¹  Includes current portion of notes receivable of $26 million at June 30, 2012 and $19 million at December 31, 2011.

²  Includes current portion of long-term debt of $631 million at June 30, 2012 and $1,033 million at December 31, 2011.

³  Includes current portion of long-term debt of $40 million at June 30, 2012 and $339 million at December 31, 2011.

Notes receivable consist of EnerBank's fixed-rate installment loans. EnerBank estimates the fair value of these loans using a discounted cash flows technique that incorporates market interest rates as well as assumptions about the remaining life of the loans and credit risk.

CMS Energy and Consumers estimate the fair value of their long-term debt using quoted prices from market trades of the debt, if available. In the absence of quoted prices, CMS Energy and Consumers calculate market yields and prices for the debt using a matrix method that incorporates market data for similarly rated debt. Depending on the information available, other valuation techniques may be used that rely on internal assumptions and models. CMS Energy includes the value of the conversion features in estimating the fair value of its convertible debt, and incorporates, as appropriate, information on the market prices of CMS Energy common stock.

The effects of third-party credit enhancements are excluded from the fair value measurements of long-term debt. At June 30, 2012 and December 31, 2011, CMS Energy's long-term debt included $103 million principal amount that was supported by third-party credit enhancements. This entire principal amount was at Consumers.
