Represents the write-off of lease incentives related to two properties due to negotiations to transition these properties to another operator in our portfolio that never materialized.

Non-contingent lease incentives represent payments made to our lessees for various reasons including entering into a new lease or lease amendments and extensions. Contingent lease incentives represent potential contingent earn-out payments that may be made to our lessees in the future, as part of our lease agreements. From time to time, we may commit to provide contingent payments to our lessees, upon our properties achieving certain rent coverage ratios. Once the contingent payment becomes probable and estimable, the contingent payment is recorded as a lease incentive. Lease incentives are amortized as a yield adjustment to rental income over the remaining life of the lease.
