PNM will use the gross proceeds from the PNM 2021 SUNs for funding of capital expenditures, including funding for the purchase of the Western Spirit transmission line, refinancing existing short-term debt, and general corporate purposes. The terms of the PNM Note Purchase Agreement, which will continue to apply so long as any of the PNM 2021 SUNs are outstanding, include customary covenants, including a covenant that requires PNM to maintain 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 PNMs material credit facilities. In the event of a change of control (as defined in the PNM Note Purchase Agreement, which definition would not include the pending merger between PNM Resources, Inc. and Avangrid, Inc.), PNM will be required to offer to prepay the PNM 2021 SUNs at par. PNM has the right to redeem any or all of the PNM 2021 SUNs prior to their maturities, subject to payment of a customary make-whole premium.
