Nature of Activities and Significant Accounting Policies [Abstract]	'
Nature of Activities and Significant Accounting Policies	'
	Note 1.	Nature of Activities and Significant Accounting Policies
	Nature of activities:  Hills Bancorporation (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 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, Washington, Kalona, Wellman, Cedar Rapids and Marion, Iowa.
	The Bank competes with other financial institutions and non-financial institutions providing similar financial products.  Although the loan activity of the Bank is diversified with commercial and agricultural loans, real estate loans, automobile, installment and other consumer loans, the Bank's credit is concentrated in real estate loans.  All of the Company’s operations are considered to be one reportable operating segment.
	Accounting estimates:  The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.
	Certain significant estimates:  The allowance for loan losses, fair values of securities and other financial instruments, and share-based compensation expense involves certain significant estimates made by management.  These estimates are reviewed by management routinely and it is reasonably possible that circumstances that exist at December 31, 2013 may change in the near-term future and that the effect could be material to the consolidated financial statements.
	Principles of consolidation:  The consolidated financial statements include the accounts of the Company and its subsidiary.  All significant intercompany balances and transactions have been eliminated in consolidation.
	Revenue recognition: Interest income on loans and investment securities is recognized on the accrual method. Loan origination fees are recognized when the loans are sold. Trust fees, deposit account service charges and other fees are recognized when the services are provided or when customers use the services.
	Cash and cash equivalents:  The Company considers all investments with original maturities of three months or less to be cash equivalents.  At December 31, 2013 and 2012, cash equivalents consisted primarily of deposits with other banks.
	Investment securities:  Available-for-sale securities consist of debt securities not classified as trading or held to maturity.  Available-for-sale securities are stated at fair value, and unrealized holding gains and losses, net of the related deferred tax effect, are reported as a separate component of stockholders' equity.  There were no trading or held to maturity securities as of December 31, 2013 or 2012.
	Stock of the Federal Home Loan Bank is carried at cost.  The Company has evaluated the stock and determined there is no impairment.
	Premiums and discounts on debt securities are amortized or accreted over the period to maturity of those securities.  The method of amortization results in a constant effective yield on those securities (the interest method).  Realized gains and losses on investment securities are included in income, determined on the basis of the cost of the specific securities sold.
	Declines in the fair value of investment securities available for sale (with certain exceptions for debt securities noted below) that are deemed to be other-than-temporary are charged to earnings as a realized loss, and a new cost basis for the securities is established.  In evaluating other-than-temporary impairment, the Company considers the length of time and extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value in the near term.  Declines in the fair value of debt securities below amortized cost are deemed to be other-than-temporary in circumstances where: (1) the Company has the intent to sell a security; (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security.  If the Company intends to sell a security or if it is more likely than not that the Company will be required to sell the security before recovery, an other-than-temporary impairment write-down is recognized in earnings equal to the difference between the security’s amortized cost basis and its fair value.  If the Company does not intend to sell the security or it is not more likely than not that the Company will be required to sell the security before recovery, the other-than-temporary impairment write-down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in other comprehensive income.  Realized securities gains or losses on securities sales (using specific identification method) and declines in value judged to be other-than-temporary are included in investment securities gains (losses), net, in the consolidated statements of income.
	Loans:  Loans are stated at the amount of unpaid principal, reduced by the allowance for loan losses.  Interest income is accrued on the unpaid balances as earned.
	Loans held for sale are stated at the lower of aggregate cost or estimated fair value.  Loans are sold on a non-recourse basis with servicing released and gains and losses are recognized based on the difference between sales proceeds and the carrying value of the loan.  The Company has had very few experiences of repurchasing loans previously sold into the secondary market.  A specific reserve was not considered necessary based on the Company’s historical experience with repurchase activity.
	The allowance for loan losses is established through a provision for loan losses charged to expense.  Loans are charged against the allowance when management believes the collectability of principal is unlikely.  The allowance for loan losses is maintained at a level considered adequate to provide for probable losses that can be reasonably anticipated.  The allowance is increased by provisions charged to expense and is reduced by net charge-offs.  The Bank makes continuous reviews of the loan portfolio and considers current economic conditions, historical loss experience, review of specific problem loans and other factors in determining the adequacy of the allowance.  Management classifies loans within the following industry standard categories: watch, substandard and loss.
	The policy for charging off loans is consistent throughout all loan categories.  A loan is charged off based on criteria that includes but is not limited to:  delinquency status, financial condition of the entire customer credit line and underlying collateral coverage, economic or external conditions that might impact full repayment of the loan, legal issues, overdrafts, and the customer’s willingness to work with the Company.
	Loans are considered impaired when, based on current information and events, it is probable the Bank will not be able to collect all amounts due.  An impaired loan includes any loan that has been placed on nonaccrual status, loans greater than 90 days past due and still accruing and TDR loans.  They also include loans, based on current information and events, that it is likely the Bank will be unable to collect all amounts due according to the contractual terms of the original loan agreement.  The portion of the allowance for loan losses applicable to impaired loans has been computed based on the present value of the estimated future cash flows of interest and principal discounted at the loans effective interest rate or on the fair value of the collateral for collateral dependent loans.  The entire change in present value of expected cash flows of impaired loans or of collateral value is reported as provision expense in the same manner in which impairment initially was recognized or as a reduction in the amount of provision expense that otherwise would be reported.  Interest income on nonaccrual loans is recognized once principal has been recovered.
	The accrual of interest income on loans is discontinued when, in the opinion of management, there is reasonable doubt as to the borrower's ability to meet payments of interest or principal when they become due, which is generally when a loan is 90 days or more past due.  When a loan is placed on nonaccrual status, all previously accrued and unpaid interest is reversed.  Loans are returned to an accrual status when all of the principal and interest amounts contractually due are brought current and repayment of the remaining contractual principal and interest is expected.   A loan may also return to accrual status if additional collateral is received from the borrower and, in the opinion of management, the financial position of the borrower indicates that there is no longer any reasonable doubt as to the collection of the amount contractually due.  Payment received on nonaccrual loans are applied first to principal.  Once principal is recovered, any remaining payments received are applied to interest income.  As of December 31, 2013, none of the Company’s nonaccrual loans were earning on a cash basis.
	Nonrefundable loan fees and origination costs are deferred and recognized as a yield adjustment over the life of the related loan.
	Troubled debt restructurings (“TDR loans”):  A loan is classified as a troubled debt restructuring when a borrower is experiencing financial difficulties that leads to a restructuring of the loan, and the Company grants concessions to the borrower in the restructuring that it would not otherwise consider.  These concessions may include rate reductions, principal forgiveness, extension of maturity date and other actions intended to minimize potential losses to the Company.  A loan that is modified at a market rate of interest is no longer classified as troubled debt restructuring in the calendar year subsequent to the restructuring if it is in compliance with the modified terms.  Performance prior to the restructuring is considered when assessing whether the borrower can meet the new terms.  At the time of restructuring, the majority of loans included in a troubled debt restructuring are considered nonaccrual loans.  TDR loans are returned to accrual status under the same criteria noted under loans above.
	Transfers of financial assets:  Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
	Credit related financial instruments:  In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit and standby letters of credit.  Such financial instruments are recorded when they are funded.
	Tax credit real estate:  Tax credit real estate represents two multi-family rental properties, three assisted living rental properties, a multi-tenant rental property for persons with disabilities, and a multi-family senior living rental property all which are affordable housing projects as of December 31, 2013.  The Bank has a 99% limited partnership interest in each limited partnership.  The investment in each was completed after the projects had been developed by the general partner.  The properties are recorded at cost less accumulated depreciation.  The Company evaluates the recoverability of the carrying value on a regular basis.  If the recoverability was determined to be in doubt, a valuation allowance would be established by way of a charge to expense.  Depreciation expense is provided on a straight-line basis over the estimated useful life of the assets.  Expenditures for normal repairs and maintenance are charged to expense as incurred.
	The financial condition, results of operations and cash flows of each limited partnership is consolidated in the Company’s consolidated financial statements.  The operations of the properties are not expected to contribute significantly to the Company’s income before income taxes.  However, the properties do contribute in the form of income tax credits, which lowers the Company’s effective tax rate.  Once established, the credits on each property last for ten years and are passed through from the limited partnerships to the Bank and reduces the consolidated federal tax liability of the Company.
	Property and equipment:  Property and equipment is stated at cost less accumulated depreciation.  Depreciation is computed using primarily declining-balance methods over the estimated useful lives of 7-40 years for buildings and improvements and 3-10 years for furniture and equipment.
	Deferred income taxes:  Deferred income taxes are provided under the asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and net operating loss, and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences.  Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases.  Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some or all of the deferred tax assets will not be realized.  Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.   The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained.  Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized.  Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.  Interest and penalties on unrecognized tax benefits are classified as other noninterest expense.  As of December 31, 2013, the Company had no material unrecognized tax benefits.
	Goodwill:  Goodwill represents the excess of cost over the fair value of the net assets acquired, and is not subject to amortization, but requires, at a minimum, annual impairment tests for intangibles that are determined to have an indefinite life.
	Prepaid FDIC insurance:  Prepaid FDIC insurance as of December 31, 2012 represents the remaining 13-quarter FDIC premium prepayment paid by the Bank for the years of 2009 through 2012.  The balance remaining in prepaid FDIC insurance after payment of the FDIC assessments for 2012 was refunded to the Company in June 2013.  The expense for the FDIC insurance is recorded on a quarterly basis as premiums are assessed.
	Other real estate:   Other real estate represents property acquired through foreclosures and settlements of loans.  Property acquired is carried at the lower of the principal amount of the loan outstanding at the time of acquisition, plus any acquisition costs, or the estimated fair value of the property, less disposal costs.  The Bank will obtain updated appraisals to determine the estimated fair value of the property based on the type of collateral securing the loan and the date of the latest appraisal.  Subsequent write downs estimated on the basis of later valuations are charged to net loss on sale of other real estate owned and other repossessed assets.  Net expenses incurred in maintaining such properties are charged to other non-interest expense.
	Derivative financial instruments:  The Bank uses interest rate swaps as part of its interest rate risk management.  FASB Accounting Standards Codification (ASC) Topic 815 establishes accounting and reporting standards for derivative instruments and hedging activities.  The Bank records all interest rate swaps on the balance sheet at fair value.  Derivatives used to hedge the exposure to variability in expected future cash flows are considered cash flow hedges.  To qualify for hedge accounting, the Bank must comply with the detailed rules and documentation requirements at the inception of the hedge, and hedge effectiveness is assessed at inception and periodically throughout the life of the hedging relationship.
	For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivatives is initially reported in other comprehensive income and subsequently reclassified to interest income or expense when the hedged transaction affects earnings, while the ineffective portion of changes in fair value of the derivative, if any, is recognized immediately in other noninterest income.  The Bank assesses the effectiveness of each hedging relationship by comparing the cumulative changes in cash flows of the derivative hedging instruments with the cumulative changes in cash flows of the designated hedged item or transaction.  No component of the change in the fair value of the hedging instrument is excluded from the assessment of hedge effectiveness.
	The Bank does not use derivatives for trading or speculative purposes.
	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 following table presents calculations of earnings per share:
			Year Ended December 31,
			2013			2012			2011
			(Amounts In Thousands, except share and per share data)
	Computation of weighted average number of basic and diluted shares:
	Common shares outstanding at the beginning of the year			4,712,328			4,727,104			4,398,337
	Weighted average number of net shares (redeemed) issued			(2,110	)		(11,116	)		52,461
	Weighted average shares outstanding (basic)			4,710,218			4,715,988			4,450,798
	Weighted average of potential dilutive shares attributable to stock options granted, computed under the treasury stock method			3,635			5,289			7,724
	Weighted average number of shares (diluted)			4,713,853			4,721,277			4,458,522
	Net income		$	25,931		$	26,833		$	26,777
	Earnings per share:
	Basic		$	5.51		$	5.69		$	6.02
	Diluted		$	5.5		$	5.68		$	6.01
	Stock awards and options:   Compensation expense for stock issued through the stock award plan is accounted for using the fair value method prescribed by FASB ASC 718, “Share-Based Payment” (“ASC 718”).  Under this method, compensation expense is measured and recognized for all stock-based awards made to employees and directors based on the fair value of each option as of the date of the grant.
	Common stock held by ESOP:  The Company's maximum cash obligation related to these shares is classified outside stockholders' equity because the shares are not readily traded and could be put to the Company for cash.
	Treasury Stock:  Treasury stock is accounted for by the cost method, whereby shares of common stock reacquired are recorded at their purchase price.
	Trust Department Assets:  Property held for customers in fiduciary or agency capacities is not included in the accompanying balance sheet, as such items are not assets of the Company.
	Effect of New Financial Accounting Standards:
	In July 2012, the FASB issued ASU 2012-02, Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment, which permits an entity to make a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset, other than goodwill, is impaired.   Under the new standard, if an entity concludes, based on an evaluation of all relevant qualitative factors, that it is not more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, it will not be required to perform the quantitative impairment test for that asset.  The standard is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted.  The adoption of this standard did not have a material impact on the consolidated financial statements.
	In February 2013, the FASB issued ASU 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income, to improve the transparency of reporting reclassification out of accumulated other comprehensive income.  The new standard is effective for reporting periods beginning after December 15, 2012, and the amendments should be prospectively applied.  The amendments do not change the current requirement for reporting net income or other comprehensive income.  The amendments require an organization to present on the face of the financial statements or in the footnotes the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income if the item reclassified is required to be reclassified to net income in its entirety in the same reporting period.  Additionally, for other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required to provide additional detail about those amounts.  The adoption of this standard did not have a material impact on the consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-01 to amend FASB ASC Topic 323, Investments – Equity Method and Joint Ventures.  The objective of this standard is to provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit.  The amendments in the standard permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met.  Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit).  The standard will be effective for the Company beginning January 1, 2015; however, early adoption is permitted.  The Company does have significant investments in such qualified affordable housing projects and is currently reviewing the provisions of this standard to determine what, if any, impacts it may have on the Company’s financial position or results of operations.

	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.  The state and political subdivision securities with gross unrealized losses greater than 12 months as of December 31, 2013 included two issues.  The two securities are municipal bonds rated Ba2.  Bonds with a Ba2 rating are less than investment grade.   The aggregate fair value of these Ba2 rated bonds is $0.49 million while their amortized cost is $0.50 million, representing an unrealized loss of $0.01 million.  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:
Pass – Pass rated loans are supported by sound payment capacity, are adequately collateralized and have no apparent weaknesses that would affect the full repayment of the loan under the established terms and conditions.
Potential Watch – Potential watch rated loans are supported by adequate payment capacity, are adequately collateralized and are performing according to the established terms and conditions.  However, the loan requires more than average monitoring due to a potential weakness.  The potential watch indicator assists the Company in identifying and monitoring loans for which credit quality could deteriorate.
Watch – Watch rated loans are supported by a marginal payment capacity and are marginally collateralized.  There are identified weaknesses that if not monitored and corrected may adversely affect the Company’s credit position.  A watch 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.

The Company does not have a significant amount of loans that are past due less than 90 days where there are serious doubts as to the ability of the borrowers to comply with the loan repayment terms.
Accruing loans past due 90 days or more decreased $1.68 million from December 31, 2012 to December 31, 2013.  Real estate loans make up all of the nonaccrual loans as of December 31, 2013.  As of December 31, 2013 and 2012, accruing loans past due 90 days or more were 0.05% and 0.15% of total loans, respectively.  The average balance of the past due loans also decreased in 2013 as compared to 2012.  The average 90 days or more past due loan balance per loan was $0.08 million as of December 31, 2013 compared to $0.11 million as of December 31, 2012.  The loans 90 days or more past due and still accruing are believed to be adequately collateralized.   Loans are placed on nonaccrual status when management believes the collection of future principal and interest is not reasonably assured.

-1	There were $2.72 million and $2.69 million of TDR loans included within nonaccrual loans as of December 31, 2013 and 2012, respectively.
-2	There were $0.00 million and $0.26 million of TDR loans within accruing loans past due 90 days or more as of December 31, 2013 and 2012, respectively.
The Company may modify the terms of a loan to maximize the collection of amounts due.  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 financial 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.

The Bank has commitments to lend additional borrowings to TDR loan customers.  These commitments are in the normal course of business and allow the borrowers to build pre-sold homes and commercial property and which increase their overall cash flow.  The additional borrowings are not used to facilitate payments on these loans.
There were no TDR loans modified during the year that were in payment default (defined as past due 90 days or more) as of December 31, 2013.

Impaired loans decreased by $3.23 million from December 31, 2012 to December 31, 2013.  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 Bank expects to be unable to collect in full according to the contractual terms of the original loan agreement.  The decrease in impaired loans is due mainly to a decrease in accruing loans past due 90 days or more of $1.68 million from December 31, 2012 to December 31, 2013.
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 that can be identified as uncollectible.  In general, this is the amount that the carrying value of the loan exceeds the related appraised value.  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 additional charge off or loss allocations based on the applicable facts and circumstances.  In instances where there is an estimated decline in value, either a loss allocation is 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 loss allocation 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.
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 helping to determine 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.
The Bank regularly reviews loans in the portfolio and assesses whether the loans are impaired in accordance with ASC 310.  If the loans are impaired, the Bank determines if a specific allowance is appropriate.  In addition, the Bank'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 Bank allocates a percentage, as determined by management, for a required allowance needed.  The determination concerning 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 TDR loans, local economic trends and conditions, industry and other conditions, and effects of changing interest rates.

	The weighted average interest rate on short-term borrowings outstanding as of December 31, 2013 and 2012 was 0.29% and 0.34%, respectively.
	Customer repurchase agreements are used by the Bank to acquire funds from customers where the customer is required or desires to have their funds supported by collateral consisting of investment securities.  The repurchase agreement is a commitment to sell these securities to a customer at a certain price and repurchase them at a future date at that same price plus interest accrued at an agreed upon rate.  The Bank uses customer repurchase agreements in its liquidity plan as well as an accommodation to customers.  At December 31, 2013, $42.02 million of securities sold under repurchase agreements with a weighted average interest rate of 0.29%, maturing in 2014, were collateralized by investment securities having an amortized cost of $42.02 million.

	All of the borrowings are callable by the FHLB with call dates during 2014.  The advances are unlikely to be called unless rates would increase significantly.  The borrowings with the FHLB have prepayment fees associated with them; therefore, the Company cannot prepay without incurring fees.
	To participate in the FHLB advance program, the Company is required to have an investment in FHLB stock.  The Company’s investment in FHLB stock was $7.58 million and $8.06 million at December 31, 2013 and 2012, respectively.  Collateral is provided by the Company’s 1 to 4 family mortgage loans totaling $168.75 million at December 31, 2013 and $168.75 million at December 31, 2012.  The Company also has the ability to borrow against commercial real estate and multi-family loans totaling $167.35 million as of December 31, 2013 and $152.29 million as of December 31, 2012 and there was $0 borrowed against this collateral as of December 31, 2013 or 2012.
	The Bank prepaid $60.00 million of Federal Home Loan Bank borrowings during the year ended December 31, 2012 as part of a strategy to utilize the Bank’s liquidity, improve net interest margin and decrease interest rate risk in the future.  As a result, the Bank incurred a one-time prepayment penalty of $5.93 million, which it recorded as loss on extinguishment of debt.

Employee Benefit Plans [Abstract]	'
Employee Benefit Plans	'
	Note 9.	Employee Benefit Plans
	The Company’s Board of Directors and its stockholders adopted in April 2012 the Hills Bancorporation Employee Stock Purchase Plan (the “ESPP”).  For each quarterly offering period, eligible employees can elect to contribute from 1% to 15% of his or her compensation.  The purchase price is the lesser of the fair market value on the first day of the offering period or the last day of the offering period.  The maximum dollar amount any one employee can elect to contribute in an offering period is $10,000.  During the year ended December 31, 2013, 2,072 shares of stock were purchased by employees of the Bank through the ESPP.  375 shares of stock were purchased by employees of the Bank through the ESPP for the year ended December 31, 2012.
	The Company has an Employee Stock Ownership Plan (the "ESOP") to which it makes discretionary cash contributions.  The Company's contribution to the ESOP totaled $1.57 million, $1.49 million and $1.45 million for the years ended December 31, 2013, 2012 and 2011, respectively.  The 2013, 2012 and 2011 discretionary contribution rates were 9% of qualified salaries.
	During the year ended December 31, 2011, the ESOP purchased an additional 40,028 shares of common stock in the Company with a loan from the Company.  The note payable bears interest at the prime rate subject to a floor of 5.0% with principal and interest payable annually for five consecutive years.  The loan is collateralized by the unreleased shares of stock purchased as well as a certificate of deposit the Company holds at the Bank in the original amount of the note.  The note payable and certificate of deposit are not included in the consolidated balance sheet. There was no interest income or expense recognized in the consolidated statement of income.
	As the note payable is repaid by the ESOP, shares are released from collateral and allocated to qualified employees based on the proportion of principal and interest paid in the year to total principal and interest payments anticipated for the life of the loan.  The number of shares released from collateral totaled 8,360, 8,724 and 7,314 shares for the years ended December 31, 2013, 2012 and 2011, respectively. The shares pledged as collateral are reported as a reduction of stockholder’s equity in the consolidated balance sheet.  As shares are committed to be released from collateral, the Company reports compensation expense equal to the current market price of the shares, and the shares become outstanding for earnings per share computations.  Unallocated shares were 15,630, 23,990 and 32,714 as of December 31, 2013, 2012 and 2011, respectively. Dividends on allocated ESOP shares are recorded as a reduction of retained earnings.  Dividends on unallocated ESOP shares are used to reduce debt.
	In the event a terminated plan participant desires to sell his or her shares of the Company stock, or for certain employees who elect to diversify their account balances, the Company may be required to purchase the shares from the participant at their fair value.  To the extent that shares of common stock held by the ESOP are not readily traded, a sponsor must reflect the maximum cash obligation related to those securities outside of stockholders' equity.  The Company obtains a quarterly independent appraisal of the shares of stock.  As of December 31, 2013 and 2012, the shares held by the ESOP, fair value and maximum cash obligation were as follows:
			2013				2012
	Shares held by the ESOP			394,323				438,778
	Fair value per share		$	75			$	70
	Maximum cash obligation		$	29,574,000			$	30,715,000
	The Company has a profit-sharing plan with a 401(k) feature, which provides for discretionary annual contributions in amounts to be determined by the Board of Directors.  The Company did not make a profit sharing plan contribution in the years ended December 31, 2013, 2012, and 2011. The Company made matching contributions under its 401(k) plan of $0.15 million in 2013, $0.14 million in 2012, and $0.14 million in 2011 and each such amount is included in salaries and employee benefits.
	The Company provides a deferred compensation program for executive officers.  This program allows executive officers to elect to defer a portion of their salaried compensation for payment by the Company at a subsequent date.  The executive officers can defer up to 30% of their base compensation and up to 100% of any bonus into the deferral plan.  Any amount so deferred is credited to the executive officer’s deferred compensation account and converted to units equivalent in value to the fair market value of a share of stock in Hills Bancorporation.  The “stock units” are book entry only and do not represent an actual purchase of stock.  The executive officer’s account is adjusted each year for dividends paid and the change in the market value of Hills Bancorporation stock.  The deferrals and earnings grow tax deferred until withdrawn from the plan.  Earnings credited to the individual’s accounts are recorded as compensation expense when earned.  The deferred compensation liability is recorded in other liabilities and totals $4.63 million and $4.37 million at December 31, 2013 and 2012, respectively.  Expense related to the deferred compensation plan was $0.39 million for 2013, $0.45 million for 2012 and $0.38 million for 2011 and is included in salaries and employee benefits expense.
	The Company also provides a deferred compensation program for its Board of Directors.  Under the plan, each director may elect to defer up to 50% of such director’s cash compensation from retainers and meeting fees for payment by the Company at a subsequent date.  Any amount so deferred is credited to the director’s deferred compensation account and converted to units equivalent in value to the fair market value of a share of stock in Hills Bancorporation.  The “stock units” are book entry only and do not represent an actual purchase of stock.  The director’s account is adjusted each year for dividends paid and the change in the market value of Hills Bancorporation stock.  The deferred compensation liability for the directors’ plan is recorded in other liabilities and totaled $2.10 million and $1.99 million at December 31, 2013 and 2012, respectively.  Expense related to the directors’ deferred compensation plan was $0.17 million for 2013, $0.20 million for 2012 and $0.17 million for 2011 and is included in other noninterest expense.
	The Company has a Stock Option and Incentive Plan for certain key employees and directors whereby shares of common stock have been reserved for awards in the form of stock options or restricted stock awards. Under the plan, the aggregate number of options and shares granted cannot exceed 94,000 shares. A Stock Option Committee may grant options at prices equal to the fair value of the stock at the date of the grant. Options expire 10 years from the date of the grant. Director options granted on or before December 31, 2006 may be exercised immediately.  Director options granted on or after January 1, 2007, and officers' rights under the plan vest over a five-year period from the date of the grant.
	A summary of the stock options is as follows:
			Number of Shares				Weighted-				Weighted-Average			Aggregate
							Average				Remaining			Intrinsic Value
							Exercise Price				Contractual Term			(In Thousands)
											(Years)
	Balance, December 31, 2010			27,955			$	33.83				2.84		$	946

	Exercised			(5,355	)
	Balance, December 31, 2013			12,630			$	53.95				4.72		$	681
	There were 5,110 stock options granted in 2012 and no stock options granted in 2013 or 2011.  The weighted-average fair value of options granted in 2012 was $24.89 per share.  The intrinsic value of options exercised was $0.18 million, $0.23 million and $0.26 million for 2013, 2012 and 2011, respectively.
	The fair value of each option is estimated as of the date of grant using a Black Scholes option pricing model.  The expected lives of options granted incorporate historical employee exercise behavior.  The risk-free rate for periods that coincide with the expected life of the options is based on the ten year interest rate swap rate as published by the Federal Reserve Bank on the date of issuance.  Expected volatility is based on volatility levels of the Company’s peers’ common stock as the Company’s stock has limited trading activity.  Expected dividend yield was based on historical dividend rates. Significant assumptions at date of grant include:
			2013				9-Oct-12				24-Apr-12			2011
	Risk-free interest rate			n/	a			1.77	%			2.08	%		n/	a

	Expected dividends			n/	a			1.64	%			1.64	%		n/	a
	Other pertinent information related to the options outstanding at December 31, 2013 is as follows:
	Exercise Price				Number Outstanding			Remaining Contractual Life		Number Exercisable
	$	34.5				2,940		4 months			2,940

	$	69				1,500		106 months			-
						12,630					7,520
	As of December 31, 2013, the outstanding options have a weighted-average exercise price of $53.95 per share and a weighted average remaining contractual term of 4.72 years.  There was $0.09 million in unrecognized compensation cost for stock options granted under the plan as of December 31, 2013.  This cost is expected to be recognized over a weighted-average period of 3.45 years.
	As of December 31, 2013, the vested options totaled 7,520 shares with a weighted-average exercise price of $45.16 per share and a weighted-average remaining contractual term of 2.18 years.  There were 4,580 shares that vested in 2012 and no shares that vested in 2013 and 2011.  The fair value of the 4,580 options vested during 2012 was $0.31 million.
	As of December 31, 2013, 73,127 shares were available for stock options and awards.  The Compensation and Incentive Stock Committee is also authorized to grant awards of restricted common stock, and it authorized the issuance of 3,584 shares of common stock in 2013, 6,885 shares in 2012 and 6,629 shares in 2011 to certain employees.  The vesting period for these awards is five years and the Bank amortizes the expense on a straight line basis during the vesting period.  The expense relating to these awards for the years ended December 31, 2013, 2012 and 2011 was $0.21 million, $0.17 million and $0.10 million, respectively.

	Temporary differences between the amounts reported in the consolidated financial statements and the tax basis of assets and liabilities result in deferred taxes.  Deferred tax assets and liabilities at December 31, 2013 and 2012 were as follows:

	Gross deferred tax liabilities			4,523				5,849
	Net deferred income tax assets		$	8,605			$	7,144
	The Company has recorded a deferred tax asset for the future tax benefits of Iowa net operating loss carry-forwards.  The net operating loss carry-forwards are generated by the Company largely from its investment in tax credit real estate properties.  The Company is required to file a separate Iowa tax return and cannot be consolidated with the Bank.  The net operating loss carry-forwards will expire, if not utilized, between 2014 and 2034.  The Company has recorded a valuation allowance to reduce the deferred tax asset attributable to the net operating loss carry-forwards.  At December 31, 2013 and 2012, the Company believes it is more likely than not that the Iowa net operating loss carry-forwards will not be realized.  The increase in net operating loss carry-forward in 2013 compared to 2012 reflects the additional Iowa income tax net operating loss generated during 2013 less any expiring carry-forward.  A valuation allowance related to the remaining deferred tax assets has not been provided because management believes it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets.
	The valuation allowance increased by $7,000 and $37,000 for the years ended December 31, 2013 and 2012, respectively.
	The net change in the deferred income taxes for the years ended December 31, 2013, 2012 and 2011 is reflected in the consolidated financial statements as follows:
			Year Ended December 31,

	Income tax expense for the years ended December 31, 2013, 2012 and 2011 are less than the amounts computed by applying the maximum effective federal income tax rate to the income before income taxes because of the following items:

Regulatory Capital Requirements, Restrictions on Subsidiary Dividends and Cash Restrictions [Abstract]	'
Regulatory Capital Requirements, Restrictions on Subsidiary Dividends and Cash Restrictions	'
	Note 11.	Regulatory Capital Requirements, Restrictions on Subsidiary Dividends and Cash Restrictions
	The Company and the Bank are subject to various regulatory capital requirements administered by the federal and state banking agencies.  Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial results.  Under capital adequacy guidelines and the regulatory frameworks for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices.  Capital amounts and classifications of the Company and the Bank are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.
	Quantitative measures established by the regulations to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the tables that follow) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined).  Management believes that, as of December 31, 2013 and 2012, the Company and the Bank met all capital adequacy requirements to which they are subject.
	As of December 31, 2013, the most recent notifications from the Federal Reserve System categorized the Bank as well capitalized under the regulatory framework for prompt corrective action.  To be categorized as well capitalized, the Bank must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table that follows.  There are no conditions or events since that notification that management believes have changed the institution’s category.
	The actual amounts and capital ratios as of December 31, 2013 and 2012, with the minimum regulatory requirements for the Company and Bank are presented below (amounts in thousands):

	Leverage ratio			247,757		11.82			4			5
	The ability of the Company to pay dividends to its stockholders is dependent upon dividends paid by the Bank.  The Bank is subject to certain statutory and regulatory restrictions on the amount it may pay in dividends.  To maintain acceptable capital ratios in the Bank, certain of its retained earnings are not available for the payment of dividends.  To maintain a ratio of capital to assets of 8%, retained earnings of $96.58 million as of December 31, 2013 are available for the payment of dividends to the Company.
	The Bank is required to maintain reserve balances in cash or with the Federal Reserve Bank.  Reserve balances totaled $15.27 million and $54.42 million as of December 31, 2013 and 2012, respectively.
	In July 2013, the Officer of the Comptroller of the Currency and Board of Governors of the Federal Reserve System adopted a final rule implementing agreements reached by the Basel Committee on Banking Supervision in “Basel III: A Global Regulatory Framework for More Resilient Banks and Banking Systems”(BASEL III).   The final rule also adopts 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.  The rule implements a revised definition of regulatory capital, a new 4.50% common equity tier 1 minimum capital requirement, a 6.00% tier 1 capital requirement, and a tier 1 risk-based capital ratio of 8.00%.   The Company expects to remain categorized as well capitalized under the final rule when it becomes effective on January 1, 2015.

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.  Recent market conditions have led to diminished, and in some cases, non-existent trading in certain of the financial asset classes.  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.  Despite the Company’s best efforts to maximize the use of relevant observable inputs, the current market environment has diminished the observability of trades and assumptions that have historically been available.
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 year ended December 31, 2013.   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.
Short-term borrowings:  Short-term 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).  Short-term 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 analyses, 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.
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).

There were no transfers between Levels 1, 2 or 3 during the year ended December 31, 2013.
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.  For assets measured at fair value on a nonrecurring basis in 2013 that were still held on the balance sheet at December 31, 2013, the following table provides the level of valuation assumptions used to determine the adjustment and the carrying value of the related individual assets at year end.

During the year ended December 31, 2012 the Company revised the classification of impaired loans and foreclosed assets from previous filings.  In previous filings, the Company classified impaired loans and foreclosed assets as Level 2 under ASC 820.  The Company revised the classification to Level 3 as the determination of fair value requires significant management judgment or estimation due to the inherent subjectivity of the inputs used to determine value.  The resulting change in presentation does not have a material impact on the Company’s financial position.

Commitments and Contingencies	12 Months Ended
	Dec. 31, 2013
Commitments and Contingencies [Abstract]	'
Commitments and Contingencies	'
	Note 15.	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 $73.87 million.  The concentrations of credit by type of loan are set forth in Note 3 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.  In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the accompanying consolidated financial statements.
	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 December 31, 2013 and 2012 is as follows:
			2013		2012
			(Amounts In Thousands)
	Firm loan commitments and unused portion of lines of credit:
	Home equity loans		$	38,243	$	36,030
	Credit cards			44,326		44,554
	Commercial, real estate and home construction			106,241		96,326
	Commercial lines and real estate purchase loans			172,135		167,210
	Outstanding letters of credit			11,019		10,778
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract.  Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.  The Bank evaluates each customer's credit worthiness on a case-by-case basis.  The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management's credit evaluation of the party.  Collateral held varies, but may include accounts receivable, crops, livestock, inventory, property and equipment, residential real estate and income-producing commercial properties.  Credit card participations are the unused portion of the holders' credit limits.  Such amounts represent the maximum amount of additional unsecured borrowings.
	Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party.  Those guarantees are primarily issued to support public and private borrowing arrangements and, generally, have terms of one year, or less.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers.  The Bank holds collateral, which may include accounts receivable, inventory, property, equipment, and income-producing properties, supporting those commitments if deemed necessary.  In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Bank would be required to fund the commitment.  The maximum potential amount of future payments the Bank could be required to make is represented by the contractual amount shown in the summary above.  If the commitment is funded the Bank would be entitled to seek recovery from the customer.  At December 31, 2013 and 2012, no amounts have been recorded as liabilities for the Bank’s potential obligations under these guarantees.
	Lease commitments: The Company leases certain facilities under operating leases.  The minimum future rental commitments as of December 31, 2013 for all non-cancelable leases relating to Bank premises were as follows:
	Year ending December 31:		(Amounts In Thousands)
	2014		$	437

	Rent expense was $0.33 million, $0.31 million and $0.33 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Note 17.

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 outline 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 not required to pledge any collateral as of December 31, 2013.

Cash Flow Hedges:

The Bank executed two forward-starting interest rate swap transactions on November 7, 2013.  One of the interest rate swap transactions has an effective date of November 9, 2015, and an expiration date of November 9, 2020, to effectively convert $25.00 million of variable rate debt to fixed rate debt.  The other interest rate swap transaction has an effective date of November 7, 2016 and an expiration date of November 7, 2023, also to effectively convert $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.

Nature of Activities and Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Nature of Activities and Significant Accounting Policies [Abstract]	'
Nature of activities	'
	Nature of activities:  Hills Bancorporation (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 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, Washington, Kalona, Wellman, Cedar Rapids and Marion, Iowa.
	The Bank competes with other financial institutions and non-financial institutions providing similar financial products.  Although the loan activity of the Bank is diversified with commercial and agricultural loans, real estate loans, automobile, installment and other consumer loans, the Bank's credit is concentrated in real estate loans.  All of the Company’s operations are considered to be one reportable operating segment.
Accounting estimates	'
	Accounting estimates:  The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.
Certain significant estimates	'
	Certain significant estimates:  The allowance for loan losses, fair values of securities and other financial instruments, and share-based compensation expense involves certain significant estimates made by management.  These estimates are reviewed by management routinely and it is reasonably possible that circumstances that exist at December 31, 2013 may change in the near-term future and that the effect could be material to the consolidated financial statements.
Principles of consolidation	'
	Principles of consolidation:  The consolidated financial statements include the accounts of the Company and its subsidiary.  All significant intercompany balances and transactions have been eliminated in consolidation.
Revenue recognition	'
	Revenue recognition: Interest income on loans and investment securities is recognized on the accrual method. Loan origination fees are recognized when the loans are sold. Trust fees, deposit account service charges and other fees are recognized when the services are provided or when customers use the services.
Cash and cash equivalents	'
	Cash and cash equivalents:  The Company considers all investments with original maturities of three months or less to be cash equivalents.  At December 31, 2013 and 2012, cash equivalents consisted primarily of deposits with other banks.
Investment securities	'
	Investment securities:  Available-for-sale securities consist of debt securities not classified as trading or held to maturity.  Available-for-sale securities are stated at fair value, and unrealized holding gains and losses, net of the related deferred tax effect, are reported as a separate component of stockholders' equity.  There were no trading or held to maturity securities as of December 31, 2013 or 2012.
	Stock of the Federal Home Loan Bank is carried at cost.  The Company has evaluated the stock and determined there is no impairment.
	Premiums and discounts on debt securities are amortized or accreted over the period to maturity of those securities.  The method of amortization results in a constant effective yield on those securities (the interest method).  Realized gains and losses on investment securities are included in income, determined on the basis of the cost of the specific securities sold.
	Declines in the fair value of investment securities available for sale (with certain exceptions for debt securities noted below) that are deemed to be other-than-temporary are charged to earnings as a realized loss, and a new cost basis for the securities is established.  In evaluating other-than-temporary impairment, the Company considers the length of time and extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value in the near term.  Declines in the fair value of debt securities below amortized cost are deemed to be other-than-temporary in circumstances where: (1) the Company has the intent to sell a security; (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security.  If the Company intends to sell a security or if it is more likely than not that the Company will be required to sell the security before recovery, an other-than-temporary impairment write-down is recognized in earnings equal to the difference between the security’s amortized cost basis and its fair value.  If the Company does not intend to sell the security or it is not more likely than not that the Company will be required to sell the security before recovery, the other-than-temporary impairment write-down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in other comprehensive income.  Realized securities gains or losses on securities sales (using specific identification method) and declines in value judged to be other-than-temporary are included in investment securities gains (losses), net, in the consolidated statements of income.
Loans	'
	Loans:  Loans are stated at the amount of unpaid principal, reduced by the allowance for loan losses.  Interest income is accrued on the unpaid balances as earned.
	Loans held for sale are stated at the lower of aggregate cost or estimated fair value.  Loans are sold on a non-recourse basis with servicing released and gains and losses are recognized based on the difference between sales proceeds and the carrying value of the loan.  The Company has had very few experiences of repurchasing loans previously sold into the secondary market.  A specific reserve was not considered necessary based on the Company’s historical experience with repurchase activity.
	The allowance for loan losses is established through a provision for loan losses charged to expense.  Loans are charged against the allowance when management believes the collectability of principal is unlikely.  The allowance for loan losses is maintained at a level considered adequate to provide for probable losses that can be reasonably anticipated.  The allowance is increased by provisions charged to expense and is reduced by net charge-offs.  The Bank makes continuous reviews of the loan portfolio and considers current economic conditions, historical loss experience, review of specific problem loans and other factors in determining the adequacy of the allowance.  Management classifies loans within the following industry standard categories: watch, substandard and loss.
	The policy for charging off loans is consistent throughout all loan categories.  A loan is charged off based on criteria that includes but is not limited to:  delinquency status, financial condition of the entire customer credit line and underlying collateral coverage, economic or external conditions that might impact full repayment of the loan, legal issues, overdrafts, and the customer’s willingness to work with the Company.
	Loans are considered impaired when, based on current information and events, it is probable the Bank will not be able to collect all amounts due.  An impaired loan includes any loan that has been placed on nonaccrual status, loans greater than 90 days past due and still accruing and TDR loans.  They also include loans, based on current information and events, that it is likely the Bank will be unable to collect all amounts due according to the contractual terms of the original loan agreement.  The portion of the allowance for loan losses applicable to impaired loans has been computed based on the present value of the estimated future cash flows of interest and principal discounted at the loans effective interest rate or on the fair value of the collateral for collateral dependent loans.  The entire change in present value of expected cash flows of impaired loans or of collateral value is reported as provision expense in the same manner in which impairment initially was recognized or as a reduction in the amount of provision expense that otherwise would be reported.  Interest income on nonaccrual loans is recognized once principal has been recovered.
	The accrual of interest income on loans is discontinued when, in the opinion of management, there is reasonable doubt as to the borrower's ability to meet payments of interest or principal when they become due, which is generally when a loan is 90 days or more past due.  When a loan is placed on nonaccrual status, all previously accrued and unpaid interest is reversed.  Loans are returned to an accrual status when all of the principal and interest amounts contractually due are brought current and repayment of the remaining contractual principal and interest is expected.   A loan may also return to accrual status if additional collateral is received from the borrower and, in the opinion of management, the financial position of the borrower indicates that there is no longer any reasonable doubt as to the collection of the amount contractually due.  Payment received on nonaccrual loans are applied first to principal.  Once principal is recovered, any remaining payments received are applied to interest income.  As of December 31, 2013, none of the Company’s nonaccrual loans were earning on a cash basis.
	Nonrefundable loan fees and origination costs are deferred and recognized as a yield adjustment over the life of the related loan.
Troubled debt restructurings ("TDR Loans")	'
	Troubled debt restructurings (“TDR loans”):  A loan is classified as a troubled debt restructuring when a borrower is experiencing financial difficulties that leads to a restructuring of the loan, and the Company grants concessions to the borrower in the restructuring that it would not otherwise consider.  These concessions may include rate reductions, principal forgiveness, extension of maturity date and other actions intended to minimize potential losses to the Company.  A loan that is modified at a market rate of interest is no longer classified as troubled debt restructuring in the calendar year subsequent to the restructuring if it is in compliance with the modified terms.  Performance prior to the restructuring is considered when assessing whether the borrower can meet the new terms.  At the time of restructuring, the majority of loans included in a troubled debt restructuring are considered nonaccrual loans.  TDR loans are returned to accrual status under the same criteria noted under loans above.
Transfers of financial assets	'
	Transfers of financial assets:  Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Credit related financial instruments	'
	Credit related financial instruments:  In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit and standby letters of credit.  Such financial instruments are recorded when they are funded.
Tax credit real estate	'
	Tax credit real estate:  Tax credit real estate represents two multi-family rental properties, three assisted living rental properties, a multi-tenant rental property for persons with disabilities, and a multi-family senior living rental property all which are affordable housing projects as of December 31, 2013.  The Bank has a 99% limited partnership interest in each limited partnership.  The investment in each was completed after the projects had been developed by the general partner.  The properties are recorded at cost less accumulated depreciation.  The Company evaluates the recoverability of the carrying value on a regular basis.  If the recoverability was determined to be in doubt, a valuation allowance would be established by way of a charge to expense.  Depreciation expense is provided on a straight-line basis over the estimated useful life of the assets.  Expenditures for normal repairs and maintenance are charged to expense as incurred.
	The financial condition, results of operations and cash flows of each limited partnership is consolidated in the Company’s consolidated financial statements.  The operations of the properties are not expected to contribute significantly to the Company’s income before income taxes.  However, the properties do contribute in the form of income tax credits, which lowers the Company’s effective tax rate.  Once established, the credits on each property last for ten years and are passed through from the limited partnerships to the Bank and reduces the consolidated federal tax liability of the Company.
Property and equipment	'
	Property and equipment:  Property and equipment is stated at cost less accumulated depreciation.  Depreciation is computed using primarily declining-balance methods over the estimated useful lives of 7-40 years for buildings and improvements and 3-10 years for furniture and equipment.
Deferred income taxes	'
	Deferred income taxes:  Deferred income taxes are provided under the asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and net operating loss, and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences.  Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases.  Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some or all of the deferred tax assets will not be realized.  Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.   The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained.  Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized.  Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.  Interest and penalties on unrecognized tax benefits are classified as other noninterest expense.  As of December 31, 2013, the Company had no material unrecognized tax benefits.
Goodwill	'
	Goodwill:  Goodwill represents the excess of cost over the fair value of the net assets acquired, and is not subject to amortization, but requires, at a minimum, annual impairment tests for intangibles that are determined to have an indefinite life.
Prepaid FDIC insurance	'
	Prepaid FDIC insurance:  Prepaid FDIC insurance as of December 31, 2012 represents the remaining 13-quarter FDIC premium prepayment paid by the Bank for the years of 2009 through 2012.  The balance remaining in prepaid FDIC insurance after payment of the FDIC assessments for 2012 was refunded to the Company in June 2013.  The expense for the FDIC insurance is recorded on a quarterly basis as premiums are assessed.
Other real estate	'
	Other real estate:   Other real estate represents property acquired through foreclosures and settlements of loans.  Property acquired is carried at the lower of the principal amount of the loan outstanding at the time of acquisition, plus any acquisition costs, or the estimated fair value of the property, less disposal costs.  The Bank will obtain updated appraisals to determine the estimated fair value of the property based on the type of collateral securing the loan and the date of the latest appraisal.  Subsequent write downs estimated on the basis of later valuations are charged to net loss on sale of other real estate owned and other repossessed assets.  Net expenses incurred in maintaining such properties are charged to other non-interest expense.
Derivative financial instruments	'
	Derivative financial instruments:  The Bank uses interest rate swaps as part of its interest rate risk management.  FASB Accounting Standards Codification (ASC) Topic 815 establishes accounting and reporting standards for derivative instruments and hedging activities.  The Bank records all interest rate swaps on the balance sheet at fair value.  Derivatives used to hedge the exposure to variability in expected future cash flows are considered cash flow hedges.  To qualify for hedge accounting, the Bank must comply with the detailed rules and documentation requirements at the inception of the hedge, and hedge effectiveness is assessed at inception and periodically throughout the life of the hedging relationship.
	For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivatives is initially reported in other comprehensive income and subsequently reclassified to interest income or expense when the hedged transaction affects earnings, while the ineffective portion of changes in fair value of the derivative, if any, is recognized immediately in other noninterest income.  The Bank assesses the effectiveness of each hedging relationship by comparing the cumulative changes in cash flows of the derivative hedging instruments with the cumulative changes in cash flows of the designated hedged item or transaction.  No component of the change in the fair value of the hedging instrument is excluded from the assessment of hedge effectiveness.
	The Bank does not use derivatives for trading or speculative purposes.
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 following table presents calculations of earnings per share:
		Year Ended December 31,
		2013			2012			2011
		(Amounts In Thousands, except share and per share data)
	Computation of weighted average number of basic and diluted shares:

	Earnings per share:
	Basic	$	5.51		$	5.69		$	6.02
	Diluted	$	5.5		$	5.68		$	6.01
Stock awards and options	'
	Stock awards and options:   Compensation expense for stock issued through the stock award plan is accounted for using the fair value method prescribed by FASB ASC 718, “Share-Based Payment” (“ASC 718”).  Under this method, compensation expense is measured and recognized for all stock-based awards made to employees and directors based on the fair value of each option as of the date of the grant.
Common stock held by ESOP	'
	Common stock held by ESOP:  The Company's maximum cash obligation related to these shares is classified outside stockholders' equity because the shares are not readily traded and could be put to the Company for cash.
Treasury Stock	'
	Treasury Stock:  Treasury stock is accounted for by the cost method, whereby shares of common stock reacquired are recorded at their purchase price.
Trust Department Assets	'
	Trust Department Assets:  Property held for customers in fiduciary or agency capacities is not included in the accompanying balance sheet, as such items are not assets of the Company.
Effect of New Financial Accounting Standards	'
	Effect of New Financial Accounting Standards:
	In July 2012, the FASB issued ASU 2012-02, Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment, which permits an entity to make a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset, other than goodwill, is impaired.   Under the new standard, if an entity concludes, based on an evaluation of all relevant qualitative factors, that it is not more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, it will not be required to perform the quantitative impairment test for that asset.  The standard is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted.  The adoption of this standard did not have a material impact on the consolidated financial statements.
	In February 2013, the FASB issued ASU 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income, to improve the transparency of reporting reclassification out of accumulated other comprehensive income.  The new standard is effective for reporting periods beginning after December 15, 2012, and the amendments should be prospectively applied.  The amendments do not change the current requirement for reporting net income or other comprehensive income.  The amendments require an organization to present on the face of the financial statements or in the footnotes the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income if the item reclassified is required to be reclassified to net income in its entirety in the same reporting period.  Additionally, for other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required to provide additional detail about those amounts.  The adoption of this standard did not have a material impact on the consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-01 to amend FASB ASC Topic 323, Investments – Equity Method and Joint Ventures.  The objective of this standard is to provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit.  The amendments in the standard permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met.  Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit).  The standard will be effective for the Company beginning January 1, 2015; however, early adoption is permitted.  The Company does have significant investments in such qualified affordable housing projects and is currently reviewing the provisions of this standard to determine what, if any, impacts it may have on the Company’s financial position or results of operations.

Schedule of Employee Stock Ownership Plan (ESOP)	'
	In the event a terminated plan participant desires to sell his or her shares of the Company stock, or for certain employees who elect to diversify their account balances, the Company may be required to purchase the shares from the participant at their fair value.  To the extent that shares of common stock held by the ESOP are not readily traded, a sponsor must reflect the maximum cash obligation related to those securities outside of stockholders' equity.  The Company obtains a quarterly independent appraisal of the shares of stock.  As of December 31, 2013 and 2012, the shares held by the ESOP, fair value and maximum cash obligation were as follows:
			2013				2012
	Shares held by the ESOP			394,323				438,778

Significant assumptions	'
	The fair value of each option is estimated as of the date of grant using a Black Scholes option pricing model.  The expected lives of options granted incorporate historical employee exercise behavior.  The risk-free rate for periods that coincide with the expected life of the options is based on the ten year interest rate swap rate as published by the Federal Reserve Bank on the date of issuance.  Expected volatility is based on volatility levels of the Company’s peers’ common stock as the Company’s stock has limited trading activity.  Expected dividend yield was based on historical dividend rates. Significant assumptions at date of grant include:
			2013				9-Oct-12				24-Apr-12			2011
	Risk-free interest rate			n/	a			1.77	%			2.08	%		n/	a
