Future Minimum Lease Payments Under Non-Cancelable Operating Leases

uture minimum lease payments under non-cancellable operating leases (with an initial or remaining lease terms in excess of one year) are as follows (amounts in thousands):

Year Ending December 31,	Operating Leases
2019	$	8,488
2020	6,139
2021	5,477
2022	2,649
2023	883
Thereafter	61
Total minimum lease payments	$	23,697

Our other noncurrent liabilities in the consolidated balance sheet include unrecognized tax benefits. As of December 31, 2018, we had gross unrecognized tax benefits of $1.9 million. At this time, we are unable to make a reasonably reliable estimate of the timing of payments in individual years in connection with these tax liabilities; therefore, such amounts are not included in the above contractual obligation table.
