COMMITMENTS AND CONTINGENCIES

Contractual Obligations

We had no significant commitments and contractual obligations as of December 31, 2018.

Other Commitments

We have various LOCs outstanding with multiple state agencies which are considered to be immaterial to the consolidated financial statements. The LOCs typically have one to three-year contract requirements and contain automatic renewal terms.

Legal Contingencies

We are involved, from time to time, in lawsuits arising in the normal course of business. We believe these pending lawsuits will not have a material adverse impact on our financial position or statement of operations. There have been no material changes during the twelve months ended December 31, 2018 to the commitments and contingencies previously reported in the 2017 Annual Report and our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2018.

Operating Leases

We have operating leases for office and transmitter locations. Substantially all of these leases have lease terms ranging from one month to five years. We continue to review our office and transmitter locations, and intend to replace, reduce or consolidate leases, where possible.

Future minimum lease payments under non-cancelable operating leases at December 31, 2018 were as follows:



For the Year Ended December 31,	(Dollars in thousands)
2019	$	6,716
2020	5,058
2021	4,102
2022	2,327
2023	1,586
Thereafter	424
Total	$	20,213

These leases typically include renewal options and escalation clauses. Where material, we recognize rent expense on a straight-line basis over the lease period. The difference between rent paid and rent expense is recorded as other current liabilities and other non-current liabilities on the consolidated balance sheets.

Total rent expense under operating leases for the years ended December 31, 2018, 2017 and 2016, was approximately $17.5 million, $17.7 million and $17.9 million, respectively.
