Commitments and Contingencies

13. Commitments and Contingencies

We lease office and warehouse facilities, vehicles and office equipment under operating lease agreements, which include both monthly and longer-term arrangements. Leases with initial terms of one year or more expire at various dates through 2020 and generally provide for extension options. Rent expense under the leasing agreements (exclusive of real estate taxes, insurance and other expenses payable under the leases) amounted to $17,524, $17,375 and $16,215 in 2012, 2011 and 2010, respectively.

The minimum rentals for aggregate lease commitments as of December 31, 2012, were as follows:

2013	$	8,469
2014	4,252
2015	2,555
2016	1,247
2017	209
Thereafter	89
Total	$	16,821

Certain operating leases for vehicles contain residual value guarantee provisions, which would become due at the expiration of the operating lease agreement if the fair value of the leased vehicles is less than the guaranteed residual value. The aggregate residual value at lease expiration of those leases is $11,334, of which we have guaranteed $7,231. As of December 31, 2012, we have recorded a liability for the estimated end-of-term loss related to this residual value guarantee of $536 for certain vehicles within our fleet. Our fleet also contains vehicles we estimate will settle at a gain. Gains on these vehicles will be recognized at the end of the lease term.

During the second quarter of 2012, we entered into a three year agreement with a supplier, commencing January 1, 2013, with a total commitment of $2,102 which is still outstanding as of December 31, 2012.

In the ordinary course of business, we may become liable with respect to pending and threatened litigation, tax, environmental and other matters. While the ultimate results of current claims, investigations and lawsuits involving us are unknown at this time, we do not expect that these matters will have a material adverse effect on our consolidated financial position or results of operations. Legal costs associated with such matters are expensed as incurred.
