PART I

Forward-Looking Statements

This report contains forward-looking statements with respect to the financial condition, results of operations and business of American National Bankshares Inc. (the "Company") and its wholly owned subsidiary, American National Bank and Trust Company (the "Bank"). These forward-looking statements involve risks and uncertainties and are based on the beliefs and assumptions of management of the Company and on information available to management at the time these statements and disclosures were prepared. Forward-looking statements are subject to numerous assumptions, estimates, risks, and uncertainties that could cause actual conditions, events, or results to differ materially from those stated or implied by such forward-looking statements.

A variety of factors, some of which are discussed in more detail in Item 1A – Risk Factors, may affect the operations, performance, business strategy, and results of the Company. Those factors include but are not limited to the following:

• financial market volatility including the level of interest rates could affect the values of financial instruments and the amount of net interest income earned;

• general economic or business conditions, either nationally or in the market areas in which the Company does business, may be less favorable than expected, resulting in deteriorating credit quality, reduced demand for credit, or a weakened ability to generate deposits;

• competition among financial institutions may increase and competitors may have greater financial resources and develop products and technology that enable those competitors to compete more successfully than the Company;

• businesses that the Company is engaged in may be adversely affected by legislative or regulatory changes, including changes in accounting standards and tax laws;

• the ability to retain key personnel;

• the failure of assumptions underlying the allowance for loan losses; and

• risks associated with mergers, acquisitions, and other expansion activities.

ITEM 1 – BUSINESS

American National Bankshares Inc. is a one-bank holding company organized under the laws of the Commonwealth of Virginia in 1984.  On September 1, 1984, the Company acquired all of the outstanding capital stock of American National Bank and Trust Company, a national banking association chartered in 1909 under the laws of the United States.  American National Bank and Trust Company is the only banking subsidiary of the Company.

On January 1, 2015, the Company completed its acquisition of MainStreet BankShares, Inc. ("MainStreet") pursuant to the terms and conditions of the Agreement and Plan of Reorganization, dated as of August 24, 2014, between the Company and MainStreet.  Immediately after the merger of MainStreet into the Company, Franklin Community Bank, N.A. ("Franklin Bank"), MainStreet's wholly-owned bank subsidiary, merged with and into the Bank. Franklin Bank provided banking services to its customers from three banking offices located in Rocky Mount, Hardy, and Union Hall, Virginia.

As of December 31, 2017, the operations of the Company are conducted at twenty-six banking offices and two loan production offices in Roanoke, Virginia and Raleigh, North Carolina.  Through these offices, the Company serves its primary market area of south central Virginia and north central North Carolina. The Bank provides a full array of financial products and services, including commercial, mortgage, and consumer banking; trust and investment services; and insurance.  Services are also provided through thirty-four Automated Teller Machines ("ATMs"), "Online Banking," and "Telephone Banking."

The Company has two reportable segments, (i) community banking and (ii) trust and investment services. For more financial data and other information about each of the Company’s operating segments, refer to "Note 20 - Segment and Related Information" of the Consolidated Financial Statements contained in Item 8 of this Form 10-K.

Competition and Markets

Vigorous competition exists in the Company's service areas.  The Company competes not only with national, regional, and community banks, but also with other types of financial institutions including savings banks, finance companies, mutual and money market fund providers, brokerage firms, insurance companies, credit unions, and mortgage companies.

The Company’s primary market area is south central Virginia and north central North Carolina. The Company also has a significant presence in Roanoke, Virginia. The Company's Virginia banking offices are located in the cities of Danville, Lynchburg and Martinsville and in the counties of Bedford, Campbell, Franklin, Halifax, Henry, Pittsylvania and Roanoke.  In North Carolina, the Company's banking offices are located in the cities of Burlington, Graham, Greensboro, Mebane and Winston-Salem and in the counties of Alamance, Caswell and Guilford. 

4

The Company has the largest deposit market share in the City of Danville, Virginia.  The Company had a deposit market share in the Danville Micropolitan Statistical Area of 35.3% at June 30, 2017, based on Federal Deposit Insurance Corporation ("FDIC") data. The Company has the second largest deposit market share in Pittsylvania County, Virginia.  The Company had a deposit market share in Pittsylvania County of 23.4% at June 30, 2017, based on FDIC data.

The Virginia market area, in which the Company has a significant presence, continues to show improvement. The region's economic base continues to be weighted toward the manufacturing sector.  Although the region was negatively impacted by the elimination of many textile plant closings over several decades, the area has experienced some new manufacturing plant openings as well as job growth in the technology area. Other important industries include farming, tobacco processing and sales, food processing, and packaging tape production.

The Company's market area in North Carolina has strong competition in attracting deposits and making loans. Its most direct competition for deposits comes from commercial banks, savings institutions and credit unions located in the market area, including large financial institutions that have greater financial and marketing resources available to them.  The Company had a deposit market share in Alamance County of 15.0% at June 30, 2017, based on FDIC data, which was the second largest of any FDIC-insured institution.

In the fall of 2016, the Company announced the opening of a de novo branch in each of Roanoke, Virginia and Winston-Salem, North Carolina.

Supervision and Regulation

The Company and the Bank are extensively regulated under federal and state law.  The following information describes certain aspects of that regulation applicable to the Company and the Bank and does not purport to be complete.  Proposals to change the laws, regulations, and policies governing the banking industry are frequently raised in U.S. Congress, in state legislatures, and before the various bank regulatory agencies.  The likelihood and timing of any changes and the impact such changes might have on the Company and the Bank are impossible to determine with any certainty.  A change in applicable laws, regulations or policies, or a change in the way such laws, regulations or policies are interpreted by regulatory agencies or courts, may have a material impact on the business, operations, and earnings of the Company and the Bank.

American National Bankshares Inc.

American National Bankshares Inc. is qualified as a bank holding company ("BHC") within the meaning of the Bank Holding Company Act of 1956, as amended (the "BHC Act"), and is registered as such with the Board of Governors of the Federal Reserve System (the "FRB").  As a bank holding company, American National Bankshares Inc. is subject to supervision, regulation and examination by the FRB and is required to file various reports and additional information with the FRB.  American National Bankshares Inc. is also registered under the bank holding company laws of Virginia and is subject to supervision, regulation and examination by the Bureau of Financial Institutions of the Virginia State Corporation Commission (the "SCC").

Under the Gramm-Leach-Bliley Act, a BHC may elect to become a financial holding company and thereby engage in a broader range of financial and other activities than are permissible for traditional BHC's.  In order to qualify for the election, all of the depository institution subsidiaries of the BHC must be well capitalized, well managed, and have achieved a rating of "satisfactory" or better under the Community Reinvestment Act (the "CRA").  Financial holding companies are permitted to engage in activities that are "financial in nature" or incidental or complementary thereto as determined by the FRB.  The Gramm-Leach-Bliley Act identifies several activities as "financial in nature," including insurance underwriting and sales, investment advisory services, merchant banking and underwriting, and dealing or making a market in securities.  American National Bankshares Inc. has not elected to become a financial holding company, and has no plans to become a financial holding company.

American National Bank and Trust Company

American National Bank and Trust Company is a federally chartered national bank and is a member of the Federal Reserve System.  As a national bank, the Bank is subject to supervision, regulation and examination by the Office of the Comptroller of the Currency (the "OCC") and is required to file various reports and additional information with the OCC.  The OCC has primary supervisory and regulatory authority over the operations of the Bank. Because the Bank accepts insured deposits from the public, it is also subject to examination by the FDIC.

Depository institutions, including the Bank, are subject to extensive federal and state regulations that significantly affect their business and activities. Regulatory bodies have broad authority to implement standards and initiate proceedings designed to prohibit depository institutions from engaging in unsafe and unsound banking practices.  The standards relate generally to

5

operations and management, asset quality, interest rate exposure, and capital.  The bank regulatory agencies are authorized to take action against institutions that fail to meet such standards.

As with other financial institutions, the earnings of the Bank are affected by general economic conditions and by the monetary policies of the FRB. The FRB exerts a substantial influence on interest rates and credit conditions, primarily through open market operations in U.S. Government securities, setting the reserve requirements of member banks, and establishing the discount rate on member bank borrowings. The policies of the FRB have a direct impact on loan and deposit growth and the interest rates charged and paid thereon. They also impact the source, cost of funds, and the rates of return on investments. Changes in the FRB's monetary policies have had a significant impact on the operating results of the Bank and other financial institutions and are expected to continue to do so in the future; however, the exact impact of such conditions and policies upon the future business and earnings cannot accurately be predicted.

The Dodd-Frank Act

On July 21, 2010, President Obama signed into law the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"). The Dodd-Frank Act significantly restructured the financial regulatory regime in the United States and has had a broad impact on the financial services industry as a result of the significant regulatory and compliance changes required under the act. A summary of certain provisions of the Dodd-Frank Act is set forth below:

Increased Capital Standards.  The federal banking agencies are required to establish minimum leverage and risk-based capital requirements for banks and bank holding companies. See "Capital Requirements" below. Among other things, the Dodd-Frank Act provides for newer and stronger standards.

Deposit Insurance.  The Dodd-Frank Act makes permanent the $250,000 deposit insurance limit for insured deposits. Amendments to the Federal Deposit Insurance Act also revise the assessment base against which an insured depository institution's deposit insurance premiums paid to the Deposit Insurance Fund (the "DIF") will be calculated. Under the amendments, the assessment base will no longer be the institution's deposit base, but rather its average consolidated total assets less its average tangible equity during the assessment period.  Additionally, the Dodd-Frank Act makes changes to the minimum designated reserve ratio of the DIF, increasing the minimum from 1.15% to 1.35% of the estimated amount of total insured deposits and eliminating the requirement that the FDIC pay dividends to depository institutions when the reserve ratio exceeds certain thresholds. The Dodd-Frank Act also provides that depository institutions may pay interest on demand deposits.

The Consumer Financial Protection Bureau ("CFPB").  The CFPB is charged with establishing rules and regulations under certain federal consumer protection laws with respect to the conduct of providers of certain consumer financial products and services.

Compensation Practices.  The Dodd-Frank Act provides that the appropriate federal regulators must establish standards prohibiting as an unsafe and unsound practice any compensation plan of a bank holding company or bank that provides an insider or other employee with "excessive compensation" or could lead to a material financial loss to such firm. In June 2010, prior to the Dodd-Frank Act, the federal bank regulatory agencies promulgated the Interagency Guidance on Sound Incentive Compensation Policies, which requires that financial institutions establish metrics for measuring the impact of activities to achieve incentive compensation with the related risk to the financial institution of such behavior.

In 2017, Congress introduced legislation that would repeal or modify provisions of the Dodd-Frank Act and significantly impact financial services regulation. Although the bills vary in content, certain key aspects include revisions to rules related to mortgage loans, delayed implementation of rules related to the Home Mortgage Disclosure Act and raising the threshold for applying enhanced prudential standards to bank holding companies with total consolidated assets equal to or greater than $50 billion to those with total consolidated assets equal to or greater than $250 billion.

The Dodd-Frank Act has had, and may in the future have, a material impact on the Company’s operations, particularly through increased compliance costs resulting from new and possible future consumer and fair lending regulations. The future changes resulting from the Dodd-Frank Act may affect the profitability of business activities, require changes to certain business practices, impose more stringent regulatory requirements or otherwise adversely affect the business and financial condition of the Company and the Bank. These changes may also require the Company to invest significant management attention and resources to evaluate and make necessary changes to comply with new statutory and regulatory requirements.

Deposit Insurance

The deposits of the Bank are insured up to applicable limits by the Deposit Insurance Fund of the FDIC and are subject to deposit insurance assessments to maintain the DIF. On April 1, 2011, the deposit insurance assessment base changed from total deposits to average total assets minus average tangible equity, pursuant to a rule issued by the FDIC as required by the Dodd-

6

Frank Act. Also on April 1, 2011, the FDIC began utilizing a risk-based assessment system that imposed insurance premiums based upon a risk category matrix that took into account a bank’s capital level and supervisory rating. Effective July 1, 2016, the FDIC again changed its deposit insurance pricing and eliminated all risk categories and now uses the "financial ratios method" based on CAMELS composite ratings to determine assessment rates for small established institutions with less than $10 billion in assets. The CAMELS rating system is a supervisory rating system designed to take into account and reflect all financial and operational risks that a bank may face, including capital adequacy, asset quality, management capability, earnings, liquidity and sensitivity to market risk ("CAMELS"). CAMELS composite ratings set a maximum assessment for CAMELS 1 and 2 rated banks, and set minimum assessments for lower rated institutions.

The FDIC’s "reserve ratio" of the DIF to total industry deposits reached its 1.15% target effective June 30, 2016. On March 15, 2016, the FDIC implemented by final rule certain Dodd-Frank Act provisions by raising the DIF’s minimum reserve ratio from 1.15% to 1.35%. The FDIC imposed a 4.5 basis point annual surcharge on insured depository institutions with total consolidated assets of $10 billion or more. The new rule grants credits to smaller banks for the portion of their regular assessments that contribute to increasing the reserve ratio from 1.15% to 1.35%. Prior to when the new assessment system became effective, the Bank’s overall rate for assessment calculations was 9 basis points or less, which was within the range of assessment rates for the lowest risk category under the former FDIC assessment rules. In 2017 and 2016, the Company recorded expense of $538,000 and $647,000, respectively, for FDIC insurance premiums.

In addition, all FDIC insured institutions are required to pay assessments to the FDIC at an annual rate of approximately one basis point of insured deposits to fund interest payments on bonds issued by the Financing Corporation, an agency of the federal government established to recapitalize the predecessor to the Savings Association Insurance Fund. These assessments will continue until the Financing Corporation bonds mature in 2019.

Capital Requirements

The FRB, the OCC and the FDIC have issued substantially similar risk-based and leverage capital guidelines applicable to all banks and bank holding companies.  In addition, those regulatory agencies may from time to time require that a banking organization maintain capital above the minimum levels because of its financial condition or actual or anticipated growth. Under the risk-based capital requirements of these federal bank regulatory agencies that were effective through December 31, 2017, the Company and the Bank were required to maintain a minimum ratio of total capital (which is defined as core capital and supplementary capital less certain specified deductions from total capital such as reciprocal holdings of depository institution capital instruments and equity investments) to risk-weighted assets of at least 8.0%.  In determining the amount of risk-weighted assets, all assets, including certain off-balance sheet activities, recourse obligations, residual interests and direct credit substitutes, were multiplied by a risk-weight factor assigned by the capital regulation based on the risks believed inherent in the type of asset. 

On June 7, 2012, the FRB issued a series of proposed rules intended to revise and strengthen its risk-based and leverage capital requirements and its method for calculating risk-weighted assets. The rules were proposed to implement the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision (the "Basel Committee") and certain provisions of the Dodd-Frank Act.  On July 2, 2013, the FRB and the OCC approved certain revisions to the proposals and finalized new capital requirements for banking organizations.

Effective January 1, 2015, the final rules required the Company and the Bank to comply with the following new minimum capital ratios: (i) a new common equity Tier 1 capital ratio of 4.5% of risk-weighted assets; (ii) a Tier 1 capital ratio of 6% of risk-weighted assets (increased from the prior requirement of 4%); (iii) a total capital ratio of 8% of risk-weighted assets (unchanged from the prior requirement); and (iv) a leverage ratio of 4% of total assets (unchanged from the prior requirement).  These are the initial capital requirements, which will be phased-in over a four-year period.  When fully phased-in on January 1, 2019, the rules will require the Company and the  Bank to maintain (i) a minimum ratio of common equity Tier 1 to risk-weighted assets of at least 4.5%, plus a 2.5% "capital conservation buffer" (which is added to the 4.5% common equity Tier 1 ratio as that buffer is phased-in, effectively resulting in a minimum ratio of common equity Tier 1 to risk-weighted assets of at least 7% upon full implementation), (ii) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the 2.5% capital conservation buffer (which is added to the 6.0% Tier 1 capital ratio as that buffer is phased-in, effectively resulting in a minimum Tier 1 capital ratio of 8.5% upon full implementation), (iii) a minimum ratio of total capital to risk-weighted assets of at least 8.0%, plus the 2.5% capital conservation buffer (which is added to the 8.0% total capital ratio as that buffer is phased-in, effectively resulting in a minimum total capital ratio of 10.5% upon full implementation), and (iv) a minimum leverage ratio of 4%, calculated as the ratio of Tier 1 capital to average assets.

The Tier 1 and total capital to risk-weighted asset ratios of the Company were 13.42% and 14.39%, respectively, as of December 31, 2017, thus exceeding the minimum requirements. The common equity Tier 1 capital ratio of the Company was

7

11.50% and the Bank was 12.79% as of December 31, 2017. The Tier 1 and total capital to risk-weighted asset ratios of the Bank were 12.79% and 13.75%, respectively, as of December 31, 2017 also exceeding the minimum requirements.

The phase-in of the capital conservation buffer requirement began on January 1, 2016, at 0.625% of risk-weighted assets, increasing by the same amount each year until fully implemented at 2.5% on January 1, 2019. The capital conservation buffer is designed to absorb losses during periods of economic stress.  Banking institutions with a ratio of common equity Tier 1 to risk-weighted assets above the minimum but below the conservation buffer will face constraints on dividends, equity repurchases, and compensation based on the amount of the shortfall.

With respect to the Bank, the rules also revised the "prompt corrective action" regulations pursuant to Section 38 of the FDIA by (i) introducing a common equity Tier 1 capital ratio requirement at each level (other than critically undercapitalized), with the required ratio being 6.5% for well-capitalized status; (ii) increasing the minimum Tier 1 capital ratio requirement for each category, with the minimum ratio for well-capitalized status being 8.0% (as compared to the prior ratio of 6.0%); and (iii) eliminating the current provision that provides that a bank with a composite supervisory rating of 1 may have a 3.0% Tier 1 leverage ratio and still be well-capitalized.  These new thresholds were effective for the Bank as of January 1, 2015.  The minimum total capital to risk-weighted assets ratio (10.0%) and minimum leverage ratio (5.0%) for well-capitalized status were unchanged by the final rules.

The new capital requirements also included changes in the risk weights of assets to better reflect credit risk and other risk exposures. These include a 150% risk weight (up from 100%) for certain high volatility commercial real estate acquisition, development and construction loans and nonresidential mortgage loans that are 90 days past due or otherwise on nonaccrual status, a 20% (up from 0%) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancelable, a 250% risk weight (up from 100%) for mortgage servicing rights and deferred tax assets that are not deducted from capital, and increased risk-weights (from 0% to up to 600%) for equity exposures.

In September 2017, the federal bank regulatory agencies proposed to revise and simplify the capital treatment for certain deferred tax assets, mortgage servicing assets, investments in non-consolidated financial entities and minority interests for banking organizations, such as the Bank, that are not subject to the advanced approaches requirements. In November 2017, the regulatory agencies revised the capital rules enacted in 2013 to extend the current transitional treatment of these items for non-advanced approaches banking organizations until the September 2017 proposal is finalized. The September 2017 proposal would also change the capital treatment of certain commercial real estate loans under the standardized approach, which the Bank uses to calculate its capital ratios.

In December 2017, the Basel Committee published standards that it described as the finalization of the Basel III post-crisis regulatory reforms (the standards are commonly referred to as “Basel IV”). Among other things, these standards revise the Basel Committee’s standardized approach for credit risk (including by recalibrating risk weights and introducing new capital requirements for certain “unconditionally cancellable commitments,” such as unused credit card lines of credit) and provide a new standardized approach for operational risk capital. Under the proposed framework, these standards will generally be effective on January 1, 2022, with an aggregate output floor phasing-in through January 1, 2027. Under the current capital rules, operational risk capital requirements and a capital floor apply only to advanced approaches institutions, and not to the Company. The impact of Basel IV on the Company and the Bank will depend on the manner in which it is implemented by the federal bank regulatory agencies.

Based on management's understanding and interpretation of the capital rules, it believes that, as of December 31, 2017, the Company and the Bank meet all capital adequacy requirements under such rules on a fully phased-in basis as if such requirements were in effect as of such date.

Dividends

The Company's principal source of cash flow, including cash flow to pay dividends to its shareholders, is dividends it receives from the Bank.  Statutory and regulatory limitations apply to the Bank's payment of dividends to the Company. As a general rule, the amount of a dividend may not exceed, without prior regulatory approval, the sum of net income in the calendar year to date and the retained net earnings of the immediately preceding two calendar years. A depository institution may not pay any dividend if payment would cause the institution to become "undercapitalized" or if it already is "undercapitalized." The OCC may prevent the payment of a dividend if it determines that the payment would be an unsafe and unsound banking practice. The OCC also has advised that a national bank should generally pay dividends only out of current operating earnings.

Permitted Activities

As a bank holding company, American National Bankshares Inc. is limited to managing or controlling banks, furnishing services to or performing services for its subsidiaries, and engaging in other activities that the FRB determines by regulation or order to be so closely related to banking or managing or controlling banks as to be a proper incident thereto. In determining whether a particular activity is permissible, the FRB must consider whether the performance of such an activity reasonably can be expected to produce benefits to the public that outweigh possible adverse effects. Possible benefits include greater convenience, increased competition, and gains in efficiency. Possible adverse effects include undue concentration of resources, decreased or unfair competition, conflicts of interest, and unsound banking practices. Despite prior approval, the FRB may order a bank holding company or its subsidiaries to terminate any activity or to terminate ownership or control of any subsidiary when the FRB has reasonable cause to believe that a serious risk to the financial safety, soundness or stability of any bank subsidiary of that bank holding company may result from such an activity.

Banking Acquisitions; Changes in Control

The BHC Act requires, among other things, the prior approval of the FRB in any case where a bank holding company proposes to (i) acquire direct or indirect ownership or control of more than 5% of the outstanding voting stock of any bank or bank holding company (unless it already owns a majority of such voting shares), (ii) acquire all or substantially all of the assets of another bank or bank holding company, or (iii) merge or consolidate with any other bank holding company. In determining whether to approve a proposed bank acquisition, the FRB will consider, among other factors, the effect of the acquisition on competition, the public benefits expected to be received from the acquisition, the projected capital ratios and levels on a post-acquisition basis, and the acquiring institution's performance under the Community Reinvestment Act of 1977 (the "CRA") and its compliance with fair housing and other consumer protection laws.

Subject to certain exceptions, the BHC Act and the Change in Bank Control Act, together with the applicable regulations, require FRB approval (or, depending on the circumstances, no notice of disapproval) prior to any person or company acquiring "control" of a bank or bank holding company. A conclusive presumption of control exists if an individual or company acquires the power, directly or indirectly, to direct the management or policies of an insured depository institution or to vote 25% or more of any class of voting securities of any insured depository institution. A rebuttable presumption of control exists if a person or company acquires 10% or more but less than 25% of any class of voting securities of an insured depository institution and either the institution has registered its securities with the Securities and Exchange Commission under Section 12 of the Securities Exchange Act of 1934 (the "Exchange Act") or no other person will own a greater percentage of that class of voting securities immediately after the acquisition. The Company's common stock is registered under Section 12 of the Exchange Act.

In addition, Virginia law requires the prior approval of the SCC for (i) the acquisition of more than 5% of the voting shares of a Virginia bank or any holding company that controls a Virginia bank, or (ii) the acquisition by a Virginia bank holding company of a bank or its holding company domiciled outside Virginia.

Source of Strength

FRB policy has historically required bank holding companies to act as a source of financial and managerial strength to their subsidiary banks. The Dodd-Frank Act codified this policy as a statutory requirement. Under this requirement, the Company is expected to commit resources to support the Bank, including at times when the Company may not be in a financial position to provide such resources. Any capital loans by a bank holding company to any of its subsidiary banks are subordinate in right of payment to depositors and to certain other indebtedness of such subsidiary banks. In the event of a bank holding company's bankruptcy, any commitment by the bank holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank will be assumed by the bankruptcy trustee and entitled to priority of payment.

Safety and Soundness

There are a number of obligations and restrictions imposed on bank holding companies and their subsidiary banks by law and regulatory policy that are designed to minimize potential loss to the depositors of such depository institutions and the FDIC insurance fund in the event of a depository institution default. For example, under the Federal Deposit Insurance Corporation Improvement Act of 1991, to avoid receivership of an insured depository institution subsidiary, a bank holding company is required to guarantee the compliance of any subsidiary bank that may become "undercapitalized" with the terms of any capital restoration plan filed by such subsidiary with its appropriate federal bank regulatory agency up to the lesser of (i) an amount equal to 5% of the institution's total assets at the time the institution became undercapitalized or (ii) the amount that is necessary (or would have been necessary) to bring the institution into compliance with all applicable capital standards as of the time the institution fails to comply with such capital restoration plan.

9

Under the FDIA, the federal bank regulatory agencies have adopted guidelines prescribing safety and soundness standards. These guidelines establish general standards relating to internal controls and information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth and compensation, fees and benefits. In general, the guidelines require, among other things, appropriate systems and practices to identify and manage the risk and exposures specified in the guidelines.

The Federal Deposit Insurance Corporation Improvement Act

Under the Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA"), the federal bank regulatory agencies possess broad powers to take prompt corrective action to resolve problems of insured depository institutions.  The extent of these powers depends upon whether the institution is "well capitalized," "adequately capitalized," "undercapitalized," "significantly undercapitalized," or "critically undercapitalized," as defined by the law. 

Reflecting changes under the new Basel III capital requirements, the relevant capital measures that became effective on January 1, 2015 for prompt corrective action are the total capital ratio, the common equity Tier 1 capital ratio, the Tier 1 capital ratio and the leverage ratio.  A bank will be (i) "well capitalized" if the institution has a total risk-based capital ratio of 10.0% or greater, a common equity Tier 1 capital ratio of 6.5% or greater, a Tier 1 risk-based capital ratio of 8.0% or greater, and a leverage ratio of 5.0% or greater, and is not subject to any capital directive order; (ii) "adequately capitalized" if the institution has a total risk-based capital ratio of 8.0% or greater, a common equity Tier 1 capital ratio of 4.5% or greater, a Tier 1 risk-based capital ratio of 6.0% or greater, and a leverage ratio of 4.0% or greater and is not "well capitalized"; (iii) "undercapitalized" if the institution has a total risk-based capital ratio that is less than 8.0%, a common equity Tier 1 capital ratio less than 4.5%, a Tier 1 risk-based capital ratio of less than 6.0% or a leverage ratio of less than 4.0%; (iv) "significantly undercapitalized" if the institution has a total risk-based capital ratio of less than 6.0%, a common equity Tier 1 capital ratio less than 3.0%, a Tier 1 risk-based capital ratio of less than 4.0% or a leverage ratio of less than 3.0%; and (v) "critically undercapitalized" if the institution's tangible equity is equal to or less than 2.0% of average quarterly tangible assets. An institution may be downgraded to, or deemed to be in, a capital category that is lower than indicated by its capital ratios if it is determined to be in an unsafe or unsound condition or if it receives an unsatisfactory examination rating with respect to certain matters. A bank's capital category is determined solely for the purpose of applying prompt corrective action regulations, and the capital category may not constitute an accurate representation of the bank's overall financial condition or prospects for other purposes.  Management believes, as of December 31, 2017 and 2016, the Company met the requirements for being classified as "well capitalized."

As required by FDICIA, the federal bank regulatory agencies also have adopted guidelines prescribing safety and soundness standards relating to, among other things, internal controls and information systems, internal audit systems, loan documentation, credit underwriting, and interest rate exposure.  In general, the guidelines require appropriate systems and practices to identify and manage the risks and exposures specified in the guidelines.  In addition, the agencies adopted regulations that authorize, but do not require, an institution which has been notified that it is not in compliance with safety and soundness standard to submit a compliance plan.  If, after being so notified, an institution fails to submit an acceptable compliance plan, the agency must issue an order directing action to correct the deficiency and may issue an order directing other actions of the types to which an undercapitalized institution is subject under the prompt corrective action provisions described above.

Branching

Pursuant to the Dodd-Frank Act, national and state-chartered banks may open an initial branch in a state other than its home state (e.g., a host state) by establishing a de novo branch at any location in such host state at which a bank chartered in such host state could establish a branch. Applications to establish such branches must still be filed with the appropriate primary federal bank regulatory agency and state bank regulatory authorities may require applications or notices.

Transactions with Affiliates

Pursuant to Sections 23A and 23B of the Federal Reserve Act and Regulation W, the authority of the Bank to engage in transactions with related parties or "affiliates" or to make loans to insiders is limited. Loan transactions with an affiliate generally must be collateralized and certain transactions between the Bank and its affiliates, including the sale of assets, the payment of money or the provision of services, must be on terms and conditions that are substantially the same, or at least as favorable to the Bank, as those prevailing for comparable nonaffiliated transactions. In addition, the Bank generally may not purchase securities issued or underwritten by affiliates.

Loans to executive officers, directors or to any person who directly or indirectly, or acting through or in concert with one or more persons, owns, controls or has the power to vote more than 10% of any class of voting securities of a bank (a "10% Shareholders"), are subject to Sections 22(g) and 22(h) of the Federal Reserve Act and their corresponding regulations

10

(Regulation O) and Section 13(k) of the Exchange Act relating to the prohibition on personal loans to executives (which exempts financial institutions in compliance with the insider lending restrictions of Section 22(h) of the Federal Reserve Act). Among other things, these loans must be made on terms substantially the same as those prevailing on transactions made to unaffiliated individuals and certain extensions of credit to those persons must first be approved in advance by a disinterested majority of the entire board of directors. Section 22(h) of the Federal Reserve Act prohibits loans to any of those individuals where the aggregate amount exceeds an amount equal to 15% of an institution's unimpaired capital and surplus plus an additional 10% of unimpaired capital and surplus in the case of loans that are fully secured by readily marketable collateral, or when the aggregate amount on all of the extensions of credit outstanding to all of these persons would exceed the Bank's unimpaired capital and unimpaired surplus. Section 22(g) of the Federal Reserve Act identifies limited circumstances in which the Bank is permitted to extend credit to executive officers.

Consumer Financial Protection

The Company is subject to a number of federal and state consumer protection laws that extensively govern its relationship with its customers. These laws include the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Truth in Lending Act, the Truth in Savings Act, the Electronic Fund Transfer Act, the Expedited Funds Availability Act, the Home Mortgage Disclosure Act, the Fair Housing Act, the Real Estate Settlement Procedures Act, the Fair Debt Collection Practices Act, the Service Members Civil Relief Act, laws governing flood insurance, federal and state laws prohibiting unfair and deceptive business practices, foreclosure laws ,and various regulations that implement some or all of the foregoing. These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must deal with customers when taking deposits, making loans, collecting loans and providing other services. If the Company fails to comply with these laws and regulations, it may be subject to various penalties. Failure to comply with consumer protection requirements may also result in failure to obtain any required bank regulatory approval for merger or acquisition transactions the Company may wish to pursue or being prohibited from engaging in such transactions even if approval is not required.

The Dodd-Frank Act centralized responsibility for consumer financial protection by creating a new agency, the CFPB, and giving it responsibility for implementing, examining, and enforcing compliance with federal consumer protection laws. The CFPB focuses on (i) risks to consumers and compliance with the federal consumer financial laws, (ii) the markets in which firms operate and risks to consumers posed by activities in those markets, (iii) depository institutions that offer a wide variety of consumer financial products and services, and (iv) non-depository companies that offer one or more consumer financial products or services. The CFPB has broad rule making authority for a wide range of consumer financial laws that apply to all banks, including, among other things, the authority to prohibit "unfair, deceptive or abusive" acts and practices. Abusive acts or practices are defined as those that materially interfere with a consumer's ability to understand a term or condition of a consumer financial product or service or take unreasonable advantage of a consumer's (i) lack of financial savvy, (ii) inability to protect himself in the selection or use of consumer financial products or services, or (iii) reasonable reliance on a covered entity to act in the consumer's interests. The CFPB can issue cease-and-desist orders against banks and other entities that violate consumer financial laws. The CFPB may also institute a civil action against an entity in violation of federal consumer financial law in order to impose a civil penalty or injunction.

Community Reinvestment Act

The CRA requires the appropriate federal banking agency, in connection with its examination of a bank, to assess the bank's record in meeting the credit needs of the communities served by the bank, including low and moderate income neighborhoods.  Furthermore, such assessment is also required of banks that have applied, among other things, to merge or consolidate with or acquire the assets or assume the liabilities of an insured depository institution, or to open or relocate a branch.  In the case of a BHC applying for approval to acquire a bank or BHC, the record of each subsidiary bank of the applicant BHC is subject to assessment in considering the application.  Under the CRA, institutions are assigned a rating of "outstanding," "satisfactory," "needs to improve," or "substantial non-compliance."  The Company was rated "satisfactory" in its most recent CRA evaluation.

Anti-Money Laundering Legislation

The Company is subject to the Bank Secrecy Act and other anti-money laundering laws and regulations, including the USA Patriot Act of 2001.  Among other things, these laws and regulations require the Company to take steps to prevent the use of the Company for facilitating the flow of illegal or illicit money, to report large currency transactions, and to file suspicious activity reports.  The Company is also required to carry out a comprehensive anti-money laundering compliance program.  Violations can result in substantial civil and criminal sanctions.  In addition, provisions of the USA Patriot Act require the federal bank regulatory agencies to consider the effectiveness of a financial institution's anti-money laundering activities when reviewing bank mergers and BHC acquisitions.

11

Office of Foreign Assets Control

The U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) is responsible for administering and enforcing economic and trade sanctions against specified foreign parties, including countries and regimes, foreign individuals and other foreign organizations and entities. OFAC publishes lists of prohibited parties that are regularly consulted by the Company in the conduct of its business in order to assure compliance. The Company is responsible for, among other things, blocking accounts of, and transactions with, prohibited parties identified by OFAC, avoiding unlicensed trade and financial transactions with such parties and reporting blocked transactions after their occurrence. Failure to comply with OFAC requirements could have serious legal, financial and reputational consequences for the Company.

Privacy Legislation

Several recent laws, including the Right to Financial Privacy Act, and related regulations issued by the federal bank regulatory agencies, also provide new protections against the transfer and use of customer information by financial institutions. A financial institution must provide to its customers information regarding its policies and procedures with respect to the handling of customers' personal information. Each institution must conduct an internal risk assessment of its ability to protect customer information. These privacy provisions generally prohibit a financial institution from providing a customer's personal financial information to unaffiliated parties without prior notice and approval from the customer.

Incentive Compensation

In June 2010, the federal bank regulatory agencies issued comprehensive final guidance on incentive compensation policies intended to ensure that the incentive compensation policies of financial institutions do not undermine the safety and soundness of such institutions by encouraging excessive risk-taking. The Interagency Guidance on Sound Incentive Compensation Policies, which covers all employees that have the ability to materially affect the risk profile of a financial institutions, either individually or as part of a group, is based upon the key principles that a financial institution's incentive compensation arrangements should (i) provide incentives that do not encourage risk-taking beyond the institution's ability to effectively identify and manage risks, (ii) be compatible with effective internal controls and risk management, and (iii) be supported by strong corporate governance, including active and effective oversight by the financial institution's board of directors.

Section 956 of the Dodd-Frank Act requires the federal banking agencies and the Securities and Exchange Commission to establish joint regulations or guidelines prohibiting incentive-based payment arrangements at specified regulated entities that encourage inappropriate risk-taking by providing an executive officer, employee, director or principal shareholder with excessive compensation, fees, or benefits or that could lead to material financial loss to the entity. The federal banking agencies issued such proposed rules in March 2011 and issued a revised proposed rule in June 2016 implementing the requirements and prohibitions set forth in Section 956. The revised proposed rule would apply to all banks, among other institutions, with at least $1 billion in average total consolidated assets, like the Bank, for which it would go beyond the existing Interagency Guidance on Sound Incentive Compensation Policies to (i) prohibit certain types and features of incentive-based compensation arrangements for senior executive officers, (ii) require incentive-based compensation arrangements to adhere to certain basic principles to avoid a presumption of encouraging inappropriate risk, (iii) require appropriate board or committee oversight and (iv) establish minimum recordkeeping and (v) mandate disclosures to the appropriate federal banking agency.

The FRB will review, as part of the regular, risk-focused examination process, the incentive compensation arrangements of financial institutions, such as the Company, that are not "large, complex banking organizations." These reviews will be tailored to each financial institution based on the scope and complexity of the institution's activities and the prevalence of incentive compensation arrangements. The findings of the supervisory initiatives will be included in reports of examination. Deficiencies will be incorporated into the institution's supervisory ratings, which can affect the institution's ability to make acquisitions and take other actions. Enforcement actions may be taken against a financial institution if its incentive compensation arrangements, or related risk-management control or governance processes, pose a risk to the institution's safety and soundness and the financial institution is not taking prompt and effective measures to correct the deficiencies. At December 31, 2017, the Company had not been made aware of any instances of non-compliance with the final guidance.

Ability-to-Repay and Qualified Mortgage Rule

Pursuant to the Dodd-Frank Act, the CFPB issued a final rule on January 10, 2013 (effective on January 10, 2014), amending Regulation Z as implemented by the Truth in Lending Act, requiring mortgage lenders to make a reasonable and good faith determination based on verified and documented information that a consumer applying for a mortgage loan has a reasonable ability to repay the loan according to its terms. Mortgage lenders are required to determine consumers' ability to repay in one of two ways. The first alternative requires the mortgage lender to consider the following eight underwriting factors when making the credit decision: (i) current or reasonably expected income or assets; (ii) current employment status; (iii) the

12

monthly payment on the covered transaction; (iv) the monthly payment on any simultaneous loan; (v) the monthly payment for mortgage-related obligations; (vi) current debt obligations, alimony, and child support; (vii) the monthly debt-to-income ratio or residual income; and (viii) credit history. Alternatively, the mortgage lender can originate "qualified mortgages," which are entitled to a presumption that the creditor making the loan satisfied the ability-to-repay requirements. In general, a "qualified mortgage" is a mortgage loan without negative amortization, interest-only payments, balloon payments, or terms exceeding 30 years. In addition, to be a qualified mortgage the points and fees paid by a consumer cannot exceed 3% of the total loan amount. Qualified mortgages that are "higher-priced" (e.g. subprime loans) garner a rebuttable presumption of compliance with the ability-to-repay rules, while qualified mortgages that are not "higher-priced" (e.g. prime loans) are given a safe harbor of compliance. The Company is predominantly an originator of compliant qualified mortgages.

Cybersecurity

In March 2015, federal regulators issued two related statements regarding cybersecurity. One statement indicates that financial institutions should design multiple layers of security controls to establish lines of defense and to ensure that their risk management processes also address the risk posed by compromised customer credentials, including security measures to reliably authenticate customers accessing internet-based services of the financial institution. The other statement indicates that a financial institution’s management is expected to maintain sufficient business continuity planning processes to ensure the rapid recovery, resumption and maintenance of the institution’s operations after a cyber-attack involving destructive malware. A financial institution is also expected to develop appropriate processes to enable recovery of data and business operations and address rebuilding network capabilities and restoring data if the institution or its critical service providers fall victim to this type of cyber-attack. If the Company fails to observe the regulatory guidance, it could be subject to various regulatory sanctions, including financial penalties.

Future Legislation and Regulation

Congress may enact legislation from time to time that affects the regulation of the financial services industry, and state legislatures may enact legislation from time to time affecting the regulation of financial institutions chartered by or operating in those states. Federal and state regulatory agencies also periodically propose and adopt changes to their regulations or change the manner in which existing regulations are applied. The substance or impact of pending or future legislation or regulation, or the application thereof, cannot be predicted, although enactment of the proposed legislation could impact the regulatory structure under which the Company and the Bank operate and may significantly increase costs, impede the efficiency of internal business processes, require an increase in regulatory capital, require modifications to business strategy, and limit the ability to pursue business opportunities in an efficient manner. A change in statutes, regulations or regulatory policies applicable to the Company or the Bank could have a material adverse effect on the business, financial condition and results of operations of the Company and the Bank.

Effect of Governmental Monetary Policies

The Company's operations are affected not only by general economic conditions, but also by the policies of various regulatory authorities.  In particular, the FRB regulates money and credit conditions and interest rates to influence general economic conditions.  These policies have a significant impact on overall growth and distribution of loans, investments and deposits; they affect interest rates charged on loans or paid for time and savings deposits.  FRB monetary policies have had a significant effect on the operating results of commercial banks, including the Company, in the past and are expected to do so in the future.  As a result, it is difficult for the Company to predict the potential effects of possible changes in monetary policies upon its future operating results.

Tax Reform

On December 22, 2017, the President of the United States signed into law the Tax Cut and Jobs Act of 2017 (the “Tax Reform Act”). The legislation made key changes to the U.S. tax law, including the reduction of the U.S. federal corporate tax rate from 35% to 21%, effective January 1, 2018. As a result of the reduction in the U.S. corporate income tax rate from 35% to 21% under the Tax Reform Act, the Company revalued its ending net deferred tax assets at December 31, 2017 and recognized a provisional $2.7 million tax expense in the Company’s consolidated statement of income for the year ended December 31, 2017. The Company is still analyzing certain aspects of the new law and refining its calculations, which could affect the measurement of these assets and liabilities or give rise to new deferred tax amounts. The accounting is expected to be complete when the 2017 U.S. corporate income tax return is filed in 2018.

Employees

At December 31, 2017, the Company employed 328 full-time equivalent persons.  In the opinion of the management of the Company, the relationship with employees of the Company and the Bank is good.

ITEM 1A – RISK FACTORS

Risks Related to the Company's Business

The Company's business is subject to interest rate risk, and variations in interest rates and inadequate management of interest rate risk may negatively affect financial performance.

Changes in the interest rate environment may reduce the Company's profits.  It is expected that the Company will continue to realize income from the spread between the interest earned on loans, securities, and other interest earning assets, and interest paid on deposits, borrowings and other interest bearing liabilities.  Net interest spreads are affected by the difference between the maturities and repricing characteristics of interest earning assets and interest bearing liabilities.  In addition, loan volume and yields are affected by market interest rates on loans, and the current interest rate environment encourages extreme competition for new loan originations from qualified borrowers.  Management cannot ensure that it can minimize the Company's interest rate risk. While an increase in the general level of interest rates may increase the loan yield and the net interest margin, it may adversely affect the ability of certain borrowers with variable rate loans to pay the interest and principal of their obligations.  In addition, rising interest rates may result in the Company’s interest expense increasing, with a commensurate adverse effect on net interest income, particularly if the Company must pay interest on demand deposits to attract or retain customer accounts. As interest rates increase, deposit costs will continue to increase, which could adversely impact the Company’s net interest income. In a rising rate environment, competition for cost-effective deposits can be expected to increase, making it more costly for the Company to fund loan growth. Accordingly, changes in levels of market interest rates could materially and adversely affect the net interest spread, asset quality, loan origination volume, and overall profitability of the Company.

14

The Company faces strong competition from financial services companies and other companies that offer banking and other financial services, which could negatively affect the Company's business.

The Company encounters substantial competition from other financial institutions in its market area.  Ultimately, the Company may not be able to compete successfully against current and future competitors. Many competitors offer the same banking services that the Company offers.  These competitors include national, regional, and community banks.  The Company also faces competition from many other types of financial institutions, including savings banks, finance companies, mutual and money market fund providers, brokerage firms, insurance companies, credit unions, financial subsidiaries of certain industrial corporations, and mortgage companies.  In particular, competitors include several major financial companies whose greater resources may afford them a marketplace advantage by enabling them to maintain numerous banking locations and ATMs and conduct extensive promotional and advertising campaigns. Increased competition may result in reduced business for the Company.

Additionally, banks and other financial institutions with larger capitalization and financial intermediaries not subject to bank regulatory restrictions have larger lending limits and are thereby able to serve the credit needs of larger customers. These institutions also may have differing pricing and underwriting standards, which may adversely affect the Company through the loss of business or causing a misalignment in the Company’s risk-return relationship. Areas of competition include interest rates for loans and deposits, efforts to obtain loans and deposits, and range and quality of products and services provided, including new technology-driven products and services.  Technological innovation continues to contribute to greater competition in domestic financial services markets as technological advances enable more companies to provide financial services.  If the Company is unable to attract and retain banking customers, it may be unable to continue to grow loan and deposit portfolios and its results of operations and financial condition may be adversely affected.

Changes in economic conditions could materially and negatively affect the Company's business.

The Company's business is directly impacted by economic, political, and market conditions, broad trends in industry and finance, legislative and regulatory changes, changes in government monetary and fiscal policies, and inflation, all of which are beyond the Company's control.  A deterioration in economic conditions, whether caused by global, national or local events, especially within the Company's market area, could result in potentially negative material consequences such as the following, among others: loan delinquencies increasing; problem assets and foreclosures increasing; demand for products and services decreasing; low cost or noninterest bearing deposits decreasing; and collateral for loans, especially real estate, declining in value, in turn reducing customers' borrowing power, and reducing the value of assets and collateral associated with existing loans.  Each of these consequences may have a material adverse effect on the Company's financial condition and results of operations.

Trust division income is a major source of non-interest income for the Company.  Trust and Brokerage fee revenue is largely dependent on the fair market value of assets under management and on trading volumes in the brokerage business. General economic conditions and their subsequent effect on the securities markets tend to act in correlation.  When general economic conditions deteriorate, securities markets generally decline in value, and the Company's Trust and Brokerage fee revenue are negatively impacted as asset values and trading volumes decrease.

The Company's credit standards and its on-going credit assessment processes might not protect it from significant credit losses.

The Company takes credit risk by virtue of making loans and extending loan commitments and letters of credit.  The Company manages credit risk through a program of underwriting standards, the review of certain credit decisions and an on-going process of assessment of the quality of the credit already extended.  The Company's exposure to credit risk is managed through the use of consistent underwriting standards that emphasize local lending while avoiding highly leveraged transactions as well as excessive industry and other concentrations.  The Company's credit administration function employs risk management techniques to help ensure that problem loans are promptly identified.  While these procedures are designed to provide the Company with the information needed to implement policy adjustments where necessary and to take appropriate corrective actions, and have proven to be reasonably effective to date, there can be no assurance that such measures will be effective in avoiding future undue credit risk.

The Company's focus on lending to small to mid-sized community-based businesses may increase its credit risk.

Most of the Company's commercial business and commercial real estate loans are made to small business or middle market customers.  These businesses generally have fewer financial resources in terms of capital or borrowing capacity than larger entities and have a heightened vulnerability to economic conditions.  Additionally, these loans may increase concentration risk as to industry or collateral securing the loans. If general economic conditions in the market areas in which the Company operates negatively impact this important customer sector, the Company's results of operations and financial condition may be

15

adversely affected.  Moreover, a portion of these loans have been made by the Company in recent years and the borrowers may not have experienced a complete business or economic cycle.  The deterioration of the borrowers' businesses may hinder their ability to repay their loans with the Company, which could have a material adverse effect on the Company's financial condition and results of operations.

The Company depends on the accuracy and completeness of information about clients and counterparties, and its financial condition could be adversely affected if it relies on misleading information.

In deciding whether to extend credit or to enter into other transactions with clients and counterparties, the Company may rely on information furnished to it by or on behalf of clients and counterparties, including financial statements and other financial information, which the Company does not independently verify.  The Company also may rely on representations of clients and counterparties as to the accuracy and completeness of that information and, with respect to financial statements, on reports of independent auditors.  For example, in deciding whether to extend credit to clients, the Company may assume that a customer's audited financial statements conform with accounting principles generally accepted in the United States ("GAAP") and present fairly, in all material respects, the financial condition, results of operations and cash flows of the customer.  The Company's financial condition and results of operations could be negatively impacted to the extent it relies on financial statements that do not comply with GAAP or are materially misleading.

The allowance for loan losses may not be adequate to cover actual losses.

In accordance with accounting principles generally accepted in the United States, an allowance for loan losses is maintained to provide for loan losses.  The allowance for loan losses may not be adequate to cover actual credit losses, and future provisions for credit losses could materially and adversely affect operating results.  The allowance for loan losses is based on prior experience, as well as an evaluation of the risks in the current portfolio.  The amount of future losses is susceptible to changes in economic, operating, and other outside forces and conditions, including changes in interest rates, all of which are beyond the Company's control; and these losses may exceed current estimates.  Federal bank regulatory agencies, as a part of their examination process, review the Company's loans and allowance for loan losses.  While management believes that the allowance for loan losses is adequate to cover current losses, it cannot make assurances that it will not further increase the allowance for loan losses or that regulators will not require it to increase this allowance.  Either of these occurrences could adversely affect earnings.

Nonperforming assets take significant time to resolve and adversely affect the Company's results of operations and financial condition.

The Company's nonperforming assets adversely affect its net income in various ways.  The Company does not record interest income on nonaccrual loans, which adversely affects its income and increases credit administration costs.  When the Company receives collateral through foreclosures and similar proceedings, it is required to mark the related asset to the then fair market value of the collateral less estimated selling costs, which may, and often does, result in a loss.  An increase in the level of nonperforming assets also increases the Company's risk profile and may impact the capital levels regulators believe are appropriate in light of such risks.  The Company utilizes various techniques such as workouts, restructurings and loan sales to manage problem assets.  Increases in or negative adjustments in the value of these problem assets, the underlying collateral, or in the borrowers' performance or financial condition, could adversely affect the Company's business, results of operations and financial condition.  In addition, the resolution of nonperforming assets requires significant commitments of time from management and staff, which can be detrimental to the performance of their other responsibilities, including generation of new loans.  There can be no assurance that the Company will avoid increases in nonperforming loans in the future.

A downturn in the local real estate market could materially and negatively affect the Company's business.

The Company offers a variety of secured loans, including commercial lines of credit, commercial term loans, real estate, construction, home equity lines of credit, consumer and other loans. Many of these loans are secured by real estate (both residential and commercial) located in the Company's market area. A downturn in the real estate market in the areas in which the Company conducts its operations could negatively affect the Company's business because significant portions of its loans are secured by real estate.  At December 31, 2017, the Company had approximately $1.3 billion in loans, of which approximately $1.1 billion (80.8%) were secured by real estate.  The ability to recover on defaulted loans by selling the real estate collateral could then be diminished and the Company would be more likely to suffer losses.

Substantially all of the Company's real property collateral is located in its market area.  If there is a decline in real estate values, especially in the Company's market area, the collateral for loans would deteriorate and provide significantly less security.

16

The Company relies upon independent appraisals to determine the value of the real estate which secures a significant portion of its loans, and the values indicated by such appraisals may not be realizable if the Company is forced to foreclose upon such loans.

A significant portion of the Company's loan portfolio consists of loans secured by real estate. The Company relies upon independent appraisers to estimate the value of such real estate.  Appraisals are only estimates of value and the independent appraisers may make mistakes of fact or judgment which adversely affect the reliability of their appraisals. In addition, events occurring after the initial appraisal may cause the value of the real estate to increase or decrease.  As a result of any of these factors, the real estate securing some of the Company's loans may be more or less valuable than anticipated at the time the loans were made.  If a default occurs on a loan secured by real estate that is less valuable than originally estimated, the Company may not be able to recover the outstanding balance of the loan and will suffer a loss.

The Company is dependent on key personnel and the loss of one or more of those key personnel may materially and adversely affect the Company's operations and prospects.

The Company is a relationship-driven organization. A key aspect of the Company’s business strategy is for its senior officers to have primary contact with current and potential customers. The Company’s growth and development is in large part a result of these personalized relationships with the customer base. The success of the Company also often depends on its ability to hire and retain qualified banking officers.

The Company’s senior officers have considerable experience in the banking industry and related financial services and are extremely valuable and would be difficult to replace. The loss of the services of these officers could have a material adverse effect upon future prospects. Although the Company has entered into employment contracts with certain of its senior executive officers, and purchased key man life insurance policies to mitigate the risk of an unforeseen departure or death of certain of the senior executive officers, it cannot offer any assurance that they and other key employees will remain employed by the Company. The unexpected loss of services of one or more of these key employees could have a material adverse effect on operations and possibly result in reduced revenues.

The inability of the Company to successfully manage its growth or implement its growth strategy may adversely affect the Company's results of operations and financial condition.

The Company may not be able to successfully implement its growth strategy if it is unable to identify attractive markets, locations or opportunities to expand in the future.  In addition, the ability to manage growth successfully depends on whether the Company can maintain adequate capital levels, cost controls and asset quality, and successfully integrate any businesses acquired into the Company.

As the Company continues to implement its growth strategy by opening new branches or acquiring branches or banks, it expects to incur increased personnel, occupancy and other operating expenses.  In the case of new branches, the Company must absorb those higher expenses while it begins to generate new deposits; there is also further time lag involved in redeploying new deposits into attractively priced loans and other higher yielding earning assets.  The Company's plans to expand could depress earnings in the short run, even if it efficiently executes a branching strategy leading to long-term financial benefits.

Difficulties in combining the operations of acquired entities with the Company's own operations may prevent the Company from achieving the expected benefits from acquisitions.

The Company may not be able to achieve fully the strategic objectives and operating efficiencies expected in an acquisition.  Inherent uncertainties exist in integrating the operations of an acquired entity.  In addition, the markets and industries in which the Company and its potential acquisition targets operate are highly competitive.  The Company may lose customers or the customers of acquired entities as a result of an acquisition; the Company may lose key personnel, either from the acquired entity or from itself; and the Company may not be able to control the incremental increase in noninterest expense arising from an acquisition in a manner that improves its overall operating efficiencies.  These factors could contribute to the Company's not achieving the expected benefits from its acquisitions within desired time frames, if at all.  Future business acquisitions could be material to the Company and it may issue additional shares of common stock to pay for those acquisitions, which would dilute current shareholders' ownership interests.  Acquisitions also could require the Company to use substantial cash or other liquid assets or to incur debt; the Company could therefore become more susceptible to economic downturns and competitive pressures.

The Company is subject to extensive regulation which could adversely affect its business.

The Company's operations as a publicly traded corporation, a bank holding company, and an insured depository institution are subject to extensive regulation by federal, state, and local governmental authorities and are subject to various laws and

17

judicial and administrative decisions imposing requirements and restrictions on part or all of the Company's operations.  Because the Company's business is highly regulated, the laws, rules, and regulations applicable to it are subject to frequent and sometimes extensive change. Such changes could include higher capital requirements, increased insurance premiums, increased compliance costs, reductions of non-interest income and limitations on services that can be provided.  Actions by regulatory agencies or significant litigation against the Company could cause it to devote significant time and resources to defend itself and may lead to liability or penalties that materially affect the Company and its shareholders. Any future changes in the laws, rules or regulations applicable to the Company may negatively affect the Company's business and results of operations.

Recently enacted capital standards may have an adverse effect on the Company's profitability, lending, and ability to pay dividends on the Company's securities.

In July 2013, the FRB and the OCC released final rules which implement the Basel III regulatory capital reforms from the Basel Committee and certain changes required by the Dodd-Frank Act. Under the final rules, minimum requirements for both the quality and quantity of capital held by banking organizations have increased. Consistent with the international Basel framework, the rule includes a new minimum ratio of common equity Tier 1 capital to risk-weighted assets of 4.5% and a common equity Tier 1 capital conservation buffer of 2.5% of risk-weighted assets that applies to all supervised financial institutions. The rule also, among other things, raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4% to 6% and included a minimum leverage ratio of 4% for all banking organizations. The new rules became effective January 1, 2015. The potential impact of the new capital rules includes, but is not limited to, reduced lending and negative pressure on profitability and return on equity due to the higher capital requirements. To the extent the Company is required to increase capital in the future to comply with the new capital rules, its ability to pay dividends on its securities may be reduced.

In December 2017, the Basel Committee published standards that it described as the finalization of the Basel III post-crisis regulatory reforms (the standards are commonly referred to as “Basel IV”). Among other things, these standards revise the Basel Committee’s standardized approach for credit risk (including by recalibrating risk weights and introducing new capital requirements for certain “unconditionally cancellable commitments,” such as unused credit card lines of credit) and provide a new standardized approach for operational risk capital. Under the proposed framework, these standards will generally be effective on January 1, 2022, with an aggregate output floor phasing-in through January 1, 2027. Under the current capital rules, operational risk capital requirements and a capital floor apply only to advanced approaches institutions, and not to the Company. The impact of Basel IV on the Company and the Bank will depend on the manner in which it is implemented by the federal bank regulatory agencies.

New regulations issued by the Consumer Financial Protection Bureau could adversely the Company's earnings.

The CFPB has broad rule making authority to administer and carry out the provisions of the Dodd-Frank Act with respect to financial institutions that offer covered financial products and services to consumers. Pursuant to the Dodd-Frank Act, the CFPB issued a final rule effective January 10, 2014, requiring mortgage lenders to make a reasonable and good faith determination based on verified and documented information that a consumer applying for a mortgage loan has a reasonable ability to repay the loan according to its terms, or to originate "qualified mortgages" that meet specific requirements with respect to terms, pricing and fees. The new rule also contains new disclosure requirements at mortgage loan origination and in monthly statements. These requirements could limit the Company's ability to make certain types of loans or loans to certain borrowers, or could make it more expensive and/or time consuming to make these loans, which could adversely impact the Company's profitability.

Changes in accounting standards could impact reported earnings.

From time to time, with increasing frequency, there are changes in the financial accounting and reporting standards that govern the preparation of the Company's financial statements.  These changes can materially impact how the Company records and reports its financial condition and results of operations.  In some instances, the Company could be required to apply a new or revised standard retroactively, resulting in the restatement of prior period financial statements.

Failure to maintain effective systems of internal and disclosure control could have a material adverse effect on the Company's results of operation and financial condition.

Effective internal and disclosure controls are necessary for the Company to provide reliable financial reports and effectively prevent fraud and to operate successfully as a public company.  If the Company cannot provide reliable financial reports or prevent fraud, its reputation and operating results would be harmed.  As part of the Company's ongoing monitoring of internal control, it may discover material weaknesses or significant deficiencies in its internal control that require remediation.  A "material weakness" is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company's annual or interim financial statements will not be prevented or detected on a timely basis.

18

The Company has in the past discovered, and may in the future discover, areas of its internal controls that need improvement.  Even so, the Company is continuing to work to improve its internal controls.  The Company cannot be certain that these measures will ensure that it implements and maintains adequate controls over its financial processes and reporting in the future.  Any failure to maintain effective controls or to timely effect any necessary improvement of the Company's internal and disclosure controls could, among other things, result in losses from fraud or error, harm the Company's reputation or cause investors to lose confidence in the Company's reported financial information, all of which could have a material adverse effect on the Company's results of operation and financial condition.

The carrying value of goodwill may be adversely impacted.

When the Company completes an acquisition, generally goodwill is recorded on the date of acquisition as an asset.  Current accounting guidance requires for goodwill to be tested for impairment, which the Company performs an impairment analysis at least annually, rather than amortizing it over a period of time.  A significant adverse change in expected future cash flows or sustained adverse change in the Company's common stock could require the asset to become impaired.  If impaired, the Company would incur a non-cash charge to earnings that would have a significant impact on the results of operations.  The carrying value of goodwill was approximately $43.9 million at December 31, 2017.

The Company may need to raise additional capital in the future to continue to grow, but may be unable to obtain additional capital on favorable terms or at all.

Federal and state banking regulators and safe and sound banking practices require the Company to maintain adequate levels of capital to support its operations.  Although the Company currently has no specific plans for additional offices, its business strategy calls for it to continue to grow in its existing banking markets (internally and through additional offices) and to expand into new markets as appropriate opportunities arise. Continued growth in the Company's earning assets, which may result from internal expansion and new branch offices, at rates in excess of the rate at which its capital is increased through retained earnings, will reduce the Company's capital ratios. If the Company's capital ratios fell below "well capitalized" levels, the FDIC deposit insurance assessment rate would increase until capital was restored and maintained at a "well capitalized" level. A higher assessment rate would cause an increase in the assessments the Company pays for federal deposit insurance, which would have an adverse effect on the Company's operating results.

Management of the Company believes that its current and projected capital position is sufficient to maintain capital ratios significantly in excess of regulatory requirements for the next several years and allow the Company flexibility in the timing of any possible future efforts to raise additional capital.   However, if, in the future, the Company needs to increase its capital to fund additional growth or satisfy regulatory requirements, its ability to raise that additional capital will depend on conditions at that time in the capital markets, economic conditions, the Company's financial performance and condition, and other factors, many of which are outside its control.  There is no assurance that the Company will be able to raise additional capital on terms favorable to it or at all.  Any future inability to raise additional capital on terms acceptable to the Company may have a material adverse effect on its ability to expand operations, and on its financial condition, results of operations and future prospects.

The Company relies on other companies to provide key components of the Company's business infrastructure.

Third parties provide key components of the Company's business operations such as data processing, recording and monitoring transactions, online banking interfaces and services, Internet connections and network access.  While the Company has selected these third party vendors carefully, it does not control their actions.  Any problem caused by these third parties, including those resulting from disruptions in communication services provided by a vendor, failure of a vendor to handle current or higher volumes, cybersecurity breaches, failure of a vendor to provide services for any reason or poor performance of services, could adversely affect the Company's ability to deliver products and services to its customers and otherwise conduct its business.  Financial or operational difficulties of a third party vendor could also hurt the Company's operations if those difficulties interface with the vendor's ability to serve the Company.  Replacing these third party vendors could also create significant delay and expense.  Accordingly, use of such third parties creates an unavoidable inherent risk to the Company's business operations.

The Company's exposure to operational, technological and organizational risk may adversely affect the Company.

The Company is exposed to many types of operational risks, including reputation, legal, and compliance risk, the risk of fraud or theft by employees or outsiders, unauthorized transactions by employees or operational errors, clerical or record-keeping errors, and errors resulting from faulty or disabled computer or telecommunications systems.

Negative public opinion can result from the actual or alleged conduct in any number of activities, including lending practices, corporate governance, and acquisitions, and from actions taken by government regulators and community

19

organizations in response to those activities.  Negative public opinion can adversely affect the Company's ability to attract and retain customers and can expose it to litigation and regulatory action.

Certain errors may be repeated or compounded before they are discovered and successfully rectified. The Company's necessary dependence upon automated systems to record and process its transactions may further increase the risk that technical system flaws or employee tampering or manipulation of those systems will result in losses that are difficult to detect.  The Company may also be subject to disruptions of its operating systems arising from events that are wholly or partially beyond its control (for example, computer viruses or electrical or telecommunications outages), which may give rise to disruption of service to customers and to financial loss or liability. The Company is further exposed to the risk that its external vendors may be unable to fulfill their contractual obligations (or will be subject to the same risk of fraud or operational errors by their respective employees as is the Company) and to the risk that the Company's (or its vendors') business continuity and data security systems prove to be inadequate.

The Company's operations may be adversely affected by cybersecurity risks.

The Company relies heavily on communications and information systems to conduct business.  Any failure, interruption, or breach in security of these systems could result in failures or disruptions in the Company's internet banking, deposit, loan, and other systems.  While the Company has policies and procedures designed to prevent or limit the effect of such failure, interruption, or security breach of the Company's information systems, there can be no assurance that they will not occur or, if they do occur, that they will be adequately addressed.  Further, to access the Company’s products and services, its customers may use computers and mobile devices that are beyond the Company’s security control systems. The occurrence of any failure, interruption or security breach of the Company's communications and information systems could damage the Company's reputation, result in a loss of customer business, subject the Company to additional regulatory scrutiny, or expose the Company to civil litigation and possible financial liability.  Additionally, the Company outsources its data processing to a third party. If the Company's third party provider encounters difficulties or if the Company has difficulty in communicating with such third party, it will significantly affect the Company's ability to adequately process and account for customer transactions, which would significantly affect its business operations.

In the ordinary course of business, the Company collects and stores sensitive data, including proprietary business information and personally identifiable information of its customers and employees in systems and on networks. The secure processing, maintenance and use of this information is critical to operations and the Company's business strategy. The Company has invested in accepted technologies, and annually reviews processes and practices that are designed to protect its networks, computers and data from damage or unauthorized access. Despite these security measures, the Company's computer systems and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. A breach of any kind could compromise systems and the information stored there could be accessed, damaged or disclosed. A breach in security could result in legal claims, regulatory penalties, disruption in operations, and damage to the Company's reputation, which could adversely affect the Company's business.  Furthermore, as cyberattacks continue to evolve and increase, the Company may be required to expend significant additional resources to modify or enhance its protective measures, or to investigate and remediate any identified information security vulnerabilities.

Multiple major U.S. retailers, financial institutions, government agencies and departments have experienced data systems incursions reportedly resulting in the thefts of credit and debit card information, online account information, and other financial data of tens of millions of individuals and customers. Retailer incursions affect cards issued and deposit accounts maintained by many financial institutions, including the Bank. Although neither the Company's nor the Bank's systems are breached in government or retailer incursions, these events can cause the Bank to reissue a significant number of cards and take other costly steps to avoid significant theft loss to the Bank and its customers.  In some cases, the Bank may be required to reimburse customers for the losses they incur. Other possible points of intrusion or disruption not within the Company's nor the Bank's control include internet service providers, electronic mail portal providers, social media portals, distant-server (so called "cloud") service providers, electronic data security providers, personal computers and mobile phones, telecommunications companies, and mobile phone manufacturers.

The Company’s risk-management framework may not be effective in mitigating risk and loss.

The Company maintains an enterprise risk management program that is designed to identify, quantify, monitor, report, and control the risks that it faces. These risks include, but are not limited to: strategic, interest-rate, credit, liquidity, operations, pricing, reputation, compliance, litigation and cybersecurity. While the Company assesses and improves this program on an ongoing basis, there can be no assurance that its approach and framework for risk management and related controls will effectively mitigate all risk and limit losses in its business. If conditions or circumstances arise that expose flaws or gaps in the Company’s risk-management program, or if its controls break down, the Company’s results of operations and financial condition may be adversely affected.

20

Current and proposed regulation addressing consumer privacy and data use and security could increase the Company's costs and impact its reputation.

The Company is subject to a number of laws concerning consumer privacy and data use and security, including information safeguard rules under the Gramm-Leach-Bliley Act. These rules require that financial institutions develop, implement and maintain a written, comprehensive information security program containing safeguards that are appropriate to the financial institution's size and complexity, the nature and scope of the financial institution's activities, and the sensitivity of any customer information at issue. The United States has experienced a heightened legislative and regulatory focus on privacy and data security, including requiring consumer notification in the event of a data breach. In addition, most states have enacted security breach legislation requiring varying levels of consumer notification in the event of certain types of security breaches.  New regulations in these areas may increase the Company's compliance costs, which could negatively impact earnings. In addition, failure to comply with the privacy and data use and security laws and regulations to which the Company is subject, including by reason of inadvertent disclosure of confidential information, could result in fines, sanctions, penalties or other adverse consequences and loss of consumer confidence, which could materially adversely affect the Company's results of operations, overall business, and reputation.

Consumers may increasingly decide not to use the Bank to complete their financial transactions because of technological and other changes, which would have a material adverse impact on the Company's financial condition and operations.

Technology and other changes are allowing parties to complete financial transactions through alternative methods that historically have involved banks. For example, consumers can now maintain funds that would have historically been held as bank deposits in brokerage accounts, mutual funds or general-purpose reloadable prepaid cards. Consumers can also complete transactions such as paying bills and/or transferring funds directly without the assistance of banks. The process of eliminating banks as intermediaries, known as "disintermediation," could result in the loss of fee income, as well as the loss of customer deposits and the related income generated from those deposits. The loss of these revenue streams and the lower cost of deposits as a source of funds could have a material adverse effect on the Company's financial condition and results of operations.

Negative perception of the Company through media may adversely affect the Company’s reputation and business.

The Company’s reputation is critical to the success of its business. The Company believes that its brand image has been well received by customers, reflecting the fact that the brand image, like the Company’s business, is based in part on trust and confidence. The Company’s reputation and brand image could be negatively affected by rapid and widespread distribution of publicity through social and traditional media channels. The Company’s reputation could also be affected by the Company’s association with clients affected negatively through social and traditional media distribution, or other third parties, or by circumstances outside of the Company’s control. Negative publicity, whether true or untrue, could affect the Company’s ability to attract or retain customers, or cause the Company to incur additional liabilities or costs, or result in additional regulatory scrutiny.

The Company is subject to claims and litigation pertaining to fiduciary responsibility.

From time to time, customers make claims and take legal action pertaining to the performance of the Company's fiduciary responsibilities. Whether customer claims and legal action related to the performance of the Company's fiduciary responsibilities are founded or unfounded, if such claims and legal actions are not resolved in a manner favorable to the Company, they may result in significant financial liability and/or adversely affect the market perception of the Company and its products and services, as well as impact customer demand for those products and services. Any financial liability or reputation damage could have a material adverse effect on the Company's business, which, in turn, could have a material adverse effect on the Company's financial condition and results of operations.

Changes in the federal, state or local tax laws may negatively impact the Company’s financial performance.

Changes in tax law could increase the Company’s effective tax rates. Such changes may be retroactive to previous periods and as a result could negatively affect the Company’s current and future financial performance. The Tax Reform Act, the full impact of which the Company is still analyzing, is likely to have both positive and negative effects on the Company’s financial performance. For example, the new legislation will result in a reduction in federal corporate tax rate from 35% to 21% beginning in 2018, which will have a favorable impact on the Company’s earnings and capital generation abilities. However, the new legislation also enacted limitations on certain deductions, such as the deduction of FDIC deposit insurance premiums, which will partially offset the anticipated increase in net earnings from the lower tax rate. In addition, as a result of the lower corporate tax rate, the Company revalued its ending net deferred tax assets at December 31, 2017 and recognized a provisional $2.7 million tax expense in the Company’s consolidated statement of income for the year ended December 31, 2017. The impact of the Tax Reform Act may differ from the foregoing, possibly materially, due to changes in interpretations or in assumptions that the Company has made, guidance or regulations that may be promulgated, and other actions that the Company

21

may take as a result of the Tax Reform Act. Similarly, the Company’s customers are likely to experience varying effects from both the individual and business tax provisions of the Tax Reform Act and such effects, whether positive or negative, may have a corresponding impact on the Company’s business and the economy as a whole.

Severe weather, natural disasters, acts of war or terrorism, and other external events could significantly impact the Company’s business.

Severe weather, natural disasters, acts of war or terrorism, and other adverse external events could have a significant impact on the Company’s ability to conduct business. In addition, such events could affect the stability of the Company’s deposit base, impair the ability of borrowers to repay outstanding loans, impair the value of collateral securing loans, cause significant property damage, result in loss of revenue, and/or cause the Company to incur additional expenses. The occurrence of any such event in the future could have a material adverse effect on the Company’s business, which, in turn, could have a material adverse effect on its financial condition and results of operations.

Risks Related to the Company's Common Stock

While the Company's common stock is currently traded on the Nasdaq Global Select Market, it has less liquidity than stocks for larger companies quoted on a national securities exchange.

The trading volume in the Company's common stock on the Nasdaq Global Select Market has been relatively low when compared with larger companies listed on the Nasdaq Global Select Market or other stock exchanges.  There is no assurance that a more active and liquid trading market for the common stock will exist in the future.  Consequently, shareholders may not be able to sell a substantial number of shares for the same price at which shareholders could sell a smaller number of shares.  In addition, we cannot predict the effect, if any, that future sales of the Company's common stock in the market, or the availability of shares of common stock for sale in the market, will have on the market price of the common stock.

Economic and other conditions may cause volatility in the price of the Company’s common stock.

In the current economic environment, the prices of publicly traded stocks in the financial services sector have been volatile. However, even in a more stable economic environment the price of the Company’s common stock can be affected by a variety of factors such as expected or actual results of operations, changes in analysts’ recommendations or projections, announcements of developments related to its businesses, operating and stock performance of other companies deemed to be peers, news or expectations based on the performance of others in the financial services industry, and expected impacts of a changing regulatory environment. These factors not only impact the price of the Company’s common stock but could also affect the liquidity of the stock given the Company’s size, geographical footprint, and industry. The price for shares of the Company’s common stock may fluctuate significantly in the future, and these fluctuations may be unrelated to the Company’s performance. General market price declines or market volatility in the future could adversely affect the price for shares of the Company’s common stock, and the current market price of such shares may not be indicative of future market prices.

Future issuances of the Company's common stock could adversely affect the market price of the common stock and could be dilutive.

The Company is not restricted from issuing additional shares of common stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, shares of common stock.  Issuances of a substantial number of shares of common stock, or the expectation that such issuances might occur, including in connection with acquisitions by the Company, could materially adversely affect the market price of the shares of the common stock and could be dilutive to shareholders.  Because the Company's decision to issue common stock in the future will depend on market conditions and other factors, it cannot predict or estimate the amount, timing or nature of possible future issuances of its common stock.  Accordingly, the Company's shareholders bear the risk that future issuances will reduce the market price of the common stock and dilute their stock holdings in the Company.

The primary source of the Company's income from which it pays cash dividends is the receipt of dividends from its subsidiary bank.

The availability of dividends from the Company is limited by various statutes and regulations.  It is possible, depending upon the financial condition of the Bank and other factors, that the OCC could assert that payment of dividends or other payments is an unsafe or unsound practice.  In the event the Bank was unable to pay dividends to the Company, or be limited in the payment of such dividends, the Company would likely have to reduce or stop paying common stock dividends.  The Company's reduction, limitation or failure to pay such dividends on its common stock could have a material adverse effect on the market price of the common stock.

22

The Company's governing documents and Virginia law contain anti-takeover provisions that could negatively impact its shareholders.

The Company's Articles of Incorporation and Bylaws and the Virginia Stock Corporation Act contain certain provisions designed to enhance the ability of the Company's Board of Directors to deal with attempts to acquire control of the Company.  These provisions and the ability to set the voting rights, preferences and other terms of any series of preferred stock that may be issued, may be deemed to have an anti-takeover effect and may discourage takeovers (which certain shareholders may deem to be in their best interest).  To the extent that such takeover attempts are discouraged, temporary fluctuations in the market price of the Company's common stock resulting from actual or rumored takeover attempts may be inhibited.  These provisions also could discourage or make more difficult a merger, tender offer, or proxy contest, even though such transactions may be favorable to the interests of shareholders, and could potentially adversely affect the market price of the Company's common stock.

ITEM 2 – PROPERTIES

As of December 31, 2017, the Company maintained twenty-six banking offices.  The Company's Virginia banking offices are located in the cities of Danville, Martinsville, Lynchburg, and in the counties of Bedford, Campbell, Franklin, Halifax, Henry, Pittsylvania and Roanoke.  In North Carolina, the Company's banking offices are located in the cities of Burlington, Graham, Greensboro, Mebane and Winston-Salem and in the counties of Alamance, Caswell, and Guilford.  The Company also operates two loan production offices.

ITEM 3 – LEGAL PROCEEDINGS

In the ordinary course of operations, the Company and the Bank are parties to various legal proceedings. Based upon information currently available, management believes that such legal proceedings, in the aggregate, will not have a material adverse effect on the business, financial condition, or results of operations of the Company.

ITEM 4 – MINE SAFETY DISCLOSURES

The Company’s future dividend policy is subject to the discretion of the Boards of Directors of the Company and the Bank and will depend upon a number of factors, including future earnings, financial condition, cash requirements and general business conditions. The Company and the Bank are also subject to certain restrictions imposed by the reserve and capital requirements of federal and state statutes and regulations. See “Part I, Item 1. Business - Supervision and Regulation - Dividends,” for information on regulatory restrictions on dividends.

Stock Compensation Plans

Until its expiration date on February 18, 2018, the Company maintained the 2008 Stock Incentive Plan ("2008 Plan"), which was designed to attract and retain qualified personnel in key positions, provide employees with an equity interest in the Company as an incentive to contribute to the success of the Company, and reward employees for outstanding performance and the attainment of targeted goals. The 2008 Plan and stock compensation in general is discussed in Note 12 of the Consolidated Financial Statements contained in Item 8 of this Form 10-K.

Stock Repurchase Program

On November 19, 2015, the Company filed a Form 8-K with the SEC to announce the approval by its Board of Directors (the "Board") of a stock repurchase program. The program authorized the repurchase of up to 300,000 shares of the Company's common shares over a two year period. The share purchase limit was equal to approximately 3.5% of the 8,622,000 common shares then outstanding at the time the Board approved the program. The program expired on November 19, 2017.

During 2017, the Company did not repurchase any shares. In 2016, the Company repurchased 51,384 shares at an average cost of $25.14 per share, for a total cost of $1,292,000.

On January 19, 2018, the Company filed a Form 8-K with the SEC to announce the approval by its Board of another stock repurchase program. The program authorizes the repurchase of up to 300,000 shares of the Company's common stock over a two year period.

(1) Return on average common equity is calculated by dividing net income available to common shareholders by average common equity.

(2) Return on average tangible common equity is calculated by dividing net income available to common shareholders plus amortization of intangibles tax effected by average common equity less average intangibles.

(3) The efficiency ratio is calculated by dividing noninterest expense excluding gains or losses on the sale of other real estate owned by net interest income including tax equivalent income on nontaxable loans and securities and noninterest income and excluding (a) gains or losses on securities and (b) gains or losses on sale of premises and equipment.

(4) Tangible equity to tangible assets ratio is calculated by dividing period-end common equity less period-end intangibles by period-end assets less period-end intangibles.

ITEM 7 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The purpose of this discussion is to focus on significant changes in the financial condition and results of operations of the Company during the past three years.  The discussion and analysis are intended to supplement and highlight information contained in the accompanying Consolidated Financial Statements and the selected financial data presented elsewhere in this Annual Report on Form 10-K.

RECLASSIFICATION

In certain circumstances, reclassifications have been made to prior period information to conform to the 2017 presentation.  There were no material reclassifications.

CRITICAL ACCOUNTING POLICIES

The accounting and reporting policies followed by the Company conform with GAAP and they conform to general practices within the banking industry.  The Company's critical accounting policies, which are summarized below, relate to (1) the allowance for loan losses, (2) mergers and acquisitions, (3) acquired loans with specific credit-related deterioration, (4) goodwill and intangible assets, (5) other real estate owned, (6) deferred tax assets and liabilities, (7) other-than-temporary impairment of securities and (8) the unfunded pension liability.  A summary of the Company's significant accounting policies is set forth in Note 1 to the Consolidated Financial Statements.

The financial information contained within the Company's financial statements is, to a significant extent, financial information that is based on measures of the financial effects of transactions and events that have already occurred.  A variety of factors could affect the ultimate value that is obtained when earning income, recognizing an expense, recovering an asset, or relieving a liability.  In addition, GAAP itself may change from one previously acceptable method to another method.

Allowance for Loan Losses

The purpose of the allowance for loan losses ("ALLL") is to provide for probable losses inherent in the loan portfolio.  The allowance is increased by the provision for loan losses and by recoveries of previously charged-off loans.  Loan charge-offs decrease the allowance.

The goal of the Company is to maintain an appropriate, systematic, and consistently applied process to determine the amounts of the ALLL and the provision for loan loss expense.

The Company uses certain practices to manage its credit risk.  These practices include (1) appropriate lending limits for loan officers, (2) a loan approval process, (3) careful underwriting of loan requests, including analysis of borrowers, cash flows, collateral, and market risks, (4) regular monitoring of the portfolio, including diversification by type and geography, (5) review of loans by the Loan Review department, which operates independently of loan production (the Loan Review function consists of a co-sourced arrangement using both internal personnel and external vendors to provide the Company with a more robust review function of the loan portfolio), (6) regular meetings of the Credit Committee to discuss portfolio and policy changes and make decisions on large or unusual loan requests, and (7) regular meetings of the Asset Quality Committee which reviews the status of individual loans.

Risk grades are assigned as part of the loan origination process. From time to time, risk grades may be modified as warranted by the facts and circumstances surrounding the credit.

Calculation and analysis of the ALLL is prepared quarterly by the Finance Department.  The Company's Credit Committee, Capital Management Committee, Audit Committee, and the Board of Directors review the allowance for adequacy.

28

The Company's ALLL has two basic components:  the formula allowance and the specific allowance.  Each of these components is determined based upon estimates and judgments.

The formula allowance uses historical loss experience as an indicator of future losses, along with various qualitative factors, including levels and trends in delinquencies, nonaccrual loans, charge-offs and recoveries, trends in volume and terms of loans, effects of changes in underwriting standards, experience of lending staff, economic conditions, and portfolio concentrations, regulatory, legal, competition, quality of loan review system, and value of underlying collateral. In the formula allowance for commercial and commercial real estate loans, the historical loss rate is combined with the qualitative factors, resulting in an adjusted loss factor for each risk-grade category of loans.  The period-end balances for each loan risk-grade category are multiplied by the adjusted loss factor.  Allowance calculations for residential real estate and consumer loans are calculated based on historical losses for each product category without regard to risk grade. This loss rate is combined with qualitative factors resulting in an adjusted loss factor for each product category.

The specific allowance uses various techniques to arrive at an estimate of loss for specifically identified impaired loans. These include:

• The present value of expected future cash flows discounted at the loan's effective interest rate.  The effective interest rate on a loan is the rate of return implicit in the loan (that is, the contractual interest rate adjusted for any netdeferred loan fees or costs and any premium or discount existing at the origination or acquisition of the loan);

• The loan's observable market price, or

• The fair value of the collateral, net of estimated costs to dispose, if the loan is collateral dependent.

The use of these computed values is inherently subjective and actual losses could be greater or less than the estimates.

No single statistic, formula, or measurement determines the adequacy of the allowance.  Management makes subjective and complex judgments about matters that are inherently uncertain, and different amounts would be reported under different conditions or using different assumptions.  For analytical purposes, management allocates a portion of the allowance to specific loan categories and specific loans.  However, the entire allowance is used to absorb credit losses inherent in the loan portfolio, including identified and unidentified losses.

The relationships and ratios used in calculating the allowance, including the qualitative factors, may change from period to period as facts and circumstances evolve.  Furthermore, management cannot provide assurance that in any particular period the Bank will not have sizeable credit losses in relation to the amount reserved.  Management may find it necessary to significantly adjust the allowance, considering current factors at the time.

Mergers and Acquisitions

Business combinations are accounted for under the Financial Accounting Standards Board (the "FASB") Accounting Standards Codification ("ASC") 805, Business Combinations, using the acquisition method of accounting. The acquisition method of accounting requires an acquirer to recognize the assets acquired and the liabilities assumed at the acquisition date measured at their fair values as of that date. To determine the fair values, the Company will rely on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analysis or other valuation techniques. Under the acquisition method of accounting, the Company will identify the acquirer and the closing date and apply applicable recognition principles and conditions.

Acquisition-related costs are costs the Company incurs to effect a business combination. Those costs include advisory, legal, accounting, valuation, and other professional or consulting fees. Some other examples of costs to the Company include systems conversions, integration planning, consultants, and advertising costs. The Company will account for acquisition-related costs as expenses in the periods in which the costs are incurred and the services are received, with one exception. The costs to issue debt or equity securities will be recognized in accordance with other applicable GAAP. These acquisition-related costs have been and will be included within the Consolidated Statements of Income classified within the noninterest expense caption.

Acquired Loans with Specific Credit-Related Deterioration

Acquired loans with specific credit deterioration are accounted for by the Company in accordance with FASB ASC 310-30, Receivables - Loans and Debt Securities Acquired with Deteriorated Credit Quality. Certain acquired loans, those for which specific credit-related deterioration, since origination, is identified, are recorded at fair value reflecting the present value of the amounts expected to be collected. Income recognition on these loans is based on a reasonable expectation about the timing and amount of cash flows to be collected. Acquired loans deemed impaired and considered collateral dependent, with the timing of the sale of loan collateral indeterminate, remain on non-accrual status and have no accretable yield.

29

Goodwill and Intangible Assets

The Company follows ASC 350, Goodwill and Other Intangible Assets, which prescribes the accounting for goodwill and intangible assets subsequent to initial recognition. Goodwill resulting from business combinations prior to January 1, 2009 represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009 is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exists that indicate that a goodwill impairment test should be performed. The Company has selected June 30 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives, which range from 8.25 to 10 years, to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on the Company’s consolidated balance sheets. No indicators of impairment were identified during the years ended December 31, 2017, 2016, or 2015.

Other Real Estate Owned

Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less costs to sell at the date of foreclosure. Subsequent to foreclosure, management periodically performs valuations of the foreclosed assets based on updated appraisals, general market conditions, recent sales of similar properties, length of time the properties have been held, and our ability and intention with regard to continued ownership of the properties. The Company may incur additional write-downs of foreclosed assets to fair value less costs to sell if valuations indicate a further deterioration in market conditions.

Deferred Tax Assets and Liabilities

The realization of deferred income tax assets is assessed and a valuation allowance is recorded if it is “more likely than not” that all or a portion of the deferred tax asset will not be realized.  “More likely than not” is defined as greater than a 50% chance. Management considers all available evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance is needed.

Other-than-temporary Impairment of Securities

Impairment of securities occurs when the fair value of a security is less than its amortized cost. For debt securities, impairment is considered other-than-temporary and recognized in its entirety in net income if either (i) we intend to sell the security or (ii) it is more-likely-than-not that we will be required to sell the security before recovery of its amortized cost basis. If, however, we do not intend to sell the security and it is not more-likely-than-not that we will be required to sell the security before recovery, we must determine what portion of the impairment is attributable to a credit loss, which occurs when the amortized cost basis of the security exceeds the present value of the cash flows expected to be collected from the security. If there is no credit loss, there is no other-than-temporary impairment. If there is a credit loss, other-than-temporary impairment exists, and the credit loss must be recognized in net income and the remaining portion of impairment must be recognized in other comprehensive income. For equity securities, impairment is considered to be other-than-temporary based on our ability and intent to hold the investment until a recovery of fair value. Other-than-temporary impairment of an equity security results in a write-down that must be included in net income. We regularly review each investment security for other-than-temporary impairment based on criteria that includes the extent to which cost exceeds market price, the duration of that market decline, the financial health of and specific prospects for the issuer, our best estimate of the present value of cash flows expected to be collected from debt securities, our intention with regard to holding the security to maturity and the likelihood that we would be required to sell the security before recovery.

Unfunded Pension Liability

The Company previously maintained a non-contributory, defined benefit pension plan for eligible full-time employees as specified by the plan. The Company froze its pension plan to new participants and converted its pension plan to a cash balance plan effective December 31, 2009. Plan assets, which consist primarily of mutual funds invested in marketable equity securities and corporate and government fixed income securities, are valued using market quotations. The Company’s actuary determines plan obligations and annual pension expense using a number of key assumptions. Key assumptions may include the discount rate, the interest crediting rate, the estimated future return on plan assets and the anticipated rate of future salary increases. Changes in these assumptions in the future, if any, or in the method under which benefits are calculated may impact pension assets, liabilities or expense.

NON-GAAP PRESENTATIONS

Non-GAAP presentations are provided because the Company believes these may be valuable to investors. These include (1) the calculation of the efficiency ratio and (2) the analysis of net interest income presented on a taxable equivalent basis to facilitate performance comparisons among various taxable and tax-exempt assets.

The efficiency ratio is calculated by dividing noninterest expense excluding gains or losses on the sale of other real estate owned ("OREO") by net interest income including tax equivalent income on nontaxable loans and securities and noninterest income and excluding (i) gains or losses on securities and (ii) gains or losses on sale of premises and equipment. The efficiency ratio for 2017, 2016, and 2015 was 60.89%, 61.47%, and 63.81%, respectively. The Company expects continued improvement in this ratio in 2018. This is a non-GAAP financial measure that the Company believes provides investors with important information regarding operational efficiency. Such information is not prepared in accordance with GAAP and should not be construed as such. Management believes, however, such financial information is meaningful to the reader in understanding operating performance, but cautions that such information not be viewed as a substitute for GAAP. The Company, in referring to its net income, is referring to income under GAAP. The components of the efficiency ratio calculation are summarized in the following table (dollars in thousands):

	Year Ended December 31,

Efficiency ratio	60.89		%	61.47		%	63.81		%

31

Net interest margin is calculated by dividing tax equivalent net interest income by total average earning assets. Because a portion of interest income earned by the Company is nontaxable, the tax equivalent net interest income is considered in the calculation of this ratio. Tax equivalent net interest income is calculated by adding the tax benefit realized from interest income that is nontaxable to total interest income then subtracting total interest expense. The tax rate utilized in calculating the tax benefit for 2017, 2016 and 2015 is 35%. The reconciliation of tax equivalent net interest income, which is not a measurement under GAAP, to net interest income, is reflected in the table below (in thousands):

STRATEGIC EVENT

In the fall of 2016, the Company announced the opening of a de novo branch in each of Roanoke, Virginia and Winston-Salem, North Carolina. Current staffing for Roanoke includes sixteen full-time equivalent employees, of which eight are lenders. Current staffing for Winston-Salem includes six full-time equivalent employees, of which three are lenders. The operations of these new branches positively impacted earning assets, deposits and operating results for 2017.

RESULTS OF OPERATIONS

Net Income

Net income for 2017 was $15,249,000 compared to $16,301,000 for 2016, a decrease of $1,052,000 or 6.5%. Basic and diluted earnings per share were $1.76 for 2017 compared to $1.89 for 2016. This net income produced for 2017 a return on average assets of 0.87%, a return on average equity of 7.34%, and a return on average tangible equity of 9.59%.

Although the corporate tax rate reduction from 35% to 21% enacted into law by the Tax Reform Act becomes effective in 2018, the enactment required companies to revalue their deferred tax assets at the new tax rate in 2017. Accordingly, in December 2017 the Company recognized a $2.7 million charge ($0.31 per share) to its deferred tax asset and a corresponding increase in income tax expense. Without the impact of the one-time deferred tax write-down, net income for 2017 would have been $17.9 million, an increase of $1.6 million compared to 2016. Basic and diluted earnings per share would have been $2.07.

Net income for 2016 was $16,301,000 compared to $15,039,000 for 2015, an increase of $1,262,000 or 8.4%. Basic and diluted earnings per share were $1.89 for 2016 compared to $1.73 for 2015. This net income produced for 2016 a return on average assets of 1.02%, a return on average equity of 8.07%, and a return on average tangible equity of 10.85%.

Earnings for 2017, 2016, and 2015 were favorably impacted by the 2011 acquisition of MidCarolina Financial Corporation ("MidCarolina") and the 2015 acquisition of MainStreet. The financial impact of the mergers was mostly a significant increase in earning assets.

Net Interest Income

Net interest income is the difference between interest income on earning assets, primarily loans and securities, and interest expense on interest bearing liabilities, primarily deposits. Fluctuations in interest rates as well as volume and mix changes in earning assets and interest bearing liabilities can materially impact net interest income. The 2011 acquisition of MidCarolina

32

and the 2015 acquisition of MainStreet impacted net interest income positively for 2017, 2016 and 2015, through increased earning assets.

The following discussion of net interest income is presented on a taxable equivalent basis to facilitate performance comparisons among various taxable and tax-exempt assets, such as certain state and municipal securities. A tax rate of 35% was used in adjusting interest on tax-exempt assets to a fully taxable equivalent basis. Net interest income divided by average earning assets is referred to as the net interest margin. The net interest spread represents the difference between the average rate earned on earning assets and the average rate paid on interest bearing liabilities. All references in this section relate to average yields and rates and average asset and liability balances during the periods discussed.

Net interest income on a taxable equivalent basis increased $5,386,000 or 10.4% in 2017 from 2016, following a $421,000 or 0.8% increase in 2016 from 2015. The increase in net interest income in 2017 was primarily due to increased volumes of earning assets related to organic growth.

Yields on loans were 4.39% in 2017 compared to 4.54% in 2016. Cost of funds was 0.64% in 2017 compared to 0.60% in 2016. Between 2017 and 2016, deposit rates for demand accounts decreased to 0.02% from 0.05%, money market accounts increased to 0.50% from 0.18%, and time deposits decreased to 1.05% from 1.14%. The increase in money market rates was related mainly to high dollar volume commercial and municipal customer accounts. Management regularly reviews deposit pricing and attempts to keep costs as low as possible, while remaining competitive. The net interest margin was 3.50% for 2017, 3.52% for 2016, and 3.69% for 2015.

During 2008, the Federal Open Market Committee ("FOMC") of the FRB reduced the federal funds rate seven times from 4.25% to 0.25%, where it remained, unchanged, through mid December 2015. On December 17, 2015, the FOMC raised the target federal funds rate from 0.25% to 0.50%. On December 15, 2016, the FOMC raised the target federal funds rate from 0.50% to 0.75%. The FOMC raised the target federal funds rate by 0.25% on March 15, June 14, and December 13, 2017, ending the year at 1.50%. The increase in rates is expected to have a nominal positive impact on net interest income. Given recent economic and geopolitical events in 2017 and early 2018, the federal funds rate may be higher at year end 2018, but there is uncertainty and the Company cannot predict as to how much higher it may be.

Net interest income on a taxable equivalent basis increased $421,000 or 0.8% in 2016 from 2015, following a $7,466,000 or 17.0% increase in 2015 from 2014. The increase in net interest income in 2016 was primarily due to increased volumes of earning assets related to organic growth.

Yields on loans were 4.54% in 2016 compared to 4.81% in 2015. Cost of funds was 0.60% in 2016 compared to 0.58% in 2015. Between 2016 and 2015, deposit rates for demand accounts increased to 0.05% from 0.04%, money market accounts increased to 0.18% from 0.13%, and time deposits increased to 1.14% from 1.09%. Management regularly reviews deposit pricing and attempts to keep costs as low as possible, while remaining competitive. The net interest margin was 3.52% for 2016, 3.69% for 2015, and 3.66% for 2014.

The following presentation is an analysis of net interest income and related yields and rates, on a taxable equivalent basis, for the last three years. Nonaccrual loans are included in average balances. Interest income on nonaccrual loans, if recognized, is recorded on a cash basis or when the loan returns to accrual status.

Noninterest Income

For the year ended December 31, 2017, noninterest income increased $722,000 or 5.3% compared to the year ended December 31, 2016.

A substantial portion of trust fees are earned based on account fair values, so changes in the equity markets may have a large and potentially volatile impact on revenue. Trust fees increased slightly while service charges decreased slightly for 2017 compared to 2016. Other fees and commissions were positively impacted by higher levels of debit card transaction volume. Mortgage banking income increased significantly in 2017 as a result of increases in the volume of originations. Also, the Bank added new mortgage originators in the Roanoke market in the fourth quarter of 2016 and the second quarter of 2017. Secondary market mortgage loan volume for 2017 was $86,612,000 compared to $78,330,000 for 2016. Income from Small Business Investment Company ("SBIC") investments, which is volatile and difficult to predict, decreased $227,000 or 49.0% for 2017 compared to 2016. Net gains (losses) on premises and equipment increased $353,000 for 2017 compared to 2016 primarily due to a $337,000 gain from the sale of a bank owned commercial lot acquired in the MidCarolina acquisition. Other income decreased $165,000 for 2017 compared to 2016 primarily due to the additional income from investments in limited partnerships in 2016.

Noninterest Expense

For the year ended December 31, 2017, noninterest expense increased $3,082,000 or 7.7% as compared to the year ended December 31, 2016.

Salaries expense increased $2,261,000, or 12.9%, in 2017 compared to 2016. The increase in salaries expense and employee benefits expense resulted primarily due to the addition of eight full time equivalent employees during 2017. The Bank added two mortgage loan originators, a trust officer, and several branch level personnel. On the support side of the Bank, additions were made to the credit function, risk, and loan review. The expense for FDIC assessment decreased in 2017 due to the reduction in FDIC assessment rates effective the third quarter of 2016. Core deposit intangible amortization decreased in 2017 compared to 2016 as the amortization expense relating to the Company's acquisition of MidCarolina in July 2011 recognized under the accelerated method and will likely be fully amortized in 2020. The increase of $639,000 in other expenses for 2017 compared to 2016 is primarily due to increased marketing and printing for marketing campaigns and the de novo branch openings in 2017.

Salaries expense increased $1,014,000, or 6.1%, in 2016 compared to 2015. The major driver of this increase is additional compensation expense related to the de novo efforts in Roanoke, Virginia and Winston-Salem, North Carolina. The expense for FDIC assessment decreased in 2016 due to the reduction in FDIC assessment rates effective the third quarter of 2016. Other real estate owned expense includes gains and losses on sale of foreclosed properties, adjustments related to re-appraisals of

37

foreclosed properties, and operating expenses related to maintaining foreclosed properties. It is inherently volatile from period to period. The change in other real estate owned expense during 2016 was primarily a result of the gain on the sale of one foreclosed property in the amount of $183,000 during 2015. The largest component of the decrease in noninterest expense in 2016 was the 2015 nonrecurring merger related expenses of $1,998,000.

OREO expense includes gains and losses on sale of foreclosed properties, adjustments related to re-appraisals of foreclosed properties, and operating expenses related to maintaining foreclosed properties. The activity related to this noninterest expense for the years ended December 31, 2017, 2016, and 2015 is shown below (dollars in thousands):

Income Taxes

Income taxes on 2017 earnings amounted to $10,826,000, resulting in an effective tax rate of 41.5%, compared to 30.1% in 2016 and 28.6% in 2015. Income tax expense for 2017 includes a one-time write-down of net deferred tax assets in the amount of $2.7 million, recorded as a result of the enactment of the Tax Reform Act on December 22, 2017. The Tax Reform Act reduces the federal corporate tax rate from 35% to 21% effective January 1, 2018.

The effective tax rate is lowered by income that is not taxable for federal income tax purposes. The primary non-taxable income is from state and municipal securities and loans.

Fair Value Impact to Pretax Income

The July 2011 merger with MidCarolina and the January 2015 merger with MainStreet had a material and positive impact on earnings. The ongoing financial impact of the mergers was mostly the result of the increase in earnings assets. However, the specific financial impact of the fair value related accounting adjustments is reflected in the following tables. The tables present the actual effect of the accretable and amortizable fair value adjustments attributable to the mergers on net interest income and pretax income for the years ended December 31, 2017, 2016, and 2015, respectively (dollars in thousands):

Generally accepted accounting principles for business combinations require the acquired balance sheet to be valued at fair value at the time of the merger. In the context of acquiring a commercial bank, most of the balance sheet is interest rate sensitive and this can generate significant discounts or premiums to contractual values. These discounts or premiums will have potentially significant impact to net interest income and to net income.

The table below summarizes the impact of the fair value merger related accounting impact to net interest income and impact to pretax income of the MidCarolina (for table immediately below, "MC") and MainStreet (for table immediately below, "MS") acquisitions (dollars in thousands):

For the Years Ended December 31,	2017									2016									2015
	MC			MS			Total			MC			MS			Total			MC			MS			Total
Net interest income	$	1,167		$	947		$	2,114		$	1,450		$	868		$	2,318		$	2,268		$	929		$	3,197

The MidCarolina acquisition was effective July 1, 2011. The MainStreet acquisition was effective January 1, 2015. Management expects that the fair value accounting financial impact of both acquisitions will continue to decline in subsequent quarters.

Impact of Inflation and Changing Prices

The majority of assets and liabilities of a financial institution are monetary in nature and therefore differ greatly from most commercial and industrial companies that have significant investments in fixed assets or inventories. The most significant effect of inflation is on noninterest expenses that tend to rise during periods of inflation.  Changes in interest rates have a greater impact on a financial institution's profitability than do the effects of higher costs for goods and services. Through its balance sheet management practices, the Company has the ability to react to those changes and measure and monitor its interest rate and liquidity risk.

Effectively managing market risk is essential to achieving the Company's financial objectives. Market risk reflects the risk of economic loss resulting from changes in interest rates and market prices. The Company is generally not subject to currency exchange risk or commodity price risk. The Company's primary market risk exposure is interest rate risk; however, market risk also includes liquidity risk. Both are discussed in the following sections.

Interest Rate Risk Management

Interest rate risk and its impact on net interest income is a primary market risk exposure. The Company manages its exposure to fluctuations in interest rates through policies approved by its Asset Liability Committee ("ALCO") and Board of Directors, both of which receive and review periodic reports of the Company's interest rate risk position.

The Company uses computer simulation analysis to measure the sensitivity of projected earnings to changes in interest rates. Simulation takes into account current balance sheet volumes and the scheduled repricing dates, instrument level optionality, and maturities of assets and liabilities. It incorporates numerous assumptions including growth, changes in the mix of assets and liabilities, prepayments, and average rates earned and paid. Based on this information, management uses the model to project net interest income under multiple interest rate scenarios.

A balance sheet is considered asset sensitive when its earning assets (loans and securities) reprice faster or to a greater extent than its liabilities (deposits and borrowings). An asset sensitive balance sheet will produce relatively more net interest income when interest rates rise and less net interest income when they decline. Based on the Company's simulation analysis, management believes the Company's interest sensitivity position at December 31, 2017 is asset sensitive. As of early 2018, management expects that the general direction of market interest rates will be stable to up, though volatility, sometimes substantial, is anticipated in the short-term.

Earnings Simulation

The table below shows the estimated impact of changes in interest rates on net interest income as of December 31, 2017 (dollars in thousands), assuming gradual and parallel changes in interest rates, and consistent levels of assets and liabilities.  Net interest income for the following twelve months is projected to increase when interest rates are higher than current rates.

Estimated Changes in Net Interest Income

	Change in net interest income
Change in interest rates	Amount			Percent
Up  4.0%	$	10,089		17.2	%
Up  3.0%	7,837			13.3
Up  2.0%	6,497			9.3

Flat	—			—
Down 0.25%	(916		)	(1.6	)
Down 0.50%	(2,048		)	(3.5	)

Management cannot predict future interest rates or their exact effect on net interest income. Computations of future effects of hypothetical interest rate changes are based on numerous assumptions and should not be relied upon as indicative of actual results. Certain limitations are inherent in such computations. Assets and liabilities may react differently than projected to changes in market interest rates. The interest rates on certain types of assets and liabilities may fluctuate in advance of changes in market interest rates, while rates on other types of assets and liabilities may lag changes in market interest rates. Interest rate shifts may not be parallel.

Changes in interest rates can cause substantial changes in the amount of prepayments of loans and mortgage-backed securities, which may in turn affect the Company's interest rate sensitivity position. Additionally, credit risk may rise if an interest rate increase adversely affects the ability of borrowers to service their debt.

Economic Value Simulation

Economic value simulation is used to calculate the estimated fair value of assets and liabilities over different interest rate environments. Economic values are calculated based on discounted cash flow analysis. The net economic value of equity is the economic value of all assets minus the economic value of all liabilities. The change in net economic value over different rate environments is an indication of the longer-term earnings capability of the balance sheet. The same assumptions are used in the economic value simulation as in the earnings simulation. The economic value simulation uses instantaneous rate shocks to the balance sheet.

The following table reflects the estimated change in net economic value over different rate environments using economic value simulation for the balances at the period ended December 31, 2017 (dollars in thousands):

Liquidity Risk Management

Liquidity is the ability of the Company in a timely manner to convert assets into cash or cash equivalents without significant loss and to raise additional funds by increasing liabilities. Liquidity management involves maintaining the Company's ability to meet the daily cash flow requirements of its customers, whether they are borrowers requiring funds or depositors desiring to withdraw funds. Additionally, the Company requires cash for various operating needs including dividends to shareholders, the servicing of debt, and the payment of general corporate expenses. The Company manages its exposure to fluctuations in interest rates and liquidity needs through policies approved by the ALCO and Board of Directors, both of which receive periodic reports of the Company's interest rate risk and liquidity position. The Company uses a computer simulation model to assist in the management of the future liquidity needs of the Company.

Liquidity sources include on balance sheet and off balance sheet sources.

Balance sheet liquidity sources include cash, amounts due from banks, loan repayments, bond maturities and calls, and increases in deposits. Further, the Company maintains a large, high quality, very liquid bond portfolio, which is generally 50% to 60% unpledged and would, accordingly, be available for sale if necessary.

Off balance sheet sources include lines of credit from the Federal Home Loan Bank of Atlanta ("FHLB"), federal funds lines of credit, and access to the Federal Reserve Bank of Richmond's discount window.

The Company has a line of credit with the FHLB, equal to 30% of the Company's assets, subject to the amount of collateral pledged. Under the terms of its collateral agreement with the FHLB, the Company provides a blanket lien covering all of its residential first mortgage loans, home equity lines of credit, commercial real estate loans and commercial construction loans. In addition, the Company pledges as collateral its capital stock in and deposits with the FHLB. At December 31, 2017, principal advance obligations to the FHLB consisted of $24,000,000 in variable-rate, short-term advances compared to $9,980,000 in fixed-rate, long-term advances and $20,000,000 in variable-rate, short-term advances at December 31, 2016. The Company also had outstanding $190,700,000 in letters of credit at December 31, 2017 compared to $130,700,000 in letters of credit at December 31, 2016. The letters of credit provide the Bank with additional collateral for securing public entity deposits above FDIC insurance levels, thereby providing less need for collateral pledging from the securities portfolio and accordingly increasing our balance sheet liquidity.

Short-term borrowing is discussed in Note 9 and long-term borrowing is discussed in Note 10 of the Consolidated Financial Statements contained in Item 8 of this Form 10-K.

The Company has federal funds lines of credit established with two correspondent banks in the amounts of $15,000,000 each and has access to the Federal Reserve Bank of Richmond's discount window. There were no amounts outstanding under these facilities at December 31, 2017. The Company, through its subsidiary bank, has a relationship with Promontory Network, the sponsoring entity for the Certificate of Deposit Account Registry Service® ("CDARS"). Through CDARS, the Company is able to provide deposit customers with access to aggregate FDIC insurance in amounts far exceeding $250,000. This gives the Company the ability, as and when needed, to attract and retain large deposits from insurance sensitive customers. CDARS are classified as brokered deposits, however they are generally derived from customers with whom our institution has or wishes to have a direct and ongoing core deposit relationship. As a result, management considers these deposits functionally, though not technically, in the same category as core deposits. With CDARS, the Company has the option to keep deposits on balance sheet or sell them to other members of the network. Additionally, subject to certain limits, the Company can use CDARS to purchase cost-effective funding without collateralization and in lieu of generating funds through traditional brokered CDs or the FHLB. Thus, CDARS serves as a deposit-gathering tool and an additional liquidity management tool. Deposits through the CDARS program as of December 31, 2017 and 2016 were $25,838,000 and $23,445,000, respectively.

The Bank also participates with the Promontory Network using Insured Cash Sweep®, a product which provides the Bank the capability of providing additional deposit insurance to customers in the context of a money market account arrangement. The product is analogous to the CDARS product discussed above.

Management believes that these sources provide sufficient and timely liquidity, both on and off balance sheet.

BALANCE SHEET ANALYSIS

Securities

The securities portfolio generates income, plays a strategic role in the management of interest rate sensitivity, provides a source of liquidity, and is used to meet collateral requirements. The securities portfolio consists of high quality investments, mostly federal agency, mortgage-backed, and state and municipal securities.

42

The Company is cognizant of the continuing historically low and recently volatile interest rate environment and has elected to maintain a defensive asset liability strategy of purchasing high quality taxable securities of relatively short duration and somewhat longer term tax exempt securities, whose market values are not as volatile in rising rate environments as similar termed taxable investments.

The following table presents information on the amortized cost, maturities, and taxable equivalent yields of securities at the end of the last three years (dollars in thousands):

During 2016, the Company's investment in preferred stock was converted to common stock. At December 31, 2017, the Company had three common stock investments, none of which was paying dividends, with a total amortized cost of $1,384,000.

Loans

The loan portfolio consists primarily of commercial and residential real estate loans, commercial loans to small and medium-sized businesses, construction and land development loans, and home equity loans.

43

Average loans increased $202,172,000 or 19.0% from 2016 to 2017. Average loans increased $87,417,000 or 9.0% from 2015 to 2016.

At December 31, 2017, total loans were $1,336,125,000 an increase of $171,304,0000 or 14.7% from the prior year. The increase is primarily the result of broad based organic loan growth and the de novo branch start-ups and personnel hires in Roanoke, Virginia and Winston-Salem, North Carolina.

Loans held for sale totaled $1,639,000 at December 31, 2017 and $5,996,000 at December 31, 2016. Loan production volume was $86,612,000 and $78,330,000 for 2017 and 2016, respectively. These loans were approximately 60% purchase, 40% refinancing.

Management of the loan portfolio is organized around portfolio segments. Each segment is comprised of various loan types that are reflective of operational and regulatory reporting requirements. The following table presents the Company's portfolio as of the dates indicated by segment (dollars in thousands): 

Loans

The following table provides loan balance information by geographic regions.  In some circumstances, loans may be originated in one region for borrowers located in other regions (dollars in thousands):

Loans by Geographic Region

	As of December 31, 2017				Percentage Change in Balance Since December 31, 2016
	Balance		Percentage of Portfolio
Danville region	$	230,498	17.2	%	1.4	%
Central region	157,168		11.8		4.5
Southside region	73,217		5.5		(13.3	)
Eastern region	97,978		7.3		12.6
Franklin region	107,853		8.1		(3.0	)
Roanoke region	93,673		7.0		127.7
Alamance region	242,433		18.1		5.2
Guilford region	285,727		21.4		25.3
Winston-Salem region	47,578		3.6		891.4
Total loans	$	1,336,125	100.0	%	14.7	%

The large year over year increases in the Roanoke region and Winston-Salem region were primarily due to the de novo offices and personnel hires in these regions. Management expects continued growth in those markets, but at a reduced velocity. The large year over year increase in the Guilford region was primarily the result of a convergence of improving business conditions in the Greensboro, North Carolina market and an ongoing, active program of customer outreach conducted by the Bank's market area lenders. 

The Danville region consists of offices in Danville, Virginia and Yanceyville, North Carolina. The Central region consists of offices in Bedford, Lynchburg, and the counties of Bedford and Campbell, Virginia. The Southside region consists of offices

44

in Martinsville and Henry County, Virginia. The Eastern region consists of offices in South Boston and the counties of Halifax and Pittsylvania, Virginia. The Franklin region consists of offices in Rocky Mount, Union Hall, and Hardy, Virginia. The Roanoke region consists of an office in Roanoke County, Virginia. The Alamance region consists of offices in Burlington, Graham, and Mebane, North Carolina. The Guilford region consists of offices in Greensboro, North Carolina. The Winston-Salem region consists of an office in Winston-Salem, North Carolina.

The Company does not participate in or have any highly leveraged lending transactions, as defined by bank regulations. The Company has no foreign loans. There were no concentrations of loans to any individual, group of individuals, business, or industry that exceeded 10% of total loans at December 31, 2017 or 2016.

The following table presents the maturity schedule of selected loan types (dollars in thousands):

Maturities of Selected Loan Types

December 31, 2017

	Commercial and Industrial (1)		Construction and Land Development		Total
1 year or less	$	48,156	$	21,328	$	69,484
1 to 5 years (2)	140,022		82,545		222,567
After 5 years (2)	63,488		19,274		82,762
Total	$	251,666	$	123,147	$	374,813

(1) Includes agricultural loans.

(2) Of the loans due after one year, $196,283 have predetermined interest rates and $109,046 have floating or adjustable interest rates.

Provision for Loan Losses

The provision for loan losses was $1,016,000, $250,000, and $950,000 for the years ended December 31, 2017, 2016, and 2015, respectively.

The larger provision for 2017 related to continued loan growth but was mitigated by continued strong asset quality metrics and improving local and national economic indicators. The smaller provision expense in 2016 related to improvement in various qualitative factors, notably asset quality, local economic conditions and continued decline in historical loss factors compared to 2015. Improvements in asset quality were apparent in declines in past due and nonaccrual loans, as well as in qualitative factors for asset quality and economic conditions, which were somewhat offset by additional factors assigned to unseasoned loans in new markets. The provision expense in 2015 related to the increase in organic loan growth and the relatively rapid maturities and renewals of the performing acquired loan portfolio of MainStreet and their resulting transfer to the regular loan portfolio.

Allowance for Loan Losses

The purpose of the ALLL is to provide for probable losses inherent in the loan portfolio. The allowance is increased by the provision for loan losses and by recoveries of previously charged-off loans. Loan charge-offs decrease the allowance.

The ALLL was $13,603,000, $12,801,000, and $12,601,000 at December 31, 2017, 2016, and 2015, respectively. The ALLL as a percentage of loans at each of those dates were 1.02%, 1.10%, and 1.25%, respectively.

The decrease in the allowance as a percentage of loans during 2017 and 2016 was primarily due to continued high asset quality, low charge-offs, and improvement in various qualitative factors, notably economic and legal, used in the determination of the allowance. The allowance as a percentage of loans during 2015 was primarily impacted by the January 2015 acquisition of MainStreet.

In an effort to better evaluate the adequacy of its ALLL, the Company computes its ASC 450, Contingencies, loan balance by reducing total loans by acquired loans and loans that were evaluated for impairment individually or smaller balance nonaccrual loans evaluated for impairment in homogeneous pools. It also adjusts its ASC 450 loan loss reserve balance total by removing allowances associated with these other pools of loans.

The general allowance, ASC 450 (FAS 5) reserves to ASC 450 loans, was 1.04% at December 31, 2017, compared to 1.17% at December 31, 2016. On a dollar basis, the reserve was $13,151,000 at December 31, 2017, compared to $12,429,000 at December 31, 2016. The percentage of the reserve to total loans has declined due to improving local and national economic

45

conditions and continued improvement in asset quality metrics. This segment of the allowance represents by far the largest portion of the loan portfolio and the largest aggregate risk.

The specific allowance, ASC 310-40 (FAS 114) reserves to ASC 310-40 loans, was 5.18% at December 31, 2017, compared to 0.47% at December 31, 2016. On a dollar basis, the reserve was $167,000 at December 31, 2017, compared to $23,000 at December 31, 2016. The increase in the dollar amount of the reserve was related to changes in characteristics of loans reviewed individually for impairment. There is ongoing turnover in the composition of the impaired loan population, which decreased $1,627,000 from December 31, 2016.

The specific allowance does not include reserves related to acquired loans with deteriorated credit quality. This reserve was $285,000 at December 31, 2017, compared to $349,000 at December 31, 2016. This is the only portion of the reserve related to acquired loans. Cash flow expectations for these loans are reviewed on a quarterly basis and unfavorable changes in those estimates relative to the initial estimates can result in the need for specific loan loss provision.

Nonperforming Assets (Loans and Other Real Estate Owned)

Nonperforming loans include loans on which interest is no longer accrued and accruing loans that are contractually past due 90 days or more. Nonperforming loans include loans originated and loans acquired.

Nonperforming loans to total loans were 0.19% at December 31, 2017 compared to 0.30% at December 31, 2016. The decrease in nonperforming loans during 2017 was $992,000.

Nonperforming assets include nonperforming loans and foreclosed real estate. Nonperforming assets represented 0.21% at December 31, 2017 compared to 0.29% of total assets at December 31, 2016.

In most cases, it is the policy of the Company that any loan that becomes 90 days past due will automatically be placed on nonaccrual loan status, accrued interest reversed out of income, and further interest accrual ceased. Any payments received on such loans will be credited to principal. In some cases a loan in process of renewal may become 90 days past due. In these instances the loan may still be accruing because of a delayed renewal process in which the customer has not been billed. In accounting for acquired impaired loans, such loans are not classified as nonaccrual when they become 90 days past due. They are considered to be accruing because their interest income relates to the accretable yield and not to contractual interest payments.

Loans will only be restored to full accrual status after six consecutive months of payments that were each less than 30 days delinquent. The Company strictly adheres with this policy before restoring a loan to normal accrual status.

Impaired Loans

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. The following table shows loans that were considered impaired, exclusive of acquired impaired loans, as of the dates indicated (dollars in thousands):

Troubled Debt Restructurings ("TDRs")

TDRs exist whenever the Company makes a concession to a customer based on the customer's financial distress that would not have otherwise been made in the normal course of business.

There were $1,306,000 in TDRs at December 31, 2017 compared to $2,670,000 at December 31, 2016.

Other Real Estate Owned

Other real estate owned is carried on the consolidated balance sheets at $1,225,000 and $1,328,000 as of December 31, 2017 and 2016, respectively. Foreclosed assets are initially recorded at fair value, less estimated costs to sell, at the date of foreclosure. Loan losses resulting from foreclosure are charged against the ALLL at that time. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of the new cost basis or fair value, less estimated costs to sell with any additional write-downs charged against earnings. For significant assets, these valuations are

typically outside annual appraisals. The following table shows OREO as of the dates indicated (dollars in thousands):

Deposits

The Company's deposits consist primarily of checking, money market, savings, and consumer and commercial time deposits. Average deposits increased $153,139,000, or 11.8%, in 2017, after increasing $68,844,000, or 5.6%, in 2016. Although deposit growth was widespread, a large part of the increase in 2017 was due to the de novo offices and personnel hires in Roanoke, Virginia and Winston-Salem, North Carolina. This growth is mostly in non-maturity, core deposits, the heart of the Company's balance sheet.

Period-end total deposits increased $164,086,000, or 12.0%, during 2017. The increase was primarily related to steady growth in core deposits, which is consistent with the Company's asset liability strategy. The Company has only a relatively small portion of its time deposits provided by wholesale sources. These include brokered time deposits, of which there were none at year end 2017, 2016, and 2015, and time deposits through the CDARS program, which at year end totaled $25,838,000 for 2017, $23,445,000 for 2016, and $23,633,000 for 2015. Management considers the CDARS deposits the functional, though not regulatory, equivalent of core deposits, because they relate to balances derived from customers with long standing relationships with the Company.

Borrowed Funds

In addition to internal deposit generation, the Company also relies on borrowed funds as a supplemental source of funding. Borrowed funds consist of customer repurchase agreements, overnight borrowings from the FHLB and longer-term FHLB advances, and trust preferred capital notes. Customer repurchase agreements are borrowings collateralized by securities of the U.S. Government, its agencies, or Government Sponsored Enterprises ("GSEs") and generally mature daily. The Company considers these accounts to be a stable and low cost source of funds. The securities underlying these agreements remain under the Company's control. Refer to Notes 10 and 11 of the Consolidated Financial Statements contained in Item 8 of this Form 10-K for a discussion of long-term debt.

The following table presents information pertaining to the Company's short-term borrowed funds as of the dates indicated (dollars in thousands):

Short-Term Borrowings

	As of December 31,
	2017			2016
Customer repurchase agreements	$	10,726		$	39,166

In the regular course of conducting its business, the Company takes deposits from political subdivisions of the states of Virginia and North Carolina. At December 31, 2017, the Bank's public deposits totaled $265,543,000. The Company is legally required to provide collateral to secure the deposits that exceed the insurance coverage provided by the FDIC. This collateral can be provided in the form of certain types of government agency bonds or letters of credit from the FHLB. At year-end 2017, the Company had $190,000,000 in letters of credit with the FHLB outstanding to supplement collateral for such deposits.

Shareholders' Equity

The Company's goal with capital management is to be classified as "well capitalized" under regulatory capital ratios and to support growth, while generating acceptable returns on equity and paying a high rate of dividends.

Shareholders' equity was $208,717,000 at December 31, 2017 and $201,380,000 at December 31, 2016.

The Company declared and paid quarterly dividends totaling $0.97 per share for 2017, $0.96 per share for 2016, and $0.93 per share for 2015. Cash dividends in 2017 totaled $8,384,000 and represented a 55.0% payout of 2017 net income, compared to a 50.7% payout in 2016, and a 53.6% payout in 2015.

50

In July 2013, the FRB and OCC issued final rules that make technical changes to its capital rules to align them with the Basel III regulatory capital framework and meet certain requirements of the Dodd-Frank Act. The final rules maintain the general structure of the prompt corrective action framework in effect at such time while incorporating certain increased minimum requirements. Effective January 1, 2015, the final rules require the Company and the Bank to comply with the following minimum capital ratios: (i) a new common equity Tier 1 capital ratio of 4.5% of risk-weighted assets; (ii) a Tier 1 capital ratio of 6.0% of risk-weighted assets (increased from the prior requirement of 4.0%); (iii) a total capital ratio of 8.0% of risk-weighted assets (unchanged from the prior requirement); and (iv) a leverage ratio of 4.0% of total assets (unchanged from the prior requirement). These are the initial capital requirements, which will be phased-in over a four-year period. When fully phased-in on January 1, 2019, the rules will require the Company and the Bank to maintain such minimum ratios plus a 2.5% "capital conservation buffer" (other than for the leverage ratio). The phase-in of the capital conservation buffer requirement began on January 1, 2016, at 0.625% of risk-weighted assets, increasing by the same amount each year until fully implemented at 2.5% on January 1, 2019. Management believes the Company and the Bank will be compliant with the fully phased-in requirements when they become effective January 1, 2019.

The following table represents the major regulatory capital ratios for the Company as of the dates indicated:

	As of December 31,
	2017		2016		2015		2014		2013
Risk-Based Capital Ratios:
Common equity tier 1 capital ratio	11.50	%	11.77	%	12.88	%	NA		NA
Tier 1 capital ratio	13.42	%	13.83	%	15.23	%	16.59	%	16.88	%
Total capital ratio	14.39	%	14.81	%	16.34	%	17.86	%	18.14	%
Leverage Capital Ratios:
Tier 1 leverage ratio	10.95	%	11.67	%	12.05	%	12.16	%	11.81	%

Management believes the Company and the Bank meet the requirements to be considered "well capitalized" for all regulatory capital ratios as of December 31, 2017 and 2016.

Stock Repurchase Programs

On November 19, 2015, the Company filed a Form 8-K with the SEC to announce the approval by its Board of a stock repurchase program. The program authorized the repurchase of up to 300,000 shares of the Company's common stock over a two year period. The share purchase limit was established at such number of shares equal to approximately 3.5% of the 8,622,000 common shares then outstanding at the time the Board approved the program. The program expired on November 19, 2017.

The Company did not repurchase any shares during 2017. During 2016, the Company repurchased 51,384 shares at an average cost of $25.14 per share, for a total cost of $1,292,000.

On January 19, 2018, the Company filed a Form 8-K with the SEC to announce the approval by its Board of another stock repurchase program. The program authorizes the repurchase of up to 300,000 shares of the Company's common stock over a two year period.

OFF-BALANCE SHEET ACTIVITIES

The Company enters into certain financial transactions in the ordinary course of performing traditional banking services that result in off-balance sheet transactions. Other than AMNB Statutory Trust I, formed in 2006 to issue trust preferred securities, and the MidCarolina Trust I and MidCarolina Trust II, the Company does not have any off-balance sheet subsidiaries. Refer to Note 11 of the Consolidated Financial Statements contained in Item 8 of this Form 10-K for a discussion of junior subordinated debt. Off-balance sheet transactions were as follows as of the dates indicated (dollars in thousands):

	December 31,
Off-Balance Sheet Commitments	2017		2016
Commitments to extend credit	$	341,760	$	345,803
Standby letters of credit	13,647		4,088
Mortgage loan rate-lock commitments	5,089		12,839

Commitments to extend credit to customers represent legally binding agreements with fixed expiration dates or other termination clauses. Since many of the commitments are expected to expire without being funded, the total commitment amounts do not necessarily represent future funding requirements. Standby letters of credit are conditional commitments issued by the Company guaranteeing the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders

American National Bankshares Inc.

Danville, Virginia

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of American National Bankshares Inc. and Subsidiary (the Company) as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, changes in shareholders' equity and cash flows for each of the three years in the period ended December 31, 2017, and the related notes to the consolidated financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated March 9, 2018 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders

American National Bankshares Inc.

Danville, Virginia

Opinion on the Internal Control over Financial Reporting

We have audited American National Bankshares Inc. and Subsidiary’s (the Company) internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, changes in shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2017, and the related notes to the consolidated financial statements of the Company and our report dated March 9, 2018 expressed an unqualified opinion.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

55

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

American National Bankshares Inc.

Notes to Consolidated Financial Statements

December 31, 2017, 2016, and 2015

Note 1 – Summary of Significant Accounting Policies

Nature of Operations and Consolidation

The consolidated financial statements include the accounts of American National Bankshares Inc. (the "Company") and its wholly owned subsidiary, American National Bank and Trust Company (the "Bank").  The Bank offers a wide variety of retail, commercial, secondary market mortgage lending, and trust and investment services which also include non-deposit products such as mutual funds and insurance policies.

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, goodwill and intangible assets, unfunded pension liability, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, the valuation of other real estate owned ("OREO"), and the valuation of deferred tax assets and liabilities.

In April 2006, AMNB Statutory Trust I, a Delaware statutory trust (the "AMNB Trust") and an unconsolidated wholly owned subsidiary of the Company, was formed for the purpose of issuing preferred securities (the "Trust Preferred Securities") in a private placement pursuant to an applicable exemption from registration.  Proceeds from the securities were used to fund the acquisition of Community First Financial Corporation ("Community First") which occurred in April 2006.

On July 1, 2011, the Company completed its acquisition of MidCarolina Financial Corporation ("MidCarolina") pursuant to the terms and conditions of the Agreement and Plan of Reorganization, dated December 15, 2010, between the Company and MidCarolina.  MidCarolina was headquartered in Burlington, North Carolina, and engaged in banking operations through its subsidiary bank, MidCarolina Bank.  The transaction has expanded the Company's footprint in North Carolina, adding eight branches in Alamance and Guilford Counties.

In July 2011, and in connection with its acquisition of MidCarolina, the Company assumed liabilities of the MidCarolina Trust I and MidCarolina Trust II, two separate unconsolidated Delaware statutory trusts (the "MidCarolina Trusts"), which were also formed for the purpose of issuing preferred securities.  Refer to Note 11 for further details concerning these entities.

On January 1, 2015, the Company completed its acquisition of MainStreet BankShares, Inc. ("MainStreet") pursuant to the terms and conditions of the Agreement and Plan of Reorganization, dated as of August 24, 2014, between the Company and MainStreet (the "MainStreet Merger Agreement"). Immediately after the merger of MainStreet into the Company, Franklin Community Bank, N.A., MainStreet's wholly-owned bank subsidiary ("Franklin Bank"), merged with and into the Bank. Franklin Bank provided banking services to its customers from three banking offices located in Rocky Mount, Hardy, and Union Hall, Virginia.

All significant inter-company transactions and accounts are eliminated in consolidation, with the exception of the AMNB Trust and the MidCarolina Trusts, as detailed in Note 11.

Cash and Cash Equivalents

Cash includes cash on hand, cash with correspondent banks, and cash on deposit at the Federal Reserve Bank of Richmond.  Cash equivalents are short-term, highly liquid investments that are readily convertible to cash with original maturities of three months or less and are subject to an insignificant risk of change in value.  Cash and cash equivalents are carried at cost.

Interest-bearing Deposits in Other Banks

Interest-bearing deposits in other banks mature within one year and are carried at cost.

Securities

Certain debt securities that management has the positive intent and ability to hold to maturity are classified as "held to maturity" and recorded at amortized cost. Trading securities are recorded at fair value with changes in fair value included in

62

earnings. Securities not classified as held to maturity or trading, including equity securities with readily determinable fair values, are classified as "available for sale" and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.

The Company does not currently have any securities in held to maturity or trading and has no plans to add any to either category. Management evaluates securities for other-than-temporary impairment ("OTTI") on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement and, (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.

Due to the nature and restrictions placed on the Company's investment in common stock of the Federal Home Loan Bank of Atlanta ("FHLB") and the Federal Reserve Bank of Richmond, these securities have been classified as restricted equity securities and carried at cost.

Loans Held for Sale

Secondary market mortgage loans are designated as held for sale at the time of their origination.  These loans are pre-sold with servicing released and the Company does not retain any interest after the loans are sold.  These loans consist primarily of fixed-rate, single-family residential mortgage loans which meet the underwriting characteristics of certain government-sponsored enterprises (conforming loans).  In addition, the Company requires a firm purchase commitment from a permanent investor before a loan can be committed, thus limiting interest rate risk.  Loans held for sale are carried at fair value.  Gains on sales of loans are recognized at the loan closing date and are included in noninterest income.

Derivative Loan Commitments

The Company enters into mortgage loan commitments whereby the interest rate on the loan is determined prior to funding (rate lock commitments).  Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding.  Loan commitments that are derivatives are recognized at fair value on the consolidated balance sheets with net changes in their fair values recorded in other expenses.  Derivative loan commitments resulted in no income or loss for 2017, 2016 or 2015.

The period of time between issuance of a loan commitment and sale of the loan generally ranges from 30 to 60 days. The Company protects itself from changes in interest rates through the use of best efforts forward delivery contracts, by committing to sell a loan at the time the borrower commits to an interest rate with the intent that the buyer has assumed the interest rate risk on the loan.  As a result, the Company is not generally exposed to significant losses nor will it realize significant gains related to its rate lock commitments due to changes in interest rates.  The correlation between the rate lock commitments and the best efforts contracts is very high due to their similarity.

The fair value of rate lock commitments and best efforts contracts is not readily ascertainable with precision because rate lock commitments and best efforts contracts are not actively traded in stand-alone markets.  The Company determines the fair value of rate lock commitments and best efforts contracts by measuring the change in the estimated value of the underlying assets while taking into consideration the probability that the loan will be funded.

Loans

The Company makes mortgage, commercial, and consumer loans.  A substantial portion of the loan portfolio is secured by real estate.  The ability of the Company's debtors to honor their contracts is dependent upon the real estate market and general economic conditions in the Company's market area.

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off, generally are reported at their outstanding unpaid principal balance adjusted for the allowance for loan losses, and any deferred fees or costs.  Interest income is accrued on the unpaid principal balance.  Loan origination fees, net of certain direct origination costs,

63

are deferred and recognized as an adjustment of the related loan yield using the interest method. The accrual of interest on loans is generally discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection.  Loans are typically charged off when the loan is 120 days past due, unless secured and in process of collection.  Loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful.

Interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income.  The interest on these loans is accounted for on the cash basis or cost recovery method, until qualifying for return to accrual status.  Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

A loan is considered past due when a payment of principal or interest or both is due but not paid.  Management closely monitors past due loans in timeframes of 30-59 days, 60-89 days, and 90 or more days past due.

These policies apply to all loan portfolio classes and segments.

Substandard and doubtful risk graded commercial, commercial real estate, and construction loans equal to or greater than $100,000 are reviewed for impairment. All troubled debt restructurings, regardless of dollar amount, are also evaluated for impairment. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement.  Factors considered by management in determining impairment and establishing a specific allowance include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due.  Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed.  Impairment is measured on a loan-by-loan basis for commercial, commercial real estate, and construction loans by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

Generally, large groups of smaller balance homogeneous loans (residential real estate and consumer loans) are collectively evaluated for impairment.  The Company's policy for recognizing interest income on impaired loans is consistent with its nonaccrual policy.

The Company's loan portfolio is organized by major segment. These include: commercial, commercial real estate, residential real estate and consumer loans.  Each segment has particular risk characteristics that are specific to the borrower and the generic category of credit.  Commercial loan repayments are highly dependent on cash flows associated with the underlying business and its profitability.  They can also be impacted by changes in collateral values.  Commercial real estate loans share the same general risk characteristics as commercial loans, but are often more dependent on the value of the underlying real estate collateral and, when construction is involved, the ultimate completion of and sale of the project.  Residential real estate loans are generally dependent on the value of collateral and the credit worthiness of the underlying borrower.  Consumer loans are very similar in risk characteristics to residential real estate.

In connection with the MidCarolina and MainStreet mergers, certain loans were acquired which exhibited deteriorated credit quality since origination and for which the Company does not expect to collect all contractual payments.  These purchased credit impaired loans are recorded at the amount paid, such that there is no carryover of the seller's allowance for loan losses.  After acquisition, losses are recognized by an increase in the allowance for loan losses.

Such purchased credit impaired loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as, credit score, loan type, and date of origination.  The Company estimates the amount and timing of expected cash flows for each loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield).  The excess of the loan's or pool's contractual principal and interest over expected cash flows is not recorded (nonaccretable difference).

Over the life of the loan or pool, expected cash flows continue to be estimated.  If the present value of expected cash flows is less than the carrying amount, a loss is recorded as a provision for loan losses.  If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income.

Troubled Debt Restructurings

In situations where, for economic or legal reasons related to a borrower's financial condition, management may grant a concession to the borrower that it would not otherwise consider, the related loan is classified as a troubled debt restructuring

64

("TDRs").  Management strives to identify borrowers in financial difficulty early and work with them to modify their loan to more affordable terms before their loan reaches nonaccrual status.  These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral.  In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans.  The Company has $1,306,000 in loans classified as TDRs as of December 31, 2017 and $2,670,000 as of December 31, 2016.

Allowance for Loan Losses

The purpose of the allowance for loan losses ("ALLL") is to provide for probable losses inherent in the loan portfolio.  The allowance is increased by the provision for loan losses and by recoveries of previously charged-off loans.  Loan charge-offs decrease the allowance.

The goal of the Company is to maintain an appropriate, systematic, and consistently applied process to determine the amounts of the ALLL and the provision for loan loss expense.

The Company uses certain practices to manage its credit risk.  These practices include (1) appropriate lending limits for loan officers, (2) a loan approval process, (3) careful underwriting of loan requests, including analysis of borrowers, cash flows, collateral, and market risks, (4) regular monitoring of the portfolio, including diversification by type and geography, (5) review of loans by the Loan Review department, which operates independently of loan production (the Loan Review function consists of a co-sourced arrangement using both internal personnel and external vendors to provide the Company with a more robust review function of the loan portfolio), (6) regular meetings of the Credit Committees to discuss portfolio and policy changes and make decisions on large or unusual loan requests, and (7) regular meetings of the Asset Quality Committee which reviews the status of individual loans.

Risk grades are assigned as part of the loan origination process. From time to time risk grades may be modified as warranted by the facts and circumstances surrounding the credit.

Calculation and analysis of the allowance for loan losses is prepared quarterly by the Finance Department.  The Company's Credit Committee, Capital Management Committee, Audit Committee, and the Board of Directors review the allowance for adequacy.

The Company's allowance for loan losses has two basic components:  the formula allowance and the specific allowance.  Each of these components is determined based upon estimates and judgments.

The formula allowance uses historical loss experience as an indicator of future losses, along with various qualitative factors, including levels and trends in delinquencies, nonaccrual loans, charge-offs and recoveries, trends in volume and terms of loans, effects of changes in underwriting standards, experience of lending staff, economic conditions, and portfolio concentrations. In the formula allowance for commercial and commercial real estate loans, the historical loss rate is combined with the qualitative factors, resulting in an adjusted loss factor for each risk-grade category of loans.  The period-end balances for each loan risk-grade category are multiplied by the adjusted loss factor.  Allowance calculations for consumer loans are calculated based on historical losses for each product category without regard to risk grade. This loss rate is combined with qualitative factors resulting in an adjusted loss factor for each product category.

The specific allowance uses various techniques to arrive at an estimate of loss for specifically identified impaired loans. These include:

• The present value of expected future cash flows discounted at the loan's effective interest rate.  The effective interest rate on a loan is the rate of return implicit in the loan (that is, the contractual interest rate adjusted for any net deferred loan fees or costs and any premium or discount existing at the origination or acquisition of the loan);

• The loan's observable market price, or

• The fair value of the collateral, net of estimated costs to dispose, if the loan is collateral dependent.

The use of these computed values is inherently subjective and actual losses could be greater or less than the estimates. No single statistic, formula, or measurement determines the adequacy of the allowance.  Management makes subjective and complex judgments about matters that are inherently uncertain, and different amounts would be reported under different conditions or using different assumptions.  For analytical purposes, management allocates a portion of the allowance to specific loan categories and specific loans.  However, the entire allowance is used to absorb credit losses inherent in the loan portfolio, including identified and unidentified losses.

The relationships and ratios used in calculating the allowance, including the qualitative factors, may change from period to period as facts and circumstances evolve.  Furthermore, management cannot provide assurance that in any particular period the

65

Company will not have sizeable credit losses in relation to the amount reserved.  Management may find it necessary to significantly adjust the allowance, considering current factors at the time.

Premises and Equipment

Land is carried at cost.  Premises and equipment are stated at cost, less accumulated depreciation and amortization.  Premises and equipment are depreciated over their estimated useful lives ranging from three years to thirty-nine years; leasehold improvements are amortized over the lives of the respective leases or the estimated useful lives of the improvements, whichever is less.  Software is generally amortized over three years.  Depreciation and amortization are recorded on the straight-line method.

Costs of maintenance and repairs are charged to expense as incurred.  Costs of replacing structural parts of major units are considered individually and are expensed or capitalized as the facts dictate.  Gains and losses on routine dispositions are reflected in current operations.

Goodwill and Intangible Assets

Goodwill is subject to at least an annual assessment for impairment by applying a fair value based test.  Additionally, acquired intangible assets (such as core deposit intangibles) are separately recognized if the benefit of the assets can be sold, transferred, licensed, rented, or exchanged, and amortized over their useful lives.  Intangible assets related to branch transactions continued to amortize. The cost of purchased deposit relationships and other intangible assets, based on independent valuation, are being amortized over their estimated lives ranging from eight to ten years.

The Company records as goodwill the excess of purchase price over the fair value of the identifiable net assets acquired. Impairment testing is performed annually, as well as when an event triggering impairment may have occurred. The Company performs its annual analysis as of June 30 each fiscal year. Accounting guidance permits preliminary assessment of qualitative factors to determine whether more substantial impairment testing is required. The Company chose to bypass the preliminary assessment and utilized a two-step process for impairment testing of goodwill. The first step tests for impairment, while the second step, if necessary, measures the impairment.  No indicators of impairment were identified during the years ended December 31, 2017, 2016, or 2015.

Trust Assets

Securities and other property held by the trust and investment services segment in a fiduciary or agency capacity are not assets of the Company and are not included in the accompanying consolidated financial statements.

Other Real Estate Owned

Other real estate owned represents real estate that has been acquired through loan foreclosures or deeds received in lieu of loan payments. Generally, such properties are appraised at the time acquired, and are recorded at fair value less estimated selling costs.  Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in noninterest expense.

Bank Owned Life Insurance

The Company has acquired bank owned life insurance ("BOLI") in connection with three acquisitions. The asset is reflected as the cash surrender value of the policies as provided by the insurer on a monthly basis.

Transfers of Financial Assets

Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company – put presumptively beyond reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.

Income Taxes

The Company uses the balance sheet method to account for deferred income tax assets and liabilities.  Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws.

66

When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained.  The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any.  Tax positions taken are not offset or aggregated with other positions.  Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority.  The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination.  The Company had no liability for unrecognized tax benefits as of December 31, 2017 and 2016.

Stock-Based Compensation

Stock compensation accounting guidance Accounting Standards Codification ("ASC") 718, "Compensation – Stock Compensation" requires that the compensation cost relating to share-based payment transactions be recognized in financial statements.  That cost will be measured based on the grant date fair value of the equity or liability instruments issued.  The stock compensation accounting guidance covers a wide range of share-based compensation arrangements including stock options, restricted share plans, performance-based awards, share appreciation rights, and employee share purchase plans.

The stock compensation accounting guidance requires that compensation cost for all stock awards be calculated and recognized over the employees' service period, generally defined as the vesting period.  For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.  A Black-Scholes model is used to estimate the fair value of stock options, while the market price of the Company's common stock at the date of grant is used for restricted stock awards.

Earnings Per Common Share

Basic earnings per common share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share reflect the impact of additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company consist solely of outstanding stock options, and are determined using the treasury method. Nonvested shares of restricted stock are included in the computation of basic earnings per share because the holder has voting rights and shares in non-forfeitable dividends during the vesting period.

Comprehensive Income

Comprehensive income is shown in a two statement approach; the first statement presents total net income and its components followed by a second statement that presents all the components of other comprehensive income such as unrealized gains and losses on available for sale securities and changes in the funded status of a defined benefit postretirement plan.

In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”).  The Company early adopted this new standard in early 2018. ASU 2018-02 requires reclassification from AOCI to retained earnings for "stranded" tax effects resulting from the impact of the newly enacted federal corporate income tax rate on items included in AOCI.  The amount of this reclassification in 2017 was $545,000 and is reflected in the Consolidated Statements of Changes in Shareholders' equity.

Advertising and Marketing Costs

Advertising and marketing costs are expensed as incurred, and were $352,000, $260,000, and $356,000 in 2017, 2016, and 2015, respectively.

Mergers and Acquisitions

Business combinations are accounted for under ASC 805, "Business Combinations", using the acquisition method of accounting. The acquisition method of accounting requires an acquirer to recognize the assets acquired and the liabilities assumed at the acquisition date measured at their fair values as of that date. To determine the fair values, the Company relies on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Under the acquisition method of accounting, the Company identifies the acquirer and the closing date and applies

67

applicable recognition principles and conditions. Acquisition-related costs are costs the Company incurs to effect a business combination. Those costs include advisory, legal, accounting, valuation, and other professional or consulting fees. Some other examples of costs to the Company include systems conversions, integration planning consultants and advertising costs. The Company accounts for acquisition-related costs as expenses in the periods in which the costs are incurred and the services are received, with one exception. The costs to issue debt or equity securities is recognized in accordance with other applicable GAAP. These acquisition-related costs have been and will be included within the Consolidated Statements of Income classified within the noninterest expense caption.

Reclassifications

Certain reclassifications have been made in prior years financial statements to conform to classifications used in the current year. There were no material reclassifications.

Use of Estimates

In preparing consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, goodwill and intangible assets, unfunded pension liability, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, the valuation of other real estate owned, and the valuation of deferred tax assets and liabilities.

Adoption of New Accounting Standards

During the first quarter of 2017, the Company adopted ASU No. 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employer Share-Based Payment Accounting."This ASU simplifies several aspects of the accounting for share-based payment award transactions, one of which is the recognition of excess tax benefits and deficiencies related to share-based payments, including tax benefits of dividends on share-based payment awards. Prior to the adoption of ASU 2016-09, such tax consequences were recognized as components of additional paid-in capital. With the adoption of this ASU, tax benefits and deficiencies are recognized within income tax expense. In accordance with the adoption provisions of ASU 2016-09, the results for 2016 and 2015 include only the excess tax (expense) benefits attributable to 2016 and 2015 in the amounts of $17,000 and $13,000, respectively.

During February 2018, the FASB issued ASU No. 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This ASU provides financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (the "Tax Reform Act"), or portion thereof, is recorded. The amendments are effective for all organizations for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. Organizations should apply the proposed amendments either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Reform Act is recognized. The Company has elected to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act of $545,000 in its consolidated financial statements for the period ended December 31, 2017.

Recent Accounting Pronouncements

In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The amendments in ASU 2016-01, among other things: (1) requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (2) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (3) Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables); and (4) eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not expect the adoption of ASU 2016-01 to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the

68

commencement date: (1) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company has analyzed all leases currently in place and determined the adoption of ASU 2016-02 will not have a material impact on its consolidated financial statements.

During June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The amendments in this ASU are effective for Securities and Exchange Commission ("SEC") filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company has formed a committee to address the adoption of the standard and engaged a third party vendor to assist with the data gathering and analysis. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements.

During August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments", to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The amendments should be applied using a retrospective transition method to each period presented. If retrospective application is impractical for some of the issues addressed by the update, the amendments for those issues would be applied prospectively as of the earliest date practicable.Early adoption is permitted, including adoption in an interim period. The Company does not expect the adoption of ASU 2016-15 to have a material impact on its consolidated financial statements.

During January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business". The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the current implementation guidance in Topic 805, there are three elements of a business - inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a "set") that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this ASU provide a screen to determine when a set is not a business. If the screen is not met, the amendments (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The ASU provides a framework to assist entities in evaluating whether both an input and a substantive process are present. The amendments in this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The amendments in this ASU should be applied prospectively on or after the effective date. No disclosures are required at transition. The Company does not expect the adoption of ASU 2017-01 to have a material impact on its consolidated financial statements.

During January 2017, the FASB issued ASU No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of ASU 2017-04 to have a material impact on its consolidated financial statements.

69

During March 2017, the FASB issued ASU No. 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The amendments in this ASU require an employer that offers defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715 to report the service cost component of net periodic benefit cost in the same line item(s) as other compensation costs arising from services rendered during the period. The other components of net periodic benefit cost are required to be presented in the income statement separately from the service cost component. If the other components of net periodic benefit cost are not presented on a separate line or lines, the line item(s) used in the income statement must be disclosed. In addition, only the service cost component will be eligible for capitalization as part of an asset, when applicable. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted. The Company does not expect the adoption of ASU 2017-07 to have a material impact on its consolidated financial statements.

During March 2017, the FASB issued ASU No. 2017-08, “Receivables-Nonrefundable Fees and Other Costs (Subtopic 310‐20), Premium Amortization on Purchased Callable Debt Securities.” The amendments in this ASU shorten the amortization period for certain callable debt securities purchased at a premium. Upon adoption of the standard, premiums on these qualifying callable debt securities will be amortized to the earliest call date. Discounts on purchased debt securities will continue to be accreted to maturity. The amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Upon transition, entities should apply the guidance on a modified retrospective basis, with a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption and provide the disclosures required for a change in accounting principle. The Company is currently assessing the impact that ASU 2017-08 will have on its consolidated financial statements.

During May 2017, the FASB issued ASU No. 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting.” The amendments provide guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718.  The amendments are effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued. The Company is currently assessing the impact that ASU 2017-09 will have on its consolidated financial statements.

During August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” The amendments in this ASU modify the designation and measurement guidance for hedge accounting as well as provide for increased transparency regarding the presentation of economic results on both the financial statements and related footnotes. Certain aspects of hedge effectiveness assessments will also be simplified upon implementation of this update. The amendments are effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period. The Company does not expect the adoption of ASU 2017-12 to have a material impact on its consolidated financial statements.

Note 2 – Restrictions on Cash

The Company is a member of the Federal Reserve System and is required to maintain certain levels of its cash and cash equivalents as reserves based on regulatory requirements. The gross reserve requirement with the Federal Reserve Bank of Richmond was $2.8 million and $2.3 million at December 31, 2017 and December 31, 2016, respectively. Due to vault cash that exceeded the gross reserve requirement, the balance to be maintained with the Federal Reserve Bank of Richmond was zero at both year ends.

The Company maintains cash accounts in other commercial banks.  The amount on deposit with correspondent institutions at December 31, 2017 exceeded the insurance limits of the Federal Deposit Insurance Corporation by $239,000.

The amortized cost and estimated fair value of investments in securities at December 31, 2017, by contractual maturity, are shown in the following table.  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.  Because mortgage-backed securities have both known principal repayment terms as well as unknown principal repayments due to potential borrower pre-payments, it is difficult to accurately predict the final maturity of these investments.  Mortgage-backed securities are shown separately (dollars in thousands):

	Available for Sale
	Amortized Cost		Fair Value
Due in one year or less	$	11,540	$	11,549
Due after one year through five years	102,806		102,982

letters of credit were used as additional collateral in the amounts of $190,700,000 at December 31, 2017 and $130,700,000 at December 31, 2016.

Temporarily Impaired Securities

The following table shows estimated fair value and gross unrealized losses, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at December 31, 2017.  The reference point for determining when securities are in an unrealized loss position is month-end.  Therefore, it is possible that a security's market value exceeded its amortized cost on other days during the past twelve-month period.

Available for sale securities that have been in a continuous unrealized loss position are as follows (dollars in thousands):

	Total				Less than 12 Months				12 Months or More
	Fair Value		Unrealized Loss		Fair Value		Unrealized Loss		Fair Value		Unrealized Loss
Federal agencies and GSEs	$	99,133	$	2,127	$	45,474	$	321	$	53,659	$	1,806
Mortgage-backed and CMOs	90,806		1,140		64,449		533		26,357		607

Total	$	226,018	$	3,628	$	137,860	$	1,018	$	88,158	$	2,610

Federal agencies and GSEs: The unrealized losses on the Company's investment in 24 government sponsored entities ("GSE") were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2017.

Mortgage-backed securities: The unrealized losses on the Company's investment in 53 GSE mortgage-backed securities were caused by interest rate increases. Sixteen of these securities were in an unrealized loss position for 12 months or more. The contractual cash flows of those investments are guaranteed by an agency of the U.S. Government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost bases of the Company's investments. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2017.

Collateralized Mortgage Obligations: The unrealized loss associated with one private GSE collateralized mortgage obligation ("CMO") is due to normal market fluctuations. This security has been in an unrealized loss position for 12 months or more. The contractual cash flows of those investments are guaranteed by an agency of the U.S. Government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost bases of the Company's investments. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2017.

State and municipal securities:  The unrealized losses on 50 state and municipal securities were caused by interest rate increases and not credit deterioration. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2017.

Corporate securities:  The unrealized losses on two corporate securities were caused by interest rate increases and not credit deterioration. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2017.

Due to restrictions placed upon the Bank's common stock investment in the Federal Reserve Bank of Richmond and FHLB, these securities have been classified as restricted equity securities and carried at cost. These restricted securities are not subject to the investment security classifications and are included as a separate line item on the Company's Consolidated Balance Sheet. The FHLB requires the Bank to maintain stock in an amount equal to 4.25% of outstanding borrowings and a specific percentage of the Bank's total assets. The Federal Reserve Bank of Richmond requires the Bank to maintain stock with a par value equal to 3.0% of its outstanding capital and an additional 3.0% is on call. Restricted equity securities consist of Federal Reserve Bank of Richmond stock in the amount of $3,587,000 and $3,559,000 as of December 31, 2017 and 2016 and FHLB stock in the amount of $2,523,000 and $2,665,000 as of December 31, 2017 and 2016, respectively.

Consumer Credit Exposure

Credit Risk Profile Based on Payment Activity

	Consumer
Performing	$	4,415
Nonperforming	13
Total	$	4,428

Loans classified in the Pass category typically are fundamentally sound and risk factors are reasonable and acceptable.

Loans classified in the Special Mention category typically have been criticized internally, by loan review or the loan officer, or by external regulators under the current credit policy regarding risk grades.

Loans classified in the Substandard category typically have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt; they are typically characterized by the possibility that the Bank will sustain some loss if the deficiencies are not corrected.

Loans classified in the Doubtful category typically have all the weaknesses inherent in loans classified as substandard, plus the added characteristic the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions,

78

and values highly questionable and improbable. However, these loans are not yet rated as loss because certain events may occur that may salvage the debt.

Consumer loans are classified as performing or nonperforming.  A loan is nonperforming when payments of interest and principal are past due 90 days or more, or payments are less than 90 days past due, but there are other good reasons to doubt that payment will be made in full.

Note 7 – Goodwill and Other Intangible Assets

The Company records as goodwill the excess of purchase price over the fair value of the identifiable net assets acquired. Impairment testing is performed annually, as well as when an event triggering impairment may have occurred. The Company performs its annual analysis as of June 30 each fiscal year. Accounting guidance permits preliminary assessment of qualitative factors to determine whether more substantial impairment testing is required. The Company chose to bypass the preliminary assessment and utilized a two-step process for impairment testing of goodwill. The first step tests for impairment, while the second step, if necessary, measures the impairment.  No indicators of impairment were identified during the years ended December 31, 2017, 2016, or 2015.

Core deposit intangibles resulting from the Community First acquisition in April 2006 were $3,112,000 and were amortized over 99 months ending in 2015. Core deposit intangibles resulting from the MidCarolina acquisition in July 2011 were $6,556,000 and are being amortized on an accelerated basis over 108 months. Core deposit intangibles resulting from the MainStreet acquisition were $1,839,000 and are being amortized on an accelerated basis over 120 months.

Note 11 – Junior Subordinated Debt

On April 7, 2006, AMNB Statutory Trust I, a Delaware statutory trust and a wholly owned subsidiary of the Company, issued $20,000,000 of preferred securities in a private placement pursuant to an applicable exemption from registration.  The Trust Preferred Securities mature on June 30, 2036, but may be redeemed at the Company's option beginning on September 30, 2011.  Initially, the securities required quarterly distributions by the trust to the holder of the Trust Preferred Securities at a fixed rate of 6.66%.  Effective September 30, 2011, the rate resets quarterly at the three-month LIBOR plus 1.35%.  Distributions are cumulative and will accrue from the date of original issuance, but may be deferred by the Company from time to time for up to 20 consecutive quarterly periods.  The Company has guaranteed the payment of all required distributions on the Trust Preferred Securities. The proceeds of the Trust Preferred Securities received by the trust, along with proceeds of $619,000 received by the trust from the issuance of common securities by the trust to the Company, were used to purchase $20,619,000 of the Company's junior subordinated debt securities (the "Trust Preferred Capital Notes"), issued pursuant to a junior subordinated debentures entered into between the Company and Wilmington Trust Company, as trustee.  The proceeds of the Trust Preferred Capital Notes were used to fund the cash portion of the merger consideration to the former shareholders of Community First in connection with the Company's acquisition of that company, and for general corporate purposes.

On July 1, 2011, in connection with the MidCarolina merger, the Company assumed $8,764,000 in junior subordinated debentures to the MidCarolina Trusts, to fully and unconditionally guarantee the preferred securities issued by the MidCarolina Trusts. These long-term obligations, which currently qualify as Tier 1 capital, constitute a full and unconditional guarantee by the Company of the MidCarolina Trusts' obligations. The MidCarolina Trusts are not consolidated in the Company's financial statements.

In accordance with ASC 810-10-15-14, "Consolidation – Overall - Scope and Scope Exceptions," the Company did not eliminate through consolidation the Company's $619,000 equity investment in AMNB Statutory Trust I or the $264,000 equity investment in the MidCarolina Trusts.  Instead, the Company reflected this equity investment in the "Accrued interest receivable and other assets" line item in the consolidated balance sheets.

84

A description of the junior subordinated debt securities outstanding payable to the trusts is shown below (dollars in thousands):

				Principal Amount
				As of December 31,
Issuing Entity	DateIssued	InterestRate	MaturityDate	2017		2016
AMNB Trust I	4/7/2006	Libor plus 1.35%	6/30/2036	$	20,619	$	20,619

				$	27,826	$	27,724

The principal amounts reflected for the MidCarolina Trusts as of December 31, 2017 and 2016, are net of fair value marks of $833,000 and $724,000, respectively. The original fair value marks of $1,197,000 and $1,021,000 were recorded as a result of the merger with MidCarolina on July 1, 2011 and are being amortized into interest expense over the remaining lives of the respective borrowings.

Note 12 – Stock-Based Compensation

The Company's 2008 Stock Incentive Plan ("2008 Plan") was adopted by the Board of Directors of the Company on February 19, 2008 and approved by shareholders on April 22, 2008 at the Company's 2008 Annual Meeting of Shareholders.  Until its expiration date on February 18, 2018, the 2008 Plan provided for the granting of restricted stock awards, incentive and non-statutory options to employees and directors on a periodic basis, at the discretion of the Board of Directors or a Board designated committee. The 2008 Plan authorized the issuance of up to 500,000 shares of common stock. The 2008 Plan replaced the Company's stock option plan that was approved by the shareholders at the 1997 Annual Meeting, which terminated in 2006. The 2008 Plan terminated in February 2018. The Board will be proposing a 2018 Equity Compensation Plan for shareholder approval at the upcoming Annual Meeting.

Stock Options

Accounting guidance requires that compensation cost relating to share-based payment transactions be recognized in the financial statements with measurement based upon the fair value of the equity or liability instruments issued.

A summary of stock option transactions for the year ended December 31, 2017 is as follows:

	Option Shares		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value ($000)
Outstanding at December 31, 2016	58,411		$	24.37
Replacement stock options	—		—

Exercisable at December 31, 2017	50,985		$	24.09	0.79 years	$	725

The aggregate intrinsic value of stock options in the table above represents the total pre-tax intrinsic value (the amount by which the current fair value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders had all option holders exercised their options on December 31, 2017.  This amount changes based on changes in the fair value of the Company's common stock.

85

The total proceeds of the in-the-money options exercised during the year ended December 31, 2017, 2016, and 2015 were $113,000, $142,000, and $789,000, respectively.  Total intrinsic value of options exercised during years ended December 31, 2017, 2016, and 2015 was $287,000, $11,000, and $220,000, respectively.

As of December 31, 2017, 2016, and 2015, there was no recognized or unrecognized compensation expense attributable to the outstanding stock options.

The following table summarizes information related to stock options outstanding on December 31, 2017:

$30.01 to $41.67	1,650	0.01	33.33
	50,985	0.79 years	$	24.09

No stock options were granted in 2017, 2016 and 2015.

Restricted Stock

The Company from time-to-time grants shares of restricted stock to key employees and non-employee directors.  These awards help align the interests of these employees and directors with the interests of the shareholders of the Company by providing economic value directly related to increases in the value of the Company's common stock.  The value of the stock awarded is established as the fair market value of the stock at the time of the grant.  The Company recognizes expense, equal to the total value of such awards, ratably over the vesting period of the stock grants. Restricted stock granted in 2017 cliff vests at the end of a 36-month period beginning on the date of grant. Nonvested restricted stock activity for the year ended December 31, 2017 is summarized in the following table:

Restricted Stock	Shares		Weighted Average Grant Date Value
Nonvested at December 31, 2016	50,822		$	23.21
Granted	14,453		34.74
Vested	(18,774	)	24.49
Forfeited	—		—
Nonvested at December 31, 2017	46,501		26.28

As of December 31, 2017, 2016, and 2015, there was $538,000, $568,000, and $340,000, respectively, in unrecognized compensation cost related to nonvested restricted stock granted under the 2008 Plan.  This cost is expected to be recognized over the next 12 to 36 months.  The share based compensation expense for nonvested restricted stock was $532,000, $444,000, and $322,000 during 2017, 2016, and 2015, respectively.

Starting in 2010, the Company began offering its outside directors alternatives with respect to director compensation. The regular monthly board retainer can be received quarterly in the form of either (i) $5,800 in cash or (ii) shares of immediately vested, but restricted stock, with a market value of $6,250. Monthly meeting fees can also be received as $725 per meeting in cash or $900 in immediately vested, but restricted stock.  For 2017, 11 of the 13 outside directors elected to receive stock in lieu of cash for either all of part of their retainer or meeting fees. Only outside directors receive board fees. The Company issued 13,093, 13,166 and 11,228 shares and recognized share based compensation expense of $484,000, $380,000, and $275,000 during 2017, 2016 and 2015, respectively.

During 2015, 4,158 shares with a market value of $95,000 were issued to a retired director as payment for cumulative deferred director compensation.

Note 14 – Earnings Per Common Share

The following shows the weighted average number of shares used in computing earnings per common share and the effect on weighted average number of shares of potentially dilutive common stock.  Potentially dilutive common stock had no effect on income available to common shareholders. Nonvested restricted shares are included in the computation of basic earnings per share as the holder is entitled to full shareholder benefits during the vesting period including voting rights and sharing in nonforfeitable dividends.

	Years Ended December 31,
	2017			2016			2015
	Shares	Per Share Amount		Shares	Per Share Amount		Shares	Per Share Amount
Basic earnings per share	8,641,717	$	1.76	8,611,507	$	1.89	8,680,502	$	1.73

Outstanding stock options on common stock which were not included in computing diluted earnings per share in 2017, 2016, and 2015 because their effects were anti-dilutive, averaged 330 shares, 11,397 shares, and 66,238 shares, respectively.

Note 15 – Off-Balance Sheet Activities

The Company is party to credit-related financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers.  These financial instruments include commitments to extend credit and standby letters of credit.  Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets.  The Company evaluates each customer's credit worthiness on a case-by-case basis.  The amount of collateral obtained, if applicable, is based on management's credit evaluation of the customer.

The Company's exposure to credit loss is represented by the contractual amount of these commitments.  The Company follows the same credit policies in making commitments as it does for on-balance sheet instruments.

The following off-balance sheet financial instruments whose contract amounts represent credit risk were outstanding at December 31, 2017 and 2016 (dollars in thousands):

	December 31,
	2017		2016
Commitments to extend credit	$	341,760	$	345,803
Standby letters of credit	13,647		4,088
Mortgage loan rate lock commitments	5,089		12,839

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. These commitments generally consist of unused portions of lines of credit issued to customers. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee.  Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party.  Those letters of credit are primarily issued to support public and private borrowing arrangements.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers.

At December 31, 2017, the Company had locked-rate commitments to originate mortgage loans amounting to approximately $5,089,000 and loans held for sale of $1,639,000. Risks arise from the possible inability of counterparties to meet the terms of their contracts, though the Company has never experienced a failure of one of its counterparties to perform.  If a loan becomes past due 90 days within 180 days of sale, the Company would be required to repurchase the loan.

88

Note 16 – Related Party Transactions

In the ordinary course of business, loans are granted to executive officers, directors, and their related entities.  Management believes that all such loans are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans to similar, unrelated borrowers, and do not involve more than a normal risk of collectibility or present other unfavorable features.  As of December 31, 2017 and 2016, none of these loans were restructured, past due, or on nonaccrual status.

An analysis of these loans for 2017 is as follows (dollars in thousands):

Balance at December 31, 2016	$	22,078
Additions	24,265
Repayments	(20,589		)
Reclassifications(1)	(11,533		)
Balance at December 31, 2017	$	14,221

(1) Includes loans (i) to persons no longer affiliated with the Company and therefore not considered related party loans as of period end or (ii) that were considered related party loans in the prior year but were subsequently not considered related party loans in the current year.

Related party deposits totaled $22,077,000 at December 31, 2017 and $22,121,000 at December 31, 2016.

Note 17 – Employee Benefit Plans

Defined Benefit Plan

The Company previously maintained a non-contributory defined benefit pension plan which covered substantially all employees who were 21 years of age or older and who had at least one year of service.  The Company froze its pension plan to new participants and converted its pension plan to a cash balance plan effective December 31, 2009.  Each year existing participants will receive, with some adjustments, income based on the yield of the 10 year U.S. Treasury Note in December of the preceding year.

The accumulated benefit obligation as of December 31, 2017, 2016, and 2015 was $8,313,000, $7,932,000, and $8,453,000, respectively.  The rate of compensation increase is no longer applicable since the defined benefit plan was frozen and converted to a cash balance plan.

The plan sponsor selected the expected long-term rate-of-return-on-assets assumption in consultation with their investment advisors and actuary.  This rate was intended to reflect the average rate of earnings expected to be earned on the funds invested or to be invested to provide plan benefits.  Historical performance is reviewed, especially with respect to real rates of return (net of inflation), for the major asset classes held or anticipated to be held by the trust, and for the trust itself.  Undue weight is not given to recent experience that may not continue over the measurement period, with higher significance placed on current forecasts of future long-term economic conditions.

Because assets are held in a qualified trust, anticipated returns are not reduced for taxes.  Further, solely for this purpose, the plan is assumed to continue in force and not terminate during the period in which assets are invested.  However, consideration is given to the potential impact of current and future investment policy, cash flow into and out of the trust, and expenses (both investment and non-investment) typically paid from plan assets (to the extent such expenses are not explicitly estimated within periodic cost).

Below is a description of the plan's assets.  The plan's weighted-average asset allocations by asset category are as follows as of December 31, 2017 and 2016:

Asset Category	December 31,
	2017		2016
Fixed Income	61.7	%	51.3	%
Equity	29.5	%	38.0	%
Cash and Accrued Income	8.8	%	10.7	%
Total	100.0	%	100.0	%

The investment policy and strategy for plan assets can best be described as a growth and income strategy.  Diversification is accomplished by limiting the holding of any one equity issuer to no more than 5% of total equities.  Exchange traded funds are used to provide diversified exposure to the small capitalization and international equity markets.  All fixed income investments are rated as investment grade, with the majority of these assets invested in corporate issues.  The assets are managed by the Company's Trust and Investment Services Division.  No derivatives are used to manage the assets.  Equity securities do not include holdings in the Company.

The fair value of the Company's pension plan assets at December 31, 2017 and 2016, by asset category are as follows (dollars in thousands):

401(k) Plan

The Company maintains a 401(k) plan that covers substantially all full-time employees of the Company. The Company matches a portion of the contribution made by employee participants after at least one year of service. The Company contributed $763,000, $623,000, and $602,000 to the 401(k) plan in 2017, 2016, and 2015, respectively. These amounts are included in employee benefits expense for the respective years.

Deferred Compensation Arrangements

The Company has historically maintained deferred compensation agreements with certain current and former employees providing for annual payments to each ranging from $25,000 to $50,000 per year for ten years upon their retirement.  The liabilities under these agreements are being accrued over the officers' remaining periods of employment so that, on the date of their retirement, the then-present value of the annual payments would have been accrued.  As of December 31, 2017, the Company only had one remaining agreement under which payments are being made to a former officer. The liabilities were $350,000 and $397,000 at December 31, 2017 and 2016, respectively. The expense for these agreements was $3,000, $6,000, and $8,000 for the years ended December 31, 2017, 2016, and 2015, respectively.

Incentive Arrangements

The Company maintains a cash incentive compensation plan for officers based on the Company's performance and individual officer goals.  The total amount charged to salary expense for this plan was $1,243,000, $916,000, and $559,000 for the years ended December 31, 2017, 2016, and 2015, respectively.

Note 18 – Fair Value Measurements

Determination of Fair Value

The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with the fair value measurements and disclosures topic of FASB ASC, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company's various financial instruments. In cases

92

where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions.

Fair Value Hierarchy

In accordance with this guidance, the Company groups its financial assets and financial liabilities generally measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value.

Level 1 –	Valuation is based on quoted prices in active markets for identical assets and liabilities.
Level 2 –	Valuation is based on observable inputs including quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets and liabilities in less active markets, and model-based valuation techniques for which significant assumptions can be derived primarily from or corroborated by observable data in the market.
Level 3 –	Valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market.

The following describes the valuation techniques used by the Company to measure certain financial assets and liabilities recorded at fair value on a recurring basis in the financial statements:

Securities available for sale: Securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Third party vendors compile prices from various sources and may determine the fair value of identical or similar securities by using pricing models that consider observable market data (Level 2).

The following table presents the balances of financial assets measured at fair value on a recurring basis during the period (dollars in thousands):

Certain assets are measured at fair value on a nonrecurring basis in accordance with GAAP. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets.

The following describes the valuation techniques used by the Company to measure certain assets recorded at fair value on a nonrecurring basis in the financial statements:

Loans held for sale: Loans held for sale are carried at fair value. These loans currently consist of one-to-four family residential loans originated for sale in the secondary market. Fair value is based on the price secondary markets are currently offering for similar loans using observable market data which is not materially different than cost due to the short duration between origination and sale (Level 2). As such, the Company records any fair value adjustments on a nonrecurring basis. No nonrecurring fair value adjustments were recorded on loans held for sale during the years ended December 31, 2017 and 2016. Gains and losses on the sale of loans are recorded within mortgage banking income on the Consolidated Statements of Income.

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 according to the contractual terms of the loan agreements will not be collected when due.  The measurement of loss associated with impaired loans can be based on either the observable market price of the loan or the fair value of the collateral.  Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable.  The vast majority of the Company's collateral is real estate.  The value of real estate collateral is determined utilizing a market valuation approach based on an appraisal, of one year or less, conducted by an independent, licensed appraiser using observable market data (Level 2).  However, if the collateral is a house or building in the process of construction or if an appraisal of the property is more than one year old and not solely based on observable market comparable or management determines the fair value of the collateral is further impaired below the appraised value, then a Level 3 valuation is considered to measure the fair value.  The value of business equipment is based upon an outside appraisal, of one year or less, if deemed significant, or the net book value on the applicable business's financial statements if not considered significant using observable market data.  Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (Level 3).  Impaired loans allocated to the allowance for loan losses are measured at fair value on a nonrecurring basis.  Any fair value adjustments are recorded in the period incurred as provision for loan losses on the Consolidated Statements of Income.

Other real estate owned:  Measurement for fair values for other real estate owned are the same as impaired loans.  Any fair value adjustments are recorded in the period incurred as a valuation allowance against other real estate owned with the associated expense included in other real estate owned expense, net on the Consolidated Statements of Income.

The following methods and assumptions were used by the Company in estimating fair value disclosures for financial instruments:

Cash and cash equivalents.  The carrying amount is a reasonable estimate of fair value.

Securities.  Fair values are based on quoted market prices or dealer quotes.

Restricted stock.  The carrying value of restricted stock approximates fair value based on the redemption provisions of the respective entity.

Loans held for sale.  The carrying amount is at fair value.

Loans.  For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values.  Fair values for fixed-rate loans are estimated based upon discounted cash flow analysis, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.  Fair values for nonperforming loans are estimated using discounted cash flow analysis or underlying collateral values, where applicable.

Bank owned life insurance. Bank owned life insurance represents insurance policies on officers, directors, and past directors of the Company.  The cash value of the policies are estimates using information provided by insurance carriers.  These policies are carried at their cash surrender value, which approximates the fair value.

Accrued interest receivable.  The carrying amount is a reasonable estimate of fair value.

Deposits.  The fair value of demand deposits, savings deposits, and money market deposits equals the carrying value. The fair value of fixed-rate certificates of deposit is estimated by discounting the future cash flows using the current rates at which similar deposit instruments would be offered to depositors for the same remaining maturities.

Repurchase agreements.  The carrying amount is a reasonable estimate of fair value.

Other short-term borrowings.  The carrying amount is a reasonable estimate of fair value.

Long-term borrowings.  The fair values of long-term borrowings are estimated using discounted cash flow analysis based on the interest rates for similar types of borrowing arrangements.

Junior subordinated debt.  Fair value is calculated by discounting the future cash flows using the estimated current interest rates at which similar securities would be issued.

Accrued interest payable.  The carrying amount is a reasonable estimate of fair value.

Off-balance sheet instruments.  The fair value of letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date.  At December 31, 2017 and 2016, the fair value of off balance sheet instruments was deemed immaterial, and therefore was not included in the table above.  The various off-balance sheet instruments were discussed in Note 15.

The Company assumes interest rate risk (the risk that interest rates will change) in its normal operations.  As a result, the fair values of the Company's financial instruments will change when interest rates change and that change may be either favorable or unfavorable to the Company.

Note 19 – Dividend Restrictions and Regulatory Capital

The approval of the Office of the Comptroller of the Currency is required if the total of all dividends declared by a national bank in any calendar year exceeds the bank's retained net income, as defined, for that year combined with its retained net income for the preceding two calendar years.  Under this formula, the Bank can distribute as dividends to the Company, without the approval of the Office of the Comptroller of the Currency, $16,011,000 as of December 31, 2017. Dividends paid by the Bank to the Company are the only significant source of funding for dividends paid by the Company to its shareholders.

Banks and bank holding companies are subject to various regulatory capital requirements administered by federal banking agencies.  Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate certain regulatory action. The final rules implementing Basel Committee on Banking Supervision's capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased-in over a multi-year schedule, and fully phased-in by January 1, 2019. The net unrealized gain or

97

loss on available for sale securities and unfunded pension liability is included in computing regulatory capital. Management believes as of December 31, 2017, the Company and Bank meet all capital adequacy requirements to which they are subject.

Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At year-end 2017 and 2016, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank's category.

Actual and required capital amounts (in thousands) and ratios are presented below at year-end:

* Except with regard to the Company's and the Bank's leverage capital ratio, includes the current phased-in portion of the Basel III Capital Rules capital conservation buffer which is added to the minimum capital requirements for capital adequacy purposes. The capital conservation buffer requirement began being phased-in effective January 1, 2016, at 0.625% of risk-weighted assets, increasing by the same amount each year until fully implemented at 2.5% on January 1, 2019. The capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of common equity Tier 1 to risk-weighted assets above the minimum but below the conservation buffer will face constraints on dividends, equity repurchases, and compensation based on the amount of the shortfall.

Note 20 – Segment and Related Information

The Company has two reportable segments, community banking and trust and investment services.

Community banking involves making loans to and generating deposits from individuals and businesses.  All assets and liabilities of the Company are allocated to community banking.  Investment income from securities is also allocated to the community banking segment.  Loan fee income, service charges from deposit accounts, and non-deposit fees such as automated teller machine fees and insurance commissions generate additional income for the community banking segment.

Trust and investment services include estate planning, trust account administration, investment management, and retail brokerage.  Investment management services include purchasing equity, fixed income, and mutual fund investments for customer accounts. The trust and investment services segment receives fees for investment and administrative services.

Amounts shown in the "Other" column include activities of the Company which are primarily debt service on trust preferred securities and corporate items. 

Segment information as of and for the years ended December 31, 2017, 2016, and 2015, is shown in the following table (dollars in thousands):

ITEM 9A – CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The Company's management, including the Chief Executive Officer and Chief Financial Officer, evaluated the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act), as of December 31, 2017. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures are effective to ensure that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms. There were no significant changes in the Company's internal controls over financial reporting that occurred during the quarter ended December 31, 2017 that have materially affected or are reasonably likely to materially affect the Company's internal control over financial reporting.

Management's Annual Report on Internal Control over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting.  Internal control is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.  Management regularly monitors its internal control over financial reporting, and actions are taken to correct deficiencies as they are identified.

Under the supervision and with the participation of management, including the principal executive officer and principal financial officer, the Company conducted an evaluation of the effectiveness of internal control over financial reporting.  This assessment was based on the framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.  Based on this evaluation under the framework in Internal Control – Integrated Framework, management concluded that the Company maintained effective internal control over financial reporting as of December 31, 2017, as such term is defined in Exchange Act Rule 13a-15(f).

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Further, because of changes in conditions, internal control effectiveness may vary over time.

The Company's independent registered public accounting firm, Yount, Hyde and Barbour, P.C., has audited the Company's internal control over financial reporting as of December 31, 2017, as stated in their report included herein.  Yount, Hyde and Barbour, P.C. also audited the Company's consolidated financial statements as of and for the year ended December 31, 2017.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Nature of Operations and Consolidation

The consolidated financial statements include the accounts of American National Bankshares Inc. (the "Company") and its wholly owned subsidiary, American National Bank and Trust Company (the "Bank").  The Bank offers a wide variety of retail, commercial, secondary market mortgage lending, and trust and investment services which also include non-deposit products such as mutual funds and insurance policies.

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, goodwill and intangible assets, unfunded pension liability, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, the valuation of other real estate owned ("OREO"), and the valuation of deferred tax assets and liabilities.

In April 2006, AMNB Statutory Trust I, a Delaware statutory trust (the "AMNB Trust") and an unconsolidated wholly owned subsidiary of the Company, was formed for the purpose of issuing preferred securities (the "Trust Preferred Securities") in a private placement pursuant to an applicable exemption from registration.  Proceeds from the securities were used to fund the acquisition of Community First Financial Corporation ("Community First") which occurred in April 2006.

On July 1, 2011, the Company completed its acquisition of MidCarolina Financial Corporation ("MidCarolina") pursuant to the terms and conditions of the Agreement and Plan of Reorganization, dated December 15, 2010, between the Company and MidCarolina.  MidCarolina was headquartered in Burlington, North Carolina, and engaged in banking operations through its subsidiary bank, MidCarolina Bank.  The transaction has expanded the Company's footprint in North Carolina, adding eight branches in Alamance and Guilford Counties.

In July 2011, and in connection with its acquisition of MidCarolina, the Company assumed liabilities of the MidCarolina Trust I and MidCarolina Trust II, two separate unconsolidated Delaware statutory trusts (the "MidCarolina Trusts"), which were also formed for the purpose of issuing preferred securities.  Refer to Note 11 for further details concerning these entities.

On January 1, 2015, the Company completed its acquisition of MainStreet BankShares, Inc. ("MainStreet") pursuant to the terms and conditions of the Agreement and Plan of Reorganization, dated as of August 24, 2014, between the Company and MainStreet (the "MainStreet Merger Agreement"). Immediately after the merger of MainStreet into the Company, Franklin Community Bank, N.A., MainStreet's wholly-owned bank subsidiary ("Franklin Bank"), merged with and into the Bank. Franklin Bank provided banking services to its customers from three banking offices located in Rocky Mount, Hardy, and Union Hall, Virginia.

All significant inter-company transactions and accounts are eliminated in consolidation, with the exception of the AMNB Trust and the MidCarolina Trusts, as detailed in Note 11.

Cash and Cash Equivalents

Cash includes cash on hand, cash with correspondent banks, and cash on deposit at the Federal Reserve Bank of Richmond.  Cash equivalents are short-term, highly liquid investments that are readily convertible to cash with original maturities of three months or less and are subject to an insignificant risk of change in value.  Cash and cash equivalents are carried at cost.

Interest-bearing Deposits in Other Banks

Interest-bearing deposits in other banks mature within one year and are carried at cost.

Securities

Certain debt securities that management has the positive intent and ability to hold to maturity are classified as "held to maturity" and recorded at amortized cost. Trading securities are recorded at fair value with changes in fair value included in earnings. Securities not classified as held to maturity or trading, including equity securities with readily determinable fair values, are classified as "available for sale" and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.

The Company does not currently have any securities in held to maturity or trading and has no plans to add any to either category. Management evaluates securities for other-than-temporary impairment ("OTTI") on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement and, (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.

Due to the nature and restrictions placed on the Company's investment in common stock of the Federal Home Loan Bank of Atlanta ("FHLB") and the Federal Reserve Bank of Richmond, these securities have been classified as restricted equity securities and carried at cost.

Loans Held for Sale

Secondary market mortgage loans are designated as held for sale at the time of their origination.  These loans are pre-sold with servicing released and the Company does not retain any interest after the loans are sold.  These loans consist primarily of fixed-rate, single-family residential mortgage loans which meet the underwriting characteristics of certain government-sponsored enterprises (conforming loans).  In addition, the Company requires a firm purchase commitment from a permanent investor before a loan can be committed, thus limiting interest rate risk.  Loans held for sale are carried at fair value.  Gains on sales of loans are recognized at the loan closing date and are included in noninterest income.

Derivative Loan Commitments

The Company enters into mortgage loan commitments whereby the interest rate on the loan is determined prior to funding (rate lock commitments).  Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding.  Loan commitments that are derivatives are recognized at fair value on the consolidated balance sheets with net changes in their fair values recorded in other expenses.  Derivative loan commitments resulted in no income or loss for 2017, 2016 or 2015.

The period of time between issuance of a loan commitment and sale of the loan generally ranges from 30 to 60 days. The Company protects itself from changes in interest rates through the use of best efforts forward delivery contracts, by committing to sell a loan at the time the borrower commits to an interest rate with the intent that the buyer has assumed the interest rate risk on the loan.  As a result, the Company is not generally exposed to significant losses nor will it realize significant gains related to its rate lock commitments due to changes in interest rates.  The correlation between the rate lock commitments and the best efforts contracts is very high due to their similarity.

The fair value of rate lock commitments and best efforts contracts is not readily ascertainable with precision because rate lock commitments and best efforts contracts are not actively traded in stand-alone markets.  The Company determines the fair value of rate lock commitments and best efforts contracts by measuring the change in the estimated value of the underlying assets while taking into consideration the probability that the loan will be funded.

Loans

The Company makes mortgage, commercial, and consumer loans.  A substantial portion of the loan portfolio is secured by real estate.  The ability of the Company's debtors to honor their contracts is dependent upon the real estate market and general economic conditions in the Company's market area.

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off, generally are reported at their outstanding unpaid principal balance adjusted for the allowance for loan losses, and any deferred fees or costs.  Interest income is accrued on the unpaid principal balance.  Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. The accrual of interest on loans is generally discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection.  Loans are typically charged off when the loan is 120 days past due, unless secured and in process of collection.  Loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful.

Interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income.  The interest on these loans is accounted for on the cash basis or cost recovery method, until qualifying for return to accrual status.  Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

A loan is considered past due when a payment of principal or interest or both is due but not paid.  Management closely monitors past due loans in timeframes of 30-59 days, 60-89 days, and 90 or more days past due.

These policies apply to all loan portfolio classes and segments.

Substandard and doubtful risk graded commercial, commercial real estate, and construction loans equal to or greater than $100,000 are reviewed for impairment. All troubled debt restructurings, regardless of dollar amount, are also evaluated for impairment. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement.  Factors considered by management in determining impairment and establishing a specific allowance include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due.  Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed.  Impairment is measured on a loan-by-loan basis for commercial, commercial real estate, and construction loans by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

Generally, large groups of smaller balance homogeneous loans (residential real estate and consumer loans) are collectively evaluated for impairment.  The Company's policy for recognizing interest income on impaired loans is consistent with its nonaccrual policy.

The Company's loan portfolio is organized by major segment. These include: commercial, commercial real estate, residential real estate and consumer loans.  Each segment has particular risk characteristics that are specific to the borrower and the generic category of credit.  Commercial loan repayments are highly dependent on cash flows associated with the underlying business and its profitability.  They can also be impacted by changes in collateral values.  Commercial real estate loans share the same general risk characteristics as commercial loans, but are often more dependent on the value of the underlying real estate collateral and, when construction is involved, the ultimate completion of and sale of the project.  Residential real estate loans are generally dependent on the value of collateral and the credit worthiness of the underlying borrower.  Consumer loans are very similar in risk characteristics to residential real estate.

In connection with the MidCarolina and MainStreet mergers, certain loans were acquired which exhibited deteriorated credit quality since origination and for which the Company does not expect to collect all contractual payments.  These purchased credit impaired loans are recorded at the amount paid, such that there is no carryover of the seller's allowance for loan losses.  After acquisition, losses are recognized by an increase in the allowance for loan losses.

Such purchased credit impaired loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as, credit score, loan type, and date of origination.  The Company estimates the amount and timing of expected cash flows for each loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield).  The excess of the loan's or pool's contractual principal and interest over expected cash flows is not recorded (nonaccretable difference).

Over the life of the loan or pool, expected cash flows continue to be estimated.  If the present value of expected cash flows is less than the carrying amount, a loss is recorded as a provision for loan losses.  If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income.

In situations where, for economic or legal reasons related to a borrower's financial condition, management may grant a concession to the borrower that it would not otherwise consider, the related loan is classified as a troubled debt restructuring ("TDRs").  Management strives to identify borrowers in financial difficulty early and work with them to modify their loan to more affordable terms before their loan reaches nonaccrual status.  These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral.  In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans.  The Company has $1,306,000 in loans classified as TDRs as of December 31, 2017 and $2,670,000 as of December 31, 2016.

Allowance for Loan Losses

The purpose of the allowance for loan losses ("ALLL") is to provide for probable losses inherent in the loan portfolio.  The allowance is increased by the provision for loan losses and by recoveries of previously charged-off loans.  Loan charge-offs decrease the allowance.

The goal of the Company is to maintain an appropriate, systematic, and consistently applied process to determine the amounts of the ALLL and the provision for loan loss expense.

The Company uses certain practices to manage its credit risk.  These practices include (1) appropriate lending limits for loan officers, (2) a loan approval process, (3) careful underwriting of loan requests, including analysis of borrowers, cash flows, collateral, and market risks, (4) regular monitoring of the portfolio, including diversification by type and geography, (5) review of loans by the Loan Review department, which operates independently of loan production (the Loan Review function consists of a co-sourced arrangement using both internal personnel and external vendors to provide the Company with a more robust review function of the loan portfolio), (6) regular meetings of the Credit Committees to discuss portfolio and policy changes and make decisions on large or unusual loan requests, and (7) regular meetings of the Asset Quality Committee which reviews the status of individual loans.

Risk grades are assigned as part of the loan origination process. From time to time risk grades may be modified as warranted by the facts and circumstances surrounding the credit.

Calculation and analysis of the allowance for loan losses is prepared quarterly by the Finance Department.  The Company's Credit Committee, Capital Management Committee, Audit Committee, and the Board of Directors review the allowance for adequacy.

The Company's allowance for loan losses has two basic components:  the formula allowance and the specific allowance.  Each of these components is determined based upon estimates and judgments.

The formula allowance uses historical loss experience as an indicator of future losses, along with various qualitative factors, including levels and trends in delinquencies, nonaccrual loans, charge-offs and recoveries, trends in volume and terms of loans, effects of changes in underwriting standards, experience of lending staff, economic conditions, and portfolio concentrations. In the formula allowance for commercial and commercial real estate loans, the historical loss rate is combined with the qualitative factors, resulting in an adjusted loss factor for each risk-grade category of loans.  The period-end balances for each loan risk-grade category are multiplied by the adjusted loss factor.  Allowance calculations for consumer loans are calculated based on historical losses for each product category without regard to risk grade. This loss rate is combined with qualitative factors resulting in an adjusted loss factor for each product category.

The specific allowance uses various techniques to arrive at an estimate of loss for specifically identified impaired loans. These include:

• The present value of expected future cash flows discounted at the loan's effective interest rate.  The effective interest rate on a loan is the rate of return implicit in the loan (that is, the contractual interest rate adjusted for any net deferred loan fees or costs and any premium or discount existing at the origination or acquisition of the loan);

• The loan's observable market price, or

• The fair value of the collateral, net of estimated costs to dispose, if the loan is collateral dependent.

The use of these computed values is inherently subjective and actual losses could be greater or less than the estimates. No single statistic, formula, or measurement determines the adequacy of the allowance.  Management makes subjective and complex judgments about matters that are inherently uncertain, and different amounts would be reported under different conditions or using different assumptions.  For analytical purposes, management allocates a portion of the allowance to specific loan categories and specific loans.  However, the entire allowance is used to absorb credit losses inherent in the loan portfolio, including identified and unidentified losses.

The relationships and ratios used in calculating the allowance, including the qualitative factors, may change from period to period as facts and circumstances evolve.  Furthermore, management cannot provide assurance that in any particular period the Company will not have sizeable credit losses in relation to the amount reserved.  Management may find it necessary to significantly adjust the allowance, considering current factors at the time.

Premises and Equipment

Land is carried at cost.  Premises and equipment are stated at cost, less accumulated depreciation and amortization.  Premises and equipment are depreciated over their estimated useful lives ranging from three years to thirty-nine years; leasehold improvements are amortized over the lives of the respective leases or the estimated useful lives of the improvements, whichever is less.  Software is generally amortized over three years.  Depreciation and amortization are recorded on the straight-line method.

Costs of maintenance and repairs are charged to expense as incurred.  Costs of replacing structural parts of major units are considered individually and are expensed or capitalized as the facts dictate.  Gains and losses on routine dispositions are reflected in current operations.

Goodwill and Intangible Assets

Goodwill is subject to at least an annual assessment for impairment by applying a fair value based test.  Additionally, acquired intangible assets (such as core deposit intangibles) are separately recognized if the benefit of the assets can be sold, transferred, licensed, rented, or exchanged, and amortized over their useful lives.  Intangible assets related to branch transactions continued to amortize. The cost of purchased deposit relationships and other intangible assets, based on independent valuation, are being amortized over their estimated lives ranging from eight to ten years.

The Company records as goodwill the excess of purchase price over the fair value of the identifiable net assets acquired. Impairment testing is performed annually, as well as when an event triggering impairment may have occurred. The Company performs its annual analysis as of June 30 each fiscal year. Accounting guidance permits preliminary assessment of qualitative factors to determine whether more substantial impairment testing is required. The Company chose to bypass the preliminary assessment and utilized a two-step process for impairment testing of goodwill. The first step tests for impairment, while the second step, if necessary, measures the impairment.  No indicators of impairment were identified during the years ended December 31, 2017, 2016, or 2015.

Trust Assets

Securities and other property held by the trust and investment services segment in a fiduciary or agency capacity are not assets of the Company and are not included in the accompanying consolidated financial statements.

Other Real Estate Owned

Other real estate owned represents real estate that has been acquired through loan foreclosures or deeds received in lieu of loan payments. Generally, such properties are appraised at the time acquired, and are recorded at fair value less estimated selling costs.  Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in noninterest expense.

Bank Owned Life Insurance

The Company has acquired bank owned life insurance ("BOLI") in connection with three acquisitions. The asset is reflected as the cash surrender value of the policies as provided by the insurer on a monthly basis.

Transfers of Financial Assets

Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company – put presumptively beyond reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.

Income Taxes

The Company uses the balance sheet method to account for deferred income tax assets and liabilities.  Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws.

When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained.  The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any.  Tax positions taken are not offset or aggregated with other positions.  Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority.  The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination.  The Company had no liability for unrecognized tax benefits as of December 31, 2017 and 2016.

Stock-Based Compensation

Stock compensation accounting guidance Accounting Standards Codification ("ASC") 718, "Compensation – Stock Compensation" requires that the compensation cost relating to share-based payment transactions be recognized in financial statements.  That cost will be measured based on the grant date fair value of the equity or liability instruments issued.  The stock compensation accounting guidance covers a wide range of share-based compensation arrangements including stock options, restricted share plans, performance-based awards, share appreciation rights, and employee share purchase plans.

The stock compensation accounting guidance requires that compensation cost for all stock awards be calculated and recognized over the employees' service period, generally defined as the vesting period.  For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.  A Black-Scholes model is used to estimate the fair value of stock options, while the market price of the Company's common stock at the date of grant is used for restricted stock awards.

Earnings Per Common Share

Basic earnings per common share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share reflect the impact of additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company consist solely of outstanding stock options, and are determined using the treasury method. Nonvested shares of restricted stock are included in the computation of basic earnings per share because the holder has voting rights and shares in non-forfeitable dividends during the vesting period.

Comprehensive Income

Comprehensive income is shown in a two statement approach; the first statement presents total net income and its components followed by a second statement that presents all the components of other comprehensive income such as unrealized gains and losses on available for sale securities and changes in the funded status of a defined benefit postretirement plan.

In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”).  The Company early adopted this new standard in early 2018. ASU 2018-02 requires reclassification from AOCI to retained earnings for "stranded" tax effects resulting from the impact of the newly enacted federal corporate income tax rate on items included in AOCI.  The amount of this reclassification in 2017 was $545,000 and is reflected in the Consolidated Statements of Changes in Shareholders' equity.

Advertising and Marketing Costs

Advertising and marketing costs are expensed as incurred, and were $352,000, $260,000, and $356,000 in 2017, 2016, and 2015, respectively.

Mergers and Acquisitions

Business combinations are accounted for under ASC 805, "Business Combinations", using the acquisition method of accounting. The acquisition method of accounting requires an acquirer to recognize the assets acquired and the liabilities assumed at the acquisition date measured at their fair values as of that date. To determine the fair values, the Company relies on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Under the acquisition method of accounting, the Company identifies the acquirer and the closing date and applies applicable recognition principles and conditions. Acquisition-related costs are costs the Company incurs to effect a business combination. Those costs include advisory, legal, accounting, valuation, and other professional or consulting fees. Some other examples of costs to the Company include systems conversions, integration planning consultants and advertising costs. The Company accounts for acquisition-related costs as expenses in the periods in which the costs are incurred and the services are received, with one exception. The costs to issue debt or equity securities is recognized in accordance with other applicable GAAP. These acquisition-related costs have been and will be included within the Consolidated Statements of Income classified within the noninterest expense caption.

Reclassifications

Certain reclassifications have been made in prior years financial statements to conform to classifications used in the current year. There were no material reclassifications.

Use of Estimates

In preparing consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, goodwill and intangible assets, unfunded pension liability, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, the valuation of other real estate owned, and the valuation of deferred tax assets and liabilities.

Adoption of New Accounting Standards

During the first quarter of 2017, the Company adopted ASU No. 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employer Share-Based Payment Accounting."This ASU simplifies several aspects of the accounting for share-based payment award transactions, one of which is the recognition of excess tax benefits and deficiencies related to share-based payments, including tax benefits of dividends on share-based payment awards. Prior to the adoption of ASU 2016-09, such tax consequences were recognized as components of additional paid-in capital. With the adoption of this ASU, tax benefits and deficiencies are recognized within income tax expense. In accordance with the adoption provisions of ASU 2016-09, the results for 2016 and 2015 include only the excess tax (expense) benefits attributable to 2016 and 2015 in the amounts of $17,000 and $13,000, respectively.

During February 2018, the FASB issued ASU No. 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This ASU provides financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (the "Tax Reform Act"), or portion thereof, is recorded. The amendments are effective for all organizations for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. Organizations should apply the proposed amendments either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Reform Act is recognized. The Company has elected to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act of $545,000 in its consolidated financial statements for the period ended December 31, 2017.

Recent Accounting Pronouncements

In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The amendments in ASU 2016-01, among other things: (1) requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (2) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (3) Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables); and (4) eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not expect the adoption of ASU 2016-01 to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company has analyzed all leases currently in place and determined the adoption of ASU 2016-02 will not have a material impact on its consolidated financial statements.

During June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The amendments in this ASU are effective for Securities and Exchange Commission ("SEC") filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company has formed a committee to address the adoption of the standard and engaged a third party vendor to assist with the data gathering and analysis. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements.

During August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments", to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The amendments should be applied using a retrospective transition method to each period presented. If retrospective application is impractical for some of the issues addressed by the update, the amendments for those issues would be applied prospectively as of the earliest date practicable.Early adoption is permitted, including adoption in an interim period. The Company does not expect the adoption of ASU 2016-15 to have a material impact on its consolidated financial statements.

During January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business". The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the current implementation guidance in Topic 805, there are three elements of a business - inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a "set") that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this ASU provide a screen to determine when a set is not a business. If the screen is not met, the amendments (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The ASU provides a framework to assist entities in evaluating whether both an input and a substantive process are present. The amendments in this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The amendments in this ASU should be applied prospectively on or after the effective date. No disclosures are required at transition. The Company does not expect the adoption of ASU 2017-01 to have a material impact on its consolidated financial statements.

During January 2017, the FASB issued ASU No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of ASU 2017-04 to have a material impact on its consolidated financial statements.

During March 2017, the FASB issued ASU No. 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The amendments in this ASU require an employer that offers defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715 to report the service cost component of net periodic benefit cost in the same line item(s) as other compensation costs arising from services rendered during the period. The other components of net periodic benefit cost are required to be presented in the income statement separately from the service cost component. If the other components of net periodic benefit cost are not presented on a separate line or lines, the line item(s) used in the income statement must be disclosed. In addition, only the service cost component will be eligible for capitalization as part of an asset, when applicable. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted. The Company does not expect the adoption of ASU 2017-07 to have a material impact on its consolidated financial statements.

During March 2017, the FASB issued ASU No. 2017-08, “Receivables-Nonrefundable Fees and Other Costs (Subtopic 310‐20), Premium Amortization on Purchased Callable Debt Securities.” The amendments in this ASU shorten the amortization period for certain callable debt securities purchased at a premium. Upon adoption of the standard, premiums on these qualifying callable debt securities will be amortized to the earliest call date. Discounts on purchased debt securities will continue to be accreted to maturity. The amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Upon transition, entities should apply the guidance on a modified retrospective basis, with a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption and provide the disclosures required for a change in accounting principle. The Company is currently assessing the impact that ASU 2017-08 will have on its consolidated financial statements.

During May 2017, the FASB issued ASU No. 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting.” The amendments provide guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718.  The amendments are effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued. The Company is currently assessing the impact that ASU 2017-09 will have on its consolidated financial statements.

During August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” The amendments in this ASU modify the designation and measurement guidance for hedge accounting as well as provide for increased transparency regarding the presentation of economic results on both the financial statements and related footnotes. Certain aspects of hedge effectiveness assessments will also be simplified upon implementation of this update. The amendments are effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period. The Company does not expect the adoption of ASU 2017-12 to have a material impact on its consolidated financial statements.

Cash and Cash Equivalents [Abstract]

Restrictions on Cash

Restrictions on Cash

The Company is a member of the Federal Reserve System and is required to maintain certain levels of its cash and cash equivalents as reserves based on regulatory requirements. The gross reserve requirement with the Federal Reserve Bank of Richmond was $2.8 million and $2.3 million at December 31, 2017 and December 31, 2016, respectively. Due to vault cash that exceeded the gross reserve requirement, the balance to be maintained with the Federal Reserve Bank of Richmond was zero at both year ends.

The Company maintains cash accounts in other commercial banks.  The amount on deposit with correspondent institutions at December 31, 2017 exceeded the insurance limits of the Federal Deposit Insurance Corporation by $239,000.

The amortized cost and estimated fair value of investments in securities at December 31, 2017, by contractual maturity, are shown in the following table.  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.  Because mortgage-backed securities have both known principal repayment terms as well as unknown principal repayments due to potential borrower pre-payments, it is difficult to accurately predict the final maturity of these investments.  Mortgage-backed securities are shown separately (dollars in thousands):

	Available for Sale
	Amortized Cost		Fair Value

Federal agencies and GSEs: The unrealized losses on the Company's investment in 24 government sponsored entities ("GSE") were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2017.

Mortgage-backed securities: The unrealized losses on the Company's investment in 53 GSE mortgage-backed securities were caused by interest rate increases. Sixteen of these securities were in an unrealized loss position for 12 months or more. The contractual cash flows of those investments are guaranteed by an agency of the U.S. Government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost bases of the Company's investments. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2017.

Collateralized Mortgage Obligations: The unrealized loss associated with one private GSE collateralized mortgage obligation ("CMO") is due to normal market fluctuations. This security has been in an unrealized loss position for 12 months or more. The contractual cash flows of those investments are guaranteed by an agency of the U.S. Government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost bases of the Company's investments. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2017.

State and municipal securities:  The unrealized losses on 50 state and municipal securities were caused by interest rate increases and not credit deterioration. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2017.

Corporate securities:  The unrealized losses on two corporate securities were caused by interest rate increases and not credit deterioration. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2017.

Due to restrictions placed upon the Bank's common stock investment in the Federal Reserve Bank of Richmond and FHLB, these securities have been classified as restricted equity securities and carried at cost. These restricted securities are not subject to the investment security classifications and are included as a separate line item on the Company's Consolidated Balance Sheet. The FHLB requires the Bank to maintain stock in an amount equal to 4.25% of outstanding borrowings and a specific percentage of the Bank's total assets. The Federal Reserve Bank of Richmond requires the Bank to maintain stock with a par value equal to 3.0% of its outstanding capital and an additional 3.0% is on call. Restricted equity securities consist of Federal Reserve Bank of Richmond stock in the amount of $3,587,000 and $3,559,000 as of December 31, 2017 and 2016 and FHLB stock in the amount of $2,523,000 and $2,665,000 as of December 31, 2017 and 2016, respectively.

During the year ended December 31, 2017, there were three commercial loans with a total recorded investment of $109,000 and one residential real estate loan with a recorded investment of $143,000 that defaulted within twelve months of modification. During the years ended December 31, 2016 and 2015, the Company had no loans that subsequently defaulted within twelve months of modification.  The Company defines default as one or more payments that occur more than 90 days past the due date, charge-off or foreclosure subsequent to modification. Any charge-offs resulting in default were adjusted through the allowance for loan losses.

The following table summarizes the primary reason certain loan modifications were classified as TDRs and includes newly designated TDRs as well as modifications made to existing TDRs. Rate modifications include TDRs made with below market interest rates that also include modifications of loan structures (dollars in thousands):

Performing	$	4,415
Nonperforming	13
Total	$	4,428

Loans classified in the Pass category typically are fundamentally sound and risk factors are reasonable and acceptable.

Loans classified in the Special Mention category typically have been criticized internally, by loan review or the loan officer, or by external regulators under the current credit policy regarding risk grades.

Loans classified in the Substandard category typically have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt; they are typically characterized by the possibility that the Bank will sustain some loss if the deficiencies are not corrected.

Loans classified in the Doubtful category typically have all the weaknesses inherent in loans classified as substandard, plus the added characteristic the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions, and values highly questionable and improbable. However, these loans are not yet rated as loss because certain events may occur that may salvage the debt.

Consumer loans are classified as performing or nonperforming.  A loan is nonperforming when payments of interest and principal are past due 90 days or more, or payments are less than 90 days past due, but there are other good reasons to doubt that payment will be made in full.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets

The Company records as goodwill the excess of purchase price over the fair value of the identifiable net assets acquired. Impairment testing is performed annually, as well as when an event triggering impairment may have occurred. The Company performs its annual analysis as of June 30 each fiscal year. Accounting guidance permits preliminary assessment of qualitative factors to determine whether more substantial impairment testing is required. The Company chose to bypass the preliminary assessment and utilized a two-step process for impairment testing of goodwill. The first step tests for impairment, while the second step, if necessary, measures the impairment.  No indicators of impairment were identified during the years ended December 31, 2017, 2016, or 2015.

Core deposit intangibles resulting from the Community First acquisition in April 2006 were $3,112,000 and were amortized over 99 months ending in 2015.

Trust Preferred Capital Notes [Abstract]

Junior Subordinated Debt

Junior Subordinated Debt

On April 7, 2006, AMNB Statutory Trust I, a Delaware statutory trust and a wholly owned subsidiary of the Company, issued $20,000,000 of preferred securities in a private placement pursuant to an applicable exemption from registration.  The Trust Preferred Securities mature on June 30, 2036, but may be redeemed at the Company's option beginning on September 30, 2011.  Initially, the securities required quarterly distributions by the trust to the holder of the Trust Preferred Securities at a fixed rate of 6.66%.  Effective September 30, 2011, the rate resets quarterly at the three-month LIBOR plus 1.35%.  Distributions are cumulative and will accrue from the date of original issuance, but may be deferred by the Company from time to time for up to 20 consecutive quarterly periods.  The Company has guaranteed the payment of all required distributions on the Trust Preferred Securities. The proceeds of the Trust Preferred Securities received by the trust, along with proceeds of $619,000 received by the trust from the issuance of common securities by the trust to the Company, were used to purchase $20,619,000 of the Company's junior subordinated debt securities (the "Trust Preferred Capital Notes"), issued pursuant to a junior subordinated debentures entered into between the Company and Wilmington Trust Company, as trustee.  The proceeds of the Trust Preferred Capital Notes were used to fund the cash portion of the merger consideration to the former shareholders of Community First in connection with the Company's acquisition of that company, and for general corporate purposes.

On July 1, 2011, in connection with the MidCarolina merger, the Company assumed $8,764,000 in junior subordinated debentures to the MidCarolina Trusts, to fully and unconditionally guarantee the preferred securities issued by the MidCarolina Trusts. These long-term obligations, which currently qualify as Tier 1 capital, constitute a full and unconditional guarantee by the Company of the MidCarolina Trusts' obligations. The MidCarolina Trusts are not consolidated in the Company's financial statements.

In accordance with ASC 810-10-15-14, "Consolidation – Overall - Scope and Scope Exceptions," the Company did not eliminate through consolidation the Company's $619,000 equity investment in AMNB Statutory Trust I or the $264,000 equity investment in the MidCarolina Trusts.  Instead, the Company reflected this equity investment in the "Accrued interest receivable and other assets" line item in the consolidated balance sheets.

A description of the junior subordinated debt securities outstanding payable to the trusts is shown below (dollars in thousands):

				Principal Amount

The principal amounts reflected for the MidCarolina Trusts as of December 31, 2017 and 2016, are net of fair value marks of $833,000 and $724,000, respectively. The original fair value marks of $1,197,000 and $1,021,000 were recorded as a result of the merger with MidCarolina on July 1, 2011 and are being amortized into interest expense over the remaining lives of the respective borrowings.

Stock-Based Compensation

Stock-Based Compensation

The Company's 2008 Stock Incentive Plan ("2008 Plan") was adopted by the Board of Directors of the Company on February 19, 2008 and approved by shareholders on April 22, 2008 at the Company's 2008 Annual Meeting of Shareholders.  Until its expiration date on February 18, 2018, the 2008 Plan provided for the granting of restricted stock awards, incentive and non-statutory options to employees and directors on a periodic basis, at the discretion of the Board of Directors or a Board designated committee. The 2008 Plan authorized the issuance of up to 500,000 shares of common stock. The 2008 Plan replaced the Company's stock option plan that was approved by the shareholders at the 1997 Annual Meeting, which terminated in 2006. The 2008 Plan terminated in February 2018. The Board will be proposing a 2018 Equity Compensation Plan for shareholder approval at the upcoming Annual Meeting.

Stock Options

Accounting guidance requires that compensation cost relating to share-based payment transactions be recognized in the financial statements with measurement based upon the fair value of the equity or liability instruments issued.

A summary of stock option transactions for the year ended December 31, 2017 is as follows:

	Option Shares		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value ($000)
Outstanding at December 31, 2016	58,411		$	24.37
Replacement stock options	—		—

Exercisable at December 31, 2017	50,985		$	24.09	0.79 years	$	725

The aggregate intrinsic value of stock options in the table above represents the total pre-tax intrinsic value (the amount by which the current fair value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders had all option holders exercised their options on December 31, 2017.  This amount changes based on changes in the fair value of the Company's common stock.

The total proceeds of the in-the-money options exercised during the year ended December 31, 2017, 2016, and 2015 were $113,000, $142,000, and $789,000, respectively.  Total intrinsic value of options exercised during years ended December 31, 2017, 2016, and 2015 was $287,000, $11,000, and $220,000, respectively.

As of December 31, 2017, 2016, and 2015, there was no recognized or unrecognized compensation expense attributable to the outstanding stock options.

The following table summarizes information related to stock options outstanding on December 31, 2017:

$30.01 to $41.67	1,650	0.01	33.33
	50,985	0.79 years	$	24.09

No stock options were granted in 2017, 2016 and 2015.

Restricted Stock

The Company from time-to-time grants shares of restricted stock to key employees and non-employee directors.  These awards help align the interests of these employees and directors with the interests of the shareholders of the Company by providing economic value directly related to increases in the value of the Company's common stock.  The value of the stock awarded is established as the fair market value of the stock at the time of the grant.  The Company recognizes expense, equal to the total value of such awards, ratably over the vesting period of the stock grants. Restricted stock granted in 2017 cliff vests at the end of a 36-month period beginning on the date of grant. Nonvested restricted stock activity for the year ended December 31, 2017 is summarized in the following table:

Restricted Stock	Shares		Weighted Average Grant Date Value
Nonvested at December 31, 2016	50,822		$	23.21
Granted	14,453		34.74
Vested	(18,774	)	24.49
Forfeited	—		—
Nonvested at December 31, 2017	46,501		26.28

As of December 31, 2017, 2016, and 2015, there was $538,000, $568,000, and $340,000, respectively, in unrecognized compensation cost related to nonvested restricted stock granted under the 2008 Plan.  This cost is expected to be recognized over the next 12 to 36 months.  The share based compensation expense for nonvested restricted stock was $532,000, $444,000, and $322,000 during 2017, 2016, and 2015, respectively.

Starting in 2010, the Company began offering its outside directors alternatives with respect to director compensation. The regular monthly board retainer can be received quarterly in the form of either (i) $5,800 in cash or (ii) shares of immediately vested, but restricted stock, with a market value of $6,250. Monthly meeting fees can also be received as $725 per meeting in cash or $900 in immediately vested, but restricted stock.  For 2017, 11 of the 13 outside directors elected to receive stock in lieu of cash for either all of part of their retainer or meeting fees. Only outside directors receive board fees. The Company issued 13,093, 13,166 and 11,228 shares and recognized share based compensation expense of $484,000, $380,000, and $275,000 during 2017, 2016 and 2015, respectively.

Off Balance Sheet Activities [Abstract]

Off-Balance Sheet Activities

Off-Balance Sheet Activities

The Company is party to credit-related financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers.  These financial instruments include commitments to extend credit and standby letters of credit.  Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets.  The Company evaluates each customer's credit worthiness on a case-by-case basis.  The amount of collateral obtained, if applicable, is based on management's credit evaluation of the customer.

The Company's exposure to credit loss is represented by the contractual amount of these commitments.  The Company follows the same credit policies in making commitments as it does for on-balance sheet instruments.

The following off-balance sheet financial instruments whose contract amounts represent credit risk were outstanding at December 31, 2017 and 2016 (dollars in thousands):

	December 31,
	2017		2016
Commitments to extend credit	$	341,760	$	345,803
Standby letters of credit	13,647		4,088
Mortgage loan rate lock commitments	5,089		12,839

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. These commitments generally consist of unused portions of lines of credit issued to customers. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee.  Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party.  Those letters of credit are primarily issued to support public and private borrowing arrangements.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers.

At December 31, 2017, the Company had locked-rate commitments to originate mortgage loans amounting to approximately $5,089,000 and loans held for sale of $1,639,000. Risks arise from the possible inability of counterparties to meet the terms of their contracts, though the Company has never experienced a failure of one of its counterparties to perform.  If a loan becomes past due 90 days within 180 days of sale, the Company would be required to repurchase the loan.

The accumulated benefit obligation as of December 31, 2017, 2016, and 2015 was $8,313,000, $7,932,000, and $8,453,000, respectively.  The rate of compensation increase is no longer applicable since the defined benefit plan was frozen and converted to a cash balance plan.

The plan sponsor selected the expected long-term rate-of-return-on-assets assumption in consultation with their investment advisors and actuary.  This rate was intended to reflect the average rate of earnings expected to be earned on the funds invested or to be invested to provide plan benefits.  Historical performance is reviewed, especially with respect to real rates of return (net of inflation), for the major asset classes held or anticipated to be held by the trust, and for the trust itself.  Undue weight is not given to recent experience that may not continue over the measurement period, with higher significance placed on current forecasts of future long-term economic conditions.

Because assets are held in a qualified trust, anticipated returns are not reduced for taxes.  Further, solely for this purpose, the plan is assumed to continue in force and not terminate during the period in which assets are invested.  However, consideration is given to the potential impact of current and future investment policy, cash flow into and out of the trust, and expenses (both investment and non-investment) typically paid from plan assets (to the extent such expenses are not explicitly estimated within periodic cost).

Below is a description of the plan's assets.  The plan's weighted-average asset allocations by asset category are as follows as of December 31, 2017 and 2016:

Asset Category	December 31,
	2017		2016
Fixed Income	61.7	%	51.3	%
Equity	29.5	%	38.0	%
Cash and Accrued Income	8.8	%	10.7	%
Total	100.0	%	100.0	%

The investment policy and strategy for plan assets can best be described as a growth and income strategy.  Diversification is accomplished by limiting the holding of any one equity issuer to no more than 5% of total equities.  Exchange traded funds are used to provide diversified exposure to the small capitalization and international equity markets.  All fixed income investments are rated as investment grade, with the majority of these assets invested in corporate issues.  The assets are managed by the Company's Trust and Investment Services Division.  No derivatives are used to manage the assets.  Equity securities do not include holdings in the Company.

The fair value of the Company's pension plan assets at December 31, 2017 and 2016, by asset category are as follows (dollars in thousands):

401(k) Plan

The Company maintains a 401(k) plan that covers substantially all full-time employees of the Company. The Company matches a portion of the contribution made by employee participants after at least one year of service. The Company contributed $763,000, $623,000, and $602,000 to the 401(k) plan in 2017, 2016, and 2015, respectively. These amounts are included in employee benefits expense for the respective years.

Deferred Compensation Arrangements

The Company has historically maintained deferred compensation agreements with certain current and former employees providing for annual payments to each ranging from $25,000 to $50,000 per year for ten years upon their retirement.  The liabilities under these agreements are being accrued over the officers' remaining periods of employment so that, on the date of their retirement, the then-present value of the annual payments would have been accrued.  As of December 31, 2017, the Company only had one remaining agreement under which payments are being made to a former officer. The liabilities were $350,000 and $397,000 at December 31, 2017 and 2016, respectively. The expense for these agreements was $3,000, $6,000, and $8,000 for the years ended December 31, 2017, 2016, and 2015, respectively.

Incentive Arrangements

The Company maintains a cash incentive compensation plan for officers based on the Company's performance and individual officer goals.  The total amount charged to salary expense for this plan was $1,243,000, $916,000, and $559,000 for the years ended December 31, 2017, 2016, and 2015, respectively.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Determination of Fair Value

The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with the fair value measurements and disclosures topic of FASB ASC, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company's various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions.

Fair Value Hierarchy

In accordance with this guidance, the Company groups its financial assets and financial liabilities generally measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value.

Level 1 –	Valuation is based on quoted prices in active markets for identical assets and liabilities.
Level 2 –	Valuation is based on observable inputs including quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets and liabilities in less active markets, and model-based valuation techniques for which significant assumptions can be derived primarily from or corroborated by observable data in the market.
Level 3 –	Valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market.

The following describes the valuation techniques used by the Company to measure certain financial assets and liabilities recorded at fair value on a recurring basis in the financial statements:

Securities available for sale: Securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Third party vendors compile prices from various sources and may determine the fair value of identical or similar securities by using pricing models that consider observable market data (Level 2).

The following table presents the balances of financial assets measured at fair value on a recurring basis during the period (dollars in thousands):

Certain assets are measured at fair value on a nonrecurring basis in accordance with GAAP. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets.

The following describes the valuation techniques used by the Company to measure certain assets recorded at fair value on a nonrecurring basis in the financial statements:

Loans held for sale: Loans held for sale are carried at fair value. These loans currently consist of one-to-four family residential loans originated for sale in the secondary market. Fair value is based on the price secondary markets are currently offering for similar loans using observable market data which is not materially different than cost due to the short duration between origination and sale (Level 2). As such, the Company records any fair value adjustments on a nonrecurring basis. No nonrecurring fair value adjustments were recorded on loans held for sale during the years ended December 31, 2017 and 2016. Gains and losses on the sale of loans are recorded within mortgage banking income on the Consolidated Statements of Income.

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 according to the contractual terms of the loan agreements will not be collected when due.  The measurement of loss associated with impaired loans can be based on either the observable market price of the loan or the fair value of the collateral.  Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable.  The vast majority of the Company's collateral is real estate.  The value of real estate collateral is determined utilizing a market valuation approach based on an appraisal, of one year or less, conducted by an independent, licensed appraiser using observable market data (Level 2).  However, if the collateral is a house or building in the process of construction or if an appraisal of the property is more than one year old and not solely based on observable market comparable or management determines the fair value of the collateral is further impaired below the appraised value, then a Level 3 valuation is considered to measure the fair value.  The value of business equipment is based upon an outside appraisal, of one year or less, if deemed significant, or the net book value on the applicable business's financial statements if not considered significant using observable market data.  Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (Level 3).  Impaired loans allocated to the allowance for loan losses are measured at fair value on a nonrecurring basis.  Any fair value adjustments are recorded in the period incurred as provision for loan losses on the Consolidated Statements of Income.

Other real estate owned:  Measurement for fair values for other real estate owned are the same as impaired loans.  Any fair value adjustments are recorded in the period incurred as a valuation allowance against other real estate owned with the associated expense included in other real estate owned expense, net on the Consolidated Statements of Income.

The following table summarizes the Company's assets that were measured at fair value on a nonrecurring basis during the period (dollars in thousands):

The following methods and assumptions were used by the Company in estimating fair value disclosures for financial instruments:

Cash and cash equivalents.  The carrying amount is a reasonable estimate of fair value.

Securities.  Fair values are based on quoted market prices or dealer quotes.

Restricted stock.  The carrying value of restricted stock approximates fair value based on the redemption provisions of the respective entity.

Loans held for sale.  The carrying amount is at fair value.

Loans.  For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values.  Fair values for fixed-rate loans are estimated based upon discounted cash flow analysis, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.  Fair values for nonperforming loans are estimated using discounted cash flow analysis or underlying collateral values, where applicable.

Bank owned life insurance. Bank owned life insurance represents insurance policies on officers, directors, and past directors of the Company.  The cash value of the policies are estimates using information provided by insurance carriers.  These policies are carried at their cash surrender value, which approximates the fair value.

Accrued interest receivable.  The carrying amount is a reasonable estimate of fair value.

Deposits.  The fair value of demand deposits, savings deposits, and money market deposits equals the carrying value. The fair value of fixed-rate certificates of deposit is estimated by discounting the future cash flows using the current rates at which similar deposit instruments would be offered to depositors for the same remaining maturities.

Repurchase agreements.  The carrying amount is a reasonable estimate of fair value.

Other short-term borrowings.  The carrying amount is a reasonable estimate of fair value.

Long-term borrowings.  The fair values of long-term borrowings are estimated using discounted cash flow analysis based on the interest rates for similar types of borrowing arrangements.

Junior subordinated debt.  Fair value is calculated by discounting the future cash flows using the estimated current interest rates at which similar securities would be issued.

Accrued interest payable.  The carrying amount is a reasonable estimate of fair value.

Off-balance sheet instruments.  The fair value of letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date.  At December 31, 2017 and 2016, the fair value of off balance sheet instruments was deemed immaterial, and therefore was not included in the table above.  The various off-balance sheet instruments were discussed in Note 15.

The Company assumes interest rate risk (the risk that interest rates will change) in its normal operations.  As a result, the fair values of the Company's financial instruments will change when interest rates change and that change may be either favorable or unfavorable to the Company.

Dividend Restrictions and Regulatory Capital

Dividend Restrictions and Regulatory Capital

The approval of the Office of the Comptroller of the Currency is required if the total of all dividends declared by a national bank in any calendar year exceeds the bank's retained net income, as defined, for that year combined with its retained net income for the preceding two calendar years.  Under this formula, the Bank can distribute as dividends to the Company, without the approval of the Office of the Comptroller of the Currency, $16,011,000 as of December 31, 2017. Dividends paid by the Bank to the Company are the only significant source of funding for dividends paid by the Company to its shareholders.

Banks and bank holding companies are subject to various regulatory capital requirements administered by federal banking agencies.  Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate certain regulatory action. The final rules implementing Basel Committee on Banking Supervision's capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased-in over a multi-year schedule, and fully phased-in by January 1, 2019. The net unrealized gain or loss on available for sale securities and unfunded pension liability is included in computing regulatory capital. Management believes as of December 31, 2017, the Company and Bank meet all capital adequacy requirements to which they are subject.

Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At year-end 2017 and 2016, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank's category.

Actual and required capital amounts (in thousands) and ratios are presented below at year-end:

* Except with regard to the Company's and the Bank's leverage capital ratio, includes the current phased-in portion of the Basel III Capital Rules capital conservation buffer which is added to the minimum capital requirements for capital adequacy purposes. The capital conservation buffer requirement began being phased-in effective January 1, 2016, at 0.625% of risk-weighted assets, increasing by the same amount each year until fully implemented at 2.5% on January 1, 2019. The capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of common equity Tier 1 to risk-weighted assets above the minimum but below the conservation buffer will face constraints on dividends, equity repurchases, and compensation based on the amount of the shortfall.

Segment Reporting [Abstract]

Segment and Related Information

Segment and Related Information

The Company has two reportable segments, community banking and trust and investment services.

Community banking involves making loans to and generating deposits from individuals and businesses.  All assets and liabilities of the Company are allocated to community banking.  Investment income from securities is also allocated to the community banking segment.  Loan fee income, service charges from deposit accounts, and non-deposit fees such as automated teller machine fees and insurance commissions generate additional income for the community banking segment.

Trust and investment services include estate planning, trust account administration, investment management, and retail brokerage.  Investment management services include purchasing equity, fixed income, and mutual fund investments for customer accounts. The trust and investment services segment receives fees for investment and administrative services.

Amounts shown in the "Other" column include activities of the Company which are primarily debt service on trust preferred securities and corporate items. 

Segment information as of and for the years ended December 31, 2017, 2016, and 2015, is shown in the following table (dollars in thousands):

Concentrations of Credit Risk

Concentrations of Credit Risk

Substantially all of the Company's loans are made within its market area, which includes Southern and Central Virginia and the northern portion of Central North Carolina.  The ultimate collectibility of the Company's loan portfolio and the ability to realize the value of any underlying collateral, if necessary, are impacted by the economic conditions and real estate values of the market area.

Loans secured by real estate were $1,080,031,000, or 80.8% of the loan portfolio at December 31, 2017, and $951,073,000, or 81.6% of the loan portfolio at December 31, 2016.  Loans secured by commercial real estate represented the largest portion of loans at $637,701,000 at December 31, 2017 and $510,960,000 at December 31, 2016, 47.7% and 43.9%, respectively of total loans.  There were no concentrations of loans to any individual, group of individuals, business, or industry that exceeded 10% of total loans at December 31, 2017 or 2016.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2017

Accounting Policies [Abstract]

Nature of Operations and Consolidation

Nature of Operations and Consolidation

The consolidated financial statements include the accounts of American National Bankshares Inc. (the "Company") and its wholly owned subsidiary, American National Bank and Trust Company (the "Bank").  The Bank offers a wide variety of retail, commercial, secondary market mortgage lending, and trust and investment services which also include non-deposit products such as mutual funds and insurance policies.

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, goodwill and intangible assets, unfunded pension liability, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, the valuation of other real estate owned ("OREO"), and the valuation of deferred tax assets and liabilities.

In April 2006, AMNB Statutory Trust I, a Delaware statutory trust (the "AMNB Trust") and an unconsolidated wholly owned subsidiary of the Company, was formed for the purpose of issuing preferred securities (the "Trust Preferred Securities") in a private placement pursuant to an applicable exemption from registration.  Proceeds from the securities were used to fund the acquisition of Community First Financial Corporation ("Community First") which occurred in April 2006.

On July 1, 2011, the Company completed its acquisition of MidCarolina Financial Corporation ("MidCarolina") pursuant to the terms and conditions of the Agreement and Plan of Reorganization, dated December 15, 2010, between the Company and MidCarolina.  MidCarolina was headquartered in Burlington, North Carolina, and engaged in banking operations through its subsidiary bank, MidCarolina Bank.  The transaction has expanded the Company's footprint in North Carolina, adding eight branches in Alamance and Guilford Counties.

In July 2011, and in connection with its acquisition of MidCarolina, the Company assumed liabilities of the MidCarolina Trust I and MidCarolina Trust II, two separate unconsolidated Delaware statutory trusts (the "MidCarolina Trusts"), which were also formed for the purpose of issuing preferred securities.  Refer to Note 11 for further details concerning these entities.

On January 1, 2015, the Company completed its acquisition of MainStreet BankShares, Inc. ("MainStreet") pursuant to the terms and conditions of the Agreement and Plan of Reorganization, dated as of August 24, 2014, between the Company and MainStreet (the "MainStreet Merger Agreement"). Immediately after the merger of MainStreet into the Company, Franklin Community Bank, N.A., MainStreet's wholly-owned bank subsidiary ("Franklin Bank"), merged with and into the Bank. Franklin Bank provided banking services to its customers from three banking offices located in Rocky Mount, Hardy, and Union Hall, Virginia.

All significant inter-company transactions and accounts are eliminated in consolidation, with the exception of the AMNB Trust and the MidCarolina Trusts, as detailed in Note 11.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash includes cash on hand, cash with correspondent banks, and cash on deposit at the Federal Reserve Bank of Richmond.  Cash equivalents are short-term, highly liquid investments that are readily convertible to cash with original maturities of three months or less and are subject to an insignificant risk of change in value.  Cash and cash equivalents are carried at cost.

Interest-bearing Deposits in Other Banks

Interest-bearing Deposits in Other Banks

Interest-bearing deposits in other banks mature within one year and are carried at cost.

Securities

Securities

Certain debt securities that management has the positive intent and ability to hold to maturity are classified as "held to maturity" and recorded at amortized cost. Trading securities are recorded at fair value with changes in fair value included in earnings. Securities not classified as held to maturity or trading, including equity securities with readily determinable fair values, are classified as "available for sale" and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.

The Company does not currently have any securities in held to maturity or trading and has no plans to add any to either category. Management evaluates securities for other-than-temporary impairment ("OTTI") on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement and, (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.

Due to the nature and restrictions placed on the Company's investment in common stock of the Federal Home Loan Bank of Atlanta ("FHLB") and the Federal Reserve Bank of Richmond, these securities have been classified as restricted equity securities and carried at cost.

Loans Held for Sale

Loans Held for Sale

Secondary market mortgage loans are designated as held for sale at the time of their origination.  These loans are pre-sold with servicing released and the Company does not retain any interest after the loans are sold.  These loans consist primarily of fixed-rate, single-family residential mortgage loans which meet the underwriting characteristics of certain government-sponsored enterprises (conforming loans).  In addition, the Company requires a firm purchase commitment from a permanent investor before a loan can be committed, thus limiting interest rate risk.  Loans held for sale are carried at fair value.  Gains on sales of loans are recognized at the loan closing date and are included in noninterest income.

Derivative Loan Commitments

Derivative Loan Commitments

The Company enters into mortgage loan commitments whereby the interest rate on the loan is determined prior to funding (rate lock commitments).  Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding.  Loan commitments that are derivatives are recognized at fair value on the consolidated balance sheets with net changes in their fair values recorded in other expenses.  Derivative loan commitments resulted in no income or loss for 2017, 2016 or 2015.

The period of time between issuance of a loan commitment and sale of the loan generally ranges from 30 to 60 days. The Company protects itself from changes in interest rates through the use of best efforts forward delivery contracts, by committing to sell a loan at the time the borrower commits to an interest rate with the intent that the buyer has assumed the interest rate risk on the loan.  As a result, the Company is not generally exposed to significant losses nor will it realize significant gains related to its rate lock commitments due to changes in interest rates.  The correlation between the rate lock commitments and the best efforts contracts is very high due to their similarity.

The fair value of rate lock commitments and best efforts contracts is not readily ascertainable with precision because rate lock commitments and best efforts contracts are not actively traded in stand-alone markets.  The Company determines the fair value of rate lock commitments and best efforts contracts by measuring the change in the estimated value of the underlying assets while taking into consideration the probability that the loan will be funded.

Loans

Loans

The Company makes mortgage, commercial, and consumer loans.  A substantial portion of the loan portfolio is secured by real estate.  The ability of the Company's debtors to honor their contracts is dependent upon the real estate market and general economic conditions in the Company's market area.

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off, generally are reported at their outstanding unpaid principal balance adjusted for the allowance for loan losses, and any deferred fees or costs.  Interest income is accrued on the unpaid principal balance.  Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. The accrual of interest on loans is generally discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection.  Loans are typically charged off when the loan is 120 days past due, unless secured and in process of collection.  Loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful.

Interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income.  The interest on these loans is accounted for on the cash basis or cost recovery method, until qualifying for return to accrual status.  Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

A loan is considered past due when a payment of principal or interest or both is due but not paid.  Management closely monitors past due loans in timeframes of 30-59 days, 60-89 days, and 90 or more days past due.

These policies apply to all loan portfolio classes and segments.

Substandard and doubtful risk graded commercial, commercial real estate, and construction loans equal to or greater than $100,000 are reviewed for impairment. All troubled debt restructurings, regardless of dollar amount, are also evaluated for impairment. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement.  Factors considered by management in determining impairment and establishing a specific allowance include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due.  Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed.  Impairment is measured on a loan-by-loan basis for commercial, commercial real estate, and construction loans by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

Generally, large groups of smaller balance homogeneous loans (residential real estate and consumer loans) are collectively evaluated for impairment.  The Company's policy for recognizing interest income on impaired loans is consistent with its nonaccrual policy.

The Company's loan portfolio is organized by major segment. These include: commercial, commercial real estate, residential real estate and consumer loans.  Each segment has particular risk characteristics that are specific to the borrower and the generic category of credit.  Commercial loan repayments are highly dependent on cash flows associated with the underlying business and its profitability.  They can also be impacted by changes in collateral values.  Commercial real estate loans share the same general risk characteristics as commercial loans, but are often more dependent on the value of the underlying real estate collateral and, when construction is involved, the ultimate completion of and sale of the project.  Residential real estate loans are generally dependent on the value of collateral and the credit worthiness of the underlying borrower.  Consumer loans are very similar in risk characteristics to residential real estate.

In connection with the MidCarolina and MainStreet mergers, certain loans were acquired which exhibited deteriorated credit quality since origination and for which the Company does not expect to collect all contractual payments.  These purchased credit impaired loans are recorded at the amount paid, such that there is no carryover of the seller's allowance for loan losses.  After acquisition, losses are recognized by an increase in the allowance for loan losses.

Such purchased credit impaired loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as, credit score, loan type, and date of origination.  The Company estimates the amount and timing of expected cash flows for each loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield).  The excess of the loan's or pool's contractual principal and interest over expected cash flows is not recorded (nonaccretable difference).

Over the life of the loan or pool, expected cash flows continue to be estimated.  If the present value of expected cash flows is less than the carrying amount, a loss is recorded as a provision for loan losses.  If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income.

Troubled Debt Restructurings

Troubled Debt Restructurings

In situations where, for economic or legal reasons related to a borrower's financial condition, management may grant a concession to the borrower that it would not otherwise consider, the related loan is classified as a troubled debt restructuring ("TDRs").  Management strives to identify borrowers in financial difficulty early and work with them to modify their loan to more affordable terms before their loan reaches nonaccrual status.  These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral.  In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans.

Allowance for Loan Losses

Allowance for Loan Losses

The purpose of the allowance for loan losses ("ALLL") is to provide for probable losses inherent in the loan portfolio.  The allowance is increased by the provision for loan losses and by recoveries of previously charged-off loans.  Loan charge-offs decrease the allowance.

The goal of the Company is to maintain an appropriate, systematic, and consistently applied process to determine the amounts of the ALLL and the provision for loan loss expense.

The Company uses certain practices to manage its credit risk.  These practices include (1) appropriate lending limits for loan officers, (2) a loan approval process, (3) careful underwriting of loan requests, including analysis of borrowers, cash flows, collateral, and market risks, (4) regular monitoring of the portfolio, including diversification by type and geography, (5) review of loans by the Loan Review department, which operates independently of loan production (the Loan Review function consists of a co-sourced arrangement using both internal personnel and external vendors to provide the Company with a more robust review function of the loan portfolio), (6) regular meetings of the Credit Committees to discuss portfolio and policy changes and make decisions on large or unusual loan requests, and (7) regular meetings of the Asset Quality Committee which reviews the status of individual loans.

Risk grades are assigned as part of the loan origination process. From time to time risk grades may be modified as warranted by the facts and circumstances surrounding the credit.

Calculation and analysis of the allowance for loan losses is prepared quarterly by the Finance Department.  The Company's Credit Committee, Capital Management Committee, Audit Committee, and the Board of Directors review the allowance for adequacy.

The Company's allowance for loan losses has two basic components:  the formula allowance and the specific allowance.  Each of these components is determined based upon estimates and judgments.

The formula allowance uses historical loss experience as an indicator of future losses, along with various qualitative factors, including levels and trends in delinquencies, nonaccrual loans, charge-offs and recoveries, trends in volume and terms of loans, effects of changes in underwriting standards, experience of lending staff, economic conditions, and portfolio concentrations. In the formula allowance for commercial and commercial real estate loans, the historical loss rate is combined with the qualitative factors, resulting in an adjusted loss factor for each risk-grade category of loans.  The period-end balances for each loan risk-grade category are multiplied by the adjusted loss factor.  Allowance calculations for consumer loans are calculated based on historical losses for each product category without regard to risk grade. This loss rate is combined with qualitative factors resulting in an adjusted loss factor for each product category.

The specific allowance uses various techniques to arrive at an estimate of loss for specifically identified impaired loans. These include:

• The present value of expected future cash flows discounted at the loan's effective interest rate.  The effective interest rate on a loan is the rate of return implicit in the loan (that is, the contractual interest rate adjusted for any net deferred loan fees or costs and any premium or discount existing at the origination or acquisition of the loan);

• The loan's observable market price, or

• The fair value of the collateral, net of estimated costs to dispose, if the loan is collateral dependent.

The use of these computed values is inherently subjective and actual losses could be greater or less than the estimates. No single statistic, formula, or measurement determines the adequacy of the allowance.  Management makes subjective and complex judgments about matters that are inherently uncertain, and different amounts would be reported under different conditions or using different assumptions.  For analytical purposes, management allocates a portion of the allowance to specific loan categories and specific loans.  However, the entire allowance is used to absorb credit losses inherent in the loan portfolio, including identified and unidentified losses.

The relationships and ratios used in calculating the allowance, including the qualitative factors, may change from period to period as facts and circumstances evolve.  Furthermore, management cannot provide assurance that in any particular period the Company will not have sizeable credit losses in relation to the amount reserved.  Management may find it necessary to significantly adjust the allowance, considering current factors at the time.

Premises and Equipment

Premises and Equipment

Land is carried at cost.  Premises and equipment are stated at cost, less accumulated depreciation and amortization.  Premises and equipment are depreciated over their estimated useful lives ranging from three years to thirty-nine years; leasehold improvements are amortized over the lives of the respective leases or the estimated useful lives of the improvements, whichever is less.  Software is generally amortized over three years.  Depreciation and amortization are recorded on the straight-line method.

Costs of maintenance and repairs are charged to expense as incurred.  Costs of replacing structural parts of major units are considered individually and are expensed or capitalized as the facts dictate.  Gains and losses on routine dispositions are reflected in current operations.

Goodwill and Intangible Assets

Goodwill and Intangible Assets

Goodwill is subject to at least an annual assessment for impairment by applying a fair value based test.  Additionally, acquired intangible assets (such as core deposit intangibles) are separately recognized if the benefit of the assets can be sold, transferred, licensed, rented, or exchanged, and amortized over their useful lives.  Intangible assets related to branch transactions continued to amortize. The cost of purchased deposit relationships and other intangible assets, based on independent valuation, are being amortized over their estimated lives ranging from eight to ten years.

The Company records as goodwill the excess of purchase price over the fair value of the identifiable net assets acquired. Impairment testing is performed annually, as well as when an event triggering impairment may have occurred. The Company performs its annual analysis as of June 30 each fiscal year. Accounting guidance permits preliminary assessment of qualitative factors to determine whether more substantial impairment testing is required. The Company chose to bypass the preliminary assessment and utilized a two-step process for impairment testing of goodwill. The first step tests for impairment, while the second step, if necessary, measures the impairment.

Trust Assets

Trust Assets

Securities and other property held by the trust and investment services segment in a fiduciary or agency capacity are not assets of the Company and are not included in the accompanying consolidated financial statements.

Other Real Estate Owned

Other Real Estate Owned

Other real estate owned represents real estate that has been acquired through loan foreclosures or deeds received in lieu of loan payments. Generally, such properties are appraised at the time acquired, and are recorded at fair value less estimated selling costs.  Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in noninterest expense.

Bank Owned Life Insurance

Bank Owned Life Insurance

The Company has acquired bank owned life insurance ("BOLI") in connection with three acquisitions. The asset is reflected as the cash surrender value of the policies as provided by the insurer on a monthly basis.

Transfers of Financial Assets

Transfers of Financial Assets

Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company – put presumptively beyond reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.

Income Taxes

Income Taxes

The Company uses the balance sheet method to account for deferred income tax assets and liabilities.  Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws.

When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained.  The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any.  Tax positions taken are not offset or aggregated with other positions.  Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority.  The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination.

Stock-Based Compensation

Stock-Based Compensation

Stock compensation accounting guidance Accounting Standards Codification ("ASC") 718, "Compensation – Stock Compensation" requires that the compensation cost relating to share-based payment transactions be recognized in financial statements.  That cost will be measured based on the grant date fair value of the equity or liability instruments issued.  The stock compensation accounting guidance covers a wide range of share-based compensation arrangements including stock options, restricted share plans, performance-based awards, share appreciation rights, and employee share purchase plans.

The stock compensation accounting guidance requires that compensation cost for all stock awards be calculated and recognized over the employees' service period, generally defined as the vesting period.  For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.  A Black-Scholes model is used to estimate the fair value of stock options, while the market price of the Company's common stock at the date of grant is used for restricted stock awards.

Earnings Per Common Share

Earnings Per Common Share

Basic earnings per common share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share reflect the impact of additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company consist solely of outstanding stock options, and are determined using the treasury method. Nonvested shares of restricted stock are included in the computation of basic earnings per share because the holder has voting rights and shares in non-forfeitable dividends during the vesting period.

Comprehensive Income

Comprehensive Income

Comprehensive income is shown in a two statement approach; the first statement presents total net income and its components followed by a second statement that presents all the components of other comprehensive income such as unrealized gains and losses on available for sale securities and changes in the funded status of a defined benefit postretirement plan.

In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”).  The Company early adopted this new standard in early 2018. ASU 2018-02 requires reclassification from AOCI to retained earnings for "stranded" tax effects resulting from the impact of the newly enacted federal corporate income tax rate on items included in AOCI.

Advertising and Marketing Costs

Advertising and Marketing Costs

Advertising and marketing costs are expensed as incurred, and were $352,000, $260,000, and $356,000 in 2017, 2016, and 2015, respectively.

Mergers and Acquisitions

Mergers and Acquisitions

Business combinations are accounted for under ASC 805, "Business Combinations", using the acquisition method of accounting. The acquisition method of accounting requires an acquirer to recognize the assets acquired and the liabilities assumed at the acquisition date measured at their fair values as of that date. To determine the fair values, the Company relies on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Under the acquisition method of accounting, the Company identifies the acquirer and the closing date and applies applicable recognition principles and conditions. Acquisition-related costs are costs the Company incurs to effect a business combination. Those costs include advisory, legal, accounting, valuation, and other professional or consulting fees. Some other examples of costs to the Company include systems conversions, integration planning consultants and advertising costs. The Company accounts for acquisition-related costs as expenses in the periods in which the costs are incurred and the services are received, with one exception. The costs to issue debt or equity securities is recognized in accordance with other applicable GAAP. These acquisition-related costs have been and will be included within the Consolidated Statements of Income classified within the noninterest expense caption.

Reclassifications

Reclassifications

Certain reclassifications have been made in prior years financial statements to conform to classifications used in the current year.

Use of Estimates

Use of Estimates

In preparing consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, goodwill and intangible assets, unfunded pension liability, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, the valuation of other real estate owned, and the valuation of deferred tax assets and liabilities.

Adoption of New Accounting Standards and Recent Accounting Pronouncements

Recent Accounting Pronouncements

In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The amendments in ASU 2016-01, among other things: (1) requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (2) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (3) Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables); and (4) eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not expect the adoption of ASU 2016-01 to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company has analyzed all leases currently in place and determined the adoption of ASU 2016-02 will not have a material impact on its consolidated financial statements.

During June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The amendments in this ASU are effective for Securities and Exchange Commission ("SEC") filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company has formed a committee to address the adoption of the standard and engaged a third party vendor to assist with the data gathering and analysis. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements.

During August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments", to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The amendments should be applied using a retrospective transition method to each period presented. If retrospective application is impractical for some of the issues addressed by the update, the amendments for those issues would be applied prospectively as of the earliest date practicable.Early adoption is permitted, including adoption in an interim period. The Company does not expect the adoption of ASU 2016-15 to have a material impact on its consolidated financial statements.

During January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business". The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the current implementation guidance in Topic 805, there are three elements of a business - inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a "set") that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this ASU provide a screen to determine when a set is not a business. If the screen is not met, the amendments (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The ASU provides a framework to assist entities in evaluating whether both an input and a substantive process are present. The amendments in this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The amendments in this ASU should be applied prospectively on or after the effective date. No disclosures are required at transition. The Company does not expect the adoption of ASU 2017-01 to have a material impact on its consolidated financial statements.

During January 2017, the FASB issued ASU No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of ASU 2017-04 to have a material impact on its consolidated financial statements.

During March 2017, the FASB issued ASU No. 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The amendments in this ASU require an employer that offers defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715 to report the service cost component of net periodic benefit cost in the same line item(s) as other compensation costs arising from services rendered during the period. The other components of net periodic benefit cost are required to be presented in the income statement separately from the service cost component. If the other components of net periodic benefit cost are not presented on a separate line or lines, the line item(s) used in the income statement must be disclosed. In addition, only the service cost component will be eligible for capitalization as part of an asset, when applicable. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted. The Company does not expect the adoption of ASU 2017-07 to have a material impact on its consolidated financial statements.

During March 2017, the FASB issued ASU No. 2017-08, “Receivables-Nonrefundable Fees and Other Costs (Subtopic 310‐20), Premium Amortization on Purchased Callable Debt Securities.” The amendments in this ASU shorten the amortization period for certain callable debt securities purchased at a premium. Upon adoption of the standard, premiums on these qualifying callable debt securities will be amortized to the earliest call date. Discounts on purchased debt securities will continue to be accreted to maturity. The amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Upon transition, entities should apply the guidance on a modified retrospective basis, with a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption and provide the disclosures required for a change in accounting principle. The Company is currently assessing the impact that ASU 2017-08 will have on its consolidated financial statements.

During May 2017, the FASB issued ASU No. 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting.” The amendments provide guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718.  The amendments are effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued. The Company is currently assessing the impact that ASU 2017-09 will have on its consolidated financial statements.

During August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” The amendments in this ASU modify the designation and measurement guidance for hedge accounting as well as provide for increased transparency regarding the presentation of economic results on both the financial statements and related footnotes. Certain aspects of hedge effectiveness assessments will also be simplified upon implementation of this update. The amendments are effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period. The Company does not expect the adoption of ASU 2017-12 to have a material impact on its consolidated financial statements.

* Except with regard to the Company's and the Bank's leverage capital ratio, includes the current phased-in portion of the Basel III Capital Rules capital conservation buffer which is added to the minimum capital requirements for capital adequacy purposes. The capital conservation buffer requirement began being phased-in effective January 1, 2016, at 0.625% of risk-weighted assets, increasing by the same amount each year until fully implemented at 2.5% on January 1, 2019. The capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of common equity Tier 1 to risk-weighted assets above the minimum but below the conservation buffer will face constraints on dividends, equity repurchases, and compensation based on the amount of the shortfall.
