CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

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

- 3-

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

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

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

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

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

• declines in the market prices for agricultural products;

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

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

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

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

• changes in the demand for our products and services;

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

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

• our ability to attract and retain customer deposits;

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

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

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

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

• our ability to keep pace with technological changes;

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

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

• the effects of problems encountered by other financial institutions;

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

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

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

- 4-

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

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

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

• the effect of NAB’s control over us as a result of its continuing beneficial ownership of our outstanding common stock;

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

• our ability to meet our obligations as a public company, including our obligations under Section 404 of the Sarbanes-Oxley Act of 2002;

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

• damage to our reputation from any of the factors described above, in “Item 1A. Risk Factors” or in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

The foregoing factors should not be considered an exhaustive list and should be read together with the other cautionary statements included in this Quarterly Report on Form 10-Q, our Annual Report on Form 10-K for the fiscal year ended September 30, 2014 and our Quarterly Report on Form 10-Q for the period ended December 31, 2014. If one or more events related to these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may differ materially from what we anticipate. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and we do not undertake any obligation to update or review any forward-looking statement, whether as a result of new information, future developments or otherwise.

GREAT WESTERN BANCORP, INC.

Notes to Consolidated Financial Statements (Unaudited)

1. Basis of Presentation

Great Western Bancorp, Inc. (the “Company”) is a bank holding company organized under the laws of Delaware. The primary business of the Company is ownership of its wholly owned subsidiary, Great Western Bank (the “Bank”). The Bank is a full-service regional bank focused on relationship-based business and agribusiness banking in Arizona, Colorado, Iowa, Kansas, Missouri, Nebraska, 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. The Company was a majority owned indirect subsidiary of National Australia Bank Limited (“NAB”) at March 31, 2015.

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 other than the reclassifications outlined below.

The unaudited interim consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ending September 30, 2014, which includes a description of significant accounting policies. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year or any other period.

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

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

On May 6, 2015, NAB sold 23.0 million shares of the Company's common stock, representing 39.7% of the Company's common stock, in the second stage of its planned divestment. After completion of the offering, NAB beneficially owns 28.5% of the Company's outstanding common stock.

On April 28, 2015, the board of directors of the Company declared a dividend of $0.12 per common share payable on May 29, 2015 to owners of record as of close of business on May 15, 2015.

Changes in the Presentation of Results for Loans at Fair Value and Related Derivatives

In the normal course of business, the Company manages interest rate risk by entering into fixed-to-floating interest rate swaps related to all fixed-rate loans with original terms longer than five years. The Company has elected to account for these loans using the Fair Value Option. During the first quarter of fiscal year 2015, the Company identified an immaterial error in its reporting of one aspect of the derivatives related to these loans and also elected to change the presentation of the reported changes in fair value of these loans and related derivatives, each as discussed below. The Company's previous consolidated financial statements have been corrected or reclassified, as appropriate, to be consistent with the accompanying unaudited consolidated financial statements.

During the first quarter of fiscal year 2015, the Company identified that the current realized gain (loss) on the derivatives related to fair value loans has been improperly recorded as loan interest income instead of being presented in the same line item as the unrealized gain (loss) on the derivatives. As such, the realized gain (loss) on the derivatives related to fair value loans has been moved from loan interest income to "Net realized and unrealized gain (loss) on derivatives" within noninterest income. The Company has determined these corrections to be immaterial to the prior period financial statements and there was no effect on net income, equity or cash flows. The following table reflects the impact of the matter described above on previously filed financial statements:

Additionally, the Company previously reported the changes in fair value of these loans related to both interest rates and credit quality in interest income and the Company presented the changes in fair value of the derivatives in noninterest expense. Changes in fair value related to interest rates on the loans and changes in fair value of the derivatives were completely offset in any reporting period. To improve the clarity and comparability of its financial statements, the Company has elected to change its presentation of the changes in fair value related to these loans and derivatives by presenting these changes in two separate line items in noninterest income. As such, changes in fair value related to these loans, both related to interest rates and credit quality, is presented in "Net increase (decrease) in fair value of loans at fair value"within noninterest income, and changes in fair value related to these derivatives is presented in "Net realized and unrealized gain (loss) on derivatives" within noninterest income. The following table reflects the impact of the matter described above on previously filed financial statements:

Proceeds from sales of securities available for sale were $0 and $4.5 million for the three months ended March 31, 2015 and 2014, respectively, and $55.1 million and $4.5 million for the six months ended March 31, 2015 and 2014, respectively. There were no gross gains or gross losses realized on sales for the three months ended March 31, 2015 and 2014, using the specific identification method. Gross gains of $0.6 million and $0 and gross losses of $0.5 million and $0 were realized on the sales for the six months ended March 31, 2015 and 2014, respectively, also using the specific identification method.

Securities with a carrying value of approximately $1,174.9 million and $1,132.3 million at March 31, 2015 and September 30, 2014, 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 40% and 64% of the Company’s investment portfolio at March 31, 2015 and September 30, 2014, respectively, are reported in the consolidated financial statements at an amount less than their amortized cost. Based on evaluation of available evidence, including recent changes in market interest rates, credit rating information, implicit or explicit government guarantees, and information obtained from regulatory filings, management believes the declines in fair value of these securities are temporary. As the Company does not intend to sell the securities and it is not more likely than not that the Company will be required to sell the securities before the recovery of their amortized cost basis, which may be maturity, the Company does not consider the securities to be other than temporarily impaired at March 31, 2015 or September 30, 2014. The Company did not recognize any other-than-temporary impairment for the three and six months ended March 31, 2015 and 2014.

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

September 30, 2014. Interest income recognized on impaired loans for the three months ended March 31, 2015 and 2014 totaled $1.8 million and $2.1 million, respectively and $4.8 million and $3.3 million for the six months ended March 31, 2015 and 2014, respectively.

Valuation adjustments made to repossessed properties for the three months ended March 31, 2015 and 2014, totaled $2.2 million and $0.5 million, respectively, and $4.3 million and $1.0 million for the six months ended March 31, 2015 and 2014, respectively. The adjustments are included in other noninterest expense.

Troubled Debt Restructured Loans

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 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 losses for TDRs were $2.7 million and $3.2 million at March 31, 2015 and September 30, 2014, respectively. Commitments to lend additional funds to borrowers whose loans were modified in a TDR were not significant as of March 31, 2015 or September 30, 2014.

The following table presents the recorded value of the Company’s TDR balances as of March 31, 2015 and September 30, 2014 (in thousands):

7. Accounting for Certain Loans Acquired with Deteriorated Credit Quality

In June 2010, the Company acquired certain loans that had deteriorated credit quality. Loan accounting specific to these purchased impaired loans addresses differences between contractual cash flows expected to be collected from the initial investment in loans if those differences are attributable, at least in part, to credit quality. Several factors were considered when evaluating whether a loan was considered a purchased impaired loan, including the delinquency status of the loan, updated borrower credit status, geographic information, and updated loan-to-values (“LTV”). U.S. GAAP allows purchasers to aggregate purchased 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, homogenous 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 homogenous loans. The re-assessment of purchased impaired loans resulted in the following changes in the accretable yield during the three and six months ended March 31, 2015 and 2014 (in thousands):

	Three Months Ended March 31,						Six Months Ended March 31,
	2015			2014			2015			2014
Balance at beginning of period	$	46,342		$	58,411		$	50,889		$	67,660

Disposals	—			—			(80		)	(4,819		)
Balance at end of period	43,431			56,415			43,431			56,415

The reclassifications from nonaccretable difference noted in the table above represent instances where specific pools of loans are expected to perform better over the remaining lives of the loans than expected at the prior re-assessment date.

8. FDIC Indemnification Asset

Under the terms of the purchase and assumption agreement with the FDIC with regard to the TierOne Bank acquisition, the Company is reimbursed for a portion of the losses incurred on covered assets. As covered assets are resolved, whether it be through repayment, short sale of the underlying collateral, the foreclosure on or sale of collateral, or the sale or charge-off of loans or OREO, any differences between the carrying value of the covered assets versus the payments received during the resolution process, that are reimbursable by the FDIC, are recognized as reductions in the FDIC indemnification asset. Any gains or losses realized from the resolution of covered assets reduce or increase, respectively, the amount recoverable from the FDIC. The following table represents a summary of the activity related to the FDIC indemnification asset for the three and six months ended March 31, 2015 and 2014 (in thousands):

	Three Months Ended March 31,						Six Months Ended March 31,

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.

9. Derivative Financial Instruments

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

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

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 is similar to those relating to traditional on-balance sheet financial instruments. The Company manages interest rate swap credit risk with the same standards and procedures applied to its commercial lending activities. Amounts due from NAB to reclaim cash collateral under the interest rate swap master netting arrangements have not been offset against the derivative balances. These receivables are classified on the consolidated balance sheets as cash and were $0 as of March 31, 2015 and September 30, 2014, respectively.

The effect of derivatives on the consolidated statements of comprehensive income for the three and six months ended March 31, 2015 and 2014 (in thousands) was as follows:

Mortgage loan forward sale contracts	Noninterest income	(13		)	(31		)	(27		)	(34		)

Netting of Derivatives

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

The table below shows total gross derivative assets and liabilities which are adjusted on an aggregate basis, where applicable to take into consideration the effects of legally enforceable master netting agreements for the net reported amount in the consolidated balance sheets. These amounts are offset on the consolidated balance sheets.

10. The Fair Value Option

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

See Note 17 for additional disclosures regarding the fair value of the fair value option loans and written loan commitments.

Long-term loans and written loan commitments for which the fair value option has been elected had a net favorable difference between the aggregate fair value and the aggregate unpaid loan principal balance and written loan commitment amount of approximately $43.3 million and $7.1 million at March 31, 2015 and September 30, 2014, respectively. The total unpaid principal balance of these long-term loans was approximately $1,017.3 million and $978.3 million at March 31, 2015 and September 30, 2014, respectively. The fair value of these loans and written loan commitments is included in total loans in the consolidated balance sheets and are grouped with commercial non real estate, commercial real estate, and agricultural loans in Note 5. The fair value of these written loan commitments was not material at March 31, 2015 and September 30, 2014, respectively. None of the noted loans were greater than 90 days past due or in nonaccrual status as of March 31, 2015 or September 30, 2014.

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 are as follows for the three and six months ended March 31, 2015 and 2014 (in thousands):

Management has determined a valuation reserve is not required for the deferred tax assets because it is more likely than not these assets could be realized through carry back to taxable income in prior years, future reversals of existing taxable temporary differences, and future taxable income.

Uncertain tax positions were not significant at March 31, 2015 or September 30, 2014.

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 2009. In July 2014, the IRS issued the final report on their examination of federal income tax returns for the periods ended September 30, 2010 and 2011.  The results of the examination did not have a material effect on our financial condition or results of operations.

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 $0.5 million and $0 to the Plan for the three months ended March 31, 2015 and 2014, respectively and $1.8 million and $1.2 million for the six months ended March 31, 2015 and 2014, respectively.

16. Stock-Based Compensation

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

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

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

Stock based compensation is recognized based on the number of awards that are ultimately expected to vest. Forfeitures are estimated based on historical turnover experience of qualified employees. For performance-based stock awards, an estimate is made of the number of shares expected to vest as a result of actual performance against the performance targets to determine the amount of compensation expense to be recognized. The estimate is reevaluated quarterly and total compensation expense is adjusted for any change in the current period. Stock-based compensation expense is included in salaries and employee benefits expense in the consolidated statements of comprehensive income. For the three months ended March 31, 2015 and 2014, stock compensation expense was $0.2 million and $0, respectively. For the six months ended March 31, 2015 and 2014, stock compensation expense was $0.7 million and $0.0 million, respectively. Related income tax benefits recognized for the three months ended March 31, 2015 and 2014 were $0.1 million and $0, respectively and $0.3 million and $0.0 million for the six months ended March 31, 2015 and 2014, respectively.

The following is a summary of the Plans’ restricted share and performance-based stock award activity as of March 31, 2015:

Restricted Shares	Common Shares		Weighted-Average Grant Date Fair Value
Restricted shares, October 1, 2014	—		$	—

The number of performance shares granted is reflected in the above table at the 100% target performance level. The actual performance-based award payouts will vary based on the achievement of the pre-established targets and can range from 0% to 150% of the target amount. The outstanding number of performance shares reflected in the table represents the number of shares expected to be awarded based on estimated achievement of the goals as of year end. However, at March 31, 2015, the maximum number of performance-based shares that could be issued if performance is attained at 150% of target based on the grants made to date was approximately 324,672 shares.

As of March 31, 2015, there was $2.5 million of unrecognized compensation cost related to nonvested restricted stock awards expected to be recognized over a period of 2.50 years.

17. Fair Value of Financial Instruments and Interest Rate Risk

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 U.S. government agency, agency mortgage-backed, states and political subdivisions, corporate debt, and other securities. Where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy.

Interest Rate Swaps and Loans

Interest rate swaps are valued using the system used to value all of NAB’s traded securities and derivatives using LIBOR rates. The fair value of loans accounted for under the fair value option represents the net carrying value of the loan, plus the equal and opposite

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

The following table presents the fair value measurements of assets and liabilities recognized in the accompanying consolidated balance sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall at March 31, 2015 and September 30, 2014 (in thousands):

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

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

Impaired Loans (Collateral Dependent)

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

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

Other Real Estate Owned (OREO)

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

Mortgage Loans Held for Sale

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

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 March 31, 2015 and September 30, 2014 (in thousands):

	Fair Value		Level 1		Level 2		Level 3

The valuation techniques and significant unobservable inputs used to measure Level 3 fair value measurements at March 31, 2015 were as follows (in thousands):

Financial Instrument	Fair Value of Assets / (Liabilities) at March 31, 2015		Valuation Technique(s)	Unobservable Input	Range	Weighted Average
Other real estate owned	$	25,162	Appraisal value	Property specific adjustment	N/A	N/A
Impaired loans	$	161,904	Appraisal value	Property specific adjustment	N/A	N/A

Fair Value of Financial Instruments

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

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

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

Notes to Consolidated Financial Statements (Unaudited)

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 March 31, 2015 and September 30, 2014, are as follows (in thousands):

		March 31, 2015				September 30, 2014

Subordinated debentures	Level 2	56,083		56,084		56,083		56,084

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

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

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

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

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

Deposits: The estimated fair value of deposits with no stated maturity, such as non-interest bearing demand deposits, savings, NOW, and money market accounts, is equal to the amount payable on demand. The fair value of interest-bearing time deposits is based on the discounted value of contractual cash flows of such deposits, taking into account the option for early withdrawal. The discount rate is estimated using the rates offered by the Company, at the respective measurement dates, for deposits of similar maturities. Deposits have been categorized as a Level 3 fair value measurement.

FHLB advances, related party notes payable, and other borrowings: The fair value of FHLB advances, related party notes payable, 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, related party notes payable, 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: The fair value of subordinated debentures is estimated using discounted cash flow analysis, based on current incremental debt rates. Subordinated debentures have been categorized as a Level 2 fair value measurement.

18. Earnings per Share

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

The following information was used in the computation of basic earnings per share (EPS) for the three and six months ended March 31, 2015 and 2014 (in thousands except share data).

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, 2014, 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, 2014.

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 March 31, 2015 and references to "the comparable period" or "the comparable quarter" refer to the fiscal quarter ended March 31, 2014.

Tax Equivalent Presentation

All references to net interest income, net interest margin, interest income on loans other than loans acquired with deteriorated credit quality, yield on loans acquired with deteriorated credit quality and the related non-GAAP adjusted measure of each item are presented on a fully-tax equivalent 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 158 branches in attractive markets in seven states: South Dakota, Iowa, Nebraska, Colorado, Arizona, Kansas and Missouri. During the quarter ended March 31, 2015, we closed three branches in Omaha, Nebraska and two branches in Sioux Falls, South Dakota. We do not believe these branch closures will have a material impact on our revenue in future periods and expect that we will achieve some cost savings in future periods as a result of the closures.

We were established more than 70 years ago and 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.

Net income was $19.7 million for the second quarter of fiscal year 2015, a decrease of $6.2 million, or 24%, compared to the second quarter of fiscal year 2014. Higher credit-related charges of $14.0 million incurred during the quarter were the primary driver of the lower net income, including provision for loan losses of $9.7 million, a $12.4 million pre-tax increase compared to the same quarter in fiscal year 2014 in which we experienced a $2.7 million release of provision for loan loan losses, and $4.3 million of other credit-related charges that impacted other financial statement line items. Increased net interest income and lower noninterest expense partially offset the increase in credit-related charges. Fiscal year-to-date net income was $46.4 million, compared to $54.6 million for the same period of fiscal year 2014.

Our efficiency ratio remained strong during the quarter at 51.7%, higher than the previous quarter due in part to fewer days in the quarter, which directly impacts our net interest income but has little offsetting impact on noninterest expense. Our efficiency ratio is 50.1% on a fiscal year-to-date basis. For more information on our efficiency ratio, including a reconciliation to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" below.

Net interest margin was 3.89%, 3.91% and 3.96%, respectively, for the quarters ended March 31, 2015, December 31, 2014, and March 31, 2014 and 3.90% and 3.99%, respectively, for the six months ended March 31, 2015 and March 31, 2014. Adjusted net interest margin, which reflects the realized gain (loss) on interest rate swaps, was 3.64%, 3.67% and 3.73%, respectively, and 3.66% and 3.77%, respectively, for the same periods. We believe our adjusted net interest margin is more representative of our underlying

- 44-

performance and is the measure we use internally to evaluate our results. Net interest margin and adjusted net interest margin declined compared to the second quarter of fiscal year 2014 primarily due to reduced asset yields. Pricing on new loans continued to be impacted by competitive pressures in the market and the continued near-zero benchmark interest rate environment, while investment portfolio yields have also declined. These reductions in asset yields were partially offset by a 4 basis point reduction in the cost of deposits over the same period, driven in part by a continued favorable change in deposit mix. 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" below.

Net income for the quarter represents earnings per common share of $0.34, compared to $0.45 in the comparable period, and is $0.80 fiscal year-to-date compared to $0.94 for the same period in fiscal year 2014. On April 28, 2015, our board of directors declared a dividend of $0.12 per common share payable on May 29, 2015 to owners of record as of the close of business on May 15, 2015.

Both loans and deposits grew during the quarter. Total loans increased $85.7 million during the quarter and from $6.79 billion at September 30, 2014 to $7.07 billion at March 31, 2015, a fiscal year-to-date increase of $285.0 million or 4.2%. Year-to-date loan growth remains balanced across the business and agriculture lending components of the portfolio including commercial non-real estate, commercial real estate and agriculture. Consistent with our expectations at the end of the first fiscal quarter, the agriculture portfolio did contract slightly during the quarter as a result of our customers' calendar year-end tax planning. The overall loan portfolio remains well diversified across a number of segments, industries and geographies. Deposits increased from $7.05 billion at September 30, 2014 to $7.49 billion at March 31, 2015, an increase of $435.5 million or 6.2%. Deposit growth during the quarter was $248.5 million. The growth during the quarter was focused within interest-bearing business and consumer transaction accounts, while noninterest-bearing transaction account and certificate of deposit balances each declined. Our deposit growth is typically focused within our first and second fiscal quarters and we do expect some seasonal deposit outflow in the third fiscal quarter driven by our customers' income tax needs and other factors.

We believe our overall asset quality remains strong, but some of our asset quality metrics declined during the quarter. At March 31, 2015, nonperforming loans were $74.3 million, with $27.8 million of the balance at March 31, 2015, covered by FDIC loss-sharing arrangements. Total nonperforming loans represent a 6% improvement compared to September 30, 2014, but have increased 9% since December 31, 2014. OREO balances have declined by $6.0 million since September 30, 2014, with $8.6 million of the $43.6 million of total OREO as of March 31, 2015 covered by FDIC loss-sharing arrangements.

Watch-rated loans increased 34% during the quarter to $384.4 million as of March 31, 2015. Some of the increase reflects ongoing proactive management of credit exposures and some of the increase resulted from a broad-based review of the loan portfolio performed in connection with the higher credit-related charges recognized during the quarter described in this quarterly report. We do not anticipate a significant negative trend in future charge-offs as a result of the increase in "Watch" loans.

Excluding charge-offs on acquired loans subject to purchase accounting fair value adjustments, net charge-offs for the second quarter of fiscal year 2015 were $9.1 million, or 0.52% of average loans on an annualized basis, bringing net charge-offs for the first six months of fiscal year 2015 to $8.1 million or 0.23% of average loans on an annualized basis. For the comparable periods in fiscal year 2014, net charge-offs were $6.2 million, or 0.39% of total loans on an annualized basis, and $5.1 million, or 0.16% of loans on an annualized basis, respectively.

Our capital position is strong and stable, with Tier 1 capital, total capital and Tier 1 leverage ratios of 11.6%, 12.6% and 9.3%, respectively, at March 31, 2015 compared to 11.8%, 12.9% and 9.1%, respectively, at December 31, 2014. The primary driver of the decrease in capital ratios was our adoption of the Basel III rules on January 1, 2015. This drove an increase in risk weighted assets of approximately $256 million, primarily related to the provisions surrounding unused lines of credit and, to a lesser extent, high-volatility commercial real estate. Our Common Equity Tier 1 ratio calculated under the new capital rules was 10.8% at March 31, 2015. Our tangible common equity to tangible assets ratio was 8.4% at March 31, 2015 compared to 8.3% at December 31, 2014. For more information on our tangible common equity to tangible assets ratio, including a reconciliation to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" below.

Until our initial public offering in October 2014 we were a wholly owned subsidiary of NAB, and our results have been part of NAB’s consolidated business operations since NAB acquired us in 2008. NAB is a large financial institution incorporated in Australia and listed on the Australian Securities Exchange with operations in Australia, New Zealand, the United Kingdom, the United States and parts of Asia. Historically, NAB and its affiliates have provided financial and administrative support to us. In connection

- 45-

with our initial public offering, we and NAB entered into certain agreements that provide a framework for our ongoing relationship, including a Stockholder Agreement governing NAB’s rights as a controlling stockholder and a Transitional Services Agreement pursuant to which NAB has agreed to continue to provide us with certain services for a transition period. Our costs associated with these services have not been significant to date and we do not expect our costs associated with these services to be significant in the future.

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, 2014, our business and results of operations are impacted by several key factors, including economic conditions, interest rates, asset quality and loss-sharing arrangements, banking laws and regulations, competition, our operational efficiency, goodwill and amortization of other intangible assets and accounting for loans and interest rate swaps at fair value.  There have been no material changes to these factors except as otherwise supplemented below and within our Quarterly Report on Form 10-Q for the three months ended December 31, 2014.

At March 31, 2015, we had $697.8 million of goodwill, $622.4 million of which relates to the acquisition of us by NAB in 2008 and was pushed down to our balance sheet, with the balance relating to subsequent acquisitions completed by us. Under relevant accounting guidance, we are required to review goodwill for impairment annually, or more frequently if events or circumstances indicate that the fair value of our business may be less than its carrying value. We determine impairment by comparing the implied fair value of the goodwill with the carrying amount of that goodwill. If the carrying amount of the goodwill exceeds the implied fair value of that goodwill, evidence of impairment is present and we will measure the impairment and potentially record an impairment loss in the amount of the excess of the carrying amount over the fair value. The valuation of goodwill is dependent on forward-looking expectations related to nationwide and local economic conditions and our associated financial performance. A significant decline in our expected future cash flows, a material change in interest rates, a significant adverse change in the business climate, slower growth rates, or a significant or sustained decline in the price of our common stock may necessitate taking charges in the future related to the impairment of our goodwill and other intangible assets.  In addition, other factors, such as a sale of our common stock by our controlling stockholder at a price below our book value per share, could negatively impact the implied fair value of our goodwill. We cannot provide assurance that we will not be required to record any charges for impairment in the future. Our recognition of any such impairment could adversely affect our business and future financial results. See “Item 1A. Risk Factors—Risks Related to Our Business—The value of our goodwill and other intangible assets may decline in the future” in our Annual Report on Form 10-K.

Our asset quality remained strong during fiscal year 2014 with continued declines in total nonperforming loans, net charge-offs and allowance for loan losses. These declines helped drive reductions in our provision for loan losses in fiscal year 2014. While our asset quality metrics remained strong through the first quarter of fiscal year 2015, we experienced higher credit-related charges in the second quarter related to a small number of C&I lending exposures and higher OREO charges. We had credit related charges of $14.0 million, including $2.6 million of net OREO charges for the three months ended March 31, 2015. This compares to $7.2 million for the three months ended December 31, 2014. The increase is primarily driven by a small number of C&I lending exposures and higher OREO charges that we believe are driven by customer-specific developments. We may have higher credit-related charges in the future.

Net interest income was $82.2 million for the second quarter of fiscal year 2015 compared to $78.1 million for the same quarter in fiscal year 2014, an increase of 5%. The increase was driven by higher interest income on loans, attributable loan growth over the previous year and more gross income related to the portion of the portfolio acquired with deteriorated credit quality, and lower deposit interest expense, partially offset by lower interest income on the investment portfolio. Compared to the same quarter in fiscal year 2014, the investment portfolio represented a smaller portion of total interest-earning assets driven by higher loan growth compared to deposit growth over the year and a higher average cash position, which was funded in part by investment portfolio run-off. Net interest margin was 3.89% for the second quarter of fiscal year 2015, compared with 3.96% for the same period in fiscal year 2014. Adjusted net interest margin was 3.64% and 3.73%, respectively, over the same periods. The lower net interest margin and adjusted net interest margin were attributable to lower asset yields, partially offset by a reduction in cost of deposits. For more

information on our adjusted net interest margin and adjusted net interest income, including a reconciliation of each to the most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" below.

Net interest income was $166.6 million for the first six months of fiscal year 2015, compared to $159.2 million for the same period in fiscal year 2014, an increase of 5%. Similar to the quarterly period, the increase was driven by higher interest income on loans and lower deposit interest expense, partially offset by lower investment portfolio interest income. Net interest margin was 3.90% for the first six months of fiscal year 2015, compared to 3.99% for the same period in fiscal year 2014, while adjusted net interest margin was 3.66% and 3.77%, respectively, for the same periods. The decreases were driven by lower asset yields and a higher average cash balance, due in part to the impact of the our largest shareholder holding our initial public offering proceeds on deposit in our bank for the majority of the first quarter of fiscal year 2015, partially offset by lower cost of deposits.

The following table presents the distribution of average assets, liabilities and equity, interest income and resulting yields on average interest-earning assets, and interest expense and rates on average interest-bearing liabilities for the current and comparable three and six month periods. Loans on nonaccrual status, totaling $74.3 million at March 31, 2015 and $91.6 million at March 31, 2014, are included in the average balances below. Any interest that had 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 $539.1 million at March 31, 2015 and $384.8 million at March 31, 2014, 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. Loans acquired with deteriorated credit quality represent loans accounted for in accordance with ASC 310-30 Accounting for Purchased Loans that were credit impaired at the time we acquired them. Loans other than loans acquired with deteriorated credit quality represent loans we have originated and loans we have acquired that were not credit impaired at the time we acquired them.

Total interest and dividend income consists primarily of interest income on loans and interest and dividend income on our investment portfolio. Total interest and dividend income was $89.8 million for the second quarter of fiscal year 2015, compared to $86.0 million for the same period of fiscal year 2014, an increase of 4%. Total interest and dividend income was $181.9 million for the first six months of fiscal year 2015, compared to $175.8 million for the same period of fiscal year 2014, an increase of 3%. Significant components of interest and dividend income are described in further detail below.

Loans. Interest income on all loans increased to $84.0 million in second quarter of fiscal year 2015 from $79.0 million in the first quarter of fiscal year 2014, an increase of 6% between the two periods. The growth was driven primarily by higher average loan balances driven by organic loan origination over the course of the year, partially offset by lower overall loan yields as a result of pricing pressure on new and renewed loans. Interest income on loans acquired with deteriorated credit quality increased $1.2 million between the two periods, primarily driven by lower amortization of the indemnification assets related to these loans in the current period as those assets related to the commercial FDIC loss-sharing arrangement are nearly fully amortized.

Interest income on all loans increased to $169.8 million in the first six months of fiscal year 2015 from $161.5 million in the same period of fiscal year 2014, an increase of 5%. Similar to the quarterly period, the growth was driven by higher average loan balances due to organic growth, partially offset by lower overall loan yields. Interest income on loans acquired with deteriorated credit

- 53-

quality increased $2.3 million between the two periods, again primarily driven by lower amortization of the indemnification assets related to these loans in the current period.

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 loans, other than loans acquired with deteriorated credit quality, was 4.86% for the second quarter of fiscal year 2015, a decrease of 23 basis points compared to 5.09% for the same period in fiscal year 2014. 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 loans, other than loans acquired with deteriorated credit quality, was 4.55% for the current quarter, a 26 basis point decrease compared to the second quarter of fiscal year 2014. The average tax equivalent yield on loans, other than loans acquired with deteriorated credit quality, was 4.91% for the first six months of fiscal year 2015, a decrease of 23 basis points compared to 5.14% for the same period in fiscal year 2014. Adjusted for the current realized gain (loss) on derivatives, the adjusted yield on loans, other than loans acquired with deteriorated credit quality, was 4.60% and 4.86%, respectively, for the same periods. These decreases continue to be attributable to the competitive interest rate environment for high quality commercial and agricultural credits across our footprint and a prolonged rate cycle with short-term rates at or near zero.

The average yield on loans acquired with deteriorated credit quality was 6.40% for the second quarter of fiscal year 2015, compared to 1.76% for the comparable period in fiscal year 2014 and 7.17% for the first six months of fiscal year 2015 compared to 2.75% for the same period in fiscal year 2014. The yield on this portion of the portfolio is heavily impacted by the amortization rates for the related FDIC indemnification assets, which we pass through interest income, and which was much higher in fiscal year 2014 as a result of overall credit-quality improvement in the acquired portfolio and the upcoming expiration of the commercial FDIC loss-sharing arrangement. While we do not expect consistent high yields on this portion of the portfolio going forward, the portfolio continues to run off and represents a very small portion of the overall loan portfolio with average balances of $131.6 million for the second quarter of fiscal year 2015 and $204.4 million for the same period of fiscal year 2014, 2% and 3% of the total average loan portfolio, respectively.

Average net loan balances for the second quarter of fiscal year 2015 were $6.96 billion, representing an 8% increase compared to the same period in fiscal year 2014. The growth was focused in the CRE, commercial non-real estate ("C&I") and agribusiness segments of the portfolio.

Loan-related fee income of $2.3 million is included in interest income for the second quarter of fiscal year 2015 compared to $1.8 million for the same period in fiscal year 2014. Loan-related fee income was $4.5 million for the first six months of fiscal year 2015 compared to $3.9 million for the same period of fiscal year 2014. 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 $2.1 million and $4.7 million for the second quarter of fiscal years 2015 and 2014, respectively, and $4.6 million and $7.9 million for the first six months of fiscal years 2015 and 2014, respectively, is included as a reduction to interest income.

Investment Portfolio. Interest and dividend income on investments includes income earned on investment securities and FHLB stock. During the second quarter of fiscal year 2015, the balance of our investment portfolio increased by $138.5 million, or 11%, to $1.40 billion. The increase was driven by investment purchases made during the quarter as a result of strong deposit growth and excess liquidity invested to earn additional interest income. Interest and dividend income on investments decreased from $6.8 million in the second quarter of fiscal year 2014 to $5.7 million in the second quarter of fiscal year 2015, a decrease of 17%, driven both by lower average balances in the portfolio and a reduction in yield from 2.01% in the second quarter of fiscal year 2014 to 1.72% for the same period in fiscal year 2015. Interest and dividend income on investments decreased from $14.0 million in the first six months of fiscal year 2014 to $11.6 million for the same period in fiscal year 2015, also a decrease of 17%, driven both by lower average balances in the portfolio and a reduction in yield from 1.97% to 1.74% over the same period.

The weighted average life of the portfolio was 2.9 years and 3.1 years at March 31, 2015 and September 30, 2014, respectively. Average investments represented 16% and 17% of total average interest-earning assets in the second quarter of fiscal years 2015 and 2014, respectively, and 16% and 18% for the first six months of fiscal years 2015 and 2014, respectively. The carrying value of investment securities and FHLB stock was $1.43 billion as of March 31, 2015.

Total interest expense consists primarily of interest expense on five components of our balance sheet: deposits, securities sold under agreements to repurchase, FHLB advances and other borrowings, related party notes payable and our outstanding subordinated debentures. Total interest expense decreased to $7.6 million in the second quarter of fiscal year 2015 from $7.9 million for the same quarter in fiscal year 2014, a decrease of 4%, despite an increase in average interest-bearing liabilities from $7.68 billion to $8.11 billion over the same period, driven primarily by lower cost of deposits and lower average cost of FHLB advances. The average cost of total interest-bearing liabilities was 0.38% for the second quarter of fiscal year 2015, compared to 0.42% for the same period in fiscal year 2014. Total interest expense was $15.2 million for the first six months of fiscal year 2015, a decrease of 8% compared to $16.6 million for the same period in fiscal year 2014. The average cost of total interest-bearing liabilities was 0.38% for the first six months of fiscal year 2015, compared to 0.43% for the same period in fiscal year 2014. Significant components of interest expense are described in further detail below.

Deposits. Interest expense on deposits, consisting of checking accounts, MMDAs, NOW accounts, savings accounts and CDs, was $6.0 million in the second quarter of fiscal year 2015 compared with $6.4 million in the second quarter of fiscal year 2014, a decrease of $0.4 million, or 7%. Average deposit balances were $7.30 billion and $7.13 billion, respectively, for the same periods. The average rate declined from 0.37% for the second quarter of fiscal year 2014 to 0.33% for the same period in fiscal year 2015.

Interest expense on deposits was $12.0 million for the first six months of fiscal year 2015, a reduction of $1.3 million, or 10%, compared to the same period in fiscal year 2014. Average deposit balances were $7.31 billion and $7.12 billion, respectively, and the average rate declined from 0.38% to 0.33%, respectively, for the same periods.

Average non-interest-bearing demand account balances comprised 19% of average total deposits for the current quarter, compared with 18% for the comparable quarter. Total average other liquid accounts, consisting of money market and savings accounts, continued to increase to 59% of total average deposits for the current quarter, compared to 55% of total average deposits for the

comparable quarter, while CD accounts represented 22% of average total deposits in the current quarter, compared to 27% in the comparable quarter. These trends in the composition of our deposit portfolio represent a continuation of our strategy over the last three fiscal years to move away from more costly CD accounts toward more cost-effective transaction accounts as well as our focus on gathering business deposits, which are typically transaction accounts by nature. This transition, as well as continued low benchmark interest rates, have driven a significant decrease in our cost of deposits over that time frame.

FHLB Advances and Other Borrowings. Interest expense on FHLB advances and other borrowings was $0.9 million for the second quarter of fiscal year 2015, compared to $0.8 million for the same period in fiscal year 2014, reflecting weighted average cost of 0.69% and 1.26%, respectively. Our average balance for FHLB advances and other borrowings increased to $528.6 million in the current quarter compared to $259.1 million in the comparable quarter. Interest expense on FHLB advances and other borrowings was $1.8 million for the first half of fiscal year 2015 and for the first half of fiscal year 2014, representing a weighted average cost of 0.67% and 1.19%, respectively. The amount of FHLB advances outstanding has increased over the past 12 months to fund a portion of the strong loan growth we have achieved, which has outpaced deposit growth over the same period, despite the fact that we repaid $100 million of FHLB advances in the current quarter. Average FHLB advances and other borrowings as a proportion of total average interest-bearing liabilities were 7% for the current quarter compared to 4% for the comparable quarter. The average rate paid on FHLB advances is impacted by market rates and the various terms and repricing frequency of the specific outstanding borrowings in each year. Our total outstanding FHLB advances were $475.0 million at March 31, 2015 compared to $575.0 million at December 31, 2014 and September 30, 2014. The weighted average contractual rate paid on our FHLB advances was 0.71% at March 31, 2015 and 0.62% at September 30, 2014. The average tenor of our FHLB advances was 47 months and 56 months at March 31, 2015 and September 30, 2014, respectively. The amount of other borrowings and related interest expense as of and for the current quarter were immaterial.

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 March 31, 2015, we had pledged $2.2 billion of loans to the FHLB, against which we had borrowed $475.0 million.

Subordinated Debentures and Other. Interest expense on our outstanding subordinated debentures was $0.3 million in both the current and comparable quarters and $0.7 million in the first six months of both the current and prior fiscal years. At March 31, 2015 and September 30, 2014, the weighted average contractual rate on outstanding subordinated notes was 2.29%.

Securities Sold Under Agreements to Repurchase; Related Party Notes Payable. Securities sold under agreements to repurchase represent retail repurchase agreements with customers and, together, with our related party notes payable, represent a small portion of our overall funding profile. The interest expense associated with these two classes 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 tables present the current and comparable quarter and the first six months of the current and prior fiscal year and a summary of the changes in interest income and interest expense resulting from changes in the volume of average asset and liability balances and changes in the average yields or rates compared with the preceding fiscal year. If significant, the change in interest income or interest expense due to both volume and rate has been prorated between the volume and the rate variances based on the dollar amount of each variance. The table illustrates the continued benefit of balance sheet growth, mainly within loans funded by cost-effective deposit growth, partially offset by a reduction in net interest margin most pronounced in loan yield.

Provision for Loan Losses

We recognized provision for loan losses of $9.7 million for the second quarter of fiscal year 2015 compared to a release of provision for loan losses of $2.7 million for the comparable period in fiscal year 2014, an increase of $12.4 million between the two periods. This change was driven by an increase in a specific allowance required for a small number of primarily C&I loan exposures that deteriorated during the quarter, and to a lesser extent, an increase in loan growth and the effect on the allowance of recording higher net charge-offs during the current quarter compared to recent quarters. Provision for loan losses was $13.0 million for the first six months of fiscal year 2015 compared to a release of provision for loan losses of $3.6 million for the same period in fiscal year 2014, an increase of $16.6 million. The table below outlines the components of provision for loan losses in each period presented. All loans acquired with deteriorated credit quality for which we recognized improvements or impairments in the periods presented are covered by FDIC loss-sharing arrangements. We did not record any meaningful provision for loans covered by FDIC loss-sharing arrangements related to loans other than loans acquired with deteriorated credit quality in any of the periods presented.

Total Credit-Related Charges

In addition to the higher provision for loan losses we incurred during the current fiscal quarter compared to the same quarter in fiscal year 2014, we recognized other credit-related charges during the quarter, as discussed elsewhere within this quarterly report. We believe that the following table, which summarizes each component of the total credit-related charges incurred during the current, prior and comparable quarters, is helpful to understanding the overall impact on our quarterly results of operations. Net OREO charges include OREO operating costs, valuation adjustments and gain (loss) on sale of OREO properties, each of which entered OREO as a result of the former borrower failing to perform on a loan obligation. Reversal of interest income on nonaccrual loans occurs when we become aware that a loan, for which we had been recognizing interest income, will no longer be able to perform according to the terms and conditions of the loan agreement, including repayment of interest owed to us. 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.

Subtotal, loans at fair value and related derivatives	(13,995		)	(7,979		)
Total noninterest income	$	14,836		$	20,966

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 US 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 $6.9 million for the second quarter of fiscal year 2015, compared to $10.1 million for the comparable period in fiscal year 2014, a decrease of 32%, and $14.8 million for the first six months of fiscal year 2015, compared to $21.0 million for the same period in fiscal year 2014, a decrease of 29%.

- 59-

Product and Service Fees. We recognized $13.4 million of noninterest income related to product and service fees in the second quarter of fiscal year 2015, a decrease of $0.4 million, or 3%, compared to the same period in fiscal year 2014. Net gain on sale of loans, which represents the fees we earn originating and selling home mortgages into the secondary market, increased $0.6 million between the two periods, while service charges and other fees (primarily deposit account OD and NSF fees) and other noninterest income each declined by $0.5 million. The impact in other noninterest income primarily represents a decrease in the portion of recoveries related to loans we acquired in a charged-off status we are entitled to retain.

Noninterest income related to product and services fees was $28.8 million for the first six months of fiscal year 2015 compared to $28.9 million for the same period in fiscal year 2014. Net gain on sale of loans increased $0.6 million, driven by higher mortgage origination volumes, while service charges and other fees decreased by $0.8 million. We believe the decrease in deposit account service charges and fees is representative of changing customer behavior and a shift in mix toward more business deposit accounts, which typically carry higher average balances but incur fewer fees on a relative basis.

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 second quarter of fiscal year 2015, these items accounted for $(6.5) million of noninterest income compared to $(3.7) million for the same period in fiscal year 2014. The change was driven by a $1.9 million difference in the changes in fair value of the loans related to credit risk and a $0.9 million increase in the realized loss on the derivatives driven primarily by volume growth. For the first six months of fiscal year 2015, these items accounted for $(14.0) million of noninterest income compared to $(8.0) million for the same period of fiscal year 2014. The change was driven by a $4.1 million difference in the changes in fair value of the loans related to credit risk and a $1.9 million increase in the realized loss on the derivatives driven primarily by volume growth. 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.

Other	11,854			11,023
Total noninterest expense	$	95,529		$	97,626

Our noninterest expense consists primarily of salaries and employee benefits, net occupancy expenses, data processing, professional fees and amortization of core deposits and other intangibles. Noninterest expense was $48.4 million in the second quarter of fiscal year 2015 compared to $49.3 million for the same period in fiscal year 2014, a decrease of 2% or $0.9 million. Adjusted for the amortization of intangible assets, our tangible noninterest expenses were $46.1 million in the second quarter of fiscal year 2015, a 3% increase over the same period in fiscal year 2014. Our efficiency ratio was 51.7% for the current quarter and 50.6% for the comparable quarter. Noninterest expense was $95.5 million in the first six months of fiscal year 2015 compared to $97.6 million for the same period in fiscal year 2014, a decrease of 2% or $2.1 million. Adjusted for the amortization of intangible assets, our tangible noninterest expenses were $90.9 million in the first six months of fiscal year 2015, a 3% increase over the same period in fiscal year 2014. Our efficiency ratio was 50.1% and 49.0%, respectively, for the same periods. For more information on our tangible noninterest expense and efficiency ratio, including a reconciliation of each to the most directly comparable GAAP financial measures, see "—Non-GAAP Financial Measures" below.

- 61-

The quarterly increase in tangible noninterest expenses compared to the second quarter of fiscal year 2014 was primarily driven by a $1.6 million increase in salaries and employee benefits, primarily related to favorable nonrecurring events in the comparable period, and a $0.5 million increase in professional fees, including audit and insurance costs related to being a public company which we expect to continue going forward, partially offset by a $0.5 million decrease in net occupancy costs driven by cost savings generated by branch closures completed in previous fiscal years. On a fiscal year-to-date basis, the increase in tangible noninterest expense was also driven by higher salaries and employee benefits and professional fees, partially offset by lower occupancy costs and advertising. Although not included in tangible noninterest expense, amortization of core deposits and other intangibles also decreased substantially between the two periods, driven entirely by lower scheduled amortization as these assets continue to be amortized.

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 $9.7 million for the second quarter of fiscal year 2015 represents an effective tax rate of 33.0%, compared to provision of $14.5 million or an effective tax rate of 35.8% for the comparable period. The provision for income taxes of $23.4 million for the first six months of fiscal year 2015 represents an effective tax rate of 33.5% compared to an effective tax rate of 35.0% for the same period in fiscal year 2014. In each case, the decrease in rate is primarily due to a larger amount of tax exempt interest and the mix of state and local taxes we recognized. We have historically calculated our provision for income taxes as though we were a standalone company and we do not expect any material changes in our provisioning for income taxes as a result of our initial public offering.

During the second quarter of fiscal year 2015, total loans grew by 1.2%, or $85.7 million. The growth was primarily focused in the CRE,C&I, and agriculture segments of the portfolio. Over the same time period, residential real estate, consumer and other loan balances remained generally stable.

The following table presents an analysis of the unpaid principal balance of our loan portfolio at March 31, 2015, by borrower and collateral type and by each of the four major geographic areas we use to manage our markets.

Commercial Non-Real Estate. Commercial non-real estate, or business lending, represents one of our core competencies. We believe that providing a tailored range of integrated products and services, including lending, to small- and medium-enterprise customers is the business at which we excel and through which we can generate favorable returns for our stockholders. We offer a number of different products including working capital and other shorter-term lines of credit, fixed-rate loans over a wide range of terms including our tailored business loans, for which we enter into matching interest rate swaps that give us floating payments for all deals over five years, and variable-rate loans with varying terms.

Agriculture. Agriculture loans include farm operating loans and loans collateralized by farm land. According to the American Bankers Association, at December 31, 2014, we were ranked the seventh-largest farm lender bank in the United States measured by total dollar volume of farm loans, and we take great pride in our knowledge of the agricultural industry across our footprint. We consider agriculture lending one of our core competencies. In 2008, agriculture loans comprised approximately 15% of our overall loan portfolio, compared to 25% as of March 31, 2015. 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.

Commercial Real Estate. CRE includes both owner-occupied CRE and non-owner-occupied CRE and construction and development lending. While CRE lending will remain a significant component of our overall loan portfolio, we are committed to managing our exposure to riskier construction and development deals specifically, and to CRE lending in general, by targeting relationships with relatively low loan-to-value positions, priced to reflect the amount of risk we accept as the lender. This focus on rebalancing the portfolio is reflected in the fact that CRE lending comprised nearly 50% of the portfolio at the time of the NAB acquisition in 2008, compared to 38% as of March 31, 2015.

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 cannot subsequently sell into the secondary market, including 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 and customer deposit account overdrafts.

OREO

In the normal course of business, we obtain title to parcels of real estate and other assets when borrowers are unable to meet their contractual obligations and we initiate foreclosure proceedings, or via deed in lieu of foreclosure actions. OREO assets are considered nonperforming assets. When we obtain title to an asset, we evaluate how best to maintain and protect our interest in the property and seek to liquidate the assets at an acceptable price in a timely manner. Our total OREO carrying value was $43.6 million as of March 31, 2015, a decrease of $0.1 million and $6.0 million compared to December 31, 2014 and September 30, 2014, respectively. The amount of OREO covered by FDIC loss-sharing arrangements was $8.6 million as of March 31, 2015 and $10.6 million as of September 30, 2014. The following table presents our OREO balances for the period indicated:

We have historically invested excess deposits in high-quality, liquid investment securities including residential agency mortgage-backed securities and, to a lesser extent, U.S. Treasury securities, corporate debt securities and securities issued by U.S. states and political subdivisions. Our investment portfolio serves as a means to collateralize FHLB borrowings and public funds deposits, to earn net spread income on excess deposits and to maintain liquidity and balance interest rate risk. Dating to the beginning of fiscal year 2011, the portfolio composition was heavily weighted toward Government National Mortgage Association ("GNMA") residential agency mortgage-backed securities to fit the risk appetite and financial return targets of NAB; however, we rebalanced approximately $100 million of the portfolio into non-GNMA mortgage-backed securities in the second quarter of fiscal year 2015 to balance our interest rate risk exposures. U.S. Treasury securities comprised 20% of the total market value of the portfolio as of March 31, 2015. Since September 30, 2014, the carrying value of the portfolio has increased by $61.3 million, or 4.5%.

The following tables present the aggregate amortized cost of each investment category of the investment portfolio and the weighted average yield for each investment category for each maturity period at March 31, 2015. Maturities of mortgage-backed securities may differ from contractual maturities because the mortgages underlying the securities may be called or prepaid without any penalties. The weighted-average yield on these assets is presented below based on the contractual rate, as opposed to a tax equivalent yield concept.

Asset Quality

We place an asset on nonaccrual status when any installment of principal or interest is more than 90 days past due (except for loans that are well secured and in the process of collection) or earlier when management determines the ultimate collection of all contractually due principal or interest to be unlikely. Restructured loans for which we grant payment or significant interest rate concessions are placed on nonaccrual status until collectability improves and a satisfactory payment history is established, generally

- 68-

by the receipt of at least six consecutive payments. Our collection policies related to delinquent and charged-off loans are highly focused on individual relationships, and we believe that these policies are in compliance with all applicable laws and regulations.

The following table presents the dollar amount of nonaccrual loans, OREO, restructured performing loans and accruing loans over 90 days past due, at the end of the dates indicated. Loans covered by FDIC loss-sharing arrangements are generally pooled with other similar loans and are generally accreting purchase discount into income each period. Subject to compliance with the applicable loss-sharing agreement, we are generally indemnified by the FDIC at a rate of 80% for any future credit losses on loans covered by FDIC loss-sharing arrangements through June 4, 2015 for commercial loans and June 4, 2020 for single-family real estate loans.

At March 31, 2015, our nonperforming assets were 1.21% of total assets, compared to 1.37% at September 30, 2014.

Excluding loans covered by FDIC loss-sharing arrangements, we had average nonaccrual loans (calculated as a two-point average) of $45.2 million outstanding during the first six months of fiscal year 2015. Based on the average loan portfolio yield for these loans for the quarter, we estimate that interest income would have been less than $1 million higher during the quarter had these loans been accruing. During the same period, the amount of net interest income that we recorded on these loans was immaterial.

Nonaccrual loans not covered by FDIC loss-sharing arrangements increased by $2.6 million compared to September 30, 2014, and by $7.5 million compared to December 31, 2014. Since September 30, 2014, C&I nonaccrual loans have increased by $4.1 million, driven primarily by deterioration of four specific relationships that triggered the majority of the increased credit-related charges in the current quarter, agriculture nonaccrual loans have increased $7.4 million, primarily driven by the deterioration of three specific relationships, and CRE nonaccrual loans have decreased $9.9 million, primarily driven by the liquidation of one customer's business, which triggered a partial charge-off in the first fiscal quarter.

Nonaccrual loans covered by FDIC loss-sharing arrangements continued to decline and are down $7.1 million since September 30, 2014, and we expect these loans to continue to decline due to the expiration of the commercial loss-sharing arrangement on June 4, 2015 and the natural runoff through payment or foreclosure of the underlying assets.

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

As noted previously, "watch" rated loans increased 34% between December 31, 2014 and March 31, 2015. During the same time period, "substandard" and "doubtful" loans have also increased. Total past due loans have decreased during that time period. Some of the increase in "watch" loans reflects proactive management of potential credit exposures resulting from a broad-based review of our loan portfolio in conjunction with the credit-related charges described in this quarterly report, while some of the increase is seasonal in nature and representative of normal business cycles. We do not anticipate a significant negative trend in future charge-offs as a result of the increase in "watch" or "substandard" loans.

When we grant concessions to borrowers that we would not otherwise grant if not for the borrowers’ financial difficulties, such as reduced interest rates or extensions of loan periods, we consider these modifications troubled debt restructurings, or TDRs. The table below outlines total TDRs, split between performing and nonperforming loans, at each of the dates indicated:

We entered into loss-sharing arrangements with the FDIC related to certain assets (loans and OREO) 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, 2015 for commercial loans and OREO and June 4, 2020 for single-family real estate loans and OREO.

Allowance for Loan Losses

We establish an allowance for the inherent risk of probable losses within our loan portfolio. The allowance for loan losses is management’s best estimate of probable credit losses that are incurred in the loan portfolio. We determine the allowance for loan 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 losses are made by charges to the provision for loan losses. Loans deemed to be uncollectible are charged off against the allowance for loan losses. Recoveries of amounts previously charged-off are credited to the allowance for loan losses.

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

In the first six months of fiscal year 2015, we recorded net charge-offs of $8.1 million, representing 0.23% of average total loans on an annualized basis, a 9 basis point increase compared to 0.14% for fiscal year 2014. The charge-offs we recorded during the first six months were primarily related to a small number of loans in the C&I portfolio.

At March 31, 2015, the allowance for loan losses was 0.74% of our total loan portfolio, a 4 basis point increase compared with 0.70% at September 30, 2014. The provision recorded during the quarter was predominantly driven by a small number of C&I relationships that deteriorated during the quarter.

Additionally, certain of our loans which are carried at fair value, totaling $1.06 billion and $985 million at March 31, 2015 and September 30, 2014, respectively, have no associated allowance for loan losses, but rather have a fair value adjustment related to credit risk, which is reflected in noninterest income, thus driving the overall ratio of allowance for loan losses to total loans lower. The amount of fair value adjustment related to credit risk on these loans was $5.5 million and $6.0 million at March 31, 2015 and September 30, 2014, respectively.

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

	March 31, 2015		September 30, 2014

Residential real estate	14.3	%	17.6	%
Consumer	0.4	%	0.6	%
Other lending	1.6	%	1.7	%

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

The review of problem loans is an ongoing process during which management may determine that additional charge-offs are required or additional loans should be placed on nonaccrual status. We recorded provision for loan losses of $9.7 million during the second quarter of fiscal year 2015. 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 $0.4 million at March 31, 2015 and September 30, 2014.

Deposits

We obtain funds from depositors by offering consumer and business demand deposit accounts, MMDAs, NOW accounts, savings accounts and term CDs. At March 31, 2015 and September 30, 2014, our total deposits were $7.49 billion and $7.05 billion, respectively, an increase of 6.1%. Our accounts are federally insured by the FDIC up to the legal maximum. We advertise in newspapers, on the Internet and on television and radio to attract deposits and perform limited direct telephone solicitation of potential institutional depositors such as investment managers, public depositors and pension plans. We have significantly shifted the composition of our deposit portfolio away from CDs toward demand, NOW, MMDA and savings accounts over the last 27 months. This has dramatically reduced our overall cost of deposit funding, in addition to the fact that we have greatly increased adherence to internally published rate offerings for various types of deposit account offerings. The following table presents the balances and weighted average cost of our deposit portfolio at the following dates:

	March 31, 2015				September 30, 2014
	Amount		Weighted Avg. Cost		Amount		Weighted Avg. Cost

Municipal public deposits constituted $1.05 billion and $1.00 billion of our deposit portfolio at March 31, 2015, and September 30, 2014, respectively, of which $764 million and $760 million, respectively, were required to be collateralized. Our top 10 depositors were responsible for 10% and 9% of our total deposits at March 31, 2015 and September 30, 2014, respectively.

We fund a portion of our assets with CDs that have balances of $100,000 or more and that have maturities generally in excess of six months. At March 31, 2015 and September 30, 2014, our CDs of $100,000 or more totaled $632 million and $733 million, respectively. The following table presents the maturities of our CDs of $100,000 or more and less than $100,000 in size at March 31, 2015:

Derivatives

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

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:

Great Western also has a $10 million revolving line of credit issued by NAB that is due on demand. Amounts outstanding under the line of credit bear interest at a rate equal to the London inter-bank offered rate, or LIBOR, for three-month U.S. dollar deposits plus 125 basis points, with interest payable quarterly. The interest rate is recalculated every quarter and was 1.52% at March 31, 2015. There were outstanding advances of $5.5 million on this line of credit at each of March 31, 2015 and September 30, 2014. We incurred an immaterial amount of interest expense related to this facility during the quarter.

Other Borrowings

Great Western has outstanding $56.1 million of junior subordinated debentures to affiliated trusts in connection with the issuance of trust preferred securities by such trusts as of March 31, 2015 and September 30, 2014. We are permitted under applicable laws and regulations to count these trust preferred securities as part of our Tier 1 capital.

Great Western also has outstanding a subordinated capital note issued to NAB New York Branch having an aggregate principal amount of approximately $35.8 million maturing in June 2018. Interest on the note is payable quarterly and accrues at a rate equal to LIBOR for three-month U.S. dollar deposits plus 205 basis points. The interest rate on the note is recalculated every quarter and was 2.32% at March 31, 2015. We incurred $0.2 million in interest expense on the outstanding note during the quarter. Subject to receipt of regulatory approval, we may prepay the note at any time, in whole but not in part, without penalty.

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:

	March 31, 2015		September 30, 2014

Commitments to extend credit	$	1,906,057	$	1,939,544

Liquidity

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

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

Great Western. Great Western’s primary source of liquidity is cash obtained from dividends 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 related party notes payable. We also use cash, as necessary, to satisfy the needs of our bank through equity contributions and for acquisitions. At March 31, 2015, Great Western had $12.8 million of cash. During the second quarter of fiscal year 2015, we declared and paid a dividend of $0.12 per share. The outstanding amounts under our revolving line of credit with NAB and subordinated capital note issued to NAB New York Branch together totaled $41.3 million at March 31, 2015. Our management believes that the sources of available liquidity are adequate to meet all reasonably foreseeable short-term and intermediate-term demands.

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 March 31, 2015, our bank had cash of $358.4 million and $1.4 billion of highly-liquid securities held in our investment portfolio, of which $1.05 billion were pledged as collateral on public deposits, securities sold under agreements to repurchase, and for other purposes as required or permitted by law. The balance could be sold to meet liquidity requirements. Our bank also had $475.0 million in FHLB borrowings at March 31, 2015, with additional available lines of $796 million. Our bank primarily uses liquidity to meet loan requests and commitments (including commitments under letters of credit), to accommodate outflows in deposits and to take advantage of interest rate market opportunities. At March 31, 2015, we had a total of $1.96 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 March 31, 2015 and the standards for both well-capitalized depository institutions and minimum capital requirements. Our capital ratios exceeded applicable regulatory requirements.

Common equity Tier 1	853,175		11.9	%	4.5	%	6.5	%
Risk-weighted assets	7,181,246

At March 31, 2015 and September 30, 2014, our Tier 1 capital included an aggregate of $56.1 million of trust preferred securities issued by our subsidiaries. At March 31, 2015, our Tier 2 capital included $52.4 million of the allowance for loan losses and $21.5 million of an intercompany subordinated capital note, subject to phase-out and a current haircut of 60%. At September 30, 2014, our Tier 2 capital included $47.5 million of the allowance for loan losses and $21.5 million of an intercompany subordinated capital note, subject to phase-out and a current haircut of 60%. Our total risk-weighted assets were $7.19 billion at March 31, 2015.

In July 2013, the federal bank regulators approved capital rules implementing the Basel III capital framework and various provisions of the Dodd-Frank Act (the "New Capital Rules"). Effective January 1, 2015, we and our bank adopted these rules, subject to the phase-in of certain provisions. In addition to other changes, the New Capital Rules established a new common equity Tier 1 capital ratio.

Non-GAAP Financial Measures

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

In particular, we evaluate our profitability and performance based on our cash net income and return on average tangible common equity, each of which excludes 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 based on our cash payments and receipts during the applicable period.

We also evaluate our profitability and performance based on our adjusted net interest income, adjusted net interest margin, adjusted interest income on loans other than loans acquired with deteriorated credit quality and adjusted yield on loans other than

- 81-

loans acquired with deteriorated credit quality. 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. 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.

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

Internal Control Over Financial Reporting

Until our initial public offering in October 2014, we were a wholly owned subsidiary of NAB, and our results have been included in NAB’s consolidated financial statements since NAB acquired us in 2008. As a result, we have historically reported our

- 83-

financial results to NAB under International Financial Reporting Standards (“IFRS”), which were applicable to us as a wholly owned subsidiary of NAB. In accordance with the terms of the Stockholder Agreement we entered into with NAB, we are required to report our financial results to NAB under IFRS until such time as NAB is no longer required under IFRS to account in its financial statements for its holdings in our business under an equity method of accounting (unless our obligation is terminated earlier by NAB). In addition, as regulated financial institutions, we and our bank have also reported our financial results under GAAP for an extended period of time, as required under the financial reporting regulatory regime applicable to financial institutions and their holding companies in the U.S. We are required to report financial results under GAAP to the Federal Reserve, and our bank is also required to report financial results under GAAP to the FDIC and the South Dakota Division of Banking.

As a publicly traded company, we are subject to the financial reporting standards prescribed under GAAP and SEC rules, which are more extensive than the standards applicable to us as a wholly owned subsidiary of NAB prior to our initial public offering. Complying with these heightened financial reporting standards has required us to implement enhancements to the design and operation of our internal control over financial reporting. In the process of preparing additional disclosures required by the SEC for public companies contained within our consolidated financial statements under these requirements in connection with our initial public offering, during the third quarter of fiscal year 2014, we concluded a material weakness existed in the design and operation of our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected on a timely basis. The material weakness identified resulted primarily from a lack of sufficient resources and personnel within the accounting function engaged in the preparation and review of our consolidated financial statements and a lack of formal controls and procedures with respect to our internal review of the accuracy and completeness of our application of SEC rules to our consolidated financial statements. The material weakness did not affect our reported net income or stockholders' equity for any financial reporting period or materially affect our reported total assets and total liabilities for any financial reporting period.

Following identification of the material weakness, we implemented a number of controls and procedures designed to improve our control environment. In particular, we included additional members of our accounting and financial reporting staff in the preparation and review of the consolidated financial statements for the year ended September 30, 2014 and the quarters ended March 31, 2015 and December 31, 2014, respectively, and have implemented a more formal preparation and review hierarchy designed to identify and resolve potential errors on a timely basis. We have also contracted with two independent consulting firms to assist us in the preparation of our consolidated financial statements. In addition, within our financial reporting function, we have hired additional personnel with SEC publicly traded company reporting experience to assist with the preparation and review of future financial statements and have allocated a greater number of our employees to assist with these processes. Specifically, in March 2015, we hired additional experienced, qualified personnel within our financial reporting function to assist with the preparation and review of future financial statements.

Although we believe these changes to our control environment will be sufficient to remediate our previously identified material weakness, we believe that further reporting periods are required to confirm the remediation as well as the ongoing effectiveness of the revised control environment. We may be unsuccessful in implementing all remedial measures we may undertake, and these measures may not significantly improve or remediate the material weakness identified in the design and operating effectiveness of our internal control over financial reporting, which, in future periods, could impact our ability to report our financial results accurately or on a timely basis. As a result of the material weakness, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of September 30, 2014.

More generally, if we are unable to meet the demands that have been placed upon us as a public company, including the requirements of Sarbanes-Oxley, we may be unable to accurately report our financial results in future periods, or report them within the timeframes required by law or stock exchange regulations. Failure to comply with Sarbanes-Oxley, when and as applicable, could also potentially subject us to sanctions or investigations by the SEC or other regulatory authorities. Under such circumstances, we may be unable to implement the necessary internal controls in a timely manner, or at all, and future material weaknesses may exist or may be discovered. If we fail to implement the necessary improvements, or if material weaknesses or other deficiencies occur, our ability to accurately and timely report our financial position could be impaired, which could result in late filings of our annual and quarterly reports under the Exchange Act, restatements of our consolidated financial statements, a decline in our stock price, suspension or delisting of our common stock from the NYSE and could have a material adverse effect on our business, results of operations or financial condition. Even if we are able to report our financial statements accurately and in a timely manner, any failure in our efforts to implement the improvements or disclosure of material weaknesses in our future filings with the SEC could cause our reputation to be harmed and our stock price to decline significantly.

- 84-

We have not performed an evaluation of our internal control over financial reporting, as contemplated by Section 404 of Sarbanes-Oxley, nor have we engaged our independent registered public accounting firm to perform an audit of our internal control over financial reporting as of any balance sheet date reported in our financial statements. Had we performed such an evaluation or had our independent registered public accounting firm performed an audit of our internal control over financial reporting, additional control deficiencies, including additional material weaknesses and significant deficiencies, may have been identified. In addition, the JOBS Act provides that, so long as we qualify as an “emerging growth company,” we will be exempt from the provisions of Section 404(b) of Sarbanes-Oxley, which would require that our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting. We may take advantage of this exemption so long as we qualify as an “emerging growth company.”

Impact of Inflation and Changing Prices

Our financial statements included in this prospectus 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.

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, 2014.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of March 31, 2015, 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, 2014.

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 March 31, 2015 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

- 85-

and gradual shifts upward of 100, 200, 300 and 400 basis points over 12 months. In the current interest rate environment, a downward shift of the yield curve of 200, 300 and 400 basis points does not provide us with meaningful results. In a downward parallel shift of the yield curve, interest rates at the short-end of the yield curve are not modeled to decline any further than 0%. For the immediate-shift scenarios, we assume short-term rates follow a forward yield curve throughout the forecast period that is dictated by the instantaneously shocked yield curve from the as of date. In the gradual-shift scenarios, we take each rate across the yield curve from the as of date and shock it by 1/12th of the total change in rates each month for twelve months.

	Estimated Increase (Decrease) in Annualized Adjusted Net Interest Income for the Quarter Ended March 31, 2015
Change in Market Interest Rates as of March 31, 2015	Twelve Months Ending March 31, 2016		Twelve Months Ending March 31, 2017
Immediate Shifts
+400 basis points	16.94	%	9.85	%
+300 basis points	12.84	%	7.61	%
+200 basis points	8.60	%	5.24	%
+100 basis points	4.29	%	2.79	%
-100 basis points	(2.73	)%	(2.66	)%
Gradual Shifts
+400 basis points	2.21	%
+300 basis points	1.41	%
+200 basis points	0.68	%
+100 basis points	0.12	%
-100 basis points	0.91	%

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.

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

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures.    We maintain disclosure controls and procedures, as defined in Rule 13a−15(e) promulgated under the Exchange Act, that are designed to ensure that information required to be disclosed by us in the 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 our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

- 86-

In connection with the filing of this Quarterly Report on Form 10-Q, an evaluation was carried out by our management, with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures. Our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of March 31, 2015 due to the material weakness in our internal control over financial reporting described in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations-Internal Control Over Financial Reporting.” 

(b) Changes in Internal Controls over Financial Reporting.    This Quarterly Report on Form 10-Q does not include a report on changes in our internal controls over financial reporting that occurred during our most recent fiscal quarter due to a transition period established by the Exchange Act for new reporting companies.  Following identification of the material weakness referenced above, we implemented a number of controls and procedures designed to improve our control environment as described in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations-Internal Control Over Financial Reporting.”

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

There have been no material changes in legal proceedings as described in our Annual Report on Form 10-K for the fiscal year ended September 30, 2014.

ITEM 1A. RISK FACTORS

During the quarter, the following additions below were made to the risk factors described in our Annual Report on Form 10-K for the fiscal year ended September 30, 2014.

The operation of our business requires us to manage credit risk. As a lender, we are exposed to the risk that our borrowers will be unable to repay their loans according to their terms, and that the collateral securing repayment of their loans, if any, may not be sufficient to ensure repayment. In addition, there are risks inherent in making any loan, including risks with respect to the period of time over which the loan may be repaid, risks relating to proper loan underwriting, risks resulting from changes in economic and industry conditions and risks inherent in dealing with individual borrowers, including the risk that a borrower may not provide information to us about its business in a timely manner, and/or may present inaccurate or incomplete information to us, and risks relating to the value of collateral. In order to successfully manage credit risk, we must, among other things, maintain disciplined and prudent underwriting standards and ensure that our bankers follow those standards. The weakening of these standards for any reason, such as an attempt to attract higher yielding loans, a lack of discipline or diligence by our employees in underwriting and monitoring loans, the inability of our employees to adequately adapt policies and procedures to changes in economic or any other conditions affecting borrowers and the quality of our loan portfolio, may result in loan defaults, foreclosures and additional charge-offs and may necessitate that we significantly increase our allowance for loan losses, each of which could adversely affect our net income. As a result, our inability to successfully manage credit risk could have a material adverse effect on our business, financial condition or results of operations.

An important feature of our credit risk management system is our use of an internal credit risk rating and control system through which we identify, measure, monitor and mitigate existing and emerging credit risk of our customers. As this process involves detailed analyses of the customer or credit risk, taking into account both quantitative and qualitative factors, it is subject to human error. In exercising their judgment, our employees may not always be able to assign an accurate credit rating to a customer or credit risk, which may result in our exposure to higher credit risks than indicated by our risk rating and control system.

Some of our tools and metrics for managing credit risk and other risks are based upon our use of observed historical market behavior and assumptions. We rely on quantitative models to measure risks and to estimate certain financial values. Models may be used in such processes as determining the pricing of various products, grading loans and extending credit, measuring interest rate and other market risks, predicting losses, assessing capital adequacy and calculating regulatory capital levels, as well as estimating the value of financial instruments and balance sheet items. Poorly designed or implemented models present the risk that our business decisions based on information incorporating such models will be adversely affected due to the inadequacy of that information. Moreover, our models may fail to predict future risk exposures if the information used in the model is incorrect, obsolete or not sufficiently comparable to actual events as they occur, or if our model assumptions prove incorrect. We seek to incorporate appropriate historical data in our models, but the range of market values and behaviors reflected in any period of historical data is not at all times

- 87-

predictive of future developments in any particular period and the period of data we incorporate into our models may turn out to be inappropriate for the future period being modeled. In such case, our ability to manage risk would be limited and our risk exposure and losses could be significantly greater than our models indicated.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Sales of Unregistered Equity Securities

On October 20, 2014, we completed our initial public offering. As part of our formation in preparation for our initial public offering, on July 9, 2014, we issued and sold 100 shares of our common stock to National Americas Holdings LLC, an indirect, wholly owned subsidiary of NAB, for aggregate cash consideration of $100. This transaction was exempt from registration under the Securities Act under section 4(a)(2) thereof. In addition, on October 17, 2014, we effected a 578,861.14-for-1 split of our outstanding common stock.
