COMMITMENTS AND CONTINGENCIES

Operating Leases and Other Commitments

The Company’s principal facilities are leased under various cancelable and non-cancelable operating leases that expire at various dates through 2027. For tenant improvement allowances and rent holidays, Trimble records a deferred rent liability on the Consolidated Balance Sheets and amortizes the deferred rent over the terms of the leases as reductions to rent expense on the Consolidated Statements of Income.

The estimated future minimum payments required under the Company’s operating lease commitments at the end of fiscal 2018 were as follows (in millions):



2019	$	42.7
2020	33.1
2021	25.3
2022	21.6
2023	17.5
Thereafter	26.9
Total	$	167.1

Net rent expense under operating leases was $42.1 million in fiscal 2018, $35.5 million in fiscal 2017, and $34.4 million in fiscal 2016.

At the end of fiscal 2018, the Company had unconditional purchase obligations of approximately $269.0 million. These unconditional purchase obligations primarily represent open non-cancelable purchase orders for material purchases with the Company’s vendors. Purchase obligations exclude agreements that are cancelable without penalty.

Additionally, the Company has certain acquisitions that include additional earn-out cash payments based on estimated future revenues, gross margins, or other milestones. At the end of fiscal 2018, the Company had $5.6 million included in Other current liabilities of $0.1 million and Other non-current liabilities of $5.5 million related to these earn-outs, representing the fair value of the contingent consideration.

Litigation

From time to time, the Company is involved in litigation arising out of the ordinary course of its business. There are no material legal proceedings, other than ordinary routine litigation incidental to the business, to which the Company or any of its subsidiaries is a party or of which any of the Company's or its subsidiaries' property is subject.
