Leases [Abstract]  
Leases Leases
Beginning October 1, 2019, we identify contracts that are or contain leases where a contract allows us the right to control identified property or equipment for a period of time in return for consideration. Our leases are typically for office space or facilities, as well as some equipment leases. Where contracts include both lease and non-lease components, we do not typically separate the non-lease components in our accounting.
At the inception of a lease, we recognize a liability for future minimum lease payments based upon the present value of those payments.
In identifying our future minimum lease payments, we do not include variable lease costs, such as those for maintenance or utilities. These are recorded as lease expenses in the period in which they are incurred.
In identifying future lease payments, we do not include short-term leases, identified as those with an initial term of twelve months or less.
Lease options are included within our lease liability only where it is reasonably certain that we will utilize those periods of the lease and incur the related costs.
In calculating the fair value of our lease liability, we utilize an estimate of our collateralized incremental borrowing rate. This estimate is based upon publicly-available information adjusted for company-specific, country-specific and lease-specific factors. The weighted average incremental borrowing rate utilized at September 30, 2020, is 3.8%.
Over the course of a lease, the lease liability is reduced as scheduled lease payments are made and increased as the implied interest charges are added.
Our right-of-use asset is based upon the lease liability at the contract inception but is adjusted over the life of the lease by lease prepayments, additional costs or lease incentives. The right-of-use asset is amortized on a straight-line basis over the lease term, offset by the interest accretion recorded on the lease liability.
Lease expense is recorded within our consolidated statements of operations based upon the nature of the assets. Where assets are used to directly serve our customers, such as facilities dedicated to customer contracts, lease costs are recorded in "cost of revenue." Facilities and assets which serve management and support functions are expensed through "selling, general and administrative expenses." Costs recorded for the year ended September 30, 2020, are summarized below.
