NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Summary of Significant Accounting Policies

Basis of Presentation:

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and with instructions for Form 10-Q and Regulation S-X.  These financial statements include all adjustments (consisting of normal recurring accruals) which in the opinion of management are considered necessary for the fair presentation of the financial position and results of operations for the periods shown.  Certain prior year amounts have been reclassified to conform to the current year presentation.  The Company considers that it operates as one business segment, a commercial bank.

Operating results for the nine month period ended September 30, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2017.  For further information, refer to the consolidated financial statements and footnotes thereto included in the Form 10-K Annual Report of Hills Bancorporation and subsidiary (the “Company”) for the year ended December 31, 2016 filed with the Securities Exchange Commission on March 3, 2017.  The consolidated balance sheet as of December 31, 2016, has been derived from the audited consolidated financial statements for that period.

The Company evaluated subsequent events through the filing date of its quarterly report on Form 10-Q with the SEC.

Effect of New Financial Accounting Standards:

In May 2014, The FASB and International Accounting Standards Board (IASB) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of ASU 2014-09 is that a company should recognize revenue to depict the transfer of promised good or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. For financial institutions, significant changes are not expected given that most financial instruments are not in the scope of the accounting standard update. ASU 2014-09 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. In August 2015, FASB issued ASU 2015-14 deferring the effective date for annual periods and interim periods within those annual periods after December 15, 2017. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company has evaluated all of its noninterest income streams and contracts to determine potential impact. The adoption of ASU 2014-09 by the Company will not have a material impact.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 created Subtopic 321-10, Investments-Equity Securities which is applicable to all entities except those in industries that account for substantially all investments at fair value through earnings or the change in net assets. Under this new subtopic, equity securities are generally required to be measured at fair value with unrealized holding gains and losses reflected in net income. ASU 2016-01 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2017. The adoption of ASU 2016-01 by the Company is not expected to have a material impact.

In February 2016, the FASB issued ASU No. 2016-02 (Topic 842), Leases. The ASU provides guidance requiring lessees to recognize right-of-use assets and lease liabilities for all leases other than those that meet the definition of short-term leases. For short-term leases, lessees may elect an accounting policy by class of underlying asset under which these assets and liabilities are not recognized and lease payments are generally recognized over the lease term on a straight-line basis. Under this new ASU, lessees will recognize right-of use assets and lease liabilities for most leases currently accounted for as operating leases under generally accepted accounting principles. For public companies, ASU 2016-02 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is in the process of analyzing a comprehensive list of lease agreements. The adoption of ASU 2016-02 by the Company is not expected to have a material impact.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(Unaudited)

In March 2016, the FASB issued ASU No. 2016-04, Liabilities - Extinguishments of Liabilities (Subtopic 405-20), Recognition of Breakage for Certain Prepaid Stored-Value Products. ASU 2016-04 applies to all entities that offer certain prepaid stored - value products. The ASU provides guidance for the derecognition of financial liabilities related to the issuance of these products and aligns the recognition of breakage to current authoritative guidance. For public companies, ASU 2016-04 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The adoption of ASU 2016-04 by the Company is not expected to have a material impact.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting. The ASU simplifies several aspects of the accounting for share-based payment transaction, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public companies, ASU 2016-09 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The Company adopted ASU 2016-09 for the period ending March 31, 2017. There was no material impact on the financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (CECL). The ASU changes the way entities recognize impairment of financial assets by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. Under the CECL model, we will be required to present certain financial assets carried at amortized cost, such as loans held for investment and held-to-maturity debt securities, at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement will take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the "incurred loss" model required under current GAAP, which delays recognition until it is probable a loss has been incurred. Accordingly, we expect that the adoption of the CECL model will materially affect how we determine our allowance for loan losses and could require us to significantly increase our allowance. For public companies, ASU 2016-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, early adoption is permitted for the fiscal year beginning after December 15, 2018. The Company is in the process of implementing a software solution to assist in the analysis of historical loan data to determine the CECL model that will be implemented. We expect to recognize a one-time cumulative-effect adjustment to our allowance for loan losses as of the beginning of the first reporting period in which the new standard is adopted. The amount of the one-time cumulative-effect adjustment has not yet been determined.

In January 2017, the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments - Equity Method and Joint Ventures (Topic 323), Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings. This ASU adds an SEC paragraph and amends other Topics pursuant to an SEC staff Announcement made at the September 22, 2016 Emerging Issues Task Force (EITF) meeting. The SEC paragraph applies to ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606); ASU No. 2016-02, Leases (Topic 842); and ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU provides that a company should evaluate ASUs that have not yet been adopted to determine the appropriate financial statement disclosures about the potential material effects of those ASUs on the financial statements when adopted. If the company does not know or cannot reasonably estimate the impact that adoption of the ASUs referenced in this announcement is expected to have on the financial statements, then in addition to making a statement to that effect, the company should consider additional qualitative financial statement disclosures to assist the reader in assessing the significance of the impact that the standard will have on the financial statements of the company when adopted. Additional qualitative disclosures should include a description of the effect of the accounting policies that the company expects to apply and a comparison to the company's current accounting policies. Also, the company should describe the status of its process to implement the new standards and the significant implementation matters yet to be addressed.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 250), Simplifying the Test for Goodwill Impairment. The ASU simplifies the goodwill impairment test by requiring a company to perform its annual or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized when the carrying amount exceeds fair value. For public companies, ASU 2017-04 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of ASU No. 2017-04 by the Company is not expected to have a material impact.

In March 2017, the FASB issued ASU No. 2017-08, Receivable - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities. This ASU shortens the amortization period for certain callable debt securities held at a premium. The premium will be amortized to the earliest call date. For public companies, ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2018. The Company adopted ASU 2017-08 for the period ending March 31, 2017. There was no material impact on the financial statements.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. This ASU requires companies to change the recognition and presentation of the effects of hedge accounting by eliminating the requirement to separately measure and report hedge ineffectiveness and requiring companies to present all of the elements of hedge accounting that affect earnings in the same income statement line as the hedged item. Furthermore, the standard eases the requirements for effectiveness testing, hedge documentation and applying the critical terms match method and introduces new alternatives that will permit companies to reduce the risk of material error corrections if they misapply the shortcut method. For public companies, ASU 2017-12 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2018. The adoption of ASU 2017-12 by the Company is not expected to have a material impact.

Note 2. Earnings Per Share

Basic earnings per share is computed using the weighted average number of actual common shares outstanding during the period.  Diluted earnings per share reflects the potential dilution that would occur from the exercise of common stock options outstanding.  ESOP shares are considered outstanding for this calculation unless unearned.

The computation of basic and diluted earnings per share for the periods presented is as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2017			2016			2017		2016
Common shares outstanding at the beginning of the period	9,329,514			9,283,341			9,264,227		9,322,054
Weighted average number of net shares (redeemed) issued	(4,596		)	(7,633		)	64,144		(31,950		)
Weighted average shares outstanding (basic)	9,324,918			9,275,708			9,328,371		9,290,104
Weighted average of potential dilutive shares attributable to stock options granted, computed under the treasury stock method	3,559			6,584			4,874		6,357
Weighted average number of shares (diluted)	9,328,477			9,282,292			9,333,245		9,296,461
Net income (In thousands)	$	8,552		$	9,176		$	23,883	$	24,843

The Company considered the following information in reaching the conclusion that the impairments disclosed in the table above are temporary and not other-than-temporary impairments.  None of the unrealized losses in the above table was due to the deterioration in the credit quality of any of the issues that might result in the non-collection of contractual principal and interest.  The unrealized losses are due to changes in interest rates.  The Company has not recognized any unrealized loss in income because management does not have the intent to sell the securities included in the previous table.  Management has concluded that it is more likely than not that the Company will not be required to sell these securities prior to recovery of the amortized cost basis.

The below are descriptions of the credit quality indicators:

Excellent – Excellent rated loans are prime quality loans covered by highly liquid collateral with generous margins or supported by superior current financial conditions reflecting substantial net worth, relative to total credit extended, and based on assets of a stable and non-speculative nature whose values can be readily verified. Identified repayment source or cash flow is abundant and assured.

Good – Good rated loans are adequately secured by readily marketable collateral or good financial condition characterized by liquidity, flexibility and sound net worth. Loans are supported by sound primary and secondary payment sources and timely and accurate financial information.

Satisfactory – Satisfactory rated loans are loans to borrowers of average financial means not especially vulnerable to changes in economic or other circumstances, where the major support for the extension is sufficient collateral of a marketable nature, and the primary source of repayment is seen to be clear and adequate.

Monitor – Monitor rated loans are identified by management as warranting special attention for a variety of reasons that may bear on ultimate collectability. This may be due to adverse trends, a particular industry, loan structure, or repayment that is dependent on projections, or a one-time occurrence.

Special Mention – Special mention rated loans are supported by a marginal payment capacity and are marginally protected by collateral.  There are identified weaknesses that if not monitored and corrected may adversely affect the Company’s credit position.  A special mention credit would typically have a weakness in one of the general categories (cash flow, collateral position or payment history) but not in all categories.

Substandard – Substandard loans are not adequately supported by the paying capacity of the borrower and may be inadequately collateralized.  These loans have a well-defined weakness or weaknesses.  For these loans, it is more probable than not that the Company could sustain some loss if the deficiency(ies) is not corrected.

(1) There were $3.76 million and $4.23 million of TDR loans included within nonaccrual loans as of September 30, 2017 and December 31, 2016, respectively.

Loans 90 days or more past due that are still accruing interest increased $1.16 million from December 31, 2016 to September 30, 2017 due to an increase in the number of loans past due greater than 90 days including a $1.12 agricultural relationship. As of September 30, 2017 there were 10 accruing loans past due 90 days or more. The average balance of accruing loans past due as of September 30, 2017 are $0.18 million. There were 6 accruing loans past due 90 days or more as of December 31, 2016 and the average loan balance was $0.11 million. The accruing loans past due 90 days or more balances are believed to be adequately collateralized and the Company expects to collect all principal and interest as contractually due under these loans.

The Company may modify the terms of a loan to maximize the collection of amounts due.  Such a modification is considered a troubled debt restructuring (“TDR”).  In most cases, the modification is either a reduction in interest rate, conversion to interest only payments or an extension of the maturity date.  The borrower is experiencing financial difficulties or is expected to experience difficulties in the near-term, so a concessionary modification is granted to the borrower that would otherwise not be considered.  TDR loans accrue interest as long as the borrower complies with the revised terms and conditions and has demonstrated repayment performance at a level commensurate with the modified terms over several payment cycles.

Impaired loans increased $0.12 million from December 31, 2016 to September 30, 2017.  Impaired loans include any loan that has been placed on nonaccrual status, accruing loans past due 90 days or more and TDR loans.  Impaired loans also include loans that, based on management’s evaluation of current information and events, the Company expects to be unable to collect in full according to the contractual terms of the original loan agreement.  Impaired loans were 1.40% of loans held for investment as of September 30, 2017 and 1.48% as of December 31, 2016.  The increase in impaired loans is due mainly to an increase in TDR loans of $3.16 million and an increase in accruing loans past due 90 days or more of $1.16 million from December 31, 2016 to September 30, 2017, and is offset by a decrease in nonaccrual loans of $0.60 million, and a decrease of $3.60 million in relationships with a specific allowance for losses.

The Company regularly reviews a substantial portion of the loans in the portfolio and assesses whether the loans are impaired in accordance with ASC 310.  If the loans are impaired, the Company determines if a specific allowance is appropriate.  In addition, the Company's management also reviews and, where determined necessary, provides allowances for particular loans based upon (1) reviews of specific borrowers and (2) management’s assessment of areas that management considers are of higher credit risk, including loans that have been restructured.  Loans that are determined not to be impaired and for which there are no specific allowances are classified into one or more risk categories. Based upon the risk category assigned, the Company allocates a percentage, as determined by management, for a required allowance needed.  The determination of the appropriate percentage begins with historical loss experience factors, which are then adjusted for levels and trends in past due loans, levels and trends in charged-off and recovered loans, trends in volume growth, trends in problem and watch loans, trends in restructured loans, local economic trends and conditions, industry and other conditions, and effects of changing interest rates.

Specific allowances for losses on impaired loans are established if the loan balances exceed the net present value of the relevant future cash flows or the fair value of the relevant collateral based on updated appraisals and/or updated collateral analysis for the properties if the loan is collateral dependent.  The Company may recognize a charge off or record a specific allowance related to an impaired loan if there is a collateral shortfall or it is unlikely the borrower can make all principal and interest payments as contractually due.

For loans that are collateral dependent, losses are evaluated based on the portion of a loan that exceeds the fair market value of the collateral.  In general, this is the amount that the carrying value of the loan exceeds the related appraised value less estimated costs to sell the collateral.  Generally, it is the Company’s policy not to rely on appraisals that are older than one year prior to the date the impairment is being measured.  The most recent appraisal values may be adjusted if, in the Company’s judgment, experience and other market data indicate that the property’s value, use, condition, exit market or other variable affecting its value may have changed since the appraisal was performed, consistent with the December 2006 joint interagency guidance on the allowance for loan losses.  The charge off or loss adjustment supported by an appraisal is considered the minimum charge off.  Any adjustments made to the appraised value are to provide an additional charge off or specific reserve based on the applicable facts and circumstances.  In instances where there is an estimated decline in value, a specific reserve may be provided or a charge off taken pending confirmation of the amount of the loss from an updated appraisal.  Upon receipt of the new appraisals, an additional specific reserve may be provided or charge off taken based on the appraised value of the collateral.  On average, appraisals are obtained within one month of order.

Fair value of financial instruments:  FASB ASC 820, Fair Value Measurements and Disclosures (“ASC 820”) provides a single definition for fair value, a framework for measuring fair value and expanded disclosures concerning fair value.  Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an 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.

The Company determines the fair market value of its financial instruments based on the fair value hierarchy established in ASC 820.  There are three levels of inputs that may be used to measure fair value as follows:

Level 1 Quoted prices in active markets for identical assets or liabilities.

Level 2 Observable inputs other than quoted prices included within Level 1.  Observable inputs include the quoted prices for similar assets or liabilities in markets that are not active and inputs other than quoted prices that are observable for the asset or liability.

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

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 following is a description of valuation methodologies used for assets and liabilities recorded at fair value and for estimating fair value for assets or liabilities not recorded at fair value.

ASSETS

Cash and cash equivalents:  The carrying amounts reported in the consolidated balance sheets for cash and short-term instruments approximate their fair values (Level 1).

Investment securities available for sale:  Investment securities available for sale are recorded at fair value on a recurring basis.  Fair value measurement is based upon quoted prices, if available.  If a quoted price is not available, the fair value is obtained from benchmarking the security against similar securities.  All of the Company’s securities are considered Level 2.

The pricing for investment securities is obtained from an independent source.  There are no level 1 or level 3 investment securities owned by the Company.  The Company obtains an understanding of the independent source’s valuation methodologies used to determine fair value by level of security. The Company validates assigned fair values on a sample basis using an additional third-party provider pricing service to determine if the fair value measurement is reasonable.  Due to the nature of our investment portfolio, we do not expect significant and unusual fluctuations as fair value changes primarily relate to interest rate changes.   No unusual fluctuations were identified during the nine months ended September 30, 2017.   If a fluctuation requiring investigation was identified, the Company would research the change with the independent source or other available information.

Loans held for sale:  Loans held for sale are carried at historical cost.  The carrying amount is a reasonable estimate of fair value because of the short time between origination of the loan and its sale on the secondary market (Level 2).  The market is active for these loans and as a result prices for similar assets are available.

Page 30

HILLS BANCORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(Unaudited)

Loans:  The Company does not record loans at fair value on a recurring basis.  For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values (Level 3).  The fair values for other loans are determined using estimated future cash flows, discounted at the interest rates currently being offered for loans with similar terms to borrowers with similar credit quality utilizing an entrance price concept (Level 3).  The Company does record nonrecurring fair value adjustments to loans to reflect (1) partial write-downs that are based on the observable market price or appraised value of the collateral or (2) the full charge-off of the loan carrying value (Level 3).  These loans are considered Level 3 as the instruments used to determine fair market value require significant management judgment and estimation.

Foreclosed assets:  The Company does not record foreclosed assets at fair value on a recurring basis.  Foreclosed assets consist mainly of other real estate owned but may include other types of assets repossessed by the Company.  Foreclosed assets are adjusted to the lower of carrying value or fair value less the cost of disposal.   Fair value is generally based upon independent market prices or appraised values of the collateral, and may include a marketability discount as deemed necessary by management based on its experience with similar types of real estate.  The value of foreclosed assets is evaluated periodically as a nonrecurring fair value adjustment.  Foreclosed assets are classified as Level 3.

Off-balance sheet instruments:  Fair values for outstanding letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties' credit standing.  The fair value of the outstanding letters of credit is not significant. Unfunded loan commitments are not valued since the loans are generally priced at market at the time of funding (Level 2).

Accrued interest receivable:  The fair value of accrued interest receivable equals the amount receivable due to the current nature of the amounts receivable (Level 2).

Non-marketable equity investments:  Non-marketable equity investments are recorded under the cost or equity method of accounting.  There are generally restrictions on the sale and/or liquidation of these investments, including stock of the Federal Home Loan Bank.  The carrying value of stock of the Federal Home Loan Bank approximates fair value (Level 2).

LIABILITIES

Deposit liabilities:  Deposit liabilities are carried at historical cost.  The fair value of demand deposits, savings accounts and certain money market account deposits is the amount payable on demand at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities.  If the fair value of the fixed maturity certificates of deposit is calculated at less than the carrying amount, the carrying value of these deposits is reported as the fair value (Level 2).  Deposit liabilities are classified as Level 2 due to available prices for similar liabilities in the market.

Other borrowings:  Other borrowings are carried at historical cost and include federal funds purchased and securities sold under agreements to repurchase.  The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the liability and its expected realization (Level 2). Other borrowings are classified as Level 2 due to available prices for similar liabilities in the market.

Federal Home Loan Bank borrowings:  Federal Home Loan Bank borrowings are recorded at historical cost.  The fair values of the Company’s Federal Home Loan Bank borrowings are estimated using discounted cash flow analysis, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements (Level 2).  Federal Home Loan Bank borrowings are classified as Level 2 due to available prices for similar liabilities in the market.

Interest Rate Swap Agreements: The fair value is estimated using forward-looking interest rate curves and is calculated using discounted cash flows that are observable or that can be corroborated by observable market data (Level 2).

Accrued interest payable:  The fair value of accrued interest payable equals the amount payable due to the current nature of the amounts payable (Level 2).

Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis

The Company is required to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP.  These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets.  The valuation methodologies used to measure these fair value adjustments are described above.    The following tables present the Company’s assets that are measured at fair value on a nonrecurring basis.

Note 7. Stock Repurchase Program

On July 26, 2005, the Company’s Board of Directors authorized a program to repurchase up to a total of 1,500,000 shares of the Company’s common stock (the “2005 Stock Repurchase Program”).  The Company’s Board of Directors has authorized the 2005 Stock Repurchase Program through December 31, 2018.  The Company expects the purchases pursuant to the 2005 Stock Repurchase Program to be made from time to time in private transactions at a price equal to the most recent quarterly independent appraisal of the shares of the Company’s common stock and with the Board reviewing the overall results of the 2005 Stock Repurchase Program on a quarterly basis.  All purchases made pursuant to the 2005 Stock Repurchase Program since its inception have been made on that basis.  The amount and timing of stock repurchases will be based on various factors, such as the Board’s assessment of the Company’s capital structure and liquidity, the amount of interest shown by shareholders in selling shares of stock to the Company at their appraised value, and applicable regulatory, legal and accounting factors.  The Company has purchased 1,003,216 shares of its common stock in privately negotiated transactions from August 1, 2005 through September 30, 2017.  Of these 1,003,216 shares, 14,538 shares were purchased during the quarter ended September 30, 2017, at an average price per share of $52.80.

Note 8. Commitments and Contingencies

Concentrations of credit risk:  The Bank’s loans, commitments to extend credit, unused lines of credit and outstanding letters of credit have been granted to customers within the Bank's market area.  Investments in securities issued by state and political subdivisions within the state of Iowa totaled approximately $68.95 million.  The concentrations of credit by type of loan are set forth in Note 5 to the Consolidated Financial Statements.  Outstanding letters of credit were granted primarily to commercial borrowers.  Although the Bank has a diversified loan portfolio, a substantial portion of its debtors' ability to honor their contracts is dependent upon the economic conditions in Johnson, Linn and Washington Counties, Iowa.

Contingencies:  In the normal course of business, the Company and Bank are involved in various legal proceedings.  While the ultimate outcome of such legal proceedings cannot be predicted with certainty, after reviewing pending and threatened litigation with counsel, management believes at this time that the outcome of such litigation will not have a material adverse effect on the Company's business, financial condition or results of operations.

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, credit card participations and standby letters of credit.  These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets.

The Bank’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, credit card participations and standby letters of credit is represented by the contractual amount of those instruments.  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 September 30, 2017 and December 31, 2016 is as follows:

	September 30, 2017		December 31, 2016
	(Amounts In Thousands)
Firm loan commitments and unused portion of lines of credit:
Home equity loans	$	54,200	$	48,785
Credit cards	49,107		45,738
Commercial, real estate and home construction	138,982		113,251
Commercial lines and real estate purchase loans	171,516		180,892
Outstanding letters of credit	11,398		9,024

Note 9. Income Taxes

Federal income tax expense for the nine months ended September 30, 2017 and 2016 was computed using the consolidated effective federal tax rate.  The Company also recognized income tax expense pertaining to state franchise taxes payable individually by the subsidiary bank.  The Company files a consolidated tax return for federal purposes and separate tax returns for State of Iowa purposes.  The tax years ended December 31, 2016, 2015, and 2014 remain subject to examination by the Internal Revenue Service.  For state tax purposes, the tax years ended December 31, 2016, 2015, and 2014 remain open for examination.  There were no material unrecognized tax benefits at September 30, 2017  and December 31, 2016 and therefore no interest or penalties on unrecognized tax benefits has been recorded.  As of September 30, 2017, the Company does not anticipate any significant increase in unrecognized tax benefits during the twelve-month period ending September 30, 2018. Income taxes as a percentage of income before taxes were 30.48% for the nine months ended September 30, 2017 and 31.40% for the same period in 2016.

Note 10. Derivative Financial Instruments

In the normal course of business, the Bank may use derivative financial instruments to manage its interest rate risk.  These instruments carry varying degrees of credit, interest rate and market or liquidity risks.  Derivative instruments are recognized as either assets or liabilities in the accompanying financial statement and are measured at fair value.  The Bank’s objectives are to add stability to its net interest margin and to manage its exposure to movements in interest rates.  The contract or notional amount of a derivative is used to determine, along with the other terms of the derivative, the amount to be exchanged between the counterparties.  The Bank is exposed to credit risk in the event of nonperformance by counterparties to financial instruments.  The Bank minimizes this risk by entering into derivative contracts with large, stable financial institutions.  The Bank has not experienced any losses from nonperformance by counterparties.  The Bank monitors counterparty risk in accordance with the provisions of ASC 815.  In addition, the Bank’s interest rate-related derivative instruments contain language outlining collateral pledging requirements for each counterparty.  Collateral must be posted when the market value exceeds certain threshold limits which are determined by credit ratings of each counterparty.  The Bank was required to pledge $3.46 million of collateral as of September 30, 2017.

Cash Flow Hedges:

The Bank executed two forward-starting interest rate swap transactions on November 7, 2013.  One of the interest rate swap transactions had an effective date of November 9, 2015, and an expiration date of November 9, 2020, effectively converting $25.00 million of variable rate debt to fixed rate debt.  The other interest rate swap transaction had an effective date of November 7, 2016 and an expiration date of November 7, 2023, effectively converting $25.00 million of variable rate debt to fixed rate debt.  For accounting purposes, these swap transactions are designated as a cash flow hedge of the changes in cash flows attributable to changes in three-month LIBOR, the benchmark interest rate being hedged, associated with the interest payments made on an amount of the Bank’s debt principal equal to the then-outstanding swap notional amount.  At inception, the Bank asserted that the underlying principal balance would remain outstanding throughout the hedge transaction making it probable that sufficient LIBOR-based interest payments would exist through the maturity date of the swaps.

The table below identifies the balance sheet category and fair values of the Bank’s derivative instruments designated as cash flow hedges as of September 30, 2017 and December 31, 2016:

	Notional Amount		Fair Value			Balance Sheet Category	Maturity

• The strength of the United States economy in general and the strength of the local economies in which the Company conducts its operations which may be less favorable than expected and may result in, among other things, a deterioration in the credit quality and value of the Company’s assets.

• The effects of recent financial market disruptions, and monetary and other governmental actions designed to address such disruptions.

• The financial strength of the counterparties with which the Company or the Company’s customers do business and as to which the Company has investment or financial exposure.

Page 37

HILLS BANCORPORATION

• The credit quality and credit agency ratings of the securities in the Company’s investment securities portfolio, a deterioration or downgrade of which could lead to other-than-temporary impairment of the affected securities and the recognition of an impairment loss.

• The effects of, and changes in, laws, regulations and policies affecting banking, securities, insurance and monetary and financial matters as well as any laws otherwise affecting the Company.

• The effects of changes in interest rates (including the effects of changes in the rate of prepayments of the Company’s assets) and the policies of the Board of Governors of the Federal Reserve System.

• The ability of the Company to compete with other financial institutions as effectively as the Company currently intends due to increases in competitive pressures in the financial services sector.

• The ability of the Company to obtain new customers and to retain existing customers.

• The timely development and acceptance of products and services, including products and services offered through alternative electronic delivery channels.

Critical Accounting Policies

The Company's consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The financial information contained within these financial statements is, to a significant extent, financial information that is based on approximate measures of the financial effects of transactions and events that have already occurred. Based on its consideration of accounting policies that involve the most complex and subjective decisions and assessments, management has identified its most critical accounting policies to be those which are related to the allowance for loan losses. The Company's allowance for loan losses methodology incorporates a variety of risk considerations, both quantitative and qualitative in establishing an allowance for loan losses that management believes is appropriate at each reporting date. Quantitative factors include the Company's historical loss experience, delinquency and charge-off trends, collateral values, changes in impaired loans, and other factors. Quantitative factors also incorporate known information about individual loans, including borrowers' sensitivity to interest rate movements. Qualitative factors include the general economic environment in the Company's markets, including

economic conditions throughout the Midwest and the state of certain industries.  Determinations relating to the possible level of future loan losses are based in part on subjective judgments by management.  Future loan losses in excess of current estimates, could materially adversely affect our results of operations or financial position.  Size and complexity of individual credits in relation to loan structure, existing loan policies and pace of portfolio growth are other qualitative factors that are considered in the methodology. As the Company adds new products and increases the complexity of its loan portfolio, it will enhance its methodology accordingly. This discussion of the Company’s critical accounting policies should be read in conjunction with the Company’s consolidated financial statements and the accompanying notes presented elsewhere herein, as well as other relevant portions of Management’s Discussion and Analysis of Financial Condition and Results of Operations.  Although management believes the levels of the allowance as of September 30, 2017 and December 31, 2016 were adequate to absorb probable losses inherent in the loan portfolio, a decline in local economic conditions, or other factors, could result in increasing losses that cannot be reasonably predicted at this time.

Overview

This overview highlights selected information and may not contain all of the information that is important to you in understanding our performance during the period.  For a more complete understanding of trends, events, commitments, uncertainties, liquidity, capital resources, and critical accounting estimates, you should carefully read this entire report.

The Company is a holding company engaged in the business of commercial banking.  The Company’s subsidiary is Hills Bank and Trust Company, Hills, Iowa (the “Bank”), which is wholly-owned.  The Bank was formed in Hills, Iowa in 1904.  The Bank is a full-service commercial bank extending its services to individuals, businesses, governmental units and institutional customers primarily in the communities of Hills, Iowa City, Coralville, North Liberty, Lisbon, Mount Vernon, Kalona, Wellman, Cedar Rapids, Marion, and Washington, Iowa.  At September 30, 2017, the Bank has nineteen full-service locations.

Net income for the nine month period ended September 30, 2017 was $23.88 million compared to $24.84 million for the same nine months of 2016, a decrease of 3.86%.  The $0.96 million decrease in net income was caused by a number of factors.  The principal factors in the decrease in net income for the first nine months of 2017 are an increase in noninterest expenses of $3.09 million and an increase in provision for loan losses of $3.83 million. These changes were offset by an increase in net interest income of $4.87 million, an increase in noninterest income of $0.19 million, and a decrease in income tax expense of $0.90 million.

The Company achieved a return on average assets of 1.14% and a return on average equity of 10.39% for the twelve months ended September 30, 2017, compared to the twelve months ended September 30, 2016, which were 1.23% and 11.59%, respectively.  Dividends of $0.70 per share were paid in January 2017 to 2,390 shareholders.  The 2016 dividend was $0.65 per share.

The Company’s net interest income is the largest component of revenue and it is primarily a function of the average earning assets and the net interest margin percentage.  The Company achieved a net interest margin on a tax-equivalent basis of 3.46% for the nine months ended September 30, 2017 compared to 3.42% for the same nine months of 2016.  Average earning assets were $2.611 billion year to date in 2017 and $2.435 billion in 2016.

The Bank has an established formal loan origination policy.  In general, the loan origination policy attempts to reduce the risk of credit loss to the Bank by requiring, among other things, maintenance of minimum loan to value ratios, evidence of appropriate levels of insurance carried by borrowers and documentation of appropriate types and amounts of collateral and sources of expected payment.  The collateral relied upon in the loan origination policy is generally the property being financed by the Bank.  The source of expected payment is generally the income produced from the property being financed.  Personal guarantees are required of individuals owning or controlling at least 20% of the ownership of an entity.  Limited or proportional guarantees may be accepted in circumstances if approved by the Company’s Board of Directors.  Financial information provided by the borrower is verified as considered necessary by reference to tax returns, or audited, reviewed or compiled financial statements.  The Bank does not originate subprime loans.  In order to modify, restructure or otherwise change the terms of a loan, the Bank’s policy is to evaluate each borrower situation individually.  Modifications, restructures, extensions and other changes are done to improve the Bank’s position and to protect the Bank’s capital.  If a borrower is not current with its payments, any additional loans to such borrowers are evaluated on an individual borrower basis.

The Company has not experienced any significant time lapses in recognizing the required provisions for collateral dependent loans, nor has the Company delayed appropriate charge offs.  When an updated appraisal value has been obtained, the Company has used the appraisal amount in determining the appropriate charge off or required reserve.  The Company also evaluates any changes in the financial condition of the borrower and guarantors (if applicable), economic conditions, and the Company’s loss experience with the type of property in question.  Any information utilized in addition to the appraisal is intended to identify additional charge offs or provisions, not to override the appraised value.

In accordance with Staff Accounting Bulletin No. 102, Selected Loan Loss Allowance Methodology and Documentation Issues, the Company determines and assigns ratings to loans using factors that include the following: an assessment of the financial condition of the borrower; a realistic determination of the value and adequacy of underlying collateral; the condition of the local economy and the condition of the specific industry of the borrower; an analysis of the levels and trends of loan categories; and a review of delinquent and classified loans.

Through the credit risk rating process, loans are reviewed to determine if they are performing in accordance with the original contractual terms. If the borrower has failed to comply with the original contractual terms, further action may be required by the Company, including a downgrade in the credit risk rating, movement to non-accrual status, a charge-off or the establishment of a specific impairment reserve. In the event a collateral shortfall is identified during the credit review process, the Company will work with the borrower for a principal reduction and/or a pledge of additional collateral and/or additional guarantees. In the event that these options are not available, the loan may be subject to a downgrade of the credit risk rating. If the Company determines a loan amount or portion thereof, is uncollectible, the loan’s credit risk rating may be downgraded and the uncollectible amount charged-off or recorded as a specific allowance for losses.  The Bank’s credit and legal departments undertake a thorough and ongoing analysis to determine if additional impairment and/or charge-offs are appropriate and to begin a workout plan for the loan to minimize actual losses.

	$	29,350	100.00	%	100.00	%	$	26,530	100.00	%	100.00	%

The allowance for loan losses totaled $29.35 million at September 30, 2017 compared to $26.53 million at December 31, 2016.  The percentage of the allowance to outstanding loans was 1.21% and 1.17% at September 30, 2017 and December 31, 2016, respectively.  The allowance was based on management’s consideration of a number of factors, including composition of the loan portfolio, loans with higher credit risks and the overall amount of loans outstanding.  The increase in the allowance in 2017 is the result of $136.90 million million in loan growth and a change in the composition and allocation of loans within credit quality ratings.

The adequacy of the allowance is reviewed quarterly and adjusted as appropriate after consideration has been given to the impact of economic conditions on the borrowers’ ability to repay, loan collateral values, past collection experience, the risk characteristics of the loan portfolio and such other factors that deserve current recognition. The growth of the loan portfolio and the trends in problem and watch loans are significant elements in the determination of the provision for loan losses.  Quantitative factors include the Company’s historical loss experience, which is then adjusted for levels and trends in past due, levels and trends in charged-off and recovered loans, trends in volume growth, trends in problem and watch loans, trends in restructured loans, local economic trends and conditions, industry and other conditions, and effects of changing interest rates.

Management has determined that the allowance for loan losses was appropriate at September 30, 2017, and that the loan portfolio is diversified and secured, without undue concentration in any specific risk area. This process involves a high degree of management judgment; however, the allowance for loan losses is based on a comprehensive, well documented, and consistently applied analysis of the Company’s loan portfolio. This analysis takes into consideration all available information existing as of the financial statement date, including environmental factors such as economic, industry, geographical and political factors. The relative level of allowance for loan losses is reviewed and compared to industry data. This review encompasses levels of total impaired loans, portfolio mix, portfolio concentrations, current geographic risks and overall levels of net charge-offs.

Residential real estate loan products that include features such as loan-to-values in excess of 100% or interest only payments, which expose a borrower to payment increases in excess of changes in the market interest rate, increase the credit risk of a loan.  The Bank has not offered and does not intend to offer this type of loan product.

Investment securities available for sale held by the Company decreased by $12.55 million from December 31, 2016 to September 30, 2017.  The fair value of securities available for sale was $1.30 million more than the amortized cost of such securities as of September 30, 2017.  At December 31, 2016, the fair value of the securities available for sale was $1.50 million less than the amortized cost of such securities.

Deposits increased $36.73 million in the first nine months of 2017. Repurchase agreements decreased $19.73 million since December 31, 2016.  In the opinion of the Company’s management, the Company continues to have sufficient liquidity resources available to fund expected additional loan growth.

Brokered deposits are included in total deposits and totaled $73.09 million as of September 30, 2017 with an average rate of 0.99%.  Brokered deposits were $112.70 million as of December 31, 2016 with an average interest rate of 0.59%. As of September 30, 2017 and December 31, 2016, brokered deposits were 3.53% and 5.53% of total deposits, respectively.

FHLB Borrowings increased $88.00 million to $323.00 million for the nine months ended September 30, 2017. This increase was primarily used to fund the $136.90 million of loan growth for the nine months ended September 30, 2017.

Dividends and Equity

In January 2017, Hills Bancorporation paid a dividend of $6.49 million or $0.70 per share.  The dividend was $0.65 per share in January 2016.  After payment of the dividend and the adjustment for accumulated other comprehensive income, stockholders’ equity as of September 30, 2017 totaled $309.57 million. On January 1, 2015, the final rules of the Federal Reserve Board went into effect implementing in the United States the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision. The final rule also adopted changes to the agencies’ regulatory capital requirements that meet the requirements of section 171 and section 939A of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

Under the BASEL III rules, the minimum capital ratios are 4% for Tier 1 Leverage Capital Ratio, 4.5% for the Common Equity Tier 1 Capital Ratio, 6% for the Tier 1 Risk-Based Capital Ratio and 8% for the Total Risk-Based Capital Ratio. A new capital conservation buffer is being phased in beginning January 1, 2016, at 0.625% of risk-weighted assets and increased each subsequent year by an additional 0.625% until reaching 2.5% on January 1, 2019. As of September 30, 2017 and December 31, 2016 the Company had regulatory capital in excess of the Federal Reserve’s minimum and well-capitalized definition requirements.

Net Income Overview

Net income decreased $0.96 million for the nine months ended September 30, 2017 compared to the first nine months of 2016.  Total net income was $23.88 million in 2017 and $24.84 million in the comparable period in 2016, an decrease of 3.86%.  The changes in net income in 2017 from the first nine months of 2016 were primarily the result of the following:

• Net interest income increased by $4.87 million, before provision expense. Total interest income increased by $5.70 million as a result of growth in the volume of earning assets.

• The provision for loan losses increased by $3.83 million.

• Noninterest income increased by $0.19 million.

• Noninterest expenses increased by $3.09 million.

• Income tax expense decreased by $0.90 million.

For the nine month period ended September 30, 2017 and September 30, 2016 basic earnings per share was $2.56 and $2.67, respectively. Diluted earnings per share was $2.56 for the nine months ended September 30, 2017 compared to $2.67 for the same period in 2016.

The Company’s net income continues to be driven primarily by three important factors.  The first important factor is the interaction between changes in net interest margin and changes in average volumes of the Bank's earnings assets.  Net interest income of $65.37 million for the first nine months of 2017 was derived from the Company’s $2.611 billion of average earning assets during that period and its tax-equivalent net interest margin of 3.46%.  Average earning assets in the nine months ended September 30, 2016 were $2.435 billion and the tax-equivalent net interest margin was 3.42%.  Net interest margin is the yield generated from earning assets minus interest expense represented as a percentage of the Bank's earning assets. The importance of net interest margin is illustrated by the fact that an increase or decrease in the net interest margin of 10 basis points would have resulted approximately in a $1.96 million change in income before income taxes in the nine month period ended September 30, 2017.  Net interest income for the Company increased primarily as a result of growth in the volume of earning assets.  The Company expects net interest income to remain stable through 2017 and net interest compression to impact earnings in future years.  The Company believes growth in net interest income will be contingent on the growth of the Company’s earnings assets.

The second significant factor affecting the Company’s net income is the provision for loan losses. The majority of the Company’s interest-earning assets are in loans outstanding, which amounted to more than $2.398 billion at September 30, 2017.  The provision is computed on a quarterly basis and is a result of management’s determination of the quality of the loan portfolio.  The provision reflects a number of factors, including the size of the loan portfolio, the overall composition of the loan portfolio and loan concentrations, the borrowers’ ability to repay, past loss experience, loan collateral values, the level of impaired loans and loans past due ninety days or more.  In addition, management considers the credit quality of the loans based on management’s review of problem and watch loans, including loans with historically higher credit risk.  The provision for loan losses was an expense of $1.83 million in 2017 compared to a reduction of expense of $2.00 million in 2016.  The majority of the increase was the result of $14.09 million in loans in which a specific reserve of $1.47 million was allocated. The Company believes that the provision for loan losses may increase for the foreseeable future resulting from projected increases in the size of the Company’s loan portfolio.

The third significant factor affecting the Company’s net income is income tax expense.  Federal and state income tax expenses were $10.47 million and $11.37 million for the nine months ended September 30, 2017 and 2016, respectively.  Income taxes as a percentage of income before taxes were 30.48% in 2017 and 31.40% in 2016.

Net Interest Income

Net interest income increased for the nine months ended September 30, 2017 compared to the comparable period in 2016.  The increase was as a result of growth in the average volume of earning assets.  Net interest income is the excess of the interest and fees earned on interest-earning bearing assets over the interest expense of the interest-bearing liabilities.  The factors that have the greatest impact on net interest income are the average volume of earning assets for the period and the net interest margin.  The net interest margin for the first nine months of 2017 was 3.46% compared to 3.42% in 2016 for the same period.  The measure is shown on a tax-equivalent basis using a tax rate of 35% to make the interest earned on taxable and non-taxable assets more comparable.  The change in average balances and average rates between periods and the effect on the net interest income on a tax equivalent basis for the nine months ended in 2017 compared to the comparable period in 2016 are shown in the following table:

						Increase (Decrease) in Net Interest Income

Rate/volume variances are allocated on a consistent basis using the absolute values of changes in volume compared to the absolute values of the changes in rates.  Loan fees included in interest income are not material.  Interest on nontaxable securities and loans is shown on a tax-equivalent basis.

A summary of the net interest spread and margin is as follows:

(Tax Equivalent Basis)	2017		2016
Yield on average interest-earning assets	4.11	%	4.08	%
Rate on average interest-bearing liabilities	0.85		0.84
Net interest spread	3.26	%	3.24	%
Effect of noninterest-bearing funds	0.20		0.18
Net interest margin (tax equivalent interest income divided by average interest-earning assets)	3.46	%	3.42	%

In pricing loans and deposits, the Bank considers the U.S. Treasury indexes as benchmarks in determining interest rates.  The Federal Open Market Committee met six times during the first nine months of 2017.  The target rate was increased in June, 2017 at 1.25%.  Interest rates on loans are generally affected by the target rate since interest rates for the U.S. Treasury market normally increase or decrease when the Federal Reserve Board raises or lowers the federal funds rate.  As of September 30, 2017, the rate indexes for the one, three and five year indexes were 1.31%, 1.62% and 1.92%, respectively.  The one year index increased 122.03% from 0.59% at September 30, 2016, the three year index increased 84.10% and the five year index increased 68.42%.  The three year index was 0.88% and the five year index was 1.14% at September 30, 2016.  The targeted federal funds rate was 1.25% and 0.50% at September 30, 2017 and 2016, respectively.  The Company anticipates possible increases in short term and long term rates in the indexes for the remainder of 2017.

Provision for Loan Losses

The provision for loan losses was an expense of $1.83 million for the nine months ended September 30, 2017 compared to a reduction of expense of $2.00 million in 2016, an expense increase of $3.83 million.  The loan loss provision is the amount necessary to adjust the allowance for loan losses to the level considered by management to appropriately account for the estimated impairment to the Bank's loan portfolio.  The provision expense taken to fund the allowance for loan losses is computed on a quarterly basis and is a result of management’s determination of the quality of the loan portfolio.  The provision reflects a number of factors, including the size of the loan portfolio, the overall composition of the loan portfolio and loan concentrations, the impact on the borrowers’ ability to repay, past loss experience, loan collateral values, the level of impaired loans and loans past due ninety days or more.  In addition, management considers the credit quality of the loans based on management’s review of problem and watch loans, including loans with historical higher credit risks.  The increase in expense in 2017 is the net result of an increase in net loans, a change in the composition and allocation of loans within credit quality ratings, and a specific allowance of $1.47 million recorded for $14.09 million in 2 loan relationships.

The allowance for loan losses increased $2.82 million during the first nine months of 2017.  In the first nine months of 2017, there was a increase of $2.93 million due to increases in average balances and composition of loans outstanding and a $0.11 million decrease in the amount allocated to the allowance due to declines in credit quality.

The allowance for loan losses balance is affected by charge-offs, net of recoveries, for the periods presented.  For the nine months ended September 30, 2017 and 2016, recoveries were $2.46 million and $3.15 million respectively; and charge-offs were $1.46 million in 2017 and $1.52 million in 2016.  The allowance for loan losses totaled $29.35 million at September 30, 2017 compared to $26.53 million at December 31, 2016.  The allowance represented 1.21% and 1.17% of loans held for investment at September 30, 2017 and December 31, 2016.

Discussion of operations for the nine months ended September 30, 2017 and 2016

Loans originated for sale in the first ninemonths of 2017 totaled $109.52 million compared to $151.55 million in the same period in 2016, a decrease of 27.73%.  In the nine months ended September 30, 2017 and 2016, the net gain on sale of loans was $1.12 million and $1.44 million, respectively.  The amount of the net gain on sale of secondary market mortgage loans in each year can vary significantly.  The volume of activity in these types of loans is directly related to the level of interest rates.  The servicing of the loans sold into the secondary market is not retained by the Company so these loans do not provide an ongoing stream of income.  The Company believes residential mortgage interest rates will continue to rise for the foreseeable future resulting in decreased net gain on sale of loan income.

Trust fees increased $0.70 million in the nine months ended September 30, 2017 compared to September 30, 2016 due to new trust relationships.

Net gain on sale of other real estate owned and other repossessed assets decreased $0.28 million in the nine months ended September 30, 2017 compared to September 30, 2016 due to a decrease in the amount of other real estate owned by the Company.

Noninterest Expenses

The following table sets forth the various categories of noninterest expenses for the nine months ended September 30, 2017 and 2016.

	Nine Months Ended September 30,
	2017		2016		$ Change			% Change
	(Amounts in thousands)

Office supplies and postage	1,487		1,282		205			15.99
Advertising and business development	2,123		2,426		(303		)	(12.49	)
Outside services	5,943		5,386		557			10.34

	$	44,433	$	41,346	$	3,087		7.47

In the nine months ended September 30, 2017 and 2016, salaries and employee benefits expense increased $2.09 million. The increase is primarily the result of annual salary adjustments and hiring of additional employees to staff branch growth. Other noninterest expense categories experienced marginal period-to-period fluctuations for the nine months ended September 30, 2017.

Net Income Overview

Net income decreased $0.62 million for the three months ended September 30, 2017 compared to the same period in 2016.  Total net income was $8.55 million in 2017 and $9.18 million in the comparable period in 2016, a decrease of 6.80%.  For the three month period ended September 30, 2017 and September 30, 2016 basic earning per share was $0.92 and $0.99, respectively. Diluted earnings per share was $0.92 for the three months ended September 30, 2017 compared to $0.99 for the same period in 2016.

Net Interest Income

Net interest income increased for the three months ended September 30, 2017 compared to the comparable period in 2016.  The increase was primarily the result of growth in the volume of earning assets.  Net interest income is the excess of the interest and fees earned on interest-earning bearing assets over the interest expense of the interest-bearing liabilities.  The factors that have the greatest impact on net interest income are the volume of average earning assets and the net interest margin.  The net interest margin for the three months ended September 30, 2017 was 3.44% compared to 3.49% in 2016 for the same period.  The measure is shown on a tax-equivalent basis using a tax rate of 35% to make the interest earned on taxable and non-taxable assets more comparable.  The change in average balances and average rates between periods and the effect on the net interest income on a tax equivalent basis for the three months ended in 2017 compared to the comparable period in 2016 are shown in the following table:

						Increase (Decrease) in Net Interest Income

Provision for Loan Losses

The provision for loan losses was an expense of $0.13 million for the three months ended September 30, 2017 compared to a reduction of expense of $1.83 million in 2016, an expense increase of $1.96 million. The loan loss provision is the amount necessary to adjust the allowance for loan losses to the level considered by management to appropriately account for the estimated impairment to the Bank's loan portfolio.  The provision expense taken to fund the allowance for loan losses is computed on a quarterly basis and is a result of management’s determination of the quality of the loan portfolio.  The provision reflects a number of factors, including the size of the loan portfolio, the overall composition of the loan portfolio and loan concentrations, the impact on the borrowers’ ability to repay, past loss experience, loan collateral values, the level of impaired loans and loans past due ninety days or more.  In addition, management considers the credit quality of the loans based on management’s review of problem and watch loans, including loans with historical higher credit risks. 

The allowance for loan losses increased $0.40 million during the three months ended September 30, 2017.  In the three months ended September 30, 2017, there was a $0.32 million decrease in the amount allocated to the allowance due to credit quality and a $0.72 million increase due to the composition of loans outstanding.

In addition to provision expense, the allowance for loan losses balance is affected by charge-offs, net of recoveries, for the periods presented.  For the three months ended September 30, 2017 and 2016, recoveries were $0.58 million and $1.16 million, respectively; and charge-offs were $0.31 million in 2017 and $0.48 million in 2016.

Other noninterest income	372		396		(24		)	(6.06	)
	$	5,005	$	5,314	$	(309	)	(5.81	)

In the three months ended September 30, 2017 and 2016, the net gain on sale of loans was $0.42 million and $0.60 million , respectively.  The amount of the net gain on sale of secondary market mortgage loans in each year can vary significantly.  The volume of activity in these types of loans is directly related to the level of interest rates.  The servicing of the loans sold into the secondary market is not retained by the Company so these loans do not provide an ongoing stream of income.  The Company believes residential mortgage interest rates will continue to rise for the foreseeable future resulting in decreased net gain on sale of loan income.

Trust fees increased $0.25 million in the three months ended September 30, 2017 compared to September 30, 2016 due to new trust relationships.

Net gain on sale of other real estate owned and other repossessed assets decreased $0.31 million in the three months ended September 30, 2017 compared to September 30, 2016 due to a decrease in the amount of other real estate owned by the Company.

Income Taxes

Federal and state income tax expenses were $3.72 million and $4.40 million for the three months ended September 30, 2017 and 2016, respectively.  Income taxes as a percentage of income before taxes were 30.32% in 2017 and 32.40% in 2016.

Liquidity

The Company actively monitors and manages its liquidity position with the objective of maintaining sufficient cash flows to fund operations, meet client commitments, take advantage of market opportunities and provide a margin against unforeseeable liquidity needs.  Federal funds sold and investment securities available for sale are readily marketable assets.  Maturities of all investment securities are managed to meet the Company’s normal liquidity needs, to respond to market changes or to adjust the Company’s interest rate risk position.  Investment securities available for sale comprised 9.16% of the Company’s total assets at September 30, 2017 compared to 10.07% at December 31, 2016.

The Company has historically maintained a stable deposit base and a relatively low level of large deposits, which has mitigated the volatility in the Company’s liquidity position.  As of September 30, 2017, the Company had borrowed $323.00 million from the Federal Home Loan Bank (“FHLB”) of Des Moines.  Advances are used as a means of providing both long and short-term, fixed-rate funding for certain assets and for managing interest rate risk.  The Company had additional borrowing capacity available from the FHLB of approximately $457.59 million at September 30, 2017.

As additional sources of liquidity, the Company has the ability to borrow up to $10.00 million from the Federal Reserve Bank of Chicago, and has lines of credit with three banks totaling $244.70 million.  The borrowings under these credit lines would be secured by the Bank’s investment securities.  The combination of high levels of potentially liquid assets, low dependence on volatile liabilities and additional borrowing capacity provided sources of liquidity for the Company which management considered sufficient at September 30, 2017.

As of September 30, 2017, investment securities with a carrying value of $30.46 million were pledged to collateralize public and trust deposits, repurchase agreements, derivative financial instruments, and other borrowings.  As of December 31, 2016, investment securities with a carrying value of $61.81 million were pledged.

Contractual Obligations

There have been no material changes with regard to contractual obligations disclosed in the Company’s Form 10-K for the year ended December 31, 2016.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

The Company's primary market risk exposure is to changes in interest rates.  Interest rate risk is the risk to current or anticipated earnings or capital arising from movements in interest rates.  Interest rate risk arises from repricing risk, basis risk, yield curve risk and options risk.  Repricing risk is the difference between the timing of rate changes and the timing of cash flows.  Basis risk is the difference from changing rate relationships among different yield curve affecting Bank activities.  Yield curve risk is the difference from changing rate relationships across the spectrum of maturities.  Option risk is the difference resulting from interest-related options imbedded in Bank products.  The Bank’s primary source of interest rate risk exposure arises from repricing risk.  To measure this risk the Bank uses a static gap measurement system that identifies the repricing gaps across the full maturity spectrum of the Bank’s assets and liabilities and an earnings simulation approach.  The gap schedule is known as the interest rate sensitivity report.  The report reflects the repricing characteristics of the Bank’s assets and liabilities.  The report details the calculation of the gap ratio.  This ratio indicates the amount of interest-earning assets repricing within a given period in comparison to the amount of interest-bearing liabilities repricing within the same period of time.  A gap ratio of 1.0 indicates a matched position, in which case the effect on net interest income due to interest rate movements will be minimal.  A gap ratio of less than 1.0 indicates that more liabilities than assets reprice within the time period, and a ratio greater than 1.0 indicates that more assets reprice than liabilities.

The Company's asset/liability management, or its management of interest rate risk, is focused primarily on evaluating and managing net interest income given various risk criteria.  Factors beyond the Company's control, such as market interest rates and competition, may also have an impact on the Company's interest income and interest expense.  In the absence of other factors, the Company's overall yield on interest-earning assets will increase as will its cost of funds on its interest-bearing liabilities when market interest rates increase over an extended period of time.  Inversely, the Company's yields and cost of funds will decrease when market rates decline.  The Company is able to manage these swings to some extent by attempting to control the maturity or rate adjustments of its interest-earning assets and interest-bearing liabilities over given periods of time.

The Bank maintains an Asset/Liability Committee, which meets at least quarterly to review the interest rate sensitivity position and to review and develop various strategies for managing interest rate risk within the context of the following factors: 1) capital adequacy, 2) asset/liability mix, 3) economic outlook, 4) market characteristics and 5) the interest rate forecast.  In addition, the Bank uses a simulation model to review various assumptions relating to interest rate movement.  The model attempts to limit rate risk even if it appears the Bank’s asset and liability maturities are perfectly matched and a favorable interest margin is present.  The Bank’s policy is to generally maintain a balance between profitability and interest rate risk.

In order to minimize the potential effects of adverse material and prolonged increases or decreases in market interest rates on the Company's operations, management has implemented an asset/liability program designed to mitigate the Company's interest rate sensitivity.  The program emphasizes the origination of adjustable rate loans, which are held in the portfolio, the investment of excess cash in short or intermediate term interest-earning assets, and the solicitation of transaction deposit accounts, which are less sensitive to changes in interest rates and can be re-priced rapidly.

The Bank's interest rate risk, as monitored by management, has not changed materially from December 31, 2016.

Item 4. Controls and Procedures

The Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).  Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective, as of the end of the period covered by this report, in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Company in the reports it files with the Securities and Exchange Commission.  There have been no changes in the Company’s internal controls over financial reporting during the quarter ended September 30, 2017 that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting.

Total	14,538	$	52.80	14,538	496,784

(1)  On July 26, 2005, the Company’s Board of Directors authorized a program to repurchase up to 1,500,000 shares of the Company’s common stock (the “2005 Stock Repurchase Program”).  The Company’s Board of Directors has authorized the 2005 Stock Repurchase Program through December 31, 2018.  The Company expects the purchases pursuant to the 2005 Stock Repurchase Program to be made from time to time in private transactions at a price equal to the most recent quarterly independent appraisal of the shares of the Company’s common stock and with the Board reviewing the overall results of the 2005 Stock Repurchase Program on a quarterly basis.  All purchases made pursuant to the 2005 Stock Repurchase Program since its inception have been made on that basis.  The amount and timing of stock repurchases will be based on various factors, such as the Board’s assessment of the Company’s capital structure and liquidity, the amount of interest shown by shareholders in selling shares of stock to the Company at their appraised value, and applicable regulatory, legal and accounting factors.

Summary of Significant Accounting Policies

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation:

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and with instructions for Form 10-Q and Regulation S-X.  These financial statements include all adjustments (consisting of normal recurring accruals) which in the opinion of management are considered necessary for the fair presentation of the financial position and results of operations for the periods shown.  Certain prior year amounts have been reclassified to conform to the current year presentation.  The Company considers that it operates as one business segment, a commercial bank.

Operating results for the nine month period ended September 30, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2017.  For further information, refer to the consolidated financial statements and footnotes thereto included in the Form 10-K Annual Report of Hills Bancorporation and subsidiary (the “Company”) for the year ended December 31, 2016 filed with the Securities Exchange Commission on March 3, 2017.  The consolidated balance sheet as of December 31, 2016, has been derived from the audited consolidated financial statements for that period.

The Company evaluated subsequent events through the filing date of its quarterly report on Form 10-Q with the SEC.

Effect of New Financial Accounting Standards:

In May 2014, The FASB and International Accounting Standards Board (IASB) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of ASU 2014-09 is that a company should recognize revenue to depict the transfer of promised good or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. For financial institutions, significant changes are not expected given that most financial instruments are not in the scope of the accounting standard update. ASU 2014-09 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. In August 2015, FASB issued ASU 2015-14 deferring the effective date for annual periods and interim periods within those annual periods after December 15, 2017. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company has evaluated all of its noninterest income streams and contracts to determine potential impact. The adoption of ASU 2014-09 by the Company will not have a material impact.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 created Subtopic 321-10, Investments-Equity Securities which is applicable to all entities except those in industries that account for substantially all investments at fair value through earnings or the change in net assets. Under this new subtopic, equity securities are generally required to be measured at fair value with unrealized holding gains and losses reflected in net income. ASU 2016-01 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2017. The adoption of ASU 2016-01 by the Company is not expected to have a material impact.

In February 2016, the FASB issued ASU No. 2016-02 (Topic 842), Leases. The ASU provides guidance requiring lessees to recognize right-of-use assets and lease liabilities for all leases other than those that meet the definition of short-term leases. For short-term leases, lessees may elect an accounting policy by class of underlying asset under which these assets and liabilities are not recognized and lease payments are generally recognized over the lease term on a straight-line basis. Under this new ASU, lessees will recognize right-of use assets and lease liabilities for most leases currently accounted for as operating leases under generally accepted accounting principles. For public companies, ASU 2016-02 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is in the process of analyzing a comprehensive list of lease agreements. The adoption of ASU 2016-02 by the Company is not expected to have a material impact.

In March 2016, the FASB issued ASU No. 2016-04, Liabilities - Extinguishments of Liabilities (Subtopic 405-20), Recognition of Breakage for Certain Prepaid Stored-Value Products. ASU 2016-04 applies to all entities that offer certain prepaid stored - value products. The ASU provides guidance for the derecognition of financial liabilities related to the issuance of these products and aligns the recognition of breakage to current authoritative guidance. For public companies, ASU 2016-04 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The adoption of ASU 2016-04 by the Company is not expected to have a material impact.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting. The ASU simplifies several aspects of the accounting for share-based payment transaction, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public companies, ASU 2016-09 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The Company adopted ASU 2016-09 for the period ending March 31, 2017. There was no material impact on the financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (CECL). The ASU changes the way entities recognize impairment of financial assets by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. Under the CECL model, we will be required to present certain financial assets carried at amortized cost, such as loans held for investment and held-to-maturity debt securities, at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement will take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the "incurred loss" model required under current GAAP, which delays recognition until it is probable a loss has been incurred. Accordingly, we expect that the adoption of the CECL model will materially affect how we determine our allowance for loan losses and could require us to significantly increase our allowance. For public companies, ASU 2016-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, early adoption is permitted for the fiscal year beginning after December 15, 2018. The Company is in the process of implementing a software solution to assist in the analysis of historical loan data to determine the CECL model that will be implemented. We expect to recognize a one-time cumulative-effect adjustment to our allowance for loan losses as of the beginning of the first reporting period in which the new standard is adopted. The amount of the one-time cumulative-effect adjustment has not yet been determined.

In January 2017, the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments - Equity Method and Joint Ventures (Topic 323), Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings. This ASU adds an SEC paragraph and amends other Topics pursuant to an SEC staff Announcement made at the September 22, 2016 Emerging Issues Task Force (EITF) meeting. The SEC paragraph applies to ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606); ASU No. 2016-02, Leases (Topic 842); and ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU provides that a company should evaluate ASUs that have not yet been adopted to determine the appropriate financial statement disclosures about the potential material effects of those ASUs on the financial statements when adopted. If the company does not know or cannot reasonably estimate the impact that adoption of the ASUs referenced in this announcement is expected to have on the financial statements, then in addition to making a statement to that effect, the company should consider additional qualitative financial statement disclosures to assist the reader in assessing the significance of the impact that the standard will have on the financial statements of the company when adopted. Additional qualitative disclosures should include a description of the effect of the accounting policies that the company expects to apply and a comparison to the company's current accounting policies. Also, the company should describe the status of its process to implement the new standards and the significant implementation matters yet to be addressed.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 250), Simplifying the Test for Goodwill Impairment. The ASU simplifies the goodwill impairment test by requiring a company to perform its annual or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized when the carrying amount exceeds fair value. For public companies, ASU 2017-04 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of ASU No. 2017-04 by the Company is not expected to have a material impact.

In March 2017, the FASB issued ASU No. 2017-08, Receivable - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities. This ASU shortens the amortization period for certain callable debt securities held at a premium. The premium will be amortized to the earliest call date. For public companies, ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2018. The Company adopted ASU 2017-08 for the period ending March 31, 2017. There was no material impact on the financial statements.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. This ASU requires companies to change the recognition and presentation of the effects of hedge accounting by eliminating the requirement to separately measure and report hedge ineffectiveness and requiring companies to present all of the elements of hedge accounting that affect earnings in the same income statement line as the hedged item. Furthermore, the standard eases the requirements for effectiveness testing, hedge documentation and applying the critical terms match method and introduces new alternatives that will permit companies to reduce the risk of material error corrections if they misapply the shortcut method. For public companies, ASU 2017-12 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2018. The adoption of ASU 2017-12 by the Company is not expected to have a material impact.

Earnings Per Share

Earnings Per Share

Basic earnings per share is computed using the weighted average number of actual common shares outstanding during the period.  Diluted earnings per share reflects the potential dilution that would occur from the exercise of common stock options outstanding.  ESOP shares are considered outstanding for this calculation unless unearned.

The computation of basic and diluted earnings per share for the periods presented is as follows:

The Company considered the following information in reaching the conclusion that the impairments disclosed in the table above are temporary and not other-than-temporary impairments.  None of the unrealized losses in the above table was due to the deterioration in the credit quality of any of the issues that might result in the non-collection of contractual principal and interest.  The unrealized losses are due to changes in interest rates.  The Company has not recognized any unrealized loss in income because management does not have the intent to sell the securities included in the previous table.  Management has concluded that it is more likely than not that the Company will not be required to sell these securities prior to recovery of the amortized cost basis.

The below are descriptions of the credit quality indicators:

Excellent – Excellent rated loans are prime quality loans covered by highly liquid collateral with generous margins or supported by superior current financial conditions reflecting substantial net worth, relative to total credit extended, and based on assets of a stable and non-speculative nature whose values can be readily verified. Identified repayment source or cash flow is abundant and assured.

Good – Good rated loans are adequately secured by readily marketable collateral or good financial condition characterized by liquidity, flexibility and sound net worth. Loans are supported by sound primary and secondary payment sources and timely and accurate financial information.

Satisfactory – Satisfactory rated loans are loans to borrowers of average financial means not especially vulnerable to changes in economic or other circumstances, where the major support for the extension is sufficient collateral of a marketable nature, and the primary source of repayment is seen to be clear and adequate.

Monitor – Monitor rated loans are identified by management as warranting special attention for a variety of reasons that may bear on ultimate collectability. This may be due to adverse trends, a particular industry, loan structure, or repayment that is dependent on projections, or a one-time occurrence.

Special Mention – Special mention rated loans are supported by a marginal payment capacity and are marginally protected by collateral.  There are identified weaknesses that if not monitored and corrected may adversely affect the Company’s credit position.  A special mention credit would typically have a weakness in one of the general categories (cash flow, collateral position or payment history) but not in all categories.

Substandard – Substandard loans are not adequately supported by the paying capacity of the borrower and may be inadequately collateralized.  These loans have a well-defined weakness or weaknesses.  For these loans, it is more probable than not that the Company could sustain some loss if the deficiency(ies) is not corrected.

Past due loans as of September 30, 2017 and December 31, 2016 were as follows:

(1) There were $3.76 million and $4.23 million of TDR loans included within nonaccrual loans as of September 30, 2017 and December 31, 2016, respectively.

Loans 90 days or more past due that are still accruing interest increased $1.16 million from December 31, 2016 to September 30, 2017 due to an increase in the number of loans past due greater than 90 days including a $1.12 agricultural relationship. As of September 30, 2017 there were 10 accruing loans past due 90 days or more. The average balance of accruing loans past due as of September 30, 2017 are $0.18 million. There were 6 accruing loans past due 90 days or more as of December 31, 2016 and the average loan balance was $0.11 million. The accruing loans past due 90 days or more balances are believed to be adequately collateralized and the Company expects to collect all principal and interest as contractually due under these loans.

The Company may modify the terms of a loan to maximize the collection of amounts due.  Such a modification is considered a troubled debt restructuring (“TDR”).  In most cases, the modification is either a reduction in interest rate, conversion to interest only payments or an extension of the maturity date.  The borrower is experiencing financial difficulties or is expected to experience difficulties in the near-term, so a concessionary modification is granted to the borrower that would otherwise not be considered.  TDR loans accrue interest as long as the borrower complies with the revised terms and conditions and has demonstrated repayment performance at a level commensurate with the modified terms over several payment cycles.

Below is a summary of information for TDR loans as of September 30, 2017 and December 31, 2016:

Impaired loans increased $0.12 million from December 31, 2016 to September 30, 2017.  Impaired loans include any loan that has been placed on nonaccrual status, accruing loans past due 90 days or more and TDR loans.  Impaired loans also include loans that, based on management’s evaluation of current information and events, the Company expects to be unable to collect in full according to the contractual terms of the original loan agreement.  Impaired loans were 1.40% of loans held for investment as of September 30, 2017 and 1.48% as of December 31, 2016.  The increase in impaired loans is due mainly to an increase in TDR loans of $3.16 million and an increase in accruing loans past due 90 days or more of $1.16 million from December 31, 2016 to September 30, 2017, and is offset by a decrease in nonaccrual loans of $0.60 million, and a decrease of $3.60 million in relationships with a specific allowance for losses.

The Company regularly reviews a substantial portion of the loans in the portfolio and assesses whether the loans are impaired in accordance with ASC 310.  If the loans are impaired, the Company determines if a specific allowance is appropriate.  In addition, the Company's management also reviews and, where determined necessary, provides allowances for particular loans based upon (1) reviews of specific borrowers and (2) management’s assessment of areas that management considers are of higher credit risk, including loans that have been restructured.  Loans that are determined not to be impaired and for which there are no specific allowances are classified into one or more risk categories. Based upon the risk category assigned, the Company allocates a percentage, as determined by management, for a required allowance needed.  The determination of the appropriate percentage begins with historical loss experience factors, which are then adjusted for levels and trends in past due loans, levels and trends in charged-off and recovered loans, trends in volume growth, trends in problem and watch loans, trends in restructured loans, local economic trends and conditions, industry and other conditions, and effects of changing interest rates.

Specific allowances for losses on impaired loans are established if the loan balances exceed the net present value of the relevant future cash flows or the fair value of the relevant collateral based on updated appraisals and/or updated collateral analysis for the properties if the loan is collateral dependent.  The Company may recognize a charge off or record a specific allowance related to an impaired loan if there is a collateral shortfall or it is unlikely the borrower can make all principal and interest payments as contractually due.

For loans that are collateral dependent, losses are evaluated based on the portion of a loan that exceeds the fair market value of the collateral.  In general, this is the amount that the carrying value of the loan exceeds the related appraised value less estimated costs to sell the collateral.  Generally, it is the Company’s policy not to rely on appraisals that are older than one year prior to the date the impairment is being measured.  The most recent appraisal values may be adjusted if, in the Company’s judgment, experience and other market data indicate that the property’s value, use, condition, exit market or other variable affecting its value may have changed since the appraisal was performed, consistent with the December 2006 joint interagency guidance on the allowance for loan losses.  The charge off or loss adjustment supported by an appraisal is considered the minimum charge off.  Any adjustments made to the appraised value are to provide an additional charge off or specific reserve based on the applicable facts and circumstances.  In instances where there is an estimated decline in value, a specific reserve may be provided or a charge off taken pending confirmation of the amount of the loss from an updated appraisal.  Upon receipt of the new appraisals, an additional specific reserve may be provided or charge off taken based on the appraised value of the collateral.  On average, appraisals are obtained within one month of order.

(1) Considered Level 1 under ASC 820.

(2) Considered Level 2 under ASC 820.

(3) Considered Level 3 under ASC 820 and are based on valuation models that use significant assumptions that are not observable in an active market.

Fair value of financial instruments:  FASB ASC 820, Fair Value Measurements and Disclosures (“ASC 820”) provides a single definition for fair value, a framework for measuring fair value and expanded disclosures concerning fair value.  Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an 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.

The Company determines the fair market value of its financial instruments based on the fair value hierarchy established in ASC 820.  There are three levels of inputs that may be used to measure fair value as follows:

Level 1 Quoted prices in active markets for identical assets or liabilities.

Level 2 Observable inputs other than quoted prices included within Level 1.  Observable inputs include the quoted prices for similar assets or liabilities in markets that are not active and inputs other than quoted prices that are observable for the asset or liability.

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

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 following is a description of valuation methodologies used for assets and liabilities recorded at fair value and for estimating fair value for assets or liabilities not recorded at fair value.

ASSETS

Cash and cash equivalents:  The carrying amounts reported in the consolidated balance sheets for cash and short-term instruments approximate their fair values (Level 1).

Investment securities available for sale:  Investment securities available for sale are recorded at fair value on a recurring basis.  Fair value measurement is based upon quoted prices, if available.  If a quoted price is not available, the fair value is obtained from benchmarking the security against similar securities.  All of the Company’s securities are considered Level 2.

The pricing for investment securities is obtained from an independent source.  There are no level 1 or level 3 investment securities owned by the Company.  The Company obtains an understanding of the independent source’s valuation methodologies used to determine fair value by level of security. The Company validates assigned fair values on a sample basis using an additional third-party provider pricing service to determine if the fair value measurement is reasonable.  Due to the nature of our investment portfolio, we do not expect significant and unusual fluctuations as fair value changes primarily relate to interest rate changes.   No unusual fluctuations were identified during the nine months ended September 30, 2017.   If a fluctuation requiring investigation was identified, the Company would research the change with the independent source or other available information.

Loans held for sale:  Loans held for sale are carried at historical cost.  The carrying amount is a reasonable estimate of fair value because of the short time between origination of the loan and its sale on the secondary market (Level 2).  The market is active for these loans and as a result prices for similar assets are available.

Loans:  The Company does not record loans at fair value on a recurring basis.  For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values (Level 3).  The fair values for other loans are determined using estimated future cash flows, discounted at the interest rates currently being offered for loans with similar terms to borrowers with similar credit quality utilizing an entrance price concept (Level 3).  The Company does record nonrecurring fair value adjustments to loans to reflect (1) partial write-downs that are based on the observable market price or appraised value of the collateral or (2) the full charge-off of the loan carrying value (Level 3).  These loans are considered Level 3 as the instruments used to determine fair market value require significant management judgment and estimation.

Foreclosed assets:  The Company does not record foreclosed assets at fair value on a recurring basis.  Foreclosed assets consist mainly of other real estate owned but may include other types of assets repossessed by the Company.  Foreclosed assets are adjusted to the lower of carrying value or fair value less the cost of disposal.   Fair value is generally based upon independent market prices or appraised values of the collateral, and may include a marketability discount as deemed necessary by management based on its experience with similar types of real estate.  The value of foreclosed assets is evaluated periodically as a nonrecurring fair value adjustment.  Foreclosed assets are classified as Level 3.

Off-balance sheet instruments:  Fair values for outstanding letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties' credit standing.  The fair value of the outstanding letters of credit is not significant. Unfunded loan commitments are not valued since the loans are generally priced at market at the time of funding (Level 2).

Accrued interest receivable:  The fair value of accrued interest receivable equals the amount receivable due to the current nature of the amounts receivable (Level 2).

Non-marketable equity investments:  Non-marketable equity investments are recorded under the cost or equity method of accounting.  There are generally restrictions on the sale and/or liquidation of these investments, including stock of the Federal Home Loan Bank.  The carrying value of stock of the Federal Home Loan Bank approximates fair value (Level 2).

LIABILITIES

Deposit liabilities:  Deposit liabilities are carried at historical cost.  The fair value of demand deposits, savings accounts and certain money market account deposits is the amount payable on demand at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities.  If the fair value of the fixed maturity certificates of deposit is calculated at less than the carrying amount, the carrying value of these deposits is reported as the fair value (Level 2).  Deposit liabilities are classified as Level 2 due to available prices for similar liabilities in the market.

Other borrowings:  Other borrowings are carried at historical cost and include federal funds purchased and securities sold under agreements to repurchase.  The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the liability and its expected realization (Level 2). Other borrowings are classified as Level 2 due to available prices for similar liabilities in the market.

Federal Home Loan Bank borrowings:  Federal Home Loan Bank borrowings are recorded at historical cost.  The fair values of the Company’s Federal Home Loan Bank borrowings are estimated using discounted cash flow analysis, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements (Level 2).  Federal Home Loan Bank borrowings are classified as Level 2 due to available prices for similar liabilities in the market.

Interest Rate Swap Agreements: The fair value is estimated using forward-looking interest rate curves and is calculated using discounted cash flows that are observable or that can be corroborated by observable market data (Level 2).

Accrued interest payable:  The fair value of accrued interest payable equals the amount payable due to the current nature of the amounts payable (Level 2).

Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis

The Company is required to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP.  These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets.  The valuation methodologies used to measure these fair value adjustments are described above.    The following tables present the Company’s assets that are measured at fair value on a nonrecurring basis.

Stock Repurchase Program

Stock Repurchase Program

On July 26, 2005, the Company’s Board of Directors authorized a program to repurchase up to a total of 1,500,000 shares of the Company’s common stock (the “2005 Stock Repurchase Program”).  The Company’s Board of Directors has authorized the 2005 Stock Repurchase Program through December 31, 2018.  The Company expects the purchases pursuant to the 2005 Stock Repurchase Program to be made from time to time in private transactions at a price equal to the most recent quarterly independent appraisal of the shares of the Company’s common stock and with the Board reviewing the overall results of the 2005 Stock Repurchase Program on a quarterly basis.  All purchases made pursuant to the 2005 Stock Repurchase Program since its inception have been made on that basis.  The amount and timing of stock repurchases will be based on various factors, such as the Board’s assessment of the Company’s capital structure and liquidity, the amount of interest shown by shareholders in selling shares of stock to the Company at their appraised value, and applicable regulatory, legal and accounting factors.  The Company has purchased 1,003,216 shares of its common stock in privately negotiated transactions from August 1, 2005 through September 30, 2017.  Of these 1,003,216 shares, 14,538 shares were purchased during the quarter ended September 30, 2017, at an average price per share of $52.80.

Commitments and Contingencies

Commitments and Contingencies

Concentrations of credit risk:  The Bank’s loans, commitments to extend credit, unused lines of credit and outstanding letters of credit have been granted to customers within the Bank's market area.  Investments in securities issued by state and political subdivisions within the state of Iowa totaled approximately $68.95 million.  The concentrations of credit by type of loan are set forth in Note 5 to the Consolidated Financial Statements.  Outstanding letters of credit were granted primarily to commercial borrowers.  Although the Bank has a diversified loan portfolio, a substantial portion of its debtors' ability to honor their contracts is dependent upon the economic conditions in Johnson, Linn and Washington Counties, Iowa.

Contingencies:  In the normal course of business, the Company and Bank are involved in various legal proceedings.  While the ultimate outcome of such legal proceedings cannot be predicted with certainty, after reviewing pending and threatened litigation with counsel, management believes at this time that the outcome of such litigation will not have a material adverse effect on the Company's business, financial condition or results of operations.

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, credit card participations and standby letters of credit.  These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets.

The Bank’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, credit card participations and standby letters of credit is represented by the contractual amount of those instruments.  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 September 30, 2017 and December 31, 2016 is as follows:

	September 30, 2017		December 31, 2016
	(Amounts In Thousands)
Firm loan commitments and unused portion of lines of credit:
Home equity loans	$	54,200	$	48,785

Income Taxes

Income Taxes

Federal income tax expense for the nine months ended September 30, 2017 and 2016 was computed using the consolidated effective federal tax rate.  The Company also recognized income tax expense pertaining to state franchise taxes payable individually by the subsidiary bank.  The Company files a consolidated tax return for federal purposes and separate tax returns for State of Iowa purposes.  The tax years ended December 31, 2016, 2015, and 2014 remain subject to examination by the Internal Revenue Service.  For state tax purposes, the tax years ended December 31, 2016, 2015, and 2014 remain open for examination.  There were no material unrecognized tax benefits at September 30, 2017  and December 31, 2016 and therefore no interest or penalties on unrecognized tax benefits has been recorded.  As of September 30, 2017, the Company does not anticipate any significant increase in unrecognized tax benefits during the twelve-month period ending September 30, 2018. Income taxes as a percentage of income before taxes were 30.48% for the nine months ended September 30, 2017 and 31.40% for the same period in 2016.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

In the normal course of business, the Bank may use derivative financial instruments to manage its interest rate risk.  These instruments carry varying degrees of credit, interest rate and market or liquidity risks.  Derivative instruments are recognized as either assets or liabilities in the accompanying financial statement and are measured at fair value.  The Bank’s objectives are to add stability to its net interest margin and to manage its exposure to movements in interest rates.  The contract or notional amount of a derivative is used to determine, along with the other terms of the derivative, the amount to be exchanged between the counterparties.  The Bank is exposed to credit risk in the event of nonperformance by counterparties to financial instruments.  The Bank minimizes this risk by entering into derivative contracts with large, stable financial institutions.  The Bank has not experienced any losses from nonperformance by counterparties.  The Bank monitors counterparty risk in accordance with the provisions of ASC 815.  In addition, the Bank’s interest rate-related derivative instruments contain language outlining collateral pledging requirements for each counterparty.  Collateral must be posted when the market value exceeds certain threshold limits which are determined by credit ratings of each counterparty.  The Bank was required to pledge $3.46 million of collateral as of September 30, 2017.

Cash Flow Hedges:

The Bank executed two forward-starting interest rate swap transactions on November 7, 2013.  One of the interest rate swap transactions had an effective date of November 9, 2015, and an expiration date of November 9, 2020, effectively converting $25.00 million of variable rate debt to fixed rate debt.  The other interest rate swap transaction had an effective date of November 7, 2016 and an expiration date of November 7, 2023, effectively converting $25.00 million of variable rate debt to fixed rate debt.  For accounting purposes, these swap transactions are designated as a cash flow hedge of the changes in cash flows attributable to changes in three-month LIBOR, the benchmark interest rate being hedged, associated with the interest payments made on an amount of the Bank’s debt principal equal to the then-outstanding swap notional amount.  At inception, the Bank asserted that the underlying principal balance would remain outstanding throughout the hedge transaction making it probable that sufficient LIBOR-based interest payments would exist through the maturity date of the swaps.

The table below identifies the balance sheet category and fair values of the Bank’s derivative instruments designated as cash flow hedges as of September 30, 2017 and December 31, 2016:

	Notional Amount		Fair Value			Balance Sheet Category	Maturity

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation:

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and with instructions for Form 10-Q and Regulation S-X.  These financial statements include all adjustments (consisting of normal recurring accruals) which in the opinion of management are considered necessary for the fair presentation of the financial position and results of operations for the periods shown.  Certain prior year amounts have been reclassified to conform to the current year presentation.  The Company considers that it operates as one business segment, a commercial bank.

Effect of New Financial Accounting Standards

Effect of New Financial Accounting Standards:

In May 2014, The FASB and International Accounting Standards Board (IASB) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of ASU 2014-09 is that a company should recognize revenue to depict the transfer of promised good or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. For financial institutions, significant changes are not expected given that most financial instruments are not in the scope of the accounting standard update. ASU 2014-09 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. In August 2015, FASB issued ASU 2015-14 deferring the effective date for annual periods and interim periods within those annual periods after December 15, 2017. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company has evaluated all of its noninterest income streams and contracts to determine potential impact. The adoption of ASU 2014-09 by the Company will not have a material impact.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 created Subtopic 321-10, Investments-Equity Securities which is applicable to all entities except those in industries that account for substantially all investments at fair value through earnings or the change in net assets. Under this new subtopic, equity securities are generally required to be measured at fair value with unrealized holding gains and losses reflected in net income. ASU 2016-01 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2017. The adoption of ASU 2016-01 by the Company is not expected to have a material impact.

In February 2016, the FASB issued ASU No. 2016-02 (Topic 842), Leases. The ASU provides guidance requiring lessees to recognize right-of-use assets and lease liabilities for all leases other than those that meet the definition of short-term leases. For short-term leases, lessees may elect an accounting policy by class of underlying asset under which these assets and liabilities are not recognized and lease payments are generally recognized over the lease term on a straight-line basis. Under this new ASU, lessees will recognize right-of use assets and lease liabilities for most leases currently accounted for as operating leases under generally accepted accounting principles. For public companies, ASU 2016-02 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is in the process of analyzing a comprehensive list of lease agreements. The adoption of ASU 2016-02 by the Company is not expected to have a material impact.

In March 2016, the FASB issued ASU No. 2016-04, Liabilities - Extinguishments of Liabilities (Subtopic 405-20), Recognition of Breakage for Certain Prepaid Stored-Value Products. ASU 2016-04 applies to all entities that offer certain prepaid stored - value products. The ASU provides guidance for the derecognition of financial liabilities related to the issuance of these products and aligns the recognition of breakage to current authoritative guidance. For public companies, ASU 2016-04 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The adoption of ASU 2016-04 by the Company is not expected to have a material impact.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting. The ASU simplifies several aspects of the accounting for share-based payment transaction, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public companies, ASU 2016-09 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The Company adopted ASU 2016-09 for the period ending March 31, 2017. There was no material impact on the financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (CECL). The ASU changes the way entities recognize impairment of financial assets by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. Under the CECL model, we will be required to present certain financial assets carried at amortized cost, such as loans held for investment and held-to-maturity debt securities, at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement will take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the "incurred loss" model required under current GAAP, which delays recognition until it is probable a loss has been incurred. Accordingly, we expect that the adoption of the CECL model will materially affect how we determine our allowance for loan losses and could require us to significantly increase our allowance. For public companies, ASU 2016-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, early adoption is permitted for the fiscal year beginning after December 15, 2018. The Company is in the process of implementing a software solution to assist in the analysis of historical loan data to determine the CECL model that will be implemented. We expect to recognize a one-time cumulative-effect adjustment to our allowance for loan losses as of the beginning of the first reporting period in which the new standard is adopted. The amount of the one-time cumulative-effect adjustment has not yet been determined.

In January 2017, the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments - Equity Method and Joint Ventures (Topic 323), Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings. This ASU adds an SEC paragraph and amends other Topics pursuant to an SEC staff Announcement made at the September 22, 2016 Emerging Issues Task Force (EITF) meeting. The SEC paragraph applies to ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606); ASU No. 2016-02, Leases (Topic 842); and ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU provides that a company should evaluate ASUs that have not yet been adopted to determine the appropriate financial statement disclosures about the potential material effects of those ASUs on the financial statements when adopted. If the company does not know or cannot reasonably estimate the impact that adoption of the ASUs referenced in this announcement is expected to have on the financial statements, then in addition to making a statement to that effect, the company should consider additional qualitative financial statement disclosures to assist the reader in assessing the significance of the impact that the standard will have on the financial statements of the company when adopted. Additional qualitative disclosures should include a description of the effect of the accounting policies that the company expects to apply and a comparison to the company's current accounting policies. Also, the company should describe the status of its process to implement the new standards and the significant implementation matters yet to be addressed.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 250), Simplifying the Test for Goodwill Impairment. The ASU simplifies the goodwill impairment test by requiring a company to perform its annual or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized when the carrying amount exceeds fair value. For public companies, ASU 2017-04 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of ASU No. 2017-04 by the Company is not expected to have a material impact.

In March 2017, the FASB issued ASU No. 2017-08, Receivable - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities. This ASU shortens the amortization period for certain callable debt securities held at a premium. The premium will be amortized to the earliest call date. For public companies, ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2018. The Company adopted ASU 2017-08 for the period ending March 31, 2017. There was no material impact on the financial statements.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. This ASU requires companies to change the recognition and presentation of the effects of hedge accounting by eliminating the requirement to separately measure and report hedge ineffectiveness and requiring companies to present all of the elements of hedge accounting that affect earnings in the same income statement line as the hedged item. Furthermore, the standard eases the requirements for effectiveness testing, hedge documentation and applying the critical terms match method and introduces new alternatives that will permit companies to reduce the risk of material error corrections if they misapply the shortcut method. For public companies, ASU 2017-12 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2018. The adoption of ASU 2017-12 by the Company is not expected to have a material impact.

Earnings Per Share

Earnings Per Share

Basic earnings per share is computed using the weighted average number of actual common shares outstanding during the period.  Diluted earnings per share reflects the potential dilution that would occur from the exercise of common stock options outstanding.  ESOP shares are considered outstanding for this calculation unless unearned.
