Commitments and Contingencies Disclosure [Abstract]

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, 2016, are as follows (in thousands):



Year Ending December 31,
2017	$	12,768
2018	9,039
2019	4,984
2020	4,315
2021	3,676
Thereafter	13,094
Total future lease commitments	$	47,876

Total rent expense incurred under operating leases was $19.1 million, $19.6 million, and $17.2 million for the years ended December 31, 2016, 2015 and 2014, respectively.

We also have purchase commitments for inventory in the amount of $8.5 million. We enter into purchase commitments as needed.

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, 2016, 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.

We are conducting an internal investigation of the operations of certain of our foreign subsidiaries in West Africa including possible violations of the U.S. Foreign Corrupt Practices Act ("FCPA"), our policies and other applicable laws. In June 2016, we voluntarily disclosed the existence of our internal review to the U.S. Securities and Exchange Commission, the United States Department of Justice and other governmental entities. While our review does not currently indicate that there has been any material impact on our previously filed financial statements, we continue to collect information and are unable to predict the ultimate resolution of these matters with these agencies.
