Accounting Policies [Abstract]
Basis Of Presentation	BASIS OF PRESENTATION TFS Financial Corporation, a federally chartered stock holding company, conducts its principal activities through its wholly owned subsidiaries. The principal line of business of the Company is retail consumer banking, including mortgage lending, deposit gathering, and, to a much lesser extent, other financial services. As of December 31, 2016 , approximately 80% of the Company’s outstanding shares were owned by a federally chartered mutual holding company, Third Federal Savings and Loan Association of Cleveland, MHC. The thrift subsidiary of TFS Financial Corporation is Third Federal Savings and Loan Association of Cleveland. The accounting and reporting policies followed by the Company conform in all material respects to U.S. GAAP and to general practices in the financial services industry. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for loan losses, the valuation of deferred tax assets, and the determination of pension obligations are particularly subject to change. The unaudited interim consolidated financial statements were prepared without an audit and reflect all adjustments of a normal recurring nature which, in the opinion of management, are necessary to present fairly the consolidated financial condition of the Company at December 31, 2016 , and its results of operations and cash flows for the periods presented. Such adjustments are the only adjustments reflected in the unaudited interim financial statements. In accordance with SEC Regulation S-X for interim financial information, these statements do not include certain information and footnote disclosures required for complete audited financial statements. The Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2016 contains consolidated financial statements and related notes, which should be read in conjunction with the accompanying interim consolidated financial statements. The results of operations for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2017 or for any other period.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share is the amount of earnings attributable to each share of common stock outstanding during the reporting period. Diluted earnings per share is the amount of earnings attributable to each share of common stock outstanding during the reporting period adjusted to include the effect of potentially dilutive common shares. For purposes of computing earnings per share amounts, outstanding shares include shares held by the public, shares held by the ESOP that have been allocated to participants or committed to be released for allocation to participants, the 227,119,132 shares held by Third Federal Savings, MHC, and, for purposes of computing dilutive earnings per share, stock options and restricted stock units with a dilutive impact. Unvested shares awarded pursuant to the Company's restricted stock plans are treated as participating securities in the computation of EPS pursuant to the two-class method as they contain nonforfeitable rights to dividends. The two-class method is an earnings allocation that determines EPS for each class of common stock and participating security. At December 31, 2016 and 2015 , respectively, the ESOP held 5,633,416 and 6,066,756 shares that were neither allocated to participants nor committed to be released to participants. The following is a summary of the Company's earnings per share calculations. For the Three Months Ended December 31, 2016 2015 Income Shares Per share amount Income Shares Per share amount (Dollars in thousands, except per share data) Net income $ 19,610 $ 17,851 Less: income allocated to restricted stock units 204 179 Basic earnings per share: Income available to common shareholders $ 19,406 277,925,724 $ 0.07 $ 17,672 283,834,670 $ 0.06 Diluted earnings per share: Effect of dilutive potential common shares 2,346,731 2,505,383 Income available to common shareholders $ 19,406 280,272,455 $ 0.07 $ 17,672 286,340,053 $ 0.06 The following is a summary of outstanding stock options and restricted stock units that are excluded from the computation of diluted earnings per share because their inclusion would be anti-dilutive.

The contractual terms of U.S. government and agency obligations do not permit the issuer to settle the security at a price less than the par value of the investment. The contractual cash flows of mortgage-backed securities are guaranteed by Fannie Mae, Freddie Mac and Ginnie Mae. REMICs are issued by or backed by securities issued by these governmental agencies. It is expected that the securities would not be settled at a price substantially less than the amortized cost of the investment. The U.S. Treasury Department established financing agreements in 2008 to ensure Fannie Mae and Freddie Mac meet their obligations to holders of mortgage-backed securities that they have issued or guaranteed. Since the decline in value is attributable to changes in interest rates and not credit quality and because the Association has neither the intent to sell the securities nor is it more likely than not the Association will be required to sell the securities for the time periods necessary to recover the amortized cost, these investments are not considered other-than-temporarily impaired.

Receivables [Abstract]
Loans And Allowance For Loan Losses	LOANS AND ALLOWANCE FOR LOAN LOSSES Loans held for investment consist of the following: December 31, September 30, Real estate loans: Residential Core $ 10,257,449 $ 10,069,652 Residential Home Today 118,601 121,938 Home equity loans and lines of credit 1,519,100 1,531,282 Construction 62,788 61,382 Real estate loans 11,957,938 11,784,254 Other consumer loans 3,173 3,116 Add (deduct): Deferred loan expenses, net 22,318 19,384 Loans in process (36,453 ) (36,155 ) Allowance for loan losses (60,447 ) (61,795 ) Loans held for investment, net $ 11,886,529 $ 11,708,804 At December 31, 2016 and September 30, 2016 , respectively, $8,205 and $4,686 of loans were classified as mortgage loans held for sale. A large concentration of the Company’s lending is in Ohio and Florida. As of December 31, 2016 and September 30, 2016 , the percentage of aggregate Residential Core, Home Today and Construction loans held in Ohio were 59% and 60% , respectively, and the percentages held in Florida was 16% as of both dates. As of December 31, 2016 and September 30, 2016 , home equity loans and lines of credit were concentrated in Ohio ( 39% as of both dates), Florida ( 24% as of both dates), and California ( 13% and 14% , respectively). Home Today began as an affordable housing program targeted to benefit low- and moderate-income home buyers. Through this program the Association provided the majority of loans to borrowers who would not otherwise qualify for the Association’s loan products, generally because of low credit scores. Although the credit profiles of borrowers in the Home Today program might be described as sub-prime, Home Today loans generally contain the same features as loans offered to our Residential Core borrowers. Borrowers with a Home Today loan complete financial management education and counseling and were referred to the Association by a sponsoring organization with which the Association partnered as part of the program. Because the Association applied less stringent underwriting and credit standards to the majority of Home Today loans, loans originated under the program have greater credit risk than its traditional residential real estate mortgage loans in the Residential Core portfolio. Effective March 27, 2009, the Home Today underwriting guidelines were changed to be substantially the same as the Association’s traditional first mortgage product and the program focused on financial education and down payment assistance. The majority of loans in this program were originated prior to that date and loans are no longer originated under the Home Today program. As of December 31, 2016 and September 30, 2016 , the principal balance of Home Today loans originated prior to March 27, 2009 was $114,946 and $118,255 , respectively. The Association does not offer, and has not offered, loan products frequently considered to be designed to target sub-prime borrowers containing features such as higher fees or higher rates, negative amortization, a loan-to-value ratio greater than 100%, or pay option adjustable-rate mortgages. An age analysis of the recorded investment in loan receivables that are past due at December 31, 2016 and September 30, 2016 is summarized in the following tables. When a loan is more than one month past due on its scheduled payments, the loan is considered 30 days or more past due. Balances are adjusted for deferred loan fees or expenses and any applicable loans-in-process. 30-59 Days Past Due 60-89 Days Past Due 90 Days or More Past Due Total Past Due Current Total December 31, 2016 Real estate loans: Residential Core $ 7,325 $ 2,803 $ 14,133 $ 24,261 $ 10,244,116 $ 10,268,377 Residential Home Today 5,663 1,762 8,251 15,676 101,502 117,178 Home equity loans and lines of credit 4,123 1,772 5,462 11,357 1,520,441 1,531,798 Construction — — — — 26,450 26,450 Total real estate loans 17,111 6,337 27,846 51,294 11,892,509 11,943,803 Other consumer loans — — — — 3,173 3,173 Total $ 17,111 $ 6,337 $ 27,846 $ 51,294 $ 11,895,682 $ 11,946,976 30-59 Days Past Due 60-89 Days Past Due 90 Days or More Past Due Total Past Due Current Total September 30, 2016 Real estate loans: Residential Core $ 6,653 $ 3,157 $ 15,593 $ 25,403 $ 10,054,211 $ 10,079,614 Residential Home Today 5,271 2,583 7,356 15,210 105,225 120,435 Home equity loans and lines of credit 4,605 1,811 4,932 11,348 1,531,242 1,542,590 Construction — — — — 24,844 24,844 Total real estate loans 16,529 7,551 27,881 51,961 11,715,522 11,767,483 Other consumer loans — — — — 3,116 3,116 Total $ 16,529 $ 7,551 $ 27,881 $ 51,961 $ 11,718,638 $ 11,770,599 At December 31, 2016 and September 30, 2016 , real estate loans include $18,487 and $20,047 , respectively, of loans that were in the process of foreclosure. Loans are placed in non-accrual status when they are contractually 90 days or more past due. Loans restructured in TDRs that were in non-accrual status prior to the restructurings remain in non-accrual status for a minimum of six months after restructuring. Additionally, home equity loans and lines of credit where the customer has a severely delinquent first mortgage loan and loans in Chapter 7 bankruptcy status where all borrowers have filed, and not reaffirmed or been dismissed, are placed in non-accrual status. The recorded investment of loan receivables in non-accrual status is summarized in the following table. Balances are adjusted for deferred loan fees or expenses. December 31, September 30, Real estate loans: Residential Core $ 49,047 $ 51,304 Residential Home Today 20,011 19,451 Home equity loans and lines of credit 18,309 19,206 Total non-accrual loans $ 87,367 $ 89,961 At December 31, 2016 and September 30, 2016 , respectively, the recorded investment in non-accrual loans includes $59,522 and $62,081 , which are performing according to the terms of their agreement, of which $38,899 and $40,546 are loans in Chapter 7 bankruptcy status primarily where all borrowers have filed, and have not reaffirmed or been dismissed. Interest on loans in accrual status, including certain loans individually reviewed for impairment, is recognized in interest income as it accrues, on a daily basis. Accrued interest on loans in non-accrual status is reversed by a charge to interest income and income is subsequently recognized only to the extent cash payments are received. Cash payments on loans in non-accrual status are applied to the oldest scheduled, unpaid payment first. Cash payments on loans with a partial charge-off are applied fully to principal, then to recovery of the charged off amount prior to interest income being recognized. A non-accrual loan is generally returned to accrual status when contractual payments are less than 90 days past due. However, a loan may remain in non-accrual status when collectability is uncertain, such as a TDR that has not met minimum payment requirements, a loan with a partial charge-off, an equity loan or line of credit with a delinquent first mortgage greater than 90 days past due, or a loan in Chapter 7 bankruptcy status where all borrowers have filed, and have not reaffirmed or been dismissed. The number of days past due is determined by the number of scheduled payments that remain unpaid, assuming a period of 30 days between each scheduled payment. The recorded investment in loan receivables at December 31, 2016 and September 30, 2016 is summarized in the following table. The table provides details of the recorded balances according to the method of evaluation used for determining the allowance for loan losses, distinguishing between determinations made by evaluating individual loans and determinations made by evaluating groups of loans not individually evaluated. Balances of recorded investments are adjusted for deferred loan fees or expenses and any applicable loans-in-process.

The analysis provides details of the allowance for loan losses according to the method of evaluation, distinguishing between allowances for loan losses determined by evaluating individual loans and allowances for loan losses determined by evaluating groups of loans collectively. December 31, 2016 September 30, 2016 Individually Collectively Total Individually Collectively Total Real estate loans: Residential Core $ 8,222 $ 6,585 $ 14,807 $ 8,927 $ 6,141 $ 15,068 Residential Home Today 2,732 3,223 5,955 2,979 4,437 7,416 Home equity loans and lines of credit 972 38,708 39,680 722 38,582 39,304 Construction — 5 5 — 7 7 Total $ 11,926 $ 48,521 $ 60,447 $ 12,628 $ 49,167 $ 61,795 At December 31, 2016 and September 30, 2016 , individually evaluated loans that required an allowance were comprised only of loans evaluated for impairment based on the present value of cash flows, such as performing TDRs, and loans with a further deterioration in the fair value of collateral not yet identified as uncollectible. All other individually evaluated loans received a charge-off, if applicable. Because many variables are considered in determining the appropriate level of general valuation allowances, directional changes in individual considerations do not always align with the directional change in the balance of a particular component of the general valuation allowance. At December 31, 2016 and September 30, 2016 , respectively, allowances on individually reviewed loans evaluated for impairment based on the present value of cash flows, such as performing TDRs, were $11,891 and $12,432 . Residential Core mortgage loans represent the largest portion of the residential real estate portfolio. The Company believes overall credit risk is low based on the nature, composition, collateral, products, lien position and performance of the portfolio. The portfolio does not include loan types or structures that have historically experienced severe performance problems at other financial institutions (sub-prime, no documentation or pay option adjustable rate mortgages). As described earlier in this footnote, Home Today loans have greater credit risk than traditional residential real estate mortgage loans. At December 31, 2016 and September 30, 2016 , respectively, approximately 25% and 27% of Home Today loans include private mortgage insurance coverage. The majority of the coverage on these loans was provided by PMI Mortgage Insurance Co., which was seized by the Arizona Department of Insurance and currently pays all claim payments at 71.5% . Appropriate adjustments have been made to the Association’s affected valuation allowances and charge-offs, and estimated loss severity factors were adjusted accordingly for loans evaluated collectively. The amount of loans in the Association's total residential portfolio covered by mortgage insurance provided by PMIC as of December 31, 2016 and September 30, 2016 , respectively, was $81,957 and $91,784 , of which $75,006 and $84,007 was current. The amount of loans in the Association's owned portfolio covered by mortgage insurance provided by Mortgage Guaranty Insurance Corporation as of December 31, 2016 and September 30, 2016 , respectively, was $37,569 and $40,578 of which $37,511 and $40,190 was current. As of December 31, 2016 , MGIC's long-term debt rating, as published by the major credit rating agencies, did not meet the requirements to qualify as "high credit quality"; however, MGIC continues to make claims payments in accordance with its contractual obligations and the Association has not increased its estimated loss severity factors related to MGIC's claim paying ability. No other loans were covered by mortgage insurers that were deferring claim payments or which were assessed as being non-investment grade. Home equity loans and lines of credit represent a significant portion of the residential real estate portfolio, primarily comprised of home equity lines of credit. Post-origination deterioration in economic and housing market conditions may impact a borrower's ability to afford the higher payments required during the end of draw repayment period that follows the period of interest only payments on home equity lines of credit originated prior to 2012 or the ability to secure alternative financing. Beginning in February 2013, the terms on new home equity lines of credit included monthly principal and interest payments throughout the entire term to minimize the potential payment differential between the during draw and after draw periods. The Association originates construction loans to individuals for the construction of their personal single-family residence by a qualified builder (construction/permanent loans). The Association’s construction/permanent loans generally provide for disbursements to the builder or sub-contractors during the construction phase as work progresses. During the construction phase, the borrower only pays interest on the drawn balance. Upon completion of construction, the loan converts to a permanent amortizing loan without the expense of a second closing. The Association offers construction/permanent loans with fixed or adjustable rates, and a current maximum loan-to-completed-appraised value ratio of 85%. Other consumer loans are comprised of loans secured by certificate of deposit accounts, which are fully recoverable in the event of non-payment. For all classes of loans, a loan is considered impaired when, based on current information and events, it is probable that the Association will be unable to collect the scheduled payments of principal and interest according to the contractual terms of the loan agreement. Factors considered in determining that a loan is impaired may include the deteriorating financial condition of the borrower indicated by missed or delinquent payments, a pending legal action, such as bankruptcy or foreclosure, or the absence of adequate security for the loan. The recorded investment and the unpaid principal balance of impaired loans, including those reported as TDRs, as of December 31, 2016 and September 30, 2016 are summarized as follows. Balances of recorded investments are adjusted for deferred loan fees or expenses.

The average recorded investment in impaired loans and the amount of interest income recognized during the period that the loans were impaired are summarized below. For the Three Months Ended December 31, 2016 2015 Average Recorded Investment Interest Income Recognized Average Recorded Investment Interest Income Recognized With no related IVA recorded: Residential Core $ 52,600 $ 311 $ 60,931 $ 369 Residential Home Today 19,927 107 22,523 150 Home equity loans and lines of credit 20,214 67 21,940 64 Construction — — — — Total $ 92,741 $ 485 $ 105,394 $ 583 With an IVA recorded: Residential Core $ 53,145 $ 510 $ 56,696 $ 590 Residential Home Today 30,810 377 34,452 432 Home equity loans and lines of credit 16,087 478 11,353 77 Construction — — 213 — Total $ 100,042 $ 1,365 $ 102,714 $ 1,099 Total impaired loans: Residential Core $ 105,745 $ 821 $ 117,627 $ 959 Residential Home Today 50,737 484 56,975 582 Home equity loans and lines of credit 36,301 545 33,293 141 Construction — — 213 — Total $ 192,783 $ 1,850 $ 208,108 $ 1,682 Interest on loans in non-accrual status is recognized on a cash basis. The amount of interest income on impaired loans recognized using a cash basis method was $356 for the three months ended December 31, 2016 and $449 for the three months ended December 31, 2015 . Cash payments on loans with a partial charge-off are applied fully to principal, then to recovery of the charged off amount prior to interest income being recognized. Interest income on the remaining impaired loans is recognized on an accrual basis. Charge-offs on residential mortgage loans, home equity loans and lines of credit, and construction loans are recognized when triggering events, such as foreclosure actions, short sales, or deeds accepted in lieu of repayment, result in less than full repayment of the recorded investment in the loans. Partial or full charge-offs are also recognized for the amount of impairment on loans considered collateral dependent that meet the conditions described below. • For residential mortgage loans, payments are 180 days delinquent; • For home equity lines of credit, equity loans, and residential loans restructured in a TDR, payments are greater than 90 days delinquent; • For all classes of loans, a sheriff sale is scheduled within 60 days to sell the collateral securing the loan; • For all classes of loans, all borrowers have been discharged of their obligation through a Chapter 7 bankruptcy; • For all classes of loans, within 60 days of notification, all borrowers obligated on the loan have filed Chapter 7 bankruptcy and have not reaffirmed or been dismissed; • For all classes of loans, a borrower obligated on a loan has filed bankruptcy and the loan is greater than 30 days delinquent; and • For all classes of loans, it becomes evident that a loss is probable. Collateral dependent residential mortgage loans and construction loans are charged off to the extent the recorded investment in a loan, net of anticipated mortgage insurance claims, exceeds the fair value less costs to dispose of the underlying property. Management can determine the loan is uncollectible for reasons such as foreclosures exceeding a reasonable time frame and recommend a full charge-off. Home equity loans or lines of credit are charged off to the extent the recorded investment in the loan plus the balance of any senior liens exceeds the fair value less costs to dispose of the underlying property or management determines the collateral is not sufficient to satisfy the loan. A loan in any portfolio that is identified as collateral dependent will continue to be reported as impaired until it is no longer considered collateral dependent, is less than 30 days past due and does not have a prior charge-off. A loan in any portfolio that has a partial charge-off consequent to impairment evaluation will continue to be individually evaluated for impairment until, at a minimum, the impairment has been recovered. The following summarizes the effective dates of charge-off policies that changed or were first implemented during the current and previous four fiscal years and the portfolios to which those policies apply. Effective Date Policy Portfolio(s) Affected 6/30/2014 A loan is considered collateral dependent and any collateral shortfall is charged off when, within 60 days of notification, all borrowers obligated on a loan filed Chapter 7 bankruptcy and have not reaffirmed or been dismissed (1) All ____________________________ (1) Prior to 6/30/2014, collateral shortfalls on loans in Chapter 7 bankruptcy were charged off when all borrowers were discharged of the obligation or when the loan was 30 days or more past due. Loans restructured in TDRs that are not evaluated based on collateral are separately evaluated for impairment on a loan by loan basis at the time of restructuring and at each subsequent reporting date for as long as they are reported as TDRs. The impairment evaluation is based on the present value of expected future cash flows discounted at the effective interest rate of the original loan. Expected future cash flows include a discount factor representing a potential for default. Valuation allowances are recorded for the excess of the recorded investments over the result of the cash flow analysis. Loans discharged in Chapter 7 bankruptcy are reported as TDRs and also evaluated based on the present value of expected future cash flows unless evaluated based on collateral. We evaluate these loans using the expected future cash flows because we expect the borrower, not liquidation of the collateral, to be the source of repayment for the loan. Other consumer loans are not considered for restructuring. A loan restructured in a TDR is classified as an impaired loan for a minimum of one year. After one year, that loan may be reclassified out of the balance of impaired loans if the loan was restructured to yield a market rate for loans of similar credit risk at the time of restructuring and the loan is not impaired based on the terms of the restructuring agreement. No loans whose terms were restructured in TDRs were reclassified from impaired loans during the three months ended December 31, 2016 and December 31, 2015. The recorded investment in TDRs by type of concession as of December 31, 2016 and September 30, 2016 is shown in the tables below.

Among other requirements, a subsequent restructuring may be available for a borrower upon the expiration of temporary restructuring terms if the borrower cannot return to regular loan payments. If the borrower is experiencing an income curtailment that temporarily has reduced his/her capacity to repay, such as loss of employment, reduction of hours, non-paid leave or short term disability, a temporary restructuring is considered. If the borrower lacks the capacity to repay the loan at the current terms due to a permanent condition, a permanent restructuring is considered. In evaluating the need for a subsequent restructuring, the borrower’s ability to repay is generally assessed utilizing a debt to income and cash flow analysis. As the economy slowly improves, the need for multiple restructurings has begun to abate. Loans discharged in Chapter 7 bankruptcy are classified as multiple restructurings if the loan's original terms had also been restructured by the Association. For all loans restructured during the three months ended December 31, 2016 and December 31, 2015 (set forth in the tables below), the pre-restructured outstanding recorded investment was not materially different from the post-restructured outstanding recorded investment. The following tables set forth the recorded investment in TDRs restructured during the periods presented, according to the types of concessions granted.

Pass loans are assets well protected by the current paying capacity of the borrower. Special Mention loans have a potential weakness, as evaluated based on delinquency status, that the Association feels deserve management’s attention and may result in further deterioration in their repayment prospects and/or the Association’s credit position. Substandard loans are inadequately protected by the current payment capacity of the borrower or the collateral pledged with a defined weakness that jeopardizes the liquidation of the debt. Also included in Substandard are performing home equity loans and lines of credit where the customer has a severely delinquent first mortgage to which the performing home equity loan or line of credit is subordinate and loans in Chapter 7 bankruptcy status where all borrowers have filed, and have not reaffirmed or been dismissed. Loss loans are considered uncollectible and are charged off when identified. The following tables provide information about the credit quality of residential loan receivables by an internally assigned grade. Balances are adjusted for deferred loan fees or expenses and any applicable LIP.

At December 31, 2016 and September 30, 2016 , respectively, there were $5,941 and $6,346 of loans classified substandard and $3,896 and $4,122 of loans designated special mention that are not included in the recorded investment of impaired loans; rather, they are included in loans collectively evaluated for impairment. Other consumer loans are internally assigned a grade of nonperforming when they become 90 days or more past due. At December 31, 2016 and September 30, 2016 , no consumer loans were graded as nonperforming.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and in various state and city jurisdictions. With a few exceptions, the Company is no longer subject to income tax examinations in its major jurisdictions for tax years prior to 2013. The Company recognizes interest and penalties on income tax assessments or income tax refunds, where applicable, in the financial statements as a component of its provision for income taxes. The Company’s effective income tax rate was 30.8% and 34.2% for the three months ended December 31, 2016 and 2015, respectively. The decrease in the effective rate for the three months ended December 31, 2016 compared to the same period 2015 was primarily due to the adoption of ASU 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting on October 1, 2016. Additional information regarding this adoption is provided in Note 13. Recent Accounting Pronouncements . The Company makes certain investments in limited partnerships which invest in affordable housing projects that qualify for the Low Income Housing Tax Credit. The Company acts as a limited partner in these investments and does not exert control over the operating or financial policies of the partnership. The Company accounts for its interests in LIHTCs using the proportional amortization method. The impact of the Company's investments in tax credit entities on the provision for income taxes was not material during the three months ended December 31, 2016 and December 31, 2015 .

Defined Benefit Plan	DEFINED BENEFIT PLAN The Third Federal Savings Retirement Plan (the “Plan”) is a defined benefit pension plan. Effective December 31, 2002, the Plan was amended to limit participation to employees who met the Plan’s eligibility requirements on that date. Effective December 31, 2011, the Plan was amended to freeze future benefit accruals for participants in the Plan. After December 31, 2002, employees not participating in the Plan, upon meeting the applicable eligibility requirements, and those eligible participants who no longer receive service credits under the Plan, participate in a separate tier of the Company’s defined contribution 401(k) Savings Plan. Benefits under the Plan are based on years of service and the employee’s average annual compensation (as defined in the Plan) through December 31, 2011. The funding policy of the Plan is consistent with the funding requirements of U.S. federal and other governmental laws and regulations. The components of net periodic cost recognized in the statements of income are as follows: Three Months Ended December 31, 2016 2015 Interest cost $ 767 $ 822 Expected return on plan assets (1,033 ) (1,028 ) Amortization of net loss 531 386 Net periodic cost $ 265 $ 180 There were no required minimum employer contributions during the three months ended December 31, 2016 .

Equity Incentive Plan	EQUITY INCENTIVE PLAN In December 2016 , 293,200 options to purchase our common stock and 69,300 restricted stock units were granted to certain directors, officers and employees of the Company. The awards were made pursuant to the shareholder-approved 2008 Equity Incentive Plan. During the three months ended December 31, 2016 and 2015 , the Company recorded $1,060 and $1,708 , respectively, of stock-based compensation expense, comprised of stock option expense of $457 and $666 , respectively, and restricted stock units expense of $603 and $1,042 , respectively. At December 31, 2016 , 4,579,427 shares were subject to options, with a weighted average exercise price of $13.20 per share and a weighted average grant date fair value of $2.97 per share. Expected future expense related to the 1,494,161 non-vested options outstanding as of December 31, 2016 is $2,635 over a weighted average period of 2.5 years. At December 31, 2016 , 678,231 restricted stock units, with a weighted average grant date fair value of $14.17 per unit, are unvested. Expected future compensation expense relating to the 1,190,624 restricted stock units outstanding as of December 31, 2016 is $3,184 over a weighted average period of 1.8 years.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingent Liabilities	COMMITMENTS AND CONTINGENT LIABILITIES In the normal course of business, the Company enters into commitments with off-balance sheet risk to meet the financing needs of its customers. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments to originate loans generally have fixed expiration dates of 60 to 360 days or other termination clauses and may require payment of a fee. Unfunded commitments related to home equity lines of credit generally expire from five to 10 years following the date that the line of credit was established, subject to various conditions, including compliance with payment obligations, adequacy of collateral securing the line and maintenance of a satisfactory credit profile by the borrower. Since some of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Off-balance sheet commitments to extend credit involve elements of credit risk and interest rate risk in excess of the amount recognized in the consolidated statements of condition. The Company’s exposure to credit loss in the event of nonperformance by the other party to the commitment is represented by the contractual amount of the commitment. The Company generally uses the same credit policies in making commitments as it does for on-balance-sheet instruments. Interest rate risk on commitments to extend credit results from the possibility that interest rates may have moved unfavorably from the position of the Company since the time the commitment was made. At December 31, 2016 , the Company had commitments to originate loans as follows: Fixed-rate mortgage loans $ 321,244 Adjustable-rate mortgage loans 442,713 Equity loans and lines of credit 52,305 Total $ 816,262 At December 31, 2016 , the Company had unfunded commitments outstanding as follows: Equity lines of credit $ 1,292,576 Construction loans 36,453 Private equity investments 11,541 Total $ 1,340,570 At December 31, 2016 , the unfunded commitment on home equity lines of credit, including commitments for accounts suspended as a result of material default or a decline in equity, is $1,405,547 . In management's opinion, the above commitments will be funded through normal operations. The Company and its subsidiaries are subject to various legal actions arising in the normal course of business. In the opinion of management, the resolution of these legal actions is not expected to have a material adverse effect on the Company’s financial condition, results of operation, or statements of cash flows.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	FAIR VALUE Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date under current market conditions and a fair value framework is established whereby assets and liabilities measured at fair value are grouped into three levels of a fair value hierarchy, based on the transparency of inputs and the reliability of assumptions used to estimate fair value. The Company’s policy is to recognize transfers between levels of the hierarchy as of the end of the reporting period in which the transfer occurs. The three levels of inputs are defined as follows: Level 1 – quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 – quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets with few transactions, or model-based valuation techniques using assumptions that are observable in the market. Level 3 – a company’s own assumptions about how market participants would price an asset or liability. As permitted under the fair value guidance in U.S. GAAP, the Company elects to measure at fair value mortgage loans classified as held for sale that are subject to pending agency contracts to securitize and sell loans. This election is expected to reduce volatility in earnings related to market fluctuations between the contract trade and settlement dates. At December 31, 2016 and September 30, 2016 there were no loans held for sale subject to pending agency contracts for which the fair value option was elected. Presented below is a discussion of the methods and significant assumptions used by the Company to estimate fair value. Investment Securities Available for Sale— Investment securities available for sale are recorded at fair value on a recurring basis. At December 31, 2016 and September 30, 2016 , respectively, this includes $524,175 and $517,866 of investments in highly liquid collateralized mortgage obligations issued by Fannie Mae, Freddie Mac and Ginnie Mae. Both are measured using the market approach. The fair values of collateralized mortgage obligations represent unadjusted price estimates obtained from third party independent nationally recognized pricing services using pricing models or quoted prices of securities with similar characteristics and are included in Level 2 of the hierarchy. Third party pricing is reviewed on a monthly basis for reasonableness based on the market knowledge and experience of company personnel that interact daily with the markets for these types of securities. Mortgage Loans Held for Sale— The fair value of mortgage loans held for sale is estimated on an aggregate basis using a market approach based on quoted secondary market pricing for loan portfolios with similar characteristics. Loans held for sale are carried at the lower of cost or fair value except, as described above, the Company elects the fair value measurement option for mortgage loans held for sale subject to pending agency contracts to securitize and sell loans. Loans held for sale are included in Level 2 of the hierarchy. At December 31, 2016 and September 30, 2016 there were $8,205 and $4,686 , respectively, of loans held for sale carried at fair value and at cost, respectively. Impaired Loans — Impaired loans represent certain loans held for investment that are subject to a fair value measurement under U.S. GAAP because they are individually evaluated for impairment and that impairment is measured using a fair value measurement, such as the fair value of the underlying collateral. Impairment is measured using a market approach based on the fair value of the collateral less estimated costs to dispose for loans the Company considers to be collateral-dependent due to a delinquency status or other adverse condition severe enough to indicate that the borrower can no longer be relied upon as the continued source of repayment. These conditions are described more fully in Note 4. Loans and Allowance for Loan Losses . Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date under current market conditions and a fair value framework is established whereby assets and liabilities measured at fair value are grouped into three levels of a fair value hierarchy, based on the transparency of inputs and the reliability of assumptions used to estimate fair value. The Company’s policy is to recognize transfers between levels of the hierarchy as of the end of the reporting period in which the transfer occurs. The three levels of inputs are defined as follows: Loans held for investment that have been restructured in TDRs and are performing according to the restructured terms of the loan agreement are individually evaluated for impairment using the present value of future cash flows based on the loan’s effective interest rate, which is not a fair value measurement. At December 31, 2016 and September 30, 2016 , respectively, this included $101,190 and $102,079 in recorded investment of TDRs with related allowances for loss of $11,891 and $12,432 . Real Estate Owned— Real estate owned includes real estate acquired as a result of foreclosure or by deed in lieu of foreclosure and is carried at the lower of the cost basis or fair value less estimated costs to dispose. Fair value is estimated under the market approach using independent third party appraisals. As these properties are actively marketed, estimated fair values may be adjusted by management to reflect current economic and market conditions. At December 31, 2016 and September 30, 2016 , these adjustments were not significant to reported fair values. At December 31, 2016 and September 30, 2016 , respectively, $3,137 and $4,192 of real estate owned is included in Level 3 of the hierarchy with assets measured at fair value on a non-recurring basis where the cost basis equals or exceeds the estimate of fair values less costs to dispose of these properties. Real estate owned, as reported in the Consolidated Statements of Condition, includes estimated costs to dispose of $416 and $521 related to properties measured at fair value and $2,940 and $3,132 of properties carried at their original or adjusted cost basis at December 31, 2016 and September 30, 2016 , respectively. Derivatives— Derivative instruments include interest rate locks on commitments to originate loans for the held for sale portfolio, forward commitments on contracts to deliver mortgage loans, and interest rate swaps designated as cash flow hedges. Derivatives not designated as cash flow hedges are reported at fair value in other assets or other liabilities on the Consolidated Statement of Condition with changes in value recorded in current earnings. Derivatives qualifying as cash flow hedges, when highly effective, are reported at fair value in other assets or other liabilities on the Consolidated Statement of Condition with changes in value recorded in OCI. Should the hedge no longer be considered effective, the ineffective portion of the change in fair value is recorded directly in earnings in the period in which the change occurs. See Note 12. Derivative Instruments for additional details. Fair value of forward commitments is estimated using a market approach based on quoted secondary market pricing for loan portfolios with characteristics similar to loans underlying the derivative contracts. The fair value of interest rate swaps is estimated using a discounted cash flow method that incorporates current market interest rates and other market parameters. The fair value of interest rate lock commitments is adjusted by a closure rate based on the estimated percentage of commitments that will result in closed loans. The range and weighted average impact of the closure rate is included in quantitative information about significant unobservable inputs later in this note. A significant change in the closure rate may result in a significant change in the ending fair value measurement of these derivatives relative to their total fair value. Because the closure rate is a significantly unobservable assumption, interest rate lock commitments are included in Level 3 of the hierarchy. Forward commitments on contracts to deliver mortgage loans and interest rate swaps are included in Level 2 of the hierarchy. Assets and liabilities carried at fair value on a recurring basis in the Consolidated Statements of Condition at December 31, 2016 and September 30, 2016 are summarized below. There were no liabilities carried at fair value on a recurring basis at December 31, 2016.

Cash and Due from Banks, Interest Earning Cash Equivalents, Cash Collateral Received from or Held by Counterparty— The carrying amount is a reasonable estimate of fair value. Investment and Mortgage-Backed Securities — Estimated fair value for investment and mortgage-backed securities is based on quoted market prices, when available. If quoted prices are not available, management will use as part of their estimation process fair values which are obtained from third party independent nationally recognized pricing services using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Mortgage Loans Held for Sale— Fair value of mortgage loans held for sale is based on quoted secondary market pricing for loan portfolios with similar characteristics. Loans— For mortgage loans held for investment and other loans, fair value is estimated by discounting contractual cash flows adjusted for prepayment estimates using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining term. The use of current rates to discount cash flows reflects current market expectations with respect to credit exposure. Impaired loans are measured at the lower of cost or fair value as described earlier in this footnote. Federal Home Loan Bank Stock— It is not practical to estimate the fair value of FHLB stock due to restrictions on its transferability. The fair value is estimated to be the carrying value, which is par. All transactions in capital stock of the FHLB Cincinnati are executed at par. Deposits— The fair value of demand deposit accounts is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using discounted cash flows and rates currently offered for deposits of similar remaining maturities. Borrowed Funds— Estimated fair value for borrowed funds is estimated using discounted cash flows and rates currently charged for borrowings of similar remaining maturities. Accrued Interest Receivable, Borrowers’ Advances for Insurance and Taxes, and Principal, Interest and Related Escrow Owed on Loans Serviced— The carrying amount is a reasonable estimate of fair value. Derivatives— Fair value is estimated based on the valuation techniques and inputs described earlier in this footnote.

Summary of Derivative Instruments [Abstract]
Derivative Instruments	DERIVATIVE INSTRUMENTS The Company enters into interest rate swaps to add stability to interest expense and manage exposure to interest rate movements as part of an overall risk management strategy. For hedges of the Company's borrowing program, interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed payments. These derivatives are used to hedge the forecasted cash outflows associated with the Company's FHLB borrowings. Cash flow hedges are assessed for effectiveness using regression analysis. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in OCI and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Ineffectiveness is generally measured as the amount by which the cumulative change in the fair value of the hedging instrument exceeds or is substantially less than the present value of the cumulative change in the hedged item's expected cash flows attributable to the risk being hedged. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings for the period in which it occurs. The following table presents additional information about the interest rate swaps used in the Company's asset liability management strategy. Cash Flow Hedges December 31, 2016 September 30, 2016 Notional value $ 700,000 $ 600,000 Fair value 17,307 (2,108 ) Weighted-average rate receive 0.94 % 0.79 % Weighted-average rate pay 1.28 % 1.21 % Average maturity (in years) 4.4 4.5 Amounts reported in AOCI related to derivatives are reclassified to interest expense during the same period in which the hedged transaction affects earnings. During the next twelve months, the Company estimates that $923 of the amounts reported in AOCI will be reclassified to interest expense. The Company enters into forward commitments for the sale of mortgage loans principally to protect against the risk of adverse interest rate movements on net income. The Company recognizes the fair value of such contracts when the characteristics of those contracts meet the definition of a derivative. These derivatives are not designated in a hedging relationship; therefore, gains and losses are recognized immediately in the statement of income. There were no forward commitments for the sale of mortgage loans at December 31, 2016 or September 30, 2016 . In addition, the Company is party to derivative instruments when it enters into commitments to originate a portion of its loans, which when funded, are classified as held for sale. Such commitments are not designated in a hedging relationship; therefore, gains and losses are recognized immediately in the statement of income.

The Company's exposure is limited to the replacement value of the contracts rather than the notional or principal amounts. Credit risk is minimized through counterparty collateral, transaction limits and monitoring procedures. Swap transactions that are handled by a registered clearing broker are cleared though the broker to a registered clearing organization. The clearing organization establishes daily cash and upfront cash or securities margin requirements to cover potential exposure in the event of default. This process shifts the risk away from the counterparty, since the clearing organization acts as the middleman on each cleared transaction. The fair values of derivative instruments are presented on a gross basis, even when the derivative instruments are subject to master netting arrangements. Cash collateral payables or receivables associated with the derivative instruments are not added to or netted against the fair value amounts. The Company’s interest rate swaps are cleared through a registered clearing broker. At December 31, 2016 , the Company had no interest rate swaps in liability positions. At September 30, 2016 , the balance of collateral posted by the Company for derivative liabilities was $10,480 .

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS A dopted during the quarter ended December 31, 2016 In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for share-based payment transactions, including accounting for income taxes, forfeitures, and classification in the statement of cash flows. Additionally, the ASU expanded the threshold on statutory tax withholding requirements used to qualify for equity classification. This accounting guidance is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is permitted. The Company early adopted the revised guidance on October 1, 2016. The impacts of this adoption on the Company's consolidated financial statements are described below. • On a prospective basis, all excess tax benefits and deficiencies related to share-based payments are recognized as income tax expense or benefit. For the three months ended December 31, 2016, $919 was recognized as income tax benefit rather than additional paid-in capital as a result of this adoption. Excess tax benefits and tax deficiencies are considered discrete items in the reporting period they occur and are not included in the estimate of the Company's annual effective tax rate. • On a prospective basis, excess tax benefits and deficiencies related to share-based payments are classified as operating activities on the Statements of Cash Flows. No change was applied to prior periods. • The Company elects to account for forfeitures as they occur, rather than estimate expected forfeitures. This election was applied using a modified retrospective transition method. The cumulative-effect adjustment to equity recognized as of October 1, 2016 was not material. In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810), Amendments to the Consolidation Analysis. This accounting guidance changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The new guidance amends the current accounting guidance to address limited partnerships and similar legal entities, certain investment funds, fees paid to a decision maker or service provider, and the impact of fee arrangements and related parties on the primary beneficiary determination. In addition, the FASB issued ASU 2016-17, Consolidation (Topic 810), Interests Held through Related Parties that are under Common Control in October 2016, amending the consolidation guidance on how a reporting entity that is the single decision maker of a Variable Interest Entity (VIE) should treat indirect interests in the entity held through related parties that are under common control. Both accounting guidances are effective for annual periods beginning after December 15, 2015. A reporting entity may apply the ASU by using a modified retrospective approach (by recording a cumulative-effect adjustment to equity as of the beginning of the year of adoption) or a full retrospective approach (by restating all periods presented). The adoption of this accounting guidance did not have a material effect on the Company's financial condition or results and operations. Pending as of December 31, 2016 In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments in this Update address eight specific cash flow issues with the objective of reducing the existing diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and Other Topics. Current GAAP either is unclear or does not include specific guidance on these eight issues. Additionally, in November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) Restricted Cash, which requires restricted cash or restricted cash equivalents be included in beginning-of-period and end-of-period cash totals and changes in this classification be explained separately. The amendments in both these Updates are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact this new standard will have on its financial condition and results of operations. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The amendments in this Update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and require consideration of a broader range of information, including reasonably supportable forecasts, in the measurement of expected credit losses. The amendments expand disclosures of credit quality indicators, requiring disaggregation by year of origination (vintage). Additionally, credit losses on available for sale debt securities will be recognized as an allowance rather than a write-down, with reversals permitted as credit loss estimates decline. An entity will apply the amendments in this Update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). For public business entities that are SEC filers, the amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact that this accounting guidance may have on its financial condition and results of operations. In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815), Effects of Derivative Contract Novations on Existing Hedge Accounting Relationships. This amendment clarifies that a change in counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedging accounting criteria continue to be met. This accounting guidance will be effective for financial statements issued for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years. The adoption of this accounting guidance is not expected to materially affect the Company's financial condition and results of operations. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This guidance changes the accounting treatment of leases by requiring lessees to recognize operating leases on the balance sheet as lease assets (a right-to-use asset) and lease liabilities (a liability to make lease payments), measured on a discounted basis. An accounting policy election to not recognize operating leases with terms of 12 months or less as assets and liabilities is permitted. This guidance will be effective for the fiscal year beginning after December 15, 2018. A modified retrospective approach is required that includes a number of optional practical expedients to address leases that commenced before the effective date. The Company is currently evaluating the impact this new standard will have on its financial condition and results of operations. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. This accounting guidance requires equity investments not accounted for under the equity method of accounting or consolidated to be measured at fair value with changes recognized in net income. If there are no readily determinable fair values, the guidance allows entities to measure investments at cost less impairment, whereby impairment is based on a qualitative assessment. The guidance eliminates the requirement to disclose the methods and significant assumptions used to estimate fair value of financial instruments measured at amortized cost. If an entity has elected the fair value option to measure liabilities, the new accounting guidance requires the portion of the change in fair value of a liability resulting from credit risk to be presented in OCI. This accounting and disclosure guidance will be effective for the fiscal year beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact that this accounting guidance may have on its financial condition and results of operations. In May 2015, the FASB issued ASU 2015-07, Fair Value Measurement (Topic 820), Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share. This guidance eliminates the requirement to categorize investments measured at net value per share (or its equivalent) using the practical expedient in the fair value hierarchy table and eliminates certain disclosures required for these investments. Entities will continue to provide information helpful to understanding the nature and risks of these investments and whether the investments, if sold, are probable of being sold at amounts different from net asset value. The amendments in this Update are effective for public companies for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. This guidance will only affect the Company's year-end disclosures related to pension fair value. Early adoption is permitted. The adoption of this disclosure guidance is not expected to materially affect the Company's financial condition and results of operations. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), that revises the criteria for determining when to recognize revenue from contracts with customers and expands disclosure requirements. This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. In August 2015, the FASB issued ASU 2015-14 which defers the effective date of ASU 2014-09 by one year, annual reporting periods and interim period within those annual periods beginning after December 15, 2017. Additionally, the FASB has recently issued and proposed updates to certain aspects of the guidance. The Company's preliminary analysis suggests that the adoption of this accounting guidance is not expected to have a material effect on its financial condition and results of operations. The Company has determined that all other recently issued accounting pronouncements will not have a material impact on the Company's consolidated financial statements or do not apply to its operations.

Accounting Policies [Abstract]
Business, Policy	TFS Financial Corporation, a federally chartered stock holding company, conducts its principal activities through its wholly owned subsidiaries. The principal line of business of the Company is retail consumer banking, including mortgage lending, deposit gathering, and, to a much lesser extent, other financial services. As of December 31, 2016 , approximately 80% of the Company’s outstanding shares were owned by a federally chartered mutual holding company, Third Federal Savings and Loan Association of Cleveland, MHC. The thrift subsidiary of TFS Financial Corporation is Third Federal Savings and Loan Association of Cleveland.
Basis of Accounting, Policy	The accounting and reporting policies followed by the Company conform in all material respects to U.S. GAAP and to general practices in the financial services industry. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for loan losses, the valuation of deferred tax assets, and the determination of pension obligations are particularly subject to change. The unaudited interim consolidated financial statements were prepared without an audit and reflect all adjustments of a normal recurring nature which, in the opinion of management, are necessary to present fairly the consolidated financial condition of the Company at December 31, 2016 , and its results of operations and cash flows for the periods presented. Such adjustments are the only adjustments reflected in the unaudited interim financial statements. In accordance with SEC Regulation S-X for interim financial information, these statements do not include certain information and footnote disclosures required for complete audited financial statements. The Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2016 contains consolidated financial statements and related notes, which should be read in conjunction with the accompanying interim consolidated financial statements. The results of operations for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2017 or for any other period.
Loans and Leases Receivable, Nonaccrual Loan and Lease Status, Policy	Interest on loans in accrual status, including certain loans individually reviewed for impairment, is recognized in interest income as it accrues, on a daily basis. Accrued interest on loans in non-accrual status is reversed by a charge to interest income and income is subsequently recognized only to the extent cash payments are received. Cash payments on loans in non-accrual status are applied to the oldest scheduled, unpaid payment first. Cash payments on loans with a partial charge-off are applied fully to principal, then to recovery of the charged off amount prior to interest income being recognized. A non-accrual loan is generally returned to accrual status when contractual payments are less than 90 days past due. However, a loan may remain in non-accrual status when collectability is uncertain, such as a TDR that has not met minimum payment requirements, a loan with a partial charge-off, an equity loan or line of credit with a delinquent first mortgage greater than 90 days past due, or a loan in Chapter 7 bankruptcy status where all borrowers have filed, and have not reaffirmed or been dismissed. The number of days past due is determined by the number of scheduled payments that remain unpaid, assuming a period of 30 days between each scheduled payment. When a loan is more than one month past due on its scheduled payments, the loan is considered 30 days or more past due. Loans are placed in non-accrual status when they are contractually 90 days or more past due. Loans restructured in TDRs that were in non-accrual status prior to the restructurings remain in non-accrual status for a minimum of six months after restructuring. Additionally, home equity loans and lines of credit where the customer has a severely delinquent first mortgage loan and loans in Chapter 7 bankruptcy status where all borrowers have filed, and not reaffirmed or been dismissed, are placed in non-accrual status. Charge-offs on residential mortgage loans, home equity loans and lines of credit, and construction loans are recognized when triggering events, such as foreclosure actions, short sales, or deeds accepted in lieu of repayment, result in less than full repayment of the recorded investment in the loans. Partial or full charge-offs are also recognized for the amount of impairment on loans considered collateral dependent that meet the conditions described below. • For residential mortgage loans, payments are 180 days delinquent; • For home equity lines of credit, equity loans, and residential loans restructured in a TDR, payments are greater than 90 days delinquent; • For all classes of loans, a sheriff sale is scheduled within 60 days to sell the collateral securing the loan; • For all classes of loans, all borrowers have been discharged of their obligation through a Chapter 7 bankruptcy; • For all classes of loans, within 60 days of notification, all borrowers obligated on the loan have filed Chapter 7 bankruptcy and have not reaffirmed or been dismissed; • For all classes of loans, a borrower obligated on a loan has filed bankruptcy and the loan is greater than 30 days delinquent; and • For all classes of loans, it becomes evident that a loss is probable. Collateral dependent residential mortgage loans and construction loans are charged off to the extent the recorded investment in a loan, net of anticipated mortgage insurance claims, exceeds the fair value less costs to dispose of the underlying property. Management can determine the loan is uncollectible for reasons such as foreclosures exceeding a reasonable time frame and recommend a full charge-off. Home equity loans or lines of credit are charged off to the extent the recorded investment in the loan plus the balance of any senior liens exceeds the fair value less costs to dispose of the underlying property or management determines the collateral is not sufficient to satisfy the loan. A loan in any portfolio that is identified as collateral dependent will continue to be reported as impaired until it is no longer considered collateral dependent, is less than 30 days past due and does not have a prior charge-off. A loan in any portfolio that has a partial charge-off consequent to impairment evaluation will continue to be individually evaluated for impairment until, at a minimum, the impairment has been recovered. The following summarizes the effective dates of charge-off policies that changed or were first implemented during the current and previous four fiscal years and the portfolios to which those policies apply. Effective Date Policy Portfolio(s) Affected 6/30/2014 A loan is considered collateral dependent and any collateral shortfall is charged off when, within 60 days of notification, all borrowers obligated on a loan filed Chapter 7 bankruptcy and have not reaffirmed or been dismissed (1) All ____________________________ (1) Prior to 6/30/2014, collateral shortfalls on loans in Chapter 7 bankruptcy were charged off when all borrowers were discharged of the obligation or when the loan was 30 days or more past due.
Loans and Allowance for Loan Losses, Impaired Loan, Policy	For all classes of loans, a loan is considered impaired when, based on current information and events, it is probable that the Association will be unable to collect the scheduled payments of principal and interest according to the contractual terms of the loan agreement. Factors considered in determining that a loan is impaired may include the deteriorating financial condition of the borrower indicated by missed or delinquent payments, a pending legal action, such as bankruptcy or foreclosure, or the absence of adequate security for the loan.
Loans and Allowance for Loan Losses, Troubled Debt Restructuring, Policy	TDRs may be restructured more than once. Among other requirements, a subsequent restructuring may be available for a borrower upon the expiration of temporary restructuring terms if the borrower cannot return to regular loan payments. If the borrower is experiencing an income curtailment that temporarily has reduced his/her capacity to repay, such as loss of employment, reduction of hours, non-paid leave or short term disability, a temporary restructuring is considered. If the borrower lacks the capacity to repay the loan at the current terms due to a permanent condition, a permanent restructuring is considered. In evaluating the need for a subsequent restructuring, the borrower’s ability to repay is generally assessed utilizing a debt to income and cash flow analysis. As the economy slowly improves, the need for multiple restructurings has begun to abate. Loans discharged in Chapter 7 bankruptcy are classified as multiple restructurings if the loan's original terms had also been restructured by the Association. Loans restructured in TDRs that are not evaluated based on collateral are separately evaluated for impairment on a loan by loan basis at the time of restructuring and at each subsequent reporting date for as long as they are reported as TDRs. The impairment evaluation is based on the present value of expected future cash flows discounted at the effective interest rate of the original loan. Expected future cash flows include a discount factor representing a potential for default. Valuation allowances are recorded for the excess of the recorded investments over the result of the cash flow analysis. Loans discharged in Chapter 7 bankruptcy are reported as TDRs and also evaluated based on the present value of expected future cash flows unless evaluated based on collateral. We evaluate these loans using the expected future cash flows because we expect the borrower, not liquidation of the collateral, to be the source of repayment for the loan. Other consumer loans are not considered for restructuring. A loan restructured in a TDR is classified as an impaired loan for a minimum of one year. After one year, that loan may be reclassified out of the balance of impaired loans if the loan was restructured to yield a market rate for loans of similar credit risk at the time of restructuring and the loan is not impaired based on the terms of the restructuring agreement.
Fair Value, Transfer, Policy	Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date under current market conditions and a fair value framework is established whereby assets and liabilities measured at fair value are grouped into three levels of a fair value hierarchy, based on the transparency of inputs and the reliability of assumptions used to estimate fair value. The Company’s policy is to recognize transfers between levels of the hierarchy as of the end of the reporting period in which the transfer occurs. The three levels of inputs are defined as follows: Level 1 – quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 – quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets with few transactions, or model-based valuation techniques using assumptions that are observable in the market. Level 3 – a company’s own assumptions about how market participants would price an asset or liability.
Recent Accounting Pronouncements, Policy	RECENT ACCOUNTING PRONOUNCEMENTS A dopted during the quarter ended December 31, 2016 In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for share-based payment transactions, including accounting for income taxes, forfeitures, and classification in the statement of cash flows.

Early adoption is permitted. The Company is currently evaluating the impact that this accounting guidance may have on its financial condition and results of operations. In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815), Effects of Derivative Contract Novations on Existing Hedge Accounting Relationships. This amendment clarifies that a change in counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedging accounting criteria continue to be met. This accounting guidance will be effective for financial statements issued for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), that revises the criteria for determining when to recognize revenue from contracts with customers and expands disclosure requirements. This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. In August 2015, the FASB issued ASU 2015-14 which defers the effective date of ASU 2014-09 by one year, annual reporting periods and interim period within those annual periods beginning after December 15, 2017. Additionally, the FASB has recently issued and proposed updates to certain aspects of the guidance. The Company's preliminary analysis suggests that the adoption of this accounting guidance is not expected to have a material effect on its financial condition and results of operations.
