We have operating leases for office space, laboratory operations, research and development facilities, manufacturing locations, warehouses and certain equipment. We determine if a contract contains a lease at inception or modification of a contract. Our leases generally do not provide an implicit interest rate, and we therefore use our incremental borrowing rate as the discount rate when measuring operating lease liabilities. The incremental borrowing rate represents an estimate of the interest rate we would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of the lease within a particular currency environment. We used the incremental borrowing rates as of January 1, 2019 for operating leases that commenced prior to that date. Many of our leases contain rental escalation, renewal options and/or termination options that are factored into our determination of lease payments as appropriate. Variable lease payment amounts that cannot be determined at the commencement of the lease are not included in the right-to-use assets or liabilities.
The following table presents the lease balances within the Condensed Consolidated Balance Sheet as of June 30, 2020:
The following table reconciles the undiscounted future minimum lease payments (displayed by year and in the aggregate) under noncancelable operating leases with terms of more than one year to the total operating lease liabilities recognized on our Condensed Consolidated Balance Sheet as of June 30, 2020:
Expense under operating leases and finance leases was $9.7 million and $1.2 million, respectively, for the six months ended June 30, 2020, which includes $1.6 million of variable lease costs. Expense under operating leases and finance leases was $9.8 million and $2.0 million, respectively, for the six months ended June 30, 2019, which includes $1.7 million of variable lease costs.
