Notes to Consolidated Financial Statements

(Unaudited)

1.    Principles of Consolidation and Presentation

MidWestOne Financial Group, Inc. (the “Company,” which is also referred to herein as “we,” “our” or “us”) is an Iowa corporation incorporated in 1983, a bank holding company under the Bank Holding Company Act of 1956 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 May 1, 2015, the Company completed its merger with Central Bancshares, Inc. ("Central"), pursuant to which Central was merged with and into the Company. In connection with the merger, Central Bank, a Minnesota-chartered commercial bank and wholly-owned subsidiary of Central, became a wholly-owned subsidiary of the Company.

The Company issued 2,723,083 shares of common stock and paid $64.0 million in cash, for total consideration of $136.6 million in connection with the merger. The results of operations acquired from Central have been included in the Company's results of operations for the 60 days since the date of acquisition.

The Company owns 100% of the outstanding common stock of MidWestOne Bank, an Iowa state non-member bank chartered in 1934 with its main office in Iowa City, Iowa, 100% of the common stock of Central Bank, a Minnesota state non-member bank chartered in 1988 with its main office in Golden Valley, Minnesota, and 100% of the common stock of MidWestOne Insurance Services, Inc., Oskaloosa, Iowa. We operate primarily through our bank subsidiaries, MidWestOne Bank and Central Bank, and MidWestOne Insurance Services, Inc., our wholly-owned subsidiary that operates an insurance agency business through six offices located in central and east-central Iowa.

The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all the information and notes necessary for complete financial statements in conformity with U.S. Generally Accepted Accounting Principles ("GAAP"). The information in this Quarterly Report on Form 10-Q is written with the presumption that the users of the interim financial statements have read or have access to the most recent Annual Report on Form 10-K of the Company, which contains the latest audited financial statements and notes thereto, together with Management's Discussion and Analysis of Financial Condition and Results of Operations as of December 31, 2014 and for the year then ended. Management believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, the accompanying consolidated financial statements contain all adjustments (consisting of only normal recurring accruals) necessary to present fairly the Company's financial position as of June 30, 2015, and the results of operations and cash flows for the three and six months ended June 30, 2015 and 2014. All significant intercompany accounts and transactions have been eliminated in consolidation.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect: (1) the reported amounts of assets and liabilities, (2) the disclosure of contingent assets and liabilities at the date of the financial statements, and (3) the reported amounts of revenues and expenses during the reporting period. These estimates are based on information available to management at the time the estimates are made. Actual results could differ from those estimates. The results for the three and six months ended June 30, 2015 may not be indicative of results for the year ending December 31, 2015, or for any other period.

All significant accounting policies followed in the preparation of the quarterly financial statements are disclosed in the Annual Report on Form 10-K for the year ended December 31, 2014. In the consolidated statements of cash flows, cash and cash equivalents include cash and due from banks and interest-bearing deposits in banks.

Certain reclassifications have been made to prior periods' consolidated financial statements to present them on a basis comparable with the current period's consolidated financial statements.

2.    Business Combination

On May 1, 2015, the Company acquired 100% of the voting equity interests of Central, a bank holding company and the parent company of Central Bank, a commercial bank headquartered in Golden Valley, Minnesota, through the merger of Central with and into the Company. Among other things, this transaction provides the Company with the opportunity to expand the business into new markets and grow the size of the business. At the effective time of the merger, each share of common stock of Central converted into a pro rata portion of (1) 2,723,083 shares of common stock of the Company, and (2) $64.0 million in cash.

7

This business combination was accounted for under the acquisition method of accounting. Accordingly, the results of operations of the acquired company have been included in the Company’s results of operations since the date of acquisition. Under this method of accounting, assets and liabilities acquired are recorded at their estimated fair values. The excess cost over fair value of net assets acquired is recorded as goodwill. As the consideration paid for Central exceeded the net assets acquired, goodwill of $56.5 million was recorded on the acquisition. Goodwill recorded in this transaction, which reflect the entry into the geographically new markets served by Central, has been provisionally allocated to our Central Bank segment. Goodwill recorded in the transaction is not tax deductible. The fair value of certain assets and liabilities and results recognized in the financial statements for the business combination have been determined only provisionally as of the second quarter of 2015. The following acquired assets and liabilities are included within the consolidated financial statements as of June 30, 2015 as provisional amounts as the Company continues to gather information to estimate the fair value as of the date of acquisition: 1) trade name intangible valuation is being reviewed to determine the appropriate valuation methodology and royalty rate; 2) FDIC indemnification asset continues to be reviewed and adjustments made relating to claimable expenses, losses, and recoveries; 3) other real estate owned includes a significant property for which a new appraisal has not been performed due to its pending sale; 4) deferred taxes remain provisional as the Company continues the process of transitioning Central Bank from an S-Corp to a C-Corp; 5) stock illiquidity discount continues to be reviewed to determine the length of the restriction and the impact of this restriction on the fair value of the stock issued as part of the consideration. The Company expects to obtain the additional information needed to finalize these amounts in the third quarter of 2015.

Estimated fair values of assets acquired and liabilities assumed in the Central transaction, as of the closing date of the transaction, were as follows:

Purchased loans acquired in a business combination are recorded and initially measured at their estimated fair value as of the acquisition date. Credit discounts are included in the determination of fair value. An allowance for loan losses is not carried over. These purchased loans are segregated into two types: purchased credit impaired loans and purchased non-credit impaired loans without evidence of significant credit deterioration.

8

• Purchased credit impaired loans are accounted for in accordance with ASC 310-30 "Loans and Debt Securities Acquired with Deteriorated Credit Quality" as they display significant credit deterioration since origination and it is probable, as of the acquisition date, that the Company will be unable to collect all contractually required payments from the borrower.

• Purchased non-credit impaired loans are accounted for in accordance with ASC 310-20 “Nonrefundable Fees and Other Costs” as these loans do not have evidence of significant credit deterioration since origination and it is probable all contractually required payments will be received from the borrower.

For purchased non-credit impaired loans, the difference between the estimated fair value of the loans (computed on a loan-by-loan basis) and the principal outstanding is accreted over the remaining life of the loans.

For purchased credit impaired loans the difference between contractually required payments at acquisition and the cash flows expected to be collected is referred to as the non-accretable difference. Further, any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the expected remaining life of the loan if the timing and amount of the future cash flows are reasonably estimable. Subsequent to the purchase date, increases in cash flows over those expected at the purchase date are recognized as interest income prospectively. The present value of any decreases in expected cash flows after the purchase date is recognized by recording an allowance for credit losses and a provision for loan losses.

The following table presents the purchased loans as of the acquisition date:

(in thousands)	Purchased Credit Impaired Loans			Purchased Non-Credit Impaired Loans
Contractually required principal payments	$	36,886		$	905,314
Nonaccretable difference	(6,675		)	—
Principal cash flows expected to be collected	30,211			905,314
Accretable difference	(1,882		)	(16,670		)
Fair value of acquired loans	$	28,329		$	888,644

Disclosures required by FAS ASC 805-20-50-1(a) concerning the FDIC indemnification assets have not been included due to the immateriality of the amount involved. See Note 6. "Loans Receivable and the Allowance for Loan Losses" to our consolidated financial statements for additional information related to the FDIC indemnification asset.

FAS ASC 805-30-30-7 requires that the consideration transfered in a business combination should be measured at fair value. Since the common shares issued as part of the consideration of the merger included a restriction on their sale, pledge or other disposition, an illiquidity discount has been assigned to the shares based upon the volatility of the underlying shares' daily returns and the period of restriction.

The Company recorded $2.7 million and $3.2 million in pre-tax merger-related expenses for the three and six months ended 2015, respectively, including professional and legal fees of $1.5 million and $1.7 million, respectively, to directly consummate the merger. These amounts are included in professional fees in the Company's consolidated statements of operations. The remainder of merger-related expenses primarily relate to retention and severance compensation costs, which are included in salaries and employee benefits in the consolidated statements of operations, and service contract termination costs, which are included in other operating expenses.

The following table provides the unaudited pro forma information for the results of operations for the three and six months ended June 30, 2015 and 2014, as if the acquisition had occurred January 1, 2014. The pro forma results combine the historical results of Central into the Company’s consolidated statement of income including the impact of certain purchase accounting adjustments, including loan discount accretion, investment securities discount accretion, intangible assets amortization, deposit premium accretion and borrowing discount amortization. The pro forma results have been prepared for comparative purposes only and are not necessarily indicative of the results that would have been obtained had the acquisition actually occurred on January 1, 2014. No assumptions have been applied to the pro forma results of operations regarding possible revenue enhancements, expense efficiencies or asset dispositions. The merger-related expenses that have been recognized are included in net income in the table below.

	Pro Forma
	Three Months Ended		Six Months Ended
	June 30,		June 30,
(in thousands)	2015	2014	2015	2014
Total revenues (net interest income plus noninterest income)	31,634	32,551	65,078	64,924
Net income	5,236	4,694	12,875	10,797

The pro forma information above excludes the impact of any provision recorded related to renewing Central loans. Revenues and earnings included in the consolidated statements of operations of the acquired company since the acquisition date for both the three and six months ended June 30, 2015 were $10.5 million and $2.1 million, respectively.

3.    Shareholders' Equity

Preferred Stock: The number of authorized shares of preferred stock for the Company is 500,000. As of June 30, 2015, none were issued or outstanding.

Common Stock: As of June 30, 2015, the number of authorized shares of common stock for the Company was 15,000,000. As of June 30, 2015, 11,405,931 shares were outstanding.

On May 1, 2015, in connection with the Central merger, the Company issued 2,723,083 shares of its common stock. On June 22, 2015, the Company entered into a Securities Purchase Agreement with certain institutional accredited investors, pursuant to which, on June 23, 2015, the Company sold an aggregate of 300,000 newly issued shares of the Company’s common stock, $1.00 par value per share, at a purchase price of $28.00 per share. Each of the purchasers was an existing shareholder of the Company.

On July 17, 2014, the board of directors of the Company approved a new share repurchase program, allowing for the repurchase of up to $5.0 million of stock through December 31, 2016. The new repurchase program replaced the Company's prior repurchase program, pursuant to which the Company had repurchased approximately $3.7 million of common stock since January 1, 2013. Pursuant to the new 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. During the second quarter of 2015 the Company repurchased no common stock. Of the $5.0 million of stock authorized under the repurchase plan, $3.8 million remained available for possible future repurchases as of June 30, 2015.

4.    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.

Investment securities with a carrying value of $314.5 million and $200.7 million at June 30, 2015 and December 31, 2014, respectively, were pledged on public deposits, securities sold under agreements to repurchase and for other purposes, as required or permitted by law.

The summary of investment securities shows that some of the securities in the available for sale and held to maturity investment portfolios had unrealized losses, or were temporarily impaired, as of June 30, 2015 and December 31, 2014. This temporary impairment represents the estimated amount of loss that would be realized if the securities were sold on the valuation date. 

The following presents information pertaining to securities with gross unrealized losses as of June 30, 2015 and December 31, 2014, aggregated by investment category and length of time that individual securities have been in a continuous loss position:

The Company's assessment of other-than-temporary impairment ("OTTI") 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 creditworthiness of the issuer, the type of underlying assets, if any, and the current and anticipated market conditions. 

At June 30, 2015 and December 31, 2014, the Company's mortgage-backed securities and collateralized mortgage obligations portfolios consisted of securities predominantly backed by one- to four-family mortgage loans and underwritten to the standards of and guaranteed by the following government-sponsored agencies: the Federal Home Loan Mortgage Corporation ("FHLMC"), the Federal National Mortgage Association ("FNMA"), and the Government National Mortgage Association ("GNMA"). 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.

At June 30, 2015, approximately 58% of the municipal bonds held by the Company were Iowa-based, and approximately 20% were Minnesota-based. The Company does not intend to sell these municipal obligations, and it is not more likely than not that the Company will be required to sell them before the recovery of their cost. Due to the issuers' continued satisfaction of their obligations under the securities in accordance with their contractual terms and the expectation that they will continue to do so, management's intent and ability to hold these securities for a period of time sufficient to allow for any anticipated recovery at fair value, as well as the evaluation of the fundamentals of the issuers' financial conditions and other objective evidence, the Company believes that the municipal obligations identified in the tables above were temporarily impaired as of June 30, 2015 and December 31, 2014.

As of June 30, 2015, the Company also owned $0.3 million of equity securities in banks and financial service-related companies, and $1.0 million of mutual funds invested in debt securities and other debt instruments that will cause units of the fund to be deemed to be qualified under the Community Reinvestment Act. Equity securities are considered to

13

have OTTI 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. For the six months ended June 30, 2015 and the full year of 2014, 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:

	For the Six Months Ended June 30,
	2015		2014
(in thousands)
Beginning balance	$	—	$	6,639
Additional credit losses:
Reductions to credit losses:
Securities with other than temporary impairment, due to liquidation	—		—
Securities with other than temporary impairment, due to sale	—		(6,639		)
Ending balance	$	—	$	—

It is reasonably possible that the fair values of the Company's investment securities could decline in the future if the overall economy or the financial conditions of the issuers deteriorate. As a result, there is a risk that additional OTTI may be recognized 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 June 30, 2015, 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	$	33,880	$	34,346	$	190	$	190
Due after one year through five years	80,530		82,256		5,558		5,540
Due after five years through ten years	101,917		105,549		40,648		40,043
Due after ten years	28,681		28,946		22,561		22,072
Debt securities without a single maturity date	178,343		177,520		29,792		29,230
Total	$	423,351	$	428,617	$	98,749	$	97,075

Mortgage-backed securities and collateralized mortgage obligations are collateralized by mortgage loans and guaranteed by U.S. government agencies. Our 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. Equity securities available for sale with an amortized cost of $1.2 million and a fair value of $1.3 million are also excluded from this table.

Other investment securities include investments in Federal Home Loan Bank (“FHLB”) stock. The carrying value of the FHLB stock at June 30, 2015 was $10.4 million and at December 31, 2014 was $8.6 million, 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 held is directly related to the amount of FHLB advances borrowed. Because 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.

Realized gains and losses on sales are determined on the basis of specific identification of investments based on the trade date. Realized gains on investments for the three and six months ended June 30, 2015 and 2014 are as follows:

Loan Portfolio Segment Risk Characteristics

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

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

16

these loans.

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

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

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

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 a partial or full charge-off, a request for approval of a charge-off is submitted to the bank's President, Executive Vice President and Chief Credit Officer, and the Senior Regional Loan officer. The bank's board of directors formally approves all loan charge-offs. Once a loan is charged-off, it cannot be restructured and returned to the bank's books.

The Allowance for Loan and Lease Losses

The Company requires the maintenance of an adequate allowance for loan and lease losses (“ALLL”) in order to cover estimated probable losses without eroding the Company's capital base. Calculations are done at each quarter end, or more frequently if warranted, to analyze the collectability of loans and to ensure the adequacy of the allowance. In line with Federal Deposit Insurance Corporation (the "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 due to those overall factors impacting the ALLL that are not captured in detailed loan category calculations.

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

17

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

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

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

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

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

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

• The borrower receives a reduction of the accrued interest.

Loans Reviewed Collectively for Impairment

All loans not evaluated individually for impairment 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 and over 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

18

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 banks' existing portfolios.

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 greater risk than special mention loans, and as such, this subset is reserved at six times the pass allocation. Further, non-impaired loans less than $0.2 million that are past due 60 - 89 days or 90 days and over, are respectively classified as special mention or substandard. They are given an increased loan loss allocation of 25% or 50%, respectively, above the five-year historical loss rate of the specific loan type.

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

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

Doubtful - Loans classified 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 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, and certain loans rated substandard, 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 with marketable collateral and is in the process of collection. An established track record of performance is also considered when determining accrual status.

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

23

days and 60-89 days columns in the table above reflect contractual delinquency status of loans not considered nonperforming due to classification as a TDR or being placed on non-accrual.

The following table sets forth the composition of the Company's recorded investment in loans on nonaccrual status and past due ninety days or more and still accruing by class of loans, excluding purchased credit impaired loans, as of June 30, 2015 and December 31, 2014:

Not included in the loans above as of June 30, 2015, were purchased credit impaired loans with an outstanding balance of $5.5 million, net of a discount of $1.9 million.

As of June 30, 2015, the Company had no commitments to lend additional funds to any borrowers who have had a TDR.

Purchased Loans

Purchased loans acquired in a business combination are recorded and initially measured at their estimated fair value as of the acquisition date. Credit discounts are included in the determination of fair value. An allowance for loan losses is not carried over. These purchased loans are segregated into two types: purchased credit impaired loans and purchased non-credit impaired loans.

• Purchased credit impaired loans are accounted for in accordance with ASC 310-30 "Loans and Debt Securities Acquired with Deteriorated Credit Quality" as they display significant credit deterioration since origination and it is probable, as of the acquisition date, that the Company will be unable to collect all contractually required payments from the borrower.

• Purchased non-credit impaired loans are accounted for in accordance with ASC 310-20 “Nonrefundable Fees and Other Costs” as these loans do not have evidence of significant credit deterioration since origination and it is probable all contractually required payments will be received from the borrower.

For purchased non-credit impaired loans the accretable discount is the discount applied to the expected cash flows of the portfolio to account for the differences between the interest rates at acquisition and rates currently expected on similar portfolios in the marketplace. As the accretable discount is accreted to interest income over the expected average life of the portfolio, the result will be interest income on loans at the estimated current market rate. We anticipate recording a provision for the acquired portfolio in future quarters as the Central loans renew and the discount is accreted.

For purchased credit impaired loans the difference between contractually required payments at acquisition and the cash flows expected to be collected is referred to as the non-accretable difference. Further, any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the expected remaining life of the loan if the timing and amount of the future cash flows are reasonably estimable.

24

This discount includes an adjustment on loans that are not accruing or paying contractual interest so that interest income will be recognized at the estimated current market rate.

Subsequent to the purchase date, increases in cash flows over those expected at the purchase date are recognized as interest income prospectively. The present value of any decreases in expected cash flows after the purchase date is recognized by recording an allowance for credit losses and a provision for loan losses.

Changes in the accretable yield for loans acquired and accounted for under ASC 310-30 were as follows for the three and six months ended June 30, 2015 and 2014:

	Three Months Ended June 30,			Six Months Ended June 30,

Balance at end of period	1,839		—	1,839		—

Loan Pool Participations

The Company acquired its loan pool participations in a prior merger and continued in this business following that merger. However, in 2010, the Company made the decision to exit this line of business and did not purchase new loan pool participations as existing pools paid down. The Company sold its remaining loan pool participations in June 2015, and has now completely exited this line of business.

7.    Goodwill and Intangible Assets

The excess of the cost of an acquisition over the fair value of the net assets acquired, including core deposit, trade name, and client relationship intangibles, consists of goodwill. Under ASC Topic 350, goodwill is subject to at least annual assessments for impairment by applying a fair value based test. The Company reviews goodwill to determine potential impairment annually, or more frequently if events and circumstances indicate that goodwill might be impaired, by comparing the carrying value of the reporting unit with the fair value of the reporting unit.

The Company's annual assessment date is as of October 1. Goodwill is tested for impairment at the reporting unit level. The Company has two reporting units: MidWestOne Bank and Central Bank. No impairment losses were recognized during the three and six months ended June 30, 2015. The carrying amount of goodwill was $56.5 million at June 30, 2015 and zero at December 31, 2014. The increase of $56.5 million in goodwill was due to the Central merger.

The Company recognized a $56.5 million goodwill intangible, a $12.8 million core deposit intangible, and a $2.8 million trade name intangible in the second quarter of 2015 due to the Central merger.

The following table presents the changes in the carrying amount of intangibles (excluding goodwill), gross carrying amount, accumulated amortization, and net book value as of June 30, 2015:

	Insurance Agency Intangible			Core Deposit Intangible			Trade Names Intangible			Customer List Intangible			Total

8.    Other Assets

The components of the Company's other assets were as follows:

	June 30, 2015		December 31, 2014
(in thousands)
Federal Home Loan Bank Stock	$	10,441	$	8,582
FDIC indemnification asset, net	5,147		—
Prepaid expenses	2,218		1,350
Mortgage servicing rights	2,217		2,308
Accounts receivable & other miscellaneous assets	7,100		1,835
	$	27,123	$	14,075

MidWestOne Bank and Central Bank are each members 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 banks are 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.

As part of the Central merger, the Company became a party to certain loss-share agreements with the FDIC from previous Central-related acquisitions. These agreements cover realized losses on loans and foreclosed real estate for specified periods. These loss-share assets are measured separately from the loan portfolios because they are not contractually embedded in the loans and are not transferable with the loans should the Company choose to dispose of them. Fair values at the acquisition dates were estimated based on projected cash flows available for loss-share based on the credit adjustments estimated for each loan. The loss-share assets are separately measured from the related loans and foreclosed real estate and recorded within other assets on the balance sheet.

Mortgage servicing rights are recorded at fair value based on assumptions provided by 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.

9.    Short-term Borrowings

Short-term borrowings were as follows as of June 30, 2015 and December 31, 2014:

	June 30, 2015				December 31, 2014
(in thousands)	Weighted Average Cost		Balance		Weighted Average Cost		Balance
Federal Reserve Bank advances	—	%	$	—	—	%	$	—
Federal funds purchased	0.29	%	24,700		—	%	—
Securities sold under agreements to repurchase	0.30	%	67,114		0.21	%	60,821
Line of credit	—	%	—		—	%	—
Total	0.30	%	91,814		0.21	%	$	60,821

The Company had a borrowing capacity through the Federal Reserve Discount Window of $11.6 million and $11.8 million as of June 30, 2015 and December 31, 2014, respectively, and municipal securities pledged with a market value of $12.9 million and $13.1 million, respectively, to secure potential borrowings.The Company also has various other unsecured Federal Funds agreements with correspondent banks.

Securities sold under agreements to repurchase are agreements in which the Company acquires funds by selling assets to another party under a simultaneous agreement to repurchase the same assets at a specified price and date. The Company enters into repurchase agreements and also offers a demand deposit account product to customers that sweeps their balances in excess of an agreed upon target amount into overnight repurchase agreements. All securities sold under agreements to repurchase are recorded on the face of the balance sheet.

On April 30, 2015, the Company entered into a $5.0 million unsecured line of credit with a correspondent bank. Interest is payable at a rate of one-month LIBOR + 2.00%. The line is scheduled to mature on April 28, 2016.

26

10.    Subordinated Notes Payable

The Company has established three statutory business trusts, Central Bancshares Capital Trust II, Barron Investment Capital Trust I, and MidWestOne Statutory Trust II, under the laws of the state of Delaware, which exist for the exclusive purposes of (i) issuing trust securities representing undivided beneficial interests in the assets of the trust; (ii) investing the gross proceeds of the trust securities in junior subordinated deferrable interest debentures (subordinated debentures); and (iii) engaging in only those activities necessary or incidental thereto. For regulatory capital purposes, these trust securities qualify as a component of Tier 1 capital.

The table below summarizes the outstanding junior subordinated notes and the related trust preferred securities issued by each trust as of June 30, 2015:

	Face Value		Book Value		Interest Rate	Interest Rate at		Maturity Date	Callable Date
(in thousands)						6/30/2015
Central Bancshares Capital Trust II(1) (2)	$	7,217	$	6,514	Three-month LIBOR + 3.50%	3.78	%	03/15/2038	03/15/2013
Barron Investment Capital Trust I(1) (2)	2,062		1,545		Three-month LIBOR + 2.15%	2.43	%	09/30/2036	09/23/2011
MidWestOne Statutory Trust II(1)	15,464		15,464		Three-month LIBOR + 1.59%	1.87	%	12/15/2037	12/15/2012
Total	$	24,743	$	23,523

(1) All distributions are cumulative and paid in cash quarterly.

(2) Central Bancshares Capital Trust II and Barron Investment Capital Trust I were established by Central prior to the Company's merger with Central, and the junior subordinated notes issued by Central were assumed by the Company.

The trust preferred securities are subject to mandatory redemption, in whole or in part, upon repayment of the junior subordinated notes at the stated maturity date or upon redemption of the junior subordinated notes. Each trust’s ability to pay amounts due on the trust preferred securities is solely dependent upon the Company making payment on the related junior subordinated notes. The Company’s obligation under the junior subordinated notes and other relevant trust agreements, in aggregate, constitutes a full and unconditional guarantee by the Company of each trust’s obligations under the trust preferred securities issued by each trust. The Company has the right to defer payment of interest on the notes and, therefore, distributions on the trust preferred securities, for up to five years, but not beyond the stated maturity date in the table above. During any such deferral period the Company may not pay cash dividends on its stock and generally may not repurchase its stock.

The Company assumed a subordinated note held by 1907 EJF Fund, LTD, which was issued by Central prior to the Company's merger, in the amount of $12.3 million. On June 23, 2015 the Company redeemed the subordinated note.

11.    Long-term Borrowings

Long-term borrowings were as follows as of June 30, 2015 and December 31, 2014:

	June 30, 2015				December 31, 2014
(in thousands)	Weighted Average Cost		Balance		Weighted Average Cost		Balance
FHLB Borrowings	1.74	%	$	78,000	1.88	%	$	93,000
Note payable to unaffiliated bank	2.19	%	25,000		—	%	—
Total	1.85	%	$	103,000	1.88	%	$	93,000

The Company utilizes FHLB borrowings as a supplement to customer deposits to fund earning assets and to assist in managing interest rate risk. The Company has loans pledged as collateral for FHLB borrowings. See Note 6 "Loans Receivable and the Allowance for Loan Losses" of the notes to the consolidated financial statements.

On April 30, 2015, the Company entered into a $35.0 million unsecured note payable with a correspondent bank with a maturity date of June 30, 2020. Payments of principal and interest are payable quarterly beginning July 1, 2015. As of June 30, 2015, $25.0 million of that note was outstanding.

12.    Income Taxes

Federal income tax expense for the three and six months ended June 30, 2015 and 2014 was computed using the consolidated effective federal tax rate. The Company also recognized income tax expense pertaining to state franchise and income taxes payable by the subsidiary banks.

27

13.    Fair Value Measurements

Fair value is the price that would be received in selling an asset or paid in transferring 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 (1) independent, (2) knowledgeable, (3) able to transact and (4) willing to transact.

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, 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 for identical assets or liabilities in active markets 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. 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. 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 agencies and corporations, 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 agencies and corporations 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.

The following table presents the amount of gains and losses on Level 3 assets noted above which were included in earnings and other comprehensive income for the six months ended June 30, 2015 and 2014 that are attributable to the change in unrealized gains and losses relating to those assets still held, and the line item in the consolidated financial statements in which they are included:

Total gains for the period in earnings*	$	—	$	782
Change in unrealized gains for the period included in other comprehensive income	—		794

* Gains on collateralized debt obligations are included in gain on sale or call of available for sale securities 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 OTTI. OTTI 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") - OREO represents property acquired through foreclosures and settlements of loans. Property acquired through or in lieu of foreclosure are initially recorded at fair value less estimated selling cost at the date of foreclosure, establishing a new cost basis. 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 presents the carrying amount and estimated fair value of the financial instruments held by the Company at June 30, 2015 and December 31, 2014. The information presented is subject to change over time based on a variety of factors. The operations of the Company are managed on 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 capitalization and franchise value of MidWestOne Bank and Central Bank. Neither of these components has been given consideration in the presentation of fair values below.

• Cash and cash equivalents, 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 FHLB 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.

32

• FHLB borrowings, Junior subordinated notes issued to capital trusts, subordinated notes, 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 June 30, 2015, categorized within Level 3 of the fair value hierarchy:

	Quantitative Information About Level 3 Fair Value Measurements
(dollars in thousands)	Fair Value at June 30, 2015		Valuation Techniques(s)	Unobservable Input	Range of Inputs		Weighted Average
Collateral dependent impaired loans:	$	7,713	Modified appraised value	Third party appraisal	NM *	NM *	NM *
				Appraisal discount	NM *	NM *	NM *
Other real estate owned	8,894		Modified appraised value	Third party appraisal	NM *	NM *	NM *
				Appraisal discount	NM *	NM *	NM *

* 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, thus providing a range would not be meaningful.

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

14.    Variable Interest Entities

Loan Pool Participations

The Company had invested in certain participation certificates of loan pools which were purchased, held and serviced by a third-party independent servicing corporation. The Company's portfolio held approximately 95% of the participation interests in the pools of loans owned and serviced by States Resources Corporation (“SRC”), a third-party loan servicing organization located in Omaha, Nebraska, in which the Company participated. SRC's owner held the remaining interest. The Company did not have any ownership interest in or exert any control over SRC, and thus it was 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, the Company's management reviewed the status 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, changes in collateral values as well as targeted rates of return. A cost or investment basis was assigned to each individual loan on a cents-per-dollar (discounted price) basis 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 was limited to its initial investment. The extent of the risk was 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 took to realize the recovery either through collection procedures, legal process, or resale of the loans after a restructure.

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

15.    Operating Segments

Selected financial and descriptive information is required to be disclosed for reportable operating segments, applying a “management perspective” as the basis for identifying reportable segments. The management perspective is determined by the view that management takes of the segments within the Company when making operating decisions, allocating resources, and measuring performance. The segments of the Company have been defined by the structure of the Company’s internal organization, focusing on the financial information that the Company’s operating decision-makers routinely use to make decisions about operating matters.

The Company’s primary segment, Commercial Banking, is geographically divided by markets into the secondary segments which are the two subsidiary banks wholly-owned by the Company: MidWestOne Bank and Central Bank (which was acquired May 1, 2015). Each of these secondary segments offers similar products and services, but are managed separately due to different pricing, product demand, and consumer markets. Each offers commercial, consumer, and mortgage loans and deposit services.

The Company’s All Other segment includes the operations of all other consolidated subsidiaries and/or defined operating segments that fall below the segment reporting thresholds. This segment includes the corporate operations of the parent company.

The accounting policies of the segments are generally the same as those of the consolidated company.

16.    Effect of New Financial Accounting Standards

In January 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update No. 2014-01, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. The objective of this update is to provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit. The low-income housing tax credit program is designed to encourage private capital investment in the construction and rehabilitation of low-income housing. This program is an indirect tax subsidy that allows investors in a flow-through limited liability entity, such as limited partnerships or limited liability companies that manage or invest

35

in qualified affordable housing projects, to receive the benefits of the tax credits allocated to the entity that owns the qualified affordable housing project. The tax credits are allowable on the tax return each year over a 10-year period as a result of a sufficient number of units being rented to qualifying tenants and are subject to restrictions on gross rentals paid by those tenants. Those credits are subject to recapture over a 15-year period starting with the first year tax credits are earned. The amendments in this update permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. For public entities, the amendments are to be applied retrospectively to all annual periods and interim reporting periods presented within those annual periods, beginning after December 15, 2014. The adoption of this amendment did not have a material effect on the Company’s consolidated financial statements.

In January 2014, the FASB issued Accounting Standards Update No. 2014-04, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The objective of this update is to reduce diversity by clarifying when an in-substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. For public entities, the amendments are effective for reporting periods beginning after December 31, 2014, with early adoption permitted. The adoption of this amendment did not have a material effect on the Company’s consolidated financial statements.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contract with Customers (Topic 606). The guidance in this update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (for example, insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following five steps: 1) identify the contracts(s) with the customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations in the contract; and 5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also specifies the accounting for some costs to obtain or fulfill a contract with a customer. For a public entity, the amendments in this update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The adoption of this amendment is not expected to have a material effect on the Company’s consolidated financial statements.

In June 2014, the FASB issued Accounting Standards Update No. 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The guidance in this update changes the accounting for repurchase-to-maturity transactions and repurchase financing arrangements. It also requires enhanced disclosures about repurchase agreements and other similar transactions. The accounting changes in this update are effective for public companies for the first interim or annual period beginning after December 15, 2014. In addition, for public companies, the disclosure for certain transactions accounted for as a sale is effective for the first interim or annual period beginning on or after December 15, 2014, and the disclosure for transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Early application is not permitted. The adoption of this amendment did not have a material effect on the Company’s consolidated financial statements.

In August 2014, the FASB issued Accounting Standards Update No. 2014-14, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure. This update provides guidance on how to classify and measure certain government-guaranteed mortgage loans upon foreclosure, most commonly those offered by the Federal Housing Administration ("FHA") of the U.S. Department of Housing and Urban Development ("HUD"), and the U.S. Department of Veterans Affairs ("VA"). The ASU requires that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: 1) the loan has a government guarantee that is not separable from the loan before foreclosure; 2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under the claim; and 3) at the time of foreclosure, an amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The accounting changes in this update are effective for public companies for annual periods, and the interim periods within those annual periods, beginning after December 15, 2014. Early application is permitted under certain circumstances. The adoption of this amendment did not have a material effect on the Company’s consolidated financial statements.

In August 2014, the FASB issued Accounting Standards Update No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. The amendments in this update provide guidance in GAAP about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. In doing so, the amendment should reduce diversity in the timing and content of footnote disclosures. Disclosures are required if it is probable an entity will be unable to meet its obligations within the look-forward period of twelve months after the financial statements are made available. Incremental substantial doubt disclosure is required if the probability is not mitigated by management's plans. The new standard applies to all entities for the first annual period ending after December 15, 2016, and interim periods thereafter. The adoption of this standard is not expected to have a material effect on the Company’s consolidated financial statements.

In July 2015, the FASB announced a delay to the effective date of Accounting Standards Update No. 2014-09, Revenue from Contract with Customers (Topic 606). Reporting entities may choose to adopt the standard as of the original date, or take advantage of a one-year delay. For a public entity, the revised effective date is for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is not permitted prior to the original effective date. The adoption of this amendment is not expected to have a material effect on the Company’s consolidated financial statements.

17.    Subsequent Events

Management evaluated subsequent events through the date the consolidated financial statements were issued. Events or transactions occurring after June 30, 2015, but prior to the date the consolidated financial statements were issued, that provided additional evidence about conditions that existed at June 30, 2015 have been recognized in the consolidated financial statements for the period ended June 30, 2015. Events or transactions that provided evidence about conditions that did not exist at June 30, 2015, but arose before the consolidated financial statements were issued, have not been recognized in the consolidated financial statements for the period ended June 30, 2015.

On July 16, 2015, the board of directors of the Company declared a cash dividend of $0.15 per share payable on September 15, 2015 to shareholders of record as of the close of business on September 1, 2015.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

OVERVIEW

The Company provides financial services to individuals, businesses, governmental units and institutional customers located primarily in the upper Midwest, through its two bank subsidiaries. MidWestOne Bank has office locations in central and east-central Iowa, while Central Bank has office locations in the Twin Cities area of Minnesota, Wisconsin, and Florida. MidWestOne Insurance Services, Inc. provides personal and business insurance services in Iowa. MidWestOne Bank and Central Bank are 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 Division of MidWestOne Bank administers estates, personal trusts, conservatorships, and pension and profit-sharing accounts along with providing brokerage and other investment management services to customers.

We operate as independent community banks that offer a broad range of customer-focused financial services as an alternative to large regional banks in our market area. Management has invested in infrastructure and staffing to support our strategy of serving the financial needs of businesses, individuals and municipalities in our market area. We focus our efforts on core deposit generation, especially transaction accounts, and quality loan growth with an emphasis on growing commercial loan balances. We seek to maintain a disciplined pricing strategy on deposit generation that will allow us to compete for high quality loans while maintaining an appropriate spread over funding costs.

Our results of operations depend primarily on our net interest income, which is the difference between the interest income on our earning assets, such as loans and securities, and the interest expense paid on our deposits and borrowings. Results of operations are also affected by non-interest income and expense, the provision for loan losses and income tax expense. Significant external factors that impact our results of operations include general economic and competitive conditions, as well as changes in market interest rates, government policies, and actions of regulatory authorities.

The following discussion and analysis should be read in conjunction with the consolidated financial statements and related notes and with the statistical information and financial data appearing in this report as well as our 2014 Annual Report on Form

37

10-K. Results of operations for the three- and six month periods ended June 30, 2015 are not necessarily indicative of results to be attained for any other period.

Merger with Central Bancshares, Inc.

On May 1, 2015, the Company completed the Central merger, pursuant to which Central was merged with and into the Company. In connection with the merger, Central Bank, a Minnesota-chartered commercial bank and wholly-owned subsidiary of Central, became a wholly-owned subsidiary of the Company.

The Company issued 2,723,083 shares of common stock and paid $64.0 million in cash, for total estimated consideration of $136.6 million, in connection with the merger. The results of operations acquired from Central have been included in the Company's results of operations for the 60 days since the date of acquisition.

Critical Accounting Policies

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, application of purchase accounting, goodwill and 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 June 30, 2015, was adequate to absorb probable losses in the existing portfolio.

Application of Purchase Accounting

In May 2015 we completed the acquisition of Central, which generated significant amounts of fair value adjustments to assets and liabilities and related amortization. The fair value adjustments assigned to assets and liabilities, as well as their related useful lives, are subject to judgment and estimation by our management. Goodwill and intangibles related to acquisitions are determined and based on purchase price allocations. Valuation of intangible assets is generally based on the estimated cash flows related to those assets, while the initial value assigned to goodwill is the residual of the purchase price over the fair value of all identifiable assets acquired and liabilities assumed. Useful lives are determined based on the expected future period of the benefit of the asset or liability, the assessment of which considers various characteristics of the asset or liability, including the historical cash flows. Due to the number of estimates involved related to the allocation of purchase price and determining the appropriate useful lives, we have identified purchase accounting as a critical accounting policy.

Goodwill and Intangible Assets

Goodwill and intangible assets arise from purchase business combinations. In May 2015, we completed our merger with Central. We were deemed to be the purchaser for accounting purposes and thus recognized goodwill and other intangible assets in connection with the merger. The goodwill was assigned to our Central Bank reporting unit. As a general matter, goodwill and other 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 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. Periodically 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. See Note 7. "Goodwill and Intangible Assets" to our consolidated financial statements for additional information related to our intangible assets.

38

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

Comparison of Operating Results for the Three Months Ended June 30, 2015 and June 30, 2014

Summary

For the quarter ended June 30, 2015, we earned net income of$4.5 million, which was a decrease of$0.3 millionfrom$4.8 million for the quarter ended June 30, 2014. Basic and diluted earnings per common share for the second quarter of 2015 were each $0.43and$0.42, respectively, versus$0.56for both basic and diluted earnings per common sharein the second quarter of 2014. After excluding the effects of $2.7 million ($2.3 million after tax) of expenses related to the merger with Central, adjusted diluted earnings per share for the second quarter of 2015 were $0.66. Our annualized Return on Average Assets ("ROAA") for the second quarter of 2015 was0.70%compared with a ROAA of1.09%for the same period in 2014. Our annualized Return on Average Shareholders' Equity ("ROAE") was 7.27% for the three months ended June 30, 2015 compared with 10.29% for the three months ended June 30, 2014. The annualized Return on Average Tangible Equity ("ROATE") was 11.21% for the second quarter of 2015 compared with 10.99% for the same period in 2014.

The following table presents selected financial results and measures as of and for the quarter ended June 30, 2015 and 2014.

Net Interest Income

Net interest income is the difference between interest income and fees earned on earning assets and 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 net interest income as a percentage of average earning assets.

Certain assets with tax favorable treatment are evaluated on a tax-equivalent basis. Tax-equivalent basis assumes a federal income tax rate of 35%. Tax favorable assets generally have lower contractual pretax 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.

Our net interest income for the quarter ended June 30, 2015 increased $8.8 million, or 64.0%, from $13.9 million for the second quarter of 2014, primarily due to the merger. An increase in average loan balances, and the effect of the merger-related discount accretion of $1.4 million, resulted in loan interest income increasing by $9.7 million, or 80.6%, to $21.7 million for the second quarter of 2015 compared to the second quarter of 2014. Income from investment securities decreased to $3.3 million for the second quarter of 2015 compared to $3.6 million for the second quarter of 2014, reflective of a decrease of $14.8 million in the average balance of investment securities, and a decrease of 0.15% in the average yield on investment securities between the two comparable periods. Income from loan pool participations was $0.2 million for the second quarter of 2015, a decrease of $0.4 million compared to the same period a year ago, on a significantly lower level of investment in 2015. The Company sold its

40

remaining loan pool participations in June 2015, and has completely exited this line of business. The Company entered into the loan pool participation business upon consummation of a prior merger in March 2008, and had a gross balance of $21.5 million of loan pool participations at December 31, 2014.

Interest expense increased $0.2 million, or 6.1%, to $2.5 million for the second quarter of 2015, compared to $2.3 million for the same period in 2014, primarily due to the additional cost of merger-related assumptions of debt, partially offset by the lower expense on Federal Home Loan Bank (“FHLB”) borrowings which resulted from the decrease of $15.0 million in outstanding FHLB advances between December 31, 2014 and June 30, 2015, and the merger-related amortization of the purchase accounting premium on certificates of deposit in the amount of $0.6 million.

The following table sets forth an analysis of volume and rate changes in interest income and interest expense on our average earning assets and average interest-bearing liabilities during the three months ended June 30, 2015, compared to the same period in 2014, reported on a fully tax-equivalent basis assuming a 35% tax rate. The table distinguishes between the changes related to average outstanding balances (changes in volume holding the initial interest rate constant) and the changes related to average interest rates (changes in average rate holding the initial outstanding balance constant). The change in interest due to both volume and rate has been allocated to volume and rate changes in proportion to the relationship of the absolute dollar amounts of the change in each.

Interest income and fees on loans on a tax-equivalent basis in the second quarter of 2015 increased $9.8 million, or 79.5%, compared with the same period in 2014. This increase reflects the effect of the merger-related accretion of $1.4 million of discount on loans. Average loans were $715.1 million, or 66.0%, higher in the second quarter of 2015 compared with the second quarter of 2014, due primarily to the merger with Central. The yield on our loan portfolio is affected by the amount of nonaccrual loans (which do not earn interest income), the mix of the portfolio (real estate loans generally have a lower overall yield than commercial and agricultural loans), the effects of competition and the interest rate environment on the amounts and volumes of new loan originations, and the mix of variable-rate versus fixed-rate loans in our portfolio. While the increase in interest income was primarily the result of the larger loan portfolio, the average rate on loans increased from 4.55% in the second quarter of 2014 to 4.92% in the second quarter of 2015, primarily due to market conditions in the areas served by Central Bank.

Interest and discount income on loan pool participations was $0.2 million for the second quarter of 2015, a decrease of $0.4 million, or 66.5%, from $0.5 million in the second quarter of 2014. The Company entered into this business upon consummation of a prior merger in March 2008. These loan pool participations were investments in pools of performing, subperforming and nonperforming loans purchased at varying discounts to the aggregate outstanding principal amount of the underlying loans. The loan pool participations were held and serviced by a third-party independent servicing corporation, and the amount of income received from them varied widely due to unpredictable payment collections and loss recoveries. The Company sold its remaining loan pool participations in the second quarter of 2015.

Interest income on investment securities on a tax-equivalent basis totaled $4.0 million in the second quarter of 2015 compared with $4.4 million for the same period of 2014. The tax-equivalent yield on our investment portfolio in the second quarter of 2015 decreased to 3.12% from 3.27% in the comparable period of 2014, reflecting the acquisition of the Central portfolio at fair value on May 1, 2015. The average balance of investments in the second quarter of 2015 was $519.5 million compared with $534.2 million in the second quarter of 2014, a decrease of $14.8 million, or 2.8%. The decrease in average balance resulted primarily from using proceeds from the sale and maturity of securities to pay the cash portion of the merger consideration for the closing of the merger with Central.

43

Interest expense on deposits was substantially unchanged in the second quarter of 2015 compared with the same period in 2014, despite the addition of over $1.0 billion of deposits resulting from the Central merger. The weighted average rate paid on interest-bearing deposits was 0.40% in the second quarter of 2015 compared with 0.58% in the second quarter of 2014. This decline reflects the merger-related amortization of the purchase accounting premium on certificates of deposit in the amount of $0.6 million. Average interest-bearing deposits for the second quarter of 2015 increased $498.9 million compared with the same period in 2014, due primarily to the merger.

Interest expense on borrowed funds of $0.8 million was $0.1 million higher in the second quarter of 2015 compared with the same period in 2014, due to increased balances. Average borrowed funds for the second quarter of 2015 were $24.1 million higher compared with the same period in 2014. This increase was primarily due to the borrowing of $25.0 million in new long-term debt as well as $21.6 million of subordinated notes assumed in the merger in the second quarter of 2015, and despite the $10.4 million decrease in the average level of FHLB borrowing, and repayment of $12.3 million of subordinated debt assumed in the merger in the second quarter of 2015. The weighted average rate on borrowed funds increased to 1.54% for the second quarter of 2015 compared with 1.43% for the second quarter of 2014, reflecting the increased cost of new debt relative to that of pre-merger debt.

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 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 charge off a loan balance, such write-off is charged against the allowance for loan losses.

We recorded a provision for loan losses of $0.9 million in the second quarter of 2015, an increase of $0.6 million, or 200.3%, from $0.3 million in the second quarter of 2014. The increased provision reflects the increase in outstanding loan balances. Net loans charged off in the second quarter of 2015 totaled $0.3 million, the same as net loans charged off in the second quarter of 2014. We determine an appropriate provision based on our evaluation of the adequacy of the allowance for loan losses in relationship to a continuing review of problem loans, current economic conditions, actual loss experience and industry trends. We believe that the allowance for loan losses was adequate based on the inherent risk in the portfolio as of June 30, 2015; however, there is no assurance losses will not exceed the allowance, and any growth in the loan portfolio and the uncertainty of the general economy may require additional provisions in future periods as deemed necessary.

Sensitive assets include nonaccrual loans, loans on MidWestOne Bank's and Central Bank's watch loan reports and other loans identified as having higher potential for loss. We review sensitive assets on at least a quarterly basis for changes in the customers' ability to pay and changes in the valuation of underlying collateral in order to estimate probable losses. We also periodically review a watch loan list which is comprised of loans that have been restructured or involve customers in industries which have been adversely affected by market conditions. The majority of these loans are being repaid in conformance with their contracts.

* Total revenue is net interest income plus noninterest income excluding gain/loss on securities and premises and equipment and impairment of investment securities.

Total noninterest income increased $1.5 million for the second quarter of 2015 compared with the same period for 2014 due primarily to the merger. The increase, while broadly based, was primarily in mortgage origination and loan servicing fees, which rose $0.5 million, or 161.9%, from $0.3 million for the second quarter of 2014 to $0.8 million for the second quarter of 2015.

44

Noninterest income in the second quarter of 2015 was also driven by increased gains on sale of investment securities of $0.3 million compared to the second quarter of 2014. Other service charges, commissions and fees increased by $0.2 million, or 42.2%, from $0.6 million in the second quarter of 2014 compared to $0.8 million for the second quarter of 2015, despite the inclusion of $0.4 million of net loss realized on the sale of the loan pool participations.

Management's strategic goal is for noninterest income to constitute 25% of total revenues (net interest income plus noninterest income excluding gain/loss on securities and premises and equipment and impairment of investment securities) over time. For the three months ended June 30, 2015, noninterest income comprised 17.0% of total revenues, compared with 19.6% for the same period in 2014. With the recent acquisition of Central Bank, management expects to see gradual improvement in this ratio in future periods.

Total noninterest expense	$	19,846	$	10,639	$	9,207	86.5	%

Noninterest expense for the second quarter of 2015 was $19.8 million, up $9.2 million, or 86.5%, from the second quarter of 2014. The increase was mainly due to expenses relating to the Central merger and the increased size of the Company following the merger. Salaries and employee benefits increased $3.9 million, or 64.9%, between the second quarter of 2014 and the second quarter of 2015 mainly as a result of the merger-related increase in the number of employees. Merger-related expenses were $2.7 million ($2.3 million after tax), the majority of which were professional fees expense, which increased $1.5 million, or 186.1%, for the second quarter of 2015, compared with the second quarter of 2014. Other operating expense for the second quarter of 2015 increased $1.6 million, or 114.4%, compared with the second quarter of 2014, primarily due to merger-related expenses and the net loss of $0.4 million on the sale of the loan pool participations in June 2015.

Income Tax Expense

Our effective income tax rate, or income taxes divided by income before taxes, was 36.7% for the second quarter of 2015, which was higher than the effective tax rate of 26.6% for the second quarter of 2014. Income tax expense was $2.6 million in the second quarter of 2015 compared to $1.7 million for the same period of 2014. The primary reason for the increase in both tax rate and tax expense is non-deductible merger-related expenses incurred in the second quarter of 2015 and not in the second quarter of 2014.

Comparison of Operating Results for the Six Months Ended June 30, 2015 and June 30, 2014

Summary

For the six months ended June 30, 2015, we earned net income of$9.3 million,compared with$9.7 millionfor the six months ended June 30, 2014, a decrease of4.7%.

After excluding the effects of $3.2 million ($2.7 million after tax) of expenses related to the previously announced merger with Central, adjusted diluted earnings per share for the first six months of 2015 were $1.28. Our annualized ROAA for the first six months of 2015 was 0.86% compared with 1.12% for the same period in 2014. Our annualized ROAE was 8.46% for the six months ended June 30, 2015 versus 10.70% for the six months ended June 30, 2014. The annualized ROATE was 10.89% for the first six months of 2015 compared with 11.44% for the same period in 2014.

Net Interest Income

Our net interest income for the six months ended June 30, 2015 was $37.0 million, $9.6 million, or 35.0%, greater than our net interest income reported for the six months ended June 30, 2014, primarily due to the merger. Our total interest income of $41.7 million was $9.6 million higher in the first six months of 2015 compared with the same period in 2014. The increase in total interest income was driven by increases in interest and fees on loans, partially offset by lower income on investment securities. Income from loans increased from $23.9 million in the first six months of 2014 to $34.3 million in the first six months of 2015 due to a merger-related higher average loan balance and a higher yield, which reflects the effect of the merger-related discount accretion of $1.4 million. Income from loan pool participations was unchanged at $0.8 million for the six months ended June 30, 2014 and the six months ended June 30, 2015. The Company exited this line of business during the second quarter of 2015. Interest income on investment securities decreased $0.7 million, or 10.1%, to $6.6 million for the first six months of 2015 compared to the first six months of 2014. The decrease was primarily due to a lower yield on the investment securities during the first six months of 2015 compared to the same period of 2014. Total interest expense for the first six months of 2015 was virtually unchanged compared with the same period in 2014, despite the merger-related increase in average balances. Our net interest margin on a tax-equivalent basis for the first six months of 2015 improved to 3.92% compared with 3.59% for the first six months of 2014. Net interest margin is a measure of the net return on interest-earning assets and is computed by dividing annualized net interest income on a tax-equivalent basis by the average of total interest-earning assets for the period. Our overall yield on earning assets increased to 4.39% for the first six months of 2015 from 4.16% for the first six months of 2014. This improvement was due primarily to higher yields on loans combined with increased average loan volumes resulting from the merger. The average cost of interest-bearing liabilities decreased in the first six months of 2015 to 0.59% from 0.71% for the first six months of 2014, due primarily to the lower cost of deposit funds in the areas served by Central Bank.

The following table sets forth an analysis of volume and rate changes in interest income and interest expense on our average earning assets and average interest-bearing liabilities during the six months ended June 30, 2015, compared to the same period in 2014, reported on a fully tax-equivalent basis assuming a 35% tax rate. The table distinguishes between the changes related to average outstanding balances (changes in volume holding the initial interest rate constant) and the changes related to average interest rates (changes in average rate holding the initial outstanding balance constant). The change in interest due to both volume and rate has been allocated to volume and rate changes in proportion to the relationship of the absolute dollar amounts of the change in each.

Interest income and fees on loans on a tax-equivalent basis increased$10.5 million, or 42.7%, in the first six months of 2015 compared to the same period in 2014. This increase reflects the effect of the merger-related accretion of $1.4 million of discount on loans. The increase is mainly due to an increase in average loans balances of $393.5 million, or 36.3%, in the first six months of 2015 compared to the same period in 2014, primarily resulting from the merger. This increase was augmented by an increase in the yield of loans from 4.56% in the first six months of 2014 to 4.77% in the same period of 2015, again, primarily due to the merger and the effect of the merger-related discount accretion of $1.4 million. The yield on our loan portfolio is affected by the amount of nonaccrual loans (which do not earn interest income), the mix of the portfolio (real estate loans generally have a lower overall yield than commercial and agricultural loans), the effects of competition and the interest rate environment on the amounts and volumes of new loan originations, and the mix of variable-rate versus fixed-rate loans in our portfolio.

Interest and discount income on loan pool participations was $0.8 million for the first six months of 2015 which was the same as for the first six months of 2014. Average loan pool participations were $5.7 million, or 22.0%, lower in the first six months of 2015 compared to the same period in 2014.The Company sold its remaining loan pool participations in the second quarter of 2015.

Interest income on investment securities on a tax-equivalent basis totaled $8.1 million in the first six months of 2015 compared with $8.8 million for the same period of 2014, mainly due to lower yields on investment securities. The tax-equivalent yield on our investment portfolio for the first six months of 2015decreased to 3.21% from 3.29% in the comparable period of 2014. The average balance of investments in the first six months of 2015 was $505.6 million compared with $537.4 million in the first six months of 2014, a decrease of $31.7 million, or 5.9%. The decrease in average balance resulted primarily from using proceeds from the sale and maturity of securities to pay the cash portion of the merger consideration for the closing of the merger with Central.

Interest expense on deposits was substantially unchanged for the first six months of 2015 compared with the same period in 2014. The weighted average rate paid on interest-bearing deposits was 0.48% for the first six months of 2015 compared with

49

0.59% for the first six months of 2014. This decline reflects the merger-related amortization of the purchase accounting premium on certificates of deposit in the amount of $0.6 million. Average interest-bearing deposits for the first six months of 2015increased$263.7 million, or 22.8%, compared with the same period in 2014, due primarily th the merger.

Interest expense on borrowed funds in the first six months of 2015 was $1.3 million, virtually unchanged compared with the same period in 2014, despite higher average balances. Average borrowed funds for the first six months of 2015 were $4.4 millionhigher compared with the same period in 2014. This increase was primarily due to the borrowing of $25.0 million in new long-term debt as well as $21.6 million of subordinated notes assumed in the merger during the second quarter of 2015, and despite the $16.8 milliondecrease in the average level of FHLB borrowings for the first six months of 2015 compared to the first six months of 2014. The weighted average rate on borrowed funds decreased to 1.41% for the first six months of 2015 compared with 1.45% for the first six months of 2014.

Provision for Loan Losses

We recorded a provision for loan losses of $1.5 million in the first six months of 2015, $0.7 million, or 100.1%, more than the $0.8 million provision in the first six months of 2014. Net loans charged off in the first six months of 2015 totaled $0.7 million compared with $0.5 million in the first six months of 2014. The increased provision reflects the increase in outstanding loan balances.

Total noninterest income rose to $9.1 million for the six months ended June 30, 2015, an increase of $1.3 million, or 17.0%, from $7.8 million during the same period of 2014. While all but one of the major noninterest income categories improved, primarily due to the merger, the greatest increase for the six months ended June 30, 2015, was in service charges and fees on deposit accounts, with an increase of $0.3 million to $1.8 million, compared with $1.5 million for the same period of 2014. Mortgage origination and loan servicing fees in the six months ended June 30, 2015 increased $0.3 million, or 41.9%, from $0.8 million for the same period in 2014. Another significant contributor to the overall increase in noninterest income was improvement in trust, investment, and insurance fees, which increased to $3.2 million for the six months ended June 30, 2015, an improvement of $0.3 million, or 9.0%, from $2.9 million for the same period in 2014.

Management's strategic goal is for noninterest income to constitute 25% of total revenues (net interest income plus noninterest income excluding gain/loss on securities and premises and equipment and impairment of investment securities) over time. For the six months ended June 30, 2015, noninterest income comprised 18.0% of total revenues, compared with 19.9% for the same period in 2014. With the recent acquisition of Central Bank, management expects to see gradual improvement in this ratio in future periods.

Total noninterest expense	$	31,025	$	21,031	$	9,994	47.5	%

Noninterest expense increased to $31.0 million for the six months ended June 30, 2015 compared with $21.0 million for the six months ended June 30, 2014, an increase of $10.0 million, or 47.5%. As with the quarterly expenses, the increase was mainly due to the inclusion of expenses related to the closing of the merger and two months of post-merger expenses, and the net loss of $0.4 million on the sale of the loan pool participations in June 2015. Salaries and employee benefits increased $4.7 million, or 38.3%, from the six months ended June 30, 2014 to the six months ended June 30, 2015 due primarily to the merger-related increase in the number of employees.. Merger-related expenses paid were $3.2 million ($2.7 million after tax). These expenses are reflected mainly in an increase in professional fees expense of $1.6 million during the six months ended June 30, 2015, compared to the six months ended June 30, 2014, and an increase of $1.7 million, or 61.8%, in other operating expense for the first six months of 2015 compared to the same period a year ago.

Income Tax Expense

Our effective tax rate, or income taxes divided by income before taxes, was 31.5% for the first six months of 2015, and 27.3% for the first six months of 2014. Income tax expense increased to $4.3 million in the first six months of 2015 compared with $3.6 million for the same period of 2014, primarily due to the non-deductible merger-related expenses incurred in the current period.

FINANCIAL CONDITION

Due to the merger, total assets increased to $2.92 billion at June 30, 2015 from $1.80 billion at December 31, 2014. The main areas of asset increases were loans, cash and cash equivalents, premises and equipment, and goodwill and other intangibles. These increases were partially offset by a decrease in loan pool participations due to the sale of the entire portfolio in June 2015. Total deposits at June 30, 2015, were $2.40 billion, an increase of $995.8 million from December 31, 2014, due primarily to the merger. The deposit increase was concentrated in interest-bearing checking deposits, which increased $375.9 million, or 60.8%, to $994.4 million at June 30, 2015, from $618.5 million at December 31, 2014, and non-interest-bearing demand deposits, which increased $313.5 million, or 146.2% between these two dates. Junior subordinated notes issued to capital trusts increased by $8.1 million, or 52.1%, between December 31, 2014 and June 30, 2015, due to the assumption of notes in the merger with Central. The Company initiated new long-term borrowings from an unaffiliated bank of $25.0 million during the second quarter of 2015 in connection with the closing of the merger. These increases were somewhat offset by a decrease in FHLB borrowings of $15.0 million, or 16.1%, to $78.0 million, between December 31, 2014 and June 30, 2015. The amounts recognized in the financial statements for the merger have been determined only provisionally, with the Company having up to one year to finalize them. See Note 2. "Business Combination" to our consolidated financial statements for additional information related to our merger.

Investment Securities

Investment securities totaled $528.6 million at June 30, 2015, or 18.1% of total assets, an increase of $2.2 million, or 0.4%, from $526.5 million, or 29.2% of total assets, as of December 31, 2014. A total of $429.9 million of the investment securities were classified as available for sale at June 30, 2015, compared to $474.9 million at December 31, 2014. Investment securities available for sale decreased $45.1 million, or 9.49% from December 31, 2014 to June 30, 2015 due to the sale of securities to pay the cash portion of the merger consideration for the closing of the merger with Central. As of June 30, 2015, the portfolio consisted mainly of obligations of states and political subdivisions (44.0%), mortgage-backed securities and collateralized mortgage obligations (39.2%), and obligations of U.S. government agencies (5.4%). Investment securities held to maturity were $98.7 million at June 30, 2015, compared to $51.5 million at December 31, 2014. The increase of $47.2 million, or 91.7%, in held to maturity investments was due to the merger.

Loans

The composition of loans (before deducting the allowance for loan losses) was as follows:

	June 30, 2015				December 31, 2014
	Balance		% of Total		Balance		% of Total
(dollars in thousands)
Agricultural	$	113,850	5.4	%	$	104,809	9.3	%
Commercial and industrial	448,406		21.3		303,108		26.7
Credit cards	1,348		—		1,246		0.1
Overdrafts	1,450		0.1		744		0.1
Commercial real estate:
Construction and development	117,402		5.5		59,383		5.2
Farmland	88,143		4.2		83,700		7.4
Multifamily	111,613		5.3		54,886		4.8
Commercial real estate-other	651,202		30.9		228,552		20.2
Total commercial real estate	968,360		45.9		426,521		37.6
Residential real estate:
One- to four- family first liens	435,631		20.7		219,314		19.4
One- to four- family junior liens	104,078		4.9		53,297		4.7
Total residential real estate	539,709		25.6		272,611		24.1
Consumer	35,235		1.7		23,480		2.1
Total loans	$	2,108,358	100.0	%	$	1,132,519	100.0	%

Total loans (excluding loan pool participations and loans held for sale) increased $975.8 million, or 86.2%, from December 31, 2014, to $2.11 billion at June 30, 2015 primarily as a result of the merger. While all but one loan category saw increased balances, the increases were primarily concentrated in commercial real estate-other, one-to-four-family first liens, and commercial and industrial loans. As of June 30, 2015, the largest category of bank loans was commercial real estate loans, comprising approximately 46% of the portfolio, which included 4% of total loans being farmland, 6% being construction and development, and 5% being multifamily residential mortgages. Residential real estate loans was the next largest category at 26% of total loans, followed by commercial and industrial loans at 21%, agricultural loans at 5%, and consumer loans at 2%. As of June 30, 2015, our loan to deposit ratio was 87.7% compared with a loan to deposit ratio of 80.4% at December 31, 2014 (excluding loan pool participations). We anticipate that the loan to deposit ratio will remain relatively stable in future periods, with both loans and deposits increasing in the post-merger environment.

We have minimal direct exposure to subprime mortgages in our loan portfolio. Our loan policy provides a guideline that real estate mortgage borrowers have a Beacon score of 640 or greater. Exceptions to this guideline have been noted but the overall exposure is deemed minimal by management. Mortgages we originate and sell on the secondary market are typically underwritten according to the guidelines of secondary market investors. These mortgages are sold on a non-recourse basis.

Loan Pool Participations

As of June 30, 2015, we had no loan pool participations, net, down from $19.3 million at December 31, 2014. This decrease was due to the sale of the complete investment to an unaffiliated purchaser during the second quarter of 2015, with a net loss on sale of $0.4 million. Loan pool participations were participation interests in performing, subperforming and nonperforming loans that had been purchased from various non-affiliated banking organizations. The Company entered into this business upon consummation of a prior merger in March 2008.

52

Premises and Equipment

As of June 30, 2015, premises and equipment totaled $71.3 million, an increase of $33.5 million, or 88.7%, from $37.8 million at December 31, 2014. This increase was primarily due to the merger with Central as well as two ongoing major construction projects, both in our Iowa City market. As part of the merger with Central we acquired 13 banking locations in Minnesota, 7 banking locations in Wisconsin, and 2 banking locations in Florida. In August 2013, we entered into a contract for the restoration and remodeling of the building which serves as the main office of MidWestOne Bank and headquarters of the Company. The estimated cost of the restoration and remodeling is $13.8 million, and it is anticipated that the project will be completed in April 2016. In December 2013, we entered into a contract for the construction of a new Home Mortgage Center with an estimated cost of design and construction of $16.0 million, and with completion anticipated in the fourth quarter of 2015. As of June 30, 2015, an estimated $9.9 million remained to be paid on these contracts. We expect the balance of premises and equipment to continue rising in the future as these projects progress towards completion in the remainder of 2015 and 2016.

Deposits

Total deposits as of June 30, 2015 were $2.40 billion, an increase of $995.8 million, or 70.7%, from $1.41 billion as of December 31, 2014. The increase was primarily due to the merger with Central. Interest-bearing checking deposits were the largest category of deposits at June 30, 2015, representing approximately 41.4% of total deposits. Total interest-bearing checking deposits were $994.4 million at June 30, 2015, an increase of $375.9 million, or 60.8%, from $618.5 million at December 31, 2014. Included in interest-bearing checking deposits at June 30, 2015 was $10.9 million of brokered deposits in the Insured Cash Sweep (ICS) program, a decrease of $16.8 million, or 60.7%, from $27.6 million at December 31, 2014, due primarily to a withdrawal by one account holder. Non-interest bearing demand deposits were $528.0 million at June 30, 2015, an increase of $313.5 million, or 146.2%, from $214.5 million at December 31, 2014. Savings deposits increased $84.8 million, or 82.8%, from December 31, 2014 to June 30, 2015. Total certificates of deposit were $694.5 million at June 30, 2015, up $221.5 million, or 46.8%, from $473.0 million at December 31, 2014, again, due to the merger. Included in total certificates of deposit at June 30, 2015 was $4.1 million of brokered deposits in the Certificate of Deposit Account Registry Service (CDARS) program, a decrease of $2.0 million, or 32.2%, from the $6.1 million at December 31, 2014. Based on recent experience, management anticipates that many of the maturing certificates of deposit will not be renewed upon maturity due to the current low interest rate environment. Approximately 86.7% of our total deposits were considered “core” deposits as of June 30, 2015.

Debt

Federal Home Loan Bank Borrowings

FHLB borrowings totaled $78.0 millionas ofJune 30, 2015compared with$93.0 million as of December 31, 2014. We utilize FHLB borrowings as a supplement to customer deposits to fund earning assets and to assist in managing interest rate risk. Thus, if deposits decline, FHLB borrowing may increase to provide necessary liquidity. See Note 11. "Long-term Borrowings" to our consolidated financial statements for additional information related to our FHLB borrowings.

Junior Subordinated Notes Issued to Capital Trusts

Junior subordinated notes that have been issued to capital trusts that issued trust preferred securities were $23.5 millionas of June 30, 2015, an increase of $8.1 million, or 52.1%, from $15.4 million at December 31, 2014. This increase was due to junior subordinated notes that were assumed by us from Central in the recently completed merger. See Note 10. "Subordinated Notes Payable" to our consolidated financial statements for additional information related to our junior subordinated notes.

Long-term Debt

Long-term debt in the form of a $35.0 million unsecured note payable to a correspondent bank was entered into on April 30, 2015 in connection with the payment of the merger consideration at the closing of the Central merger, of which $25.0 million was outstanding as of June 30, 2015. See Note 11. "Long-term Borrowings" to our consolidated financial statements for additional information related to our long-term debt.

Goodwill and Other Intangible Assets

Goodwill increased from zero as of December 31, 2014, to $56.5 million as of June 30, 2015 due to the merger with Central. Other intangible assets increased $14.2 million, or 172.2%, to $22.5 million at June 30, 2015 compared to December 31, 2014, due to the merger-related addition of a $12.8 million core deposit intangible and a $2.8 million trade name intangible, along with normal amortization. See Note 7. "Goodwill and Intangible Assets" to our consolidated financial statements for additional information.

Not included in the loans above as of June 30, 2015, were purchased credit impaired loans with an outstanding balance of $5.5 million, net of a discount of $1.9 million.

Our nonperforming assets totaled $21.4 million as of June 30, 2015, an increase of $6.5 million, or 43.3%, from December 31, 2014, with the increase principally driven by OREO acquired through the merger. The balance of OREO at June 30, 2015 was $8.9 million, an increase of $7.0 million, from $1.9 million of OREO at December 31, 2014. All of the OREO property was acquired through foreclosures, and we are actively working to sell all properties held as of June 30, 2015. OREO is carried at

54

appraised value less estimated cost of disposal at the date of acquisition. Additional discounts could be required to market and sell the properties, resulting in a write down through expense. Nonperforming loans totaled $12.5 million (0.59% of total loans) as of June 30, 2015, compared to $13.0 million (1.15% of total loans) as of December 31, 2014.

At June 30, 2015, nonperforming loans consisted of $3.7 million in nonaccrual loans, $7.5 million in troubled debt restructures (“TDRs”) and $1.3 million in loans past due 90 days or more and still accruing. This compares to nonaccrual loans of $3.3 million, TDRs of $8.9 million, and loans past due 90 days or more and still accruing of $0.8 million at December 31, 2014. The decrease in overall nonperforming loans was primarily due to payments collected from TDR-status borrowers, as well as the movement of two borrowers out of TDR status. Loans 90 days past due and still accruing interest increased$0.4 million between December 31, 2014 and June 30, 2015, while nonaccrual loans increased by $0.4 million between these dates. Loans past due 30 to 89 days and still accruing interest (not included in the nonperforming loan totals) were $7.8 million at June 30, 2015, compared with $3.9 million at December 31, 2014, primarily due to the merger. At June 30, 2015, other real estate owned (not included in nonperforming loans) was $8.9 million, up from $1.9 million of other real estate owned at December 31, 2014, again, as a result of the merger. During the first six months of 2015, the Company added 69 properties to other real estate owned, all as a result of the merger, and had 15 real estate property sales. As of June 30, 2015, the allowance for bank loan losses was $17.2 million, or 0.81% of total loans, compared with $16.4 million, or 1.44% of total bank loans at December 31, 2014. The decrease in the ratio of the allowance for loan losses to total loans was due to the purchased loans acquired in the merger being recorded at estimated fair value on their purchase date without a carryover of the related allowance for loan losses. The allowance for loan losses represented 85.45% of nonperforming loans at June 30, 2015, compared with 125.67% of nonperforming bank loans at December 31, 2014. The Company had net loan charge-offs of $0.7 million in the six months ended June 30, 2015, or an annualized 0.10% of average loans outstanding, compared to net charge-offs of $0.5 million, or an annualized 0.09% of average bank loans outstanding, for the same period of 2014.

Loan Review and Classification Process for Agricultural, Commercial and Industrial, and Commercial Real Estate Loans at MidWestOne Bank:

MidWestOne Bank maintains a loan review and classification process which involves multiple officers of MidWestOne Bank and is designed to assess the general quality of credit underwriting and to promote early identification of potential problem loans. All commercial and agricultural loan officers are charged with the responsibility of risk rating all loans in their portfolios and updating the ratings, positively or negatively, on an ongoing basis as conditions warrant. 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. MidWestOne Bank's loan review department undertakes independent credit reviews of relationships based on either criteria established by loan policy, risk-focused sampling, or random sampling. Loan policy requires 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 grades 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 TDR (regardless of size), the lending officer is then charged with preparing a loan strategy summary worksheet that outlines the background of the credit problem, current repayment status of the loans, current collateral evaluation and a workout plan of action. This plan may include goals to improve the credit rating, assist the borrower in moving the loans to another institution and/or collateral liquidation. All such reports are first presented to regional management and then to the board of directors of MidWestOne Bank by the Executive Vice President, Chief Credit Officer (or a designee) of MidWestOne Bank.

Depending upon the individual facts and circumstances and the result of the Classified/Watch review process, loan officers and/or loan review personnel may categorize the loan relationship as impaired. Once that determination has occurred, the loan officer, in conjunction with regional management, will complete an evaluation of the collateral (for collateral-dependent loans) based upon the estimated collateral value, adjusting for current market conditions and other local factors that may affect collateral value. Loan review personnel may also complete an independent impairment analysis when deemed necessary. These judgmental evaluations may produce an initial specific allowance for placement in the Company's allowance for loan and lease losses

55

calculation. As soon as practical, an updated value estimate of the collateral backing that impaired loan relationship is completed. After the updated value is determined, regional management, with assistance from the loan review department, reviews the valuation and updates the specific allowance analysis for each loan relationship accordingly. The board of directors of MidWestOne Bank on a quarterly basis reviews the Classified/Watch reports including changes in credit grades of 5 or higher as well as all impaired loans, the related allowances and OREO.

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.

Loan Review and Classification Process for Agricultural, Commercial and Industrial, and Commercial Real Estate Loans at Central Bank:

Central Bank has a loan classification process that starts with the relationship managers who are ultimately responsible for properly risk rating the loans in their portfolio. A 9 point scale is used with ratings 1-5 as pass; 6 watch (potential weakness); 7 substandard (well defined weakness); 8 Doubtful and 9 Loss. When a loan officers originates a new loan, renews an existing loan or performs an annual review, either a loan presentation or a summary comment is created which summarizes the current financial condition of that customer. A formal evaluation of its risk rating is done at this time. The lender is also responsible for monitoring their portfolio throughout the course of the year and proactively reacting to changing conditions by making any risk rating adjustments.

On a bi-monthly basis the Chief Executive Officer of Central Bank, Chief Credit Officer of Central Bank and Senior Vice President of Special Assets of Central Bank meet with each Market President and review their watch list, past due report and past due real estate taxes report. The action plans for watch list credits are reviewed at these meetings and adjustments are made as needed. Each watch list credit is labeled either “Retain” or “Exit” with those labeled “Exit” transferred to special assets. On a monthly basis the board of directors of Central Bank reviews: a watch list containing watch list credits greater than $500,000; a summary report of loans removed from the watch list; and a summary report of any additions to the list.

Central Bank engages an outside consultant to conduct independent credit reviews of relationships based on criteria established by policy, risk-focused sampling or random sampling. The individual loan reviews consider borrower and/or guarantor financial strength, most recently available financial information, current/anticipated performance of the loan, appropriateness of credit risk grading, compliance with loan approval requirements, and completeness of loan and collateral documentation. The results of credit reviews are presented to management.

Each 7 rated credit is reviewed for impairment. If the loan is determined to be impaired an impairment worksheet is completed which focuses on updating the collateral values based on the current market conditions. These worksheets are updated on a quarterly basis by either the lender or analyst and reviewed and compiled by credit administration. Credit administration sends the compiled impairment information to the finance department for the allowance calculation.

We anticipate standardizing our loan review and classification process between MidWestOne Bank and Central Bank in the future.

Restructured Loans

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

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

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

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

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

• The borrower receives a reduction of the accrued interest.

56

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

During the six months ended June 30, 2015, the Company restructured no loans by granting a concession to a borrower experiencing financial difficulties.

A loan classified as a troubled debt restructuring will no longer be included in the troubled debt restructuring disclosures in the periods after the restructuring if the loan performs in accordance with the terms specified by the restructuring agreement and the interest rate specified in the restructuring agreement represents a market rate at the time of modification. The specified interest rate is considered a market rate when the interest rate is equal to or greater than the rate the Company is willing to accept at the time of restructuring for a new loan with comparable risk. If there are concerns that the borrower will not be able to meet the modified terms of the loan, the loan will continue to be included in the troubled debt restructuring disclosures.

We consider all TDRs, regardless of whether they are performing in accordance with their modified terms, to be impaired loans when determining our allowance for loan losses. A summary of restructured loans as of June 30, 2015 and December 31, 2014 is as follows:

	June 30,		December 31,
	2015		2014
(in thousands)
Restructured Loans (TDRs):
In compliance with modified terms	$	7,546	$	8,918
Not in compliance with modified terms - on nonaccrual status	500		522
Total restructured loans	$	8,046	$	9,440

Allowance for Loan Losses

Our ALLL as of June 30, 2015 was $17.2 million, which was 0.81% of total loans as of that date. This compares with an ALLL of $16.4 million as of December 31, 2014, which was 1.44% of total loans (excluding loan pool participations) as of that date. The decrease in the ratio of the allowance for loan losses to total loans was due to the purchased loans acquired in the merger being recorded at estimated fair value on their purchase date without a carryover of the related allowance for loan losses. Gross charge-offs for the first six months of 2015 totaled $1.1 million, while recoveries of previously charged-off loans totaled $0.4 million. Annualized net loan charge offs to average loans for the first six months of 2015 was 0.10% compared to 0.09% for the year ended December 31, 2014. As of June 30, 2015, the ALLL was 137.2% of nonperforming loans compared with 125.7% as of December 31, 2014. Based on the inherent risk in the loan portfolio, we believe that as of June 30, 2015, the ALLL was adequate; however, there is no assurance losses will not exceed the allowance, and any growth in the loan portfolio or uncertainty in the general economy may require that management continue to evaluate the adequacy of the ALLL and make additional provisions in future periods as deemed necessary.

There were no changes to our ALLL calculation methodology during the first six months of 2015. 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 respective bank's board of directors on a quarterly basis. At June 30, 2015, there were 17 owner-occupied 1-4 family loans with a LTV ratio of 100% or greater. In addition, there were 102 home equity loans without credit enhancement that had a LTV ratio of 100% or greater. We have the first lien on 41 of these equity loans and other financial institutions have the first lien on the remaining 61. Additionally, there were 77 commercial real estate loans without credit enhancement that exceeded the supervisory LTV guidelines

We review all impaired and nonperforming loans individually on a quarterly basis to determine their level of impairment due to collateral deficiency or insufficient cash-flow based on a discounted cash-flow analysis. At June 30, 2015, TDRs were not a material portion of the loan portfolio. We review loans 90 days and over 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.

Capital Resources

Total shareholders’ equity was $278.0 million as of June 30, 2015, compared to $192.7 million as of December 31, 2014, an increase of $85.2 million, or 44.2%. This increase was primarily attributable to capital acquired in connection with the Central merger, net income of $9.3 million for the first six months of 2015, proceeds from the private placement of 300,000 common shares in the amount of $7.9 million net of $0.5 million of expenses, and a $0.6 million decrease in treasury stock due to the

57

issuance of 28,392 shares of Company common stock in connection with stock compensation plans. These increases were partially offset by the payment of $2.9 million in common stock dividends and a $2.0 million decrease in accumulated other comprehensive income due to market value adjustments on investment securities available for sale. No shares of Company common stock were repurchased in the second quarter of 2015.

Total shareholders' equity was 9.51% of total assets as of June 30, 2015 and was 10.71% as of December 31, 2014. The ratio of tangible equity to tangible assets was 7.21% as of June 30, 2015 and 10.29% as of December 31, 2014. Our Tier 1 capital to risk-weighted assets ratio was 10.55% as of June 30, 2015 and was 13.47% as of December 31, 2014. Risk-based capital guidelines require the classification of assets and some off-balance-sheet items in terms of credit-risk exposure and the measuring of capital as a percentage of the risk-adjusted asset totals. We believe that, as of June 30, 2015, the Company and its two bank subsidiaries met all capital adequacy requirements to which we were subject. As of that date, both bank subsidiaries were “well capitalized” under regulatory prompt corrective action provisions.

In July 2013, the U.S. federal banking authorities approved the implementation of the Basel III regulatory capital reforms and issued rules (the "Basel III Rules") effecting certain changes required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”). The Basel III Rules are applicable to all U.S. banks that are subject to minimum capital requirements, as well as to bank and savings and loan holding companies other than “small bank holding companies” (generally non-public bank holding companies with consolidated assets of less than $1.0 billion). The Basel III Rules not only increase most of the required minimum regulatory capital ratios, but they also introduce a new Common Equity Tier 1 Capital ratio and the concept of a capital conservation buffer. The Basel III Rules also expand the definition of capital as in effect previously by establishing criteria that instruments must meet to be considered Additional Tier 1 Capital (Tier 1 Capital in addition to Common Equity) and Tier 2 Capital. A number of instruments that previously generally qualified as Tier 1 Capital now do not qualify, or their qualifications changed. The Basel III Rules also permitted banking organizations with less than $250.0 billion in assets to retain, through a one-time election, the existing treatment for accumulated other comprehensive income, which previously did not affect regulatory capital. The Company elected to retain this treatment, which reduces the volatility of regulatory capital levels. The Basel III Rules have maintained the general structure of the prompt corrective action framework, while incorporating the increased requirements. The prompt corrective action guidelines were also revised to add the Common Equity Tier 1 Capital ratio. In order to be a “well-capitalized” depository institution under the new regime, a bank and holding company must maintain a Common Equity Tier 1 Capital ratio of 6.5% or more; a Tier 1 Capital ratio of 8% or more; a Total Capital ratio of 10% or more; and a leverage ratio of 5% or more. Generally, financial institutions became subject to the new Basel III Rules on January 1, 2015, with phase-in periods for many of the changes.

We have traditionally disclosed certain non-GAAP ratios and amounts to evaluate and measure our financial condition, including our Tier 1 capital to risk-weighted assets ratio. We believe this ratio provides investors with information regarding our financial condition and how we evaluate our financial condition internally. The following table provides a reconciliation of this non-GAAP measure to the most comparable GAAP equivalent.

On February 15, 2015, 20,900 restricted stock units were granted to certain officers of the Company. Additionally, during the first six months of 2015, 23,123 shares of common stock were issued in connection with the vesting of previously awarded grants of restricted stock units, of which 1,210 shares were surrendered by grantees to satisfy tax requirements, and 925 nonvested restricted stock units were forfeited. 5,269 shares of common stock were issued in connection with the exercise of previously issued stock options.

On May 15, 2015, 6,700 restricted stock units were granted to certain incoming officers of the Company related to the Central merger, and 6,500 restricted stock units were granted to the directors of the Company.

Liquidity

Liquidity management involves meeting the cash flow requirements of depositors and borrowers. We conduct liquidity management on both a daily and long-term basis, and adjust our investments in liquid assets based on expected loan demand, projected loan maturities and payments, estimated cash flows from loan pool participations, expected deposit flows, yields available on interest-bearing deposits, and the objectives of our asset/liability management program. We had liquid assets (cash and cash equivalents) of $46.6 million as of June 30, 2015, compared with $23.4 million as of December 31, 2014. Interest-bearing deposits in banks at June 30, 2015, increased to $6.2 million, an increase of $5.9 million from December 31, 2014. Investment securities classified as available for sale, totaling $429.9 million and $474.9 million as of June 30, 2015 and December 31, 2014, respectively, could be sold to meet liquidity needs if necessary. Additionally, our bank subsidiaries maintain unsecured lines of credit with several correspondent banks and secured lines with the Federal Reserve Bank Discount Window and the FHLB that would allow us to borrow funds on a short-term basis, if necessary. Management believes that the Company had sufficient liquidity as of June 30, 2015 to meet the needs of borrowers and depositors.

Our principal sources of funds were proceeds from the maturity and sale of investment securities, proceeds from long-term debt , and the sale of our loan pool participations. These sources provided partial consideration in the merger transaction with Central. 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

59

competition. We utilize particular sources of funds based on comparative costs and availability. This includes fixed-rate FHLB borrowings that can generally be obtained at a more favorable cost than deposits of comparable maturity. We generally manage the pricing of our deposits to maintain a steady deposit base but from time to time may decide, as we have done in the past, not to pay rates on deposits as high as our competition.

As of June 30, 2015, we had $25.0 million of long-term debt outstanding to an unaffiliated banking organization. See Note 11. "Long-term Borrowings" to our consolidated financial statements for additional information related to our long-term debt. We also have $23.5 million of indebtedness payable under junior subordinated debentures issued to subsidiary trusts that issued trust preferred securities in pooled offerings. See Note 10. "Subordinated Notes Payable" to our consolidated financial statements for additional information related to our junior subordinated notes.

Inflation

The effects of price changes and inflation can vary substantially for most financial institutions. While management believes that inflation affects the growth of total assets, it is difficult to assess its overall impact on the Company. 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”) coincides 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.

Off-Balance-Sheet Arrangements

We are a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of our customers, which include commitments to extend credit, commitments to originate residential mortgage loans held for sale, commercial letters of credit, and standby letters of credit. Commitments to extend credit are agreements to lend to customers at predetermined interest rates, as long as there is no violation of any condition established in the contracts. Our exposure to credit loss in the event of nonperformance by the other party to the commitments to extend credit is represented by the contractual amount of those instruments. We use the same credit policies in making commitments as we do for on-balance-sheet instruments.

Commitments to extend credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. We evaluate each customer's creditworthiness on a case-by-case basis. As of June 30, 2015, outstanding commitments to extend credit totaled approximately $425.4 million. We have established a reserve of $0.1 million, which represents our estimate of probable losses as a result of these transactions. This reserve is not part of our allowance for loan losses. Commitments under standby and performance letters of credit outstanding aggregated $8.5 million as of June 30, 2015. We do not anticipate any losses as a result of these transactions.

Residential mortgage loans sold to others are predominantly conventional residential first lien mortgages originated under our usual underwriting procedures, and are most often sold on a nonrecourse basis. At June 30, 2015, there were approximately $2.9 million of mandatory commitments with investors to sell not yet originated residential mortgage loans. We do not anticipate any losses as a result of these transactions.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

In general, market risk is the risk of change in asset values due to movements in underlying market rates and prices. Interest rate risk is the risk to earnings and capital arising from movements in interest rates. Interest rate risk is the most significant market risk affecting the Company as other types of market risk, such as foreign currency exchange rate risk and commodity price risk, play a lesser role in the normal course of our business activities.

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

Liquidity Risk

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

Net cash inflows from operating activities were $2.9 million in the first six months of 2015, compared with $15.0 million in the first six months of 2014. Net income before depreciation, amortization, and accretion is generally the primary contributor for net cash inflows from operating activities.

Net cash inflows from investing activities were $73.8 million in the first six months of 2015, compared to net cash inflows of $22.5 million in the comparable six-month period of 2014. In the first six months of 2015, investment securities transactions resulted in net cash inflows of $155.8 million, compared to inflows of $22.4 million during the same period of 2014. Increased loan volume accounted for net cash outflows of $60.0 million for the first six months of 2015, compared with $1.7 million of net inflows for the same period of 2014. A net cash outflow of $35.6 million was also experienced in connection with the merger with Central in the first six months of 2015. Purchases of premises and equipment resulted in a $7.0 million cash outflow in the first six months of 2015, compared to outflows of $5.9 million relating to premises and equipment in the comparable period of 2014, both resulting from the two large building projects currently underway to restore and remodel the main office of MidWestOne Bank and headquarters of the Company, and to construct a new Home Mortgage Center. Cash inflows from loan pool participations were $19.3 million during the first six months of 2015 compared to $4.1 million during the same period of 2014, as we sold our interest in these instruments in the second quarter of 2015.

Net cash used in financing activities in the first six months of 2015 was $53.5 million, compared with net cash used of $40.1 million for the same period of 2014. The largest financing cash outflows during the six months ended June 30, 2015 was the net decrease in deposits of $53.4 million, compared to a net decrease of $27.3 million in the first six months of 2014. Other cash outflows included the repayment of a subordinated note in the amount of $12.7 million, a net decrease of $15.0 million in FHLB borrowings, and the use of $2.9 million to pay dividends. Sources of cash inflows during the first six months of 2015 included proceeds from long-term debt of $25.0 million, proceeds from the private placement sale of Company stock in the amount of $7.9 million, net of expenses, and the increase of $7.3 million in federal funds purchased.

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

•Federal Funds Lines

•FHLB Borrowings

•Brokered Deposits

•Brokered Repurchase Agreements

•Federal Reserve Bank Discount Window

Federal Funds Lines:

Routine liquidity requirements are met by fluctuations in the federal funds position of both MidWestOne Bank and Central Bank. The principal function of these funds is to maintain short-term liquidity. Unsecured federal 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 federal funds sold exposure to any one customer is continuously monitored. The current federal funds purchased limit is 10% of total assets, or the amount of established federal funds lines, whichever is smaller.

61

Currently, MidWestOne Bank and Central Bank have unsecured federal funds lines totaling $75.0 million, which lines are tested annually to ensure availability.

FHLB Borrowings:

FHLB borrowings provide both a source of liquidity and long-term funding for both MidWestOne Bank and Central Bank. Use of this type of funding is coordinated with both the strategic balance sheet growth projections and interest rate risk profile of MidWestOne Bank and Central Bank. Factors that are taken into account when contemplating use of FHLB borrowings are the effective interest rate, the collateral requirements, community investment program credits, and the implications and cost of having to purchase incremental FHLB stock. The current FHLB borrowing limit is 35% of total assets. As of June 30, 2015, MidWestOne Bank and Central Bank had $78.0 million in outstanding FHLB borrowings, leaving $252.0 million available for liquidity needs, based on collateral capacity. These borrowings are secured by various real estate loans (residential, commercial and agricultural).

Brokered Deposits:

MidWestOne Bank and Central Bank have brokered certificate of deposit 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 outside of the respective bank's core market area, is reflected in an internal policy stating that MidWestOne Bank and Central Bank limit the use of brokered deposits as a funding source to no more than 10% of total assets. Board approval is required to exceed this limit. MidWestOne Bank and Central 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 them from using brokered deposits altogether.

Brokered Repurchase Agreements:

Brokered repurchase agreements may be established with approved brokerage firms and banks. Repurchase agreements create rollover risk (the risk that a broker will discontinue the relationship due to market factors) and are not used as a long-term funding solution, especially when used to fund long-term assets. Collateral requirements and availability are evaluated and monitored. The current policy limit for brokered repurchase agreements is 10% of total assets. There were no outstanding brokered repurchase agreements at June 30, 2015.

Federal Reserve Bank Discount Window:

The Federal Reserve Bank Discount Window is another source of liquidity, particularly during difficult economic times. MidWestOne Bank and Central Bank each have a borrowing capacity with the Federal Reserve Bank of Chicago limited by the amount of municipal securities pledged against the line. As of June 30, 2015, the banks had combined municipal securities with an approximate market value of $12.9 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 Asset/Liability Management Policy of both MidWestOne Bank and Central Bank. The change in the Company’s interest rate profile between December 31, 2014 and June 30, 2015 is largely attributable to the acquisition of Central. The Company liquidated certain investment securities in order to provide for the cash portion of the deal consideration. Selling fixed-rate securities made the organization less liability sensitive. In addition, Central Bank’s interest rate risk position is asset sensitive - more than off-setting the Company’s heretofore modest liability sensitivity.

Like most financial institutions, our 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, variances 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. Our asset and liability committee seeks to manage interest rate risk under a variety of rate environments by structuring our balance sheet and off-balance-sheet positions in such a way that changes in interest rates do not have a large negative impact. The risk is monitored and managed within approved policy limits.

62

We use a third-party service to model and measure our exposure to potential interest rate changes. For various assumed hypothetical changes in market interest rates, numerous other assumptions are made, such as prepayment speeds on loans and securities backed by mortgages, the slope of the Treasury yield-curve, the rates and volumes of our deposits, and the rates and volumes of our loans. This analysis measures the estimated change in net interest income in the event of hypothetical changes in interest rates. The following table presents our projected changes in net interest income for the various interest rate shock levels at June 30, 2015 and December 31, 2014.

Analysis of Net Interest Income Sensitivity

	Immediate Change in Rates
	-200			-100			+100			+200
(dollars in thousands)
June 30, 2015
Dollar change	$	(3,994	)	$	(1,655	)	$	1,162		$	3,590
Percent change	(4.1		)%	(1.7		)%	1.2		%	3.7		%
December 31, 2014
Dollar change	$	(315	)	$	171		$	(369	)	$	(491	)
Percent change	(0.6		)%	0.3		%	(0.7		)%	(0.9		)%

As shown above, at June 30, 2015, the effect of an immediate and sustained 200 basis point increase in interest rates would be an increase our net interest income by approximately $3.6 million. The effect of an immediate and sustained 200 basis point decrease in rates would decrease our net interest income by approximately $4.0 million. These changes in net interest income under various interest rate scenarios are small relative to the overall level of net interest income.  In fact, changes of this magnitude are well within the range of what would be considered neutral interest rate sensitivity. In the current low interest rate environment, model results of a 200 basis point drop in interest rates are of questionable value as many interest-bearing liabilities and interest-earning assets cannot re-price significantly lower than current levels. As part of a strategy to mitigate net interest 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 our net interest 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 0.0% 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.

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.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

Under supervision and with the participation of certain members of our management, including our chief executive officer and chief financial officer, we completed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of June 30, 2015. Based on this evaluation, our chief executive officer and chief financial officer have concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report with respect to timely communication to them and other members of management responsible for preparing periodic reports of material information required to be disclosed in this report as it relates to the Company and our consolidated subsidiaries.

The effectiveness of our or any system of disclosure controls and procedures is subject to certain limitations, including the exercise of judgment in designing, implementing, and evaluating the controls and procedures, the assumptions used in identifying the likelihood of future events, and the inability to eliminate misconduct completely. As a result, there can be no assurance that our disclosure controls and procedures will prevent all errors or fraud or ensure that all material information will be made known to appropriate management in a timely fashion. By their nature, our or any system of disclosure controls and procedures can provide only reasonable assurance regarding management's control objectives.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Special Cautionary Note Regarding Forward-Looking Statements

This report contains certain “forward-looking statements” within the meaning of such term in the Private Securities Litigation Reform Act of 1995. We and our representatives may, from time to time, make written or oral statements that are “forward-looking” and provide information other than historical information. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results to be materially different from any results, levels of activity, performance or achievements expressed or implied by any forward-looking statement. These factors include, among other things, the factors listed below.

Forward-looking statements, which may be based upon beliefs, expectations and assumptions of our management and on information currently available to management, are generally identifiable by the use of words such as “believe”, “expect”, “anticipate”, “should”, “could”, “would”, “plans”, “intend”, “project”, “estimate”, “forecast”, “may” or similar expressions. These forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those expressed in, or implied by, these statements. Readers are cautioned not to place undue reliance on any such forward-looking statements, which speak only as of the date made. Additionally, we undertake no obligation to update any statement in light of new information or future events, except as required under federal securities law.

Our ability to predict results or the actual effect of future plans or strategies is inherently uncertain. Factors that could have an impact on our ability to achieve operating results, growth plan goals and future prospects include, but are not limited to, the following:

• credit quality deterioration or pronounced and sustained reduction in real estate market values could cause an increase in our allowance for credit losses and a reduction in net earnings;

• the risks of mergers, including with Central, 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;

• 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 the Basel III Rules, which became effective January 1, 2015), 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;

• the effects of competition from other commercial banks, thrifts, mortgage banking firms, consumer finance companies, credit unions, securities brokerage firms, insurance companies, money market and other mutual funds, and other financial institutions operating in our markets or elsewhere or providing similar services;

• the failure of assumptions underlying the establishment of allowances for loan losses and estimation of values of collateral and various financial assets and liabilities;

• volatility of rate-sensitive deposits;

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

• asset/liability matching risks and liquidity risks;

• 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 FASB; and

• other factors and risks described under “Risk Factors” in our Annual Report on Form 10-K for the period ended December 31, 2014.

We qualify all of our forward-looking statements by the foregoing cautionary statements. Because of these risks and other uncertainties, our actual future results, performance or achievement, or industry results, may be materially different from the

64

results indicated by these forward-looking statements. In addition, our past results of operations are not necessarily indicative of our future results.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

The Company and its subsidiaries are from time to time parties to various legal actions arising in the normal course of business. We believe that there are no threatened or pending proceedings, other than ordinary routine litigation incidental to the Company's business, against the Company or its subsidiaries or of which any of their property is the subject, which, if determined adversely, would have a material adverse effect on the business or financial condition of the Company.

Item 1A. Risk Factors.

There have been no material changes from the risk factors set forth in Part I, Item 1A. “Risk Factors” of our Annual Report on Form 10-K for the period ended December 31, 2014. Please refer to that section of our Form 10-K for disclosures regarding the risks and uncertainties related to our business.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Issuer Purchases of Equity Securities

We did not repurchase any of our equity securities during the second quarter of 2015.

On July 17, 2014, the board of directors of the Company approved a new share repurchase program, allowing for the repurchase of up to $5.0 million of stock through December 31, 2016. The new repurchase program replaced the Company's prior repurchase program, pursuant to which the Company had repurchased approximately $3.7 million of common stock since January 1, 2013. 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. Of the $5.0 million of stock authorized under the repurchase plan, $3.8 million remained available for possible future repurchases as of June 30, 2015.

Unregistered Sales of Equity Securities

As previously disclosed on a Current Report on Form 8-K filed on May 1, 2015, in connection with the Central merger, the Company issued 2,723,083 shares of its common stock. As previously disclosed on a Current Report on Form 8-K filed on June 23, 2015, on June 22, 2015 the Company entered into a Securities Purchase Agreement with certain institutional accredited investors, pursuant to which, on June 23, 2015, the Company sold an aggregate of 300,000 newly issued shares of the Company’s common stock, $1.00 par value per share, at a purchase price of $28.00 per share for an aggregate amount of gross proceeds of $8.4 million. Each of the purchasers was an existing shareholder of the Company. The shares were issued and sold by the Company in each case in reliance upon an exemption from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended, and Rule 506(b) of Regulation D thereunder.

Item 3. Defaults Upon Senior Securities.
