Notes to the Condensed Financial Statements

1: Basis of Presentation

CMS 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.

2: Guarantees

CMS Energy has issued guarantees with a maximum potential obligation of $886 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 sales agreements entered into by CMS ERM and other subsidiaries of NorthStar Clean Energy

  • to tax equity investors that hold membership interests in certain VIEs held by NorthStar Clean Energy

  • 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

The expiration dates of these guarantees vary, depending upon contractual provisions or upon the statute of limitations under the relevant governing law.
