CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. These forward-looking statements reflect our current views with respect to, among other things, future events and our financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “might,” “should,” “could,” “predict,” “potential,” “believe,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “projection,” “would,” “annualized” and “outlook,” or the negative version of those words or other comparable words or phrases of a future or forward-looking nature. These forward-looking statements are not historical facts, and are based on current expectations, estimates and projections about our industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions, estimates and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements.

- 3-

A number of important factors could cause our actual results to differ materially from those indicated in these forward-looking statements, including those factors identified in “Item 1A. Risk Factors” or “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Report or the following:

• current and future economic and market conditions in the United States generally or in our states in particular, including the rate of growth and employment levels;

• the effect of the current low interest rate environment or changes in market interest rates;

• the geographic concentration of our operations, and our concentration on originating business and agribusiness loans;

• the relative strength or weakness of the agricultural and commercial credit sectors and of the real estate markets in the markets in which our borrowers are located;

• declines in the market prices for agricultural products;

• our ability to effectively execute our strategic plan and manage our growth;

• our ability to successfully manage our credit risk and the sufficiency of our allowance for loan and lease loss;

• our ability to attract and retain skilled employees or changes in our management personnel;

• our ability to effectively compete with other financial services companies and the effects of competition in the financial services industry on our business;

• changes in the demand for our products and services;

• the effectiveness of our risk management and internal disclosure controls and procedures;

• fluctuations in the values of our assets and liabilities and off-balance sheet exposures;

• our ability to attract and retain customer deposits;

• our access to sources of liquidity and capital to address our liquidity needs;

• possible changes in trade, monetary and fiscal policies of, and other activities undertaken by, governments, agencies, central banks and similar organizations;

• our ability to identify and address cyber-security risks;

• any failure or interruption of our information and communications systems;

• our ability to keep pace with technological changes;

• our ability to successfully develop and commercialize new or enhanced products and services;

• possible impairment of our goodwill and other intangible assets, or any adjustment of the valuation of our deferred tax assets;

• the effects of problems encountered by other financial institutions;

• the effects of geopolitical instability, including war, terrorist attacks, and man-made and natural disasters;

• the effects of the failure of any component of our business infrastructure provided by a third party;

• the impact of, and changes in applicable laws, regulations and accounting standards and policies;

- 4-

• market perceptions associated with our separation from NAB and other aspects of our business;

• our likelihood of success in, and the impact of, litigation or regulatory actions;

• our inability to receive dividends from our bank and to service debt, pay dividends to our common stockholders and satisfy obligations as they become due;

• the incremental costs of operating as a standalone public company;

• our ability to meet our obligations as a public company, including our obligations under Section 404 of the Sarbanes-Oxley Act of 2002 to maintain an effective system of internal control over financial reporting;

• our ability to retain service providers to perform oversight or control functions or services that have otherwise been performed in the past by NAB;

• various risks and uncertainties associated with our recently completed acquisition of HF Financial Corp. (“HF Financial”), including, without limitation, our ability to effectively and timely integrate HF Financial’s operations into our operations, our ability to achieve the estimated synergies from the proposed transaction, litigation related to the proposed transaction and the effects of the proposed transaction, on our future financial condition, operating results, strategy and plans;

• damage to our reputation from any of the factors described above; and

• other risks and uncertainties inherent to our business, including those discussed under the heading "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended September 30, 2015.

The foregoing factors should not be considered an exhaustive list and should be read together with the other cautionary statements included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2015. If one or more events related to these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may differ materially from what we anticipate. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and we do not undertake any obligation to update or review any forward-looking statement, whether as a result of new information, future developments or otherwise.

GREAT WESTERN BANCORP, INC.

Notes to Consolidated Financial Statements (Unaudited)

1. Nature of Operations and Summary of Significant Policies

Nature of Operations

Great Western Bancorp, Inc. (the “Company”) is a bank holding company organized under the laws of Delaware. The primary business of the Company is ownership of its wholly owned subsidiary, Great Western Bank (the “Bank”). The Bank is a full-service regional bank focused on relationship-based business and agribusiness banking in Arizona, Colorado, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota and South Dakota. The Company and the Bank are subject to the regulation of certain federal and/or state agencies and undergo periodic examinations by those regulatory authorities. Substantially all of the Company’s income is generated from banking operations.

Basis of Presentation

The accompanying unaudited consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and reflect all adjustments that are, in the opinion of management, necessary for the fair presentation of the financial position and results of operations for the periods presented. All such adjustments are of a normal recurring nature.

Certain previously reported amounts have been reclassified to conform to the current presentation.

The unaudited interim consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended September 30, 2015, which includes a description of significant accounting policies. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year or any other period.

The accompanying unaudited consolidated financial statements include the accounts and results of operations of the Company and its subsidiaries after elimination of all significant intercompany accounts and transactions. The preparation of unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates.

Business Combinations

The Company accounts for business combinations under the acquisition method of accounting in accordance with ASC 805, “Business Combinations” (“ASC 805”). The Company recognizes the fair value of the assets acquired and liabilities assumed, immediately expenses transaction costs and accounts for restructuring plans separately from the business combination. There is no separate recognition of the acquired allowance for loan and lease losses on the acquirer’s balance sheet as credit related factors are incorporated directly into the fair value of the loans recorded at the acquisition date. The excess of the cost of the acquisition over the fair value of the net tangible and intangible assets acquired is recorded as goodwill. Alternatively, a bargain purchase gain is recorded equal to the amount by which the fair value of assets purchased exceeds the fair value of liabilities assumed and consideration paid.

Results of operations of the acquired business are included in the consolidated statements of comprehensive income from the effective date of acquisition.

Securities

The Company classifies securities upon purchase in one of three categories: trading, held to maturity, or available for sale. Debt and equity securities held for resale are classified as trading. Debt securities for which the Company has the ability and positive intent to hold until maturity are classified as held to maturity. All other securities are classified as available for sale as they may be sold prior to maturity in response to changes in the Company’s interest rate risk profile, funding needs, demand for collateralized deposits by public entities or other reasons.

Held to maturity securities are stated at amortized cost, which represents actual cost adjusted for premium amortization and discount accretion. Available for sale securities are stated at fair value, with unrealized gains and losses, net of related taxes, included in stockholders’ equity as a component of accumulated other comprehensive income (loss).

Trading securities are stated at fair value. Realized and unrealized gains and losses from sales and fair value adjustments of trading securities are included in other noninterest income in the consolidated statements of comprehensive income.

Purchases and sales of securities are recognized on a trade date basis. The cost of securities sold is based on the specific identification method.

Declines in the fair value of investment securities available for sale (with certain exceptions for debt securities noted below) that are deemed to be other-than-temporary are recognized in earnings as a realized loss, and a new cost basis for the securities is established. In evaluating other-than-temporary impairment, management considers the length of time and extent to which the fair value has been less than amortized cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value in the near term. Declines in the fair value of debt securities below amortized cost are deemed to be other-than-temporary in circumstances where: (1) the Company has the intent to sell a security; (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security. If the Company intends to sell a security or if it is more likely than not that the Company will be required to sell the security before recovery, an other-than-temporary impairment loss is recognized in earnings equal to the difference between the security’s amortized cost basis and its fair value. If the Company does not intend to sell the security or it is not more likely than not that it will be required to sell the security before recovery, the other-than-temporary impairment write-down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in accumulated other comprehensive income (loss).

Interest and dividends, including amortization of premiums and accretion of discounts, are recognized as interest or dividend income when earned. Realized gains and losses on sales (using the specific identification method) and declines in value judged to be other- than-temporary are included in noninterest income in the consolidated statements of comprehensive income.

Loans

The Company’s accounting method for loans differs depending on whether the loans were originated or purchased and, for purchased loans, whether the loans were acquired at a discount related to evidence of credit deterioration since date of origination.

Originated Loans

Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or pay-off, generally are reported at their outstanding principal balance, adjusted for charge-offs, the allowance for loan and lease losses, and any unamortized deferred fees or costs. Other fees, not associated with originating a loan are recognized as fee income when earned.

Interest income on loans is accrued daily on the outstanding balances. Accrual of interest is discontinued when management believes, after considering collection efforts and other factors, the borrower’s financial condition is such that collection of interest is doubtful, which is generally at 90 days past due. Generally, when loans are placed on nonaccrual status, interest receivable is reversed against interest income in the current period. Interest payments received thereafter are applied as a reduction to the remaining principal balance as long as concern exists as to the ultimate collection of the principal. Loans are removed from nonaccrual status when they become current as to both principal and interest and concern no longer exists as to the collectability of principal and interest.

The Company has elected to measure certain long-term loans and written loan commitments at fair value to assist in managing interest rate risk for longer-term loans. Fair value loans are fixed-rate loans having original maturities of 5 years or greater (typically between 5 and 15 years) to our business and agribusiness banking customers to assist them in facilitating their risk management strategies. The fair value option was elected upon the origination or acquisition of these loans and written loan commitments. Interest income is recognized in the same manner on loans reported at fair value as on non-fair value loans, except in regard to origination fees and costs which are recognized immediately upon closing. The changes in fair value of long-term loans and written loan commitments at fair value are reported in noninterest income.

For loans held for sale, loan fees charged or received on origination, net of certain direct loan origination costs, are recognized in income when the related loan is sold. For loans held for investment, loan fees, net of certain direct loan origination costs, are deferred,

and the net amount is amortized as an adjustment of the related loan’s yield. The Company is generally amortizing these amounts over the contractual lives of the loans. Commitment fees are recognized as income when received.

The Company grants commercial, agricultural, consumer, residential real estate, and other loans to customers primarily in Arizona, Colorado, Iowa, Kansas, Missouri, Minnesota, Nebraska, North Dakota and South Dakota. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the borrower. Collateral held varies but includes accounts receivable, inventory, property and equipment, residential real estate, and income-producing commercial and agricultural properties. Government guarantees are also obtained for some loans, which reduces the Company’s risk of loss.

Loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value. Loans held for sale include fixed rate single-family residential mortgage loans under contract to be sold in the secondary market. In most cases, loans are carried at cost and sold within 45 days. These loans are sold with the mortgage servicing rights released. Under limited circumstances, buyers may have recourse to return a purchased loan to the Company. Recourse conditions may include early payment default, breach of representation or warranties, or documentation deficiencies.

Fair value of loans held for sale is determined based on prevailing market prices for loans with similar characteristics, sale contract prices, or, for certain portfolios, discounted cash flow analysis. Declines in fair value below cost (and subsequent recoveries) are recognized in net gain on sale of loans. Deferred fees and costs related to these loans are not amortized but are recognized as part of the cost basis of the loan at the time it is sold. Gains or losses on sales are recognized upon delivery and included in net gain on sale of loans.

Purchased Loans

Loans acquired (non-impaired and impaired) in a business acquisition are recorded at their fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date.

In determining the acquisition date fair value of purchased loans with evidence of credit deterioration (“ASC 310-30 loans”), and in subsequent accounting, the Company generally aggregates impaired purchased consumer and certain smaller balance impaired commercial loans into pools of loans with common risk characteristics, while accounting for larger-balance impaired commercial loans individually. Expected cash flows at the acquisition date in excess of the fair value of loans are recorded as interest income over the life of the loans using a level-yield method.

Management estimates the cash flows expected to be collected at acquisition and at subsequent measurement dates using internal risk models, which incorporate the estimate of key assumptions, such as default rates, loss severity, and prepayment speeds. Subsequent to the acquisition date, decreases in cash flows over those expected at the acquisition date are recognized by recording an allowance for loan and lease losses. Subsequent increases in cash flow over those expected at the acquisition date are recognized as reductions to allowance for loan and lease losses to the extent impairment was previously recognized and thereafter as interest income prospectively.

For purchased loans not deemed impaired at the acquisition date, the difference between the fair value and the unpaid principal balance of the loan at acquisition date is amortized or accreted to interest income using the effective interest method over the remaining period to contractual maturity.

Credit Risk Management

The Company’s strategy for credit risk management includes well-defined, centralized credit policies, uniform underwriting criteria and ongoing risk monitoring and review processes for all credit exposures. The strategy also emphasizes diversification on a geographic, industry, and customer level; regular credit examinations; and management reviews of loans exhibiting deterioration of credit quality. The credit risk management strategy also includes a credit risk assessment process that performs assessments of compliance with commercial and consumer credit policies, risk ratings, and other critical credit information. Loan decisions are documented with respect to the borrower’s business, purpose of the loan, evaluation of the repayment sources, and the associated risks, evaluation of collateral, covenants and monitoring requirements, and risk rating rationale.

The Company categorizes its loan portfolio into six classes, which is the level at which it develops and documents a systematic methodology to determine the allowance for loan and lease losses. The Company’s six loan portfolio classes are residential real estate, commercial real estate, commercial non real estate, agriculture, consumer and other lending.

The residential real estate lending class includes loans made to consumer customers including residential mortgages, residential construction loans and home equity loans and lines. These loans are typically fixed rate loans secured by residential real estate. Home equity lines are revolving accounts giving the borrower the ability to draw and repay balances repeatedly, up to a maximum commitment, and are secured by residential real estate. Home equity lines typically have variable rate terms which are benchmarked to a prime rate. Historical loss history is the primary factor in determining the allowance for loan and lease losses for the residential real estate lending class. Key risk characteristics relevant to residential real estate lending class loans primarily relate to the borrower’s capacity and willingness to repay and include unemployment rates and other economic factors, and customer payment history. These risk characteristics, among others, are reflected in the environmental factors considered in determining the allowance for loan and lease losses.

The commercial real estate lending class includes loans made to small and middle market businesses, including multifamily properties. Loans in this class are secured by commercial real estate. Historical loss history and updated loan-to-value information on collateral-dependent loans are the primary factors in determining the allowance for loan and lease losses for the commercial real estate lending class. Key risk characteristics relevant to the commercial real estate lending class include the industry and geography of the borrower’s business, purpose of the loan, repayment sources, borrower’s debt capacity and financial performance, loan covenants, and nature of pledged collateral. We consider these risk characteristics in assigning risk ratings and estimating environmental factors considered in determining the allowance for loan and lease losses.

The commercial non real estate lending class includes loans made to small and middle market businesses, and loans made to public sector customers. Loans in this class are generally secured by business assets and guaranteed by owners; cashflows are most often our primary source of repayment. Historical loss history and updated loan-to-value information on collateral-dependent loans are the primary factors in determining the allowance for loan and lease losses for the commercial non real estate lending class. Key risk characteristics relevant to the commercial non real estate lending class include the industry and geography of the borrower’s business, purpose of the loan, repayment sources, borrower’s debt capacity and financial performance, loan covenants, and nature of pledged collateral. We consider these risk characteristics in assigning risk ratings and estimating environmental factors considered in determining the allowance for loan and lease losses.

The agriculture lending class includes loans made to small and mid-size agricultural businesses and individuals. Loans in this class are generally secured by operating assets and guaranteed by owners; cashflows are most often our primary source of repayment. Historical loss history and updated loan-to-value information on collateral-dependent loans are the primary factors in determining the allowance for loan and lease losses for the agriculture lending class. Key risk characteristics relevant to the agriculture lending class include the geography of the borrower’s operations, commodity prices and weather patterns, purpose of the loan, repayment sources, borrower’s debt capacity and financial performance, loan covenants, and nature of pledged collateral. We consider these risk characteristics in assigning risk ratings and estimating environmental factors considered in determining the allowance for loan and lease losses.

The consumer lending class includes loans made to consumer customers including loans secured by automobiles and other installment loans, and the other lending class includes credit card loans and unsecured revolving credit lines. Historical loss history is the primary factor in determining the allowance for loan and lease losses for the consumer and other lending classes. Key risk characteristics relevant to loans in the consumer and other lending classes primarily relate to the borrower’s capacity and willingness to repay and include unemployment rates and other economic factors, and customer payment and overall credit history. These risk characteristics, among others, are reflected in the environmental factors considered in determining the allowance for loan and lease losses.

The Company assigns all non-consumer loans a credit quality risk rating. These ratings are Pass, Watch, Substandard, Doubtful, and Loss. Loans with a Pass and Watch rating represent those loans not classified on the Company’s rating scale for problem credits, with loans with a Watch rating being monitored and updated at least quarterly by management. Substandard loans are those where a well-defined weakness has been identified that may put full collection of contractual debt at risk. Doubtful loans are those where a well-defined weakness has been identified and a loss of contractual debt is probable. Substandard and doubtful loans are monitored and updated monthly. All loan risk ratings are updated and monitored on a continuous basis. The Company generally does not risk rate consumer loans unless a default event such as bankruptcy or extended nonperformance takes place. Alternatively, standard credit scoring systems are used to assess credit risks of consumer loans.

Troubled Debt Restructurings (“TDRs”)

Loans modified under troubled debt restructurings involve granting a concession to a borrower who is experiencing financial difficulty. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance, or other actions intended to maximize collection, which generally would not otherwise be considered. Our TDRs include performing and nonperforming TDRs, which consist of loans that continue to accrue interest at the loan's original interest rate as we expect to collect the remaining principal and interest on the loan, and nonaccrual TDRs, which include loans that are in a nonaccrual status and are no longer accruing interest, as we do not expect to collect the full amount of principal and interest owned from the borrower on these loans. At the time of modification (except for loans on nonaccrual status), a TDR is classified as nonperforming TDR until a six-month payment history of principal and interest payments, in accordance with the terms of the loan modification, is sustained, at which time we move the loan to a performing status (performing TDR). If we do not expect to collect all principal and interest on the loan, the modified loan is classified as a nonaccrual TDR. All TDRs are accounted for as impaired loans and are included in our analysis of the allowance for loan and lease losses. A TDR that has been re-underwritten and renewed for a borrower who is no longer experiencing financial difficulty and which yields a market rate of interest at the time of a renewal is no longer considered a TDR.

Allowance for Loan and Lease Losses (“ALLL”) and Unfunded Commitments

The Company maintains an allowance for loan and lease losses at a level management believes is appropriate to reserve for credit losses inherent in our loan portfolio. The allowance for loan and lease losses is determined based on an ongoing evaluation, driven primarily by monitoring changes in loan risk grades, delinquencies, and other credit risk indicators, which is inherently subjective.

The Company considers the uncertainty related to certain industry sectors and the extent of credit exposure to specific borrowers within the portfolio. In addition, consideration is given to concentration risks associated with the various loan portfolios and current economic conditions that might impact the portfolio. The Company also considers changes, if any, in underwriting activities, the loan portfolio composition (including product mix and geographic, industry, or customer-specific concentrations), trends in loan performance, the level of allowance coverage relative to similar banking institutions and macroeconomic factors, such as changes in unemployment rates, gross domestic product, and consumer bankruptcy filings.

All of these estimates are susceptible to significant change. Changes to the allowance for loan and lease losses are made by charges to the provision for loan and lease losses, which is reflected in the consolidated statements of comprehensive income. Past due status is monitored as an indicator of credit deterioration. Loans that are 90 days or more past due are put on nonaccrual status unless the loan is well secured and in the process of collection. Loans deemed to be uncollectible are charged off against the allowance for loan and lease losses. Recoveries of amounts previously charged-off are credited to the allowance for loan and lease losses.

The allowance for loan and lease losses consist of reserves for probable losses that have been identified related to specific borrowing relationships that are individually evaluated for impairment (“specific reserve”), as well as probable losses inherent in our loan portfolio that are not specifically identified (“collective reserve”).

The specific reserve relates to impaired loans. A loan is impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due (interest as well as principal) according to the contractual terms of the loan agreement. Specific reserves are determined on a loan-by-loan basis based on management’s best estimate of the Company’s exposure, given the current payment status of the loan, the present value of expected payments, and the value of any underlying collateral. Impaired loans also include loans modified in troubled debt restructurings. Generally, the impairment related to troubled debt restructurings is measured based on the fair value of the collateral, less cost to sell, or the present value of expected payments relative to the unpaid principal balance. If the impaired loan is identified as collateral dependent, then the fair value of the collateral method of measuring the amount of the impairment is utilized. This method requires obtaining an independent appraisal of the collateral and applying a discount factor to the appraised value, if necessary, and including costs to sell.

Management’s estimate for collective reserves reflects losses incurred in the loan portfolio as of the consolidated balance sheet reporting date. Incurred loss estimates primarily are based on historical loss experience and portfolio mix. Incurred loss estimates may be adjusted for qualitative factors such as current economic conditions and current portfolio trends including credit quality, concentrations, aging of the portfolio, and/or significant policy and underwriting changes.

The Company maintains an ALLL for acquired impaired loans accounted for under ASC 310-30, resulting from decreases in expected cash flows arising from the periodic revaluation of these loans. Any decrease in expected cash flows in the individual loan pool is generally recognized in the current provision for loan and lease losses. Any increase in expected cash flows is generally not recognized immediately, but is instead reflected as an adjustment to the related loan or pool's yield on a prospective basis once any previously recorded provision for loan and lease loss has been recognized.

For acquired nonimpaired loans accounted for under ASC 310-20, the Company utilizes methods to estimate the required allowance for loan and lease losses similar to originated loans; the required reserve is compared to the net carrying value of each acquired nonimpaired loan (by segment) to determine if a provision is required.

While management uses the best information available to establish the allowance for loan and lease losses, future adjustments may be necessary if economic conditions differ substantially from the assumptions used in performing the estimates.

Unfunded residential mortgage loan commitments entered into in connection with mortgage loans to be held for sale are considered derivatives and are recorded at fair value and included in other liabilities on the consolidated balance sheets with changes in fair value recorded in other interest income. All other unfunded loan commitments are generally related to providing credit facilities to customers and are not considered derivatives. For purchased loans, the fair value of the unfunded credit commitments is considered in determination of the fair value of the loans recorded at the date of acquisition. Reserves for credit exposure on all other unfunded credit commitments are recorded in other liabilities on the consolidated balance sheets.

FDIC Indemnification Asset and Clawback Liability

In conjunction with a Federal Deposit Insurance Corporation (“FDIC”)-assisted transaction of TierOne Bank in 2010, the Company entered into two loss share agreements with the FDIC, one covering certain single family residential mortgage loans with the claim period ending June 2020 and one covering commercial loans and other assets, in which the claim period ended in June 2015. The agreements cover a portion of realized losses on loans, foreclosed real estate and certain other assets. The Company has recorded assets on the consolidated balance sheets (i.e. indemnification assets) representing estimated future amounts recoverable from the FDIC.

Fair values of loans covered by the loss sharing agreements at the acquisition date were estimated based on projected cash flows available based on the expected probability of default, default timing and loss given default, the expected reimbursement rates (generally 80%) from the FDIC and other relevant terms of the loss sharing agreements. The initial fair value was established by discounting these expected cash flows with a market discount rate for instruments with like maturity and risk characteristics.

The loss share assets are measured separately from the related loans and foreclosed real estate and recorded as an FDIC indemnification asset on the consolidated balance sheets because they are not contractually embedded in the loans and are not transferable with the loans should the Company choose to dispose of them. Subsequent to the acquisition date, reimbursements received from the FDIC for actual incurred losses reduce the carrying amount of the loss share assets. Reductions to expected losses on covered assets, to the extent such reductions to expected losses are the result of an improvement to the actual or expected cash flows from the covered assets, also reduce the carrying amount of the loss share assets. The rate of accretion of the indemnification asset discount included in interest income slows to mirror the accelerated accretion of the loan discount. Additional expected losses on covered assets, to the extent such expected losses result in the recognition of an allowance for loan and lease losses, increase the carrying amount of the loss share assets. A related increase in the value of the indemnification asset up to the amount covered by the FDIC is calculated based on the reimbursement rates from the FDIC and is included in other noninterest income. The corresponding loan accretion or amortization is recorded as a component of interest income on the consolidated statements of comprehensive income. Although these assets are contractual receivables from the FDIC, there are no contractual interest rates.

As part of the loss sharing agreements, the Company also assumed a liability (“FDIC Clawback Liability”) to be paid within 45 days subsequent to the maturity or termination of the loss sharing agreements that is contingent upon actual losses incurred over the life of the agreements relative to expected losses considered in the consideration paid at acquisition date and the amount of losses reimbursed to the Company under the loss sharing agreements. The liability was recorded at fair value as of the acquisition date. The fair value was based on a discounted cash flow calculation that considered the formula defined in the loss sharing agreements and projected losses. The difference between the fair value at acquisition date and the projected losses is amortized through other noninterest

expense. As projected losses and reimbursements are updated, as described above, the FDIC Clawback Liability is adjusted and a gain or loss is recorded in other noninterest expense.

Loan Servicing Rights

The Company records a servicing asset for contractually separated servicing from the underlying mortgage loans. Fair value is based on market prices for comparable mortgage servicing contracts, when available or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The asset is amortized into mortgage banking income, net on the consolidated statement of comprehensive income in proportion to and over the period of estimated net servicing income.

Loan servicing rights are evaluated for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is determined by stratifying rights into groupings based on characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists, a reduction of the allowance may be recorded as an increase to noninterest income. If the Company determines the impairment to be permanent, the valuation is written off against the loan servicing rights, which results in a new amortized balance. Changes in the valuation allowance are reported in mortgage banking income, net in the consolidated statement of comprehensive income. The fair value of loan servicing rights is subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Estimating future cash flows on the underlying mortgages is a difficult analysis and requires judgment based on the best information available. Based on the Company's analysis of loan servicing rights, a valuation allowance of $0.2 million was recorded at June 30, 2016.

Servicing fee income, which is reported in noninterest income, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding balance or a fixed amount per loan and are recorded as income as earned. The amortization of loan servicing rights is netted against mortgage banking income, net in the statement of consolidated comprehensive income.

Goodwill

Goodwill represents the cost in excess of the fair value of net assets acquired (including identifiable intangibles) in transactions accounted for as business acquisitions. Goodwill is evaluated annually for impairment or more frequently if events and circumstances exist that indicates that a goodwill impairment test should be performed. The Company performs its impairment evaluation as of June 30 of each fiscal year. If the implied fair value of goodwill is lower than its carrying amount, goodwill impairment is indicated and goodwill is written down to its implied fair value. Subsequent increases in goodwill are not recognized in the consolidated financial statements. No goodwill impairment was recognized during the three and nine months ended June 30, 2016 and 2015.

Core Deposits and Other Intangibles

Intangible assets consist of core deposits, brand intangible, customer relationships, and other intangibles. Core deposits represent the identifiable intangible value assigned to core deposit bases arising from purchase acquisitions. Brand intangible represents the value associated with the Bank charter. Customer relationships intangible represents the identifiable intangible value assigned to customer relationships arising from a purchase acquisition. Other intangibles represent contractual franchise arrangements under which the franchiser grants the franchisee the right to perform certain functions within a designated geographical area. The methods and lives used to amortize intangible assets are as follows:

Intangible	Method	Years
Core deposit	Straight-line or effective yield	5 - 10
Brand intangible	Straight-line	15
Customer relationships	Straight-line	8.5
Other intangibles	Straight-line	1.25 - 9.33

Intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. No intangible asset impairments were recognized during the periods ended June 30, 2016 and 2015.

Derivatives

The Company maintains an overall interest rate risk management strategy that permits the use of derivative instruments to modify exposure to interest rate risk. The Company enters into interest rate swap contracts to offset the interest rate risk associated with borrowers who lock in long-term fixed rates (greater than or equal to 5 years to maturity) through a fixed rate loan. These contracts do not qualify for hedge accounting. Generally, under these swaps, the Company agrees with various swap counterparties to exchange the difference between fixed-rate and floating-rate interest amounts based upon notional principal amounts. These interest rate derivative instruments are recognized as assets and liabilities on the consolidated balance sheets and measured at fair value, with changes in fair value reported in net realized and unrealized gain (loss) on derivatives. Since each fixed rate loan is paired with an offsetting derivative contract, the impact to net income is minimized.

The Company enters into forward interest rate lock commitments on mortgage loans to be held for sale, which are commitments to originate loans whereby the interest rate on the loan is determined prior to funding. The Company also has corresponding forward sales contracts related to these interest rate lock commitments. Both the mortgage loan commitments and the related sales contracts are considered derivatives and are recorded at fair value with changes in fair value recorded in noninterest income.

Stock Based Compensation

Restricted and performance-based stock units/awards are classified as equity awards and accounted for under the Treasury method. Compensation expense for non-vested stock units/awards is based on the fair value of the award on the measurement date, which, for the Company, is the date of the grant and is recognized ratably over the vesting or performance period of the award. The fair value of non-vested stock units/awards is generally the market price of the Company's stock on the date of grant.

Income Taxes

The Company was required to file a consolidated income tax return with National Americas Investment, Inc. ("NAI") (a wholly owned indirect subsidiary of NAB) until NAI's dissolution on October 17, 2014. Income taxes are allocated pursuant to a tax-sharing arrangement, whereby the Company will pay federal and state income taxes as if it were filing on a stand-alone basis. Income tax expense includes two components: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over income. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods.

Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.

Tax benefits related to uncertain tax positions are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term "more likely than not" means a likelihood of more than 50 percent; the terms "examined" and "upon examination" also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information.

The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment.

Transfers of Financial Assets

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company-put presumptively beyond reach of the Company and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.

Securities sold under agreements to repurchase are accounted for as collateralized financing transactions and are recorded at amounts at which the securities were financed, plus accrued interest.

Defined Benefit Plan

The Company assumed plan sponsorship of the HF Financial Corp. Pension Plan during the quarter as part of the HF Financial acquisition. Defined benefit pension obligation and related costs are calculated using actuarial concepts and measurements. Three critical assumptions, the discount rate, the expected long-term rate of return on plan assets, and mortality rates are important elements of expense and/or benefit obligation measurements. Other assumptions involve employee demographic factors such as retirement patterns and turnover. The Company evaluates all assumptions annually. For accounting purposes, mortality assumptions at June 30, 2016 were based on the RP-2014 mortality tables and the MP 2015 projection scales.

The discount rate enables the Company to state expected future benefit payments as a present value on the measurement date. The Company determined the discount rate at June 30, 2016 by utilizing the standard duration index from the Citi Pension Discount Curve and Liability Index. A lower discount rate increases the present value of benefit obligations and increases pension expense.

To determine expected long-term rate of return on defined benefit pension plan assets, the Company considers the current asset allocation of the defined benefit pension plan, as well as historical and expected returns on each asset class. A lower expected rate of return on defined pension plan assets will increase pension expense.

The Company recognizes the over- or under-funded status of a plan as an other asset or other liability in the consolidated balance sheet as measured by the difference between the fair value of the plan assets and the projected benefit obligation. When recorded, unrecognized prior service costs and actuarial gains and losses are recognized as a component of accumulated other comprehensive income (loss).

Revenue Recognition

The Company recognizes revenue as it is earned based on contractual terms, as transactions occur, or as services are provided and collectability is reasonably assured. Certain specific policies related to service charges and other fees include the following:

Deposit Service Charges

Service charges on deposit accounts are primarily fees related to customer overdraft events and not sufficient funds fees, net of any refunded fees, and are recognized as transactions occur and services are provided. Service charges on deposit accounts also relate to monthly fees based on minimum balances, and are earned as transactions occur and services are provided.

Interchange Fees

Interchange fees include interchange income from consumer debit card transactions processed through card association networks. Interchange income is a fee paid by a merchant bank to the card-issuing bank through the interchange network. Interchange fees are set by the card association networks and are based on cardholder purchase volumes.

Wealth Management Fees

Wealth management fees include commission income from financial planning, investment management and insurance operations.

Comprehensive Income

Comprehensive income consists of net income and other comprehensive income, net of applicable income taxes. Other comprehensive income (loss) consists entirely of unrealized appreciation (depreciation) on available-for-sale securities.

The Company has evaluated all events or transactions that occurred through the date the Company issued these financial statements. During this period, the Company did not have any material recognizable or non-recognizable subsequent events other than outlined below.

On July 28, 2016, the board of directors of the Company declared a dividend of $0.14 per common share payable on August 24, 2016 to stockholders of record as of close of business on August 12, 2016.

2. New Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which addresses timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires institutions to measure all expected credit losses related to financial assets measured at amortized costs with an expected loss model based on historical experience, current conditions and reasonable and supportable forecasts relevant to affect the collectibility of the financial assets, which is referred to as the current expected credit loss (CECL) model. The ASU requires enhanced disclosures, including qualitative and quantitative requirements, to help understand significant estimates and judgments used in estimating credit losses, as well as provide additional information about the amounts recorded in the financial statements. ASU 2016-13 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted after December 15, 2018. The amendment requires the use of the modified retrospective approach for adoption. The Company is currently evaluating the potential impact of ASU 2016-13 on our financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Based Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which addresses 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. ASU 2016-09 is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Earlier application is permitted. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The Company is currently evaluating the potential impact of ASU 2016-09 on our financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires that lessees recognize the assets and liabilities arising from leases on the balance sheet. ASU 2015-16 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the potential impact of ASU 2016-02 on our financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities, which addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the potential impact of ASU 2016-01 on our financial statements.

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805) - Simplifying the Accounting for Measurement-Period Adjustments, which requires that adjustments to provisional amounts that are identified during the measurement period of a business combination be recognized in the reporting period in which the adjustment amounts are determined. Furthermore, the income statement effects of such adjustments, if any, must be calculated as if the accounting had been completed at the acquisition date. The portion of the amount recorded in current-period earnings that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. Under previous guidance, adjustments to

provisional amounts identified during the measurement period are to be recognized retrospectively. ASU 2015-16 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Earlier application is permitted for financial statements that have not been issued, therefore the Company has elected to early adopt this ASU as of and for its quarter ended June 30, 2016. The adoption of ASU 2015-16 in the third quarter of 2016 did not have a material impact on the Company's consolidated balance sheet or consolidated statement of comprehensive income. See also Note 3 to these consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which implements a common revenue standard that clarifies the principles for recognizing revenue. 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 and services. In August 2015, the FASB issued ASU No. 2015-14 which deferred the effective date of ASU No. 2014-09 to annual reporting periods beginning after December 15, 2017. In March 2016, the FASB issued ASU No. 2016-08, which intends to improve the operability and understandability of the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU No. 2016-10, which clarifies guidance pertaining to the identification of performance obligations and the licensing implementation. In May 2016, the FASB issued ASU Nos. 2016-11 and 2016-12, which further clarify guidance and provide practical expedients related to the adoption of ASU No. 2014-09. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is currently evaluating the potential impact of these standards on our financial statements.

3. Acquisition Activity

On May 16, 2016, the Company acquired by merger 100% of HF Financial Corp ("HF Financial"), the holding company of Home Federal Bank. Under terms of the agreement, HF Financial's stockholders had the right to receive for each share of HF Financial common stock, at their election (but subject to proration in the event cash or stock is oversubscribed), either (i) 0.6500 share of the Company's common stock, or (ii) $19.50 in cash. The total consideration was prorated as necessary to ensure that 24.29% of the total outstanding shares of HF Financial common stock were exchanged for cash and 75.71% of the total outstanding shares of HF Financial common stock were exchanged for shares of the Company's common stock. Total merger consideration of $142.0 million was paid by the Company in the acquisition, which resulted in goodwill of $40.7 million, as shown in the table below. With this acquisition, the Company expanded its presence into North Dakota and Minnesota through the addition of 23 bank offices and experienced in-market teams. The Company projects increased revenues from additional locations and customers and cost savings will be recognized in future periods through the elimination of redundant operations. The following summarizes consideration paid and an allocation of purchase price to net assets acquired.

	Number of Shares	Amount
(In thousands)
Equity consideration:
Common stock issued	3,448,119	$	107,478
Non-equity consideration:
Cash		34,487
Total consideration paid		141,965
Fair value of net assets acquired including identifiable intangible assets		101,312
Goodwill		$	40,653

Goodwill of $40.7 million arising from the acquisition arose as a result of consideration in excess of net assets acquired. The amount of goodwill that is expected to be deductible for income tax purposes is $0.0 million. The fair value of intangible assets created in the acquisition was $7.9 million related to core deposits and other intangible assets.

Total liabilities assumed	1,020,729
Fair value of net identifiable assets acquired	101,312
Net purchase price	141,965
Goodwill	$	40,653

The Company accounted for the aforementioned business combination under the acquisition method in accordance with ASC Topic 805, Business Combinations. Accordingly, the purchase price is allocated to the fair value of the assets acquired and liabilities assumed as of the date of acquisition. The foregoing purchase price allocations on the acquisition are preliminary and will be finalized upon the receipt of final valuations on certain assets and liabilities. Upon receipt of final fair value estimates, which must be within one year of the acquisition date, the Company will make any final adjustments to the purchase price allocation and retrospectively adjust any goodwill recorded. Material adjustments to acquisition date estimated fair values would be recorded in the reporting period in which the adjustment amounts are determined. Information regarding the Company’s loan discount and related deferred tax asset, core deposit intangible asset and related deferred tax liability, as well as income taxes payable and the related deferred tax balances recorded in the acquisition may be adjusted as the Company refines its estimates. Determining the fair value of assets and liabilities, particularly illiquid assets and liabilities, is a complicated process involving significant judgment regarding estimates and assumptions used to calculate estimated fair value. Fair value adjustments based on updated estimates could materially affect the goodwill recorded on the acquisition. The Company may incur losses on the acquired loans that are materially different from losses the Company originally projected.

The results of the merged HF Financial operations are presented within the Company’s consolidated financial statements from the acquisition date. The disclosure of HF Financial's post-acquisition revenue and net income is not practical due to the combining of HF Financial’s operations with and into the Company as of the acquisition date. Acquisition-related transaction expenses associated with the HF Financial acquisition totaled $12.2 million and $12.9 million during the three and nine months ended June 30, 2016, respectively, and $0.0 million for the three and nine months ended June 30, 2015.

Proceeds from sales of securities available for sale were $120.9 million and $0.0 million for the three months ended June 30, 2016 and 2015, respectively, and $145.9 million and $55.1 million for the nine months ended June 30, 2016 and 2015, respectively. Gross gains (pre-tax) of $0.1 million and $0.0 million and gross losses (pre-tax) of $0.0 million and $0.0 million were realized on the sales for the three months ended June 30, 2016 and 2015, respectively. Gross gains (pre-tax) of $0.2 million and $0.6 million and gross losses (pre-tax) of $0.0 million and $0.5 million were realized on the sales for the nine months ended June 30, 2016 and 2015, respectively, using the specific identification method. The Company recognized an other-than-temporary impairment in net loss on sale of securities in the consolidated statements of comprehensive income of $0.0 million and $0.4 million on two security holdings attributable to credit for the three and nine months ended June 30, 2016. There was no other-than-temporary impairment recognized for the three and nine months ended June 30, 2015.

Securities with an estimated fair value of approximately $1.08 billion and $894.3 million at June 30, 2016 and September 30, 2015, respectively, were pledged as collateral on public deposits, securities sold under agreements to repurchase, and for other purposes as required or permitted by law. The counterparties do not have the right to sell or pledge the securities the Company has pledged as collateral.

As detailed in the following tables, certain investments in debt securities, which are approximately 15% and 36% of the Company’s investment portfolio at June 30, 2016 and September 30, 2015, respectively, are reported in the consolidated financial statements at an amount less than their amortized cost. Based on evaluation of available evidence, including recent changes in market interest rates, credit rating information, implicit or explicit government guarantees, and information obtained from regulatory filings, management believes the declines in fair value of these securities are temporary. As the Company does not intend to sell the securities and it is not more likely than not that the Company will be required to sell the securities before the recovery of their amortized cost basis, which may be maturity, the Company does not consider the securities to be other-than-temporarily impaired at June 30, 2016 or September 30, 2015.

The adjustments are included in noninterest expense.

Troubled Debt Restructurings

Included in certain loan categories in the impaired loans are troubled debt restructurings (“TDRs”) that were classified as impaired. These TDRs do not include purchased credit impaired loans. When the Company grants concessions to borrowers such as reduced interest rates or extensions of loan periods that would not be considered other than because of borrowers’ financial difficulties, the modification is considered a TDR. Specific reserves included in the allowance for loan and lease losses for TDRs were $10.0 million and $3.6 million at June 30, 2016 and September 30, 2015, respectively. Commitments to lend additional funds to borrowers whose loans were modified in a TDR were $0.2 million and $2.3 million as of June 30, 2016 and September 30, 2015, respectively.

The Company maintains an ALLL for acquired loans accounted for under ASC 310-30 as a result of impairment to loan pools arising from the periodic re-valuation of these loans. Any impairment in the individual pool is generally recognized in the current period as provision for loan and lease losses. Any improvement in the estimated cash flows, is generally not recognized immediately, but is instead reflected as an adjustment to the related loan pools yield on a prospective basis once any previously recorded impairment has been recaptured.

The ALLL for ASC 310-30 loans totaled $2.1 million at June 30, 2016, compared to $2.8 million at September 30, 2015. During the three and nine month period ended June 30, 2016, loan pools accounted for under ASC 310-30 had a net reversal of provision of $0.4 million and $0.6 million, respectively, as a result of increases in expected cash flows. Net provision reversals for the three and nine month period ended June 30, 2015 totaled $0.6 million and $1.2 million, and were driven a result of increases in expected cash flows in the residential real estate pool.

For acquired loans not accounted for under ASC 310-20 (purchased non-credit impaired), the Company utilizes specific and collective reserve calculation methods similar to originated loans. The required ALLL for these loans is included in the individually evaluated for impairment bucket of the ALLL if the loan is rated substandard or worse, and in the collectively evaluated for impairment bucket for pass rated loans.

The reserve for unfunded loan commitments was $0.5 million at June 30, 2016 and $0.4 million at September 30, 2015 and is recorded in other liabilities on the consolidated balance sheets.

7. Accounting for Certain Loans Acquired with Deteriorated Credit Quality

In June 2010 and May 2016, the Company acquired certain loans that had deteriorated credit quality (ASC 310-30 loans). Loan accounting specific to these purchased credit impaired loans addresses differences between contractual cash flows expected to be collected from the initial investment in loans if those differences are attributable, at least in part, to credit quality. Several factors were considered when evaluating whether a loan was considered a purchased credit impaired loan, including the delinquency status of the loan, updated borrower credit status, geographic information, and updated loan-to-values (“LTV”). U.S. GAAP allows purchasers to aggregate purchased credit impaired loans acquired in the same fiscal quarter in one or more pools, provided that the loans have common risk characteristics. A pool is then accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows.

Loan pools are periodically reassessed to determine expected cash flows. In determining the expected cash flows, the timing of cash flows and prepayment assumptions for smaller, homogeneous loans are based on statistical models that take into account factors such as the loan interest rate, credit profile of the borrowers, the years in which the loans were originated, and whether the loans are fixed or variable rate loans. Prepayments may be assumed on large individual loans that consider similar prepayment factors listed above for smaller homogeneous loans. The re-assessment of purchased credit impaired loans resulted in the following changes in the accretable yield during the three and nine months ended June 30, 2016 and 2015 (in thousands):

	Three Months Ended June 30,						Nine Months Ended June 30,
	2016			2015			2016			2015
Balance at beginning of period	$	39,843		$	43,431		$	44,489		$	50,889
Acquisition	3,662			—			3,662			—
Accretion	(2,529		)	(3,240		)	(7,119		)	(11,249		)
Reclassification from (to) nonaccretable difference	—			7,736			(56		)	8,367
Disposals	—			(1,038		)	—			(1,118		)
Balance at end of period	$	40,976		$	46,889		$	40,976		$	46,889

The reclassification from nonaccretable difference noted in the table above represents instances where specific pools of loans are expected to perform better over the remaining lives of the loans than expected at the prior re-assessment date. The reclassification to nonaccretable difference noted in the table above represents instances where specific pools of loans are estimated to have a shortfall in the expected future cash flows compared to the contractual cash flows at the prior re-assessment date.

The following table provides purchased credit impaired loans at June 30, 2016 and September 30, 2015 (in thousands):

	June 30, 2016						September 30, 2015

2 Represents the book balance of loans acquired with deteriorated credit quality.

Due to improved cash flows of the purchased credit impaired loans, the reductions to allowance recognized on previous impairments were $0.4 million and $0.9 million for the three months ended June 30, 2016 and 2015, respectively and $0.6 million and $1.9 million for the nine months ended June 30, 2016 and 2015, respectively.

8. FDIC Indemnification Asset

Under the terms of the purchase and assumption agreement with the FDIC with regard to the TierOne Bank acquisition, the Company is reimbursed for a portion of the losses incurred on covered assets. As covered assets are resolved, whether it be through repayment, short sale of the underlying collateral, the foreclosure on or sale of collateral, or the sale or charge-off of loans or OREO, any differences between the carrying value of the covered assets versus the payments received during the resolution process, that are reimbursable by the FDIC, are recognized as reductions in the FDIC indemnification asset. Any gains or losses realized from the resolution of covered assets reduce or increase, respectively, the amount recoverable from the FDIC. The following table represents a summary of the activity related to the FDIC indemnification asset for the three and nine months ended June 30, 2016 and 2015 (in thousands):

	Three Months Ended June 30,						Nine Months Ended June 30,

Balance at end of period	$	11,706		$	16,979		$	11,706		$	16,979

The loss claims filed are subject to review, approval, and annual audits by the FDIC or its assigned agents for compliance with the terms in the loss sharing agreements. The non-commerical loss share agreement ends June 4, 2020.

9. Derivative Financial Instruments

In the normal course of business, the Company uses interest rate swaps to manage its interest rate risk and market risk in accommodating the needs of its customers. Also, the Company enters into interest rate lock commitments on mortgage loans to be held for sale, with corresponding forward sales contracts related to these interest rate lock commitments.

Derivative instruments are recognized as either assets or liabilities in the accompanying consolidated financial statements and are measured at fair value.

The following table summarizes the notional amounts and estimated fair values of the Company’s derivative instruments at June 30, 2016 and September 30, 2015 (in thousands):

	June 30, 2016
	Notional Amount		Balance Sheet Location	Positive Fair Value		Negative Fair Value
Derivatives not designated as hedging instruments:
Interest rate swaps	$	1,071,795	Liabilities	$	—	$	(91,066	)

Mortgage loan commitments	30,196		Assets	95		—
Mortgage loan forward sale contracts	36,655		Liabilities	—		(95		)

As with any financial instrument, derivative financial instruments have inherent risk including adverse changes in interest rates. The Company’s exposure to derivative credit risk is defined as the possibility of sustaining a loss due to the failure of the counterparty to perform in accordance with the terms of the contract. Credit risks associated with interest rate swaps are similar to those relating to

Notes to Consolidated Financial Statements (Unaudited)

traditional on-balance sheet financial instruments. The Company manages interest rate swap credit risk with the same standards and procedures applied to its commercial lending activities. Amounts due from swap counterparties to reclaim cash collateral under the interest rate swap master netting arrangements have not been offset against the derivative balances.

Credit-risk-related contingent features

The Company has agreements with its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well/adequately capitalized institution, then the counterparty has the right to terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of June 30, 2016, the termination value of derivatives in a net liability position related to these agreements was $93.4 million which includes accrued interest but excludes any adjustment fornonperformance risk. The Company has minimum collateral posting thresholds with its derivative counterparties and as of June 30, 2016, the Company had posted $101.6 million in eligible collateral.

The effect of derivatives on the consolidated statements of comprehensive income for the three and nine months ended June 30, 2016 and 2015 (in thousands) was as follows:

		Amount of Gain (Loss) Recognized in Income
		Three Months Ended June 30,						Nine Months Ended June 30,

Mortgage loan forward sale contracts	Noninterest income	(201		)	26			(253		)	(1		)

Netting of Derivatives

The Company has various financial assets and financial liabilities that are subject to enforceable master netting agreements or similar agreements. The Company has entered into an ISDA master netting arrangement with various swap counterparties. Under the terms of the master netting arrangements, all transactions between the Company and the counterparty constitute a single business relationship such that in the event of default, the non-defaulting party is entitled to set off claims and apply property held by that party in respect of any transaction against obligations owed. Any payments, deliveries, or other transfers may be applied against each other and netted.

The following tables (in thousands) present the Company's total gross derivative assets and liabilities at June 30, 2016 and September 30, 2015, which are adjusted on an aggregate basis, where applicable, to take into consideration the effects of legally enforceable master netting agreements for the net reported amount in the consolidated balance sheets. These amounts are offset on the consolidated balance sheets.

10. The Fair Value Option For Certain Loans

The Company has elected to measure certain long-term loans and written loan commitments at fair value to assist in managing the interest rate risk for longer-term loans. This fair value option was elected upon the origination of these loans. Interest income is recognized in the same manner as interest on non-fair value loans.

See Note 19 for additional disclosures regarding the fair value of the fair value option loans and written loan commitments.

Long-term loans and written loan commitments for which the fair value option has been elected had a net favorable difference between the aggregate fair value and the aggregate unpaid loan principal balance and written loan commitment amount of approximately $83.0 million and $47.8 million at June 30, 2016 and September 30, 2015, respectively. The total unpaid principal balance of these long-term loans was approximately $1.07 billion and $1.07 billion at June 30, 2016 and September 30, 2015, respectively. The fair value of these loans and written loan commitments is included in total loans in the consolidated balance sheets and are grouped with commercial non real estate, commercial real estate, and agricultural loans in Note 5. The fair value of these written loan commitments was not material at June 30, 2016 and September 30, 2015, respectively. As of June 30, 2016 and September 30, 2015, there were loans with a fair value of $9.0 million and $1.5 million, respectively, which were greater than 90 days past due or in nonaccrual status with an unpaid principal balance of $11.0 million and $1.7 million, respectively.

Changes in fair value for items for which the fair value option has been elected and the line items in which these changes are reported within the consolidated statements of comprehensive income are as follows for the three and nine months ended June 30, 2016 and 2015 (in thousands):

	For the Three Months Ended										For the Nine Months Ended
	June 30, 2016				June 30, 2015						June 30, 2016				June 30, 2015

For long-term loans and written loan commitments, $2.7 million and $0.0 million for the three months ended June 30, 2016 and 2015, respectively, and $2.3 million and $0.5 million for the nine months ended June 30, 2016 and 2015, respectively, of the total change in fair value is attributable to changes in specific credit risk. The gains or losses attributable to changes in instrument-specific credit risk were determined based on an assessment of existing market conditions and credit quality of the underlying loan for the specific portfolio of loans.

(1) Changes to carrying amounts are reported net of loan servicing income on the consolidated statements of comprehensive income for the periods presented.

Amortization of servicing rights is adjusted each quarter based upon analysis of portfolio attributes and factors, including an evaluation of historical prepayment activity and prospective industry consensus data. An independent third party is utilized to calculate the amortization and valuation based upon specific loan characteristics, prepayment speeds generated from a validation model utilizing both empirical and market derived data and discount rates. At June 30, 2016, the constant prepayment rates (CPR) used to calculate the amortization averaged 16.4%. For valuation purposes, an average discount rate of 11.6% was utilized at June 30, 2016. Based on the Company's analysis of mortgage servicing rights, a $0.2 million valuation reserve was recorded at June 30, 2016 and $0.0 million at June 30, 2015.

14. Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase generally mature overnight following the transaction date. Securities underlying the agreements had an amortized cost of approximately $161.8 million and $180.6 million and fair value of approximately $163.0 million and $181.6 million at June 30, 2016 and September 30, 2015, respectively. In most cases, the Company over-collateralizes the repurchase agreements at 102% of total funds borrowed to protect the purchaser from changes in market value.  Additionally, the Company utilizes held-in-custody procedures to ensure the securities sold under repurchase agreements are unencumbered. The following tables present the gross obligation by the class of collateral pledged and the remaining contractual maturity of the agreements at June 30, 2016 and September 30, 2015 (in thousands).

16. Subordinated Debentures and Subordinated Notes Payable

Junior Subordinated Deferrable Interest Debentures

The Company has caused seven trusts to be created (or assumed as part of the HF Financial and Sunstate Bank acquisitions) that have issued and outstanding 78,400 shares, $1,000 par value, of Company Obligated Mandatorily Redeemable Preferred Securities (the "Preferred Securities"). These seven trusts were established and exist for the sole purpose of issuing the Preferred Securities and investing the proceeds in junior subordinated deferrable interest debentures (the "Debentures") issued by the Company. The Debentures constitute the sole assets of the seven trusts. The Preferred Securities provide for cumulative cash distributions calculated at a rate based on three-month LIBOR plus a range from 1.48% to 3.35% adjusted quarterly. The Company may, at one or more times, defer interest payments on the Debentures for up to 20 consecutive quarters following suspension of dividends on all capital stock, but not beyond the respective maturity date. At the end of any deferral period, all accumulated and unpaid interest must be paid. The Debentures have redemption dates ranging from January 7, 2033 to October 1, 2037; however, the Company has the option to shorten the respective maturity date for all seven Preferred Securities as the call option date has passed. Holders of the Preferred Securities have no voting rights. The Preferred Securities are unsecured and rank junior in priority of the payment to all of the Company's indebtedness and senior to the Company's common and preferred stock. The trusts’ ability to pay amounts due on the Preferred Securities is solely dependent upon the Company making payment on the related Debentures. The Company’s obligation under the Debentures and relevant trust agreements constitute a full, irrevocable, and unconditional guarantee on a subordinated basis by it of the obligations of the trusts under the Preferred Securities.

For regulatory purposes the Debentures qualify as elements of capital. $77.1 million and $56.1 million of Debentures were eligible for treatment as Tier 1 capital, respectively, as of June 30, 2016 and 2015.

Relating to the trusts, the Company held as assets $2.5 million and $1.7 million in common shares at June 30, 2016 and 2015, respectively, which are included in other assets on the consolidated balance sheets.

Subordinated Notes Payable

In 2015, the Company issued $35.0 million of 4.875% fixed-to-floating rate subordinated notes that mature on August 15, 2025 through a private placement. The notes, which qualify as Tier 2 capital under capital rules in effect at June 30, 2016, have an interest rate of 4.875% per annum, payable semi-annually on each February 15 and August 15, which commenced on February 15, 2016 until August 15, 2020. From August 15, 2020, to but excluding the maturity date or date of earlier redemption, the notes will bear interest at a rate per annum equal to to three-month LIBOR for the related interest period plus 3.15%, payable quarterly on each November 15, February 15, April 15 and August 15. The notes are subordinated in right of payment to all of the Company's senior indebtedness and effectively subordinated to all existing and future debt and all other liabilities of the Company's subsidiary bank. The Company may elect to redeem the notes (subject to regulatory approval), in whole or in part, on any early redemption date which is any interest payment date on or after August 15, 2020 at a redemption price equal to 100% of the principal amount plus any accrued and unpaid interest. Other than on an early redemption date, the notes cannot be accelerated except in the event of bankruptcy or the occurrence of certain other events of bankruptcy, insolvency or reorganization. Proceeds from the private placement of subordinated notes repaid outstanding subordinated debt.

17. Profit-Sharing and Defined Benefit Plans

Profit Sharing Plan

The Company participates in a multiple employer 401(k) profit sharing plan (the Plan). All employees are eligible to participate, beginning with the first day of the month coincident with or immediately following the completion of one year of service and having reached the age of 21. In addition to employee contributions, the Company may contribute discretionary amounts for eligible participants. Contribution rates for participating employees must be equal. The Company contributed $1.2 million and $1.1 million to the Plan for the three months ended June 30, 2016 and 2015, respectively and $3.2 million and $2.9 million for the nine months ended June 30, 2016 and 2015, respectively.

Defined Benefit Plan

The Company acquired a noncontributory (cash balance) defined benefit pension plan from HF Financial which covers employees of HF Financial and its wholly-owned subsidiaries. Effective July 1, 2015, the Company froze the plan which eliminates future contributions for qualified individuals. The plan has not been terminated, so the plan continues to exist with related benefit obligations and plan assets for those vested within the plan.

18. Stock-Based Compensation

On September 26, 2014, the Board of Directors adopted, and on October 10, 2014, NAB, at that time our controlling shareholder, approved the Great Western Bancorp, Inc. 2014 Omnibus Incentive Compensation Plan (the “2014 Plan”), the Great Western Bancorp, Inc. 2014 Non-Employee Director Plan (the “2014 Director Plan”), and the Great Western Bancorp, Inc. Executive Incentive Compensation Plan (the “Bonus Plan”), collectively ("the Plans"), which provide for the issuance of restricted share units and performance based share units to certain officers, employees and directors of the Company. The Plans were primarily established to enhance the Company’s ability to attract, retain and motivate employees. The Company’s Board of Directors, the Compensation Committee of the Board of Directors ("Compensation Committee"), or executive management upon delegation of the Compensation Committee has exclusive authority to select the employees and others, including directors, to receive the awards and to establish the terms and conditions of each award made pursuant to the Company’s stock-based compensation plans.

Stock units issued under the Company’s restricted and performance based stock plans may not be sold or otherwise transferred until the vesting period (typically 3 years) has been met and/or performance objectives have been obtained. During the vesting periods, participants do not have voting rights and dividends are accumulated until the time upon which the award vests. Upon specified events, as defined in the Plans, stock unit awards that have not vested and/or performance hurdles that have not been met will be forfeited.

Based on the substantive terms of each award, restricted and performance-based awards are classified as equity awards and accounted for under the Treasury method. The fair value of equity-classified awards is based on the market price of the stock on the measurement date and is amortized as compensation expense on a straight-line basis over the vesting or performance period.

Stock based compensation is recognized based on the number of awards that are ultimately expected to vest. Forfeitures are estimated based on historical turnover experience of qualified employees. For performance-based stock awards, an estimate is made of the number of shares expected to vest as a result of actual performance against the performance targets to determine the amount of compensation expense to be recognized. The estimate is reevaluated quarterly and total compensation expense is adjusted for any change in the current period. Stock-based compensation expense is included in salaries and employee benefits expense in the consolidated statements of comprehensive income. For the three months ended June 30, 2016 and 2015, stock compensation expense was $0.9 million and $0.3 million, respectively. For the nine months ended June 30, 2016 and 2015, stock compensation expense was $2.7 million and $1.0 million, respectively. Related income tax benefits recognized were $0.3 million and $0.1 million for the three months ended June 30, 2016 and 2015, respectively and $1.0 million and $0.4 million for the nine months ended June 30, 2016 and 2015, respectively.

The number of performance shares granted is reflected in the above table at the 100% target performance level. The actual performance-based award payouts will vary based on the achievement of the pre-established targets and can range from 0% to 150% of the target amount. The outstanding number of performance shares reflected in the table represents the number of shares expected to be awarded based on estimated achievement of the goals as of June 30, 2016. The maximum number of performance-based shares that could be issued if performance is attained at 150% of target based on the grants made to date was approximately 359,853 shares at June 30, 2016.

As of June 30, 2016, there was $4.9 million of unrecognized compensation cost related to nonvested restricted stock awards expected to be recognized over a period of 2.4 years. The fair value of the vested, but not issued stock awards at June 30, 2016, was $0.8 million.

19. Fair Value Measurements

The Company measures, monitors and discloses certain of its assets and liabilities on a fair value basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value guidance also establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance describes three levels of inputs that may be used to measure fair value are as follows:

Level 1    Quoted prices in active markets for identical assets or liabilities

Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities

Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities

- 48-

GREAT WESTERN BANCORP, INC.

Notes to Consolidated Financial Statements (Unaudited)

Level 1 inputs are considered to be the most transparent and reliable and Level 3 inputs are considered to be the least transparent and reliable. The Company assumes the use of the principal market to conduct a transaction of each particular asset or liability being measured and then considers the assumptions that market participants would use when pricing the asset or liability. Whenever possible, the Company first looks for quoted prices for identical assets or liabilities in active markets (Level 1 inputs) to value each asset or liability. However, when inputs from identical assets or liabilities on active markets are not available, the Company utilizes market observable data for similar assets and liabilities. The Company maximizes the use of observable inputs and limits the use of unobservable inputs to occasions when observable inputs are not available. The need to use unobservable inputs generally results from the lack of market liquidity of the actual financial instrument or of the underlying collateral. Although in some instances, third party price indications may be available, limited trading activity can challenge the observability of these quotations.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Following is a description of the valuation methodologies and inputs used for assets and liabilities measured at fair value on a recurring basis and recognized in the accompanying consolidated balance sheets, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy.

Securities Available for Sale

Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include U.S. Treasury securities and U.S. Agency securities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows and classified as Level 2 securities. Level 2 securities include agency mortgage-backed, states and political subdivisions, corporate debt, and other securities. Where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy.

Interest Rate Swaps and Loans

Interest rate swaps are valued by the Company's Swap Dealers using LIBOR rates. The fair value of loans accounted for under the fair value option represents the net carrying value of the loan, plus the equal and opposite amount of the value of the swap needed to hedge the interest rate risk and an adjustment for credit risk based on our assessment of existing market conditions for the specific portfolio of loans. This is used due to the strict prepayment penalties put in the loan terms to cover the cost of exiting the hedge of the loans in the case of early prepayment or termination. The adjustment for credit risk on loans accounted for under the fair value option is not significant to the overall fair value of the loans. The fair values estimated by the Company's Swap Dealers use interest rates that are observable or that can be corroborated by observable market data and, therefore, are classified within Level 2 of the valuation hierarchy. The Company is required to post cash collateral to swap counterparties for interest rate derivative contracts that are in a liability position, thus a credit risk adjustment on interest rate swaps is not warranted.

Cash Value of Life Insurance

Fair value is equal to the cash surrender value of the life insurance policies.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Following is a description of the valuation methodologies used for assets and liabilities measured at fair value on a nonrecurring basis and recognized in the accompanying consolidated balance sheets, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy.

Impaired Loans (Collateral Dependent)

Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured for impairment. Allowable methods for estimating fair value include using the fair value of the collateral for collateral dependent loans or, where a loan is determined not to be collateral dependent, using the discounted cash flow method.

If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of the impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor, if necessary, to the appraised value and including costs to sell. Because many of these inputs are not observable, the measurements are classified as Level 3.

Other Real Estate Owned (OREO)

Other real estate owned consists of loan collateral that has been repossessed through foreclosure. This collateral is comprised of commercial and residential real estate. OREO is recorded initially at fair value of the collateral less estimated selling costs. Subsequent to foreclosure, valuations are updated periodically, and the assets may be marked down further to fair value less selling costs, reflecting a valuation allowance. Fair value measurements may be based upon appraisals, third-party price opinions, or internally developed pricing methods. These measurements are classified as Level 3.

Mortgage Loans Held for Sale

Fair value of mortgage loans held for sale is based on either quoted prices for the same or similar loans, or values obtained from third parties, or are estimated for portfolios of loans with similar financial characteristics and are therefore considered a Level 2 valuation.

Loan Servicing Rights

Fair value is determined at a tranche level, based on market prices for comparable mortgage servicing contracts (Level 3), when available, or alternatively based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model utilizes interest rate, prepayment speed, and default rate assumptions that market participants would use in estimating future net servicing income and that can be validated against market data (Level 3).

The following tables present the fair value measurement of assets and liabilities measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at June 30, 2016 and September 30, 2015 (in thousands):

	Fair Value		Level 1		Level 2		Level 3
As of June 30, 2016
Other real estate owned	$	3,985	$	—	$	—	$	3,985
Impaired loans	160,151		—		—		160,151

Disclosures about Fair Value of Financial Instruments

For financial instruments that have quoted market prices, those quotes are used to determine fair value. Financial instruments that have no defined maturity, have a remaining maturity of 180 days or less, or reprice frequently to a market rate are assumed to have a fair value that approximates carrying value, after taking into consideration any applicable credit risk. If no market quotes are available, financial instruments are valued by discounting the expected cash flows using an estimated current market interest rate for the financial instrument.

The short maturity of the Company’s assets and liabilities results in having a significant number of financial instruments whose fair value equals or closely approximates carrying value. Such financial instruments are reported in the following consolidated balance sheet categories: cash and due from banks, securities sold under agreements to repurchase, and accrued interest.

Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments include premises and equipment, deferred income taxes, goodwill, and core deposit and other intangibles. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

Off-balance sheet instruments (commitments to extend credit and standby letters of credit) are generally short-term and at variable rates. Therefore, both the carrying amount and the estimated fair value associated with these instruments are immaterial. Fair values for balance sheet instruments as of June 30, 2016 and September 30, 2015, are as follows (in thousands):

		June 30, 2016				September 30, 2015
	Level in Fair Value Hierarchy	Carrying Amount		Fair Value		Carrying Amount		Fair Value

Notes to Consolidated Financial Statements (Unaudited)

The following methods and assumptions were used in estimating the fair value of financial instruments that were not previously disclosed:

Cash and cash due from banks: Due to the short term nature of cash and cash equivalents, the estimated fair value is equal to the carrying value and they are categorized as a Level 1 fair value measurement.

Loans, net excluding fair valued loans and loans held for sale: The fair value of the loan portfolio is estimated using observable inputs including estimated cash flows, and discount rates based on interest rates currently being offered for loans with similar terms, to borrowers of similar credit quality. Loans held for investment are categorized as a Level 3 fair value measurement.

Accrued interest receivable: Due to the nature of accrued interest receivable, the estimated fair value is equal to the carrying value and they are categorized as a Level 2 fair value measurement.

Federal Home Loan Bank stock: The carrying amount of FHLB stock approximates its fair value as it can only be redeemed with the FHLB at par value. Federal Home Loan Bank stock has been categorized as a Level 2 fair value measurement.

Deposits: The estimated fair value of deposits with no stated maturity, such as non-interest bearing demand deposits, savings, NOW, and money market accounts, is equal to the amount payable on demand. The fair value of interest-bearing time deposits is based on the discounted value of contractual cash flows of such deposits, taking into account the option for early withdrawal. The discount rate is estimated using the rates offered by the Company, at the respective measurement dates, for deposits of similar maturities. Deposits have been categorized as a Level 2 fair value measurement.

FHLB advances and other borrowings: The fair value of FHLB advances and other borrowings is estimated using discounted cash flow analysis, based on current incremental borrowing rates for similar types of borrowing arrangements. In the absence of a reasonably precise methodology to determine the fair value of the credit agreement, carrying value has been used to represent fair value. FHLB advances and other borrowings have been categorized as a Level 2 fair value measurement.

Securities sold under repurchase agreements: The Company’s repurchase agreements are overnight transactions that mature the day after the transaction, and as a result of this short-term nature, the estimated fair value equals the carrying value. Securities sold under repurchase agreements have been categorized as a Level 2 fair value measurement.

Accrued interest payable: Due to the nature of accrued interest payable, the estimated fair value is equal to the carrying value and they are categorized as a Level 2 fair value measurement.

Subordinated Debentures and Subordinated Notes Payable: The fair value of subordinated debentures and subordinated notes payable is estimated using discounted cash flow analysis, based on current incremental debt rates. Subordinated debentures and subordinated notes payable have been categorized as a Level 2 fair value measurement.

20. Earnings per Share

Basic earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period, excluding outstanding non-vested restricted stock awards. Diluted earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding determined for the basic earnings per share calculation plus the dilutive effect of stock compensation using the treasury stock method.

Overview

We are a full-service regional bank holding company focused on relationship-based business and agribusiness banking. We serve our customers through 178 branches in attractive markets in nine states: South Dakota, Iowa, Nebraska, North Dakota, Minnesota, Colorado, Arizona, Kansas and Missouri. On June 24, 2016, we closed one branch location within our banking footprint and on July 11, 2016, we opened one branch location within our banking footprint. We do not believe these changes will have a material impact on our customers or on our business as a whole.

Our acquisition of HF Financial closed on May 16, 2016, for total consideration of $142.0 million, which included stock consideration valued at $107.5 million and cash consideration of $34.5 million. The acquisition resulted in an increase in total assets with an acquired value of $1.12 billion, including loans with a fair value of $863.7 million, and deposits of $863.1 million. We recorded $40.7 million of goodwill and $7.9 million of other intangible assets in conjunction with the acquisition. We anticipate increased revenues from the acquisition due to the addition of 23 branch locations in three states, including an expanded presence in eastern North Dakota and Minnesota, as well as cost synergies to be recognized in future periods through the elimination of redundant operations.

Our bank was established more than 80 years ago and we have achieved strong market positions by developing and maintaining extensive local relationships in the communities we serve. By leveraging our business and agribusiness focus, presence in attractive markets, highly efficient operating model and robust approach to risk management, we have achieved significant and profitable growth—both organically and through disciplined acquisitions. We provide financial results based on a fiscal year ending September 30 as a single reportable segment.

The principal sources of our revenues and cash flows are: (i) interest and fees earned on loans made or held by our bank; (ii)

interest on fixed income investments held by our bank; (iii) fees on wealth management services; (iv) service charges on deposit

accounts maintained at our bank; (v) mortgage banking income; and (vi) merchant and card fees. Our principal expenses are: (i) interest expense on deposit accounts and other borrowings; (ii) salaries and employee benefits; (iii) data processing costs primarily associated with maintaining our bank's loan and deposit functions; (iv) occupancy expenses for maintaining our bank's facilities; (v) professional fees; (vi) communications; (vii) advertising; (viii) FDIC insurance assessments; and (ix) other real estate owned expenses. The largest component contributing to our net income is net interest income, which is the difference between interest earned on earning assets (primarily loans and investments) and interest paid on interest bearing liabilities (primarily deposit accounts and other borrowings). One of management's principal functions is to manage the spread between interest earned on earning assets and

- 55-

interest paid on interest bearing liabilities in an effort to maximize net interest income while maintaining an appropriate level of interest rate risk.

Net income was $26.4 million for the third quarter of fiscal year 2016, while adjusted net income excluding the effect of one-time acquisition expenses of $12.2 million related to the HF Financial acquisition was $33.9 million, an increase of $5.1 million, or 17.6% compared to the third quarter of fiscal year 2015. Fiscal year-to-date net income was $87.5 million, while adjusted net income was $95.5 million compared to $75.3 million for the same period of fiscal year 2015. For more information on our adjusted net income, including a reconciliation to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" section.

Our efficiency ratio was 58.8% for the third quarter of fiscal year 2016, compared to 46.4% for the same quarter of fiscal year 2015. The increase was driven primarily by one-time acquisition expenses of $12.2 million related to the HF Financial acquisition. Our efficiency ratio remained strong at 50.0% on a fiscal year-to-date basis although that is also elevated by $12.9 million of one-time fiscal year-to-date acquisition expenses. For more information on our efficiency ratio, including a reconciliation to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" section.

Net interest margin was 3.95%, 3.99% and 3.95%, respectively, for the quarters ended June 30, 2016, March 31, 2016 and June 30, 2015 and 3.97% and 3.92%, respectively for the nine months ended June 30, 2016 and June 30, 2015. Adjusted net interest margin, which reflects the realized gain (loss) on interest rate swaps, was 3.74%, 3.75% and 3.70%, respectively, and 3.74% and 3.67%, respectively, for the same periods. We believe our adjusted net interest margin is more representative of our underlying performance and is the measure we use internally to evaluate our results. Net interest margin and adjusted net interest marginwere stable and 4 basis points higher, respectively, compared to the same quarter of fiscal year 2015, primarily as a result of asset growth and mix, including the growth in average loans as a proportion of interest earning assets and a lower average balance of cash and due from banks. Total cost of deposits was 1 basis point higher in the current quarter compared to the same quarter of fiscal year 2015. Net interest margin and adjusted net interest margin were 5 and 7 basis points higher, respectively, compared to the nine months ended June 30, 2015, primarily as a result of changes in asset mix with loan balances making up a higher proportion of average interest earning assets. For more information on our adjusted net interest margin, including a reconciliation to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" section.

Net income for the quarter represents earnings per diluted common share and adjusted earnings per diluted common share of $0.46 and $0.59, respectively, compared to $0.50 in the comparable period, and $1.56 and $1.71, respectively, fiscal year-to-date compared to $1.30 for the same period in fiscal year 2015. Adjusted earnings per diluted common share equals earnings per diluted share for both comparable periods ended June 30, 2015. On July 28, 2016, our board of directors declared a dividend of $0.14 per common share payable on August 24, 2016 to stockholders of record as of the close of business on August 12, 2016.

During the quarter we experienced both loan and deposit growth. Total loans increased $1.05 billion, or 13.9%, including $863.7 million of loans at fair value acquired in the HF Financial acquisition, to $8.61 billion at June 30, 2016, bringing fiscal year-to-date growth to $1.28 billion, or 17.5%. Excluding the acquired loans, fiscal year-to-date growth was $418.1 million, or 5.7%. The net organic growth during the quarter of $185.4 million was primarily driven by $97.0 million of growth in commercial non-real estate ("C&I") loans and $87.2 million of growth in commercial real estate ("CRE") loans. Loans acquired in the HF Financial acquisition were headlined by $491.8 million of CRE loans and $189.8 million of agriculture loans. Deposits increased to $8.48 billion at June 30, 2016, an increase of $767.5 million, or 10.0% during the quarter, which included $863.1 million of deposits at fair value acquired in the HF Financial acquisition. The net organic deposit runoff during the quarter was driven by a small number of larger commercial brokered depositors exiting the bank and seasonal consumer withdrawals, partially offset by growth in other commercial and public funds deposits. Excluding the deposits acquired, the fiscal year-to-date growth was $230.0 million, or 3.1%, compared to September 30, 2015.

At June 30, 2016, loans graded "Watch" were $395.9 million, an increase of $85.5 million, or 27.6%, compared to September 30, 2015, and loans graded "Substandard" were $237.6 million, an increase of $54.0 million, or 29.4%, over the same period. Loans acquired in the HF Financial acquisition contributed $99.4 million of the increase in "Watch" loans and $18.6 million of the increase in "Substandard" loans, meaning the net change excluding HF Financial loans was a reduction to "Watch" and a moderate increase to "Substandard" loans. The levels of acquired loans in these categories is consistent with expectations derived from due diligence and was considered in the purchase price paid for HF Financial and in the valuation of the acquired loans.

Nonaccrual loans, including ASC 310-30 loans, were $108.2 million as of June 30, 2016, with $4.2 million of the balance covered by FDIC loss-sharing arrangements. Total nonaccrual loans increased by $53.2 million during the quarter and increased by $39.9 million compared to September 30, 2015. The increase in nonaccrual loans was primarily driven by the deterioration of a small number of lending relationships, which have been closely monitored and managed for a number of quarters, and had already been classified as "Substandard" loans. Total OREO balances were $11.7 million as of June 30, 2016, a decrease of $0.5 million, or 4.1%, compared to prior quarter and a decrease of $4.2 million, or 26.4%, compared to September 30, 2015.

Provision for loan and lease losses was $5.4 million for the quarter ended June 30, 2016, compared to $4.4 million in the same quarter of fiscal year 2015. Provision for loan and lease losses was $11.9 million and $17.4 million for the nine months ended June 30, 2016 and 2015, respectively. Net charge-offs for the third quarter of fiscal year 2016 were $3.0 million compared to $0.9 million for the same quarter of fiscal year 2015 and $4.8 million and $9.0 million for the nine months ended June 30, 2016 and 2015, respectively. The ratio of ALLL to total loans was 0.75% at June 30, 2016, down from 0.78% at September 30, 2015 as a result of loan accounting attributable to the HF Financial acquisition. During the third quarter of 2016, acquired loans were added in the HF Financial acquisition with no carryover of the related ALLL. The balance of the ALLL increased from $57.2 million at September 30, 2015 to $64.2 million at June 30, 2016.

Our capital position is strong and stable, with Tier 1 capital, total capital and Tier 1 leverage ratios of 10.9%, 12.0% and 10.0%, respectively, at June 30, 2016, compared to 10.9%, 12.1% and 9.1%, respectively, at September 30, 2015. In addition, our Common Equity Tier 1 ratio was 10.0% at June 30, 2016 and 10.1% at September 30, 2015. Our tangible common equity to tangible assets ratio was 8.3% at June 30, 2016 and 8.3% at September 30, 2015. For more information on our tangible common equity to tangible assets ratio, including a reconciliation to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" section.

Key Factors Affecting Our Business and Financial Statements

As discussed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2015, our business and results of operations are impacted by several key factors, including economic conditions, interest rates, asset quality and loss-sharing arrangements, banking laws and regulations, competition, our operational efficiency, goodwill and amortization of other intangible assets and accounting for loans and interest rate swaps at fair value.  There have been no material changes to these factors except as otherwise supplemented within this Quarterly Report on Form 10-Q for the nine months ended June 30, 2016 and within our Quarterly Report on Form 10-Q for the three and six months ended December 31,2015 and March 31, 2016, respectively.

Net interest income was $93.6 million for the third quarter of fiscal year 2016 compared to $86.2 million for the same quarter in fiscal year 2015, an increase of 8.5%. The increase was primarily attributable to higher loan interest income driven by 12.7% growth in average loans outstanding between the periods. Net interest income for the third quarter of fiscal year 2016 included inorganic growth from the HF acquisition, $1.8 million of accretion income from the HF Financial ASC 310-20 loans partially offset by $1.5 million of accrued interest charged off. Net interest margin was 3.95% for the third quarter of fiscal year 2016, compared with 3.95% for the same period in fiscal year 2015. Adjusted net interest margin was 3.74% and 3.70%, respectively, for the same periods. Net interest margin and adjusted net interest marginwere stable and 4 basis points higher, respectively, compared to the same quarter of fiscal year 2015, with the increase in adjusted net interest margin due to changes in asset mix and period-over-period increase in LIBOR rates which reduced the net cost of pay fixed, receive floating interest rate swaps the Company utilizes related to certain fixed rate loans. Total cost of deposits was 1 basis point higher in the current quarter compared to the same quarter of fiscal year 2015. For more information on our adjusted net interest margin and adjusted net interest income, including a reconciliation of each to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" section.

Net interest income was $269.5 million for the first nine months of fiscal year 2016 compared to $252.9 million for the same period in fiscal year 2015, an increase of 6.6%. The increase was driven primarily by higher loan interest income attributable to loan growth and the HF Financial acquisition as noted above. Net interest margin was 3.97% for the first nine months of fiscal year 2016, compared with 3.92% for the same period in fiscal year 2015. Adjusted net interest margin was 3.74% and 3.67%, respectively, for the same periods. Net interest margin and adjusted net interest marginwere 5 and 7 basis points higher, respectively, compared to the same quarter of fiscal year 2015, primarily as a result of changes in asset mix with loan balances making up a higher proportion of average interest earning assets. On a sequential quarter basis, the yield on total loans declined 6 basis points to 4.79% while the cost of deposits remained stable at 0.32%, the yield on investment securities increased by 4 basis points and cost of FHLB borrowings declined 10 basis points to 0.66%.

The following table presents the distribution of average assets, liabilities and equity, interest income and resulting yields on average interest-earning assets, and interest expense and rates on average interest-bearing liabilities for the current and comparable three and nine month periods. Loans on nonaccrual status that had interest accrued as of the date of nonaccrual is immediately reversed as a reduction to interest income, while any interest subsequently recovered is recorded in the period of recovery. Tax-exempt loans and securities, totaling $673.3 million at June 30, 2016 and $556.8 million at June 30, 2015, are typically entered at lower interest rate arrangements than comparable non-exempt loans and securities. The amount of interest income reflected below has been adjusted to include the amount of tax benefit realized in the period and as such is presented on a fully-tax equivalent basis, the calculation of which is outlined in the discussion of non-GAAP items later in this section. ASC 310-30 loans represent loans accounted for in accordance with ASC 310-30 Accounting for Purchased Loans that were credit impaired at the time we acquired them. Non ASC 310-30 loans represent loans we have originated and loans we have acquired that were not credit impaired at the time we acquired them.

Total interest and dividend income consists primarily of interest income on loans and interest and dividend income on our investment portfolio. Total interest and dividend income was $102.1 million for the third quarter of fiscal year 2016, compared to $93.6 million for the same period of fiscal year 2015, an increase of 9.1%. Total interest and dividend income was $293.5 million for the first nine months of fiscal year 2016, compared to $275.5 million for the same period of fiscal year 2015, an increase of 6.6%.Significant components of interest and dividend income are described in further detail below.

Loans. Interest income on all loans increased to $95.7 million in third quarter of fiscal year 2016 from $86.9 million in the third quarter of fiscal year 2015, an increase of 10.0% between the two periods. Average net loan balances for the third quarter of fiscal year 2016 were $8.02 billion, representing a 12.7%increase compared to the same period in fiscal year 2015. The net loan growth during the quarter was primarily driven by CRE, C&I and agriculture loans. The largest contributor to growth during the third quarter of fiscal year 2016 was CRE which was distributed across the non-owner-occupied, owner-occupied, construction and development and multi-family residential real estate subsegments across a diverse range of projects with a continued focus on limiting exposure to land development and other projects that are speculative in nature. Interest income on ASC 310-30 loans increased $0.2 million between the two periods, primarily driven by the HF Financial acquisition. Interest income on acquired loans accounted for under ASC 310-20 increased $1.7 million between the two periods, primarily driven by accretion recognized on the HF Financial acquired loans. This increase was partially offset by $1.5 million of accrued interest charged off.

Interest income on all loans increased to $274.7 million in the first nine months of fiscal year 2016 from $256.8 million in the same period of fiscal year 2015, an increase of 7.0% between the two periods. Average net loan balances for the first nine months of fiscal year 2016 were $7.60 billion, representing a 9.3%increase compared to the same period in fiscal year 2015. Growth was again focused in the CRE segment of the portfolio ($319.5 million or 11.2% growth for the first nine months of fiscal year 2016 excluding HF Financial acquired CRE loans).

Our yield on loans is affected by market interest rates, the level of adjustable-rate loan indices, interest rate floors and caps, customer repayment activity, the level of loans held for sale, portfolio mix, and the level of nonaccrual loans. The average tax equivalent yield on non ASC 310-30 loans was 4.77% for the third quarter of fiscal year 2016, a decrease of 9 basis points compared to 4.86% for the same period in fiscal year 2015. Adjusted for the current realized gain (loss) on derivatives we use to manage interest rate risk on certain of our loans at fair value, which we believe represents the underlying economics of the transactions, the adjusted yield on non ASC 310-30 loans was 4.52% for the current quarter, a 3 basis point decrease compared to the third quarter of fiscal year 2015. These decreases continue to be attributable to the competitive interest rate environment for high quality commercial and agricultural credits across our footprint and a prolonged rate cycle with very low short-term rates. We have begun to benefit from a period-over-period increase in LIBOR rates which has reduced the net cost of pay fixed, receive floating interest rate swaps the Company utilizes related to certain fixed rate loans. The average tax equivalent yield on non ASC 310-30 loans was 4.81% for the first nine months of fiscal year 2016, a decrease of 9 basis points compared to 4.90% for the same period in fiscal year 2015 with the decrease driven by the same factors noted above.

The average duration, net of interest rate swaps, of the loan portfolio was a relatively short 1.3 years as of June 30, 2016. Approximately 50%, or $4.26 billion, of the portfolio is comprised of fixed rate loans, of which $1.16 billion of loans are fixed rate loans with an original term of 5 years or greater for which we have entered into equal and offsetting fixed-to-floating interest rate swaps. These loans effectively behave as floating rate loans. Of the remaining floating rate loans in the portfolio, approximately 59% are indexed to Wall Street Journal Prime, 22% to 5-year Treasuries and the balance to various other indices. These loans have an average interest rate floor 72 bps above market rates.

Loan-related fee income of $3.0 million is included interest income for the third quarter of fiscal year 2016 and $2.2 million for the same period in fiscal year 2015. Loan-related fee income of $7.8 million is included in interest income for the first nine months of fiscal year 2016 compared to $6.8 million for the same period in fiscal year 2015. In addition, certain fees collected at loan origination are considered to be a component of yield on the underlying loans and are deferred and recognized into income over the life of the loans. Amortization related to the FDIC indemnification assets of $1.0 million and $1.8 million for the third quarter of fiscal years 2016 and 2015, respectively, and $2.9 million and $6.3 million for the first nine months of fiscal years 2016 and 2015, respectively, is included as a reduction to interest income.

Investment Portfolio. The carrying value of investment securities and FHLB stock was $1.41 billion as of June 30, 2016. Interest and dividend income on investments includes income earned on investment securities and FHLB stock. Interest and dividend income on investments decreased by 3.1% to $6.3 million in the third quarter of fiscal year 2016 from $6.5 million in the third quarter of fiscal year 2015, driven by an decrease in average balances partially offset by a yield increase from 1.81% to 1.84% over the same period. Interest and dividend income on investments increased by 2.4% to $18.5 million in the first nine months of fiscal year 2016 from $18.1 million in the same period of fiscal year 2015, driven by an increase in average balances and a yield increase from 1.76% to 1.82% over the same period.

The weighted average life of the portfolio was 3.0 years and 3.1 years at June 30, 2016 and September 30, 2015, respectively.Average investments represented 14.4% and 16.4% of total average interest-earning assets for third quarters of fiscal years 2016 and 2015, respectively, and 15.0% and 15.9% for the first nine months of fiscal year 2016 and 2015, respectively.

Interest Expense

The following tables present interest expense for the periods ended June 30, 2016 and 2015:

	Three months ended June 30,
	2016		2015
	(dollars in thousands)
Interest expense:
Deposits	$	6,451	$	5,776
Securities sold under agreements to repurchase	124		134
FHLB advances and other borrowings	986		867
Related party notes payable	—		233
Subordinated debentures and subordinated notes payable	976		330
Total interest expense	$	8,537	$	7,340

	Nine months ended June 30,
	2016		2015
	(dollars in thousands)
Interest expense:
Deposits	$	18,145	$	17,775
Securities sold under agreements to repurchase	395		430
FHLB advances and other borrowings	2,831		2,706
Related party notes payable	—		692
Subordinated debentures and subordinated notes payable	2,662		985
Total interest expense	$	24,033	$	22,588

Total interest expense increased to $8.5 million in the third quarter of fiscal year 2016 from $7.3 million in the same quarter in fiscal year 2015, an increase of 16.3%, mostly due to an increase in interest expense on subordinated debt. The average cost of total interest-bearing liabilities was 0.38% for the third quarter of fiscal year 2016, compared to 0.36% for the same period in fiscal year 2015. Total interest expense increased to $24.0 million for the first nine months of fiscal year 2016 from $22.6 million in the same period in fiscal year 2015, an increase of 6.4%, mostly due to an increase in interest expense on subordinated debt. We issued $35.0 million of subordinated notes in July 2015 at an interest rate of 4.875% per annum, and used the proceeds and other cash to pay off lower-cost borrowing from our former parent. The average cost of total interest-bearing liabilities was 0.38% for the first nine months of fiscal year 2016, compared to 0.37% for the same period in fiscal year 2015. Significant components of interest expense are described in further detail below.

Deposits. Interest expense on deposits, consisting of checking accounts, MMDAs, NOW accounts, savings accounts and CDs, was $6.5 million and $5.8 million for the third quarter of fiscal year 2016 and 2015, respectively. Average deposit balances were $8.07 billion and $7.48 billion, respectively, for the same periods. The cost of deposits increased to 0.32% in the third quarter of fiscal year 2016 from 0.31% in the comparable quarter. Interest expense on deposits was $18.1 million for the first nine months of fiscal year 2016 compared with $17.8 million in the same period in fiscal year 2015, a increase of $0.4 million, or 2.1%. Average deposit balances were $7.72 billion and $7.37 billion, respectively, for the same periods. The cost of deposits declined to 0.31% in the first nine months of fiscal year 2016 from 0.32% in the same period in fiscal year 2015.

Average non-interest-bearing demand account balances comprised 18.5% of average total deposits for the current quarter, compared with 17.6% for the comparable quarter. Total average other liquid accounts, consisting of money market and savings accounts, increased to 64.9% of total average deposits for the current quarter, compared to 62.4% of total average deposits for the comparable quarter, while CD accounts represented 16.6% of average total deposits in the current quarter, compared to 20.1% in the comparable quarter. These trends in the composition of our deposit portfolio represent a continuation of our strategy over the last four

fiscal years to move away from more costly CD accounts toward more cost-effective transaction accounts as well as our focus on gathering business deposits, which are typically transaction accounts by nature. This transition, as well as continued low benchmark interest rates, have driven a significant decrease in our cost of deposits over that time frame.

FHLB Advances and Other Borrowings. Interest expense on FHLB advances and other borrowings was $1.0 million for the third quarter of fiscal year 2016 and $0.9 million for the comparable quarter in 2015, reflecting a weighted average cost of 0.66% for both three month periods ended June 30, 2016 and 2015. Our average balance for FHLB advances and other borrowings increased to $600.5 million in the current quarter compared to $523.8 million in the comparable quarter. Interest expense on FHLB advances and other borrowings was $2.8 million and $2.7 million for the first nine months of fiscal year 2016 and the same period in fiscal year 2015, respectively, representing a weighted average cost of 0.72% and 0.67%, respectively. The amount of FHLB advances outstanding has increased to fund loan growth and also contributed to a higher cash balance at June 30, 2016. Average FHLB advances and other borrowings as a proportion of total average interest-bearing liabilities were 6.7% for the current quarter compared to 6.3% for the comparable quarter. The average rate paid on FHLB advances is impacted by market rates and the various terms and repricing frequency of the specific outstanding borrowings in each year. Our total outstanding FHLB advances were $913.4 million at June 30, 2016, compared to $581.0 million at September 30, 2015. The weighted average contractual rate paid on our FHLB advances was 0.61% at June 30, 2016, and September 30, 2015. The average tenor of our FHLB advances was 40 months and 60 months at June 30, 2016 and September 30, 2015, respectively.

We must collateralize FHLB advances by pledging real estate loans or investments. We pledge more assets than required by our current level of borrowings in order to maintain additional borrowing capacity. Although we may substitute other loans for such pledged loans, we are restricted in our ability to sell or otherwise pledge these loans without substituting collateral or prepaying a portion of the FHLB advances. At June 30, 2016, we had pledged $2.74 billion of loans to the FHLB, against which we had borrowed $913.4 million.

Subordinated Debentures and Subordinated Notes Payable. Interest expense on our outstanding subordinated debentures and subordinated notes payable was $1.0 million in third quarter of fiscal year 2016 and $0.3 million in the comparable quarter in fiscal year 2015. Interest expense for the first nine months of fiscal year 2016 was $2.7 million and was $1.0 million for the comparable period in 2015. At June 30, 2016, the weighted average contractual rate on outstanding subordinated notes was 4.88% compared to 2.39% at September 30, 2015. The increase in interest expense and weighted average contractual rate was due to the payoff of the NAB subordinated debentures which had a lower interest rate than the new private placement subordinated debentures issued in the fourth quarter of fiscal year 2015.

Securities Sold Under Agreements to Repurchase. Securities sold under agreements to repurchase represent retail repurchase agreements with customers and represent a small portion of our overall funding profile. The interest expense associated with this class of liabilities remained largely consistent between the current quarter and comparable quarter.

Rate and Volume Variances

Net interest income is affected by changes in both volume and interest rates. Volume changes are caused by increases or decreases during the year in the level of average interest-earning assets and average interest-bearing liabilities. Rate changes result from increases or decreases in the yields earned on assets or the rates paid on liabilities.

The following table presents the current and comparable quarter and nine month periods and a summary of the changes in interest income and interest expense on a tax equivalent basis resulting from changes in the volume of average asset and liability balances and changes in the average yields or rates compared with the preceding fiscal year. If significant, the change in interest income or interest expense due to both volume and rate has been prorated between the volume and the rate variances based on the dollar amount of each variance. The table illustrates the continued benefit of balance sheet growth, mainly within loans funded by cost-effective deposit growth, partially offset by a reduction in net interest margin most pronounced in loan yield.

Provision for Loan and Lease Losses

We recognized provision for loan and lease losses of $5.4 million for the third quarter of fiscal year 2016 compared to a provision for loan and lease losses of $4.4 million for the comparable period in fiscal year 2015, an increase of $1.0 million between the periods. During the third quarter of fiscal year 2016, the specific reserve portion of the ALLL increased due to credit deterioration in a small number of relationships requiring additional provision for loan and lease losses. Provision for loan and lease losses was $11.9 million for the first nine months of fiscal year 2016 compared to $17.4 million for the comparable period in 2015. The decrease in provision for loan and lease losses compared to the first nine months of fiscal year 2015 was due to a small number of primarily C&I exposures that were charged off in the second quarter of 2015. All ASC 310-30 loans for which we recognized improvements or impairments in the periods presented are covered by FDIC loss-sharing arrangements. We did not record any meaningful provision for loans covered by FDIC loss-sharing arrangements related to non ASC 310-30 loans in any of the periods presented.

* As presented above, the non ASC 310-30 loan portfolio includes originated loans, other than loans for which we have elected the fair value option, and loans we acquired that we did not determine were acquired with deteriorated credit quality.

Total Credit-Related Charges

We recognized other credit-related charges during the quarter that were higher compared to the same quarter in fiscal year 2015 as a result of increased provision driven by higher charge-offs and specific reserves taken on fair value option loans relating to a small number of lending relationships which have been closely monitored and managed for a number of quarters, and had already been classified as "Substandard" loans. We believe that the following table, which summarizes each component of the total credit-related charges incurred during the current and comparable quarter, is helpful to understanding the overall impact on our quarterly results of operations. Net OREO charges include OREO operating costs, valuation adjustments and (loss) gain on sale of OREO properties, each of which entered OREO as a result of the former borrower failing to perform on a loan obligation. Reversal of interest income on nonaccrual loans occurs when we become aware that a loan, for which we had been recognizing interest income, will no longer be able to perform according to the terms and conditions of the loan agreement, including repayment of interest owed to us, while a recovery of interest income on nonaccrual loans occurs when we receive repayment of interest owed to us. Loan fair value adjustments related to credit relate to the portion of our loan portfolio for which we have elected the fair value option; these amounts reflect expected credit losses in the portfolio.

Our noninterest income is comprised of the various fees we charge our customers for products and services we provide and the impact of changes in fair value of loans for which we have elected the fair value treatment and realized and unrealized gains (losses) on the related interest rate swaps we utilize to manage interest rate risk on these loans. While we are required under U.S. GAAP to present both components within total noninterest income, we believe it is helpful to analyze the two broader components of noninterest income separately to better understand the underlying performance of the business.

Noninterest income was $9.1 million for the third quarter of fiscal year 2016, compared to $10.0 million for the comparable period in fiscal year 2015, a decrease of $0.9 million, or 9.1%. This decrease was mostly driven by a net $2.3 million decrease in adjustments to the fair value of our loans held at fair value and related derivatives and partially offset by a $1.4 million increase in product and service fees compared to the same period in fiscal year 2015. Noninterest income for the first nine months of fiscal year 2016 was $26.7 million, an increase of $1.9 million, or 7.6%, compared to the same period in fiscal year 2015. This increase was mostly driven by a net increase of $1.3 million in adjustments to the fair value of our loans held at fair value and related derivatives and an increase of $0.6 million in product and service fees compared to the same period in fiscal year 2015.

Product and Service Fees. We recognized $16.8 million of noninterest income related to product and service fees in the third quarter of fiscal year 2016, an increase of $1.4 million, or 8.9%, compared to the same period in fiscal year 2015. The increase was mainly due to a $2.7 million increase in service charges and other fees, partially offset by a $0.2 million decrease in wealth management fees, a $0.2 million decrease in net gain on sale of loans and a $1.1 million decrease in other income. Shortly after the end of calendar year 2015, we received regulatory approval to revert to higher interchange rates as a result of maintaining consolidated total assets under $10.0 billion as of December 31, 2015. We had previously been subject to capped interchange rates as a result of consolidating our total assets with other U.S. assets held by our former foreign parent company. We estimate that the impact of this change was approximately $2.4 million in the current quarter with the higher rates effective through June 30, 2017.

Noninterest income related to product and service fees was $44.9 million for the first nine months of fiscal year 2016 compared to $44.3 million for the same period in fiscal year 2015, an increase of $0.6 million, or 1.3%. The increase was spread across the major categories of non-interest income, consisting of a $4.2 million increase in service charges and other fees offset by a decrease in wealth management fees of $0.7 million, a decrease of $0.9 million in net gain on sale of loans, and a $1.8 million decrease in other income. Management estimates that the impact of the change in interchange rates was approximately $3.6 million in the first nine months of fiscal year 2016.

Loans at fair value and related derivatives. As discussed in "—Analysis of Financial Condition—Derivatives," changes in the fair value of loans for which we have elected the fair value treatment and realized and unrealized gains and losses on the related derivatives are recognized within noninterest income. For the third quarter of fiscal year 2016, these items accounted for $(7.7) million of noninterest income compared to $(5.4) million for the same period in fiscal year 2015. The change was driven by a net $2.3 million decline in adjustments to the fair value of our loans held at fair value related to $2.7 million of credit deterioration partially offset by an increase in fair value attributable to interest rates. For the first nine months of fiscal year 2016, these items accounted for $(18.1) million of noninterest income compared to $(19.4) million for the same period in fiscal year 2015. The change was driven by a net $1.3 millionincrease in adjustments to the fair value of our loans held at fair value related to credit improvement. We believe that the current realized loss on the derivatives economically offsets the interest income earned on the related loans; we present elsewhere the adjusted net interest income and adjusted net interest margin reflecting the metrics we use to manage the business.

Total noninterest expense	$	150,297	$	141,959

Our noninterest expense consists primarily of salaries and employee benefits, data processing, occupancy expenses, professional fees, communication expenses, advertising and acquisition costs. Noninterest expense was $61.2 million in the third quarter of fiscal year 2016 compared to $46.4 million for the same period in fiscal year 2015, an increase of 31.9% or $14.8 million. The increase in noninterest expense was primarily driven by the acquisition costs of $12.2 million associated with the HF Financial acquisition, and an increase in salaries and employee benefits of $1.7 million due in part to employees added as a part of the HF Financial acquisition.

Noninterest expense was $150.3 million in the first nine months of fiscal year 2016 compared to $142.0 million for the same period in fiscal year 2015, an increase of 5.9% or $8.3 million. The increase in noninterest expense was primarily driven by the acquisition costs of $12.9 million associated with the HF Financial acquisition, along with a $1.6 million increase in data processing resulting from various technology investments, and a $1.9 million increase in other expense, driven by a gain recognized on a fixed asset sale in the comparable period that did not repeat in the current period. This was partially offset by decreases in amortization of intangible assets of $4.2 million and a decrease in the net loss recognized on repossessed property and other related expenses of $5.1 million, due to the reduction in repossessed property balances held compared to the same period in fiscal year 2015.

Our efficiency ratio was 58.8% and 46.4%, respectively, for the three month periods ending June 30,2016 and 2015. The increase was driven by one-time acquisition expenses of $12.2 million related to the HF Financial acquisition. Our efficiency ratio was 50.0% and 48.8%, respectively, for the nine month periods ending June 30,2016 and 2015, with the 2016 ratio elevated due to $12.9 million of HF Financial acquisition related expenses. For more information on our tangible noninterest expense and efficiency ratio, including a reconciliation of each to the most directly comparable GAAP financial measures, see "—Non-GAAP Financial Measures" section.

Provision for Income Taxes

The provision for income taxes varies due to the amount of taxable income, the level and effectiveness of tax-advantaged assets and tax credit funds and the rates charged by federal and state authorities. The provision for income taxes of $7.8 million for the third quarter of fiscal year 2016 represents an effective tax rate of 22.8%, compared to a provision of $14.9 million or an effective tax rate of 34.0% for the comparable period. Included within tax expense for the current quarter is a non-recurring benefit of $3.7 million relating to a correction of an immaterial error of a deferred tax item from an acquisition in 2008. This item is expected to have an immaterial impact on net income for the full 2016 fiscal year. The provision for income taxes of $41.0 million for the first nine months of fiscal year 2016 represents an effective tax rate of 31.9%, compared to a provision of $38.3 million or an effective tax rate of 33.7% for the comparable period.

Our total assets were $11.45 billion at June 30, 2016, compared with $9.80 billion at September 30, 2015. The increase in total assets during the first nine months of fiscal year 2016 was principally attributable to the acquisition of HF Financial, which added assets with an acquired value $1.12 billion, and organic loan growth, which was $418.1 million, or 5.7%, increase from September 30, 2015. At June 30, 2016, loans as shown above were $8.61 billion, compared to $7.33 billion at September 30, 2015, which included loans acquired at a fair value of $863.7 million in the HF Financial acquisition. This growth was primarily driven by growth in CRE loans. During the first nine months of fiscal year 2016, total deposits grew by $230.0 million, or 3.1%, excluding deposits of $863.1 million acquired in the HF Financial acquisition. The net organic growth occurred in both interest bearing and non-interest bearing deposits.

Commercial Non-Real Estate. Commercial non-real estate, or business lending, represents one of our core competencies. We believe that providing a tailored range of integrated products and services, including lending, to small- and medium-enterprise customers is the business at which we excel and through which we can generate favorable returns for our stockholders. We offer a number of different products including working capital and other shorter-term lines of credit, fixed-rate loans over a wide range of terms including our tailored business loans, for which we enter into matching interest rate swaps that give us floating payments for all deals over five years, and variable-rate loans with varying terms. Management has assessed the commercial loan portfolio and our bank's direct exposure to energy-related borrowers is less than 1.2% of total loans, which includes an insignificant oil and gas exposure in North Dakota which was acquired with the HF Financial merger.

Agriculture. Agriculture loans include farm operating loans and loans collateralized by farm land. According to the Federal Deposit Insurance Corporation, at March 31, 2016, we were ranked the eighth-largest farm lender bank in the United States measured by total dollar volume of farm loans, and we take great pride in our knowledge of the agricultural industry across our footprint. We consider agriculture lending one of our core competencies. In 2011, agriculture loans comprised approximately 21% of our overall loan portfolio, compared to 24.3% as of June 30, 2016. We target a 20% to 30% portfolio composition for agriculture loans according to our risk appetite statement approved by our board of directors. Within our agriculture portfolio, loans are diversified across a wide range of subsectors with the majority of the portfolio concentrated within various types of grain, livestock and dairy products, and across different geographical segments within our footprint. While our borrowers have experienced volatile commodity prices during the past several years, we believe there continues to be strong secondary sources of repayment and low borrower leverage for the agriculture loan portfolio.

Commercial Real Estate. CRE includes owner-occupied CRE, non-owner-occupied CRE, construction and development lending, and multi-family residential real estate. While CRE lending will remain a significant component of our overall loan portfolio, we are committed to managing our exposure to riskier construction and development deals specifically, and to CRE lending in general, by targeting relationships with relatively low loan-to-value positions, priced to reflect the amount of risk we accept as the lender.

Residential Real Estate. Residential real estate lending reflects 1-to-4-family real estate construction loans, closed-end first-lien mortgages (primarily single-family long-term first mortgages resulting from acquisitions of other banks), closed-end junior-lien mortgages and home equity lines of credit, or HELOCs. Our closed-end first-lien mortgages include a small percentage of single-family first mortgages that we originate and do not subsequently sell into the secondary market, including jumbo products, adjustable-

- 77-

rate mortgages and rural home mortgages. Conversely, a large percentage of our total single-family first mortgage originations are sold into the secondary market in order to meet our interest rate risk management objectives.

Consumer. Our consumer lending offering comprises a relatively small portion of our total loan portfolio, and predominantly reflects small-balance secured and unsecured products marketed by our retail branches.

Other Lending. Other lending includes all other loan relationships that do not fit within the categories above, primarily consumer and commercial credit cards, customer deposit account overdrafts, and lease receivables.

The following table presents the maturity distribution of our loan portfolio as of June 30, 2016. The maturity dates were determined based on the contractual maturity date of the loan:

OREO

In the normal course of business, we obtain title to parcels of real estate and other assets when borrowers are unable to meet their contractual obligations and we initiate foreclosure proceedings, or via deed in lieu of foreclosure actions. OREO assets are considered nonperforming assets. When we obtain title to an asset, we evaluate how best to maintain and protect our interest in the property and seek to liquidate the asset at an acceptable price in a timely manner. Our total OREO carrying value was $11.7 million as of June 30, 2016, a decrease of $0.5 million, or 4.1% and a decrease of $4.2 million, or 26.4%, compared to March 31, 2016 and September 30, 2015, respectively. The amount of OREO covered by FDIC loss-sharing arrangements was $0.1 million as of June 30, 2016 and September 30, 2015. The following tables present our OREO balances for the period indicated:

We have historically invested excess deposits in high-quality, liquid investment securities including residential agency mortgage-backed securities and, to a lesser extent, U.S. Treasury securities, corporate debt securities and securities issued by U.S. states and political subdivisions. Our investment portfolio serves as a means to collateralize FHLB borrowings and public funds deposits, to earn net spread income on excess deposits and to maintain liquidity and balance interest rate risk. U.S. Treasury securities comprised 17.0% of the total market value of the portfolio as of June 30, 2016. Since September 30, 2015, the fair value of the

portfolio has increased by $33.8 million, or 2.5%. The HF Financial acquisition had a minimal impact on the investment portfolio size and composition.

The following tables present the aggregate amortized cost of each investment category of the investment portfolio and the weighted average yield for each investment category for each maturity period at June 30, 2016. Maturities of mortgage-backed securities may differ from contractual maturities because the mortgages underlying the securities may be called or prepaid without any penalties. The weighted-average yield on these assets is presented below based on the contractual rate, as opposed to a tax equivalent yield concept.

Asset Quality

We place an asset on nonaccrual status when any installment of principal or interest is more than 90 days past due (except for loans that are well secured and in the process of collection) or earlier when management determines the ultimate collection of all contractually due principal or interest to be unlikely. Restructured loans for which we grant payment or significant interest rate concessions are placed on nonaccrual status until collectability improves and a satisfactory payment history is established, generally by the receipt of at least six consecutive payments. Our collection policies related to delinquent and charged-off loans are highly focused on individual relationships, and we believe that these policies are in compliance with all applicable laws and regulations.

The following table presents the dollar amount of nonaccrual loans, OREO, restructured performing loans and accruing loans over 90 days past due, at the end of the dates indicated. Loans covered by FDIC loss-sharing arrangements are generally pooled with other similar loans and are accreting purchase discount into income each period. Subject to compliance with the applicable loss-sharing agreement, we are indemnified by the FDIC at a rate of 80% for any future credit losses on loans covered by a FDIC loss-sharing arrangement through June 4, 2020 for single-family real estate loans.

At June 30, 2016, our nonperforming assets were 1.23% of total assets, compared to 0.86% at September 30, 2015. Nonaccrual loans were $108.2 million as of June 30, 2016, with $4.2 million of the balance covered by FDIC loss-sharing arrangements. Total nonaccrual loans increased by $53.2 million during the quarter and increased by $39.9 million compared to September 30, 2015. The increase in nonaccrual loans was primarily driven by the deterioration of a small number of lending relationships, which have been closely monitored and managed for a number of quarters, and had already been classified as "Substandard" loans. Total OREO balances were $11.7 million as of June 30, 2016, a decrease of $0.5 million, or 4.1%, compared to prior quarter and a decrease of $4.2 million, or 26.4%, compared to September 30, 2015.

Excluding loans covered by FDIC loss-sharing arrangements, we had average nonaccrual loans (calculated as a two-point average) of $83.5 million outstanding during the first nine months of fiscal year 2016. Based on the average loan portfolio yield for these loans for the the first nine months of fiscal year 2016, we estimate that interest income would have been $2.0 million higher during this period had these loans been accruing. During the same period, the amount of net interest income that we recorded on these loans was immaterial.

Nonaccrual loans covered by FDIC loss-sharing arrangements continued to decline and are down $1.1 million since September 30, 2015, due to natural runoff through payment.

We consistently monitor all loans internally rated “watch” or worse because that rating indicates we have identified some potential weakness emerging; but loans rated “watch” will not necessarily become problem loans or become impaired. Aside from the loans on the watch list, we do not believe we have any potential problem loans that are not already identified as nonaccrual, past due or restructured as it is our policy to promptly reclassify loans as soon as we become aware of doubts as to the borrowers’ ability to meet repayment terms. We do not have any material interest-bearing assets that would be disclosed as nonperforming loans or restructured performing loans if they were loans.

When we grant concessions to borrowers that we would not otherwise grant if not for the borrowers’ financial difficulties, such as reduced interest rates or extensions of loan periods, we consider these modifications troubled debt restructurings ("TDRs").

We entered into loss-sharing arrangements with the FDIC related to certain assets (loans and OREO) acquired from TierOne Bank on June 4, 2010.

Allowance for Loan and Lease Losses

We establish an allowance for the inherent risk of probable losses within our loan portfolio. The allowance for loan and lease losses is management’s best estimate of probable credit losses that are incurred in the loan portfolio. We determine the allowance for loan and lease losses based on an ongoing evaluation, driven primarily by monitoring changes in loan risk grades, delinquencies and other credit risk indicators, which is an inherently subjective process. We consider the uncertainty related to certain industry sectors and the extent of credit exposure to specific borrowers within the portfolio. In addition, we consider concentration risks associated with the various loan portfolios and current economic conditions that might impact the portfolio. All of these estimates are susceptible to significant change. Changes to the allowance for loan and lease losses are made by charges to the provision for loan and lease losses. Loans deemed to be uncollectible are charged off against the allowance for loan and lease losses. Recoveries of amounts previously charged-off are credited to the allowance for loan and lease losses.

Our allowance for loan and lease losses consists of two components. For non-impaired loans, we calculate a weighted average ratio of 12-, 36- and 60-month historical realized losses by collateral type; adjust as necessary for our interpretation of current economic conditions and current portfolio trends including credit quality, concentrations, aging of the portfolio and/or significant policy and underwriting changes not entirely covered by the calculated historical loss rates; and apply the loss rates to outstanding loan balances in each collateral category. We calculate the weighted average ratio of 12-, 36- and 60-month historical realized losses for each collateral type by dividing the average net annual charge-offs by the average outstanding loans of such type subject to the calculation for each of the 12-, 36- and 60-month periods, then averaging those three results. For impaired loans, we estimate our exposure for each individual relationship, given the current payment status of the loan, the present value of expected payments and the value of the underlying collateral as supported by third party appraisals, broker’s price opinions, and/or the borrower’s audited financial statements, each adjusted for liquidation costs. Any shortfall between the liquidation value of the underlying collateral and the recorded investment value of the loan is considered the required specific reserve amount. Actual losses in any period may exceed allowance amounts. We evaluate and adjust our allowance for loan and lease losses, and the allocation of the allowance between loan categories, each month.

In the first nine months of fiscal year 2016, net charge-offs were $4.8 million, or 0.08% of average total loans, comprised of $8.1 million of charge-offs and $3.3 million of recoveries. For fiscal year 2015, net charge-offs were $9.4 million, or 0.13%, of average total loans.

At June 30, 2016, the allowance for loan and lease losses was 0.75% of our total loan portfolio, a 3 basis point decrease compared to 0.78% at September 30, 2015. The decrease was driven by the addition of loans acquired during the quarter with no carryover of the related ALLL. The balance of the ALLL increased from $57.2 million to $64.2 million over the same period.

- 85-

Additionally, a portion of our loans which are carried at fair value, totaling $1.16 billion at June 30, 2016 and $1.12 billion at September 30, 2015, respectively, have no associated allowance for loan and lease losses, but rather have a fair value adjustment related to credit risk included within their carrying value, thus driving the overall ratio of allowance for loan and lease losses to total loans lower. The amount of fair value adjustment related to credit risk on these loans was $8.1 million and $5.7 million at June 30, 2016 and September 30, 2015, respectively.

The following tables present management’s historical allocation of the allowance for loan and lease losses by loan category, in both dollars and percentage of our total allowance for loan and lease losses, to specific loans in those categories at the dates indicated:

Management will continue to evaluate the loan portfolio and assess economic conditions in order to determine future allowance levels and the amount of loan and lease loss provisions. We review the appropriateness of our allowance for loan and lease losses on a monthly basis. Management monitors closely all past due and restructured loans in assessing the appropriateness of its allowance for loan and lease losses. In addition, we follow procedures for reviewing and grading all substantial commercial and agriculture relationships at least annually. Based predominantly upon the review and grading process, we determine the appropriate level of the allowance in response to our assessment of the probable risk of loss inherent in our loan portfolio. Management will make additional loan and lease loss provisions when the results of its problem loan assessment methodology or overall allowance appropriateness test indicate additional provisions are required.

The review of problem loans is an ongoing process during which management may determine that additional charge-offs are required or additional loans should be placed on nonaccrual status. We recorded provision for loan and lease losses of $5.4 million during the third quarter of fiscal year 2016. We have also recorded an allowance for unfunded lending-related commitments that represents our estimate of incurred losses on the portion of lending commitments that borrowers have not advanced. The balance of the allowance for unfunded lending-related commitments was $0.5 million and $0.4 million at June 30, 2016 and September 30, 2015, respectively.

Deposits

We obtain funds from depositors by offering consumer and business demand deposit accounts, MMDAs, NOW accounts, savings accounts and term CDs. At June 30, 2016 and September 30, 2015, our total deposits were $8.48 billion and $7.39 billion, respectively, an increase of 14.8% including $863.1 million of fair value deposits acquired in the HF Financial acquisition. Net growth excluding acquired deposits was $230.0 million, or 3.1%, which was spread across primarily commercial and public deposit accounts. Our accounts are federally insured by the FDIC up to the legal maximum. We have significantly shifted the composition of our deposit portfolio away from CDs toward demand, NOW, MMDA and savings accounts over the last 48 months. This has dramatically reduced our overall cost of deposit funding, in addition to the fact that we have greatly increased adherence to internally published rate offerings for various types of deposit account offerings. The following table presents the balances and weighted average cost of our deposit portfolio at the following dates:

We fund a portion of our assets with CDs that have balances of $250,000 or more and that have maturities generally in excess of six months. At June 30, 2016 and September 30, 2015, our CDs of $250,000 or more totaled $258.1 million and $217.0 million, respectively. The following table presents the maturities of our CDs of $250,000 or more and less than $250,000 in size at June 30, 2016:

Derivatives

In the normal course of business, we enter into fixed-rate loans having original maturities of 5 years or greater (typically between 5 and 15 years) with certain of our commercial and agribusiness banking customers to assist them in facilitating their risk management strategies. We mitigate our interest rate risk associated with certain of these loans by entering into equal and offsetting fixed-to-floating interest rate swap agreements for these loans with swap counterparties. We have elected to account for the loans at fair value under ASC 825 Fair ValueOption. Changes in the fair value of these loans are recorded in earnings as a component of noninterest income in the relevant period. The related interest rate swaps are recognized as either assets or liabilities in our financial statements and any gains or losses on these swaps, both realized and unrealized, are recorded in earnings as a component of noninterest income. The economic hedges are fully effective from an interest rate risk perspective, as gains and losses on our swaps are directly offset by changes in fair value of the hedged loans (i.e., swap interest rate risk adjustments are directly offset by associated loan interest rate risk adjustments). Consequently, any changes in noninterest income associated with changes in fair value resulting from interest rate movement, as opposed to changes in credit quality, on the loans are directly offset by equal and opposite unrealized charges to or reductions in noninterest income for the related interest rate swap. Any changes in the fair value of the loans related to credit quality and the current realized gain (loss) on derivatives are not offsetting amounts within noninterest income. To ensure the correlation of movements in fair value between the interest rate swap and the related loan, we pass on all economic costs associated with our hedging activity resulting from loan customer prepayments (partial or full) to the customer.

On July 31, 2015, we agreed to a $10.0 million revolving line of credit with Wells Fargo Bank, which expires July 28, 2017,at an interest rate of LIBOR + 200 basis points. At June 30, 2016, we did not have any advances on the line of credit.

Other Borrowings

We have outstanding $80.9 million and $56.1 million, respectively, of junior subordinated debentures to affiliated trusts in connection with the issuance of trust preferred securities by such trusts as of June 30, 2016 and September 30, 2015. We are permitted under applicable laws and regulations to count these trust preferred securities as part of our Tier 1 capital.

On July 31, 2015, we issued $35.0 million of fixed-to-floating rate subordinated notes that mature on August 15, 2025 through a private placement. The notes, which qualify as Tier 2 capital under capital rules in effect at June 30, 2016, have an interest rate of 4.875% per annum, payable semi-annually on each February15 and August 15, commencing on February 15, 2016 until August 15, 2020. During the first nine months of fiscal year 2016, we incurred $2.7 million in interest expense compared to $1.0 million in the comparable period of fiscal year 2015, which related to different lower-priced notes with the same par value and the increase in subordinated debt acquired in the HF Financial acquisition.

Instruments with Off-Balance Sheet Risk

In the normal course of business, we enter into various transactions that are not included in our consolidated financial statements in accordance with GAAP. These transactions include commitments to extend credit to our customers and letters of credit. Commitments to extend credit are agreements to lend to a customer provided there is no violation of any condition established in the commitment. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Letters of credit are conditional commitments issued primarily to support or guarantee the performance of a customer’s obligations to a third party. The credit risk involved in issuing letters of credit is essentially the same as originating a loan to the customer. We manage the risks associated with these arrangements by evaluating each customer’s creditworthiness prior to issuance through a process similar to that used by us in deciding whether to extend credit to the customer.

The following table presents the total notional amounts of all commitments by us to extend credit and letters of credit as of the dates indicated:

	June 30, 2016		September 30, 2015

Liquidity

Liquidity refers to our ability to maintain cash flow that is adequate to fund operations and meet present and future financial obligations through either the sale or maturity of existing assets or by obtaining additional funding through liability management. We consider the effective and prudent management of liquidity to be fundamental to our health and strength. Our objective is to manage our cash flow and liquidity reserves so that they are adequate to fund our obligations and other commitments on a timely basis and at a reasonable cost.

Our liquidity risk is managed through a comprehensive framework of policies and limits overseen by our bank’s asset and liability committee. We continuously monitor and make adjustments to our liquidity position by adjusting the balance between sources and uses of funds as we deem appropriate. Our primary measures of liquidity include monthly cash flow analyses under ordinary business activities and conditions and under situations simulating a severe run on our bank. We also monitor our bank’s deposit to loan ratio to ensure high quality funding is available to support our strategic lending growth objectives, and have internal management targets for the FDIC’s liquidity ratio, net short-term non-core funding dependence ratio and non-core liabilities to total assets ratio. The results of these measures and analyses are incorporated into our contingency funding plan, which provides the basis for the identification of our liquidity needs.

Great Western Bancorp, Inc. Great Western Bancorp, Inc.'s ("GWBI") primary source of liquidity is cash obtained from dividends paid by our bank. We primarily use our cash for the payment of dividends, when and if declared by our board of directors, and the payment of interest on our outstanding junior subordinated debentures and subordinated notes. We also use cash, as necessary, to satisfy the needs of our bank through equity contributions and for acquisitions. At June 30, 2016, GWBI had $7.5 million of cash, compared to $37.3 million at the end of the previous quarter with the decrease primarily due to the acquisition of HF Financial. During the third quarter of fiscal year 2016, we declared and paid a dividend of $0.14 per share. The outstanding amounts under our revolving line of credit with Wells Fargo and our private placement subordinated capital notes together totaled $35.0 million at June 30, 2016. Our management believes that the sources of available liquidity are adequate to meet all reasonably foreseeable short-term and intermediate-term demands. We may consider raising additional capital in public or private offerings of debt or equity securities.

Great Western Bank. Our bank maintains sufficient liquidity by maintaining minimum levels of excess cash reserves (measured on a daily basis), a sufficient amount of unencumbered, highly liquid assets and access to contingent funding with the FHLB. At June 30, 2016, our bank had cash of $475.8 million and $1.36 billion of highly-liquid securities held in our investment portfolio, of which $957.0 million were pledged as collateral on public deposits, securities sold under agreements to repurchase, and for other purposes as required or permitted by law. The balance could be sold to meet liquidity requirements. Our bank also had $913.4 million in FHLB borrowings at June 30, 2016, with additional available lines of $684.7 million. Our bank primarily uses liquidity to meet loan requests and commitments (including commitments under letters of credit), to accommodate outflows in deposits and to take advantage of interest rate market opportunities. At June 30, 2016, we had a total of $2.21 billion of outstanding exposure under commitments to extend credit and issued letters of credit. Our management believes that the sources of available liquidity are adequate to meet all our bank’s reasonably foreseeable short-term and intermediate-term demands.

Capital

As a bank holding company, we must comply with the capital requirements established by the Federal Reserve, and our bank must comply with the capital requirements established by the FDIC. The current risk-based guidelines applicable to us and our bank are based on the Basel III framework, as implemented by the federal bank regulators.

Risk-weighted assets	8,991,609

At June 30, 2016 and September 30, 2015, our Tier 1 capital included an aggregate of $77.1 million and $56.1 million, respectively, of trust preferred securities issued by our subsidiaries. At June 30, 2016, our Tier 2 capital included $64.2 million of the allowance for loan and lease losses and $35.0 million of private placement subordinated capital notes. At September 30, 2015, our Tier 2 capital included $57.2 million of the allowance for loan and lease losses and $35.0 million of private placement subordinated capital notes. Our total risk-weighted assets were $8.99 billion at June 30, 2016.

Non-GAAP Financial Measures

We rely on certain non-GAAP measures in making financial and operational decisions about our business which adjusts for certain items that we do not consider reflective of our business performance. We believe that each of the non-GAAP measures presented is helpful in highlighting trends in our business, financial condition and results of operations which might not otherwise be apparent when relying solely on our financial results calculated in accordance with U.S. generally accepted accounting principles, or GAAP.

In particular, we evaluate our profitability and performance based on our adjusted net income, adjusted earnings per share, cash net income and return on average tangible common equity. Our adjusted net income and adjusted earnings per share exclude the after-tax effect of items with a significant impact to net income that we do not believe to be recurring in nature, e.g., one-time acquisition expenses. Our cash net income and return on tangible common equity exclude the effects of amortization expense relating to intangible assets and related tax effects from the acquisition of us by NAB and our acquisitions of other institutions. We believe these measures help highlight trends associated with our financial condition and results of operations by providing net income and return information excluding significant nonrecurring items (for adjusted net income and adjusted earnings per share) and based on our cash payments and receipts during the period (for cash net income and return on average tangible common equity).

We also evaluate our profitability and performance based on our adjusted net interest income, adjusted net interest margin, adjusted interest income on non ASC 310-30 loans and adjusted yield on non ASC 310-30 loans. We adjust each of these four measures to include the current realized gain (loss) of derivatives we use to manage interest rate risk on certain of our loans, which we believe economically offsets the interest income earned on the loans. Similarly, we evaluate our operational efficiency based on our efficiency ratio, which excludes the effect of amortization of core deposit and other intangibles (a non-cash expense item) and includes the tax benefit associated with our tax-advantaged loans.

- 92-

We evaluate our financial condition based on the ratio of our tangible common equity to our tangible assets and the ratio of our tangible common equity to common shares outstanding. Our calculations of these ratios exclude the effect of goodwill and other intangible assets. We believe this measure is helpful in highlighting the common equity component of our capital and because of its focus by federal bank regulators when reviewing the health and strength of financial institutions in recent years and when considering regulatory approvals for certain actions, including capital actions. We also believe the ratio of our tangible common equity to common shares outstanding is helpful in understanding our stockholders’ relative ownership position as we undertake various actions to issue and retire common shares outstanding.

Reconciliations for each of these non-GAAP financial measures to the closest GAAP financial measures are included in the tables below. Each of the non-GAAP measures presented should be considered in context with our GAAP financial results included in this filing.

Impact of Inflation and Changing Prices

Our financial statements included in this report have been prepared in accordance with GAAP, which requires us to measure financial position and operating results primarily in terms of historic dollars. Changes in the relative value of money due to inflation or recession generally are not considered. The primary effect of inflation on our operations is reflected in increased operating costs. In our management’s opinion, changes in interest rates affect the financial condition of a financial institution to a far greater degree than changes in the inflation rate. While interest rates are greatly influenced by changes in the inflation rate, they do not necessarily change at the same rate or in the same magnitude as the inflation rate. Interest rates are highly sensitive to many factors that are beyond our control, including changes in the expected rate of inflation, the influence of general and local economic conditions and the monetary and fiscal policies of the United States government, its agencies and various other governmental regulatory authorities.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of June 30, 2016, there have been no material changes in the quantitative and qualitative information about market risk provided pursuant to Item 305 of Regulation S-K as presented in our Annual Report on Form 10-K for the fiscal year ended September 30, 2015.

Evaluation of Interest Rate Risk

We use a net interest income simulation model to measure and evaluate potential changes in our net interest income. We run various hypothetical interest rate scenarios at least monthly and compare these results against a scenario with no changes in interest rates. Our net interest income simulation model incorporates various assumptions, which we believe are reasonable but which may have a significant impact on results such as: (1) the timing of changes in interest rates, (2) shifts or rotations in the yield curve, (3) re-pricing characteristics for market-rate-sensitive instruments on and off balance sheet, (4) differing sensitivities of financial instruments due to differing underlying rate indices, (5) varying loan prepayment speeds for different interest rate scenarios, (6) the effect of interest rate limitations in our assets, such as floors and caps, (7) the effect of our interest rate swaps, and (8) overall growth and repayment rates and product mix of assets and liabilities. Because of limitations inherent in any approach used to measure interest rate risk, simulation results are not intended as a forecast of the actual effect of a change in market interest rates on our results but rather as a means to better plan and execute appropriate asset-liability management strategies and manage our interest rate risk.

Potential changes to our adjusted net interest income (i.e., GAAP net interest income plus current realized gain or loss on derivatives) in hypothetical rising and declining rate scenarios calculated as of June 30, 2016 are presented in the following table. The projections assume (1) immediate, parallel shifts downward of the yield curve of 100 basis points and immediate, parallel shifts upward of the yield curve of 100, 200, 300 and 400 basis points and (2) gradual shifts downward of 100 basis points over 12 months and gradual shifts upward of 100, 200, 300 and 400 basis points over 12 months. In the current interest rate environment, a downward shift of the yield curve of 200, 300 and 400 basis points does not provide us with meaningful results. In a downward parallel shift of the yield curve, interest rates at the short-end of the yield curve are not modeled to decline any further than 0%. For the immediate-shift scenarios, we assume short-term rates follow a forward yield curve throughout the forecast period that is dictated by the instantaneously shocked yield curve from the as of date. In the gradual-shift scenarios, we take each rate across the yield curve from the as of date and shock it by 1/12th of the total change in rates each month for twelve months.

	Estimated Increase (Decrease) in Annualized Adjusted Net Interest Income for the Quarter Ended June 30, 2016
Change in Market Interest Rates as of June 30, 2016	Twelve Months Ending June 30, 2017		Twelve Months Ending June 30, 2018
Immediate Shifts
+400 basis points	12.01	%	9.44	%
+300 basis points	9.03	%	7.18	%
+200 basis points	6.02	%	4.84	%
+100 basis points	3.02	%	2.55	%
-100 basis points	(1.17	)%	(1.70	)%
Gradual Shifts
+400 basis points	2.78	%
+300 basis points	2.15	%
+200 basis points	1.53	%
+100 basis points	0.88	%
-100 basis points	(0.22	)%

We primarily use interest rate swaps to ensure that long-term fixed-rate loans are effectively re-priced as short-term rates change, which we believe would allow us to achieve these results.  The results of this simulation analysis are hypothetical, and a variety of factors might cause actual results to differ substantially from what is depicted. For example, if the timing and magnitude of

- 96-

interest rate changes differ from those projected, our net interest income might vary significantly. Non-parallel yield curve shifts such as a flattening or steepening of the yield curve or changes in interest rate spreads, would also cause our net interest income to be different from that depicted. An increasing interest rate environment could reduce projected net interest income if deposits and other short-term liabilities re-price faster than expected or faster than our assets re-price. Actual results could differ from those projected if we grow assets and liabilities faster or slower than estimated, if we experience a net outflow of deposit liabilities or if our mix of assets and liabilities otherwise changes. Actual results could also differ from those projected if we experience substantially different repayment speeds in our loan portfolio than those assumed in the simulation model. Finally, these simulation results do not contemplate all the actions that we may undertake in response to potential or actual changes in interest rates, such as changes to our loan, investment, deposit, funding or hedging strategies.

For more information on our adjusted net interest income, including a reconciliation to the most directly comparable GAAP financial measures, see "—Non-GAAP Financial Measures" above.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures.    As of the end of the period covered by this report, our management carried out an evaluation, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act), to ensure that information required to be disclosed in reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the design and operation of these disclosure controls and procedures were effective as of the end of the period covered by this report.

(b) Changes in Internal Control over Financial Reporting.    During the most recently completed fiscal quarter, there was no change made in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Accounting Policies [Abstract]

Nature of Operations and Summary of Significant Policies

Nature of Operations and Summary of Significant Policies

Nature of Operations

Great Western Bancorp, Inc. (the “Company”) is a bank holding company organized under the laws of Delaware. The primary business of the Company is ownership of its wholly owned subsidiary, Great Western Bank (the “Bank”). The Bank is a full-service regional bank focused on relationship-based business and agribusiness banking in Arizona, Colorado, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota and South Dakota. The Company and the Bank are subject to the regulation of certain federal and/or state agencies and undergo periodic examinations by those regulatory authorities. Substantially all of the Company’s income is generated from banking operations.

Basis of Presentation

The accompanying unaudited consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and reflect all adjustments that are, in the opinion of management, necessary for the fair presentation of the financial position and results of operations for the periods presented. All such adjustments are of a normal recurring nature.

Certain previously reported amounts have been reclassified to conform to the current presentation.

The unaudited interim consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended September 30, 2015, which includes a description of significant accounting policies. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year or any other period.

The accompanying unaudited consolidated financial statements include the accounts and results of operations of the Company and its subsidiaries after elimination of all significant intercompany accounts and transactions. The preparation of unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates.

Business Combinations

The Company accounts for business combinations under the acquisition method of accounting in accordance with ASC 805, “Business Combinations” (“ASC 805”). The Company recognizes the fair value of the assets acquired and liabilities assumed, immediately expenses transaction costs and accounts for restructuring plans separately from the business combination. There is no separate recognition of the acquired allowance for loan and lease losses on the acquirer’s balance sheet as credit related factors are incorporated directly into the fair value of the loans recorded at the acquisition date. The excess of the cost of the acquisition over the fair value of the net tangible and intangible assets acquired is recorded as goodwill. Alternatively, a bargain purchase gain is recorded equal to the amount by which the fair value of assets purchased exceeds the fair value of liabilities assumed and consideration paid.

Results of operations of the acquired business are included in the consolidated statements of comprehensive income from the effective date of acquisition.

Securities

The Company classifies securities upon purchase in one of three categories: trading, held to maturity, or available for sale. Debt and equity securities held for resale are classified as trading. Debt securities for which the Company has the ability and positive intent to hold until maturity are classified as held to maturity. All other securities are classified as available for sale as they may be sold prior to maturity in response to changes in the Company’s interest rate risk profile, funding needs, demand for collateralized deposits by public entities or other reasons.

Held to maturity securities are stated at amortized cost, which represents actual cost adjusted for premium amortization and discount accretion. Available for sale securities are stated at fair value, with unrealized gains and losses, net of related taxes, included in stockholders’ equity as a component of accumulated other comprehensive income (loss).

Trading securities are stated at fair value. Realized and unrealized gains and losses from sales and fair value adjustments of trading securities are included in other noninterest income in the consolidated statements of comprehensive income.

Purchases and sales of securities are recognized on a trade date basis. The cost of securities sold is based on the specific identification method.

Declines in the fair value of investment securities available for sale (with certain exceptions for debt securities noted below) that are deemed to be other-than-temporary are recognized in earnings as a realized loss, and a new cost basis for the securities is established. In evaluating other-than-temporary impairment, management considers the length of time and extent to which the fair value has been less than amortized cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value in the near term. Declines in the fair value of debt securities below amortized cost are deemed to be other-than-temporary in circumstances where: (1) the Company has the intent to sell a security; (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security. If the Company intends to sell a security or if it is more likely than not that the Company will be required to sell the security before recovery, an other-than-temporary impairment loss is recognized in earnings equal to the difference between the security’s amortized cost basis and its fair value. If the Company does not intend to sell the security or it is not more likely than not that it will be required to sell the security before recovery, the other-than-temporary impairment write-down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in accumulated other comprehensive income (loss).

Interest and dividends, including amortization of premiums and accretion of discounts, are recognized as interest or dividend income when earned. Realized gains and losses on sales (using the specific identification method) and declines in value judged to be other- than-temporary are included in noninterest income in the consolidated statements of comprehensive income.

Loans

The Company’s accounting method for loans differs depending on whether the loans were originated or purchased and, for purchased loans, whether the loans were acquired at a discount related to evidence of credit deterioration since date of origination.

Originated Loans

Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or pay-off, generally are reported at their outstanding principal balance, adjusted for charge-offs, the allowance for loan and lease losses, and any unamortized deferred fees or costs. Other fees, not associated with originating a loan are recognized as fee income when earned.

Interest income on loans is accrued daily on the outstanding balances. Accrual of interest is discontinued when management believes, after considering collection efforts and other factors, the borrower’s financial condition is such that collection of interest is doubtful, which is generally at 90 days past due. Generally, when loans are placed on nonaccrual status, interest receivable is reversed against interest income in the current period. Interest payments received thereafter are applied as a reduction to the remaining principal balance as long as concern exists as to the ultimate collection of the principal. Loans are removed from nonaccrual status when they become current as to both principal and interest and concern no longer exists as to the collectability of principal and interest.

The Company has elected to measure certain long-term loans and written loan commitments at fair value to assist in managing interest rate risk for longer-term loans. Fair value loans are fixed-rate loans having original maturities of 5 years or greater (typically between 5 and 15 years) to our business and agribusiness banking customers to assist them in facilitating their risk management strategies. The fair value option was elected upon the origination or acquisition of these loans and written loan commitments. Interest income is recognized in the same manner on loans reported at fair value as on non-fair value loans, except in regard to origination fees and costs which are recognized immediately upon closing. The changes in fair value of long-term loans and written loan commitments at fair value are reported in noninterest income.

For loans held for sale, loan fees charged or received on origination, net of certain direct loan origination costs, are recognized in income when the related loan is sold. For loans held for investment, loan fees, net of certain direct loan origination costs, are deferred, and the net amount is amortized as an adjustment of the related loan’s yield. The Company is generally amortizing these amounts over the contractual lives of the loans. Commitment fees are recognized as income when received.

The Company grants commercial, agricultural, consumer, residential real estate, and other loans to customers primarily in Arizona, Colorado, Iowa, Kansas, Missouri, Minnesota, Nebraska, North Dakota and South Dakota. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the borrower. Collateral held varies but includes accounts receivable, inventory, property and equipment, residential real estate, and income-producing commercial and agricultural properties. Government guarantees are also obtained for some loans, which reduces the Company’s risk of loss.

Loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value. Loans held for sale include fixed rate single-family residential mortgage loans under contract to be sold in the secondary market. In most cases, loans are carried at cost and sold within 45 days. These loans are sold with the mortgage servicing rights released. Under limited circumstances, buyers may have recourse to return a purchased loan to the Company. Recourse conditions may include early payment default, breach of representation or warranties, or documentation deficiencies.

Fair value of loans held for sale is determined based on prevailing market prices for loans with similar characteristics, sale contract prices, or, for certain portfolios, discounted cash flow analysis. Declines in fair value below cost (and subsequent recoveries) are recognized in net gain on sale of loans. Deferred fees and costs related to these loans are not amortized but are recognized as part of the cost basis of the loan at the time it is sold. Gains or losses on sales are recognized upon delivery and included in net gain on sale of loans.

Purchased Loans

Loans acquired (non-impaired and impaired) in a business acquisition are recorded at their fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date.

In determining the acquisition date fair value of purchased loans with evidence of credit deterioration (“ASC 310-30 loans”), and in subsequent accounting, the Company generally aggregates impaired purchased consumer and certain smaller balance impaired commercial loans into pools of loans with common risk characteristics, while accounting for larger-balance impaired commercial loans individually. Expected cash flows at the acquisition date in excess of the fair value of loans are recorded as interest income over the life of the loans using a level-yield method.

Management estimates the cash flows expected to be collected at acquisition and at subsequent measurement dates using internal risk models, which incorporate the estimate of key assumptions, such as default rates, loss severity, and prepayment speeds. Subsequent to the acquisition date, decreases in cash flows over those expected at the acquisition date are recognized by recording an allowance for loan and lease losses. Subsequent increases in cash flow over those expected at the acquisition date are recognized as reductions to allowance for loan and lease losses to the extent impairment was previously recognized and thereafter as interest income prospectively.

For purchased loans not deemed impaired at the acquisition date, the difference between the fair value and the unpaid principal balance of the loan at acquisition date is amortized or accreted to interest income using the effective interest method over the remaining period to contractual maturity.

Credit Risk Management

The Company’s strategy for credit risk management includes well-defined, centralized credit policies, uniform underwriting criteria and ongoing risk monitoring and review processes for all credit exposures. The strategy also emphasizes diversification on a geographic, industry, and customer level; regular credit examinations; and management reviews of loans exhibiting deterioration of credit quality. The credit risk management strategy also includes a credit risk assessment process that performs assessments of compliance with commercial and consumer credit policies, risk ratings, and other critical credit information. Loan decisions are documented with respect to the borrower’s business, purpose of the loan, evaluation of the repayment sources, and the associated risks, evaluation of collateral, covenants and monitoring requirements, and risk rating rationale.

The Company categorizes its loan portfolio into six classes, which is the level at which it develops and documents a systematic methodology to determine the allowance for loan and lease losses. The Company’s six loan portfolio classes are residential real estate, commercial real estate, commercial non real estate, agriculture, consumer and other lending.

The residential real estate lending class includes loans made to consumer customers including residential mortgages, residential construction loans and home equity loans and lines. These loans are typically fixed rate loans secured by residential real estate. Home equity lines are revolving accounts giving the borrower the ability to draw and repay balances repeatedly, up to a maximum commitment, and are secured by residential real estate. Home equity lines typically have variable rate terms which are benchmarked to a prime rate. Historical loss history is the primary factor in determining the allowance for loan and lease losses for the residential real estate lending class. Key risk characteristics relevant to residential real estate lending class loans primarily relate to the borrower’s capacity and willingness to repay and include unemployment rates and other economic factors, and customer payment history. These risk characteristics, among others, are reflected in the environmental factors considered in determining the allowance for loan and lease losses.

The commercial real estate lending class includes loans made to small and middle market businesses, including multifamily properties. Loans in this class are secured by commercial real estate. Historical loss history and updated loan-to-value information on collateral-dependent loans are the primary factors in determining the allowance for loan and lease losses for the commercial real estate lending class. Key risk characteristics relevant to the commercial real estate lending class include the industry and geography of the borrower’s business, purpose of the loan, repayment sources, borrower’s debt capacity and financial performance, loan covenants, and nature of pledged collateral. We consider these risk characteristics in assigning risk ratings and estimating environmental factors considered in determining the allowance for loan and lease losses.

The commercial non real estate lending class includes loans made to small and middle market businesses, and loans made to public sector customers. Loans in this class are generally secured by business assets and guaranteed by owners; cashflows are most often our primary source of repayment. Historical loss history and updated loan-to-value information on collateral-dependent loans are the primary factors in determining the allowance for loan and lease losses for the commercial non real estate lending class. Key risk characteristics relevant to the commercial non real estate lending class include the industry and geography of the borrower’s business, purpose of the loan, repayment sources, borrower’s debt capacity and financial performance, loan covenants, and nature of pledged collateral. We consider these risk characteristics in assigning risk ratings and estimating environmental factors considered in determining the allowance for loan and lease losses.

The agriculture lending class includes loans made to small and mid-size agricultural businesses and individuals. Loans in this class are generally secured by operating assets and guaranteed by owners; cashflows are most often our primary source of repayment. Historical loss history and updated loan-to-value information on collateral-dependent loans are the primary factors in determining the allowance for loan and lease losses for the agriculture lending class. Key risk characteristics relevant to the agriculture lending class include the geography of the borrower’s operations, commodity prices and weather patterns, purpose of the loan, repayment sources, borrower’s debt capacity and financial performance, loan covenants, and nature of pledged collateral. We consider these risk characteristics in assigning risk ratings and estimating environmental factors considered in determining the allowance for loan and lease losses.

The consumer lending class includes loans made to consumer customers including loans secured by automobiles and other installment loans, and the other lending class includes credit card loans and unsecured revolving credit lines. Historical loss history is the primary factor in determining the allowance for loan and lease losses for the consumer and other lending classes. Key risk characteristics relevant to loans in the consumer and other lending classes primarily relate to the borrower’s capacity and willingness to repay and include unemployment rates and other economic factors, and customer payment and overall credit history. These risk characteristics, among others, are reflected in the environmental factors considered in determining the allowance for loan and lease losses.

The Company assigns all non-consumer loans a credit quality risk rating. These ratings are Pass, Watch, Substandard, Doubtful, and Loss. Loans with a Pass and Watch rating represent those loans not classified on the Company’s rating scale for problem credits, with loans with a Watch rating being monitored and updated at least quarterly by management. Substandard loans are those where a well-defined weakness has been identified that may put full collection of contractual debt at risk. Doubtful loans are those where a well-defined weakness has been identified and a loss of contractual debt is probable. Substandard and doubtful loans are monitored and updated monthly. All loan risk ratings are updated and monitored on a continuous basis. The Company generally does not risk rate consumer loans unless a default event such as bankruptcy or extended nonperformance takes place. Alternatively, standard credit scoring systems are used to assess credit risks of consumer loans.

Troubled Debt Restructurings (“TDRs”)

Loans modified under troubled debt restructurings involve granting a concession to a borrower who is experiencing financial difficulty. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance, or other actions intended to maximize collection, which generally would not otherwise be considered. Our TDRs include performing and nonperforming TDRs, which consist of loans that continue to accrue interest at the loan's original interest rate as we expect to collect the remaining principal and interest on the loan, and nonaccrual TDRs, which include loans that are in a nonaccrual status and are no longer accruing interest, as we do not expect to collect the full amount of principal and interest owned from the borrower on these loans. At the time of modification (except for loans on nonaccrual status), a TDR is classified as nonperforming TDR until a six-month payment history of principal and interest payments, in accordance with the terms of the loan modification, is sustained, at which time we move the loan to a performing status (performing TDR). If we do not expect to collect all principal and interest on the loan, the modified loan is classified as a nonaccrual TDR. All TDRs are accounted for as impaired loans and are included in our analysis of the allowance for loan and lease losses. A TDR that has been re-underwritten and renewed for a borrower who is no longer experiencing financial difficulty and which yields a market rate of interest at the time of a renewal is no longer considered a TDR.

Allowance for Loan and Lease Losses (“ALLL”) and Unfunded Commitments

The Company maintains an allowance for loan and lease losses at a level management believes is appropriate to reserve for credit losses inherent in our loan portfolio. The allowance for loan and lease losses is determined based on an ongoing evaluation, driven primarily by monitoring changes in loan risk grades, delinquencies, and other credit risk indicators, which is inherently subjective.

The Company considers the uncertainty related to certain industry sectors and the extent of credit exposure to specific borrowers within the portfolio. In addition, consideration is given to concentration risks associated with the various loan portfolios and current economic conditions that might impact the portfolio. The Company also considers changes, if any, in underwriting activities, the loan portfolio composition (including product mix and geographic, industry, or customer-specific concentrations), trends in loan performance, the level of allowance coverage relative to similar banking institutions and macroeconomic factors, such as changes in unemployment rates, gross domestic product, and consumer bankruptcy filings.

All of these estimates are susceptible to significant change. Changes to the allowance for loan and lease losses are made by charges to the provision for loan and lease losses, which is reflected in the consolidated statements of comprehensive income. Past due status is monitored as an indicator of credit deterioration. Loans that are 90 days or more past due are put on nonaccrual status unless the loan is well secured and in the process of collection. Loans deemed to be uncollectible are charged off against the allowance for loan and lease losses. Recoveries of amounts previously charged-off are credited to the allowance for loan and lease losses.

The allowance for loan and lease losses consist of reserves for probable losses that have been identified related to specific borrowing relationships that are individually evaluated for impairment (“specific reserve”), as well as probable losses inherent in our loan portfolio that are not specifically identified (“collective reserve”).

The specific reserve relates to impaired loans. A loan is impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due (interest as well as principal) according to the contractual terms of the loan agreement. Specific reserves are determined on a loan-by-loan basis based on management’s best estimate of the Company’s exposure, given the current payment status of the loan, the present value of expected payments, and the value of any underlying collateral. Impaired loans also include loans modified in troubled debt restructurings. Generally, the impairment related to troubled debt restructurings is measured based on the fair value of the collateral, less cost to sell, or the present value of expected payments relative to the unpaid principal balance. If the impaired loan is identified as collateral dependent, then the fair value of the collateral method of measuring the amount of the impairment is utilized. This method requires obtaining an independent appraisal of the collateral and applying a discount factor to the appraised value, if necessary, and including costs to sell.

Management’s estimate for collective reserves reflects losses incurred in the loan portfolio as of the consolidated balance sheet reporting date. Incurred loss estimates primarily are based on historical loss experience and portfolio mix. Incurred loss estimates may be adjusted for qualitative factors such as current economic conditions and current portfolio trends including credit quality, concentrations, aging of the portfolio, and/or significant policy and underwriting changes.

The Company maintains an ALLL for acquired impaired loans accounted for under ASC 310-30, resulting from decreases in expected cash flows arising from the periodic revaluation of these loans. Any decrease in expected cash flows in the individual loan pool is generally recognized in the current provision for loan and lease losses. Any increase in expected cash flows is generally not recognized immediately, but is instead reflected as an adjustment to the related loan or pool's yield on a prospective basis once any previously recorded provision for loan and lease loss has been recognized.

For acquired nonimpaired loans accounted for under ASC 310-20, the Company utilizes methods to estimate the required allowance for loan and lease losses similar to originated loans; the required reserve is compared to the net carrying value of each acquired nonimpaired loan (by segment) to determine if a provision is required.

While management uses the best information available to establish the allowance for loan and lease losses, future adjustments may be necessary if economic conditions differ substantially from the assumptions used in performing the estimates.

Unfunded residential mortgage loan commitments entered into in connection with mortgage loans to be held for sale are considered derivatives and are recorded at fair value and included in other liabilities on the consolidated balance sheets with changes in fair value recorded in other interest income. All other unfunded loan commitments are generally related to providing credit facilities to customers and are not considered derivatives. For purchased loans, the fair value of the unfunded credit commitments is considered in determination of the fair value of the loans recorded at the date of acquisition. Reserves for credit exposure on all other unfunded credit commitments are recorded in other liabilities on the consolidated balance sheets.

FDIC Indemnification Asset and Clawback Liability

In conjunction with a Federal Deposit Insurance Corporation (“FDIC”)-assisted transaction of TierOne Bank in 2010, the Company entered into two loss share agreements with the FDIC, one covering certain single family residential mortgage loans with the claim period ending June 2020 and one covering commercial loans and other assets, in which the claim period ended in June 2015. The agreements cover a portion of realized losses on loans, foreclosed real estate and certain other assets. The Company has recorded assets on the consolidated balance sheets (i.e. indemnification assets) representing estimated future amounts recoverable from the FDIC.

Fair values of loans covered by the loss sharing agreements at the acquisition date were estimated based on projected cash flows available based on the expected probability of default, default timing and loss given default, the expected reimbursement rates (generally 80%) from the FDIC and other relevant terms of the loss sharing agreements. The initial fair value was established by discounting these expected cash flows with a market discount rate for instruments with like maturity and risk characteristics.

The loss share assets are measured separately from the related loans and foreclosed real estate and recorded as an FDIC indemnification asset on the consolidated balance sheets because they are not contractually embedded in the loans and are not transferable with the loans should the Company choose to dispose of them. Subsequent to the acquisition date, reimbursements received from the FDIC for actual incurred losses reduce the carrying amount of the loss share assets. Reductions to expected losses on covered assets, to the extent such reductions to expected losses are the result of an improvement to the actual or expected cash flows from the covered assets, also reduce the carrying amount of the loss share assets. The rate of accretion of the indemnification asset discount included in interest income slows to mirror the accelerated accretion of the loan discount. Additional expected losses on covered assets, to the extent such expected losses result in the recognition of an allowance for loan and lease losses, increase the carrying amount of the loss share assets. A related increase in the value of the indemnification asset up to the amount covered by the FDIC is calculated based on the reimbursement rates from the FDIC and is included in other noninterest income. The corresponding loan accretion or amortization is recorded as a component of interest income on the consolidated statements of comprehensive income. Although these assets are contractual receivables from the FDIC, there are no contractual interest rates.

As part of the loss sharing agreements, the Company also assumed a liability (“FDIC Clawback Liability”) to be paid within 45 days subsequent to the maturity or termination of the loss sharing agreements that is contingent upon actual losses incurred over the life of the agreements relative to expected losses considered in the consideration paid at acquisition date and the amount of losses reimbursed to the Company under the loss sharing agreements. The liability was recorded at fair value as of the acquisition date. The fair value was based on a discounted cash flow calculation that considered the formula defined in the loss sharing agreements and projected losses. The difference between the fair value at acquisition date and the projected losses is amortized through other noninterest expense. As projected losses and reimbursements are updated, as described above, the FDIC Clawback Liability is adjusted and a gain or loss is recorded in other noninterest expense.

Loan Servicing Rights

The Company records a servicing asset for contractually separated servicing from the underlying mortgage loans. Fair value is based on market prices for comparable mortgage servicing contracts, when available or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The asset is amortized into mortgage banking income, net on the consolidated statement of comprehensive income in proportion to and over the period of estimated net servicing income.

Loan servicing rights are evaluated for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is determined by stratifying rights into groupings based on characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists, a reduction of the allowance may be recorded as an increase to noninterest income. If the Company determines the impairment to be permanent, the valuation is written off against the loan servicing rights, which results in a new amortized balance. Changes in the valuation allowance are reported in mortgage banking income, net in the consolidated statement of comprehensive income. The fair value of loan servicing rights is subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Estimating future cash flows on the underlying mortgages is a difficult analysis and requires judgment based on the best information available. Based on the Company's analysis of loan servicing rights, a valuation allowance of $0.2 million was recorded at June 30, 2016.

Servicing fee income, which is reported in noninterest income, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding balance or a fixed amount per loan and are recorded as income as earned. The amortization of loan servicing rights is netted against mortgage banking income, net in the statement of consolidated comprehensive income.

Goodwill

Goodwill represents the cost in excess of the fair value of net assets acquired (including identifiable intangibles) in transactions accounted for as business acquisitions. Goodwill is evaluated annually for impairment or more frequently if events and circumstances exist that indicates that a goodwill impairment test should be performed. The Company performs its impairment evaluation as of June 30 of each fiscal year. If the implied fair value of goodwill is lower than its carrying amount, goodwill impairment is indicated and goodwill is written down to its implied fair value. Subsequent increases in goodwill are not recognized in the consolidated financial statements. No goodwill impairment was recognized during the three and nine months ended June 30, 2016 and 2015.

Core Deposits and Other Intangibles

Intangible assets consist of core deposits, brand intangible, customer relationships, and other intangibles. Core deposits represent the identifiable intangible value assigned to core deposit bases arising from purchase acquisitions. Brand intangible represents the value associated with the Bank charter. Customer relationships intangible represents the identifiable intangible value assigned to customer relationships arising from a purchase acquisition. Other intangibles represent contractual franchise arrangements under which the franchiser grants the franchisee the right to perform certain functions within a designated geographical area. The methods and lives used to amortize intangible assets are as follows:

Intangible	Method	Years
Core deposit	Straight-line or effective yield	5 - 10
Brand intangible	Straight-line	15
Customer relationships	Straight-line	8.5
Other intangibles	Straight-line	1.25 - 9.33

Intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. No intangible asset impairments were recognized during the periods ended June 30, 2016 and 2015.

Derivatives

The Company maintains an overall interest rate risk management strategy that permits the use of derivative instruments to modify exposure to interest rate risk. The Company enters into interest rate swap contracts to offset the interest rate risk associated with borrowers who lock in long-term fixed rates (greater than or equal to 5 years to maturity) through a fixed rate loan. These contracts do not qualify for hedge accounting. Generally, under these swaps, the Company agrees with various swap counterparties to exchange the difference between fixed-rate and floating-rate interest amounts based upon notional principal amounts. These interest rate derivative instruments are recognized as assets and liabilities on the consolidated balance sheets and measured at fair value, with changes in fair value reported in net realized and unrealized gain (loss) on derivatives. Since each fixed rate loan is paired with an offsetting derivative contract, the impact to net income is minimized.

The Company enters into forward interest rate lock commitments on mortgage loans to be held for sale, which are commitments to originate loans whereby the interest rate on the loan is determined prior to funding. The Company also has corresponding forward sales contracts related to these interest rate lock commitments. Both the mortgage loan commitments and the related sales contracts are considered derivatives and are recorded at fair value with changes in fair value recorded in noninterest income.

Stock Based Compensation

Restricted and performance-based stock units/awards are classified as equity awards and accounted for under the Treasury method. Compensation expense for non-vested stock units/awards is based on the fair value of the award on the measurement date, which, for the Company, is the date of the grant and is recognized ratably over the vesting or performance period of the award. The fair value of non-vested stock units/awards is generally the market price of the Company's stock on the date of grant.

Income Taxes

The Company was required to file a consolidated income tax return with National Americas Investment, Inc. ("NAI") (a wholly owned indirect subsidiary of NAB) until NAI's dissolution on October 17, 2014. Income taxes are allocated pursuant to a tax-sharing arrangement, whereby the Company will pay federal and state income taxes as if it were filing on a stand-alone basis. Income tax expense includes two components: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over income. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods.

Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.

Tax benefits related to uncertain tax positions are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term "more likely than not" means a likelihood of more than 50 percent; the terms "examined" and "upon examination" also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information.

The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment.

Transfers of Financial Assets

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company-put presumptively beyond reach of the Company and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.

Securities sold under agreements to repurchase are accounted for as collateralized financing transactions and are recorded at amounts at which the securities were financed, plus accrued interest.

Defined Benefit Plan

The Company assumed plan sponsorship of the HF Financial Corp. Pension Plan during the quarter as part of the HF Financial acquisition. Defined benefit pension obligation and related costs are calculated using actuarial concepts and measurements. Three critical assumptions, the discount rate, the expected long-term rate of return on plan assets, and mortality rates are important elements of expense and/or benefit obligation measurements. Other assumptions involve employee demographic factors such as retirement patterns and turnover. The Company evaluates all assumptions annually. For accounting purposes, mortality assumptions at June 30, 2016 were based on the RP-2014 mortality tables and the MP 2015 projection scales.

The discount rate enables the Company to state expected future benefit payments as a present value on the measurement date. The Company determined the discount rate at June 30, 2016 by utilizing the standard duration index from the Citi Pension Discount Curve and Liability Index. A lower discount rate increases the present value of benefit obligations and increases pension expense.

To determine expected long-term rate of return on defined benefit pension plan assets, the Company considers the current asset allocation of the defined benefit pension plan, as well as historical and expected returns on each asset class. A lower expected rate of return on defined pension plan assets will increase pension expense.

The Company recognizes the over- or under-funded status of a plan as an other asset or other liability in the consolidated balance sheet as measured by the difference between the fair value of the plan assets and the projected benefit obligation. When recorded, unrecognized prior service costs and actuarial gains and losses are recognized as a component of accumulated other comprehensive income (loss).

Revenue Recognition

The Company recognizes revenue as it is earned based on contractual terms, as transactions occur, or as services are provided and collectability is reasonably assured. Certain specific policies related to service charges and other fees include the following:

Deposit Service Charges

Service charges on deposit accounts are primarily fees related to customer overdraft events and not sufficient funds fees, net of any refunded fees, and are recognized as transactions occur and services are provided. Service charges on deposit accounts also relate to monthly fees based on minimum balances, and are earned as transactions occur and services are provided.

Interchange Fees

Interchange fees include interchange income from consumer debit card transactions processed through card association networks. Interchange income is a fee paid by a merchant bank to the card-issuing bank through the interchange network. Interchange fees are set by the card association networks and are based on cardholder purchase volumes.

Wealth Management Fees

Wealth management fees include commission income from financial planning, investment management and insurance operations.

Comprehensive Income

Comprehensive income consists of net income and other comprehensive income, net of applicable income taxes. Other comprehensive income (loss) consists entirely of unrealized appreciation (depreciation) on available-for-sale securities.

Subsequent Events

The Company has evaluated all events or transactions that occurred through the date the Company issued these financial statements. During this period, the Company did not have any material recognizable or non-recognizable subsequent events other than outlined below.

On July 28, 2016, the board of directors of the Company declared a dividend of $0.14 per common share payable on August 24, 2016 to stockholders of record as of close of business on August 12, 2016.

Accounting Changes and Error Corrections [Abstract]

New Accounting Pronouncements

New Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which addresses timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires institutions to measure all expected credit losses related to financial assets measured at amortized costs with an expected loss model based on historical experience, current conditions and reasonable and supportable forecasts relevant to affect the collectibility of the financial assets, which is referred to as the current expected credit loss (CECL) model. The ASU requires enhanced disclosures, including qualitative and quantitative requirements, to help understand significant estimates and judgments used in estimating credit losses, as well as provide additional information about the amounts recorded in the financial statements. ASU 2016-13 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted after December 15, 2018. The amendment requires the use of the modified retrospective approach for adoption. The Company is currently evaluating the potential impact of ASU 2016-13 on our financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Based Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which addresses 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. ASU 2016-09 is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Earlier application is permitted. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The Company is currently evaluating the potential impact of ASU 2016-09 on our financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires that lessees recognize the assets and liabilities arising from leases on the balance sheet. ASU 2015-16 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the potential impact of ASU 2016-02 on our financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities, which addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the potential impact of ASU 2016-01 on our financial statements.

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805) - Simplifying the Accounting for Measurement-Period Adjustments, which requires that adjustments to provisional amounts that are identified during the measurement period of a business combination be recognized in the reporting period in which the adjustment amounts are determined. Furthermore, the income statement effects of such adjustments, if any, must be calculated as if the accounting had been completed at the acquisition date. The portion of the amount recorded in current-period earnings that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. Under previous guidance, adjustments to provisional amounts identified during the measurement period are to be recognized retrospectively. ASU 2015-16 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Earlier application is permitted for financial statements that have not been issued, therefore the Company has elected to early adopt this ASU as of and for its quarter ended June 30, 2016. The adoption of ASU 2015-16 in the third quarter of 2016 did not have a material impact on the Company's consolidated balance sheet or consolidated statement of comprehensive income. See also Note 3 to these consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which implements a common revenue standard that clarifies the principles for recognizing revenue. 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 and services. In August 2015, the FASB issued ASU No. 2015-14 which deferred the effective date of ASU No. 2014-09 to annual reporting periods beginning after December 15, 2017. In March 2016, the FASB issued ASU No. 2016-08, which intends to improve the operability and understandability of the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU No. 2016-10, which clarifies guidance pertaining to the identification of performance obligations and the licensing implementation. In May 2016, the FASB issued ASU Nos. 2016-11 and 2016-12, which further clarify guidance and provide practical expedients related to the adoption of ASU No. 2014-09. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is currently evaluating the potential impact of these standards on our financial statements.

Acquisition Activity

Acquisition Activity

On May 16, 2016, the Company acquired by merger 100% of HF Financial Corp ("HF Financial"), the holding company of Home Federal Bank. Under terms of the agreement, HF Financial's stockholders had the right to receive for each share of HF Financial common stock, at their election (but subject to proration in the event cash or stock is oversubscribed), either (i) 0.6500 share of the Company's common stock, or (ii) $19.50 in cash. The total consideration was prorated as necessary to ensure that 24.29% of the total outstanding shares of HF Financial common stock were exchanged for cash and 75.71% of the total outstanding shares of HF Financial common stock were exchanged for shares of the Company's common stock. Total merger consideration of $142.0 million was paid by the Company in the acquisition, which resulted in goodwill of $40.7 million, as shown in the table below. With this acquisition, the Company expanded its presence into North Dakota and Minnesota through the addition of 23 bank offices and experienced in-market teams. The Company projects increased revenues from additional locations and customers and cost savings will be recognized in future periods through the elimination of redundant operations. The following summarizes consideration paid and an allocation of purchase price to net assets acquired.

	Number of Shares	Amount
(In thousands)
Equity consideration:
Common stock issued	3,448,119	$	107,478
Non-equity consideration:
Cash		34,487
Total consideration paid		141,965
Fair value of net assets acquired including identifiable intangible assets		101,312
Goodwill		$	40,653

Goodwill of $40.7 million arising from the acquisition arose as a result of consideration in excess of net assets acquired. The amount of goodwill that is expected to be deductible for income tax purposes is $0.0 million. The fair value of intangible assets created in the acquisition was $7.9 million related to core deposits and other intangible assets.

The following table summarizes the assets acquired and liabilities assumed which were recorded on the consolidated balance sheet as of the date of merger of HF Financial:

(In thousands)	Fair Value
Identifiable assets acquired:
Cash and due from banks	$	18,818
Investment securities	165,052
Net loans	863,741
Premises and equipment	19,220
Accrued interest receivable	4,117
Other repossessed property	4
Intangible assets	7,877
Loan servicing rights	6,573
Other assets	36,639
Total identifiable assets acquired	$	1,122,041
Liabilities assumed:
Deposits	$	863,121
FHLB advances and other borrowings	115,881
Subordinated debentures	21,110
Other liabilities	20,617
Total liabilities assumed	1,020,729
Fair value of net identifiable assets acquired	101,312
Net purchase price	141,965
Goodwill	$	40,653

The Company accounted for the aforementioned business combination under the acquisition method in accordance with ASC Topic 805, Business Combinations. Accordingly, the purchase price is allocated to the fair value of the assets acquired and liabilities assumed as of the date of acquisition. The foregoing purchase price allocations on the acquisition are preliminary and will be finalized upon the receipt of final valuations on certain assets and liabilities. Upon receipt of final fair value estimates, which must be within one year of the acquisition date, the Company will make any final adjustments to the purchase price allocation and retrospectively adjust any goodwill recorded. Material adjustments to acquisition date estimated fair values would be recorded in the reporting period in which the adjustment amounts are determined. Information regarding the Company’s loan discount and related deferred tax asset, core deposit intangible asset and related deferred tax liability, as well as income taxes payable and the related deferred tax balances recorded in the acquisition may be adjusted as the Company refines its estimates. Determining the fair value of assets and liabilities, particularly illiquid assets and liabilities, is a complicated process involving significant judgment regarding estimates and assumptions used to calculate estimated fair value. Fair value adjustments based on updated estimates could materially affect the goodwill recorded on the acquisition. The Company may incur losses on the acquired loans that are materially different from losses the Company originally projected.

The results of the merged HF Financial operations are presented within the Company’s consolidated financial statements from the acquisition date. The disclosure of HF Financial's post-acquisition revenue and net income is not practical due to the combining of HF Financial’s operations with and into the Company as of the acquisition date. Acquisition-related transaction expenses associated with the HF Financial acquisition totaled $12.2 million and $12.9 million during the three and nine months ended June 30, 2016, respectively, and $0.0 million for the three and nine months ended June 30, 2015.

Supplemental unaudited pro forma information

The following unaudited pro forma combined results of operations of the Company and HF Financial presents results as if the acquisition had been completed as of the beginning of each period indicated. The unaudited pro forma combined results of operations are presented solely for information purposes and are not intended to represent or be indicative of the consolidated results of operations that the Company would have reported had this transaction been completed as of the dates and for the periods presented, nor are they necessarily indicative of future results. In particular, no adjustments have been made to eliminate the amount of HF Financial's provision for loan and lease losses incurred prior to the acquisition date that would not have been necessary had the acquired loans been recorded at fair value as of the beginning of each period indicated. In accordance with Article 11 of SEC Regulation S-X, transaction costs directly attributable to the acquisition have been excluded.

Proceeds from sales of securities available for sale were $120.9 million and $0.0 million for the three months ended June 30, 2016 and 2015, respectively, and $145.9 million and $55.1 million for the nine months ended June 30, 2016 and 2015, respectively. Gross gains (pre-tax) of $0.1 million and $0.0 million and gross losses (pre-tax) of $0.0 million and $0.0 million were realized on the sales for the three months ended June 30, 2016 and 2015, respectively. Gross gains (pre-tax) of $0.2 million and $0.6 million and gross losses (pre-tax) of $0.0 million and $0.5 million were realized on the sales for the nine months ended June 30, 2016 and 2015, respectively, using the specific identification method. The Company recognized an other-than-temporary impairment in net loss on sale of securities in the consolidated statements of comprehensive income of $0.0 million and $0.4 million on two security holdings attributable to credit for the three and nine months ended June 30, 2016. There was no other-than-temporary impairment recognized for the three and nine months ended June 30, 2015.

Securities with an estimated fair value of approximately $1.08 billion and $894.3 million at June 30, 2016 and September 30, 2015, respectively, were pledged as collateral on public deposits, securities sold under agreements to repurchase, and for other purposes as required or permitted by law. The counterparties do not have the right to sell or pledge the securities the Company has pledged as collateral.

As detailed in the following tables, certain investments in debt securities, which are approximately 15% and 36% of the Company’s investment portfolio at June 30, 2016 and September 30, 2015, respectively, are reported in the consolidated financial statements at an amount less than their amortized cost. Based on evaluation of available evidence, including recent changes in market interest rates, credit rating information, implicit or explicit government guarantees, and information obtained from regulatory filings, management believes the declines in fair value of these securities are temporary. As the Company does not intend to sell the securities and it is not more likely than not that the Company will be required to sell the securities before the recovery of their amortized cost basis, which may be maturity, the Company does not consider the securities to be other-than-temporarily impaired at June 30, 2016 or September 30, 2015.

The following table presents the Company’s gross unrealized losses and approximate fair value in investments, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position (in thousands):

Troubled Debt Restructurings

Included in certain loan categories in the impaired loans are troubled debt restructurings (“TDRs”) that were classified as impaired. These TDRs do not include purchased credit impaired loans. When the Company grants concessions to borrowers such as reduced interest rates or extensions of loan periods that would not be considered other than because of borrowers’ financial difficulties, the modification is considered a TDR. Specific reserves included in the allowance for loan and lease losses for TDRs were $10.0 million and $3.6 million at June 30, 2016 and September 30, 2015, respectively. Commitments to lend additional funds to borrowers whose loans were modified in a TDR were $0.2 million and $2.3 million as of June 30, 2016 and September 30, 2015, respectively.

The following table presents the recorded value of the Company’s TDR balances as of June 30, 2016 and September 30, 2015 (in thousands):

The Company maintains an ALLL for acquired loans accounted for under ASC 310-30 as a result of impairment to loan pools arising from the periodic re-valuation of these loans. Any impairment in the individual pool is generally recognized in the current period as provision for loan and lease losses. Any improvement in the estimated cash flows, is generally not recognized immediately, but is instead reflected as an adjustment to the related loan pools yield on a prospective basis once any previously recorded impairment has been recaptured.

The ALLL for ASC 310-30 loans totaled $2.1 million at June 30, 2016, compared to $2.8 million at September 30, 2015. During the three and nine month period ended June 30, 2016, loan pools accounted for under ASC 310-30 had a net reversal of provision of $0.4 million and $0.6 million, respectively, as a result of increases in expected cash flows. Net provision reversals for the three and nine month period ended June 30, 2015 totaled $0.6 million and $1.2 million, and were driven a result of increases in expected cash flows in the residential real estate pool.

For acquired loans not accounted for under ASC 310-20 (purchased non-credit impaired), the Company utilizes specific and collective reserve calculation methods similar to originated loans. The required ALLL for these loans is included in the individually evaluated for impairment bucket of the ALLL if the loan is rated substandard or worse, and in the collectively evaluated for impairment bucket for pass rated loans.

The reserve for unfunded loan commitments was $0.5 million at June 30, 2016 and $0.4 million at September 30, 2015 and is recorded in other liabilities on the consolidated balance sheets.

Accounting for Certain Loans Acquired with Deteriorated Credit Quality

Accounting for Certain Loans Acquired with Deteriorated Credit Quality

Accounting for Certain Loans Acquired with Deteriorated Credit Quality

In June 2010 and May 2016, the Company acquired certain loans that had deteriorated credit quality (ASC 310-30 loans). Loan accounting specific to these purchased credit impaired loans addresses differences between contractual cash flows expected to be collected from the initial investment in loans if those differences are attributable, at least in part, to credit quality. Several factors were considered when evaluating whether a loan was considered a purchased credit impaired loan, including the delinquency status of the loan, updated borrower credit status, geographic information, and updated loan-to-values (“LTV”). U.S. GAAP allows purchasers to aggregate purchased credit impaired loans acquired in the same fiscal quarter in one or more pools, provided that the loans have common risk characteristics. A pool is then accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows.

Loan pools are periodically reassessed to determine expected cash flows. In determining the expected cash flows, the timing of cash flows and prepayment assumptions for smaller, homogeneous loans are based on statistical models that take into account factors such as the loan interest rate, credit profile of the borrowers, the years in which the loans were originated, and whether the loans are fixed or variable rate loans. Prepayments may be assumed on large individual loans that consider similar prepayment factors listed above for smaller homogeneous loans. The re-assessment of purchased credit impaired loans resulted in the following changes in the accretable yield during the three and nine months ended June 30, 2016 and 2015 (in thousands):

	Three Months Ended June 30,						Nine Months Ended June 30,
	2016			2015			2016			2015

Balance at end of period	$	40,976		$	46,889		$	40,976		$	46,889

The reclassification from nonaccretable difference noted in the table above represents instances where specific pools of loans are expected to perform better over the remaining lives of the loans than expected at the prior re-assessment date. The reclassification to nonaccretable difference noted in the table above represents instances where specific pools of loans are estimated to have a shortfall in the expected future cash flows compared to the contractual cash flows at the prior re-assessment date.

The following table provides purchased credit impaired loans at June 30, 2016 and September 30, 2015 (in thousands):

2 Represents the book balance of loans acquired with deteriorated credit quality.

3 Represents the book balance of loans acquired with deteriorated credit quality net of the related allowance for loan and lease losses.

Due to improved cash flows of the purchased credit impaired loans, the reductions to allowance recognized on previous impairments were $0.4 million and $0.9 million for the three months ended June 30, 2016 and 2015, respectively and $0.6 million and $1.9 million for the nine months ended June 30, 2016 and 2015, respectively.

FDIC Indemnification Asset

FDIC Indemnification Asset

Under the terms of the purchase and assumption agreement with the FDIC with regard to the TierOne Bank acquisition, the Company is reimbursed for a portion of the losses incurred on covered assets. As covered assets are resolved, whether it be through repayment, short sale of the underlying collateral, the foreclosure on or sale of collateral, or the sale or charge-off of loans or OREO, any differences between the carrying value of the covered assets versus the payments received during the resolution process, that are reimbursable by the FDIC, are recognized as reductions in the FDIC indemnification asset. Any gains or losses realized from the resolution of covered assets reduce or increase, respectively, the amount recoverable from the FDIC. The following table represents a summary of the activity related to the FDIC indemnification asset for the three and nine months ended June 30, 2016 and 2015 (in thousands):

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

In the normal course of business, the Company uses interest rate swaps to manage its interest rate risk and market risk in accommodating the needs of its customers. Also, the Company enters into interest rate lock commitments on mortgage loans to be held for sale, with corresponding forward sales contracts related to these interest rate lock commitments.

Derivative instruments are recognized as either assets or liabilities in the accompanying consolidated financial statements and are measured at fair value.

The following table summarizes the notional amounts and estimated fair values of the Company’s derivative instruments at June 30, 2016 and September 30, 2015 (in thousands):

	June 30, 2016
	Notional Amount		Balance Sheet Location	Positive Fair Value		Negative Fair Value

Mortgage loan forward sale contracts	36,655		Liabilities	—		(95		)

As with any financial instrument, derivative financial instruments have inherent risk including adverse changes in interest rates. The Company’s exposure to derivative credit risk is defined as the possibility of sustaining a loss due to the failure of the counterparty to perform in accordance with the terms of the contract. Credit risks associated with interest rate swaps are similar to those relating to traditional on-balance sheet financial instruments. The Company manages interest rate swap credit risk with the same standards and procedures applied to its commercial lending activities. Amounts due from swap counterparties to reclaim cash collateral under the interest rate swap master netting arrangements have not been offset against the derivative balances.

Credit-risk-related contingent features

The Company has agreements with its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well/adequately capitalized institution, then the counterparty has the right to terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of June 30, 2016, the termination value of derivatives in a net liability position related to these agreements was $93.4 million which includes accrued interest but excludes any adjustment fornonperformance risk. The Company has minimum collateral posting thresholds with its derivative counterparties and as of June 30, 2016, the Company had posted $101.6 million in eligible collateral.

The effect of derivatives on the consolidated statements of comprehensive income for the three and nine months ended June 30, 2016 and 2015 (in thousands) was as follows:

Netting of Derivatives

The Company has various financial assets and financial liabilities that are subject to enforceable master netting agreements or similar agreements. The Company has entered into an ISDA master netting arrangement with various swap counterparties. Under the terms of the master netting arrangements, all transactions between the Company and the counterparty constitute a single business relationship such that in the event of default, the non-defaulting party is entitled to set off claims and apply property held by that party in respect of any transaction against obligations owed. Any payments, deliveries, or other transfers may be applied against each other and netted.

The following tables (in thousands) present the Company's total gross derivative assets and liabilities at June 30, 2016 and September 30, 2015, which are adjusted on an aggregate basis, where applicable, to take into consideration the effects of legally enforceable master netting agreements for the net reported amount in the consolidated balance sheets. These amounts are offset on the consolidated balance sheets.

Fair Value Disclosures [Abstract]

The Fair Value Option For Certain Loans

The Fair Value Option For Certain Loans

The Company has elected to measure certain long-term loans and written loan commitments at fair value to assist in managing the interest rate risk for longer-term loans. This fair value option was elected upon the origination of these loans. Interest income is recognized in the same manner as interest on non-fair value loans.

See Note 19 for additional disclosures regarding the fair value of the fair value option loans and written loan commitments.

Long-term loans and written loan commitments for which the fair value option has been elected had a net favorable difference between the aggregate fair value and the aggregate unpaid loan principal balance and written loan commitment amount of approximately $83.0 million and $47.8 million at June 30, 2016 and September 30, 2015, respectively. The total unpaid principal balance of these long-term loans was approximately $1.07 billion and $1.07 billion at June 30, 2016 and September 30, 2015, respectively. The fair value of these loans and written loan commitments is included in total loans in the consolidated balance sheets and are grouped with commercial non real estate, commercial real estate, and agricultural loans in Note 5. The fair value of these written loan commitments was not material at June 30, 2016 and September 30, 2015, respectively. As of June 30, 2016 and September 30, 2015, there were loans with a fair value of $9.0 million and $1.5 million, respectively, which were greater than 90 days past due or in nonaccrual status with an unpaid principal balance of $11.0 million and $1.7 million, respectively.

Changes in fair value for items for which the fair value option has been elected and the line items in which these changes are reported within the consolidated statements of comprehensive income are as follows for the three and nine months ended June 30, 2016 and 2015 (in thousands):

	For the Three Months Ended										For the Nine Months Ended

For long-term loans and written loan commitments, $2.7 million and $0.0 million for the three months ended June 30, 2016 and 2015, respectively, and $2.3 million and $0.5 million for the nine months ended June 30, 2016 and 2015, respectively, of the total change in fair value is attributable to changes in specific credit risk. The gains or losses attributable to changes in instrument-specific credit risk were determined based on an assessment of existing market conditions and credit quality of the underlying loan for the specific portfolio of loans.

Amortization of servicing rights is adjusted each quarter based upon analysis of portfolio attributes and factors, including an evaluation of historical prepayment activity and prospective industry consensus data. An independent third party is utilized to calculate the amortization and valuation based upon specific loan characteristics, prepayment speeds generated from a validation model utilizing both empirical and market derived data and discount rates. At June 30, 2016, the constant prepayment rates (CPR) used to calculate the amortization averaged 16.4%. For valuation purposes, an average discount rate of 11.6% was utilized at June 30, 2016. Based on the Company's analysis of mortgage servicing rights, a $0.2 million valuation reserve was recorded at June 30, 2016 and $0.0 million at June 30, 2015.

Subordinated Debentures and Subordinated Notes Payable

Junior Subordinated Deferrable Interest Debentures

The Company has caused seven trusts to be created (or assumed as part of the HF Financial and Sunstate Bank acquisitions) that have issued and outstanding 78,400 shares, $1,000 par value, of Company Obligated Mandatorily Redeemable Preferred Securities (the "Preferred Securities"). These seven trusts were established and exist for the sole purpose of issuing the Preferred Securities and investing the proceeds in junior subordinated deferrable interest debentures (the "Debentures") issued by the Company. The Debentures constitute the sole assets of the seven trusts. The Preferred Securities provide for cumulative cash distributions calculated at a rate based on three-month LIBOR plus a range from 1.48% to 3.35% adjusted quarterly. The Company may, at one or more times, defer interest payments on the Debentures for up to 20 consecutive quarters following suspension of dividends on all capital stock, but not beyond the respective maturity date. At the end of any deferral period, all accumulated and unpaid interest must be paid. The Debentures have redemption dates ranging from January 7, 2033 to October 1, 2037; however, the Company has the option to shorten the respective maturity date for all seven Preferred Securities as the call option date has passed. Holders of the Preferred Securities have no voting rights. The Preferred Securities are unsecured and rank junior in priority of the payment to all of the Company's indebtedness and senior to the Company's common and preferred stock. The trusts’ ability to pay amounts due on the Preferred Securities is solely dependent upon the Company making payment on the related Debentures. The Company’s obligation under the Debentures and relevant trust agreements constitute a full, irrevocable, and unconditional guarantee on a subordinated basis by it of the obligations of the trusts under the Preferred Securities.

For regulatory purposes the Debentures qualify as elements of capital. $77.1 million and $56.1 million of Debentures were eligible for treatment as Tier 1 capital, respectively, as of June 30, 2016 and 2015.

Relating to the trusts, the Company held as assets $2.5 million and $1.7 million in common shares at June 30, 2016 and 2015, respectively, which are included in other assets on the consolidated balance sheets.

Subordinated Notes Payable

In 2015, the Company issued $35.0 million of 4.875% fixed-to-floating rate subordinated notes that mature on August 15, 2025 through a private placement. The notes, which qualify as Tier 2 capital under capital rules in effect at June 30, 2016, have an interest rate of 4.875% per annum, payable semi-annually on each February 15 and August 15, which commenced on February 15, 2016 until August 15, 2020. From August 15, 2020, to but excluding the maturity date or date of earlier redemption, the notes will bear interest at a rate per annum equal to to three-month LIBOR for the related interest period plus 3.15%, payable quarterly on each November 15, February 15, April 15 and August 15. The notes are subordinated in right of payment to all of the Company's senior indebtedness and effectively subordinated to all existing and future debt and all other liabilities of the Company's subsidiary bank. The Company may elect to redeem the notes (subject to regulatory approval), in whole or in part, on any early redemption date which is any interest payment date on or after August 15, 2020 at a redemption price equal to 100% of the principal amount plus any accrued and unpaid interest. Other than on an early redemption date, the notes cannot be accelerated except in the event of bankruptcy or the occurrence of certain other events of bankruptcy, insolvency or reorganization. Proceeds from the private placement of subordinated notes repaid outstanding subordinated debt.

The Company participates in a multiple employer 401(k) profit sharing plan (the Plan). All employees are eligible to participate, beginning with the first day of the month coincident with or immediately following the completion of one year of service and having reached the age of 21. In addition to employee contributions, the Company may contribute discretionary amounts for eligible participants. Contribution rates for participating employees must be equal.

Defined Benefit Plan

The Company acquired a noncontributory (cash balance) defined benefit pension plan from HF Financial which covers employees of HF Financial and its wholly-owned subsidiaries. Effective July 1, 2015, the Company froze the plan which eliminates future contributions for qualified individuals. The plan has not been terminated, so the plan continues to exist with related benefit obligations and plan assets for those vested within the plan.

Stock-Based Compensation

Stock-Based Compensation

On September 26, 2014, the Board of Directors adopted, and on October 10, 2014, NAB, at that time our controlling shareholder, approved the Great Western Bancorp, Inc. 2014 Omnibus Incentive Compensation Plan (the “2014 Plan”), the Great Western Bancorp, Inc. 2014 Non-Employee Director Plan (the “2014 Director Plan”), and the Great Western Bancorp, Inc. Executive Incentive Compensation Plan (the “Bonus Plan”), collectively ("the Plans"), which provide for the issuance of restricted share units and performance based share units to certain officers, employees and directors of the Company. The Plans were primarily established to enhance the Company’s ability to attract, retain and motivate employees. The Company’s Board of Directors, the Compensation Committee of the Board of Directors ("Compensation Committee"), or executive management upon delegation of the Compensation Committee has exclusive authority to select the employees and others, including directors, to receive the awards and to establish the terms and conditions of each award made pursuant to the Company’s stock-based compensation plans.

Stock units issued under the Company’s restricted and performance based stock plans may not be sold or otherwise transferred until the vesting period (typically 3 years) has been met and/or performance objectives have been obtained. During the vesting periods, participants do not have voting rights and dividends are accumulated until the time upon which the award vests. Upon specified events, as defined in the Plans, stock unit awards that have not vested and/or performance hurdles that have not been met will be forfeited.

Based on the substantive terms of each award, restricted and performance-based awards are classified as equity awards and accounted for under the Treasury method. The fair value of equity-classified awards is based on the market price of the stock on the measurement date and is amortized as compensation expense on a straight-line basis over the vesting or performance period.

Stock based compensation is recognized based on the number of awards that are ultimately expected to vest. Forfeitures are estimated based on historical turnover experience of qualified employees. For performance-based stock awards, an estimate is made of the number of shares expected to vest as a result of actual performance against the performance targets to determine the amount of compensation expense to be recognized. The estimate is reevaluated quarterly and total compensation expense is adjusted for any change in the current period. Stock-based compensation expense is included in salaries and employee benefits expense in the consolidated statements of comprehensive income. For the three months ended June 30, 2016 and 2015, stock compensation expense was $0.9 million and $0.3 million, respectively. For the nine months ended June 30, 2016 and 2015, stock compensation expense was $2.7 million and $1.0 million, respectively. Related income tax benefits recognized were $0.3 million and $0.1 million for the three months ended June 30, 2016 and 2015, respectively and $1.0 million and $0.4 million for the nine months ended June 30, 2016 and 2015, respectively.

The following is a summary of the Plans’ restricted share and performance-based stock award activity as of June 30, 2016 and September 30, 2015:

	June 30, 2016				September 30, 2015

Performance shares, end of period	239,902		$	20.29	211,026		$	18.00

The number of performance shares granted is reflected in the above table at the 100% target performance level. The actual performance-based award payouts will vary based on the achievement of the pre-established targets and can range from 0% to 150% of the target amount. The outstanding number of performance shares reflected in the table represents the number of shares expected to be awarded based on estimated achievement of the goals as of June 30, 2016. The maximum number of performance-based shares that could be issued if performance is attained at 150% of target based on the grants made to date was approximately 359,853 shares at June 30, 2016.

As of June 30, 2016, there was $4.9 million of unrecognized compensation cost related to nonvested restricted stock awards expected to be recognized over a period of 2.4 years. The fair value of the vested, but not issued stock awards at June 30, 2016, was $0.8 million.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value guidance also establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance describes three levels of inputs that may be used to measure fair value are as follows:

Level 1    Quoted prices in active markets for identical assets or liabilities

Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities

Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities

Level 1 inputs are considered to be the most transparent and reliable and Level 3 inputs are considered to be the least transparent and reliable. The Company assumes the use of the principal market to conduct a transaction of each particular asset or liability being measured and then considers the assumptions that market participants would use when pricing the asset or liability. Whenever possible, the Company first looks for quoted prices for identical assets or liabilities in active markets (Level 1 inputs) to value each asset or liability. However, when inputs from identical assets or liabilities on active markets are not available, the Company utilizes market observable data for similar assets and liabilities. The Company maximizes the use of observable inputs and limits the use of unobservable inputs to occasions when observable inputs are not available. The need to use unobservable inputs generally results from the lack of market liquidity of the actual financial instrument or of the underlying collateral. Although in some instances, third party price indications may be available, limited trading activity can challenge the observability of these quotations.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Following is a description of the valuation methodologies and inputs used for assets and liabilities measured at fair value on a recurring basis and recognized in the accompanying consolidated balance sheets, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy.

Securities Available for Sale

Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include U.S. Treasury securities and U.S. Agency securities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows and classified as Level 2 securities. Level 2 securities include agency mortgage-backed, states and political subdivisions, corporate debt, and other securities. Where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy.

Interest Rate Swaps and Loans

Interest rate swaps are valued by the Company's Swap Dealers using LIBOR rates. The fair value of loans accounted for under the fair value option represents the net carrying value of the loan, plus the equal and opposite amount of the value of the swap needed to hedge the interest rate risk and an adjustment for credit risk based on our assessment of existing market conditions for the specific portfolio of loans. This is used due to the strict prepayment penalties put in the loan terms to cover the cost of exiting the hedge of the loans in the case of early prepayment or termination. The adjustment for credit risk on loans accounted for under the fair value option is not significant to the overall fair value of the loans. The fair values estimated by the Company's Swap Dealers use interest rates that are observable or that can be corroborated by observable market data and, therefore, are classified within Level 2 of the valuation hierarchy. The Company is required to post cash collateral to swap counterparties for interest rate derivative contracts that are in a liability position, thus a credit risk adjustment on interest rate swaps is not warranted.

Cash Value of Life Insurance

Fair value is equal to the cash surrender value of the life insurance policies.

The following table presents the fair value measurements of assets and liabilities recognized in the accompanying consolidated balance sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall at June 30, 2016 and September 30, 2015 (in thousands):

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Following is a description of the valuation methodologies used for assets and liabilities measured at fair value on a nonrecurring basis and recognized in the accompanying consolidated balance sheets, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy.

Impaired Loans (Collateral Dependent)

Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured for impairment. Allowable methods for estimating fair value include using the fair value of the collateral for collateral dependent loans or, where a loan is determined not to be collateral dependent, using the discounted cash flow method.

If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of the impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor, if necessary, to the appraised value and including costs to sell. Because many of these inputs are not observable, the measurements are classified as Level 3.

Other Real Estate Owned (OREO)

Other real estate owned consists of loan collateral that has been repossessed through foreclosure. This collateral is comprised of commercial and residential real estate. OREO is recorded initially at fair value of the collateral less estimated selling costs. Subsequent to foreclosure, valuations are updated periodically, and the assets may be marked down further to fair value less selling costs, reflecting a valuation allowance. Fair value measurements may be based upon appraisals, third-party price opinions, or internally developed pricing methods. These measurements are classified as Level 3.

Mortgage Loans Held for Sale

Fair value of mortgage loans held for sale is based on either quoted prices for the same or similar loans, or values obtained from third parties, or are estimated for portfolios of loans with similar financial characteristics and are therefore considered a Level 2 valuation.

Loan Servicing Rights

Fair value is determined at a tranche level, based on market prices for comparable mortgage servicing contracts (Level 3), when available, or alternatively based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model utilizes interest rate, prepayment speed, and default rate assumptions that market participants would use in estimating future net servicing income and that can be validated against market data (Level 3).

The following tables present the fair value measurement of assets and liabilities measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at June 30, 2016 and September 30, 2015 (in thousands):

	Fair Value		Level 1		Level 2		Level 3
As of June 30, 2016
Other real estate owned	$	3,985	$	—	$	—	$	3,985
Impaired loans	160,151		—		—		160,151
Loans held for sale, at lower of cost or fair value	21,301		—		21,301		—
Loan servicing rights	6,231		—		—		6,231
As of September 30, 2015
Other real estate owned	$	8,826	$	—	$	—	$	8,826
Impaired loans	153,318		—		—		153,318
Loans held for sale, at lower of cost or fair value	9,867		—		9,867		—
Loan servicing rights	—		—		—		—

The valuation techniques and significant unobservable inputs used to measure Level 3 fair value measurements at June 30, 2016 were as follows (in thousands):

Financial Instrument	Fair Value of Assets / (Liabilities) at June 30, 2016		Valuation Technique(s)	Unobservable Input	Range	Weighted Average
Other real estate owned	$	3,985	Appraisal value	Property specific adjustment	N/A	N/A
Impaired loans	160,151		Appraisal value	Property specific adjustment	N/A	N/A
Loan servicing rights	6,231		Discounted cash flows	Constant prepayment rate Discount rate	13.0 - 22.0% 9.5 - 15.0%	16.4% 11.6%

Disclosures about Fair Value of Financial Instruments

For financial instruments that have quoted market prices, those quotes are used to determine fair value. Financial instruments that have no defined maturity, have a remaining maturity of 180 days or less, or reprice frequently to a market rate are assumed to have a fair value that approximates carrying value, after taking into consideration any applicable credit risk. If no market quotes are available, financial instruments are valued by discounting the expected cash flows using an estimated current market interest rate for the financial instrument.

The short maturity of the Company’s assets and liabilities results in having a significant number of financial instruments whose fair value equals or closely approximates carrying value. Such financial instruments are reported in the following consolidated balance sheet categories: cash and due from banks, securities sold under agreements to repurchase, and accrued interest.

Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments include premises and equipment, deferred income taxes, goodwill, and core deposit and other intangibles. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

Off-balance sheet instruments (commitments to extend credit and standby letters of credit) are generally short-term and at variable rates. Therefore, both the carrying amount and the estimated fair value associated with these instruments are immaterial. Fair values for balance sheet instruments as of June 30, 2016 and September 30, 2015, are as follows (in thousands):

		June 30, 2016				September 30, 2015
	Level in Fair Value Hierarchy	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Assets
Cash and due from banks	Level 1	$	475,785	$	475,785	$	237,770	$	237,770
Loans, net excluding fair valued loans and loans held for sale	Level 3	7,364,988		7,337,738		6,139,444		6,120,262

Subordinated debentures and subordinated notes payable	Level 2	111,827		113,083		90,727		91,305

The following methods and assumptions were used in estimating the fair value of financial instruments that were not previously disclosed:

Cash and cash due from banks: Due to the short term nature of cash and cash equivalents, the estimated fair value is equal to the carrying value and they are categorized as a Level 1 fair value measurement.

Loans, net excluding fair valued loans and loans held for sale: The fair value of the loan portfolio is estimated using observable inputs including estimated cash flows, and discount rates based on interest rates currently being offered for loans with similar terms, to borrowers of similar credit quality. Loans held for investment are categorized as a Level 3 fair value measurement.

Accrued interest receivable: Due to the nature of accrued interest receivable, the estimated fair value is equal to the carrying value and they are categorized as a Level 2 fair value measurement.

Federal Home Loan Bank stock: The carrying amount of FHLB stock approximates its fair value as it can only be redeemed with the FHLB at par value. Federal Home Loan Bank stock has been categorized as a Level 2 fair value measurement.

Deposits: The estimated fair value of deposits with no stated maturity, such as non-interest bearing demand deposits, savings, NOW, and money market accounts, is equal to the amount payable on demand. The fair value of interest-bearing time deposits is based on the discounted value of contractual cash flows of such deposits, taking into account the option for early withdrawal. The discount rate is estimated using the rates offered by the Company, at the respective measurement dates, for deposits of similar maturities. Deposits have been categorized as a Level 2 fair value measurement.

FHLB advances and other borrowings: The fair value of FHLB advances and other borrowings is estimated using discounted cash flow analysis, based on current incremental borrowing rates for similar types of borrowing arrangements. In the absence of a reasonably precise methodology to determine the fair value of the credit agreement, carrying value has been used to represent fair value. FHLB advances and other borrowings have been categorized as a Level 2 fair value measurement.

Securities sold under repurchase agreements: The Company’s repurchase agreements are overnight transactions that mature the day after the transaction, and as a result of this short-term nature, the estimated fair value equals the carrying value. Securities sold under repurchase agreements have been categorized as a Level 2 fair value measurement.

Accrued interest payable: Due to the nature of accrued interest payable, the estimated fair value is equal to the carrying value and they are categorized as a Level 2 fair value measurement.

Subordinated Debentures and Subordinated Notes Payable: The fair value of subordinated debentures and subordinated notes payable is estimated using discounted cash flow analysis, based on current incremental debt rates. Subordinated debentures and subordinated notes payable have been categorized as a Level 2 fair value measurement.

Earnings Per Share [Abstract]

Earnings per Share

Earnings per Share

Basic earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period, excluding outstanding non-vested restricted stock awards. Diluted earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding determined for the basic earnings per share calculation plus the dilutive effect of stock compensation using the treasury stock method.

The following information was used in the computation of basic earnings per share (EPS) for the three and nine months ended June 30, 2016 and 2015 (in thousands, except share data):

	Three Months Ended June 30,				Nine Months Ended June 30,

Nature of Operations and Summary of Significant Policies (Policies)

9 Months Ended

Jun. 30, 2016

Accounting Policies [Abstract]

Basis of Presentation

The accompanying unaudited consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and reflect all adjustments that are, in the opinion of management, necessary for the fair presentation of the financial position and results of operations for the periods presented. All such adjustments are of a normal recurring nature.

Certain previously reported amounts have been reclassified to conform to the current presentation.

Principles of Consolidation

The accompanying unaudited consolidated financial statements include the accounts and results of operations of the Company and its subsidiaries after elimination of all significant intercompany accounts and transactions. The preparation of unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates.

Business Combinations

The Company accounts for business combinations under the acquisition method of accounting in accordance with ASC 805, “Business Combinations” (“ASC 805”). The Company recognizes the fair value of the assets acquired and liabilities assumed, immediately expenses transaction costs and accounts for restructuring plans separately from the business combination. There is no separate recognition of the acquired allowance for loan and lease losses on the acquirer’s balance sheet as credit related factors are incorporated directly into the fair value of the loans recorded at the acquisition date. The excess of the cost of the acquisition over the fair value of the net tangible and intangible assets acquired is recorded as goodwill. Alternatively, a bargain purchase gain is recorded equal to the amount by which the fair value of assets purchased exceeds the fair value of liabilities assumed and consideration paid.

Results of operations of the acquired business are included in the consolidated statements of comprehensive income from the effective date of acquisition.

Securities

The Company classifies securities upon purchase in one of three categories: trading, held to maturity, or available for sale. Debt and equity securities held for resale are classified as trading. Debt securities for which the Company has the ability and positive intent to hold until maturity are classified as held to maturity. All other securities are classified as available for sale as they may be sold prior to maturity in response to changes in the Company’s interest rate risk profile, funding needs, demand for collateralized deposits by public entities or other reasons.

Held to maturity securities are stated at amortized cost, which represents actual cost adjusted for premium amortization and discount accretion. Available for sale securities are stated at fair value, with unrealized gains and losses, net of related taxes, included in stockholders’ equity as a component of accumulated other comprehensive income (loss).

Trading securities are stated at fair value. Realized and unrealized gains and losses from sales and fair value adjustments of trading securities are included in other noninterest income in the consolidated statements of comprehensive income.

Purchases and sales of securities are recognized on a trade date basis. The cost of securities sold is based on the specific identification method.

Declines in the fair value of investment securities available for sale (with certain exceptions for debt securities noted below) that are deemed to be other-than-temporary are recognized in earnings as a realized loss, and a new cost basis for the securities is established. In evaluating other-than-temporary impairment, management considers the length of time and extent to which the fair value has been less than amortized cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value in the near term. Declines in the fair value of debt securities below amortized cost are deemed to be other-than-temporary in circumstances where: (1) the Company has the intent to sell a security; (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security. If the Company intends to sell a security or if it is more likely than not that the Company will be required to sell the security before recovery, an other-than-temporary impairment loss is recognized in earnings equal to the difference between the security’s amortized cost basis and its fair value. If the Company does not intend to sell the security or it is not more likely than not that it will be required to sell the security before recovery, the other-than-temporary impairment write-down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in accumulated other comprehensive income (loss).

Interest and dividends, including amortization of premiums and accretion of discounts, are recognized as interest or dividend income when earned. Realized gains and losses on sales (using the specific identification method) and declines in value judged to be other- than-temporary are included in noninterest income in the consolidated statements of comprehensive income.

Loans

The Company’s accounting method for loans differs depending on whether the loans were originated or purchased and, for purchased loans, whether the loans were acquired at a discount related to evidence of credit deterioration since date of origination.

Originated Loans

Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or pay-off, generally are reported at their outstanding principal balance, adjusted for charge-offs, the allowance for loan and lease losses, and any unamortized deferred fees or costs. Other fees, not associated with originating a loan are recognized as fee income when earned.

Interest income on loans is accrued daily on the outstanding balances. Accrual of interest is discontinued when management believes, after considering collection efforts and other factors, the borrower’s financial condition is such that collection of interest is doubtful, which is generally at 90 days past due. Generally, when loans are placed on nonaccrual status, interest receivable is reversed against interest income in the current period. Interest payments received thereafter are applied as a reduction to the remaining principal balance as long as concern exists as to the ultimate collection of the principal. Loans are removed from nonaccrual status when they become current as to both principal and interest and concern no longer exists as to the collectability of principal and interest.

The Company has elected to measure certain long-term loans and written loan commitments at fair value to assist in managing interest rate risk for longer-term loans. Fair value loans are fixed-rate loans having original maturities of 5 years or greater (typically between 5 and 15 years) to our business and agribusiness banking customers to assist them in facilitating their risk management strategies. The fair value option was elected upon the origination or acquisition of these loans and written loan commitments. Interest income is recognized in the same manner on loans reported at fair value as on non-fair value loans, except in regard to origination fees and costs which are recognized immediately upon closing. The changes in fair value of long-term loans and written loan commitments at fair value are reported in noninterest income.

For loans held for sale, loan fees charged or received on origination, net of certain direct loan origination costs, are recognized in income when the related loan is sold. For loans held for investment, loan fees, net of certain direct loan origination costs, are deferred, and the net amount is amortized as an adjustment of the related loan’s yield. The Company is generally amortizing these amounts over the contractual lives of the loans. Commitment fees are recognized as income when received.

The Company grants commercial, agricultural, consumer, residential real estate, and other loans to customers primarily in Arizona, Colorado, Iowa, Kansas, Missouri, Minnesota, Nebraska, North Dakota and South Dakota. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the borrower. Collateral held varies but includes accounts receivable, inventory, property and equipment, residential real estate, and income-producing commercial and agricultural properties. Government guarantees are also obtained for some loans, which reduces the Company’s risk of loss.

Loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value. Loans held for sale include fixed rate single-family residential mortgage loans under contract to be sold in the secondary market. In most cases, loans are carried at cost and sold within 45 days. These loans are sold with the mortgage servicing rights released. Under limited circumstances, buyers may have recourse to return a purchased loan to the Company. Recourse conditions may include early payment default, breach of representation or warranties, or documentation deficiencies.

Fair value of loans held for sale is determined based on prevailing market prices for loans with similar characteristics, sale contract prices, or, for certain portfolios, discounted cash flow analysis. Declines in fair value below cost (and subsequent recoveries) are recognized in net gain on sale of loans. Deferred fees and costs related to these loans are not amortized but are recognized as part of the cost basis of the loan at the time it is sold. Gains or losses on sales are recognized upon delivery and included in net gain on sale of loans.

Purchased Loans

Loans acquired (non-impaired and impaired) in a business acquisition are recorded at their fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date.

In determining the acquisition date fair value of purchased loans with evidence of credit deterioration (“ASC 310-30 loans”), and in subsequent accounting, the Company generally aggregates impaired purchased consumer and certain smaller balance impaired commercial loans into pools of loans with common risk characteristics, while accounting for larger-balance impaired commercial loans individually. Expected cash flows at the acquisition date in excess of the fair value of loans are recorded as interest income over the life of the loans using a level-yield method.

Management estimates the cash flows expected to be collected at acquisition and at subsequent measurement dates using internal risk models, which incorporate the estimate of key assumptions, such as default rates, loss severity, and prepayment speeds. Subsequent to the acquisition date, decreases in cash flows over those expected at the acquisition date are recognized by recording an allowance for loan and lease losses. Subsequent increases in cash flow over those expected at the acquisition date are recognized as reductions to allowance for loan and lease losses to the extent impairment was previously recognized and thereafter as interest income prospectively.

For purchased loans not deemed impaired at the acquisition date, the difference between the fair value and the unpaid principal balance of the loan at acquisition date is amortized or accreted to interest income using the effective interest method over the remaining period to contractual maturity.

Credit Risk Management

The Company’s strategy for credit risk management includes well-defined, centralized credit policies, uniform underwriting criteria and ongoing risk monitoring and review processes for all credit exposures. The strategy also emphasizes diversification on a geographic, industry, and customer level; regular credit examinations; and management reviews of loans exhibiting deterioration of credit quality. The credit risk management strategy also includes a credit risk assessment process that performs assessments of compliance with commercial and consumer credit policies, risk ratings, and other critical credit information. Loan decisions are documented with respect to the borrower’s business, purpose of the loan, evaluation of the repayment sources, and the associated risks, evaluation of collateral, covenants and monitoring requirements, and risk rating rationale.

The Company categorizes its loan portfolio into six classes, which is the level at which it develops and documents a systematic methodology to determine the allowance for loan and lease losses. The Company’s six loan portfolio classes are residential real estate, commercial real estate, commercial non real estate, agriculture, consumer and other lending.

The residential real estate lending class includes loans made to consumer customers including residential mortgages, residential construction loans and home equity loans and lines. These loans are typically fixed rate loans secured by residential real estate. Home equity lines are revolving accounts giving the borrower the ability to draw and repay balances repeatedly, up to a maximum commitment, and are secured by residential real estate. Home equity lines typically have variable rate terms which are benchmarked to a prime rate. Historical loss history is the primary factor in determining the allowance for loan and lease losses for the residential real estate lending class. Key risk characteristics relevant to residential real estate lending class loans primarily relate to the borrower’s capacity and willingness to repay and include unemployment rates and other economic factors, and customer payment history. These risk characteristics, among others, are reflected in the environmental factors considered in determining the allowance for loan and lease losses.

The commercial real estate lending class includes loans made to small and middle market businesses, including multifamily properties. Loans in this class are secured by commercial real estate. Historical loss history and updated loan-to-value information on collateral-dependent loans are the primary factors in determining the allowance for loan and lease losses for the commercial real estate lending class. Key risk characteristics relevant to the commercial real estate lending class include the industry and geography of the borrower’s business, purpose of the loan, repayment sources, borrower’s debt capacity and financial performance, loan covenants, and nature of pledged collateral. We consider these risk characteristics in assigning risk ratings and estimating environmental factors considered in determining the allowance for loan and lease losses.

The commercial non real estate lending class includes loans made to small and middle market businesses, and loans made to public sector customers. Loans in this class are generally secured by business assets and guaranteed by owners; cashflows are most often our primary source of repayment. Historical loss history and updated loan-to-value information on collateral-dependent loans are the primary factors in determining the allowance for loan and lease losses for the commercial non real estate lending class. Key risk characteristics relevant to the commercial non real estate lending class include the industry and geography of the borrower’s business, purpose of the loan, repayment sources, borrower’s debt capacity and financial performance, loan covenants, and nature of pledged collateral. We consider these risk characteristics in assigning risk ratings and estimating environmental factors considered in determining the allowance for loan and lease losses.

The agriculture lending class includes loans made to small and mid-size agricultural businesses and individuals. Loans in this class are generally secured by operating assets and guaranteed by owners; cashflows are most often our primary source of repayment. Historical loss history and updated loan-to-value information on collateral-dependent loans are the primary factors in determining the allowance for loan and lease losses for the agriculture lending class. Key risk characteristics relevant to the agriculture lending class include the geography of the borrower’s operations, commodity prices and weather patterns, purpose of the loan, repayment sources, borrower’s debt capacity and financial performance, loan covenants, and nature of pledged collateral. We consider these risk characteristics in assigning risk ratings and estimating environmental factors considered in determining the allowance for loan and lease losses.

The consumer lending class includes loans made to consumer customers including loans secured by automobiles and other installment loans, and the other lending class includes credit card loans and unsecured revolving credit lines. Historical loss history is the primary factor in determining the allowance for loan and lease losses for the consumer and other lending classes. Key risk characteristics relevant to loans in the consumer and other lending classes primarily relate to the borrower’s capacity and willingness to repay and include unemployment rates and other economic factors, and customer payment and overall credit history. These risk characteristics, among others, are reflected in the environmental factors considered in determining the allowance for loan and lease losses.

The Company assigns all non-consumer loans a credit quality risk rating. These ratings are Pass, Watch, Substandard, Doubtful, and Loss. Loans with a Pass and Watch rating represent those loans not classified on the Company’s rating scale for problem credits, with loans with a Watch rating being monitored and updated at least quarterly by management. Substandard loans are those where a well-defined weakness has been identified that may put full collection of contractual debt at risk. Doubtful loans are those where a well-defined weakness has been identified and a loss of contractual debt is probable. Substandard and doubtful loans are monitored and updated monthly. All loan risk ratings are updated and monitored on a continuous basis. The Company generally does not risk rate consumer loans unless a default event such as bankruptcy or extended nonperformance takes place. Alternatively, standard credit scoring systems are used to assess credit risks of consumer loans.

Troubled Debt Restructurings (“TDRs”)

Loans modified under troubled debt restructurings involve granting a concession to a borrower who is experiencing financial difficulty. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance, or other actions intended to maximize collection, which generally would not otherwise be considered. Our TDRs include performing and nonperforming TDRs, which consist of loans that continue to accrue interest at the loan's original interest rate as we expect to collect the remaining principal and interest on the loan, and nonaccrual TDRs, which include loans that are in a nonaccrual status and are no longer accruing interest, as we do not expect to collect the full amount of principal and interest owned from the borrower on these loans. At the time of modification (except for loans on nonaccrual status), a TDR is classified as nonperforming TDR until a six-month payment history of principal and interest payments, in accordance with the terms of the loan modification, is sustained, at which time we move the loan to a performing status (performing TDR). If we do not expect to collect all principal and interest on the loan, the modified loan is classified as a nonaccrual TDR. All TDRs are accounted for as impaired loans and are included in our analysis of the allowance for loan and lease losses. A TDR that has been re-underwritten and renewed for a borrower who is no longer experiencing financial difficulty and which yields a market rate of interest at the time of a renewal is no longer considered a TDR.

Allowance for Loan and Lease Losses (“ALLL”) and Unfunded Commitments

The Company maintains an allowance for loan and lease losses at a level management believes is appropriate to reserve for credit losses inherent in our loan portfolio. The allowance for loan and lease losses is determined based on an ongoing evaluation, driven primarily by monitoring changes in loan risk grades, delinquencies, and other credit risk indicators, which is inherently subjective.

The Company considers the uncertainty related to certain industry sectors and the extent of credit exposure to specific borrowers within the portfolio. In addition, consideration is given to concentration risks associated with the various loan portfolios and current economic conditions that might impact the portfolio. The Company also considers changes, if any, in underwriting activities, the loan portfolio composition (including product mix and geographic, industry, or customer-specific concentrations), trends in loan performance, the level of allowance coverage relative to similar banking institutions and macroeconomic factors, such as changes in unemployment rates, gross domestic product, and consumer bankruptcy filings.

All of these estimates are susceptible to significant change. Changes to the allowance for loan and lease losses are made by charges to the provision for loan and lease losses, which is reflected in the consolidated statements of comprehensive income. Past due status is monitored as an indicator of credit deterioration. Loans that are 90 days or more past due are put on nonaccrual status unless the loan is well secured and in the process of collection. Loans deemed to be uncollectible are charged off against the allowance for loan and lease losses. Recoveries of amounts previously charged-off are credited to the allowance for loan and lease losses.

The allowance for loan and lease losses consist of reserves for probable losses that have been identified related to specific borrowing relationships that are individually evaluated for impairment (“specific reserve”), as well as probable losses inherent in our loan portfolio that are not specifically identified (“collective reserve”).

The specific reserve relates to impaired loans. A loan is impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due (interest as well as principal) according to the contractual terms of the loan agreement. Specific reserves are determined on a loan-by-loan basis based on management’s best estimate of the Company’s exposure, given the current payment status of the loan, the present value of expected payments, and the value of any underlying collateral. Impaired loans also include loans modified in troubled debt restructurings. Generally, the impairment related to troubled debt restructurings is measured based on the fair value of the collateral, less cost to sell, or the present value of expected payments relative to the unpaid principal balance. If the impaired loan is identified as collateral dependent, then the fair value of the collateral method of measuring the amount of the impairment is utilized. This method requires obtaining an independent appraisal of the collateral and applying a discount factor to the appraised value, if necessary, and including costs to sell.

Management’s estimate for collective reserves reflects losses incurred in the loan portfolio as of the consolidated balance sheet reporting date. Incurred loss estimates primarily are based on historical loss experience and portfolio mix. Incurred loss estimates may be adjusted for qualitative factors such as current economic conditions and current portfolio trends including credit quality, concentrations, aging of the portfolio, and/or significant policy and underwriting changes.

The Company maintains an ALLL for acquired impaired loans accounted for under ASC 310-30, resulting from decreases in expected cash flows arising from the periodic revaluation of these loans. Any decrease in expected cash flows in the individual loan pool is generally recognized in the current provision for loan and lease losses. Any increase in expected cash flows is generally not recognized immediately, but is instead reflected as an adjustment to the related loan or pool's yield on a prospective basis once any previously recorded provision for loan and lease loss has been recognized.

For acquired nonimpaired loans accounted for under ASC 310-20, the Company utilizes methods to estimate the required allowance for loan and lease losses similar to originated loans; the required reserve is compared to the net carrying value of each acquired nonimpaired loan (by segment) to determine if a provision is required.

While management uses the best information available to establish the allowance for loan and lease losses, future adjustments may be necessary if economic conditions differ substantially from the assumptions used in performing the estimates.

Unfunded residential mortgage loan commitments entered into in connection with mortgage loans to be held for sale are considered derivatives and are recorded at fair value and included in other liabilities on the consolidated balance sheets with changes in fair value recorded in other interest income. All other unfunded loan commitments are generally related to providing credit facilities to customers and are not considered derivatives. For purchased loans, the fair value of the unfunded credit commitments is considered in determination of the fair value of the loans recorded at the date of acquisition. Reserves for credit exposure on all other unfunded credit commitments are recorded in other liabilities on the consolidated balance sheets.

FDIC Indemnification Asset and Clawback Liability

In conjunction with a Federal Deposit Insurance Corporation (“FDIC”)-assisted transaction of TierOne Bank in 2010, the Company entered into two loss share agreements with the FDIC, one covering certain single family residential mortgage loans with the claim period ending June 2020 and one covering commercial loans and other assets, in which the claim period ended in June 2015. The agreements cover a portion of realized losses on loans, foreclosed real estate and certain other assets. The Company has recorded assets on the consolidated balance sheets (i.e. indemnification assets) representing estimated future amounts recoverable from the FDIC.

Fair values of loans covered by the loss sharing agreements at the acquisition date were estimated based on projected cash flows available based on the expected probability of default, default timing and loss given default, the expected reimbursement rates (generally 80%) from the FDIC and other relevant terms of the loss sharing agreements. The initial fair value was established by discounting these expected cash flows with a market discount rate for instruments with like maturity and risk characteristics.

The loss share assets are measured separately from the related loans and foreclosed real estate and recorded as an FDIC indemnification asset on the consolidated balance sheets because they are not contractually embedded in the loans and are not transferable with the loans should the Company choose to dispose of them. Subsequent to the acquisition date, reimbursements received from the FDIC for actual incurred losses reduce the carrying amount of the loss share assets. Reductions to expected losses on covered assets, to the extent such reductions to expected losses are the result of an improvement to the actual or expected cash flows from the covered assets, also reduce the carrying amount of the loss share assets. The rate of accretion of the indemnification asset discount included in interest income slows to mirror the accelerated accretion of the loan discount. Additional expected losses on covered assets, to the extent such expected losses result in the recognition of an allowance for loan and lease losses, increase the carrying amount of the loss share assets. A related increase in the value of the indemnification asset up to the amount covered by the FDIC is calculated based on the reimbursement rates from the FDIC and is included in other noninterest income. The corresponding loan accretion or amortization is recorded as a component of interest income on the consolidated statements of comprehensive income. Although these assets are contractual receivables from the FDIC, there are no contractual interest rates.

As part of the loss sharing agreements, the Company also assumed a liability (“FDIC Clawback Liability”) to be paid within 45 days subsequent to the maturity or termination of the loss sharing agreements that is contingent upon actual losses incurred over the life of the agreements relative to expected losses considered in the consideration paid at acquisition date and the amount of losses reimbursed to the Company under the loss sharing agreements. The liability was recorded at fair value as of the acquisition date. The fair value was based on a discounted cash flow calculation that considered the formula defined in the loss sharing agreements and projected losses. The difference between the fair value at acquisition date and the projected losses is amortized through other noninterest expense. As projected losses and reimbursements are updated, as described above, the FDIC Clawback Liability is adjusted and a gain or loss is recorded in other noninterest expense.

Loan Servicing Rights

The Company records a servicing asset for contractually separated servicing from the underlying mortgage loans. Fair value is based on market prices for comparable mortgage servicing contracts, when available or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The asset is amortized into mortgage banking income, net on the consolidated statement of comprehensive income in proportion to and over the period of estimated net servicing income.

Loan servicing rights are evaluated for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is determined by stratifying rights into groupings based on characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists, a reduction of the allowance may be recorded as an increase to noninterest income. If the Company determines the impairment to be permanent, the valuation is written off against the loan servicing rights, which results in a new amortized balance. Changes in the valuation allowance are reported in mortgage banking income, net in the consolidated statement of comprehensive income. The fair value of loan servicing rights is subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Estimating future cash flows on the underlying mortgages is a difficult analysis and requires judgment based on the best information available. Based on the Company's analysis of loan servicing rights, a valuation allowance of $0.2 million was recorded at June 30, 2016.

Servicing fee income, which is reported in noninterest income, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding balance or a fixed amount per loan and are recorded as income as earned. The amortization of loan servicing rights is netted against mortgage banking income, net in the statement of consolidated comprehensive income.

Goodwill

Goodwill represents the cost in excess of the fair value of net assets acquired (including identifiable intangibles) in transactions accounted for as business acquisitions. Goodwill is evaluated annually for impairment or more frequently if events and circumstances exist that indicates that a goodwill impairment test should be performed. The Company performs its impairment evaluation as of June 30 of each fiscal year. If the implied fair value of goodwill is lower than its carrying amount, goodwill impairment is indicated and goodwill is written down to its implied fair value. Subsequent increases in goodwill are not recognized in the consolidated financial statements.

Core Deposits and Other Intangibles

Intangible assets consist of core deposits, brand intangible, customer relationships, and other intangibles. Core deposits represent the identifiable intangible value assigned to core deposit bases arising from purchase acquisitions. Brand intangible represents the value associated with the Bank charter. Customer relationships intangible represents the identifiable intangible value assigned to customer relationships arising from a purchase acquisition. Other intangibles represent contractual franchise arrangements under which the franchiser grants the franchisee the right to perform certain functions within a designated geographical area. The methods and lives used to amortize intangible assets are as follows:

Intangible	Method	Years
Core deposit	Straight-line or effective yield	5 - 10
Brand intangible	Straight-line	15
Customer relationships	Straight-line	8.5
Other intangibles	Straight-line	1.25 - 9.33

Intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

Derivatives

The Company maintains an overall interest rate risk management strategy that permits the use of derivative instruments to modify exposure to interest rate risk. The Company enters into interest rate swap contracts to offset the interest rate risk associated with borrowers who lock in long-term fixed rates (greater than or equal to 5 years to maturity) through a fixed rate loan. These contracts do not qualify for hedge accounting. Generally, under these swaps, the Company agrees with various swap counterparties to exchange the difference between fixed-rate and floating-rate interest amounts based upon notional principal amounts. These interest rate derivative instruments are recognized as assets and liabilities on the consolidated balance sheets and measured at fair value, with changes in fair value reported in net realized and unrealized gain (loss) on derivatives. Since each fixed rate loan is paired with an offsetting derivative contract, the impact to net income is minimized.

The Company enters into forward interest rate lock commitments on mortgage loans to be held for sale, which are commitments to originate loans whereby the interest rate on the loan is determined prior to funding. The Company also has corresponding forward sales contracts related to these interest rate lock commitments. Both the mortgage loan commitments and the related sales contracts are considered derivatives and are recorded at fair value with changes in fair value recorded in noninterest income.

Stock Based Compensation

Restricted and performance-based stock units/awards are classified as equity awards and accounted for under the Treasury method. Compensation expense for non-vested stock units/awards is based on the fair value of the award on the measurement date, which, for the Company, is the date of the grant and is recognized ratably over the vesting or performance period of the award. The fair value of non-vested stock units/awards is generally the market price of the Company's stock on the date of grant.

Income Taxes

The Company was required to file a consolidated income tax return with National Americas Investment, Inc. ("NAI") (a wholly owned indirect subsidiary of NAB) until NAI's dissolution on October 17, 2014. Income taxes are allocated pursuant to a tax-sharing arrangement, whereby the Company will pay federal and state income taxes as if it were filing on a stand-alone basis. Income tax expense includes two components: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over income. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods.

Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.

Tax benefits related to uncertain tax positions are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term "more likely than not" means a likelihood of more than 50 percent; the terms "examined" and "upon examination" also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information.

The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment.

Transfers of Financial Assets

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company-put presumptively beyond reach of the Company and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.

Securities sold under agreements to repurchase are accounted for as collateralized financing transactions and are recorded at amounts at which the securities were financed, plus accrued interest.

Defined Benefit Plan

The Company assumed plan sponsorship of the HF Financial Corp. Pension Plan during the quarter as part of the HF Financial acquisition. Defined benefit pension obligation and related costs are calculated using actuarial concepts and measurements. Three critical assumptions, the discount rate, the expected long-term rate of return on plan assets, and mortality rates are important elements of expense and/or benefit obligation measurements. Other assumptions involve employee demographic factors such as retirement patterns and turnover. The Company evaluates all assumptions annually. For accounting purposes, mortality assumptions at June 30, 2016 were based on the RP-2014 mortality tables and the MP 2015 projection scales.

The discount rate enables the Company to state expected future benefit payments as a present value on the measurement date. The Company determined the discount rate at June 30, 2016 by utilizing the standard duration index from the Citi Pension Discount Curve and Liability Index. A lower discount rate increases the present value of benefit obligations and increases pension expense.

To determine expected long-term rate of return on defined benefit pension plan assets, the Company considers the current asset allocation of the defined benefit pension plan, as well as historical and expected returns on each asset class. A lower expected rate of return on defined pension plan assets will increase pension expense.

The Company recognizes the over- or under-funded status of a plan as an other asset or other liability in the consolidated balance sheet as measured by the difference between the fair value of the plan assets and the projected benefit obligation. When recorded, unrecognized prior service costs and actuarial gains and losses are recognized as a component of accumulated other comprehensive income (loss).

Revenue Recognition

The Company recognizes revenue as it is earned based on contractual terms, as transactions occur, or as services are provided and collectability is reasonably assured. Certain specific policies related to service charges and other fees include the following:

Deposit Service Charges

Service charges on deposit accounts are primarily fees related to customer overdraft events and not sufficient funds fees, net of any refunded fees, and are recognized as transactions occur and services are provided. Service charges on deposit accounts also relate to monthly fees based on minimum balances, and are earned as transactions occur and services are provided.

Interchange Fees

Interchange fees include interchange income from consumer debit card transactions processed through card association networks. Interchange income is a fee paid by a merchant bank to the card-issuing bank through the interchange network. Interchange fees are set by the card association networks and are based on cardholder purchase volumes.

Wealth Management Fees

Wealth management fees include commission income from financial planning, investment management and insurance operations.

Comprehensive Income

Comprehensive income consists of net income and other comprehensive income, net of applicable income taxes. Other comprehensive income (loss) consists entirely of unrealized appreciation (depreciation) on available-for-sale securities.

Subsequent Events

The Company has evaluated all events or transactions that occurred through the date the Company issued these financial statements. During this period, the Company did not have any material recognizable or non-recognizable subsequent events other than outlined below.

New Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which addresses timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires institutions to measure all expected credit losses related to financial assets measured at amortized costs with an expected loss model based on historical experience, current conditions and reasonable and supportable forecasts relevant to affect the collectibility of the financial assets, which is referred to as the current expected credit loss (CECL) model. The ASU requires enhanced disclosures, including qualitative and quantitative requirements, to help understand significant estimates and judgments used in estimating credit losses, as well as provide additional information about the amounts recorded in the financial statements. ASU 2016-13 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted after December 15, 2018. The amendment requires the use of the modified retrospective approach for adoption. The Company is currently evaluating the potential impact of ASU 2016-13 on our financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Based Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which addresses 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. ASU 2016-09 is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Earlier application is permitted. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The Company is currently evaluating the potential impact of ASU 2016-09 on our financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires that lessees recognize the assets and liabilities arising from leases on the balance sheet. ASU 2015-16 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the potential impact of ASU 2016-02 on our financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities, which addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the potential impact of ASU 2016-01 on our financial statements.

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805) - Simplifying the Accounting for Measurement-Period Adjustments, which requires that adjustments to provisional amounts that are identified during the measurement period of a business combination be recognized in the reporting period in which the adjustment amounts are determined. Furthermore, the income statement effects of such adjustments, if any, must be calculated as if the accounting had been completed at the acquisition date. The portion of the amount recorded in current-period earnings that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. Under previous guidance, adjustments to provisional amounts identified during the measurement period are to be recognized retrospectively. ASU 2015-16 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Earlier application is permitted for financial statements that have not been issued, therefore the Company has elected to early adopt this ASU as of and for its quarter ended June 30, 2016. The adoption of ASU 2015-16 in the third quarter of 2016 did not have a material impact on the Company's consolidated balance sheet or consolidated statement of comprehensive income. See also Note 3 to these consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which implements a common revenue standard that clarifies the principles for recognizing revenue. 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 and services. In August 2015, the FASB issued ASU No. 2015-14 which deferred the effective date of ASU No. 2014-09 to annual reporting periods beginning after December 15, 2017. In March 2016, the FASB issued ASU No. 2016-08, which intends to improve the operability and understandability of the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU No. 2016-10, which clarifies guidance pertaining to the identification of performance obligations and the licensing implementation. In May 2016, the FASB issued ASU Nos. 2016-11 and 2016-12, which further clarify guidance and provide practical expedients related to the adoption of ASU No. 2014-09. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is currently evaluating the potential impact of these standards on our financial statements.
