IMPLEMENTATION OF NEW ACCOUNTING STANDARDS

ASU 2011-05, Presentation of Comprehensive Income: This standard, which became effective January 1, 2012 for CMS Energy and Consumers, eliminates the option of reporting other comprehensive income and its components on the statement of changes in equity. Prior to the implementation of this standard, both CMS Energy and Consumers used this option for their consolidated financial statements. Under the standard, entities are required to present either a single continuous statement of comprehensive income, containing both net income and components of other comprehensive income, or two separate consecutive statements. CMS Energy and Consumers have chosen to present two separate consecutive statements. This standard affects only the presentation of comprehensive income on CMS Energy's and Consumers' consolidated financial statements.

ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs: This standard, which became effective January 1, 2012 for CMS Energy and Consumers, is the result of a joint project of the Financial Accounting Standards Board and the International Accounting Standards Board. The primary objective of the standard is to ensure that fair value has the same meaning under GAAP and International Financial Reporting Standards and to establish common fair value measurement guidance in the two sets of standards. The standard does not change the overall fair value model in GAAP, but it amends various fair value principles and establishes additional disclosure requirements. This standard did not impact CMS Energy's or Consumers' consolidated income, cash flows, or financial position, but did require additional disclosures.
