PUBLIC SERVICE COMPANY OF NEW MEXICO AND SUBSIDIARIES

TEXAS-NEW MEXICO POWER COMPANY AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(1) Significant Accounting Policies and Responsibility for Financial Statements

Financial Statement Preparation

In the opinion of management, the accompanying unaudited interim Condensed Consolidated Financial Statements reflect all normal and recurring accruals and adjustments that are necessary to present fairly the consolidated financial position at March 31, 2013 and December 31, 2012, and the consolidated results of operations, comprehensive income, and consolidated cash flows for the three months ended March 31, 2013 and 2012. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could ultimately differ from those estimated. The Notes to Condensed Consolidated Financial Statements include disclosures for PNMR, PNM, and TNMP. This report uses the term “Company” when discussing matters of common applicability to PNMR, PNM, and TNMP. Discussions regarding only PNMR, PNM, or TNMP are so indicated. Certain amounts in the 2012 Condensed Consolidated Financial Statements and Notes thereto have been reclassified to conform to the 2013 financial statement presentation.

These Condensed Consolidated Financial Statements are unaudited. Certain information and note disclosures normally included in the annual Consolidated Financial Statements have been condensed or omitted, as permitted under the applicable rules and regulations. Readers of these financial statements should refer to PNMR’s, PNM’s, and TNMP’s audited Consolidated Financial Statements and Notes thereto that are included in their respective 2012 Annual Reports on Form 10-K. Weather causes the Company’s results of operations to be seasonal in nature and the results of operations presented in the accompanying Condensed Consolidated Financial Statements are not necessarily representative of operations for an entire year.

GAAP defines subsequent events as events or transactions that occur after the balance sheet date but before financial statements are issued or are available to be issued. Based on their nature, magnitude, and timing, certain subsequent events may be required to be reflected at the balance sheet date and/or required to be disclosed in the financial statements. The Company has evaluated subsequent events as required by GAAP.

Principles of Consolidation

The Condensed Consolidated Financial Statements of each of PNMR, PNM, and TNMP include their accounts and those of subsidiaries in which that entity owns a majority voting interest. PNM also consolidates the PVNGS Capital Trust and Valencia. PNM owns undivided interests in several jointly-owned power plants and records its pro-rata share of the assets, liabilities, and expenses for those plants.

PNMR shared services' administrative and general expenses, which represent costs that are primarily driven by corporate level activities, are charged to the business segments at cost. Other significant intercompany transactions between PNMR, PNM, and TNMP include interest and income tax sharing payments, as well as dividends paid on common stock. All intercompany transactions and balances have been eliminated. See Note 11.

(2) Segment Information

The following segment presentation is based on the methodology that management uses for making operating decisions and assessing performance of its various business activities. A reconciliation of the segment presentation to the GAAP financial statements is provided.

PNM

PNM includes the retail electric utility operations of PNM that are subject to traditional rate regulation by the NMPRC. PNM provides integrated electricity services that include the generation, transmission, and distribution of electricity for retail electric customers in New Mexico. PNM also provides generation service to firm-requirements wholesale customers and sells electricity into the general wholesale market, as well as providing transmission services to third parties. The sale of electricity

into the wholesale market includes the optimization of PNM's jurisdictional capacity, as well as the capacity excluded from retail rates. FERC has jurisdiction over wholesale and transmission rates.

TNMP

TNMP is an electric utility providing regulated transmission and distribution services in Texas under the TECA. TNMP's operations are subject to traditional rate regulation by the PUCT.

Corporate and Other

The Corporate and Other segment includes PNMR holding company activities, primarily related to corporate level debt and PNMR Services Company.

The following tables present summarized financial information for PNMR by segment. PNM and TNMP each operate in only one segment. Therefore, tabular segment information is not presented for PNM and TNMP.

(3) Variable Interest Entities

GAAP determines how an enterprise evaluates and accounts for its involvement with variable interest entities, including determining the primary beneficiary of a variable interest entity, by focusing primarily on whether the enterprise has the power to direct the activities that most significantly impact the economic performance of a variable interest entity. GAAP also requires continual reassessment of the primary beneficiary of a variable interest entity. Additional information concerning PNM's variable interest entities is contained in Note 9 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Valencia

PNM has a PPA to purchase all of the electric capacity and energy from Valencia, a 145 MW natural gas-fired power plant near Belen, New Mexico, through May 2028. A third-party built, owns, and operates the facility while PNM is the sole purchaser of the electricity generated. PNM is obligated to pay fixed operations and maintenance and capacity charges in addition to variable operations and maintenance charges under this PPA. For the three months ended March 31, 2013 and 2012, PNM paid $4.7 million and $4.6 million for fixed charges and $0.1 million and $0.1 million for variable charges. PNM does not have any other financial obligations related to Valencia. The assets of Valencia can only be used to satisfy obligations of Valencia and creditors of Valencia do not have any recourse against PNM’s assets. PNM has concluded that the third party entity that owns Valencia is a variable interest entity and that PNM is the primary beneficiary of the entity under GAAP. As the primary beneficiary, PNM consolidates the entity in its financial statements. The assets and liabilities of Valencia set forth below are immaterial to PNM and, therefore, not shown separately on the Condensed Consolidated Balance Sheets. The owner's equity and net income of Valencia are considered attributable to non-controlling interest.

PVNGS Leases

PNM leases interests in Units 1 and 2 of PVNGS under arrangements, which were entered into in 1985 and 1986, that are accounted for as operating leases. PNM is not the legal or tax owner of the leased assets. PNM has an option to purchase the leased assets at appraised value at the end of the leases, but does not have a fixed price purchase option and does not provide residual value guarantees. As set forth in the leases, PNM has options to renew the leases at fixed rates, which represent 50% of the amounts during the original terms of the leases, for two years beyond the termination of the original lease terms. The option periods on all of the Unit 1 leases and one of the Unit 2 leases, amounting to 14% of the Unit 2 capacity under lease, may be further extended for up to an additional six years (the “Maximum Option Period”) if the appraised remaining useful lives and fair value of the leased assets are greater than parameters set forth in the leases. As discussed in Note 9 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K, PNM notified each of the lessors of the Unit 1 leases that it will extend each Unit 1 lease for the Maximum Option Period upon the expiration of the basic lease term on January 15, 2015. In addition, PNM notified each of the lessors in the Unit 2 leases that PNM will “retain” the assets leased under that lease upon the expiration of the basic lease term on January 15, 2016. PNM will be required to specify by notice to each of the lessors by January 15, 2014, whether on January 15, 2016 it will extend the Unit 2 leases or purchase the leased assets.

PNM is only obligated to make payments to the trusts for the scheduled semi-annual lease payments, which, net of amounts that will be returned to PNM through its ownership in related lessor notes, aggregate $65.9 million as of March 31, 2013 over the remaining original terms of the leases. Under certain circumstances (for example, final shutdown of the plant, the NRC issuing specified violation orders with respect to PVNGS, or the occurrence of specified nuclear events), PNM would be required to make specified payments to the beneficial owners and take title to the leased interests. If such an event had occurred as of March 31, 2013, PNM could have been required to pay the beneficial owners up to $160.4 million, which would result in PNM taking ownership of the leased assets and termination of the leases. PNM has no other financial obligations or commitments to the trusts or the beneficial owners. Creditors of the trusts have no recourse to PNM’s assets other than with respect to the contractual lease payments. PNM has no additional rights to the assets of the trusts other than the use of the leased assets.

PNM has evaluated the PVNGS lease arrangements, including the notices discussed above, and concluded that it does not have the power to direct the activities that most significantly impact the economic performance of the trusts and, therefore, is not the primary beneficiary of the trusts under GAAP. PNM has recorded no assets or liabilities related to the trusts other than the accrual of lease payments between the scheduled payment dates, which were $11.8 million at March 31, 2013 and $26.0 million at December 31, 2012 and are included in other current liabilities on the Condensed Consolidated Balance Sheets. For additional information regarding these leases, see Risk Factors, MD&A – Off Balance Sheet Arrangements and Note 7 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Delta

PNM has a PPA covering the entire output of Delta, which is a variable interest under GAAP. PNM makes fixed and variable payments to Delta under the PPA. PNM also controls the dispatch of the generating plant, which impacts the variable payments made under the PPA and impacts the economic performance of the entity that owns Delta. PNM makes fixed and variable payments to Delta under the PPA. For the three months ended March 31, 2013 and 2012, PNM incurred fixed capacity charges of $1.6 million and $1.5 million and variable energy charges of $0.2 million and $0.1 million under the PPA. PNM’s only quantifiable obligation under the PPA is to make the fixed payments, which as of March 31, 2013, aggregated $43.7 million through the end of the PPA in 2020. PNM will also pay variable costs, which cannot be quantified since the amounts are based on how much the generating plant is in operation.

This arrangement was entered into prior to December 31, 2003 and PNM was unsuccessful in obtaining the information necessary to determine if it is the primary beneficiary of the entity that owns Delta, or to consolidate that entity if it were determined that PNM is the primary beneficiary. Accordingly, PNM was unable to make those determinations and, as provided in GAAP, accounted for this PPA as an operating lease.

In December 2012, PNM entered into an agreement with the owners of Delta under which PNM would purchase the entity that owns Delta. At closing PNM would make a cash payment of $23.0 million, which would be adjusted for actual working capital compared to a targeted working capital and certain prepayments of debt. Delta had project financing debt of $18.5 million at March 31, 2013, including $3.0 million due by March 31, 2014, which PNM would retire at closing of the purchase. The purchase is subject to approval of the NMPRC and FERC, as well as other customary closing conditions. Furthermore, closing is subject to the seller remedying specified operational, NERC compliance, and environmental issues. FERC approved the purchase on February 26, 2013.

Delta informed PNM that at March 31, 2013, it had total assets of $26.1 million, including net property, plant, and equipment of $22.4 million, and total liabilities of $20.4 million. Delta also indicated its revenue for the three months ended March 31, 2013 was $1.8 million and its net earnings were $0.2 million. Consolidation of Delta would be immaterial to the Condensed Consolidated Balance Sheets of PNMR and PNM. Since all of Delta's revenues and expenses are attributable to its PPA arrangement with PNM, the primary impact of consolidating Delta to the Condensed Consolidated Statements of Earnings of PNMR and PNM would be to reclassify Delta's net earnings from operating expenses and reflect such amount as earnings attributable to a non-controlling interest, without any impact to net earnings attributable to PNMR and PNM.

(4) Fair Value of Derivative and Other Financial Instruments

Energy Related Derivative Contracts

Overview

The primary objective for the use of derivative instruments, including energy contracts, options, and futures, is to manage price risk associated with forecasted purchases of energy and fuel used to generate electricity, as well as managing anticipated generation capacity in excess of forecasted demand from existing customers. The Company's energy related derivative contracts manage commodity risk. PNM is required to meet the demand and energy needs of its retail and firm-requirements wholesale customers. PNM is exposed to market risk for its share of PVNGS Unit 3 and the needs of its firm-requirements wholesale customers not covered under a FPPAC. PNM’s operations are managed primarily through a net asset-backed strategy, whereby PNM’s aggregate net open forward contract position is covered by its forecasted excess generation capabilities or market purchases. PNM could be exposed to market risk if its generation capabilities were to be disrupted or if its load requirements were to be

greater than anticipated, to the extent not covered by the FPPAC. If all or a portion of load requirements were required to be covered as a result of such unexpected situations, commitments would have to be met through market purchases. Additional information concerning the Company's energy related derivative contracts, including how commodity risk is managed, is contained in Note 8 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Commodity Risk

Marketing and procurement of energy often involve market risks associated with managing energy commodities and establishing open positions in the energy markets, primarily on a short-term basis. PNM routinely enters into various derivative instruments such as forward contracts, option agreements, and price basis swap agreements to economically hedge price and volume risk on power commitments and fuel requirements and to minimize the effect of market fluctuations in wholesale portfolios. PNM monitors the market risk of its commodity contracts using VaR calculations to maintain total exposure within management-prescribed limits in accordance with approved risk and credit policies.

Accounting for Derivatives

Under derivative accounting and related rules for energy contracts, the Company accounts for its various derivative instruments for the purchase and sale of energy based on the Company’s intent. Energy contracts that meet the definition of a derivative under GAAP and do not qualify, or are not designated, for the normal sales and purchases exception are recorded on the balance sheet at fair value at each period end. The changes in fair value are recognized in earnings unless specific hedge accounting criteria are met and elected. Normal sales and purchases are not marked to market and are reflected in results of operations when the underlying transactions settle.

During the three months ended March 31, 2013 and the year ended December 31, 2012, the Company was not hedging its exposure to the variability in future cash flows from commodity derivatives through designated cash flows hedges. The contracts recorded at fair value that do not qualify or are not designated for cash flow hedge accounting are classified as economic hedges. Economic hedges are defined as derivative instruments, including long-term power agreements, used to economically hedge generation assets, purchased power and fuel costs, and customer load requirements. Changes in the fair value of economic hedges are reflected in results of operations and are classified between operating revenues and cost of energy according to the intent of the hedge. The Company has no trading transactions.

Fair value is defined under GAAP as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value is based on current market quotes as available and is supplemented by modeling techniques and assumptions made by the Company to the extent quoted market prices or volatilities are not available. External pricing input availability varies based on commodity location, market liquidity, and term of the agreement. Valuations of derivative assets and liabilities take into account nonperformance risk including the effect of counterparties' and the Company’s credit risk. The Company regularly assesses the validity and availability of pricing data for its derivative transactions. Although the Company uses its best judgment in estimating the fair value of these instruments, there are inherent limitations in any estimation technique.

Certain of PNM's commodity derivative instruments included in the above table are subject to master netting agreements whereby assets and liabilities could be offset in the settlement process. The Company does not offset fair value, cash collateral, and accrued payable or receivable amounts recognized for derivative instruments under master netting arrangements and the above table reflects the gross amounts of assets and liabilities. The amounts that could be offset under master netting agreements were immaterial at March 31, 2013 and December 31, 2012.

At March 31, 2013 and December 31, 2012, PNMR and PNM had no amounts recognized for the legal right to reclaim cash collateral. In addition, at March 31, 2013 and December 31, 2012, amounts posted as cash collateral under margin arrangements were $1.9 million and $1.9 million for both PNMR and PNM. PNMR and PNM had no obligation to return cash collateral at March 31, 2013 and December 31, 2012. Cash collateral amounts are included in other current assets on the Condensed Consolidated Balance Sheets.

PNM has a NMPRC approved hedging plan to manage fuel and purchased power costs related to customers covered by its FPPAC. The table above includes less than $0.1 million of current assets and current liabilities at March 31, 2013 and December 31, 2012 related to this plan. The offsets to these amounts are recorded as regulatory assets and liabilities on the Condensed Consolidated Balance Sheets.

In connection with managing its commodity risks, the Company enters into master agreements with certain counterparties. If the Company is in a net liability position under an agreement, some agreements provide that the counterparties can request collateral from the Company if the Company’s credit rating is downgraded; other agreements provide that the counterparty may request collateral to provide it with “adequate assurance” that the Company will perform; and others have no provision for collateral.

The table below presents information about the Company’s contingent requirements to provide collateral under commodity contracts having an objectively determinable collateral provision that are in net liability positions and are not fully collateralized with cash. Contractual liability represents commodity derivative contracts recorded at fair value on the balance sheet, determined on an individual contract basis without offsetting amounts for individual contracts that are in an asset position and could be offset under master netting agreements with the same counterparty. The table only reflects cash collateral that has been posted under the existing contracts and does not reflect letters of credit under the Company’s revolving credit facilities that have been issued as collateral. Net exposure is the net contractual liability for all contracts, including those designated as normal purchases and sales, offset by existing cash collateral and by any offsets available under master netting agreements, including both asset and liability positions.

Fair Value Disclosures

The Company determines the fair values of its derivative and other instruments based on the hierarchy established in GAAP, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. GAAP describes three levels of inputs that may be used to measure fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. Level 3 inputs used in determining fair values for the Company consist of internal valuation models.

For the NDT and reclamation trust investments, Level 2 fair values are provided by the trustee utilizing a pricing service. The pricing provider predominantly uses the market approach using bid side market value based upon a hierarchy of information for specific securities or securities with similar characteristics. For commodity derivatives, Level 2 fair values are determined based on market observable inputs, which are validated using multiple broker quotes, including forward price, volatility, and interest rate curves to establish expectations of future prices. Credit valuation adjustments are made for estimated credit losses based on the overall exposure to each counterparty. For long-term debt, Level 2 fair values are provided by an external pricing service. The pricing service primarily utilizes quoted prices for similar debt in active markets when determining fair value. For investments categorized as Level 3, primarily the PVNGS lessor notes and other investments, fair values were determined by discounted cash flow models that take into consideration discount rates that are observable for similar type assets and liabilities. Management of the Company independently verifies the information provided by pricing services.

The Company records any transfers between fair value hierarchy levels as of the end of each calendar quarter. There were no transfers between levels during the three months ended March 31, 2013 and 2012.

(6) Stock-Based Compensation

PNMR has various stock-based compensation programs, including stock options, restricted stock, and performance shares granted under the Performance Equity Plan (“PEP”). In 2011, the Company changed its approach to awarding stock-based compensation. As a result, no stock options have been granted in 2013 or 2012 and awards of restricted stock have increased. Certain restricted stock awards are subject to achieving performance or market targets and some also have time vesting requirements. Other awards of restricted stock are only subject to time vesting requirements. Additional information concerning stock-based compensation under PNMR's Performance Equity Plan ("PEP") is contained in Note 13 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Restricted stock under the PEP refers to awards of stock subject to vesting, performance, or market conditions rather than to shares with contractual post-vesting restrictions. Generally, the awards vest ratably over three years from the grant date of the award. However, certain awards with performance or market conditions vest upon satisfaction of those conditions. In addition, plan provisions provide that upon retirement, participants become 100% vested in stock awards.

The stock-based compensation expense related to stock options and restricted stock awards without performance or market conditions is amortized to compensation expense over the requisite vesting period, which is generally three years. However, compensation expense for awards to participants that are retirement eligible on the award date is recognized immediately at the award date and is not amortized. Compensation expense for performance-based shares is recognized ratably over the performance period and is adjusted periodically to reflect the level of achievement expected to be attained. Compensation expense related to market-based shares is recognized ratably over the measurement period, regardless of the actual level of achievement, provided the employees remain with the Company during the period. At March 31, 2013 and December 31, 2012, PNMR had unrecognized expense related to stock awards of $6.8 million and $3.8 million. 

The Company uses the Black Scholes option pricing model to estimate the fair value of stock option awards based on multiple factors, including historical exercise patterns of employees in relatively homogeneous groups with respect to exercise

and post-vesting employment termination behaviors, expected exercising patterns for these same homogeneous groups, and both the implied and historical volatility of PNMR's stock price. The grant date fair value for restricted stock and stock awards with Company internal performance targets is determined based on the market price of PNMR common stock on the date of the agreements reduced by the present value of future dividends, which will not be received prior to vesting, applied to the total number of shares that are anticipated to vest, although the number of shares that ultimately vest cannot be determined until after the performance periods end. The grant date fair value of stock awards with market targets is determined using Monte Carlo simulation models, which provide grant date fair values that include an expectation of the number of shares to vest.

The following table summarizes the weighted-average assumptions used to determine the awards grant date fair value:

	Three Months Ended March 31,
Restricted Shares and Performance Based Shares	2013			2012
Expected quarterly dividends per share	$	0.165		$	0.145
Risk-free interest rate	0.38		%	0.69		%
Market-Based Shares
Dividend yield	2.86		%	3.45		%
Expected volatility	25.11		%	43.98		%
Risk-free interest rate	0.36		%	1.04		%

The following table summarizes activity in stock options and restricted stock awards, including performance-based and market-based shares, for the three months endedMarch 31, 2013:

	Stock Option Shares		Weighted- Average Exercise Price		Restricted Stock		Weighted- Average Grant Date Fair Value
Outstanding at beginning of period	1,992,700		$	20.72	353,722		$	14.03

Included as granted and exercised in the tables above are 100,953 shares that were based upon achieving performance or market targets for 2012. The Board approved these shares in February 2013, including shares with market targets at near maximum levels.

PNMR also has share agreements that provide for performance or market targets through 2015. Excluded from the above tables are maximums of 188,129, 198,369, and 179,811 shares for periods ending in 2013, 2014, and 2015 that would be awarded if all performance or market criteria are achieved and all executives remain eligible.

In March 2012, the Company entered into a retention award agreement with its Chairman, President, and Chief Executive Officer under which she would receive 135,000 shares of PNMR's common stock if the Company meets specific market targets at the end of 2016 and she remains an employee of the Company. If the Company achieves specific market targets at the end of 2014 and she remains an employee of the Company, she would receive 35,000 of the total shares at that time. The retention award was made under the PEP and was approved by the Board on February 28, 2012. The above tables do not include any shares under the retention award agreement.

At March 31, 2013, the aggregate intrinsic values of stock options outstanding and exercisable were $7.8 million and $7.7 million with weighted-average remaining contract lives of 4.06 and 4.05 years. At March 31, 2013, the exercise price of 827,977 outstanding stock options is greater than the closing price of PNMR common stock on that date; therefore, those options have no intrinsic value.

The following table provides additional information concerning stock options and restricted stock activity, including performance-based and market-based shares:

Additional information concerning financing activities, including a TNMP cash-flow hedge that establishes a fixed interest rate on a variable rate loan, is contained in Note 6 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Short-term Debt

PNMR has a revolving credit financing capacity of $300.0 million under the PNMR Revolving Credit Facility. PNM has a revolving credit financing capacity of $400.0 million under the PNM Revolving Credit Facility. Both of these facilities currently expire on October 31, 2017 and provide for an additional one-year extension option, subject to approval by the lenders. PNMR borrowed $100.0 million under the PNMR Term Loan Agreement in December 2012. TNMP has a revolving credit facility with financing capacity of $75.0 million under the TNMP Revolving Credit Facility that expires in December 2015. At March 31, 2013, the weighted average interest rate was 1.96% for borrowings outstanding under the PNMR Revolving Credit Facility, 1.335% for the PNMR Term Loan Agreement, 1.71% for the PNM Revolving Credit Facility, and 1.83% for the TNMP Revolving Credit Facility. Short-term debt outstanding consisted of:

from PNMR under their intercompany loan agreement. At May 1, 2013, PNMR, PNM and TNMP had consolidated invested cash of $4.5 million, none, and none.

Financing Activities

On March 6, 2013, TNMP commenced an offer to exchange any and all of TNMP's $265.5 million aggregate principal amount outstanding 9.50% First Mortgage Bonds, due 2019, Series 2009A, for a new series of 6.95% First Mortgage Bonds, due 2043, Series 2013A, and up to $140 in cash for each $1,000 of bonds exchanged. Settlement of the exchange offer occurred on April 3, 2013. Upon settlement, TNMP issued $93.2 million of 6.95% First Mortgage Bonds and paid an aggregate of $13.0 million in cash in exchange for $93.2 million of 9.50% First Mortgage Bonds, in addition to payment of accrued and unpaid interest on the exchanged bonds. The exchange will result in the recording of a $23.2 million premium on the 6.95% First Mortgage Bonds reflecting the contractual interest rate being in excess of the market rate of interest on the date of the exchange. A regulatory asset will be recorded to offset the premium, as well as the cash consideration paid in the exchange.

On April 22, 2013, PNM entered into a $75.0 million Term Loan Agreement (the “PNM Term Loan Agreement”) among PNM, the lenders identified therein, and Union Bank, N.A., as Administrative Agent. Funding of the PNM Term Loan Agreement occurred on April 22, 2013, at which time the funds were used to repay $75.0 million in borrowings made under the PNM Revolving Credit Facility. The PNM Term Loan Agreement bears interest at a variable rate and must be repaid on or before October 21, 2014. The PNM Term Loan Agreement includes customary covenants, including requirements to not exceed a maximum consolidated debt-to-consolidated capitalization ratio and customary events of default. The PNM Term Loan Agreement has a cross default provision and a change of control provision.

(8) Pension and Other Postretirement Benefit Plans

PNMR and its subsidiaries maintain qualified defined benefit pension plans, postretirement benefit plans providing medical and dental benefits, and executive retirement programs (“PNM Plans” and “TNMP Plans”). PNMR maintains the legal obligation for the benefits owed to participants under these plans.

Additional information concerning pension and OPEB plans is contained in Note 12 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K. Annual net periodic benefit cost (income) for the plans is actuarially determined using the methods and assumptions set forth in that note and is recognized ratably throughout the year.

PNM made contributions to its pension plan trust of $60.0 million and $77.7 million in the three months ended March 31, 2013 and 2012. PNM does not anticipate making additional contributions to its pension trust in 2013.  Based on current law, including recent amendments to funding requirements, and estimates of portfolio performance, PNM estimates minimum required contributions for its pension plan trust would total $49.1 million for 2014-2017. Minimum required contributions were developed using current funding assumptions, including discount rates of 4.8% to 5.2%. Actual amounts required to be funded in the future will depend on the actuarial assumptions at that time, including the appropriate discount rate. PNM may make additional contributions at its discretion. PNM made contributions to the OPEB trust of $0.5 million and $0.8 million in the three months ended March 31, 2013 and 2012. PNM expects contributions during 2013 to the OPEB trust to total $3.3 million.  Disbursements under the executive retirement program, which are funded by PNM and considered to be contributions to the plan, were $0.4 million in the three months ended March 31, 2013 and 2012 and are expected to total $1.5 million during 2013.

TNMP does not anticipate making additional contributions to its pension trust in 2013. Based on current law, including recent amendments to funding requirements, and estimates of portfolio performance, TNMP estimates there would be no minimum required contributions to its pension plan trust for 2014-2017. Minimum required contributions were developed using current funding assumptions, including discount rates of 4.8% and 5.2%. Actual amounts to be funded in the future will depend on the actuarial assumptions at that time, including the appropriate discount rate. TNMP may make additional contributions at its discretion. TNMP made contributions to the OPEB trust of zero and $0.3 million in the three months ended March 31, 2013 and 2012. TNMP expects contributions during 2013 to the OPEB trust to total $0.3 million. Disbursements under the executive retirement program, which are funded by TNMP and considered to be contributions to the plan, were less than $0.1 million in the three months ended March 31, 2013 and 2012 and are expected to total $0.1 million during 2013.

With respect to some of the items listed below, the Company has determined that a loss is not probable or that, to the extent probable, cannot be reasonably estimated. In some cases, the Company is not able to predict with any degree of certainty the range of possible loss that could be incurred. Notwithstanding these facts, the Company has assessed these matters based on current information and made judgments concerning their potential outcome, giving due consideration to the nature of the claim, the amount and nature of damages sought, and the probability of success. Such judgments are made with the understanding that the outcome of any litigation, investigation, and other legal proceeding is inherently uncertain. In accordance with GAAP, the Company records liabilities for matters where it is probable a loss has been incurred and the amount of loss is reasonably estimable. The actual outcomes of the items listed below could ultimately differ from the judgments made and the differences could be material. The Company cannot make any assurances that the amount of reserves or potential insurance coverage will be sufficient to cover the cash obligations that might be incurred as a result of litigation or regulatory proceedings. The Company does not expect that any known lawsuits, environmental costs, and commitments will have a material effect on its financial condition, results of operations, or cash flows.

Additional information concerning commitments and contingencies is contained in Note 16 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Commitments and Contingencies Related to the Environment

Nuclear Spent Fuel and Waste Disposal

Nuclear power plant operators are required to enter into spent fuel disposal contracts with the DOE that require the DOE to accept and dispose of all spent nuclear fuel and other high-level radioactive wastes generated by domestic power reactors. Although the Nuclear Waste Policy Act required the DOE to develop a permanent repository for the storage and disposal of spent nuclear fuel by 1998, the DOE announced that it would not be able to open the repository by 1998 and sought to excuse its performance under the contract. In November 1997, the D.C. Circuit issued a decision preventing the DOE from excusing its own delay, but refused to order the DOE to begin accepting spent nuclear fuel. Based on this decision and the DOE's delay, a number of utilities, including APS (on behalf of itself and the other PVNGS owners, including PNM), filed damages actions against the DOE in the Court of Federal Claims. The PVNGS owners previously received a damages award for costs incurred through December 2006. APS filed a subsequent lawsuit, on behalf of itself and the other PVNGS owners, against DOE in the Court of Federal Claims on December 19, 2012. The lawsuit alleges that from January 1, 2007, through June 30, 2011, APS, as a co-owner of PVNGS, incurred additional damages due to DOE's continuing failure to remove spent nuclear fuel and high level waste from PVNGS. PNM is unable to predict the outcome of this matter. PNM estimates that it will incur approximately $42.8 million (in 2010 dollars) for its share of the costs related to the on-site interim storage of spent nuclear fuel at PVNGS during the term of the operating licenses. PNM accrues these costs as a component of fuel expense as the fuel is consumed. At March 31, 2013 and December 31, 2012, PNM had a liability for interim storage costs of $12.6 million and $13.9 million included in other deferred credits.

On June 8, 2012, the D.C. Circuit issued its decision on a challenge by several states and environmental groups of the NRC's rulemaking regarding temporary storage and permanent disposal of high-level nuclear waste and spent nuclear fuel. The petitioners had challenged the NRC's 2010 update to the agency's Waste Confidence Decision. The D.C. Circuit found that the agency's 2010 Waste Confidence Decision update constituted a major federal action, which requires either an environmental impact statement or a finding of no significant impact from the agency's actions. The D.C. Circuit found that the NRC's evaluation of the environmental risks from spent nuclear was deficient, and therefore remanded the 2010 Waste Confidence Decision update for further action. In September 2012, the NRC issued a directive to its staff to proceed with development of a generic environmental impact statement to support an updated Waste Confidence Decision within 24 months. PNM is unable to predict the impact that the decision may have on the operation of PVNGS.

The Clean Air Act

Regional Haze

In 1999, EPA developed a regional haze program and regional haze rules under the CAA. The rule directs each of the 50 states to address regional haze. Pursuant to the CAA, states have the primary role to regulate visibility requirements by promulgating

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

SIPs. States are required to establish goals for improving visibility in national parks and wilderness areas (also known as Class I areas) and to develop long-term strategies for reducing emissions of air pollutants that cause visibility impairment in their own states and for preventing degradation in other states. States must establish a series of interim goals to ensure continued progress. The first planning period specifies setting reasonable progress goals for improving visibility in Class I areas by the year 2018. In July 2005, the EPA promulgated its final regional haze rule guidelines for states to conduct BART determinations for certain covered facilities, including utility boilers, built between 1962 and 1977 that have the potential to emit more than 250 tons per year of visibility impairing pollution. If it is demonstrated that the emissions from these sources cause or contribute to visibility impairment in any Class I area, then BART must be installed by 2018.

SJGS

SJGS is a source that is subject to the statutory obligations of the CAA to reduce visibility impacts. The State of New Mexico submitted its SIP on the regional haze and interstate transport elements of the visibility rules for review by EPA in June 2011. The SIP found that BART to reduce NOx emissions from SJGS is selective non-catalytic reduction technology (“SNCR”). Nevertheless, in August 2011, EPA published its FIP, stating that it was required to do so by virtue of a consent decree it had entered into with an environmental group in litigation concerning the interstate transport requirements of the CAA. The FIP included a regional haze BART determination for SJGS that requires installation of selective catalytic reduction technology (“SCR”) with stringent NOx emission limits on all four units by September 21, 2016.

PNM, the Governor of New Mexico, and NMED petitioned the Tenth Circuit to review EPA's decision and requested EPA to reconsider its decision. The Tenth Circuit denied petitions to stay the effective date of the rule on March 1, 2012. These parties have also formally asked EPA to stay the effective date of the rule. Several environmental groups have intervened in support of EPA. WEG also filed an action to challenge EPA's rule in the Tenth Circuit, seeking to shorten its compliance period from five years to three years and PNM has intervened in this action. Oral arguments on the merits of the FIP challenges were held in October 2012 in the Tenth Circuit. In accordance with the court's order, the parties have filed supplemental information. No decision has been announced and there is no deadline for a court decision.

In litigation involving several environmental groups, the United States District Court for the District of Columbia entered a consent decree, which, as amended, required EPA to issue a final rulemaking on New Mexico's regional haze SIP by November 15, 2012. EPA approved all components of the SIP, except for the NOx BART determination for SJGS. With respect to that element of the SIP, EPA determined that with the FIP in place, it had met its obligation under the consent decree.

Because the unchanged compliance deadline of the FIP required PNM to continue to take steps to commence installation of SCRs at SJGS, PNM entered into a contract in October 2012 with an engineering, procurement, and construction contractor to install SCRs on behalf of the SJGS owners. The construction contract, which includes termination provisions in the event that SCRs are determined in the future to be unnecessary, has been suspended through November 1, 2014. PNM estimated the total cost to install SCRs on all four units of SJGS to be between approximately $824 million and $910 million, which amounts include costs for construction management, gross receipts taxes, AFUDC, and other PNM costs, although final costs would be refined through an “open book” subcontractor bidding process. The costs for the project to install SCRs would encompass installation of technology to comply with the NAAQS requirements described below.

PNM previously indicated it estimated the cost of SNCRs on all four units of SJGS to be between approximately $85 million and $90 million based on a conceptual design study. Along with the SNCR installation, additional equipment would be required to be installed to meet the NAAQS requirements described below, the cost of which had been estimated to total between approximately $105 million and $110 million for all four units of SJGS. The estimates for SNCRs and the NAAQS requirements include gross receipts taxes, AFUDC, and other PNM costs.

Based upon its current SJGS ownership interest, PNM's share of the costs under either SCRs or SNCRs as described above would be about 46.3%.

During 2012 and early 2013, PNM engaged in discussions with NMED and EPA regarding an alternative to the FIP and SIP. On February 15, 2013, PNM, NMED, and EPA agreed to pursue a revised plan that could provide a new BART path to comply with federal visibility rules at SJGS. The terms of the non-binding agreement would result in the retirement of SJGS Units 2 and

3 by the end of 2017 and the installation of SNCRs on Units 1 and 4 by the later of January 31, 2016 or 15 months after EPA approval of a revised SIP. Under this plan, NMED would develop a revised SIP and submit it to the EIB for approval. Upon approval by EIB, the revised SIP would be submitted to EPA for approval. EIB approval is projected for the fourth quarter of 2013, with EPA action in late 2014.

NMPRC approval of the retirement of SJGS Units 2 and 3 and plans for PNM to acquire power to replace its reduced capacity from SJGS would also be part of implementation. PNM also anticipates requesting approval to recover from ratepayers the unrecovered investment in SJGS Units 2 and 3 and costs incurred to retire those units. At March 31, 2013, PNM's net book value of SJGS Units 2 and 3 was approximately $290 million.

Contemporaneously with the signing of the non-binding agreement, EPA indicated in writing that if the terms agreed to do not move forward due to circumstances outside of the control of PNM and NMED, EPA will work with the state and PNM to create a reasonable FIP compliance schedule to reflect the time used to develop the new state plan. PNM is also exploring potential additional areas of relief, including relief from the Tenth Circuit.

In connection with the implementation of the plan, retirement of SJGS Units 2 and 3 could result in shifts in ownership among SJGS owners as may be agreed upon by the owners, including PNM acquiring additional ownership in SJGS Unit 4. Owners of the affected units also may seek approvals of their utility commissions or governing boards.

This plan primarily focuses on how SJGS would meet the regional haze rule, but also indicates that PNM would build a natural gas-fired generating plant to be sited at SJGS to partially replace the capacity from the retired coal units. Detailed replacement power strategies also would be finalized.  PNM believes adequate replacement power alternatives will be available to meet its generation needs and ensure reliability.

On February 25, 2013, the parties filed their status reports with the Tenth Circuit.  To demonstrate that progress has been made toward settling the Tenth Circuit litigation, information, including the non-binding agreement and its accompanying timeline, was submitted to the Tenth Circuit. Following the parties' submission of their status reports, on February 28, 2013, the Tenth Circuit referred the litigation to the Tenth Circuit Mediation Office, which has authority to require the parties to attend mediation conferences to informally resolve issues in the pending appeals.

On April 1, 2013, PNM submitted a new BART analysis to the NMED reflecting the terms of the non-binding agreement including the installation of SNCRs on Units 1 and 4 and the retirement of Units 2 and 3. NMED is currently preparing a new proposed SIP for BART.

If the February 15, 2013 plan described above is implemented, PNM currently estimates its share of the costs to install SNCRs and the additional equipment to comply with NAAQS requirements on SJGS Units 1 and 4 would be approximately $63 million, including gross receipts taxes, AFUDC, and other PNM costs. This amount is based on the anticipation that PNM's ownership share of SJGS Units 1 and 4 would aggregate to approximately 52%. PNM also estimates that the cost of replacing a portion of PNM's share of the reduction in generating capacity due to the retirement of SJGS Units 2 and 3 with identified gas-fired peaking capacity would be approximately $280 million. Neither of these amounts is included in PNM's current construction expenditure forecast since approval of the plan is subject to numerous conditions. Additional base load generating capacity may be required to replace a portion of retired SJGS capacity. Although the nature of additional base load capacity has not yet been identified, it could come from PVNGS Unit 3 or additional gas-fired generation. Operating costs would also increase with the installation of either SCRs or SNCRs.

PNM can provide no assurance that the requirements of the plan agreed to on February 15, 2013 will be accomplished at all or within the required timeframes. If the February 15, 2013 plan is not implemented, PNM would seek to work with NMED and EPA to develop a revised timetable for implementation of the FIP. If an agreement on a revised timetable cannot be reached, PNM will likely be unable to complete the installation of SCRs on all four units at SJGS by the FIP deadline of September 21, 2016. In such event, PNM would likely seek relief from the compliance deadline from EPA or the Tenth Circuit in order to continue to be able to operate the plant during the completion of the installation process. If relief is not granted, PNM could be forced to temporarily cease operation of some or all of the SJGS units. If a shutdown was required, PNM would then have to acquire temporary replacement power through short-term or open-market purchases in order to serve the needs of its customers. There can be no assurance that sufficient replacement power will be available to serve PNM's needs or, if available, what costs would be incurred.

PNM is unable to predict the ultimate outcome of these matters or what additional pollution control equipment will be required at SJGS.PNM will seek recovery from its ratepayers for all costs that may be incurred as a result of the CAA requirements. Although the additional equipment and other final requirements will result in additional capital and operating costs being incurred, PNM believes that its access to the capital markets is sufficient to be able to finance the installation. It is possible that requirements to comply with the CAA, combined with the financial impact of possible future climate change regulation or legislation, if any, other environmental regulations, the result of litigation, and other business considerations, could jeopardize the economic viability of SJGS or the ability of individual participants to continue participation in the plant.

Four Corners

On August 6, 2012, the EPA issued its final BART determination for Four Corners. The rule includes two compliance alternatives. The first emission control strategy finalized by the EPA would require the installation of post-combustion controls, including SCRs, on each of Units 1-5 at Four Corners to reduce NOx emissions. Under the second emission control alternative, the owners of Four Corners would have the option to close permanently Units 1-3 by January 1, 2014 and install SCR post-combustion NOx controls on each of Units 4 and 5 by July 31, 2018. For particulate matter emissions, EPA is requiring Units 4 and 5 to meet an emission limit of 0.015 lb/MMBTU and the plant to meet a 20% opacity limit, both of which are achievable through operation of the existing baghouses. Although unrelated to BART, the final BART rule also imposes a 20% opacity limitation on certain fugitive dust emissions from Four Corners' coal and material handling operations. The Four Corners participants have until July 1, 2013 to notify the EPA of which emission control strategy Four Corners will follow.

The Four Corners participants' obligations to comply with EPA's final BART determinations, coupled with the financial impact of possible future climate change regulation or legislation, other environmental regulations, and other business considerations, could jeopardize the economic viability of Four Corners or the ability of individual participants to continue their participation in Four Corners.

PNM is continuing to evaluate the impacts of EPA's BART determination for Four Corners. PNM estimates its share of costs, including PNM's AFUDC, to be up to approximately $75 million for post-combustion controls at Four Corners Units 4 and 5. PNM would seek recovery from its ratepayers of all costs that are ultimately incurred. PNM has no ownership interest in Four Corners Units 1, 2, and 3. PNM is unable to predict the ultimate outcome of this matter.

SCE, a participant in Four Corners, has indicated that certain California legislation may prohibit it from making emission control expenditures at Four Corners. APS and SCE entered into an asset purchase agreement, providing for the purchase by APS of SCE's 48% interest in each of Units 4 and 5 of Four Corners. The principal remaining condition to closing is the negotiation and execution of a new coal supply contract for Four Corners on terms reasonably acceptable to APS. See Coal Supply below. APS has announced that, if APS's purchase of SCE's interests in Units 4 and 5 at Four Corners is consummated, it will shutdown Units 1, 2, and 3 at the plant.

Four Corners BART FIP Challenge

On October 22, 2012, WEG filed a petition for review in the Ninth Circuit challenging the Four Corners BART FIP.  In its petition, WEG alleges that the final BART rule results in more air pollution being emitted into the air than allowed by law and that EPA failed to follow the requirements of the ESA.  APS intervened in this matter and filed a motion to dismiss this lawsuit for lack of jurisdiction or alternatively to transfer the lawsuit to the Tenth Circuit. On February 25, 2013, the Ninth Circuit denied APS' motion to dismiss, but granted the request to transfer the case to the Tenth Circuit. PNM cannot currently predict the outcome of this matter or the range of its potential impact.

Regional Haze Challenges

On December 27, 2012, WEG filed a petition for review in the Tenth Circuit challenging the SO₂ and particulate matter emissions elements of EPA's approval of New Mexico's Regional Haze SIP.  PNM intervened in this matter. PNM is continuing to evaluate the impacts of WEG's challenge to EPA's approval of this SIP.

On February 26, 2013, HEAL Utah and other environmental groups filed petitions in the Tenth Circuit challenging EPA's final approval of the remaining elements of New Mexico's Regional Haze SIP, as well as EPA's approval of the Albuquerque/Bernalillo County Air Quality Control Board SIP.  

PNM was granted intervention in both matters. On May 3, 2013, the Tenth Circuit ordered the parties to file consolidated briefing in the WEG and HEAL Utah matters due to the similarity of the WEG and HEAL Utah petitions.  PNM is unable to predict the ultimate outcome of these matters.

SJGS Operating Permit Challenge

On February 16, 2012, EPA issued its response to a WEG petition objecting to SJGS's operating permit granted by the NMED in January 2011. In its order, EPA required NMED to provide clarification on several of the matters raised by WEG.  EPA's order in this matter does not constitute a finding that the plant has violated any provision of the CAA or that it has violated any emission limits. 

In August 2012, NMED issued a response to the EPA order stating that SJGS's operating permit would be reopened to make certain modifications to the permit. NMED issued a public notice regarding proposed modifications to the SJGS operating permit on September 19, 2012 and issued a revised operating permit on November 26, 2012. The revised permit includes changes to the SO₂ and particulate matter emission limits that were previously incorporated into the SJGS NSR permit. In addition, the revised permit requires PNM to submit a compliance plan to address carbon monoxide (“CO”) emissions increases at SJGS Unit 2. The compliance plan must be submitted in May 2013 and requires that SJGS submit either a PSD permit application including BACT analysis for CO emissions from Unit 2 or a PSD avoidance permit application that limits net CO emissions increases below the CO PSD threshold of 100 tons per year. PNM is preparing a compliance plan, but does not believe it will have a material impact.

National Ambient Air Quality Standards (“NAAQS”)

The CAA requires EPA to set NAAQS for pollutants considered harmful to public health and the environment. EPA has set NAAQS for certain pollutants, including NOx, SO₂,ozone, and particulate matter. In 2010, EPA updated the primary NOx and SO₂ NAAQS to include a 1-hour maximum standard while retaining the annual standards for NOx and SO₂ and the 24-hour SO₂ standard. New Mexico is in attainment for the 1-hour NOx NAAQS. EPA has issued draft guidance on how to determine whether areas in a state comply with the new 1-hour SO₂ NAAQS and announced that it will publish further guidance or initiate rulemaking on these matters.  Although the determination process has not been finalized, PNM believes that compliance with the 1-hour SO₂ standard may require operational changes and/or equipment modifications at SJGS. On April 6, 2012, PNM filed an application for an amendment to its air permit for SJGS, which would be required for the installation of either SCRs or SNCRs described above. In addition, this application included a proposal by PNM to install equipment modifications for the purpose of reducing fugitive emissions, including NOx, SO₂, and particulate matter. These modifications would help SJGS meet the NAAQS. It is anticipated that this technology would be installed at the same time as the installation of regional haze BART controls, in order to most efficiently and cost effectively conduct construction activities at SJGS. The cost of this technology is dependent upon the type of control technology that is ultimately determined to be NOx BART at SJGS. See Regional Haze - SJGS above.

EPA finalized revisions to its NAAQS for fine particulate matter on December 14, 2012. PNM is currently evaluating the impact of the revised standard on SJGS and its operations.

In January 2010, EPA announced it would strengthen the 8-hour ozone standard by setting a new standard in a range of 0.060-0.070 parts per million. Work is underway to reconsider the ozone standard, with proposed revisions expected in the fall of 2013 and a final standard published by the end of 2014.  Depending upon where the standard for ozone is set, San Juan County, where SJGS is situated, could be designated as not attaining the standard for ozone. If that were to occur, NMED would have responsibility for bringing the county into compliance and would look at all sources of NOx and volatile organic compounds since these are the pollutants that form ground-level ozone. As a result, SJGS could be required to install further NOx controls to meet a new ozone NAAQS. In addition, other counties in New Mexico, including Bernalillo County, may be designated as non-attainment. PNM cannot predict the outcome of this matter, the impact of other potential environmental mitigations, or if additional NOx controls would be required as a result of ozone non-attainment designation.

Citizen Suit Under the Clean Air Act

The operations of SJGS are covered by a Consent Decree with the Grand Canyon Trust and Sierra Club and with the NMED that includes stipulated penalties for non-compliance with specified emissions limits. Stipulated penalty amounts are placed in escrow on a quarterly basis pending review of SJGS's emissions performance. In May 2011, PNM entered into an agreement with NMED and the plaintiffs to resolve a dispute over the applicable NOx emission limits under the Consent Decree. Under the agreement, so long as the NOx emissions limits imposed under the EPA FIP and the New Mexico SIP meet a specified emissions limit, and PNM does not challenge these limits, the parties' dispute is deemed settled.

In May 2010, PNM filed a petition with the federal district court seeking a judicial determination on a dispute relating to PNM's mercury controls. NMED and plaintiffs seek to require PNM to implement additional mercury controls. PNM estimates the implementation would increase annual mercury control costs for the entire station, which are currently $0.6 million, to a total of $6.1 million. The court appointed a special master to evaluate the technical arguments in the case and to address the detection and determination limits of the mercury monitors at SJGS and the appropriate brominated activated carbon injection rate that maximizes the reduction of mercury emissions from SJGS.  The special master issued a report indicating he was unable to make a determination on either of these issues.  In September 2012, PNM submitted objections to certain portions of the special master report and requested an evidentiary hearing. Also in September 2012, NMED and plaintiffs filed a motion asking the court to affirm certain findings in the special master report and order PNM to conduct additional mercury testing. PNM cannot predict the outcome of this matter.

Navajo Nation Environmental Issues

Four Corners is located on the Navajo Reservation and is held under an easement granted by the federal government, as well as a lease from the Navajo Nation. The Navajo Acts purport to give the Navajo Nation Environmental Protection Agency authority to promulgate regulations covering air quality, drinking water, and pesticide activities, including those activities that occur at Four Corners. In October 1995, the Four Corners participants filed a lawsuit in the District Court of the Navajo Nation challenging the applicability of the Navajo Acts to Four Corners. In May 2005, APS and the Navajo Nation signed an agreement resolving the dispute regarding the Navajo Nation's authority to adopt operating permit regulations under the Navajo Nation Air Pollution Prevention and Control Act. As a result of this agreement, APS sought, and the courts granted, dismissal of the pending litigation in the Navajo Nation Supreme Court and the Navajo Nation District Court, to the extent the claims relate to the CAA. The agreement does not address or resolve any dispute relating to other aspects of the Navajo Acts. The Company cannot currently predict the outcome of these matters or the range of their potential impacts.

Section 114 Request

In April 2009, APS received a request from EPA under Section 114 of the CAA seeking detailed information regarding projects at and operations of Four Corners. EPA has taken the position that many utilities have made physical or operational changes at their plants that should have triggered additional regulatory requirements under the NSR provisions of the CAA. APS has responded to EPA's request. PNM is currently unable to predict the timing or content of EPA's response, if any, or any resulting actions.

Four Corners Clean Air Act Lawsuit

In October 2011, Earthjustice, on behalf of several environmental organizations, filed a lawsuit in the United States District Court for the District of New Mexico against APS and the other Four Corners participants alleging violations of the NSR provisions of the CAA and NSPS violations. The plaintiffs seek to have the court enjoin operations at Four Corners until APS applies for and obtains any required NSR permits and complies with the NSPS. The plaintiffs further request the court to order the payment of civil penalties, including a beneficial mitigation project. The case is being held in abeyance while the parties seek to negotiate a settlement. On March 30, 2013, upon joint motion of the parties, the court issued an order deeming the motions to dismiss withdrawn without prejudice during pendency of the stay. At such time as the stay is lifted, the Four Corners participants may reinstate their motions to dismiss without risk of default. PNM cannot currently predict the outcome of this matter or the range of its potential impact.

Endangered Species Act

In January 2011, the Center for Biological Diversity, Diné Citizens Against Ruining Our Environment, and San Juan Citizens Alliance filed a lawsuit in the United States District Court for the District of Colorado against the OSM and the DOI, alleging that OSM failed to engage in mandatory ESA consultation with the United States Fish and Wildlife Service prior to authorizing the renewal of an operating permit for the mine that serves Four Corners.  The lawsuit alleges that activities at the mine, including mining and the disposal of coal combustion residue, will adversely affect several endangered species and their critical habitats.  The lawsuit requested the court to vacate and remand the mining permit and enjoin all activities carried out under the permit until OSM has complied with the ESA.  Neither PNM nor APS was a party to the lawsuit. On March 14, 2012, the Court entered an order dismissing the plaintiffs' lawsuit without prejudice. On May 14, 2012, the plaintiffs appealed the Court's order to the Tenth Circuit. PNM cannot currently predict the outcome of this matter or the range of its potential impact.

Cooling Water Intake Structures

EPA issued its proposed cooling water intake structures rule in April 2011, which would provide national standards for certain cooling water intake structures at existing power plants and other facilities under the Clean Water Act to protect fish and other aquatic organisms by minimizing impingement mortality (the capture of aquatic wildlife on intake structures or against screens) and entrainment mortality (the capture of fish or shellfish in water flow entering and passing through intake structures). The proposed rule would require facilities such as Four Corners and SJGS to either demonstrate that impingement mortality at its cooling water intakes does not exceed a specified rate or reduce the flow at those structures to less than a specified velocity and to take certain protective measures with respect to impinged fish. The proposed rule would also require these facilities to either meet the definition of a closed cycle recirculating cooling system or conduct a “structured site-specific analysis” to determine what site-specific controls, if any, should be required.

The proposed rule would require existing facilities to comply with the impingement mortality requirements as soon as possible, but no later than eight years after the effective date of the rule, and to comply with the entrainment requirements as soon as possible under a schedule of compliance established by the permitting authority. EPA is required to issue a final rule by June 27, 2013. PNM and APS continue to follow the rulemaking and are performing analyses to determine the potential costs of compliance with the proposed rule. PNM is unable to predict the outcome of this matter or a range of the potential costs of compliance.

Effluent Limitation Guidelines

On April 19, 2013, EPA proposed revised effluent limitation guidelines establishing technology-based wastewater discharge limitations for steam electric power plants.  EPA's proposal offers numerous options that target metals and other pollutants in wastewater streams originating from fly ash and bottom ash handling activities, scrubber activities, and non-chemical metal cleaning wastes operations.  EPA is subject to a consent decree deadline to finalize the revised guidelines by May 22, 2014. PNM is in the process of reviewing the pre-publication version of the rule to assess the impact to SJGS and Reeves Station, the only PNM-operated power plants that would be covered by the proposed rule. APS is currently assessing the impact to Four Corners. PNM is unable to predict the outcome of this matter or if it will have a material impact on PNM's financial position, results of operations, or cash flows. 

Santa Fe Generating Station

PNM and the NMED are parties to agreements under which PNM installed a remediation system to treat water from a City of Santa Fe municipal supply well, an extraction well, and monitoring wells to address gasoline contamination in the groundwater at the site of the former Santa Fe Generating Station and service center. PNM believes the observed groundwater contamination originated from off-site sources, but agreed to operate the remediation facilities until the groundwater meets applicable federal and state standards or until the NMED determines that additional remediation is not required, whichever is earlier. The municipal well continues to operate and meets federal drinking water standards. PNM is not able to assess the duration of this project.

The Superfund Oversight Section of the NMED has conducted multiple investigations into the chlorinated solvent plume in the vicinity of the site of the former Santa Fe Generating Station. In February 2008, a NMED site inspection report was submitted to EPA, which states that neither the source nor extent of contamination has been determined and also states that the source may

not be the former Santa Fe Generating Station. The NMED investigation is ongoing. In January 2013, NMED notified PNM that monitoring results from April 2012 showed elevated concentrations of nitrate in three monitoring wells and an increase in free-phase hydrocarbons in another well. None of these wells are routinely monitored as part of PNM's obligations under the settlement agreement. PNM is unable to predict the outcome of this matter, but does not believe the former generating station is the source of the nitrates or the increased levels of free-phase hydrocarbons.

Coal Combustion Byproducts Waste Disposal

CCBs consisting of fly ash, bottom ash, and gypsum from SJGS are currently disposed of in the surface mine pits adjacent to the plant. SJGS does not operate any CCB impoundments. The Mining and Minerals Division of the New Mexico Energy, Minerals and Natural Resources Department currently regulates mine placement of ash with federal oversight by the OSM. APS disposes of CCBs in ash ponds and dry storage areas at Four Corners and also sells a portion of its fly ash for beneficial uses, such as a constituent in concrete production.  Ash management at Four Corners is regulated by EPA and the New Mexico State Engineer's Office. 

In June 2010, EPA published a proposed rule that includes two options for waste designation of coal ash. One option is to regulate CCBs as a hazardous waste, which would allow EPA to create a comprehensive federal program for waste management and disposal of CCBs. The other option is to regulate CCBs as a non-hazardous waste, which would provide EPA with the authority to develop performance standards for waste management facilities handling the CCBs and would be enforced primarily by state authorities or through citizen suits. Both options allow for continued use of CCBs in beneficial applications. EPA's proposal does not address the placement of CCBs in surface mine pits for reclamation. An OSM CCB rulemaking team has been formed to develop a proposed rule. 

On April 5, 2012, several environmental groups, including Sierra Club, filed a citizen suit in the D.C. Circuit claiming that EPA has failed to review and revise RCRA's regulations with respect to CCBs. The groups allege that EPA has already determined that revisions to the CCBs regulations are necessary. They also claim that EPA now has a non-discretionary duty to revise the regulations. The environmental groups asked the court to direct EPA to complete its review of the regulation of CCBs and a hazardous waste analytical procedure and to issue necessary revisions of such regulations as soon as possible. Two industry group members subsequently filed separate lawsuits in the D.C. Circuit seeking to ensure that disposal of coal ash would not be regulated as a hazardous waste. The environmental and industry lawsuits have been consolidated.

PNM advocates for the non-hazardous regulation of CCBs. However, if CCBs are ultimately regulated as a hazardous waste, costs could increase significantly. PNM would seek recovery from its ratepayers of all costs that are ultimately incurred. PNM cannot predict the outcome of EPA's or OSM's proposed rulemaking regarding CCB regulation, including mine placement of CCBs, or whether these actions will have a material impact on its operations, financial position, or cash flows. 

Hazardous Air Pollutants (“HAPs”) Rulemaking

In December 2011, the EPA issued its final Mercury and Air Toxics Standards (“MATS”) to reduce emissions of heavy metals, including mercury, arsenic, chromium, and nickel, as well as acid gases, including hydrochloric and hydrofluoric gases, from coal and oil-fired electric generating units with a capacity of at least 25 MW. Existing facilities will generally have up to four years to demonstrate compliance with the new rule. PNM's assessment of MATS indicates that the control equipment currently used at SJGS allows the plant to meet the emission standards set forth in the rule although the plant may be required to install additional monitoring equipment. With regard to mercury, stack testing performed for EPA during the MATS rulemaking process showed that SJGS achieved a mercury removal rate of 99% or greater. APS will conduct testing to determine what additional controls, if any, will be required at Four Corners. If additional controls are required, the costs are not expected to be material.

Other Commitments and Contingencies

Coal Supply

The coal requirements for SJGS are being supplied by SJCC, a wholly owned subsidiary of BHP. In addition to coal delivered to meet the current needs of SJGS, PNM prepays SJCC for certain coal mined but not yet delivered to the plant site. At March 31, 2013 and December 31, 2012, prepayments for coal, which are included in other current assets, amounted to $14.1

million and $9.9 million. These amounts reflect delivery of a portion of the prepaid coal and its utilization due to the mine fire incident described below. SJCC holds certain federal, state, and private coal leases and has an underground coal sales agreement to supply processed coal for operation of SJGS through 2017. Under the coal sales agreement, SJCC is reimbursed for all costs for mining and delivering the coal, including an allocated portion of administrative costs, and receives a return on its investment. BHP Minerals International, Inc. has guaranteed the obligations of SJCC under the coal agreement. The coal agreement contemplates the delivery of coal that would supply substantially all the requirements of SJGS through December 31, 2017.

APS purchases all of Four Corners' coal requirements from a supplier that is also a subsidiary of BHP and has a long-term lease of coal reserves with the Navajo Nation. The Four Corners coal contract runs through July 6, 2016 with pricing determined using an escalating base-price. In December 2012, BHP announced that it has entered into a Memorandum of Understanding with the Navajo Nation setting out the key terms under which the coal mine would be sold to the Navajo Nation. The BHP subsidiary would be retained as the mine manager and operator until July 2016. Key terms of the new coal supply contract are being finalized by the Navajo Nation and the Four Corners owners. As a result of this proposed change in ownership, APS now expects that a new coal supply contract would be executed upon completion of negotiations and following the endorsement of the transfer of ownership to a new Navajo Nation commercial enterprise to be established by the Navajo Nation Tribal Council. On April 29, 2013, the Navajo Nation Tribal Council approved the creation of the new commercial enterprise with sufficient power and authority to execute the transaction with BHP. PNM is unable to predict the outcome of this matter.

In 2010, PNM updated its study of the final reclamation costs for both the surface mines that previously provided coal to SJGS and the current underground mine providing coal and revised its estimates of the final reclamation costs. The estimate for decommissioning the Four Corners mine was also revised in 2010. Based on the most recent estimates, remaining payments for mine reclamation, in future dollars, are estimated to be $59.9 million for the surface mines at both SJGS and Four Corners and $19.7 million for the underground mine at SJGS as of March 31, 2013. At March 31, 2013 and December 31, 2012, liabilities, in current dollars, of $25.9 million and $26.8 million for surface mine reclamation and $4.3 million and $4.2 million for underground mine reclamation were recorded in other deferred credits.

PNM collects a provision for surface and underground mine reclamation costs in its rates. The NMPRC has capped the amount that can be collected from ratepayers for final reclamation of the surface mines at $100.0 million. Previously, PNM recorded a regulatory asset for the $100.0 million and recovers the amortization of this regulatory asset in rates. If future estimates increase the liability for surface mine reclamation, the excess would be expensed at that time.

San Juan Underground Mine Fire Incident

On September 9, 2011, a fire was discovered at the underground mine owned and operated by SJCC that provides coal for SJGS. The federal Mine Safety and Health Administration (“MSHA”) was notified of the incident. On September 12, 2011, SJCC informed PNM that the fire was extinguished. However, MSHA required sealing the incident area and confirmation of a noncombustible environment before allowing re-entry of the sealed area. SJCC regained entry into the sealed area of the mine in early March 2012. On May 4, 2012, SJCC received approval from MSHA and resumed longwall mining operations. If further difficulties occur in the longwall mining operation, PNM and the other owners of SJGS would need to consider alternatives for operating SJGS, including running at less than full capacity or shutting down one or more units, the impacts of which cannot be determined at the current time.

The costs of the mine recovery flowed through the cost-reimbursable component of the coal supply agreement. PNM anticipates that it will recover through its FPPAC the portion of such costs allocable to its customers subject to New Mexico regulation. PNM's filings with the NMPRC reflect an estimate that this incident increased coal costs and the deferral of cost recovery under the FPPAC by $21.6 million. SJCC has submitted an insurance claim regarding the costs it incurred due to the mine fire. Any recovery obtained by SJCC through its insurance carrier may be reimbursable (in whole or in part) to PNM through the coal sales agreement. Any insurance recovery would be flowed through PNM's FPPAC to the extent it relates to increased coal costs included in the FPPAC. The potential impacts of any insurance settlement cannot be determined at the current time. Based on information PNM has received from SJCC to date, PNM does not expect the mine fire to have a material effect on its financial condition, results of operations, or cash flows.

Nuclear Fuel

The PVNGS participants are continually identifying their future nuclear fuel resource needs and negotiating arrangements to fill those needs. In late August 2012, one of PVNGS's suppliers that converts uranium concentrates to uranium hexafluoride invoked the force majeure provision in its contract when it shut down its conversion plant due to regulatory compliance issues. The PVNGS participants have sufficient strategic reserves of enriched uranium such that they do not anticipate a short-term impact on nuclear fuel supplies as a result of the force majeure declaration. The PVNGS participants are evaluating alternate long-term options for securing conversion services.

PVNGS Liability and Insurance Matters

Liability for incidents at nuclear power plants is governed by the Price-Anderson Act, which limits the liability of nuclear reactor owners to the amount of insurance available from both private sources and an industry retrospective payment plan. In accordance with the Price-Anderson Act, the PVNGS participants have insurance for public liability exposure for a nuclear incident totaling $12.6 billion per occurrence. Commercial insurance carriers provide $375 million and $12.2 billion is provided through a mandatory industry wide retrospective assessment program. If losses at any nuclear power plant covered by the program exceed the accumulated funds, PNM could be assessed retrospective premium adjustments. Based on PNM's 10.2% interest in each of the three PVNGS units, PNM's maximum potential assessment per incident for all three units is $36.0 million, with an annual payment limitation of $5.4 million.

The PVNGS participants maintain “all risk” (including nuclear hazards) insurance for damage to, and decontamination of, property at PVNGS in the aggregate amount of $2.75 billion, a substantial portion of which must first be applied to stabilization and decontamination. These coverages are provided by Nuclear Electric Insurance Limited (“NEIL”). Effective April 1, 2013, a sublimit of $1.5 billion for non-nuclear property damage losses has been enacted to the primary policy offered by NEIL. If NEIL's losses in any policy year exceed accumulated funds, PNM is subject to retrospective assessments of $4.3 million for each retrospective assessment declared by NEIL's Board of Directors. The insurance coverages discussed in this and the previous paragraph are subject to policy conditions and exclusions.

Water Supply

Because of New Mexico's arid climate and periodic drought conditions, there is concern in New Mexico about the use of water, including that used for power generation. PNM has secured groundwater rights in connection with the existing plants at Reeves Station, Delta, Afton, Luna, and Lordsburg. Water availability does not appear to be an issue for these plants at this time. However, prolonged drought, ESA activities and a Federal lawsuit by the State of Texas suing the State of New Mexico over water allocations could pose a threat of reduced water availability for these plants.

PNM, APS, and BHP have undertaken activities to secure additional water supplies for SJGS, Four Corners, and related mines to accommodate the possibility of inadequate precipitation in coming years. Since 2004, PNM has entered into agreements for voluntary sharing of the impacts of water shortages with tribes and other water users in the San Juan basin. This agreement has been extended through 2016. In addition, in the case of water shortage, PNM, APS, and BHP have reached agreement with the Jicarilla Apache Nation on a supplemental contract relating to water for SJGS and Four Corners that runs through 2016. Although the Company does not believe that its operations will be materially affected by drought conditions at this time, it cannot forecast the weather or its ramifications, or how policy, regulations, and legislation may impact the Company should water shortages occur in the future.

In April 2010, APS signed an agreement on behalf of the PVNGS participants with five cities to provide cooling water essential to power production at PVNGS for forty years.

PVNGS Water Supply Litigation

In 1986, an action commenced regarding the rights of APS and the other PVNGS participants to the use of groundwater and effluent at PVNGS. APS filed claims that dispute the court's jurisdiction over PVNGS' groundwater rights and their contractual rights to effluent relating to PVNGS and, alternatively, seek confirmation of those rights. In 1999, the Arizona Supreme Court issued a decision finding that certain groundwater rights may be available to the federal government and Indian tribes. In addition,

the Arizona Supreme Court issued a decision in 2000 affirming the lower court's criteria for resolving groundwater claims. Litigation on these issues has continued in the trial court. No trial dates have been set in these matters. PNM does not expect that this litigation will have a material impact on its results of operation, financial position, or cash flows.

San Juan River Adjudication

In 1975, the State of New Mexico filed an action in New Mexico District Court to adjudicate all water rights in the San Juan River Stream System, including water used at Four Corners and SJGS. PNM was made a defendant in the litigation in 1976. In March 2009, President Obama signed legislation confirming a 2005 settlement with the Navajo Nation. Under the terms of the settlement agreement, the Navajo water rights would be settled and finally determined by entry by the court of two proposed adjudication decrees.  The court has ordered that settlement of the Navajo Nation's claims under the settlement agreement and entry of the proposed decrees be heard in an expedited proceeding. 

PNM's water rights in the San Juan Basin may be affected by the rights recognized in the settlement agreement as being owned by the Navajo Nation, which comprise a significant portion of water available from sources on the San Juan River and in the San Juan Basin. Therefore, PNM has elected to participate in this proceeding.  The Company is unable to predict the ultimate outcome of this matter or estimate the amount or range of potential loss and cannot determine the effect, if any, of any water rights adjudication on the present arrangements for water at SJGS and Four Corners. Final resolution of the case cannot be expected for several years. An agreement reached with the Navajo Nation in 1985, however, provides that if Four Corners loses a portion of its rights in the adjudication, the Navajo Nation will provide, for an agreed upon cost, sufficient water from its allocation to offset the loss.

Complaint Against Southwestern Public Service Company

In September 2005, PNM filed a complaint under the Federal Power Act against SPS alleging SPS overcharged PNM for deliveries of energy through its fuel cost adjustment clause practices. PNM also intervened in a proceeding brought by other customers raising similar arguments relating to SPS' fuel cost adjustment clause practices (the “Golden Spread proceeding”). In 2008, FERC issued its order in the Golden Spread proceeding affirming that SPS violated its fuel cost adjustment clause tariffs, but shortening the refund period applicable to the violation of the fuel cost adjustment clause issues. PNM and SPS have filed petitions for rehearing and clarification of the scope of the remedies that were ordered and reversal of various rulings in the order. FERC has not yet acted upon the requests for rehearing or clarification and they remain pending further decision. PNM cannot predict the final outcome of the case at FERC or the range of possible outcomes.

Navajo Nation Allottee Matters

A putative class action was filed against PNM and other utilities in February 2009 in the United States District Court in Albuquerque. Plaintiffs claim to be allottees, members of the Navajo Nation, who pursuant to the Dawes Act of 1887, were allotted ownership in land carved out of the Navajo Nation and allege that defendants, including PNM, are rights-of-way grantees with rights-of-way across the allotted lands and are either in trespass or have paid insufficient fees for the grant of rights-of-way or both.  In March 2010, the court ordered that the entirety of the plaintiffs' case be dismissed. The court did not grant plaintiffs leave to amend their complaint, finding that they instead must pursue and exhaust their administrative remedies before seeking redress in federal court.  In May 2010, plaintiffs filed a Notice of Appeal with the Bureau of Indian Affairs ("BIA"), which was denied by the BIA Regional Director. In May 2011, plaintiffs appealed the Regional Director's decision to the DOI Board of Appeals. Briefings on the merits of the appeal are complete and a decision is pending. PNM is participating in order to preserve its interests regarding any PNM-acquired rights-of-way implicated in the appeal. PNM cannot predict the outcome of the proceeding or the range of potential outcomes at this time.

In a separate matter, in September 2012, forty-three landowners claiming to be Navajo allotees filed a notice of appeal with the BIA appealing a March 2011 decision of the BIA Regional Director regarding renewal of a right-of-way for a PNM transmission line. The allotees, many of whom are also allottees in the above matter, generally allege that they were not paid fair market value for the right-of-way, that they were denied the opportunity to make a showing as to their view of fair market value, and thus denied due process. PNM is participating in this matter in order to preserve its interests regarding the right-of-way implicated in the appeal. PNM cannot predict the outcome of the proceeding or the range of potential outcomes at this time.

TGP Complaint

On March 2, 2012, TGP Granada, LLC and its affiliate (collectively, “TGP”) filed a complaint at FERC against PNM and Tortoise Capital Resources Corp. (“TTO”). PNM owns 60% of the EIP and leases the other 40% from TTO. PNM's lease of the portion of the EIP owned by TTO expires on April 1, 2015. The lease provides PNM the option, with 24 months advance notice, of purchasing the leased assets at the end of the lease for fair market value, as well as options to renew the lease.

TGP's filing requested FERC to direct PNM and TTO to identify the party that will immediately assume the obligation of making transmission capacity on the EIP available to customers for use after the April 1, 2015 expiration of the EIP lease agreement. TGP also requested a declaratory order or waiver regarding certain provisions of PNM's Open Access Transmission Tariff to allow its affiliate to change the point-of-receipt associated with a transmission service agreement related to the EIP without losing its transmission service priority. On July 5, 2012, FERC issued an order denying TGP's requests for declaratory order and waiver. In addition, FERC directed PNM, in consultation with TTO, to identify the party that will provide long-term transmission service over the leased portion of the EIP.

On November 1, 2012, PNM and TTO entered into a definitive agreement for PNM to exercise the option to purchase on April 1, 2015 the leased capacity at fair market value, which the parties agreed would be $7.7 million. The lease remains in existence and PNM will record the purchase at the termination of the lease on April 1, 2015. The definitive agreement sets forth the terms and conditions under which PNM would also assume responsibility for scheduling long-term transmission service on the leased capacity. In November 2012, PNM requested the necessary FERC approvals for the definitive agreement. In January 2013, FERC approved PNM's requests. On February 8, 2013, FERC issued an order dismissing as moot a motion filed by TGP for clarification of FERC's July 5, 2012 order. Since no rehearing request or appeal was filed, the February 8, 2013 order is final and non-appealable.

(10) Regulatory and Rate Matters

The Company is involved in various regulatory matters, some of which contain contingencies that are subject to the same uncertainties as those described in Note 9. Additional information concerning regulatory and rate matters is contained in Note 17 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

PNM

Renewable Portfolio Standard

The REA establishes a mandatory RPS requiring a utility to acquire a renewable energy portfolio equal to 10% of retail electric sales by 2011, 15% by 2015, and 20% by 2020. The NMPRC requires renewable energy portfolios to be “fully diversified.” Prior to December 2012, the diversity requirements were 20% from wind energy, 20% from solar energy, 10% from other renewable technologies, and 1.5% from distributed generation with the distributed generation component increasing to 3% in 2015. In December 2012, NMPRC issued an order that amended the diversity requirements to 30% wind, 20% solar, 5% other, and 1.5% distributed generation, increasing to 3% in 2015, and adopted other changes to its renewable energy rule, including the increase in the RCT discussed below.

The REA provides for streamlined proceedings for approval of utilities' renewable energy procurement plans, assures utilities recovery of costs incurred consistent with approved procurement plans, and requires the NMPRC to establish a RCT for the procurement of renewable resources to prevent excessive costs being added to rates. The NMPRC had established a RCT for 2011 of 2% of all customers' aggregated overall annual electric charges that increased by 0.25% annually until reaching 3% in 2015. In December 2012, the NMPRC approved an amended RCT set at 3% of customers' annual electric charges beginning in 2013 and continuing thereafter.

In July 2011, PNM filed its renewable energy procurement plan for 2012. The plan requested a variance from the RPS due to RCT limitations. The plan was diversity-compliant based on the reduced RPS, except for non-wind/non-solar resources, which were not available. In December 2011, the NMPRC approved PNM's 2012 plan, but ordered PNM to spend an additional $0.9 million on renewable procurements in 2012. PNM intends to recover the costs of the supplemental procurements through the renewable rider discussed below. The NMPRC also required PNM to file its 2013 renewable energy procurement plan by April

30, 2012. The 2013 plan proposed procurements for 2013 and 2014 of 20 MW of PNM-owned solar PV facilities, at an estimated cost of $45.5 million, wind and solar REC purchases in 2013, and a PPA for the output of a new geothermal facility. The plan also included an additional procurement of 2 MW of PNM-owned solar PV facilities at an estimated cost of $4.5 million to supply the energy sold under PNM's voluntary renewable energy tariff. The plan will enable PNM to comply with the statutory RPS amount in 2013, but requires a variance from the NMPRC's diversity requirements in 2013 while the proposed geothermal facilities are being constructed. This plan had been expected to achieve full RPS quantity and diversity compliance by 2014 without exceeding the RCT. The NMPRC approved the plan in December 2012, but reduced the additional solar PV procurement from 2 MW to 1.5 MW. Construction of the geothermal facility has been delayed due to a longer than expected permitting process. This will delay the in-service date of the geothermal facility until later in 2014. PNM does not believe this delay will affect its ability to comply with the diversity requirements as amended in December 2012.

PNM is recovering certain renewable procurement costs from customers through a rate rider. See Renewable Energy Riderbelow.

Renewable Energy Rider

On August 14, 2012, the NMPRC authorized PNM to recover certain renewable procurement costs through a rate rider on a per KWh basis. The approved rates are $0.0022335 per KWh in 2012 and $0.0028371 per KWh in 2013. The order disapproved the recovery of the cost of a supplemental REC procurement ordered by the NMPRC in the 2012 procurement plan case because the NMPRC had not yet acted on the specific $0.9 million procurement proposed by PNM, which is discussed under Renewable Portfolio Standard above. The NMPRC subsequently approved the supplemental REC procurement, but ordered that a hearing be held on its inclusion in the rider. PNM implemented the rider on August 20, 2012. The rider will terminate upon a final order in PNM's next general rate case unless the NMPRC authorizes PNM to continue it. Amounts collected under the rider are capped at $18.0 million in 2012 and $24.6 million in 2013. Any amounts above the caps are deferred for future recovery without carrying costs. As a separate component of the rider, if PNM's earned return on jurisdictional equity in 2013, adjusted for weather and other items not representative of normal operations, exceeds 10.5%, PNM must refund to customers during May through December 2014 the amount over 10.5%.

In compliance with the NMPRC's  rate rider order, PNM filed a notice to implement a 3.37% increase in the current rider rate effective with May 2013 bills.  The NMPRC suspended the effective date of the new rate for a period of nine months from April 1, 2013 and appointed a Hearing Examiner to conduct a hearing on the proposed change.  The Hearing Examiner recommended approval of the notice. On April 24, 2013, the NMPRC issued an order denying approval of the Hearing Examiner's Recommended Decision but did not disapprove the notice. The costs proposed to be recovered have been previously approved for recovery by the NMPRC. The order did not rescind these prior approvals. The order does not indicate what further proceedings, if any, the NMPRC intends to conduct.  On May 3, 2013, PNM, the NMPRC staff, and an intervening party filed a joint motion  for rehearing of the NMPRC order.

Energy Efficiency and Load Management

Program Costs

Public utilities are required by the Efficient Use of Energy Act to achieve specified levels of energy savings and to obtain NMPRC approval to implement energy efficiency and load management programs. Costs to implement approved programs are recovered through a rate rider. In 2013, this act was amended to set an annual program budget equal to 3% of a utility's annual revenue.

In October 2012, PNM filed an energy efficiency program application for programs to be offered beginning in May 2013. The filing included proposed program costs of $22.5 million plus a proposed profit incentive of $4.2 million and requested that the NMPRC issue an order by April 1, 2013. Portions of the program plan and proposed profit incentive are opposed by other parties to the case. PNM subsequently revised its proposed profit incentive to $2.9 million. A hearing on the application was held in February 2013. PNM is not able to predict the outcome of this matter.

Disincentives/Incentives Adder

The Efficient Use of Energy Act requires the NMPRC to remove utility disincentives to implementing energy efficiency and load management programs and to provide incentives for such programs. A rule approved by the NMPRC authorized electric utilities to collect rate adders of $0.01 per KWh for lifetime energy savings and $10 per KW for demand savings related to energy efficiency and demand response programs beginning in 2010. The NMAG and NMIEC appealed the NMPRC order adopting this rule to the New Mexico Supreme Court. PNM began implementing a rate rider under the rule to collect adders related to its 2010 program savings in December 2010 while the appeal of the rule was pending. In July 2011, the Supreme Court annulled and vacated the order adopting the rule and remanded the matter to the NMPRC. As a result of the Supreme Court decision, PNM filed revised tariffs and ceased collecting this adder for 2010 program savings on August 21, 2011. Of the $4.2 million authorized for recovery, $2.6 million was collected through August 20, 2011.

In June 2011, prior to the Supreme Court decision, the NMPRC approved PNM-specific adders of $0.002 per KWh and $4 per KW for savings due to programs implemented in 2011. PNM is presently collecting $1.3 million in adder revenues consistent with this order. After the Supreme Court decision vacating the rule, the NMPRC initiated a proceeding to determine whether PNM should be required to cease collecting the adders and to refund all adder revenues collected since December 2010. In November 2011, the NMPRC issued orders that PNM is not required to refund any adder revenues and is authorized to continue collecting the adders. However, in an order on rehearing, which it subsequently rescinded, the NMPRC further reduced the amount of the authorized adders. Prior to the rescission, PNM appealed the rehearing order to the Supreme Court. In March 2012, the Supreme Court granted PNM's motion to vacate the rehearing order and dismiss PNM's appeal. In a separate appeal and writ proceeding in the Supreme Court, NMIEC and the NMAG seek to overturn the NMPRC order allowing PNM to continue to collect adders in light of the 2011 Supreme Court decision. On May 21, 2012 the Supreme Court dismissed the writ proceeding. Oral argument in the appeal was held in December 2012, and a decision in the appeal is expected in 2013. PNM is unable to predict the outcome of the appeal.

On March 27, 2013, PNM filed the reconciliation for actual energy efficiency program costs, associated incentives, and actual collections for calendar year 2012. The reconciliation filing showed a net over-recovery of $0.2 million, composed of an over-recovery of $1.0 million of program costs and an under-recovery of incentives of $0.8 million. PNM subsequently revised the estimated incentive under-recovery to $0.5 million. PNM and the NMPRC staff filed a motion seeking to substitute the new reconciliation filing with a proposed effective date of May 28, 2013. On April 24, 2013, the NMPRC issued an order granting the motion. Under the order, the new rate based on the adjusted reconciliation amount will become effective on May 28, 2013, unless suspended by the NMPRC.

Decoupling Rulemaking

On May 15, 2012, the NMPRC issued a NOPR that would have amended the NMPRC's energy efficiency rule to authorize use of a decoupling mechanism to recover certain fixed costs of providing retail electric service from the rates charged on a per KWh of consumption, as the mechanism for removal of disincentives associated with the implementation of energy efficiency programs. The proposed rule also addressed incentives associated with energy efficiency. On July 26, 2012, the NMPRC closed the proposed rulemaking and opened a new energy efficiency rulemaking docket that may address decoupling and incentives. Workshops to develop a proposed rule have been held, but no order proposing a rule has been issued. PNM is unable to predict the outcome of this matter.

2010 Electric Rate Case and FPPAC

An order of the NMPRC approving an amended stipulation in PNM's 2010 Electric Rate Case limits the amount that can be recovered on an annual basis for fuel costs, renewable energy costs, and energy efficiency costs during certain years. Costs in excess of the limits are deferred, without carrying costs, for recovery in future periods. The fuel cost caps are $38.8 million for the FPPAC year beginning July 1, 2012, which PNM began collecting at that time, and $36.2 million for the FPPAC year beginning July 1, 2013. PNM estimates that the caps will result in approximately $45.5 million of FPPAC costs being deferred for future collection at June 30, 2014. Costs attributed to the mine fire incident discussed in Note 9 are included in the FPPAC amounts. Possible recovery of costs through SJCC's insurance, also discussed in Note 9, is not reflected in the FPPAC amounts.

PNM must file an application for continued use of its FPPAC every four years. PNM anticipates making this continuation filing in May 2013.

2011 Integrated Resource Plan

NMPRC rules require that investor owned utilities file an IRP every three years. The IRP is required to cover a 20-year planning period and contain an action plan covering the first four years of that period. In its most recent IRP, which was filed in July 2011, PNM indicated that it planned to meet its anticipated load growth through a combination of new natural gas-fired generating plants, renewable energy resources, load management, and energy efficiency programs. However, PNM has not entered into any commitments regarding these plans beyond what is otherwise described herein. As required by NMPRC rules, PNM utilized a public advisory group process during the development of the 2011 IRP. Two protests were filed to the IRP requesting rejection of the plan. The NMPRC assigned the case to a Hearing Examiner and designated a mediator to facilitate negotiations. The NMPRC staff filed a motion in December 2011 to dismiss the protests and terminate the proceeding on the ground that PNM's IRP fully complies with NMPRC rules. PNM is unable to predict the outcome of this matter.

Emergency FPPAC

In 2008, the NMPRC authorized PNM to implement an Emergency FPPAC from June 2, 2008 through June 30, 2009. The NMPRC order approving the Emergency FPPAC also provided that if PNM's base load generating units did not operate at or above a specified capacity factor and PNM was required to obtain replacement power to serve jurisdictional customers, PNM would be required to make a filing with the NMPRC seeking approval of the replacement power costs. In its required filing, PNM stated that the costs of the replacement power amounting to $8.0 million were prudently incurred and made a motion that they be approved. The NMPRC staff opposed PNM's motion and recommended that PNM be required to refund the amount collected. Auditors selected by the NMPRC found that PNM was prudent in operating its base load units and in securing replacement power but had not obtained prior NMPRC approval in the manner required by the NMPRC order. PNM continues to assert that its recovery of replacement power costs was proper and did not violate the NMPRC's order. The NMPRC has not ruled on this matter. Under the terms of the approved stipulation in the 2010 Electric Rate Case, the parties to the stipulation, including the NMPRC staff, jointly requested that the NMPRC take no further action in this matter and close the docket. No party has opposed that request. Although the NMPRC has not acted on the joint request, the NMPRC electronic docket shows the docket closed. PNM is unable to predict the outcome of this matter.

Applications for Approvals to Purchase Delta

As discussed in Note 9 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K, PNM has entered in to an agreement to purchase Delta, a 132 MW natural gas peaking unit from which PNM currently acquires energy and capacity under a PPA. The agreement to purchase Delta is subject to approvals by the NMPRC and FERC. On January 3, 2013, PNM filed an application with the NMPRC for a Certificate of Convenience and Necessity to own and operate Delta and for a determination of related ratemaking principles and treatment. PNM requested expedited consideration of the application so that a final order could be issued by May 31, 2013. The NMPRC has assigned the matter to a hearing examiner. A hearing on the application is scheduled to begin on May 13, 2013. PNM filed an application for approval of the Delta acquisition at FERC on January 24, 2013. FERC approved the purchase on February 26, 2013. PNM is unable to predict the outcome of this matter.

Application for Approval of La Luz Generating Station

PNM anticipates filing an application for a Certificate of Convenience and Necessity for a new 40 MW gas-fired generating facility near Belen, New Mexico with the NMPRC in May 2013. The application also will ask for a determination of related ratemaking principles and treatment. The estimated cost of this facility is approximately $63.2 million. PNM anticipates an in-service date in the first quarter of 2016. PNM has entered into a contract for the turbine to be used for this project. PNM also has entered into a turn-key contract with an outside contractor for the construction of the generating facility. Both of these contracts allow PNM to cancel the project if NMPRC approval is not obtained. PNM is unable to predict the outcome of this matter.

Transmission Rate Case

In October 2010, PNM filed a notice with FERC to increase its wholesale electric transmission revenues by $11.1 million annually, based on a return on equity of 12.25%. The filing also sought to revise certain Open Access Transmission Tariff provisions and bi-lateral contractual terms.  In December 2010, FERC issued an order accepting PNM's filing and suspending the proposed tariff revisions for five months. The proposed rates were implemented on June 1, 2011, subject to refund. The rate increase applied to all of PNM's wholesale electric transmission service customers, which include other utilities, electric cooperatives, and entities that use PNM's transmission system to transmit power at the wholesale level.  The rate increase did not impact PNM's retail

customers. On January 2, 2013, FERC approved an unopposed settlement agreement, which increases transmission service revenues by $2.9 million annually. In addition, the parties agreed that if PNM files for a formula based rate change within one year from FERC's approval of the settlement agreement, no party will oppose the general principle of a formula rate, although the parties may still object to particular aspects of the formula. PNM refunded amounts collected in excess of the settled rates in January 2013. See Tri-State Complaint below.

Formula Transmission Rate Case

On December 31, 2012, PNM filed an application with FERC for authorization to move from charging stated rates for wholesale electric transmission service to a formula rate mechanism pursuant to which rates for wholesale transmission service are calculated annually in accordance with an approved formula. The proposed formula includes updating cost of service components, including investment in plant and operating expenses, based on information contained in PNM's annual financial report filed with FERC, as well as including projected large transmission capital projects to be placed into service in the following year. The projections included are subject to true-up in the following year formula rate. Certain items, including changes to return on equity and depreciation rates, require a separate filing to be made with FERC before being included in the formula rate. The rates resulting from PNM's application are intended to replace the rates approved by the FERC on January 2, 2013 in the transmission rate case discussed above. As filed, PNM's request would result in a $3.2 million wholesale electric transmission rate increase, based on PNM's 2011 data and a 10.81% return on equity, and authority to adjust transmission rates annually based on an approved formula. The proposed $3.2 million rate increase would be in addition to the $2.9 million rate increase approved by the FERC on January 2, 2013 in the transmission rate case discussed above.

On March 1, 2013, FERC issued an order (1) accepting PNM's revisions to its rates for filing and suspending the proposed revisions to become effective August 2, 2013, subject to refund; (2) directing PNM to submit a compliance filing to establish its return-on-equity (“ROE”) using the median, rather than the mid-point, of the ROEs from a proxy group of companies; (3) directing PNM to submit a compliance filing to remove the acquisition adjustment related to PNM's 60% ownership of the EIP transmission line from its rate proposal; and (4) setting the proceeding for hearing and settlement judge procedures. PNM would be allowed to make a separate filing related to recovery of the EIP acquisition adjustment. On April 1, 2013, PNM made the required compliance filing. In addition, PNM filed for rehearing of FERC's order regarding the ROE. On May 1, 2013, PNM provided an updated rate request to its wholesale electric transmission service customers incorporating 2012 data and the FERC order into the formula rate. The updated formula rate would result in a $1.3 million rate increase over the rates approved by FERC on January 2, 2013. PNM anticipates filing the updated rate request with FERC on June 1, 2013. The new rates will apply to all of PNM's wholesale electric transmission service customers, which include other utilities, electric cooperatives, and entities that use PNM's transmission system to transmit power at the wholesale level. The new rates will not apply to PNM's retail customers. PNM is unable to predict the outcome of this proceeding.

Tri-State Complaint

On March 13, 2013, Tri-State filed a complaint with FERC alleging that PNM's existing transmission rates approved by FERC on January 2, 2013 in the transmission rate case discussed above are unjust and unreasonable under the Federal Power Act.  Tri-State's allegations are premised upon FERC's March 1, 2013 order and certain data provided by PNM in PNM's Formula Transmission Rate Case discussed above.  Tri-State seeks a reduction in PNM's annual transmission revenue requirement for the period between March 13, 2013 and the implementation of PNM's proposed rates under the Formula Transmission Rate Case.  Tri-State also requests that FERC consolidate the complaint proceeding with the Formula Transmission Rate Case.  On April 2, 2013, PNM answered Tri-State's complaint, asking FERC to dismiss the complaint and deny Tri-State's request to consolidate the complaint proceeding with the Formula Transmission Rate Case. PNM is unable to predict the outcome of this proceeding.

Firm-Requirements Wholesale Customers

Navopache Electric Cooperative, Inc. Rate Case

In September 2011, PNM filed an unexecuted amended sales agreement between PNM and NEC with FERC. The agreement proposed a cost of service based rate for the electric service and ancillary services PNM provides to NEC, which would result in an annual increase of $8.7 million or a 39.8% increase over existing rates. PNM also requested a FPPAC and full recovery of certain third-party transmission charges PNM incurs to serve NEC. NEC filed a protest to PNM's filing with FERC. In November

2011, FERC issued an order accepting the filing, suspending the effective date to be effective April 14, 2012, subject to refund, and set the proceeding for settlement. The parties finalized a settlement agreement and PNM filed for the necessary FERC approval on December 6, 2012. The settlement agreement would result in an annual increase of $5.3 million, an extension of the contract for 10 years, and an agreement that PNM will be able to file an application for formula based rates to be effective in 2015. On April 5, 2013, FERC approved the settlement agreement. PNM anticipates refunding amounts collected in excess of the settled rates by June 4, 2013.

City of Gallup, New Mexico Contract Approval Case

PNM provides both energy and power services to Gallup, PNM's second largest firm-requirements wholesale customer, under an electric service agreement that expires June 30, 2013. On May 1, 2013, PNM and Gallup agreed to extend the term of the agreement to June 30, 2014 and to increase the demand and energy rates under the agreement. On May 1, 2013, PNM requested FERC approval of the amended agreement to be effective July 1, 2013. If approved by FERC, revenue from Gallup would increase by $3.1 million during the term of the amended agreement. PNM is unable to predict the outcome of this proceeding.

TNMP

Advanced Meter System Deployment and Surcharge Request

In July 2011, the PUCT approved a settlement and authorized an AMS deployment plan that permits TNMP to collect $113.3 million in deployment costs through a surcharge over a 12-year period. TNMP began collecting the surcharge on August 11, 2011. Deployment of advanced meters began in September 2011 and is scheduled to be completed over a 5-year period. In February 2012, the PUCT opened a proceeding to consider the feasibility of an “opt-out” program for retail consumers that wish to decline receipt of an advanced meter. The PUCT has requested comments and convened a public meeting to hear various issues. No proposal or decision has yet been announced by the PUCT. However, various individuals filed a petition with the PUCT seeking a moratorium on any advanced meter deployment. The PUCT denied the petition and an appeal was filed with the Texas District Court on September 28, 2012. On February 21, 2013, the PUCT filed a proposed rule to permit customers to opt-out of the AMS deployment. A hearing to receive additional comment on the proposed rulemaking was held on April 19, 2013. Any opt-out program would apply to all transmission and distribution utilities in ERCOT. TNMP cannot predict the outcome or effect of this proceeding.

Energy Efficiency

TNMP recovers the costs of its energy efficiency programs through an energy efficiency cost recovery factor. On August 28, 2012, the PUCT approved a settlement that permits TNMP to collect estimated 2013 program costs of $4.8 million, plus recovery of an aggregate of $0.4 million in under-collected costs from prior years, case expenses, and a performance bonus for 2011. TNMP's new rates were effective January 1, 2013. TNMP anticipates filing by June 1, 2013 to collect estimated 2014 energy efficiency program costs of $4.7 million and a $0.7 million bonus for 2012.

Transmission Cost of Service Rates

TNMP can update its transmission rates twice per year to reflect changes in its invested capital. Updated rates reflect the addition and retirement of transmission facilities, including appropriate depreciation, federal income tax and other associated taxes, and the approved rate of return on such facilities.

On August 23, 2012, TNMP filed an application to update its transmission rates to reflect changes in its invested capital. The application reflected an increase in total rate base of $26.4 million and requested an increase in revenues of $2.5 million annually. The PUCT approved the interim adjustment and TNMP implemented it on September 27, 2012.

On January 31, 2013, TNMP filed an application to further update its transmission rates to reflect changes in its invested capital. The requested increase in total rate base is $21.9 million, which will increase revenues $2.9 million annually. On March 19, 2013, the PUCT ALJ approved TNMP's interim transmission cost of service filing and rates went into effect with bills rendered March 20, 2013.

(12) Income Taxes

As required under GAAP, the Company makes an estimate of its anticipated effective tax rate for the year as of the end of each quarterly period within its fiscal year. Year-to-date income tax expense is then calculated by applying the anticipated annual effective tax rate to year-to-date earnings before taxes, which includes the earnings attributable to the Valencia non-controlling interest. GAAP also provides that certain unusual or infrequently occurring items, as well as adjustments due to enactment of new tax laws, be excluded from the estimated annual effective tax rate calculation.

On January 3, 2013, the American Taxpayer Relief Act of 2012, which extended fifty percent bonus depreciation, was signed into law.  Due to provisions in the act, taxes payable to the State of New Mexico for 2013 were reduced, which results in an impairment of New Mexico wind energy production tax credits. In accordance with GAAP, PNMR was required to record this impairment, which after federal income tax benefit amounted to $1.5 million, as additional income tax expense during the three months ended March 31, 2013. This impairment is reflected in PNMR's Corporate and Other segment.

On April 30,2013, the IRS issued Revenue Procedure 2013-24, which provides a safe harbor method of accounting that taxpayers may use to determine repair costs for electric generation property.  Adoption of the safe harbor method is elective for years ending on or after December 31, 2012.  The Company is evaluating the possible effects of adopting the safe harbor method and the ultimate outcome cannot be determined at this time.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management's Discussion and Analysis of Financial Condition and Results of Operations for PNMR is presented on a combined basis, including certain information applicable to PNM and TNMP. The MD&A for PNM and TNMP is presented as permitted by Form 10-Q General Instruction H (2). This report uses the term “Company” when discussing matters of common applicability to PNMR, PNM, and TNMP. A reference to a “Note” in this Item 2 refers to the accompanying Notes to Condensed Consolidated Financial Statements (Unaudited) included in Item 1, unless otherwise specified. Certain of the tables below may not appear visually accurate due to rounding.

MD&A FOR PNMR

EXECUTIVE SUMMARY

Overview and Strategy

PNMR is a holding company with two regulated utilities serving approximately 741,000 residential, commercial, and industrial customers and end-users of electricity in New Mexico and Texas.

Strategic Goals

PNMR is focused on achieving the following strategic goals:

• Earning authorized returns on its regulated businesses

• Continuing to improve credit ratings

• Providing a top-quartile total return to investors

In conjunction with these goals, PNM and TNMP are dedicated to:

• Achieving industry-leading safety performance and customer satisfaction

• Maintaining strong plant performance and reliability

Earning Authorized Returns on Regulated Businesses

PNMR's success in accomplishing its strategic goals is highly dependent on continued favorable regulatory treatment for its utilities. The Company has multiple strategies to achieve favorable regulatory treatment, all of which have as their foundation a focus on the basics: managing the Company's business and serving our customers well, while engaging stakeholders to build productive relationships.

Both PNM and TNMP seek cost recovery for their investments through general rate cases and various rate riders. The PUCT has approved mechanisms that allow for recovery of capital invested in transmission and distribution projects without having to file a general rate case and allow for more timely recovery of amounts invested in TNMP's systems. In 2011 and 2012, PNM made significant progress toward the goal of achieving authorized returns for its retail customers. In 2012, PNM saw additional progress toward achieving authorized returns for its transmission and generation customers regulated by FERC. PNM and TNMP completed several rate proceedings before their state regulators in 2011, 2012, and early 2013. Additional information about rate filings is provided in Note 17 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K and in Note 10.

Fair and timely rate treatment from regulators is crucial to achieving PNMR's strategic goals because it leads to PNM and TNMP earning their allowed returns. PNMR believes that if the utilities earn their allowed returns, it would be viewed positively by rating agencies and would further improve credit ratings, which could lower costs to customers. Also, earning allowed returns should result in increased earnings for PNMR, which should lead to increased total returns to investors.

PNM's interest in PVNGS Unit 3 is excluded from NMPRC jurisdictional rates. While PVNGS Unit 3's financial contribution is not calculated in the authorized returns on its regulated business, it impacts PNM's earnings and has demonstrated to be a valuable asset. Power generated from PNM's 134 MW interest in PVNGS Unit 3 is currently sold into the wholesale market and any earnings or losses are attributable to shareholders.

63

Continuing to Improve Credit Ratings

PNM is committed to maintaining investment grade credit ratings. The credit ratings for PNMR, PNM, and TNMP were set forth under the heading Liquidity in the MD&A contained in the 2012 Annual Reports on Form 10-K. As discussed under the subheading Liquidity in MD&A below, S&P raised the corporate credit ratings and senior debt ratings for PNMR, PNM, and TNMP, as well as the preferred stock rating for PNM, on April 5, 2013. S&P retained the outlook as stable for all entities.

Providing Top-Quartile Total Returns to Investors

PNMR's strategic goal to provide top quartile total return to investors is based on five-year ongoing EPS growth along with five-year average dividend yield. Top quartile total return currently is equal to an average annual rate of 10 percent to 13 percent.     PNMR's long-term target is a dividend payout ratio of 50 percent to 60 percent of its ongoing earnings. Ongoing earnings, which is a non-GAAP financial measure, excludes certain non-recurring, infrequent, and other items from earnings determined in accordance with GAAP. The annual common stock dividend was raised by 16 percent in February 2012 and 14 percent in February 2013. PNMR expects to provide above-average dividend growth in the near-term and to manage the payout ratio to meet its long-term target. The PNMR board will continue to evaluate the dividend on an annual basis, considering sustainability and growth, capital planning, and industry standards.

Business Focus

In addition to its strategic goals, PNMR's strategy and decision-making are focused on safely providing reliable, affordable, and environmentally responsible power to create enduring value for customers and communities. To accomplish this, PNMR works closely with customers, stakeholders, legislators, and regulators to ensure that our resource plans and infrastructure investments benefit from robust public dialogue and balance the diverse needs of our communities.

Reliable and Affordable Power

PNMR and its utilities are keenly aware of the roles they play in enhancing economic vitality in their New Mexico and Texas service territories. We believe there is a direct connection between electric infrastructure to ensure reliability and economic growth. When considering expanding or relocating to other communities, businesses consider energy affordability and energy reliability to be important factors. PNM and TNMP strive to balance service affordability with infrastructure investment to maintain a high level of electric reliability. The utilities also work to ensure that rates reflect actual costs of providing service.

Investing in PNM's and TNMP's infrastructure is critical to ensure reliability and meet future energy needs. Both utilities have long-established records of providing customers with top-tier electric reliability. In September 2011, TNMP began its deployment of smart meters in homes and businesses across its Texas service area. Through the end of 2012, TNMP had completed installation of more than 75,000 smart meters. TNMP's deployment is expected to be completed in 2016.

As part of the State of Texas' long-term initiative to create a smart electric grid, the smart meter rollout will ultimately give consumers more energy consumption data and help them make more informed decisions. In 2013, TNMP will install a new outage management system that will leverage capabilities of the smart meters to enhance the company's responsiveness to outages.

During the 2010 to 2012 period, PNM and TNMP together invested $803.7 million in substations, power plants, and transmission and distribution systems in New Mexico and Texas. In 2012, PNM announced its planned 40 MW natural gas-fired La Luz peaking generating station to be located near Belen, New Mexico. PNM anticipates filing a request in May 2013 with the NMPRC for approval for construction of the La Luz project, which is expected to begin in 2014, with the facility going into service in 2016. PNM also announced an agreement to purchase Delta, a 132 MW gas-fired peaking facility, which has served PNM jurisdictional needs under a 20-year purchase power agreement since 2000.

Environmentally Responsible Power

PNMR has a long-standing record of environmental stewardship. In 2012 and 2013, its environmental focus has been in three key areas:

•Preparing to meet New Mexico's increasing renewable energy requirements as cost-effectively as possible

• Developing strategies to meet regional haze rules at the coal-fired SJGS as cost effectively as possible while providing broad environmental benefits

•Increasing energy efficiency participation

64

Another area of emphasis is the reduction of the amount of fresh water used during the generation of power at PNM's power plants. The fresh water used per MWh generated has dropped by 22.3% since 2002, primarily due to the growth of renewable energy sources, the expansion of Afton to combined-cycle plant that has both air and water cooling systems, and the use of gray water for cooling at Luna. In addition to the above areas of focus, in 2013, the Company also will be working to reduce the amount of solid waste going to landfills through increased recycling and reduction of waste. The Company has performed well in this area in the past and has set goals for even further reductions.

Renewable Energy

In 2012, PNM filed and the NMPRC approved PNM's 2013 renewable procurement strategy. The approved strategy will almost double PNM's solar capacity with the addition of 21.5 MW of utility-owned solar capacity having an estimated cost of almost $50 million. In addition to the solar expansion, the 2013 proposal includes a 20-year agreement to purchase energy from a geothermal facility to be built near Lordsburg, New Mexico. The 10 MW facility will be the first geothermal project for the PNM system.

In addition to the 22 MW of solar currently available through the five plants constructed in 2011, PNM also owns a sixth facility, the 500-KW PNM Prosperity Energy Storage Project, which uses advanced batteries to store solar power and dispatch the energy either during high-use periods or when solar production is limited. The project features one of the largest combinations of battery storage and PV energy in the nation and involves extensive research and development of smart grid concepts with the Electric Power Research Institute, East Penn Manufacturing Co., Northern New Mexico College, Sandia National Laboratories, and the University of New Mexico. When the facility went online in September 2011, it was the nation's first solar storage facility fully integrated into a utility's power grid.

PNM's resource portfolio includes the purchase of 204 MW of wind power. PNM also purchases power from a customer-owned distributed solar generation program having an installed capacity of 19.8 MW at the end of 2012. Distributed generation, wind, and solar power are key means for PNM to meet the RPS established by the REA and related regulations issued by the NMPRC. These rules require a utility to achieve prescribed levels of energy sales from renewable sources within its generation mix, if that can be accomplished without exceeding the RCT cost limit set by the NMPRC, which aims to moderate the cost to consumers when utilities use more renewable resources.

PNM sought and received a waiver from the NMPRC excusing it from meeting the RPS in 2012 because the cost to achieve the full RPS would exceed the RCT. The 2013 plan will enable PNM to comply with the statutory RPS amount in 2013, but required a variance from the NMPRC's diversity requirements in 2013 while the proposed geothermal facilities are being constructed. Although this plan had been expected to enable PNM to achieve full RPS quantity and diversity compliance by 2014 without exceeding the RCT, delays in the permitting process for the geothermal facility have delayed its anticipated in-service date to later in 2014. PNM does not believe this delay will affect its ability to comply with the diversity requirements as amended in December 2012. PNM will continue to procure renewable resources while balancing the bill impact to customers in order to meet New Mexico's escalating RPS requirements.

SJGS

PNM continues its efforts to comply with the EPA regional haze rule in a manner that minimizes the cost impact to customers while still achieving broad environmental benefits. EPA's FIP for regional haze currently in effect requires the installation of SCRs on all four units at SJGS by September 2016.

On February 15, 2013, PNM, NMED, and EPA agreed to pursue a revised plan that could provide a new BART path to comply with federal visibility rules at SJGS. The terms of the non-binding agreement would result in the retirement of SJGS Units 2 and 3 by the end of 2017 and the installation of SNCRs on Units 1 and 4 by the later of January 31, 2016 or 15 months after EPA approval of a revised SIP from the State of New Mexico. PNM would also build a natural gas-fired peaking generating plant to be sited at SJGS to partially replace the capacity from the retired coal units. Additional base load generating capacity may also be required, which could come from PVNGS Unit 3 or additional gas-fired generation. Implementing this plan would include:

• NMED development of a revised SIP

• Approval of the revised SIP by EIB

• EPA approval of the revised SIP

• NMPRC approval of the retirement of Units 2 and 3, as well as recovery of the unrecovered investment and costs to retire those units, and plans to acquire replacement power

65

The term sheet setting forth the non-binding agreement projects EIB approval in the fourth quarter of 2013, with EPA final action in late 2014. Contemporaneously with the signing of the non-binding agreement, EPA indicated in writing that if the above plan does not move forward due to circumstances outside of the control of PNM and NMED, EPA will work with the state and PNM to create a reasonable FIP compliance schedule to reflect the time used to develop the new state plan. PNM is also exploring potential additional areas of relief, including relief from the Tenth Circuit.

In connection with the implementation of the plan, retirement of SJGS Units 2 and 3 could result in shifts in ownership among SJGS owners as may be agreed upon by the owners, including PNM acquiring additional ownership in SJGS Unit 4. Owners of the affected units also may seek approvals of their utility commissions or governing boards.

On February 25, 2013, the parties filed their status reports with the Tenth Circuit.  To demonstrate that progress has been made toward settling the Tenth Circuit litigation, information, including the non-binding agreement and its accompanying timeline, was submitted to the court. Following the parties' submission of their status reports, on February 28, 2013, the Tenth Circuit referred the litigation to the Tenth Circuit Mediation Office, which has authority to require the parties to attend mediation conferences to informally resolve issues in the pending appeals.

This revised BART plan would achieve similar visibility improvements as the installation of SCRs on all four units at SJGS. It has the added advantage of reducing other emissions beyond NOx, including SO₂, particulate matter, CO₂, and mercury, as well as reducing water usage. Detailed replacement power strategies also would be finalized. PNM believes adequate replacement power alternatives will be available to meet its generation needs and ensure reliability. PNM can provide no assurance that the requirements of this plan will be accomplished at all or within the required timeframes.

Additional information about BART at SJGS is contained in Note 16 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K and in Note 9.

In addition to the regional haze rule, SJGS is required to comply with other rules currently being developed or implemented that affect coal-fired generating units. Because of environmental upgrades completed in 2009, SJGS is well positioned to outperform the mercury limit imposed by EPA in the 2011 Mercury and Air Toxics Standards. The major environmental upgrades on each of the four units at SJGS have significantly reduced emissions of NOx, SO₂, particulate matter, and mercury. Since 2006, SJGS has reduced NOx emissions by 43 percent, SO₂ by 69 percent, particulate matter by 64 percent, and mercury by 99 percent.

Energy Efficiency

Energy efficiency also plays a significant role in helping to keep customers' electricity costs low while continuing to meet their energy needs. PNM's and TNMP's energy efficiency and load management portfolios continue to achieve robust results. In 2012, annual energy saved as a result of PNM's portfolio of energy efficiency programs was approximately 79 GWh. This is equivalent to the consumption of approximately 10,700 homes in PNM's service territory. PNM's load management and energy efficiency programs also help lower peak demand requirements. TNMP's energy efficiency programs in 2012 resulted in energy savings totaling an estimated 12.8 GWh.

Creating Value for Customers and Communities

Through outreach, collaboration, and various community-oriented programs, PNMR has a demonstrated commitment to build productive relationships with stakeholders, including customers, regulators, legislators, and intervenors.

Building off work that began in 2008, PNM has continued outreach efforts to connect low-income customers with nonprofit community service providers offering support and help with such needs as utility bills, food, clothing, medical programs, services for seniors, and weatherization. In 2012, PNM hosted 23 community events throughout its service territory to assist low-income customers. Furthermore, the PNM Good Neighbor Fund provided $1.0 million of assistance with utility bills to 10,216 families in 2012.

The PNM Resources Foundation helps nonprofits become more energy efficient through Reduce Your Use grants. For 2012, the foundation awarded $0.3 million to support 55 projects in New Mexico to provide shade structure installations, window replacements, and efficient appliance purchases. Since the program's inception in 2008, Reduce Your Use grants have provided nonprofit agencies in New Mexico with a total of $1.1 million of support.

66

PNM also expanded its environmental stakeholder outreach in 2012, piloting small environmental stakeholder dialogue groups on key issues such as renewable energy and energy efficiency planning. PNM also employed proactive stakeholder outreach in two key projects - the development of the PNM's renewable energy procurement plans that involved distributed solar energy developers early in the conversation and the siting of the planned gas-fired peaking generation facility near Belen, New Mexico, which featured in-depth community involvement and education early in the planning stages of the project. In both cases highly favorable outcomes were achieved, and controversial negative media coverage was virtually eliminated.

Economic Factors

In the three months ended March 31, 2013, PNM experienced a decrease in weather and leap-year normalized, retail load of 1.9% compared to the three months ended March 31, 2012. New Mexico businesses seem to be taking a long time to recover from the economic downturn.  In particular, the Albuquerque metropolitan area continues to lag the nation in economic recovery.  Based on the current trends, load could be down 1% for the full year 2013 compared to 2012.  However, since PNM's largest quarter is third quarter, economic conditions may improve by that point, which could cause load to increase. TNMP experienced an increase in weather and leap-year normalized, retail load of 2.2% in the three months ended March 31, 2013 compared to 2012. In recent years, New Mexico and Texas have fared better than the national average in unemployment. However, New Mexico's figures may be misleading due to people dropping out of the workforce. Employment growth is a better indicator, as Texas leads the way with growth rates well above the national rate while New Mexico's employment is relatively flat.

Results of Operations

A summary of net earnings attributable to PNMR is as follows:

	Three Months Ended March 31,
	2013		2012		Change
	(In millions, except per share amounts)
Net earnings attributable to PNMR	$	10.6	$	17.1	$	(6.5	)

PNMR's operational results were affected by the following:

• Rate increases for PNM and TNMP - Additional information about these rate increases is provided in Note 17 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K and Note 10

• Net unrealized losses on mark-to-market economic hedges for sales and fuel costs not recoverable under PNM's FPPAC

• Lower retail load at PNM partially offset by higher retail load at TNMP

• Other factors impacting results of operation for each segment are discussed under Results of Operations below

Liquidity and Capital Resources

The Company has revolving credit facilities that provide capacities for short-term borrowing and letters of credit of $300.0 million for PNMR and $400.0 million for PNM, both of which expire in October 2017. In addition, TNMP has a $75.0 million revolving credit facility, which expires in December 2015. Total availability for PNMR on a consolidated basis was $653.4 million at May 1, 2013. The Company utilizes these credit facilities and cash flows from operations to provide funds for both construction and operational expenditures. PNMR also has intercompany loan agreements with each of its subsidiaries.

The Company projects that its total capital requirements, consisting of construction expenditures and dividends, will total $2,062.8 million for 2013-2017, including amounts expended through March 31, 2013. The construction expenditures include additional renewable resources anticipated to be required to meet the RPS, additional peaking resources needed to meet needs outlined in PNM's current IRP, and environmental upgrades at Four Corners. This estimate does not include any amounts related to environmental upgrades at SJGS that ultimately may be required by EPA to address regional haze or expenditures that could be required to replace capacity should environmental control at SJGS involve shutdown of one or more SJGS units (Note 9). In addition to internal cash generation, the Company anticipates that it will be necessary to obtain additional long-term financing in the form of debt refinancing, new debt issuances, and/or new equity in order to fund its capital requirements through 2017. The Company currently believes that its internal cash generation, existing credit arrangements, and access to public and private capital markets will provide sufficient resources to meet the Company's capital requirements.

RESULTS OF OPERATIONS

Segment Information

For the three months ended March 31, 2013, retail load was lower compared to the three months ended March 31, 2012 reflecting a continued sluggish economy in New Mexico. In particular, the Albuquerque metropolitan area continues to lag the nation in economic recovery. In spite of the economic pressures, PNM experienced modest customer growth of 0.5% and the unemployment rate in New Mexico remains lower than the national rate. The decrease in PNM's weather and leap-year normalized, retail load of was 1.9% in 2013 compared to 2012. Lower retail revenues and margins of $2.1 million were primarily driven by retail load decreases in the commercial and industrial customer classes, which continue to show considerable weakness. New Mexico businesses seem to be taking a long time to recover from the economic downturn. These decreases were partly offset by an increase in the residential class mainly due to colder weather. Based on the current trends, load could be down 1% for the full year 2013 compared to 2012.  However, since PNM's largest quarter is third quarter, economic conditions may improve by that point, which could cause load to increase.

PNM provides economy energy services to a major customer. The only impact in margin for this customer is from minor ancillary services, and other changes in revenues and cost of energy are a pass through with no impact to margin. Other sales for resale revenues and volumes increased for the three months ended March 31, 2013, primarily due to reduced off-system sales at SJGS in 2012 resulting from the fire incident at the mine providing coal to SJGS. Increased off-system sales from SJGS in 2013 are included in PNM's FPPAC and do not impact margin. See Note 9 for more discussion on the SJGS mine fire incident.

For the three months ended March 31, 2013 lower retail transmission revenue and an increase in short-term transmission purchases from other providers reduced margin by $0.3 million compared to 2012. An increase in rates charged to a wholesale firm-requirements customer increased revenue and margin by $2.0 million in the three months ended March 31, 2013 compared to 2012.

PNM offers several energy efficiency programs and initiatives to its retail customers regulated by the NMPRC. In addition, PNM is allowed to earn incentives on these programs, based on energy savings of the programs. PNM recovers these energy efficiency program costs via a rate rider. For the three months ended March 31, 2013, revenues and margin from the energy efficiency rider improved by $0.6 million, primarily due to additional incentives earned compared to 2012. Other changes in energy efficiency revenues are offset by changes in operating expenses.

In August 2012, PNM implemented its renewable energy rider, a mechanism approved by the NMPRC, which recovers renewable energy procurement costs, including the investment in and an allowed return on the 22 MW PNM-owned solar PV facilities incurred to meet the RPS. See Note 10. For the three months ended March 31, 2013, revenues increased by $4.7 million due to this rider and cost of energy, reflecting the purchase of RECs, increased by $1.5 million. Such revenues include a return on investment of $0.9 million and the remaining revenues are for recovery of renewable energy operating, depreciation and interest expenses.

For the three months ended March 31, 2013, higher unregulated revenues of $1.5 million and margin of $1.3 million associated with PNM's share of PVNGS Unit 3, which is excluded from retail regulation, were due to favorable market power prices on sales compared to three months ended March 31, 2012, partially offset by increases in nuclear fuel costs.

Changes in unrealized mark-to-market gains and losses are based on economic hedges in place for sales and fuel costs not covered under the FPPAC, primarily associated with PVNGS Unit 3. Unrealized losses of $4.9 million for the three months ended March 31, 2013 compared to unrealized gains of $3.5 million for the three months ended March 31, 2012, decreased margin by $8.4 million.

For the three months ended March 31, 2013 operating expenses decreased by $0.9 million, including reductions due to timing of planned outages at SJGS and PVNGS of $2.1 million and $0.8 million. These were offset by higher outage expense at Four Corners of $0.4 million. In addition, bad debt expense decreased by $0.7 million due to improved collection experience. The decreases were offset by higher incentive compensation expense of $0.7 million and higher property, regulatory and payroll taxes of $0.8 million.

For the three months ended March 31, 2013, depreciation expense increased by $2.2 million primarily due to amortization of previously deferred costs related to the 22 MW PNM-owned solar PV facilities, which beginning in August 2012 are being recovered through a rate rider, as well as higher depreciation due to an increase in utility plant in service.

For the three months ended March 31, 2013, other income (deductions) was $4.2 million lower than 2012. Lower gains on investments held by the NDT reduced other income by $2.9 million in 2013 compared to 2012. Lower interest income on

70

PVNGS lessor notes of $0.6 million due to lower outstanding balances and lower equity AFUDC of $0.7 million also reduced other income.

For the three months ended March 31, 2013, interest expense increased $1.5 million primarily due to the deferral of interest costs associated with the 22 MW PNM-owned solar PV facilities during 2012, which are now being recovered through a rate rider.

Implementation of rate increases in March 2013 and September 2012 resulted in higher revenues and margins of $0.7 million in the three months ended March 31, 2013 compared to 2012. See Note 10. After adjusting for weather impacts and transmission service customers, usage per customer and average number of customers were higher in TNMP's service area increasing revenues by $1.0 million for the three months ended March 31, 2013 compared to 2012. In addition, cooler temperatures in the three months ended March 31, 2013 compared to milder weather in 2012 resulted in higher usage increasing revenues and margin $0.4 million. Differences between revenues and costs charged by transmission providers are deferred and recovered through a transmission cost recovery factor, resulting in higher margin of $0.4 million in the three months ended March 31, 2013 compared to 2012. For the three months ended March 31, 2013, the AMS surcharge improved revenues and margin by $1.0 million, which offset increases in operating expenses and depreciation.

Customer related expenses and administrative and general expenses associated with the AMS deployment increased operating expenses $0.6 million for the three months ended March 31, 2013 compared to 2012. Higher vegetation management expense of $0.3 million and higher energy efficiency program expenses of $0.4 further increased operating expenses for the three months ended 2013.

The increase in depreciation and amortization expense for the three months ended March 31, 2013 is mainly due to the deployment of AMS on TNMP's system, which is recovered through the surcharge discussed above.

Segment earnings (loss)	$	(4.5	)	$	(3.6	)	$	(0.9	)

Operating expenses for Corporate and Other are net of amounts allocated to PNM and TNMP under shared service agreements. Operating expenses decreased in the three months ended March 31, 2013 compared to 2012 primarily due to legal and consulting expenses incurred in 2012 related to the Company's union negotiations and the restructuring of outsourcing arrangements for information technology. These expenses did not recur in 2013.

Depreciation and amortization expense decreased $0.2 million in the three months ended March 31, 2013 compared to 2012 due to amortization of leasehold improvements during 2012 for part of the Company's corporate headquarters that was abandoned and fully amortized during 2012. Changes in depreciation and amortization are offset in operating expenses as a result of allocation of these costs to other business segments. PNM and TNMP deferred their allocations of the accelerated amortization of leasehold improvements as regulatory assets to be recovered through rates.

The change in other income and deductions is primarily due to lower performance on other investments during 2012 which did not recur during the three months ended March 31, 2013.

During the three months ended March 31, 2013, income (taxes) benefits includes the impairment of New Mexico wind energy production credits, which after federal income tax benefit, amounted to $1.5 million. See Note 12. No such impairment occurred in 2012.

LIQUIDITY AND CAPITAL RESOURCES

Statements of Cash Flows

The changes in PNMR’s cash flows for the three months ended March 31, 2013 compared to March 31, 2012 are summarized as follows:

	Three Months Ended March 31,
	2013				2012			Change
				(In millions)
Net cash flows from:
Operating activities	$	(1.4	)		$	13.6		$	(15.0	)
Investing activities	(62.2		)		(69.6		)	7.4
Financing activities	59.7				47.9			11.8
Net change in cash and cash equivalents	$	(3.9	)		$	(8.1	)	$	4.2

73

The changes in PNMR's cash flows from operating activities relate primarily to a decrease in cash flows from operating activities at PNM, including a decrease in receipt of governmental grants of $20.9 million, refunds of $15.2 million to transmission customers related to the settlement of PNM's transmission rate case, and decreases in accounts payable. Contributions to the PNM and TNMP pension and other postretirement benefit plans of $61.5 million in the three months ended March 31, 2013 compared to $84.1 million in 2012 partially offset these decreases.

The changes in PNMR's cash flows from investing activities relate primarily to a decrease of $10.4 million in utility plant additions in the three months ended March 31, 2013 compared to 2012. Utility plant additions at PNM were $22.3 million lower in the three months ended March 31, 2013 than 2012, including $12.4 million lower nuclear fuel purchases, due to the acceleration of fuel deliveries in 2012 related to the financial difficulties of a supplier; a reduction of $9.0 million in renewable energy additions, primarily related to payments in 2012 for the 22 MW of PNM-owned solar PV completed late in 2011; and a $3.5 million reduction in generation additions related to SJGS. TNMP utility plant additions increased $11.5 million in the three months ended March 31, 2013 compared to 2012, including increases in AMS additions of $3.2 million and other transmission and distribution additions of $9.7 million. Corporate plant additions increased $4.4 in in the three months ended March 31, 2013 compared to 2012, primarily related to payments in 2013 for renovations of the corporate headquarters building completed in late 2012.

The changes in cash flows from financing activities primarily relate to a $17.5 million greater increase in net short-term borrowings in the three months ended March 31, 2013 compared to 2012. The greater increase in 2013 reflects additional borrowings to offset the reduction in cash flows from operating activities, partially offset by the reduction in investing activities, as described above. The Company's operations are seasonal with the greatest amount of cash collections from customers following the higher revenues occurring in the summer months. Therefore, historically short-term borrowings are used in the first quarter of the year to offset construction expenditures and operations. Cash outflows for awards of common stock, net of proceeds from the exercise of options, increased $1.3 million due to an increase in the price of PNMR's common stock and the increased utilization of restricted stock awards rather than stock options.

Financing Activities

See Note 6 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K, for additional information concerning the Company's financing activities. On March 6, 2013, TNMP commenced an offer to exchange any and all of TNMP's $265.5 million aggregate principal amount outstanding 9.50% First Mortgage Bonds, due 2019, Series 2009A, for a new series of 6.95% First Mortgage Bonds due 2043, Series 2013A, and up to $140 in cash for each $1,000 of bonds exchanged. Settlement of the exchange offer occurred on April 3, 2013. Upon settlement, TNMP issued $93.2 million of 6.95% First Mortgage Bonds and paid an aggregate of $13.0 million in cash in exchange for $93.2 million of 9.50% First Mortgage Bonds, in addition to payment of accrued and unpaid interest on the exchanged bonds.

On April 22, 2013, PNM entered into the $75.0 million PNM Term Loan Agreement. Funding occurred on April 22, 2013, at which time the funds were used to repay $75.0 million in borrowings made under the PNM Revolving Credit Facility.

Capital Requirements

Total capital requirements consist of construction expenditures and cash dividend requirements for PNMR common stock and PNM preferred stock. Key activities in PNMR's current construction program include:

• Upgrading generation resources and additional renewable energy projects

• Expanding the electric transmission and distribution systems

• Purchasing nuclear fuel

Projected capital requirements, including amounts expended through March 31, 2013, are:

	2013		2014-2017		Total
	(In millions)
Construction expenditures	$	390.1	$	1,408.8	$	1,798.9
Dividends on PNMR common stock	51.0		210.3		261.3
Dividends on PNM preferred stock	0.5		2.1		2.6
Total capital requirements	$	441.6	$	1,621.2	$	2,062.8

74

The construction expenditure estimates are under continuing review and subject to ongoing adjustment, as well as to Board review and approval. The construction expenditures above include additional renewable resources anticipated to be required to meet the RPS, additional peaking resources needed to meet needs outlined in PNM's current IRP, and environmental upgrades at Four Corners of $71.9 million estimated to be expended through 2017. The construction expenditures above do not include any amounts related to environmental upgrades at SJGS that ultimately may be required by EPA to address regional haze or expenditures that could be required to replace capacity should environmental control at SJGS involve shutdown of one or more SJGS units. See Note 9 and Commitments and Contractual Obligations below. The ability of PNMR to pay dividends on its common stock is dependent upon the ability of PNM and TNMP to be able to pay dividends to PNMR. Note 5 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K describes regulatory and contractual restrictions on the payment of dividends by PNM and TNMP.

During the three months ended March 31, 2013, PNMR met its capital requirements and construction expenditures through cash generated from operations, as well as its liquidity arrangements.

In addition to the capital requirements for construction expenditures and dividends, the Company has long-term debt that must be paid or refinanced at maturity. Note 6 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K contains information about the maturities of long-term debt. The Company has from time to time refinanced or repurchased portions of its outstanding debt before scheduled maturity. See Financing Activities above. Depending on market conditions, the Company may refinance other debt issuances or make additional debt repurchases in the future.

Liquidity

PNMR's liquidity arrangements include the PNMR Revolving Credit Facility and the PNM Revolving Credit Facility that both expire in 2017 and the TNMP Revolving Credit Facility that expires in December 2015. The PNMR Revolving Credit Facility has a financing capacity of $300.0 million, the PNM Revolving Credit Facility has a financing capacity of $400.0 million, and the TNMP Revolving Credit Facility has a financing capacity of $75.0 million. The Company believes the terms and conditions of its facilities are consistent with those of other investment grade revolving credit facilities in the utility industry.  In December 2012, PNMR entered into the PNMR Term Loan Agreement, borrowed $100.0 million under that agreement, and used the funds to repay $100.0 million in borrowings made under the PNMR Revolving Credit Facility. On April 22, 2013, PNM entered into the PNM Term Loan Agreement, borrowed $75.0 million under that agreement, and used the funds to repay $75.0 million in borrowings made under the PNM Revolving Credit Facility. Each of these facilities contains one financial covenant, which requires the maintenance of debt-to-capital ratios of less than or equal to 65%.  These ratios for PNMR and PNM reflect the present value of payments under the PVNGS and EIP leases as debt.

The revolving credit facilities provide short-term borrowing capacity and also allow letters of credit to be issued. Letters of credit reduce the available capacity under the facilities. The Company utilizes these credit facilities and cash flows from operations to provide funds for both construction and operational expenditures. The Company's business is seasonal with more revenues and cash flows from operations being generated in the summer months. In general, the Company relies on the credit facilities to be the initial funding source for construction expenditures. Accordingly, borrowings under the facilities increase over time. Depending on market and other conditions, the Company will periodically sell long-term debt and use the proceeds to reduce the borrowings under the credit facilities. Short-term borrowings at PNMR ranged from $21.5 million to $54.2 million during the three months ended March 31, 2013 and from $14.0 million to $105.7 million during the three months ended March 31, 2012. PNM short-term borrowings ranged from $9.8 million to $130.8 million during the three months ended March 31, 2013 and from $44.1 million to $167.9 million during the three months ended March 31, 2012. TNMP borrowings ranged from zero to $25.0 million during the three months ended March 31, 2013 and there were no borrowings during the three months ended March 31, 2012. At March 31, 2013, average interest rates were 1.96% for the PNMR Revolving Credit Facility, 1.335% for the PNMR Term Loan Agreement, 1.71% for the PNM Revolving Credit Facility, and 1.83% for the TNMP Revolving Credit Facility.

The Company currently believes that its capital requirements can be met through internal cash generation, existing credit arrangements, and access to public and private capital markets. To cover the difference in the amounts and timing of internal cash generation and cash requirements, the Company intends to use short-term borrowings under its current and future liquidity arrangements. However, if difficult market conditions experienced during 2008 and 2009 return or worsen, the Company may not be able to access the capital markets or renew credit facilities when they expire. Should that occur, the Company would seek to improve cash flows by reducing capital expenditures and exploring other available alternatives. Also, PNM may consider seeking authorization for the issuance of first mortgage bonds to improve access to the capital markets.

75

In addition to its internal cash generation, the Company anticipates that it will be necessary to obtain additional long-term financing to fund its capital requirements through 2017. This could include debt refinancing, new debt issuances, and/or new equity.

The Company's ability to access the credit and capital markets at a reasonable cost is largely dependent upon its:

• Ability to earn a fair return on its investments

• Results of operations

• Ability to obtain required regulatory approvals

• Conditions in the financial markets

• Credit ratings 

The credit ratings for PNMR, PNM, and TNMP were set forth under the heading Liquidity in the MD&A contained in the 2012 Annual Reports on Form 10-K. On April 5, 2013, S&P raised the corporate credit ratings and the senior debt ratings for PNMR, PNM, and TNMP, as well as the preferred stock rating for PNM. S&P retained the outlook as stable for all entities. As of May 1, 2013, ratings on the Company's securities were as follows:

	PNMR	PNM	TNMP
S&P
Senior secured debt	*	*	A-
Senior unsecured debt	BBB-	BBB	*
Preferred stock	*	BB+	*
Moody's
Senior secured debt	*	*	A3
Senior unsecured debt	Ba1	Baa3	*
Preferred stock	*	Ba2	*

* Not applicable

Investors are cautioned that a security rating is not a recommendation to buy, sell, or hold securities, that it is subject to revision or withdrawal at any time by the assigning rating organization, and that each rating should be evaluated independently of any other rating.

A summary of liquidity arrangements, which do not include the PNMR Term Loan Agreement or the PNM Term Loan Agreement, as of May 1, 2013 is as follows:

	PNMR Separate		PNM Separate		TNMP Separate		PNMR Consolidated
			(In millions)
Financing capacity - revolving credit facility	$	300.0	$	400.0	$	75.0	$	775.0
Amounts outstanding as of May 1, 2013:
Revolving credit facility	60.3		16.2		30.0		106.5
Letters of credit	11.3		3.5		0.3		15.1
Total short–term debt and letters of credit	71.6		19.7		30.3		121.6
Remaining availability as of May 1, 2013	$	228.4	$	380.3	$	44.7	$	653.4
Invested cash as of May 1, 2013	$	4.5	$	—	$	—	$	4.5

The above table excludes intercompany debt. The remaining availability under the revolving credit facilities at any point in time varies based on a number of factors, including the timing of collections of accounts receivables and payments for construction and operating expenditures.

For offerings of securities registered with the SEC, PNMR has a shelf registration statement expiring in March 2014. This shelf registration statement has unlimited availability and can be amended to include additional securities, subject to certain

76

restrictions and limitations. PNMR can also offer new shares of common stock through the PNM Resources Direct Plan under a separate SEC shelf registration statement that expires in August 2015. PNM has a shelf registration statement for up to $440.0 million of senior unsecured notes that will expire in May 2014.

PNMR's off-balance sheet arrangements include PNM's operating lease obligations for PVNGS Units 1 and 2, the EIP transmission line, and Delta. These arrangements help ensure PNM the availability of lower-cost generation needed to serve customers. See MD&A - Off-Balance Sheet Arrangements and Notes 7, 9, and 16 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K. See Note 3 for additional information concerning the PVNGS Leases and Delta. See Note 9 for additional information concerning the EIP transmission line.

Commitments and Contractual Obligations

PNMR, PNM, and TNMP have contractual obligations for long-term debt, operating leases, construction expenditures, purchase obligations, and certain other long-term obligations. See MD&A - Commitments and Contractual Obligations in the 2012 Annual Reports on Form 10-K.

Contingent Provisions of Certain Obligations

As discussed in the 2012 Annual Reports on Form 10-K,PNMR, PNM, and TNMP have a number of debt obligations and other contractual commitments that contain contingent provisions. Some of these, if triggered, could affect the liquidity of the Company. In the unlikely event that the contingent requirements were to be triggered, PNMR, PNM, or TNMP could be required to provide security, immediately pay outstanding obligations, or be prevented from drawing on unused capacity under certain credit agreements. The contingent provisions also include contractual increases in the interest rate charged on certain of the Company's short-term debt obligations in the event of a downgrade in credit ratings. The Company believes its financing arrangements are sufficient to meet the requirements of the contingent provisions. No conditions have occurred that would result in any of the above contingent provisions being implemented.

OTHER ISSUES FACING THE COMPANY

Climate Change Issues

Background

In 2012, PNM's generating plants emitted approximately 6.7 million metric tons of CO₂, which comprises the vast majority of its GHG.  By comparison, the total GHG in the United States in 2011, the latest year for which EPA has published this data, were approximately 6.7 billion metric tons, of which approximately 5.6 billion metric tons were CO₂.  According to EPA data, electricity generation accounted for approximately 2.2 billion metric tons, or 39%, of the CO₂ emissions.

PNM has several programs underway to reduce GHG from its generating plants, thereby reducing its exposure to climate change regulation. See Note 10. In 2011, PNM completed construction of 22 MW of utility-scale solar generation located at five sites on PNM's system throughout New Mexico. In 2013, PNM is expanding its renewable energy portfolio by constructing 21.5 MW of utility-scale solar generation that will be on-line by the end of the year and has signed a 20 year PPA for the output of a 10 MW geothermal facility to be in service in 2014. Additionally, PNM has a customer distributed solar generation program that is expected to grow distributed solar from almost 20 MW installed at the end of 2012 to over 44 MW by the end of 2013. Once fully subscribed, the distributed solar programs will reduce PNM's production from fossil-fueled electricity generation by 116 GWh per year. PNM offers its customers a comprehensive portfolio of energy efficiency and load management programs, with a 2012 budget of over $17 million, that PNM estimates saved approximately 79 GWh of electricity in 2012. Over the next 18 years, PNM projects the expanded energy efficiency and load management programs will provide the equivalent of approximately 12,185 GWh of electricity, which will avoid at least 6.1 million metric tons of CO₂ based upon projected emissions from PNM's system-wide resources. These estimates are subject to change given that it is difficult to accurately estimate avoidance because of the high uncertainty of many of the underlying variables and complex interrelationships between those variables, including changes in demand for electricity.

Management periodically updates the Board on implementation of corporate environmental policy and the Company's environmental management systems, promotion of energy efficiency, and use of renewable resources.  The Board is also advised of the Company's practices and procedures to assess the sustainability impacts of operations on the environment.  The Board regularly considers associated issues around climate change, the Company's GHG exposures, and potential financial consequences that might result from potential federal and/or state regulation of GHG.

At December 31, 2012, approximately 81.8% of PNM's owned and leased generating capacity, all of which is located within the United States, consisted of coal or gas-fired generation that produces GHG. The Company does not anticipate any direct impact from any near-term international accords. Based on current forecasts, the Company does not expect its output of GHG from existing sources to increase significantly in the near-term. Many factors affect the amount of GHG, including plant performance.  For example, if PVNGS experienced prolonged outages, PNM might be required to utilize other power supply resources such as gas-fired generation, which could increase GHG. If new natural gas-fired generation resources are added to meet increased load as anticipated in PNM's current IRP, GHG would be incrementally increased. As described in Note 9, on February 15, 2013, PNM, NMED, and EPA agreed to pursue a strategy to address the regional haze requirements of the CAA at the coal-fired SJGS, which would include the shutdown of SJGS Units 2 and 3. If implemented, shutdown of those units would reduce PNM's GHG (based on 2012 data) by approximately 1.9 million tons of CO₂ per year beginning in 2018. That agreement also contemplates that gas-fired generation would be built to partially replace the retired capacity. Although replacement power strategies have not been finalized, the reduction in GHG from the retirement of coal-fired generation would be greater than the increase in GHG from replacement with gas-fired generation.

Because of PNM's dependence on fossil-fueled generation, any legislation that imposes a limit or cost on GHG will impact the cost at which electricity is produced. While PNM expects to recover that cost through rates, the timing and outcome of proceedings for cost recovery is uncertain. In addition, to the extent that any additional costs are recovered through rates, customers may reduce their demand, relocate facilities to other areas with lower energy costs, or take other actions that ultimately will adversely impact PNM.

Given the geographic location of its facilities and customers, PNM generally has not been exposed to the extreme weather events and other physical impacts commonly attributed to climate change, with the exception of periodic drought conditions. Climate changes are generally not expected to have material consequences in the near-term. Drought conditions in northwestern New Mexico could impact the availability of water for cooling coal-fired generating plants. Water shortage sharing agreements have been in place since 2004, although no shortage has been declared due to sufficient precipitation in the San Juan River basin.

78

PNM also has a supplemental water contract in place with the Jicarilla Tribe to help address any water shortages from primary sources. The contract expires on December 31, 2016.  TNMP has operations in the Gulf Coast area of Texas, which experiences periodic hurricanes and drought conditions. In addition to potentially causing physical damage to TNMP-owned facilities, which disrupt the ability to transmit and/or distribute energy, hurricanes can temporarily reduce customers' usage and demand for energy.

EPA Regulation

In April 2007, the United States Supreme Court held that EPA has the authority to regulate GHG under the CAA.  This decision heightened the importance of this issue for the energy industry.  In December 2009, EPA released its endangerment finding stating that the atmospheric concentrations of six key greenhouse gases (CO₂, methane, nitrous oxides, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride) endanger the public health and welfare of current and future generations. In May 2010, EPA released the final PSD and Title V Greenhouse Gas Tailoring Rule (the "Tailoring Rule") to address GHG from stationary sources under the CAA permitting programs. The purpose of the rule is to “tailor” the applicability of two programs, PSD and Title V operating permit programs, to avoid impacting millions of small GHG emitters. The rule focuses on the largest sources of GHG, including fossil-fueled electric generating units. This program currently covers new construction projects that emit GHG of at least 100,000 tons per year (even if PSD is not triggered for other pollutants). In addition, modifications at existing facilities that increase GHG by at least 75,000 tons per year will be subject to PSD permitting requirements, even if they do not significantly increase emissions of any other pollutant. All of PNM's fossil-fueled generating plants are potentially subject to the Tailoring Rule because of the magnitude of non-GHG, but the existing plants do not have any currently planned projects that would trigger PSD permitting for GHG. Any newly constructed power plant would likely be subject to the Tailoring Rule.

On June 26, 2012, the D.C. Circuit rejected challenges to EPA's 2009 GHG endangerment finding, GHG emission standards for light-duty vehicles, PSD Interpretive Memorandum (EPA's so-called GHG "Timing Rule"), and Tailoring Rule. The Court found that EPA's endangerment finding and its light-duty vehicle rule "are neither arbitrary nor capricious," that "EPA's interpretation of the governing CAA provisions is unambiguously correct," and that "no petitioner has standing to challenge the Timing and Tailoring Rules."

On March 27, 2012, EPA issued its proposed carbon pollution standards for the emission of GHG from new fossil-fueled electric generating units (“EGUs”). The proposed NSPS sets a limit of 1,000 lb CO₂/MWh and covers newly constructed fossil-fueled EGUs that are larger than 25 MW. The proposed limit is based on the performance of natural gas combined cycle technology. Therefore, coal-fired power plants would likely only be able to comply with the standard by using carbon capture and sequestration technology. The proposed rule includes an exemption for simple cycle EGUs. However, during the comment period, EPA solicited comments on whether to drop the exemption and instead exempt any fossil-fueled EGU that limits electric generation to one-third of its annual generating capacity. The proposed rule, as written, does not include limits that apply to existing power plants, or proposed plants that already have a complete preconstruction permit and commence construction within 12 months of the issuance of the proposed rule. The proposal is the first NSPS issued for CO₂, and although it is limited to new sources, it has potential far-reaching implications for the utility industry. When finalized, the standard could serve as the floor for BACT analysis for PSD permitting for new GHG sources under the Tailoring Rule. The proposed rule was published in the Federal Register on April 13, 2012. EPA accepted comment on the proposed rule through June 25, 2012. On April 12, 2013, EPA announced it would delay the issuance of the GHG NSPS for new sources. EPA received over two million comments on the proposed rule. EPA has not set a timeline for publishing a revised rule. 

Completion of the proposed NSPS for new EGUs is a prerequisite for EPA to promulgate GHG standards for existing sources. An EPA proposal to establish a GHG NSPS for existing sources was expected in April 2013, but the actual date is uncertain due to the delay discussed above. In setting the standards, EPA has historically used technology-based performance standards on emission rates. The only end-of-pipe emission control technology for coal and gas fired power plants available for GHG reduction is carbon capture and sequestration, which is not yet a commercially demonstrated technology. There are limited efficiency enhancement measures that may be available to a subset of the existing EGUs; however, such measures would provide only marginal GHG improvements.

EPA regulation of GHG from large stationary sources will impact PNM's fossil-fueled EGUs. Impacts could involve investments in efficiency improvements and/or control technologies at the fossil-fueled generating plants. Although, currently there are no commercially viable GHG control technologies for existing EGUs, such technologies may become viable in the future. It is also possible that the costs of such improvements or technologies could impact the economic viability of some plants.

The impact of EPA's regulation of GHG to PNM is unknown because the regulatory requirements, including BACT implications and NSPS requirements, are still developing. PNM estimates that implementation of an alternative SIP for BART

79

at SJGS, which requires the installation of SNCRs on Units 1 and 4 by January 2016 and the retirement of SJGS Units 2 and 3 by the end of 2017, will result in a 28% CO₂ reduction from PNM 2012 system-wide emissions from all PNM-owned generating facilities by 2020.

Federal Legislation

Prospects for enactment of legislation imposing a new or enhanced regulatory program to address climate change in the new Congress are unlikely in 2013, although there is growing interest among some policymakers in addressing climate change and there may be legislation in the future.  Instead, EPA is the primary venue for GHG regulation in the near future, especially for coal-fired units. PNM has assessed, and continues to assess, the impacts of potential climate change legislation or regulation on its business.  This assessment is preliminary, and future changes arising out of the legislative or regulatory process could impact the assessment significantly.  PNM's assessment includes assumptions regarding the specific GHG limits, the timing of implementation of these limits, the level of emissions allowances allocated and the level that must be purchased, the development of technologies for renewable energy and to reduce emissions, the cost of emissions allowances, the degree to which offsets may be used for compliance, and provisions for cost containment. Moreover, the assessment assumes various market reactions such as with respect to the price of coal and gas and regional plant economics.  These assumptions, at best, are preliminary and speculative. However, based upon these assumptions, the enactment of climate change legislation would likely, among other things, result in significant compliance costs, including significant capital expenditures by PNM, and could jeopardize the economic viability of certain generating facilities. See Note 9.  In turn, these consequences would lead to increased costs to customers and could affect results of operations, cash flows, and financial condition if the incurred costs are not fully recovered through regulated rates. Higher rates could also contribute to reduced demand for electricity.  PNM's assessment process is ongoing, but too preliminary and speculative at this time for the meaningful prediction of financial impact.

State and Regional Activity

Pursuant to New Mexico law, each utility must submit an IRP to the NMPRC every three years to evaluate renewable energy, energy efficiency, load management, distributed generation, and conventional supply-side resources on a consistent and comparable basis.  The IRP is required to take into consideration risk and uncertainty of fuel supply, price volatility, and costs of anticipated environmental regulations when evaluating resource options to meet supply needs of the utility's customers.  The NMPRC issued an order in June 2007, requiring that New Mexico utilities factor a standardized cost of carbon emissions into their IRPs using prices ranging between $8 and $40 per metric ton of CO₂ emitted and escalating these costs by 2.5% per year.  Under the NMPRC order, each utility must analyze these standardized prices as projected operating costs.  Reflecting the developing nature of this issue, the NMPRC order states that these prices may be changed in the future to account for additional information or changed circumstances.  However, PNM is required to use these prices for purposes of its IRP, and the prices may not reflect the costs that it ultimately will incur.  PNM's IRP filed with the NMPRC on July 18, 2011 (Note 10) showed that while consideration of the NMPRC required carbon emissions costs did not significantly change the resource decisions regarding future facilities over the next 20 years, it did slightly impact the projected in-service dates of some of the identified resources.  Much higher GHG costs than assumed in the NMPRC analysis are necessary to impact future resource decisions. The primary consequence of the standardized cost of carbon emissions was an increase to generation portfolio costs. In recent years, New Mexico also adopted regulations to directly limit GHG from larger sources, including EGUs. However, these regulations have been repealed. In November 2010, the EIB adopted a regional GHG cap and trade program proposed by the NMED. The NMED GHG program was intended to implement, in New Mexico, the regional cap and trade program developed by the Western Climate Initiative (“WCI") which is an organization formerly comprised of seven western states, including New Mexico, and three Canadian provinces. The NMED GHG regulation would have capped GHG emissions based on a 2011 emission baseline. Thereafter, NMED would grant GHG allowances to covered sources based on their individual emission baseline. The available allowances would decline by 2% each succeeding year requiring sources to either reduce GHG emissions by the requisite amount or purchase emission allowances from a yet-to-be established regional trading market. The required GHG reductions under the NMED program were not to be triggered until the available trading market for GHG allowances consisted of 100 million metric tons or more. New Mexico, by itself, had insufficient regulated GHG emissions to establish the requisite trading market.

PNM and other public utilities and industry groups challenged the NMED GHG cap and trade program in the New Mexico Court of Appeals. During the pendency of these appeals, the EIB agreed to consider a petition for the repeal of the NMED GHG cap and trade regulation. PNM and the other appellants filed a petition to repeal the New Mexico GHG cap and trade regulation, and in February 2012, the EIB voted unanimously to repeal the GHG cap and trade regulation. The NMED supported the repeal of its GHG cap and trade regulation. The repeal of the GHG cap and trade regulation has now been challenged by two environmental advocacy organizations and is currently pending before the New Mexico Court of Appeals.

80

In a separate rulemaking proceeding filed in December 2008, New Energy Economy (“NEE”) petitioned the EIB for the adoption of a regulation that would cap GHG from larger sources such as electric generation units. The EIB adopted the NEE GHG regulation, in a modified form, in December 2010 as a “backstop” to the NMED GHG cap and trade regulation. The effective date of the NEE GHG regulation was delayed until the later of January 1, 2013 or six months after NMED's cap-and-trade regulation described above is no longer in force. Under the NEE GHG regulation, covered sources would have to reduce GHG emissions by 3% per year, subject to a specified cost cap.

The NEE GHG regulation was challenged in the New Mexico Court of Appeals by PNM and the same groups that challenged the NMED cap and trade regulation. Again, during the pendency of the appeals, the EIB agreed to consider a petition for the repeal of the NEE GHG regulation. In March 2012, the EIB voted unanimously to repeal the NEE GHG regulation. The NMED supported the repeal of the NEE GHG regulation. The repeal of the NEE GHG regulation has been challenged in the Court of Appeals by the same environmental organizations that have challenged the repeal of the NMED cap and trade regulation.

The Court of Appeals conditionally dismissed the challenges to the adoption of the NMED GHG cap and trade and NEE GHG regulations because of the repeal of those regulations. The challenges are subject to reinstatement in the event of a successful challenge to the repeal of the NMED GHG cap and trade or NEE GHG regulation and reinstatement of either of those regulations.

At present it is difficult to assess whether the pending challenges to the repeals of the NMED GHG cap and trade regulation and the NEE GHG regulation will be successful. PNM's analysis of these regulations is that both would increase environmental compliance costs for its fossil fueled generation facilities. It appears that New Mexico is reassessing whether a single-state or regional approach to the regulation of GHG is appropriate public policy. New Mexico is no longer a member-participant in the WCI, but remains involved as an observer. However, PNM cannot rule out future state legislative or regulatory initiatives to regulate GHGs.

On August 2, 2012, thirty-three New Mexico organizations representing public health, business, environmental, consumers, Native American and other interested parties filed a petition for rulemaking with the NMPRC. The petition asks the NMPRC to issue a NOPR regarding the implementation of an Optional Clean Energy Standard for electric utilities located in New Mexico. The proposed standard would have utilities that elect to participate reduce their CO₂ emissions by 3% per year. Utilities that opt into the program would be assured recovery of their reasonable compliance costs. On October 4, 2012, the NMPRC held a workshop to discuss the proposed standard and whether it has authority to proceed with the NOPR. There has been no further action on this matter and it remains pending before the NMPRC.

Transmission Issues

    At any given time, FERC has various notices of inquiry and rulemaking dockets related to transmission issues pending. Such actions may lead to changes in FERC administrative rules or ratemaking policy, but have no time frame in which action must be taken or a docket closed with no further action. Further, such notices and rulemaking dockets do not apply strictly to PNM, but will have industry-wide effects in that they will apply to all FERC-regulated entities. PNM monitors and often submits comments taking a position in such notices and rulemaking dockets or may join in larger group responses. PNM often cannot determine the full impact of a proposed rule and policy change until the final determination is made by FERC and PNM is unable to predict the outcome of these matters.

On November 24, 2009, FERC issued Order 729 approving two Modeling, Data, and Analysis Reliability Standards (“Reliability Standards”) submitted by NERC – MOD-001-1 (Available Transmission System Capability) and MOD-029-1 (Rated System Path Methodology). Both MOD-001-1 and MOD-029-1 require a consistent approach, provided for in the Reliability Standards, to measuring the total transmission capability (“TTC”) of a transmission path. The TTC level established using the two Reliability Standards could result in a reduction in the available transmission capacity currently used by PNM to deliver generation resources necessary for its jurisdictional load and for fulfilling its obligations to third-party users of the PNM transmission system.

During the first quarter of 2011, at the request of PNM and other southwestern utilities, NERC advised all transmission owners and transmission service providers that the implementation of portions of the MOD-029 methodology for "Flow Limited" paths has been delayed until such time as a modification to the standard can be developed that will mitigate the technical concerns identified by the transmission owners and transmission service providers. PNM and other western utilities filed a Standards Action Request with NERC in the second quarter of 2012 and are waiting for the request to be processed through NERC's standards development.

81

In July 2011, FERC issued Order 1000 adopting new requirements for transmission planning, cost allocation, and development.  Order 1000 calls for significant changes to the transmission process of WestConnect, an organization of utility companies providing transmission of electricity, in the western region that includes PNM.  On October 11, 2012, PNM and other WestConnect participants filed modified versions of Attachment K to their transmission tariffs to meet Order 1000 regional compliance requirements. Thirteen intervention motions were filed, with several objecting to and/or protesting various provisions of the filings submitted by the WestConnect participants. On December 17, 2012, the WestConnect participants filed responses to the issues raised by the intervenors. On March 21, 2013, FERC issued its order regarding PNM's and six other WestConnect FERC jurisdictional utilities compliance filings. FERC partially accepted many aspects of the filings including the governance structure that gives the transmission owners a veto authority over the regional plan and cost allocations. A major change directed by FERC is the requirement that the cost allocations be binding on identified beneficiaries and that a process be created that will result in a qualified developer being selected. WestConnect members are evaluating the order and will be required to submit revised filings. The non-binding cost allocation was of particular importance to the non-public utility members of WestConnect. These entities are evaluating how, and if, they can participate in regional planning given that this directive is something they cannot accept. Compliance filings must be made by July 22, 2013. Another compliance filing will be made in July 2013 to address the planning and cost allocation between WestConnect and other regions.

Financial Reform Legislation

The Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Reform Act”), enacted in July 2010, includes provisions that will require certain over-the-counter derivatives, or swaps, to be centrally cleared and executed through an exchange or other approved trading facility. It also includes provisions related to swap transaction reporting and recordkeeping and may impose margin requirements on swaps that are not centrally cleared. The United States Commodity Futures Trading Commission ("CFTC") has published final rules defining several key terms related to the act and has set compliance dates for various types of market participants. The Dodd-Frank Reform Act provides exemptions from certain requirements, including an exception to the mandatory clearing and swap facility execution requirements for commercial end-users that use swaps to hedge or mitigate commercial risk. PNM expects to qualify for this exception. PNM also expects to be able to comply with its requirements under the Dodd-Frank Reform Act and related rules within the time frames required by the CFTC. However, as a result of the Dodd-Frank Reform Act and related rules, PNM's swap activities could be subject to increased costs, including from higher margin requirements. In addition, implementation of, and compliance with, the swaps provisions of the Dodd-Frank Reform Act and related rules by PNM's swap counterparties could result in increased costs. At this time, PNM cannot predict the ultimate impact the Dodd-Frank Reform Act may have on PNM's financial condition, results of operations, cash flows, or liquidity.

Other Matters

On March 25, 2013, a petition was filed by IBEW Local 66 with the National Labor Relations Board seeking to certify a union at TNMP for utility workers. On April 12, 2013, a second petition was filed by IBEW Local 66 with the National Labor Relations Board seeking to certify a union at TNMP of meter technicians, who were not included in the original petition. Approximately 200 employees are covered by the petitions. Elections to determine whether the IBEW will represent the employees will be held in May 2013.  Should the employees vote to unionize, contract negotiations will begin immediately with the union.

See Notes 9 and 10 herein and Notes 16 and 17 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K for a discussion of commitments and contingencies and rate and regulatory matters.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of financial statements in accordance with GAAP requires Company management to select and apply accounting policies that best provide the framework to report the results of operations and financial position for PNMR, PNM, and TNMP. The selection and application of those policies requires management to make difficult, subjective, and/or complex judgments concerning reported amounts of revenue and expenses during the reporting period and the reported amounts of assets and liabilities at the date of the financial statements. As a result, there exists the likelihood that materially different amounts would be reported under different conditions or using different assumptions.

As of March 31, 2013, there have been no significant changes with regard to the critical accounting policies disclosed in PNMR’s, PNM’s, and TNMP’s 2012 Annual Reports on Forms 10-K. The policies disclosed included unbilled revenues, regulatory accounting, impairments, decommissioning costs, derivatives, pension and other postretirement benefits, accounting for contingencies, income taxes, and market risk.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company manages the scope of its various forms of risk through a comprehensive set of policies and procedures with oversight by senior level management through the RMC. The Board’s Finance Committee sets the risk limit parameters. The RMC has oversight over the risk control organization. The RMC is assigned responsibility for establishing and enforcing the policies, procedures and limits and evaluating the risks inherent in proposed transactions on an enterprise-wide basis. The RMC's responsibilities include:

• Establishment of policies regarding risk exposure levels and activities in each of the business segments

• Approval of the types of derivatives entered into for hedging

• Review and approval of hedging risk activities

84

• Establishment of policies regarding counterparty exposure and limits

• Authorization and delegation of transaction limits

• Review and approval of controls and procedures for derivative activities

• Review and approval of models and assumptions used to calculate mark-to-market and market risk exposure

• Proposing risk limits to the Board’s Finance Committee for its approval

• Quarterly reporting to the Board’s Audit and Finance Committees on these activities.

To the extent an open position exists, fluctuating commodity prices, interest rates, equity prices, and economic conditions can impact financial results and financial position, either favorably or unfavorably. As a result, the Company cannot predict with

certainty the impact that its risk management decisions may have on its businesses, operating results, or financial position.

Commodity Risk

Information concerning accounting for derivatives and the risks associated with commodity contracts is set forth in Note 4, including a summary of the fair values of mark-to-market energy related derivative contracts included in the Condensed Consolidated Balance Sheets. During the three months ended March 31, 2013 and the year ended December 31, 2012, PNMR and PNM had no commodity derivative instruments designated as cash flow hedging instruments.

Commodity contracts that meet the definition of a derivative under GAAP, other than those derivatives designated as normal purchases and normal sales, are recorded at fair value on the Condensed Consolidated Balance Sheets. The following table details the changes in PNMR’s net asset or liability balance sheet position for mark-to-market energy transactions:

PNM measures the market risk of its long-term contracts and wholesale activities using a Monte Carlo VaR simulation model to report the possible loss in value from price movements and is not a measure of the potential accounting mark-to-market loss. The quantitative risk information is limited by the parameters established in creating the model. The Monte Carlo VaR methodology employs the following critical parameters: historical volatility estimates, market values of all contractual commitments, a three-day holding period, seasonally adjusted and cross-commodity correlation estimates, and a 95% confidence

85

level. The instruments being evaluated may trigger a potential loss in excess of calculated amounts if changes in commodity prices exceed the confidence level of the model used.

PNM measures VaR for the positions in its wholesale portfolio that are not covered by a FPPAC. For the three months ended March 31, 2013, the high, low, and average VaR amounts were $1.2 million, $0.6 million, and $0.9 million. For the year ended December 31, 2012, the high, low, and average VaR amounts were $1.4 million, $0.3 million, and $0.6 million. At March 31, 2013 and December 31, 2012, the VaR amounts for the PNM wholesale portfolio were $1.2 million and $0.5 million.

The VaR limits, which were not exceeded during the three months ended March 31, 2013 or the year ended December 31, 2012, represent an estimate of the potential gains or losses that could be recognized on the Company’s portfolios, subject to market risk, given current volatility in the market, and are not necessarily indicative of actual results that may occur, since actual future gains and losses will differ from those estimated. Actual gains and losses may differ due to actual fluctuations in market prices, operating exposures, and the timing thereof, as well as changes to the underlying portfolios during the year.

Credit Risk

The Company is exposed to credit risk from its retail and wholesale customers, as well as counterparties to derivative instruments. The Company conducts counterparty risk analysis across business segments and uses a credit management process to assess the financial conditions of counterparties.

The following table provides information related to PNMR’s credit exposure by the credit worthiness (credit rating) and concentration of credit risk for counterparties to derivative transactions. All credit exposures at March 31, 2013 will mature in less than two years.

Schedule of Credit Risk Exposure

March 31, 2013

Rating (1)	Credit Risk Exposure(2)		Number of Counter-parties >10%	Net Exposure of Counter-parties >10%
	(Dollars in thousands)
External ratings:
Investment grade	$	5,735	2	$	5,345
Non-investment grade	134		—	—
Split ratings	116
Internal ratings:
Investment grade	866		—	—
Non-investment grade	493		—	—
Total	$	7,344		$	5,345

⁽¹⁾  The rating “Investment Grade” is for counterparties, or a guarantor, with a minimum S&P rating of BBB- or Moody's rating of Baa3. The category “Internal Ratings - Investment Grade” includes those counterparties that are internally rated as investment grade in accordance with the guidelines established in the Company’s credit policy.

⁽²⁾  The Credit Risk Exposure is the gross credit exposure, including long-term contracts (other than firm-requirements wholesale customers), forward sales, and short-term sales. The exposure captures the amounts from receivables/payables for realized transactions, delivered and unbilled revenues, and mark-to-market gains/losses. Gross exposures can be offset according to legally enforceable netting arrangements but are not reduced by posted credit collateral. At March 31, 2013, PNMR held no credit collateral to offset its credit exposure.

The Company provides for losses due to market and credit risk. Net credit risk for the Company’s largest counterparty as of March 31, 2013 was $6.2 million, which is due from a firm-requirements wholesale customer.

The PVNGS lessor notes are not exposed to credit risk, since the notes are repaid as PNM makes payments on the underlying leases. Other investments have no significant counterparty credit risk.

86

Interest Rate Risk

The majority of the Company’s long-term debt is fixed-rate debt and does not expose earnings to a major risk of loss due to adverse changes in market interest rates. However, the fair value of PNMR’s consolidated long-term debt instruments would increase by 2.5%, or $48.9 million, if interest rates were to decline by 50 basis points from their levels at March 31, 2013. In general, an increase in fair value would impact earnings and cash flows to the extent not recoverable in rates if all or a portion of debt instruments were acquired in the open market prior to their maturity. TNMP has long-term debt of $50.0 million that bears interest at a variable rate. However, TNMP has also entered into a hedging arrangement that effectively results in this debt bearing interest at a fixed rate, thereby eliminating interest rate risk. At May 1, 2013, PNMR, PNM, and TNMP had $60.3 million, $16.2 million, and $30.0 million of short term debt outstanding under their revolving credit facilities, which allow for a maximum aggregate borrowing capacity of $300.0 million for PNMR, $400.0 million for PNM, and $75.0 million for TNMP. These facilities bear interest at variable rates, which averaged 1.70% for PNMR, 1.45% for PNM, and 1.83% for TNMP on May 1, 2013 borrowings. At May 1, 2013, PNMR had outstanding borrowings of $100.0 million under the PNMR Term Loan Agreement and PNM had outstanding borrowings of $75.0 million under the PNM Term Loan Agreement. The term loans bear interest at variable rates, which were 1.325% for PNMR and 1.45% for PNM at May 1, 2013. The Company is exposed to interest rate risk to the extent of future increases in variable interest rates.

The investments held by PNM in trusts for decommissioning and reclamation had an estimated fair value of $201.4 million at March 31, 2013, of which 45.8% were fixed-rate debt securities that subject PNM to risk of loss of fair value with movements in market interest rates. If interest rates were to increase by 50 basis points from their levels at March 31, 2013, the decrease in the fair value of the fixed-rate securities would be 2.5%, or $2.3 million.

PNM does not directly recover or return through rates any losses or gains on the securities, including equity investments discussed below, in the trusts for nuclear decommissioning and reclamation. However, the overall performance of these trusts does enter into the periodic determinations of expense and funding levels, which are factored into the ratemaking process to the extent applicable to regulated operations. PNM is at risk for shortfalls in funding of obligations due to investment losses, including those from the equity market risks discussed below to the extent not ultimately recovered through rates charged to customers.

Equity Market Risk

The NDT and the trust for post-term reclamation of the coal mines serving SJGS hold certain equity securities at March 31, 2013. These equity securities expose PNM to losses in fair value should the market values of the underlying securities decline. At March 31, 2013, these equity securities were valued at $105.3 million. A hypothetical 10% decrease in equity prices would reduce the fair values of these funds by $10.5 million.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures

As of the end of the period covered by this quarterly report, each of PNMR, PNM, and TNMP conducted an evaluation under the supervision and with the participation of its management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Based upon this evaluation, the Chief Executive Officer and the Chief Financial Officer of each of PNMR, PNM, and TNMP concluded that the disclosure controls and procedures are effective.

Changes in internal controls

There have been no changes in each of PNMR’s, PNM's, and TNMP's internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) during the quarter ended March 31, 2013 that have materially affected, or are reasonably likely to materially affect, each of PNMR’s, PNM's, and TNMP's internal control over financial reporting.

Exhibit 10.1

PNM RESOURCES, INC.

2013 OFFICER ANNUAL INCENTIVE PLAN

Introduction

PNM Resources, Inc. (the “Company”) has adopted this 2013 Officer Annual Incentive Plan (the “Plan”) for the purpose of providing annual cash-based incentive awards (each an “Award”) to eligible Officers (as defined below). The Awards payable to Officers under the Plan are intended to qualify as Performance Cash Awards granted pursuant to Section 9.4 of the PNM Resources, Inc. Second Amended and Restated Omnibus Performance Equity Plan (the “PEP”). In the case of Officers who are Covered Employees as defined in the PEP, the Awards also are intended to qualify as Performance-Based Awards granted pursuant to Section 12 of the PEP.

Capitalized terms used in the PEP and not otherwise defined in this Plan document have the meanings given to them in the PEP.

Eligibility

All Officers of the Company and its Affiliates are eligible to participate in the Plan. For purposes of the Plan, the term “Officer” means any employee who has the title of Chief Executive Officer, Chief Operating Officer, President, Executive Vice President, Senior Vice President or Vice President and who is in salary grade H18 or higher.

Award Determinations in General

Awards are based on the Incentive Earnings Per Share (“EPS”) levels for the Performance Period as set forth in Table 1 of Attachment A, the weighting between Corporate and Business Area goals as described in Table 2 of Attachment A and Award levels achieved during the Performance Period as described in Table 3 of Attachment A. The Performance Period began on January 1, 2013 and will end on December 31, 2013.

An Officer’s Award will equal the Officer’s share of the Incentive EPS Award Pool described below. If the Officer’s share of the appropriate Performance Award Pool described below is less than the Officer’s share of the Incentive EPS Award Pool, however, the Officer will receive the smaller amount.

An Officer’s share of an Award Pool will be based upon the amount potentially payable to the Officer for the attained level of performance (Threshold, Target or Maximum), as determined in accordance with Table 3 of Attachment A, as compared to the aggregate amounts potentially payable for the attained level of performance to all of the Officers who are entitled to share in that Award Pool. In determining the amount potentially payable to an Officer, the base salaries will be determined as of January 1, 2013. In no event will the amount payable to an Officer exceed the indicated percentage of the Officer’s base salary for the attained performance level as set forth in Table 3 of Attachment A. In addition, in no event will the amount payable to one Officer be increased due to a decrease in the amount payable to any other Officer.

Incentive EPS Award Pool

In order for any Awards to be payable to eligible Officers, the Company must achieve the Threshold EPS level set forth in Table 1 of Attachment A. If the Company does not achieve the Threshold EPS level (calculated before any charges for amounts due pursuant to this Plan), no Awards are payable under the Plan to any Officer. If the Company achieves the Threshold EPS level (calculated before any charges for amounts due pursuant to this Plan), but the charges for amounts due pursuant to this Plan reduce the Incentive EPS to an amount below the Threshold EPS level, the Committee, in the exercise of its discretion, may either pay no Awards or may reduce the Threshold level Incentive EPS Award Pool by the amount necessary to assure that the Incentive EPS is equal to the Threshold level Incentive EPS.

If the Threshold, Target or Maximum EPS levels, as listed in Table 1, are achieved, the aggregate potential Awards payable to the Officers at that level of performance (e.g., the aggregate level of Awards payable at Threshold, Target or Maximum as shown in Table 3 of Attachment A) will make up the “Incentive EPS Award Pool.” If the actual EPS exceeds the minimum level for a performance level by at least $0.01, but is less than the maximum level for that performance level (e.g., if the actual EPS exceeds $1.32 but is less than $1.37), the EPS Award Pool will be increased by using straight-line interpolation between the size of the EPS Award Pool based on the attained level (e.g., Threshold) and the size of the Incentive EPS Award Pool at the next higher level (e.g., Target). The Compensation and Human Resources Committee (the “Committee”) of the Company’s Board of Directors (the “Board”) has the discretion to increase the Incentive EPS Award Pool by an amount less than the amount determined by using straight-line interpolation. The EPS Award Pool is capped by the aggregate Maximum Awards shown in Table 3 for all eligible Officers.

Performance Award Pools

A Corporate Goals Scorecard and Business Area Scorecards listing each performance measure established by the Committee will be maintained by the PNM Resources, Inc. Management Systems Group. As set forth in Table 2 of Attachment A, the performance of the Chief Executive Officer and the Senior Officers (the Chief Operating Officer, the Executive Vice President and the Senior Vice Presidents) are measured 100% on the Corporate Goals Scorecard. Vice Presidents are measured 60% on the Corporate Goals Scorecard and 40% on the Business Area Goals Scorecard.

The “Performance Award Pool” for each Business Area is the amount that could be paid in the aggregate to the Vice Presidents assigned to that Business Area based on performance alone, determined by using the following multi-step process:

a) Select the Scorecard results from the appropriate Corporate Goal and Business Area Scorecards;

b) Then multiply each result by the appropriate weighting for the Scorecard as set forth in Table 2 of Attachment A;

c) Then multiply the total Vice President salaries for that Business Area by the Target Award Level as set forth in Table 3 of Attachment A;

2

d) Then multiply the result of each Scorecard (Step b), expressed as a percentage of Target, by the aggregate base salaries of the Vice Presidents included in that Business Area (Step c); and

e) Sum the results for the Vice President participants.

The Performance Award Pool for the CEO and the Senior Officers will be constructed by using the same process but will be based solely upon the Corporate Goals Scorecard.

Award Approval and Payout Timing

In February 2014, the Committee will determine and certify the level of Awards, if any, payable for the Performance Period in the manner described above. The final Awards calculation and recommendation to the Committee by management will be reviewed and certified by the Vice-President, Human Resources; Director, Audit Services; Director, Management Systems group; and Corporate Controller, respectively. The Board then will approve the CEO’s Award and the Committee will approve the Awards for all other Officers. To the extent Awards are payable under the Plan, the Company will make the payment on or before March 15, 2014 in a single lump sum cash payment subject to applicable withholding.

The Committee reserves the discretion to reduce the amount payable to any Officer for such reasons as the Committee determines to be appropriate.

Provisions for a Change in Control

If a Change in Control occurs during the Performance Period and the Officer remains employed by the Company or an Affiliate at the end of the Performance Period, the Officer may be entitled to receive an Award for the Performance Period as determined in accordance with the provisions of this Plan. If the Plan is modified after the occurrence of a Change in Control in a manner that has the effect of reducing the amounts otherwise payable under the Plan, an Officer who remains employed by the Company or an Affiliate at the end of the Performance Period will receive, at a minimum, an Award equal to 50% of the Maximum Award available under this Plan for the Performance Period.

If an Officer terminates employment with the Company or an Affiliate during the Performance Period due to a Qualifying Change in Control Termination, the Officer may be entitled to receive a special payment pursuant to the PNM Resources, Inc. Officer Retention Plan in lieu of any payments under this Plan.

Pro-rata Awards for Partial Service Periods

In certain circumstances (as set forth below) Officers may or may not be eligible for a Pro-rata Award under the Plan.

The following Officers may be eligible for a Pro-rata Award:

- Officers who are newly hired during the Performance Period and are employed by the Company or an Affiliate on the day on which Awards are distributed for the Performance Period.

3

- Employees or Officers who are promoted, transferred or demoted during the Performance Period and are employed by the Company or an Affiliate on the day on which Awards are distributed for the Performance Period.

- Officers who are on leave of absence for any full months during the Performance Period and are employed by the Company or an Affiliate on the day on which Awards are distributed for the Performance Period.

- Officers who terminate employment with the Company or an Affiliate during the Performance Period due to Impaction (as defined in the PNM Resources, Inc. Non-Union Severance Pay Plan), Retirement on or after the Officer’s Normal Retirement Date, or Disability (as defined in the PNM Resources Executive Savings Plan II).

- Officers who die during the Performance Period, in which case the Award will be paid to the spouse of a married Officer, including a same sex spouse, or the estate of an unmarried Officer.

The following Officers are not eligible for any Award, including a Pro-rata Award:

- Officers who terminate employment with the Company or an Affiliate on or before the date on which Awards are distributed for the Performance Period for any reason other than death, Impaction, Retirement, or Disability. As noted above, Officers who terminate employment with the Company or an Affiliate during the Performance Period due to a Qualifying Change in Control Termination may be entitled to receive a special payment pursuant to the PNM Resources, Inc. Officer Retention Plan in lieu of any payments under this Plan.

- Officers who elect voluntary separation or Retirement in lieu of termination for performance or misconduct.

If an Officer is eligible for a Pro-rata Award, it will be calculated based on the number of full months that the Officer was actively employed at each eligibility level during the Performance Period compared to the number of full months included in the Performance Period. (Note: Only months in which the Officer is actively employed on the payroll on the first and last day of the month will count as a full month.) Any Pro-rata Awards to which an Officer becomes eligible pursuant to this paragraph will be paid to the Officer in a single lump sum cash payment subject to applicable withholding on or before March 15, 2014.

Ethics

The purpose of the Plan is to fairly reward performance achievement. Any Officer who manipulates or attempts to manipulate the Plan for personal gain at the expense of customers, shareholders, other employees, or the Company or its Affiliates will be subject to disciplinary action, up to and including termination of employment, and will forfeit and be ineligible to receive any Award under the Plan.

Continuation of Employment

4

This Plan does not confer upon any Officer any right to continue in the employment of the Company or any Affiliate and does not limit the right of the Company or any Affiliate, in its sole discretion, to terminate the employment of any Officer at any time, or in accordance with any written employment agreement the Company and Officer may have.

Amendments

The Committee, in its sole discretion, reserves the right to adjust, amend or suspend the Plan during the Performance Period.

Performance Periods

• The Performance Period began on January 1, 2013 and will end on December 31, 2015.

Performance Goals

• The number of Performance Shares that an officer will receive for the Performance Period will depend on the Company’s level of attainment of a Relative TSR Goal and a FFO/Debt Ratio Goal.

• These Goals and the corresponding Awards are described in the Performance Goal Table (Attachment A).

Performance Share Award Opportunities

• The Company’s level of attainment (Threshold, Target or Maximum) of the Relative TSR and FFO/Debt Ratio Goals determines the level (Threshold, Target or Maximum) of the officer’s Performance Share Awards.

• An officer’s Performance Share Award opportunities also will vary depending on the officer’s position and the officer’s base salary, all as determined in accordance with the Performance Share Award Opportunity Table (Attachment B).

• For purposes of determining the number of Performance Shares to which an officer is entitled at any particular Award Level, the value of one Performance Share shall be equal to the Fair Market Value of one share of the Company’s Stock on the relevant Grant Date and the officer’s base salary shall equal the officer’s base salary as of the first day of the Performance Period.

Time-Vested Restricted Stock Rights Award Opportunities

• At the end of the Performance Period (generally between the next following January 1 and March 15), the Committee will consider whether to grant time-vested Restricted Stock Rights Awards to the participating officers.

• If the Committee, with the approval of the Company’s Board of Directors (the “Board”), decides to make a time-vested Restricted Stock Rights Award to a particular officer, it must adopt a written resolution to that effect. In the resolution, the Committee will establish the Grant Date for the Awards.

• An officer’s time-vested Restricted Stock Rights Award opportunity will vary depending on the officer’s position and the officer’s base salary, all as determined in accordance with the attached Time-Vested RSR Award Opportunity Table (Attachment C). The Committee reserves the discretion to grant an Award that is less than the opportunity set forth in the Table or to grant no time-vested Restricted Stock Rights Award to a particular officer.

• For purposes of determining the number of RSRs to which an officer will be entitled, the value of one RSR shall be equal to the Fair Market Value of one share of the Company’s Stock on the Grant Date specified in the Committee’s resolution and the officer’s base salary shall equal the officer’s base salary on the Grant Date.

Other Provisions

• Only Company officers who have a salary grade of H18 or higher will receive Awards.

• All of the Awards will be made pursuant to the PNM Resources, Inc. Second Amended and Restated Omnibus Performance Equity Plan (the “PEP”).

• All of the Awards will be subject to the standard Terms and Conditions attached hereto as Attachment D.

• The Grant Date for the Performance Share Awards is March 6, 2013, (the first trading day after expiration of the current black-out period, as determined in accordance with the Company’s Equity Compensation Awards Policy).

• A pro rated Performance Share Award will be provided to an officer who Separates from Service in the second half of the Performance Period (in other words, between July 1, 2014 and December 31, 2015) due to death, Disability, Retirement or Impaction. A pro rated Award will not be paid to an officer who Separates from Service for any of these reasons during the first half of the Performance Period or to an officer who Separates from Service for any other reason prior to the last day of the Performance Period.

• The pro rated Award will be calculated at the end of the Performance Period based on actual performance during the Performance Period. The proration will be made based on the number of full months of service completed by the officer during the Performance Period, using the proration rules described in Section 13.1(a)(iv)(2) of the PEP. The pro rated Award then will be paid at the same time as Awards are paid to other participants in the Plan.

• If an individual becomes an officer during a Performance Period, the Committee may grant a pro rata Award to the new officer on such terms and conditions as the Committee deems to be appropriate.

• All Performance Share Awards payable to officers who are Covered Employees for the Company’s tax year that coincides with the end of the Performance Period are intended to qualify as Performance-Based Awards granted pursuant to Section 12 of the PEP. As a result, all such Awards are subject to the requirements of Section 12 of the PEP.

By signing below, the undersigned officer of PNM Resources, Inc. hereby certifies that the PNM Resources, Inc. 2013 Long-Term Incentive Plan, as set forth above, was approved by the Compensation and Human Resources Committee of the Board of Directors of PNM Resources, Inc. at its meeting on February 27, 2013.

Performance Goal Table

Goal	Threshold Level1	Target Level	Maximum Level2
Relative TSR3 If the Company’s Relative TSR for the Performance Period places it in the Threshold, Target or Maximum Level range shown to the right, the Officer will be entitled to receive 60% of the Threshold, Target or Maximum Award as determined in accordance with the Award Opportunity Table.	Greater than the 35th percentile but not greater than the 50th percentile.	Greater than the 50th percentile but not greater than the 95th percentile.	Greater than the 95th percentile.
FFO/Debt Ratio4 If the Company’s FFO/Debt Ratio on the last day of the Performance Period places it in the Threshold, Target or Maximum Level range for the Performance Period, the officer will be entitled to receive 40% of the Threshold, Target or Maximum Award as determined in accordance with the Award Opportunity Table.	At least 17.3% but less than 17.8%	At least 17.8% but less than 19.8%	At least 19.8%

^{______________________________________}  

¹If the Company's Relative TSR or FFO/Debt Ratio falls between two Award levels (e.g., the Threshold Level and the Target Level shown in the Performance Goal Table), the number of Performance Shares to which an Officer is entitled will be interpolated between the two Award levels in accordance with uniform procedures prescribed by the Committee.

²In no event will an Officer receive more than the Maximum Award for an Officer of his or her level as listed in the Award Opportunity Table.

³The “Relative TSR” Goal refers to the Company's “Total Shareholder Return” for the Performance Period (expressed as a percentage of the “Beginning Stock Price,” as defined below) as compared to the “Total Shareholder Return” of the other utilities included in the S & P 400 Mid-Cap Utility Index. For this purpose, the Total Shareholder Return of the Company and the other utilities included in the Index will be determined by adding any dividends paid by the Company (or such other utilities) to the appreciation in the value of the Company's Stock (or the other utilities' common stock). The appreciation shall be measured by comparing the “Beginning Stock Price” and “Ending Stock Price.” The “Beginning Stock Price” is the average closing price of the Company's Stock (or the common stock of the other utilities) on the 20 trading days immediately preceding the first day of the Performance Period. The “Ending Stock Price” is the average closing price of the Company's Stock (or the common stock of the other utilities) on the last 20 trading days of the Performance Period.

⁴ Equals PNMR's funds from operations for the fiscal year ending December 31, 2015, divided by PNMR's total debt outstanding (including any long-term leases and unfunded pension plan obligations) as of December 31, 2015.  Funds from operations are equal to the amount of PNMR's net cash flow from operating activities (as reflected on the Consolidated Statement of Cash Flows) as reported in the Company's Form 10-K for PNM Resources adjusted by the following items:  (1) adding amounts received by PNMR as principal payments on the Palo Verde lessor notes, (2) including amounts attributable to principal payments on imputed debt from long-term leases, (3) excluding changes in PNMR's working capital, including bad debt expense, (4) excluding the impacts of the Valencia Energy Facility consolidation, (5) subtracting the amount of capitalized interest, and (6) excluding any contributions to the PNM or TNMP qualified pension plans.  The calculation is consistent with Moody's calculation of FFO/Debt.

Pursuant to the PEP, the Company’s Compensation and Human Resources Committee (the “Committee”) has developed the PNM Resources, Inc. 2013 Long-Term Incentive Plan (the “Plan” or the “2013 Plan”) pursuant to which eligible officers may receive Performance Share Awards and time-vested Restricted Stock Rights Awards.

All of the Awards granted under the 2013 Plan are made pursuant to the PEP and are subject to the provisions of the PEP. In addition, all of the Awards under the 2013 Plan are made subject to these Terms and Conditions. All of the terms of the PEP are incorporated into this document by reference. Capitalized terms used in but not otherwise defined in this document shall have the meanings given to them in the PEP.

1.    Performance Share Awards.

(a)    Determination of Relative TSR and FFO/Debt Ratio. The Committee will determine the Relative TSR and FFO/Debt Ratio for the Performance Period and the officer’s corresponding Performance Share Award, if any, within 60 days following the end of the Performance Period. The Committee then will certify and submit its determinations with respect to the Relative TSR and FFO/Debt Ratio and the number of Performance Shares to which an officer is entitled to the Board of Directors for review and approval. The Performance Shares to which an officer is entitled shall become payable at the times described below.

(b)    Separation from Service; Forfeiture. Unless an officer qualifies for a pro rated Award as a result of the officer’s Separation from Service during the second half of the Performance Period due to death, Disability, Retirement, or Impaction, as described in the Plan, the officer’s Award will be forfeited upon the officer’s Separation from Service prior to the end of the Performance Period. If the Company terminates an officer’s employment for Cause during or following the expiration of the Performance Period, all vested and unvested Performance Shares shall be canceled and forfeited immediately, regardless of whether the officer elects Retirement.

(c)    Form and Timing of Delivery of Stock. All of the Performance Shares awarded and vested pursuant to the Plan will be paid in Stock within the first 90 days of the calendar year following the end of the Performance Period. The Performance Shares granted under this Plan are subject to the requirements of Section 409A of the Code. Accordingly, the restrictions described in Section 20.3 of the PEP apply to the Performance Shares.

2.    Time-Vested Restricted Stock Rights Awards.

(a)    Vesting.

on March 7, 2017; (ii) an additional 34% of the time-vested Restricted Stock Rights will vest on March 7, 2018; and (iii) the final 33% of the time-vested Restricted Stock Rights will vest on March 7, 2019.

(2)    Upon an officer’s involuntary or voluntary Separation from Service for any reason other than those set forth in Section 2(a)(3), the time-vested Restricted Stock Rights, if not previously vested, shall be canceled and forfeited immediately.

(3)    Upon an officer’s Separation from Service due to death, Disability, Retirement, Impaction or a Qualifying Change in Control Termination, any unvested time-vested Restricted Stock Rights shall become 100% vested in accordance with the applicable provisions of the PEP.

(b)    Form and Timing of Delivery of Certificate. All of the time-vested Restricted Stock Rights awarded pursuant to this Plan will be paid in Stock in accordance with the following provisions:

(2)    If any time-vested Restricted Stock Rights vest in accordance with Section 2(a)(3), the officer will receive the Stock payable with respect to such Restricted Stock Rights within 90 days following the date of the officer’s Separation from Service.

(3)    If the 90‑day period during which payments may be made pursuant to Section 2(a)(1) or (3) begins in one calendar year and ends in another, the officer will receive the Stock in the second calendar year.

(4)    All Stock will be awarded in accordance with the requirements of Section 409A of the Code and Section 20.3 of the PEP.

3.    Adjustments.

4.    Dividend Equivalents. An officer will not be entitled to receive a dividend equivalent for any of the Performance Shares or time-vested Restricted Stock Rights granted under the Plan.

Pursuant to Section 18.1 of the PEP, the Company has concluded that an officer shall be required to satisfy federal, state, and local income tax withholding and employment tax requirements on any Award made pursuant to the Plan by directing the sale of a sufficient number of the shares acquired upon payment of the Award to cover the minimum withholding requirements, by means of the mandatory withholding of a number of shares

D-2

sufficient to satisfy such requirements, or by such other means as the Company may direct from time to time.

6.    Status of Plan and Administration. The Plan and these Terms and Conditions shall at all times be subject to the terms and conditions of the PEP and shall in all respects be administered by the Committee in accordance with the terms of and as provided in the PEP. The Committee shall have the sole and complete discretion with respect to the interpretation of the Plan, these Terms and Conditions and the PEP, and all matters reserved to it by the PEP.

1  Earnings (loss) from continuing operations before income taxes and non-controlling interest for the year ended December 31, 2011 includes a pre-tax loss of $21.4 million due to the write-off of regulatory disallowances at PNM and TNMP.

Earnings (loss) from continuing operations before income taxes and non-controlling interest includes a pre-tax loss of $188.2 million due to the impairment of PNMR's investment in an equity investee.

Accounting Policies [Abstract]

Significant Accounting Policies and Responsibility for Financial Statements

Significant Accounting Policies and Responsibility for Financial Statements

Financial Statement Preparation

In the opinion of management, the accompanying unaudited interim Condensed Consolidated Financial Statements reflect all normal and recurring accruals and adjustments that are necessary to present fairly the consolidated financial position at March 31, 2013 and December 31, 2012, and the consolidated results of operations, comprehensive income, and consolidated cash flows for the three months ended March 31, 2013 and 2012. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could ultimately differ from those estimated. The Notes to Condensed Consolidated Financial Statements include disclosures for PNMR, PNM, and TNMP. This report uses the term “Company” when discussing matters of common applicability to PNMR, PNM, and TNMP. Discussions regarding only PNMR, PNM, or TNMP are so indicated. Certain amounts in the 2012 Condensed Consolidated Financial Statements and Notes thereto have been reclassified to conform to the 2013 financial statement presentation.

These Condensed Consolidated Financial Statements are unaudited. Certain information and note disclosures normally included in the annual Consolidated Financial Statements have been condensed or omitted, as permitted under the applicable rules and regulations. Readers of these financial statements should refer to PNMR’s, PNM’s, and TNMP’s audited Consolidated Financial Statements and Notes thereto that are included in their respective 2012 Annual Reports on Form 10-K. Weather causes the Company’s results of operations to be seasonal in nature and the results of operations presented in the accompanying Condensed Consolidated Financial Statements are not necessarily representative of operations for an entire year.

GAAP defines subsequent events as events or transactions that occur after the balance sheet date but before financial statements are issued or are available to be issued. Based on their nature, magnitude, and timing, certain subsequent events may be required to be reflected at the balance sheet date and/or required to be disclosed in the financial statements. The Company has evaluated subsequent events as required by GAAP.

Principles of Consolidation

The Condensed Consolidated Financial Statements of each of PNMR, PNM, and TNMP include their accounts and those of subsidiaries in which that entity owns a majority voting interest. PNM also consolidates the PVNGS Capital Trust and Valencia. PNM owns undivided interests in several jointly-owned power plants and records its pro-rata share of the assets, liabilities, and expenses for those plants.

PNMR shared services' administrative and general expenses, which represent costs that are primarily driven by corporate level activities, are charged to the business segments at cost. Other significant intercompany transactions between PNMR, PNM, and TNMP include interest and income tax sharing payments, as well as dividends paid on common stock. All intercompany transactions and balances have been eliminated. See Note 11.

Significant Accounting Policies and Responsibility for Financial Statements (Policies)

3 Months Ended

Mar. 31, 2013

Accounting Policies [Abstract]

Principles of Consolidation

The Condensed Consolidated Financial Statements of each of PNMR, PNM, and TNMP include their accounts and those of subsidiaries in which that entity owns a majority voting interest. PNM also consolidates the PVNGS Capital Trust and Valencia. PNM owns undivided interests in several jointly-owned power plants and records its pro-rata share of the assets, liabilities, and expenses for those plants.

PNMR shared services' administrative and general expenses, which represent costs that are primarily driven by corporate level activities, are charged to the business segments at cost. Other significant intercompany transactions between PNMR, PNM, and TNMP include interest and income tax sharing payments, as well as dividends paid on common stock. All intercompany transactions and balances have been eliminated. See Note 11.

Segment Reporting

The following segment presentation is based on the methodology that management uses for making operating decisions and assessing performance of its various business activities. A reconciliation of the segment presentation to the GAAP financial statements is provided.

Variable Interest Entity

GAAP determines how an enterprise evaluates and accounts for its involvement with variable interest entities, including determining the primary beneficiary of a variable interest entity, by focusing primarily on whether the enterprise has the power to direct the activities that most significantly impact the economic performance of a variable interest entity. GAAP also requires continual reassessment of the primary beneficiary of a variable interest entity.

Commitments and Contingencies

Commitments and Contingencies

Overview

There are various claims and lawsuits pending against the Company. The Company is also subject to federal, state, and local environmental laws and regulations and periodically participates in the investigation and remediation of various sites. In addition, the Company occasionally enters into financial commitments in connection with its business operations. The Company is also involved in various legal and regulatory (Note 10) proceedings in the normal course of its business. It is not possible at this time for the Company to determine fully the effect of all litigation and other legal and regulatory proceedings on its financial position, results of operations, or cash flows.

With respect to some of the items listed below, the Company has determined that a loss is not probable or that, to the extent probable, cannot be reasonably estimated. In some cases, the Company is not able to predict with any degree of certainty the range of possible loss that could be incurred. Notwithstanding these facts, the Company has assessed these matters based on current information and made judgments concerning their potential outcome, giving due consideration to the nature of the claim, the amount and nature of damages sought, and the probability of success. Such judgments are made with the understanding that the outcome of any litigation, investigation, and other legal proceeding is inherently uncertain. In accordance with GAAP, the Company records liabilities for matters where it is probable a loss has been incurred and the amount of loss is reasonably estimable. The actual outcomes of the items listed below could ultimately differ from the judgments made and the differences could be material. The Company cannot make any assurances that the amount of reserves or potential insurance coverage will be sufficient to cover the cash obligations that might be incurred as a result of litigation or regulatory proceedings. The Company does not expect that any known lawsuits, environmental costs, and commitments will have a material effect on its financial condition, results of operations, or cash flows.

Additional information concerning commitments and contingencies is contained in Note 16 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Commitments and Contingencies Related to the Environment

Nuclear Spent Fuel and Waste Disposal

Nuclear power plant operators are required to enter into spent fuel disposal contracts with the DOE that require the DOE to accept and dispose of all spent nuclear fuel and other high-level radioactive wastes generated by domestic power reactors. Although the Nuclear Waste Policy Act required the DOE to develop a permanent repository for the storage and disposal of spent nuclear fuel by 1998, the DOE announced that it would not be able to open the repository by 1998 and sought to excuse its performance under the contract. In November 1997, the D.C. Circuit issued a decision preventing the DOE from excusing its own delay, but refused to order the DOE to begin accepting spent nuclear fuel. Based on this decision and the DOE's delay, a number of utilities, including APS (on behalf of itself and the other PVNGS owners, including PNM), filed damages actions against the DOE in the Court of Federal Claims. The PVNGS owners previously received a damages award for costs incurred through December 2006. APS filed a subsequent lawsuit, on behalf of itself and the other PVNGS owners, against DOE in the Court of Federal Claims on December 19, 2012. The lawsuit alleges that from January 1, 2007, through June 30, 2011, APS, as a co-owner of PVNGS, incurred additional damages due to DOE's continuing failure to remove spent nuclear fuel and high level waste from PVNGS. PNM is unable to predict the outcome of this matter. PNM estimates that it will incur approximately $42.8 million (in 2010 dollars) for its share of the costs related to the on-site interim storage of spent nuclear fuel at PVNGS during the term of the operating licenses. PNM accrues these costs as a component of fuel expense as the fuel is consumed. At March 31, 2013 and December 31, 2012, PNM had a liability for interim storage costs of $12.6 million and $13.9 million included in other deferred credits.

On June 8, 2012, the D.C. Circuit issued its decision on a challenge by several states and environmental groups of the NRC's rulemaking regarding temporary storage and permanent disposal of high-level nuclear waste and spent nuclear fuel. The petitioners had challenged the NRC's 2010 update to the agency's Waste Confidence Decision. The D.C. Circuit found that the agency's 2010 Waste Confidence Decision update constituted a major federal action, which requires either an environmental impact statement or a finding of no significant impact from the agency's actions. The D.C. Circuit found that the NRC's evaluation of the environmental risks from spent nuclear was deficient, and therefore remanded the 2010 Waste Confidence Decision update for further action. In September 2012, the NRC issued a directive to its staff to proceed with development of a generic environmental impact statement to support an updated Waste Confidence Decision within 24 months. PNM is unable to predict the impact that the decision may have on the operation of PVNGS.

The Clean Air Act

Regional Haze

In 1999, EPA developed a regional haze program and regional haze rules under the CAA. The rule directs each of the 50 states to address regional haze. Pursuant to the CAA, states have the primary role to regulate visibility requirements by promulgating SIPs. States are required to establish goals for improving visibility in national parks and wilderness areas (also known as Class I areas) and to develop long-term strategies for reducing emissions of air pollutants that cause visibility impairment in their own states and for preventing degradation in other states. States must establish a series of interim goals to ensure continued progress. The first planning period specifies setting reasonable progress goals for improving visibility in Class I areas by the year 2018. In July 2005, the EPA promulgated its final regional haze rule guidelines for states to conduct BART determinations for certain covered facilities, including utility boilers, built between 1962 and 1977 that have the potential to emit more than 250 tons per year of visibility impairing pollution. If it is demonstrated that the emissions from these sources cause or contribute to visibility impairment in any Class I area, then BART must be installed by 2018.

SJGS

SJGS is a source that is subject to the statutory obligations of the CAA to reduce visibility impacts. The State of New Mexico submitted its SIP on the regional haze and interstate transport elements of the visibility rules for review by EPA in June 2011. The SIP found that BART to reduce NOx emissions from SJGS is selective non-catalytic reduction technology (“SNCR”). Nevertheless, in August 2011, EPA published its FIP, stating that it was required to do so by virtue of a consent decree it had entered into with an environmental group in litigation concerning the interstate transport requirements of the CAA. The FIP included a regional haze BART determination for SJGS that requires installation of selective catalytic reduction technology (“SCR”) with stringent NOx emission limits on all four units by September 21, 2016.

PNM, the Governor of New Mexico, and NMED petitioned the Tenth Circuit to review EPA's decision and requested EPA to reconsider its decision. The Tenth Circuit denied petitions to stay the effective date of the rule on March 1, 2012. These parties have also formally asked EPA to stay the effective date of the rule. Several environmental groups have intervened in support of EPA. WEG also filed an action to challenge EPA's rule in the Tenth Circuit, seeking to shorten its compliance period from five years to three years and PNM has intervened in this action. Oral arguments on the merits of the FIP challenges were held in October 2012 in the Tenth Circuit. In accordance with the court's order, the parties have filed supplemental information. No decision has been announced and there is no deadline for a court decision.

In litigation involving several environmental groups, the United States District Court for the District of Columbia entered a consent decree, which, as amended, required EPA to issue a final rulemaking on New Mexico's regional haze SIP by November 15, 2012. EPA approved all components of the SIP, except for the NOx BART determination for SJGS. With respect to that element of the SIP, EPA determined that with the FIP in place, it had met its obligation under the consent decree.

Because the unchanged compliance deadline of the FIP required PNM to continue to take steps to commence installation of SCRs at SJGS, PNM entered into a contract in October 2012 with an engineering, procurement, and construction contractor to install SCRs on behalf of the SJGS owners. The construction contract, which includes termination provisions in the event that SCRs are determined in the future to be unnecessary, has been suspended through November 1, 2014. PNM estimated the total cost to install SCRs on all four units of SJGS to be between approximately $824 million and $910 million, which amounts include costs for construction management, gross receipts taxes, AFUDC, and other PNM costs, although final costs would be refined through an “open book” subcontractor bidding process. The costs for the project to install SCRs would encompass installation of technology to comply with the NAAQS requirements described below.

PNM previously indicated it estimated the cost of SNCRs on all four units of SJGS to be between approximately $85 million and $90 million based on a conceptual design study. Along with the SNCR installation, additional equipment would be required to be installed to meet the NAAQS requirements described below, the cost of which had been estimated to total between approximately $105 million and $110 million for all four units of SJGS. The estimates for SNCRs and the NAAQS requirements include gross receipts taxes, AFUDC, and other PNM costs.

Based upon its current SJGS ownership interest, PNM's share of the costs under either SCRs or SNCRs as described above would be about 46.3%.

During 2012 and early 2013, PNM engaged in discussions with NMED and EPA regarding an alternative to the FIP and SIP. On February 15, 2013, PNM, NMED, and EPA agreed to pursue a revised plan that could provide a new BART path to comply with federal visibility rules at SJGS. The terms of the non-binding agreement would result in the retirement of SJGS Units 2 and 3 by the end of 2017 and the installation of SNCRs on Units 1 and 4 by the later of January 31, 2016 or 15 months after EPA approval of a revised SIP. Under this plan, NMED would develop a revised SIP and submit it to the EIB for approval. Upon approval by EIB, the revised SIP would be submitted to EPA for approval. EIB approval is projected for the fourth quarter of 2013, with EPA action in late 2014.

NMPRC approval of the retirement of SJGS Units 2 and 3 and plans for PNM to acquire power to replace its reduced capacity from SJGS would also be part of implementation. PNM also anticipates requesting approval to recover from ratepayers the unrecovered investment in SJGS Units 2 and 3 and costs incurred to retire those units. At March 31, 2013, PNM's net book value of SJGS Units 2 and 3 was approximately $290 million.

Contemporaneously with the signing of the non-binding agreement, EPA indicated in writing that if the terms agreed to do not move forward due to circumstances outside of the control of PNM and NMED, EPA will work with the state and PNM to create a reasonable FIP compliance schedule to reflect the time used to develop the new state plan. PNM is also exploring potential additional areas of relief, including relief from the Tenth Circuit.

In connection with the implementation of the plan, retirement of SJGS Units 2 and 3 could result in shifts in ownership among SJGS owners as may be agreed upon by the owners, including PNM acquiring additional ownership in SJGS Unit 4. Owners of the affected units also may seek approvals of their utility commissions or governing boards.

This plan primarily focuses on how SJGS would meet the regional haze rule, but also indicates that PNM would build a natural gas-fired generating plant to be sited at SJGS to partially replace the capacity from the retired coal units. Detailed replacement power strategies also would be finalized.  PNM believes adequate replacement power alternatives will be available to meet its generation needs and ensure reliability.

On February 25, 2013, the parties filed their status reports with the Tenth Circuit.  To demonstrate that progress has been made toward settling the Tenth Circuit litigation, information, including the non-binding agreement and its accompanying timeline, was submitted to the Tenth Circuit. Following the parties' submission of their status reports, on February 28, 2013, the Tenth Circuit referred the litigation to the Tenth Circuit Mediation Office, which has authority to require the parties to attend mediation conferences to informally resolve issues in the pending appeals.

On April 1, 2013, PNM submitted a new BART analysis to the NMED reflecting the terms of the non-binding agreement including the installation of SNCRs on Units 1 and 4 and the retirement of Units 2 and 3. NMED is currently preparing a new proposed SIP for BART.

If the February 15, 2013 plan described above is implemented, PNM currently estimates its share of the costs to install SNCRs and the additional equipment to comply with NAAQS requirements on SJGS Units 1 and 4 would be approximately $63 million, including gross receipts taxes, AFUDC, and other PNM costs. This amount is based on the anticipation that PNM's ownership share of SJGS Units 1 and 4 would aggregate to approximately 52%. PNM also estimates that the cost of replacing a portion of PNM's share of the reduction in generating capacity due to the retirement of SJGS Units 2 and 3 with identified gas-fired peaking capacity would be approximately $280 million. Neither of these amounts is included in PNM's current construction expenditure forecast since approval of the plan is subject to numerous conditions. Additional base load generating capacity may be required to replace a portion of retired SJGS capacity. Although the nature of additional base load capacity has not yet been identified, it could come from PVNGS Unit 3 or additional gas-fired generation. Operating costs would also increase with the installation of either SCRs or SNCRs.

PNM can provide no assurance that the requirements of the plan agreed to on February 15, 2013 will be accomplished at all or within the required timeframes. If the February 15, 2013 plan is not implemented, PNM would seek to work with NMED and EPA to develop a revised timetable for implementation of the FIP. If an agreement on a revised timetable cannot be reached, PNM will likely be unable to complete the installation of SCRs on all four units at SJGS by the FIP deadline of September 21, 2016. In such event, PNM would likely seek relief from the compliance deadline from EPA or the Tenth Circuit in order to continue to be able to operate the plant during the completion of the installation process. If relief is not granted, PNM could be forced to temporarily cease operation of some or all of the SJGS units. If a shutdown was required, PNM would then have to acquire temporary replacement power through short-term or open-market purchases in order to serve the needs of its customers. There can be no assurance that sufficient replacement power will be available to serve PNM's needs or, if available, what costs would be incurred.

PNM is unable to predict the ultimate outcome of these matters or what additional pollution control equipment will be required at SJGS.PNM will seek recovery from its ratepayers for all costs that may be incurred as a result of the CAA requirements. Although the additional equipment and other final requirements will result in additional capital and operating costs being incurred, PNM believes that its access to the capital markets is sufficient to be able to finance the installation. It is possible that requirements to comply with the CAA, combined with the financial impact of possible future climate change regulation or legislation, if any, other environmental regulations, the result of litigation, and other business considerations, could jeopardize the economic viability of SJGS or the ability of individual participants to continue participation in the plant.

Four Corners

On August 6, 2012, the EPA issued its final BART determination for Four Corners. The rule includes two compliance alternatives. The first emission control strategy finalized by the EPA would require the installation of post-combustion controls, including SCRs, on each of Units 1-5 at Four Corners to reduce NOx emissions. Under the second emission control alternative, the owners of Four Corners would have the option to close permanently Units 1-3 by January 1, 2014 and install SCR post-combustion NOx controls on each of Units 4 and 5 by July 31, 2018. For particulate matter emissions, EPA is requiring Units 4 and 5 to meet an emission limit of 0.015 lb/MMBTU and the plant to meet a 20% opacity limit, both of which are achievable through operation of the existing baghouses. Although unrelated to BART, the final BART rule also imposes a 20% opacity limitation on certain fugitive dust emissions from Four Corners' coal and material handling operations. The Four Corners participants have until July 1, 2013 to notify the EPA of which emission control strategy Four Corners will follow.

The Four Corners participants' obligations to comply with EPA's final BART determinations, coupled with the financial impact of possible future climate change regulation or legislation, other environmental regulations, and other business considerations, could jeopardize the economic viability of Four Corners or the ability of individual participants to continue their participation in Four Corners.

PNM is continuing to evaluate the impacts of EPA's BART determination for Four Corners. PNM estimates its share of costs, including PNM's AFUDC, to be up to approximately $75 million for post-combustion controls at Four Corners Units 4 and 5. PNM would seek recovery from its ratepayers of all costs that are ultimately incurred. PNM has no ownership interest in Four Corners Units 1, 2, and 3. PNM is unable to predict the ultimate outcome of this matter.

SCE, a participant in Four Corners, has indicated that certain California legislation may prohibit it from making emission control expenditures at Four Corners. APS and SCE entered into an asset purchase agreement, providing for the purchase by APS of SCE's 48% interest in each of Units 4 and 5 of Four Corners. The principal remaining condition to closing is the negotiation and execution of a new coal supply contract for Four Corners on terms reasonably acceptable to APS. See Coal Supply below. APS has announced that, if APS's purchase of SCE's interests in Units 4 and 5 at Four Corners is consummated, it will shutdown Units 1, 2, and 3 at the plant.

Four Corners BART FIP Challenge

On October 22, 2012, WEG filed a petition for review in the Ninth Circuit challenging the Four Corners BART FIP.  In its petition, WEG alleges that the final BART rule results in more air pollution being emitted into the air than allowed by law and that EPA failed to follow the requirements of the ESA.  APS intervened in this matter and filed a motion to dismiss this lawsuit for lack of jurisdiction or alternatively to transfer the lawsuit to the Tenth Circuit. On February 25, 2013, the Ninth Circuit denied APS' motion to dismiss, but granted the request to transfer the case to the Tenth Circuit. PNM cannot currently predict the outcome of this matter or the range of its potential impact.

Regional Haze Challenges

On December 27, 2012, WEG filed a petition for review in the Tenth Circuit challenging the SO₂ and particulate matter emissions elements of EPA's approval of New Mexico's Regional Haze SIP.  PNM intervened in this matter. PNM is continuing to evaluate the impacts of WEG's challenge to EPA's approval of this SIP.

On February 26, 2013, HEAL Utah and other environmental groups filed petitions in the Tenth Circuit challenging EPA's final approval of the remaining elements of New Mexico's Regional Haze SIP, as well as EPA's approval of the Albuquerque/Bernalillo County Air Quality Control Board SIP.  

PNM was granted intervention in both matters. On May 3, 2013, the Tenth Circuit ordered the parties to file consolidated briefing in the WEG and HEAL Utah matters due to the similarity of the WEG and HEAL Utah petitions.  PNM is unable to predict the ultimate outcome of these matters.

SJGS Operating Permit Challenge

On February 16, 2012, EPA issued its response to a WEG petition objecting to SJGS's operating permit granted by the NMED in January 2011. In its order, EPA required NMED to provide clarification on several of the matters raised by WEG.  EPA's order in this matter does not constitute a finding that the plant has violated any provision of the CAA or that it has violated any emission limits. 

In August 2012, NMED issued a response to the EPA order stating that SJGS's operating permit would be reopened to make certain modifications to the permit. NMED issued a public notice regarding proposed modifications to the SJGS operating permit on September 19, 2012 and issued a revised operating permit on November 26, 2012. The revised permit includes changes to the SO₂ and particulate matter emission limits that were previously incorporated into the SJGS NSR permit. In addition, the revised permit requires PNM to submit a compliance plan to address carbon monoxide (“CO”) emissions increases at SJGS Unit 2. The compliance plan must be submitted in May 2013 and requires that SJGS submit either a PSD permit application including BACT analysis for CO emissions from Unit 2 or a PSD avoidance permit application that limits net CO emissions increases below the CO PSD threshold of 100 tons per year. PNM is preparing a compliance plan, but does not believe it will have a material impact.

National Ambient Air Quality Standards (“NAAQS”)

The CAA requires EPA to set NAAQS for pollutants considered harmful to public health and the environment. EPA has set NAAQS for certain pollutants, including NOx, SO₂,ozone, and particulate matter. In 2010, EPA updated the primary NOx and SO₂ NAAQS to include a 1-hour maximum standard while retaining the annual standards for NOx and SO₂ and the 24-hour SO₂ standard. New Mexico is in attainment for the 1-hour NOx NAAQS. EPA has issued draft guidance on how to determine whether areas in a state comply with the new 1-hour SO₂ NAAQS and announced that it will publish further guidance or initiate rulemaking on these matters.  Although the determination process has not been finalized, PNM believes that compliance with the 1-hour SO₂ standard may require operational changes and/or equipment modifications at SJGS. On April 6, 2012, PNM filed an application for an amendment to its air permit for SJGS, which would be required for the installation of either SCRs or SNCRs described above. In addition, this application included a proposal by PNM to install equipment modifications for the purpose of reducing fugitive emissions, including NOx, SO₂, and particulate matter. These modifications would help SJGS meet the NAAQS. It is anticipated that this technology would be installed at the same time as the installation of regional haze BART controls, in order to most efficiently and cost effectively conduct construction activities at SJGS. The cost of this technology is dependent upon the type of control technology that is ultimately determined to be NOx BART at SJGS. See Regional Haze - SJGS above.

EPA finalized revisions to its NAAQS for fine particulate matter on December 14, 2012. PNM is currently evaluating the impact of the revised standard on SJGS and its operations.

In January 2010, EPA announced it would strengthen the 8-hour ozone standard by setting a new standard in a range of 0.060-0.070 parts per million. Work is underway to reconsider the ozone standard, with proposed revisions expected in the fall of 2013 and a final standard published by the end of 2014.  Depending upon where the standard for ozone is set, San Juan County, where SJGS is situated, could be designated as not attaining the standard for ozone. If that were to occur, NMED would have responsibility for bringing the county into compliance and would look at all sources of NOx and volatile organic compounds since these are the pollutants that form ground-level ozone. As a result, SJGS could be required to install further NOx controls to meet a new ozone NAAQS. In addition, other counties in New Mexico, including Bernalillo County, may be designated as non-attainment. PNM cannot predict the outcome of this matter, the impact of other potential environmental mitigations, or if additional NOx controls would be required as a result of ozone non-attainment designation.

Citizen Suit Under the Clean Air Act

The operations of SJGS are covered by a Consent Decree with the Grand Canyon Trust and Sierra Club and with the NMED that includes stipulated penalties for non-compliance with specified emissions limits. Stipulated penalty amounts are placed in escrow on a quarterly basis pending review of SJGS's emissions performance. In May 2011, PNM entered into an agreement with NMED and the plaintiffs to resolve a dispute over the applicable NOx emission limits under the Consent Decree. Under the agreement, so long as the NOx emissions limits imposed under the EPA FIP and the New Mexico SIP meet a specified emissions limit, and PNM does not challenge these limits, the parties' dispute is deemed settled.

In May 2010, PNM filed a petition with the federal district court seeking a judicial determination on a dispute relating to PNM's mercury controls. NMED and plaintiffs seek to require PNM to implement additional mercury controls. PNM estimates the implementation would increase annual mercury control costs for the entire station, which are currently $0.6 million, to a total of $6.1 million. The court appointed a special master to evaluate the technical arguments in the case and to address the detection and determination limits of the mercury monitors at SJGS and the appropriate brominated activated carbon injection rate that maximizes the reduction of mercury emissions from SJGS.  The special master issued a report indicating he was unable to make a determination on either of these issues.  In September 2012, PNM submitted objections to certain portions of the special master report and requested an evidentiary hearing. Also in September 2012, NMED and plaintiffs filed a motion asking the court to affirm certain findings in the special master report and order PNM to conduct additional mercury testing. PNM cannot predict the outcome of this matter.

Navajo Nation Environmental Issues

Four Corners is located on the Navajo Reservation and is held under an easement granted by the federal government, as well as a lease from the Navajo Nation. The Navajo Acts purport to give the Navajo Nation Environmental Protection Agency authority to promulgate regulations covering air quality, drinking water, and pesticide activities, including those activities that occur at Four Corners. In October 1995, the Four Corners participants filed a lawsuit in the District Court of the Navajo Nation challenging the applicability of the Navajo Acts to Four Corners. In May 2005, APS and the Navajo Nation signed an agreement resolving the dispute regarding the Navajo Nation's authority to adopt operating permit regulations under the Navajo Nation Air Pollution Prevention and Control Act. As a result of this agreement, APS sought, and the courts granted, dismissal of the pending litigation in the Navajo Nation Supreme Court and the Navajo Nation District Court, to the extent the claims relate to the CAA. The agreement does not address or resolve any dispute relating to other aspects of the Navajo Acts. The Company cannot currently predict the outcome of these matters or the range of their potential impacts.

Section 114 Request

In April 2009, APS received a request from EPA under Section 114 of the CAA seeking detailed information regarding projects at and operations of Four Corners. EPA has taken the position that many utilities have made physical or operational changes at their plants that should have triggered additional regulatory requirements under the NSR provisions of the CAA. APS has responded to EPA's request. PNM is currently unable to predict the timing or content of EPA's response, if any, or any resulting actions.

Four Corners Clean Air Act Lawsuit

In October 2011, Earthjustice, on behalf of several environmental organizations, filed a lawsuit in the United States District Court for the District of New Mexico against APS and the other Four Corners participants alleging violations of the NSR provisions of the CAA and NSPS violations. The plaintiffs seek to have the court enjoin operations at Four Corners until APS applies for and obtains any required NSR permits and complies with the NSPS. The plaintiffs further request the court to order the payment of civil penalties, including a beneficial mitigation project. The case is being held in abeyance while the parties seek to negotiate a settlement. On March 30, 2013, upon joint motion of the parties, the court issued an order deeming the motions to dismiss withdrawn without prejudice during pendency of the stay. At such time as the stay is lifted, the Four Corners participants may reinstate their motions to dismiss without risk of default. PNM cannot currently predict the outcome of this matter or the range of its potential impact.

Endangered Species Act

In January 2011, the Center for Biological Diversity, Diné Citizens Against Ruining Our Environment, and San Juan Citizens Alliance filed a lawsuit in the United States District Court for the District of Colorado against the OSM and the DOI, alleging that OSM failed to engage in mandatory ESA consultation with the United States Fish and Wildlife Service prior to authorizing the renewal of an operating permit for the mine that serves Four Corners.  The lawsuit alleges that activities at the mine, including mining and the disposal of coal combustion residue, will adversely affect several endangered species and their critical habitats.  The lawsuit requested the court to vacate and remand the mining permit and enjoin all activities carried out under the permit until OSM has complied with the ESA.  Neither PNM nor APS was a party to the lawsuit. On March 14, 2012, the Court entered an order dismissing the plaintiffs' lawsuit without prejudice. On May 14, 2012, the plaintiffs appealed the Court's order to the Tenth Circuit. PNM cannot currently predict the outcome of this matter or the range of its potential impact.

Cooling Water Intake Structures

EPA issued its proposed cooling water intake structures rule in April 2011, which would provide national standards for certain cooling water intake structures at existing power plants and other facilities under the Clean Water Act to protect fish and other aquatic organisms by minimizing impingement mortality (the capture of aquatic wildlife on intake structures or against screens) and entrainment mortality (the capture of fish or shellfish in water flow entering and passing through intake structures). The proposed rule would require facilities such as Four Corners and SJGS to either demonstrate that impingement mortality at its cooling water intakes does not exceed a specified rate or reduce the flow at those structures to less than a specified velocity and to take certain protective measures with respect to impinged fish. The proposed rule would also require these facilities to either meet the definition of a closed cycle recirculating cooling system or conduct a “structured site-specific analysis” to determine what site-specific controls, if any, should be required.

The proposed rule would require existing facilities to comply with the impingement mortality requirements as soon as possible, but no later than eight years after the effective date of the rule, and to comply with the entrainment requirements as soon as possible under a schedule of compliance established by the permitting authority. EPA is required to issue a final rule by June 27, 2013. PNM and APS continue to follow the rulemaking and are performing analyses to determine the potential costs of compliance with the proposed rule. PNM is unable to predict the outcome of this matter or a range of the potential costs of compliance.

Effluent Limitation Guidelines

On April 19, 2013, EPA proposed revised effluent limitation guidelines establishing technology-based wastewater discharge limitations for steam electric power plants.  EPA's proposal offers numerous options that target metals and other pollutants in wastewater streams originating from fly ash and bottom ash handling activities, scrubber activities, and non-chemical metal cleaning wastes operations.  EPA is subject to a consent decree deadline to finalize the revised guidelines by May 22, 2014. PNM is in the process of reviewing the pre-publication version of the rule to assess the impact to SJGS and Reeves Station, the only PNM-operated power plants that would be covered by the proposed rule. APS is currently assessing the impact to Four Corners. PNM is unable to predict the outcome of this matter or if it will have a material impact on PNM's financial position, results of operations, or cash flows. 

Santa Fe Generating Station

PNM and the NMED are parties to agreements under which PNM installed a remediation system to treat water from a City of Santa Fe municipal supply well, an extraction well, and monitoring wells to address gasoline contamination in the groundwater at the site of the former Santa Fe Generating Station and service center. PNM believes the observed groundwater contamination originated from off-site sources, but agreed to operate the remediation facilities until the groundwater meets applicable federal and state standards or until the NMED determines that additional remediation is not required, whichever is earlier. The municipal well continues to operate and meets federal drinking water standards. PNM is not able to assess the duration of this project.

The Superfund Oversight Section of the NMED has conducted multiple investigations into the chlorinated solvent plume in the vicinity of the site of the former Santa Fe Generating Station. In February 2008, a NMED site inspection report was submitted to EPA, which states that neither the source nor extent of contamination has been determined and also states that the source may not be the former Santa Fe Generating Station. The NMED investigation is ongoing. In January 2013, NMED notified PNM that monitoring results from April 2012 showed elevated concentrations of nitrate in three monitoring wells and an increase in free-phase hydrocarbons in another well. None of these wells are routinely monitored as part of PNM's obligations under the settlement agreement. PNM is unable to predict the outcome of this matter, but does not believe the former generating station is the source of the nitrates or the increased levels of free-phase hydrocarbons.

Coal Combustion Byproducts Waste Disposal

CCBs consisting of fly ash, bottom ash, and gypsum from SJGS are currently disposed of in the surface mine pits adjacent to the plant. SJGS does not operate any CCB impoundments. The Mining and Minerals Division of the New Mexico Energy, Minerals and Natural Resources Department currently regulates mine placement of ash with federal oversight by the OSM. APS disposes of CCBs in ash ponds and dry storage areas at Four Corners and also sells a portion of its fly ash for beneficial uses, such as a constituent in concrete production.  Ash management at Four Corners is regulated by EPA and the New Mexico State Engineer's Office. 

In June 2010, EPA published a proposed rule that includes two options for waste designation of coal ash. One option is to regulate CCBs as a hazardous waste, which would allow EPA to create a comprehensive federal program for waste management and disposal of CCBs. The other option is to regulate CCBs as a non-hazardous waste, which would provide EPA with the authority to develop performance standards for waste management facilities handling the CCBs and would be enforced primarily by state authorities or through citizen suits. Both options allow for continued use of CCBs in beneficial applications. EPA's proposal does not address the placement of CCBs in surface mine pits for reclamation. An OSM CCB rulemaking team has been formed to develop a proposed rule. 

On April 5, 2012, several environmental groups, including Sierra Club, filed a citizen suit in the D.C. Circuit claiming that EPA has failed to review and revise RCRA's regulations with respect to CCBs. The groups allege that EPA has already determined that revisions to the CCBs regulations are necessary. They also claim that EPA now has a non-discretionary duty to revise the regulations. The environmental groups asked the court to direct EPA to complete its review of the regulation of CCBs and a hazardous waste analytical procedure and to issue necessary revisions of such regulations as soon as possible. Two industry group members subsequently filed separate lawsuits in the D.C. Circuit seeking to ensure that disposal of coal ash would not be regulated as a hazardous waste. The environmental and industry lawsuits have been consolidated.

PNM advocates for the non-hazardous regulation of CCBs. However, if CCBs are ultimately regulated as a hazardous waste, costs could increase significantly. PNM would seek recovery from its ratepayers of all costs that are ultimately incurred. PNM cannot predict the outcome of EPA's or OSM's proposed rulemaking regarding CCB regulation, including mine placement of CCBs, or whether these actions will have a material impact on its operations, financial position, or cash flows. 

Hazardous Air Pollutants (“HAPs”) Rulemaking

In December 2011, the EPA issued its final Mercury and Air Toxics Standards (“MATS”) to reduce emissions of heavy metals, including mercury, arsenic, chromium, and nickel, as well as acid gases, including hydrochloric and hydrofluoric gases, from coal and oil-fired electric generating units with a capacity of at least 25 MW. Existing facilities will generally have up to four years to demonstrate compliance with the new rule. PNM's assessment of MATS indicates that the control equipment currently used at SJGS allows the plant to meet the emission standards set forth in the rule although the plant may be required to install additional monitoring equipment. With regard to mercury, stack testing performed for EPA during the MATS rulemaking process showed that SJGS achieved a mercury removal rate of 99% or greater. APS will conduct testing to determine what additional controls, if any, will be required at Four Corners. If additional controls are required, the costs are not expected to be material.

Other Commitments and Contingencies

Coal Supply

The coal requirements for SJGS are being supplied by SJCC, a wholly owned subsidiary of BHP. In addition to coal delivered to meet the current needs of SJGS, PNM prepays SJCC for certain coal mined but not yet delivered to the plant site. At March 31, 2013 and December 31, 2012, prepayments for coal, which are included in other current assets, amounted to $14.1 million and $9.9 million. These amounts reflect delivery of a portion of the prepaid coal and its utilization due to the mine fire incident described below. SJCC holds certain federal, state, and private coal leases and has an underground coal sales agreement to supply processed coal for operation of SJGS through 2017. Under the coal sales agreement, SJCC is reimbursed for all costs for mining and delivering the coal, including an allocated portion of administrative costs, and receives a return on its investment. BHP Minerals International, Inc. has guaranteed the obligations of SJCC under the coal agreement. The coal agreement contemplates the delivery of coal that would supply substantially all the requirements of SJGS through December 31, 2017.

APS purchases all of Four Corners' coal requirements from a supplier that is also a subsidiary of BHP and has a long-term lease of coal reserves with the Navajo Nation. The Four Corners coal contract runs through July 6, 2016 with pricing determined using an escalating base-price. In December 2012, BHP announced that it has entered into a Memorandum of Understanding with the Navajo Nation setting out the key terms under which the coal mine would be sold to the Navajo Nation. The BHP subsidiary would be retained as the mine manager and operator until July 2016. Key terms of the new coal supply contract are being finalized by the Navajo Nation and the Four Corners owners. As a result of this proposed change in ownership, APS now expects that a new coal supply contract would be executed upon completion of negotiations and following the endorsement of the transfer of ownership to a new Navajo Nation commercial enterprise to be established by the Navajo Nation Tribal Council. On April 29, 2013, the Navajo Nation Tribal Council approved the creation of the new commercial enterprise with sufficient power and authority to execute the transaction with BHP. PNM is unable to predict the outcome of this matter.

In 2010, PNM updated its study of the final reclamation costs for both the surface mines that previously provided coal to SJGS and the current underground mine providing coal and revised its estimates of the final reclamation costs. The estimate for decommissioning the Four Corners mine was also revised in 2010. Based on the most recent estimates, remaining payments for mine reclamation, in future dollars, are estimated to be $59.9 million for the surface mines at both SJGS and Four Corners and $19.7 million for the underground mine at SJGS as of March 31, 2013. At March 31, 2013 and December 31, 2012, liabilities, in current dollars, of $25.9 million and $26.8 million for surface mine reclamation and $4.3 million and $4.2 million for underground mine reclamation were recorded in other deferred credits.

PNM collects a provision for surface and underground mine reclamation costs in its rates. The NMPRC has capped the amount that can be collected from ratepayers for final reclamation of the surface mines at $100.0 million. Previously, PNM recorded a regulatory asset for the $100.0 million and recovers the amortization of this regulatory asset in rates. If future estimates increase the liability for surface mine reclamation, the excess would be expensed at that time.

San Juan Underground Mine Fire Incident

On September 9, 2011, a fire was discovered at the underground mine owned and operated by SJCC that provides coal for SJGS. The federal Mine Safety and Health Administration (“MSHA”) was notified of the incident. On September 12, 2011, SJCC informed PNM that the fire was extinguished. However, MSHA required sealing the incident area and confirmation of a noncombustible environment before allowing re-entry of the sealed area. SJCC regained entry into the sealed area of the mine in early March 2012. On May 4, 2012, SJCC received approval from MSHA and resumed longwall mining operations. If further difficulties occur in the longwall mining operation, PNM and the other owners of SJGS would need to consider alternatives for operating SJGS, including running at less than full capacity or shutting down one or more units, the impacts of which cannot be determined at the current time.

The costs of the mine recovery flowed through the cost-reimbursable component of the coal supply agreement. PNM anticipates that it will recover through its FPPAC the portion of such costs allocable to its customers subject to New Mexico regulation. PNM's filings with the NMPRC reflect an estimate that this incident increased coal costs and the deferral of cost recovery under the FPPAC by $21.6 million. SJCC has submitted an insurance claim regarding the costs it incurred due to the mine fire. Any recovery obtained by SJCC through its insurance carrier may be reimbursable (in whole or in part) to PNM through the coal sales agreement. Any insurance recovery would be flowed through PNM's FPPAC to the extent it relates to increased coal costs included in the FPPAC. The potential impacts of any insurance settlement cannot be determined at the current time. Based on information PNM has received from SJCC to date, PNM does not expect the mine fire to have a material effect on its financial condition, results of operations, or cash flows.

Nuclear Fuel

The PVNGS participants are continually identifying their future nuclear fuel resource needs and negotiating arrangements to fill those needs. In late August 2012, one of PVNGS's suppliers that converts uranium concentrates to uranium hexafluoride invoked the force majeure provision in its contract when it shut down its conversion plant due to regulatory compliance issues. The PVNGS participants have sufficient strategic reserves of enriched uranium such that they do not anticipate a short-term impact on nuclear fuel supplies as a result of the force majeure declaration. The PVNGS participants are evaluating alternate long-term options for securing conversion services.

PVNGS Liability and Insurance Matters

Liability for incidents at nuclear power plants is governed by the Price-Anderson Act, which limits the liability of nuclear reactor owners to the amount of insurance available from both private sources and an industry retrospective payment plan. In accordance with the Price-Anderson Act, the PVNGS participants have insurance for public liability exposure for a nuclear incident totaling $12.6 billion per occurrence. Commercial insurance carriers provide $375 million and $12.2 billion is provided through a mandatory industry wide retrospective assessment program. If losses at any nuclear power plant covered by the program exceed the accumulated funds, PNM could be assessed retrospective premium adjustments. Based on PNM's 10.2% interest in each of the three PVNGS units, PNM's maximum potential assessment per incident for all three units is $36.0 million, with an annual payment limitation of $5.4 million.

The PVNGS participants maintain “all risk” (including nuclear hazards) insurance for damage to, and decontamination of, property at PVNGS in the aggregate amount of $2.75 billion, a substantial portion of which must first be applied to stabilization and decontamination. These coverages are provided by Nuclear Electric Insurance Limited (“NEIL”). Effective April 1, 2013, a sublimit of $1.5 billion for non-nuclear property damage losses has been enacted to the primary policy offered by NEIL. If NEIL's losses in any policy year exceed accumulated funds, PNM is subject to retrospective assessments of $4.3 million for each retrospective assessment declared by NEIL's Board of Directors. The insurance coverages discussed in this and the previous paragraph are subject to policy conditions and exclusions.

Water Supply

Because of New Mexico's arid climate and periodic drought conditions, there is concern in New Mexico about the use of water, including that used for power generation. PNM has secured groundwater rights in connection with the existing plants at Reeves Station, Delta, Afton, Luna, and Lordsburg. Water availability does not appear to be an issue for these plants at this time. However, prolonged drought, ESA activities and a Federal lawsuit by the State of Texas suing the State of New Mexico over water allocations could pose a threat of reduced water availability for these plants.

PNM, APS, and BHP have undertaken activities to secure additional water supplies for SJGS, Four Corners, and related mines to accommodate the possibility of inadequate precipitation in coming years. Since 2004, PNM has entered into agreements for voluntary sharing of the impacts of water shortages with tribes and other water users in the San Juan basin. This agreement has been extended through 2016. In addition, in the case of water shortage, PNM, APS, and BHP have reached agreement with the Jicarilla Apache Nation on a supplemental contract relating to water for SJGS and Four Corners that runs through 2016. Although the Company does not believe that its operations will be materially affected by drought conditions at this time, it cannot forecast the weather or its ramifications, or how policy, regulations, and legislation may impact the Company should water shortages occur in the future.

In April 2010, APS signed an agreement on behalf of the PVNGS participants with five cities to provide cooling water essential to power production at PVNGS for forty years.

PVNGS Water Supply Litigation

In 1986, an action commenced regarding the rights of APS and the other PVNGS participants to the use of groundwater and effluent at PVNGS. APS filed claims that dispute the court's jurisdiction over PVNGS' groundwater rights and their contractual rights to effluent relating to PVNGS and, alternatively, seek confirmation of those rights. In 1999, the Arizona Supreme Court issued a decision finding that certain groundwater rights may be available to the federal government and Indian tribes. In addition, the Arizona Supreme Court issued a decision in 2000 affirming the lower court's criteria for resolving groundwater claims. Litigation on these issues has continued in the trial court. No trial dates have been set in these matters. PNM does not expect that this litigation will have a material impact on its results of operation, financial position, or cash flows.

San Juan River Adjudication

In 1975, the State of New Mexico filed an action in New Mexico District Court to adjudicate all water rights in the San Juan River Stream System, including water used at Four Corners and SJGS. PNM was made a defendant in the litigation in 1976. In March 2009, President Obama signed legislation confirming a 2005 settlement with the Navajo Nation. Under the terms of the settlement agreement, the Navajo water rights would be settled and finally determined by entry by the court of two proposed adjudication decrees.  The court has ordered that settlement of the Navajo Nation's claims under the settlement agreement and entry of the proposed decrees be heard in an expedited proceeding. 

PNM's water rights in the San Juan Basin may be affected by the rights recognized in the settlement agreement as being owned by the Navajo Nation, which comprise a significant portion of water available from sources on the San Juan River and in the San Juan Basin. Therefore, PNM has elected to participate in this proceeding.  The Company is unable to predict the ultimate outcome of this matter or estimate the amount or range of potential loss and cannot determine the effect, if any, of any water rights adjudication on the present arrangements for water at SJGS and Four Corners. Final resolution of the case cannot be expected for several years. An agreement reached with the Navajo Nation in 1985, however, provides that if Four Corners loses a portion of its rights in the adjudication, the Navajo Nation will provide, for an agreed upon cost, sufficient water from its allocation to offset the loss.

Complaint Against Southwestern Public Service Company

In September 2005, PNM filed a complaint under the Federal Power Act against SPS alleging SPS overcharged PNM for deliveries of energy through its fuel cost adjustment clause practices. PNM also intervened in a proceeding brought by other customers raising similar arguments relating to SPS' fuel cost adjustment clause practices (the “Golden Spread proceeding”). In 2008, FERC issued its order in the Golden Spread proceeding affirming that SPS violated its fuel cost adjustment clause tariffs, but shortening the refund period applicable to the violation of the fuel cost adjustment clause issues. PNM and SPS have filed petitions for rehearing and clarification of the scope of the remedies that were ordered and reversal of various rulings in the order. FERC has not yet acted upon the requests for rehearing or clarification and they remain pending further decision. PNM cannot predict the final outcome of the case at FERC or the range of possible outcomes.

Navajo Nation Allottee Matters

A putative class action was filed against PNM and other utilities in February 2009 in the United States District Court in Albuquerque. Plaintiffs claim to be allottees, members of the Navajo Nation, who pursuant to the Dawes Act of 1887, were allotted ownership in land carved out of the Navajo Nation and allege that defendants, including PNM, are rights-of-way grantees with rights-of-way across the allotted lands and are either in trespass or have paid insufficient fees for the grant of rights-of-way or both.  In March 2010, the court ordered that the entirety of the plaintiffs' case be dismissed. The court did not grant plaintiffs leave to amend their complaint, finding that they instead must pursue and exhaust their administrative remedies before seeking redress in federal court.  In May 2010, plaintiffs filed a Notice of Appeal with the Bureau of Indian Affairs ("BIA"), which was denied by the BIA Regional Director. In May 2011, plaintiffs appealed the Regional Director's decision to the DOI Board of Appeals. Briefings on the merits of the appeal are complete and a decision is pending. PNM is participating in order to preserve its interests regarding any PNM-acquired rights-of-way implicated in the appeal. PNM cannot predict the outcome of the proceeding or the range of potential outcomes at this time.

In a separate matter, in September 2012, forty-three landowners claiming to be Navajo allotees filed a notice of appeal with the BIA appealing a March 2011 decision of the BIA Regional Director regarding renewal of a right-of-way for a PNM transmission line. The allotees, many of whom are also allottees in the above matter, generally allege that they were not paid fair market value for the right-of-way, that they were denied the opportunity to make a showing as to their view of fair market value, and thus denied due process. PNM is participating in this matter in order to preserve its interests regarding the right-of-way implicated in the appeal. PNM cannot predict the outcome of the proceeding or the range of potential outcomes at this time.

TGP Complaint

On March 2, 2012, TGP Granada, LLC and its affiliate (collectively, “TGP”) filed a complaint at FERC against PNM and Tortoise Capital Resources Corp. (“TTO”). PNM owns 60% of the EIP and leases the other 40% from TTO. PNM's lease of the portion of the EIP owned by TTO expires on April 1, 2015. The lease provides PNM the option, with 24 months advance notice, of purchasing the leased assets at the end of the lease for fair market value, as well as options to renew the lease.

TGP's filing requested FERC to direct PNM and TTO to identify the party that will immediately assume the obligation of making transmission capacity on the EIP available to customers for use after the April 1, 2015 expiration of the EIP lease agreement. TGP also requested a declaratory order or waiver regarding certain provisions of PNM's Open Access Transmission Tariff to allow its affiliate to change the point-of-receipt associated with a transmission service agreement related to the EIP without losing its transmission service priority. On July 5, 2012, FERC issued an order denying TGP's requests for declaratory order and waiver. In addition, FERC directed PNM, in consultation with TTO, to identify the party that will provide long-term transmission service over the leased portion of the EIP.

On November 1, 2012, PNM and TTO entered into a definitive agreement for PNM to exercise the option to purchase on April 1, 2015 the leased capacity at fair market value, which the parties agreed would be $7.7 million. The lease remains in existence and PNM will record the purchase at the termination of the lease on April 1, 2015. The definitive agreement sets forth the terms and conditions under which PNM would also assume responsibility for scheduling long-term transmission service on the leased capacity. In November 2012, PNM requested the necessary FERC approvals for the definitive agreement. In January 2013, FERC approved PNM's requests. On February 8, 2013, FERC issued an order dismissing as moot a motion filed by TGP for clarification of FERC's July 5, 2012 order. Since no rehearing request or appeal was filed, the February 8, 2013 order is final and non-appealable.

Regulatory and Rate Matters

Regulatory and Rate Matters

Regulatory and Rate Matters

The Company is involved in various regulatory matters, some of which contain contingencies that are subject to the same uncertainties as those described in Note 9. Additional information concerning regulatory and rate matters is contained in Note 17 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

PNM

Renewable Portfolio Standard

The REA establishes a mandatory RPS requiring a utility to acquire a renewable energy portfolio equal to 10% of retail electric sales by 2011, 15% by 2015, and 20% by 2020. The NMPRC requires renewable energy portfolios to be “fully diversified.” Prior to December 2012, the diversity requirements were 20% from wind energy, 20% from solar energy, 10% from other renewable technologies, and 1.5% from distributed generation with the distributed generation component increasing to 3% in 2015. In December 2012, NMPRC issued an order that amended the diversity requirements to 30% wind, 20% solar, 5% other, and 1.5% distributed generation, increasing to 3% in 2015, and adopted other changes to its renewable energy rule, including the increase in the RCT discussed below.

The REA provides for streamlined proceedings for approval of utilities' renewable energy procurement plans, assures utilities recovery of costs incurred consistent with approved procurement plans, and requires the NMPRC to establish a RCT for the procurement of renewable resources to prevent excessive costs being added to rates. The NMPRC had established a RCT for 2011 of 2% of all customers' aggregated overall annual electric charges that increased by 0.25% annually until reaching 3% in 2015. In December 2012, the NMPRC approved an amended RCT set at 3% of customers' annual electric charges beginning in 2013 and continuing thereafter.

In July 2011, PNM filed its renewable energy procurement plan for 2012. The plan requested a variance from the RPS due to RCT limitations. The plan was diversity-compliant based on the reduced RPS, except for non-wind/non-solar resources, which were not available. In December 2011, the NMPRC approved PNM's 2012 plan, but ordered PNM to spend an additional $0.9 million on renewable procurements in 2012. PNM intends to recover the costs of the supplemental procurements through the renewable rider discussed below. The NMPRC also required PNM to file its 2013 renewable energy procurement plan by April 30, 2012. The 2013 plan proposed procurements for 2013 and 2014 of 20 MW of PNM-owned solar PV facilities, at an estimated cost of $45.5 million, wind and solar REC purchases in 2013, and a PPA for the output of a new geothermal facility. The plan also included an additional procurement of 2 MW of PNM-owned solar PV facilities at an estimated cost of $4.5 million to supply the energy sold under PNM's voluntary renewable energy tariff. The plan will enable PNM to comply with the statutory RPS amount in 2013, but requires a variance from the NMPRC's diversity requirements in 2013 while the proposed geothermal facilities are being constructed. This plan had been expected to achieve full RPS quantity and diversity compliance by 2014 without exceeding the RCT. The NMPRC approved the plan in December 2012, but reduced the additional solar PV procurement from 2 MW to 1.5 MW. Construction of the geothermal facility has been delayed due to a longer than expected permitting process. This will delay the in-service date of the geothermal facility until later in 2014. PNM does not believe this delay will affect its ability to comply with the diversity requirements as amended in December 2012.

PNM is recovering certain renewable procurement costs from customers through a rate rider. See Renewable Energy Riderbelow.

Renewable Energy Rider

On August 14, 2012, the NMPRC authorized PNM to recover certain renewable procurement costs through a rate rider on a per KWh basis. The approved rates are $0.0022335 per KWh in 2012 and $0.0028371 per KWh in 2013. The order disapproved the recovery of the cost of a supplemental REC procurement ordered by the NMPRC in the 2012 procurement plan case because the NMPRC had not yet acted on the specific $0.9 million procurement proposed by PNM, which is discussed under Renewable Portfolio Standard above. The NMPRC subsequently approved the supplemental REC procurement, but ordered that a hearing be held on its inclusion in the rider. PNM implemented the rider on August 20, 2012. The rider will terminate upon a final order in PNM's next general rate case unless the NMPRC authorizes PNM to continue it. Amounts collected under the rider are capped at $18.0 million in 2012 and $24.6 million in 2013. Any amounts above the caps are deferred for future recovery without carrying costs. As a separate component of the rider, if PNM's earned return on jurisdictional equity in 2013, adjusted for weather and other items not representative of normal operations, exceeds 10.5%, PNM must refund to customers during May through December 2014 the amount over 10.5%.

In compliance with the NMPRC's  rate rider order, PNM filed a notice to implement a 3.37% increase in the current rider rate effective with May 2013 bills.  The NMPRC suspended the effective date of the new rate for a period of nine months from April 1, 2013 and appointed a Hearing Examiner to conduct a hearing on the proposed change.  The Hearing Examiner recommended approval of the notice. On April 24, 2013, the NMPRC issued an order denying approval of the Hearing Examiner's Recommended Decision but did not disapprove the notice. The costs proposed to be recovered have been previously approved for recovery by the NMPRC. The order did not rescind these prior approvals. The order does not indicate what further proceedings, if any, the NMPRC intends to conduct.  On May 3, 2013, PNM, the NMPRC staff, and an intervening party filed a joint motion  for rehearing of the NMPRC order.

Energy Efficiency and Load Management

Program Costs

Public utilities are required by the Efficient Use of Energy Act to achieve specified levels of energy savings and to obtain NMPRC approval to implement energy efficiency and load management programs. Costs to implement approved programs are recovered through a rate rider. In 2013, this act was amended to set an annual program budget equal to 3% of a utility's annual revenue.

In October 2012, PNM filed an energy efficiency program application for programs to be offered beginning in May 2013. The filing included proposed program costs of $22.5 million plus a proposed profit incentive of $4.2 million and requested that the NMPRC issue an order by April 1, 2013. Portions of the program plan and proposed profit incentive are opposed by other parties to the case. PNM subsequently revised its proposed profit incentive to $2.9 million. A hearing on the application was held in February 2013. PNM is not able to predict the outcome of this matter.

Disincentives/Incentives Adder

The Efficient Use of Energy Act requires the NMPRC to remove utility disincentives to implementing energy efficiency and load management programs and to provide incentives for such programs. A rule approved by the NMPRC authorized electric utilities to collect rate adders of $0.01 per KWh for lifetime energy savings and $10 per KW for demand savings related to energy efficiency and demand response programs beginning in 2010. The NMAG and NMIEC appealed the NMPRC order adopting this rule to the New Mexico Supreme Court. PNM began implementing a rate rider under the rule to collect adders related to its 2010 program savings in December 2010 while the appeal of the rule was pending. In July 2011, the Supreme Court annulled and vacated the order adopting the rule and remanded the matter to the NMPRC. As a result of the Supreme Court decision, PNM filed revised tariffs and ceased collecting this adder for 2010 program savings on August 21, 2011. Of the $4.2 million authorized for recovery, $2.6 million was collected through August 20, 2011.

In June 2011, prior to the Supreme Court decision, the NMPRC approved PNM-specific adders of $0.002 per KWh and $4 per KW for savings due to programs implemented in 2011. PNM is presently collecting $1.3 million in adder revenues consistent with this order. After the Supreme Court decision vacating the rule, the NMPRC initiated a proceeding to determine whether PNM should be required to cease collecting the adders and to refund all adder revenues collected since December 2010. In November 2011, the NMPRC issued orders that PNM is not required to refund any adder revenues and is authorized to continue collecting the adders. However, in an order on rehearing, which it subsequently rescinded, the NMPRC further reduced the amount of the authorized adders. Prior to the rescission, PNM appealed the rehearing order to the Supreme Court. In March 2012, the Supreme Court granted PNM's motion to vacate the rehearing order and dismiss PNM's appeal. In a separate appeal and writ proceeding in the Supreme Court, NMIEC and the NMAG seek to overturn the NMPRC order allowing PNM to continue to collect adders in light of the 2011 Supreme Court decision. On May 21, 2012 the Supreme Court dismissed the writ proceeding. Oral argument in the appeal was held in December 2012, and a decision in the appeal is expected in 2013. PNM is unable to predict the outcome of the appeal.

On March 27, 2013, PNM filed the reconciliation for actual energy efficiency program costs, associated incentives, and actual collections for calendar year 2012. The reconciliation filing showed a net over-recovery of $0.2 million, composed of an over-recovery of $1.0 million of program costs and an under-recovery of incentives of $0.8 million. PNM subsequently revised the estimated incentive under-recovery to $0.5 million. PNM and the NMPRC staff filed a motion seeking to substitute the new reconciliation filing with a proposed effective date of May 28, 2013. On April 24, 2013, the NMPRC issued an order granting the motion. Under the order, the new rate based on the adjusted reconciliation amount will become effective on May 28, 2013, unless suspended by the NMPRC.

Decoupling Rulemaking

On May 15, 2012, the NMPRC issued a NOPR that would have amended the NMPRC's energy efficiency rule to authorize use of a decoupling mechanism to recover certain fixed costs of providing retail electric service from the rates charged on a per KWh of consumption, as the mechanism for removal of disincentives associated with the implementation of energy efficiency programs. The proposed rule also addressed incentives associated with energy efficiency. On July 26, 2012, the NMPRC closed the proposed rulemaking and opened a new energy efficiency rulemaking docket that may address decoupling and incentives. Workshops to develop a proposed rule have been held, but no order proposing a rule has been issued. PNM is unable to predict the outcome of this matter.

2010 Electric Rate Case and FPPAC

An order of the NMPRC approving an amended stipulation in PNM's 2010 Electric Rate Case limits the amount that can be recovered on an annual basis for fuel costs, renewable energy costs, and energy efficiency costs during certain years. Costs in excess of the limits are deferred, without carrying costs, for recovery in future periods. The fuel cost caps are $38.8 million for the FPPAC year beginning July 1, 2012, which PNM began collecting at that time, and $36.2 million for the FPPAC year beginning July 1, 2013. PNM estimates that the caps will result in approximately $45.5 million of FPPAC costs being deferred for future collection at June 30, 2014. Costs attributed to the mine fire incident discussed in Note 9 are included in the FPPAC amounts. Possible recovery of costs through SJCC's insurance, also discussed in Note 9, is not reflected in the FPPAC amounts.

PNM must file an application for continued use of its FPPAC every four years. PNM anticipates making this continuation filing in May 2013.

2011 Integrated Resource Plan

NMPRC rules require that investor owned utilities file an IRP every three years. The IRP is required to cover a 20-year planning period and contain an action plan covering the first four years of that period. In its most recent IRP, which was filed in July 2011, PNM indicated that it planned to meet its anticipated load growth through a combination of new natural gas-fired generating plants, renewable energy resources, load management, and energy efficiency programs. However, PNM has not entered into any commitments regarding these plans beyond what is otherwise described herein. As required by NMPRC rules, PNM utilized a public advisory group process during the development of the 2011 IRP. Two protests were filed to the IRP requesting rejection of the plan. The NMPRC assigned the case to a Hearing Examiner and designated a mediator to facilitate negotiations. The NMPRC staff filed a motion in December 2011 to dismiss the protests and terminate the proceeding on the ground that PNM's IRP fully complies with NMPRC rules. PNM is unable to predict the outcome of this matter.

Emergency FPPAC

In 2008, the NMPRC authorized PNM to implement an Emergency FPPAC from June 2, 2008 through June 30, 2009. The NMPRC order approving the Emergency FPPAC also provided that if PNM's base load generating units did not operate at or above a specified capacity factor and PNM was required to obtain replacement power to serve jurisdictional customers, PNM would be required to make a filing with the NMPRC seeking approval of the replacement power costs. In its required filing, PNM stated that the costs of the replacement power amounting to $8.0 million were prudently incurred and made a motion that they be approved. The NMPRC staff opposed PNM's motion and recommended that PNM be required to refund the amount collected. Auditors selected by the NMPRC found that PNM was prudent in operating its base load units and in securing replacement power but had not obtained prior NMPRC approval in the manner required by the NMPRC order. PNM continues to assert that its recovery of replacement power costs was proper and did not violate the NMPRC's order. The NMPRC has not ruled on this matter. Under the terms of the approved stipulation in the 2010 Electric Rate Case, the parties to the stipulation, including the NMPRC staff, jointly requested that the NMPRC take no further action in this matter and close the docket. No party has opposed that request. Although the NMPRC has not acted on the joint request, the NMPRC electronic docket shows the docket closed. PNM is unable to predict the outcome of this matter.

Applications for Approvals to Purchase Delta

As discussed in Note 9 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K, PNM has entered in to an agreement to purchase Delta, a 132 MW natural gas peaking unit from which PNM currently acquires energy and capacity under a PPA. The agreement to purchase Delta is subject to approvals by the NMPRC and FERC. On January 3, 2013, PNM filed an application with the NMPRC for a Certificate of Convenience and Necessity to own and operate Delta and for a determination of related ratemaking principles and treatment. PNM requested expedited consideration of the application so that a final order could be issued by May 31, 2013. The NMPRC has assigned the matter to a hearing examiner. A hearing on the application is scheduled to begin on May 13, 2013. PNM filed an application for approval of the Delta acquisition at FERC on January 24, 2013. FERC approved the purchase on February 26, 2013. PNM is unable to predict the outcome of this matter.

Application for Approval of La Luz Generating Station

PNM anticipates filing an application for a Certificate of Convenience and Necessity for a new 40 MW gas-fired generating facility near Belen, New Mexico with the NMPRC in May 2013. The application also will ask for a determination of related ratemaking principles and treatment. The estimated cost of this facility is approximately $63.2 million. PNM anticipates an in-service date in the first quarter of 2016. PNM has entered into a contract for the turbine to be used for this project. PNM also has entered into a turn-key contract with an outside contractor for the construction of the generating facility. Both of these contracts allow PNM to cancel the project if NMPRC approval is not obtained. PNM is unable to predict the outcome of this matter.

Transmission Rate Case

In October 2010, PNM filed a notice with FERC to increase its wholesale electric transmission revenues by $11.1 million annually, based on a return on equity of 12.25%. The filing also sought to revise certain Open Access Transmission Tariff provisions and bi-lateral contractual terms.  In December 2010, FERC issued an order accepting PNM's filing and suspending the proposed tariff revisions for five months. The proposed rates were implemented on June 1, 2011, subject to refund. The rate increase applied to all of PNM's wholesale electric transmission service customers, which include other utilities, electric cooperatives, and entities that use PNM's transmission system to transmit power at the wholesale level.  The rate increase did not impact PNM's retail customers. On January 2, 2013, FERC approved an unopposed settlement agreement, which increases transmission service revenues by $2.9 million annually. In addition, the parties agreed that if PNM files for a formula based rate change within one year from FERC's approval of the settlement agreement, no party will oppose the general principle of a formula rate, although the parties may still object to particular aspects of the formula. PNM refunded amounts collected in excess of the settled rates in January 2013. See Tri-State Complaint below.

Formula Transmission Rate Case

On December 31, 2012, PNM filed an application with FERC for authorization to move from charging stated rates for wholesale electric transmission service to a formula rate mechanism pursuant to which rates for wholesale transmission service are calculated annually in accordance with an approved formula. The proposed formula includes updating cost of service components, including investment in plant and operating expenses, based on information contained in PNM's annual financial report filed with FERC, as well as including projected large transmission capital projects to be placed into service in the following year. The projections included are subject to true-up in the following year formula rate. Certain items, including changes to return on equity and depreciation rates, require a separate filing to be made with FERC before being included in the formula rate. The rates resulting from PNM's application are intended to replace the rates approved by the FERC on January 2, 2013 in the transmission rate case discussed above. As filed, PNM's request would result in a $3.2 million wholesale electric transmission rate increase, based on PNM's 2011 data and a 10.81% return on equity, and authority to adjust transmission rates annually based on an approved formula. The proposed $3.2 million rate increase would be in addition to the $2.9 million rate increase approved by the FERC on January 2, 2013 in the transmission rate case discussed above.

On March 1, 2013, FERC issued an order (1) accepting PNM's revisions to its rates for filing and suspending the proposed revisions to become effective August 2, 2013, subject to refund; (2) directing PNM to submit a compliance filing to establish its return-on-equity (“ROE”) using the median, rather than the mid-point, of the ROEs from a proxy group of companies; (3) directing PNM to submit a compliance filing to remove the acquisition adjustment related to PNM's 60% ownership of the EIP transmission line from its rate proposal; and (4) setting the proceeding for hearing and settlement judge procedures. PNM would be allowed to make a separate filing related to recovery of the EIP acquisition adjustment. On April 1, 2013, PNM made the required compliance filing. In addition, PNM filed for rehearing of FERC's order regarding the ROE. On May 1, 2013, PNM provided an updated rate request to its wholesale electric transmission service customers incorporating 2012 data and the FERC order into the formula rate. The updated formula rate would result in a $1.3 million rate increase over the rates approved by FERC on January 2, 2013. PNM anticipates filing the updated rate request with FERC on June 1, 2013. The new rates will apply to all of PNM's wholesale electric transmission service customers, which include other utilities, electric cooperatives, and entities that use PNM's transmission system to transmit power at the wholesale level. The new rates will not apply to PNM's retail customers. PNM is unable to predict the outcome of this proceeding.

Tri-State Complaint

On March 13, 2013, Tri-State filed a complaint with FERC alleging that PNM's existing transmission rates approved by FERC on January 2, 2013 in the transmission rate case discussed above are unjust and unreasonable under the Federal Power Act.  Tri-State's allegations are premised upon FERC's March 1, 2013 order and certain data provided by PNM in PNM's Formula Transmission Rate Case discussed above.  Tri-State seeks a reduction in PNM's annual transmission revenue requirement for the period between March 13, 2013 and the implementation of PNM's proposed rates under the Formula Transmission Rate Case.  Tri-State also requests that FERC consolidate the complaint proceeding with the Formula Transmission Rate Case.  On April 2, 2013, PNM answered Tri-State's complaint, asking FERC to dismiss the complaint and deny Tri-State's request to consolidate the complaint proceeding with the Formula Transmission Rate Case. PNM is unable to predict the outcome of this proceeding.

Firm-Requirements Wholesale Customers

Navopache Electric Cooperative, Inc. Rate Case

In September 2011, PNM filed an unexecuted amended sales agreement between PNM and NEC with FERC. The agreement proposed a cost of service based rate for the electric service and ancillary services PNM provides to NEC, which would result in an annual increase of $8.7 million or a 39.8% increase over existing rates. PNM also requested a FPPAC and full recovery of certain third-party transmission charges PNM incurs to serve NEC. NEC filed a protest to PNM's filing with FERC. In November 2011, FERC issued an order accepting the filing, suspending the effective date to be effective April 14, 2012, subject to refund, and set the proceeding for settlement. The parties finalized a settlement agreement and PNM filed for the necessary FERC approval on December 6, 2012. The settlement agreement would result in an annual increase of $5.3 million, an extension of the contract for 10 years, and an agreement that PNM will be able to file an application for formula based rates to be effective in 2015. On April 5, 2013, FERC approved the settlement agreement. PNM anticipates refunding amounts collected in excess of the settled rates by June 4, 2013.

City of Gallup, New Mexico Contract Approval Case

PNM provides both energy and power services to Gallup, PNM's second largest firm-requirements wholesale customer, under an electric service agreement that expires June 30, 2013. On May 1, 2013, PNM and Gallup agreed to extend the term of the agreement to June 30, 2014 and to increase the demand and energy rates under the agreement. On May 1, 2013, PNM requested FERC approval of the amended agreement to be effective July 1, 2013. If approved by FERC, revenue from Gallup would increase by $3.1 million during the term of the amended agreement. PNM is unable to predict the outcome of this proceeding.

TNMP

Advanced Meter System Deployment and Surcharge Request

In July 2011, the PUCT approved a settlement and authorized an AMS deployment plan that permits TNMP to collect $113.3 million in deployment costs through a surcharge over a 12-year period. TNMP began collecting the surcharge on August 11, 2011. Deployment of advanced meters began in September 2011 and is scheduled to be completed over a 5-year period. In February 2012, the PUCT opened a proceeding to consider the feasibility of an “opt-out” program for retail consumers that wish to decline receipt of an advanced meter. The PUCT has requested comments and convened a public meeting to hear various issues. No proposal or decision has yet been announced by the PUCT. However, various individuals filed a petition with the PUCT seeking a moratorium on any advanced meter deployment. The PUCT denied the petition and an appeal was filed with the Texas District Court on September 28, 2012. On February 21, 2013, the PUCT filed a proposed rule to permit customers to opt-out of the AMS deployment. A hearing to receive additional comment on the proposed rulemaking was held on April 19, 2013. Any opt-out program would apply to all transmission and distribution utilities in ERCOT. TNMP cannot predict the outcome or effect of this proceeding.

Energy Efficiency

TNMP recovers the costs of its energy efficiency programs through an energy efficiency cost recovery factor. On August 28, 2012, the PUCT approved a settlement that permits TNMP to collect estimated 2013 program costs of $4.8 million, plus recovery of an aggregate of $0.4 million in under-collected costs from prior years, case expenses, and a performance bonus for 2011. TNMP's new rates were effective January 1, 2013. TNMP anticipates filing by June 1, 2013 to collect estimated 2014 energy efficiency program costs of $4.7 million and a $0.7 million bonus for 2012.

Transmission Cost of Service Rates

TNMP can update its transmission rates twice per year to reflect changes in its invested capital. Updated rates reflect the addition and retirement of transmission facilities, including appropriate depreciation, federal income tax and other associated taxes, and the approved rate of return on such facilities.

On August 23, 2012, TNMP filed an application to update its transmission rates to reflect changes in its invested capital. The application reflected an increase in total rate base of $26.4 million and requested an increase in revenues of $2.5 million annually. The PUCT approved the interim adjustment and TNMP implemented it on September 27, 2012.

On January 31, 2013, TNMP filed an application to further update its transmission rates to reflect changes in its invested capital. The requested increase in total rate base is $21.9 million, which will increase revenues $2.9 million annually. On March 19, 2013, the PUCT ALJ approved TNMP's interim transmission cost of service filing and rates went into effect with bills rendered March 20, 2013.

Fair Value of Derivative and Other Financial Instruments

Energy Related Derivative Contracts

Overview

The primary objective for the use of derivative instruments, including energy contracts, options, and futures, is to manage price risk associated with forecasted purchases of energy and fuel used to generate electricity, as well as managing anticipated generation capacity in excess of forecasted demand from existing customers. The Company's energy related derivative contracts manage commodity risk. PNM is required to meet the demand and energy needs of its retail and firm-requirements wholesale customers. PNM is exposed to market risk for its share of PVNGS Unit 3 and the needs of its firm-requirements wholesale customers not covered under a FPPAC. PNM’s operations are managed primarily through a net asset-backed strategy, whereby PNM’s aggregate net open forward contract position is covered by its forecasted excess generation capabilities or market purchases. PNM could be exposed to market risk if its generation capabilities were to be disrupted or if its load requirements were to be greater than anticipated, to the extent not covered by the FPPAC. If all or a portion of load requirements were required to be covered as a result of such unexpected situations, commitments would have to be met through market purchases. Additional information concerning the Company's energy related derivative contracts, including how commodity risk is managed, is contained in Note 8 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Commodity Risk

Marketing and procurement of energy often involve market risks associated with managing energy commodities and establishing open positions in the energy markets, primarily on a short-term basis. PNM routinely enters into various derivative instruments such as forward contracts, option agreements, and price basis swap agreements to economically hedge price and volume risk on power commitments and fuel requirements and to minimize the effect of market fluctuations in wholesale portfolios. PNM monitors the market risk of its commodity contracts using VaR calculations to maintain total exposure within management-prescribed limits in accordance with approved risk and credit policies.

Accounting for Derivatives

Under derivative accounting and related rules for energy contracts, the Company accounts for its various derivative instruments for the purchase and sale of energy based on the Company’s intent. Energy contracts that meet the definition of a derivative under GAAP and do not qualify, or are not designated, for the normal sales and purchases exception are recorded on the balance sheet at fair value at each period end. The changes in fair value are recognized in earnings unless specific hedge accounting criteria are met and elected. Normal sales and purchases are not marked to market and are reflected in results of operations when the underlying transactions settle.

During the three months ended March 31, 2013 and the year ended December 31, 2012, the Company was not hedging its exposure to the variability in future cash flows from commodity derivatives through designated cash flows hedges. The contracts recorded at fair value that do not qualify or are not designated for cash flow hedge accounting are classified as economic hedges. Economic hedges are defined as derivative instruments, including long-term power agreements, used to economically hedge generation assets, purchased power and fuel costs, and customer load requirements. Changes in the fair value of economic hedges are reflected in results of operations and are classified between operating revenues and cost of energy according to the intent of the hedge. The Company has no trading transactions.

Fair value is defined under GAAP as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value is based on current market quotes as available and is supplemented by modeling techniques and assumptions made by the Company to the extent quoted market prices or volatilities are not available. External pricing input availability varies based on commodity location, market liquidity, and term of the agreement. Valuations of derivative assets and liabilities take into account nonperformance risk including the effect of counterparties' and the Company’s credit risk. The Company regularly assesses the validity and availability of pricing data for its derivative transactions. Although the Company uses its best judgment in estimating the fair value of these instruments, there are inherent limitations in any estimation technique.

Commodity Derivatives

Commodity derivative instruments are summarized as follows:

	Economic Hedges
	March 31, 2013			December 31, 2012
PNMR and PNM	(In thousands)
Current assets	$	2,114		$	3,785
Deferred charges	—			352

	(5,917		)	(2,933		)
Net	$	(3,803	)	$	1,204

Certain of PNM's commodity derivative instruments included in the above table are subject to master netting agreements whereby assets and liabilities could be offset in the settlement process. The Company does not offset fair value, cash collateral, and accrued payable or receivable amounts recognized for derivative instruments under master netting arrangements and the above table reflects the gross amounts of assets and liabilities. The amounts that could be offset under master netting agreements were immaterial at March 31, 2013 and December 31, 2012.

At March 31, 2013 and December 31, 2012, PNMR and PNM had no amounts recognized for the legal right to reclaim cash collateral. In addition, at March 31, 2013 and December 31, 2012, amounts posted as cash collateral under margin arrangements were $1.9 million and $1.9 million for both PNMR and PNM. PNMR and PNM had no obligation to return cash collateral at March 31, 2013 and December 31, 2012. Cash collateral amounts are included in other current assets on the Condensed Consolidated Balance Sheets.

PNM has a NMPRC approved hedging plan to manage fuel and purchased power costs related to customers covered by its FPPAC. The table above includes less than $0.1 million of current assets and current liabilities at March 31, 2013 and December 31, 2012 related to this plan. The offsets to these amounts are recorded as regulatory assets and liabilities on the Condensed Consolidated Balance Sheets.

The following table presents the effect of commodity derivative instruments on earnings, excluding income tax effects. Commodity derivatives had no impact on OCI for the periods presented.

December 31, 2012
PNMR and PNM	1,127,500	(2,477,520	)

In connection with managing its commodity risks, the Company enters into master agreements with certain counterparties. If the Company is in a net liability position under an agreement, some agreements provide that the counterparties can request collateral from the Company if the Company’s credit rating is downgraded; other agreements provide that the counterparty may request collateral to provide it with “adequate assurance” that the Company will perform; and others have no provision for collateral.

The table below presents information about the Company’s contingent requirements to provide collateral under commodity contracts having an objectively determinable collateral provision that are in net liability positions and are not fully collateralized with cash. Contractual liability represents commodity derivative contracts recorded at fair value on the balance sheet, determined on an individual contract basis without offsetting amounts for individual contracts that are in an asset position and could be offset under master netting agreements with the same counterparty. The table only reflects cash collateral that has been posted under the existing contracts and does not reflect letters of credit under the Company’s revolving credit facilities that have been issued as collateral. Net exposure is the net contractual liability for all contracts, including those designated as normal purchases and sales, offset by existing cash collateral and by any offsets available under master netting agreements, including both asset and liability positions.

Sale of Power from PVNGS Unit 3

Since January 1, 2011, PNM has been selling power from its interest in PVNGS Unit 3 daily at market prices. PNM has established fixed rates for all of these sales through the end of 2013 through hedging arrangements that are accounted for as economic hedges. PNM is also partially hedged for 2014.

Non-Derivative Financial Instruments

The carrying amounts reflected on the Condensed Consolidated Balance Sheets approximate fair value for cash, receivables, and payables due to the short period of maturity. Available-for-sale securities are carried at fair value, which include unrealized gains on securities which have not been recognized in net earnings. Available-for-sale securities for PNMR and PNM consist of PNM assets held in the NDT for its share of decommissioning costs of PVNGS and a trust for PNM's share of post-term reclamation

costs related to the coal mines serving SJGS , which investments are included in "other investments" on the Condensed Consolidated Balance Sheet. PNMR and PNM do not have any unrecognized losses on available-for-sale securities. The fair value and gross unrealized gains of investments in available-for-sale securities are presented in the following table.

Held-to-maturity securities are those investments in debt securities that the Company has the ability and intent to hold until maturity. Held-to-maturity securities consist of the investment in PVNGS lessor notes and certain items within other investments.

The Company has no available-for-sale or held-to-maturity securities for which carrying value exceeds fair value. There are no impairments considered to be “other than temporary” that are included in AOCI and not recognized in earnings.

At March 31, 2013, the available-for-sale and held-to-maturity debt securities had the following final maturities:

Fair Value Disclosures

The Company determines the fair values of its derivative and other instruments based on the hierarchy established in GAAP, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. GAAP describes three levels of inputs that may be used to measure fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. Level 3 inputs used in determining fair values for the Company consist of internal valuation models.

For the NDT and reclamation trust investments, Level 2 fair values are provided by the trustee utilizing a pricing service. The pricing provider predominantly uses the market approach using bid side market value based upon a hierarchy of information for specific securities or securities with similar characteristics. For commodity derivatives, Level 2 fair values are determined based on market observable inputs, which are validated using multiple broker quotes, including forward price, volatility, and interest rate curves to establish expectations of future prices. Credit valuation adjustments are made for estimated credit losses based on the overall exposure to each counterparty. For long-term debt, Level 2 fair values are provided by an external pricing service. The pricing service primarily utilizes quoted prices for similar debt in active markets when determining fair value. For investments categorized as Level 3, primarily the PVNGS lessor notes and other investments, fair values were determined by discounted cash flow models that take into consideration discount rates that are observable for similar type assets and liabilities. Management of the Company independently verifies the information provided by pricing services.

The Company records any transfers between fair value hierarchy levels as of the end of each calendar quarter. There were no transfers between levels during the three months ended March 31, 2013 and 2012.

Items recorded at fair value on the Condensed Consolidated Balance Sheets are presented below:

Variable Interest Entities

Variable Interest Entities

Variable Interest Entities

GAAP determines how an enterprise evaluates and accounts for its involvement with variable interest entities, including determining the primary beneficiary of a variable interest entity, by focusing primarily on whether the enterprise has the power to direct the activities that most significantly impact the economic performance of a variable interest entity. GAAP also requires continual reassessment of the primary beneficiary of a variable interest entity. Additional information concerning PNM's variable interest entities is contained in Note 9 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Valencia

PNM has a PPA to purchase all of the electric capacity and energy from Valencia, a 145 MW natural gas-fired power plant near Belen, New Mexico, through May 2028. A third-party built, owns, and operates the facility while PNM is the sole purchaser of the electricity generated. PNM is obligated to pay fixed operations and maintenance and capacity charges in addition to variable operations and maintenance charges under this PPA. For the three months ended March 31, 2013 and 2012, PNM paid $4.7 million and $4.6 million for fixed charges and $0.1 million and $0.1 million for variable charges. PNM does not have any other financial obligations related to Valencia. The assets of Valencia can only be used to satisfy obligations of Valencia and creditors of Valencia do not have any recourse against PNM’s assets. PNM has concluded that the third party entity that owns Valencia is a variable interest entity and that PNM is the primary beneficiary of the entity under GAAP. As the primary beneficiary, PNM consolidates the entity in its financial statements. The assets and liabilities of Valencia set forth below are immaterial to PNM and, therefore, not shown separately on the Condensed Consolidated Balance Sheets. The owner's equity and net income of Valencia are considered attributable to non-controlling interest.

Summarized financial information for Valencia is as follows:

PVNGS Leases

PNM leases interests in Units 1 and 2 of PVNGS under arrangements, which were entered into in 1985 and 1986, that are accounted for as operating leases. PNM is not the legal or tax owner of the leased assets. PNM has an option to purchase the leased assets at appraised value at the end of the leases, but does not have a fixed price purchase option and does not provide residual value guarantees. As set forth in the leases, PNM has options to renew the leases at fixed rates, which represent 50% of the amounts during the original terms of the leases, for two years beyond the termination of the original lease terms. The option periods on all of the Unit 1 leases and one of the Unit 2 leases, amounting to 14% of the Unit 2 capacity under lease, may be further extended for up to an additional six years (the “Maximum Option Period”) if the appraised remaining useful lives and fair value of the leased assets are greater than parameters set forth in the leases. As discussed in Note 9 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K, PNM notified each of the lessors of the Unit 1 leases that it will extend each Unit 1 lease for the Maximum Option Period upon the expiration of the basic lease term on January 15, 2015. In addition, PNM notified each of the lessors in the Unit 2 leases that PNM will “retain” the assets leased under that lease upon the expiration of the basic lease term on January 15, 2016. PNM will be required to specify by notice to each of the lessors by January 15, 2014, whether on January 15, 2016 it will extend the Unit 2 leases or purchase the leased assets.

PNM is only obligated to make payments to the trusts for the scheduled semi-annual lease payments, which, net of amounts that will be returned to PNM through its ownership in related lessor notes, aggregate $65.9 million as of March 31, 2013 over the remaining original terms of the leases. Under certain circumstances (for example, final shutdown of the plant, the NRC issuing specified violation orders with respect to PVNGS, or the occurrence of specified nuclear events), PNM would be required to make specified payments to the beneficial owners and take title to the leased interests. If such an event had occurred as of March 31, 2013, PNM could have been required to pay the beneficial owners up to $160.4 million, which would result in PNM taking ownership of the leased assets and termination of the leases. PNM has no other financial obligations or commitments to the trusts or the beneficial owners. Creditors of the trusts have no recourse to PNM’s assets other than with respect to the contractual lease payments. PNM has no additional rights to the assets of the trusts other than the use of the leased assets.

PNM has evaluated the PVNGS lease arrangements, including the notices discussed above, and concluded that it does not have the power to direct the activities that most significantly impact the economic performance of the trusts and, therefore, is not the primary beneficiary of the trusts under GAAP. PNM has recorded no assets or liabilities related to the trusts other than the accrual of lease payments between the scheduled payment dates, which were $11.8 million at March 31, 2013 and $26.0 million at December 31, 2012 and are included in other current liabilities on the Condensed Consolidated Balance Sheets. For additional information regarding these leases, see Risk Factors, MD&A – Off Balance Sheet Arrangements and Note 7 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Delta

PNM has a PPA covering the entire output of Delta, which is a variable interest under GAAP. PNM makes fixed and variable payments to Delta under the PPA. PNM also controls the dispatch of the generating plant, which impacts the variable payments made under the PPA and impacts the economic performance of the entity that owns Delta. PNM makes fixed and variable payments to Delta under the PPA. For the three months ended March 31, 2013 and 2012, PNM incurred fixed capacity charges of $1.6 million and $1.5 million and variable energy charges of $0.2 million and $0.1 million under the PPA. PNM’s only quantifiable obligation under the PPA is to make the fixed payments, which as of March 31, 2013, aggregated $43.7 million through the end of the PPA in 2020. PNM will also pay variable costs, which cannot be quantified since the amounts are based on how much the generating plant is in operation.

This arrangement was entered into prior to December 31, 2003 and PNM was unsuccessful in obtaining the information necessary to determine if it is the primary beneficiary of the entity that owns Delta, or to consolidate that entity if it were determined that PNM is the primary beneficiary. Accordingly, PNM was unable to make those determinations and, as provided in GAAP, accounted for this PPA as an operating lease.

In December 2012, PNM entered into an agreement with the owners of Delta under which PNM would purchase the entity that owns Delta. At closing PNM would make a cash payment of $23.0 million, which would be adjusted for actual working capital compared to a targeted working capital and certain prepayments of debt. Delta had project financing debt of $18.5 million at March 31, 2013, including $3.0 million due by March 31, 2014, which PNM would retire at closing of the purchase. The purchase is subject to approval of the NMPRC and FERC, as well as other customary closing conditions. Furthermore, closing is subject to the seller remedying specified operational, NERC compliance, and environmental issues. FERC approved the purchase on February 26, 2013.

Delta informed PNM that at March 31, 2013, it had total assets of $26.1 million, including net property, plant, and equipment of $22.4 million, and total liabilities of $20.4 million. Delta also indicated its revenue for the three months ended March 31, 2013 was $1.8 million and its net earnings were $0.2 million. Consolidation of Delta would be immaterial to the Condensed Consolidated Balance Sheets of PNMR and PNM. Since all of Delta's revenues and expenses are attributable to its PPA arrangement with PNM, the primary impact of consolidating Delta to the Condensed Consolidated Statements of Earnings of PNMR and PNM would be to reclassify Delta's net earnings from operating expenses and reflect such amount as earnings attributable to a non-controlling interest, without any impact to net earnings attributable to PNMR and PNM.

Additional information concerning financing activities, including a TNMP cash-flow hedge that establishes a fixed interest rate on a variable rate loan, is contained in Note 6 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Short-term Debt

PNMR has a revolving credit financing capacity of $300.0 million under the PNMR Revolving Credit Facility. PNM has a revolving credit financing capacity of $400.0 million under the PNM Revolving Credit Facility. Both of these facilities currently expire on October 31, 2017 and provide for an additional one-year extension option, subject to approval by the lenders. PNMR borrowed $100.0 million under the PNMR Term Loan Agreement in December 2012. TNMP has a revolving credit facility with financing capacity of $75.0 million under the TNMP Revolving Credit Facility that expires in December 2015. At March 31, 2013, the weighted average interest rate was 1.96% for borrowings outstanding under the PNMR Revolving Credit Facility, 1.335% for the PNMR Term Loan Agreement, 1.71% for the PNM Revolving Credit Facility, and 1.83% for the TNMP Revolving Credit Facility. Short-term debt outstanding consisted of:

At May 1, 2013, PNMR, PNM, and TNMP had $228.4 million, $380.3 million, and $44.7 million of availability under their respective revolving credit facilities, including reductions of availability due to outstanding letters of credit. Total availability at May 1, 2013, on a consolidated basis, was $653.4 million for PNMR. As of May 1, 2013, TNMP had $28.5 million in borrowings from PNMR under their intercompany loan agreement. At May 1, 2013, PNMR, PNM and TNMP had consolidated invested cash of $4.5 million, none, and none.

Financing Activities

On March 6, 2013, TNMP commenced an offer to exchange any and all of TNMP's $265.5 million aggregate principal amount outstanding 9.50% First Mortgage Bonds, due 2019, Series 2009A, for a new series of 6.95% First Mortgage Bonds, due 2043, Series 2013A, and up to $140 in cash for each $1,000 of bonds exchanged. Settlement of the exchange offer occurred on April 3, 2013. Upon settlement, TNMP issued $93.2 million of 6.95% First Mortgage Bonds and paid an aggregate of $13.0 million in cash in exchange for $93.2 million of 9.50% First Mortgage Bonds, in addition to payment of accrued and unpaid interest on the exchanged bonds. The exchange will result in the recording of a $23.2 million premium on the 6.95% First Mortgage Bonds reflecting the contractual interest rate being in excess of the market rate of interest on the date of the exchange. A regulatory asset will be recorded to offset the premium, as well as the cash consideration paid in the exchange.

On April 22, 2013, PNM entered into a $75.0 million Term Loan Agreement (the “PNM Term Loan Agreement”) among PNM, the lenders identified therein, and Union Bank, N.A., as Administrative Agent. Funding of the PNM Term Loan Agreement occurred on April 22, 2013, at which time the funds were used to repay $75.0 million in borrowings made under the PNM Revolving Credit Facility. The PNM Term Loan Agreement bears interest at a variable rate and must be repaid on or before October 21, 2014. The PNM Term Loan Agreement includes customary covenants, including requirements to not exceed a maximum consolidated debt-to-consolidated capitalization ratio and customary events of default.

Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

Stock-Based Compensation

PNMR has various stock-based compensation programs, including stock options, restricted stock, and performance shares granted under the Performance Equity Plan (“PEP”). In 2011, the Company changed its approach to awarding stock-based compensation. As a result, no stock options have been granted in 2013 or 2012 and awards of restricted stock have increased. Certain restricted stock awards are subject to achieving performance or market targets and some also have time vesting requirements. Other awards of restricted stock are only subject to time vesting requirements. Additional information concerning stock-based compensation under PNMR's Performance Equity Plan ("PEP") is contained in Note 13 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K.

Restricted stock under the PEP refers to awards of stock subject to vesting, performance, or market conditions rather than to shares with contractual post-vesting restrictions. Generally, the awards vest ratably over three years from the grant date of the award. However, certain awards with performance or market conditions vest upon satisfaction of those conditions. In addition, plan provisions provide that upon retirement, participants become 100% vested in stock awards.

The stock-based compensation expense related to stock options and restricted stock awards without performance or market conditions is amortized to compensation expense over the requisite vesting period, which is generally three years. However, compensation expense for awards to participants that are retirement eligible on the award date is recognized immediately at the award date and is not amortized. Compensation expense for performance-based shares is recognized ratably over the performance period and is adjusted periodically to reflect the level of achievement expected to be attained. Compensation expense related to market-based shares is recognized ratably over the measurement period, regardless of the actual level of achievement, provided the employees remain with the Company during the period. At March 31, 2013 and December 31, 2012, PNMR had unrecognized expense related to stock awards of $6.8 million and $3.8 million. 

The Company uses the Black Scholes option pricing model to estimate the fair value of stock option awards based on multiple factors, including historical exercise patterns of employees in relatively homogeneous groups with respect to exercise and post-vesting employment termination behaviors, expected exercising patterns for these same homogeneous groups, and both the implied and historical volatility of PNMR's stock price. The grant date fair value for restricted stock and stock awards with Company internal performance targets is determined based on the market price of PNMR common stock on the date of the agreements reduced by the present value of future dividends, which will not be received prior to vesting, applied to the total number of shares that are anticipated to vest, although the number of shares that ultimately vest cannot be determined until after the performance periods end. The grant date fair value of stock awards with market targets is determined using Monte Carlo simulation models, which provide grant date fair values that include an expectation of the number of shares to vest.

The following table summarizes the weighted-average assumptions used to determine the awards grant date fair value:

	Three Months Ended March 31,
Restricted Shares and Performance Based Shares	2013			2012
Expected quarterly dividends per share	$	0.165		$	0.145
Risk-free interest rate	0.38		%	0.69		%
Market-Based Shares
Dividend yield	2.86		%	3.45		%
Expected volatility	25.11		%	43.98		%
Risk-free interest rate	0.36		%	1.04		%

The following table summarizes activity in stock options and restricted stock awards, including performance-based and market-based shares, for the three months endedMarch 31, 2013:

	Stock Option Shares		Weighted- Average Exercise Price		Restricted Stock		Weighted- Average Grant Date Fair Value
Outstanding at beginning of period	1,992,700		$	20.72	353,722		$	14.03

Outstanding at end of period	1,555,747		$	20.58	339,011		$	16.86

Included as granted and exercised in the tables above are 100,953 shares that were based upon achieving performance or market targets for 2012. The Board approved these shares in February 2013, including shares with market targets at near maximum levels.

PNMR also has share agreements that provide for performance or market targets through 2015. Excluded from the above tables are maximums of 188,129, 198,369, and 179,811 shares for periods ending in 2013, 2014, and 2015 that would be awarded if all performance or market criteria are achieved and all executives remain eligible.

In March 2012, the Company entered into a retention award agreement with its Chairman, President, and Chief Executive Officer under which she would receive 135,000 shares of PNMR's common stock if the Company meets specific market targets at the end of 2016 and she remains an employee of the Company. If the Company achieves specific market targets at the end of 2014 and she remains an employee of the Company, she would receive 35,000 of the total shares at that time. The retention award was made under the PEP and was approved by the Board on February 28, 2012. The above tables do not include any shares under the retention award agreement.

At March 31, 2013, the aggregate intrinsic values of stock options outstanding and exercisable were $7.8 million and $7.7 million with weighted-average remaining contract lives of 4.06 and 4.05 years. At March 31, 2013, the exercise price of 827,977 outstanding stock options is greater than the closing price of PNMR common stock on that date; therefore, those options have no intrinsic value.

The following table provides additional information concerning stock options and restricted stock activity, including performance-based and market-based shares:

Pension and Other Postretirement Benefit Plans

PNMR and its subsidiaries maintain qualified defined benefit pension plans, postretirement benefit plans providing medical and dental benefits, and executive retirement programs (“PNM Plans” and “TNMP Plans”). PNMR maintains the legal obligation for the benefits owed to participants under these plans.

Additional information concerning pension and OPEB plans is contained in Note 12 of the Notes to Consolidated Financial Statements in the 2012 Annual Reports on Form 10-K. Annual net periodic benefit cost (income) for the plans is actuarially determined using the methods and assumptions set forth in that note and is recognized ratably throughout the year.

PNM made contributions to its pension plan trust of $60.0 million and $77.7 million in the three months ended March 31, 2013 and 2012. PNM does not anticipate making additional contributions to its pension trust in 2013.  Based on current law, including recent amendments to funding requirements, and estimates of portfolio performance, PNM estimates minimum required contributions for its pension plan trust would total $49.1 million for 2014-2017. Minimum required contributions were developed using current funding assumptions, including discount rates of 4.8% to 5.2%. Actual amounts required to be funded in the future will depend on the actuarial assumptions at that time, including the appropriate discount rate. PNM may make additional contributions at its discretion. PNM made contributions to the OPEB trust of $0.5 million and $0.8 million in the three months ended March 31, 2013 and 2012. PNM expects contributions during 2013 to the OPEB trust to total $3.3 million.  Disbursements under the executive retirement program, which are funded by PNM and considered to be contributions to the plan, were $0.4 million in the three months ended March 31, 2013 and 2012 and are expected to total $1.5 million during 2013.

TNMP made contributions to its pension plan trust of $1.0 million and $5.3 million in the three months ended March 31, 2013 and 2012. TNMP does not anticipate making additional contributions to its pension trust in 2013. Based on current law, including recent amendments to funding requirements, and estimates of portfolio performance, TNMP estimates there would be no minimum required contributions to its pension plan trust for 2014-2017. Minimum required contributions were developed using current funding assumptions, including discount rates of 4.8% and 5.2%. Actual amounts to be funded in the future will depend on the actuarial assumptions at that time, including the appropriate discount rate. TNMP may make additional contributions at its discretion. TNMP made contributions to the OPEB trust of zero and $0.3 million in the three months ended March 31, 2013 and 2012. TNMP expects contributions during 2013 to the OPEB trust to total $0.3 million. Disbursements under the executive retirement program, which are funded by TNMP and considered to be contributions to the plan, were less than $0.1 million in the three months ended March 31, 2013 and 2012 and are expected to total $0.1 million during 2013.

Income Taxes (Notes)

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

As required under GAAP, the Company makes an estimate of its anticipated effective tax rate for the year as of the end of each quarterly period within its fiscal year. Year-to-date income tax expense is then calculated by applying the anticipated annual effective tax rate to year-to-date earnings before taxes, which includes the earnings attributable to the Valencia non-controlling interest. GAAP also provides that certain unusual or infrequently occurring items, as well as adjustments due to enactment of new tax laws, be excluded from the estimated annual effective tax rate calculation.

On January 3, 2013, the American Taxpayer Relief Act of 2012, which extended fifty percent bonus depreciation, was signed into law.  Due to provisions in the act, taxes payable to the State of New Mexico for 2013 were reduced, which results in an impairment of New Mexico wind energy production tax credits. In accordance with GAAP, PNMR was required to record this impairment, which after federal income tax benefit amounted to $1.5 million, as additional income tax expense during the three months ended March 31, 2013. This impairment is reflected in PNMR's Corporate and Other segment.

On April 30,2013, the IRS issued Revenue Procedure 2013-24, which provides a safe harbor method of accounting that taxpayers may use to determine repair costs for electric generation property.  Adoption of the safe harbor method is elective for years ending on or after December 31, 2012.  The Company is evaluating the possible effects of adopting the safe harbor method and the ultimate outcome cannot be determined at this time.
