Item 1. Business

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”). It also owns National Bankshares Financial Services, Inc. (“NBFS”), which does business as National Bankshares Insurance Services and National Bankshares Investment Services.

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 had also been 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-five branch offices throughout southwest Virginia. NBB has telephone and internet banking and it operates twenty-five automated teller machines in its service area.

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. Each loan category requires underwriting and documentation suited to unique characteristics and inherent risks.

The Bank’s loan policy is updated and approved by the Board of Directors annually, and disseminated throughout the Bank 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 and overall credit-worthiness, 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 inventories, accounts receivables or equipment, and personal guarantees from the borrowing entity’s principal owners. The Bank’s policy limits lending to 60% of the appraised value for inventory and 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 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 are predominantly non-residential in nature, and include retail centers, 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 “debt service coverage ratio” or “DSC” ratio) is required to be 110% 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, and 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.

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.

3

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 with mortgage insurance. 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 yearly 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 interest-only consumer mortgage loans, sub-prime loans, or any variation on subprime lending including hybrid loans and payment option ARMs, or any product with negative amortization. Sub-prime loans involve extending credit to borrowers who exhibit characteristics indicating a significantly higher risk of default than traditional bank lending customers. 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. 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.

Automobile loans include loans secured by new or used automobiles. We originate automobile loans either on a direct basis or on an indirect basis through selected dealerships. We require borrowers to maintain collision insurance on automobiles securing consumer loans. Our procedures for underwriting automobile 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. Although an applicant’s creditworthiness is the primary consideration, 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. Merchant credit card services and 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, travelers checks, utility payment services and automatic funds transfer. NBB conducts a general trust business that has wealth management, and trust and estate services for individual and business customers.

At December 31, 2015, NBB had total assets of $1,197,804 and total deposits of $1,019,268. NBB’s net income for 2015 was $16,229, which produced a return on average assets of 1.41% and a return on average equity of 9.54%. Refer to Note 12 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.

Market Area

The Company’s market area in southwest Virginia is made up of the counties of Montgomery, Giles, Pulaski, Tazewell, Wythe, Smyth and Washington. It includes the independent cities of 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 and McDowell County, West Virginia that are contiguous with Tazewell County, Virginia. Although largely rural, the market area is home to two major universities, 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’s second largest university. A second state supported university, Radford University, is located nearby. State support for public colleges and universities, like Virginia Tech and Radford University, has been adversely affected by the recession and State budget considerations. 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 all represented. 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. Pulaski and Galax have in the past been centers for furniture manufacturing. However, this industry has been declining because of growing furniture imports and the loss of demand. Several furniture companies have gone out of business in the recent past. Tazewell County is largely dependent on the coal mining industry and on agriculture for its economic base. Coal production is a cyclical industry that was negatively affected by the economic decline. 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 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 economic recovery wavers or reverses, it is likely that unemployment will rise and that other economic indicators will negatively impact the Company's trade area.

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 bank 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.

Organization and Employment

NBI, NBB and NBFS are organized in a holding company/subsidiary structure. Functions that serve both subsidiaries, including audit, compliance, loan review and human resources, are at the holding company level, and fees are charged to the respective subsidiary for those services.

At December 31, 2015, NBI employed 19 full time employees, NBB had 202 full time equivalent employees and NBFS had 4 full time equivalent employees.

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 Act of 2010. This legislation, together with existing and planned regulations, has 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 has also heightened the examination focus by banking regulators, particularly on real estate related assets and commercial loans. In the current environment, the potential for additional laws and regulations that will impact the Company, as well as heightened examination standards with regard to asset quality, cannot be ruled out. The following is a brief summary of certain laws, rules and regulations that affect NBI and NBB.

5

National Bankshares, Inc.

NBI is a bank holding company qualified as a financial holding company under the Federal Bank Holding Company Act (BHCA), which is administered by the Board of Governors of the Federal Reserve System (the “Federal Reserve”). NBI is required to file an annual report with the Federal Reserve and may be required to furnish additional information 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 providing 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 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”) enacted major reforms of the federal securities laws intended to protect 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 insure 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. The Federal Reserve has adopted risk-based capital guidelines that are applicable to NBI. The guidelines provide that the Company must maintain a minimum ratio of 8% of qualified total capital to risk-weighted assets (including certain off-balance sheet items, such as standby letters of credit) and a minimum ratio of Tier 1 capital to risk-weighted assets of 6%. In addition, the Federal Reserve has established minimum leverage ratio guidelines of 4% for banks that meet certain specified criteria. The leverage ratio is the ratio of Tier 1 capital to total average assets, less intangibles. 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.  

On July 2, 2013, the Federal Reserve voted to adopt final Basel III capital rules for U.S. banking organizations. The final rules establish an integrated regulatory capital framework and will implement in the United States the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision and certain changes required by the Dodd-Frank Act. Under the final rule, minimum requirements will increase for both the quantity and quality of capital held by banking organizations. Consistent with the international Basel framework, the final rule includes a new minimum ratio of common equity tier 1 capital (Tier I Common) to risk-weighted assets and a common equity tier 1 capital conservation buffer of 2.5% of risk-weighted assets that will apply to all supervised financial institutions. The rule also raises the minimum ratio of tier 1 capital to risk-weighted assets and includes a minimum leverage ratio of 4% for all banking organizations. These new minimum capital ratios became effective for the Company on January 1, 2015 and will be fully phased-in on January 1, 2019.

6

The final rule emphasizes common equity tier 1 capital, the most loss-absorbing form of capital, and implements strict eligibility criteria for regulatory capital instruments. The final rule also improves the methodology for calculating risk-weighted assets to enhance risk sensitivity. Banks and regulators use risk weighting to assign different levels of risk to different classes of assets. We are in the process of evaluating the impact of the Basel III final rule on the Company’s regulatory capital ratios.

Failure to meet statutorily mandated capital guidelines or more restrictive ratios separately established for a financial institution 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. 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. Among the provisions of the Dodd-Frank Act that directly impact the Company is the creation of an independent Consumer Financial Protection Bureau (“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 is 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 will coordinate 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. The CFPB has begun implementing mortgage lending regulations to carry out its mandate. In addition, the Federal Reserve issued new rules, effective October 1, 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.

Although the Dodd-Frank Act provisions themselves are extensive, the ultimate impact on the Company of this massive legislation is unknown. The Act provides that several federal agencies, including the Federal Reserve, the CFPB and the Securities and Exchange Commission, shall issue regulations implementing major portions of the legislation, and this process is ongoing.

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 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 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 (“OCC”). NBB’s deposits are insured by the Federal Deposit Insurance Corporation (“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. 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.

7

The Gramm-Leach-Bliley Act. In addition to other consumer privacy provisions, the Gramm-Leach-Bliley Act (“GLBA”) restricts the use by financial institutions of customers’ nonpublic personal information. At the inception of the customer relationship and annually thereafter, NBB is required to provide its customers with information regarding its policies and procedures with respect to handling of customers’ nonpublic personal information. GLBA generally prohibits a financial institution from providing a customer’s nonpublic personal information to unaffiliated third parties without prior notice and approval by 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 is also required to screen all customers against government lists of known or suspected terrorists. There is additional regulatory oversight to insure compliance with the Patriot Act.

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 and the Service Members Civil Relief Act. NBB is required to comply with these laws and regulations in its dealings with customers. In addition, the CFPB has begun adopting 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.

Deposit Insurance. NBB has deposits that are insured by the FDIC. 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. 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 same capital requirements that are discussed above with relation to NBI are applied to NBB by the OCC. The OCC guidelines provide that banks experiencing internal growth or making acquisitions are expected to maintain strong capital positions well above minimum levels, without reliance on intangible assets. In addition, implementation of the BASEL III requirements could increase required capital minimums as well as compliance costs due to their complexity.

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

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. 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, 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, federal and state laws and regulations are regularly proposed that could affect the regulation of financial institutions. New 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

NBI maintains a website at www.nationalbankshares.com. The Company’s annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and all amendments to those reports are made available on its website as soon as is practical after the material is electronically filed with the Securities and Exchange Commission. The Company’s proxy materials for the 2016 annual meeting of stockholders are also posted on a separate website at www.nationalbanksharesproxy.com.

Item 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 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 State 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.

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 recovery 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 affected by a change in interest rates and related factors, including the pricing of securities.

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.

Focus on lending to small to mid-sized community-based businesses may increase its credit risk.

      Most of 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. 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.

9

Market interest rates remain low. When market interest rates rise farther, 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, because our interest-bearing liabilities (generally deposits) reprice sooner than our interest-earning assets (generally loans).

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

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

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. Until economic and market conditions improve, 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.

An increase in bank failures nationwide could significantly increase the cost of FDIC insurance.

Since insured depositary institutions, including our bank bear the full cost of deposit insurance provided by FDIC, a high number of bank failures could put additional pressure on a stressed Deposit Insurance Fund. This possibility could in turn lead to higher assessments that could negatively impact our earnings.

10

If more competitors come into our market area, 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 and stockbrokers 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 could lead to a significant increase in our regulatory burden.

The Dodd-Frank Act and its implementing regulations has resulted in greater compliance costs and reduced the profitability of some of our products and services. Implementation of the proposed Basel III rules for capital could increase our compliance costs because of the complexity in the risk assessment rules. Both federal and state governments could enact new laws affecting financial institutions that would further increase our regulatory burden and could negatively affect our profits.

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

New laws and regulations could limit our ability to offer certain profitable products and services or require that we offer unprofitable 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.

The regulatory environment has caused financial industry regulators to impose additional requirements, such as higher capital limits, which could impact the Company’s earnings.

Political stalemates in the U.S. and world governments could negatively affect the financial markets.

Political stalemates in the U.S. and world governments 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 in 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 do occur, that they 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 operations and the Company’s business strategy. The Company has invested in accepted technologies, and annually reviews processes and practices that are designed to protect its networks, computers and data from damage or unauthorized access. Despite these security measures, the Company’s computer systems and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. A breach of any kind could compromise systems and the information stored there could be accessed, damaged or disclosed. 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.

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. 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.

11

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

Federal and state support for public colleges and universities in the Company’s market area has been adversely affected by the recession and budgetary considerations. As a result, our business may be adversely affected from declines in university programs, capital projects, employment 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 that 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, new guidance on the calculation of credit reserves using expected losses (Current Expected Credit Losses) versus incurred losses is close to being finalized and, upon implementation, 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 NASDAQ 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 NASDAQ Capital Market has been relatively low when compared with larger companies listed on the NASDAQ 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 the 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.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

$ in thousands, except per share data

The purpose of this discussion and analysis is to provide information about the results of operations, financial condition, liquidity and capital resources of National Bankshares, Inc. and its subsidiaries (the “Company”). The discussion should be read in conjunction with the material presented in Item 8, “Financial Statements and Supplementary Data,” of this Form 10-K.

Subsequent events have been considered through the date on which the Form 10-K was issued.

Cautionary Statement Regarding Forward-Looking Statements

We make forward-looking statements in this Form 10-K that are subject to significant risks and uncertainties.  These forward-looking statements include statements regarding our profitability, liquidity, allowance for loan losses, interest rate sensitivity, market risk, growth strategy, and financial and other goals, and are based upon our management’s views and assumptions as of the date of this report.  The words “believes,” “expects,” “may,” “will,” “should,” “projects,” “contemplates,” “anticipates,” “forecasts,” “intends,” or other similar words or terms are intended to identify forward-looking statements.

These forward-looking statements are based upon or are affected by factors that could cause our actual results to differ materially from historical results or from any results expressed or implied by such forward-looking statements. These factors include, but are not limited to, changes in:

● interest rates,

● general economic conditions,

● the legislative/regulatory climate,

● monetary and fiscal policies of the U.S. Government, including policies of the U.S. Treasury, the Office of the Comptroller of the Currency, the Federal Reserve Board and the Federal Deposit Insurance Corporation, and the impact of any policies or programs implemented pursuant to the Emergency Economic Stabilization Act of 2008 (“EESA”) the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) and other financial reform legislation,

● unanticipated increases in the level of unemployment in the Company’s trade area,

● the quality or composition of the loan and/or investment portfolios,

● demand for loan products,

● deposit flows,

● competition,

● demand for financial services in the Company’s trade area,

● the real estate market in the Company’s trade area,

● the Company’s technology initiatives, and

● applicable accounting principles, policies and guidelines.

These risks and uncertainties should be considered in evaluating the forward-looking statements contained in this report. We caution readers not to place undue reliance on those statements, which speak only as of the date of this report. This discussion and analysis should be read in conjunction with the description of our “Risk Factors” in Item 1A. of this Form 10-K.

The national economy and the Company’s market area have experienced a slow recovery since the economic recession of 2008 and 2009. Unemployment rates have slowly improved since the peak of the recession. If the economic recovery wavers or reverses, 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 State as a result of the recession 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. A reversal in the economic recovery could have an adverse effect on all financial institutions, including the Company.

Critical Accounting Policies

General

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

16

Allowance for Loan Losses

The allowance for loan losses is an accrual of estimated losses that have been sustained 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 able to be estimated, 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. Impaired loans that are not TDRs with an estimated impairment loss are placed on nonaccrual status. TDRs that have not met the re-payment requirement of 6 months of consecutive timely payments are designated nonaccrual.

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 with outstanding principal balances of $250 or more are based on a current appraisal. Appraisals are also used to value impaired loans with principal balances of $100 or greater and secured by one piece of collateral. Collateral-method impaired loans with principal balances below $100, or if secured by multiple pieces of collateral, below $250, are valued using an internal evaluation.

Appraisals and internal evaluations 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 incorporate market analysis, comparable sales analysis, cash flow analysis and market data pertinent to the property to determine market value. Appraisals are ordered and reviewed by employees independent of the lending transaction.

Internal evaluations are prepared 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 actual physical condition and characteristics, and the economic market conditions that affect the property’s market value. Evaluations incorporate multiple sources of data to arrive at a property’s market value, including physical inspection, tax values, 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 twelve 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. For loans that are not collateral dependent, the impairment loss is 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 or part of a larger impaired relationship are collectively evaluated.

Troubled debt restructurings are impaired loans and are measured for impairment under the same valuation methods as other impaired loans. Troubled debt restructurings are maintained in nonaccrual status until the loan has demonstrated reasonable assurance of repayment.

Collectively-evaluated loans

Non-impaired loans and smaller homogeneous impaired loans that are not troubled debt restructurings and not part of a larger impaired relationship are grouped by portfolio segments that are made up of 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 quantitative and qualitative factors. Loss rates are calculated for and applied to individual classes.

Beginning with the first quarter of 2014, the Company began calculating the applicable loss rates by averaging loss rates over the most recent 8 quarters. Prior to 2014, the Company averaged the current annual loss rate with the annual loss rate of the previous year. The two methods yield similar results for quarterly calculations and yield the same average loss rate for annual calculations. The Company transitioned to using 8 quarters in order to provide ease of calculation on an ongoing basis. The look-back period of 8 quarters beginning in 2014 and two years for periods ended December 31, 2013 and prior are applied consistently among all classes.

17

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

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 also evaluated, with standard allocations applied consistently to relevant classes.

The Company accrues additional estimated loss for criticized loans within each class and for loans designated high risk. High risk loans are defined as junior lien mortgages, loans with high loan-to-value ratios and loans with terms that require only interest 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, 2015 considered market and portfolio conditions during 2015 as well as the levels of delinquencies and net charge-offs in the eight quarters ended December 31, 2015. Given the continued economic challenges in the Company’s market area, the ultimate amount of loss could vary from that estimate. For additional discussion of the allowance, see the notes to the financial statements, “Asset Quality,” and “Provision and Allowance for Loan Losses.”

Goodwill and Core Deposit Intangibles

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. 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 NBI; while the third technique uses current market pricing multiples for change-of-control transactions involving companies comparable to NBI. 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.

Acquired intangible assets (such as core deposit intangibles) are recognized separately from goodwill if the benefit of the asset can be sold, transferred, licensed, rented, or exchanged, and amortized over its useful life. The Company amortizes intangible assets arising from branch purchase transactions over their useful life. Core deposit intangibles are subject to a recoverability test based on undiscounted cash flows, and to the impairment recognition and measurement provisions required for other long-lived assets held and used. The impairment testing showed that the expected cash flows of the intangible assets exceeded the carrying value.

Performance Summary

The following table presents NBI’s key performance ratios for the years ending December 31, 2015 and December 31, 2014:

	12/31/15			12/31/14
Return on average assets		1.37	%		1.51	%
Return on average equity		9.22	%		10.72	%
Basic net earnings per common share	$	2.28		$	2.43
Fully diluted net earnings per common share	$	2.28		$	2.43
Net interest margin (1)		3.86	%		4.00	%
Noninterest margin (2)		1.40	%		1.37	%

(1) Net Interest Margin – Year-to-date tax equivalent net interest income divided by year-to-date average earning assets.

(2) Noninterest Margin – Noninterest expense (excluding the provision for bad debts and income taxes) less noninterest income (excluding securities gains and losses) divided by average year-to-date assets.

The return on average assets for the year ended December 31, 2015 was 1.37%, a decrease from 1.51% for the year ended December 31, 2014. The return on average equity decreased from 10.72% for the year ended December 31, 2014 to 9.22% for the year ended December 31, 2015.

Reflecting both the effects of the low interest rate environment throughout 2015 on NBI’s yields and funding costs and the Company’s asset/liability management practices, the net interest margin decreased from 4.00% at year-end 2014 to 3.86% at December 31, 2015.

The noninterest margin increased from 1.37% to 1.40% over the same period, while      basic net earnings per common share decreased from $2.43 for the year ended December 31, 2014 to $2.28 for the year ended December 31, 2015.

Growth

NBI’s key growth indicators are shown in the following table:

	12/31/15		12/31/14
Securities	$	389,288	$	385,385
Loans, net		610,711		597,203
Deposits		1,018,859		982,428
Total assets		1,199,739		1,154,731

Total assets experienced growth in 2015, funded by increases in customer deposits. Customer deposits grew $36,431 or 3.71% from December 31, 2014, with increases mainly from municipal deposits and individuals seeking to safeguard principal by avoiding more volatile investments in financial markets. The liquidity provided by customer deposits supported growth in loans of $13,508 or 2.26%. Securities increased by $3,903 or 1.01%.

In both 2015 and 2014, the Company’s growth was internally generated and was not the result of acquisitions or other borrowings.

19

Asset Quality

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

	12/31/15			12/31/14
Nonperforming loans(1)	$	6,682		$	9,287
Loans past due 90 days or more and accruing		156			207
Other real estate owned		4,165			4,744
Allowance for loan losses to loans(2)		1.34	%		1.36	%
Net charge-off ratio		0.32	%		0.27	%

(1) Nonperforming loans include nonaccrual loans plus restructured loans in nonaccrual status. Accruing restructured loans are not included.

(2) Loans are net of unearned income and deferred fees.

The Company monitors asset quality indicators in managing credit risk and in determining the allowance and provision for loan losses. At December 31, 2015, nonperforming loans were $6,682 or 1.08% of loans net of unearned income and deferred fees. This compares to $9,287 and 1.53% at December 31, 2014. Loans past due 90 days or more and still accruing at year-end 2015 totaled $156, a decrease of $51 or 24.64%, from $207 at December 31, 2014. The net charge-off ratio increased from 0.27% for the year ended December 31, 2014 to 0.32% for the year ended December 31, 2015, while other real estate owned decreased $579 for the same period.

The Company’s risk analysis determined an allowance for loan losses of $8,297 at December 31, 2015, resulting in a provision for the year of $2,009. This compares with an allowance for loan losses of $8,263 as of December 31, 2014, and a provision of $1,641 for the year ended December 31, 2014. The ratio of the allowance for loan losses to loans decreased to 1.34%, from 1.36% at December 31, 2014. 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 “Balance Sheet – Loans – Risk Elements,” “Balance Sheet – Loans – Troubled Debt Restructurings,” as well as Notes 1 and 5 to the 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.” 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 for the year ended December 31, 2015 was $38,731, a decrease of $314, or 0.80%, when compared to the prior year. The net interest margin for 2015 was 3.86%, compared to 4.00% for 2014. Total interest income for the period ended December 31, 2015 was $42,914, a decrease of $1,030 from the period ended December 31, 2014. Interest expense declined by $716 during the same time frame, from $4,899 for the year ended December 31, 2014 to $4,183 for the year ended December 31, 2015. The decline in interest expense came about in part because higher priced certificates of deposit renewed at lower interest rates. In addition, low-rate interest-bearing deposits volume increased substantially. 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 earned is affected by various factors, including changes in market interest rates due to the Federal Reserve Board’s monetary policy, the level and composition of the earning assets, and the composition of interest-bearing liabilities. The Company has the ability to respond over time to interest rate movements and reduce volatility in the net interest margin. However, the frequency and/or magnitude of changes in market interest rates are difficult to predict and may have a greater impact on net interest income than adjustments by management.

During 2015, interest rates continued at historic lows. Offsetting the positive effect of low interest rates on customer deposits is the fact that some higher yielding securities in the Company’s investment portfolio were called and were replaced with securities with yields at the lower market rate. Another negative effect of the low interest rate environment is the level of interest earned on overnight funds. This impacted the yield on the Company’s interest-bearing deposits in other banks. The yield on the Company’s interest-bearing deposits in other banks assets in 2015 was 0.26%, while the cost of interest-bearing liabilities was 0.51% in the same period. These assets are used primarily to provide liquidity.

The primary source of funds used to support the Company’s interest-earning assets is deposits. Deposits are obtained in the Company’s trade area through traditional marketing techniques. Other funding sources, such as the Federal Home Loan Bank, while available, are only used occasionally. The cost of funds is dependent on interest rate levels and competitive factors. This limits the ability of the Company to react to interest rate movements.

20

The factors that may influence the Company’s net interest margin include current Federal Reserve policies that depress long-term interest rates, and market forces that may encourage repricing of interest-bearing liabilities more quickly than interest-earning assets if rates were to increase.      On December 16, 2015, the Federal Reserve raised its target federal funds rate from a range of 0% to 0.25%, to a range of 0.25% to 0.5%. This was the first rate increase in almost a decade. The Company expects the rate increase will have a small but positive impact on the Company’s future net interest income. Because interest rates continue at low levels, the Company expects that interest rates will likely increase in the future. Management cannot predict the timing and level of interest rate increases.

Analysis of Changes in Interest Income and Interest Expense

The Company’s primary source of revenue is net interest income, which is the difference between the interest and fees earned on loans and investments and the interest paid on deposits and other funds. The Company’s net interest income is affected by changes in the amount and mix of interest-earning assets and interest-bearing liabilities and by changes in yields earned on interest-earning assets and rates paid on interest-bearing liabilities. The following table sets forth, for the years indicated, a summary of the changes in interest income and interest expense resulting from changes in average asset and liability balances (volume) and changes in average interest rates (rate).

	2015 Over 2014									2014 Over 2013
	Changes Due To									Changes Due To

(1)	Taxable equivalent basis using a Federal income tax rate of 35% in 2015, 2014 and 2013.
(2)	Variances caused by the change in rate times the change in volume have been allocated to rate and volume changes proportional to the relationship of the absolute dollar amounts of the change in each.

Total interest expense declined by $716, while interest income on a taxable-equivalent basis decreased $1,093, resulting in a decrease of $377 in taxable-equivalent net interest income when 2015 and 2014 are compared. Declining rates impacted net interest income by $1,786, offset by increases due to favorable changes in volume of $1,409.

Lower interest rates led to a decline of $1,882 in interest income from loans. The average balance of loans increased from $593,327 in 2014 to $620,547 in 2015, causing an increase in interest income of $1,412.

Interest income on taxable securities decreased $581 due to rates, offset by an increase of $559 due to average volume, for a net decrease of $22 compared to 2014. Interest on non-taxable securities on a fully-taxable equivalent basis declined $50 due to rates and $543 due to volume. The continued low interest rate environment resulted in a large number of called securities during 2015 and reduced the opportunity to reinvest the proceeds in securities with more attractive yields. Because of low yields in the securities markets and a highly competitive loan environment, the Company priced deposits accordingly.

Interest on time deposits declined $246 from 2014 to 2015, with a decline of $84 due to rates and $162 due to decreased volume. See “Net Interest Income” for additional information related to the decline in interest expense.

The low interest rate environment was also present in 2014 and 2013. As compared with 2013, there was a $692 decline in interest expense associated with time deposits in 2014. Of the total decline, $465 was due to rates, and $227 stemmed from lower deposit volume. Management focused on deposit pricing and took advantage of falling rates to lower interest expense.

From 2013 to 2014 interest on loans decreased by $1,376. Reduced rates contributed $1,728 to the decline, partially offset by an increase of $352 due to increased volume. As compared with 2013, there was a decrease of $931 in net interest income in 2014, with an increase due to volume of $62, offset by declines due to rate of $993.

Interest Rate Sensitivity

The Company considers interest rate risk to be a significant market risk and has systems in place to measure the exposure of net interest income and fair market values to movement in interest rates. Among the tools available to management is interest rate sensitivity analysis, which provides information related to repricing opportunities. Interest rate shock simulations indicate potential economic loss due to future interest rate changes. Shock analysis is a test that measures the effect of a hypothetical, immediate and parallel shift in interest rates. The following table shows the results of a rate shock and the effects on the return on average assets and the return on average equity projected at December 31, 2015 and 2014. For purposes of this analysis, noninterest income and expenses are assumed to be flat.

Rate Shift (bp)	Return on Average Assets						Return on Average Equity
	2015			2014			2015			2014
300		1.57	%		1.58	%		10.54	%		7.58	%
200		1.54	%		1.44	%		10.37	%		6.99	%
100		1.51	%		1.39	%		10.20	%		6.45	%
(-)100		1.36	%		1.27	%		9.18	%		5.53	%
(-)200		1.32	%		1.18	%		8.91	%		5.73	%
(-)300		1.34	%		1.09	%		9.05	%		5.78	%

Simulation analysis is another tool available to the Company to test asset and liability management strategies under rising and falling rate conditions. As a part of the simulation process, certain estimates and assumptions must be made. These include, but are not limited to, asset growth, the mix of assets and liabilities, rate environment and local and national economic conditions. Asset growth and the mix of assets can, to a degree, be influenced by management. Other areas, such as the rate environment and economic factors, cannot be controlled. In addition, competitive pressures can make it difficult to price deposits and loans in a manner that optimally minimizes interest rate risk. Therefore, actual results may vary materially from any particular forecast or shock analysis. This shortcoming is offset somewhat by the periodic reforecasting of the balance sheet to reflect current trends and economic conditions. Shock analysis must also be updated periodically as a part of the asset and liability management process.

Noninterest Income

Realized securities gains		33		2		(46	)
Total noninterest income	$	9,486	$	9,120	$	9,222

Service charges on deposit accounts totaled $2,250 for the year ended December 31, 2015. This is a decline of $184, or 7.56%, from $2,434 for the year ended December 31, 2014. Service charges on deposit accounts decreased $129, or 5.03%, from 2013 to 2014. This income category is affected by the number of deposit accounts, the level of service charges and the number of checking account overdrafts. The 2015 decline resulted primarily from a decrease of $186 in non-sufficient funds and overdraft fees. The 2014 decline resulted primarily from a decrease of $89 in ATM transaction fees and a decrease of $48 in account service charges.

Other service charges and fees included charges for official checks, income from the sale of checks to customers, safe deposit box rent, fees from letters of credit and income from commissions on the sale of credit life, accident and health insurance. These fees were $215 for the year ended December 31, 2015, an increase of $28, or 14.97%, from the $187 for 2014. The total for the year ended December 31, 2014 was $38 below the $225 posted for the year ended December 31, 2013. The changes are primarily due to low check sales in 2014. Fees associated with check sales declined from 2013 to 2014 and improved in 2015.

Credit card fees for the year ended December 31, 2015, were $230 above the $3,631 reported for the year ended December 31, 2014. From 2013 to 2014, credit card fees increased $301, or 9.04%. The increases in 2015 and 2014 are due to increased volume of merchant transaction fees and credit card fees.

Trust fees at $1,229 increased by $16 or 1.32% when the years ended December 31, 2015 and 2014 are compared. For the year ended December 31, 2014 trust fees were $1,213, an increase of $63, or 5.48%, from 2013. Trust fees are generated from a number of different types of accounts, including estates, personal trusts, employee benefit trusts, investment management accounts, attorney-in-fact accounts and guardianships. Trust income varies depending on the number and type of accounts under management and financial market conditions. The mix of account types also affected the level of trust fees in 2014 and 2015.

Noninterest income from bank-owned life insurance (BOLI) decreased, from $616 for the year ended December 31, 2014 to $603 for 2015. BOLI income for the year ended December 31, 2013 was $658. Income from bank-owned life insurance was affected by the performance of the variable rate policies.

23

Other income is income from smaller balance accounts that cannot be classified in another category. Some examples include gains on mortgage loans sold, net gains from the sales of fixed assets and revenue from investment and insurance sales. Other income for 2015 was $1,295, an increase of $258, or 24.88%, when compared with $1,037 for the year ended December 31, 2014. The increase from 2014 to 2015 stemmed primarily from an increase in gains on mortgage loans sold of $114 and a vendor signing incentive of $100. Other income for 2014 decreased $305 or 22.73% when compared with $1,342 for the year ended December 31, 2013. The decrease from 2013 to 2014 stemmed primarily from a decrease in gains of mortgage loans sold of $176 and a decrease in income from other investments of $77.

Realized securities net gains for the three years presented were primarily associated with called securities. The Company did not sell any securities in 2015 or 2014. The Company sold five securities in the available for sale accounting designation in 2013.

Salary and benefits expense increased $916, or 7.89%, from $11,606 for the year ended December 31, 2014 to $12,522 for 2015. Employee salaries increased $230 or 2.62%, which were the result of normal staffing and compensation decisions. The remaining portion of the increase stemmed primarily from fringe benefits and other compensation expense. Fringe benefits expense increased $168. Other compensation expenses, including pension expense, employee stock ownership expense and salary continuation expense increased $449. Salary and benefits expense decreased $301, or 2.53%, from $11,907 for the year ended December 31, 2013 to $11,606 for 2014. An increase in fringe benefits expense of $390 partially offset a decline in other salary expenses, which were the result of normal staffing and compensation decisions.

Occupancy, furniture and fixtures expense was $1,728 for the year ended December 31, 2015, an increase of $25, or 1.47%, from the prior year. The 2014 total was $1,703, an increase of $87, or 5.38%, from the $1,616 reported at year-end 2013. The small increases in 2015 and 2014 are reflective of the Company’s emphasis on containing controllable expenses.

Data processing and ATM expense was $1,657 in 2015, $1,650 in 2014 and $1,700 in 2013. Data processing and ATM expense in 2014 benefitted from infrastructure upgrades performed in 2013.

When the years ended December 31, 2015 and December 31, 2014 are compared, the Federal Deposit Insurance Corporation Deposit Insurance Fund expense increased $13 or 2.44%. The total expense for 2015 was $546, which compares with $533 for 2014. The FDIC assessment expense for the year ended December 31, 2014 decreased $21 from $554 for 2013. The FDIC assessment is accrued based on a method provided by the FDIC.

Credit card processing expense was $2,692 for the period ended December 31, 2015, an increase of $99, or 3.82% from 2014’s total of $2,593. Credit card processing expense in 2014 increased $47, or 1.85% from 2013. This expense is driven by the volume of credit card, debit card and merchant account transactions and by the level of merchant discount fees. It is subject to a degree of variability.

The expense for intangibles and goodwill amortization is related to acquisitions. There were no acquisitions in the last year, and the expense for 2015 decreased from 2014 by $76 or 7.07%. The expense for intangibles and goodwill amortization decreased $3 from 2013 to 2014.

Net costs of other real estate owned increased from $369 for the period ended December 31, 2014 to $608 for the year ended December 31, 2015. From 2013 to 2014, net costs of other real estate owned increased $73 from $296. This expense category varies with the number of foreclosed properties owned by NBB and with the expense associated with each. It includes write-downs on other real estate owned plus other costs associated with carrying these properties, as well as net gains or losses on the sale of other real estate. In 2015, write-downs on other real estate were $440. This compares with $84 in 2014 and $80 in 2013. Other real estate is initially accounted for at fair value less estimated costs to sell using current valuations, which include appraisals, real estate evaluations and realtor market opinions. If new valuation information indicates a decline from the initial basis, the Company records a write-down. Other costs for these properties in 2015 were $181, compared with $240 in 2014. The Company recorded a gain of $14 on the sale of OREO in 2015 and net losses of $45 for 2014. Because the Company’s market area continues to experience the effects of the prolonged recession and slow recovery, it is anticipated that there will be additional foreclosures in the near future. The Company currently has loans totaling $228 in process of foreclosure. While some of the loans may be resolved in a manner other than foreclosure, it is likely that some loans will be foreclosed and may result in an associated increase in the costs of other real estate owned.

24

Franchise taxes were $1,288 for the period ended December 31, 2015 and $1,182 for 2014, an increase of $106 or 8.97%. Franchise tax expense increased $99 in 2014 from $1,083 in 2013. State bank franchise taxes are based upon total equity, which increased in both 2014 and 2015.

The category of other operating expenses includes noninterest expense items such as professional services, stationery and supplies, telephone costs and charitable donations. For the year ended December 31, 2015, other operating expenses were $3,595. This compares with $3,721 for 2014 and $3,519 for 2013. The $126 decrease from 2014 to 2015 and the $202 increase from 2013 to 2014 are the results of changes in several categories of expense, with no one item making a significant contribution to the total.

Income Taxes

Income tax expense for 2015 was $4,740 compared to $5,178 in 2014 and $5,317 in 2013. Tax exempt income is the primary difference between expected and actual income tax expense. The Company’s effective tax rates for 2015, 2014 and 2013 were 23.04%, 23.44% and 23.01%, respectively. The Company is subject to the 35% marginal tax rate. See Note 10 of the Notes to Consolidated Financial Statements for addition information relating to income taxes.

Effects of Inflation

The Company’s consolidated statements of income generally reflect the effects of inflation. Since interest rates, loan demand and deposit levels are related to inflation, the resulting changes are included in net income. The most significant item which does not reflect the effects of inflation is depreciation expense. Historical dollar values used to determine depreciation expense do not reflect the effects of inflation on the market value of depreciable assets after their acquisition.

Provision and Allowance for Loan Losses

The Company’s risk analysis determined an allowance for loan losses of $8,297 or 1.34% of total loans at December 31, 2015, compared with $8,263 or 1.36% of total loans at December 31, 2014. The determination of the appropriate level for the allowance for loan losses resulted in a provision of $2,009 for the year ended December 31, 2015 and $1,641 for the year ended December 31, 2014. To determine the appropriate level of the allowance for loan losses, the Company considers credit risk for certain loans designated as impaired and for non-impaired (“collectively evaluated”) loans.

Individually evaluated impaired loans totaled $15,346 with specific allocations to the allowance for loan losses of $45 at December 31, 2015, compared with individually evaluated impaired loans of $15,121 with specific allocations of $282 at December 31, 2014. The specific allocation is determined based on criteria particular to each impaired loan.

For collectively evaluated loans, the Company applies to each loan class a historical net charge-off rate, averaged over the most recent eight quarters, and adjusted for factors that influence credit risk. Collectively evaluated loans totaled $604,538, with an allowance of $8,252 or 1.37% of the collectively-evaluated portfolio at December 31, 2015. At December 31, 2014, collectively evaluated loans totaled $591,198 with an allowance of $7,981 or 1.35% of the collectively-evaluated portfolio.

Net charge-offs for the year ended December 31, 2015 were $1,975 or 0.32% of total average loans, an increase when compared with $1,605 or 0.27% for the year ended December 31, 2014. Net charge-offs for the year ended December 31, 2013 were $1,653 or 0.28% of average loans. The increase in the aggregate net charge-off rate increased the Company’s determination of the appropriate level for the allowance for loan losses for collectively-evaluated loans at December 31, 2015.

Asset quality indicators affect the level of the allowance for loan losses. Accruing loans past due 30-89 days increased to 0.48% of total loans at December 31, 2015, from 0.40% of total loans at December 31, 2014, increasing the required level of the allowance for loan losses at December 31, 2015. This increase was offset by improvement in the level of nonaccrual loans. Nonaccrual loans decreased to 1.08% of total loans at December 31, 2015, from 1.53% at December 31, 2014. On an aggregate basis, accruing loans past due 90 days or more were 0.03% of total loans for both December 31, 2015 and 2014.

Loans rated “special mention” and “classified” indicate heightened credit risk. Collectively evaluated loans rated “special mention” increased to $6,144 at December 31, 2015, from $5,300 at December 31, 2014. The increase resulted in an increased requirement for the allowance for loan losses. This was offset by a decrease in the level of collectively evaluated loans rated classified. Collectively evaluated loans rated classified were $6,071 at December 31, 2015, compared with $10,285 at December 31, 2014.

Other portfolio attributes, including high risk loans, are considered to determine the appropriate level of the allowance for loan loss. High risk loans, defined by the Company as loans secured by junior liens, interest-only loans and loans with a high loan-to-value ratio, increased from December 31, 2014 to December 31, 2015, resulting in an increase requirement for the allowance for loan losses.

Economic factors contribute to the calculation of the allowance for loan loss. The impact to the allowance for most economic factors applied to the December 31, 2015 calculation remained at similar levels or increased slightly when compared with levels at December 31, 2014. However the level of business bankruptcy filings increased substantially and contributed to an increased requirement for the allowance for loan losses. This was partially offset by lower residential vacancy rates in the Company’s market area, which reduced the required level of the allowance for loan losses.

25

The calculation of the appropriate level for the allowance for loan losses incorporates analysis of multiple factors and requires management’s prudent and informed judgment. The ratio of the allowance for loan losses for the total loan portfolio declined from December 31, 2014, however the ratio of the collectively-evaluated allowance for loan losses increased. The increase was driven by increases in net charge-offs, accruing loans 30-89 days past due, levels of loans rated “special mention”, levels of high-risk loans and certain economic factors, partially offset by positive changes in levels of nonaccrual loans, classified loans and certain other economic factors. Based on the analysis, management believes the level of allowance for loan losses is reasonable for the credit risk in the loan portfolio.

Accruing loans past due 90 days or more	$	156		$	207		$	190

Nonperforming loans include nonaccrual loans and restructured loans (“troubled debt restructurings” or “TDR loans”) in nonaccrual status, but do not include accruing loans 90 days or more past due or accruing restructured loans. Troubled debt restructurings are discussed in detail under the section titled “D. Modifications and Troubled Debt Restructurings (TDR Loans)” below. Impaired loans, or loans for which management does not expect to collect at the original loan terms, but which may or may not be nonperforming, are presented in Note 5 of Notes to Consolidated Financial Statements.

Total impaired loans at December 31, 2015 were $15,346, of which $6,532 were in nonaccrual status. Impaired loans at December 31, 2014 and 2013 were $15,121 and $12,985, of which $8,794 and $6,190 were in nonaccrual status, respectively.

The ratio of the allowance for loan losses to total nonperforming loans increased from 88.97% in 2014 to 124.17% in 2015. The Company believes the allowance for loan losses is adequate for the credit risk inherent in the loan portfolio.

D.     Modifications and Troubled Debt Restructurings (“TDRs”)

In the ordinary course of business the Company modifies loan terms on a case-by-case basis, including both consumer and commercial loans, for a variety of reasons. Modifications to consumer loans generally involve short-term deferrals to accommodate specific, temporary circumstances. The Company may grant extensions to borrowers who have demonstrated a willingness and ability to repay their loan but who are experiencing consequences of a specific unforeseen temporary hardship.

An extension defers monthly payments and requires a balloon payment at the original contractual maturity. Where the temporary event is not expected to impact a borrower’s ability to repay the debt, and where the Company expects to collect all amounts due including interest accrued at the contractual interest rate for the period of delay at contractual maturity, the modification is not designated a TDR.

Modifications to commercial loans may include, but are not limited to, changes in interest rate, maturity, amortization and financial covenants. In the original underwriting, loan terms are established that represent the then-current and projected financial condition of the borrower. If the modified terms are consistent with competitive market conditions and representative of terms the borrower could otherwise obtain in the open market, the modified loan is not categorized as a TDR.

The Company codes modifications to assist in identifying troubled debt restructurings. The majority of modifications were granted for competitive reasons and did not constitute troubled debt restructurings. A description of modifications that did not result in troubled debt restructurings follows:

(1) The Company began coding modifications during the second quarter of 2013.

Modifications in which the borrower is experiencing financial difficulty and for which the Company makes a concession to the original contractual loan terms are designated troubled debt restructurings.

Modifications of loan terms to borrowers experiencing financial difficulty are made in an attempt to protect as much of the Company’s investment in the loan as possible. The determination of whether a modification should be accounted for as a TDR requires significant judgment after consideration of all facts and circumstances surrounding the transaction.

Assuming all other TDR criteria are met, the Company considers one or a combination of the following concessions to the loan terms to indicate TDR status: a reduction of the stated interest rate, an extension of the maturity date at an interest rate lower than the current market rate for a new loan with a similar term and similar risk, or forgiveness of principal or accrued interest.

The Company recognizes that in the current economy elevated levels of unemployment and depressed real estate values have resulted in financial difficulties for some customers. The Company has restructured loan terms for certain qualified financially distressed borrowers who have agreed to work in good faith and have demonstrated the ability to make the restructured payments in order to avoid a foreclosure. All TDR loans are individually evaluated for impairment for purposes of determining the allowance for loan losses. TDR loans with an impairment loss or that do not demonstrate current payments for at least six months are maintained on nonaccrual until the borrower demonstrates sustained repayment history under the restructured terms and continued repayment is not in doubt. Otherwise, interest income is recognized using a cost recovery method.

The Company had $13,453 in TDRs as of December 31, 2015 and $11,328 as of December 31, 2014. Accruing TDR loans amounted to $8,814 at December 31, 2015 compared to $6,040 at December 31, 2014.

Restructuring generally results in loans with either lower payments or an extended maturity beyond that originally required, and are expected to have a lower risk of loss due to nonperformance than loans classified as nonperforming. In 2015, the Company modified loans in troubled debt restructurings that, directly prior to restructuring, totaled $3,628 and that have total principal balances of $3,504 as of December 31, 2015. Some of the Company’s restructured loans defaulted during the twelve months ended December 31, 2015. The Company defines default as a delay in one payment of more than 90 days or charge-offs or foreclosure after the date of restructuring. All of the restructured loans that defaulted had been modified more than twelve months prior to default.

In 2014, the Company modified loans in troubled debt restructurings that, directly prior to restructuring, totaled $5,671 and that had total principal balances of $5,203 as of December 31, 2014. All of the restructured loans that defaulted in 2014 had been modified more than twelve months prior to default.

Please refer to Note 5 for information on the effect of default on the allowance for loan losses.

Summary of Loan Loss Experience

A.     Analysis of the Allowance for Loan Losses

The following tabulation shows average loan balances at the end of each period; changes in the allowance for loan losses arising from loans charged off and recoveries on loans previously charged off by loan category; and additions to the allowance which have been charged to operating expense:

	December 31,
	2015			2014			2013			2012			2011
Average loans, net of unearned income	$	619,745		$	592,944		$	585,991		$	588,170		$	588,439

Provision charged to operations		2,009			1,641			1,531			3,134			2,949
Allowance for loan losses at end of year	$	8,297		$	8,263		$	8,227		$	8,349		$	8,068
Net charge-offs to average net loans outstanding		0.32	%		0.27	%		0.28	%		0.49	%		0.43	%

The Company charges off commercial real estate loans at the time that a loss is confirmed. When delinquency status or other information indicates that the borrower will not repay the loan, the Company considers collateral value based upon a current appraisal or internal evaluation. Any loan amount in excess of collateral value is charged off and the collateral is taken into other real estate owned.

Factors influencing management’s judgment in determining the amount of the loan loss provision charged to operating expense include: the quality of the loan portfolio as determined by management, the historical loan loss experience, diversification as to type of loans in the portfolio, the amount of secured as compared with unsecured loans and the value of underlying collateral, banking industry standards and averages, and economic conditions. Management evaluates the quality of the loan portfolio by examining past due and nonaccrual ratios for each class. The ratio of loans past due 30-89 days to total loans increased from 0.40% at December 31, 2014 to 0.48% at December 31, 2015, while the ratio of accruing loans 90 days past due to total loans remained essentially static at 0.03%, and nonaccrual loans as a percentage of total loans decreased from 1.53% at December 31, 2014 to 1.08% at December 31, 2015.

Historical losses are computed and incorporated into the calculation for the allowance for loan losses on the class level. On a total portfolio basis, the net charge-off rate for the twelve months ended December 31, 2015 increased 5 basis points to 0.32% from 0.27% for the twelve months ended December 31, 2014. Class balances as a percentage of total loans are evaluated to determine growth areas. Classes that increased were construction loans other; one-to-four family residential real estate, closed-end junior liens; commercial and industrial loans; public sector and IDA; automobile loans; and other consumer loans. High risk loans, defined by the Company to be junior lien mortgages, interest only loans and loans with high loan-to-value ratios, were examined. The percentage of high-risk loans as a percentage of total loans increased slightly from December 31, 2014.

33

Economic factors were analyzed to determine their impact on the credit risk of the loan portfolio. From December 31, 2014 to December 31, 2015, positive indicators were decreases in unemployment, home vacancy rates and the inventory of existing homes on the market, while average bankruptcy rates were found to have increased. Management’s analysis of the loan portfolio and pertinent economic conditions resulted in a determination of the allowance for loan losses for collectively-evaluated loans of $8,252 at December 31, 2015, up from $7,981 at December 31, 2014. As of December 31, 2015, the unallocated portion of the reserve was $28, and at December 31, 2014 the unallocated reserve was $48. Individually-evaluated impaired loans are valued using the appraised value of the underlying collateral or the present value of cash flows for each loan. Valuation procedures for impaired loans resulted in a required reserve for impaired loans of $45 at December 31, 2015 and $282 at December 31, 2014. The total required reserves of $8,297 at December 31, 2015, $8,263 as of December 31, 2014 and $8,227 as of December 31, 2013 indicated provision charges for loan losses of $2,009 for the twelve months ended December 31, 2015, $1,641 for the twelve months ended December 31, 2014 and $1,531 for the twelve months ended December 31, 2013.

B.     Allocation of the Allowance for Loan Losses

The allowance for loan losses has been allocated according to the amount deemed necessary to provide for anticipated losses within the categories of loans for the years indicated as follows:

	December 31,
	2015					2014					2013					2012					2011
	Allowance Amount		Percent of Loans in Each Category to Total Loans			Allowance Amount		Percent of Loans in Each Category to Total Loans			Allowance Amount		Percent of Loans in Each Category to Total Loans			Allowance Amount		Percent of Loans in Each Category to Total Loans			Allowance Amount		Percent of Loans in Each Category to Total Loans
Real estate construction	$	576		7.78	%	$	612		7.52	%	$	863		7.70	%	$	1,070		8.48	%	$	1,079		8.23	%
Consumer real estate		1,866		23.15	%		1,662		24.25	%		1,697		24.39	%		2,263		24.15	%		1,245		25.49	%

	$	8,297		100.00	%	$	8,263		100.00	%	$	8,227		100.00	%	$	8,349		100.00	%	$	8,068		100.00	%

34

An analysis of the allowance for loan losses by impairment basis follows:

	December 31,
	2015			2014			2013
Impaired loans	$	15,346		$	15,121		$	12,985
Allowance related to impaired loans		45			282			624
Allowance to impaired loans		0.29	%		1.87	%		4.81	%
Non-impaired loans		604,538			591,198			583,610
Allowance related to non-impaired loans		8,252			7,981			7,603
Allowance to non-impaired loans		1.37	%		1.35	%		1.30	%
Total loans		619,884			606,319			596,595
Less: unearned income and deferred fees		(876	)		(853	)		(905	)
Loans, net of unearned income and deferred fees		619,008			605,466			595,690
Allowance for loan losses, total		8,297			8,263			8,227
Allowance as a percentage of loans, net of unearned		1.34	%		1.36	%		1.38	%

The allowance percentage for impaired loans was 0.29%, 1.87% and 4.81% as of December 31, 2015, 2014 and 2013 respectively. The ratio is subject to fluctuation because impaired loans are individually evaluated. The amount of the individual impaired loan balance that exceeds the fair value is accrued in the allowance for loan losses.

The allowance percentage for non-impaired loans was 1.37%, 1.35% and 1.30% as of December 31, 2015, 2014 and 2013 respectively. The allowance for non-impaired loans is determined by applying historical charge-off percentages, as well as additional accruals for internal and external credit risk factors to groups of non-impaired loans. The ratio increased from 2014 due to increases in net charge-offs, accruing loans 30-89 days past due, levels of loans rated “special mention”, levels of high-risk loans and certain economic factors, partially offset by positive changes in levels of nonaccrual loans, classified loans and certain other economic factors. The ratio increased from 2013 to 2014 due to increases in nonaccrual loans and criticized loans, as well as the impact of certain economic factors.

Securities

The fair value of securities available for sale was $236,131, an increase of $13,287 or 5.96% from December 31, 2014. The amortized cost of securities held to maturity was $152,028 at December 31, 2015 and $161,452 at December 31, 2014, a decrease of $9,424 or 5.84%.

Additional information about securities available for sale and securities held to maturity can be found in Note 3 of the Notes to Consolidated Financial Statements.

The financial markets have experienced increased volatility and increased risk during the economic downturn and slow recovery. The risk in financial markets affects the Company in the same way that it affects other institutional and individual investors. The Company’s investment portfolio includes corporate bonds. If, because of economic hardship, the corporate issuers were to default, there could be a delay in the payment of interest, or there could be a loss of principal and accrued interest. To date, there have been no defaults in any of the corporate bonds held in the portfolio. The Company’s investment portfolio also contains a large percentage of municipal bonds. The recession and a slow recovery may negatively impact the ability of states and municipalities to make scheduled principal and interest payments on their outstanding indebtedness. If their income from taxes and other sources declines significantly, states and municipalities could default on their bond obligations. There have been no defaults among the municipal bonds in the Company’s investment portfolio.

In making investment decisions, management follows internal policy guidelines that help to limit risk by specifying parameters for both security quality and industry and geographic concentrations. Management regularly monitors the quality of the investment portfolio and tracks changes in financial markets. The value of individual securities will be written down if a decline in fair value is considered to be other than temporary, given the totality of the circumstances.

The majority of mortgage-backed securities and collateralized mortgage obligations held at December 31, 2015 were backed by U.S. agencies. Certain holdings are required to be periodically subjected to the Federal Financial Institution Examination Council’s (FFIEC) high risk mortgage security test. These tests address possible fluctuations in the average life and variances caused by the change in rate times the change in volume that have been allocated to rate and volume changes proportional to the relationship of the absolute dollar amounts of the change in each. Except for U.S. Government securities, the Company has no securities with any issuer that exceeds 10% of stockholders’ equity.

Deposits

Total deposits increased by $36,431 or 3.71%, from $982,428 at December 31, 2014 to $1,018,859 at December 31, 2015. Total deposits grew $22,392, or 2.33%, from $960,036 at December 31, 2013 to December 31, 2014. A portion of the increase in both 2015 and 2014 is attributable to a higher level of municipal deposits. The increases in total deposits for 2015 and 2014 were internally generated and not the result of acquisitions.

Derivatives and Market Risk Exposures

The Company is not a party to derivative financial instruments with off-balance sheet risks such as futures, forwards, swaps, and options. The Company is a party to financial instruments with off-balance sheet risks such as commitments to extend credit, standby letters of credit, and recourse obligations in the normal course of business to meet the financing needs of its customers. See Note 14, of Notes to Consolidated Financial Statements for additional information relating to financial instruments with off-balance sheet risk. Management does not plan any future involvement in high risk derivative products. The Company has investments in mortgage-backed securities, principally GNMA’s and FNMA’s, with a fair value of approximately $1,682. See Note 3 of Notes to Consolidated Financial Statements for additional information relating to securities.

The Company’s securities and loans are subject to credit and interest rate risk, and its deposits are subject to interest rate risk. Management considers credit risk when a loan is granted and monitors credit risk after the loan is granted. The Company maintains an allowance for loan losses to absorb losses in the collection of its loans. See Note 5 of Notes to Consolidated Financial Statements for information relating to the allowance for loan losses. See Note 15 of Notes to Consolidated Financial Statements for information relating to concentrations of credit risk. The Company has an asset/liability program to manage its interest rate risk. This program provides management with information related to the rate sensitivity of certain assets and liabilities and the effect of changing rates on profitability and capital accounts.

The effects of changing interest rates are primarily managed through adjustments to the loan portfolio and deposit base, to the extent competitive factors allow. The investment portfolio is generally longer term. Adjustments for asset and liability management are made when securities are called or mature and funds are subsequently reinvested. Securities may be sold for reasons related to credit quality or regulatory limitations, and in limited circumstances, securities available for sale have been disposed of for interest rate risk management. No trading activity for this purpose is planned in the foreseeable future, though it does remain an option.

While the asset/liability planning program is designed to protect the Company over the long term, it does not provide near-term protection from interest rate shocks, as interest rate sensitive assets and liabilities do not by their nature move up or down in tandem in response to changes in the overall rate environment. The Company’s profitability in the near term may be temporarily negatively affected in a period of rapidly rising or rapidly falling rates, because it takes some time for the Company to change its rates to adjust to a new interest rate environment. See Note 16 of Notes to Consolidated Financial Statements for information relating to fair value of financial instruments and comments concerning interest rate sensitivity.

Liquidity

Liquidity measures the Company’s ability to meet its financial commitments at a reasonable cost. Demands on the Company’s liquidity include funding additional loan demand and accepting withdrawals of existing deposits. The Company has diverse liquidity sources, including customer and purchased deposits, customer repayments of loan principal and interest, sales, calls and maturities of securities, Federal Reserve discount window borrowing, short-term borrowing, and Federal Home Loan Bank advances. At December 31, 2015, the bank did not have discount window borrowings, short-term borrowings, or FHLB advances.  To assure that short-term borrowing is readily available, the Company tests accessibility annually.

Liquidity from securities is restricted by accounting and business considerations. The securities portfolio is segregated into available-for-sale and held-to-maturity. The Company considers only securities designated available-for-sale for typical liquidity needs.  Further, portions of the securities portfolio are pledged to meet state requirements for public funds deposits. Discount window borrowings also require pledged securities. Increased/decreased liquidity from public funds deposits or discount window borrowings results in increased/decreased liquidity from pledging requirements. The Company monitors public funds pledging requirements and unpledged available-for-sale securities accessible for liquidity needs.

Regulatory capital levels determine the Company’s ability to use purchased deposits and the Federal Reserve discount window. At December 31, 2015, the Company is considered well capitalized and does not have any restrictions on purchased deposits or borrowing ability at the Federal Reserve discount window.

The Company monitors factors that may increase its liquidity needs. Some of these factors include deposit trends, large depositor activity, maturing deposit promotions, interest rate sensitivity, maturity and repricing timing gaps between assets and liabilities, the level of unfunded loan commitments and loan growth. At December 31, 2015, the Company’s liquidity is sufficient to meet projected trends in these areas.

To monitor and estimate liquidity levels, the Company performs stress testing under varying assumptions on credit sensitive liabilities and the sources and amounts of balance sheet and external liquidity available to replace outflows. The Company’s Contingency Funding Plan sets forth avenues for rectifying liquidity shortfalls. At December 31, 2015, the analysis indicated adequate liquidity under the tested scenarios.

The Company utilizes several other strategies to maintain sufficient liquidity. Loan and deposit growth are managed to keep the loan to deposit ratio within the Company’s own policy range of 65% to 75%. At December 31, 2015, the loan to deposit ratio was 60.76%, slightly below policy levels. The investment strategy takes into consideration the term of the investment, and securities in the available for sale portfolio are laddered based upon projected funding needs.

In the normal course of business, we enter into certain contractual obligations, including obligations to make future payments on lease arrangements, contractual commitments with depositors, and service contracts. The table below presents our significant contractual obligations as of December 31, 2015, except for pension and other postretirement benefit plans, which are included in Note 8, "Employee Benefit Plans," to the Consolidated Financial Statements in this Form 10-K.

(1) Includes contracts with a minimum annual payment of $100

As of December 31, 2015, the Company was not aware of any other known trends, events or uncertainties that have or are reasonably likely to have a material impact on our liquidity. As of December 31, 2015, the Company has no material commitments or long-term debt for capital expenditures

Recent Accounting Pronouncements

See Note 1 of Notes to Consolidated Financial Statements for information relating to recent accounting pronouncements.

Capital Resources

Total stockholders’ equity at December 31, 2015 was $172,114, an increase of $5,811, or 3.49%, from the $166,303 at December 31, 2014. The largest component of 2015 stockholders’ equity was retained earnings of $171,353, which included net income of $15,833, offset by dividends of $7,930. Stock options exercised in 2015 provided $173. Total stockholders’ equity increased by $20,411 or 13.99%, from $145,892 on December 31, 2013 to $166,303 on December 31, 2014.

The Tier I and Tier II risk-based capital ratios at December 31, 2015 were 24.38% and 25.53%, respectively. Capital ratios are significantly above the regulatory minimum requirements of 6% for Tier I and 8% for Tier II. The Tier I and Tier II risk-based capital ratios at December 31, 2014 were 23.69% and 24.88%, respectively.

Off-Balance Sheet Arrangements

The Company’s off-balance sheet arrangements at December 31, 2015 are detailed in the table below.

	Payments Due by Period
	Total		Less Than 1 Year		1-3 Years		4-5 Years		More Than 5 Years
Commitments to extend credit	$	125,934	$	125,934	$	---	$	---	$	---
Standby letters of credit		15,248		15,248		---		---		---
Mortgage loans with potential recourse		17,571		17,571		---		---		---
Operating leases		972		266		488		218		---
Total	$	159,725	$	159,019	$	488	$	218	$	---

In the normal course of business the Company’s banking affiliate extends lines of credit to its customers. Amounts drawn upon these lines vary at any given time depending on the business needs of the customers.

Standby letters of credit are also issued to the bank’s customers. There are two types of standby letters of credit. The first is a guarantee of payment to facilitate customer purchases. The second type is a performance letter of credit that guarantees a payment if the customer fails to perform a specific obligation. Revenue from these letters was approximately $40 in 2015.

While it would be possible for customers to draw in full on approved lines of credit and letters of credit, historically this has not occurred. In the event of a sudden and substantial draw on these lines, the Company has its own lines of credit from which it can draw funds. A sale of loans or investments would also be an option.

The Company sells mortgages on the secondary market for which there are recourse agreements should the borrower default. The mortgages originated must meet strict underwriting and documentation requirements for the sale to be completed. The Company estimates a potential loss reserve for recourse provisions. The amount is not material as of December 31, 2015. To date, no recourse provisions have been invoked.

Operating leases are for buildings used in the Company’s day-to-day operations.

Notes to Consolidated Financial Statements

$ in thousands, except share data and per share data

Note 1: Summary of Significant Accounting Policies

The consolidated financial statements include the accounts of National Bankshares, Inc. (Bankshares) and its wholly-owned subsidiaries, the National Bank of Blacksburg (NBB), and National Bankshares Financial Services, Inc. (NBFS), (the Company). All significant intercompany balances and transactions have been eliminated in consolidation.

The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America and to general practices within the banking industry. The following is a summary of the more significant accounting policies.

Subsequent events have been considered through the date when the Form 10-K was issued.

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and amounts due from banks.

Interest-Bearing Deposits

The Company invests over-night funds in interest-bearing deposits at other banks, including the Federal Home Loan Bank, the Federal Reserve, and other entities. Interest-bearing deposits are carried at cost.

Securities

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

The Company follows the accounting guidance related to recognition and presentation of other-than-temporary impairment. The guidance specifies that if (a) an entity does not have the intent to sell a debt security prior to recovery and (b) it is more likely than not that the entity will not have to sell the debt security prior to recovery, the security would not be considered other-than-temporarily impaired, unless there is a credit loss. When criteria (a) and (b) are met, the entity will recognize the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. For held-to-maturity debt securities, the amount of an other-than-temporary impairment recorded in other comprehensive income for the noncredit portion of a previous other-than-temporary impairment is amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security.

For equity securities, when the Company has decided to sell an impaired available-for-sale security and the Company does not expect the fair value of the security to fully recover before the expected time of sale, the security is deemed other-than-temporarily impaired in the period in which the decision to sell is made. The Company recognizes an impairment loss when the impairment is deemed other than temporary even if a decision to sell has not been made.

Loans Held for Sale

Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value on an individual loan basis. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Loans held for sale are sold with the mortgage servicing rights released by the Company.

Loans

The Company, through its banking subsidiary, provides mortgage, commercial, and consumer loans to customers. A substantial portion of the loan portfolio is represented by mortgage loans, particularly commercial mortgages. The ability of the Company’s debtors to honor their contracts is dependent upon the real estate and general economic conditions in the Company’s market area.

The Company’s loans are grouped into six segments: real estate construction, consumer real estate, commercial real estate, commercial non real estate, public sector and IDA, and consumer non real estate. Each segment is subject to certain risks that influence the establishment of pricing, loan structures, approval requirements, reserves, and ongoing credit management.

Real estate construction loans are subject to general risks from changing commercial building and housing market trends and economic conditions that may impact demand for completed properties and the costs of completion. Completed properties that do not sell or become leased within originally expected timeframes may impact the borrower’s ability to service the debt. These risks are measured by market-area unemployment rates, bankruptcy rates, housing and commercial building market trends, and interest rates. Risks specific to the borrower are also evaluated, including previous repayment history, debt service ability, and current and projected loan-to value ratios for the collateral.

The credit quality of consumer real estate is subject to risks associated with the borrower’s repayment ability and collateral value, measured generally by analyzing local unemployment and bankruptcy trends, and local housing market trends and interest rates. Risks specific to a borrower are determined by previous repayment history, loan-to-value ratios and debt-to-income ratios.

44

The commercial real estate segment includes loans secured by multifamily residential real estate, commercial real estate occupied by the owner/borrower, and commercial real estate leased to non-owners. Loans in the commercial real estate segment are impacted by economic risks from changing commercial real estate markets, rental markets for multi-family housing and commercial buildings, business bankruptcy rates, local unemployment rates and interest rate trends that would impact the businesses housed by the commercial real estate.

Commercial non real estate loans are secured by collateral other than real estate, or are unsecured. Credit risk for commercial non real estate loans is subject to economic conditions, generally monitored by local business bankruptcy trends, interest rates, and borrower repayment ability and collateral value (if secured).

Public sector and IDA loans are extended to municipalities and related entities. Credit risk is based upon the entity’s ability to repay through either a direct obligation or assignment of specific revenues from an enterprise or other economic activity, and interest rate trends.

Consumer non real estate includes credit cards, automobile and other consumer loans. Credit cards and certain other consumer loans are unsecured, while collateral is obtained for automobile loans and other consumer loans. Credit risk stems primarily from the borrower’s ability to repay. If the loan is secured, the company analyzes loan-to-value ratios. All consumer non real estate loans are analyzed for debt-to-income ratios and previous credit history, as well as for general risks for the portfolio, including local unemployment rates, personal bankruptcy rates and interest rates.

Risks from delinquency trends and characteristics such as second-lien position and interest-only status, as well as historical charge-off rates, are analyzed for all segments.

Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, generally are reported at their outstanding unpaid principal balances adjusted for the allowance for loan losses and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method.

The Company considers multiple factors when determining whether to discontinue accrual of interest on individual loans. Generally loans are placed in nonaccrual status when collection of interest and/or full principal is considered doubtful. Interest accrual is discontinued at the time a commercial real estate loan or commercial non-real estate loan is 90 days delinquent unless the credit is well secured and in the process of collection. Loans within all loan classes that are not restructured but that are impaired and have an associated impairment loss are placed on nonaccrual unless the borrower is paying as agreed. Restructured loans within all classes that allow the borrower to discontinue payments of principal or interest for more than 90 days are placed on nonaccrual unless the modification provides reasonable assurance of repayment performance and collateral value supports regular underwriting requirements. Restructured loans within all classes that maintain current status for at least a six-month period, including history prior to restructuring, may be returned to accrual status.

All interest accrued but not collected for loans of all classes that are placed on nonaccrual or for loans charged off is reversed against interest income. Any interest payments received on nonaccrual loans of all classes are credited to the principal balance of the loan. Loans of all classes that have been designated nonaccrual are returned to accrual status when all the principal and interest amounts contractually due are current; future payments are reasonably assured; and for loans that financed the sale of OREO property, loan-to-value thresholds are met. The Company reviews nonaccrual loans on an individual loan basis to determine whether future payments are reasonably assured. In order for this criteria to be satisfied, the Company’s evaluation must determine that the underlying cause of the original delinquency or weakness that indicated nonaccrual status has been resolved, such as receipt of new guarantees, increased cash flows that cover the debt service or other resolution.

A loan is considered past due when a payment of principal and/or interest is due but not paid. Credit card payments not received within 30 days after the statement date, real estate loan payments not received within the payment cycle; and all other non-real estate secured loans for which payment is not made within the required payment cycle are considered 30 days past due. Management closely monitors past due loans in timeframes of 30-89 days past due and 90 or more days past due.

Allowance for Loan Losses

The allowance for loan losses represents management’s estimate of probable losses inherent in the Company’s loan portfolio. A provision for estimated losses is charged to earnings to establish and maintain the allowance for loan losses at a level reflective of the estimated credit risk. When management determines that a loan balance or portion of a loan balance is not collectible, the loss is charged against the allowance. Subsequent recoveries, if any, are credited to the allowance.

Management evaluates the allowance each quarter through a methodology that estimates losses on individual impaired loans and evaluates the effect of numerous factors on the credit risk of groups of homogeneous loans.

Specific allowances are established for individually-evaluated impaired loans based on the excess of the loan balance relative to the fair value of the loan. Impaired loans are designated as such when current information indicates that it is probable that the Company will be unable to collect principal or interest when due according to the contractual terms of the loan agreement. Loan relationships exceeding $250,000 in nonaccrual status or that are significantly past due, or for which a credit review identified weaknesses that indicate principal and interest will not be collected according to the loan terms, as well as all loans modified in a troubled debt restructuring, are designated impaired. This policy is applicable to all loan classes.

45

Fair value of impaired loans is estimated in one of three ways: (1) the estimated fair value (less selling costs) of the underlying collateral, (2) the present value of the loan’s expected future cash flows, or (3) the loan’s observable market value. The amount of recorded investment (unpaid principal net of any interest payments made by the borrower during the nonaccrual period and net of any partial charge-offs, accrued interest and deferred fees and costs) in an impaired loan that exceeds the fair value is accrued as estimated loss in the allowance. Impaired loans for which collection of interest or principal is in doubt are placed in nonaccrual status.

General allowances are established for collectively-evaluated loans. Collectively-evaluated loans are grouped into classes based on similar characteristics. Factors considered in determining general allowances include net charge-off trends, internal risk ratings, delinquency and nonperforming rates, product mix, underwriting practices, industry trends and economic trends.

The Company’s charge-off policy meets or is more stringent than the minimum standards required by regulators. When available information confirms that a specific loan or a portion thereof, within any loan class, is uncollectible the amount is charged off against the allowance for loan losses. Additionally, losses on consumer real estate and consumer non-real estate loans are typically charged off no later than when the loans are 120-180 days past due, and losses on loans secured by residential real estate or by commercial real estate are charged off by the time the loans reach 180 days past due, in compliance with regulatory guidelines. Accordingly, secured loans may be charged down to the estimated value of the collateral, with previously accrued unpaid interest reversed. Subsequent charge-offs may be required as a result of changes in the market value of collateral or other repayment prospects.

Troubled Debt Restructurings (“TDRs”)

In situations where, for economic or legal reasons related to a borrower’s financial condition, management grants a concession to the borrower that it would not otherwise consider, the related loan is classified as a troubled debt restructuring (TDR). These modified terms may include reduction of the interest rate, extension of the maturity date at an interest rate lower than the current market rate for a new loan with similar risk, forgiveness of principal or accrued interest or other actions intended to minimize the economic loss. TDR loans are individually measured for impairment.

Rate Lock Commitments

The Company enters into commitments to originate mortgage loans in which the interest rate on the loan is determined prior to funding (rate lock commitments). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. The period of time between issuance of a loan commitment and closing and sale of the loan generally ranges from 30 to 60 days. The Company protects itself from changes in interest rates through the use of best efforts forward delivery commitments, by committing to sell a loan at the time the borrower commits to an interest rate with the intent that the buyer has assumed interest rate risk on the loan. As a result, the Company is not exposed to losses nor will it realize significant gains related to its rate lock commitments due to changes in interest rates. The correlation between the rate lock commitments and the best efforts contracts is very high due to their similarity.

The market value of rate lock commitments and best efforts contracts is not readily ascertainable with precision because rate lock commitments and best effort contracts are not actively traded in stand-alone markets. The Company determines the fair value of rate lock commitments and best efforts contracts by measuring the changes in the value of the underlying assets while taking into consideration the probability that the rate lock commitments will close. Because of the high correlation between rate lock commitments and best efforts contracts, no gain or loss occurs on the rate lock commitments.

Premises and Equipment

Land is carried at cost. Premises and equipment are stated at cost, net of accumulated depreciation. Depreciation is charged to expense over the estimated useful lives of the assets on the straight-line basis. Depreciable lives include 40 years for premises, 3-10 years for furniture and equipment, and 3 years for computer software. Costs of maintenance and repairs are charged to expense as incurred and improvements are capitalized.

Other Real Estate Owned

Real estate acquired through or in lieu of foreclosure is held for sale and is initially recorded at fair value less estimated costs to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less estimated costs to sell. Revenue and expenses from operations and changes in the valuation allowance are included in other operating expenses.

Intangible Assets and Goodwill

The Company records as goodwill the excess of purchase price over the fair value of the identifiable net assets acquired. Goodwill is subject to at least an annual assessment for impairment by applying a fair value based test. The Company performs its annual analysis as of September 30 of each fiscal year. Accounting guidance permits preliminary assessment of qualitative factors to determine whether more substantial impairment testing is required. The Company chose to bypass the preliminary assessment and utilized a two-step process for impairment testing of goodwill. The first step tests for impairment, while the second step, if necessary, measures the impairment.

46

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 NBI, while the third technique uses current market pricing multiples for change-of-control transactions involving companies comparable to NBI. 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.

Each measure indicated that the Company’s fair value exceeded its book value. No indicators of impairment for goodwill were identified during the years ended December 31, 2015, 2014, and 2013.

Acquired intangible assets (such as core deposit intangibles) are recognized separately from goodwill if the benefit of the asset can be sold, transferred, licensed, rented, or exchanged, and amortized over its useful life. The Company amortizes on a straight-line basis intangible assets arising from branch purchase transactions over their useful lives, generally ten to twelve years. Core deposit intangibles are subject to a recoverability test based on undiscounted cash flows, and to the impairment recognition and measurement provisions required for other long-lived assets held and used. The impairment testing showed that the expected cash flows of the intangible assets exceeded the carrying value.

Stock-Based Compensation

The Company’s 1999 Stock Option Plan terminated on March 9, 2009. Incentive stock options, all of which are now vested, were granted in the early years of the Plan. The Company recognized the cost of employment services received in exchange for awards of equity instruments based on the fair value of those awards on the date of grant. Compensation cost was recognized over the award’s required service period, which was the vesting period.

Pension Plan

The Company recognizes the overfunded or underfunded status of a defined benefit postretirement plan as an asset or liability in its statement of financial position and recognizes changes in that funded status in the year in which the changes occur through comprehensive income. The funded status of a benefit plan is measured as the difference between plan assets at fair value and the projected benefit obligation.

Income Taxes

Income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur.

Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.

The Company recognizes interest and penalties on income taxes as a component of income tax expense.

Trust Assets and Income

Assets (other than cash deposits) held by the Trust Department in a fiduciary or agency capacity for customers are not included in the consolidated financial statements since such items are not assets of the Company. Trust income is recognized on the accrual basis.

47

Earnings Per Common Share

Basic earnings per common share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate solely to stock options outstanding during the period and are determined using the treasury stock method.

The following shows the weighted average number of shares used in computing earnings per common share and the effect on the weighted average number of shares of dilutive potential common stock.

	2015		2014		2013
Average number of common shares outstanding		6,953,849		6,948,789		6,947,974
Effect of dilutive options		3,245		10,345		20,419
Average number of common shares outstanding used to calculate diluted earnings per common share		6,957,094		6,959,134		6,968,393

The computation of diluted net income per common share excludes shares for stock options that would be anti-dilutive. There were no anti-dilutive shares in 2015, 2014 or 2013.

Loss Contingencies

Loss contingencies, including claims and legal actions arising in the ordinary course of business are recorded as liabilities when the likelihood of loss is probable and reasonably estimated. Management does not believe there are such matters that will have a material effect on the financial statements.

Advertising

The Company charges advertising costs to expenses as incurred. In 2015, the Company expensed $105, and expensed $174 and $194 in 2014 and 2013, respectively.

Use of Estimates

In preparing consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of foreclosed real estate, other-than-temporary impairments of securities, evaluation of impairment of goodwill and other intangibles, and pension obligations.

Changing economic conditions, adverse economic prospects for borrowers, as well as regulatory agency action as a result of examination, could cause NBB to recognize additions to the allowance for loan losses and may also affect the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans.

Certain reclassifications have been made to prior period balances to conform to the current year provisions.

Recent Accounting Pronouncements

In June 2014, the FASB issued ASU No. 2014-12, “Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” The new guidance applies to reporting entities that grant employees share-based payments in which the terms of the award allow a performance target to be achieved after the requisite service period. The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. Existing guidance in “Compensation – Stock Compensation (Topic 718),” should be applied to account for these types of awards. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted and reporting entities may choose to apply the amendments in the ASU either on a prospective or retrospective basis. The Company does not expect the adoption of ASU 2014-12 to have a material impact on its consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” This update is intended to provide guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management is required under the new guidance to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued when preparing financial statements for each interim and annual reporting period. If conditions or events are identified, the ASU specifies the process that must be followed by management and also clarifies the timing and content of going concern footnote disclosures in order to reduce diversity in practice. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-15 to have a material impact on its consolidated financial statements.

48

In November 2014, the FASB issued ASU No. 2014-16, “Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity.” The amendments in ASU do not change the current criteria in U.S. GAAP for determining when separation of certain embedded derivative features in a hybrid financial instrument is required. The amendments clarify how current U.S. GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of the host contract. Furthermore, the amendments clarify that no single term or feature would necessarily determine the economic characteristics and risks of the host contract. Rather, the nature of the host contract depends upon the economic characteristics and risks of the entire hybrid financial instrument. The amendments in this ASU also clarify that, in evaluating the nature of a host contract, an entity should assess the substance of the relevant terms and features (i.e., the relative strength of the debt-like or equity-like terms and features given the facts and circumstances) when considering how to weight those terms and features. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption, including adoption in an interim period, is permitted. The Company does not expect the adoption of ASU 2014-16 to have a material impact on its consolidated financial statements.

In January 2015, the FASB issued ASU No. 2015-01, “Income Statement—Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” The amendments in this ASU eliminate from U.S. GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. If an event or transaction meets the criteria for extraordinary classification, an entity is required to segregate the extraordinary item from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. The entity also is required to disclose applicable income taxes and either present or disclose earnings-per-share data applicable to the extraordinary item. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect the adoption of ASU 2015-01 to have a material impact on its consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” The amendments in this ASU are intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). In addition to reducing the number of consolidation models from four to two, the new standard simplifies the FASB Accounting Standards Codification™ and improves current GAAP by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE), and changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. ASU 2015-02 may be applied retrospectively in previously issued financial statements for one or more years with a cumulative-effect adjustment to retained earnings as of the beginning of the first year restated. The Company does not expect the adoption of ASU 2015-02 to have a material impact on its consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, “Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The amendments in this ASU are intended to simplify the presentation of debt issuance costs. These amendments require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. The amendments in this ASU are effective for public business entities for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. The Company does not expect the adoption of ASU 2015-03 to have a material impact on its consolidated financial statements.

49

In April 2015, the FASB issued ASU No. 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” The amendments in this ASU provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments do not change the accounting for a customer’s accounting for service contracts. As a result of the amendments, all software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. The amendments in this ASU are effective for public business entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. An entity can elect to adopt the amendments either: (1) prospectively to all arrangements entered into or materially modified after the effective date; or (2) retrospectively. The Company does not expect the adoption of ASU 2015-05 to have a material impact on its consolidated financial statements.

In May 2015, the FASB issued ASU No. 2015-08, “Business Combinations (Topic 805): Pushdown Accounting – Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115.” The amendments in ASU 2015-08 amend various SEC paragraphs pursuant to the issuance of Staff Accounting Bulletin No. 115, Topic 5: Miscellaneous Accounting, regarding various pushdown accounting issues, and did not have a material impact on our consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-12, “Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), and Health and Welfare Benefit Plans (Topic 965) – 1. Fully Benefit-Responsive Investment Contracts, 2. Plan Investment Disclosures, and 3. Measurement Date Practical Expedient.” The amendments within this ASU are in 3 parts. Among other things, Part 1 amendments designate contract value as the only required measure for fully benefit-responsive investment contracts; Part II amendments eliminate the requirement that plans disclose: (a) individual investments that represent 5 percent or more of net assets available for benefits; and (b) the net appreciation or depreciation for investments by general type requirements for both participant-directed investments and nonparticipant-directed investments. Part III amendments provide a practical expedient to permit plans to measure investments and investment-related accounts (e.g., a liability for a pending trade with a broker) as of a month-end date that is closest to the plan’s fiscal year-end, when the fiscal period does not coincide with month-end. The amendments in Parts 1 and 2 of this ASU are effective on a retrospective basis and Part 3 is effective on a prospective basis, for fiscal years beginning after December 15, 2015. Early adoption is permitted. The Company does not expect the adoption of ASU 2015-12 to have a material impact on its consolidated financial statements.

In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date.” The amendments in ASU 2015-14 defer the effective date of ASU 2014-09 for all entities by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. All other entities may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities also may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, and interim reporting periods within annual reporting periods beginning one year after the annual reporting period in which the entity first applies the guidance in ASU 2014-09. The Company does not expect the adoption of ASU 2015-14 (or ASU 2014-09) to have a material impact on its consolidated financial statements.

In August 2015, the FASB issued ASU 2015-15, “Interest – Imputation of Interest (Subtopic 835-30) – Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements (Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting).” On April 7, 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires entities to present debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability. The guidance in ASU 2015-03 (see paragraph 835-30-45-1A) does not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff stated that they would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-15 adds these SEC comments to the "S" section of the Codification. The adoption of ASU 2015-15 did not have a material impact on our consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments.” The amendments in ASU 2015-16 require that an acquirer recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed at the acquisition date. The amendments also require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the estimated amounts had been recognized as of the acquisition date. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. The amendments should be applied prospectively to adjustments to provisional amounts that occur after the effective date with earlier application permitted for financial statements that have not been issued. The Company does not expect the adoption of ASU 2015-16 to have a material impact on its consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in ASU 2016-01, among other things: 1) Requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. 2) Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 3) Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). 4) Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently assessing the impact that ASU 2016-01 will have on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-01, “Leases (Topic 842).” Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) A lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU 2016-02 will have on its consolidated financial statements.

The Company had 209 securities with a fair value of $192,125 that were temporarily impaired at December 31, 2015.  The total unrealized loss on these securities was $5,814. Of the temporarily impaired total, 106 securities with a fair value of $95,447 and an unrealized loss of $3,698 have been in a continuous loss position for twelve months or more. The Company has determined that these securities are temporarily impaired at December 31, 2015 for the reasons set out below.

U.S. Government agencies.   The unrealized losses of $5,129 on US Government agency securities stemmed from 178 securities with a fair value of $173,214. The unrealized losses were caused by interest rate and market fluctuations. The contractual terms of the investments do not permit the issuer to settle the securities at a price less than the cost basis of each investment. The Company is monitoring bond market trends and developing strategies to address unrealized losses. Because the Company does not intend to sell any of the investments and it is not likely that the Company will be required to sell any of the investments before recovery of its amortized cost basis, which may be at maturity, the Company does not consider these investments to be other-than-temporarily impaired.

States and political subdivisions. This category’s unrealized losses of $330 on 23 securities with a fair value of $13,610 are primarily the result of interest rate and market fluctuations. The contractual terms of the investments do not permit the issuer to settle the securities at a price less than the cost basis of each investment. Because the Company does not intend to sell any of the investments and it is not likely that the Company will be required to sell any of the investments before recovery of its amortized cost basis, which may be at maturity, the Company does not consider these investments to be other-than-temporarily impaired.

53

Corporate. The Company’s unrealized losses of $293 on 7 corporate debt securities with a fair value of $5,174 are related to interest rate and market fluctuations. The contractual terms of the investments do not permit the issuer to settle the securities at a price less than the cost basis of each investment. Because the Company does not intend to sell any of the investments before recovery of its amortized cost basis, which may be at maturity, the Company does not consider these investments to be other-than-temporarily impaired.

Other securities. The Company holds a small investment in community bank stock. One security with a fair value of $127 has an unrealized loss of $62. The value of this investment has been negatively affected by market conditions. Because the Company does not intend to sell this investment before recovery of its amortized cost basis, the Company does not consider this investment to be other-than-temporarily impaired.    

Restricted stock. Restricted stock is reported separately from available-for-sale securities and held-to-maturity securities. As a member of the Federal Reserve and the Federal Home Loan Bank (“FHLB”) of Atlanta, NBB is required to maintain certain minimum investments in the common stock of those entities. Required levels of investment are based upon NBB’s capital and a percentage of qualifying assets. In addition, NBB is eligible to borrow from the FHLB with borrowings collateralized by qualifying assets, primarily residential mortgage loans totaling approximately $440,062 at December 31, 2015, and NBB’s capital stock investment in the FHLB. Redemption of FHLB stock is subject to certain limitations and conditions. At its discretion, the FHLB may declare dividends on the stock. Management reviews for impairment based upon the ultimate recoverability of the cost basis of the FHLB stock, and at December 31, 2015, management did not determine any impairment.

Management regularly monitors the credit quality of the investment portfolio. Changes in ratings are noted and follow-up research on the issuer is undertaken when warranted. Management intends to carefully monitor any changes in bond quality.

At December 31, 2015 and 2014, securities with a carrying value of $156,721 and $157,951, respectively, were pledged to secure municipal deposits and for other purposes as required or permitted by law.

Note 4: Related Party Transactions

In the ordinary course of business, the Company, through its banking subsidiary, has granted loans to related parties, including executive officers and directors of Bankshares and its subsidiaries. Total funded advances extended to related parties amounted to $8,657 at December 31, 2015 and $6,628 at December 31, 2014. During the year ended December 31, 2015, total principal additions were $4,052 and principal payments were $2,023.The Company held $11,275 in deposits for related parties as of December 31, 2015.

Note 5: Allowance for Loan Losses, Nonperforming Assets and Impaired Loans

The allowance for loan losses methodology incorporates individual evaluation of impaired loans and collective evaluation of groups of non-impaired loans. The Company performs ongoing analysis of the loan portfolio to determine credit quality and to identify impaired loans. Credit quality is rated based on the loan’s payment history, the borrower’s current financial situation and value of the underlying collateral.

Impaired loans are those loans that have been modified in a troubled debt restructure (“TDR” or “restructure”) and larger, non-homogeneous loans that are in nonaccrual or exhibit payment history or financial status that indicate the probability that collection will not occur when due according to the loan’s terms. Generally, impaired loans are given risk ratings that indicate higher risk, such as “classified” or “other assets especially mentioned.” Impaired loans are individually evaluated to determine appropriate reserves and are measured at the lower of the invested amount or the fair value. Impaired loans that are not troubled debt restructures and for which fair value measurement indicates an impairment loss are designated nonaccrual. A restructured loan that maintains current status for at least six months may be in accrual status.

Troubled debt restructurings impact the estimation of the appropriate level of the allowance for loan losses. If the restructuring included forgiveness of a portion of principal or accrued interest, the charge-off is included in the historical charge-off rates applied to the collective evaluation methodology. Further, restructured loans are individually evaluated for impairment, with amounts below fair value accrued in the allowance for loan losses. TDRs that experience a payment default are examined to determine whether the default indicates collateral dependency or cash flows below those that were included in the fair value measurement. TDRs, as well as all impaired loans, that are determined to be collateral dependent are charged down to fair value. Deficiencies indicated by impairment measurements for TDRs that are not collateral dependent may be accrued in the allowance for loan losses or charged off if deemed uncollectible.

The Company evaluated characteristics in the loan portfolio and determined major segments and smaller classes within each segment. These characteristics include collateral type, repayment sources, and (if applicable) the borrower’s business model. The methodology for calculating reserves for collectively-evaluated loans is applied at the class level.

54

Portfolio Segments and Classes

The segments and classes used in determining the allowance for loan losses, beginning in 2013 are as follows.

Real Estate Construction	Commercial Non Real Estate
Construction, residential	Commercial and Industrial
Construction, other
	Public Sector and IDA
Consumer Real Estate	Public sector and IDA
Equity lines
Residential closed-end first liens	Consumer Non Real Estate
Residential closed-end junior liens	Credit cards
Investor-owned residential real estate	Automobile
	Other consumer loans
Commercial Real Estate
Multifamily real estate
Commercial real estate, owner-occupied
Commercial real estate, other

Historical Loss Rates

The Company’s allowance methodology for collectively-evaluated loans applies historical loss rates by class to current class balances as part of the process of determining required reserves. Class loss rates are calculated as the net charge-offs for the class as a percentage of average class balance. The Company averages loss rates for the most recent 8 quarters to determine the historical loss rate for each class.

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

Risk Factors

In addition to historical loss rates, risk factors pertinent to credit risk for each class are analyzed to estimate reserves for collectively-evaluated loans. Factors include changes in national and local economic and business conditions, the nature and volume of classes within the portfolio, loan quality, loan officers’ experience, lending policies and the Company’s loan review system.

The analysis of certain factors results in standard allocations to all segments and classes. These factors include loan officers’ average years of experience, the risk from changes in loan review, unemployment levels, bankruptcy rates, interest rate environment, and competition. Factors analyzed for each class, with resultant allocations based upon the level of risk assessed for each class, include the risk from changes in lending policies, levels of past due loans, nonaccrual loans, current class balance as a percentage of total loans, and the percentage of high risk loans within the class. Additionally, factors specific to each segment are analyzed and result in allocations to the segment. Please refer to Note 1: Summary of Significant Accounting Policies for a discussion of risk factors pertinent to each class.

Real estate construction loans are subject to general risks from changing commercial building and housing market trends and economic conditions that may impact demand for completed properties and the costs of completion. These risks are measured by market-area unemployment rates, bankruptcy rates, housing and commercial building market trends, and interest rates.

The credit quality of consumer real estate is subject to risks associated with the borrower’s repayment ability and collateral value, measured generally by analyzing local unemployment and bankruptcy trends, local housing market trends, and interest rates.

The commercial real estate segment includes loans secured by multifamily residential real estate, commercial real estate occupied by the owner/borrower, and commercial real estate leased to non-owners. Loans in the commercial real estate segment are impacted by economic risks from changing commercial real estate markets, rental markets for multi-family housing and commercial buildings, business bankruptcy rates, local unemployment and interest rate trends that would impact the businesses housed by the commercial real estate.

Commercial non real estate loans are secured by collateral other than real estate, or are unsecured. Credit risk for commercial non real estate loans is subject to economic conditions, generally monitored by local business bankruptcy trends, and interest rates. Public sector and IDA loans are extended to municipalities and related entities. Credit risk is based upon the entity’s ability to repay and interest rate trends.

Consumer non real estate includes credit cards, automobile and other consumer loans. Credit cards and certain other consumer loans are unsecured, while collateral is obtained for automobile loans and other consumer loans. Credit risk stems primarily from the borrower’s ability to repay, measured by average unemployment, average personal bankruptcy rates and interest rates.

55

Factor allocations applied to each class are increased for loans rated special mention and increased to a greater extent for loans rated classified. The Company allocates additional reserves for “high risk” loans. High risk loans include junior liens, interest only and high loan to value loans.

The estimate of credit risk for non-impaired loans is obtained by applying allocations for internal and external factors. The allocations are increased for loans that exhibit greater credit quality risk.

Credit quality indicators, which the Company terms risk grades, are assigned through the Company’s credit review function for larger loans and selective review of loans that fall below credit review thresholds. Loans that do not indicate heightened risk are graded as “pass.” Loans that appear to have elevated credit risk because of frequent or persistent past due status, which is less than 75 days, or that show weakness in the borrower’s financial condition are risk graded “special mention.” Loans with frequent or persistent delinquency exceeding 75 days or that have a higher level of weakness in the borrower’s financial condition are graded “classified.” Classified loans have regulatory risk ratings of “substandard” and “doubtful.” Allocations are increased by 50% and by 100% for loans with grades of “special mention” and “classified,” respectively.

Determination of risk grades was completed for the portfolio as of December 31, 2015, 2014 and 2013.

Sales, Purchases and Reclassification of Loans

The Company finances mortgages under “best efforts” contracts with mortgage purchasers. The mortgages are designated as held for sale upon initiation. There have been no major reclassifications from portfolio loans to held for sale. Occasionally, the Company purchases or sells participations in loans. All participation loans purchased met the Company’s normal underwriting standards at the time the participation was entered. Participation loans are included in the appropriate portfolio balances to which the allowance methodology is applied.

Troubled Debt Restructurings

From time to time the Company modifies loans in troubled debt restructurings (“TDRs”). The following tables present restructurings by class that occurred during the years ended December 31, 2015 and 2014.

Note: Only classes with restructured loans are presented.

	Restructurings that occurred during the year ended December 31, 2015
	Number of Contracts		Pre- Modification Outstanding Recorded Investment		Post- Modification Outstanding Recorded Investment(1)

Total		6	$	3,628	$	3,541

(1) Post-modification outstanding recorded investment considers amounts immediately following the modification. Amounts do not reflect balances at the end of the period.

During the twelve-month period ended December 31, 2015, the Company modified six loans in troubled debt restructurings in order to provide payment relief. One commercial real estate owner-occupied loan was restructured to forgive principal of $100, reduce the interest rate, capitalize interest and re-amortize payments. The fair value measurement of the restructured loan as of December 31, 2015 resulted in no specific allocation to the allowance for loan losses. Two commercial real estate owner-occupied loans were modified during the fourth quarter of 2015 to require payments of interest only. As of December 31, 2015, the impairment analysis determined a combined allocation to the allowance for loan losses of $23. Two construction loans were modified during the fourth quarter of 2015 to become non-revolving and require payments of interest only. The fair value measurement of the restructured loans as of December 31, 2015 resulted in no specific allocation to the allowance for loan losses. One commercial loan was restructured during the fourth quarter of 2015 to extend the maturity date. The fair value measurement of the restructured loan as of December 31, 2015 resulted in no specific allocation to the allowance for loan losses.

During the year ended December 31, 2014, the Company modified five loans in troubled debt restructurings. Each restructuring provided payment relief to the borrower without forgiveness of principal or accrued interest. Each restructuring included a reduction in interest rates. Interest was capitalized at time of restructuring on the residential real estate loan, commercial real estate owner occupied loan, and the two commercial real estate non-owner occupied loans. The multifamily real estate loan, commercial real estate owner occupied loan and residential real estate loan received re-amortization of payments over a longer term. Two commercial real estate non owner occupied loans received a change in payment structure from amortizing to one year of interest-only payments. Each of the loans restructured in 2014 are designated nonaccrual, with the exception of the residential real estate loan which met the criteria for accrual status. The fair value measurements of the restructured loans as of December 31, 2014 resulted in specific allocations to the allowance for loan losses totaling $206.

Of the Company’s TDR’s that defaulted in 2015 and 2014, none were modified within 12 months prior to default. The company defines default as one or more payments that occur more than 90 days past the due date, charge-off or foreclosure subsequent to modification.

Note 8: Employee Benefit Plans

401(k) Plan

The Company has a Retirement Accumulation Plan qualifying under IRS Code Section 401(k), in which NBI, NBB and NBFS are participating employers. Eligible participants may contribute up to 100% of their total annual compensation to the plan, subject to certain limits based on federal tax laws. Employee contributions are matched by the employer based on a percentage of an employee’s total annual compensation contributed to the plan. For the years ended December 31, 2015, 2014 and 2013, the Company contributed $294, $273 and $282, respectively, to the plan.

67

Employee Stock Ownership Plan

The Company has a nonleveraged Employee Stock Ownership Plan (ESOP) which enables employees of NBI and its subsidiaries who have one year of service and who have attained the age of 21 prior to the plan’s January 1 and July 1 enrollment dates to own NBI common stock. Contributions to the ESOP, which are not mandatory, are determined annually by the Board of Directors. Contribution expense amounted to $200, $100 and $275 in the years ended December 31, 2015, 2014 and 2013, respectively. Dividends on ESOP shares are charged to retained earnings. As of December 31, 2015, the number of shares held by the ESOP was 240,874. All shares held by the ESOP are treated as outstanding in computing the Company’s basic net income per share. Upon reaching age 55 with ten years of plan participation, a vested participant has the right to diversify 50% of his or her allocated ESOP shares and NBI or the ESOP, with the agreement of the Trustee, is obligated to purchase those shares. The ESOP contains a put option which allows a withdrawing participant to require the Company or the ESOP, if the plan administrator agrees, to purchase his or her allocated shares if the shares are not readily tradable on an established market at the time of distribution.

Salary Continuation Plan

The Company has a Salary Continuation Plan for certain key officers. The plan provides the participating officers with supplemental retirement income, payable for the greater of 15 years after retirement or the officer’s lifetime. The expense accrued for the plans in 2015, 2014, and 2013, based on the present value of the retirement benefits, amounted to $396, $246, and $194, respectively. The plan is unfunded. However bank-owned life insurance has been acquired on the life of the key employees in amounts sufficient to discharge the obligations of the agreement.

Defined Benefit Plan

The Company’s defined benefit pension plan covers substantially all employees. The plan benefit formula is based upon the length of service of retired employees and a percentage of qualified W-2 compensation during their final years of employment. Information pertaining to activity in the plan is as follows:

Long Term Rate of Return

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

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

The Company, as plan sponsor, has adopted a Pension Administrative Committee Policy (the Policy) for monitoring the investment management of its qualified plans. The Policy includes a statement of general investment principles and a listing of specific investment guidelines, to which the committee may make documented exceptions. The guidelines state that, unless otherwise indicated, all investments that are permitted under the Prudent Investor Rule shall be permissible investments for the defined benefit pension plan. All plan assets are to be invested in marketable securities. Certain investments are prohibited, including commodities and future contracts, private placements, repurchase agreements, options and derivatives. The Policy establishes quality standards for fixed income investments and mutual funds included in the pension plan trust. The Policy also outlines diversification standards.

The preferred target allocation for the assets of the defined benefit pension plan is 65% in equity securities and 35% in fixed income securities. Equity securities include investments in large-cap and mid-cap companies primarily located in the United States, although a small number of international large-cap companies are included. There are also investments in mutual funds holding the equities of large-cap and mid-cap U.S. companies. Fixed income securities include U.S. government agency securities and corporate bonds from companies representing diversified industries. There are no investments in hedge funds, private equity funds or real estate.

Note 9: Stock Option Plan

The Company’s 1999 Stock Option Plan was adopted in 1999 and was terminated on March 9, 2009. Incentive stock options were granted annually to key employees of NBI and its subsidiaries from 1999 to 2005 and none have been granted since 2005. All of the stock options are vested.

A summary of the status of the Company’s stock option plan is presented below:

Options	Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term		Aggregate Intrinsic Value
Outstanding at January 1, 2015		20,500		$	23.00
Granted		---			---
Exercised		(7,500	)		23.00
Forfeited or expired		(13,000	)		23.00
Outstanding at December 31, 2015		---		$	---		---	$	---
Exercisable at December 31, 2015		---		$	---		---	$	---

In 2015, there were 7,500 shares exercised with an intrinsic value of $54. In 2014, there were 2,500 shares exercised with an intrinsic value of $15. There were no shares exercised in 2013. Intrinsic value is the difference between the price at which the shares may be exercised and the stock price as of the report date. No tax benefit was recognized on shares exercised in any of these years.

Note 10: Income Taxes

The Company files United States federal income tax returns, and Virginia, West Virginia and North Carolina state income tax returns. With few exceptions, the Company is no longer subject to U.S. federal, state and local income tax examinations by tax authorities for years prior to 2012.

Allocation of income tax expense between current and deferred portions is as follows:

	Years ended December 31,
	2015		2014		2013
Current	$	4,730	$	5,105	$	5,253
Deferred expense		10		73		64
Total income tax expense	$	4,740	$	5,178	$	5,317

The following is a reconciliation of the “expected” income tax expense, computed by applying the U.S. Federal income tax rate of 35% to income before income tax expense, with the reported income tax expense:

	Years ended December 31,
	2015			2014			2013
Computed “expected” income tax expense	$	7,201		$	7,732		$	8,087
Tax-exempt interest income		(2,381	)		(2,422	)		(2,592	)
Nondeductible interest expense		101			102			118
Other, net		(181	)		(234	)		(296	)
Reported income tax expense	$	4,740		$	5,178		$	5,317

71

The components of net deferred tax assets, included in other assets, are as follows:

	December 31,
	2015			2014
Deferred tax assets:
Allowance for loan losses and unearned fee income	$	3,229		$	3,098
Valuation allowance on other real estate owned		188			37
Deferred compensation and other liabilities		2,829			1,897
Discount accretion of securities		19			28
Net unrealized loss on securities available for sale		1,436			852
Total deferred tax assets	$	7,701		$	5,912
Deferred tax liabilities:
Fixed assets	$	(620	)	$	(160	)
Deposit intangibles		(1,432	)		(1,312	)
Total deferred tax liabilities		(2,052	)		(1,472	)
Net deferred tax assets	$	5,649		$	4,440

The Company has determined that a valuation allowance for the gross deferred tax assets is not necessary at December 31, 2015 and 2014 because the realization of all gross deferred tax assets can be supported by the amount of taxes paid during the carryback period available under current tax laws.

Note 11: Restrictions on Dividends

The Company’s principal source of funds for dividend payments is dividends received from its subsidiary bank. For the years ended December 31, 2015, 2014 and 2013, dividends received from the subsidiary bank were $7,930, $7,853 and $7,782, respectively.

Substantially all of Bankshares’ retained earnings are undistributed earnings of its sole banking subsidiary, which are restricted by various regulations administered by federal bank regulatory agencies. Bank regulatory agencies restrict, without prior approval, the total dividend payments of a bank in any calendar year to the bank’s retained net income of that year to date, as defined, combined with its retained net income of the preceding two years, less any required transfers to surplus. At December 31, 2015, retained net income, which was free of such restriction, amounted to approximately $28,213.

Note 12: Minimum Regulatory Capital Requirement

The Company (on a consolidated basis) and its subsidiary bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

The final rules implementing the Basel Committee on Banking Supervision's capital guidelines for U.S. banks (Basel III rules) became effective on January 1, 2015, with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019.  As part of the new requirements, the Common Equity Tier I Capital ratio is calculated and utilized in the assessment of capital for all institutions.  Capital amounts and ratios for December 31, 2014 were calculated using the Basel I rules, which were effective until January 1, 2015.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the bank to maintain minimum amounts and ratios (set forth in the following table) of total, Tier 1, and Common Equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2015 and 2014, that the Company and the bank meet all capital adequacy requirements to which they are subject.

As of December 31, 2015, the most recent notifications from the Office of the Comptroller of the Currency categorized the bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, Common Equity Tier 1 risk-based and Tier 1 leverage ratios, as set forth in the following tables. There are no conditions or events since these notifications that management believes have changed the bank’s category. The Company’s and the bank’s actual capital amounts and ratios as of December 31, 2015 and 2014 are also presented in the following tables.

Note 14: Financial Instruments with Off-Balance Sheet Risk

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and interest rate locks. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets.

The Company’s exposure to credit loss, in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit, is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company may require collateral or other security to support the following financial instruments with credit risk.

At December 31, 2015 and 2014, the following financial instruments were outstanding whose contract amounts represent credit risk:

	December 31,
	2015		2014
Financial instruments whose contract amounts represent credit risk:
Commitments to extend credit	$	125,934	$	144,578
Standby letters of credit		15,248		14,677
Mortgage loans sold with potential recourse		17,571		10,248

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The commitments for lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if it is deemed necessary by the Company, is based on management’s credit evaluation of the customer.

75

Unfunded commitments under commercial lines of credit, revolving credit lines, and overdraft protection agreements are commitments for possible future extensions of credit. Some of these commitments are uncollateralized and do not contain a specified maturity date and may not be drawn upon to the total extent to which the Company is committed.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, and income-producing commercial properties.

The Company originates mortgage loans for sale to secondary market investors subject to contractually specified and limited recourse provisions. In 2015, the Company originated $17,641 and sold $17,571 to investors, compared to $9,104 originated and $10,248 sold in 2014. Every contract with each investor contains certain recourse language. In general, the Company may be required to repurchase a previously sold mortgage loan if there is major noncompliance with defined loan origination or documentation standards, including fraud, negligence or material misstatement in the loan documents. Repurchase may also be required if necessary governmental loan guarantees are canceled or never issued, or if an investor is forced to buy back a loan after it has been resold as a part of a loan pool. In addition, the Company may have an obligation to repurchase a loan if the mortgagor has defaulted early in the loan term. This potential default period is approximately twelve months after sale of a loan to the investor.

At December 31, 2015, the Company had locked-rate commitments to originate mortgage loans amounting to approximately $179 and loans held for sale of $634. Risks arise from the possible inability of counterparties to meet the terms of their contracts. The Company does not expect any counterparty to fail to meet its obligations.

The Company maintains cash accounts in other commercial banks. The Company had $5 in deposits with correspondent institutions at December 31, 2015 that exceeded the insurance limits of the Federal Deposit Insurance Corporation.

Note 15: Concentrations of Credit Risk

The Company does a general banking business, serving the commercial and personal banking needs of its customers. NBB’s market area in southwest Virginia is made up of the counties of Montgomery, Giles, Pulaski, Tazewell, Wythe, Smyth and Washington. It also includes the independent cities of Radford and Galax, and the portions of Carroll and Grayson Counties that are adjacent to Galax. In addition, it serves those portions of Mercer County and McDowell County, West Virginia that are contiguous with Tazewell County. Substantially all of NBB’s loans are made in its market area. The ultimate collectability of the bank’s loan portfolio and the ability to realize the value of any underlying collateral, if needed, is influenced by the economic conditions of the market area. The Company’s operating results are therefore closely correlated with the economic trends within this area.

Commercial real estate as of December 31, 2015 and 2014 represented approximately 50% and 52% of the loan portfolio, at $309,378 and $310,762, respectively. Included in commercial real estate are loans for college housing and professional office buildings that comprised $200,521 and $190,055 as of December 31, 2015 and 2014 respectively, corresponding to approximately 32% of the loan portfolio at December 31, 2015 and 31% of the loan portfolio at December 31, 2014. Loans secured by residential real estate were $143,504, or approximately 23% of the portfolio, and $147,039, or 24% of the portfolio at December 31, 2015 and 2014, respectively. Loans secured by automobiles represented approximately 2% of the portfolio for both dates, at $12,409 and $11,554 at December 31, 2015 and 2014, respectively.

The Company has established operating policies relating to the credit process and collateral in loan originations. Loans to purchase real and personal property are generally collateralized by the related property and with loan amounts established based on certain percentage limitations of the property’s total stated or appraised value. Credit approval is primarily a function of collateral and the evaluation of the creditworthiness of the individual borrower or project based on available financial information. Management considers the concentration of credit risk to be minimal.

Note 16: Fair Value Measurements

The fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Accounting guidance for fair value excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.     

The Company records fair value adjustments to certain assets and liabilities and determines fair value disclosures utilizing a definition of fair value of assets and liabilities that states that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Additional considerations are involved to determine the fair value of financial assets in markets that are not active.

76

The Company uses a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The three levels of the fair value hierarchy based on these two types of inputs are as follows:

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

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

Securities Available for Sale

Securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Third party vendors compile prices from various sources and may determine the fair value of identical or similar securities by using pricing models that consider observable market data (Level 2). The carrying value of restricted Federal Reserve Bank and Federal Home Loan Bank stock approximates fair value based upon the redemption provisions of each entity and is therefore excluded from the following table.

The following tables present the balances of financial assets measured at fair value on a recurring basis as of December 31, 2015 and 2014:

			Fair Value Measurements at December 31, 2015 Using

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

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

77

Loans Held for Sale

Loans held for sale are carried at the lower of cost or market value. These loans currently consist of one-to-four family residential loans originated for sale in the secondary market. Fair value is based on the price secondary markets are currently offering for similar loans using observable market data which is not materially different than cost due to the short duration between origination and sale (Level 2). As such, the Company records any fair value adjustments on a nonrecurring basis. No nonrecurring fair value adjustments were recorded on loans held for sale during the years ended December 31, 2015 and 2014.

Impaired Loans

Loans are designated as impaired when, in the judgment of management based on current information and events, it is probable that all amounts due will not be collected according to the contractual terms of the loan agreement. Troubled debt restructurings are impaired loans. Impaired loans are measured at fair value on a nonrecurring basis. If an individually-evaluated impaired loan’s balance exceeds fair value, the amount is allocated to the allowance for loan losses. Any fair value adjustments are recorded in the period incurred as provision for loan losses on the Consolidated Statements of Income.

The fair value of an impaired loan and measurement of associated loss is based on one of three methods: the observable market price of the loan, the present value of projected cash flows, or the fair value of the collateral. The observable market price of a loan is categorized as a Level 1 input. The present value of projected cash flows method results in a Level 3 categorization because the calculation relies on the Company’s judgment to determine projected cash flows, which are then discounted at the current rate of the loan, or the rate prior to modification if the loan is a troubled debt restructure.

Loans measured using the fair value of collateral method may be categorized in Level 2 or Level 3. Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable. Most collateral is real estate. The Company bases collateral method fair valuation upon the “as-is” value of independent appraisals or evaluations. Valuations for impaired loans with outstanding principal balances of $250 or more are based on a current appraisal. Appraisals are also used to value impaired loans with principal balances of $100 or greater and secured by one piece of collateral. Collateral-method impaired loans with principal balances below $100, or if secured by multiple pieces of collateral, below $250, are valued using an internal evaluation.

The value of real estate collateral is determined by a current (less than 12 months of age) appraisal or internal evaluation utilizing an income or market valuation approach. Appraisals conducted by an independent, licensed appraiser outside of the Company using observable market data is categorized as Level 2. If a current appraisal cannot be obtained prior to a reporting date and an existing appraisal is discounted to obtain an estimated value, or if declines in value are identified after the date of the appraisal, or if an appraisal is discounted for estimated selling costs, the valuation of real estate collateral is categorized as Level 3. Valuations derived from internal evaluations are categorized as Level 3. The value of business equipment is based upon an outside appraisal (Level 2) if deemed significant, or the net book value on the applicable business’ financial statements (Level 3) if not considered significant. Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (Level 3).

As of December 31, 2015, the fair value measurements for impaired loans with specific allocations were primarily based upon the present value of expected future cash flows. As of December 31, 2014, the fair value measurements for impaired loans with specific allocations were primarily based upon the present value of expected future cash flows, with one loan valued based on the fair value of collateral.

The following table summarizes the Company’s financial assets that were measured at fair value on a nonrecurring basis during the period.

				Carrying value
Date	Description	Balance		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
	Assets:
December 31, 2015	Impaired loans net of valuation allowance	$	2,328	$	---	$	---	$	2,328
December 31, 2014	Impaired loans net of valuation allowance		7,224		---		---		7,224

The following table presents information about Level 3 Fair Value Measurements for December 31, 2015.

	Valuation Technique	Unobservable Input	Range (Weighted Average)
Impaired loans	Present value of cash flows	Discount rate	6.00%	-	7.38%	(6.56%)

The following table presents information about Level 3 Fair Value Measurements for December 31, 2014.

	Valuation Technique	Unobservable Input	Range (Weighted Average)
Impaired loans	Discounted appraised value	Selling cost(1)		10%(2)
Impaired loans	Present value of cash flows	Discount rate	5.88%	-	9.50%	(6.15%)

(1)	Impaired loans that are collateral-dependent are valued using the fair value of collateral. The valuation is discounted for selling costs if repayment of the loan is dependent on the sale of the collateral. If repayment will come from rental income of the property, the valuation is not discounted for selling costs.
(2)	Only one loan was valued using the collateral method as of December 31, 2014.

Other Real Estate Owned

Certain assets such as other real estate owned (OREO) are measured at fair value less cost to sell. Valuation of other real estate owned is determined using current appraisals from independent parties, a level two input. If current appraisals cannot be obtained prior to reporting dates, or if declines in value are identified after a recent appraisal is received, appraisal values are discounted, resulting in Level 3 estimates. If the Company markets the property with a realtor, estimated selling costs reduce the fair value, resulting in a valuation based on Level 3 inputs.

The following table summarizes the Company’s other real estate owned that were measured at fair value on a nonrecurring basis during the period.

				Carrying Value
Date	Description	Balance		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
	Assets:

December 31, 2014	Other real estate owned net of valuation allowance		4,744		---		---		4,744

The following table presents information about Level 3 Fair Value Measurements for December 31, 2015.

	Valuation Technique	Unobservable Input	Range (Weighted Average)
Other real estate owned	Discounted appraised value	Selling cost	0%(1)	-	10.00%	(5.89%)
Other real estate owned	Discounted appraised value	Discount for lack of marketability and age of appraisal	0%	-	50.01%	(10.16%)

The following table presents information about Level 3 Fair Value Measurements for December 31, 2014.

	Valuation Technique	Unobservable Input	Range (Weighted Average)
Other real estate owned	Discounted appraised value	Selling cost	0%(1)	-	11%	(8.60%)
Other real estate owned	Discounted appraised value	Discount for lack of marketability and age of appraisal	0%	-	48.77%	(20.81%)

(1) The Company markets other real estate owned both independently and with local realtors. Properties marketed by realtors are discounted by selling costs. Properties that the Company markets independently are not discounted by selling costs.

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

Cash and Due from Bank, and Interest-Bearing Deposits

The carrying amounts approximate fair value.

Securities

The fair values of securities, excluding restricted stock, are determined by quoted market prices or dealer quotes. The fair value of certain state and municipal securities is not readily available through market sources other than dealer quotations, so fair value estimates are based on quoted market prices of similar instruments adjusted for differences between the quoted instruments and the instruments being valued. The carrying value of restricted securities approximates fair value based upon the redemption provisions of the applicable entities.

Loans Held for Sale

Fair values of loans held for sale are based on commitments on hand from investors or prevailing market prices.

Loans

Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, real estate – commercial, real estate – construction, real estate – mortgage, credit card and other consumer loans. Each loan category is further segmented into fixed and adjustable rate interest terms and by performing and nonperforming categories.

The fair value of performing loans is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan, as well as estimates for prepayments. The estimate of maturity is based on the Company’s historical experience with repayments for loan classification, modified, as required, by an estimate of the effect of economic conditions on lending.

Fair value for significant nonperforming loans is based on estimated cash flows which are discounted using a rate commensurate with the risk associated with the estimated cash flows. Assumptions regarding credit risk, cash flows and discount rates are determined within management’s judgment, using available market information and specific borrower information.

Bank-Owned Life Insurance

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

Deposits

The fair value of demand and savings deposits is the amount payable on demand. The fair value of fixed maturity term deposits and certificates of deposit is estimated using the rates currently offered for deposits with similar remaining maturities.

Accrued Interest

The carrying amounts of accrued interest approximate fair value.

Commitments to Extend Credit and Standby Letters of Credit

The only amounts recorded for commitments to extend credit, standby letters of credit and financial guarantees written are the deferred fees arising from these unrecognized financial instruments. These deferred fees are not deemed significant at December 31, 2015 and 2014, and, as such, the related fair values have not been estimated.

The estimated fair values, and related carrying amounts, of the Company’s financial instruments are as follows:

	December 31, 2015
			Estimated Fair Value
	Carrying Amount		Level 1		Level 2		Level 3

Note 18. Intangible Assets and Goodwill

In accounting for goodwill and intangible assets, the Company conducts an impairment review at least annually and more frequently if certain impairment indicators are in evidence. Accounting guidance provides the option of performing a preliminary assessment of qualitative factors before performing more substantial testing for impairment. If the preliminary assessment indicates that it is more likely than not that fair value is below carrying value, a two-step test is employed to determine impairment. The Company opted not to perform the preliminary assessment and employed the two-step test to determine impairment. Based on the testing for impairment of goodwill and intangible assets, there were no impairment charges for 2015, 2014 or 2013.

Information concerning goodwill and intangible assets for years ended December 31, 2015 and 2014 is presented in the following table:

	Gross Carrying Value		Accumulated Amortization		Net Carrying Value

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of National Bankshares, Inc. and subsidiaries as of December 31, 2015 and 2014, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), National Bankshares, Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated March 9, 2016 expressed an unqualified opinion on the effectiveness of National Bankshares, Inc. and subsidiaries’ internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders

National Bankshares, Inc.

Blacksburg, Virginia

We have audited National Bankshares, Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. National Bankshares, Inc. and subsidiaries’ management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

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

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

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

In our opinion, National Bankshares, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets as of December 31, 2015 and 2014, and the related consolidated statements of income, comprehensive income, changes in stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2015 of National Bankshares, Inc. and subsidiaries and our report dated March 9, 2016 expressed an unqualified opinion.

Item 9. Changes In and Disagreements With Accountants on Accounting and Financial Disclosure

None

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

The Company's management evaluated, with the participation of the Company's principal executive officer and principal financial officer, the effectiveness of the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of the end of the period covered by this report. Based on that evaluation, the Company's principal executive officer and principal financial officer concluded that the Company's disclosure controls and procedures are effective as of December 31, 2015 to ensure that information required to be disclosed in the reports that the Company files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified by the Company's management, including the Company's principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

There were no changes in the Company's internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the year ended December 31, 2015 that have materially affected, or are reasonably likely to materially affect, the Corporation's internal control over financial reporting.

Because of the inherent limitations in all control systems, the Company believes that no system of controls, no matter how well designed and operated, can provide absolute assurance that all control issues have been detected.

Internal Control Over Financial Reporting

 Management's Report on Internal Control Over Financial Reporting

To the Stockholders of National Bankshares, Inc.:

Management is responsible for the preparation and fair presentation of the financial statements included in this annual report. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America and reflect management's judgments and estimates concerning effects of events and transactions that are accounted for or disclosed.

Management is also responsible for establishing and maintaining adequate internal control over financial reporting. The Company's internal control over financial reporting includes those policies and procedures that pertain to the Company's ability to record, process, summarize and report reliable financial data. Management recognizes that there are inherent limitations in the effectiveness of any internal control over financial reporting, including the possibility of human error and the circumvention or overriding of internal control. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Further, because of changes in conditions, the effectiveness of internal control over financial reporting may vary over time.

In order to ensure that the Company's internal control over financial reporting is effective, management regularly assesses such controls and did so most recently for its financial reporting as of December 31, 2015. This assessment was based on criteria for effective internal control over financial reporting described in Internal Control Integrated Framework issued by the Committee of Sponsoring Organizations (COSO, 2013) of the Treadway Commission. Based on this assessment, management believes the Company maintained effective internal control over financial reporting as of December 31, 2015.

The Board of Directors, acting through its Audit Committee, is responsible for the oversight of the Company's accounting policies, financial reporting and internal control. The Audit Committee of the Board of Directors is comprised entirely of outside directors who are independent of management. The Audit Committee is responsible for the appointment and compensation of the independent registered public accounting firm and approves decisions regarding the appointment or removal of the Company Auditor. It meets periodically with management, the independent registered public accounting firm and the internal auditors to ensure that they are carrying out their responsibilities. The Audit Committee is also responsible for performing an oversight role by reviewing and monitoring the financial, accounting and auditing procedures of the Company in addition to reviewing the Company's financial reports. The independent registered public accounting firm and the internal auditors have full and unlimited access to the Audit Committee, with or without management, to discuss the adequacy of internal control over financial reporting, and any other matter which they believe should be brought to the attention of the Audit Committee. The Company's independent registered public accounting firm has also issued an attestation report on the effectiveness of internal control over financial reporting.

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

Note 1: Summary of Significant Accounting Policies

The consolidated financial statements include the accounts of National Bankshares, Inc. (Bankshares) and its wholly-owned subsidiaries, the National Bank of Blacksburg (NBB), and National Bankshares Financial Services, Inc. (NBFS), (the Company). All significant intercompany balances and transactions have been eliminated in consolidation.

The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America and to general practices within the banking industry. The following is a summary of the more significant accounting policies.

Subsequent events have been considered through the date when the Form 10-K was issued.

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and amounts due from banks.

Interest-Bearing Deposits

The Company invests over-night funds in interest-bearing deposits at other banks, including the Federal Home Loan Bank, the Federal Reserve, and other entities. Interest-bearing deposits are carried at cost.

Securities

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

The Company follows the accounting guidance related to recognition and presentation of other-than-temporary impairment. The guidance specifies that if (a) an entity does not have the intent to sell a debt security prior to recovery and (b) it is more likely than not that the entity will not have to sell the debt security prior to recovery, the security would not be considered other-than-temporarily impaired, unless there is a credit loss. When criteria (a) and (b) are met, the entity will recognize the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. For held-to-maturity debt securities, the amount of an other-than-temporary impairment recorded in other comprehensive income for the noncredit portion of a previous other-than-temporary impairment is amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security.

For equity securities, when the Company has decided to sell an impaired available-for-sale security and the Company does not expect the fair value of the security to fully recover before the expected time of sale, the security is deemed other-than-temporarily impaired in the period in which the decision to sell is made. The Company recognizes an impairment loss when the impairment is deemed other than temporary even if a decision to sell has not been made.

Loans Held for Sale

Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value on an individual loan basis. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Loans held for sale are sold with the mortgage servicing rights released by the Company.

Loans

The Company, through its banking subsidiary, provides mortgage, commercial, and consumer loans to customers. A substantial portion of the loan portfolio is represented by mortgage loans, particularly commercial mortgages. The ability of the Company’s debtors to honor their contracts is dependent upon the real estate and general economic conditions in the Company’s market area.

The Company’s loans are grouped into six segments: real estate construction, consumer real estate, commercial real estate, commercial non real estate, public sector and IDA, and consumer non real estate. Each segment is subject to certain risks that influence the establishment of pricing, loan structures, approval requirements, reserves, and ongoing credit management.

Real estate construction loans are subject to general risks from changing commercial building and housing market trends and economic conditions that may impact demand for completed properties and the costs of completion. Completed properties that do not sell or become leased within originally expected timeframes may impact the borrower’s ability to service the debt. These risks are measured by market-area unemployment rates, bankruptcy rates, housing and commercial building market trends, and interest rates. Risks specific to the borrower are also evaluated, including previous repayment history, debt service ability, and current and projected loan-to value ratios for the collateral.

The credit quality of consumer real estate is subject to risks associated with the borrower’s repayment ability and collateral value, measured generally by analyzing local unemployment and bankruptcy trends, and local housing market trends and interest rates. Risks specific to a borrower are determined by previous repayment history, loan-to-value ratios and debt-to-income ratios.

The commercial real estate segment includes loans secured by multifamily residential real estate, commercial real estate occupied by the owner/borrower, and commercial real estate leased to non-owners. Loans in the commercial real estate segment are impacted by economic risks from changing commercial real estate markets, rental markets for multi-family housing and commercial buildings, business bankruptcy rates, local unemployment rates and interest rate trends that would impact the businesses housed by the commercial real estate.

Commercial non real estate loans are secured by collateral other than real estate, or are unsecured. Credit risk for commercial non real estate loans is subject to economic conditions, generally monitored by local business bankruptcy trends, interest rates, and borrower repayment ability and collateral value (if secured).

Public sector and IDA loans are extended to municipalities and related entities. Credit risk is based upon the entity’s ability to repay through either a direct obligation or assignment of specific revenues from an enterprise or other economic activity, and interest rate trends.

Consumer non real estate includes credit cards, automobile and other consumer loans. Credit cards and certain other consumer loans are unsecured, while collateral is obtained for automobile loans and other consumer loans. Credit risk stems primarily from the borrower’s ability to repay. If the loan is secured, the company analyzes loan-to-value ratios. All consumer non real estate loans are analyzed for debt-to-income ratios and previous credit history, as well as for general risks for the portfolio, including local unemployment rates, personal bankruptcy rates and interest rates.

Risks from delinquency trends and characteristics such as second-lien position and interest-only status, as well as historical charge-off rates, are analyzed for all segments.

Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, generally are reported at their outstanding unpaid principal balances adjusted for the allowance for loan losses and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method.

The Company considers multiple factors when determining whether to discontinue accrual of interest on individual loans. Generally loans are placed in nonaccrual status when collection of interest and/or full principal is considered doubtful. Interest accrual is discontinued at the time a commercial real estate loan or commercial non-real estate loan is 90 days delinquent unless the credit is well secured and in the process of collection. Loans within all loan classes that are not restructured but that are impaired and have an associated impairment loss are placed on nonaccrual unless the borrower is paying as agreed. Restructured loans within all classes that allow the borrower to discontinue payments of principal or interest for more than 90 days are placed on nonaccrual unless the modification provides reasonable assurance of repayment performance and collateral value supports regular underwriting requirements. Restructured loans within all classes that maintain current status for at least a six-month period, including history prior to restructuring, may be returned to accrual status.

All interest accrued but not collected for loans of all classes that are placed on nonaccrual or for loans charged off is reversed against interest income. Any interest payments received on nonaccrual loans of all classes are credited to the principal balance of the loan. Loans of all classes that have been designated nonaccrual are returned to accrual status when all the principal and interest amounts contractually due are current; future payments are reasonably assured; and for loans that financed the sale of OREO property, loan-to-value thresholds are met. The Company reviews nonaccrual loans on an individual loan basis to determine whether future payments are reasonably assured. In order for this criteria to be satisfied, the Company’s evaluation must determine that the underlying cause of the original delinquency or weakness that indicated nonaccrual status has been resolved, such as receipt of new guarantees, increased cash flows that cover the debt service or other resolution.

A loan is considered past due when a payment of principal and/or interest is due but not paid. Credit card payments not received within 30 days after the statement date, real estate loan payments not received within the payment cycle; and all other non-real estate secured loans for which payment is not made within the required payment cycle are considered 30 days past due. Management closely monitors past due loans in timeframes of 30-89 days past due and 90 or more days past due.

Allowance for Loan Losses

The allowance for loan losses represents management’s estimate of probable losses inherent in the Company’s loan portfolio. A provision for estimated losses is charged to earnings to establish and maintain the allowance for loan losses at a level reflective of the estimated credit risk. When management determines that a loan balance or portion of a loan balance is not collectible, the loss is charged against the allowance. Subsequent recoveries, if any, are credited to the allowance.

Management evaluates the allowance each quarter through a methodology that estimates losses on individual impaired loans and evaluates the effect of numerous factors on the credit risk of groups of homogeneous loans.

Specific allowances are established for individually-evaluated impaired loans based on the excess of the loan balance relative to the fair value of the loan. Impaired loans are designated as such when current information indicates that it is probable that the Company will be unable to collect principal or interest when due according to the contractual terms of the loan agreement. Loan relationships exceeding $250,000 in nonaccrual status or that are significantly past due, or for which a credit review identified weaknesses that indicate principal and interest will not be collected according to the loan terms, as well as all loans modified in a troubled debt restructuring, are designated impaired. This policy is applicable to all loan classes.

Fair value of impaired loans is estimated in one of three ways: (1) the estimated fair value (less selling costs) of the underlying collateral, (2) the present value of the loan’s expected future cash flows, or (3) the loan’s observable market value. The amount of recorded investment (unpaid principal net of any interest payments made by the borrower during the nonaccrual period and net of any partial charge-offs, accrued interest and deferred fees and costs) in an impaired loan that exceeds the fair value is accrued as estimated loss in the allowance. Impaired loans for which collection of interest or principal is in doubt are placed in nonaccrual status.

General allowances are established for collectively-evaluated loans. Collectively-evaluated loans are grouped into classes based on similar characteristics. Factors considered in determining general allowances include net charge-off trends, internal risk ratings, delinquency and nonperforming rates, product mix, underwriting practices, industry trends and economic trends.

The Company’s charge-off policy meets or is more stringent than the minimum standards required by regulators. When available information confirms that a specific loan or a portion thereof, within any loan class, is uncollectible the amount is charged off against the allowance for loan losses. Additionally, losses on consumer real estate and consumer non-real estate loans are typically charged off no later than when the loans are 120-180 days past due, and losses on loans secured by residential real estate or by commercial real estate are charged off by the time the loans reach 180 days past due, in compliance with regulatory guidelines. Accordingly, secured loans may be charged down to the estimated value of the collateral, with previously accrued unpaid interest reversed. Subsequent charge-offs may be required as a result of changes in the market value of collateral or other repayment prospects.

Troubled Debt Restructurings (“TDRs”)

In situations where, for economic or legal reasons related to a borrower’s financial condition, management grants a concession to the borrower that it would not otherwise consider, the related loan is classified as a troubled debt restructuring (TDR). These modified terms may include reduction of the interest rate, extension of the maturity date at an interest rate lower than the current market rate for a new loan with similar risk, forgiveness of principal or accrued interest or other actions intended to minimize the economic loss. TDR loans are individually measured for impairment.

Rate Lock Commitments

The Company enters into commitments to originate mortgage loans in which the interest rate on the loan is determined prior to funding (rate lock commitments). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. The period of time between issuance of a loan commitment and closing and sale of the loan generally ranges from 30 to 60 days. The Company protects itself from changes in interest rates through the use of best efforts forward delivery commitments, by committing to sell a loan at the time the borrower commits to an interest rate with the intent that the buyer has assumed interest rate risk on the loan. As a result, the Company is not exposed to losses nor will it realize significant gains related to its rate lock commitments due to changes in interest rates. The correlation between the rate lock commitments and the best efforts contracts is very high due to their similarity.

The market value of rate lock commitments and best efforts contracts is not readily ascertainable with precision because rate lock commitments and best effort contracts are not actively traded in stand-alone markets. The Company determines the fair value of rate lock commitments and best efforts contracts by measuring the changes in the value of the underlying assets while taking into consideration the probability that the rate lock commitments will close. Because of the high correlation between rate lock commitments and best efforts contracts, no gain or loss occurs on the rate lock commitments.

Premises and Equipment

Land is carried at cost. Premises and equipment are stated at cost, net of accumulated depreciation. Depreciation is charged to expense over the estimated useful lives of the assets on the straight-line basis. Depreciable lives include 40 years for premises, 3-10 years for furniture and equipment, and 3 years for computer software. Costs of maintenance and repairs are charged to expense as incurred and improvements are capitalized.

Other Real Estate Owned

Real estate acquired through or in lieu of foreclosure is held for sale and is initially recorded at fair value less estimated costs to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less estimated costs to sell. Revenue and expenses from operations and changes in the valuation allowance are included in other operating expenses.

Intangible Assets and Goodwill

The Company records as goodwill the excess of purchase price over the fair value of the identifiable net assets acquired. Goodwill is subject to at least an annual assessment for impairment by applying a fair value based test. The Company performs its annual analysis as of September 30 of each fiscal year. Accounting guidance permits preliminary assessment of qualitative factors to determine whether more substantial impairment testing is required. The Company chose to bypass the preliminary assessment and utilized a two-step process for impairment testing of goodwill. The first step tests for impairment, while the second step, if necessary, measures the impairment.

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 NBI, while the third technique uses current market pricing multiples for change-of-control transactions involving companies comparable to NBI. 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.

Each measure indicated that the Company’s fair value exceeded its book value. No indicators of impairment for goodwill were identified during the years ended December 31, 2015, 2014, and 2013.

Acquired intangible assets (such as core deposit intangibles) are recognized separately from goodwill if the benefit of the asset can be sold, transferred, licensed, rented, or exchanged, and amortized over its useful life. The Company amortizes on a straight-line basis intangible assets arising from branch purchase transactions over their useful lives, generally ten to twelve years. Core deposit intangibles are subject to a recoverability test based on undiscounted cash flows, and to the impairment recognition and measurement provisions required for other long-lived assets held and used. The impairment testing showed that the expected cash flows of the intangible assets exceeded the carrying value.

Stock-Based Compensation

The Company’s 1999 Stock Option Plan terminated on March 9, 2009. Incentive stock options, all of which are now vested, were granted in the early years of the Plan. The Company recognized the cost of employment services received in exchange for awards of equity instruments based on the fair value of those awards on the date of grant. Compensation cost was recognized over the award’s required service period, which was the vesting period.

Pension Plan

The Company recognizes the overfunded or underfunded status of a defined benefit postretirement plan as an asset or liability in its statement of financial position and recognizes changes in that funded status in the year in which the changes occur through comprehensive income. The funded status of a benefit plan is measured as the difference between plan assets at fair value and the projected benefit obligation.

Income Taxes

Income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur.

Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.

The Company recognizes interest and penalties on income taxes as a component of income tax expense.

Trust Assets and Income

Assets (other than cash deposits) held by the Trust Department in a fiduciary or agency capacity for customers are not included in the consolidated financial statements since such items are not assets of the Company. Trust income is recognized on the accrual basis.

Earnings Per Common Share

Basic earnings per common share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate solely to stock options outstanding during the period and are determined using the treasury stock method.

The following shows the weighted average number of shares used in computing earnings per common share and the effect on the weighted average number of shares of dilutive potential common stock.

	2015		2014		2013
Average number of common shares outstanding		6,953,849		6,948,789		6,947,974
Effect of dilutive options		3,245		10,345		20,419
Average number of common shares outstanding used to calculate diluted earnings per common share		6,957,094		6,959,134		6,968,393

The computation of diluted net income per common share excludes shares for stock options that would be anti-dilutive. There were no anti-dilutive shares in 2015, 2014 or 2013.

Loss Contingencies

Loss contingencies, including claims and legal actions arising in the ordinary course of business are recorded as liabilities when the likelihood of loss is probable and reasonably estimated. Management does not believe there are such matters that will have a material effect on the financial statements.

Advertising

The Company charges advertising costs to expenses as incurred. In 2015, the Company expensed $105, and expensed $174 and $194 in 2014 and 2013, respectively.

Use of Estimates

In preparing consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of foreclosed real estate, other-than-temporary impairments of securities, evaluation of impairment of goodwill and other intangibles, and pension obligations.

Changing economic conditions, adverse economic prospects for borrowers, as well as regulatory agency action as a result of examination, could cause NBB to recognize additions to the allowance for loan losses and may also affect the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans.

Certain reclassifications have been made to prior period balances to conform to the current year provisions.

Recent Accounting Pronouncements

In June 2014, the FASB issued ASU No. 2014-12, “Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” The new guidance applies to reporting entities that grant employees share-based payments in which the terms of the award allow a performance target to be achieved after the requisite service period. The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. Existing guidance in “Compensation – Stock Compensation (Topic 718),” should be applied to account for these types of awards. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted and reporting entities may choose to apply the amendments in the ASU either on a prospective or retrospective basis. The Company does not expect the adoption of ASU 2014-12 to have a material impact on its consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” This update is intended to provide guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management is required under the new guidance to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued when preparing financial statements for each interim and annual reporting period. If conditions or events are identified, the ASU specifies the process that must be followed by management and also clarifies the timing and content of going concern footnote disclosures in order to reduce diversity in practice. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-15 to have a material impact on its consolidated financial statements.

In November 2014, the FASB issued ASU No. 2014-16, “Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity.” The amendments in ASU do not change the current criteria in U.S. GAAP for determining when separation of certain embedded derivative features in a hybrid financial instrument is required. The amendments clarify how current U.S. GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of the host contract. Furthermore, the amendments clarify that no single term or feature would necessarily determine the economic characteristics and risks of the host contract. Rather, the nature of the host contract depends upon the economic characteristics and risks of the entire hybrid financial instrument. The amendments in this ASU also clarify that, in evaluating the nature of a host contract, an entity should assess the substance of the relevant terms and features (i.e., the relative strength of the debt-like or equity-like terms and features given the facts and circumstances) when considering how to weight those terms and features. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption, including adoption in an interim period, is permitted. The Company does not expect the adoption of ASU 2014-16 to have a material impact on its consolidated financial statements.

In January 2015, the FASB issued ASU No. 2015-01, “Income Statement—Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” The amendments in this ASU eliminate from U.S. GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. If an event or transaction meets the criteria for extraordinary classification, an entity is required to segregate the extraordinary item from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. The entity also is required to disclose applicable income taxes and either present or disclose earnings-per-share data applicable to the extraordinary item. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect the adoption of ASU 2015-01 to have a material impact on its consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” The amendments in this ASU are intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). In addition to reducing the number of consolidation models from four to two, the new standard simplifies the FASB Accounting Standards Codification™ and improves current GAAP by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE), and changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. ASU 2015-02 may be applied retrospectively in previously issued financial statements for one or more years with a cumulative-effect adjustment to retained earnings as of the beginning of the first year restated. The Company does not expect the adoption of ASU 2015-02 to have a material impact on its consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, “Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The amendments in this ASU are intended to simplify the presentation of debt issuance costs. These amendments require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. The amendments in this ASU are effective for public business entities for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. The Company does not expect the adoption of ASU 2015-03 to have a material impact on its consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” The amendments in this ASU provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments do not change the accounting for a customer’s accounting for service contracts. As a result of the amendments, all software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. The amendments in this ASU are effective for public business entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. An entity can elect to adopt the amendments either: (1) prospectively to all arrangements entered into or materially modified after the effective date; or (2) retrospectively. The Company does not expect the adoption of ASU 2015-05 to have a material impact on its consolidated financial statements.

In May 2015, the FASB issued ASU No. 2015-08, “Business Combinations (Topic 805): Pushdown Accounting – Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115.” The amendments in ASU 2015-08 amend various SEC paragraphs pursuant to the issuance of Staff Accounting Bulletin No. 115, Topic 5: Miscellaneous Accounting, regarding various pushdown accounting issues, and did not have a material impact on our consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-12, “Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), and Health and Welfare Benefit Plans (Topic 965) – 1. Fully Benefit-Responsive Investment Contracts, 2. Plan Investment Disclosures, and 3. Measurement Date Practical Expedient.” The amendments within this ASU are in 3 parts. Among other things, Part 1 amendments designate contract value as the only required measure for fully benefit-responsive investment contracts; Part II amendments eliminate the requirement that plans disclose: (a) individual investments that represent 5 percent or more of net assets available for benefits; and (b) the net appreciation or depreciation for investments by general type requirements for both participant-directed investments and nonparticipant-directed investments. Part III amendments provide a practical expedient to permit plans to measure investments and investment-related accounts (e.g., a liability for a pending trade with a broker) as of a month-end date that is closest to the plan’s fiscal year-end, when the fiscal period does not coincide with month-end. The amendments in Parts 1 and 2 of this ASU are effective on a retrospective basis and Part 3 is effective on a prospective basis, for fiscal years beginning after December 15, 2015. Early adoption is permitted. The Company does not expect the adoption of ASU 2015-12 to have a material impact on its consolidated financial statements.

In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date.” The amendments in ASU 2015-14 defer the effective date of ASU 2014-09 for all entities by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. All other entities may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities also may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, and interim reporting periods within annual reporting periods beginning one year after the annual reporting period in which the entity first applies the guidance in ASU 2014-09. The Company does not expect the adoption of ASU 2015-14 (or ASU 2014-09) to have a material impact on its consolidated financial statements.

In August 2015, the FASB issued ASU 2015-15, “Interest – Imputation of Interest (Subtopic 835-30) – Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements (Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting).” On April 7, 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires entities to present debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability. The guidance in ASU 2015-03 (see paragraph 835-30-45-1A) does not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff stated that they would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-15 adds these SEC comments to the "S" section of the Codification. The adoption of ASU 2015-15 did not have a material impact on our consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments.” The amendments in ASU 2015-16 require that an acquirer recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed at the acquisition date. The amendments also require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the estimated amounts had been recognized as of the acquisition date. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. The amendments should be applied prospectively to adjustments to provisional amounts that occur after the effective date with earlier application permitted for financial statements that have not been issued. The Company does not expect the adoption of ASU 2015-16 to have a material impact on its consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in ASU 2016-01, among other things: 1) Requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. 2) Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 3) Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). 4) Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently assessing the impact that ASU 2016-01 will have on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-01, “Leases (Topic 842).” Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) A lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU 2016-02 will have on its consolidated financial statements.

The Company had 209 securities with a fair value of $192,125 that were temporarily impaired at December 31, 2015.  The total unrealized loss on these securities was $5,814. Of the temporarily impaired total, 106 securities with a fair value of $95,447 and an unrealized loss of $3,698 have been in a continuous loss position for twelve months or more. The Company has determined that these securities are temporarily impaired at December 31, 2015 for the reasons set out below.

U.S. Government agencies.   The unrealized losses of $5,129 on US Government agency securities stemmed from 178 securities with a fair value of $173,214. The unrealized losses were caused by interest rate and market fluctuations. The contractual terms of the investments do not permit the issuer to settle the securities at a price less than the cost basis of each investment. The Company is monitoring bond market trends and developing strategies to address unrealized losses. Because the Company does not intend to sell any of the investments and it is not likely that the Company will be required to sell any of the investments before recovery of its amortized cost basis, which may be at maturity, the Company does not consider these investments to be other-than-temporarily impaired.

States and political subdivisions. This category’s unrealized losses of $330 on 23 securities with a fair value of $13,610 are primarily the result of interest rate and market fluctuations. The contractual terms of the investments do not permit the issuer to settle the securities at a price less than the cost basis of each investment. Because the Company does not intend to sell any of the investments and it is not likely that the Company will be required to sell any of the investments before recovery of its amortized cost basis, which may be at maturity, the Company does not consider these investments to be other-than-temporarily impaired.

Corporate. The Company’s unrealized losses of $293 on 7 corporate debt securities with a fair value of $5,174 are related to interest rate and market fluctuations. The contractual terms of the investments do not permit the issuer to settle the securities at a price less than the cost basis of each investment. Because the Company does not intend to sell any of the investments before recovery of its amortized cost basis, which may be at maturity, the Company does not consider these investments to be other-than-temporarily impaired.

Other securities. The Company holds a small investment in community bank stock. One security with a fair value of $127 has an unrealized loss of $62. The value of this investment has been negatively affected by market conditions. Because the Company does not intend to sell this investment before recovery of its amortized cost basis, the Company does not consider this investment to be other-than-temporarily impaired.    

Restricted stock. Restricted stock is reported separately from available-for-sale securities and held-to-maturity securities. As a member of the Federal Reserve and the Federal Home Loan Bank (“FHLB”) of Atlanta, NBB is required to maintain certain minimum investments in the common stock of those entities. Required levels of investment are based upon NBB’s capital and a percentage of qualifying assets. In addition, NBB is eligible to borrow from the FHLB with borrowings collateralized by qualifying assets, primarily residential mortgage loans totaling approximately $440,062 at December 31, 2015, and NBB’s capital stock investment in the FHLB. Redemption of FHLB stock is subject to certain limitations and conditions. At its discretion, the FHLB may declare dividends on the stock. Management reviews for impairment based upon the ultimate recoverability of the cost basis of the FHLB stock, and at December 31, 2015, management did not determine any impairment.

Management regularly monitors the credit quality of the investment portfolio. Changes in ratings are noted and follow-up research on the issuer is undertaken when warranted. Management intends to carefully monitor any changes in bond quality.

At December 31, 2015 and 2014, securities with a carrying value of $156,721 and $157,951, respectively, were pledged to secure municipal deposits and for other purposes as required or permitted by law.

Note 5 - Allowance for Loan Losses, Nonperforming Assets and Impaired Loans

Disclosure Text Block Supplement [Abstract]

Allowance for Credit Losses [Text Block]

Note 5: Allowance for Loan Losses, Nonperforming Assets and Impaired Loans

The allowance for loan losses methodology incorporates individual evaluation of impaired loans and collective evaluation of groups of non-impaired loans. The Company performs ongoing analysis of the loan portfolio to determine credit quality and to identify impaired loans. Credit quality is rated based on the loan’s payment history, the borrower’s current financial situation and value of the underlying collateral.

Impaired loans are those loans that have been modified in a troubled debt restructure (“TDR” or “restructure”) and larger, non-homogeneous loans that are in nonaccrual or exhibit payment history or financial status that indicate the probability that collection will not occur when due according to the loan’s terms. Generally, impaired loans are given risk ratings that indicate higher risk, such as “classified” or “other assets especially mentioned.” Impaired loans are individually evaluated to determine appropriate reserves and are measured at the lower of the invested amount or the fair value. Impaired loans that are not troubled debt restructures and for which fair value measurement indicates an impairment loss are designated nonaccrual. A restructured loan that maintains current status for at least six months may be in accrual status.

Troubled debt restructurings impact the estimation of the appropriate level of the allowance for loan losses. If the restructuring included forgiveness of a portion of principal or accrued interest, the charge-off is included in the historical charge-off rates applied to the collective evaluation methodology. Further, restructured loans are individually evaluated for impairment, with amounts below fair value accrued in the allowance for loan losses. TDRs that experience a payment default are examined to determine whether the default indicates collateral dependency or cash flows below those that were included in the fair value measurement. TDRs, as well as all impaired loans, that are determined to be collateral dependent are charged down to fair value. Deficiencies indicated by impairment measurements for TDRs that are not collateral dependent may be accrued in the allowance for loan losses or charged off if deemed uncollectible.

The Company evaluated characteristics in the loan portfolio and determined major segments and smaller classes within each segment. These characteristics include collateral type, repayment sources, and (if applicable) the borrower’s business model. The methodology for calculating reserves for collectively-evaluated loans is applied at the class level.

Portfolio Segments and Classes

The segments and classes used in determining the allowance for loan losses, beginning in 2013 are as follows.

Real Estate Construction	Commercial Non Real Estate
Construction, residential	Commercial and Industrial
Construction, other
	Public Sector and IDA
Consumer Real Estate	Public sector and IDA
Equity lines
Residential closed-end first liens	Consumer Non Real Estate
Residential closed-end junior liens	Credit cards
Investor-owned residential real estate	Automobile
	Other consumer loans
Commercial Real Estate
Multifamily real estate
Commercial real estate, owner-occupied
Commercial real estate, other

Historical Loss Rates

The Company’s allowance methodology for collectively-evaluated loans applies historical loss rates by class to current class balances as part of the process of determining required reserves. Class loss rates are calculated as the net charge-offs for the class as a percentage of average class balance. The Company averages loss rates for the most recent 8 quarters to determine the historical loss rate for each class.

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

Risk Factors

In addition to historical loss rates, risk factors pertinent to credit risk for each class are analyzed to estimate reserves for collectively-evaluated loans. Factors include changes in national and local economic and business conditions, the nature and volume of classes within the portfolio, loan quality, loan officers’ experience, lending policies and the Company’s loan review system.

The analysis of certain factors results in standard allocations to all segments and classes. These factors include loan officers’ average years of experience, the risk from changes in loan review, unemployment levels, bankruptcy rates, interest rate environment, and competition. Factors analyzed for each class, with resultant allocations based upon the level of risk assessed for each class, include the risk from changes in lending policies, levels of past due loans, nonaccrual loans, current class balance as a percentage of total loans, and the percentage of high risk loans within the class. Additionally, factors specific to each segment are analyzed and result in allocations to the segment. Please refer to Note 1: Summary of Significant Accounting Policies for a discussion of risk factors pertinent to each class.

Real estate construction loans are subject to general risks from changing commercial building and housing market trends and economic conditions that may impact demand for completed properties and the costs of completion. These risks are measured by market-area unemployment rates, bankruptcy rates, housing and commercial building market trends, and interest rates.

The credit quality of consumer real estate is subject to risks associated with the borrower’s repayment ability and collateral value, measured generally by analyzing local unemployment and bankruptcy trends, local housing market trends, and interest rates.

The commercial real estate segment includes loans secured by multifamily residential real estate, commercial real estate occupied by the owner/borrower, and commercial real estate leased to non-owners. Loans in the commercial real estate segment are impacted by economic risks from changing commercial real estate markets, rental markets for multi-family housing and commercial buildings, business bankruptcy rates, local unemployment and interest rate trends that would impact the businesses housed by the commercial real estate.

Commercial non real estate loans are secured by collateral other than real estate, or are unsecured. Credit risk for commercial non real estate loans is subject to economic conditions, generally monitored by local business bankruptcy trends, and interest rates. Public sector and IDA loans are extended to municipalities and related entities. Credit risk is based upon the entity’s ability to repay and interest rate trends.

Consumer non real estate includes credit cards, automobile and other consumer loans. Credit cards and certain other consumer loans are unsecured, while collateral is obtained for automobile loans and other consumer loans. Credit risk stems primarily from the borrower’s ability to repay, measured by average unemployment, average personal bankruptcy rates and interest rates.

Factor allocations applied to each class are increased for loans rated special mention and increased to a greater extent for loans rated classified. The Company allocates additional reserves for “high risk” loans. High risk loans include junior liens, interest only and high loan to value loans.

The estimate of credit risk for non-impaired loans is obtained by applying allocations for internal and external factors. The allocations are increased for loans that exhibit greater credit quality risk.

Credit quality indicators, which the Company terms risk grades, are assigned through the Company’s credit review function for larger loans and selective review of loans that fall below credit review thresholds. Loans that do not indicate heightened risk are graded as “pass.” Loans that appear to have elevated credit risk because of frequent or persistent past due status, which is less than 75 days, or that show weakness in the borrower’s financial condition are risk graded “special mention.” Loans with frequent or persistent delinquency exceeding 75 days or that have a higher level of weakness in the borrower’s financial condition are graded “classified.” Classified loans have regulatory risk ratings of “substandard” and “doubtful.” Allocations are increased by 50% and by 100% for loans with grades of “special mention” and “classified,” respectively.

Determination of risk grades was completed for the portfolio as of December 31, 2015, 2014 and 2013.

The following displays non-impaired gross loans by credit quality indicator:

Sales, Purchases and Reclassification of Loans

The Company finances mortgages under “best efforts” contracts with mortgage purchasers. The mortgages are designated as held for sale upon initiation. There have been no major reclassifications from portfolio loans to held for sale. Occasionally, the Company purchases or sells participations in loans. All participation loans purchased met the Company’s normal underwriting standards at the time the participation was entered. Participation loans are included in the appropriate portfolio balances to which the allowance methodology is applied.

Troubled Debt Restructurings

From time to time the Company modifies loans in troubled debt restructurings (“TDRs”). The following tables present restructurings by class that occurred during the years ended December 31, 2015 and 2014.

Note: Only classes with restructured loans are presented.

	Restructurings that occurred during the year ended December 31, 2015
	Number of Contracts		Pre- Modification Outstanding Recorded Investment		Post- Modification Outstanding Recorded Investment(1)

Total		6	$	3,628	$	3,541

(1) Post-modification outstanding recorded investment considers amounts immediately following the modification. Amounts do not reflect balances at the end of the period.

During the twelve-month period ended December 31, 2015, the Company modified six loans in troubled debt restructurings in order to provide payment relief. One commercial real estate owner-occupied loan was restructured to forgive principal of $100, reduce the interest rate, capitalize interest and re-amortize payments. The fair value measurement of the restructured loan as of December 31, 2015 resulted in no specific allocation to the allowance for loan losses. Two commercial real estate owner-occupied loans were modified during the fourth quarter of 2015 to require payments of interest only. As of December 31, 2015, the impairment analysis determined a combined allocation to the allowance for loan losses of $23. Two construction loans were modified during the fourth quarter of 2015 to become non-revolving and require payments of interest only. The fair value measurement of the restructured loans as of December 31, 2015 resulted in no specific allocation to the allowance for loan losses. One commercial loan was restructured during the fourth quarter of 2015 to extend the maturity date. The fair value measurement of the restructured loan as of December 31, 2015 resulted in no specific allocation to the allowance for loan losses.

(1) Post-modification outstanding recorded investment considers amounts immediately following the modification. Amounts do not reflect balances at the end of the period.

During the year ended December 31, 2014, the Company modified five loans in troubled debt restructurings. Each restructuring provided payment relief to the borrower without forgiveness of principal or accrued interest. Each restructuring included a reduction in interest rates. Interest was capitalized at time of restructuring on the residential real estate loan, commercial real estate owner occupied loan, and the two commercial real estate non-owner occupied loans. The multifamily real estate loan, commercial real estate owner occupied loan and residential real estate loan received re-amortization of payments over a longer term. Two commercial real estate non owner occupied loans received a change in payment structure from amortizing to one year of interest-only payments. Each of the loans restructured in 2014 are designated nonaccrual, with the exception of the residential real estate loan which met the criteria for accrual status. The fair value measurements of the restructured loans as of December 31, 2014 resulted in specific allocations to the allowance for loan losses totaling $206.

Of the Company’s TDR’s that defaulted in 2015 and 2014, none were modified within 12 months prior to default. The company defines default as one or more payments that occur more than 90 days past the due date, charge-off or foreclosure subsequent to modification.

Note 8: Employee Benefit Plans

401(k) Plan

The Company has a Retirement Accumulation Plan qualifying under IRS Code Section 401(k), in which NBI, NBB and NBFS are participating employers. Eligible participants may contribute up to 100% of their total annual compensation to the plan, subject to certain limits based on federal tax laws. Employee contributions are matched by the employer based on a percentage of an employee’s total annual compensation contributed to the plan. For the years ended December 31, 2015, 2014 and 2013, the Company contributed $294, $273 and $282, respectively, to the plan.

Employee Stock Ownership Plan

The Company has a nonleveraged Employee Stock Ownership Plan (ESOP) which enables employees of NBI and its subsidiaries who have one year of service and who have attained the age of 21 prior to the plan’s January 1 and July 1 enrollment dates to own NBI common stock. Contributions to the ESOP, which are not mandatory, are determined annually by the Board of Directors. Contribution expense amounted to $200, $100 and $275 in the years ended December 31, 2015, 2014 and 2013, respectively. Dividends on ESOP shares are charged to retained earnings. As of December 31, 2015, the number of shares held by the ESOP was 240,874. All shares held by the ESOP are treated as outstanding in computing the Company’s basic net income per share. Upon reaching age 55 with ten years of plan participation, a vested participant has the right to diversify 50% of his or her allocated ESOP shares and NBI or the ESOP, with the agreement of the Trustee, is obligated to purchase those shares. The ESOP contains a put option which allows a withdrawing participant to require the Company or the ESOP, if the plan administrator agrees, to purchase his or her allocated shares if the shares are not readily tradable on an established market at the time of distribution.

Salary Continuation Plan

The Company has a Salary Continuation Plan for certain key officers. The plan provides the participating officers with supplemental retirement income, payable for the greater of 15 years after retirement or the officer’s lifetime. The expense accrued for the plans in 2015, 2014, and 2013, based on the present value of the retirement benefits, amounted to $396, $246, and $194, respectively. The plan is unfunded. However bank-owned life insurance has been acquired on the life of the key employees in amounts sufficient to discharge the obligations of the agreement.

Defined Benefit Plan

The Company’s defined benefit pension plan covers substantially all employees. The plan benefit formula is based upon the length of service of retired employees and a percentage of qualified W-2 compensation during their final years of employment. Information pertaining to activity in the plan is as follows:

Long Term Rate of Return

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

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

The Company, as plan sponsor, has adopted a Pension Administrative Committee Policy (the Policy) for monitoring the investment management of its qualified plans. The Policy includes a statement of general investment principles and a listing of specific investment guidelines, to which the committee may make documented exceptions. The guidelines state that, unless otherwise indicated, all investments that are permitted under the Prudent Investor Rule shall be permissible investments for the defined benefit pension plan. All plan assets are to be invested in marketable securities. Certain investments are prohibited, including commodities and future contracts, private placements, repurchase agreements, options and derivatives. The Policy establishes quality standards for fixed income investments and mutual funds included in the pension plan trust. The Policy also outlines diversification standards.

The preferred target allocation for the assets of the defined benefit pension plan is 65% in equity securities and 35% in fixed income securities. Equity securities include investments in large-cap and mid-cap companies primarily located in the United States, although a small number of international large-cap companies are included. There are also investments in mutual funds holding the equities of large-cap and mid-cap U.S. companies. Fixed income securities include U.S. government agency securities and corporate bonds from companies representing diversified industries. There are no investments in hedge funds, private equity funds or real estate.

Note 9: Stock Option Plan

The Company’s 1999 Stock Option Plan was adopted in 1999 and was terminated on March 9, 2009. Incentive stock options were granted annually to key employees of NBI and its subsidiaries from 1999 to 2005 and none have been granted since 2005. All of the stock options are vested.

A summary of the status of the Company’s stock option plan is presented below:

Options	Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term		Aggregate Intrinsic Value
Outstanding at January 1, 2015		20,500		$	23.00

In 2015, there were 7,500 shares exercised with an intrinsic value of $54. In 2014, there were 2,500 shares exercised with an intrinsic value of $15. There were no shares exercised in 2013. Intrinsic value is the difference between the price at which the shares may be exercised and the stock price as of the report date. No tax benefit was recognized on shares exercised in any of these years.

Note 10: Income Taxes

The Company files United States federal income tax returns, and Virginia, West Virginia and North Carolina state income tax returns. With few exceptions, the Company is no longer subject to U.S. federal, state and local income tax examinations by tax authorities for years prior to 2012.

Allocation of income tax expense between current and deferred portions is as follows:

	Years ended December 31,
	2015		2014		2013
Current	$	4,730	$	5,105	$	5,253
Deferred expense		10		73		64
Total income tax expense	$	4,740	$	5,178	$	5,317

The following is a reconciliation of the “expected” income tax expense, computed by applying the U.S. Federal income tax rate of 35% to income before income tax expense, with the reported income tax expense:

	Years ended December 31,
	2015			2014			2013
Computed “expected” income tax expense	$	7,201		$	7,732		$	8,087
Tax-exempt interest income		(2,381	)		(2,422	)		(2,592	)
Nondeductible interest expense		101			102			118
Other, net		(181	)		(234	)		(296	)
Reported income tax expense	$	4,740		$	5,178		$	5,317

The components of net deferred tax assets, included in other assets, are as follows:

	December 31,
	2015			2014
Deferred tax assets:
Allowance for loan losses and unearned fee income	$	3,229		$	3,098
Valuation allowance on other real estate owned		188			37
Deferred compensation and other liabilities		2,829			1,897
Discount accretion of securities		19			28
Net unrealized loss on securities available for sale		1,436			852
Total deferred tax assets	$	7,701		$	5,912
Deferred tax liabilities:
Fixed assets	$	(620	)	$	(160	)
Deposit intangibles		(1,432	)		(1,312	)
Total deferred tax liabilities		(2,052	)		(1,472	)
Net deferred tax assets	$	5,649		$	4,440

The Company has determined that a valuation allowance for the gross deferred tax assets is not necessary at December 31, 2015 and 2014 because the realization of all gross deferred tax assets can be supported by the amount of taxes paid during the carryback period available under current tax laws.

Note 11: Restrictions on Dividends

The Company’s principal source of funds for dividend payments is dividends received from its subsidiary bank. For the years ended December 31, 2015, 2014 and 2013, dividends received from the subsidiary bank were $7,930, $7,853 and $7,782, respectively.

Substantially all of Bankshares’ retained earnings are undistributed earnings of its sole banking subsidiary, which are restricted by various regulations administered by federal bank regulatory agencies. Bank regulatory agencies restrict, without prior approval, the total dividend payments of a bank in any calendar year to the bank’s retained net income of that year to date, as defined, combined with its retained net income of the preceding two years, less any required transfers to surplus. At December 31, 2015, retained net income, which was free of such restriction, amounted to approximately $28,213.

Note 12 - Minimum Regulatory Capital Requirement

Dec. 31, 2015

Disclosure Text Block [Abstract]

Regulatory Capital Requirements under Banking Regulations [Text Block]

Note 12: Minimum Regulatory Capital Requirement

The Company (on a consolidated basis) and its subsidiary bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

The final rules implementing the Basel Committee on Banking Supervision's capital guidelines for U.S. banks (Basel III rules) became effective on January 1, 2015, with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019.  As part of the new requirements, the Common Equity Tier I Capital ratio is calculated and utilized in the assessment of capital for all institutions.  Capital amounts and ratios for December 31, 2014 were calculated using the Basel I rules, which were effective until January 1, 2015.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the bank to maintain minimum amounts and ratios (set forth in the following table) of total, Tier 1, and Common Equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2015 and 2014, that the Company and the bank meet all capital adequacy requirements to which they are subject.

As of December 31, 2015, the most recent notifications from the Office of the Comptroller of the Currency categorized the bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, Common Equity Tier 1 risk-based and Tier 1 leverage ratios, as set forth in the following tables. There are no conditions or events since these notifications that management believes have changed the bank’s category. The Company’s and the bank’s actual capital amounts and ratios as of December 31, 2015 and 2014 are also presented in the following tables.

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and interest rate locks. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets.

The Company’s exposure to credit loss, in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit, is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company may require collateral or other security to support the following financial instruments with credit risk.

At December 31, 2015 and 2014, the following financial instruments were outstanding whose contract amounts represent credit risk:

	December 31,
	2015		2014
Financial instruments whose contract amounts represent credit risk:
Commitments to extend credit	$	125,934	$	144,578
Standby letters of credit		15,248		14,677
Mortgage loans sold with potential recourse		17,571		10,248

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The commitments for lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if it is deemed necessary by the Company, is based on management’s credit evaluation of the customer.

Unfunded commitments under commercial lines of credit, revolving credit lines, and overdraft protection agreements are commitments for possible future extensions of credit. Some of these commitments are uncollateralized and do not contain a specified maturity date and may not be drawn upon to the total extent to which the Company is committed.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, and income-producing commercial properties.

The Company originates mortgage loans for sale to secondary market investors subject to contractually specified and limited recourse provisions. In 2015, the Company originated $17,641 and sold $17,571 to investors, compared to $9,104 originated and $10,248 sold in 2014. Every contract with each investor contains certain recourse language. In general, the Company may be required to repurchase a previously sold mortgage loan if there is major noncompliance with defined loan origination or documentation standards, including fraud, negligence or material misstatement in the loan documents. Repurchase may also be required if necessary governmental loan guarantees are canceled or never issued, or if an investor is forced to buy back a loan after it has been resold as a part of a loan pool. In addition, the Company may have an obligation to repurchase a loan if the mortgagor has defaulted early in the loan term. This potential default period is approximately twelve months after sale of a loan to the investor.

At December 31, 2015, the Company had locked-rate commitments to originate mortgage loans amounting to approximately $179 and loans held for sale of $634. Risks arise from the possible inability of counterparties to meet the terms of their contracts. The Company does not expect any counterparty to fail to meet its obligations.

The Company maintains cash accounts in other commercial banks. The Company had $5 in deposits with correspondent institutions at December 31, 2015 that exceeded the insurance limits of the Federal Deposit Insurance Corporation.

Note 15: Concentrations of Credit Risk

The Company does a general banking business, serving the commercial and personal banking needs of its customers. NBB’s market area in southwest Virginia is made up of the counties of Montgomery, Giles, Pulaski, Tazewell, Wythe, Smyth and Washington. It also includes the independent cities of Radford and Galax, and the portions of Carroll and Grayson Counties that are adjacent to Galax. In addition, it serves those portions of Mercer County and McDowell County, West Virginia that are contiguous with Tazewell County. Substantially all of NBB’s loans are made in its market area. The ultimate collectability of the bank’s loan portfolio and the ability to realize the value of any underlying collateral, if needed, is influenced by the economic conditions of the market area. The Company’s operating results are therefore closely correlated with the economic trends within this area.

Commercial real estate as of December 31, 2015 and 2014 represented approximately 50% and 52% of the loan portfolio, at $309,378 and $310,762, respectively. Included in commercial real estate are loans for college housing and professional office buildings that comprised $200,521 and $190,055 as of December 31, 2015 and 2014 respectively, corresponding to approximately 32% of the loan portfolio at December 31, 2015 and 31% of the loan portfolio at December 31, 2014. Loans secured by residential real estate were $143,504, or approximately 23% of the portfolio, and $147,039, or 24% of the portfolio at December 31, 2015 and 2014, respectively. Loans secured by automobiles represented approximately 2% of the portfolio for both dates, at $12,409 and $11,554 at December 31, 2015 and 2014, respectively.

The Company has established operating policies relating to the credit process and collateral in loan originations. Loans to purchase real and personal property are generally collateralized by the related property and with loan amounts established based on certain percentage limitations of the property’s total stated or appraised value. Credit approval is primarily a function of collateral and the evaluation of the creditworthiness of the individual borrower or project based on available financial information. Management considers the concentration of credit risk to be minimal.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

Note 16: Fair Value Measurements

The fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Accounting guidance for fair value excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.     

The Company records fair value adjustments to certain assets and liabilities and determines fair value disclosures utilizing a definition of fair value of assets and liabilities that states that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Additional considerations are involved to determine the fair value of financial assets in markets that are not active.

The Company uses a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The three levels of the fair value hierarchy based on these two types of inputs are as follows:

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

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

Securities Available for Sale

Securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Third party vendors compile prices from various sources and may determine the fair value of identical or similar securities by using pricing models that consider observable market data (Level 2). The carrying value of restricted Federal Reserve Bank and Federal Home Loan Bank stock approximates fair value based upon the redemption provisions of each entity and is therefore excluded from the following table.

The following tables present the balances of financial assets measured at fair value on a recurring basis as of December 31, 2015 and 2014:

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

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

Loans Held for Sale

Loans held for sale are carried at the lower of cost or market value. These loans currently consist of one-to-four family residential loans originated for sale in the secondary market. Fair value is based on the price secondary markets are currently offering for similar loans using observable market data which is not materially different than cost due to the short duration between origination and sale (Level 2). As such, the Company records any fair value adjustments on a nonrecurring basis. No nonrecurring fair value adjustments were recorded on loans held for sale during the years ended December 31, 2015 and 2014.

Impaired Loans

Loans are designated as impaired when, in the judgment of management based on current information and events, it is probable that all amounts due will not be collected according to the contractual terms of the loan agreement. Troubled debt restructurings are impaired loans. Impaired loans are measured at fair value on a nonrecurring basis. If an individually-evaluated impaired loan’s balance exceeds fair value, the amount is allocated to the allowance for loan losses. Any fair value adjustments are recorded in the period incurred as provision for loan losses on the Consolidated Statements of Income.

The fair value of an impaired loan and measurement of associated loss is based on one of three methods: the observable market price of the loan, the present value of projected cash flows, or the fair value of the collateral. The observable market price of a loan is categorized as a Level 1 input. The present value of projected cash flows method results in a Level 3 categorization because the calculation relies on the Company’s judgment to determine projected cash flows, which are then discounted at the current rate of the loan, or the rate prior to modification if the loan is a troubled debt restructure.

Loans measured using the fair value of collateral method may be categorized in Level 2 or Level 3. Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable. Most collateral is real estate. The Company bases collateral method fair valuation upon the “as-is” value of independent appraisals or evaluations. Valuations for impaired loans with outstanding principal balances of $250 or more are based on a current appraisal. Appraisals are also used to value impaired loans with principal balances of $100 or greater and secured by one piece of collateral. Collateral-method impaired loans with principal balances below $100, or if secured by multiple pieces of collateral, below $250, are valued using an internal evaluation.

The value of real estate collateral is determined by a current (less than 12 months of age) appraisal or internal evaluation utilizing an income or market valuation approach. Appraisals conducted by an independent, licensed appraiser outside of the Company using observable market data is categorized as Level 2. If a current appraisal cannot be obtained prior to a reporting date and an existing appraisal is discounted to obtain an estimated value, or if declines in value are identified after the date of the appraisal, or if an appraisal is discounted for estimated selling costs, the valuation of real estate collateral is categorized as Level 3. Valuations derived from internal evaluations are categorized as Level 3. The value of business equipment is based upon an outside appraisal (Level 2) if deemed significant, or the net book value on the applicable business’ financial statements (Level 3) if not considered significant. Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (Level 3).

As of December 31, 2015, the fair value measurements for impaired loans with specific allocations were primarily based upon the present value of expected future cash flows. As of December 31, 2014, the fair value measurements for impaired loans with specific allocations were primarily based upon the present value of expected future cash flows, with one loan valued based on the fair value of collateral.

The following table summarizes the Company’s financial assets that were measured at fair value on a nonrecurring basis during the period.

				Carrying value
Date	Description	Balance		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

December 31, 2014	Impaired loans net of valuation allowance		7,224		---		---		7,224

The following table presents information about Level 3 Fair Value Measurements for December 31, 2015.

	Valuation Technique	Unobservable Input	Range (Weighted Average)
Impaired loans	Present value of cash flows	Discount rate	6.00%	-	7.38%	(6.56%)

The following table presents information about Level 3 Fair Value Measurements for December 31, 2014.

Impaired loans	Discounted appraised value	Selling cost(1)		10%
Impaired loans	Present value of cash flows	Discount rate	5.88%	-	9.50%	(6.15%)

(1)	Impaired loans that are collateral-dependent are valued using the fair value of collateral. The valuation is discounted for selling costs if repayment of the loan is dependent on the sale of the collateral. If repayment will come from rental income of the property, the valuation is not discounted for selling costs.
(2)	Only one loan was valued using the collateral method as of December 31, 2014.

Other Real Estate Owned

Certain assets such as other real estate owned (OREO) are measured at fair value less cost to sell. Valuation of other real estate owned is determined using current appraisals from independent parties, a level two input. If current appraisals cannot be obtained prior to reporting dates, or if declines in value are identified after a recent appraisal is received, appraisal values are discounted, resulting in Level 3 estimates. If the Company markets the property with a realtor, estimated selling costs reduce the fair value, resulting in a valuation based on Level 3 inputs.

The following table summarizes the Company’s other real estate owned that were measured at fair value on a nonrecurring basis during the period.

				Carrying Value
Date	Description	Balance		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

December 31, 2014	Other real estate owned net of valuation allowance		4,744		---		---		4,744

The following table presents information about Level 3 Fair Value Measurements for December 31, 2015.

	Valuation Technique	Unobservable Input	Range (Weighted Average)
Other real estate owned	Discounted appraised value	Selling cost	0%	-	10.00%	(5.89%)
Other real estate owned	Discounted appraised value	Discount for lack of marketability and age of appraisal	0%	-	50.01%	(10.16%)

The following table presents information about Level 3 Fair Value Measurements for December 31, 2014.

	Valuation Technique	Unobservable Input	Range (Weighted Average)
Other real estate owned	Discounted appraised value	Selling cost	0%	-	11%	(8.60%)
Other real estate owned	Discounted appraised value	Discount for lack of marketability and age of appraisal	0%	-	48.77%	(20.81%)

(1) The Company markets other real estate owned both independently and with local realtors. Properties marketed by realtors are discounted by selling costs. Properties that the Company markets independently are not discounted by selling costs.

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

Cash and Due from Bank, and Interest-Bearing Deposits

The carrying amounts approximate fair value.

Securities

The fair values of securities, excluding restricted stock, are determined by quoted market prices or dealer quotes. The fair value of certain state and municipal securities is not readily available through market sources other than dealer quotations, so fair value estimates are based on quoted market prices of similar instruments adjusted for differences between the quoted instruments and the instruments being valued. The carrying value of restricted securities approximates fair value based upon the redemption provisions of the applicable entities.

Loans Held for Sale

Fair values of loans held for sale are based on commitments on hand from investors or prevailing market prices.

Loans

Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, real estate – commercial, real estate – construction, real estate – mortgage, credit card and other consumer loans. Each loan category is further segmented into fixed and adjustable rate interest terms and by performing and nonperforming categories.

The fair value of performing loans is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan, as well as estimates for prepayments. The estimate of maturity is based on the Company’s historical experience with repayments for loan classification, modified, as required, by an estimate of the effect of economic conditions on lending.

Fair value for significant nonperforming loans is based on estimated cash flows which are discounted using a rate commensurate with the risk associated with the estimated cash flows. Assumptions regarding credit risk, cash flows and discount rates are determined within management’s judgment, using available market information and specific borrower information.

Bank-Owned Life Insurance

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

Deposits

The fair value of demand and savings deposits is the amount payable on demand. The fair value of fixed maturity term deposits and certificates of deposit is estimated using the rates currently offered for deposits with similar remaining maturities.

Accrued Interest

The carrying amounts of accrued interest approximate fair value.

Commitments to Extend Credit and Standby Letters of Credit

The only amounts recorded for commitments to extend credit, standby letters of credit and financial guarantees written are the deferred fees arising from these unrecognized financial instruments. These deferred fees are not deemed significant at December 31, 2015 and 2014, and, as such, the related fair values have not been estimated.

The estimated fair values, and related carrying amounts, of the Company’s financial instruments are as follows:

Note 18. Intangible Assets and Goodwill

In accounting for goodwill and intangible assets, the Company conducts an impairment review at least annually and more frequently if certain impairment indicators are in evidence. Accounting guidance provides the option of performing a preliminary assessment of qualitative factors before performing more substantial testing for impairment. If the preliminary assessment indicates that it is more likely than not that fair value is below carrying value, a two-step test is employed to determine impairment. The Company opted not to perform the preliminary assessment and employed the two-step test to determine impairment. Based on the testing for impairment of goodwill and intangible assets, there were no impairment charges for 2015, 2014 or 2013.

Information concerning goodwill and intangible assets for years ended December 31, 2015 and 2014 is presented in the following table:

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and amounts due from banks.

Interest-bearing Deposits [Policy Text Block]

Interest-Bearing Deposits

The Company invests over-night funds in interest-bearing deposits at other banks, including the Federal Home Loan Bank, the Federal Reserve, and other entities. Interest-bearing deposits are carried at cost.

Marketable Securities, Policy [Policy Text Block]

Securities

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

The Company follows the accounting guidance related to recognition and presentation of other-than-temporary impairment. The guidance specifies that if (a) an entity does not have the intent to sell a debt security prior to recovery and (b) it is more likely than not that the entity will not have to sell the debt security prior to recovery, the security would not be considered other-than-temporarily impaired, unless there is a credit loss. When criteria (a) and (b) are met, the entity will recognize the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. For held-to-maturity debt securities, the amount of an other-than-temporary impairment recorded in other comprehensive income for the noncredit portion of a previous other-than-temporary impairment is amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security.

For equity securities, when the Company has decided to sell an impaired available-for-sale security and the Company does not expect the fair value of the security to fully recover before the expected time of sale, the security is deemed other-than-temporarily impaired in the period in which the decision to sell is made. The Company recognizes an impairment loss when the impairment is deemed other than temporary even if a decision to sell has not been made.

Finance, Loan and Lease Receivables, Held-for-sale, Policy [Policy Text Block]

Loans Held for Sale

Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value on an individual loan basis. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Loans held for sale are sold with the mortgage servicing rights released by the Company.

Finance, Loan and Lease Receivables, Held-for-investment, Policy [Policy Text Block]

Loans

The Company, through its banking subsidiary, provides mortgage, commercial, and consumer loans to customers. A substantial portion of the loan portfolio is represented by mortgage loans, particularly commercial mortgages. The ability of the Company’s debtors to honor their contracts is dependent upon the real estate and general economic conditions in the Company’s market area.

The Company’s loans are grouped into six segments: real estate construction, consumer real estate, commercial real estate, commercial non real estate, public sector and IDA, and consumer non real estate. Each segment is subject to certain risks that influence the establishment of pricing, loan structures, approval requirements, reserves, and ongoing credit management.

Real estate construction loans are subject to general risks from changing commercial building and housing market trends and economic conditions that may impact demand for completed properties and the costs of completion. Completed properties that do not sell or become leased within originally expected timeframes may impact the borrower’s ability to service the debt. These risks are measured by market-area unemployment rates, bankruptcy rates, housing and commercial building market trends, and interest rates. Risks specific to the borrower are also evaluated, including previous repayment history, debt service ability, and current and projected loan-to value ratios for the collateral.

The credit quality of consumer real estate is subject to risks associated with the borrower’s repayment ability and collateral value, measured generally by analyzing local unemployment and bankruptcy trends, and local housing market trends and interest rates. Risks specific to a borrower are determined by previous repayment history, loan-to-value ratios and debt-to-income ratios.

The commercial real estate segment includes loans secured by multifamily residential real estate, commercial real estate occupied by the owner/borrower, and commercial real estate leased to non-owners. Loans in the commercial real estate segment are impacted by economic risks from changing commercial real estate markets, rental markets for multi-family housing and commercial buildings, business bankruptcy rates, local unemployment rates and interest rate trends that would impact the businesses housed by the commercial real estate.

Commercial non real estate loans are secured by collateral other than real estate, or are unsecured. Credit risk for commercial non real estate loans is subject to economic conditions, generally monitored by local business bankruptcy trends, interest rates, and borrower repayment ability and collateral value (if secured).

Public sector and IDA loans are extended to municipalities and related entities. Credit risk is based upon the entity’s ability to repay through either a direct obligation or assignment of specific revenues from an enterprise or other economic activity, and interest rate trends.

Consumer non real estate includes credit cards, automobile and other consumer loans. Credit cards and certain other consumer loans are unsecured, while collateral is obtained for automobile loans and other consumer loans. Credit risk stems primarily from the borrower’s ability to repay. If the loan is secured, the company analyzes loan-to-value ratios. All consumer non real estate loans are analyzed for debt-to-income ratios and previous credit history, as well as for general risks for the portfolio, including local unemployment rates, personal bankruptcy rates and interest rates.

Risks from delinquency trends and characteristics such as second-lien position and interest-only status, as well as historical charge-off rates, are analyzed for all segments.

Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, generally are reported at their outstanding unpaid principal balances adjusted for the allowance for loan losses and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method.

The Company considers multiple factors when determining whether to discontinue accrual of interest on individual loans. Generally loans are placed in nonaccrual status when collection of interest and/or full principal is considered doubtful. Interest accrual is discontinued at the time a commercial real estate loan or commercial non-real estate loan is 90 days delinquent unless the credit is well secured and in the process of collection. Loans within all loan classes that are not restructured but that are impaired and have an associated impairment loss are placed on nonaccrual unless the borrower is paying as agreed. Restructured loans within all classes that allow the borrower to discontinue payments of principal or interest for more than 90 days are placed on nonaccrual unless the modification provides reasonable assurance of repayment performance and collateral value supports regular underwriting requirements. Restructured loans within all classes that maintain current status for at least a six-month period, including history prior to restructuring, may be returned to accrual status.

All interest accrued but not collected for loans of all classes that are placed on nonaccrual or for loans charged off is reversed against interest income. Any interest payments received on nonaccrual loans of all classes are credited to the principal balance of the loan. Loans of all classes that have been designated nonaccrual are returned to accrual status when all the principal and interest amounts contractually due are current; future payments are reasonably assured; and for loans that financed the sale of OREO property, loan-to-value thresholds are met. The Company reviews nonaccrual loans on an individual loan basis to determine whether future payments are reasonably assured. In order for this criteria to be satisfied, the Company’s evaluation must determine that the underlying cause of the original delinquency or weakness that indicated nonaccrual status has been resolved, such as receipt of new guarantees, increased cash flows that cover the debt service or other resolution.

A loan is considered past due when a payment of principal and/or interest is due but not paid. Credit card payments not received within 30 days after the statement date, real estate loan payments not received within the payment cycle; and all other non-real estate secured loans for which payment is not made within the required payment cycle are considered 30 days past due. Management closely monitors past due loans in timeframes of 30-89 days past due and 90 or more days past due.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]

Allowance for Loan Losses

The allowance for loan losses represents management’s estimate of probable losses inherent in the Company’s loan portfolio. A provision for estimated losses is charged to earnings to establish and maintain the allowance for loan losses at a level reflective of the estimated credit risk. When management determines that a loan balance or portion of a loan balance is not collectible, the loss is charged against the allowance. Subsequent recoveries, if any, are credited to the allowance.

Management evaluates the allowance each quarter through a methodology that estimates losses on individual impaired loans and evaluates the effect of numerous factors on the credit risk of groups of homogeneous loans.

Specific allowances are established for individually-evaluated impaired loans based on the excess of the loan balance relative to the fair value of the loan. Impaired loans are designated as such when current information indicates that it is probable that the Company will be unable to collect principal or interest when due according to the contractual terms of the loan agreement. Loan relationships exceeding $250,000 in nonaccrual status or that are significantly past due, or for which a credit review identified weaknesses that indicate principal and interest will not be collected according to the loan terms, as well as all loans modified in a troubled debt restructuring, are designated impaired. This policy is applicable to all loan classes.

Fair value of impaired loans is estimated in one of three ways: (1) the estimated fair value (less selling costs) of the underlying collateral, (2) the present value of the loan’s expected future cash flows, or (3) the loan’s observable market value. The amount of recorded investment (unpaid principal net of any interest payments made by the borrower during the nonaccrual period and net of any partial charge-offs, accrued interest and deferred fees and costs) in an impaired loan that exceeds the fair value is accrued as estimated loss in the allowance. Impaired loans for which collection of interest or principal is in doubt are placed in nonaccrual status.

General allowances are established for collectively-evaluated loans. Collectively-evaluated loans are grouped into classes based on similar characteristics. Factors considered in determining general allowances include net charge-off trends, internal risk ratings, delinquency and nonperforming rates, product mix, underwriting practices, industry trends and economic trends.

The Company’s charge-off policy meets or is more stringent than the minimum standards required by regulators. When available information confirms that a specific loan or a portion thereof, within any loan class, is uncollectible the amount is charged off against the allowance for loan losses. Additionally, losses on consumer real estate and consumer non-real estate loans are typically charged off no later than when the loans are 120-180 days past due, and losses on loans secured by residential real estate or by commercial real estate are charged off by the time the loans reach 180 days past due, in compliance with regulatory guidelines. Accordingly, secured loans may be charged down to the estimated value of the collateral, with previously accrued unpaid interest reversed. Subsequent charge-offs may be required as a result of changes in the market value of collateral or other repayment prospects.

Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]

Troubled Debt Restructurings (“TDRs”)

In situations where, for economic or legal reasons related to a borrower’s financial condition, management grants a concession to the borrower that it would not otherwise consider, the related loan is classified as a troubled debt restructuring (TDR). These modified terms may include reduction of the interest rate, extension of the maturity date at an interest rate lower than the current market rate for a new loan with similar risk, forgiveness of principal or accrued interest or other actions intended to minimize the economic loss. TDR loans are individually measured for impairment.

Rate Lock Commitments [Policy Text Block]

Rate Lock Commitments

The Company enters into commitments to originate mortgage loans in which the interest rate on the loan is determined prior to funding (rate lock commitments). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. The period of time between issuance of a loan commitment and closing and sale of the loan generally ranges from 30 to 60 days. The Company protects itself from changes in interest rates through the use of best efforts forward delivery commitments, by committing to sell a loan at the time the borrower commits to an interest rate with the intent that the buyer has assumed interest rate risk on the loan. As a result, the Company is not exposed to losses nor will it realize significant gains related to its rate lock commitments due to changes in interest rates. The correlation between the rate lock commitments and the best efforts contracts is very high due to their similarity.

The market value of rate lock commitments and best efforts contracts is not readily ascertainable with precision because rate lock commitments and best effort contracts are not actively traded in stand-alone markets. The Company determines the fair value of rate lock commitments and best efforts contracts by measuring the changes in the value of the underlying assets while taking into consideration the probability that the rate lock commitments will close. Because of the high correlation between rate lock commitments and best efforts contracts, no gain or loss occurs on the rate lock commitments.

Property, Plant and Equipment, Policy [Policy Text Block]

Premises and Equipment

Land is carried at cost. Premises and equipment are stated at cost, net of accumulated depreciation. Depreciation is charged to expense over the estimated useful lives of the assets on the straight-line basis. Depreciable lives include 40 years for premises, 3-10 years for furniture and equipment, and 3 years for computer software. Costs of maintenance and repairs are charged to expense as incurred and improvements are capitalized.

Loans and Leases Receivable, Real Estate Acquired Through Foreclosure, Policy [Policy Text Block]

Other Real Estate Owned

Real estate acquired through or in lieu of foreclosure is held for sale and is initially recorded at fair value less estimated costs to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less estimated costs to sell. Revenue and expenses from operations and changes in the valuation allowance are included in other operating expenses.

Goodwill and Intangible Assets, Policy [Policy Text Block]

Intangible Assets and Goodwill

The Company records as goodwill the excess of purchase price over the fair value of the identifiable net assets acquired. Goodwill is subject to at least an annual assessment for impairment by applying a fair value based test. The Company performs its annual analysis as of September 30 of each fiscal year. Accounting guidance permits preliminary assessment of qualitative factors to determine whether more substantial impairment testing is required. The Company chose to bypass the preliminary assessment and utilized a two-step process for impairment testing of goodwill. The first step tests for impairment, while the second step, if necessary, measures the impairment.

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 NBI, while the third technique uses current market pricing multiples for change-of-control transactions involving companies comparable to NBI. 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.

Each measure indicated that the Company’s fair value exceeded its book value. No indicators of impairment for goodwill were identified during the years ended December 31, 2015, 2014, and 2013.

Acquired intangible assets (such as core deposit intangibles) are recognized separately from goodwill if the benefit of the asset can be sold, transferred, licensed, rented, or exchanged, and amortized over its useful life. The Company amortizes on a straight-line basis intangible assets arising from branch purchase transactions over their useful lives, generally ten to twelve years. Core deposit intangibles are subject to a recoverability test based on undiscounted cash flows, and to the impairment recognition and measurement provisions required for other long-lived assets held and used. The impairment testing showed that the expected cash flows of the intangible assets exceeded the carrying value.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Stock-Based Compensation

The Company’s 1999 Stock Option Plan terminated on March 9, 2009. Incentive stock options, all of which are now vested, were granted in the early years of the Plan. The Company recognized the cost of employment services received in exchange for awards of equity instruments based on the fair value of those awards on the date of grant. Compensation cost was recognized over the award’s required service period, which was the vesting period.

Pension and Other Postretirement Plans, Pensions, Policy [Policy Text Block]

Pension Plan

The Company recognizes the overfunded or underfunded status of a defined benefit postretirement plan as an asset or liability in its statement of financial position and recognizes changes in that funded status in the year in which the changes occur through comprehensive income. The funded status of a benefit plan is measured as the difference between plan assets at fair value and the projected benefit obligation.

Income Tax, Policy [Policy Text Block]

Income Taxes

Income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur.

Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.

The Company recognizes interest and penalties on income taxes as a component of income tax expense.

Trust Assets and Income [Policy Text Block]

Trust Assets and Income

Assets (other than cash deposits) held by the Trust Department in a fiduciary or agency capacity for customers are not included in the consolidated financial statements since such items are not assets of the Company. Trust income is recognized on the accrual basis.

Earnings Per Share, Policy [Policy Text Block]

Earnings Per Common Share

Basic earnings per common share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate solely to stock options outstanding during the period and are determined using the treasury stock method.

The following shows the weighted average number of shares used in computing earnings per common share and the effect on the weighted average number of shares of dilutive potential common stock.

	2015		2014		2013
Average number of common shares outstanding		6,953,849		6,948,789		6,947,974
Effect of dilutive options		3,245		10,345		20,419
Average number of common shares outstanding used to calculate diluted earnings per common share		6,957,094		6,959,134		6,968,393

The computation of diluted net income per common share excludes shares for stock options that would be anti-dilutive. There were no anti-dilutive shares in 2015, 2014 or 2013.

Commitments and Contingencies, Policy [Policy Text Block]

Loss Contingencies

Loss contingencies, including claims and legal actions arising in the ordinary course of business are recorded as liabilities when the likelihood of loss is probable and reasonably estimated. Management does not believe there are such matters that will have a material effect on the financial statements.

Advertising Costs, Policy [Policy Text Block]

Advertising

The Company charges advertising costs to expenses as incurred. In 2015, the Company expensed $105, and expensed $174 and $194 in 2014 and 2013, respectively.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

In preparing consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of foreclosed real estate, other-than-temporary impairments of securities, evaluation of impairment of goodwill and other intangibles, and pension obligations.

Changing economic conditions, adverse economic prospects for borrowers, as well as regulatory agency action as a result of examination, could cause NBB to recognize additions to the allowance for loan losses and may also affect the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans.

Certain reclassifications have been made to prior period balances to conform to the current year provisions.

New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting Pronouncements

In June 2014, the FASB issued ASU No. 2014-12, “Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” The new guidance applies to reporting entities that grant employees share-based payments in which the terms of the award allow a performance target to be achieved after the requisite service period. The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. Existing guidance in “Compensation – Stock Compensation (Topic 718),” should be applied to account for these types of awards. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted and reporting entities may choose to apply the amendments in the ASU either on a prospective or retrospective basis. The Company does not expect the adoption of ASU 2014-12 to have a material impact on its consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” This update is intended to provide guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management is required under the new guidance to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued when preparing financial statements for each interim and annual reporting period. If conditions or events are identified, the ASU specifies the process that must be followed by management and also clarifies the timing and content of going concern footnote disclosures in order to reduce diversity in practice. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-15 to have a material impact on its consolidated financial statements.

In November 2014, the FASB issued ASU No. 2014-16, “Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity.” The amendments in ASU do not change the current criteria in U.S. GAAP for determining when separation of certain embedded derivative features in a hybrid financial instrument is required. The amendments clarify how current U.S. GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of the host contract. Furthermore, the amendments clarify that no single term or feature would necessarily determine the economic characteristics and risks of the host contract. Rather, the nature of the host contract depends upon the economic characteristics and risks of the entire hybrid financial instrument. The amendments in this ASU also clarify that, in evaluating the nature of a host contract, an entity should assess the substance of the relevant terms and features (i.e., the relative strength of the debt-like or equity-like terms and features given the facts and circumstances) when considering how to weight those terms and features. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption, including adoption in an interim period, is permitted. The Company does not expect the adoption of ASU 2014-16 to have a material impact on its consolidated financial statements.

In January 2015, the FASB issued ASU No. 2015-01, “Income Statement—Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” The amendments in this ASU eliminate from U.S. GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. If an event or transaction meets the criteria for extraordinary classification, an entity is required to segregate the extraordinary item from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. The entity also is required to disclose applicable income taxes and either present or disclose earnings-per-share data applicable to the extraordinary item. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect the adoption of ASU 2015-01 to have a material impact on its consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” The amendments in this ASU are intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). In addition to reducing the number of consolidation models from four to two, the new standard simplifies the FASB Accounting Standards Codification™ and improves current GAAP by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE), and changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. ASU 2015-02 may be applied retrospectively in previously issued financial statements for one or more years with a cumulative-effect adjustment to retained earnings as of the beginning of the first year restated. The Company does not expect the adoption of ASU 2015-02 to have a material impact on its consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, “Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The amendments in this ASU are intended to simplify the presentation of debt issuance costs. These amendments require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. The amendments in this ASU are effective for public business entities for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. The Company does not expect the adoption of ASU 2015-03 to have a material impact on its consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” The amendments in this ASU provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments do not change the accounting for a customer’s accounting for service contracts. As a result of the amendments, all software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. The amendments in this ASU are effective for public business entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. An entity can elect to adopt the amendments either: (1) prospectively to all arrangements entered into or materially modified after the effective date; or (2) retrospectively. The Company does not expect the adoption of ASU 2015-05 to have a material impact on its consolidated financial statements.

In May 2015, the FASB issued ASU No. 2015-08, “Business Combinations (Topic 805): Pushdown Accounting – Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115.” The amendments in ASU 2015-08 amend various SEC paragraphs pursuant to the issuance of Staff Accounting Bulletin No. 115, Topic 5: Miscellaneous Accounting, regarding various pushdown accounting issues, and did not have a material impact on our consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-12, “Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), and Health and Welfare Benefit Plans (Topic 965) – 1. Fully Benefit-Responsive Investment Contracts, 2. Plan Investment Disclosures, and 3. Measurement Date Practical Expedient.” The amendments within this ASU are in 3 parts. Among other things, Part 1 amendments designate contract value as the only required measure for fully benefit-responsive investment contracts; Part II amendments eliminate the requirement that plans disclose: (a) individual investments that represent 5 percent or more of net assets available for benefits; and (b) the net appreciation or depreciation for investments by general type requirements for both participant-directed investments and nonparticipant-directed investments. Part III amendments provide a practical expedient to permit plans to measure investments and investment-related accounts (e.g., a liability for a pending trade with a broker) as of a month-end date that is closest to the plan’s fiscal year-end, when the fiscal period does not coincide with month-end. The amendments in Parts 1 and 2 of this ASU are effective on a retrospective basis and Part 3 is effective on a prospective basis, for fiscal years beginning after December 15, 2015. Early adoption is permitted. The Company does not expect the adoption of ASU 2015-12 to have a material impact on its consolidated financial statements.

In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date.” The amendments in ASU 2015-14 defer the effective date of ASU 2014-09 for all entities by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. All other entities may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities also may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, and interim reporting periods within annual reporting periods beginning one year after the annual reporting period in which the entity first applies the guidance in ASU 2014-09. The Company does not expect the adoption of ASU 2015-14 (or ASU 2014-09) to have a material impact on its consolidated financial statements.

In August 2015, the FASB issued ASU 2015-15, “Interest – Imputation of Interest (Subtopic 835-30) – Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements (Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting).” On April 7, 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires entities to present debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability. The guidance in ASU 2015-03 (see paragraph 835-30-45-1A) does not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff stated that they would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-15 adds these SEC comments to the "S" section of the Codification. The adoption of ASU 2015-15 did not have a material impact on our consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments.” The amendments in ASU 2015-16 require that an acquirer recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed at the acquisition date. The amendments also require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the estimated amounts had been recognized as of the acquisition date. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. The amendments should be applied prospectively to adjustments to provisional amounts that occur after the effective date with earlier application permitted for financial statements that have not been issued. The Company does not expect the adoption of ASU 2015-16 to have a material impact on its consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in ASU 2016-01, among other things: 1) Requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. 2) Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 3) Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). 4) Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently assessing the impact that ASU 2016-01 will have on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-01, “Leases (Topic 842).” Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) A lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU 2016-02 will have on its consolidated financial statements.
