Note 18.	Commitments and Contingencies

Commitments. We have commitments for future payments related to office facilities leases. We lease office facilities under various operating leases expiring through 2024. Future minimum payments as of December 31, 2018 are as follows (in thousands):



	Office Leases
2019	$	3,744
2020	3,049
2021	2,722
2022	2,424
2023	2,348
Thereafter	1,634
Total minimum payments (a)	$	15,921

(a) Total minimum payments exclude executory costs, inclusive of insurance, maintenance, and taxes, of $6.2 million; minimum payments also have not been reduced by sublease rentals of $6.0 million due in the future under noncancelable subleases.

Rent expense during the years ended December 31, 2018, 2017, and 2016, was $2.8 million, $3.0 million, and $4.2 million, respectively.

As discussed in Note 5. Napster Joint Venture, in late 2017, we entered into an arrangement whereby we may be required to guarantee up to $2.75 million of Napster's outstanding indebtedness on their revolving credit facility. As of the date of this filing, we have not been required to pay any portion of this commitment. For additional details, refer to Note 22. Subsequent Event.

We could in the future become subject to legal proceedings, governmental investigations and claims in the ordinary course of business, including employment claims, contract-related claims, and claims of alleged infringement of third-party patents, trademarks and other intellectual property rights. Such claims, even if not meritorious, could force us to expend significant financial and managerial resources. In addition, given the broad distribution of some of our consumer products, any individual claim related to those products could give rise to liabilities that may be material to us. In the event of a determination adverse to us, we may incur substantial monetary liability, and/or be required to change our business practices. Either of these could have a material adverse effect on our consolidated financial statements.
