Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Other Intangible Assets

We had no changes to the carrying amount of goodwill during the years ended December 31, 2014, and 2013. In the second quarter of 2014, we completed our annual goodwill impairment test, and no impairment resulted from this test.

Our intangible assets listed below consist of contractual service agreements that provide for major maintenance and protection against unforeseen maintenance costs related to the combustion turbine generators at the Fox Energy Center. These contractual service agreements are included in other long-term assets on the balance sheets.



	December 31, 2014							December 31, 2013
(Millions)	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount
Amortized intangible assets
Contractual service agreements	$	15.6	$	(4.3	)	$	11.3	$	15.6	$	(1.8	)	$	13.8

In October 2014, we received approval from the PSCW to upgrade the combustion turbine generators at the Fox Energy Center earlier than planned. As a result of this approval, we shortened the amortization period of one of our service agreements. The remaining weighted-average amortization period for these intangible assets at December 31, 2014, was approximately four years. Since we have approval from the PSCW to recover the value of our service agreements from customers over seven years, the increase in amortization due to the shorter amortization period is recorded to a regulatory asset. This regulatory asset will be amortized to reflect the seven-year recovery period.

The table below shows the amortization recorded during the years ended December 31:



(Millions)	2014		2013
Amortization recorded in depreciation and amortization expense	$	2.2	$	1.8
Amortization recorded in regulatory assets	0.3		—

Amortization for the next five years is estimated to be:
