Basis Of Presentation [Abstract]
Basis of Presentation	Note 1 – Basis of Presentation
	The consolidated financial statements of Malvern Bancorp, Inc. (the “Company” or “Malvern Bancorp”) include the accounts of the Company and its wholly-owned subsidiary, Malvern Federal Savings Bank (“Malvern Federal Savings” or the “Bank”) and the Bank’s subsidiary, Strategic Asset Management Group, Inc. All significant intercompany accounts and transactions have been eliminated from the accompanying consolidated financial statements.
	The Bank is a federally chartered stock savings bank which was originally organized in 1887. The Bank operates from its headquarters in Paoli, Pennsylvania and through its seven full service financial center offices in Chester and Delaware Counties, Pennsylvania.
	In preparing the consolidated financial statements, management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the consolidated statements of condition and that affect the results of operations for the periods presented. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to change in the near term relate to the determination of the allowance for loan losses, other real estate owned, the evaluation of deferred tax assets and the other-than-temporary impairment evaluation of securities.
	The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”).

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncement	Note 2 – Recent Accounting Pronouncements
	In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-05, “Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” This ASU provides guidance to customer about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. ASU No. 2015-05 is effective for interim and annual reporting periods beginning after December 15, 2015. The Company has evaluated the provisions of ASU No. 2015-05 and has determined that the new standard has no material impact on the Company’s Consolidated Financial Statements.
	In April 2015, the FASB issued ASU No. 2015-04, “Compensation—Retirement Benefits (Topic 715): Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets.” The FASB is issuing the amendments in this Update as part of its initiative to reduce complexity in accounting standards (the Simplification Initiative). The objective of the Simplification Initiative is to identify, evaluate, and improve areas of generally accepted accounting principles (GAAP) for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. ASU No. 2015-01 is effective for interim and annual reporting periods beginning after December 15, 2015. The Company has evaluated the provisions of ASU No. 2015-05 and has determined that the new standard has no material on the Company’s Consolidated Financial Statements.
	In April 2015, the FASB issued ASU No. 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” This ASU requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. The amendments in ASU 2015-03 are effective for public business entities, for fiscal years, and interim periods within those fiscal years beginning after December 15, 2015. Early adoption is permitted. This amendment should be applied on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. Upon transition, an entity is required to comply with the applicable disclosures for a change in an accounting principle. These disclosures include the nature of and reason for the change in accounting principle, the transition method, a description of the prior-period information that has been retrospectively adjusted, and the effect of the change on the financial statement line items (i.e., debt issuance cost asset and the debt liability). The Company is currently evaluating the provisions of ASU No. 2015-03 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements.
	In January 2015, the FASB issued ASU 2015-01, “Income Statement — Extraordinary and Unusual Items (Subtopic 225-20)”. This Update eliminates from GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement—Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. Paragraph 225-20-45-2 contains the following criteria that must both be met for extraordinary classification, (1) unusual nature - the underlying event or transaction should possess a high degree of abnormality and be of a type clearly unrelated to, or only incidentally related to, the ordinary and typical activities of the entity, taking into account the environment in which the entity operates; and (2) infrequency of occurrence - the underlying event or transaction should be of a type that would not reasonably be expected to recur in the foreseeable future, taking into account the environment in which the entity operates. The amendments in ASU 2015-01 are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s financial statements.

Earnings Per Share [Abstract]
Earnings Per Share	Note 3 – Earnings Per Share
	Basic earnings per common share is computed based on the weighted average number of shares outstanding reduced by unearned ESOP shares. Diluted earnings per share is computed based on the weighted average number of shares outstanding and common stock equivalents (“CSEs”) that would arise from the exercise of dilutive securities reduced by unearned ESOP shares. As of March 31, 2015 and for the three and six months ended March 31, 2015 and 2014 the Company had not issued and did not have any outstanding CSEs and, at the present time, the Company’s capital structure has no potential dilutive securities.
	The following table sets forth the composition of the weighted average shares (denominator) used in the earnings per share computations.

Employee Stock Ownership Plan [Abstract]
Employee Stock Ownership Plan	Note 4 – Employee Stock Ownership Plan
	The Company established an employee stock ownership plan (“ESOP”) for substantially all of its full-time employees. The current ESOP trustee is Pentegra. Shares of the Company’s common stock purchased by the ESOP are held until released for allocation to participants. Shares released are allocated to each eligible participant based on the ratio of each such participant’s base compensation to the total base compensation of all eligible plan participants. As the unearned shares are committed to be released and allocated among participants, the Company recognizes compensation expense equal to the fair value of the ESOP shares during the periods in which they become committed to be released. To the extent that the fair value of the ESOP shares released differs from the cost of such shares, the difference is charged or credited to additional paid-in capital. During the period from May 20, 2008 to September 30, 2008, the ESOP purchased 241,178 shares of the common stock for approximately $2.6 million, an average price of $10.86 per share, which was funded by a loan from Malvern Federal Bancorp, Inc. (the Company’s predecessor). The ESOP loan is being repaid principally from the Bank’s contributions to the ESOP. The loan, which bears an interest rate of 5%, is being repaid in quarterly installments through 2026. Shares are released to participants proportionately as the loan is repaid. During the three and six months ended March 31, 2015 and 2014, there were 3,600 and 7,200 shares, respectively, committed to be released. At March 31, 2015, there were 165,165 unallocated shares and 94,053 allocated shares held by the ESOP which had an aggregate fair value of approximately $2.2 million.

Investment Securities [Abstract]
Investment Securities	Note 5 - Investment Securities
	The Company’s investment securities are classified as available-for-sale or held-to-maturity at March 31, 2015 and available-for-sale at September 30, 2014. Investment securities available-for-sale are reported at fair value with unrealized gains or losses included in equity, net of tax. Accordingly, the carrying value of such securities reflects their fair value at the balance sheet date. Fair value is based upon either quoted market prices, or in certain cases where there is limited activity in the market for a particular instrument, assumptions are made to determine their fair value.
	Transfers of debt securities from the available-for-sale category to the held-to-maturity category are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer remains in accumulated other comprehensive income and in the carrying value of the held-to-maturity investment security. Premiums or discounts on investment securities are amortized or accreted using the effective interest method over the life of the security as an adjustment of yield. Unrealized holding gains or losses that remain in accumulated other comprehensive income are amortized or accreted over the remaining life of the security as an adjustment of yield, offsetting the related amortization of the premium or accretion of the discount.
	The following tables present information related to the Company’s investment securities at March 31, 2015 and September 30, 2014. At September 30, 2014 there were no held-to-maturity investment securities.

	During the six months ended March 31, 2015, the Company transferred at fair value approximately $47.4 million in available-for-sale investment securities to the held-to-maturity category. The net unrealized loss at date of transfer amounted to $33,000, remained in accumulated other comprehensive income and will be discounted over the remaining life of the securities as an adjustment of yield, offsetting the related amortization of the premium or accretion of the discount on the transferred securities. No gains or losses were recognized at the time of transfer. Management considers the held-to-maturity classification of these investment securities to be appropriate as the Company has the positive intent and ability to hold these securities to maturity.
	For the six months ended March 31, 2015, proceeds of available-for-sale investment securities sold amounted to approximately $51.2 million. Gross realized gains on investment securities sold amounted to approximately $386,000, while gross realized losses amounted to approximately $94,000, for the period. For the six months ended March 31, 2014, proceeds of investment securities sold amounted to approximately $824,000. Gross realized gains on investment securities sold amounted to approximately $14,000, while there were no gross realized losses, for the period.
	The varying amount of sales from the available-for-sale portfolio over the past few years, reflect the significant volatility present in the market. Given the historic low interest rates prevalent in the market, it is necessary for the Company to protect itself from interest rate exposure. Securities that once appeared to be sound investments can, after changes in the market, become securities that the Company has the flexibility to sell to avoid losses and mismatches of interest-earning assets and interest-bearing liabilities at a later time.
	The following tables indicate gross unrealized losses not recognized in income and fair value, aggregated by investment category and the length of time individual securities have been in a continuous unrealized loss position at March 31, 2015 and September 30, 2014:

As of March 31, 2015, the estimated fair value of the securities disclosed above was primarily dependent upon the movement in market interest rates, particularly given the negligible inherent credit risk associated with these securities. These investment securities are comprised of securities that are rated investment grade by at least one bond credit rating service. Although the fair value will fluctuate as the market interest rates move, management believes that these fair values will recover as the underlying portfolios mature and are reinvested in market rate yielding investments. As of March 31, 2015, the Company held 14 U.S. government agency securities, 11 tax-free municipal bonds, 13 corporate securities, 38 mortgage-backed securities and one single issuer trust preferred security which were in an unrealized loss position. The Company does not intend to sell and expects that it is not more likely than not that it will be required to sell these securities until such time as the value recovers or the securities mature. Management does not believe any individual unrealized loss as of March 31, 2015 represents other-than-temporary impairment.
At March 31, 2015 and September 30, 2014 the Company had no securities pledged to secure public deposits.
The following table presents information for investment securities at March 31, 2015, based on scheduled maturities. Actual maturities can be expected to differ from scheduled maturities due to prepayment or early call options of the issuer.

Under the Bank’s loan policy, once a loan has been placed on non-accrual status, we do not resume interest accruals until the loan has been brought current and has maintained a current payment status for not less than six consecutive months. Interest income that would have been recognized on nonaccrual loans had they been current in accordance with their original terms was $39,000 and $32,000 for the three months ended March 31, 2015 and 2014, respectively, and was $63,000 and $75,000 for the six months ended March 31, 2015 and 2014, respectively. There were no loans past due 90 days or more and still accruing interest at March 31, 2015 or September 30, 2014.
Management further monitors the performance and credit quality of the loan portfolio by analyzing the age of the portfolio as determined by whether a loan payment is “current,” that is, it is received from a borrower by the scheduled due date, or the length of time a scheduled payment is past due. The following table presents the classes of the loan portfolio summarized by the aging categories as of March 31, 2015 and September 30, 2014.

Restructured loans deemed to be TDRs are typically the result of extension of the loan maturity date or a reduction of the interest rate of the loan to a rate that is below market, a combination of rate and maturity extension, or by other means including covenant modifications, forbearance and other concessions. However, the Company generally only restructures loans by modifying the payment structure to require payments of interest only for a specified period or by reducing the actual interest rate. Once a loan becomes a TDR, it will continue to be reported as a TDR during the term of the restructure.
The Company had two and three loans classified as TDRs with an aggregate outstanding balance of $130,000 and $1.1 million at March 31, 2015 and September 30, 2014, respectively. The two TDR loans at March 31, 2015 were also classified as impaired; however, they were performing prior to the restructure and all except one loan, continued to perform under their restructured terms through March 31, 2015, and, accordingly, were deemed to be performing loans at March 31, 2015 and we continued to accrue interest on such loans through such date. At March 31, 2015, one construction and development TDR loan with a balance of $21,000 was deemed a non-accruing TDR and was also deemed impaired at March 31, 2015. At September 30, 2014, three loans deemed TDRs with an aggregate balance of $1.1 million were classified as impaired; however, they were performing prior to the restructure and continued to perform under their restructured terms as of September 30, 2014, and, accordingly, were deemed to be performing loans at September 30, 2014 and we continued to accrue interest on such loans through such date. At September 30, 2014, one construction and development TDR loan with a balance of $78,000 was deemed a non-accruing TDR and was also deemed impaired at September 30, 2014. All of such loans have been classified as TDRs since we modified the payment terms and in some cases interest rate from the original agreements and allowed the borrowers, who were experiencing financial difficulty, to make interest only payments for a period of time in order to relieve some of their overall cash flow burden. Some loan modifications classified as TDRs may not ultimately result in the full collection of principal and interest, as modified, and result in potential incremental losses. These potential incremental losses have been factored into our overall estimate of the allowance for loan losses. The level of any defaults will likely be affected by future economic conditions. A default on a troubled debt restructured loan for purposes of this disclosure occurs when the borrower is 90 days past due or a foreclosure or repossession of the applicable collateral has occurred.

Regulatory Matters [Abstract]
Regulatory Matters	Note 7 - Regulatory Matters
	The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk-weightings and other factors.
	In July of 2013, the respective U.S. federal banking agencies issued final rules implementing Basel III and the Dodd-Frank Act capital requirements to be fully phased in on a global basis on January 1, 2019. The new regulations establish a new tangible common equity capital requirement, increase the minimum requirement for the current Tier 1 risk-weighted asset (“RWA”) ratio, phase out certain kinds of intangibles treated as capital and certain types of instruments and change the risk weightings of certain assets used to determine required capital ratios. The new common equity Tier 1 capital component requires capital of the highest quality — predominantly composed of retained earnings and common stock instruments. For community banks such as Malvern Federal Savings Bank, a common equity Tier 1 capital ratio 4.5% became effective on January 1, 2015. The new capital rules also increased the current minimum Tier 1 capital ratio from 4.0% to 6.0% beginning on January 1, 2015. In addition, institutions that seek the freedom to make capital distributions and pay discretionary bonuses to executive officers without restriction must also maintain greater than 2.5% in common equity attributable to a capital conservation buffer to be phased in from January 1, 2016 until January 1, 2019. The new rules also increase the risk weights for several categories of assets, including an increase from 100% to 150% for certain acquisition, development and construction loans and more than 90-day past due exposures. The new capital rules maintain the general structure of the prompt corrective action rules, but incorporate the new common equity Tier 1 capital requirement and the increased Tier 1 RWA requirement into the prompt corrective action framework.
	The Bank remains well capitalized under the implementation of Basel III, which was effective January 1, 2015.
	Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of tangible and core capital (as defined in the regulations) to total adjusted tangible assets (as defined) and of risk-based capital (as defined) to risk-weighted assets (as defined). In addition to the standard regulatory capital requirements, the Bank also is required to satisfy individual minimum capital ratios (“IMCRs”) imposed by the Office of the Comptroller of the Currency of 8.5% Tier 1 capital to adjusted total assets, 10.5% Tier 1 risk-based capital to risk-weighted assets and 12.5% total risk-based capital to risk-weighted assets.
	Management believes, as of March 31, 2015, that the Bank met all capital adequacy requirements to which it was subject.
	The Bank’s actual capital amounts and ratios are also presented in the table:

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 8 - Fair Value Measurements
	The Company follows FASB ASC Topic 820 “Fair Value Measurement,” to record fair value adjustments to certain assets and to determine fair value disclosures for the Company’s financial instruments. Investment and mortgage-backed securities available-for-sale are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as impaired loans, real estate owned and certain other assets. These nonrecurring fair value adjustments typically involve application of lower-of-cost-or-market accounting or write-downs of individual assets.
	The Company groups its assets at fair value in three levels, based on the markets in which the assets are traded and the reliability of the assumptions used to determine fair value. These levels are:
	Level 1—Valuation is based upon quoted prices for identical instruments traded in active markets.
	Level 2—Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.
	Level 3—Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset.
	The Company bases its fair values on 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. It is our policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements, in accordance with the fair value hierarchy.
	Fair value measurements for assets where there exists limited or no observable market data and, therefore, are based primarily upon the Company’s or other third-party’s estimates, are often calculated based on the characteristics of the asset, the economic and competitive environment and other factors. Therefore, the results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset. Additionally, there may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future valuations.
	FASB ASC Topic 825 “Financial Instruments” provides an option to elect fair value as an alternative measurement for selected financial assets and financial liabilities not previously recorded at fair value. The fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation.
	The Company monitors and evaluates available data to perform fair value measurements on an ongoing basis and recognizes transfers among the levels of the fair value hierarchy as of the date event or a change in circumstances that affects the valuation method chosen. There were no changes in valuation technique or transfers between levels at March 31, 2015 and September 30, 2014.

The following disclosure of the estimated fair value of financial instruments is made in accordance with the requirements of FASB ASC 825. The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methods. However, considerable judgment is necessarily 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 would 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. FASB ASC 825 excludes certain financial instruments and all non-financial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.
The fair value estimates presented herein are based on pertinent information available to management as of March 31, 2015 and September 30, 2014. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since March 31, 2015 and September 30, 2014 and, therefore, current estimates of fair value may differ significantly from the amounts presented herein
The following assumptions were used to estimate the fair value of the Company’s financial instruments:
Cash and Cash Equivalents. These assets are carried at historical cost. The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the instrument and its expected realization.
Investment Securities Available-for-Sale. Investment and mortgage-backed securities available-for-sale (carried at fair value) are measured at fair value on a recurring basis. Fair value measurements for these securities are typically obtained from independent pricing services that we have engaged for this purpose. When available, we, or our independent pricing service, use quoted market prices to measure fair value. If market prices are not available, fair value measurement is based upon models that incorporate available trade, bid and other market information and for structured securities, cash flow and, when available, loan performance data. Because many fixed income securities do not trade on a daily basis, our independent pricing service’s applications apply available information through processes such as benchmark curves, benchmarking of like securities, sector groupings and matrix pricing to prepare evaluations. For each asset class, pricing applications and models are based on information from market sources and integrate relevant credit information. All of our securities are valued using either of the foregoing methodologies to determine fair value adjustments recorded to our financial statements. The Company had no Level 1 or Level 3 securities as of March 31, 2015 or September 30, 2014.
Investment Securities Held-to-Maturity. The fair value of investment securities held-to-maturity was primarily measured using information from a third-party pricing service. If quoted prices were not available, fair values were estimated primarily by obtaining quoted prices for similar assets in active markets or through the use of pricing models. In cases where there may be limited or less transparent information provided by the third-party pricing service, fair value may be estimated by the use of secondary pricing services or through the use of non-binding third-party broker quotes.
Loans Receivable. We do not record loans at fair value on a recurring basis. As such, valuation techniques discussed herein for loans are primarily for estimating fair value for FASB ASC 825 disclosure purposes. However, from time to time, we record nonrecurring fair value adjustments to loans to reflect partial write-downs for impairment or the full charge-off of the loan carrying value. The valuation of impaired loans is discussed below. The fair value estimate for FASB ASC 825 purposes differentiates loans based on their financial characteristics, such as product classification, loan category, pricing features and remaining maturity. Prepayment and credit loss estimates are evaluated by loan type and rate. The fair value of loans is estimated by discounting contractual cash flows using discount rates based on current industry pricing, adjusted for prepayment and credit loss estimates.
Loans Held-For-Sale. The fair values of mortgage loans originated and intended for sale in the secondary market are based on current quoted market prices. There were no loans held for sale at March 31, 2015 or September 30, 2014.
Impaired Loans. Impaired loans are valued utilizing independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments to comparable assets based on the appraisers’ market knowledge and experience. The appraisals are adjusted downward by management, as necessary, for changes in relevant valuation factors subsequent to the appraisal date and are considered level 3 inputs.
Accrued Interest Receivable. This asset is carried at historical cost. The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the instrument and its expected realization.
Restricted Stock. Although restricted stock is an equity interest in the FHLB, it is carried at cost because it does not have a readily determinable fair value as its ownership is restricted and it lacks a market. The estimated fair value approximates the carrying amount.
Other Real Estate Owned. Assets acquired through foreclosure or deed in lieu of foreclosure are recorded at estimated fair value less estimated selling costs when acquired, thus establishing a new cost basis. Fair value is generally based on independent appraisals. These appraisals include adjustments to comparable assets based on the appraisers’ market knowledge and experience, and are considered level 3 inputs. When an asset is acquired, the excess of the loan balance over fair value, less estimated selling costs, is charged to the allowance for loan losses. If the estimated fair value of the asset declines, a write-down is recorded through expense. The valuation of foreclosed assets is subjective in nature and may be adjusted in the future because of, among other factors, changes in the economic conditions.
Deposits. Non-maturity deposit liabilities are carried at cost. As such, valuation techniques discussed herein for these products are primarily for estimating fair value for FASB ASC 825 disclosure purposes. The fair value of non-maturity deposits is discounted based on rates available for borrowings of similar maturities. A decay rate is estimated for non-maturity deposits. The discount rate for non-maturity deposits is adjusted for servicing costs based on industry estimates.
Time deposits are valued using an “all in” cost for brokered CDs with a similar maturity. The rates are further adjusted to offset the “all in” cost against servicing costs based upon industry estimates.
Long-Term Borrowings. Advances from the FHLB are carried at amortized cost. However, we are required to estimate the fair value of long-term debt under FASB ASC 825. The fair value is based on the contractual cash flows discounted using rates currently offered for new notes with similar remaining maturities.
Accrued Interest Payable. This liability is carried at historical cost. The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the instrument and its expected realization.
Commitments to Extend Credit and Letters of Credit. The majority of the Company’s commitments to extend credit and letters of credit carry current market interest rates if converted to loans. Because commitments to extend credit and letters of credit are generally unassignable by either the Bank or the borrower, they only have value to the Company and the borrower. The estimated fair value approximates the recorded deferred fee amounts, which are not significant.
Mortgage Servicing Rights. The fair value of mortgage servicing rights is based on observable market prices when available or the present value of expected future cash flows when not available. Assumptions, such as loan default rates, costs to service, and prepayment speeds significantly affect the estimate of future cash flows. Mortgage servicing rights are carried at the lower of cost or fair value.
The carrying amount and estimated fair value of the Company’s financial instruments as of March 31, 2015 and September 30, 2014 are presented below:
