History and Business

National Bankshares, Inc. (the “Company” or “NBI”) is a financial holding company that was organized in 1986 under the laws of Virginia and is registered under the Bank Holding Company Act of 1956. It conducts most of its operations through its wholly-owned community bank subsidiary, the National Bank of Blacksburg (“NBB”(the “Bank” or “NBB”). It also owns National Bankshares Financial Services, Inc. (“NBFS”), which does business as National Bankshares Insurance Services and National Bankshares Investment Services. References in this report to “we,” “us,” or “our” refer to NBI unless the context indicates that the reference is to NBB.

The National Bank of Blacksburg

The National Bank of Blacksburg, which does business as National Bank, was originally chartered in 1891 as the Bank of Blacksburg. Its state charter was converted to a national charter in 1922 and it became the National Bank of Blacksburg. In 2004, NBB purchased Community National Bank of Pulaski, Virginia. In May, 2006, Bank of Tazewell County, a Virginia bank which since 1996 was a wholly-owned subsidiary of NBI, was merged with and into NBB.

NBB is community-oriented and offers a full range of retail and commercial banking services to individuals, businesses, non-profits and local governments from its headquarters in Blacksburg, Virginia and its twenty-four branch offices throughout southwest Virginia and one loan production office in Roanoke Virginia. NBB has telephone, mobile and internet banking and it operates twenty-four automated teller machines in its service area.

The Bank’s primary source of revenue stems from lending activities.  The Bank focuses lending on small and mid-sized businesses and individuals. Loan types include commercial and agricultural, commercial real estate, construction for commercial and residential properties, residential real estate, home equity and various consumer loan products. The Bank believes its prudent lending policies align its underwriting and portfolio management with its risk tolerance and income strategies. Underwriting and documentation requirements are tailored to the unique characteristics and inherent risks of each loan category.

The Bank’s loan policy is updated and approved by the Board of Directors annually and disseminated to lending and loan portfolio management personnel to ensure consistent lending practices. The policy communicates the Company’s risk tolerance by prescribing underwriting guidelines and procedures, including approval limits and hierarchy, documentation standards, requirements for collateral and loan-to-value limits, debt coverage, overall credit-worthinesscreditworthiness and guarantor support.

Of primary consideration is the repayment ability of the borrowers and (if secured) the collateral value in relation to the principal balance.  Collateral lowers risk and may be used as a secondary source of repayment. The credit decision must be supported by documentation appropriate to the type of loan, including current financial information, income verification or cash flow analysis, tax returns, credit reports, collateral information, guarantor verification, title reports, appraisals (where appropriate) and other documents.  A discussion of underwriting policies and procedures specific to the major loan products follows.

Commercial Loans.  Commercial and agricultural loans primarily finance equipment acquisition, expansion, working capital, and other general business purposes.  Because these loans have a higher degree of risk, the Bank generally obtains collateral such as inventory, accounts receivables or equipment and personal guarantees from the borrowing entity’s principal owners.  The Bank’s policy limits lending up to 60% of the appraised value for inventory, up to 90% of the lower of cost of market value of equipment and up to 70% for accounts receivables less than 90 days old.  Credit decisions are based upon an assessment of the financial capacity of the applicant, including the primary borrower’s ability to repay within proposed terms, a risk assessment, financial strength of guarantors and adequacy of collateral. Credit agency reports of individual owners’ credit history supplement the analysis.

Commercial Real Estate Loans. Commercial mortgages and construction loans are offered to investors, developers and builders primarily within the Bank’s market area in southwest Virginia. These loans generally are secured by first mortgages on real estate. The loan amount is generally limited to 80% of the collateral value and is individually determined based on the property type, quality, location and financial strength of any guarantors. Commercial properties financed include retail centers, office space, hotels and motels, apartments, and industrial properties.

Underwriting decisions are based upon an analysis of the economic viability of the collateral and creditworthiness of the borrower. The Bank obtains appraisals from qualified certified independent appraisers to establish the value of collateral properties. The property’s projected net cash flows compared to the debt service requirement (the(often referred to as the “debt service coverage ratio” or “DSCR”) is required to be 115% or greater and is computed after deduction for a vacancy factor and property expenses, as appropriate. Borrower cash flow may be supplemented by a personal guarantee from the principal(s) of the borrower and guarantees from other parties. The Bank requires title insurance, fire, extended coverage casualty insurance and flood insurance, if appropriate, in order to protect the security interest in the underlying property. In addition, the Bank may employ stress testing techniques on higher balance loans to determine repayment ability in a changing rate environment before granting loan approval.

Public Sector and Industrial Development Loans. The CompanyBank provides both long and short term loans to municipalities and other governmental entities within its geographical footprint. Borrowers include general taxing authorities such as a city or county, 

industrial/economic development authorities or utility authorities. Repayment sources are derived from taxation, such as property taxes and sales taxes, or revenue from the project financed with the loan. The Company’s underwriting considers local economic and population trends, reserves and liabilities, including pension liabilities.

Construction Loans. Construction loans are underwritten against projected cash flows from rental income, business and/or personal income from an owner-occupant or the sale of the property to an end-user. Associated risks may be mitigated by requiring fixed-price construction contracts, performance and payment bonding, controlled disbursements, and pre-sale contracts or pre-lease agreements.

Consumer Real Estate Loans.  The Bank offers a variety of first mortgage and junior lien loans secured by primary residences to individuals within our markets.  Credit decisions are primarily based on loan-to-value (“LTV”) ratios, debt-to-income (“DTI”) ratios, liquidity and net worth.  Income and financial information is obtained from personal tax returns, personal financial statements and employment documentation.  A maximum LTV ratio of 80% is generally required, although higher levels are permitted.  The DTI ratio is limited to 43% of gross income.

Consumer real estate mortgages may have fixed interest rates for the entire term of the loan or variable interest rates subject to change after the first, third, or fifth year.  Variable rates are based on the weekly average yield of United States Treasury Securities and are underwritten at fully-indexed rates. We do not offer certain high risk loan products such as interest-only consumer mortgage loans, hybrid loans, payment option ARMs,adjustable rate mortgages (“ARMs”), reverse mortgage loans, loans with initial teaser rates or any product with negative amortization. Hybrid loans are loans that start out as a fixed rate mortgage, but after a set number of years they automatically adjust to an adjustable rate mortgage.ARM. Payment option ARMs usually have adjustable rates, for which borrowers choose their monthly payment of either a full payment, interest only, or a minimum payment which may be lower than the payment required to reduce the balance of the loan in accordance with the originally underwritten amortization.

Home equity loans are secured primarily by second mortgages on residential property. The underwriting policy for home equity loans generally permits aggregate (the total of all liens secured by the collateral property) borrowing availability up to 80% of the appraised value of the collateral. We offer both fixed rate and variable rate home equity loans, with variable rate loans underwritten at fully-indexed rates. Decisions are primarily based on LTV ratios, DTI ratios, liquidity and credit history. We do not offer home equity loan products with reduced documentation.

Consumer Loans. Consumer loans include loans secured by automobiles, loans to consumers secured by other non-real estate collateral and loans to consumers that are unsecured. Automobile loans include loans secured by new or used automobiles. We originate automobile loans on a direct basis.  During 2018 and years prior, automobile loans were also originated on an indirect basis through selected dealerships.  This program has beenwas discontinued in 2019. We require borrowers to maintain collision insurance on automobiles securing consumer loans. Our procedures for underwriting consumer loans include an assessment of an applicant’s overall financial capacity, including credit history and the ability to meet existing obligations and payments on the proposed loan. An applicant’s creditworthiness is the primary consideration, and if the loan is secured by an automobile or other collateral, the underwriting process also includes a comparison of the value of the collateral security to the proposed loan amount.

Other Products and Services.  Deposit products offered by the Bank include interest-bearing and non-interest bearing demand deposit accounts, money market deposit accounts, savings accounts, certificates of deposit, health savings accounts and individual retirement accounts. Deposit accounts are offered to both individuals and commercial businesses. Business and consumer debit and credit cards are available. NBB offers other miscellaneous services normally provided by commercial banks, such as letters of credit, night depository, safe deposit boxes, utility payment services and automatic funds transfer. NBB conducts a general trust business that has wealth management, trust and estate services for individual and business customers.

At December 31, 2018,2019, NBB had total assets of $1,253,172$1,318,594 and total deposits of $1,052,082.$1,119,961. NBB’s net income for 20182019 was $16,877,$18,011, which produced a return on average assets of 1.35%1.43% and a return on average equity of 9.14%9.82%. Refer to Note 11 of the Notes to Consolidated Financial Statements for NBB’s risk-based capital ratios.

National Bankshares Financial Services, Inc.

In 2001, National Bankshares Financial Services, Inc. was formed in Virginia as a wholly-owned subsidiary of NBI. NBFS offers non-deposit investment products and insurance products for sale to the public. NBFS works cooperatively with Infinex Investments, Inc. to provide investments and with Bankers Insurance, LLC for insurance products. NBFS does not significantly contribute to NBI’s net income.

Operating Revenue

The following table displays components that contributed 15% or more of the Company’s total operating revenue for the years ended December 31, 2019, 2018 2017 and 2016.2017.

Market Area

The Company’s market area in southwest Virginia is made up of the counties of Montgomery, Roanoke, Giles, Pulaski, Tazewell, Wythe, Smyth and Washington. It includes the independent cities of Roanoke, Radford and Galax, and the portions of Carroll and Grayson Counties that are adjacent to Galax. The Company also serves those portions of Mercer County Monroe County and McDowell County, West Virginia that are contiguous with Tazewell County, Virginia and portions of Monroe County, West Virginia that are contiguous with Giles County, Virginia. Although largely rural, the market area is home to two major universities, Virginia TechPolytechnic Institute and State University (“Virginia Tech”) and Radford University, and to three community colleges. Virginia Tech, located in Blacksburg, Virginia, is the area’s largest employer and is the Commonwealth’sVirginia’s second largest university. A second state supported university, Radford University, is located nearby. In recent years, Virginia Tech’s Corporate Research Center has brought a number of technology-related companies to Montgomery County.

In addition to education, the market area has a diverse economic base with manufacturing, agriculture, tourism, healthcare, retail and service industries. Large manufacturing facilities in the region include Celanese Acetate, the largest employer in Giles County, and Volvo Heavy Trucks, the largest company in Pulaski County. Both of these firms have experienced cycles of hiring and layoffs within the past several years. Tazewell County is largely dependent on the coal mining industry and on agriculture for its economic base. Coal production is a cyclical industry that has declined significantly in recent years and suffered from increased regulations. Montgomery County, Bluefield in Tazewell County and Abingdon in Washington County are regional retail centers and have facilities to provide basic health care for the region.

NBI’s market area offers the advantages of a good quality of life, scenic beauty, moderate climate and historical and cultural attractions. The region has had some recent success attracting retirees, particularly from the Northeast and urban northern Virginia.

Because NBI’s market area is economically diverse and includes large public employers, it has historically avoided the most extreme effects of past economic downturns. If the economy wavers or experiences recession, it is likely that unemployment will rise and that other economic indicators will negatively impact the Company's trade area.market.

Competition

The banking and financial services industry in NBI’s market area is highly competitive. The competitive business environment is a result of changes in regulation, changes in technology and product delivery systems and competition from other financial institutions as well as non-traditional financial services. NBB competes for loans and deposits with other commercial banks, credit unions, securities and brokerage companies, mortgage companies, insurance companies, retailers, automobile companies and other nonbank financial service providers. Many of these competitors are much larger in total assets and capitalization, have greater access to capital markets and offer a broader array of financial services than NBB. In order to compete, NBB relies upon a deep knowledge of its markets, a service-based business philosophy, personal relationships with customers, specialized services tailored to meet customers’ needs and the convenience of office locations. In addition, the bankBank is generally competitive with other financial institutions in its market area with respect to interest rates paid on deposit accounts, interest rates charged on loans and other service charges on loans and deposit accounts.

Cybersecurity

As a financial institution, holding company, NBI is subject to cybersecurity risks and has suffered two cybersecurity incidents.  To manage and mitigate cybersecurity risk, the Company limits certain transactions and interactions with customers.  The Company does not offer online account openings or loan originations, limits the dollar amount of online banking transfers to other banks, does not permit customers to submit address changes or wire requests through online banking, requires a special vetting process for commercial customers who wish to originate ACH transfers, and limits certain functionalities of mobile banking.  The Company also requires assurances from key vendors regarding their cybersecurity.  While these measures reduce the likelihood and scope of the risk of further cybersecurity breaches, in light of the evolving sophistication of system intruders, the risk of such breaches continues to exist.  We maintain insurance for these risks but insurance policies are subject to exceptions, exclusions and terms whose applications have not been widely interpreted in litigation.  Accordingly, insurance can provide less than complete protection against the losses that result from cybersecurity breaches and pursuing recovery from insurers can result in significant expense.  In addition, some risks such as reputational damage and loss of customer goodwill, which can result from cybersecurity breaches cannot be insured against.

Organization and Employment

NBI, NBB and NBFS are organized in a holding company/subsidiary structure. At December 31, 2018,2019, NBB had 231235 full time equivalent employees and NBFS had 43 full time employees. NBB performs services and charges commensurate fees to NBI and NBFS.

Regulation, Supervision and Government Policy

NBI and NBB are subject to state and federal banking laws and regulations that provide for general regulatory oversight of all aspects of their operations. As a result of substantial regulatory burdens on banking, financial institutions like NBI and NBB are at a disadvantage to other competitors who are not as highly regulated, and NBI and NBB’s costs of doing business are accordingly higher. Legislative efforts to prevent a repeat of the 2008 financial crisis culminated in the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010.2010 (“the “Dodd-Frank Act”). This legislation, together with existing and planned regulations, dramatically increased the regulatory burden on commercial banks. The burden falls disproportionately on community banks like NBB, which must devote a higher proportion of their human and other resources to compliance than do their larger competitors. The financial crisis also heightened the examination focus by banking regulators, particularly on Bank Secrecy Act, real estate-related assets and commercial loans. However, with the passage of the Economic Growth, Regulatory  Reform and Consumer Protection Act (“EGRRCPA”) in 2018, a number of regulatory requirements for smaller financial institutions like the Company were reduced or eliminated (see below). The following is a brief summary of certain laws, rules and regulations that affect NBI and NBB.

National Bankshares, Inc.

NBI is a bank holding company qualified as a financial holding company under the Federalfederal Bank Holding Company Act of 1956, as amended (“BHCA”), which is administered by the Board of Governors of the Federal Reserve System (the “Federal Reserve”).  As such, NBI is subject to the supervision, examination, and reporting requirements of the BHCA and the regulations of the Federal Reserve. NBI is required to filefurnish to the Federal Reserve an annual report withof its operations at the end of each fiscal year and such additional information as the Federal Reserve and may be required to furnish additional informationrequire pursuant to the BHCA. The Federal Reserve is authorized to examine NBI and its subsidiaries. With some limited exceptions, the BHCA requires a bank holding company to obtain prior approval from the Federal Reserve before acquiring or merging with a bank or before acquiring more than 5% of the voting shares of a bank unless it already controls a majority of shares.

The Bank Holding Company Act. Under the BHCA, a bank holding company is generally prohibited from engaging in nonbanking activities unless the Federal Reserve has found those activities to be incidental to banking. Bank holding companies also may not acquire more than 5% of the voting shares of any company engaged in nonbanking activities. Amendments to the BHCA that were included in the Gramm-Leach-Bliley Act of 1999 (see below) permitted any bank holding company with bank subsidiaries that are well-capitalized, well-managed and which have a satisfactory or better rating under the Community Reinvestment Act (see below) to file an election with the Federal Reserve to become a financial holding company. A financial holding company may engage in any activity that is (i) financial in nature (ii) incidental to a financial activity or (iii) complementary to a financial activity. Financial activities include insurance underwriting, insurance agency activities, securities dealing and underwriting and providing financial, investment or economic advising services. NBI is a financial holding company that currently engages in insurance agency activities and providingprovides financial, investment or economic advising services.

The Virginia Banking Act. The Virginia Banking Act requires all Virginia bank holding companies to register with the Virginia State Corporation Commission (the “Commission”). NBI is required to report to the Commission with respect to its financial condition, operations and management. The Commission may also make examinations of any bank holding company and its subsidiaries and must approve the acquisition of ownership or control of more than 5% of the voting shares of any Virginia bank or bank holding company.

The Gramm-Leach-Bliley Act. The Gramm-Leach-Bliley Act (“GLBA”) permits significant combinations among different sectors of the financial services industry, allows for expansion of financial service activities by bank holding companies and offers financial privacy protections to consumers. GLBA preempts most state laws that prohibit financial holding companies from engaging in insurance activities. GLBA permits affiliations between banks and securities firms in the same holding company structure, and it permits financial holding companies to directly engage in a broad range of securities and merchant banking activities.

The Sarbanes-Oxley Act. The Sarbanes-Oxley Act (“SOX”) protects investors by improving the accuracy and reliability of corporate disclosures. It impacts all companies with securities registered under the Securities Exchange Act of 1934, including NBI. SOX creates increased responsibility for chief executive officers and chief financial officers with respect to the content of filings with the Securities and Exchange Commission. Section 404 of SOX and related Securities and Exchange Commission rules focused increased scrutiny by internal and external auditors on NBI’s systems of internal controls over financial reporting, which is designed to ensure that those internal controls are effective in both design and operation. SOX sets out enhanced requirements for audit committees, including independence and expertise, and it includes stronger requirements for auditor independence and limits the types of non-audit services that auditors can provide. Finally, SOX contains additional and increased civil and criminal penalties for violations of securities laws.

Capital and Related Requirements. In August, 2018, the Federal Reserve updated the Small Bank Holding Company Policy Statement (“the Statement”(the “Statement”), in compliance with the EGRRCPA.  The Statement, among other things, exempts bank holding companies that fall below a certain asset threshold from reporting consolidated regulatory capital ratios and from minimum regulatory capital requirements.  The interim final rule expands the exemption to bank holding companies with consolidated total assets of less than $3 billion. Prior to August 2018, the statement exempted bank holding companies with consolidated total assets of less than $1 billion. As a result of the interim final rule, the Company qualifies as of August, 2018 as a small bank holding company and is no longer subject to regulatory capital requirements on a consolidated basis.

The Bank continues to be subject to various capital requirements administered by banking agencies.agencies as described below. Failure to meet minimum capital requirements can trigger certain mandatory and discretionary actions by regulators that could have a direct material effect on the Company’s consolidated financial statements. The Bank’s capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weightings and other factors.

The regulations require a minimum ratio of certain capital measures. In addition, the Bank is required to maintain a “capital conservation buffer” in excess of the minimum ratio requirements. The implementation period for the capital conservation buffer began in 2016 and will be fully phased in on January 1, 2019. The following table presents the required minimum ratios and minimum ratios with the capital conservation buffer for 2018, as well as the final minimum ratios with the capital conservation buffer when fully phased in:

Risk-weighted assets are assets on the balance sheet as well as certain off-balance sheet items, such as standby letters of credit, to which weights between 0% and 1250% are applied, according to the risk of the asset type. Common Equity Tier 1 Capital (“CET1”) is capital according to the balance sheet, adjusted for goodwill and intangible assets and other prescribed adjustments. At the Company’s election, CET1 is also adjusted to exclude accumulated other comprehensive income. Tier 1 Capital is CET1 adjusted for additional capital deductions. Total Capital is Tier 1 Capital increased for the allowance for loan losses and adjusted for other items. The leverage ratio is the ratio of Tier 1 capital to total average assets, less goodwill and intangibles and certain deferred tax assets.  Pursuant to the EGRRCPA the regulators have proposed a single “Community Bank Leverage Ratio” which would eliminate the four required capital ratios disclosed above for qualifying and electing banks and require the disclosure of a single leverage ratio based on the new Community Capital Leverage Ratio.

NBI is expected to be a source of capital strength for its subsidiary bank, and regulators can undertake a number of enforcement actions against NBI if its subsidiary bank becomes undercapitalized. NBI’s bank subsidiary is well capitalized and fully in compliance with capital guidelines. Failure to meet statutorily mandated capital guidelines or more restrictive ratios separately established for financial institutions could subject NBB or the Company to a variety of enforcement remedies, including issuance of a capital directive, the termination of deposit insurance by the FDIC, a prohibition on accepting or renewing brokered deposits, limitations on the rates of interest that the institution may pay on its deposits and other restrictions on its business. Failure to maintain excess reserves for the capital conservation buffer would limit the ability to make capital distributions and pay discretionary bonuses to executives. As described above, significant additional restrictions can be imposed on NBB if it would fail to meet applicable capital requirements.

Dodd-Frank Wall Street Reform and Consumer Protection Act. The Dodd-Frank Act was signed into law on July 21, 2010. Its wide ranging provisions affect all federal financial regulatory agencies and nearly every aspect of the American financial services industry. The Dodd-Frank Act created an independent Consumer Financial Protection Bureau (“CFPB”(the “CFPB”) which has the ability to write rules for consumer protections governing all financial institutions. All consumer protection responsibility formerly handled by other banking regulators was consolidated in the CFPB. It oversees the enforcement of all federal laws intended to ensure fair access to credit. For smaller financial institutions such as NBI and NBB, the CFPB coordinates its examination activities through their primary regulators.

The Dodd-Frank Act contains provisions designed to reform mortgage lending, which includes the requirement of additional disclosures for consumer mortgages, and the CFPB implemented many mortgage lending regulations to carry out its mandate. Additionally, in response to the Dodd-Frank Act, the Federal Reserve issued rules in 2011 which had the effect of limiting the fees charged to merchants by credit card companies for debit card transactions. The Dodd-Frank Act also contains provisions that affect corporate governance and executive compensation.

The Dodd-Frank Act provisions are extensive and have required the Company and the Bank to deploy resources to comply with them. Several federal agencies, including the Federal Reserve, the CFPB and the Securities and Exchange Commission, have been in the process of issuing final regulations implementing major portions of the legislation, and this process will be affected by the EGRRCPA, which rolls back many provisions of the Dodd-FranDodd-Frank Act (see below).

Source of Strength. Federal Reserve 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 and capital to support NBB, 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.

The Economic Growth, Regulatory Reform and Consumer Protection Act of 2018.In May 2018 the EGRRCPA amended provisions of the Dodd-Frank Act and other statutes administered by banking regulators. Among these amendments are provisions to tailor applicability of certain of the enhanced prudential standards for Systemically Important Financial Institutions (“SIFI’s”) and to increase the $50 billion asset threshold in two stages to $250 billion to which these enhanced standards apply. The ActEGRRCPA exempts insured depositarydepository institutions (and their parent companies) with less than $10 billion in consolidated assets and that meet certain tests from the Volker Rule (which prohibits banks from conducting certain investment activities with their own accounts). As discussed above, thepursuant to EGRRCPA, requires the regulators to promulgate rules establishingfinalized a new Community Bank Leverage Ratio (currently proposed to be 9%)CBLR framework for financial institutions with less than $10 billion in consolidated assets. If the financial institution maintains its tangible equity above the Community Bank Leverage RatioCBLR it will be deemed in compliance with the various regulatory capital requirements currently in effect. The Act increasesEGRRCPA increased the asset threshold from $1 billion to $3 billion for financial institutions to qualify for an 18 month on site examination schedule. The EGRRCPA changes numerous other regulatory requirements based on the size and complexity of financial institutions, particularly benefiting smaller institutions like the Company.

The National Bank of Blacksburg

NBB is a national banking association incorporated under the laws of the United States, and the bank is subject to regulation and examination by the Office of the Comptroller of the Currency (“the OCC”(the “OCC”). NBB’s deposits are insured by the Federal Deposit Insurance Corporation (“the FDIC”(the “FDIC”) up to the limits of applicable law. The OCC, as the primary regulator, and the FDIC regulate and monitor all areas of NBB’s operation. These areas include adequacy of capitalization and loss reserves, loans, deposits, business practices related to the charging and payment of interest, investments, borrowings, payment of dividends, security devices and procedures, establishment of branches, corporate reorganizations and maintenance of books and records. NBB is required to maintain certain capital ratios. It must also prepare quarterly reports on its financial condition for the OCC and conduct an annual audit of its financial affairs. The OCC requires NBB to adopt internal control structures and procedures designed to safeguard assets and monitor and reduce risk exposure. While appropriate for the safety and soundness of banks, these requirements add to overhead expense for NBB and other banks.

The Community Reinvestment Act. NBB is subject to the provisions of the Community Reinvestment Act (“CRA”), which imposes an affirmative obligation on financial institutions to meet the credit needs of the communities they serve, including low and moderate income neighborhoods. The OCC monitors NBB’s compliance with the CRA and assigns public ratings based upon the bank’s performance in meeting stated assessment goals. Unsatisfactory CRA ratings can result in restrictions on bank operations or expansion. NBB received a “satisfactory” rating in its last CRA examination by the OCC.

In December 2019, the FDIC and the OCC jointly proposed rules that would significantly change existing CRA regulations. The proposed rules are intended to increase bank activity in low and moderate income communities where there is significant need for credit, more responsible lending, greater access to banking services, and improvements to critical infrastructure. The proposals change four key areas: (i) clarifying what activities qualify for CRA credit; (ii) updating where activities count for CRA credit; (iii) providing a more transparent and objective method for measuring CRA performance; and (iv) revising CRA-related data collection, record keeping, and reporting.  The Bank is evaluating what impact this proposed rule, if implemented, may have on its operations.

The Gramm-Leach-Bliley ActPrivacy Legislation. In additionSeveral recent laws, including the Right to other consumer privacy provisions,Financial Privacy Act and the Gramm-Leach-Bliley Act (“GLBA”) restrictsGBLA, 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 of customers’ nonpublic personal information. At the inception of the customer relationship and annually thereafter, NBB is requiredinstitutions. A financial institution must provide to provide its customers with information regarding its policies and procedures with respect to the handling of customers’ nonpublic personal information. GLBAEach institution must conduct an internal risk assessment of its ability to protect customer information. These privacy provisions generally prohibitsprohibit a financial institution from providing a customer’s nonpublic personal financial information to unaffiliated third parties without prior notice and approval byfrom the customer.

The USA Patriot Act. The USA Patriot Act (“Patriot Act”) facilitates the sharing of information among government entities and financial institutions to combat terrorism and money laundering. The Patriot Act imposes an obligation on NBB to establish and maintain anti-money laundering policies and procedures, including a customer identification program. The Bank must screen all customers against government lists of known or suspected terrorists. The Patriot Act, particularly as it relates to money laundering, is a significant focus of regulators and there is substantial regulatory oversight to insure compliance.

Consumer Laws and Regulations. There are a number of laws and regulations that regulate banks’ consumer loan and deposit transactions. Among these are the Truth in Lending Act, the Truth in Savings Act, the Expedited Funds Availability Act, the Equal Credit Opportunity Act, the Fair Housing Act, the Fair Credit Reporting Act, the Electronic Funds Transfer Act, the Fair Debt Collections Practices Act, the Home Mortgage Disclosure 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. NBB is required to comply with these laws and regulations in its dealings with customers. In addition, the CFPB has adopted and may continue to refine rules regulating consumer mortgage lending pursuant to the Dodd-Frank Act. There are numerous disclosure and other compliance requirements associated with the consumer laws and regulations. The EGRRCPA modified a number of these requirements, including, for qualifying institutions with less than $10 billion in assets, a safe harbor for compliance with the “ability to pay” requirements for consumer mortgage loans.

Deposit Insurance. NBB has deposits that are insured by the FDIC. The FDIC maintains a Deposit Insurance Fund (“DIF”) that is funded by risk-based insurance premium assessments on insured depository institutions. Assessments are determined based upon several factors, including the level of regulatory capital and the results of regulatory examinations. The FDIC may adjust assessments if the insured institution’s risk profile changes or if the size of the DIF declines in relation to the total amount of insured deposits. Beginning April 1, 2011, an institution’s assessment base became consolidated total assets less its average tangible equity as defined by the FDIC. The FDIC has authority to impose (and has imposed during the recent financial crisis) special measures to boost the deposit insurance fund such as prepayments of assessments and additional special assessments.

After giving primary regulators an opportunity to first take action, FDIC may initiate an enforcement action against any depository institution it determines is engaging in unsafe or unsound actions or which is in an unsound condition, and the FDIC may terminate that institution’s deposit insurance. NBB has no knowledge of any matter that would threaten its FDIC insurance coverage.

Capital Requirements.The NBB is subject to the rules implementing the Basel III capital requirements discussed above with relation to NBI areframework and certain related provisions of the Dodd-Frank Act (the “Basel III Capital Rules”) as applied to NBB by the OCC.  The OCC guidelines provide that banks experiencing internal growth or making acquisitionsBasel III Capital Rules require NBB to comply with minimum capital ratios plus a “capital conservation buffer” designed to absorb losses during periods of economic stress.  The implementation period for the capital conservation buffer began in 2016 and it was fully phased in on January 1, 2019.  The following table presents the required minimum ratios along with the required minimum ratios including the capital conservation buffer:

In addition, implementation of the BASEL III requirements increase required capital minimumsbalance sheet as well as compliance costs duecertain off-balance sheet items, such as standby letters of credit, to their complexity unlesswhich weights between 0% and 1250% are applied, according to the Bank qualifiesrisk of the asset type.  Common Equity Tier 1 Capital (“CET1”) is capital according to the balance sheet, adjusted for goodwill and electsintangible assets and other prescribed adjustments.  At NBB’s election, CET1 is also adjusted to exclude accumulated other comprehensive income.  Tier 1 Capital is CET1 adjusted for additional capital deductions.  Total Capital is Tier 1 Capital increased for the allowance for loan losses and adjusted for other items. The Leverage Ratio is the ratio of Tier 1 Capital to total average assets, less goodwill and intangibles and certain deferred tax assets.  As of December 31, 2019, NBB’s capital ratios exceeded the above minimum ratios including the capital conservation buffer.

NBB is also subject to the “prompt corrective action” regulations pursuant to Section 38 of the Federal Deposit Insurance Act of 1950, which were revised, effective as of January 1, 2015, to incorporate a CET1 ratio and to increase certain other capital ratios. To be classified as well capitalized under the revised regulations, NBB must have the following minimum capital ratios: (i) a CET1 ratio of at least 6.5%; (ii) a Tier 1 Capital to Risk Weighted Assets ratio of at least 8.0%; (iii) a Total Capital to Risk Weighted Assets ratio of at least 10.0%; and (iv) a Leverage Ratio of at least 5.0%.  NBB exceeded the thresholds to be considered well capitalized as of December 31, 2019.

Pursuant to the EGRRCPA regulators have provided for an optional, simplified measure of capital adequacy, which is commonly known as the “community bank leverage ratio” framework (“CBLR”), for qualifying community banking organizations.  Banks that qualify, including NBB, may opt in to the CBLR framework beginning January 1, 2020 or any time thereafter.  The CBLR framework eliminates the requirement to comply with capital ratios disclosed above and, instead, requires the disclosure of a single leverage ratio, with a minimum requirement of 9%.  The Company and the Bank are evaluating whether to opt in to the CBLR framework.

In December 2017, the Basel Committee on Banking Supervision 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 standardized approach for credit risk (including by recalibrating risk weights and introducing new Communitycapital 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 or the Bank. The impact of Basel IV on the Company and the Bank Leverage Ratio discussed above.will depend on the manner in which it is implemented by the federal bank regulatory agencies.

Limits on Dividend Payments. A significant portion of NBI’s income is derived from dividends paid by NBB. As a national bank, NBB may not pay dividends from its capital, and it may not pay dividends if the bank would become undercapitalized, as defined by regulation, after paying the dividend. Without prior OCC approval, NBB’s dividend payments in any calendar year are restricted to the bank’s retained net income for that year, as that term is defined by the laws and regulations, combined with retained net income from the preceding two years, less any required transfer to surplus.

The OCC and FDIC have authority to limit dividends paid by NBB if the payments are determined to be an unsafe and unsound banking practice. Any payment of dividends that depletes the bank’s capital base could be deemed to be an unsafe and unsound banking practice.

Branching. As a national bank, NBB is required to comply with the state branch banking laws of Virginia, the state in which the main office of the bank is located. NBB must also have the prior approval of the OCC to establish a branch or acquire an existing banking operation. Under Virginia law, NBB may open branch offices or acquire existing banks or bank branches anywhere in the state. Virginia law also permits banks domiciled in the state to establish a branch or to acquire an existing bank or branch in another state. The Dodd-Frank Act permits the OCC to approve applications by national banks like NBB to establish de novo branches in any state in which a bank located in that state is permitted to establish a branch.

Ability-to-Repay and Qualified Mortgage Rule. Pursuant to the Dodd-Frank Act, the CFPB amended 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 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) create 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.

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.

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 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, (iv) establish minimum recordkeeping, and (v) mandate disclosures to the appropriate federal banking agency.

The Federal Reserve 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. As of December 31, 2019, the Company had not been made aware of any instances of non-compliance with the final guidance.

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.

Monetary Policy

The monetary and interest rate policies of the Federal Reserve, as well as general economic conditions, affect the business and earnings of NBI. NBB and other banks are particularly sensitive to interest rate fluctuations. The spread between the interest paid on deposits and that which is charged on loans is the most important component of the bank’s earnings. In addition, interest earned on investments held by NBI and NBB has a significant effect on earnings. U.S. fiscal policy, including deficits requiring increased governmental borrowing also can affect interest rates. As conditions change in the national and international economy and in the money markets, the Federal Reserve’s actions, particularly with regard to interest rates, and the effects of fiscal policies can impact loan demand, deposit levels and earnings at NBB. It is not possible to accurately predict the effects on NBI of economic and interest rate changes.

Other Legislative and Regulatory Concerns

Particularly because of uncertain economic conditions and the current political environment, federalFederal and state laws and regulations are regularly proposed that could affect the regulation of financial institutions. New, revised or rescinded regulations could add to the regulatory burden on banks and other financial service providers and increase the costs of compliance, or they could change the products that can be offered and the manner in which financial institutions do business. We cannot foresee how regulation of financial institutions may change in the future and how those changes might affect NBI.

Company Website

Executive Officers of the Company

The following is a list of names and ages of all executive officers of the Company; their terms of office as officers; the positions and offices within the Company held by each officer; and each person’s principal occupation or employment during the past five years.

ItemItem 1A. Risk Factors

If economic trends reverse or recession returns, our credit risk will increase and there could be greater loan losses.

A reversal in economic trends or return to a recession is likely to result in a higher rate of business closures and increased job losses in the region in which we do business. In addition, reduced Statestate funding for the public colleges and universities that are large employers in our market area could have an adverse effect on employment levels and on the area’s economy. These factors would increase the likelihood that more of our customers would become delinquent or default on their loans. A higher level of loan defaults could result in higher loan losses, which could adversely affect our performance.result of operations and financial condition.

A reversal in economic trends, return to recession, or change in interest rates could increase the risk of losses in our investment portfolio.

The Company holds both corporate and municipal bonds in its investment portfolio. A reversal in economic recoverytrends or return to recession could increase the actual or perceived risk of default by both corporate and government issuers and, in either case, could adversely affect the value of these investments. In addition, the value of these investments could be adversely affected by a change in interest rates and related factors, including the pricing of securities.

TheA decline in the condition of the local real estate market could negatively affect our business.

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.security to the Company.  In the event the Company forecloses on a loan that is collateralized with property having reduced market value, the Company may suffer a recovery loss.

Focus on lending to small to mid-sized community-based businesses may increase itsour 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. 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 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 since becoming borrowers of the Bank. 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.

Market interest rates are rising. When market interest rates rise fuchangerther,, our net interest income can be negatively affected in the short term.

The direction and speed of interest rate changes affect our net interest margin and net interest income. In the short term, rising interest rates may negatively affect our net interest income if our interest-bearing liabilities (generally deposits) reprice sooner than our interest-earning assets (generally loans).  Falling interest rates may negatively affect our net interest income if our interest-earning assets reprice sooner than our interest-bearing liabilities.

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 probable 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 regulatory agencies, as an integral part of their examination process, review the Company’s loans and allowance for loan losses. The Company also outsources an independent loan review. While management believes that the allowance for loan losses is adequate to cover current probable 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.

The allowance for loan losses requires management to make significant estimates that affect the financial statements. Due to the inherent nature of this estimate, management cannot provide assurance that it will not significantly increase the allowance for loan losses, which could materially and 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 expects to continue to incur additional losses relating to volatility in nonperforming loans. 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 and restructurings 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 further increases in nonperforming loans in the future.

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.

If more competitors come into our market area,competition increases, our business could suffer.

The financial services industry in our market area is highly competitive, with a number of commercial banks, credit unions, insurance companies, stockbrokers and stockbrokersother nonbank financial service providers seeking to do business with our customers. If there is additional competition from new business or if our existing competitors focus more attention on our market, we could lose customers and our business could suffer.

Additional laws and regulations, or revisions and rescission of existing laws and regulations, could lead to a significant increase in our regulatory burden.

While the risk appears to have diminished somewhat, bothBoth federal and state governments could enact new laws and regulations affecting financial institutions that would further increase our regulatory burden and could negatively affect our profits. Likewise, revisions or rescission of existing laws and regulations already implemented may result in additional compliance costs, at least in the short-termshort term or, if done imprudently, could ultimately create economic risks negatively affecting our revenues.

New laws and regulations could limit our sources of noninterest income.

While the risk appears to have diminished somewhat, new laws and regulations could limit our ability to offer certain profitable products and services. This could have a negative effect on the level of noninterest income.

Intense oversight by regulators could result in stricter requirements and higher overhead costs.

Regulators for the Company and the subsidiary bankBank are tasked with ensuring compliance with applicable laws and regulations.  Laws and regulations are subject to a degree of interpretation.  The regulatory environment has causedIf financial industry regulators to take more extreme interpretations, which could impact the Company’s earnings.earnings could be adversely impacted.

Political, economic and social risks in the U.S. and the rest of the world could negatively affect the financial markets.

Political, economic and social risks in the U.S. and the rest of the world could affect financial markets and affect fiscal policy which could negatively affect our investment portfolio and earnings.

Our information systems may experience an interruption or security breach.

We rely heavily on communications and information systems to conduct our business. Any failure, interruption or breach in security of these systems could result in failures or disruptions of our internet banking, deposit, loan and other systems. While we have policies and procedures designed to prevent or limit the effect of the possible failure, interruption or security breach of our information systems, there can be no assurance that any such failure, interruption or security breach will not occur or, if they doit does occur, that theyit will be adequately addressed.

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 the Company’s operations and business strategy. The Company has invested in acceptedindustry-accepted technologies, and annually reviews its 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 experienced two cyber-intrusions, one in May 2016 and one in January 2017 in which certain customer information was compromised, but which did not cause interruption to the Company’s normal operations.  The Company has implemented additional security measures since the breaches. The Company’s computer systems and infrastructure may in the future 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. The occurrence of any failure, interruption or security breach of our communications and information systems could damage our reputation, result in a loss of customer business, subject us to additional regulatory scrutiny or expose us to civil litigation and possible financial liability.

Cyber-attacks may disarm and/or bypass system safeguards and allow unauthorized access and misappropriation of financial data and assets.

As a financial institution, holding company, we are vulnerable to and the target of cyber-attacks that attempt to access our digital technology systems, disarm and/or bypass system safeguards, access customer data and ultimately increase the risk of economic and reputational loss.

The Company experienced two cyber-intrusions, one in May 2016 and one in January 2017 in which certain customer information was compromised. The Company has strengthened its multi-faceted approach to reduce the exposure of our systems to cyber- intrusions,cyber-intrusions, strengthen our defenses against hackers and protect customer accounts and information relevant to customer accounts from unauthorized access.  These tools include digital technology safeguards, internal policies and procedures, and employee training.

The Company believes its cybersecurity risk management program reasonably addresses the risk from cybersecurity attacks.  However, it is not possible to fully eliminate exposure. We may experience human error or have unknown susceptibilities that allow our systems to become victim to a highly-sophisticated cyber-attack.  If hackers gain entry to our systems, they may disable other safeguards that limit loss, including limits on the number, amount and frequency of ATMautomated teller machine (“ATM”) withdrawals, as well as other loss-prevention or detection measures.

Cybersecurity attacks are probable and may result in additional costs.costs.

The Company has experienced many attempted cybersecurity attacks, of which two resulted in a breach.  The Company estimates that the probability of future attempted cyber-attacks is high.  To reduce the risk of loss from cyber-attacks and to remediate vulnerabilities discovered through the breach investigations, the Company has incurred costs related to forensic investigations, legal and advisory expenses, insurance premiums, system monitoring and testing, and installing new technological infrastructure and defenses.  The Company has implemented every recommendation from the forensic investigations.  If the Company experiences another cyber-breach, these costs will increase as well as potential costs forand the Company will also likely incur additional litigation, reputational harm and regulatory costs.

Insurance may not cover losses from cybersecurity attacks.

The Company has invested in insurance related to cybersecurity. Insurance policies are necessary to protect the Company from major losses but may be written in such a way as to limit the protection from certain risks, including cyber risks for which the availability of insurance coverage is currently limited. If the insurance carrier denies coverage of losses the Company may litigate, resulting in additional legal expense. Because of policy technicalities, litigation may not result in a favorable outcome for the Company.

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, failures 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 and damage the Company’s ability to service its customers, resulting in a loss of customer goodwill. Accordingly, use of such third parties creates an unavoidable inherent risk to the Company’s business operations.

Consumers may increasingly decide not to use the Bank to complete their financial transactions, 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 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.

Changes in funding for higher education could materially affect our business.

Two major employers in the Company’s market area are Virginia Tech and Radford University, both state-supported institutions. If federal or state support for public colleges and universities wanes, our business may be adversely affected from declines in university programs, capital projects, employment, enrollment and other related factors.

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 currently depends on the services of a number of key management personnel. The loss of key personnel could materially and adversely affect the results of operations and financial condition. The Company’s success also depends in part on the ability to attract and retain additional qualified management personnel. Competition for such personnel is strong and the Company may not be successful in attracting or retaining the personnel it requires.

Changes in accounting standards could impact reported earnings. 

The authorities who promulgate accounting standards, including the Financial Accounting Standards Board, SEC, and other regulatory authorities, periodically change the financial accounting and reporting standards that govern the preparation of the Company’s consolidated financial statements. These changes are difficult to predict and can materially impact how the Company records and reports its financial condition and results of operations. In some cases, the Company could be required to apply a new or revised standard retroactively, resulting in the restatement of financial statements for prior periods. Such changes could also require the Company to incur additional personnel or technology costs. Most notably, newNotably, guidance onissued in June 2016 requires a change in the calculation of credit reserves from using an incurred loss model to using the current expected credit losses model (“CECL”). During 2019, the standard’s effective date was finalized in June, 2016. The standard will be effectivedelayed for the Company beginningand other qualifying institutions until January 1, 2020.2023. The Company has formed a management committee to prepare for the new standards.standard. The committee has implemented new data collection measures, researched forecasting resources, studied applicable loss calculations and has begun the process to runrunning preliminary CECL models alongconcurrent with the incurred loss model currentlymodel. The committee will analyze the CECL disclosures of companies who adopt the standard effective January 1, 2020 for consideration in use.further refining its CECL calculations. To implement the new standard, the Company will incur costs related to data collection and documentation, technology, training and increased audit expenses to validate the model. The Company expects that implementationImplementation could significantly impact our required credit reserves. Other impacts to capital levels, profit and loss and various financial metrics will also result.

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.

The Company’s ability to pay dividends depends upon the results of operations of its subsidiaries. 

The Company is a financial holding company and a bank holding company that conducts substantially all of its operations through NBB. As a result, the Company’s ability to make dividend payments on its common stock depends primarily on certain federal regulatory considerations and the receipt of dividends and other distributions from NBB. There are various regulatory restrictions on the ability of NBB to pay dividends or make other payments to the Company. Although the Company has historically paid a cash dividend to the holders of its common stock, holders of the common stock are not entitled to receive dividends, and regulatory or economic factors may cause the Company’s Board of Directors to consider, among other things, the reduction of dividends paid on the Company’s common stock.

While the Company’s common stock is currently traded on the NASDAQNasdaq Capital 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 NASDAQNasdaq Capital Market has been relatively low when compared with larger companies listed on the NASDAQNasdaq Capital 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, stockholders may not be able to sell a substantial number of shares for the same price at which stockholders could sell a smaller number of shares. In addition, the Company cannot predict the effect, if any, that future sales of its 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. Sales of substantial amounts of common stock in the market, or the potential for large amounts of sales in the market, could cause the price of the Company’s common stock to decline, or reduce the Company’s ability to raise capital through future sales of common stock.

The Company’s liquidity needs could adversely affect results of operations and financial condition.

The Company’s primary sources of funds are deposits and loan repayments. While scheduled loan repayments are a relatively stable source of funds, they are subject to the ability of borrowers to repay the loans. The ability of borrowers to repay loans can be adversely affected by a number of factors, including, but not limited to, changes in economic conditions, reductions in real estate values or markets, availability of, and/or access to, sources of refinancing, business closings or lay-offs, and natural disasters. Additionally, deposit levels may be affected by a number of factors, including, but not limited to, rates paid by competitors, general interest rate levels, regulatory capital requirements, returns available to customers on alternative investments and general economic conditions. Accordingly, the Company may be required from time to time to rely on secondary sources of liquidity to meet withdrawal demands or otherwise fund operations. Such sources include Federal Home Loan Bank of Atlanta (“FHLB”) advances, sales of securities and loans, federal funds lines of credit from correspondent banks and borrowings from the Federal Reserve Discount Window, as well as additional out-of-market time deposits and brokered deposits. While the Company believes that these sources are currently adequate, there can be no assurance they will be sufficient to meet future liquidity demands, particularly if the Company continues to grow and experiences increasing loan demand. The Company may be required to slow or discontinue loan growth, capital expenditures or other investments or liquidate assets should such sources not be adequate.

Natural disasters, acts of war or terrorism, the impact of health epidemics and other adverse external events could detrimentally affect our financial condition and results of operations. 

Natural disasters, acts of war or terrorism, and other adverse external events could have a significant negative impact on our ability to conduct business or upon third parties who perform operational services for us or our customers.  Such events also could affect the stability of our deposit base, impair the ability of borrowers to repay outstanding loans, impair the value of collateral securing loans, cause significant property damage, result in lost revenue or cause us to incur additional expenses.

The recent coronavirus outbreak could negatively impact the ability of our employees and customers to engage in banking and other financial transactions in the geographic areas in which the Company operates. The Company also could be adversely affected if key personnel or a significant number of employees were to become unavailable due to a coronavirus outbreak in our market areas. Although the Company has business continuity plans and other safeguards in place, there is no assurance that such plans and safeguards will be effective.  In the event of a natural disaster, the spread of the coronavirus to our market areas or other adverse external events, our business, services, asset quality, financial condition and results of operations could be adversely affected.

The effects of widespread public health emergencies may negatively affect our local economies or disrupt our operations, which would have an adverse effect on our business or results of operations.

Widespread health emergencies, such as the recent coronavirus outbreak, can disrupt our operations through their impact on our employees, customers and their businesses, and the communities in which we operate. Disruptions to our customers could result in increased risk of delinquencies, defaults, foreclosures and losses on our loans, negatively impact regional economic conditions, result in a decline in local loan demand, loan originations and deposit availability and negatively impact the implementation of our growth strategy. Any one or more of these developments could have a material adverse effect on our business, financial condition and results of operations.

ItemItem 1B. Unresolved Staff Comments

There are no unresolved staff comments.

ItemItem 2. Properties

NBB owns and has a branch bank in NBI’s headquarters building located at 101 Hubbard Street, Blacksburg, Virginia. NBB’s main office is at 100 South Main Street, Blacksburg, Virginia. NBB owns an additional seventeen branch offices and it leases six branch locations and a loan production office. We believe that existing facilities are adequate for current needs and to meet anticipated growth.

If the national economy or the Company’s market area experience a downturn, it is likely that unemployment will rise and that other economic indicators will negatively impact the Company’s trade area. Because of the importance to the Company’s markets of state-funded universities, cutbacks in the funding provided by the Commonwealth could also negatively impact employment. This could lead to a higher rate of delinquent loans and a greater number of real estate foreclosures. Higher unemployment and the fear of layoffs causes reduced consumer demand for goods and services, which negatively impacts the Company’s business and professional customers. An economic downturn could have an adverse effect on all financial institutions, including the Company.

Non-GAAP Financial Measures

This report refers toThe Company prepares financial information in accordance with accounting principles generally accepted in the United States (“GAAP”), with the exception of certain financial measures thatwhich are computed under a basis other than GAAP (“non-GAAP”), including.  These measures include the efficiency ratio, the net interest margin and the noninterest margin.

The efficiency ratio is computed by dividing noninterest expense, excluding the write-down of insurance receivable, by the sum of net interest income on a tax-equivalent basis and noninterest income. The tax rate used to calculate fully taxable equivalent basis is 21% in 2018 and 35% in 2017 and years prior. 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 U.S. generally accepted accounting principles (GAAP) and should not be construed as such.  Management believes 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 efficiency ratio is computed by dividing noninterest expense, excluding certain items management deems unusual or non-recurring, by the sum of net interest income on a tax-equivalent basis and noninterest income, excluding certain items management deems unusual or non-recurring. The tax rate used to calculate fully taxable equivalent basis is 21% in 2019 and 2018 and 35% in 2017.  This is a non-GAAP financial measure that the Company believes provides investors with important information regarding operational efficiency. The components of the efficiency ratio calculation are summarized in the following table.

The net interest margin is calculated by dividing taxable 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 2019 and 2018 is 21% and 35% for 2017 and years prior.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.

The noninterest margin is calculated by dividing noninterest expense (excluding the write-down of insurance receivable) less noninterest income (excluding realized securities gain/loss, net) by average year-to-date assets. The reconciliation of adjusted noninterest income and adjusted noninterest expense, which are not measurements under GAAP, is reflected in the table below.

Critical Accounting Policies

General

The Company’s financial statements are prepared in accordance with accounting principles generally accepted in the United States (GAAP).GAAP. The financial information contained within our statements is, to a significant extent, financial information based on measures of the financial effects of transactions and events that have already occurred. A variety of factors could affect the ultimate value obtained when earning income, recognizing an expense, recovering an asset or relieving a liability. Although the economics of the Company’s transactions may not change, the timing of events that would impact the transactions could change.

Allowance for Loan Losses

The allowance for loan losses is an estimate of probable losses inherent in our loan portfolio. The allowance is funded by the provision for loan losses, reduced by charge-offs of loans and increased by recoveries of previously charged-off loans. The determination of the allowance is based on two accounting principles, Accounting Standards Codification (“ASC”) Topic 450-20 (Contingencies) which requires that losses be accrued when occurrence is probable and the amount of the loss is reasonably estimable, and ASC Topic 310-10 (Receivables) which requires accrual of losses on impaired loans if the recorded investment exceeds fair value.

Probable losses are accrued through two calculations, individual evaluation of impaired loans and collective evaluation of the remainder of the portfolio. Impaired loans are larger non-homogeneous loans for which there is a probability that collection will not occur according to the loan terms, as well as loans whose terms have been modified in a troubled debt restructuring.restructuring (“TDRs”). Impaired loans that are not TDR’sTDRs with an estimated impairment loss are placed on nonaccrual status. TDR’sTDRs with an impairment loss may accrue interest if they have demonstrated six months of timely payment performance.

Impaired loans

Impaired loans are identified through the Company’s credit risk rating process. Estimated loss for an impaired loan is the amount of recorded investment that exceeds the loan’s fair value. Fair value of an impaired loan is measured by one of three methods: the fair value of collateral (“collateral method”), the present value of future cash flows (“cash flow method”), or observable market price. The Company applies the collateral method to collateral-dependent loans, loans for which foreclosure is imminent and to loans for which the fair value of collateral is a more reliable estimate of fair value. The cash flow method is applied to loans that are not collateral dependent and for which cash flows may be estimated.

The Company bases collateral method fair valuation upon the “as-is” value of independent appraisals or evaluations. Valuations for impaired loans secured by residential 1-4 family properties with outstanding principal balances greater than $250 are based on an appraisal. Appraisals are also used to value impaired loans secured by commercial real estate with outstanding principal balances greater than $500. Collateral-method impaired loans secured by residential 1-4 family property with outstanding principal balances of $250 or less, or secured by commercial real estate with outstanding principal balances of $500 or less, are valued using an internal evaluation.

Appraisals and internal valuations provide an estimate of market value. Appraisals must conform to the Uniform Standards of Professional Appraisal Practice (“USPAP”) and are prepared by an independent third-party appraiser who is certified and licensed and who is approved by the Company. Appraisals may incorporate market analysis, comparable sales analysis, cash flow analysis and market data pertinent to the property to determine market value.

Internal evaluations are prepared by third party providers and reviewed by employees of the Company who are independent of the loan origination, operation, management and collection functions. Evaluations provide a property’s market value based on the property’s current physical condition and characteristics and the economic market conditions that affect the collateral’s market value. Evaluations incorporate multiple sources of data to arrive at a property’s market value, including physical inspection, independent third-party automated tools, comparable sales analysis and local market information.

Updated appraisals or evaluations are ordered when the loan becomes impaired if the appraisal or evaluation on file is more than twenty-four months old. Appraisals and evaluations are reviewed for propriety and reasonableness and may be discounted if the Company determines that the value exceeds reasonable levels. If an updated appraisal or evaluation has been ordered but has not been received by a reporting date, the fair value may be based on the most recent available appraisal or evaluation, discounted for age.

The appraisal or evaluation value for a collateral-dependent loan for which recovery is expected solely from the sale of collateral is reduced by estimated selling costs. Estimated losses on collateral-dependent loans, as well as any other impairment loss considered uncollectible, are charged against the allowance for loan losses. Impairment losses that are not considered uncollectible or for loans that are not collateral dependent are accrued in the allowance. Impaired loans with partial charge-offs are maintained as impaired until the remaining balance is satisfied. Smaller homogeneous impaired loans that are not troubled debt restructurings and are not part of a larger impaired relationship are collectively evaluated.

Troubled debt restructuringsTDRs are impaired loans and are measured for impairment under the same valuation methods as other impaired loans. Troubled debt restructuringsTDRs are maintained in nonaccrual status until the loan has demonstrated reasonable assurance of repayment with at least six months of consecutive timely payment performance. Troubled debt restructuringsTDRs may be removed from TDR status, and therefore from individual evaluation, if the restructuring agreement specifies a contractual interest rate that is a market interest rate at the time of restructuring and the loan is in compliance with its modified terms one year after the restructure was completed.

Collectively-evaluated loans

Non-impaired loans and smaller homogeneous impaired loans that are not troubled debt restructuringsTDRs and not part of a larger impaired relationship are grouped by portfolio segments. Portfolio segments are further divided into smaller loan classes. Loans within a segment or class have similar risk characteristics.

Probable loss is determined by applying historical net charge-off rates as well as additional percentages for trends and current levels of quantitative and qualitative factors. Loss rates are calculated for and applied to individual classes by averaging loss rates over the most recent 8eight quarters. The look-back period of 8eight quarters is applied consistently among all classes.

Two loss rates for each class are calculated: total net charge-offs for the class as a percentage of average class loan balance (“class loss rate”), and total net charge-offs for the class as a percentage of average classified loans in the class (“classified loss rate”). Classified loans are those with risk ratings that indicate credit quality is “substandard”, “doubtful” or “loss”. Net charge-offs in both calculations include charge-offs and recoveries of classified and non-classified loans as well as those associated with impaired loans. Class historical loss rates are applied to collectively-evaluated non-classified loan balances, and classified historical loss rates are applied to collectively-evaluated classified loan balances.

Qualitative factors are evaluated and allocations are applied to each class. Qualitative factors include delinquency rates, loan quality and concentrations, loan officers’ experience, changes in lending policies and changes in the loan review process. Economic factors such as unemployment rates, bankruptcy rates and others are evaluated, with standard allocations applied consistently to relevant classes.

The Company accrues additional allocations for criticized loans within each class and for loans designated high risk. Criticized loans include classified loans as well as loans rated “special mention”. Loans rated special mention indicate weakened credit quality but to a lesser degree than classified loans. High risk loans are defined as junior lien mortgages, loans with high loan-to-value ratios and loans with terms that require interest only payments. Both criticized loans and high risk loans are included in the base risk analysis for each class and are allocated additional reserves.

Estimation of the allowance for loan losses

The estimation of the allowance involves analysis of internal and external variables, methodologies, assumptions and our judgment and experience. Key judgments used in determining the allowance for loan losses include internal risk rating determinations, market and collateral values, discount rates, loss rates, and our view of current economic conditions. These judgments are inherently subjective and our actual losses could be greater or less than the estimate. Future estimates of the allowance could increase or decrease based on changes in the financial condition of individual borrowers, concentrations of various types of loans, economic conditions or the markets in which collateral may be sold. The estimate of the allowance accrual determines the amount of provision expense and directly affects our financial results.

The estimate of the allowance for December 31, 20182019 considered market and portfolio conditions during 20182019 as well as the levels of delinquencies and net charge-offs in the eight quarters prior to the quarter ended December 31, 2018.2019. If the economy experiences a downturn, the ultimate amount of loss could vary from that estimate. For additional discussion of the allowance, see Note 5 to the consolidated financial statements and “Asset Quality,” and “Provision and Allowance for Loan Losses.”

Goodwill

Goodwill is subject to at least an annual assessment for impairment by applying a fair value based test. The Company performs impairment testing in the fourth quarter of each year. The Company’s most recent impairment test was performed using data from September 30, 2018.2019. Accounting guidance provides the option of performing preliminary assessment of qualitative factors before performing more substantial testing for impairment. The Company opted not to perform the preliminary assessment. The Company’s goodwill impairment analysis considered three valuation techniques appropriate to the measurement. The first technique uses the Company’s market capitalization as an estimate of fair value; the second technique estimates fair value using current market pricing multiples for companies comparable to the Company; while the third technique uses current market pricing multiples for change-of-control transactions involving companies comparable to the Company. Each measure indicated that the Company’s fair value exceeded its book value, validating that goodwill is not impaired.

Certain key judgments were used in the valuation measurement. Goodwill is held by the Company’s bank subsidiary. The bank subsidiary is 100% owned by the Company, and no market capitalization is available. Because most of the Company’s assets are comprised of the subsidiary bank’s equity, the Company’s market capitalization was used to estimate the Bank’s market capitalization. Other judgments include the assumption that the companies and transactions used as comparables for the second and third technique were appropriate to the estimate of the Company’s fair value, and that the comparable multiples are appropriate indicators of fair value, and compliant with accounting guidance.

Other Real Estate Owned (“OREO”)

Real estate acquired through, or in lieu of, foreclosure is held for sale and is stated at fair value of the property, less estimated disposal costs, if any. Any excess of cost over the fair value less costs to sell at the time of acquisition is charged to the allowance for loan losses. The fair value is reviewed periodically by management and any write-downs are charged against current earnings. Accounting policy and treatment is consistent with accounting for impaired loans described above.

Pension Plan

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 estimated return on plan assets and the anticipated rate of compensation 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.

Other Than Temporary Impairment ("OTTI") of Securities (“OTTI”)

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) the Company intends to sell the security or (ii) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis.  If, however, the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security before recovery, the Company 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.OTTI.  If there is a credit loss, other-than-temporary impairmentOTTI exists, and the credit loss must be recognized in net income and the remaining portion of impairment must be recognized in other comprehensive income (loss).  The Company regularly reviews each investment security for other-than-temporary impairmentOTTI based on criteria that include the extent to which cost exceeds market price, the duration of that market decline, the financial health of and specific prospects for the issuer, the Company’s best estimate of the present value of cash flows expected to be collected from debt securities, the Company’s intention with regard to holding the security to maturity and the likelihood that the Company would be required to sell the security before recovery.

Asset Quality

Key indicators of NBI’s asset quality are presented in the following table:

The Company monitors asset quality indicators in managing credit risk and in determining the allowance and provision for loan losses. At December 31, 2018,2019, nonperforming loans were $3,420$3,375 or 0.48%0.46% of loans net of unearned income and deferred fees and costs. This compares to $2,769$3,420 or 0.41%0.48% at December 31, 2017.2018. Loans past due 90 days or more and still accruing at year-end 20182019 totaled $35, a decrease$231, an increase from $51$35 at December 31, 2017.2018.  The net charge-off ratio decreasedincreased from 0.08% for the year ended December 31, 2017 to 0.07% for the year ended December 31, 2018 to 0.09% for the year ended December 31, 2019, while other real estate ownedOREO decreased $765$440 for the same period.

The Company’s risk analysis determined an allowance for loan losses of $7,390$6,863 at December 31, 2018,2019, resulting in a recoveryprovision for the year of $81.$126. This compares with an allowance for loan losses of $7,925$7,390 as of December 31, 2017,2018, and a provisionrecovery of $157$81 for the year ended December 31, 2017.2018. The ratio of the allowance for loan losses to loans decreased to 1.04%,0.94% at December 31, 2019, from 1.19%1.04% at December 31, 2018. The methodology for determining the allowance for loan losses relies on historical charge-off trends, modified by trends in nonperforming loans and economic indicators. More information about the level and calculation methodology of the allowance for loan losses is provided in “Provision and Allowance for Loan Losses”,  “Balance Sheet – Loans – Risk Elements,” “Balance Sheet – Loans – Troubled Debt Restructurings,” as well as Notes 1 and 5 of the Notes to the financial statements.Consolidated Financial Statements.

Sufficient resources have been dedicated to working out problem assets, and exposure to loss is somewhat mitigated because most of the nonperforming loans are collateralized. More information about nonaccrual and past due loans is provided in “Balance Sheet – Loans – Risk Elements” and Note 5 of the Notes to the financial statements.Consolidated Financial Statements. The Company continues to monitor risk levels within the loan portfolio and expects that any further increase in the allowance for loan losses would be the result of the refinement of loss estimates and would not dramatically affect net income.

Net Interest Income

Net interest income was $37,767 for the year ended December 31, 2019, $38,177 for the year ended December 31, 2018 was $38,177, an increase of $1,042, or 2.81%, when compared toand $37,135 for the prior year.year ended December 31, 2017. The net interest margin was 3.29% for 2019, 3.36% for 2018 was 3.36%, compared toand 3.45% for 2017.  Total interest income was $45,147 for the periodyear ended December 31, 2019, $43,224 for the year ended December 31, 2018 was $43,224, an increase of $1,964 fromand $41,260 for the periodyear ended December 31, 2017. Interest expense increased by $922 duringwas $7,380 for the same time frame, fromyear ended December 31, 2019, $5,047 for the year ended December 31, 2018 and $4,125 for the year ended December 31, 20172017.

The amount of net interest income earned is affected by various factors, including changes in market interest rates due to $5,047 forthe Federal Reserve‘s monetary policy, U.S. fiscal policy, competitive pressure, the level and composition of the interest-earning assets and the composition of interest-bearing liabilities.

The Federal Reserve increased its target federal funds rate by 25 basis points in March, June, September and December, 2018 and then decreased the rate by 25 basis points in July, September, and October 2019, ending the year ended December 31, 2018.at a target of 1.75%.  Changes in the Federal Reserve’s target interest rate immediately impact the yield on the Company’s interest-bearing deposits in other banks, and have a slightly delayed impact on other interest-earning assets. The Federal Reserve’s target interest rate also impacts the Company’s cost of interest-bearing liabilities.

The primary source of funds used to support the Company’s interest-earning assets is deposits. Deposits are obtained in the Company’s market through traditional marketing techniques. The cost of deposits is dependent on interest rate levels and competitive factors.  Increases in the Federal Reserve’s target interest rate may increase competitive pressure to raise deposit offering rates, while decreases in the Federal Reserve’s target interest rate allow reduced deposit offering rates.  Time deposits provide a measure of stability in the cost of funds, but partially delay the Company’s ability to respond to downward rate movements. The Company also has access to other funding sources, including the FHLB. 

Interest expense came about in 2019 was influenced by increased deposit offering rates in the latter part because of deposit pricing increases2018 that carried in to 2019 and were required to remain competitive in what was a rising interest rate environment.  The Company also engagedInterest expense in 2018 included the cost of short-term borrowings during 2018 to meet loan demand while anticipating maturity of securities and an increase in deposits that is typical during the fourth quarter. Please refer to the section titled “Analysis of Changes In Interest Income and Interest Expense” for further information related to rate and volume changes.

The amount of net interest income earnedmargin is affected by various factors,a non-GAAP measure that incorporates the effect of tax-advantaged instruments, including changes in market interest rates duequalifying investments and loans to the Federal Reserve Board’s monetary policy, U.S. fiscal policy, the level and compositionmunicipalities.  For purposes of the earning assetsnet interest margin, interest income on tax-advantaged instruments is grossed up to reflect the value of lower tax expense.  The Tax Act became effective January 1, 2018 and decreased the compositionCompany’s tax rate from a marginal 35% in 2017 to a flat 21% in 2018 and 2019.  This decreased the value of interest-bearing liabilities. The Companytax-advantaged instruments when 2019 and 2018 are compared with 2017.

Management has the ability to respond over time to interest rate movements, statutory tax rate changes and other influencing factors to reduce volatility in the net interest margin. However, the frequency and/or magnitude of changes in market interest rates and legislative changes are difficult to predict and may have a greater impact on net interest income than adjustments by management.

The Federal Reserve increased its target federal funds rate by 25 basis points in December 2017 and raised rates by 25 basis points again in March, June, September and December, 2018, ending the year at a target of 2.50%. The rate increases positively affected the yield on the Company’s interest-bearing deposits in other banks and taxable securities for 2018. The yield on interest-bearing deposits increased from 1.10% for 2017 to 1.84% for 2018 and the yield on taxable securities increased from 1.82% for 2017 to 2.07% for 2018. The rate increases also positively affected the yield on loans, but was offset by the decline in the Company’s tax rate. The Tax Cuts and Jobs Act became effective January 1, 2018 and decreased the Company’s tax rate from a marginal 35% to a flat 21%.
