PART I

ITEM 1. BUSINESS.

General

MidWestOne Financial Group, Inc. (“MidWestOne” or the “Company,” which is also referred to herein as “we,” “our” or “us”) is an Iowa corporation incorporated in 1983, a bank holding company under the Bank Holding Company Act of 1956 and a financial holding company under the Gramm-Leach-Bliley Act of 1999. Our principal executive offices are located at 102 South Clinton Street, Iowa City, Iowa 52240.

On March 14, 2008, we consummated a merger-of-equals transaction with the former MidWestOne Financial Group, Inc., in Oskaloosa, Iowa (“Former MidWestOne”). Prior to the merger, we operated under the name “ISB Financial Corp.” We were the surviving entity in the merger and, upon completion of the merger, changed our name from ISB Financial Corp. to MidWestOne Financial Group, Inc. and our common stock began trading on the NASDAQ Global Select Market under the symbol “MOFG.” All references herein to the “Company” and “MidWestOne” refer to the surviving organization in the merger. Following the merger, we consolidated our three bank subsidiaries, Iowa State Bank & Trust Company, First State Bank and MidWestOne Bank, into a single bank charter and renamed the surviving bank MidWestOne Bank.

We operate primarily through our bank subsidiary, MidWestOne Bank, an Iowa state non-member bank chartered in 1934 with its main office in Iowa City, Iowa, and MidWestOne Insurance Services, Inc., our wholly-owned subsidiary that operates through three agencies located in central and east-central Iowa.

As of December 31, 2012, we had total consolidated assets of $1.8 billion, total deposits of $1.4 billion and total shareholders’ equity of $173.9 million, all of which is common shareholders’ equity. For the year ended December 31, 2012, we generated net income available to common shareholders of $16.8 million, which was an increase from the net income available to common shareholders of $12.7 million and $9.3 million for the years ended December 31, 2011 and 2010, respectively. For our complete financial information as of December 31, 2012 and 2011 and for each of the years in the three-year period ended December 31, 2012, see Item 8. Financial Statements and Supplementary Data.

MidWestOne Bank operates a total of 25 branch locations, plus its specialized Home Mortgage Center, in 15 counties throughout central and east-central Iowa. MidWestOne Bank provides full service retail banking in the communities in which its branch offices are located. Deposit products offered include checking and other demand deposit accounts, NOW accounts, savings accounts, money market accounts, certificates of deposit, individual retirement accounts and other time deposits. MidWestOne Bank offers commercial and industrial, agricultural, real estate mortgage and consumer loans. Other products and services include debit cards, automated teller machines, on-line banking, mobile banking, and safe deposit boxes. The principal service consists of making loans to and accepting deposits from individuals, businesses, governmental units and institutional customers. MidWestOne Bank also has a trust and investment department through which it offers a variety of trust and investment services, including administering estates, personal trusts, conservatorships, pension and profit-sharing funds and providing property management, farm management, custodial, financial planning, investment management and retail brokerage services (the latter of which is provided through an agreement with a third-party registered broker-dealer).

Operating Strategy

Our operating strategy is based upon a sophisticated community banking model delivering a complete line of financial products and services while following five guiding principles: (1) hire and retain excellent employees; (2) take care of our customers; (3) conduct business with the utmost integrity; (4) work as one team; and (5) learn constantly so we can continually improve.

Management believes the personal and professional service offered to customers provides an appealing alternative to the “megabanks” that have resulted from large out-of-state national banks acquiring Iowa-based community banks. While we employ a community banking philosophy, we believe that our size, combined with our complete line of financial products and services, is sufficient to effectively compete in our relevant market areas. To remain price competitive, management also believes that we must grow organically, manage expenses, and remain disciplined in our asset/liability management practices.

Market Areas

Our principal offices are located in Iowa City, Iowa. The city of Iowa City is located in east-central Iowa, approximately 220 miles west of Chicago, Illinois, and approximately 115 miles east of Des Moines, Iowa. It is strategically situated approximately 60 miles west of the Mississippi River on Interstate 80 and is the home of the University of Iowa, a public university with approximately 22,000 undergraduate students and 9,500 graduate and professional students. Iowa City is the home of the University

1

of Iowa Hospitals and Clinics, a 711-bed comprehensive academic medical center and regional referral center with 1,548 staff physicians, residents, and fellows and 1,845 professional nurses. The city of Iowa City has a total population of approximately 69,000 and the Iowa City MSA has a total population of approximately 155,000. Iowa City is the fifth largest city in the state of Iowa. Based on deposit information collected by the FDIC as of June 30, 2012, the most recent date for which data is available, MidWestOne Bank had the second highest deposit market share in the Iowa City MSA at approximately 19.0%.

MidWestOne Bank operates branch offices and a loan production office in 15 counties in central and east-central Iowa. Based on deposit information collected by the FDIC as of June 30, 2012, in eight of those 15 counties, MidWestOne Bank held between 8% and 26% of the deposit market share. In another county, MidWestOne Bank held 38% of the deposit market share.

Lending Activities

General

We provide a range of commercial and retail lending services to businesses, individuals and government agencies. These credit activities include commercial, industrial and agricultural loans; real estate construction loans; commercial and residential real estate loans; and consumer loans.

We market our services to qualified lending customers. Lending officers actively solicit the business of new companies entering their market areas as well as long-standing members of the business communities in which we operate. Through professional service, competitive pricing and innovative structure, we have been successful in attracting new lending customers. We also actively pursue consumer lending opportunities. With convenient locations, advertising and customer communications, we believe that we have been successful in capitalizing on the credit needs of our market areas.

Our management emphasizes credit quality and seeks to avoid undue concentrations of loans to a single industry or based on a single class of collateral. We have established lending policies that include a number of underwriting factors to be considered in making a loan, including location, loan-to-value ratio, cash flow, interest rate and credit history of the borrower.

Real Estate Loans

Construction Loans. We offer loans both to individuals who are constructing personal residences and to real estate developers and building contractors for the acquisition of land for development and the construction of homes and commercial properties. These loans are generally in-market to known and established borrowers. Construction loans generally have a short term, such as one to two years. As of December 31, 2012, construction loans constituted approximately 8.4% of our total loan portfolio.

Mortgage Loans. We offer residential, commercial and agricultural mortgage loans. As of December 31, 2012, we had $692.9 million in combined residential, commercial and agricultural mortgage loans outstanding, which represented approximately 66.9% of our total loan portfolio.

Residential mortgage lending is a focal point for us, as residential real estate loans constituted approximately 24.4% of our total loan portfolio at December 31, 2012. Included in this category are home equity loans made to individuals. As long-term interest rates have remained at relatively low levels since 2008, many customers opted for mortgage loans that have a fixed rate with 15- or 30-year maturities. We generally retain short-term residential mortgage loans that we originate for our own portfolio, but sell most long-term loans to other parties while retaining servicing rights on the majority of such loans. We also perform loan servicing activity for third parties on participations sold. At December 31, 2012, we serviced approximately $358.4 million in mortgage loans for others. We do not offer subprime mortgage loans and do not operate a wholesale mortgage business.

We also offer mortgage loans to our commercial and agricultural customers for the acquisition of real estate used in their business, such as offices, farmland, warehouses and production facilities, and to real estate investors for the acquisition of apartment buildings, retail centers, office buildings and other commercial buildings. As of December 31, 2012, commercial and agricultural real estate mortgage loans constituted approximately 42.5% of our total loan portfolio.

Commercial and Industrial Loans

We have a strong commercial loan base. We focus on, and tailor our commercial loan programs to, small- to mid-sized businesses in our market areas. Our loan portfolio includes loans to wholesalers, manufacturers, contractors, business services companies and retailers. We provide a wide range of business loans, including lines of credit for working capital and operational

2

purposes and term loans for the acquisition of equipment. Although most loans are made on a secured basis, loans may be made on an unsecured basis where warranted by the overall financial condition of the borrower. Terms of commercial business loans generally range from one to five years.

Our commercial and industrial loans are primarily made based on the reported cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The collateral support provided by the borrower for most of these loans and the probability of repayment is based on the liquidation of the pledged collateral and enforcement of a personal guarantee, if any exists. The primary repayment risks of commercial loans are that the cash flows of the borrower may be unpredictable, and the collateral securing these loans may fluctuate in value. As of December 31, 2012, commercial and industrial loans comprised approximately 23.0% of our total loan portfolio.

Agricultural Loans

Due to the rural market areas in and around which we operate, agricultural loans are an important part of our business. Agricultural loans include loans made to finance agricultural production and other loans to farmers and farming operations. Agricultural loans comprised approximately 8.2% of our total loan portfolio at December 31, 2012.

Agricultural loans, most of which are secured by crops, livestock and machinery, are generally provided to finance capital improvements and farm operations as well as acquisitions of livestock and machinery. The ability of the borrower to repay may be affected by many factors outside of the borrower’s control, including adverse weather conditions, loss of livestock due to disease or other factors, declines in market prices for agricultural products and the impact of government regulations. The ultimate repayment of agricultural loans is dependent upon the profitable operation or management of the agricultural entity.

Our agricultural lenders work closely with our customers, including companies and individual farmers, and review the preparation of budgets and cash flow projections for the ensuing crop year. These budgets and cash flow projections are monitored closely during the year and reviewed with the customers at least once annually. We also work closely with governmental agencies to help agricultural customers obtain credit enhancement products such as loan guarantees or interest rate assistance.

Consumer Lending

Our consumer lending department provides all types of consumer loans, including personal loans (secured or unsecured) and automobile loans. Consumer loans typically have shorter terms, lower balances, higher yields and higher risks of default than one- to four-family residential real estate mortgage loans. Consumer loan collections are dependent on the borrower’s continuing financial stability, and are therefore more likely to be affected by adverse personal circumstances. As of December 31, 2012, consumer loans comprised only 1.8% of our total loan portfolio.

Loan Pool Participations

We hold in our portfolio participation interests in pools of loans that are owned and serviced by States Resources Corporation, a third-party loan servicing organization located in Omaha, Nebraska (the “Servicer”). We do not have any ownership interest in or control over the Servicer. The loans in those pools were purchased at varying discounts to their outstanding principal amount. Former MidWestOne began the program of acquiring participation interests from the Servicer in 1988 and we continued with this program following the Merger (although these loan participations have constituted a smaller percentage of our total loan portfolio than they did of Former MidWestOne’s total loan portfolio). In 2010, after extensive discussion and analysis of our current loan pool portfolio, we decided to exit this line of business as current balances pay down. This decision was based primarily on our desire to focus on our core business of providing community banking products and services. Additionally, recent loan pool yields have not provided a return reflective of the inherent risk of this investment, a situation we do not expect to change in the near future, making further investment in this class of assets unattractive.

The following discussion summarizes the accounting treatment of our loan pool participations.

A cost “basis” was assigned to each individual loan acquired on a cents per dollar basis (discounted price), which was based on the Servicer’s assessment of the recovery potential of each such loan in relation to the total discounted price paid to acquire the pool. This methodology assigned a higher basis to performing loans with greater potential collectibility and a lower basis to those loans identified as having little or no potential for collection.

Loan pool participations are shown on our balance sheet as a separate asset category; they are not included within the loan balance on our balance sheet. The original carrying value of loan pool participation interests represents the discounted price paid by us to acquire our participation interests in various loan pools purchased by the Servicer. Our investment balance with

3

respect to the participation interest is reduced as the Servicer collects principal payments on the loans and remits the proportionate share of such payments to us.

Loan pools are accounted for in accordance with the provisions of ASC Topic 310 (guidance formerly contained in Statement of Position 03-3, “Accounting for Certain Loans or Debt Securities Acquired in a Transfer”) issued by the Accounting Standards Executive Committee of the American Institute of Certified Public Accountants. According to ASC Topic 310, in order to apply the interest method of recognition to these types of loans, there must be sufficient information to reasonably estimate the amount and timing of the cash flows expected to be collected. When that is not the case, the loan is accounted for on nonaccrual status applying cash basis income recognition to the loan.

In each case, where circumstances change or new information leads the Servicer to believe that collection of the loan or recovery of the basis through collateral would be less than originally determined, the cost basis assigned to the loan is written down or written off through a charge against discount income. The Servicer and MidWestOne representatives evaluate at least quarterly the collectibility of the loans and the recovery of the underlying basis. On a quarterly basis, those loans that are determined to have a possible recovery of less than the assigned basis amount are placed on a “watch list.” The amount of basis exceeding the estimated recovery amount on the “watch list” loans is written off by a charge against discount income.

Interest income and discount on loan pool participations that we record is net of collection expenses incurred by the Servicer and net of the servicing fee and share of recovery profit paid to the Servicer. Collection expenses include salary and benefits paid by the Servicer to its employees, legal fees, costs to maintain and insure real estate owned, and other operating expenses. Under the terms of our agreement with the Servicer, the Servicer receives a servicing fee based on one percent of the gross monthly collections of principal and interest, net of collection costs. Additionally, the Servicer receives a tiered percentage share of the recovery profit in excess of our required return on investment on each individual loan pool. The Servicer’s percentage share of recovery profit is linked to a ten-tier index and ranges from zero to 27 percent depending upon the return on investment achieved. MidWestOne’s minimum required return on investment is based on the two-year treasury rate at the time a loan pool was purchased plus four percent. For every one percent increase obtained over our minimum required return, the Servicer percentage moves up one tier level. In the event that the return on a particular pool does not exceed the required return on investment, the Servicer does not receive a percentage share of the recovery profit. Discount income is added to interest income and reflected as one amount on our consolidated statements of operations.

The Servicer provides uswith monthly reports detailing collections of principal and interest, face value of loans collected and those written off, actual operating expenses incurred, remaining asset balances (both in terms of cost basis and principal amount of loans), a comparison of actual collections and expenses with target collections and budgeted expenses, and summaries of remaining collection targets. The Servicer also provides aging reports and “watch lists” for the loan pool participations. Monthly meetings are held between our representatives and representatives of the Servicer to review collection efforts and results and to discuss future plans of action. Additionally, our personnel and the Servicer’s personnel communicate on almost a daily basis to discuss various issues regarding the loan pool participations. Our representatives visit the Servicer’s operation on a regular basis, and our loan review officers perform asset reviews on a regular basis.

Our overall cost basis in the loan pool participations represents a discount from the aggregate outstanding principal amount of the loans underlying the pools. For example, as of December 31, 2012, such cost basis was $37.8 million, while the contractual outstanding principal amount of the underlying loans as of such date was approximately $105.3 million. The discounted cost basis inherently reflects the assessed collectibility of the underlying loans. We do not include any amounts related to the loan pool participations in our totals of nonperforming loans.

As part of the ongoing collection process, the Servicer may, from time to time, foreclose on real estate mortgages and acquire title to property in satisfaction of such debts. This real estate may be held by the Servicer as “real estate owned” for a period of time until it can be sold. Because our investments in loan pool participations are classified separately from our loan portfolio, we do not include the real estate owned that is held by the Servicer with the amount of any other real estate that we may hold directly as a result of our own foreclosure activities.

The underlying loans in the loan pool participations include both fixed-rate and variable-rate instruments. No amounts for interest due are reflected in the carrying value of the loan pool participations. Based on historical experience, the average period of collectibility for loans underlying our loan pool participations, many of which have exceeded contractual maturity dates, is approximately three to five years. Our management has reviewed the recoverability of the underlying loans and believes that the carrying value does not exceed the fair value of its investment in loan pool participations.

Other Products and Services

Deposit Products

We believe that we offer competitive deposit products and programs that address the needs of customers in each of the local markets that we serve. The deposit products are offered to individuals, nonprofit organizations, partnerships, small businesses, corporations and public entities. These products include noninterest bearing and interest bearing demand deposits, savings accounts, money market accounts and certificates of deposit.

Trust and Investment Services

We offer trust and investment services in our market areas to help our business and individual clients in meeting their financial goals and preserving wealth. Our services include administering estates, personal trusts, conservatorships, pension and profit-sharing funds and providing property management, farm management, investment advisory, retail securities brokerage, financial planning and custodial services. Licensed brokers (who are registered representatives of a third-party registered broker-dealer) serve selected branches and provide investment-related services including securities trading, financial planning, mutual funds sales, fixed and variable annuities and tax-exempt and conventional unit trusts.

Insurance Services

Through our insurance subsidiary, MidWestOne Insurance Services, Inc., we offer property and casualty insurance products to individuals and small businesses in the markets that we service.

Liquidity and Funding

A discussion of our liquidity and funding programs has been included in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations under “Liquidity,” and Item 7A. Quantitative and Qualitative Disclosures About Market Risk under “Liquidity Risk.”

Competition

We encounter competition in all areas of our business pursuits. To compete effectively, grow our market share, maintain flexibility and keep pace with changing economic and social conditions, we continuously refine and develop our products and services. The principal methods of competing in the financial services industry are through service, convenience and price.

The banking industry is highly competitive, and we face strong direct competition for deposits, loans, and other financial-related services. Our offices in central and east-central Iowa compete with other commercial banks, thrifts, credit unions, stockbrokers, finance divisions of auto and farm equipment companies, agricultural suppliers, and other agricultural-related lenders. Some of these competitors are local, while others are statewide, regional or nationwide. We compete for deposits principally by offering depositors a wide variety of deposit programs, convenient office locations, hours and other services, and for loan originations primarily through the interest rates and loan fees we charge, the variety of our loan products and the efficiency and quality of services we provide to borrowers, with an emphasis on building long-lasting relationships. Some of the financial institutions and financial service organizations with which we compete are not subject to the same degree of regulation as that imposed on federally insured Iowa-chartered banks. As a result, such competitors have advantages over us in providing certain services. As of June 30, 2012, there were approximately 94 other banks having 303 offices or branches operating within the 15 counties in which we have locations. Based on deposit information collected by the FDIC, as of June 30, 2012, we maintained approximately 9.1% of the bank deposits within the 15 counties in which we operate. New competitors may develop that are substantially larger and have significantly greater resources than us. Currently, major competitors in some of our markets include Wells Fargo Bank, U.S. Bank, Hills Bank & Trust, Two Rivers Bank & Trust, Marion County State Bank, and Farm Credit Services.

Employees

As of December 31, 2012, we had 390 full-time equivalent employees. We provide our employees with a comprehensive program of benefits, some of which are on a contributory basis, including comprehensive medical and dental plans, life insurance, long-term and short-term disability coverage, a 401(k) plan, and an employee stock ownership plan. None of our employees are represented by unions. Our management considers its relationship with our employees to be good.

Information on, or accessible through, our website is not part of, or incorporated by reference in, this Annual Report on Form 10-K.

Supervision and Regulation

General

Financial institutions, their holding companies and their affiliates are extensively regulated under federal and state law. As a result, our growth and earnings performance may be affected not only by management decisions and general economic conditions, but also by the requirements of federal and state statutes and by the regulations and policies of various bank regulatory authorities, including the Iowa Superintendent of Banking (the “Iowa Superintendent”), the Board of Governors of the Federal Reserve System (the “Federal Reserve”), the Federal Deposit Insurance Corporation (the “FDIC”) and the newly-created Bureau of Consumer Financial Protection (the “CFPB”). Furthermore, taxation laws administered by the Internal Revenue Service and state taxing authorities, accounting rules developed by the Financial Accounting Standards Board (the “FASB”) and securities laws administered by the Securities and Exchange Commission (the “SEC”) and state securities authorities have an impact on our business. The effect of these statutes, regulations, regulatory policies and accounting rules are significant to our operations and results, and the nature and extent of future legislative, regulatory or other changes affecting financial institutions are impossible to predict with any certainty.

Federal and state banking laws impose a comprehensive system of supervision, regulation and enforcement on the operations of financial institutions, their holding companies and affiliates that is intended primarily for the protection of the FDIC-insured deposits and depositors of banks, rather than shareholders. These federal and state laws, and the regulations of the bank regulatory authorities issued under them, affect, among other things, the scope of business, the kinds and amounts of investments banks may make, reserve requirements, capital levels relative to operations, the nature and amount of collateral for loans, the establishment of branches, the ability to merge, consolidate and acquire, dealings with insiders and affiliates and the payment of dividends. In addition, turmoil in the credit markets in recent years prompted the enactment of unprecedented legislation that allowed the U.S. Department of the Treasury (the “Treasury”) to make equity capital available to qualifying financial institutions to help restore confidence and stability in the U.S. financial markets, which imposes additional requirements on institutions in which the Treasury invests.

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

The following is a summary of the material elements of the supervisory and regulatory framework applicable to the Company and our subsidiaries. It does not describe all of the statutes, regulations and regulatory policies that apply, nor does it restate all of the requirements of those that are described. The descriptions are qualified in their entirety by reference to the particular statutory or regulatory provision.

Financial Regulatory Reform

On July 21, 2010, President Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) into law. The Dodd-Frank Act represents a sweeping reform of the supervisory and regulatory framework applicable to financial institutions and capital markets in the United States, certain aspects of which are described below in more detail. The Dodd-Frank Act creates new federal governmental entities responsible for overseeing different aspects of the U.S. financial services industry, including identifying emerging systemic risks. It also shifts certain authorities and responsibilities among federal financial institution regulators, including the supervision of holding company affiliates and the regulation of consumer financial services and products. In particular, and among other things, the Dodd-Frank Act: creates the CFPB, which is authorized to regulate providers of consumer credit, savings, payment and other consumer financial products and services; narrows the scope of federal preemption of state consumer laws enjoyed by national banks and federal savings associations and expands the authority of state attorneys

6

general to bring actions to enforce federal consumer protection legislation; imposes more stringent capital requirements on bank holding companies and subjects certain activities, including interstate mergers and acquisitions, to heightened capital conditions; significantly expands underwriting requirements applicable to loans secured by 1-4 family residential real property; restricts the interchange fees payable on debit card transactions for issuers with $10 billion in assets or greater; requires the originator of a securitized loan, or the sponsor of a securitization, to retain at least 5% of the credit risk of securitized exposures unless the underlying exposures are qualified residential mortgages or meet certain underwriting standards to be determined by regulation; creates a Financial Stability Oversight Council as part of a regulatory structure for identifying emerging systemic risks and improving interagency cooperation; provides for enhanced regulation of advisers to private funds and of the derivatives markets; enhances oversight of credit rating agencies; and prohibits banking agency requirements tied to credit ratings.

Numerous provisions of the Dodd-Frank Act are required to be implemented through rulemaking by the appropriate federal regulatory agencies. Many of the required regulations have been issued and others have been released for public comment, but there remain a number that have yet to be released in any form. Furthermore, while the reforms primarily target systemically important financial service providers, their influence is expected to filter down in varying degrees to smaller institutions over time. Management of the Company and the Bank will continue to evaluate the effect of the changes; however, in many respects, the ultimate impact of the Dodd-Frank Act will not be fully known for years, and no current assurance may be given that the Dodd-Frank Act, or any other new legislative changes, will not have a negative impact on the results of operations and financial condition of the Company and our subsidiaries.

The Increasing Regulatory Emphasis on Capital

The Company is subject to various regulatory capital requirements administered by the federal and state banking regulators noted above. Failure to meet regulatory capital requirements may result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our financial statements. Under capital adequacy guidelines and the regulatory framework for “prompt corrective action” (described below), the Company must meet specific capital guidelines that involve quantitative measures of our assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting policies. Our capital amounts and classifications are also subject to judgments by the regulators regarding qualitative components, risk weightings and other factors.

While capital has historically been one of the key measures of the financial health of both bank holding companies and depository institutions, its role is becoming fundamentally more important in the wake of the financial crisis, as the regulators have recognized that the amount and quality of capital held by banking organizations was insufficient to absorb losses during periods of severe stress. Certain provisions of the Dodd-Frank Act and Basel III, discussed below, will ultimately establish strengthened capital standards for banks and bank holding companies, will require more capital to be held in the form of common stock and will disallow certain funds from being included in capital determinations. Once fully implemented, these provisions will represent regulatory capital requirements that are meaningfully more stringent than those in place currently.

Company and Bank Required Capital Levels. Bank holding companies have historically had to comply with less stringent capital standards than their bank subsidiaries and were able to raise capital with hybrid instruments such as trust preferred securities. The Dodd-Frank Act mandated the Federal Reserve to establish minimum capital levels for bank holding companies on a consolidated basis that are as stringent as those required for insured depository institutions. As a consequence, over a phase-in period of three years, the components of holding company permanent capital known as “Tier 1 capital” are being restricted to capital instruments that are considered to be Tier 1 capital for insured depository institutions. A result of this change is that the proceeds of trust preferred securities are being excluded from Tier 1 capital unless such securities were issued prior to May 19, 2010 by bank holding companies with less than $15 billion of assets. Because the Company has assets of less than $15 billion, it is able to maintain its trust preferred proceeds as Tier 1 capital but will have to comply with new capital mandates in other respects, and will not be able to raise Tier 1 capital in the future through the issuance of trust preferred securities. In addition, the Basel III proposal, discussed below, includes a phase-out of trust preferred securities for all bank holding companies, including the Company.

Under current federal regulations, the Bank is subject to, and, after a phase-in period, the Company will be subject to, the following minimum capital standards:

• a leverage requirement, consisting of a minimum ratio of Tier 1 capital to total assets of 3% for the most highly-rated banks with a minimum requirement of at least 4% for all others; and

• a risk-based capital requirement, consisting of a minimum ratio of total capital to total risk-weighted assets of 8% and a minimum ratio of Tier 1 capital to total risk-weighted assets of 4%. For this purpose, “Tier 1 capital” consists primarily of common stock, noncumulative perpetual preferred stock and related surplus less intangible assets (other than certain loan servicing rights and purchased credit card relationships). Total capital consists primarily of Tier 1

7

capital plus “Tier 2 capital,” which includes other non-permanent capital items, such as certain other debt and equity instruments that do not qualify as Tier 1 capital, and a portion of the Bank's allowance for loan and lease losses.

The capital standards described above are minimum requirements. Federal law and regulations provide various incentives for banking organizations to maintain regulatory capital at levels in excess of minimum regulatory requirements. For example, a banking organization that is “well-capitalized” may: (i) qualify for exemptions from prior notice or application requirements otherwise applicable to certain types of activities; (ii) qualify for expedited processing of other required notices or applications; and (iii) accept brokered deposits. Under the capital regulations of the Federal Reserve, in order to be “well-capitalized,” a banking organization must maintain a ratio of total capital to total risk-weighted assets of 10% or greater, a ratio of Tier 1 capital to total risk-weighted assets of 6% or greater and a ratio of Tier 1 capital to total assets of 5% or greater. The Federal Reserve's guidelines also provide that bank holding companies experiencing internal growth or making acquisitions will be expected to maintain strong capital positions substantially above the minimum supervisory levels without significant reliance on intangible assets. Furthermore, the guidelines indicate that the Federal Reserve will continue to consider a “tangible Tier 1 leverage ratio” (deducting all intangibles) in evaluating proposals for expansion or to engage in new activity.

Higher capital levels may also be required if warranted by the particular circumstances or risk profiles of individual banking organizations. For example, the Federal Reserve's capital guidelines contemplate that additional capital may be required to take adequate account of, among other things, interest rate risk, or the risks posed by concentrations of credit, nontraditional activities or securities trading activities. Further, any banking organization experiencing or anticipating significant growth would be expected to maintain capital ratios, including tangible capital positions (i.e., Tier 1 capital less all intangible assets), well above the minimum levels.

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

As of December 31, 2012: (i) the Bank was not subject to a directive from the FDIC to increase capital to an amount in excess of the minimum regulatory capital requirements; (ii) the Bank exceeded its minimum regulatory capital requirements under FDIC capital adequacy guidelines; and (iii) the Bank was “well-capitalized,” as defined by FDIC regulations. As of December 31, 2012, the Company had regulatory capital in excess of the Federal Reserve’s requirements and met the Dodd-Frank Act capital requirements.

Basel III. The current risk-based capital guidelines described above, which apply to the Bank and are being phased in for the Company, are based upon the 1988 capital accord known as “Basel I” adopted by the international Basel Committee on Banking Supervision, a committee of central banks and bank supervisors, as implemented by the U.S. federal banking regulators on an interagency basis. In 2008, the banking agencies collaboratively began to phase-in capital standards based on a second capital accord, referred to as “Basel II,” for large or “core” international banks (generally defined for U.S. purposes as having total assets of $250 billion or more, or consolidated foreign exposures of $10 billion or more). Basel II emphasized internal assessment of credit, market and operational risk, as well as supervisory assessment and market discipline in determining minimum capital requirements.

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

• a new required ratio of minimum common equity equal to 4.5% of risk-weighted assets;

• an increase in the minimum required amount of Tier 1 capital from the current level of 4% of total assets to 6% of risk-weighted assets; and

• a continuation of the current minimum required amount of total capital at 8% of risk-weighted assets.

8

In addition, institutions that seek the freedom to make capital distributions (including for dividends and repurchases of stock) and pay discretionary bonuses to executive officers without restriction must also maintain 2.5% in common equity attributable to a capital conservation buffer to be phased in over three years. The purpose of the conservation buffer is to ensure that banks maintain a buffer of capital that can be used to absorb losses during periods of financial and economic stress. Factoring in the conservation buffer increases the ratios depicted above to 7% for common equity, 8.5% for Tier 1 capital and 10.5% for total capital.

On June 12, 2012, the federal banking regulators (the Office of the Comptroller of the Currency, the Federal Reserve and the FDIC) (the “Agencies”) formally proposed for comment, in three separate but related proposals, rules to implement Basel III in the United States. The proposals are: (i) the “Basel III Proposal,” which applies the Basel III capital framework to almost all U.S. banking organizations; (ii) the “Standardized Approach Proposal,” which applies certain elements of the Basel II standardized approach for credit risk weightings to almost all U.S. banking organizations; and (iii) the “Advanced Approaches Proposal,” which applies changes made to Basel II and Basel III in the past few years to large U.S. banking organizations subject to the advanced Basel II capital framework. The comment period for these notices of proposed rulemaking ended October 22, 2012.

The Basel III Proposal and the Standardized Approach Proposal are expected to have a direct impact on the Company and the Bank. The Basel III Proposal is applicable to all U.S. banks that are subject to minimum capital requirements, including federal and state banks, as well as to bank and savings and loan holding companies other than “small bank holding companies” (generally bank holding companies with consolidated assets of less than $500 million). There will be separate phase-in/phase-out periods for: (i) minimum capital ratios; (ii) regulatory capital adjustments and deductions; (iii) nonqualifying capital instruments; (iv) capital conservation and countercyclical capital buffers; (v) a supplemental leverage ratio for advanced approaches banks; and (vi) changes to the FDIC's prompt corrective action rules.

The criteria in the U.S. proposal for common equity and additional Tier 1 capital instruments, as well as Tier 2 capital instruments, are broadly consistent with the Basel III criteria. A number of instruments that now qualify as Tier 1 capital will not qualify, or their qualification will change, if the Basel III Proposal becomes final. For example, cumulative preferred stock and certain hybrid capital instruments, including trust preferred securities, which the Company may retain under the Dodd-Frank Act, will no longer qualify as Tier 1 capital of any kind. Noncumulative perpetual preferred stock, which now qualifies as simple Tier 1 capital, would not qualify as common equity Tier 1 capital, but would qualify as additional Tier 1 capital.

In addition to the changes in capital requirements included within the Basel III Proposal, the Standardized Approach Proposal revises a large number of the risk weightings (or their methodologies) for bank assets that are used to determine the capital ratios. For nearly every class of assets, the proposal requires a more complex, detailed and calibrated assessment of credit risk and calculation of risk weightings. For example, under the current risk-weighting rules, residential mortgages have a risk weighting of 50%. Under the proposed new rules, two categories of residential mortgage lending would be created: (i) traditional lending would be category 1, where the risk weightings range from 35 to 100%; and (ii) nontraditional loans would fall within category 2, where the risk weightings would range from 50 to 150%. There is concern in the U.S. that the proposed methodology for risk weighting residential mortgage exposures and the higher risk weightings for certain types of mortgage products will increase costs to consumers and reduce their access to mortgage credit.

In addition, there is significant concern noted by the financial industry in connection with the Basel III rulemaking as to the proposed treatment of accumulated other comprehensive income (“AOCI”). The proposed treatment of AOCI would require unrealized gains and losses on available-for-sale securities to flow through to regulatory capital as opposed to the current treatment, which neutralizes such effects. There is concern that this treatment would introduce capital volatility, due not only to credit risk but also to interest rate risk, and affect the composition of firms' securities holdings.

While the Basel III accord called for national jurisdictions to implement the new requirements beginning January 1, 2013, in light of the volume of comments received by the Agencies and the concerns expressed above, the Agencies have indicated that the commencement date for the proposed Basel III rules has been delayed and it is unclear when the Basel III regime, as it may be implemented by final rules, will become effective in the United States.

The Company

General. As the sole shareholder of the Bank, we are a bank holding company. As a bank holding company, we are registered with, and are subject to regulation by, the Federal Reserve under the Bank Holding Company Act of 1956, as amended (the “BHCA”). In accordance with Federal Reserve policy, and as now codified by the Dodd-Frank Act, we are legally obligated to act as a source of financial strength to the Bank and to commit resources to support the Bank in circumstances where we might not otherwise do so. Under the BHCA, we are subject to periodic examination by the Federal Reserve. We are also required to

9

file with the Federal Reserve periodic reports of our operations and such additional information regarding the Company and our subsidiaries as the Federal Reserve may require.

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

The BHCA generally prohibits us from acquiring direct or indirect ownership or control of more than 5% of the voting shares of any company that is not a bank and from engaging in any business other than that of banking, managing and controlling banks or furnishing services to banks and their subsidiaries. This general prohibition is subject to a number of exceptions. The principal exception allows bank holding companies to engage in, and to own shares of companies engaged in, certain businesses found by the Federal Reserve prior to November 11, 1999 to be “so closely related to banking . . . as to be a proper incident thereto.” This authority would permit us to engage in a variety of banking-related businesses, including the ownership and operation of a thrift, or any entity engaged in 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 nonbank subsidiaries of bank holding companies.

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

Financial Holding Company Regulation. Additionally, bank holding companies that meet certain eligibility requirements prescribed by the BHCA and elect to operate as financial holding companies may engage in, or own shares in companies engaged in, a wider range of nonbanking activities, including securities and insurance underwriting and sales, merchant banking and any other activity that the Federal Reserve, in consultation with the Secretary of the Treasury, determines by regulation or order is financial in nature, incidental to any such financial activity or complementary to any such financial activity and does not pose a substantial risk to the safety or soundness of depository institutions or the financial system generally. We have elected (and the Federal Reserve has accepted our election) to operate as a financial holding company.

In order to become and maintain our status as a financial holding company, the Company and the Bank must be well-capitalized, well-managed, and have a least a satisfactory Community Reinvestment Act (“CRA”) rating. If the Federal Reserve determines that a financial holding company is not well-capitalized or well-managed, the company has a period of time in which to achieve compliance, but during the period of noncompliance, the Federal Reserve may place any limitations on the company it believes to be appropriate. Furthermore, if the Federal Reserve determines that a financial holding company's subsidiary bank has not received a satisfactory CRA rating, the company will not be able to commence any new financial activities or acquire a company that engages in such activities.

Capital Requirements. Bank holding companies are required to maintain minimum levels of capital in accordance with Federal Reserve capital adequacy guidelines, as affected by the Dodd-Frank Act and Basel III. For a discussion of capital requirements, see “-The Increasing Regulatory Emphasis on Capital” above. If capital levels fall below the minimum required levels, a bank holding company, among other things, may be denied approval to acquire or establish additional banks or nonbank businesses.

U.S. Government Investment in Bank Holding Companies.Events in the U.S. and global financial markets in 2008 and 2009, including the deterioration of the worldwide credit markets, created significant challenges for financial institutions throughout the country. In response to this crisis affecting the U.S. banking system and financial markets, on October 3, 2008, the U.S. Congress passed, and the President signed into law, the Emergency Economic Stabilization Act of 2008 (the “EESA”). The EESA authorized the Secretary of the Treasury to implement various temporary emergency programs designed to strengthen the capital positions

10

of financial institutions and stimulate the availability of credit within the U.S. financial system. Financial institutions participating in certain of the programs established under the EESA are required to adopt the Treasury's standards for executive compensation and corporate governance.

On October 14, 2008, the Treasury announced that it would provide Tier 1 capital (in the form of perpetual preferred stock) to eligible financial institutions. This program, known as the TARP Capital Purchase Program (the “CPP”), allocated $250 billion from the $700 billion authorized by the EESA to the Treasury for the purchase of senior preferred shares from qualifying financial institutions (the “CPP Preferred Stock”). Under the program, eligible institutions were able to sell equity interests to the Treasury in amounts equal to between 1% and 3% of the institution's risk-weighted assets. The CPP Preferred Stock is non-voting and pays dividends at the rate of 5% per annum for the first five years and thereafter at a rate of 9% per annum. In conjunction with the purchase of the CPP Preferred Stock, the Treasury received warrants to purchase common stock from the participating public institutions with an aggregate market price equal to 15% of the preferred stock investment. Participating financial institutions were required to adopt the Treasury's standards for executive compensation and corporate governance for the period during which the Treasury holds equity issued under the CPP.

Pursuant to the CPP, on February 6, 2009, we entered into a Letter Agreement with the Treasury, pursuant to which we issued: (i) 16,000 shares of CPP Preferred Stock (designated as “Fixed Rate Cumulative Perpetual Preferred Stock, Series A”); and (ii) a warrant to purchase 198,675 shares of our common stock, par value $1.00 per share, for an aggregate purchase price of $16.0 million in cash.

CPP Repurchase. As approved by the Federal Reserve Board, the Treasury and our other banking regulators, on July 6, 2011, we redeemed from the Treasury all 16,000 outstanding shares of our CPP Preferred Stock, for a redemption price of approximately $16.1 million, including accrued but unpaid dividends to the date of redemption. On July 27, 2011, we also repurchased the warrant issued to the Treasury for an aggregate purchase price of $1.0 million. As a result of our redemption of the CPP Preferred Stock, we are no longer subject to the limits on executive compensation and other restrictions stipulated under the CPP.

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

As a general matter, the Federal Reserve indicates that the board of directors of a bank holding company should eliminate, defer or significantly reduce the dividends if: (i) the company's net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; (ii) the prospective rate of earnings retention is inconsistent with the company's capital needs and overall current and prospective financial condition; or (iii) the company will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios. The Federal Reserve also possesses enforcement powers over bank holding companies and their nonbank 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.

Federal Securities Regulation. Our common stock is registered with the SEC under the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Consequently, we are subject to the information, proxy solicitation, insider trading and other restrictions and requirements of the SEC under the Exchange Act.

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

11

The Bank

General. The Bank is an Iowa-chartered bank, the deposit accounts of which are insured by the FDIC's Deposit Insurance Fund (the “DIF”) to the maximum extent provided under federal law and FDIC regulations. As an Iowa-chartered bank, the Bank is subject to the examination, supervision, reporting and enforcement requirements of the Iowa Superintendent, the chartering authority for Iowa banks, and the FDIC, designated by federal law as the primary federal regulator of state-chartered, FDIC-insured banks that, like the Bank, are not members of the Federal Reserve System (“non-member banks”).

Deposit Insurance. As an FDIC-insured institution, the Bank is required to pay deposit insurance premium assessments to the FDIC. The FDIC has adopted a risk-based assessment system whereby FDIC-insured depository institutions pay insurance premiums at rates based on their risk classification. An institution's risk classification is assigned based on its capital levels and the level of supervisory concern the institution poses to the regulators.

On November 12, 2009, the FDIC adopted a final rule that required insured depository institutions to prepay on December 30, 2009, their estimated quarterly risk-based assessments for the fourth quarter of 2009 and for all of 2010, 2011, and 2012. As such, on December 31, 2009, the Bank prepaid the FDIC its assessments based on its: (i) actual September 30, 2009 assessment base, increased quarterly by a 5% annual growth rate through the fourth quarter of 2012; and (ii) total base assessment rate in effect on September 30, 2009, increased by an annualized three basis points beginning in 2011. The FDIC began to offset prepaid assessments on March 30, 2010, representing payment of the regular quarterly risk-based deposit insurance assessment for the fourth quarter of 2009. Any prepaid assessment not exhausted after collection of the amount due on June 30, 2013, will be returned to the institution.

Amendments to the Federal Deposit Insurance Act also revise the assessment base against which an insured depository institution's deposit insurance premiums paid to the DIF will be calculated.  Under the amendments, the assessment base will no longer be the institution's deposit base, but rather its average consolidated total assets less its average tangible equity.  This may shift the burden of deposit insurance premiums toward those large depository institutions that rely on funding sources other than U.S. deposits.  Additionally, the Dodd-Frank Act makes changes to the minimum designated reserve ratio of the DIF, increasing the minimum from 1.15% to 1.35% of the estimated amount of total insured deposits, and eliminating the requirement that the FDIC pay dividends to depository institutions when the reserve ratio exceeds certain thresholds.  The FDIC is given until September 3, 2020 to meet the 1.35% reserve ratio target. Several of these provisions could increase the Bank's FDIC deposit insurance premiums. 

The Dodd-Frank Act permanently increases the maximum amount of deposit insurance for banks, savings institutions and credit unions to $250,000 per insured depositor, retroactive to January 1, 2009. Although the legislation provided that non-interest-bearing transaction accounts had unlimited deposit insurance coverage through December 31, 2012.

FICO Assessments.The Financing Corporation (“FICO”) is a mixed-ownership governmental corporation chartered by the former Federal Home Loan Bank Board pursuant to the Competitive Equality Banking Act of 1987 to function as a financing vehicle for the recapitalization of the former Federal Savings and Loan Insurance Corporation. FICO issued 30-year non-callable bonds of approximately $8.1 billion that mature in 2017 through 2019. FICO's authority to issue bonds ended on December 12, 1991. Since 1996, federal legislation has required that all FDIC-insured depository institutions pay assessments to cover interest payments on FICO's outstanding obligations. These FICO assessments are in addition to amounts assessed by the FDIC for deposit insurance. During the year ended December 31, 2012, the FICO assessment rate was approximately 0.0066%, which reflects the change from an assessment base computed on deposits to an assessment base computed on assets as required by the Dodd-Frank Act.

Supervisory Assessments. All Iowa banks are required to pay supervisory assessments to the Iowa Superintendent to fund the operations of that agency. The amount of the assessment is calculated on the basis of the Bank's total assets. During the year ended December 31, 2012, the Bank paid supervisory assessments to the Iowa Superintendent totaling $144,000.

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

Dividend Payments. The primary source of funds for the Company is dividends from the Bank. Under the Iowa Banking Act, Iowa-chartered banks generally may pay dividends only out of undivided profits. In addition, the Iowa Superintendent may restrict the declaration or payment of a dividend by an Iowa-chartered bank, such as the Bank.

The payment of dividends by any financial institution 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

12

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, 2012. As of December 31, 2012, approximately $15.7 million was available to be paid as dividends by the Bank. Notwithstanding the availability of funds for dividends, however, the FDIC may prohibit the payment of any dividends by the Bank if the FDIC determines such payment would constitute an unsafe or unsound practice.

Insider Transactions. The Bank is subject to certain restrictions imposed by federal law on “covered transactions” between the Bank and its affiliates. The Company is an affiliate of the Bank for purposes of these restrictions, and covered transactions subject to the restrictions include extensions of credit to the Company, investments in our stock or other securities and the acceptance of our stock or other securities as collateral for loans made by the Bank. The Dodd-Frank Act enhances the requirements for certain transactions with affiliates as of July 21, 2011, including an expansion of the definition of “covered transactions” and an increase in the amount of time for which collateral requirements regarding covered transactions must be maintained.

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

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. The Bank has the authority under Iowa law to establish branches anywhere in the State of Iowa, subject to receipt of all required regulatory approvals.

Federal law permits state and national banks to merge with banks in other states subject to: (i) regulatory approval; (ii) federal and state deposit concentration limits; and (iii) state law limitations requiring the merging bank to have been in existence for a minimum period of time (not to exceed five years) prior to the merger. The establishment of new interstate branches 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) has historically been permitted only in those states the laws of which expressly authorize such expansion. However, the Dodd-Frank Act permits well-capitalized and well-managed banks to establish new branches across state lines without these impediments.

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

Transaction Account Reserves. Federal Reserve regulations require depository institutions to maintain reserves against their transaction accounts (primarily NOW and regular checking accounts). For 2013: the first $12.4 million of otherwise reservable balances are exempt from the reserve requirements; for transaction accounts aggregating more than $12.4 million to $79.5 million, the reserve requirement is 3% of total transaction accounts; and for net transaction accounts in excess of $79.5 million, the reserve

13

requirement is $2,013,000 plus 10% of the aggregate amount of total transaction accounts in excess of $79.5 million. These reserve requirements are subject to annual adjustment by the Federal Reserve. The Bank is in compliance with the foregoing requirements.

Consumer Financial Services. There are numerous developments in federal and state laws regarding consumer financial products and services that impact the Bank's business. Importantly, the current structure of federal consumer protection regulation applicable to all providers of consumer financial products and services changed significantly on July 21, 2011, when the CFPB commenced operations to supervise and enforce consumer protection laws. The CFPB has broad rulemaking authority for a wide range of consumer protection laws that apply to all providers of consumer products and services, including the Bank, as well as the authority to prohibit “unfair, deceptive or abusive” acts and practices. The CFPB has examination and enforcement authority over providers with more than $10 billion in assets. Banks and savings institutions with $10 billion or less in assets, like the Bank, will continue to be examined by their applicable bank regulators.

Ability-to-Repay Requirement and Qualified Mortgage Rule. The Dodd-Frank Act contains additional provisions that affect consumer mortgage lending. First, it significantly expands underwriting requirements applicable to loans secured by 1-4 family residential real property and augments federal law combating predatory lending practices. In addition to numerous new disclosure requirements, the Dodd-Frank Act imposes new standards for mortgage loan originations on all lenders, including banks and savings associations, in an effort to strongly encourage lenders to verify a borrower's ability to repay, while also establishing a presumption of compliance for certain “qualified mortgages.” Most significantly, the new standards limit the total points and fees that the Bank and/or a broker may charge on conforming and jumbo loans to 3% of the total loan amount. In addition, the Dodd-Frank Act generally requires lenders or securitizers to retain an economic interest in the credit risk relating to loans that the lender sells and other asset‑backed securities that the securitizer issues if the loans have not complied with the ability-to-repay standards. The risk retention requirement generally will be 5%, but could be increased or decreased by regulation.

On January 10, 2013, the CFPB issued a final rule, effective January 10, 2014, which implements the Dodd-Frank Act's ability-to-repay requirements and clarifies the presumption of compliance for “qualified mortgages.” In assessing a borrower's ability to repay a mortgage-related obligation, lenders generally must consider eight underwriting factors: (i) current or reasonably expected income or assets; (ii) current employment status; (iii) monthly payment on the subject transaction; (iv) monthly payment on any simultaneous loan; (v) monthly payment for all mortgage-related obligations; (vi) current debt obligations, alimony, and child support; (vii) monthly debt-to-income ratio or residual income; and (viii) credit history. The final rule also includes guidance regarding the application of, and methodology for evaluating, these factors.

Further, the final rule also clarifies that qualified mortgages do not include “no-doc” loans and loans with negative amortization, interest-only payments, balloon payments, terms in excess of 30 years, or points and fees paid by the borrower that exceed 3% of the loan amount, subject to certain exceptions. In addition, for qualified mortgages, the monthly payment must be calculated on the highest payment that will occur in the first five years of the loan, and the borrower's total debt-to-income ratio generally may not be more than 43%. The final rule also provides that certain mortgages that satisfy the general product feature requirements for qualified mortgages and that also satisfy the underwriting requirements of Fannie Mae and Freddie Mac (while they operate under federal conservatorship or receivership) or the U.S. Department of Housing and Urban Development, Department of Veterans Affairs, or Department of Agriculture or Rural Housing Service are also considered to be qualified mortgages. This second category of qualified mortgages will phase out as the aforementioned federal agencies issue their own rules regarding qualified mortgages, the conservatorship of Fannie Mae and Freddie Mac ends, and, in any event, after seven years.

As set forth in the Dodd-Frank Act, subprime (or higher-priced) mortgage loans are subject to the ability-to-repay requirement, and the final rule provides for a rebuttable presumption of lender compliance for those loans. The final rule also applies the ability-to-repay requirement to prime loans, while also providing a conclusive presumption of compliance (i.e., a safe harbor) for prime loans that are also qualified mortgages. Additionally, the final rule generally prohibits prepayment penalties (subject to certain exceptions) and sets forth a 3-year record retention period with respect to documenting and demonstrating the ability-to-repay requirement and other provisions.

Changes to Mortgage Loan Originator Compensation. Effective April 2, 2011, previously existing regulations concerning the compensation of mortgage loan originators were amended. As a result of these amendments, mortgage loan originators may not receive compensation based on a mortgage transaction's terms or conditions other than the amount of credit extended under the mortgage loan. Further, the new standards limit the total points and fees that a bank and/or a broker may charge on conforming and jumbo loans to 3% of the total loan amount. Mortgage loan originators may receive compensation from a consumer or from a lender, but not both. These rules contain requirements designed to prohibit mortgage loan originators from “steering” consumers to loans that provide mortgage loan originators with greater compensation. In addition, the rules contain other requirements concerning recordkeeping.

Foreclosure and Loan Modifications. Federal and state laws further impact foreclosures and loan modifications, with many of such laws having the effect of delaying or impeding the foreclosure process on real estate secured loans in default. Mortgages on commercial property can be modified, such as by reducing the principal amount of the loan or the interest rate, or by extending the term of the loan, through plans confirmed under Chapter 11 of the U.S. Bankruptcy Code. In recent years, legislation has been introduced in the U.S. Congress that would amend the Bankruptcy Code to permit the modification of mortgages secured by residences, although at this time the enactment of such legislation is not presently proposed. The scope, duration and terms of potential future legislation with similar effect continue to be discussed. We cannot predict whether any such legislation will be passed or the impact, if any, it would have on our business.

• our management’s ability to reduce and effectively manage interest rate risk and the impact of interest rates in general on the volatility of our net interest income;

• changes in the economic environment, competition, or other factors that may affect our ability to acquire loans or influence the anticipated growth rate of loans and deposits and the quality of the loan portfolio and loan and deposit pricing;

• fluctuations in the value of our investment securities;

• governmental monetary and fiscal policies;

• legislative and regulatory changes, including changes in banking, securities and tax laws and regulations and their application by our regulators (particularly with respect to the Dodd-Frank Act and the extensive regulations promulgated and to be promulgated thereunder, as well as rules proposed by the federal bank regulatory agencies to implement the Basel III capital accord), and changes in the scope and cost of FDIC insurance and other coverages;

• the ability to attract and retain key executives and employees experienced in banking and financial services;

• the sufficiency of the allowance for loan losses to absorb the amount of actual losses inherent in our existing loan portfolio;

• our ability to adapt successfully to technological changes to compete effectively in the marketplace;

• credit risks and risks from concentrations (by geographic area and by industry) within our loan portfolio;

• volatility of rate-sensitive deposits;

• operational risks, including data processing system failures or fraud;

• asset/liability matching risks and liquidity risks;

• the risks of mergers, acquisitions and divestitures, including, without limitation, the related time and costs of implementing such transactions, integrating operations as part of these transactions and possible failures to achieve expected gains, revenue growth and/or expense savings from such transactions;

15

• the costs, effects and outcomes of existing or future litigation;

• changes in general economic or industry conditions, nationally or in the communities in which we conduct business;

• changes in accounting policies and practices, as may be adopted by state and federal regulatory agencies and the Financial Accounting Standards Board; and

In addition, our past results of operations are not necessarily indicative of our future results.

ITEM 1A. RISK FACTORS.

An investment in our securities is subject to risks inherent in our business. Before making an investment decision, you should carefully consider the risks and uncertainties described below together with all of the other information included in this report. In addition to the risks and uncertainties described below, other 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 and results of operations. The value or market price of our securities could decline due to any of these identified or other risks, and you could lose all or part of your investment.

Our business has been and may continue to be adversely affected by conditions in the financial markets and economic conditions generally.

Although it has recently shown signs of improvement, since late 2007, the U.S. economy has generally experienced challenging economic conditions. Business activity across a range of industries and regions remains reduced from historical levels under more favorable economic conditions. Likewise, many local governments have been experiencing certain difficulties, including lower tax revenues, which have impacted their ability to cover costs. Unemployment also generally remains at elevated levels. For the past few years, the financial services industry has generally been affected by declines in the values of many significant asset classes, reduced levels of liquidity and the lack of opportunities to originate new loans. While these challenges are generally less severe than in recent years, their impact continues to be felt.

As a result of these economic conditions, many lending institutions, including the Bank, have experienced declines in the performance of their loans, including commercial loans, commercial and residential real estate loans and consumer loans, from historical norms. Moreover, competition among depository institutions for deposits and quality loans has increased significantly. In addition, the values of real estate collateral supporting many commercial loans and home mortgages remains distressed and may decline further in the future. Bank and bank holding company stock prices have generally been negatively affected over this time period, and the ability of banks and bank holding companies to raise capital or borrow in the debt markets has generally been more difficult than it had been prior to 2007. There have been significant new laws and regulations regarding lending and funding practices and liquidity standards, with a potential for further regulation in the future, and bank regulatory agencies in general have been very aggressive in responding to concerns and trends identified in examinations, including through formal or informal enforcement actions or orders. The impact of new legislation in response to these developments may negatively impact our operations by restricting our business operations, including our ability to originate or sell loans, and adversely impact our financial performance or our stock price.

In addition, if the overall economic climate in the United States, generally, or our market areas, specifically, fails to improve significantly, this may affect consumer confidence levels and may cause adverse changes in payment patterns, causing increases in delinquencies and default rates, which may impact our charge-offs and provisions for credit losses. A worsening of these conditions likely would exacerbate the adverse effects of the recent market conditions on us and others in the financial services industry. Since 2007, the general business environment has had an overall adverse effect on our business, and there can be no assurance that the environment will improve meaningfully in the near term. Until conditions materially improve, we expect our business, financial condition and results of operations to show measured improvement but to remain muted relative to their potential in more favorable economic conditions.

Interest rates and other conditions impact our results of operations.

Our profitability is in large part a function of the spread between the interest rates earned on investments and loans and the interest rates paid on deposits and other interest-bearing liabilities. Like most banking institutions, our net interest spread and margin is affected by general economic conditions and other factors, including fiscal and monetary policies of the federal government, that influence market interest rates and our ability to respond to changes in such rates. At any given time, our assets

16

and liabilities will be such that they are affected differently by a given change in interest rates. As a result, an increase or decrease in rates, the length of loan terms or the mix of adjustable and fixed rate loans in our portfolio could have a positive or negative effect on our net income, capital and liquidity. The competition for loans in the marketplace and the overall interest rate environment has kept interest rates on loans low. Interest rates paid on deposit products have declined steadily in recent years, but further significant decline is unlikely as interest rates on deposits have approached zero. We expect to continue battling net interest margin compression in 2013, with interest rates at generational lows.

We measure interest rate risk under various rate scenarios and using specific criteria and assumptions. A summary of this process, along with the results of our net interest income simulations, is presented at “Quantitative and Qualitative Disclosures about Market Risk” included under Item 7A of Part II of this Annual Report on Form 10-K. Although we believe our current level of interest rate sensitivity is reasonable and effectively managed, significant fluctuations in interest rates may have an adverse effect on our business, financial condition and results of operations.

Changes in interest rates also can affect the value of loans, securities and other assets. An increase in interest rates that adversely affects the ability of borrowers to pay the principal or interest on loans may lead to an increase in nonperforming assets and a reduction of income recognized, which could have a material adverse effect on our results of operations and cash flows. Further, when we place a loan on nonaccrual status, we reverse any accrued but unpaid interest receivable, which decreases interest income. Subsequently, we continue to have a cost to fund the loan, which is reflected as interest expense, without any interest income to offset the associated funding expense. Thus, an increase in the amount of nonperforming assets would have an adverse impact on net interest income.

Rising interest rates will likely result in a decline in value of our fixed-rate debt securities. The unrealized losses resulting from holding these securities would be recognized in other comprehensive income (or net income, if the decline is other-than-temporary), and reduce total shareholders’ equity. Unrealized losses do not negatively impact our regulatory capital ratios; however, tangible common equity and the associated ratios used by many investors would be reduced. If debt securities in an unrealized loss position are sold, such losses become realized and will reduce our regulatory capital ratios.

Our business is concentrated in and largely dependent upon the continued growth and welfare of the Iowa City and Oskaloosa markets and other markets in eastern and central Iowa.

We operate primarily in the Iowa City and Oskaloosa, Iowa, markets and their surrounding communities in eastern and central Iowa and, as a result, our financial condition, results of operations and cash flows are significantly impacted by changes in the economic conditions in those areas. Our success depends to a significant extent upon the business activity, population, income levels, deposits and real estate activity in these markets. Although our customers’ business and financial interests may extend well beyond these market areas, adverse economic conditions that affect these market areas could reduce our growth rate, affect the ability of our customers to repay their loans to us, affect the value of collateral underlying loans and generally affect our financial condition and results of operations. Because of our geographic concentration, we are less able than other regional or national financial institutions to diversify our credit risks across multiple markets. Although, in general, the Iowa economy and real estate market were not affected as severely as other areas of the United States in recent years, they are not immune to challenging economic conditions that affect the United States and world economies.

We must manage our credit risk effectively.

There are risks inherent in making any loan, including risks inherent in dealing with individual borrowers, risks of nonpayment, risks resulting from uncertainties as to the future value of collateral and risks resulting from changes in economic and industry conditions. We attempt to minimize our credit risk through prudent loan application approval procedures, careful monitoring of the concentration of our loans within specific industries and periodic independent reviews of outstanding loans by our credit review department. However, we cannot assure you that such approval and monitoring procedures will reduce these credit risks.

If the overall economic climate in the United States, generally, or our market areas, specifically, fails to meaningfully improve, or even if it does, our borrowers may experience difficulties in repaying their loans, and the level of nonperforming loans, charge-offs and delinquencies could rise and require increases in the provision for loan losses, which would cause our net income and return on equity to decrease.

A significant portion of the Bank’s loan portfolio consists of commercial loans, and we focus on lending to small to medium-sized businesses. The size of the loans we can offer to commercial customers is less than the size of the loans that our competitors with larger lending limits can offer. This may limit our ability to establish relationships with the area’s largest businesses. As a result, we may assume greater lending risks than financial institutions that have a lesser concentration of such loans and tend

17

to make loans to larger businesses. Collateral for these loans generally includes accounts receivable, inventory, equipment and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. In addition to commercial loans and commercial real estate loans, MidWestOne Bank is also active in residential mortgage and consumer lending. Should the economic climate worsen, our borrowers may experience financial difficulties, and the level of nonperforming loans, charge-offs and delinquencies could rise, which could negatively impact our business.

Commercial, industrial and agricultural loans make up a significant portion of our loan portfolio.

Commercial, industrial and agricultural loans (including credit cards and commercially related overdrafts), were $323.3 million, or approximately 31.1% of our total loan portfolio, as of December 31, 2012. Our commercial loans are primarily made based on the identified cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. Most often, this collateral is accounts receivable, inventory and equipment. Credit support provided by the borrower for most of these loans and the probability of repayment is based on the liquidation value of the pledged collateral and enforcement of a personal guarantee, if any exists. As a result, in the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. The collateral securing these loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business. In addition, if the United States economy fails to improve meaningfully, this could harm the businesses of our commercial and industrial customers and reduce the value of the collateral securing these loans.

Payments on agricultural loans are dependent on the successful operation or management of the farm property. The success of the farm may be affected by many factors outside the control of the borrower, including adverse weather conditions that prevent the planting of a crop or limit crop yields (such as hail, drought and floods), loss of livestock due to disease or other factors, declines in market prices for agricultural products (both domestically and internationally) and the impact of government regulations (including changes in price supports, subsidies and environmental regulations). In addition, many farms are dependent on a limited number of key individuals whose injury or death may significantly affect the successful operation of the farm. If the cash flow from a farming operation is diminished, the borrower’s ability to repay the loan may be impaired. The primary crops in our market areas are corn and soybeans. Accordingly, adverse circumstances affecting these crops could have an adverse effect on our agricultural real estate loan portfolio. Likewise, agricultural operating loans involve a greater degree of risk than lending on residential properties, particularly in the case of loans that are unsecured or secured by rapidly depreciating assets such as farm equipment or assets such as livestock or crops. In these cases, any repossessed collateral for a defaulted loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation.

Our loan portfolio has a significant concentration of commercial real estate loans, which involve risks specific to real estate value.

Commercial real estate lending comprises a significant portion of our lending business. Specifically, commercial real estate loans were $440.0 million, or approximately 42.5% of our total loan portfolio, as of December 31, 2012. Of this amount, $118.1 million, or approximately 11.4%, of our total loan portfolio are loans secured by owner-occupied property. The market value of real estate securing our commercial real estate loans can fluctuate significantly in a short period of time as a result of market conditions in the geographic area in which the real estate is located. Although a significant portion of such loans is secured by real estate as a secondary form of repayment, adverse developments affecting real estate values in one or more of our markets could increase the credit risk associated with our loan portfolio. Additionally, real estate lending typically involves higher loan principal amounts and the repayment of the loans generally is dependent, in large part, on sufficient income from the properties securing the loans to cover operating expenses and debt service. Economic events or governmental regulations outside of the control of the borrower or lender could negatively impact the future cash flow and market values of the affected properties.

If problems develop in the commercial real estate market, particularly within one or more of our markets, the value of collateral securing our commercial real estate loans could decline. In such case, we may not be able to realize the amount of security that we anticipated at the time of originating the loan, which could cause us to increase our provision for loan losses and adversely affect our operating results, financial condition and/or capital. We generally have not experienced a downturn in credit performance by our commercial real estate loan customers, but in light of the general uncertainty that exists in the economy and credit markets nationally, there can be no guarantee that we will not experience any deterioration in such performance.

Our allowance for loan losses may prove to be insufficient to absorb losses in our loan portfolio.

We established our allowance for loan losses in consultation with the credit officers of MidWestOne Bank and maintain it at a level considered adequate by management to absorb probable loan losses that are inherent in the portfolio. The amount of future loan losses is susceptible to changes in economic, operating and other conditions, including changes in interest rates and the value of the underlying collateral, which are beyond our control, and such losses may exceed current estimates. At December 31,

18

2012, our allowance for loan losses as a percentage of total gross loans was 1.54% and as a percentage of total nonperforming loans was approximately 149.8%. Although management believes that the allowance for loan losses is adequate to absorb losses on any existing loans that may become uncollectible, we cannot predict loan losses with certainty, and we cannot assure you that our allowance for loan losses will prove sufficient to cover actual loan losses in the future. Loan losses in excess of our reserves may adversely affect our business, financial condition and results of operations.

Nonperforming assets take significant time to resolve and adversely affect our results of operations and financial condition, and could result in further losses in the future.

As of December 31, 2012, our nonperforming loans (which consist of nonaccrual loans, loans past due 90 days or more and still accruing interest and loans modified under troubled debt restructurings) totaled $10.7 million, or 1.03% of our loan portfolio, and our nonperforming assets (which include nonperforming loans plus other real estate owned) totaled $13.9 million, or 1.35% of loans. In addition, we had $6.1 million in accruing loans that were 31-89 days delinquent as of December 31, 2012.

Our nonperforming assets adversely affect our net income in various ways. We do not record interest income on nonaccrual loans or other real estate owned, thereby adversely affecting our net income and returns on assets and equity, increasing our loan administration costs and adversely affecting our efficiency ratio. When we take collateral in foreclosure and similar proceedings, we are required to mark the collateral to its then-fair market value, which may result in a loss. These nonperforming loans and other real estate owned also increase our risk profile and the capital our regulators believe is appropriate in light of such risks. The resolution of nonperforming assets requires significant time commitments from management and can be detrimental to the performance of their other responsibilities. If we experience increases in nonperforming loans and nonperforming assets, our net interest income may be negatively impacted and our loan administration costs could increase, each of which could have an adverse effect on our net income and related ratios, such as return on assets and equity.

The repeal of federal prohibitions on payment of interest on business demand deposits could increase our interest expense.

All federal prohibitions on the ability of financial institutions to pay interest on business demand deposit accounts were repealed as part of the Dodd-Frank Act. As a result, some financial institutions have commenced offering interest on these demand deposits to compete for customers. If competitive pressures require us to pay interest on these demand deposits to attract and retain business customers, our interest expense would increase and our net interest margin would decrease. This could have a material adverse effect on our business, financial condition and results of operations. Further, the effect of the repeal of the prohibition could be more significant in a higher interest rate environment as business customers would have a greater incentive to seek interest on demand deposits.

We could recognize losses on securities held in our securities portfolio, particularly if interest rates increase or economic and market conditions deteriorate.

As of December 31, 2012, the fair value of our securities portfolio was approximately $590.2 million. Factors beyond our control can significantly influence the fair value of securities in our portfolio and can cause potential adverse changes to the fair value of these securities. For example, fixed-rate securities acquired by us are generally subject to decreases in market value when interest rates rise. Additional factors include, but are not limited to, rating agency downgrades of the securities, defaults by the issuer or individual mortgagors with respect to the underlying securities, and instability in the credit markets. Any of the foregoing factors could cause an other-than-temporary impairment in future periods and result in realized losses. The process for determining whether impairment is other-than-temporary usually requires difficult, subjective judgments about the future financial performance of the issuer and any collateral underlying the security in order to assess the probability of receiving all contractual principal and interest payments on the security. Because of changing economic and market conditions affecting interest rates, the financial condition of issuers of the securities and the performance of the underlying collateral, we may recognize realized and/or unrealized losses in future periods, which could have an adverse effect on our financial condition and results of operations.

We have investments in pools of performing and nonperforming loans that generate a material amount of interest income with yields that may fluctuate considerably resulting in inconsistent profitability from period to period.

Although we decided to exit our loan pool participation line of business in 2010, we continue to hold investments in certain loan pools until their balances pay down. As of December 31, 2012, approximately 2% of our earning assets were invested in loan pool participations, and approximately 3% of our gross total revenue for the year ended December 31, 2012 was derived from the loan pool participations. These loan pool participations represent a mixture of performing, subperforming and nonperforming loans. As of December 31, 2012, our loan pool investment of $37.8 million consisted of loans secured by commercial real estate (64.4%), commercial operating (6.3%), single-family residential real estate (12.7%), and other loans (16.6%). The loan pool investment is a “nontraditional” activity that has, until recent years, provided us and our predecessor entities with a higher

19

return than typical loans and investment securities. The return on investment in loan pool participations and the effect on profitability can be unpredictable due to fluctuations in the balance of loan pool participations and collections from borrowers by the loan pool servicer. Loan pool balances can be affected by the payment and refinancing activities of the borrowers resulting in pay-offs of the underlying loans and reduction in the balances. Collections from the individual borrowers are managed by the loan pool servicer and are affected by the borrower’s financial ability and willingness to pay, foreclosure and legal action, collateral value, and the economy in general. Any of these identified factors, and others not identified, could affect our return on loan pool investments.

Although we did not seek to purchase consumer or consumer real estate loans characterized as subprime or Alt-A credits, because the purchases of these assets was on a pool basis, we have acquired some subprime loans as characterized by borrowers or guarantors having FICO scores below 640. Consumer-based paper makes up approximately 9.9% of our loan pool investment and, as of December 31, 2012, approximately 0.8% of the basis amount of our loan pool investment represented subprime credit. Because we do not originate the consumer-based loans that may be characterized as Alt-A, and because of the nature of the information provided to us with respect to any Alt-A loans in the loan pool participations, we are not able to verify the basis amount of our loan pool investment that represents Alt-A credit. Loans that are characterized as subprime and, to a lesser extent, Alt-A carry a higher risk of default by the underlying borrowers than other types of loans, which could affect the value of the overall loan pool investment.

Downgrades in the credit rating of one or more insurers that provide credit enhancement for our state and municipal securities portfolio may have an adverse impact on the market for and valuation of these types of securities.

We invest in tax-exempt state and local municipal securities, some of which are insured by monoline insurers. As of December 31, 2012, we had $237.3 million of municipal securities, which represented 39.1% of our total securities portfolio. Since the economic crisis unfolded in 2008, several of these insurers have come under scrutiny by rating agencies. Even though management generally purchases municipal securities on the overall credit strength of the issuer, the reduction in the credit rating of an insurer may negatively impact the market for and valuation of our investment securities. Such a downgrade could adversely affect our liquidity, financial condition and results of operations.

We may desire or be required to raise additional capital in the future, but that capital may not be available.

We are required by federal and state regulatory authorities to maintain adequate levels of capital to support our operations. We intend to grow our business organically and to explore opportunities to grow our business by taking advantage of attractive acquisition opportunities, including through FDIC-assisted transactions, and such growth plans may require us to raise additional capital to ensure that we have adequate levels of capital to support such growth on top of our current operations. We may at some point need to raise additional capital to support our growth plans and in this regard, in early 2013, we renewed our universal shelf-registration statement registering for future sale up to $25 million of securities that places us in a position to raise capital if the need were to arise or if an attractive opportunity were presented. Our ability to raise additional capital will depend on conditions in the capital markets, economic conditions and a number of other factors, including investor perceptions regarding the banking industry, market conditions and governmental activities, and on our financial condition and performance. Accordingly, we cannot assure you of our ability to raise additional capital, if needed or desired, on terms acceptable to us. If we cannot raise additional capital when needed or desired, our ability to further expand our operations through internal growth or acquisitions could be materially impaired.

We may experience difficulties in managing our growth, and our growth strategy involves risks that may negatively impact our net income.

Although we do not have any current definitive plans to do so, we may expand into additional communities or attempt to strengthen our position in our current markets through opportunistic acquisitions of all or part of other financial institutions, including through FDIC-assisted transactions, or by opening new branches. To the extent that we undertake acquisitions or new branch openings, we are likely to experience the effects of higher operating expenses relative to operating income from the new operations, which may have an adverse effect on our levels of reported net income, return on average equity and return on average assets. Other effects of engaging in such growth strategies may include potential diversion of our management’s time and attention and general disruption to our business.

To the extent that we grow through acquisitions or branch openings, we cannot assure you that we will be able to adequately and profitably manage this growth. Acquiring other banks and businesses will involve similar risks to those commonly associated with branching, but may also involve additional risks, including:

• potential exposure to unknown or contingent liabilities of banks and businesses we acquire;

• exposure to potential asset quality issues of the acquired bank or related business;

20

• difficulty and expense of integrating the operations and personnel of banks and businesses we acquire; and

• the possible loss of key employees and customers of the banks and businesses we acquire.

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

Liquidity is essential to our business. An inability to raise funds through deposits, borrowings, the sale of loans and other sources could have a substantial negative effect on our liquidity. Our primary sources of funds consist of cash from operations, investment maturities and sales, deposits and funds from sales of capital securities. Additional liquidity is provided by brokered deposits, bank lines of credit, repurchase agreements and the ability to borrow from the Federal Reserve Bank and the Federal Home Loan Bank. Our access to funding sources in amounts adequate to finance or capitalize our activities or on terms that are acceptable to us could be impaired by factors that affect us directly or the financial services industry or economy in general, such as disruptions in the financial markets or negative views and expectations about the prospects for the financial services industry.

In recent years, the financial services industry and the credit markets generally have been materially and adversely affected by significant declines in asset values and by historically depressed levels of liquidity. The liquidity issues have been particularly acute for regional and community banks, as many of the larger financial institutions have curtailed their lending to regional and community banks to reduce their exposure to the risks of other banks. In addition, many of the larger correspondent lenders have reduced or even eliminated federal funds lines for their correspondent customers. Furthermore, regional and community banks generally have less access to the capital markets than do the national and super-regional banks because of their smaller size and limited analyst coverage.

As a result, we rely more on our ability to generate deposits and effectively manage the repayment and maturity schedules of our loans and investment securities, respectively, to ensure that we have adequate liquidity to fund our operations. Any decline in available funding could adversely impact our ability to originate loans, invest in securities, meet our expenses, pay dividends to our stockholders, or to fulfill obligations such as repaying our borrowings or meeting deposit withdrawal demands, any of which could have a material adverse impact on our liquidity, business, financial condition and results of operations.

The December 31, 2012 expiration of the FDIC's Transaction Account Guarantee Program could negatively impact the Bank's liquidity and cost of funds.

Under the FDIC's Transaction Account Guarantee Program, certain non-interest-bearing transaction accounts, including those of consumers and businesses, were insured by the FDIC over and above the customary $250,000 limit through December 31, 2012, the date on which this program expired.  The expiration of this program could cause depositors of the Bank to withdraw deposits in excess of FDIC-insured levels. The withdrawal of these deposits could negatively impact the Bank's liquidity. Furthermore, the withdrawal of these deposits could negatively impact the Bank's cost of funds by potentially reducing its level of core deposits and increasing its need to rely on wholesale funding sources, which typically represent higher cost funds.

Legislative and regulatory actions taken now or in the future may increase our costs and impact our business, governance structure, financial condition or results of operations.

The Company and the Bank are subject to extensive regulation by multiple regulatory bodies.  These regulations may affect the manner and terms of delivery of our services.  If we do not comply with governmental regulations, we may be subject to fines, penalties, lawsuits or material restrictions on our businesses in the jurisdiction where the violation occurred, which may adversely affect our business operations.  Changes in these regulations can significantly affect the services that we provide, as well as our costs of compliance with such regulations. In addition, 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.

Economic conditions in recent years, particularly in the financial markets, have resulted in government regulatory agencies and political bodies placing increased focus and scrutiny on the financial services industry.  In recent years the U.S. government has intervened on an unprecedented scale by temporarily enhancing the liquidity support available to financial institutions. This environment has subjected financial institutions to additional restrictions, oversight and costs.  In addition, new legislative and regulatory proposals continue to be introduced that could further substantially increase the oversight of the financial services industry, impose restrictions on the operations and general ability of firms within the industry to conduct business consistent with historical practices, including in the areas of compensation, interest rates, financial product offerings and disclosures, and have an effect on bankruptcy proceedings with respect to consumer residential real estate mortgages, among other things. If these regulatory trends continue, they could adversely affect our business and, in turn, our consolidated results of operations.

21

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

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

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

Legislative and regulatory reforms applicable to the financial services industry may, if enacted or adopted, have a significant impact on our business, financial condition and results of operations.

On July 21, 2010, the Dodd-Frank Act was signed into law, which requires significant changes to the regulation of financial institutions and the financial services industry.  The Dodd-Frank Act, together with the regulations developed and to be developed thereunder, includes provisions affecting large and small financial institutions alike, including several provisions that will affect how community banks, thrifts and small bank and thrift holding companies will be regulated in the future.

Ultimately, the Dodd-Frank Act will, among other things: impose new capital requirements on bank holding companies; change the base for FDIC insurance assessments to a bank’s average consolidated total assets minus average tangible equity, rather than upon its deposit base; permanently raise the standard deposit insurance limit to $250,000; and expand the FDIC’s authority to raise insurance premiums.  The legislation also called for the FDIC to raise the ratio of reserves to deposits from 1.15% to 1.35% for deposit insurance purposes by September 30, 2020 and to “offset the effect” of increased assessments on insured depository institutions with assets of less than $10 billion.  The Dodd-Frank Act also authorized the Federal Reserve to limit interchange fees payable on debit card transactions, allowed financial institutions to pay interest on business checking accounts, established the Bureau of Consumer Financial Protection as an independent entity within the Federal Reserve, with broad rulemaking, supervisory and enforcement authority over consumer financial products and services, including deposit products, residential mortgages, home-equity loans and credit cards, and contains provisions on mortgage-related matters, such as steering incentives, determinations as to a borrower’s ability to repay and prepayment penalties.  The Dodd-Frank Act also includes provisions that have affected, and will further affect in the future, corporate governance and executive compensation at all publicly-traded companies.

The Group of Governors and Heads of Supervision, the oversight body of the Basel Committee on Banking Supervision, adopted Basel III in September 2010, which constitutes a strengthened set of capital requirements for banking organizations in the United States and around the world. Basel III is currently the subject of notices of proposed rulemakings released in June of 2012 by the respective U.S. federal banking agencies. The comment period for these notices of proposed rulemakings ended on October 22, 2012, but final regulations have not yet been released. Basel III was intended to be implemented beginning January 1, 2013 and to be fully-phased in on a global basis on January 1, 2019. However, on November 9, 2012, the U.S. federal bank regulatory agencies announced that the implementation of the proposed rules to effect Basel III in the United States was indefinitely delayed. Basel III would require capital to be held in the form of tangible common equity, generally increase the required capital ratios, phase out certain kinds of intangibles treated as capital and certain types of instruments, like trust preferred securities, and change the risk weightings of assets used to determine required capital ratios.

These provisions, or any other aspects of current or proposed regulatory or legislative changes to laws applicable to the financial industry, if enacted or adopted, may impact the profitability of our business activities or change certain of our business practices, including the ability to offer new products, obtain financing, attract deposits, make loans, and achieve satisfactory interest spreads, and could expose us to additional costs, including increased compliance costs.  These changes also may require us to invest significant management attention and resources to make any necessary changes to operations in order to comply, and could therefore also materially and adversely affect our business, financial condition and results of operations.  Our management continues to stay abreast of developments with respect to the Dodd-Frank Act, many provisions of which will continue to be phased-in over the next several months and years, and Basel III, the implementation of which has been delayed, and continues to assess their impact on our operations.  The ultimate effect of these regulations on the financial services industry in general, and us in particular, cannot be quantified at this time.

Our ability to pay dividends is subject to certain limitations and restrictions, and there is no guarantee that we will be able to continue paying the same level of dividends in the future that we paid in 2012 or that we will be able to pay future dividends at all.

Our ability to pay dividends is limited by regulatory restrictions and the need to maintain sufficient consolidated capital. The ability of MidWestOne Bank to pay dividends to us is limited by its obligations to maintain sufficient capital and liquidity and by other general restrictions on dividends that are applicable to MidWestOne Bank, including the requirement under the Iowa Banking Act that it may not pay dividends in excess of its accumulated net profits. If these regulatory requirements are not met, MidWestOne Bank will not be able to pay dividends to us, and we may be unable to pay dividends on our common stock.

In addition, as a bank holding company, our ability to declare and pay dividends is subject to the guidelines of the Federal Reserve regarding capital adequacy and dividends. The Federal Reserve guidelines generally require us to review the effects of the cash payment of dividends on common stock and other Tier 1 capital instruments (i.e., perpetual preferred stock and trust preferred debt) in light of our earnings, capital adequacy and financial condition. As a general matter, the Federal Reserve indicates that the board of directors of a bank holding company (including a financial holding company) should eliminate, defer or significantly reduce the Company’s dividends if:

• the company’s net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends;

• the prospective rate of earnings retention is inconsistent with the company’s capital needs and overall current and prospective financial condition; or

• the company will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios.

As of December 31, 2012, we had $15.5 million of junior subordinated debentures held by a statutory business trust that we control. Interest payments on the debentures, which totaled $0.7 million for the year ended December 31, 2012, must be paid before we pay dividends on our capital stock, including our common stock. We have the right to defer interest payments on the debentures for up to 20 consecutive quarters. However, if we elect to defer interest payments, all deferred interest must be paid before we may pay dividends on our capital stock.

Our ability to attract and retain management and key personnel may affect future growth and earnings.

Much of our success and growth has been influenced by our ability to attract and retain management experienced in banking and financial services and familiar with the communities in our market areas. Our ability to retain our executive officers, current management teams, branch managers and loan officers will continue to be important to the successful implementation of our strategy. It is also critical, as we grow, to be able to attract and retain qualified additional management and loan officers with the appropriate level of experience and knowledge about our market areas to implement our community‑based operating strategy. The Dodd-Frank Act also directs the Federal Reserve to promulgate rules prohibiting excessive compensation paid to bank holding company executives. These rules, when adopted, may make it more difficult to attract and retain the people we need to operate our businesses and limit our ability to promote our objectives through our compensation and incentive programs. The unexpected loss of services of any key management personnel, or the inability to recruit and retain qualified personnel in the future, could have an adverse effect on our business, results of operations and financial condition.

We face intense competition in all phases of our business from banks and other financial institutions.

The banking and financial services businesses in our markets are highly competitive. Our competitors include large regional banks, local community banks, savings and loan associations, securities and brokerage companies, mortgage companies, insurance companies, finance companies, money market mutual funds, small local credit unions as well as large aggressive and expansion-minded credit unions, and other nonbank financial services providers. Many of these competitors are not subject to the same regulatory restrictions as we are. Many of our unregulated competitors compete across geographic boundaries and are able to provide customers with a competitive alternative to traditional banking services.

Increased competition in our markets may result in a decrease in the amounts of our loans and deposits, reduced spreads between loan rates and deposit rates or loan terms that are more favorable to the borrower. Any of these results could have a material adverse effect on our ability to grow and remain profitable. If increased competition causes us to significantly discount the interest rates we offer on loans or increase the amount we pay on deposits, our net interest income could be adversely impacted. If increased competition causes us to modify our underwriting standards, we could be exposed to higher losses from lending activities. Additionally, many of our competitors are much larger in total assets and capitalization, have greater access to capital markets, have larger lending limits and offer a broader range of financial services than we can offer.

23

We have a continuing need for technological change, and we may not have the resources to effectively implement new technology.

The financial services industry continues to undergo rapid technological changes with frequent introductions of new technology-driven products and services. In addition to enabling us to better serve our customers, the effective use of technology increases efficiency and the potential for cost reduction. Our future success will depend in part upon our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience as well as to create additional efficiencies in our operations as we continue to grow our market share. Many of our larger competitors have substantially greater resources to invest in technological improvements. As a result, they may be able to offer additional or superior products to those that we will be able to offer, which could put us at a competitive disadvantage. Accordingly, we cannot provide you with assurance that we will be able to effectively implement new technology-driven products and services or be successful in marketing such products and services to our customers.

System failure or breaches of our network security could subject us to increased operating costs as well as litigation and other liabilities.

The computer systems and network infrastructure we use could be vulnerable to unforeseen problems. Our operations are dependent upon our ability to protect our computer equipment against damage from physical theft, fire, power loss, telecommunications failure or a similar catastrophic event, as well as from security breaches, denial of service attacks, viruses, worms and other disruptive problems caused by hackers. Any damage or failure that causes an interruption in our operations could have a material adverse effect on our financial condition and results of operations. Computer break-ins, phishing and other disruptions could also jeopardize the security of information stored in and transmitted through our computer systems and network infrastructure, as well as that of our customers engaging in Internet banking activities, which may result in significant liability to us and may cause existing and potential customers to refrain from doing business with us. Although we, with the help of third-party service providers, intend to continue to implement security technology and establish operational procedures to prevent such damage, there can be no assurance that these security measures will be successful. In addition, advances in computer capabilities, new discoveries in the field of cryptography or other developments could result in a compromise or breach of the algorithms we and our third-party service providers use to encrypt and protect customer transaction data. Any interruption in, or breach in security of, our computer systems and network infrastructure, or that of our Internet banking customers, could damage our reputation, result in a loss of customer business, subject us to additional regulatory scrutiny, or expose us to civil litigation and possible financial liability, any of which could have a material adverse effect on our financial condition and results of operations.

We are subject to certain operational risks, including, but not limited to, customer or employee fraud and data processing system failures and errors.

Employee errors and employee and customer misconduct could subject us to financial losses or regulatory sanctions and seriously harm our reputation. Misconduct by our employees could include hiding unauthorized activities from us, improper or unauthorized activities on behalf of our customers or improper use of confidential information. It is not always possible to prevent employee errors and misconduct, and the precautions we take to prevent and detect this activity may not be effective in all cases. Employee errors could also subject us to financial claims for negligence.

We maintain a system of internal controls and insurance coverage to mitigate against operational risks, including data processing system failures and errors and customer or employee fraud. Should our internal controls fail to prevent or detect an occurrence, and if any resulting loss is not insured or exceeds applicable insurance limits, such failure could have a material adverse effect on our business, financial condition and results of operations.

Adverse weather affecting the markets we serve could hurt our business and prospects for growth.

Substantially all of our business is conducted in the State of Iowa, and a significant portion is conducted in rural communities. The Iowa economy, in general, is heavily dependent on agriculture and therefore the overall Iowa economy, and particularly the economies of the rural communities that we serve, can be greatly affected by severe weather conditions, including droughts, storms, tornadoes and flooding. Unfavorable weather conditions may decrease agricultural productivity or could result in damage to our branch locations or the property of our customers, all of which could adversely affect the local economy. An adverse affect on the economy of Iowa would negatively affect our profitability.

Our reputation could be damaged by negative publicity.

Reputational risk, or the risk to our business, financial condition or results of operations from negative publicity, is inherent in our business. Negative publicity can result from actual or alleged conduct in a number of areas, including legal and regulatory

24

compliance, lending practices, corporate governance, litigation, inadequate protection of customer data, ethical behavior of our employees, and from actions taken by regulators, ratings agencies and others as a result of that conduct. Damage to our reputation could impact our ability to attract new or maintain existing loan and deposit customers, employees and business relationships.

We have counterparty risk and therefore we may be adversely affected by the soundness of other financial institutions.

Our ability to engage in routine funding and other transactions could be negatively affected by the actions and the soundness of other financial institutions. Financial services institutions are generally interrelated as a result of trading, clearing, counterparty, credit or other relationships. We have exposure to many different industries and counterparties and regularly engage in transactions with counterparties in the financial services industry, including commercial banks, brokers and dealers, investment banks and other institutional customers. Many of these transactions may expose us to credit or other risks if another financial institution experiences adverse circumstances. In certain circumstances, the collateral that we hold may be insufficient to fully cover the risk that a counterparty defaults on its obligations, which may cause us to experience losses that could have a material adverse effect on our business, financial condition and results of operations.

There is a limited trading market for our common shares, and you may not be able to resell your shares at or above the price you paid for them.

Although our common shares are listed for quotation on The NASDAQ Global Select Market, the trading in our common shares has substantially less liquidity than many other companies listed on NASDAQ. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence in the market of willing buyers and sellers of our common shares at any given time. This presence depends on the individual decisions of investors and general economic and market conditions over which we have no control. We cannot assure you that the volume of trading in our common shares will increase in the future.

Certain MidWestOne shareholders own a significant interest in the company and may exercise their control in a manner detrimental to your interests.

Certain MidWestOne shareholders who are descendants of our founder collectively control approximately 33.2% of our outstanding common stock and may have the opportunity to exert influence on the outcome of matters required to be submitted to shareholders for approval. In addition, this significant level of ownership by members of the founding family may contribute to the rather limited liquidity of our common stock on the NASDAQ Global Select Market.

ITEM 2. PROPERTIES.

Our headquarters and MidWestOne Bank’s main office are located at 102 South Clinton Street, Iowa City, Iowa, and consist of approximately 63,800 square feet. We currently operate 24 additional branches throughout central and east-central Iowa totaling approximately 120,000 square feet. The table below sets forth the locations of the Bank’s branch offices:

In addition to the Bank’s branch offices, the insurance subsidiary leases one property totaling approximately 4,800 square feet at 309 High Avenue East, Oskaloosa, Iowa.   The Bank owns 40 ATMs that are located within the communities served by branch offices.  We believe each of our facilities is suitable and adequate to meet our current operational needs.

In February 2012 we relocated our Belle Plaine office to a new full service branch facility with attached drive up, at which time we closed our former Belle Plaine office. The new office not only increased the efficiency of our operations in Belle Plaine, but was necessitated by continued market growth in the community. In the second quarter of 2012 we completed the sale of our former Home Mortgage Center (”HMC”) office to the University of Iowa for their future building plans. Our HMC operation then relocated to leased space at 509 South Dubuque Street in Iowa City, approximately one block away from our former building, where it will remain pending the eventual construction of a new building next to the current leased space.

26

ITEM 3. LEGAL PROCEEDINGS.

We and our subsidiaries are from time to time parties to various legal actions arising in the normal course of business.  We believe that there is no threatened or pending proceeding against us or our subsidiaries, which, if determined adversely, would have a material adverse effect on our consolidated business or financial condition.

ITEM 4. MINE SAFETY DISCLOSURES.

Not applicable.

Dividends

We may pay dividends on our common stock as and when declared by our Board of Directors out of any funds legally available for the payment of such dividends, subject to any and all preferences and rights of any preferred stock or a series thereof. The amount of dividend payable will depend upon our earnings and financial condition and other factors, including applicable governmental regulations and policies. See “Supervision and Regulation - The Company - Dividend Payments”

Repurchases of Company Equity Securities

On July 26, 2011, our Board of Directors authorized the implementation of a share repurchase program to repurchase up to $1.0 million of the Company’s outstanding shares of common stock through December 31, 2011. Pursuant to the program, we repurchased 45,039 shares of common stock during the third quarter of 2011 for an aggregate cost of $658,000. On October 18, 2011, our Board of Directors amended the Company’s share repurchase program by increasing the remaining amount of authorized repurchases to $5.0 million, and extending the expiration of the program to December 31, 2012. For the year of 2012 we repurchased a total of 104,518 shares of common stock at a cost of $1.8 million, with $2.4 million remaining in the share repurchase program at December 31, 2012, the expiration date of this program.

On January 15, 2013, our Board of Directors announced the renewal of the Company's share repurchase program, extending the expiration of the program to December 31, 2014 and increasing the remaining amount of authorized repurchases under the program to $5.0 million from the approximately $2.4 million of authorized repurchases that had previously remained. Pursuant to the program, we may continue to repurchase shares from time to time in the open market, and the method, timing and amounts of repurchase will be solely in the discretion of the Company's management. The repurchase program does not require us to acquire

27

a specific number of shares. Therefore, the amount of shares repurchased pursuant to the program will depend on several factors, including market conditions, capital and liquidity requirements, and alternative uses for cash available.

The following table sets forth information about the Company’s purchases of its common stock in the 4th quarter of 2012:

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

Overview

We are the holding company for MidWestOne Bank, an Iowa state non-member bank with its main office in Iowa City, Iowa. We are headquartered in Iowa City, Iowa, and are a bank holding company under the Bank Holding Company Act of 1956 that has elected to be a financial holding company. We also are the holding company for MidWestOne Insurance Services, Inc., which operates an insurance business through three agencies located in central and east-central Iowa.

MidWestOne Bank operates a total of 25 branch locations, plus its specialized Home Mortgage Center, in 15 counties throughout central and east-central Iowa. It provides full service retail banking in the communities in which its branch offices are and also offers trust and investment management services.

On March 14, 2008, we consummated our merger with the Former MidWestOne. Prior to such merger, we were named ISB Financial Corp. The results of operations for the year ended December 31, 2008, include our operations for the entire year as well as the operations of Former MidWestOne for the period beginning March 15, 2008, through December 31, 2008. That is, the results of operations include approximately two and one-half months of our stand-alone operations and nine and one-half months of the operations of the Company and Former MidWestOne on a consolidated basis. The results of operations for the years ended December 31, 2009, 2010, 2011, and 2012 include the operations of the combined Company for the entire period.

We reported record earnings in 2012. Company net income available to common shareholders was $16.8 million in 2012 which was a 32.2% increase over 2011's net income available to common shareholders of $12.7 million. Diluted earnings per share for 2012 were $1.96 per share, 33.3% higher than 2011's $1.47. For the second consecutive year we set an all-time record in net income and earnings per share. Return on assets (“ROA”) and return on tangible common equity (“ROTCE”) for the full year of 2012 of 0.97% and 11.09%, respectively, are well ahead of the 0.82% and 9.51%, respectively, for 2011. In the second quarter of 2012 we realized a $4.0 million gain on the sale of our Home Mortgage Center and a $6.1 million loss on the termination of our defined benefit pension plan. Excluding the effect of these two large non-recurring items that produced an after-tax net loss of $1.3 million, the ROA improves to 1.05% and the ROTCE improves to 11.92%.

The Company continues to grow and ended 2012 with assets of $1.8 billion which was $97.6 million higher than 2011 year ending assets of $1.7 billion. Total deposits increased during the year by more than $93.0 million to end 2012 at $1.4 billion. Bank loans also continued to increase, and ended the year at $1.0 billion, an increase of $49.1 million from December 31, 2011. This growth in assets continued to fuel growth in net interest income. Net interest income grew by 9.3% or $4.6 million for 2012 relative to the year ended December 31, 2011. Of concern is the Federal Reserve's low interest rate policy and the pressure it places on both MidWestOne and the banking industry generally in efforts to grow or maintain net interest margins.

Most components of our noninterest income performed very well during 2012. Trust, investment and insurance fees were 10.1% higher than in 2011. Mortgage origination and loan servicing fees were $887,000 or 33.0% higher for 2012 than for 2011, due primarily to the current interest rate environment. Despite these general increases, continued restrictive federal regulations have resulted in across the board reductions in service charges and fees on deposit accounts; not only at MidWestOne but at many financial institutions. Service charges declined 12.3% in 2012 compared to 2011. The efficiency ratio showed improvement during 2012. When the aforementioned large one-time items are excluded, the efficiency ratio for the Company declined to 58.82% in 2012 from 62.94% in 2011. It is important that we continue to keep efficiency at these or better levels in order to meet our long term financial goals.

33

By any measure, asset quality continues to be strong. The net bank loan charge-off rate as a percentage of average bank loans outstanding was 0.21% for 2012 compared to 0.30% in 2011. At year-end, non-performing loans were 1.03% of total bank loans outstanding, compared to 1.84% a year earlier. We continue to maintain what we believe is an appropriate loan loss reserve that was 1.54% of bank loans outstanding at year-end 2012, with our allowance for loan losses at 149.77% of nonperforming bank loans. Now, as always, we remain committed to outstanding asset quality.

We have been in the loan pool participations business since 1988. Loan pool participations are participation interests in performing, sub-performing and non-performing loans that were purchased from various non-affiliated banking organizations and are serviced by a third party. The “all-in” yield on these loan pool participations for 2012 improved to 4.44% from 1.85% in 2011. While 4.44% is not up to the historical yields in this line of business, it does represent the best full year yield since our merger in 2008. We remain committed to exiting this business and the year-end 2012 net balance of $35.7 million now represents only 1.99% of total assets.

Balance sheet metrics remain very strong and we believe that this strength provides us with great flexibility going forward. Year-end tangible common equity was 9.22% of tangible assets at December 31, 2012, up from 8.68% a year earlier. Tier 1 capital was also strong at 9.82% at December 31, 2012. The balance sheet continues to exhibit modest leverage with the bank loans and loan pool participations to deposit ratio at December 31, 2012 standing at 76.7%. This is down from 79.5% at December 31, 2011 and represents continued modest loan demand in our footprint. As we have stated in prior years, our goal is for this metric to be “in the 80's”. With our capital position strong, the Board of Directors increased the quarterly common dividend at its January 15, 2013 meeting, with the first quarter dividend being payable March 15, 2013 to shareholders of record as of March 1, 2013. The new quarterly dividend is $0.125 per share and represents an increase of 47.1% over the rate of our first quarter 2012 dividend.

Critical Accounting Estimates

We have identified the following critical accounting policies and practices relative to the reporting of our results of operations and financial condition. These accounting policies relate to the allowance for loan losses, participation interests in loan pools, intangible assets, and fair value of available for sale investment securities.

Allowance for Loan Losses

The allowance for loan losses is based on our estimate of probable incurred credit losses in our loan portfolio. In evaluating our loan portfolio, we take into consideration numerous factors, including current economic conditions, prior loan loss experience, the composition of the loan portfolio, and management’s estimate of probable credit losses. The allowance for loan losses is established through a provision for loss based on our evaluation of the risk inherent in the loan portfolio, the composition of the portfolio, specific impaired loans, and current economic conditions. Such evaluation, which includes a review of all loans on which full collectability may not be reasonably assured, considers, among other matters, the estimated net realizable value or the fair value of the underlying collateral, economic conditions, historical loss experience, and other factors that warrant recognition in providing for an appropriate allowance for loan losses. In the event that our evaluation of the level of the allowance for loan losses indicates that it is inadequate, we would need to increase our provision for loan losses. We believe the allowance for loan losses as of December 31, 2012, was adequate to absorb probable losses in the existing portfolio.

Participation Interests in Loan Pools

The loan pool accounting practice relates to our estimate that the investment amount reflected on our financial statements does not exceed the estimated net realizable value or the fair value of the underlying collateral securing the purchased loans. In evaluating the purchased loan pool, we take into consideration many factors, including the borrowers’ current financial situation, the underlying collateral, current economic conditions, historical collection experience, and other factors relative to the collection process. If the estimated net realizable value of the loan pool participations were to decline below their carrying amount, our yield on the loan pools would be reduced.

Intangible Assets

Intangible assets arise from purchase business combinations. As a general matter, intangible assets generated from purchase business combinations and deemed to have indefinite lives are not subject to amortization and are instead tested for impairment at least annually. The intangible assets reflected on our financial statements are deposit premium, insurance agency, trade name, and customer list intangibles. The establishment and subsequent amortization, when required by the accounting standards, of these intangible assets involves the use of significant estimates and assumptions. These estimates and assumptions include, among other things, the estimated cost to service deposits acquired, discount rates, estimated attrition rates and useful lives, future economic and market conditions, comparison of our market value to book value and determination of appropriate

34

market comparables. Actual future results may differ from those estimates. We assess these intangible assets for impairment annually or more often if conditions indicate a possible impairment. Each quarter we evaluate the estimated useful lives of intangible assets and whether events or changes in circumstances warrant a revision to the remaining periods of amortization. Recoverability of these assets is measured by comparison of the carrying amount of the asset to the future undiscounted cash flows the asset is expected to generate. If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset.

Fair Value of Available for Sale Securities

Securities available for sale are reported at fair value, with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of deferred income taxes. Declines in fair value of individual securities, below their amortized cost, are evaluated by management to determine whether the decline is temporary or “other-than-temporary.’’ Declines in the fair value of available for sale securities below their cost that are deemed “other-than-temporary” are reflected in earnings as impairment losses. In determining whether other-than-temporary impairment exists, management considers whether: (1) we have the intent to sell the security, (2) it is more likely than not that we will be required to sell the security before recovery of the amortized cost basis, and (3) we do not expect to recover the entire amortized cost basis of the security. When we determine that other-than-temporary-impairment (“OTTI”) has occurred, the amount of the OTTI recognized in earnings depends on whether we intend to sell the security or whether it is more likely than not we will be required to sell the security before recovery of its amortized cost basis. If we intend to sell, or it is more likely than not we will be required to sell, the security before recovery of its amortized cost basis, the OTTI recognized in earnings is equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If we do not intend to sell the security, and it is not more likely than not that we will be required to sell before recovery of its amortized cost basis, the OTTI is separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected, using the original yield as the discount rate, and is recognized in earnings. The amount of the total OTTI related to other factors is recognized in accumulated other comprehensive income (loss), net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. The assessment of whether an OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management at the time.

Results of Operations - Three-Year Period Ended December 31, 2012

Summary

Our consolidated net income and net income available to common shareholders for the year ended December 31, 2012 was $16.8 million, or $1.96 per fully-diluted share, compared to net income of $13.3 million and net income available to common shareholders of $12.7 million, or $1.47 per fully-diluted share, for the year ended December 31, 2011. The increase in consolidated net income was due primarily to an increase in net interest income, after provision for loan losses, of $5.5 million. We also experienced an increase in noninterest income of $5.4 million, mainly due to the $4.0 million gain on the sale of the Home Mortgage Center location realized during the second quarter of 2012. Absent this gain, the increase in noninterest income for the period was $1.3 million, which was primarily due to a $0.9 million increase in mortgage origination and loan servicing fees to $3.6 million, compared with $2.7 million in 2011. Finally, noninterest expense increased to $49.0 million for the year ended December 31, 2012 from $42.2 million for 2011, mainly due to the $6.1 million loss related to the termination and liquidation of the Company's defined benefit pension plan in the second quarter of 2012, recorded in salaries and employee benefits expense. Absent that event, noninterest expense for the period increased $0.6 million, or 1.5%.

The consolidated net income for the year ended December 31, 2011 was $13.3 million. After subtracting preferred stock dividends and discount accretion of $0.6 million, net income available to common shareholders was $12.7 million, or $1.47 per fully-diluted share, compared to net income of $10.1 million and net income available to common shareholders of $9.3 million, or $1.07 per fully-diluted share, for the year ended December 31, 2010. The increase in consolidated net income was due primarily to an increase in net interest income, after provision for loan losses, of $3.5 million. We also experienced a decrease in noninterest income of $0.2 million, mainly due to a decrease in mortgage origination and loan servicing fees of $0.8 million, as such amount declined to $2.7 million in 2011 from $3.5 million in 2010. Finally, decreased noninterest expense provided a $1.1 million positive impact to earnings in 2011 as compared to 2010, primarily due to a $1.2 million decline in FDIC insurance expense.

We ended the year 2012 with an allowance for loan losses of $16.0 million, which represented 149.8% coverage of our nonperforming bank loans (excluding loan pool participations) at December 31, 2012 as compared to 86.6% coverage of our nonperforming bank loans at December 31, 2011 and 76.7% at December 31, 2010. Nonperforming loans totaled $10.7 million as of December 31, 2012 compared with $18.1 million and $19.8 million at December 31, 2011 and December 31, 2010,

35

respectively. For the year ended December 31, 2012, the provision for loan losses decreased to $2.4 million from $3.4 million for 2011, which had decreased from $6.0 million for 2010.

Various operating and equity ratios for the Company are presented in the table below for the years indicated. The dividend payout ratio represents the percentage of our prior year’s net income that is paid to shareholders in the form of cash dividends. Average equity to average assets is a measure of capital adequacy that presents the percentage of average total shareholders’ equity compared to our average assets. The equity to assets ratio is expressed using the period-end amounts instead of an average amount. As of December 31, 2012, under regulatory standards, MidWestOne Bank had capital levels in excess of the minimums necessary to be considered “well capitalized,” which is the highest regulatory designation.

Net Interest Income

Net interest income is the difference between interest income and fees earned on earning assets, less interest expense incurred on interest-bearing liabilities. Interest rate levels and volume fluctuations within earning assets and interest-bearing liabilities impact net interest income. Net interest margin is tax-equivalent net interest income as a percent of average earning assets. 

Certain assets with tax favorable treatment are evaluated on a tax-equivalent basis. Tax-equivalent basis assumes a federal income tax rate of 34%. Tax favorable assets generally have lower contractual pre-tax yields than fully taxable assets. A tax-equivalent analysis is performed by adding the tax savings to the earnings on tax favorable assets. After factoring in the tax favorable effects of these assets, the yields may be more appropriately evaluated against alternative earning assets. In addition to yield, various other risks are factored into the evaluation process.

The following schedule presents the dollar amount of changes in interest income and interest expense for major components of interest-earning assets and interest-bearing liabilities. It distinguishes between the difference related to changes in average outstanding balances and the increase or decrease due to the levels and volatility of interest rates. For each category of interest-earning assets and interest-bearing liabilities information is provided on changes attributable to (i) changes in volume (i.e. changes in volume multiplied by old rate) and (ii) changes in rate (i.e. changes in rate multiplied by old volume). For purposes of this table, changes attributable to both rate and volume that cannot be segregated have been allocated proportionately to the change due to volume and the change due to rate.

Earning Assets, Sources of Funds, and Net Interest Margin

Average earning assets increased $94.2 million, or 6.1%, to $1.6 billion in 2012 as compared to $1.5 billion in 2011. Average earning assets in 2011 increased by $70.3 million, or 4.8%, from 2010. The growth in the average balance of earning assets in 2012 was due primarily to an increase in our portfolio of investment securities of $55.4 million, or 10.9%, and an increase in average loans outstanding of $47.9 million, or 5.0%, somewhat offset by decreases in loan pool participation balances. Growth in the average balance of earning assets in 2011 was due primarily to an increase in our portfolio of investment securities of $91.9 million, or 22.1%, somewhat offset by decreases in loan pool participation balances. Interest-bearing liabilities averaged $1.4 billion for the year ended December 31, 2012, an increase of $60.6 million, or 4.6%, from the average balance for the year ended December 31, 2011. An increase in deposits of $51.0 million plus an increase in borrowed funds of $9.7 million during 2012 accounted for the increase in average interest-bearing liabilities. Interest-bearing liabilities averaged $1.3 billion for the year ended December 31, 2011, an increase of $62.9 million, or 5.0%, from the average balance for the year ended December 31, 2010. An increase in deposits of $59.6 million plus an increase in borrowed funds of $3.3 million during 2011 accounted for the increase in average interest-bearing liabilities from December 31, 2010.

Interest income, on a tax-equivalent basis, increased $1.4 million, or 2.0%, to $72.4 million in 2012 from $71.0 million in 2011. Tax equivalent interest income in 2011 decreased $2.3 million, or 3.1%, to $71.0 million in 2011 from $73.3 million in 2010. Interest income rose in 2012 due primarily to higher volumes in loans and also investment securities, and despite lower yields. In 2011, interest income declined due primarily to lower yields on loan balances and new securities purchased. Our yield on average earning assets was 4.44% in 2012 compared to 4.62% in 2011 and 5.00% in 2010. These declines were due to the historically lower rate environment resulting from the interest rate policy being pursued by the Federal Reserve in response to current economic conditions.

38

Interest expense decreased during 2012 by $3.8 million, or 19.4%, to $16.0 million from $19.8 million in 2011. Interest expense in 2011 decreased by $3.3 million, or 14.4%, from 2010. The decrease in interest expense during 2012 compared to 2011, like that of 2011 compared to 2010, was due to the continued low interest rate environment, and its effect on new liabilities and those repricing during the year. The average rate paid on interest-bearing liabilities was 1.16% in 2012 compared to 1.51% in 2011 and 1.85% in 2010.

Net interest income, on a tax-equivalent basis, increased 10.2% in 2012 to $56.5 million from $51.3 million in 2011. The increased volume of loans and investments during 2012 combined with the lower rates paid on all categories of interest-bearing liabilities, more than offset the lower yields on earning assets and higher volume of interest-bearing liabilities. Tax-equivalent net interest income in 2011 increased by $1.0 million, or 2.1%, from 2010. Net interest margin, which is our net interest income expressed as a percentage of average earning assets stated on a tax-equivalent basis, rose to 3.46% during 2012 compared to 3.34% in 2011 and 3.43% in 2010. The net interest spread, also on a tax-equivalent basis, was 3.28% in 2012 compared to 3.11% in 2011 and 3.15% in 2010. 

Net interest income increased in 2012 as compared to 2011 due primarily to the decrease in interest paid on interest-bearing liabilities combined with the increase in interest received on interest-earning assets. This is partially due to the presence of interest rate floors in portions of our loan portfolio, and the higher volume of loans and investment securities. The increased net interest income for 2011 as compared to 2010 was due primarily to the decrease in interest paid on interest-bearing liabilities exceeding the decrease in interest received on interest-earning assets. This was also partially due to the presence of interest rate floors in portions of our loan portfolio, as well as the higher volume of investment securities relative to 2010. The average balance sheets reflect a competitive marketplace on both the interest-earning assets and interest-bearing deposits. The competition for loans in the marketplace and the overall interest rate environment has kept interest rates on loans low. Interest rates paid on deposit products have declined steadily since 2008, but further significant decline is unlikely as interest rates on deposits have approached zero. We expect to continue battling net interest margin compression in 2013, with interest rates at generational lows.

Provision for Loan Losses

The provision for loan losses is a current charge against income and represents an amount which management believes is sufficient to maintain an adequate allowance for known and probable losses. In assessing the adequacy of the allowance for loan losses, management considers the size, composition, and quality of the loan portfolio measured against prevailing economic conditions, regulatory guidelines, historical loan loss experience and credit quality of the portfolio. When a determination is made by management to write-off a loan balance, such write-off is charged against the allowance for loan losses. 

Our provision for loan losses was $2.4 million during 2012 compared to $3.4 million in 2011 and $6.0 million in 2010. The decrease in provision expense during 2012 was reflective of management’s belief that the allowance for loan losses was adequate based on the inherent risk in the portfolio as of December 31, 2012. During 2012, we added to the allowance for loan losses by maintaining a provision for loan losses that was somewhat greater than our net charge-off activity. The higher level of provision expense during 2011 was reflective of management’s assessment of the then-current risk in the loan portfolio as compared to the allowance for loan losses. During 2010, we added to the allowance for loan losses due primarily to higher charge-offs and increased volatility in our commercial real estate portfolio. The reduction since 2010 in the level of provision expense is indicative of our belief that weak credits have been identified and adequately provided for. See further discussion of the nonperforming loans, under the Nonperforming Assets section.

Total noninterest income rose to $20.1 million, an increase of $5.4 million, or 36.5%, from $14.7 million in 2011. The primary reason for this increase was the $4.0 million gain on the sale of the Home Mortgage Center location realized during the second quarter of 2012. Absent this gain, the increase in noninterest income for the period was $1.3 million, or 9.0%. Mortgage origination and loan servicing fees increased by $0.9 million, or 33.0%, to $3.6 million for 2012, compared to $2.7 million for 2011, due primarily to an increased gains realized on a higher volume of loans originated and sold on the secondary market during 2012 compared to 2011. Trust, investment, and insurance fees increased $0.5 million, or 10.1%, to $5.0 million for 2012, compared with $4.5 million for 2011, due to management concentration of income growth in these areas.

These increases were partially offset by decreased service charges and fees on deposit accounts of $3.2 million for the year ended December 31, 2012, a decline of $0.5 million, or 12.3%, from $3.7 million for 2011. This decline was primarily attributable to lower NSF fees being received between the comparable periods. We expect this decline to stabilize in the coming year, as the regulatory changes resulting in the change will be reflected in both comparable periods. We also experienced a decline in other service charges, commissions and fees to $2.3 million in 2012, down $0.2 million from $2.5 million in 2011. Management’s strategic goal is for noninterest income to constitute 30% of total revenues (net interest income plus noninterest income before gains or losses on sales of securities available for sale and premises and equipment) over time. In 2012, noninterest income comprised 22.0% of total revenues, compared with 22.8% for 2011 and 24.1% for 2010. We expect that increased management focus on growing our insurance agency revenues and increasing the rate of growth in our Trust and Investment Services revenues will reverse this decline going forward.

The decrease in noninterest income for 2011 compared to 2010 was primarily due to the decrease in mortgage origination and servicing fees of $0.8 million, as such amount declined to $2.7 million in 2011 compared to $3.5 million in 2010, and the $0.3 million decrease in service charges and fees on deposit accounts to $3.7 million in 2011 compared to $4.0 million in 2010. These declines were partially offset by increased income from bank-owned life insurance income primarily due to the investment of an additional $8.0 million in insurance policies purchased late in 2010, and decreased losses on the sale of premises and equipment. We also experienced lower losses on the sale of premises and equipment in 2011 compared to 2010.

In 2012 noninterest expense increased $6.7 million, or 15.9%, primarily due to the $6.1 million loss related to the termination and liquidation of the Company's defined benefit pension plan in the second quarter of 2012, recorded in salaries and employee benefits expense. Absent that event, noninterest expense for the year increased $0.6 million, or 1.5%. Excluding the pension loss, salaries and employee benefits increased $1.4 million, or 6.0%, primarily due to annual salary and benefit rate increases for employees that were effective at the beginning of 2012. Full-time equivalent employee levels were 390, 383 and 383 at December 31, 2012, 2011 and 2010, respectively.

This increase was partially offset by a decrease in FDIC insurance expense of $0.4 million, or 24.1%, to $1.2 million for the year of 2012, compared with $1.6 million for 2011. Net occupancy and equipment also experienced a decline of $0.3 million, or 4.5%, to $6.2 million for 2012, compared with $6.5 million for 2011, due to management’s continued efficiency efforts. Professional fees were virtually unchanged for 2012 compared to 2011, as were data processing expenses, and other operating expenses.

Noninterest expense decreased $1.1 million, or 2.4%, for 2011 compared with 2010, primarily due to a decrease in FDIC insurance expense of $1.2 million. The decrease was due primarily to lower assessment rates by the FDIC. This decrease was partially offset by a $0.3 million increase in other operating expenses. Salary and employee benefit expense was virtually unchanged for 2011 from 2010, as was net occupancy and equipment expense. Professional fees increased $0.1 million for 2011 due to generally higher costs associated with outside professional services we utilize.

Income Tax Expense

Our effective tax rate, or income taxes divided by income before taxes, was 24.2% for 2012 compared with 25.7% for 2011. The lower effective rate in 2012 was primarily due to changes in the levels of taxable income, increased investment in tax-free municipal securities, and realization of a $0.2 million tax benefit from the partial release of a valuation allowance on capital losses during the second quarter of 2012. Income tax expense increased by $0.7 million to $5.3 million in 2012 compared to tax expense of $4.6 million for 2011 due to increased taxable income.

Income taxes increased by $1.2 million for 2011 compared with 2010 due to increased taxable income and the relative amount of income from our investments in tax-favored securities and bank-owned life insurance. Our consolidated income tax rate varies from the statutory rate mainly due to the amount of tax-exempt income. The effective income tax rate as a percentage of income before tax was 25.7% for 2011, compared with 25.1% for 2010.

Financial Condition - December 31, 2012 and 2011

Summary

Our total assets increased $97.6 million, or 5.8%, to $1.8 billion as of December 31, 2012 from $1.7 billion as of December 31, 2011. This growth resulted primarily from increased investment in securities of $54.1 million, and an increase in bank portfolio loans of $49.1 million. Increased funding from deposits and securities sold under agreement to repurchase combined with the reduction of loan pool participations provided additional liquidity. Loan pool participations, net, were $35.7 million at December 31, 2012 compared to $50.1 million at December 31, 2011, a decrease of $14.4 million, or 28.8%, due to loan charge-offs and normal loan repayments. As previously discussed, we intend to exit this line of business as current balances pay down and concentrate on our our core community banking business. Our loan-to-deposit ratio, including loan pool participations,

41

decreased to 76.7% at year-end 2012 compared to 79.5% at year-end 2011, with our target range being between 80% and 90%. The decline in this ratio is reflective of the ready availability of deposits in our footprint, and the modest demand for loans. While we continue to focus on quality loan growth, the continuing influx of deposits will make reaching our target range difficult in the near future.

Total liabilities increased by $80.1 million from December 31, 2011 to December 31, 2012. Our deposits increased $93.1 million, or 7.1%, to $1.4 billion as of December 31, 2012 from $1.3 billion at December 31, 2011. The increase in deposits was primarily due to organic growth in business and individual, partnership and non-profit deposits, primarily in both interest-bearing and non-interest-bearing checking products. Brokered CDs obtained through participation in the Certificate of Deposit Account Registry Service (“CDARS”) program decreased by $6.4 million in 2012 to $22.4 million, while brokered business money market accounts obtained through participation in the Insured Cash Sweeps (“ICS”) program increased by $0.8 million to $20.8 million. We have an internal policy limit on brokered deposits of not more than 10% of our total assets. At December 31, 2012 brokered deposits were 2.7% of our total liabilities. FHLB borrowings were $120.1 million at December 31, 2012 compared to $140.0 million at December 31, 2011, a decrease of $19.9 million, or 14.2%. Other liabilities decreased $4.5 million or 31.8%, due primarily to $3.0 million less in unsettled purchases of investment securities.

Shareholders’ equity increased by $17.4 million, primarily due to 2012 net income of $16.8 million.

Investment Securities

Our investment securities portfolio is managed to provide both a source of liquidity and earnings. Our portfolio totaled $590.2 million at December 31, 2012 compared to $536.1 million at December 31, 2011. The increase was due primarily to the investment of increased liquidity generated by deposit and repurchase agreement growth and reduced loan pool participation balances during 2012. Our loan activity is discussed more fully in the Loans section and loan pool participation activity is discussed in the Loan Pool Participations section, while our deposit growth is discussed more fully in the Deposits section.

Securities available for sale are carried at fair value. As of December 31, 2012, the fair value of our securities available for sale was $557.5 million and the amortized cost was $539.3 million. There were $19.8 million of gross unrealized gains and $1.5 million of gross unrealized losses in our investment securities available for sale portfolio for a net unrealized gain of $18.3 million. The after-tax effect of this unrealized gain has been included in shareholders’ equity. The ratio of the fair value as a percentage of amortized cost was virtually unchanged from December 31, 2011, due to the continued stability in overall interest rates during 2012, resulting in almost no change in the relative value of our debt-related securities.

U.S. government and agency securities as a percentage of total securities increased to 12.5% at December 31, 2012, from 10.6% at December 31, 2011, while obligations of state and political subdivisions (primarily tax-exempt obligations) as a percentage of total securities decreased to 39.1% at December 31, 2012, from 41.1% at December 31, 2011. Investments in mortgage-backed securities decreased to 43.6% of total securities at December 31, 2012, as compared to 45.7% of total securities at December 31, 2011. The receipt of principal, at par, and interest on mortgage-backed securities is guaranteed by the respective government-sponsored agency guarantor, such that the Company believes that its mortgage-backed securities do not expose the Company to credit-related losses. The Company's mortgage-backed securities portfolio consisted of securities predominantly underwritten to

42

the standards of and guaranteed by the government-sponsored agencies of FHLMC, FNMA and GNMA. We consider many factors in determining the composition of our investment portfolio including tax-equivalent yield, credit quality, duration, expected cash flows and prepayment risk, as well as the liquidity position and the interest rate risk profile of the Bank.

Our investment portfolio includes an investment in collateralized debt obligations that are backed by trust preferred securities issued by banks, thrifts and insurance companies. These six securities had an original cost of $9.8 million, but due to several impairment charges recognized during 2010, 2009 and 2008, the book value of these securities at December 31, 2012, had been reduced to $1.8 million. Two of the securities have been written down to a value of zero, with the remaining four having an average book value of 18.2% of their original face value. The market for these securities at December 31, 2012 was not active and markets for similar securities are also not active. The valuation of these securities involves an assessment of the financial strength of the individual institutions that comprise the collateral for the bonds. Future default probabilities are assigned based on these measurements of financial strength. Other factors in the valuation include contractual terms of the cash flow waterfall (for both interest and principal), collateralization testing and events of default/liquidation. Based on our cash flow analysis, we have determined that not all contractual cash flows will be received; however, no additional other-than-temporary impairment charges were recorded during 2012 or 2011. Any future decline in the collateral performance of our pooled trust preferred debt obligations could result in additional other-than-temporary impairment charges.

Our loan portfolio, before allowance for loan losses, increased 5.0% to $1.0 billion as of December 31, 2012 from $986.2 million at December 31, 2011. A significant portion of the overall loan increase occurred in one- to four- family first liens, which increased $22.3 million, or 12.7%, to $197.7 million as of December 31, 2012, from $175.4 million at December 31, 2011. This growth was primarily due to our strategic decision to retain up to $20.0 million of fixed rate loans originated with a maturity of 15 years or less in our own portfolio. Construction and development loans increased $13.5 million, or 18.5%, to $86.8 million as of December 31, 2012, compared to $73.3 million at December 31, 2011. This increase was primarily the result of the funding of two healthcare industry construction projects in our market. We expect this trend to continue once construction begins on two new assisted living projects in 2013. Multifamily real estate loans also increased to $47.8 million as of December 31, 2012, from $34.7 million at December 31, 2011, a change of $13.0 million, or 37.6%. The refinance from outside the Company of a property in our Iowa City market was the primary reason for this increase. Commitments under standby letters of credit, unused lines of credit and other conditionally approved credit lines, totaled approximately $293.0 million and $206.6 million as of December 31, 2012 and 2011, respectively.

Even with the blend of significant agricultural, manufacturing, academia and healthcare industries prevalent in our markets, we experienced sporadic demand for new non-real-estate debt in recent years. This trend, which we understand to be widespread in the United States, appears to be driven by depressed consumer confidence leading to a generally lower demand for debt financed purchases. Although we maintained prudent underwriting standards in 2012, when presented with opportunities to fund quality loans, we readily acted to assist our customers and communities. Nonetheless, our loan to deposit ratio decreased to 76.7% at year end 2012 from 79.5% at the end of 2011. The decline in this ratio is reflective of the ready availability of deposits in our footprint, and the modest demand for loans. While we continue to focus on quality loan growth, the continuing influx of deposits will make reaching our target range of “in the 80’s” difficult in the near future.

The loan portfolio includes a concentration of loans for commercial real estate, which are included in the table above, amounting to approximately $440.0 million and $396.0 million as of December 31, 2012 and 2011, respectively. Of this amount, $81.1 million, or 7.8%, was secured by farmland at December 31, 2012, compared to $74.5 million, or 7.6%, at December 31, 2011. Generally, these loans are collateralized by assets of the borrowers and are expected to be repaid from cash flows or from proceeds from the sale of selected assets of the borrowers.

Of the $373.5 million of variable rate loans, approximately $226.4 million, or 60.6%, are subject to interest rate floors, with a weighted average floor rate of 4.70%.

Nonperforming Assets

It is management’s policy to place loans on nonaccrual status when interest or principal is 90 days or more past due. Such loans may continue on accrual status only if they are both well-secured and in the process of collection.

We experienced a decrease in total nonperforming assets during 2012 as compared to 2011. Total nonperforming assets were $13.9 million at December 31, 2012, compared to $22.1 million at December 31, 2011, a $8.2 million, or 37.1%, decrease. Nonperforming loans decreased $7.5 million during 2012, with a $0.7 million decrease in nonperforming other assets (other real estate owned). The largest category of nonperforming loans was commercial real estate loans, with a balance of $3.8 million at December 31, 2012. The remaining nonperforming loans consisted of $3.4 million in agricultural, $1.8 million in commercial and industrial, and $1.6 million in residential real estate loans. The decrease in other real estate owned (“OREO”) was primarily attributable to decreases in commercial real estate properties to $3.2 million at December 31, 2012 compared to $3.6 million at December 31, 2011, while single family residential OREO decreased to $0.1 million from $0.4 million for the same respective periods.

Nonperforming loans decreased from $18.1 million, or 1.84% of total bank loans at December 31, 2011, to $10.7 million, or 1.03% of total bank loans at December 31, 2012. At December 31, 2012, nonperforming loans consisted of $2.9 million in nonaccrual loans, $7.1 million in troubled debt restructures and $0.6 million in loans past due 90 days or more and still accruing. This compares to nonaccrual loans of $10.9 million, troubled debt restructures of $6.1 million, and loans past due 90 days or more and still accruing of $1.1 million at December 31, 2011. The decrease in nonperforming loans is primarily due to the payoff of two agricultural credits totaling $1.8 million, the pay-down of a development loan of $1.1 million, and the reduction of 15 residential real estate loans totaling $1.5 million, all of which had been on nonaccrual. The change in troubled debt restructure is primarily attributable to the movement of a $1.0 million commercial real estate credit out of troubled debt restructure due to continued positive performance, combined with a $2.5 million nonaccrual farmland credit being reclassified as a troubled debt restructure due to a court ordered interest rate reduction in connection with a Chapter 12 bankruptcy. Bank loans past due 30 to 89 days and still accruing interest (not included in the nonperforming loan totals) were $6.1 million at December 31, 2012, compared with $7.0 million at December 31, 2011. At December 31, 2012, other real estate owned (not included in nonperforming loans) was $3.3 million, down from $4.0 million at December 31, 2011. The allowance for loan losses represented 149.77% of nonperforming loans at December 31, 2012, compared with 86.58% of nonperforming loans at December 31, 2011.

A loan is considered to be impaired when, based on current information and events, it is probable that we will not be able to collect all amounts due. The accrual of interest income on impaired loans is discontinued when there is reasonable doubt as to the borrower’s ability to meet contractual payments of interest or principal. Interest income on these loans is recognized to the extent interest payments are received and the principal is considered fully collectible.

The gross interest income that would have been recorded in the years ended December 31, 2012, 2011 and 2010 if the nonaccrual and troubled debt restructure loans had been current in accordance with their original terms was $2.2 million, $1.6 million, and $1.9 million, respectively. The amount of interest collected on those loans that was included in interest income was $0.8 million, $0.4 million, and $0.5 million for the years ended December 31, 2012, 2011 and 2010, respectively.

In addition to the non-performing and past due loans mentioned above, the Company also has identified loans for which management has concerns about the ability of the borrowers to meet existing repayment terms. The loans are generally secured by either real estate or other borrower assets, reducing the potential for loss should they become non-performing. Although these loans are generally identified as potential problem loans, it is possible that they never become non-performing. Such loans totaled $2.2 million at December 31, 2012.

Loan Review and Classification Process for Agricultural Loans, Commercial and Industrial Loans, and Commercial Real Estate Loans

The Company maintains a loan review and classification process which involves multiple officers of the Company and is designed to assess the general quality of credit underwriting and to promote early identification of potential problem loans. All commercial and agricultural loan officers are charged with the responsibility of risk rating all loans in their portfolios and updating the ratings, positively or negatively, on an ongoing basis as conditions warrant. A monthly loan officer validation worksheet documents this process. Risk ratings are selected from an 8-point scale with ratings as follows: ratings 1- 4 Satisfactory (pass), rating 5 Watch (potential weakness), rating 6 Substandard (well-defined weakness), rating 7 Doubtful, and rating 8 Loss.

When a loan officer originates a new loan, based upon proper loan authorization, he or she documents the credit file with an offering sheet summary, supplemental underwriting analysis, relevant financial information and collateral evaluations. All of this information is used in the determination of the initial loan risk rating. The Company's loan review department undertakes independent credit reviews of relationships based on either criteria established by loan policy, risk-focused sampling, or random sampling. Loan policy requires the top 50 lending relationships by total exposure as well as all classified and Watch rated credits over $250,000 be reviewed no less than annually. The individual loan reviews consider such items as: loan type; nature, type and estimated value of collateral; borrower and/or guarantor estimated financial strength; most recently available financial information; related loans and total borrower exposure; and current/anticipated performance of the loan. The results of such reviews are presented to executive management.

Through the review of delinquency reports, updated financial statements or other relevant information, the lending officer and/or loan review personnel may determine that a loan relationship has weakened to the point that a criticized (loan grade 5) or classified (loan grade 6 through 8) status is warranted. When a loan relationship with total related exposure of $1.0 million or greater is adversely graded (5 or above), or is classified as a troubled debt restructure (regardless of size), the lending officer is then charged with preparing a loan strategy summary worksheet that outlines the background of the credit problem, current repayment status of the loans, current collateral evaluation and a workout plan of action. This plan may include goals to improve the credit rating, assisting the borrower in moving the loans to another institution and/or collateral liquidation. All such reports are first presented to regional management and then to the board of directors by the Executive Vice President, Chief Credit Officer (or a designee).

Depending upon the individual facts and circumstances and the result of the Classified/Watch review process, loan officers and/or loan review personnel may categorize the loan relationship as impaired. Once that determination has occurred, the loan officer, in conjunction with regional management, will complete an evaluation of the collateral (for collateral-dependent loans) based upon appraisals on file adjusting for current market conditions and other local factors that may affect collateral value. Loan review personnel may also complete an independent impairment analysis when deemed necessary. These judgmental evaluations may produce an initial specific allowance for placement in the Company's allowance for loan & lease losses calculation. As soon as practical, updated appraisals on the collateral backing that impaired loan relationship are ordered. When the updated appraisals are received, regional management, with assistance from the loan review department, reviews the appraisal and updates the specific allowance analysis for each loan relationship accordingly. The board of directors on a quarterly basis reviews the Classified/Watch reports including changes in credit grades of 5 or higher as well as all impaired loans, the related allowances and OREO.

In general, once the specific allowance has been finalized, regional and executive management will consider a charge-off prior to the calendar quarter-end in which that reserve calculation is finalized.

The review process also provides for the upgrade of loans that show improvement since the last review.

Restructured Loans

We restructure loans for our customers who appear to be able to meet the terms of their loan over the long term, but who may be unable to meet the terms of the loan in the near term due to individual circumstances. We consider the customer's past performance, previous and current credit history, the individual circumstances surrounding the current difficulties and their plan to meet the terms of the loan in the future prior to restructuring the terms of the loan. All of the following factors are indicators that the Bank has granted a concession (one or multiple items may be present):

• The borrower receives a reduction of the stated interest rate for the remaining original life of the debt.

• The borrower receives an extension of the maturity date or dates at a stated interest rate lower than the current market interest rate for new debt with similar risk characteristics.

• The borrower receives a reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement.

• The borrower receives a deferral of required payments (principal and/or interest).

• The borrower receives a reduction of the accrued interest.

Generally, loans are restructured through short-term interest rate relief, short-term principal payment relief or short-term principal and interest payment relief. Once a restructured loan has gone 90 days or more past due or is placed on nonaccrual status, it is included in the 90+ day past due or nonaccrual totals in the previous table.

During the year ended December 31, 2012 four loans were classified as new troubled debt restructures (“TDR”). One commercial and industrial loan was added to the TDR loan classification due to being extended and re-amortized to a longer period. This credit also experienced a payment default during 2012. Two farmland loans, both to the same borrower, were classified as new TDRs during 2012 due to a court ordered interest rate reduction in connection with a Chapter 12 bankruptcy. One one- to four- family junior lien was granted a rate concession due to borrower financial difficulties during 2012.

During the year ended December 31, 2011 nine loans were classified as new TDRs. One commercial and industrial loan was added to the TDR loan classification due to a partial charge-off of its outstanding principal and an adjustment to its terms granting a below market interest rate. Likewise, a construction and development loan was also added due to a partial balance charge-off and interest rate concession. Four commercial real estate loans, all to the same borrower, were classified as new TDRs during 2011 due to the extension of a forbearance agreement and the granting of a below market interest rate. These four credits also experienced a payment default during 2011. One commercial real estate loan that was a new TDR during 2011 due to a below market interest rate was on non-accrual at year-end. One- to four- family first lien restructures increased by one loan due to an interest rate concession. A commercial real estate loan TDR that was on non-accrual at December 31, 2010, was rewritten with a rate concession and had additional funds advanced in 2011, and was reported as a new TDR. During 2011, one restructured consumer loan that had been on non-accrual at year-end 2010 returned to accrual status. In addition, a commercial and industrial loan moved from being a performing TDR at December 31, 2010 to non-accruing at year-end 2011.

We consider all TDRs, regardless of whether they are performing in accordance with the modified terms, to be impaired loans when determining our allowance for loan losses. A summary of restructured loans as of December 31, 2012 and December 31, 2011 is as follows:

This table indicates marginal growth in the allowance for loan losses as of December 31, 2012, as compared to December 31, 2011. The table also indicates significant growth in the allowance for loan losses in commercial real estate and commercial and industrial categories as of December 31, 2009, as compared to December 31, 2008. This increase was due primarily to the allocation of the $5.5 million of the allowance for loan losses shown as acquired from the Former MidWestOne at December 31, 2008, into the appropriate loan classes, causing the increases in those specific categories. The overall increase of $3.0 million, or 27% in 2009, reflects our increased provision for loan losses.

During the first quarter of 2012 we changed the historical charge-off component of the ALLL calculation from a five-year annual average to a rolling 20-quarter annual average. The historical charge-off portion is one of several factors used in establishing our reserve level for each loan type. We also enhanced our method for determining the loan type categories that individual loans are included in for ALLL purposes, which provides a more granular basis for computing the ALLL. Finally, all credit relationships with a balance less than $200,000 are now evaluated for ALLL adequacy purposes based solely on delinquency status, unless the loan has been placed on nonaccrual or is classified as a TDR. In the second quarter of 2012 we enhanced our ALLL methodology for credit relationships below $200,000 that are 60-89 days past due to better reflect the risk inherent in loans at this level of delinquency.  The loss allocation for these credits was increased to 25% of the historical loss given default for the respective loan categories. During the third quarter of 2012 we further enhanced our calculation methodology by expanding the number of qualitative factors used to calculate the ALLL from three to nine. This change will provide additional strength to and support for our process. There were no other changes to our ALLL calculation during the year of 2012, and these changes did not have a material impact on the allowance. Classified and impaired loans are reviewed per the requirements of FASB ASC Topic 310.

We currently track the loan to value (“LTV”) ratio of loans in our portfolio, and those loans in excess of internal and supervisory guidelines are presented to the Bank’s board of directors on a quarterly basis. At December 31, 2012, there were eight owner-occupied 1-4 family loans with a LTV of 100% or greater. In addition, there were 35 home equity loans without credit enhancement that had LTV of 100% or greater. We have the first lien on 12 of these equity loans and other financial institutions have the first lien on the remaining 23.

We review all impaired and nonperforming loans individually on a quarterly basis to determine their level of impairment due to collateral deficiency or insufficient cash-flow based on a discounted cash-flow analysis. At December 31, 2012, reported TDRs were not a material portion of the loan portfolio. We review loans 90+ days past due that are still accruing interest no less than quarterly to determine if there is a strong reason that the credit should not be placed on non-accrual.

Loan Pool Participations

As of December 31, 2012, we had loan pool participations of $35.7 million compared to $50.1 million at December 31, 2011, both net of an allowance for loan losses of $2.1 million. Loan pools are participation interests in performing, subperforming and nonperforming loans that have been purchased from various nonaffiliated banking organizations. The Former MidWestOne had engaged in this activity since 1988. The loan pool investment balance shown as an asset on our consolidated balance sheets represents the discounted purchase cost of the loan pool participations, net of the related allowance for loan losses. After extensive discussion and analysis of our current loan pool portfolio during 2010, we decided to exit this line of business as current balances

pay down. As such, we did not acquire any new loan pool participations during 2012. As of December 31, 2012, the categories of loans by collateral type in the loan pool participations were commercial real estate - 64.4%, commercial and industrial loans - 6.3%, single-family residential real estate - 12.7% and other loans - 16.6%. We have minimal exposure in loan pool participations to consumer real estate, subprime credit or to construction and real estate development loans.

The net “all-in” yield (excluding purchase accounting adjustments and after all expenses) on loan pool participations was 4.44% and 1.85% for the years ended December 31, 2012 and 2011, respectively. The net yield was higher in 2012 than for 2011 primarily due to the sale of several foreclosed real estate properties in the portfolio at a value greater than their net book value, a trend we do not expect to continue in the future, despite recent results. We expect overall lower rates of return on the loan pool participations to continue in the future, as the percentage of performing credits in the portfolio continues to decrease.

The loans in the pools provide some geographic diversification to our balance sheet. As of December 31, 2012, loans in the southeast region of the United States represented approximately 41.4% of the total. The northeast region region was the next largest area with 30.6%, the central with 22.6%, followed by the southwest region with 4.7% and the northwest with 0.7%. The highest concentration of assets in any one state is Florida at approximately 24.1% of the basis total, with the next highest state level being Ohio at 14.4%, followed by New Jersey at 9.9%. As of December 31, 2012, approximately 64.5% of the loans were contractually current or less than 90 days past due, while 35.5% were contractually past due 90 days or more. It should be noted that many of the loans were acquired in a contractually past due status, which is reflected in the discounted purchase price of the loans. Performance status is monitored on a monthly basis. The 35.5% contractually past due total includes loans in litigation and foreclosed property. As of December 31, 2012 and 2011, loans in litigation totaled approximately $3.6 million and $6.1 million respectively, while foreclosed property was approximately $6.1 million and $12.0 million, respectively. As of December 31, 2012, our investment basis in loan pool participations was approximately 35.9% of the face amount of the underlying loans, compared to approximately 40.6% at December 31, 2011.

Intangible Assets

Intangible assets totaled $9.5 million and $10.2 million at December 31, 2012 and 2011, respectively. Intangible assets declined during the year ended December 31, 2012 by $0.7 million, primarily related to core deposit amortization during the year. We recorded $0.1 million of goodwill impairment charges in 2011, which represented all of the goodwill related to our insurance subsidiary, and no impairment charges during 2012 or 2010 related to our other intangible assets. This action was taken upon comparison of the subsidiary’s recent operating performance to that anticipated when we purchased the Butler-Brown insurance agency in Oskaloosa, Iowa, in December 2008.

Deposits

As indicated in the following table, the average balances of the interest-bearing demand deposit category as a percentage of average total deposits showed steady growth for the year ended December 31, 2012 compared to the years ended December 31, 2011, and December 31, 2010.

Non-interest-bearing accounts increased $21.8 million from year-end 2011 to December 31, 2012, of which $5.9 million was in public funds and $11.9 million was in commercial accounts. Interest-bearing demand deposits increased $51.0 million.  Of that increase, $14.6 million was in our Power Checking product, $11.6 million was in business money market accounts, and $10.7 million, was in personal money market accounts.  Personal savings accounts increased by $7.9 million. The aggregate balance of time deposits declined by $9.2 million from 2011 to 2012, primarily in deposits less than $100,000.

Off-Balance Sheet Transactions

During the normal course of business, we become a party to financial instruments with off-balance sheet risk in order to meet the financing needs of our customers. These financial instruments include commitments to make loans and open-ended revolving lines of credit. We follow the same credit policy (including requiring collateral, if deemed appropriate) to make such commitments as is followed for those loans that are recorded in our financial statements.

Our exposure to credit losses in the event of nonperformance is represented by the contractual amount of the commitments. Management does not expect any significant losses as a result of these commitments. Off-balance sheet transactions are more fully discussed in Note 16 to our consolidated financial statements.

The following table summarizes our off-balance sheet commitments by expiration period, as of December 31, 2012:

Capital Resources

The Federal Reserve Board uses capital adequacy guidelines in its examination and regulation of bank holding companies and their subsidiary banks. Risk-based capital ratios are established by allocating assets and certain off-balance sheet commitments into four risk-weighted categories. These balances are then multiplied by the factor appropriate for that risk-weighted category. The guidelines require bank holding companies and their subsidiary banks to maintain a total capital to total risk-weighted asset ratio of not less than 8.00%, of which at least one half must be Tier 1 capital, and a Tier 1 leverage ratio of not less than 4.00%. As of December 31, 2012, MidWestOne Financial Group, Inc. had a total capital to total risk-weighted asset ratio of 14.03%, a Tier 1 capital to risk-weighted asset ratio of 12.78% and a Tier 1 leverage ratio of 9.82%; MidWestOne Bank had ratios of 12.77%, 11.52%, and 8.83%, respectively. MidWestOne Bank exceeds the regulatory capital guidelines necessary to be considered well-capitalized.

On July 6, 2011, the Company completed the redemption of the 16,000 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A, which had been issued to the U.S. Department of the Treasury (”Treasury”) under the Capital Purchase Program, for a total of $16.1 million, consisting of $16.0 million of principal and $0.1 million of accrued and unpaid dividends. On July 27, 2011, the Company also repurchased for $1.0 million, the common stock warrant it had issued to Treasury. The warrant had allowed Treasury to purchase 198,675 shares of MidWestOne common stock at $12.08 per share. Although these transactions resulted in a decrease in the Company’s capital level, management and our board of directors view our ability to exit TARP without conducting a dilutive capital raise as a significant positive for our shareholders.

54

On January 15, 2013, the Company's board of directors announced the renewal of the Company's share repurchase program, extending the expiration of the program to December 31, 2014 and increasing the remaining amount of authorized repurchases under the program to $5.0 million from the approximately $2.4 million of authorized repurchases that had remained at December 31, 2012. Pursuant to the program, the Company may repurchase shares from time to time in the open market, and the method, timing and amounts of repurchase will be solely in the discretion of the Company's management. The repurchase program does not require the Company to acquire a specific number of shares. Therefore, the amount of shares repurchased pursuant to the program will depend on several factors, including market conditions, capital and liquidity requirements, and alternative uses for cash available. For the year of 2012 we repurchased a total of 104,518 shares of common stock at a cost of $1.8 million.

During 2012, 55,986 shares were issued in connection with the exercise of previously issued stock options, and 15,268 shares were surrendered in connection with the exercise of such options. On January 17, 2012, 22,232 restricted stock units were granted to certain directors and officers. During 2012, 15,810 shares were issued in connection with the vesting of previously awarded grants of restricted stock units, of which 1,052 shares were surrendered by grantees to satisfy tax requirements.

On February 15, 2013, we renewed a universal shelf-registration statement registering for future sale of up to $25.0 million of securities from time to time in one or more offerings. Given the potential growth opportunities available and the difficult credit market currently facing financial institutions, we believe that it is prudent to have all options available to raise additional capital. Difficult economic conditions present both challenges and opportunities. Thus, we have positioned ourselves to raise additional capital in an efficient manner for both organic and external growth opportunities if such opportunities arise.

Liquidity

Liquidity management involves the ability to meet the cash flow requirements of depositors and borrowers. We conduct liquidity management on both a daily and long-term basis. We adjusted our investments in liquid assets based upon management’s assessment of expected loan demand, projected loan sales, expected deposit flows, yields available on interest-bearing deposits, and the objectives of our asset/liability management program. Excess liquidity is invested generally in short-term U.S. government and agency securities, short and medium-term state and political subdivision securities, and other investment securities.

Our most liquid assets are cash and due from banks, interest-bearing bank deposits, and federal funds sold. The balances of these assets are dependent on our operating, investing, lending, and financing activities during any given period. 

Liquid assets on hand are summarized in the table below:

	Years Ended December 31,
	2012			2011			2010
	Balance			Balance			Balance
(dollars in thousands)
Cash and due from banks	$	30,197		$	28,155		$	13,720
Interest-bearing deposits	16,242			4,468			6,077
Federal funds sold	752			—			726
Total	$	47,191		$	32,623		$	20,523
Percentage of average total assets	2.7		%	2.0		%	1.3		%

Our principal sources of funds are deposits, advances from the FHLB, principal repayments on loans, proceeds from the sale of loans, proceeds from the maturity and sale of investment securities, our Federal Funds lines of credit, and funds provided by operations. While scheduled loan amortization and maturing interest-bearing deposits are relatively predictable sources of funds, deposit flows and loan prepayments are greatly influenced by economic conditions, the general level of interest rates, and competition. We utilized particular sources of funds based on comparative costs and availability. This included fixed-rate advances from the FHLB that were obtained at a more favorable cost than deposits. We generally managed the pricing of our deposits to maintain a steady deposit base but from time to time decided not to pay rates on deposits as high as our competition.

As of December 31, 2012, we had $15.5 million of long-term debt outstanding. This amount represents indebtedness payable under junior subordinated debentures issued to a subsidiary trust that issued trust preferred securities in a pooled offering. The junior subordinated debentures have a 35-year term. One-half of the balance had a fixed interest rate of 6.48% until December 15, 2012, while the other one-half had a variable rate of three-month LIBOR plus 1.59%. On December 15, 2012, the entire balance became variable rate, tied to the three-month LIBOR plus 1.59%. At December 31, 2012 the interest rate was 1.90%.

55

Net cash provided by operations was another major source of liquidity. The net cash provided by operating activities was $22.5 million for the year ended December 31, 2012 and $23.7 million for the year ended December 31, 2011.

As of December 31, 2012, we had outstanding commitments to extend credit to borrowers of $287.2 million, standby letters of credit of $4.6 million, and commitments to sell loans of $1.2 million. Certificates of deposit maturing in one year or less totaled $349.4 million as of December 31, 2012. We believe that a significant portion of these deposits will remain with us upon maturity.

Inflation

The effects of price changes and inflation can vary substantially for most financial institutions. While management believes that inflation affects the growth of total assets, it is difficult to assess the overall impact. Management believes this to be the case due to the fact that generally neither the timing nor the magnitude of the inflationary changes in the consumer price index (“CPI”) coincide with changes in interest rates. The price of one or more of the components of the CPI may fluctuate considerably and thereby influence the overall CPI without having a corresponding effect on interest rates or upon the cost of those goods and services normally purchased by us. In years of high inflation and high interest rates, intermediate and long-term interest rates tend to increase, thereby adversely impacting the market values of investment securities, mortgage loans and other long-term fixed rate loans held by financial institutions. In addition, higher short-term interest rates caused by inflation tend to increase financial institutions’ cost of funds. In other years, the reverse situation may occur.

Recent Accounting Pronouncements

In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, which changed the wording used to describe many of the requirements in U.S. generally accepted accounting principles (“GAAP”) for measuring fair value and for disclosing information about fair value measurements. For many of the requirements, the FASB did not intend for the amendments to result in a change in the application of the requirements in Topic 820. Some of the amendments clarified the FASB’s intent about the application of existing fair value measurement requirements, while other amendments changed a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. The amendments in this update were to be applied prospectively, and early application by public entities was not permitted. For public entities, the amendments were effective during interim and annual periods beginning after December 15, 2011. The Company adopted this guidance effective January 1, 2012, and the adoption did not have a material effect on the Company’s consolidated financial statements.

In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. The objective of this update is to improve the comparability, consistency, and transparency of financial reporting and to increase the prominence of items reported in other comprehensive income. To increase the prominence of items reported in other comprehensive income and to facilitate convergence of U.S. GAAP and International Financial Reporting Standards (“IFRS”), the FASB decided to eliminate the option to present components of other comprehensive income as part of the statement of changes in shareholders’ equity, among other amendments in this update. The amendments require that all nonowner changes in shareholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments in this update are to be applied retrospectively, with early adoption permitted. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of this amendment did not have a material effect on the Company’s consolidated financial statements.

In December 2011, the FASB issued Accounting Standards Update No. 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05. Update 2011-12 defers those changes outlined in Update 2011-05 that relate to how and where reclassification adjustments are presented. While the FASB is considering the operational concerns about the presentation requirements for classification adjustments, entities will continue to report reclassifications out of accumulated comprehensive income consistent with the presentation requirements in effect before Update 2011-05. The amendments are effective at the same time as the amendments in Update 2011-05, and did not have a material effect on the Company’s consolidated financial statements.

In July 2012, the FASB issued Accounting Standards Update No. 2012-02, Intangibles—Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. This update permits an entity to make a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset, other than goodwill, is impaired. Currently, entities are required to quantitatively test indefinite-lived intangible assets for impairment at least annually and more frequently if indicators of impairment exist. Under this update, if an entity concludes, based on an evaluation of all relevant qualitative factors, that it is not more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, it will not be required to perform the quantitative impairment test for that asset. The update is effective for annual and interim

56

impairment tests performed for fiscal years beginning after September 15, 2012 and is not expected to have a material impact on the Company’s consolidated financial statements.

In February 2013, the FASB issued Accounting Standards Update No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This update seeks to to improve the reporting of reclassifications out of accumulated other comprehensive income by requiring an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income, if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. This would be the case when a portion of the amount reclassified out of accumulated other comprehensive income is reclassified to a balance sheet account (for example, inventory) instead of directly to income or expense in the same reporting period. For public entities, the amendments are effective prospectively for reporting periods beginning after December 15, 2012. The adoption of this amendment is not expected to have a material effect on the Company’s consolidated financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

In general, market risk is the risk of change in asset values due to movements in underlying market rates and prices. Interest rate risk is the risk to earnings and capital arising from movements in interest rates. Interest rate risk is the most significant market risk affecting us as other types of market risk, such as foreign currency exchange rate risk and commodity price risk, do not arise in the normal course of our business activities.

In addition to interest rate risk, recent economic conditions have made liquidity risk (namely, funding liquidity risk) a more prevalent concern among financial institutions. In general, liquidity risk is the risk of being unable to fund an entity’s obligations to creditors (including, in the case of banks, obligations to depositors) as such obligations become due and/or fund its acquisition of assets.

57

Liquidity Risk

Liquidity refers to our ability to fund operations, to meet depositor withdrawals, to provide for our customers’ credit needs, and to meet maturing obligations and existing commitments. Our liquidity principally depends on cash flows from operating activities, investment in and maturity of assets, changes in balances of deposits and borrowings, and our ability to borrow funds.

Net cash provided by operating activities was $22.5 million during 2012, compared with $23.7 million in 2011 and $20.5 million in 2010. Proceeds from loans held for sale, net of funds used to originate loans held for sale, represented a $0.8 million inflow for 2012, compared to a net outflow of $1.3 million for 2011 and a $0.5 million inflow for 2010.

Net cash used in investing activities was $88.4 million during 2012, compared with $98.1 million in 2011 and $66.7 million in 2010. During 2012, 2011, and 2010, securities transactions accounted for a net outflow of $53.9 million, $60.4 million, and $99.2 million, respectively. Net origination of loans and principal received from loan pools resulted in $39.2 million in cash outflow for 2012, compared to a $37.0 million outflow for 2011 and a $37.7 million inflow in 2010.

Net cash provided by financing activities was $80.4 million during 2012, compared with $86.5 million in 2011 and $39.2 million in 2010. Sources of cash for 2012 included a $93.1 million increase in net deposits and a net increase in securities sold under agreements to repurchase of $20.5 million, partially offset by a net decrease of $20.0 million in FHLB borrowings, and a net decrease of $8.9 million in federal funds purchased. Increases in deposits of $87.3 million in 2011 and $39.5 million in 2010, and a net increase of $13.0 million in FHLB borrowings in 2011, were main sources of cash inflows in those periods. These increases were partially offset by the $16.0 million cash outflow related to the redemption of preferred stock issued in connection with our participation in the U.S. Treasury’s Capital Purchase Program in 2011, and a net decrease in FHLB borrowings of $13.0 million in 2011, and a $3.0 million decrease in FHLB borrowings in 2010.

To further mitigate liquidity risk, the Bank has several sources of liquidity in place to maximize funding availability and increase the diversification of funding sources. The criteria for evaluating the use of these sources include volume concentration (percentage of liabilities), cost, volatility, and the fit with the current asset/liability management plan. These acceptable sources of liquidity include:

• Fed Funds lines;

• FHLB Advances;

• Brokered deposits;

• Brokered repurchase agreements; and

• Federal Reserve Bank Discount Window.

Fed Funds Lines: Routine liquidity requirements are met by fluctuations in the Bank’s Fed Funds position. The principal function of these funds is to maintain short-term liquidity. Unsecured Fed Funds purchased lines are viewed as a volatile liability and are not used as a long-term funding solution, especially when used to fund long-term assets. Multiple correspondent relationships are preferable and Fed Funds sold exposure to any one customer is continuously monitored. The current Fed Funds purchased limit is 10% of total assets, or the amount of established Fed Funds lines, whichever is smaller. Currently, the Bank has unsecured Fed Fund lines totaling $55.0 million, which lines are tested annually to ensure availability.

FHLB Advances: FHLB advances provide both a source of liquidity and long-term funding for the Bank. Use of this type of funding is coordinated with both the strategic balance sheet growth projections and the interest rate risk profile of the Bank. Factors that are taken into account when contemplating use of FHLB advances are the effective interest rate, the collateral requirements, community investment program credits, and the implications and cost of having to purchase incremental FHLB stock. The current FHLB borrowing limit is 25% of total assets. Currently, the Bank has a $218.0 million advance limit with $120.1 million in outstanding advances as of December 31, 2012, leaving $97.9 million available for liquidity needs as of year-end 2012. These advances are secured by various real estate loans (residential, commercial and agricultural).

Brokered Deposits: The Bank has brokered CD lines/deposit relationships available to help diversify its various funding sources. Brokered deposits offer several benefits relative to other funding sources, such as: maturity structures which cannot be duplicated in the current deposit market, deposit gathering which does not cannibalize the existing deposit base, the unsecured nature of these liabilities, and the ability to quickly generate funds. However, brokered deposits are often viewed as a volatile liability by banking regulators and market participants. This viewpoint, and the desire to not develop a large funding concentration in any one area, is reflected in an internal policy stating that the Bank limit the use of brokered deposits as a funding source to no more than 10% of total assets. Board approval is required to exceed these limits. The Bank will also have to maintain a “well capitalized” standing to access brokered deposits, as an “adequately capitalized” rating would require an FDIC waiver to do so, and an “undercapitalized” rating would prohibit the Bank from using brokered deposits altogether. The Bank had $22.4 million

58

in brokered deposits through the CDARS program, and $20.8 million through the ICS program as of December 31, 2012. Both the CDARS and ICS programs coordinate, on a reciprocal basis, a network of banks to spread deposits exceeding the FDIC insurance coverage limits out to numerous institutions in order to provide insurance coverage for all participating deposits.

Brokered Repurchase Agreements: Brokered repurchase agreements may be established with approved brokerage firms and banks. Repurchase agreements create rollover risk (the risk that a broker will discontinue the relationship due to market factors) and are not used as a long-term funding solution, especially when used to fund long-term assets. Collateral requirements and availability are evaluated and monitored. The current policy limit for brokered repurchase agreements is 10% of total assets. There were no outstanding brokered repurchase agreements at December 31, 2012.

Federal Reserve Bank Discount Window: The FRB Discount Window is another source of liquidity, particularly during difficult economic times. The Bank has a borrowing capacity with the Federal Reserve Bank of Chicago limited by the amount of municipal securities pledged against the line. As of December 31, 2012, the Bank has municipal securities with an approximate market value of $13.2 million pledged, for liquidity purposes.

Interest Rate Risk

The nature of the banking business, which involves paying interest on deposits at varying rates and terms and charging interest on loans at other rates and terms, creates interest rate risk. As a result, net interest margin and earnings and the market value of assets and liabilities are subject to fluctuations arising from the movement of interest rates. We manage several forms of interest rate risk, including asset/liability mismatch, basis risk and prepayment risk. A key management objective is to maintain a risk profile in which variations in net interest income stay within the limits and guidelines of the Bank’s Asset/Liability Management Policy.

Like most financial institutions, the Bank’s net income can be significantly influenced by a variety of external factors, including: overall economic conditions, policies and actions of regulatory authorities, the amounts of and rates at which assets and liabilities reprice, differences in prepayment of loans and securities other than those that are assumed, early withdrawal of deposits, exercise of call options on borrowings or securities, competition, a general rise or decline in interest rates, changes in the slope of the yield-curve, changes in historical relationships between indices (such as LIBOR and prime), and balance sheet growth or contraction. The Asset and Liability Committee (ALCO) seeks to manage interest rate risk under a variety of rate environments via changes in investment and funding strategies and through the structure of deposit and loan product offerings. The risk is monitored and managed within approved policy limits.

The Bank utilizes a third party to perform interest rate risk analysis, which utilizes a modeling program to measure the Bank’s exposure to potential interest rate changes. Measuring and managing interest rate risk is a dynamic process that management performs continually with the objective of maintaining a stable net interest margin. This process relies chiefly on the simulation of net interest income over multiple interest rate scenarios or “shocks.” Management considers net interest income simulation as the best method to evaluate short-term interest rate risk (one-year time frame). The modeled scenarios begin with a base case in which rates are unchanged and include parallel and nonparallel rate shocks. The results of these shocks are measured in two forms: first, the impact on the net interest margin and earnings over one and two year timeframes; and second, the impact on the market value of equity. In addition to measuring the basis risks and prepayment risks noted above, simulations also quantify the earnings impact of rate changes and the cost/benefit of hedging strategies.

59

The following table shows the anticipated effect on net interest income from parallel shocks (up and down) in interest rates over the subsequent twelve month period. As of December 31, 2012, the effect of an immediate and sustained 200 basis point increase in interest rates would be a decline in net interest income of approximately $1.3 million, or 2.3%. Although unlikely in the current low interest rate environment, a 200 basis point decrease in rates would increase net interest income by approximately $1.8 million, or 3.1%. As part of a strategy to mitigate margin compression in a low interest rate environment, management has incorporated interest rate floors on most newly originated floating rate loans. While incorporating interest rate floors on loans has been successful in maintaining the margin in the current low rate environment, the coupon rates on these loans will lag when interest rates rise. These loans have floor rates that are between zero and 2.0% above the fully indexed rate. Therefore, interest rates must rise up to 2.0% before some of these loans would experience an increase in the coupon rate.

The table below shows a positive (asset-sensitive) rate-sensitivity gap of $6.9 million in the one- to three-month repricing category as more assets were subject to repricing during that time period than liabilities. On a cumulative basis, the gap remains asset-sensitive, as our assets subject to repricing exceed our liabilities subject to repricing in every period except three years or more. This static analysis does not capture the effect that rising interest rates are expected to have on loan prepayments. As rates rise, borrowers have little incentive to pay off fixed rate loans prior to maturity. This causes asset classes such as mortgage loans, commercial real estate and portions of the investment portfolio to experience a slow-down in principal pay offs when rates rise. This explains the difference between gap analysis showing asset sensitivity and the net interest income simulation which indicates a decrease in income as rates rise.

In the table above, NOW accounts and savings deposits are allocated across the repricing buckets based on deposit studies of account behavior.

MidWestOne’s funds management policy requires the subsidiary bank to maintain a cumulative rate-sensitivity ratio of 0.75 to 1.25 in the one-year timeframe. As of December 31, 2012, the Bank was within all of its interest rate risk guidelines.

Computations of the prospective effects of hypothetical interest rate changes were based on numerous assumptions. Actual values may differ from those projections set forth above. Further, the computations do not contemplate any actions we could have undertaken in response to changes in interest rates.

MidWestOne Bank (the “Bank”) is also headquartered in Iowa City, Iowa, and provides services to individuals, businesses, governmental units and institutional customers in east central Iowa. The Bank has office locations in Belle Plaine, Burlington, Cedar Falls, Conrad, Coralville, Davenport, Fairfield, Fort Madison, Melbourne, North English, North Liberty, Oskaloosa, Ottumwa, Parkersburg, Pella, Sigourney, Waterloo and West Liberty, Iowa. MidWestOne Insurance Services, Inc. provides personal and business insurance services in Pella, Melbourne and Oskaloosa, Iowa. The Bank is actively engaged in many areas of commercial banking, including: acceptance of demand, savings and time deposits; making commercial, real estate, agricultural and consumer loans, and other banking services tailored for its individual customers. The Wealth Management area of the Bank administers estates, personal trusts, conservatorships, pension and profit-sharing accounts along with providing other management services to customers.

Accounting estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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. The current economic environment has increased the degree of uncertainty inherent in these estimates.

Certain significant estimates: The allowance for loan losses and the fair values of investment securities and other financial instruments involve certain significant estimates made by management. These estimates are reviewed by management routinely and it is reasonably possible that circumstances that exist 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 MidWestOne Financial Group, Inc., a bank holding company, and its wholly-owned subsidiaries which include MidWestOne Bank, a state chartered bank whose primary federal regulator is the Federal Deposit Insurance Corporation, and MidWestOne Insurance Services, Inc. All significant inter-company accounts and transactions have been eliminated in consolidation.

Trust assets, other than cash deposits held by the Bank in a fiduciary or agency capacity for its customers, are not included in the accompanying consolidated financial statements because such accounts are not assets of the Bank.

In the normal course of business, MidWestOne may enter into a transaction with a variable interest entity (“VIE”). VIEs are legal entities whose investors lack the ability to make decisions about the entity’s activities, or whose equity investors do not have the right to receive the residual returns of the entity. The applicable accounting guidance requires MidWestOne to perform ongoing quantitative and qualitative analysis to determine whether it must consolidate the VIE. MidWestOne does not have any ownership interest in or exert any control over the entity, and thus it is not included in the consolidated financial statements. The investment in non-marketable loan participation certificates for which MidWestOne does not have the ability to exert significant influence are accounted for using the cost method.

Presentation of cash flows: For purposes of reporting cash flows, cash and due from banks includes cash on hand, amounts due from banks, and federal funds sold. Cash flows from portfolio loans originated by the Bank, deposits, federal funds purchased, and securities sold under agreements to repurchase are reported net.

Cash receipts and cash payments resulting from acquisitions and sales of loans originated for sale are classified as operating cash flows on a gross basis in the consolidated statements of cash flows.

Investment securities: Certain debt securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Securities not classified as held to maturity, including equity securities with readily determinable fair values, are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company carries its investment securities at fair value, and the Company employs valuation techniques which utilize observable inputs when those inputs are available. These observable inputs reflect assumptions market participants would use in pricing the security, developed based on market data obtained from sources independent of the Company. When such information is not available, the Company employs valuation techniques which utilize unobservable inputs, or those which reflect the Company’s own assumptions about market participants, based on the best information available in the circumstances. These valuation methods typically involve cash flow and other financial modeling techniques. Changes in underlying factors, assumptions, estimates, or other inputs to the valuation techniques could have a material impact on the Company’s future financial condition and results of operations. Fair value measurements are required to be classified as Level 1 (quoted prices), Level 2 (based on observable inputs) or Level 3 (based on unobservable inputs) discussed in more detail in Note 18 to the consolidated financial statements. Available for sale securities are recorded at fair value with unrealized gains and losses excluded from earnings and reported as a separate component of shareholders’ equity until realized.

Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Declines in the fair value of held to maturity and available for sale securities below their cost, that are deemed to be other than temporary, are reflected in earnings as realized losses. In determining whether other than temporary impairment exists, management considers whether: (1) we have the intent to sell the security; (2) it is more likely than not that we will be required to sell the security before recovery of the amortized cost basis; and (3) we do not expect to recover the entire amortized cost basis of the security. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.

Loans: Loans are stated at the principal amount outstanding, net of deferred loan fees and costs and allowance for loan losses. Interest on loans is credited to income as earned based on the principal amount outstanding. Deferred loan fees and costs are amortized using the level yield method over the remaining maturities on the loans.

The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due, unless the credit is well secured and in process of collection. Credit card loans and other personal loans are typically charged off no later than 180 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date, if collection of principal or interest is considered doubtful.

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

Loan Pool Participations: The Company acquired its loan pool participations from the Former MidwestOne during the merger and continued in this business following the merger. However, in 2010, the Company made the decision to exit this line of business and is thus not purchasing new loan pool participations as existing pools pay down. The pools consist of loans to borrowers located throughout the United States.

The Company carries its investment in the loan pools as a separate earning asset on the consolidated balance sheets. Principal or interest restructures, write-downs, or write-offs within the pools are not included in the Company’s disclosures for its loan portfolio, and foreclosed property from loans associated with the pools is not included in other real estate owned on the consolidated balance sheets. The loan pool participations are managed by a non-affiliate servicer operating in Omaha, Nebraska.

Each pool has a different composition and different characteristics. The composition of a loan pool is generally determined by the seller based on its desire to maximize the price it receives for all loans among the various pools. Many of the pools consist of loans primarily secured by single-family, multi-family, and small commercial real estate. Some pools may consist of a large number of small consumer loans that are secured by other assets such as automobiles or mobile homes, while other pools may consist of small to medium balance commercial loans. Some may contain a mixture of such loans and other types of loans.

The Company invested in pools consisting of both performing loans and past-due nonperforming loans. The price bid and paid for such a loan pool was determined based on the composition of the particular pool, the amounts the servicer believed could be collected on such a pool, and the risks associated with the collection of such amounts.

Upon the acquisition of a participation interest in a loan pool, the Company assumed the risk of loss on a pro-rata basis. The extent of such risk is dependent on a number of factors, including the servicer’s ability to locate the debtors, the debtors’ financial

69

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

condition, the possibility that a debtor may file for protection under applicable bankruptcy laws, the servicer’s ability to locate the collateral, if any, for the loan and to obtain possession of such collateral, the value of such collateral, and the length of time it takes to realize the ultimate recovery either through collection procedures or through a resale of the loans following a restructure.

A cost “basis” was assigned to each individual loan acquired on a cents per dollar (discounted price) based on the servicer’s assessment of the recovery potential of each such loan. This methodology assigns a higher basis to performing loans with greater potential collectability and a lower basis to those loans identified as having little or no potential for collection.

Loan pool participations are shown on the Company’s consolidated balance sheets as a separate asset category. The original carrying value of loan pool participations represents the discounted price paid by the Company to acquire its participation interests in various loan pools purchased by the servicer. The Company’s investment balance is reduced as the servicer collects principal payments on the loans and remits the proportionate share of such payments to the Company.

The loan pool participations acquired are accounted for in accordance with the provisions of ASC Topic 310.

ASC Topic 310 provides guidance on the accounting for purchased loans that show evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the purchaser will be unable to collect all contractually required payments receivable. ASC Topic 310 generally requires that the excess of the estimated cash flows expected to be collected on the loan over the initial investment be accreted over the estimated remaining life of loan.

According to the ASC Topic 310, in order to apply the interest method of recognition to these types of loans, there must be sufficient information to reasonably estimate the amount and timing of the cash flows expected to be collected. When that is not the case, the loan should be accounted for as a nonaccrual status applying the cash basis income recognition to the loan.

The Company has developed and implemented procedures to determine if accretion of the discount (“accretable yield”) on the purchased loans in a pool is required under ASC Topic 310. Given the impaired nature of the loan pools typically purchased, the individual loans were evaluated for ASC Topic 310 purposes by the end of a six-month window from the date of purchase. This provided time to assess the quality of the loans and assign basis to each loan within the pool. Purchased loans were evaluated individually with a determination made utilizing various criteria including: past-due status, late payments, legal status of the loan (not in foreclosure, judgment against the borrower, or referred to legal counsel), frequency of payments made, collateral adequacy and the borrower’s financial condition. If all the criteria were met, the Company utilizes the accounting treatment for that individual loan required by ASC Topic 310 with the accretable yield difference between the expected cash flows and the purchased basis accreted into income on the level yield basis over the anticipated life of the loan. If any of the six criteria are not met, the loan is accounted for on the cash-basis of accounting.

In the event that a prepayment is received on a loan accounted for under ASC Topic 310, the accretable yield is recomputed and the revised amount accreted over the estimated remaining life of the loan on the level yield basis. If a loan subject to accretable yield under ASC Topic 310 fails to make timely payments, it is subject to classification and an allowance for loss would be established.

Collection expenses incurred by the servicer are netted against discount income. Discount income is added to interest income and reflected as one amount on the Company’s consolidated statements of operations.

Interest income is only recognized when collected and actually remitted to the Company by the servicer for those loans subject to nonaccrual status in accordance with ASC Topic 310. Many of the pools that have been purchased by the servicer do not include purchased interest in the cost basis; thus, interest collected does not have a cost basis and represents profit. Interest income collected by the servicer is reflected in the Company’s consolidated financial statements as interest income and is included as part of interest and discount on loan pool participations.

Loans held for sale: Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value, as determined by aggregate outstanding commitments from investors or current investor yield requirements. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income.

Mortgage loans held for sale are generally sold with the mortgage servicing rights retained. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price plus the value of servicing rights, less the carrying value of the related mortgage loans sold.

Allowance for loan losses: The allowance for loan losses is established as losses estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a quarterly basis by management and is based upon management’s periodic review of the collectiblity of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available.

The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as doubtful, substandard or special mention. For such loans that are also classified as impaired as well as loans meeting the definition of a troubled debt restructuring, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan are lower than the carrying value of that loan. The general component covers loans not classified as impaired and is based on historical loss experience adjusted for qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects that margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.

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

Large groups of smaller-balance, homogeneous loans are collectively evaluated for impairment. Accordingly, the Bank generally does not separately identify individual consumer and residential loans for impairment unless they meet the definition of a troubled debt restructure.

Transfers of financial assets: Revenue from the origination and sale of loans in the secondary market is recognized upon the transfer of financial assets and 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 Bank and its affiliates; (2) the transferee has the right to pledge or exchange the assets it received and no condition both constrains the transferee from taking advantage of its right to pledge or exchange and provides more than a trivial benefit to the transferor; and (3) the Bank and its affiliates do 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.

Revenue recognition: Trust fees, deposit account service charges and other fees are recognized when payment is received for the services (cash basis), which generally occurs at the time the services are provided.

Credit-related financial instruments: In the ordinary course of business, the Bank 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. The Bank records a liability to the extent losses on its commitments to lend are probable.

Premises and equipment: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. The estimated useful lives and primary method of depreciation for the principal items are as follows:

	Years
Type of Assets	Minimum		Maximum	Depreciation Method
Buildings and leasehold improvements	10	-	30	Straight-line
Furniture and equipment	3	-	10	Straight-line

Charges for maintenance and repairs are expensed as incurred. When assets are retired or disposed of the related cost and accumulated depreciation are removed from the respective accounts and the resulting gain or loss is recorded.

Other real estate owned: Other real estate owned acquired in satisfaction of loans is recorded at the lower of cost or fair value less estimated costs of disposal. When a property is acquired, the excess of the recorded investment in the property over its estimated fair value, less estimated costs of disposal, if any, is charged to the allowance for loan losses.

Subsequent declines in the estimated fair value are recorded in a valuation allowance account. Additions to or reductions from valuation allowances, along with net operating results of the property, are included in other operating expenses.

Mortgage servicing rights: Mortgage servicing rights are recorded at fair value based on assumptions through a third-party valuation service. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the servicing cost per loan, the discount rate, the escrow float rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses.

Bank-owned life insurance: Bank-owned life insurance is carried at cash surrender value, net of surrender and other charges, with increases/decreases reflected as income/expense in the consolidated statements of operations.

Employee benefit plans: Deferred benefits under a salary continuation plan are charged to expense during the period in which the participating employees attain full eligibility.

Stock-based compensation: Compensation expense for share based awards is recorded over the vesting period at the fair value of the award at the time of grant. The exercise price of options or fair value of nonvested shares granted under the Company’s incentive plans is equal to the fair market value of the underlying stock at the grant date. The Company assumes no projected forfeitures on its stock based compensation, since actual historical forfeiture rates on its stock based incentive awards has been negligible.

Income taxes: The Company files a consolidated federal income tax return. Income tax expense is generally allocated as if the Company and its subsidiaries file separate income tax returns. For state purposes, the Bank files a franchise tax return and the remaining entities file a consolidated income tax return. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

There were no material unrecognized tax benefits or any interest or penalties on any unrecognized tax benefits as of December 31, 2012 and 2011.

Any interest and penalties related to income taxes would be recorded as other operating expense in the consolidated statements of operations.

Preferred Stock: On February 6, 2009, the Company issued 16,000 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A (”Preferred Stock”), together with a ten-year warrant to acquire 198,675 shares of common stock, to the U.S. Department of the Treasury (the “Treasury”) under the Capital Purchase Program (the “CPP”) for an aggregate purchase price of $16.0 million. Upon issuance, the fair values of the senior preferred stock and the common stock warrants were computed as if the securities were issued on a stand-alone basis.

MIDWESTONE FINANCIAL GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

On July 6, 2011, the Company announced that it had repurchased the 16,000 shares of Preferred Stock issued to the Treasury under the CPP for an aggregate repurchase price of $16.1 million including accrued interest.

On July 27, 2011, the Company announced that it had repurchased the common stock warrant issued to the Treasury as part of the CPP for $1.0 million. The warrant had allowed Treasury to purchase 198,675 shares of MidWestOne common stock at $12.08 per share.

Common Stock: On July 26, 2011, our Board of Directors authorized the implementation of a share repurchase program to repurchase up to $1.0 million of the Company’s outstanding shares of common stock through December 31, 2011. Pursuant to the program, we repurchased 45,039 shares of common stock during the third quarter of 2011 for an aggregate cost of $658,000. On October 18, 2011, our Board of Directors amended the Company’s share repurchase program by increasing the remaining amount of authorized repurchases to $5.0 million, and extending the expiration of the program to December 31, 2012. For the year of 2012 we repurchased a total of 104,518 shares of common stock at a cost of $1.8 million, with $2.4 million remaining in the current share repurchase program at December 31, 2012 .

On January 15, 2013, the Company's board of directors announced the renewal of the Company's share repurchase program, extending the expiration of the program to December 31, 2014 and increasing the remaining amount of authorized repurchases under the program to $5.0 million from the approximately $2.4 million of authorized repurchases that had previously remained. Pursuant to the program, the Company may continue to repurchase shares from time to time in the open market, and the method, timing and amounts of repurchase will be solely in the discretion of the Company's management. The repurchase program does not require the Company to acquire a specific number of shares. Therefore, the amount of shares repurchased pursuant to the program will depend on several factors, including market conditions, capital and liquidity requirements, and alternative uses for cash available.

Comprehensive income: Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of shareholders’ equity on the consolidated balance sheets, and are disclosed in the consolidated statements of comprehensive income.

The components of accumulated other comprehensive income, included in shareholders’ equity, net of tax, are as follows:

There were no held to maturity securities with gross unrealized losses as of December 31, 2011.

The Company’s assessment of other-than-temporary impairment is based on its reasonable judgment of the specific facts and circumstances impacting each individual security at the time such assessments are made. The Company reviews and considers factual information, including expected cash flows, the structure of the security, the credit quality of the underlying assets and the current and anticipated market conditions.

The receipt of principal, at par, and interest on mortgage-backed securities is guaranteed by the respective government-sponsored agency guarantor, such that the Company believes that its mortgage-backed securities do not expose the Company to credit-related losses. The Company's mortgage-backed securities portfolio consisted of securities predominantly underwritten to the standards of and guaranteed by the government-sponsored agencies of FHLMC, FNMA and GNMA.

At December 31, 2012, approximately 63% of the municipal obligations held by the Company were Iowa-based. The Company does not intend to sell these municipal obligations, and it is more likely than not that the Company will not be required to sell them until the recovery of its cost. Due to the issuers’ continued satisfaction of their obligations under the securities in accordance with their contractual terms and the expectation that they will continue to do so, management’s intent and ability to hold these securities for a period of time sufficient to allow for any anticipated recovery in fair value, as well as the evaluation of the

fundamentals of the issuers’ financial condition and other objective evidence, the Company believes that the municipal obligations identified in the tables above were temporarily depressed as of December 31, 2012 and 2011.

At December 31, 2012, the Company owned six collateralized debt obligations backed by pools of trust preferred securities with an original cost basis of $9.8 million. The book value of these securities as of this date totaled $1.8 million after other-than-temporary impairment charges during 2008, 2009, and 2010. All of the Company’s trust preferred collateralized debt obligations are in mezzanine tranches and are currently rated less than investment grade by Moody’s Investor Services. They are secured by trust preferred securities of banks and insurance companies throughout the United States, and were rated as investment grade securities when purchased between March 2006 and December 2007. However, as the banking climate eroded during 2008, the securities experienced cash flow problems. Due to continued market deterioration in these securities during 2009 and 2010, additional pre-tax charges to earnings were recorded. No additional charges have been recognized during 2011 or 2012. The market for these securities is considered to be inactive. The Company uses a discounted cash flow model to determine the estimated fair value of its pooled trust preferred collateralized debt obligations and to assess other-than-temporary impairment. The assumptions used in preparing the discounted cash flow model include the following: estimated discount rates (using yields of comparable traded instruments adjusted for illiquidity and other risk factors), estimated deferral and default rates on collateral, and estimated cash flows. The Company also reviewed a stress test of these securities to determine the additional deferrals or defaults in the collateral pool in excess of what the Company believes is probable, before the payments on the individual securities are negatively impacted.

As of December 31, 2012, the Company also owned $1.7 million of equity securities in banks and financial service-related companies. Equity securities are considered to have other-than-temporary impairment whenever they have been in a loss position, compared to current book value, for twelve consecutive months, and the Company does not expect them to recover to their original cost basis. During 2012, no impairment charges were recorded, as the affected equity securities were not deemed impaired due to stabilized market prices in relation to the Company’s original purchase price.

The following table provides a roll forward of credit losses on fixed maturity securities recognized in net income:

Additional credit losses:

It is reasonably possible that the fair values of the Company’s investment securities could decline in the future if the overall economy and the financial condition of some of the issuers deteriorate and the liquidity of these securities remains depressed. As a result, there is a risk that additional other-than-temporary impairments may occur in the future and any such amounts could be material to the Company’s consolidated statements of operations.

The contractual maturity distribution of investment debt securities at December 31, 2012, is summarized as follows:

Mortgage-backed and collateralized mortgage obligations are collateralized by mortgage loans guaranteed by U.S. government agencies. Experience has indicated that principal payments will be collected sooner than scheduled because of prepayments. Therefore, these securities are not scheduled in the maturity categories indicated above. Other equity securities available for sale with an amortized cost of $1.6 million and a fair value of $1.7 million are also excluded from this table.

Proceeds from the sales of investment securities available for sale during 2012 were $18.3 million. During 2011 there were no sales of investment securities available for sale, as realized gains during 2011 were the result of the accelerated maturity of certain debt securities possessing a call feature, while in 2010 sale proceeds were $16.9 million.

Other investment securities include investments in Federal Home Loan Bank (“FHLB”) stock. The carrying value of the FHLB stock at December 31, 2012 and December 31, 2011 was $11.1 million and $12.2 million, respectively, which is included in the Other Assets line of the consolidated balance sheets. This security is not readily marketable and ownership of FHLB stock is a requirement for membership in the FHLB Des Moines. The amount of FHLB stock the Bank is required to hold is directly related to the amount of FHLB advances borrowed. Because there are no available market values for this security, it is carried at cost and evaluated for potential impairment each quarter. Redemption of this investment is at the option of the FHLB.

Realized gains and losses on sales are determined on the basis of specific identification of investments based on the trade date. Realized gains (losses) on investments, including impairment losses for the years ended December 31, 2012, 2011 and 2010, were as follows:

Loan Portfolio Segment Risk Characteristics

Agricultural - Agricultural loans, most of which are secured by crops, livestock, and machinery, are provided to finance capital improvements and farm operations as well as acquisitions of livestock and machinery. The ability of the borrower to repay may be affected by many factors outside of the borrower’s control including adverse weather conditions, loss of livestock due to disease or other factors, declines in market prices for agricultural products and the impact of government regulations. The ultimate repayment of agricultural loans is dependent upon the profitable operation or management of the agricultural entity. Collateral for these loans generally includes accounts receivable, inventory, equipment and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business.

Commercial and Industrial - Commercial and industrial loans are primarily made based on the reported cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The collateral support provided by the borrower for most of these loans and the probability of repayment is based on the liquidation of the pledged collateral and enforcement of a personal guarantee, if any exists. The primary repayment risks of commercial and financial loans are that the cash flows of the borrower may be unpredictable, and the collateral securing these loans may fluctuate in value. The size of the loans the Company can offer to commercial customers is less than the size of the loans that competitors with larger lending limits can offer. This may limit the Company’s ability to establish relationships with the area’s largest businesses. As a result, the Company may assume greater lending risks than financial institutions that have a lesser concentration of such loans and tend to make loans to larger businesses. Collateral for these loans generally includes accounts receivable, inventory, equipment and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business. In addition, if the United States economy does not meaningfully improve, this could harm or continue to harm, as the case may be, the businesses of our commercial and industrial customers and reduce the value of the collateral securing these loans.

Commercial Real Estate - The Company offers mortgage loans to commercial and agricultural customers for the acquisition of real estate used in their business, such as offices, warehouses and production facilities, and to real estate investors for the acquisition of apartment buildings, retail centers, office buildings and other commercial buildings. The market value of real estate securing commercial real estate loans can fluctuate significantly in a short period of time as a result of market conditions in the geographic area in which the real estate is located. Adverse developments affecting real estate values in one or more of the Company’s markets could increase the credit risk associated with its loan portfolio. Additionally, real estate lending typically involves higher loan principal amounts and the repayment of the loans generally is dependent, in large part, on sufficient income from the properties

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

securing the loans to cover operating expenses and debt service. Economic events or governmental regulations outside of the control of the borrower or lender could negatively impact the future cash flow and market values of the affected properties.

Residential Real Estate - The Company generally retains short-term residential mortgage loans that are originated for its own portfolio but sells most long-term loans to other parties while retaining servicing rights on the majority of such loans. The market value of real estate securing residential real estate loans can fluctuate as a result of market conditions in the geographic area in which the real estate is located. Adverse developments affecting real estate values in one or more of the Company’s markets could increase the credit risk associated with its loan portfolio. Additionally, real estate lending typically involves higher loan principal amounts and the repayment of the loans generally is dependent, in large part, on the borrower’s continuing financial stability, and are therefore more likely to be affected by adverse personal circumstances.

Consumer - Consumer loans typically have shorter terms, lower balances, higher yields and higher risks of default.  Consumer loan collections are dependent on the borrower’s continuing financial stability, and are therefore more likely to be affected by adverse personal circumstances. Collateral for these loans generally includes automobiles, boats, recreational vehicles, mobile homes, and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to recover and may fluctuate in value based on condition. In addition, a decline in the United States economy could result in reduced employment, impacting the ability of customers to repay their obligations.

Loans acquired with deteriorated credit quality (loan pool participations) - The underlying loans in the loan pool participations include both fixed-rate and variable-rate instruments. No amounts for interest due are reflected in the carrying value of the loan pool participations. Based on historical experience, the average period of collectibility for loans underlying loan pool participations, many of which have exceeded contractual maturity dates, is approximately three to five years. Loan pool balances are affected by the payment and refinancing activities of the borrowers resulting in pay-offs of the underlying loans and reduction in the balances. Collections from the individual borrowers are managed by the loan pool servicer and are affected by the borrower’s financial ability and willingness to pay, foreclosure and legal action, collateral value, and the economy in general.

Charge-off Policy

The Company requires a loan to be charged-off as soon as it becomes apparent that some loss will be incurred, or when its collectability is sufficiently questionable that it no longer is considered a bankable asset. The primary considerations when determining if and how much of a loan should be charged-off are as follows: (1) the potential for future cash flows; (2) the value of any collateral; and (3) the strength of any co-makers or guarantors.

When it is determined that a loan requires partial or full charge-off, a request for approval of a charge-off is submitted to the Bank’s President, Executive Vice President of Lending, and the Senior Regional Loan officer. The Bank’s Board of Directors formally approves all loan charge-offs at the next regularly scheduled meeting. Once a loan is charged-off, it cannot be restructured and returned to the Bank’s books.

The Allowance for Loan and Lease Losses - Bank Loans

The Company requires the maintenance of an adequate allowance for loan and lease losses (“ALLL”) in order to cover probable losses without eroding the Company’s capital base. Calculations are done at each quarter end, or more frequently if warranted, to analyze the collectability of loans and to ensure the adequacy of the allowance. In line with FDIC directives, the ALLL calculation does not include consideration of loans held for sale or off-balance-sheet credit exposures (such as unfunded letters of credit). Determining the appropriate level for the ALLL relies on the informed judgment of management, and as such, is subject to inaccuracy. Given the inherently imprecise nature of calculating the necessary ALLL, the Company’s policy permits an “unallocated” allowance between 15% above and 5% below the “indicated reserve.” These unallocated amounts are present due to the inherent imprecision in the ALLL calculation.

Loans Reviewed Individually for Impairment

The Company identifies loans to be reviewed and evaluated individually for impairment, based on current information and events, and the probability that the borrower will be unable to repay all amounts due according to the contractual terms of the loan agreement. Specific areas of consideration include: size of credit exposure, risk rating, delinquency, nonaccrual status, and loan classification.

The level of individual impairment is measured using one of the following methods: (1) the fair value of the collateral less costs to sell; (2) the present value of expected future cash flows, discounted at the loan’s effective interest rate; or (3) the loan’s observable

80

MIDWESTONE FINANCIAL GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

market price. Loans that are deemed fully collateralized or have been charged down to a level corresponding with any three of the measurements require no assignment of reserves from the ALLL.

All loans deemed troubled debt restructure or “TDR” are considered impaired. A loan is considered a TDR when the Bank, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that the Bank would not otherwise consider. All of the following factors are indicators that the Bank has granted a concession (one or multiple items may be present):

• The borrower receives a reduction of the stated interest rate for the remaining original life of the debt.

• The borrower receives an extension of the maturity date or dates at a stated interest rate lower that the current market interest rate for new debt with similar risk characteristics.

• The borrower receives a reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement.

• The borrower receives a deferral of required payments (principal and/or interest).

• The borrower receives a reduction of the accrued interest.

The following table sets forth information on the Company’s troubled debt restructurings by class of financing receivable occurring during the stated periods:

During the year ended December 31, 2012 four loans were classified as new troubled debt restructures (TDR). One commercial and industrial loan was added to the TDR loan classification due to being extended and re-amortized to a longer period. This credit also experienced a payment default during 2012. Two farmland loans, both to the same borrower, were classified as new TDRs during 2012 due to a court ordered interest rate reduction in connection with a Chapter 12 bankruptcy. One one- to four- family junior lien was granted a rate concession and advanced additional funds for taxes and insurance due to borrower financial difficulties during 2012.

During the year ended December 31, 2011, one commercial and industrial loan was added to the TDR loan classification due to a partial charge-off of its outstanding principal and an adjustment to its terms granting a below market interest rate. Likewise, one construction and development loan was also added due to a partial balance charge-off and interest rate concession. Four commercial real estate loans, all to the same borrower, were classified as new TDRs during 2011 due to the extension of a forbearance agreement

81

and the granting of a below market interest rate. These four credits also experienced a payment default during 2011. One commercial real estate loan that was a new TDR during 2011 due to a below market interest rate was on non-accrual at year-end. One- to four- family first lien restructures increased by one loan due to an interest rate concession. A commercial real estate loan TDR that was on non-accrual at December 31, 2010, was rewritten with a rate concession and had additional funds advanced in 2011, and was reported as a new TDR in 2011.

During the year ended December 31, 2010, two agricultural loans had been added to the restructured classification due to the modification of loan guarantees, a charge-off of $500,000, and both notes being at below market interest rates with interest-only payments being required. One farmland loan related to the agricultural credits was also classified as a TDR due to having the interest rate modified to a below market rate. One commercial real estate loan became a TDR due to an interest rate concession. One residential real estate first lien was identified as a TDR in 2010, having been granted a below market interest rate with normally required private mortgage insurance being waived. It was considered a workout situation by management. Finally, one home equity loan was designated a TDR due to a partial charge-off of the principal balance.

Loans by class of financing receivable modified as TDRs within the previous 12 months and for which there was a payment default during the stated periods were:

Loans Reviewed Collectively for Impairment

All loans not evaluated individually for impairment are grouped together by type (i.e. commercial, agricultural, consumer, etc.) and further segmented within each subset by risk classification (i.e. pass, special mention, and substandard). Homogeneous loans past due 60-89 days and 90+ days, are classified special mention and substandard, respectively, for allocation purposes.

The Company’s historical loss experience for each loan type is calculated using the fiscal quarter-end data for the most recent 20 quarters as a starting point for estimating losses. In addition, other prevailing qualitative or environmental factors likely to cause probable losses to vary from historical data are incorporated in the form of adjustments to increase or decrease the loss rate applied to each group. These adjustments are documented, and fully explain how the current information, events, circumstances, and conditions impact the historical loss measurement assumptions.

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

• Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses.

• Changes in international, national, regional, and local economic and business conditions and developments that affect

82

MIDWESTONE FINANCIAL GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

the collectability of the portfolio, including the condition of various market segments.

• Changes in the nature and volume of the portfolio and in the terms of loans.

• Changes in the experience, ability and depth of lending management and other relevant staff.

• Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans.

• Changes in the quality of our loan review system.

• Changes in the value of underlying collateral for collateral-dependent loans.

• The existence and effect of any concentrations of credit, and changes in the level of such concentrations.

• The effect of other external factors, such as competition and legal and regulatory requirements, on the level of estimated credit losses in the Bank’s existing portfolio.

The items listed above are used to determine the pass percentage for loans evaluated collectively and, as such, are applied to the loans risk rated pass. Due to the inherent risks associated with special mention risk rated loans (i.e., early stages of financial deterioration, technical exceptions, etc.), this subset is reserved at two times the pass allocation factor to reflect this increased risk exposure. In addition, non-impaired loans classified as substandard loans carry exponentially greater risk than special mention loans, and as such, this subset is reserved at six times the pass allocation. Further, non-impaired loans identified as substandard “performing collateral deficient” are reserved at 12 times the pass allocation due to the perceived additional risk for such credits.

The Allowance for Loan and Lease Losses - Loan Pool Participations

The Company requires that the loan pool participation ALLL will be at least sufficient to cover the next quarter’s estimated charge-offs as presented by the servicer. Currently, charge-offs are netted against the income the Company receives, thus the balance in the loan pool reserve is not affected and remains stable. In essence, a provision for loan losses is made that is equal to the quarterly charge-offs, which is deducted from income received from the loan pools. By maintaining a sufficient reserve to cover the next quarter’s charge-offs, the Company will have sufficient reserves in place should no income be collected from the loan pools during the quarter. In the event the estimated charge-offs provided by the servicer are greater than the loan pool ALLL, an additional provision is made to cover the difference between the current ALLL and the estimated charge-offs provided by the servicer.

Loans Reviewed Individually for Impairment

The loan servicer reviews the portfolio quarterly on a loan-by-loan basis, and loans that are deemed to be impaired are charged-down to their estimated value during the next calendar quarter. All loans that are to be charged-down are reserved against in the ALLL adequacy calculation. Loans that continue to have an investment basis that have been charged-down are monitored, and if additional impairment is noted the reserve requirement is increased on the individual loan.

Loans Reviewed Collectively for Impairment

The Company utilizes the annualized average of portfolio loan (not loan pool) historical loss per risk category over a two year period of time. Supporting documentation for the technique used to develop the historical loss rate for each group of loans is required to be maintained. It is management’s assessment that the two year rate is most reflective of the estimated credit losses in the current loan pool portfolio.

Special Mention - A special mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.

Substandard - Substandard loans are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected.

84

MIDWESTONE FINANCIAL GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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

Loss - Loans classified loss are generally considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be effected in the future.

Non-accrual and Delinquent Loans

Loans are placed on non-accrual when (1) payment in full of principal and interest is no longer expected or (2) principal or interest has been in default for 90 days or more (unless the loan is both well secured with marketable collateral and in the process of collection). All loans rated doubtful or worse are placed on non-accrual.

A non-accrual asset may be restored to an accrual status when (1) all past due principal and interest has been paid (excluding renewals and modifications that involve the capitalizing of interest) or (2) the loan becomes well secured and is in the process of collection. An established track record of performance is also considered when determining accrual status.

Delinquency status of a loan is determined by the number of days that have elapsed past the loan’s payment due date, using the following classification groupings: 30-59 days, 60-89 days and 90 days or more.

Loan Pool Participations

ASC Topic 310 addresses accounting for differences between contractual cash flows and cash flows expected to be collected from an investor’s initial investment in loans or debt securities acquired in a transfer if those differences are attributable, at least in part, to credit quality. The loans underlying the loan pool participations were evaluated individually when purchased for application of ASC Topic 310, utilizing various criteria including: past-due status, late payments, legal status of the loan (not in foreclosure, judgment against the borrower, or referred to legal counsel), frequency of payments made, collateral adequacy and the borrower’s financial condition. If all the criteria were met, the individual loan utilized the accounting treatment required by ASC Topic 310 with the accretable yield difference between the expected cash flows and the purchased basis accreted into income on the level yield basis over the anticipated life of the loan. If any of the six criteria were not met at the time of purchase, the loan was accounted for on the cash basis of accounting.

The loan servicer reviews the portfolio quarterly on a loan-by-loan basis, and loans that are deemed to be impaired are charged-down to their estimated value. As of December 31, 2012, approximately 65% of the loans were contractually current or less than 90 days past due, while 35% were contractually past due 90 days or more. Many of the loans were acquired in a contractually past due status, which is reflected in the discounted purchase price of the loans. Performance status is monitored on a monthly basis. The 35% contractually past due includes loans in litigation and foreclosed property.

Note 5. Intangible Assets

Intangible assets decreased to $9.5 million as of December 31, 2012, from $10.2 million as of December 31, 2011, as a result of normal amortization. Amortization of intangible assets is recorded using an accelerated method based on the estimated useful life of the core deposit intangible, customer list intangible and insurance agency intangible. Projections of amortization expense are based on existing asset balances and the remaining useful lives.

The trade name intangible is not amortized but is evaluated for impairment annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. No impairment was recorded on this asset in 2012, 2011, or 2010.

The following table summarizes the amounts and carrying values of intangible assets as of December 31, 2012 and 2011:

	$	20,382	$	21,662

The Bank is a member of The Federal Home Loan Bank of Des Moines, and ownership of FHLB stock is a requirement for membership in the FHLB Des Moines. The amount of FHLB stock the Bank is required to hold is directly related to the amount of FHLB advances borrowed. Because this security is not readily marketable and there are no available market values, this security is carried at cost and evaluated for potential impairment each quarter. Redemption of this investment is at the option of the FHLB.

Mortgage servicing rights are recorded at fair value based on a third-party valuation service. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the servicing cost per loan, the discount rate, the escrow float rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses.

Note 7. Loans Serviced for Others

Loans serviced for others are not included in the accompanying consolidated balance sheets. The unpaid principal balances of mortgage and other loans serviced for others were $358.4 million and $317.4 million at December 31, 2012 and 2011, respectively. Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts, disbursing payments to investors and collection and foreclosure processing. Loan servicing income is recorded on the accrual basis and includes servicing fees from investors and certain charges collected from borrowers, such as late payment fees, and is net of fair value adjustments to capitalized mortgage servicing rights.

Note 8. Time Deposits

At December 31, 2012, the scheduled maturities of certificates of deposits were as follows:

The Company had $22.4 million in brokered time deposits through the CDARS program as of December 31, 2012. The CDARS program coordinates, on a reciprocal basis, a network of banks to spread deposits exceeding the FDIC insurance coverage limits out to numerous institutions in order to provide insurance coverage for all participating deposits.

Note 9. Short-Term Borrowings

At December 31, 2012 and 2011, the Company had no borrowings through the Federal Reserve Discount Window, while the borrowing capacity was $11.9 million and $11.5 million, respectively. As of December 31, 2012, the Bank had $13.2 million of municipal securities pledged to the Federal Reserve to secure potential borrowings. The Company also has various other unsecured Federal Funds agreements with correspondent banks. As of December 31, 2012 and 2011 there were zero and $8.9 million of borrowings through these correspondent bank federal funds agreements, respectively.

Securities sold under repurchase agreements with balances of $68.8 million and $48.3 million as of December 31, 2012 and 2011, respectively, are used by the Company to acquire funds from customers where the customer is required or desires to have their funds supported by collateral consisting of U.S. Treasury securities, U.S. Government agencies or other types of securities. The repurchase agreement is a promise to sell these securities to a customer at a certain price and repurchase them within one to four days after the transaction date at that same price plus interest accrued at an agreed upon rate. The weighted average interest rate on these agreements was 0.30% and 0.45% at December 31, 2012 and 2011, respectively.

Note 10. Federal Home Loan Bank Borrowings and Long-Term Debt

As a member of The Federal Home Loan Bank of Des Moines, the Bank may borrow funds from the FHLB in amounts up to 35% of the Bank’s total assets, provided the Bank is able to pledge an adequate amount of qualified assets to secure the borrowings. Advances from the FHLB are collateralized primarily by 1-4 unit residential, commercial and agricultural real estate first mortgages equal to various percentages of the total outstanding notes. As of December 31, 2012, the Bank had $367.3 million of collateral pledged to the FHLB. As of December 31, 2012 and 2011, Federal Home Loan Bank borrowings were as follows:

In connection with the Company’s merger with the Former MidWestOne in March 2008, the Company acquired $15.6 million in long-term subordinated debt from the Former MidwestOne’s issuance of a pooled trust preferred security. The junior subordinated debentures supporting the trust preferred securities have a maturity date of December 15, 2042, do not require any principal amortization and were callable on December 15, 2012 at par at the Company’s option. The interest rate was fixed on $7.8 million of the debt until December 15, 2012, at an interest rate of 6.48%, after which the rate became variable, as is the case with the remaining balance of the debt. The variable rate is based on the three month LIBOR rate plus 1.59% with interest payable quarterly. At December 31, 2012, the interest rate was at 1.90%. During the year the interest rate ranged from 4.31% to 1.90%. Interest expense recorded during 2012 and 2011 was $0.7 million and $0.7 million, respectively.

The Company has recorded a deferred tax asset for the future tax benefits of Iowa net operating loss carry forwards and certain impairment losses on investment securities. The Iowa net operating loss carry forwards amounting to approximately $34.6 million will expire in various amounts from 2018 to 2032. As of December 31, 2012 and 2011, the Company believed it was more likely than not that all temporary differences associated with the Iowa corporate tax return, as well as certain impairment and capital losses on securities at the federal and state level, would not be fully realized. Accordingly, the Company has recorded a valuation allowance to reduce the net operating loss carry forwards and certain impairment losses on securities. A valuation allowance related to the remaining deferred tax assets has not been provided because management believes it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets.

The Company had no material unrecognized tax benefits as of December 31, 2012 and 2011.

Note 12. Employee Benefit Plans

Prior to the Company’s merger with the Former MidWestOne, the Bank sponsored a noncontributory defined benefit pension plan for substantially all its employees. Effective December 31, 2007, the Bank elected to curtail the plan by limiting this employee benefit to those employees vested as of December 31, 2007. During the second quarter of 2012, the Company completed the liquidation of plan assets and full termination of the plan, including full benefit payout to plan participants. The total amount of the Company’s required contribution to fully fund the plan for liquidation was $6.1 million, pre-tax, which is included in Salaries and Employee Benefits expense on the consolidated statements of operations.

The Company has a salary reduction profit-sharing 401(k) plan covering all employees fulfilling minimum age and service requirements. Employee contributions to the plan are optional. Employer contributions are discretionary and may be made to the plan in an amount equal to a percentage of each participating employee’s salary. The 401(k) contribution expense for this plan totaled $667,000, $629,000 and $614,000 for the years ended December 31, 2012, 2011 and 2010, respectively.

The Company has an employee stock ownership plan (ESOP) covering all employees fulfilling minimum age and service requirements. Employer contributions are discretionary and may be made to the plan in an amount equal to a percentage of each participating employee’s salary. The ESOP contribution expense for this plan totaled $635,000, $534,000 and $266,000 for the years ended December 31, 2012, 2011 and 2010, respectively.

The Company has a salary continuation plan for several officers and directors. These plans provide annual payments of various amounts upon retirement or death. The Company accrues the expense for these benefits by charges to operating expense during the period the respective officer or director attains full eligibility. The amount charged to operating expense during the years ended December 31, 2012, 2011 and 2010 totaled $359,000, $372,000 and $320,000, respectively. To provide the retirement benefits, the Company carries life insurance policies with cash values totaling $13.5 million, $13.0 million and $12.6 million at December 31, 2012, 2011 and 2010, respectively.

Note 13. Stock Compensation Plans

The Company maintains the MidWestOne Financial Group, Inc. 2008 Equity Incentive Plan (the “Plan”) as a means to attract, retain and reward certain designated employees and directors of, and service providers to, the Company and its subsidiaries. Under the terms of the Plan, the Company may grant a total of 750,000 total shares of the Company’s common stock as stock options, stock appreciation rights or stock awards (including restricted stock units) and may also grant cash incentive awards to eligible individuals. As of December 31, 2012 and 2011, 496,614 and 494,389 shares, respectively, of the Company’s common stock remained available for future awards under the Plan.

During 2012, the Company recognized $266,000 of stock based compensation expense, which consisted of $234,000 of expense related to restricted stock unit grants and $32,000 of expense related to stock option grants. In comparison, during 2011, the Company recognized $220,000 of stock based compensation expense, which consisted of $171,000 for restricted stock unit grants and $49,000 for stock option grants, while total stock based compensation expense in 2010 was $190,000 which consisted of $140,000 for restricted stock unit grants and $50,000 for stock option grants.

Incentive Stock Options:

The Company is required to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as compensation expense in the Company’s consolidated statements of operations over the requisite service periods using a straight-line method. Since stock-based compensation expense is based on awards ultimately expected to vest, the expense is reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

The stock options have a maximum term of ten years, an exercise price equal to the fair market value of a share of stock on the date of grant and vest 25% per year over four years, with the first vesting date being the one-year anniversary of the grant date.

During 2012, the Company received $590,000 of cash from the exercise of stock option awards and recorded a $38,000 tax benefit from these exercises. Plan participants realized an intrinsic value of $278,000 from the exercise of these stock options during 2012. In comparison, Plan participants realized an intrinsic value of $22,000 and $19,000 from the exercise of stock options during 2011 and 2010, respectively. As of December 31, 2012, the total compensation costs related to nonvested stock options that have not yet been recognized totaled $4,000, and the weighted-average period which these costs are expected to be recognized over is approximately 0.4 years .

There were no stock option awards granted in 2012, 2011, or 2010.

Restricted Stock Units:

Under the Plan, the Company may grant restricted stock unit awards that vest upon the completion of future service requirements or specified performance criteria. The fair value of these awards is equal to the market price of the common stock at the date of the grant. The Company recognizes stock-based compensation expense for these awards over the vesting period, using the straight-line method, based upon the number of awards ultimately expected to vest. Each restricted stock unit entitles the recipient to receive one share of stock on the vesting date. Generally, the restricted stock units vest 25% per year over four years , with the first vesting date being the one-year anniversary of the grant date, or 100% upon the death, disability or retirement of the recipient, or upon change of control (as defined in the Plan) of the Company. If a participant terminates employment prior to the end of the continuous service period, the unearned portion of the stock unit award is forfeited. The Company may also issue awards that vest upon satisfaction of specified performance criteria. For these types of awards, the final measure of compensation cost is based upon the number of shares that ultimately vest considering the performance criteria.

The following is a summary of nonvested restricted stock unit activity for the year ended December 31, 2012:

			Weighted-
			Average
			Grant-Date
	Shares		Fair Value

As of December 31, 2012, the total compensation costs related to nonvested restricted stock units that have not yet been recognized totaled $509,000, and the weighted average period over which these costs are expected to be recognized is approximately 2.6 years.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Value Information:

The Company uses the modified Black-Scholes option pricing model (”Black-Scholes model”) for determining the fair value of stock options issued to employees and directors. The determination of the fair value of share-based payment awards using the Black-Scholes model is impacted by the Company’s stock price on the date of grant as well as several assumptions used as inputs into the model. The assumptions include the risk-free interest rate at grant date, expected stock volatility, expected dividend payout, and expected option life.

The risk-free interest rate assumption is based upon observed interest rates for the expected term of the Company’s stock options. The expected volatility input into the model takes into account the historical volatility of the Company’s stock over the period that it has been publicly traded or the expected term of the option. The expected dividend yield assumption is based upon the Company’s historical dividend payout determined at the date of grant, if any.

Note 14. Earnings per Common Share

Basic per-share amounts are computed by dividing net income (the numerator) by the weighted-average number of common shares outstanding (the denominator). Diluted per share amounts assume issuance of all common stock issuable upon conversion or exercise of other securities, unless the effect is to reduce the loss or increase the income per common share from continuing operations.

Following are the calculations for basic and diluted earnings per common share:

Note 15. Regulatory Capital Requirements and Restrictions on Subsidiary Cash

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

97

MIDWESTONE FINANCIAL GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) 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, as of December 31, 2012 and 2011, that the Company and the Bank met all capital adequacy requirements to which they were subject.

As of December 31, 2012, the most recent notification from the Federal Deposit Insurance Corporation categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since the notification that management believes have changed the Bank’s category. Notwithstanding its compliance with the specified regulatory thresholds, however, the Bank’s board of directors, subsequent to December 31, 2008, adopted a capital policy pursuant to which it will maintain a ratio of Tier 1 capital to total assets of 8% or greater, which ratio is greater than the ratio required to be well capitalized under the regulatory framework for prompt corrective action. This capital policy also provides that the Bank will maintain a ratio of total capital to total risk-weighted assets of at least 10%, which is equal to the threshold for being well capitalized under the regulatory framework for prompt corrective action.

A comparison of the Company’s and the Bank’s capital with the corresponding minimum regulatory requirements is presented below:

The ability of the Company to pay dividends to its shareholders is dependent upon dividends paid by the Bank to the Company. The Bank is subject to certain statutory and regulatory restrictions on the amount of dividends it may pay. In addition, as previously noted, subsequent to December 31, 2008, the Bank’s board of directors adopted a capital policy requiring it to maintain a ratio of Tier 1 capital to total assets of at least 8% and a ratio of total capital to risk-based capital of at least 10%. Maintenance of these ratios also could limit the ability of the Bank to pay dividends to the Company.

The Bank is required to maintain reserve balances in cash on hand or on deposit with Federal Reserve Banks. In 2012 the Company changed the way in which it calculates its required reserves resulting in a material reduction of this requirement. Reserve balances totaled $1.6 million and $12.5 million as of December 31, 2012 and 2011, respectively.

Note 16. Commitments and Contingencies

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

The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. A summary of the Bank’s commitments at December 31, 2012 and 2011, is as follows:

	December 31,
	2012		2011
(in thousands)
Commitments to extend credit	$	287,194	$	200,690
Commitments to sell loans	1,195		1,955
Standby letters of credit	4,619		3,982
Total	$	293,008	$	206,627

The Bank’s exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, crops, livestock, inventory, property and equipment, residential real estate and income-producing commercial properties.

Commitments to sell loans are agreements to sell loans held for sale to third parties at an agreed upon price.

Standby letters of credit are conditional commitments issued 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 loan facilities to customers. The Bank holds collateral, which may include accounts receivable, inventory, property, equipment and income-producing properties, that support those commitments, if deemed necessary. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Bank would be required to fund the commitment. The maximum potential amount of future payments the Bank could be required to make is represented by the contractual amount shown in the summary above. If the commitment is funded, the Bank would be entitled to seek recovery from the customer. At December 31, 2012, 2011 and 2010, amounts recorded as liabilities for the Bank’s potential obligations under these guarantees were $0.2 million, zero, and zero, respectively.

Contingencies: In the normal course of business, the Bank is involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the accompanying consolidated financial statements.

Concentrations of credit risk: Substantially all of the Bank’s loans, commitments to extend credit and standby letters of credit have been granted to customers in the Bank’s market areas. Although the loan portfolio of the Bank is diversified, approximately 67% of the loans are real estate loans and approximately 16% are agriculturally related. The concentrations of credit by type of loan are set forth in Note 3. Commitments to extend credit are primarily related to commercial loans and home equity loans. Standby letters of credit were granted primarily to commercial borrowers. Investments in securities issued by state and political subdivisions involve certain governmental entities within Iowa. Investment securities of Iowa political subdivisions totaled $140.7 million as of December 31, 2012. No individual municipality exceeded $5.0 million.

Note 17. Related Party Transactions

Certain directors of the Company and certain principal officers are customers of, and have banking transactions with, the Bank in the ordinary course of business. Such indebtedness has been incurred on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unrelated persons.

The following is an analysis of the changes in the loans to related parties during the years ended December 31, 2012 and 2011:

	Year Ended December 31,
	2012			2011
(in thousands)
Balance, beginning	$	20,861		$	30,581
Net decrease due to change in related parties	(102		)	(3,342		)
Advances	5,387			2,420
Collections	(4,211		)	(8,798		)
Balance, ending	$	21,935		$	20,861

None of these loans are past due, nonaccrual or restructured to provide a reduction or deferral of interest or principal because of deterioration in the financial position of the borrower. Deposits from these related parties totaled $9.9 million and $10.0 million as of December 31, 2012 and 2011, respectively. Deposits from related parties are accepted subject to the same interest rates and terms as those from nonrelated parties.

The Company has from time to time engaged Neumann Monson, P.C. (“Neumann Monson”), an architectural services firm headquartered in Iowa City for which Mr. Monson is President, Managing Partner and majority owner, to perform architectural and design services with respect to the Company's offices. During 2012, the Company paid Neumann Monson $230,000 for such services. The engagement of Neumann Monson to provide the services described was reviewed by our Audit Committee, which also monitors the level of services by Neumann Monson on a periodic basis. Apart from the approval and monitoring process involving the Audit Committee, Neumann Monson was retained in the ordinary course of business and the Company believes that such services are provided to the Company on terms no less favorable than those that would have been realized in transactions with unaffiliated parties.

Note 18. Estimated Fair Value of Financial Instruments and Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact.

U.S. GAAP requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, U.S. GAAP establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

100

MIDWESTONE FINANCIAL GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

• Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

• Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

• Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

It is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. Market conditions in recent years have led to diminished, and in some cases, non-existent trading in certain of the financial asset classes. The Company is required to use observable inputs, to the extent available, in the fair value estimation process unless that data results from forced liquidations or distressed sales. Despite the Company’s best efforts to maximize the use of relevant observable inputs, the current market environment has diminished the observability of trades and assumptions that have historically been available. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.

Valuation methods for instruments measured at fair value on a recurring basis

Securities Available for Sale - The Company’s investment securities classified as available for sale include: debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies, debt securities issued by state and political subdivisions, mortgage-backed securities, collateralized mortgage obligations, corporate debt securities, and equity securities. Quoted exchange prices are available for equity securities, which are classified as Level 1. The Company utilizes an independent pricing service to obtain the fair value of debt securities. On a quarterly basis, the Company selects a sample of 30 securities from its primary pricing service and compares them to a secondary independent pricing service to validate value. In addition, the Company periodically reviews the pricing methodology utilized by the primary independent service for reasonableness. Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies and mortgage-backed obligations are priced utilizing industry-standard models that consider various assumptions, including time value, yield curves, volatility factors, prepayment speeds, default rates, loss severity, current market and contractual prices for the underlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace and are classified as Level 2. Municipal securities are valued using a type of matrix, or grid, pricing in which securities are benchmarked against the treasury rate based on credit rating. These model and matrix measurements are classified as Level 2 in the fair value hierarchy. On an annual basis, a group of selected municipal securities are priced by a securities dealer and that price is used to verify the primary independent service’s valuation.

The Company classifies its pooled trust preferred collateralized debt obligations as Level 3. The portfolio consists of six investments in collateralized debt obligations backed by pools of trust preferred securities issued by financial institutions and insurance companies. The Company has determined that the observable market data associated with these assets do not represent orderly transactions and reflect forced liquidations or distressed sales. Based on the lack of observable market data, the Company estimated fair value based on the observable data available and reasonable unobservable market data. The Company estimated fair value based on a discounted cash flow model which used appropriately adjusted discount rates reflecting credit and liquidity risks.

Mortgage Servicing Rights - The Company recognizes the rights to service mortgage loans for others on residential real estate loans internally originated and then sold. Mortgage servicing rights are recorded at fair value based on assumptions through a third-party valuation service. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the servicing cost per loan, the discount rate, the escrow float rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Because many of these inputs are unobservable, the valuations are classified as Level 3.

Changes in the fair value of available-for-sale securities are included in other comprehensive income to the extent the changes are not considered other than temporary impairments. Other than temporary impairment tests are performed on a quarterly basis and any decline in the fair value of an individual security below its cost that is deemed to be other than temporary results in a write-down that is reflected directly in the Company’s consolidated statements of operations.

Valuation methods for instruments measured at fair value on a nonrecurring basis

Collateral Dependent Impaired Loans - From time to time, a loan is considered impaired and an allowance for credit losses is established. The specific reserves for collateral dependent impaired loans are based on the fair value of the collateral less estimated costs to sell. The fair value of collateral is determined based on appraisals. In some cases, adjustments are made to the appraised values due to various factors, including age of the appraisal, age of comparables included in the appraisal, and known changes in the market and in the collateral. Because many of these inputs are unobservable, the valuations are classified as Level 3.

Other Real Estate Owned (OREO) - Other real estate owned represents property acquired through foreclosures and settlements of loans. Property acquired is carried at the lower of the carrying amount of the loan at the time of acquisition, or the estimated fair value of the property, less disposal costs. The Company considers third party appraisals as well as independent fair value assessments from real estate brokers or persons involved in selling OREO in determining the fair value of particular properties. Accordingly, the valuation of OREO is subject to significant external and internal judgment. The Company also periodically reviews OREO to determine whether the property continues to be carried at the lower of its recorded book value or fair value of the property, less disposal costs. Because many of these inputs are unobservable, the valuations are classified as Level 3.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

• Cash and cash equivalents, non-interest-bearing demand deposits, federal funds purchased, securities sold under repurchase agreements, and accrued interest are instruments with carrying values that approximate fair value.

• Investment securities available for sale are measured at fair value on a recurring basis. Held to maturity securities are carried at amortized cost. Fair value is based upon quoted prices, if available. If a quoted price is not available, the fair value is obtained from benchmarking the security against similar securities by using a third-party pricing service.

• Loans held for sale are carried at the lower of cost or fair value, with fair value being based on recent observable loan sales. The portfolio has historically consisted primarily of residential real estate loans.

• 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. The Company does record nonrecurring fair value adjustments to loans to reflect (1) partial write-downs and allowances that are based on the observable market price or appraised value of the collateral or (2) the full charge-off of the loan carrying value.

• Loan pool participation carrying values represent the discounted price paid by us to acquire our participation interests in the various loan pool participations purchased, which approximates fair value.

• The fair value of Federal Home Loan Bank stock is estimated at its carrying value and redemption price of $100 per share.

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

• Federal Home Loan Bank borrowings and long-term debt are recorded at historical cost. The fair value of these items is estimated using discounted cash flow analysis, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements.

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

Changes in assumptions or estimation methodologies may have a material effect on these estimated fair values.

Note 19. Variable Interest Entities

MidWestOne has invested in certain participation certificates of loan pools which are purchased, held and serviced by the third-party independent servicing corporation. MidWestOne’s portfolio holds approximately 95% of participation interests in pools of loans owned and serviced by States Resources Corporation (“SRC”), a third-party loan servicing organization in Omaha, Nebraska. SRC’s owner holds the rest. The Company does not have any ownership interest in or exert any control over SRC, and thus it is not included in the consolidated financial statements.

These pools of loans were purchased from large nonaffiliated banking organizations and from the FDIC acting as receiver of failed banks and savings associations. As loan pools were put out for bid (generally in a sealed bid auction) SRC’s due diligence teams evaluated the loans and determined their interest in bidding on the pool. After the due diligence, MidWestOne management reviewed this information and decided if it wished to continue in the process. If the decision to consider a bid was made, SRC conducted additional analysis to determine the appropriate bid price. This analysis involved discounting loan cash flows with adjustments made for expected losses and changes in collateral values as well as targeted rates of return. A cost or investment basis was assigned to each individual loan at cents per dollar (discounted price) based on SRC’s assessment of the recovery potential of each loan.

Once a bid was awarded to SRC, the Company assumed the risk of profit or loss but on a non-recourse basis so the risk is limited to its initial investment. The extent of the risk is also dependent upon: the debtor or guarantor’s financial condition, the possibility that a debtor or guarantor may file for bankruptcy protection, SRC’s ability to locate any collateral and obtain possession, the value of such collateral, and the length of time it takes to realize the recovery either through collection procedures, legal process, or resale of the loans after a restructure.

MIDWESTONE FINANCIAL GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Loan pool participations are shown on the Company’s consolidated balance sheets as a separate asset category. The original carrying value or investment basis of loan pool participations is the discounted price paid by the Company to acquire its interests, which, as noted, is less than the face amount of the underlying loans. MidWestOne’s investment basis is reduced as SRC recovers principal on the loans and remits its share to the Company or as loan balances are written off as uncollectible.

ITEM 9A. CONTROLS AND PROCEDURES.

Disclosure Controls and Procedures

The Company’s management, including the Chief Executive Officer and Chief Financial Officer, evaluated the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, to evaluate the effectiveness of the Company’s disclosure controls and procedures as of December 31, 2012. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal controls over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) that occurred during the quarter ended December 31, 2012 that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting

Management of the Company is responsible for establishing and maintaining effective internal control over financial reporting. Internal control is designed to provide reasonable assurance to the Company’s management and board of directors regarding the preparation of reliable published financial statements. Internal control over financial reporting includes self-monitoring mechanisms, and actions are taken to correct deficiencies as they are identified.

Because of inherent limitations in any system of internal control, no matter how well designed, misstatements due to error or fraud may occur and not be detected, including the possibility of the circumvention or overriding of controls. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Further, because of changes in conditions, internal control effectiveness may vary over time.

Management assessed the Company’s internal control over financial reporting as of December 31, 2012. This assessment was based on criteria for effective internal control over financial reporting described in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, the Chief Executive Officer and Chief Financial Officer assert that the Company maintained effective internal control over financial reporting as of December 31, 2012 based on the specified criteria.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2012, has been audited by KPMG LLP, the independent registered public accounting firm who also has audited the Company’s consolidated financial statements included in this Annual Report on Form 10-K. KPMG LLP’s report on the Company’s internal control over financial reporting appears on the following page.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders

MidWestOne Financial Group, Inc.:

We have audited MidWestOne Financial Group, Inc.’s (the Company) internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’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, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on 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, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included 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 its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness 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, MidWestOne Financial Group, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of MidWestOne Financial Group, Inc. and subsidiaries as as of December 31, 2012 and 2011, and the related consolidated statements of operations, comprehensive income, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2012, and our report dated March 7, 2013 expressed an unqualified opinion on those consolidated financial statements.

5

If the Executive is asked to submit information to an insurance company and if the Executive makes a material misrepresentation in an application for any insurance that may be used by the Corporation to insure any or all of its obligations under this Agreement, and if as a result of that material misrepresentation the insurance company is not required to pay all or any part of the benefits provided under that insurance, the Executive shall forfeit all rights and benefits payable under this Agreement.

On February 6, 2009, the Company issued 16,000 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A (”Preferred Stock”), together with a ten-year warrant to acquire 198,675 shares of common stock, to the U.S. Department of the Treasury (the “Treasury”) under the Capital Purchase Program (the “CPP”) for an aggregate purchase price of $16.0 million. Upon issuance, the fair values of the senior preferred stock and the common stock warrants were computed as if the securities were issued on a stand-alone basis.

On July 6, 2011, the Company announced that it had repurchased the 16,000 shares of Preferred Stock issued to the Treasury under the CPP for an aggregate repurchase price of $16.1 million including accrued interest.

On July 27, 2011, the Company announced that it had repurchased the common stock warrant issued to the Treasury as part of the CPP for $1.0 million. The warrant had allowed Treasury to purchase 198,675 shares of MidWestOne common stock at $12.08 per share.

Related Party Transactions

Certain directors of the Company and certain principal officers are customers of, and have banking transactions with, the Bank in the ordinary course of business. Such indebtedness has been incurred on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unrelated persons.

The following is an analysis of the changes in the loans to related parties during the years ended December 31, 2012 and 2011:

	Year Ended December 31,
	2012			2011
(in thousands)
Balance, beginning	$	20,861		$	30,581
Net decrease due to change in related parties	(102		)	(3,342		)
Advances	5,387			2,420
Collections	(4,211		)	(8,798		)
Balance, ending	$	21,935		$	20,861

None of these loans are past due, nonaccrual or restructured to provide a reduction or deferral of interest or principal because of deterioration in the financial position of the borrower. Deposits from these related parties totaled $9.9 million and $10.0 million as of December 31, 2012 and 2011, respectively. Deposits from related parties are accepted subject to the same interest rates and terms as those from nonrelated parties.

The Company has from time to time engaged Neumann Monson, P.C. (“Neumann Monson”), an architectural services firm headquartered in Iowa City for which Mr. Monson is President, Managing Partner and majority owner, to perform architectural and design services with respect to the Company's offices. During 2012, the Company paid Neumann Monson $230,000 for such services. The engagement of Neumann Monson to provide the services described was reviewed by our Audit Committee, which also monitors the level of services by Neumann Monson on a periodic basis. Apart from the approval and monitoring process involving the Audit Committee, Neumann Monson was retained in the ordinary course of business and the Company believes that such services are provided to the Company on terms no less favorable than those that would have been realized in transactions with unaffiliated parties.

Fair Value, by Balance Sheet Grouping [Table Text Block]

The following presents the carrying amount and estimated fair value of the financial instruments held by the Company at December 31, 2012 and 2011. The information presented is subject to change over time based on a variety of factors. The operations of the Company are managed from a going concern basis and not a liquidation basis. As a result, the ultimate value realized from the financial instruments presented could be substantially different when actually recognized over time through the normal course of operations. Additionally, a substantial portion of the Company’s inherent value is the Bank’s capitalization and franchise value. Neither of these components has been given consideration in the presentation of fair values below.

Principles of Consolidation and Presentation

12 Months Ended

Dec. 31, 2012

Principles of Consolidation and Presentation [Abstract]

Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]

Nature of Business and Significant Accounting Policies

Nature of business: The Company is a bank holding company registered under the Bank Holding Company Act of 1956 that has elected to be a financial holding company. It is headquartered in Iowa City, Iowa and owns 100% of the outstanding common stock of MidWestOne Bank, Iowa City, and 100% of the common stock of MidWestOne Insurance Services, Inc., Oskaloosa, Iowa. MidWestOne Bank (the “Bank”) is also headquartered in Iowa City, Iowa, and provides services to individuals, businesses, governmental units and institutional customers in east central Iowa. The Bank has office locations in Belle Plaine, Burlington, Cedar Falls, Conrad, Coralville, Davenport, Fairfield, Fort Madison, Melbourne, North English, North Liberty, Oskaloosa, Ottumwa, Parkersburg, Pella, Sigourney, Waterloo and West Liberty, Iowa. MidWestOne Insurance Services, Inc. provides personal and business insurance services in Pella, Melbourne and Oskaloosa, Iowa. The Bank is actively engaged in many areas of commercial banking, including: acceptance of demand, savings and time deposits; making commercial, real estate, agricultural and consumer loans, and other banking services tailored for its individual customers. The Wealth Management area of the Bank administers estates, personal trusts, conservatorships, pension and profit-sharing accounts along with providing other management services to customers.

Accounting estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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. The current economic environment has increased the degree of uncertainty inherent in these estimates.

Certain significant estimates: The allowance for loan losses and the fair values of investment securities and other financial instruments involve certain significant estimates made by management. These estimates are reviewed by management routinely and it is reasonably possible that circumstances that exist 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 MidWestOne Financial Group, Inc., a bank holding company, and its wholly-owned subsidiaries which include MidWestOne Bank, a state chartered bank whose primary federal regulator is the Federal Deposit Insurance Corporation, and MidWestOne Insurance Services, Inc. All significant inter-company accounts and transactions have been eliminated in consolidation.

Trust assets, other than cash deposits held by the Bank in a fiduciary or agency capacity for its customers, are not included in the accompanying consolidated financial statements because such accounts are not assets of the Bank.

In the normal course of business, MidWestOne may enter into a transaction with a variable interest entity (“VIE”). VIEs are legal entities whose investors lack the ability to make decisions about the entity’s activities, or whose equity investors do not have the right to receive the residual returns of the entity. The applicable accounting guidance requires MidWestOne to perform ongoing quantitative and qualitative analysis to determine whether it must consolidate the VIE. MidWestOne does not have any ownership interest in or exert any control over the entity, and thus it is not included in the consolidated financial statements. The investment in non-marketable loan participation certificates for which MidWestOne does not have the ability to exert significant influence are accounted for using the cost method.

Presentation of cash flows: For purposes of reporting cash flows, cash and due from banks includes cash on hand, amounts due from banks, and federal funds sold. Cash flows from portfolio loans originated by the Bank, deposits, federal funds purchased, and securities sold under agreements to repurchase are reported net.

Cash receipts and cash payments resulting from acquisitions and sales of loans originated for sale are classified as operating cash flows on a gross basis in the consolidated statements of cash flows.

Investment securities: Certain debt securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Securities not classified as held to maturity, including equity securities with readily determinable fair values, are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income.

The Company carries its investment securities at fair value, and the Company employs valuation techniques which utilize observable inputs when those inputs are available. These observable inputs reflect assumptions market participants would use in pricing the security, developed based on market data obtained from sources independent of the Company. When such information is not available, the Company employs valuation techniques which utilize unobservable inputs, or those which reflect the Company’s own assumptions about market participants, based on the best information available in the circumstances. These valuation methods typically involve cash flow and other financial modeling techniques. Changes in underlying factors, assumptions, estimates, or other inputs to the valuation techniques could have a material impact on the Company’s future financial condition and results of operations. Fair value measurements are required to be classified as Level 1 (quoted prices), Level 2 (based on observable inputs) or Level 3 (based on unobservable inputs) discussed in more detail in Note 18 to the consolidated financial statements. Available for sale securities are recorded at fair value with unrealized gains and losses excluded from earnings and reported as a separate component of shareholders’ equity until realized.

Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Declines in the fair value of held to maturity and available for sale securities below their cost, that are deemed to be other than temporary, are reflected in earnings as realized losses. In determining whether other than temporary impairment exists, management considers whether: (1) we have the intent to sell the security; (2) it is more likely than not that we will be required to sell the security before recovery of the amortized cost basis; and (3) we do not expect to recover the entire amortized cost basis of the security. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.

Loans: Loans are stated at the principal amount outstanding, net of deferred loan fees and costs and allowance for loan losses. Interest on loans is credited to income as earned based on the principal amount outstanding. Deferred loan fees and costs are amortized using the level yield method over the remaining maturities on the loans.

The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due, unless the credit is well secured and in process of collection. Credit card loans and other personal loans are typically charged off no later than 180 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date, if collection of principal or interest is considered doubtful.

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

Loan Pool Participations: The Company acquired its loan pool participations from the Former MidwestOne during the merger and continued in this business following the merger. However, in 2010, the Company made the decision to exit this line of business and is thus not purchasing new loan pool participations as existing pools pay down. The pools consist of loans to borrowers located throughout the United States.

The Company carries its investment in the loan pools as a separate earning asset on the consolidated balance sheets. Principal or interest restructures, write-downs, or write-offs within the pools are not included in the Company’s disclosures for its loan portfolio, and foreclosed property from loans associated with the pools is not included in other real estate owned on the consolidated balance sheets. The loan pool participations are managed by a non-affiliate servicer operating in Omaha, Nebraska.

Each pool has a different composition and different characteristics. The composition of a loan pool is generally determined by the seller based on its desire to maximize the price it receives for all loans among the various pools. Many of the pools consist of loans primarily secured by single-family, multi-family, and small commercial real estate. Some pools may consist of a large number of small consumer loans that are secured by other assets such as automobiles or mobile homes, while other pools may consist of small to medium balance commercial loans. Some may contain a mixture of such loans and other types of loans.

The Company invested in pools consisting of both performing loans and past-due nonperforming loans. The price bid and paid for such a loan pool was determined based on the composition of the particular pool, the amounts the servicer believed could be collected on such a pool, and the risks associated with the collection of such amounts.

Upon the acquisition of a participation interest in a loan pool, the Company assumed the risk of loss on a pro-rata basis. The extent of such risk is dependent on a number of factors, including the servicer’s ability to locate the debtors, the debtors’ financial condition, the possibility that a debtor may file for protection under applicable bankruptcy laws, the servicer’s ability to locate the collateral, if any, for the loan and to obtain possession of such collateral, the value of such collateral, and the length of time it takes to realize the ultimate recovery either through collection procedures or through a resale of the loans following a restructure.

A cost “basis” was assigned to each individual loan acquired on a cents per dollar (discounted price) based on the servicer’s assessment of the recovery potential of each such loan. This methodology assigns a higher basis to performing loans with greater potential collectability and a lower basis to those loans identified as having little or no potential for collection.

Loan pool participations are shown on the Company’s consolidated balance sheets as a separate asset category. The original carrying value of loan pool participations represents the discounted price paid by the Company to acquire its participation interests in various loan pools purchased by the servicer. The Company’s investment balance is reduced as the servicer collects principal payments on the loans and remits the proportionate share of such payments to the Company.

The loan pool participations acquired are accounted for in accordance with the provisions of ASC Topic 310.

ASC Topic 310 provides guidance on the accounting for purchased loans that show evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the purchaser will be unable to collect all contractually required payments receivable. ASC Topic 310 generally requires that the excess of the estimated cash flows expected to be collected on the loan over the initial investment be accreted over the estimated remaining life of loan.

According to the ASC Topic 310, in order to apply the interest method of recognition to these types of loans, there must be sufficient information to reasonably estimate the amount and timing of the cash flows expected to be collected. When that is not the case, the loan should be accounted for as a nonaccrual status applying the cash basis income recognition to the loan.

The Company has developed and implemented procedures to determine if accretion of the discount (“accretable yield”) on the purchased loans in a pool is required under ASC Topic 310. Given the impaired nature of the loan pools typically purchased, the individual loans were evaluated for ASC Topic 310 purposes by the end of a six-month window from the date of purchase. This provided time to assess the quality of the loans and assign basis to each loan within the pool. Purchased loans were evaluated individually with a determination made utilizing various criteria including: past-due status, late payments, legal status of the loan (not in foreclosure, judgment against the borrower, or referred to legal counsel), frequency of payments made, collateral adequacy and the borrower’s financial condition. If all the criteria were met, the Company utilizes the accounting treatment for that individual loan required by ASC Topic 310 with the accretable yield difference between the expected cash flows and the purchased basis accreted into income on the level yield basis over the anticipated life of the loan. If any of the six criteria are not met, the loan is accounted for on the cash-basis of accounting.

In the event that a prepayment is received on a loan accounted for under ASC Topic 310, the accretable yield is recomputed and the revised amount accreted over the estimated remaining life of the loan on the level yield basis. If a loan subject to accretable yield under ASC Topic 310 fails to make timely payments, it is subject to classification and an allowance for loss would be established.

Collection expenses incurred by the servicer are netted against discount income. Discount income is added to interest income and reflected as one amount on the Company’s consolidated statements of operations.

Interest income is only recognized when collected and actually remitted to the Company by the servicer for those loans subject to nonaccrual status in accordance with ASC Topic 310. Many of the pools that have been purchased by the servicer do not include purchased interest in the cost basis; thus, interest collected does not have a cost basis and represents profit. Interest income collected by the servicer is reflected in the Company’s consolidated financial statements as interest income and is included as part of interest and discount on loan pool participations.

Loans held for sale: Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value, as determined by aggregate outstanding commitments from investors or current investor yield requirements. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income.

Mortgage loans held for sale are generally sold with the mortgage servicing rights retained. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price plus the value of servicing rights, less the carrying value of the related mortgage loans sold.

Allowance for loan losses: The allowance for loan losses is established as losses estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a quarterly basis by management and is based upon management’s periodic review of the collectiblity of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available.

The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as doubtful, substandard or special mention. For such loans that are also classified as impaired as well as loans meeting the definition of a troubled debt restructuring, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan are lower than the carrying value of that loan. The general component covers loans not classified as impaired and is based on historical loss experience adjusted for qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects that margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.

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

Large groups of smaller-balance, homogeneous loans are collectively evaluated for impairment. Accordingly, the Bank generally does not separately identify individual consumer and residential loans for impairment unless they meet the definition of a troubled debt restructure.

Transfers of financial assets: Revenue from the origination and sale of loans in the secondary market is recognized upon the transfer of financial assets and 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 Bank and its affiliates; (2) the transferee has the right to pledge or exchange the assets it received and no condition both constrains the transferee from taking advantage of its right to pledge or exchange and provides more than a trivial benefit to the transferor; and (3) the Bank and its affiliates do 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.

Revenue recognition: Trust fees, deposit account service charges and other fees are recognized when payment is received for the services (cash basis), which generally occurs at the time the services are provided.

Credit-related financial instruments: In the ordinary course of business, the Bank 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. The Bank records a liability to the extent losses on its commitments to lend are probable.

Premises and equipment: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. The estimated useful lives and primary method of depreciation for the principal items are as follows:

	Years
Type of Assets	Minimum		Maximum	Depreciation Method
Buildings and leasehold improvements	10	-	30	Straight-line
Furniture and equipment	3	-	10	Straight-line

Charges for maintenance and repairs are expensed as incurred. When assets are retired or disposed of the related cost and accumulated depreciation are removed from the respective accounts and the resulting gain or loss is recorded.

Other real estate owned: Other real estate owned acquired in satisfaction of loans is recorded at the lower of cost or fair value less estimated costs of disposal. When a property is acquired, the excess of the recorded investment in the property over its estimated fair value, less estimated costs of disposal, if any, is charged to the allowance for loan losses.

Subsequent declines in the estimated fair value are recorded in a valuation allowance account. Additions to or reductions from valuation allowances, along with net operating results of the property, are included in other operating expenses.

Mortgage servicing rights: Mortgage servicing rights are recorded at fair value based on assumptions through a third-party valuation service. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the servicing cost per loan, the discount rate, the escrow float rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses.

Bank-owned life insurance: Bank-owned life insurance is carried at cash surrender value, net of surrender and other charges, with increases/decreases reflected as income/expense in the consolidated statements of operations.

Employee benefit plans: Deferred benefits under a salary continuation plan are charged to expense during the period in which the participating employees attain full eligibility.

Stock-based compensation: Compensation expense for share based awards is recorded over the vesting period at the fair value of the award at the time of grant. The exercise price of options or fair value of nonvested shares granted under the Company’s incentive plans is equal to the fair market value of the underlying stock at the grant date. The Company assumes no projected forfeitures on its stock based compensation, since actual historical forfeiture rates on its stock based incentive awards has been negligible.

Income taxes: The Company files a consolidated federal income tax return. Income tax expense is generally allocated as if the Company and its subsidiaries file separate income tax returns. For state purposes, the Bank files a franchise tax return and the remaining entities file a consolidated income tax return. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

There were no material unrecognized tax benefits or any interest or penalties on any unrecognized tax benefits as of December 31, 2012 and 2011.

Any interest and penalties related to income taxes would be recorded as other operating expense in the consolidated statements of operations.

Preferred Stock: On February 6, 2009, the Company issued 16,000 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A (”Preferred Stock”), together with a ten-year warrant to acquire 198,675 shares of common stock, to the U.S. Department of the Treasury (the “Treasury”) under the Capital Purchase Program (the “CPP”) for an aggregate purchase price of $16.0 million. Upon issuance, the fair values of the senior preferred stock and the common stock warrants were computed as if the securities were issued on a stand-alone basis.

On July 6, 2011, the Company announced that it had repurchased the 16,000 shares of Preferred Stock issued to the Treasury under the CPP for an aggregate repurchase price of $16.1 million including accrued interest.

On July 27, 2011, the Company announced that it had repurchased the common stock warrant issued to the Treasury as part of the CPP for $1.0 million. The warrant had allowed Treasury to purchase 198,675 shares of MidWestOne common stock at $12.08 per share.

Common Stock: On July 26, 2011, our Board of Directors authorized the implementation of a share repurchase program to repurchase up to $1.0 million of the Company’s outstanding shares of common stock through December 31, 2011. Pursuant to the program, we repurchased 45,039 shares of common stock during the third quarter of 2011 for an aggregate cost of $658,000. On October 18, 2011, our Board of Directors amended the Company’s share repurchase program by increasing the remaining amount of authorized repurchases to $5.0 million, and extending the expiration of the program to December 31, 2012. For the year of 2012 we repurchased a total of 104,518 shares of common stock at a cost of $1.8 million, with $2.4 million remaining in the current share repurchase program at December 31, 2012 .

On January 15, 2013, the Company's board of directors announced the renewal of the Company's share repurchase program, extending the expiration of the program to December 31, 2014 and increasing the remaining amount of authorized repurchases under the program to $5.0 million from the approximately $2.4 million of authorized repurchases that had previously remained. Pursuant to the program, the Company may continue to repurchase shares from time to time in the open market, and the method, timing and amounts of repurchase will be solely in the discretion of the Company's management. The repurchase program does not require the Company to acquire a specific number of shares. Therefore, the amount of shares repurchased pursuant to the program will depend on several factors, including market conditions, capital and liquidity requirements, and alternative uses for cash available.

Comprehensive income: Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of shareholders’ equity on the consolidated balance sheets, and are disclosed in the consolidated statements of comprehensive income.

The components of accumulated other comprehensive income, included in shareholders’ equity, net of tax, are as follows:

Loans Receivable and the Allowance for Loan Losses [Abstract]

Financing Receivable, Allowance for Credit Losses, Policy for Uncollectible Amounts

The Company requires a loan to be charged-off as soon as it becomes apparent that some loss will be incurred, or when its collectability is sufficiently questionable that it no longer is considered a bankable asset. The primary considerations when determining if and how much of a loan should be charged-off are as follows: (1) the potential for future cash flows; (2) the value of any collateral; and (3) the strength of any co-makers or guarantors.When it is determined that a loan requires partial or full charge-off, a request for approval of a charge-off is submitted to the Bank’s President, Executive Vice President of Lending, and the Senior Regional Loan officer. The Bank’s Board of Directors formally approves all loan charge-offs at the next regularly scheduled meeting. Once a loan is charged-off, it cannot be restructured and returned to the Bank’s books.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]

The allowance for loan losses is established as losses estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a quarterly basis by management and is based upon management’s periodic review of the collectiblity of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available.

The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as doubtful, substandard or special mention. For such loans that are also classified as impaired as well as loans meeting the definition of a troubled debt restructuring, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan are lower than the carrying value of that loan. The general component covers loans not classified as impaired and is based on historical loss experience adjusted for qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects that margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.

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

Large groups of smaller-balance, homogeneous loans are collectively evaluated for impairment. Accordingly, the Bank generally does not separately identify individual consumer and residential loans for impairment

The Company requires the maintenance of an adequate allowance for loan and lease losses (“ALLL”) in order to cover probable losses without eroding the Company’s capital base. Calculations are done at each quarter end, or more frequently if warranted, to analyze the collectability of loans and to ensure the adequacy of the allowance. In line with FDIC directives, the ALLL calculation does not include consideration of loans held for sale or off-balance-sheet credit exposures (such as unfunded letters of credit). Determining the appropriate level for the ALLL relies on the informed judgment of management, and as such, is subject to inaccuracy. Given the inherently imprecise nature of calculating the necessary ALLL, the Company’s policy permits an “unallocated” allowance between 15% above and 5% below the “indicated reserve.” These unallocated amounts are present due to the inherent imprecision in the ALLL calculation.

Earnings per Common Share [Abstract]

Earnings Per Share Disclosure [Text Block]

Earnings per Common Share

Basic per-share amounts are computed by dividing net income (the numerator) by the weighted-average number of common shares outstanding (the denominator). Diluted per share amounts assume issuance of all common stock issuable upon conversion or exercise of other securities, unless the effect is to reduce the loss or increase the income per common share from continuing operations.

Following are the calculations for basic and diluted earnings per common share:

Commitments and Contingencies

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

The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. A summary of the Bank’s commitments at December 31, 2012 and 2011, is as follows:

	December 31,
	2012		2011
(in thousands)
Commitments to extend credit	$	287,194	$	200,690
Commitments to sell loans	1,195		1,955
Standby letters of credit	4,619		3,982
Total	$	293,008	$	206,627

The Bank’s exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, crops, livestock, inventory, property and equipment, residential real estate and income-producing commercial properties.

Commitments to sell loans are agreements to sell loans held for sale to third parties at an agreed upon price.

Standby letters of credit are conditional commitments issued 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 loan facilities to customers. The Bank holds collateral, which may include accounts receivable, inventory, property, equipment and income-producing properties, that support those commitments, if deemed necessary. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Bank would be required to fund the commitment. The maximum potential amount of future payments the Bank could be required to make is represented by the contractual amount shown in the summary above. If the commitment is funded, the Bank would be entitled to seek recovery from the customer. At December 31, 2012, 2011 and 2010, amounts recorded as liabilities for the Bank’s potential obligations under these guarantees were $0.2 million, zero, and zero, respectively.

Contingencies: In the normal course of business, the Bank is involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the accompanying consolidated financial statements.

Concentrations of credit risk: Substantially all of the Bank’s loans, commitments to extend credit and standby letters of credit have been granted to customers in the Bank’s market areas. Although the loan portfolio of the Bank is diversified, approximately 67% of the loans are real estate loans and approximately 16% are agriculturally related. The concentrations of credit by type of loan are set forth in Note 3. Commitments to extend credit are primarily related to commercial loans and home equity loans. Standby letters of credit were granted primarily to commercial borrowers. Investments in securities issued by state and political subdivisions involve certain governmental entities within Iowa. Investment securities of Iowa political subdivisions totaled $140.7 million as of December 31, 2012. No individual municipality exceeded $5.0 million.

In connection with the Company’s merger with the Former MidWestOne in March 2008, the Company acquired $15.6 million in long-term subordinated debt from the Former MidwestOne’s issuance of a pooled trust preferred security. The junior subordinated debentures supporting the trust preferred securities have a maturity date of December 15, 2042, do not require any principal amortization and were callable on December 15, 2012 at par at the Company’s option. The interest rate was fixed on $7.8 million of the debt until December 15, 2012, at an interest rate of 6.48%, after which the rate became variable, as is the case with the remaining balance of the debt. The variable rate is based on the three month LIBOR rate plus 1.59% with interest payable quarterly. At December 31, 2012, the interest rate was at 1.90%. During the year the interest rate ranged from 4.31% to 1.90%. Interest expense recorded during 2012 and 2011 was $0.7 million and $0.7 million, respectively.

Loan Portfolio Segment Risk Characteristics

Agricultural - Agricultural loans, most of which are secured by crops, livestock, and machinery, are provided to finance capital improvements and farm operations as well as acquisitions of livestock and machinery. The ability of the borrower to repay may be affected by many factors outside of the borrower’s control including adverse weather conditions, loss of livestock due to disease or other factors, declines in market prices for agricultural products and the impact of government regulations. The ultimate repayment of agricultural loans is dependent upon the profitable operation or management of the agricultural entity. Collateral for these loans generally includes accounts receivable, inventory, equipment and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business.

Commercial and Industrial - Commercial and industrial loans are primarily made based on the reported cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The collateral support provided by the borrower for most of these loans and the probability of repayment is based on the liquidation of the pledged collateral and enforcement of a personal guarantee, if any exists. The primary repayment risks of commercial and financial loans are that the cash flows of the borrower may be unpredictable, and the collateral securing these loans may fluctuate in value. The size of the loans the Company can offer to commercial customers is less than the size of the loans that competitors with larger lending limits can offer. This may limit the Company’s ability to establish relationships with the area’s largest businesses. As a result, the Company may assume greater lending risks than financial institutions that have a lesser concentration of such loans and tend to make loans to larger businesses. Collateral for these loans generally includes accounts receivable, inventory, equipment and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business. In addition, if the United States economy does not meaningfully improve, this could harm or continue to harm, as the case may be, the businesses of our commercial and industrial customers and reduce the value of the collateral securing these loans.

Commercial Real Estate - The Company offers mortgage loans to commercial and agricultural customers for the acquisition of real estate used in their business, such as offices, warehouses and production facilities, and to real estate investors for the acquisition of apartment buildings, retail centers, office buildings and other commercial buildings. The market value of real estate securing commercial real estate loans can fluctuate significantly in a short period of time as a result of market conditions in the geographic area in which the real estate is located. Adverse developments affecting real estate values in one or more of the Company’s markets could increase the credit risk associated with its loan portfolio. Additionally, real estate lending typically involves higher loan principal amounts and the repayment of the loans generally is dependent, in large part, on sufficient income from the properties securing the loans to cover operating expenses and debt service. Economic events or governmental regulations outside of the control of the borrower or lender could negatively impact the future cash flow and market values of the affected properties.

Residential Real Estate - The Company generally retains short-term residential mortgage loans that are originated for its own portfolio but sells most long-term loans to other parties while retaining servicing rights on the majority of such loans. The market value of real estate securing residential real estate loans can fluctuate as a result of market conditions in the geographic area in which the real estate is located. Adverse developments affecting real estate values in one or more of the Company’s markets could increase the credit risk associated with its loan portfolio. Additionally, real estate lending typically involves higher loan principal amounts and the repayment of the loans generally is dependent, in large part, on the borrower’s continuing financial stability, and are therefore more likely to be affected by adverse personal circumstances.

Consumer - Consumer loans typically have shorter terms, lower balances, higher yields and higher risks of default.  Consumer loan collections are dependent on the borrower’s continuing financial stability, and are therefore more likely to be affected by adverse personal circumstances. Collateral for these loans generally includes automobiles, boats, recreational vehicles, mobile homes, and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to recover and may fluctuate in value based on condition. In addition, a decline in the United States economy could result in reduced employment, impacting the ability of customers to repay their obligations.

Loans acquired with deteriorated credit quality (loan pool participations) - The underlying loans in the loan pool participations include both fixed-rate and variable-rate instruments. No amounts for interest due are reflected in the carrying value of the loan pool participations. Based on historical experience, the average period of collectibility for loans underlying loan pool participations, many of which have exceeded contractual maturity dates, is approximately three to five years. Loan pool balances are affected by the payment and refinancing activities of the borrowers resulting in pay-offs of the underlying loans and reduction in the balances. Collections from the individual borrowers are managed by the loan pool servicer and are affected by the borrower’s financial ability and willingness to pay, foreclosure and legal action, collateral value, and the economy in general.

Charge-off Policy

The Company requires a loan to be charged-off as soon as it becomes apparent that some loss will be incurred, or when its collectability is sufficiently questionable that it no longer is considered a bankable asset. The primary considerations when determining if and how much of a loan should be charged-off are as follows: (1) the potential for future cash flows; (2) the value of any collateral; and (3) the strength of any co-makers or guarantors.

When it is determined that a loan requires partial or full charge-off, a request for approval of a charge-off is submitted to the Bank’s President, Executive Vice President of Lending, and the Senior Regional Loan officer. The Bank’s Board of Directors formally approves all loan charge-offs at the next regularly scheduled meeting. Once a loan is charged-off, it cannot be restructured and returned to the Bank’s books.

The Allowance for Loan and Lease Losses - Bank Loans

The Company requires the maintenance of an adequate allowance for loan and lease losses (“ALLL”) in order to cover probable losses without eroding the Company’s capital base. Calculations are done at each quarter end, or more frequently if warranted, to analyze the collectability of loans and to ensure the adequacy of the allowance. In line with FDIC directives, the ALLL calculation does not include consideration of loans held for sale or off-balance-sheet credit exposures (such as unfunded letters of credit). Determining the appropriate level for the ALLL relies on the informed judgment of management, and as such, is subject to inaccuracy. Given the inherently imprecise nature of calculating the necessary ALLL, the Company’s policy permits an “unallocated” allowance between 15% above and 5% below the “indicated reserve.” These unallocated amounts are present due to the inherent imprecision in the ALLL calculation.

Loans Reviewed Individually for Impairment

The Company identifies loans to be reviewed and evaluated individually for impairment, based on current information and events, and the probability that the borrower will be unable to repay all amounts due according to the contractual terms of the loan agreement. Specific areas of consideration include: size of credit exposure, risk rating, delinquency, nonaccrual status, and loan classification.

The level of individual impairment is measured using one of the following methods: (1) the fair value of the collateral less costs to sell; (2) the present value of expected future cash flows, discounted at the loan’s effective interest rate; or (3) the loan’s observable market price. Loans that are deemed fully collateralized or have been charged down to a level corresponding with any three of the measurements require no assignment of reserves from the ALLL.

All loans deemed troubled debt restructure or “TDR” are considered impaired. A loan is considered a TDR when the Bank, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that the Bank would not otherwise consider. All of the following factors are indicators that the Bank has granted a concession (one or multiple items may be present):

• The borrower receives a reduction of the stated interest rate for the remaining original life of the debt.

• The borrower receives an extension of the maturity date or dates at a stated interest rate lower that the current market interest rate for new debt with similar risk characteristics.

• The borrower receives a reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement.

• The borrower receives a deferral of required payments (principal and/or interest).

• The borrower receives a reduction of the accrued interest.

The following table sets forth information on the Company’s troubled debt restructurings by class of financing receivable occurring during the stated periods:

During the year ended December 31, 2012 four loans were classified as new troubled debt restructures (TDR). One commercial and industrial loan was added to the TDR loan classification due to being extended and re-amortized to a longer period. This credit also experienced a payment default during 2012. Two farmland loans, both to the same borrower, were classified as new TDRs during 2012 due to a court ordered interest rate reduction in connection with a Chapter 12 bankruptcy. One one- to four- family junior lien was granted a rate concession and advanced additional funds for taxes and insurance due to borrower financial difficulties during 2012.

During the year ended December 31, 2011, one commercial and industrial loan was added to the TDR loan classification due to a partial charge-off of its outstanding principal and an adjustment to its terms granting a below market interest rate. Likewise, one construction and development loan was also added due to a partial balance charge-off and interest rate concession. Four commercial real estate loans, all to the same borrower, were classified as new TDRs during 2011 due to the extension of a forbearance agreement and the granting of a below market interest rate. These four credits also experienced a payment default during 2011. One commercial real estate loan that was a new TDR during 2011 due to a below market interest rate was on non-accrual at year-end. One- to four- family first lien restructures increased by one loan due to an interest rate concession. A commercial real estate loan TDR that was on non-accrual at December 31, 2010, was rewritten with a rate concession and had additional funds advanced in 2011, and was reported as a new TDR in 2011.

During the year ended December 31, 2010, two agricultural loans had been added to the restructured classification due to the modification of loan guarantees, a charge-off of $500,000, and both notes being at below market interest rates with interest-only payments being required. One farmland loan related to the agricultural credits was also classified as a TDR due to having the interest rate modified to a below market rate. One commercial real estate loan became a TDR due to an interest rate concession. One residential real estate first lien was identified as a TDR in 2010, having been granted a below market interest rate with normally required private mortgage insurance being waived. It was considered a workout situation by management. Finally, one home equity loan was designated a TDR due to a partial charge-off of the principal balance.

Loans by class of financing receivable modified as TDRs within the previous 12 months and for which there was a payment default during the stated periods were:

Loans Reviewed Collectively for Impairment

All loans not evaluated individually for impairment are grouped together by type (i.e. commercial, agricultural, consumer, etc.) and further segmented within each subset by risk classification (i.e. pass, special mention, and substandard). Homogeneous loans past due 60-89 days and 90+ days, are classified special mention and substandard, respectively, for allocation purposes.

The Company’s historical loss experience for each loan type is calculated using the fiscal quarter-end data for the most recent 20 quarters as a starting point for estimating losses. In addition, other prevailing qualitative or environmental factors likely to cause probable losses to vary from historical data are incorporated in the form of adjustments to increase or decrease the loss rate applied to each group. These adjustments are documented, and fully explain how the current information, events, circumstances, and conditions impact the historical loss measurement assumptions.

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

• Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses.

• Changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments.

• Changes in the nature and volume of the portfolio and in the terms of loans.

• Changes in the experience, ability and depth of lending management and other relevant staff.

• Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans.

• Changes in the quality of our loan review system.

• Changes in the value of underlying collateral for collateral-dependent loans.

• The existence and effect of any concentrations of credit, and changes in the level of such concentrations.

• The effect of other external factors, such as competition and legal and regulatory requirements, on the level of estimated credit losses in the Bank’s existing portfolio.

The items listed above are used to determine the pass percentage for loans evaluated collectively and, as such, are applied to the loans risk rated pass. Due to the inherent risks associated with special mention risk rated loans (i.e., early stages of financial deterioration, technical exceptions, etc.), this subset is reserved at two times the pass allocation factor to reflect this increased risk exposure. In addition, non-impaired loans classified as substandard loans carry exponentially greater risk than special mention loans, and as such, this subset is reserved at six times the pass allocation. Further, non-impaired loans identified as substandard “performing collateral deficient” are reserved at 12 times the pass allocation due to the perceived additional risk for such credits.

The Allowance for Loan and Lease Losses - Loan Pool Participations

The Company requires that the loan pool participation ALLL will be at least sufficient to cover the next quarter’s estimated charge-offs as presented by the servicer. Currently, charge-offs are netted against the income the Company receives, thus the balance in the loan pool reserve is not affected and remains stable. In essence, a provision for loan losses is made that is equal to the quarterly charge-offs, which is deducted from income received from the loan pools. By maintaining a sufficient reserve to cover the next quarter’s charge-offs, the Company will have sufficient reserves in place should no income be collected from the loan pools during the quarter. In the event the estimated charge-offs provided by the servicer are greater than the loan pool ALLL, an additional provision is made to cover the difference between the current ALLL and the estimated charge-offs provided by the servicer.

Loans Reviewed Individually for Impairment

The loan servicer reviews the portfolio quarterly on a loan-by-loan basis, and loans that are deemed to be impaired are charged-down to their estimated value during the next calendar quarter. All loans that are to be charged-down are reserved against in the ALLL adequacy calculation. Loans that continue to have an investment basis that have been charged-down are monitored, and if additional impairment is noted the reserve requirement is increased on the individual loan.

Loans Reviewed Collectively for Impairment

The Company utilizes the annualized average of portfolio loan (not loan pool) historical loss per risk category over a two year period of time. Supporting documentation for the technique used to develop the historical loss rate for each group of loans is required to be maintained. It is management’s assessment that the two year rate is most reflective of the estimated credit losses in the current loan pool portfolio.

The following table sets forth the composition of the Company’s loans and loan pool participations by internally assigned credit quality indicators at December 31, 2012 and 2011:

Special Mention - A special mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.

Substandard - Substandard loans are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected.

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

Loss - Loans classified loss are generally considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be effected in the future.

Non-accrual and Delinquent Loans

Loans are placed on non-accrual when (1) payment in full of principal and interest is no longer expected or (2) principal or interest has been in default for 90 days or more (unless the loan is both well secured with marketable collateral and in the process of collection). All loans rated doubtful or worse are placed on non-accrual.

A non-accrual asset may be restored to an accrual status when (1) all past due principal and interest has been paid (excluding renewals and modifications that involve the capitalizing of interest) or (2) the loan becomes well secured and is in the process of collection. An established track record of performance is also considered when determining accrual status.

Delinquency status of a loan is determined by the number of days that have elapsed past the loan’s payment due date, using the following classification groupings: 30-59 days, 60-89 days and 90 days or more.

The following table sets forth the composition of the Company’s recorded investment in loans on nonaccrual status as of December 31, 2012 and 2011:

Loan Pool Participations

ASC Topic 310 addresses accounting for differences between contractual cash flows and cash flows expected to be collected from an investor’s initial investment in loans or debt securities acquired in a transfer if those differences are attributable, at least in part, to credit quality. The loans underlying the loan pool participations were evaluated individually when purchased for application of ASC Topic 310, utilizing various criteria including: past-due status, late payments, legal status of the loan (not in foreclosure, judgment against the borrower, or referred to legal counsel), frequency of payments made, collateral adequacy and the borrower’s financial condition. If all the criteria were met, the individual loan utilized the accounting treatment required by ASC Topic 310 with the accretable yield difference between the expected cash flows and the purchased basis accreted into income on the level yield basis over the anticipated life of the loan. If any of the six criteria were not met at the time of purchase, the loan was accounted for on the cash basis of accounting.

The loan servicer reviews the portfolio quarterly on a loan-by-loan basis, and loans that are deemed to be impaired are charged-down to their estimated value. As of December 31, 2012, approximately 65% of the loans were contractually current or less than 90 days past due, while 35% were contractually past due 90 days or more. Many of the loans were acquired in a contractually past due status, which is reflected in the discounted purchase price of the loans. Performance status is monitored on a monthly basis. The 35% contractually past due includes loans in litigation and foreclosed property.

The Company evaluated all loans under the ASC Topic 310 criteria as of December 31, 2012 and 2011 and determined that certain loans did not meet the criteria for level-yield income recognition required by ASC Topic 310. The outstanding balance of those loans was $98.3 million with a carrying value of $32.5 million as of December 31, 2012, and $120.4 million and $45.7 million, respectively, as of December 31, 2011. Income from these loans is realized on a cash basis, or when payments are actually received from the borrower.

The outstanding balances and carrying values as of December 31, 2012 and 2011, of the loans purchased that met the level-yield income recognition criteria under ASC Topic 310 are as follows:

Regulatory Capital Requirements and Restrictions on Subsidiary Cash

Regulatory Capital Requirements and Restrictions on Subsidiary Cash [Abstract]

Regulatory Capital Requirements under Banking Regulations [Text Block]

Regulatory Capital Requirements and Restrictions on Subsidiary Cash

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

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) 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, as of December 31, 2012 and 2011, that the Company and the Bank met all capital adequacy requirements to which they were subject.

As of December 31, 2012, the most recent notification from the Federal Deposit Insurance Corporation categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since the notification that management believes have changed the Bank’s category. Notwithstanding its compliance with the specified regulatory thresholds, however, the Bank’s board of directors, subsequent to December 31, 2008, adopted a capital policy pursuant to which it will maintain a ratio of Tier 1 capital to total assets of 8% or greater, which ratio is greater than the ratio required to be well capitalized under the regulatory framework for prompt corrective action. This capital policy also provides that the Bank will maintain a ratio of total capital to total risk-weighted assets of at least 10%, which is equal to the threshold for being well capitalized under the regulatory framework for prompt corrective action.

A comparison of the Company’s and the Bank’s capital with the corresponding minimum regulatory requirements is presented below:

The ability of the Company to pay dividends to its shareholders is dependent upon dividends paid by the Bank to the Company. The Bank is subject to certain statutory and regulatory restrictions on the amount of dividends it may pay. In addition, as previously noted, subsequent to December 31, 2008, the Bank’s board of directors adopted a capital policy requiring it to maintain a ratio of Tier 1 capital to total assets of at least 8% and a ratio of total capital to risk-based capital of at least 10%. Maintenance of these ratios also could limit the ability of the Bank to pay dividends to the Company.

The Bank is required to maintain reserve balances in cash on hand or on deposit with Federal Reserve Banks. In 2012 the Company changed the way in which it calculates its required reserves resulting in a material reduction of this requirement. Reserve balances totaled $1.6 million and $12.5 million as of December 31, 2012 and 2011, respectively.

The Company has recorded a deferred tax asset for the future tax benefits of Iowa net operating loss carry forwards and certain impairment losses on investment securities. The Iowa net operating loss carry forwards amounting to approximately $34.6 million will expire in various amounts from 2018 to 2032. As of December 31, 2012 and 2011, the Company believed it was more likely than not that all temporary differences associated with the Iowa corporate tax return, as well as certain impairment and capital losses on securities at the federal and state level, would not be fully realized. Accordingly, the Company has recorded a valuation allowance to reduce the net operating loss carry forwards and certain impairment losses on securities. A valuation allowance related to the remaining deferred tax assets has not been provided because management believes it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets.

The Company had no material unrecognized tax benefits as of December 31, 2012 and 2011.

Intangible Assets

Intangible assets decreased to $9.5 million as of December 31, 2012, from $10.2 million as of December 31, 2011, as a result of normal amortization. Amortization of intangible assets is recorded using an accelerated method based on the estimated useful life of the core deposit intangible, customer list intangible and insurance agency intangible. Projections of amortization expense are based on existing asset balances and the remaining useful lives.

The trade name intangible is not amortized but is evaluated for impairment annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. No impairment was recorded on this asset in 2012, 2011, or 2010.

The following table summarizes the amounts and carrying values of intangible assets as of December 31, 2012 and 2011:

The components of the Company’s other assets as of December 31, 2012 and 2011 were as follows:

	As of December 31,
	2012		2011
(in thousands)
Federal Home Loan Bank Stock	$	11,087	$	12,218
Prepaid expenses	5,211		5,961
Mortgage servicing rights	1,484		1,265
Accounts receivable & other miscellaneous assets	2,600		2,218
	$	20,382	$	21,662

The Bank is a member of The Federal Home Loan Bank of Des Moines, and ownership of FHLB stock is a requirement for membership in the FHLB Des Moines. The amount of FHLB stock the Bank is required to hold is directly related to the amount of FHLB advances borrowed. Because this security is not readily marketable and there are no available market values, this security is carried at cost and evaluated for potential impairment each quarter. Redemption of this investment is at the option of the FHLB.

Mortgage servicing rights are recorded at fair value based on a third-party valuation service. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the servicing cost per loan, the discount rate, the escrow float rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses.

Nature of Business and Significant Accounting Policies Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2012

Accounting Policies [Abstract]

Use of Estimates, Policy [Policy Text Block]

Accounting estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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. The current economic environment has increased the degree of uncertainty inherent in these estimates.

Certain significant estimates: The allowance for loan losses and the fair values of investment securities and other financial instruments involve certain significant estimates made by management. These estimates are reviewed by management routinely and it is reasonably possible that circumstances that exist may change in the near-term future and that the effect could be material to the consolidated financial statements.

Consolidation, Policy [Policy Text Block]

The consolidated financial statements include the accounts of MidWestOne Financial Group, Inc., a bank holding company, and its wholly-owned subsidiaries which include MidWestOne Bank, a state chartered bank whose primary federal regulator is the Federal Deposit Insurance Corporation, and MidWestOne Insurance Services, Inc. All significant inter-company accounts and transactions have been eliminated in consolidation.

Trust assets, other than cash deposits held by the Bank in a fiduciary or agency capacity for its customers, are not included in the accompanying consolidated financial statements because such accounts are not assets of the Bank.

In the normal course of business, MidWestOne may enter into a transaction with a variable interest entity (“VIE”). VIEs are legal entities whose investors lack the ability to make decisions about the entity’s activities, or whose equity investors do not have the right to receive the residual returns of the entity. The applicable accounting guidance requires MidWestOne to perform ongoing quantitative and qualitative analysis to determine whether it must consolidate the VIE. MidWestOne does not have any ownership interest in or exert any control over the entity, and thus it is not included in the consolidated financial statements. The investment in non-marketable loan participation certificates for which MidWestOne does not have the ability to exert significant influence are accounted for using the cost method.

Cash and Cash Equivalents, Policy [Policy Text Block]

For purposes of reporting cash flows, cash and due from banks includes cash on hand, amounts due from banks, and federal funds sold. Cash flows from portfolio loans originated by the Bank, deposits, federal funds purchased, and securities sold under agreements to repurchase are reported net.

Marketable Securities, Held-to-maturity Securities, Policy [Policy Text Block]

Certain debt securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Securities not classified as held to maturity, including equity securities with readily determinable fair values, are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income.

Marketable Securities, Available-for-sale Securities, Policy [Policy Text Block]

The Company carries its investment securities at fair value, and the Company employs valuation techniques which utilize observable inputs when those inputs are available. These observable inputs reflect assumptions market participants would use in pricing the security, developed based on market data obtained from sources independent of the Company. When such information is not available, the Company employs valuation techniques which utilize unobservable inputs, or those which reflect the Company’s own assumptions about market participants, based on the best information available in the circumstances. These valuation methods typically involve cash flow and other financial modeling techniques. Changes in underlying factors, assumptions, estimates, or other inputs to the valuation techniques could have a material impact on the Company’s future financial condition and results of operations. Fair value measurements are required to be classified as Level 1 (quoted prices), Level 2 (based on observable inputs) or Level 3 (based on unobservable inputs) discussed in more detail in Note 18 to the consolidated financial statements. Available for sale securities are recorded at fair value with unrealized gains and losses excluded from earnings and reported as a separate component of shareholders’ equity until realized.

Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Declines in the fair value of held to maturity and available for sale securities below their cost, that are deemed to be other than temporary, are reflected in earnings as realized losses. In determining whether other than temporary impairment exists, management considers whether: (1) we have the intent to sell the security; (2) it is more likely than not that we will be required to sell the security before recovery of the amortized cost basis; and (3) we do not expect to recover the entire amortized cost basis of the security. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.

Finance, Loan and Lease Receivables, Held-for-investment, Policy [Policy Text Block]

Loans are stated at the principal amount outstanding, net of deferred loan fees and costs and allowance for loan losses. Interest on loans is credited to income as earned based on the principal amount outstanding. Deferred loan fees and costs are amortized using the level yield method over the remaining maturities on the loans.

The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due, unless the credit is well secured and in process of collection. Credit card loans and other personal loans are typically charged off no later than 180 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date, if collection of principal or interest is considered doubtful.

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

Loan Pool Participations [Policy Text Block]

The Company acquired its loan pool participations from the Former MidwestOne during the merger and continued in this business following the merger. However, in 2010, the Company made the decision to exit this line of business and is thus not purchasing new loan pool participations as existing pools pay down. The pools consist of loans to borrowers located throughout the United States.

The Company carries its investment in the loan pools as a separate earning asset on the consolidated balance sheets. Principal or interest restructures, write-downs, or write-offs within the pools are not included in the Company’s disclosures for its loan portfolio, and foreclosed property from loans associated with the pools is not included in other real estate owned on the consolidated balance sheets. The loan pool participations are managed by a non-affiliate servicer operating in Omaha, Nebraska.

Each pool has a different composition and different characteristics. The composition of a loan pool is generally determined by the seller based on its desire to maximize the price it receives for all loans among the various pools. Many of the pools consist of loans primarily secured by single-family, multi-family, and small commercial real estate. Some pools may consist of a large number of small consumer loans that are secured by other assets such as automobiles or mobile homes, while other pools may consist of small to medium balance commercial loans. Some may contain a mixture of such loans and other types of loans.

The Company invested in pools consisting of both performing loans and past-due nonperforming loans. The price bid and paid for such a loan pool was determined based on the composition of the particular pool, the amounts the servicer believed could be collected on such a pool, and the risks associated with the collection of such amounts.

Upon the acquisition of a participation interest in a loan pool, the Company assumed the risk of loss on a pro-rata basis. The extent of such risk is dependent on a number of factors, including the servicer’s ability to locate the debtors, the debtors’ financial condition, the possibility that a debtor may file for protection under applicable bankruptcy laws, the servicer’s ability to locate the collateral, if any, for the loan and to obtain possession of such collateral, the value of such collateral, and the length of time it takes to realize the ultimate recovery either through collection procedures or through a resale of the loans following a restructure.

A cost “basis” was assigned to each individual loan acquired on a cents per dollar (discounted price) based on the servicer’s assessment of the recovery potential of each such loan. This methodology assigns a higher basis to performing loans with greater potential collectability and a lower basis to those loans identified as having little or no potential for collection.

Loan pool participations are shown on the Company’s consolidated balance sheets as a separate asset category. The original carrying value of loan pool participations represents the discounted price paid by the Company to acquire its participation interests in various loan pools purchased by the servicer. The Company’s investment balance is reduced as the servicer collects principal payments on the loans and remits the proportionate share of such payments to the Company.

The loan pool participations acquired are accounted for in accordance with the provisions of ASC Topic 310.

ASC Topic 310 provides guidance on the accounting for purchased loans that show evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the purchaser will be unable to collect all contractually required payments receivable. ASC Topic 310 generally requires that the excess of the estimated cash flows expected to be collected on the loan over the initial investment be accreted over the estimated remaining life of loan.

According to the ASC Topic 310, in order to apply the interest method of recognition to these types of loans, there must be sufficient information to reasonably estimate the amount and timing of the cash flows expected to be collected. When that is not the case, the loan should be accounted for as a nonaccrual status applying the cash basis income recognition to the loan.

The Company has developed and implemented procedures to determine if accretion of the discount (“accretable yield”) on the purchased loans in a pool is required under ASC Topic 310. Given the impaired nature of the loan pools typically purchased, the individual loans were evaluated for ASC Topic 310 purposes by the end of a six-month window from the date of purchase. This provided time to assess the quality of the loans and assign basis to each loan within the pool. Purchased loans were evaluated individually with a determination made utilizing various criteria including: past-due status, late payments, legal status of the loan (not in foreclosure, judgment against the borrower, or referred to legal counsel), frequency of payments made, collateral adequacy and the borrower’s financial condition. If all the criteria were met, the Company utilizes the accounting treatment for that individual loan required by ASC Topic 310 with the accretable yield difference between the expected cash flows and the purchased basis accreted into income on the level yield basis over the anticipated life of the loan. If any of the six criteria are not met, the loan is accounted for on the cash-basis of accounting.

In the event that a prepayment is received on a loan accounted for under ASC Topic 310, the accretable yield is recomputed and the revised amount accreted over the estimated remaining life of the loan on the level yield basis. If a loan subject to accretable yield under ASC Topic 310 fails to make timely payments, it is subject to classification and an allowance for loss would be established.

Collection expenses incurred by the servicer are netted against discount income. Discount income is added to interest income and reflected as one amount on the Company’s consolidated statements of operations.

Interest income is only recognized when collected and actually remitted to the Company by the servicer for those loans subject to nonaccrual status in accordance with ASC Topic 310. Many of the pools that have been purchased by the servicer do not include purchased interest in the cost basis; thus, interest collected does not have a cost basis and represents profit. Interest income collected by the servicer is reflected in the Company’s consolidated financial statements as interest income and is included as part of interest and discount on loan pool participations.

Finance, Loan and Lease Receivables, Held-for-sale, Policy [Policy Text Block]

Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value, as determined by aggregate outstanding commitments from investors or current investor yield requirements. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income.

Mortgage loans held for sale are generally sold with the mortgage servicing rights retained. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price plus the value of servicing rights, less the carrying value of the related mortgage loans sold.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]

The allowance for loan losses is established as losses estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a quarterly basis by management and is based upon management’s periodic review of the collectiblity of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available.

The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as doubtful, substandard or special mention. For such loans that are also classified as impaired as well as loans meeting the definition of a troubled debt restructuring, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan are lower than the carrying value of that loan. The general component covers loans not classified as impaired and is based on historical loss experience adjusted for qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects that margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.

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

Large groups of smaller-balance, homogeneous loans are collectively evaluated for impairment. Accordingly, the Bank generally does not separately identify individual consumer and residential loans for impairment

The Company requires the maintenance of an adequate allowance for loan and lease losses (“ALLL”) in order to cover probable losses without eroding the Company’s capital base. Calculations are done at each quarter end, or more frequently if warranted, to analyze the collectability of loans and to ensure the adequacy of the allowance. In line with FDIC directives, the ALLL calculation does not include consideration of loans held for sale or off-balance-sheet credit exposures (such as unfunded letters of credit). Determining the appropriate level for the ALLL relies on the informed judgment of management, and as such, is subject to inaccuracy. Given the inherently imprecise nature of calculating the necessary ALLL, the Company’s policy permits an “unallocated” allowance between 15% above and 5% below the “indicated reserve.” These unallocated amounts are present due to the inherent imprecision in the ALLL calculation.

Transfers and Servicing of Financial Assets, Servicing of Financial Assets, Policy [Policy Text Block]

Revenue from the origination and sale of loans in the secondary market is recognized upon the transfer of financial assets and 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 Bank and its affiliates; (2) the transferee has the right to pledge or exchange the assets it received and no condition both constrains the transferee from taking advantage of its right to pledge or exchange and provides more than a trivial benefit to the transferor; and (3) the Bank and its affiliates do 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.

Revenue Recognition, Sales of Services [Policy Text Block]

Trust fees, deposit account service charges and other fees are recognized when payment is received for the services (cash basis), which generally occurs at the time the services are provided.

Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block]

In the ordinary course of business, the Bank 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.

Property, Plant and Equipment, Policy [Policy Text Block]

Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. The estimated useful lives and primary method of depreciation for the principal items are as follows:

	Years
Type of Assets	Minimum		Maximum	Depreciation Method
Buildings and leasehold improvements	10	-	30	Straight-line
Furniture and equipment	3	-	10	Straight-line

Charges for maintenance and repairs are expensed as incurred. When assets are retired or disposed of the related cost and accumulated depreciation are removed from the respective accounts and the resulting gain or loss is recorded.

Loans and Leases Receivable, Real Estate Acquired Through Foreclosure, Policy [Policy Text Block]

Other real estate owned acquired in satisfaction of loans is recorded at the lower of cost or fair value less estimated costs of disposal. When a property is acquired, the excess of the recorded investment in the property over its estimated fair value, less estimated costs of disposal, if any, is charged to the allowance for loan losses.

Subsequent declines in the estimated fair value are recorded in a valuation allowance account. Additions to or reductions from valuation allowances, along with net operating results of the property, are included in other operating expenses.

Transfers and Servicing of Financial Assets, Servicing of Financial Assets, Policy [Policy Text Block]

Mortgage servicing rights are recorded at fair value based on assumptions through a third-party valuation service. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the servicing cost per loan, the discount rate, the escrow float rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses.

Bank Owned Life Insurance [Policy Text Block]

Bank-owned life insurance is carried at cash surrender value, net of surrender and other charges, with increases/decreases reflected as income/expense in the consolidated statements of operations.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Compensation expense for share based awards is recorded over the vesting period at the fair value of the award at the time of grant. The exercise price of options or fair value of nonvested shares granted under the Company’s incentive plans is equal to the fair market value of the underlying stock at the grant date. The Company assumes no projected forfeitures on its stock based compensation, since actual historical forfeiture rates on its stock based incentive awards has been negligible.

Income Tax, Policy [Policy Text Block]

The Company files a consolidated federal income tax return. Income tax expense is generally allocated as if the Company and its subsidiaries file separate income tax returns. For state purposes, the Bank files a franchise tax return and the remaining entities file a consolidated income tax return. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

There were no material unrecognized tax benefits or any interest or penalties on any unrecognized tax benefits as of December 31, 2012 and 2011.

Any interest and penalties related to income taxes would be recorded as other operating expense in the consolidated statements of operations.

Treasury Stock [Text Block]

On July 26, 2011, our Board of Directors authorized the implementation of a share repurchase program to repurchase up to $1.0 million of the Company’s outstanding shares of common stock through December 31, 2011. Pursuant to the program, we repurchased 45,039 shares of common stock during the third quarter of 2011 for an aggregate cost of $658,000. On October 18, 2011, our Board of Directors amended the Company’s share repurchase program by increasing the remaining amount of authorized repurchases to $5.0 million, and extending the expiration of the program to December 31, 2012. For the year of 2012 we repurchased a total of 104,518 shares of common stock at a cost of $1.8 million, with $2.4 million remaining in the current share repurchase program at December 31, 2012 .

On January 15, 2013, the Company's board of directors announced the renewal of the Company's share repurchase program, extending the expiration of the program to December 31, 2014 and increasing the remaining amount of authorized repurchases under the program to $5.0 million from the approximately $2.4 million of authorized repurchases that had previously remained. Pursuant to the program, the Company may continue to repurchase shares from time to time in the open market, and the method, timing and amounts of repurchase will be solely in the discretion of the Company's management. The repurchase program does not require the Company to acquire a specific number of shares. Therefore, the amount of shares repurchased pursuant to the program will depend on several factors, including market conditions, capital and liquidity requirements, and alternative uses for cash available.

Comprehensive Income, Policy [Policy Text Block]

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of shareholders’ equity on the consolidated balance sheets, and are disclosed in the consolidated statements of comprehensive income.

The components of accumulated other comprehensive income, included in shareholders’ equity, net of tax, are as follows:

	Year Ended December 31,

Stock Compensation Plans [Abstract]

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]

Stock Compensation Plans

The Company maintains the MidWestOne Financial Group, Inc. 2008 Equity Incentive Plan (the “Plan”) as a means to attract, retain and reward certain designated employees and directors of, and service providers to, the Company and its subsidiaries. Under the terms of the Plan, the Company may grant a total of 750,000 total shares of the Company’s common stock as stock options, stock appreciation rights or stock awards (including restricted stock units) and may also grant cash incentive awards to eligible individuals. As of December 31, 2012 and 2011, 496,614 and 494,389 shares, respectively, of the Company’s common stock remained available for future awards under the Plan.

During 2012, the Company recognized $266,000 of stock based compensation expense, which consisted of $234,000 of expense related to restricted stock unit grants and $32,000 of expense related to stock option grants. In comparison, during 2011, the Company recognized $220,000 of stock based compensation expense, which consisted of $171,000 for restricted stock unit grants and $49,000 for stock option grants, while total stock based compensation expense in 2010 was $190,000 which consisted of $140,000 for restricted stock unit grants and $50,000 for stock option grants.

Incentive Stock Options:

The Company is required to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as compensation expense in the Company’s consolidated statements of operations over the requisite service periods using a straight-line method. Since stock-based compensation expense is based on awards ultimately expected to vest, the expense is reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

The stock options have a maximum term of ten years, an exercise price equal to the fair market value of a share of stock on the date of grant and vest 25% per year over four years, with the first vesting date being the one-year anniversary of the grant date.

The following is a summary of stock option activity for the year ended December 31, 2012:

					Weighted-
					Average
			Weighted-		Remaining	Aggregate
			Average		Contractual	Intrinsic

	Shares		Price		Years	($000)

Exercisable at December 31, 2012	98,576		$	18.36	2.73	248

During 2012, the Company received $590,000 of cash from the exercise of stock option awards and recorded a $38,000 tax benefit from these exercises. Plan participants realized an intrinsic value of $278,000 from the exercise of these stock options during 2012. In comparison, Plan participants realized an intrinsic value of $22,000 and $19,000 from the exercise of stock options during 2011 and 2010, respectively. As of December 31, 2012, the total compensation costs related to nonvested stock options that have not yet been recognized totaled $4,000, and the weighted-average period which these costs are expected to be recognized over is approximately 0.4 years .

There were no stock option awards granted in 2012, 2011, or 2010.

Restricted Stock Units:

Under the Plan, the Company may grant restricted stock unit awards that vest upon the completion of future service requirements or specified performance criteria. The fair value of these awards is equal to the market price of the common stock at the date of the grant. The Company recognizes stock-based compensation expense for these awards over the vesting period, using the straight-line method, based upon the number of awards ultimately expected to vest. Each restricted stock unit entitles the recipient to receive one share of stock on the vesting date. Generally, the restricted stock units vest 25% per year over four years , with the first vesting date being the one-year anniversary of the grant date, or 100% upon the death, disability or retirement of the recipient, or upon change of control (as defined in the Plan) of the Company. If a participant terminates employment prior to the end of the continuous service period, the unearned portion of the stock unit award is forfeited. The Company may also issue awards that vest upon satisfaction of specified performance criteria. For these types of awards, the final measure of compensation cost is based upon the number of shares that ultimately vest considering the performance criteria.

The following is a summary of nonvested restricted stock unit activity for the year ended December 31, 2012:

			Weighted-
			Average
			Grant-Date
	Shares		Fair Value
Nonvested at December 31, 2011	45,690		$	11.38
Granted	22,232		17.81
Vested	(15,810	)	10.98
Forfeited	—		—
Nonvested at December 31, 2012	52,112		$	8.17

The fair value of restricted stock unit awards that vested during 2012 was $324,000, compared to $153,000 and $61,000 during the years ended December 31, 2011 and 2010, respectively. As of December 31, 2012, the total compensation costs related to nonvested restricted stock units that have not yet been recognized totaled $509,000, and the weighted average period over which these costs are expected to be recognized is approximately 2.6 years.

Value Information:

The Company uses the modified Black-Scholes option pricing model (”Black-Scholes model”) for determining the fair value of stock options issued to employees and directors. The determination of the fair value of share-based payment awards using the Black-Scholes model is impacted by the Company’s stock price on the date of grant as well as several assumptions used as inputs into the model. The assumptions include the risk-free interest rate at grant date, expected stock volatility, expected dividend payout, and expected option life.

The risk-free interest rate assumption is based upon observed interest rates for the expected term of the Company’s stock options. The expected volatility input into the model takes into account the historical volatility of the Company’s stock over the period that it has been publicly traded or the expected term of the option. The expected dividend yield assumption is based upon the Company’s historical dividend payout determined at the date of grant, if any.

Fair Value Measurements [Abstract]

Fair Value Disclosures [Text Block]

Estimated Fair Value of Financial Instruments and Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact.

U.S. GAAP requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, U.S. GAAP establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

• Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

• Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

• Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

It is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. Market conditions in recent years have led to diminished, and in some cases, non-existent trading in certain of the financial asset classes. The Company is required to use observable inputs, to the extent available, in the fair value estimation process unless that data results from forced liquidations or distressed sales. Despite the Company’s best efforts to maximize the use of relevant observable inputs, the current market environment has diminished the observability of trades and assumptions that have historically been available. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.

Valuation methods for instruments measured at fair value on a recurring basis

Securities Available for Sale - The Company’s investment securities classified as available for sale include: debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies, debt securities issued by state and political subdivisions, mortgage-backed securities, collateralized mortgage obligations, corporate debt securities, and equity securities. Quoted exchange prices are available for equity securities, which are classified as Level 1. The Company utilizes an independent pricing service to obtain the fair value of debt securities. On a quarterly basis, the Company selects a sample of 30 securities from its primary pricing service and compares them to a secondary independent pricing service to validate value. In addition, the Company periodically reviews the pricing methodology utilized by the primary independent service for reasonableness. Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies and mortgage-backed obligations are priced utilizing industry-standard models that consider various assumptions, including time value, yield curves, volatility factors, prepayment speeds, default rates, loss severity, current market and contractual prices for the underlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace and are classified as Level 2. Municipal securities are valued using a type of matrix, or grid, pricing in which securities are benchmarked against the treasury rate based on credit rating. These model and matrix measurements are classified as Level 2 in the fair value hierarchy. On an annual basis, a group of selected municipal securities are priced by a securities dealer and that price is used to verify the primary independent service’s valuation.

The Company classifies its pooled trust preferred collateralized debt obligations as Level 3. The portfolio consists of six investments in collateralized debt obligations backed by pools of trust preferred securities issued by financial institutions and insurance companies. The Company has determined that the observable market data associated with these assets do not represent orderly transactions and reflect forced liquidations or distressed sales. Based on the lack of observable market data, the Company estimated fair value based on the observable data available and reasonable unobservable market data. The Company estimated fair value based on a discounted cash flow model which used appropriately adjusted discount rates reflecting credit and liquidity risks.

Mortgage Servicing Rights - The Company recognizes the rights to service mortgage loans for others on residential real estate loans internally originated and then sold. Mortgage servicing rights are recorded at fair value based on assumptions through a third-party valuation service. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the servicing cost per loan, the discount rate, the escrow float rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Because many of these inputs are unobservable, the valuations are classified as Level 3.

The following table summarizes assets measured at fair value on a recurring basis as of December 31, 2012 and 2011. There were no liabilities subject to fair value measurement on a recurring basis as of these dates. The assets are segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value:

* Included in mortgage origination and loan servicing fees in the consolidated statements of operations.

Changes in the fair value of available-for-sale securities are included in other comprehensive income to the extent the changes are not considered other than temporary impairments. Other than temporary impairment tests are performed on a quarterly basis and any decline in the fair value of an individual security below its cost that is deemed to be other than temporary results in a write-down that is reflected directly in the Company’s consolidated statements of operations.

Valuation methods for instruments measured at fair value on a nonrecurring basis

Collateral Dependent Impaired Loans - From time to time, a loan is considered impaired and an allowance for credit losses is established. The specific reserves for collateral dependent impaired loans are based on the fair value of the collateral less estimated costs to sell. The fair value of collateral is determined based on appraisals. In some cases, adjustments are made to the appraised values due to various factors, including age of the appraisal, age of comparables included in the appraisal, and known changes in the market and in the collateral. Because many of these inputs are unobservable, the valuations are classified as Level 3.

Other Real Estate Owned (OREO) - Other real estate owned represents property acquired through foreclosures and settlements of loans. Property acquired is carried at the lower of the carrying amount of the loan at the time of acquisition, or the estimated fair value of the property, less disposal costs. The Company considers third party appraisals as well as independent fair value assessments from real estate brokers or persons involved in selling OREO in determining the fair value of particular properties. Accordingly, the valuation of OREO is subject to significant external and internal judgment. The Company also periodically reviews OREO to determine whether the property continues to be carried at the lower of its recorded book value or fair value of the property, less disposal costs. Because many of these inputs are unobservable, the valuations are classified as Level 3.

The following table discloses the Company’s estimated fair value amounts of its financial instruments recorded at fair value on a nonrecurring basis. It is management’s belief that the fair values presented below are reasonable based on the valuation techniques and data available to the Company as of December 31, 2012 and 2011, as more fully described below.

• Cash and cash equivalents, non-interest-bearing demand deposits, federal funds purchased, securities sold under repurchase agreements, and accrued interest are instruments with carrying values that approximate fair value.

• Investment securities available for sale are measured at fair value on a recurring basis. Held to maturity securities are carried at amortized cost. Fair value is based upon quoted prices, if available. If a quoted price is not available, the fair value is obtained from benchmarking the security against similar securities by using a third-party pricing service.

• Loans held for sale are carried at the lower of cost or fair value, with fair value being based on recent observable loan sales. The portfolio has historically consisted primarily of residential real estate loans.

• 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. The Company does record nonrecurring fair value adjustments to loans to reflect (1) partial write-downs and allowances that are based on the observable market price or appraised value of the collateral or (2) the full charge-off of the loan carrying value.

• Loan pool participation carrying values represent the discounted price paid by us to acquire our participation interests in the various loan pool participations purchased, which approximates fair value.

• The fair value of Federal Home Loan Bank stock is estimated at its carrying value and redemption price of $100 per share.

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

• Federal Home Loan Bank borrowings and long-term debt are recorded at historical cost. The fair value of these items is estimated using discounted cash flow analysis, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements.

The following presents the valuation technique(s), observable inputs, and quantitative information about the unobservable inputs used for fair value measurements of the financial instruments held by the Company at December 31, 2012, categorized within Level 3 of the fair value hierarchy:

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

Changes in assumptions or estimation methodologies may have a material effect on these estimated fair values.

There were no held to maturity securities with gross unrealized losses as of December 31, 2011.

The Company’s assessment of other-than-temporary impairment is based on its reasonable judgment of the specific facts and circumstances impacting each individual security at the time such assessments are made. The Company reviews and considers factual information, including expected cash flows, the structure of the security, the credit quality of the underlying assets and the current and anticipated market conditions.

The receipt of principal, at par, and interest on mortgage-backed securities is guaranteed by the respective government-sponsored agency guarantor, such that the Company believes that its mortgage-backed securities do not expose the Company to credit-related losses. The Company's mortgage-backed securities portfolio consisted of securities predominantly underwritten to the standards of and guaranteed by the government-sponsored agencies of FHLMC, FNMA and GNMA.

At December 31, 2012, approximately 63% of the municipal obligations held by the Company were Iowa-based. The Company does not intend to sell these municipal obligations, and it is more likely than not that the Company will not be required to sell them until the recovery of its cost. Due to the issuers’ continued satisfaction of their obligations under the securities in accordance with their contractual terms and the expectation that they will continue to do so, management’s intent and ability to hold these securities for a period of time sufficient to allow for any anticipated recovery in fair value, as well as the evaluation of the fundamentals of the issuers’ financial condition and other objective evidence, the Company believes that the municipal obligations identified in the tables above were temporarily depressed as of December 31, 2012 and 2011.

At December 31, 2012, the Company owned six collateralized debt obligations backed by pools of trust preferred securities with an original cost basis of $9.8 million. The book value of these securities as of this date totaled $1.8 million after other-than-temporary impairment charges during 2008, 2009, and 2010. All of the Company’s trust preferred collateralized debt obligations are in mezzanine tranches and are currently rated less than investment grade by Moody’s Investor Services. They are secured by trust preferred securities of banks and insurance companies throughout the United States, and were rated as investment grade securities when purchased between March 2006 and December 2007. However, as the banking climate eroded during 2008, the securities experienced cash flow problems. Due to continued market deterioration in these securities during 2009 and 2010, additional pre-tax charges to earnings were recorded. No additional charges have been recognized during 2011 or 2012. The market for these securities is considered to be inactive. The Company uses a discounted cash flow model to determine the estimated fair value of its pooled trust preferred collateralized debt obligations and to assess other-than-temporary impairment. The assumptions used in preparing the discounted cash flow model include the following: estimated discount rates (using yields of comparable traded instruments adjusted for illiquidity and other risk factors), estimated deferral and default rates on collateral, and estimated cash flows. The Company also reviewed a stress test of these securities to determine the additional deferrals or defaults in the collateral pool in excess of what the Company believes is probable, before the payments on the individual securities are negatively impacted.

As of December 31, 2012, the Company also owned $1.7 million of equity securities in banks and financial service-related companies. Equity securities are considered to have other-than-temporary impairment whenever they have been in a loss position, compared to current book value, for twelve consecutive months, and the Company does not expect them to recover to their original cost basis. During 2012, no impairment charges were recorded, as the affected equity securities were not deemed impaired due to stabilized market prices in relation to the Company’s original purchase price.

The following table provides a roll forward of credit losses on fixed maturity securities recognized in net income:

	Year Ended December 31,
	2012		2011
(in thousands)
Beginning balance	$	2,802	$	2,802
Additional credit losses:
Securities with no previous other than temporary impairment	—		—
Securities with previous other than temporary impairments	—		—
Ending balance	$	2,802	$	2,802

It is reasonably possible that the fair values of the Company’s investment securities could decline in the future if the overall economy and the financial condition of some of the issuers deteriorate and the liquidity of these securities remains depressed. As a result, there is a risk that additional other-than-temporary impairments may occur in the future and any such amounts could be material to the Company’s consolidated statements of operations.

The contractual maturity distribution of investment debt securities at December 31, 2012, is summarized as follows:

	Available For Sale				Held to Maturity
	Amortized Cost		Fair Value		Amortized Cost		Fair Value
(in thousands)
Due in one year or less	$	19,656	$	19,949	$	525	$	526
Due after one year through five years	92,562		96,312		2,759		2,747
Due after five years through ten years	126,758		132,589		7,179		7,338
Due after ten years	61,962		63,892		12,073		12,055
Mortgage-backed securities and collateralized mortgage obligations	236,713		243,118		10,133		10,254
Total	$	537,651	$	555,860	$	32,669	$	32,920

Mortgage-backed and collateralized mortgage obligations are collateralized by mortgage loans guaranteed by U.S. government agencies. Experience has indicated that principal payments will be collected sooner than scheduled because of prepayments. Therefore, these securities are not scheduled in the maturity categories indicated above. Other equity securities available for sale with an amortized cost of $1.6 million and a fair value of $1.7 million are also excluded from this table.

Proceeds from the sales of investment securities available for sale during 2012 were $18.3 million. During 2011 there were no sales of investment securities available for sale, as realized gains during 2011 were the result of the accelerated maturity of certain debt securities possessing a call feature, while in 2010 sale proceeds were $16.9 million.

Other investment securities include investments in Federal Home Loan Bank (“FHLB”) stock. The carrying value of the FHLB stock at December 31, 2012 and December 31, 2011 was $11.1 million and $12.2 million, respectively, which is included in the Other Assets line of the consolidated balance sheets. This security is not readily marketable and ownership of FHLB stock is a requirement for membership in the FHLB Des Moines. The amount of FHLB stock the Bank is required to hold is directly related to the amount of FHLB advances borrowed. Because there are no available market values for this security, it is carried at cost and evaluated for potential impairment each quarter. Redemption of this investment is at the option of the FHLB.

Realized gains and losses on sales are determined on the basis of specific identification of investments based on the trade date. Realized gains (losses) on investments, including impairment losses for the years ended December 31, 2012, 2011 and 2010, were as follows:

Variable Interest Entities [Abstract]

Variable Interest Entity [Text Block]

Variable Interest Entities

MidWestOne has invested in certain participation certificates of loan pools which are purchased, held and serviced by the third-party independent servicing corporation. MidWestOne’s portfolio holds approximately 95% of participation interests in pools of loans owned and serviced by States Resources Corporation (“SRC”), a third-party loan servicing organization in Omaha, Nebraska. SRC’s owner holds the rest. The Company does not have any ownership interest in or exert any control over SRC, and thus it is not included in the consolidated financial statements.

These pools of loans were purchased from large nonaffiliated banking organizations and from the FDIC acting as receiver of failed banks and savings associations. As loan pools were put out for bid (generally in a sealed bid auction) SRC’s due diligence teams evaluated the loans and determined their interest in bidding on the pool. After the due diligence, MidWestOne management reviewed this information and decided if it wished to continue in the process. If the decision to consider a bid was made, SRC conducted additional analysis to determine the appropriate bid price. This analysis involved discounting loan cash flows with adjustments made for expected losses and changes in collateral values as well as targeted rates of return. A cost or investment basis was assigned to each individual loan at cents per dollar (discounted price) based on SRC’s assessment of the recovery potential of each loan.

Once a bid was awarded to SRC, the Company assumed the risk of profit or loss but on a non-recourse basis so the risk is limited to its initial investment. The extent of the risk is also dependent upon: the debtor or guarantor’s financial condition, the possibility that a debtor or guarantor may file for bankruptcy protection, SRC’s ability to locate any collateral and obtain possession, the value of such collateral, and the length of time it takes to realize the recovery either through collection procedures, legal process, or resale of the loans after a restructure.

Loan pool participations are shown on the Company’s consolidated balance sheets as a separate asset category. The original carrying value or investment basis of loan pool participations is the discounted price paid by the Company to acquire its interests, which, as noted, is less than the face amount of the underlying loans. MidWestOne’s investment basis is reduced as SRC recovers principal on the loans and remits its share to the Company or as loan balances are written off as uncollectible.

Employee Benefit Plans [Abstract]

Compensation and Employee Benefit Plans [Text Block]

Employee Benefit Plans

Prior to the Company’s merger with the Former MidWestOne, the Bank sponsored a noncontributory defined benefit pension plan for substantially all its employees. Effective December 31, 2007, the Bank elected to curtail the plan by limiting this employee benefit to those employees vested as of December 31, 2007. During the second quarter of 2012, the Company completed the liquidation of plan assets and full termination of the plan, including full benefit payout to plan participants. The total amount of the Company’s required contribution to fully fund the plan for liquidation was $6.1 million, pre-tax, which is included in Salaries and Employee Benefits expense on the consolidated statements of operations.

The Company has a salary reduction profit-sharing 401(k) plan covering all employees fulfilling minimum age and service requirements. Employee contributions to the plan are optional. Employer contributions are discretionary and may be made to the plan in an amount equal to a percentage of each participating employee’s salary. The 401(k) contribution expense for this plan totaled $667,000, $629,000 and $614,000 for the years ended December 31, 2012, 2011 and 2010, respectively.

The Company has an employee stock ownership plan (ESOP) covering all employees fulfilling minimum age and service requirements. Employer contributions are discretionary and may be made to the plan in an amount equal to a percentage of each participating employee’s salary. The ESOP contribution expense for this plan totaled $635,000, $534,000 and $266,000 for the years ended December 31, 2012, 2011 and 2010, respectively.

The Company has a salary continuation plan for several officers and directors. These plans provide annual payments of various amounts upon retirement or death. The Company accrues the expense for these benefits by charges to operating expense during the period the respective officer or director attains full eligibility. The amount charged to operating expense during the years ended December 31, 2012, 2011 and 2010 totaled $359,000, $372,000 and $320,000, respectively. To provide the retirement benefits, the Company carries life insurance policies with cash values totaling $13.5 million, $13.0 million and $12.6 million at December 31, 2012, 2011 and 2010, respectively
