ASSET RETIREMENT OBLIGATIONS

A reconciliation of the ARO for the nine months ended September 30, 2015 follows:



	DTE Energy		DTE Electric
	(In millions)
Asset retirement obligations at December 31, 2014	$	1,962	$	1,796
Accretion	90		83
Revision in estimated cash flows	128		128
Asset retirement obligations at September 30, 2015	$	2,180	$	2,007

The Revision in estimated cash flows was principally attributed to the impact of the Coal Combustion Residual Rule on DTE Electric's coal ash storage facility AROs. Refer to Note 12 to the Consolidated Financial Statements, "Commitments and Contingencies", for discussion of the implications of the Coal Combustion Residual Rule.
