CMS Energy

The segments reported for CMS Energy are:

•electric utility, consisting of regulated activities associated with the generation, purchase, distribution, and sale of electricity in Michigan

•gas utility, consisting of regulated activities associated with the purchase, transmission, storage, distribution, and sale of natural gas in Michigan

•enterprises, consisting of various subsidiaries engaging in domestic independent power production, including the development and operation of renewable generation, and the marketing of independent power production

•EnerBank, a Utah state-chartered, FDIC-insured industrial bank providing primarily unsecured, fixed-rate installment loans throughout the U.S. to finance home improvements

Beginning in 2021, CMS Land, which holds the environmental remediation obligations at Bay Harbor, will be included within other reconciling items rather than within the enterprises segment. This change was not material and was made to align segment reporting with the legal organization and internal reporting of CMS Energy.
