We have operating lease agreements for our offices in the United States and India with lease periods expiring between 2020 and 2026. ASC 842 requires the recognition of leasing arrangements on the balance sheet as right-of-use assets and liabilities pertaining to the rights and obligations created by the leased assets. We determine whether an arrangement is a lease at inception and classify it as finance or operating. All of our existing material leases are classified as operating leases. Our leases do not contain any residual value guarantees.

Right-of-use lease assets and corresponding lease liabilities are recognized at commencement date based on the present value of lease payments over the expected lease term. Since the interest rate implicit in our lease arrangements is not readily determinable, we determine an incremental borrowing rate for each lease based on the approximate interest rate on a collateralized basis with similar remaining terms and payments as of the lease commencement date to determine the present value of future lease payments. Our lease terms may include options to extend or terminate the lease. Currently, it is not reasonably certain that we will exercise those options and therefore, we utilize the initial, noncancelable, lease term to calculate the lease assets and corresponding liabilities for all our leases. We have certain insignificant short-term leases with an initial term of twelve months or less that are not recorded in our consolidated balance sheets. Operating right-of-use lease assets are classified as operating lease assets on our consolidated balance sheets.

Our lease agreements generally contain lease and non-lease components. Non-lease components primarily include payments for maintenance and utilities. We have applied the practical expedient to combine fixed payments for non-lease components with our lease payments for all of our leases and account for them together as a single lease component, which increases the amount of our lease assets and corresponding liabilities. Payments under our lease arrangements are primarily fixed, however, certain lease agreements contain variable payments, which are expensed as incurred and not included in the operating lease assets and liabilities.

Operating lease costs are recognized on a straight-line basis over the lease term and included as a selling, general and administrative expense in the consolidated statements of net income and comprehensive income. Total operating lease costs were $10,309, $8,174, and $7,551 for the years ended March 31, 2020, 2019, and 2018, respectively.
