1 In conjunction with the purchase of its interest in Aviator Wind Equity Holdings, CMS Enterprises assumed certain indemnity obligations that protect the associated tax equity investor against losses incurred as a result of breaches of representations and warranties provided by Aviator Wind Equity Holdings and its subsidiaries. These obligations are generally capped at an amount equal to the tax equity investor’s capital contributions plus a specified return, less any distributions and tax benefits it receives, in connection with its membership interest in Aviator Wind. CMS Enterprises would recover 49 percent of any amounts paid to the tax equity investor from the other owner of Aviator Wind Equity Holdings. Additionally, Aviator Wind holds insurance coverage that would partially protect against losses incurred as a result of certain failures to qualify for production tax credits. For further details on CMS Enterprises’ ownership interest in Aviator Wind Equity Holdings, see Note 12, Variable Interest Entities. 2 These obligations arose from stock and asset sale agreements under which CMS Energy or a subsidiary of CMS Energy indemnified the purchaser for losses resulting from various matters, primarily claims related to taxes. The maximum obligation amount is mostly related to the Equatorial Guinea tax claim discussed in the CMS Energy Contingencies section of this Note. CMS Energy believes the likelihood of material loss to be remote for the indemnity obligations not recorded as liabilities. 3 This obligation comprises a guarantee provided by Consumers to the U.S. Department of Energy in connection with a settlement agreement regarding damages resulting from the department’s failure to accept spent nuclear fuel from nuclear power plants formerly owned by Consumers.
