Summary of Significant Accounting Policies [Abstract]

Current and prior residual values and depreciable lives for each type of equipment

The Company depreciates its rental equipment over its estimated useful life to its estimated fixed residual value using the straight line method of depreciation. During the first quarter of 2012, the Company completed a review of historical disposal experience relating to its fleet of container equipment and concluded that the estimated residual values and depreciable lives used in its depreciation calculations should be amended effective January 1, 2012. The following table shows the current and prior residual values and depreciable lives that the Company adopted for each type of equipment:

	Residual Value				Depreciable Life in Years
	Current		Prior		Current		Prior
20-ft. standard dry van container	$	1,050	$	950		13.0		12.5
40-ft. standard dry van container	$	1,300	$	1,150		13.0		12.5
40-ft. high cube dry van container	$	1,650	$	1,300		13.0		12.5
20-ft. refrigerated container	$	2,750	$	2,250		12.0		12.0
40-ft. high cube refrigerated container	$	3,500	$	3,000		12.0		12.0

Estimated useful lives

Intangible assets with definite useful lives are reviewed for impairment whenever events or changes in circumstances indicate an asset's carrying value may not be recoverable. The Company currently amortizes intangible assets on a straight-line basis over their estimated useful lives as follows:

Trademarks	1-10 years
Contracts-third party	7 years
Contracts and customer relationships-owned equipment	5-7 years
