Commitments and Contingencies [Abstract]

12. Commitments and Contingencies

From time to time the Company is involved in legal proceedings, claims and litigation related to employee claims, contractual disputes and taxes in the ordinary course of business. Although the Company cannot predict the outcome of such matters, currently the Company has no reason to believe the disposition of any current matter could reasonably be expected to have a material adverse impact on the Company's financial position, results of operations or the ability to carry on any of its business activities.

In June 2016, the Company entered into an agreement to purchase software licenses for internal use payable over a two-year period. As a result, the Company has recorded $0.8 million in "Other current liabilities" in the Consolidated Balance Sheet as of December 31, 2017.

Certain of the Company's operating leases contain predetermined fixed escalations of minimum rentals during the original lease terms. For these leases, the Company recognizes the related rental expense on a straight-line basis over the life of the lease and records the difference between the amounts charged to operations and amounts paid as accrued rent expense.

The Company leases office space and certain equipment under various operating lease agreements. The Company has the option to extend the term of certain lease agreements. Future minimum commitments under these lease agreements as of December 31, 2017 are as follows (in thousands):

	Operating Leases
2018	$	6,535
2019		6,539
2020		6,072
2021		4,595
2022		2,773
Thereafter		2,970
Total minimum lease payments	$	29,484

Rent expense for the years ended December 31, 2017, 2016, and 2015 was approximately $7.9 million, $7.5 million, and $6.5 million, respectively.
