Transition Charge recovery in 2017 and 2018 and $0.01 in 2019. (8) Corporate/Other includes earnings associated with the 65MW ownership of San Juan Unit 4 before PNM assumes ownership in 2018,

short and intermediate term bank debt, and the net impact of Westmoreland financing through NM Capital Utility Corporation.
