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. On March 31, 2015, approximately 77% 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 accounting principles generally accepted in the United States of America 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 mortgage loan servicing rights, the valuation of deferred tax assets, and the determination of pension obligations and stock-based compensation 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 March 31, 2015, 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 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, 2014 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, 2015 or for any other period.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE
	Basic earnings per share is the amount of earnings available to each share of common stock outstanding during the reporting period. Diluted earnings per share is the amount of earnings available 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. At March 31, 2015 and 2014, respectively, the ESOP held 6,391,761 and 6,825,100 shares that were neither allocated to participants nor committed to be released to participants.

	The unrealized losses on investment securities were attributable to interest rate increases. 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. At March 31, 2015, the amortized cost and fair value of U.S. government and agency obligations available for sale, categorized as due within one year, are $2,000 and $2,012, respectively. At September 30, 2014, the amortized cost and fair value of those obligations, then categorized as due in more than one year but less than five years, were $2,000 and $2,023, respectively.

	At March 31, 2015 and September 30, 2014, respectively, $1,101 and $4,962 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 March 31, 2015 and September 30, 2014, the percentages of residential real estate loans held in Ohio were 66% and 68%, respectively, and the percentages held in Florida were 17% as of both dates. As of March 31, 2015 and September 30, 2014, home equity loans and lines of credit were concentrated in Ohio (40% at each date), Florida (27% and 28% respectively), and California (13% at each date). Although somewhat dissipating during the last two years, the lingering effects of the adverse economic conditions and market for real estate in Ohio and Florida that arose in connection with the financial crisis of 2008, continue to unfavorably impact the ability of borrowers in those areas to repay their loans.
	Home Today is 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 Core borrowers. Borrowers in the Home Today program must complete financial management education and counseling and must be referred to the Association by a sponsoring organization with which the Association has partnered as part of the program. Borrowers must also meet a minimum credit score threshold. 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. While effective March 27, 2009, the Home Today underwriting guidelines were changed to be substantially the same as the Association’s traditional first mortgage product, the majority of loans in this program were originated prior to that date. As of March 31, 2015 and September 30, 2014, the principal balance of Home Today loans originated prior to March 27, 2009 was $142,410 and $151,164, 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 March 31, 2015 and September 30, 2014 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 net of deferred fees and any applicable loans-in-process.

	Total non-accrual loans	$	122,293			$	135,537
	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. At March 31, 2015 and September 30, 2014, respectively, the recorded investment in non-accrual loans includes $71,448 and $73,946 which are performing according to the terms of their agreement, of which $46,183 and $49,019 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, 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 March 31, 2015 and September 30, 2014 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.

At March 31, 2015 and September 30, 2014, 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. 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 March 31, 2015 and September 30, 2014, respectively, allowances on individually reviewed loans evaluated for impairment based on the present value of cash flows, such as performing TDRs, were $14,560 and $15,787.
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 March 31, 2015 and September 30, 2014, respectively, approximately 37% and 42% 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 through March 31, 2015 paid all claim payments at 67%. In April 2015, the Association was notified that, in addition to a catch-up adjustment for prior claims, all future claims will be paid at 70%. 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 our owned portfolio covered by mortgage insurance provided by PMIC as of March 31, 2015 and September 30, 2014, respectively, was $157,842 and $186,233 of which $145,325 and $170,128 was current. The amount of loans in our owned portfolio covered by mortgage insurance provided by Mortgage Guaranty Insurance Corporation as of March 31, 2015 and September 30, 2014, respectively, was $66,602 and $74,254 of which $65,943 and $73,616 was current. As of March 31, 2015, 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. The state of the economy and low housing prices continue to have an adverse impact on a portion of this portfolio since the home equity lines generally are in a second lien position. Post-origination deterioration in economic and housing market conditions may also 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. When the Association began to offer new home equity lines of credit again, the product was designed with prudent property and credit performance conditions to reduce future risk. 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 80%. Construction financing generally involves greater credit risk than long-term financing on improved, owner-occupied real estate. Risk of loss on a construction loan depends largely upon the accuracy of the initial estimate of the value of the property at completion of construction compared to the estimated cost (including interest) of construction and other assumptions. If the estimate of construction cost proves to be inaccurate, the Association may be required to advance additional funds beyond the amount originally committed in order to protect the value of the property. Moreover, if the estimated value of the completed project proves to be inaccurate, the borrower may hold a property with a value that is insufficient to assure full repayment of the construction loan upon the sale of the property. This is more likely to occur when home prices are falling.
Other consumer loans are comprised of loans secured by certificate of deposit accounts, which are fully recoverable in the event of non-payment.
The recorded investment and the unpaid principal balance of impaired loans, including those reported as TDRs, as of March 31, 2015 and September 30, 2014 are summarized as follows. Balances of recorded investments are net of deferred fees.

At March 31, 2015 and September 30, 2014, respectively, the recorded investment in impaired loans includes $184,307 and $186,428 of loans restructured in TDRs of which $19,010 and $20,851 were 90 days or more past due.
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.
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 greater than 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;
•	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
6/30/14	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
9/30/12	Pursuant to an OCC directive, a loan is considered collateral dependent and any collateral shortfall is charged off when all borrowers obligated on a loan are discharged through Chapter 7 bankruptcy	All
6/30/12	Loans in any form of bankruptcy greater than 30 days past due are considered collateral dependent and any collateral shortfall is charged off	All
12/31/11	Pursuant to an OCC directive, impairment on collateral dependent loans previously reserved for in the allowance were charged off. Charge-offs are recorded to recognize confirmed collateral shortfalls on impaired loans (2)	All
9/30/10	Timing of impairment evaluation was accelerated to include equity loans greater than 90 days delinquent (3)	Home Equity Loans
____________________________
-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. Adoption of this policy did not result in a material change to total charge-offs or the provision for loan losses in the three or nine months ending June 30, 2014.
-2	Prior to 12/31/2011, partial charge-offs were not used, but a reserve in the allowance was established when the recorded investment in the loan exceeded the fair value of the collateral less costs to dispose. Individual loans were only charged off when a triggering event occurred, such as a foreclosure action was culminated, a short sale was approved, or a deed was accepted in lieu of repayment.
-3	Prior to 9/30/2010, impairment evaluations on equity loans were performed when the loan was greater than 180 days delinquent.
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 March 31, 2015 and March 31, 2014.
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.

Interest on loans in non-accrual status is recognized on a cash-basis. The amounts of interest income on impaired loans recognized using a cash-basis method were $306 and $583 for the quarter ended and six months ended March 31, 2015, respectively, and $285 and $629 for the quarter ended and six months ended March 31, 2014, respectively. 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.

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 continues to linger. 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 and six months ended March 31, 2015 and March 31, 2014 (set forth in the table below), the pre-restructured outstanding recorded investment was not materially different from the post-restructured outstanding recorded investment.

Residential loans are internally assigned a grade that complies with the guidelines outlined in the OCC’s Handbook for Rating Credit Risk. Pass loans are assets well protected by the current paying capacity of the borrower. Special Mention loans have a potential weakness 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.
At March 31, 2015 and September 30, 2014, respectively, the recorded investment of impaired loans includes $102,906 and $103,459 of TDRs that are individually evaluated for impairment, but have adequately performed under the terms of the restructuring and are classified as Pass loans. At March 31, 2015 and September 30, 2014, respectively, there were $12,010 and $14,814 of loans classified substandard and $5,879 and $6,084 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 March 31, 2015 and September 30, 2014, no consumer loans were graded as nonperforming.
During the quarter ended December 31, 2013, $5,321 of residential loans were deemed uncollectible and fully charged-off as a result of implementing a new practice of charging off the remaining balance on loans that had remained delinquent and in the foreclosure process for greater than 1,500 days. These loans previously were recorded at estimated net realizable value, with the potential for additional loss recognized within the allowance for loan losses. Any future foreclosure proceeds on these loans would result in recoveries of prior charge-offs.
Activity in the allowance for loan losses is summarized as follows:

	The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and in various state and city jurisdictions. Federal income tax returns and the Association's Ohio Franchise Tax returns have been audited and settled for tax years through 2010 and 2011, respectively. With few exceptions, the Company is no longer subject to federal or state tax examinations for tax years prior to 2011.
	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 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 balance of these investments is included in Other Assets on the Consolidated Statements of Condition, $994 at March 31, 2015 and $0 at September 30, 2014.
	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 and six months ended March 31, 2015 and March 31, 2014.

	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, including an estimated settlement adjustment due to expected lump sum payments exceeding the interest cost for the year, of net periodic cost recognized in the statements of income are as follows:

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 5 to 10 years following the date that the line of credit was established, subject to various conditions, including compliance with payment obligation, 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 March 31, 2015, the Company had commitments to originate loans as follows:
	Fixed-rate mortgage loans	$	295,960
	Adjustable-rate mortgage loans	273,605

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 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 March 31, 2015 and September 30, 2014, respectively, there were $1,101 and $4,570 loans held for sale, with unpaid principal balances of $1,111 and $4,491, subject to pending agency contracts for which the fair value option was elected. Included in the net gain on the sale of loans is $0 and $37 for the three months ending March 31, 2015 and 2014, respectively, and $(111) and $(53) for the six months ending March 31, 2015 and 2014, respectively, related to changes during the period in the fair value of loans held for sale subject to pending agency contracts.
	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 March 31, 2015 and September 30, 2014, respectively, this includes $586,091 and $568,868 of investments in U.S. government and agency obligations including U.S. Treasury notes and sequentially structured, 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 treasury notes and 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 March 31, 2015 and September 30, 2014 there were $1,101 and $4,570, respectively, of loans held for sale measured at fair value and $0 and $392, respectively, of loans held for sale carried at cost.
	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 observable market price of the loan or the fair value of the collateral less estimated costs to dispose. Impairment is measured using the 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. To calculate impairment of collateral-dependent loans, the fair market values of the collateral, estimated using exterior appraisals in the majority of instances, are reduced by calculated costs to dispose derived from historical experience and recent market conditions. Any indicated impairment is recognized by a charge to the allowance for loan losses. Subsequent increases in collateral values or principal pay downs on loans with recognized impairment could result in an impaired loan being carried below its fair value. When no impairment loss is indicated, the carrying amount is considered to approximate the fair value of that loan to the Company because contractually that is the maximum recovery the Company can expect. The recorded investment of loans individually evaluated for impairment based on the fair value of the collateral are included in Level 3 of the hierarchy with assets measured at fair value on a non-recurring basis. The range and weighted average impact of costs to dispose on fair values is determined at the time of impairment or when additional impairment is recognized and is included in quantitative information about significant unobservable inputs later in this note.
	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 March 31, 2015 and September 30, 2014, respectively, this included $103,963 and $105,954 in recorded investment of TDRs with related allowances for loss of $14,560 and $15,787.
	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 March 31, 2015 and September 30, 2014, these adjustments were not significant to reported fair values. At March 31, 2015 and September 30, 2014, respectively, $15,503 and $17,970 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 $1,813 and $1,667 related to properties measured at fair value and $6,588 and $5,465 of properties carried at their original or adjusted cost basis at March 31, 2015 and September 30, 2014, respectively.
	Derivatives—Derivative instruments include interest rate locks on commitments to originate loans for the held for sale portfolio and forward commitments on contracts to deliver mortgage loans. Derivatives 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. Fair value 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 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 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 March 31, 2015 and September 30, 2014 are summarized below. There were no liabilities carried at fair value on a recurring basis at March 31, 2015.

The following table presents the estimated fair value of the Company’s financial instruments. The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret market data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

Presented below is a discussion of the valuation techniques and inputs used by the Company to estimate fair value.
Cash and Due from Banks, Interest Earning Cash Equivalents— 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.
Private Equity Investments— Private equity investments are initially valued based upon transaction price. The carrying value is subsequently adjusted when it is considered necessary based on current performance and market conditions. The carrying values are adjusted to reflect expected exit values. These investments are included in Other Assets in the accompanying Consolidated Statements of Condition at fair value.
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 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. In addition, the Company enters into commitments to originate a portion of its loans, which when funded, are classified as held for sale. Such commitments meet the definition of a derivative and are not designated in a hedging relationship; therefore, gains and losses are recognized immediately in the statement of income. The Company had no derivatives designated as hedging instruments under FASB ASC 815, “Derivatives and Hedging,” at March 31, 2015 or September 30, 2014.
	The following table provides the locations within the Consolidated Statements of Condition and the fair values for derivatives not designated as hedging instruments.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS
	Pending as of March 31, 2015
	In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810) Amendments to the Consolidation Analysis. This amendment modifies the consolidation model for reporting legal entities under both the variable interest model and the voting interest model. This ASU will require all legal entities to reevaluate previous consolidation conclusions under the revised model and will be effective for annual periods beginning after December 15, 2015. Early adoption is permitted. 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 Company is currently evaluating the impact of adopting the amendments on its consolidated financial statements.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), affecting 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. ASC Topic 606 does not apply to rights or obligations associated with financial instruments. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The amendments in this update become effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. The Company is currently evaluating the impact of adopting the amendments on its consolidated financial statements.
	In January 2014, the FASB issued ASU 2014-04, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40), Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure to reduce diversity by clarifying when an in-substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The only impact of these amendments on the Company's consolidated financial statements will be an addition of the disclosure of loans in foreclosure in the Loans and Allowance for Loan Loss footnote.
	Adopted in quarter ended March 31, 2015
	FASB ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects, which was issued in January 2014, permits entities to make an accounting policy election to account for investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statements as a component of income tax expense or benefit. The Company early adopted the amendments in ASC 323-740 related to investments in Qualified Affordable Housing Projects for the quarter ended March 31, 2015, to utilize the proportional amortization method for a recent tax credit investment. The adoption of ASU 2014-01 did not have a material impact on the Company's consolidated financial statements. Related disclosures are included in Note 7. Income Taxes.
	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. On March 31, 2015, approximately 77% 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 accounting principles generally accepted in the United States of America 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 mortgage loan servicing rights, the valuation of deferred tax assets, and the determination of pension obligations and stock-based compensation 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 March 31, 2015, 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 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, 2014 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, 2015 or for any other period.
Loans and Allowance for Loan Losses, Nonaccrual Loan Status, Charge-off & Past Due, Policy	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 greater than 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;
	•	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
	6/30/14	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
	9/30/12	Pursuant to an OCC directive, a loan is considered collateral dependent and any collateral shortfall is charged off when all borrowers obligated on a loan are discharged through Chapter 7 bankruptcy	All
	6/30/12	Loans in any form of bankruptcy greater than 30 days past due are considered collateral dependent and any collateral shortfall is charged off	All
	12/31/11	Pursuant to an OCC directive, impairment on collateral dependent loans previously reserved for in the allowance were charged off. Charge-offs are recorded to recognize confirmed collateral shortfalls on impaired loans (2)	All
	9/30/10	Timing of impairment evaluation was accelerated to include equity loans greater than 90 days delinquent (3)	Home Equity Loans
	____________________________
	-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. Adoption of this policy did not result in a material change to total charge-offs or the provision for loan losses in the three or nine months ending June 30, 2014.
	-2	Prior to 12/31/2011, partial charge-offs were not used, but a reserve in the allowance was established when the recorded investment in the loan exceeded the fair value of the collateral less costs to dispose. Individual loans were only charged off when a triggering event occurred, such as a foreclosure action was culminated, a short sale was approved, or a deed was accepted in lieu of repayment.
	-3	Prior to 9/30/2010, impairment evaluations on equity loans were performed when the loan was greater than 180 days delinquent.
	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.
	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, 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 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	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.
	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 continues to linger. Loans discharged in Chapter 7 bankruptcy are classified as multiple restructurings if the loan's original terms had also been restructured by the Association.
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 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	Pending as of March 31, 2015
	In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810) Amendments to the Consolidation Analysis. This amendment modifies the consolidation model for reporting legal entities under both the variable interest model and the voting interest model. This ASU will require all legal entities to reevaluate previous consolidation conclusions under the revised model and will be effective for annual periods beginning after December 15, 2015. Early adoption is permitted. 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 Company is currently evaluating the impact of adopting the amendments on its consolidated financial statements.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), affecting 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. ASC Topic 606 does not apply to rights or obligations associated with financial instruments. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The amendments in this update become effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. The Company is currently evaluating the impact of adopting the amendments on its consolidated financial statements.
	In January 2014, the FASB issued ASU 2014-04, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40), Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure to reduce diversity by clarifying when an in-substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The only impact of these amendments on the Company's consolidated financial statements will be an addition of the disclosure of loans in foreclosure in the Loans and Allowance for Loan Loss footnote.
	Adopted in quarter ended March 31, 2015
	FASB ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects, which was issued in January 2014, permits entities to make an accounting policy election to account for investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statements as a component of income tax expense or benefit. The Company early adopted the amendments in ASC 323-740 related to investments in Qualified Affordable Housing Projects for the quarter ended March 31, 2015, to utilize the proportional amortization method for a recent tax credit investment. The adoption of ASU 2014-01 did not have a material impact on the Company's consolidated financial statements. Related disclosures are included in Note 7. Income Taxes.
	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.
