Note 15. Leases

Our operating lease activities consist of leases for office space and equipment. Our finance lease activities consist of leases for hardware which we will own at the end of the lease agreement. None of our lease agreements include variable lease payments. See the discussion of our January 1, 2019 implementation of a new accounting standard for leases and its impact on our Consolidated Financial Statements at Note 2. New Accounting Standards.
