The accompanying notes are an integral part of these statements. Basis of PresentationCMS Energy’s condensed financial statements have been prepared on a parent-only basis. In accordance with Rule 12-04 of Regulation S-X, these parent-only financial statements do not include all of the information and notes required by GAAP for annual financial statements, and therefore these parent-only financial statements and other information included should be read in conjunction with CMS Energy’s audited consolidated financial statements contained within Item 8. Financial Statements and Supplementary Data.Contingencies Gas Index Price Reporting Litigation: CMS Energy, along with CMS MST, CMS Field Services, Cantera Natural Gas, Inc., and Cantera Gas Company, were named as defendants in four class action lawsuits filed in Kansas, Missouri, and Wisconsin and one individual lawsuit filed in Kansas; these lawsuits arose as a result of alleged inaccurate natural gas price reporting to publications that report trade information. Allegations included price-fixing conspiracies, restraint of trade, and artificial inflation of natural gas retail prices. In 2016, CMS Energy entities reached a settlement with the plaintiffs in the Kansas and Missouri class action cases for an amount that was not material to CMS Energy. In 2017, the federal district court approved the settlement. In 2019, CMS Energy and the plaintiffs in the remaining Kansas individual lawsuit and the Wisconsin class action lawsuit engaged in settlement discussions and CMS Energy recorded a $30 million liability at December 31, 2019 as the probable estimate to settle the two cases. The parties executed a settlement agreement in the Kansas case in February 2020, and that case is now complete. In the Wisconsin case, a settlement agreement was approved in August 2020 and that case is now complete. Guarantees CMS Energy has issued guarantees with a maximum potential obligation of $596 million on behalf of some of its wholly owned subsidiaries and related parties. CMS Energy’s maximum potential obligation consists primarily of potential payments: •to third parties under certain commodity purchase and swap agreements entered into with CMS ERM •to third parties under certain agreements entered into with Grand River Wind, LLC, a wholly owned subsidiary of CMS Enterprises •to EGLE on behalf of CMS Land and CMS Capital, for environmental remediation obligations at Bay Harbor •to the U.S. Department of Energy on behalf of Consumers, in connection with Consumers’ 2011 settlement agreement with the U.S. Department of Energy regarding damages resulting from the department’s failure to accept spent nuclear fuel from nuclear power plants formerly owned by Consumers •to a tax equity investor under certain agreements in connection with the purchase of a VIE The expiry dates of these guarantees vary, depending upon contractual provisions or upon the statute of limitations under the relevant governing law. Note Payable—IntercompanyIn 2018, CMS Energy issued a demand note payable to the DB SERP rabbi trust, of which $124 million was attributable to CMS Energy’s subsidiaries. The demand note bears interest at an annual rate of 4.10 percent and has a maturity date of 2028. This note payable is not recorded at fair value; however, its carrying value approximates fair value at December 31, 2020. This fair value measurement is classified in Level 3 within the fair value hierarchy.
