Securities	NOTE 3 SECURITIES The amortized cost and fair value of securities, with gross unrealized gains and losses at March 31, 2017 and December 31, 2016, follows: (In Thousands) March 31, 2017 Gross Gross Amortized Unrealized Unrealized Fair Cost Gains Losses Value Available-for-Sale: U.S. Treasury $ 19,872 $ — $ (137 ) $ 19,735 U.S. Government agencies 84,252 — (1,612 ) 82,640 Mortgage-backed securities 46,728 181 (866 ) 46,043 State and local governments 58,142 626 (798 ) 57,970 Total available-for-sale $ 208,994 $ 807 $ (3,413 ) $ 206,388 (In Thousands) December 31, 2016 Gross Gross Amortized Unrealized Unrealized Fair Cost Gains Losses Value Available-for-Sale: U.S. Treasury $ 24,920 $ 1 $ (146 ) $ 24,775 U.S. Government agencies 84,266 3 (1,795 ) 82,474 Mortgage-backed securities 49,155 185 (879 ) 48,461 State and local governments 63,173 634 (990 ) 62,817 Total available-for-sale $ 221,514 $ 823 $ (3,810 ) $ 218,527 Investment securities will at times depreciate to an unrealized loss position. The Company utilizes the following criteria to assess whether impairment is other than temporary. No one item by itself will necessarily signal that a security should be recognized as an other than temporary impairment. 1. The fair value of the security has significantly declined from book value. 2. A downgrade has occurred that lowered the credit rating to below investment grade (below Baa3 by Moody and BBB – by Standard and Poors.) 3. Dividends have been reduced or eliminated or scheduled interest payments have not been made. 4. The underwater security has longer than 10 years to maturity and the loss position had existed for more than 3 years. 5. Management does not possess both the intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. If the impairment is judged to be other than temporary, the cost basis of the individual security shall be written down to fair value, thereby establishing a new cost basis. The new cost basis shall not be changed for subsequent recoveries in fair value. The amount of the write down shall be included in current earnings as a realized loss. The recovery in fair value, if any, shall be recognized in earnings when the security is sold. The table below is presented by category of security and length of time in a continuous loss position. The Company currently does not hold any securities with other than temporary impairment. Information pertaining to securities with gross unrealized losses at March 31, 2017 and December 31, 2016, aggregated by investment category and length of time that individual securities have been in a continuous loss position follows: (In Thousands) March 31, 2017 Less Than Twelve Months Twelve Months & Over Gross Unrealized Fair Gross Unrealized Fair Losses Value Losses Value U.S. Treasury $ (137 ) $ 15,721 $ — $ — U.S. Government agencies (1,612 ) 82,640 — — Mortgage-backed securities (842 ) 31,224 (24 ) 3,772 State and local governments (772 ) 31,657 (26 ) 1,003 Total available-for-sale $ (3,363 ) $ 161,242 $ (50 ) $ 4,775 (In Thousands) December 31, 2016 Less Than Twelve Months Twelve Months & Over Gross Unrealized Fair Gross Unrealized Fair Losses Value Losses Value U.S. Treasury $ (146 ) $ 15,745 $ — $ — U.S. Government agencies (1,795 ) 77,471 — — Mortgage-backed securities (879 ) 36,474 — — State and local governments (983 ) 37,540 (7 ) 526 Total available-for-sale $ (3,803 ) $ 167,230 $ (7 ) $ 526 Unrealized losses on securities have not been recognized into income because the issuers’ bonds are of high credit quality, values have only been impacted by rate changes, and the Company has the intent and ability to hold the securities for the foreseeable future. Additionally, the decline in value is primarily due to changes in interest rates since the securities were purchased. The fair value is expected to recover as the bonds approach the maturity date. Below are the gross realized gains and losses as of March 31 for each of the years presented. (In Thousands) 2017 2016 Gross realized gains $ 31 $ 123 Gross realized losses — (10 ) Net realized gains $ 31 $ 113 Tax expense related to net realized gains $ 11 $ 38 The net realized gain on sales and related tax expense is a reclassification out of accumulated other comprehensive income. The net realized gain is included in net gain on sale of available-for-sale The amortized cost and fair value of debt securities at March 31, 2017, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Risks include potential construction delays and overruns, vacancies, collateral value subject to market value fluctuations, interest rate, market demands, borrower’s ability to repay in orderly fashion, and others. The Bank does employ stress testing on higher balance loans to mitigate risk by ensuring the customer’s ability to repay in a changing rate environment before granting loan approval. Agricultural Real Estate: Purchase of farm real estate or for permanent improvements to the farm real estate. Cash flow from the farm operation is the repayment source and is therefore subject to the financial success of the farm operation. Consumer Real Estate: Purchase, refinance, or equity financing of one to four family owner occupied dwelling. Success in repayment is subject to borrower’s income, debt level, character in fulfilling payment obligations, employment, and others. Commercial and Industrial: Loans to proprietorships, partnerships, or corporations to provide temporary working capital and seasonal loans as well as long term loans for capital asset acquisition. Risks include adequacy of cash flow, reasonableness of projections, financial leverage, economic trends, management ability and estimated capital expenditures during the fiscal year. The Bank does employ stress testing on higher balance loans to mitigate risk by ensuring the customer’s ability to repay in a changing rate environment before granting loan approval. Agricultural: Loans for the production and housing of crops, fruits, vegetables, and livestock or to fund the purchase or re-finance Consumer: Funding for individual and family purposes. Success in repayment is subject to borrower’s income, debt level, character in fulfilling payment obligations, employment, and others. Industrial Development Bonds (IDB): Funds for public improvements in the Bank’s service area. Repayment ability is based on the continuance of the taxation revenue as the source of repayment. The Bank uses a nine tier risk rating system to grade its loans. The grade of a loan may change during the life of the loan. The risk ratings are described as follows. 1. Zero (0) Unclassified. Any loan which has not been assigned a classification. 2. One (1) Excellent. Credit to premier customers having the highest credit rating based on an extremely strong financial condition, which compares favorably with industry standards (upper quartile of Risk Management Association ratios). Financial statements indicate a sound earnings and financial ratio trend for several years with satisfactory profit margins and excellent liquidity exhibited. Prime credits may also be borrowers with loans fully secured by highly liquid collateral such as traded stocks, bonds, certificates of deposit, savings account, etc. No credit or collateral exceptions exist and the loan adheres to the Bank’s loan policy in every respect. Financing alternatives would be readily available and would qualify for unsecured credit. This grade is summarized by high liquidity, minimum risk, strong ratios, and low handling costs. 3. Two (2) Good. Desirable loans of somewhat less stature than Grade 1, but with strong financial statements. Loan supported by financial statements containing strong balance sheets, generally with a leverage position less than 1.50, and a history of profitability. Probability of serious financial deterioration is unlikely. Possessing a sound repayment source (and a secondary source), which would allow repayment in a reasonable period of time. Individual loans backed by liquid personal assets, established history and unquestionable character. 4. Three (3) Satisfactory. Satisfactory loans of average or slightly above average risk – having some deficiency or vulnerability to changing economic conditions, but still fully collectible. Projects should normally demonstrate acceptable debt service coverage. Generally, customers should have a leverage position less than 2.00. May be some weakness but with offsetting features of other support readily available. Loans that are meeting the terms of repayment. Loans may be graded 3 when there is no recent information on which to base a current risk evaluation and the following conditions apply: At inception, the loan was properly underwritten and did not possess an unwarranted level of credit risk: a. At inception, the loan was secured with collateral possessing a loan value adequate to protect the Bank from loss; b. The loan exhibited two or more years of satisfactory repayment with a reasonable reduction of the principal balance; c. During the period that the loan has been outstanding, there has been no evidence of any credit weakness. Some examples of weakness include slow payment, lack of cooperation by the borrower, breach of loan covenants, or the business is in an industry which is known to be experiencing problems. If any of the credit weaknesses is observed, a lower risk grade is warranted. 5. Four (4) Satisfactory / Monitored. A “4” (Satisfactory/Monitored) risk grade may be established for a loan considered satisfactory but which is of average credit risk due to financial weakness or uncertainty. The loans warrant a higher than average level of monitoring to ensure that weaknesses do not advance. The level of risk in Satisfactory/Monitored classification is considered acceptable and within normal underwriting guidelines, so long as the loan is given management supervision. 6. Five (5) Special Mention. Loans that possess some credit deficiency or potential weakness which deserves close attention, but which do not yet warrant substandard classification. Such loans pose unwarranted financial risk that, if not corrected, could weaken the loan and increase risk in the future. The key distinctions of a 5 (Special Mention) classification are that (1) it is indicative of an unwarranted level of risk, and (2) weaknesses are considered “potential”, versus “defined”, impairments to the primary source of loan repayment and collateral. 7. Six (6) Substandard. One or more of the following characteristics may be exhibited in loans classified substandard: a. Loans, which possess a defined credit weakness and the likelihood that a loan will be paid from the primary source, are uncertain. Financial deterioration is underway and very close attention is warranted to ensure that the loan is collected without loss. b. Loans are inadequately protected by the current net worth and paying capacity of the borrower. c. The primary source of repayment is weakened, and the Bank is forced to rely on a secondary source of repayment such as collateral liquidation or guarantees. d. Loans are characterized by the distinct possibility that the Bank will sustain some loss if deficiencies are not corrected. e. Unusual courses of action are needed to maintain a high probability of repayment. f. The borrower is not generating enough cash flow to repay loan principal; however, continues to make interest payments. g. The lender is forced into a subordinate position or unsecured collateral position due to flaws in documentation. h. Loans have been restructured so that payment schedules, terms and collateral represent concessions to the borrower when compared to the normal loan terms. i. The lender is seriously contemplating foreclosure or legal action due to the apparent deterioration in the loan. j. There is significant deterioration in the market conditions and the borrower is highly vulnerable to these conditions. 8. Seven (7) Doubtful. One or more of the following characteristics may be exhibited in loans classified Doubtful: a. Loans have all of the weaknesses of those classified as Substandard. Additionally, however, these weaknesses make collection or liquidation in full based on existing conditions improbable. b. The primary source of repayment is gone, and there is considerable doubt as to the quality of the secondary source of repayment. c. The possibility of loss is high, but, because of certain important pending factors which may strengthen the loan, loss classification is deferred until its exact status is known. A Doubtful classification is established deferring the realization of the loss. 9. Eight (8) Loss. Loans are considered uncollectable and of such little value that continuing to carry them as assets on the institution’s financial statements is not feasible. Loans will be classified Loss when it is neither practical nor desirable to defer writing off or reserving all or a portion of a basically worthless asset, even though partial recovery may be possible at some time in the future.

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 5 EARNINGS PER SHARE Basic earnings per share are calculated using the two-class method. The two-class method is an earnings allocation formula under which earnings per share is calculated from common stock and participating securities according to dividends declared and participation rights in undistributed earnings. Under this method, all earnings distributed and undistributed, are allocated to participating securities and common shares based on their respective rights to receive dividends. Unvested share-based payment awards that contain non-forfeitable rights to dividends are considered participating securities (i.e. unvested restricted stock), not subject to performance based measures. Basic earnings per share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding.

Fair Value of Instruments

Fair Value Disclosures [Abstract]
Fair Value of Instruments	NOTE 6 FAIR VALUE OF INSTRUMENTS FAIR VALUE OF FINANCIAL INSTRUMENTS Fair values of financial instruments are management’s estimate of the values at which the instruments could be exchanged in a transaction between willing parties. These estimates are subjective and may vary significantly from amounts that would be realized in actual transactions. In addition, other significant assets are not considered financial assets including deferred tax assets, premises, equipment and intangibles. Further, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on the fair value estimates and have not been considered in any of the estimates. The following assumptions and methods were used in estimating the fair value for financial instruments: Cash and Cash Equivalents The carrying amounts reported in the balance sheet for cash, cash equivalents and federal funds sold approximate their fair values. Also included in this line item are the carrying amounts of interest-bearing deposits maturing within ninety days which approximate their fair values. Fair values of other interest-bearing deposits are estimated using discounted cash flow analyses based on current rates for similar types of deposits. Interest Bearing Time Deposits Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow analysis that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. Securities – Available-for-sale Fair values for securities, excluding Federal Home Loan Bank and Farmer Mac stock, are based on quoted market price, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. Other Securities The carrying value of Federal Home Loan Bank and Farmer Mac stock, listed as “other securities”, approximates fair value based on the redemption provisions of the Federal Home Loan Bank. Loans Held for Sale The carrying amount approximates fair value due to insignificant amount of time between origination and date of sale. Loans, net For those variable-rate loans that re-price Deposits The fair values disclosed for deposits with no defined maturities are equal to their carrying amounts, which represent the amount payable on demand. The carrying amounts for variable-rate, fixed term money market accounts and certificates of deposit approximate their fair value at the reporting date. Fair value for fixed-rate certificates of deposit are estimated using a discounted cash flow analysis that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. Federal Funds Purchased and Securities Sold Under Agreements to Repurchase The carrying value of federal funds purchased and securities sold under agreements to repurchase approximates fair values. Accrued Interest Receivable and Payable The carrying amounts of accrued interest approximate their fair values. Off Balance Sheet Financial Instruments Fair values for off-balance FHLB Advances Fair values or FHLB advances are estimated using discounted cash flow analysis based on the Company’s current incremental borrowing rates for similar types or borrowing arrangements.

Available-for-sale Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly. These Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals. Available-for-sale Level 3 inputs are unobservable inputs, including inputs that are available in situations where there is little, if any, market activity for the related asset or liability. The Bank holds some local municipals that the Bank evaluates based on the credit strength of the underlying project. The fair value is determined by valuing similar credit payment streams at similar rates. In instances where inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Company’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset. The following summarizes financial assets measured at fair value on a recurring basis as of March 31, 2017 and December 31, 2016, segregated by level or the valuation inputs within the fair value hierarchy utilized to measure fair value: Assets and Liabilities Measured at Fair Value on a Recurring Basis (In Thousands) Quoted Prices in Significant Significant Active Markets Observable Observable for Identical Inputs Inputs March 31, 2017 Assets (Level 1) (Level 2) (Level 3) Assets - (Securities Available-for-Sale) U.S. Treasury $ 19,735 $ — $ — U.S. Government agencies — 82,640 — Mortgage-backed securities — 46,043 — State and local governments — 56,556 1,414 Total Securities Available-for-Sale $ 19,735 $ 185,239 $ 1,414 Quoted Prices in Significant Significant Active Markets Observable Observable for Identical Inputs Inputs December 31, 2016 Assets (Level 1) (Level 2) (Level 3) Assets - (Securities Available-for-Sale) U.S. Treasury $ 24,775 $ — $ — U.S. Government agencies — 82,474 — Mortgage-backed securities — 48,461 — State and local governments — 61,399 1,418 Total Securities Available-for-Sale $ 24,775 $ 192,334 $ 1,418 The following table represents the changes in the Level 3 fair-value category of which unobservable inputs are relied upon as of March 31, 2017 and March 31, 2016.

The specific allocation for impaired loans was $117 and $135 thousand as of March 31, 2017 and December 31, 2016, respectively, which are accounted for in the allowance for loan losses (see Note 4). Other real estate is reported at either the lower of the fair value of the real estate minus the estimated costs to sell the asset or the cost of the asset. The determination of fair value of the real estate relies primarily on appraisals from third parties. If the fair value of the real estate, minus the estimated costs to sell the asset, is less than the asset’s cost, the deficiency is recognized as a valuation allowance against the asset through a charge to expense. The valuation allowance is therefore increased or decreased, through charges or credits to expense, for changes in the asset’s fair value or estimated selling costs.
