PART I
ITEM 1. BUSINESS.
THE COMPANY
Great Southern Bancorp, Inc.
Great Southern Bancorp, Inc. ("Bancorp" or "Company") is a bank holding company, a financial holding company and the parent of Great Southern Bank ("Great Southern" or the "Bank"). Bancorp was incorporated under the laws of the State of Delaware in July 1989 as a unitary savings and loan holding company. The Company became a one-bank holding company on June 30, 1998, upon the conversion of Great Southern to a Missouri-chartered trust company. In 2004, Bancorp was re-incorporated under the laws of the State of Maryland.
As a Maryland corporation, the Company is authorized to engage in any activity that is permitted by the Maryland General Corporation Law and not prohibited by law or regulatory policy. The Company currently conducts its business as a financial holding company. Through the financial holding company structure, it is possible to expand the size and scope of the financial services offered by the Company beyond those offered by the Bank. The financial holding company structure provides the Company with greater flexibility than the Bank has to diversify its business activities, through existing or newly formed subsidiaries, or through acquisitions of or mergers with other financial institutions as well as other companies. At December 31, 2017, Bancorp's consolidated assets were $4.41 billion, consolidated net loans were $3.73 billion, consolidated deposits were $3.60 billion and consolidated total stockholders' equity was $471.7 million. For details about the Company's assets, revenues and profits for each of the last five fiscal years, see Item 6. "Selected Financial Data." The assets of the Company consist primarily of the stock of Great Southern and cash.
Through the Bank and subsidiaries of the Bank, the Company has historically offered insurance, travel, investment and related services, which are discussed further below. The travel and investment services divisions were sold on November 30, 2012. The activities of the Company are funded by retained earnings and through dividends from Great Southern. Activities of the Company may also be funded through borrowings from third parties, sales of additional securities or through income generated by other activities of the Company.
The executive offices of the Company are located at 1451 East Battlefield, Springfield, Missouri 65804, and its telephone number at that address is (417) 887-4400.
Great Southern Bank
Great Southern was formed as a Missouri-chartered mutual savings and loan association in 1923, and, in 1989, converted to a Missouri-chartered stock savings and loan association. In 1994, Great Southern changed to a federal savings bank charter and then, on June 30, 1998, changed to a Missouri-chartered trust company (the equivalent of a commercial bank charter). Headquartered in Springfield, Missouri, Great Southern offers a broad range of banking services through its 104 banking centers located in southern and central Missouri; the Kansas City, Missouri area; the St. Louis, Missouri area; eastern Kansas; northwestern Arkansas; eastern Nebraska; the Minneapolis, Minnesota area and eastern, western and central Iowa. At December 31, 2017, the Bank had total assets of $4.40 billion, net loans of $3.73 billion, deposits of $3.64 billion and equity capital of $533.2 million, or 12.1% of total assets. Its deposits are insured by the Deposit Insurance Fund ("DIF") to the maximum levels permitted by the FDIC.
The size and complexity of the Bank's operations increased substantially in 2009 with the completion of two Federal Deposit Insurance Corporation ("FDIC")-assisted transactions, and again in 2011, 2012 and 2014 with the completion of another FDIC-assisted transaction in each of those years. In 2009, the Bank entered into two separate purchase and assumption agreements (including loss sharing) with the FDIC to assume all of the deposits (excluding brokered deposits) and certain liabilities and acquire certain assets of TeamBank, N.A. and Vantus Bank. In these two transactions we acquired assets with a fair value of approximately $499.9 million (approximately 18.8% of the Company's total consolidated assets at acquisition) and $294.2 million (approximately 8.8% of the Company's total consolidated assets at acquisition), respectively, and assumed liabilities with a fair value of $610.2 million (approximately 24.9% of the Company's total consolidated assets at acquisition) and $440.0 million (approximately 13.2% of the Company's total consolidated assets at acquisition), respectively. They also resulted in gains of $43.9 million and $45.9 million, respectively, which were included in Noninterest Income in the Company's Consolidated Statement of Income for the year ended December 31, 2009. Prior to these acquisitions, the Company operated banking centers in Missouri with loan production offices in Arkansas and Kansas. These acquisitions added 31 banking centers and expanded our footprint to cover five states – Iowa, Kansas, Missouri, Arkansas and Nebraska. In 2011, the Bank entered into a purchase and assumption agreement (including loss sharing) with the FDIC to assume all of the deposits and certain liabilities and acquire certain assets of Sun Security Bank, which added locations in southern Missouri and St. Louis. In this transaction we acquired assets with a fair value of approximately $248.9 million (approximately 7.3% of the Company's total consolidated assets at acquisition) and assumed liabilities with a fair value of $345.8
3

million (approximately 10.1% of the Company's total consolidated assets at acquisition). It also resulted in a gain of $16.5 million which was included in Noninterest Income in the Company's Consolidated Statement of Income for the year ended December 31, 2011. In 2012, the Bank entered into a purchase and assumption agreement (including loss sharing) with the FDIC to assume all of the deposits and certain liabilities and acquire certain assets of Inter Savings Bank, FSB ("InterBank"), which added four locations in the greater Minneapolis, Minnesota area and represented a new market for the Company. In this transaction we acquired assets with a fair value of approximately $364.2 million (approximately 9.4% of the Company's total consolidated assets at acquisition) and assumed liabilities with a fair value of approximately $458.7 million (approximately 11.9% of the Company's total consolidated assets at acquisition). It also resulted in a gain of $31.3 million which was included in Noninterest Income in the Company's Consolidated Statement of Income for the year ended December 31, 2012.
In 2014, the Bank entered into a purchase and assumption agreement (without loss sharing) with the FDIC to assume all of the deposits and certain liabilities and acquire certain assets of Valley Bank ("Valley"), which added five locations in the Quad Cities area of eastern Iowa and six locations in central Iowa, primarily in the Des Moines market area. These represented new markets for the Company in eastern Iowa and enhanced our market presence in central Iowa. In this transaction we acquired assets with a fair value of approximately $378.7 million (approximately 10.0% of the Company's total consolidated assets at acquisition) and assumed liabilities with a fair value of approximately $367.9 million (approximately 9.8% of the Company's total consolidated assets at acquisition). It also resulted in a gain of $10.8 million which was included in Noninterest Income in the Company's Consolidated Statement of Income for the year ended December 31, 2014.
Also in 2014, the Bank entered into a purchase and assumption agreement to acquire certain assets and depository accounts from Neosho, Mo.-based Boulevard Bank ("Boulevard"), which added one location in the Neosho, Mo. market, where the Company already operated. In this transaction, which was completed in 2014, we acquired assets (primarily cash and cash equivalents) with a fair value of approximately $92.5 million (approximately 2.6% of the Company's total consolidated assets at acquisition) and assumed liabilities (all deposits and related accrued interest) with a fair value of approximately $93.3 million (approximately 2.6% of the Company's total consolidated assets at acquisition). This acquisition resulted in recognition of $790,000 of goodwill.
The Company also opened commercial loan production offices in Dallas, Texas and Tulsa, Oklahoma during 2014. The primary products offered in these offices are commercial real estate, commercial business and commercial construction loans.
In 2015, the Company announced plans to consolidate operations of 16 banking centers into other nearby Great Southern banking center locations. As part of an ongoing performance review of its entire banking center network, Great Southern evaluated each location for a number of criteria, including access and availability of services to affected customers, the proximity of other Great Southern banking centers, profitability and transaction volumes, and market dynamics. Subsequent to this announcement, the Bank entered into separate definitive agreements to sell two of the 16 banking centers, including all of the associated deposits (totaling approximately $20 million), to separate bank purchasers. One of those sale transactions was completed on February 19, 2016 and the other was completed on March 18, 2016. The closing of the remaining 14 facilities, which resulted in the transfer of approximately $127 million in deposits and banking center operations to other Great Southern locations, occurred at the close of business on January 8, 2016.
Also in 2015, the Company announced that it entered into a purchase and assumption agreement to acquire 12 branches, including related loans and to assume related deposits in the St. Louis, Mo., area from Cincinnati-based Fifth Third Bank. The acquisition was completed at the close of business on January 29, 2016. The deposits assumed totaled approximately $228 million and had a weighted average rate of approximately 0.28%. The loans acquired totaled approximately $159 million and had a weighted average yield of approximately 3.92%.
The loss sharing agreements related to the FDIC-assisted transactions in 2009, 2011 and 2012 added to the complexity of our operations by creating the need for new employees and processes to ensure compliance with the loss sharing agreements and the collection of problem assets acquired. See Note 4 included in Item 8. "Financial Statements and Supplementary Information" for a more detailed discussion of these FDIC-assisted transactions and the loss sharing agreements. The loss sharing agreements related to the 2009 and 2011 FDIC-assisted transactions were terminated during 2016. The loss sharing agreements related to the 2012 FDIC-assisted transaction were terminated during 2017. See "Loss Share Agreements" below for additional information regarding the termination of these agreements.
The Company opened a commercial loan production office in Chicago, Illinois during 2017. The primary products offered in this office are commercial real estate, commercial business and commercial construction loans.
Great Southern is principally engaged in the business of originating commercial real estate loans, construction loans, other commercial loans, residential real estate loans and consumer loans and funding these loans by attracting deposits from the general public, obtaining brokered deposits and through borrowings from the Federal Home Loan Bank of Des Moines (the "FHLBank") and others.

For many years, Great Southern has followed a strategy of emphasizing loan origination through residential, commercial and consumer lending activities in its market areas. The goal of this strategy is to be one of the leading providers of financial services in Great Southern's market areas, while simultaneously diversifying assets and reducing interest rate risk by originating and holding adjustable-rate loans and fixed-rate loans, primarily with terms of five years or less, in its portfolio and by selling longer-term fixed-rate single-family mortgage loans in the secondary market. The Bank continues to place emphasize real estate lending while also expanding and increasing its originations of commercial business and consumer loans.
The corporate office of the Bank is located at 1451 East Battlefield, Springfield, Missouri 65804 and its telephone number at that address is (417) 887-4400.

The Company regularly evaluates its banking center network and lines of business to ensure that it is serving customers in the best way possible. The banking center network constantly evolves with changes in customer needs and preferences, emerging technology and local market developments. In response to these changes, the Company opens banking centers and invests resources where customer demand leads, and from time to time, consolidates banking centers when market conditions dictate.
Great Southern's largest concentration of deposits and loans are in the Springfield, Mo., and St. Louis, Mo., market areas. In the last several years, the Company's deposit and loan portfolios have become more diversified because of its participation in five FDIC-assisted acquisitions and organic growth. The FDIC-assisted acquisitions significantly expanded the Company's geographic footprint, which prior to 2009 was primarily in southwest and central Missouri, by adding operations in Iowa, Kansas, Minnesota and Nebraska. Besides the Springfield and St. Louis market areas, the Company has deposit and loan concentrations in the following market areas: Kansas City, Mo.; Branson, Mo.; Sioux City, Iowa; Des Moines, Iowa; Northwest Arkansas; Omaha, Neb.; Minneapolis, Minn.; and Eastern Iowa in the area known as the "Quad Cities." Deposits and loans are also generated in banking centers in rural markets in Missouri, Iowa, Kansas and Nebraska.
At December 31, 2017, the Company's total deposits were $3.6 billion. At that date, the Company had deposits in Missouri of $2.5 billion, including the two largest deposit concentrations in Springfield and St. Louis, with $1.3 billion and $515 million, respectively. The Company also had deposits of $568 million in Iowa, $263 million in Minnesota, $165 million in Kansas (excluding the Kansas City metropolitan area), $59 million in Nebraska and $20 million in Arkansas.
At December 31, 2017, the Company's total loan portfolio balance, excluding acquired loans, was $3.6 billion. Geographically, the loan portfolio consists of loans collateralized by property (real estate and other assets) located in the following regions (including aggregate loan balance and percentage of total loans): St. Louis ($674 million, 19%); Springfield, Mo. ($386 million, 11%); Texas ($370 million, 10%); Oklahoma ($257 million, 7%); Iowa/Nebraska/South Dakota ($249 million, 7%); Kansas City ($249 million, 7%); Minnesota ($164 million, 5%); Northwest Arkansas ($114 million, 3%); Branson ($78 million, 2%); Chicago ($61 million, 2%); other Missouri regions ($344 million, 10%); other Kansas regions ($89 million, 2%); other Arkansas regions ($79 million, 2%); and other states and regions ($455 million, 13%).
The Company's net book balance of its portfolio of FDIC-acquired loans which were previously covered by loss sharing agreements was $172 million as of December 31, 2017. In 2016 and 2017, Great Southern Bank executed agreements with the FDIC to terminate the loss sharing agreements for Team Bank, Vantus Bank, Sun Security Bank and InterSavings Bank, which were a part of FDIC-assisted transactions completed in 2009, 2011 and 2012. Geographically, the total loan portfolio with terminated loss share agreements at December 31, 2017, consists of loans collateralized by property (real estate and other assets) located in the following regions (including aggregate gross loan balance and percentage of total loans): Minneapolis ($110 million, 64%); Iowa/Nebraska/South Dakota ($18 million, 10%); St. Louis ($12 million, 7%); Southwest Missouri ($9 million, 5%); Kansas City ($8 million, 5%); other Missouri ($6 million, 3%); Other Kansas ($3 million, 2%); and other regions ($6 million, 4%).
The Company's net book balance of its portfolio of loans which were acquired in the Valley Bank FDIC-assisted transaction was $60 million as of December 31, 2017. These loans were initially recorded at their fair value on the acquisition date of June 20, 2014. No loss sharing agreement was included in this transaction. Geographically, as of December 31, 2017, this portfolio consisted of loans collateralized by property (real estate and other assets) located in the following regions (including aggregate gross loan balance and percentage of total loans): Iowa/Nebraska/South Dakota ($38 million, 64%); Florida ($11 million, 18%); and other regions ($ 11 million, 18%).
Lending Activities
General
From its beginnings in 1923 through the early 1980s, Great Southern primarily made long-term, fixed-rate residential real estate loans that it retained in its loan portfolio. Beginning in the early 1980s, Great Southern increased its efforts to originate short-term and adjustable-rate loans. Beginning in the mid-1980s, Great Southern increased its efforts to originate commercial real estate and other residential loans, primarily with adjustable rates or shorter-term fixed rates. In addition, some competitor banking organizations merged with larger institutions and changed their business practices or moved operations away from the Springfield, Mo. area, and others consolidated operations from the Springfield, Mo. area to larger cities. This provided Great Southern expanded opportunities in residential and commercial real estate lending as well as in the origination of commercial business and consumer loans, primarily in indirect automobile lending.
In addition to origination of these loans, the Bank has expanded and enlarged its relationships with smaller banks and other peer banks to purchase participations (at par, generally with no servicing costs) in loans these other banks originate but are unable to retain in their portfolios due to capital or borrower relationship size limitations. The Bank uses the same underwriting guidelines in evaluating
6

these participations as it does in its direct loan originations. At December 31, 2017, the balance of participation loans purchased and held in the portfolio, excluding those covered by loss sharing agreements, was $201.5 million, or 5.7% of the total loan portfolio. All of these participation loans were performing at December 31, 2017.
One of the principal historical lending activities of Great Southern is the origination of fixed and adjustable-rate conventional residential real estate loans to enable borrowers to purchase or refinance owner-occupied homes. Great Southern originates a variety of conventional, residential real estate mortgage loans, principally in compliance with Freddie Mac and Fannie Mae standards for resale in the secondary market. Great Southern promptly sells most of the fixed-rate residential mortgage loans that it originates. To date, Great Southern has not experienced difficulties selling these loans in the secondary market and has had minimal requests for repurchase. Depending on market conditions, the ongoing servicing of these loans is at times retained by Great Southern, but generally servicing is released to the purchaser of the loan. Great Southern retains in its portfolio substantially all of the adjustable-rate mortgage loans that it originates.
Another principal lending activity of Great Southern is the origination of commercial real estate, multi-family and commercial construction loans. Since the early 1990s, commercial real estate, multi-family and commercial construction loans have represented the largest percentage of the loan portfolio. At December 31, 2017, commercial real estate, multi-family and commercial construction loans, excluding loans acquired in FDIC-assisted transactions, accounted for approximately 28%, 16% and 20%, respectively, of the total portfolio. Of the portfolio of acquired loans, commercial real estate loans (net of fair value discounts) accounted for approximately 1% of the total portfolio at December 31, 2017.
In addition, Great Southern in recent years has increased its emphasis on the origination of other commercial loans, home equity loans and consumer loans, and also issues of letters of credit. Letters of credit are contingent obligations and are not included in the Bank's loan portfolio. See "-- Other Commercial Lending," "- Classified Assets," and "Loan Delinquencies and Defaults" below.
The percentage of collateral value Great Southern will loan on real estate and other property varies based on factors including, but not limited to, the type of property and its location and the borrower's credit history. As a general rule, Great Southern will loan up to 95% of the appraised value on one-to four-family residential properties. Typically, private mortgage insurance is required for loan amounts above the 80% level. At December 31, 2017 and 2016, loans secured by second liens on residential properties were $126.7 million, or 3.3%, and $138.1 million, or 3.9%, respectively, of our total loan portfolio. For commercial real estate and other residential real property loans, Great Southern may loan up to 85% of the appraised value. The origination of loans secured by other property is considered and determined on an individual basis by management with the assistance of any industry guides and other information which may be available. Collateral values are reappraised or reassessed as loans are renewed or when significant events indicating potential impairment occur. On a quarterly basis, management reviews impaired loans to determine whether updated appraisals or reassessments are necessary based on loan performance, collateral type and guarantor support. While not specifically required by our policy, we seek to obtain cross-collateralization of loans to a borrower when it is available and it is most frequently done on commercial real estate loans.
Loan applications are approved at various levels of authority, depending on the type, amount and loan-to-value ratio of the loan. Loan commitments of more than $750,000 (or loans exceeding the Freddie Mac loan limit in the case of fixed-rate, one- to four-family residential loans for resale) must be approved by Great Southern's loan committee. The loan committee is comprised of the Chief Executive Officer of the Bank, the Chief Credit Officer of the Bank (chairman of the committee), and other senior officers of the Bank involved in lending activities. All loans, regardless of size or type, are required to conform to certain minimum underwriting standards to assure portfolio quality. These standards and procedures include, but are not limited to, an analysis of the borrower's financial condition, collateral, repayment ability, verification of liquid assets and credit history as required by loan type. It has been, and continues to be, our practice to verify information from potential borrowers regarding assets, income or payment ability and credit ratings as applicable and as required by the authority approving the loan. Underwriting standards also include loan-to-value ratios which vary depending on collateral type, debt service coverage ratios or debt payment to income ratios, where applicable, credit histories, use of guaranties and other recommended terms relating to equity requirements, amortization, and maturity. Generally, deviations from approved underwriting standards can only be allowed when doing so is not in violation of regulations or statutes and when appropriate lending authority is obtained. The loan committee reviews all new loan originations in excess of lender approval authorities. For secured loans originated and held, most lenders have approval authorities of $250,000 or below while fifteen senior lenders have approval authority of varying amounts up to $1 million. Lender approval authorities are also subject to loans-to-one borrower limits of $500,000 or below for most lenders and of varying amounts up to $3 million for fourteen senior lenders. These standards, as well as our collateral requirements, have not significantly changed in recent years.
In general, state banking laws restrict loans to a single borrower and related entities to no more than 25% of a bank's unimpaired capital and unimpaired surplus, plus an additional 10% if the loan is collateralized by certain readily marketable collateral. (Real estate is not included in the definition of "readily marketable collateral.") As computed on the basis of the Bank's unimpaired capital and surplus at December 31, 2017, this limit was approximately $139.7 million. See "Government Supervision and Regulation." At December 31, 2017, the Bank was in compliance with the loans-to-one borrower limit. At December 31, 2017, the Bank's largest
7

relationship for purposes of this limit, which consists of eight loans, totaled $51.7 million. This amount represents the total commitment for this relationship at December 31, 2017; the outstanding balance at that date was $37.6 million. The collateral for the loans consists of multiple healthcare facilities, apartment complexes and a retail development. Some of the projects are currently under construction, so all funds have not been disbursed on these loan. In addition, we obtained personal guarantees from the principal owner of the borrowing entities for each of these loans. All loans included in this relationship were current at December 31, 2017. In addition at December 31, 2017, we had four other loan relationships that each exceeded $40 million. All loans included in these relationships were current at December 31, 2017. Our policy does not set a loans-to-one borrower limit that is below the legal limits described; however, we do recognize the need to limit credit risk to any one borrower or group of related borrowers upon consideration of various risk factors. Extensions of credit to borrowers whose past due loans were charged-off or whose loans are classified as substandard require special lending approval.
Great Southern is permitted under applicable regulations to originate or purchase loans and loan participations secured by real estate located in any part of the United States. In addition to the market areas where the Company has offices, the Bank has made or purchased loans, secured primarily by commercial real estate, in other states, primarily Michigan, Indiana, Florida, Georgia and Arizona. At December 31, 2017, loans in these states comprised less than 2% each, respectively, of the total loan portfolio.
Loan Portfolio Composition
The following tables set forth information concerning the composition of the Bank's loan portfolio in dollar amounts and in percentages (before deductions for loans in process, deferred fees and discounts and allowance for loan losses) as of the dates indicated. The tables are based on information prepared in accordance with generally accepted accounting principles and are qualified by reference to the Company's Consolidated Financial Statements and the notes thereto contained in Item 8 of this report.
The loans acquired in the four FDIC-assisted transactions completed in 2009 through 2012 were previously covered by loss sharing agreements between the FDIC and the Bank which afforded the Bank at least 80% protection from potential principal losses. Because of these loss sharing agreements, the composition of the loans acquired from the former TeamBank, Vantus Bank, Sun Security Bank and InterBank is shown below in tables separate from the legacy Great Southern portfolio. In addition, the composition of the loans acquired in 2014 from the former Valley Bank, which are not currently, and were not previously, covered by a loss sharing agreement, is shown below in tables separate from the legacy Great Southern portfolio. All of these acquired loan portfolios were initially recorded at their fair values at the acquisition date and are recorded by the Company at their discounted value. The following tables reflect the loan balances excluding discounts.

Through December 31, 2017, gross loan balances (due from the borrower) related to TeamBank were reduced approximately $422.5 million since the transaction date because of $289.7 million of principal repayments, $61.7 million of transfers to foreclosed assets and $71.1 million of charge-downs to customer loan balances. Gross loan balances (due from the borrower) related to Vantus Bank were reduced approximately $312.6 million since the transaction date because of $266.9 million of principal repayments, $16.7 million of transfers to foreclosed assets and $29.0 million of charge-downs to customer loan balances. Gross loan balances (due from the borrower) related to Sun Security Bank were reduced approximately $207.7 million since the transaction date because of $148.4 million of principal repayments, $28.4 million of transfers to foreclosed assets and $30.9 million of charge-offs to customer loan balances. Gross loan balances (due from the borrower) related to InterBank were reduced approximately $280.9 million since the transaction date because of $239.4 million of principal repayments, $19.1 million of transfers to foreclosed assets and $22.4 million of charge-offs to customer loan balances. Gross loan balances (due from the borrower) related to Valley Bank were reduced approximately $133.2 million since the transaction date because of $121.4 million of principal repayments, $4.0 million of transfers to foreclosed assets and $7.8 million of charge-offs to customer loan balances. Based upon the collectability analyses performed at the time of the acquisitions, we expected certain levels of foreclosures and charge-offs, and actual results through December 31, 2017, related to the FDIC-assisted acquired portfolios, have been better than our expectations. As a result, cash flows expected to be received from the acquired loan pools have increased, resulting in adjustments that were made to the related accretable yield which are discussed in Note 4 of the accompanying audited financial statements, included in Item 8 of this Report.

As of December 31, 2017, loans due after December 31, 2018 with fixed interest rates totaled $30.2 million and loans due after December 31, 2018 with adjustable rates totaled $9.9 million.
At December 31, 2017, $126.7 million, or 3.3%, of total loans were secured by junior lien mortgages and $4.5 million, or 1.4% of residential real estate loans, were interest only residential real estate loans. At December 31, 2016, $138.1 million, or 3.6%, of total loans were secured by junior lien mortgages and $5.9 million, or 1.6% of residential real estate loans, were interest only residential real estate loans. While high loan-to-value ratio mortgage loans are occasionally originated and held, they are typically either considered low risk based on analyses performed or are required to have private mortgage insurance. The Company does not originate or hold option ARM loans or significant amounts of loans with initial teaser rates or subprime loans in its residential real estate portfolio.
To monitor and control risks related to concentrations of credit in the composition of the loan portfolio, management reviews the loan portfolio by loan types, industries and market areas on a monthly basis for credit quality and known and anticipated market conditions. Changes in loan portfolio composition may be made by management based on the performance of each area of business, known and anticipated market conditions, credit demands, the deposit structure of the Bank and the expertise and/or depth of the lending staff. Loan portfolio industry and market areas are monitored regularly for credit quality and trends. Reports detailed by industry and geography are provided to the Board of Directors on a monthly and quarterly basis.
In response to the economic recession that began in 2008, the composition of the Bank's loan portfolio has changed over the past several years; speculative construction and land development loan types have been limited to reduce the risk, commercial real estate loan types have been stabilized and diversified and emphasis has been placed on increasing our multi-family, commercial business and consumer loan portfolios.
Environmental Issues
Loans secured by real property, whether commercial, residential or other, may have a material, negative effect on the financial position and results of operations of the lender if the collateral is environmentally contaminated. The result can be, but is not necessarily limited to, liability for the cost of cleaning up the contamination imposed on the lender by certain federal and state laws, a reduction in the borrower's ability to pay because of the liability imposed upon it for any clean-up costs, a reduction in the value of the collateral because of the presence of contamination or a subordination of security interests in the collateral to a super priority lien securing the cleanup costs by certain state laws.

Management is aware of the risk that the Bank may be negatively affected by environmentally contaminated collateral and attempts to control this risk through commercially reasonable methods, consistent with guidelines arising from applicable government or regulatory rules and regulations, and to a more limited extent, publications of the lending industry. Management currently is unaware (without, in many circumstances, specific inquiry or investigation of existing collateral, some of which was accepted as collateral before risk controlling measures were implemented) of any environmental contamination of real property securing loans in the Bank's portfolio that would subject the Bank to any material risk. No assurance can be given, however, that the Bank will not be adversely affected by environmental contamination.
Residential Real Estate Lending
At December 31, 2017 and 2016, loans secured by residential real estate, excluding that which is under construction and excluding all FDIC-assisted acquired loans, totaled $1.1 billion and $1.0 billion, respectively, and represented approximately 23.3% and 23.1%, respectively, of the Bank's total loan portfolio. At December 31, 2017 and 2016, FDIC-assisted acquired loans (net of fair value discounts) secured by residential real estate totaled $134 million and $184 million, respectively, and represented approximately 2.9% and 4.2%, respectively, of the Bank's total loan portfolio. The Bank's legacy one- to four-family residential real estate loan portfolio increased during 2017, primarily due to organic loan growth in multi-family loans. One-to four-family residential real estate loans increased significantly in 2014 with the FDIC-assisted acquisition of Valley Bank. Since 2010, other residential real estate (multi-family) loan balances continued to increase as the Bank has emphasized this type of loan. The Bank's legacy multi-family residential real estate loan portfolio grew by about 12% and 58% in 2017 and 2016, respectively. In 2013, the Bank completed a non-FDIC-assisted acquisition of a portfolio of multi-family loans totaling $86 million.
The Bank currently is originating one- to four-family adjustable-rate residential mortgage loans primarily with one-year adjustment periods. Rate adjustments on loans originated prior to July 2001 are based upon changes in prevailing rates for one-year U.S. Treasury securities. Rate adjustments on loans originated since July 2001 are based upon changes in the average of interbank offered rates for twelve month U.S. Dollar-denominated deposits in the London Market (LIBOR) or changes in prevailing rates for one-year U.S. Treasury securities. Rate adjustments are generally limited to 2% maximum annually as well as a maximum aggregate adjustment over the life of the loan. Accordingly, the interest rates on these loans typically may not be as rate sensitive as is the Bank's cost of funds. Generally, the Bank's adjustable-rate mortgage loans are not convertible into fixed-rate loans, do not permit negative amortization of principal and carry no prepayment penalty. The Bank also currently is originating other residential (multi-family) mortgage loans with interest rates that are generally either adjustable with changes to the prime rate of interest or fixed for short periods of time (three to seven years).
The Bank's portfolio of adjustable-rate mortgage loans also includes a number of loans with different adjustment periods, without limitations on periodic rate increases and rate increases over the life of the loans, or which are tied to other short-term market indices. These loans were originated prior to the industry standardization of adjustable-rate loans. Since the adjustable-rate mortgage loans currently held in the Bank's portfolio have not been subject to an interest rate environment which causes them to adjust to the maximum, these loans entail unquantifiable risks resulting from potential increased payment obligations on the borrower as a result of upward repricing. The indices used by Great Southern for these types of loans have increased, but not significantly, in the past three years. Compared to fixed-rate mortgage loans, these loans are subject to increased risk of delinquency or default if a higher, fully-indexed rate of interest subsequently comes into effect in replacement of a lower rate currently in effect. From 2008 through 2012, as a result of the significant recession in the economy, including residential real estate, the Bank experienced a significant increase in delinquencies in adjustable-rate mortgage loans. In 2013 through 2017, these delinquencies have trended lower.
In underwriting one- to four-family residential real estate loans, Great Southern evaluates the borrower's ability to make monthly payments and the value of the property securing the loan. It is the policy of Great Southern that generally all one- to four-family residential loans in excess of 80% of the appraised value of the property be insured by a private mortgage insurance company approved by Great Southern for the amount of the loan in excess of 80% of the appraised value. In addition, Great Southern requires borrowers to obtain title and fire and casualty insurance in an amount not less than the amount of the loan. Real estate loans originated by the Bank generally contain a "due on sale" clause allowing the Bank to declare the unpaid principal balance due and payable upon the sale of the property securing the loan. The Bank may enforce these due on sale clauses to the extent permitted by law.
Commercial Real Estate and Construction Lending
Commercial real estate lending has been a significant part of Great Southern's business activities since the mid-1980s. Great Southern does commercial real estate lending in order to increase the potential yield on, and the proportion of interest rate sensitive loans in, its portfolio. At December 31, 2008, commercial real estate loans and commercial construction loans each made up about one fourth of the total loan portfolio. The economic recession that began in 2008 resulted in reduced activity in the market caused by the downturn in the economy and reduced real estate values. In response, Great Southern began limiting residential and commercial land development lending to reduce the risk in the portfolio and began originating an increased amount of commercial real estate loans. Since December 31, 2008, the commercial land development construction loan portfolio has decreased from 32% of the loan portfolio
25

to 13% of the loan portfolio at December 31, 2017, while, overall, commercial real estate loans have trended upward. The increase in commercial real estate loans in 2015, 2016 and 2017 reflects some economic improvement with increased investor activity in sales, purchases and refinancing of these types of properties. Both commercial real estate occupancy and rental rates show improvement in the Bank's market areas. Excluding FDIC-assisted acquired loans, over the last three years, commercial real estate loans made up approximately 27-28% of the total loan portfolio while commercial construction loans were 15-20%. Great Southern expects to continue to limit lending on land development loans in 2018 with increases in commercial construction and commercial real estate anticipated as long as the economy continues to be strong. See "Government Supervision and Regulation" below.
At December 31, 2017 and 2016, loans secured by commercial real estate, excluding that which is under construction and excluding all FDIC-assisted acquired loans, totaled $1.3 billion and $1.2 billion, respectively, or approximately 27.5% and 27.5%, respectively, of the Bank's total loan portfolio. At December 31, 2017 and 2016, FDIC-acquired loans (net of fair value discounts) secured by commercial real estate totaled $39 million and $54 million, respectively, and represented approximately 0.9% and 1.2%, respectively, of the Bank's total loan portfolio. In addition, at December 31, 2017 and 2016, construction loans, excluding all FDIC-acquired loans, secured by projects under construction and the land on which the projects are located aggregated $1.2 billion and $870 million, respectively, or 25.2% and 19.8%, respectively, of the Bank's total loan portfolio. At December 31, 2017 and 2016, FDIC-acquired construction loans (net of fair value discounts) totaled $5 million and $3 million, respectively, and represented approximately 0.1% and 0.1%, respectively, of the Bank's total loan portfolio. A majority of the Bank's commercial real estate loans have been originated with adjustable rates of interest, most of which are tied to the national prime rate, or fixed rates of interest with short-term maturities. A large majority of the Bank's commercial real estate loans (both fixed and adjustable) mature in five years or less. Substantially all of these loans were originated with loan commitments which did not exceed 80% of the appraised value of the properties securing the loans.
The Bank's construction loans generally have a term of eighteen months or less. The construction loan agreements for one- to four-family projects generally require principal reductions as individual condominium units or single-family houses are built and sold to a third party. This insures that the remaining loan balance, as a proportion of the value of the remaining security, does not increase, assuming that the value of the remaining security does not decrease. Loan proceeds are disbursed in increments as construction progresses. Generally, the amount of each disbursement is based on the construction cost estimate with inspections of the project performed in connection with each disbursement request. Normally, Great Southern's commercial real estate and other residential construction loans are made either as the initial stage of a combination loan (i.e., with a commitment from the Bank to provide permanent financing upon completion of the project) or with a commitment from a third party to provide permanent financing.
The Bank's commercial real estate and construction loan portfolios consist of loans with diverse collateral types. The following table sets forth loans that were secured by certain types of collateral at December 31, 2017, excluding FDIC-assisted acquired loans. These collateral types represent the five highest percentage concentrations of commercial real estate and construction loan types in the loan portfolio.

Collateral Type |  | Loan Balance |  |  | Percentage of Total Loan Portfolio |  |  | Non-Performing Loans at December 31, 2017 |
|  | (Dollars In Thousands) |
Retail (Varied Projects) |  | $ | 483,065 |  |  |  | 13.6 | % |  | $ | 146 |
Health Care Facilities |  | $ | 247,770 |  |  |  | 7.0 | % |  | $ | 0 |
Office Industry |  | $ | 239,713 |  |  |  | 6.7 | % |  | $ | 1,139 |
Warehouses |  | $ | 145,831 |  |  |  | 4.1 | % |  | $ | 0 |
Motels/Hotels |  | $ | 123,047 |  |  |  | 3.5 | % |  | $ | 202 |

Commercial real estate lending and construction lending generally affords the Bank an opportunity to receive interest at rates higher than those obtainable from residential mortgage lending and to receive higher origination and other loan fees. In addition, commercial real estate loans and construction loans are generally made with adjustable rates of interest or, if made on a fixed-rate basis, for relatively short terms. Nevertheless, commercial real estate lending entails significant additional risks as compared with residential mortgage lending. Commercial real estate loans typically involve large loan balances to single borrowers or groups of related borrowers. In addition, the payment experience on loans secured by commercial properties is typically dependent on the successful operation of the related real estate project and thus may be subject, to a greater extent, to adverse conditions in the real estate market or in the economy generally.
Construction loans involve additional risks attributable to the fact that loan funds are advanced upon the security of the project under construction, which is of uncertain value prior to the completion of construction. Moreover, because of the uncertainties inherent in estimating construction costs, delays arising from labor problems, material shortages, and other unpredictable contingencies, it is
26

relatively difficult to evaluate accurately the total loan funds required to complete a project, and the related loan-to-value ratios. See also the discussion under the headings "- Classified Assets" and "- Loan Delinquencies and Defaults" below.
The Company executes interest rate swaps with certain commercial banking customers to facilitate their respective risk management strategies. The Company began offering this service during 2011. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. As of December 31, 2017, the Company had 22 interest rate swaps totaling $92.7 million in notional amount with commercial customers, and 22 interest rate swaps with the same notional amount with third parties related to this program. As of December 31, 2016, the Company had 26 interest rate swaps totaling $110.7 million in notional amount with commercial customers, and 26 interest rate swaps with the same notional amount with third parties related to this program. As part of the Valley Bank FDIC-assisted acquisition, the Company acquired seven loans with related interest rate swaps. Valley's swap program differed from the Company's in that Valley did not have back to back swaps with the customer and a counterparty. Two of the seven acquired loans with interest rate swaps have paid off. The notional amount of the five remaining Valley swaps is $3.6 million at December 31, 2017. During the years ended December 31, 2017 and 2016, the Company recognized net gains of $28,000 and $66,000 respectively, in noninterest income related to changes in the fair value of these swaps.
Other Commercial Lending
At December 31, 2017 and 2016, Great Southern had $354 million and $348 million, respectively, in other commercial loans outstanding, excluding all FDIC-acquired loans, or 7.7% and 7.9%, respectively, of the Bank's total loan portfolio. At December 31, 2017 and 2016, FDIC-acquired other commercial loans (net of fair value discounts) totaled $5 million and $6 million, respectively, and represented approximately 0.1% and 0.1%, respectively, of the Bank's total loan portfolio. Great Southern's other commercial lending activities encompass loans with a variety of purposes and security, including loans to finance accounts receivable, inventory and equipment. Great Southern expects to continue to originate loans in this category subject to market conditions and applicable regulatory restrictions. See "Government Supervision and Regulation" below.
Unlike residential mortgage loans, which generally are made on the basis of the borrower's ability to make repayment from his or her employment and other income and which are secured by real property, the value of which tends to be more easily ascertainable, other commercial loans are of higher risk and typically are made on the basis of the borrower's ability to make repayment from the cash flow of the borrower's business. Commercial loans are generally secured by business assets, such as accounts receivable, equipment and inventory. As a result, the availability of funds for the repayment of other commercial loans may be substantially dependent on the success of the business itself. Further, the collateral securing the loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business.
The Bank's management recognizes the generally increased risks associated with other commercial lending. Great Southern's commercial lending policy emphasizes complete credit file documentation and analysis of the borrower's character, capacity to repay the loan, the adequacy of the borrower's capital and collateral as well as an evaluation of the industry conditions affecting the borrower. Review of the borrower's past, present and future cash flows is also an important aspect of Great Southern's credit analysis. In addition, the Bank generally obtains personal guarantees from the borrowers on these types of loans. Historically, the majority of Great Southern's commercial loans have been to borrowers in southwestern and central Missouri and the St. Louis, Mo. area. With the acquisitions in 2009, 2011, 2012 and 2014, geographic concentrations for commercial loans expanded to include the greater Kansas City, Mo. area, several areas in Iowa, and the Minneapolis-St. Paul, Minn. area. Great Southern has continued its commercial lending in all of these geographic areas.
As part of its commercial lending activities, Great Southern issues letters of credit and receives fees averaging approximately 1% of the amount of the letter of credit per year. At December 31, 2017, Great Southern had 90 letters of credit outstanding in the aggregate amount of $20.0 million. Approximately 16% of the aggregate amount of these letters of credit was secured, including one $885,000 letter of credit secured by real estate which was issued to enhance the issuance of housing revenue refunding bonds and was current.
Consumer Lending
Great Southern management views consumer lending as an important component of its business strategy. Specifically, consumer loans generally have short terms to maturity, thus reducing Great Southern's exposure to changes in interest rates, and carry higher rates of interest than do residential mortgage loans. In addition, Great Southern believes that the offering of consumer loan products helps to expand and create stronger ties to its existing customer base.
Great Southern offers a variety of secured consumer loans, including automobile loans, boat loans, home equity loans and loans secured by savings deposits. In addition, Great Southern also offers home improvement loans and unsecured consumer loans.
27

Consumer loans, excluding all FDIC-acquired loans, totaled $536 million and $673 million at December 31, 2017 and 2016, respectively, or 11.7% and 15.3%, respectively, of the Bank's total loan portfolio. At December 31, 2017 and 2016, FDIC-assisted acquired consumer loans (net of fair value discounts) totaled $26 million and $35 million, respectively, and represented approximately 0.6% and 0.8%, respectively, of the Bank's total loan portfolio.
The underwriting standards employed by the Bank for consumer loans include a determination of the applicant's payment history on other debts and an assessment of ability to meet existing obligations and payments on the proposed loan. Although creditworthiness of the applicant is of primary consideration, the underwriting process also includes a comparison of the value of the security, if any, in relation to the proposed loan amount.
Beginning in 1998, the Bank implemented indirect lending relationships, primarily with automobile dealerships. Through these dealer relationships, the dealer completes the application with the consumer and then submits it to the Bank for credit approval. While the Bank's initial and ongoing concentrated effort was on automobiles, the program has evolved for use with other tangible products where financing of the product is provided through the seller, including, to a lesser extent, boats and manufactured homes. At December 31, 2017 and 2016, the Bank had $422 million and $568 million, respectively, of auto, boat, modular home and recreational vehicle loans in its portfolio, including FDIC-acquired loans totaling $3 million and $5 million, respectively.
Indirect consumer loans decreased significantly in 2017, primarily due to tightened underwriting guidelines on automobile lending implemented by the Company in the latter part of 2016, and were $336 million and $468 million at December 31, 2017 and 2016, respectively. We expect to see further declines in the indirect automobile loan totals through 2018 as well. The total indirect consumer loans at December 31, 2017 was comprised of the following types of loans: $287 million of used auto loans, $32 million of manufactured home loans, $13 million of new auto loans, $3 million of new boat loans, and various other loans including loans for RVs, used boats, ATVs and motorcycles.
Consumer loans may entail greater risk than do residential mortgage loans, particularly in the case of consumer loans that are unsecured or secured by rapidly depreciable assets such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation. The remaining deficiency often does not warrant further substantial collection efforts against the borrower. In addition, consumer loan collections are dependent on the borrower's continuing financial strength, and thus are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. Furthermore, the application of various federal and state laws, including federal and state consumer bankruptcy and insolvency laws, may limit the amount which can be recovered on these loans. These loans may also give rise to claims and defenses by a consumer loan borrower against an assignee of these loans such as the Bank, and a borrower may be able to assert against the assignee claims and defenses which it has against the seller of the underlying collateral.
Originations, Purchases, Sales and Servicing of Loans
The Bank originates loans through internal loan production personnel located in the Bank's main and branch offices, as well as loan production offices. Walk-in customers and referrals from existing customers of the Company are also important sources of loan originations.
Great Southern may also purchase whole loans and participation interests in loans (generally without recourse, except in cases of breach of representation, warranty or covenant) from other banks, thrift institutions and life insurance companies (originators). The purchase transaction is governed by a participation agreement entered into by the originator and participant (Great Southern) containing guidelines as to ownership, control and servicing rights, among others. The originator may retain all rights with respect to enforcement, collection and administration of the loan. This may limit Great Southern's ability to control its credit risk when it purchases participations in these loans. For instance, the terms of participation agreements vary; however, generally Great Southern may not have direct access to the borrower, and the institution administering the loan may have some discretion in the administration of performing loans and the collection of non-performing loans.
Over the years, a number of banks, both locally and regionally, have sought to diversify the risk in their portfolios. In order to take advantage of this situation, Great Southern purchases participations in commercial real estate, commercial construction and other commercial loans. Great Southern subjects these loans to its normal underwriting standards used for originated loans and rejects any credits that do not meet those guidelines. The originating bank retains the servicing of these loans. Excluding all FDIC-acquired loans, the Bank purchased $133.0 million and $145.6 million of these loans in the fiscal years ended December 31, 2017 and 2016, respectively. Of the total $201.5 million of purchased participation loans outstanding at December 31, 2017, the largest aggregate amount outstanding purchased from one institution was $16.4 million. This total was comprised of two loans; one which was secured by a mixed-use office and a student housing complex, and the other which was secured by an apartment complex, all of which were located in the Kansas City metro area. These loans were performing at December 31, 2017. At December 31, 2017 and 2016, loans which were previously covered by loss sharing agreements with the FDIC but are no longer covered included purchased and
28

participation loans of $249,000 and $1.2 million, respectively. At December 31, 2017 and 2016, FDIC-acquired loans which were never covered by loss sharing agreements included purchased and participation loans of $11.2 million and $13.6 million, respectively. These amounts represent the undiscounted balance of these loans.
In 2013, the Bank purchased $86.1 million of multi-family residential loans, which were auctioned by an unrelated FDIC-insured financial institution. The Bank paid $87.9 million for the loans, which resulted in a 2.125% premium over the principal balances of the portfolio. This purchased loan portfolio totaled $32.3 million and $38.9 million at December 31, 2017 and 2016, respectively. There were no loans from this purchased loan portfolio included in non-performing loans at December 31, 2017.
In 2014, the Bank purchased $20.9 million of commercial real estate loans (primarily retail projects with single tenants), which were auctioned by an unrelated FDIC-insured financial institution. The Bank paid $21.3 million for the loans, which resulted in a 1.64% premium over the principal balances of the portfolio. This purchased loan portfolio totaled $14.0 million and $17.7 million at December 31, 2017 and 2016, respectively. There were no loans from this purchased loan portfolio included in non-performing loans at December 31, 2017.
From time to time, Great Southern also sells non-residential loan participations generally without recourse to private investors, such as other banks, thrift institutions and life insurance companies (participants). The sales transaction is governed by a participation agreement entered into by the originator (Great Southern) and participant containing guidelines as to ownership, control and servicing rights, among others. Great Southern retains servicing rights for these participations sold. These participations are sold with a provision for repurchase upon breach of representation, warranty or covenant.
Great Southern also sells whole residential real estate loans without recourse to Freddie Mac and Fannie Mae as well as to private investors, such as other banks, thrift institutions, mortgage companies and life insurance companies. Whole real estate loans are sold with a provision for repurchase upon breach of representation, warranty or covenant. These representations, warranties and covenants include those regarding the compliance of loan originations with all applicable legal requirements, mortgage title insurance policies when applicable, enforceable liens on collateral, collateral type, borrower credit worthiness, private mortgage insurance when required and compliance with all applicable federal regulations. A minimal number of repurchase requests have been received to date based on a breach of representations, warranties or covenants as outlined in the investor contracts. These loans are generally sold for cash in amounts equal to the unpaid principal amount of the loans adjusted for current market yields to the buyer. The sale amounts generally produce gains to the Bank and allow a margin for servicing income on loans when the servicing is retained by the Bank. However, residential real estate loans sold in recent years have primarily been with Great Southern releasing control of the servicing of the loans.
The Bank sold one- to four-family whole real estate loans and loan participations in aggregate amounts of $135.5 million, $153.0 million and $154.8 million during fiscal 2017, 2016, and 2015, respectively. The Bank typically sells long-term fixed rate mortgages. Sales of whole real estate loans and participations in real estate loans can be beneficial to the Bank since these sales generally generate income at the time of sale, produce future servicing income on loans where servicing is retained, provide funds for additional lending and other investments, and increase liquidity.
Gains, losses and transfer fees on sales of loans and loan participations are recognized at the time of the sale. When real estate loans and loan participations sold have an average contractual interest rate that differs from the agreed upon yield to the purchaser (less the agreed upon servicing fee), resulting gains or losses are recognized in an amount equal to the present value of the differential over the estimated remaining life of the loans. Any resulting discount or premium is accreted or amortized over the same estimated life using a method approximating the level yield interest method. When real estate loans and loan participations are sold with servicing released, as the Bank primarily does, an additional fee is received for the servicing rights. Net gains and transfer fees on sales of loans for fiscal 2017, 2016 and 2015 were $3.2 million, $3.9 million and $3.9 million, respectively. These gains were from the sale of fixed-rate residential loans.
The Bank serviced loans owned by others totaling approximately $254.0 million and $266.2 million at December 31, 2017 and 2016, respectively. Of the total loans serviced at December 31, 2017, $164.8 million related to commercial real estate, commercial business and construction loans, portions of which were sold to other parties. The remaining $89.2 million of loans serviced for others related to one- to four-family real estate loans which the Bank had originated and sold, but retained the obligation to service, or had acquired the servicing through various FDIC-assisted transactions. The servicing of these loans generated fees (net of amortization of the servicing rights) to the Bank for the years ended December 31, 2017, 2016 and 2015, of $206,000, $220,000 and $241,000, respectively.
In addition to interest earned on loans and loan origination fees, the Bank receives fees for loan commitments, letters of credit, prepayments, modifications, late payments, transfers of loans due to changes of property ownership and other miscellaneous services. The fees vary from time to time, generally depending on the supply of funds and other competitive conditions in the market. Fees from prepayments, commitments, letters of credit and late payments totaled $2.4 million, $2.0 million and $2.3 million for the years ended December 31, 2017, 2016 and 2015, respectively. Loan origination fees, net of related costs, are accounted for in accordance with
29

FASB ASC 310-20, Receivables – Nonrefundable Fees and Other Costs. Loan fees and certain direct loan origination costs are deferred, and the net fee or cost is recognized in interest income using the level-yield method over the contractual life of the loan. For further discussion of this matter, see Note 1 of the accompanying audited financial statements, included in Item 8 of this Report.
Loan Delinquencies and Defaults
When a borrower fails to make a required payment on a loan, the Bank attempts to cause the delinquency to be cured by contacting the borrower. In the case of loans secured by residential real estate, a late notice is sent 15 days after the due date. If the delinquency is not cured by the 30th day, a delinquent notice is sent to the borrower.
Additional written contacts are made with the borrower 45 and 60 days after the due date. If the delinquency continues for a period of 65 days, the Bank usually institutes appropriate action to foreclose on the collateral. The actual time it takes to foreclose on the collateral varies depending on the particular circumstances and the applicable governing law. If foreclosed upon, the property is sold at public auction and may be purchased by the Bank. Delinquent consumer loans are handled in a generally similar manner, except that initial contacts are made when the payment is five days past due and appropriate action may be taken to collect any loan payment that is delinquent for more than 15 days. The Bank's procedures for repossession and sale of consumer collateral are subject to various requirements under the applicable consumer protection laws as well as other applicable laws and the determination by the Bank that it would be beneficial from a cost basis.
Delinquent commercial business loans and loans secured by commercial real estate are initially handled by the loan officer in charge of the loan, who is responsible for contacting the borrower. Senior management also works with the commercial loan officers to see that necessary steps are taken to collect delinquent loans. In addition, the Bank has a Problem Loan Committee which meets at least quarterly and reviews all classified assets, as well as other loans which management feels may present possible collection problems. If an acceptable workout of a delinquent commercial loan cannot be agreed upon, the Bank may initiate foreclosure proceedings on any collateral securing the loan. However, in all cases, whether a commercial or other loan, the prevailing circumstances may be such that management may determine it is in the best interest of the Bank not to foreclose on the collateral.

Classified Assets
Federal regulations provide for the classification of loans and other assets such as debt and equity securities considered to be of lesser quality as "substandard," "doubtful" or "loss" assets. The regulations require insured institutions to classify their own assets and to establish prudent specific allocations for losses from assets classified "substandard" or "doubtful." "Substandard" assets include those characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Assets classified as "doubtful," have all the weaknesses inherent in those classified as "substandard" with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. For the portion of assets classified as "loss," an institution is required to either establish specific allowances of 100% of the amount classified or charge such amount off its books. Assets that do not currently expose the insured institution to sufficient risk to warrant classification in one of the aforementioned categories but possess a potential weakness (referred to as "special mention" assets), are required to be listed on the Bank's watch list and monitored for further deterioration. In addition, a bank's regulators may require the establishment of a general allowance for losses based on the general quality of the asset portfolio of the bank. Following are the total classified assets at December 31, 2017 and 2016, per the Bank's internal asset classification list, excluding assets acquired through FDIC-assisted transactions. The allowances for loan losses reflected below are the portions of the Bank's total allowances for loan losses relating to these classified loans. There were no significant off-balance sheet items classified at December 31, 2017 and 2016.

Non-Performing Assets
The table below sets forth the amounts and categories of gross non-performing assets (classified loans which are not performing under regulatory guidelines and all foreclosed assets, including assets acquired in settlement of loans) in the Bank's loan portfolio as of the dates indicated. Loans generally are placed on non-accrual status when the loan becomes 90 days delinquent or when the collection of principal, interest, or both, otherwise becomes doubtful.
Former TeamBank, Vantus Bank, Sun Security Bank and InterBank non-performing assets, including foreclosed assets, are not included in the totals of non-performing assets below as they were subject to loss sharing agreements with the FDIC, which substantially covered principal losses that may have been incurred in these portfolios for the applicable terms under the agreements. In addition, these assets were initially recorded at their fair value estimated fair values as of their acquisition dates. Former Valley Bank loans are also excluded from the totals of non-performing assets below, although they are not covered by a loss sharing agreement. As in the previous FDIC-assisted acquisitions, former Valley Bank loans are accounted for in pools and were recorded at their fair value at the time of the acquisition as of June 20, 2014; therefore, these loan pools are analyzed rather than the individual loans. The overall performance of the FDIC-covered acquired loan pools has been better than original expectations as of the acquisition dates. At December 31, 2017, there were no material non-performing assets in these acquired loan portfolios.

Gross impaired loans totaled $25.3 million at December 31, 2017 and $34.3 million at December 31, 2016. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due.

Allowances for Losses on Loans and Foreclosed Assets
Great Southern maintains an allowance for loan losses to absorb losses known and inherent in the loan portfolio based upon ongoing, monthly assessments of the loan portfolio. Our methodology for assessing the appropriateness of the allowance consists of several key elements, which include a formula allowance, specific allowances for identified problem loans and portfolio segments and economic conditions that may lead to a concern about the loan portfolio or segments of the loan portfolio.
35

The formula allowance is calculated by applying loss factors to outstanding loans based on the internal risk evaluation of such loans or pools of loans. Changes in risk evaluations of both performing and non-performing loans affect the amount of the formula allowance. Loss factors are based both on our historical loss experience and on significant factors that, in management's judgment, affect the collectability of the portfolio as of the evaluation date. Loan loss factors for portfolio segments are representative of the credit risks associated with loans in those segments. The greater the credit risks associated with a particular segment, the greater the loss factor.
The appropriateness of the allowance is reviewed by management based upon its evaluation of then-existing economic and business conditions affecting our key lending areas. Other conditions that management considers in determining the appropriateness of the allowance include, but are not limited to, changes to our underwriting standards (if any), credit quality trends (including changes in non-performing loans expected to result from existing economic and other market conditions), trends in collateral values, loan volumes and concentrations, and recent loss experience in particular segments of the portfolio that existed as of the balance sheet date and the impact that such conditions were believed to have had on the collectability of those loans.
Senior management reviews these conditions regularly in discussions with our credit officers. To the extent that any of these conditions are evident in a specifically identifiable problem loan or portfolio segment as of the evaluation date, management's estimate of the effect of such condition may be reflected as a specific allowance applicable to such loan or portfolio segment. Where any of these conditions are not evident in a specifically identifiable problem loan or portfolio segment as of the evaluation date, management's evaluation of the loss related to these conditions is reflected in the general allowance associated with our loan portfolio. The evaluation of the inherent loss with respect to these conditions is subject to a higher degree of uncertainty because they are not identified with specific problem loans or portfolio segments.
The amounts actually observed in respect of these losses can vary significantly from the estimated amounts. Our methodology permits adjustments to any loss factor used in the computation of the formula allowances in the event that, in management's judgment, significant factors which affect the collectability of the portfolio, as of the evaluation date, are not reflected in the current loss factors. By assessing the estimated losses inherent in our loan portfolio on a monthly basis, we can adjust specific and inherent loss estimates based upon more current information.
On a quarterly basis, senior management presents a formal assessment of the adequacy of the allowance for loan losses to Great Southern's board of directors for the board's approval of the allowance. Assessing the adequacy of the allowance for loan losses is inherently subjective as it requires making material estimates including the amount and timing of future cash flows expected to be received on impaired loans or changes in the market value of collateral securing loans that may be susceptible to significant change. In the opinion of management, the allowance when taken as a whole is adequate to absorb reasonable estimated loan losses inherent in Great Southern's loan portfolio.
Allowances for estimated losses on foreclosed assets (real estate and other assets acquired through foreclosure) are charged to expense, when in the opinion of management, any significant and permanent decline in the market value of the underlying asset reduces the market value to less than the carrying value of the asset. Senior management assesses the market value of each foreclosed asset individually on a regular basis.
At December 31, 2017 and 2016, Great Southern had an allowance for losses on loans of $36.5 million and $37.4 million, respectively, of which $4.0 million and $6.4 million, respectively, had been allocated for specific loans. All loans with specific allowances were considered to be impaired loans. The allowance and the activity within the allowance during 2017, 2016 and 2015 are discussed further in Note 3 "Loans and Allowance for Loan Losses" of the accompanying audited financial statements and "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in Item 8 and Item 7 of this Report, respectively.

On at least a quarterly basis, the Company evaluates the securities portfolio to determine if an other-than-temporary impairment (OTTI) needs to be recorded. For debt securities with fair values below carrying value, when the Company does not intend to sell a debt security, and it is more likely than not the Company will not have to sell the security before recovery of its cost basis, it recognizes the credit component of an OTTI of a debt security in earnings and the remaining portion in other comprehensive income. For held-to-maturity debt securities, the amount of an OTTI recorded in other comprehensive income for the noncredit portion of a previous OTTI is amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security. During 2017, 2016 and 2015, no securities were determined to have impairment that had become other than temporary.
40

The Company's consolidated statements of income as of December 31, 2017, 2016 and 2015, reflect the full impairment (that is, the difference between the security's amortized cost basis and fair value) on debt securities that the Company intends to sell or would more likely than not be required to sell before the expected recovery of the amortized cost basis. For available-for-sale and held-to-maturity debt securities that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections.
For equity securities, if any, when the Company has decided to sell an impaired available-for-sale security and the Company does not expect the fair value of the security to fully recover before the expected time of sale, the security is deemed other-than-temporarily impaired in the period in which the decision to sell is made. The Company recognizes an impairment loss when the impairment is deemed other than temporary even if a decision to sell has not been made.
Sources of Funds
General. Deposit accounts have traditionally been the principal source of the Bank's funds for use in lending and for other general business purposes. In addition to deposits, the Bank obtains funds through advances from the Federal Home Loan Bank of Des Moines ("FHLBank") and other borrowings, loan repayments, loan sales, and cash flows generated from operations. Scheduled loan payments are a relatively stable source of funds, while deposit inflows and outflows and the related costs of such funds have varied widely. Borrowings such as FHLBank advances may be used on a short-term basis to compensate for seasonal reductions in deposits or deposit inflows at less than projected levels and may be used on a longer-term basis to support expanded lending activities. The availability of funds from loan sales is influenced by general interest rates as well as the volume of originations.
Deposits. The Bank attracts both short-term and long-term deposits from the general public by offering a wide variety of accounts and rates and also purchases brokered deposits from time to time. The Bank offers regular savings accounts, checking accounts, various money market accounts, fixed-interest rate certificates with varying maturities, certificates of deposit in minimum amounts of $100,000 ("Jumbo" accounts), brokered certificates and individual retirement accounts. In 2015, the Bank increased its deposits through internal growth, primarily in interest-bearing demand and savings deposits and non-interest-bearing demand accounts. Additionally in 2015, the Bank increased its brokered deposits by $110 million. The deposit growth and cash flows from payments on investment securities were used to fund the Bank's loan growth. In 2016, the Bank increased its deposits through internal growth and the assumption of deposits in a branch acquisition. Additionally in 2016, the Bank increased its brokered deposits by $40 million. In 2017, the Bank increased its in interest-bearing demand and savings deposits and non-interest-bearing demand deposits through internal growth. Additionally in 2017, the Bank decreased its brokered deposits by $64 million and decreased its time deposits in denominations of $100,000 or more by $36 million.
The following table sets forth the dollar amount of deposits, by interest rate range, in the various types of deposit programs offered by the Bank at the dates indicated.

A table showing maturity information for the Bank's time deposits as of December 31, 2017, is presented in Note 8 of the accompanying audited financial statements, which are included in Item 8 of this Report.
The variety of deposit accounts offered by the Bank has allowed it to be competitive in obtaining funds and has allowed it to respond with flexibility to changes in consumer demand. The Bank has become more susceptible to short-term fluctuations in deposit flows, as customers have become more interest rate conscious and the Bank's deposit mix has changed to a smaller percentage of time deposits. The Bank manages the pricing of its deposits in keeping with its asset/liability management and profitability objectives. Based on its experience, management believes that its certificate accounts are relatively stable sources of deposits, while its checking accounts have proven to be more volatile. In the past three years, the Bank has focused on growing its checking accounts both internally and through acquisitions. The ability of the Bank to attract and maintain deposits, and the rates paid on these deposits, has been and will continue to be significantly affected by money market conditions.
The following table sets forth the time remaining until maturity of the Bank's time deposits as of December 31, 2017. The table is based on information prepared in accordance with generally accepted accounting principles.

(1) | Deposits from governmental and other public entities.

Brokered deposits. Brokered deposits are marketed through national brokerage firms to their customers in $1,000 increments. The Bank maintains only one account for the total deposit amount while the detailed records of owners are maintained by the Depository Trust Company under the name of CEDE & Co. The deposits are transferable just like a stock or bond investment and the customer can open the account with only a phone call or an online request. This provides a large deposit for the Bank at a lower operating cost since the Bank only has one account to maintain versus several accounts with multiple interest and maturity dates. At December 31, 2017 and 2016, the Bank had approximately $260.0 million and $324.3 million in brokered deposits, respectively.
Included in the brokered deposits total at December 31, 2017 and 2016, was $34.5 million and $14.0 million, respectively, in Certificate of Deposit Account Registry Service (CDARS) customer deposit accounts. CDARS customer deposit accounts are accounts that are just like any other deposit account on the Company's books, except that the account total exceeds the FDIC deposit insurance maximum. When a customer places a large deposit with a CDARS Network bank, that bank uses CDARS to place the funds into deposit accounts issued by other banks in the CDARS Network. This occurs in increments of less than the standard FDIC insurance maximum, so that both principal and interest are eligible for complete FDIC protection. Other Network members do the same thing with their customers' funds. Also included in the brokered deposits total at December 31, 2017 and 2016, was $153.0 million and $147.3 million, respectively, in CDARS purchased funds accounts. CDARS purchased funds transactions represent an easy, cost-effective source of funding without collateralization or credit limits for the Company. Purchased funds transactions help the Company obtain large blocks of funding while providing control over pricing and diversity of wholesale funding options. Purchased funds transactions are obtained through a bid process that occurs weekly, with varying maturity terms.
Unlike non-brokered deposits where the deposit amount can be withdrawn prior to maturity with a penalty for any reason, including increasing interest rates, a brokered deposit (excluding CDARS) can only be withdrawn in the event of the death, or court declared mental incompetence, of the depositor. This allows the Bank to better manage the maturity of its deposits. Currently, the rates offered by the Bank for brokered deposits are somewhat higher than that offered for retail certificates of deposit of similar size and maturity. Because the Bank had kept higher levels of liquidity since the economic recession began in 2008, we had gradually reduced the amount of brokered deposits (excluding CDARS) utilized since December 31, 2008. As loan demand began to increase since 2013, we began to gradually increase our usage of brokered deposits again from time to time.
42

The Company may use interest rate swaps from time to time to manage its interest rate risks from recorded financial liabilities. In the past, the Company entered into interest rate swap agreements with the objective of economically hedging against the effects of changes in the fair value of its liabilities for fixed rate brokered certificates of deposit caused by changes in market interest rates. These interest rate swaps allowed the Company to create funding of varying maturities at a variable rate that in the past has approximated three-month LIBOR. The Company did not utilize these types of interest rate swaps in 2017, 2016 or 2015.
Borrowings. Great Southern's other sources of funds include advances from the FHLBank, a Qualified Loan Review ("QLR") arrangement with the FRB, customer repurchase agreements and other borrowings.
As a member of the FHLBank, the Bank is required to own capital stock in the FHLBank and is authorized to apply for advances from the FHLBank. Each FHLBank credit program has its own interest rate, which may be fixed or variable, and range of maturities. The FHLBank may prescribe the acceptable uses for these advances, as well as other risks on availability, limitations on the size of the advances and repayment provisions. At December 31, 2017 and 2016, the Bank's FHLBank advances outstanding were $127.5 million and $31.5 million, respectively. Additionally, the Bank had outstanding overnight borrowings from the FHLBank of $15.0 million and $171.0 million at December 31, 2017 and 2016, respectively. Because they are overnight borrowings, the $15.0 million and $171.0 million are included in short-term borrowings in the Company's financial statements. The Bank utilized FHLBank advances from time to time to fund loan growth during 2016 and 2017.
The Federal Reserve Bank of St. Louis ("FRBSL") has a QLR program where the Bank can borrow on a temporary basis using commercial loans pledged to the FRBSL. Under the QLR program, the Bank can borrow any amount up to a calculated collateral value of the commercial loans pledged, for virtually any reason that creates a temporary cash need. Examples of this could be: (1) the need to fund for late outgoing wires or cash letter settlements, (2) the need to disburse one or several loans but the permanent source of funds will not be available for a few days; (3) a temporary spike in interest rates on other funding sources that are being used; or (4) the need to purchase a security for collateral pledging purposes a few days prior to the funds becoming available on an existing security that is maturing. The Bank had commercial, consumer and other loans pledged to the FRBSL at December 31, 2017 that would have allowed approximately $528.9 million to be borrowed under the above arrangement. There were no outstanding borrowings from the FRBSL at December 31, 2017 or 2016 and the facility was not used during 2017 or 2016.
The Bank enters into sales of securities under agreements to repurchase (reverse repurchase agreements). Reverse repurchase agreements are treated as financings, and the obligations to repurchase securities sold are reflected as a liability in the statements of financial condition. The dollar amount of securities underlying the agreements remains in the asset accounts. Securities underlying the agreements are being held by the Bank during the agreement period. The agreements generally are written on a one-month or less term.
In November 2006, Great Southern Capital Trust II ("Trust II"), a statutory trust formed by the Company for the purpose of issuing the securities, issued $25.0 million aggregate liquidation amount of floating rate cumulative trust preferred securities. The Trust II securities bear a floating distribution rate equal to 90-day LIBOR plus 1.60%. The Trust II securities were redeemable at the Company's option beginning in February 2012, and if not sooner redeemed, mature on February 1, 2037. The Trust II securities were sold in a private transaction exempt from registration under the Securities Act of 1933, as amended. The gross proceeds of the offering were used to purchase Junior Subordinated Debentures from the Company totaling $25.8 million and bearing an interest rate identical to the distribution rate on the Trust II securities. The initial interest rate on the Trust II debentures was 6.98%. The interest rate was 2.98% and 2.49% at December 31, 2017 and 2016, respectively.
In July 2007, Great Southern Capital Trust III ("Trust III"), a statutory trust formed by the Company for the purpose of issuing the securities, issued $5.0 million aggregate liquidation amount of floating rate cumulative trust preferred securities. The Trust III securities bore a floating distribution rate equal to 90-day LIBOR plus 1.40%. The Trust III securities were redeemable at the Company's option beginning in October 2012, and if not sooner redeemed, mature on October 1, 2037. The Trust III securities were sold in a private transaction exempt from registration under the Securities Act of 1933, as amended. The gross proceeds of the offering were used to purchase Junior Subordinated Debentures from the Company totaling $5.2 million and bearing an interest rate identical to the distribution rate on the Trust III securities.
In July 2015, the Company was the successful bidder in an auction of the $5.0 million aggregate liquidation amount of floating rate cumulative trust preferred securities issued in 2007 by Great Southern Capital Trust III. The Company purchased the trust preferred securities at a discount, which resulted in a pre-tax gain of approximately $1.1 million. Subsequent to the purchase, which resulted in the Company's ownership of all of the outstanding common and preferred securities of Great Southern Capital Trust III, such securities were canceled and the principal amount of the Company's related debentures, which had equaled the aggregate liquidation amount of the outstanding common and preferred securities of Great Southern Capital Trust III, was reduced to zero.

In 2013, the Company entered into two interest rate cap agreements for a portion of its Junior Subordinated Debentures associated with its trust preferred securities. The term of these agreements was four years with a termination date in August 2017. Under the agreements, with notional amounts of $25.0 million and $5.0 million, respectively, the Company paid interest on its Junior Subordinated Debentures in accordance with the original terms at a floating rate based on LIBOR. Should interest have risen above a certain threshold, the counterparty was to reimburse the Company for interest paid such that the Company would have an effective interest rate on the portion of its Junior Subordinated Debentures no higher than 2.37% for the first agreement and no higher than 2.17% on the second agreement. The effective portion of the gain or loss on the derivative was reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The fair value of the interest rate caps at December 31, 2017 and 2016 was $-0- and $40,000, respectively. The $5.0 million notional interest rate cap agreement was terminated when the Company purchased the related trust preferred securities in July 2015.
On August 8, 2016, the Company completed the public offering and sale of $75.0 million of its subordinated notes. The notes are due August 15, 2026, and have a fixed interest rate of 5.25% until August 15, 2021, at which time the rate becomes floating at a rate equal to three-month LIBOR plus 4.087%. The Company may call the notes at par beginning on August 15, 2021, and on any scheduled interest payment date thereafter. The notes were sold at par, resulting in net proceeds, after underwriting discounts and commissions, legal, accounting and other professional fees, of approximately $73.5 million. Total debt issuance costs, totaling approximately $1.5 million, were deferred and are being amortized over the expected life of the notes, which is 10 years. Amortization of the debt issuance costs during the years ended December 31, 2017 and 2016, totaled $151,000 and $64,000, respectively, and is included in interest expense on subordinated notes in the consolidated statements of income, resulting in an imputed interest rate of 5.47%.

Competition
The banking industry in the Company's market areas is highly competitive. In addition to competing with other commercial and savings banks, the Company competes with credit unions, finance companies, leasing companies, mortgage companies, insurance companies, brokerage and investment banking firms and many other financial service firms. Competition is based on a number of factors including, among others, customer service, quality and range of products and services offered, price, reputation, interest rates on loans and deposits, lending limits and customer convenience. Our ability to continue to compete effectively also depends in large part on our ability to attract new employees and retain and motivate our existing employees, while managing compensation and other costs.
A substantial number of the commercial banks operating in most of the Company's market areas are branches or subsidiaries of large organizations affiliated with statewide, regional or national banking companies and as a result they may have greater resources with which to compete. Additionally, the Company faces competition from a large number of community banks, many of which have senior management who were previously with other local banks or investor groups with strong local business and community ties.
The Company encounters strong competition in attracting deposits throughout its six-state retail footprint. The Company attracts a significant amount of deposits through its branch offices primarily from the communities in which those branch offices are located. Of our total 104 branch offices at the end of 2017, 70.1% of our deposit franchise dollars were located in Missouri, where our total market share at June 30, 2017, was 1.4%, or ninth in the state (based on FDIC market share deposits). The financial institutions with the top three market share positions in Missouri at June 30, 2017, were U.S. Bank, Bank of America and Scottrade Bank, which had a combined market share of 27.7%. We also have branch offices in the states of Iowa, Minnesota, Kansas, Nebraska and Arkansas which make up 15.8%, 7.3%, 4.6%, 1.6%, and 0.6% of our total deposit franchise dollars, respectively (based on our total deposits as of December 31, 2017). The Company's market share in its primary metropolitan statistical areas was as follows at June 30, 2017:

Metropolitan Statistical Area | Number of Branch Offices | Percentage of Total Market Share | Rank | Institution with Leading Market Share Position
Springfield, MO | 19 | 13.4% | 1 | Great Southern Bank
Sioux City, IA-NE-SD | 6 | 5.5% | 4 | Security National Bank of Sioux City
Davenport/Moline/Rock Island, IA-IL | 5 | 1.1% | 19 | Wells Fargo Bank
Des Moines/West Des Moines, IA | 4 | 0.5% | 31 | Wells Fargo Bank
St. Louis, MO-IL | 19 | 0.5% | 26 | Scottrade Bank
Kansas City, MO-KS | 9 | 0.4% | 36 | UMB Bank
Omaha/ Council Bluffs, NE-IA | 4 | 0.2% | 45 | First National Bank of Omaha
Fayetteville/Springdale/Rogers, AR-MO | 2 | 0.2% | 32 | Arvest Bank
Minneapolis/St. Paul/Bloomington, MN-WI | 4 | 0.1% | 30 | Wells Fargo Bank

Our most direct competition for deposits has historically come from other commercial banks, savings institutions and credit unions located in our market areas. The Bank competes for these deposits by offering a variety of deposit accounts at competitive rates, convenient business hours, and convenient branch, online, mobile and ATM services. In addition, some competitors located outside of our market areas conduct business primarily over the Internet, which may enable them to realize certain savings and offer certain deposit products and services at lower rates and with greater convenience to certain customers. Our ability to attract and retain customer deposits depends on our ability to generally provide a rate of return, liquidity and risk comparable to that offered by competing investment opportunities.
Competition in originating real estate loans comes primarily from other commercial banks, savings institutions and mortgage bankers making loans secured by real estate located in the Bank's market area. The specific institutions are similar to those discussed above in regards to deposit market share. Commercial banks and finance companies provide vigorous competition in commercial and consumer lending. The Bank competes for real estate and other loans principally on the basis of the interest rates and loan fees it charges, the types of loans it originates, the quality of services it provides to borrowers and the locations of our branch office network and loan production offices.
Many of our competitors have substantially greater resources, name recognition and market presence, which benefit them in attracting business. In addition, larger competitors (including nationwide banks that have a significant presence in our market areas) may be able to price loans and deposits more aggressively than we do because of their greater economies of scale. Smaller and newer competitors may also be more aggressive than we are in terms of pricing loan and deposit products in order to obtain a larger share of the market. In addition, some competitors located outside of our market areas conduct business primarily over the Internet, which may enable them to realize certain savings and offer products and services at more favorable rates and with greater convenience to certain customers.
49

We also depend, from time to time, on outside funding sources, including brokered deposits, where we experience nationwide competition, and Federal Home Loan Bank advances. Some of the financial institutions and financial services organizations with which we compete are not subject to the same degree of regulation as is imposed on insured depositary institutions and their holding companies. As a result, these non-bank competitors have certain advantages over us in accessing funding and in providing various services.
Despite the highly competitive environment and the challenges it presents to us, management believes the Company will continue to be competitive because of its strong commitment to quality customer service, competitive products and pricing, convenient local branches, online and mobile capabilities, and active community involvement.
Employees
At December 31, 2017, the Company and its affiliates had a total of 1,225 employees, including 290 part-time employees. None of the Company's employees are represented by any collective bargaining agreement. Management considers its employee relations to be good.
Government Supervision and Regulation
General
The Company and its subsidiaries are subject to supervision and examination by applicable federal and state banking agencies. The earnings of the Company's subsidiaries, and therefore the earnings of the Company, are affected by general economic conditions, management policies, federal and state legislation, and actions of various regulatory authorities, including the Board of Governors of the Federal Reserve System, often referred to as the Federal Reserve Board (the "FRB"), the Federal Deposit Insurance Corporation (the "FDIC") and the Missouri Division of Finance (the "MDF"). The following is a brief summary of certain aspects of the regulation of the Company and the Bank and does not purport to fully discuss such regulation. Such regulation is intended primarily for the protection of depositors and the Deposit Insurance Fund (the "DIF"), and not for the protection of stockholders.
Significant Legislation Impacting the Financial Services Industry
On July 21, 2010, sweeping financial regulatory reform legislation entitled the "Dodd-Frank Wall Street Reform and Consumer Protection Act" (the "Dodd-Frank Act") was signed into law. The Dodd-Frank Act implements far-reaching changes across the financial regulatory landscape, including provisions that, among other things:

· | Centralize responsibility for consumer financial protection by creating a new agency, the Consumer Financial Protection Bureau, with broad rulemaking authority for a wide range of consumer protection laws that apply to all banks. These laws are enforced by the Bureau for banks with more than $10 billion in assets and by the federal banking regulators for other banks.
· | Require capital rules and apply to bank holding companies and banks
· | Change the assessment base for federal deposit insurance from the amount of insured deposits to consolidated average assets less Tier 1 capital.
· | Increase the minimum ratio of net worth to insured deposits of the Deposit Insurance Fund from 1.15% to 1.35% and require the FDIC, in setting assessments, to offset the effect of the increase on institutions with assets of less than $10 billion.
· | Set out new disclosure and other requirements relating to executive compensation and corporate governance and a prohibition on compensation arrangements that encourage inappropriate risks or that could provide excessive compensation.
· | Make permanent the $250 thousand limit for federal deposit insurance.
· | Repeal the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts.
· | Increase the authority of the FRB to examine the Company and its non-bank subsidiaries.
· | Require all bank holding companies to serve as a source of financial strength to their depository institution subsidiaries in the event such subsidiaries suffer from financial distress.

Certain aspects of the Dodd-Frank Act remain subject to rulemaking and take effect over a number of years. Provisions in the legislation that affect deposit insurance assessments, and payment of interest on demand deposits could increase the costs associated with deposits. The capital requirements for the Company and the Bank could require the Company and the Bank to seek additional sources of capital in the future. See "Capital" below.

Bank Holding Company Regulation
The Company is a bank holding company that has elected to be treated as a financial holding company by the FRB. Financial holding companies are subject to comprehensive regulation by the FRB under the Bank Holding Company Act and the regulations of the FRB. The Company is required to file reports with the FRB and such additional information as the FRB may require, and is subject to regular examinations by the FRB. The FRB also has extensive enforcement authority over financial holding companies, including, among other things, the ability to assess civil money penalties, to issue cease and desist or removal orders and to require that a holding company divest subsidiaries (including its bank subsidiaries). In general, enforcement actions may be initiated for violations of law and regulations and unsafe or unsound practices.
Under FRB policy and the Dodd-Frank Act, a bank holding company must serve as a source of strength for its subsidiary banks. Accordingly, the FRB may require, and has required in the past, that a bank holding company contribute additional capital to an undercapitalized subsidiary bank.
Under the Bank Holding Company Act, a financial holding company must obtain FRB approval before: (i) acquiring, directly or indirectly, ownership or control of any voting shares of another bank or bank holding company that is not a subsidiary if, after such acquisition, it would own or control more than 5% of such shares; (ii) acquiring all or substantially all of the assets of another bank or bank or financial holding company; or (iii) merging or consolidating with another bank or financial holding company.
The Bank Holding Company Act also prohibits a financial holding company generally from engaging directly or indirectly in activities other than those involving banking, activities closely related to banking that are permitted for a bank holding company, and certain securities, insurance and merchant banking activities.
Volcker Rule
The federal banking agencies have adopted regulations to implement the provisions of the Dodd-Frank Act known as the Volcker Rule. Under the regulations, FDIC-insured depository institutions, their holding companies, subsidiaries and affiliates are generally prohibited, subject to certain exemptions, from proprietary trading of securities and other financial instruments and from acquiring or retaining an ownership interest in a "covered fund."
Trading in certain government obligations is not prohibited. These include, among others, obligations of or guaranteed by the United States or an agency or government-sponsored entity of the United States, obligations of a State of the United States or a political subdivision thereof, and municipal securities. Proprietary trading generally does not include transactions under repurchase and reverse repurchase agreements, securities lending transactions and purchases and sales for the purpose of liquidity management if the liquidity management plan meets specified criteria; nor does it generally include transactions undertaken in a fiduciary capacity.
The term "covered fund" can include, in addition to many private equity and hedge funds and other entities, certain collateralized mortgage obligations, collateralized debt obligations and collateralized loan obligations, and other items, but it does not include wholly owned subsidiaries, certain joint ventures, or loan securitizations generally if the underlying assets are solely loans. The term "ownership interest" includes not only an equity interest or a partnership interest, but also an interest that has the right to participate in selection or removal of a general partner, managing member, director, trustee or investment manager or advisor; to receive a share of income, gains or profits of the fund; to receive underlying fund assets after all other interests have been redeemed; to receive all or a portion of excess spread; or to receive income on a pass-through basis or income determined by reference to the performance of fund assets. In addition, "ownership interest" includes an interest under which amounts payable can be reduced based on losses arising from underlying fund assets.
Activities eligible for exemptions include, among others, certain brokerage, underwriting and marketing activities, and risk-mitigating hedging activities with respect to specific risks and subject to specified conditions.
Interstate Banking and Branching
Federal law allows the FRB to approve an application of a bank holding company to acquire control of, or acquire all or substantially all of the assets of, a bank located in a state other than such holding company's home state, without regard to whether the transaction is prohibited by the laws of any state. The FRB may not approve the acquisition of a bank that has not been in existence for the minimum time period (not exceeding five years) specified by the statutory law of the host state. Federal law also prohibits the FRB from approving such an application if the applicant (and its depository institution affiliates) controls or would control more than 10% of the insured deposits in the United States or if the applicant would control 30% or more of the deposits in any state in which the target bank maintains a branch and in which the applicant or any of its depository institution affiliates controls a depository institution or branch immediately prior to the acquisition of the target bank. Federal law does not affect the authority of states to limit the percentage of total insured deposits in the state which may be held or controlled by a bank or bank holding company to the extent such
51

limitation does not discriminate against out-of-state banks or bank holding companies. Individual states may also waive the 30% state-wide concentration limit. Missouri law prohibits a bank holding company from acquiring a depository institution if total deposits would exceed 13% of statewide deposits excluding bank certificates of deposit of $100,000 or more.
The federal banking agencies are generally authorized to approve interstate bank merger transactions and de novo branching without regard to whether such transactions are prohibited by the law of any state. Interstate acquisitions of branches are generally permitted only if the law of the state in which the branch is located permits such acquisitions.
As required by federal law, federal regulations prohibit any out-of-state bank from using the interstate branching authority primarily for the purpose of deposit production, including guidelines to ensure that interstate branches operated by an out-of-state bank in a host state reasonably help to meet the credit needs of the communities which they serve.
Certain Transactions with Affiliates and Other Persons
Transactions involving the Bank and its affiliates are subject to sections 23A and 23B of the Federal Reserve Act, and regulations thereunder, which impose certain quantitative limits and collateral requirements on such transactions, and require all such transactions to be on terms at least as favorable to the Bank as are available in transactions with non-affiliates.
All loans by the Bank to the principal stockholders, directors and executive officers of the Bank or any affiliate are subject to regulations restricting loans and other transactions with insiders of the Bank and its affiliates. Transactions involving such persons must be on terms and conditions comparable to those for similar transactions with non-insiders. A bank may allow favorable rate loans to insiders pursuant to an employee benefit program available to bank employees generally. The Bank has such a program.
Dividends
The FRB has issued a policy statement on the payment of cash dividends by bank holding companies, which expresses the FRB's view that a bank holding company should pay cash dividends only to the extent that its net income for the past year is sufficient to cover both the cash dividends and a rate of earnings retention that is consistent with the holding company's capital needs, asset quality and overall financial condition. The FRB also indicated that it would be inappropriate for a company experiencing serious financial problems to borrow funds to pay dividends. Furthermore, a bank holding company may be prohibited from paying any dividends if the holding company's bank subsidiary is not adequately capitalized, and dividends payable by a bank holding company and its depository institutions subsidiaries can be restricted if the capital conservation buffer requirement is not met. See "Capital" below.
A bank holding company is required to give the FRB prior written notice of any purchase or redemption of its outstanding equity securities if the gross consideration for the purchase or redemption, when combined with the net consideration paid for all such purchases or redemptions during the preceding 12 months, is equal to 10% or more of the company's consolidated net worth. The FRB may disapprove such a purchase or redemption if it determines that the proposal would constitute an unsafe or unsound practice or would violate any law, regulation, FRB order, or any condition imposed by, or written agreement with, the FRB. This notification requirement does not apply to any company that meets the well-capitalized standard for bank holding companies, is well-managed, and is not subject to any unresolved supervisory issues. Under Missouri law, the Bank may pay dividends from certain undivided profits and may not pay dividends if its capital is impaired. Dividends of the Company and the Bank may also be restricted under the capital conservation buffer rules, which became effective January 1, 2016, as discussed below under "—Capital."
Capital
Effective January 1, 2015 (with some changes phased in over several years), the Company and the Bank became subject to new capital regulations adopted by the FRB and the FDIC, which established minimum required ratios for common equity Tier 1 ("CET1") capital, Tier 1 capital and total capital and the minimum leverage ratio; set forth the risk-weightings of assets and certain off-balance sheet items for purposes of the risk-based capital ratios; require an additional capital conservation buffer over the required risk-based capital ratios, and define what qualifies as capital for purposes of meeting the capital requirements.
Under the capital regulations, the minimum capital ratios are: (1) a CET1 capital ratio of 4.5% of risk-weighted assets; (2) a Tier 1 capital ratio of 6.0% of risk-weighted assets; (3) a total risk-based capital ratio of 8.0% of risk-weighted assets; and (4) a leverage ratio (the ratio of Tier 1 capital to average total adjusted assets) of 4.0%. CET1 generally consists of common stock; retained earnings; accumulated other comprehensive income ("AOCI") unless an institution has elected to exclude AOCI from regulatory capital; and certain minority interests; all subject to applicable regulatory adjustments and deductions. Tier 1 capital generally consists of CET1 and noncumulative perpetual preferred stock. Tier 2 capital generally consists of other preferred stock and subordinated debt meeting certain conditions plus an amount of the allowance for loan and lease losses up to 1.25% of assets. Total capital is the sum of Tier 1 and Tier 2 capital.
52

A number of changes in what constitutes regulatory capital compared to the rules in effect prior to January 1, 2015 are subject to transition periods. These changes include the phasing-out of certain instruments as qualifying capital. Mortgage servicing and deferred tax assets over designated percentages of CET1 are deducted from capital. In addition, Tier 1 capital includes AOCI, which includes all unrealized gains and losses on available for sale debt and equity securities. However, because of our asset size, we were eligible for the one-time option of permanently opting out of the inclusion of unrealized gains and losses on available for sale debt and equity securities in our capital calculations. We elected this option.
For purposes of determining risk-based capital, assets and certain off-balance sheet items are risk-weighted from 0% to 1,250%, depending on the risk characteristics of the asset or item. The new regulations make certain changes in the risk-weighting of assets to better reflect credit risk and other risk exposure compared to the earlier capital rules. These include a 150% risk weight for certain high volatility commercial real estate acquisition, development and construction loans and for non-residential mortgage loans that are 90 days past due or otherwise in nonaccrual status; a 20% credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; and a 250% risk weight for mortgage servicing and deferred tax assets that are not deducted from capital.
In addition to the minimum CET1, Tier 1 and total capital ratios, the Company and the Bank must maintain a capital conservation buffer consisting of additional CET1 capital greater than 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends, repurchasing shares, and paying discretionary bonuses. The capital conservation buffer requirement began to be phased in on January 1, 2016, when a buffer greater than 0.625% of risk-weighted assets was required, which amount increases each year until the buffer requirement is fully implemented on January 1, 2019.
Under the FDIC's prompt corrective action standards, in order to be considered well-capitalized, the Bank must have a ratio of CET1 capital to risk-weighted assets of 6.5%, a ratio of Tier 1 capital to risk-weighted assets of 8%, a ratio of total capital to risk-weighted assets of 10%, and a leverage ratio of 5%; and must not be subject to any written agreement, order, capital directive, or prompt corrective action directive to meet and maintain a specific capital level for any capital measure. In order to be considered adequately capitalized, an institution must have the minimum capital ratios described above. As of December 31, 2017, the Bank was "well-capitalized." An institution that is not well-capitalized is subject to certain restrictions on brokered deposits and interest rates on deposits.
The federal banking regulators are required to take prompt corrective action if an institution fails to satisfy the requirements to qualify as adequately capitalized. All institutions, regardless of their capital levels, are restricted from making any capital distribution or paying any management fees that would cause the institution to fail to satisfy the requirements to qualify as adequately capitalized. An institution that is not at least adequately capitalized is: (i) subject to increased monitoring by the appropriate federal banking regulator; (ii) required to submit an acceptable capital restoration plan (including certain guarantees by any company controlling the institution) within 45 days; (iii) subject to asset growth limits; and (iv) required to obtain prior regulatory approval for acquisitions, branching and new lines of business. Additional restrictions and appointment of a receiver or conservator, can apply, depending on the institution's capital level. The FDIC has jurisdiction over the Bank for purposes of prompt corrective action. When the FDIC as receiver liquidates an institution, the claims of depositors and the FDIC as their successor (for deposits covered by FDIC insurance) have priority over other unsecured claims against the institution, including claims of stockholders.
To be considered "well capitalized," a bank holding company must have, on a consolidated basis, a total risk-based capital ratio of 10.0% or greater and a Tier 1 risk-based capital ratio of 6.0% or greater and must not be subject to an individual order, directive or agreement under which the FRB requires it to maintain a specific capital level. As of December 31, 2017, the Company was "well-capitalized."
The federal banking agencies take into consideration concentrations of credit risk and risks from non-traditional activities, as well as an institution's ability to manage those risks, when determining the adequacy of an institution's capital. This evaluation is generally be made as part of the institution's regular safety and soundness examination. Under their regulations, the federal banking agencies also consider interest rate risk (when the interest rate sensitivity of an institution's assets does not match the sensitivity of its liabilities or its off-balance-sheet position) in the evaluation of a bank's capital adequacy. The banking agencies have issued guidance on evaluating interest rate risk.
Although we continue to evaluate the impact that the capital rules have on the Company and the Bank, we anticipate that the Company and the Bank will remain well-capitalized, and will continue to meet the capital conservation buffer requirement.
Insurance of Accounts and Regulation by the FDIC
Great Southern is a member of the DIF, which is administered by the FDIC. Deposits are insured up to the applicable limits by the FDIC, backed by the full faith and credit of the United States Government. The general deposit insurance limit is $250,000.
53

The FDIC assesses deposit insurance premiums on all FDIC-insured institutions quarterly based on annualized rates. These premiums are assessed on an institution's total assets minus its tangible equity. Under these rules, effective July 1, 2016, assessment rates for an institution with total assets of less than $10 billion are determined by weighted average CAMELS composite ratings and certain financial ratios, and range from 3.0 to 30.0 basis, subject to certain adjustments. In an emergency, the FDIC may also impose a special assessment.
The FDIC also collects assessments from insured institutions to service the debt on bonds issued during the 1980s to resolve the thrift bailout. For the quarter ended December 31, 2017, the assessment rate was 0.54 basis points applied to the same assessment base as is used for deposit insurance assessments.
The Dodd-Frank Act establishes 1.35% as the minimum reserve ratio. The FDIC has adopted a plan under which it will meet this ratio by September 30, 2020, the deadline imposed by the Dodd-Frank Act. In addition to the statutory minimum ratio, the FDIC must designate a reserve ratio, known as the designated reserve ratio or DRR, which may exceed the statutory minimum. The FDIC has established 2.0% as the DRR. The Dodd-Frank requires the FDIC to offset the effect on institutions with assets less than $10 billion of the increase in the statutory minimum reserve ratio to 1.35% from the former statutory minimum of 1.15%. To implement the offset requirement, the FDIC has adopted a rule under which it imposes a surcharge on institutions with assets of $10 billion or more, commencing on July 1, 2016 and ending when the reserve ratio reaches 1.35%, which is expected to occur by December 31, 2018. Smaller institutions will receive credits against their deposit insurance assessments which will reduce regular assessments by 2.0 basis points for quarters when the reserve ratio is at least 1.38%.
The FDIC is authorized to conduct examinations of and to require reporting by FDIC-insured institutions, and is the primary federal banking regulator of state banks that are not members of the Federal Reserve, such as the Bank. The FDIC examines the Bank regularly. The FDIC may prohibit any insured institution from engaging in any activity the FDIC determines by regulation or order to pose a serious threat to the DIF. The FDIC also has the authority to take enforcement actions against banks and savings associations.
Federal Reserve System
The FRB requires all depository institutions to maintain reserves against their transaction accounts (primarily NOW and Super NOW checking accounts) and non-personal time deposits. At December 31, 2017, the Bank was in compliance with these reserve requirements.
Banks are authorized to borrow from the FRB "discount window," but FRB regulations only allow this borrowing for short periods of time and generally require banks to exhaust other reasonable alternative sources of funds where practical, including FHLBank advances, before borrowing from the FRB. See "Sources of Funds Borrowings" above.
Federal Home Loan Bank System
The Bank is a member of the FHLBank of Des Moines, which is one of 11 regional FHLBanks.
As a member, Great Southern is required to purchase and maintain stock in the FHLBank of Des Moines in an amount equal to the greater of 1% of its outstanding home loans or 5% of its outstanding FHLBank advances. At December 31, 2017, Great Southern had $11.2 million in FHLBank stock, which was in compliance with this requirement. In past years, the Bank has received dividends on its FHLBank stock. Over the past five years, such dividends have averaged 3.53% and were 3.63% for the year ended December 31, 2017.
Legislative and Regulatory Proposals
Any changes in the extensive regulatory scheme to which the Company or the Bank is and will be subject, whether by any of the federal banking agencies or Congress, or the Missouri legislature or MDF, could have a material effect on the Company or the Bank, and the Company and the Bank cannot predict what, if any, future actions may be taken by legislative or regulatory authorities or what impact such actions may have.
Federal and State Taxation
General
The following discussion contains a summary of certain federal and state income tax provisions applicable to the Company and the Bank. It is not a comprehensive description of the federal or state income tax laws that may affect the Company and the Bank. The following discussion is based upon current provisions of the Internal Revenue Code of 1986 (the "Code") and Treasury and judicial interpretations thereof.
54

The Company and its subsidiaries file a consolidated federal income tax return using the accrual method of accounting, with the exception of GSB Two which files a separate return as a REIT. All corporations joining in the consolidated federal income tax return are jointly and severally liable for taxes due and payable by the consolidated group. The following discussion primarily focuses upon the taxation of the Bank, since the federal income tax law contains certain special provisions with respect to banks.
Financial institutions, such as the Bank, are subject, with certain exceptions, to the provisions of the Code generally applicable to corporations.
Bad Debt Deduction
As of December 31, 2017 and 2016, retained earnings included approximately $17.5 million for which no deferred income tax liability has been recognized. This amount represents an allocation of income to bad debt deductions for tax purposes only for tax years prior to 1988. If the Bank were to liquidate, the entire amount would have to be recaptured and would create income for tax purposes only, which would be subject to the then-current corporate income tax rate. The unrecorded deferred income tax liability on the above amount was approximately $3.9 million and $6.5 million at December 31, 2017 and 2016, respectively.
The Bank is required to follow the specific charge-off method which only allows a bad debt deduction equal to actual charge-offs, net of recoveries, experienced during the fiscal year of the deduction. In a year where recoveries exceed charge-offs, the Bank would be required to include the net recoveries in taxable income.
Interest Deduction
In the case of a financial institution, such as the Bank, no deduction is allowed for the pro rata portion of its interest expense which is allocable to tax-exempt interest on obligations acquired after August 7, 1986. A limited class of tax-exempt obligations acquired after August 7, 1986 will not be subject to this complete disallowance rule. For certain tax exempt obligations issued in 2009 and 2010, an amount of tax-exempt obligations that are not generally considered part of the "limited class of tax-exempt obligations" noted above may be treated as part of the "limited class of tax-exempt obligations" to the extent of two percent of a financial institutions total assets. For tax-exempt obligations acquired after December 31, 1982 and before August 8, 1986 and for obligations acquired after August 7, 1986 that are not subject to the complete disallowance rule, 80% of interest incurred to purchase or carry such obligations will be deductible. No portion of the interest expense allocable to tax-exempt obligations acquired by a financial institution before January 1, 1983, which is otherwise deductible, will be disallowed. There are two significant changes for bonds issued in 2009 and 2010 which include (1) the annual limit for bonds that may be designated as bank qualified is increased from $10 million to $30 million and (2) the annual limitation is considered at the organization level rather than the issuer level. The interest expense disallowance rules cited above have not significantly impacted the Bank.
FDIC-Assisted Bank Transactions
During 2009, 2011 and 2012, the Bank acquired assets and liabilities of four unrelated failed institutions in transactions with the FDIC. As part of these transactions, the Bank and the FDIC entered into loss sharing agreements whereby the FDIC agreed to share losses incurred associated with the assets purchased by the Bank. In 2014, the Bank acquired assets and liabilities of an unrelated failed institution in a transaction with the FDIC. The Bank and the FDIC did not enter into a loss sharing agreement on this transaction.
The Bank recognized financial statement gains associated with these transactions. The ultimate tax treatment of these transactions is similar to the financial statement treatment; however, the approaches to valuing the acquired assets and liabilities is different, and results in carrying value differences in the underlying assets and liabilities, for tax purposes. In addition, any gain recognized on the transactions for tax purposes is recognized over a six year period.
During 2016, the Bank and the FDIC reached an agreement to terminate the loss sharing agreements associated with the 2009 and 2011 acquisition transactions. During 2017, the Bank and the FDIC reached an agreement to terminate the loss sharing agreements associated with the 2012 acquisition transaction.
Alternative Minimum Tax
Through 2017, corporations generally are subject to a 20% corporate alternative minimum tax ("AMT"). A corporation must pay the AMT to the extent it exceeds that corporation's regular federal income tax liability The AMT is imposed on "alternative minimum taxable income," defined as taxable income with certain adjustments and tax preference items, less any available exemption. Such adjustments and items include, but are not limited to, (i) net interest received on certain tax-exempt bonds issued after August 7, 1986; and (ii) 75% of the difference between adjusted current earnings and alternative minimum taxable income, as otherwise determined
55

with certain adjustments. Net operating loss carryovers may be utilized, subject to adjustment, to offset up to 90% of the alternative minimum taxable income, as otherwise determined. Any AMT paid may be credited against future regular federal income tax liabilities to the extent the regular federal income tax liability exceeds the AMT liability. In addition, certain credits may be used to reduce AMT obligations. The Company has invested in certain partnerships that generate tax credits (low-income housing and rehabilitation tax credits) that may be used to reduce their AMT.
State Taxation
Missouri-based banks, such as the Bank, are subject to a franchise tax which is imposed on the bank's taxable income at the rate of 7% of the taxable income (determined without regard for any net operating losses) - income-based calculation. Missouri-based banks are entitled to a credit against the income-based franchise tax for all other state or local taxes on banks, except taxes on real estate, unemployment taxes, bank tax, and taxes on tangible personal property owned by the Bank and held for lease or rental to others.
The Company and all subsidiaries are subject to a Missouri income tax that is imposed on the corporation's taxable income at the rate of 6.25%. The return is filed on a consolidated basis by all members of the consolidated group including the Bank, but excluding GSB Two. As a REIT, GSB Two files a separate Missouri income tax return.
The Bank also has full service offices in Kansas, Iowa, Minnesota, Nebraska and Arkansas, and has commercial loan production offices in Texas, Oklahoma and Illinois. As a result, the Bank is subject to franchise and income taxes that are imposed on the corporation's taxable income attributable to those states.
As a Maryland corporation, the Company is required to file an annual report with and pay an annual fee to the State of Maryland.
Examinations
The Company and its consolidated subsidiaries have not been audited recently by the Internal Revenue Service (IRS) and, as such, tax years through December 31, 2005, have been closed without audit. The Company, through one of its subsidiaries, is a partner in two partnerships which have been under Internal Revenue Service examination for 2006 and 2007. As a result, the Company's 2006 and subsequent tax years remain open for examination. The examinations of these partnerships advanced during 2016 and 2017. One of the partnerships has advanced to Tax Court and has entered a Motion for Entry of Decision with an agreed upon settlement. The other partnership examination was recently completed by the IRS with no change impacting the Company's tax position. The Company does not currently expect significant adjustments to its financial statements from the partnership matter at the Tax Court.
The Company is currently under State of Missouri income and franchise tax examinations for its 2014 through 2015 tax years. The Company does not currently expect significant adjustments to its financial statements from this state examination. During 2017, the Company settled its appeal with the Kansas Department of Revenue. The settlement did not result in any significant adjustments to the Company's financial statements.
Tax Reform
In the fourth quarter of 2017 the Company re-measured its deferred tax assets and liabilities as a result of the enactment of the new tax law "H.R.1," originally known as the "Tax Cuts and Jobs Act" (the "Tax Reform Legislation"). Enactment occurred on December 22, 2017. The Tax Reform Legislation became effective January 1, 2018 and modifies the tax law in many ways. The centerpiece of the Tax Reform Legislation is the reduction of the federal corporate income tax rate from 35% to 21%. All deferred tax items as of December 22, 2017 needed to be re-valued using the new federal corporate income tax rate of 21%. As a result, income tax expense recorded in 2017 included a $2.1 million reduction to deferred income tax expense.
The SEC staff issued Staff Accounting Bulletin No. 118 ("SAB 118") to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Legislation. The Company has recognized the provisional tax impact related to the revaluation of deferred tax assets and liabilities and included these amounts in its consolidated financial statements for the year ended December 31, 2017. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued, and actions the Company may take as a result of the Tax Reform Legislation. The accounting is expected to be complete when the Company's 2017 U.S. corporate income tax return is filed in 2018.

ITEM 1A. RISK FACTORS
An investment in the common stock of the Company is speculative in nature and is subject to certain risks inherent in the business of the Company and the Bank. The material risks and uncertainties that management believes affect the Company and the Bank are described below. You should carefully consider the risks described below, as well as the other information included in this Annual Report on Form 10-K, before making an investment in the Company's common stock. The risks described below are not the only ones we face in our business. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also impair our business operations. If any of the following risks occur, our business, financial condition or operating results could be materially harmed. In such an event, our common stock could decline in value.
References to "we," "us," and "our" in this "Risk Factors" section refer to the Company and its subsidiaries, including the Bank, unless otherwise specified or unless the context otherwise requires.
Risks Relating to the Company and the Bank
Difficult market conditions and economic trends have adversely affected our industry and our business.
The United States experienced a severe economic recession in 2008 and 2009. While economic growth has resumed, the rate of this growth generally has been slow through 2017. Many lending institutions, including us, experienced declines in the performance of their loans, including construction loans and commercial real estate loans, during the economic recession and for a few years after. In addition, the values of real estate collateral supporting many loans declined. The values of real estate collateral may increase or decrease over time and are subject to many factors. At times in the past, bank and bank holding company stock prices have been negatively affected, as has the ability of banks and bank holding companies to raise capital and borrow in the debt markets. Conditions such as these may have a material adverse effect on our financial condition and results of operations. In addition, as a result of the foregoing factors, there is a potential for new laws and regulations regarding lending and funding practices and capital and liquidity standards (some of which have already been proposed or implemented), and bank regulatory agencies have been and are expected to continue to be very aggressive in responding to concerns and trends identified in examinations.
Adverse developments in the financial services industry and the impact of new legislation and regulations in response to those developments could restrict our business operations, including our ability to originate loans, and adversely impact our results of operations and financial condition. Overall, during some of the past several years, the general business environment had an adverse effect on our business. The past few years have seen some areas of improvement in the general business environment; however, our business, financial condition and results of operations could be adversely affected by negative circumstances in the general business environment.
Since our business is primarily concentrated in Missouri, Iowa, Kansas and Minnesota, a significant downturn in these state or local economies, particularly in St. Louis and the Springfield, Mo. area, may adversely affect our business. We also have originated a significant dollar amount of loans in Texas and Oklahoma from our commercial loan offices in Dallas and Tulsa. A significant downturn in these state economies may adversely affect our business.
Our lending and deposit gathering activities historically were concentrated primarily in the Springfield and southwest Missouri areas. Our success continues to depend heavily on general economic conditions in Springfield and the surrounding areas. Although we believe the economy in these areas has recently been favorable relative to other areas, we do not know whether these conditions will continue. Until the past couple of years, our greatest concentration of loans and deposits has traditionally been in the Greater Springfield area. With a population of approximately 459,000, the Greater Springfield area is the third largest metropolitan area in Missouri. At December 31, 2017, approximately $385.6 million of our loan portfolio (excluding those loans acquired in FDIC-assisted transactions) consisted of loans to borrowers in or secured by properties in the Springfield, Missouri metropolitan area.
Contiguous to Springfield is the Branson, Mo. area, which is a vacation and entertainment center, attracting tourists to its lakes, theme parks, resorts, country music and novelty shows and other recreational facilities. The Branson area experienced rapid growth in the early 1990s, with stable to slightly negative growth trends occurring in the late 1990s and into the early 2000s. Branson experienced growth again in the late 2000s as a result of a large retail, hotel, and convention center project which was constructed in Branson's historic downtown. In addition, several large national retailers opened new stores in Branson. In 2010 through 2017, Branson experienced some negative growth trends with fewer visitors and the closing of some motels and shows. Residential construction has been very limited in the past few years and little net growth has occurred in Branson's commercial real estate market segments. At December 31, 2017, approximately $78.1 million of our loan portfolio (excluding those loans acquired in FDIC-assisted transactions) consisted of loans to borrowers in or secured by properties in the two-county region that includes the Branson area.
In addition to the concentrations in the southwest Missouri area, we also now have our largest concentration of loans to borrowers in or secured by properties in the St. Louis, Mo. metropolitan area. At December 31, 2017, approximately $674.0 million of our loan portfolio consisted of loans for apartments, condominiums, residential and commercial land developments, industrial revenue bonds and other types of commercial properties in the St. Louis, Mo. metropolitan area.
57

In addition to the concentrations previously discussed, we also have a concentration of loans to borrowers in or secured by properties in the States of Texas and Oklahoma. At December 31, 2017, approximately $369.6 million and $256.7 million of our loan portfolio consisted of loans primarily for various types of commercial real estate in the States of Texas and Oklahoma, respectively.
With the FDIC-assisted transactions that were completed in 2009, we now have additional concentrations of loans in Western and Central Iowa and in Eastern Kansas. The FDIC-assisted transaction completed in 2011 added to our concentrations in Missouri, particularly in St. Louis. As a result of the FDIC-assisted transaction completed in 2012, we have additional concentrations of loans in the Minneapolis, Minnesota metropolitan area. With the FDIC-assisted transaction that was completed in 2014, we now have additional loans in Eastern and Central Iowa.
Adverse changes in regional and general economic conditions could reduce our growth rate, impair our ability to collect loans, increase loan delinquencies, increase problem assets and foreclosures, increase claims and lawsuits, decrease demand for our products and services, and decrease the value of collateral for loans, especially real estate, thereby having a material adverse effect on our financial condition and results of operations. Real estate values can also be affected by governmental rules or policies and natural disasters.
Our loan portfolio possesses increased risk due to our relatively high concentration of commercial and residential construction, commercial real estate, multi-family and other commercial loans.
Our commercial and residential construction, commercial real estate, multi-family and other commercial loans accounted for approximately 78.1% of our total loan portfolio as of December 31, 2017. Generally, we consider these types of loans to involve a higher degree of risk compared to first mortgage loans on one- to four-family, owner-occupied residential properties. At December 31, 2017, we had $927.0 million of loans secured by apartments, $483.1 million of loans secured by retail-related projects, $385.5 million of loans secured by office/warehouse facilities, $247.8 million of loans secured by healthcare facilities, and $123.0 million of loans secured by motels/hotels, which are particularly sensitive to certain risks, including the following:

| · | large loan balances owed by a single borrower;

| · | payments that are dependent on the successful operation of the project; and

| · | loans that are more directly impacted by adverse conditions in the real estate market or the economy generally.

The risks associated with construction lending include the borrower's inability to complete the construction process on time and within budget, the sale of the project within projected absorption periods, the economic risks associated with real estate collateral, and the potential of a rising interest rate environment. These loans may include financing the development and/or construction of residential subdivisions. This activity may involve financing land purchases, infrastructure development (e.g., roads, utilities, etc.), as well as construction of residences or multi-family dwellings for subsequent sale by the developer/builder. Because the sale of developed properties is critical to the success of the developer's business, loan repayment may be especially subject to the volatility of real estate market values. Management has established underwriting and monitoring criteria to help minimize the inherent risks of commercial real estate construction lending. However, there is no guarantee that these controls and procedures will reduce losses on this type of lending.
Commercial and multi-family real estate lending typically involves higher loan principal amounts and the repayment of these loans generally is dependent, in large part, on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Other commercial loans are typically made on the basis of the borrower's ability to make repayment from the cash flow of the borrower's business or investment. These loans may therefore be more adversely affected by conditions in the real estate markets or in the economy generally. For example, if the cash flow from the borrower's project is reduced due to leases not being obtained or renewed, the borrower's ability to repay the loan may be impaired. In addition, many commercial and multi-family real estate loans are not fully amortized over the loan period, but have balloon payments due at maturity. A borrower's ability to make a balloon payment typically will depend on being able to either refinance the loan or complete a timely sale of the underlying property.
We plan to continue to originate commercial real estate and construction loans based on economic and market conditions. In the years prior to 2013, there was not significant demand for these types of loans. In the current economic situation, demand for these types of loans has increased and we expect to continue to originate these types of loans. Because of the increased risks related to these types of loans, we may determine it necessary to increase the level of our provision for loan losses. Increased provisions for loan losses would adversely impact our operating results. See "Item 1. Business-The Company-Lending Activities-Commercial Real Estate and Construction Lending," "-Other Commercial Lending," "-Residential Real Estate Lending" and "-Allowance for Losses on Loans and Foreclosed Assets" and "Item 7. Management's Discussion of Financial Condition and Results of Operations – Non-performing Assets" in this Report.
A slowdown in the residential or commercial real estate markets may adversely affect our earnings and liquidity position.
The overall credit quality of our construction loan portfolio is impacted by trends in real estate values. We continually monitor changes in key regional and national economic factors because changes in these factors can impact our residential and commercial
58

construction loan portfolio and the ability of our borrowers to repay their loans. Across the United States for several years, the residential real estate market experienced significant adverse trends, including accelerated price depreciation and rising delinquency and default rates, and weaknesses arose in the commercial real estate market as well. The conditions in the residential real estate market led to significant increases in loan delinquencies and credit losses as well as higher provisioning for loan losses, which in turn had a negative effect on earnings for many banks across the country. Likewise, we also experienced delinquencies in our construction loan portfolio, almost entirely related to loans originated prior to 2009. Many of these older construction projects were "build to sell" types of projects where repayment of the loans was reliant on the borrower completing the project and then selling it. Conditions of both the residential and the commercial real estate markets could negatively impact real estate values and the ability of our borrowers to liquidate properties. A lack of liquidity in the real estate market or tightening of credit standards within the banking industry could diminish sales, further reducing our borrowers' cash flows and weakening their ability to repay their debt obligations to us, which could lead to material adverse impacts on our financial condition and results of operations.
Our loan portfolio also possesses increased risk due to our concentration in consumer loans.
Consumer loans have grown from approximately $220.7 million, or 10.9% of our total loan portfolio as of December 31, 2012, to $535.9 million (this total includes $115.4 million of home equity loans), or 11.7% of our total loan portfolio as of December 31, 2017. Consumer loans may entail greater risk than do residential mortgage loans, particularly in the case of consumer loans that are unsecured or secured by rapidly depreciable assets such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation. The remaining deficiency often does not warrant further substantial collection efforts against the borrower. In addition, consumer loan collections are dependent on the borrower's continuing financial strength, and thus are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. Furthermore, the application of various federal and state laws, including federal and state consumer bankruptcy and insolvency laws, may limit the amount which can be recovered on these loans. These loans may also give rise to claims and defenses by a consumer loan borrower against an assignee of these loans such as the Bank, and a borrower may be able to assert against the assignee claims and defenses which it has against the seller of the underlying collateral.
The vast majority of our consumer loans are secured by automobiles and, to a lesser extent, boats, recreational vehicles and manufactured homes, most of which are made by us indirectly through dealers in these products. Through these dealer relationships, the dealer completes the application with the consumer and then submits it to us for credit approval. As a result, we have limited personal contact with the borrower, which creates an additional risk element for us.
Our allowance for loan losses may prove to be insufficient to absorb potential losses in our loan portfolio.
Lending money is a substantial part of our business. However, every loan we make carries a certain risk of non-payment. This risk is affected by, among other things:

| · | cash flows of the borrower and/or the project being financed;

| · | in the case of a collateralized loan, the changes and uncertainties as to the future value of the collateral;

| · | the credit history of a particular borrower;

| · | changes in economic and industry conditions; and

| · | the duration of the loan.

We maintain an allowance for loan losses that we believe reflects a reasonable estimate of known and inherent losses within the loan portfolio. We make various assumptions and judgments about the collectability of our loan portfolio. Through a periodic review and consideration of the loan portfolio, management determines the amount of the allowance for loan losses by considering general market conditions, credit quality of the loan portfolio, the collateral supporting the loans and performance of customers relative to their financial obligations with us. The amount of future losses is susceptible to changes in economic, operating and other conditions, including changes in interest rates, which may be beyond our control, and these losses may exceed current estimates. Growing loan portfolios are, by their nature, unseasoned. As a result, estimating loan loss allowances for growing portfolios is more difficult, and may be more susceptible to changes in estimates, and to losses exceeding estimates, than more seasoned portfolios. We cannot fully predict the amount or timing of losses or whether the loss allowance will be adequate in the future. Excessive loan losses and significant additions to our allowance for loan losses could have a material adverse impact on our financial condition and results of operations.
In addition, bank regulators periodically review our allowance for loan losses and may require us to increase our provision for loan losses or recognize further loan charge-offs. Any increase in our allowance for loan losses or loan charge-offs as required by these regulatory authorities might have a material adverse effect on our financial condition and results of operations.
59

We may be adversely affected by interest rate changes.
Our earnings are largely dependent upon our net interest income. Net interest income is the difference between interest income earned on interest-earning assets such as loans and securities and interest expense paid on interest-bearing liabilities such as deposits and borrowed funds. Interest rates are highly sensitive to many factors that are beyond our control, including general economic conditions and policies of various governmental and regulatory agencies, in particular, the FRB. Changes in monetary policy, including changes in interest rates, could influence not only the interest we receive on loans and securities and the amount of interest we pay on deposits and borrowings, but these changes could also affect our ability to originate loans and obtain deposits, the fair values of our financial assets and liabilities and the average duration of our loan and mortgage-backed securities portfolios. If the interest rates paid on deposits and other borrowings increase at a faster rate than the interest rates received on loans and other investments, our net interest income, and therefore earnings, could be adversely affected. In addition, a substantial portion of our loans (approximately 45.9% of our total loan portfolio as of December 31, 2017) have adjustable rates of interest. While the higher payment amounts we would receive on these loans in a rising interest rate environment may increase our interest income, some borrowers may be unable to afford the higher payment amounts, which may result in a higher rate of default. Earnings could also be adversely affected if the interest rates received on loans and other investments fall more quickly than the interest rates paid on deposits and other borrowings.
We generally seek to maintain a neutral position in terms of the volume of assets and liabilities that mature or re-price during any period. As such, we have adopted asset and liability management strategies to attempt to minimize the potential adverse effects of changes in interest rates on net interest income, primarily by altering the mix and maturity of fixed-rate and variable-rate loans, investments and funding sources, including interest rate derivatives, so that we may reasonably maintain the Company's net interest income and net interest margin. However, interest rate fluctuations, the level and shape of the interest rate yield curve, maintaining excess liquidity levels, loan prepayments, loan production and deposit flows are constantly changing and influence the ability to maintain a neutral position. Accordingly, we may not be successful in maintaining a neutral position and, as a result, our net interest margin may be adversely impacted.
The fair value of our investment securities can fluctuate due to market conditions outside of our control.
Factors beyond our control can significantly influence the fair value of securities in our investment securities portfolio and can cause potential adverse changes to the fair value of these securities. These factors include, but are not limited to, rating agency downgrades of the securities, defaults by the issuer or with respect to the underlying securities, changes in market rates of interest and instability in the credit markets. Any of these mentioned factors could cause an other-than-temporary impairment or permanent impairment of these assets, which would lead to accounting charges which could have a material negative effect on our financial condition and/or results of operations.
Conditions in the financial markets may limit our access to additional funding to meet our liquidity needs.
Liquidity is essential to our business, as we must maintain sufficient funds to respond to the needs of depositors and borrowers. An inability to raise funds through deposits, borrowings, the sale or pledging as collateral of loans and other assets could have a substantial adverse effect on our liquidity. Our access to funding sources in amounts adequate to finance our activities could be impaired by factors that affect us specifically or the financial services industry in general. Factors that could negatively affect our access to liquidity sources include a decrease in the level of our business activity due to a market downturn or regulatory action against us. Our ability to borrow could also be impaired by factors that are not specific to us, such as severe disruption of the financial markets or negative news and expectations about the prospects for the financial services industry as a whole.
Our operations may depend upon our continued ability to access brokered deposits and Federal Home Loan Bank advances.
Due to the high level of competition for deposits in our markets, we have from time to time utilized a sizable amount of certificates of deposit obtained through deposit brokers and advances from the Federal Home Loan Bank of Des Moines to help fund our asset base. Brokered deposits are marketed through national brokerage firms that solicit funds from their customers for deposit in banks, including our bank. Brokered deposits and Federal Home Loan Bank advances may generally be more sensitive to changes in interest rates and volatility in the capital markets than retail deposits attracted through our branch network, and our reliance on these sources of funds increases the sensitivity of our portfolio to these external factors. Our brokered deposits and Federal Home Loan Bank advances totaled $225.5 million and $127.5 million at December 31, 2017, compared with $310.3 million and $31.5 million at December 31, 2016. In addition to the Federal Home Loan Bank advances included here, we had overnight borrowings from the Federal Home Loan Bank totaling $15.0 million at December 31, 2017. These overnight borrowings are included in short-term borrowings in the Company's consolidated financial statements. We expect to continue to utilize brokered deposits from time to time as a supplemental funding source. In addition to these brokered deposit totals at December 31, 2017 and 2016, were Great Southern Bank customer deposits totaling $34.5 million and $14.0 million, respectively, which were part of the CDARS program which allows bank customers to maintain balances in an insured manner that would otherwise exceed the FDIC deposit insurance limit. The FDIC considers these customer accounts to be brokered deposits due to the fees paid in the CDARS program.
Bank regulators can restrict our access to these sources of funds in certain circumstances. For example, if the Bank's regulatory capital ratios declined below the "well-capitalized" status, banking regulators would require the Bank to obtain their approval prior to obtaining or renewing brokered deposits. The regulators might not approve our acceptance of brokered deposits in amounts that we
60

desire or at all. In addition, the availability of brokered deposits and the rates paid on these brokered deposits may be volatile as the balance of the supply of and the demand for brokered deposits changes. Market credit and liquidity concerns may also impact the availability and cost of brokered deposits. Similarly, Federal Home Loan Bank advances are only available to borrowers that meet certain conditions. If Great Southern were to cease meeting these conditions, our access to Federal Home Loan Bank advances could be significantly reduced or eliminated.
Certain Federal Home Loan Banks, including the Federal Home Loan Bank of Des Moines, have experienced lower earnings from time to time and paid out lower dividends to their members. Future problems at the Federal Home Loan Banks may impact the collateral necessary to secure borrowings and limit the borrowings extended to its member banks, as well as require additional capital contributions by its member banks. Should this occur, our short term liquidity needs could be negatively impacted. Should Great Southern be restricted from using FHLBank advances due to weakness in the system or with the FHLBank of Des Moines, Great Southern may be forced to find alternative funding sources. These alternative funding sources may include the utilization of existing lines of credit with third party banks or the Federal Reserve Bank along with seeking other lines of credit, borrowing under repurchase agreement lines, increasing deposit rates to attract additional funds, accessing additional brokered deposits, or selling loans or investment securities in order to maintain adequate levels of liquidity. At December 31, 2017, the Bank owned $11.2 million of stock in the FHLBank of Des Moines, which declared and paid an annualized dividend approximating 4.00% during the fourth quarter of 2017. The FHLBank of Des Moines may eliminate or reduce dividend payments at any time in the future in order for it to maintain or restore its retained earnings.
Our strategy of pursuing acquisitions exposes us to financial, execution and operational risks that could adversely affect us.
We pursue a strategy of supplementing internal growth by acquiring other financial institutions or branches that we believe will help us fulfill our strategic objectives and enhance our earnings. There are risks associated with this strategy, however, including the following:

| · | We may be exposed to potential asset quality issues or unknown or contingent liabilities of the banks or businesses we acquire. If these issues or liabilities exceed our estimates, our earnings and financial condition may be adversely affected;

| · | Prices at which acquisitions can be made fluctuate with market conditions. We have experienced times during which acquisitions could not be made in specific markets at prices our management considered acceptable and expect that we will experience this condition in the future in one or more markets;

| · | The acquisition of other entities generally requires integration of systems, procedures and personnel of the acquired entity in order to make the transaction economically feasible. This integration process is complicated and time consuming and can also be disruptive to the customers of the acquired business. If the integration process is not conducted successfully and with minimal effect on the acquired business and its customers, we may not realize the anticipated economic benefits of particular acquisitions within the expected time frame, and we may lose customers or employees of the acquired business. We may also experience greater than anticipated customer losses even if the integration process is successful;

| · | To finance an acquisition, we may borrow funds, thereby increasing our leverage and diminishing our liquidity, or raise additional capital, which could dilute the interests of our existing stockholders; and

| · | We may not be able to continue to sustain our past rate of growth or to grow at all in the future. We completed two acquisitions in 2009, one acquisition in 2011, one acquisition in 2012, one acquisition in 2014 and have opened additional banking offices and commercial loan production offices in recent years that enhanced our rate of growth. Also in 2014, acquired certain loans, deposits and branches from Boulevard Bank. In 2016, we completed our acquisition of certain loans, deposits and branches in St. Louis from Fifth Third Bank (See Note 30 of our accompanying audited financial statements included in Item 8 of this report).

Our growth or future losses may require us to raise additional capital in the future, but that capital may not be available when it is needed or the cost of that capital may be very high.
We are required by federal and state regulatory authorities to maintain adequate levels of capital to support our operations. In addition, we may elect to raise additional capital to support the growth of our business or to finance acquisitions, if any, or we may elect to raise additional capital for other reasons. Should we be required by regulatory authorities or otherwise elect to raise additional capital, we may seek to do so through the issuance of, among other things, our common stock or securities convertible into our common stock, which could dilute your ownership interest in the Company.
Our ability to raise additional capital, if needed or desired, will depend on conditions in the capital markets at that time, which are outside our control, and on our financial condition and performance. Accordingly, we cannot make assurances of our ability to raise additional capital if needed or desired, or if the terms will be acceptable to us. If we cannot raise additional capital when needed or desired, our ability to further expand our operations through internal growth and acquisitions could be materially impaired and our financial condition and liquidity could be materially adversely affected.
61

Our future success is dependent on our ability to compete effectively in the highly competitive banking industry.
We face substantial competition in all phases of our operations from a variety of different competitors. Our future growth and success will depend on our ability to compete effectively in this highly competitive environment. To date, we have grown our business successfully by focusing on our geographic market, expanding into complementary markets and emphasizing the high level of service and responsiveness desired by our customers. We compete for loans, deposits and other financial services with other commercial banks, thrifts, credit unions, consumer finance companies, insurance companies and brokerage firms. Many of our competitors offer products and services that we do not offer, and many have substantially greater resources, name recognition and market presence that benefit them in attracting business. In addition, larger competitors (including certain nationwide banks that have a significant presence in our market areas) may be able to price loans and deposits more aggressively than we do, and smaller and newer competitors may also be more aggressive in terms of pricing loan and deposit products than us in order to obtain a larger share of the market. As we have grown, we have become dependent from time to time on outside funding sources, including funds borrowed from the FHLBank of Des Moines and brokered deposits, where we face nationwide competition. Some of the financial institutions and financial services organizations with which we compete are not subject to the same degree of regulation as is imposed on insured depositary institutions and their holding companies. As a result, these non-bank competitors have certain advantages over us in accessing funding and in providing various services.
We also experience competition from a variety of institutions outside of our market areas. Some of these institutions conduct business primarily over the Internet and may thus be able to realize certain cost savings and offer products and services at more favorable rates and with greater convenience to the customer.
Our business may be adversely affected by the highly regulated environment in which we operate, including the various capital adequacy guidelines we are required to meet.
We are subject to extensive federal and state legislation, regulation, examination and supervision. Recently enacted, proposed and future legislation and regulations have had, will continue to have, or may have an adverse effect on our business and operations. For example, a federal rule which took effect on July 1, 2010 prohibits a financial institution from automatically enrolling customers in overdraft protection programs, on ATM and one-time debit card transactions, unless a consumer consents, or opts in, to the overdraft service. This rule has adversely affected, and is likely to continue to adversely affect, the results of our operations by reducing the amount of our non-interest income.
Our success depends on our continued ability to maintain compliance with the various regulations to which we are subject. Some of these regulations may increase our costs and thus place other financial institutions in stronger, more favorable competitive positions. We cannot predict what restrictions may be imposed upon us with future legislation. See "Item 1.-The Company -Government Supervision and Regulation" in this Report.
The Company and the Bank are required to meet certain regulatory capital adequacy guidelines and other regulatory requirements imposed by the FRB, the FDIC and the Missouri Division of Finance. If the Company or the Bank fails to meet these minimum capital guidelines and other regulatory requirements, our financial condition and results of operations could be materially and adversely affected and could compromise the status of the Company as a financial holding company. See "Item 1.-The Company -Government Supervision and Regulation" in this Report.
Financial reform legislation has, among other things, tightened capital standards, created a Consumer Financial Protection Bureau and resulted in regulations that have increased, and are expected to continue to increase, our costs of operations.
On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") was signed into law. This law has significantly changed the bank regulatory structure and affected the lending, deposit, investment, trading and operating activities of financial institutions and their holding companies. The Dodd-Frank Act requires various federal agencies to adopt a broad range of new implementing rules and regulations, and to prepare numerous studies and reports for Congress. The federal agencies are given significant discretion in drafting the implementing rules and regulations, and consequently, many of the details and much of the impact of the Dodd-Frank Act may not be known for many months or years.
Among the many requirements in the Dodd-Frank Act is a requirement for new capital regulations. Generally, trust preferred securities are no longer eligible as Tier 1 capital, but the Company's currently outstanding trust preferred securities were grandfathered and will continue to qualify as Tier 1 capital. See "Item 1. Business—Government Supervision and Regulation-Capital" and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations-Effect of Laws and Regulations-New Capital Rules."
The Dodd-Frank Act created the Consumer Financial Protection Bureau (the "Bureau"), with broad powers to supervise and enforce consumer protection laws. The Bureau has broad rule-making authority for a wide range of consumer protection laws that apply to all banks, including the authority to prohibit "unfair, deceptive or abusive acts and practices." The Bureau has examination and primary enforcement authority with respect to depository institutions with $10 billion or more in assets, their service providers and certain non-
62

depository entities such as debt collectors and consumer reporting agencies. In the case of banks, such as the Bank, with total assets of less than $10 billion, this examination and enforcement authority is held by the institution's primary federal banking regulator (the FDIC, in the case of the Bank).
The Bureau has finalized a number of significant rules that could have a significant impact on our business and the financial services industry more generally. In particular, the Bureau has adopted rules impacting nearly every aspect of the lifecycle of a residential mortgage loan. The Bureau has also issued guidance which could significantly affect the automotive financing industry by subjecting indirect auto lenders, such as the Bank, to regulation as creditors under the Equal Credit Opportunity Act, which would make indirect auto lenders monitor and control certain credit policies and procedures undertaken by auto dealers.
Additional provisions of the Dodd-Frank Act are described in this report under "Item 1. Business—Government Supervision and Regulation-Significant Legislation Impacting the Financial Services Industry" and "Item 7. - Management's Discussion and Analysis of Financial Condition and Results of Operations—Effect of Federal Laws and Regulations-Significant Legislation Impacting the Financial Services Industry."
Certain aspects of the Dodd-Frank Act remain subject to rulemaking and have taken and will continue to take effect over several years. Compliance with this law and its implementing regulations have resulted in and will continue to result in additional operating costs that could have a material adverse effect on our financial condition and results of operations.
The recently enacted tax reform legislation is expected to have a significant impact on us, and our financial condition and results of operations could be adversely affected by the broader implications of the legislation.
H.R. 1, which was originally known as the "Tax Cuts and Jobs Act" and was signed into law in December 2017, is expected to have a significant impact on our financial statements and customers. It will take some time for us to analyze all of the implications of this legislation. Although we generally benefit from the legislation's reduction in the Federal corporate income tax rate, a tax rate reduction potentially has broader implications for our operations, as the new rate could cause positive or negative effects on loan demand and on our pricing models, municipal bonds, tax credits and other investments. The interest deduction limitation implemented by the legislation could make some businesses and industries less inclined to borrow, potentially reducing demand for our commercial loan products. Further, the legislation's limitation on the mortgage interest deduction and state and local tax deduction for individual taxpayers could increase the after-tax cost of owning a home for some of our potential and existing customers and potentially reduce demand for, or the individual size of, the residential mortgage loans we originate.
Our exposure to operational risks may adversely affect us.
Similar to other financial institutions, we are exposed to many types of operational risk, including reputational risk, legal and compliance risk, the risk of fraud or theft by employees or outsiders, the risk that sensitive customer or Company data is compromised, unauthorized transactions by employees or operational errors, including clerical or record-keeping errors. If any of these risks occur, it could result in material adverse consequences for us.
We continually encounter technological change, and we may have fewer resources than many of our competitors to continue to invest in technological improvements.
The financial services industry is undergoing rapid technological changes, with frequent introductions of new technology-driven products and services. Our future success will depend, in part, upon our ability to address the needs of our clients by using technology to provide products and services that will satisfy client demands for convenience, as well as to create additional efficiencies in our operations. Many of our competitors have substantially greater resources to invest in technological improvements. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our clients.
We are also subject to security-related risks in connection with our use of technology, and our security measures may not be sufficient to mitigate the risk of a cyber attack or to protect us from systems failures or interruptions.
Communications and information systems are essential to the conduct of our business, as we use such systems to manage our client relationships, our general ledger and virtually all other aspects of our business. Our operations rely on the secure processing, storage, and transmission of confidential and other information in our computer systems and networks. Although we take protective measures and endeavor to modify them as circumstances warrant, the security of our computer systems, software, and networks may be vulnerable to breaches, unauthorized access, misuse, computer viruses, or other malicious code and cyber attacks that could have a security impact. If one or more of these events occur, this could jeopardize our or our clients' confidential and other information processed and stored in, and transmitted through, our computer systems and networks, or otherwise cause interruptions or malfunctions in our operations or the operations of our clients or counterparties. We may be required to expend significant additional resources to modify our protective measures or to investigate and remediate vulnerabilities or other exposures, and we may be subject to litigation and financial losses that are either not insured against or not fully covered through any insurance maintained by us. We could also suffer significant reputational damage.
63

As a service to our clients, we currently offer an Internet PC banking product and a smartphone application for iPhone and Android users. Use of these services involves the transmission of confidential information over public networks. We cannot be sure that advances in computer capabilities, new discoveries in the field of cryptography or other developments will not result in a compromise or breach in the commercially available encryption and authentication technology that we use to protect our clients' transaction data. If we were to experience such a breach or compromise, we could suffer losses and reputational damage and our results of operations could be materially adversely affected.
While we have established policies and procedures to prevent or limit the impact of systems failures and interruptions, there can be no assurance that such events will not occur or that they will be adequately addressed if they do. In addition, we outsource certain aspects of our data processing and other operational functions to certain third-party providers. If our third-party providers encounter difficulties, or if we have difficulty in communicating with them, our ability to adequately process and account for transactions could be affected, and our business operations could be adversely impacted. Threats to information security also exist in the processing of client information through various other vendors and their personnel.
The occurrence of any systems failure or interruption could damage our reputation and result in a loss of clients and business, or could expose us to legal liability. Any of these occurrences could have a material adverse effect on our results of operations.
Our accounting policies and methods impact how we report our financial condition and results of operations. Application of these policies and methods may require management to make estimates about matters that are uncertain.
Our accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. Our management must exercise judgment in selecting and applying many of these accounting policies and methods so they comply with generally accepted accounting principles and reflect management's judgment of the most appropriate manner to report our financial condition and results of operations. In some cases, management must select the accounting policy or method to apply from two or more alternatives, any of which might be reasonable under the circumstances yet might result in our reporting materially different amounts than would have been reported under a different alternative. Our significant accounting policies are described in Note 1 of the accompanying audited financial statements included in Item 8 of this Report. These accounting policies are critical to presenting our financial condition and results of operations. They may require management to make difficult, subjective or complex judgments about matters that are uncertain. Materially different amounts could be reported under different conditions or using different assumptions.
Changes in accounting standards could materially impact our consolidated financial statements.
The accounting standard setters, including the Financial Accounting Standards Board, Securities and Exchange Commission and other regulatory bodies, from time to time may change the financial accounting and reporting standards that govern the preparation of our consolidated financial statements. These changes can be hard to predict and can materially impact how we record and report our financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retroactively, resulting in changes to previously reported financial results, or a cumulative charge to retained earnings.
New accounting standards may result in a significant change to our recognition of credit losses and may materially impact our financial condition or results of operations.
In June 2016, the Financial Accounting Standards Board issued new authoritative accounting guidance under ASC Topic 326 "Financial Instruments - Credit Losses" amending the incurred loss impairment methodology in current accounting principles generally accepted in the United States of America ("GAAP") with a methodology that reflects expected credit losses (referred to as the "CECL model") and requires consideration of a broader range of reasonable and supportable information for credit loss estimates, which goes into effect for us on January 1, 2020. Under the incurred loss model, we delay recognition of losses until it is probable that a loss has been incurred. The CECL model represents a dramatic departure from the incurred loss model. The CECL model requires a financial asset (or a group of financial assets) measured at amortized cost basis, such as loans held for investment and held-to-maturity debt securities, to be presented at the net amount expected to be collected (net of the allowance for credit losses). Similarly, the credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than a write-down. In addition, the measurement of expected credit losses will take place at the time the financial asset is first added to the balance sheet (with periodic updates thereafter) and will be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount.
As such, the CECL model will materially impact how we determine our allowance for loan losses and may require us to significantly increase our allowance for loan losses. Furthermore, we may experience more fluctuations in our allowance for loan losses, which may be significant. If we were required to materially increase our allowance for loan losses, it may negatively impact our financial condition and results of operations. We are currently evaluating the new guidance and expect it to have an impact on our statements of operations and financial condition, the significance of which is not yet known. We expect the CECL model will require us to recognize a one-time cumulative adjustment to our allowance for loan losses in order to fully transition from the incurred loss model to the CECL model, which could negatively impact our financial condition and results of operations.
64

Our controls and procedures may be ineffective.
We regularly review and update our internal controls, disclosure controls and procedures and corporate governance policies and procedures. As a result, we may incur increased costs to maintain and improve our controls and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of our controls or procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business, results of operations or financial condition.
Risks Relating to our Common Stock
The price of our common stock may fluctuate significantly, and this may make it difficult for you to resell our common stock when you want or at prices you find attractive.
We cannot predict how our common stock will trade in the future. The market value of our common stock will likely continue to fluctuate in response to a number of factors including the following, most of which are beyond our control, as well as the other factors described in this "Risk Factors" section:

| · | actual or anticipated quarterly fluctuations in our operating and financial results;

| · | developments related to investigations, proceedings or litigation that involve us;

| · | changes in financial estimates and recommendations by financial analysts;

| · | dispositions, acquisitions and financings;

| · | actions of our current stockholders, including sales of common stock by existing stockholders and our directors and executive officers;

| · | fluctuations in the stock price and operating results of our competitors;

| · | regulatory developments; and

| · | other developments related to the financial services industry.

The market value of our common stock may also be affected by conditions affecting the financial markets in general, including price and trading fluctuations. These conditions may result in (i) volatility in the level of, and fluctuations in, the market prices of stocks generally and, in turn, our common stock and (ii) sales of substantial amounts of our common stock in the market, in each case that could be unrelated or disproportionate to changes in our operating performance. These broad market fluctuations may adversely affect the market value of our common stock. Our common stock also has a low average daily trading volume relative to many other stocks, which may limit an investor's ability to quickly accumulate or divest themselves of large blocks of our stock. This can lead to significant price swings even when a relatively small number of shares are being traded.
There may be future sales of additional common stock or other dilution of our equity, which may adversely affect the market price of our common stock.
We are not restricted from issuing additional common stock or preferred stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, common stock or preferred stock or any substantially similar securities. The market value of our common stock could decline as a result of sales by us of a large number of shares of common stock or preferred stock or similar securities in the market or the perception that such sales could occur.
Our board of directors is authorized to cause us to issue additional common stock, as well as classes or series of preferred stock, generally without any action on the part of the stockholders. In addition, the board has the power, generally without stockholder approval, to set the terms of any such classes or series of preferred stock that may be issued, including voting rights, dividend rights and preferences over the common stock with respect to dividends or upon the liquidation, dissolution or winding-up of our business and other terms. If we issue preferred stock in the future that has a preference over the common stock with respect to the payment of dividends or upon liquidation, dissolution or winding-up, or if we issue preferred stock with voting rights that dilute the voting power of the common stock, the rights of holders of the common stock or the market value of the common stock could be adversely affected.
Regulatory and contractual restrictions may limit or prevent us from paying dividends on and repurchasing our common stock.
Great Southern Bancorp, Inc. is an entity separate and distinct from its principal subsidiary, Great Southern Bank, and derives substantially all of its revenue in the form of dividends from that subsidiary. Accordingly, Great Southern Bancorp, Inc. is and will be dependent upon dividends from the Bank to pay the principal of and interest on its indebtedness, to satisfy its other cash needs and to pay dividends on its common and preferred stock. The Bank's ability to pay dividends is subject to its ability to earn net income and
65

to meet certain regulatory requirements. In the event the Bank is unable to pay dividends to Great Southern Bancorp, Inc., Great Southern Bancorp, Inc. may not be able to pay dividends on its common or preferred stock. Also, Great Southern Bancorp, Inc.'s right to participate in a distribution of assets upon a subsidiary's liquidation or reorganization is subject to the prior claims of the subsidiary's creditors. This includes claims under the liquidation account maintained for the benefit of certain eligible deposit account holders of the Bank established in connection with the Bank's conversion from the mutual to the stock form of ownership.
As described below in the next risk factor, the terms of our outstanding junior subordinated debt securities prohibit us from paying dividends on or repurchasing our common stock at any time when we have elected to defer the payment of interest on such debt securities or certain events of default under the terms of those debt securities have occurred and are continuing. These restrictions could have a negative effect on the value of our common stock. Moreover, holders of our common stock are entitled to receive dividends only when, as and if declared by our board of directors. Although we have historically paid cash dividends on our common stock, we are not required to do so and our board of directors could reduce, suspend or eliminate our common stock cash dividend in the future.
If we defer payments of interest on our outstanding junior subordinated debt securities or if certain defaults relating to those debt securities occur, we will be prohibited from declaring or paying dividends or distributions on, and from making liquidation payments with respect to, our common stock.
As of December 31, 2017, we had outstanding $25.8 million aggregate principal amount of junior subordinated debt securities issued in connection with the sale of trust preferred securities by one of our subsidiaries that is a statutory business trust. We have also guaranteed those trust preferred securities. The indenture governing the junior subordinated debt securities, together with the related guarantee, prohibits us, subject to limited exceptions, from declaring or paying any dividends or distributions on, or redeeming, repurchasing, acquiring or making any liquidation payments with respect to, any of our capital stock (including any preferred stock and our common stock) at any time when (i) there shall have occurred and be continuing an event of default under the indenture or any event, act or condition that with notice or lapse of time or both would constitute an event of default under the indenture; or (ii) we are in default with respect to payment of any obligations under the related guarantee; or (iii) we have deferred payment of interest on the junior subordinated debt securities. In that regard, we are entitled, at our option but subject to certain conditions, to defer payments of interest on the junior subordinated debt securities from time to time for up to five years.
Events of default under the indenture generally consist of our failure to pay interest on the junior subordinated debt securities under certain circumstances, our failure to pay any principal of or premium on the junior subordinated debt securities when due, our failure to comply with certain covenants under the indenture, and certain events of bankruptcy, insolvency or liquidation relating to us or Great Southern Bank.
As a result of these provisions, if we were to elect to defer payments of interest on the junior subordinated debt securities, or if any of the other events described in clause (i) or (ii) of the first paragraph of this risk factor were to occur, we would be prohibited from declaring or paying any dividends on our stock, from redeeming, repurchasing or otherwise acquiring any of our stock, and from making any payments to holders of our stock in the event of our liquidation, which would likely have a material adverse effect on the market value of our common stock. Moreover, without notice to or consent from our stockholders, we may issue additional series of junior subordinated debt securities in the future with terms similar to those of our existing junior subordinated debt securities or enter into other financing agreements that limit our ability to purchase or to pay dividends or distributions on our capital stock, including our common stock.
The voting limitation provision in our charter could limit your voting rights as a holder of our common stock.
Our charter provides that any person or group who acquires beneficial ownership of our common stock in excess of 10.0% of the outstanding shares may not vote the excess shares. Accordingly, if you acquire beneficial ownership of more than 10.0% of the outstanding shares of our common stock, your voting rights with respect to the common stock will not be commensurate with your economic interest in our company.
Anti-takeover provisions could adversely impact our stockholders.
Provisions in our charter and bylaws, the corporate law of the state of Maryland and federal regulations could delay or prevent a third party from acquiring us, despite the possible benefit to our stockholders, or otherwise adversely affect the market price of any class of our equity securities, including our common stock. These provisions include: a prohibition on voting shares of common stock beneficially owned in excess of 10% of total shares outstanding, supermajority voting requirements for certain business combinations with any person who beneficially owns 10% or more of our outstanding common stock; the election of directors to staggered terms of three years; advance notice requirements for nominations for election to our board of directors and for proposing matters that stockholders may act on at stockholder meetings, a requirement that only directors may fill a vacancy in our board of directors, and supermajority voting requirements to remove any of our directors. Our charter also authorizes our board of directors to issue preferred stock, and preferred stock could be issued as a defensive measure in response to a takeover proposal. In addition, because we are a bank holding company, purchasers of 10% or more of our common stock may be required to obtain approvals under the Change in Bank Control Act of 1978, as amended, or the Bank Holding Company Act of 1956, as amended (and in certain cases such approvals may be required at a lesser percentage of ownership). Specifically, under regulations adopted by the Federal Reserve Board, (a) any
66

other bank holding company may be required to obtain the approval of the Federal Reserve Board to acquire or retain 5% or more of our common stock and (b) any person other than a bank holding company may be required to obtain the approval of the Federal Reserve Board to acquire or retain 10% or more of our common stock.
These provisions may discourage potential takeover attempts, discourage bids for our common stock at a premium over market price or adversely affect the market price of, and the voting and other rights of the holders of, our common stock. These provisions also could discourage proxy contests and make it more difficult for holders of our common stock to elect directors other than the candidates nominated by our board of directors.
Three members of the Turner family may exert substantial influence over the Company through their board and management positions and their ownership of the Company's stock.
The Company's Chairman of the Board, William V. Turner, and the Company's Director, President and Chief Executive Officer, Joseph W. Turner, are father and son, respectively. Julie Turner Brown, a director of the Company, is the sister of Joseph Turner and the daughter of William Turner. These three Turner family members hold three of the Company's ten Board positions. As of December 31, 2017, they collectively beneficially owned approximately 2,093,490 shares of the Company's common stock (excluding 43,250 shares underlying stock options exercisable as of or within 60 days after that date), representing approximately 14.9% of total shares outstanding, though they are subject to the voting limitation provision in our charter which precludes any person or group with beneficial ownership in excess of 10% of total shares outstanding from voting shares in excess of that threshold. Through their board and management positions and their ownership of the Company's stock, these three members of the Turner family may exert substantial influence over the direction of the Company and the outcome of Board and stockholder votes.
In addition to the Turner family members, we are aware of one other beneficial owner of more than five percent of the outstanding shares of our common stock. This beneficial owner is also a director of the Company.
As of December 31, 2017, one of the Company's directors, Earl A. Steinert, beneficially owned 936,096 shares of our common stock, representing approximately 6.6% of total shares outstanding. The shares that can be voted by the Turner family members (1,408,753 shares, per the ten percent voting limitation in our charter) and the shares beneficially owned by Mr. Steinert (936,096) total 2,344,849, representing approximately 16.6% of total shares outstanding. While they have no agreement to do so, to the extent they vote in the same manner, these stockholders may be able to exercise influence over the management and business affairs of our Company. For example, using their collective voting power, these stockholders may be able to affect the outcome of director elections or block significant transactions, such as a merger or acquisition, or any other matter that might otherwise be favored by other stockholders.

The Company's corporate offices and operations center are located in Springfield, Missouri. At December 31, 2017, the Company operated 104 retail banking centers and over 200 automated teller machines ("ATMs") in Missouri, Iowa, Minnesota, Nebraska, Kansas and Arkansas. Of the 104 banking centers, the Company owns 94 of its locations and 10 were leased for various terms. The majority of our banking center locations are in southwest and central Missouri, including the Springfield, Mo. metropolitan area, with additional concentrations in the Sioux City, Iowa, Des Moines, Iowa, Quad Cities, Iowa, Minneapolis, Minn., St. Louis Mo. and Kansas City, Mo. metropolitan areas. The ATMs are located at various banking centers and primarily convenience stores and retail centers located throughout southwest and central Missouri. At December 31, 2017, the Company also operated three commercial and one mortgage loan production offices. The Company owns one of its loan production office locations and three locations are leased.

ITEM 3. LEGAL PROCEEDINGS.
In the normal course of business, the Company and its subsidiaries are subject to pending and threatened legal actions, some of which seek substantial relief or damages. While the ultimate outcome of such legal proceedings cannot be predicted with certainty, after reviewing pending and threatened litigation with counsel, management believes at this time that, except as noted below, the outcome of such litigation will not have a material adverse effect on the Company's business, financial condition or results of operations.
On November 22, 2010, a suit was filed against the Bank in the Circuit Court of Greene County, Missouri by a customer alleging that the fees associated with the Bank's automated overdraft program in connection with its debit cards and ATM cards constitute unlawful
67

interest in violation of Missouri's usury laws. The Court certified a class of Bank customers who paid overdraft fees on their checking accounts pursuant to the Bank's automated overdraft program. On October 5, 2017, relying on a Missouri Court of Appeals decision addressing similar claims, the Court granted the Bank's motion for summary judgment and entered judgment in the Bank's favor on all of plaintiff's claims. The time for plaintiff to seek appellate review expired on November 14, 2017, with no further action taken by plaintiff.

Critical Accounting Policies, Judgments and Estimates
The accounting and reporting policies of the Company conform with accounting principles generally accepted in the United States and general practices within the financial services industry. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from those estimates.
Allowance for Loan Losses and Valuation of Foreclosed Assets
The Company believes that the determination of the allowance for loan losses involves a higher degree of judgment and complexity than its other significant accounting policies. The allowance for loan losses is calculated with the objective of maintaining an allowance level believed by management to be sufficient to absorb estimated loan losses. Management's determination of the adequacy of the allowance is based on periodic evaluations of the loan portfolio and other relevant factors. However, this evaluation is inherently subjective as it requires material estimates of, among other things, expected default probabilities, loss once loans default, expected commitment usage, the amounts and timing of expected future cash flows on impaired loans, value of collateral, estimated losses, and general amounts for historical loss experience.
The process also considers economic conditions, uncertainties in estimating losses and inherent risks in the loan portfolio. All of these factors may be susceptible to significant change. To the extent actual outcomes differ from management estimates, additional provisions for loan losses may be required which would adversely impact earnings in future periods. In addition, the Bank's regulators could require additional provisions for loan losses as part of their examination process.
Additional discussion of the allowance for loan losses is included in "Item 1. Business - Allowances for Losses on Loans and Foreclosed Assets." Inherent in this process is the evaluation of individual significant credit relationships. From time to time certain credit relationships may deteriorate due to payment performance, cash flow of the borrower, value of collateral, or other factors. In these instances, management may revise its loss estimates and assumptions for these specific credits due to changing circumstances. In some cases, additional losses may be realized; in other instances, the factors that led to the deterioration may improve or the credit may be refinanced elsewhere and allocated allowances may be released from the particular credit. In the fourth quarter of 2014, the Company began using a three-year average of historical losses for the general component of the allowance for loan loss calculation. The Company had previously used a five-year average. The Company believes that the three-year average provides a better representation of the current risks in the loan portfolio. This change was made after consultation with our regulators and third-party consultants, as well as a review of the practices used by the Company's peers. No other significant changes were made to management's overall methodology for evaluating the allowance for loan losses during the periods presented in the financial statements of this report.
In addition, the Company considers that the determination of the valuations of foreclosed assets held for sale involves a high degree of judgment and complexity. The carrying value of foreclosed assets reflects management's best estimate of the amount to be realized from the sales of the assets. While the estimate is generally based on a valuation by an independent appraiser or recent sales of similar properties, the amount that the Company realizes from the sales of the assets could differ materially from the carrying value reflected in the financial statements, resulting in losses that could adversely impact earnings in future periods.
Carrying Value of Loans Acquired in FDIC-assisted Transactions and Indemnification Asset
The Company considers that the determination of the carrying value of loans acquired in the FDIC-assisted transactions and the carrying value of the related FDIC indemnification asset involves a high degree of judgment and complexity. The carrying value of the acquired loans and, prior to June 30, 2017, the FDIC indemnification asset reflect management's best ongoing estimates of the amounts to be realized on each of these assets. The Company has now terminated all loss sharing agreements with the FDIC and, accordingly, no longer has an indemnification asset. The Company determined initial fair value accounting estimates of the acquired assets and assumed liabilities in accordance with FASB ASC 805, Business Combinations. However, the amount that the Company realizes on its acquired loan assets could differ materially from the carrying value reflected in its financial statements, based upon the timing of collections on the acquired loans in future periods. Because of the loss sharing agreements with the FDIC on certain of these assets, the Company did not expect to incur any significant losses related to these assets. To the extent the actual values realized for the acquired loans are different from the estimates, the indemnification asset was generally impacted in an offsetting manner due to the loss sharing support from the FDIC. Subsequent to the initial valuation, the Company continues to monitor identified loan pools for changes in estimated cash flows projected for the loan pools, anticipated credit losses and changes in the accretable yield. Analysis of these variables requires significant estimates and a high degree of judgment. See Note 4 of the accompanying audited financial statements for additional information regarding the TeamBank, Vantus Bank, Sun Security Bank, InterBank and Valley Bank FDIC-assisted transactions.

Goodwill and Intangible Assets
Goodwill and intangible assets that have indefinite useful lives are subject to an impairment test at least annually and more frequently if circumstances indicate their value may not be recoverable. Goodwill is tested for impairment using a process that estimates the fair value of each of the Company's reporting units compared with its carrying value. The Company defines reporting units as a level below each of its operating segments for which there is discrete financial information that is regularly reviewed. As of December 31, 2017, the Company has one reporting unit to which goodwill has been allocated – the Bank. If the fair value of a reporting unit exceeds its carrying value, then no impairment is recorded. If the carrying value amount exceeds the fair value of a reporting unit, further testing is completed comparing the implied fair value of the reporting unit's goodwill to its carrying value to measure the amount of impairment. Intangible assets that are not amortized will be tested for impairment at least annually by comparing the fair values of those assets to their carrying values. At December 31, 2017, goodwill consisted of $5.4 million at the Bank reporting unit, which included goodwill of $4.2 million that was recorded during 2016 related to the acquisition of 12 branches from Fifth Third Bank. Other identifiable intangible assets that are subject to amortization are amortized on a straight-line basis over a period of seven years. At December 31, 2017, the amortizable intangible assets consisted of core deposit intangibles of $5.4 million, including $3.2 million related to the Fifth Third Bank transaction in January 2016, $1.4 million related to the Valley Bank transaction in June 2014 and $397,000 related to the Boulevard Bank transaction in March 2014. These amortizable intangible assets are reviewed for impairment if circumstances indicate their value may not be recoverable based on a comparison of fair value. See Note 1 of the accompanying audited financial statements for additional information.
For purposes of testing goodwill for impairment, the Company used a market approach to value its reporting unit. The market approach applies a market multiple, based on observed purchase transactions for each reporting unit, to the metrics appropriate for the valuation of the operating unit. Significant judgment is applied when goodwill is assessed for impairment. This judgment may include developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables and incorporating general economic and market conditions.
Based on the Company's goodwill impairment testing, management does not believe any of its goodwill or other intangible assets are impaired as of December 31, 2017. While the Company believes no impairment existed at December 31, 2017, different conditions or assumptions used to measure fair value of the reporting unit, or changes in cash flows or profitability, if significantly negative or unfavorable, could have a material adverse effect on the outcome of the Company's impairment evaluation in the future.
Current Economic Conditions
Changes in economic conditions could cause the values of assets and liabilities recorded in the financial statements to change rapidly, resulting in material future adjustments in asset values, the allowance for loan losses, or capital that could negatively impact the Company's ability to meet regulatory capital requirements and maintain sufficient liquidity.
Following the housing and mortgage crisis and correction beginning in mid-2007, the United States entered into a significant prolonged economic downturn. Unemployment rose from 4.7% in November 2007 to peak at 10.0% in October 2009. The elevated unemployment levels negatively impacted consumer confidence, which had a detrimental impact on industry-wide performance nationally as well as in the Company's Midwest market area. Economic conditions have improved since as indicated by increasing consumer confidence levels, increased economic activity and low unemployment levels.
The national unemployment rate at December 2017 remained at 4.1% for the third consecutive month. Employment levels continued at the highest point since December 2000 and the U.S. economy added 148,000 non-farm jobs in December 2017. The health-care, construction and manufacturing sectors added the most new jobs while the retail store sector showed losses of over 67,000 during 2017, with many retailers going out of business altogether as more people shop online. The U.S. labor force participation rate (the share of working-age Americans who are either employed or are actively looking for a job) remained steady at 62.7% for the third consecutive month. As of December 2017, the unemployment rate for the Midwest, where most of the Company's business is conducted, was at 4.0%, which is in line with the national unemployment rate of 4.1%. Unemployment rates at December 31, 2017, for the states in which the Company operates were: Missouri at 3.5%, Arkansas at 3.7%, Kansas at 3.4%, Iowa at 2.8%, Nebraska at 2.7%, Minnesota at 3.1%, Illinois at 4.8%, Oklahoma at 4.1% and Texas at 3.9%. Of the metropolitan areas in which Great Southern Bank does business, the Chicago area had the highest unemployment level at 4.7% as of December 2017. The Tulsa market area unemployment rate at 4.0% was down significantly from the 5.0% rate estimated as of June 2017. The December 2017 unemployment rate at 2.8% for the Springfield market area was well below the national average. Metropolitan areas in Arkansas, Iowa, Nebraska and Minnesota had unemployment levels among the lowest in the nation.
Sales of newly built, single-family homes were at a seasonally adjusted annual rate of 625,000 units in December 2017, according to the U.S. Department of Housing and Urban Development and the U.S. Census Bureau. This represented a decrease of 9.3% from the revised November rate of 689,000 units, but 14.1% above the December 2016 estimate of 548,000 units. The inventory of new homes for sale was 295,000 at the end of December 2017, which is a 5.7 month supply at the current sales pace. In the Midwest, new home
75

sales decreased 3.1% from December 2016 to December 2017. Nationally, the median sales price of new houses sold in December 2017 was $335,400, up from $331,500 in September 2017 and $327,000 a year earlier. The average sales price was $398,900, up from $379,300 in September 2017 and $382,500 in December 2016.
In December 2017, existing home sales slipped to a seasonally adjusted annual rate of 5.57 million units from 5.78 million in November. As a whole, sales edged up 1.1% in 2017, which ended up being the best year for sales in 11 years, according to the National Association of Realtors. The national median existing home price for all housing types was $246,800 in December 2017, up 5.8% from a year ago. This marks the 70th consecutive month of year over year gains as prices reached an all-time high. The Midwest region existing home median sale price was $191,400, representing an increase of 5.8% from a year ago. Total housing inventory at the end of December 2017 has dropped for the 31st consecutive month to 1.65 million units; 10.3% lower than a year ago. Unsold inventory of existing homes as of December 2017 is a 3.2 month supply at the current sales pace, which is down from a 3.6 month supply a year ago.
The multi-family sector rebounded in 2017 after a slowdown in demand in 2016. National vacancy rates were 6.3% while our market areas reflected the following vacancy levels; Springfield, Mo. at 6.4%, St. Louis at 5.6%, Kansas City at 7.8%, Minneapolis at 4.5%, Tulsa, Okla. at 11.4%, Dallas-Fort Worth at 7.9% and Chicago at 6.7%. Despite supply-side pressure, rent growth in 2017 had not slowed materially from the previous year's pace. Demand reached its highest level on record with transaction value continuing to be strong, and cap rates appearing to have leveled off. Supply is expected to outpace demand in 2018, putting upward pressure on vacancies and slowing rent growth.
Nationally, approximately one-half of the suburban office markets are in an expansion market cycle -- characterized by decreasing vacancy rates, moderate/high new construction, high absorption, moderate/high employment growth and medium/high rental rate growth. The Company's larger market areas in the suburban office expansion market cycle include Minneapolis, Dallas-Ft. Worth, and St. Louis. Tulsa, Okla. and Kansas City are currently in the recovery market cycle -- typified by decreasing vacancy rates, low new construction, moderate absorption, low/moderate employment growth and negative/low rental rate growth. Included in the retail expansion market segment are the Company's larger market areas -- Chicago, Minneapolis, Kansas City, Dallas-Ft. Worth, and St. Louis. All of the Company's larger industrial market areas are categorized as in the expansion cycle with prospects of continuing good economic growth.
Occupancy, absorption and rental income levels of commercial real estate properties located throughout the Company's market areas remain stable according to information provided by real estate services firm CoStar Group. There continues to be moderate real estate sales and financing activity.
While current economic indicators show improvement nationally in employment, housing starts and prices, commercial real estate occupancy, absorption and rental rates, our management will continue to closely monitor regional, national and global economic conditions, as these could significantly impact our market areas.
Loss Sharing Agreements
On April 26, 2016, Great Southern Bank executed an agreement with the FDIC to terminate the loss sharing agreements for Team Bank, Vantus Bank and Sun Security Bank, effective immediately. The agreement required the FDIC to pay $4.4 million to settle all outstanding items related to the terminated loss sharing agreements. As a result of entering into the agreement, assets that were covered by the terminated loss sharing agreements, including covered loans in the amount of $61.5 million and covered other real estate owned in the amount of $468,000 as of March 31, 2016, were reclassified as non-covered assets effective April 26, 2016. In anticipation of terminating the loss sharing agreements, an impairment of the related indemnification assets was recorded during the three months ended March 31, 2016 in the amount of $584,000. On the date of the termination, the indemnification asset balances (and certain other receivables from the FDIC) related to Team Bank, Vantus Bank and Sun Security Bank, which totaled $4.4 million, net of impairment, at March 31, 2016, became $0 as a result of the receipt of funds from the FDIC as outlined in the termination agreement.
On June 9, 2017, Great Southern Bank executed an agreement with the FDIC to terminate the loss sharing agreements for InterBank, effective immediately. Pursuant to the termination agreement, the FDIC paid $15.0 million to the Bank to settle all outstanding items related to the terminated loss sharing agreements. The Company recorded a pre-tax gain on the termination of $7.7 million. As a result of entering into the termination agreement, assets that were covered by the terminated loss sharing arrangements, including covered loans in the amount of $138.8 million and covered other real estate owned in the amount of $2.9 million as of March 31, 2017, were reclassified as non-covered assets effective June 9, 2017.
The termination of the loss sharing agreements for the TeamBank, Vantus Bank, Sun Security Bank and InterBank transactions have no impact on the yields for the loans that were previously covered under these agreements, as the remaining accretable yield adjustments that affect interest income have not been changed and will continue to be recognized for all FDIC-assisted transactions in
76

the same manner as they have been previously. All post-termination recoveries, gains, losses and expenses related to these previously covered assets are recognized entirely by Great Southern Bank since the FDIC no longer shares in such gains or losses. Accordingly, the Company's future earnings are positively impacted to the extent the Company recognizes gains on any sales or recoveries in excess of the carrying value of such assets. Similarly, the Company's future earnings will be negatively impacted to the extent the Company recognizes expenses, losses or charge-offs related to such assets. There will be no future effects on non-interest income (expense) related to adjustments or amortization of the indemnification assets for TeamBank, Vantus Bank, Sun Security Bank or InterBank. All rights and obligations of the Bank and the FDIC under the terminated loss sharing agreements, including the settlement of all existing loss sharing and expense reimbursement claims, have been resolved and terminated.
General
The profitability of the Company and, more specifically, the profitability of its primary subsidiary, the Bank, depend primarily on its net interest income, as well as provisions for loan losses and the level of non-interest income and non-interest expense. Net interest income is the difference between the interest income the Bank earns on its loans and investment portfolios, and the interest it pays on interest-bearing liabilities, which consists mainly of interest paid on deposits and borrowings. Net interest income is affected by the relative amounts of interest-earning assets and interest-bearing liabilities and the interest rates earned or paid on these balances. When interest-earning assets approximate or exceed interest-bearing liabilities, any positive interest rate spread will generate net interest income.
In the year ended December 31, 2017, Great Southern's total assets decreased $136.1 million, or 3.0%, from $4.55 billion at December 31, 2016, to $4.41 billion at December 31, 2017. Full details of the current year changes in total assets are provided in the "Comparison of Financial Condition at December 31, 2017 and December 31, 2016" section.
Loans. In the year ended December 31, 2017, Great Southern's net loans decreased $33.7 million, or 0.9%, from $3.76 billion at December 31, 2016, to $3.73 billion at December 31, 2017. Contributing to the decrease in loans were reductions of $73.5 million in the FDIC-acquired loan portfolios. In addition, there were higher than usual unscheduled significant paydowns on loans during 2017. Total loan paydowns in excess of $1.0 million exceeded $600 million during 2017. Despite this, excluding FDIC-assisted acquired loans and mortgage loans held for sale, total gross loans increased $248.9 million, or 6.1%, from December 31, 2016 to December 31, 2017. This increase was primarily in construction loans, other residential (multi-family) real estate loans and commercial real estate loans. These increases were offset by decreases in consumer loans and one- to four-family residential loans. As loan demand is affected by a variety of factors, including general economic conditions, and because of the competition we face and our focus on pricing discipline and credit quality, we cannot be assured that our loan growth will match or exceed the level of increases achieved in 2017 or prior years. The Company's strategy continues to be focused on maintaining credit risk and interest rate risk at appropriate levels.
Recent loan growth has occurred in several loan types, primarily construction loans, other residential (multi-family) real estate loans and commercial real estate loans and in most of Great Southern's primary lending locations, including Springfield, St. Louis, Kansas City, Des Moines and Minneapolis, as well as the loan production offices in Chicago, Dallas and Tulsa. Certain minimum underwriting standards and monitoring help assure the Company's portfolio quality. Great Southern's loan committee reviews and approves all new loan originations in excess of lender approval authorities. Generally, the Company considers commercial construction, consumer, and commercial real estate loans to involve a higher degree of risk compared to some other types of loans, such as first mortgage loans on one- to four-family, owner-occupied residential properties. For commercial real estate, commercial business and construction loans, the credits are subject to an analysis of the borrower's and guarantor's financial condition, credit history, verification of liquid assets, collateral, market analysis and repayment ability. It has been, and continues to be, Great Southern's practice to verify information from potential borrowers regarding assets, income or payment ability and credit ratings as applicable and as required by the authority approving the loan. To minimize construction risk, projects are monitored as construction draws are requested by comparison to budget and with progress verified through property inspections. The geographic and product diversity of collateral, equity requirements and limitations on speculative construction projects help to mitigate overall risk in these loans. Underwriting standards for all loans also include loan-to-value ratio limitations which vary depending on collateral type, debt service coverage ratios or debt payment to income ratio guidelines, where applicable, credit histories, use of guaranties and other recommended terms relating to equity requirements, amortization, and maturity. Consumer loans are primarily secured by new and used motor vehicles and these loans are also subject to certain minimum underwriting standards to assure portfolio quality. Great Southern's consumer underwriting and pricing standards have been fairly consistent over the past several years through the first half of 2016. In response to a more challenging consumer credit environment, the Company tightened its underwriting guidelines on automobile lending in the latter part of 2016. Management took this step in an effort to improve credit quality in the portfolio and lower delinquencies and charge-offs. The underwriting standards employed by Great Southern for consumer loans include a determination of the applicant's payment history on other debts, credit scores, employment history and an assessment of ability to meet existing obligations and payments on the proposed loan.

Of the total loan portfolio at December 31, 2017 and 2016, 79.9% and 75.9%, respectively, was secured by real estate, as this is the Bank's primary focus in its lending efforts. At December 31, 2017 and 2016, commercial real estate and commercial construction loans were 48.0% and 42.1% of the Bank's total loan portfolio (excluding loans acquired through FDIC-assisted transactions), respectively. Commercial real estate and commercial construction loans generally afford the Bank an opportunity to increase the yield on, and the proportion of interest rate sensitive loans in, its portfolio. They do, however, present somewhat greater risk to the Bank because they may be more adversely affected by conditions in the real estate markets or in the economy generally. At December 31, 2017 and 2016, loans made in the Springfield, Mo. metropolitan statistical area (Springfield MSA) were 11% and 12% of the Bank's total loan portfolio (excluding loans acquired through FDIC-assisted transactions), respectively. The Company's headquarters are located in Springfield and we have operated in this market since 1923. Because of our large presence and experience in the Springfield MSA, many lending opportunities exist. However, if the economic conditions of the Springfield MSA were worse than those of other market areas in which we operate or the national economy overall, the performance of these loans could decline comparatively. At December 31, 2017 and 2016, loans made in the St. Louis, Mo. metropolitan statistical area (St. Louis MSA) were 19% and 19% of the Bank's total loan portfolio (excluding loans acquired through FDIC-assisted transactions), respectively. The Company's expansion into the St. Louis MSA beginning in May 2009 has provided an opportunity to not only expand its markets and provide diversification from the Springfield MSA, but also has provided access to a larger economy with increased lending opportunities despite higher levels of competition. Loans made in the St. Louis MSA are primarily commercial real estate, commercial business and multi-family residential loans which are less likely to be impacted by the higher levels of unemployment rates, as mentioned above under "Current Economic Conditions," than if the focus were on one- to four-family residential and consumer loans. For further discussions of the Bank's loan portfolio, and specifically, commercial real estate and commercial construction loans, see "Item 1. Business – Lending Activities."
The percentage of fixed-rate loans in our loan portfolio has increased from 46% as of December 31, 2010 to 54% as of December 31, 2017 due to customer preference for fixed rate loans during this period of low interest rates. The majority of the increase in fixed rate loans was in commercial construction and consumer loans, both of which typically have short durations. Of the total amount of fixed rate loans in our portfolio as of December 31, 2017, approximately 83% mature within one to five years and therefore are not considered to create significant long-term interest rate risk for the Company. Fixed rate loans make up only a portion of our balance sheet and our overall interest rate risk strategy. As of December 31, 2017, our interest rate risk models indicated a one-year interest rate earnings sensitivity position that is modestly positive in an increasing rates environment. For further discussion of our interest rate sensitivity gap and the processes used to manage our exposure to interest rate risk, see "Quantitative and Qualitative Disclosures About Market Risk – How We Measure the Risks to Us Associated with Interest Rate Changes." For discussion of the risk factors associated with interest rate changes, see "Risk Factors – We may be adversely affected by interest rate changes."
While our policy allows us to lend up to 95% of the appraised value on one-to four-family residential properties, originations of loans with loan-to-value ratios at that level are minimal. Private mortgage insurance is typically required for loan amounts above the 80% level. Few exceptions occur and would be based on analyses which determined minimal transactional risk to be involved. We consider these lending practices to be consistent with or more conservative than what we believe to be the norm for banks our size. At December 31, 2017 and 2016, an estimated 0.1% and 0.2%, respectively, of total owner occupied one- to four-family residential loans had loan-to-value ratios above 100% at origination. At December 31, 2017 and 2016, an estimated 1.5% and 1.3%, respectively, of total non-owner occupied one- to four-family residential loans had loan-to-value ratios above 100% at origination.
At December 31, 2017, troubled debt restructurings totaled $15.0 million, or 0.4% of total loans, down $6.1 million from $21.1 million, or 0.6% of total loans, at December 31, 2016. Concessions granted to borrowers experiencing financial difficulties may include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. During the years ended December 31, 2017 and 2016, respectively, no loans were restructured into multiple new loans. For further information on troubled debt restructurings, see Note 3 of the accompanying audited financial statements, which are included in Item 8 of this report.
Loans that were acquired through FDIC-assisted transactions, which are accounted for in pools, are currently included in the analysis and estimation of the allowance for loan losses. If expected cash flows to be received on any given pool of loans decreases from previous estimates, then a determination is made as to whether the loan pool should be charged down or the allowance for loan losses should be increased (through a provision for loan losses). As noted above, the loss sharing agreements for Team Bank, Vantus Bank and Sun Security Bank were terminated on April 26, 2016 and the loss sharing agreements for InterBank were terminated on June 9, 2017. Acquired loans are described in detail in Note 4 of the accompanying audited financial statements, included in Item 8 of this Report. For acquired loan pools, the Company may allocate, and at December 31, 2017, has allocated, a portion of its allowance for loan losses related to these loan pools in a manner similar to how it allocates its allowance for loan losses to those loans which are collectively evaluated for impairment.
78

The level of non-performing loans and foreclosed assets affects our net interest income and net income. We generally do not accrue interest income on these loans and do not recognize interest income until the loans are repaid or interest payments have been made for a period of time sufficient to provide evidence of performance on the loans. Generally, the higher the level of non-performing assets, the greater the negative impact on interest income and net income.
Available-for-sale Securities. In the year ended December 31, 2017, available-for-sale securities decreased $34.7 million, or 16.2%, from $213.9 million at December 31, 2016, to $179.2 million at December 31, 2017. The decrease was primarily due to calls of municipal securities and normal monthly payments received related to the portfolio of mortgage-backed securities.
Deposits. The Company attracts deposit accounts through its retail branch network, correspondent banking and corporate services areas, and brokered deposits. The Company then utilizes these deposit funds, along with FHLBank advances and other borrowings, to meet loan demand or otherwise fund its activities. In the year ended December 31, 2017, total deposit balances decreased $80.1 million, or 2.2%. Transaction account balances increased $34.8 million to $2.23 billion at December 31, 2017, while retail certificates of deposit decreased $50.6 million compared to December 31, 2016, to $1.11 billion at December 31, 2017. The increases in transaction accounts were primarily a result of increases in money market deposit accounts. Certificates of deposit opened through the Company's internet deposit acquisition channels decreased $67.3 million during 2017, as most maturing deposits were not renewed by the customer and fewer new such deposits were generated as a result of our rates intentionally not being in the top tier compared to our competitors in the internet channels. These decreases were partially offset by an increase in retail certificates generated through our banking centers. Brokered deposits, including CDARS program purchased funds, were $260.0 million at December 31, 2017, a decrease of $64.3 million from $324.3 million at December 31, 2016.
Our deposit balances may fluctuate depending on customer preferences and our relative need for funding. We do not consider our retail certificates of deposit to be guaranteed long-term funding because customers can withdraw their funds at any time with minimal interest penalty. When loan demand trends upward, we can increase rates paid on deposits to increase deposit balances and utilize brokered deposits to provide additional funding. The level of competition for deposits in our markets is high. It is our goal to gain deposit market share, particularly checking accounts, in our branch footprint. To accomplish this goal, increasing rates to attract deposits may be necessary, which could negatively impact the Company's net interest margin.
Our ability to fund growth in future periods may also depend on our ability to continue to access brokered deposits and FHLBank advances. In times when our loan demand has outpaced our generation of new deposits, we have utilized brokered deposits and FHLBank advances to fund these loans. These funding sources have been attractive to us because we can create either fixed or variable rate funding, as desired, which more closely matches the interest rate nature of much of our loan portfolio. While we do not currently anticipate that our ability to access these sources will be reduced or eliminated in future periods, if this should happen, the limitation on our ability to fund additional loans could have a material adverse effect on our business, financial condition and results of operations.
Federal Home Loan Bank Advances and Short Term Borrowings. The Company's Federal Home Loan Bank advances totaled $127.5 million at December 31, 2017, an increase of $96.0 million, or 305.4%, compared to $31.5 million at December 31, 2016. The balance of $31.5 million at December 31, 2016, which consisted of long-term advances, were repaid prior to maturity during June 2017, resulting in expense of $340,000, which is included in the Consolidated Statements of Income under "Noninterest Expense – Other operating expenses" during the year ended December 31, 2017, in order to reduce higher rate advances. The funds were replaced primarily with lower rate, short-term FHLBank advances.
Short term borrowings decreased $155.7 million from $172.3 million at December 31, 2016 to $16.6 million at December 31, 2017. The short term borrowings included overnight FHLBank borrowings of $171.0 million at December 31, 2016 and $15.0 million at December 31, 2017. The Company utilizes both overnight borrowings and short-term FHLBank advances depending on relative interest rates.
Net Interest Income and Interest Rate Risk Management. Our net interest income may be affected positively or negatively by changes in market interest rates. A large portion of our loan portfolio is tied to one-month LIBOR, three-month LIBOR or the "prime rate" and adjusts immediately or shortly after the index rate adjusts (subject to the effect of contractual interest rate floors on some of the loans, which are discussed below). We monitor our sensitivity to interest rate changes on an ongoing basis (see "Quantitative and Qualitative Disclosures About Market Risk"). In addition, our net interest income may be impacted by changes in the cash flows expected to be received from acquired loan pools. As described in Note 4 of the accompanying audited financial statements, included in Item 8 of this report, the Company's evaluation of cash flows expected to be received from acquired loan pools is on-going and increases in cash flow expectations are recognized as increases in accretable yield through interest income. Decreases in cash flow expectations are recognized as impairments through the allowance for loan losses.

The current level and shape of the interest rate yield curve poses challenges for interest rate risk management. Prior to its increase of 0.25% on December 16, 2015, the Federal Reserve Board had last changed interest rates on December 16, 2008. This was the first rate increase since September 29, 2006. The FRB has now also implemented rate increases of 0.25% on December 14, 2016, 0.25% on March 15, 2017, 0.25% on June 14, 2017 and 0.25% on December 13, 2017. Great Southern has a substantial portion of its loan portfolio ($1.31 billion at December 31, 2017) which is tied to the one-month or three-month LIBOR index and will adjust at least once within 90 days after December 31, 2017. Of these loans, $934 million had interest rate floors. Great Southern also has a significant portfolio of loans ($318 million at December 31, 2017) which are tied to a "prime rate" of interest and will adjust immediately with changes to the "prime rate" of interest. Most of these loans are tied to some national index of "prime," while a small portion is indexed to "Great Southern Bank prime" (GSB prime). The Company had elected to leave its GSB prime rate at 5.00%, but increased this rate to 5.25% in December 2015 following the FRB rate increase. The GSB prime rate was not changed following the FRB rate increase in December 2016, but was increased to 5.50% following the FRB rate increase in March 2017. The GSB prime rate was not changed following the FRB rate increase in June 2017, but was increased to 5.75% following the FRB rate increase in December 2017, and remained at that level at December 31, 2017. This does not affect a large number of customers, as there is no longer a significant portion of the loan portfolio indexed to the GSB prime rate. But for the interest rate floors, a rate cut by the FRB generally would have an anticipated immediate negative impact on the Company's net interest income due to the large total balance of loans which generally adjust immediately as the Federal Funds rate adjusts. Loans at their floor rates are, however, subject to the risk that borrowers will seek to refinance elsewhere at the lower market rate. Because the Federal Funds rate is generally low, there may also be a negative impact on the Company's net interest income due to the Company's inability to significantly lower its funding costs in the current competitive rate environment, although interest rates on assets may decline further. Conversely, interest rate increases would normally result in increased interest rates on our LIBOR-based and prime-based loans. The interest rate floors in effect may limit the immediate increase in interest rates on certain of these loans, until such time as rates rise above the floors. However, the Company may have to increase rates paid on deposits to maintain deposit balances and pay higher rates on borrowings, which could negatively impact net interest margin. The impact of the low rate environment on our net interest margin in future periods is expected to be fairly neutral. Any margin gained by rate increases on loans may be somewhat offset by reduced yields from our investment securities (to the extent investment securities are purchased) and our existing loan portfolio as payments are made and the proceeds are potentially reinvested at lower rates on new loans originated. Interest rates on certain adjustable rate loans may reset lower according to their contractual terms and index rate to which they are tied and new loans may be originated at lower market rates than the overall portfolio rate. For further discussion of the processes used to manage our exposure to interest rate risk, see "Quantitative and Qualitative Disclosures About Market Risk – How We Measure the Risks to Us Associated with Interest Rate Changes."
Non-Interest Income and Operating Expenses. The Company's profitability is also affected by the level of its non-interest income and operating expenses. Non-interest income consists primarily of service charges and ATM fees, accretion income (net of amortization) related to the FDIC-assisted acquisitions, late charges and prepayment fees on loans, gains on sales of loans and available-for-sale investments and other general operating income. In early 2016 and all of 2015, increases in the cash flows expected to be collected from the FDIC-covered loan portfolios resulted in amortization (expense) recorded relating to reductions of expected reimbursements under the loss sharing agreements with the FDIC, which were recorded as indemnification assets. This is no longer the case for the TeamBank, Vantus Bank and Sun Security Bank transactions, subsequent to April 26, 2016 (due to the termination of the related loss sharing agreements effective as of that date) and for the InterBank transaction subsequent to June 2017 (due to the termination of the related loss sharing agreements effective as of that date). Therefore, no further amortization (expense) will be recorded relating to the reductions of expected reimbursements under the loss sharing agreements with the FDIC as all Indemnification Assets and other balances due to/from the FDIC have been settled. The Company recorded a gain in non-interest income during 2017 related to the termination of the InterBank loss sharing agreements. Non-interest income may also be affected by the Company's interest rate derivative activities, if the Company chooses to implement derivatives.
Operating expenses consist primarily of salaries and employee benefits, occupancy-related expenses, expenses related to foreclosed assets, postage, FDIC deposit insurance, advertising and public relations, telephone, professional fees, office expenses and other general operating expenses. Details of the current period changes in non-interest income and non-interest expense are provided under "Results of Operations and Comparison for the Years Ended December 31, 2017 and 2016."
Business Initiatives
The Company completed several initiatives to expand and enhance the franchise in 2017.
A person-to-person (P2P) electronic payment service, called Send Money, was implemented for retail customers in February 2017. Available through the Company's smartphone mobile banking applications, the P2P service allows Great Southern debit card customers to send one-time transfers to recipients at any financial institution.
A commercial loan production office opened in April 2017 in downtown Chicago in a leased office at 2 North Riverside Plaza in the West Loop. In early 2017, a 30-year banking veteran in the Chicago area was hired to manage this office. The Company also operates commercial loan production offices in Tulsa, Okla., and Dallas.
80

The Company's chief lending officer, Steve Mitchem, retired from the Company in April 2017. Mitchem joined Great Southern in 1990. During his tenure, the Company's loan portfolio grew from $360 million primarily in the southwest Missouri region to $3.8 billion operating in nine states. Mitchem announced his retirement more than a year prior to his official retirement date to ensure a smooth management transition. At that time, the Company restructured the lending division to better reflect the Company's size and scope. The lending division has two separate areas of responsibility – loan production led by John Bugh and credit administration led by Kevin Baker. Bugh and Baker are long-term Great Southern lenders, who each have more than 28 years of banking experience.
In April 2017, Great Southern entered into a new partnership with Lenexa, Kan.-based BASYS to serve the merchant services needs of the Bank's business customers. In the partnership, BASYS provides all customer support and servicing, while Great Southern is responsible for sales production throughout the Bank's franchise. The Bank has offered merchant services solutions for many years, with the last vendor offering both sales and servicing support to customers. The relationship with BASYS represents a business model change so that Great Southern can manage the sales process with its customers.
In June 2017, Great Southern Bank entered into an agreement with the FDIC that terminated loss sharing agreements related to the Bank's 2012 acquisition of Maple Grove, Minn.-based Inter Savings Bank through an FDIC-assisted transaction. Under the termination agreement, the FDIC paid $15.0 million to the Bank to settle all outstanding items related to the terminated loss sharing agreements. More information about this termination agreement can be found in the Company's Form 10-Q for the quarter ended June 30, 2017. In April 2016, the Company executed an agreement with the FDIC to terminate loss sharing agreements related to the FDIC-assisted acquisitions of TeamBank, Vantus Bank and Sun Security Bank. More information about that termination agreement can be found in the Company's Form 10-Q for the quarter ended March 31, 2016. All loss sharing agreements related to the Bank's FDIC-assisted acquisitions have now been terminated.
At the end of October 2017, a new banking center at 1320 W. Battlefield in Springfield, Mo., opened that replaced a nearby leased office at 1580 W. Battlefield. The new office offers better access and convenience for customers.
The Company continually evaluates its various customer access channels to ensure that customers are being effectively served when, where and how they prefer. The Company's ATM network is a part of this ongoing evaluation, which may include upgrading or adding ATM units or removing units from certain sites. Starting at the end of the third quarter of 2017 and during 2018, a total of 70 ATMs located primarily at Great Southern banking centers will be replaced with upgraded multi-functional deposit-taking machines. In addition, twenty off-site ATMs with low customer usage have been removed in the last few months. Further evaluation of the ATM network is anticipated in the future. Great Southern customers can also access surcharge-free ATMs worldwide through the Allpoint ATM Network.
On January 31, 2018, the Company distributed special cash bonuses to its more than 1,200 employees, following the enactment of the new federal tax reform legislation. A $1,000 cash payment was made to all full-time employees and a $500 cash payment was made to all part-time employees who were employed by the Company on December 31, 2017, and remained employed at January 31, 2018.
Effect of Federal Laws and Regulations
General. Federal legislation and regulation significantly affect the operations of the Company and the Bank, and have increased competition among commercial banks, savings institutions, mortgage banking enterprises and other financial institutions. In particular, the capital requirements and operations of regulated banking organizations such as the Company and the Bank have been and will be subject to changes in applicable statutes and regulations from time to time, which changes could, under certain circumstances, adversely affect the Company or the Bank.
Significant Legislation Impacting the Financial Services Industry. On July 21, 2010, sweeping financial regulatory reform legislation entitled the "Dodd-Frank Wall Street Reform and Consumer Protection Act" (the "Dodd-Frank Act") was signed into law. The Dodd-Frank Act implements far-reaching changes across the financial regulatory landscape, including provisions that, among other things, centralize responsibility for consumer financial protection by creating a new agency, the Consumer Financial Protection Bureau, with broad rulemaking authority for a wide range of consumer protection laws that apply to all banks, require new capital rules (discussed below), change the assessment base for federal deposit insurance, repeal the federal prohibitions on the payment of interest on demand deposits, amend the account balance limit for federal deposit insurance protection, and increase the authority of the Federal Reserve Board to examine the Company and its non-bank subsidiaries.
Certain aspects of the Dodd-Frank Act remain subject to rulemaking and will take effect over a number of years. Provisions in the legislation that affect deposit insurance assessments and payment of interest on demand deposits could increase the costs associated with deposits. Provisions in the legislation that required revisions to the capital requirements of the Company and the Bank could require the Company and the Bank to seek additional sources of capital in the future.
81

A provision of the Dodd-Frank Act, commonly referred to as the "Durbin Amendment," directed the FRB to analyze the debit card payments system and fix the interchange rates based upon their estimate of actual costs. The FRB has established the interchange rate for all debit transactions for issuers with over $10 billion in assets at $0.21 per transaction. An additional five basis points of the transaction amount and an additional $0.01 may be collected by the issuer for fraud prevention and recovery, provided the issuer performs certain actions. The Bank is currently exempt from the rule on the basis of asset size.
Capital Rules. The federal banking agencies have adopted regulatory capital rules that substantially amended the risk-based capital rules applicable to the Bank and the Company. The new rules implement the "Basel III" regulatory capital reforms and changes required by the Dodd-Frank Act. "Basel III" refers to various documents released by the Basel Committee on Banking Supervision. For the Company and the Bank, the general effective date of the new rules was January 1, 2015, and, for certain provisions, various phase-in periods and later effective dates apply. The chief features of the new rules are summarized below.
The new rules refine the definitions of what constitutes regulatory capital and add a new regulatory capital element, common equity Tier 1 capital. The minimum capital ratios are (i) a common equity Tier 1 ("CET1") risk-based capital ratio of 4.5%; (ii) a Tier 1 risk-based capital ratio of 6%; (iii) a total risk-based capital ratio of 8%; and (iv) a Tier 1 leverage ratio of 4%. In addition to the minimum capital ratios, the new rules include a capital conservation buffer, under which a banking organization must have CET1 more than 2.5% above each of its minimum risk-based capital ratios in order to avoid restrictions on paying dividends, repurchasing shares, and paying certain discretionary bonuses. The new capital conservation buffer requirement began phasing in on January 1, 2016 when a buffer greater than 0.625% of risk-weighted assets was required, which amount increases an equal amount each year until the buffer requirement of greater than 2.5% of risk-weighted assets is fully implemented on January 1, 2019.
Effective January 1, 2015, the new rules also revised the prompt corrective action framework, which is designed to place restrictions on insured depository institutions if their capital levels show signs of weakness. Under the new prompt corrective action requirements, insured depository institutions are required to meet the following in order to qualify as "well capitalized:" (i) a common equity Tier 1 risk-based capital ratio of at least 6.5%, (ii) a Tier 1 risk-based capital ratio of at least 8%, (iii) a total risk-based capital ratio of at least 10% and (iv) a Tier 1 leverage ratio of 5%, and must not be subject to an order, agreement or directive mandating a specific capital level.
Recent Accounting Pronouncements
See Note 1 to the accompanying audited financial statements, which are included in Item 8 of this Report, for a description of recent accounting pronouncements including the respective dates of adoption and expected effects on the Company's financial position and results of operations.
Comparison of Financial Condition at December 31, 2017 and December 31, 2016
During the year ended December 31, 2017, total assets decreased by $136.1 million to $4.41 billion. The decrease was primarily attributable to decreases in cash and cash equivalents, available-for-sale investment securities, loans receivable, FDIC indemnification asset, other real estate owned and mortgage loans held for sale.
Cash and cash equivalents were $242.3 million at December 31, 2017, a decrease of $37.5 million, or 13.4%, from $279.8 million at December 31, 2016. During 2017, cash and cash equivalents decreased primarily due to a decrease in deposits and a decrease in total borrowings, partially offset by a decrease in available for sale securities.
The Company's available for sale securities decreased $34.7 million, or 16.2%, compared to December 31, 2016. The decrease was primarily due to calls of municipal securities and normal monthly payments received related to the portfolio of mortgage-backed securities. The available-for-sale securities portfolio was 4.1% and 4.7% of total assets at December 31, 2017 and 2016, respectively.
Net loans decreased $33.7 million from December 31, 2016 to $3.73 billion at December 31, 2017. Net loans acquired through the FDIC-assisted transactions decreased $73.5 million, or 26.0%, during 2017 primarily because of loan repayments. Excluding FDIC-assisted acquired loans and mortgage loans held for sale, total gross loans increased $248.9 million from December 31, 2016 to December 31, 2017. Outstanding and undisbursed balances of commercial construction loans increased $281.0 million, or 32.3%, other residential (multi-family) loans increased $82.3 million, or 12.4%, and commercial real estate loans increased $48.4 million, or 4.1%. Partially offsetting the increases in gross loans were decreases of consumer auto loans of $137.1 million, or 27.7%, and decreases of owner occupied and non-owner occupied one- to four-family residential loans of $27.3 million, or 8.1%.
The FDIC indemnification asset, which was $13.1 million at December 31, 2016, was $-0- at December 31, 2017 due to the termination during 2017 of the FDIC loss sharing agreement for InterBank, as discussed in Note 4 of the accompanying audited financial statements included in Item 8 of this report.
82

Total liabilities decreased $178.0 million from $4.12 billion at December 31, 2016 to $3.94 billion at December 31, 2017. The decrease was primarily attributable to a decrease in deposits and short-term borrowings, partially offset by an increase in FHLB advances. In the year ended December 31, 2017, total deposit balances decreased $80.1 million, or 2.2%. Retail certificates of deposit decreased $50.6 million and brokered deposits decreased $64.3 million during the year ended December 31, 2017. Transaction account balances increased $34.8 million during the year ended December 31, 2017.
The Company's Federal Home Loan Bank advances totaled $127.5 million at December 31, 2017, an increase of $96.0 million, or 305.4%, compared to $31.5 million at December 31, 2016. The balance of $31.5 million at December 31, 2016, which consisted of long-term advances, were repaid prior to maturity during June 2017, resulting in expense of $340,000, which is included in the Consolidated Statements of Income under "Noninterest Expense – Other operating expenses" during the year ended December 31, 2017. The funds were replaced during 2017 primarily with lower rate, shorter-term FHLBank advances. The Company utilizes both overnight borrowings and short-term FHLBank advances depending on relative interest rates.
Short term borrowings decreased $155.7 million from $172.3 million at December 31, 2016 to $16.6 million at December 31, 2017. The short term borrowings included overnight FHLBank borrowings of $171.0 million at December 31, 2016 and $15.0 million at December 31, 2017.
Securities sold under reverse repurchase agreements with customers decreased $33.2 million, or 29.2%, from December 31, 2016 to December 31, 2017 as these balances fluctuate over time based on customer demand for this product.
Total stockholders' equity increased $41.9 million from $429.8 million at December 31, 2016 to $471.7 million at December 31, 2017. The Company recorded net income of $51.6 million for the year ended December 31, 2017, and dividends declared on common stock were $13.2 million. Accumulated other comprehensive income decreased $317,000 due to changes in the fair value of available-for-sale investment securities. The decrease in accumulated other comprehensive income resulted from decreases in the fair value of the Company's available-for-sale investment securities and changes in the fair value of cash flow hedges. In addition, total stockholders' equity increased $3.8 million due to stock option exercises.
Results of Operations and Comparison for the Years Ended December 31, 2017 and 2016
General
Net income increased $6.3 million, or 13.7%, during the year ended December 31, 2017, compared to the year ended December 31, 2016. Net income was $51.6 million for the year ended December 31, 2017 compared to $45.3 million for the year ended December 31, 2016. This increase was due to an increase in non-interest income of $10.0 million, or 35.1%, a decrease in non-interest expense of $6.2 million, or 5.1%, and a decrease in the provision for loan losses of $181,000, or 2.0%, partially offset by a decrease in net interest income of $7.9 million, or 4.8%, and an increase in provision for income taxes of $2.2 million, or 13.6%. Net income available to common shareholders was $51.6 million for the year ended December 31, 2017 compared to $45.3 million for the year ended December 31, 2016.
Total Interest Income
Total interest income decreased $2.1 million, or 1.1%, during the year ended December 31, 2017 compared to the year ended December 31, 2016. The decrease was due to a $2.2 million, or 1.2%, decrease in interest income on loans, partially offset by a $115,000, or 1.8%, increase in interest income on investment securities and other interest-earning assets. Interest income on loans decreased in 2017 due to lower average rates of interest, partially offset by higher average balances of loans. The decrease in average interest rates on loans was primarily the result of a reduction in the additional yield accretion recognized in conjunction with updated estimates of the fair value of the acquired loan pools compared to the prior year. Interest income from investment securities and other interest-earning assets increased during 2017 compared to 2016 primarily due to higher average rates of interest, partially offset by lower average balances.
Interest Income – Loans
During the year ended December 31, 2017 compared to the year ended December 31, 2016, interest income on loans decreased due to lower average interest rates, partially offset by higher average balances. Interest income decreased $9.6 million as the result of lower average interest rates on loans. The average yield on loans decreased from 4.89% during the year ended December 31, 2016 to 4.63% during the year ended December 31, 2017. This decrease was due to a lower amount of accretion income in the current year resulting from the increases in expected cash flows to be received from the FDIC-acquired loan pools, which is discussed in Note 4 of the accompanying audited financial statements included in Item 8 of this report. The decrease was partially offset by higher overall
83

average loan balances. Interest income increased $7.4 million as the result of higher average loan balances, which increased from $3.66 billion during the year ended December 31, 2016, to $3.81 billion during the year ended December 31, 2017. The higher average balances were primarily due to organic loan growth.
On an on-going basis, the Company estimates the cash flows expected to be collected from the acquired loan pools. For each of the loan portfolios acquired, the cash flow estimates have increased, based on the payment histories and the collection of certain loans, thereby reducing loss expectations of certain loan pools, resulting in adjustments to be spread on a level-yield basis over the remaining expected lives of the loan pools. The loss sharing agreements for the Team Bank, Vantus Bank and Sun Security Bank transactions were terminated in April 2016, and the related indemnification assets were reduced to $-0- at that time. The loss sharing agreements for InterBank were terminated in June 2017, and the related indemnification asset was reduced to $-0- at that time. The Valley Bank transaction does not include a loss sharing agreement with the FDIC. Therefore, there was no remaining indemnification asset for FDIC-assisted transactions as of December 31, 2017. The entire amount of the discount adjustment has been and will be accreted to interest income over time with no further offsetting impact to non-interest income. For the years ended December 31, 2017 and 2016, the adjustments increased interest income by $5.0 million and $16.4 million, respectively, and decreased non-interest income by $634,000 and $7.0 million, respectively. The net impact to pre-tax income was $4.4 million and $9.4 million, respectively, for the years ended December 31, 2017 and 2016.
As of December 31, 2017, the remaining accretable yield adjustment that will affect interest income is $2.6 million. As there is no longer, nor will there be in the future, indemnification asset amortization related to Team Bank, Vantus Bank, Sun Security Bank or InterBank due to the termination or expiration of the related loss sharing agreements for those transactions, there is no remaining indemnification asset or related adjustments that will affect non-interest income (expense). Of the remaining adjustments affecting interest income, we expect to recognize $1.7 million of interest income during 2018. Additional adjustments may be recorded in future periods from the FDIC-assisted transactions, as the Company continues to estimate expected cash flows from the acquired loan pools. Apart from the yield accretion, the average yield on loans was 4.50% during the year ended December 31, 2017, compared to 4.44% during the year ended December 31, 2016, as a result of higher current market rates on adjustable rate loans and new loans originated during the year.
Interest Income - Investments and Other Interest-earning Assets
Interest income on investments and other interest-earning assets increased $115,000 in the year ended December 31, 2017 compared to the year ended December 31, 2016. Interest income increased $1.1 million due to an increase in average interest rates from 1.72% during the year ended December 31, 2016 to 2.05% during the year ended December 31, 2017, due to higher market rates of interest on investment securities and other interest-bearing deposits in financial institutions. Interest income decreased $1.0 million as a result of a decrease in average balances from $366.3 million during the year ended December 31, 2016, to $329.4 million during the year ended December 31, 2017. Average balances of securities decreased due to certain U. S. government agency securities and municipal securities being called and the normal monthly payments received related to the portfolio of mortgage-backed securities.
The Company's interest-earning deposits and non-interest-earning cash equivalents currently earn very low or no yield and therefore negatively impact the Company's net interest margin. At December 31, 2017, the Company had cash and cash equivalents of $242.3 million compared to $279.8 million at December 31, 2016. See "Net Interest Income" for additional information on the impact of this interest activity.
Total Interest Expense
Total interest expense increased $5.8 million, or 26.2%, during the year ended December 31, 2017, when compared with the year ended December 31, 2016, due to an increase in interest expense on deposits of $3.2 million, or 18.5%, an increase in interest expense on the subordinated notes issued during 2016 of $2.5 million, or 159.7%, an increase in interest expense on FHLBank advances of $302,000, or 24.9%, and an increase in interest expense on subordinated debentures issued to capital trust of $146,000, or 18.2%, partially offset by a decrease in interest expense on short-term and repurchase agreement borrowings of $390,000, or 34.3%.
Interest Expense - Deposits
Interest on demand deposits increased $653,000 due to an increase in average rates from 0.26% during the year ended December 31, 2016, to 0.30% during the year ended December 31, 2017. Interest on demand deposits increased $157,000 due to an increase in average balances from $1.50 billion in the year ended December 31, 2016, to $1.56 billion in the year ended December 31, 2017. The increase in average balances of interest-bearing demand deposits was primarily a result of increased balances in money market accounts. Market interest rates on these types of accounts have increased since December 2016.
Interest expense on time deposits increased $2.0 million as a result of an increase in average rates of interest from 0.98% during the year ended December 31, 2016, to 1.12% during the year ended December 31, 2017. Interest expense on time deposits increased $437,000 due to an increase in average balances of time deposits from $1.37 billion during the year ended December 31, 2016, to
84

$1.41 billion during the year ended December 31, 2017. The increase in average balances of time deposits was primarily a result of organic growth of retail deposits. A large portion of the Company's certificate of deposit portfolio matures within six to eighteen months and therefore reprices fairly quickly; this is consistent with the portfolio over the past several years. Older certificates of deposit that renewed or were replaced with new deposits generally had a higher rate of interest due to market interest rate increases since December 2016.
Interest Expense - FHLBank Advances, Short-term Borrowings and Structured Repurchase Agreements, Subordinated Debentures Issued to Capital Trust and Subordinated Notes
Interest expense on FHLBank advances increased due to higher average balances, partially offset by lower average rates of interest. Interest expense on FHLBank advances increased $416,000 due to an increase in average balances from $68.3 million during the year ended December 31, 2016, to $93.5 million during the year ended December 31, 2017. This increase was primarily due to the replacement of overnight borrowings with short-term three week FHLBank advances due to the short-term advances having a more favorable interest rate from time to time. The $31.5 million of the Company's long-term higher fixed-rate FHLBank advances were repaid during June 2017. Partially offsetting the increase due to higher average balances was a decrease in interest expense of $114,000 due to a decrease in average interest rates from 1.78% in the year ended December 31, 2016, to 1.62% in the year ended December 31, 2017. The decrease in the average rate was due to the repayment of the fixed-rate term FHLBank advances during June 2017 and the borrowing of shorter term FHLBank advances at a lower rate.
Interest expense on short-term borrowings and repurchase agreements decreased $546,000 due to a decrease in average balances from $327.7 million during the year ended December 31, 2016, to $186.4 million during the year ended December 31, 2017, which is primarily due to changes in the Company's funding needs and the mix of funding, which can fluctuate. The Company had a much higher amount of overnight borrowings from the FHLBank in 2016. Partially offsetting that decrease was an increase in interest expense on short-term borrowings and repurchase agreements of $156,000 due to average rates that increased from 0.35% in the year ended December 31, 2016, to 0.40% in the year ended December 31, 2017. The increase was due to increases in market interest rates and a change in the mix of funding during the period, with a lower percentage of the total made up of customer repurchase agreements, which have a lower interest rate.
During the year ended December 31, 2017, compared to the year ended December 31, 2016, interest expense on subordinated debentures issued to capital trusts increased $146,000 due to higher average interest rates. The average interest rate was 3.12% in 2016, compared to 3.68% in 2017. The amortization of the cost of interest rate caps the Company purchased in 2013 to limit the interest rate risk from rising LIBOR rates related to the Company's subordinated debentures issued to capital trusts effectively increased the rates for each year. The 2017 average interest rate was higher than 3.68% until the three months ended September 30, 2017, when the interest rate cap terminated based on its contractual terms, as a result of the amortization of the cost of the interest rate cap. There was no change in the average balance of the subordinated debentures between the 2017 and the 2016 years.
In August 2016, the Company issued $75 million of 5.25% fixed-to-floating rate subordinated notes due August 15, 2026. The notes were sold at par, resulting in net proceeds, after underwriting discounts and commissions and other issuance costs, of approximately $73.5 million. Interest expense on the subordinated notes for the year ended December 31, 2017, was $4.1 million, an increase of $2.5 million over the $1.6 million of interest expense for the year ended December 31, 2016. The increase was due to the fact that the notes were issued during the second half of 2016 and did not incur interest expense for the entire year in 2016.
Net Interest Income
Net interest income for the year ended December 31, 2017 decreased $7.9 million, to $155.2 million, compared to $163.1 million for the year ended December 31, 2016. Net interest margin was 3.74% for the year ended December 31, 2017, compared to 4.05% in 2016, a decrease of 31 basis points. In both years, the Company's net interest income and margin were significantly impacted by increases in expected cash flows to be received from the FDIC-acquired loan pools and the resulting increase to accretable yield, which was discussed previously in "Interest Income – Loans" and is discussed in Note 4 of the accompanying audited financial statements, which are included in Item 8 of this Report. The positive impact of these changes on the years ended December 31, 2017 and 2016 were increases in interest income of $5.0 million and $16.4 million, respectively, and increases in net interest margin of 12 basis points and 41 basis points, respectively. Excluding the positive impact of the additional yield accretion, net interest margin decreased 2 basis points during the year ended December 31, 2017. The decrease in net interest margin is primarily due to the interest expense associated with the issuance of $75.0 million of subordinated notes in August 2016 and an increase in the average interest rate on deposits and other borrowings.
The Company's overall interest rate spread decreased 34 basis points, or 8.6%, from 3.93% during the year ended December 31, 2016, to 3.59% during the year ended December 31, 2017. The decrease was due to an 18 basis point decrease in the weighted average yield on interest-earning assets and a 16 basis point increase in the weighted average rate paid on interest-bearing liabilities. In comparing the two years, the yield on loans decreased 26 basis points while the yield on investment securities and other interest-earning assets
85

increased 23 basis points. The rate paid on deposits increased 8 basis points, the rate paid on subordinated debentures issued to capital trust increased 56 basis points, the rate paid on short-term borrowings increased 5 basis points, the rate paid on subordinated notes increased 4 basis points and the rate paid on FHLBank advances decreased 16 basis points.

Provision for Loan Losses and Allowance for Loan Losses
Management records a provision for loan losses in an amount it believes sufficient to result in an allowance for loan losses that will cover current net charge-offs as well as risks believed to be inherent in the loan portfolio of the Bank. The amount of provision charged against current income is based on several factors, including, but not limited to, past loss experience, current portfolio mix, actual and potential losses identified in the loan portfolio, economic conditions, and internal as well as external reviews. The levels of non-performing assets, potential problem loans, loan loss provisions and net charge-offs fluctuate from period to period and are difficult to predict.
Weak economic conditions, higher inflation or interest rates, or other factors may lead to increased losses in the portfolio and/or requirements for an increase in loan loss provision expense. Management maintains various controls in an attempt to limit future losses, such as a watch list of possible problem loans, documented loan administration policies and a loan review staff to review the quality and anticipated collectability of the portfolio. Additional procedures provide for frequent management review of the loan portfolio based on loan size, loan type, delinquencies, financial analysis, on-going correspondence with borrowers and problem loan work-outs. Management determines which loans are potentially uncollectible, or represent a greater risk of loss, and makes additional provisions to expense, if necessary, to maintain the allowance at a satisfactory level.
The provision for loan losses for the year ended December 31, 2017 decreased $181,000, to $9.1 million, compared with $9.3 million for the year ended December 31, 2016. At December 31, 2017 and December 31, 2016, the allowance for loan losses was $36.5 million and $37.4 million, respectively. Total net charge-offs were $10.0 million and $10.0 million for the years ended December 31, 2017 and 2016, respectively. During the year ended December 31, 2017, $6.1 million of the $10.0 million of net charge-offs were in the consumer auto category. Five commercial loan relationships amounted to $2.9 million of the net charge-off total for the year ended December 31, 2017. In response to a more challenging consumer credit environment, the Company tightened its underwriting guidelines on automobile lending beginning in the latter part of 2016. Management took this step in an effort to improve credit quality in the portfolio and lower delinquencies and charge-offs. This action also resulted in a lower level of origination volume and, as such, the outstanding balance of the Company's automobile loans declined approximately $137 million in the year ended December 31, 2017. We expect to see further declines in the automobile loan totals through 2018 as well. General market conditions and unique circumstances related to individual borrowers and projects contributed to the level of provisions and charge-offs. As assets were categorized as potential problem loans, non-performing loans or foreclosed assets, evaluations were made of the values of these assets with corresponding charge-offs as appropriate.
In June 2017, the loss sharing agreements for Inter Savings Bank were terminated. In April 2016, the loss sharing agreements for Team Bank, Vantus Bank and Sun Security Bank were terminated. Loans acquired from the FDIC related to Valley Bank did not have a loss sharing agreement. All acquired loans were grouped into pools based on common characteristics and were recorded at their estimated fair values, which incorporated estimated credit losses at the acquisition date. These loan pools are systematically reviewed by the Company to determine the risk of losses that may exceed those identified at the time of the acquisition. Techniques used in determining risk of loss are similar to those used to determine the risk of loss for the legacy Great Southern Bank portfolio, with most focus being placed on those loan pools which include the larger loan relationships and those loan pools which exhibit higher risk characteristics. Review of the acquired loan portfolio also includes review of financial information, collateral valuations and customer interaction to determine if additional reserves are warranted.
The Bank's allowance for loan losses as a percentage of total loans, excluding acquired loans that were previously covered by the FDIC loss sharing agreements, was 1.01% and 1.04% at December 31, 2017 and December 31, 2016, respectively. Management considers the allowance for loan losses adequate to cover losses inherent in the Bank's loan portfolio at December 31, 2017, based on recent reviews of the Bank's loan portfolio and current economic conditions. If economic conditions were to deteriorate or management's assessment of the loan portfolio were to change, it is possible that additional loan loss provisions would be required, thereby adversely affecting future results of operations and financial condition.
Non-performing Assets
Former TeamBank, Vantus Bank, Sun Security Bank, InterBank and Valley Bank non-performing assets, including foreclosed assets and potential problem loans, are not included in the totals or in the discussion of non-performing loans, potential problem loans and foreclosed assets below. These assets were initially recorded at their estimated fair values as of their acquisition dates and are
86

accounted for in pools; therefore, these loan pools are analyzed rather than the individual loans. The performance of the loan pools acquired in the five transactions has been better than original expectations as of the acquisition dates.
As a result of changes in balances and composition of the loan portfolio, changes in economic and market conditions that occur from time to time, and other factors specific to a borrower's circumstances, the level of non-performing assets will fluctuate.
Non-performing assets, excluding all FDIC-assisted acquired assets, at December 31, 2017, were $27.8 million, a decrease of $11.5 million from $39.3 million at December 31, 2016. Non-performing assets, excluding all FDIC-assisted acquired assets, as a percentage of total assets were 0.63% at December 31, 2017, compared to 0.86% at December 31, 2016.
Compared to December 31, 2016, non-performing loans decreased $2.8 million to $11.3 million at December 31, 2017, and foreclosed assets decreased $8.7 million to $16.6 million at December 31, 2017. Non-performing consumer loans comprised $3.3 million, or 29.1%, of the total $11.3 million of non-performing loans at December 31, 2017. Non-performing one-to four-family residential loans comprised $2.7 million, or 24.2%, of the total non-performing loans at December 31, 2017. Non-performing commercial business loans were $2.1 million, or 18.3%, of total non-performing loans at December 31, 2017. The decrease in non-performing commercial business loans was primarily due to one relationship totaling $2.9 million which was transferred to foreclosed assets during 2017. Non-performing other residential loans were $1.9 million, or 16.7%, of total non-performing loans at December 31, 2017. The increase in non-performing other residential loans was primarily due to the additional of one loan initially totaling $2.4 million, which was charged down upon being added to Non-performing Loans. Non-performing commercial real estate loans comprised $1.2 million, or 10.9%, of total non-performing loans at December 31, 2017. The majority of the decrease in the commercial real estate category was due to one relationship incurring charge-offs of $1.2 million during 2017, and two separate relationship with transfers to foreclosed assets totaling approximately $500,000 each. Non-performing land development loans were $-0- at December 31, 2017. The decrease in non-performing land development loans was primarily due to the payoff of two significant relationships.
Non-performing Loans. Activity in the non-performing loans category during the year ended December 31, 2017, was as follows:

Commercial real estate collateral that secured one relationship, totaling $1.7 million, was either transferred to foreclosed assets or sold; therefore, the balance was reclassified from commercial real estate to commercial business in the Beginning Balance, January 1 presentation in the table above.
At December 31, 2017, the non-performing one- to four-family residential category included 28 loans, 18 of which were added during 2017. The largest relationship in this category, which was added during 2017, included nine loans totaling $1.4 million, or 50.6% of the total category, which are collateralized by residential rental homes in the Springfield, Mo. area. The non-performing commercial business category included five loans. The largest relationship in this category totaled $1.5 million, or 73.2% of the total category. This relationship, discussed in the paragraph above, was previously collateralized by commercial real estate which has been foreclosed and subsequently sold. Collection efforts are currently being pursued against the guarantors of the credit relationship. One loan in this category, totaling $2.9 million and secured by the borrower's interest in a condo project in Branson, Mo, was transferred to foreclosed assets during 2017. One loan totaling $970,000 was transferred from potential problem loans during 2017. This loan was added to potential problem loans earlier in 2017 and was subsequently transferred to non-performing loans. The loan was charged down $470,000 and the remaining balance at December 31, 2017 is $500,000. The loan is collateralized by the business assets of an entity in the St. Louis, Mo. area. The non-performing other residential category included one loan, which was added during 2017.

This loan is collateralized by an apartment project in the central Missouri area and was originated in 2004. The non-performing commercial real estate category included six loans, three of which were added during the year. The largest relationship in this category, which was added during 2017, totaled $667,000, or 54.4% of the total category. This loan is collateralized by commercial property in the St. Louis, Mo., area. One relationship in this category, which included two loans, had $358,000 of charge-offs during 2017 and the remaining balance of $465,000 was transferred to foreclosed assets. The relationship was collateralized by commercial entertainment property and other property in Branson, Mo. One loan in this category with a balance of $498,000 was transferred to foreclosed assets during the period. One relationship in this category, which was collateralized by a theatre property in Branson, Mo., incurred charge-offs of $1.2 million and received payments of $480,000 during the year, which paid off the remaining balance of that loan. The non-performing consumer category included 255 loans, 204 of which were added during the current year, and the majority of which are indirect used automobile loans. Compared to previous years, in 2016 and 2017 the Company has experienced increased levels of delinquencies and repossessions in consumer loans, primarily indirect used automobile loans. The non-performing land development category was zero at December 31, 2017. During the year, one loan, which is the same relationship as one of the loans discussed in the commercial real estate category, and was collateralized by land in the Branson, Mo. area had charge-offs of $92,000 and received payments of $3.8 million, which paid off the remaining balance of that loan. Also during 2017, one loan in this category received payments of $1.6 million, which paid off the remaining balance of that loan.
Foreclosed Assets. Of the total $22.0 million of other real estate owned at December 31, 2017, $2.1 million represents the fair value of foreclosed assets previously covered by FDIC loss sharing agreements, $1.7 million represents foreclosed assets related to Valley Bank and not previously covered by loss sharing agreements, and $1.6 million represents properties which were not acquired through foreclosure, including former branch locations that have been closed and are held for sale and land which was acquired for a potential branch location . The acquired foreclosed and other assets acquired in the FDIC-assisted transactions and the properties not acquired through foreclosure are not included in the following table and discussion of other real estate owned. Because sales of foreclosed properties exceeded additions, total foreclosed assets decreased. Activity in foreclosed assets during the year ended December 31, 2017, was as follows:

At December 31, 2017, the land development category of foreclosed assets included 17 properties, the largest of which was located in the Branson, Mo., area and had a balance of $1.2 million, or 17.2% of the total category. One property located in the northwest Arkansas area and totaling $1.4 million was sold during 2017. Of the total dollar amount in the land development category of foreclosed assets, 38.6% and 23.0% was located in the Branson, Mo. and the northwest Arkansas areas, respectively, including the largest property previously mentioned. The subdivision construction category of foreclosed assets included 15 properties, the largest of which was located in the Springfield, Mo. metropolitan area and had a balance of $1.2 million, or 22.8% of the total category. Of the total dollar amount in the subdivision construction category of foreclosed assets, 38.2% and 22.8% is located in Branson, Mo. and Springfield, Mo., respectively, including the largest property previously mentioned. The subdivision construction category of foreclosed assets had 16 properties with total or partial sales during 2017, totaling $1.3 million. The largest sale was a property in northwest Arkansas totaling $775,000. The commercial real estate category of foreclosed assets included four properties. The largest relationship in the commercial real estate category includes commercial properties in Springfield, Mo. and the surrounding area totaling $500,000, or 29.5% of the total category. The assets of one relationship in the commercial real estate category, which included one retail property located in Georgia and one retail property located in Texas totaling $1.5 million, were sold during 2017. One property in the commercial real estate category, which is a hotel located in the western United States totaling $1.1 million, was sold during the year. The commercial business category of other real estate has a balance of zero as of December 31, 2017, due to the sale of the one foreclosed property which was added to the category during the year totaling $2.9 million, which was collateralized by
88

the borrower's interest in a condominium project in Branson, Mo. The other residential category of foreclosed assets included one property which was added during 2017. All five properties which were held at the beginning of the year were sold, and included in those sales were four properties which were part of the same condominium community located in Branson, Mo. totaling $843,000. The larger amount of additions and sales under consumer loans are due to a higher volume of repossessions of automobiles, which generally are subject to a shorter repossession process. The Company experienced increased levels of delinquencies and repossessions in indirect used automobile loans throughout 2016 and 2017.
Potential Problem Loans. Potential problem loans increased $975,000 during the year ended December 31, 2017, from $7.0 million at December 31, 2016 to $7.9 million at December 31, 2017. This increase was due to the addition of $9.7 million of loans to potential problem loans, partially offset by $5.9 million in loans transferred to the non-performing category, $1.0 million in loans removed from potential problem loans due to improvements in the credits, $72,000 in charge-offs, $89,000 in loans transferred to foreclosed assets, and $1.7 million in payments on potential problem loans. Potential problem loans are loans which management has identified through routine internal review procedures as having possible credit problems that may cause the borrowers difficulty in complying with current repayment terms. These loans are not reflected in non-performing assets, but are considered in determining the adequacy of the allowance for loan losses. Activity in the potential problem loans category during the year ended December 31, 2017, was as follows:

|  | Beginning Balance, January 1 |  |  | Additions |  |  | Removed from Potential Problem |  |  | Transfers to Non- Performing |  |  | Transfers to Foreclosed Assets |  |  | Charge-Offs |  |  | Payments |  |  | Ending Balance, December 31 |

At December 31, 2017, the commercial real estate category of potential problem loans included three loans, all of which were part of the same customer relationship. This relationship, totaling $5.8 million, or 100.0% of the total category, is collateralized by theatre and retail property in Branson, Mo. This is a long-term customer of the Bank and these loans were all originated prior to 2008. The borrower is experiencing cash flow issues due to vacancies in some of the properties and the loans were added to potential problem loans during 2017. $963,000 of the payments in the category related to one relationship, the remainder of which was moved to non-performing loans during 2017. The one- to four-family residential category of potential problem loans included 16 loans, 10 of which were added during 2017. The commercial business category of potential problem loans included five loans, one of which was added during 2017. One loan in this category totaling $970,000 was added to potential problem loans during 2017 and then subsequently transferred to non-performing loans during the year, and is discussed above in non-performing loans. The consumer category of potential problem loans included 43 loans, 36 of which were added during 2017. The land development category of potential problem loans decreased from December 31, 2016 primarily due to the transfer of one loan totaling $3.8 million to the non-performing loans category, which is discussed above in non-performing loans.
Non-Interest Income
Non-interest income for the year ended December 31, 2017 was $38.5 million compared with $28.5 million for the year ended December 31, 2016. The increase of $10.0 million, or 35.1%, was primarily the result of the following items:
Gain on early termination of FDIC loss sharing agreement for Inter Savings Bank: As previously disclosed in the Company's Current Report on Form 8-K filed on June 9, 2017, the Company's loss sharing agreement with the FDIC related to Inter Savings Bank was terminated early and the Company received a payment of $15.0 million to settle all outstanding items related to the terminated agreement. The Company recognized a one-time gross gain in 2017 of $7.7 million related to the termination.
Amortization of income related to business acquisitions: Because of the termination of FDIC loss sharing agreements in previous periods, the net amortization expense related to business acquisitions was $486,000 for the year ended December 31, 2017, compared
89

to $6.4 million for the year ended December 31, 2016. The amortization expense for the year ended December 31, 2017, consisted of the following items: $504,000 of amortization expense related to the changes in cash flows expected to be collected from the FDIC-covered loan portfolios acquired from InterBank and $140,000 of amortization of the clawback liability. Partially offsetting the expense was income from the accretion of the discount related to the indemnification asset for the InterBank acquisition of $158,000.
Late charges and fees on loans: Late charges and fees on loans increased $484,000 compared to the prior year. The increase was primarily due to fees totaling $632,000 on loan payoffs received on four loan relationships during 2017.
Net gains on loan sales: Net gains on loan sales decreased $791,000 compared to the prior year. The decrease was due to a decrease in originations of fixed-rate loans in 2017 compared to 2016, which resulted in fewer loan sales during 2017. Fixed rate single-family loans originated are generally subsequently sold in the secondary market.
Other income: Other income decreased $825,000 compared to the prior year. During 2016, the Company recognized gains of $367,000 on the sale of the two branches in Southwest Missouri. In addition, a gain of $238,000 was recognized on sales of fixed assets unrelated to the branch sales during 2016. There were no similar transactions during 2017. There were net losses on the disposal of certain fixed assets, including ATMs, during the year ended December 31, 2017 of approximately $114,000, with no significant losses on the disposal of fixed assets in the comparable prior year.
Net realized gains on sales of available-for-sale securities: During 2016, the Company sold an investment held by Bancorp for a gain of $2.7 million and sold other investment securities for a net gain of $144,000. There were no gains on sales of investments in the current year.
Non-Interest Expense
Total non-interest expense decreased $6.1 million, or 5.1%, from $120.4 million in the year ended December 31, 2016, to $114.3 million in the year ended December 31, 2017. The Company's efficiency ratio for the year ended December 31, 2017 was 58.99%, a decrease from 62.86% in 2016. The improvement in the ratio for 2017 was primarily due to the decrease in non-interest expense and the increase in non-interest income (significantly impacted by the gain on the termination of the loss sharing agreements for the Inter Savings Bank FDIC-assisted transaction), partially offset by the decrease in net interest income. The Company's ratio of non-interest expense to average assets decreased from 2.76% for the year ended December 31, 2016, to 2.56% for the year ended December 31, 2017. The decrease in the current year ratio was due to the decrease in non-interest expense and the increase in average assets in 2017 compared to 2016. Average assets for the year ended December 31, 2017, increased $89.4 million, or 2.0%, from the year ended December 31, 2016, primarily due to organic loan growth, partially offset by decreases in investment securities.
The following were key items related to the decrease in non-interest expense for the year ended December 31, 2017 as compared to the year ended December 31, 2016:
Fifth Third Bank branch acquisition expenses: During 2016, the Company incurred approximately $1.4 million of one-time expenses related to the acquisition of certain branches from Fifth Third Bank. Those expenses included approximately $124,000 of compensation expense, approximately $385,000 of legal, audit and other professional fees expense, approximately $294,000 of computer license and support expense, approximately $436,000 in charges to replace former Fifth Third Bank customer checks with Great Southern Bank checks, and approximately $79,000 of travel, meals and other expenses related to the transaction.
Salaries and employee benefits: Salaries and employee benefits decreased $343,000 from the prior year. In 2016, the Company incurred one-time acquisition related net salary and retention bonus and other compensation expenses paid as part of the Fifth Third branch transaction totaling $124,000. Subsequent to the transaction, some employees related to those operations left the Company and many were not replaced. Compensation expense also decreased due to a reduction in incentive compensation for loan originators and staff due to fewer residential loan originations in 2017 than in 2016. The Company also recently reorganized some staff functions in certain areas to operate more efficiently. In addition, there are budgeted but unfilled positions in various areas of the Company that have resulted in lower compensation costs in these areas. These decreases were partially offset by the increase of $1.1 million related to the special employee bonuses paid to all employees who were employed by the Company on December 31, 2017. These bonuses were in response to the new federal tax reform legislation.
Net occupancy expense: Net occupancy expense decreased $1.5 million in the year ended December 31, 2017 compared to 2016. The decrease was primarily due to furniture, fixtures and equipment, and computer equipment which became fully depreciated during the past year resulting in less depreciation expense during the current year. During 2016, the Company had one-time expenses as part of the acquisition of the Fifth Third banking centers of $279,000 and increased computer license and support costs of $247,000 with no similar expenses in the current year.
90

Partnership tax credit: Partnership tax credit expense decreased $751,000 in the year ended December 31, 2017 compared to 2016. The decrease was primarily due to the end of the amortization period for some of the Company's new market tax credits and the investment in those tax credits has been written off.
Insurance expense: Insurance expense decreased $523,000 in the year ended December 31, 2017 compared to the prior year primarily due to a reduction in FDIC insurance premiums resulting from a change in the FDIC insurance assessment rates, which went into effect during the fourth quarter of 2016.
Postage: Postage decreased $330,000 from the prior year. During 2016, the Company incurred significant postage costs due to branch acquisitions and sales and the mailing of chip-enabled debit cards.
Legal, audit and other professional fees: Legal, audit and other professional fees decreased $329,000 from the prior year due to additional expenses in 2016 related to the Fifth Third transaction, as noted in the Fifth Third Bank branch acquisition expenses above.
Other operating expenses: Other operating expenses decreased $1.5 million in the year ended December 31, 2017 compared to the prior year. The decrease in other operating expenses was primarily due to higher levels of debit card and check fraud losses in the prior year. In 2016, the Company experienced debit card and check fraud losses totaling $1.9 million, a significant portion of which resulted from a data security breach at a national retail merchant which operates stores in many of our markets, affecting some of our debit card customers who transacted business with the merchant. In the 2017 period, the Company experienced debit card and check fraud losses totaling $1.0 million. Additionally, $436,000 of the decrease in operating expenses is the charge in 2016 to replace Fifth Third customer checks as discussed above.
Provision for Income Taxes
For the years ended December 31, 2017 and 2016, the Company's effective tax rate was 26.7% and 26.7%, respectively. These effective rates were lower than the statutory federal tax rate of 35%, due primarily to the utilization of certain investment tax credits and to tax-exempt investments and tax-exempt loans which reduced the Company's effective tax rate. The Company's effective tax rate may fluctuate as it is impacted by the level and timing of the Company's utilization of tax credits and the level of tax-exempt investments and loans and the overall level of pre-tax income. The Company's effective tax rate was higher than its typical effective tax rate in the 2016 and 2017 years due to increased net income resulting from the gain on termination of the loss sharing agreements for the Inter Savings Bank FDIC-assisted transaction (2017) and gains on the sales of investments (2016).
On December 22, 2017, the H.R.1, originally known as the "Tax Cuts and Jobs Act" (the "Act") was signed into law. Among other things, the Act permanently lowers the corporate federal income tax rate to 21% from the prior maximum rate of 35%, effective for tax years including or commencing January 1, 2018. As a result of the reduction of the corporate federal income tax rate to 21%, U.S. generally accepted accounting principles require companies to perform a revaluation of their deferred tax assets and liabilities as of the date of enactment, with the resulting tax effects accounted for in the reporting period of enactment (the year ended December 31, 2017). Deferred income taxes result from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in future years. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in years in which those temporary differences are expected to be recovered or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through income tax expense.
Based upon current accounting guidance and the utilization and recognition of the timing differences referred to above, the Company recorded a net decrease in income tax expense of approximately $250,000. This net decrease in income tax expense was comprised of a $2.1 million decrease from the adjustment of net deferred tax liabilities resulting from enactment of the Act, partially offset by the impacts of other tax planning strategies implemented. This impact on the Company's net deferred tax liabilities, which includes, among other things, the timing of recognition of various revenues and expenses, is based upon a review and analysis of the Company's net deferred tax liabilities at December 31, 2017, as well as expected adjustments to various deferred tax assets and deferred tax liabilities in the three months and year ended December 31, 2017, including those accounted for in accumulated other comprehensive income.
In addition, the Company currently expects its effective tax rate (combined federal and state) to decrease from approximately 26.7% in 2017 to approximately 15.5% to 17.5% in 2018, mainly as a result of the Act. The Company's effective income tax rate is expected to continue to be less than the statutory rate due primarily to investments in low-income housing tax credit projects and tax-exempt obligations. The Company's effective tax rate could change in future periods based on changes in the level of investments in tax credit projects and tax-exempt obligations, as well as changes in the level of overall pre-tax earnings.

Average Balances, Interest Rates and Yields
The following table presents, for the periods indicated, the total dollar amount of interest income from average interest-earning assets and the resulting yields, as well as the interest expense on average interest-bearing liabilities, expressed both in dollars and rates, and the net interest margin. Average balances of loans receivable include the average balances of non-accrual loans for each period. Interest income on loans includes interest received on non-accrual loans on a cash basis. Interest income on loans includes the amortization of net loan fees which were deferred in accordance with accounting standards. Fees included in interest income were $2.9 million, $5.0 million and $4.4 million for 2017, 2016 and 2015, respectively. Tax-exempt income was not calculated on a tax equivalent basis. The table does not reflect any effect of income taxes.

Rate/Volume Analysis
The following table presents the dollar amount of changes in interest income and interest expense for major components of interest-earning assets and interest-bearing liabilities for the periods shown. For each category of interest-earning assets and interest-bearing liabilities, information is provided on changes attributable to (i) changes in rate (i.e., changes in rate multiplied by old volume) and (ii) changes in volume (i.e., changes in volume multiplied by old rate). For purposes of this table, changes attributable to both rate and volume, which cannot be segregated, have been allocated proportionately to volume and rate. Tax-exempt income was not calculated on a tax equivalent basis.

Results of Operations and Comparison for the Years Ended December 31, 2016 and 2015
General
Net income decreased $1.2 million, or 2.5%, during the year ended December 31, 2016, compared to the year ended December 31, 2015. Net income was $45.3 million for the year ended December 31, 2016 compared to $46.5 million for the year ended December 31, 2015. This decrease was due to an increase in non-interest expense of $6.1 million, or 5.3%, a decrease in net interest income of $5.3 million, or 3.1%, an increase in the provision for loan losses of $3.8 million, or 68.2% and an increase in provision for income taxes of $952,000, or 6.1%, partially offset by an increase in non-interest income of $14.9 million, or 109.9%. Net income available to common shareholders was $45.3 million for the year ended December 31, 2016 compared to $45.9 million for the year ended December 31, 2015.
Total Interest Income
Total interest income increased $824,000, or 0.4%, during the year ended December 31, 2016 compared to the year ended December 31, 2015. The increase was due to a $1.6 million, or 0.9%, increase in interest income on loans, partially offset by an $819,000, or 11.5%, decrease in interest income on investment securities and other interest-earning assets. Interest income on loans increased in 2016 due to higher average balances on loans, partially offset by lower average rates of interest. Interest income from investment securities and other interest-earning assets decreased during 2016 compared to 2015 primarily due to lower average balances, partially offset by higher average rates of interest.

Interest Income - Loans
During the year ended December 31, 2016 compared to the year ended December 31, 2015, interest income on loans increased due to higher average balances, partially offset by lower average interest rates. Interest income increased $21.8 million as the result of higher average loan balances, which increased from $3.24 billion during the year ended December 31, 2015, to $3.66 billion during the year ended December 31, 2016. The higher average balances were primarily due to organic loan growth, in addition to the loans obtained as part of the Fifth Third Bank branch acquisition. Interest income decreased $20.2 million as the result of lower average interest rates on loans. The average yield on loans decreased from 5.48% during the year ended December 31, 2015 to 4.89% during the year ended December 31, 2016. This decrease was due to lower overall loan rates, and a lower amount of accretion income in the year ended December 31, 2016 resulting from the increases in expected cash flows to be received from the FDIC-acquired loan pools, which is discussed in Note 4 of the accompanying audited financial statements, included in Item 8 of this report.
On an on-going basis, the Company estimates the cash flows expected to be collected from the acquired loan pools. This cash flows estimate has increased, based on the payment histories and the collection of certain loans, thereby reducing loss expectations of certain loan pools, resulting in adjustments to be spread on a level-yield basis over the remaining expected lives of the loan pools. The loss sharing agreements for the Team Bank, Vantus Bank and Sun Security Bank transactions were terminated in April 2016, and the related indemnification assets were reduced to $-0- at that time. The Valley Bank transaction does not include a loss sharing agreement with the FDIC. Therefore, for these four acquisition transactions, there is no related indemnification asset. The entire amount of the discount adjustment has been and will be accreted to interest income over time with no offsetting impact to non-interest income. For the loan pools acquired in the InterBank transaction, the increases in expected cash flows also reduce the amount of expected reimbursements under the related loss sharing agreements with the FDIC, which were recorded as indemnification assets prior to the termination of the loss sharing agreements in 2017. Therefore, the expected indemnification asset also was reduced in 2016, resulting in adjustments that were to be amortized on a comparable basis until the loss sharing agreements were terminated or the remaining expected life of the loan pools, whichever was shorter. For the years ended December 31, 2016 and 2015, the adjustments increased interest income by $16.4 million and $28.5 million, respectively, and decreased non-interest income by $7.0 million and $19.5 million, respectively. The net impact to pre-tax income was $9.4 million and $9.0 million, respectively, for the years ended December 31, 2016 and 2015.
Apart from the yield accretion from the acquired loan pools, the average yield on loans was 4.44% during the year ended December 31, 2016, compared to 4.60% during the year ended December 31, 2015, as a result of loan pay-offs, normal amortization of higher-rate loans and new loans that were made at current lower market rates. Interest income also decreased due to significant interest recoveries in the prior year period, as discussed in the paragraph below.
In the year ended December 31, 2015, the Company collected $891,000 on certain acquired loans which had previously not been expected to be collectible. These collections were recorded as interest income in 2015 and had a positive impact on the net interest margin in that year of approximately three basis points. As the loans were subject to loss sharing agreements at that time, 80% of the amounts collected, or $713,000, was recorded in 2015 and included in non-interest income under "accretion (amortization) of income related to business acquisitions."
Interest Income - Investments and Other Interest-earning Assets
Interest income on investments and other interest-earning assets decreased $819,000 in the year ended December 31, 2016 compared to the year ended December 31, 2015. Interest income decreased $1.9 million as a result of a decrease in average balances from $483.0 million during the year ended December 31, 2015, to $366.3 million during the year ended December 31, 2016. Average balances of securities decreased due to certain U. S. government agency securities and municipal securities being called, the sale of certain mortgage-backed securities, normal monthly payments received related to the portfolio of mortgage-backed securities, and the sale during the year of an investment in a managed equity fund held by the Company. Interest income increased $1.1 million due to an increase in average interest rates from 1.47% during the year ended December 31, 2015 to 1.72% during the year ended December 31, 2016, due to a higher portion of the investment portfolio in tax-exempt municipal bonds and higher market rates of interest on other interest-bearing deposits in financial institutions.
The Company's interest-earning deposits and non-interest-earning cash equivalents currently earn very low or no yield and therefore negatively impact the Company's net interest margin. At December 31, 2016, the Company had cash and cash equivalents of $279.8 million compared to $199.2 million at December 31, 2015. See "Net Interest Income" for additional information on the impact of this interest activity.
Total Interest Expense
Total interest expense increased $6.1 million, or 38.3%, during the year ended December 31, 2016, when compared with the year ended December 31, 2015, due to an increase in interest expense on deposits of $3.9 million, or 28.7%, an increase in interest expense
95

on the subordinated notes issued in August 2016 of $1.6 million, an increase in interest expense on short-term and structured repo borrowings of $1.1 million, or 1,649.2%, and an increase in interest expense on subordinated debentures issued to capital trust of $89,000, or 12.5%, partially offset by a decrease in interest expense on FHLBank advances of $493,000, or 28.9%.
Interest Expense - Deposits
Interest on demand deposits increased $832,000 due to an increase in average rates from 0.20% during the year ended December 31, 2015, to 0.26% during the year ended December 31, 2016. Interest on demand deposits increased $198,000 due to an increase in average balances from $1.40 billion in the year ended December 31, 2015, to $1.50 billion in the year ended December 31, 2016. The increase in average balances of interest-bearing demand deposits was primarily a result of the deposits assumed as part of the Fifth Third Bank branch acquisition, partially offset by decreases in certain deposit types, such as public funds.
Interest expense on time deposits increased $1.8 million as a result of an increase in average rates of interest from 0.85% during the year ended December 31, 2015, to 0.98% during the year ended December 31, 2016. Interest expense on time deposits increased $1.0 million due to an increase in average balances of time deposits from $1.26 billion during the year ended December 31, 2015, to $1.37 billion during the year ended December 31, 2016. The increase in average balances of time deposits was primarily a result of increased balances of brokered deposits and time deposits opened through the Company's internet deposit acquisition channels
Interest Expense - FHLBank Advances, Short-term Borrowings and Structured Repurchase Agreements, Subordinated Debentures Issued to Capital Trust and Subordinated Notes
Interest expense on FHLBank advances decreased due to lower average balances, partially offset by higher average rates of interest. Interest expense on FHLBank advances decreased $1.4 million due to a decrease in average balances from $175.9 million during the year ended December 31, 2015, to $68.3 million during the year ended December 31, 2016. This decrease was primarily due to the paydown and partial replacement of short-term FHLBank advances with overnight fed funds borrowings from the FHLBank. Partially offsetting the decrease due to reduced average balances was an increase in interest expense of $919,000 due to an increase in average interest rates from 0.97% in the year ended December 31, 2015, to 1.78% in the year ended December 31, 2016. The increase in the average rate was due to a change in the mix of advances compared to the prior year. Short-term advances with very low interest rates were utilized more significantly in the prior year, which caused the overall average rate to be lower. In the current year, the Company utilized more overnight borrowings from the FHLBank which are included in short-term borrowings, with the remaining balance of FHLBank advances being longer term at a higher rate.
Interest expense on short-term borrowings and repurchase agreements increased $996,000 due to average rates that increased from 0.03% in the year ended December 31, 2015, to 0.35% in the year ended December 31, 2016. The increase was due to a change in the mix of borrowings in the current period, during which overnight fed funds borrowings from the FHLBank were increased, which are at a higher interest rate than customer repurchase agreements. Interest expense on short-term borrowings and repurchase agreements increased $76,000 due to an increase in average balances from $192.1 million during the year ended December 31, 2015, to $327.7 million during the year ended December 31, 2016, which is primarily due to an increase in short-term borrowings from the FHLBank.
During the year ended December 31, 2016, compared to the year ended December 31, 2015, interest expense on subordinated debentures issued to capital trusts increased $168,000 due to higher average interest rates. The average interest rate was 2.48% in 2015, compared to 3.12% in 2016. The increase in the interest rate resulted from the amortization of the cost of interest rate caps the Company purchased in 2013 to limit the interest rate risk from rising LIBOR rates related to the Company's subordinated debentures issued to capital trusts. Interest expense on subordinated debentures issued to capital trusts decreased $79,000 due to a decrease in average balances from $28.8 million for the year ended December 31, 2015 to $25.8 million during the year ended December 31, 2016. The average balance decreased because the Company redeemed $5.0 million of its subordinated debentures issued to capital trust during 2015. The remaining debentures are variable-rate debentures which bear interest at an average rate of three-month LIBOR plus 1.60%, adjusting quarterly.
In August 2016, the Company issued $75 million of 5.25% fixed-to-floating rate subordinated notes due August 15, 2026. The notes were sold at par, resulting in net proceeds, after underwriting discounts and commissions and other issuance costs, of approximately $73.5 million. Interest expense on the subordinated notes for the year ended December 31, 2016 was $1.6 million.
Net Interest Income
Net interest income for the year ended December 31, 2016 decreased $5.3 million to $163.1 million compared to $168.4 million for the year ended December 31, 2015. Net interest margin was 4.05% for the year ended December 31, 2016, compared to 4.53% in 2015, a decrease of 48 basis points. In both years, the Company's net interest income and margin were significantly impacted by the increases in expected cash flows to be received from the FDIC-acquired loan pools and the resulting increase to accretable yield, which was discussed previously in "Interest Income – Loans" and is discussed in Note 4 of the accompanying audited financial statements, which are included in Item 8 of this Report. The positive impact of these changes on the years ended December 31, 2016 and 2015 were increases in interest income of $16.4 million and $28.5 million, respectively, and increases in net interest margin of 41
96

basis points and 77 basis points, respectively. Excluding the positive impact of the additional yield accretion, net interest margin decreased 12 basis points during the year ended December 31, 2016. The decrease in net interest margin was primarily due to a decrease in average interest rate on loans (primarily due to decreased interest income on loans acquired in the FDIC-assisted transactions) and an increase in the average interest rate on time deposits and borrowings, partially offset by an increase in the average interest rate on investment securities.
The Company's overall interest rate spread decreased 51 basis points, or 11.5%, from 4.44% during the year ended December 31, 2015, to 3.93% during the year ended December 31, 2016. The decrease was due to a 36 basis point decrease in the weighted average yield on interest-earning assets and a 15 basis point increase in the weighted average rate paid on interest-bearing liabilities. In comparing the two years, the yield on loans decreased 59 basis points while the yield on investment securities and other interest-earning assets increased 25 basis points. The rate paid on deposits increased 10 basis points, the rate paid on FHLBank advances increased 81 basis points, the rate paid on short-term borrowings increased 32 basis points and the rate paid on subordinated debentures issued to capital trust increased 64 basis points. In addition, the subordinated notes issued in August 2016 paid interest at an average rate of 553 basis points.

Provision for Loan Losses and Allowance for Loan Losses
The provision for loan losses increased $3.8 million, to $9.3 million, during the year ended December 31, 2016, when compared with the year ended December 31, 2015. At December 31, 2016, the allowance for loan losses was $37.4 million, a decrease of $749,000 from December 31, 2015. Total net charge-offs were $10.0 million and $5.8 million for the years ended December 31, 2016 and 2015, respectively. Excluding those related to loans covered by loss sharing agreements, six relationships made up $5.5 million of the total $10.0 million in net charge-offs for the year ended December 31, 2016. Gross charge-offs for the year were partially offset by recoveries, including recoveries on two separate relationships totaling $1.1 million, which had previously been charged off. During the year ended December 31, 2016, $3.8 million of the $10.0 million of net charge-offs were in the consumer auto category. General market conditions and unique circumstances related to individual borrowers and projects contributed to the level of provisions and charge-offs. As properties were categorized as potential problem loans, non-performing loans or foreclosed assets, evaluations were made of the values of these assets with corresponding charge-offs as appropriate.
At December 31, 2016, loans acquired in the InterBank FDIC-assisted transaction were covered by loss sharing agreements between the FDIC and Great Southern Bank, which afforded Great Southern Bank at least 80% protection from losses in the acquired portfolio of loans. The FDIC loss sharing agreements were subject to limitations on the types of losses covered and the length of time losses were covered and was conditioned upon the Bank complying with its requirements in the agreements with the FDIC. These limitations are described in detail in Note 4 of the accompanying financial statements, which are included in Item 8 of this report. In April 2016, the loss sharing agreements for Team Bank, Vantus Bank and Sun Security Bank were terminated and in June 2017 the loss sharing agreements for InterBank were terminated. Loans acquired from the FDIC related to Valley Bank did not have a loss sharing agreement. All acquired loans were grouped into pools based on common characteristics and were recorded at their estimated fair values, which incorporated estimated credit losses at the acquisition date. These loan pools are systematically reviewed by the Company to determine the risk of losses that may exceed those identified at the time of the acquisition. Techniques used in determining risk of loss are similar to those used to determine the risk of loss for the legacy Great Southern Bank portfolio, with most focus being placed on those loan pools which include the larger loan relationships and those loan pools which exhibit higher risk characteristics. Review of the acquired loan portfolio also includes meetings with customers, review of financial information and collateral valuations to determine if any additional losses are apparent.
The allowance for loan losses as a percentage of total loans, excluding acquired covered and non-covered loans, was 1.04% and 1.20% at December 31, 2016 and 2015, respectively. Management considered the allowance for loan losses adequate to cover losses inherent in the Company's loan portfolio at December 31, 2016, based on recent reviews of the Company's loan portfolio and then-current economic conditions. If economic conditions were to deteriorate or management's assessment of the loan portfolio were to change, it is possible that additional loan loss provisions would be required, thereby adversely affecting future results of operations and financial condition.
Non-performing Assets
Former TeamBank, Vantus Bank, Sun Security Bank and InterBank non-performing assets, including foreclosed assets and potential problem loans, are not included in the totals or in the discussion of non-performing loans, potential problem loans and foreclosed assets below as they were subject to loss sharing agreements with the FDIC, which covered at least 80% of principal losses that could be incurred in these portfolios for the applicable terms under the agreements. In addition, these assets were initially recorded at their estimated fair values as of their acquisition dates. The overall performance of the loan pools acquired in 2009, 2011 and 2012 in
97

FDIC-assisted transactions has been better than original expectations as of the acquisition dates. Former Valley Bank loans are also excluded from the totals and the discussion of non-performing loans, potential problem loans and foreclosed assets below, although they are not covered by a loss sharing agreement. Former Valley Bank loans are accounted for in pools and were recorded at their fair value at the time of the acquisition; therefore, these loan pools are analyzed rather than the individual loans.
As previously discussed, the remaining loss sharing agreements for Team Bank, Vantus Bank and Sun Security Bank were terminated in April 2016 and the loss sharing agreements for InterBank were terminated in June 2017.
As a result of changes in balances and composition of the loan portfolio, changes in economic and market conditions that occur from time to time, and other factors specific to a borrower's circumstances, the level of non-performing assets will fluctuate.
Non-performing assets, excluding FDIC-covered and formerly covered non-performing assets and other FDIC-assisted acquired assets, at December 31, 2016, were $39.3 million, a decrease of $4.7 from $44.0 million at December 31, 2015. Non-performing assets, excluding FDIC-covered and formerly covered non-performing assets and other FDIC-assisted acquired assets, as a percentage of total assets were 0.86% at December 31, 2016, compared to 1.07% at December 31, 2015.
Compared to December 31, 2015, non-performing loans decreased $2.5 million to $14.1 million at December 31, 2016, and foreclosed assets decreased $2.1 million to $25.2 million at December 31, 2016. Non-performing commercial real estate loans comprised $4.4 million, or 31.3%, of the total of $14.1 million of non-performing loans at December 31, 2016. The majority of the decrease in the commercial real estate category was due to one relationship where the notes were sold and the loans paid off after charge-offs of $2.0 million during 2016. Another relationship totaling $982,000 was transferred to foreclosed assets. In addition, $3.1 million of the transfers to foreclosed assets in the commercial real estate category and approximately $670,000 of the charge-offs were related to another relationship. Non-performing commercial business loans were $3.1 million, or 21.9%, of total non-performing loans at December 31, 2016. The increase in non-performing commercial business loans was primarily due to the addition of one relationship in 2016. Non-performing consumer loans were $2.6 million, or 18.7%, of total non-performing loans at December 31, 2016. Non-performing one-to four-family residential loans comprised $2.0 million, or 13.9%, of the total non-performing loans at December 31, 2016. Non-performing land development loans were $1.7 million, or 12.2%, of total non-performing loans at December 31, 2016. The increase in non-performing land development loans was primarily due to the addition of one relationship in 2016.

At December 31, 2016, the non-performing commercial real estate category included 10 loans, seven of which were added during the year. The largest relationship in this category, which was added prior to 2016, totaled $1.7 million, or 38.5% of the total category, and is collateralized by a theatre property in Branson, Mo. One relationship in this category, which had a balance of $6.5 million at December 31, 2015, had $2.0 million in charge-offs and $5.1 million in payments (net of operating funds advanced) during the year. The relationship was collateralized by three operating long-term health care facilities in Missouri. These related notes were sold during 2016 for payment of the amount of the remaining balances after the charge-offs, resulting in a balance of zero at December 31, 2016. During 2016, $3.1 million of the transfers to foreclosed assets in the commercial real estate category and approximately $670,000 of the charge-offs were related to another relationship. This relationship is secured by property located in the Branson, Mo., area, and includes a lakefront resort, marina and related amenities, condominiums and lots. In addition to those relationships already discussed, $3.8 million of the transfers to foreclosed assets in the commercial real estate category during the year related to three additional relationships. The non-performing commercial business category included five loans, four of which were added during 2016. The largest loan in this category, which was added in 2016, totaled $3.0 million, or 95.6% of the total category, and is secured by the borrower's interest in a condo project in Branson, Mo. The Bank's lending involvement with this project dates back to 2005. This project had experienced some performance difficulties in the past and a new borrower became involved in this project during 2013. The non-performing one- to four-family residential category included 38 loans, 27 of which were added during 2016. The non-performing land development category included two loans. The largest loan in this category, which was originated in 2007, totaled $1.6 million, or 95.1% of the total category, and was collateralized by land in the St. Louis, Mo. area. The non-performing consumer category included 188 loans, 174 of which were added during 2016.
Foreclosed Assets. Of the total $32.7 million of other real estate owned at December 31, 2016, $1.4 million represents the fair value of foreclosed assets covered by FDIC loss sharing agreements, $316,000 represents the fair value of foreclosed assets previously covered by FDIC loss sharing agreements, $2.0 million represents foreclosed assets related to Valley Bank and not covered by loss sharing agreements, $9,000 represents other repossessed assets related to acquired loans, and $3.7 million represents properties which were not acquired through foreclosure, including former branch locations that have been closed and are held for sale and land which was acquired for a potential branch location . The acquired loss share covered and non-covered foreclosed and other assets acquired in the FDIC-assisted transactions and the properties not acquired through foreclosure are not included in the following table and discussion of other real estate owned. Because sales of foreclosed properties exceeded additions, total foreclosed assets decreased. Activity in foreclosed assets during the year ended December 31, 2016, was as follows:

At December 31, 2016, the land development category of foreclosed assets included 22 properties, the largest of which was located in northwest Arkansas and had a balance of $1.4 million, or 12.6% of the total category. Of the total dollar amount in the land development category of foreclosed assets, 39.1% and 33.1% was located in the Branson, Mo. area and in the northwest Arkansas area, respectively, including the largest property previously mentioned. The subdivision construction category of foreclosed assets included 27 properties, the largest of which was located in the Springfield, Mo. metropolitan area and had a balance of $1.2 million, or 19.4% of the total category. Of the total dollar amount in the subdivision construction category of foreclosed assets, 29.4% and 19.4% is located in Branson, Mo. and Springfield, Mo., respectively, including the largest property previously mentioned. The commercial real estate category of foreclosed assets included six properties. The largest relationship in the commercial real estate category, which includes two properties which were added during 2016, totaled $1.5 million, or 39.6% of the total category, and is made up of commercial retail property in Texas and Georgia, which was previously in non-performing loans. The second largest relationship in the commercial real estate category, which was added during 2016, totaled $1.3 million, or 33.3% of the total category, and is a hotel located in the western United States, which was previously in non-performing loans. The $6.2 million in sales in the commercial real estate category of foreclosed assets was primarily from three properties. Sales of $2.1 million related to a property which is located in southeast Missouri and was added in 2015. Sales of $2.9 million related to a property located in the Branson, Mo., area, and included a lakefront resort, marina and related amenities, condominiums and lots. Sales of $982,000 related to a motel property located in Springfield, Mo. The one-to four-family residential category of foreclosed assets included nine properties, of which the largest relationship, with one property in the southwest Missouri area, had a balance of $421,000, or 34.6% of the total category. Of the total dollar amount in the one-to- four-family category of foreclosed assets, 44.4% is located in the Branson, Mo., area. The other residential category of foreclosed assets included five properties, four of which were part of the same condominium community, located in Branson, Mo. and had a balance of $694,000, or 72.7% of the total category. The sales of $1.3 million in the other residential category were from six additional properties that were part of the same condominium community which were sold during 2016. The larger amount of additions and sales under consumer loans are due to a higher volume of repossessions of automobiles, which generally are subject to a shorter repossession process. Compared to previous years, in 2016 the Company experienced increased levels of delinquencies and repossessions in consumer loans, primarily indirect used automobile loans.
Potential Problem Loans. Potential problem loans decreased $5.8 million during the year ended December 31, 2016, from $12.8 million at December 31, 2015 to $7.0 million at December 31, 2016. This decrease was due to $6.0 million in loans transferred to the non-performing category, $2.6 million in loans removed from potential problem loans due to improvements in the credits, $2.2 million in charge-offs, $65,000 in loans transferred to foreclosed assets, and $3.4 million in payments on potential problem loans, partially offset by the addition of $8.5 million of loans to potential problem loans. Potential problem loans are loans which management has identified through routine internal review procedures as having possible credit problems that may cause the borrowers difficulty in complying with current repayment terms. These loans are not reflected in non-performing assets, but are considered in determining the adequacy of the allowance for loan losses. Activity in the potential problem loans category during the year ended December 31, 2016, was as follows:

At December 31, 2016, the land development category of potential problem loans included three loans. The largest loan in this category, which was added prior to 2016 and is collateralized by property in the Branson, Mo., area, totaled $3.8 million, or 92.9% of the total category. The commercial real estate category of potential problem loans included four loans, all of which were added prior to 2016. The largest relationship in this category contains two loans, with a total balance of $1.3 million, or 63.4% of the commercial real estate category. This relationship is collateralized by commercial entertainment property and other property in Branson, Mo. Two relationships made up $4.5 million in transfers to non-performing assets and $1.8 million in charge-offs in the commercial real estate category during 2016. These relationships are discussed above under non-performing loans. Of the $1.4 million in payments in this category, 95% was related to one loan, which was paid in full during 2016. The other residential category of potential problem loans has a balance of zero at December 31, 2016. During the year, payment was received in full on one loan which was previously included in the other residential category of potential problem loans totaling $2.0 million. This loan was to the same borrower that was referenced above in the land development category.
Non-Interest Income
Non-interest income for the year ended December 31, 2016 was $28.5 million compared with $13.6 million for the year ended December 31, 2015. The increase of $14.9 million, or 109.9 %, was primarily the result of the following items:
Amortization of income related to business acquisitions: The net amortization expense related to business acquisitions was reduced to $6.9 million for the year ended December 31, 2016, compared to $18.3 million for the year ended December 31, 2015. The amortization expense for the year ended December 31, 2016, consisted of the following items: $5.8 million of amortization expense related to the changes in cash flows expected to be collected from the FDIC-covered loan portfolios, $584,000 of impairment to certain indemnification assets and $1.4 million of amortization of the clawback liability. The impairment of the indemnification asset was recorded pursuant to the expected loss on the FDIC loss share termination agreements that occurred in April 2016, as discussed in the Company's March 31, 2016 Quarterly Report on Form 10-Q. Partially offsetting the expense was income from the accretion of the discount related to the indemnification asset for the InterBank acquisition of $896,000.
Net realized gains on sales of available-for-sale securities: During 2016, the Company sold an investment held at the holding company level for a gain of $2.7 million. This investment, the original amount of which was $1.0 million, was made in a managed equity fund. The Company was required to divest this investment as a result of recent regulations enacted by the Federal Reserve Board. There were no material gains on sales of investments in 2015.
Service charges and ATM fees: Service charges and ATM fees increased $1.8 million compared to the prior year, primarily due to the additional accounts acquired in the Fifth Third Bank transaction in January 2016, which have had high levels of debit card activity, and overall higher levels of point-of-sale card activity.
Other income: Other income decreased $918,000 compared to the prior year. During 2015, the Company recorded a $1.1 million gain when it redeemed the trust preferred securities previously issued by Great Southern Capital Trust III at a discount. Also in 2015, the Company sold a banking center building in Nebraska at a net gain of $671,000. In addition, during 2015, the Company recognized a $300,000 gain on the sale of a non-marketable investment. The Company recognized a $257,000 gain on the sale of the Thayer,
101

Mo., branch and deposits during the first quarter of 2016 and a $110,000 gain was recognized on the sale of the Buffalo, Mo., branch and deposits during the first quarter of 2016. In addition, in 2016, a gain of $238,000 was recognized on sales of fixed assets unrelated to the branch sales.
Non-Interest Expense
Total non-interest expense increased $6.0 million, or 5.3%, from $114.4 million in the year ended December 31, 2015, to $120.4 million in the year ended December 31, 2016. The Company's efficiency ratio for the year ended December 31, 2016 was 62.86%, slightly higher than the 62.85% in 2015. The 2016 ratio was negatively affected by the increase in non-interest expense and the decrease in net interest income, offset by an increase in non-interest income. The Company's ratio of non-interest expense to average assets decreased from 2.81% for the year ended December 31, 2015, to 2.76% for the year ended December 31, 2016. The decrease in the ratio for the year ended December 31, 2016 was due to the increase in average assets in 2016 compared to 2015, partially offset by the increase in non-interest expense. Average assets for the year ended December 31, 2016, increased $303.4 million, or 7.5%, from the year ended December 31, 2015. The following were key items related to the increase in non-interest expense for the year ended December 31, 2016 as compared to the year ended December 31, 2015:
Fifth Third Bank branch acquisition expenses: The Company incurred approximately $1.4 million of expenses during 2016 related to the acquisition of certain branches of Fifth Third Bank, versus approximately $482,000 in acquisition related expenses in the prior year. Those expenses for 2016 (net of prior year expense, if applicable), included approximately $317,000 of legal, audit and other professional fees expense, approximately $294,000 of computer license and support expense, approximately $436,000 in charges to replace former Fifth Third Bank customer checks with Great Southern Bank checks, and approximately $54,000 of travel, meals and other expenses related to the transaction and similar costs incurred during the year. A number of these increases are discussed in the related categories below.
Salaries and employee benefits: Salaries and employee benefits increased $1.7 million over the prior year period. Salaries increased due to additional employee costs related to the branches acquired from Fifth Third Bank during the first quarter of 2016 ($2.3 million during 2016), which was partially offset by the reduction in expenses related to the 16 banking centers which were closed or sold during the first quarter of 2016 ($1.7 million during the prior year). The remaining increase was due to increased staffing due to growth in lending and other operational areas.
Expense on foreclosed assets: Expense on foreclosed assets increased $1.6 million compared to the prior year due to expenses and valuation write-downs of foreclosed assets, and the loss on final disposition of certain assets during the current year. During 2016, expenses and loss on final disposition of two related properties totaling $320,000 were incurred. In addition, approximately $912,000 in valuation write-downs, primarily related to these two properties, were taken during 2016. Collection expenses and losses on sales of non-real estate assets (primarily automobiles) increased $652,000 in 2016 compared to 2015. The Company has increased its consumer lending, primarily in indirect automobile lending, significantly in the past few years though the Company's consumer loan portfolio decreased in 2017.
Other operating expenses: Other operating expenses increased $1.6 million in the year ended December 31, 2016 compared to 2015. Of this amount, $436,000 relates to check charges to replace Fifth Third customer checks as part of the acquisition in the first quarter of 2016. There was also increased expense due to higher levels of debit card and check fraud losses in 2016. These losses totaled $1.9 million in 2016 compared to $619,000 in 2015. A large portion of the increase related to debit card fraud that resulted from a data security breach at a national retail merchant which operates stores in many of our markets, affecting some of our debit card customers who transacted business with the merchant. The losses incurred by the Company resulted from regulatory requirements that banks reimburse debit card customers for unauthorized transactions.
Legal, audit and other professional fees: Legal, audit and other professional fees increased $478,000 from the prior year due to legal and professional fees related to the Fifth Third transaction, legal fees related to the resolution of two large non-performing loan relationships, and increased audit and accounting fees.
Supplies expense: Supplies expense increased $375,000 compared to the prior year primarily due to approximately $318,000 of one-time costs incurred to stock a supply of chip-enabled debit cards. In October 2016, the Company began mass issuing chip-enabled debit cards to its deposit customer base.
Provision for Income Taxes
The Company's effective tax rate was 26.7% and 25.1% for the years ended December 31, 2016 and 2015, respectively, which was lower than the statutory federal tax rate of 35%, due primarily to the utilization of certain investment tax credits and to tax-exempt investments and tax-exempt loans which reduced the Company's effective tax rate. In future periods, the Company expects its effective tax rate typically will be 26-28% of pre-tax net income, assuming it continues to maintain or increase its use of investment
102

tax credits and maintain or increase its pre-tax net income. The Company's effective tax rate may fluctuate as it is impacted by the level and timing of the Company's utilization of tax credits and the level of tax-exempt investments and loans and the overall level of pretax income.
Liquidity
Liquidity is a measure of the Company's ability to generate sufficient cash to meet present and future financial obligations in a timely manner through either the sale or maturity of existing assets or the acquisition of additional funds through liability management. These obligations include the credit needs of customers, funding deposit withdrawals and the day-to-day operations of the Company. Liquid assets include cash, interest-bearing deposits with financial institutions and certain investment securities and loans. As a result of the Company's management of the ability to generate liquidity primarily through liability funding, management believes that the Company maintains overall liquidity sufficient to satisfy its depositors' requirements and meet its customers' credit needs. At December 31, 2017, the Company had commitments of approximately $184.8 million to fund loan originations, $1.05 billion of unused lines of credit and unadvanced loans, and $20.0 million of outstanding letters of credit.
The following table summarizes the Company's fixed and determinable contractual obligations by payment date as of December 31, 2017. Additional information regarding these contractual obligations is discussed further in Notes 8, 9, 10, 11, 12, 13, 16 and 19 of the accompanying audited financial statements, which are included in Item 8 of this Report.

The Company's primary sources of funds are customer deposits, FHLBank advances, other borrowings, loan repayments, unpledged securities, proceeds from sales of loans and available-for-sale securities and funds provided from operations. The Company utilizes particular sources of funds based on the comparative costs and availability at the time. The Company has from time to time chosen not to pay rates on deposits as high as the rates paid by certain of its competitors and, when believed to be appropriate, supplements deposits with less expensive alternative sources of funds.
At December 31, 2017 and 2016, the Company had these available secured lines and on-balance sheet liquidity:

| December 31, 2017 |  | December 31, 2016
Federal Home Loan Bank line | $570.5 million |  | $551.0 million
Federal Reserve Bank line | 528.9 million |  | 602.0 million
Interest-Bearing and Non-Interest-Bearing Deposits | 242.3 million |  | 279.8 million
Unpledged Securities | 46.4 million |  | 50.7 million

Statements of Cash Flows. During the years ended December 31, 2017, 2016 and 2015, the Company had positive cash flows from operating activities. The Company experienced positive cash flows from investing activities during the year ended December 31, 2017 and negative cash flows from investing activities during the years ended December 31, 2016 and 2015. The Company experienced negative cash flows from financing activities during the year ended December 31, 2017 and positive cash flows from financing activities during the years ended December 31, 2016 and 2015.
Cash flows from operating activities for the periods covered by the Statements of Cash Flows have been primarily related to changes in accrued and deferred assets, credits and other liabilities, the provision for loan losses, realized gains on the sale of investment
103

securities and loans, depreciation and amortization, gains or losses on the termination of loss sharing agreements and the amortization of deferred loan origination fees and discounts (premiums) on loans and investments, all of which are non-cash or non-operating adjustments to operating cash flows. Net income adjusted for non-cash and non-operating items and the origination and sale of loans held-for-sale were the primary sources of cash flows from operating activities. Operating activities provided cash flows of $62.8 million, $80.6 million and $71.4 million during the years ended December 31, 2017, 2016 and 2015, respectively.
During the year ended December 31, 2017, investing activities provided cash of $81.4 million, primarily due to the cash received from the FDIC loss sharing termination reimbursement, proceeds from the sale of other real estate owned and the net repayment of investment securities. During the years ended December 31, 2016 and 2015, investing activities used cash of $198.7 million and $196.2 million, respectively, primarily due to the net increases and purchases of loans, partially offset by the net repayment or sales of investment securities.
Changes in cash flows from financing activities during the periods covered by the Statements of Cash Flows are primarily due to changes in deposits after interest credited, changes in FHLBank advances, changes in short-term borrowings, dividend payments to stockholders, issuance of subordinated notes (2016) and redemption of preferred stock (2015). Financing activities used cash flows of $181.7 million during the year ended December 31, 2017, primarily due to reduction of customer certificate of deposit balances, net increases or decreases in various borrowings and dividend payments to stockholders. Financing activities provided cash flows of $198.7 million and $105.3 million during the years ended December 31, 2016 and 2015, respectively, primarily due to increases in customer deposit balances, partially offset by net increases or decreases in various borrowings, dividend payments to stockholders, issuance of subordinated notes and redemption of preferred stock.
Capital Resources
Management continuously reviews the capital position of the Company and the Bank to ensure compliance with minimum regulatory requirements, as well as to explore ways to increase capital either by retained earnings or other means.
As of December 31, 2017, total stockholders' equity and common stockholders' equity were each $471.7 million, or 10.7% of total assets, equivalent to a book value of $33.48 per common share. As of December 31, 2016, total stockholders' equity and common stockholders' equity were each $429.8 million, or 9.4% of total assets, equivalent to a book value of $30.77 per common share. At December 31, 2017, the Company's tangible common equity to tangible assets ratio was 10.5% as compared to 9.2% at December 31, 2016.
Banks are required to maintain minimum risk-based capital ratios. These ratios compare capital, as defined by the risk-based regulations, to assets adjusted for their relative risk as defined by the regulations. Under current guidelines, which became effective January 1, 2015, banks must have a minimum common equity Tier 1 capital ratio of 4.50%, a minimum Tier 1 risk-based capital ratio of 6.00%, a minimum total risk-based capital ratio of 8.00%, and a minimum Tier 1 leverage ratio of 4.00%. To be considered "well capitalized," banks must have a minimum common equity Tier 1 capital ratio of 6.50%, a minimum Tier 1 risk-based capital ratio of 8.00%, a minimum total risk-based capital ratio of 10.00%, and a minimum Tier 1 leverage ratio of 5.00%. On December 31, 2017, the Bank's common equity Tier 1 capital ratio was 12.3%, its Tier 1 capital ratio was 12.3%, its total capital ratio was 13.2% and its Tier 1 leverage ratio was 11.7%. As a result, as of December 31, 2017, the Bank was well capitalized, with capital ratios in excess of those required to qualify as such. On December 31, 2016, the Bank's common equity Tier 1 capital ratio was 11.8%, its Tier 1 capital ratio was 11.8%, its total capital ratio was 12.7% and its Tier 1 leverage ratio was 10.8%. As a result, as of December 31, 2016, the Bank was well capitalized, with capital ratios in excess of those required to qualify as such.
The FRB has established capital regulations for bank holding companies that generally parallel the capital regulations for banks. On December 31, 2017, the Company's common equity Tier 1 capital ratio was 10.9%, its Tier 1 capital ratio was 11.4%, its total capital ratio was 14.1% and its Tier 1 leverage ratio was 10.9%. To be considered well capitalized, a bank holding company must have a Tier 1 risk-based capital ratio of at least 6.00% and a total risk-based capital ratio of at least 10.00%. As of December 31, 2017, the Company was considered well capitalized, with capital ratios in excess of those required to qualify as such. On December 31, 2016, the Company's common equity Tier 1 capital ratio was 10.2%, its Tier 1 capital ratio was 10.8%, its total capital ratio was 13.6% and its Tier 1 leverage ratio was 9.9%. As of December 31, 2016, the Company was considered well capitalized, with capital ratios in excess of those required to qualify as such.
In addition to the minimum common equity Tier 1 capital ratio, Tier 1 risk-based capital ratio and total risk-based capital ratio, the Company and the Bank have to maintain a capital conservation buffer consisting of additional common equity Tier 1 capital greater than 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends, repurchasing shares, and paying discretionary bonuses. This capital conservation buffer requirement began phasing in beginning on January 1, 2016 when a buffer greater than 0.625% of risk-weighted assets was required, which amount increased by an additional 0.625% as of January 1, 2017, and increases an equal amount each year until the buffer requirement of greater than 2.5% of risk-weighted assets is fully implemented on January 1, 2019.
104

On August 18, 2011, the Company entered into a Small Business Lending Fund-Securities Purchase Agreement ("Purchase Agreement") with the Secretary of the Treasury, pursuant to which the Company sold 57,943 shares of the Company's Senior Non-Cumulative Perpetual Preferred Stock, Series A (the "SBLF Preferred Stock") to the Secretary of the Treasury for a purchase price of $57.9 million. The SBLF Preferred Stock was issued pursuant to Treasury's SBLF program, a $30 billion fund established under the Small Business Jobs Act of 2010 that was created to encourage lending to small businesses by providing Tier 1 capital to qualified community banks and holding companies with assets of less than $10 billion. As required by the SBLF Purchase Agreement, the proceeds from the sale of the SBLF Preferred Stock were used in connection with the redemption of all 58,000 shares of the Company's preferred stock, issued to Treasury in December 2008 pursuant to Treasury's TARP Capital Purchase Program (the "CPP"). The shares of CPP Preferred Stock were redeemed at their liquidation amount of $1,000 per share plus the accrued but unpaid dividends to the redemption date.
The SBLF Preferred Stock qualified as Tier 1 capital. The holders of SBLF Preferred Stock were entitled to receive noncumulative dividends, payable quarterly, on each January 1, April 1, July 1 and October 1. The dividend rate, as a percentage of the liquidation amount, could fluctuate between one percent (1%) and five percent (5%) per annum on a quarterly basis during the first 10 quarters during which the SBLF Preferred Stock was outstanding, based upon changes in the level of "Qualified Small Business Lending" or "QSBL" (as defined in the SBLF Purchase Agreement) by the Bank over the adjusted baseline level calculated under the terms of the SBLF Preferred Stock $(249.7 million). Based upon the increase in the Bank's level of QSBL over the adjusted baseline level, the dividend rate had been 1.0%. For the tenth calendar quarter through four and one-half years after issuance, the dividend rate was fixed at one percent (1%) based upon the level of qualifying loans. After four and one half years from issuance, the dividend rate would have increased to 9% (including a quarterly lending incentive fee of 0.5%).
On December 15, 2015, the Company (with the approval of its federal banking regulator) redeemed all 57,943 shares of the SBLF Preferred Stock at their liquidation amount of $1,000 per share plus accrued but unpaid dividends to the redemption date. The redemption of the SBLF Preferred Stock was completed using internally available funds.
Dividends. During the year ended December 31, 2017, the Company declared common stock cash dividends of $0.94 per share (25.8% of net income per common share) and paid common stock cash dividends of $0.92 per share. During the year ended December 31, 2016, the Company declared common stock cash dividends of $0.88 per share (27.4% of net income per common share) and paid common stock cash dividends of $0.88 per share. The Board of Directors meets regularly to consider the level and the timing of dividend payments. The $0.24 per share dividend declared but unpaid as of December 31, 2017, was paid to stockholders in January 2018. In addition, the Company paid preferred dividends as described below in years prior to 2016.
While the SBLF Preferred Stock was outstanding, the terms of the SBLF Preferred Stock limited the ability of the Company to pay dividends and repurchase shares of common stock. Under the terms of the SBLF Preferred Stock, no repurchases could be effected, and no dividends could be declared or paid on preferred shares ranking pari passu with the SBLF Preferred Stock, junior preferred shares, or other junior securities (including the common stock) during the current quarter and for the next three quarters following the failure to declare and pay dividends on the SBLF Preferred Stock, except that, in any such quarter in which the dividend is paid, dividend payments on shares ranking pari passu may be paid to the extent necessary to avoid any resulting material covenant breach.
Under the terms of the SBLF Preferred Stock, the Company could only declare and pay a dividend on the common stock or other stock junior to the SBLF Preferred Stock, or repurchase shares of any such class or series of stock, if, after payment of such dividend, or after giving effect to such repurchase, (i) the dollar amount of the Company's Tier 1 Capital would be at least equal to the "Tier 1 Dividend Threshold" and (ii) full dividends on all outstanding shares of SBLF Preferred Stock for the most recently completed dividend period have been or are contemporaneously declared and paid. We satisfied this condition through the redemption date of the SBLF Preferred Stock.
Common Stock Repurchases and Issuances. The Company has been in various buy-back programs since May 1990. Our ability to repurchase common stock was limited, but allowed, under the terms of the SBLF Preferred Stock as noted above, under "-Dividends" and was previously generally precluded due to our participation in the CPP from December 2008 through August 2011. During the years ended December 31, 2017 and 2016, the Company did not repurchase any shares of its common stock. During the years ended December 31, 2017 and 2016, the Company issued 119,147 shares of stock at an average price of $27.35 per share and 80,454 shares of stock at an average price of $26.47 per share, respectively, to cover stock option exercises.
Management has historically utilized stock buy-back programs from time to time as long as management believed that repurchasing the stock would contribute to the overall growth of shareholder value. The number of shares of stock that will be repurchased at any particular time and the prices that will be paid are subject to many factors, several of which are outside of the control of the Company. The primary factors, however, are the number of shares available in the market from sellers at any given time, the price of the stock within the market as determined by the market and the projected impact on the Company's earnings per share and capital.

Non-GAAP Financial Measures
This document contains certain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States ("GAAP"). These non-GAAP financial measures include tangible common equity to tangible assets ratio.
In calculating the ratio of tangible common equity to tangible assets, we subtract period-end intangible assets from common equity and from total assets. Management believes that the presentation of these measures excluding the impact of intangible assets provides useful supplemental information that is helpful in understanding our financial condition and results of operations, as they provide a method to assess management's success in utilizing our tangible capital as well as our capital strength. Management also believes that providing measures that exclude balances of intangible assets, which are subjective components of valuation, facilitates the comparison of our performance with the performance of our peers. In addition, management believes that these are standard financial measures used in the banking industry to evaluate performance.
These non-GAAP financial measures are supplemental and are not a substitute for any analysis based on GAAP financial measures. Because not all companies use the same calculation of non-GAAP measures, this presentation may not be comparable to other similarly titled measures as calculated by other companies.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Asset and Liability Management and Market Risk
A principal operating objective of the Company is to produce stable earnings by achieving a favorable interest rate spread that can be sustained during fluctuations in prevailing interest rates. The Company has sought to reduce its exposure to adverse changes in interest rates by attempting to achieve a closer match between the periods in which its interest-bearing liabilities and interest-earning assets can be expected to reprice through the origination of adjustable-rate mortgages and loans with shorter terms to maturity and the purchase of other shorter term interest-earning assets.
Our Risk When Interest Rates Change
The rates of interest we earn on assets and pay on liabilities generally are established contractually for a period of time. Market interest rates change over time. Accordingly, our results of operations, like those of other financial institutions, are impacted by changes in interest rates and the interest rate sensitivity of our assets and liabilities. The risk associated with changes in interest rates and our ability to adapt to these changes is known as interest rate risk and is our most significant market risk.
How We Measure the Risk to Us Associated with Interest Rate Changes
In an attempt to manage our exposure to changes in interest rates and comply with applicable regulations, we monitor Great Southern's interest rate risk. In monitoring interest rate risk we regularly analyze and manage assets and liabilities based on their payment streams and interest rates, the timing of their maturities and their sensitivity to actual or potential changes in market interest rates.
The ability to maximize net interest income is largely dependent upon the achievement of a positive interest rate spread that can be sustained despite fluctuations in prevailing interest rates. Interest rate sensitivity is a measure of the difference between amounts of interest-earning assets and interest-bearing liabilities which either reprice or mature within a given period of time. The difference, or the interest rate repricing "gap," provides an indication of the extent to which an institution's interest rate spread will be affected by changes in interest rates. A gap is considered positive when the amount of interest-rate sensitive assets exceeds the amount of interest-rate sensitive liabilities repricing during the same period, and is considered negative when the amount of interest-rate sensitive liabilities exceeds the amount of interest-rate sensitive assets during the same period. Generally, during a period of rising interest rates, a negative gap within shorter repricing periods would adversely affect net interest income, while a positive gap within shorter repricing periods would result in an increase in net interest income. During a period of falling interest rates, the opposite would be true. As of December 31, 2017, Great Southern's interest rate risk models indicate that, generally, rising interest rates are expected to have a positive impact on the Company's net interest income, while declining interest rates would have a negative impact on net interest income. We model various interest rate scenarios for rising and falling rates, including both parallel and non-parallel shifts in rates. The results of our modeling indicate that net interest income is not likely to be materially affected either positively or negatively in the first twelve months following a rate change, regardless of any changes in interest rates, because our portfolios are relatively well matched in a twelve-month horizon. The effects of interest rate changes, if any, are expected to be more impacting to net interest income in the 12 to 36 months following a rate change.
The current level and shape of the interest rate yield curve poses challenges for interest rate risk management. Prior to its increase of 0.25% on December 16, 2015, the Federal Reserve Board had last changed interest rates on December 16, 2008. This was the first rate increase since September 29, 2006. The FRB has now also implemented rate increases of 0.25% on December 14, 2016, March 15, 2017, June 14, 2017 and December 13, 2017. A substantial portion of Great Southern's loan portfolio ($1.31 billion at December 31, 2017) is tied to the one-month or three-month LIBOR index and will adjust at least once within 90 days after December 31, 2017. Of these loans, $934 million as of December 31, 2017 had interest rate floors. Great Southern also has a significant portfolio of loans ($318 million at December 31, 2017) which are tied to a "prime rate" of interest and will adjust immediately with changes to the "prime rate" of interest.
Interest rate risk exposure estimates (the sensitivity gap) are not exact measures of an institution's actual interest rate risk. They are only indicators of interest rate risk exposure produced in a simplified modeling environment designed to allow management to gauge the Bank's sensitivity to changes in interest rates. They do not necessarily indicate the impact of general interest rate movements on the Bank's net interest income because the repricing of certain categories of assets and liabilities is subject to competitive and other factors beyond the Bank's control. As a result, certain assets and liabilities indicated as maturing or otherwise repricing within a stated period may in fact mature or reprice at different times and in different amounts and cause a change, which potentially could be material, in the Bank's interest rate risk.
In order to minimize the potential for adverse effects of material and prolonged increases and decreases in interest rates on Great Southern's results of operations, Great Southern has adopted asset and liability management policies to better match the maturities and repricing terms of Great Southern's interest-earning assets and interest-bearing liabilities. Management recommends and the Board
107

of Directors sets the asset and liability policies of Great Southern which are implemented by the Asset and Liability Committee. The Asset and Liability Committee is chaired by the Chief Financial Officer and is comprised of members of Great Southern's senior management. The purpose of the Asset and Liability Committee is to communicate, coordinate and control asset/liability management consistent with Great Southern's business plan and board-approved policies. The Asset and Liability Committee establishes and monitors the volume and mix of assets and funding sources taking into account relative costs and spreads, interest rate sensitivity and liquidity needs. The objectives are to manage assets and funding sources to produce results that are consistent with liquidity, capital adequacy, growth, risk and profitability goals. The Asset and Liability Committee meets on a monthly basis to review, among other things, economic conditions and interest rate outlook, current and projected liquidity needs and capital positions and anticipated changes in the volume and mix of assets and liabilities. At each meeting, the Asset and Liability Committee recommends appropriate strategy changes based on this review. The Chief Financial Officer or his designee is responsible for reviewing and reporting on the effects of the policy implementations and strategies to the Board of Directors at their monthly meetings.
In order to manage its assets and liabilities and achieve the desired liquidity, credit quality, interest rate risk, profitability and capital targets, Great Southern has focused its strategies on originating adjustable rate loans or loans with fixed rates that mature in less than five years, and managing its deposits and borrowings to establish stable relationships with both retail customers and wholesale funding sources.
At times, depending on the level of general interest rates, the relationship between long- and short-term interest rates, market conditions and competitive factors, we may determine to increase our interest rate risk position somewhat in order to maintain or increase our net interest margin.
The Asset and Liability Committee regularly reviews interest rate risk by forecasting the impact of alternative interest rate environments on net interest income and market value of portfolio equity, which is defined as the net present value of an institution's existing assets, liabilities and off-balance sheet instruments, and evaluating such impacts against the maximum potential changes in net interest income and market value of portfolio equity that are authorized by the Board of Directors of Great Southern.
In the normal course of business, the Company may use derivative financial instruments (primarily interest rate swaps) from time to time to assist in its interest rate risk management. In 2011, the Company began executing interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. Because the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. These interest rate derivatives result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in the Company's assets or liabilities. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions.
In 2013, the Company entered into two interest rate cap agreements related to its floating rate debt associated with its trust preferred securities. The agreements provide that the counterparty will reimburse the Company if interest rates rise above a certain threshold, thus creating a cap on the effective interest rate paid by the Company. These agreements are classified as hedging instruments, and the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. During 2015, the Company redeemed $5.0 million of the total $30.0 million of its trust preferred securities. The interest rate cap related to this $5.0 million trust preferred security was terminated and the remaining cost of this interest rate cap was amortized to interest expense in 2015. The interest rate cap related to the $25.0 million trust preferred security terminated per its contractual terms in the third quarter of 2017.
The Company's interest rate derivatives and hedging activities are discussed further in Note 17 of the accompanying audited financial statements, which are included in Item 8 of this Report.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the Company's internal control over financial reporting as of December 31, 2017, based on Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and our report dated March 6, 2018, expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits.
We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Note 1: | Nature of Operations and Summary of Significant Accounting Policies

Nature of Operations and Operating Segments
Great Southern Bancorp, Inc. ("GSBC" or the "Company") operates as a one-bank holding company. GSBC's business primarily consists of the operations of Great Southern Bank (the "Bank"), which provides a full range of financial services to customers primarily located in Missouri, Iowa, Kansas, Minnesota, Nebraska and Arkansas. The Bank also originates commercial loans from lending offices in Dallas, Texas, Tulsa, Oklahoma and Chicago, Illinois. The Company and the Bank are subject to regulation by certain federal and state agencies and undergo periodic examinations by those regulatory agencies.
The Company's banking operation is its only reportable segment. The banking operation is principally engaged in the business of originating residential and commercial real estate loans, construction loans, commercial business loans and consumer loans and funding these loans by attracting deposits from the general public, accepting brokered deposits and borrowing from the Federal Home Loan Bank and others. The operating results of this segment are regularly reviewed by management to make decisions about resource allocations and to assess performance. Selected information is not presented separately for the Company's reportable segment, as there is no material difference between that information and the corresponding information in the consolidated financial statements.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, the valuation of loans acquired with indication of impairment, the valuation of the FDIC indemnification asset (prior to December 31, 2017) and other-than-temporary impairments (OTTI) and fair values of financial instruments. In connection with the determination of the allowance for loan losses and the valuation of foreclosed assets held for sale, management obtains independent appraisals for significant properties. The valuation of the FDIC indemnification asset was determined in relation to the fair value of assets acquired through FDIC-assisted transactions for which cash flows are monitored on an ongoing basis. In addition, the Company considers that the determination of the carrying value of goodwill and intangible assets involves a high degree of judgment and complexity.
Principles of Consolidation
The consolidated financial statements include the accounts of Great Southern Bancorp, Inc., its wholly owned subsidiary, the Bank, and the Bank's wholly owned subsidiaries, Great Southern Real Estate Development Corporation, GSB One LLC (including its wholly owned subsidiary, GSB Two LLC), Great Southern Financial Corporation, Great Southern Community Development Company, LLC (including its wholly owned subsidiary, Great Southern CDE, LLC), GS, LLC, GSSC, LLC, GSTC Investments, LLC, GS-RE Holding, LLC (including its wholly owned subsidiary, GS RE Management,

LLC), GS-RE Holding II, LLC, GS-RE Holding III, LLC, VFP Conclusion Holding, LLC and VFP Conclusion Holding II, LLC. All significant intercompany accounts and transactions have been eliminated in consolidation.
Reclassifications
Certain prior periods' amounts have been reclassified to conform to the 2017 financial statements presentation. These reclassifications had no effect on net income.
Federal Home Loan Bank Stock
Federal Home Loan Bank common stock is a required investment for institutions that are members of the Federal Home Loan Bank system. The required investment in common stock is based on a predetermined formula, carried at cost and evaluated for impairment.
Securities
Available-for-sale securities, which include any security for which the Company has no immediate plan to sell but which may be sold in the future, are carried at fair value. Unrealized gains and losses are recorded, net of related income tax effects, in other comprehensive income.
Held-to-maturity securities, which include any security for which the Company has the positive intent and ability to hold until maturity, are carried at historical cost adjusted for amortization of premiums and accretion of discounts.
Amortization of premiums and accretion of discounts are recorded as interest income from securities. Realized gains and losses are recorded as net security gains (losses). Gains and losses on sales of securities are determined on the specific-identification method.
For debt securities with fair value below carrying value when the Company does not intend to sell a debt security, and it is more likely than not the Company will not have to sell the security before recovery of its cost basis, it recognizes the credit component of an other-than-temporary impairment ("OTTI") of a debt security in earnings and the remaining portion in other comprehensive income. For held-to-maturity debt securities, the amount of an OTTI recorded in other comprehensive income for the noncredit portion of a previous OTTI is amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security.
The Company's consolidated statements of income reflect the full impairment (that is, the difference between the security's amortized cost basis and fair value) on debt securities that the Company intends to sell or would more likely than not be required to sell before the expected recovery of the amortized cost basis. For available-for-sale and held-to-maturity debt securities that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security based on cash flow projections.
For equity securities, if any, when the Company has decided to sell an impaired available-for-sale security and the Company does not expect the fair value of the security to fully recover before the expected time of sale, the security is deemed OTTI in the period in which the decision to sell is made. The Company recognizes an impairment loss when the impairment is deemed other-than-temporary even if a decision to sell has not been made.

Mortgage Loans Held for Sale
Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value in the aggregate. Write-downs to fair value are recognized as a charge to earnings at the time the decline in value occurs. Nonbinding forward commitments to sell individual mortgage loans are generally obtained to reduce market risk on mortgage loans in the process of origination and mortgage loans held for sale. Gains and losses resulting from sales of mortgage loans are recognized when the respective loans are sold to investors. Fees received from borrowers to guarantee the funding of mortgage loans held for sale and fees paid to investors to ensure the ultimate sale of such mortgage loans are recognized as income or expense when the loans are sold or when it becomes evident that the commitment will not be used.
Loans Originated by the Company
Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balances adjusted for any charge-offs, the allowance for loan losses, any deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. Interest income is reported on the interest method and includes amortization of net deferred loan fees and costs over the loan term. Past due status is based on the contractual terms of a loan. Generally, loans are placed on nonaccrual status at 90 days past due and interest is considered a loss, unless the loan is well secured and in the process of collection. Payments received on nonaccrual loans are applied to principal until the loans are returned to accrual status. Loans are returned to accrual status when all payments contractually due are brought current, payment performance is sustained for a period of time, generally six months, and future payments are reasonably assured. With the exception of consumer loans, charge-offs on loans are recorded when available information indicates a loan is not fully collectible and the loss is reasonably quantifiable. Consumer loans are charged-off at specified delinquency dates consistent with regulatory guidelines.
Allowance for Loan Losses
The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance.
The allowance for loan losses is evaluated on a regular basis by management and is based upon management's periodic review of the collectibility of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.
The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For loans classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical charge-off experience and expected loss given default derived from the Company's internal risk rating process. Other adjustments may be made to the allowance for certain loan segments after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data.

December 31, 2017, 2016 and 2015
A loan is considered impaired when, based on current information and events, it is probable that not all of the principal and interest due under the loan agreement will be collected in accordance with contractual terms. For non-homogeneous loans, such as commercial loans, management determines which loans are reviewed for impairment based on information obtained by account officers, weekly past due meetings, various analyses including annual reviews of large loan relationships, calculations of loan debt coverage ratios as financial information is obtained and periodic reviews of all loans over $1.0 million. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length and reasons for the delay, the borrower's prior payment record and the amount of any collateral shortfall in relation to the principal and interest owed.
Large groups of smaller balance homogenous loans, such as consumer and residential loans, are collectively evaluated for impairment. In accordance with regulatory guidelines, impairment in the consumer and mortgage loan portfolio is primarily identified based on past-due status. Consumer and mortgage loans which are over 90 days past due or specifically identified as troubled debt restructurings will generally be individually evaluated for impairment.
Impairment is measured on a loan-by-loan basis for both homogeneous and non-homogeneous loans by either the present value of expected future cash flows or the fair value of the collateral if the loan is collateral dependent. Payments made on impaired loans are treated in accordance with the accrual status of the loan. If loans are performing in accordance with their contractual terms but the ultimate collectability of principal and interest is questionable, payments are applied to principal only.
Loans Acquired in Business Combinations
Loans acquired in business combinations under ASC Topic 805, Business Combinations, require the use of the purchase method of accounting. Therefore, such loans are initially recorded at fair value in accordance with the fair value methodology prescribed in ASC Topic 820, Fair Value Measurements and Disclosures. No allowance for loan losses related to the acquired loans is recorded on the acquisition date as the fair value of the loans acquired incorporates assumptions regarding credit risk. The fair value estimates associated with the loans include estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows.
For loans not acquired in conjunction with an FDIC-assisted transaction that are not considered to be purchased credit-impaired loans, the Company evaluates those loans acquired in accordance with the provisions of ASC Topic 310-20, Nonrefundable Fees and Other Costs. The fair value discount on these loans is accreted into interest income over the weighted average life of the loans using a constant yield method. These loans are not considered to be impaired loans. The Company evaluates purchased credit-impaired loans in accordance with the provisions of ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. Loans acquired in business combinations with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit impaired. Evidence of credit quality deterioration as of the purchase dates may include information such as past-due and nonaccrual status, borrower credit scores and recent loan to value percentages. Acquired credit-impaired loans that are accounted for under the accounting guidance for loans acquired with deteriorated credit quality are initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loans.

Notes to Consolidated Financial Statements
December 31, 2017, 2016 and 2015
The Company evaluates all of its loans acquired in conjunction with its FDIC-assisted transactions in accordance with the provisions of ASC Topic 310-30. For purposes of applying ASC 310-30, loans acquired in FDIC-assisted business combinations are aggregated into pools of loans with common risk characteristics. All loans acquired in the FDIC transactions, both covered and not covered by loss sharing agreements, were deemed to be purchased credit-impaired loans as there is general evidence of credit deterioration since origination in the pools and there is some probability that not all contractually required payments will be collected. As a result, related discounts are recognized subsequently through accretion based on changes in the expected cash flows of these acquired loans.
The expected cash flows of the acquired loan pools in excess of the fair values recorded is referred to as the accretable yield and is recognized in interest income over the remaining estimated lives of the loan pools for impaired loans accounted for under ASC Topic 310-30. The Company continues to estimate cash flows expected to be collected on pools of loans sharing common risk characteristics, which are treated in the aggregate when applying various valuation techniques. Increases in the Company's cash flow expectations are recognized as increases to the accretable yield while decreases are recognized as impairments through the allowance for loan losses.
FDIC Indemnification Asset
Through two FDIC-assisted transactions during 2009, one during 2011 and one during 2012, the Bank acquired certain loans and foreclosed assets which were covered under loss sharing agreements with the FDIC. These agreements committed the FDIC to reimburse the Bank for a portion of realized losses on these covered assets. Therefore, as of the dates of acquisitions, the Company calculated the amount of such reimbursements it expected to receive from the FDIC using the present value of anticipated cash flows from the covered assets based on the credit adjustments estimated for each pool of loans and the estimated losses on foreclosed assets. In accordance with FASB ASC 805, each FDIC Indemnification Asset was initially recorded at its fair value, and was measured separately from the loan assets and foreclosed assets because the loss sharing agreements were not contractually embedded in them or transferrable with them in the event of disposal. The balance of the FDIC Indemnification Asset increased and decreased as the expected and actual cash flows from the covered assets fluctuated, as loans were paid off or impaired and as loans and foreclosed assets were sold. There were no contractual interest rates on the contractual receivables from the FDIC; however, a discount was recorded against the initial balance of the FDIC Indemnification Asset in conjunction with the fair value measurement as the receivable was to be collected over the terms of the loss sharing agreements. This discount was accreted to income up until the termination of the loss sharing agreements. During 2016 and 2017, the Company and the FDIC mutually agreed to terminate all of these loss sharing agreements prior to their contractual termination dates. These acquisitions and agreements are more fully discussed in Note 4.
Other Real Estate Owned and Repossessions
Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less estimated cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less estimated cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net expense on foreclosed assets. Other real estate owned also includes bank premises formerly, but no longer, used for banking, as well as property originally acquired for future expansion but no longer intended to be used for that purpose.

Premises and Equipment
Premises and equipment are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line and accelerated methods over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized using the straight-line and accelerated methods over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter.
Long-Lived Asset Impairment
The Company evaluates the recoverability of the carrying value of long-lived assets whenever events or circumstances indicate the carrying amount may not be recoverable. If a long-lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset cost is adjusted to fair value and an impairment loss is recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value.
A valuation allowance of $1.2 million related to bank premises and furniture, fixtures and equipment was recorded during the year ended December 31, 2015, due to the Company's announced plans to consolidate operations of 14 banking centers into other nearby Great Southern banking center locations. The closing of these 14 facilities occurred at the close of business on January 8, 2016. During 2016, these assets were moved from furniture, fixtures and equipment to other real estate owned. A further valuation allowance of $430,000 related to these properties in other real estate owned not acquired through foreclosure was recorded during the year ended December 31, 2016, as the Company believed that the market value of some of these properties had declined further. No asset impairment was recognized during the year ended December 31, 2017.
Goodwill and Intangible Assets
Goodwill is evaluated annually for impairment or more frequently if impairment indicators are present. A qualitative assessment is performed to determine whether the existence of events or circumstances leads to a determination that it is more likely than not the fair value is less than the carrying amount, including goodwill. If, based on the evaluation, it is determined to be more likely than not that the fair value is less than the carrying value, then goodwill is tested further for impairment. If the implied fair value of goodwill is lower than its carrying amount, a goodwill impairment is indicated and goodwill is written down to its implied fair value. Subsequent increases in goodwill fair value are not recognized in the financial statements.
Intangible assets are being amortized on the straight-line basis generally over a period of seven years. Such assets are periodically evaluated as to the recoverability of their carrying value.

Loan Servicing and Origination Fee Income
Loan servicing income represents fees earned for servicing real estate mortgage loans owned by various investors. The fees are generally calculated on the outstanding principal balances of the loans serviced and are recorded as income when earned. Loan origination fees, net of direct loan origination costs, are recognized as income using the level-yield method over the contractual life of the loan.
Stockholders' Equity
The Company is incorporated in the State of Maryland. Under Maryland law, there is no concept of "Treasury Shares." Instead, shares purchased by the Company constitute authorized but unissued shares under Maryland law. Accounting principles generally accepted in the United States of America state that accounting for treasury stock shall conform to state law. The cost of shares purchased by the Company has been allocated to common stock and retained earnings balances.
Earnings Per Common Share
Basic earnings per common share are computed based on the weighted average number of common shares outstanding during each year. Diluted earnings per common share are computed using the weighted average common shares and all potential dilutive common shares outstanding during the period.

Options outstanding at December 31, 2017, 2016 and 2015, to purchase 253,711, 108,450 and 117,600 shares of common stock, respectively, were not included in the computation of diluted earnings per common share for each of the years because the exercise prices of such options were greater than the average market prices of the common stock for the years ended December 31, 2017, 2016 and 2015, respectively.
Stock Compensation Plans
The Company has stock-based employee compensation plans, which are described more fully in Note 21. In accordance with FASB ASC 718, Compensation – Stock Compensation, compensation cost related to share-based payment transactions is recognized in the Company's consolidated financial statements based on the grant-date fair value of the award using the modified prospective transition method. For the years ended December 31, 2017, 2016 and 2015, share-based compensation expense totaling $564,000, $483,000 and $382,000, respectively, was included in salaries and employee benefits expense in the consolidated statements of income.
Cash Equivalents
The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. At December 31, 2017 and 2016, cash equivalents consisted of interest-bearing deposits in other financial institutions. At December 31, 2017, nearly all of the interest-bearing deposits were uninsured with nearly all of these balances held at the Federal Home Loan Bank or the Federal Reserve Bank.
Income Taxes
The Company accounts for income taxes in accordance with income tax accounting guidance (FASB ASC 740, Income Taxes). The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of
124

Great Southern Bancorp, Inc.
Notes to Consolidated Financial Statements
December 31, 2017, 2016 and 2015
deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur.
Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term "more likely than not" means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management's judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. At December 31, 2017 and 2016, no valuation allowance was established.
The Company recognizes interest and penalties on income taxes as a component of income tax expense.
The Company files consolidated income tax returns with its subsidiaries.
Derivatives and Hedging Activities
FASB ASC 815, Derivatives and Hedging, provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items and (c) how derivative instruments and related hedged items affect an entity's financial position, financial performance and cash flows. Further, qualitative disclosures are required that explain the Company's objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. For detailed disclosures on derivatives and hedging activities, see Note 17.
As required by FASB ASC 815, the Company records all derivatives in the statement of financial condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting.
Restriction on Cash and Due From Banks
The Bank is required to maintain reserve funds in cash and/or on deposit with the Federal Reserve Bank. The reserve required at December 31, 2017 and 2016, respectively, was $59.1 million and $53.8 million.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606): Summary and Amendments that Create Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs--Contracts with Customers (Subtopic 340-40). The guidance in this Update supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the codification. These Updates were effective beginning January 1, 2018. Our revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. We have completed our evaluation of the impact of ASU 2014-09 on components of our non-interest income and have determined that certain components contain revenue streams which are included in the scope of these updates, such as deposit-related fees, service charges, debit card interchange fees and other charges and fees, and revenue from the sale of other real estate owned; however the adoption of these updates did not materially impact the Company's consolidated statements of income. We adopted the guidance using the modified retrospective adoption method, and no cumulative effect adjustment to opening retained earnings was required as a result of the adoption. The guidance in these Updates may result in new disclosure requirements, which will be included in the Company's March 31, 2018 Quarterly Report on Form 10-Q.
In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Topic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The Update requires investments in equity securities, except for those under the equity method of accounting, to be measured at fair value with changes in fair value recognized through net income. In addition, the Update requires separate presentation of financial assets and liabilities by measurement category, such as fair value through net income, fair value through other comprehensive income, or amortized cost on the balance sheet or in the notes to the financial statements. The Update also clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The Update was effective for the Company on January 1, 2018 and did not have a material impact on the Company's consolidated statements of financial condition or our consolidated statements of income. The Company does not currently hold any equity investments.
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments in this Update revise the accounting related to lessee accounting. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases. The Update is effective for the Company beginning in the first quarter of 2019, with early adoption permitted. Adoption of the standard requires the use of a modified retrospective transition approach for all periods presented at the time of adoption. Based on the Company's leases outstanding at December 31, 2017, which total less than 20 leased properties, we do not expect the new standard to have a material impact on our consolidated statements of financial condition or our consolidated statements of income, although an increase to assets and liabilities will occur at the time of adoption. The Company's new leases and lease modifications and renewals prior to the implementation date could impact the level of materiality.
In March 2016, the FASB issued ASU No. 2016-09, Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The Update amends several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Update was effective for the Company beginning January 1, 2017, and did not have a material effect on the Company's income taxes or the Company's consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326). The Update amends guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. For assets held at amortized cost basis, Topic 326 eliminates the probable initial recognition threshold in current GAAP and, instead, requires an entity to reflect its current estimate of all expected credit losses. This Update affects entities holding financial assets and net investment in leases that are not accounted for at fair value through net income. The amendments affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For public companies, the update is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption will be permitted beginning after December 15, 2018. An entity will apply the amendments in this update on a modified retrospective basis, through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company has formed a cross functional committee to oversee the system, data, reporting and other considerations for the purposes of meeting the requirements of this standard. We have assessed our data and system needs and are in the process of uploading the necessary historical loan data to the software that will be used in meeting certain requirements of this standard. The Company is evaluating the impact of adopting the new guidance, including the implementation of new data systems to capture the information needed to comply with the new standard. We expect to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, but cannot yet determine the magnitude of any such one-time adjustment, or the overall impact of the new guidance on the Company's consolidated financial statements.
In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230). The Update provides guidance on how certain cash receipts and payments are presented and classified in the statement of cash flows. These items include: cash payments for debt prepayment or debt extinguishment costs; cash outflows for the settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; and beneficial interests acquired in securitization transactions. The amendments in the Update are to be applied retrospectively. The Update was effective for the Company on January 1, 2018 and did not result in a material impact on the Company's consolidated financial statements, including the statement of cash flows.
In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740). The Update provides guidance on the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Under this guidance, companies will be required to recognize the income tax consequences of an intra-entity asset transfer when the transfer occurs. The Update was effective for the Company on January 1, 2018. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.
In January 2017, the FASB issued ASU No. 2017-01, Business Combinations - Clarifying the Definition of a Business (Topic 805). The amendments in this Update provide a more robust framework to use in determining when a set of assets and activities is a business. The amendments provide more consistency in applying the guidance, reduce the costs of application, and make the definition of a business more operable. The amendments in this Update were effective for the Company on January 1, 2018. The adoption of this new guidance must be applied on a prospective basis and did not have a material impact on the Company's consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles: Goodwill and Other: Simplifying the Test for Goodwill Impairment (Topic 350). To simplify the subsequent measurement of goodwill, the amendments eliminate Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test should be performed by comparing the fair value of a reporting unit with its carrying amount and an impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the qualitative impairment test is necessary. The nature of and reason for the change in accounting principle should be disclosed upon transition. The amendments in this update should be adopted for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted on testing dates after January 1, 2017. We are currently evaluating the impact of adopting the new guidance, including consideration of early adoption, on the consolidated financial statements, but it is not expected to have a material impact.
In March 2017, the FASB issued ASU No. 2017-08, Premium Amortization on Purchased Callable Debt Securities. The amendment shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date, rather than the contractual life of the security, which is typically used under current GAAP. The new guidance does not change the accounting for purchased callable debt securities held at a discount; the discount continues to be amortized to maturity. The amendments in this Update were to become effective for the Company for interim and annual reporting periods beginning after December 15, 2018; however, early adoption is permitted, and the Company elected to early adopt the ASU effective January 1, 2017. The adoption of the ASU did not have a material impact on the Company's consolidated financial statements.
In May 2017, the FASB issued ASU 2017-09, Compensation --Stock Compensation (Topic 718): Scope of Modification Accounting. The amendment provides guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 7l8. The amendments clarify that modification accounting only applies to an entity if the fair value, vesting conditions, or classification of the award changes as a result of changes in the terms or conditions of a share-based payment award. The ASU should be applied prospectively to awards modified on or after the adoption date. The guidance was effective for the Company on January 1, 2018. The adoption of the ASU did not impact the Company's consolidated financial statements.
In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The objective of ASU 2017-12 is to improve the financial reporting of hedging relationships by better aligning an entity's risk management activity with the economic objectives in undertaking those activities. In addition, the amendments in this update simplify the application of hedge accounting for preparers of financial statements, as well as improve the understandability of an entity's risk management activities being conveyed to financial statement users. The new guidance becomes effective for periods beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the new guidance and timing of adoption to determine the impact this standard may have on its financial statements.
In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220). The amendment allows an entity to elect to reclassify the stranded tax effects resulting from the change in income tax rate from H.R. 1, originally known as the "Tax Cuts and Jobs Act," from accumulated other comprehensive income to retained earnings. The amendments in this update are effective for periods beginning after December 15, 2018. Early adoption is permitted. The Company is still reviewing the amendments in the Update; however we anticipate that we could early

adopt ASU 2018-02 in the first quarter of 2018. Our stranded tax amount which will be reclassified from other comprehensive income to retained earnings at the time of adoption is estimated to be approximately $273,000.

Certain investments in debt securities are reported in the financial statements at an amount less than their historical cost. Total fair value of these investments at December 31, 2017 and 2016, was approximately $89.7 million and $104.5 million, respectively, which is approximately 50.0% and 48.8% of the Company's available-for-sale and held-to-maturity investment portfolio, respectively.
Based on evaluation of available evidence, including recent changes in market interest rates, credit rating information and information obtained from regulatory filings, management believes the declines in fair value for these debt securities are temporary.
The following table shows the Company's gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at December 31, 2017 and 2016:

Other-than-Temporary Impairment
Upon acquisition of a security, the Company decides whether it is within the scope of the accounting guidance for beneficial interests in securitized financial assets or will be evaluated for impairment under the accounting guidance for investments in debt and equity securities.
The accounting guidance for beneficial interests in securitized financial assets provides incremental impairment guidance for a subset of the debt securities within the scope of the guidance for investments in debt and equity securities. For securities where the security is a beneficial interest in securitized financial assets, the Company uses the beneficial interests in securitized financial asset impairment model. For securities where the security is not a beneficial interest in securitized financial assets, the Company uses the debt and equity securities impairment model. The Company does not currently have securities within the scope of this guidance for beneficial interests in securitized financial assets.
The Company routinely conducts periodic reviews to identify and evaluate each investment security to determine whether an other-than-temporary impairment has occurred. The Company considers the length of time a security has been in an unrealized loss position, the relative amount of the unrealized loss compared to the carrying value of the security, the type of security and other factors. If certain criteria are met, the Company performs additional review and evaluation using observable market values or various inputs in economic models to determine if an unrealized loss is other than temporary. The Company uses quoted market prices for marketable equity securities and uses broker pricing quotes based on observable inputs for equity investments that are not traded on a stock exchange. For nonagency collateralized mortgage obligations, to determine if the unrealized loss is other than temporary, the Company projects total estimated defaults of the underlying assets (mortgages) and multiplies that calculated amount by an estimate of realizable value upon sale in the marketplace (severity) in order to determine the projected collateral loss. The Company also evaluates any current credit enhancement underlying these securities to determine the impact on cash flows. If the Company determines that a given security position will be subject to a write-down or loss, the Company records the expected credit loss as a charge to earnings.
During 2017, 2016 and 2015, no securities were determined to have impairment that had become other than temporary.
Credit Losses Recognized on Investments
During 2017, 2016 and 2015, there were no debt securities that have experienced fair value deterioration due to credit losses, as well as due to other market factors, but are not otherwise other-than-temporarily impaired.

The weighted average interest rate on loans receivable at December 31, 2017 and 2016, was 4.74% and 4.58%, respectively.
Loans serviced for others are not included in the accompanying consolidated statements of financial condition. The unpaid principal balances of loans serviced for others were $254.0 million and $266.2 million at December 31, 2017 and 2016, respectively. In addition, available lines of credit on these loans were $37.8 million and $60.5 million at December 31, 2017 and 2016, respectively.
A loan is considered impaired, in accordance with the impairment accounting guidance (FASB ASC 310-10-35-16) when, based on current information and events, it is probable the Company will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include not only nonperforming loans but also loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties.
The following summarizes information regarding impaired loans at and during the years ended December 31, 2017, 2016 and 2015:

Notes to Consolidated Financial Statements
December 31, 2017, 2016 and 2015
At December 31, 2017, $12.7 million of impaired loans had specific valuation allowances totaling $4.0 million. At December 31, 2016, $18.1 million of impaired loans had specific valuation allowances totaling $6.4 million. At December 31, 2015, $25.1 million of impaired loans had specific valuation allowances totaling $6.1 million. For impaired loans which were nonaccruing, interest of approximately $1.2 million, $1.5 million and $1.0 million would have been recognized on an accrual basis during the years ended December 31, 2017, 2016 and 2015, respectively.
Included in certain loan categories in the impaired loans are troubled debt restructurings that were classified as impaired. Troubled debt restructurings are loans that are modified by granting concessions to borrowers experiencing financial difficulties. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. The types of concessions made are factored into the estimation of the allowance for loan losses for troubled debt restructurings primarily using a discounted cash flows or collateral adequacy approach.
The following table presents newly restructured loans during 2017, 2016 and 2015 by type of modification:

At December 31, 2017, the Company had $15.0 million of loans that were modified in troubled debt restructurings and impaired, as follows: $266,000 of construction and land development loans, $6.2 million of single family and multi-family residential mortgage loans, $7.1 million of commercial real estate loans, $867,000 million of commercial business loans and $617,000 of consumer loans. Of the total troubled debt restructurings at December 31, 2017, $12.3 million were accruing interest and $8.8 million were classified as substandard using the Company's internal grading system which is described below. The Company had no troubled debt restructurings which were modified in the previous 12 months and subsequently defaulted during the year ended December 31, 2017. When loans modified as troubled debt restructuring have subsequent payment defaults, the defaults are factored into the determination of the allowance for loan losses to ensure specific valuation allowances reflect amounts considered uncollectible. At December 31, 2016, the Company had $21.1 million of loans that were modified in troubled debt restructurings and impaired, as follows: $5.0 million of construction and land development loans, $7.4 million of single family and multi-family residential mortgage loans, $7.1 million of commercial real estate loans, $1.3 million of commercial business loans and $296,000 of consumer loans. Of the total troubled debt restructurings at December 31, 2016, $18.6 million were accruing interest and $7.9 million were classified as substandard using the Company's internal grading system. At December 31, 2015, the Company had $45.0 million of loans that were modified in troubled debt restructurings and impaired, as follows: $7.9 million of construction and land development loans, $13.5 million of single family and multi-family residential mortgage loans, $21.3 million of commercial real estate loans, $2.0 million of commercial business loans and $311,000 of consumer loans. Of the total troubled debt restructurings at December 31, 2015, $39.0 million were accruing interest and $12.2 million were classified as substandard using the Company's internal grading system.
During the year ended December 31, 2017, borrowers with loans designated as troubled debt restructurings totaling $998,000 met the criteria for placement back on accrual status. This criteria is generally a minimum of six months of consistent and timely payment performance under original or modified terms. The $998,000 was made up of $629,000 of residential mortgage loans, $285,000 of commercial real estate loans and $84,000 of consumer loans.
The Company reviews the credit quality of its loan portfolio using an internal grading system that classifies loans as "Satisfactory," "Watch," "Special Mention," "Substandard" and "Doubtful." Loans classified as watch are being monitored because of indications of potential weaknesses or deficiencies that
143

Great Southern Bancorp, Inc.
Notes to Consolidated Financial Statements
December 31, 2017, 2016 and 2015
may require future classification as special mention or substandard. Special mention loans possess potential weaknesses that deserve management's close attention but do not expose the Bank to a degree of risk that warrants substandard classification. Substandard loans are characterized by the distinct possibility that the Bank will sustain some loss if certain deficiencies are not corrected. Doubtful loans are those having all the weaknesses inherent to those classified Substandard with the added characteristics that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Loans not meeting any of the criteria previously described are considered satisfactory. The FDIC-assisted acquired loans are evaluated using this internal grading system. These loans are accounted for in pools. Minimal adverse classification in these acquired loan pools was identified as of December 31, 2017 and 2016, respectively. See Note 4 for further discussion of the acquired loan pools and termination of the loss sharing agreements.
The Company evaluates the loan risk internal grading system definitions and allowance for loan loss methodology on an ongoing basis. The general component of the allowance for loan losses is affected by several factors, including, but not limited to, average historical losses, average life of the loans, the current composition of the loan portfolio, current and expected economic conditions, collateral values and internal risk ratings. Management considers all these factors in determining the adequacy of the Company's allowance for loan losses. No significant changes were made to the loan risk grading system definitions and allowance for loan loss methodology during the past year.

Certain directors and executive officers of the Company and the Bank are customers of and had transactions with the Bank in the ordinary course of business. Except for the interest rates on loans secured by personal residences, in the opinion of management, all loans included in such transactions were made on substantially the same terms as those prevailing at the time for comparable transactions with unrelated parties. Generally, residential first mortgage loans and home equity lines of credit to all employees and directors have been granted at interest rates equal to the Bank's cost of funds, subject to annual adjustments in the case of residential first mortgage loans and monthly adjustments in the case of home equity lines of credit. At December 31, 2017 and 2016, loans outstanding to these directors and executive officers are summarized as follows:

Note 4: | Acquired Loans, Loss Sharing Agreements and FDIC Indemnification Assets

TeamBank
On March 20, 2009, Great Southern Bank entered into a purchase and assumption agreement with loss share with the Federal Deposit Insurance Corporation (FDIC) to assume all of the deposits (excluding brokered deposits) and acquire certain assets of TeamBank, N.A., a full service commercial bank headquartered in Paola, Kansas.
The loans, commitments and foreclosed assets purchased in the TeamBank transaction were covered by a loss sharing agreement between the FDIC and Great Southern Bank. This agreement originally was to extend for ten years for 1-4 family real estate loans and for five years for other loans. The five-year period ended March 31, 2014 and the ten-year period was terminated early, effective April 26, 2016, by mutual agreement of Great Southern Bank and the FDIC. See "Loss Sharing Agreements" below. Based upon the acquisition date fair values of the net assets acquired, no goodwill was recorded.
Vantus Bank
On September 4, 2009, Great Southern Bank entered into a purchase and assumption agreement with loss share with the FDIC to assume all of the deposits and acquire certain assets of Vantus Bank, a full service thrift headquartered in Sioux City, Iowa.
The loans, commitments and foreclosed assets purchased in the Vantus Bank transaction were covered by a loss sharing agreement between the FDIC and Great Southern Bank. This agreement originally was to extend for ten years for 1-4 family real estate loans and for five years for other loans. The five-year period ended September 30, 2014 and the ten-year period was terminated early, effective April 26, 2016, by mutual agreement of Great Southern Bank and the FDIC.

Sun Security Bank
On October 7, 2011, Great Southern Bank entered into a purchase and assumption agreement with loss share with the FDIC to assume all of the deposits and acquire certain assets of Sun Security Bank, a full service bank headquartered in Ellington, Missouri.
The loans and foreclosed assets purchased in the Sun Security Bank transaction were covered by a loss sharing agreement between the FDIC and Great Southern Bank. This agreement originally was to extend for ten years for 1-4 family real estate loans and for five years for other loans but was terminated early, effective April 26, 2016, by mutual agreement of Great Southern Bank and the FDIC. See "Loss Sharing Agreements" below. Based upon the acquisition date fair values of the net assets acquired, no goodwill was recorded.
InterBank
On April 27, 2012, Great Southern Bank entered into a purchase and assumption agreement with loss share with the FDIC to assume all of the deposits and acquire certain assets of Inter Savings Bank, FSB ("InterBank"), a full service bank headquartered in Maple Grove, Minnesota.
The loans and foreclosed assets purchased in the InterBank transaction were covered by a loss sharing agreement between the FDIC and Great Southern Bank. Under the loss sharing agreement, the FDIC agreed to cover 80% of the losses on the loans (excluding approximately $60,000 of consumer loans) and foreclosed assets purchased subject to certain limitations. Realized losses covered by the loss sharing agreement included loan contractual balances (and related unfunded commitments that were acquired), accrued interest on loans for up to 90 days, the book value of foreclosed real estate acquired, and certain direct costs, less cash or other consideration received by Great Southern. This agreement originally was to extend for ten years for 1-4 family real estate loans and for five years for other loans but was terminated early, effective June 9, 2017, by mutual agreement of Great Southern Bank and the FDIC. See "Loss Sharing Agreements" below. Based upon the acquisition date fair values of the net assets acquired, no goodwill was recorded. A premium was recorded in conjunction with the fair value of the acquired loans and the amount amortized to yield during 2017, 2016 and 2015 was $269,000, $359,000 and $459,000, respectively.
Valley Bank
On June 20, 2014, Great Southern Bank entered into a purchase and assumption agreement with the FDIC to purchase a substantial portion of the loans and investment securities, as well as certain other

assets, and assume all of the deposits, as well as certain other liabilities, of Valley Bank, a full-service bank headquartered in Moline, Illinois, with significant operations in Iowa. This transaction did not include a loss sharing agreement.
Based upon the acquisition date fair values of the net assets acquired, no goodwill was recorded. A premium was recorded in conjunction with the fair value of the acquired loans and the amount amortized to yield during 2017, 2016 and 2015 was $217,000, $491,000 and $794,000, respectively.
Loss Sharing Agreements
On April 26, 2016, Great Southern Bank executed an agreement with the FDIC to terminate the loss sharing agreements for TeamBank, Vantus Bank and Sun Security Bank, effective immediately. The agreement required the FDIC to pay $4.4 million to settle all outstanding items related to the terminated loss sharing agreements. As a result of entering into the agreement, assets that were covered by the terminated loss sharing agreements, including covered loans in the amount of $61.5 million and covered other real estate owned in the amount of $468,000 as of March 31, 2016, were reclassified as non-covered assets effective April 26, 2016. In anticipation of terminating the loss sharing agreements, an impairment of the related indemnification assets was recorded during the three months ended March 31, 2016 in the amount of $584,000. On the date of the termination, the indemnification asset balances (and certain other receivables from the FDIC) related to TeamBank, Vantus Bank and Sun Security Bank, which totaled $4.4 million, net of impairment, at March 31, 2016, became $-0- as a result of the receipt of funds from the FDIC as outlined in the termination agreement. There will be no future effects on non-interest income (expense) related to adjustments or amortization of the indemnification assets for TeamBank, Vantus Bank or Sun Security Bank; however, adjustments and amortization related to the InterBank indemnification asset and loss sharing agreement continued until their termination discussed below. The remaining accretable yield adjustments that affect interest income are not changed by this transaction and will continue to be recognized for all FDIC-assisted transactions in the same manner as they have been previously.
On June 9, 2017, Great Southern Bank executed an agreement with the FDIC to terminate the loss sharing agreements for InterBank, effective immediately. Pursuant to the termination agreement, the FDIC paid $15.0 million to the Bank to settle all outstanding items related to the terminated loss sharing agreements. The Company recorded a pre-tax gain on the termination of $7.7 million. As a result of entering into the termination agreement, assets that were covered by the terminated loss sharing arrangements, including covered loans in the amount of $138.8 million and covered other real estate owned in the amount of $2.9 million as of March 31, 2017, were reclassified as non-covered assets effective June 9, 2017. All rights and obligations of the Bank and the FDIC under the terminated loss sharing agreements, including the settlement of all existing loss sharing and expense reimbursement claims, have been resolved and terminated.
The termination of the loss sharing agreements for the TeamBank, Vantus Bank, Sun Security Bank and InterBank transactions have no impact on the yields for the loans that were previously covered under these agreements. All post-termination recoveries, gains, losses and expenses related to these previously covered assets are recognized entirely by Great Southern Bank since the FDIC no longer shares in such gains or losses. Accordingly, the Company's earnings are positively impacted to the extent the Company recognizes gains on any sales or recoveries in excess of the carrying value of such assets. Similarly, the Company's future earnings will be negatively impacted to the extent the Company recognizes expenses, losses or charge-offs related to such assets.

Fair Value and Expected Cash Flows
At the time of these acquisitions, the Company determined the fair value of the loan portfolios based on several assumptions. Factors considered in the valuations were projected cash flows for the loans, type of loan and related collateral, classification status, fixed or variable interest rate, term of loan, current discount rates and whether or not the loan was amortizing. Loans were grouped together according to similar characteristics and were treated in the aggregate when applying various valuation techniques. Management also estimated the amount of credit losses that were expected to be realized for the loan portfolios. The discounted cash flow approach was used to value each pool of loans. For non-performing loans, fair value was estimated by calculating the present value of the recoverable cash flows using a discount rate based on comparable corporate bond rates. This valuation of the acquired loans is a significant component leading to the valuation of the loss sharing assets recorded.
The amount of the estimated cash flows expected to be received from the acquired loan pools in excess of the fair values recorded for the loan pools is referred to as the accretable yield. The accretable yield is recognized as interest income over the estimated lives of the loans. The Company continues to evaluate the fair value of the loans including cash flows expected to be collected. Increases in the Company's cash flow expectations are recognized as increases to the accretable yield while decreases are recognized as impairments through the allowance for loan losses. During the years ended December 31, 2017, 2016 and 2015, improvements in expected cash flows related to the acquired loan portfolios resulted in adjustments to the accretable yield to be spread over the estimated remaining lives of the loans on a level-yield basis. The increases in expected cash flows also reduced the amount of expected reimbursements under the loss sharing agreements, when applicable, until they were terminated or expired. This resulted in corresponding adjustments during the years ended December 31, 2017, 2016 and 2015, to the indemnification assets (which have now been reduced to $-0- due to the termination of the loss sharing agreements). The amounts of these adjustments were as follows:

The adjustments, along with those made in previous years, impacted the Company's Consolidated Statements of Income as follows:

|  | Year Ended December 31, |
|  | 2017 |  |  | 2016 |  |  | 2015 |
|  | (In Thousands) |
Interest income |  | $ | 5,014 |  |  | $ | 16,393 |  |  | $ | 28,531 |
Noninterest income |  |  | (634 | ) |  |  | (7,033 | ) |  |  | (19,534 | )
Net impact to pre-tax income |  | $ | 4,380 |  |  | $ | 9,360 |  |  | $ | 8,997 |

On an on-going basis the Company estimates the cash flows expected to be collected from the acquired loan pools. For each of the loan portfolios acquired, the cash flow estimates have increased, based on payment histories and reduced credit loss expectations. This resulted in increased income that has been spread, on a level-yield basis, over the remaining expected lives of the loan pools (and, therefore, has decreased over time). The increases in expected cash flows also reduced the amount of expected reimbursements under the loss sharing agreements with the FDIC (when such agreements were in place), which were recorded as indemnification assets. Therefore, the expected indemnification assets had also been reduced each quarter since the fourth quarter of 2010, resulting in adjustments to be amortized on a comparable basis over the remainder of the loss sharing agreements or the remaining expected lives of the loan pools, whichever was shorter. Additional estimated cash flows totaling approximately $1.3 million were recorded in the year ended December 31, 2017 related to these loan pools, with no corresponding reduction in expected reimbursement from the FDIC as the remaining loss sharing agreements were terminated in 2017.
Because these adjustments will be recognized generally over the remaining lives of the loan pools, they will impact future periods as well. The remaining accretable yield adjustment that will affect interest income is $2.6 million. As there is no longer, nor will there be in the future, indemnification asset amortization related to TeamBank, Vantus Bank, Sun Security Bank or InterBank due to the termination or expiration of the related loss sharing agreements for those transactions, there is no remaining indemnification asset or related adjustments that will affect non-interest income (expense). Of the remaining adjustments affecting interest income, we expect to recognize $1.7 million of interest income during 2018. Additional adjustments may be recorded in future periods from the FDIC-assisted acquisitions, as the Company continues to estimate expected cash flows from the acquired loan pools.
The loss sharing asset was measured separately from the loan portfolio because it was not contractually embedded in the loans and was not transferable with the loans should the Bank have chosen to dispose of them. Fair value was estimated using projected cash flows available for loss sharing based on the credit adjustments estimated for each loan pool (as discussed above) and the loss sharing percentages outlined in the applicable Purchase and Assumption Agreement with the FDIC. These cash flows were discounted to reflect the uncertainty of the timing and receipt of the loss sharing reimbursement from the FDIC. The loss sharing asset was also separately measured from the related foreclosed real estate.
The loss sharing agreement on the InterBank transaction included a clawback provision whereby if credit loss performance was better than certain pre-established thresholds, then a portion of the monetary benefit was to be shared with the FDIC. The pre-established threshold for credit losses was $115.7

million for this transaction. The monetary benefit required to be paid to the FDIC under the clawback provision, if any, was to occur shortly after the termination of the loss sharing agreement, which in the case of InterBank was to be 10 years from the acquisition date.
At December 31, 2016 and 2015, the Bank's internal estimate of credit performance was expected to be better than the threshold set by the FDIC in the loss sharing agreement. Therefore, a separate clawback liability totaling $6.6 million and $6.6 million was recorded as of December 31, 2016 and 2015, respectively. This clawback liability was included in the calculation of the final settlement payment related to the termination of the InterBank loss sharing agreements.
TeamBank Loans and Foreclosed Assets. The following tables present the balances of the acquired loans and foreclosed assets related to the TeamBank transaction at December 31, 2017 and 2016. Through December 31, 2017, gross loan balances (due from the borrower) were reduced approximately $422.5 million since the transaction date because of $289.7 million of repayments by the borrower, $61.7 million of transfers to foreclosed assets and $71.1 million of charge-downs to customer loan balances. Based upon the collectability analyses performed at the time of the acquisition, we expected certain levels of foreclosures and charge-offs and actual results have been better than our expectations. As a result, cash flows expected to be received from the acquired loan pools have increased, resulting in adjustments that were made to the related accretable yield as described above.

Note 7: | Investments in Limited Partnerships

Investments in Affordable Housing Partnerships
The Company has invested in certain limited partnerships that were formed to develop and operate apartments and single-family houses designed as high-quality affordable housing for lower income tenants throughout Missouri and contiguous states. At December 31, 2017, the Company had 16 investments, with a net carrying value of $18.2 million. At December 31, 2016, the Company had 13 investments, with a net carrying value of $21.8 million. Due to the Company's inability to exercise any significant influence over any of the investments in Affordable Housing Partnerships, they all are accounted for using the proportional amortization method. Each of the partnerships must meet the regulatory requirements for affordable housing for a minimum 15-year compliance period to fully utilize the tax credits. If the partnerships cease to qualify during the compliance period, the credits may be denied for any period in which the projects are not in compliance and a portion of the credits previously taken may be subject to recapture with interest.
The remaining federal affordable housing tax credits to be utilized through 2023 were $40.0 million as of December 31, 2017, assuming no tax credit recapture events occur and all projects currently under construction are completed as planned. Amortization of the investments in partnerships is expected to be approximately $34.9 million, assuming all projects currently under construction are completed and funded as planned. The Company's usage of federal affordable housing tax credits approximated $6.6

million, $6.2 million and $6.3 million during 2017, 2016 and 2015, respectively. Investment amortization amounted to $5.2 million, $4.4 million and $4.9 million for the years ended December 31, 2017, 2016 and 2015, respectively.
Investments in Community Development Entities
The Company has invested in certain limited partnerships that were formed to develop and operate business and real estate projects located in low-income communities. At December 31, 2017, the Company had two investments, with a net carrying value of $940,000. At December 31, 2016, the Company had two investments, with a net carrying value of $1.9 million. Due to the Company's inability to exercise any significant influence over any of the investments in qualified Community Development Entities, they are all accounted for using the cost method. Each of the partnerships provides federal New Market Tax Credits over a seven-year credit allowance period. In each of the first three years, credits totaling five percent of the original investment are allowed on the credit allowance dates and for the final four years, credits totaling six percent of the original investment are allowed on the credit allowance dates. Each of the partnerships must be invested in a qualified Community Development Entity on each of the credit allowance dates during the seven-year period to utilize the tax credits. If the Community Development Entities cease to qualify during the seven-year period, the credits may be denied for any credit allowance date and a portion of the credits previously taken may be subject to recapture with interest. The investments in the Community Development Entities cannot be redeemed before the end of the seven-year period.
The remaining federal New Market Tax Credits to be utilized through 2019 were $960,000 as of December 31, 2017. Amortization of the investments in partnerships is expected to be approximately $730,000. The Company's usage of federal New Market Tax Credits approximated $1.2 million, $2.3 million and $2.3 million during 2017, 2016 and 2015, respectively. Investment amortization amounted to $930,000, $1.7 million and $1.7 million for the years ended December 31, 2017, 2016 and 2015, respectively.
Investments in Limited Partnerships for Federal Rehabilitation/Historic Tax Credits
From time to time, the Company has invested in certain limited partnerships that were formed to provide certain federal rehabilitation/historic tax credits. The Company utilizes these credits in their entirety in the year the project is placed in service and the impact to the Consolidated Statements of Income has not been material.
Investments in Limited Partnerships for State Tax Credits
From time to time, the Company has invested in certain limited partnerships that were formed to provide certain state tax credits. The Company has primarily syndicated these tax credits and the impact to the Consolidated Statements of Income has not been material.

Note 12: | Subordinated Debentures Issued to Capital Trusts

In November 2006, Great Southern Capital Trust II (Trust II), a statutory trust formed by the Company for the purpose of issuing the securities, issued a $25.0 million aggregate liquidation amount of floating rate cumulative trust preferred securities. The Trust II securities bear a floating distribution rate equal to 90-day LIBOR plus 1.60%. The Trust II securities became redeemable at the Company's option in February 2012, and if not sooner redeemed, mature on February 1, 2037. The Trust II securities were sold in a private transaction exempt from registration under the Securities Act of 1933, as amended. The gross proceeds of the offering were used to purchase Junior Subordinated Debentures from the Company totaling $25.8 million and bearing an interest rate identical to the distribution rate on the Trust II securities. The initial interest rate on the Trust II debentures was 6.98%. The interest rate was 2.98% and 2.49% at December 31, 2017 and 2016, respectively.
In July 2007, Great Southern Capital Trust III (Trust III), a statutory trust formed by the Company for the purpose of issuing the securities, issued a $5.0 million aggregate liquidation amount of floating rate cumulative trust preferred securities. The Trust III securities bore a floating distribution rate equal to 90-day LIBOR plus 1.40%. The Trust III securities were redeemable at the Company's option beginning October 2012, and if not sooner redeemed, matured on October 1, 2037. The Trust III securities were sold in a private transaction exempt from registration under the Securities Act of 1933, as amended. The gross proceeds of the offering were used to purchase Junior Subordinated Debentures from the Company totaling $5.2 million and bearing an interest rate identical to the distribution rate on the Trust III securities.
In July 2015, the Company was the successful bidder in an auction of the $5.0 million aggregate liquidation amount of floating rate cumulative trust preferred securities issued in 2007 by Great Southern Capital Trust III. The Company purchased the trust preferred securities at a discount, which resulted in a pre-tax gain of approximately $1.1 million. Subsequent to the purchase, which resulted in the Company's ownership of all of the outstanding common and preferred securities of Great Southern Capital Trust III, such securities were canceled and the principal amount of the Company's related debentures, which had equaled the aggregate liquidation amount of the outstanding common and preferred securities of Great Southern Capital Trust III, was reduced to zero.
At December 31, 2017 and 2016, subordinated debentures issued to capital trusts are summarized as follows:

Note 13: | Subordinated Notes

On August 8, 2016, the Company completed the public offering and sale of $75.0 million of its subordinated notes. The notes are due August 15, 2026, and have a fixed interest rate of 5.25% until August 15, 2021, at which time the rate becomes floating at a rate equal to three-month LIBOR plus 4.087%. The Company may call the notes at par beginning on August 15, 2021, and on any scheduled interest payment date thereafter. The notes were sold at par, resulting in net proceeds, after underwriting discounts and commissions, legal, accounting and other professional fees, of approximately $73.5

Note 14: | Income Taxes

The Company files a consolidated federal income tax return. As of December 31, 2017 and 2016, retained earnings included approximately $17.5 million for which no deferred income tax liability had been recognized. This amount represents an allocation of income to bad debt deductions for tax purposes only for tax years prior to 1988. If the Bank were to liquidate, the entire amount would have to be recaptured and would create income for tax purposes only, which would be subject to the then-current corporate income tax rate. The unrecorded deferred income tax liability on the above amount was approximately $3.9 million and $6.5 million at December 31, 2017 and 2016, respectively.
During the years ended December 31, 2017, 2016 and 2015, the provision for income taxes included these components:

The Company and its consolidated subsidiaries have not been audited recently by the Internal Revenue Service (IRS) and, as such, tax years through December 31, 2005, have been closed without audit. The Company, through one of its subsidiaries, is a partner in two partnerships which have been under Internal Revenue Service examination for 2006 and 2007. As a result, the Company's 2006 and subsequent tax years remain open for examination. The examinations of these partnerships advanced during 2016 and 2017. One of the partnerships has advanced to Tax Court and has entered a Motion for Entry of Decision with an agreed upon settlement. The other partnership examination was recently completed by the IRS with no change impacting the Company's tax positions. The Company does not currently expect significant adjustments to its financial statements from the partnership matter at the Tax Court.
The Company is currently under State of Missouri income and franchise tax examinations for its 2014 through 2015 tax years. The Company does not currently expect significant adjustments to its financial statements from this state examination. During 2017, the Company settled its appeal with the Kansas Department of Revenue. The settlement did not result in any significant adjustments to the Company's financial statements.

Note 15: | Disclosures About Fair Value of Financial Instruments

ASC Topic 820, Fair Value Measurements, defines fair value 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. Topic 820 also specifies a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

| · | Quoted prices in active markets for identical assets or liabilities (Level 1): Inputs that are quoted unadjusted prices in active markets for identical assets that the Company has the ability to access at the measurement date. An active market for the asset is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

| · | Other observable inputs (Level 2): Inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity including quoted prices for similar assets, quoted prices for securities in inactive markets and inputs derived principally from or corroborated by observable market data by correlation or other means.

| · | Significant unobservable inputs (Level 3): Inputs that reflect assumptions of a source independent of the reporting entity or the reporting entity's own assumptions that are supported by little or no market activity or observable inputs.

Financial instruments are broken down as follows by recurring or nonrecurring measurement status. Recurring assets are initially measured at fair value and are required to be remeasured at fair value in the financial statements at each reporting date. Assets measured on a nonrecurring basis are assets that, due to an event or circumstance, were required to be remeasured at fair value after initial recognition in the financial statements at some time during the reporting period.
The Company considers transfers between the levels of the hierarchy to be recognized at the end of related reporting periods.

There have been no significant changes in the valuation techniques during the year ended December 31, 2017.
Available-for-Sale Securities
Investment securities available for sale are recorded at fair value on a recurring basis. The fair values used by the Company are obtained from an independent pricing service, which represent either quoted market prices for the identical asset or fair values determined by pricing models, or other model-based valuation techniques, that consider observable market data, such as interest rate volatilities, LIBOR yield curve, credit spreads and prices from market makers and live trading systems. Recurring Level 1 securities include exchange traded equity securities. Recurring Level 2 securities include U.S. government agency securities, mortgage-backed securities, state and municipal bonds and certain other investments. Inputs used for valuing Level 2 securities include observable data that may include dealer quotes, benchmark yields, market spreads, live trading levels and market consensus prepayment speeds, among other things. Additional inputs include indicative values derived from the independent pricing service's proprietary computerized models. There were no recurring Level 3 securities at December 31, 2017 or 2016.

Interest Rate Derivatives
The fair value is estimated using forward-looking interest rate curves and is determined using observable market rates and, therefore, are classified within Level 2 of the valuation hierarchy.
Nonrecurring Measurements
The following tables present the fair value measurement of assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at December 31, 2017 and 2016:

Following is a description of the valuation methodologies used for assets measured at fair value on a nonrecurring basis and recognized in the accompanying statements of financial condition, as well as the general classification of such assets pursuant to the valuation hierarchy. For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below.
Loans Held for Sale
Mortgage loans held for sale are recorded at the lower of carrying value or fair value. The fair value of mortgage loans held for sale is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, the Company classifies mortgage loans held for sale as Nonrecurring Level 2. Write-downs to fair value typically do not occur as the Company generally enters into commitments to sell individual mortgage loans at the time the loan is originated to reduce market risk. The Company typically does not have commercial loans held for sale. At December 31, 2017 and 2016, the aggregate fair value of mortgage loans held for sale exceeded their cost. Accordingly, no mortgage loans held for sale were marked down and reported at fair value.
Impaired Loans
A loan is considered to be impaired when it is probable that all of the principal and interest due may not be collected according to its contractual terms. Generally, when a loan is considered impaired, the

December 31, 2017, 2016 and 2015
amount of reserve required under FASB ASC 310, Receivables, is measured based on the fair value of the underlying collateral. The Company makes such measurements on all material loans deemed impaired using the fair value of the collateral for collateral dependent loans. The fair value of collateral used by the Company is determined by obtaining an observable market price or by obtaining an appraised value from an independent, licensed or certified appraiser, using observable market data. This data includes information such as selling price of similar properties and capitalization rates of similar properties sold within the market, expected future cash flows or earnings of the subject property based on current market expectations, and other relevant factors. All appraised values are adjusted for market-related trends based on the Company's experience in sales and other appraisals of similar property types as well as estimated selling costs. Each quarter management reviews all collateral dependent impaired loans on a loan-by-loan basis to determine whether updated appraisals are necessary based on loan performance, collateral type and guarantor support. At times, the Company measures the fair value of collateral dependent impaired loans using appraisals with dates prior to one year from the date of review. These appraisals are discounted by applying current, observable market data about similar property types such as sales contracts, estimations of value by individuals familiar with the market, other appraisals, sales or collateral assessments based on current market activity until updated appraisals are obtained. Depending on the length of time since an appraisal was performed and the data provided through our reviews, these appraisals are typically discounted 10-40%. The policy described above is the same for all types of collateral dependent impaired loans.
The Company records impaired loans as Nonrecurring Level 3. If a loan's fair value as estimated by the Company is less than its carrying value, the Company either records a charge-off for the portion of the loan that exceeds the fair value or establishes a reserve within the allowance for loan losses specific to the loan. Loans for which such charge-offs or reserves were recorded during the years ended December 31, 2017 and 2016, are shown in the table above (net of reserves).
Foreclosed Assets Held for Sale
Foreclosed assets held for sale are initially recorded at fair value less estimated cost to sell at the date of foreclosure. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less estimated cost to sell. Foreclosed assets held for sale are classified within Level 3 of the fair value hierarchy. The foreclosed assets represented in the table above have been re-measured during the years ended December 31, 2017 and 2016, subsequent to their initial transfer to foreclosed assets.
The following disclosure relates to financial assets for which it is not practicable for the Company to estimate the fair value at December 31, 2017 and 2016.
FDIC Indemnification Asset
As part of certain Purchase and Assumption Agreements, the Bank and the FDIC entered into loss sharing agreements. These agreements covered realized losses on loans and foreclosed real estate subject to certain limitations which are more fully described in Note 4. All of these loss sharing agreements were mutually terminated by the Company and the FDIC during 2017 and 2016.

Notes to Consolidated Financial Statements
December 31, 2017, 2016 and 2015
Under the InterBank agreement, the FDIC agreed to reimburse the Bank for 80% of realized losses. The indemnification asset was originally recorded at fair value on the acquisition date (April 27, 2012) and at December 31, 2017 and 2016, the carrying value of the FDIC indemnification asset was $-0- million and $13.1 million, respectively.
The loss sharing assets were measured separately from the loan portfolios because they were not contractually embedded in the loans and were not transferable with the loans should the Bank have chosen to dispose of them. Fair values on the acquisition dates were estimated using projected cash flows available for loss sharing based on the credit adjustments estimated for each loan pool and the loss sharing percentages. These cash flows were discounted to reflect the uncertainty of the timing and receipt of the loss sharing reimbursements from the FDIC. The loss sharing assets were also separately measured from the related foreclosed real estate. Although the assets were contractual receivables from the FDIC, they did not have effective interest rates. The Bank collected the assets over several years. The amount ultimately collected was dependent on the timing and amount of collections and charge-offs on the acquired assets covered by the loss sharing agreements. While the assets were recorded at their estimated fair values on the acquisition dates, it was not practicable to complete fair value analyses on a quarterly or annual basis. Estimating the fair value of the FDIC indemnification asset would involve preparing fair value analyses of the entire portfolios of loans and foreclosed assets covered by the loss sharing agreements from all four acquisitions on a quarterly or annual basis. The loss sharing agreements for TeamBank, Vantus Bank and Sun Security Bank were terminated on April 26, 2016, and the carrying value of the related indemnification assets became $-0-. The loss sharing agreements for InterBank were terminated on June 9, 2017, and the carrying value of the related indemnification asset became $-0-. The termination of the loss sharing agreements is discussed in Note 4.
Fair Value of Financial Instruments
The following methods were used to estimate the fair value of all other financial instruments recognized in the accompanying statements of financial condition at amounts other than fair value.
Cash and Cash Equivalents and Federal Home Loan Bank Stock
The carrying amount approximates fair value.
Loans and Interest Receivable
The fair value of loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Loans with similar characteristics are aggregated for purposes of the calculations. The carrying amount of accrued interest receivable approximates its fair value.

December 31, 2017, 2016 and 2015
Deposits and Accrued Interest Payable
The fair value of demand deposits and savings accounts is the amount payable on demand at the reporting date, i.e., their carrying amounts. The fair value of fixed maturity certificates of deposit is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities. The carrying amount of accrued interest payable approximates its fair value.
Federal Home Loan Bank Advances
Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate fair value of existing advances.
Short-Term Borrowings
The carrying amount approximates fair value.
Subordinated Debentures Issued to Capital Trusts
The subordinated debentures have floating rates that reset quarterly. The carrying amount of these debentures approximates their fair value.
Subordinated Notes
The fair values used by the Company are obtained from independent sources and are derived from quoted market prices of the Company's subordinated notes and quoted market prices of other subordinated debt instruments with similar characteristics.
Commitments to Originate Loans, Letters of Credit and Lines of Credit
The fair value of commitments is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date.
The following table presents estimated fair values of the Company's financial instruments. The fair values of certain of these instruments were calculated by discounting expected cash flows, which method involves significant judgments by management and uncertainties. Fair value is the estimated amount at which financial assets or liabilities could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. Because no market exists for certain of these financial instruments and because management does not intend to sell these financial instruments, the Company does not know whether the fair values shown below represent values at which the respective financial instruments could be sold individually or in the aggregate.

Note 17: | Derivatives and Hedging Activities

Risk Management Objective of Using Derivatives
The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of its assets and liabilities. In the normal course of business, the Company may use derivative financial instruments (primarily interest rate swaps) from time to time to assist in its interest rate risk management. The Company has interest rate derivatives that result from a service provided to certain qualifying loan customers that are not used to manage interest rate risk in the Company's assets or liabilities and are not designated in a qualifying hedging relationship. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions. In addition, the Company has interest rate derivatives that are designated in a qualified hedging relationship.
Nondesignated Hedges
The Company has interest rate swaps that are not designated in a qualifying hedging relationship. Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain loan customers, which the Company began offering during 2011. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings.
As part of the Valley Bank FDIC-assisted acquisition, the Company acquired seven loans with related interest rate swaps. Valley's swap program differed from the Company's in that Valley did not have back to back swaps with the customer and a counterparty. Two of the seven acquired loans with interest rate swaps have paid off. The notional amount of the five remaining Valley swaps is $3.6 million at December 31, 2017. As of December 31, 2017, excluding the Valley Bank swaps, the Company had 22 interest rate swaps totaling $92.7 million in notional amount with commercial customers, and 22 interest rate swaps with the same notional amount with third parties related to its program. In addition, the Company has two participation loans purchased totaling $22.0 million, in which the lead institution has an interest rate swap with their customer and the economics of the counterparty swap are passed along to us through the loan participation. As of December 31, 2016, excluding the Valley Bank swaps, the Company had 26 interest rate swaps totaling $110.7 million in notional amount with commercial customers, and 26 interest rate swaps with the same notional amount with third parties related to its program. During the years ended December 31, 2017, 2016 and 2015, the Company recognized net gains and (losses) of $28,000, $66,000 and $(43,000), respectively, in noninterest income related to changes in the fair value of these swaps.
Cash Flow Hedges
As a strategy to maintain acceptable levels of exposure to the risk of changes in future cash flows due to interest rate fluctuations, the Company entered into two interest rate cap agreements for a portion of its floating rate debt associated with its trust preferred securities. One agreement, with a notional amount of $25 million, stated that the Company would pay interest on its trust preferred debt in accordance with
174

Great Southern Bancorp, Inc.
Notes to Consolidated Financial Statements
December 31, 2017, 2016 and 2015
the original debt terms at a rate of 3-month LIBOR + 1.60%. Should interest rates rise above a certain threshold, the counterparty would reimburse the Company for interest paid such that the Company would have an effective interest rate on that portion of its trust preferred securities no higher than 2.37%. The agreement became effective on August 1, 2013 and had a term of four years, which terminated during 2017. The other agreement, with a notional amount of $5 million, was terminated when the Company purchased the related trust preferred securities in July 2015. See Item 8, Financial Statements and Supplementary Information, in the Company's December 31, 2015 Annual Report on Form 10-K for more information on the trust preferred securities purchase transaction.
The effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. During the years ended December 31, 2017, 2016 and 2015, the Company recognized $-0- in noninterest income related to changes in the fair value of these derivatives. During the years ended December 31, 2017, 2016 and 2015, the Company recognized $293,000, $225,000 and $187,000, respectively, in interest expense related to the amortization of the cost of these interest rate caps. During the year ended December 31, 2015, one of the agreements was terminated early as noted above. As part of this termination, the remaining cost of the cash flow hedge, $95,000, was recognized as interest expense in 2015 (included in the $187,000 discussed here).

Agreements with Derivative Counterparties
The Company has agreements with its derivative counterparties. If the Company defaults on any of its indebtedness, including a default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. If the Bank fails to maintain its status as a well-capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. Similarly, the Company could be required to settle its obligations under certain of its agreements if certain regulatory events occurred, such as the issuance of a formal directive, or if the Company's credit rating is downgraded below a specified level.
As of December 31, 2017, the termination value of derivatives with our derivative dealer counterparties in a net liability position, which included accrued interest but excluded any adjustment for nonperformance risk, related to these agreements was $336,000. The Company has minimum collateral posting thresholds with its derivative dealer counterparties. At December 31, 2017, the Company's activity with its derivative dealer counterparties had met the level at which the minimum collateral posting thresholds take effect and the Company had posted $809,000 of collateral to satisfy the agreement. As of December 31, 2016, the termination value of derivatives with our derivative dealer counterparties in a net liability position, which included accrued interest but excluded any adjustment for nonperformance risk, related to these agreements was $1.6 million. At December 31, 2016, the Company's activity with its derivative dealer counterparties met the level in which the minimum collateral posting thresholds take effect and the Company had posted $6.0 million of collateral to satisfy the agreement. If the Company had breached any of these provisions at December 31, 2017 and 2016, it could have been required to settle its obligations under the agreements at the termination value.

Note 18: | Commitments and Credit Risk

Commitments to Originate Loans
Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a significant portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer's creditworthiness on a case‑by‑case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management's credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property and equipment, commercial real estate and residential real estate.
At December 31, 2017 and 2016, the Bank had outstanding commitments to originate loans and fund commercial construction loans aggregating approximately $164.0 million and $126.1 million, respectively. The commitments extend over varying periods of time with the majority being disbursed within a 30- to 180-day period.
Mortgage loans in the process of origination represent amounts that the Bank plans to fund within a normal period of 60 to 90 days, many of which are intended for sale to investors in the secondary market. Total mortgage loans in the process of origination amounted to approximately $20.8 million and $15.9 million at December 31, 2017 and 2016, respectively.

Letters of Credit
Standby letters of credit are irrevocable conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under nonfinancial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. Fees for letters of credit issued are initially recorded by the Bank as deferred revenue and are included in earnings at the termination of the respective agreements. Should the Bank be obligated to perform under the standby letters of credit, the Bank may seek recourse from the customer for reimbursement of amounts paid.
The Company had total outstanding standby letters of credit amounting to approximately $20.0 million and $26.4 million at December 31, 2017 and 2016, respectively, with $19.1 million and $25.1 million, respectively, of the letters of credit having terms up to five years and $885,000 and $1.3 million, respectively, of the letters of credit having terms over five years. Of the amount having terms over five years, $885,000 and $1.3 million at December 31, 2017 and 2016, respectively, consisted of an outstanding letter of credit to guarantee the payment of principal and interest on a Multifamily Housing Refunding Revenue Bond Issue.

The Company has purchased letters of credit from the Federal Home Loan Bank as security for certain public deposits. The amount of the letters of credit was $2.1 million and $2.1 million at December 31, 2017 and 2016, respectively, and they expire in less than one year from issuance.
Lines of Credit
Lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Lines of credit generally have fixed expiration dates. Since a portion of the line may expire without being drawn upon, the total unused lines do not necessarily represent future cash requirements. The Bank evaluates each customer's creditworthiness on a case‑by‑case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management's credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property and equipment, commercial real estate and residential real estate. The Bank uses the same credit policies in granting lines of credit as it does for on-balance-sheet instruments.
At December 31, 2017, the Bank had granted unused lines of credit to borrowers aggregating approximately $912.2 million and $133.6 million for commercial lines and open‑end consumer lines, respectively. At December 31, 2016, the Bank had granted unused lines of credit to borrowers aggregating approximately $658.4 million and $123.4 million for commercial lines and open‑end consumer lines, respectively.
Credit Risk
The Bank grants collateralized commercial, real estate and consumer loans primarily to customers in its market areas. Although the Bank has a diversified portfolio, loans (excluding those covered by loss sharing agreements) aggregating approximately $674.0 million and $677.3 million at December 31, 2017 and 2016, respectively, are secured primarily by apartments, condominiums, residential and commercial land developments, industrial revenue bonds and other types of commercial properties in the St. Louis, Missouri, area.

Note 20: | Employee Benefits

The Company participates in the Pentegra Defined Benefit Plan for Financial Institutions (Pentegra DB Plan), a multiemployer defined benefit pension plan covering all employees who have met minimum service requirements. Effective July 1, 2006, this plan was closed to new participants. Employees already in the plan continue to accrue benefits. The Pentegra DB Plan's Employer Identification Number is 13-5645888 and the Plan Number is 333. The Company's policy is to fund pension cost accrued. Employer contributions charged to expense for this plan for the years ended December 31, 2017, 2016 and 2015, were approximately $1.1 million, $725,000 and $742,000, respectively. The Company's contributions to the Pentegra DB Plan were not more than 5% of the total contributions to the plan. The funded status of the plan as of July 1, 2017 and 2016, was 98.2% and 98.5%, respectively. The funded status was calculated by taking the market value of plan assets, which reflected contributions received through June 30, 2017 and 2016, respectively, divided by the funding target. No collective bargaining agreements are in place that require contributions to the Pentegra DB Plan.
The Company has a defined contribution retirement plan covering substantially all employees. The Company matches 100% of the employee's contribution on the first 3% of the employee's compensation and also matches an additional 50% of the employee's contribution on the next 2% of the employee's compensation. Employer contributions charged to expense for this plan for the years ended December 31, 2017, 2016 and 2015, were approximately $1.3 million, $1.2 million and $951,000, respectively.

Note 21: | Stock Compensation Plans

The Company established the 2003 Stock Option and Incentive Plan (the "2003 Plan") for employees and directors of the Company and its subsidiaries. Under the plan, stock options or other awards could be granted with respect to 598,224 shares of common stock. On May 15, 2013, the Company's stockholders approved the Great Southern Bancorp, Inc. 2013 Equity Incentive Plan (the "2013 Plan"). Upon the stockholders' approval of the 2013 Plan, the Company's 2003 Plan was frozen. As a result, no new stock options or other awards may be granted under the 2003 Plan; however, existing outstanding awards under the 2003 Plan were not affected. At December 31, 2017, 126,042 options were outstanding under the 2003 Plan.

December 31, 2017, 2016 and 2015
The 2013 Plan provides for the grant from time to time to directors, emeritus directors, officers, employees and advisory directors of stock options, stock appreciation rights and restricted stock awards. The number of shares of Common Stock available for awards under the 2013 Plan is 700,000, all of which may be utilized for stock options and stock appreciation rights and no more than 100,000 of which may be utilized for restricted stock awards. At December 31, 2017, 556,757 options were outstanding under the 2013 Plan.
Stock options may be either incentive stock options or nonqualified stock options, and the option price must be at least equal to the fair value of the Company's common stock on the date of grant. Options generally are granted for a 10‑year term and generally become exercisable in four cumulative annual installments of 25% commencing two years from the date of grant. The Stock Option Committee may accelerate a participant's right to purchase shares under the plan.
Stock awards may be granted to key officers and employees upon terms and conditions determined solely at the discretion of the Stock Option Committee.

The Company's stock option grants contain terms that provide for a graded vesting schedule whereby portions of the options vest in increments over the requisite service period. These options typically vest one-fourth at the end of years two, three, four and five from the grant date. As provided for under FASB ASC 718, the Company has elected to recognize compensation expense for options with graded vesting schedules on a straight-line basis over the requisite service period for the entire option grant. In addition, ASC 718 requires companies to recognize compensation expense based on the estimated number of stock options for which service is expected to be rendered. The Company's historical forfeitures of its share-based awards have not been material.

December 31, 2017, 2016 and 2015
The fair value of each option award is estimated on the date of the grant using the Black-Scholes option pricing model with the following assumptions for the years ended December 31, 2017, 2016 and 2015:

|  | 2017 |  |  | 2016 |  |  | 2015 |
Expected dividends per share |  | $ | 0.95 |  |  | $ | 0.88 |  |  | $ | 0.88 |
Risk-free interest rate |  |  | 2.03 | % |  |  | 1.27 | % |  |  | 1.66 | %
Expected life of options |  | 5 years |  |  | 5 years |  |  | 5 years |
Expected volatility |  |  | 23.49 | % |  |  | 22.08 | % |  |  | 24.42 | %

options granted during year |  | $ | 10.04 |  |  | $ | 6.59 |  |  | $ | 9.59 |

Expected volatilities are based on the historical volatility of the Company's stock, based on the monthly closing stock price. The expected term of options granted is based on actual historical exercise behavior of all employees and directors and approximates the graded vesting period of the options. Expected dividends are based on the annualized dividends declared at the time of the option grant. The risk-free interest rate is based on the five-year treasury rate on the grant date of the options.
The following table presents the activity related to options under all plans for the year ended December 31, 2017:

Note 22: | Significant Estimates and Concentrations

Accounting principles generally accepted in the United States of America require disclosure of certain significant estimates and current vulnerabilities due to certain concentrations. Estimates related to the allowance for loan losses are reflected in Note 3. Estimates used in valuing acquired loans, loss sharing agreements and FDIC indemnification assets and in continuing to monitor related cash flows of acquired loans are discussed in Note 4. Current vulnerabilities due to certain concentrations of credit risk are discussed in the footnotes on loans, deposits and on commitments and credit risk.
Other significant estimates not discussed in those footnotes include valuations of foreclosed assets held for sale. The carrying value of foreclosed assets reflects management's best estimate of the amount to be realized from the sales of the assets. While the estimate is generally based on a valuation by an

independent appraiser or recent sales of similar properties, the amount that the Company realizes from the sales of the assets could differ materially in the near term from the carrying value reflected in these financial statements.

Note 24: | Regulatory Matters

The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can result in certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct and material effect on the Company's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company's and the Bank's assets, liabilities
183

Great Southern Bancorp, Inc.
Notes to Consolidated Financial Statements
December 31, 2017, 2016 and 2015
and certain off-balance-sheet items as calculated under U.S. GAAP, regulatory reporting practices, and regulatory capital standards. The Company's and the Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.
Quantitative measures established by regulatory reporting standards to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below as of December 31, 2017) of Total and Tier I Capital (as defined) to risk-weighted assets (as defined), of Tier I Capital (as defined) to adjusted tangible assets (as defined) and of Common Equity Tier 1 Capital (as defined) to risk-weighted assets (as defined). Management believes, as of December 31, 2017, that the Bank met all capital adequacy requirements to which it was then subject.
As of December 31, 2017, the most recent notification from the Bank's regulators categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized as of December 31, 2017, the Bank must have maintained minimum Total capital, Tier I capital, Tier 1 Leverage capital and Common Equity Tier 1 capital ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed the Bank's category.
The Company and the Bank are subject to certain restrictions on the amount of dividends that may be declared without prior regulatory approval. At December 31, 2017 and 2016, the Company and the Bank exceeded their minimum capital requirements then in effect. The entities may not pay dividends which would reduce capital below the minimum requirements shown above. In addition to the minimum capital ratios, the new capital rules include a capital conservation buffer, under which a banking organization must have CET1 more than 2.5% above each of its minimum risk-based capital ratios in order to avoid restrictions on paying dividends, repurchasing shares, and paying certain discretionary bonuses. The net unrealized gain or loss on available-for-sale securities is not included in computing regulatory capital.
The Company's and the Bank's actual capital amounts and ratios are presented in the following table. No amount was deducted from capital for interest-rate risk.

Note 25: | Litigation Matters

In the normal course of business, the Company and its subsidiaries are subject to pending and threatened legal actions, some of which seek substantial relief or damages. While the ultimate outcome of such legal proceedings cannot be predicted with certainty, after reviewing pending and threatened litigation with counsel, management believes at this time that, except as noted below, the outcome of such litigation will not have a material adverse effect on the Company's business, financial condition or results of operations.
On November 22, 2010, a suit was filed against the Bank in the Circuit Court of Greene County, Missouri by a customer alleging that the fees associated with the Bank's automated overdraft program in connection with its debit cards and ATM cards constitute unlawful interest in violation of Missouri's usury laws. The Court certified a class of Bank customers who paid overdraft fees on their checking accounts pursuant to the Bank's automated overdraft program. On October 5, 2017, relying on a Missouri Court of Appeals decision addressing similar claims, the Court granted the Bank's motion for summary judgment and entered judgment in the Bank's favor on all of plaintiff's claims. The time for plaintiff to seek appellate review expired on November 14, 2017, with no further action taken by plaintiff.

Note 28: | Preferred Stock

On August 18, 2011, the Company entered into a Small Business Lending Fund-Securities Purchase Agreement (the "SBLF Purchase Agreement") with the Secretary of the Treasury, pursuant to which the Company sold 57,943 shares of the Company's Senior Non-Cumulative Perpetual Preferred Stock, Series A (the "SBLF Preferred Stock") to the Secretary of the Treasury for a purchase price of $57.9 million. The SBLF Preferred Stock was issued pursuant to Treasury's SBLF program, a $30 billion fund established under the Small Business Jobs Act of 2010 that was created to encourage lending to small businesses by providing Tier 1 capital to qualified community banks and holding companies with assets of less than $10 billion. As required by the SBLF Purchase Agreement, the proceeds from the sale of the SBLF Preferred Stock were used in connection with the redemption of all 58,000 shares of the Company's preferred stock, issued to Treasury in December 2008 pursuant to Treasury's TARP Capital Purchase Program (the "CPP Preferred Stock"). The shares of CPP Preferred Stock were redeemed at their liquidation amount of $1,000 per share plus the accrued but unpaid dividends to the redemption date.
The SBLF Preferred Stock qualified as Tier 1 capital. The holders of SBLF Preferred Stock were entitled to receive noncumulative dividends, payable quarterly, on each January 1, April 1, July 1 and October 1. The dividend rate, as a percentage of the liquidation amount, could fluctuate between one percent (1%) and five percent (5%) per annum on a quarterly basis during the first 10 quarters during which the SBLF Preferred Stock was outstanding, based upon changes in the level of "Qualified Small Business Lending" or "QSBL" (as defined in the SBLF Purchase Agreement) by the Bank over the adjusted baseline level calculated under the terms of the SBLF Preferred Stock $(249.7 million). Based upon the increase in the Bank's level of QSBL over the adjusted baseline level, the dividend rate had been 1.0%. For the tenth calendar quarter through four and one-half years after issuance, the dividend

rate was fixed at between one percent (1%) and seven percent (7%) based upon the level of qualifying loans. The Company's dividend rate was 1.0% during 2015, and was expected to remain at 1% until four and one half years after the issuance, which is March 2016. After four and one half years from issuance, the dividend rate would have increased to 9% (including a quarterly lending incentive fee of 0.5%).
On December 15, 2015, the Company (with the approval of its federal banking regulator) redeemed all 57,943 shares of the SBLF Preferred Stock at their liquidation amount of $1,000 per share plus accrued but unpaid dividends to the redemption date. The redemption of the SBLF Preferred Stock was completed using internally available funds.

Note 29: | Consolidation of Banking Centers

On September 24, 2015, the Company announced plans to consolidate operations of 16 banking centers into other nearby Great Southern banking center locations. As part of an ongoing performance review of its entire banking center network, Great Southern evaluated each location for a number of criteria, including access and availability of services to affected customers, the proximity of other Great Southern banking centers, profitability and transaction volumes, and market dynamics. This review culminated in the approval of the consolidation of these banking centers by the Great Southern Board of Directors. Subsequent to this announcement, the Bank entered into separate definitive agreements to sell two of the 16 banking centers, including all of the associated deposits (totaling approximately $20 million), to separate bank purchasers. The sale of one of the banking centers was completed on February 19, 2016 and the sale of the other banking center was completed on March 18, 2016. The closing of the remaining 14 facilities, which resulted in the transfer of approximately $127 million in deposits and banking center operations to other Great Southern locations, occurred at the close of business on January 8, 2016.

Note 30: | Acquisition of Loans, Deposits and Branches

On September 30, 2015, the Company announced that it entered into a purchase and assumption agreement to acquire 12 branches and related deposits and loans in the St. Louis, Mo., area from Cincinnati-based Fifth Third Bank. The acquisition was completed at the close of business on January 29, 2016.
The deposits assumed totaled approximately $228 million and had a weighted average rate of approximately 0.28%, the composition of which was: demand deposits and NOW accounts – 42%; money market accounts – 40%; and time deposits and IRAs – 18%.
The loans acquired totaled approximately $159 million and had a weighted average yield of approximately 3.92%, the composition of which was: one- to four-family residential – 75%; commercial real estate – 8%; home equity lines – 10%; commercial business – 5%; and consumer and other – 2%. The one- to four-family residential loans are primarily loans made to professional individuals in the St. Louis market, such as doctors and persons working in the field of medicine. Approximately 55% of the total balance of these loans have fixed rates of interest for varying terms up to 30 years. Approximately 45% of the total balance of these loans have rates of interest that are fixed for varying terms (generally three to seven years), with rates that adjust annually thereafter.

ITEM 9. | CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

None.

ITEM 9A. | CONTROLS AND PROCEDURES.

We maintain a system of disclosure controls and procedures (as defined in Rule 13(a)-15(e) under the Securities Exchange Act (the "Exchange Act")) that is designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file under the Exchange Act is recorded, processed, summarized and reported accurately and within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate. An evaluation of our disclosure controls and procedures was carried out as of December 31, 2017, under the supervision and with the participation of our principal executive officer, principal financial officer and several other members of our senior management. Our principal executive officer and principal financial officer concluded that, as of December 31, 2017, our disclosure controls and procedures were effective in ensuring that the information we are required to disclose in the reports we file or submit under the Act is (i) accumulated and communicated to our management (including the principal executive officer and principal financial officer) to allow timely decisions regarding required disclosure, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms.
There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Act) that occurred during the quarter ended December 31, 2017, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. The annual report of management on the effectiveness of internal control over financial reporting and the attestation report thereon issued by our independent registered public accounting firm are set forth below under "Management's Report on Internal Control Over Financial Reporting" and "Report of the Independent Registered Public Accounting Firm."
We do not expect that our internal control over financial reporting will prevent all errors and all fraud. A control procedure, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control procedure are met. Because of the inherent limitations in all control procedures, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns in controls or procedures can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any control procedure also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control procedure, misstatements due to error or fraud may occur and not be detected.
MANAGEMENT'S REPORT ON INTERNAL CONTROL
OVER FINANCIAL REPORTING
The management of Great Southern Bancorp, Inc. (the "Company") is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). The Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. The Company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company's assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. All internal control systems, no matter how well designed, have inherent limitations, including the possibility of human error and the circumvention of overriding controls. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2016, based on the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013). Based on that assessment, management concluded that, as of December 31, 2017, the Company's internal control over financial reporting was effective.
The Company's internal control over financial reporting as of December 31, 2017, has been audited by BKD, LLP, an independent registered public accounting firm. Their attestation report on the effectiveness of the Company's internal control over financial reporting as of December 31, 2017 is set forth below.
Report of Independent Registered Public Accounting Firm
Audit Committee, Board of Directors and Stockholders
Great Southern Bancorp, Inc.
Springfield, Missouri
Opinion on the Internal Control over Financial Reporting
We have audited Great Southern Bancorp, Inc.'s (the "Company") internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the consolidated financial statements of the Company and our report dated March 6, 2018, expressed an unqualified opinion thereon.
Basis for Opinion
The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.
We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definitions and Limitations of Internal Control over Financial Reporting
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.
