For a detailed discussion about Newmark’s significant accounting policies, See Note 3 — “Summary of Significant Accounting Policies,” in Newmark’s consolidated financial statements included in Part II, Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. Other than the following, during the three and nine months ended September 30, 2019, there were no significant changes made to Newmark’s significant accounting policies.

Newmark, acting as a lessee, has operating leases primarily relating to office space. The leases have remaining lease terms of up to 1 year to 13 years, some of which include options to extend the leases in 5 to 10 year increments for up to 10 years. Renewal periods are included in the lease term only when renewal is reasonably certain, which is a high threshold and requires management to apply judgment to determine the appropriate lease term. Certain leases also include periods covered by an option to terminate the lease if Newmark is reasonably certain not to exercise the termination option. Newmark measures its lease payments by including fixed rental payments and, where relevant, variable rental payments tied to an index, such as the Consumer Price Index. Payments for leases in place before the date of adoption of ASC 842, Leases were determined based on previous leases guidance. Newmark recognizes lease expense for its operating leases on a straight-line basis over the lease term and variable lease expense not included in the lease payment measurement is recognized as incurred. All leases were classified as operating leases as of September 30, 2019.

Pursuant to the accounting policy election, leases with an initial term of twelve months or less are not recognized on the balance sheet. The short-term lease expense over the period reasonably reflects Newmark’s short-term lease commitments.

ASC 842, Leases requires Newmark to make certain assumptions and judgments in applying the guidance, including determining whether an arrangement includes a lease, determining the term of a lease when the contract has renewal or cancelation provisions, and determining the discount rate.

Newmark determines whether an arrangement is a lease or includes a lease at the contract inception by evaluating whether the contract conveys the right to the control of the use of an identified asset for a period of time in exchange for consideration. If Newmark has the right to obtain substantially all of the economic benefits from, and can direct the use of, the identified asset for a period of time, Newmark accounts for the identified asset as a lease. Newmark has elected the practical expedient to not separate lease and non-lease components for all leases other than real estate leases. The primary non-lease component that is combined with a lease component represents operating expenses such as utilities, maintenance or management fees.

As the rate implicit in the lease is not usually available, Newmark used an incremental borrowing rate based on the information available at the adoption date of the new leases standard in determining the present value of lease payments for existing leases. Newmark will use information available at the lease commencement date to determine the discount rate for any new leases.

Newmark has a single operating segment. Newmark is a real estate services firm offering services to commercial real estate tenants, owner occupiers, investors and developers, leasing and corporate advisory, investment sales and real estate finance, consulting, origination and servicing of commercial mortgage loans, valuation, project and development management and property and facility management. The chief operating decision maker regardless of geographic location evaluates the operating results of Newmark as total real estate services and allocates resources accordingly.
