Commitments and Contingencies Commitments We lease facilities for our corporate office, sales centers, vehicles and equipment under operating leases that expire in various years through 2027. Most of our leases contain renewal options, some of which involve rate increases. For leases with step rent provisions whereby the rental payments increase incrementally over the life of the lease, we recognize the total minimum lease payments on a straight-line basis over the minimum lease term. The table below presents rent expenses associated with operating leases for the past three years (in thousands): 2014 2013 2012 $ 60,214 $ 58,188 $ 59,873 The table below sets forth the approximate future minimum lease payments as of December 31, 2014 related to non-cancelable operating leases and the non-cancelable portion of certain vehicle operating leases with initial terms of one year or more (in thousands): 2015 $ 40,296 2016 36,344 2017 27,629 2018 19,669 2019 12,800 Thereafter 12,862 Contingencies From time to time, we are subject to various claims and litigation arising in the ordinary course of business, including product liability, personal injury, commercial, contract and employment matters. Each quarter, we evaluate developments related to claims and litigation and record a liability if we deem a loss to be probable and estimable. When evaluating these matters for accrual and disclosure, we consider factors such as historical experience, specific facts and claims asserted, the likelihood we will prevail and the magnitude of any potential loss. The outcome of any litigation is inherently unpredictable. Based on currently available facts, we do not believe that the ultimate resolution of any of these claims and litigation matters will have a material adverse impact on our financial condition, results of operations or cash flows. We do not believe our exposure for any of these matters is material for disclosure, either individually or in the aggregate.
