1 Our residential loan portfolio does not include sub-prime loans, nor is it our practice to underwrite loans commonly referred to as "Alt-A mortgages", the characteristics of which are loans lacking full documentation, borrowers having low FICO scores or higher loan-to-value ratios. 2 One purchased credit impaired ("PCI") loan with an unpaid balance of $11 thousand and no carrying value was not accreting interest at March 31, 2018. Three PCI loans with unpaid balances totaling $131 thousand and no carrying values were not accreting interest at December 31, 2017. Amounts exclude accreting PCI loans totaling $2.1 million at both March 31, 2018 and December 31, 2017 as we have a reasonable expectation about future cash flows to be collected and we continue to recognize accretable yield on these loans in interest income. There were no accruing loans past due more than ninety days at March 31, 2018 or December 31, 2017. 3 Amounts include net deferred loan origination costs of $928 thousand and $818 thousand at March 31, 2018 and December 31, 2017, respectively. Amounts are also net of unaccreted purchase discounts on non-PCI loans of $1.1 million and $1.2 million at March 31, 2018 and December 31, 2017, respectively.
Financing Receivable Credit Quality Indicators | The following table represents an analysis of the carrying amount in loans, net of deferred fees and costs and purchase premiums or discounts, by internally assigned risk grades, including PCI loans, at March 31, 2018 and December 31, 2017.
