Leases

3 Months Ended

Operating leases

We lease office space under operating leases that expire between 2026 and 2034. The terms of the leases provide for rental payments on a graduated scale, options to renew the leases (one to five years), landlord incentives or allowances, and periods of free rent. We have subleased portions of our corporate headquarters to various sublessees with subleases commencing at various dates between 2021 and 2026.

Components of lease expense (income) are summarized as follows (in thousands):


	Three Months Ended March 31,
	2026		2025
	(unaudited)
Operating lease expense	$	583	$	769
Short-term lease expense	41		155
Sublease income	(558)		(500)
Total	$	66	$	424

We also incur immaterial variable costs related to our leased office space, such as maintenance and utilities based on actual usage, which are not included in the measurement of right-of-use assets and lease liabilities, but are expensed as incurred.

During the three months ended March 31, 2026 and 2025, we did not identify asset impairment indicators for our corporate office spaces designated for subleasing, and therefore did not recognize any impairment charges.
