COMMITMENTS AND CONTINGENCIES

Leases – We lease buildings and equipment under non-cancellable operating leases through 2026. Some of these leases include cost-escalation clauses. Such cost-escalation clauses are recognized on a straight-line basis over the lease term. The following is a schedule of future minimum lease payments required under non-cancelable operating leases with initial terms in excess of one year, in effect at December 31, 2016:




Years ending December 31,	Amount
2017	$	6,620
2018	4,969
2019	3,604
2020	2,416
2021	1,237

Total future minimum lease payments	$	23,363

Rent expense for 2016, 2015, and 2014 was $7,720, $6,874 and $6,119, respectively.

Purchase Commitments — We enter into purchase commitments for products and services in the ordinary course of business. These purchases generally cover production requirements for 60 to 120 days as well as materials necessary to service customer units through the product lifecycle and for warranty commitments. As of December 31, 2016 we had approximately $29.4 million in purchase commitments that are expected to be delivered within the next 12 months. To ensure adequate component availability in preparation for new product introductions, as of December 31, 2016, we also had $30.3 million in long-term commitments for purchases to be delivered after 12 months.

Legal Proceedings — We are not involved in any legal proceedings other than routine litigation arising in the normal course of business, none of which we believe will have a material adverse effect on our business, financial condition or results of operations.
