Business Combination Policy:
Business Combination Policy	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. A detailed discussion of this transaction is included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009, under the section titled “Item 8. Financial Statements and Supplementary Information.” The loans, commitments and foreclosed assets purchased in the TeamBank transaction are covered by a loss sharing agreement between the FDIC and Great Southern Bank which affords the Bank at least 80% protection against losses. Under the loss sharing agreement, the Bank will share in the losses on assets covered under the agreement (referred to as covered assets). On losses up to $115.0 million, the FDIC has agreed to reimburse the Bank for 80% of the losses. On losses exceeding $115.0 million, the FDIC has agreed to reimburse the Bank for 95% of the losses. Realized losses covered by the loss sharing agreement include 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 the Bank. This agreement extends for ten years for 1-4 family real estate loans and for five years for other loans. The value of this loss sharing agreement was considered in determining fair values of loans and foreclosed assets acquired. The loss sharing agreement is subject to the Bank following servicing procedures as specified in the agreement with the FDIC. The expected reimbursements under the loss sharing agreement were recorded as an indemnification asset at their preliminary estimated fair value on the acquisition date. Based upon the acquisition date fair values of the net assets acquired, no goodwill was recorded. A discount was recorded in conjunction with the fair value of the acquired loans and the amount accreted to yield during the three and six months ended June 30, 2012 was $348,000 and $775,000, respectively. The amount accreted to yield during the three and six months ended June 30, 2011 was $668,000 and $1.4 million, respectively. 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. A detailed discussion of this transaction is included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009, under the section titled “Item 8. Financial Statements and Supplementary Information.” The loans, commitments and foreclosed assets purchased in the Vantus Bank transaction are covered by a loss sharing agreement between the FDIC and Great Southern Bank which affords the Bank at least 80% protection against losses. Under the loss sharing agreement, the Bank will share in the losses on assets covered under the agreement (referred to as covered assets). On losses up to $102.0 million, the FDIC has agreed to reimburse the Bank for 80% of the losses. On losses exceeding $102.0 million, the FDIC has agreed to reimburse the Bank for 95% of the losses. Realized losses covered by the loss sharing agreement include 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 the Bank. This agreement extends for ten years for 1-4 family real estate loans and for five years for other loans. The value of this loss sharing agreement was considered in determining fair values of loans and foreclosed assets acquired. The loss sharing agreement is subject to the Bank following servicing procedures as specified in the agreement with the FDIC. The expected reimbursements under the loss sharing agreement were recorded as an indemnification asset at their preliminary estimated fair value on the acquisition date. Based upon the acquisition date fair values of the net assets acquired, no goodwill was recorded. A discount was recorded in conjunction with the fair value of the acquired loans and the amount accreted to yield during the three and six months ended June 30, 2012 was $104,000 and $262,000, respectively. The amount accreted to yield during the three and six months ended June 30, 2011 was $247,000 and $523,000, respectively. 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. A detailed discussion of this transaction is included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011, under the section titled “Item 8. Financial Statements and Supplementary Information.” The loans and foreclosed assets purchased in the Sun Security Bank transaction are covered by a loss sharing agreement between the FDIC and Great Southern Bank. Under the loss sharing agreement, the FDIC has agreed to cover 80% of the losses on the loans (excluding approximately $4 million of consumer loans) and foreclosed assets purchased subject to certain limitations. Realized losses covered by the loss sharing agreement include 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 extends for ten years for 1-4 family real estate loans and for five years for other loans. The value of this loss sharing agreement was considered in determining fair values of loans and foreclosed assets acquired. The loss sharing agreement is subject to the Bank following servicing procedures as specified in the agreement with the FDIC. The expected reimbursements under the loss sharing agreement were recorded as an indemnification asset at their preliminary estimated fair value on the acquisition date. Based upon the acquisition date fair values of the net assets acquired, no goodwill was recorded. The Bank recorded the fair value of the acquired loans at their estimated fair value on the acquisition date. The Company’s estimates of its cash flows to be collected regarding the Sun Security assets has not materially changed. A discount was recorded in conjunction with the fair value of the acquired loans and the amount accreted to yield during the three and six months ended June 30, 2012 was $373,000 and $652,00, respectively. 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. Established in 1965, InterBank operated four locations in three counties in the Minneapolis-St. Paul area. Great Southern Bank assumed deposits with a fair value of $456.3 million at no premium and purchased loans with a fair value of $285.5 million and foreclosed assets with a fair value of $6.2 million at a discount of $59.9 million. The loans and foreclosed assets purchased in the InterBank transaction are covered by a loss sharing agreement between the FDIC and Great Southern Bank. Under the loss sharing agreement, the FDIC has 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 include 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 extends for ten years for 1-4 family real estate loans and for five years for other loans. The value of this loss sharing agreement was considered in determining fair values of loans and foreclosed assets acquired. The loss sharing agreement is subject to the Bank following servicing procedures as specified in the agreement with the FDIC. The expected reimbursements under the loss sharing agreement were recorded as an indemnification asset at their preliminary estimated fair value on the acquisition date. Based upon the acquisition date fair values of the net assets acquired, no goodwill was recorded. The Bank recorded the fair value of the acquired loans at their estimated fair value on the acquisition date. The Company’s estimates of its cash flows to be collected regarding the InterBank assets has not materially changed. A premium was recorded in conjunction with the fair value of the acquired loans and the amount amortized to yield during the three and six months ended June 30, 2012 was $194,000. *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 three and six months ended June 30, 2012, increases in expected cash flows related to the TeamBank, Vantus Bank and Sun Security Bank acquired loan portfolios resulted in adjustments of $8.8 million and $10.0 million, respectively, to the accretable yield to be spread over the estimated remaining lives of the loans on a level-yield basis. During the three and six months ended June 30, 2011, similar such adjustments totaling $7.9 million and $11.3 million, respectively, were made to the accretable yield. The current year increases in expected cash flows also reduced the amount of expected reimbursements under the loss sharing agreements. During the three and six months ended June 30, 2012, this resulted in a corresponding adjustment of $7.1 million and $8.0 million, respectively, to the indemnification assets to be amortized on a level-yield basis over the remainder of the loss sharing agreements or the remaining expected lives of the loan pools, whichever is shorter. Because these adjustments will be recognized over the remaining lives of the loan pools and the remainder of the loss sharing agreements, respectively, they will impact future periods as well. The remaining accretable yield adjustment that will affect interest income is $14.0 million and the remaining adjustment to the indemnification assets that will affect non-interest income (expense) is $(11.6) million. Of the remaining adjustments, we expect to recognize $9.0 million of interest income and $(7.7) million of non-interest income (expense) in the remainder of 2012. Additional adjustments may be recorded in future periods from the 2009, 2011 and 2012 acquisitions, as the Company continues to estimate expected cash flows from the acquired loan pools. The impact of adjustments on the Company’s financial results is shown below:

- Definition

Disclosure of accounting policy for completed business combinations (purchase method, acquisition method or combination of entities under common control). This accounting policy may include a general discussion of the purchase method or acquisition method of accounting (including for example, the treatment accorded contingent consideration, the identification of assets and liabilities, the purchase price allocation process, how the fair values of acquired assets and liabilities are determined) and the entity's specific application thereof. An entity that acquires another entity in a leveraged buyout transaction generally discloses the accounting policy followed by the acquiring entity in determining the basis used to value its interest in the acquired entity, and the rationale for that accounting policy.
