GREAT WESTERN BANCORP, INC.
Notes to Consolidated Financial Statements (Unaudited)




1. Nature of Operations and Summary of Significant Policies
Nature of Operations
Great Western Bancorp, Inc. (the “Company”)The Company is a bank holding company organized under the laws of Delaware and is listed on the New York Stock Exchange ("NYSE")NYSE under the symbol GWB."GWB". The primary business of the Company is ownership of its wholly ownedwholly-owned subsidiary, Great Western Bank (the “Bank”).Bank. The Bank is a full-service regional bank focused on relationship-based business and agri-business banking in Arizona, Colorado, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota and South Dakota. The Company and the Bank are subject to the regulation of certain federal and/or state agencies and undergo periodic examinations by those regulatory authorities. Substantially all of the Company’s income is generated from banking operations.
Basis of Presentation
The accompanying unaudited consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”)GAAP and reflect all adjustments that are, in the opinion of management, necessary for the fair presentation of the financial position and results of operations for the periods presented. All such adjustments are of a normal recurring nature.
Certain previously reported amounts have been reclassified to conform to the current presentation.
The unaudited interim consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended September 30, 2017,2019, which includes a description of significant accounting policies. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year or any other period.
The accompanying unaudited consolidated financial statements include the accounts and results of operations of the Company and its subsidiaries after elimination of all significant intercompany accounts and transactions. The preparation of unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported on the consolidated financial statements and accompanying notes. Actual results could differ from these estimates.
FDIC Indemnification AssetChanges in Significant Accounting Policies
Pursuant to the Company's adoption of ASU 2016-02 and Clawback Liability
FDIC Indemnification assets are includedsubsequent related ASUs as of October 1, 2019, the Company updated its accounting policy related to leases. See Note 12 for new disclosures and policy information related to the Company's leases. There were no other significant changes to the Company's accounting policies from those disclosed in other assetsthe Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2019 that could have a material effect on the Company's consolidated balance sheets.
Core Deposits and Other Intangibles
Core deposits and other intangibles are included in other assets in the consolidated balance sheets.
Loan Servicing Rights
Loan servicing rights are included in other assets in the consolidated balance sheets.
Derivatives
The Company maintains an overall interest rate risk management strategy that permits the use of derivative instruments to modify exposure to interest rate risk. The Company enters into interest rate swap contracts to offset the interest rate risk associated with borrowers who lock in long-term fixed rates (greater than or equal to 5 years to maturity) through a fixed rate loan. Generally, under these swaps, the Company agrees with various swap counterparties to exchange the difference between fixed-rate and floating-rate interest amounts based upon notional principal amounts. These contracts do not qualify for hedge accounting. These interest rate derivative instruments are recognized as other assets or other liabilities on the consolidated balance sheets and measured at fair value, with changes in fair value reported in net realized and unrealized gain (loss) on derivatives on the consolidated statements of income. Since each fixed rate loan is paired with an offsetting derivative contract, the impact to net income is minimized. The Company also has back-to-back swaps with loan customers where the Company enters into an interest rate swap with loan customers to provide a facility to mitigate the interest rate risk associated with offering a fixed rate and simultaneously enters into a swap with an outside third party that is matched in exact offsetting terms. The back-to-back swaps are recorded at fair value and recognized as other assets or other liabilities, depending on the rights or obligations under the contract, on the consolidated balance sheet, with changes in fair value reported in net realized and unrealized gain (loss) on derivatives on the consolidated statements of income.

The Company also has corresponding forward sales contracts related to these interest rate lock commitments. Both the mortgage loan commitments and the related sales contracts are considered derivatives and are recorded at fair value and included in other assets or other liabilities on the consolidated balance sheets with changes in fair value offsetting each other in net realized and unrealized gain (loss) on derivatives on the consolidated statements of income.financial statements.

2. New Accounting PronouncementsStandards
Accounting Standards Adopted in Fiscal Year 2020
In August 2017, the Financial Accounting Standards Board ("FASB")FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which amendsamended the hedge accounting recognition and presentation requirements in ASC 815 to improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities to better align the entity’s financial reporting for hedging relationships with those risk management activities and to reduce the complexity of and simplify the application of hedge accounting. ASU 2017-12 is to be applied to all existingwas effective for the Company on October 1, 2019. For the periods presented, the Company did not designate any derivative financial instruments as formal hedging relationships, and therefore, did not utilize hedge accounting. As such, ASU 2017-12 did not impact the Company's consolidated financial statements.
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires that lessees recognize the assets and liabilities arising from leases on the balance sheet and disclose key information about leasing arrangements. Lessees are required to recognize an obligation for future lease payments measured on a discounted basis and a related right-of-use asset. ASU 2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, Revenue from Contracts with Customers. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, and ASU 2018-11, Leases (Topic 842), Targeted Improvements, which made technical corrections and improvements to the previous ASU issued, including a modified retrospective transition method that allows entities to apply the standard as of the adoption date. In December 2018, the FASB issued ASU 2018-20, Leases (Topic 842): Narrow-Scope Improvements for Lessors, which allowed lessors to exclude sales tax from consideration of the contract through a policy election and clarified treatment of certain lessor costs and variable payments for contracts with lease and nonlease components. The Company adopted this guidance beginning October 1, 2019 using the modified retrospective transition method and all practical expedients available other than the use of hindsight with respect to determining the lease term and assessing impairment of its right-of-use assets. As of the date of adoption, the Company's right-of-use assets and lease liabilities recorded in other assets and accrued expenses and other liabilities on the consolidated balance sheets were $19.9 million and $20.9 million, respectively, arising from operating leases in which the Company is the lessee. The Company also recognized a cumulative effect adjustment of $0.2 million as a result of remeasuring a pre-existing lease impairment as of the date of adoption. These ASUs did not have a material impact on the timing of expense or income recognition in the Company's consolidated statements of income.
Accounting Standards Not Yet Adopted in Fiscal Year 2020
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes in the Disclosure Requirements for Fair Value Measurement, which eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2018-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted in any interim period, with the effect of adoption reflected as of the beginning of the fiscal year of adoption. The Company is currently evaluating the potential impact of ASU 2017-12 on our consolidated financial statements.
In March 2017, FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities, which shortens the amortization period for certain callable debt securities held at a premium to the earliest call date unless applicable guidance related to certain pools of securities is applied to consider estimated prepayments. Under prior guidance, entities were generally required to amortize premiums on individual, non-pooled callable debt securities as a yield adjustment over the contractual life of the security. There is no accounting change for debt securities held at a discount. ASU 2017-08 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15,

2018,2019, with early adoption permitted. TheEntities are also allowed to elect to early adopt the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until after their effective date. As ASU 2018-13 only revises disclosure requirements, the Company early adopteddoes not believe this ASU 2017-08 duringwill have a material impact on the first quarter of fiscal year 2018. There was no cumulative effect adjustment necessary to the Company's consolidated financial statements.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which addresses timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU 2016-13 requires institutions to measure all expected credit losses related to financial assets measured at amortized costs with an expected loss model based on historical experience, current conditions and reasonable and supportable forecasts relevant to affect the collectability of the financial assets, which is referred to as the current expected credit loss (CECL) model. The ASU 2016-13 requires enhanced disclosures, including qualitative and quantitative requirements, to help understand significant estimates and judgments used in estimating credit losses, as well as provide additional information about the amounts recorded in the financial statements. From November 2018 through February 2020, the FASB issued ASUs which made technical corrections and improvements to the previous ASU 2016-13issued (ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments, Credit Losses; ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments; ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments - Credit Losses; and ASU 2020-02, Financial Instruments - Credit Losses (Topic 326) and Leases (Topic 842)). The ASUs require the use of the modified retrospective approach for adoption. These ASUs will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted after December 15, 2018. The amendment requires the use of the modified retrospective approach for adoption.Company continues to make progress on its implementation plan including continuing to work through finalizing processes, controls and an independent model validation and we are on track to adopt as required on October 1, 2020.

In February 2016,December 2019, the FASB issued ASU No. 2016-02, Leases2019-12, Income Taxes (Topic 842)740): Simplifying the Accounting for Income Taxes, which requires that lessees recognizeaims to simplify the assetsaccounting for income taxes by removing certain exceptions to the general principles and liabilities arising from leases on the balance sheetalso simplification of areas such as franchise taxes, step-up in tax basis goodwill, separate entity financial statements and disclosing key information about leasing arrangements. Lessees will be required to recognize an obligation for future lease payments measured on a discounted basis and a related right-of-use asset.interim recognition of enactment of tax laws or rate changes. The ASU 2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, "Revenue from Contracts with Customers." ASU 2016-02 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018.2020, with early adoption permitted. The Company is currently evaluating the potential impact of ASU 2016-022019-12 on ourthe consolidated financial statements.
In January 2016,2020, the FASB issued ASU No. 2016-01, Financial Instruments2020-01, Investments - Overall (Subtopic 825-10)Equity Securities (Topic 321), Investments - RecognitionEquity Method and Measurement of Financial AssetsJoint Ventures (Topic 323), and Financial LiabilitiesDerivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323 and Topic 815, which requires equity investments, in general, to be measured at fair value with changes in fair value recognized in earnings. It also eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost, requires entities to use the exit price notion when measuring fair value, requires an entity to present separately in other comprehensive income the portion of the total change in fair value of a liability resulting from a change in the measurement category and form on the balance sheet or accompanying notes, clarifies that an entity should evaluateconsider observable transactions that require it to either apply or discontinue the needequity method of accounting for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity's other deferred tax assets, and simplifiespurposes of applying the impairment assessment of equity investments without readily determinable fair values.value measurement alternative. The ASU 2016-01 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017,2020, with early adoption permitted. The Company does not believe ASU 2016-01 willexpect adoption to have a material impact on ourthe consolidated financial statements.
In May 2014,March 2020, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers2020-04, Reference Rate Reform (Topic 606)848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which implementsprovides optional expedients and exceptions for a more robust frameworklimited time period to ease the potential burden in accounting for reference rate reform on financial reporting. The amendments in ASU 2020-04 are elective for entities with contracts, including derivative contracts, that clarifiesreference LIBOR or some other reference rate that are expected to be discontinued. For the principles for recognizing revenue and gives greater consistency and comparability in revenue recognition practices. In the new framework,Company's cash flow hedges, ASU 2020-04 allows: (i) an entity recognizes revenueto change the reference rate without having to designate the hedging relationship; (ii) for cash flow hedges in an amount that reflects the consideration to which the designated hedged risk is LIBOR, allows an entity expects to assert that it remains probable that the hedged forecasted transaction will occur; and (iii) allows an entity to change the designated method used to assess hedge effectiveness and simplifies or temporarily suspends the assessment of hedge effectiveness for hedging relationships. ASU 2020-04 must be entitled in exchange for goods or services.applied prospectively and was effective immediately upon issuance and remains effective through December 31, 2022. The Company is currently evaluating the impact that adopting this new model requires the identification of performance obligations included in the contract with customers, a determination of the transaction price and an allocation of the price to those performance obligations. The entity recognizes revenue when performance obligations are satisfied. In August 2015, the FASB issued ASU No. 2015-14, which deferred the effective date of ASU No. 2014-09 to annual reporting periods beginning after December 15, 2017. In March 2016, the FASB issued ASU No. 2016-08, which intends to improve the operability and understandability of the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU No. 2016-10, which clarifies guidance pertaining to the identification of performance obligations and the licensing implementation. In May 2016, the FASB issued ASU Nos. 2016-11 and 2016-12, which further clarify guidance and provide practical expedients related to the adoption of ASU No. 2014-09. Theaccounting standard permits the use of either the retrospective or cumulative effect transition method. The standard, along with subsequent guidance from FASB, lists several items that are specifically out of scope for ASU 2014-09, including but not limited to: core interest income, derivative instruments, investments, and loan origination fees.
To address the new standard, the Company formed a working group and has completed the initial scoping phase to determine which revenue streams may be subject to accounting or disclosure changes upon adoption in October of 2018. Based on this preliminary analysis, we do not anticipate significant changes as a result of implementing the standard, but will concludehave on the quantitative and qualitative impacts once we have completed our review of key contracts for any in-scope items over the coming months.consolidated financial statements.

2019.
Securities with an estimated fair value of approximately $990.6$918.8 million and $951.4$863.9 million at DecemberMarch 31, 20172020 and September 30, 2017,2019, respectively, were pledged as collateral on public deposits, securities sold under agreements to repurchase, and for other purposes as required by contractual obligation or permitted by law. The counterparties do not have the right to sell or pledge the securities the Company has pledged as collateral.
As detailed in the following tables, certain investments in debt securities, which are approximately 90%12% and 68%36% of the Company’s investment portfolio at estimated fair value at DecemberMarch 31, 20172020 and September 30, 2017,2019, 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 notmore-likely-than-not the Company will be required to sell the securities before the recovery of their amortized cost basis, which may be maturity, the Company does not consider the securities to be other-than-temporarily impaired at DecemberMarch 31, 20172020 or September 30, 2017.2019.

Nonaccrual
Interest income on loans is accrued daily on the outstanding balances. Accrual of interestA loan is discontinuedplaced on nonaccrual status when management believes, after considering collection efforts and other factors, the borrower’s financialborrowers' condition is such that collection of interest is doubtful, which is generally at 90 days past due. Generally, whenWhen loans are placed on nonaccrual status, accrual of interest is discontinued and interest receivable is reversed against interest income in the current period. Interest payments received thereafter are applied as a reduction to the remaining principal balance as long as concern exists as to the ultimate collection of the principal. Loans are removed from nonaccrual status when they become current as to both principal and interest and concern no longer exists as to the collectability of principal and interest.
The following table presents the Company’s nonaccrual loans at DecemberMarch 31, 20172020 and September 30, 2017,2019, excluding ASC 310-30 loans.

AFor purposes of the table above, a loan is considered to be in payment default once it is 90 days or more contractually past due under the modified terms. The table above includes loans that experienced a payment default during the period, but may be performing in accordance with the modified terms as of the balance sheet date. ForThere were $0.3 million and $0.0 million for the three months ended DecemberMarch 31, 20172020 and 2016, there were $0.62019, respectively, and $0.3 million and $0.0 million for the six months ended March 31, 2020 and 2019, respectively, of loans removed from TDR status as they were restructured at market terms and are performing.
5. Allowance for Loan and Lease Losses
The allowance for loan and lease losses under the incurred loss model is determined based on an ongoing evaluation, driven primarily by monitoring changes in loan risk grades, delinquencies, and other credit risk indicators, which isare inherently subjective. The Company considers the uncertainty related to certain industry sectors and the extent of credit exposure to specific borrowers within the portfolio. In addition, consideration is given to concentration risks associated with the various loan portfolios, and current economic conditions and other environmental factors that might impact the portfolio. The Company also considers changes, if any, in underwriting activities, the loan portfolio composition (including product mix and geographic, industry, or customer-specific concentrations), trends in loan performance, the level of allowance coverage relative to similar banking institutions under an incurred loss model and macroeconomic factors, such as changes in unemployment rates, gross domestic product, and consumer bankruptcy filings.
Changes to the allowance for loan and lease losses are made by charges to the provision for loan and lease losses, which is reflected on the consolidated statements of income. Past due status is monitored as an indicator of credit deterioration. Loans that are 90 days or more past due are put on nonaccrual status unless a repayment is eminent. Loans deemed to be uncollectible are charged off against the allowance for loan and lease losses. Recoveries of amounts previously charged-off are credited to the allowance for loan and lease losses.
The allowance for loan and lease losses consist of reserves for probable losses that have been identified related to specific borrowing relationships that are individually evaluated for impairment (“("specific reserve”reserve"), as well as probable losses inherent in ourthe loan portfolio that are not specifically identified (“("collective reserve”reserve").
The specific reserve relates to impaired loans. A loan is impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due (interest as well as principal) according to the contractual terms of the loan agreement. Specific reserves are determined on a loan-by-loan basis based on management’s best estimate of the Company's exposure, given the current payment status of the loan, the present value of expected payments, and the value of any underlying collateral. Impaired loans also include loans modified in troubled debt restructurings.TDRs. Generally, the impairment related to troubled debt restructurings is measured based on the fair value of the collateral, less cost to sell, or the present value of expected payments relative to the unpaid principal balance. If the impaired loan is identified as collateral dependent, then the fair value of the collateral method of measuring the amount of the impairment is utilized. This method requires obtaining an independent appraisal of the collateral and reducing the appraised value by applying a discount factor to the appraised value, if necessary, and including costs to sell.
Management’s estimate for collective reserves reflects losses incurred in the loan portfolio as of the consolidated balance sheet reporting date. Incurred loss estimates primarily are based on historical loss experience and portfolio mix. Incurred loss estimates may be adjusted for qualitative factors such as current economic conditions and current portfolio trends including credit quality, concentrations, aging of the portfolio, and/or significant policy and underwriting changes.

changes, which may not be reflected in the historical loss experience.

For acquired loans not accounted for under ASC 310-30 (purchased non-impaired), the Company utilizes specific and collective reserve calculation methods similar to originated loans. The required ALLL for these loans is included in the individually evaluated for impairment bucket of the ALLL if the loan is rated substandard or worse, and in the collectively evaluated for impairment bucket for pass rated loans.
The Company maintains an ALLL for acquired loans accounted for under ASC 310-30 as a result of impairment to loan pools arising from the periodic re-valuation of these loans. Any impairment in the individual pool is generally recognized in the current period as provision for loan and lease losses. Any improvement in the estimated cash flows, is generally not recognized immediately, but is instead reflected as an adjustment to the related loan pools yield on a prospective basis once any previously recorded impairment has been recaptured.

6. Accounting for Certain Loans Acquired with Deteriorated Credit Quality
In June 2010 and May 2016, the Company acquired certain loans in the TierOne Bank and HF Financial transactions, respectively, that had deteriorated credit quality (ASCknown as ASC 310-30 loans or Purchase Credit Impaired loans).purchased credit impaired loans. Several factors were considered when evaluating whether a loan was considered a purchased credit impaired loan, including the delinquency status of the loan, updated borrower credit status, geographic information and updated loan-to-values ("LTV").loan-to-values. Further, these purchased credit impaired loans had differences between contractual amounts owed and cash flows expected to be collected, that were at least in part, due to credit quality. U.S. GAAP allows purchasers to aggregate purchased credit impaired loans acquired in the same fiscal quarter in one or more pools, provided that the loans have common risk characteristics. A pool is then accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows.
Loan pools are periodically reassessed to determine expected cash flows. In determining the expected cash flows, the timing of cash flows and prepayment assumptions for smaller, homogeneous loans are based on statistical models that take into account factors such as the loan interest rate, credit profile of the borrowers, the years in which the loans were originated, and whether the loans are fixed or variable rate loans. Prepayments may be assumed on large individual loans that consider similar prepayment factors listed above for smaller homogeneous loans.
The re-assessment of purchased credit impaired loans resulted in the following changes in the accretable yield during the three and six months ended DecemberMarch 31, 20172020 and 2016:

As with any financial instrument, derivative financial instruments have inherent risk including adverse changes in interest rates. The Company’s exposure to derivative credit risk is defined as the possibility of sustaining a loss due to the failure of the counterparty to perform in accordance with the terms of the contract. Credit risks associated with interest rate swaps are similar to those relating to traditional on-balance sheet financial instruments. The Company manages interest rate swap credit risk with the same standards and procedures applied to its commercial lending activities.
Credit-risk-related contingent features
The Company has agreements with its derivative counterparties that contain a provision where if the Company or the derivative counterparty fails to maintain its status as a well/adequately capitalized institution, then the other party has the right to terminate the derivative positions and the Company or the derivative counterparty would be required to settle its obligations under the agreements. The Company has minimum collateral postingpledging thresholds with its Swap Dealers and Futures Clearing Merchant.
In 2018, the Company entered into RPAs with some of its derivative counterparties.
As of December 31, 2017 and September 30, 2017,counterparties to assume the termination value of derivatives in a net liability positioncredit exposure related to these agreements was $10.7 million and $20.3 million, respectively, which includes accrued interest but excludes any adjustment for nonperformance risk.

9. The Fair Value Option Forfor Certain Loans
The Company has elected to measure certain long-term loans at fair value to assist in managing the interest rate risk for longer-term loans. This fair value option was elected upon the origination of these loans. Interest income is recognized in the same manner as interest on non-fair value loans.
See Note 18 for additional disclosures regarding the fair value of the fair value option loans.
Long-term loans for which the fair value option has been elected had a net favorable difference between the aggregate fair value and the aggregate unpaid loan principal balance and written loan commitment amount of approximately $1.3 million and $8.8$57.5 million at DecemberMarch 31, 20172020 and a net favorable difference of approximately $34.2 million at September 30, 2017, respectively.2019. The total unpaid principal balance of these long-term loans was approximately $978.9$734.6 million and $1.01 billion$778.8 million at DecemberMarch 31, 20172020 and September 30, 2017,2019, respectively. The fair value of these loans is included in total loans in the consolidated balance sheets and are grouped with commercial real estate, agricultural and commercial non-real estate loans in Note 4. As of DecemberMarch 31, 20172020 and September 30, 2017,2019, there were loans with a fair value of $14.1$9.1 million and $14.7$16.5 million, respectively, which were greater than 90 days past due or in nonaccrual status with an unpaid principal balance of $15.0$12.1 million and $17.0$17.8 million, respectively.
Changes in fair value for items for which the fair value option has been elected were an increase in fair value of $35.5 million and $20.6 million for the line itemsthree and six months ended March 31, 2020, respectively, and an increase in which thesefair value of $14.0 million and $33.2 million for the three and six months ended March 31, 2019, respectively.

In accordance with ASC 350-20, the Company conducts a goodwill impairment test at least annually, or more frequently as events occur or circumstances change that would more-likely-than-not reduce the fair value below its carrying amount. In the second quarter of fiscal year 2020, the onset of the COVID-19 pandemic prompted the Company to assess qualitative and quantitative factors to determine whether it was more-likely-than-not the fair value of the Company was less than the carrying amount.
The Company assessed relevant events and circumstances, including macroeconomic conditions, industry and market considerations, overall financial performance, changes in the composition or carrying amount of assets and liabilities, the market price of the Company's common stock and other relevant facts. The Company performed both a market capitalization approach and a discounted cash flow approach to determine the fair value of the Company. As a result of the analysis, the Company recognized a goodwill impairment charge of $740.6 million for both the three and six months ended March 31, 2020. NaN goodwill impairment charge was recognized for the three and six months ended March 31, 2019.

ASC 842 requires a lease, whether classified as an operating lease or a financing lease, be accounted for as a right-of-use asset ("ROU asset") with a related lease liability recorded at the present value of the lease payments. The ROU asset represents the Company's right to use an underlying asset for the lease term and is included in other assets on the Company's consolidated balance sheets. The lease liability represents the Company's obligation to make lease payments and is included in accrued expenses and other liabilities on the Company's consolidated balance sheets. The cost of the lease is recognized on a straight-line basis over the lease term as lease expense. As permitted by ASC 842, the Company elected not to reassess (i) whether any expired or existing contracts are leases or contain leases, (ii) the lease classification of any expired or existing leases, and (iii) the initial direct costs for existing leases.
11. Loan Servicing Rights
Loan servicing rightsSubsequent to the adoption of ASC 842, the Company assesses contracts at inception to determine whether the contract is a lease or contains an embedded lease. A ROU asset and lease liability is recorded on the consolidated balance sheet for all leases except those with an original lease term of twelve months or less. Most of these leases include one or more renewal options, and certain leases also include lessee termination options. As these renewal options are created when residential mortgage loansnot generally considered reasonably certain of exercise, they are soldnot included in the secondary marketlease term.
The Company leases certain branch and corporate offices, land and ATM facilities through operating leases with terms typically ranging from 1 to 15 years, with the seller retaining the right to service those loans and receive servicing income over the lifelongest term having a lease expiration of the loan.March 31, 2034.

GREAT WESTERN BANCORP, INC.
Notes to Consolidated Financial Statements (Unaudited)


At December 31, 2017, the Company had an income tax payable to the Internal Revenue Service (the "IRS") of $4.6 million, which is included in other liabilities on the consolidated balance sheets. At September 30, 2017, the Company had an income tax receivable from the IRS of $4.6 million, which is included in other assets on the consolidated balance sheets. The Company is no longer subject to U.S. federal, state and local or non-U.S. income tax examinations by tax authorities for years before 2014.
On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "Tax Reform Act"), was enacted into law. Beginning in 2018, the Tax Reform Act reduces the federal tax rate for corporations from 35% to 21% and changes or limits certain tax deductions. Because of the Company's September 30 fiscal year end, a blended statutory rate of 24.5% is applied to all net income before taxes generated during the current fiscal year. The new blended statutory rate reduced the provision for income taxes by approximately $5.0 million for the three months ended December 31, 2017. Another result of the lower corporate tax rate this quarter was the Company recording a revaluation discrete tax adjustment of $13.6 million to reduce its net deferred tax assets, which increased the provision for income taxes. The actual impact of the revaluing deferred taxes may vary from the estimated charge to provision of $13.6 million due to uncertainties in our preliminary estimates and the effect of further clarification of the new law that cannot be estimated at this time.
The Bank's effective tax rate for the three months ended December 31, 2017 was 49.5%, compared to 30.8% for the prior quarter. The increase in the effective tax rate during the quarter mostly resulted from the revaluation of deferred taxes. For 2018, the Bank expects its annual effective tax rate to be approximately 26%.
Uncertain tax positions were not significant at December 31, 2017 or September 30, 2017.
16. Employee Benefit Plans
Profit Sharing Plan
The Company participates in a multiple employer 401(k) profit sharing plan ("the 401(k) Plan"). All employees are eligible to participate, beginning with the first day of the month coincident with or immediately following the completion of one year of service and having reached the age of 21. In addition to employee contributions, the Company may contribute discretionary amounts for eligible participants. Contribution rates for participating employees must be equal. The Company contributed $1.8$1.6 million and $1.5$3.3 million to the 401(k) Plan for the three and six months ended DecemberMarch 31, 20172020, respectively, and 2016,$1.1 million and $2.9 million for the three and six months ended March 31, 2019, respectively.
Defined Benefit Plan
The Company acquired a noncontributory (cash balance) defined benefit pension plan ("the Pension Plan") from HF Financial which covers former employees of HF Financial and its wholly-owned subsidiaries. Effective July 1, 2015, the Pension Plan was frozen which eliminates future contributions for qualified individuals.
On November 27, 2017, the Company's Board of Directors voted to terminate the Pension Plan, effective February 1, 2018. In order to settle its liabilities under the Pension Plan, the Company will offer participants the option to receive either an annuity purchased from an insurance carrier or a lump-sum cash payment. If the total $3.1 million value of the Pension Plan's cash assets is insufficient to cover the lump-sum payouts and annuity purchases, the Company will contribute the necessary funds to complete the termination of the Pension Plan. In addition to plan assets, the Company has a $2.3 million pension liability recorded as of December 31, 2017. The required final contribution is subject to a number of factors, including changes in interest rates and the exact proportion of participants electing a lump-sum distribution versus an annuity. The Company estimates that the total benefit payments will be $5.4 million as part of Pension Plan termination. At this time, the Company is unable to estimate the net income or expense associated with terminating the Pension Plan, but believes the amount will not be material to the financial statements.
The Company anticipates completing the transfer of all liabilities and administrative responsibilities under the Pension Plan by the end of fiscal third quarter 2018. Once this process is complete, the Company will no longer have any remaining pension obligations and thus no periodic pension expense.
17. Stock-Based Compensation
On September 26, 2014, the Board of Directors adopted, and on October 10, 2014, NAB, at that time ourthe Company's controlling shareholder, approved the Great Western Bancorp, Inc. 2014 Omnibus Incentive Compensation Plan (the “2014 Plan”("2014 Plan"), the Great Western Bancorp, Inc. 2014 Non-Employee Director Plan (the “2014("2014 Director Plan”Plan"), and the Great Western Bancorp, Inc. Executive Incentive Compensation Plan (the “Bonus Plan”("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. On February 22, 2018, the Company's stockholders approved amendments to the 2014 Plan and the 2014 Director Plan to increase the number of shares available for future grants under the Plans. 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/orand, if applicable, performance objectives have been obtained. During the vesting periods, participants do not have voting rights and dividends are accumulated until the time upon which the award vests. Upon specified events, as defined in the Plans, stock unit awards that have not vested and/or performance hurdles that have not been met will be forfeited.
Based on the substantive terms of each award, restricted and performance-based awards are classified as equity awards and accounted for under the treasury stock method. The fair value of equity-classified awards is based on the market price of the stock on the measurement date and is amortized as compensation expense on a straight-line basis over the vesting or performance period.

Stock compensation is recognized based on the number of awards to vest using actual forfeiture amounts. For performance-based stock awards, an estimate is made of the number of shares expected to vest as a result of actual performance against the performance targets to determine the amount of compensation expense to be recognized. The estimate is reevaluated quarterly and total compensation expense is adjusted for any change in the current period. Stock-based compensation expense is included in salaries and employee benefits expense in the consolidated statements of income. For the three months ended December 31, 2017 and 2016, stockStock compensation expense was $1.5$1.3 million and $1.6$2.9 million for the three and six months ended March 31, 2020, respectively, and $1.4 million and $3.1 million for the three and six months ended March 31, 2019, respectively. Related income tax benefits recognized were $0.5$0.3 million and $0.6$0.7 million for the three and six months ended DecemberMarch 31, 20172020, respectively and 2016,$0.4 million and $0.8 million for the three and six months ended March 31, 2019, respectively.

18. Fair Value Measurements
The Company measures, monitors and discloses certain of its assets and liabilities on a fair value basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value guidance also establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance describes the following three levels of inputs that may be used to measure fair value are as follows:value:
Level 1 Quoted prices in active markets for identical assets or liabilitiesliabilities;
Level 2Observable 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 3Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the 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; and
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.
32-


GREAT WESTERN BANCORP, INC.
Notes to Consolidated Financial Statements (Unaudited)
Level 1 inputs are considered to be the most transparent and reliable and Level 3 inputs are considered to be the least transparent and reliable. The Company assumes the use of the principal market to conduct a transaction of each particular asset or liability being measured and then considers the assumptions that market participants would use when pricing the asset or liability. Whenever possible, the Company first looks for quoted prices for identical assets or liabilities in active markets (Level 1 inputs) to value each asset or liability. However, when inputs from identical assets or liabilities on active markets are not available, the Company utilizes market observable data for similar assets and liabilities. The Company maximizes the use of observable inputs and limits the use of unobservable inputs to occasions when observable inputs are not available. The need to use unobservable inputs generally results from the lack of market liquidity of the actual financial instrument or of the underlying collateral. Although in some instances, third party price indications may be available, limited trading activity can challenge the observability of these quotations.
Assets and Liabilities Measured at Fair Value on a Recurring Basis
Following is a description of the valuation methodologies and inputs used for assets and liabilities measured at fair value on a recurring basis and recognized in the accompanying consolidated balance sheets, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy.
Securities Available for Sale
Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include U.S. Treasury securities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows and classified as Level 2 securities. Level 2 securities include mortgage-backed, states and political subdivisions, and other securities. Where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Level 3 securities were immaterial at DecemberMarch 31, 20172020 and September 30, 2017.2019.
Interest Rate Swaps and Loans
Interest rate swaps are valued by the Company's Swap Dealers using cash flow valuation techniques with observable market data inputs. The fair value of loans accounted for under the fair value option represents the net carrying value of the loan, plus the equal and opposite amount of the value of the swap needed to hedgeoffset the interest rate risk and an adjustment for credit risk based on ourthe Company's 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 hedgeinterest rate swap of the loans in the case of early prepayment or termination. The adjustment for credit risk on loans accounted for under the fair value option is not significant to the overall fair value of the loans. The fair values estimated by the Company's Swap Dealers use interest rates that are observable or that can be corroborated by observable market data and, therefore, are classified within Level 2 of the valuation hierarchy. The Company has entered into Collateral Agreements with its Swap Dealers and Futures Clearing Merchant which entitle it to receive collateral to cover market values on derivatives which are in asset position, thus a credit risk adjustment on interest rate swaps is not warranted. The Company regularly enters into interest rate lock commitments on mortgage loans to be held for sale with corresponding forward sales contracts related to these interest rate lock commitments, the fair values of which are calculated by applying observable market values from Fannie Mae TBA pricing to each interest rate lock commitment and forward sales contract, therefore, are classified within Level 2 of the valuation hierarchy. The Company also has back-to-back swaps with loan customers, with corresponding swaps with an outside third party in exact offsetting terms.

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

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
Following is a description of the valuation methodologies used for assets and liabilities measured at fair value on a nonrecurring basis and recognized in the accompanying consolidated balance sheets, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy.
Other Repossessed Property
Other repossessed property consists of loan collateral that has been repossessed through foreclosure. This collateral is comprised of commercial and residential real estate and other repossessed assets. Other repossessed property is recorded initially at fair value of the collateral less estimated selling costs. Subsequent to foreclosure, valuations are updated periodically, and the assets may be marked down further to fair value less selling costs, reflecting a valuation allowance. Fair value measurements may be based upon appraisals, third-party price opinions, or internally developed pricing methods. These measurements are classified as Level 3.

Notes to Consolidated Financial Statements (Unaudited)
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.
Mortgage Loans Held for Sale
Fair value of mortgage loans held for sale is based on either quoted prices for the same or similar loans, or values obtained from third parties, or are estimated for portfolios of loans with similar financial characteristics and are therefore considered a Level 2 valuation.
Loan Servicing Rights
Fair value is determined at a tranche level, based on market prices for comparable mortgage servicing contracts (Level 3), when available, or alternatively based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model utilizes interest rate, prepayment speed, and default rate assumptions that market participants would use in estimating future net servicing income and that can be validated against market data (Level 3).
Property Held for Sale
This real estate property is carried in premises and equipment as property held for sale at fair value based upon the transactional price if available, or the appraised value of the property.

Disclosures about Fair Value of Financial Instruments
For financial instruments that have quoted market prices, those quotes are used to determine fair value. Financial instruments that have no defined maturity, have a remaining maturity of 180 days or less, or reprice frequently to a market rate are assumed to have a fair value that approximates carrying value, after taking into consideration any applicable credit risk. If no market quotes are

Notes to Consolidated Financial Statements (Unaudited)


available, financial instruments are valued by discounting the expected cash flows using an estimated current market interest rate for the financial instrument.
The short maturity of the Company’s assets and liabilities results in having a significant number of financial instruments whose fair value equals or closely approximates carrying value. Such financial instruments are reported in the following consolidated balance sheet categories: cash and cash equivalents, securities sold under agreements to repurchase, and accrued interest.
Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments are accounted for at amortized cost and include premises and equipment, deferred income taxes, goodwill, and core deposit and other intangibles. In addition,Additionally, in accordance with the tax ramifications related to the realization of unrealized gainsdisclosure guideline, receivables and losses can have a significant effect onpayables due in one year or less, insurance contracts, equity investments not accounted for at fair value, estimates and have not been considered in the estimates.
deposits with no defined or contractual maturities are excluded. Off-balance sheet instruments (commitments to extend credit and standby letters of credit) are generally short-term and at variable rates. Therefore, both the carrying amount and the estimated fair value associated with these instruments are immaterial. Fair values for balance sheet instruments as of December 31, 2017 and September 30, 2017 are as follows:

The following methods and assumptions were used in estimating the fair value of financial instruments that were not previously disclosed:
Cash and cash equivalents: Due to the short term nature of cash and cash equivalents, the estimated fair value is equal to the carrying value and they are categorized as a Level 1 fair value measurement.
Loans, net excluding fair valued loans and loans held for sale: The fair value of the loan portfolio is estimated using observable inputs including estimated cash flows, and discount rates based on interest rates currently being offered for loans with similar terms, to borrowers of similar credit quality. Loans held for investment are categorized as a Level 3 fair value measurement.
Accrued interest receivable: Due to the nature of accrued interest receivable, the estimated fair value is equal to the carrying value and they are categorized as a Level 2 fair value measurement.
Cash Surrender Value of Life Insurance Policies: Fair value is equal to the cash surrender value of the life insurance policies.
Federal Home Loan Bank stock: The carrying amount of FHLB stock approximates its fair value as it can only be redeemed with the FHLB at par value. Federal Home Loan Bank stock has been categorized as a Level 2 fair value measurement.
Deposits: The estimated fair value of deposits with no stated maturity, such as non-interest bearing demand deposits, savings, NOW, and money market accounts, is equal to the amount payable on demand. The fair value of interest-bearing time deposits is based on the discounted value of contractual cash flows of such deposits, taking into account the option for early withdrawal. The discount rate is estimated using the rates offered by the Company, at the respective measurement dates, for deposits of similar maturities. Deposits have been categorized as a Level 2 fair value measurement.

Fair values for on-balance sheet instruments as of March 31, 2020 and September 30, 2019 are as follows.
FHLB advances and other borrowings: The fair value of FHLB advances and other borrowings is estimated using discounted cash flow analysis, based on current incremental borrowing rates for similar types of borrowing arrangements. In the absence of a reasonably precise methodology to determine the fair value of the credit agreement, carrying value has been used to represent fair value. FHLB advances and other borrowings have been categorized as a Level 2 fair value measurement.

19. Earnings per Share
Basic earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding determined for the basic earnings per share calculation plus the dilutive effect of stock compensation using the treasury stock method.
The following information was used in the computation of basic and diluted earnings per share (EPS) for the three and six months ended DecemberMarch 31, 20172020 and 2016:2019.

Overview
We are a full-service regional bank holding company focused on relationship-based business and agribusinessagri-business banking. We serve our customers through 173175 branches in attractive markets in nine states: Arizona, Colorado, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota and South Dakota.
Our bankBank was established more than 80 years ago and we have achieved strong market positions by developing and maintaining extensive local relationships in the communities we serve. By leveraging our business and agribusinessagri-business focus, presence in attractive markets, highly efficient operating model and robust approach to risk management, we have achieved significant and profitable growth—both organically and through disciplined acquisitions. We provide financial results based on a fiscal year ending September 30 as a single reportable segment.
The principal sources of our revenues and cash flows are: (i) interest and fees earned on loans made or held by our bank;Bank; (ii) interest on fixed income investments held by our bank;Bank; (iii) fees on wealth management services; (iv) service charges on deposit accounts maintained at our bank;Bank; (v) gain on the sale of loans held for sale (vi) gains on sales of securities; and (vii) merchant and card fees. Our principal expenses are: (i) interest expense on deposit accounts and other borrowings; (ii) salaries and employee benefits; (iii) data processing and communication costs primarily associated with maintaining our bank'sBank's loan and deposit functions; (iv) occupancy expenses for maintaining our bank'sBank's facilities; (v) professional fees;fees, including FDIC insurance assessments; (vi) business development; (vii) FDIC insurance assessments; and (viii)(vii) other real estate owned expenses. The largest component contributing to our net income is net interest income, which is the difference between interest earned on earning assets (primarily loans and investments) and interest paid on interest-bearing liabilities (primarily deposit accounts and other borrowings). One of management's principal functions is to manage the spread between interest earned on earning assets and interest paid on interest-bearing liabilities in an effort to maximize net interest income while maintaining an appropriate level of interest rate risk.

Impact and Response to COVID-19 Pandemic
We conduct business in nine states, including Arizona, Colorado, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota and South Dakota. Many of these states have placed or are considering placing significant restrictions on companies and individuals in March 2020 as a result of the COVID-19 pandemic. As a financial institution, we are considered an essential business and therefore continue to operate on a modified basis to comply with governmental restrictions and public health authority guidelines. Our bank lobbies are closed to the general public, although business is still being transacted through drive-up facilities, online, telephone or by appointment. Although we believe these arrangements will remain in effect until the restrictions are lifted by governmental authorities, we continue to operate and maintain our customer relationships. The health and safety of our employees and customers is a major concern to our management and every effort is being made to have employees work from home or, if working from one of our locations is required, to maintain appropriate social distancing and observe other health precautions.

ImpactThrough this time of disruption we have remained open for business supporting our customers while implementing our business continuity plan to mitigate the risks of the Tax Cutsspread of COVID-19 to our employees and Jobs Actcustomers. As of 2017
The Tax Cuts and Jobs Act of 2017 significantly impacted the Company's financial results for the quarter and going forward. The three main impacts include:
A nonrecurring reductionApril 24th, we have more than 750 employees working remotely from home with those still in the carrying valueoffice appropriately spaced, 97% of our branches open with limited access, increased functionality of ATM, online banking and mobile channels, and processed 2,300 applications approved for Paycheck Protection Program loans totaling over $600.0 million. We have also taken such other actions as social distancing, restrictions on in-person meetings and conferences, Company travel restrictions and increased sanitary protocols. We believe these actions offer the Company's deferred taxes of $13.6 million, equatingbest protection for our employees and customers, an enhance our ability to $0.23, or 1.3%, of the Company's tangible book value per share and a reduction of approximately 15 basis pointscontinue providing our banking services.
Financial results this quarter included several items linked to the total capital ratio as of December 31, 2017 and $0.23 per diluted share for the quarter ended December 31, 2017;
A reduction in the statutory federal tax rate upon which the Company's net income before taxes is taxed beginning with the current fiscal year ending September 30, 2018. Because of the Company's fiscal year end, a blended statutory federal tax rate of 24.5% is applied to all net income before taxes generated during the current fiscal year and the overall effective tax rate for the fiscal year is expected to be approximately 26.0%. Compared to the previous statutory tax rate, the blended rate reduced the provision for income taxes by approximately $5.0 million for the quarter ended December 31, 2017. Beginning in fiscal year 2019, the Company's net income will be taxed at the 21.0% statutory federal tax rate; and
A reduction in the tax-related benefit generated by tax-advantaged assets. The tax equivalent adjustment to net interest income and net interest margin was $1.6 million for the current quarter, compared to $2.1 million in the prior quarter, on a consistent asset base. This change reduced net interest margin and adjusted net interest marginin the current quarterby approximately 2 basis points and increased our efficiency ratio by a negligible amount.
The actual impact of the revaluing deferredCOVID-19 pandemic. Most significantly, we recognized an impairment included in noninterest expense of $742.4 million, of which $622.4 million stemmed from goodwill related to the acquisition of Great Western Bank in 2008 by National Australia Bank, $118.2 million from goodwill related to subsequent acquisitions and $1.8 million from certain intangible assets, which were considered impaired given the market and valuation disruption during the quarter. The expense was offset in part by a related benefit from income taxes may varyof $29.3 million.
In addition, the COVID-19 impacts included $73.8 million in several credit and other related charges for loan and other real estate reserves, including a $59.7 million charge for general allowance increases in provision expense under the incurred loss model, $7.1 million and $3.3 million of charges for fair value credit risk and derivative reserves in noninterest income, respectively, a $3.3 million write down on an OREO hotel property negatively impacted by COVID-19 pandemic travel restrictions, and $0.4 million of charges for the reserve on unfunded commitments in noninterest expenses. All of these pretax expenses are offset in part by a related benefit from income taxes of $17.2 million. See "—Non-GAAP Financial Measures" section in this document for further discussion of the estimated chargeabove items. Our management believes additional increases in credit and other related charges could occur if the effects of the COVID-19 restrictions continue to provisionnegatively impact the loan portfolio.
Furthermore, the onset of $13.6 millionthe COVID-19 pandemic has significantly heightened the level of challenges, risks and uncertainties facing our Company and its operations, including the following:
Market interest rates have declined significantly and these reductions, especially if prolonged, could adversely affect our net interest income, net interest margin and earnings;
We anticipate a potential slowdown in demand for our products and services, including the demand for traditional loans, although we believe the decline will likely be offset due to uncertaintiesthe new volume of PPP loans under the CARES Act and other governmental programs established in response to the pandemic;
The inability of our customers to meet their loan commitments and could result in increased risk of delinquencies, defaults, foreclosures, declining collateral values and ability of our borrowers to repay their loans resulting in losses to our Company;
The COVID-19 pandemic restrictions have created significant volatility and disruption in the financial markets, and these conditions may require us to recognize an elevated level of other than temporary impairments on investment securities in our preliminary estimatesportfolio as issues of these securities are negatively impacted by the economic slowdown. Declines in fair value of investment securities in our portfolio could also reduce the unrealized gains reported as part of our consolidated comprehensive income (loss); and
We and our Bank are required to comply with minimum capital and leverage requirements. Our capital strategy is primarily to maintain capital levels through the effectCOVID-19 pandemic, and our Board of Directors could determine further clarification offuture reductions or foregoing dividends in order to maintain and/or strengthen our capital and liquidity position.

CorrectionDuring the second quarter of Prior Period Balancesfiscal year 2020, $40.0 million was deployed to repurchase and retire approximately 1.4 million shares of Company's common stock under the repurchase program authorized by the Board of Directors at an average price of $29.45. These purchases occurred prior to the onset of the COVID-19 pandemic. In early March 2020, the Company determined to indefinitely suspend additional buybacks within its remaining authorization to support the Federal Reserve Board in actions taken to moderate the impact of COVID-19 by maintaining strong capital levels and liquidity to support customers and other stakeholders.

The decline in adjusted net income in the current quarter was due to lower net interest income primarily attributable to a decline in loan and securities yields were outpaced by a decline in deposit and funding yields, particularly in March 2020 following the Federal Reserve's emergency rate cutting of 150 basis points. Our efficiency ratio was 63.5% and 45.6% for the same periods, an increase of $5.5 million, or 14.7%. Compared to the firstsecond quarter of fiscal year 2017, total revenue (non-FTE) for the first quarter of fiscal year 2018 grew by 4.2%, provision for loan2020 and lease losses were reduced 35.4% and noninterest expenses grew by 4.4%.

The decline in loans during the period was mainly attributable to a reduction in the agriculture segment of $126.9 million, or 6.3%, occurred primarily withinlargely due to a seasonal decrease related to customer tax planning and a number of relationships refinanced elsewhere, a reduction of $20.8 million, or 1.2%, in the commercial realnon-real estate ("CRE") segment of the loan portfolio which grew $170.9 million, including strong growth in owner-occupied CRE and construction loans.

The following tables present the distribution of average assets, liabilities and equity, interest income and resulting yields on average interest-earning assets, and interest expense and rates on average interest-bearing liabilities for the current and comparable three and six month periods, respectively. Loans on nonaccrual status that had interest accrued as of the date of nonaccrual isare immediately reversed as a reduction to interest income, while any interest subsequently recovered is recorded in the period of recovery. Tax-exempt loans and securities, totaling $735.7$743.0 million at DecemberMarch 31, 20172020 and $724.1$753.2 million at DecemberMarch 31, 2016,2019, are typically entered at lower interest rate arrangements than comparable non-exempt loans and securities. The amount of interest income reflected belowin the following table 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. Average net loan balances for the first Interest income on all loans decreased to $114.9 million in second quarter of fiscal year 2018 were $8.93 billion, representing a 3.3% increase compared to2020 from $124.9 million in the same period in fiscal year 2017.2019, a decrease of $10.0 million, or 8.0%. Interest income on all loans increaseddecreased to $109.2$235.8 million infor the first quartersix months of fiscal year 20182020, from $102.1$248.7 million in the same quarterperiod in fiscal year 2017, an increase2019, a decrease of $7.1$12.9 million, or 7.0%5.2%. The decreases in loan yields for both periods were primarily attributable to lower loan interest income driven by decreases of 39 and 28 basis points, respectively, between the two periods. For the three and six months ended March 31, 2020, interest income on ASC 310-30 loans, which are purchased credit impaired loans with a different income recognition model, decreased $0.5 million, or 27.2%, and $0.8 million, or 19.8%, respectively, primarily driven by runoff of the acquired loan portfolios.
Our yield on loans is affected by market interest rates, the level of adjustable-rate loan indices, interest rate floors and caps, customer repayment activity, the level of loans held for sale, portfolio mix, and the level of nonaccrual loans. The average tax equivalent yield on non-ASC 310-30 loans was 4.78%4.81% for the firstsecond quarter of fiscal year 2018, an increase2020, a decrease of 1338 basis points compared to the same quarterperiod in fiscal year 2017.2019. The average tax equivalent yield on non-ASC 310-30 loans was 4.89% for the first six months of fiscal year 2020, a decrease of 26 basis points compared to the same period in fiscal year 2019. Adjusted for the current realized gain (loss) on derivatives we use to manage interest rate risk on certain of our loans at fair value, which we believe represents the underlying economics of the transactions, the adjusted yield on non ASCnon-ASC 310-30 loans was 4.67%4.75% for the firstsecond quarter of fiscal year 2018,2020, a 2345 basis point an increasedecrease compared to the same quarterperiod in fiscal year 2017. In addition,2019. The adjusted yield on non-ASC 310-30 loans was 4.84% for the reduction in the magnitude of the tax equivalent adjustment driven by a lower statutory tax rate reduced each metric by approximately 2 basis points. Starting in first quartersix months of fiscal year 2016 and continuing through2020, a decrease of 32 basis points, compared to the first quarter of 2018 we have begunsame period in fiscal year 2019. For more information on our adjusted yield on non-ASC 310-30 loans, including a reconciliation to benefit from a period-over-period increase in LIBOR rates which has reduced the net cost of pay fixed, receive floating interest rate swaps the Company utilizes related to certain fixed rate loans and benchmark rate hikes which have raised interest rates on many of our floating and variable rate loans.most directly comparable GAAP financial measure, see "—Non-GAAP Financial Measures" section.
The average duration, net of interest rate swaps, of the loan portfolio was 1.21.5 years as of DecemberMarch 31, 2017.2020. Approximately 47%48%, or $4.33$4.64 billion, of the portfolio is comprised of fixed rate loans, of which $980.1$792.1 million of loans are fixed rate loans with an original term of 5 years or greater for which we have entered into equal and offsetting fixed-to-floating interest rate swaps. These loans effectively behave as floating rate loans. Of the remainingFor floating and variable rate loans in the portfolio, approximately 51%40% are indexed to Wall Street Journal Prime, 28%29% to 5-year Treasuries and the balance to various other indices. Approximately 2%22% of our total loans' rates are floored, with an average interest rate floor 71 bps119 basis points above market rates.rates as of March 31, 2020.
Loan-related fee income of $2.0$1.9 million is included in interest income for the second quarter of fiscal year 2020, compared to $1.6 million for the same period in fiscal year 2019. Loan-related fee income of $4.2 million is included in interest income for the first quartersix months of fiscal year 2018 and $1.42020, compared to $3.1 million for the same quarterperiod in fiscal year 2017.2019. In addition, certain fees collected at loan origination are considered to be a component of yield on the underlying loans and are deferred and recognized into income over the life of the loans. Amortization related to the FDIC indemnification assets of $1.0$0.4 million for both of the second quarters of fiscal years 2020 and 2019, respectively, and $0.6 million and $0.9 million for the first quartersix months of fiscal years 20182020 and 2017,2019, respectively, is included as a reduction to interest income.
Investment Portfolio. The carrying value of investment securities and FHLB stock was $1.41$2.03 billion as of DecemberMarch 31, 2017.2020.

The decreases for both periods were a result of decreasing interest rates in average interest-bearing deposits outstanding and increasing benchmark interest rates.the cost of deposits. Average deposit balances increased to $9.00 billion from $8.69$10.12 billion for the same periods,first six months of fiscal year 2020, from $10.08 billion for the comparable period in fiscal year 2019, an increase of $0.31 billion,$40.2 million, or 3.6%0.4%.

Oursame periods. The average balance forof FHLB advances and other borrowings was $519.6$539.4 million infor the current quarterfirst six months of fiscal year 2018, a $197.4 million reduction,2020 compared to $717.0$253.4 million infor the comparable quarter ofsame period in fiscal year 2017.

The average rate paid on FHLB advances is impacted by market rates and the various terms and repricing frequency of the specific outstanding borrowings in each year. The weighted average contractual rate paid on our FHLB advances was 1.57%1.46% and 0.83%2.85% at DecemberMarch 31, 20172020 and 2016,2019, respectively, and the average tenor was 314 and 6145 months for the same periods.
We must collateralize FHLB advances by pledging real estate loans or investments. We pledge more assets than required by our current level of borrowings in order to maintain additional borrowing capacity. Although we may substitute other loans for such pledged loans, we are restricted in our ability to sell or otherwise pledge these loans without substituting collateral or prepaying a portion of the FHLB advances. At DecemberMarch 31, 2017,2020, we had pledged $3.77$4.11 billion of loans to the FHLB, against which we had borrowed $721.0$800.0 million.

The weighted average contractual rate on outstanding subordinated notes was 4.88% at both DecemberMarch 31, 20172020 and September 30, 2017.
Securities Sold Under Agreements to Repurchase. Securities sold under agreements to repurchase represent retail repurchase agreements with customers and represent a small portion of our overall funding profile. The interest expense associated with this class of liabilities remained largely consistent between the current quarter and comparable quarter.2019.
Rate and Volume Variances
Net interest income is affected by changes in both volume and interest rates. Volume changes are caused by increases or decreases during the year in the level of average interest-earning assets and average interest-bearing liabilities. Rate changes result from increases or decreases in the yields earned on assets or the rates paid on liabilities.
The following table presents for the current and comparable quarter and six months periods a summary of the changes in interest income and interest expense on a tax equivalent basis resulting from changes in the volume of average asset and liability balances and changes in the average yields or rates compared with the preceding fiscal year. If significant, the change in interest income or interest expense due to both volume and rate has been prorated between the volume and the rate variances based on the dollar amount of each variance.

Provision for Loan and Lease Losses
We recognized provision for loan and lease losses of $4.6$71.8 million for the firstsecond quarter of fiscal year 20182020 compared to a provision for loan and lease losses of $7.0$7.7 million for the comparable quarterperiod in fiscal year 2017, a decrease2019, an increase of $2.4$64.1 million, between the periods or 35.4%. The decrease in provisiondue to incurred loss resulting from the COVID-19 pandemic. This increase did not contemplate the potential impact of CECL implementation, which is effective for the Company October 1, 2020. Provision for loan and lease losses was driven primarily by lower specific reserves in the agriculture and commercial non-real estate segments of the loan portfolio. We recorded a $0.1$79.9 million net improvement in provision for ASC 310-30 loans for the first quartersix months of fiscal year 2018,2020, compared to a net impairment in provision of $0.1$12.9 million for the comparable quarterperiod in fiscal year 2017.2019, an increase of $67.0 million between the periods. See "—Overview—Impact and Response to COVID-19 Pandemic" section in this document for further discussion on the increase in provision for loan and lease losses for both periods.

Total Credit-Related Charges
In addition to the lower provision for loan losses we incurred during the current fiscal quarter of 2018 compared to the same quarter in 2017, we recognized other credit-related charges. We believe that the following table, which summarizes each component of the total credit-related charges incurred during the current prior and comparable quarter,quarters and six month periods, is helpful to understanding the overall impact on our quarterly results of operations. Net other repossessed property charges includes other repossessed property operating costs, valuation adjustments and (loss) gain on sale of other repossessed properties, each of which entered other repossessed property as a result of the former borrower failing to perform on a loan obligation. Reversal of interest income on nonaccrual loans occurs when we become aware that a loan, for which we had been recognizing interest income, will no longer be able to perform according to the terms and conditions of the loan agreement, including repayment of interest owed to us, while a recovery of interest income on nonaccrual loans occurs when we receive repayment of interest owed to us. Loan fair value adjustments related to credit relate to the portion of our loan portfolio for which we have elected the fair value option; these amounts reflect the portion of the fair value adjustment related to expected credit losses in the portfolio.portfolio of loans carried at fair value.

In determining the credit related charges attributable to the COVID-19 pandemic, we considered the impact upon our loan portfolio. Industries such as oil & energy, hotels & resorts, restaurants, retail malls, airlines and others have been cited as being at risk for significant revenue loss. Within our portfolio at March 31, 2020, $1.14 billion, or 11.8% relates to hotels & resorts, $109.8 million, or 1.1% relates to restaurants, with exposure in such other identified industries being immaterial. At this time it is difficult to determine ultimate impact upon our portfolio, but we are of the view the credit-related adjustments reflect the best estimate of incurred losses in our portfolio as of March 31, 2020.

Our noninterest income is comprised of the various fees we charge our customers for products and services we provide and the impact of changes in fair value of loans for which we have elected the fair value treatment and realized and unrealized gains (losses) on the related interest rate swaps we utilize to manage interest rate risk on these loans. While we are required under U.S. GAAP to present both components within total noninterest income, we believe it is helpful to analyze the two broader components of noninterest income separately to better understand the underlying performance of the business.
Noninterest income was $16.7$(0.1) million for the second quarter of fiscal year 2020 compared to $18.2 million for the same period in fiscal year 2019, a decrease of $18.3 million, or 100.5%. Noninterest income was $15.7 million for the first quartersix months of fiscal year 2018,2020 compared to $15.7$34.9 million for the comparable quartersame period in fiscal year 2017, an increase2019, a decrease of $1.0$19.2 million, or 6.5%55.2%. Significant components of noninterest income are described in further detail below.
Product and Service Fees. We recognized $18.1$14.6 million of noninterest income related to product and service fees in the second quarter of fiscal year 2020, a decrease of $0.6 million, or 4.2%, compared to the same period in fiscal year 2019. We recognized $31.7 million of noninterest income related to product and service fees in the first quartersix months of fiscal year 2018, a decrease2020, an increase of $2.6$0.7 million, or 12.4%2.2%, compared to the same quarterperiod in fiscal year 2017.2019. The decreasedecreases for both periods was primarily attributablerelated to a $1.0 million decreasedeclines in mortgage banking income, a $0.8 million decrease in other income, and a $0.7transaction activity from COVID-19 pandemic impacts.

million decrease in service charges and other fees, which reflected a modest decrease primarily driven by the full quarter impact of the "Durbin Amendment" limit on debit card interchange income that became effective in July 2017.
Loans at fair value and related derivatives. As discussed in "—Analysis of Financial Condition—Derivatives," changes in the fair value of loans for which we have elected the fair value treatment and realized and unrealized gains and losses on the related derivatives are recognized within noninterest income. For the firstsecond quarter of fiscal year 2018,2020, these items accounted for $(1.4)$(14.7) million of noninterest income compared to $(5.0)$3.0 million of noninterest income for the same quarterperiod in fiscal year 2017.2019. The change was driven by a net favorable change in the credit adjustment of $1.6$1.7 million combined with a $2.0 million reductionincrease in the current cost of interest rate swaps driven bydue to changes in the interest rate environment.environment and a $1.1 million decrease in swap fees, and a net unfavorable change in the credit risk adjustment of $14.9 million, $10.4 million of which was related to the COVID-19 pandemic impact on loan fair value adjustment related to credit. For the first six months of fiscal year 2020, these items accounted for $(16.1) million of noninterest income compared to $3.9 million of noninterest income for the same period in fiscal year 2019. The change was driven by a $2.6 million increase in the current cost of interest rate swaps due to changes in the interest rate environment and $3.0 million decrease in swap fees, and a net unfavorable change in credit risk adjustment of $14.5 million, $10.4 million of which was related to the COVID-19 pandemic impact on loan fair value adjustment related to credit. We believe that the current realized loss on the derivatives economically offsets the interest income earned on the related loans; weloans. We present elsewhere the adjusted net interest income and adjusted net interest margin reflecting the metrics we use to manage the business.

Our noninterest expense consists primarily of salaries and employee benefits, data processing and communication, occupancy expenses,and equipment, professional fees communication expenses, advertising and acquisitionnet loss on repossessed property, goodwill and intangible assets impairment and other related expenses. Noninterest expense was $54.9$808.5 million in the firstsecond quarter of fiscal year 20182020 and $865.4 million for the first six months of fiscal year 2020. Included within these amounts are goodwill impairment of $740.6 million, impairment of certain intangible assets of $1.8 million, and the COVID-19 pandemic credit related charges of a $3.3 million charge for one OREO hotel property negatively impacted by COVID-19 travel restrictions and $0.4 million increase in reserve for unfunded commitments. Excluding these items, noninterest expense was $62.3 million for the second quarter of fiscal year 2020, compared to $52.5$56.6 million for the same quarterperiod in fiscal year 2017,2019, an increase of $2.3$5.8 million, or 4.4%. Included in noninterest expense10.2%, and $119.3 million for the first quartersix months of fiscal year 2017 was $0.72020, compared to $113.7 million for the same period in fiscal year 2019, an increase of non-recurring acquisitions expenses; absent this reduction, total noninterest expense increased by $3.0$5.6 million, or 5.9%, over the same period. This increase was primarily attributable to a $1.4 million increase in professional fees primarily4.9%. The remaining increases were driven by an increase in our FDIC assessment, a $1.2 million increase in salaries and employee benefits related to annual merit increases effective in January, a one-time bonus payment to retail staff of $0.5 million and a $1.0 million increase in other expenses, partially offset by a decrease of $0.4 million in net loss recognizedelevated legal and administrative costs on repossessed property and other related expenses.OREO assets.
Our efficiency ratio was 45.8%63.5% and 45.1%45.6% for the three monthsecond quarter of fiscal years 2020 and 2019, respectively and 54.1% and 45.8% for the first six months of fiscal years 2020 and 2019, respectively. The increases for both periods ending December 31, 2017were mainly due to the decrease in net revenues attributable to emergency rate cuts and 2016, respectively.decreased deposit service charges from lower account activity combined with increased expense results from both one-off and recurring costs. For more information on our efficiency ratio, including a reconciliation to the most directly comparable GAAP financial measures, see "—Non-GAAP Financial Measures" section.
Provision for Income Taxes
The provision for income taxes varies due to the amount of taxable income, the level and effectiveness of tax-advantaged assets and tax credit funds and the rates charged by federal and state authorities. The provisionbenefit for income taxes of $28.6$37.7 million for the firstsecond quarter of fiscal year 20182020 represents an effective tax rate of 49.5%,4.8% compared to a provision of $16.1$12.9 million, or an effective tax rate of 30.3%22.5%, for the comparable quarter.

During the first quartersix months of fiscal year 2018,2020, total loans increaseddecreased by 2.2%0.1%, or $196.8 million.$13.5 million, compared to September 30, 2019. The growthnet loan reduction was primarily focused in CRE and agriculture segments of the loan portfolio, which grew $170.9 million and $55.2 million, respectively, offset bymainly attributable to a reduction in the agriculture segment of $23.2$126.9 million, or 6.3%, a reduction in the commercial non-real estate loans.segment of $20.8 million, or 1.2%, offset by an increase in the CRE segment of $130.4 million, or 2.6%. The decrease in the agriculture segment was largely due to a seasonal decrease related to customer tax planning and a number of relationships financed elsewhere. The decrease in the commercial non-real estate segment was due to disbursement transaction timing within our mortgage warehouse lending to independent mortgage originators. The increase in the CRE segment was attributable to growth from construction drawdowns and new relationships across the footprint. Over the same time period, residential real estate, consumer and other loan balances remained generally stable.

Commercial Real Estate. CRE includes owner-occupied CRE, non-owner-occupied CRE, construction and development lending, and multi-family residential real estate. While CRE lending will remainis a significant component of our overall loan portfolio, we are committed to managing our exposure to riskier construction and development lending specifically, and to CRE lending in general, by targeting relationships with sound management and financials, which are priced to reflect the amount of risk we accept as the lender.
Agriculture. Agriculture loans include farm operating loans and loans collateralized by farm land. According to the American Banker's Association, at September 30, 2017,December 31, 2019, we were ranked the sixth-largestfifth-largest farm lender bank in the United States measured by total dollar volume of farm loans. We consider agriculture lending one of our core competencies.lending areas. We target a 20% to 30% portfolio composition for agriculture loans not to exceed 225% of total capital 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. WhileOver recent years, our borrowers have experienced volatile commodity prices, over recent years, we believe there continuesand the adverse effects of recently imposed and proposed tariffs on the export of agricultural products, effects of waivers of the amount of ethanol to typically be strong secondary

indirectly and adversely impact other lending categories including commercial non-real estate, CRE, residential real estate and consumer.consumer, we believe there continues to typically be strong secondary sources of repayment for the agriculture loan portfolio.
Commercial Non-Real Estate. Commercial non-real estate, or business lending, represents one of our core competencies. We believe that providing a tailored range of integrated products and services, including lending, to small- and medium-enterprise customers is the business at which we excel and through which we can generate favorable returns for our stockholders. We offer a number of different products including working capital and other shorter-term lines of credit, fixed-rate loans and variable rate loans with interest rate swaps over a wide range of terms, and variable-rate loans with varying terms. Our bank's direct exposure to energy-related borrowers is less than 1.4% of total loans.
Residential Real Estate. Residential real estate lending reflects 1-to-4-family real estate construction loans, closed-end first-lien mortgages (primarily single-family long-term first mortgages resulting from acquisitions of other banks), closed-end junior-lien mortgages and home equity lines of credit, or HELOCs. Our closed-end first-lien mortgages include a small percentage of single-family first mortgages that we originate and do not subsequently sell into the secondary market, including some jumbo products, adjustable-rate mortgages and rural home mortgages. Conversely, a large percentage of our total single-family first mortgage originations are sold into the secondary market in order to meet our interest rate risk management objectives.
Consumer. Our consumer lending offering comprises a relatively small portion of our total loan portfolio, and predominantly reflects small-balance secured and unsecured products marketed by our retail branches.
Other Lending. Other lending includes all other loan relationships that do not fit within the categories above, primarily consumer and commercial credit cards, customer deposit account overdrafts, and lease receivables.

Other Repossessed Property
In the normal course of business, we obtain title to parcels of real estate and other assets when borrowers are unable to meet their contractual obligations and we initiate foreclosure proceedings, or via deed in lieu of foreclosure actions. Other repossessed property assets are considered nonperforming assets. When we obtain title to an asset, we evaluate how best to maintain and protect our interest in the property and seek to liquidate the asset at an acceptable price in a timely manner. Our total other repossessed property carrying value was $10.5$27.3 million as of DecemberMarch 31, 2017, an increase2020, a decrease of $1.5$9.5 million, or 16.7%25.8%, compared to September 30, 2017. 2019, due primarily to one large relationship liquidation and the write down of the value of a hotel property negatively impacted by COVID-19 travel restrictions.

We have historically invested excess deposits in high-quality, liquid investment securities including residential agency mortgage-backed securities and, to a lesser extent, U.S. Treasury securities, corporate debt securities and securities issued by U.S. states and political subdivisions. Our investment portfolio serves as a means to collateralize FHLB borrowings and public funds deposits, to earn net spread income on excess deposits and to maintain liquidity and balance interest rate risk. Since September 30, 2017, the fair value of the portfolio has decreased by $1.3 million, or 0.1%.
The following table presents the aggregate amortized cost of each investment category of the investment portfolio and the weighted average yield for each investment category for each maturity period held at December 31, 2017. Maturities of mortgage-backed securities may differ from contractual maturities because the mortgages underlying the securities may be called or prepaid without any penalties. The weighted-average yield ("WA Yield") on these assets is presented below based on the contractual rate, as opposed to a tax equivalent yield concept.

Asset Quality
We place an asset on nonaccrual status when any installmentmanagement believes, after considering collection efforts and other factors, the borrower's condition is such that collection of principal or interest is more thandoubtful, which is generally 90 days past duedue. If a borrower has failed to comply with the original contractual terms, further action may be required, including a downgrade in the risk rating, movement to nonaccrual status, a charge-off or earlier when management determines the ultimateestablishment of a specific reserve. If there is a collateral shortfall, we generally work with the borrower for a principal reduction, pledge of additional collateral or guarantee. If these alternatives are not available, we engage in formal collection of all contractually due principal or interest to be unlikely.activities. Restructured loans for which we grant payment or significant interest rate concessions are placed on nonaccrual status until collectability improves and a satisfactory payment history is established, generally by the receipt of at least six consecutive payments. Our collection policies related to delinquent and charged-off loans are highly focused on individual relationships, and we believe that these policies are in compliance with all applicable laws and regulations.
The following table presents the dollar amount of nonaccrual loans, other repossessed property, restructured performing loans and accruing loans over 90 days past due, at the end of the dates indicated. We entered into a non-commercial loss-sharing agreement with the FDIC related to certain assets (loans and other repossessed property) acquired from TierOne Bank on June 4, 2010. Loans covered by a FDIC loss-sharing agreementsagreement are generally pooled with other similar loans and are accreting purchase discount into income each period. Subject to compliance with the applicable loss-sharing agreement, we are indemnified by the FDIC at a rate of 80% for any future credit losses onfor single-family real estate loans and other repossessed property covered by athe FDIC loss-sharing agreement through June 4, 2020 for single-family real estate loans.2020.

2019.
We recognized approximately $0.2$1.0 million of interest income on loans that were on nonaccrual for the first quartersix months of fiscal year 2018.2020. Excluding loans covered by the FDIC non-commercial loss-sharing agreements,agreement, we had average nonaccrual loans (calculated as a two-point average) of $138.3$158.0 million outstanding during the first quartersix months of fiscal year 2018.2020. Based on the average loan portfolio yield for these loans for the first quartersix months of fiscal year 2018,2020, we estimate that interest income would have been $1.7$3.9 million higher during this period had these loans been accruing.
We consistently monitor all loans internally rated “watch”"watch" or worse because that rating indicates we have identified some potential weakness emerging; but loans rated “watch”"watch" will not necessarily become problem loans or become impaired. Aside from the loans on the watch list, we do not believe we have any potential problem loans that are not already identified as nonaccrual, past due or restructured as it is our policy to promptly reclassify loans as soon as we become aware of doubts as to the borrowers’ ability to meet repayment terms.
When we grant concessions to borrowers that we would not otherwise grant if not for the borrowers’ financial difficulties, such as reduced interest rates or extensions of loan periods, we consider these modifications troubled debt restructurings ("TDRs").TDRs.

Total nonperforming TDRs decreased $7.3$2.0 million, or 10.2%6.8%, compared to September 30, 20172019 primarily due mainly to partial charge offs on two relationships and a substantial paydown from one relationshippaydowns in ourthe agriculture portfolio during the quarter.portfolio.
We entered into loss-sharing agreements with the FDIC related to certain assets (loans and other repossessed property) acquired from TierOne Bank on June 4, 2010. We are generally indemnified by the FDIC at a rate of 80% for any future credit losses through June 4, 2020 for single-family real estate loans and other repossessed property. Our commercial loss-sharing agreement with the FDIC has expired.

Allowance for Loan and Lease Losses
We establish an allowance for the inherent risk of probable losses within our loan portfolio. The allowance for loan and lease losses is management’s best estimate of probable credit losses that are incurred in the loan portfolio. We determine the allowance for loan and lease losses based on an ongoing evaluation, driven primarily by monitoring changes in loan risk grades, delinquencies and other credit risk indicators, which is an inherently subjective process. We consider the uncertainty related to certain industry sectors and the extent of credit exposure to specific borrowers within the portfolio. In addition, we consider concentration risks associated with the various loan portfolios, and current economic conditions and other environmental factors that might impact the portfolio. All of these estimates are susceptible to significant change. Changes to the allowance for loan and lease losses are made by charges to the provision for loan and lease losses. Loans deemed to be uncollectible are charged off against the allowance for loan and lease losses. Recoveries of amounts previously charged-off are credited to the allowance for loan and lease losses.
Our allowance for loan and lease losses consists of two components. For non-impaired loans, we calculate a weighted average loss ratio of 12-, 36- and 60-month historical realized losses by collateral type; adjust as necessary for our interpretation of current economic conditions, environmental factors and current portfolio trends including credit quality, concentrations, aging of the portfolio and/or significant policy and underwriting changes not entirely covered by the calculated historical loss rates; and apply the loss rates to outstanding loan balances in each collateral category. We calculate the weighted average ratio of 12-, 36- and 60-month historical realized losses for each collateral type by dividing the average net annual charge-offs by the average outstanding loans of such type subject to the calculation for each of the 12-, 36- and 60-month periods, then averaging those three results. For impaired loans, we estimate our exposure for each individual relationship, given the current payment status of the loan and the value of the underlying collateral as supported by third party appraisals, broker’s price opinions, and/or the borrower’s financial statements and internal valuation assessments, each adjusted for liquidation costs. Any shortfall between the liquidation value of the underlying collateral and the recorded investment value of the loan is considered the required specific reserve amount. Actual losses in any period may exceed allowance amounts. We evaluate and adjust our allowance for loan and lease losses, and the allocation of the allowance between loan categories, each month.

In the first quartersix months of fiscal year 2018,2020, net charge-offs were $4.0$14.7 million, or 0.18%0.31%, of average total loans on an annualized basis, comprised of $4.6$17.0 million of charge-offs and $0.6$2.3 million of recoveries. The charge-offs were concentrated in the agriculture and commercial non-real estate segments in the loan portfolio. For fiscal year 2017,2019, net charge-offs were $22.7$34.7 million, or 0.26%0.36%, of average total loans.
At DecemberMarch 31, 2017,2020, the allowance for loan and lease losses was 0.70%1.40% of our total loan portfolio, a 167 basis point decreaseincrease, compared to 0.71%0.73% at September 30, 2017.2019. The balance of the ALLL increased to $64.0$136.0 million from $63.5$70.8 million over the same period.period due to incurred loss resulting from COVID-19 pandemic. This increase did not contemplate the potential impact of CECL implementation, which is effective for the Company October 1, 2020. In determining the credit related charges attributable to the COVID-19 pandemic, we considered the impact upon our loan portfolio. Industries such as oil & energy, hotels & resorts, restaurants, retail malls, airlines and others have been cited as being at risk for significant revenue loss. Within our portfolio, $1.14 billion, or 11.8% relates to hotels & resorts, $109.8 million, or 1.1% relates to restaurants, with exposure in such other identified industries being immaterial. At this time it is difficult to determine ultimate impact upon our portfolio, but we are of the view the credit-related adjustments reflect the best estimate of incurred losses in our portfolio as of March 31, 2020.

Additionally, a portion of our loans which are carried at fair value, totaling $980.1$792.1 million at DecemberMarch 31, 20172020 and $1.02 billion$813.0 million at September 30, 2017,2019, respectively, have no associated allowance for loan and lease losses, but rather have a fair value adjustment related to credit risk included within their carrying value, thus driving the overall ratio of allowance for loan and lease losses to total loans lower. The amount of fair value adjustment related to credit risk on these loans was $6.2$16.7 million and $8.3$6.8 million at DecemberMarch 31, 20172020 and September 30, 2017,2019, respectively, or 0.07%0.17% and 0.09%0.07% of total loans, respectively.

Management will continue to evaluate the loan portfolio and assess economic conditions in order to determine future allowance levels and the amount of loan and lease loss provisions. We review the appropriateness of our allowance for loan and lease losses on a monthly basis. Management monitors closely all past due and restructured loans in assessing the appropriateness of its allowance for loan and lease losses. In addition, we follow procedures for reviewing and grading all substantial commercial and agriculture relationships at least annually. Based predominantly upon the review and grading process, we determine the appropriate level of the allowance in response to our assessment of the probable risk of loss inherent in our loan portfolio. Management makes additional loan and lease loss provisions when the results of itsour problem loan assessment methodology or overall allowance testing of appropriateness test indicateindicates additional provisions are required.
The review of problem loans is an ongoing process during which management may determine that additional charge-offs are required or additional loans should be placed on nonaccrual status. We have also recorded an allowance for unfunded lending-related commitments that represents our estimate of incurred losses on the portion of lending commitments that borrowers have not advanced. The balance of the allowance for unfunded lending-related commitments was $1.1 million and $0.5 million at DecemberMarch 31, 20172020 and September 30, 2017.2019, respectively, and is recorded in accrued expenses and other liabilities in the consolidated balance sheet.

Declines in the fair value of investment securities available for sale that are deemed to be other-than-temporary are recognized in earnings as a realized loss, and a new cost basis for the securities is established. In evaluating other-than-temporary impairment, we consider the length of time and extent to which the fair value has been less than amortized cost, the financial condition and near-term prospects of the issuer, and our intent and ability to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value in the near term. Declines in the fair value of debt securities below amortized cost are deemed to be other-than-temporary in circumstances where: (1) we have the intent to sell a security; (2) it is more-likely-than-not that we will be required to sell the security before recovery of its amortized cost basis; or (3) we do not expect to recover the entire amortized cost basis of the security. If we intend to sell a security or if it is more-likely-than-not that we will be required to sell the security before recovery, an other-than-temporary impairment loss is recognized in earnings equal to the difference between the security’s amortized cost basis and its fair value. If we do not intend to sell the security or it is not more-likely-than-not that it will be required to sell the security before recovery, the other-than-temporary impairment write-down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in other comprehensive income (loss).
Deposits
We obtain funds from depositors by offering consumer and business demand deposit accounts, money market accounts, NOW accounts, savingsinterest-bearing accounts and term time deposits. At DecemberMarch 31, 20172020 and September 30, 2017,2019, our total deposits were $9.02$10.18 billion and $8.98$10.30 billion, respectively, representing a decrease of $121.2 million, or 1.2%, due to a reduction in the use of brokered deposits partially offset by an increase of 0.5%, which was primarily spread across commercial and public deposit accounts.in business deposits. Our accounts are federally insured by the FDIC up to the legal maximum. We have significantly shifted the composition of our deposit portfolio away from time deposits toward demand, NOW, money market and savings accounts in recent years.

Derivatives
Beginning in the second quarter of fiscal year 2018, we entered into RPAs with some of our derivative counterparties to assume the credit exposure related to interest rate derivative contracts. Our loan customer enters into an interest rate swap directly with a derivative counterparty and we agree through an RPA to take on the counterparty's risk of loss on the interest rate swap due to a default by the customer. The notional amounts of RPAs sold were $78.2 million and $56.8 million as of March 31, 2020 and September 30, 2019, respectively. Assuming all underlying loan customers defaulted on their obligation to perform under the interest rate swap with a derivative counterparty, the exposure from these RPAs would be $0.6 million and $0.1 million at March 31, 2020 and September 30, 2019, respectively, based on the fair value of the underlying swaps.
In 2017, we began a new program of selling interest swaps directly to customers. These interest rate swaps sales are used to enable customers to achieve a long-term fixed rate by selling the customer a long-term variable rate loan indexed to LIBOR plus a credit spread whereby the Bank enters into an interest rate swap with our customer where the customer pays a fixed rate of interest set at the time of origination on the interest rate swap and then the customer receives a floating rate equal to the rate paid on the loan, thus resulting in a fixed rate of interest over the life of the interest rate swap. We then enter into a mirrored interest rate swap with a swap dealer where we pay and receive the same fixed and floating rate as we pay and receive from the interest rate swap we have with our customer. As the interest paid and received by us on the two swaps net to zero, we are left with the variable rate of the long-term loan.

Prior to 2017 we entered into fixed-rate loans having original maturities of 5 years or greater (typically between 5 and 15 years) with certain of our commercial and agribusinessagri-business banking customers to assist them in facilitating their risk management strategies. We mitigated our interest rate risk associated with certain of these loans by entering into equal and offsetting fixed-to-floating interest rate swap agreements for these loans with swap counterparties. We elected to account for the loans at fair value under ASC 825, Fair 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 hedgesinterest rate swaps 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 hedgedfair value option 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 hedginginterest rate swap activity resulting from loan customer prepayments (partial or full) to the customer.

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 U.S. 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:

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

62-63-





Our liquidity risk is managed through a comprehensive framework of policies and limits overseen by our bank’sBank’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.Bank. We also monitor our bank’sBank’s deposit to loan ratio to ensure high quality funding is available to support our strategic lending growth objectives, and have internal management targets for the FDIC’s liquidity ratio, net short-term non-core funding dependence ratio and non-core liabilities to total assets ratio. The results of these measures and analyses are incorporated into our contingency funding plan, which provides the basis for the identification of our liquidity needs. We also acquire brokered deposits when the cost of funds is advantageous to other funding sources.
Great Western Bancorp, Inc. Our primary source of liquidity is cash obtained from dividends paid by our bank.Bank. We primarily use our cash for the payment of dividends, when and if declared by our Board of Directors, and the payment of interest on our outstanding junior subordinated debentures and subordinated notes. We also use cash, as necessary, to satisfy the needs of our bankBank through equity contributions and for acquisitions. At DecemberMarch 31, 2017,2020, our holding company had $53.4$31.4 million of cash. During the firstsecond quarter of fiscal year 2018,2020, we declared and paid a dividend of $0.20$0.30 per common share. The outstanding amountsamount under our revolving line of credit with a large retail bank and our private placement subordinated capital notes together totaledwas $35.0 million at DecemberMarch 31, 2017.2020. Our management believes that the sources of available liquidity are adequate to meet all reasonably foreseeable short-term and intermediate-term demands. We may consider raising additional capital in public or private offerings of debt or equity securities. To this end, in August 2018 we filed a shelf registration statement with the SEC registering an indeterminate amount of our common stock, debt securities and other securities which we may decide to issue in the future. The specific terms of any shares or other securities we choose to issue will be based on current market conditions and will be described in a supplement to the prospectus contained in the shelf registration statement.
Great Western Bank. Our bankBank 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.funding. At DecemberMarch 31, 2017,2020, our bankBank had cash of $297.6$347.5 million and $1.37$1.99 billion of highly-liquid securities held in our investment portfolio, of which $990.6$918.8 million were pledged as collateral on public deposits, securities sold under agreements to repurchase, and for other purposes as required or permitted by law. The balance could be sold to meet liquidity requirements. Our bankBank had $721.0$800.0 million in FHLB borrowings at DecemberMarch 31, 2017,2020, with additional available lines of $1.40$1.46 billion. Our bankBank also had an additional borrowing capacity of $1.69$1.23 billion with the FRB Discount Window. Our bankBank 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 DecemberMarch 31, 2017,2020, we had a total of $2.57$2.11 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’sBank’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 bankBank must comply with the capital requirements established by the FDIC. The current risk-based guidelines applicable to us and our bankBank are based on the Basel III framework, as implemented by the federal bank regulators.

Non-GAAP Financial Measures
We rely on certain non-GAAP financial measures in making financial and operational decisions about our business. We believe that each of the non-GAAP financial measures presented is helpful in highlighting trends in our business, financial condition and results of operations which might not otherwise be apparent when relying solely on our financial results calculated in accordance with U.S. generally accepted accounting principles, or GAAP. We disclose net interest income and related ratios and analysis on a taxable-equivalent basis, which may also be considered non-GAAP financial measures. We believe this presentation to be the preferred industry measurement of net interest income as it provides a relevant comparison of net interest income arising from taxable and tax-exempt sources. In addition, certain performance measures, including the efficiency ratio and net interest margin utilize net interest income on a taxable-equivalent basis.
In particular, we evaluate our profitability and performance based on our adjusted net income, adjusted earnings per common share, tangible net income and return on average tangible common equity. Our adjusted net income and adjusted earnings per common share exclude the after-tax effect of items with a significant impact to net income that we do not believe to be recurring in nature, (e.g., one-time acquisition expenses as well as the effectCOVID-19 impact on credit and other related charges and the impairment of revaluation of deferred taxes)goodwill and certain intangible assets). Our tangible net income and return on average tangible common equity exclude the effects of amortization expense relating to intangible assets and related tax effects from the acquisition of us by NAB and our acquisitions of other institutions. We believe these measures help highlight trends associated with our financial condition and results of operations by providing net income and return information excluding significant nonrecurring items (for adjusted net income and adjusted earnings per common share) and based on our cash payments and receipts during the applicable period (for tangible net income and return on average tangible common equity).
We also evaluate our profitability and performance based on our adjusted net interest income, adjusted net interest margin, adjusted interest income on non ASCnon-ASC 310-30 loans and adjusted yield on non ASCnon-ASC 310-30 loans. We adjust each of these four measures to include the current realized gain (loss) of derivatives we use to manage interest rate risk on certain of our loans, which we believe economically offsets the interest income earned on the loans. Similarly, we evaluate our operational efficiency based on our efficiency ratio, which excludes the effect of amortization of core deposit and other intangibles (a non-cash expense item) and includes the tax benefit associated with our tax-advantaged loans.
65-


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

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

As of DecemberMarch 31, 2017,2020, there have been no material changes in the quantitative and qualitative information about market risk provided pursuant to Item 305 of Regulation S-K as presented in our Annual Report on Form 10-K for the fiscal year ended September 30, 2017.2019.
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 monthlyregularly 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 DecemberMarch 31, 20172020 are presented in the following table. The projections assume (1) immediate, parallel shifts downward of the yield curve of 100 and 200 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 and 200 basis points over 12 months and gradual shifts upward of 100, 200, 300 and 400 basis points over 12 months. In the current interest rate environment, a downward shift of the yield curve of 200, 300 and 400 basis points does not provide us with meaningfulrealistic results. In a downward parallel shift of the yield curve, interest rates at the short-end of the yield curve are not modeled to decline any further than 0%. For the immediate-shift scenarios, we assume short-term rates follow a forward yield curve throughout the forecast period that is dictated by the instantaneously shocked yield curve from the as of date. In the gradual-shift scenarios, we take each rate across the yield curve from the as of date and shock it by 1/12th of the total change in rates each month for twelve months.

We primarily use interest rate swaps to ensure that long-term fixed-rate loans are effectively re-priced as short-term rates change, which we believe would allow us to achieve these results. The results of this simulation analysis are hypothetical, and a variety of factors might cause actual results to differ substantially from what is depicted. For example, if the timing and magnitude of interest rate changes differ from those projected, our net interest income might vary significantly. Non-parallel yield curve shifts, such as a flattening or steepening of the yield curve or changes in interest rate spreads, would also cause our net interest income to be different from that depicted. An increasing interest rate environment could reduce projected net interest income if deposits and other short-term liabilities re-price faster than expected or faster than our assets re-price. Actual results could differ from those projected if we grow assets and liabilities faster or slower than estimated, if we experience a net outflow of deposit liabilities or if our mix of assets and liabilities otherwise changes. Actual results could also differ from those projected if we experience substantially different repayment speeds in our loan portfolio than those assumed in the simulation model. Finally, these simulation results do not contemplate all the actions that we may undertake in response to potential or actual changes in interest rates, such as changes to our loan, investment, deposit, funding or hedginginterest rate swap strategies.

ITEM 1.LEGAL PROCEEDINGS
ITEM 1. LEGAL PROCEEDINGS
From time to time, we are a party to various litigation and regulatory matters incidental to the conduct of our business. We establish reserves for such matters when potential losses become probable and can be reasonably estimated. We believe the ultimate resolution of existing litigation and regulatory matters will not have a material adverse effect on our financial condition, results of operations or cash flows. However, changes in circumstances or additional information could result in additional accruals or resolution of these matters in excess of established accruals, which could adversely affect our financial condition, results of operations or cash flows, potentially materially.

ITEM 1A.RISK FACTORS


ITEM 1A. RISK FACTORS
There have been no material changesare certain risks and uncertainties in the risk factors described inour business that could cause our actual results to differ materially from those anticipated. See "Part I, Item 1A1A. Risk Factors" of ourthe Annual Report on Form 10-K of Great Western Bancorp, Inc., for the fiscal year ended September 30, 2017.2019 (the “2019 Form 10-K”), which includes a detailed discussion of our risk factors. Other than as noted below, our risk factors have not changed significantly from those disclosed in our 2019 Form 10-K. These risk factors should be read carefully in connection with evaluating our business and in connection with the forward-looking statements and other information contained in this Quarterly Report on Form 10-Q. Any of the risks described in our 2019 Form 10-K could materially affect our business, consolidated financial condition or future results of operations and the actual outcome of matters as to which forward-looking statements are made. The risk factors described in our 2019 Form 10-K are not the only risks we face. Additional risks and uncertainties not currently known to us, or that we currently deem to be immaterial, also may materially adversely affect our business, consolidated financial condition and/or future results of operations.
The outbreak of the COVID-19 pandemic has caused a significant global economic downturn which has adversely affected, and is expected to continue to adversely affect, our business and results of operations, and the future impacts of the COVID-19 pandemic on the global economy and our business, results of operations and financial condition remain uncertain.
ITEM 2.UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
Health epidemics or pandemics (or expectations about them) such as COVID-19, have destabilized financial markets in which we operate. COVID-19, which has been identified as a pandemic by the World Health Organization, is causing worldwide concern and economic disruption. The ongoing COVID-19 global and national health emergency has caused and will likely continue to cause significant disruption in the international and United States economies and financial markets, including the capital markets, as well as locally in our markets. There are cases of COVID-19 in all of our states in which we have branches. The ultimate extent of the impact on our business, financial condition, liquidity, results of operations and prospects will depend on future developments, which are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of the pandemic, and actions taken to contain or prevent further spread. These and other potential impacts of epidemics, pandemics or other outbreaks of an illness, disease or virus could therefore materially and adversely affect our business, revenue, operations, financial condition, liquidity, results of operations and prospects. If the response to contain COVID-19 is unsuccessful, material adverse effects may be exacerbated.
COVID-19 and its associated impacts on economic activities have had, are currently having and may for some time continue to have a destabilizing effect on financial markets and economic activity and have coincided with heightened volatility and significant disruption in financial markets and economy in the United States and worldwide, which could have a material adverse effect on our business, cash flows, business and consumer confidence, consolidated financial condition, results of operations, profitability, and growth asset quality. The full extent of the impact of COVID-19 is currently uncertain, cannot be predicted and will depend on certain developments, including, among others, governmental, regulatory and private sector actions and responses. Market interest rates have declined significantly. We expect that these reductions in interest rates, especially if prolonged, could adversely affect our net interest income, margins and our profitability. Our assets and liabilities may be significantly impacted by changes in interest rates.
Our business is dependent upon the willingness and ability of our customers to conduct banking and other financial transactions. The spread of COVID-19 could disrupt the business, activities, and operations of our customers, cause a decline in demand for our products and services, including loans and deposits which may result in a significant decrease in business and would negatively impact our liquidity position, our growth strategy and our ability to make payments under our debt obligations as they become due. Our financial results could also be impacted due to an inability of our customers to meet their loan commitments because of their losses associated with impacts of the disease, and could also result in increased risk of delinquencies, defaults, foreclosures, declining collateral values and the ability of our borrowers to repay their loans resulting in losses to our Bank. Moreover, current and future governmental action may temporarily require the Company to conduct business related to foreclosures, repossessions, payments, deferrals and other customer-related transactions differently.
Although the Company has established a pandemic response plan and procedures, our workforce has been, is, and may continue to be impacted by COVID-19. We are taking precautions to protect the safety and well-being of our employees and customers, including temporary branch and office closures, but no assurance can be given that our actions will be adequate or appropriate, nor can we predict the level of disruption which will occur to our employees’ ability to provide customer support and service. The spread could also negatively impact availability of key personnel and employee productivity, as well as the business and operations of third-party service providers who perform critical services for us, which could adversely impact our ability to deliver products and services to our customers.

Federal and state governments have enacted laws intending to stimulate the economy. President Trump has signed into law three economic stimulus packages, including the $2.0 trillion Coronavirus Relief and Economic Security Act on March 26, 2020, which, among other things, initiated the Small Business Administration PPP. On April 16, 2020 the original $349.0 billion of funding under the PPP ran out, however on April 24, 2020 the Federal Government added an additional $310.0 billion. Our Bank participated as a lender in both the initial and second rounds of the PPP which was designed to help small businesses maintain their workforce during the COVID-19 pandemic. As of April 24, 2020, we have made approximately 2,300 PPP loans totaling over $600.0 million. The Company understands that these loans are fully guaranteed by the U.S. government and believes the majority of these loans will be forgiven. However, in the event of a loss resulting from a default on a PPP loan and a determination by the SBA that there was a deficiency in the manner in which the PPP loan was originated, funded or serviced by the Bank, which may or may not be related to an ambiguity in the laws, rules or guidance regarding operation of the PPP, the SBA may deny its liability under the guaranty, reduce the amount of the guaranty, or, if it has already been paid under the guaranty, seek recovery of any loss related to the deficiency from the Company. In addition, there can be no assurance that the borrowers will use the funds appropriately to qualify for forgiveness.
Since the opening of the PPP, several other larger banks have been subject to litigation regarding the process and procedures that such banks used in processing applications for the PPP. The Company and the Bank may be exposed to the risk of similar litigation, from both customers and non-customers that approached the Bank regarding PPP loans, regarding its processes and procedures used in processing applications for the PPP. If any such litigation is filed against the Bank and is not resolved in a manner favorable to the Bank, it may result in significant financial liability or adversely affect the Company's reputation. In addition, litigation can be costly, regardless of outcome. Any financial liability, litigation costs or reputational damage caused by PPP related litigation could have a material adverse impact on our business, financial condition and results of operations.
