The Company implemented ASC Topic 842, Leases, effective January 1, 2019 (Note 1). As lessor, there were no accounting adjustments required, however, the presentation of the Company’s lease revenues in 2019 includes amounts previously reported as reimbursed expenses. There was no cumulative effect adjustment to retained earnings required upon adoption of the new standard. In addition, the Company began expensing internal leasing costs, which have historically been capitalized.

The Company is engaged in the operation of shopping centers and other retail properties that are either owned or, with respect to certain shopping centers, operated under long-term ground leases (see below) that expire at various dates through June 20, 2066, with renewal options. Space in the shopping centers is leased to tenants pursuant to agreements that provide for terms ranging generally from one month to sixty years and generally provide for additional rents based on certain operating expenses as well as tenants’ sales volumes. During the three months ended March 31, 2019, the Company earned $13.3 million in variable lease revenues, primarily for real estate taxes and common area maintenance charges, which are included in lease revenues in the consolidated statements of income.

As lessee, upon implementation of ASC Topic 842, the Company recorded right-of-use assets and corresponding lease liabilities of $11.9 million and $12.8 million, respectively, for nine existing operating leases (for ground, office and equipment leases) and $82.6 million and $76.6 million, respectively, for four finance leases related to ground rentals including an existing capital lease which represented $77.0 million and $71.1 million, respectively, of the total. Three finance leases were recorded post-implementation upon assessment of triggering events whereby the Company’s cumulative leasehold investment made it reasonably certain that the Company would exercise its purchase options.

A ground lease expiring during 2078 provides the Company with an option to purchase the underlying land during 2031. If the Company does not exercise the option, the rents that will be due are based on future values and as such are not determinable at this time. Accordingly, the above table does not include rents for this lease beyond 2031.

During the three months ended March 31, 2019 and 2018, no single tenant collectively comprised more than 10% of the Company’s consolidated total revenues.
