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 $17,873, $17,524 and $17,375 in 2013, 2012 and 2011, respectively. The minimum rentals for aggregate lease commitments as of December 31, 2013, were as follows:
2014 | $ | 8,398 |
2015 | 5,378 |
2016 | 3,129 |
2017 | 1,892 |
2018 | 778 |
Thereafter | 311 |
Total | $ | 19,886 |
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 $11,741, of which we have guaranteed $7,659. As of December 31, 2013, we have recorded a liability for the estimated end-of-term loss related to this residual value guarantee of $398 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 first quarter of 2013, we renewed our lease for our Louisville facility. This lease has a five year term with a total commitment of $4,710. 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 of which $1,306 remains outstanding as of December 31, 2013. 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.
