Derivative Instruments

10: DERIVATIVE INSTRUMENTS

In order to limit exposure to certain market risks, primarily changes in commodity prices, interest rates, and foreign exchange rates, CMS Energy and Consumers may enter into various risk management contracts, such as forward contracts, futures, options, and swaps. The contracts used to manage market risks may qualify as derivative instruments. Neither CMS Energy nor Consumers enters into any derivatives for trading purposes.

Commodity Price Risk: In order to support ongoing operations, CMS Energy and Consumers enter into contracts for the future purchase and sale of various commodities, such as electricity, natural gas, and coal. These forward contracts are generally long-term in nature and result in physical delivery of the commodity at a contracted price. Most of these contracts are not subject to derivative accounting because:

• they do not have a notional amount (that is, a number of units specified in a derivative instrument, such as MWh of electricity or bcf of natural gas);

• they qualify for the normal purchases and sales exception; or

• there is not an active market for the commodity.

Consumers' coal purchase contracts are not derivatives because there is not an active market for the coal it purchases. If an active market for coal develops in the future, some of these contracts may qualify as derivatives. Since Consumers is subject to regulatory accounting, the resulting fair value gains and losses would be deferred as regulatory assets or liabilities and would not affect net income.

Consumers also uses FTRs to manage price risk related to electricity transmission congestion. An FTR is a financial instrument that entitles its holder to receive compensation or requires its holder to remit payment for congestion-related transmission charges. FTRs are accounted for as derivatives. Under regulatory accounting, all changes in fair value associated with these instruments are deferred as regulatory assets or liabilities until the instruments are settled.

CMS ERM has not designated its contracts to purchase and sell electricity and natural gas as normal purchases and sales and, therefore, CMS Energy accounts for those contracts as derivatives.

The fair value of CMS Energy's commodity contracts not designated as hedging instruments and recorded in other assets were $3 million at December 31, 2011 and $1 million at December 31, 2010. The fair value of Consumers' commodity contracts not designated as hedging instruments and recorded in other assets were $2 million at December 31, 2011 and $1 million at December 31, 2010. The fair value of CMS Energy's commodity contracts not designated as hedging instruments and recorded in other liabilities were $7 million at December 31, 2011 and $4 million at December 31, 2010. Consumers did not have any contracts recorded as liabilities at December 31, 2011 and 2010.

Presented in the following table is the effect on CMS Energy's and Consumers' consolidated statements of income of their derivatives not designated as hedging instruments:
