7. leases

We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liability and noncurrent operating lease liability in our condensed consolidated balance sheet as of June 30, 2019. The Company does not have any finance leases.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term.

We use our estimated incremental borrowing rates, which are derived from information available at the lease commencement date, in determining the present value of lease payments. For leases in existence at the adoption of ASC 842, we used the incremental borrowing rate as of January 1, 2019. We give consideration to our bank financing arrangements, geographical location and collateralization of assets when calculating our incremental borrowing rates.

Our lease terms include options to extend the lease when it is reasonably certain that we will exercise that option. Leases with a term of less than 12 months are not recorded in the condensed consolidated balance sheet. Our lease agreements do not contain any residual value guarantees. For real estate leases, we account for the lease and non-lease components as a single lease component. Some leases include escalation clauses and termination options that are factored in the determination of the lease payments when appropriate.

If a lease is modified after the effective date, the operating lease ROU asset and liability is re-measured using the current incremental borrowing rate.

We lease all of our facilities and some equipment. Lease expense is included in direct operating costs and general and administrative expenses in the condensed consolidated statements of operations based on the nature of the expense. As of June 30, 2019, we had 34 leased properties, five in Practice Management and 29 in Healthcare IT, with remaining terms ranging from less than one year to five years. Our lease terms are determined taking into account lease renewal options, the Company’s anticipated operating plans and leases that are on a month-to-month basis. We also have some related party leases – see Note 9.

Short-term lease cost represents leases that were not capitalized as the lease term as of the later of January 1, 2019 or the beginning of the lease was less than 12 months. Variable lease costs include utilities, real estate taxes and common area maintenance costs.
