PART I

ITEM 1. BUSINESS

General

County Bancorp, Inc. (“we,” “us,” “our” or the “Company”) is a Wisconsin corporation founded in May 1996 and is registered as a bank holding company under the Bank Holding Company Act of 1956, as amended (the “BHCA”). Our primary activities consist of holding the stock of our wholly-owned subsidiary bank, Investors Community Bank (the “Bank”), and providing a wide range of banking and related business activities through the Bank and our other subsidiaries. At December 31, 2017, we had total assets of approximately $1.4 billion. For additional financial information, see our consolidated financial statements in Part II, Item 8 of this Form 10-K.

Investors Community Bank

Investors Community Bank is a Wisconsin state bank originally chartered in 1997, and headquartered in Manitowoc, Wisconsin. The Bank is an independent community bank offering a full range of financial services focusing on the needs of agricultural businesses statewide, with a primary focus on dairy-related lending with lending relationships in 60 of Wisconsin’s 72 counties.  We also serve business customers throughout Wisconsin but primarily are focused in northeastern and central Wisconsin.  Our customers are served from our full-service branches in Manitowoc, Appleton, Green Bay, and Stevens Point, and our loan production offices in Darlington, Eau Claire, Fond du Lac, and Sheboygan.

Subsidiaries

In addition to the Bank, we have three wholly-owned subsidiaries, County Bancorp Statutory Trust II, County Bancorp Statutory Trust III, and Fox River Valley Trust I, which are Delaware statutory trusts which were formed for the purpose of issuing trust preferred securities.  The Bank is the sole member of Investor Insurance Services, LLC, which provides crop insurance and milk margin products to the agricultural sector of Wisconsin, and ABS 1, LLC, which holds real estate and personal property for sale that was obtained through repossession, both of which are Wisconsin limited liability companies.  During 2017, the Bank dissolved the ICB Investment Corp. and distributed its assets to the Bank.

Merger Transaction

On May 13, 2016, we completed a merger with Fox River Valley Bancorp, Inc. (“Fox River Valley”), a Wisconsin corporation, pursuant to which the Company acquired Fox River Valley.  In connection with and immediately following the merger, The Business Bank, a Wisconsin-chartered bank and wholly-owned subsidiary of Fox River Valley, merged with and into the Bank.  For additional information on this merger, see Note 2. “Acquisition” to our consolidated financial statements in Part II, Item 8 of this Form 10-K.

Corporate Governance Matters

We maintain a website at www.investorscommunitybank.com. We make available through the Investor Relations link on that website, free of charge, copies of our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and amendments to those reports, as soon as reasonably practicable after we electronically file those materials with, or furnish them to, the Securities and Exchange Commission (“SEC”).  Investors can read and copy any materials we file with the SEC at the SEC’s Public Reference Room at 100 F Street, NE, Washington, DC 20549, on official business days during the hours of 10:00 am to 3:00 pm.  Investors can obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330.  The SEC also maintains a website at www.sec.gov that contains reports, proxy statements and other information regarding SEC registrants.

Market

Our agricultural banking business, which is primarily dairy-related, extends throughout Wisconsin.  We had lending relationships in60 of the state’s 72 counties as of December 31, 2017. We also serve business customers throughout Wisconsin with a focus on northeastern and central Wisconsin.

The economy in Wisconsin represents a diverse range of industries, including manufacturing, trade, agriculture, professional and business services, finance and insurance, and government industries.  According to the Bureau of Economic Analysis, the broader Wisconsin economy is growing at a pace on par with that of the United States as a whole, and the overall unemployment rate was a fifteen-year low and below the national rate of unemployment for all of 2017.

3

Dairy-related business lending has proven to be a source of stability and steady growth for both the Bank and the state of Wisconsin. The economic impact of the dairy industry on Wisconsin is significant. According to a 2012 report from the University of Wisconsin-Madison, as part of the overall Wisconsin agricultural economy, the dairy sector contributed $43.4 billion of revenue to the state’s economy. According to a 2015 report from the University of Wisconsin-Madison, total revenue for the agricultural industry in Wisconsin was just over $59 billion in 2007 and had grown to $88.3 billion in 2012, representing approximately a 49% increase.  According to the United States Department of Agriculture (“USDA”), Wisconsin milk production topped 30 billion pounds for the first time in 2016, a 28.7% increase since 2006, and leads the nation in cheese production with more than three billion pounds produced.

According to the Wisconsin Milk Marketing Board, since 1990, the average consumption of cheese has increased 43%, and the average consumption of yogurt increased 277%.   According to the USDA, in 2016, Wisconsin was the home of 23% of all U.S. dairy farms. We believe the available customer base, the increasing demand for agricultural products and changing agricultural industry dynamics will continue to drive the need for agricultural banking services. Furthermore, the broader business banking environment in Wisconsin continues to grow. We believe the Bank is well positioned to continue serving the banking needs of agricultural and business banking customers throughout Wisconsin.

Our Products and Services

The Bank provides a wide range of consumer and commercial banking services to individuals, businesses, and industries. The basic services offered by the Bank include: demand interest bearing and noninterest bearing accounts, money market deposit accounts, NOW accounts, time deposits, mobile banking, internet banking, remote merchant deposit capture, cash management services, safe deposit services, credit cards, debit cards, direct deposits, notary services, night depository, cashier’s checks, drive-in tellers, banking by mail, and certain consumer loans, both collateralized and uncollateralized. In addition, the Bank makes secured and unsecured commercial loans as well as loans secured by residential and commercial real estate, and issues stand-by letters of credit. The Bank provides access to ATM cards and is a member of the Pulse and Cirrus ATM networks thereby enabling customers to utilize the convenience of ATM access nationwide and internationally.

The revenues of the Bank are primarily derived from interest on loans and fees received in connection with loans, interest and dividends on its investment securities, and non-interest income primarily generated from loan sales and loan servicing rights. The principal sources of funds for the Bank’s lending activities are deposits (primarily consumer deposits and brokered deposits), loan repayments, and income on and proceeds from the sale of investment securities. The Bank’s principal expenses are interest paid on deposits and operating and general administrative expenses. The Bank also generates non-interest income from Investors Insurance Services, LLC, which is a wholly-owned subsidiary of the Bank. Investors Insurance Services, LLC, provides crop insurance and milk margin products to the agricultural sector of Wisconsin.

As is the case with financial institutions generally, our operations are materially and significantly influenced by general economic conditions and by related monetary and fiscal policies of financial institution regulatory agencies, including the Board of Governors of the Federal Reserve System (the “Federal Reserve”), the Federal Deposit Insurance Corporation (“FDIC”) and the Wisconsin Department of Financial Institutions (“WDFI”) Banking Division. Deposit flows and costs of funds are influenced by interest rates on competing investments and general market interest rates. Lending activities are affected by the demand for financing of real estate and other types of loans, which in turn is affected by the interest rates at which such financing may be offered and other factors affecting local demand and availability of funds. The Bank faces strong competition in the attraction of deposits and the origination of loans. For additional information about the competition we face, see the section of this Form 10-K entitled “Item I - Business—Competition.”

Lending Activities

Loans

A significant source of our revenues is the interest earned on the Bank’s loan portfolio.  At December 31, 2017, our total assets were $1.4 billion and our total loans were $1.1 billion, or 82.2% of total assets.  At December 31, 2016, our total assets were $1.2 billion and our total loans were $1.0 billion, or 82.9% of total assets. At December 31, 2015, our total assets were $884.9 million and our total loans were $748.2 million, or 84.6% of total assets.  At December 31, 2014, our total assets were $771.8 million and our total loans were $648.1 million, or 84.0% of total assets.  The increase in total loans from December 31, 2016 to December 31, 2017 was $118.5 million (11.5%).  The increase in total loans from December 31, 2015 to December 31, 2016, was $282.3 million (37.7%) primarily due to the merger with Fox River Valley, and from December 31, 2014 to December 31, 2015, total loans increased $100.1 million (15.4%). For the periods indicated below, the net change in total loans (excluding the allowance for loan losses) was as follows:

Loan Portfolio Concentrations

Although our loan portfolio is concentrated in agricultural loans, which is heavily dependent on the dairy industry, there are a number of mitigating factors to this concentration risk. First, our farm customers are diversified geographically throughout the state of Wisconsin, which we believe helps mitigate the weather-related risk impacting feed availability and cost. Secondly, the USDA provides government support for a number of insurance-type products that dairy producers can purchase, which we believe substantially mitigate weather and pricing risks for crops and pricing risks for milk. The availability of these types of products in

5

addition to the ability to use the futures markets to hedge both milk price and feed cost brings some additional stability and predictability to the cash flows of farmers.

We originate and maintain large credit relationships with a number of customers in the ordinary course of our business. We have established a formal, internal lending limit on loans to one borrower of $8 million, which is significantly lower than our legal lending limit of approximately $28 million as of December 31, 2017. Exceptions to this internal limit may be made in the case of particularly strong credits. As of December 31, 2017, 20 relationships exceeded our internal lending limit with total combined credit risk exposure of $203.2 million, or 123% of total risk-based capital, and only nine of these relationships exceeded $10 million, with the largest being $15.3 million.

Loan Underwriting

Management seeks to maintain a high quality of loans through sound underwriting and lending practices. We believe an important measurement for monitoring overall credit quality of our loan portfolio is the ratio of non-performing assets to total assets as nonperforming loans may ultimately progress to other real estate owned (“OREO”). Accordingly, the initial underwriting of loans is vital. Our ratios of non-performing assets to total assets as of December 31, 2017, December 31, 2016, December 31, 2015, and 2014 were 1.15%, 1.84%, 3.10%, and 2.42%, respectively. We have customized our loan underwriting to reflect the risks that are specific to each product type as described below.

Agricultural Lending. Our agricultural banking team consists of bankers, who all grew up on farms in Wisconsin, which provides a solid understanding of the nuances of the industry. As of the date of this filing, we have eleven agricultural banking officers driving the relationships with our customers, as well as five crop insurance sales representatives. Our philosophy is to bring the Bank to the customer, and most contacts are made on the farm. We believe the deep relationships our team has with our agricultural customers, and the value each team member provides given his or her strong agricultural roots, creates a barrier to entry for our competitors. We believe this regular personal contact with our customers provides a high level of service and allows our bankers to monitor our credits more effectively.

Our relationships with our agricultural customers typically involve their entire primary banking needs. We lend money to our customers for short-term needs, such as planting crops or buying feed. We also provide intermediate-term loans to fund cattle or equipment needs, as well as longer-term real estate loans to provide funds to purchase real estate or improve existing real estate. Collateral for these loans will typically involve cross-collateralization of all of a farm’s assets, and the Bank will be in a primary lien position. We apply a consistent credit philosophy when underwriting agricultural loans, which focuses on repayment of credit facilities from current and historical cash flow analysis, both cash and accrual. Other factors considered in granting credit are management capability, collateral quality and adequacy, and balance sheet leverage.

Commercial Lending. Our commercial and industrial loans (“commercial loans”) are offered by business bankers who, as a group, have extensive experience in making commercial loans. Our commercial loan portfolio is comprised of conventional term loans, lines of credit and government guaranteed loans, primarily Small Business Administration (“SBA”) loans. These loans have either adjustable or fixed rates typically with terms of five years or less, although terms are generally longer with SBA guarantees. Commercial loans are underwritten on the basis of the borrower’s ability to make repayment for the cash flow of its business and generally are collateralized by business assets, such as accounts receivable, equipment and inventory, as well as personal guarantees of the principals. The availability of funds for the repayment of commercial loans is substantially dependent on the success of the business itself, which is subject to adverse economic conditions.

Commercial Real Estate Lending.  Commercial real estate mortgage loans (“CRE loans”) in our portfolio consist of fixed and adjustable interest rate loans that were originated at prevailing market interest rates. Our policy has been to originate CRE loans predominantly in our primary market area. CRE loans consist primarily of multi-family investment properties and investment retail, office, mini-storage and warehouse loans. These loans are generally underwritten to a maximum loan-to-value ratio of 75% of the lower of appraised value or purchase price of the property securing the loan. In making CRE loans, we primarily consider the net operating income generated by the real estate to support the debt service, the financial resources, income level and managerial expertise of the borrower, the marketability of the collateral and our lending experience with the borrower. CRE loans entail significant additional risks compared to residential mortgage loans. The collateral underlying CRE loans may depreciate over time, cannot be appraised with as much precision as residential real estate, and may fluctuate in value based on the success of the tenants.

Consumer Lending. At this time, we do not originate consumer, personal, and residential real estate loans, however, we do continue to service legacy loans. These loans are most often collateralized by primary residences, secondary residences, automobiles and recreational vehicles. Consumer loans are priced at prevailing market rates and are made to the individuals responsible for making the scheduled payments. Consumer and personal loans generally have a term of five years or less, with amortizations that match the

6

useful life of the assets being financed. Consumer loans represented less than 0.1% of our overall loan portfolio as of December 31, 2017.

Concentrations. Loan concentrations are defined as amounts loaned to multiple borrowers engaged in similar activities that could cause them to be similarly impacted by economic or other conditions. We, on a routine basis, monitor these concentrations in order to consider adjustments in our lending practices to reflect economic conditions, loan to deposit ratios, and industry trends. As of December 31, 2017, 2016, 2015, and 2014, there is a concentration of agricultural real estate and agricultural production loans, which together comprised approximately 59.7%, 60.6%, 66.8%, and 64.1% of our loan portfolio on such dates, respectively.  There was also a concentration of commercial real estate loans at December 31, 2017 and 2016, which comprised approximately 25.5% and 26.3%, respectively, of our loan portfolio on such dates.  Other than as previously described, there were no concentrations of loans within any portfolio category to any group of borrowers engaged in similar activities or in a similar business that exceeded 25% of total loans at December 31, 2017, 2016, 2015, or 2014.

The credit committee of the board of directors of the Bank concentrates its efforts and resources, and that of its senior management and lending officers, on loan review and underwriting procedures. Internal controls include ongoing reviews of loans made to monitor documentation and the existence and valuations of collateral. In addition, management of the Bank has established a review process with the objective of identifying, evaluating, and initiating necessary corrective action for troubled and stressed loans. The goal of the loan review process is to address classified and non-performing loans as early as possible.

For additional information concerning our risk management, see “Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations—Risk Management.”

Loan Servicing

As part of our growth and risk management strategy, we have actively developed a loan participation and loan sales network. Our ability to sell loan participations and whole loans benefits us by freeing up capital and funding to lend to new customers, but because we continue to service these loans, we are able to maintain a relationship with the customer. Additionally, we typically earn a gain on the sale of loans sold and receive a servicing fee that generally exceeds the cost of administering the loan and maintaining the customer relationship.

The following table shows the total portfolio of loans and loans serviced as of the dates indicated below:

	As of  December 31,
	2017			2016			2015			2014

Total loans and loans serviced	$	1,748,359		$	1,605,487		$	1,240,177		$	1,068,521

Classification of Assets

Interest on loans accrues and is credited to income based upon the principal balance outstanding. It is management’s policy to discontinue the accrual of interest income and classify a loan as nonaccrual when principal or interest is past due 90 days or more unless, in the opinion of management, the credit is well secured and in the process of collection. Loans may also be placed on nonaccrual status when, in management’s opinion, repayment is not likely to be paid in accordance with the terms of the obligation. Consumer installment loans are generally charged-off after 90 days of delinquency unless adequately collateralized and in the process of collection. Loans are not returned to accrual status until principal and interest payments are brought current and future payments appear reasonably certain. Interest accrued and unpaid at the time a loan is placed on nonaccrual status is charged against interest income.

Real estate acquired by us as a result of foreclosure or by deed in lieu of foreclosure is classified as OREO. OREO properties are recorded on the balance sheet at the lower of cost or fair value less estimated selling costs, and the estimated loss, if any, is charged to the allowance for loan losses at the time it is transferred to OREO. Further write-downs in OREO are recorded at the time management believes additional deterioration in value has occurred and are charged to non-interest expense. Our OREO, of which, at

7

December 31,2017, $4.6 million was considered non-performing assets and $0.4 million was related to Bank property transferred from premises and equipment so it could be held for sale, increased during 2017 despite selling much of the previously recorded OREO, as we experienced an agricultural default of one property in 2017.  At December 31, 2017, December 31, 2016, December 31, 2015, and December 31, 2014, we had OREO of $5.0 million, $3.2 million, $2.9 million, and $7.1 million, respectively.

At December 31, 2017, loans 30 to 89 days delinquent consisted of three customer relationships, which totaled $1.5 million. Management continually evaluates the collectability of its non-performing loans and the adequacy of its allowance for loan losses to absorb the identified and unidentified losses inherent in the loan portfolio. As a result of these evaluations, loans considered uncollectible are charged-off, and adjustments to the reserve considered necessary are provided through a provision charged against earnings. These evaluations consider the current economic environment, the real estate market and its impact on underlying collateral values, trends in the level of non-performing and past-due loans, and changes in the size and composition of the loan portfolio.

Provision for loan losses for the years ended December 31, 2017, 2016, 2015, and 2014 totaled $2.3 million, $3.0 million, $(1.0) million, and $589 thousand, respectively. For the years ended December 31, 2017, 2016, and 2014, net loans charged off totaled $1.7 million, $719 thousand, and $481 thousand, respectively.  For the year ended December 31, 2015, net loans of $821 thousand were recovered.  At December 31, 2017, 2016, 2015, and 2014, we had non-performing loans (i.e., nonaccrual loans and loans 90 days or more past due) of $11.6 million, $20.1 million, $24.6 million, and $11.6 million, respectively. Considering the nature of our loan portfolio, management believed that the allowance for loan losses at December 31, 2017 was adequate.

The activity in our allowance for loan losses was as follows as of the date indicated below:

Deposit Activities

Deposits are the major source of our funds for lending and other investment purposes. Deposits are attracted principally from within our primary market area through the offering of a broad variety of deposit instruments including checking accounts, money

market accounts, savings accounts, term certificate accounts (including “jumbo” certificates in denominations of $100,000 or more), and retirement savings plans. As of December 31, 2017, 2016, 2015, and 2014, the distribution by type of deposit accounts was as follows:

Our deposits during 2017 increased $132.6 million, or 13.6%, to $1.1 billion at December 31, 2017 from 2016, primarily as a result of increases in time and brokered deposits.  Our deposits increased $305.3 million, or 45.4%, from $672.2 million at December 31, 2015 to $977.5 million at December 31, 2016, which was primarily the result of our merger with Fox River Valley.  Our deposits increased during 2015, from $605.5 million at December 31, 2014 to $672.2 million at December 31, 2015, an increase of $66.8 million or 11.0%.

Maturity terms, service fees and withdrawal penalties are established by us on a periodic basis. The determination of rates and terms is predicated on funds acquisition and liquidity requirements, rates paid by competitors, growth goals and federal regulations.

Brokered and Other Deposits

We use various funding sources including: (i) core deposits consisting of traditional bank deposit products, such as demand deposits, money market accounts and certificates of deposit, and (ii) wholesale funds consisting of brokered deposits, national certificates of deposit and Federal Home Loan Bank of Chicago (the “FHLB”) advances. Wholesale funding is used to supplement normal deposit accumulation by us and to assist in asset liability management. We use brokered deposits to obtain non-putable deposits (except for death and incompetence) with maturities and options that assist in the management of various balance sheet interest rate risks. These deposits may have a higher or lower interest rate than deposits obtained locally.  Brokered deposit balances were $282.6 million, $193.6 million, $164.6 million, and $125.4 million at December 31, 2017, 2016, 2015, and 2014, respectively.

FDIC regulations limit the ability of certain insured depository institutions under certain conditions to accept, renew, or roll over brokered deposits at rates of interest which are significantly higher than the prevailing rates of interest on deposits offered by other insured depository institutions having the same type of charter in such depository institutions’ normal market area. Under these regulations, “well capitalized” depository institutions may accept, renew, or roll over deposits at such rates without restriction, “adequately capitalized” depository institutions may accept, renew or roll over deposits at such rates with a waiver from the FDIC (subject to certain restrictions on payments of rates), and “undercapitalized” depository institutions may not accept, renew or roll over deposits at such rates. The definitions of “well capitalized,” “adequately capitalized” and “undercapitalized” are the same as the definitions adopted by the agencies to implement the prompt corrective action provisions of applicable law.  As of December 31, 2017, 2016, 2015, and 2014, the Bank met the definition of a “well capitalized” depository institution.

Time deposits of $100,000 and over, public fund deposits and other large deposit accounts tend to be short-term in nature and more sensitive to changes in interest rates than other types of deposits and, therefore, may be a less stable source of funds. In the event that existing short-term deposits are not renewed, the resulting loss of the deposited funds could adversely affect our liquidity. In a rising interest rate market, such short-term deposits may prove to be a costly source of funds because their short-term nature facilitates renewal at increasingly higher interest rates, which may adversely affect our earnings. However, the converse is true in a falling interest-rate market where such short-term deposits are more favorable to us.

Competition

We encounter strong competition both in making loans and in attracting deposits. The deregulation of the banking industry and the widespread enactment of state laws that permit multi-bank holding companies as well as an increasing level of interstate banking have created a highly competitive environment for commercial banking. In one or more aspects of our business, we compete with other commercial banks, savings and loan associations, credit unions, finance companies, mutual funds, insurance companies, brokerage and investment banking companies and other financial intermediaries. Most of these competitors, some of which are affiliated with bank holding companies, have substantially greater resources and lending limits, and may offer certain services that we do not currently provide.

In addition, many of our non-bank competitors are not subject to the same extensive federal regulations that govern bank holding companies and federally insured banks. Recent federal and state legislation has heightened the competitive environment in which financial institutions must conduct their business, and the potential for competition among financial institutions of all types has increased significantly. There is no assurance that increased competition from other financial institutions will not have an adverse effect on our operations.

To compete, we rely upon specialized services, responsive handling of customer needs, and personal contacts by our officers, directors, and staff. Large multi-branch banking competitors tend to compete primarily by rate and the number and locations of branches while smaller, independent financial institutions tend to compete primarily by rate and personal service.  Based on data from the FDIC, as of June 30, 2017, the Bank held 38.2% of deposits in Manitowoc County, 9.3% in Portage County, 2.9% in Outagamie County, and 0.56% in Brown County.

Employees

At March 1, 2018, we had 136 full-time employees and 20 part-time employees.  Our employees are not represented by a collective bargaining unit.  We consider our relations with our employees to be excellent.

Supervision and Regulation

General

FDIC-insured institutions, their holding companies and their affiliates are extensively regulated under federal and state law.  As a result, the Company’s growth and earnings performance may be affected not only by management decisions and general economic conditions, but also by the requirements of federal and state statutes and by the regulations and policies of various bank regulatory agencies, including the WDFI, the Federal Reserve, the FDIC and the Consumer Financial Protection Bureau (“CFPB”).  Furthermore, taxation laws administered by the Internal Revenue Service and state taxing authorities, accounting rules developed by the Financial Accounting Standards Board (the “FASB”), securities laws administered by the SEC and state securities authorities, and anti-money laundering laws enforced by the U.S. Department of the Treasury (“Treasury”) have an impact on the Company’s business. The effect of these statutes, regulations, regulatory policies and accounting rules are significant to the Company’s operations and results.

Federal and state banking laws impose a comprehensive system of supervision, regulation and enforcement on the operations of FDIC-insured institutions, their holding companies and affiliates that is intended primarily for the protection of the FDIC-insured deposits and depositors of banks, rather than shareholders. These laws, and the regulations of the bank regulatory agencies issued under them, affect, among other things, the scope of the Company’s business, the kinds and amounts of investments we may make, reserve requirements, required capital levels relative to the Company’s assets, the nature and amount of collateral for loans, the establishment of branches, the Company’s ability to merge, consolidate and acquire, dealings with the Company’s insiders and affiliates and the Company’s payment of dividends. In reaction to the global financial crisis and particularly following the passage of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), we experienced heightened regulatory requirements and scrutiny. Although the reforms primarily targeted systemically important financial service providers, their

10

influence filtered down in varying degrees to community banks over time and caused the Company’s compliance and risk management processes, and the costs thereof, to increase. After the 2016 federal elections, momentum to decrease the regulatory burden on community banks gathered strength. Although these deregulatory trends continue to receive much discussion among the banking industry, lawmakers and the bank regulatory agencies, little substantive progress has yet been made. The true impact of proposed reforms remains difficult to predict with any certainty.

The supervisory framework for U.S. banking organizations subjects banks and bank holding companies to regular examination by their respective regulatory agencies, which results in examination reports and ratings that are not publicly available and that can impact the conduct and growth of their business. These examinations consider not only compliance with applicable laws and regulations, but also capital levels, asset quality and risk, management ability and performance, earnings, liquidity, and various other factors. The regulatory agencies generally have broad discretion to impose restrictions and limitations on the operations of a regulated entity where the agencies determine, among other things, that such operations are unsafe or unsound, fail to comply with applicable law or are otherwise inconsistent with laws and regulations or with the supervisory policies of these agencies.  

The following is a summary of the material elements of the supervisory and regulatory framework applicable to the Company and the Bank, beginning with a discussion of the continuing regulatory emphasis on the Company’s capital levels.  It does not describe all of the statutes, regulations and regulatory policies that apply, nor does it restate all of the requirements of those that are described. The descriptions are qualified in their entirety by reference to the particular statutory and regulatory provision.  

Regulatory Emphasis on Capital

Regulatory capital represents the net assets of a banking organization available to absorb losses. Because of the risks attendant to their business, FDIC-insured institutions are generally required to hold more capital than other businesses, which directly affects the Company’s earnings capabilities. While capital has historically been one of the key measures of the financial health of both bank holding companies and banks, its role became fundamentally more important in the wake of the global financial crisis, as the banking regulators recognized that the amount and quality of capital held by banks prior to the crisis was insufficient to absorb losses during periods of severe stress.  Certain provisions of the Dodd-Frank Act and Basel III, discussed below, establish strengthened capital standards for banks and bank holding companies, require more capital to be held in the form of common stock and disallow certain funds from being included in capital determinations. These standards represent regulatory capital requirements that are meaningfully more stringent than those in place previously.

Minimum Required Capital Levels.  Banks have been required to hold minimum levels of capital based on guidelines established by the bank regulatory agencies since 1983. The minimums have been expressed in terms of ratios of capital divided by total assets. As discussed below, bank capital measures have become more sophisticated over the years and have focused more on the quality of capital and the risk of assets. Bank holding companies have historically had to comply with less stringent capital standards than their bank subsidiaries and have been able to raise capital with hybrid instruments such as trust preferred securities. The Dodd-Frank Act mandated the Federal Reserve to establish minimum capital levels for holding companies on a consolidated basis as stringent as those required for FDIC-insured institutions. A result of this change is that the proceeds of hybrid instruments, such as trust preferred securities, are being excluded from capital over a phase-out period. However, if such securities were issued prior to May 19, 2010 by bank holding companies with less than $15 billion of assets, they may be retained, subject to certain restrictions. Because we have assets of less than $15 billion, we are able to maintain the Company’s trust preferred proceeds as capital but we have to comply with new capital mandates in other respects and will not be able to raise capital in the future through the issuance of trust preferred securities.

The Basel International Capital Accords. The risk-based capital guidelines for U.S. banks since 1989 were based upon the 1988 capital accord known as “Basel I” adopted by the international Basel Committee on Banking Supervision, a committee of central banks and bank supervisors that acts as the primary global standard-setter for prudential regulation, as implemented by the U.S. bank regulatory agencies on an interagency basis. The accord recognized that bank assets for the purpose of the capital ratio calculations needed to be risk-weighted (the theory being that riskier assets should require more capital) and that off-balance sheet exposures needed to be factored in the calculations. Basel I had a very simple formula for assigning risk weights to bank assets from 0% to 100% based on four categories.  In 2008, the banking agencies collaboratively began to phase-in capital standards based on a second capital accord, referred to as “Basel II,” for large or “core” international banks (generally defined for U.S. purposes as having total assets of $250 billion or more, or consolidated foreign exposures of $10 billion or more) known as “advanced approaches” banks. The primary focus of Basel II was on the calculation of risk weights based on complex models developed by each advanced approaches bank. As most banks were not subject to Basel II, the U.S. bank regulators worked to improve the risk sensitivity of Basel I standards without imposing the complexities of Basel II. This “standardized approach” increased the number of risk weight categories and recognized risks well above the original 100% risk-weighting. It is institutionalized by the Dodd-Frank Act for all banking organizations, even for the advanced approaches banks, as a floor.  

On September 12, 2010, the Group of Governors and Heads of Supervision, the oversight body of the Basel Committee on Banking Supervision, announced agreement on a strengthened set of capital requirements for banking organizations around the world, known as Basel III, to address deficiencies recognized in connection with the global financial crisis.   

11

The Basel III Rule. In July 2013, the U.S. federal banking agencies approved the implementation of the Basel III regulatory capital reforms in pertinent part, and, at the same time, promulgated rules effecting certain changes required by the Dodd-Frank Act (the “Basel III Rule”). In contrast to capital requirements historically, which were in the form of guidelines, Basel III was released in the form of regulations by each of the regulatory agencies. The Basel III Rule is applicable to all banking organizations that are subject to minimum capital requirements, including federal and state banks and savings and loan associations, as well as to bank and savings and loan holding companies, other than “small bank holding companies” (generally bank holding companies with consolidated assets of less than $1 billion).

The Basel III Rule required higher capital levels, increased the required quality of capital, and required more detailed categories of risk-weighting of riskier, more opaque assets. For nearly every class of assets, the Basel III Rule requires a more complex, detailed and calibrated assessment of credit risk and calculation of risk weightings.

Not only did the Basel III Rule increase most of the required minimum capital ratios in effect prior to January 1, 2015, but it introduced the concept of Common Equity Tier 1 Capital, which consists primarily of common stock, related surplus (net of Treasury stock), retained earnings, and Common Equity Tier 1 minority interests subject to certain regulatory adjustments. The Basel III Rule also changed the definition of capital by establishing more stringent criteria that instruments must meet to be considered Additional Tier 1 Capital (primarily non-cumulative perpetual preferred stock that meets certain requirements) and Tier 2 Capital (primarily other types of preferred stock and subordinated debt, subject to limitations).  A number of instruments that qualified as Tier 1 Capital under Basel I do not qualify, or their qualifications will change. For example, noncumulative perpetual preferred stock, which qualified as simple Tier 1 Capital under Basel I, does not qualify as Common Equity Tier 1 Capital, but qualifies as Additional Tier 1 Capital. The Basel III Rule also constrained the inclusion of minority interests, mortgage-servicing assets, and deferred tax assets in capital and requires deductions from Common Equity Tier 1 Capital in the event that such assets exceed a certain percentage of a banking institution’s Common Equity Tier 1 Capital.  

The Basel III Rule required minimum capital ratios as of January 1, 2015, as follows:

• A ratio of minimum Common Equity Tier 1 Capital equal to 4.5% of risk-weighted assets;

• An increase in the minimum required amount of Tier 1 Capital from 4% to 6% of risk-weighted assets;

• A continuation of the minimum required amount of Total Capital (Tier 1 plus Tier 2) at 8% of risk-weighted assets; and

• A minimum leverage ratio of Tier 1 Capital to total quarterly average assets equal to 4% in all circumstances.

In addition, institutions that seek the freedom to make capital distributions (including for dividends and repurchases of stock) and pay discretionary bonuses to executive officers without restriction must also maintain 2.5% in Common Equity Tier 1 Capital attributable to a capital conservation buffer being phased in over three years beginning in 2016 (as of January 1, 2018, it had phased in to 1.875%). The purpose of the conservation buffer is to ensure that banking institutions maintain a buffer of capital that can be used to absorb losses during periods of financial and economic stress. Factoring in the fully phased-in conservation buffer increases the minimum ratios depicted above to 7% for Common Equity Tier 1 Capital, 8.5% for Tier 1 Capital and 10.5% for Total Capital.  

Banking organizations (except for large, internationally active banking organizations) became subject to the new rules on January 1, 2015. However, there are separate phase-in/phase-out periods for: (i) the capital conservation buffer; (ii) regulatory capital adjustments and deductions; (iii) nonqualifying capital instruments; and (iv) changes to the prompt corrective action rules discussed below. The phase-in periods commenced on January 1, 2016 and extend until January 1, 2019.

Well-Capitalized Requirements.The ratios described above are minimum standards in order for banking organizations to be considered “adequately capitalized.” Bank regulatory agencies uniformly encourage banks to hold more capital and be “well-capitalized” and, to that end, federal law and regulations provide various incentives for banking organizations to maintain regulatory capital at levels in excess of minimum regulatory requirements. For example, a banking organization that is well-capitalized may: (i) qualify for exemptions from prior notice or application requirements otherwise applicable to certain types of activities; (ii) qualify for expedited processing of other required notices or applications; and (iii) accept, roll-over or renew brokered deposits. Higher capital levels could also be required if warranted by the particular circumstances or risk profiles of individual banking organizations. For example, the Federal Reserve’s capital guidelines contemplate that additional capital may be required to take adequate account of, among other things, interest rate risk, or the risks posed by concentrations of credit, nontraditional activities or securities trading activities. Further, any banking organization experiencing or anticipating significant growth would be expected to maintain capital ratios, including tangible capital positions (i.e., Tier 1 Capital less all intangible assets), well above the minimum levels.

Under the capital regulations of the FDIC and Federal Reserve, in order to be well‑capitalized, a banking organization must maintain:

• A Common Equity Tier 1 Capital ratio to risk-weighted assets of 6.5% or more;

• A ratio of Tier 1 Capital to total risk-weighted assets of  8% or more (6% under Basel I);

12

• A ratio of Total Capital to total risk-weighted assets of 10% or more (the same as Basel I); and

• A leverage ratio of Tier 1 Capital to total adjusted average quarterly assets of 5% or greater.

It is possible under the Basel III Rule to be well-capitalized while remaining out of compliance with the capital conservation buffer discussed above.

As of December 31, 2017: (i) the Bank was not subject to a directive from the FDIC to increase its capital and (ii) the Bank was well-capitalized, as defined by FDIC regulations.  As of December 31, 2017, the Company had regulatory capital in excess of the Federal Reserve’s requirements and met the Basel III Rule requirements to be well-capitalized.

Prompt Corrective Action.An FDIC-insured institution’s capital plays an important role in connection with regulatory enforcement as well.  Federal law provides the federal banking regulators with broad power to take prompt corrective action to resolve the problems of undercapitalized institutions.  The extent of the regulators’ powers depends on whether the institution in question is “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” or “critically undercapitalized,” in each case as defined by regulation.  Depending upon the capital category to which an institution is assigned, the regulators’ corrective powers include: (i) requiring the institution to submit a capital restoration plan; (ii) limiting the institution’s asset growth and restricting its activities; (iii) requiring the institution to issue additional capital stock (including additional voting stock) or to sell itself; (iv) restricting transactions between the institution and its affiliates; (v) restricting the interest rate that the institution may pay on deposits; (vi) ordering a new election of directors of the institution; (vii) requiring that senior executive officers or directors be dismissed; (viii) prohibiting the institution from accepting deposits from correspondent banks; (ix) requiring the institution to divest certain subsidiaries; (x) prohibiting the payment of principal or interest on subordinated debt; and (xi) ultimately, appointing a receiver for the institution.

Regulation and Supervision of the Company

General.  The Company, as the sole shareholder of the Bank, is a bank holding company. As a bank holding company, we are registered with, and subject to regulation by, the Federal Reserve under the BHCA. We are legally obligated to act as a source of financial and managerial strength to the Bank and to commit resources to support the Bank in circumstances where we might not otherwise do so. Under the BHCA, we are subject to periodic examination by the Federal Reserve and are required to file with the Federal Reserve periodic reports of the Company’s operations and such additional information regarding us and the Bank as the Federal Reserve may require.  

Acquisitions, Activities and Change in Control.The primary purpose of a bank holding company is to control and manage banks.The BHCA generally requires the prior approval of the Federal Reserve for any merger involving a bank holding company or any acquisition by a bank holding company of another bank or bank holding company. Subject to certain conditions (including deposit concentration limits established by the BHCA), the Federal Reserve may allow a bank holding company to acquire banks located in any state of the United States. In approving interstate acquisitions, the Federal Reserve is required to give effect to applicable state law limitations on the aggregate amount of deposits that may be held by the acquiring bank holding company and its FDIC-insured institution affiliates in the state in which the target bank is located (provided that those limits do not discriminate against out-of-state institutions or their holding companies) and state laws that require that the target bank have been in existence for a minimum period of time (not to exceed five years) before being acquired by an out-of-state bank holding company. Furthermore, in accordance with the Dodd-Frank Act, bank holding companies must be well-capitalized and well-managed in order to effect interstate mergers or acquisitions. For a discussion of the capital requirements, see “Regulatory Emphasis on Capital” above.

The BHCA generally prohibits the Company from acquiring direct or indirect ownership or control of more than 5% of the voting shares of any company that is not a bank and from engaging in any business other than that of banking, managing and controlling banks or furnishing services to banks and their subsidiaries. This general prohibition is subject to a number of exceptions. The principal exception allows bank holding companies to engage in, and to own shares of companies engaged in, certain businesses found by the Federal Reserve prior to November 11, 1999 to be “so closely related to banking ... as to be a proper incident thereto.” This authority would permit us to engage in a variety of banking-related businesses, including the ownership and operation of a savings association, or any entity engaged in consumer finance, equipment leasing, the operation of a computer service bureau (including software development) and mortgage banking and brokerage services. The BHCA does not place territorial restrictions on the domestic activities of nonbank subsidiaries of bank holding companies.

Additionally, bank holding companies that meet certain eligibility requirements prescribed by the BHCA and elect to operate as financial holding companies may engage in, or own shares in companies engaged in, a wider range of nonbanking activities, including securities and insurance underwriting and sales, merchant banking and any other activity that the Federal Reserve, in consultation with the Secretary of the Treasury, determines by regulation or order is financial in nature or incidental to any such financial activity or that the Federal Reserve determines by order to be complementary to any such financial activity and does not pose a substantial risk to the safety or soundness of FDIC-insured institutions or the financial system generally. In order to maintain status as a financial holding company, both the bank holding company and its subsidiary bank must be well-capitalized, well-managed, and have a least a satisfactory Community Reinvestment Act (“CRA”) rating. If the Federal Reserve determines that either the bank

13

holding company or any of its subsidiary banks are not well-capitalized or well-managed, the Federal Reserve will provide a period of time in which to achieve compliance, but during the period of noncompliance, the Federal Reserve may place any additional limitations on it believes to be appropriate. Furthermore, if the Federal Reserve determines that the subsidiary bank has not received a satisfactory CRA rating, the holding company would not be able to commence any new financial activities or acquire a company that engages in such activities. The Company has not elected to become a financial holding company.

Federal law also prohibits any person or company from acquiring “control” of an FDIC-insured depository institution or its holding company without prior notice to the appropriate federal bank regulator.  “Control” is conclusively presumed to exist upon the acquisition of 25% or more of the outstanding voting securities of a bank or bank holding company, but may arise under certain circumstances between 10% and 24.99% ownership.  

Capital Requirements. Bank holding companies are required to maintain capital in accordance with Federal Reserve capital adequacy requirements.  For a discussion of capital requirements, see “—Regulatory Emphasis on Capital” above.

Dividend Payments. The Company’s ability to pay dividends to the Company’s shareholders may be affected by both general corporate law considerations and policies of the Federal Reserve applicable to bank holding companies.  As a Wisconsin corporation, we are subject to the limitations of the Wisconsin Business Corporations Law, which allows us to pay dividends unless, after such dividend, (i) we would not be able to pay the Company’s debts as they become due in the usual course of business or (ii) the Company’s total assets would be less than the sum of the Company’s total liabilities plus any amount that would be needed if we were to be dissolved at the time of the dividend payment, to satisfy the preferential rights upon dissolution of shareholders whose rights are superior to the rights of the shareholders receiving the distribution.

As a general matter, the Federal Reserve has indicated that the board of directors of a bank holding company should eliminate, defer or significantly reduce dividends to shareholders if:  (i) the company’s net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; (ii) the prospective rate of earnings retention is inconsistent with the company’s capital needs and overall current and prospective financial condition; or (iii) the company will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios. The Federal Reserve also possesses enforcement powers over bank holding companies and their non-bank subsidiaries to prevent or remedy actions that represent unsafe or unsound practices or violations of applicable statutes and regulations. Among these powers is the ability to proscribe the payment of dividends by banks and bank holding companies. In addition, under the Basel III Rule, institutions that seek the freedom to pay dividends will have to maintain 2.5% in Common Equity Tier 1 Capital attributable to the capital conservation buffer to be phased in over three years beginning in 2016. See “—Regulatory Emphasis on Capital” above.

Incentive Compensation.There have been a number of developments in recent years focused on incentive compensation plans sponsored by bank holding companies and banks, reflecting recognition by the bank regulatory agencies and Congress that flawed incentive compensation practices in the financial industry were one of many factors contributing to the global financial crisis. Layered on top of that are the abuses in the headlines dealing with product cross-selling incentive plans. The result is interagency guidance on sound incentive compensation practices and proposed rulemaking by the agencies required under Section 956 of the Dodd-Frank Act.

The interagency guidance recognized three core principles: Effective incentive plans should: (i) provide employees incentives that appropriately balance risk and reward; (ii) be compatible with effective controls and risk-management; and (iii) be supported by strong corporate governance, including active and effective oversight by the organization’s board of directors. Much of the guidance addresses large banking organizations and, because of the size and complexity of their operations, the regulators expect those organizations to maintain systematic and formalized policies, procedures, and systems for ensuring that the incentive compensation arrangements for all executive and non-executive employees covered by this guidance are identified and reviewed, and appropriately balance risks and rewards.  Smaller banking organizations like the Company that use incentive compensation arrangements are expected to be less extensive, formalized, and detailed than those of the larger banks. 

Section 956 of the Dodd-Frank Act required the banking agencies, the National Credit Union Administration, the SEC and the Federal Housing Finance Agency to jointly prescribe regulations that prohibit types of incentive-based compensation that encourages inappropriate risk taking and to disclose certain information regarding such plans. On June 10, 2016, the agencies released an updated proposed rule for comment. Section 956 will only apply to banking organizations with assets of greater than $1 billion. We have consolidated assets greater than $1 billion and less than $50 billion and we are considered a Level 3 banking organization under the proposed rules. The proposed rules contain mostly general principles and reporting requirements for Level 3 institutions so there are no specific prescriptions or limits, deferral requirements or claw-back mandates. Risk management and controls are required, as is board or committee level approval and oversight. Management expects to review its incentive plans in light of the proposed rulemaking and guidance and implement policies and procedures that mitigate unreasonable risk. As of December 31, 2017, these rules remain in proposed form.

Monetary Policy.  The monetary policy of the Federal Reserve has a significant effect on the operating results of financial or bank holding companies and their subsidiaries. Among the tools available to the Federal Reserve to affect the money supply are open market transactions in U.S. government securities, changes in the discount rate on bank borrowings and changes in reserve

14

requirements against bank deposits. These means are used in varying combinations to influence overall growth and distribution of bank loans, investments and deposits, and their use may affect interest rates charged on loans or paid on deposits.

Federal Securities Regulation. The Company’s common stock is registered with the SEC under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Consequently, we are subject to the information, proxy solicitation, insider trading and other restrictions and requirements of the SEC under the Exchange Act.

Corporate Governance. The Dodd-Frank Act addressed many investor protection, corporate governance and executive compensation matters that will affect most U.S. publicly traded companies. The Dodd-Frank Act increased shareholder influence over boards of directors by requiring companies to give stockholders a non-binding vote on executive compensation and so-called “golden parachute” payments, and authorizing the SEC to promulgate rules that would allow shareholders to nominate and solicit voters for their own candidates using a company’s proxy materials. The legislation also directed the Federal Reserve to promulgate rules prohibiting excessive compensation paid to executives of bank holding companies, regardless of whether such companies are publicly traded.

Regulation and Supervision of the Bank

General.  The Bank is a Wisconsin -chartered bank. The deposit accounts of the Bank are insured by the FDIC’s Deposit Insurance Fund (DIF) to the maximum extent provided under federal law and FDIC regulations, currently $250,000 per insured depositor category. As a Wisconsin-chartered FDIC-insured bank, the Bank is subject to the examination, supervision, reporting and enforcement requirements of the WDFI, the chartering authority for Wisconsin, and the FDIC, designated by federal law as the primary federal regulator of insured state banks that, like the Bank, are not members of the Federal Reserve System (nonmember banks).  

Deposit Insurance. As an FDIC-insured institution, the Bank is required to pay deposit insurance premium assessments to the FDIC.  The FDIC has adopted a risk-based assessment system whereby FDIC-insured institutions pay insurance premiums at rates based on their risk classification. For institutions like the Bank that are not considered large and highly complex banking organizations, assessments are now based on examination ratings and financial ratios. The total base assessment rates currently range from 1.5 basis points to 30 basis points. At least semi-annually, the FDIC updates its loss and income projections for the DIF and, if needed, increases or decreases the assessment rates, following notice and comment on proposed rulemaking.  The assessment base against which an FDIC-insured institution’s deposit insurance premiums paid to the DIF are calculated is based on its average consolidated total assets less its average tangible equity. This method shifts the burden of deposit insurance premiums toward those large depository institutions that rely on funding the resources other than U.S. deposits. 

The reserve ratio is the FDIC insurance fund balance divided by estimated insured deposits. The Dodd-Frank Act altered the minimum reserve ratio of the DIF, increasing the minimum from 1.15% to 1.35% of the estimated amount of total insured deposits, and eliminating the requirement that the FDIC pay dividends to FDIC-insured institutions when the reserve ratio exceeds certain thresholds.  The reserve ratio reached 1.28% on September 30, 2017.  If the reserve ratio does not reach 1.35% by December 31, 2018 (provided it is at least 1.15%), the FDIC will impose a shortfall assessment on March 31, 2019 on insured depository institutions with total consolidated assets of $10 billion or more. The FDIC will provide assessment credits to insured depository institutions, like the Bank, with total consolidated assets of less than $10 billion for the portion of their regular assessments that contribute to growth in the reserve ratio between 1.15% and 1.35%. The FDIC will apply the credits each quarter that the reserve ratio is at least 1.38% to offset the regular deposit insurance assessments of institutions with credits.

FICO Assessments.   In addition to paying basic deposit insurance assessments, FDIC-insured institutions must pay Financing Corporation (“FICO”) assessments.  FICO is a mixed-ownership governmental corporation chartered by the former Federal Home Loan Bank Board pursuant to the Competitive Equality Banking Act of 1987 to function as a financing vehicle for the recapitalization of the former Federal Savings and Loan Insurance Corporation.  FICO issued 30-year noncallable bonds of approximately $8.1 billion that mature in 2017 through 2019.  FICO’s authority to issue bonds ended on December 12, 1991. Since 1996, federal legislation has required that all FDIC-insured institutions pay assessments to cover interest payments on FICO’s outstanding obligations.  The FICO assessment rate is adjusted quarterly and for the fourth quarter of 2017 was 0.540 basis points (54 cents per $100 dollars of assessable deposits).

Supervisory Assessments.All Wisconsin banks are required to pay supervisory assessments to the WDFI to fund the operations of that agency. The amount of the assessment is calculated on the basis of the Bank’s total assets. During the year ended December 31, 2017, the Bank paid supervisory assessments to the WDFI totaling approximately $85 thousand.

Capital Requirements.  Banks are generally required to maintain capital levels in excess of other businesses.  For a discussion of capital requirements, see “—Regulatory Emphasis on Capital” above.

Liquidity Requirements.  Liquidity is a measure of the ability and ease with which bank assets may be converted to cash. Liquid assets are those that can be converted to cash quickly if needed to meet financial obligations. To remain viable, FDIC-insured institutions must have enough liquid assets to meet their near-term obligations, such as withdrawals by depositors.  Because the global

15

financial crisis was in part a liquidity crisis, Basel III also includes a liquidity framework that requires FDIC-insured institutions to measure their liquidity against specific liquidity tests.One test, referred to asthe Liquidity Coverage Ratio (“LCR”), is designed to ensure that the banking entity has an adequate stock of unencumbered high-quality liquid assets that can be converted easily and immediately in private markets into cash to meet  liquidity needs for a 30-calendar day liquidity stress scenario. The other test, known as the Net Stable Funding Ratio (“NSFR”), is designed to promote more medium- and long-term funding of the assets and activities of FDIC-insured institutions over a one-year horizon. These tests provide an incentive for banks and holding companies to increase their holdings in Treasury securities and other sovereign debt as a component of assets, increase the use of long-term debt as a funding source and rely on stable funding like core deposits (in lieu of brokered deposits).

In addition to liquidity guidelines already in place, the federal bank regulatory agencies implemented the Basel III LCR in September 2014, which requires large financial firms to hold levels of liquid assets sufficient to protect against constraints on their funding during times of financial turmoil, and in 2016 proposed implementation of the NSFR. While these tests only apply to the largest banking organizations in the country, certain elements are expected to filter down to all FDIC-insured institutions. We are reviewing the Company’s liquidity risk management policies in light of the LCR and NSFR.

Stress Testing.  A stress test is an analysis or simulation designed to determine the ability of a given FDIC-insured institution to deal with an economic crisis. In October 2012, U.S. bank regulators unveiled new rules mandated by the Dodd-Frank Act that require the largest U.S. banks to undergo stress tests twice per year, once internally and once conducted by the regulators. Stress tests are not required for banks with less than $10 billion in assets; however, the FDIC now recommends stress testing as a means to identify and quantify loan portfolio risk and the Bank is conducting vendor reviews in order to have this completed by a third-party on a quarterly basis.

Dividend Payments.  The primary source of funds for the Company is dividends from the Bank. Under Wisconsin banking law, Wisconsin-chartered banks generally may pay dividends only out of undivided profits.  The WDFI may restrict the declaration or payment of a dividend by a Wisconsin-chartered bank, such as the Bank. The payment of dividends by any FDIC-insured institution is affected by the requirement to maintain adequate capital pursuant to applicable capital adequacy guidelines and regulations, and a FDIC-insured institution generally is prohibited from paying any dividends if, following payment thereof, the institution would be undercapitalized. As described above, the Bank exceeded its capital requirements under applicable guidelines as of December 31, 2017.  Notwithstanding the availability of funds for dividends, however, the FDIC and the WDFI may prohibit the payment of dividends by the Bank if either or both determine such payment would constitute an unsafe or unsound practice. In addition, under the Basel III Rule, institutions that seek the freedom to pay dividends will have to maintain 2.5% in Common Equity Tier 1 Capital attributable to the capital conservation buffer to be phased in over three years beginning in 2016. See “Regulatory Emphasis on Capital” above.

State Bank Investments and Activities.  The Bank is permitted to make investments and engage in activities directly or through subsidiaries as authorized by Wisconsin law. However, under federal law and FDIC regulations, FDIC-insured state banks are prohibited, subject to certain exceptions, from making or retaining equity investments of a type, or in an amount, that are not permissible for a national bank. Federal law and FDIC regulations also prohibit FDIC-insured state banks and their subsidiaries, subject to certain exceptions, from engaging as principal in any activity that is not permitted for a national bank unless the Bank meets, and continues to meet, its minimum regulatory capital requirements and the FDIC determines that the activity would not pose a significant risk to the DIF. These restrictions have not had, and are not currently expected to have, a material impact on the operations of the Bank.

Insider Transactions.  The Bank is subject to certain restrictions imposed by federal law on “covered transactions” between the Bank and its “affiliates.” The Company is an affiliate of the Bank for purposes of these restrictions, and covered transactions subject to the restrictions include extensions of credit to the Company, investments in the stock or other securities of the Company and the acceptance of the stock or other securities of the Company as collateral for loans made by the Bank.  The Dodd-Frank Act enhanced the requirements for certain transactions with affiliates, including an expansion of the definition of “covered transactions” and an increase in the amount of time for which collateral requirements regarding covered transactions must be maintained.

Certain limitations and reporting requirements are also placed on extensions of credit by the Bank to its directors and officers, to directors and officers of the Company and its subsidiaries, to principal shareholders of the Company and to “related interests” of such directors, officers and principal shareholders.  In addition, federal law and regulations may affect the terms upon which any person who is a director or officer of the Company or the Bank, or a principal shareholder of the Company, may obtain credit from banks with which the Bank maintains a correspondent relationship.  

Safety and Soundness Standards/Risk Management.  The federal banking agencies have adopted guidelines that establish operational and managerial standards to promote the safety and soundness of FDIC-insured institutions. The guidelines set forth standards for internal controls, information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, compensation, fees and benefits, asset quality and earnings.

In general, the safety and soundness guidelines prescribe the goals to be achieved in each area, and each institution is responsible for establishing its own procedures to achieve those goals.  If an institution fails to comply with any of the standards set

16

forth in the guidelines, the FDIC-insured institution’s primary federal regulator may require the institution to submit a plan for achieving and maintaining compliance. If a FDIC-insured institution fails to submit an acceptable compliance plan, or fails in any material respect to implement a compliance plan that has been accepted by its primary federal regulator, the regulator is required to issue an order directing the institution to cure the deficiency. Until the deficiency cited in the regulator’s order is cured, the regulator may restrict the FDIC-insured institution’s rate of growth, require the FDIC-insured institution to increase its capital, restrict the rates the institution pays on deposits or require the institution to take any action the regulator deems appropriate under the circumstances. Noncompliance with the standards established by the safety and soundness guidelines may also constitute grounds for other enforcement action by the federal bank regulatory agencies, including cease and desist orders and civil money penalty assessments.

During the past decade, the bank regulatory agencies have increasingly emphasized the importance of sound risk management processes and strong internal controls when evaluating the activities of the FDIC-insured institutions they supervise.  Properly managing risks has been identified as critical to the conduct of safe and sound banking activities and has become even more important as new technologies, product innovation, and the size and speed of financial transactions have changed the nature of banking markets.  The agencies have identified a spectrum of risks facing a banking institution including, but not limited to, credit, market, liquidity, operational, legal, and reputational risk. In particular, recent regulatory pronouncements have focused on operational risk, which arises from the potential that inadequate information systems, operational problems, breaches in internal controls, fraud, or unforeseen catastrophes will result in unexpected losses. New products and services, third-party risk and cybersecurity are critical sources of operational risk that FDIC-insured institutions must address in the current environment. The Bank is expected to have active board and senior management oversight; adequate policies, procedures, and limits; adequate risk measurement, monitoring, and management information systems; and comprehensive internal controls.

Branching Authority. Wisconsin banks, such as the Bank, have the authority under Wisconsin law to establish branches anywhere in the State of Wisconsin, subject to receipt of all required regulatory approvals.  Federal law permits state and national banks to merge with banks in other states subject to: (i) regulatory approval; (ii) federal and state deposit concentration limits; and (iii) state law limitations requiring the merging bank to have been in existence for a minimum period of time (not to exceed five years) prior to the merger.  The establishment of new interstate branches has historically been permitted only in those states the laws of which expressly authorize such expansion. The Dodd-Frank Act permits well-capitalized and well-managed banks to establish new interstate branches or the acquisition of individual branches of a bank in another state (rather than the acquisition of an out-of-state bank in its entirety) without impediments.

Transaction Account Reserves.Federal Reserve regulations require FDIC-insured institutions to maintain reserves against their transaction accounts (primarily NOW and regular checking accounts). For 2018, the first $16 million of otherwise reservable balances are exempt from reserves and have a zero percent reserve requirement; for transaction accounts aggregating more than $16 million to $122.3 million, the reserve requirement is 3% of total transaction accounts; and for net transaction accounts in excess of $122.3 million, the reserve requirement is 3% up to $122.3 million plus 10% of the aggregate amount of total transaction accounts in excess of $122.3 million.  These reserve requirements are subject to annual adjustment by the Federal Reserve.

Community Reinvestment Act Requirements.  The Community Reinvestment Act requires the Bank to have a continuing and affirmative obligation in a safe and sound manner to help meet the credit needs of its entire community, including low- and moderate-income neighborhoods.  Federal regulators regularly assess the Bank’s record of meeting the credit needs of its communities. Applications for additional acquisitions would be affected by the evaluation of the Bank’s effectiveness in meeting its Community Reinvestment Act requirements.

Anti-Money Laundering.  The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the “USA PATRIOT Act”) is designed to deny terrorists and criminals the ability to obtain access to the U.S. financial system and has significant implications for FDIC-insured institutions, brokers, dealers and other businesses involved in the transfer of money. The USA PATRIOT Act mandates financial services companies to have policies and procedures with respect to measures designed to address any or all of the following matters: (i) customer identification programs; (ii) money laundering; (iii) terrorist financing; (iv) identifying and reporting suspicious activities and currency transactions; (v) currency crimes; and (vi) cooperation between FDIC-insured institutions and law enforcement authorities.

Concentrations in Commercial Real Estate.  Concentration risk exists when FDIC-insured institutions deploy too many assets to any one industry or segment. A concentration in commercial real estate is one example of regulatory concern. The interagency Concentrations in Commercial Real Estate Lending, Sound Risk Management Practices guidance (CRE Guidance) provides supervisory criteria, including the following numerical indicators, to assist bank examiners in identifying banks with potentially significant commercial real estate loan concentrations that may warrant greater supervisory scrutiny: (i) commercial real estate loans exceeding 300% of capital and increasing 50% or more in the preceding three years; or (ii) construction and land development loans exceeding 100% of capital. The CRE Guidance does not limit banks’ levels of commercial real estate lending activities, but rather guides institutions in developing risk management practices and levels of capital that are commensurate with the level and nature of their commercial real estate concentrations. On December 18, 2015, the federal banking agencies issued a statement to reinforce prudent risk-management practices related to CRE lending, having observed substantial growth in many CRE asset and lending markets, increased competitive pressures, rising CRE concentrations in banks, and an easing of CRE underwriting standards. The

17

federal bank agencies reminded FDIC-insured institutions to maintain underwriting discipline and exercise prudent risk-management practices to identify, measure, monitor, and manage the risks arising from CRE lending. In addition, FDIC-insured institutions must maintain capital commensurate with the level and nature of their CRE concentration risk.

Based on the Bank’s loan portfolio as of December 31, 2017, it did not exceed the 300% guideline for commercial real estate loans or the 100% guideline for construction and land development loans.

Consumer Financial Services.The historical structure of federal consumer protection regulation applicable to all providers of consumer financial products and services changed significantly on July 21, 2011, when the CFPB commenced operations to supervise and enforce consumer protection laws. The CFPB has broad rulemaking authority for a wide range of consumer protection laws that apply to all providers of consumer products and services, including the Bank, as well as the authority to prohibit “unfair, deceptive or abusive” acts and practices. The CFPB has examination and enforcement authority over providers with more than $10 billion in assets. FDIC-insured institutions with $10 billion or less in assets, like the Bank, continue to be examined by their applicable bank regulators. We do not currently expect the CFPB’s rules to have a significant impact on the Company’s operations, except for higher compliance costs.

Risks Related to Our Business

We are subject to specific market risks due to our focus on agricultural lending.

We primarily concentrate our lending activities in the state of Wisconsin, which has a significant agricultural economy. Historically, our senior management’s primary business lending experience has been in agricultural lending, with a specific expertise in and focus on dairy and dairy-related businesses. Although we attempt to maintain a diversified customer base and a diversified loan portfolio, we are more heavily dependent upon the agricultural economy than a typical commercial bank. At December 31, 2017, agricultural loans comprised $686.4 million, or approximately 59.7%, of our total loan portfolio, and the Bank also serviced an additional $575.3 million of agricultural loans which generated approximately $5.4 million of servicing fee income.

The agricultural economy is subject to certain risks that are either inherently volatile or are beyond our ability, or the ability of farmers or other participants in the agricultural economy, to predict or control. Some of these risks include, but are not limited to:

• Weather-Related Risks. Severe weather, including such things as drought, hail, excessive rain or other natural disasters, could impact the quantity and quality of feed necessary to support our borrowers’ dairy operations and, in turn, increase

18

their expenses. If significant adverse weather-related events occur, it could impair the ability of borrowers to repay outstanding loans or impair the value of collateral securing loans due to significant property damage, which could either result in loss of revenue or cause us to incur additional expenses.

• Disease-Related Risks. The operations of our dairy farm and dairy-related borrowers depend primarily on their cattle. If the livestock were to contract an illness or disease, the borrowers would incur additional expenses, and the viability of their operations may be compromised if the disease is not properly managed. The existence of a widespread livestock disease or pandemic could have a significant impact on our borrowers’ ability to repay outstanding loans or impair the value of collateral securing loans, which could either result in loss of revenue or cause us to incur additional expenses.

• Real Property Value. Our dairy farm and dairy-related borrowers tend to grow and produce much of their feed as opposed to purchasing it from third parties, unlike many dairy farmers in other parts of the country. While this means they are often less subject to fluctuations in feed prices, they require more land. Accordingly, declines in real property values in the areas in which we operate could result in a deterioration of the credit quality of our borrowers or an increase in the number of loan delinquencies, default and charge-offs, and could reduce the value of any collateral we realize following a default on agricultural loans.

• Market Prices. Agricultural markets are sensitive to real and perceived changes in supply and demand of agricultural products, and given that approximately 90% of our agricultural lending is to dairy farms, the credit quality of a substantial portion of our loan portfolio is closely related to the performance of, and supply and demand in, this sub-sector of the agricultural market. For example, the success of a dairy operation hinges in large part on the cost of feed and the price of milk. When feed costs are high and milk prices are low, it places a strain on our dairy borrowers’ business, which may impair their ability to repay their outstanding loans to us.

• Governmental Policies and Regulations. Our agricultural loans are dependent on the profitable operation and management of the farm properties securing the loans and their cash flows, and government policies and regulations (including the availability of price supports for crops and other agricultural products (in particular, milk), subsidies, or government-sponsored crop insurance) are outside the control of our borrowers and may affect the successful operation of a farm.

• Changing Consumer Preferences.The business of dairy farms and dairy-related borrowers is subject to changing consumer preferences and nutritional and health-related concerns.  Periodically, medical and other studies are released which raise concerns over the healthfulness of cow’s milk in the human diet.  As a result of studies or other cultural influences, the dairy industry could be affected by certain consumer concerns about dairy products, such as the fat, cholesterol, calorie, sodium and lactose content of such products, which could reduce demand for dairy products and negatively affect dairy-related revenue.

Our focus on local markets and agricultural lending creates credit concentration risks.

Credit risk is primarily related to the risk that a borrower will not be able to repay some or all of its obligations to us. Concentrations of credit risk occur when the aggregate amount owed by one borrower, a group of related borrowers, or borrowers within the same or related markets, industries or groups, represent a relatively large percentage of the total capital or total credit extended by a bank. Although each loan in a concentration may be of sound quality, concentration risks represent a risk not present when the same loan amounts are extended to a more diversified group of borrowers. Loans concentrated in one borrower depend, to a large degree, upon the financial capability and character of the individual borrower. Loans made to a group of related borrowers can be susceptible to financial problems experienced by one or a few members of that group. Loans made to borrowers that are part of the same or related industries or groups, or that are located in the same market area, can all be adversely impacted with respect to their ability to repay some or all of their obligations when adverse conditions prevail in the broader economy generally, in the market specifically or even within just the respective industries or groups.

Our lending is primarily to borrowers located or doing business in Wisconsin. Furthermore, at December 31, 2017, we had certain loan-type concentrations of credit risk, specifically in agricultural lending, which are described in more detail in the section of this Form 10-K entitled “Item 1 - Business—Lending Activities” and “Item 1 - Business—General—Market.” Because of the concentration of agricultural loans in our lending portfolio and the volume of our borrowers in regions dependent upon agriculture, we could be disproportionately affected by changes in the agricultural industry relative to others because these high concentrations present a risk to our lending operations. If any of these borrowers becomes unable to repay their loan obligations for any reason, our nonperforming loans, our allowance for loan losses, and our provision for loan losses could increase significantly, which could have a material adverse effect on our business, financial condition and results of operations.

19

Our business is dependent on local economies, and a regional or local economic downturn affecting Wisconsin may magnify the adverse effects and consequences to us.

We operate as a community-oriented business bank, with a focus on servicing both business customers and individuals in our market areas, which include our headquarters in Manitowoc, full-service branches in Appleton, Green Bay, and Stevens Point, and a loan production office in each of Darlington, Eau Claire, Fond du Lac, and Sheboygan. Although we have a primary focus on agricultural and business banking, future growth opportunities will depend largely on market area penetration, market area growth and our ability to compete for traditional banking business within our market areas. We anticipate that as a result of this concentration, a downturn in the general economy in our market areas, including Wisconsin specifically, could increase the risk of loss associated with our loan portfolio. Although economic conditions in our markets have been generally strong, there can be no assurance that such conditions will continue to prevail.

Volatility in commodity prices may adversely affect our financial condition and results of operations.

At December 31, 2017, approximately 59.7% of our total loan portfolio was comprised of agricultural loans. Volatility in certain commodity prices, including milk, could adversely impact the ability of those borrowers to perform under the terms of their borrowing arrangements with us. In terms of the dairy industry, milk prices have fluctuated. For the 15-year period ended December 31, 2017, the per-year average Class III milk price (a weighted average price of all uses of milk in a particular milk order) in the United States paid to producers has ranged from an average low price of $11.36 per hundredweight (cwt) in 2009 to an average high price of $22.34 per cwt in 2014, according to the University of Wisconsin - Madison.  During 2017, the Class III milk price was an average of $16.17 per cwt.  “Hundredweight” or “cwt” is a measure equal to 100 pounds of milk shipped.  A decrease in milk prices may result in an increase in the number of non-performing loans in our agricultural portfolio, which could have a material adverse effect on our financial condition, earnings and capital.

Our business is significantly dependent on the real estate markets where we operate, as a large portion of our loan portfolio is secured by real estate.

At December 31, 2017, approximately 62.9% of our aggregate loan portfolio, comprising our agriculture real estate loans (including agricultural construction loans), commercial real estate loans and residential real estate loans, was primarily secured by interests in real estate predominantly located in Wisconsin.  Additionally, some of our other lending occasionally involves taking real estate as primary or secondary collateral. Real property values in Wisconsin may be different from, and in some instances worse than, real property values in other markets or in the United States as a whole, and may be affected by a variety of factors outside our control and the control of our borrowers, including national and local economic conditions generally. The market value of real estate securing our real estate loans can fluctuate significantly in a short period of time as a result of market conditions in the geographic area in which the real estate is located.  Although a significant portion of such loans is secured by real estate as a secondary form of repayment, adverse developments affecting real estate values in Wisconsin could increase the credit risk associated with our loan portfolio and cause an increase in the number of loan delinquencies, defaults and charge-offs.  Additionally, real estate lending typically involves higher loan principal amounts and the repayment of the loans generally is dependent, in large part, on sufficient income from the properties securing the loans to cover operating expenses and debt service.  Economic events or governmental regulations outside of the control of the borrower or lender could negatively impact the future cash flow and market values of the affected properties.

If problems develop in the real estate market, particularly within Wisconsin, the value of collateral securing our real estate loans could decline.  In such case, we may not be able to realize the amount of security that we anticipated at the time of originating the loan, which could cause us to increase our provision for loan losses and adversely affect our operating results, financial condition and/or capital.

Our commercial real estate and commercial loans generally carry greater credit risk than loans secured by owner occupied one-to-four family real estate, and our credit risk may increase if we succeed in our plan to increase our commercial lending.

At December 31, 2017, $407.0 million, or approximately 35.4%, of our loan portfolio consisted of commercial real estate and commercial loans. Given their generally larger balances and the complexity of the underlying collateral, commercial real estate and commercial loans generally expose a lender to greater credit risk than loans secured by owner occupied one-to-four family real estate.  For commercial real estate loans, the principal risk is that repayment is generally dependent on income from tenant leases being generated in amounts sufficient to cover operating expenses and debt service.  For commercial loans, the principal risk is that repayment is generally dependent upon the successful operation of the borrower’s business.  If loans that are collateralized by real estate or other business assets become troubled and the value of the collateral has been significantly impaired, then we may not be able to recover the full contractual amount of principal and interest that we anticipated at the time we originated the loan, which could cause us to increase our provision for loan losses and would adversely affect our operating results.

20

We are subject to environmental liability risk associated with real estate collateral securing our loans.

A significant portion of our loan portfolio is secured by real property. Under certain circumstances, we may take title to the real property collateral through foreclosure or other means. As the titleholder of the property, we may be responsible for environmental risks, such as hazardous materials, which attach to the property. For these reasons, prior to extending credit, we have an environmental risk assessment program to identify any known environmental risks associated with the real property that will secure our loans. In addition, we routinely inspect properties following the taking of title. When environmental risks are found, environmental laws and regulations may prescribe our approach to remediation. As a result, while we have ownership of a property, we may incur substantial expense and bear potential liability for any damages caused. The environmental risks may also materially reduce the property's value or limit our ability to use or sell the property. We also cannot guarantee that our environmental risk assessment will detect all environmental issues relating to a property, which could subject us to additional liability.

Our business depends on our ability to successfully manage credit risk.

The operation of our business requires us to manage credit risk. As a lender, we are exposed to the risk that our borrowers will be unable to repay their loans and leases according to their terms, and that the collateral securing repayment of their loans, if any, may not be sufficient to ensure repayment. In addition, there are risks inherent in making any loan, including risks with respect to the period of time over which the loan may be repaid, risks relating to proper loan underwriting, risks resulting from changes in economic and industry conditions and risks inherent in dealing with individual borrowers, including the risk that a borrower may not provide information to us about its business in a timely manner, and/or may present inaccurate or incomplete information to us, and risks relating to the value of collateral. In order to manage credit risk successfully, we must, among other things, maintain disciplined and prudent underwriting standards and ensure that our bankers follow those standards. The weakening of these standards for any reason, such as an attempt to attract higher yielding loans, a lack of discipline or diligence by our employees in underwriting and monitoring loans, the inability of our employees to adequately adapt policies and procedures to changes in economic or any other conditions affecting borrowers and the quality of our loan portfolio, may result in loan defaults, foreclosures and additional charge-offs and may necessitate that we significantly increase our allowance for loan and lease losses, each of which could adversely affect our net income. As a result, our inability to successfully manage credit risk could have a material adverse effect on our business, financial condition or results of operations.

Strong competition could hurt our earnings and slow growth.

We face intense competition in making loans and attracting deposits. Price competition for loans and deposits sometimes results in us charging lower interest rates on our loans and paying higher interest rates on our deposits, which may reduce our net interest income.  Many of the institutions with which we compete have substantially greater resources and lending limits than we have and may offer services that we do not provide. We also face competition for agricultural loans from participants in the nationwide Farm Credit System and much larger regional, national and global banks.  Competition also makes it more difficult and costly to attract and retain qualified employees.  We expect competition to increase in the future as a result of legislative, regulatory and technological changes and the continuing trend of non-bank competition in the financial services industry. If we are not able to effectively compete in our market areas and targeted business segments, our profitability may be negatively affected.

Consumers and businesses are increasingly using non-banks to complete their financial transactions, which could adversely affect our business and results of operations.

Technology and other changes are allowing consumers and businesses to complete financial transactions that historically have involved banks through alternative methods. For example, the wide acceptance of internet-based commerce has resulted in a number of alternative payment processing systems and lending platforms in which banks play only minor roles. Customers can now maintain funds in prepaid debit cards or digital currencies, and pay bills and transfer funds directly without the direct assistance of banks. The diminishing role of banks as financial intermediaries has resulted and could continue to 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 potential loss of lower cost deposits as a source of funds could have a material adverse effect on our business, financial condition and results of operations.

Our ability to maintain our reputation is critical to the success of our business, and the failure to do so may materially adversely affect our performance.

We have benefited from strong relationships with our customers, and also from our relationships with financial intermediaries. As a result, our reputation is an important component of our business. A key component of our business strategy is to leverage our reputation for customer service and knowledge of our customers’ needs and businesses to expand our presence by capturing new

21

business opportunities from existing and prospective customers in and outside of our local market areas. We strive to conduct our business in a manner that enhances our reputation. We aim to enhance our reputation, in part, by recruiting, hiring and retaining employees who share our core values of being an integral part of the communities and markets we serve, who are able to connect with customers through on-site visits and knowledge of our customers’ businesses, and who care about and deliver superior service to our customers. If our reputation is negatively affected by the actions of our employees, by our inability to conduct our operations in a manner that is appealing to current or prospective customers, or by events beyond our control, our business and operating results may be adversely affected.

Changes in interest rates may hurt our earnings and asset value.

Like other financial institutions, we are subject to interest rate risk. Our primary source of income is net interest income, which is the difference between interest earned on interest-earning assets (consisting primarily of loans and securities) and the interest paid on interest-bearing liabilities (consisting primarily of deposits and borrowings). Changes in both the general level of interest rates and in the difference between short-term and long-term rates can affect our net interest income. Interest rates are highly sensitive to many factors, including government monetary policies, domestic and international economic and political conditions and other factors beyond our control.

While we pursue an asset/liability strategy designed to mitigate our risk from changes in interest rates, including by seeking to originate variable rate loans and balancing the respective terms of assets and liabilities, changes in interest rates may still have a material adverse effect on our financial condition and results of operations. Changes in the level of interest rates also may negatively affect our ability to originate loans, the value of our assets and liabilities and our ability to realize gains from the sale of our assets, all of which could affect our earnings.

Monetary policies and regulations of the Federal Reserve could adversely affect our business, financial condition and results of operations.

In addition to being affected by general economic conditions, our earnings and growth are affected by the policies of the Federal Reserve. An important function of the Federal Reserve is to regulate the money supply and credit conditions. Among the instruments used by the Federal Reserve to implement these objectives are open market operations in U.S. government securities, adjustments of the discount rate, and changes in reserve requirements against bank deposits. These instruments are used in varying combinations to influence overall economic growth and the distribution of credit, bank loans, investments and deposits. Their use also affects interest rates charged on loans or paid on deposits.

The monetary policies and regulations of the Federal Reserve have had a significant effect on the operating results of commercial banks in the past and are expected to continue to do so in the future. The specific effects of such policies upon our business, financial condition and results of operations cannot be predicted.

If our allowance for loan losses is not sufficient to cover actual loan losses, our earnings and capital could decrease.

At December 31, 2017, our allowance for loan losses totaled $13.2 million, which represented 1.15% of gross loans. We make various assumptions and judgments about the collectability of our loan portfolio, including the creditworthiness of our borrowers and the value of the real estate and other assets serving as collateral for our loans. In determining the amount of the allowance for loan losses, we review our loss and delinquency experience, and we evaluate other factors including, among other things, current economic conditions. If our assumptions are incorrect, or if delinquencies or non-performing loans increase, our allowance for loan losses may not be sufficient to cover losses inherent in our loan portfolio, which would require additions to our allowance, and could decrease our net income or reduce our capital.

In addition, our regulators, as an integral part of their examination process, periodically review the allowance for loan losses and may require us to increase the allowance for loan losses by recognizing additional provisions for loan losses charged to expense, or to charge off loans, which, net of any recoveries, would decrease the allowance for loan losses. Any such additional provisions for loan losses or charge-offs could have a material adverse effect on our financial condition and results of operations.

We rely on the accuracy and completeness of information about our customers and counterparties, and inaccurate or incomplete information could subject us to various risks.

In deciding whether to extend credit or enter into other transactions with our customers and counterparties, we may rely on information furnished by or on behalf of customers and counterparties, including financial statements and other financial information. We may also rely on representations as to the accuracy and completeness of such information and, with respect to financial statements, on reports of independent auditors.

22

While we strive to verify the accuracy and sufficiency of such information, if this information is inaccurate or incomplete, we may be subject to loan losses, regulatory action, reputational harm, or other adverse effects on the operation of our business, results of operations, or financial condition.

We depend on our management team to implement our business strategy and on our relationship managers to maintain and grow our agricultural and commercial relationships, and we could be harmed by the loss of their services.

We are dependent upon the services and expertise of our founders and the other members of our management team who direct our strategy and operations, especially relating to our agricultural lending focus, and we have benefited from our management’s extensive banking knowledge and experience in this regard. We also rely heavily upon the talents, experience and customer relationships of our loan officers and have benefited from their expertise and relationship-building skills, especially with respect to our agricultural and commercial lending. Members of our executive management team and our seasoned loan officers could be difficult to replace. Our loss of the services of one or more of these persons, or our inability to hire additional qualified personnel, could impact our ability to implement our business strategy and could have a material adverse effect on our business and results of operations.

Limits on our ability to use brokered deposits as part of our funding strategy may adversely affect our ability to grow.

A “brokered deposit” is any deposit that is obtained from or through the mediation or assistance of a deposit broker, which includes larger correspondent banks and securities brokerage firms. These deposit brokers attract deposits from individuals and companies throughout the country and internationally whose deposit decisions are based almost exclusively on obtaining the highest interest rates. We have used brokered deposits in the past, and we intend to continue to use brokered deposits as one of our funding sources to support future growth. At December 31, 2017, brokered deposits represented approximately 25.5% of our total deposits and equaled $282.6 million. There are risks associated with using brokered deposits. In order to continue to maintain our level of brokered deposits, we may be forced to pay higher interest rates than contemplated by our asset-liability pricing strategy. In addition, banks that become less than “well capitalized” under applicable regulatory capital requirements may be restricted in their ability to accept or prohibited from accepting brokered deposits.  In addition, banks not considered to be “well capitalized” are subject to a cap on interest rates paid to depositors as published by the FDIC. Such depositor interest rate caps could impede our ability to raise local deposits to replace brokered deposits no longer available if we were not considered to be “well capitalized.”  If brokered deposits become more difficult to access, we will have to seek alternative funding sources in order to continue to fund our growth. This may include increasing our reliance on the FHLB borrowings, attempting to attract non-brokered deposits, reducing our available for sale securities portfolio and selling loans, potentially at a time when pricing may be unfavorable, which may increase our funding costs and reduce our net interest income and net income.  There can be no assurance that brokered deposits will be available or, if available, sufficient to support our continued growth.

Liquidity risks could affect operations and jeopardize our business, financial condition and results of operations.

Liquidity risk is the risk that we will not be able to meet our obligations, including financial commitments, as they come due and is inherent in our operations. An inability to raise funds through deposits, borrowings, the sale of loans and/or investment securities and from other sources could have a substantial negative effect on our liquidity. Our most important source of funds consists of our customer deposits, which we supplement with other sources such as brokered deposits. Deposit balances can decrease for a variety of reasons, including when customers perceive alternative investments, such as the stock market, as providing a better risk/return tradeoff. If customers move money out of bank deposits and into other investments, we could lose a relatively low cost source of funds. This loss would require us to seek other funding alternatives, including brokered deposits, in order to continue to grow, thereby increasing our funding costs and reducing our net interest income and net income.

Our access to funding sources in amounts adequate to finance or capitalize our activities or on terms that are acceptable to us could be impaired by factors that affect us directly or the financial services industry or economy in general, such as disruptions in the financial markets or negative views and expectations about the prospects for the financial services industry. Economic conditions and a loss of confidence in financial institutions may increase our cost of funding and limit access to certain customary sources of capital, including inter-bank borrowings, repurchase agreements and borrowings from the discount window of the Federal Reserve System. There is also the potential risk that collateral calls with respect to our repurchase agreements could reduce our available liquidity.

Any decline in available funding could adversely impact our ability to continue to implement our business plan, including originating loans, investing in securities, meeting our expenses or fulfilling obligations such as repaying our borrowings and meeting deposit withdrawal demands, any of which could have a material adverse impact on our liquidity, business, financial condition and results of operations.

23

If a significant portion of any future unrealized losses in our portfolio of investment securities were to become other than temporarily impaired with credit losses, we would recognize a material charge to our earnings, and our capital ratios would be adversely impacted.

Factors beyond our control can significantly influence the fair value of securities in our portfolio and can cause potential adverse changes to the fair value of those securities. These factors include, but are not limited to, changes in interest rates, rating agency downgrades of the securities, defaults by the issuer or individual mortgagors with respect to the underlying securities, and instability in the credit markets. Any of the foregoing factors could cause an other than temporary impairment (“OTTI”) in future periods and result in realized losses.

We analyze our investment securities quarterly to determine whether, in the opinion of management, any of the securities have OTTI. To the extent that any portion of the unrealized losses in our portfolio of investment securities is determined to have OTTI and is credit-loss related, we will recognize a charge to our earnings in the quarter during which such determination is made, and our capital ratios will be adversely impacted. Generally, a fixed income security is determined to have OTTI when it appears unlikely that we will receive all of the principal and interest due in accordance with the original terms of the investment. In addition to credit losses, losses are recognized for a security with an unrealized loss if the Company has the intent to sell the security or if it is more likely than not that the Company will be required to sell the security before collection of the principal amount.

The occurrence of fraudulent activity, breaches or failures of our information security controls or cybersecurity-related incidents could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

As a bank, we are susceptible to fraudulent activity, information security breaches and cybersecurity-related incidents that may be committed against us or our clients, which may result in financial losses or increased costs to us or our clients, disclosure or misuse of our information or our client information, misappropriation of assets, privacy breaches against our clients, litigation or damage to our reputation.  Such fraudulent activity may take many forms, including check fraud, electronic fraud, wire fraud, phishing, social engineering and other dishonest acts.  Information security breaches and cybersecurity-related incidents may include fraudulent or unauthorized access to systems used by us or our clients, denial or degradation of service attacks and malware or other cyber-attacks.  

In recent periods, there continues to be a rise in electronic fraudulent activity, security breaches and cyber-attacks within the financial services industry, especially in the commercial banking sector due to cyber criminals targeting commercial bank accounts.  Moreover, in recent periods, several large corporations, including financial institutions and retail companies, have suffered major data breaches, in some cases exposing not only confidential and proprietary corporate information, but also sensitive financial and other personal information of their customers and employees and subjecting them to potential fraudulent activity. Some of our clients may have been affected by these breaches, which could increase their risks of identity theft and other fraudulent activity that could involve their accounts with us.

Information pertaining to us and our clients is maintained, and transactions are executed, on networks and systems maintained by us and certain third party partners, such as our online banking, mobile banking or accounting systems.  The secure maintenance and transmission of confidential information, as well as execution of transactions over these systems, are essential to protect us and our clients against fraud and security breaches and to maintain the confidence of our clients.  Breaches of information security also may occur through intentional or unintentional acts by those having access to our systems or the confidential information of our clients, including employees.  In addition, increases in criminal activity levels and sophistication, advances in computer capabilities, new discoveries, vulnerabilities in third party technologies (including browsers and operating systems) or other developments could result in a compromise or breach of the technology, processes and controls that we use to prevent fraudulent transactions and to protect data about us, our clients and underlying transactions, as well as the technology used by our clients to access our systems.  Our third party partners’ inability to anticipate, or failure to adequately mitigate, breaches of security could result in a number of negative events, including losses to us or our clients, loss of business or clients, damage to our reputation, the incurrence of additional expenses, disruption to our business, additional regulatory scrutiny or penalties or our exposure to civil litigation and possible financial liability, any of which could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

We depend on information technology and telecommunications systems of third parties, and any systems failures, interruptions or data breaches involving these systems could adversely affect our operations and financial condition.

Our business is highly dependent on the successful and uninterrupted functioning of our information technology and telecommunications systems, third party servicers, accounting systems, mobile and online banking platforms and financial intermediaries.  We outsource to third parties many of our major systems, such as data processing and mobile and online banking.  The failure of these systems, or the termination of a third party software license or service agreement on which any of these systems is based, could interrupt our operations.  Because our information technology and telecommunications systems interface with and depend on third party systems, we could experience service denials if demand for such services exceeds capacity or such third party systems fail or experience interruptions.  A system failure or service denial could result in a deterioration of our ability to process loans or gather deposits and provide customer service, compromise our ability to operate effectively, result in potential noncompliance

24

with applicable laws or regulations, damage our reputation, result in a loss of customer business or subject us to additional regulatory scrutiny and possible financial liability, any of which could have a material adverse effect on business, financial condition, results of operations and growth prospects.  In addition, failures of third parties to comply with applicable laws and regulations, or fraud or misconduct on the part of employees of any of these third parties, could disrupt our operations or adversely affect our reputation.

It may be difficult for us to replace some of our third party vendors, particularly vendors providing our core banking and information services, in a timely manner if they are unwilling or unable to provide us with these services in the future for any reason and even if we are able to replace them, it may be at higher cost or result in the loss of customers.  Any such events could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

Our operations rely heavily on the secure processing, storage and transmission of information and the monitoring of a large number of transactions on a minute-by-minute basis, and even a short interruption in service could have significant consequences.  We also interact with and rely on retailers, for whom we process transactions, as well as financial counterparties and regulators. Each of these third parties may be targets of the same types of fraudulent activity, computer break-ins and other cyber security breaches described above, and the cyber security measures that they maintain to mitigate the risk of such activity may be different than our own and may be inadequate.

As a result of financial entities and technology systems becoming more interdependent and complex, a cyber incident, information breach or loss, or technology failure that compromises the systems or data of one or more financial entities could have a material impact on counterparties or other market participants, including ourselves.  As a result of the foregoing, our ability to conduct business may be adversely affected by any significant disruptions to us or to third parties with whom we interact.

We rely on other companies to provide certain key components of our business infrastructure.

Third-party service providers provide certain key components of our business infrastructure, such as data processing and deposit processing systems, mobile payment systems, internet connections, and network access. While we have selected these third-party service providers carefully, we do not control their operations. Any failure by these third parties to perform or provide agreed-upon goods and services for any reason or their poor performance of services could adversely affect our ability to deliver products and services to our customers and otherwise to conduct our business. Replacing these third-party service providers could also entail significant delay and expense.

We may face risks with respect to future acquisitions.

We may continue to attempt to expand our business in Wisconsin or other states through mergers and acquisitions.  We anticipate that we will seek targets that are culturally similar to us, have experienced management and possess either significant market presence or have potential for improved profitability through economies of scale or expanded services. In addition to the general risks associated with our growth plans, acquiring other banks, businesses or branches involves various risks commonly associated with acquisitions, including, among other things, the following:

• the time and costs associated with identifying and evaluating potential acquisition and merger targets;

• unexpected delays, complications or expenses resulting from regulatory approval requirements or other conditions to closing;

• inaccuracies in the estimates and judgments used to evaluate credit, operations, management and market risks with respect to the target institution;

• the time and costs of evaluating new markets, hiring experienced local management, and the time lags between these activities and the generation of sufficient assets and deposits to support the costs of the expansion;

• our ability to finance an acquisition and possible dilution to our existing shareholders;

• the diversion of our management’s attention to the negotiation of a transaction;

• the incurrence of an impairment of goodwill associated with an acquisition and adverse effects on our results of operations;

• entry into new markets where we lack experience; and

• risks associated with integrating the operations and personnel of the acquired business in a manner that permits growth opportunities and does not materially disrupt existing customer relationships or result in decreased revenues resulting from any loss of customers.

25

With respect to the risks particularly associated with the integration of an acquired business, we may encounter a number of difficulties, such as: (1) customer loss and revenue loss; (2) the loss of key employees; (3) the disruption of our operations and business; (4) our inability to maintain and increase competitive presence; (5) possible inconsistencies in standards, control procedures and policies; and/or (6) unexpected problems with costs, operations, personnel, technology and credit.

In addition to the risks posed by the integration process itself, the focus of management’s attention and effort on integration may result in a lack of sufficient management attention to other important issues, causing harm to our business. Also, general market and economic conditions or governmental actions affecting the financial industry generally may inhibit our successful integration of an acquired business.  Failure to realize the expected revenue increases, cost savings, increases in geographic or product presence and/or other projected benefits from an acquisition could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

If we fail to successfully keep pace with technological change, our business could be materially adversely affected.

The financial services industry is continually undergoing rapid technological change with frequent introductions of new technology-driven products and services. The effective use of technology increases efficiency and enables financial institutions to better serve customers and to reduce costs. Our future success depends, in part, upon our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands, as well as to create additional efficiencies in our operations. Failure to successfully keep pace with technological change affecting the financial services industry generally, and virtual banking in particular, could have a material adverse impact on our business and, in turn, our financial condition and results of operations.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

We designed our disclosure controls and procedures to reasonably assure that information we must disclose in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected and any failure or circumvention of our controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business results of operations and financial condition.

If our risk management framework does not effectively identify or mitigate our risks, we could suffer losses.

Our risk management framework seeks to mitigate risk and appropriately balance risk and return. We have established processes and procedures intended to identify, measure, monitor and report the types of risk to which we are subject, including credit risk, operations risk, compliance risk, reputation risk, strategic risk, market risk and liquidity risk. We seek to monitor and control our risk exposure through a framework of policies, procedures, monitoring and reporting requirements. There may be risks that exist, or that develop in the future, that we have not appropriately anticipated, identified or mitigated. If our risk management framework does not effectively identify or mitigate our risks, we could suffer unexpected losses and could be materially adversely affected.

We incur significant costs as a result of operating as a public company, and our management is required to devote substantial time to new compliance initiatives relating to our financial and accounting systems, procedures and controls in order to satisfy our new public company reporting requirements.

As a public company, we incur significant legal, accounting and other expenses that we did not incur as a private company, and these expenses may increase even more after we are no longer an “emerging growth company.” We have made, and will continue to make, changes to our internal controls and procedures for financial reporting and accounting systems to meet our reporting obligations as a stand-alone public company. These obligations increase our operating expenses and could divert management’s attention from other aspects of our business.  We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, Dodd-Frank Act, as well as rules adopted, and to be adopted, by the SEC, and the Nasdaq Global Market, except for such requirements that we may elect not to comply with during the period we are an emerging growth company, which could require us to further upgrade our systems and/or hire additional staff, which would increase our operating costs. Our management and other personnel need to devote a substantial amount of time to these compliance initiatives. Moreover, we expect these rules and regulations to substantially increase our legal and financial compliance costs and to make some activities more time-consuming and costly. The increased costs may cause

26

us to incur losses. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements.

As an “emerging growth company,” we are taking advantage of certain temporary exemptions from various reporting requirements, including reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and an exemption from the requirement to obtain an attestation from our auditors on management’s assessment of our internal control over financial reporting. When these exemptions cease to apply, we expect to incur additional expenses and devote increased management effort toward ensuring compliance with them.

The soundness of other financial institutions could adversely affect us.

Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships. We have exposure to many different industries and counterparties, and we routinely execute transactions with counterparties in the financial services industry, including brokers and dealers, commercial banks, investment banks and other institutional clients. Many of these transactions expose us to credit risk in the event of default by our counterparty or client. In addition, our credit risk may be exacerbated when the collateral held by us cannot be realized or is liquidated at prices not sufficient to recover the full amount of the loan or derivative exposure due us. There is no assurance that any such losses would not materially and adversely affect our results of operations or earnings.

Risks Related to Our Industry

We may be materially and adversely affected by the highly regulated environment in which we operate.

We are subject to extensive federal and state regulation, supervision and examination. A more detailed description of the primary federal and state banking laws and regulations that affect us is contained in Item 1 of this Form 10-K in the section captioned “Supervision and Regulation.” Banking regulations are primarily intended to protect depositors’ funds, FDIC funds, customers and the banking system as a whole, rather than our stockholders.  These regulations affect our lending practices, capital structure, investment practices, dividend policy and growth, among other things.

As a bank holding company, we are subject to extensive regulation and supervision and undergo periodic examinations by our regulators, who have extensive discretion and authority to prevent or remedy unsafe or unsound practices or violations of law by banks and financial holding companies.  Failure to comply with applicable laws, regulations or policies could result in sanctions by regulatory agencies, civil monetary penalties and/or damage to our reputation, which could have a material adverse effect on us.  Although we have policies and procedures designed to mitigate the risk of any such violations, there can be no assurance that such violations will not occur.

Current or proposed regulatory or legislative changes to laws applicable to the financial industry may impact the profitability of our business activities and may change certain of our business practices, including our ability to offer new products, obtain financing, attract deposits, make loans and achieve satisfactory interest spreads, and could expose us to additional costs, including increased compliance costs. These changes also may require us to invest significant management attention and resources to make any necessary changes to operations in order to comply and could therefore also materially and adversely affect our business, financial condition and results of operations.

The financial services industry, as well as the broader economy, may be subject to new legislation, regulation, and government policy.

At this time, it is difficult to predict the legislative and regulatory changes that will occur in the future, especially as lawmakers have advocated for significant reduction of financial services regulation, to include amendments to the Dodd-Frank Act and structural changes to the CFPB. The current presidential administration and Congress also may cause broader economic changes due to changes in governing ideology and governing style. New appointments to the Federal Reserve could affect monetary policy and interest rates, and changes in fiscal policy could affect broader patterns of trade and economic growth. Future legislation, regulation, and government policy could affect the banking industry as a whole, including our business and results of operations, in ways that are difficult to predict. In addition, our results of operations also could be adversely affected by changes in the way in which existing statutes and regulations are interpreted or applied by courts and government agencies.

27

Our growth or future losses may require us to raise additional capital in the future, but that capital may not be available when it is needed or the cost of that capital may be very high.

We are required by our regulators to maintain adequate levels of capital to support our operations. We believe our current level of capital is sufficient to permit us to maintain regulatory capital compliance for the foreseeable future. Nonetheless, we may at some point need to raise additional capital to support continued growth or to address losses.

Our ability to raise additional capital, if needed, will depend on conditions in the capital markets at that time, which are outside of our control, and on our financial condition and performance. Accordingly, we may not be able to raise additional capital if needed on terms that are acceptable to us, or at all. If we cannot raise additional capital when needed, our operations and our financial condition could be materially and adversely affected. In addition, if we are unable to raise additional capital if required by the Federal Reserve, we may be subject to adverse regulatory action.

We face a risk of noncompliance with and enforcement actions under the Bank Secrecy Act and other anti-money laundering statutes and regulations.

We maintain systems and procedures designed to ensure that we comply with applicable laws and regulations. The federal Bank Secrecy Act, the USA PATRIOT Act, and other laws and regulations require financial institutions, among other duties, to institute and maintain effective anti-money laundering programs and file suspicious activity and currency transaction reports as appropriate. The federal Financial Crimes Enforcement Network, established by the Treasury to administer the Bank Secrecy Act, is authorized to impose significant civil money penalties for violations of those requirements and has recently engaged in coordinated enforcement efforts with the individual federal banking regulators, as well as the U.S. Department of Justice, Drug Enforcement Administration and Internal Revenue Service. Federal and state bank regulators also have begun to focus on compliance with Bank Secrecy Act and anti-money laundering regulations. If our policies, procedures and systems are deemed deficient, we would be subject to liability, including fines and regulatory actions such as restrictions on our ability to pay dividends and the necessity to obtain regulatory approvals to proceed with certain aspects of our business plan, including future acquisition plans, which would negatively impact our business, financial condition and results of operations. Failure to maintain and implement adequate programs to combat money laundering and terrorist financing could also have serious reputational consequences for us.

Changes in accounting standards and policies may negatively affect our performance.

Our accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. From time to time there are changes in the financial accounting and reporting standards that govern the preparation of our financial statements. These changes can be difficult to predict and can materially impact how we report and record our financial condition and results of operations. In some cases, we could be required to apply a new or revised accounting standard retroactively, which could have a negative impact on our reported results.

A new accounting standard may require us to increase our allowance for loan losses and may have a material adverse effect on our financial condition and results of operations.

The FASB has adopted a new accounting standard that will be effective for the Company and the Bank for our first fiscal year after December 15, 2019.  This standard, referred to as Current Expected Credit Loss, or CECL, will require financial institutions to determine periodic estimates of lifetime expected credit losses on loans, and recognize the expected credit losses as allowances for loan losses.  This will change the current method of providing allowances for loan losses that are probable, which may require us to increase our allowance for loan losses, and to greatly increase the types of data we will need to collect and review to determine the appropriate level of the allowance for loan losses. Any increase in our allowance for loan losses or expenses incurred to determine the appropriate level of the allowance for loan losses may have a material adverse effect on our financial condition and results of operations.

Our ability to pay dividends is dependent upon the Bank’s performance.

The Company’s only source of funds to pay dividends is dividends or other distributions it may receive directly from the Bank. The Company’s payment of dividends in the future, if any, will be subject to legal, regulatory and contractual restrictions (including with respect to junior subordinated debentures (and related trust preferred securities (“TruPS”)), which are senior to our shares of preferred and common stock and have a preference on dividends), and will also depend on the Bank’s earnings, capital requirements, financial condition and other factors considered relevant by our board of directors. Dividends are payable on shares at the discretion of our board of directors, subject to the provisions of the Wisconsin Business Corporation Law, and any regulatory restrictions.

The stock market can be volatile, and fluctuations in our operating results and other factors could cause our stock price to decline.

The stock market has experienced, and may continue to experience, fluctuations that significantly impact the market prices of securities issued by many companies. Market fluctuations could adversely affect our stock price. These fluctuations have often been unrelated or disproportionate to the operating performance of particular companies. These broad market fluctuations, as well as general economic, systemic, political and market conditions, such as recessions, loss of investor confidence, interest rate changes, or international currency fluctuations, may negatively affect the market price of our common stock. Moreover, our operating results may fluctuate and vary from period to period due to the risk factors set forth herein. As a result, period-to-period comparisons should not be relied upon as an indication of future performance. Our stock price could fluctuate significantly in response to our quarterly or annual results, annual projections and the impact of these risk factors on our operating results or financial position.

We are subject to examinations and challenges by tax authorities that may be costly and time-consuming and may require expensive remedial action or other costs.

In the normal course of business, the Company and the Bank are routinely subject to examinations and challenges from federal and state tax authorities regarding the amount of taxes due in connection with investments that both entities have made and the businesses in which they have engaged. Federal and state taxing authorities have over the past few years become increasingly aggressive in challenging tax positions taken by financial institutions. These tax positions may relate to tax compliance, sales and use, franchise, gross receipts, payroll, property and income tax issues, including tax base, apportionment and tax credit planning. The challenges made by tax authorities may result in adjustments to the timing or amount of taxable income or deductions or the allocation of income among tax jurisdictions. If not resolved in our favor, such challenges could have an adverse effect on our financial condition and results of operations.

Holders

We had approximately 350 shareholders of record at March 15, 2018.  The number of shareholders does not reflect persons or entities that hold their stock in nominee or “street” name through various brokerage firms.

Dividends

We pay quarterly dividends on our common stock, and in 2017 our board of directors declared dividends totaling $0.24 per share.  On February 20, 2018, our Board of Directors declared a quarterly dividend totaling $0.07 per share for shareholders of record as of March 9, 2018.

Although we expect to pay dividends according to our dividend policy as of the date of this report, we may elect not to pay dividends. Any declarations of dividends will be at the discretion of our board of directors. In determining the amount of any future dividends, our board of directors will take into account: (i) our financial results; (ii) our available cash, as well as anticipated cash requirements (including debt servicing); (iii) our capital requirements and the capital requirements of our subsidiaries (including the Bank); (iv) contractual, legal, tax and regulatory restrictions on, and implications of, the payment of dividends by us to our shareholders or by the Bank to us; (v) general economic and business conditions; and (vi) any other factors that our board of directors may deem relevant. Therefore, there can be no assurance that we will pay any dividends to holders of our stock, or as to the amount of any such dividends.

Dividends we can declare and pay will depend primarily upon receipt of dividends from the Bank. See the section of this report entitled “Supervision and Regulation—Regulation and Supervision of the Bank—Dividends Payment” under Item 1, Business, of Part I. In addition, our ability to pay dividends currently or in the future may be materially limited by statutory or regulatory restrictions, and is subject to certain provisions of our TruPS.

(1) The tangible book value per share, return on average common shareholders’ equity, efficiency ratio and tangible common equity to tangible assets ratio are not recognized under generally accepted accounting principles of the United States (“GAAP”), and are therefore considered to be non-GAAP financial measures.  See below for reconciliations of the tangible book value per share, return on average common shareholders’ equity,  efficiency ratio and tangible common equity to tangible assets ratio to their most comparable GAAP measures.

(2) Net overhead ratio represents the difference between noninterest expense and noninterest income, divided by average assets.

(3) Non-performing assets consist of nonaccrual loans and other real estate owned.

Non-GAAP Financial Measures:

“Efficiency ratio” is defined as non-interest expenses, excluding gains and losses and write-downs of other real estate owned, divided by operating revenue, which is equal to net interest income plus non-interest income excluding gains and losses on sales of securities.  In our judgment, the adjustments made to non-interest expense allow investors to better asses our operating expenses in relation to our core operating revenue by removing the volatility that is associated with certain one-time items and other discrete items that are unrelated to our core business.

Return on average common shareholders’ equity is a non-GAAP financial measure calculated using non-GAAP based amounts.  The most directly comparable GAAP based measure is return on average shareholders’ equity.  We calculate return on average common shareholders’ equity by excluding the average preferred shareholders’ equity and the related dividends.  Management uses the return on average common shareholders’ equity in order to review our core operating results.  Management believes that this is a better measure of our performance than return on average shareholders’ equity.

Tangible book value per share and tangible common equity to tangible assets are non-GAAP financial measured calculated using non-GAAP based amounts.  We calculated tangible book value per share and tangible common equity to tangible assets by excluding intangible assets and preferred shareholders’ equity.  Management uses tangible book value per share and tangible common equity to tangible assets to review equity appreciation.  Management believes that this is better measure of equity appreciation than book value per share.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our consolidated financial statements and related notes thereto included in Item 8 of this Form 10-K. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause such differences are discussed in the sections titled “Forward-Looking Statements” and “Item 1A - Risk Factors.”

General

The following discussion and analysis presents our financial condition and results of operations on a consolidated basis. However, because we conduct all of our material business operations through the Bank, the discussion and analysis relates to activities primarily conducted at the Bank.

34

Executive Overview

We are the holding company for Investors Community Bank, which is headquartered in Manitowoc, Wisconsin. Our results of operations depend primarily on our net interest income. Net interest income is the difference between the interest income we earn on our interest-earning assets, such as loans, and the interest we pay on interest-bearing liabilities, such as deposits. We generate most of our revenue from interest on loans and investments and loan- and deposit-related fees. Our loan portfolio consists of a mix of agricultural, commercial real estate, commercial, residential real estate and installment and consumer loans. Our primary source of funding is deposits. Our largest expenses are interest on these deposits and salaries and related employee benefits. We measure our performance through various metrics, including our pre-tax net income, net interest margin, efficiency ratio, return on average assets, return on average common shareholders’ equity, earnings per share, and non-performing assets to total assets. We must also maintain appropriate regulatory leverage and risk-based capital ratios. The following table sets forth the key financial metrics we use to measure our performance.

	For the Year Ended December 31,
	2017			2016			2015			2014			2013
	(dollars in thousands)
Pre-tax income	$	18,216		$	17,177		$	17,493		$	12,894		$	11,152

Non-performing asset to total assets (2)		1.15	%		1.84	%		3.10	%		2.42	%		2.92	%

(1) This measure is not recognized under GAAP and is therefore considered to be a non-GAAP financial measure. See “Item 6 - Selected Financial Data” for a reconciliation of this measure to its most directly comparable GAAP measure.

(2) Non-performing assets consist of nonaccrual loans and other real estate owned.

Critical Accounting Policies and Estimates

Certain of our accounting policies are important to the portrayal of our financial condition, since they require management to make difficult, complex or subjective judgments, some of which may relate to matters that are inherently uncertain. Estimates associated with these policies are susceptible to material changes as a result of changes in facts and circumstances. Facts and circumstances which could affect these judgments include, but are not limited to, changes in interest rates, changes in the performance of the economy and changes in the financial condition of borrowers. Our significant accounting policies are discussed in detail in Note 1 to our Consolidated Financial Statements included in Item 8 of this Form 10-K. Those significant accounting policies that we consider to be most critical are described below. Our policies with respect to the methodology for the determination of the valuations of loans acquired in business combinations, goodwill, and core deposit intangible, the allowance for loan losses, OREO and fair value of financial instruments involve a degree of complexity and requires management to make difficult and subjective judgments which often require assumptions or estimates about highly uncertain matters. Changes in these judgments, assumptions or estimates could materially impact our results of operations. These critical policies and their application are reviewed with the board of directors annually and prior to any change in policy.

Business Combinations and Valuations of Loans Acquired in Business Combinations

We account for acquisitions under FASB Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. Assets acquired and liabilities assumed in a business combination are recorded at estimated fair value on their purchase date. As provided for under GAAP, management has up to 12 months following the date of acquisition to finalize any provisional fair values of acquired assets and assumed liabilities, where it was not possible to estimate the acquisition date fair value upon consummation. Management finalized the fair value of acquired assets and assumed liabilities within this 12-month period for the acquisition of Fox River Valley and management considers such values to be the fair values.

In particular, the valuation of acquired loans involves significant estimates, assumptions and judgments based on information available as of the acquisition date. Substantially all loans acquired in the transaction are evaluated either individually or in pools of loans with similar characteristics; since the estimated fair value of acquired loans includes a credit consideration, no carryover of any previously recorded allowance for loan losses is recorded at acquisition. A number of factors are considered in determining the estimated fair value of purchased loans including, among other things, the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, estimated holding periods, contractual interest rates compared to market interest rates, and net present value of cash flows expected to be received. 

35

In determining the fair value of acquired loans, management calculates a nonaccretable difference (the credit mark component of the acquired loans) and an accretable difference (the market rate or yield component of the acquired loans). The nonaccretable difference is the difference between the undiscounted contractually required payments and the undiscounted cash flows expected to be collected in accordance with management’s determination of the fair value. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows will result in a reversal of the provision for loan losses to the extent of prior charges and then an adjustment to accretable yield, and nonaccretable difference which would have a positive impact on interest income.

 The accretable yield on acquired loans is the difference between the expected cash flows and the initial investment in the acquired loans. The accretable yield is recognized into earnings using the effective yield method over the term of the loans. Management separately monitors the acquired loan portfolio and periodically reviews loans contained within this portfolio against the factors and assumptions used in determining the fair value.

In assessing the credit quality of the acquired loans, management determined that nine loans met the definition of purchased credit impaired as of the acquisition date of Fox River Valley, and applied the cost recovery method of accounting to those loans due to the uncertainty of the timing of expected cash flows.  This will generally result in the recognition of interest income on these impaired loans only when cash payments received from the borrower exceed the recorded net book value of the related loans.  

Goodwill and Core Deposit Intangible  

Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired and is included as an asset on the consolidated balance sheets. Goodwill is not amortized but is subject to impairment tests on at least an annual basis. Core deposit base premiums represent the value of the acquired customer core deposit bases and are included in as an asset on the consolidated balance sheets. The core deposit intangible has an estimated finite life, is amortized on an accelerated basis over a 66-month period, and is subject to periodic impairment evaluation.

Management will periodically review the carrying value of its long-lived and intangible assets to determine if any impairment has occurred or whether changes in circumstances have occurred that would require a revision to the remaining useful life, in which case an impairment charge would be recorded as an expense in the period of impairment. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. Goodwill was $5.0 million at December 31, 2017 and 2016.  There was no impairment charge to goodwill or core deposit intangible at December 31, 2017.  The net book value of core deposit intangible was $0.9 million and $1.4 million at December 31, 2017 and December 31, 2016, respectively.  Goodwill and core deposit intangible are included on the consolidated balance sheets.

Allowance for Loan Losses

The allowance for loan losses is established through a provision for loan losses charged to expense, which affects our earnings directly. Loans are charged against the allowance for loan losses when management believes that the collectability of all or some of the principal is unlikely. Subsequent recoveries are added to the allowance. The allowance is an amount that reflects management’s estimate of the level of probable incurred losses in the loan portfolio. Factors considered by management in determining the adequacy of the allowance include, but are not limited to, detailed reviews of individual loans, historical and current trends in loan charge-offs for the various portfolio segments evaluated, the level of the allowance in relation to total loans and to historical loss levels, levels and trends in non-performing and past due loans, volume of and migratory direction of adversely graded loans, external factors including regulatory requirements, reputation, and competition, and management’s assessment of economic conditions. Our board of directors reviews the recommendations of management regarding the appropriate level for the allowance for loan losses based upon these factors.

The provision for loan losses is the charge to operating earnings necessary to maintain an adequate allowance for loan losses. We have developed policies and procedures for evaluating the overall quality of our loan portfolio and the timely identification of problem credits. Management continuously reviews these policies and procedures and makes further improvements as needed. The adequacy of our allowance for loan losses and the effectiveness of our internal policies and procedures are also reviewed periodically by our regulators and our auditors and external loan review personnel. Our regulators may advise us to recognize additions to the allowance based upon their judgments about information available to them at the time of their examination. Such regulatory guidance is taken under consideration by management, and we may recognize additions to the allowance as a result.

We continually refine our methodology for determining the allowance for loan losses by comparing historical loss ratios utilized to actual experience and by classifying loans for analysis based on similar risk characteristics. Cash receipts for accruing loans are applied to principal and interest under the contractual terms of the loan agreements; however, cash receipts on impaired and nonaccrual loans for which the accrual of interest has been discontinued are applied to principal and interest income depending upon the overall risk of principal loss to us.

Other Real Estate Owned

Assets acquired through or in lieu of loan foreclosure are initially recorded at lower of cost or fair value less estimated costs to sell, establishing a new cost basis. Subsequent to foreclosure, independent valuations are performed annually 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 non-interest expense. Costs related to the development and improvement of other real estate owned is capitalized.

Fair Value of Financial Instruments

A significant portion of the Company’s assets are financial instruments carried at fair value. This includes securities available for sale and certain impaired loans. The majority of assets carried at fair value are based on either quoted market prices or market prices for similar instruments. For additional disclosures regarding the fair value of financial instruments, see Note 20. “Fair Value Measurements” to our consolidated financial statements.

JOBS Act Transition Period

The Jumpstart Our Business Startups (JOBS) Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of this extended transition period.

Merger Transaction

On May 13, 2016, the Company completed its acquisition of Fox River Valley and its wholly-owned bank subsidiary, The Business Bank, through the merger of Fox River Valley into a wholly-owned subsidiary of the Company (which subsequently dissolved) and the merger of The Business Bank into the Bank.  In connection with the merger, County acquired approximately $142 million in loans and $202 million of deposits.

The purpose of the acquisition was for strategic reasons management believes to be beneficial to the Company. The acquisition is consistent with its growth plans to expand into the markets of Appleton and Green Bay, Wisconsin and diversify its loan portfolio and agricultural concentration.  The Company believes it is well-positioned to achieve stronger financial performance and enhance shareholder value through synergies of the combined operations.  

Merger Consideration. In connection with the merger, County paid aggregate merger consideration of approximately $14.45 million in cash and 712,830 shares of the Company’s common stock.     

Board of Directors. Upon completion of the merger, the makeup of the board of directors expanded to include two new directors who previously sat on the board of Fox River Valley.

For additional information on this merger, see Note 2. “Acquisition” to our consolidated financial statements.

Comparison of Financial Condition at December 31, 2017, 2016, and 2015

Total Assets.  Total assets increased $154.4 million, or 12.4%, from $1.2 billion at December 31, 2016 to $1.4 billion at December 31, 2017.  The increase is primarily the result of loan growth of $118.5 million, an increase in loans held for sale of $5.4 million, and an increase in cash and due from banks of $24.1 million, between December 31, 2016 and December 31, 2017.  In addition, $5.5 million of additional bank owned life insurance policies were purchased during 2017.

Total assets increased $357.8 million, or 40.4%, from $884.9 million at December 31, 2015 to $1.2 billion at December 31, 2016.  The increase was primarily the result of the acquisition of Fox River Valley, which closed on May 13, 2016 and resulted in the addition of $229.7 million in assets. Including the impact of the assets acquired through the acquisition, loans increased $280.1 million, securities increased $40.2 million, and cash and due from banks increased $27.8 million, between December 31, 2015 and December 31, 2016.

Net Loans.  Total net loans increased by $117.9 million, or 11.6%, from $1.0 billion at December 31, 2016 to $1.1 billion at December 31, 2017.  The increase is attributed to a 9.9% increase in our agricultural portfolio, an 8.2% increase in our commercial real estate portfolio, and a 27.1% increase in our commercial portfolio.

Total net loans increased by $280.1 million, or 38.0%, from $737.8 million at December 31, 2015 to $1.0 billion at December 31, 2016.  The increase is attributed to a 25.0% increase in our agricultural portfolio, a 67.2% increase in our commercial real estate portfolio, a 73.0% increase in our commercial portfolio, and a 30.7% increase in our residential real estate portfolio, partially offset by a small decrease in our installment and consumer loans.

The majority of our loan participations and sales relate to agricultural customers. When customers request additional funding, generally for expansion of their operations, the existing loan participations are usually repurchased, with the consent of the participating institution, to allow for repackaging of the loans. This allows the new loans, including the additional funding, to be re-participated at a later time. The decision to re-participate a loan is dependent on many factors, including in-house lending limits and longer-term interest rate options provided to the borrower. As reflected by the balances of “Loans sold, net of repayments”, we decreased the amount of loans we participated in 2017 due to a change in the regulations of Farm Service Agency, which is a government program that guarantees many of the loans that we participate.  

Loan Servicing.  As part of our growth and risk management strategy, we have actively developed a loan participation and loan sales network. Our ability to sell loan participations and whole loans benefits us by freeing up capital and funding to lend to new customers as well as to increase non-interest income through the recognition of loan sale and servicing revenue. Because we continue to service these loans, we are able to maintain a relationship with the customer. Additionally, we receive a servicing fee that offsets some of the cost of administering the loan, while maintaining the customer relationship.

Securities. Our securities portfolio is predominately composed of municipal securities, investment grade mortgage-backed securities, and U.S. Government and agency securities. We classify substantially all of our securities as available for sale. We do not engage in active securities trading in carrying out our investment strategies.

Securities increased to $126.0 million at December 31, 2017 from $123.4 million at December 31, 2016, primarily as the result of additional security purchases of $53.1 million, which were partially offset by $21.1 million of security sales and $28.1 million of normal maturities and paydowns during 2017.

Securities increased to $123.4 million at December 31, 2016 from $83.3 million at December 31, 2015, primarily as the result of securities acquired through the acquisition of Fox River Valley, which totaled $49.5 million, which was partially offset by normal maturities and paydowns during 2016.

Deposits.  Deposits increased $132.6 million, or 13.6%, to $1.1 billion at December 31, 2017 from $977.5 million at December 31, 2016, primarily as a result of increased time and brokered deposits.  Deposits increased $305.3 million, or 45.4% to $977.5 million at December 31, 2016 from $672.2 million at December 31, 2015, of which $203.0 resulted from the acquisition of Fox River Valley. Interest-bearing deposits increased $257.5 million, while non-interest bearing deposits increased $47.7 million between December 31, 2015 and December 31, 2016.  

The changes in our deposit balance mix below reflect the impact of our loan growth outpacing our core deposit growth, resulting in an increase in brokered deposits of $89.0 million between December 31, 2016 and December 31, 2017, and an increase of $29.1 million between December 31, 2015 and December 31, 2016.  Our long-term strategy continues to be to increase core deposit balances through emphasizing our money market products and paying competitive rates, and we will remain focused on customer relationships in order to secure less volatile and less costly funding and reduce our reliance on brokered deposits.

Borrowings. The Bank had fixed rate advances outstanding from the FHLB-Chicago in the amount of $121.5 million, $107.9 million, and $66.4 million on December 31, 2017, December 31, 2016, and December 31, 2015, respectively. The terms of security agreements with the FHLB require the Bank to pledge collateral for such borrowings consisting of qualifying first mortgage loans, certain securities available for sale, and stock in the FHLB. We did not have overnight advances with the FHLB at December 31, 2017, 2016 or 2015.

As of December 31, 2017, 2016, and 2015, the Bank also had a $50.0 million line-of-credit available with the Federal Reserve Bank of Chicago.  Borrowings under this line of credit are limited by the amount of securities pledged by the Bank as collateral. Our available credit due to our pledged securities totaled $8.6 million, $11.2 million, and $15.8 million at December 31, 2017, 2016, and 2015, respectively.  We had no borrowings from the Federal Reserve Bank of Chicago as of December 31, 2017, 2016, or 2015.

We also have other borrowings as a result of sold loans that do not qualify for sale accounting. These agreements are recorded as financing transactions as we maintain effective control over the transferred loans. The dollar amount of the loans underlying the sale agreements continues to be carried in our loan portfolio, and the transfer is reported as a secured borrowing with pledge of collateral.

Subordinated Debentures. In September 2005 and June 2006, we formed two wholly owned subsidiary business trusts, County Bancorp Statutory Trust II (“Trust II”) and County Bancorp Statutory Trust III (“Trust III”), respectively, for the purpose of issuing capital securities which qualify as Tier 1 capital. Trust II issued at par $6.0 million of floating rate capital securities. The capital securities of Trust II are nonvoting, mandatorily redeemable in 2035, and are guaranteed by us. Trust III issued at par $6.0 million of floating rate capital securities. The capital securities of Trust III are nonvoting, mandatorily redeemable in 2036, and are also guaranteed by us.

We own all of the outstanding common securities of Trust II and Trust III. The trusts used the proceeds from the issuance of their capital securities to buy floating rate junior subordinated deferrable interest debentures (“debentures”) issued by the Company. These debentures are the trusts’ only assets, and interest payments from these debentures finance the distributions paid on the capital securities. These debentures are unsecured, rank junior, and are subordinate in the right of payment to all of our senior debt.

The capital securities of Trust II and Trust III have been structured to qualify as Tier 1 capital for regulatory purposes. However, the securities cannot be used to constitute more than 25% of the Company’s “core” Tier 1 capital according to regulatory requirements. We used the proceeds of the Trust II issue for general corporate purposes, and we used the proceeds of the Trust III issue to redeem the securities of County Bancorp Statutory Trust I.

As a result of the acquisition of Fox River Valley, we acquired a wholly owned subsidiary business trust, Fox River Valley Capital I Trust (“FRV Trust I”) which was formed in 2003 by Fox River Valley for the purpose of issuing capital securities which qualify as Tier I capital. The trust issued at par $3.5 million of floating rate securities. The securities are non-voting, mandatorily redeemable in 2033 and are guaranteed by us.

The capital securities of FRV Trust I have been structured to qualify as Tier I capital for regulatory purposes. However, the securities cannot be used to constitute more than 25% of the Company’s Tier I capital.  

Comparison of Operating Results for the Years Ended December 31, 2017, 2016, and 2015

Net Income.  Net income decreased $0.3 million, or 2.5%, for the year ended December 31, 2017 from the year ended December 31, 2016.  Net income for 2017 represented earnings per share of $1.52 (basic) and $1.49 (diluted).  The decrease was primarily due to a $1.1 million decrease in loan servicing fees and a $2.3 million increase in employee compensation and benefits for the year ended December 31, 2017 compared to the year ended December 31, 2016, which was almost entirely offset by a $3.6 million increase in net interest income between the same periods.  The year ended December 31, 2017 was also negatively impacted by $1.0 million of income tax expense related to the revaluation of the deferred tax asset as a result of the Tax Cuts and Jobs Act (the “Tax Act”) that was enacted into law on December 22, 2017.

Net income decreased $0.3 million, or 2.5%, for the year ended December 31, 2016 from the year ended December 31, 2015.  Net income for 2016 represents earnings per share of $1.65 (basic) and $1.61 (diluted).  The decrease was primarily due to expenses incurred relating to the acquisition, totaling $1.6 million, net of taxes, which were almost entirely offset by increased net interest

42

income. Net income, excluding merger related expenses, would have been $12.3 million, which represents an increase of $1.3 million, or 11.8% over 2015 net income. Adjusted earnings per share for 2016 would have been $1.91 (basic) and $1.86 (diluted).

The following table reconciles net income excluding merger related expenses (non-GAAP measure) to net income (GAAP):

	For the Year Ended December 31,
	2017		2016		2015
	(dollars in thousands)
Net income, excluding merger related expenses	$	10,425	$	12,313	$	10,974
Merger related expenses, net of taxes		—		1,619		—
Net income	$	10,425	$	10,694	$	10,974

Interest Income.  Total interest and dividend income increased by $7.5 million, or 16.4%, to $53.1 million for the year ended December 31, 2017 compared to the year ended December 31, 2016.  The increase is primarily the result of an increase in the average loan balance of $172.9 million due to organic loan growth.  The average yield on loans decreased 13 basis points for the year ended December 31, 2017 compared to the year ended December 31, 2016.  Interest on loans in 2016 included $1.9 million of accretion income relative to fair value adjustments on loans acquired; without the accreted income the average yield on loans would have declined 15 basis points for the year ended December 31, 2016 compared to the year ended December 31, 2017.  The effect of accreted income on the average yield was immaterial for the year ended December 31, 2017.

Total interest and dividend income increased $11.8 million, or 35.0%, to $45.6 million for the year ended December 31, 2016 compared to 2015.  The increase is primarily the result of an increase in the average loan balances of $233.6 million. Interest on loans in 2016 included $1.9 million of accretion income relative to fair value adjustments on loans acquired. The average yield on loans increased 2 basis points for the year ended December 31, 2016 compared to the year ended December 31, 2015. Without the accreted income the average yield on loans would have declined by 18 basis points for the year ended December 31, 2016 compared to the year ended December 31, 2015.

Interest Expense. Total interest expense for the year ended December 31, 2017 increased by $4.2 million, or 41.5%, to $14.2 million from the year ended December 31, 2016.  The increase is due primarily to a $160.5 million increase in average deposits and a $14.9 million increase in average FHLB advances.  Interest expense on interest-bearing accounts increased $3.6 million, or 44.2%, and interest expense on FHLB advances increased by $464 thousand, or 36.1% for the year 2017 compared to 2016. The average funding cost for interest-bearing liabilities for the year ended December 31, 2017 increased 21 basis points to 1.35% compared to 1.14% for the year ended December 31, 2016.  

Total interest expense for the year ended December 31, 2016 increased by $2.5 million, or 33.2% to $10.0 million from the year ended December 31, 2015, primarily due to the growth resulting from the acquisition. Total average deposits increased by $186.8 million, other borrowings decreased by $5.0 million, average FHLB advances increased by $68.4 million, and average subordinated debentures increased by $2.3 million. Interest expense on interest-bearing accounts increased $2.0 million, or 31.4%, and interest expense on FHLB advances increased by $678 thousand, or 111.8% for the year 2016 compared to 2015. Between the years 2016 and 2015, average rates for interest bearing deposits declined slightly for the year 2016, while the rate on FHLB advances declined by 23 basis points for the year 2016 compared to 2015.  

Income.  Net interest income for the year ended December 31, 2017 increased $3.3 million, or 9.3% to $38.9 million compared to the year ended December 31, 2016.  Net interest income for the year ended December 31, 2016 increased $9.3 million, or 35.5%, to $35.6 million from the same period in 2015.  

Our average interest-earning assets increased by $191.5 million, or 18.1%, to $1.3 billion for the year ending December 31, 2017 compared to the same period of 2016.  This is compared to averages of $1.1 billion and $780.4 million for the years ended December 31, 2016 and 2015, respectively.  Our net interest rate spread decreased to 2.89% for the year ended December 31, 2017 from 3.16% for the year ended December 31, 2016, and 3.13% for the year ended December 31, 2015. Our net interest margin decreased to 3.11% for the year ended December 31, 2017 from 3.35% for the year ended December 31, 2016 and 3.36% for the year ended December 31, 2015. The changes in our interest rate spread and net interest margin reflect yields of interest-earning assets decreasing while yields of interest-bearing liabilities increase.

Provision for Loan Losses.  Based on our analysis of the components of the allowance for loan losses described in “Allowance for Loan Losses” below, we recorded a provision for loan losses of $2.3 million for the year ended December 31, 2017, as the result of continued growth in the loan portfolio and charge-offs taken during the year compared to a provision for loan losses of $3.0 million for the year ended December 31, 2016, and a credit provision for loan losses of $1.0 million for the year ended December

31, 2015. For the year ended December 31, 2017, we charged-off $1.9 million in loans, compared to $1.7 million the year ended December 31, 2016, and $1.9 million for the year ended December 31, 2015, and recoveries for the same periods were $0.2 million, $1.0 million, and $2.7 million, respectively. Of the $1.0 million in loan recoveries for the year ended December 31, 2016, $0.9 million was from a single customer, while for the year ended December 31, 2015, $1.6 million of loan recoveries were from a single customer. The total allowance for loan losses was $13.2 million, or 1.15%, of total loans, and $12.6 million, or 1.23% of total loans, at December 31, 2017 and 2016, respectively. The total allowance for loan losses was $10.4 million, or 1.39% of total loans, as of December 31, 2015.  Total non-performing loans, excluding performing troubled debt restructurings, were $11.6 million at December 31, 2017.  This was an $8.5 million decrease from December 31, 2016. The allowance for loan losses reflects the estimate we believe to be appropriate to cover probable incurred losses inherent in the loan portfolio at December 31, 2017.

Non-Interest Income.  Non-interest income decreased by $1.0 million, or 12.2%, to $7.7 million for the year ended December 31, 2017 compared to $8.7 million for the same period of 2016.  Non-interest income increased $1.0 million, or 13.4%, to $8.7 million for the year ended December 31, 2016 compared to the year ended December 31, 2015, which reported non-interest income of $7.7 million.  The primary factor contributing to the annual fluctuation in non-interest income is the Bank’s volume and activity in loan servicing fees and loan servicing rights income. For the three-year period ended December 31, 2017 loan servicing fees increased $0.2 million, from $5.3 million in 2015 to $6.6 million in 2016 to $5.5 million in 2017. The decrease from 2016 to 2017 was the result of a Farm Service Agency procedural change that has delayed our secondary market sale activity.

Non-Interest Expense.  Non-interest expense increased $1.8 million, or 7.6%, to $26.0 million for the year ended December 31, 2017, compared $24.1 million for the same period of 2016 as the result of an increase in employee compensation and benefits of $2.3 million.  This is attributed to an increase of nine full-time equivelant employees, or 6.7%, to 144 for the year-ended December 31, 2017, and a 21.1% increase in benefit costs from the year December 31, 2016.  The increase to employee compensation was partially offset by the one-time merger related expenses that were incurred in 2016.  During the fourth quarter of 2017, $0.4 million of business development expenses were accelerated from future periods to maximize the tax advantage of the higher corporate tax rate of 2017.

For the year ended December 31, 2016, non-interest expense increased $6.7 million, or 38.3%, to $24.1 million from $17.5 million for the year ended December 31, 2015.  The largest component of the increase was $2.6 million of expenses directly related to the acquisition and an additional $2.1 million of the increase reflected higher operating expenses associated with the growth in the organization resulting from the acquisition. As a result of the acquisition, the Company operates two additional full-service banking facilities, which resulted in an increase in full-time equivalent employees to 135 at December 31, 2016 from 102 at December 31, 2015, an increase of 32.4% This contributed to employee compensation and benefits increasing $2.3 million, or 21.7%, between 2015 and 2016. Other significant increases included information processing expenses of $1.7 million and professional fees of $0.5 million, which were primarily related to the merger.

Income Taxes. Income tax expense for the year ended December 31, 2017 was $7.8 million compared to $6.5 million for each of the years ended December 31, 2016 and 2015, respectively.  The effective tax rates as a percent of pre-tax income were approximately 43%, 38%, and 37%, for the years ended December 31, 2017, 2016, and 2015, respectively.  The increase in income tax expense and the effective tax rate for the year ended December 31, 2017 was due to a $1.0 million, or $0.15 per diluted share, reduction in the value or our net deferred tax asset which was recorded as additional income tax expense as a result of the Tax Act that was enacted late in the 4^th quarter of 2017.  

Analysis of Net Interest Income

Net interest income represents the difference between income we earn on our interest-earning assets and the expense we pay on interest-bearing liabilities. Net interest income depends on the volume of interest-earning assets and interest-bearing liabilities and the interest rates earned on such assets and paid on such liabilities.

Rate/Volume Analysis. The following table presents the effects of changing rates and volumes on our net interest income for the periods indicated. The rate column shows the effects attributable to changes in rate (changes in rate multiplied by prior volume). The volume column shows the effects attributable to changes in volume (changes in volume multiplied by prior rate). The net column represents the sum of the prior columns. For purposes of this table, changes attributable to both rate and volume, which cannot be segregated, have been allocated proportionately based on the changes due to rate and the changes due to volume.

Risk Management

Overview. Managing risk is an essential part of successfully managing a financial institution. Among our most prominent risk exposures are market risk, credit risk, interest rate risk and liquidity risk. Credit risk is the risk of not collecting the interest and/or the principal balance of a loan or security when it is due. Interest rate risk is the potential reduction of net interest income or the reduction in the value of assets and liabilities as a result of changes in interest rates. Market risk refers to potential losses arising from changes in interest rates, commodity prices, real estate prices and/or other relevant market rates or prices. Liquidity risk is the possible inability to fund obligations to depositors, lenders or borrowers when due. Other risks that we face are operational risk, cyber risk, and reputation risk. Operational risks include risks related to fraud, regulatory compliance, processing errors, technology, and disaster recovery. Cyber risk is the risk of technological intrusion resulting in loss of customer information, loss of data, denial of service attacks, and cyber-theft. Reputation risk is the risk that negative publicity or press, whether true or not, could cause a decline in our customer base or revenue.

Credit Risk Management. Our strategy for credit risk management focuses on having a layered approach to risk involving risk-taking, risk monitoring, and risk mitigation. In our target markets, we field an experienced lending staff supported by a centralized, robust risk management infrastructure working under well-defined credit policies and rigorous underwriting criteria. We have developed portfolio strategies and controls that are conducive to the development of a diversified loan portfolio including a variety of exposure control limits on different portfolio segments and have established an internal lending limit that is substantially below our legal lending limit. Regular total portfolio and loan level monitoring ensures timely risk recognition, provides early warning of potential problems and allows prompt attention to potential problem loans. This strategy emphasizes generally conservative loan-to-value ratios and full recourse to guarantors with substantial net worth on credit exposures. In addition to our portfolio monitoring practices, we have a comprehensive loan review system using both internal and external resources to review at least 30% of portfolio exposure annually. Formal management quarterly problem loan reviews include assessment of risk ratings and loan collateral valuation in order to identify impaired loans.

The Bank takes a proactive approach to managing problem loans. Delinquent loans greater than 15 days are reviewed by the management team weekly. When a borrower fails to make a required loan payment, management takes a number of steps to have the borrower cure the delinquency and restore the loan to a current status. Bankers make the initial contact with the borrower when the loan becomes 15 days past due. If payment is not then received by the 30th day of delinquency, additional points of contact are generally made, the loan risk rating is reassessed, and a plan of collection is identified and pursued for each individual loan. The loan relationship may be downgraded and transferred to a special assets officer, depending on the prospects for the borrower bringing the loan current, the financial strength and commitment of any guarantors, the type and value of the collateral securing the loan and other factors. Collection efforts may lead to a demand of repayments, the initiation of litigation and/or foreclosure on collateral securing the

46

loan. If a foreclosure action is instituted and the loan is not brought current, paid in full, or refinanced before the foreclosure sale, the assets or real property securing the loan generally are sold by the Bank in a commercially reasonable manner. While we develop loan workout arrangements for most problem loans, we also consider the sale of the non-performing loans. Management regularly informs the board of directors of the amount and status of delinquent loans, all loans rated special mention or worse, all nonaccrual loans, all troubled debt restructures, and all OREO. When a credit is downgraded to “special mention” and/or “substandard,” it is generally transferred to a special assets officer.

Non-Performing Assets. We consider foreclosed assets and loans that are maintained on a nonaccrual basis to be non-performing assets. Loans are generally placed on nonaccrual status when collectability is judged to be uncertain or payments have become 90 days or more past due. On loans where the full collection of principal or interest payments is not probable, the accrual of interest income ceases and any already accrued interest is reversed. Interest income is not accrued on such loans until the borrower’s financial condition and payment record demonstrate an ability to service the debt. Payments received on a nonaccrual loan are first applied to the outstanding principal balance when collectability of principal is in doubt.

Real estate that we acquire as a result of foreclosure or by deed-in-lieu of foreclosure is classified as OREO until it is sold. Assets acquired through or in lieu of loan foreclosure are initially recorded at fair value less costs to sell. Upon acquiring a property, the Bank engages an independent third party realtor to assist in marketing and selling the property. Management reviews all OREO on a quarterly basis and makes adjustments to listing prices and marketing strategies as deemed appropriate. On an annual basis all OREO properties are re-appraised by independent third party appraisers. Any holding costs and declines in fair value after acquisition of the property result in charges against income.

Troubled debt restructurings occur when we grant borrowers concessions that we would not otherwise grant but for economic or legal reasons pertaining to the borrower’s financial difficulties. Generally, this occurs when the cash flows of the borrower are insufficient to service the loan under its original terms. We may modify the terms of a loan as a troubled debt restructuring by reducing the loan’s stated interest rate, extending the loan’s maturity or otherwise restructuring the loan terms to enable payment. We may consider permanently reducing the recorded investment in the loan or structuring a non-accruing secondary note in a troubled debt restructuring as well but we generally do not make such concessions. Modifications involving a reduction of the stated interest rate of loans are typically for periods ranging from six months to one year. These modifications are made only when there is a reasonable and attainable workout plan that has been agreed to by the borrower and that is in our best interests. Loans classified as troubled debt restructurings are rated “substandard” by the Bank. Once the borrower has demonstrated sustained performance with the modified terms, the loan may be removed from non-performing status. Any loans categorized as troubled debt restructurings will continue to retain that designation through the life of the loan.

Volatility in milk prices is a normal aspect of the dairy business.  In 2017, the Wisconsin dairy economy continued recovering from a 21 month slump in milk prices that ended in May 2016 with a Class III milk price low of $12.76 cwt.  In June 2016, the Class III prices started to stabilize and averaged a price of $16.08 cwt for the 19 month period ending December 31, 2017.  The 2018 Class III milk prices once again have declined with February 2018 being $13.40 cwt.  The amount a farmer actually receives is increased by the amount of fat, protein and other valuable components of the milk sold.  As milk prices ebb and flow, certain farmers may be adversely impacted by sustained periods of lower prices.  Since its formation in 1997, the Bank has worked with distressed customers to help them pull through the downturn.  However, until the customers return to profitability, there will likely be an increase in troubled debt restructuring and non-performing loans.  We believe that due to the growing market for dairy products, the collateral value of farm real estate will remain solid.  According to a 2017 report, the Wisconsin Department of Agriculture, Trade and Consumer Protection reported the value of Wisconsin farm real estate increased by 1.41% during 2016.

(1) 2017 and 2016 include $0.4 million of bank property transferred from premises and equipment which is not considered a non-performing asset.

(2) Non-performing assets are defined as nonaccrual loans plus OREO.

(3) Loans are presented before allowance for loan losses and do not include deferred loan origination costs (fees).

Interest income that would have been recorded for the years ended December 31, 2017, 2016, and 2015, had nonaccrual loans been current according to their original terms, amounted to $1.9 million, $1.5 million, and $1.7 million, respectively. No income related to nonaccrual loans was included in interest income for the years ended December 31, 2017, 2016, and 2015.

Total nonaccrual loans decreased by $8.5 million to $11.6 million at December 31, 2017.  Total nonaccrual loans decreased from December 31, 2015 to December 31, 2016 by $4.5 million to $20.1 million.  The decrease in both years was primarily due to collection activities, loan payoffs, and the completion of foreclosures and transfer of properties into OREO.  

The Bank is actively managing its OREO portfolio.  As of December 31, 2017, OREO totaled $5.0 million compared to $3.2 million at December 31, 2016, and $2.9 million at December 31, 2015. The increase in OREO at December 31, 2017 compared to December 31, 2016, was the result of transferring $5.1 million of properties to OREO, offset by sales of $3.3 million.  We expect the balance of the OREO in our portfolio and the related expenses to decline as we continue to sell properties.

Special Mention and Classified Loans. Federal regulations require us to review and classify loans on a regular basis. There are four classifications for problem loans: special mention, substandard, doubtful and loss. We categorize loans into these risk categories based on relevant information about the ability of borrowers and, if appropriate, guarantors to service their debts, and the quality and projected realizable value of collateral. We analyze loans through quarterly asset quality reviews based on observable risk criteria such as overdrafts, late payments, financial performance and collateral valuations.

We have two categories of “Substandard loans.”  “Substandard – Performing” credits generally have a well-defined weakness; however, collateral coverage is adequate, the loans are not considered impaired, payments are being made, and the loans are on accrual status.  “Substandard – Impaired” credits are inadequately protected by the current sound net worth and paying capacity of the obligor or the collateral pledged. As such they have a well-defined weakness that jeopardizes the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. “Doubtful loans” have all the weaknesses inherent in substandard loans with the additional characteristic that the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions and values questionable, and there is a high possibility of loss. A loan classified as “loss” is considered uncollectible and of such little value that continuance as a loan of the institution is not warranted. When management classifies a loan as

48

substandard or doubtful, a specific allowance for probable and reasonably estimable loan losses is established. If management classifies a loan as loss, an amount equal to 100% of the portion of the loan classified as loss is charged to the allowance for loan losses.

The following table shows the aggregate amounts of our substandard and special mention loans.

Allowance for Loan Losses

The allowance for loan losses is a valuation allowance for probable incurred credit losses inherent in the loan portfolio. This estimate includes losses associated with specifically identified loans, as well as estimated probable credit losses inherent in the remainder of the loan portfolio. Loan losses are charged against the allowance when, in our judgment, the uncollectability of all or a portion of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Reductions to the allowance occur as loans are charged off. We estimate the required amount of the allowance using a number of factors, including past loan loss experience, the nature of the portfolio, economic conditions, information about specific borrower situations, and estimated collateral values. We evaluate the adequacy of the allowance for loan losses on a quarterly basis, although we may increase the frequency of our reviews as necessary. When additional allowance for loan loss is necessary, a provision for loan losses is charged to earnings.

Our methodology for assessing the sufficiency of the allowance for loan losses consists three components: (a) a general component related to performing or “pass rated” credits (the significant majority of the loan portfolio), (b) a nonimpairment component, and (c) a specific component relating to loans that are individually classified as impaired. Although we determine the amount of each element of the allowance separately, the entire allowance for loan losses is available for the entire portfolio.

As disclosed in the notes to the financial statements, our allowance for loan losses is comprised primarily of general reserves of $11.8 million with a limited amount of specific reserves totaling $1.4 million at December 31, 2017. This compares to $11.3 million with a limited amount of specific reserves totaling $1.3 million at December 31, 2016 and $8.1 million of general reserves and $2.3 million of specific reserves at December 31, 2015.

General Component. The general component of the allowance for loan losses relates to loans that are not determined to be impaired. Management determines the appropriate loss factor for each segment of loans with similar risk characteristics within the portfolio based on that segment’s loss experience and several other quantitative, qualitative and economic factors relevant to each segment. While loan segments generally represent groups of loans with similar risk characteristics, we may include loans categorized by loan grade, or any other characteristic that causes a loan’s risk profile to be similar to a group of loans. We consider estimated credit losses associated with each segment of our portfolio to differ from purely historical loss experience due to qualitative factors including changes in lending policies and procedures and changes in the nature and volume of the loan portfolio; quantitative factors including changes in the volume and severity of past due, nonaccrual, and adversely graded loans, changes in concentrations of credit, and changes in the value of underlying collateral for collateral dependent loans; and economic factors including changes in economic or business conditions and the effect of competition, legal and regulatory requirements on estimated credit losses.  The historical charge-off data is updated on a rolling quarterly basis, with the oldest quarter’s charge-off data being replaced with the most recent quarter’s charge-off data.  We typically give more weight to the more recent charge-off data for each specific type of loan, as we believe that is more indicative of current trends.  Our quantitative, qualitative, and economic factors are reviewed on a quarterly basis for each loan segment and our historical loss experience is reviewed quarterly to ensure that our analysis is reflective of current conditions in our loan portfolio and economy.

Non-Impaired Component. Loans that have been downgraded to special mention or substandard-performing, but are not currently impaired, are considered to have a higher inherent of risk of loss than pass rated loans. Management judgment is needed to estimate the additional risk of loss for these types of loans. Risk allocations on non-impaired special mention and substandard-performing loans reflect management’s assessment of the increased risk of loss associated with adversely graded loans. The allocated reserve for these loans is based upon management’s assessment of loss history and risk migration analysis. Additionally, in determining the allocation, management considers the credit attributes of individual loans, including loan to value ratios, past due status, strength and willingness of the guarantors, and other relevant attributes generally found in these groups of loans.

51

Specific Component. The specific component of the allowance for loan losses relates to loans that are individually evaluated and determined to be impaired. The allowance for each impaired loan is determined by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the market price reasonably obtainable for the loans or, if the loan is collateral dependent, by the fair value of the collateral less estimated costs to sell.  Collateral valuations are supported by current appraisals, which are discounted by us based upon a liquidation scenario.  Impairment for other types of loans is measured using the fair value of the collateral less estimated costs to sell. We identify a loan as impaired when, based upon current information and events, it is probable that we will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. We consider a number of factors in determining impairment, including payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower.

Discussion of Allowance for Loan Losses. At December 31, 2017, our allowance for loan losses was $13.2 million, or 1.2% of loans and 114.6% of nonaccrual loans.  At December 31, 2016, our allowance for loan losses was $12.6 million, or 1.2% of loans and 62.9% of nonaccrual loans, and at December 31, 2015, our allowance for loan losses was $10.4 million, or 1.4% of loans and 42.3% of nonaccrual loans.  Nonaccrual loans at December 31, 2017 were $11.6 million, or 1.0% of loans, compared to $20.1 million, or 2.0% of loans at December 31, 2016, and $24.6 million, or 3.3% of loans at December 31, 2015.

Between December 31, 2016 and December 31, 2017, the Bank’s OREO portfolio increased from $3.2 million to $5.0 million, an increase of $1.8 million, or 57.0%. The increase is primarily due to the foreclosure of four properties totaling $5.1 million, $0.4 million transferred from premises and equipment, which was offset in part by $3.3 million of property sales.    

Many factors are evaluated in our analysis of the allowance for loan loss, including milk price and unemployment rates, economic and business conditions and our most recent historical loss experience. Notwithstanding the improvement in the quantitative, qualitative and economic factors in recent years, we anticipate we will resume making provisions to the allowance for loan losses to support growth in the loan portfolio in the near future, as circumstances warrant.

The allowance for loan losses is maintained at a level that represents management’s best estimate of probable incurred losses in the loan portfolio at the balance sheet date. However, there can be no assurance that the allowance for loan losses will be adequate to cover losses which may be realized in the future or that additional provisions for loan losses will not be required.

Liquidity Management and Capital Resources

Liquidity is the ability to meet current and future financial obligations of a short-term and long-term nature. Our primary sources of funds consist of deposit inflows, loan repayments, maturities and sales of securities and borrowings from the FHLB. While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows, calls of investment securities and borrowed funds and prepayments on loans are greatly influenced by general interest rates, economic conditions and competition.  At December 31, 2017, the Bank had fixed rate advances outstanding with FHLB of $121.5 million and no borrowings outstanding at the Federal Reserve Bank of Chicago.   The Bank had unused collateral of $40.5 million with FHLB and a $50 million line-of-credit available with the Federal Reserve Bank of Chicago at December 31, 2017.

Management adjusts our investments in liquid assets based upon an assessment of (1) expected loan demand, (2) expected deposit flows, (3) yields available on interest-earning deposits and securities, (4) the objectives of our interest-rate risk and investment policies and (5) the risk tolerance of management and our board of directors.

Our cash flows are composed of three primary classifications: cash flows from operating activities, investing activities, and financing activities. Net cash provided by operating activities was $11.3 million, $25.6 million, and $7.1 million, for the years ended December 31, 2017, 2016, and 2015, respectively. Net cash used in investing activities, which consists primarily of purchases of and proceeds from the sale, maturities/calls, and principal repayments of securities available for sale, as well as loan purchases, sales and originations, net of repayments was $131.5 million, $124.3 million, and $103.7 million, for the years ended December 31, 2017, 2016, and 2015, respectively. Net cash provided by financing activities, consisting primarily of the activity in deposit accounts and FHLB and Federal Discount advances, was $144.3 million, $126.5 million, and $101.1 million, for the years ended December 31, 2017, 2016, and 2015, respectively.

At December 31, 2017, the Bank exceeded all of its regulatory capital requirements to be considered well-capitalized with a Tier 1 leverage capital of $147.6 million, or 10.76% of average total assets, which is above the required level of $68.6 million, or 5.0% of average total assets, and total risk-based capital of $161.4 million, or 12.79% of risk-weighted assets, which is above the required level of $126.2 million, or 10.0% of risk-weighted assets. The Bank had Tier 1 risk-based capital of $147.6 million, or 11.69% of risk-weighted assets, which is above the required level to be considered well-capitalized of $100.9 million, or 8.0% of risk-weighted assets, and Tier 1 common equity of $147.6 million, or 11.69% of risk-weighted assets, which is above the required level to be considered well-capitalized of $82.0 million, or 6.5% of risk-weighted assets at December 31, 2017.  For a discussion of certain other sources of liquidity, please see “Comparison of Financial Condition at December 31, 2017, 2016 and 2015—Borrowings.”

54

At the holding company level, our primary sources of liquidity are dividends from the Bank, investment income and net proceeds from investment sales, borrowings and capital offerings. The main uses of liquidity are the payment of interest to holders of our junior subordinated debentures and interest and payment of dividends to preferred shareholders and common shareholders. There are certain restrictions on the payment of dividends by the Bank to us, which are described in the section captioned “Item I – Business - Supervision and Regulation—Regulation and Supervision of the Bank—Dividend Payments.” At December 31, 2017, there were $85.9 million of retained earnings available for the payment of dividends by the Bank to us. The Bank paid us $1.1 million and $1.2 million in dividends during the year ended December 31, 2017 and 2016, respectively.

Off-Balance Sheet Arrangements

In the normal course of operations, we engage in a variety of financial transactions that, in accordance with GAAP, are not recorded in our financial statements. These transactions involve, to varying degrees, elements of credit, interest rate and liquidity risk. Such transactions are used primarily to manage customers’ requests for funding and take the form of commitments to extend credit.

Commitments to extend credit are agreements to lend funds 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. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if deemed necessary by the Bank, 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 to existing customers. These lines of credit are usually collateralized and contain a specified maturity date and may not be drawn upon to the total extent to which the Bank is committed.

Standby letters of credit are conditional commitments issued by the Bank to guarantee the payment or the performance of a Bank customer to a third party. Both standby and performance letters of credit are generally issued for terms of one to four years. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank generally holds collateral supporting these commitments

At December 31, 2017, we had outstanding commitments to originate loans and unadvanced funds on loans of $235.8 million. We anticipate that we will have sufficient funds available to meet our current loan origination commitments. Certificates of deposit that are scheduled to mature in one year or less from December 31, 2017 totaled $267.6 million. If a substantial portion of these deposits are not retained, we may utilize FHLB advances, wholesale deposits, or raise interest rates on deposits to attract new accounts, which may result in higher levels of interest expense. At December 31, 2017, we had no irrevocable and stand-by-letters of credit from the FHLB.

For the years ended December 31, 2017, 2016, and 2015, we did not engage in any off-balance sheet transactions reasonably likely to have a material effect on our financial condition, results of operations or cash flows.

The following table summarizes significant contractual obligations and other commitments as of December 31, 2017:

Effect of Inflation and Changing Prices

The consolidated financial statements and related financial data presented in this Form 10-K have been prepared according to GAAP, which requires the measurement of financial position and operating results in terms of historical dollars without considering

55

the change in the relative purchasing power of money over time due to inflation. The primary impact of inflation on our operations is reflected in increased operating costs and the effect that general inflation may have on both short-term and long-term interest rates. Virtually all the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates generally have a more significant impact on a financial institution’s performance than do general levels of inflation. Although inflation expectations do affect interest rates, interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

General. Market risk refers to potential losses arising from changes in interest rates, commodity prices, such as milk prices, and/or other relevant market rates or prices. We are exposed to market risk as a result of our banking activities. Our market risk is comprised primarily of interest rate risk. As a financial institution, the majority of our assets and liabilities are sensitive to changes in interest rates. Therefore, a principal part of our operations is to manage interest rate risk and limit our exposure to changes in market interest rates. We manage the interest rate sensitivity of our interest-bearing liabilities and interest-earning assets in an effort to minimize the adverse effects of changes in the interest rate environment.

A major source of interest rate risk is a difference in the repricing of assets and liabilities. First, there are differences in the timing of rate changes reflecting the maturity and/or repricing of assets and liabilities. For example, the rate earned on a commercial real estate loan may be fixed for 10 years, while the rate paid on a certificate of deposit may be fixed only for a few months. Due to these timing differences, net interest income is sensitive to changes in the level and shape of the yield curve. Second, there are differences in the drivers of rate changes of various assets and liabilities known as basis risk. For example, commercial loans may reprice based on one-month LIBOR or prime, while the rate paid on retail money market demand accounts may be only loosely correlated with LIBOR and depend on competitive demand for funds. Due to these basis differences, net interest income is sensitive to changes in spreads between certain indices or repricing rates.

Another important source of interest rate risk relates to the potential exercise of explicit or embedded options for prepayment or withdrawal. For example, most residential real estate loans can be prepaid without penalty, and most consumer deposits can be withdrawn without penalty. The exercise of such options by customers can exacerbate the timing differences discussed above.

Deposit accounts typically react more quickly to changes in market interest rates than loans because of the shorter maturities of deposits. However, given the asset sensitive nature of our balance sheet, a decrease in interest rates may adversely affect our earnings while increases in interest rates may beneficially affect our earnings. To reduce the potential volatility of our earnings, we have sought to improve the match between asset and liability maturities and rates, while maintaining an acceptable interest rate spread. Our strategy for managing interest rate risk emphasizes adjustable-rate loans for retention in our loan portfolio, promoting core deposit products and time deposits, adjusting the maturities of borrowings and adjusting the investment portfolio mix and duration.

We have an asset/liability committee, which includes members of management, to communicate, coordinate and control all aspects involving asset-liability management. The committee establishes and monitors the volume, maturities, pricing and mix of assets and funding sources with the objective of managing assets and funding sources to provide results that are consistent with liquidity, growth, risk limits and profitability goals.

Our goal is to manage asset and liability positions to moderate the effects of interest rate fluctuations on net interest income and net income and control exposure to interest rate risk within policy limits approved by our board of directors. These limits and guidelines reflect our tolerance for interest rate risk over both short-term and long-term horizons. We analyze our sensitivity to changes in interest rates through our net interest income simulation model. Exposures are reported on a monthly basis to the asset and liability committee and at meetings of our board of directors.

Net Interest Income Simulation Analysis. Net interest income is the difference between the interest income we earn on our interest-earning assets, such as loans and securities, and the interest we pay on our interest-bearing liabilities, such as deposits and borrowings.

Income simulation is the primary tool for measuring the interest rate risk inherent in our balance sheet at a given point in time by showing the effect on net interest income, over specified time horizons, under a range of interest rate shock scenarios. These simulations take into account repricing, maturity and prepayment characteristics of individual products. We estimate what our net interest income would be for a one- and two-year horizon based on current interest rates. We then calculate what the net interest income would be for the same period under different interest rate assumptions.

These estimates require us to make certain assumptions, including loan and mortgage-related investment prepayment speeds, reinvestment rates, and deposit maturities and decay rates. These assumptions are inherently uncertain, and, as a result, we cannot precisely predict the impact of changes in interest rates on our net interest income. Although the net interest income table below

56

provides an indication of our interest rate risk exposure at a particular point in time, such estimates are not intended to, and do not, provide a precise forecast of the effect of changes in market interest rates on our net interest income and will differ from actual results

The following table shows the estimated impact on net interest income for the one- and two-year periods beginning December 31, 2017 resulting from potential changes in interest rates. The net interest income simulation analyses assume a static balance sheet and do not include possible future actions that management might undertake to mitigate this risk.

Rate Shift	Net Interest Income Year 1 Forecast		Year 1 Change from Base			Net Interest Income Year 2 Forecast		Year 2 Change from Base
	(dollars in thousands)					(dollars in thousands)
+400 bps	$	49,969		11.29	%	$	108,049		15.84	%
+200 bps		47,457		5.69	%		100,620		7.88	%
+100 bps		46,199		2.89	%		96,948		3.94	%
Base		44,901		0.00	%		93,272		0.00	%
-100 bps		42,399		(5.57	)%		87,119		(6.60	)%
-200 bps		37,668		(16.11	)%		74,760		(19.85	)%

As of December 31, 2017, net interest income simulation indicated that our exposure to changing interest rates was within our internal policy guidelines. As the table illustrates, our balance sheet is asset-sensitive over a one and two year time horizon and net interest income would increase as interest rates increase. It should be noted that the magnitude of any possible increase in interest rates is constrained by the low absolute starting levels of rates. While immediate, proportional and severe shifts in interest rates upward were used as part of this analysis, we believe that any actual shift in interest rates would likely be more gradual and would therefore have a more modest impact.

Depending on the relationship between long-term and short-term interest rates, market conditions and consumer preference, we may place greater emphasis on maximizing our net interest margin than on strictly matching the interest rate sensitivity of our assets and liabilities. We believe that our level of interest rate risk is acceptable using this approach.

Economic Value of Equity Analysis. We also analyze the sensitivity of our financial condition to changes in interest rates through our economic value of equity model. This analysis measures the difference between predicted changes in the present value of our assets and predicted changes in the present value of our liabilities assuming various changes in current interest rates. As with the net interest income simulation model, the estimates of changes in the economic value of our equity require certain assumptions to be made. These assumptions include loan and mortgage-related investment prepayment speeds, reinvestment rates, and deposit maturities and decay rates. These assumptions are inherently uncertain, and, as a result, we cannot precisely predict the impact of changes in interest rates on the economic value of our equity. Although our economic value of equity analysis provides an indication of our interest rate risk exposure at a particular point in time, such estimates are not intended to, and do not, provide a precise forecast of the effect of changes in market interest rates on the economic value of our equity and will differ from actual results.

Our economic value of equity analysis as of December 31, 2017 is set forth below. The impact on our economic value of equity under all scenarios referenced in the table below are within policy guidelines.

Rate Shift (1)	Economic Value of Equity		% Change In
	(dollars in thousands)
+400 bps	$	121,680		(17.29	)%
+200 bps		133,106		(9.53	)%
+100 bps		139,759		(5.00	)%
Base		147,119		0.00	%
-100 bps		150,276		2.15	%
-200 bps		148,185		0.72	%

(1) The calculated changes assume an immediate and proportional shock of the static yield curve.

COUNTY BANCORP, INC AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2017, 2016, and 2015

NOTE 1—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting and reporting policies of County Bancorp, Inc. and its subsidiaries conform to accounting principles generally accepted in the United States of America and to general practice within the banking industry. The following is a description of the more significant of those policies.

Nature of Business and Significant Concentrations of Credit Risk

The Company is the sole shareholder of Investors Community Bank. The Bank is the sole member of Investors Insurance Services, LLC and ABS 1, LLC, which are both Wisconsin limited liability companies. The Company commenced operations in May of 1996; the Bank commenced operations in March of 1997. ICB Investment Corp. commenced operations in 2001. In July of 2010, the Bank formed Investors Insurance Services, LLC for the sole purpose of protecting the Bank from liability risk when selling crop insurance. Selling crop insurance had historically been a business function performed within the Bank. In September of 2011, the Bank formed ABS 1, LLC, for the sole purpose of holding real estate and personal property for sale which was obtained through repossession.  In November 2015, the Company formed County Acquisition LLC for the sole purpose of acquiring Fox River Valley Bancorp, Inc., and it was subsequently dissolved in May of 2016 after the Fox River Valley acquisition was completed.  In August of 2017, the Bank dissolved  ICB Investment Corp., which was a wholly-owned Nevada subsidiary, and distributed its assets to the Bank.

The Bank provides a full range of banking and related financial services, which include real estate lending, business services, and agricultural finance, to individual and corporate customers primarily located within the state of Wisconsin. The Bank’s primary source of revenue is providing loans to customers, who are predominantly engaged in dairy farming and commercial activities. Its primary deposit products are savings and term certificate accounts. The Bank is subject to competition from other financial institutions and is regulated by federal and state banking agencies and undergoes periodic examinations by those agencies.

The Company has no other significant activities other than ownership of the Bank. Note 4 discusses the types of securities that the Company invests in. Note 5 discusses the types of lending that the Company engages in.

Agricultural loans, including agricultural operating, real estate and construction loans, represented 59.7% and 60.6% of our total loan portfolio at December 31, 2017 and 2016, respectively. Commercial real estate, including commercial construction loans, represented 25.5% and 26.3% of our total loan portfolio at December 31, 2017 and 2016, respectively.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank, and the Bank’s wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company also has three wholly-owned subsidiaries, County Bancorp Statutory Trust II, County Bancorp Statutory Trust III, and Fox River Valley Capital Trust I, that are Delaware statutory trusts which have not been consolidated in accordance with accounting guidance related to variable interest entities.

Use of Estimates in Preparing Financial Statements

The preparation of consolidated financial statements in conformity with generally accepted accounting procedures of the United States (“GAAP’) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of valuation of securities available for sale, the allowance for loan losses, loan servicing rights, other real estate owned, financial instruments, and deferred tax assets. Actual results could differ from those estimates.

Business Combinations and Valuation of Loans Acquired in Business Combinations

We account for acquisitions under Financial Accounting Standards Board (“FASB”) ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. Assets acquired and liabilities assumed in a business combination are recorded at estimated fair value on their purchase date. As provided for under GAAP, management has up to 12 months following the date of the acquisition to finalize the fair values of acquired assets and assumed liabilities where it was not possible to estimate the acquisition date fair value upon consummation.

65

In particular, the valuation of acquired loans involves significant estimates, assumptions and judgments based on information available as of the acquisition date. Substantially all loans acquired in the transaction are evaluated either individually or in pools of loans with similar characteristics; since the estimated fair value of acquired loans includes a credit consideration, no carryover of any previously recorded allowance for loan losses is recorded at acquisition. A number of factors are considered in determining the estimated fair value of purchased loans including, among other things, the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, estimated holding periods, contractual interest rates compared to market interest rates, and net present value of cash flows expected to be received.

In determining the fair value of acquired loans, management calculates a nonaccretable difference (the credit mark component of the acquired loans) and an accretable difference (the market rate or yield component of the acquired loans). The nonaccretable difference is the difference between the undiscounted contractually required payments and the undiscounted cash flows expected to be collected in accordance with management’s determination of the fair value. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows will result in a reversal of the provision for loan losses to the extent of prior charges and then an adjustment to accretable yield and nonaccretable difference which would have a positive impact on interest income.

The accretable yield on acquired loans is the difference between the expected cash flows and the initial investment in the acquired loans. The accretable yield is recognized into earnings using the effective yield method over the term of the loans. Management separately monitors the acquired loan portfolio and periodically reviews loans contained within this portfolio against the factors and assumptions used in determining the fair value.

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and balances due from banks and federal funds sold, all of which mature within 90 days.

In the normal course of business, the Company maintains balances with correspondent banks. Accounts at each institution are insured by the Federal Deposit Insurance Corporation up to specified limits. Management believes these financial institutions have strong credit ratings and the credit risk related to these deposits is minimal.

Securities Available for Sale

Available for sale securities are carried at fair value with unrealized gains and losses excluded from earnings and reported separately in other comprehensive income (loss). The Company currently has no securities designated as trading or held-to-maturity. 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. They are included in non-interest income or expense and, when applicable, are reported as a reclassification adjustment in other comprehensive income (loss).

Declines in the fair value of individual available for sale securities below their cost that are other than temporary result in write-downs of the individual securities to their fair value. The Company monitors the investment security portfolio for impairment on an individual security basis and has a process in place to identify securities that could potentially have a credit impairment that is other than temporary. This process involves analyzing the length of time and the extent to which the fair value has been less than the amortized cost basis, the market liquidity for the security, the financial condition and near-term prospects of the issuer, expected cash flows, and the Company’s intent and ability to hold the investment for a period of time sufficient to recover the temporary impairment. A decline in value due to a credit event that is considered other than temporary is recorded as a loss in non-interest income.

Federal Home Loan Bank Stock

The Bank, as a member of the Federal Home Loan Bank of Chicago (“FHLB”), is required to maintain an investment in the capital stock of the FHLB based on the level of borrowings and other factors, and may invest additional amounts. Based on the redemption provisions of the FHLB, the stock has no quoted market value and is carried at cost. It is periodically evaluated by management for impairment. Because it is viewed as a long term investment, impairment is based on ultimate recovery of par value. Both stock and cash dividends are reported as income.

66

Loans Held for Sale

Loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value. Gains and losses on loan sales (sale proceeds minus carrying value) are recorded in non-interest income and direct loan origination costs and fees are deferred at origination of the loan and are recognized in non-interest income upon sale of the loan.

Loans

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balances adjusted for unearned income and the allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, non-refundable fees and direct loan origination costs on real estate and commercial loans are, in the opinion of management, insignificant and recognized as current income and are not accounted for as an adjustment of yield of the related loan categories.

The accrual of interest on mortgage and commercial loans is discontinued at the time the principal and interest is 90 days delinquent unless the credit is well-secured and in the process of collection.  Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful.

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

Allowance for Loan Losses

The allowance for loan losses (hereinafter referred to as “allowance”) is an estimate of loan losses inherent in the Company’s loan portfolio. The allowance is established through a provision for loan losses which is charged to expense. Additions to the allowance are expected to maintain the adequacy of the total allowance after loan losses and loan growth. Loan losses are charged off against the allowance when the Company determines the loan balance to be uncollectible. Cash received on previously charged off amounts is recorded as a recovery to the allowance.

The allowance consists of two primary components, general reserves and specific reserves related to impaired loans. The general component covers non-impaired loans and is based on historical losses adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on a weighted average of the actual loss history experienced by the Company over the most recent four years. The Company places more emphasis, or weight, on the more current quarters in the loss history period. This actual loss experience is adjusted for economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. These factors are inherently subjective and are driven by the repayment risk associated with each portfolio segment.

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is generally measured on a loan by loan basis by either the present value of expected future cash flows discounted at the loans’ effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

Under certain circumstances, the Company will provide borrowers relief through loan restructurings. A restructuring of debt constitutes a troubled debt restructuring (“TDR”) if the Company for economic or legal reasons related to the borrower’s financial difficulties grants a concession to the borrower that it would not otherwise consider. Restructured loans typically present an elevated level of credit risk as the borrowers are not able to perform according to the original contractual terms. Loans that are reported as TDRs are considered impaired and measured for impairment as described above. TDR concessions can include reduction of interest rates, extension of maturity dates, forgiveness of principal or interest due, or acceptance of other assets in full or partial satisfaction of the debt. Restructured loans can involve loans remaining on nonaccrual, moving to nonaccrual, or continuing on accrual status,

67

depending on the individual facts and circumstances of the borrower. Nonaccrual restructured loans are included and treated with other nonaccrual loans.

Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment disclosures, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower.

The Company maintains a separate general valuation allowance for each portfolio segment. These portfolio segments include agricultural, commercial, commercial real estate, residential real estate, and installment and consumer other with risk characteristics described as follows:

Agricultural: Agricultural loans generally possess a lower inherent risk of loss than real estate portfolio segments because these loans are generally underwritten to existing cash flows of operating businesses. Debt coverage is provided by business cash flows and economic trends influenced by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans.

Commercial: Commercial loans generally possess a lower inherent risk of loss than real estate portfolio segments because these loans are generally underwritten to existing cash flows of operating businesses. Debt coverage is provided by business cash flows, and economic trends influenced by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans.

Commercial Real Estate: Commercial real estate loans, including land and construction, generally possess a higher inherent risk of loss than other real estate portfolio segments. Adverse economic developments or an overbuilt market impact commercial real estate projects and may result in troubled loans. Trends in vacancy rates of commercial properties impact the credit quality of these loans. High vacancy rates reduce operating revenues and the ability for the properties to produce sufficient cash flow to service debt obligations.

Residential Real Estate: The degree of risk in residential mortgage and home equity lending depends primarily on the loan amount in relation to collateral value, the interest rate and the borrower’s ability to repay in an orderly fashion. These loans generally possess a lower inherent risk of loss than other real estate portfolio segments. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers’ capacity to repay their obligations may be deteriorating.

Installment and Consumer Other: The installment and consumer other loan portfolio is usually comprised of a large number of small loans. Most loans are made directly for consumer purchases. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate the borrowers’ capacity to repay their obligations may be deteriorating.

Although management believes the allowance to be adequate, ultimate losses may vary from its estimates. At least quarterly, the board of directors reviews the adequacy of the allowance, including consideration of the relevant risks in the portfolio, current economic conditions and other factors. If the board of directors and management determine that changes are warranted based on those reviews, the allowance is adjusted. In addition, the Company’s primary regulator reviews the adequacy of the allowance. The regulatory agencies may require additions to the allowance based on their judgment about information available at the time of their examinations.

Bank Premises and Equipment

Land is carried at cost. Bank premises and equipment are carried at cost, less accumulated depreciation. Depreciation is computed on the straight line method. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any recognized gain or loss is reflected in income for the period. The cost of maintenance and repairs is charged to expense as incurred; significant renewals and improvements are capitalized and a deduction is made from the property accounts for retirements of capitalized renewals or improvements. Gains and losses on dispositions are included in current operations.

Off-Balance Sheet Credit Related Financial Instruments

In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded. The Company maintains a separate allowance for off-balance sheet commitments. Management estimates anticipated losses using historical data and utilization assumptions. The allowance for off-balance sheet commitments is included in other liabilities.

68

Impairment of Long-Lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of carrying amount and the fair value less costs to sell.

Loan Servicing Rights

Servicing assets are recognized as separate assets when rights are acquired through the sale of financial assets. Servicing rights resulting from the sale or securitization of loans originated by the Company are initially measured at fair value at the date of transfer. The Company subsequently measures each class of servicing asset using the amortization method. Under the amortization method, servicing rights are amortized in proportion to and over the period of estimated net servicing income. The amortized assets are assessed for impairment or increased obligation based on fair value at each reporting date.

Fair value is based on market prices for comparable servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. These variables change from quarter-to-quarter as market conditions and projected interest rates change, and may have an adverse impact on the value of the servicing right and may result in a reduction to non-interest income.

Servicing assets measured using the amortization method are evaluated and measured for impairment. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the carrying amount of the servicing assets for that tranche. The valuation allowance is adjusted to reflect changes in the measurement of impairment after the initial measure of the impairment.

Changes in the valuation allowances are reported with loan servicing fees on the income statement. Fair value in excess of the carrying amount of servicing assets for that stratum is not recognized.

Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of loan servicing rights is netted against loan servicing fee income.

Other Real Estate Owned

Land purchased by the Bank that is held for sale is recorded at the lower of cost or market value.

Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value at the date of foreclosure less estimated costs to sell, 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 non-interest expense.

Impairment losses on assets to be held and used are measured at the amount by which the carrying amount of a property exceeds its fair value. The evaluation of impairment is inherently subjective and requires estimates that are susceptible to significant revisions as more information becomes available. Due to potential changes in conditions, it is at least reasonably possible that changes in fair values will occur in the near term and that such changes could materially affect the amounts reported in the Company’s financial statements. Costs of significant asset improvements are capitalized, whereas costs relating to holding assets are expensed. Revenue and expenses from operations and changes in the valuation allowance are included in other non-interest expense.

Cash Surrender Value of Bank Owned Life Insurance

The Company has purchased life insurance policies on certain key executives. Bank owned life insurance is recorded at its cash surrender value, or the amount that can be realized, if lower.

69

Goodwill and Core Deposit Intangible

Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired and is included as an asset on the consolidated balance sheets. Goodwill is not amortized but is subject to impairment tests on at least an annual basis. Core deposit intangible represents the value of the acquired customer core deposit bases and is included in as an asset on the consolidated balance sheets. The core deposit intangible has an estimated finite life, is amortized on an accelerated basis over a 66-month period, and is subject to periodic impairment evaluation.

Management will periodically review the carrying value of its long-lived and intangible assets to determine if any impairment has occurred or whether changes in circumstances have occurred that would require a revision to the remaining useful life, in which case an impairment charge would be recorded as an expense in the period of impairment. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. Goodwill was $5.0 million at December 31, 2017 and 2016.  There was no impairment charge to goodwill or core deposit intangible related to the Fox River Valley acquisition at December 31, 2017.  The net book value of core deposit intangible was $0.9 million and $1.4 million at December 31, 2017 and December 31, 2016, respectively.  Goodwill and core deposit intangible are included on the consolidated balance sheets.

Income Taxes

The Company accounts for income taxes in accordance with income tax accounting guidance, which sets out a consistent framework to determine the appropriate level of tax reserves to maintain for uncertain tax positions.

The 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 determined based on the tax effects of the temporary 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%; 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% 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 the some portion or all of the deferred tax asset will not be realized.  For the year ended December 31, 2017, the value of our net deferred tax asset was reduced by $0.9 million and recorded as additional income tax expense as a result of the Tax Act that was enacted on December 22, 2017.

The Company files income taxes returns in the U.S. federal jurisdiction and in the state of Wisconsin. The Company is no longer subject to U.S. federal or state income tax examinations by tax authorities for years before 2014.

The Company recognizes interest and penalties on income taxes, if any, as a component of other non-interest expense.

Comprehensive Income

Recognized revenue, expenses, gains, and losses are included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on securities available for sale, are reported as a separate component of the equity section of the consolidated balance sheet, such items, along with net income, are components of comprehensive income.

Equity Incentive Plan

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

70

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

Treasury Stock

Common stock shares repurchased are recorded as treasury stock at cost.

Earnings per Share

Basic earnings per share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional potential 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 outstanding stock options, and are determined using the treasury stock method.

Treasury shares are not deemed outstanding for earnings per share calculations.

Transfers of Financial Assets

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

The transfer of a participating interest in an entire financial asset must also meet the definition of a participating interest. A participating interest in a financial asset has all of the following characteristics: (1) from the date of transfer, it must represent a proportionate (pro rata) ownership interest in the financial asset, (2) from the date of transfer, all cash flows received, except any cash flows allocated as any compensation for servicing or other services performed, must be divided proportionately among participating interest holders in the amount equal to their share ownership, (3) the rights of each participating interest holder must have the same priority, and (4) no party has the right to pledge or exchange the entire financial asset unless all participating interest holders agree to do so.

Advertising Costs

Advertising costs are expensed as incurred.

Fair Value of Financial Instruments

Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 20. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect the estimates.

Segments

The Company’s operations consist of one segment, community banking.  The operating results of this segment are regularly reviewed by management to make decisions about resource allocations and to assess performance.  Selected information is not presented separately for the Company's reportable segment, as there is no material difference between that information and the corresponding information in the consolidated financial statements.

In November 2015, FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes. This ASU requires entities to present deferred tax assets (DTAs) and deferred tax liabilities (DTLs), along with any related valuation allowance, as noncurrent in a balance sheet. This ASU eliminates current guidance requiring deferred taxes for each jurisdiction to be presented as a net current asset or liability and a net noncurrent asset or liability. As a result, each jurisdiction would have one net noncurrent DTA or DTL balance. The ASU does not change the existing requirement that only permits offsetting DTAs and DTLs within a particular jurisdiction. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016, with early adoption permitted. This guidance was adopted during 2017 and did not have any material impact on the Company’s consolidated financial statements.

In January 2016, FASB issued ASU No. 2016-01, Financial Instruments: Recognition and Measurement of Financial Assets and Financial Liabilities, to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This amendment supersedes the guidance to classify equity securities with readily determinable fair values into different categories, requires equity securities to be measured at fair value with changes in the fair value recognized through net income, and simplifies the impairment assessment of equity investments without readily determinable fair values. The amendment requires public business entities that are required to disclose the fair value of financial instruments measured at amortized cost on the balance sheet to measure that fair value using the exit price notion. The amendment requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option. The amendment requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or in the accompanying notes to the financial statements. The amendment reduces diversity in current practice by clarifying that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity’s other deferred tax assets. This amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Entities should apply the amendment by means of a cumulative-effect adjustment as of the beginning of the fiscal year of adoption, with the exception of the amendment related to equity securities without readily determinable fair values, which should be applied prospectively to equity investments that exist as of the date of adoption. The Company does not have any equity securities in its portfolio; the adoption of this ASU will have no effect on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases: Amendments to the FASB Accounting Standards Codification which requires companies to recognize all leases as assets and liabilities on the consolidated balance sheet. This ASU retains a distinction between finance leases and operating leases, and the classification criteria for distinguishing between finance leases and operating leases are substantially similar to the classification criteria for distinguishing between capital leases and operating leases in the current accounting literature. The result of retaining a distinction between finance leases and operating leases is that under the lessee accounting model, the effect of leases in a consolidated statement of comprehensive income and a consolidated statement of cash flows is largely unchanged from previous GAAP. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Earlier application is permitted. The Company is currently evaluating it leases and determining the effect of this ASU will have on its financial statements and disclosures, if any.

In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation to simplify several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The amendments in this update became effective beginning January 1, 2017 and did not have a significant impact the Company’s financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses, to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date.  The amendment replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.  This amendment is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years with early adoption permitted for the fiscal year beginning after December 15, 2018, including interim periods within those fiscal years.  Entities should apply this amendment a modified-retrospective approach, through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective.  The Company has engaged a third-party software consultant to assist in developing our loss model methodology, and is currently gathering historical data.  At this time, the effect this ASU will have on its consolidated financial statements is unknown.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments, to reduce the existing diversity in practice in how certain cash receipts and payments are presented and classified on the

72

statement of cash flows.  The amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with early adoption permitted including adoption in an interim period.  Entities should apply this amendment as of the beginning of the first reporting period in which the guidance is effective.  The adoption of this guidance is not expected to have a material impact on its consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash: A Consenus of the FASB Emerging Issues Task Force, to standardize the classification and presentation of changes to restricted cash on the statement of cash flows.  The amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with early adoption permitted including adoption in an interim period.  Entities should apply this amendment using a retrospective transition method to each period presented.  The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04 Intangibles – Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment.  This update eliminates Step 2 of the goodwill impairment test, and instead, recognizes an impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value not to exceed the total amount of goodwill allocated.  The Company early adopted this amendment effective January 1, 2017 for its goodwill impairment analysis.  The result of this amendment had no impact on the Company since its goodwill is not impaired as of December 31, 2017.

In March 2017, the FASB issued updated guidance codified within ASU No. 2017-08, Receivables – Nonrefundable Fees and Other Costs, which is intended to enhance the accounting for the amortization of premiums for purchased callable debt securities. The amendment is effective for fiscal years beginning after December 15, 2018, with early adoption permitted including adoption in an interim period. The Company is currently evaluating the effects this ASU will have on its consolidated financial statements.

In May 2017, the FASB issued updated guidance codified within ASU No. 2017-09, Compensation – Stock Compensation to provide clarity and reduce the diversity in practice and cost and complexity of applying the guidance when there is a change of terms condition of share-based awards. The amendment is effective for fiscal years beginning after December 15, 2017, with early adoption permitted including adoption in an interim period. The adoption of this ASU is not expected to have a significant impact on the Company’s consolidated financial because modification to share-based awards are rarely made.

In September 2017, the FASB issued updated guidance codified within ASU No. 2017-13, Revenue Recognition, Revenue from Contracts with Customers, Leases (Topic 840), and Leases (Topic 842) to clarify the amendment to the SEC paragraphs pursuant to the staff announcement on July 20, 2017 and update ASU No. 2016-20 Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers which was an update to ASU 2014-09 Revenue from Contracts with Customers, is the culmination of efforts by the FASB and the International Accounting Standards Board to develop a common revenue standard for GAAP and International Financial Reporting Standards. ASU 2014-09 supersedes Topic 605—Revenue Recognition and most industry-specific guidance. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those good or services. The guidance in ASU 2014-09 describes a 5-step process entities can apply to achieve the core principle or revenue recognition and requires disclosures sufficient to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers and the significant judgments used in determining that information. The amendments in ASU 2016-20 narrow the aspects of the guidance issued within ASU 2014-09 and are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period and early application is not allowed. The Company is currently cataloging revenue streams and reviewing current policies and practices to identify differences under this ASU.  The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which requires companies to reclassify the stranded effects in other comprehensive income to retained earnings as a result of the change in the tax rates under the Tax Cuts and Jobs Act (the 2017 Tax Act”).  The amendment is effective for fiscal years beginning after December 15, 2018, with early adoption permitted including adoption in an interim period.  The Company plans to early adopt this amendment during the first quarter of 2018 and will include the impact of the reclassification from other comprehensive income to retained earnings is included in the Statement of Changes in Shareholders’ Equity.

NOTE 2—ACQUISITION

On May 13, 2016, the Company completed its acquisition of Fox River Valley, a Wisconsin corporation, pursuant to the Agreement and Plan of Merger dated November 19, 2015 (the “Merger Agreement”) by and among the Company, County Acquisition LLC, a wholly-owned subsidiary of the Company, and Fox River Valley, whereby the Company acquired Fox River Valley and its wholly-owned bank subsidiary, The Business Bank, through the merger of Fox River Valley into County Acquisition LLC (which subsequently dissolved) and the merger of The Business Bank into Investors Community Bank.

The purpose of the acquisition was for strategic reasons beneficial to the Company. The acquisition is consistent with its growth plans to expand into the markets of Appleton and Green Bay, Wisconsin and diversify its loan portfolio to decrease its agricultural concentration.  The Company believes it is well-positioned to achieve stronger financial performance and enhance shareholder value through synergies of the combined operations.

Under the terms of the Merger Agreement, the Company acquired Fox River Valley for aggregate consideration of approximately $28.7 million which was comprised of $14.45 million in cash and 712,830 shares of the Company’s common stock valued at $20 per share on May 13, 2016.  The system integration was completed, and the two branches of The Business Bank opened on May 16, 2016 as branches of Investors Community Bank.

The Company accounted for the transaction under the acquisition method of accounting under FASB Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, and thus, the financial position and results of operations of Fox River Valley prior to the closing date were not included in the accompanying consolidated financial statements.  The accounting required assets purchased and liabilities assumed to be recorded at their respective fair values at the date of acquisition. The Company determined the fair value with the assistance of third party valuations, appraisals, and third party advisors.  The estimated fair values were subject to refinement as additional information relative to the closing date fair values became available through the measurement period of approximately one year from consummation.

During the year ended December 31, 2016, the Company incurred $2.6 million of merger related costs which are included in the consolidated statement of operations in other non-interest expense.

The fair value of the assets acquired and liabilities assumed on May 13, 2016 were as follows:

	As recorded by Fox River Valley		Fair value adjustment			As recorded by the Company

	$	76,388	$	(959	)	$	604	$	(3	)	$	76,992	$	(962	)

The unrealized loss on the investments at December 31, 2017 and 2016 was due to normal fluctuations and pricing inefficiencies. The contractual terms of the investments do not permit the issuers to settle the securities at a price less than the amortized cost basis of the investment. Because the Company does not intend to sell the investments and it is not more-likely-than-not that the Company will be required to sell the investments before recovery of the amortized cost basis, which may be maturity, the Company did not consider these investments to be other-than-temporarily impaired at December 31, 2017 and 2016.

Other-Than-Temporary Impairment

Upon acquisition of a security, the Company decides whether it is within the scope of the accounting guidance for beneficial interests in securitized financial assets or will be evaluated for impairment under the accounting guidance for investments in debt and equity securities.

The accounting guidance for beneficial interests in securitized financial assets provides incremental impairment guidance for a subset of the debt securities within the scope of the guidance for investments in debt and equity securities. For securities where the security is a beneficial interest in securitized financial assets, the Company uses the beneficial interest in securitized financial asset impairment model. For securities where the security is not a beneficial interest in securitized financial assets, the Company uses debt and equity securities impairment model.

The Company routinely conducts periodic reviews to identify and evaluate each investment security to determine whether an other-than-temporary impairment has occurred. Economic models are used to determine whether an other-than-temporary impairment has occurred on these securities. While all securities are considered, the securities primarily impacted by other-than-temporary impairment testing are private-label mortgage-backed securities. For each private-label mortgage-backed security in the investment portfolio (including but not limited to those whose fair value is less than their amortized cost basis) an extensive, regular review is conducted to determine if an other-than-temporary impairment has occurred. Various inputs to the economic models are used to determine if an unrealized loss is other-than-temporary. The most significant inputs are the default rate and the severity of the decline in value. Other inputs may include the actual collateral attributes, which include geographic concentrations, credit ratings, and other performance indicators of the underlying assets.

There were no securities with material unrealized losses existing longer than 12 months, and no securities with unrealized losses which management believed were other-than-temporarily impaired, at December 31, 2017 or 2016.

At December 31, 2017, 127 debt securities had unrealized losses with aggregate depreciation of 1.27% from the Company’s amortized cost basis. At December 31, 2016, 117 debt securities had unrealized losses with aggregate depreciation of 1.25% from the Company’s amortized cost basis.  These unrealized losses related principally to Government National Mortgage Association mortgage-backed and municipal debt securities. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and industry analysts’ reports. As management has the intent and ability to hold debt securities until maturity for the foreseeable future if classified as available for sale, the decline is not deemed to be other-than-temporary.

Troubled Debt Restructurings

The Company had allocated $0.9 million and $0.5 million of specific reserves to customers whose loan terms have been modified in troubled debt restructurings at December 31, 2017 and 2016, respectively. The Company had no additional lending commitments at December 31, 2017 and 2016 to customers with outstanding loans that are classified as troubled debt restructurings.

A TDR on nonaccrual status is classified as a nonaccrual loan until evaluation supports reasonable assurance of repayment and of performance according to the modified terms of the loan. Once this assurance is reached, the TDR is classified as a restructured loan.  At December 31, 2017, there were $13.4 million TDR loans, of which $4.4 million were classified as nonaccrual and $9.0 million were classified as restructured and accruing, and there were $0.1 million unfunded commitments on these loans. At December 31, 2016, there were $14.0 million TDR loans, of which $9.7 million were classified as nonaccrual and $4.3 million were classified as restructured and accruing. There were $35,000 unfunded commitments on these loans.

Credit Quality Indicators

The Company categorizes loans into risk categories based on relevant information about the ability of the borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. The Company analyzes agricultural, commercial, and commercial real estate loans individually by classifying the credits as to credit risk. The process of analyzing loans for changes in risk rating is ongoing through routine monitoring of the portfolio and annual internal credit reviews for credits with total exposure in excess of $0.3 million. The Company uses the following definitions for credit risk ratings:

Sound. Credits classified as sound show very good probability of ongoing ability to meet and/or exceed obligations.

Acceptable. Credits classified as acceptable show a good probability of ongoing ability to meet and/or exceed obligations.

Satisfactory. Credits classified as satisfactory show an average probability of ongoing ability to meet and/or exceed obligations.

Low Satisfactory. Credits classified as low satisfactory may have more inconsistent earnings, but have a fair probability of ongoing ability to meet and/or exceed obligations.

Watch. Credits classified as watch show some questionable probability of ongoing ability to meet and/or exceed obligations.

Special Mention. Credits classified as special mention show potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loans or of the institution’s credit position at some future date.

Substandard – Performing.Credits classified as substandard – performing generally have well-defined weaknesses. Collateral coverage is adequate and the loans are not considered impaired.  Payments are being made and the loans are on accrual status.

81

Substandard - Impaired.Credits classified as substandard generally have well-defined weaknesses that jeopardize the repayment of the debt. They have a distinct possibility that a loss will be sustained if the deficiencies are not corrected.  Loans are considered impaired.  Loans are either exhibiting signs of delinquency, are on non-accrual or are identified as a TDR.

Doubtful. Credits classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable.

The Company categorizes residential real estate, installment and consumer other loans as satisfactory at the time of origination based on information obtained as to the ability of the borrower(s) to service their debt, such as current financial information, employment status and history, historical payment experience, credit scores and type and amount of collateral among other factors. The Company updates relevant information on these types of loans at the time of refinance, troubled debt restructuring or other indications of financial difficulty, downgrading as needed using the same category descriptions as for agricultural, commercial, and commercial real estate loans. In addition, the Company further considers current payment status as an indicator of which risk category to assign the borrower.

The greater the level of deteriorated risk as indicated by a loan’s assigned risk category, the greater the likelihood a loss will occur in the future. If the loan is impaired then the loan loss reserves for the loan are recorded at the loss level of impairment. If the loan is not impaired, then its loan loss reserves are determined by the application of a loss rate that increases with risk in accordance with the allowance for loan loss analysis.

Based on the most recent analysis performed by management, the risk category of loans by class of loans is as follows:  

	As of December 31, 2017
	Sound/ Acceptable/ Satisfactory/ Low Satisfactory		Watch		Special Mention		Substandard Performing		Substandard Impaired		Total Loans
	(dollars in thousands)

NOTE 6—PREMISES AND EQUIPMENT

Premises and equipment consisted of the following:

	December 31,						Estimated
	2017			2016			Useful Life
	(dollars in thousands)
Land	$	1,316		$	1,328		N/A
Construction in process		250			—		N/A
Bank premises		8,554			8,758		35-40 years

		14,901			14,133
Accumulated depreciation and amortization		(5,239	)		(4,314	)
	$	9,662		$	9,819

Depreciation and amortization expense charged to operations for the years ended December 31, 2017, 2016, and 2015 totaled $1.0 million, $980 thousand, and $592 thousand, respectively.

NOTE 7—LOAN SERVICING RIGHTS

Loans serviced for others are not included in the accompanying consolidated balance sheets. The risks inherent in servicing assets relate primarily to changes in prepayments that result from shifts in interest rates. The unpaid principal balances of mortgage and other loans serviced for others were approximately $600.7 million and $577.0 million at December 31, 2017 and 2016, respectively.

The following summarizes servicing rights capitalized and amortized, along with the aggregate activity in related valuation allowances: 

	December 31,
	2017			2016
	(dollars in thousands)
Loan servicing rights:
Balance, beginning of period	$	9,264		$	8,145
Additions		2,431			4,794
Disposals		(564	)		(1,552	)
Amortization		(2,181	)		(2,123	)
Balance, end of period	$	8,950		$	9,264

The fair values of these rights were approximately $12.5 million and $12.2 million at December 31, 2017 and 2016, respectively. The fair value of servicing rights was determined using an assumed discount rate of 10% and prepayment speeds primarily ranging from 4% to 9%, depending upon the stratification of the specific right, and nominal anticipated credit losses.

NOTE 8 – GOODWILL AND CORE DEPOSIT INTANGIBLE

The excess of the purchase price in an acquisition over the fair value of net assets acquired consists primarily of goodwill and the core deposit intangible. Goodwill is not amortized but is instead subject to impairment tests on at least an annual basis. Core deposit intangible, which arose from value ascribed to the deposit base of a bank acquired, has an estimated finite life and is amortized on an accelerated basis to expense over a 66-month period.

Management will periodically review the carrying value of its long-lived and intangible assets to determine if any impairment has occurred, in which case an impairment charge would be recorded as an expense in the period of impairment, or whether changes in circumstances have occurred that would require a revision to the remaining useful life which would impact expense prospectively. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. There was no impairment charge to goodwill or core deposit intangible at December 31, 2017 or 2016.  

Goodwill:  Goodwill resulted from the acquisition of Fox River Valley on May 13, 2016.  The carrying amount of goodwill was $5.0 million at December 31, 2017 and 2016. See Note 2 for additional information on the acquisition.

Core deposit intangible:  Core deposit intangible, primarily related to acquired customer relationships, is amortized over its estimated finite life.  The core deposit intangible related to the Fox River Valley acquisition had a gross carrying amount of $1.8 million.

83

Amortization on core deposit intangible was $882 and $360 thousand for the year ended December 31, 2017 and 2016, respectively. See Note 2 for additional information on the acquisition.

The terms of security agreements with the FHLB require the Bank to pledge collateral for its borrowings. The collateral consists of qualifying first mortgage loans, certain securities available for sale, and stock of the FHLB.

The Bank had no irrevocable letters of credit with the FHLB as of December 31, 2017 and 2016.

Future maturities of borrowings were as follows:

	December 31,
	2017		2016
	(dollars in thousands)
1 year or less	$	60,100	$	29,395
1 to 2 years		25,000		35,100

3 to 4 years		18,000		18,400
Over 4 years		—		10,000
	$	121,500	$	107,895

As of December 31, 2017 and 2016, the Bank also had a $50.0 million line-of-credit available with the Federal Reserve Bank of Chicago.  Borrowings under this line of credit are limited by the amount of securities pledged by the Bank as collateral, which totaled $8.6 million and $11.3 million at December 31, 2017 and 2016, respectively.  There were no outstanding advances included in other borrowings at December 31, 2017 or 2016, respectively.  

On September 14, 2017, the Company entered into a credit agreement with U.S. Bank, National Association for a $15.0 million revolving line-of-credit with an interest rate equal to the one-month LIBOR rate plus 2.25%.  The line also bears a non-usage fee of 0.275% per annum.  The non-usage fee for year ended December 31, 2017 was $5 thousand.  The line did not have an outstanding balance as of December 31, 2017, and was unused during the year.

Other borrowings are borrowings as a result of sold loans that do not qualify for sale accounting. These agreements are recorded as financing transactions as the Bank maintains effective control over the transferred loans. The dollar amount of the loans underlying the sale agreements continues to be carried in the Bank’s loan portfolio, and the transfer is reported as a secured borrowing with pledge of collateral.  At December 31, 2017 and 2016, the amounts of these borrowings were $1.3 million and $2.0 million, respectively.

Also included in other borrowings is the capital lease for our full service banking location in Appleton, Wisconsin that was assumed in connection with our merger of Fox River Valley.  Under the terms of the current triple-net lease the Company is obligated to pay monthly rent of $15 thousand, and the lease term expires in April 2019.  As of December 31, 2017, liability remaining under the capital lease was $41 thousand, and the amortization related to the lease was $148 thousand and was included in other non-interest expense.  As of December 31, 2016, liability remaining under the capital lease was $189 thousand, and the amortization related to the lease was $85 thousand and was included in other non-interest expense.

NOTE 12—SUBORDINATED DEBENTURES AND SBLF PREFERRED STOCK

In September 2005 and June 2006, the Company formed wholly owned subsidiary business trusts, County Bancorp Statutory Trust II (“Trust II”) and County Bancorp Statutory Trust III (“Trust III”) (together, the “Trusts”), which are both Delaware statutory trusts, for the purpose of issuing capital securities which qualify as Tier 1 capital of the Company. Trust II issued at par $6.0 million of floating rate capital securities in an exempt offering. The capital securities are nonvoting, mandatorily redeemable in 2035, and guaranteed by the Company. Trust III issued at par $6.0 million of floating rate capital securities in an exempt offering. The capital securities are nonvoting, mandatorily redeemable in 2036, and guaranteed by the Company.

86

The capital securities carry an interest rate identical to that of the related debentures. For Trust II, holders of capital securities are entitled to receive cumulative cash distributions at a rate of 6.1% through September 2015, and a rate based on the three month LIBOR plus 1.53% thereafter through maturity, which was 3.12% as of December 31, 2017. For Trust III, holders of capital securities are entitled to receive cumulative cash distributions at a rate based on the three month LIBOR plus 1.69% through maturity, which was 3.28% as of December 31, 2017.

The distribution rate payable on the capital securities is cumulative and payable quarterly in arrears. The Company has the right, subject to events of default, to defer payments of interest on the debentures at any time by extending the interest payment period for a period not exceeding 20 consecutive quarters with respect to each deferral period, provided that no extension period may extend beyond the redemption or maturity dates of the debentures. The capital securities are subject to mandatory redemption upon payment of the debentures. Trust II and III mature on September 15, 2035 and June 15, 2036, respectively, may be called not earlier than September 15, 2015 and June 15, 2016, respectively, if certain conditions were met, or at any time within 180 days following the occurrence and continuation of certain changes in either tax treatment or the capital treatment of Trust II and Trust III, the debentures, or the capital securities. If the debentures are redeemed before they mature, the redemption price will be the principal amount plus any accrued but unpaid interest. The Company has the right to terminate Trust II and Trust III and cause the debentures to be distributed to the holders of the capital securities in liquidation of such Trusts.

The Company owns all of the outstanding common securities of Trust II and Trust III. The Trusts used the proceeds from the issuance of their capital securities to buy floating rate junior subordinated deferrable interest debentures (“debentures”) issued by the Company. These debentures are the Trusts’ only assets, and interest payments from these debentures finance the distributions paid on the capital securities. These debentures are unsecured, rank junior, and are subordinate in the right of payment to all senior debt of the Company.

The capital securities of Trust II and Trust III have been structured to qualify as Tier 1 capital for regulatory purposes. However, the securities cannot be used to constitute more than 25 percent of the Company’s “core” Tier 1 capital according to regulatory requirements. The Company utilized the proceeds of the Trust II issuances for general corporate purposes and Trust III issuances to redeem the securities of County Bancorp Statutory Trust I.

In connection with the merger with Fox River Valley, the Company also acquired Fox River Valley’s wholly-owned subsidiary Fox River Valley Capital Trust I, a Delaware statutory trust (the “FRV Trust I”), which issued capital securities that qualify for Tier II capital of the Company.  The Company assumed the $3.6 million of floating rate, junior subordinated debentures, of which the Company owns $0.1 million. The debentures are non-voting, mandatorily redeemable in 2033 and guaranteed by the Company.

The distribution rate payable on the debentures is cumulative and payable quarterly in arrears. The Company has the right, subject to events of default, to defer payments of interest on the debentures at any time by extending the interest payment period not exceeding 20 consecutive quarters with respect to each deferral period, provided that no extension period may extend beyond the redemption or maturity date of the debentures. Interest is current through the most recent due date of December 15, 2017.

The FRV Trust I may redeem some or all of the capital securities, at par, with 30 days advance notice, on or after November 30, 2008, but only on May 30 or November 30 of any given year, and only in a minimum amount of $500,000 and in increments of $10,000 thereafter, or the full amount of the capital securities. The FRV Trust I may redeem all of the capital securities at any time upon the occurrence and during the continuation of a Tax Event, an Investment Company Event or a Capital Treatment Event (each as defined in the trust agreement for the FRV Trust I), at any time within 90 days following such event.

The FRV Trust I debentures carry an interest rate equal to 5-year LIBOR plus 3.40%, which resets every five years. The current rate is equal to 4.855% through November 30, 2018. Interest payments are due quarterly.

The Small Business Lending Fund (SBLF) preferred stock of the Company qualified as Tier 1 capital and accrued noncumulative dividends, payable quarterly, on each January 1, April 1, July 1 and October 1. The dividend rate, as a percentage of the liquidation amount, fluctuated on a quarterly basis during the first 10 quarters during which the preferred stock was outstanding, based upon changes in the level of “Qualified Small Business Lending”, by the Company’s subsidiary bank. The dividend rate was based upon the percentage change in QSBL between each dividend period and the baseline QSBL level, as determined in accordance with the Purchase Agreement.

Beginning with the fourth quarter of 2013, the dividend rate was fixed at an annualized 1.00% through the fourth quarter of 2015.  Such dividends were not cumulative, but the Company could only declare and pay dividends on its common stock (or any other equity securities junior to the SBLF Preferred Stock) if it had declared and paid dividends for the current dividend period on the SBLF Preferred Stock, and would be subject to other restrictions on its ability to repurchase or redeem other securities.

The Company could redeem the shares of SBLF Preferred Stock, in whole or in part, at any time at a redemption price equal to the sum of the liquidation amount per share ($1,000 per share) and the per-share amount of any unpaid dividends for the then-current

87

period, subject to any required prior approval by the Company’s primary federal banking regulator. The terms of the SBLF Preferred Stock imposed limits on the ability of the Company to pay dividends and repurchase shares of common stock. Under the terms of the SBLF Preferred Stock, no repurchases could be effected, and no dividends could be declared or paid on preferred shares ranking pari passu with the SBLF Preferred Stock, junior preferred shares, or other junior securities (including the common stock) during the current quarter and for the next three quarters following the failure to declare and pay dividends on the SBLF Preferred Stock, except that, in any such quarter in which the dividend was paid, dividend payments on shares ranking pari passu could be paid to the extent necessary to avoid any resulting material covenant breach.  The Company redeemed the SBLF Preferred Stock on February 23, 2016.

NOTE 13—INCOME TAXES

NOTE 14—OFF-BALANCE SHEET ACTIVITIES

Credit-Related Financial Instruments

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

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

Financial instruments with contract amounts representing credit risk as of December 31, 2017 and 2016 were as follows:

	December 31,
	2017		2016
	(dollars in thousands)
Commitments to extend credit and unused lines of credit, including unused    credit card lines	$	235,807	$	181,124
Standby letters of credit		5,357		5,599

Commitments to extend credit are agreements to lend funds 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. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if deemed necessary by the Bank, 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 to existing customers. These lines of credit are usually collateralized and contain a specified maturity date and may not be drawn upon to the total extent to which the Bank is committed.

89

Standby letters of credit are conditional commitments issued by the Bank to guarantee the payment or the performance of a Bank customer to a third party. Both standby and performance letters of credit are generally issued for terms of one to four years. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank generally holds collateral supporting these commitments.

NOTE 15—DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Derivative Loan Commitments

Loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. The Company enters into commitments to fund loans at specified times in the future, with the intention that these loans will subsequently be sold in the secondary market. A loan commitment binds the Company to lend funds to a potential borrower at a specified interest rate and within a specified period of time, generally up to 60 days after inception of the rate lock.

Outstanding derivative loan commitments expose the Company to the risk that the price of the loans arising from exercise of the loan commitment might decline from inception of the rate lock to funding of the loan due to increases in interest rates. If interest rates increase, the value of these loan commitments decreases. Conversely, if interest rates decrease, the value of these loan commitments increases. The notional amount of interest rate lock commitments was $0 at both December 31, 2017, 2016, and 2015.

Collateral Requirements

To reduce credit risk related to the use of derivatives financial instruments, the Company might deem it necessary to obtain collateral. The amount and nature of the collateral obtained is based on the Company’s credit evaluation of the customer. Collateral held varies, but may include cash, securities, accounts receivable, inventory, property, plant and equipment and real estate. If the counterparty does not have the right and ability to redeem the collateral or the Company is permitted to sell or re-pledge the collateral on short notice, the Company records the collateral in its balance sheet at fair value with a corresponding obligation to return it.

NOTE 16—EMPLOYEE BENEFIT PLANS

The Company has a 401(k) plan covering substantially all employees. The Company’s contributions are based upon the discretion of the board of directors. Total expense for the years ended December 31, 2017, 2016, and 2015 was $656 thousand, $630 thousand, and $405 thousand, respectively.

On May 1, 2006, the Company entered into salary continuation agreements with five key employees. Under these agreements, the key employees will receive $60,000 per year beginning on the later of attaining age 65 or their separation from service, and continuing for 15 years.

During 2011, the Company entered into a salary continuation agreement with an additional key employee. Under this agreement, the key employee will receive amounts ranging between $36,000 and $60,000 annually, depending on the employee’s age at separation, commencing upon retirement and continuing for 15 years.     

As of December 31, 2017, 2016, and 2015, respectively, the Company had accrued $2.0 million, $1.9 million, and $2.0 million in conjunction with these salary continuation agreements.  The payouts under these agreements for the years ending December 31, 2017, 2016, and 2015 were $105 thousand, $45 thousand, and $45 thousand, respectively. 

NOTE 17—EQUITY INCENTIVE PLAN

In 2016, the shareholders’ approved the Company’s 2016 Equity Incentive Compensation Plan (the “Plan”), which replaced the Company’s 2012 Equity Incentive Compensation Plan.  Under the Plan, the Company may grant options and stock awards to its directors, officers and employees for shares of common stock. Both qualified and non-qualified stock options, stock appreciation rights, restricted stock, and restricted stock units may be granted and issued, respectively, under the Plan.

The exercise price of options is no less than the market price of the Company’s stock on the date of grant and an option’s maximum term is ten years. Vesting periods for options and restricted stock range from one to five years from the date of grant.  

On February 27, 2017, the Company granted 5,988 restricted stock awards to certain members of management and lenders with a grant date value of $27.31 per share which was the Nasdaq Official Closing Price on that day.  The shares were awarded at no cost to the employee and have a ratable annual vesting period of five years from date of issue.  Compensation cost to be recognized over the

90

five-year period, net of income tax, is $131 thousand.  As of December 31, 2017, none of the awards were vested, and 948 shares had been forfeited.  Unrecognized compensation expense, at December 31, 2017, net of income tax, was $216 thousand.

On February 27 2017 and June 20, 2017, the Company granted 4,461 and 4,230 restricted stock unit awards, respectively to certain members of management, lenders, and directors with grant date values of $27.31 and $23.66, respectively per share which was the Nasdaq official closing price on that day.  The shares were awarded at no cost to the employee.  The shares issued on February 27, 2017, have a ratable annual vesting period of five years from date of issue, and the shares issued on June 20, 2017 have a vesting period of one year from date of issue.  Compensation cost to be recognized over the vesting period is $178 thousand, net of income tax.  As of December 31, 2017, none of the awards were vested or forfeited.  Unrecognized compensation expense, at December 31, 2017, net of income tax, was $93 thousand.

The fair value of each option grant was estimated on the grant date using the Black-Scholes option-pricing model with the following assumptions:

	December 31,
	2017			2016
Risk-free interest rates	2.08-2.27%			1.49-1.64%
Dividend yields	0.74%-0.99%			0.96%-1.02%
Expected volatility		35.00	%		24.00	%
Weighted-average expected life of options	7.00 years			7.00 years

The expected volatility is based on historical volatility. The risk free rates for periods within the contractual life of the awards are based on the U.S. Treasury yield curve in effect at the time of the grant. The expected life is based on historical exercise experience. The dividend yield assumption is based on the Company’s history of declaring dividends on its common stock.

The activity of the Company’s outstanding stock options for the years ended December 31, 2017 and 2016 were as follows:

	December 31, 2017							December 31, 2016
	Number of Options			Weighted-Average Exercise Price		Aggregate Intrinsic Value (1)		Number of Options			Weighted-Average Exercise Price		Aggregate Intrinsic Value (1)

Weighted-average fair value of options granted during the period (2)				$	9.54						$	4.89

(1) The aggregate intrinsic value of a stock option in the table above represents the total pre-tax intrinsic value (the amount by which the current market value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders had all option holders exercised their options on December 31, 2017 and 2016. This amount changes based on changes in the market value of the Company’s stock.

(2) The fair value (present value of the estimated future benefit to the option holder) of each option grant is estimated on the date of grant using the Black-Scholes option pricing model.

As of December 31, 2017, unrecognized share-based compensation expense related to nonvested options and restricted stock amounted to $569 thousand and is expected to be recognized over a weighted average period of 1.53 years.

NOTE 18—REGULATORY MATTERS

The Company (on a consolidated basis) and Bank are each subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly

93

additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and 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 the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios (set forth in the following table) of Total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined in the regulations), of Tier 1 capital (as defined in the regulations) to average assets (as defined in the regulations), and of Tier 1 Common Equity (as defined) to risk-weighted assets. Management believed, as of December 31, 2017 and 2016, that the Company and Bank met all capital adequacy requirements to which they were subject.

As of December 31, 2017, the most recent notification from the banking regulators categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain minimum Total risk-based, Tier 1 risk-based, Tier 1 leverage and Tier 1 Common Equity ratios as set forth in the following tables. There were no conditions or events since the notification that management believes have changed the Bank’s category.

The Company’s and Bank’s actual capital amounts and ratios are presented in the following table:

	Actual					Minimum For Capital Adequacy Purposes(a):					Minimum To Be Well Capitalized Under Prompt Corrective Action Provisions:

The Basel III Rule, which became effective January 1, 2015, revised the prompt corrective action requirements by, among other things: (i) introducing a Common Equity Tier 1 ratio requirement at each level (other than critically undercapitalized), with the required Common Equity Tier 1 ratio being 6.5% for “well-capitalized” status; (ii) increasing the minimum Tier 1 capital ratio requirement for each category (other than critically undercapitalized), with the minimum Tier 1 capital ratio for “well-capitalized” status being 8% (compared to the prior ratio of 6%); and (iii) eliminating the former provision that provided that a bank with a composite supervisory rating of 1 may have a 3% Leverage Ratio and still be adequately capitalized. The Basel III Rule did not change the total risk based capital requirement for any prompt corrective action category.  The Basel III Rule also implemented a capital conservation buffer that is added to the minimum requirements for capital adequacy purposes.  The capital conservation buffer is subject to a three year phase-in period that began on January 1, 2016 and will be fully phased in on January 1, 2019 at 2.5%.  The required phase-in capital conservation buffer during 2017 and 2016 was 1.25% and 0.625%, respectively.  As of December 31, 2017 and 2016, the ratios for the Company and the Bank were sufficient to meet the fully phased-in conservation buffer.

NOTE 20—FAIR VALUE MEASUREMENTS

Determination of Fair Value

The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimate of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.

Guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is considered a reasonable point within the range that is most representative of fair value under current market conditions.

Fair Value Hierarchy

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

Level 1—Valuation is based on quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.

95

Level 2—Valuation is based on inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. The valuation may be based on quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3—Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which determination of fair value requires significant management judgment or estimation.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

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

Cash and Cash Equivalents and Interest-Bearing Deposits in Banks

The carrying amounts of cash and short-term instruments approximate fair values based on the short-term nature of the assets.

Fair values of other interest-bearing deposits are estimated using discounted cash flow analyses based on current rates for similar types of deposits.

Securities Available for Sale

Where quoted prices are available in an active market, the Company classifies the securities within Level 1 of the valuation hierarchy. Securities are defined as both long and short positions. Level 1 securities include highly liquid government bonds and exchange-traded equities.

If quoted market prices are not available, the Company estimates fair values using pricing models and discounted cash flows that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes and credit spreads.

Examples of such instruments, which would generally be classified within Level 2 of the valuation hierarchy, include U.S. government and agency securities, corporate bonds and other securities. Mortgage-backed securities that are included in Level 2 if observable inputs are available. In certain cases where there is limited activity or less transparency around inputs to the valuation, the Company classifies those securities in Level 3.

Loans

For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values for certain mortgage loans (e.g., one-to-four family residential), credit card loans, and other consumer loans are based on quoted market prices of similar loans sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. Fair values for other loans (e.g., commercial and agricultural loans) are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values for non-performing loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable.

Loans Held for Sale

The carrying value of loans held for sale generally approximates fair value based on the short-term nature of the assets. If management identifies a loan held for sale that will ultimately sell at a value less than its carrying value, it is recorded at the estimated value.

Loan Servicing Rights

Fair value is based on market prices for comparable loan servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income.

96

Other Real Estate Owned

Loans on which the underlying collateral has been repossessed are adjusted to fair value upon transfer to other real estate owned. Subsequently, other real estate owned is carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral, or management’s estimation of the value of the collateral. Due to the significance of the unobservable inputs, all other real estate owned are classified as Level 3.

Deposits

The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts of variable-rate, fixed-term money market accounts and certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Other Borrowings

The carrying amounts of federal funds purchased, other borrowings and other short-term borrowings maturing within ninety days approximate their fair values. Fair values of other short-term borrowings are estimated using discounted cash flow analyses based on current market rates for similar types of borrowing arrangements.

Advances from FHLB

Current market rates for debt with similar terms and remaining maturities are used to estimate fair value of existing debt. Fair values are estimated using discounted cash flow analyses based on current market rates for similar types of borrowing arrangements.

Subordinated Debentures

The carrying amounts approximate fair value.

Accrued Interest

The carrying amounts approximate fair value.

Commitments to Extend Credit and Standby Letters of Credit

As of December 31, 2017 and 2016, the carrying and fair values of the commitment to extend credit and standby letters of credit are not considered significant.

Assets Measured at Fair Value on a Nonrecurring Basis

Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, they are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following table presents the financial instruments carried on the consolidated balance sheet by caption and by level in the fair value hierarchy for which a nonrecurring change in fair value has been recorded:

	Level 1 Inputs		Level 2 Inputs		Level 3 Inputs		Impairment Losses
	(dollars in thousands)
December 31, 2017
Impaired loans	$	—	$	—	$	33,002	$	1,436
Other real estate owned		—		—		4,962		905
Total assets at fair value	$	—	$	—	$	37,964	$	2,341
December 31, 2016

Other real estate owned		—		—		3,161		480
Total assets at fair value	$	—	$	—	$	23,265	$	1,816

The significant inputs used in the fair value measurements for Level 3 assets measured at fair value on a nonrecurring basis are as follows:

December 31, 2017
	Valuation Techniques	Unobservable Inputs	Range (Average)
Impaired loans	Evaluation of collateral	Estimation of value	NM*
Other real estate owned	Appraisal	Appraisal adjustment	0%-39% (14%)
December 31, 2016
	Valuation Techniques	Unobservable Inputs	Range (Average)
Impaired loans	Evaluation of collateral	Estimation of value	NM*
Other real estate owned	Appraisal	Appraisal adjustment	7%-39% (21%)

* Not Meaningful. Evaluations of the underlying assets are completed for each impaired loan with a specific reserve. The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate. Collateral

98

evaluations are reviewed and discounted as appropriate based on knowledge of the specific type of collateral. In the case of real estate, an independent appraisal may be obtained. Types of discounts considered include aging of receivables, condition of the collateral, potential market for the collateral, and estimated disposal costs. These discounts will vary from loan to loan, thus providing a range would not be meaningful.

Impaired Loans

In accordance with the provisions of the loan impairment guidance, impairment was measured for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, or discounted cash flows. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceeds the recorded investments in such loans. Impaired loans for which an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. Collateral values are estimated using Level 3 inputs based on customized discounting criteria.

Impairment amounts on impaired loans represent specific valuation allowance and write-downs during the period presented on impaired loans that were individually evaluated for impairment based on the estimated fair value of the collateral less estimated selling costs, excluding impaired loans fully charged-off.

Other Real Estate Owned

Foreclosed assets are recorded at fair value based on property appraisals, less estimated selling costs, at the date of the transfer with any impairment amount charged to the allowance for loan losses. Subsequent to the transfer, foreclosed assets are carried at the lower of cost or fair value, less estimated selling costs with changes in fair value or any impairment amount recorded in the other non-interest expense. Values are estimated using Level 3 inputs based on customized discounting criteria. The carrying value of foreclosed assets is not re-measured to fair value on a recurring basis but is subject to fair value adjustments when the carrying value exceeds the fair value, less estimated selling costs.

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

	December 31, 2017				December 31, 2016
	Carrying Amount		Fair Value		Carrying Amount		Fair Value		Input Level

ITEM 9A. CONTROLS AND PROCEDURES

Disclosures Controls and Procedures: Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2017. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2017, our disclosure controls and procedures were effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by us in the reports that we file or submit under the Exchange Act.

Changes in Internal Control Over Financial Reporting: There was no change in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended December 31, 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting

REPORT BY COUNTY BANCORP, INC.’S MANAGEMENT

ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining an effective system of internal control over financial reporting, as such term is defined in Section 13a-15(f) of the Exchange Act. The Company’s system of internal control over financial reporting is 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. There are inherent limitations in the effectiveness of any system of internal control over financial reporting, including the possibility of human error and circumvention or overriding of controls. Accordingly, even an effective system of internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Management maintains a comprehensive system of internal controls intended to ensure that transactions are executed in accordance with management’s authorization, assets are safeguarded and financial records are reliable. Management also takes steps to see that information and communication flows are effective and to monitor performance, including performance of internal control procedures.

Management assessed the Company’s systems of internal control over financial reporting as of December 31, 2017. This assessment was based on criteria for effective internal control over financial reporting described in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management believes that as of December 31, 2017, the Company maintained effective internal control over financial reporting based on those criteria.  Our auditors will not be required to formally opine on the effectiveness of our internal control over financial reporting until we are no longer an “emerging growth company” as defined in the JOBS Act as we availed ourselves of the exemptions available to us under the JOBS Act.

Exhibit 3.1

THIRD AMENDED AND RESTATED ARTICLES OF INCORPORATION

OF

COUNTY BANCORP, INC.

These Third Amended and Restated Articles of Incorporation shall supersede and replace the heretofore existing Second Amended and Restated Articles of Incorporation and all amendments thereto of County Bancorp, Inc., a Wisconsin corporation organized under Chapter 180 of the Wisconsin Statutes:

ARTICLE I NAME

The name of the Corporation is County Bancorp, Inc. (the “Corporation”).

ARTICLE II PURPOSES

The purpose for which this Corporation is organized is to engage in any lawful activity within the purposes for which corporations may be organized under the Wisconsin Business Corporation Law, Chapter 180 of the Wisconsin Statutes (hereinafter referred to as the “WBCL”).

ARTICLE III CAPITAL STOCK

The aggregate number of shares which the Corporation shall have the authority to issue is fifty million, six hundred thousand (50,600,000). The designation of each class of shares, the authorized number of shares of each class and the par value thereof per share shall be as follows:

Designation of Class of Stock	Par Value Per Share	Authorized Number of Shares
Common Stock	0.01	50,000,000
Preferred Stock
Consisting of:
Series B Nonvoting Noncumulative Perpetual Preferred Stock	0.01	15,000
Not Classified	0.01	585,000

For avoidance of doubt, there is intentionally no provision made here for: (i) “Series A” preferred stock: effective May 16, 2009, former Series A preferred stock has been extinguished, and all formerly authorized shares of Series A preferred stock have been reclassified as Preferred Stock Not Classified; or (ii) “Series C” preferred stock: effective February 23, 2016, former Series C preferred stock has been extinguished, and all formerly authorized shares of Series C preferred stock have been reclassified as Preferred Stock Not Classified.

A-1

The preferences, limitations and relative rights of shares of each class of stock shall be as follows:

Common Stock

Except as otherwise provided by law and subject to the rights of holders of any series of Preferred Stock, the holders of Common Stock shall be entitled to vote for the election of directors of the Corporation and for all other corporate purposes. Except as otherwise provided by law, upon any such vote, each holder of Common Stock shall be entitled to one vote for each share of Common Stock held of record by such shareholder. Subject to the rights of holders of any series of Preferred Stock, the holders of Common Stock shall be entitled to receive such dividends as may be declared thereon from time to time by the Board of Directors, in its discretion, out of any funds of the Corporation at the time legally available for payment of dividends on Common Stock. In the event of the voluntary or involuntary dissolution, liquidation or winding up of the Corporation, after there have been paid to or set aside for the holders of any series of Preferred Stock the full preferential amounts, if any, to which they are entitled, the holders of outstanding Common Stock shall be entitled to share ratably, according to the number of shares held by each, in the remaining assets of the Corporation available for distribution.

Preferred Stock

The Corporation’s preferred stock shall consist of (i) Series B Nonvoting Noncumulative Perpetual Preferred Stock, and (ii)  Preferred Stock Not Classified, having the terms and relative rights and preferences provided below.

Series B Nonvoting Noncumulative Perpetual Preferred Stock. This series of preferred stock shall have the following relative rights and preferences:

1. Title. The series shall be titled “Series B Nonvoting Noncumulative Perpetual Preferred Stock.”

2. Definitions. In this Section, in addition to the terms defined elsewhere herein, the term “Series B Preferred” shall mean Series B Nonvoting Noncumulative Perpetual Preferred Stock and the term “Holder” (singularly, collectively the “Holders”) shall mean a record holder of Series B Nonvoting Noncumulative Perpetual Preferred Stock.

3. Number of Shares. The Series B Preferred shall consist of fifteen thousand (15,000) shares.

4. Voting Rights. Holders of Series B Preferred shall have no voting rights except to the extent that such voting rights may not be denied under the Wisconsin Business Corporation Law.

5. No Conversion Rights. Shares of Series B Preferred shall not be convertible into or exchangeable for shares of common stock, shares of any other series of preferred stock, or any other class of capital stock of the Corporation except as provided in Paragraph 8.

6. Dividends.

(a) Holders of Series B Preferred shall be entitled to receive out of funds of the Corporation at the time legally available for such purpose, and subject to declaration thereof by the Board of Directors, dividends per share in an amount equal to the ‘‘Dividend Rate” (defined in (i), below) multiplied by the “Original Per-Share Purchase Price” (defined in (ii), below).

(i) “Dividend Rate” means the greater of (A) a percentage rate per annum which is the sum of (i) the “Prime Rate” (hereinafter defined) and (ii) one-half of one percent (0.50%). “Prime Rate” means the Prime Rate of Interest (the highest quoted base rate on corporate loans at large U.S. money center commercial banks) as published in the “Money Rates” section of the most recent Midwest Edition of The Walt Street Journal, provided that if at any time the Prime Rate of Interest is no longer so published in the Midwest Edition of The Wall Street Journal published on the business day immediately preceding any Adjustment Date (as defined below), then “Prime Rate” shall mean the interest rate announced as its Prime Rate of interest by the largest commercial bank headquartered

A-2

in the State of Wisconsin; and (B) four and 00/l00ths percent (4.00%) per annum (the “Minimum Rate”). If and at such times that the Dividend Rate under clause (A) of the preceding sentence shall exceed the Minimum Rate (or would exceed the Minimum Rate if adjusted as provided in this sentence), the Dividend Rate shall be adjusted from time to time each time there is a change in the Prime Rate (each an “Adjustment Date”).

(ii) “Original Per-Share Purchase Price” means One Thousand and 00/100 Dollars ($1,000.00).

(b) Dividends on all issued and outstanding shares of Series B Preferred shall accrue on a daily basis, initially from the date of issuance to last day of the calendar quarter next preceding the Dividend Payment Date (as hereinafter defined) and, thereafter, from the first day of each calendar quarter to and including the last day of such calendar quarter; and such dividends shall be computed on the basis of a 365 or 366-day year and actual days elapsed during the calendar quarter next preceding the Dividend Payment Date.

(c) Dividends payable with respect to Series B Preferred shall have no preference in right of payment over dividends payable with respect to Common Stock or any other class or series of the Corporation’s capital stock.

(d) Dividends payable with respect to Series B Preferred shall be noncumulative, and if a Quarterly Dividend is not declared by the Board of Directors the Holder(s) have no right to require payment thereof.

(e) Subject to declaration thereof by the Board of Directors, dividends shall be payable with respect to the Series B Preferred on a date established by the Board of Directors but not earlier than the first calendar day of each February, May, August and November and not later than the 15th calendar day of each such month (each a “Dividend Payment Date”) to Holders of record on the fifteenth (15th) day of the next preceding month, unless the Board of Directors shall establish a different record date in accordance with applicable law. Each such dividend (a “Quarterly Dividend”) shall be in an amount equal to one-fourth (1/4) of the annual dividend determined as provided in Paragraph 6(a). Each Quarterly Dividend shall relate to the calendar quarter next preceding such Dividend Payment Date.

(f) All dividends payable with respect to Series B Preferred shall be paid in cash and without interest.

7. Liquidation and Rank.

(a) In the event of a liquidation, dissolution, or winding up of the Corporation (whether voluntary or involuntary), the Holders shall be entitled to receive for each share Series B Preferred held, of out of the assets of the Corporation, whether such assets are capital or surplus of any nature, One Thousand and 00/100 Dollars ($1,000.00) and, in addition to such amount, a further amount equal to (i) any Quarterly Dividend for the preceding calendar quarter that has been declared but has not yet been paid; and (ii) the Quarterly Dividend unpaid and accumulated thereon prorated from the first day of the calendar quarter in which liquidation, dissolution, or winding up occurs to the effective date of such liquidation, dissolution, or winding up, and no more, before any payment shall be made or any assets distributed to the holders of common stock or any other class or series of the Corporation’s capital stock.

(b) If upon such liquidation, dissolution, or winding up, whether voluntary or involuntary, the assets thus distributed among the Holders shall be insufficient to permit the payment to such Holders of the full preferential amounts, then the entire assets of the Corporation to be distributed shall be distributed ratably among the Holders.

(c) In the event of any such liquidation, dissolution, or winding up of the Corporation, whether voluntary or involuntary, subject to all of the preferential rights of the Holders and all other classes or series of preferred stock on distribution or otherwise, the holders of Common Stock shall be entitled to receive ratably all of the remaining assets of the Corporation. A consolidation or merger of the Corporation with or into any other corporation or corporations shall be deemed to be a liquidation, dissolution, or winding up, within the meaning of this clause.

A-3

(d) The Series B Preferred shall rank prior to any other class or series of the Corporation’s capital stock (except that the Series B Preferred shall rank equal and pari passu to any other series of preferred stock of the Corporation that by its express terms ranks equal and pari passu to the Series B Preferred) and in no event shall the Corporation redeem, purchase, retire or otherwise acquire for any consideration, or make any payment on account of a sinking fund or other similar fund for the redemption, purchase, retirement or acquisition of any other capital stock of the Corporation, or any warrant, right or option to purchase any thereof, or make any distribution in respect thereof, directly or indirectly, whether in cash, obligations or securities of the Corporation or other property prior to the redemption of all of the shares of Series B Preferred as provided herein.

8. Conversion. Shares of Series B Preferred shall, at the election of the Holder(s) thereof, be converted into shares of Common Stock on the terms and conditions set forth in this Paragraph 8.

(a) Each Holder shall have the right, upon the occurrence of either of the events set forth in (i) and (ii), below (each a “Conversion Event”) to require the Corporation to issue, in exchange for each share of Series B Nonvoting Noncumulative Perpetual Preferred Stock surrendered thereby, that number of shares of the Corporation’s $0.01 par value common stock (“Common Stock”) as determined in accordance with Subparagraphs (g) through (i) below.

(i) The Corporation shall have failed to pay a Quarterly Dividend in the full amount as determined under Paragraph 6 within fifteen (15) calendar days of the applicable Dividend Payment Date on eight (8) separate Dividend Payment Dates (each such failure to be referred to as an “Omitted Dividend”); or

(ii) The Corporation shall pay a dividend with respect to its Common Stock or any other class or series of the Corporation’s common or preferred capital stock at any time after four (4) Omitted Dividends have occurred.

The provisions of clauses (i) and (ii), above, shall apply and a Conversion Event shall occur regardless of whether (A) such Omitted Dividends occur with respect to consecutive or non-consecutive Dividend Payment Dates and (B) having so failed to pay a Quarterly Dividend with respect to Series B Preferred, the Corporation, subsequent to the 15th calendar day referred to in (i) above, shall thereafter pay such Quarterly Dividend.

(b) The Holder(s)’ conversion right shall accrue and become exercisable (A) in the case of clause (i) of Subparagraph (a), above, on the latest date that the eighth (8th) Omitted Dividend would otherwise have been payable, or (B) in the case of clause (ii) of Subparagraph (a), above, on the date that the Corporation pays the dividend with respect to Common Stock or any other class or series of the Corporation’s capital stock (in either case, a “Conversion Right Effective Date”).

(c) A Holder shall have full conversion rights as provided by this Paragraph 8 notwithstanding that such Holder may have acquired shares of Series B Preferred, whether directly from the Corporation or from another Holder, after one or more Omitted Dividends shall have occurred.

(d) Each Holder’s conversion right must be exercised by written notice to the Corporation delivered after the Conversion Right Effective Date and before the next Quarterly Dividend is declared; if on the next Dividend Payment Date the Quarterly Dividend with respect to Series B Preferred is paid in accordance with the terms hereof, then the earliest Omitted Dividend that gave rise to the Holder’s conversion right will be disregarded. Any Holder’s failure to provide such notice within the time period specified in the preceding sentence shall constitute an irrevocable waiver of such Holder’s conversion right unless and until such time as such conversion right shall thereafter accrue based upon the next subsequent Omitted Dividend to occur.

(e) Upon exercise of a conversion right hereunder, each Holder shall be entitled to receive, upon surrender of each share of Series B Preferred in exchange therefor, that number of shares of Common Stock having an aggregate “Common Stock Value” (as defined in Subparagraph (f), below) equal to the sum of (i) the

A-4

Original Per-Share Purchase Price; (ii) any Quarterly Dividend for the preceding calendar quarter that has been declared but has not yet been paid; and (iii) the Quarterly Dividend unpaid and accumulated thereon prorated from the first day of the calendar quarter in which the Conversion Right Effective Date occurs to the issuance of such Common Stock, and no more.

(f) For purposes of determining the number of shares of Common Stock issuable upon conversion under this Paragraph 8, “Common Stock Value” is the value of one (1) share of Common Stock and is the lesser of (i) the per-share value the Common Stock as provided in Subparagraph (g), below, determined as of the Conversion Right Effective Date; and (ii) the per-share value the Common Stock as provided in Subparagraph (g), below, determined as of the latest date that the first Omitted Dividend that gave rise to the conversion right would have been payable (each a “Valuation Date”).

(g) As of each Valuation Date, the per-share value of the Common Stock shall be the most recent per-share appraised value of the Common Stock on an undiluted basis; provided, that if no appraisal was performed within the 18 months next preceding the Valuation Date, then the per-share value of the Common Stock shall be determined by multiplying (A) the ratio that the most recent (as of the applicable Valuation Date) per-share appraised value bears to per-share book value (per-share tangible equity) as of the date of such appraisal, by (B) per-share book value based on audited financial statements of the Corporation as of the year-end next preceding the year in which such Valuation Date occurs. In either case, the per-share appraised value used for this purpose shall not take into account any “minority discount” that may be reflected in such appraisal, but shall reflect the full appraised value of the Corporation. Until such time as there are no longer any shares of Series B Nonvoting Noncumulative Perpetual Preferred Stock outstanding, the Corporation shall maintain such records (including copies of all appraisals performed and copies of audited financial statements) as are necessary to make the determinations under this Subparagraph (g). Nothing in this Subparagraph (g) shall require the Corporation to secure an appraisal solely for the purpose of establishing the per-share value of the Common Stock. Further, nothing in this Subparagraph (g) shall require that the per-share value of the Common Stock be determined in an identical manner as of the two Valuation Dates.

(h) Subject to Subparagraph (i), below, if applicable, the conversion right under this Paragraph 8 shall be exercised by any Holder only as to all (100%) of the shares of Series B Preferred held by such Holder on the Conversion Right Effective Date.

(i) In all cases, if the number of shares of Common Stock issuable to any Holder upon conversion would cause such Holder to hold ten percent (l0.0%) or more of the then-issued and outstanding shares of Common Stock (on an undiluted basis, that is, without giving effect to any options or warrants to acquire Common Stock which may then be outstanding or to the issuance of Common Stock to any other Holder of Series B Preferred), then no shares of Common Stock shall be issued to such Holder upon conversion unless any required regulatory approval has been obtained; provided, however, that in lieu of seeking and obtaining such regulatory approval, such Holder may elect to convert only a portion of the Series B Preferred held thereby and shall retain record ownership of the remainder and shall have an ongoing right to exercise the conversion right hereunder with respect thereto.

(j) In the case of a conversion right which arises as a result of the payment of a dividend on the Corporation’s Common Stock, as provided in Subparagraph (a)(ii), above, the effective date of the issuance of Common Stock upon conversion shall be adjusted such that the converting Holder shall be entitled to participate fully in such Common Stock dividend as if such shares of Common Stock had been held of record by such Holder as of the record date for such Common Stock dividend.

9. Redemption. Shares of Series B Preferred shall be subject to redemption by the Corporation upon approval by the Federal Reserve Board, but otherwise at its election and in its sole and exclusive discretion, at any time upon thirty (30) days prior written notice given by the Corporation to the Holders at their address(es) set forth on the Corporation’s registration books therefore. The price per share at which such shares shall be redeemed (the “Redemption Price”) shall be One Thousand and 00/100 Dollars ($1,000.00) and, in addition to such amount, (i) the Quarterly Dividend for the next preceding calendar quarter if such Quarterly Dividend

A-5

has been declared but has not yet been paid and (ii) a pro-rata share of the Quarterly Dividend for the current calendar quarter that would be payable if such Quarterly Dividend were declared by the Board of Directors. The Redemption Price shall be payable in cash by the Corporation to the lawful Holder or Holders on the Redemption Date set forth in such notice upon tender by such Holder or Holders of a certificate or certificates evidencing such shares at the principal office of the Corporation. Dividends shall cease to accrue on the Redemption Date notwithstanding any delay by the Holder or Holders in tendering its or their certificate or certificates.

10. Restriction on Transfer. Shares of Series B Preferred may not be transferred, sold, conveyed, pledged or hypothecated (each a “Transfer”) by any Holder thereof without the prior express written consent of the Corporation, which consent shall not be unreasonably withheld, provided, that the Corporation may withhold such consent in its sole discretion (and such withholding shall be deemed not unreasonable) if any of the following conditions exist: (i) notice of redemption under Paragraph 9 has been given; (ii) such Transfer would require registration of common stock by the Corporation under federal or state securities laws; (iii) such Transfer would violate federal or state securities laws; (iv) such Transfer would cause the transferee to become an “interested stockholder” as defined in Section 180.1140(8)(a) of the Wisconsin Business Corporation Law; (v) such Transfer would cause transferee to hold sufficient shares to be subject to prior banking regulatory approval and such approval has not been obtained; or (vi) such Transfer would cause fewer than 500 shares of Series B Preferred to be held or record or beneficially by a single individual or entity.

Preferred Stock – Not Classified. Shares of other Preferred Stock may be issued from time to time in one or more series in any manner permitted by law pursuant to a resolution or resolutions adopted by the Board of Directors under authority hereby vested in it, each such series to be appropriately designated, prior to the issuance of any shares thereof, by some distinguishing letter, number or title. Prior to the issue of any shares of a series so established or to be established, the Board of Directors shall have full authority permitted by law and is hereby expressly empowered to fix, by resolution or resolutions, the relative rights and preferences of the shares of such series, including without limitation: (1) the number of shares to constitute each such series, and the designation of each such series; (2) the dividend rate of each such series, the conditions and dates upon which such dividends shall be payable, the relationship which such dividends shall bear to the dividends payable on any other class or classes or on any other series of any class or classes of stock, and whether such dividends shall be cumulative, noncumulative or partially cumulative; (3) whether the shares of each such series shall be subject to redemption by the Corporation and if made subject to such redemption, the times, prices and other terms and conditions of such redemption; (4) whether or not the securities of the Corporation, including shares of any other class, classes or series of any other class or classes of stock of the Corporation, or any debt securities of the Corporation, and, if provision be made for conversion or exchange, the times, prices, rates of exchange, adjustments, and other terms and conditions of such conversion or exchange; (5) the rights of the holders of the shares of each such series upon the dissolution of, or upon the distribution of the assets of, the Corporation; and (6) the extent to which the shares of each such series shall have voting rights and the manner in which such voting rights may be exercised and any restrictions or limitations on such voting rights.

ARTICLE IV PREEMPTIVE RIGHTS

No shareholder of the Corporation shall have any preemptive or other subscription rights nor be entitled, as of right, to purchase or subscribe for any part of the unissued or treasury stock of this Corporation or of any additional stock issued by reason of any increase in authorized capital stock of this Corporation or other securities, whether or not convertible into stock of the Corporation.

ARTICLE V BOARD OF DIRECTORS

The authorized number of directors of the Corporation which shall constitute the entire Board of Directors shall be such as from time to time shall be fixed by the Bylaws or determined by a majority of the then authorized number of directors, but in no case shall the authorized number of directors be less than ten (10). The directors shall be divided with respect to the time for which they severally hold office into three (3) classes, as nearly equal in number as possible, as determined by the Board of Directors, with the members of each class to hold office until their successors have been elected and qualified, or until their earlier resignation or removal.

A-6

ARTICLE VI SHAREHOLDER ACTIONS

The Bylaws may provide that any action required or permitted by the WBCL to be taken at a shareholders’ meeting to be taken without a meeting by shareholders who would be entitled to vote at a meeting holding shares with voting power sufficient to cast not less than the minimum number of votes that would be necessary to authorize or take the action at a meeting at which all shares entitled to vote were present and voted.

ARTICLE VII STATUTORY ELECTION

By virtue of this Article VII and pursuant to Section 180.1143(1) of the WBCL, the Corporation elects to be subject to the provisions of Sections 180.1140 to 180.1144 of the WBCL, and such provisions shall apply to a business combination of the Corporation with an interested stockholder, as said terms are defined in the WBCL.

ARTICLE VIII LIABILITY OF DIRECTORS AND OFFICERS

To the fullest extent permitted by the WBCL, as the same exists or may hereafter be amended, no person who is or was an officer or director of the Corporation shall be personally liable to the Corporation or its shareholders for damages, settlements, fees, fines, penalties, or other monetary liabilities arising from a breach of, or failure to perform, any duty arising solely out of his or her status as an officer or director. Any amendment or repeal of this Article VIII (or of the applicable provisions of the WBCL) shall not adversely affect the rights of any officer or director hereunder (or thereunder) with respect to acts or omissions of such officer or director occurring prior to such amendment or repeal.

ARTICLE IX INDEMNIFICATION OF DIRECTORS AND OFFICERS

The Corporation shall, to the fullest extent permitted or required by Sections 180.0850 to 180.0859, inclusive, of the WBCL, including any amendments thereto (but in the case of any such amendment, only to the extent such amendment permits or requires the Corporation to provide broader indemnification rights than prior to such amendment), indemnify its Directors and Officers against any and all Liabilities, and advance any and all reasonable Expenses, incurred thereby in any Proceeding to which any such Director or Officer is a Party because he or she is or was a Director or Officer of the Corporation.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NOTE 1—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting and reporting policies of County Bancorp, Inc. and its subsidiaries conform to accounting principles generally accepted in the United States of America and to general practice within the banking industry. The following is a description of the more significant of those policies.

Nature of Business and Significant Concentrations of Credit Risk

The Company is the sole shareholder of Investors Community Bank. The Bank is the sole member of Investors Insurance Services, LLC and ABS 1, LLC, which are both Wisconsin limited liability companies. The Company commenced operations in May of 1996; the Bank commenced operations in March of 1997. ICB Investment Corp. commenced operations in 2001. In July of 2010, the Bank formed Investors Insurance Services, LLC for the sole purpose of protecting the Bank from liability risk when selling crop insurance. Selling crop insurance had historically been a business function performed within the Bank. In September of 2011, the Bank formed ABS 1, LLC, for the sole purpose of holding real estate and personal property for sale which was obtained through repossession.  In November 2015, the Company formed County Acquisition LLC for the sole purpose of acquiring Fox River Valley Bancorp, Inc., and it was subsequently dissolved in May of 2016 after the Fox River Valley acquisition was completed.  In August of 2017, the Bank dissolved ICB Investment Corp., which was a wholly-owned Nevada subsidiary, and distributed its assets to the Bank.

The Bank provides a full range of banking and related financial services, which include real estate lending, business services, and agricultural finance, to individual and corporate customers primarily located within the state of Wisconsin. The Bank’s primary source of revenue is providing loans to customers, who are predominantly engaged in dairy farming and commercial activities. Its primary deposit products are savings and term certificate accounts. The Bank is subject to competition from other financial institutions and is regulated by federal and state banking agencies and undergoes periodic examinations by those agencies.

The Company has no other significant activities other than ownership of the Bank. Note 4 discusses the types of securities that the Company invests in. Note 5 discusses the types of lending that the Company engages in.

Agricultural loans, including agricultural operating, real estate and construction loans, represented 59.7% and 60.6% of our total loan portfolio at December 31, 2017 and 2016, respectively. Commercial real estate, including commercial construction loans, represented 25.5% and 26.3% of our total loan portfolio at December 31, 2017 and 2016, respectively.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank, and the Bank’s wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company also has three wholly-owned subsidiaries, County Bancorp Statutory Trust II, County Bancorp Statutory Trust III, and Fox River Valley Capital Trust I, that are Delaware statutory trusts which have not been consolidated in accordance with accounting guidance related to variable interest entities.

Use of Estimates in Preparing Financial Statements

The preparation of consolidated financial statements in conformity with generally accepted accounting procedures of the United States (“GAAP’) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of valuation of securities available for sale, the allowance for loan losses, loan servicing rights, other real estate owned, financial instruments, and deferred tax assets. Actual results could differ from those estimates.

Business Combinations and Valuation of Loans Acquired in Business Combinations

We account for acquisitions under Financial Accounting Standards Board (“FASB”) ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. Assets acquired and liabilities assumed in a business combination are recorded at estimated fair value on their purchase date. As provided for under GAAP, management has up to 12 months following the date of the acquisition to finalize the fair values of acquired assets and assumed liabilities where it was not possible to estimate the acquisition date fair value upon consummation.

In particular, the valuation of acquired loans involves significant estimates, assumptions and judgments based on information available as of the acquisition date. Substantially all loans acquired in the transaction are evaluated either individually or in pools of loans with similar characteristics; since the estimated fair value of acquired loans includes a credit consideration, no carryover of any previously recorded allowance for loan losses is recorded at acquisition. A number of factors are considered in determining the estimated fair value of purchased loans including, among other things, the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, estimated holding periods, contractual interest rates compared to market interest rates, and net present value of cash flows expected to be received.

In determining the fair value of acquired loans, management calculates a nonaccretable difference (the credit mark component of the acquired loans) and an accretable difference (the market rate or yield component of the acquired loans). The nonaccretable difference is the difference between the undiscounted contractually required payments and the undiscounted cash flows expected to be collected in accordance with management’s determination of the fair value. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows will result in a reversal of the provision for loan losses to the extent of prior charges and then an adjustment to accretable yield and nonaccretable difference which would have a positive impact on interest income.

The accretable yield on acquired loans is the difference between the expected cash flows and the initial investment in the acquired loans. The accretable yield is recognized into earnings using the effective yield method over the term of the loans. Management separately monitors the acquired loan portfolio and periodically reviews loans contained within this portfolio against the factors and assumptions used in determining the fair value.

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and balances due from banks and federal funds sold, all of which mature within 90 days.

In the normal course of business, the Company maintains balances with correspondent banks. Accounts at each institution are insured by the Federal Deposit Insurance Corporation up to specified limits. Management believes these financial institutions have strong credit ratings and the credit risk related to these deposits is minimal.

Securities Available for Sale

Available for sale securities are carried at fair value with unrealized gains and losses excluded from earnings and reported separately in other comprehensive income (loss). The Company currently has no securities designated as trading or held-to-maturity. 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. They are included in non-interest income or expense and, when applicable, are reported as a reclassification adjustment in other comprehensive income (loss).

Declines in the fair value of individual available for sale securities below their cost that are other than temporary result in write-downs of the individual securities to their fair value. The Company monitors the investment security portfolio for impairment on an individual security basis and has a process in place to identify securities that could potentially have a credit impairment that is other than temporary. This process involves analyzing the length of time and the extent to which the fair value has been less than the amortized cost basis, the market liquidity for the security, the financial condition and near-term prospects of the issuer, expected cash flows, and the Company’s intent and ability to hold the investment for a period of time sufficient to recover the temporary impairment. A decline in value due to a credit event that is considered other than temporary is recorded as a loss in non-interest income.

Federal Home Loan Bank Stock

The Bank, as a member of the Federal Home Loan Bank of Chicago (“FHLB”), is required to maintain an investment in the capital stock of the FHLB based on the level of borrowings and other factors, and may invest additional amounts. Based on the redemption provisions of the FHLB, the stock has no quoted market value and is carried at cost. It is periodically evaluated by management for impairment. Because it is viewed as a long term investment, impairment is based on ultimate recovery of par value. Both stock and cash dividends are reported as income.

Loans Held for Sale

Loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value. Gains and losses on loan sales (sale proceeds minus carrying value) are recorded in non-interest income and direct loan origination costs and fees are deferred at origination of the loan and are recognized in non-interest income upon sale of the loan.

Loans

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balances adjusted for unearned income and the allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, non-refundable fees and direct loan origination costs on real estate and commercial loans are, in the opinion of management, insignificant and recognized as current income and are not accounted for as an adjustment of yield of the related loan categories.

The accrual of interest on mortgage and commercial loans is discontinued at the time the principal and interest is 90 days delinquent unless the credit is well-secured and in the process of collection.  Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful.

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

Allowance for Loan Losses

The allowance for loan losses (hereinafter referred to as “allowance”) is an estimate of loan losses inherent in the Company’s loan portfolio. The allowance is established through a provision for loan losses which is charged to expense. Additions to the allowance are expected to maintain the adequacy of the total allowance after loan losses and loan growth. Loan losses are charged off against the allowance when the Company determines the loan balance to be uncollectible. Cash received on previously charged off amounts is recorded as a recovery to the allowance.

The allowance consists of two primary components, general reserves and specific reserves related to impaired loans. The general component covers non-impaired loans and is based on historical losses adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on a weighted average of the actual loss history experienced by the Company over the most recent four years. The Company places more emphasis, or weight, on the more current quarters in the loss history period. This actual loss experience is adjusted for economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. These factors are inherently subjective and are driven by the repayment risk associated with each portfolio segment.

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is generally measured on a loan by loan basis by either the present value of expected future cash flows discounted at the loans’ effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

Under certain circumstances, the Company will provide borrowers relief through loan restructurings. A restructuring of debt constitutes a troubled debt restructuring (“TDR”) if the Company for economic or legal reasons related to the borrower’s financial difficulties grants a concession to the borrower that it would not otherwise consider. Restructured loans typically present an elevated level of credit risk as the borrowers are not able to perform according to the original contractual terms. Loans that are reported as TDRs are considered impaired and measured for impairment as described above. TDR concessions can include reduction of interest rates, extension of maturity dates, forgiveness of principal or interest due, or acceptance of other assets in full or partial satisfaction of the debt. Restructured loans can involve loans remaining on nonaccrual, moving to nonaccrual, or continuing on accrual status, depending on the individual facts and circumstances of the borrower. Nonaccrual restructured loans are included and treated with other nonaccrual loans.

Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment disclosures, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower.

The Company maintains a separate general valuation allowance for each portfolio segment. These portfolio segments include agricultural, commercial, commercial real estate, residential real estate, and installment and consumer other with risk characteristics described as follows:

Agricultural: Agricultural loans generally possess a lower inherent risk of loss than real estate portfolio segments because these loans are generally underwritten to existing cash flows of operating businesses. Debt coverage is provided by business cash flows and economic trends influenced by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans.

Commercial: Commercial loans generally possess a lower inherent risk of loss than real estate portfolio segments because these loans are generally underwritten to existing cash flows of operating businesses. Debt coverage is provided by business cash flows, and economic trends influenced by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans.

Commercial Real Estate: Commercial real estate loans, including land and construction, generally possess a higher inherent risk of loss than other real estate portfolio segments. Adverse economic developments or an overbuilt market impact commercial real estate projects and may result in troubled loans. Trends in vacancy rates of commercial properties impact the credit quality of these loans. High vacancy rates reduce operating revenues and the ability for the properties to produce sufficient cash flow to service debt obligations.

Residential Real Estate: The degree of risk in residential mortgage and home equity lending depends primarily on the loan amount in relation to collateral value, the interest rate and the borrower’s ability to repay in an orderly fashion. These loans generally possess a lower inherent risk of loss than other real estate portfolio segments. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers’ capacity to repay their obligations may be deteriorating.

Installment and Consumer Other: The installment and consumer other loan portfolio is usually comprised of a large number of small loans. Most loans are made directly for consumer purchases. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate the borrowers’ capacity to repay their obligations may be deteriorating.

Although management believes the allowance to be adequate, ultimate losses may vary from its estimates. At least quarterly, the board of directors reviews the adequacy of the allowance, including consideration of the relevant risks in the portfolio, current economic conditions and other factors. If the board of directors and management determine that changes are warranted based on those reviews, the allowance is adjusted. In addition, the Company’s primary regulator reviews the adequacy of the allowance. The regulatory agencies may require additions to the allowance based on their judgment about information available at the time of their examinations.

Bank Premises and Equipment

Land is carried at cost. Bank premises and equipment are carried at cost, less accumulated depreciation. Depreciation is computed on the straight line method. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any recognized gain or loss is reflected in income for the period. The cost of maintenance and repairs is charged to expense as incurred; significant renewals and improvements are capitalized and a deduction is made from the property accounts for retirements of capitalized renewals or improvements. Gains and losses on dispositions are included in current operations.

Off-Balance Sheet Credit Related Financial Instruments

In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded. The Company maintains a separate allowance for off-balance sheet commitments. Management estimates anticipated losses using historical data and utilization assumptions. The allowance for off-balance sheet commitments is included in other liabilities.

Impairment of Long-Lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of carrying amount and the fair value less costs to sell.

Loan Servicing Rights

Servicing assets are recognized as separate assets when rights are acquired through the sale of financial assets. Servicing rights resulting from the sale or securitization of loans originated by the Company are initially measured at fair value at the date of transfer. The Company subsequently measures each class of servicing asset using the amortization method. Under the amortization method, servicing rights are amortized in proportion to and over the period of estimated net servicing income. The amortized assets are assessed for impairment or increased obligation based on fair value at each reporting date.

Fair value is based on market prices for comparable servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. These variables change from quarter-to-quarter as market conditions and projected interest rates change, and may have an adverse impact on the value of the servicing right and may result in a reduction to non-interest income.

Servicing assets measured using the amortization method are evaluated and measured for impairment. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the carrying amount of the servicing assets for that tranche. The valuation allowance is adjusted to reflect changes in the measurement of impairment after the initial measure of the impairment.

Changes in the valuation allowances are reported with loan servicing fees on the income statement. Fair value in excess of the carrying amount of servicing assets for that stratum is not recognized.

Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of loan servicing rights is netted against loan servicing fee income.

Other Real Estate Owned

Land purchased by the Bank that is held for sale is recorded at the lower of cost or market value.

Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value at the date of foreclosure less estimated costs to sell, 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 non-interest expense.

Impairment losses on assets to be held and used are measured at the amount by which the carrying amount of a property exceeds its fair value. The evaluation of impairment is inherently subjective and requires estimates that are susceptible to significant revisions as more information becomes available. Due to potential changes in conditions, it is at least reasonably possible that changes in fair values will occur in the near term and that such changes could materially affect the amounts reported in the Company’s financial statements. Costs of significant asset improvements are capitalized, whereas costs relating to holding assets are expensed. Revenue and expenses from operations and changes in the valuation allowance are included in other non-interest expense.

Cash Surrender Value of Bank Owned Life Insurance

The Company has purchased life insurance policies on certain key executives. Bank owned life insurance is recorded at its cash surrender value, or the amount that can be realized, if lower.

Goodwill and Core Deposit Intangible

Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired and is included as an asset on the consolidated balance sheets. Goodwill is not amortized but is subject to impairment tests on at least an annual basis. Core deposit intangible represents the value of the acquired customer core deposit bases and is included in as an asset on the consolidated balance sheets. The core deposit intangible has an estimated finite life, is amortized on an accelerated basis over a 66-month period, and is subject to periodic impairment evaluation.

Management will periodically review the carrying value of its long-lived and intangible assets to determine if any impairment has occurred or whether changes in circumstances have occurred that would require a revision to the remaining useful life, in which case an impairment charge would be recorded as an expense in the period of impairment. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. Goodwill was $5.0 million at December 31, 2017 and 2016.  There was no impairment charge to goodwill or core deposit intangible related to the Fox River Valley acquisition at December 31, 2017.  The net book value of core deposit intangible was $0.9 million and $1.4 million at December 31, 2017 and December 31, 2016, respectively.  Goodwill and core deposit intangible are included on the consolidated balance sheets.

Income Taxes

The Company accounts for income taxes in accordance with income tax accounting guidance, which sets out a consistent framework to determine the appropriate level of tax reserves to maintain for uncertain tax positions.

The 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 determined based on the tax effects of the temporary 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%; 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% 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 the some portion or all of the deferred tax asset will not be realized.  For the year ended December 31, 2017, the value of our net deferred tax asset was reduced by $0.9 million and recorded as additional income tax expense as a result of the Tax Act that was enacted on December 22, 2017.

The Company files income taxes returns in the U.S. federal jurisdiction and in the state of Wisconsin. The Company is no longer subject to U.S. federal or state income tax examinations by tax authorities for years before 2014.

The Company recognizes interest and penalties on income taxes, if any, as a component of other non-interest expense.

Comprehensive Income

Recognized revenue, expenses, gains, and losses are included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on securities available for sale, are reported as a separate component of the equity section of the consolidated balance sheet, such items, along with net income, are components of comprehensive income.

Equity Incentive Plan

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

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

Treasury Stock

Common stock shares repurchased are recorded as treasury stock at cost.

Earnings per Share

Basic earnings per share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional potential 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 outstanding stock options, and are determined using the treasury stock method.

Treasury shares are not deemed outstanding for earnings per share calculations.

Transfers of Financial Assets

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

The transfer of a participating interest in an entire financial asset must also meet the definition of a participating interest. A participating interest in a financial asset has all of the following characteristics: (1) from the date of transfer, it must represent a proportionate (pro rata) ownership interest in the financial asset, (2) from the date of transfer, all cash flows received, except any cash flows allocated as any compensation for servicing or other services performed, must be divided proportionately among participating interest holders in the amount equal to their share ownership, (3) the rights of each participating interest holder must have the same priority, and (4) no party has the right to pledge or exchange the entire financial asset unless all participating interest holders agree to do so.

Advertising Costs

Advertising costs are expensed as incurred.

Fair Value of Financial Instruments

Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 20. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect the estimates.

Segments

The Company’s operations consist of one segment, community banking.  The operating results of this segment are regularly reviewed by management to make decisions about resource allocations and to assess performance.  Selected information is not presented separately for the Company's reportable segment, as there is no material difference between that information and the corresponding information in the consolidated financial statements.

New Accounting Pronouncements

In November 2015, FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes. This ASU requires entities to present deferred tax assets (DTAs) and deferred tax liabilities (DTLs), along with any related valuation allowance, as noncurrent in a balance sheet. This ASU eliminates current guidance requiring deferred taxes for each jurisdiction to be presented as a net current asset or liability and a net noncurrent asset or liability. As a result, each jurisdiction would have one net noncurrent DTA or DTL balance. The ASU does not change the existing requirement that only permits offsetting DTAs and DTLs within a particular jurisdiction. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016, with early adoption permitted. This guidance was adopted during 2017 and did not have any material impact on the Company’s consolidated financial statements.

In January 2016, FASB issued ASU No. 2016-01, Financial Instruments: Recognition and Measurement of Financial Assets and Financial Liabilities, to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This amendment supersedes the guidance to classify equity securities with readily determinable fair values into different categories, requires equity securities to be measured at fair value with changes in the fair value recognized through net income, and simplifies the impairment assessment of equity investments without readily determinable fair values. The amendment requires public business entities that are required to disclose the fair value of financial instruments measured at amortized cost on the balance sheet to measure that fair value using the exit price notion. The amendment requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option. The amendment requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or in the accompanying notes to the financial statements. The amendment reduces diversity in current practice by clarifying that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity’s other deferred tax assets. This amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Entities should apply the amendment by means of a cumulative-effect adjustment as of the beginning of the fiscal year of adoption, with the exception of the amendment related to equity securities without readily determinable fair values, which should be applied prospectively to equity investments that exist as of the date of adoption. The Company does not have any equity securities in its portfolio; the adoption of this ASU will have no effect on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases: Amendments to the FASB Accounting Standards Codification which requires companies to recognize all leases as assets and liabilities on the consolidated balance sheet. This ASU retains a distinction between finance leases and operating leases, and the classification criteria for distinguishing between finance leases and operating leases are substantially similar to the classification criteria for distinguishing between capital leases and operating leases in the current accounting literature. The result of retaining a distinction between finance leases and operating leases is that under the lessee accounting model, the effect of leases in a consolidated statement of comprehensive income and a consolidated statement of cash flows is largely unchanged from previous GAAP. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Earlier application is permitted. The Company is currently evaluating it leases and determining the effect of this ASU will have on its financial statements and disclosures, if any.

In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation to simplify several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The amendments in this update became effective beginning January 1, 2017 and did not have a significant impact the Company’s financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses, to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date.  The amendment replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.  This amendment is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years with early adoption permitted for the fiscal year beginning after December 15, 2018, including interim periods within those fiscal years.  Entities should apply this amendment a modified-retrospective approach, through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective.  The Company has engaged a third-party software consultant to assist in developing our loss model methodology, and is currently gathering historical data.  At this time, the effect this ASU will have on its consolidated financial statements is unknown.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments, to reduce the existing diversity in practice in how certain cash receipts and payments are presented and classified on the statement of cash flows.  The amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with early adoption permitted including adoption in an interim period.  Entities should apply this amendment as of the beginning of the first reporting period in which the guidance is effective.  The adoption of this guidance is not expected to have a material impact on its consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash: A Consenus of the FASB Emerging Issues Task Force, to standardize the classification and presentation of changes to restricted cash on the statement of cash flows.  The amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with early adoption permitted including adoption in an interim period.  Entities should apply this amendment using a retrospective transition method to each period presented.  The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04 Intangibles – Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment.  This update eliminates Step 2 of the goodwill impairment test, and instead, recognizes an impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value not to exceed the total amount of goodwill allocated.  The Company early adopted this amendment effective January 1, 2017 for its goodwill impairment analysis.  The result of this amendment had no impact on the Company since its goodwill is not impaired as of December 31, 2017.

In March 2017, the FASB issued updated guidance codified within ASU No. 2017-08, Receivables – Nonrefundable Fees and Other Costs, which is intended to enhance the accounting for the amortization of premiums for purchased callable debt securities. The amendment is effective for fiscal years beginning after December 15, 2018, with early adoption permitted including adoption in an interim period. The Company is currently evaluating the effects this ASU will have on its consolidated financial statements.

In May 2017, the FASB issued updated guidance codified within ASU No. 2017-09, Compensation – Stock Compensation to provide clarity and reduce the diversity in practice and cost and complexity of applying the guidance when there is a change of terms condition of share-based awards. The amendment is effective for fiscal years beginning after December 15, 2017, with early adoption permitted including adoption in an interim period. The adoption of this ASU is not expected to have a significant impact on the Company’s consolidated financial because modification to share-based awards are rarely made.

In September 2017, the FASB issued updated guidance codified within ASU No. 2017-13, Revenue Recognition, Revenue from Contracts with Customers, Leases (Topic 840), and Leases (Topic 842) to clarify the amendment to the SEC paragraphs pursuant to the staff announcement on July 20, 2017 and update ASU No. 2016-20 Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers which was an update to ASU 2014-09 Revenue from Contracts with Customers, is the culmination of efforts by the FASB and the International Accounting Standards Board to develop a common revenue standard for GAAP and International Financial Reporting Standards. ASU 2014-09 supersedes Topic 605—Revenue Recognition and most industry-specific guidance. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those good or services. The guidance in ASU 2014-09 describes a 5-step process entities can apply to achieve the core principle or revenue recognition and requires disclosures sufficient to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers and the significant judgments used in determining that information. The amendments in ASU 2016-20 narrow the aspects of the guidance issued within ASU 2014-09 and are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period and early application is not allowed. The Company is currently cataloging revenue streams and reviewing current policies and practices to identify differences under this ASU.  The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which requires companies to reclassify the stranded effects in other comprehensive income to retained earnings as a result of the change in the tax rates under the Tax Cuts and Jobs Act (the 2017 Tax Act”).  The amendment is effective for fiscal years beginning after December 15, 2018, with early adoption permitted including adoption in an interim period.  The Company plans to early adopt this amendment during the first quarter of 2018 and will include the impact of the reclassification from other comprehensive income to retained earnings is included in the Statement of Changes in Shareholders’ Equity.

ACQUISITIONS

NOTE 2—ACQUISITION

On May 13, 2016, the Company completed its acquisition of Fox River Valley, a Wisconsin corporation, pursuant to the Agreement and Plan of Merger dated November 19, 2015 (the “Merger Agreement”) by and among the Company, County Acquisition LLC, a wholly-owned subsidiary of the Company, and Fox River Valley, whereby the Company acquired Fox River Valley and its wholly-owned bank subsidiary, The Business Bank, through the merger of Fox River Valley into County Acquisition LLC (which subsequently dissolved) and the merger of The Business Bank into Investors Community Bank.

The purpose of the acquisition was for strategic reasons beneficial to the Company. The acquisition is consistent with its growth plans to expand into the markets of Appleton and Green Bay, Wisconsin and diversify its loan portfolio to decrease its agricultural concentration.  The Company believes it is well-positioned to achieve stronger financial performance and enhance shareholder value through synergies of the combined operations.

Under the terms of the Merger Agreement, the Company acquired Fox River Valley for aggregate consideration of approximately $28.7 million which was comprised of $14.45 million in cash and 712,830 shares of the Company’s common stock valued at $20 per share on May 13, 2016.  The system integration was completed, and the two branches of The Business Bank opened on May 16, 2016 as branches of Investors Community Bank.

The Company accounted for the transaction under the acquisition method of accounting under FASB Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, and thus, the financial position and results of operations of Fox River Valley prior to the closing date were not included in the accompanying consolidated financial statements.  The accounting required assets purchased and liabilities assumed to be recorded at their respective fair values at the date of acquisition. The Company determined the fair value with the assistance of third party valuations, appraisals, and third party advisors.  The estimated fair values were subject to refinement as additional information relative to the closing date fair values became available through the measurement period of approximately one year from consummation.

During the year ended December 31, 2016, the Company incurred $2.6 million of merger related costs which are included in the consolidated statement of operations in other non-interest expense.

The fair value of the assets acquired and liabilities assumed on May 13, 2016 were as follows:

	As recorded by Fox River Valley		Fair value adjustment			As recorded by the Company
	(dollars in thousands)
Cash, cash equivalents and securities available for sale	$	77,117	$	(484	)	$	76,633

The unrealized loss on the investments at December 31, 2017 and 2016 was due to normal fluctuations and pricing inefficiencies. The contractual terms of the investments do not permit the issuers to settle the securities at a price less than the amortized cost basis of the investment. Because the Company does not intend to sell the investments and it is not more-likely-than-not that the Company will be required to sell the investments before recovery of the amortized cost basis, which may be maturity, the Company did not consider these investments to be other-than-temporarily impaired at December 31, 2017 and 2016.

Other-Than-Temporary Impairment

Upon acquisition of a security, the Company decides whether it is within the scope of the accounting guidance for beneficial interests in securitized financial assets or will be evaluated for impairment under the accounting guidance for investments in debt and equity securities.

The accounting guidance for beneficial interests in securitized financial assets provides incremental impairment guidance for a subset of the debt securities within the scope of the guidance for investments in debt and equity securities. For securities where the security is a beneficial interest in securitized financial assets, the Company uses the beneficial interest in securitized financial asset impairment model. For securities where the security is not a beneficial interest in securitized financial assets, the Company uses debt and equity securities impairment model.

The Company routinely conducts periodic reviews to identify and evaluate each investment security to determine whether an other-than-temporary impairment has occurred. Economic models are used to determine whether an other-than-temporary impairment has occurred on these securities. While all securities are considered, the securities primarily impacted by other-than-temporary impairment testing are private-label mortgage-backed securities. For each private-label mortgage-backed security in the investment portfolio (including but not limited to those whose fair value is less than their amortized cost basis) an extensive, regular review is conducted to determine if an other-than-temporary impairment has occurred. Various inputs to the economic models are used to determine if an unrealized loss is other-than-temporary. The most significant inputs are the default rate and the severity of the decline in value. Other inputs may include the actual collateral attributes, which include geographic concentrations, credit ratings, and other performance indicators of the underlying assets.

There were no securities with material unrealized losses existing longer than 12 months, and no securities with unrealized losses which management believed were other-than-temporarily impaired, at December 31, 2017 or 2016.

At December 31, 2017, 127 debt securities had unrealized losses with aggregate depreciation of 1.27% from the Company’s amortized cost basis. At December 31, 2016, 117 debt securities had unrealized losses with aggregate depreciation of 1.25% from the Company’s amortized cost basis.  These unrealized losses related principally to Government National Mortgage Association mortgage-backed and municipal debt securities. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and industry analysts’ reports. As management has the intent and ability to hold debt securities until maturity for the foreseeable future if classified as available for sale, the decline is not deemed to be other-than-temporary.

Troubled Debt Restructurings

The Company had allocated $0.9 million and $0.5 million of specific reserves to customers whose loan terms have been modified in troubled debt restructurings at December 31, 2017 and 2016, respectively. The Company had no additional lending commitments at December 31, 2017 and 2016 to customers with outstanding loans that are classified as troubled debt restructurings.

A TDR on nonaccrual status is classified as a nonaccrual loan until evaluation supports reasonable assurance of repayment and of performance according to the modified terms of the loan. Once this assurance is reached, the TDR is classified as a restructured loan.  At December 31, 2017, there were $13.4 million TDR loans, of which $4.4 million were classified as nonaccrual and $9.0 million were classified as restructured and accruing, and there were $0.1 million unfunded commitments on these loans. At December 31, 2016, there were $14.0 million TDR loans, of which $9.7 million were classified as nonaccrual and $4.3 million were classified as restructured and accruing. There were $35,000 unfunded commitments on these loans.      

The following table provides the number of loans modified in a troubled debt restructuring investment by class for the year ended December 31, 2017 and 2016:

Credit Quality Indicators

The Company categorizes loans into risk categories based on relevant information about the ability of the borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. The Company analyzes agricultural, commercial, and commercial real estate loans individually by classifying the credits as to credit risk. The process of analyzing loans for changes in risk rating is ongoing through routine monitoring of the portfolio and annual internal credit reviews for credits with total exposure in excess of $0.3 million. The Company uses the following definitions for credit risk ratings:

Sound. Credits classified as sound show very good probability of ongoing ability to meet and/or exceed obligations.

Acceptable. Credits classified as acceptable show a good probability of ongoing ability to meet and/or exceed obligations.

Satisfactory. Credits classified as satisfactory show an average probability of ongoing ability to meet and/or exceed obligations.

Low Satisfactory. Credits classified as low satisfactory may have more inconsistent earnings, but have a fair probability of ongoing ability to meet and/or exceed obligations.

Watch. Credits classified as watch show some questionable probability of ongoing ability to meet and/or exceed obligations.

Special Mention. Credits classified as special mention show potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loans or of the institution’s credit position at some future date.

Substandard – Performing.Credits classified as substandard – performing generally have well-defined weaknesses. Collateral coverage is adequate and the loans are not considered impaired.  Payments are being made and the loans are on accrual status.

Substandard - Impaired.Credits classified as substandard generally have well-defined weaknesses that jeopardize the repayment of the debt. They have a distinct possibility that a loss will be sustained if the deficiencies are not corrected.  Loans are considered impaired.  Loans are either exhibiting signs of delinquency, are on non-accrual or are identified as a TDR.

Doubtful. Credits classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable.

The Company categorizes residential real estate, installment and consumer other loans as satisfactory at the time of origination based on information obtained as to the ability of the borrower(s) to service their debt, such as current financial information, employment status and history, historical payment experience, credit scores and type and amount of collateral among other factors. The Company updates relevant information on these types of loans at the time of refinance, troubled debt restructuring or other indications of financial difficulty, downgrading as needed using the same category descriptions as for agricultural, commercial, and commercial real estate loans. In addition, the Company further considers current payment status as an indicator of which risk category to assign the borrower.

The greater the level of deteriorated risk as indicated by a loan’s assigned risk category, the greater the likelihood a loss will occur in the future. If the loan is impaired then the loan loss reserves for the loan are recorded at the loss level of impairment. If the loan is not impaired, then its loan loss reserves are determined by the application of a loss rate that increases with risk in accordance with the allowance for loan loss analysis.

Based on the most recent analysis performed by management, the risk category of loans by class of loans is as follows:  

	As of December 31, 2017
	Sound/ Acceptable/ Satisfactory/ Low Satisfactory		Watch		Special Mention		Substandard Performing		Substandard Impaired		Total Loans

LOAN SERVICING RIGHTS

NOTE 7—LOAN SERVICING RIGHTS

Loans serviced for others are not included in the accompanying consolidated balance sheets. The risks inherent in servicing assets relate primarily to changes in prepayments that result from shifts in interest rates. The unpaid principal balances of mortgage and other loans serviced for others were approximately $600.7 million and $577.0 million at December 31, 2017 and 2016, respectively.

The following summarizes servicing rights capitalized and amortized, along with the aggregate activity in related valuation allowances:

Goodwill And Intangible Assets Disclosure [Abstract]

GOODWILL AND CORE DEPOSIT INTANGIBLE

NOTE 8 – GOODWILL AND CORE DEPOSIT INTANGIBLE

The excess of the purchase price in an acquisition over the fair value of net assets acquired consists primarily of goodwill and the core deposit intangible. Goodwill is not amortized but is instead subject to impairment tests on at least an annual basis. Core deposit intangible, which arose from value ascribed to the deposit base of a bank acquired, has an estimated finite life and is amortized on an accelerated basis to expense over a 66-month period.

Management will periodically review the carrying value of its long-lived and intangible assets to determine if any impairment has occurred, in which case an impairment charge would be recorded as an expense in the period of impairment, or whether changes in circumstances have occurred that would require a revision to the remaining useful life which would impact expense prospectively. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. There was no impairment charge to goodwill or core deposit intangible at December 31, 2017 or 2016.  

Goodwill:  Goodwill resulted from the acquisition of Fox River Valley on May 13, 2016.  The carrying amount of goodwill was $5.0 million at December 31, 2017 and 2016. See Note 2 for additional information on the acquisition.

Core deposit intangible:  Core deposit intangible, primarily related to acquired customer relationships, is amortized over its estimated finite life.  The core deposit intangible related to the Fox River Valley acquisition had a gross carrying amount of $1.8 million. Amortization on core deposit intangible was $882 and $360 thousand for the year ended December 31, 2017 and 2016, respectively. See Note 2 for additional information on the acquisition.

The terms of security agreements with the FHLB require the Bank to pledge collateral for its borrowings. The collateral consists of qualifying first mortgage loans, certain securities available for sale, and stock of the FHLB.

The Bank had no irrevocable letters of credit with the FHLB as of December 31, 2017 and 2016.

As of December 31, 2017 and 2016, the Bank also had a $50.0 million line-of-credit available with the Federal Reserve Bank of Chicago.  Borrowings under this line of credit are limited by the amount of securities pledged by the Bank as collateral, which totaled $8.6 million and $11.3 million at December 31, 2017 and 2016, respectively.  There were no outstanding advances included in other borrowings at December 31, 2017 or 2016, respectively.  

On September 14, 2017, the Company entered into a credit agreement with U.S. Bank, National Association for a $15.0 million revolving line-of-credit with an interest rate equal to the one-month LIBOR rate plus 2.25%.  The line also bears a non-usage fee of 0.275% per annum.  The non-usage fee for year ended December 31, 2017 was $5 thousand.  The line did not have an outstanding balance as of December 31, 2017, and was unused during the year.

Other borrowings are borrowings as a result of sold loans that do not qualify for sale accounting. These agreements are recorded as financing transactions as the Bank maintains effective control over the transferred loans. The dollar amount of the loans underlying the sale agreements continues to be carried in the Bank’s loan portfolio, and the transfer is reported as a secured borrowing with pledge of collateral.  At December 31, 2017 and 2016, the amounts of these borrowings were $1.3 million and $2.0 million, respectively.

Also included in other borrowings is the capital lease for our full service banking location in Appleton, Wisconsin that was assumed in connection with our merger of Fox River Valley.  Under the terms of the current triple-net lease the Company is obligated to pay monthly rent of $15 thousand, and the lease term expires in April 2019.  As of December 31, 2017, liability remaining under the capital lease was $41 thousand, and the amortization related to the lease was $148 thousand and was included in other non-interest expense.  As of December 31, 2016, liability remaining under the capital lease was $189 thousand, and the amortization related to the lease was $85 thousand and was included in other non-interest expense.

SUBORDINATED DEBENTURES AND SBLF PREFERRED STOCK

NOTE 12—SUBORDINATED DEBENTURES AND SBLF PREFERRED STOCK

In September 2005 and June 2006, the Company formed wholly owned subsidiary business trusts, County Bancorp Statutory Trust II (“Trust II”) and County Bancorp Statutory Trust III (“Trust III”) (together, the “Trusts”), which are both Delaware statutory trusts, for the purpose of issuing capital securities which qualify as Tier 1 capital of the Company. Trust II issued at par $6.0 million of floating rate capital securities in an exempt offering. The capital securities are nonvoting, mandatorily redeemable in 2035, and guaranteed by the Company. Trust III issued at par $6.0 million of floating rate capital securities in an exempt offering. The capital securities are nonvoting, mandatorily redeemable in 2036, and guaranteed by the Company.

The capital securities carry an interest rate identical to that of the related debentures. For Trust II, holders of capital securities are entitled to receive cumulative cash distributions at a rate of 6.1% through September 2015, and a rate based on the three month LIBOR plus 1.53% thereafter through maturity, which was 3.12% as of December 31, 2017. For Trust III, holders of capital securities are entitled to receive cumulative cash distributions at a rate based on the three month LIBOR plus 1.69% through maturity, which was 3.28% as of December 31, 2017.

The distribution rate payable on the capital securities is cumulative and payable quarterly in arrears. The Company has the right, subject to events of default, to defer payments of interest on the debentures at any time by extending the interest payment period for a period not exceeding 20 consecutive quarters with respect to each deferral period, provided that no extension period may extend beyond the redemption or maturity dates of the debentures. The capital securities are subject to mandatory redemption upon payment of the debentures. Trust II and III mature on September 15, 2035 and June 15, 2036, respectively, may be called not earlier than September 15, 2015 and June 15, 2016, respectively, if certain conditions were met, or at any time within 180 days following the occurrence and continuation of certain changes in either tax treatment or the capital treatment of Trust II and Trust III, the debentures, or the capital securities. If the debentures are redeemed before they mature, the redemption price will be the principal amount plus any accrued but unpaid interest. The Company has the right to terminate Trust II and Trust III and cause the debentures to be distributed to the holders of the capital securities in liquidation of such Trusts.

The Company owns all of the outstanding common securities of Trust II and Trust III. The Trusts used the proceeds from the issuance of their capital securities to buy floating rate junior subordinated deferrable interest debentures (“debentures”) issued by the Company. These debentures are the Trusts’ only assets, and interest payments from these debentures finance the distributions paid on the capital securities. These debentures are unsecured, rank junior, and are subordinate in the right of payment to all senior debt of the Company.

The capital securities of Trust II and Trust III have been structured to qualify as Tier 1 capital for regulatory purposes. However, the securities cannot be used to constitute more than 25 percent of the Company’s “core” Tier 1 capital according to regulatory requirements. The Company utilized the proceeds of the Trust II issuances for general corporate purposes and Trust III issuances to redeem the securities of County Bancorp Statutory Trust I.

In connection with the merger with Fox River Valley, the Company also acquired Fox River Valley’s wholly-owned subsidiary Fox River Valley Capital Trust I, a Delaware statutory trust (the “FRV Trust I”), which issued capital securities that qualify for Tier II capital of the Company.  The Company assumed the $3.6 million of floating rate, junior subordinated debentures, of which the Company owns $0.1 million. The debentures are non-voting, mandatorily redeemable in 2033 and guaranteed by the Company.

The distribution rate payable on the debentures is cumulative and payable quarterly in arrears. The Company has the right, subject to events of default, to defer payments of interest on the debentures at any time by extending the interest payment period not exceeding 20 consecutive quarters with respect to each deferral period, provided that no extension period may extend beyond the redemption or maturity date of the debentures. Interest is current through the most recent due date of December 15, 2017.

The FRV Trust I may redeem some or all of the capital securities, at par, with 30 days advance notice, on or after November 30, 2008, but only on May 30 or November 30 of any given year, and only in a minimum amount of $500,000 and in increments of $10,000 thereafter, or the full amount of the capital securities. The FRV Trust I may redeem all of the capital securities at any time upon the occurrence and during the continuation of a Tax Event, an Investment Company Event or a Capital Treatment Event (each as defined in the trust agreement for the FRV Trust I), at any time within 90 days following such event.

The FRV Trust I debentures carry an interest rate equal to 5-year LIBOR plus 3.40%, which resets every five years. The current rate is equal to 4.855% through November 30, 2018. Interest payments are due quarterly.

The Small Business Lending Fund (SBLF) preferred stock of the Company qualified as Tier 1 capital and accrued noncumulative dividends, payable quarterly, on each January 1, April 1, July 1 and October 1. The dividend rate, as a percentage of the liquidation amount, fluctuated on a quarterly basis during the first 10 quarters during which the preferred stock was outstanding, based upon changes in the level of “Qualified Small Business Lending”, by the Company’s subsidiary bank. The dividend rate was based upon the percentage change in QSBL between each dividend period and the baseline QSBL level, as determined in accordance with the Purchase Agreement.

Beginning with the fourth quarter of 2013, the dividend rate was fixed at an annualized 1.00% through the fourth quarter of 2015.  Such dividends were not cumulative, but the Company could only declare and pay dividends on its common stock (or any other equity securities junior to the SBLF Preferred Stock) if it had declared and paid dividends for the current dividend period on the SBLF Preferred Stock, and would be subject to other restrictions on its ability to repurchase or redeem other securities.

The Company could redeem the shares of SBLF Preferred Stock, in whole or in part, at any time at a redemption price equal to the sum of the liquidation amount per share ($1,000 per share) and the per-share amount of any unpaid dividends for the then-current period, subject to any required prior approval by the Company’s primary federal banking regulator. The terms of the SBLF Preferred Stock imposed limits on the ability of the Company to pay dividends and repurchase shares of common stock. Under the terms of the SBLF Preferred Stock, no repurchases could be effected, and no dividends could be declared or paid on preferred shares ranking pari passu with the SBLF Preferred Stock, junior preferred shares, or other junior securities (including the common stock) during the current quarter and for the next three quarters following the failure to declare and pay dividends on the SBLF Preferred Stock, except that, in any such quarter in which the dividend was paid, dividend payments on shares ranking pari passu could be paid to the extent necessary to avoid any resulting material covenant breach.  The Company redeemed the SBLF Preferred Stock on February 23, 2016.

OFF-BALANCE SHEET ACTIVITIES

NOTE 14—OFF-BALANCE SHEET ACTIVITIES

Credit-Related Financial Instruments

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

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

Financial instruments with contract amounts representing credit risk as of December 31, 2017 and 2016 were as follows:

	December 31,
	2017		2016
	(dollars in thousands)
Commitments to extend credit and unused lines of credit, including unused    credit card lines	$	235,807	$	181,124
Standby letters of credit		5,357		5,599

Commitments to extend credit are agreements to lend funds 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. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if deemed necessary by the Bank, 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 to existing customers. These lines of credit are usually collateralized and contain a specified maturity date and may not be drawn upon to the total extent to which the Bank is committed.

Standby letters of credit are conditional commitments issued by the Bank to guarantee the payment or the performance of a Bank customer to a third party. Both standby and performance letters of credit are generally issued for terms of one to four years. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank generally holds collateral supporting these commitments.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

NOTE 15—DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Derivative Loan Commitments

Loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. The Company enters into commitments to fund loans at specified times in the future, with the intention that these loans will subsequently be sold in the secondary market. A loan commitment binds the Company to lend funds to a potential borrower at a specified interest rate and within a specified period of time, generally up to 60 days after inception of the rate lock.

Outstanding derivative loan commitments expose the Company to the risk that the price of the loans arising from exercise of the loan commitment might decline from inception of the rate lock to funding of the loan due to increases in interest rates. If interest rates increase, the value of these loan commitments decreases. Conversely, if interest rates decrease, the value of these loan commitments increases. The notional amount of interest rate lock commitments was $0 at both December 31, 2017, 2016, and 2015.

Collateral Requirements

To reduce credit risk related to the use of derivatives financial instruments, the Company might deem it necessary to obtain collateral. The amount and nature of the collateral obtained is based on the Company’s credit evaluation of the customer. Collateral held varies, but may include cash, securities, accounts receivable, inventory, property, plant and equipment and real estate. If the counterparty does not have the right and ability to redeem the collateral or the Company is permitted to sell or re-pledge the collateral on short notice, the Company records the collateral in its balance sheet at fair value with a corresponding obligation to return it.

EQUITY INCENTIVE PLAN

NOTE 17—EQUITY INCENTIVE PLAN

In 2016, the shareholders’ approved the Company’s 2016 Equity Incentive Compensation Plan (the “Plan”), which replaced the Company’s 2012 Equity Incentive Compensation Plan.  Under the Plan, the Company may grant options and stock awards to its directors, officers and employees for shares of common stock. Both qualified and non-qualified stock options, stock appreciation rights, restricted stock, and restricted stock units may be granted and issued, respectively, under the Plan.

The exercise price of options is no less than the market price of the Company’s stock on the date of grant and an option’s maximum term is ten years. Vesting periods for options and restricted stock range from one to five years from the date of grant.  

On February 27, 2017, the Company granted 5,988 restricted stock awards to certain members of management and lenders with a grant date value of $27.31 per share which was the Nasdaq Official Closing Price on that day.  The shares were awarded at no cost to the employee and have a ratable annual vesting period of five years from date of issue.  Compensation cost to be recognized over the five-year period, net of income tax, is $131 thousand.  As of December 31, 2017, none of the awards were vested, and 948 shares had been forfeited.  Unrecognized compensation expense, at December 31, 2017, net of income tax, was $216 thousand.

On February 27 2017 and June 20, 2017, the Company granted 4,461 and 4,230 restricted stock unit awards, respectively to certain members of management, lenders, and directors with grant date values of $27.31 and $23.66, respectively per share which was the Nasdaq official closing price on that day.  The shares were awarded at no cost to the employee.  The shares issued on February 27, 2017, have a ratable annual vesting period of five years from date of issue, and the shares issued on June 20, 2017 have a vesting period of one year from date of issue.  Compensation cost to be recognized over the vesting period is $178 thousand, net of income tax.  As of December 31, 2017, none of the awards were vested or forfeited.  Unrecognized compensation expense, at December 31, 2017, net of income tax, was $93 thousand.

The fair value of each option grant was estimated on the grant date using the Black-Scholes option-pricing model with the following assumptions:

	December 31,
	2017			2016
Risk-free interest rates	2.08-2.27%			1.49-1.64%
Dividend yields	0.74%-0.99%			0.96%-1.02%
Expected volatility		35.00	%		24.00	%
Weighted-average expected life of options	7.00 years			7.00 years

The expected volatility is based on historical volatility. The risk free rates for periods within the contractual life of the awards are based on the U.S. Treasury yield curve in effect at the time of the grant. The expected life is based on historical exercise experience. The dividend yield assumption is based on the Company’s history of declaring dividends on its common stock.

The activity of the Company’s outstanding stock options for the years ended December 31, 2017 and 2016 were as follows:

	December 31, 2017							December 31, 2016

(1) The aggregate intrinsic value of a stock option in the table above represents the total pre-tax intrinsic value (the amount by which the current market value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders had all option holders exercised their options on December 31, 2017 and 2016. This amount changes based on changes in the market value of the Company’s stock.

(2) The fair value (present value of the estimated future benefit to the option holder) of each option grant is estimated on the date of grant using the Black-Scholes option pricing model.

Regulatory Capital Requirements [Abstract]

REGULATORY MATTERS

NOTE 18—REGULATORY MATTERS

The Company (on a consolidated basis) and Bank are each subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and 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 the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios (set forth in the following table) of Total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined in the regulations), of Tier 1 capital (as defined in the regulations) to average assets (as defined in the regulations), and of Tier 1 Common Equity (as defined) to risk-weighted assets. Management believed, as of December 31, 2017 and 2016, that the Company and Bank met all capital adequacy requirements to which they were subject.

As of December 31, 2017, the most recent notification from the banking regulators categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain minimum Total risk-based, Tier 1 risk-based, Tier 1 leverage and Tier 1 Common Equity ratios as set forth in the following tables. There were no conditions or events since the notification that management believes have changed the Bank’s category.

The Company’s and Bank’s actual capital amounts and ratios are presented in the following table:

The Basel III Rule, which became effective January 1, 2015, revised the prompt corrective action requirements by, among other things: (i) introducing a Common Equity Tier 1 ratio requirement at each level (other than critically undercapitalized), with the required Common Equity Tier 1 ratio being 6.5% for “well-capitalized” status; (ii) increasing the minimum Tier 1 capital ratio requirement for each category (other than critically undercapitalized), with the minimum Tier 1 capital ratio for “well-capitalized” status being 8% (compared to the prior ratio of 6%); and (iii) eliminating the former provision that provided that a bank with a composite supervisory rating of 1 may have a 3% Leverage Ratio and still be adequately capitalized. The Basel III Rule did not change the total risk based capital requirement for any prompt corrective action category.  The Basel III Rule also implemented a capital conservation buffer that is added to the minimum requirements for capital adequacy purposes.  The capital conservation buffer is subject to a three year phase-in period that began on January 1, 2016 and will be fully phased in on January 1, 2019 at 2.5%.  The required phase-in capital conservation buffer during 2017 and 2016 was 1.25% and 0.625%, respectively.  As of December 31, 2017 and 2016, the ratios for the Company and the Bank were sufficient to meet the fully phased-in conservation buffer.

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

NOTE 20—FAIR VALUE MEASUREMENTS

Determination of Fair Value

The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimate of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.

Guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is considered a reasonable point within the range that is most representative of fair value under current market conditions.

Fair Value Hierarchy

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

Level 1—Valuation is based on quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.

Level 2—Valuation is based on inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. The valuation may be based on quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3—Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which determination of fair value requires significant management judgment or estimation.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

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

Cash and Cash Equivalents and Interest-Bearing Deposits in Banks

The carrying amounts of cash and short-term instruments approximate fair values based on the short-term nature of the assets.

Fair values of other interest-bearing deposits are estimated using discounted cash flow analyses based on current rates for similar types of deposits.

Securities Available for Sale

Where quoted prices are available in an active market, the Company classifies the securities within Level 1 of the valuation hierarchy. Securities are defined as both long and short positions. Level 1 securities include highly liquid government bonds and exchange-traded equities.

If quoted market prices are not available, the Company estimates fair values using pricing models and discounted cash flows that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes and credit spreads.

Examples of such instruments, which would generally be classified within Level 2 of the valuation hierarchy, include U.S. government and agency securities, corporate bonds and other securities. Mortgage-backed securities that are included in Level 2 if observable inputs are available. In certain cases where there is limited activity or less transparency around inputs to the valuation, the Company classifies those securities in Level 3.

Loans

For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values for certain mortgage loans (e.g., one-to-four family residential), credit card loans, and other consumer loans are based on quoted market prices of similar loans sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. Fair values for other loans (e.g., commercial and agricultural loans) are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values for non-performing loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable.

Loans Held for Sale

The carrying value of loans held for sale generally approximates fair value based on the short-term nature of the assets. If management identifies a loan held for sale that will ultimately sell at a value less than its carrying value, it is recorded at the estimated value.

Loan Servicing Rights

Fair value is based on market prices for comparable loan servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income.

Other Real Estate Owned

Loans on which the underlying collateral has been repossessed are adjusted to fair value upon transfer to other real estate owned. Subsequently, other real estate owned is carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral, or management’s estimation of the value of the collateral. Due to the significance of the unobservable inputs, all other real estate owned are classified as Level 3.

Deposits

The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts of variable-rate, fixed-term money market accounts and certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Other Borrowings

The carrying amounts of federal funds purchased, other borrowings and other short-term borrowings maturing within ninety days approximate their fair values. Fair values of other short-term borrowings are estimated using discounted cash flow analyses based on current market rates for similar types of borrowing arrangements.

Advances from FHLB

Current market rates for debt with similar terms and remaining maturities are used to estimate fair value of existing debt. Fair values are estimated using discounted cash flow analyses based on current market rates for similar types of borrowing arrangements.

Subordinated Debentures

The carrying amounts approximate fair value.

Accrued Interest

The carrying amounts approximate fair value.

Commitments to Extend Credit and Standby Letters of Credit

As of December 31, 2017 and 2016, the carrying and fair values of the commitment to extend credit and standby letters of credit are not considered significant.

Assets Measured at Fair Value on a Nonrecurring Basis

Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, they are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following table presents the financial instruments carried on the consolidated balance sheet by caption and by level in the fair value hierarchy for which a nonrecurring change in fair value has been recorded:

	Level 1 Inputs		Level 2 Inputs		Level 3 Inputs		Impairment Losses
	(dollars in thousands)
December 31, 2017
Impaired loans	$	—	$	—	$	33,002	$	1,436
Other real estate owned		—		—		4,962		905
Total assets at fair value	$	—	$	—	$	37,964	$	2,341

Other real estate owned		—		—		3,161		480
Total assets at fair value	$	—	$	—	$	23,265	$	1,816

The significant inputs used in the fair value measurements for Level 3 assets measured at fair value on a nonrecurring basis are as follows:

December 31, 2017
	Valuation Techniques	Unobservable Inputs	Range (Average)
Impaired loans	Evaluation of collateral	Estimation of value	NM*
Other real estate owned	Appraisal	Appraisal adjustment	0%-39% (14%)
December 31, 2016
	Valuation Techniques	Unobservable Inputs	Range (Average)
Impaired loans	Evaluation of collateral	Estimation of value	NM*
Other real estate owned	Appraisal	Appraisal adjustment	7%-39% (21%)

* Not Meaningful. Evaluations of the underlying assets are completed for each impaired loan with a specific reserve. The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate. Collateral evaluations are reviewed and discounted as appropriate based on knowledge of the specific type of collateral. In the case of real estate, an independent appraisal may be obtained. Types of discounts considered include aging of receivables, condition of the collateral, potential market for the collateral, and estimated disposal costs. These discounts will vary from loan to loan, thus providing a range would not be meaningful.

Impaired Loans

In accordance with the provisions of the loan impairment guidance, impairment was measured for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, or discounted cash flows. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceeds the recorded investments in such loans. Impaired loans for which an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. Collateral values are estimated using Level 3 inputs based on customized discounting criteria.

Impairment amounts on impaired loans represent specific valuation allowance and write-downs during the period presented on impaired loans that were individually evaluated for impairment based on the estimated fair value of the collateral less estimated selling costs, excluding impaired loans fully charged-off.

Other Real Estate Owned

Foreclosed assets are recorded at fair value based on property appraisals, less estimated selling costs, at the date of the transfer with any impairment amount charged to the allowance for loan losses. Subsequent to the transfer, foreclosed assets are carried at the lower of cost or fair value, less estimated selling costs with changes in fair value or any impairment amount recorded in the other non-interest expense. Values are estimated using Level 3 inputs based on customized discounting criteria. The carrying value of foreclosed assets is not re-measured to fair value on a recurring basis but is subject to fair value adjustments when the carrying value exceeds the fair value, less estimated selling costs.

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

	December 31, 2017				December 31, 2016
	Carrying Amount		Fair Value		Carrying Amount		Fair Value		Input Level

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2017

Accounting Policies [Abstract]

Nature of Business and Significant Concentrations of Credit Risk

Nature of Business and Significant Concentrations of Credit Risk

The Company is the sole shareholder of Investors Community Bank. The Bank is the sole member of Investors Insurance Services, LLC and ABS 1, LLC, which are both Wisconsin limited liability companies. The Company commenced operations in May of 1996; the Bank commenced operations in March of 1997. ICB Investment Corp. commenced operations in 2001. In July of 2010, the Bank formed Investors Insurance Services, LLC for the sole purpose of protecting the Bank from liability risk when selling crop insurance. Selling crop insurance had historically been a business function performed within the Bank. In September of 2011, the Bank formed ABS 1, LLC, for the sole purpose of holding real estate and personal property for sale which was obtained through repossession.  In November 2015, the Company formed County Acquisition LLC for the sole purpose of acquiring Fox River Valley Bancorp, Inc., and it was subsequently dissolved in May of 2016 after the Fox River Valley acquisition was completed.  In August of 2017, the Bank dissolved ICB Investment Corp., which was a wholly-owned Nevada subsidiary, and distributed its assets to the Bank.

The Bank provides a full range of banking and related financial services, which include real estate lending, business services, and agricultural finance, to individual and corporate customers primarily located within the state of Wisconsin. The Bank’s primary source of revenue is providing loans to customers, who are predominantly engaged in dairy farming and commercial activities. Its primary deposit products are savings and term certificate accounts. The Bank is subject to competition from other financial institutions and is regulated by federal and state banking agencies and undergoes periodic examinations by those agencies.

The Company has no other significant activities other than ownership of the Bank. Note 4 discusses the types of securities that the Company invests in. Note 5 discusses the types of lending that the Company engages in.

Agricultural loans, including agricultural operating, real estate and construction loans, represented 59.7% and 60.6% of our total loan portfolio at December 31, 2017 and 2016, respectively. Commercial real estate, including commercial construction loans, represented 25.5% and 26.3% of our total loan portfolio at December 31, 2017 and 2016, respectively.

Principles of Consolidation

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank, and the Bank’s wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company also has three wholly-owned subsidiaries, County Bancorp Statutory Trust II, County Bancorp Statutory Trust III, and Fox River Valley Capital Trust I, that are Delaware statutory trusts which have not been consolidated in accordance with accounting guidance related to variable interest entities.

Use of Estimates in Preparing Financial Statements

Use of Estimates in Preparing Financial Statements

The preparation of consolidated financial statements in conformity with generally accepted accounting procedures of the United States (“GAAP’) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of valuation of securities available for sale, the allowance for loan losses, loan servicing rights, other real estate owned, financial instruments, and deferred tax assets. Actual results could differ from those estimates.

Business Combinations and Valuation of Loans Acquired in Business Combinations

Business Combinations and Valuation of Loans Acquired in Business Combinations

We account for acquisitions under Financial Accounting Standards Board (“FASB”) ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. Assets acquired and liabilities assumed in a business combination are recorded at estimated fair value on their purchase date. As provided for under GAAP, management has up to 12 months following the date of the acquisition to finalize the fair values of acquired assets and assumed liabilities where it was not possible to estimate the acquisition date fair value upon consummation.

In particular, the valuation of acquired loans involves significant estimates, assumptions and judgments based on information available as of the acquisition date. Substantially all loans acquired in the transaction are evaluated either individually or in pools of loans with similar characteristics; since the estimated fair value of acquired loans includes a credit consideration, no carryover of any previously recorded allowance for loan losses is recorded at acquisition. A number of factors are considered in determining the estimated fair value of purchased loans including, among other things, the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, estimated holding periods, contractual interest rates compared to market interest rates, and net present value of cash flows expected to be received.

In determining the fair value of acquired loans, management calculates a nonaccretable difference (the credit mark component of the acquired loans) and an accretable difference (the market rate or yield component of the acquired loans). The nonaccretable difference is the difference between the undiscounted contractually required payments and the undiscounted cash flows expected to be collected in accordance with management’s determination of the fair value. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows will result in a reversal of the provision for loan losses to the extent of prior charges and then an adjustment to accretable yield and nonaccretable difference which would have a positive impact on interest income.

The accretable yield on acquired loans is the difference between the expected cash flows and the initial investment in the acquired loans. The accretable yield is recognized into earnings using the effective yield method over the term of the loans. Management separately monitors the acquired loan portfolio and periodically reviews loans contained within this portfolio against the factors and assumptions used in determining the fair value.

Cash and Cash Equivalents

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and balances due from banks and federal funds sold, all of which mature within 90 days.

In the normal course of business, the Company maintains balances with correspondent banks. Accounts at each institution are insured by the Federal Deposit Insurance Corporation up to specified limits. Management believes these financial institutions have strong credit ratings and the credit risk related to these deposits is minimal.

Securities Available for Sale

Securities Available for Sale

Available for sale securities are carried at fair value with unrealized gains and losses excluded from earnings and reported separately in other comprehensive income (loss). The Company currently has no securities designated as trading or held-to-maturity. 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. They are included in non-interest income or expense and, when applicable, are reported as a reclassification adjustment in other comprehensive income (loss).

Declines in the fair value of individual available for sale securities below their cost that are other than temporary result in write-downs of the individual securities to their fair value. The Company monitors the investment security portfolio for impairment on an individual security basis and has a process in place to identify securities that could potentially have a credit impairment that is other than temporary. This process involves analyzing the length of time and the extent to which the fair value has been less than the amortized cost basis, the market liquidity for the security, the financial condition and near-term prospects of the issuer, expected cash flows, and the Company’s intent and ability to hold the investment for a period of time sufficient to recover the temporary impairment. A decline in value due to a credit event that is considered other than temporary is recorded as a loss in non-interest income.

Federal Home Loan Bank Stock

Federal Home Loan Bank Stock

The Bank, as a member of the Federal Home Loan Bank of Chicago (“FHLB”), is required to maintain an investment in the capital stock of the FHLB based on the level of borrowings and other factors, and may invest additional amounts. Based on the redemption provisions of the FHLB, the stock has no quoted market value and is carried at cost. It is periodically evaluated by management for impairment. Because it is viewed as a long term investment, impairment is based on ultimate recovery of par value. Both stock and cash dividends are reported as income.

Loans Held for Sale

Loans Held for Sale

Loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value. Gains and losses on loan sales (sale proceeds minus carrying value) are recorded in non-interest income and direct loan origination costs and fees are deferred at origination of the loan and are recognized in non-interest income upon sale of the loan.

Loans

Loans

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balances adjusted for unearned income and the allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, non-refundable fees and direct loan origination costs on real estate and commercial loans are, in the opinion of management, insignificant and recognized as current income and are not accounted for as an adjustment of yield of the related loan categories.

The accrual of interest on mortgage and commercial loans is discontinued at the time the principal and interest is 90 days delinquent unless the credit is well-secured and in the process of collection.  Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful.

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

Allowance for Loan Losses

Allowance for Loan Losses

The allowance for loan losses (hereinafter referred to as “allowance”) is an estimate of loan losses inherent in the Company’s loan portfolio. The allowance is established through a provision for loan losses which is charged to expense. Additions to the allowance are expected to maintain the adequacy of the total allowance after loan losses and loan growth. Loan losses are charged off against the allowance when the Company determines the loan balance to be uncollectible. Cash received on previously charged off amounts is recorded as a recovery to the allowance.

The allowance consists of two primary components, general reserves and specific reserves related to impaired loans. The general component covers non-impaired loans and is based on historical losses adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on a weighted average of the actual loss history experienced by the Company over the most recent four years. The Company places more emphasis, or weight, on the more current quarters in the loss history period. This actual loss experience is adjusted for economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. These factors are inherently subjective and are driven by the repayment risk associated with each portfolio segment.

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is generally measured on a loan by loan basis by either the present value of expected future cash flows discounted at the loans’ effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

Under certain circumstances, the Company will provide borrowers relief through loan restructurings. A restructuring of debt constitutes a troubled debt restructuring (“TDR”) if the Company for economic or legal reasons related to the borrower’s financial difficulties grants a concession to the borrower that it would not otherwise consider. Restructured loans typically present an elevated level of credit risk as the borrowers are not able to perform according to the original contractual terms. Loans that are reported as TDRs are considered impaired and measured for impairment as described above. TDR concessions can include reduction of interest rates, extension of maturity dates, forgiveness of principal or interest due, or acceptance of other assets in full or partial satisfaction of the debt. Restructured loans can involve loans remaining on nonaccrual, moving to nonaccrual, or continuing on accrual status, depending on the individual facts and circumstances of the borrower. Nonaccrual restructured loans are included and treated with other nonaccrual loans.

Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment disclosures, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower.

The Company maintains a separate general valuation allowance for each portfolio segment. These portfolio segments include agricultural, commercial, commercial real estate, residential real estate, and installment and consumer other with risk characteristics described as follows:

Agricultural: Agricultural loans generally possess a lower inherent risk of loss than real estate portfolio segments because these loans are generally underwritten to existing cash flows of operating businesses. Debt coverage is provided by business cash flows and economic trends influenced by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans.

Commercial: Commercial loans generally possess a lower inherent risk of loss than real estate portfolio segments because these loans are generally underwritten to existing cash flows of operating businesses. Debt coverage is provided by business cash flows, and economic trends influenced by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans.

Commercial Real Estate: Commercial real estate loans, including land and construction, generally possess a higher inherent risk of loss than other real estate portfolio segments. Adverse economic developments or an overbuilt market impact commercial real estate projects and may result in troubled loans. Trends in vacancy rates of commercial properties impact the credit quality of these loans. High vacancy rates reduce operating revenues and the ability for the properties to produce sufficient cash flow to service debt obligations.

Residential Real Estate: The degree of risk in residential mortgage and home equity lending depends primarily on the loan amount in relation to collateral value, the interest rate and the borrower’s ability to repay in an orderly fashion. These loans generally possess a lower inherent risk of loss than other real estate portfolio segments. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers’ capacity to repay their obligations may be deteriorating.

Installment and Consumer Other: The installment and consumer other loan portfolio is usually comprised of a large number of small loans. Most loans are made directly for consumer purchases. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate the borrowers’ capacity to repay their obligations may be deteriorating.

Although management believes the allowance to be adequate, ultimate losses may vary from its estimates. At least quarterly, the board of directors reviews the adequacy of the allowance, including consideration of the relevant risks in the portfolio, current economic conditions and other factors. If the board of directors and management determine that changes are warranted based on those reviews, the allowance is adjusted. In addition, the Company’s primary regulator reviews the adequacy of the allowance. The regulatory agencies may require additions to the allowance based on their judgment about information available at the time of their examinations.

Bank Premises and Equipment

Bank Premises and Equipment

Land is carried at cost. Bank premises and equipment are carried at cost, less accumulated depreciation. Depreciation is computed on the straight line method. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any recognized gain or loss is reflected in income for the period. The cost of maintenance and repairs is charged to expense as incurred; significant renewals and improvements are capitalized and a deduction is made from the property accounts for retirements of capitalized renewals or improvements. Gains and losses on dispositions are included in current operations.

Off-Balance Sheet Credit Related Financial Instruments

Off-Balance Sheet Credit Related Financial Instruments

In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded. The Company maintains a separate allowance for off-balance sheet commitments. Management estimates anticipated losses using historical data and utilization assumptions. The allowance for off-balance sheet commitments is included in other liabilities.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of carrying amount and the fair value less costs to sell.

Loan Servicing Rights

Loan Servicing Rights

Servicing assets are recognized as separate assets when rights are acquired through the sale of financial assets. Servicing rights resulting from the sale or securitization of loans originated by the Company are initially measured at fair value at the date of transfer. The Company subsequently measures each class of servicing asset using the amortization method. Under the amortization method, servicing rights are amortized in proportion to and over the period of estimated net servicing income. The amortized assets are assessed for impairment or increased obligation based on fair value at each reporting date.

Fair value is based on market prices for comparable servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. These variables change from quarter-to-quarter as market conditions and projected interest rates change, and may have an adverse impact on the value of the servicing right and may result in a reduction to non-interest income.

Servicing assets measured using the amortization method are evaluated and measured for impairment. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the carrying amount of the servicing assets for that tranche. The valuation allowance is adjusted to reflect changes in the measurement of impairment after the initial measure of the impairment.

Changes in the valuation allowances are reported with loan servicing fees on the income statement. Fair value in excess of the carrying amount of servicing assets for that stratum is not recognized.

Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of loan servicing rights is netted against loan servicing fee income.

Other Real Estate Owned

Other Real Estate Owned

Land purchased by the Bank that is held for sale is recorded at the lower of cost or market value.

Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value at the date of foreclosure less estimated costs to sell, 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 non-interest expense.

Impairment losses on assets to be held and used are measured at the amount by which the carrying amount of a property exceeds its fair value. The evaluation of impairment is inherently subjective and requires estimates that are susceptible to significant revisions as more information becomes available. Due to potential changes in conditions, it is at least reasonably possible that changes in fair values will occur in the near term and that such changes could materially affect the amounts reported in the Company’s financial statements. Costs of significant asset improvements are capitalized, whereas costs relating to holding assets are expensed. Revenue and expenses from operations and changes in the valuation allowance are included in other non-interest expense.

Cash Surrender Value of Bank Owned Life Insurance

Cash Surrender Value of Bank Owned Life Insurance

The Company has purchased life insurance policies on certain key executives. Bank owned life insurance is recorded at its cash surrender value, or the amount that can be realized, if lower.

Goodwill and Core Deposit Intangible

Goodwill and Core Deposit Intangible

Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired and is included as an asset on the consolidated balance sheets. Goodwill is not amortized but is subject to impairment tests on at least an annual basis. Core deposit intangible represents the value of the acquired customer core deposit bases and is included in as an asset on the consolidated balance sheets. The core deposit intangible has an estimated finite life, is amortized on an accelerated basis over a 66-month period, and is subject to periodic impairment evaluation.

Management will periodically review the carrying value of its long-lived and intangible assets to determine if any impairment has occurred or whether changes in circumstances have occurred that would require a revision to the remaining useful life, in which case an impairment charge would be recorded as an expense in the period of impairment. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. Goodwill was $5.0 million at December 31, 2017 and 2016.  There was no impairment charge to goodwill or core deposit intangible related to the Fox River Valley acquisition at December 31, 2017.  The net book value of core deposit intangible was $0.9 million and $1.4 million at December 31, 2017 and December 31, 2016, respectively.  Goodwill and core deposit intangible are included on the consolidated balance sheets.

Income Taxes

Income Taxes

The Company accounts for income taxes in accordance with income tax accounting guidance, which sets out a consistent framework to determine the appropriate level of tax reserves to maintain for uncertain tax positions.

The 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 determined based on the tax effects of the temporary 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%; 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% 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 the some portion or all of the deferred tax asset will not be realized.  For the year ended December 31, 2017, the value of our net deferred tax asset was reduced by $0.9 million and recorded as additional income tax expense as a result of the Tax Act that was enacted on December 22, 2017.

The Company files income taxes returns in the U.S. federal jurisdiction and in the state of Wisconsin. The Company is no longer subject to U.S. federal or state income tax examinations by tax authorities for years before 2014.

The Company recognizes interest and penalties on income taxes, if any, as a component of other non-interest expense.

Comprehensive Income

Comprehensive Income

Recognized revenue, expenses, gains, and losses are included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on securities available for sale, are reported as a separate component of the equity section of the consolidated balance sheet, such items, along with net income, are components of comprehensive income.

Equity Incentive Plan

Equity Incentive Plan

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

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

Treasury Stock

Treasury Stock

Common stock shares repurchased are recorded as treasury stock at cost.

Earnings per Share

Earnings per Share

Basic earnings per share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional potential 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 outstanding stock options, and are determined using the treasury stock method.

Treasury shares are not deemed outstanding for earnings per share calculations.

Transfers of Financial Assets

Transfers of Financial Assets

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

The transfer of a participating interest in an entire financial asset must also meet the definition of a participating interest. A participating interest in a financial asset has all of the following characteristics: (1) from the date of transfer, it must represent a proportionate (pro rata) ownership interest in the financial asset, (2) from the date of transfer, all cash flows received, except any cash flows allocated as any compensation for servicing or other services performed, must be divided proportionately among participating interest holders in the amount equal to their share ownership, (3) the rights of each participating interest holder must have the same priority, and (4) no party has the right to pledge or exchange the entire financial asset unless all participating interest holders agree to do so.

Advertising Costs

Advertising Costs

Advertising costs are expensed as incurred.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 20. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect the estimates.

Segments

Segments

The Company’s operations consist of one segment, community banking.  The operating results of this segment are regularly reviewed by management to make decisions about resource allocations and to assess performance.  Selected information is not presented separately for the Company's reportable segment, as there is no material difference between that information and the corresponding information in the consolidated financial statements.

New Accounting Pronouncements

New Accounting Pronouncements

In November 2015, FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes. This ASU requires entities to present deferred tax assets (DTAs) and deferred tax liabilities (DTLs), along with any related valuation allowance, as noncurrent in a balance sheet. This ASU eliminates current guidance requiring deferred taxes for each jurisdiction to be presented as a net current asset or liability and a net noncurrent asset or liability. As a result, each jurisdiction would have one net noncurrent DTA or DTL balance. The ASU does not change the existing requirement that only permits offsetting DTAs and DTLs within a particular jurisdiction. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016, with early adoption permitted. This guidance was adopted during 2017 and did not have any material impact on the Company’s consolidated financial statements.

In January 2016, FASB issued ASU No. 2016-01, Financial Instruments: Recognition and Measurement of Financial Assets and Financial Liabilities, to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This amendment supersedes the guidance to classify equity securities with readily determinable fair values into different categories, requires equity securities to be measured at fair value with changes in the fair value recognized through net income, and simplifies the impairment assessment of equity investments without readily determinable fair values. The amendment requires public business entities that are required to disclose the fair value of financial instruments measured at amortized cost on the balance sheet to measure that fair value using the exit price notion. The amendment requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option. The amendment requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or in the accompanying notes to the financial statements. The amendment reduces diversity in current practice by clarifying that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity’s other deferred tax assets. This amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Entities should apply the amendment by means of a cumulative-effect adjustment as of the beginning of the fiscal year of adoption, with the exception of the amendment related to equity securities without readily determinable fair values, which should be applied prospectively to equity investments that exist as of the date of adoption. The Company does not have any equity securities in its portfolio; the adoption of this ASU will have no effect on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases: Amendments to the FASB Accounting Standards Codification which requires companies to recognize all leases as assets and liabilities on the consolidated balance sheet. This ASU retains a distinction between finance leases and operating leases, and the classification criteria for distinguishing between finance leases and operating leases are substantially similar to the classification criteria for distinguishing between capital leases and operating leases in the current accounting literature. The result of retaining a distinction between finance leases and operating leases is that under the lessee accounting model, the effect of leases in a consolidated statement of comprehensive income and a consolidated statement of cash flows is largely unchanged from previous GAAP. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Earlier application is permitted. The Company is currently evaluating it leases and determining the effect of this ASU will have on its financial statements and disclosures, if any.

In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation to simplify several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The amendments in this update became effective beginning January 1, 2017 and did not have a significant impact the Company’s financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses, to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date.  The amendment replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.  This amendment is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years with early adoption permitted for the fiscal year beginning after December 15, 2018, including interim periods within those fiscal years.  Entities should apply this amendment a modified-retrospective approach, through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective.  The Company has engaged a third-party software consultant to assist in developing our loss model methodology, and is currently gathering historical data.  At this time, the effect this ASU will have on its consolidated financial statements is unknown.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments, to reduce the existing diversity in practice in how certain cash receipts and payments are presented and classified on the statement of cash flows.  The amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with early adoption permitted including adoption in an interim period.  Entities should apply this amendment as of the beginning of the first reporting period in which the guidance is effective.  The adoption of this guidance is not expected to have a material impact on its consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash: A Consenus of the FASB Emerging Issues Task Force, to standardize the classification and presentation of changes to restricted cash on the statement of cash flows.  The amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with early adoption permitted including adoption in an interim period.  Entities should apply this amendment using a retrospective transition method to each period presented.  The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04 Intangibles – Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment.  This update eliminates Step 2 of the goodwill impairment test, and instead, recognizes an impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value not to exceed the total amount of goodwill allocated.  The Company early adopted this amendment effective January 1, 2017 for its goodwill impairment analysis.  The result of this amendment had no impact on the Company since its goodwill is not impaired as of December 31, 2017.

In March 2017, the FASB issued updated guidance codified within ASU No. 2017-08, Receivables – Nonrefundable Fees and Other Costs, which is intended to enhance the accounting for the amortization of premiums for purchased callable debt securities. The amendment is effective for fiscal years beginning after December 15, 2018, with early adoption permitted including adoption in an interim period. The Company is currently evaluating the effects this ASU will have on its consolidated financial statements.

In May 2017, the FASB issued updated guidance codified within ASU No. 2017-09, Compensation – Stock Compensation to provide clarity and reduce the diversity in practice and cost and complexity of applying the guidance when there is a change of terms condition of share-based awards. The amendment is effective for fiscal years beginning after December 15, 2017, with early adoption permitted including adoption in an interim period. The adoption of this ASU is not expected to have a significant impact on the Company’s consolidated financial because modification to share-based awards are rarely made.

In September 2017, the FASB issued updated guidance codified within ASU No. 2017-13, Revenue Recognition, Revenue from Contracts with Customers, Leases (Topic 840), and Leases (Topic 842) to clarify the amendment to the SEC paragraphs pursuant to the staff announcement on July 20, 2017 and update ASU No. 2016-20 Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers which was an update to ASU 2014-09 Revenue from Contracts with Customers, is the culmination of efforts by the FASB and the International Accounting Standards Board to develop a common revenue standard for GAAP and International Financial Reporting Standards. ASU 2014-09 supersedes Topic 605—Revenue Recognition and most industry-specific guidance. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those good or services. The guidance in ASU 2014-09 describes a 5-step process entities can apply to achieve the core principle or revenue recognition and requires disclosures sufficient to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers and the significant judgments used in determining that information. The amendments in ASU 2016-20 narrow the aspects of the guidance issued within ASU 2014-09 and are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period and early application is not allowed. The Company is currently cataloging revenue streams and reviewing current policies and practices to identify differences under this ASU.  The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which requires companies to reclassify the stranded effects in other comprehensive income to retained earnings as a result of the change in the tax rates under the Tax Cuts and Jobs Act (the 2017 Tax Act”).  The amendment is effective for fiscal years beginning after December 15, 2018, with early adoption permitted including adoption in an interim period.  The Company plans to early adopt this amendment during the first quarter of 2018 and will include the impact of the reclassification from other comprehensive income to retained earnings is included in the Statement of Changes in Shareholders’ Equity.
