Note 17.	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, 2017 are as follows (in thousands):



	Office Leases
2018	$	5,373
2019	5,067
2020	4,564
2021	4,379
2022	4,054
Thereafter	6,501
Total minimum payments (a)	$	29,938

(a) Minimum payments have not been reduced by minimum sublease rentals of $10.7 million due in the future under noncancelable subleases.

Of the total office lease future minimum payments, $2.1 million is recorded in accrued lease exit and related charges at December 31, 2017.

Rent expense during the years ended December 31, 2017, 2016, and 2015, was $3.0 million, $4.2 million, and $5.8 million, respectively.

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 4. Napster Joint Venture.

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.
