The Company’s key credit quality indicator for its investment in direct financing and sales-type leases is the status of the lease, defined as accruing or non-accrual. Leases that are accruing income are considered to have a lower risk of loss. Non-accrual leases are those that the Company believes have a higher risk of loss. The following table sets forth information regarding the Company’s accruing and non-accrual leases. Delinquent balances are determined based on the contractual terms of the lease.

The Company leases high-technology and other business-essential equipment to its leasing customers. Upon expiration of the initial term or extended lease term, depending on the structure of the lease, the customer may return the equipment, renew the lease for an additional term, or purchase the equipment. Due to the uncertainty of such outcome at the end of the lease term, the lease as recorded at commencement represents only the current terms of the agreement. As a lessor, the Company’s leases do not contain non-lease components. The residual values reflect the estimated amounts to be received at lease termination from sales or other dispositions of leased equipment to unrelated parties. The leased equipment residual values are based on the Company’s best estimate. The Company’s risk management strategy for its residual value includes the contractual obligations of customer to maintain, service, and insure the leased equipment, the use of third party remarketers as well as the analytical review of historical asset dispositions.
