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.
