PART I

Item 1.   Business

GENERAL

Hills Bancorporation (the “Company”) is a holding company principally engaged, through its subsidiary bank, in the business of banking. The Company was incorporated December 12, 1982 and all operations are conducted within the state of Iowa. The Company became owner of 100% of the outstanding stock of Hills Bank and Trust Company, Hills, Iowa (“Hills Bank and Trust” or the “Bank”) as of January 23, 1984 when stockholders of Hills Bank and Trust exchanged their shares for shares of the Company. Effective July 1, 1996, the Company formed a new subsidiary, Hills Bank, which acquired for cash all the outstanding shares of a bank in Lisbon, Iowa. Subsequently an office of Hills Bank was opened in Mount Vernon, Iowa, a community that is contiguous to Lisbon. Effective November 17, 2000, Hills Bank was merged into Hills Bank and Trust. On September 20, 1996, another subsidiary, Hills Bank Kalona, acquired cash and other assets and assumed the deposits of the Kalona, Iowa office of Boatmen’s Bank Iowa, N.A. Effective October 26, 2001, Hills Bank Kalona was merged into Hills Bank and Trust.

Through its internet website (www.hillsbank.com) the Company makes available, free of charge, by link to the internet website of the Securities and Exchange Commission (www.sec.gov), the Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, all amendment to those reports, and other filings with the Securities and Exchange Commission, as soon as reasonably practicable after they are filed or furnished.

The Bank is a full-service commercial bank extending its services to individuals, businesses, governmental units and institutional customers. The Bank is actively engaged in all areas of commercial banking, including acceptance of demand, savings and time deposits; making commercial, real estate, agricultural and consumer loans; maintaining night and safe deposit facilities; and performing collection, exchange and other banking services tailored for individual customers. The Bank administers estates, personal trusts, and pension plans and provides farm management and investment advisory and custodial services for individuals, corporations and nonprofit organizations. The Bank makes commercial and agricultural loans, real estate loans, automobile, installment and other consumer loans. In addition, the Bank earns substantial fees from originating mortgages that are sold in the secondary residential real estate market without mortgage servicing rights being retained.

The Bank has an established formal loan origination policy. In general, the loan origination policy attempts to reduce the risk of credit loss to the Bank by requiring, among other things, maintenance of minimum loan to value ratios, evidence of appropriate levels of insurance carried by borrowers and documentation of appropriate types and amounts of collateral and sources of expected payment.

The Bank’s business is not seasonal, except that loan origination fees are driven by interest rate movements and are higher in a low rate environment. As of December 31, 2006, the Company had no employees and the Bank had 327 full-time and 96 part-time employees.

COMPETITION

Competition among financial institutions in attracting and retaining deposits and making loans is intense. Traditionally, our most direct competition for deposits has come from commercial banks, savings institutions and credit unions doing business in our areas of operation. Increasingly, we have experienced additional competition for deposits from nonbanking sources, such as securities firms, insurance companies, money market mutual funds and financial services subsidiaries of commercial and manufacturing companies. Competition for loans comes primarily from other commercial banks, savings instititions, consumer finance companies, credit unions, mortgage banking companies, insurance companies and other institutional lenders. We compete primarily on the basis of products offered, customer service and price. A number of institutions with which we compete enjoy the benefits of fewer regulatory constraints and lower cost structures. Some have greater assets and capital than we do and, thus, are better able to compete on the basis of price than we are. Technological advances, which may diminish the importance of depository institutions and other financial intermediaries in the transfer of funds between parties, could make it more difficult for us to compete in the future.

Effective March 13, 2000, securities firms and insurance companies that elect to become financial holding companies were allowed to acquire banks and other financial institutions. This has increased the number of competitors and intensified the competitive environment in which the Company conducts business. The increasingly competitive environment is primarily a result of changes in regulations and changes in technology and product delivery systems. These competitive trends are likely to continue.

The Bank is in direct competition for loans and deposits and financial services with a number of other banks and credit unions in Johnson and Linn County. A comparison of the number of office locations and deposits in the two counties as of June, 2006 (Most recent date of available data from the FDIC and national credit union websites) is as follows:

	Johnson County				Linn County
	Offices		Deposits (in millions)		Offices		Deposits (in millions)
Hills Bank and Trust Company		6	$	781		5	$	232
Branches of largest competing regional bank		6		200		9		640
Largest competing independent bank		6		434		9		402
Largest competing credit union		6		399		6		338
All other bank and credit union offices		24		432		72		2,459
Total Market in County		48	$	2,246		101	$	4,071

Effective July 1, 2004, all limitations on bank office locations were repealed effectively allowing statewide branching. Since that date, banks have been allowed to establish an unlimited number of offices in any location in Iowa subject to regulatory approval. Since July 1, 2004, six new offices have been added in Johnson County and seven in Linn County, while the population base has increase by 15,000, or 4.81%, in the last two years.

THE ECONOMY

The Bank’s primary trade territory is Johnson County, Iowa. Linn County, Iowa is becoming an increasingly important market, and the Bank has five offices open in Linn County. The Bank also has two offices in Washington County, Iowa. The table that follows shows employment information as of December 31, 2006, regarding the labor force and unemployment levels in the three counties in which the Bank has office locations along with comparable data on the United States and the State of Iowa.

	Labor Force		Unemployed		Rate %
United States		155,775,000		6,849,000		4.48	%
State of Iowa		1,697,800		59,200		3.49	%
Johnson County		77,900		1,900		2.44	%
Linn County		116,100		4,500		3.88	%
Washington County		12,900		400		3.10	%

The unemployment rate for the Bank’s prime market area is favorable and the rate historically has been lower than the unemployment rates for both the United States and the State of Iowa. As discussed with the employment table of large employers in Johnson and Linn County, the University of Iowa’s impact on the local economy is very important in maintaining acceptable employment levels. The FY 2006-2007 budget for the University of Iowa is $2.3 billion with state appropriations of approximately $318 million, or about 13.9% of the total. In addition, the University of Iowa Hospitals and Clinics have a FY 2006-2007 budget of $755 million with 1.77% coming from the State of Iowa appropriation. While the State’s revenues have rebounded in the past two fiscal years, Iowa has experienced shortfalls in two of the last four budget cycles. The State’s budgetary constraints have not had a significant effect on the local economy. Johnson and Linn Counties have been one of the strongest economic areas in Iowa and have had substantial economic growth in the past ten years. The largest segment of the employed population is employed in manufacturing, management, professional or related occupations.

The economies in the counties continue to be enhanced by local Iowa colleges and the University of Iowa. In addition to providing quality employment, they enroll students who provide economic benefits to the area. The following table indicates Fall 2006 enrollment.

College	City	Enrollment
The University of Iowa	Iowa City	29,979
Coe College	Cedar Rapids	1,300
Cornell College	Mount Vernon	1,121
Kirkwood Community College	Cedar Rapids, Iowa City and Washington	15,055
Mount Mercy College	Cedar Rapids	1,482

The Bank also serves a number of smaller communities in Johnson, Linn and Washington counties that are more dependent upon the agricultural economy, which historically has been affected by commodity prices and weather. The average price per acre of farm land continues to be an important factor to consider when reviewing the local economy. The average price per acre in Iowa in 2006 was $3,204 compared to $2,914 in 2005, a 9.95% increase. The range of average land prices in Johnson, Linn and Washington counties is between $3,624 and $3,983 per acre. The three counties average increase was 12.06% in 2006. The Bank’s total agricultural loans comprise about 3.8% of the Bank’s total loans.

SUPERVISION AND REGULATION

Financial institutions and their holding companies are extensively regulated under federal and state law. As a result, the growth and earnings performance of the Company can be affected not only by management decisions and general economic conditions but also by the requirements of applicable state and federal statutes and regulations and the policies of various governmental regulatory authorities, including the Iowa Superintendent of Banking (the “Superintendent”), the Board of Governors of the Federal Reserve System (the “Federal Reserve”), the Federal Deposit Insurance Corporation (the “FDIC”), the Internal Revenue Service and state taxing authorities and the Securities and Exchange Commission (the “SEC”). The effect of applicable statutes, regulations and regulatory policies can be significant and cannot be predicted with a high degree of certainty.

Federal and state laws and regulations generally applicable to financial institutions regulate, among other things, the scope of business, investments, reserves against deposits, capital levels relative to operations, the nature and amount of collateral for loans, the establishment of branches, mergers, consolidations and dividends. The system of supervision and regulation applicable to the Company and its subsidiary Bank establishes a comprehensive framework for their respective operations and is intended primarily for the protection of the FDIC’s deposit insurance funds and the depositors, rather than the stockholders, of financial institutions. The enforcement powers available to federal and state banking regulators are substantial and include, among other things, the ability to assess civil money penalties, to issue cease-and-desist or removal orders and to initiate injunctive actions.

The following is a summary of the material elements of the regulatory framework applicable to the Company and its subsidiary Bank. It does not describe all of the statutes, regulations and regulatory policies that apply, nor does it restate all of the requirements of the statutes, regulations and regulatory policies that are described. As such, the following is qualified in its entirety by reference to the applicable statutes, regulations and regulatory policies. Any change in applicable law, regulations or regulatory policies may have a material effect on the business of the Company and its subsidiary Bank.

Regulation of the Company

General.  The Company, as the sole shareholder of the Bank, is a bank holding company. As a bank holding company, the Company is registered with, and is subject to regulation by, the Federal Reserve under the Bank Holding Company Act, as amended (the “BHCA”). According to Federal Reserve Board policy, bank/financial holding companies are expected to act as a source of financial strength to each subsidiary bank and to commit resources to support each such subsidiary. This support may be required at times when a bank/financial holding company may not be able to provide support. Under the BHCA, the Company is subject to periodic examination by the Federal Reserve. The Company is also required to file with the Federal Reserve periodic reports of the Company’s operations and such additional information regarding the Company and its subsidiaries as the Federal Reserve may require.

Investments and Activities. Under the BHCA, a bank holding company must obtain Federal Reserve approval before: (i) acquiring, directly or indirectly, ownership or control of any voting shares of another bank or bank holding company if, after the acquisition, it would own or control more than 5% of the shares of the other bank or bank holding company (unless it already owns or controls the majority of such shares), (ii) acquiring all or substantially all of the assets of another bank or (iii) merging or consolidating with another bank holding company. Subject to certain conditions (including certain deposit concentration limits established by the BHCA), the Federal Reserve may allow a bank holding company to acquire banks located in any state of the United States without regard to whether the acquisition is prohibited by the law of the state in which the target bank is located. On approving interstate acquisitions, however, the Federal Reserve is required to give effect to applicable state law limitations on the aggregate amount of deposits that may be held by the acquiring bank holding company and its insured depository institution affiliates in the state in which the target bank is located (provided that those limits do not discriminate against out-of-state depository institutions or their holding companies) and state laws which require that the target bank have been in existence for a minimum period of time (not to exceed five years) before being acquired by an out-of-state bank holding company.

Page 7 of 97

Item 1.   Business (Continued)

Investments and Activities (cont.)  The BHCA also generally prohibits the Company from acquiring direct or indirect ownership or control of more than 5% of the voting shares of any company which is not a bank and from engaging in any business other than that of banking, managing and controlling banks or furnishing services to banks and their subsidiaries. This general prohibition is subject to a number of exceptions. The principal exception allows bank holding companies to engage in, and to own shares of companies engaged in, certain businesses found by the Federal Reserve to be “so closely related to banking . . .. as to be a proper incident thereto.” Under current regulations of the Federal Reserve, the Company either directly or through non-bank subsidiaries would be permitted to engage in a variety of banking-related businesses, including the operation of a thrift, sales and consumer finance, equipment leasing, the operation of a computer service bureau (including software development) and mortgage banking and brokerage. The BHCA generally does not place territorial restrictions on the domestic activities of non-bank subsidiaries of bank holding companies.

Federal law also prohibits any person from acquiring “control” of a bank holding company without prior notice to the appropriate federal bank regulator. “Control” is defined in certain cases as the acquisition of 10% or more of the outstanding shares of a bank or a bank holding company depending on the circumstances surrounding the acquisition.

Regulatory Capital Requirements

Bank holding companies are required to maintain minimum levels of capital in accordance with Federal Reserve capital adequacy guidelines. If capital falls below minimum guideline levels, a bank holding company, among other things, may be denied approval to acquire or establish additional banks or non-bank businesses.

The Federal Reserve’s capital guidelines establish the following minimum regulatory capital requirements for bank holding companies: a risk-based requirement expressed as a percentage of total risk-weighted assets, and a leverage requirement expressed as a percentage of total assets. The risk-based requirement consists of a minimum ratio of total capital to total risk-weighted assets of 8%, at least one-half of which must be Tier 1 capital. The leverage requirement consists of a minimum ratio of Tier 1 capital to total assets of 3% for the most highly rated companies, with a minimum requirement of 4% for all others.

The risk-based and leverage standards described above are minimum requirements. Higher capital levels will be required if warranted by the particular circumstances or risk profiles of individual banking organizations. For example, the Federal Reserve’s capital guidelines contemplate that additional capital may be required to take adequate account of, among other things, interest rate risk, or the risks posed by concentration of credit, nontraditional activities or securities trading activities. Further, any banking organization experiencing or anticipating significant growth would be expected to maintain capital ratios (i.e., Tier 1 capital less all intangible assets), well above the minimum levels. Current Federal Reserve minimum requirements for a well capitalized organization experiencing significant growth are a leverage ratio of 5%, a Tier 1 risk-based capital ratio of 6% and total risk-based capital ratio of 10%. As of December 31, 2006, the Company had regulatory capital in excess of the Federal Reserve’s minimum and well-capitalized definition requirements, with a leverage ratio of 9.00%, with total Tier 1 risk-based capital ratio of 12.05% and a total risk-based capital ratio of 13.31%.

Dividends.  The Iowa Business Corporation Act (“IBCA”) allows the Company to pay dividends only out of its surplus (as defined and computed in accordance with the provision of the IBCA) or if the Company has no such surplus, out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. Additionally, the Federal Reserve has issued a policy statement with regard to the payment of cash dividends by bank holding companies. The policy statement provides that a bank holding company should not pay cash dividends which exceed its net income or which can only be funded in ways that weaken the bank holding company’s financial health, such as by borrowing. The Federal Reserve also possesses enforcement powers over bank holding companies and their non-bank subsidiaries to prevent or remedy actions that represent unsafe or unsound practices or violations of applicable statutes and regulations. Among these powers is the ability to proscribe the payment of dividends by banks and bank holding companies.

Item 1.   Business (Continued)

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

Regulation of the Bank

General. The Bank is an Iowa-chartered bank, the deposit accounts of which are insured by the FDIC’s Bank Insurance Fund (“BIF”). As an Iowa-chartered, FDIC insured bank, the Bank is subject to the examination, supervision, reporting and enforcement requirements of the Superintendent of Banking of the State of Iowa (the “Superintendent”), as the chartering authority for Iowa banks, and the FDIC, as administrator of the BIF.

Deposit Insurance.   As an FDIC-insured institution, the Bank is required to pay deposit insurance premium assessments to the FDIC. The FDIC has adopted a risk-based assessment system under which all insured depository institutions are placed into one of nine categories and assessed insurance premiums based upon their respective levels of capital and results of supervisory evaluations. Institutions classified as well-capitalized (as defined by the FDIC) and considered healthy, pay the lowest premium while institutions that are less than adequately capitalized (as defined by the FDIC) and considered of substantial supervisory concern, pay the highest premium. Risk classification of all insured institutions is made by the FDIC for each semi-annual assessment period. The Bank is currently paying the minimum assessment under the FDIC’s risk assessment system.

Capital Requirements. Among the requirements and restrictions imposed upon state banks by the Superintendent are the requirements to maintain reserves against deposits, restrictions on the nature and amount of loans, and restrictions relating to investments, opening of bank offices and other activities of state banks. Changes in the capital structure of state banks are also approved by the Superintendent. State banks must have a Tier 1 risk-based leverage ratio of 6.5% plus a fully funded loan loss reserve. In certain instances, the Superintendent may mandate higher capital, but the Superintendent has not imposed such a requirement on the Bank. In determining the Tier 1 risk-based leverage ratio, the Superintendent uses total equity capital without unrealized securities gains and the allowance for loan losses less any intangible assets. At December 31, 2006, the Tier 1 risk-based leverage ratio of the Bank was 8.95% and exceeded the ratio required by the Superintendent.

Capital adequacy for banks took on an added dimension with the establishment of a formal system of prompt corrective action under the Federal Deposit Insurance Corporation Improvement Act of 1991 (FDICIA). This system uses bank capital levels to trigger supervisory actions designed to quickly correct banking problems. Capital adequacy zones are used by the federal banking agencies to trigger these actions. The ratios and the definition of “adequate capital” are the same as those used by the agencies in their capital adequacy guidelines.

Federal law provides the federal banking regulators of the Bank with broad power to take prompt corrective action to resolve the problems of undercapitalized banking institutions. The extent of the regulators’ powers depends on whether the institution in question is “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” or “critically undercapitalized,” in each case as defined by regulation. Under prompt corrective action, banks that are inadequately capitalized face a variety of mandatory and discretionary supervisory actions. For example, “undercapitalized banks” must restrict asset growth, obtain prior approval for business expansion, and have an approved plan to restore capital. “Critically undercapitalized banks” must be placed in receivership or conservatorship within 90 days unless some other action would result in lower long-term costs to the deposit insurance fund.

Supervisory Assessments. All Iowa banks are required to pay supervisory assessments to the Superintendent to fund the Superintendent’s examination and supervision operations. Effective July 1, 2002 the Superintendent changed the method of computation of the supervisory assessment from billing for each state examination completed based on an hourly rate, to billing on an annual basis based on the assets of the bank, the expected hours needed to conduct examinations of that size bank and an additional amount if more work is required. For fiscal 2006 the assessment total was $103,772.

Item 1.   Business (Continued)

Community Investment and Consumer Protection Laws. The Community Reinvestment Act requires insured institutions to offer credit products and take other actions that respond to the credit needs of the community. Banks and other depository institutions also are subject to numerous consumer-oriented laws and regulations. These laws include the Truth in Lending Act, the Truth in Savings Act, the Real Estate Settlement Procedures Act, the Electronic Funds Transfer Act, the Equal Credit Opportunity Act and the Fair Housing Act.

Dividends.  The Iowa Banking Act provides that an Iowa bank may not pay dividends in an amount greater than its undivided profits.

The payment of dividends by any financial institution or its holding company is affected by the requirement to maintain adequate capital pursuant to applicable capital adequacy guidelines and regulations, and a financial institution generally is prohibited from paying any dividends if, following payment thereof, the institution would be undercapitalized. As described above, the Bank exceeded its minimum capital requirements under applicable guidelines as of December 31, 2006. Notwithstanding the availability of funds for dividends, however, the Superintendent may prohibit the payment of any dividends by the Bank if the Superintendent determines such payment would constitute an unsafe or unsound practice. 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 total risk-based capital to assets of 8%, retained earnings of $16,254,000 as of December 31, 2006 are available for the payment of dividends to the Company.

Insider Transactions. The Bank is subject to certain restrictions imposed by federal law on extensions of credit to the Company and its subsidiaries, on investments in the stock or other securities of the Company and its subsidiaries and the acceptance of the stock or other securities of the Company or its subsidiaries as collateral for loans. Certain limitations and reporting requirements are also placed on extensions of credit by the Bank to its directors and officers, to directors and officers of the Company and its subsidiaries, to principal stockholders of the Company, and to “related interests” of such directors, officers and principal stockholders. In addition, federal law and regulations may affect the terms upon which any person becoming a director or officer of the Company or one of its subsidiaries or a principal stockholder of the Company may obtain credit from banks with which the Bank maintains a correspondent relationship.

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

In general, the safety and soundness guidelines prescribe the goals to be achieved in each area, and each institution is responsible for establishing its own procedures to achieve those goals. If an institution fails to comply with any of the standards set forth in the guidelines, the institution’s primary federal regulator may require the institution to submit a plan for achieving and maintaining compliance. If an institution fails to submit an acceptable compliance plan, or fails in any material respect to implement a compliance plan that has been accepted by its primary federal regulator, the regulator is required to issue an order directing the institution to cure the deficiency. Until the deficiency cited in the regulator’s order is cured, the regulator may restrict the institution’s rate of growth, require the institution to increase its capital, restrict the rates the institution pays on deposits or require the institution to take any action the regulator deems appropriate under the circumstances. Noncompliance with the standards established by the safety and soundness guidelines may also constitute grounds for other enforcement action by the federal banking regulators, including cease and desist orders and civil money penalty assessments.

Branching Authority. Historically, Iowa’s intrastate branching statutes have been rather restrictive when compared with those of other states. Iowa’s intrastate branching statutes were relaxed in legislation that became effective on February 21, 2001 (the “2001 Amendment”). The 2001 Amendment allowed Iowa banks to move towards statewide branching by allowing every Iowa bank, with the approval of its primary regulator, to establish three new bank offices anywhere in Iowa during the next three years. The three offices are in addition to those offices allowed within certain restricted geographic areas under prior Iowa law. Effective July 1, 2004, the 2001 Amendment repealed all limitations on bank office location and effectively allowed statewide branching. Since that date, banks have been allowed to establish an unlimited number of offices in any location in Iowa subject only to regulatory approval.

Under the Riegle-Neal Act, both state and national banks are allowed to establish interstate branch networks through acquisitions of other banks, subject to certain conditions, including certain limitations on the aggregate amount of deposits that may be held by the surviving bank and all of its insured depository institution affiliates. The establishment of new interstate branches or the acquisition of individual branches of a bank in another state (rather than the acquisition of an out-of-state bank in its entirety) is allowed by the Riegle-Neal Act only if specifically authorized by state law. The legislation allowed individual states to “opt-out” of certain provisions of the Riegle-Neal Act by enacting appropriate legislation prior to June 1, 1997. Iowa permits interstate bank mergers, subject to certain restrictions, including a prohibition against interstate mergers involving an Iowa bank that has been in existence and continuous operation for fewer than five years.

State Bank Activities. Under federal law and FDIC regulations, FDIC insured state banks are prohibited, subject to certain exceptions, from making or retaining equity investments of a type, or in an amount, that are not permissible for a national bank. Federal law and FDIC regulations also prohibit FDIC insured state banks and their subsidiaries, subject to certain exceptions, from engaging as principal in any activity that is not permitted for a national bank or its subsidiary, respectively, unless the Bank meets, and continues to meet, its minimum regulatory capital requirements and the FDIC determines the activity would not pose a significant risk to the deposit insurance fund of which the Bank is a member. These restrictions have not had, and are not currently expected to have, a material impact on the operations of the Bank.

NONACCRUAL, PAST DUE AND RESTRUCTURED LOANS

The following table summarizes the Company’s non-accrual, past due, restructured and non-performing loans as of December 31 for each of the years presented:

	2006		2005		2004		2003		2002
	(Amounts In Thousands)
Nonaccrual loans	$	879	$	175	$	808	$	3,944	$	1,538
Accruing loans past due    90 days or more		4,983		1,910		2,313		2,296		2,516
Restructured loans		—		—		—		—		—
Non-performing (which includes non-accrual loans)		14,681		16,602		18,977		18,177		16,261

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.

Loans are placed on non-accrual status when management believes the collection of future principal and interest is not reasonably assured. The increase in non-accrual loans from December 31, 2005 to December 31, 2006 relates to three borrower relationships consisting of ten loans. Non-accrual loans represent 0.07% of total loans as of December 31, 2006 compared to 0.02% of total loans as of December 31, 2005. The non-accrual loans are considered to be impaired loans for purposes of reviewing the adequacy of the loan loss reserve. Interest income was not materially affected by this classification.

Accruing loans past due 90 days or more increased $3.1 million from 2005 to $4,983,000 as of December 31, 2006. Real estate loans make up approximately $4.2 million, or 85%, of this total. As of December 31, 2006 and 2005, loans 90 days past due and accruing were 0.38% and 0.16% of total loans, respectively.

The Company has no individual borrower or borrowers engaged in the same or similar industry exceeding 10% of total loans. The Company has no interest-bearing assets, other than loans, that meet the non-accrual, past due, restructured or potential problem loan criteria.

Non-performing loans decreased by $1.9 million from December 31, 2005 to December 31, 2006. Non-performing loans include any loan that has been placed on nonaccrual status. Non-performing 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. These loans are also considered impaired loans. The portion of non-performing loans that are real estate loans was $9.2 million at December 31, 2006 compared to $11.3 million at December 31, 2005. This decrease in non-performing loans is due primarily to an improvement in the credit quality of two commercial mortgages having an aggregate balance of approximately $3.4 million as of December 31, 2005. These two loans are no longer considered impaired. This decrease is offset by the increase in non-accrual loans noted above.

Specific allowances for losses on non-accrual and non-performing loans are established if the loan balances exceed the net present value of the relevant future cash flows or the fair value of the relevant collateral if the loan is collateral dependent.

Ratio of net charge-offs (recoveries)   during year to average loans outstanding		0.04	%		0.05	%		0.03	%		0.00	%		0.04	%

(1) For financial reporting purposes, management reviews the loan portfolio and determines the allowance for loan losses, which represents management’s judgment of the probable losses inherent in the Company’s loan portfolio. The loan loss provision is the amount necessary to adjust the allowance to the level considered appropriate by management. The adequacy of the allowance is reviewed quarterly and considers the impact of economic conditions on the borrowers’ ability to repay, loan collateral values, past collection experience, the risk characteristics of the loan portfolio and such other factors that deserve current recognition. The growth of the loan portfolio is a significant element in the determination of the provision for loan losses.

Item 1.   Business (Continued)

ALLOCATION OF THE ALLOWANCE FOR LOAN LOSSES

The Bank regularly reviews a substantial portion of the loans in the portfolio and assesses whether the loans are impaired. 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 based upon reviews of specific borrowers and provides allowances for areas that management considers are of higher credit risk (agricultural loans and constructed model real estate homes). Loans 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 percentage begins with historical loss experience factors, which are then adjusted for current economic factors.

The following table presents the allowance for loan losses on loans by type of loans and the percentage in each category to total loans as of December 31, 2006, 2005, 2004, 2003 and 2002:

	2006								2005
	Amount		% of Total Allowance			% of Loans to Total Loans			Amount		% of Total Allowance			% of Loans to Total Loans

	$	12,125		100.00	%		100.00	%

The allowance for loan losses increased $2.5 million in 2006. The increase in and changes in the allocation of the allowance were due to volume changes of loans outstanding and a deterioration in credit quality. Such deterioration is not considered by management to be a material change in credit quality. Due to the volume increase in loans outstanding of $143.1 million in 2006, the allocation increased approximately $1.3 million. The allocation for loan growth for real estate mortgage loans was $0.7 million and reflected the $77.3 million growth in this category. The real estate construction allocation also increased $0.7 million due to loan growth of $30.7 million. The commercial loan allocation increased from $2.7 million at December 31, 2005 to $3.7 million at December 31, 2006 due to loan growth in 2006 of $26.8 million.

Page 19 of 97

Item 1.   Business (Continued)

The increase in allocations based on current credit quality was $1.0 million. This increase is due in part to an increase of $19.1 million in watch loans from 2005 to 2006 resulting in an additional allocation of $0.6 million. The $19.1 million increase in watch loans is comprised of $15.1 million of commercial loans including commercial real estate, $7.3 million in construction loans, $4.2 million in residential mortgages and $1.6 million in agricultural loans. These increases were partially offset by decreases in watch loans of $8.8 million in multi-family residential loans and $0.3 million in consumer loans. Substandard loan balances were $20.5 million in 2006 and $20.6 in 2005. The increase in allocation related to substandard loans of $0.4 million resulted from the composition of loans included in this pool.

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

Item 1A. Risk Factors

The performance of our Company is subject to various risks. We consider the risks described below to be the most significant risks we face, but such risks are not the only risk factors that could affect us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition or results of operations. For a discussion of the impact of risks on our financial condition and results of operations in recent years and on forward looking statements contained in this report, reference is made to Item 7 below.

We may be adversely affected by economic conditions in the local economies in which we conduct our operations, and in the United States in general.

Unfavorable or uncertain economic and market conditions may adversely affect our business and profitability. Our business faces various material risks, including credit risk and the risk that the demand for our products and services will decrease. Foreign or domestic terrorism or geopolitical events could shock commodity and financial markets and cause an economic downturn. In an economic downturn, our credit risk and litigation expense would increase. Also, decreases in consumer confidence, real estate values, interest rates and investment returns, usually associated with a downturn, could make the types of loans we originate less profitable.

We may incur losses because of ineffective risk management processes and strategies.

We seek to monitor and control our risk exposure through a variety of financial, credit, operational, compliance and legal reporting systems. We employ risk monitoring and risk mitigation techniques, but those techniques and the judgments that accompany their application may not be adequate to deal with unexpected economic and financial events or the specifics and timing of such events. Thus, we may, in the course of our activities, incur losses despite our risk management efforts.

Our profitability and liquidity may be adversely affected by a deterioration in the credit quality of, or defaults by, third parties who owe us money or other assets.

We are exposed to the risk that third parties that owe us money or other assets will not perform their obligations. These parties may default on their obligations to us due to bankruptcy, lack of liquidity, operational failure or other reasons. Our rights against third parties may not be enforceable in all circumstances. In addition, a deterioration in the credit quality of third parties whose securities or obligations we hold could result in losses and/or adversely affect our ability to use those securities or obligations for liquidity purposes.

A failure in our operational systems or infrastructure, or those of third parties, could impair our liquidity, disrupt our business, damage our reputation and cause losses.

Shortcomings or failures in our internal processes, people or systems could lead to impairment of our liquidity, financial loss, disruption of our business, liability to our customers, regulatory interventions or damage to our reputation. Our financial, accounting, data processing or other operating systems and facilities may fail to operate properly or become disabled as a result of events that are wholly or partially beyond our control, adversely affecting our ability to process transactions. We also face the risk of operational failure or termination of any of the clearing agents, exchanges, clearing houses or other financial intermediaries we use to facilitate transactions. Any such failure or termination could adversely affect our ability to effect transactions, service our customers and manage exposure to risk.

Despite the contingency plans and facilities we have in place, our ability to conduct business may be adversely impacted by a disruption in the infrastructure that supports our business and the communities in which we are located. This may include a disruption involving electrical, communications, transportation or other services used by us or by third parties with which we conduct business. If a disruption occurs in one location and our employees in that location are unable to occupy our offices or communicate with or travel to other locations, our ability to service and interact with our customers may suffer and we may be unable to successfully implement contingency plans that depend on communication or travel.

Page 23 of 97

Item 1A. Risk Factors (Continued)

Our operations rely on the secure processing, storage and transmission of confidential and other information in our computer systems and networks. Although we take protective measures and endeavor to modify them as circumstances warrant, our computer systems, software and networks may be vulnerable to unauthorized access, computer viruses or other malicious code and other events that could have a security impact. If one or more of such events occur, this potentially could jeopardize our or our customers’ confidential and other information processed and stored in, and transmitted through, our computer systems and networks, or otherwise cause interruptions or malfunctions in our, our customers’ or third parties’ operations, which could result in significant losses or damage to our reputation. We may be required to expend significant additional resources to modify our protective measures or to investigate and remedy vulnerabilities or other exposures. In the event of such a security breach, we may be subject to litigation and financial losses that are either not insured against or not fully covered through any insurance maintained by us.

Changing interest rates may adversely affect our profits.

Our income and cash flows depend to a great extent on the difference between the interest rates earned by us on interst-earning assets such as loans and investment securities and the interest rates paid by us on interest-bearing liabilities such as deposits and borrowings. If interest rates decrease, our net interest income could be negatively affected if interest earned on interest-earning assets, such as loans, mortgage-related securities, and other investment securities, decreases more quickly than interest paid on interest-bearing liabilities, such as deposits and borrowings. This would cause our net income to go down. In addition, if interest rates decline, our loans and investments may be prepaid earlier than expected, which may also lower our income. Rising interest rates may hurt our income because they may reduce the demand for loans and the value of our investment securities. Higher interest rates could adversely affect housing and other sectors of the economy that are interest-rate sensitive. Higher interest rates could cause deterioration in the quality of our loan portfolio. Interest rates are highly sensitive to many factors that are beyond our control, including general economics conditions and monetary policies established by the Federal Reserve Board. Interest rates do and will continue to fluctuate, and we cannot predict future Federal Reserve Board actions or other factors that will cause rates to change.

We experience intense competition for loans and deposits.

Competition among financial institutions in attracting and retaining deposits and making loans is intense. Traditionally, our most direct competition for deposits has come from commercial banks, savings institutions and credit unions doing business in our areas of operation. Increasingly, we have experienced additional competition for deposits from nonbanking sources, such as securities firms, insurance companies, money market mutual funds and corporate and financial services subsidiaries of commercial and manufacturing companies. Competition for loans comes primarily from other commercial banks, savings institutions, consumer finance companies, credit unions, mortgage banking companies, insurance companies and other institutional lenders. We compete primarily on the basis of products offered, customer service and price. A number of institutions with which we compete enjoy the benefits of fewer regulatory constraints and lower cost structures. Some have greater assets and capital than we do and, thus, are better able to compete on the basis of price that we are. The increasingly competitive environment is primarily a result of changes in regulation and changes in technology and product delivery systems. These competitive trends are likely to continue.

We are subject to substantial regulation which could adversely affect our business and operations.

As a financial institution, we are subject to extensive state and federal regulation and supervision which materially affects our business. Such regulation and supervision is primarily intended for the protection of customers and deposit insurance funds. Statutes, regulations and policies to which we are subject may be changed at any time, and the interpretation and the application of those laws and regulations by our regulators is also subject to change. There can be no assurance that future changes in such statutes, regulations and policies or in their interpretation or application will not adversely affect us. We have established policies, procedures and systems designed to comply with these regulatory and operational risk requirements. However, we face complexity and costs in our compliance efforts. Adverse publicity and damage to our reputation arising from the failure or perceived failure to comply with legal, regulatory or contractual requirements could affect our ability to attract and retain customers or could result in enforcement actions, fines, penalties and lawsuits.

Page 24 of 97

Item 1A. Risk Factors (Continued)

If we do not continue to meet or exceed regulatory capital requirements and maintain our “well-capitalized” status, there could be an adverse effect on the manner in which we do business and on the confidence of our customers in us.

Under regulatory capital adequacy guidelines, we must meet guidelines that involve quantitative measures of assets, liabilities and certain off-balance sheet items. Failure to meet minimum capital requirements could have a material effect on our financial condition and could subject us to a variety of enforcement actions, as well as certain restrictions on our business. Failure to maintain the status of “well capitalized” under the regulatory framework could adversely affect the confidence that our customers have in us, which can lead to a decline in the demand for our products and affect the prices that we are able to charge for our products and services.

If we are not able to anticipate and keep pace with rapid changes in technology, or do not respond to rapid technological changes in our industry, our business can be adversely affected.

Our financial performance depends, in part, on our ability to develop and market new and innovative services, and to adopt or develop new technologies that differentiate our products or provide cost efficiencies. The risks inherent in this process include rapid technological change in the industry, our ability to access technical and other information from customers, and the significant and ongoing investments required to bring new services to market in a timely fashion at competitive prices. A further risk is the introduction by competitors of services that could replace or provide lower-cost alternatives to our products and services.

Our performance may be adversely affected if we are unable to hire and retain qualified employees.

Our performance is largely dependent on the talents and efforts of our employees. Competition in the financial services industry for qualified employees is intense. Our ability to compete effectively depends on our ability to attract new employees and to retain and motivate our existing employees.

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

Like all financial institutions, we maintain an allowance for loan losses to provide for loan defaults and non-performance. Our allowance for loan losses is based on our historical loss experience as well as an evaluation of the risks associated with its loan portfolio, including the size and composition of the loan portfolio, current economic conditions and concentrations within the portfolio. Our allowance for loan losses may not be adequate to cover actual losses, and future provisions for loan losses could materially and adversely affect our financial results.

Our reported financial results depend in part on management’s selection of accounting methods and certain assumptions and estimates.  

Our accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. Our management must exercise judgment in selecting and applying many of these accounting policies and methods so they comply with generally accepted accounting principles (GAAP) and reflect management’s judgment of the most appropriate manner to report our financial condition and results. In some cases, management must select the accounting method to apply from two or more acceptable methods, any of which might be reasonable under the circumstances yet might result in our reporting materially different results than would have been reported under a different method.

Page 25 of 97

Item 1A. Risk Factors (Continued)

Changes in accounting standards could materially impact our financial statements.  

From time to time, the Financial Accounting Standards Board (FASB) changes the financial accounting and reporting standards that govern the preparation of our financial statements. These changes can be hard to predict and can materially impact how we record and report financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retroactively, resulting in restatement of prior period financial statements.

We are exposed to risk of environmental liability when we take title to properties.  

In the course of our business, we may foreclose on and take title to real estate. As a result, we could be subject to environmental liabilities with respect to these properties. We may be held liable to a governmental entity or to third parties for property damage, personal injury, investigation and clean-up costs incurred by these parties in connection with environmental contamination or may be required to perform investigation or remediation activities that could be substantial. In addition, if we are the owner or former owner of a contaminated site, it may be subject to common law claims by third parties based on damages and costs resulting from environmental contamination emanating from the property. If we become subject to significant environmental liabilities, our financial condition and results of operations could be adversely affected.

Overview

The Company is a bank holding company engaged, through its wholly-owned subsidiary bank, in the business of commercial banking. The Company’s subsidiary is Hills Bank and Trust Company, Hills, Iowa (the“Bank”). The Bank was formed in Hills, Iowa in 1904. The Bank is a full-service commercial bank extending its services to individuals, businesses, governmental units and institutional customers primarily in the communities of Hills, Iowa City, Coralville, North Liberty, Mount Vernon, Kalona, Wellman, Cedar Rapids and Marion, Iowa. The Bank opened its Wellman location in September 2006.

The Company’s net income for 2006 was $15,559,000 compared to $15,202,000 in 2005. Diluted earnings per share were $3.39 and $3.32 for the years ended December 31, 2006 and 2005, respectively.

The Bank’s net interest income is the largest component of the Bank’s revenue, and it is a function of the average earning assets and the net interest margin percentage. Net interest margin is the ratio of tax equivalent net interest income to average earning assets. For the year ended December 31, 2006, the Bank achieved a net interest margin of 3.31% compared to 3.56% in 2005, which resulted in a decrease of $3.4 million in net interest income attributable to the reduction in the net interest margin percentage. This decrease was more than offset by an increase of $4.8 million in net interest income attributable to growth of $137.8 million in the Bank’s average earning assets. Together, these factors resulted in a $1.4 million increase in net interest income on a tax-equivalent basis.

Highlights with respect to items on the Company’s balance sheet as of December 31, 2006 included the following:

• Net loans totaling $1.283 billion.

• Loan growth in 2006 of $143.1 million and deposit growth of $71.0 million in 2006.

• Short-term borrowings increased $24.5 million and Federal Home Loan Bank borrowings increased $12.2 million.

• Stockholders’ equity increased $9.2 million in 2006, with dividends having been paid in 2006 of $3.7 million.

The return on average equity was 13.74% in 2006 compared to 14.47% in 2005. The returns for the three previous years, 2004, 2003 and 2002, were 14.34%, 15.36% and 14.05%, respectively. The total equity of the Company remains strong as of December 31, 2006 with total risk-based capital at 13.31% and Tier 1 risk-based capital at 12.05%. The minimum regulatory guidelines are 8% and 4% respectively. The Company continues to increase the dividend per share with $.81, $.75 and $.70 having been paid out in the years ended December 31, 2006, 2005 and 2004, respectively.

A detailed discussion of the financial position and results of operations follows this overview.

Critical Accounting Policies

The Company’s financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The financial information contained within these statements is, to a significant extent, financial information that is based on approximate measures of the financial effects of transactions and events that have already occurred. Based on its consideration of accounting policies that involve the most complex and subjective decisions and assessments, management has identified its most critical accounting policies to be those which are related to the allowance for loan losses. The Company’s allowance for loan loss methodology incorporates a variety of risk considerations, both quantitative and qualitative in establishing an allowance for loan loss that management believes is appropriate at each reporting date. Quantitative factors include the Company’s historical loss experience, delinquency and charge-off trends, collateral values, changes in non-performing loans, and other factors. Quantitative factors also incorporate known information about individual loans, including borrowers’ sensitivity to interest rate movements. Qualitative factors include the general economic environment in the Company’s markets, including economic conditions throughout the Midwest and in particular, the state of certain industries. Size and complexity of individual credits in relation to loan structure, existing loan policies and pace of portfolio growth are other qualitative factors that are considered in the methodology. As the Company adds new products and increases the complexity of its loan portfolio, it will enhance its methodology accordingly. This discussion of the Company’s critical accounting policies should be read in conjunction with the Company’s financial statements and the accompanying notes presented elsewhere herein, as well as other relevant portions of Management’s Discussion and Analysis of Financial Condition and Results of Operations. Although management believes the levels of the allowance as of December 31, 2006 and 2005 were adequate to absorb probable losses inherent in the loan portfolio, a decline in local economic conditions, or other factors, could result in increasing losses that cannot be reasonably predicted at this time.

               and Results of Operations  (Continued)

Total assets at December 31, 2006 increased $117.6 million, or 8.20%, from the prior year-end. Asset growth from 2004 to 2005 was $143.2 million and represented an 11.10% increase. The largest growth in assets occurred in Net Loans, which had an increase of $140.6 million and $140.3 million for the years ended December 31, 2006 and 2005, respectively. Net Loans include loans held for sale to the secondary market of $3.8 million compared to $0.7 million at the end of 2005.

Loan demand remained strong in 2006 despite the increase in interest rates. The rise in interest rates is also discussed in the net income overview that follows this financial position review. In 2006, the federal funds target rate has been raised by the Federal Reserve Open Market Committee from 4.25% to 5.25% with four increases of 0.25% each for a total of 1.00%. The upward movement of the federal funds target rate started on June 30, 2004 when the rate was increased from 1.00% to 1.25% and has increased 17 times thru December 31, 2006. The last increase was on June 29, 2006. The Federal Reserve Open Market Committee did not raise the target rate at its August, September, October or December 2006 meetings. Interest rates on loans are generally affected by these increases since interest rates for the U.S. Treasury market normally increase when the Federal Reserve Board raises the federal funds rate. In pricing of loans and deposits, the Bank considers the U.S. Treasury indexes as benchmarks in determining interest rates. Increases in interest rates may at some point materially reduce loan demand and slow the economy, but at the current interest rate levels, demand for loans remains good. The average rate index increases for 2006 compared to 2005, for the one, three and five year indexes were 1.22%, 0.79% and .64%, respectively. During this same period, the average federal funds rate increased from 3.20% in 2005 to 4.82%. These changes caused a flattening of the investment yield curve and also the large increase in short-term federal funds of 163 basis points with only a 64 point increase in the five year index.

Loans secured by real estate represent the largest increase in loan growth. These loans increased $77.3 million in 2006 and increased $108.2 million in 2005. The real estate loans for one-to-four family residential properties accounted for increases of $65.3 million in 2006 and $46.4 million in 2005. Commercial real estate loans increased a net $34.8 million for 2006 and $50.3 million for 2005. The other large increase for loans occurred for commercial loans which in 2006 increased a total of $26.8 million and $21.0 million in 2005. The overall economy in the Company’s principal place of business, Johnson and Linn Counties, remains in good condition with unemployment levels that remain low. Competition for quality loans and deposits will continue to be a challenge. In both counties, new banks and credit unions have been opened in the last few years. Between 2004 and 2006, six new banking locations were added in Johnson County and seven in Linn County. The thirteen new locations include an office of one of the state’s largest credit unions. The increased competition for both loans and deposits could result in a lower interest rate margin that could result in lower net interest income if the volume of loans and deposits does not increase to offset any such reduction in the interest margin.

Total deposits increased by $71.0 million in 2006. Short-term borrowings, which include federal funds purchased and securities sold under agreements to repurchase, increased from $34.5 million to $59.1 million. Federal funds purchased increased by $3.8 million, and repurchase agreements increased $20.8 million. Deposits increased by $79.2 million in 2005. As of June 30, 2006, Johnson County total deposits were $2.2 billion and the Company’s deposits were $781 million, which represent a 34.8% market share. At June 30, 2005, deposits were $771 million or a 37.0% market share. At $4.1 billion as of June 30, 2006, the Linn County deposit market is about twice the size of the Johnson County deposit market. The five Linn County offices of the Company had deposits of $232 million or a 5.7% share of the market. The Company’s Linn County deposits at June 30, 2005 were $172 million and represented a 4.5% market share.

               and Results of Operation  (Continued)

Investment securities decreased by $18.02 million in 2006. In 2005, investment securities decreased by $9.02 million. The investment portfolio consists of $178.1 million of securities that are stated at fair value, with any unrealized gain or loss, net of income taxes, reported as a separate component of stockholders’ equity. The securities portfolio, which includes tax exempt securities and stock of the FHLB that is required for borrowings, is used for liquidity and pledging purposes and to provide a rate of return that is acceptable to management. See Footnote 2 to the Company’s financial statements.

During 2006, the major funding sources for the growth in loans were the $71.0 million increase in deposits and additional funding from repurchase agreements, federal funds purchased and the Federal Home Loan Bank (FHLB). In 2005, the major source of funding for the growth in loans was deposit growth of $79.2 million. Total advances from the FHLB were $235.4 million and $223.2 million for 2006 and 2005, respectively. It is expected that the FHLB funding source will be used in the future when loan growth exceeds deposit increases and the interest rates on funds borrowed from the FHLB are favorable compared to other funding alternatives.

Stockholders’ equity was $118.6 million at December 31, 2006 compared to $109.5 million at December 31, 2005. The Company’s capital resources are discussed in detail in the Liquidity and Capital Resources section. Over the last five years, the Company has realized cumulative earnings of $70.7 million and paid shareholders dividends of $15.8 million, or 22.3% of earnings, while still maintaining capital ratios in excess of regulatory requirements.

Net Income Overview

Net income and diluted earnings per share for the last five years are as presented below:

Year	Net Income		% Increase (Decrease)		E.P.S.- Diluted
	(In Thousands)
2006	$	15,559	2.35	%	$	3.39
2005		15,202	7.09			3.32
2004		14,195	(0.05	)		3.11
2003		14,269	24.47			3.14
2002		11,464	13.01			2.53

Net income for 2006 increased by $0.4 million or 2.35% and diluted earnings per share increased 2.11%. A significant factor that aided in increasing the level of profit in 2006 was the growth of average earning assets. This item accounted for a $4.7 million increase in the net interest income on a tax-equivalent basis and more than offset the increased provision for loan losses of $0.9 million and the decrease in net interest margin. The increase in operating expenses of $1.5 million for the year was offset by a $1.8 million increase in other income.

Annual fluctuations in the Company’s net income continue to be driven primarily by two important factors. The first important factor is net interest margin. Net interest income of $45.3 million in 2006 was derived from the Company’s $1.423 billion of average earning assets and its net interest margin of 3.31%, compared to $1.286 billion of average earning assets and a 3.56% net interest margin in 2005. The importance of net interest margin is illustrated by the fact that a decrease in the net interest margin of only 10 basis points to 3.21% would result in a $1.4 million decrease in income before taxes. Similarly, an increase in the net interest margin of 10 basis points to 3.41% would increase income before income taxes by $1.4 million. Net interest margin decreased in 2005 to 3.56% from 3.70% in 2004.

Item 7.   Management’s Discussion and Analysis of Financial Condition
               and Results of Operation  (Continued)

The second significant factor affecting the Company’s net income is the provision for loan losses. The majority of the Company’s interest-earning assets are in loans outstanding, which amounted to $1.3 billion at the end of 2006. The growth in the loans outstanding was a principal factor in the increase in the Company’s allowance for loan losses to $17.9 million at December 31, 2006. The loan loss provision, which is the amount necessary to adjust the allowance to the level considered appropriate by management, totaled $3,011,000, $2,101,000 and $1,470,000 for 2006, 2005 and 2004, respectively. (See Note 3 to the Financial Statements.) A discussion in detail is included in the Provisions for Loan Losses section below.

Net income for 2005 was $15,202,000, or diluted earnings per share of $3.32. For 2005, diluted earnings per share increased $.21 per share. Net income for the year ended December 31, 2005, represented a $1,007,000 increase over the reported income for the same period in 2004. Net interest income, including fees, increased $2.6 million for the year ended December 31, 2005 compared to 2004. This increase in net interest income was due to an increase in average earning assets of $126.1 million in 2005. The increase in net interest income was partially offset by a $0.6 million increase in the loan loss provision. Noninterest income increased 2.12% in 2005 to $12,808,000. Noninterest expense increased from $31,965,000 in 2004 to $32,861,000 in 2005, or 2.80%.

Net Interest Income

Net interest income is the excess of the interest and fees received on interest-earning assets over the interest expense of the interest-bearing liabilities. The factors that have the greatest impact on net interest income are the volume of average earning assets and the net interest margin. The volume of average earning assets has continued to grow each year, primarily due to new loans. The net interest margin decreased in 2006 to 3.31% and this compares to 3.56% in 2005, 3.70% in 2004, 3.53% in 2003 and 3.59% in 2002. The measure is shown on a tax-equivalent basis using a rate of 35% to make the interest earned on taxable and nontaxable assets more comparable.

Net interest income on a tax-equivalent basis changed in 2006 as follows:

							Increase (Decrease)
	Change In Average Balance			Change In Average Rate
							Volume Changes			Rate Changes			Net Change
	(Amounts In Thousands)
Interest income:

Net interest margin (tax equivalent interest income    divided by average interest-earning assets)		3.31	%		3.56	%		3.70	%

Provision for Loan Losses

The provision for loan losses totaled $3,011,000, $2,101,000 and $1,470,000 for 2006, 2005 and 2004 respectively. Loan charge-offs net of recoveries were $521,000 in 2006 and $531,000 in 2005 and $265,000 in 2004. The loan loss provision is the amount necessary to adjust the allowance to the level considered appropriate by management. The provision adjustment is computed on a quarterly basis and is a result of management’s determination of the quality of the loan portfolio. The provision reflects a number of factors, including the size of the loan portfolio, loan concentrations, the impact on the borrowers’ ability to repay, loan collateral values, the level of impaired loans and loans past due ninety days or more. In addition, management considers the credit quality of the loans based on management’s review of problem and watch loans, including loans with historical higher credit risks (primarily agricultural loans).

Other factors that are considered in determining the credit quality of the Company’s loan portfolio are the vacancy rates for both residential and commercial and retail space, current equity the borrower has in the property and overall financial strength of the customer including cash flow to continue to fund loan payments. The Company also considers the state of the total economy including unemployment levels, vacancy rates of rental units and demand for commercial and retail space. In most instances, the borrowers have used in their rental projections of income at least a 10% vacancy rate. As of December 31, 2006, the unemployment levels in Johnson County and Linn County were 2.5% and 3.9%, respectively, compared to 2.7% and 4.6% in December of 2005. These levels compare favorably to the State of Iowa at 3.5% and the national unemployment level at 4.5%, which were 4.5% and 4.9%, respectively in December, 2005. The residential rental vacancy rates in 2006 in Johnson County, the largest trade area for the Company, were estimated at 10.0% in Iowa City and Coralville and 10.00% in the Cedar Rapids area. The estimated vacancy rates for both markets were 10% one year ago. The State of Iowa vacancy rate is 13.1% and the national rate is 9.9% with the Midwest rate at 12.6%. These vacancy rates one year ago were 9.4%, 9.9% and 13.4%, respectively. The Company continues to consider those vacancy rates among other factors in its current evaluation of the real estate portion of its loan portfolio.

The amount of problem or watch loans considered in the reserve computation increased by approximately $1.2 million in 2005 and by approximately $1.1 million from the end of 2003 to 2004. The increase was related to real estate mortgage loans. Overall loan balances for such loans continue to increase significantly. Some softness in the rental market place has been observed, although loan delinquency is about at the same level as the preceding year. The allowance for loan losses balance is also affected by the charge-offs and recoveries for the periods presented. For the years ended December 31, 2006, 2005 and 2004, recoveries were $1,352,000, $1,644,000, and $1,103,000, respectively; charge-offs were $1,873,000, $2,175,000 and $1,368,000 in 2006, 2005 and 2004, respectively.

Item 7.   Management’s Discussion and Analysis of Financial Condition
               And Results of Operation (Continued)

The allowance for loan losses totaled $17,850,000 at December 31, 2006 compared to $15,360,000 at December 31, 2005. The percentage of the allowance to outstanding loans was 1.37% and 1.33% at December 31, 2006 and 2005, respectively. The percentage increase was due to loan growth (fueled primarily by an increase in demand for real estate mortgage loans) and an increase in the amount of “problem” or “watch” loans as a percentage of total loans outstanding. The allowance was based on management’s consideration of a number of factors, including loan concentrations, loans with higher credit risks (primarily agriculture loans and spec real estate construction) and overall increases in Net Loans outstanding. The methodology used in 2006 is consistent with the methodology used in the prior year.

Agricultural loans totaled $49,223,000 and $43,730,000 at December 31, 2006 and 2005, respectively. The level of agriculture loans during the last five years compared to total loans has varied from a high of 4.78% in 2002 to a low of 3.78% in 2005. Management has assessed the risks for agricultural loans to be higher than other loans due to unpredictable commodity prices, the effects of weather on crops and uncertainties regarding government support programs. In particular, loans that are in the swine production segment continue to be of major concern as prices for hogs are subject to severe fluctuations.

The University of Iowa, because of its 23,600 employees and because of its total budget in Johnson County, has a tremendous impact on the economy of the Bank’s primary trade area. In 2006 and 2005, the University of Iowa helped Johnson County’s economy remain strong. The economy of the state of Iowa has recovered somewhat from recent weakness, but the University continues to suffer from budget limitations. For its fiscal year beginning July 1, 2006, the University expects continued budget constraints. The possible effects on the local economy cannot be predicted, but such budget limitations may weaken the economy in future years.

Other Income

The other income of the Company was $14,611,000 in 2006 compared to $12,808,000 in 2005. The net increase of $1,803,000 was the result of a combination of factors discussed below. In 2005, the total other income increased $266,000 from 2004. The amount of the net gain on sale of secondary market mortgage loans in each year can vary significantly. The gain was $859,000 in 2006, $1,074,000 in 2005 and $1,495,000 in 2004. The number of loans sold in 2006 was approximately 94% of the volume in 2005 and 69% of the activity experienced in 2004. Also, the fee per loan in 2005 was approximately 17% higher than the fee per loan in 2006. The volume of activity in these types of loans is directly related to the level of interest rates. Many consumers took advantage of the rates and refinanced their mortgages prior to 2004. In 2004, 2005 and 2006, rates did not drop sufficiently to make it feasible for a large volume of refinancing to occur. The servicing of the loans sold into the secondary market is not retained by the Company so these loans do not provide an ongoing stream of income.

Trust fees increased $433,000 to $3,423,000 in 2006. Trust fees increased $270,000 in 2005. As of December 31, 2006, the Bank’s Trust Department had $857 million in assets under management compared to $787 million and $694 million at December 31, 2005 and 2004, respectively. Trust fees are based on total assets under management. The trust assets that are the most volatile are those that are held in common stocks, which amount to approximately 55% of assets under management. In 2006, the market value of such common stock increased. In 2005, the market value was stable. As an example of the changes in market value, the Dow Jones Industrial Average increased over 16% in 2006 and over 3% in 2004. This average decreased less than 1% in 2005.

               And Results of Operation (Continued)

Service charges and fees increased $1,023,000 in 2006 to $6,927,000 from $5,904,000 in 2005. Such charges and fees include fees on deposit accounts and credit card processing fees on merchant accounts. Service fees on deposit accounts increased $729,000 in 2006 compared to the prior year as a result of new fee income strategies implemented in the third quarter of 2005. Other noninterest income was $2,621,000 in 2006 and $2,332,000 in 2005. Debit card interchange fees increased by $225,000 and point of sale pin interchange income increased by $134,000. Both of the increases were due to volume changes in debit card usage and are included in other noninterest income. Total other income was partially offset by $234,000 in investment securities losses in 2005. In 2006 and 2004, no securities losses were reported.

Service charges and fees increased by $650,000 from 2004 to 2005, resulting in total fees of $5,904,000 in 2005. Service fees on deposit accounts increased $196,000 in 2005 compared to 2004 due to increased volume, debit card interchange fees increased $362,000 and credit card processing fee income was up $91,000.

Other Expenses

Total other expenses were $34,364,000 and $32,861,000 for the years ended December 31, 2006 and 2005, respectively. The increase is $1,503,000 or 4.57% in 2006 and $896,000 or 2.80% in 2005. Salaries and employee benefits, the largest component of non-interest expense increased $1,379,000 in 2006, an 8.07% change. This increase includes $918,000 in direct salaries, a 7.19% increase which resulted from annual pay adjustments and the addition of twelve employees in 2006. Another component of salaries and employee benefits expense is compensation expense related to the officers’ deferred compensation plan and costs associated with restricted common stock awarded to various officers, which decreased by $199,000. This decrease is primarily the result of the change in the appraised value of the Company’s common stock. Effective June 30, 2005, as a result of the Company’s program to repurchase up to a total of 750,000 shares of the Company’s common stock, the Company began obtaining a quarterly independent appraisal of the shares of stock. Previously, the Company was obtaining an independent appraisal of the shares of stock on an annual basis for the Company’s ESOP. Due to the 2005 Stock Repurchase Program, no marketability discount was given on the new quarterly appraisals and the result was the removal by the independent appraiser of a 10% minority interest adjustment. The appraisal value of the stock based on the latest appraisal is $50.00 per share, which resulted in a per share increase of $3.50 for 2006. This compares to a $9.50 per share increase in 2005. The final appraisal for each quarter will be completed approximately forty days after each quarter end and sixty days after year-end. Medical expenses included with salaries and benefits increased to $1.5 million from $1.2 million in 2005. Beginning in 2005, the Company changed its medical plan from a self-insured plan to a full-premium plan. The actual claims paid in 2005 that were incurred but not reported prior to December 31, 2004 were under the plan administrator’s estimate by $132,000 and that reduced the 2005 expense. In addition, premiums for the medical plan increased 12% in 2006.

Occupancy expense increased $67,000 with increases of $34,000 in property taxes and $20,000 in utilities in 2006. In 2006, furniture and equipment expense included depreciation expense of $1,817,000 and $1,069,000 in equipment and software maintenance contracts. These expenses one year ago were $1,835,000 for depreciation and $983,000 for the maintenance contracts. The increase in maintenance contract expense in 2006 is due to the equipment and software purchased during the year and the related maintenance contracts.

Advertising and business development totaled $1,843,000 in 2006, a $58,000 decrease from the prior year. In 2005, as a result of the Company’s scorecard points awarded for credit card charges, the Bank incurred costs of $247,000 compared to $179,000 in 2006. The decrease of $68,000 is due to fewer points being redeemed in 2006. Also, charitable contributions decreased $57,000 to $31,000 in 2006; in 2005 charitable contributions included a $50,000 donation to the American Red Cross to assist the victims of Hurricane Katrina.

Outside services decreased $111,000 in 2006 to $4,888,000 as of December 31, 2006 compared to the same period in 2005. Outside services include professional fees, courier services and ATM fees, and processing charges for the merchant credit card program, retail credit cards and other data processing services. Professional fees decreased $242,000 from 2005 to a total of $1,472,000 for 2006. 2005 expenses included $226,000 for consulting fees for new fee income strategies. Credit card, debit card and merchant card processing increased $81,000 due to a volume increase in transactions.

Total other expenses were $31,965,000 for the year ended December 31, 2004. The increase in expenses in 2005 was $896,000. This included an increase of $441,000 in salaries and benefits, which was the direct result of salary adjustments for 2005. Medical expenses included with salaries and benefits decreased to $1.2 million from $1.3 million in 2005. Advertising and business development expenses decreased $330,000 in 2005. This change was due in part to a $160,000 decrease in the redemption of scorecard points awarded for credit card charges. In addition, there was an increase in outside services of $424,000. Outsourcing of internal audit work in 2005 accounted for $29,000 of the increase and consulting fees for new income strategy were $226,000 of the increase.

Income Taxes

Income tax expense was $6,933,000, $6,684,000 and $6,351,000 for the years ended December 31, 2006, 2005 and 2004, respectively. Income taxes as a percentage of income before income taxes were 30.82% in 2006, 30.54% in 2005 and 30.91% in 2004. The amount of tax credits were $566,000, $678,000 and $596,000 for 2006, 2005 and 2004, respectively. In 2005, the final tax credits were taken on one tax credit property. The decrease in tax credits in 2006 reflects credits for the remaining tax credit property.

Impact of Recently Issued Accounting Standards

As of January 1,2006, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2004), Share-Based Payment (FAS 123R) which requires companies to recognize in compensation expense the grant-date fair value of stock awards issued to employees and directors. The Company adopted FAS 123R using the modified prospective transition method. In accordance with the modified prospective transition method, the Company’s Consolidated Financial Statements for prior periods have not been restated to reflect the impact of FAS 123R. As a result of applying FAS l23R, the Company recognized share-based compensation expense of $ 44,000 for the year ended December 31, 2006.

As of January 1, 2006, the Company has elected to use the guidance issued by the FASB in Position FAS No. l23R-3, Transition Election Related to Accounting for the Tax Effects of Share-Based Payment Awards (“FSP FAS 123R-3”). FSP FAS 123R-3 provides a practical exception when a company transitions to the accounting requirements of FAS 123R. FAS 123R requires a company to calculate the pool of excess tax benefits available to absorb tax deficiencies recognized subsequent to adopting FAS 123R, termed the Additional Paid in Capital Pool (“APIC Pool”), assuming the company had been following the recognition provisions prescribed by FAS 123. The adoption of the FSP does not have an impact on the Company’s overall results of operations.

Impact of Recently Issued Accounting Standards (cont.)

In March 2004, the Emerging Issues Task Force (EITF) revisited EITF Issue No. 03-1, The Meaning of Other-Than-Temporary Impairment and its Application of Certain Investments. Effective with reporting periods beginning after June 15, 2004 revised EITF No. 03-1 would have required companies carrying certain types of debt and equity securities at amounts higher than the securities’ fair market values to use more detailed criteria to evaluate whether to record a loss and to disclose additional information about unrealized losses. The FASB subsequently issued a staff position deferring the effective date of the measurement and recognition provisions of the revised EITF No. 03-1 until further implementation issues could be resolved. On November 3, 2005, the FASB issued a Staff Position (FSP) that addresses the determination as to when an investment is considered impaired, whether that impairment is other than temporary, and the measurement of an impairment loss. This FSP also includes accounting considerations subsequent to the recognition of an other-than-temporary impairment and requires certain disclosures about unrealized losses that have not been recognized as other-than-temporary impairments. The guidance in the FSP shall be applied to reporting periods beginning after December 15, 2005. Adoption of the FSP did not have a material impact on the Company’s financial position and results of operations but the extent of any impact will vary due to the fact that the model, as issued, calls for many judgments and additional evidence gathering as such evidence exists at each securities valuation date.

In December 2004, the FASB issued FASB Statement No. 153, Exchanges of Nonmonetary Assets, which eliminates an exception in APB 29 for recognizing nonmonetary exchanges of similar productive assets at fair value and replaces it with an exception for recognizing exchanges of nonmonetary assets at fair value that do not have commercial substance. This Statement is effective for the Company for nonmonetary asset exchanges occurring on or after January 1, 2006. The adoption of this Statement did not have a significant effect on the Company’s financial statements.

In May 2005, the FASB issued FASB Statement No. 154, Accounting Changes and Error Corrections. Statement 154 establishes, unless impracticable, retrospective application as the required method for reporting a change in accounting principle in the absence of explicit transition requirements specific to a newly adopted accounting principle. The Company implemented the provisions of this statement as of January 1, 2006 and it did not have a significant effect on its financial statements.

In March 2006, the FASB issued FASB Statement No. 156 (“FAS 156”), Accounting for Servicing of Financial Assets and amendment of FASB Statement No. 140 (“FAS 140”), Accounting for Transfers and Extinguishment of Liabilities.  FAS 156 requires that all separately recognized servicing assets and servicing liabilities be initially measured at fair value, if practicable, and permits the Company to elect either the fair value measurement method with changes in fair value reflected in earnings or the amortization method as defined in FAS 140 for subsequent measurements. FAS 156 is effective for the Company as of January 1, 2007. The adoption of this statement will not have a significant effect on the Company’s financial statements.

In July 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes. FIN 48 requires that the Company recognize in its financial statements, the impact of a tax position if that position is more likely than not of being sustained on audit based on the technical merits of the position. The provisions of FIN 48 are effective as of January 1, 2007. The adoption of the Interpretation will not have a significant effect on the Company’s financial statements.

Impact of Recently Issued Accounting Standards (cont.)

In September 2006, the SEC issued Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (“SAB 108”). SAB 108 provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement. The SEC staff believes that registrants should quantify errors using both a balance sheet and an income statement approach and evaluate whether either approach results in quantifying a misstatement that, when all relevant quantitative and qualitative factors are considered, is material. SAB 108 is effective for years ending on or after November 15, 2006. The adoption of SAB 108 did not have any effect on the Company’s financial statements.

In September 2006, the FASB issued FASB Statement No. 157, Fair Value Measurements. The Statement provides a single definition of fair value, a framework for measuring fair value and expanded disclosures concerning fair value. Previously, different definitions of fair value were contained in various accounting pronouncements that prescribe fair value as the relevant measure of value, except FAS 123R and related interpretation and pronouncements that require or permit measurement similar to fair value but are not intended to measure fair value. The Statement is effective for financial statements issued for year beginning after November 15, 2007. The Company is currently evaluating the impact that the Statement will have on its consolidated financial statements.

Interest Rate Sensitivity and Liquidity Analysis

At December 31, 2006, the Company’s interest rate sensitivity report is as follows (amounts in thousands):

               and Results of Operation  (Continued)

The table set forth above includes the portion of the balances in interest-bearing checking, savings and money market accounts that management has estimated to mature within one year. The classifications are used because the Bank’s historical data indicates that these have been very stable deposits without much interest rate fluctuation. Historically, these accounts would not need to be adjusted upward as quickly in a period of rate increases so the interest risk exposure would be less than the re-pricing schedule indicates. The FHLB borrowings are classified based on either their due date or if they are callable on their most likely call date based on the interest rate.

Effects of Inflation

The consolidated financial statements and the accompanying notes have been prepared in accordance with generally accepted accounting principles. These principles require the measurement of financial position and operating results in terms of historical dollar amounts without considering the changes in the relative purchasing power of money over time due to inflation. The impact of inflation is reflected in the increased cost of the Company’s operations. Unlike industrial companies, nearly all of the assets and liabilities of the Company are monetary in nature. As a result, interest rates have a more significant impact in the Company’s performance than do the effects of general levels of inflation. Interest rates do not necessarily move in the same direction or to the same extent as the price of goods and services. In the current economic environment, liquidity and interest rate adjustments are features of the Company’s asset/liability management, which are important to the maintenance of acceptable performance levels. The Company attempts to maintain a balance between monetary assets and monetary liabilities, over time, to offset the potential effects of changing interest rates.

Liquidity and Capital Resources

On an unconsolidated basis, the Company had cash balances of $983,000 as of December 31, 2006. In 2006, the Company received dividends of $3,696,000 from its subsidiary Bank and used those funds to pay dividends to its stockholders of $3,696,000.

The ability of the Company to pay dividends to its shareholders is dependent upon the earnings and capital adequacy of its subsidiary Bank, which affects the Bank’s dividends to the Company. The Bank is subject to certain statutory and regulatory restrictions on the amount it may pay in dividends. In order to maintain acceptable capital ratios in the subsidiary Bank, certain of its retained earnings are not available for the payment of dividends. Retained earnings available for the payment of dividends to the Company totaled approximately $16,254,000, $13,720,000 and $13,282,000 as of December 31, 2006, 2005 and 2004, respectively. As of December 31, 2006 and 2005, stockholders’ equity, before deducting for the maximum cash obligation related to the ESOP, was $139,579,000 and $130,113,000 respectively. This measure of stockholders’ equity as a percent of total assets was 9.00% at December 31, 2006 and 9.08% at December 31, 2005. As of December 31, 2006, total equity was 7.65% of assets compared to 7.64% of assets at the prior year end.

The Company and the Bank are subject to the Federal Deposit Insurance Corporation Improvement Act of 1991, and the Bank is subject to Prompt Corrective Action Rules as determined and enforced by the Federal Reserve. These regulations establish minimum capital requirements that member banks must maintain.

As of December 31, 2006, risk-based capital standards require 8% of risk-weighted assets. At least half of that 8% must consist of Tier I core capital (common stockholders’ equity, non-cumulative perpetual preferred stock and minority interest in the equity accounts of consolidated subsidiaries), and the remainder may be Tier II supplementary capital (perpetual debt, intermediate-term preferred stock, cumulative perpetual, long-term and convertible preferred stock, and loan loss reserve up to a maximum of 1.25% of risk-weighted assets). Total risk-weighted assets are determined by weighting the assets according to their risk characteristics. Certain off-balance sheet items (such as standby letters of credit and firm loan commitments) are multiplied by “credit conversion factors” to translate them into balance sheet equivalents before assigning them risk weightings. Any bank having a capital ratio less than the 8% minimum required level must, within 60 days, submit to the Federal Reserve a plan describing the means and schedule by which the Bank shall achieve the applicable minimum capital ratios.

The Bank is an insured state bank, incorporated under the laws of the state of Iowa. As such, the Bank is subject to regulation, supervision and periodic examination by the Superintendent of Banking of the State of Iowa (the “Superintendent”). Among the requirements and restrictions imposed upon state banks by the Superintendent are the requirements to maintain reserves against deposits, restrictions on the nature and amount of loans which may be made by state banks, and restrictions relating to investments, opening of bank offices and other activities of state banks. Changes in the capital structure of state banks are also approved by the Superintendent. State banks must have a Tier 1 risk-based leverage ratio of 6.5% plus a fully funded loan loss reserve. In certain circumstances, the Superintendent may mandate higher capital, but the Superintendent has not imposed such a requirement on the Bank. In determining the Tier 1 risk-based leverage ratio, the Superintendent uses total equity capital without unrealized securities gains and the allowance for loan losses less any intangible assets. At December 31, 2006, the Tier 1 risk-based leverage ratio of the Bank was 8.95% and exceeded the ratio required by the Superintendent.

The actual amounts of risk-based capital and risk-based capital ratios as of December 31, 2006 and the minimum regulatory requirements for the Company and the Bank are presented below (amounts in thousands):

	Actual					For Capital Adequacy Purposes			To Be Well Capitalized Under Prompt Corrective Action Provisions
	Amount		Ratio			Ratio			Ratio
As of December 31, 2006:
Company:
Total risk-based capital	$	152,737		13.31	%		8.00	%		10.00	%
Tier 1 risk-based capital		138,344		12.05			4.00			6.00
Leverage ratio		138,344		9.00			3.00			5.00
Bank:
Total risk-based capital		151,983		13.25			8.00			10.00
Tier 1 risk-based capital		137,599		11.99			4.00			6.00
Leverage ratio		137,599		8.95			3.00			5.00

The Bank is classified as “well capitalized” by FDIC capital guidelines.

On a consolidated basis, 2006 cash flows from operations provided $16,454,000; proceeds of net securities sold provided $18,351,000 and net increases in deposits provided $70,995,000. These cash flows were invested in Net Loans of $140,522,000. Also, net borrowings from the FHLB increased by $12,218,000 to assist in the funding of the Bank’s increased loan demand. In addition, $2,199,000 was used to purchase property and equipment.

At December 31, 2006, the Bank had total outstanding loan commitments and unused portions of lines of credit totaling $200,786,000 (see Note 14 to the Financial Statements). Management believes that its liquidity levels are sufficient at this time, but the Bank may increase its liquidity by limiting the growth of its assets, by selling more loans in the secondary market or selling portions of loans to other banks through participation agreements. It may also obtain additional funds from the Federal Home Loan Bank (FHLB). The Bank as of December 31, 2006 can obtain an additional $206 million from the FHLB based on the current real estate mortgage loans held. In addition, the Bank has arranged $105 million of credit lines at three banks. The borrowings under these credit lines would be secured by the Bank’s investment securities.

While the Bank has off-balance sheet commitments to fund additional borrowings of customers, it does not use other off-balance-sheet financial instruments, including interest rate swaps, as part of its asset and liability management. Contractual commitments to fund loans are met from the proceeds of federal funds sold or investment securities and additional borrowings. Many of the contractual commitments to extend credit will not be funded because they represent the credit limits on credit cards and home equity lines of credits.

Item 7A.   Quantitative and Qualitative Disclosures About Market Risk

Related Party Transactions

The Bank’s primary transactions with related parties are the loan and deposit relationships it maintains with officers, directors and entities related to these individuals. The Bank makes loans to related parties under substantially the same interest rates, terms and collateral as those prevailing for comparable transactions with unrelated persons. In addition, these parties may maintain deposit account relationships with the Bank that also are on the same terms as with unrelated persons. As of December 31, 2006 and 2005, loan balances to related individuals and businesses totaled $32,638,000 and $35,797,000, respectively. Deposits from these related parties totaled $7,512,000 and $6,875,000 as of December 31, 2006 and 2005, respectively.

Commitments and Trends

The Company and the Bank have no material commitments or plans that will materially affect liquidity or capital resources. Property and equipment may be acquired in cash purchases, or they may be financed if favorable terms are available.

Market Risk Exposures

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

Item 7A.   Quantitative and Qualitative Disclosures About Market Risk (Continued)

The Bank maintains an asset/liability committee, which meets at least quarterly to review the interest rate sensitivity position and to review various strategies as to interest rate risk management. In addition, the Bank uses a simulation model to review various assumptions relating to interest rate movement. The model attempts to limit rate risk even if it appears the Bank’s asset and liability maturities are perfectly matched and a favorable interest margin is present.

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

Based on the data following, net interest income should decline with instantaneous increases in interest rates while net interest income should increase with instantaneous declines in interest rates. Generally, during periods of increasing interest rates, the Company’s interest rate sensitive liabilities would re-price faster than its interest rate sensitive assets causing a decline in the Company’s interest rate spread and margin. This would tend to reduce net interest income because the resulting increase in the Company’s cost of funds would not be immediately offset by an increase in its yield on earning assets. In times of decreasing interest rates, fixed rate assets could increase in value and the lag in re-pricing of interest rate sensitive assets could be expected to have a positive effect on the Company’s net interest income.

NOTES TO FINANCIAL STATEMENTS

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, Kalona, Wellman, Cedar Rapids and Marion, Iowa.

The Bank competes with other financial institutions and nonfinancial 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 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 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, 2006 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.

Investment securities: Held-to-maturity securities consist solely of debt securities, which the Company has the positive intent and ability to hold to maturity and are stated at amortized cost.

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 securities as of December 31, 2006 and 2005.

Stock of the Federal Home Loan Bank is carried at cost.

Premiums on debt securities are amortized over the earliest of the call date or the maturity date and discounts on debt securities are 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.

Unrealized losses judged to be other than temporary are charged to operations for both securities available for sale and securities held to maturity, and a new cost basis of the securities written down is established.

Page 60 of 97

HILLS BANCORPORATION

NOTES TO FINANCIAL STATEMENTS

Note 1.   Nature of Activities and Significant Accounting Policies (Continued)

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 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.

Loans are considered non-performing when, based on current information and events, it is probable the Bank will not be able to collect all amounts due. A non-performing loan includes any loan that has been placed on nonaccrual status. 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 non-performing 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 non-performing loans or of collateral value is reported as bad debt expense in the same manner in which impairment initially was recognized or as a reduction in the amount of bad debt expense that otherwise would be reported. Interest income on non-performing loans is recognized on the cash basis.

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.

Loan fees and origination costs are reflected in the consolidated statements of income as collected or incurred. Compared to the net deferral method, this practice had no significant effect on income in any of the years presented.

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.

Note 1.   Nature of Activities and Significant Accounting Policies (Continued)

Tax credit real estate: Tax credit real estate represents two multi-family rental properties and an assisted living rental property, all which are affordable housing projects as of December 31, 2006. 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 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 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.

Goodwill:   Goodwill represents the excess of cost over the fair value of the net assets acquired, and FASB Statement No. 142 provides for the elimination of the amortization of goodwill and other intangibles that are determined to have an indefinite life, and requires, at a minimum, annual impairment tests for intangibles that are determined to have an indefinite life. The carrying amount of goodwill as of December 31, 2006 and 2005 totaled $2,500,000.

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. Subsequent write downs estimated on the basis of later valuations, gains or losses on sales and net expenses incurred in maintaining such properties are charged to other non-interest expense. Other real estate is included in other assets and totaled $801,000 and $1,152,000 as of 2006 and 2005, respectively.

Earning 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. The following table presents calculations of earnings per share:

	Year Ended December 31,

Diluted	$	3.39		$	3.32	$	3.11

Stock awards and options: For the year ended December 31, 2006, compensation expense for stock issued through the stock award plan is accounted for using the fair value method prescribed by Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment” (FAS 123R). 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.

For the years ended December 31, 2005 and 2004, compensation expense for stock issued through the stock award plan was accounted for using the intrinsic value based method of accounting prescribed by APB Opinion No. 25, “Accounting for Stock Issues to Employees.” Under this method, compensation was measured as the difference between the estimated fair value of the stock at the date of award less the amount required to be paid for the stock. The difference, if any, was amortized straight line to expense over the vesting period of five years of service. No share-based employee compensation cost was recognized in 2005 and 2004 because all options granted under the plan had an exercise price equal to the market value of the underlying common stock on the date of grant. See Note 8 to the Financial Statements for a tabular presentation of the reconciliation between net income, basic earnings per share and diluted earnings per share as reported in the financial statements and as the information would have been reported (pro forma) if the Company has chosen to implement the fair value based method for all options.

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.

Note 1. Nature of Activities and Significant Accounting Policies (Continued)

Fair value of financial instruments: In cases where quoted market prices are not available, fair values of financial instruments are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. Certain financial instruments and all nonfinancial instruments are excluded from fair value disclosure. Accordingly, the aggregate fair value amounts presented in Note 12 to the Financial Statements do not represent the underlying value of the Company.

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

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.

Cash and due from banks and federal funds sold: The carrying amounts reported in the consolidated balance sheets for cash and short-term instruments approximate their fair values.

Investment securities: Fair values for investment securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments.

Loans receivable:  For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. 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.

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

Deposit liabilities: The fair values of deposits equal their carrying amounts, which represent the amount payable on demand.

Short-term borrowings: The carrying amounts of federal funds sold and securities sold under agreements to repurchase approximate their fair values.

Long-term borrowings: The fair values of the Bank’s long-term borrowings (other than deposits) are estimated using discounted cash flow analyses, based on the Bank’s current incremental borrowing rates for similar types of borrowing arrangements.

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

Reclassifications:  Certain prior year amounts may be reclassified to conform to the current year presentation.

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 nature of the investments with gross unrealized losses as of December 31, 2006 was as follows: U.S. government agency securities (39 positions issued and guaranteed by FNMA, FHLB, or FHLMC); and state and municipal bonds (74 issues are local issues, nonrated and 187 issues are A1 or better rated, general obligation bonds). Therefore, none of the impairments 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 cause of the impairments is due to changes in interest rates. The Company has not recognized any unrealized loss in income because management has the intent and ability to hold the securities for the foreseeable future.

The weighted average interest rate on short-term borrowings outstanding as of December 31, 2006 and 2005 was 4.40% and 3.45%, 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 government, government agency or other types of 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, 2006, $48.4 million of securities sold under repurchase agreements with a weighted average interest rate of 4.17%, maturing in 2007, were collateralized by U.S. Government agencies having an estimated fair value of $56.6 million and an amortized cost of $57.6 million.

$215 million of the borrowings were callable as of December 31, 2006, with $110 million callable in the first quarter of 2007. The advances are unlikely to be called unless rates would move significantly upwards.

The advances from the FHLB are collateralized by the Company’s investment in FHLB stock of $12,757,000 and $12,000,000 at December 31, 2006 and 2005, respectively. Additional collateral is provided by the Company’s 1-4 family mortgage loans totaling $282,455,000 at December 31, 2006 and $267,794,000 at December 31, 2005.

Note 8.   Employee Benefit Plans

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 $123,000, $115,000 and $1,038,000 for the years ended December 31, 2006, 2005 and 2004, respectively.

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 tradeable, a sponsor must reflect the maximum cash obligation related to those securities outside of stockholders’ equity as a liability. Effective June 30, 2005, as a result of the Company’s program to repurchase up to a total of 750,000 shares of the Company’s common stock, the Company began obtaining a quarterly independent appraisal of the shares of stock. Previously, the Company was obtaining an independent appraisal of the shares of stock on an annual basis for the Company’s ESOP. As of December 31, 2006 and 2005, the shares held by the ESOP, fair value and maximum cash obligation were as follows:

	2006		2005
Shares held by the ESOP		418,788		443,751
Fair value per share	$	50.00	$	46.50

Note 8.    Employee Benefit Plans (Continued)

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 profit-sharing contribution totaled $983,000, $905,000, and $0 for the years ended December 31, 2006, 2005 and 2004, respectively. The Company’s made matching contributions under its 401(k) plan of $105,000 in 2006, $98,200 in 2005 and $95,500 in 2004.

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 $2.5 million and $2.3 million at December 31, 2006 and 2005, respectively. Expense related to the deferred compensation plan was $256,000, $535,000 and $304,000 for 2006, 2005 and 2004, respectively.

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 198,000 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. Directors may exercise options immediately and officers’ rights under the plan vest over a five-year period from the date of the grant. Prior to January 1, 2006, the Company accounted for the stock options under the recognition and measurement principles of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees.

On January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (FAS 123R), which requires the measurement and recognition of compensation expense for all stock-based awards made to employees and Directors. The Company adopted FAS 123R using the modified prospective transition method. The Consolidated Financial Statements as of and for year ended December 31, 2006 reflect the impact of FAS 123R and include $44,000 of share-based compensation expense. In accordance with the modified prospective transition method, the Consolidated Financial Statements for prior periods have not been restated.

The results for the year ended December 31, 2006 are not directly comparable to the same periods in 2005 and 2004. Prior to the adoption of FAS 123R, the Company applied the existing accounting rules under APB Opinion No. 25, which provided that no compensation expense was charged for options granted at an exercise price equal to the market value of the underlying common stock on the date of the grant. If the fair value recognition provisions of FAS 123R had been applied to share-based compensation for the years ended December 31, 2005 and 2004, the Company’s pro forma net income and earnings per share would have been as follows:

	Year Ended December 31,
	2005			2004
Net income:
As reported	$	15,202		$	14,195

Note 8.   Employee Benefit Plans (Continued)

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 annual 10 year interest rate swap rate as published by the Federal Reserve Bank. Expected volatility is based on volatility levels of the Company’s peer’s common stock as the Company’s stock has limited trading activity. Expected dividend yield was based on historical dividend rates. Significant assumptions include:

	2006	2005	2004
Risk-free interest rate	—	—	4.69	%
Expected option life	—	—	7.5 years
Expected volatility	—	—	23.97	%
Expected dividends	—	—	2.08	%

Other pertinent information related to the options outstanding at December 31, 2006 is as follows:

Exercise Price		Number Outstanding	Remaining Contractual Life	Number Exercisable

		57,195		38,595

As of December 31, 2006, the outstanding options have a weighted-average exercise price of $26.79 per share and a weighted average remaining contractual term of 4.88 years. The intrinsic value of all options outstanding was $1,532,000 as of December 31, 2006.

As of December 31, 2006, there was $36,900 in unrecognized compensation cost for stock options granted under the plan. This cost is expected to be recognized over a weighted-average period of 1.16 years.

As of December 31, 2006, the vested options totaled 38,595 shares with a weighted-average exercise price of $25.22 per share and a weighted-average remaining contractual term of 4.26 years. The intrinsic value for the vested options was $973,400. The intrinsic value for all options exercised during 2006 was $139,000. The fair value of the 31,200 options vested during 2006 was $248,000.

As of December 31, 2006, 116,981 shares were available for stock options and awards. The committee is also authorized to grant awards of restricted common stock, and it authorized the issuance of 4,291 shares of common stock in 2006, 13,748 in 2005 and 222 in 2004 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, 2006, 2005 and 2004 was $149,000, $70,000 and $57,000, respectively.

Income taxes for the years ended December 31, 2006, 2005 and 2004 are summarized as follows:

	2006			2005			2004
	(Amounts In Thousands)
Current:

	$	6,933		$	6,684		$	6,351

Temporary differences between the amounts reported in the financial statements and the tax basis of assets and liabilities result in deferred taxes. No valuation allowance was required for deferred tax assets. Based upon the Company’s level of historical taxable income and anticipated future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences. Deferred tax assets and liabilities at December 31, 2006 and 2005 were as follows:

	December 31,
	2006		2005
	(Amounts In Thousands)
Deferred income tax assets:

Note 10. 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, 2006 and 2005, the Company and the Bank met all capital adequacy requirements to which they are subject.

As of December 31, 2006, 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, 2006 and 2005, with the minimum regulatory requirements for the Company and Bank are presented below (amounts in thousands):

	Actual					For Capital Adequacy Purposes			To Be Well Capitalized Under Prompt Corrective Action Provisions
	Amount		Ratio			Ratio			Ratio
As of December 31, 2006:
Company:

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 $16,254,000 as of December 31, 2006 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 $1,914,000 and $1,639,000 as of December 31, 2006 and 2005, respectively.

Note 14.   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 $22,250,000. The concentrations of credit by type of loan are set forth in Note 3 to the 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 County and Linn County, 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 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, 2006 and 2005 is as follows:

	2006		2005
	(Amounts In Thousands)
Firm loan commitments and unused portion of lines of credit:
Home equity loans	$	18,796	$	17,191
Credit card participations		28,091		24,934
Commercial, real estate and home construction		83,699		86,301
Commercial lines		70,200		61,510
Outstanding letters of credit		10,107		12,374

Page 83 of 97

HILLS BANCORPORATION

NOTES TO FINANCIAL STATEMENTS

Note 14.    Commitments and Contingencies (Continued)

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, 2006 and 2005 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, 2006 for all noncancelable leases relating to Bank premises were as follows:

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

As of the end of the period covered by this report, the Company carried out an evaluation under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective.

Management’s Report on Internal Control Over Financial Reporting

The Company’s management is responsible for establishing and maintaining an adequate system of internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Securities Exchange Act of 1934). Internal control over financial reporting of the Company includes those policies and procedures that: (1) pertain to the maintanence of records that, in reasonable detail, accurately and fairly reflect the transactions of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the Company’s financial statements. Important features of the Company’s system of internal control over financial reporting include the adoption and implementation of written policies and procedures, careful selection and training of financial management personnel, a continuing management commitment to the integrity of the system and through examinations by an internal audit function that coordinates its activities with the Company’s Independent Registered Public Accounting Firm.

All internal control systems, no matter how well designed, have inherent limitations, including the possibility of human error and the circumvention of overriding controls. Accordingly, even effective internal control can provide only reasonable assurance with respect to financial statement preparation. Further, because of changes in conditions, the effectiveness of internal control may vary over time.

The Company’s management conducted an evaluation of the effectiveness of the Company’s internal controls over financial reporting as of December 31, 2006. Management’s assessment is based on the criteria described in “Internal Control – Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, the Company’s management concluded that the Company maintained effective internal control over financial reporting as of December 31, 2006.

There was no change in the Company’s internal control over financial reporting during the most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

The Company’s independent registered public accounting firm, that audited the consolidated financial statements included in this annual report, has issued an attestation report on the Company’s internal control over financial reporting as of December 31, 2006 and management’s assessment of the internal control over financial reporting. This report appears on the following page.

KPMG LLP 2500 Ruan Center 666 Grand Avenue Des Moines, IA 50309

Report of Independent Registered Public Accounting Firm To the Board of Directors and Stockholders Hills Bancorporation: We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control Over Financial Reporting, that Hills Bancorporation (the Company) maintained effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Hills Bancorporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, management’s assessment that Hills Bancorporation maintained internal control over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Also, in our opinion, Hills Bancorporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Hills Bancorporation and subsidiaries as of December 31, 2006 and 2005, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2006, and our report dated March 9, 2007 expressed an unqualified opinion on those consolidated financial statements.
