Notes to Financial Statements
Allowance for Credit Losses [Text Block]	Note 3 : Allowance for Loan Losses, Nonperforming Assets and Impaired Loans The allowance for loan losses methodology incorporates individual evaluation of impaired loans and collective evaluation of groups of non-impaired loans. The Company performs ongoing analysis of the loan portfolio to determine credit quality and to identify impaired loans. Credit quality is rated based on the loan’s payment history, the borrower’s current financial situation and value of the underlying collateral. Impaired Loans Loans are designated as impaired when, in the judgment of management based on current information and events, it is probable that all amounts due will not not not six may 1: Troubled debt restructurings impact the estimation of the appropriate level of the allowance for loan losses. If the restructuring included forgiveness of a portion of principal or accrued interest, the charge-off is included in the historical charge-off rates applied to the collective evaluation methodology. Restructured loans are individually evaluated for impairment, and the amount of a restructured loan’s book value in excess of its fair value is accrued as a specific allocation in the allowance for loan losses. TDRs that experience a payment default are examined to determine whether the default indicates collateral dependency or cash flows below those that were used in the fair value measurement. TDRs, as well as all impaired loans, that are determined to be collateral dependent are charged down to fair value. Deficiencies indicated by impairment measurements for TDRs that are not may Collectively-Evaluated Loans The Company evaluated characteristics in the loan portfolio and determined major segments and smaller classes within each segment. These characteristics include collateral type, repayment sources, and (if applicable) the borrower’s business model. The methodology for calculating reserves for collectively-evaluated loans is applied at the class level. Portfolio Segments and Classes The segments and classes used in determining the allowance for loan losses are as follows. Real Estate Construction Construction, residential Construction, other Consumer Real Estate Equity lines Residential closed-end first Residential closed-end junior liens Investor-owned residential real estate Commercial Real Estate Multifamily real estate Commercial real estate, owner-occupied Commercial real estate, other Commercial Non Real Estate Commercial and industrial Public Sector and IDA Public sector and IDA Consumer Non Real Estate Credit cards Automobile Other consumer loans Historical Loss Rates The Company’s allowance methodology for collectively-evaluated loans applies historical loss rates by class to current class balances as part of the process of determining required reserves. Class loss rates are calculated as the net charge-offs for the class as a percentage of average class balance. The Company averages loss rates for the most recent 8 Two loss rates for each class are calculated: total net charge-offs for the class as a percentage of average class loan balance (“class loss rate”), and total net charge-offs for the class as a percentage of average classified loans in the class (“classified loss rate”). Classified loans are those with risk ratings of “substandard” or lower. Net charge-offs in both calculations include charge-offs and recoveries of classified and non-classified loans as well as those associated with impaired loans. Class historical loss rates are applied to non-classified loan balances at the reporting date, and classified historical loss rates are applied to classified balances at the reporting date. Risk Factors In addition to historical loss rates, risk factors pertinent to credit risk for each class are analyzed to estimate reserves for collectively-evaluated loans. Factors include changes in national and local economic and business conditions, the nature and volume of classes within the portfolio, loan quality, loan officers’ experience, lending policies and the Company’s loan review system. The analysis of certain factors results in standard allocations to all segments and classes. These factors include the risk from changes in lending policies, loan officers’ average years of experience, unemployment levels, bankruptcy rates, interest rate environment, and competition/legal/regulatory environments. Factors analyzed for each class, with resultant allocations based upon the level of risk assessed for each class, include the risk from changes in loan review, levels of past due loans, levels of nonaccrual loans, current class balance as a percentage of total loans, and the percentage of high risk loans within the class. Additionally, factors specific to each segment are analyzed and result in allocations to the segment. Please refer to Note 1: Real estate construction loans are subject to general risks from changing commercial building and housing market trends and economic conditions that may The credit quality of consumer real estate is subject to risks associated with the borrower’s repayment ability and collateral value, measured generally by analyzing local unemployment and bankruptcy trends, local housing market trends, and interest rates. The commercial real estate segment includes loans secured by multifamily residential real estate, commercial real estate occupied by the owner/borrower, and commercial real estate leased to non-owners. Loans in the commercial real estate segment are impacted by economic risks from changing commercial real estate markets, rental markets for multi-family housing and commercial buildings, business bankruptcy rates, local unemployment and interest rate trends that would impact the businesses housed by the commercial real estate. Commercial non real estate loans are secured by collateral other than real estate, or are unsecured. Credit risk for commercial non real estate loans is subject to economic conditions, generally monitored by local business bankruptcy trends, and interest rates. Public sector and IDA loans are extended to municipalities and related entities. Credit risk is based upon the entity’s ability to repay and interest rate trends. Consumer non real estate includes credit cards, automobile and other consumer loans. Credit cards and certain other consumer loans are unsecured, while collateral is obtained for automobile loans and other consumer loans. Credit risk stems primarily from the borrower’s ability to repay, measured by average unemployment, average personal bankruptcy rates and interest rates. Factor allocations applied to each class are increased for loans rated special mention and increased to a greater extent for loans rated classified. The Company allocates additional reserves for “high risk” loans. High risk loans include junior liens, interest only and high loan to value loans. A detailed analysis showing the allowance roll-forward by portfolio segment and related loan balance by segment follows.

Topic 606 not not 606 not 606. 606 Service Charges on Deposit Accounts Service charges on deposit accounts consist of monthly service fees, overdraft and nonsufficient funds fees, ATM fees, wire transfer fees, and other deposit account related fees. The Company’s performance obligation for monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Wire transfer fees, overdraft and nonsufficient funds fees and other deposit account related fees are transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Other Service Charges Other service charges include safety deposit box rental fees, check ordering charges, and other service charges. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation. Check ordering charges are transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Credit and Debit Card Fees Credit and debit card fees are primarily comprised of interchange fee income and merchant services income. Interchange fees are earned whenever the Company’s debit and credit cards are processed through card payment networks such as Visa. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees. The Company’s performance obligation for interchange fee income and merchant services income are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month. In compliance with Topic 606, Trust Income Trust income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company does not Insurance and Investment Insurance income primarily consists of commissions received on insurance product sales. The Company acts as an intermediary between the Company’s customer and the insurance carrier. The Company’s performance obligation is generally satisfied upon the issuance of the insurance policy. Shortly after the insurance policy is issued, the carrier remits the commission payment to the Company, and the Company recognizes the revenue. Investment income consists of recurring revenue streams such as commissions from sales of mutual funds and other investments. Commissions from the sale of mutual funds and other investments are recognized on trade date, which is when the Company has satisfied its performance obligation. The Company also receives periodic service fees (i.e., trailers) from mutual fund companies typically based on a percentage of net asset value. Trailer revenue is recorded over time, usually monthly or quarterly, as net asset value is determined. The following presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, three March 31, 2018 2017.
