The Company’s leases primarily consist of noncancellable operating leases for office space with contractual terms expiring from 2022 to 2027. All of our leases are operating leases and, as a lessee, we have not entered into any sublease agreements. The lease term is defined as the fixed noncancellable term of the lease plus all periods, if any, for which failure to renew the lease imposes a penalty on us in an amount that appears, at the inception of the lease, to be reasonably assured. While some of our leases include an option to extend the lease up to five years, it is not reasonably certain that any such options will be exercised due, in part, to the dynamic nature of our sales force and rate of growth. Some of our leases contain termination options that are not reasonably certain to be exercised. If a renewal or termination option is exercised, we remeasure the lease asset in the consolidated balance sheets using the updated lease period. None of our leases contain residual value guarantees, substantial restrictions or covenants.

The table below presents the lease assets and liabilities as of December 31, 2021 and December 31, 2020.

Balance Sheet location	December 31, 2021		December 31, 2020
Other assets	$	29,841	$	26,481
Lease liabilities:
Accrued expenses and other current liabilities	$	10,853	$	10,906
Other long-term liabilities	$	20,059	$	16,990

Rent expense under operating leases for the years ended December 31, 2021, 2020 and 2019 was $11.9 million, $11.3 million and $10.1 million, respectively. Cash paid for amounts relating to our operating leases was $13.3 million for the year ended December 31, 2021.

Because no implicit discount rates for our leases could be readily determined, we elected to use an estimated incremental borrowing rate to determine the present value of our leases. The weighted average discount rate related to our portfolio of leases at December 31, 2021 was 3.3%. The average remaining lease term for our leases was 2.8 years as of December 31, 2021.

The undiscounted cash flows for the future annual maturities of our operating lease liabilities and the reconciliation of those total undiscounted cash flows to our lease liabilities as of December 31, 2021 were as follows:

2022	$	11,069
2023		9,160
2024		5,954
2025		3,082
2026		1,490
Thereafter		2,204
Total undiscounted cash flows	$	32,959
Present value discount		(2,047	)
Lease liabilities	$	30,912

The table above does not include any legally binding minimum lease payments for leases signed but not yet commenced. As of December 31, 2021, the present value of the operating lease liabilities that had not yet commenced was $1.9 million.
