Credit Quality Of Commercial Loan Portfolio

The following table provides information about the credit quality of the Commercial loan portfolio, using the Company’s internal rating system as an indicator. The internal rating system is a series of grades reflecting management’s risk assessment, based on its analysis of the borrower’s financial condition. The “pass” category consists of a range of loan grades that reflect increasing, though still acceptable, risk. Movement of risk through the various grade levels in the “pass” category is monitored for early identification of credit deterioration. The “special mention” rating is attached to loans where the borrower exhibits material negative financial trends due to borrower specific or systemic conditions that, if left uncorrected, threaten its capacity to meet its debt obligations. The borrower is believed to have sufficient financial flexibility to react to and resolve its negative financial situation. It is a transitional grade that is closely monitored for improvement or deterioration. The “substandard” rating is applied to loans where the borrower exhibits well-defined weaknesses that jeopardize its continued performance and are of a severity that the distinct possibility of default exists. Loans are placed on “non-accrual” when management does not expect to collect payments consistent with acceptable and agreed upon terms of repayment, as discussed in Note 1.

Summary Of Loans In The Personal Banking Portfolio Percentage Of Balances Outstanding

The credit quality of Personal Banking loans is monitored primarily on the basis of aging/delinquency, and this information is provided in the table in the above section on "Delinquent and non-accrual loans". In addition, FICO scores are obtained and updated on a quarterly basis for most of the loans in the Personal Banking portfolio. This is a published credit score designed to measure the risk of default by taking into account various factors from a person's financial history. The bank normally obtains a FICO score at the loan's origination and renewal dates, and updates are obtained on a quarterly basis. Excluded from the table below are certain personal real estate loans for which FICO scores are not obtained because the loans are related to commercial activity. These loans totaled $219.2 million at December 31, 2017 and $237.2 million at December 31, 2016. The table also excludes consumer loans related to the Company's patient healthcare loan program, which totaled $145.0 million at December 31, 2017 and $75.4 million at December 31, 2016. As the healthcare loans are guaranteed by the hospital, FICO scores are not considered relevant for this program. The personal real estate loans and consumer loans excluded below totaled less than 7% of the Personal Banking portfolio. For the remainder of loans in the Personal Banking portfolio, the table below shows the percentage of balances outstanding at December 31, 2017 and 2016 by FICO score.

Additional Information about Troubled Debt Restructurings [Table Text Block]

Troubled debt restructurings also include certain credit card loans under various debt management and assistance programs. Modifications to credit card loans generally involve removing the available line of credit, placing loans on amortizing status, and lowering the contractual interest rate. The Company also classified certain loans as troubled debt restructurings because they were not reaffirmed by the borrower in bankruptcy proceedings. These loans are comprised of personal real estate, revolving home equity and consumer loans. Interest on these loans is being recognized on an accrual basis, as the borrowers are continuing to make payments.

The table below summarizes the troubled debt restructurings outstanding by type of modification, as described above.
