SIGNIFICANT ACCOUNTING POLICIES

Other Income

Other income for the Registrants is recognized for non-operating income such as equity earnings, allowance for equity funds used during construction and contract services. DTE Energy's Power & Industrial Projects segment also recognizes Other income in connection with the sale of membership interests in reduced emissions fuel facilities to investors. In exchange for the cash received, the investors will receive a portion of the economic attributes of the facilities, including income tax attributes. The transactions are not treated as a sale of membership interests for financial reporting purposes. Other income is considered earned when refined coal is produced and tax credits are generated. Power & Industrial Projects recognized approximately $19 million and $17 million of Other income for the three months ended March 31, 2015 and 2014, respectively.

Changes in Accumulated Other Comprehensive Income (Loss)

For the three months ended March 31, 2015 and 2014, reclassifications out of accumulated other comprehensive income (loss) for the Registrants were not material. Refer to Note 13 to the Consolidated Financial Statements, "Retirement Benefits and Trusteed Assets", regarding the transfer of a portion of DTE Electric benefit obligations during the year. Changes in accumulated other comprehensive income (loss) are presented in the Registrants' Consolidated Statements of Changes in Equity.

Intangible Assets

DTE Energy has certain intangible assets relating to emission allowances, renewable energy credits and non-utility contracts as shown below:



	March 31,		December 31,
	2015		2014
	(In millions)
Emission allowances	$	1	$	1
Renewable energy credits	46		45
Contract intangible assets	123		122
	170		168
Less accumulated amortization	60		57
Intangible assets, net	110		111
Less current intangible assets	10		9
	$	100	$	102

DTE Electric has certain intangible assets relating to emission allowances and renewable energy credits as shown below:



	March 31,		December 31,
	2015		2014
	(In millions)
Emission allowances	$	1	$	1
Renewable energy credits	46		45
	47		46
Less current intangible assets	10		9
	$	37	$	37

Emission allowances and renewable energy credits are charged to expense, using average cost, as the allowances and credits are consumed in the operation of the business by the Registrants. DTE Energy amortizes contract intangible assets on a straight-line basis over the expected period of benefit, ranging from 1 to 26 years.

Income Taxes

The effective tax rate and unrecognized tax benefits of the Registrants are as follows:



	Effective Tax Rate				Unrecognized Tax Benefits
	Three Months Ended March 31,				March 31,
	2015		2014		2015
					(In millions)
DTE Energy	31	%	33	%	$	9
DTE Electric	35	%	36	%	$	4

The 2% decrease in DTE Energy's effective tax rate for the three months ended March 31, 2015 is primarily due to the inclusion in 2014 of $8 million of deferred tax expense resulting from New York state income tax reform enacted in March 2014. The 1% decrease in DTE Electric's effective tax rate for the three months ended March 31, 2015 is due to higher production tax credits.

If recognized, $2 million of the unrecognized tax benefits of the Registrants would favorably impact their effective tax rates. DTE Energy believes that it is possible that there will be a decrease in the unrecognized tax benefits of up to $6 million in the next twelve months. DTE Electric does not anticipate any material changes to the unrecognized tax benefits in the next twelve months.

DTE Electric had an income tax receivable with DTE Energy of $51 million and $29 million at March 31, 2015 and December 31, 2014, respectively.
