Property, Plant and Equipment [Abstract]


Note 6.	Property, Plant and Equipment

Property, plant and equipment consists primarily of network equipment and other long-lived assets used to provide service to our subscribers. In the first quarter 2012, we formalized our plans to take off-air roughly one-third, or 9,600 cell sites, of our total Nextel platform by the middle of 2012 with the remaining sites to be taken off-air by June 30, 2013. As a result, in the first quarter 2012, we revised our estimates to shorten the expected useful lives of Nextel platform assets through 2013, the expected benefit period of the underlying assets, and also revised the expected timing and amount of our asset retirement obligations. During the second quarter 2012, as a result of our progress in taking Nextel platform sites off-air and our progress toward notifying and transitioning customers off the Nextel platform, we further reduced our estimated benefit period for the remaining Nextel platform assets through the middle of 2013 resulting in incremental depreciation expense during the period. The amounts reflected as depreciation expense are dependent upon the expected useful lives of assets, which includes our expectation of the timing of assets to be phased out of service, and could result in further revision during the decommissioning period. In addition, increasing data usage driven by more subscribers on the Sprint platform and a continuing shift in our subscriber base to smartphones is expected to require additional legacy 3G Sprint platform equipment that will not be utilized beyond the final deployment of Network Vision's multi-mode technology, which began in 2011 and is expected to continue through the middle of 2014. As a result, the estimated useful lives of such equipment will be shortened, as compared to similar prior capital expenditures, through the date on which Network Vision equipment is deployed and in-service. The incremental effect of accelerated depreciation expense totaled approximately $2.1 billion for the year ended December 31, 2012, of which the majority related to shortened useful lives of Nextel platform assets.

In connection with Network Vision, a substantial portion of the value of certain spectrum licenses that were not previously placed in service are now ready for their intended use. As qualifying activities are performed related to Network Vision, interest expense primarily related to the carrying value of these spectrum licenses is being capitalized to construction in progress within property, plant and equipment, which ceases as the spectrum is ready for its intended use. Interest expense capitalized in connection with the construction of long-lived assets totaled $278 million, $413 million and $13 million for the years ended December 31, 2012, 2011 and 2010, respectively. Construction in progress (including any capitalized interest) associated with Network Vision is expected to be depreciated using the straight-line method over a weighted average useful life of approximately eight years, once the assets are placed in service.

The components of property, plant and equipment, and the related accumulated depreciation were as follows:



	December 31, 2012			December 31, 2011
	(in millions)
Land	$	330		$	333
Network equipment, site costs and related software	37,692			37,600
Buildings and improvements	4,893			4,895
Non-network internal use software, office equipment and other	1,860			2,111
Construction in progress	3,123			1,752
Less accumulated depreciation	(34,291		)	(32,682		)
Property, plant and equipment, net	$	13,607		$	14,009
