Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of NASB Financial, Inc. (the “Company”), its wholly-owned subsidiary, North American Savings Bank, F.S.B. (the “Bank”), and the Bank’s wholly-owned subsidiary, Nor-Am Service Corporation. All significant inter-company transactions have been eliminated in consolidation. The consolidated financial statements do not include the accounts of our wholly owned statutory trust, NASB Preferred Trust I (the “Trust”). The Trust qualifies as a special purpose entity that is not required to be consolidated in the financial statements of NASB Financial, Inc. The Trust Preferred Securities issued by the Trust are included in Tier I capital for regulatory capital purposes.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand plus interest-bearing deposits in the Federal Home Loan Bank of Des Moines totaling $3.5 million and $5.7 million as of September 30, 2013 and 2012, respectively. The Federal Reserve Board (“FRB”) requires federally chartered savings banks to maintain non-interest-earning cash reserves at specified levels against their transaction accounts. Required reserves may be maintained in the form of vault cash, a non-interest-bearing account at a Federal Reserve Bank, or a pass-through account, as defined by FRB. At September 30, 2013, the Bank’s reserve requirement was $4.1 million.

Securities and Mortgage-Backed Securities

Securities and mortgage-backed securities are classified as held to maturity when the Company has the positive intent and ability to hold the securities to maturity. Securities and mortgage-backed securities not classified as held to maturity or trading are classified as available for sale. As of September 30, 2013 and 2012, the Company had no assets designated as trading. Securities and mortgage-backed securities held to maturity are stated at cost. Securities and mortgage-backed securities classified as available for sale are recorded at their fair values, with unrealized gains and losses, net of income taxes, reported as accumulated other comprehensive income or loss.

Premiums and discounts are recognized as adjustments to interest income over the life of the securities using a method that approximates the level yield method. Gains or losses on the disposition of securities are based on the specific identification method. Securities are valued using market prices in an active market, if available. Less frequently traded securities are valued using industry standard models which utilize various assumptions such as historical prices of the same or similar securities, and observation of market prices of securities of the same issuer, market prices of same-sector issuers, and fixed income indexes. Mortgage-backed securities are valued by using industry standard models which utilize various inputs and assumptions such as historical prices of benchmark securities, prepayment estimates, loan type, and year of origination.

Management monitors the securities and mortgage-backed securities portfolios for impairment on an ongoing basis. This process involves monitoring market conditions and other relevant information, including external credit ratings, to determine whether or not a decline in value is other-than-temporary. If management intends to sell an impaired security or mortgage-backed security, or if it is more likely than not that management will be required to sell the impaired security prior to recovery of its amortized cost basis, the Bank will recognize a loss in earnings. If management does not intend to sell a debt security or mortgage-backed security, or if it is more likely than not that management will not be required to sell the impaired security prior to recovery of its amortized cost, regardless of whether the security is classified as available for sale or held to maturity, the Bank will recognize the credit component of the loss in earnings and the remaining portion in other comprehensive income. The credit loss component recognized in earnings is the amount of principal cash flows not expected to be received over the remaining life of the security. The amount of other-than temporary-impairment included in other comprehensive income is amortized over the remaining life of the security.

Loans Receivable Held for Sale

As the Bank originates loans each month, management evaluates the existing market conditions to determine which loans will be held in the Bank’s portfolio and which loans will be sold in the secondary market. Loans sold in the secondary market are sold with servicing released or converted into mortgage-backed securities (“MBS”) and sold with the servicing retained by the Bank. At the time of each loan commitment, a decision is made to either hold the loan for investment, hold it for sale with servicing retained, or hold it for sale with servicing released. Management monitors market conditions to decide whether loans should be held in the portfolio or sold and if sold, which method of sale is appropriate.

Loans held for sale are carried at fair value. Gains or losses on such sales are recognized using the specific identification method. The transfer of a loan receivable held for sale is accounted for as a sale when control over the asset has been surrendered. The Bank issues various representations and warranties and standard recourse provisions associated with the sale of loans, which are described more fully in Footnote 6.

Loans Receivable Held for Investment, Net

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at the amount of unpaid principal less an allowance for loan losses, undisbursed loan funds and unearned discounts and loan fees, net of certain direct loan origination costs. Interest on loans is credited to income as earned and accrued only when it is deemed collectible. Loans are placed on nonaccrual status when, in the opinion of management, the full timely collection of principal or interest is in doubt. The accrual of interest is discontinued when principal or interest payments become doubtful. As a general rule, this occurs when the loan becomes ninety days past due. When a loan is placed on nonaccrual status, previously accrued but unpaid interest is reversed against current income. Subsequent collections of cash may be applied as reductions to the principal balance, interest in arrears or recorded as income, depending on Bank management’s assessment of the ultimate collectability of the loan. Nonaccrual loans may be restored to accrual status when principal and interest become current and the full payment of principal and interest is expected.

A loan becomes impaired when management believes it will be unable to collect all principal and interest due according to the contractual terms of the loan. A restructuring of debt is considered a TDR if, because of a debtor’s financial difficulty, a creditor grants concessions that it would not otherwise consider. Loans modified in troubled debt restructurings are also considered impaired. Concessions granted in a TDR could include a reduction in interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. Once a loan has been deemed impaired, the impairment must be measured by comparing the recorded investment in the loan to the present value of the estimated future cash flows discounted at the loan’s effective rate, or to the fair value of the loan based on the loan’s observable market price, or to the fair value of the collateral if the loan is collateral dependent. Unless the loan is performing prior to the restructure, TDRs are placed in non-accrual status at the time of restructuring and may only be returned to performing status after the borrower demonstrates sustained repayment performance for a reasonable period, generally six months.

Net loan fees and direct loan origination costs are deferred and amortized as yield adjustments to interest income using the level-yield method over the contractual lives of the related loans.

Allowance for Loan Losses

The Bank considers a loan to be impaired when management believes it will be unable to collect all principal and interest due according to the contractual terms of the loan. If a loan is impaired, the Bank records a loss valuation equal to the excess of the loan’s carrying value over the present value of the estimated future cash flows discounted at the loan’s initial effective rate, or the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. One-to-four family residential loans and consumer loans are collectively evaluated for impairment. Loans on residential properties with greater than four units, on construction and development and commercial properties are evaluated for impairment on a loan by loan basis. The allowance for loan losses is increased by charges to income and decreased by charge-offs (net of recoveries). Management’s periodic evaluation of the adequacy of the allowance is based on the Bank’s past loan loss experience, known and inherent losses in the portfolio, and various subjective factors such as economic and business conditions. 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 that may be susceptible to significant change. In management’s opinion, the allowance, when taken as a whole, is adequate to absorb reasonable estimated loan losses inherent in the Bank’s loan portfolio.

Foreclosed Assets Held for Sale

Foreclosed assets held for sale are initially recorded at fair value as of the date of foreclosure less any estimated selling costs (the “new basis”) and are subsequently carried at the lower of the new basis or fair value less selling costs on the current measurement date. When foreclosed assets are acquired any excess of the loan balance over the new basis of the foreclosed asset is charged to the allowance for loan losses. Subsequent adjustments for estimated losses are charged to operations when the fair value declines to an amount less than the carrying value. Costs and expenses related to major additions and improvements are capitalized, while maintenance and repairs that do not improve or extend the lives of the respective assets are expensed. Applicable gains and losses on the sale of real estate owned are realized when the asset is disposed of, depending on the adequacy of the down payment and other requirements.

Premises and Equipment

Premises and equipment are recorded at cost, less accumulated depreciation. Depreciation of premises and equipment is provided over the estimated useful lives (from three to forty years for buildings and improvements and from three to ten years for furniture, fixtures, and equipment) of the respective assets using the straight-line method. Maintenance and repairs are charged to expense. Major renewals and improvements are capitalized. Gains and losses on dispositions are credited or charged to earnings as incurred.

Investment in LLCs

The Company is a partner in two limited liability companies, which were formed for the purpose of purchasing and developing vacant land in Platte County, Missouri. These investments are accounted for using the equity method of accounting.

Goodwill

The Company has goodwill of $1.8 million at September 30, 2013 and 2012. This asset, which resulted from the Bank’s acquisition of CBES Bancorp, Inc. in fiscal 2003, was assigned to the banking segment of the business. In accordance with GAAP, the Company tests its goodwill for impairment annually, or more frequently if events indicate that the asset might be impaired. The first step of the goodwill impairment test compares the fair value of a reporting segment with its carrying amount, including goodwill. If the carrying value of a reporting unit exceeds its fair value, a second step of the goodwill impairment test is required, which compares the implied fair value of reporting unit goodwill to its carrying value. The implied fair value is determined in the same manner as the amount of goodwill recognized in a business combination is determined. At September 30, 2013 and 2012, the Company’s stock price was in excess of its book value per share; thus, the Company did not perform the second step of the goodwill impairment test as of that date.

The Company has a stock-based employee compensation plan which is described more fully in Footnote 17, Stock Option Plan. The Company recognizes compensation cost over the five-year service period for its stock option awards. Stock based compensation related to stock options totaled $(44,000), $5,000 and $49,000 during the years ended September 30, 2013, 2012 and 2011, respectively.

Income Taxes

The Company files a consolidated Federal income tax return with its subsidiaries using the accrual method of accounting.

The Company provides for income taxes using the asset/liability method. Deferred income taxes are recognized for the tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities.

The Bank’s bad debt deduction for the years ended September 30, 2013, 2012 and 2011, was based on the specific charge off method. The percentage method for additions to the tax bad debt reserve was used prior to the fiscal year ended September 30, 1997. Under the current tax rules, Banks are required to recapture their accumulated tax bad debt reserve, except for the portion that was established prior to 1988, the “base-year.” The recapture of the excess reserve was completed over a six-year phase-in-period that began with the fiscal year ended September 30, 1999. A deferred income tax liability is required to the extent the tax bad debt reserve exceeds the 1988 base year amount. Retained earnings include approximately $3.7 million representing such bad debt reserve for which no deferred taxes have been provided. Distributing the Bank’s capital in the form of stock redemptions caused the Bank to recapture a significant amount of its bad debt reserve prior to the phase-in period.

Derivative Instruments

The Bank regularly enters into commitments to originate and sell loans held for sale. Certain commitments are considered derivative instruments under GAAP, which requires the Bank to recognize all derivative instruments in the balance sheet and to measure those instruments at fair value. As of September 30, 2013 and 2012, the fair value of loan related commitments resulted in a net asset of $1.0 million and $4.1 million, respectively.

Revenue Recognition

Interest income, loan servicing fees, customer service fees and charges and ancillary income related to the Bank’s deposits and lending activities are accrued as earned.

Earnings Per Share

Basic earnings per share is computed based upon the weighted-average common shares outstanding during the year. Diluted earnings per share is computed using the weighted average common shares and all potential dilutive common shares outstanding during the year. Dilutive securities consist entirely of stock options granted to employees as incentive stock options under Section 442A of the Internal Revenue Code as amended.

The computations of basic and diluted earnings (loss) per share are presented in the following table. Dollar amounts are expressed in thousands, except per share data.

At September 30, 2013 and 2012, options to purchase 41,138 and 47,538 shares of the Company’s stock were outstanding. These options were not included in the calculation of diluted earnings (loss) per share because the option exercise price was greater than the average market price of the common shares for the period, thus making the options anti-dilutive.

Recently Issued Accounting Standards

In April 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-02, which clarifies the guidance on how creditors evaluate whether a restructuring of debt qualifies as a TDR. Examples of restructurings include an extension of a loan’s maturity date, a reduction in the interest rate, forgiveness of a debt’s face amount and/or accrued interest, and a deferral or decrease in payments for a period of time. The amendments clarify the definition of a TDR in ASC 310-40, which provides that a debt restructuring is considered a TDR if the creditor, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider. The framework for evaluating a restructuring requires that a creditor determine if both of the following conditions are met: 1) the borrower is experiencing financial difficulties, and 2) the restructuring includes a concession by the creditor to the borrower. For public companies, this standard was effective for the first interim or annual period beginning on or after June 15, 2011. The Company early adopted the ASU in its second fiscal quarter, as permitted by the standard. As a result of adopting the amendments in ASU 2011-02, the Company reassessed all restructurings that occurred on or after October 1, 2010, the beginning of the prior fiscal year, for identification as TDRs. The Company identified as TDRs certain receivables for which the allowance for credit losses had previously been measured under a general allowance for credit losses methodology. Upon identifying those receivables as TDRs, the Company identified them as impaired under the guidance in ASC 310-10-35. The amendments in ASU 2011-02 require prospective application of impairment measured in accordance with the guidance of ASC 310-10-35 for the receivables that are newly identified as impaired. The early adoption of the ASU resulted in a significant increase in the number of loans within its construction and development portfolios that are considered TDRs and had a substantially material impact on the Company’s financial statements for the period ended March 31, 2011. At March 31, 2011, the period of adoption, the recorded investment in receivables for which the allowance for credit losses was previously measured under a general allowance for credit losses methodology and are now impaired under ASC 310-10-35 was $28.1 million, and the resulting allowance for credit losses associated with those receivables, on the basis of a current evaluation of loss, was $8.0 million. In addition, the Company identified loans with a recorded investment of $6.7 million which were previously deemed impaired under the guidance in ASC 310-10-35, but were not considered TDRs. As a result of adopting the amendments in ASU 2011-02, these loans were identified as TDRs and the resulting increase in the allowance for credit losses associated with those receivables, on the basis of a current evaluation of loss, was $3.3 million. This increase in estimated loss was due to the Company’s adoption of a change in methodology for valuing its real estate development portfolio, given the current adverse economic environment, during the quarter ended March 31, 2011.

In December 2011, the FASB issued ASU No. 2011-11, which requires an entity to disclose both gross information and net information about instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting agreement. This additional disclosure is intended to provide greater transparency of the effect or potential effect of rights of offset associated with certain financial instruments and derivative instruments. This standard is effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. The amendments within this update are to be applied retrospectively for all comparative periods presented. Management does not anticipate that that this standard will have a material impact on the Company’s consolidated financial statements.

In January 2013, the FASB issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, which clarifies the scope of the requirements ASU 2011-11. This standard is effective for fiscal years beginning on or after January 1, 2013. The amendments within this update are to be applied retrospectively for all comparative periods presented. Management does not anticipate that that this standard will have a material impact on the Company’s consolidated financial statements.

In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the transparency of reporting reclassification out of accumulated other comprehensive income. The new standard is effective for fiscal years beginning after December 15, 2012, including interim periods within those years. The amendments should be prospectively applied. The amendments do not change the current requirement for reporting net income or other comprehensive income. The amendments require an organization to present on the face of the financial statements, or in the footnotes, the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income if the item reclassified is required to be reclassified to net income in its entirety in the same reporting period. Additionally, for other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required to provide additional detail about those amounts. Management does not believe that the adoption of this standard will have a material impact on the Company’s consolidated financial statements.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses during the reported periods. Estimates were used to establish loss reserves for both loans and foreclosed assets, accruals for loan recourse provisions, and fair values of financial instruments, among other items. Actual results could differ from those estimates.

Reclassifications

Certain amounts for 2012 and 2011 have been reclassified to conform to the current year presentation.

	During the year ended September 30, 2013, the Bank recognized a gain of $295,000 and a loss of $38,000 on the sale of two mortgage backed securities which were classified as held to maturity. The securities had a combined amortized cost of $10.5 million at the time of sale. During fiscal 2012, the Bank recognized a loss of $32,000 on the sale of a mortgage backed security which was classified as held to maturity. The security had an amortized cost of $891,000 at the time of sale. The decision was made to sell these securities after it was determined that there was significant deterioration in the issuer’s creditworthiness. All dispositions of mortgage-backed securities held to maturity during fiscal 2011 were the result of maturities.

	The following tables present a summary of the fair value and gross unrealized losses of those mortgage-backed securities held to maturity which had unrealized losses at September 30, 2013. Dollar amounts are expressed in thousands.

	Management monitors the securities portfolio for impairment on an ongoing basis by evaluating market conditions and other relevant information, including external credit ratings, to determine whether or not a decline in value is other-than-temporary. When the fair value of a security is less than its amortized cost, an other-than-temporary impairment is considered to have occurred if the present value of expected cash flows is not sufficient to recover the entire amortized cost, or if the Company intends to, or will be required to, sell the security prior to the recovery of its amortized cost. The unrealized losses at September 30, 2013, are primarily the result of changes in market yields from the time of purchase. Management generally views changes in fair value caused by changes in interest rates as temporary. In addition, all scheduled payments for securities with unrealized losses at September 30, 2013, have been made, and it is anticipated that the entire principal balance of such securities will be collected.

	The scheduled maturities of mortgage-backed securities held to maturity at September 30, 2013, are presented in the following table. Dollar amounts are expressed in thousands.

	The Bank has traditionally concentrated its lending activities on mortgage loans secured by residential and business property and, to a lesser extent, development lending. Residential mortgage loans have either long-term fixed or adjustable rates. The Bank also has a portfolio of mortgage loans that are secured by multifamily, construction, development, and commercial real estate properties. The remaining part of North American’s loan portfolio consists of non-mortgage commercial and installment loans.

	The following table presents the Bank’s total loans receivable at September 30. Dollar amounts are expressed in thousands.

	Included in the loans receivable balances are participating interests in mortgage loans and wholly owned mortgage loans serviced by other institutions of approximately $976,000 and $4.1 million at September 30, 2013 and 2012, respectively.

	Whole loans and participations serviced for others were approximately $24.4 million and $27.3 million at September 30, 2013 and 2012, respectively. Loans serviced for others are not included in the accompanying consolidated balance sheets.

	First mortgage loans were pledged to secure FHLB advances in the amount of approximately $522.1 million and $508.9 million at September 30, 2013 and 2012, respectively.



	Aggregate loans to executive officers, directors and their associates, including companies in which they have partial ownership interest, did not exceed 5% of equity as of September 30, 2013 and 2012. Such loans were made under terms and conditions substantially the same as loans made to parties not affiliated with the Bank.

	Proceeds from the sale of loans receivable held for sale during fiscal 2013, 2012 and 2011, were $1,977.7 million, $1,850.0 million, and $1,693.0 million, respectively. In fiscal 2013, the Bank realized gross gains of $62.2 million and $30,000 of gross losses. In fiscal 2012, the Bank realized gross gains of $48.8 million and $2,000 of gross losses. In fiscal 2011, the Bank realized gross gains of $29.4 million and gross losses of $140,000 on those sales

	Lending Practices and Underwriting Standards

	Residential real estate loans - The Bank offers a range of residential loan programs, including programs offering loans guaranteed by the Veterans Administration (“VA”) and loans insured by the Federal Housing Administration (“FHA”). The Bank’s residential loans come from several sources. The loans that the Bank originates are generally a result of direct solicitations of real estate brokers, builders, developers, or potential borrowers via the internet. North American periodically purchases real estate loans from other financial institutions or mortgage bankers.

	The Bank’s residential real estate loan underwriters are grouped into three different levels, based upon each underwriter’s experience and proficiency. Underwriters within each level are authorized to approve loans up to prescribed dollar amounts. Any loan over $1 million must also be approved by either the Board Chairman, CEO or EVP/Residential Lending. Conventional residential real estate loans are underwritten using FNMA’s Desktop Underwriter or FHLMC’s Loan Prospector automated underwriting systems, which analyze credit history, employment and income information, qualifying ratios, asset reserves, and loan-to-value ratios. If a loan does not meet the automated underwriting standards, it is underwritten manually. Full documentation to support each applicant’s credit history, income, and sufficient funds for closing is required on all loans. An appraisal report, performed in conformity with the Uniform Standards of Professional Appraisers Practice by an approved outside licensed appraiser, is required for substantially all loans. Typically, the Bank requires borrowers to purchase private mortgage insurance when the loan-to-value ratio exceeds 80%.

	NASB originates Adjustable Rate Mortgages (ARMs), which fully amortize and typically have initial rates that are fixed for one to seven years before becoming adjustable. Such loans are underwritten based on the initial interest rate and the borrower’s ability to repay based on the maximum first adjustment rate. Each underwriting decision takes into account the type of loan and the borrower’s ability to pay at higher rates. While lifetime rate caps are taken into consideration, qualifying ratios may not be calculated at this level due to an extended number of years required to reach the fully-indexed rate. NASB does not originate any hybrid loans, such as payment option ARMs, nor does the Bank originate any subprime loans, generally defined as high risk or loans of substantially impaired quality.

	At the time a potential borrower applies for a residential mortgage loan, it is designated as either a portfolio loan, which is held for investment and carried at amortized cost, or a loan held-for-sale in the secondary market and carried at fair value. All the loans on single family property that the Bank holds for sale conform to secondary market underwriting criteria established by various institutional investors. All loans originated, whether held for sale or held for investment, conform to internal underwriting guidelines, which consider, among other things, a property’s value and the borrower’s ability to repay the loan.

	Construction and development loans - Construction and land development loans are made primarily to builders/developers, who construct properties for resale. The Bank’s requirements for a construction loan are similar to those of a mortgage on an existing residence. In addition, the borrower must submit accurate plans, specifications, and cost projections of the property to be constructed. All construction and development loans are manually underwritten using NASB’s internal underwriting standards. All construction and development loans require two approvals, from either the Board Chairman, CEO, or SVP/Construction Lending. Prior approval is required from the Bank’s Board of Directors for newly originated construction and development loans with a proposed balance of $1.0 million or greater. The bank has adopted internal loan-to-value limits consistent with regulations, which are 65% for raw land, 75% for land development, and 85% for residential and non-residential construction. An appraisal report performed in conformity with the Uniform Standards of Professional Appraisers Practice by an approved outside licensed appraiser is required on all loans in excess of $250,000. Generally, the Bank will commit to an initial term of 12 to 18 months on construction loans, and an initial term of 24 to 48 months on land acquisition and development loans, with six month renewals thereafter. Interest rates on construction loans typically adjust daily and are tied to a predetermined index. NASB’s staff regularly performs inspections of each property during its construction phase to help ensure adequate progress is achieved before making scheduled loan disbursements.



	When construction and development loans mature, the Bank typically considers extensions for short, six-month term periods. This allows the Bank to more frequently evaluate the loan, including creditworthiness and current market conditions and, if management believes it’s in the best interest of the Company, to modify the terms accordingly. This portfolio consists primarily of assets with rates tied to the prime rate and, in most cases, the conditions for loan renewal include an interest rate “floor” in accordance with the market conditions that exist at the time of renewal.

	During the year ended September 30, 2013, the Bank renewed seventy-six loans within its construction and land development portfolio due to slower home and lot sales in the current economic environment. Such extensions were accounted for as Troubled Debt Restructurings (“TDRs”) if the restructuring was related to the borrower’s financial difficulty, and if the Bank made concessions that it would not otherwise consider. In order to determine whether or not a renewal should be accounted for as a TDR, management reviewed the borrower’s current financial information, including an analysis of income and liquidity in relation to debt service requirements. The large majority of these modifications did not result in a reduction in the contractual interest rate or a write-off of the principal balance (although the Bank does commonly require the borrower to make a principal reduction at renewal).

Commercial real estate loans - The Bank purchases and originates several different types of commercial real estate loans. Permanent multifamily mortgage loans on properties of 5 to 36 dwelling units have a 50% risk-weight for risk-based capital requirements if they have an initial loan-to-value ratio of not more than 80% and if their annual average occupancy rate exceeds 80%. All other performing commercial real estate loans have 100% risk-weights.

The Bank’s commercial real estate loans are secured primarily by multi-family and nonresidential properties. Such loans are manually underwritten using NASB’s internal underwriting standards, which evaluate the sources of repayment, including the ability of income producing property to generate sufficient cash flow to service the debt, the capacity of the borrower or guarantors to cover any shortfalls in operating income, and, as a last resort, the ability to liquidate the collateral in such a manner as to completely protect the Bank’s investment. All commercial real estate loans require two approvals, from either the Board Chairman, CEO, or EVP/Chief Lending Officer. Prior approval is required from the Bank’s Board of Directors for newly originated commercial loans with a proposed balance of $1.0 million or greater. Typically, loan-to-value ratios do not exceed 80%; however, exceptions may be made when it is determined that the safety of the loan is not compromised, and the rationale for exceeding this limit is clearly documented. An appraisal report performed in conformity with the Uniform Standards of Professional Appraisers Practice by an approved outside licensed appraiser is required on all loans in excess of $250,000. Interest rates on commercial loans may be either fixed or tied to a predetermined index and adjusted daily.

The Bank typically obtains full personal guarantees from the primary individuals involved in the transaction. Guarantor financial statements and tax returns are reviewed annually to determine their continuing ability to perform under such guarantees. The Bank typically pursues repayment from guarantors when the primary source of repayment is not sufficient to service the debt. However, the Bank may decide not to pursue a guarantor if, given the guarantor’s financial condition, it is likely that the estimated legal fees would exceed the probable amount of any recovery. Although the Bank does not typically release guarantors from their obligation, the Bank may decide to delay the decision to pursue civil enforcement of a deficiency judgment.

At least once during each calendar year, a review is prepared for each borrower relationship in excess of $5 million and for each individual loan over $1 million. Collateral inspections are obtained on an annual basis for each loan over $1 million, and on a triennial basis for each loan between $500,000 and $1 million. Financial information, such as tax returns, is requested annually for all commercial real estate loans over $500,000, which is consistent with industry practice, and the Bank believes it has sufficient monitoring procedures in place to identify potential problem loans. A loan is deemed impaired when, based on current information and events, it is probable that a creditor will be unable to collect all amounts due in accordance with the contractual terms of the loan agreement. Any loans deemed impaired, regardless of their balance, are reviewed by management at the time of the impairment determination, and monitored on a quarterly basis thereafter, including calculation of specific valuation allowances, if applicable.

Installment Loans - These loans consist primarily of loans on savings accounts and consumer lines of credit that are secured by a customer’s equity in their primary residence.



Allowance for Loan Losses

The Allowance for Loan and Lease Losses (“ALLL”) recognizes the inherent risks associated with lending activities for individually identified problem assets as well as the entire homogenous and non-homogenous loan portfolios. ALLLs are established by charges to the provision for loan losses and carried as contra assets. Management analyzes the adequacy of the allowance on a quarterly basis and appropriate provisions are made to maintain the ALLLs at adequate levels. At any given time, the ALLL should be sufficient to absorb at least all estimated credit losses on outstanding balances over the next twelve months. While management uses information currently available to determine these allowances, they can fluctuate based on changes in economic conditions and changes in the information available to management. Also, regulatory agencies review the Bank’s allowances for loan loss as part of their examination, and they may require the Bank to recognize additional loss provisions, within their regulatory filings, based on the information available at the time of their examinations.

The ALLL is determined based upon two components. The first is made up of specific reserves for loans which have been deemed impaired in accordance with GAAP. The second component is made up of general reserves for loans that are not impaired. A loan becomes impaired when management believes it will be unable to collect all principal and interest due according to the contractual terms of the loan. Once a loan has been deemed impaired, the impairment must be measured by comparing the recorded investment in the loan to the present value of the estimated future cash flows discounted at the loan’s effective rate, or to the fair value of the loan based on the loan’s observable market price, or to the fair value of the collateral if the loan is collateral dependent. Prior to the quarter ended March 31, 2012, the Bank recorded a specific allowance equal to the amount of measured impairment.

In July 2011, the Office of Thrift Supervision (“OTS”) merged with and into the Office of the Comptroller of the Currency (“OCC”), and the OCC became the Bank’s primary regulator. Beginning with the quarter ended March 31, 2012, the Bank was required to file a Consolidated Report of Condition and Income (“Call Report”) instead of the previously required Thrift Financial Report (“TFR”). With the adoption of the Call Report, the Bank was required to discontinue using specific valuation allowances on loans deemed impaired. The TFR had allowed any measured impairments to be carried as specific valuation allowances, whereas the Call Report required any measured impairments that are deemed “confirmed losses” to be charged-off and netted from their respective loan balances. For impaired loans that are collateral dependent, a “confirmed loss” is generally the amount by which the loan’s recorded investment exceeds the fair value of its collateral. If a loan is considered uncollectible, the entire balance is deemed a “confirmed loss” and is fully charged-off. During the quarter ended March 31, 2012, the Bank charged-off against ALLL the aggregate “confirmed losses” of $23.3 million that were carried as specific valuation allowances in prior periods, and netted them against their respective loan balances for reporting purposes. This change had no impact on net loans receivable as presented in the consolidated balance sheet. In addition, this change did not materially impact the analysis of ALLL, which is described in more detail in the following paragraph, as specific valuation allowances were previously considered in the determination of historical loss ratios.

Loans that are not impaired are evaluated based upon the Bank’s historical loss experience, as well as various subjective factors, to estimate potential unidentified losses within the various loan portfolios. These loans are categorized into pools based upon certain characteristics such as loan type, collateral type and repayment source. In addition to analyzing historical losses, the Bank also evaluates the following subjective factors for each loan pool to estimate future losses: changes in lending policies and procedures, changes in economic and business conditions, changes in the nature and volume of the portfolio, changes in management and other relevant staff, changes in the volume and severity of past due loans, changes in the quality of the Bank’s loan review system, changes in the value of the underlying collateral for collateral dependent loans, changes in the level of lending concentrations, and changes in other external factors such as competition and legal and regulatory requirements. Historical loss ratios are adjusted accordingly, based upon the effect that the subjective factors have in estimated future losses. These adjusted ratios are applied to the balances of the loan pools to determine the adequacy of the ALLL each quarter. For purposes of calculating historical loss ratios, specific valuation allowances established prior to March 31, 2012, are considered charge-offs during the periods in which they are established.

The Bank does not routinely obtain updated appraisals for their collateral dependent loans that are not adversely classified. However, when analyzing the adequacy of its allowance for loan losses, the Bank considers potential changes in the value of the underlying collateral for such loans as one of the subjective factors used to estimate future losses in the various loan pools.

Classified Assets, Delinquencies, and Non-accrual Loans

Classified assets - In accordance with the Bank’s asset classification system, problem assets are classified with risk ratings of either “substandard,” “doubtful,” or “loss.” An asset is considered substandard if it is inadequately protected by the borrower’s ability to repay, or the value of collateral. Substandard assets include those characterized by a possibility that the institution will sustain some loss if the deficiencies are not corrected. Assets classified as doubtful have the same weaknesses of 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. Assets classified as loss are considered uncollectible and of little value. Prior to the quarter ended March 31, 2012, the Bank established a specific valuation allowance for such assets. In conjunction with the adoption of the Call Report during the quarter ended March 31, 2012, such assets are charged-off against the ALLL at the time they are deemed to be a “confirmed loss.”

In addition to the risk rating categories for problem assets noted above, loans may be assigned a risk rating of “pass,” “pass-watch,” or “special mention.” The pass category includes loans with borrowers and/or collateral that is of average quality or better. Loans in this category are considered average risk and satisfactory repayment is expected. Assets classified as pass-watch are those in which the borrower has the capacity to perform according to the terms and repayment is expected. However, one or more elements of uncertainty exist. Assets classified as special mention have a potential weakness that deserves management’s close attention. If left undetected, the potential weakness may result in deterioration of repayment prospects.



Each quarter, management reviews the problem loans in its portfolio to determine whether changes to the asset classifications or allowances are needed. The following table presents the credit risk profile of the Company’s loan portfolio based on risk rating category as of September 30, 2013. Dollar amounts are expressed in thousands.

When a loan becomes 90 days past due, or when full payment of interest and principal is not expected, the Bank stops accruing interest and establishes a reserve for the unpaid interest accrued-to-date. In some instances, a loan may become 90 days past due if it has exceeded its maturity date but the Bank and borrower are still negotiating the terms of an extension agreement. In those instances, the Bank typically continues to accrue interest, provided the borrower has continued making interest payments after the maturity date and full payment of interest and principal is expected.

The following table presents the Company’s loans meeting the regulatory definition of nonaccrual, which includes certain loans that are current and paying as agreed. This table does not include purchased impaired loans or troubled debt restructurings that are performing. Dollar amounts are expressed in thousands.

As of September 30, 2013, $20.2 million (63.8%) of the loans classified as nonaccrual were current and paying as agreed.

Gross interest income would have increased by $675,000, $1.2 million and $2.8 million for the years ended September 30, 2013, 2012 and 2011, respectively, if the nonaccrual loans had been performing.

During the quarter ended March 31, 2012, the Company’s nonaccrual loans increased $41.4 million. This increase resulted from management’s decision to move certain impaired collateral dependent loans secured by land development, commercial real estate, and residential rental properties to nonaccrual, even though the majority of such loans were current and paying in accordance with their contractual terms. Due to the continued deterioration in the real estate markets, management determined that the full collection of principal and interest was uncertain. In accordance with GAAP, these loans were charged-down to the fair value of their underlying collateral, and therefore, the recorded investment in the loan is deemed fully collectable at September 30, 2013. Interest income is recognized on a cash-basis as payments are received. The majority of these loans currently remain in non-accrual status; however, loans with a carrying value of $12.6 million at September 30, 2013, were returned to a performing status during the fiscal year, based upon improvement in the real estate markets and the borrower’s financial condition.



A loan becomes impaired when management believes it will be unable to collect all principal and interest due according to the contractual terms of the loan. A restructuring of debt is considered a TDR if, because of a debtor’s financial difficulty, a creditor grants concessions that it would not otherwise consider. Loans modified in troubled debt restructurings are also considered impaired. Concessions granted in a TDR could include a reduction in interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. Once a loan has been deemed impaired, the impairment must be measured by comparing the recorded investment in the loan to the present value of the estimated future cash flows discounted at the loan’s effective rate, or to the fair value of the loan based on the loan’s observable market price, or to the fair value of the collateral if the loan is collateral dependent. Unless the loan is performing prior to the restructure, TDRs are placed in non-accrual status at the time of restructuring and may only be returned to performing status after the borrower demonstrates sustained repayment performance for a reasonable period, generally six months.

The Bank issues various representations and warranties and standard recourse provisions associated with the sale of loans to outside investors, which may require the Bank to repurchase a loan that defaults or has identified defects, or to indemnify the investor in the event of a material breach of contractual representations and warranties. Such provisions related to early payoff and early payment default typically expire 90 to 180 days after purchase. Repurchase obligations related to fraud or misrepresentation remain outstanding during the life of the loan. During the fiscal years ended September 30, 2013, 2012 and 2011, the Bank established reserves related to various representations and warranties that reflect management’s estimate of losses based on various factors. Such factors include estimated level of defects, historical repurchase demand, success rate in avoiding claims, and projected loss severity. Reserves are established at the time loans are sold, and updated during their estimated life. During the last eight fiscal years, the Bank sold loans with recourse totaling $11.4 billion. It is management’s estimate that the total recourse liability associated with such loans was $2.6 million and $5.3 million at September 30, 2013 and 2012, respectively. The reserve for such losses is included in “Accrued expenses and other liabilities” in the Bank’s consolidated financial statements.

During the fiscal years ended September 30, 2013, 2012 and 2011, the Bank experienced increased losses resulting from investor charges for loans with defects, repurchased loans, and early prepayment and early default penalties. This trend accelerated during the last half of the fiscal 2009 and has continued through fiscal 2013. The Company repurchased or incurred losses on loans with balances of $13.6 million, $9.9 million, and $11.6 million during fiscal year 2013, 2012 and 2011, respectively. Total losses incurred on these loans were $923,000, $290,000 and $1.4 million during fiscal year 2013, 2012 and 2011, respectively. Repurchased loans are recorded at fair value and evaluated for impairment in accordance with GAAP. In addition, during fiscal 2013, the Bank negotiated global settlements with two investors, which release the Bank from further liability for all known and unknown claims, subject to certain exceptions for fraud committed by Bank employees.

The following table presents the activity in the reserve related to representations and warranties for the year ended September 30. Dollar amounts are expressed in thousands.




		2013				2012				2011
Balance at beginning of year		$	5,267				3,535				2,157
Additions to reserve			1,433				2,022				2,754

Balance at end of year		$	2,637				5,267				3,535

The increase in repurchase loans and settlement losses originated primarily due to weak economic conditions, as investors made increased demands associated with the higher level of loans in default. The Bank has had some success in avoiding claims. During fiscal 2013, the Bank successfully cleared twenty-five out of fifty, or fifty percent, of the repurchase requests that it received. During fiscal 2012, the Bank successfully cleared twenty-nine out of seventy-one, or forty-one percent, of the repurchase requests that it received. This success rate is one indicator of future losses, but it is affected by various factors such as the type of claim and the investor making the claim. If economic conditions, particularly the housing market, decline in future periods, it is management’s opinion that the Bank may experience increased loss severity on repurchased loans, resulting in further additions to the reserve. However, the Bank began to tighten underwriting standards in mid 2008, so it expects a lower level of repurchase requests for loans originated thereafter. Management believes that the current reserve is adequate to cover the expected settlement amount on loans that remain outstanding and are not covered under the aforementioned global settlements.

	(7) FORECLOSED ASSETS HELD FOR SALE

	The carrying value of real estate owned and other repossessed property was $11.3 million and $17.0 million at September 30, 2013 and 2012, respectively



	Foreclosed assets held for sale are initially recorded at fair value as of the date of foreclosure less any estimated selling costs (the “new basis”) and are subsequently carried at the lower of the new basis or fair value less selling costs on the current measurement date. When foreclosed assets are acquired, any excess of the loan balance over the new basis of the foreclosed asset is charged to the allowance for loan losses. Subsequent adjustments for estimated losses are charged to operations when the fair value declines to an amount less than the carrying value. Costs and expenses related to major additions and improvements are capitalized, while maintenance and repairs that do not improve or extend the lives of the respective assets are expensed. Applicable gains and losses on the sale of real estate owned are realized when the asset is disposed of, depending on the adequacy of the down payment and other requirements.

	With the adoption of the Call Report during the quarter ended March 31, 2012, the Bank was required to begin following regulatory guidance related to the Call Report requirements. One such requirement resulted in a change in the treatment of specific loss reserves for foreclosed assets held for sale. Previous Thrift Financial Report guidance allowed banks to reduce an asset’s carrying value through a specific allowance when the fair value declined to an amount less than its carrying value. Call Report guidance requires that the carrying value of foreclosed assets held for sale be written down to fair value through a charge to earnings. During the quarter ended March 31, 2012, the Bank charged-off the previously established specific allowances on such assets of $9.4 million. This change had no impact on net foreclosed assets held for sale as presented in the consolidated balance sheet.

	The allowance for losses on real estate owned includes the following activity for the years ended September 30. Dollar amounts are expressed in thousands.

	In addition to the provision for loss noted above, the Company incurred net expenses of $1.5 million, $1.7 million, and $1.9 million related to foreclosed assets held for sale during the fiscal years ended September 30, 2013, 2012 and 2011, respectively.

Equity Method Investments And Joint Ventures [Abstract]	'
INVESTMENT IN LLCs	'
	(9) INVESTMENT IN LLCs
	The Company is a partner in two limited liability companies, Central Platte Holdings LLC (“Central Platte”) and NBH, LLC (“NBH”), which were formed for the purpose of purchasing and developing vacant land in Platte County, Missouri. These investments are accounted for using the equity method of accounting.
	The Company’s investment in Central Platte consists of a 50% ownership interest in an entity that develops land for residential real estate sales. Sales of lots have not met previous expectations and, as a result, the Company evaluated its investment for impairment, in accordance with ASC 323-10-35-32, which provides guidance related to a loss in value of an equity method investment. The Company utilizes a multi-faceted approach to measure the potential impairment. The internal model utilizes the following valuation methods: 1) liquidation or appraised values determined by an independent third party appraisal; 2) an on-going business, or discounted cash flows method wherein the cash flows are derived from the sale of fully-developed lots, the development and sale of partially-developed lots, the operation of the homeowner’s association, and the value of raw land obtained from an independent third party appraiser; and 3) another on-going business method, which utilizes the same inputs as method 2, but presumes that cash flows will first be generated from the sale of raw ground and then from the sale of fully-developed and partially-developed lots and the operation of the homeowner’s association. The internal model also includes method 4, an on-going business method wherein the cash flows are derived from the sale of fully-developed lots, the development and sale of partially-developed lots, the operation of the homeowner’s association, and the development and sale of lots from the property that is currently raw land. However, management does not feel the results from this method provide a reliable indication of value because the time to “build-out” the development exceeds 18 years. Because of this unreliability, the results from method 4 are given a zero weighting in the final impairment analysis. The significant inputs include raw land values, absorption rates of lot sales, and a market discount rate. Management believes this multi-faceted approach is reasonable given the highly subjective nature of the assumptions and the differences in valuation techniques that are utilized within each approach (e.g., order of distribution of assets upon potential liquidation). It is management’s opinion that no one valuation method within the model is preferable to the other and that no one method is more likely to occur than the other. Therefore, the final estimate of value is determined by assigning an equal weight to the values derived from each of the first three methods described above.

	As a result of this analysis, the Company determined that its investment in Central Platte was materially impaired and recorded an impairment charge of $2.0 million ($1.2 million, net of tax) during the year ended September 30, 2010. During the quarter ended March 31, 2012, list prices of fully-developed lots in Central Platte’s residential development were reduced. The Company incorporated these lower prices into its internal valuation model, which resulted in an additional impairment charge of $200,000 ($123,000, net of tax) during the quarter ended March 31, 2012. No other events have occurred that would indicate any additional impairment of the Company’s investment in Central Platte.
	The following table displays the results derived from the Company’s internal valuation model at September 30, 2013, and the carrying value of its investment in Central Platte at September 30, 2013. Dollar amounts are expressed in thousands.

	Average of methods 1, 2, and 3	$	16,651

	Carrying value of investment in Central Platte Holdings, LLC	$	15,132

	The Company’s investment in NBH consists of a 50% ownership interest in an entity that holds raw land, which is currently zoned as agricultural. The general managers intend to rezone this property for commercial and/or residential development. The raw land was purchased in 2002. The Company accounts for its investment in NBH under the equity method. Due to the overall economic conditions surrounding real estate, the Company evaluated its investment for impairment in accordance with ASC 323-10-35-32, which provides guidance related to a loss in value of an equity method investment. Potential impairment was measured based on liquidation or appraised values determined by an independent third party appraisal. As a result of this analysis, the Company determined that its investment in NBH was materially impaired and recorded an impairment charge of $1.1 million ($693,000, net of tax) during the year ended September 30, 2010. The results of this analysis as of September 30, 2013, did not indicate any additional impairment of the Company’s investment in NBH. The carrying value of the Company’s investment in NBH was $1.4 million at September 30, 2013.

	On December 13, 2006, the Company, through its wholly owned statutory trust, NASB Preferred Trust I (the “Trust”), issued $25 million of pooled Trust Preferred Securities. The Trust used the proceeds from the offering to purchase a like amount of the Company’s subordinated debentures. The debentures, which have a variable rate of 1.65% over the 3-month LIBOR and a 30-year term, are the sole assets of the Trust. In exchange for the capital contributions made to the Trust by the Company upon formation, the Company owns all the common securities of the Trust.

	In accordance with Financial Accounting Standards Board ASC 810-10, the Trust qualifies as a special purpose entity that is not required to be consolidated in the financial statements of the Company. The $25.0 million Trust Preferred Securities issued by the Trust will remain on the records of the Trust. The Trust Preferred Securities are included in Tier I capital for regulatory capital purposes.

	The Trust Preferred Securities have a variable interest rate of 1.65% over the 3-month LIBOR, and are mandatorily redeemable upon the 30-year term of the debentures, or upon earlier redemption as provided in the Indenture. The debentures are callable, in whole or in part, after five years of the issuance date. The Company did not incur a placement or annual trustee fee related to the issuance. The securities are subordinate to all other debt of the Company and interest may be deferred up to five years.

	On July 11, 2012, the Company notified security holders that it was exercising its right to defer the payment of interest on its Trust Preferred Securities for a period of up to five years. Accrued but unpaid interest on such securities was $729,000 and $225,000 at September 30, 2013 and 2012, respectively.

REGULATORY CAPITAL REQUIREMENTS	'
	(15) REGULATORY CAPITAL REQUIREMENTS
	The Bank is subject to various regulatory capital requirements as administered by Federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by the regulators that, if undertaken, could have a direct material effect on the Bank’s financial statements. Under the capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by regulators about components, risk weightings, and other factors.
	Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum capital amounts and ratios (set forth in the table below). The Bank’s primary regulatory agency requires that the Bank maintain minimum ratios of tangible capital (as defined in the regulations) of 1.5%, core capital (as defined) of 4%, and total risk-based capital (as defined) of 8%. The Bank is also subject to prompt corrective action capital requirement regulations set forth by the FDIC. The FDIC requires the Bank to maintain a minimum of Tier 1, total and core capital (as defined) to risk-weighted assets (as defined), and of core capital (as defined) to adjusted tangible assets (as defined). Management believes that, as of September 30, 2013, the Bank meets all capital adequacy requirements, to which it is subject.
	On May 22, 2012, the Board of Directors of the Bank agreed to a Consent Order with the OCC, which is described more fully in Footnote 25, Regulatory Agreements. Among other items, the Consent Order requires that the Bank maintain a Tier 1 leverage capital ratio equal to or greater than 10% and a risk-based capital ratio equal to or greater than 13%. As of September 30, 2013, the Bank’s actual Tier 1 leverage capital and total risk-based capital ratios were 17.7% and 25.1%, respectively. The existence of individual minimum capital requirements means that the Bank may not be deemed well capitalized.
	The following tables summarize the relationship between the Bank’s capital and regulatory requirements. Dollar amounts are expressed in thousands.

	Substantially all of the Bank’s full-time employees participate in a 401(k) retirement plan (the “Plan”). The Plan is administered by Standard Insurance Company, through which employees can choose from a variety of retail mutual funds to invest their fund contributions. Under the terms of the Plan, the Bank makes monthly contributions for the benefit of each participant in an amount that matches one-half of the participant’s contribution, not to exceed 3% of the participants’ monthly base salary. All contributions made by participants are immediately vested and cannot be forfeited. Contributions made by the Bank, and related earnings thereon, become vested to the participants according to length of service requirements as specified in the Plan. Any forfeited portions of the contributions made by the Bank and the allocated earnings thereon are used to reduce future contribution requirements of the Bank. The Plan may be modified, amended or terminated at the discretion of the Bank.
	The Bank’s contributions to the Plan amounted to $716,000, $645,000, and $523,000 for the years ended September 30, 2013, 2012, and 2011, respectively. These amounts have been included as compensation and fringe benefits expense in the accompanying consolidated statements of operations.

	The Company has identified two principal operating segments for purposes of financial reporting: Banking and Mortgage Banking. These segments were determined based on the Company’s internal financial accounting and reporting processes and are consistent with the information that is used to make operating decisions and to assess the Company’s performance by the Company’s key decision makers.
	The Mortgage Banking segment originates mortgage loans for sale to investors and for the portfolio of the Banking segment. The Banking segment provides a full range of banking services through the Bank’s branch network, exclusive of mortgage loan originations. A portion of the income presented in the Mortgage Banking segment is derived from sales of loans to the Banking segment based on a transfer pricing methodology that is designed to approximate economic reality. The Other and Eliminations segment includes financial information from the parent company plus inter-segment eliminations.

	(19) COMMITMENTS AND CONTINGENCIES
	In the normal course of business, the Bank has entered into financial agreements with off-balance-sheet risk to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and financial guarantees. Those instruments involve, to varying degrees, elements of credit risk, interest rate risk, and liquidity risk, which may exceed the amount recognized in the consolidated financial statements. The contract amounts or notional amounts of those instruments express the extent of involvement the Bank has in particular classes of financial instruments.
	With regard to financial instruments for commitments to extend credit, standby letters of credit, and financial guarantees, the Bank’s exposure to credit loss because of non-performance by another party is represented by the contractual amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.
	As of September 30, 2013, the Bank had outstanding commitments to originate $6.6 million in commercial real estate loans, $181.8 million of fixed rate residential first mortgage loans and $12.4 million of adjustable rate residential first mortgage loans. Commercial real estate loan commitments have approximate average committed rates of 5.0%. Residential mortgage loan commitments have an approximate average committed rate of 4.2% and approximate average fees and discounts of 0.1%. The interest rate commitments on residential loans generally expire 60 days after the commitment date. Interest rate commitments on commercial real estate loans have varying terms to expiration. As of September 30, 2013, the Bank had outstanding commitments related to stand-by letters of credit of $646,000.
	As of September 30, 2012, the Bank had outstanding commitments to originate $361.5 million of fixed rate residential first mortgage loans and $47.1 million of adjustable rate residential first mortgage loans. Such residential mortgage loan commitments have an approximate average committed rate of 3.4% and approximate average fees and discounts of 0.1%. The interest rate commitments on residential loans generally expire 60 days after the commitment date. As of September 30, 2012, the Bank had outstanding commitments related to stand-by letters of credit of $794,000.
	At September 30, 2013 and 2012, the Bank had commitments to sell loans of approximately $177.6 million and $405.2 million, respectively. These instruments contain an element of risk in the event that other parties are unable to meet the terms of such agreements. In such event, the Bank’s loans receivable held for sale would be exposed to market fluctuations. Management does not expect any other party to default on its obligations and, therefore, does not expect to incur any costs due to such possible default.

	The recent protracted economic decline presented financial institutions with unprecedented circumstances and challenges which in some cases resulted in large declines in the fair values of investments and other assets, constraints on liquidity and significant credit quality problems, including severe volatility in the valuation of real estate and other collateral supporting loans. The financial statements have been prepared using values and information currently available to the Company.
	Given the volatility of recent economic conditions, the values of assets and liabilities recorded in the financial statements could change rapidly, resulting in material future adjustments in asset values, the allowance for loan losses, and capital that could negatively impact the Company’s ability to meet regulatory capital requirements and maintain sufficient liquidity.
	The Company’s construction and development loan portfolio includes loans that are in excess of supervisory loan-to-value limits. As of September 30, 2013 and 2012, 5.0% and 14.0% of this portfolio was made up of such loans, respectively.

FAIR VALUE OPTION	'
	(22) FAIR VALUE OPTION
	On October 1, 2008, the Company elected to measure loans held for sale at fair value. This portfolio is made up entirely of mortgage loans held for immediate sale with servicing released. Such loans are sold prior to origination at a contracted price to outside investors on a best-efforts basis (i.e., the loan becomes mandatorily deliverable to the investor only when, and if, it closes) and remain on the Company’s balance sheet for a very short period of time, typically less than one month. It is management’s opinion, given the short-term nature of these loans, that fair value provides a reasonable measure of the economic value of these assets. In addition, carrying such loans at fair value eliminates some measure of volatility created by the timing of sales proceeds from outside investors, which typically occur in the month following origination.
	The aggregate fair value of these loans was $2.1 million and $3.8 million greater than the aggregate unpaid principal balance at September 30, 2013 and 2012, respectively. Interest income on loans held for sale is included in interest on loans receivable in the accompanying statements of income.

	The Company has commitments outstanding to extend credit that have not closed prior to the end of the period. As the Company enters into commitments to originate loans, it also enters into commitments to sell the loans in the secondary market on a “best-efforts” basis. Such commitments to originate loans held for sale are considered derivative instruments in accordance with GAAP, which requires the Company to recognize all derivative instruments in the balance sheet and to measure those instruments at fair value. As a result of marking to market commitments to originate loans, the Company recorded a decrease in other assets of $1.2 million, a decrease in other liabilities of $299,000, and a decrease in other income of $873,000 for the year ended September 30, 2013. The Company recorded an increase in other assets of $1.3 million, a decrease in other liabilities of $382,000, and an increase in other income of $1.7 million for the year ended September 30, 2012.
	Additionally, the Company has commitments to sell loans that have closed prior to the end of the period.

FAIR VALUE MEASUREMENTS	'
	(24) FAIR VALUE MEASUREMENTS
	Fair value is defined as the price that would likely be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. GAAP identifies three primary measurement techniques: the market approach, the income approach, and the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The income approach uses valuations or techniques to convert future amounts, such as cash flows or earnings, to a single present amount. The cost approach is based on the amount that currently would be required to replace the service capability of an asset.
	GAAP establishes a fair value hierarchy and prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to observable inputs such as quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The maximization of observable inputs and the minimization of the use of unobservable inputs are required. Classification within the fair value hierarchy is based upon the objectivity of the inputs that are significant to the valuation of an asset or liability as of the measurement date. The three levels within the fair value hierarchy are characterized as follows:
		•		Level 1 – Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
		•		Level 2 – Inputs other than quoted prices included with Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include: quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability; and inputs that are derived principally from, or corroborated by, observable market data by correlation or other means.
		•		Level 3 – Unobservable inputs for the asset or liability for which there is little, if any, market activity for the asset or liability at the measurement date. Unobservable inputs reflect the Company’s own assumptions about what market participants would use to price the asset or liability. These inputs may include internally developed pricing models, discounted cash flow methodologies, as well as instruments for which the fair value determination requires significant management judgment.
	The Company measures certain financial assets and liabilities at fair value in accordance with GAAP. These measurements involve various valuation techniques and assume that the transactions would occur between market participants in the most advantageous market for the Company.
	The following is a summary of valuation techniques utilized by the Company for its significant financial assets and liabilities measured at fair value on a recurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy:
	Available for sale securities
	Securities available for sale consist of corporate debt, trust preferred, U. S. government sponsored agency, and municipal securities. Such securities are valued using market prices in an active market, if available. This measurement is classified as Level 1 within the hierarchy. Less frequently traded securities are valued using industry standard models which utilize various assumptions such as historical prices of the same or similar securities, and observation of market prices of securities of the same issuer, market prices of same-sector issuers, and fixed income indexes. Substantially all of these assumptions are observable in the marketplace or can be derived from observable data. These measurements are classified as Level 2 within the hierarchy.
	Mortgage-backed securities available for sale, which consist of agency pass-through and participation certificates issued by GNMA, FNMA, and FHLMC, were valued by using industry standard models which utilize various inputs and assumptions such as historical prices of benchmark securities, prepayment estimates, loan type, and year of origination. Substantially all of these assumptions are observable in the marketplace or can be derived from observable data. These measurements are classified as Level 2 within the hierarchy.
	Loans held for sale
	Loans held for sale are valued using quoted market prices for loans with similar characteristics. This measurement is classified as Level 2 within the hierarchy.
	Commitments to Originate Loans and Forward Sales Commitments
	Commitments to originate loans and forward sales commitments are valued using a valuation model which considers differences between current market interest rates and committed rates. The model also includes assumptions, which estimate fall-out percentages, for commitments to originate loans, and average lives. Fall-out percentages, which range from ten to forty percent, are estimated based upon the difference between current market rates and committed rates. Average lives are based upon estimates for similar types of loans. These measurements use significant unobservable inputs and are classified as Level 3 within the hierarchy.
	The following table presents the fair value measurements of assets recognized in the accompanying balance sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the measurements fall at September 30, 2013 (in thousands):

The following is a summary of valuation techniques utilized by the Company for its significant financial assets and liabilities measured at fair value on a nonrecurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy:
Impaired loans
Loans for which it is probable that the Company will not collect principal and interest due according to contractual terms are measured for impairment. If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and other internal assessments of value. Appraisals are obtained when an impaired loan is deemed to be collateral dependent and at least annually thereafter. Fair value is generally the appraised value less estimated selling costs and may be discounted further if management believes any other factors or events have affected the fair value. Impaired loans are classified within Level 3 of the fair value hierarchy.
The carrying value of impaired loans that were re-measured during the years ended September 30, 2013 and 2012, was $21.2 million and $72.5 million, respectively.
Foreclosed Assets Held For Sale
Foreclosed assets held for sale are initially recorded at fair value as of the date of foreclosure less any estimated selling costs (the “new basis”) and are subsequently carried at the lower of the new basis or fair value less selling costs on the current measurement date. Fair value is estimated through current appraisals, broker price opinions, or listing prices. Appraisals are obtained when the real estate is acquired and at least annually thereafter. Foreclosed assets held for sale are classified within Level 3 of the fair value hierarchy.
The carrying value of foreclosed assets held for sale was $11.3 million and $17.0 million at September 30, 2013 and 2012, respectively. During fiscal 2013, charge-offs and increases in specific reserves related to foreclosed assets held for sale that were re-measured during the period totaled $1.0 million. During fiscal 2012, charge-offs and increases in specific reserves related to foreclosed assets held for sale that were re-measured during the period totaled $3.9 million.
Investment in LLCs
Investments in LLCs are accounted for using the equity method of accounting. On a quarterly basis, these investments are analyzed for impairment in accordance with ASC 323-10-35-32, which states that an other than temporary decline in value of an equity method investment should be recognized. The Company utilizes a multi-faceted approach to measure the potential impairment. The internal model utilizes the following valuation methods: 1) liquidation or appraised values determined by an independent third party appraisal; 2) an on-going business, or discounted cash flows method wherein the cash flows are derived from the sale of fully-developed lots, the development and sale of partially-developed lots, the operation of the homeowner’s association, and the value of raw land obtained from an independent third party appraiser; and 3) an on-going business method, which utilizes the same inputs as method 2, but presumes that cash flows will first be generated from the sale of raw ground and then from the sale of fully-developed and partially-developed lots and the operation of the homeowner’s association. The significant inputs include raw land values, absorption rates of lot sales, and a market discount rate. Management believes this multi-faceted approach is reasonable given the highly subjective nature of the assumptions and the differences in valuation techniques that are utilized within each approach (e.g., order of distribution of assets upon potential liquidation). As a result of this analysis, the Company determined that its investment in Central Platte was materially impaired and recorded an impairment charge of $2.0 million ($1.2 million, net of tax) during the year ended September 30, 2010. During the quarter ended March 31, 2012, list prices of fully-developed lots in Central Platte’s residential development were reduced. The Company incorporated these lower prices into its internal valuation model, which resulted in an additional impairment charge of $200,000 ($123,000, net of tax) during the quarter ended March 31, 2012. No other events have occurred that would indicate any additional impairment of the Company’s investment in Central Platte. Investment in LLCs is classified within Level 3 of the fair value hierarchy.
The carrying value of the Company’s investment in LLCs was $16.5 million and $17.2 million at September 30, 2013 and 2012, respectively
The following methods were used to estimate the fair value of all other financial instruments recognized in the accompanying balance sheets at amounts other than fair value:
Cash and cash equivalents
The carrying amount reported in the consolidated balance sheets is a reasonable estimate of fair value.
Securities and mortgage-backed securities held to maturity
Securities that trade in an active market are valued using market prices, if available. Securities that do not trade in an active market were valued by using industry standard models which utilize various inputs and assumptions such as historical prices of similar securities, estimated delinquencies, defaults, and loss severity.
Stock in Federal Home Loan Bank (“FHLB”)
The carrying value of stock in Federal Home Loan Bank approximates its fair value.
Loans receivable held for investment
Fair values are computed for each loan category using market spreads to treasury securities with similar maturities and management’s estimates of prepayments.
Customer and brokered deposit accounts
The estimated fair values of demand deposits and savings accounts are equal to the amount payable on demand at the reporting date. Fair values of certificates of deposit are computed at fixed spreads to treasury securities with similar maturities.
Advances from FHLB
The estimated fair values of advances from FHLB are determined by discounting the future cash flows of existing advances using rates currently available for new advances with similar terms and remaining maturities.
Subordinated debentures
Fair values are based on quotes from broker-dealers that reflect estimated offer prices.
Commitments to originate, purchase and sell loans
The estimated fair value of commitments to originate, purchase, or sell loans is based on the difference between current levels of interest rates and the committed rates.

	(25) REGULATORY AGREEMENTS
	On April 30, 2010, the Board of Directors of North American Savings Bank, F.S.B. (the “Bank”), a wholly-owned subsidiary of the Company, entered into a Supervisory Agreement with the Office of Thrift Supervision (“OTS”), the Bank’s primary regulator at that time. The agreement required, among other things, that the Bank revise its policies regarding internal asset review, obtain an independent assessment of its allowance for loan and lease losses methodology and conduct an independent third-party review of a portion of its commercial and construction loan portfolios. The agreement also directed the Bank to provide a plan to reduce its classified assets and its reliance on brokered deposits, and restricted the payment of dividends or other capital distributions by the Bank during the period of the agreement. The agreement did not direct the Bank to raise capital, make management or board changes, revise any loan policies or restrict lending growth.
	On April 30, 2010, the Company’s Board of Directors entered into an agreement with the OTS, the Company’s primary regulator at that time. The agreement restricted the payment of dividends or other capital distributions by the Company and restricted the Company’s ability to incur, issue or renew any debt during the period of the agreement.
	The Bank’s Supervisory Agreement and the Company’s agreement with the OTS were assigned to their new primary regulators, the Office of the Comptroller of the Currency (“OCC”) and Board of Governors of the Federal Reserve System (“Federal Reserve Board” or “FRB”), respectively, on July 21, 2011.
	On May 22, 2012, the Board of Directors of the Bank agreed to a Consent Order with the OCC. This Consent Order replaces and terminates the previous Supervisory Agreement. The Consent Order requires that the Bank establish various plans and programs to improve its asset quality and to ensure the adequacy of allowances for loan and lease losses. It requires the Bank to obtain an independent third-party review of its non-homogenous loan portfolios and to enhance its credit administration systems. Among other items, it also requires a written capital maintenance plan to ensure that the Bank’s Tier 1 leverage capital and total risk-based capital ratios remain equal to or greater than 10% and 13%, respectively. As of September 30, 2013, the Bank’s actual Tier 1 leverage capital and total risk-based capital ratios were 17.7% and 25.1%, respectively. The Consent Order does not direct the Bank to raise capital, make management or board changes, or restrict lending.
	On November 29, 2012 the Company’s Board of Directors entered into a formal written agreement with the Federal Reserve Bank of Kansas City, which replaces and terminates the Company’s previous agreement with the OTS. The agreement with FRB restricts the payment of dividends or other capital distributions by the Company, restricts the Company’s ability to incur, increase, or guarantee any debt, and restricts the Company’s ability to purchase or redeem any of its stock. In addition, the agreement restricts the Company and its wholly-owned statutory trust, NASB Preferred Trust I, from making distributions of interest, principal, or other sums on subordinated debentures or trust preferred securities.
	On February 1, 2013, the Board of Directors of the Bank signed an additional Consent Order with the OCC, effective as of that date. This Consent Order requires the Bank to take corrective action to enhance its program for compliance with the Bank Secrecy Act (“BSA”) and other anti-money laundering requirements. The Consent Order requires, among other things, that the Bank improve its processes to better identify and monitor accounts and transactions that pose a greater than normal risk for compliance with the BSA. The Consent Order also requires the Bank to maintain an effective risk assessment process, monitoring mechanisms, training programs and appropriate systems to review the activities of customer accounts.
