Debt Disclosure [Abstract] |
Financing | Financing The Company’s financing strategy includes both short-term and long-term borrowings. The Company utilizes short-term revolving credit facilities, as well as cash flows from operations, to provide funds for both construction and operating expenditures. Depending on market and other conditions, the Company will periodically sell long-term debt or enter into term loan arrangements and use the proceeds to reduce borrowings under the revolving credit facilities or refinance other debt. Prior to July 2018, each of the Company’s revolving credit facilities and term loans contained a single financial covenant, which required the maintenance of a debt-to-capitalization ratio of less than or equal to 65%. In July 2018, the PNMR Revolving Credit Facility, the PNMR Development Revolving credit facility, and PNMR’s term loans were each amended such that PNMR is now required to maintain a debt-to-capitalization ratio of less than or equal to 70%. The debt-to-capitalization ratio requirement remains at less than or equal to 65% for the PNM and TNMP agreements. The Company’s revolving credit facilities and term loans generally also contain customary covenants, events of default-cross default provisions, and change-of-control provisions. PNM must obtain NMPRC approval for any financing transaction having a maturity of more than 18 months. In addition, PNM files its annual short-term financing plan with the NMPRC. Financing Activities PNMR At January 1, 2016, PNMR had outstanding the $150.0 million PNMR Term Loan, which matured and was repaid on December 21, 2016. At January 1, 2016, PNMR had outstanding the $150.0 million PNMR 2015 Term Loan, which matured and was repaid on March 9, 2018. As discussed in Note 16, NM Capital, a wholly-owned subsidiary of PNMR, entered into a $125.0 million term loan agreement (the “BTMU Term Loan”) with BTMU, as lender and administrative agent, as of February 1, 2016. The BTMU Term Loan had a maturity date of February 1, 2021 and bore interest at a rate based on LIBOR plus a customary spread. PNMR, as parent company of NM Capital, guaranteed NM Capital’s obligations to BTMU. NM Capital utilized the proceeds of the BTMU Term Loan to provide funding of $125.0 million (the “Westmoreland Loan”) to a ring-fenced, bankruptcy-remote, special-purpose entity subsidiary of Westmoreland to finance Westmoreland’s purchase of SJCC. The BTMU Term Loan agreement required that NM Capital utilize all amounts, less taxes and fees, it received under the Westmoreland Loan to repay the BTMU Term Loan. On May 22, 2018, the full principal balance outstanding under the Westmoreland Loan of $50.1 million was repaid. NM Capital used a portion of the proceeds to repay all remaining principal of $43.0 million owed under the BTMU Term Loan. These payments effectively terminated the loan agreements. In addition, PNMR’s guarantee of NM Capital’s obligations was also effectively terminated. See Note 10. On October 21, 2016, PNMR entered into letter of credit arrangements with JPMorgan Chase Bank, N.A. (the “JPM LOC Facility”) under which letters of credit aggregating $30.3 million were issued to facilitate the posting of reclamation bonds, which SJCC is required to post in connection with permits relating to the operation of the San Juan mine (Note 16). On December 21, 2016, PNMR entered into two term loan agreements: (1) a $100.0 million term loan agreement (the “PNMR 2016 One-Year Term Loan”) among PNMR, the lenders identified therein, and Wells Fargo Bank, National Association, as administrative agent, that was to mature on December 21, 2017; and (2) a $100.0 million term loan agreement (the “PNMR 2016 Two-Year Term Loan”) among PNMR and JPMorgan Chase Bank, N.A., as lender and administrative agent, that matured on December 21, 2018. The proceeds of these term loans were used to repay the $150.0 million PNMR Term Loan and to reduce borrowings under the PNMR Revolving Credit Facility. On December 15, 2017, the PNMR 2016 One-Year Term Loan was extended to December 14, 2018. On March 9, 2018, PNMR issued $300.0 million aggregate principal amount of 3.250% SUNs (the “PNMR 2018 SUNs”), which mature on March 9, 2021. The proceeds from the offering were used to repay the $150.0 million PNMR 2015 Term Loan that was due on March 9, 2018 and to reduce borrowings under the PNMR Revolving Credit Facility. On November 26, 2018, PNMR Development entered into a $90.0 million term loan agreement (the “PNMR Development Term Loan”), among PNMR Development and KeyBank, N.A., as administrative agent and sole lender. Proceeds from the PNMR Development Term Loan were used to repay short-term borrowings under the PNMR Development’s revolving credit facility and to repay borrowings under its intercompany loan from PNMR. The PNMR Development Term Loan bears interest at a variable rate, which was 3.32% on December 31, 2018, and matures on November 26, 2020. PNMR, as parent company of PNMR Development, has guaranteed PNMR Development’s obligations under the loan. The PNMR Development Term Loan requires PNMR to maintain a debt-to-capitalization ratio of less than or equal to 70%, and contains customary events of default, a cross-default provision, and a change-of-control provision. On December 14, 2018, PNMR entered into a $150.0 million term loan agreement (the “PNMR 2018 One-Year Term Loan”) among PNMR, the lenders identified therein, and MUFG Bank, Ltd., as administrative agent. The proceeds from the PNMR 2018 One-Year Term Loan were used to repay the PNMR 2016 One-Year Term Loan (as extended), a portion of the PNMR 2016 Two-Year Term Loan, and for general corporate purposes. The PNMR 2018 One-Year Term Loan bears interest at a variable rate, which was 3.20% at December 31, 2018, and matures on December 13, 2019. On December 21, 2018, PNMR entered into a $50.0 million term loan agreement (the “PNMR 2018 Two-Year Term Loan”), between PNMR and Bank of America, N.A. as sole lender. Proceeds from the PNMR 2018 Two-Year Term Loan were used to repay the remaining amount owed under the PNMR 2016 Two-Year Term Loan and for general corporate purposes. The PNMR 2018 Two-Year Term Loan bears interest at a variable rate, which was 3.28% at December 31, 2018, and matures on December 21, 2020. PNMR has an automatic shelf registration that provides for the issuance of various types of debt and equity securities that expires in March 2021. PNM At January 1, 2016, PNM had a $125.0 million multi-draw term loan facility (the “PNM Multi-draw Term Loan”) that had a maturity date of June 21, 2016. The PNM Multi-draw Term Loan was repaid on May 20, 2016. On May 20, 2016, PNM entered into a $175.0 million term loan agreement (the “PNM 2016 Term Loan”) between PNM and JPMorgan Chase Bank, N.A., as lender and administrative agent. The PNM 2016 Term Loan bore interest at a variable rate and had a maturity date of November 17, 2017. PNM used a portion of the proceeds of the PNM 2016 Term Loan to prepay without penalty the $125.0 million outstanding under the PNM Multi-draw Term Loan. The PNM 2016 Term Loan was repaid on July 20, 2017. On September 27, 2016, PNM participated in the issuance and sale of an aggregate of $146.0 million of PCRBs by the City of Farmington, New Mexico. The proceeds from the sale were utilized to refund an aggregate of $146.0 million of outstanding PCRBs previously issued by the City of Farmington. The arrangements governing the PCRBs result in PNM reflecting the bonds as debt on its financial statements. The PCRBs bear interest at a rate of 1.875% for the period from September 27, 2016 through September 30, 2021, have a mandatory tender for remarketing on October 1, 2021, and a final maturity on April 1, 2033. At January 1, 2016, PNM had $37.0 million of outstanding PCRBs, which have a final maturity of June 1, 2040, and $20.0 million of outstanding PCRBs which have a final maturity of June 1, 2042. These PCRBs were subject to mandatory tender for remarketing on June 1, 2017 and were successfully remarketed on that date. The $37.0 million of PCRBs now bear interest at 2.125% and the $20.0 million of PCRBs now bear interest at 2.45%. Both series are now subject to mandatory tender for remarketing on June 1, 2022. On July 20, 2017, PNM entered into a $200.0 million term loan agreement (the “PNM 2017 Term Loan”) between PNM and JPMorgan Chase Bank, N.A., as lender and administrative agent, and U.S. Bank National Association, as lender. The PNM 2017 Term Loan bore interest at a variable rate, which was 3.26% at December 31, 2018, and was repaid on January 18, 2019. PNM used the proceeds of the PNM 2017 Term Loan to prepay without penalty the $175.0 million PNM 2016 Term Loan and to reduce short-term borrowings. On July 28, 2017, PNM entered into an agreement (the “PNM 2017 Senior Unsecured Note Agreement”) with institutional investors for the sale of $450.0 million aggregate principal amount of eight series of Senior Unsecured Notes (the “PNM 2018 SUNs”) offered in private placement transactions. On May 14, 2018 PNM issued $350.0 million of the PNM 2018 SUNs under that agreement (at fixed annual interest rates ranging from 3.15% to 4.50% for terms between 5 and 30 years) and used the proceeds to repay an equal amount of PNM’s 7.95% SUNs that matured on May 15, 2018. On July 31, 2018, PNM issued the remaining $100.0 million of the PNM 2018 SUNs (at fixed annual interest rates of 3.78% and 4.60% for terms of 10 and 30 years) and used the proceeds to repay an equal amount of PNM’s 7.50% SUNs on August 1, 2018. The PNM 2017 Senior Unsecured Note Agreement includes customary covenants, including a covenant that requires the maintenance of a debt-to-capitalization ratio of less than or equal to 65%, customary events of default, including a cross-default provision, and covenants regarding parity of financial covenants, liens and guarantees with respect to PNM’s material credit facilities. In the event of a change of control, PNM will be required to offer to prepay the PNM 2018 SUNs at par. PNM will have the right to redeem any or all of the PNM 2018 SUNs prior to their respective maturities, subject to payment of a customary make-whole premium. On April 9, 2018, PNMR Development deposited $68.2 million with PNM related to potential transmission network interconnections, which is shown as a cash inflow from financing activities on PNM’s Consolidated Statements of Cash Flows. PNM used the deposit to repay intercompany borrowings. PNM is required to pay interest to PNMR Development to the extent work under the interconnections has not been performed. During the year ended December 31, 2018, PNM recognized $2.4 million of interest expense under the agreement. At December 31, 2018, PNM’s remaining obligation under the interconnection agreement with PNMR Development of $68.2 million, excluding unpaid interest, is reflected in other deferred credits on PNM’s Consolidated Balance Sheets. As required by GAAP, all intercompany transactions related to this deposit have been eliminated on PNMR’s Consolidated Financial Statements. On January 18, 2019, PNM entered into a $250.0 million term loan agreement (the “PNM 2019 Term Loan”) among PNM, the lenders identified therein, and U.S. Bank N.A., as administrative agent. PNM used the proceeds of the PNM 2019 Term Loan to repay the PNM 2017 Term Loan, short-term borrowings under the PNM Revolving Credit Facility, and for general corporate purposes. The PNM 2019 Term Loan bears interest at a variable rate, which was 3.13% at February 22, 2019, and must be repaid on or before July 17, 2020.

Interest Rate Hedging Activities In September 2015, PNMR entered into a hedging agreement whereby it effectively established a fixed interest rate of 1.927% for borrowings under the PNMR 2015 Term Loan for the period from January 11, 2016 through its maturity on March 9, 2018. In 2017, PNMR entered into three separate four-year hedging agreements whereby it effectively established fixed interest rates of 1.926%, 1.823%, and 1.629%, plus customary spreads over LIBOR, subject to change if there is a change in PNMR’s credit rating, for three separate tranches, each of $50.0 million, of its variable rate debt. These hedge agreements are accounted for as cash flow hedges. These hedge agreements had fair value gains totaling $1.0 million at December 31, 2018 that is included in other deferred charges and $1.4 million at December 31, 2017 that is included in other current assets on the Consolidated Balance Sheets. The fair values were determined using Level 2 inputs under GAAP, including using forward LIBOR curves under the mid-market convention to discount cash flows over the remaining term of the agreement. Borrowing Arrangements Between PNMR and its Subsidiaries PNMR has one-year intercompany loan agreements with its subsidiaries. Individual subsidiary loan agreements vary in amount up to $100.0 million and have either reciprocal or non-reciprocal terms. Interest charged to the subsidiaries is equivalent to interest paid by PNMR on its short-term borrowings or the money-market interest rate if PNMR does not have any short-term borrowings outstanding. TNMP had outstanding borrowings of $0.1 million from PNMR at December 31, 2018 and zero at February 22, 2019. TNMP had no borrowings at December 31, 2017. PNM had outstanding borrowings of $19.8 million from PNMR at December 31, 2018 and zero at February 22, 2019. PNM had no outstanding borrowings at December 31, 2017. Short-term Debt Currently, the PNMR Revolving Credit Facility has a financing capacity of $300.0 million and the PNM Revolving Credit Facility has a financing capacity of $400.0 million. Both facilities currently expire on October 31, 2023 and contain options to be extended through October 2024. However, one lender, whose current commitment is $10.0 million under the PNMR Revolving Credit Facility and $40.0 million under the PNM Revolving Credit Facility, did not agree to extend its commitments beyond October 31, 2020. Unless one or more of the other current lenders or a new lender assumes the commitments of the non-extending lender, the financing capacities will be reduced to $290.0 million for the PNMR Revolving Credit Facility and $360.0 million for the PNM Revolving Credit Facility beginning on November 1, 2020. The TNMP Revolving Credit Facility is a $75.0 million revolving credit facility secured by $75.0 million aggregate principal amount of TNMP first mortgage bonds. In September 2017, the TNMP Revolving Credit Facility was extended to mature on September 23, 2022. At January 1, 2016, PNM had a $50.0 million unsecured revolving credit facility (the “PNM 2014 New Mexico Credit Facility”) that was scheduled to expire on January 8, 2018. On December 12, 2017, PNM entered into a new $40.0 million unsecured revolving credit facility (the “PNM 2017 New Mexico Credit Facility”) by and among PNM, the lenders identified therein, U.S. Bank National Association, as Administrative Agent, and BOKF, NA dba Bank of Albuquerque, as Syndication Agent to replace the PNM 2014 New Mexico Credit Facility. The eight participating lenders are all banks that have a significant presence or are headquartered in New Mexico. The PNM 2017 New Mexico Credit Facility expires on December 12, 2022 and contains covenants and conditions similar to those in the PNM Revolving Credit Facility. On February 26, 2018, PNMR Development entered into a revolving credit facility with Wells Fargo Bank, National Association, as lender, which allows PNMR Development to borrow up to $24.5 million on a revolving credit basis and also provides for the issuance of letters of credit. The facility was scheduled to expire on February 25, 2019. On February 22, 2019, PNMR Development amended the revolving credit facility to increase the capacity to $25.0 million and to expire on February 24, 2020. The PNMR Development Revolving Credit Facility bears interest at a variable rate and contains terms similar to the PNMR Revolving Credit Facility. PNMR has guaranteed the obligations of PNMR Development under the facility. PNMR Development uses the facility to finance its participation in NMRD and for other activities.
