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 Amounts include $1 thousand of Purchased Credit Impaired ("PCI") loans that had stopped accreting interest at December 31, 2015. Amounts exclude accreting PCI loans of $2.8 million and $3.7 million at March 31, 2016 and December 31, 2015, respectively, 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. These accreting PCI loans are included in current loans. 3 Amounts include net deferred loan costs of $693 thousand and $768 thousand at March 31, 2016 and December 31, 2015, respectively. Amounts are also net of unaccreted purchase discounts on non-PCI loans of $2.8 million and $3.2 million at March 31, 2016 and December 31, 2015, respectively.
