Components of intangible assets

Our other intangibles assets, net at September 30, 2012 include the following assets associated with the 2012 acquisition of RSC discussed above (see note 2 to our condensed consolidated financial statements). No residual value has been assigned to these intangible assets. The non-compete agreements are being amortized on a straight-line basis, and the customer relationships and trade names, associated trademarks and other are being amortized using the sum of the years' digits method, which we believe best reflects the estimated pattern in which the economic benefits will be consumed.

	Weighted-Average Initial Amortization Period	Net Carrying Amount
Non-compete agreements	60 months	$	44
Customer relationships	15 years	1,052
Trade names, associated trademarks and other	60 months	70
