Leases [Abstract] |
Leases | Leases Lessor Arrangements We lease real estate properties, comprised primarily of office properties and data center shells, to third parties. As of December 31, 2020, these leases, which may encompass all, or a portion of, a property, had remaining terms spanning from one month to 18 years and averaging approximately 5.4 years. 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 the lease. 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 in 2020 and 2019 was earned from our largest tenant, the USG, including 35% and 34% of our total lease revenue, respectively, and 25% of our fixed lease revenue in each of those years. Our lease revenue from the USG in 2020 and 2019 was earned primarily from properties in the Fort Meade/BW Corridor, Lackland Air Force Base and Northern Virginia Defense/IT reportable sub-segments (see Note 17). Fixed contractual payments due under our property leases were as follows (in thousands):

Lessee Arrangements As of December 31, 2020, our balance sheet included $81.0 million in right-of-use assets associated primarily with land leased from third parties underlying certain properties that we are operating or developing. The land leases have long durations with remaining terms ranging from 28 years (excluding extension options) to 95 years.

This lease has a 95-year remaining term, and we possess a bargain purchase option that we expect to exercise in 2021; •$11.3 million for land in a business park in Huntsville, Alabama under 15 leases through our LW Redstone Company, LLC joint venture, with remaining terms ranging from 42 to 51 years and options to renew for an additional 25 years that were not included in the term used in determining the asset balance; •$10.1 million for land underlying operating office properties in Washington, D.C. under two leases with remaining terms of approximately 79 years; •$6.6 million for land in a research park in College Park, Maryland under four leases through our M Square Associates, LLC joint venture, all of the rent on which was previously paid.

Leases | Leases Lessor Arrangements We lease real estate properties, comprised primarily of office properties and data center shells, to third parties. As of December 31, 2020, these leases, which may encompass all, or a portion of, a property, had remaining terms spanning from one month to 18 years and averaging approximately 5.4 years. 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 the lease. The table below sets forth our composition of lease revenue recognized between fixed and variable lease revenue (in thousands):
