Item 1.01 Entry into a Material Definitive Agreement

Item 1.02 Termination of a Material Definitive Agreement

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant

On July 27, 2012, Public Service Company of Colorado (“PSCo”) entered into an amended and restated credit agreement with JPMorgan Chase Bank, N.A., as Administrative Agent, Bank of America, N.A., and Barclays Bank Plc, as Syndication Agents, and Wells Fargo Bank, National Association, as Documentation Agent, and the several lenders party thereto.  PSCo’s new $700 million credit facility (“New Facility”) amends and restates its prior $700 million facility scheduled to expire in March 2015.

The New Facility is unsecured, has a five-year term, contains maturity extension provisions (for two additional one-year periods) and, under certain circumstances, may be increased by up to $100 million.  The New Facility permits borrowings at interest rates equal to the Eurodollar rate, plus a margin of 87.5 basis points to 175 basis points, or an alternate base rate.  The New Facility also provides for a commitment fee that ranges from 7.5 basis points to 27.5 basis points on the unused portion of the line.  Interest rates and commitment fees are based on PSCo’s then-current senior unsecured credit ratings.  Advances under the New Facility are subject to certain conditions precedent, including the accuracy of certain representations and warranties and the absence of any default or event of default.  Advances under the New Facility will be used for general corporate purposes, including the repayment of outstanding indebtedness from time to time and as back-up liquidity for letters of credit.

The New Facility has one financial covenant, requiring that PSCo’s debt to total capitalization ratio be less than or equal to 65 percent.  The New Facility also contains covenants that restrict PSCo and certain of its subsidiaries in respect of, among other things, mergers and consolidations, sales of all or substantially all assets, incurrence of liens and transactions with affiliates. The New Facility is subject to acceleration upon the occurrence of an event of default, including cross-default to indebtedness in excess of $75 million in the aggregate, change of control (as defined in the New Facility), nonpayment of monetary judgments of $75 million or more, and the occurrence of certain Employee Retirement Income Security Act of 1974 and bankruptcy events.

A copy of the New Facility is filed as Exhibit 99.01 hereto and is incorporated by reference herein.  The description of the New Facility above is qualified in its entirety by reference to the full text of the New Facility.
