At least quarterly, the Company conducts a comprehensive security-level impairment assessment. The assessments are based on the nature of the securities, the extent and duration of the securities in an unrealized loss position, the extent and duration of the loss and management’s intent to sell or if it is more likely than not that management will be required to sell a security before recovery of its amortized cost basis, which may be maturity. Management believes the Company will fully recover the cost of these securities. It does not intend to sell these securities and likely will not be required to sell them before the anticipated recovery of the remaining amortized cost basis, which may be maturity. As a result, management concluded that these securities were not other-than-temporarily impaired at September 30, 2016.

Management reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-performing and potential problem loans. Diversification in the loan portfolio is a means of managing risk associated with fluctuations in economic conditions. Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. Underwriting standards are designed to promote relationship banking rather than transactional banking. The Company’s management examines current and occasionally projected cash flows to determine the ability of the borrower to repay their obligations as agreed. Commercial loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers; however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans, in addition to those of real estate loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be adversely affected by conditions in the real estate markets or in the general economy. The properties securing the Company’s commercial real estate portfolio are diverse in terms of type. This diversity helps reduce the Company’s exposure to adverse economic events that affect any single industry. Management monitors and evaluates commercial real estate loans based on collateral, geography and risk grade criteria. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner occupied loans. At September 30, 2016 approximately 79% of the outstanding principal balances of the Company’s commercial real estate loans were secured by owner-occupied properties as compared to 76% at December 31, 2015. With respect to loans to developers and builders that are secured by non-owner occupied properties, the Company generally requires the borrower to have had an existing relationship with the Company and have a proven record of success. Construction and land development loans are underwritten utilizing independent appraisal reviews, sensitivity analysis of absorption and lease rates and financial analysis of the developers and property owners. Construction and land development loans are generally based upon estimates of costs and value associated with the completed project. These estimates may be inaccurate. Construction and land development loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risk than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions and the availability of long-term financing. The Company originates consumer loans utilizing a judgmental underwriting process. To monitor and manage consumer loan risk, policies and procedures are developed and modified, as needed, jointly by line and staff personnel. This activity, coupled with relatively small loan amounts that are spread across many individual borrowers, minimizes risk. The Company maintains an independent loan review department that reviews and validates the credit risk program on a periodic basis. Results of these reviews are presented to management. The loan review process complements and reinforces the risk identification and assessment decisions made by lenders and credit personnel, as well as the Company’s policies and procedures. Loans serviced for others approximated $82.5 million and $76.3 million at September 30, 2016 and December 31, 2015, respectively. Concentrations of Credit Nearly all of the Company’s lending activity occurs within the state of Ohio, including the four (4) counties of Holmes, Stark, Tuscarawas and Wayne, as well as other markets. The majority of the Company’s loan portfolio consists of commercial and industrial and commercial real estate loans. As of September 30, 2016 and December 31, 2015, there were no concentrations of loans related to any single industry. Allowance for Loan Losses The following tables detail activity in the allowance for loan losses by portfolio segment for the three and nine months ended September 30, 2016 and 2015. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories. The changes in the provision for loan losses for the three and nine months ended September 30, 2016 related to commercial loans were primarily due to charge-offs of loans in this category as well as an increase in the specific reserve for one commercial relationship. The decrease in the provision related to commercial real estate loans for the nine month period in 2016 was primarily due to a recovery of a prior charge-off. The increase in the provision for consumer loans during the three and nine month periods of 2016 relates to charge-offs of loans in this category as well as the increase in loan volume. The changes in the provision for loan losses for the three and nine month periods of 2015 related to commercial and industrial loans were primarily due to the increase in a specific reserve for one commercial relationship as well as the increase in the qualitative economic factors applied to loans in this category. The decrease in the provision related to commercial real estate loans was primarily due to the overall improved credit quality of the loans in this category.

There were no new TDR’s during the three month period ended September 30, 2016. Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes commercial loans individually by classifying the loans as to credit risk. This analysis includes commercial loans with an outstanding balance greater than $300 thousand. This analysis is performed on an annual basis. The Company uses the following definitions for risk ratings: Pass Special Mention Substandard Doubtful Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans. Loans listed as not rated are either less than $300 thousand or are included in groups of homogeneous loans. Based on the most recent analysis performed, the risk category of loans by class is as follows as of September 30, 2016 and December 31, 2015: (Dollars in thousands) Pass Special Substandard Doubtful Not Rated Total September 30, 2016 Commercial $ 119,342 $ 2,570 $ 10,898 $ — $ 835 $ 133,645 Commercial real estate 148,078 2,864 6,006 — 1,048 157,996 Residential real estate 218 — 137 — 138,498 138,853 Construction & land development 13,542 744 506 — 3,827 18,619 Consumer — — — — 13,581 13,581 Total $ 281,180 $ 6,178 $ 17,547 $ — $ 157,789 $ 462,694 December 31, 2015 Commercial $ 112,229 $ 3,100 $ 7,044 $ — $ 770 $ 123,143 Commercial real estate 141,621 2,742 3,150 — 1,262 148,775 Residential real estate 190 — 213 — 125,372 125,775 Construction & land development 11,015 944 — — 3,493 15,452 Consumer — — — — 9,268 9,268 Total $ 265,055 $ 6,786 $ 10,407 $ — $ 140,165 $ 422,413 The following table presents loans that are not rated by class of loans as of September 30, 2016 and December 31, 2015.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 5 – FAIR VALUE MEASUREMENTS The Company provides disclosures about assets and liabilities carried at fair value. The framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and lowest priority to unobservable inputs. The three broad levels of the fair value hierarchy are described below: Level I: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access. Level II: Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; inputs other than quoted prices that are observable for the asset or liability; and inputs that are derived principally from or corroborated by observable market data by corroborated or other means. If the asset or liability has a specified (contractual) term, the Level II input must be observable for substantially the full term of the asset or liability. Level III: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. The following table presents the assets reported on the Consolidated Balance Sheet at their fair value as of September 30, 2016 and December 31, 2015 by level within the fair value hierarchy. No liabilities are carried at fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Equity securities and U.S. Treasury Notes are valued at the closing price reported on the active market on which the individual securities are traded. Obligations of U.S. government agencies, mortgage-backed securities, asset-backed securities, obligations of states and political subdivisions and corporate bonds are valued at observable market data for similar assets.

Impaired loans are written down to fair value through the establishment of specific reserves. Techniques used to value the collateral that secure the impaired loans include: quoted market prices for identical assets classified as Level I inputs; and observable inputs, employed by certified appraisers, for similar assets classified as Level II inputs. In cases where valuation techniques included inputs that are unobservable and are based on estimates and assumptions developed by management based on the best information available under each circumstance, the asset valuation is classified as Level III inputs.

Securities The fair value of securities available-for-sale and securities held-to-maturity which are measured on a recurring basis are determined primarily by obtaining quoted prices on nationally recognized securities exchanges or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on securities’ relationship to other similar securities, classified as Level I or Level II in the fair value hierarchy. Net loans The fair value for loans is estimated by discounting future cash flows using current market inputs at which loans with similar terms and qualities would be made to borrowers of similar credit quality. Where quoted market prices were available, primarily for certain residential mortgage loans, such market rates were utilized as estimates for fair value. Fair value of non-accrual loans is based on carrying value, classified as Level III. Bank-owned life insurance The carrying amount of bank-owned life insurance is based on the cash surrender value of the policies and is a reasonable estimate of fair value, classified as Level I. Restricted stock Restricted stock includes Federal Home Loan Bank Stock and Federal Reserve Bank Stock. It is not practicable to determine the fair value of regulatory equity securities due to restrictions placed on their transferability. Fair value is based on carrying value, classified as Level I. Mortgage servicing rights The fair value of mortgage servicing rights is based on a valuation model that calculates the present value of estimated net servicing income. The valuation model incorporates discounted cash flow and repayment assumptions based on management’s best judgment. As a result, these rights are measured at fair value on a recurring basis and are classified within Level III of the fair value hierarchy. Deposits The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rates are estimated using market rates currently offered for similar instruments with similar remaining maturities, resulting in a Level III classification. Demand, savings, and money market deposit accounts are valued at the amount payable on demand as of quarter end, resulting in a Level I classification. Other borrowings The fair value of Federal Home Loan Bank advances are estimated using a discounted cash flow analysis based on the current borrowing rates for similar types of borrowings, resulting in a Level III classification. The Company also has unrecognized financial instruments at September 30, 2016 and December 31, 2015. These financial instruments relate to commitments to extend credit and letters of credit. The aggregated contract amount of such financial instruments was approximately $157 million at September 30, 2016 and $138 million at December 31, 2015. Such amounts are also considered to be the estimated fair values. The fair value estimates of financial instruments are made at a specific point in time based on relevant market information. These estimates do not reflect any premium or discount that could result from offering for sale at one time the entire holdings of a particular financial instrument over the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Since no ready market exists for a significant portion of the financial instruments, fair value estimates are largely based on judgments after considering such factors as future expected credit losses, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore, cannot be determined with precision. Changes in assumptions could significantly affect these estimates.
