Lessor Arrangements

We lease real estate properties, comprised primarily of office properties and data center shells, to third parties. These leases encompass all, or a portion, of properties, with various expiration dates. Our lease revenue is comprised of: fixed-lease revenue, including contractual rent billings under leases recognized on a straight-line basis over lease terms and amortization of lease incentives and above- and below-market lease intangibles; and variable-lease revenue, including tenant expense recoveries, lease termination revenue and other revenue from tenants that is not fixed under leases. The table below sets forth our composition of lease revenue recognized between fixed- and variable-lease revenue (in thousands):

A significant concentration of our lease revenue from continuing operations was earned from our largest tenant, the USG, including 37% in 2023 and 2022 and 36% in 2021 of our total lease revenue, and 27% in 2023 and 2022 and 26% in 2021 of our fixed-lease revenue. Our lease revenue from the USG in 2023, 2022 and 2021 was earned primarily from properties in the Fort George G. Meade and the Baltimore/Washington Corridor (“Fort Meade/BW Corridor”), Lackland Air Force Base and Northern Virginia Defense/IT (“NoVA Defense/IT”) reportable sub-segments (see Note 13).

As of December 31, 2023, our balance sheet included $43.9 million in right-of-use assets associated primarily with land leased from third parties underlying certain properties that we are operating. The land leases have long durations with remaining terms ranging from 25 to 77 years (excluding extension options). As of December 31, 2023, our right-of-use assets included:

>$14.5 million for land in a business park in Huntsville, Alabama under 20 leases through our LW Redstone Company, LLC joint venture, with remaining terms ranging from 39 to 50 years and options to renew for an additional 25 years that were not included in the term used in determining the asset balance;

>$6.4 million for land underlying a parking garage in Baltimore, Maryland under a lease with a remaining term of 25 years and an option to renew for an additional 49 years that was included in the term used in determining the asset balance;
