MidWestOne Financial Group, Inc. and Subsidiaries
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, as amended, 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.
The Company owns all of the common stock of MidWestOne Bank, an Iowa state non-member bank chartered in 1934 with its main office in Iowa City, Iowa (the “Bank”), and all of the common stock of MidWestOne Insurance Services, Inc., Oskaloosa, Iowa. We operate primarily through our bank subsidiary, MidWestOne Bank, our bank subsidiary, 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.
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. On April 1, 2016, Central Bank merged with and into MidWestOne Bank.
The Company issued 2,723,083 shares of common stock and paid $64.0 million in cash, for total consideration of $141.9 million, in connection with the holding company merger. The results of operations acquired from Central have been included in the Company’s results of operations for the time period since the date of acquisition.
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 Principlesgenerally 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, 20152016 and for the year then ended. Management believes that the disclosures in this Form 10-Q 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 SeptemberJune 30, 20162017, and the results of operations and cash flows for the three and ninesix months ended SeptemberJune 30, 20162017 and 20152016. 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 ninesix months ended SeptemberJune 30, 20162017 may not be indicative of results for the year ending December 31, 2016,2017, or for any other period.
The Company adopted ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting," on January 1, 2017. The Company elected to account for forfeitures when they occur and recognize them in compensation cost at that time. There was no effect due to this accounting policy election on the Company’s consolidated financial statements.
The Company adopted ASU 2017-08, “Premium Amortization on Purchased Callable Debt Securities” during the second quarter of 2017. Since the Company was already amortizing premiums on callable investment securities between the date of purchase and the first call date, there was no cumulative effect adjustment necessary to the Company’s consolidated financial statements.
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, 20152016.
In the consolidated statements of cash flows, cash and cash equivalents include cash and due from banks, interest-bearing deposits in banks, and federal funds sold.
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 all 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 provided the Company with the opportunity to expand its 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.

This business combination was accounted for under the acquisition method of accounting. Accordingly, the results of operations of Central 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 $64.7 million has been recorded on the acquisition. Goodwill recorded in this transaction reflects the entry into the geographically new markets served by Central. Goodwill recorded in the transaction is not tax deductible. The amounts recognized for the business combination in the financial statements have been determined to be final as of March 31, 2016.
Estimated fair values of assets acquired and liabilities assumed in the Central transaction, as of the closing date of the transaction, were as follows:
 (in thousands) May 1, 2015
 ASSETS  
 Cash and due from banks $28,404
 Investment securities 160,775
 Loans 916,973
 Premises and equipment 27,908
 Goodwill 64,654
 Core deposit intangible 12,773
 Trade name intangible 1,380
 FDIC indemnification asset 3,753
 Other real estate owned 8,420
 Other assets 14,482
 Total assets 1,239,522
 LIABILITIES  
 Deposits 1,049,167
 Short-term borrowings 16,124
 Junior subordinated notes issued to capital trusts 8,050
 Subordinated notes payable 12,669
 Accrued expenses and other liabilities 11,617
 Total liabilities 1,097,627
 Total identifiable net assets 141,895
    
 Consideration:  
 Market value of common stock at $29.31 per share at May 1, 2015 (2,723,083 shares of common stock issued), net of stock illiquidity discount due to restrictions 77,895
 Cash paid 64,000
 Total fair value of consideration $141,895
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.
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 discount(1)
 (1,882) (16,670)
 Fair value of acquired loans $28,329
 $888,644
(1) Included in the accretable discount for purchased non-credit impaired loans is approximately $10.4 million of estimated undiscounted principal losses.
Disclosures required by ASC 805-20-50-1(a) concerning the Federal Deposit Insurance Corporation (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.
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 $0.2 million and $0.2 million in pretax merger-related expenses for the three months ended September 30, 2016 and 2015, respectively, and $4.2 million and $3.4 million for the nine months ended September 30, 2016 and 2015, respectively. For the three months ended September 30, 2016 these expenses included data processing fees of $0.1 million. This amount is included in data processing fees in the Company’s consolidated statements of operations. For the three months ended September 30, 2015, the expenses included professional and legal fees of $0.2 million. This amount is included in professional fees in the Company’s consolidated statements of operations. For the nine months ended September 30, 2016 and 2015, respectively, merger-related expenses included $0.3 million and $1.9 million of professional and legal fees, $1.7 million and $0.5 million of retention and severance compensation costs, and $1.9 million of data processing service contract termination costs for the nine months ended September 30, 2016, which are included in data processing expense.
The following table provides the unaudited pro forma information for the results of operations for the three and nine months ended September 30, 2015, as if the acquisition had occurred January 1, 2015. 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, 2015. No assumptions have been applied to the pro forma results of operations regarding possible revenue enhancements, expense efficiencies or asset dispositions. Net income in the table below includes merger expenses.
    Pro Forma
    Three Months Ended September 30, Nine Months Ended September 30,
     
 (in thousands)  2015 2015
 Total revenues (net interest income plus noninterest income)  $31,258
 $95,175
 Net income  $6,455
 $17,052
The pro forma information above excludes the impact of any provision recorded related to renewing Central loans.

Revenues and earnings of the acquired company for the current period have not been disclosed as it is not practicable because Central Bank was merged into MidWestOne Bank on April 1, 2016, and separate financial information is not readily available.

3.    Shareholders’ Equity
Preferred Stock: The number of authorized shares of preferred stock for the Company is 500,000. As of SeptemberJune 30, 20162017, none were issued or outstanding.

Of the $5.0 million of stock authorized under the repurchase plan, $5.0 million remained available for possible future repurchases as of SeptemberJune 30, 2016.2017.

4.3.    Earnings per 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.
The following table presents the computation of earnings per common share for the respective periods:

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 and the current and anticipated market conditions.
At SeptemberJune 30, 20162017 and December 31, 2015,2016, 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, the Federal National Mortgage Association, and the Government National Mortgage Association. 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 and collateralized mortgage obligations do not expose the Company to credit-related losses.
At SeptemberJune 30, 2016,2017, approximately 58%56% of the municipal bonds held by the Company were Iowa-based, and approximately 21% were Minnesota-based. The Company does not intend to sell these municipal obligations, and it is more likely than not that the Company will not be required to sell them until the recovery of 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 in fair value, as well as the evaluation of the fundamentals of the issuers’ financial conditions and other objective evidence, the Company believesbelieved that the municipal obligations identified in the tables above were temporarily impaired as of SeptemberJune 30, 20162017 and December 31, 2015.2016.
At SeptemberJune 30, 20162017 and December 31, 2015,2016, all but one of the Company’s corporate bonds held an investment grade rating from Moody’s, S&P or Kroll, or carried a guarantee from an agency of the US government. We have evaluated  financial statements of the company issuing the non-investment grade bond and found the company’s earnings and equity position to be satisfactory and in line with industry norms. Therefore, we believe the low market value of this investment is temporary and expect to receive all contractual payments. The internal evaluation of the non-investment grade bond along with the investment grade ratings on the remainder of the corporate portfolio lead us to conclude that all of the corporate bonds in our portfolio will continue to pay according to their contractual terms. Since the Company has the ability and intent to hold securities until price recovery, we believe that there is no other-than-temporary-impairment of in the corporate bond portfolio.
As of SeptemberJune 30, 2016,2017, the Company also owned $0.3$0.4 million of equity securities in banks and financial service-related companies, and $1.0$2.0 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 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 ninesix months ended SeptemberJune 30, 20162017 and the full year of 2015,2016, 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.
During the first quarter of 2017 as part of the Company’s annual review and analysis of municipal investments, $1.2 million of municipal bonds from a single issuer in the held to maturity portfolio, which did not carry a credit rating from one of the major statistical rating agencies, were identified as having an elevated level of credit risk. While the instruments were currently making payments as agreed, certain financial trends were identified that provided material doubt as to the ability of the entity to continue to service the debt in the future. The investment securities were classified as “watch,” and the Company’s asset and liability management committee were notified of the situation. In early March 2017 the Company learned of a potential buyer for the investments and a bid to purchase was received and accepted. Investment securities designated as held to maturity may generally not be sold without calling into question the Company’s stated intention to hold other debt securities to maturity in the future (“tainting”), unless certain conditions are met that provide for an exception to accounting policy. One of these exceptions, as outlined under Accounting Standards Codification (“ASC”) 320-10-25-6(a), allows for the sale of an investment that is classified as held to maturity due to significant deterioration of the issuer’s creditworthiness. Since the bonds had been internally classified as “watch” due to credit deterioration, the Company believes that the sale was in accordance with the allowable provisions of ASC 320-10-25-6(a), and as such, does not “taint” the remainder of the held to maturity portfolio. A small gain was realized on the sale.
It is reasonably possible that the fair values of the Company’s investment securities could decline in the future if interest rates increase or the overall economy or the financial conditions of the issuers deteriorate. As a result, there is a risk that 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 SeptemberJune 30, 20162017, is summarized as follows:

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.

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, a decline in the U.S. economy could harm or continue to harm the businesses of the Company’s commercial and industrial customers and reduce the value of the collateral securing these loans.
Commercial Real Estate - The Company offers mortgage loans to commercial and agricultural customers for the acquisition of real estate used in their 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.
Purchased Loans Policy
All purchased loans (nonimpaired and impaired) are initially measured at fair value as of the acquisition date in accordance with applicable authoritative accounting guidance. Credit discounts are included in the determination of fair value. An allowance for loan losses is not recorded at the acquisition date for loans purchased.

Individual loans acquired through the completion of a transfer, including loans that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable, are referred to herein as “purchased credit impaired loans.” In determining the acquisition date fair value and estimated credit losses of purchased credit impaired loans, and in subsequent accounting, the Company accounts for loans individually. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized as a yield adjustment or as a loss accrual or valuation allowance. Expected cash flows at the purchase date in excess of the fair value of loans, if any, are recorded as interest income over the expected life of the loans if the timing and amount of future cash flows are reasonably estimable. Subsequent to the purchasedpurchase 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 loan losses and a provision for loan losses. If the Company does not have the information necessary to reasonably estimate cash flows to be expected, it may use the cost-recovery method or cash-basis method of income recognition.

Charge-off Policy
The Company requires a loan to be charged-off, in whole or in part, 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 Company'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 Company'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 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 inexactness. Given the inherently imprecise nature of calculating the necessary ALLL, the Company’s policy permits the actual ALLL to be between 20% above and 5% below the “indicated reserve.”
As part of the merger between MidWestOne Bank and Central Bank, management developed a single methodology for determining the amount of the ALLL that would be needed at the combined bank. The new methodology is a hybrid of the methods used at MidWestOne Bank and Central Bank prior to the bank merger, and the results from the new ALLL model are consistent with the results that the two banks calculated individually. The refined allowance calculation allocates the portion of allowance that was previously deemed to be unallocated to instead be included in management’s determination of appropriate qualitative factors. These qualitative factors include (i) national and local economic conditions, (ii) the quality and experience of lending staff and management, (iii) changes in lending policies and procedures, (iv) changes in volume and severity of past due loans, classified loans and non-performing loans, (v) potential impact of any concentrations of credit, (vi) changes in the nature and terms of loans such as growth rates and utilization rates, (vii) changes in the value of underlying collateral for collateral-dependent loans, considering the Company’s disposition bias, and (viii) the effect of other external factors such as the legal and regulatory environment. The Company may also consider other qualitative factors for additional allowance allocations, including changes in the Company’s loan review process. Changes in the criteria used in this evaluation or the availability of new information could cause the allowance to be increased or decreased in future periods. In addition, bank regulatory agencies, as part of their examination process, may require adjustments to the allowance for loan losses based on their judgments and estimates.
Loans Reviewed Individually for Impairment
The Company identifies loans to be reviewed and evaluated individually for impairment based on current information and events and the probability that the borrower will be unable to repay all amounts due according to the contractual terms of the loan agreement. Specific areas of consideration include: size of credit exposure, risk rating, delinquency, nonaccrual status, and loan classification.
The level of individual impairment is measured using one of the following methods: (1) the fair value of the collateral less costs to sell; (2) the present value of expected future cash flows, discounted at the loan's effective interest rate; or

(3) the loan's observable market price. Loans that are deemed fully collateralized or have been charged down to a level corresponding with any of the three measurements require no assignment of reserves from the ALLL.
A loan modification is a change in an existing loan contract that has been agreed to by the borrower and the Bank, which may or may not be a troubled debt restructure or “TDR.” All loans deemed 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. Both financial distress on the part of the borrower and the Bank’s granting of a concession, which are detailed further below, must be present in order for the loan to be considered a TDR.
All of the following factors are indicators that the debtor is experiencing financial difficulties (one or more items may be present):
The debtor is currently in default on any of its debt.
The debtor has declared or is in the process of declaring bankruptcy.
There is significant doubt as to whether the debtor will continue to be a going concern.
Currently, the debtor has securities being held as collateral that have been delisted, are in the process of being delisted, or are under threat of being delisted from an exchange.
Based on estimates and projections that only encompass the current business capabilities, the debtor forecasts that its entity-specific cash flows will be insufficient to service the debt (both interest and principal) in accordance with the contractual terms of the existing agreement through maturity.
Absent the current modification, the debtor cannot obtain funds from sources other than the existing creditors at an effective interest rate equal to the current market interest rate for similar debt for a non-troubled debtor.

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 will be separated into homogeneous pools to be collectively evaluated. Loans will be first grouped into the various loan types (i.e. commercial, agricultural, consumer, etc.) and further segmented within each subset by risk classification (i.e. pass, special mention/watch, and substandard). Homogeneous loans past due 60-89 days and 90 days and over are classified special mention/watch and substandard, respectively, for allocation purposes.
The Company’s historical loss experience for each group segmented by loan type is calculated for the prior 20 quarters as a starting point for estimating losses. In addition, other prevailing qualitative or environmental factors likely to cause probable losses to vary from historical data are incorporated in the form of adjustments to increase or decrease the loss

rate applied to each group. These adjustments are documented and fully explain how the current information, events, circumstances, and conditions impact the historical loss measurement assumptions.
Although not a comprehensive list, the following are considered key factors and are evaluated with each calculation of the ALLL to determine if adjustments to historical loss rates are warranted:
Changes in national 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 quality and experience of lending staff and management.
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 the volume and severity of past due loans, classified loans and non-performing loans.
The existence and potential impact of any concentrations of credit.
Changes in the nature and terms of loans such as growth rates and utilization rates.
Changes in the value of underlying collateral for collateral-dependent loans, considering the Company’s disposition bias.
The effect of other external factors such as the legal and regulatory environment.
The Company may also consider other qualitative factors for additional allowance allocations, including changes in the Company’s loan review process. Changes in the criteria used in this evaluation or the availability of new information could cause the allowance to be increased or decreased in future periods. In addition, bank regulatory agencies, as part of their examination process, may require adjustments to the allowance for loan losses based on their judgments and estimates.
The items listed above are used to determine the pass percentage for loans evaluated under ASC 450, and as such, are applied to the loans risk rated pass. Due to the inherent risks associated with special mention/watch risk ratedrisk-rated loans (i.e. early stages of financial deterioration, technical exceptions, etc.), this subset is reserved at a level that will cover losses above a pass allocation for loans that had a loss in the last 20 quarters in which the loan was risk ratedrisk-rated special mention/watch at the time of the loss. Substandard loans carry greater risk than special mention/watch loans, and as such, this subset is reserved at a level that will cover losses above a pass allocation for loans that had a loss in the last 20 quarters in which the loan was risk ratedrisk-rated substandard at the time of the loss. Ongoing analysis will be performed to support these factor multiples.

The following tables set forth the risk category of loans by class of loans and credit quality indicator based on the most recent analysis performed, as of SeptemberJune 30, 20162017 and December 31, 2015:2016:

(1) As of the first quarter of 2017, the Company no longer considered credit cards a separate class of loans, and these balances are now included in commercial and industrial loans.
Included within the special mention/watch, substandard, and doubtful categories at SeptemberJune 30, 20162017 and December 31, 20152016 are purchased credit impaired loans totaling $16.8$13.9 million and $23.7$15.3 million, respectively.
Below are descriptions of the risk classifications of our loan portfolio.
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 as doubtful have all the weaknesses inherent in those classified as 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 as 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.

The following table presents loans individually evaluated for impairment, excluding purchased credit impaired loans, by class of loan, as of SeptemberJune 30, 20162017 and December 31, 2015:2016:

(1) As of the first quarter of 2017, the Company no longer considered credit cards a separate class of loans, and these balances are now included in commercial and industrial loans.
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.

Once a TDR has gone 90 days or more past due or is placed on nonaccrual status, it is included in the 90 days or more past due or nonaccrual totals.
The following table sets forth the composition of the Company’s recorded investment in loans on nonaccrual status and past due 90 days or more and still accruing by class of loans, excluding purchased credit impaired loans, as of SeptemberJune 30, 20162017 and December 31, 2015:2016:

Not included in the loans above as of SeptemberJune 30, 20162017 and December 31, 20152016 were purchased credit impaired loans with an outstanding balance of $2.8$0.4 million and $4.1$2.6 million, net of a discount of $0.9$0.1 million and $1.4$0.5 million, respectively.
As of SeptemberJune 30, 2016,2017, 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 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.
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.
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 former 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.

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 ninesix months ended SeptemberJune 30, 20162017 and 2015:2016:

7.6.    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 and the non-amortizing portion of the trade name intangible are subject to at least annual assessments for impairment by applying a fair value based test. The Company reviews goodwill and the non-amortizing portion of the trade name intangible at the reporting unit level to determine potential impairment annually on October 1, or more frequently if events or changes in circumstances indicate that the carrying value may not be recoverable, by comparing the carrying value of the reporting unit with the fair value of the reporting unit. No impairment was recorded on either the goodwill or the trade name intangible assets during the ninesix months ended SeptemberJune 30, 2016.2017. The carrying amount of goodwill was $64.7 million at SeptemberJune 30, 2016 and $64.6 million2017, the same as at December 31, 2015. The increase of $0.1 million in goodwill was due to the finalization of merger accounting issues related to the Central merger.
In addition to goodwill, the Company recognized a $12.7 million core deposit intangible, and a $1.4 million trade name intangible in 2015 due to the Central merger.2016.
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 and for the ninesix months ended SeptemberJune 30, 2016:2017:

The Bank is a member of the FHLB of Des Moines, and ownership of FHLB stock is a requirement for such membership. The amount of FHLB stock the Bank is required to hold is directly related to the amount of FHLB advances borrowed. Because this security is not readily marketable and there are no available market values, this security is carried at cost and evaluated for potential impairment each quarter. Redemption of this investment is at the option of the FHLB. No impairment was recorded on FHLB stock in the ninesix months ended SeptemberJune 30, 20162017 or in the year ended December 31, 2015.2016.
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 recorded within other assets on the balance sheet. On July 14, 2017, the Bank, entered into an agreement with the FDIC that terminated all of the Bank's loss sharing agreements related to the former Central Bank. See Note 15. “Subsequent Events” to our consolidated financial statements for additional information related to our termination of the loss-share agreements.
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.

9.8.    Short-Term Borrowings
Short-term borrowings were as follows as of SeptemberJune 30, 20162017 and December 31, 2015:2016:

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 plus 2.00%. The line was renewed in April 2016,May 2017, and is now scheduled to mature on April 27, 2017.28, 2018. The Company had no balance outstanding under this agreement as of SeptemberJune 30, 2016.2017.

(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 junior subordinated 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.

11.10.    Long-Term Borrowings

The Company utilizes FHLB borrowings as a supplement to customer deposits to fund earninginterest-earning assets and to assist in managing interest rate risk. As a member of the Federal Home Loan Bank of Des Moines, the Bank may borrow funds from the FHLB in amounts up to 35% of the Bank’s total assets, provided the Bank is able to pledge an adequate amount of qualified assets to secure the borrowings. Advances from the FHLB are collateralized primarily by one- to four-family residential, commercial and agricultural real estate first mortgages equal to various percentages of the total outstanding notes. See Note 65 “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. The Company drew $25.0 million on the note prior to June 30, 2015, at which time the

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, mortgage-backed securities, and mortgage-backedcollateralized mortgage obligations are priced utilizing industry-standard models that consider various assumptions, including time value, yield curves, volatility factors, prepayment speeds, default rates, loss severity, current market and contractual prices for the underlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace and are classified as Level 2. Municipal securities are valued using a type of matrix, or grid, pricing in which securities are benchmarked against the treasury rate based on credit rating. These model and matrix measurements are classified as Level 2 in the fair value hierarchy. On an annual basis, a group of selected municipal securities are pricedhave their credit rating evaluated by a securities dealer and that priceinformation is used to verify the primary independent service’s valuation.rating and pricing.
The following table summarizes assets measured at fair value on a recurring basis as of SeptemberJune 30, 20162017 and December 31, 2015.2016. There were no liabilities subject to fair value measurement as of these dates. The assets are segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value:

There were no transfers of assets between levels of the fair value hierarchy during the three and ninesix months ended SeptemberJune 30, 20162017 or the year ended December 31, 2015.2016.

There have been no changes in valuation techniques used for any assets measured at fair value during the three and ninesix months ended SeptemberJune 30, 20162017 or the year ended December 31, 2015.2016.
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 table discloses the Company’s estimated fair value amounts of its assets recorded at fair value on a nonrecurring basis. It is management’s belief that the fair values presented below are reasonable based on the valuation techniques and data available to the Company as of SeptemberJune 30, 20162017 and December 31, 20152016, as more fully described above.

 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.
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 non-interest bearing demand deposits, savings accounts and certain interest-bearing checking 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.
FHLB borrowings, junior subordinated notes issued to capital trusts, 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.

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.

14.13.    Operating Segments
The Company’s activities are considered to be a single industry segment for financial reporting purposes. The Company is engaged in the business of commercial and retail banking, investment management and insurance services with operations throughout central and eastern Iowa, the Twin Cities area of Minnesota and Wisconsin, Florida, and Florida.Denver, Colorado. Substantially all income is derived from a diverse base of commercial, mortgage and retail lending activities, and investments.

16.14.    Effect of New Financial Accounting Standards
In May 2014, the FASBFinancial Accounting Standards Board (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. In July 2015, the FASB announced a delay to the effective date of Accounting Standards Update No. 2015-09, 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 adoptionCompany’s revenue is comprised of interest income on financial assets, which is excluded from the scope of this amendmentnew guidance, and noninterest income. The Company expects this new guidance will potentially require it to change how certain recurring revenue streams are recognized within trust and asset management fees, sales of other real estate, credit and debit card interchange fees, and credit card revenue. In addition, the Company continues to stay apprised of certain issues related to implementation of the standard that are relevant to the banking industry which are still pending resolution. The Company is beginning to analyze the expected areas of impact, and currently does not expected to have a materialexpect the effect on the Company’s consolidated financial statements.statements to be material. The Company has determined that it will not early-adopt this standard, and plans to utilize the modified retrospective transition method.

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 isdid 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. 2015-09, 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.

In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance in this update makes changes to the current GAAP model primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged. The treatment of gains and losses for all equity securities, including those without a readily determinable market value, is expected to result in additional volatility in the income statement, with the loss of mark to market via equity for these investments. Additionally, changes in the allowable method for determining the fair value of financial instruments in the financial statement footnotes (“exit price” only), will likely require changes to current methodologies of determining these vales, and how they are disclosed in the financial statement footnotes. The new standard applies to public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. The adoptionCompany is in the process of evaluating the impact of this amendment is not expectedASU on its consolidated financial statements, including potential changes to have a material effect on the Company’s consolidatednote disclosure of the fair value of its financial statements.assets and liabilities, and does not expect to early adopt the standard.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842). The guidance in this update is meant to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. All leases create an asset and a liability for the lessee in accordance with FASB Concepts Statement No. 6, Elements of Financial Statements, and, therefore, recognition of those lease assets and lease liabilities represents an improvement over previous GAAP, which did not require lease assets and lease liabilities to be recognized for most leases. Disclosures are required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. To meet that objective, qualitative disclosures along with specific quantitative disclosures are required. The new standard applies to public business entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The Company is still evaluatinghas several lease agreements, such as branch locations, which are currently considered operating leases, and therefore not recognized on the effectCompany’s consolidated balance sheets. The Company expects the new guidance will require these lease agreements to now be recognized on the consolidated balance sheets as right-of-use assets and a corresponding lease liability. However, the Company continues to evaluate the extent of thisthe potential impact the new guidance will have on the Company’s consolidated financial statements.statements and the availability of outside vendor products to assist in the implementation, and does not expect to early adopt the standard.

In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718). The guidance involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The new standard applies to public business entities for annual periods beginning after December 15, 2016, including interim periods within those annual periods, with early adoption permitted. An entity that elects early adoption must adopt all of the amendments in the same period. The amendments were effective January 1, 2017. The Company is still evaluating theelected to account for forfeitures as they occur. The effect of this guidanceelection and other amendments did not have an effect on the Company’s consolidated financial statements.

In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments-Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model
for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The amendment requires the use of a new model covering current expected credit losses (CECL), which will apply to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance sheet credit exposures. Upon initial recognition of the exposure, the CECL model requires an entity to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses (ECL) should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments. The new guidance also amends the current available for sale (AFS) security OTTI model for debt securities. The new model will require an estimate of ECL only when the fair value is below the amortized cost of the asset. The length of time the fair value of an AFS debt security has been below the amortized cost will no

longer impact the determination of whether a credit loss exists. As such, it is no longer an other-than-temporary model. Finally, the purchased financial assets with credit deterioration (PCD) model applies to purchased financial assets (measured at amortized cost or AFS) that have experienced more than insignificant credit deterioration since origination. This represents a change from the scope of what are considered purchased credit-impaired assets under today’s model.

Different than the accounting for originated or purchased assets that do not qualify as PCD, the initial estimate of expected credit losses for a PCD would be recognized through an allowance for loan and lease losses with an offset to the cost basis of the related financial asset at acquisition. The new standard applies to public business entities that are SEC filers in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 31, 2018, including interim periods within those fiscal years.years, and is expected to increase the allowance for loan losses upon adoption.

In August 2016,January 2017, the FASB issued Accounting Standards Update No. 2016-15,2017-04, Statement of Cash FlowsIntangibles-Goodwill and Other (Topic 230)350) - Classification of Certain Cash Receipts and Cash Payments, a consensus ofSimplifying the FASB Emerging Issues Task ForceTest for Goodwill Impairment.. The new guidance addresses diversity in practice in how certain cash receipts and cash payments are presented and classified inremoves Step 2 of the statementgoodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of cash flows under Topic 230, Statement of Cash Flows, andgoodwill. All other topics. Thisgoodwill impairment guidance will remain largely unchanged. The update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments in this update applyapplies to all entities, including bothpublic business entities and not-for-profit entities that are requiredSEC filers in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company early adopted this amendment during the second quarter of 2017, and adoption did not have a significant effect on the Company’s consolidated financial statements.

In March 2017, the FASB issued Accounting Standards Update No. 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities. The new guidance requires that the premium amortization period on non-contingently callable securities, end at the earliest call date, rather than the contractual maturity date. The shorter amortization period means that interest income would generally be lower in the periods before the earliest call date and higher thereafter (if the security is not called) compared to present a statement of cash flows under Topic 230.current GAAP. The update applies to public business entities in fiscal years beginning after December 15, 2017, including2018. Early adoption is permitted. If an entity early adopts the amendments in an interim periods within thoseperiod, any adjustments should be reflected as of the beginning of the fiscal years, with early adoption permitted,year that includes that interim period. The Company adopted this update during the second quarter of 2017. Since the Company was already amortizing premiums on callable investment securities between the date of purchase and the Company has elected to adoptfirst call date, there was no effect on the guidance effective September 30, 2016.Company’s consolidated financial statements.

17.    Contingency
In the second quarter of 2012, the Bank, terminated its non-contributory defined benefit pension plan. In the normal course of business, the termination of the plan is subject to audit by the Pension Benefit Guaranty Corporation (PBGC), which may result in additional distribution of assets to participants. The Bank has received an initial summary of audit findings and is requesting reconsideration of this initial determination.  In addition, the Bank has identified a potential inadvertent drafting issue with the wording of the plan amendment adopted by the Bank in 2005.The Bank has evaluated the likelihood of a potential future liability relating to this amendment issue and determined that while future liability is possible, the amount of the liability cannot be reasonably estimated at this time. As such, no liability relating to this matter has been recorded in the financial statements for the third quarter of 2016.

18.15.    Subsequent Events
Management evaluated subsequent events through the date the consolidated financial statements were issued. Events or transactions occurring after SeptemberJune 30, 20162017, but prior to the date the consolidated financial statements were issued, that provided additional evidence about conditions that existed at SeptemberJune 30, 20162017 have been recognized in the consolidated financial statements for the three and ninesix months ended SeptemberJune 30, 20162017. Events or transactions that provided evidence about conditions that did not exist at SeptemberJune 30, 20162017, but arose before the consolidated financial statements were issued, have not been recognized in the consolidated financial statements for the three and ninesix months ended SeptemberJune 30, 20162017.
On October 11, 2016July 14, 2017, the board of directors of the Company declared a cash dividend of $0.160.17 per share payable on DecemberSeptember 15, 20162017 to shareholders of record as of the close of business on DecemberSeptember 1, 20162017.
On July 14, 2017, MidWestOne Bank (the “Bank”), entered into an agreement with the Federal Deposit Insurance Corporation (FDIC) that terminated all of the Bank's loss sharing agreements related to the former Central Bank's six FDIC-assisted acquisitions from 2009 through 2011.
The agreement required the Bank to pay $0.3 million to the FDIC to settle all outstanding items related to the terminated loss sharing agreements. As a result of entering into the agreement, assets that were covered by the terminated loss sharing agreements, including covered loans in the amount of $27.2 million on June 30, 2017, have been reclassified as non-covered assets, effective July 14, 2017.
Accordingly, in the third quarter of 2017, the Company expects to realize a one-time pre-tax gain of approximately $0.2 million, inclusive of the write-off of the remaining indemnification asset, other receivables from the FDIC and the Bank's clawback liabilities due to the FDIC. The termination of the loss sharing agreements will not impact the yields for the loans that were previously covered under this agreement and is not expected to impact the allowance for loan losses. All

future recoveries, gains, losses and expenses related to these previously covered assets will now be recognized entirely by the Bank since the FDIC will no longer be sharing in such gains or losses. Accordingly, the Company's future earnings will be positively impacted to the extent the Company recognizes gains on any sales or recoveries in excess of the carrying value of such assets. Similarly, the Company's future earnings will be negatively impacted to the extent the Company recognizes expenses, losses or charge-offs related to such assets.

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 Upperupper Midwest through its bank subsidiary, MidWestOne Bank. The Bank has office locations in central and east-central Iowa, the Twin Cities area of Minnesota, Wisconsin, Florida, and Florida.Denver, Colorado. The Bank is actively engaged in many areas of commercial banking, including: acceptance of demand, savings and time deposits; making commercial, real estate, agricultural and consumer loans; and other banking services tailored for its individual customers. The Wealth Management Division of MidWesttheOne Bank administers estates, personal trusts, conservatorships, and pension and profit-sharing accounts along with providing brokerage and other investment management services to customers. MidWestOne Insurance Services, Inc., also a wholly-owned subsidiary of the Company, provides personal and business insurance services in Iowa.
We operate as an independent community bank that offers a broad range of customer-focused financial services as an alternative to large regional banks in our market areas. Management has invested in infrastructure and staffing to support our strategy of serving the financial needs of businesses, individuals and municipalities in our market areas. 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 2015Annual Report on Form 10-K.10-K for the year ended December 31, 2016. Results of operations for the three and ninesix months ended SeptemberJune 30, 20162017 are not necessarily indicative of results to be attained for any other period.
Critical Accounting Policies
Critical accounting estimates are those which are both most important to the portrayal of our financial condition and results of operations, and require our management's most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Our critical accounting estimates relate to the allowance for loan losses, application of purchase accounting, goodwill and intangible assets, and fair value of available for sale investment securities, all of which involve significant judgment by our management. Information about our critical accounting estimates is included under Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2015.2016.

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.
Net interest income of $24.6$26.2 million for the thirdsecond quarter of 2017 increased $1.3 million, or 5.0%, from $24.9 million for the second quarter of 2016, decreased $2.2 million, or 8.1%, from $26.8 million for the third quarter of 2015, primarily due to a decreasean increase of $2.1$1.8 million, or 7.0%6.5%, in interest income. A decreaseAn increase in the merger-related discount accretion of $0.6 million, to $0.6$1.3 million for the thirdsecond quarter of 2017 compared to $0.7 million for the second quarter of 2016, compared to $1.7 million for the third quarter of 2015, and generally lower rates being received on new loans, partially offset by an increasea decrease in average loan balances, resulted in loan interest income declining $2.4increasing $1.0 million, or 8.8%4.1%, to $24.3$25.7 million for the thirdsecond quarter of 20162017 compared to the thirdsecond quarter of 2015.2016. Income from investment securities was $3.5$4.2 million for the thirdsecond quarter of 2016,2017, up from $3.3 million for the thirdsecond quarter of 2015,2016, which resulted from an increase of $19.3$134.5 million in the average balance, along with an increasepartially offset by a decrease of 610 basis points in the yield of investment securities between the two comparable periods.
Interest expense increased $0.1$0.6 million, or 2.5%18.2%, to $3.3$3.7 million for the thirdsecond quarter of 2016,2017, compared to $3.2$3.1 million for the same period in 2015,2016 primarily due to an increase in both the average balance and rate of FHLB borrowings. This increase was partially offset by decreases in the cost of interest on most other categories of interest-bearing liabilities. The decline in the cost of interest-bearing deposits was despite a decreaseof 9 basis points on increased average balances of $91.8 million between the second quarter of 2017 and the same period in the2016. The merger-related amortization of the purchase accounting premium on certificates of deposit, which acts to reduce interest expense, declined from $0.4$0.3 million for the thirdsecond quarter of 2015,2016, to $0.2 millionzero for the same period of 2016. Amortization2017. Additionally, the average balance of Federal Home Loan Bank (“FHLB”) borrowings decreased, partially offset by an increase in the purchase accounting premium on certificatesaverage rate paid, resulting in $0.1 million of deposit acts to decrease deposit interest expense.reduced expense between the comparable periods.
Our net interest margin for the second quarter of 2017, calculated on a fully tax-equivalent basis, for the third quarter of 2016 declined to 3.72% compared withwas 3.91%, or 8 basis points higher than the net interest margin of 4.14%3.83% for the thirdsecond quarter of 2015. Net interest margin is a measure of the net return on earning assets and is computed by dividing annualized net interest income on a tax-equivalent basis by the average of total earning assets for the period. Our overall yield on earning assets decreased to 4.20% for the third quarter of 2016 from 4.62% for the third quarter of 2015. This decline was due primarily to a lower2016. A higher yield received on loans, and the effect of lower merger-relatedcombined with higher discount accretion resulted in a 19 basis point increase in overall loan yield. This increase was partially offset by a 10 basis point decrease in the thirdyield on investment securities, resulting in higher yield on interest-earning assets for the second quarter of 2016 compare2017 compared to the thirdsecond quarter of 2015.2016. The cost of deposits increased 9 basis points, due primarily to the absence of purchase premium amortization in 2017, while the average cost of interest-bearing liabilities was the same in the third quarter of 2016, at 0.61%, as for the third quarter of 2015.borrowings edged higher by 6 basis points.

The following table shows consolidated average balance sheets, detailing the major categories of assets and liabilities, the interest income earned on earning assets, the interest expense paid for interest-bearing liabilities, and the related yields and interest rates for the quarters ended SeptemberJune 30, 20162017 and 2015.2016. Dividing annualized income or expense by the average balances of assets or liabilities results in average yields or rates. Average information is provided on a daily average basis.

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 SeptemberJune 30, 2016,2017, compared to the same period in 2015,2016, 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 thirdsecond quarter of 2016 decreased $2.32017 increased $1.0 million, or 8.5%4.0%, compared with the same period in 2015.2016. This decreaseincrease includes the effect of the merger-related discount accretion of $0.6$1.3 million on loans for the thirdsecond quarter of 20162017 compared to $1.7$0.7 million of merger-related discount accretion for the thirdsecond quarter of 2015.2016. Average loans were $26.2$10.9 million, or 1.2%0.5%, higherlower in the thirdsecond quarter of 2017 compared with the second quarter of 2016, compared withprimarily resulting from loan payments and payoffs exceeding new loan demand early in the third quarter of 2015, due primarily to the origination of new loans (primarily commercial real estate and agricultural), and despite the loss of approximately $33.0 million of loans due to the sale of the Company’s Davenport, Iowa branch in early August 2016.second quarter. In addition to purchase accounting adjustments, 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. The decreaseincrease in interest income on loans was primarily the result of a decreaseincrease in the average yield on loans from 5.06%4.63% in the thirdsecond quarter of 20152016 to 4.58%4.82% in the thirdsecond quarter of 2016,2017, which was primarily attributable to purchase accounting adjustments and the general increase in interest rates, partially offset by the higherlower average balances in the loan portfolio.
Interest income on investment securities on a tax-equivalent basis totaled $4.2$5.0 million in the thirdsecond quarter of 20162017 compared with $4.0$4.1 million for the same period of 2015,2016, including $0.1 million of purchase accounting premium amortization expense in both the 2015 and 2016 periods. The tax-equivalent yield on our investment portfolio in the thirdsecond quarter of 2016 increased2017 decreased to 3.04%3.14% from 2.98%3.24% in the comparable period of 2015.2016. The average balance of investments in the thirdsecond quarter of 2017 was $641.1 million compared with $506.6 million in the second quarter of 2016, was $551.8 million compared with $532.5 million in the third quarter of 2015, an increase of $19.3$134.5 million, or 3.6%26.5%. The increase in average balance resulted primarily from deployingredeployment of excess cash availableheld in the second quarter of 2016 and the investment of the proceeds from the sale of newly issued common stock at the end of the priorfirst quarter into new investments.and beginning of the second quarter of 2017.
Interest expense on deposits was generally unchangedincreased $0.6 million, or 25.1%, to $2.8 million in the thirdsecond quarter of 20162017 compared with$2.3 million in the same period of 2016. The increased interest expense on deposits was primarily due to an increase of 9 basis points in the weighted average rate paid on interest-bearing deposits to 0.56% in the second quarter of 2017, compared with 0.47% in the second quarter of 2016. This includes the effect of no merger-related premium amortization on certificates of deposit for

the second quarter of 2017 compared with $0.3 million for the same period in 2015 at $2.5 million for both periods. While the Company experienced an2016. The premium amortization acted to decrease deposit interest expense. An increase in average balances of interest-bearing deposits for the thirdsecond quarter of 20162017 of $56.7$91.8 million compared with the same period in 2015, this increase was offset by the weighted average2016, also contributed to increased expense. We expect to see some upward movement in deposit rates in future periods, as overall interest rate paid on interest-bearing deposits decliningincreases begin to 0.51%take hold in the third quarter of 2016, compared with 0.52% in the third quarter of 2015. This decrease includes the effect of the merger-related premium amortization of $0.2 million on certificates of deposit

for the third quarter of 2016 compared with $0.4 million for the same period in 2015. The premium amortization acts to decrease deposit interest expense.our market footprint.
Interest expense on borrowed funds of $0.8 million in the thirdsecond quarter of 20162017 was an increase of $0.1 million, or 12.2%, compared with $0.7 million forunchanged from the same period in 2015.2016. Average borrowed funds for the thirdsecond quarter of 20162017 were $16.6$9.1 million higherlower compared with the same period in 2015. This increase was2016.

Theborrowing for the second quarter of 2017 compared to the same period in 2016 , was offset by an increase in the weighted average rate on borrowed funds increased to 1.52%1.62% for the thirdsecond quarter of 20162017 compared with 1.46%1.56% for the thirdsecond quarter of 2015,2016, primarily reflecting the increased cost of FHLB borrowings.all borrowing instruments.
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 the loan portfolio. 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, and historical loan loss experience. 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 $1.0$1.2 million in the thirdsecond quarter of 2016, a decrease2017, an increase of $1.1$0.1 million, from $2.1$1.1 million in the thirdsecond quarter of 2015. The higher provision expense in 2015 was primarily due to the greater volume of acquired loans coming out of purchase accounting and moving into the Company’s standard allowance for loan loss methodology.2016. Net loans charged off in the thirdsecond quarter of 20162017 totaled $0.8$0.9 million, compared to $0.4$0.2 million net loans charged off in the thirdsecond quarter of 2015.2016. 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 believed that the allowance for loan losses was adequate based on the inherent risk in the portfolio as of SeptemberJune 30, 2016;2017; 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 the 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.

This decrease was due to a decreased level of loans originated and sold on the secondary market in the second quarter of 2017 compared to a negligible gain for the thirdsecond quarter of 2015.2016, a result of the general decrease in mortgage activity in our markets. Other gain decreased $0.1 million, or 70.2%, between the second quarter of 2017 and the second quarter of 2016 comparable periods, due primarily to lower gains on the sale of other real estate owned. Other gain (loss) represents gains and losses on the

sale of branch banking offices, other real estate owned, repossessed assets, and branch banking offices. The third quarter of 2016 reflects a net gain on other real estate owned of $0.1 million, a write down of other real estate owned of $0.5 million, and a net gain on the sale of the Bank’s Davenport, Iowa branch of $0.7 million, while the third quarter of 2015 included a small net gain on other real estate owned.assets. These itemsdecreases were previously classified aspartially offset by increases in other service charges and fees, and have now been broken outwhich increased $0.1 million, or 8.6%, from $1.4 million in the second quarter of 2016 to provide additional transparency. Loan origination and servicing fees increased from $1.0$1.5 million for the thirdsecond quarter of 2015 to $1.22017, and a $0.1 million, for the third quarter

Net Interest Income
Our net interest income for the ninesix months ended SeptemberJune 30, 20162017, was $75.1$51.3 million, up $11.4$0.8 million, or 17.8%1.5%, from $63.7$50.5 million for the ninesix months ended SeptemberJune 30, 2015,2016, primarily due to an increase of $12.8$1.9 million, or 17.8%3.4%, in interest income. Loan interest income increased $13.1 million, or 21.5%, to $74.1 million for the first nine months of 2016 compared to the first nine months of 2015, primarily due to the merger-related increase in average loan balances of $305.0 million, or 16.4%, between the two periods, and despite the effect of a decrease in the merger-related discount accretion to $2.4 million for the nine months ended September 30, 2016, compared to $3.0 million for the nine months ended September 30, 2015. Interest income on investment securities increased $0.3rose $1.8 million, or 3.1%26.4%, to $10.2$8.5 million for the first ninesix months of 20162017 compared to the first ninesix months of 20152016 primarily due to an increase of 13 basis points on the portfolio’s yield, somewhat offset by a decrease of $7.4$127.3 million in the average balance between the comparative periods. There was noLoan interest income from loan pool participations in the first nine months of 2016 comparedincreased $0.2 million, or 0.4%, to $0.8 million of income in the first nine months of 2015, as the Company sold its remaining loan pool participations in June 2015.
Total interest expense was $9.3$49.9 million for the ninefirst six months ended September 30, 2016, an increase of $1.4 million, or 17.7%,2017 compared to the first ninesix months of 2015.2016, primarily due to the 6 basis point increase in average loan yield between the two periods, which included the effect of an increase in the discount accretion related to the merger of the Company with Central, to $2.5 million for the six months ended June 30, 2017, compared to $1.9 million for the six months ended June 30, 2016. The increased loan yield was partially offset by an $8.7 million, or 0.4%, decrease in the average balance of loans between the comparative periods. These income increases were partially offset by an increase of $1.1 million, or 18.6%, in interest expense, to $7.1 million for the six months ended June 30, 2017, compared to $6.0 million for the first six months of 2016. Interest expense on deposits increased $0.9$1.1 million, or 16.2%25.8%, to $6.8$5.5 million for the ninesix months ended SeptemberJune 30, 2017 compared to $4.3 million for the six months ended June 30, 2016, (including $0.8 million in merger-related amortization ofprimarily due to the purchase accounting premiuminterest expense on certificates of deposit), compared to $5.9 million (including $1.0 million in merger-related amortization)deposits for the ninesix months ended SeptemberJune 30, 2015.
Our net interest margin on a tax-equivalent basis for the first nine months of 2016 increased to 3.83% compared with the net interest margin of 3.69% for the first nine months of 2015. Net interest margin is a measure of the net return on earning assets and is computed by dividing annualized net interest income on a tax-equivalent basis by the average of total earning assets for the period. Our overall yield on earning assets was 4.29% for the first nine months of 2016, an increase of 16 basis points compared to the first nine months of 2015. This increase was despite the inclusion of $2.4 million of merger-related discount accretion income

for loans in the first nine months of 2016, compared to $3.0 million of discount for the first nine months of 2015. The average cost of interest-bearing liabilities increased in the first nine months of 2016 to 0.58% from 0.56% for the first nine months of 2015, due primarily to the higher cost of obtaining deposits during the period and increased rates on FHLB borrowings, despite the inclusion of $0.8 million of2017 including no merger-related amortization of the purchase accounting premium on certificates of deposit, and the interest expense on deposits for the six months ended June 30, 2016 including $0.7 million in merger-related amortization. Interest expense related to borrowings was essentially unchanged between the first nine monthstwo periods.
The Company posted a net interest margin of 2016, compared to $1.0 million of such amortization3.85% for the first ninesix months of 2015.2017, down 4 basis points from the net interest margin of 3.89% for the same period in 2016. The decrease was primarily due to a 27 basis point increase in the cost of certificates of deposit due primarily to the aforementioned decrease in deposit premium amortization, and was the primary factor in a 7 basis

point increase in the cost of interest-bearing liabilities. For the first six months of 2017 compared with the same period in 2016, a 6 basis point increase in loan yields and a higher volume of average investment securities, which generally have a lower yield compared to loans, resulted in a 3 basis point increase in the yield on earning assets.
The following table shows consolidated average balance sheets, detailing the major categories of assets and liabilities, the interest income earned on earninginterest-earning assets, the interest expense paid for interest-bearing liabilities, and the related yields and interest rates for the ninesix months ended SeptemberJune 30, 20162017 and 20152016. Dividing annualized income or expense by the average balances of assets or liabilities results in average yields or costs. Average information is provided on a daily average basis.

The following table sets forth an analysis of volume and rate changes in interest income and interest expense on our average earninginterest-earning assets and average interest-bearing liabilities during the ninesix months ended SeptemberJune 30, 2016,2017, compared to the same period in 20152016, 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 $13.3$0.1 million, or 21.5%0.3%, in the first ninesix months of 20162017 compared to the same period in 2015.2016. This increase reflects the effect of the merger-related discount accretion for loans of $2.4$2.5 million in the first ninesix months of 2016,2017, compared to $3.0$1.9 million of discount accretion in the first ninesix months of 2015.2016. The increased income is mainly due to ana 6 basis point increase in averageyield on loans, balances of $305.0 million, or 16.4%,from 4.67% in the first ninesix months of 2016 compared to the same period in 2015, primarily resulting from the merger. The yield on loans increased from 4.46% in the first nine months of 2015 to 4.65%4.73% in the same period of 2016.2017. 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 Average loan pool participations was nothing for the first nine months of 2016,balances experienced a decrease of $0.8$8.7 million, or 0.4%, in the first six months of 2017 compared to the first nine months of 2015. The Company sold its remainingsame period in 2016, primarily resulting from loan pool participationspayments and payoffs exceeding current period new loan demand.

Interest income on investment securities on a tax-equivalent basis totaled $12.4$10.1 million in the first ninesix months of 20162017 compared with $12.1$8.2 million for the same period of 2015,2016, reflecting $0.2$0.1 million of purchase accounting premium amortization expense in the first ninesix months of 20162017, compared to $0.2 million of purchase accounting premium amortization in the first ninesix months of 2015.2016. The tax-equivalent yield on our investment portfolio for the first ninesix months of 2016 increased2017 decreased to 3.12%3.15% from

Interest expense on deposits was $6.8$5.5 million for the first ninesix months of 20162017 compared with $5.9$4.3 million for the same period in 2015.2016. This increase was in partprimarily due to average interest-bearinginterest expense on deposits for the first ninesix months of 2016 increasing $211.5 million, or 12.4%, compared with the same period in 2015, due primarily to the merger.
The weighted average rate paid on interest-bearing deposits was 0.47% for the first nine months of 2016 compared with 0.46% for the first nine months of 2015. This increase reflects theended June 30, 2017 including no merger-related amortization of the purchase accounting premium on certificates of deposit and the six months ended June 30, 2016 interest on deposits including $0.7 million in merger-related amortization. Additionally, average interest-bearing deposits for the amountfirst six months of $0.82017 increased $108.6 million, or 5.7%, compared with the same period in 2016, due primarily to an

increased focus by the Company on gathering new deposits. The weighted average rate paid on interest-bearing deposits was 0.55% for the first six months of 2017 compared with 0.46% for the first six months of 2016. This increase reflects the effect of no merger-related amortization of the purchase accounting premium on certificates of deposit for the first six months of 2017 compared with $0.7 million for the first ninesix months of 2016 compared with $1.0 million for the first nine months of 2015.

Interest expense on borrowed funds in the first ninesix months of 20162017 was $2.5$1.7 million, compared with $2.1 million forunchanged from the same period in 2015.2016. Average borrowed funds for the first ninesix months of 20162017 were $33.8$8.6 million higherlower compared with the same period in 2015. 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 the $20.1 million increase2016. The decrease in the average level of FHLB borrowings of $6.2 million, or 5.8%, coupled with a $5.2 million, or 11.0%, decrease in long-term debt and junior subordinated notes, was partially offset by an increase in the average balance of federal funds purchased, repurchase agreements, and other short-term borrowings of $2.8 million, or 3.6%, all for the first ninesix months of 20162017 compared to the first ninesix months of 2015.2016.

The greatest increase2016. This decline was primarily due to the $1.3 million decrease in other gains for the ninesix months ended SeptemberJune 30, 2016, was in other gain (loss), which increased $1.8 million to a gain of $1.4 million for the nine months ended September 30, 2016,2017, compared to a loss of $0.4 million for the nine months ended September 30, 2015.same period in 2016.

Loan Review and Classification Process for Agricultural, Commercial and Industrial, and Commercial Real Estate Loans:
The Bank maintains a loan review and classification process which involves multiple officers of the 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. The 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 all lending relationships with total exposure of $5.0 million or more as well as all classified (loan grades 6 through 8) and Watchwatch (loan grade 5) rated credits over $1.0 million 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 watch (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 (loan grade 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 loan strategy committee. Copies of the minutes of these Committeecommittee meetings are presented to the board of directors of the Bank.
Depending upon the individual facts and circumstances and the result of the Classified/Watchclassified/watch review process, loan officers and/or loan review personnel may categorize the loan relationship as impaired. Once that determination has occurred, the credit analyst 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 calculation. Impairment analysis for the underlying collateral value is completed in the last month of the quarter.   The impairment analysis worksheets are reviewed by the Credit Administration department prior to quarter-end. The board of directors of the Bank on a quarterly basis reviews the Classified/Watchclassified/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. All requests for an upgrade of a credit are approved by the loan strategy committee before the rating can be changed.
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.
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 overor more past due or nonaccrual totals.
During the ninesix months ended SeptemberJune 30, 2016,2017, the Company restructured fiveten loans by granting concessions to borrowers 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 SeptemberJune 30, 20162017 and December 31, 20152016 is as follows:

Allowance for Loan Losses
Our ALLL as of SeptemberJune 30, 20162017 was $21.4$22.5 million, which was 1.00%1.02% of total loans and 1.30%1.20% of purchased non-credit impaired loans as of that date. This compares with an ALLL of $19.4$21.9 million as of December 31, 2015,2016, which was 0.90%1.01% of total loans and 1.32%1.27% of purchased non-credit impaired loans as of that date. Gross charge-offs for the first ninesix months of 20162017 totaled $1.7 million, while there was $0.1 million in recoveries of previously charged-off loans totaled $0.5 million.loans. The ratio of annualized net loan charge offs to average loans for the first ninesix months of 20162017 was 0.08%0.15% compared to 0.11%0.26% for the year ended December 31, 2015.2016. As of SeptemberJune 30, 2016,2017, the ALLL was 90.4%86.2% of nonperforming loans compared with 168.5%76.8% as of December 31, 2015.2016. Based on the inherent risk in the loan portfolio, wemanagement believed that as of SeptemberJune 30, 2016,2017, 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 maywill 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 2017. Classified and impaired loans are reviewed per the requirements of FASB ASC Topic 310.
Non-acquired loans with a balance of $1.61$1.79 billion at SeptemberJune 30, 2016,2017, had $20.9$21.5 million of the allowance for loan losses allocated to them, providing an allocated allowance for loan loss to non-acquired loan ratio of 1.30%.1.20%, compared to balances of $1.68 billion and an an allocated allowance for loan loss to non-acquired loan ratio of 1.27% at December 31, 2016. Non-acquired loans are total loans minus those loans acquired in the Central merger. New loans and loans renewed after the merger are considered non-acquired loans.

The Bank and Central Bank, management developeduses a single methodology for determining the amount of the ALLL that would be needed at the combined bank. The new methodology is a hybrid of the methods used at MidWestOne Bank and Central Bank prior to the bank merger, and the results from the new ALLL model are consistent with the results that the two banks calculated individually.
During the first quarter of 2016 we changed therolling 20-quarter annual average historical net charge-off component of thefor its ALLL calculation to include both Central Bank and MidWestcalculation. One Bank in the 20-quarter annual average. A separate qualitative factor table is now being maintainedused for each region MidWestOne Bank servicesthe entire bank. Differences in regional (Iowa, Minnesota/Wisconsin, Florida and Florida), all with a similar methodology, but adjusted based on the economic/Colorado) economic and business conditions are included in each region. Loans below $250,000 continue to be evaluated solelythe qualitative factor narrative and the risk is spread over the entire loan portfolios. All pass rated loans, regardless of size, are allocated based on delinquency status, but no longer receive an increased allocation of between 25% and 50% of the loss given default. Instead they receive the normal ASC 450 allocation based on the type of loan and the risk rating. To streamlinestatus. The Bank has streamlined the ALLL process

for a number of low-balance loan types that do not have a material impact on the overall calculation, which are now excluded. Asapplied a reserve amount equal to the overall reserve calculated pursuant to applicable accounting standards to total loan calculated pursuant to applicable accounting standards. The guaranteed portion of the first quarter 2016, overdrafts are no longerany government guaranteed loan is included in the ALLL calculation. Additionally, the guaranteed portion of government guaranteed loans is no longer being adjusted out of the calculation and as a result,is reserved for according to the entire loan balance is subject to reserve requirements.type of loan. Special mention/watch and substandard rated credits not individually reviewed for impairment previously received an allocation of 2 times and 6 times, respectively, of the pass allocation. Dueare allocated at a higher amount due to the inherent risks associated with specialthese types of loans. Special mention/watch risk rated loans (i.e. early stages of financial deterioration, technical exceptions, etc.), this subset is are reserved at a level that will cover losses above a pass allocation for loans that had a loss in the last 20 quarterstrailing 20-quarters in which the loan was risk ratedrisk-rated special mention/watch at the time of the loss. Substandard loans carry a greater risk than special mention/watch loans, and as such, this subset is reserved at a level that covers losses above a pass allocation for loans that had a loss in the last 20 quarterstrailing 20-quarters in which the loanloans was risk ratedrisk-rated substandard at the time of the loss. Classified and impaired loans are reviewed per the requirements of FASB ASC Topic 310.applicable accounting standards.
We currently track the loan to value (“LTV”) ratio of loans in our portfolio, and those loans in excess of internal and supervisory guidelines are presented to the Bank’s board of directors on a quarterly basis. At SeptemberJune 30, 2016,2017, there were 3132 owner-occupied 1-4 family loans with a LTV ratio of 100% or greater. In addition, there were 224178 home equity loans without credit enhancement that had a LTV ratio of 100% or greater. We have the first lien on 155 of these equity loans and other financial institutions have the first lien on the remaining 209.173. Additionally, there were 172196 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 SeptemberJune 30, 2016,2017, TDRs were not a material portion of the loan portfolio. We review loans 90 days or more 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. The Bank’s board of directors has reviewed these credit relationships and determined that these loans and the risks associated with them were acceptable and did not represent any undue risk.
Capital Resources
Total shareholders’ equity was $309.6$342.9 million as of SeptemberJune 30, 2016,2017, compared to $296.2$305.5 million as of December 31, 2015,2016, an increase of $13.4$37.4 million, or 4.5%12.2%. This increase was primarily attributable to the issuance of 750,000 shares of common stock in a public offering, resulting in $24.4 million of additional capital, net of expenses. Also contributing to the increase in capital was net income of $16.5$13.9 million for the first ninesix months of 2016,2017, a $1.8$2.6 million increase in accumulated other comprehensive income due to market value adjustments on investment securities available for sale, and a $0.6 million decrease in treasury stock due to the issuance of 27,06732,168 shares of Company common stock in connection with stock compensation plans. These increases were partially offset by the payment of $5.5$3.9 million in common stock dividends. No shares of Company common stock were repurchased in the thirdsecond quarter of 2016.
Total2017. The total shareholders’ equity was 10.31% ofto total assets as of Septemberratio was 11.09% at June 30, 2016 and was 9.94% of total assets as of2017, up from 9.92% at December 31, 2015.2016. The ratio of tangible equity to tangible assets ratio was 7.94% as of September8.86% at June 30, 2016 and 7.51% as of2017, compared with 7.62% at December 31, 2015. 2016. Tangible book value per share was $21.86 at June 30, 2017, an increase from $20.00 per share at December 31, 2016.
Our Tier 1 capital to risk-weighted assets ratio was 10.90%11.70% as of SeptemberJune 30, 20162017 and was 10.63%10.73% as of December 31, 2015.2016. 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. WeManagement believed that, as of SeptemberJune 30, 2016,2017, the Company and the Bank met all capital adequacy requirements to which we were subject. As of that date, the Bank was “well capitalized” under regulatory prompt corrective action provisions.
In July 2013,The Company and the U.S. federal banking agencies approved the implementation ofBank are subject to the Basel III regulatory capital reforms in pertinent part (the “Basel III Rules”), and at the same time, promulgated rules effecting certain changes required by the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”). In contrast to capital requirements historically, which were in the form of guidelines, Basel III was released in the form of regulations by each of the regulatory agencies. The Basel III Rules are applicable to all banking organizations that are subject to minimum capital requirements, including federal and state banks and savings and loan associations, as well as to bank and savings and loan holding companies, other than “small bank holding companies” (generally bank holding companies with consolidated assets of less than $1 billion which are not publicly traded companies). The Basel III Rules not only increased most of the required minimum regulatory capital ratios, but they also introduced a Common Equity Tier 1 capital ratio and the concept of a capital conservation buffer. The Basel III Rules also expanded 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 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. A new capital conservation buffer, comprised of Common Equity Tier 1 capital, is also established above the regulatory minimum capital requirements. This capital conservation buffer is being phased in, which began January 1, 2016, at 0.625% of risk-weighted assets, was 1.25% of risk-weighted assets effective January 1, 2017, and further increases each subsequent year by an additional 0.625% until reaching the final level of 2.5% on January 1, 2019. 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.

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, 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 $52.0$49.4 million as of SeptemberJune 30, 2016,2017, compared with $47.1$43.2 million as of December 31, 2015.2016. Interest-bearing deposits in banks at SeptemberJune 30, 2016, increased to $6.32017, were $3.2 million, an increase of $3.6$1.4 million from $1.8 million at December 31, 2015.2016. Investment securities classified as available for sale, totaling $436.2$443.0 million and $427.2$477.5 million as of SeptemberJune 30, 20162017 and December 31, 2015,2016, respectively, could be sold to meet liquidity needs if necessary. Additionally, the Bank maintains 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 believed that the Company had sufficient liquidity as of SeptemberJune 30, 20162017 to meet the needs of borrowers and depositors.
Our principal sources of funds between December 31, 20152016 and SeptemberJune 30, 20162017 were proceeds proceeds from the maturity and sale of investment securities and FHLB borrowings.the issuance of common stock. While scheduled loan amortization and maturing interest-bearing deposits in banks are relatively predictable sources of funds, deposit flows and loan prepayments are greatly influenced by economic

conditions, the general level of interest rates, and competition. We 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 SeptemberJune 30, 2016,2017, we had $18.8$15.0 million of long-term debt outstanding to an unaffiliated banking organization. See Note 11.10. “Long-Term Borrowings” to our consolidated financial statements for additional information related to our long-term debt. We also have $23.7 million of indebtedness payable under junior subordinated debentures issued to subsidiary trusts that issued trust preferred securities in pooled offerings. See Note 10.9. “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. The price of one or more of the components of the Consumer Price Index (“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, standby and performance letters of credit, and commitments to originate residential mortgage loans held for sale. 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 off-balance-sheet 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 SeptemberJune 30, 2016,2017, outstanding commitments to extend credit totaled approximately $439.1$517.2 million. We have established a reserve of $0.3$0.2 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 totalled $12.7totaled $11.6 million as of SeptemberJune 30, 2016.2017. 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 SeptemberJune 30, 20162017, there were approximately $2.71.6 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 $31.7$23.2 million in the first ninesix months of 2016,2017, compared with $22.1$20.3 million in the first ninesix months of 2015.2016. Net income before depreciation, amortization, and accretion is generally the primary contributor for net cash inflows from operating activities.
Net cash outflows from investing activities were $26.8$10.9 million in the first ninefirst six months of 2016,2017, compared to net cash inflows of $53.1$38.2 million in the comparable nine-monthsix-month period of 2015.2016. In the first ninesix months of 2016,2017, investment securities transactions resulted in net cash outflowsinflows of $39.4$24.2 million, compared to inflows of $155.8$51.9 million during the same period of 2015. The sale of our Rice Lake and Barron, Wisconsin and Davenport, Iowa branch offices contributed to net2016. Net cash inflowsoutflows related to the net decreaseincrease in loans of $7.1were $34.2 million for the first ninesix months of 2016,2017, compared with $89.5$17.6 million of net cash outflows related to the net increase in loans for the same period of 2015.2016. Purchases of premises and equipment resulted in $4.6$1.7 million cash outflows in the first ninesix months of 2016,2017, compared to outflows of $11.6$4.0 million in the comparable period of 2015, reflecting the finalization of the construction of a new Home Mortgage and Operations Center, which was complete at the end of 2015, at a total cost of $16.0 million, and the restoration and remodeling of the building that serves as the main office of the Bank and headquarters of the Company, which was completed in April 2016 at a cost of $13.8 million. There were no cash inflows from loan pool participations during the first nine months of 2016 compared to $19.3 million during the same period of 2015, as we sold our interest in these instruments in the second quarter of 2015.2016.
Net cash inflowsoutflows from financing activities in the first ninesix months of 2016 was $2.0 thousand,2017 were $6.2 million, compared with net cash outflowsinflows of $6.3$5.4 million for the same period of 2015.2016. The largest financing cash outflows during the ninesix months ended SeptemberJune 30, 2016 was2017 were a net decrease of $17.6$25.0 million in deposits, the use of $5.5FHLB borrowings, a $22.0 million to pay dividends, a $4.0 million and decrease in securities sold under agreement to repurchase, the use of $3.9 million to pay dividends, and $3.8$2.5 million of payments on long-term debt. Sources of cash inflows during the first ninesix months of 20162017 were $24.4 million of proceeds, net of expenses, from the issuance of common stock, an increase of $17.8$13.3 million in deposits, and an increase of $9.6 million in federal funds purchased, and a net increase of $13.0 million in FHLB borrowings.purchased.
To further mitigate liquidity risk, the Bank has several sources of liquidity in place to maximize funding availability and increase the diversification of funding sources. The criteria for evaluating the use of these sources include volume concentration (percentage of liabilities), cost, volatility, and the fit with the current asset/liability management plan. These acceptable sources of liquidity include:
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 the 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. Currently, the Bank has unsecured federal funds lines totaling $95.0$110.0 million, which lines are tested annually to ensure availability.

FHLB Borrowings:
FHLB borrowings provide both a source of liquidity and long-term funding for the Bank. Use of this type of funding is coordinated with both the strategic balance sheet growth projections and interest rate risk profile of the 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 SeptemberJune 30, 20162017, the Bank had $100.090.0 million in outstanding FHLB borrowings, leaving $226.5193.0 million available for liquidity needs, based on collateral capacity. These borrowings are secured by various real estate loans (residential, commercial and agricultural).

Brokered Deposits:
The Bank has brokered certificate of deposit lines/lines and 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 Bank’s core market area, is reflected in an internal policy stating that the Bank limit the use of brokered deposits as a funding source to no more than 10% of total assets. Board approval is required to exceed this limit. theThe 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 it 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 SeptemberJune 30, 20162017.
Federal Reserve Bank Discount Window:
The Federal Reserve Bank Discount Window is another source of liquidity, particularly during difficult economic times. theThe Bank has a borrowing capacity with the Federal Reserve Bank of Chicago limited by the amount of municipal securities pledged against the line. As of SeptemberJune 30, 20162017, the Bank had municipal securities with an approximate market value of $13.213.0 million pledged for liquidity purposes.purposes, and had a borrowing capacity of $11.7 million.
Interest Rate Risk
Interest rate risk is defined as the exposure of net interest income and fair value of financial instruments (interest-earning assets, deposits and borrowings) to movements in interest rates. The Company’s results of operations depend to a large degree on its net interest income and its ability to manage interest rate risk. The Company considers interest rate risk to be one of its more significant market risks. The major sources of the Company's interest rate risk are timing differences in the maturity and re-pricing characteristics of assets and liabilities, changes in the shape of the yield curve, changes in customer behavior and changes in relationships between rate indices (basis risk). Management measures these risks and their impact in various ways, including through the use of income simulation and valuation analyses. The interest rate scenarios used in such analysis may include gradual or rapid changes in interest rates, spread narrowing and widening, yield curve twists and changes in assumptions about customer behavior in various interest rate scenarios. A mismatch between maturities, interest rate sensitivities and prepayment characteristics of assets and liabilities results in interest-rate risk. Like most financial institutions, we have material interest-rate risk exposure to changes in both short-term and long-term interest rates, as well as variable interest rate indices (e.g., the prime rate or LIBOR). There has been very littleno material change in the Company’s interest rate profile between SeptemberJune 30, 20162017 and December 31, 2015.2016. The mix of earning assets and interest-bearing liabilities has remained stable over the period.
The Bank’s asset and liability committee meets regularly and is responsible for reviewing its interest rate sensitivity position and establishing policies to monitor and limit exposure to interest rate risk. 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.
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. There are two primary tools used to evaluate interest rate risk: net interest income simulation and

economic value of equity ("EVE"). In addition, interest rate gap is reviewed to monitor asset and liability repricing over various time periods.
Net Interest Income Simulation: 
Management utilizes net interest income simulation models to estimate the near-term effects of changing interest rates on its net interest income. Net interest income simulation involves forecasting net interest income under a variety of scenarios, which include varying the level of interest rates and the shape of the yield curve. Management exercises its best judgment in making assumptions regarding events that management can influence, such as non-contractual deposit re-pricings, and events outside management's control, such as customer behavior on loan and deposit activity and the effect that competition has on both loan

and deposit pricing. These assumptions are subjective and, as a result, net interest income simulation results will differ from actual results due to the timing, magnitude and frequency of interest rate changes, changes in market conditions, customer behavior and management strategies, among other factors. We perform various sensitivity analyses on assumptions of deposit attrition and deposit re-pricing.
The following table presents the anticipated effect on net interest income over a twelve month period if short- and long-term interest rates were to sustain an immediate decrease of 100 basis points, or an immediate increase of 100 basis points andor 200 basis points:
  Immediate Change in Rates

As of SeptemberJune 30, 2016, 40.3%2017, 38.1% of the Company’s earning asset balances will reprice or are expected to pay down in the next twelve months, and 45.6%64.4% of the Company’s deposit balances are low cost or no cost deposits.
Economic Value of Equity: 
Management also uses EVE to measure risk in the balance sheet that might not be taken into account in the net interest income simulation analysis. Net interest income simulation highlights exposure over a relatively short time period, while EVE analysis incorporates all cash flows over the estimated remaining life of all balance sheet positions. The valuation of the balance sheet, at a point in time, is defined as the discounted present value of asset cash flows minus the discounted present value of liability cash flows. EVE analysis addresses only the current balance sheet and does not incorporate the run-off replacement assumptions that are used in the net interest income simulation model. As with the net interest income simulation model, EVE analysis is based on key assumptions about the timing and variability of balance sheet cash flows and does not take into account any potential responses by management to anticipated changes in interest rates.
Interest Rate Gap: 
The interest rate gap is the difference between earning assets and interest-bearing liabilities re-pricing within a given period and represents the net asset or liability sensitivity at a point in time. An interest rate gap measure could be significantly affected by external factors such as loan prepayments, early withdrawals of deposits, changes in the correlation of various interest-bearing instruments, competition, or a rise or decline 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 SeptemberJune 30, 20162017. 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.

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, 20152016. 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.
         
We did not repurchase any of our equity securities during the thirdsecond quarter of 2016.2017.
On July 21, 2016, 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, 2018. The new repurchase program replaced the Company’s prior repurchase program, pursuant to which the Company had repurchased $1.2 million of common stock since the plan was announced in July 2014. Pursuant to the repurchase 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, $5.0 million remained available for possible future repurchases as of SeptemberJune 30, 2016.2017.

Item 3. Defaults Upon Senior Securities.
