Commitments and Contingencies Litigation We are involved from time-to-time in various legal proceedings that arise in the ordinary course of our business, including, but not limited to commercial disputes, environmental matters, and litigation in connection with transactions including acquisitions and divestitures. We believe that such litigation, claims and administrative proceedings will not have a material adverse impact on our financial position or our results of operations. We record a liability when a loss is considered probable and the amount can be reasonably estimated. Concentration of Credit Risk Our properties rely heavily upon anchor or major tenants to attract customers; however, these retailers do not constitute a material portion of our financial results. Additionally, many anchor retailers in the enclosed retail properties own their spaces further reducing their contribution to our operating results. All operations are within the United States and no customer or tenant accounts for 5% or more of our consolidated revenues. Lease Commitments As of March 31, 2019 , a total of four consolidated properties are subject to ground leases. The termination dates of these ground leases range from 2026 to 2076. These ground leases generally require us to make fixed annual rental payments, or a fixed annual rental plus a percentage rent component based upon the revenues or total sales of the property. Some of these leases also include escalation clauses and renewal options. We incurred ground lease expense, which is included in ground rent in the accompanying consolidated statements of operations and comprehensive (loss) income, for the three months ended March 31, 2019 and 2018 of $203 and $197 , respectively, of which $5 and $13 related to straight-line rent expense, respectively. Additionally, the Company has two material office leases and one material garage lease. The termination dates of these leases range from 2023 to 2026. These leases generally require us to make fixed annual rental payments, plus our share of CAM expense and real estate taxes and insurance. We incurred lease expense, which is included in general and administrative expenses in the accompanying consolidated statements of operations and comprehensive (loss) income, for the three months ended March 31, 2019 and 2018 of $631 and $833 , respectively. On January 1, 2019, we recorded a lease liability and corresponding ROU asset of approximately $14.4 million . The weighted average remaining lease term for our consolidated operating leases was 18.5 years and the weighted average discount rate for determining the lease liabilities was 8.67% at January 1, 2019. The discount rates utilized in calculating the lease liabilities represents our estimate of the Company's incremental borrowing rate over the terms that correspond to the leases. Future minimum lease payments due under these leases for each of the next five years and thereafter, excluding applicable extension options, as of March 31, 2019 are as follows: 2019 $ 1,523 2020 2,049 2021 2,069 2022 2,099 2023 1,427 Thereafter 21,377 Total lease payments 30,544 Less: Discount 16,507 Present value of lease liabilities $ 14,037 The weighted average remaining lease term for our consolidated operating leases was 18.6 years and the weighted average discount rate for determining the lease liabilities was 8.68% at March 31, 2019 .
