[1] Reflects certain ground leases, in which we are the lessee, that have longer initial fixed terms than our existing sublease to our tenants. However, we would expect to either renew the related sublease, enter into a lease with a new tenant, or early terminate the ground lease to reduce or avoid any significant impact from such ground leases.
