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 “anticipates,” “believes,” “can,” “could,” “may,” “predicts,” “potential,” “should,” “will,” “estimate,” “plans,” “projects,” “continuing,” “ongoing,” “expects,” "views," “intends” and similar words or phrases. 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.

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;


•	our ability to anticipate interest rate changes and manage interest rate risk;


•	our ability to achieve loan and deposit growth;


•	the relative strength or weakness of the commercial, agricultural and real estate markets where our borrowers are located, including without limitation related asset and market prices;


•	declines in asset prices and the market prices for agricultural products or changes in governmental support programs for the agricultural sector;


•	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 develop and effectively use the quantitative models we rely upon in our business;


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


•	operational risks or risk management failures by us or critical third parties, including without limitation with respect to data processing, information systems, cyber-security, technological changes, vendor problems, business interruption and fraud risks;


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


•	unanticipated changes in our liquidity position, including but not limited to changes in 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;


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


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


•	the impact of, and changes in applicable laws, regulations and accounting standards, policies and interpretations, including the impact of the Tax Cuts and Jobs Act of 2017;


•	legal, compliance and reputational risks, including litigation and regulatory risks;


•	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;


•	expected cost savings in connection with the consolidation of recent acquisitions may not be fully realized or realized within the expected time frames, and deposit attrition, customer loss and revenue loss following completed acquisitions may be greater than expected;


•	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; 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, 2017.

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, 2017. 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 to reflect events or circumstances occurring after the date on which the statement is made or to reflect the occurrence of unanticipated events.

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 and is listed on the New York Stock Exchange ("NYSE") under the symbol GWB. 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 agri-business 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, 2017, 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 on the consolidated financial statements and accompanying notes. Actual results could differ from these estimates.

FDIC Indemnification Asset and Clawback Liability

FDIC Indemnification assets are included in other assets on the consolidated balance sheets.

Core Deposits and Other Intangibles

Core deposits and other intangibles are included in other assets in the consolidated balance sheets.

Loan Servicing Rights

Loan servicing rights are included in other assets in the consolidated balance sheets.

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. 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 contracts do not qualify for hedge accounting. These interest rate derivative instruments are recognized as other assets or other 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 on the consolidated statements of income. Since each fixed rate loan is paired with an offsetting derivative contract, the impact to net income is minimized. The Company also has back-to-back swaps with loan customers where the Company enters into an interest rate swap with loan customers to provide a facility to mitigate the interest rate risk associated with offering a fixed rate and simultaneously enters into a swap with an outside third party that is matched in exact offsetting terms. The back-to-back swaps are recorded at fair value and recognized as other assets or other liabilities, depending on the rights or obligations under the contract, on the consolidated balance sheet, with changes in fair value reported in net realized and unrealized gain (loss) on derivatives on the consolidated statements of income.

GREAT WESTERN BANCORP, INC.

Notes to Consolidated Financial Statements (Unaudited)

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 and included in other assets or other liabilities on the consolidated balance sheets with changes in fair value offsetting each other in net realized and unrealized gain (loss) on derivatives on the consolidated statements of income.

Subsequent Events

The Company has evaluated all events or transactions that occurred through the date the Company issued these financial statements. Other than those events described below, there were no other material events that would require recognition in the consolidated financial statements or disclosure in the notes to the consolidated financial statements.

On January 25, 2018, the Board of Directors of the Company declared a dividend of $0.20 per common share payable on February 21, 2018 to stockholders of record as of close of business on February 9, 2018.

Correction of Prior Period Balances

The consolidated statements of income for the quarter ended December 31, 2016 has been revised to correct an immaterial classification error in interest income and noninterest income related to credit card interchange income. As a result, the consolidated statements of income has been revised to reflect these changes, as follows:



	As originally reported		Adjustments			As revised
	(dollars in thousands)
Three months ended December 31, 2016
Interest income - loans	$	101,683	$	(1,751	)	$	99,932
Noninterest income - service charges and other fees	12,086		1,751			13,837

Twelve months ended September 30, 2017
Interest income - loans	$	414,434	$	(7,152	)	$	407,282
Noninterest income - service charges and other fees	48,573		7,152			55,725

Twelve months ended September 30, 2016

Noninterest income - service charges and other fees	46,209		6,716			52,925

In August 2017, the Financial Accounting Standards Board ("FASB") issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which amends the hedge accounting recognition and presentation requirements in ASC 815 to improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities to better align the entity’s financial reporting for hedging relationships with those risk management activities and to reduce the complexity of and simplify the application of hedge accounting. ASU 2017-12 is to be applied to all existing hedging relationships on the date of adoption and will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted in any interim period, with the effect of adoption reflected as of the beginning of the fiscal year of adoption. The Company is currently evaluating the potential impact of ASU 2017-12 on our consolidated financial statements.

In March 2017, FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities, which shortens the amortization period for certain callable debt securities held at a premium to the earliest call date unless applicable guidance related to certain pools of securities is applied to consider estimated prepayments. Under prior guidance, entities were generally required to amortize premiums on individual, non-pooled callable debt securities as a yield adjustment over the contractual life of the security. There is no accounting change for debt securities held at a discount. ASU 2017-08 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15,

2018, with early adoption permitted. The Company early adopted ASU 2017-08 during the first quarter of fiscal year 2018. There was no cumulative effect adjustment necessary to the Company's consolidated financial statements.

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 collectability 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 has formed a project team to work on the implementation of ASU 2016-13 and is currently evaluating the potential impact on our consolidated 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 and disclosing key information about leasing arrangements. Lessees will be required to recognize an obligation for future lease payments measured on a discounted basis and a related right-of-use asset. ASU 2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, "Revenue from Contracts with Customers." ASU 2016-02 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 consolidated 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 requires equity investments, in general, to be measured at fair value with changes in fair value recognized in earnings. It also eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost, requires entities to use the exit price notion when measuring fair value, requires an entity to present separately in other comprehensive income the portion of the total change in fair value of a liability resulting from a change in the measurement category and form on the balance sheet or accompanying notes, clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity's other deferred tax assets, and simplifies the impairment assessment of equity investments without readily determinable fair values. 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 does not believe ASU 2016-01 will have a material impact on our consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which implements a more robust framework that clarifies the principles for recognizing revenue and gives greater consistency and comparability in revenue recognition practices. In the new framework, an entity recognizes revenue in an amount that reflects the consideration to which the entity expects to be entitled in exchange for goods or services. The new model requires the identification of performance obligations included in the contract with customers, a determination of the transaction price and an allocation of the price to those performance obligations. The entity recognizes revenue when performance obligations are satisfied. 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 standard, along with subsequent guidance from FASB, lists several items that are specifically out of scope for ASU 2014-09, including but not limited to: core interest income, derivative instruments, investments, and loan origination fees.

To address the new standard, the Company formed a working group and has completed the initial scoping phase to determine which revenue streams may be subject to accounting or disclosure changes upon adoption in October of 2018. Based on this preliminary analysis, we do not anticipate significant changes as a result of implementing the standard, but will conclude on the quantitative and qualitative impacts once we have completed our review of key contracts for any in-scope items over the coming months.

Securities with an estimated fair value of approximately $990.6 million and $951.4 million at December 31, 2017 and September 30, 2017, 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 90% and 68% of the Company’s investment portfolio at estimated fair value at December 31, 2017 and September 30, 2017, 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 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 December 31, 2017 or September 30, 2017.

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:

The loan segments above include loans covered by FDIC loss sharing agreements totaling $53.4 million and $57.5 million as of December 31, 2017 and September 30, 2017, respectively, residential real estate loans held for sale totaling $5.8 million and $7.5 million at December 31, 2017 and September 30, 2017, respectively, and $980.1 million and $1.02 billion of loans accounted for at fair value at December 31, 2017 and September 30, 2017, respectively.

Unearned net deferred fees and costs totaled $11.9 million and $11.6 million as of December 31, 2017 and September 30, 2017, respectively.

Loans in process represent loans that have been funded as of the balance sheet dates but not classified into a loan category and loan payments received as of the balance sheet dates that have not been applied to individual loan accounts. Loans in process totaled $(1.9) million and $(0.8) million at December 31, 2017 and September 30, 2017, respectively.

Loans guaranteed by agencies of the U.S. government totaled $162.3 million and $168.3 million at December 31, 2017 and September 30, 2017, respectively.

Principal balances of residential real estate loans sold totaled $50.2 million and $91.7 million for the three months ended December 31, 2017 and 2016, respectively.

Nonaccrual

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 following table presents the Company’s nonaccrual loans at December 31, 2017 and September 30, 2017, excluding ASC 310-30 loans. Loans greater than 90 days past due and still accruing interest as of December 31, 2017 and September 30, 2017, were $0.2 million and $1.9 million, respectively.

Credit Quality Information

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.

Valuation adjustments made to repossessed properties totaled $0.0 million and $0.4 million for the three months ended December 31, 2017 and 2016, respectively. 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 $6.9 million and $8.8 million at December 31, 2017 and September 30, 2017, respectively. There were no commitments to lend additional funds to borrowers whose loans were modified in a TDR as of December 31, 2017 and September 30, 2017.

The following table presents the recorded value of the Company’s TDR balances as of December 31, 2017 and September 30, 2017:

The table below represents loans that were modified as TDRs within the previous 12 months and for which there was a payment default for the three months ended December 31, 2017 and 2016, respectively.



	Three Months Ended December 31, 2017			Three Months Ended December 31, 2016

A loan is considered to be in payment default once it is 90 days or more contractually past due under the modified terms. The table above includes loans that experienced a payment default during the period, but may be performing in accordance with the modified terms as of the balance sheet date. For the three months ended December 31, 2017 and 2016, there were $0.6 million and $0.0 million, respectively, of loans removed from TDR status as they were restructured at market terms and are performing.

5. Allowance for Loan and Lease Losses

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.

Changes to the allowance for loan and lease losses are made by charges to the provision for loan and lease losses, which is reflected on the consolidated statements of 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 a repayment is eminent. 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 reducing the appraised value by 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.

For acquired loans not accounted for under ASC 310-30 (purchased non-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 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 $0.9 million at December 31, 2017, compared to $1.0 million at September 30, 2017. For the three months ended December 31, 2017, loan pools accounted for under ASC 310-30 had a net reversal of provision of $0.1 million as a result of increases in expected cash flows. For the three months ended December 31, 2016, loan pools accounted for under ASC 310-30 had a net provision of $0.1 million as a result of actual cash flows being lower than expected cash flows.

The reserve for unfunded loan commitments was $0.5 million at both December 31, 2017 and September 30, 2017 and is recorded in other liabilities on the consolidated balance sheets.

6. 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 or Purchase Credit Impaired loans). 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"). Further, these purchased credit impaired loans had differences between contractual amounts owed and cash flows expected to be collected, that were at least in part, due to credit quality. 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 months ended December 31, 2017 and 2016:



	Three Months Ended
	December 31, 2017			December 31, 2016

7. 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 other repossessed property, 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 months ended December 31, 2017 and 2016:



	Three Months Ended

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 commercial loss share agreement claim period ended on June 4, 2015. The non-commercial loss share agreement ends June 4, 2020.

Netting of Derivatives

We record the derivatives on a net basis when a right of offset exists, based on transactions with a single counterparty that are subject to a legally enforceable master netting agreement. When bilateral netting agreements or similar agreements exist between the Company and its counterparties that create a single legal claim or obligation to pay or receive the net amount in settlement of the individual derivative contracts, the Company reports derivative assets and liabilities on a net by derivative contract by counterparty basis. The following tables provide information on the Company's netting adjustments as of December 31, 2017 and September 30, 2017:



	Amounts offset on the Consolidated Balance Sheet

Notes to Consolidated Financial Statements (Unaudited)

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.

Credit-risk-related contingent features

The Company has agreements with its derivative counterparties that contain a provision where if the Company or the derivative counterparty fails to maintain its status as a well/adequately capitalized institution, then the other party has the right to terminate the derivative positions and the Company or the derivative counterparty would be required to settle its obligations under the agreements. The Company has minimum collateral posting thresholds with its derivative counterparties.

As of December 31, 2017 and September 30, 2017, the termination value of derivatives in a net liability position related to these agreements was $10.7 million and $20.3 million, respectively, which includes accrued interest but excludes any adjustment for nonperformance risk. Additionally, as of December 31, 2017 and September 30, 2017 the termination value of derivatives in a net asset position related to these agreements was $1.6 million and $1.2 million, respectively, which includes accrued interest but excludes any adjustment for nonperformance risk and as of December 31, 2017 and September 30, 2017, the derivative counterparty had posted to the Company $1.7 million and $1.0 million, respectively, in eligible collateral.

The effect of derivatives on the consolidated statements of comprehensive income for the three months ended December 31, 2017 and 2016 was as follows:



		Amount of Gain (Loss) Recognized in Statements of Income
		Three Months Ended
	Location of Gain (Loss) Recognized in Statements of Income	December 31, 2017			December 31, 2016
		(dollars in thousands)
Derivatives not designated as hedging instruments:
Interest rate swaps	Net realized and unrealized gain on derivatives	$	7,227		$	58,976
Mortgage loan commitments	Net realized and unrealized gain on derivatives	1			(105		)
Mortgage loan forward sale contracts	Net realized and unrealized gain on derivatives	(1		)	105

9. The Fair Value Option For Certain Loans

The Company has elected to measure certain long-term loans 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 18 for additional disclosures regarding the fair value of the fair value option loans.

Long-term loans 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 $1.3 million and $8.8 million at December 31, 2017 and September 30, 2017, respectively. The total unpaid principal balance of these long-term loans was approximately $978.9 million and $1.01 billion at December 31, 2017 and September 30, 2017, respectively. The fair value of these loans is included in total loans in the consolidated balance sheets and are grouped with commercial real estate, agricultural and commercial non-real estate loans in Note 4. As of December 31, 2017 and September 30, 2017, there were loans with a fair value of $14.1 million and $14.7 million, respectively, which were greater than 90 days past due or in nonaccrual status with an unpaid principal balance of $15.0 million and $17.0 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 income are as follows for the three months ended December 31, 2017 and 2016:



	Three Months Ended December 31, 2017						Three Months Ended December 31, 2016
	Noninterest Income			Total Changes in Fair Value			Noninterest Income			Total Changes in Fair Value

Notes to Consolidated Financial Statements (Unaudited)

For long-term loans, $1.0 million and $0.5 million for the three months ended December 31, 2017 and 2016, 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.

10. Core Deposits and Other Intangibles

A summary of intangible assets subject to amortization is as follows:



	Core Deposit Intangible			Brand Intangible			Other Intangible			Total
As of December 31, 2017	(dollars in thousands)
Gross carrying amount	$	7,339		$	8,464		$	538		$	16,341
Accumulated amortization	(1,847		)	(5,405		)	(141		)	(7,393		)
Net intangible assets	$	5,492		$	3,059		$	397		$	8,948

Net intangible assets	$	5,760		$	3,200		$	414		$	9,374

Amortization expense of intangible assets was $0.4 million and $0.8 million for the three months ended December 31, 2017 and 2016, respectively.

The estimated amortization expense of intangible assets assumes no activities, such as acquisitions, which would result in additional amortizable intangible assets. Estimated amortization expense of intangible assets in subsequent fiscal years is as follows:



	Amount
	(dollars in thousands)
Remaining in 2018	$	1,236
2019	1,538

11. Loan Servicing Rights

Loan servicing rights are created when residential mortgage loans are sold in the secondary market with the seller retaining the right to service those loans and receive servicing income over the life of the loan. The Company acquired loan servicing rights as a part of the HF Financial acquisition. The actual balance of loans being serviced for others are not reported as assets in the accompanying consolidated balance sheets.

The following table is the activity for loan servicing rights and the related valuation allowance for the three months ended December 31, 2017 and 2016:



	Three Months Ended

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 December 31, 2017, the constant prepayment rates (CPR) used to calculate the amortization averaged 12.0%. For valuation purposes, an average discount rate of 11.9% was utilized at December 31, 2017. Based on the Company's analysis of mortgage servicing rights, a $0.0 million valuation reserve was recorded at December 31, 2017, and a $0.1 million valuation reserve was recorded at September 30, 2017.

12. 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 $152.8 million and $139.3 million and fair value of approximately $149.8 million and $137.4 million at December 31, 2017 and September 30, 2017, 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 December 31, 2017 and September 30, 2017.

The line of credit has an interest rate of one month LIBOR plus 200 basis points, with interest payable monthly. There is also an unused line fee of 0.15% on the unused portion which is payable quarterly. The interest rate was 3.56% at December 31, 2017. There were no outstanding advances on this line of credit at December 31, 2017 and September 30, 2017.

As of December 31, 2017, the Company had a borrowing capacity of $1.69 billion with the Federal Reserve Board Discount Window ("FRB Discount Window"). Principal balances of loans pledged to FRB Discount Window to collateralize the borrowing totaled $1.99 billion at December 31, 2017 and $2.55 billion at September 30, 2017. The Company has secured this line for contingency funding.

As of December 31, 2017 and September 30, 2017, based on its Federal Home Loan Bank stock holdings, the combined aggregate additional borrowing capacity of the Company with the Federal Home Loan Bank was $1.40 billion and $1.55 billion, respectively.

14. Subordinated Debentures and Subordinated Notes Payable

Junior Subordinated Deferrable Interest Debentures

The Company has seven trusts which were created or assumed as part of the HF Financial and Sunstate Bank acquisitions that have issued and outstanding 73,400 shares, $1,000 par value, as of December 31, 2017 of Company Obligated Mandatorily Redeemable Preferred Securities (the "Preferred Securities"). These seven trusts were established and exist for the sole purpose of issuing 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

29-

Notes to Consolidated Financial Statements (Unaudited)

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. $73.5 million of Debentures were eligible for treatment as Tier 1 capital as of December 31, 2017 and September 30, 2017.

Relating to the trusts, the Company held as assets $2.5 million in common shares at December 31, 2017 and September 30, 2017 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 December 31, 2017, 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, to but excluding the maturity date or date of earlier redemption, the notes will bear interest at a rate per annum equal 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. Unamortized debt issuance costs related to these notes, which are included in Subordinated Debentures and Subordinated Notes Payable, totaled $0.2 million at December 31, 2017 and September 30, 2017. Proceeds from the private placement of subordinated notes repaid outstanding subordinated debt.

Subordinated debentures and subordinated notes payable are summarized as follows:

Notes to Consolidated Financial Statements (Unaudited)

At December 31, 2017, the Company had an income tax payable to the Internal Revenue Service (the "IRS") of $4.6 million, which is included in other liabilities on the consolidated balance sheets. At September 30, 2017, the Company had an income tax receivable from the IRS of $4.6 million, which is included in other assets on the consolidated balance sheets. The Company is no longer subject to U.S. federal, state and local or non-U.S. income tax examinations by tax authorities for years before 2014.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "Tax Reform Act"), was enacted into law. Beginning in 2018, the Tax Reform Act reduces the federal tax rate for corporations from 35% to 21% and changes or limits certain tax deductions. Because of the Company's September 30 fiscal year end, a blended statutory rate of 24.5% is applied to all net income before taxes generated during the current fiscal year. The new blended statutory rate reduced the provision for income taxes by approximately $5.0 million for the three months ended December 31, 2017. Another result of the lower corporate tax rate this quarter was the Company recording a revaluation discrete tax adjustment of $13.6 million to reduce its net deferred tax assets, which increased the provision for income taxes. The actual impact of the revaluing deferred taxes may vary from the estimated charge to provision of $13.6 million due to uncertainties in our preliminary estimates and the effect of further clarification of the new law that cannot be estimated at this time.

The Bank's effective tax rate for the three months ended December 31, 2017 was 49.5%, compared to 30.8% for the prior quarter. The increase in the effective tax rate during the quarter mostly resulted from the revaluation of deferred taxes. For 2018, the Bank expects its annual effective tax rate to be approximately 26%.

Uncertain tax positions were not significant at December 31, 2017 or September 30, 2017.

16. Employee Benefit Plans

Profit Sharing Plan

The Company participates in a multiple employer 401(k) profit sharing plan ("the 401(k) 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 $1.8 million and $1.5 million to the 401(k) Plan for the three months ended December 31, 2017 and 2016, respectively.

Defined Benefit Plan

The Company acquired a noncontributory (cash balance) defined benefit pension plan ("the Pension Plan") from HF Financial which covers former employees of HF Financial and its wholly-owned subsidiaries. Effective July 1, 2015, the Pension Plan was frozen which eliminates future contributions for qualified individuals.

On November 27, 2017, the Company's Board of Directors voted to terminate the Pension Plan, effective February 1, 2018. In order to settle its liabilities under the Pension Plan, the Company will offer participants the option to receive either an annuity purchased from an insurance carrier or a lump-sum cash payment. If the total $3.1 million value of the Pension Plan's cash assets is insufficient to cover the lump-sum payouts and annuity purchases, the Company will contribute the necessary funds to complete the termination of the Pension Plan. In addition to plan assets, the Company has a $2.3 million pension liability recorded as of December 31, 2017. The required final contribution is subject to a number of factors, including changes in interest rates and the exact proportion of participants electing a lump-sum distribution versus an annuity. The Company estimates that the total benefit payments will be $5.4 million as part of Pension Plan termination. At this time, the Company is unable to estimate the net income or expense associated with terminating the Pension Plan, but believes the amount will not be material to the financial statements.

The Company anticipates completing the transfer of all liabilities and administrative responsibilities under the Pension Plan by the end of fiscal third quarter 2018. Once this process is complete, the Company will no longer have any remaining pension obligations and thus no periodic pension expense.

17. 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

Notes to Consolidated Financial Statements (Unaudited)

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 stock 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 compensation is recognized based on the number of awards to vest using actual forfeiture amounts. 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 income. For the three months ended December 31, 2017 and 2016, stock compensation expense was $1.5 million and $1.6 million, respectively. Related income tax benefits recognized were $0.5 million and $0.6 million for the three months ended December 31, 2017 and 2016, respectively.

The following is a summary of the Plans’ restricted share and performance-based stock award activity as of December 31, 2017 and September 30, 2017. The number of performance shares granted is reflected in the below table at the amount of achievement of the pre-established targets.

18. 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

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. 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 mortgage-backed, states and political subdivisions, and other securities. Where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Level 3 securities were immaterial at December 31, 2017 and September 30, 2017.

Interest Rate Swaps and Loans

Interest rate swaps are valued by the Company's Swap Dealers using cash flow valuation techniques with observable market data inputs. 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 has entered into Collateral Agreements with its Swap Dealers and Futures Clearing Merchant which entitle it to receive collateral to cover market values on derivatives which are in asset position, thus a credit risk adjustment on interest rate swaps is not warranted. The Company regularly 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, the fair values of which are calculated by applying observable market values from Fannie Mae TBA pricing to each interest rate lock commitment and forward sales contract, therefore, are classified within Level 2 of the valuation hierarchy. The Company also has back-to-back swaps with loan customers, with corresponding swaps with an outside third party in exact offsetting terms.

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.

Other Repossessed Property

Other repossessed property consists of loan collateral that has been repossessed through foreclosure. This collateral is comprised of commercial and residential real estate and other repossessed assets. Other repossessed property 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.

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,

35-

Notes to Consolidated Financial Statements (Unaudited)

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.

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).

Property Held for Sale

This real estate property is carried in premises and equipment as property held for sale at fair value based upon the transactional price if available, or the appraised value of the property.

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 December 31, 2017 and September 30, 2017:



	Fair Value		Level 1		Level 2		Level 3

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

36-

Notes to Consolidated Financial Statements (Unaudited)

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 cash equivalents, 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 December 31, 2017 and September 30, 2017 are as follows:



		December 31, 2017				September 30, 2017
	Level in Fair Value Hierarchy	Carrying Amount		Fair Value		Carrying Amount		Fair Value

Subordinated debentures and subordinated notes payable	Level 2	108,343		108,097		108,302		108,293

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

Cash and cash equivalents: 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.

Cash Surrender Value of Life Insurance Policies: Fair value is equal to the cash surrender value of the life insurance policies.

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.

37-

Notes to Consolidated Financial Statements (Unaudited)

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.

19. 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. 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 and diluted earnings per share (EPS) for the three months ended December 31, 2017 and 2016:



	Three Months Ended
	December 31, 2017		December 31, 2016

Basic earnings per share	$	0.50	$	0.63
Diluted earnings per share	$	0.49	$	0.63

The Company had 0 and 50,076 shares of unvested performance stock as of December 31, 2017 and 2016, respectively, which were not included in the computation of diluted earnings per common share because performance conditions for vesting had not been met. The Company had 0 and 95,553 shares of anti-dilutive stock awards outstanding as of December 31, 2017 and 2016, respectively.

ITEM 2.	MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The historical consolidated financial data discussed below reflects our historical results of operations and financial condition and should be read in conjunction with our financial statements and related notes thereto presented elsewhere in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the fiscal year ended September 30, 2017, previously filed with the SEC. In addition to historical financial data, this discussion includes certain forward-looking statements regarding events and trends that may affect our future results. Such statements are subject to risks and uncertainties that could cause our actual results to differ materially. See “Cautionary Note Regarding Forward-Looking Statements.” For a more complete discussion of the factors that could affect our future results, see “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended September 30, 2017.

Any discrepancies included in this filing between totals and the sums of percentages and dollar amounts presented, or between rounded dollar amounts, are due to rounding.

Unless otherwise noted, references to "the current period" or "the current quarter" refer to the fiscal quarter ended December 31, 2017 and references to "the comparable period" or "the comparable quarter" refer to the fiscal quarter ended December 31, 2016.

Tax Equivalent Presentation

All references to net interest income, net interest margin, interest income on non ASC 310-30 loans, yield on non ASC 310-30 loans and the related non-GAAP adjusted measure of each item are presented on a fully-tax equivalent ("FTE") basis unless otherwise noted.

Overview

We are a full-service regional bank holding company focused on relationship-based business and agribusiness banking. We serve our customers through 173 branches in attractive markets in nine states: Arizona, Colorado, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota and South Dakota.

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) gain on the sale of loans held for sale (vi) gains on sales of securities; and (vii) 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) business development; (vii) FDIC insurance assessments; and (viii) 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 interest paid on interest-bearing liabilities in an effort to maximize net interest income while maintaining an appropriate level of interest rate risk.

Impact of the Tax Cuts and Jobs Act of 2017

The Tax Cuts and Jobs Act of 2017 significantly impacted the Company's financial results for the quarter and going forward. The three main impacts include:


•	A nonrecurring reduction in the carrying value of the Company's deferred taxes of $13.6 million, equating to $0.23, or 1.3%, of the Company's tangible book value per share and a reduction of approximately 15 basis points to the total capital ratio as of December 31, 2017 and $0.23 per diluted share for the quarter ended December 31, 2017;

•

A reduction in the statutory federal tax rate upon which the Company's net income before taxes is taxed beginning with the current fiscal year ending September 30, 2018. Because of the Company's fiscal year end, a blended statutory federal tax rate of 24.5% is applied to all net income before taxes generated during the current fiscal year and the overall effective tax rate for the fiscal year is expected to be approximately 26.0%. Compared to the previous statutory tax rate, the blended rate reduced the provision for income taxes by approximately $5.0 million for the quarter ended December 31, 2017. Beginning in fiscal year 2019, the Company's net income will be taxed at the 21.0% statutory federal tax rate; and

•

A reduction in the tax-related benefit generated by tax-advantaged assets. The tax equivalent adjustment to net interest income and net interest margin was $1.6 million for the current quarter, compared to $2.1 million in the prior quarter, on a consistent asset base. This change reduced net interest margin and adjusted net interest marginin the current quarterby approximately 2 basis points and increased our efficiency ratio by a negligible amount.

The actual impact of the revaluing deferred taxes may vary from the estimated charge to provision of $13.6 million due to uncertainties in our preliminary estimates and the effect of further clarification of the new law that cannot be estimated at this time. For more information on our tangible book value per share, net interest margin, adjusted net interest margin and efficiency ratio, including a reconciliation to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" section.

Correction of Prior Period Balances

The consolidated statements of income have been revised to correct an immaterial classification error in loan interest income and noninterest income related to credit card interchange income for all periods presented. The reclassification had no effect on net income, earnings per share, retained earnings or capital ratios for all periods presented; however, our net interest margin and adjusted net interest margin were reduced by seven to eight basis points compared to what was originally reported for the prior comparable periods presented. Periods not presented herein will be revised, as applicable, as they are included in future filings. For more information on the reclassification of credit card interchange income, see "—Notes to the Consolidated Financial Statements, Nature of Operations and Summary of Significant Policies" section.

Net income was $29.2 million, or $0.49 per diluted share, for the first quarter of fiscal year 2018, compared to $36.9 million, or $0.63 per diluted share, for the first quarter of fiscal year 2017. Adjusted net income, which excludes the effect of one-time acquisition expenses and the deferred taxes revaluation triggered by the Tax Cuts and Jobs Act of 2017, was $42.8 million, or $0.72 per diluted share, compared to $37.3 million, or $0.63 per diluted share, respectively, for the same periods, an increase of $5.5 million, or 14.7%. Compared to the first quarter of fiscal year 2017, total revenue (non-FTE) for the first quarter of fiscal year 2018 grew by 4.2%, provision for loan and lease losses were reduced 35.4% and noninterest expenses grew by 4.4%. Total revenue (non-FTE) is the sum of net interest income (non-FTE) and noninterest income. Our efficiency ratio was 45.8% and 45.1% for the quarters ending December 31, 2017 and December 31, 2016, respectively. For more information on our adjusted net income and efficiency ratio, including a reconciliation to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" section.

Net interest margin, which measures our ability to maintain interest rates on interest earning assets above those of interest bearing liabilities, was 3.89%, 3.93% and 3.82%, respectively, for the quarters ended December 31, 2017, September 30, 2017 and December 31, 2016. Adjusted net interest margin, which reflects the realized gain (loss) on interest rate swaps, was 3.80%, 3.82% and 3.65%, 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 marginincreased by 7 basis points and 15 basis points, respectively, compared to the same quarter in fiscal year 2017. The yield on interest-earning assets increased by 24 basis points over the same quarter in fiscal year 2017, driven by higher average loan balances as a proportion of

40-

earning assets and improving loan and investment yields. Meanwhile, the cost of interest-bearing liabilities increased by 18 basis points over the same period, including a 15 basis point increase in the cost of deposits, partially offset by a reduction in average FHLB borrowings outstanding. In addition, the reduction in the magnitude of the tax equivalent adjustment driven by a lower statutory tax rate reduced each metric by approximately 2 basis points. A $2.0 million reduction in the cost of interest rate swaps, that hedge the interest rate risk on long term fixed rate loans in the portfolio, compared to the prior comparable quarter is the primary driver of the more pronounced increase in adjusted net interest margin compared to net interest margin. 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.

Total loans were $9.17 billion at December 31, 2017 compared to $8.97 billion at September 30, 2017. The net growth of $196.8 million, or 2.2%, occurred primarily within the commercial real estate ("CRE") segment of the loan portfolio, which grew $170.9 million, including strong growth in owner-occupied CRE and construction loans. The agriculture loan segment increased by $55.2 million, with approximately $20 million of that growth resulting from short-term advances required by many of our dairy customers for tax planning purposes that have already been repaid.

Deposits grew to $9.02 billion at December 31, 2017, an increase of $46.6 million, or 0.5%, compared to $8.98 billion at September 30, 2017. Deposit growth was driven by $76.0 million increase in noninterest-bearing deposits, partially offset by a $29.4 million reduction in interest-bearing deposits, which is net of continued outflows of time deposits.

At December 31, 2017, loans graded "Watch" were $287.5 million, a decrease of $24.1 million, or 7.7%, compared to September 30, 2017. Loans graded "Substandard" were $247.7 million, an increase of $14.8 million, or 6.4%, over the same period. The decrease in "Watch" graded loans and the increase in "Substandard" graded loans was primarily driven by the deterioration of a small number of CRE relationships.

Nonaccrual loans, including ASC 310-30 loans, were $147.3 million as of December 31, 2017, with $4.1 million of the balance covered by FDIC loss-sharing agreements. Total nonaccrual loans increased by $9.0 million compared to September 30, 2017, primarily driven by one CRE loan relationship. Total other repossessed property balances were $10.5 million as of December 31, 2017, an increase of $1.5 million, or 16.7%, compared to September 30, 2017.

As of mid-January, annual reviews have been completed on approximately 70% of agriculture loan relationships with maturity dates between November 1, 2017 and January 15, 2018. Growers' 2017 performance was broadly in line with expectations and risk rating changes are expected to be minimal with upgrades modestly exceeding downgrades.

Provision for loan and lease losses was $4.6 million for the first quarter of fiscal year 2018, compared to $7.0 million for the same quarter of fiscal year 2017. Net charge-offs for the first quarter of fiscal year 2018 were $4.0 million, or 0.18% of average total loans on an annualized basis, with the majority of net charge-offs concentrated in the agriculture and commercial non-real estate segments of the loan portfolio. Net charge-offs were $4.9 million, or 0.22% of average total loans on an annualized basis for the first quarter of fiscal year 2017. The ratio of ALLL to total loans was 0.70% at December 31, 2017, a reduction from 0.71% at September 30, 2017. The balance of the ALLL increased from $63.5 million at September 30, 2017 to $64.0 million at December 31, 2017.

Our capital position is strong, with Tier 1 capital, total capital and Tier 1 leverage ratios of 11.3%, 12.3% and 10.3%, respectively, at December 31, 2017, compared to 11.4%, 12.5% and 10.3%, respectively, at September 30, 2017. In addition, our Common Equity Tier 1 ratio was 10.5% at December 31, 2017 and 10.7% at September 30, 2017. Our tangible common equity to tangible assets ratio was 9.2% at December 31, 2017 and 9.2% at September 30, 2017. The revaluation of the Company's deferred taxes reduced the total capital ratio by approximately 15 basis points.

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, 2017, our business, financial condition and results of operations are impacted by several key factors, including economic conditions, interest rates, asset quality and loss-sharing agreements, banking laws and regulations, competition, operational efficiency, goodwill and amortization of other intangible assets and loans and interest rate swaps accounted for 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 three months ended December 31, 2017.

Net interest income was $102.2 million for the first quarter of fiscal year 2018, compared to $99.0 million for the same quarter in fiscal year 2017, an increase of 3.2%. The increase in net interest income was primarily attributable to higher loan interest income driven by 3.3% of growth in average loans outstanding between periods and a modest increase in investment portfolio income driven by rising interest rates, partially offset by higher interest expense associated with interest-bearing deposits and borrowings.

Net interest margin was 3.89% for the first quarter of fiscal year 2018, an increase of 7 basis points compared to the same quarter in fiscal year 2017. Adjusted net interest margin was 3.80% for the first quarter of fiscal year 2018, an increase of 15 basis points compared to the same quarter in fiscal year 2017. The yield on interest-earning assets increased by 24 basis points over the same quarter in fiscal year 2017, driven by higher average loan balances as a proportion of earning assets and improving loan and investment yields. Meanwhile, the cost of interest-bearing liabilities increased by 18 basis points over the same period, including a 15 basis point increase in the cost of deposits, partially offset by a reduction in average FHLB borrowings outstanding. In addition, the reduction in the magnitude of the tax equivalent adjustment driven by a lower statutory tax rate reduced each metric by approximately 2 basis points. A $2.0 million reduction in the cost of interest rate swaps, that hedge the interest rate risk on long term fixed rate loans in the portfolio, compared to the prior comparable quarter is the primary driver of the more pronounced increase in adjusted net interest margin compared to net interest margin. For more information on our adjusted net interest income and adjusted net interest margin, including a reconciliation of each to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" section.

The following tables present 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 month periods, respectively. 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 $735.7 million at December 31, 2017 and $724.1 million at December 31, 2016, 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.

Interest and Dividend Income

The following table presents interest and dividend income for the three month periods ended December 31, 2017 and 2016:



	Three Months Ended
	December 31, 2017		December 31, 2016
	(dollars in thousands)
Interest and dividend income:
Loans (FTE)	$	109,245	$	102,074

Less: Tax equivalent adjustment	1,565		2,142
Total interest and dividend income (GAAP)	$	114,954	$	106,655

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 $116.5 million for the first quarter of fiscal year 2018, compared to $108.8 million for the same quarter of fiscal year 2017, an increase of 7.1%. Significant components of interest and dividend income are described in further detail below.

Loans. Average net loan balances for the first quarter of fiscal year 2018 were $8.93 billion, representing a 3.3% increase compared to the same period in fiscal year 2017. Interest income on all loans increased to $109.2 million in first quarter of fiscal year 2018 from $102.1 million in the same quarter in fiscal year 2017, an increase of $7.1 million, or 7.0% between the two periods.

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 4.78% for the first quarter of fiscal year 2018, an increase of 13 basis points compared to the same quarter in fiscal year 2017. 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 4.67% for the first quarter of fiscal year 2018, a 23 basis point an increase compared to the same quarter in fiscal year 2017. In addition, the reduction in the magnitude of the tax equivalent adjustment driven by a lower statutory tax rate reduced each metric by approximately 2 basis points. Starting in first quarter of fiscal year 2016 and continuing through the first quarter of 2018 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 and benchmark rate hikes which have raised interest rates on many of our floating and variable rate loans.

The average duration, net of interest rate swaps, of the loan portfolio was 1.2 years as of December 31, 2017. Approximately 47%, or $4.33 billion, of the portfolio is comprised of fixed rate loans, of which $980.1 million 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 and variable rate loans in the portfolio, approximately 51% are indexed to Wall Street Journal Prime, 28% to 5-year Treasuries and the balance to various other indices. Approximately 2% of our total loans' rates are floored, with an average interest rate floor 71 bps above market rates.

Loan-related fee income of $2.0 million is included in interest income for the first quarter of fiscal year 2018 and $1.4 million for the same quarter in fiscal year 2017. 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 $0.9 million for the first quarter of fiscal years 2018 and 2017, 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 December 31, 2017. Interest and dividend income on investments includes income earned on investment securities and FHLB stock. Interest and dividend income on investments was $7.0 million for the first quarter of fiscal year 2018, an increase of $0.6 million, or 10.4%, from $6.4 million in the first quarter of fiscal year 2017, driven by an increase in average balances coupled with a yield increase from 1.84% to 1.97% over the same period.

45-

The weighted average life of the investment portfolio was 3.6 years at December 31, 2017 and September 30, 2017. Average investments represented 13.6% and 13.4% of total average interest-earning assets for the first quarters of fiscal years 2018 and 2017, respectively.

Interest Expense

The following table presents interest expense for the three month periods ended December 31, 2017 and 2016:



	Three Months Ended
	December 31, 2017		December 31, 2016
	(dollars in thousands)
Interest expense:
Deposits	$	10,998	$	7,290
Securities sold under agreements to repurchase	95		115
FHLB advances and other borrowings	2,069		1,271
Subordinated debentures and subordinated notes payable	1,170		1,088
Total interest expense	$	14,332	$	9,764

Total interest increased $4.6 million, or 46.8%, to $14.3 million in the first quarter of fiscal year 2018 from $9.8 million in the same quarter in fiscal year 2017. Significant components of interest expense are described in further detail below.

Deposits. Interest expense on deposits, consisting of checking accounts, money market accounts, NOW accounts, savings accounts and time deposits, was $11.0 million and $7.3 million for the first quarter of fiscal year 2018 and 2017, respectively, an increase of $3.7 million, or 50.9%, driven by growth in average interest-bearing deposits outstanding and increasing benchmark interest rates. Average deposit balances increased to $9.00 billion from $8.69 billion, for the same periods, an increase of $0.31 billion, or 3.6%. The cost of deposits increased to 0.48% for the first quarter of fiscal year 2018 from 0.33% for the same quarter of fiscal year 2017.

Average non-interest-bearing demand account balances remained stable at 20.5% of average total deposits for the first quarter of fiscal year 2018 and 20.6% for the comparable quarter in fiscal year 2017. Total average other liquid accounts, consisting of money market and savings accounts, increased to 65.4% of total average deposits for the first quarter of fiscal year 2018, compared to 63.9% of total average deposits for the comparable quarter in fiscal year 2017, while time deposit accounts decreased to 14.1% of average total deposits for the first quarter of fiscal year 2018, compared to 15.5% in the comparable quarter in fiscal year 2017. We continue our strategy of focusing on cost-effective transaction accounts as well as our focus on gathering business deposits, which are typically transaction accounts by nature.

FHLB Advances and Other Borrowings. Interest expense on FHLB advances and other borrowings was $2.1 million for the first quarter of fiscal year 2018, an increase of $0.8 million, or 62.7%, compared to $1.3 million for the comparable quarter in 2017, reflecting a weighted average cost of 1.58% and 0.70% for the first quarters of fiscal years 2018 and 2017, respectively. Our average balance for FHLB advances and other borrowings was $519.6 million in the current quarter of fiscal year 2018, a $197.4 million reduction, compared to $717.0 million in the comparable quarter of fiscal year 2017. Average FHLB advances and other borrowings as a proportion of total average interest-bearing liabilities were 5.3% for the first quarter of fiscal year 2018, compared to 7.4% for the comparable quarter in fiscal year 2017. 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. The weighted average contractual rate paid on our FHLB advances was 1.57% and 0.83% at December 31, 2017 and 2016, respectively, and the average tenor was 3 and 61 months for the same periods.

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 December 31, 2017, we had pledged $3.77 billion of loans to the FHLB, against which we had borrowed $721.0 million.

46-

Subordinated Debentures and Subordinated Notes Payable. Interest expense on our outstanding subordinated debentures and subordinated notes payable was $1.2 million in first quarter of fiscal year 2018 and $1.1 million in the comparable quarter in fiscal year 2017. The weighted average contractual rate on outstanding subordinated notes was 4.88% at both December 31, 2017 and September 30, 2017.

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 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.

Provision for Loan and Lease Losses

We recognized provision for loan and lease losses of $4.6 million for the first quarter of fiscal year 2018 compared to a provision for loan and lease losses of $7.0 million for the comparable quarter in fiscal year 2017, a decrease of $2.4 million between the periods, or 35.4%. The decrease in provision was driven primarily by lower specific reserves in the agriculture and commercial non-real estate segments of the loan portfolio. We recorded a $0.1 million net improvement in provision for ASC 310-30 loans for the first quarter of fiscal year 2018, compared to a net impairment in provision of $0.1 million for the comparable quarter in fiscal year 2017.

Total Credit-Related Charges

In addition to the lower provision for loan losses we incurred during the current fiscal quarter of 2018 compared to the same quarter in 2017, we recognized other credit-related charges. We believe that the following table, which summarizes each component of the total credit-related charges incurred during the current, prior and comparable quarter, is helpful to understanding the overall impact on our quarterly results of operations. Net other repossessed property charges includes other repossessed property operating costs, valuation adjustments and (loss) gain on sale of other repossessed properties, each of which entered other repossessed property 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.

Noninterest Income

The following table presents noninterest income for the three month periods ended December 31, 2017 and 2016:



	Three Months Ended
	December 31, 2017			December 31, 2016
	(dollars in thousands)
Non-interest income:
Service charges and other fees	$	13,178		$	13,837

Net realized and unrealized gain on derivatives	7,227			58,976
Subtotal, loans at fair value and related derivatives	(1,438		)	(5,025		)
Total noninterest income	$	16,674		$	15,658

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 $16.7 million for the first quarter of fiscal year 2018, compared to $15.7 million for the comparable quarter in fiscal year 2017, an increase of $1.0 million, or 6.5%. Significant components of noninterest income are described in further detail below.

Product and Service Fees. We recognized $18.1 million of noninterest income related to product and service fees in the first quarter of fiscal year 2018, a decrease of $2.6 million, or 12.4%, compared to the same quarter in fiscal year 2017. The decrease was primarily attributable to a $1.0 million decrease in mortgage banking income, a $0.8 million decrease in other income, and a $0.7

48-

million decrease in service charges and other fees, which reflected a modest decrease primarily driven by the full quarter impact of the "Durbin Amendment" limit on debit card interchange income that became effective in July 2017.

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 first quarter of fiscal year 2018, these items accounted for $(1.4) million of noninterest income compared to $(5.0) million for the same quarter in fiscal year 2017. The change was driven by a net favorable change in the credit adjustment of $1.6 million combined with a $2.0 million reduction in the current cost of interest rate swaps driven by changes in the interest rate environment. 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.

Noninterest Expense

The following table presents noninterest expense for the three month periods ended December 31, 2017 and 2016:



	Three Months Ended
	December 31, 2017		December 31, 2016
	(dollars in thousands)
Noninterest expense:
Salaries and employee benefits	$	32,868	$	31,634

Acquisition expenses	—		710
Other	4,329		3,347
Total noninterest expense	$	54,868	$	52,537

Our noninterest expense consists primarily of salaries and employee benefits, data processing, occupancy expenses, professional fees, communication expenses, advertising and acquisition expenses. Noninterest expense was $54.9 million in the first quarter of fiscal year 2018 compared to $52.5 million for the same quarter in fiscal year 2017, an increase of $2.3 million, or 4.4%. Included in noninterest expense for the first quarter of fiscal year 2017 was $0.7 million of non-recurring acquisitions expenses; absent this reduction, total noninterest expense increased by $3.0 million, or 5.9%, over the same period. This increase was primarily attributable to a $1.4 million increase in professional fees primarily driven by an increase in our FDIC assessment, a $1.2 million increase in salaries and employee benefits and a $1.0 million increase in other expenses, partially offset by a decrease of $0.4 million in net loss recognized on repossessed property and other related expenses.

Our efficiency ratio was 45.8% and 45.1% for the three month periods ending December 31, 2017 and 2016, respectively. For more information on our efficiency ratio, including a reconciliation 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 $28.6 million for the first quarter of fiscal year 2018 represents an effective tax rate of 49.5%, compared to a provision of $16.1 million or an effective tax rate of 30.3% for the comparable quarter. Excluding the deferred taxes revaluation as a result of the Tax Reform Act of 2017, the effective tax rate was 26.0%. For more information on the impact of the deferred taxes adjustment, see "—Overview, Impact of the Tax Cuts and Jobs Act of 2017" section.

²This is a non-GAAP financial measure we believe is helpful to interpreting our financial results. For more information on this non-GAAP financial measure, including a reconciliation to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" section.
³ Annualized for partial-year periods, except for September 30, 2017, which was for the twelve month period.

Our total assets were $11.81 billion at December 31, 2017, compared with $11.69 billion at September 30, 2017. The increase in total assets during the first three months of fiscal year 2018 was principally attributable to an increase in net loans of $196.3 million since September 30, 2017, partially offset by a decrease in cash and cash equivalents of $62.8 million for the same period. At December 31, 2017, loans were $9.17 billion, compared to $8.97 billion at September 30, 2017. Net loan growth was primarily driven by growth in CRE and agriculture segments of the loan portfolio, offset by a reduction in commercial non-real estate loans. During the first quarter of fiscal year 2018, total deposits grew by $46.6 million, or 0.5%. The growth was driven by a $76.0 million increase in noninterest-bearing deposits, partially offset by a $29.4 million reduction in interest-bearing deposits, which is net of continued outflows of time deposits.

¹Unpaid principal balance for commercial non-real estate, agriculture and commercial real estate loans includes fair value adjustments associated with long-term fixed-rate loans where we have entered into interest rate swaps to hedge our interest rate risk.

During the first quarter of fiscal year 2018, total loans increased by 2.2%, or $196.8 million. The growth was primarily focused in CRE and agriculture segments of the loan portfolio, which grew $170.9 million and $55.2 million, respectively, offset by a reduction of $23.2 million in commercial non-real estate loans. Over the same time period, residential real estate, consumer and other loan balances remained generally stable.

Total unpaid principal balance	$	9,201,926

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 lending specifically, and to CRE lending in general, by targeting relationships with sound management and financials which are priced to reflect the amount of risk we accept as the lender.

Agriculture. Agriculture loans include farm operating loans and loans collateralized by farm land. According to the American Banker's Association, at September 30, 2017, we were ranked the sixth-largest farm lender bank in the United States measured by total dollar volume of farm loans. We consider agriculture lending one of our core competencies. 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 over recent years, we believe there continues to typically be strong secondary

52-

sources of repayment and low borrower leverage for the agriculture loan portfolio. Continued pressure on commodity prices or a further downturn in the agriculture economy could directly and adversely affect our agricultural loan portfolio and indirectly and adversely impact other lending categories including commercial non-real estate, CRE, residential real estate and consumer.

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 and variable rate loans with interest rate swaps over a wide range of terms, and variable-rate loans with varying terms. Our bank's direct exposure to energy-related borrowers is less than 1.4% of total loans.

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 some jumbo products, adjustable-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.

Other Repossessed Property

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. Other repossessed property 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 other repossessed property carrying value was $10.5 million as of December 31, 2017, an increase of $1.5 million, or 16.7%, compared to September 30, 2017. The following table presents our other repossessed property 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. Since September 30, 2017, the fair value of the portfolio has decreased by $1.3 million, or 0.1%.

The following table presents 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 held at December 31, 2017. 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 ("WA 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 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, other repossessed property, restructured performing loans and accruing loans over 90 days past due, at the end of the dates indicated. Loans covered by FDIC loss-sharing agreements 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 agreement through June 4, 2020 for single-family real estate loans.

At December 31, 2017 and September 30, 2017, our nonperforming assets were 1.34% and 1.26%, respectively, of total assets. Nonaccrual loans were $147.3 million as of December 31, 2017, with $4.1 million of the balance covered by FDIC loss-sharing agreements, which represented a total increase in nonaccrual loans of $9.0 million, or 6.5%, compared to September 30, 2017. Total other repossessed property balances were $10.5 million as of December 31, 2017, an increase of $1.5 million, or 16.7%, compared to September 30, 2017.

We recognized approximately $0.2 million of interest income on loans that were on nonaccrual for the first quarter of fiscal year 2018. Excluding loans covered by FDIC loss-sharing agreements, we had average nonaccrual loans (calculated as a two-point average) of $138.3 million outstanding during the first quarter of fiscal year 2018. Based on the average loan portfolio yield for these loans for the first quarter of fiscal year 2018, we estimate that interest income would have been $1.7 million higher during this period had these loans been accruing.

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.

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").

The table below outlines total TDRs, split between performing and nonperforming loans, at each of the dates indicated:

As of December 31, 2017, total performing TDRs decreased $0.1 million, or 0.4%, compared to September 30, 2017. Total nonperforming TDRs decreased $7.3 million, or 10.2%, compared to September 30, 2017 due mainly to partial charge offs on two relationships and a substantial paydown from one relationship in our agriculture portfolio during the quarter.

We entered into loss-sharing agreements with the FDIC related to certain assets (loans and other repossessed property) acquired from TierOne Bank on June 4, 2010. We are generally indemnified by the FDIC at a rate of 80% for any future credit losses through June 4, 2020 for single-family real estate loans and other repossessed property. Our commercial loss-sharing agreement with the FDIC has expired.

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 and the value of the underlying collateral as supported by third party appraisals, broker’s price opinions, and/or the borrower’s financial statements and internal valuation assessments, 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.

¹Loans include unpaid principal balance net of unamortized discount on acquired loans and unearned net deferred fees and costs and loans in process.
²Nonaccruing loans excludes loans covered by FDIC loss-sharing agreements.
³Annualized for partial-year periods

In the first quarter of fiscal year 2018, net charge-offs were $4.0 million, or 0.18% of average total loans on an annualized basis, comprised of $4.6 million of charge-offs and $0.6 million of recoveries. For fiscal year 2017, net charge-offs were $22.7 million, or 0.26%, of average total loans.

At December 31, 2017, the allowance for loan and lease losses was 0.70% of our total loan portfolio, a 1 basis point decrease compared to 0.71% at September 30, 2017. The balance of the ALLL increased to $64.0 million from $63.5 million over the same period.

Additionally, a portion of our loans which are carried at fair value, totaling $980.1 million at December 31, 2017 and $1.02 billion at September 30, 2017, 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 $6.2 million and $8.3 million at December 31, 2017 and September 30, 2017, respectively, or 0.07% and 0.09% of total loans, respectively. Finally, total purchase

discount remaining on all acquired loans equates to 0.29% and 0.32% of total loans at December 31, 2017 and September 30, 2017, respectively.

The following table presents 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 makes 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 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 at December 31, 2017 and September 30, 2017.

Deposits

We obtain funds from depositors by offering consumer and business demand deposit accounts, money market accounts, NOW accounts, savings accounts and term time deposits. At December 31, 2017 and September 30, 2017, our total deposits were $9.02 billion and $8.98 billion, respectively, representing an increase of 0.5%, which was primarily spread across 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 time deposits toward demand, NOW, money market and savings accounts in recent years.

The following table presents the balances and weighted average cost of our deposit portfolio at the following dates:

Derivatives

In 2017, we began a new program of selling interest swaps directly to customers. These interest rate swaps sales are used to enable customers to achieve a long-term fixed rate by selling the customer a long-term variable rate loan indexed to LIBOR plus a credit spread whereby the Bank enters into an interest rate swap with our customer where the customer pays a fixed rate of interest set at the time of origination on the interest rate swap and then the customer receives a floating rate equal to the rate paid on the loan, thus resulting in a fixed rate of interest over the life of the interest rate swap. We then enter into a mirrored interest rate swap with a swap dealer where we pay and receive the same fixed and floating rate as we pay and receive from the interest rate swap we have with our customer. As the interest paid and received by us on the two swaps net to zero, we are left with the variable rate of the long-term loan.

Prior to 2017 we entered 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 mitigated 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 elected to account for the loans at fair value under ASC 825 Fair Value Option. 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

60-

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.

Short-Term Borrowings

Our primary sources of short-term borrowings include securities sold under repurchase agreements and certain FHLB advances maturing within 12 months. The following table presents certain information with respect to only our borrowings with original maturities less than 12 months at and for the periods noted:

We have a $10.0 million revolving line of credit with a large national bank, which expires July 28, 2018, at an interest rate of one month LIBOR plus 200 basis points. At December 31, 2017, we did not have any advances on the line of credit.

Other Borrowings

We have outstanding $75.9 million of junior subordinated debentures to affiliated trusts in connection with the issuance of trust preferred securities by such trusts as of December 31, 2017 and September 30, 2017. We are permitted under applicable laws and regulations to count these trust preferred securities as part of our Tier 1 capital.

In 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 December 31, 2017, have an interest rate of 4.875% per annum, payable semi-annually on each February 15 and August 15, commencing on February 15, 2016 until August 15, 2020. During the first quarter of fiscal year 2018, we incurred $1.2 million in interest expense on all outstanding subordinated debentures and notes compared to $1.1 million in the same period in fiscal year 2017.

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:



	December 31, 2017		September 30, 2017

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.

62-

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. We also acquire brokered deposits when the cost of funds is advantageous to other funding sources.

Great Western Bancorp, Inc. Our 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 December 31, 2017, our holding company had $53.4 million of cash. During the first quarter of fiscal year 2018, we declared and paid a dividend of $0.20 per common share. The outstanding amounts under our revolving line of credit with a large retail bank and our private placement subordinated capital notes together totaled $35.0 million at December 31, 2017. 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 December 31, 2017, our bank had cash of $297.6 million and $1.37 billion of highly-liquid securities held in our investment portfolio, of which $990.6 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 had $721.0 million in FHLB borrowings at December 31, 2017, with additional available lines of $1.40 billion. Our bank also had an additional borrowing capacity of $1.69 billion with the FRB Discount Window. 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 December 31, 2017, we had a total of $2.57 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.

The following table presents our regulatory capital ratios at December 31, 2017 and the standards for both well-capitalized depository institutions and minimum capital requirements. Our capital ratios exceeded applicable regulatory requirements as of that date.

Risk-weighted assets	9,889,986

At December 31, 2017 and September 30, 2017, our Tier 1 capital included an aggregate of $73.5 million of trust preferred securities issued by our subsidiaries. At December 31, 2017, our Tier 2 capital included $64.0 million of the allowance for loan and lease losses and $35.0 million of private placement subordinated capital notes. At September 30, 2017, our Tier 2 capital included $63.5 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 $9.89 billion at December 31, 2017.

The revaluation of the Company's deferred taxes reduced the total capital ratio by approximately 15 basis points.

Non-GAAP Financial Measures

We rely on certain non-GAAP measures in making financial and operational decisions about our business. 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. We disclose net interest income and related ratios and analysis on a taxable-equivalent basis, which may also be considered non-GAAP financial measures. We believe this presentation to be the preferred industry measurement of net interest income as it provides a relevant comparison of net interest income arising from taxable and tax-exempt sources. In addition, certain performance measures, including the efficiency ratio and net interest margin utilize net interest income on a taxable-equivalent basis.

In particular, we evaluate our profitability and performance based on our adjusted net income, adjusted earnings per common share, tangible net income and return on average tangible common equity. Our adjusted net income and adjusted earnings per common 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 as well as the effect of revaluation of deferred taxes). Our tangible net income and return on average 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 applicable period (for tangible 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.

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 calculation of this ratio excludes the effect of our 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.

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.

Recent Accounting Pronouncements

See "Note 2. New Accounting Pronouncements" in the accompanying "Notes to Unaudited Consolidated Financial Statements" included in this report for a discussion of new accounting pronouncements and their expected impact on our financial statements.

Critical Accounting Policies and the Impact of Accounting Estimates

There have been no material changes to our critical accounting policies and accounting estimates from those disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2017.


ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of December 31, 2017, 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, 2017.

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 December 31, 2017 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.

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 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.

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.

PART II. OTHER INFORMATION


ITEM 1.	LEGAL PROCEEDINGS

From time to time we are a party to various litigation and regulatory matters incidental to the conduct of our business. We establish reserves for such matters when potential losses become probable and can be reasonably estimated. We believe the ultimate resolution of existing litigation and regulatory matters will not have a material adverse effect on our financial condition, results of operations or cash flows. However, changes in circumstances or additional information could result in additional accruals or resolution of these matters in excess of established accruals, which could adversely affect our financial condition, results of operations or cash flows, potentially materially.
