We have operating leases primarily related to branch facilities, data centers, sales offices, and agent locations, automobiles and office equipment. Many of our leases include both lease (fixed rent payments) and non-lease components (common-area or other maintenance costs) which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases. Variable lease payments, such as periodically indexed and/or market adjustments, are presented as lease expense in the period in which they are incurred. Since we did not elect the short-term policy election, we record leases of 12 months or less on the balance sheet.

We exclude options to extend or terminate a lease from our recognition as part of our right-of-use assets and lease liabilities until those options are reasonably certain and/or executed. We do not have any material guarantees, options to purchase, or restrictive covenants related to our leases.

As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. We consider qualitative factors including our derived credit rating, notched adjustments for collateralization, lease term, and, if significant, adjustments to our collateralized rate to borrow in the same currency in which the lease is denominated.
