16. Regulatory Assets and Liabilities
Xcel Energy’s regulated businesses prepare their consolidated financial statements in accordance with the provisions of the
applicable accounting guidance, as discussed in Note 1 to the consolidated financial statements. Under this guidance, regulatory
assets and liabilities can be created for amounts that regulators may allow to be collected, or may require to be paid back to
customers in future electric and natural gas rates. Any portion of Xcel Energy’s business that is not regulated cannot establish
regulatory assets and liabilities. If changes in the utility industry or the business of Xcel Energy no longer allow for the
application of regulatory accounting guidance under GAAP, Xcel Energy would be required to recognize the write-off of
regulatory assets and liabilities in its consolidated statement of income.
