Commitments and Contingencies Disclosure [Abstract] |
COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES EMPLOYEE BENEFIT PLANS. We offer a defined contribution plan, which qualifies under section 401(k) of the Internal Revenue Code and covers all eligible U.S. employees. We can also elect to make matching contributions to the plan. Annual discretionary contributions may also be made to the plan. Defined contribution plan expense, including matching contributions, was approximately (in thousands):
2017 | $ | 27,530 |
2016 | 25,740 |
2015 | 46,507 |
We have committed to a defined contribution match of four percent of eligible compensation in 2018. We contributed a defined contribution match of four percent in 2017, 2016, and 2015. NONQUALIFIED DEFERRED COMPENSATION PLAN. All restricted shares vested but not yet delivered, as well as a deferred share award granted to our CEO, are held within this plan. LEASE COMMITMENTS. We lease certain facilities and equipment under operating leases. Information regarding our lease expense is as follows (in thousands):
2017 | $ | 60,864 |
2016 | 55,170 |
2015 | 56,210 |
Minimum future lease commitments under noncancelable lease agreements in excess of one year as of December 31, 2017, are as follows (in thousands):
2018 | $ | 51,273 |
2019 | 46,172 |
2020 | 39,825 |
2021 | 29,851 |
2022 | 22,807 |
Thereafter | 92,797 |
Total | $ | 282,725 |
In addition to minimum lease payments, we are typically responsible under our lease agreements to pay our pro rata share of maintenance expenses, common charges, and real estate taxes of the buildings in which we lease space. LITIGATION. We are not subject to any pending or threatened litigation other than routine litigation arising in the ordinary course of our business operations, including 16 contingent auto liability cases as of December 31, 2017. For some legal proceedings, we have accrued an amount that reflects the aggregate liability deemed probable and estimable, but this amount is not material to our consolidated financial position, results of operations, or cash flows. Because of the preliminary nature of many of these proceedings, the difficulty in ascertaining the applicable facts relating to many of these proceedings, the inconsistent treatment of claims made in many of these proceedings, and the difficulty of predicting the settlement value of many of these proceedings, we are not able to estimate an amount or range of any reasonably possible additional losses. However, based upon our historical experience, the resolution of these proceedings is not expected to have a material effect on our consolidated financial position, results of operations, or cash flows.
