Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Commitments and Contingencies Commitments We are committed under various noncancelable operating lease agreements primarily related to facilities and equipment that expire at various dates throughout the next several years. Future minimum lease commitments under noncancelable operating leases with initial or remaining terms of one year or more at December 31, 2015, are as follows (in thousands):
| Year Ending December 31, |  |
| 2016 | $ | 11,575 |  |
| 2017 | 9,773 |  |
| 2018 | 7,220 |  |
| 2019 | 3,870 |  |
| 2020 | 3,767 |  |
| Thereafter | 16,673 |  |
| Total future lease commitments | $ | 52,878 |  |
Total rent expense incurred under operating leases was $19.6 million, $17.2 million, and $12.9 million for the years ended December 31, 2015, 2014 and 2013, respectively. Contingencies We are the subject of lawsuits and claims arising in the ordinary course of business from time to time. A liability is accrued when a loss is both probable and can be reasonable estimated. As of December 31, 2015, we had no material accruals for loss contingencies, individually or in the aggregate. We believe the probability is remote that the ultimate outcome of these matters would have a material adverse effect on our financial position, results of operations or cash flows.
