MidWestOne Financial Group, Inc. and Subsidiaries
Notes to Consolidated Financial Statements
(Unaudited)

1.    Principles of Consolidation and Presentation
MidWestOne Financial Group, Inc. (the “Company,” which is also referred to herein as “we,” “our” or “us”) is an Iowa corporation incorporated in 1983, a bank holding company under the Bank Holding Company Act of 1956, as amended, and a financial holding company under the Gramm-Leach-Bliley Act of 1999. Our principal executive offices are located at 102 South Clinton Street, Iowa City, Iowa 52240.
On August 21, 2018, the Company entered into a merger agreement with ATBancorp, an Iowa corporation, pursuant to which ATBancorp will merge with and into the Company. In connection with the merger, American Trust & Savings Bank, an Iowa state chartered bank and wholly owned subsidiary of ATBancorp, and American Bank & Trust Wisconsin, a Wisconsin state chartered bank and wholly owned subsidiary of ATBancorp, will merge with and into MidWestOne Bank, which will continue as the surviving bank. The merger agreement also provides that each of the outstanding shares of ATBancorp common stock will be converted into the right of ATBancorp shareholders to receive 117.5500 shares of Company common stock and $992.51 in cash. The corporate headquarters of the combined company will be in Iowa City, Iowa. The merger is anticipated to be completed in the first quarter of 2019. For further information, please refer to the Current Report on Form 8-K filed by the Company with the SEC on August 22, 2018.
The Company owns all of the common stock of MidWestOne Bank, an Iowa state non-member bank chartered in 1934 with its main office in Iowa City, Iowa (the “Bank”), and all of the common stock of MidWestOne Insurance Services, Inc., Oskaloosa, Iowa. We operate primarily through MidWestOne Bank, our bank subsidiary, and MidWestOne Insurance Services, Inc., our wholly owned subsidiary that operates an insurance agency business through six offices located in central and east-central Iowa.
The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all the information and notes necessary for complete financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”).GAAP. The information in this Quarterly Report on Form 10-Q is written with the presumption that the users of the interim financial statements have read or have access to the most recent Annual Report on Form 10-K of the Company, filed with the Securities and Exchange Commission (SEC)SEC on March 1, 2018,8, 2019, which contains the latest audited financial statements and notes thereto, together with Management’s Discussion and Analysis of Financial Condition and Results of Operations as of December 31, 20172018 and for the year then ended. Management believes that the disclosures in this Form 10-Q are adequate to make the information presented not misleading. In the opinion of management, the accompanying consolidated financial statements contain all adjustments (consisting of only normal recurring accruals) necessary to present fairly the Company’s financial position as of September 30, 2018March 31, 2019 and December 31, 2017,2018, and the results of operations and cash flows for the three and nine months ended September 30, 2018March 31, 2019 and 20172018. All significant intercompany accounts and transactions have been eliminated in consolidation.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect: (1) the reported amounts of assets and liabilities, (2) the disclosure of contingent assets and liabilities at the date of the financial statements, and (3) the reported amounts of revenues and expenses during the reporting period. These estimates are based on information available to management at the time the estimates are made. Actual results could differ from those estimates. The results for the three and nine months ended September 30, 2018March 31, 2019 may not be indicative of results for the year ending December 31, 2018,2019, or for any other period.
All significant accounting policies followed in the preparation of the quarterly financial statements are disclosed in the Annual Report on Form 10-K for the year ended December 31, 20172018.
In the consolidated statements of cash flows, cash and cash equivalents include cash and due from banks, interest-bearing deposits in banks, and federal funds sold.
Certain reclassifications have been made to prior periods’ consolidated financial statements to present them on a basis comparable with the current period’s consolidated financial statements.

2.    Effect of New Financial Accounting Standards
Accounting Guidance Adopted in 2018
In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contract with Customers (Topic 606). Subsequent to the issuance of ASU 2014-09, the FASB

issued targeted updates to clarify specific implementation issues including ASU No. 2016-08, “Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” ASU No. 2016-10, “Identifying Performance Obligations and Licensing,” ASU No. 2016-12, “Narrow-Scope Improvements and Practical Expedients,” and ASU No. 2016-20 “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers.” For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. Since the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other sections of GAAP, the new guidance did not have a material impact on revenue most closely associated with financial instruments, including interest income and expense. The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the ASU, including trust and asset management fees, service charges on deposit accounts, sales of other real estate, and debit card interchange fees. Based on this assessment, the Company concluded that ASU 2014-09 did not materially change the method in which the Company currently recognizes revenue for these revenue streams. The Company also completed its evaluation of certain costs related to these revenue streams to determine whether such costs should be presented as expenses or contra-revenue (i.e., gross versus net). Based on its evaluation, the Company determined that ASU 2014-09 also did not materially change the method in which the Company currently recognizes costs for these revenue streams. The Company adopted this update on January 1, 2018, utilizing the modified retrospective transition method. Since there was no net income impact upon adoption of the new guidance, a cumulative effect adjustment to opening retained earnings was not deemed necessary. See Note 14 “Revenue Recognition” for more information.

In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance in this update makes changes to the current GAAP model primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged. The treatment of gains and losses for all equity securities, including those without a readily determinable market value, is expected to result in additional volatility in the income statement, with the loss of mark to market via equity for these investments. Additionally, changes in the allowable method for determining the fair value of financial instruments in the financial statement footnotes (“exit price” only) require changes to current methodologies of determining these values, and how they are disclosed in the financial statement footnotes. The new standard applies to public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted this update on January 1, 2018. With the elimination of the classification of available for sale equity securities, the net unrealized gain or loss on these securities that had been included in accumulated other comprehensive income at December 31, 2017, in the amount of $57,000, has been transferred to retained earnings, as shown in the consolidated statements of shareholders’ equity. Changes in the fair value of equity securities with readily determinable fair values are now reflected in the noninterest income portion of the consolidated statements of income, in the other gains (losses) line item. In accordance with the ASU requirements, the Company measured the fair value of its loan portfolio as of September 30, 2018 using an exit price notion. See Note 13. “Estimated Fair Value of Financial Instruments and Fair Value Measurements” to our consolidated financial statements.

Accounting Guidance Pending Adoption at September 30, 20182019
In February 2016, the FASB issued Accounting Standards UpdateASU No. 2016-02, Leases (Topic 842). The guidance in this update is meant to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. All leases create an asset and a liability for the lessee in accordance with FASB Concepts Statement No. 6, Elements of Financial Statements, and, therefore, recognition of those lease assets and lease liabilities represents an improvement over previous GAAP, which did not require lease assets and lease liabilities to be recognized for most leases. Disclosures are required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. To meet that objective, qualitative disclosures along with specific quantitative disclosures are required. The new standard appliesCompany adopted this update on January 1, 2019, utilizing the cumulative effect approach, and also elected certain relief options offered in ASU 2016-02 including the package of practical expedients, the option not to public businessseparate lease and non-lease components and instead to account for them as a single lease component, and the option not to recognize ROU assets and lease liabilities that arise from short-term leases (i.e., leases with terms of twelve months or less). The Company elected the hindsight

practical expedient, which allows entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted.to use hindsight when determining lease term and impairment of ROU assets. The Company has several lease agreements, such as branch locations, which are currently considered operating leases, and therefore notare now recognized on the Company’s consolidated balance sheets. The Company expects the new guidance will requirerequires these lease agreements to now be recognized on the consolidated balance sheets as right-of-use assetsa ROU asset and a corresponding lease liability. Therefore,See Note 18 “Leases” for more information. The Company also implemented internal controls and key system functionality to enable the Company’s preliminary evaluation indicates the provisionspreparation of ASU No. 2016-02 are expected to impact the Company’s consolidated statementsfinancial information on adoption. The adoption of income, along with the Company’s regulatory capital ratios. However, the Company continues

to evaluate the extent of potential impact the new guidance willthis standard did not have a material effect on the Company’s consolidated financial statements, and does not expect to early adopt the standard.statements.

Accounting Guidance Pending Adoption at March 31, 2019
In June 2016, the FASB issued Accounting Standards UpdateASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The amendment requires the use of a new model covering current expected credit losses (CECL),CECL, which will apply to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance sheet credit exposures. Upon initial recognition of the exposure, the CECL model requires an entity to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses (ECL)ECL should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments. The new guidance also amends the current available for sale (AFS)AFS security other-than-temporary impairment (OTTI)OTTI model for debt securities. The new model will require an estimate of ECL only when the fair value is below the amortized cost of the asset. The length of time the fair value of an AFS debt security has been below the amortized cost will no longer impact the determination of whether a credit loss exists. As such, it is no longer an other-than-temporary model. Finally, the purchased financial assets with credit deterioration (PCD)PCD model applies to purchased financial assets (measured at amortized cost or AFS) that have experienced more than insignificant credit deterioration since origination. This represents a change from the scope of what are considered purchased credit-impaired assets under today’sthe current model. Different than the accounting for originated or purchased assets that do not qualify as PCD, the initial estimate of expected credit losses for a PCD would be recognized through an allowance for loan and lease losses with an offset to the cost basis of the related financial asset at acquisition. The new standard applies to public business entities that are SEC filers in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 31, 2018, including interim periods within those fiscal years, and is expected to increase the allowance for loan lossesALLL upon adoption. The Company has formed a working group to evaluate the impact of the standard’s adoption on the Company’s consolidated financial statements, and has selected a software vendor to assist with implementation. The team meets periodically to discuss the latest developments, ensure progress is being made, and keep current on evolving interpretations and industry practices related to ASU 2016-13. The Company’s preliminary evaluation indicates the provisions of ASU No. 2016-13 are expected to impact the Company’s consolidated financial statements, in particular the level of the reserve for credit losses. The Company is continuing to evaluate the extent of the potential impact.

In August 2018, the FASB issued Accounting Standards UpdateASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, including the consideration of costs and benefits. Four disclosure requirements were removed, three were modified, and two were added. In addition, the amendments eliminate “at a minimum” from the phrase “an entity shall disclose at a minimum” to promote the appropriate exercise of discretion by entities when considering fair value measurement disclosures and to clarify that materiality is an appropriate consideration of entities and their auditors when evaluating disclosure requirements. The amendments in this update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until their effective date. The Company is considering the early adoption of removed and modified disclosures. The adoption of this standard is not expected to have a material effect on the Company’s consolidated financial statements.

InvestmentDebt securities with a carrying value of $217.8$191.3 million and $237.4$197.2 million at September 30, 2018March 31, 2019 and December 31, 20172018, respectively, were pledged on public deposits, securities sold under agreements to repurchase and for other purposes, as required or permitted by law.
As of September 30, 2018, the Company owned $0.4 million of equity securities in banks and financial service-related companies, and $2.4 million of mutual funds invested inCertain debt securities AFS and other debt instruments that will cause units of the fund to be deemed to be qualified under the Community Reinvestment Act. Prior to January 1, 2018, we accounted for our marketable equity securities at fair value with unrealized gains and losses recognized in accumulated other comprehensive income on the balance sheet. Realized gains and losses on marketable equity securities sold or impaired were recognized in noninterest income. Effective with the January 1, 2018 adoption of ASU 2016-01, both the realized

and unrealized net gains and losses on equity securities are required to be recognized in the statement of income. A breakdown between net realized and unrealized gains and losses is provided later in this financial statement footnote. These net changes are included in the other gains line item in the noninterest income section of the Consolidated Statements of Income.
The summary of investment securities shows that some of the securities in the available for sale and held to maturity investment portfolios had unrealized losses, orHTM were temporarily impaired as of September 30, 2018March 31, 2019 and December 31, 20172018. This temporary impairment represents the estimated amount of loss that would be realized if the securities were sold on the valuation date. 

The following tables present information pertaining to debt securities with gross unrealized losses as of September 30, 2018March 31, 2019 and December 31, 20172018, aggregated by investment category and length of time that individual securities have been in a continuous loss position:

The Company'sCompany’s assessment of OTTI is based on its reasonable judgment of the specific facts and circumstances impacting each individual debt security at the time such assessments are made. The Company reviews and considers factual information, including expected cash flows, the structure of the debt security, the creditworthiness of the issuer, the type of underlying assets and the current and anticipated market conditions.
At September 30, 2018 and DecemberMarch 31, 2017, the Company’s mortgage-backed securities and collateralized mortgage obligations portfolios consisted of securities predominantly backed by one- to four-family mortgage loans and underwritten to the standards of and guaranteed by the following government-sponsored agencies: the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association, and the Government National Mortgage Association. The receipt of principal, at par, and interest on mortgage-backed securities is guaranteed by the respective government-sponsored agency guarantor, such that the Company believes that its mortgage-backed securities and collateralized mortgage obligations do not expose the Company to credit-related losses.
At September 30, 2018,2019, approximately 53%56% of the municipal bonds held by the Company were Iowa-based, and approximately 24%22% were Minnesota-based. The Company does not intend to sell these municipal obligations, and it is more likely than

not that the Company will not be required to sell them until the recovery of their cost. Due to the issuers’ continued satisfaction of their obligations under the securities in accordance with their contractual terms and the expectation that they will continue to do so, management’s intent and ability to hold these securities for a period of time sufficient to allow for any anticipated recovery in fair value, as well as the evaluation of the fundamentals of the issuers’ financial conditions and other objective evidence, the Company believed that the municipal obligations identified in the tables above were temporarily impaired as of September 30, 2018March 31, 2019 and December 31, 2017.2018.
At September 30, 2018March 31, 2019 and December 31, 2017,2018, the Company’s MBS and CMOs portfolios consisted of securities predominantly backed by one- to four-family mortgage loans and underwritten to the standards of and guaranteed by the following government-sponsored agencies: the FHLMC, the FNMA, and the GNMA. The receipt of principal, at par, and interest on MBS is guaranteed by the respective government-sponsored agency guarantor, such that the Company believes that its MBS and CMOs do not expose the Company to credit-related losses.
At March 31, 2019 all but two, and on December 31, 2018, all but one, of the Company’s corporate bonds held an investment grade rating from Moody’s, S&P or Kroll, or carried a guarantee from an agency of the US government. We have evaluated  financial statements of the companycompanies issuing the non-investment grade bond and found the company’scompanies’ earnings and equity positionpositions to be satisfactory and in line with industry norms. Therefore, we expect to receive all contractual payments. The internal evaluation of the non-investment grade bondbonds along with the investment grade ratings on the remainder of the corporate portfolio lead us to conclude that all of the corporate bonds in our portfolio will continue to pay according to their contractual terms. Since the Company has the ability and intent to hold securities until price recovery, we believe that there is no other-than-temporary-impairment in the corporate bond portfolio.
It is reasonably possible that the fair values of the Company’s investmentdebt securities could decline in the future if interest rates increase or the overall economy or the financial conditions of the issuers deteriorate. As a result, there is a risk that OTTI may be recognized in the future, and any such amounts could be material to the Company’s consolidated statements of income.
Unless certain conditions are met, investment securities classified as held to maturity may not be sold without calling into question the Company’s intent to hold other debt securities so classified (“tainting”). One acceptable condition, outlined in Accounting Standards Codification 320-10-25-6(a), is the significant deterioration of an issuer’s creditworthiness. During the first quarter of 2017, $1.2 million of debt securities from a single issuer in the state and political subdivisions category were identified by the Company as having an elevated level of credit risk and were internally classified as “watch.” Given the significant deterioration of the issuer’s creditworthiness, the Company sold the debt securities in March 2017. The Company believes the sale was in accordance with applicable accounting guidance and did not taint the remainder of the held to maturity portfolio.

The contractual maturity distribution of investment debt securities at September 30, 2018March 31, 2019, is summarized as follows:

Loan Portfolio Segment Risk Characteristics
Agricultural - Agricultural loans, most of which are secured by crops, livestock, and machinery, are provided to finance capital improvements and farm operations as well as acquisitions of livestock and machinery. The ability of the borrower to repay may be affected by many factors outside of the borrower’s control including adverse weather conditions, loss of livestock due to disease or other factors, declines in market prices for agricultural products and the impact of government regulations. The ultimate repayment of agricultural loans is dependent upon the profitable operation or management of the agricultural entity. Collateral for these loans generally includes accounts receivable, inventory, equipment and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business.
Commercial and Industrial - Commercial and industrial loans are primarily made based on the reported cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The collateral support provided by the borrower for most of these loans and the probability of repayment are based on the liquidation of the pledged collateral and enforcement of a personal guarantee, if any exists. The primary repayment risks of commercial and industrial loans are that the cash flows of the borrower may be unpredictable, and the collateral securing these loans may fluctuate in value. The size of the loans the Company can offer to commercial customers is less than the size of the loans that competitors with larger lending limits can offer. This may limit the Company’s ability to establish relationships with the largest businesses in the areas in which the Company operates. As a result, the Company may assume greater lending risks than financial institutions that have a lesser concentration of such loans and tend to make loans to larger businesses. Collateral for these loans generally includes accounts receivable, inventory, equipment and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business. In addition, a decline in the U.S. economy could harm or continue to harm the businesses of the Company’s commercial and industrial customers and reduce the value of the collateral securing these loans.

Commercial Real Estate - The Company offers mortgage loans to commercial and agricultural customers for the acquisition of real estate used in their businesses, such as offices, warehouses and production facilities, and to real estate investors for the acquisition of apartment buildings, retail centers, office buildings and other commercial buildings. The market value of real estate securing commercial 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. Adverse developments affecting real estate values in one or more of the Company’s markets could increase the credit risk associated with its loan portfolio. Additionally, real estate lending typically involves higher loan principal amounts than other loans, 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 Company’s control or that of the borrower could negatively impact the future cash flow and market values of the affected properties.
Residential Real Estate - The Company generally retains short-term residential mortgage loans that are originated for its own portfolio but sells most long-term loans to other parties while retaining servicing rights on the majority of those loans. The market value of real estate securing residential real estate loans can fluctuate as a result of market conditions in the geographic area in which the real estate is located. Adverse developments affecting real estate values in one or more of the Company’s markets could increase the credit risk associated with its loan portfolio. Additionally, real estate lending typically involves higher loan principal amounts than other loans, and the repayment of the loans generally is dependent, in large part, on the borrower’s continuing financial stability, and is therefore more likely to be affected by adverse personal circumstances.
Consumer - Consumer loans typically have shorter terms, lower balances, higher yields and higher risks of default than real estate-related loans. Consumer loan collections are dependent on the borrower’s continuing financial stability, and are therefore more likely to be affected by adverse personal circumstances. Collateral for these loans generally includes automobiles, boats, recreational vehicles, mobile homes, and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to recover and may fluctuate in value based on condition. In addition, a decline in the United States economy could result in reduced employment, impacting the ability of customers to repay their obligations.
Purchased Loans Policy
All purchased loans (nonimpaired and impaired) are initially measured at fair value as of the acquisition date in accordance with applicable authoritative accounting guidance. Credit discounts are included in the determination of fair value. An allowance for loan lossesALLL is not recorded at the acquisition date for loans purchased.

Individual loans acquired through the completion of a transfer, including loans that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable, are referred to herein as “purchased credit impairedPCI loans. In determining the acquisition date fair value and estimated credit losses of purchased credit impairedPCI loans, and in subsequent accounting, the Company accounts for loans individually. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized as a yield adjustment or as a loss accrual or valuation allowance. Expected cash flows at the purchase date in excess of the fair value of loans, if any, are recorded as interest income over the expected life of the loans if the timing and amount of future cash flows are reasonably estimable. Subsequent to the purchase date, increases in cash flows over those expected at the purchase date are recognized as interest income prospectively. The present value of any decreases in expected cash flows after the purchase date is recognized by recording an allowance for loan lossesALLL and a provision for loan losses. If the Company does not have the information necessary to reasonably estimate cash flows to be expected, it may use the cost-recovery method or cash-basis method of income recognition.
Charge-off Policy
The Company requires a loan to be charged-off, in whole or in part, as soon as it becomes apparent that some loss will be incurred, or when its collectability is sufficiently questionable that it no longer is considered a bankable asset. The primary considerations when determining if and how much of a loan should be charged-off are as follows: (1) the potential for future cash flows; (2) the value of any collateral; and (3) the strength of any co-makers or guarantors.

When it is determined that a loan requires a partial or full charge-off, a request for approval of a charge-off is submitted to the Company'sCompany’s President, ExecutiveSenior Vice President and Chief Credit Officer, and the Senior Regional Loan officer. The Bank'sBank’s board of directors formally approves all loan charge-offs. Once a loan is charged-off, it cannot be restructured and returned to the Company'sCompany’s books.

Allowance for Loan and Lease Losses
The Company requires the maintenance of an adequate allowance for loan and lease losses (“ALLL”) in order to cover estimated probable losses without eroding the Company’s capital base. Calculations are done at each quarter end, or more frequently if warranted, to analyze the collectability of loans and to ensure the adequacy of the allowance. In line with FDIC directives, the ALLL calculation does not include consideration of loans held for sale or off-balance-sheet credit exposures (such as unfunded letters of credit). Determining the appropriate level for the ALLL relies on the informed judgment of management, and as such, is subject to inexactness. Given the inherently imprecise nature of calculating the necessary ALLL, the Company’s policy permits the actual ALLL to be between 20% above and 5% below the “indicated reserve.”
Loans Reviewed Individually for Impairment
The Company identifies loans to be reviewed and evaluated individually for impairment based on current information and events and the probability that the borrower will be unable to repay all amounts due according to the contractual terms of the loan agreement. Specific areas of consideration include: size of credit exposure, risk rating, delinquency, nonaccrual status, and loan classification.
The level of individual impairment is measured using one of the following methods: (1) the fair value of the collateral less costs to sell; (2) the present value of expected future cash flows, discounted at the loan'sloan’s effective interest rate; or (3) the loan'sloan’s observable market price. Loans that are deemed fully collateralized or have been charged down to a level corresponding with any of the three measurements require no assignment of reserves from the ALLL.
A loan modification is a change in an existing loan contract that has been agreed to by the borrower and the Bank, which may or may not be a troubled debt restructure, or “TDR.”“TDR”. All loans deemed TDR are considered impaired. A loan is considered a TDR when, for economic or legal reasons related to a borrower’s financial difficulties, a concession is granted to the borrower that would not otherwise be considered. Both financial distress on the part of the borrower and the Bank’s granting of a concession, which are detailed further below, must be present in order for the loan to be considered a TDR.
All of the following factors are indicators that the debtor is experiencing financial difficulties (one or more items may be present):
The debtor is currently in default on any of its debt.
The debtor has declared or is in the process of declaring bankruptcy.
There is significant doubt as to whether the debtor will continue to be a going concern.
Currently, the debtor has securities being held as collateral that have been delisted, are in the process of being delisted, or are under threat of being delisted from an exchange.

Based on estimates and projections that only encompass the current business capabilities, the debtor forecasts that its entity-specific cash flows will be insufficient to service the debt (both interest and principal) in accordance with the contractual terms of the existing agreement through maturity.
Absent the current modification, the debtor cannot obtain funds from sources other than the existing creditors at an effective interest rate equal to the current market interest rate for similar debt for a non-troubled debtor.
The following factors are potential indicators that a concession has been granted (one or multiple items may be present):
The borrower receives a reduction of the stated interest rate for the remaining original life of the debt.
The borrower receives an extension of the maturity date or dates at a stated interest rate lower that the current market interest rate for new debt with similar risk characteristics.
The borrower receives a reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement.
The borrower receives a deferral of required payments (principal and/or interest).
The borrower receives a reduction of the accrued interest.

Loans Reviewed Collectively for Impairment
All loans not evaluated individually for impairment will be separated into homogeneous pools to be collectively evaluated. Loans will be first grouped into the various loan types (i.e. commercial, agricultural, consumer, etc.) and further segmented within each subset by risk classification (i.e. pass, special mention/watch, and substandard). Homogeneous loans past due 60-89 days and 90 days or more are classified special mention/watch and substandard, respectively, for allocation purposes.
The Company’s historical loss experience for each group segmented by loan type is calculated for the prior 20 quarters as a starting point for estimating losses. In addition, other prevailing qualitative or environmental factors likely to cause probable losses to vary from historical data are incorporated in the form of adjustments to increase or decrease the loss rate applied to each group. These adjustments are documented and fully explain how the current information, events, circumstances, and conditions impact the historical loss measurement assumptions.

Although not a comprehensive list, the following are considered key factors and are evaluated with each calculation of the ALLL to determine if adjustments to historical loss rates are warranted:

Changes in national and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments.
Changes in the quality and experience of lending staff and management.
Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses.
Changes in the volume and severity of past due loans, classified loans and non-performing loans.
The existence and potential impact of any concentrations of credit.
Changes in the nature and terms of loans such as growth rates and utilization rates.
Changes in the value of underlying collateral for collateral-dependent loans, considering the Company’s disposition bias.
The effect of other external factors such as the legal and regulatory environment.
The Company may also consider other qualitative factors for additional allowance allocations, including changes in the Company’s loan review process. Changes in the criteria used in this evaluation or the availability of new information could cause the allowance to be increased or decreased in future periods. In addition, bank regulatory agencies, as part of their examination process, may require adjustments to the allowance for loan lossesALLL based on their judgments and estimates.
The items listed above are used to determine the pass percentage for loans evaluated under ASC 450, and as such, are appliedIn addition to the loans risk rated pass. Duequalitative factors identified above, the Bank applies a qualitative adjustment to the inherent risks associated with special mention/watcheach Watch and Substandard risk-rated loans (i.e. early stages of financial deterioration, technical exceptions, etc.), this subset is reserved at a level that will cover losses above a pass allocation for loans that had a loss in the last 20 quarters in which the loan was risk-rated special mention/watch at the time of the loss. Substandard loans carry greater risk than special mention/watch loans, and as such, this subset is reserved at a level that will cover losses above a pass allocation for loans that had a loss in the last 20 quarters in which the loan was risk-rated substandard at the time of the loss. Ongoing analysis is performed to support these factor multiples.portfolio segment.

Included within the special mention/watch, substandard, and doubtful categories at September 30, 2018March 31, 2019 and December 31, 20172018 are purchased credit impairedPCI loans totaling $11.1$8.4 million and $12.6$8.9 million, respectively.
Below are descriptions of the risk classifications of our loan portfolio.
Special Mention/Watch - A special mention/watch asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Special mention/watch assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.
Substandard - Substandard loans are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
Doubtful - Loans 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 known facts, conditions and values, highly questionable and improbable.
Loss - Loans classified as loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be effected in the future.

The following table presents loans individually evaluated for impairment excluding purchased credit impaired loans, by class of loan,receivable, as of September 30, 2018March 31, 2019 and December 31, 2017:2018:

Non-accrual and Delinquent Loans
Loans are placed on non-accrual when (1) payment in full of principal and interest is no longer expected or (2) principal or interest has been in default for 90 days or more (unless the loan is both well secured with marketable collateral and in the process of collection). All loans rated doubtful or worse, and certain loans rated substandard, are placed on non-accrual.
A non-accrual assetloan may be restored to an accrual status when (1) all past due principal and interest has been paid (excluding renewals and modifications that involve the capitalizing of interest) or (2) the loan becomes well secured with marketable collateral and is in the process of collection. An established track record of performance is also considered when determining accrual status.
Delinquency status of a loan is determined by the number of days that have elapsed past the loan’s payment due date, using the following classification groupings: 30-59 days, 60-89 days and 90 days or more. Once a TDR has gone 90 days or more past due or is placed on nonaccrual status, it is included in the 90 days or more past due or nonaccrual totals.

The following table sets forth the composition of the Company’s recorded investment in loans on nonaccrual status and past due 90 days or more and still accruing by class of loans,receivable, excluding purchased credit impairedPCI loans, as of September 30, 2018March 31, 2019 and December 31, 2017:2018:

Not included in the loans above as of September 30, 2018March 31, 2019 and December 31, 20172018 were purchased credit impairedPCI loans with an outstanding balance of $0.3$0.5 million and $0.7$0.3 million, net of a discount of zero and $0.1 million,zero, respectively.
As of September 30, 2018,March 31, 2019, the Company had $0.1$0.2 million in commitments to lend additional funds to borrowers who have a nonperforming loan.
Purchased Loans
Purchased loans acquired in a business combination are recorded and initially measured at their estimated fair value as of the acquisition date. Credit discounts are included in the determination of fair value. An allowance for loan lossesALLL is not carried over. These purchased loans are segregated into two types: purchased credit impairedPCI loans and purchased non-credit impaired loans.

Purchased non-credit impaired loans are accounted for in accordance with ASC 310-20 “Nonrefundable Fees and Other Costs” as these loans do not have evidence of significant credit deterioration since origination and it is probable all contractually required payments will be received from the borrower.
Purchased credit impairedPCI loans are accounted for in accordance with ASC 310-30 “Loans and Debt Securities Acquired with Deteriorated Credit Quality” as they display significant credit deterioration since origination and it is probable, as of the acquisition date, that the Company will be unable to collect all contractually required payments from the borrower.
For purchased non-credit impaired loans the accretable discount is the discount applied to the expected cash flows of the portfolio to account for the differences between the interest rates at acquisition and rates currently expected on similar portfolios in the marketplace. As the accretable discount is accreted to interest income over the expected average life of the portfolio, the result will be interest income on loans at the estimated current market rate. We record a provision for the acquired portfolio as the loans acquired in the Central Bancshares, Inc. (“Central”) merger, which occurred in 2015, renew and the discount is accreted.
For purchased credit impairedPCI loans the difference between contractually required payments at acquisition and the cash flows expected to be collected is referred to as the non-accretable difference. Further, any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the expected remaining life of the loan if the timing and amount of the future cash flows are reasonably estimable. This discount includes
The Company updates its cash flow projections for PCI loans on an adjustment on loans that are not accruing or paying contractual interest so that interest income will be recognized at the estimated current market rate.

Subsequent to the purchase date,annual basis. Any increases in expected cash flows over those expected atafter the purchaseacquisition date and subsequent re-measurement periods are recognizedrecorded as interest income prospectively. The present value of anyAny decreases in expected cash flows after the purchaseacquisition date isand subsequent re-measurement periods are recognized by recording an allowance for credit losses and a provision for loan losses.

Changes in the accretable yield for loans acquired and accounted for under ASC 310-30 were as follows for the three and nine months ended September 30, 2018March 31, 2019 and 2017:2018:

5.    Derivatives and Hedging Activities
FASB ASC 815, Derivatives and Hedging (“ASC 815”), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments.
As required by ASC 815, theThe Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk,risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.
The Company does not use derivatives for trading or speculative purposes.
In accordance with the FASB’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s loans and borrowings.

The following table presents the total notional and gross fair value of the Company’s derivatives as of September 30, 2018March 31, 2019 and December 31, 2017.2018. The derivative asset and liability balances are presented on a gross basis, prior to the application of master netting agreements, as included in other assets and other liabilities, respectively, on the consolidated balance sheets.

Derivatives Designated as Hedging Instruments
The Company is exposed to changes in the fair value of certain of its fixed-rate assets due to changes in benchmark interest rates. The Company uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate, LIBOR. Interest rate swaps designated as fair value hedges involve the payment of fixed-rate amounts to a counterparty in exchange for the Company receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in interest income.
The table below presents the effect of the Company’s derivative financial instruments designated as hedging instruments on the consolidated statements of income for the three and nine months ended September 30, 2018March 31, 2019 and September 30, 2017:March 31, 2018:

Derivatives Not Designated as Hedging Instruments
Interest Rate Swaps -The Company enters into interest rate derivatives, including interest rate swaps with its customers, to allow them to hedge against the risk of rising interest rates by providing fixed rate loans. To economically hedge against the interest rate risks in the products offered to its customers, the Company enters into mirrored interest rate contracts with institutional counterparties, with one designated as a central counterparty. The following table represents the notional amounts and the gross fair values of interest rate derivative contracts outstanding as of September 30, 2018March 31, 2019 and December 31, 2017 respectively.2018.

Credit Risk Participation Agreements -The Company may periodically enter into RPAs to manage the credit exposure on interest rate contracts associated with a syndicated loan. The Company may enter into protection purchased RPAs with institutional counterparties to decrease or increase its exposure to a borrower. Under the RPA, the Company will receive or make payment if a borrower defaults on the related interest rate contract. The Company manages its credit risk on RPAs by monitoring the creditworthiness of the borrowers and institutional counterparties, which is based on the normal credit review process. The notional amount of the RPAs reflects the Company’s pro-rata share of the derivative instrument. The following table represents the notional amounts and the gross fair values of RPAs purchased and sold outstanding as of September 30, 2018March 31, 2019 and December 31, 2017 respectively.2018.

6.    Goodwill and Intangible Assets
The excess of the cost of an acquisition over the fair value of the net assets acquired, including core deposit, trade name, and client relationship intangibles, consists of goodwill. Under ASC Topic 350, goodwill and the non-amortizing portion of the trade name intangible are subject to at least annual assessments for impairment by applying a fair value based test. The Company reviews goodwill and the non-amortizing portion of the trade name intangible at the reporting unit level to determine potential impairment annually on October 1, or more frequently if events or changes in circumstances indicate that the carrying value may not be recoverable, by comparing the carrying value of the reporting unit with the fair value of the reporting unit. No impairment was recorded on either the goodwill or the trade name intangible assets during the ninethree months ended September 30, 2018.March 31, 2019. The carrying amount of goodwill was $64.7 million at September 30, 2018,March 31, 2019, the same as at December 31, 2017.

(2) Central Bancshares Capital Trust II and Barron Investment Capital Trust I were established by Central prior to the Company’s merger with Central, and the junior subordinated notes issued by Central were assumed by the Company.
The trust preferred securities are subject to mandatory redemption, in whole or in part, upon repayment of the junior subordinated notes at the stated maturity date or upon redemption of the junior subordinated notes. Each trust’s ability to pay amounts due on the trust preferred securities is solely dependent upon the Company making payment on the related

junior subordinated notes. The Company’s obligation under the junior subordinated notes and other relevant trust agreements, in aggregate, constitutes a full and unconditional guarantee by the Company of each trust’s obligations under the trust preferred securities issued by each trust. The Company has the right to defer payment of interest on the junior subordinated notes and, therefore, distributions on the trust preferred securities, for up to five years, but not beyond the stated maturity date in the table above. During any such deferral period the Company may not pay cash dividends on its stock and generally may not repurchase its stock.

In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118), which provides guidance regarding how a company is to reflect provisional amounts when necessary information is not yet available, prepared or analyzed sufficiently to complete its accounting for the effect of the changes in Public Law 115-97, commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). During the first quarter of 2018, the income tax expense recorded during the fourth quarter of 2017 was determined to be final.

12.13.    Earnings per Share
Basic per-share amounts are computed by dividing net income (the numerator) by the weighted-average number of common shares outstanding (the denominator). Diluted per-share amounts assume issuance of all common stock issuable

upon conversion or exercise of other securities, unless the effect is to reduce the loss or increase the income per common share from continuing operations.

The following table presents the computation of earnings per common share for the respective periods:

13.14.    Regulatory Capital Requirements and Restrictions on Subsidiary Cash
The Company (on a consolidated basis) and the Bank are subject to the Basel III Rules and the Dodd-Frank Act. The Basel III Rules are 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 $3 billion which are not publicly traded companies). As of December 31, 2018, the most recent notification from the FDIC categorized the Bank as “well capitalized” under the regulatory framework for prompt corrective action then in effect. There are no conditions or events since the notification that management believes have changed the Bank’s category. In order to be a “well-capitalized” depository institution, a bank must maintain a Common Equity Tier 1 capital ratio of 6.5% or more; a Tier 1 capital ratio of 8% or more; a Total capital ratio of 10% or more; and a leverage ratio of 5% or more. A capital conservation buffer, comprised of Common Equity Tier 1 capital, is also established above the regulatory minimum capital requirements. This capital conservation buffer was fully phased in at 2.5% on January 1, 2019. At March 31, 2019, the Company’s institution-specific capital conservation buffer necessary to avoid limitations on distributions and discretionary bonus payments was 4.26%, while the Bank’s was 3.95%.

(1) The ratios for December 31, 2018 include a capital conservation buffer of 1.875%, and the ratios for March 31, 2019 include a capital conservation buffer of 2.5%.
The ability of the Company to pay dividends to its shareholders is dependent upon dividends paid by the Bank to the Company. The Bank is subject to certain statutory and regulatory restrictions on the amount of dividends it may pay. In addition, subsequent to December 31, 2008, the Bank’s board of directors adopted a capital policy requiring it to maintain a ratio of Tier 1 capital to total assets of at least 8% and a ratio of total capital to risk-based capital of at least 10%. Failure to maintain these ratios also could limit the ability of the Bank to pay dividends to the Company.
The Bank is required to maintain reserve balances in cash on hand or on deposit with Federal Reserve Banks. Reserve balances totaled $1.9 million and $14.9 million as of March 31, 2019 and December 31, 2018, respectively.

15.    Commitments and Contingencies
Financial instruments with off-balance-sheet risk: The Bank is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, commitments to sell loans, and standby letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheets.
The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. A summary of the Bank’s commitments at March 31, 2019 and December 31, 2018, is as follows:
  March 31, 2019 December 31, 2018
 (in thousands)   
 Commitments to extend credit$530,671
 $521,270
 Commitments to sell loans309
 666
 Standby letters of credit16,002
 16,709
 Total$546,982
 $538,645

The Bank’s exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. 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 Bank evaluates each customer’s creditworthiness on a case-by-case

basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, crops, livestock, inventory, property and equipment, residential real estate and income-producing commercial properties.
Commitments to sell loans are agreements to sell loans held for sale to third parties at an agreed upon price.
Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements and, generally, have terms of one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank holds collateral, which may include accounts receivable, inventory, property, equipment and income-producing properties, that support those commitments, if deemed necessary. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Bank would be required to fund the commitment. The maximum potential amount of future payments the Bank could be required to make is represented by the contractual amount shown in the summary above. If the commitment is funded, the Bank would be entitled to seek recovery from the customer.
Contingencies: In the normal course of business, the Bank is involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the accompanying consolidated financial statements.
Concentrations of credit risk: Substantially all of the Bank’s loans, commitments to extend credit and standby letters of credit have been granted to customers in the Bank’s market areas. Although the loan portfolio of the Bank is diversified, approximately 72% of the loans are real estate loans and approximately 8% are agriculturally related. The concentrations of credit by type of loan are set forth in Note 4 “Loans Receivable and the Allowance for Loan Losses”. Commitments to extend credit are primarily related to commercial loans and home equity loans. Standby letters of credit were granted primarily to commercial borrowers. Investments in securities issued by state and political subdivisions involve certain governmental entities within Iowa and Minnesota. The carrying value of investment securities of Iowa and Minnesota political subdivisions totaled $132.4 million and $51.2 million, respectively, as of March 31, 2019. The amount of investment securities issued by one individual municipality did not exceed $5.0 million.

16.    Estimated Fair Value of Financial Instruments and Fair Value Measurements
Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Market participants are defined as buyers and sellers in the principal (or most advantageous) market for the asset or liability that have all of the following characteristics: 1) an unrelated party; 2) knowledgeable (having a reasonable understanding about the asset or liability and the transaction based on all available information; including information that might be obtained through due diligence efforts that are usual or customary); 3) able to transact; and 4) willing to transact (motivated but not forced or otherwise compelled to do so).
The FASB states “valuation techniques that are appropriate in the circumstances and for which sufficient data are available shall be used to measure fair value.” The valuation techniques for measuring fair value are consistent with the three traditional approaches to value: the market approach, the income approach, and the cost or asset approach.
In applying valuation techniques, the use of relevant inputs (both observable and unobservable) based on the facts and circumstances must be used. The FASB has defined a fair value hierarchy for these inputs which prioritizes the inputs into three broad levels:
Level 1 Inputs – Quoted prices (unadjusted) for identical assets or liabilities in active markets. A quoted price in an active market provides the most reliable evidence of fair value and is used to measure fair value whenever available. A contractually binding sales price also provides reliable evidence of fair value.
Level 2 Inputs – Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; inputs to the valuation methodology include quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs to the valuation methodology that utilize model-based techniques for which all significant assumptions are observable in the market.
Level 3 Inputs – Inputs to the valuation methodology are unobservable and significant to the fair value measurement; inputs to the valuation methodology that utilize model-based techniques for which significant assumptions are not observable in the market; or inputs to the valuation methodology that require significant management judgment or estimation, some of which may be internally developed.

Unobservable inputs should be used only to the extent that relevant observable inputs are not available; this allows for situations where there is little, if any, market activity for the asset or liability at the measurement date. Unobservable inputs should reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk.
It is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. The Company is required to use observable inputs, to the extent available, in the fair value estimation process unless that data results from forced liquidations or distressed sales. The Company used the following methods and significant assumptions to estimate fair value:

Investment Securities - The fair value for investment securities are determined by quoted market prices, if available (Level 1). The Company utilizes an independent pricing service to obtain the fair value of debt securities. On a quarterly basis, the Company selects a sample of 30 securities from its primary pricing service and compares them to a secondary independent pricing service to validate value. In addition, the Company periodically reviews the pricing methodology utilized by the primary independent service for reasonableness. Debt securities issued by the U.S. Treasury and other U.S. Government agencies and corporations, mortgage-backed securities,MBS, and collateralized mortgage obligationsCMOs are priced utilizing industry-standard models that consider various assumptions, including time value, yield curves, volatility factors, prepayment speeds, default rates, loss severity, current market and contractual prices for the underlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace (Level 2). Municipal securities are valued using a type of matrix, or grid, pricing in which securities are benchmarked against the treasury rate based on credit rating (Level 2). On an annual basis, a group of selected municipal securities have their credit rating evaluated by a securities dealer and that information is used to verify the primary independent service’s rating and pricing.
Loans Held for Sale - Loans held for sale are carried at the lower of cost or fair value, with fair value being based on binding contracts from third party investors (Level 2). The portfolio has historically consisted primarily of residential real estate loans.
Loans NetHeld for Investment - The estimated fair value of loans, net, was performed using the income approach, with the market approach used for certain nonperforming loans, resulting in a Level 3 fair value classification. The application of the income approach establishes value by methods that discount or capitalize earnings and/or cash flow, by a discount or capitalization rate that reflects market rate of return expectations, market conditions, and the relative risk of the investment. Generally, this can be accomplished by the discounted cash flow method. For loans that exhibited some characteristics of performance and where it appears that the borrower may have adequate cash flows to service the loan, a discounted cash flow analysis was used. The discounted cash flow analysis was based on the contractual maturity of the loan and market indications of rates, prepayment speeds, defaults and credit risk. For loans with balloon or interest only payment structures, the repayment was extended by assuming a renewal period beyond the current contractual maturity date. For loans analyzed using the asset approach, the fair value was determined based on the estimated values of the underlying collateral. For impaired loans, the estimated net sales proceeds was used to determine the fair value of the loans when deemed appropriate. The implied sales proceeds value provides a better indication of value than the income stream as these loans are not performing or exhibit strong signs indicative of nonperformance.
Collateral Dependent Impaired Loans, Net of Related Allowance - From time to time, a loan is considered impaired and an allowance for credit losses is established. The specific reserves for collateral dependent impaired loans are based on the fair value of the collateral less estimated costs to sell, based on appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available for similar loans and collateral underlying such loans, and resulted in a Level 3 classification for inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and management’s expertise and knowledge of the client and the client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted in accordance with the allowance policy.
Other Real Estate Owned (“OREO”)Foreclosed Assets, Net - OREOForeclosed assets, net represents property acquired through foreclosures and settlements of loans. Property acquired through or in lieu of foreclosure are initially recorded at fair value less estimated selling cost at the date of foreclosure, establishing a new cost basis. These assets are subsequently accounted for at the lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than every 18 months. These appraisals may utilize a single valuation approach or a combination of approaches, including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the

independent appraisers to adjust for differences between the comparable sales and income data available for similar loans and the collateral underlying such loans, resulting in a Level 3 classification for inputs for determining fair value. Real estate owned properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly.
Appraisals for both collateral dependent impaired loans and OREOforeclosed assets are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the Special Assets Department reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics.

Interest Rate Swaps - Interest rate swaps are valued by the Company'sCompany’s swap dealers using cash flow valuation techniques with observable market data inputs. The fair values estimated by the Company'sCompany’s swap dealers use interest rates that are observable or that can be corroborated by observable market data and, therefore, are classified within Level 2 of the valuation hierarchy. The Company has entered into collateral agreements with its swap dealers which entitle it to receive collateral to cover market values on derivatives which are in asset position, thus a credit risk adjustment on interest rate swaps is not warranted.
Credit Risk Participation Agreements — The Company enters into credit risk participation agreements (“RPAs”)RPAs with institutional counterparties, under which the Company assumes its pro-rata share of the credit exposure associated with a borrower’s performance related to interest rate derivative contracts. The fair value of RPAs is calculated by determining the total expected asset or liability exposure of the derivatives to the borrowers and applying the borrowers’ credit spread to that exposure. Total expected exposure incorporates both the current and potential future exposure of the derivatives, derived from using observable inputs, such as yield curves and volatilities. Accordingly, RPAs fall within Level 2.

Third party appraisals are obtained as to the value of the underlying asset, but disclosure of this information would not provide meaningful information, as the range will vary widely from loan to loan. Types of discounts considered include age of the appraisal, local market conditions, current condition of the property, and estimated sales costs. These discounts will also vary from loan to loan, thus providing a range would not be meaningful.

14.17.    Revenue Recognition
On January 1, 2018, the Company adopted ASU No. 2014-09 “Revenue from Contracts with Customers” (Topic 606) and all subsequent ASUs that modified Topic 606. As stated in Note 2. “Effect of New Financial Accounting Standards,” the implementation of the new standard did not have a material impact on the measurement or recognition of revenue; as such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting under Topic 605.
Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as trust and asset management fees, service charges on deposit accounts, sales of other real estate, and debit card interchange fees. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Substantially all of the Company’s revenue is generated from contracts with customers. Noninterest revenue streams in-scope of Topic 606 are discussed below.
Trust and Asset Management
Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time, and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered.

Service Charges on Deposit Accounts
Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts.
Fees, Exchange, and Other Service Charges
Fees, exchange, and other service charges are primarily comprised of debit and credit card income, ATM fees, merchant services income, and other service charges. Debit and credit card income is primarily comprised of interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as Visa. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees. Other service charges include revenue from processing wire transfers, bill pay service, cashier’s checks, and other services. The Company’s performance obligation for fees, exchange, and other service charges are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month.
Gains/Losses on Sales of OREOForeclosed Assets
Gain or loss from the sale of OREOforeclosed assets occurs when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of OREOforeclosed assets to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset isforeclosed assets are derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present. OREOForeclosed asset sales for the ninethree months ended September 30,March 31, 2019 and March 31, 2018 and September 30, 2017 were not financed by the Bank.
Other
Other noninterest income consists of other recurring revenue streams such as safe deposit box rental fees, and other miscellaneous revenue streams. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation.
Contract Balances
A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of September 30, 2018March 31, 2019 and December 31, 2017,2018, the Company did not have any significant contract balances.
Contract Acquisition Costs
In connection with the adoption of Topic 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Upon adoption of Topic 606, the Company did not capitalize any contract acquisition cost.

15.18.    Leases
A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On January 1, 2019, the Company adopted ASU No. 2016-02 “Leases” (Topic 842) and all subsequent ASUs that modified Topic 842. For the Company, Topic 842 primarily

affected the accounting treatment for operating lease agreements in which the Company is the lessee. As stated in Note 2. “Effect of New Financial Accounting Standards,” the implementation of the new standard did not have a material effect on the Company’s consolidated financial statements. The Company adopted the new standard utilizing the cumulative effect approach, and also elected certain relief options offered in ASU 2016-02 including the package of practical expedients, the option not to separate lease and non-lease components and instead to account for them as a single lease component, and the option not to recognize ROU assets and lease liabilities that arise from short-term leases (i.e., leases with terms of twelve months or less). The Company elected the hindsight practical expedient, which allows entities to use hindsight when determining lease term and impairment of ROU assets. The Company has several lease agreements for branch locations, which are considered operating leases, and are now recognized on the Company’s consolidated balance sheets.
Lessee Accounting
Substantially all of the leases in which the Company is the lessee are comprised of real estate property for branches and office space with terms extending through 2025. We do not have any subleased properties. Substantially all of our leases are classified as operating leases, and therefore, were previously not recognized on the Company’s consolidated balance sheets. With the adoption of Topic 842, operating lease agreements are required to be recognized on the consolidated statements of condition as a ROU asset and a corresponding lease liability. Upon adoption of ASU 2016-02, the Company recognized a ROU asset on its balance sheet in the amount of $2.9 million, and a corresponding operating lease liability of $2.9 million. The Company has one existing finance lease (previously referred to as a capital lease) for a branch location with a lease term through 2025. As this lease was previously required to be recorded on the Company’s consolidated statements of condition, Topic 842 did not materially impact the accounting for this lease.
The following table represents the consolidated statements of condition classification of the Company’s ROU assets and lease liabilities. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less) on the consolidated statements of condition.
 (in thousands)  March 31, 2019

 Operating lease right-of-use assets Other assets$2,719

 Lease Liabilities   
 Operating lease liability Other liabilities$2,723
 Finance lease liability Long-term debt1,310
 Total lease liabilities  $4,033

The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. For the Company’s only finance lease, the Company utilized the rate implicit in the lease.
The following table presents the weighted-average remaining term and weighted-average discount rate for both operating and finance leases as of March 31, 2019:
March 31, 2019
Weighted-average remaining lease term
Operating leases7.42 years
Finance lease4.97 years
Weighted-average discount rate

Finance lease8.89%

The following table represents lease costs and other lease information. As the Company elected, for all classes of underlying assets, not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance and utilities.

For further information, please refer to the Current Report on Form 8-K filed by the Company with the SEC on August 22, 2018.

17.20.    Subsequent Events
Management evaluated subsequent events through the date the consolidated financial statements were issued. Events or transactions occurring after September 30, 2018March 31, 2019, but prior to the date the consolidated financial statements were issued, that provided additional evidence about conditions that existed at September 30, 2018March 31, 2019 have been recognized in the consolidated financial statements for the three and nine months ended September 30, 2018March 31, 2019. Events or transactions that provided evidence about conditions that did not exist at September 30, 2018March 31, 2019, but arose before the consolidated financial statements were issued, have not been recognized in the consolidated financial statements for the three and nine months ended September 30, 2018March 31, 2019.
On October 16, 2018, the Board of Directors of the Company approved a new share repurchase program, allowing for the repurchase of up to $5.0 million of common stock through December 31, 2020. The new repurchase program replaces the Company's prior repurchase program, pursuant to which the Company had repurchased 33,998 shares of common stock for approximately $1.1 million since the plan was announced in July 2016. The prior program had authorized the repurchase of $5.0 million of stock and was due to expire on December 31, 2018.
On October 16, 2018April 18, 2019, the board of directors of the Company declared a cash dividend of $0.1950.2025 per share payable on December 15, 2018June 17, 2019 to shareholders of record as of the close of business on December 1, 2018April 29, 2019.
Pursuant to the Company’s share repurchase program approved on October 16, 2018, the Company purchased 9,523 shares of common stock subsequent to March 31, 2019 and through May 7, 2019 for a total cost of $0.3 million inclusive of transaction costs, leaving $2.3 million remaining available under the program.
On May 1, 2019, the Company entered into a $10.0 million unsecured line of credit with a correspondent bank. Interest is payable at a rate of one-month LIBOR plus 1.75%. The line expires on April 30, 2020.
On May 1, 2019, the Company completed its previously announced acquisition of ATBancorp, for total consideration of $152.9 million. The Company acquired all of the voting equity interests of ATBancorp. The primary reason for the acquisition was to expand into the Dubuque, Iowa market. The operating results of the Company for the three months ended March 31, 2019 do not include operating results produced by ATBancorp as the acquisition did not close until May 1, 2019. It is not practical to present other financial information related to the acquisition at this time because the fair value measurement of assets acquired and liabilities assumed has not been finalized.

We seek to maintain a disciplined pricing strategy on deposit generation that will allow us to compete for high quality loans while maintaining an appropriate spread over funding costs.
Our results of operations depend primarily on our net interest income, which is the difference between the interest income on our interest-earning assets, such as loans and securities, and the interest expense paid on our deposits and borrowings. Results of operations are also affected by non-interest income and expense, the provision for loan losses and income tax expense. Significant

external factors that impact our results of operations include general economic and competitive conditions, as well as changes in market interest rates, government policies, and actions of regulatory authorities.
The following discussion and analysis should be read in conjunction with the consolidated financial statements and related notes and the statistical information and financial data appearing in this report as well as our Annual Report on Form 10-K for the year ended December 31, 2017.2018. Results of operations for the three and nine months ended September 30, 2018March 31, 2019 are not necessarily indicative of results to be attained for any other period.

Critical Accounting Estimates
Critical accounting estimates are those which are both most important to the portrayal of our financial condition and results of operations, and require our management'smanagement’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Our critical accounting estimates relate to the allowance for loan losses,ALLL, application of purchase accounting, goodwill and intangible assets, and fair value of available for saleAFS investment securities, all of which involve significant judgment by our management. Information about our critical accounting estimates is included under Item 7, "Management'sManagement’s Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2017.2018.


RESULTS OF OPERATIONS
Comparison of Operating Results for the Three Months Ended September 30,March 31, 2019 and March 31, 2018 and September 30, 2017
Summary
For the quarter ended September 30, 2018,March 31, 2019, we earned net income of $6.8$7.3 million, which was an increasea decrease of $0.5 million from $6.3$7.8 million for the quarter ended September 30, 2017.March 31, 2018. The increasedecrease in net income was due primarily to a $3.4$0.4 million, or 78.3%1.9%, decreaseincrease in the allowance for loan lossesnoninterest expense between the two comparable periods, an increasedue primarily to increased compensation and employee benefits of $0.1$0.2 million, or 1.1%1.7%. Also contributing to the decrease in net income was a decrease of $0.3 million, or 4.8%, in noninterest income, and a $0.1 million, or 6.8%, decrease in income tax expense, stemming from the reduction in the maximum corporate federal income tax rate to 21% for 2018 compared to 35% for 2017. These increases were partially offset by an increase of $3.1 million, or 15.5%, in noninterest expense, due primarily to increased salaries and employee benefits of $1.0a $0.5 million decrease in loan revenue, related to a drop in residential loan originations attributable to the severe weather experienced in our market footprint during the quarter ended March 31, 2019. Net interest income was down $0.2 million, or 8.4%0.8%, and a $0.1 million, or 0.5%, decrease in net interest income, due primarily to an increase of $2.2$2.7 million in interest expense partially offset by an increase of $2.1$2.5 million in interest income. These decreases were partially offset by a $0.3 million, or 13.8%, decrease in the provision for loan losses, and a $0.1 million, or 4.7%, decrease in income tax expense. Both basic and diluted earnings per common share for the thirdfirst quarter of 20182019 were $0.55,$0.60, versus $0.52$0.64 for the thirdfirst quarter of 2017.2018. Our annualized return on average assets for the thirdfirst quarter of 20182019 was 0.83%0.89% compared with 0.81%0.98% for the same period in 2017.2018.

(1) A non-GAAP financial measure. See below for a reconciliation to the most comparable GAAP equivalents.
We have traditionally disclosed certain non-GAAP ratios, including our return on average tangible equity, and the ratio of our tangible equity to tangible assets, as well as adjusted noninterest income as a percentage of total revenue and tangible book value per share. We believe these financial measures provide investors with information regarding our financial condition and results of operations and how we evaluate them internally, such as presenting how management tracks adjusted noninterest income as a percentage of total revenue against its goal of 25%.internally.

Net Interest Income
Net interest income is the difference between interest income and fees earned on interest-earning assets and interest expense incurred on interest-bearing liabilities. Interest rate levels and volume fluctuations within interest-earning assets and interest-bearing liabilities impact net interest income. Net interest margin is net interest income as a percentage of average earning assets.
Certain assets with tax favorable treatment are evaluated on a tax-equivalent basis. Tax-equivalent basis assumes a federal income tax rate of 21% for 2018 and 35% for 2017.. Tax-favorable assets generally have lower contractual yields than fully taxable assets. A tax-equivalent analysis is performed by adding the tax savings to the earnings on tax-favorable assets. After factoring in the tax-favorable effects of these assets, the yields may be more appropriately evaluated against alternative earning assets. In addition to yield, various other risks are factored into the evaluation process.
Net interest income of $26.4$26.0 million for the thirdfirst quarter of 20182019 was down $0.1$0.2 million, or 0.5%0.8%, from $26.5$26.2 million for the thirdfirst quarter of 2017.2018. An increase in interest income of $2.1$2.5 million, or 6.9%8.2%, was more than offset by increased interest expense of $2.2$2.7 million, or 57.6%58.4%. Loan interest income increased $1.9$2.5 million, or 7.2%9.3%, to $28.1$29.0 million for the thirdfirst quarter of 2019 compared to the first quarter of 2018, compared to the third quarter of 2017, as a 221 basis point decreaseincrease in loan yield was more than offsetaugmented by a $155.7$104.7 million, or 7.0%4.5%, increase in average loan balances between the two periods. Merger-related loan discount accretion saw a decrease of $0.7$0.3 million to $0.6 million for the thirdfirst quarter of 2018.2019. Interest income from investment securities was $4.4$4.3 million for the thirdfirst quarter of 2018,2019, up $0.1 million from $4.1 million for the thirdfirst quarter of 2017.2018.
Interest expense increased $2.2$2.7 million, or 57.6%58.4%, to $6.1$7.4 million for the thirdfirst quarter of 2018,2019, compared to $3.9$4.7 million for the same period in 2017,2018, primarily due to an increase in the cost of interest-bearing deposits of 2838 basis points and an increase in the average balance of $133.9$74.2 million between the two periods. Interest expense on borrowed funds was $1.5$1.7 million for the thirdfirst quarter of 2019, up from $1.1 million for the first quarter of 2018, up from $1.0 million for the third quarter of 2017, an increase of $0.5$0.6 million, or 52.1%50.2%. This increase resulted from an increase of 5568 basis points in cost,rate, combined with a higheran increase in the average balance of borrowed funds of $277.7to $289.4 million for the thirdfirst quarter of 20182019 compared to $247.0$267.9 million for the same period last year, an increase of $30.7$21.5 million, or 12.4%8.0%, between the comparative periods.
Our net interest margin for the thirdfirst quarter of 2018,2019, calculated on a fully tax-equivalent basis, was 3.56%, or 2913 basis points lower than the net interest margin of 3.85%3.69% for the thirdfirst quarter of 2017.2018. The yield on loans decreased 2increased 21 basis points and the tax equivalent yield on investment securities decreasedincreased by 1013 basis points, primarily due to the reduction in the federal income taxincreasing interest rate environment, resulting in the yield on interest-earning assets for the thirdfirst quarter of 20182019 being 222 basis points lowerhigher compared to the thirdfirst quarter of 2017.2018. The cost of deposits increased 2838 basis points, while the average cost of borrowings was higher by 5568 basis points for the thirdfirst quarter of 2019, compared to the first quarter of 2018, compared to the third quarter of 2017,also reflecting the increasing interest rate environment. We expect further net interest margin compression pressure in the future as rates on deposits and borrowings are expected to increase more rapidly than yields on loans.

The following table shows consolidated average balance sheets, detailing the major categories of assets and liabilities, the interest income earned on interest-earning assets, the interest expense paid for interest-bearing liabilities, and the related yields and interest rates for the quarters ended September 30,March 31, 2019 and 2018, and 2017, reported on a fully tax-equivalent basis assuming a 21% tax rate for 2018 and a 35% tax rate for 2017.rate. Dividing annualized income or expense by the average balances of assets or liabilities results in average yields or costs. Average information is provided on a daily average basis.

 (1)Non-accrual loans have been included in average loans, net of unearned income. Amortized net deferred loans and net unearned discounts on acquired loans were included in the interest income calculations. The amortization of net deferred loans fees was $(128)$(150) thousand and $(99)$(132) thousand for the three months ended September 30,March 31, 2019 and March 31, 2018, and September 30, 2017, respectively. Accretion of unearned purchase discounts was $605$586 thousand and $1.3 million$878 thousand for the three months ended September 30,March 31, 2019 and March 31, 2018, and September 30, 2017, respectively.

(4)Net interest margin is tax-equivalent net interest income as a percentage of average interest-earning assets.

The following table sets forth an analysis of volume and rate changes in interest income and interest expense on our average interest-earning assets and average interest-bearing liabilities during the three months ended September 30, 2018,March 31, 2019, compared to the same period in 2017,2018, reported on a fully tax-equivalent basis assuming a 21% federal tax rate for 2018 and a 35% federal tax rate for 2017.rate. The table distinguishes between the changes related to average outstanding balances (changes in volume holding the initial interest rate constant) and the changes related to average interest rates (changes in average rate holding the initial outstanding balance constant). The change in interest due to both volume and rate has been allocated to volume and rate changes in proportion to the relationship of the absolute dollar amounts of the change in each.

Interest income and fees on loans on a tax-equivalent basis in the thirdfirst quarter of 20182019 increased $1.7$2.5 million, or 6.4%9.3%, compared with the same period in 2017.2018. This increase includes the effect of the merger-related discount accretion of $0.6 million on loans for the thirdfirst quarter of 20182019 compared to $1.3$0.9 million of merger-related discount accretion for the thirdfirst quarter of 2017.2018. Average loans were $155.7$104.7 million, or 7.0%4.5%, higher in the thirdfirst quarter of 20182019 compared with the thirdfirst quarter of 2017,2018, primarily resulting from new loan originations exceeding loan payments and payoffs. In addition to purchase accounting adjustments, the yield on our loan portfolio is affected by the amount of nonaccrual loans (which do not earn interest income), the mix of the portfolio (real estate loans generally have a lower overall yield than commercial and agricultural loans), the effects of competition and the interest rate environment on the amounts and volumes of new loan originations, and the mix of variable-rate versus fixed-rate loans in our portfolio. The increase in interest income on loans was primarilybalanced between an increase in the average yield on loans from 4.72% in the first quarter of 2018 to 4.93% in the first quarter of 2019, which was despite a decrease in purchase accounting adjustments, and the result of the increase in average balance of loans between the thirdfirst quarter of 20182019 and the comparative period in 2017. The effects of this increase were partially offset by a decrease in the average yield on loans from 4.76% in the third quarter of 2017 to 4.74% in the third quarter of 2018, which was primarily attributable to a decrease in purchase accounting adjustments and the reduction in the federal income tax rate.2018. Despite the increase in overall interest rates, we expect the yield on new and renewing loans to remain relatively flat for the remainder of 2019 in the markets we serve due to competitive pressures for quality credits.
Interest income on investment securities on a tax-equivalent basis totaled $4.7 million in the thirdfirst quarter of 20182019 compared with $5.0$4.7 million for the same period of 2017.2018. The tax-equivalent yield on our investment portfolio in the thirdfirst quarter of 2018 decreased2019 increased to 2.99%3.09% from 3.09%2.96% in the comparable period of 2017, primarily due to the impact of the reduction in the federal corporate income tax rate from 35% in 2017 to 21% in 2018. The average balance of investments in the thirdfirst quarter of 2019 was $617.0 million compared with $640.6 million in the first quarter of 2018, was $627.3 million compared with $635.4 million in the third quarter of 2017, a decrease of $8.2$23.6 million, or 1.3%3.7%.
Interest expense on deposits increased $1.7$2.2 million, or 59.5%61.1%, to $4.6$5.7 million in the thirdfirst quarter of 20182019 compared with$2.9with $3.5 million in the same period of 2017.2018. The increased interest expense on deposits was primarily due to an increase of 2838 basis points in the weighted average rate paid on interest-bearing deposits to 0.85%1.05% in the thirdfirst quarter of 2018,2019, compared with 0.57%0.67% in the thirdfirst quarter of 2017.2018. This increase was due to an increase in the targeted fed funds rate as well as competitive pressure in our market footprint. An increase in average balances of interest-bearing deposits for the thirdfirst quarter of 20182019 of $133.9$74.2 million

compared with the same period in 2017,2018, also contributed to increased expense on deposits. We expect to see some upward

movement in deposit rates in future periods, as overall interest rate increases continue in our market footprint due to competition for deposits.
Interest expense on borrowed funds of $1.5$1.7 million in the thirdfirst quarter of 20182019 was an increase of $0.5$0.6 million, or 52.1%50.2%, from $1.0$1.1 million in same period of 2017.2018. Average borrowed funds for the thirdfirst quarter of 2018 were $30.72019 saw a $21.5 million higherincrease compared with the same period in 2017. A higher2018. An increase in the level of borrowed funds, primarily due to the $31.8$18.3 million increase in the average level of FHLB borrowingslong-term debt combined with a $3.9$3.2 million increase in the average level of federal funds purchased and repurchase agreementsshort-term borrowings for the thirdfirst quarter of 2018,2019, compared to the same period in 2017,2018, was enhanced by an increase in the weighted average rate on borrowed funds to 2.11%2.41% for the thirdfirst quarter of 20182019 compared with 1.56%1.73% for the thirdfirst quarter of 2017.2018. The increase in the weighted average rate was due to the interest rate on a portion of the Company’s borrowings being tied to short-term interest rate indexes, which allows them to reprice upward rapidly in an increasing interest rate environment.
Provision for Loan Losses
The provision for loan losses is a current charge against income and represents an amount which management believes is sufficient to maintain an adequate allowance for known and probable losses in the loan portfolio. In assessing the adequacy of the allowance for loan losses,ALLL, management considers the size and quality of the loan portfolio measured against prevailing economic conditions, regulatory guidelines, and historical loan loss experience. When a determination is made by management to charge off a loan balance, such write-off is charged against the allowance for loan losses.ALLL.
We recorded a provision for loan losses of $1.0$1.6 million in the thirdfirst quarter of 2018,2019, a decrease of $3.4$0.3 million, or 78.3%13.8%, from $4.4$1.9 million for the thirdfirst quarter of 2017.2018. The decrease was primarily due to lower loan growth during first quarter of 2019 compared to the presence of specific provisions on large credits that occurred in 2017 that did not occur in 2018.same period last year. Net loans charged off in the thirdfirst quarter of 20182019 totaled $0.5$1.2 million, compared to $0.4$0.2 million net loans charged off in the thirdfirst quarter of 2017.2018. We determined an appropriate provision based on our evaluation of the adequacy of the allowance for loan lossesALLL in relationship to a continuing review of problem loans, current economic conditions, actual loss experience and industry trends. We believed that the allowance for loan lossesALLL was adequate based on the inherent risk in the portfolio as of September 30, 2018;March 31, 2019; however, there is no assurance losses will not exceed the allowance, and any growth in the loan portfolio and the uncertainty of the general economy may require additional provisions in future periods.
Sensitive assets include nonaccrual loans, loans on the Bank’s watch loan reports and other loans identified as having higher potential for loss. We review sensitive assets on at least a quarterly basis for changes in the customers’ ability to pay and changes in the valuation of underlying collateral in order to estimate probable losses. We also periodically review a watch loan list which is comprised of loans that have been restructured or involve customers in industries which have been adversely affected by market conditions. The majority of these loans are being repaid in conformance with their contracts.

Total noninterest income for the thirdfirst quarter of 2018 increased $0.12019 decreased $0.3 million, or 1.1%4.8%, to $6.0$5.4 million from $5.9$5.7 million in the third quarter of 2017. The greatest increase was in other gain of $0.3 million between the third quarter of 2018 and the third quarter of 2017, due primarily to increased gains on the sale of other real estate owned and derivative income. Other gain (loss) represents gains and losses on the sale other real estate owned, derivatives, premises and equipment, other assets, and the mark-to-market of equity securities. Trust, investment and insurance fees increased $0.1 million, or 5.0%, to $1.5 million for the third quarter of 2018, due to increased trust services activity. These increase were partially offset by a decrease of $0.2 million, or 11.4%, in service charges and fees on deposit accounts to $1.1 million for the third quarter of 2018, compared to $1.3 million for the third

quarter of 2017, primarily due to decreased non-sufficient funds charges on deposit accounts. Other service charges and fees decreased $0.1 million, or 7.6%, to $1.5 million in the third quarter of 2018 from $1.6 million in the third quarter of 2017, primarily due to a cumulative adjustment change in how electronic transaction expenses are classified that was made in the third quarter of 2017. Loan origination and servicing fees decreased $0.1 million, or 12.0%, from $1.0 million for the third quarter of 2017 to $0.9 million for the thirdfirst quarter of 2018. ThisThe greatest decrease was in loan revenue, which decrease was primarily due to a lower level of loans originated and sold on the secondary market in the thirdfirst quarter of 2019 compared to the first quarter of 2018 compared to the third quarter of 2017, which wasas a result of the general decrease in mortgage activitysevere weather experienced in the Company’s markets.
Management’s strategic goal is formarket footprint during the quarter ended March 31, 2019. Service charges and fees decreased primarily due to a decrease in fees related to deposit accounts. These decreases were partially offset by an increase in other noninterest income, due primarily to constitute 25% of total revenues (net interest increased dividends received on FHLB stock and derivative income. Other noninterest

income plus noninterestrepresents primarily gains and losses on derivatives, and the mark-to-market and dividend income excluding gain/loss on securitiesreceived from equity securities. Income from investment services and premises and equipment and impairment of investment securities) over time. For the three months ended September 30, 2018, noninterest income comprised 17.2% of total revenues, compared with 17.8% for the same period in 2017. Despite recent downward trends in this ratio, management expects to see gradual improvement in future periodstrust activities increased due to the implementation of new management strategies in the origination of residential real estate loans, and continued growth in trust,increased investment and insurance fees. We expect this ratio to be positively impacted by the proposed acquisition of ATBancorp.services activity.

Compensation and employee benefits increased $1.0 million, or 8.4%, from $12.0 million for the thirdfirst quarter of 2017 to $13.1 million for the third quarter of 2018,2019 primarily due to normal annual salary and personnelbenefit cost adjustments. The Company also realized an expense of $0.3 million related to the retirement of the Company’s Chief Credit Officer, which was effective August 31, 2018, which expense is included in salariesLegal and employee benefits. Occupancy and equipment expense, net, increased $1.0 million, or 32.3%, to $4.0 million for the third quarter of 2018 compared to $3.0 million for the third quarter of 2017, due primarily to a $0.6 million writedown of the value of a former branch facility that is currently listed for sale. Professionalprofessional fees increased $0.9 million, or 99.5%, for the quarter ended September 30, 2018March 31, 2019 compared to the quarter ended September 30, 2017,March 31, 2018, mainly due to expenses paid of $0.6$0.1 million related to the previously announced merger agreement with ATBancorp. Data processing fees also rose primarily due to increased technology expenses related to the Company’s increased focus on customer service technologies. Partially offsetting these increases was a decrease in amortization of intangible assetintangibles, due to normal changes in the rate of expense decreased $0.2 million, or 27.9%, between the two periods.realization.
Income Tax Expense
Our effective income tax rate, or income taxes divided by income before taxes, was 21.0%20.6% for the thirdfirst quarter of 2018,2019, which was lowerhigher than the effective tax rate of 23.4%20.3% for the thirdfirst quarter of 2017.2018. Income tax expense was $1.8$1.9 million in the thirdfirst quarter of 20182019 compared to $1.9$2.0 million for the same period of 2017.2018. The primary reason for the decrease in income tax expense was the reductiona lower level of taxable income being realized in the maximum corporate federal income tax rate to 21% for 2018 compared to 35% for 2017 as a result of the Tax Act enacted by the U.S. government on December 22, 2017. We also realized $0.4 million of historic tax credits in the thirdfirst quarter of 2017 related to the remodel and restoration of the Company’s headquarters building. We expect the reduction in the federal corporate income tax rate to contribute to higher net income levels in future periods.

Comparison of Operating Results for the Nine Months Ended September 30, 2018 and September 30, 2017
Summary
For the nine months ended September 30, 2018, we earned net income of $22.7 million, compared with $20.3 million for the nine months ended September 30, 2017, an increase of 12.0%. The increase in net income was primarily due to a decrease in the provision for loan losses by $2.6 million, or 39.2%, to $4.1 million, compared to $6.7 million for the first nine months of 2017. This decrease was primarily due to the recognition of individual impairments against certain large credits last year with no similarly large impairments in the nine months ended September 30, 2018. In addition, net interest income increased $1.5 million, or 1.9%, for the first nine months of 2018 compared with the same period of 2017. The Company also realized a $1.7 million decrease in

income tax expense between the nine months ended September 30, 2018 and the same period in 2017, primarily due to the reduction in the maximum corporate federal income tax rate to 21% for 2018 compared to 35% for 2017. Noninterest income increased by $0.3 million, or 1.8%, between the first nine months of 2017 and 2018. These changes were partially offset by a $3.7 million, or 6.1%, increase in noninterest expense between the comparative nine month periods, primarily due to an increase of $1.9 million, or 5.4%, in salaries and employee benefits, primarily due to normal annual salary and personnel adjustments. Our annualized return on average assets for the first nine months of 2018 was 0.94% compared with 0.88% for the same period in 2017. Our annualized return on average shareholders’ equity was 8.84% for the nine months ended September 30, 2018 versus 8.20% for the nine months ended September 30, 2017. The annualized return on average tangible equity was 12.00% for the first nine months of 2018 compared with 11.47% for the same period in 2017.

We have traditionally disclosed certain non-GAAP ratios, including our return on average tangible equity and the ratio of our tangible equity to tangible assets, as well as adjusted noninterest income as a percentage of total revenue and tangible book value per share. We believe these financial measures provide investors with information regarding our financial condition and results of operations and how we evaluate them internally, such as presenting how management tracks adjusted noninterest income as a percentage of total revenue against its goal of 25%.

Net Interest Income
Our net interest income for the nine months ended September 30, 2018, was $79.3 million, up $1.5 million, or 1.9%, from $77.8 million for the nine months ended September 30, 2017, primarily due to an increase of $6.6 million, or 7.5%, in interest income. Loan interest income increased $6.0 million, or 7.9%, to $82.1 million for the first nine months of 2018 compared to the first nine months of 2017, primarily due to a $157.1 million, or 7.2%, increase in the average balance of loans between the two periods. Loan interest income in 2018 also included the effect of a decrease in the discount accretion related to the merger in 2015 of the Company with Central Bancshares, Inc. (“Central”), to $2.3 million for the nine months ended September 30, 2018, compared to $3.8 million for the nine months ended September 30, 2017. Interest income on investment securities rose $0.6 million, or 5.2%, to $13.2 million for the first nine months of 2018 compared to the first nine months of 2017 primarily due to an increase of $1.8 million in the average balance between the comparative periods. These income increases were partially offset by an increase of $5.2 million, or 46.8%, in interest expense, to $16.2 million for the nine months ended September 30, 2018, compared to $11.0 million for the first nine months of 2017. Interest expense on deposits increased $3.8 million, or 45.4%, to $12.2 million for the nine months ended September 30, 2018 compared to $8.4 million for the nine months ended September 30, 2017, as the average rate for deposits increased 21 basis points, and the average balance of interest-bearing deposits increased $128.3 million, or 6.4%, between the two periods. Interest expense related to borrowings rose $1.4 million, or 51.0% between the two periods, primarily due to a 42 basis point increase in average rate for the first nine months of 2018 compared to the same period of 2017.
The Company posted a net interest margin, calculated on a fully tax-equivalent basis, of 3.64% for the first nine months of 2018, down 21 basis points from the net interest margin of 3.85% for the same period in 2017. For the first nine months of 2018 compared with 2017, the tax equivalent loan yield was unchanged between the two period, on a higher volume of average loans, coupled with a 15 basis point tax equivalent yield decrease on a higher average balance of investment securities, resulted in an overall 1 basis point decrease in the yield on earning assets. On the liability side of the balance sheet, a 21 basis point increase in

the cost of deposit was due primarily to the increasing interest rate environment. This, combined with an increase in the cost of borrowed funds of 42 basis points, were the primary factors in a 23 basis point increase in the cost of interest-bearing liabilities for the first nine months of 2018 compared to the same period of 2017.
The following table shows consolidated average balance sheets, detailing the major categories of assets and liabilities, the interest income earned on interest-earning assets, the interest expense paid for interest-bearing liabilities, and the related yields and interest rates for the nine months ended September 30, 2018 and 2017, reported on a fully tax-equivalent basis assuming a 21% tax rate for 2018 and a 35% tax rate for 2017. Dividing annualized income or expense by the average balances of assets or liabilities results in average yields or costs. Average information is provided on a daily average basis.

(1)Non-accrual loans have been included in average loans, net of unearned income. Amortized net deferred loans and net unearned discounts on acquired loans were included in the interest income calculations. The amortization of net deferred loans fees was $(339) thousand, and $(411) thousand for the nine months ended September 30, 2018, and September 30, 2017, respectively. Accretion of unearned purchase discounts was $2.3 million and $3.8 million for the nine months ended September 30, 2018, and September 30, 2017, respectively.
(2)Computed on a tax-equivalent basis, assuming a federal income tax rate of 21% for 2018 and 35% for 2017.
(3)Net interest margin is tax-equivalent net interest income as a percentage of average interest-earning assets.

The following table sets forth an analysis of volume and rate changes in interest income and interest expense on our average interest-earning assets and average interest-bearing liabilities during the nine months ended September 30, 2018,2019 compared to the same period in 2017, reported on a fully tax-equivalent basis assuming a 21% tax rate for 2018 and a 35% tax rate for 2017. The table distinguishes between the changes related to average outstanding balances (changes in volume holding the initial interest rate constant) and the changes related to average interest rates (changes in average rate holding the initial outstanding balance constant). The change in interest due to both volume and rate has been allocated to volume and rate changes in proportion to the relationship of the absolute dollar amounts of the change in each.

Interest income and fees on loans on a tax-equivalent basis increased $5.5 million, or 7.1%, in the first nine months of 2018 compared to the same period in 2017. This increase reflects the effect of the merger-related discount accretion for loans of $2.3 million in the first nine months of 2018, compared to $3.8 million of discount accretion in the first nine months of 2017. The increased income is due to average loan balances increasing $157.1 million, or 7.2%, for the first nine months of 2018 compared to the same period in 2017, primarily resulting from loan originations exceeding loan payments and payoffs. The yield on loans in the first nine months of 2017 was 4.74%, the same as in the first nine months of 2018. The yield on our loan portfolio is affected by the amount of nonaccrual loans (which do not earn interest income), the mix of the portfolio (real estate loans generally have a lower overall yield than commercial and agricultural loans), the effects of competition and the interest rate environment on the amounts and volumes of new loan originations, and the mix of variable-rate versus fixed-rate loans in our portfolio. Despite the increase in overall interest rates, we expect the yield on new and renewing loans to remain relatively flat in the markets we serve due to competitive pressures for quality credits.
Interest income on investment securities on a tax-equivalent basis totaled $14.4 million in the first nine months of 2018 compared with $15.1 million for the same period of 2017. The tax-equivalent yield on our investment portfolio for the first nine months of 2018 decreased to 2.98% from 3.13% in the comparable period of 2017, primarily due to the impact of the reduction in the federal corporate income tax rate from 35% in 2017 to 21% in 2018. The average balance of investments in the first nine months of 2018 was $645.8 million compared with $644.0 million in the first nine months of 2017, an increase of $1.8 million, or 0.3%.
Interest expense on deposits was $12.2 million for the first nine months of 2018 compared with $8.4 million for the same period in 2017. This increase was primarily due to the increase in general interest rates. Additionally, average interest-bearing deposits for the first nine months of 2018 increased $128.3 million, or 6.4%, compared with the same period in 2017, due primarily to an increased focus by the Company on gathering new deposits. The weighted average rate paid on interest-bearing deposits was 0.76% for the first nine months of 2018 compared with 0.55% for the first nine months of 2017. We expect to see some upward movement in deposit rates in future periods, as overall interest rate increases continue in our market footprint due to competition for deposits.

Interest expense on borrowed funds in the first nine months of 2018 was $4.0 million, compared with $2.6 million for the same period in 2017, an increase of $1.4 million, or 51.0%. Average borrowed funds for the first nine months of 2018 were $43.2 million higher compared with the same period in 2017. The increase in the average level of FHLB borrowings of $28.1 million, or 26.9%, coupled with an increase in the average balance of federal funds purchased and repurchase agreements of $20.0 million, or 23.5%, was partially offset by a $5.0 million, or 12.1%, decrease in long-term debt and junior subordinated notes, all for the first nine months of 2018 compared to the first nine months of 2017. The weighted average rate on borrowed funds for the first nine months of 2018 was 1.95%, an increase of 42 basis points from 1.53% for the first nine months of 2017. The increase in the weighted average rate was due to the interest rate on a portion of the Company’s borrowings being tied to short-term interest rate indexes, which allows them to reprice upward rapidly in an increasing interest rate environment.
Provision for Loan Losses
We recorded a provision for loan losses of $4.1 million in the first nine months of 2018, compared to $6.7 million for the same period of 2017, a decrease of $2.6 million, or 39.2%. The decreased provision was primarily due to the presence of specific provisions on large credits that occurred in 2017 that did not occur in 2018. Net loans charged off in the first nine months of 2018 totaled $0.8 million compared with $2.0 million in the first nine months of 2017.

In the first nine months of 2018 total noninterest income increased $0.3 million, or 1.8%, to $17.1 million from $16.8 million during the same period of 2017. This increase was primarily due to an increase in other gain of $0.3 million, to $0.3 million for the nine months ended September 30, 2018 compared to $0.1 million for the same period of 2017. This increase was primarily due to increased gains on the sale of other real estate owned and derivative income. Loan origination and servicing fees increased $0.2 million, or 8.1%, between the first nine months of 2018 and the same period of 2017. This increase was primarily due to the recovery of interest and collection expenses on a charged-off loan in the amount of $0.2 million in the first quarter of 2018 and $0.1 million of income related to the mark-to-market of our loan servicing portfolio, and despite a lower level of loans originated and sold on the secondary market for the first nine months of 2018 compared to the first nine months of 2017, a result of the general decrease in mortgage activity in the Company’s markets. Bank-owned life insurance income increased $0.2 million between the comparative 2017 and 2018 periods due to the purchase of an additional $11.2 million of insurance in the fourth quarter of 2017. Trust, investment and insurance fees increased $0.1 million, or 2.4%, to $4.7 million for the first nine months of 2018, due to increased trust services activity. These increases were partially offset by a decrease in service charges and fees on deposit accounts, which decreased $0.3 million, or 9.4%, to $3.5 million for the first nine months of 2018 compared with $3.8 million for the same period in 2017, primarily due to decreased non-sufficient funds charges on deposit accounts. Other service charges and fees decreased $0.1 million, or 2.5%, in the nine months ended September 30, 2018 compared to the same period of 2017, primarily due to a cumulative adjustment change in how electronic transaction expenses are classified that was made in the third quarter of 2017.
Management’s strategic goal is for noninterest income to constitute 25% of total revenues (net interest income plus noninterest income excluding gain/loss on securities and premises and equipment and impairment of investment securities) over time. For the nine months ended September 30, 2018, noninterest income comprised 17.3% of total revenues, compared with 17.5% for the same period in 2017. Despite recent downward trends in this ratio, management expects to see continued gradual improvement in future periods due to the implementation of new management strategies in the origination of residential real estate loans, and continued growth in trust, investment and insurance fees. We expect this ratio to be positively impacted by the proposed acquisition of ATBancorp.

Noninterest expense increased to $63.7 million for the nine months ended September 30, 2018, compared with $60.0 million for the nine months ended September 30, 2017, an increase of $3.7 million, or 6.1%, with salaries and employee benefits showing the greatest increase of $1.9 million, or 5.4%, from $35.7 million for the nine months ended September 30, 2017, to $37.6 million for the nine months ended September 30, 2018, primarily due to normal annual salary and personnel adjustments. The Company also realized an expense of $0.3 million related to the retirement of the Company’s Chief Credit Officer, which was effective August 31, 2018, which was included in salaries and employee benefits. Occupancy and equipment expense increased $1.1 million, or 12.0%, primarily due to the previously mentioned $0.6 million writedown of the value of a former branch facility that is currently listed for sale. Professional fees increased $0.6 million, or 20.8%, for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017, mainly due to expenses paid of $0.6 million related to the previously announced merger agreement with ATBancorp. Data processing expense rose $0.1 million, or 4.7%, for the nine months ended September 30, 2018, compared to the nine months ended September 30, 2017. Partially offsetting these increases, amortization of intangible asset expense decreased $0.6 million, or 25.7%, for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017.
Income Tax Expense
Our effective tax rate, or income taxes divided by income before taxes, was 20.7% for the first nine months of 2018, and 27.3% for the first nine months of 2017. Income tax expense decreased to $5.9 million in the first nine months of 2018 compared with $7.6 million for the same period of 2017, primarily due to the reduction in the maximum corporate federal income tax rate to 21% for 2018 compared to 35% for 2017 as a result of the Tax Act enacted by the U.S. government on December 22, 2017. We expect the reduction in the federal corporate income tax rate to contribute to higher net income levels in future periods.

FINANCIAL CONDITION
Our total assets were $3.27$3.31 billion at September 30, 2018,March 31, 2019, an increase of $55.7$17.5 million, or 1.7%0.5%, from December 31, 2017.2018.

These increases were partially offset by a decrease in investment securitiescash and cash equivalents of $41.0$2.5 million, or 6.4%5.5%. Total deposits at September 30, 2018,March 31, 2019, were $2.63$2.68 billion, an increase of $26.9$71.9 million from December 31, 2017.2018.

These increases were partially offset by a decrease of $3.4$12.4 million, or 0.7%2.8%, in non-interest-bearing demand deposits, and a decrease of $1.8$9.4 million, or 0.9%4.5%, in savings deposits. Between December 31, 20172018 and September 30, 2018, federal funds purchased rose $18.1 million, to $19.1 million compared to $1.0 million, while securities sold under agreements to repurchaseMarch 31, 2019, short-term borrowings declined $27.3 million, due to normal cash need fluctuations by customers. FHLB borrowings rose $28.0$55.4 million, or 24.3%42.1%, while long-term debt decreased $6.3 million, or 3.7%, between the two dates. The overall increasedecrease in borrowings was the result of deposit growth exceeding growth in the loan portfolio exceeding deposit growth. At September 30, 2018, long-term debt had an outstanding balance of $8.8 million, a decrease of $3.8 million, or 30.0%, from December 31, 2017, due to normal scheduled repayments.portfolio.

Loan Review and Classification Process for Agricultural, Commercial and Industrial, and Commercial Real Estate Loans:
The Bank maintains a loan review and classification process which involves multiple officers of the Bank and is designed to assess the general quality of credit underwriting and to promote early identification of potential problem loans. All commercial and agricultural loan officers are charged with the responsibility of risk rating all loans in their portfolios and updating the ratings, positively or negatively, on an ongoing basis as conditions warrant. Risk ratings are selected from an 8-point scale with ratings as follows: ratings 1- 4 Satisfactory (pass), rating 5 Watch (potential weakness), rating 6 Substandard (well-defined weakness), rating 7 Doubtful, and rating 8 Loss.
When a loan officer originates a new loan, based upon proper loan authorization, he or she documents the credit file with an offering sheet summary, supplemental underwriting analysis, relevant financial information and collateral evaluations. All of this information is used in the determination of the initial loan risk rating. The Bank’s loan review department undertakes independent credit reviews of relationships based on either criteria established by loan policy, risk-focused sampling, or random sampling. Loan policy requires all lending relationships with total exposure of $5.0 million or more as well as all classified (loan grades 6 through 8) and watch (loan grade 5) rated credits over $1.0 million be reviewed no less than annually. The individual loan reviews consider such items as: loan type; nature, type and estimated value of collateral; borrower and/or guarantor estimated financial strength; most recently available financial information; related loans and total borrower exposure; and current and anticipated performance of the loan. The results of such reviews are presented to executive management.
Through the review of delinquency reports, updated financial statements or other relevant information, the lending officer and/or loan review personnel may determine that a loan relationship has weakened to the point that a watch (loan grade 5) or classified (loan grades 6 through 8) status is warranted. When a loan relationship with total related exposure of $1.0 million or greater is adversely graded (loan grade 5 or above), or is classified as a TDR (regardless of size), the lending officer is then charged with preparing a loan strategy summary worksheet that outlines the background of the credit problem, current repayment status of the loans, current collateral evaluation and a workout plan of action. This plan may include goals to improve the credit rating, assist the borrower in moving the loans to another institution and/or collateral liquidation. All such reports are first presented to regional management and then to the loan strategy committee. Copies of the minutes of these committee meetings are presented to the board of directors of the Bank.
Depending upon the individual facts and circumstances and the result of the classified/watch review process, loan officers and/or loan review personnel may categorize the loan relationship as impaired. Once that determination has occurred, the credit analyst will complete an evaluation of the collateral (for collateral-dependent loans) based upon the estimated collateral value, adjusting for current market conditions and other local factors that may affect collateral value. Loan review personnel may also complete an independent impairment analysis when deemed necessary. These judgmental evaluations may produce an initial specific allowance for placement in the Company’s allowance for loan and lease losses calculation. Impairment analysis for the underlying collateral value is completed in the last month of the quarter.   The impairment analysis worksheets are reviewed by the Credit Administration department prior to quarter-end. The board of directors of the Bank on a quarterly basis reviews the classified/watch reports including changes in credit grades of 5 or higher as well as all impaired loans, the related allowances and OREO.foreclosed assets, net.
In general, once the specific allowance has been finalized, regional and executive management will consider a charge-off prior to the calendar quarter-end in which that reserve calculation is finalized.
The review process also provides for the upgrade of loans that show improvement since the last review. All requests for an upgrade of a credit are approved by the loan strategy committee before the rating can be changed.

Restructured Loans
We restructure loans for our customers who appear to be able to meet the terms of their loan over the long term, but who may be unable to meet the terms of the loan in the near term due to individual circumstances. We consider the customer’s past performance, previous and current credit history, the individual circumstances surrounding the current difficulties and their plan to meet the terms of the loan in the future prior to restructuring the terms of the loan. The following factors are indicators that a concession has been granted (one or multiple items may be present):
The borrower receives a reduction of the stated interest rate for the remaining original life of the debt.
The borrower receives an extension of the maturity date or dates at a stated interest rate lower than the current market interest rate for new debt with similar risk characteristics.
The borrower receives a reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement.
The borrower receives a deferral of required payments (principal and/or interest).
The borrower receives a reduction of the accrued interest.
Generally, loans are restructured through short-term interest rate relief, short-term principal payment relief or short-term principal and interest payment relief. Once a restructured loan has gone 90 days or more past due or is placed on nonaccrual status, it is included in the 90 days or more past due or nonaccrual totals.
During the ninethree months ended September 30, 2018,March 31, 2019, the Company restructured one loanno loans by granting concessions to a borrower experiencing financial difficulties.
A loan classified as a troubled debt restructuring will no longer be included in the troubled debt restructuring disclosures in the periods after the restructuring if the loan performs in accordance with the terms specified by the restructuring agreement and the interest rate specified in the restructuring agreement represents a market rate at the time of modification. The specified interest rate is considered a market rate when the interest rate is equal to or greater than the rate the Company is willing to accept at the time of restructuring for a new loan with comparable risk. If there are concerns that the borrower will not be able to meet the modified terms of the loan, the loan will continue to be included in the troubled debt restructuring disclosures.
We consider all TDRs, regardless of whether they are performing in accordance with their modified terms, to be impaired loans when determining our allowance for loan losses. A summary of restructured loans as of September 30, 2018 and December 31, 2017 is as follows:

Allowance for Loan Losses
The ALLL is an accounting estimate of incurred credit losses in our loan portfolio at the balance sheet date. The provision for loan losses is the expense recognized in the consolidated statements of income to adjust the allowance to the levels deemed appropriate by management, as measured by the Company’s credit loss estimation methodologies.
Our ALLL as of September 30, 2018March 31, 2019 was $31.3$29.7 million, which was 1.32%1.23% of total loans held for investment, net of unearned income, as of that date. This compares with an ALLL of $28.1$29.3 million as of December 31, 2017,2018, which was 1.23%1.22% of total loans held for investment, net of unearned income, as of that date. Gross charge-offs for the first ninethree months of 20182019 totaled $1.6$1.4 million, while there were $0.8$0.1 million in recoveries of previously charged-off loans. The increase in the allowance for loan lossesALLL was primarily due to loan growth (excluding loans held for sale) of $91.0$5.0 million for the ninethree months ended September 30, 2018,March 31, 2019, combined with some indicated weakness innet charge-offs experienced during the agricultural sector.period and the recognition of small impairments on several credit relationships. The ratio of annualized net loan charge offs to average loans for the first ninethree months of 20182019 was 0.05%0.21% compared to 0.51%0.26% for the year ended December 31, 2017.2018. As of September 30, 2018,March 31, 2019, the ALLL was 109.9%111.3% of nonperforming loans compared with 117.6%114.6% as of December 31, 2017.2018. Based on the inherent risk in the loan portfolio, management believed that as of September 30, 2018,March 31, 2019, the ALLL was adequate; however, there is no assurance losses will not exceed the allowance, and any growth in the loan portfolio or uncertainty in the general economy will require that management continue to evaluate the adequacy of the ALLL and make additional provisions in future periods as deemed necessary.
The Bank carefully monitors the loan portfolio and continues to emphasize the importance of credit quality while continuously strengthening loan monitoring systems and controls. The Bank reviews the ALLL quantitative and qualitative methodology on a quarterly basis and makes adjustments when appropriate to maintain adequate reserves. There were no changes to our ALLL calculation methodology during the first ninethree months of 2018.2019. Classified and impaired loans are reviewed per the requirements of FASB ASC Topic 310.
The Bank uses a rolling 20-quarter annual average historical net charge-off component for its ALLL calculation. One qualitative factor table is used for the entire bank. Differences in regional (Iowa, Minnesota/Wisconsin, Florida and Colorado)

economic and business conditions are included in the qualitative factor narrative and the risk is spread over the entire loan portfolio. All pass rated loans, regardless of size, are allocated based on delinquency status. The Bank has streamlined the ALLL process for a number of low-balance loan types that do not have a material impact on the overall calculation, which are applied a reserve amount equal to the overall reserve calculated pursuant to applicable accounting standards to total loan calculated pursuant to applicable accounting standards. The guaranteed portion of any government guaranteed loan is included in the calculation and is reserved for according to the type of loan. Special mention/watch and substandard rated credits not individually reviewed for impairment are allocated at a higher amount due to the inherent risks associated with these types of loans. Special mention/watch risk rated loans (i.e. early stages of financial deterioration, technical exceptions, etc.) are reserved at a level that will cover losses above a pass allocation for loans that had a loss in the trailing 20-quarters in which the loan was risk-rated special mention/watch at the time of the loss. Substandard loans carry a greater risk than special mention/watch loans, and as such, this subset is reserved at a level that covers losses above a pass allocation for loans that had a loss in the trailing 20-quarters in which the loans was risk-rated substandard at the time of the loss. Classified and impaired loans are reviewed per the requirements of applicable accounting standards.
We monitor the loan to value (“LTV”) ratio of all loans in our portfolio, and those loans in excess of internal and supervisory guidelines are presented to the Bank’s board of directors on a quarterly basis. At September 30, 2018,March 31, 2019, there were 2520 owner-occupied 1-4 family loans with a LTV ratio of 100% or greater. In addition, there were 12499 home equity loans without credit enhancement that had a LTV ratio of 100% or greater. We have the first lien on 63 of these equity loans, and other financial institutions have the first lien on the remaining 118.96. Additionally, there were 165168 commercial real estate loans without credit enhancement that exceeded the supervisory LTV guidelines. No additional allocation of the ALLL is made for loans that exceed internal and supervisory guidelines.
We review all impaired and nonperforming loans individually on a quarterly basis to determine their level of impairment due to collateral deficiency or insufficient cash-flow based on a discounted cash-flow analysis. At September 30, 2018,March 31, 2019, TDRs were not a material portion of the loan portfolio. We review loans 90 days or more past due that are still accruing interest no less than quarterly to determine if there is a strong reason that the credit should not be placed on non-accrual. The Bank’s board of directors

has reviewed these credit relationships and determined that these loans and the risks associated with them were acceptable and did not represent any undue risk.
Capital Resources
Total shareholders’ equity was $349.2$363.8 million as of September 30, 2018,March 31, 2019, compared to $340.3$357.1 million as of December 31, 2017,2018, an increase of $8.9$6.8 million, or 2.6%1.9%. This increase was primarily attributable to net income of $22.7$7.3 million for the first ninethree months of 2018. This increase was partially offset by the payment of $7.2 million in common stock dividends,2019, and a $6.5$3.0 million decreaseincrease in accumulated other comprehensive income due to market value adjustments on investment securities available for sale.AFS. This increase was partially offset by the payment of $2.5 million in common stock dividends. In addition, there was a $0.4$0.8 million increase in treasury stock due to the repurchase of 33,99849,216 shares of Company common stock at a cost of $1.1$1.3 million, partially offset by the issuance of 35,49422,246 shares of Company common stock in connection with stock compensation plans during the first ninethree months of 2018.2019. The total shareholders’ equity to total assets ratio was 10.69%11.00% at September 30, 2018,March 31, 2019, up from 10.59%10.85% at December 31, 2017.2018. The tangible equity to tangible assets ratio (a non-GAAP financial measure) was 8.61%8.97% at September 30, 2018,March 31, 2019, compared with 8.44%8.80% at December 31, 2017.2018. Book value was $28.57$29.94 per share at September 30, 2018,March 31, 2019, an increase from $27.85$29.32 per share at December 31, 2017.2018. Tangible book value per share (a non-GAAP financial measure) was $22.50$23.89 at September 30, 2018,March 31, 2019, an increase from $21.67$23.25 per share at December 31, 2017.2018.
Our Tier 1 capital to risk-weighted assets ratio was 11.06%11.21% as of September 30, 2018March 31, 2019 and was 10.96%11.18% as of December 31, 2017.2018. Risk-based capital guidelines require the classification of assets and some off-balance-sheet items in terms of credit-risk exposure and the measuring of capital as a percentage of the risk-adjusted asset totals. Management believed that, as of September 30, 2018,March 31, 2019, the Company and the Bank met all capital adequacy requirements to which we were subject. As of that date, the Bank was “well capitalized” under regulatory prompt corrective action provisions.
The Company See Note 14. “Regulatory Capital Requirements and the Bank are subjectRestrictions on Subsidiary Cash” to the Basel III regulatory capital reforms (the “Basel III Rules”) and the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”). The Basel III Rules are applicableour consolidated financial statements for additional information related 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 $3 billion which are not publicly traded companies). In order to be a “well-capitalized” depository institution, a bank must maintain a Common Equity Tier 1 capital ratio of 6.5% or more; a Tier 1 capital ratio of 8% or more; a Total capital ratio of 10% or more; and a leverage ratio of 5% or more. A capital conservation buffer, comprised of Common Equity Tier 1 capital, is also established above the regulatory minimum capital requirements. This capital conservation buffer is being phased in, which began January 1, 2016 at 0.625% of risk-weighted assets, was 1.25% of risk-weighted assets in 2017, is 1.875% of risk-weighted assets in 2018, and further increases to the final level of 2.5% on January 1, 2019. At

September 30, 2018, the Company’s institution-specific capital conservation buffer necessary to avoid limitations on distributions and discretionary bonus payments was 4.18%, while the Bank’s was 3.97%.
We have traditionally disclosed certain non-GAAP ratios and amounts to evaluate and measure our financial condition, including our Tier 1 capital to risk-weighted assets ratio and our Common Equity Tier 1 capital ratio to risk-weighted assets ratio. We believe these ratios provide investors with information regarding our financial condition and how we evaluate our financial condition internally. The following table provides a reconciliation of these non-GAAP measures to the most comparable GAAP equivalents.

Liquidity
Liquidity management involves meeting the cash flow requirements of depositors and borrowers. We conduct liquidity management on both a daily and long-term basis, and adjust our investments in liquid assets based on expected loan demand, projected loan maturities and payments, expected deposit flows, yields available on interest-bearing deposits, and the objectives of our asset/liability management program. We had liquid assets (cash and cash equivalents) of $53.4$43.0 million as of September 30, 2018,March 31, 2019, compared with $51.0$45.5 million as of December 31, 2017.2018. Interest-bearing deposits in banks at September 30, 2018,March 31, 2019, were $4.2$3.0 million, a decreasean increase of $1.3 million from $5.5$1.7 million at December 31, 2017.2018. Debt securities classified as available for sale,AFS, totaling $407.8$433.0 million and $445.3$414.1 million as of September 30, 2018March 31, 2019 and December 31, 2017,2018, respectively, could be sold to meet liquidity needs if necessary. Additionally, the Bank maintains unsecured lines of credit with several correspondent banks and secured lines with the Federal Reserve Bank Discount Window and the FHLB that would allow us to borrow funds on a short-term basis, if necessary. Management believed that the Company had sufficient liquidity as of September 30, 2018March 31, 2019 to meet the needs of borrowers and depositors.
Our principal sources of funds between December 31, 20172018 and September 30, 2018March 31, 2019 were FHLB borrowings, deposits and federal funds purchased.FHLB borrowings. While scheduled loan amortization and maturing interest-bearing deposits in banks are relatively predictable sources of funds, deposit flows and loan prepayments are greatly influenced by economic conditions, the general level of interest rates, and competition. We utilize particular sources of funds based on comparative costs and availability. This includes fixed-rate FHLB borrowings that can at times be obtained at a more favorable cost than deposits of comparable maturity. We generally manage the pricing of our deposits to maintain a steady deposit base but from time to time may decide, as we have done in the past, not to pay rates on deposits as high as our competition.
As of September 30, 2018,March 31, 2019, we had $8.8$6.3 million of long-term debt outstanding to an unaffiliated banking organization. See Note 10. “Federal Home Loan Bank Borrowings and Long-Term11. “Long-Term Debt” to our consolidated financial statements for additional information related to our long-term debt. We also have $23.9 million of indebtedness payable under junior subordinated debentures issued to subsidiary trusts that issued trust preferred securities in pooled offerings. See Note 9.10. “Junior Subordinated Notes Issued to Capital Trusts” to our consolidated financial statements for additional information related to our junior subordinated notes.
Inflation
The effects of price changes and inflation can vary substantially for most financial institutions. While management believes that inflation affects the growth of total assets, it is difficult to assess its overall impact on the Company. The price of one or more of the components of the Consumer Price Index (“CPI”) may fluctuate considerably and thereby influence the overall CPI without having a corresponding effect on interest rates or upon the cost of those goods and services normally purchased by us. In years of

high inflation and high interest rates, intermediate and long-term interest rates tend to increase, thereby adversely impacting the market values of investment securities, mortgage loans and other long-term fixed rate loans held by financial institutions. In addition, higher short-term interest rates caused by inflation tend to increase financial institutions’ cost of funds. In other years, the reverse situation may occur.
Off-Balance-Sheet Arrangements
We are a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of our customers, which include commitments to extend credit, standby and performance letters of credit, and commitments to originate residential mortgage loans held for sale. Commitments to extend credit are agreements to lend to customers at predetermined interest rates, as long as there is no violation of any condition established in the contracts. Our exposure to credit loss in the event of nonperformance by the other party to the commitments to extend credit is represented by the contractual amount of those instruments. We use the same credit policies in making off-balance-sheet commitments as we do for on-balance-sheet instruments.
Commitments to extend credit 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. We evaluate each customer’s creditworthiness on a case-by-case basis. As of September 30, 2018,March 31, 2019, outstanding commitments to extend credit totaled approximately $511.9$530.7 million.
Commitments under standby and performance letters of credit outstanding totaled $15.5$16.0 million as of September 30, 2018.March 31, 2019. We do not anticipate any losses as a result of these transactions, and expect to have sufficient liquidity to fulfill outstanding credit commitments and letters of credit.

Residential mortgage loans sold to others are predominantly conventional residential first lien mortgages originated under our usual underwriting procedures, and are most often sold on a nonrecourse basis. At September 30, 2018March 31, 2019, there were approximately $1.1$0.3 million of mandatory commitments with investors to sell not yet originated residential mortgage loans. We do not anticipate any losses as a result of these transactions.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.
In general, market risk is the risk of change in asset values due to movements in underlying market rates and prices. Interest rate risk is the risk to earnings and capital arising from movements in interest rates. Interest rate risk is the most significant market risk affecting the Company as other types of market risk, such as foreign currency exchange rate risk and commodity price risk, play a lesser role in the normal course of our business activities.
In addition to interest rate risk, economic conditions in recent years have made liquidity risk (in particular, funding liquidity risk) a more prevalent concern among financial institutions. In general, liquidity risk is the risk of being unable to fund an entity’s obligations to creditors (including, in the case of banks, obligations to depositors) as such obligations become due or to fund its acquisition of assets.
Liquidity Risk
Liquidity refers to our ability to fund operations, to meet depositor withdrawals, to provide for our customers’ credit needs, and to meet maturing obligations and existing commitments. Our liquidity principally depends on cash flows from operating activities, investment in and maturity of assets, changes in balances of deposits and borrowings, and our ability to borrow funds.
Net cash inflows from operating activities were $31.0$11.7 million in the three months of 2019, compared with $11.4 million in the first ninethree months of 2018, compared with $34.0 million in the first nine months of 2017.2018. Net income before depreciation, amortization, and accretion is generally the primary contributor for net cash inflows from operating activities.
Net cash outflows from investing activities were $62.4$20.6 million in the first ninethree months of 2018,2019, compared to net cash outflows of $76.5$46.0 million in the comparable nine-monththree-month period of 2017.2018. In the first ninethree months of 2018,2019, net cash outflows related to the net increase in loans were $92.3$6.4 million for the first ninethree months of 2018,2019, compared with $100.9$40.1 million of net cash outflows for the same period of 2017.2018. Investment securities transactions resulted in net cash inflowsoutflows of $31.7$14.1 million, compared to inflowsoutflows of $24.2$5.3 million during the same period of 2017.2018.

Net cash inflows from financing activities in the first ninethree months of 20182019 were $33.8$6.5 million, compared with net cash inflows of $41.4$26.0 million for the same period of 2017.2018. The largest financing cash inflows during the ninethree months ended September 30, 2018March 31, 2019 were a net increase of $28.0 million in FHLB borrowings, an increase of $26.9$71.9 million in deposits, and an increase of $18.1 million in federal funds purchased.deposits. Uses of cash were highlighted by a decrease of $27.3$49.7 million in FHLB advances, a decrease of $5.8 million in securities sold under agreements to repurchase, $7.2a net decrease of $5.0 million in FHLB borrowings, and $2.5 million to pay dividends, and $3.8 million of payments on long-term debt.dividends.
To further mitigate liquidity risk, the Bank has several sources of liquidity in place to maximize funding availability and increase the diversification of funding sources. The criteria for evaluating the use of these sources include volume concentration (percentage of liabilities), cost, volatility, and the fit with the current asset/liability management plan. These acceptable sources of liquidity include:
Federal Funds Lines and FHLB Advances
Federal Reserve Bank Discount Window
FHLB Borrowings
Brokered Deposits
Brokered Repurchase Agreements
Federal ReserveHome Loan Bank Discount Window
Advances and Federal Funds Lines:
Routine liquidity requirements are met by fluctuations in the FHLB advances and federal funds positionpositions of the Bank. The principal function of these funds is to maintain short-term liquidity. Unsecured federal funds purchased and secured FHLB advance lines are viewed as a volatile liability and are not used as a long-term funding solution, especially when used to fund long-term assets. FHLB advances are subject to the same collateral requirements and borrowing limits as set term FHLB borrowing, discussed below. Multiple correspondent relationships are

preferable and federal funds sold exposure to any one customer is continuously monitored. The current federal funds purchased limit is 10% of total assets, or the amount of established federal funds lines, whichever is smaller. Currently, the Bank has unsecured federal funds lines totaling $150.0 million, which lines are tested annually to ensure availability.
Federal Reserve Bank Discount Window:
The Federal Reserve Bank Discount Window is another source of liquidity, particularly during difficult economic times. The Bank has a borrowing capacity with the Federal Reserve Bank of Chicago limited by the amount of municipal securities pledged against the line. As of March 31, 2019, the Bank had municipal securities with an approximate market value of $12.8 million pledged for liquidity purposes, and had a borrowing capacity of $11.5 million.
FHLB Borrowings:
FHLB borrowings provide both a source of liquidity and long-term funding for the Bank. Use of this type of funding is coordinated with both the strategic balance sheet growth projections and interest rate risk profile of the Bank. Factors that are taken into account when contemplating use of FHLB borrowings are the effective interest rate, the collateral requirements, community investment program credits, and the implications and cost of having to purchase incremental FHLB stock. As of September 30, 2018March 31, 2019, the Bank had $143.0131.0 million in outstanding FHLB borrowings, leaving $137.3149.1 million available for liquidity needs, based on collateral capacity. These borrowings are secured by various real estate loans (residential, commercial and agricultural).
Brokered Deposits:
The Bank has brokered certificate of deposit lines and deposit relationships available to help diversify its various funding sources. Brokered deposits offer several benefits relative to other funding sources, such as: maturity structures which cannot be duplicated in the current deposit market, deposit gathering which does not cannibalize the existing deposit base, the unsecured nature of these liabilities, and the ability to quickly generate funds. However, brokered deposits are often viewed as a volatile liability by banking regulators and market participants. This viewpoint, and the desire to not develop a large funding concentration in any one area outside of the Bank’s core market area, is reflected in an internal policy stating that the Bank limit the use of brokered deposits as a funding source to no more than 10% of total assets. Board approval is required to exceed this limit. The Bank will also have to maintain a “well capitalized” standing to access brokered deposits, as an “adequately capitalized” rating would require an FDIC waiver to do so, and an “undercapitalized” rating would prohibit it from using brokered deposits altogether.
Brokered Repurchase Agreements:
Brokered repurchase agreements may be established with approved brokerage firms and banks. Repurchase agreements create rollover risk (the risk that a broker will discontinue the relationship due to market factors) and are not used as a long-term funding solution, especially when used to fund long-term assets. Collateral requirements and availability are evaluated and

monitored. The current policy limit for brokered repurchase agreements is 10% of total assets. There were no outstanding brokered repurchase agreements at September 30, 2018.
Federal Reserve Bank Discount Window:
The Federal Reserve Bank Discount Window is another source of liquidity, particularly during difficult economic times. The Bank has a borrowing capacity with the Federal Reserve Bank of Chicago limited by the amount of municipal securities pledged against the line. As of September 30, 2018, the Bank had municipal securities with an approximate market value of $12.6 million pledged for liquidity purposes, and had a borrowing capacity of $11.4 million.March 31, 2019.
Interest Rate Risk
Interest rate risk is defined as the exposure of net interest income and fair value of financial instruments (interest-earning assets, deposits and borrowings) to movements in interest rates. The Company’s results of operations depend to a large degree on its net interest income and its ability to manage interest rate risk. The Company considers interest rate risk to be one of its more significant market risks. The major sources of the Company'sCompany’s interest rate risk are timing differences in the maturity and re-pricing characteristics of assets and liabilities, changes in the shape of the yield curve, changes in customer behavior and changes in relationships between rate indices (basis risk). Management measures these risks and their impact in various ways, including through the use of income simulation and valuation analyses. The interest rate scenarios used in such analysis may include gradual or rapid changes in interest rates, spread narrowing and widening, yield curve twists and changes in assumptions about customer behavior in various interest rate scenarios. A mismatch between maturities, interest rate sensitivities and prepayment characteristics of assets and liabilities results in interest-rate risk. Like most financial institutions, we have material interest-rate risk exposure to changes in both short-term and long-term interest rates, as well as variable interest rate indices (e.g., the prime rate or LIBOR). There has been no material change in the Company’s interest rate profile between September 30, 2018March 31, 2019 and December 31, 2017.2018. The mix of earning assets and interest-bearing liabilities has remained stable over the period.
The Bank’s asset and liability committee meets regularly and is responsible for reviewing its interest rate sensitivity position and establishing policies to monitor and limit exposure to interest rate risk. Our asset  and  liability  committee  seeks  to  manage interest  rate  risk  under a  variety of rate  environments  by structuring  our balance sheet and off-balance-sheet positions in such a way that changes in interest rates do not have a large negative impact. The risk is monitored and managed within approved policy limits.

We use a third-party service to model and measure our exposure to potential interest rate changes. For various assumed hypothetical  changes  in  market interest  rates,  numerous  other  assumptions  are  made, such  as  prepayment  speeds  on  loans  and securities backed by mortgages, the  slope  of the Treasury yield-curve, the  rates  and volumes of our deposits, and the  rates  and volumes of our loans. There are two primary tools used to evaluate interest rate risk: net interest income simulation and economic value of equity ("EVE").EVE. In addition, interest rate gap is reviewed to monitor asset and liability repricing over various time periods.
Net Interest Income Simulation: 
Management utilizes net interest income simulation models to estimate the near-term effects of changing interest rates on its net interest income. Net interest income simulation involves forecasting net interest income under a variety of scenarios, which include varying the level of interest rates and the shape of the yield curve. Management exercises its best judgment in making assumptions regarding events that management can influence, such as non-contractual deposit re-pricings, and events outside management'smanagement’s control, such as customer behavior on loan and deposit activity and the effect that competition has on both loan and deposit pricing. These assumptions are subjective and, as a result, net interest income simulation results will differ from actual results due to the timing, magnitude and frequency of interest rate changes, changes in market conditions, customer behavior and management strategies, among other factors. We perform various sensitivity analyses on assumptions of deposit attrition and deposit re-pricing.
The following table presents the anticipated effect on net interest income over a twelve month period if short- and long-term interest rates were to sustain an immediate decrease of 100 basis points or 200 basis points, or an immediate increase of 100 basis points or 200 basis points:

As of September 30, 2018, 37.4%March 31, 2019, 39.4% of the Company’s earning asset balances will reprice or are expected to pay down in the next twelve months, and 64.4%41.8% of the Company’s deposit balances are low cost or no cost deposits.
Economic Value of Equity: 

Management also uses EVE to measure risk in the balance sheet that might not be taken into account in the net interest income simulation analysis. Net interest income simulation highlights exposure over a relatively short time period, while EVE analysis incorporates all cash flows over the estimated remaining life of all balance sheet positions. The valuation of the balance sheet, at a point in time, is defined as the discounted present value of asset cash flows minus the discounted present value of liability cash flows. EVE analysis addresses only the current balance sheet and does not incorporate the run-off replacement assumptions that are used in the net interest income simulation model. As with the net interest income simulation model, EVE analysis is based on key assumptions about the timing and variability of balance sheet cash flows and does not take into account any potential responses by management to anticipated changes in interest rates.
Interest Rate Gap: 
The interest rate gap is the difference between interest-earning assets and interest-bearing liabilities re-pricing within a given period and represents the net asset or liability sensitivity at a point in time. An interest rate gap measure could be significantly affected by external factors such as loan prepayments, early withdrawals of deposits, changes in the correlation of various interest-bearing instruments, competition, or a rise or decline in interest rates.

Item 4. Controls and Procedures.
Disclosure Controls and Procedures
Under the supervision and with the participation of certain members of our management, including our chief executive officer and chief financial officer, we completed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of September 30, 2018March 31, 2019. Based on this evaluation, our chief executive officer and chief financial officer have concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report with respect to timely

communication to them and other members of management responsible for preparing periodic reports of material information required to be disclosed in this report as it relates to the Company and our consolidated subsidiaries.
The effectiveness of our or any system of disclosure controls and procedures is subject to certain limitations, including the exercise of judgment in designing, implementing, and evaluating the controls and procedures, the assumptions used in identifying the likelihood of future events, and the inability to eliminate misconduct completely. As a result, there can be no assurance that our disclosure controls and procedures will prevent all errors or fraud or ensure that all material information will be made known to appropriate management in a timely fashion. By their nature, our or any system of disclosure controls and procedures can provide only reasonable assurance regarding management’s control objectives.
Changes in Internal Control over Financial Reporting
There was no change in our internal control over financial reporting during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We implemented internal controls to ensure we adequately evaluated our contracts and properly assessed the impact of new accounting standards related to leases on our financial statements to facilitate its adoption on January 1, 2019. There were no significant changes to our internal control over financial reporting due to the adoption of the new standard.
