Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation - The consolidated financial statements include the accounts of Capitol Federal® Financial, Inc. (the "Company") and its wholly-owned subsidiary, Capitol Federal Savings Bank (the "Bank"). The Bank has a wholly-owned subsidiary, Capitol Funds, Inc. Capitol Funds, Inc. has a wholly-owned subsidiary, Capitol Federal Mortgage Reinsurance Company. All intercompany accounts and transactions have been eliminated in consolidation. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2014, filed with the Securities and Exchange Commission ("SEC"). Interim results are not necessarily indicative of results for a full year.
	Recent Accounting Pronouncements - In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date. The ASU provides recognition, measurement, and disclosure guidance for certain obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. ASU 2013-04 is effective for fiscal years beginning after December 15, 2013, which was October 1, 2014 for the Company, and should be applied retrospectively. The adoption of this ASU did not have a material impact on the Company's consolidated financial condition or result of operations when adopted.
	In January 2014, the FASB issued ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. The ASU revised the conditions that an entity must meet to elect to use the effective yield method when accounting for qualified affordable housing project investments. Per current accounting guidance, an entity that invests in a qualified affordable housing project may elect to account for that investment using the effective yield method if all required conditions are met. For those investments that are not accounted for using the effective yield method, current accounting guidance requires that the investments be accounted for under either the equity method or the cost method. Certain existing conditions required to be met to use the effective yield method are restrictive and thus prevent many such investments from qualifying for the use of the effective yield method. The ASU replaces the effective yield method with the proportional amortization method and modifies the conditions that an entity must meet to be eligible to use a method other than the equity or cost methods to account for qualified affordable housing project investments. If the modified conditions are met, the ASU permits an entity to use the proportional amortization method to amortize the initial cost of the investment in proportion to the amount of tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense. Additionally, the ASU requires new disclosures about all investments in qualified affordable housing projects irrespective of the method used to account for the investments. ASU 2014-01 is effective for fiscal years beginning after December 15, 2014, which is October 1, 2015 for the Company, and should be applied retrospectively. The ASU is not expected to have a material impact on the Company's consolidated financial condition or result of operations when adopted.
	In January 2014, the FASB issued ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The ASU clarifies 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 ASU also requires disclosure of both (1) the amount of foreclosed residential real estate property held by a 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. ASU 2014-04 is effective for fiscal years beginning after December 15, 2014, which is October 1, 2015 for the Company, and can be applied using either a modified retrospective transition method or a prospective transition method. The ASU is not expected to have a material impact on the Company's consolidated financial condition or result of operations when adopted.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The ASU clarifies principles for recognizing revenue and provides a common revenue standard for GAAP and International Financial Reporting Standards. Additionally, the ASU provides implementation guidance on several topics and requires entities to disclose both quantitative and qualitative information regarding contracts with customers. ASU 2014-09 is effective for fiscal years beginning after December 15, 2016, which is October 1, 2017 for the Company, and can be applied using either a retrospective or cumulative-effect transition method. Early adoption is not permitted. The Company has not yet completed its evaluation of this ASU.
	In June 2014, the FASB issued ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The ASU makes limited amendments to the current guidance on accounting for certain repurchase agreements. The ASU also expands disclosure requirements for certain transfers of financial assets accounted for as sales or as secured borrowings. The accounting changes in ASU 2014-11 are effective for the first quarterly period or fiscal year beginning after December 15, 2014, which is January 1, 2015 for the Company, and should be applied using a cumulative-effect transition method. The expanded disclosure requirements for ASU 2014-11 are effective for fiscal years beginning after December 15, 2014, and for quarterly periods beginning after March 15, 2015, which is April 1, 2015 for the Company. The Company accounts for its repurchase agreements as secured borrowings; therefore, the accounting requirements of ASU 2014-11 are not expected to have an impact on its financial condition or results of operations when adopted.

Earnings Per Share	2. EARNINGS PER SHARE
	Shares acquired by the ESOP are not considered in the basic average shares outstanding until the shares are committed for allocation or vested to an employee's individual account. Unvested shares awarded pursuant to the Company's restricted stock benefit plans are treated as participating securities in the computation of EPS pursuant to the two-class method as they contain nonforfeitable rights to dividends. The two-class method is an earnings allocation that determines EPS for each class of common stock and participating security.

	The unrealized losses at December 31, 2014 were primarily a result of an increase in market yields from the time the securities were purchased. In general, as market yields rise, the fair value of securities will decrease; as market yields fall, the fair value of securities will increase. Management generally views changes in fair value caused by changes in interest rates as temporary; therefore, these securities have not been classified as other-than-temporarily impaired. The impairment is also considered temporary because scheduled coupon payments have been made, it is anticipated that the entire principal balance will be collected as scheduled, and management neither intends to sell the securities, nor is it more likely than not that the Company will be required to sell the securities before the recovery of the remaining amortized cost amount, which could be at maturity. As a result of the analysis, management does not believe any other-than-temporary impairments existed at December 31, 2014.
The amortized cost and estimated fair value of debt securities as of December 31, 2014, by contractual maturity, are shown below.  Actual principal repayments may differ from contractual maturities due to prepayment or early call privileges by the issuer.

	Lending Practices and Underwriting Standards - Originating and purchasing one- to four-family loans is the Bank's primary lending business, resulting in a loan concentration in residential first mortgage loans. The Bank purchases one- to four-family loans, on a loan-by-loan basis, from a select group of correspondent lenders, and also originates consumer loans, commercial and multi-family real estate loans, and construction loans secured by residential, multi-family or commercial real estate. As a result of our one- to four-family lending activities, the Bank has a concentration of loans secured by real property located in Kansas and Missouri.
	One- to four-family loans - Full documentation to support an applicant's credit and income, and sufficient funds to cover all applicable fees and reserves at closing, are required on all loans. Loans are underwritten according to the "ability to repay" and "qualified mortgage" standards, as issued by the Consumer Financial Protection Bureau ("CFPB"). Properties securing one- to four-family loans are appraised by either staff appraisers or fee appraisers, both of which are independent of the loan origination function and approved by our Board of Directors.
	The underwriting standards for loans purchased from correspondent and nationwide lenders are generally similar to the Bank's internal underwriting standards. The underwriting of correspondent loans is performed by the Bank's underwriters. For the tables within this Note, correspondent purchased loans are included with originated loans, and bulk purchased loans are reported as purchased loans.
	The Bank also originates construction-to-permanent loans secured by one- to four-family residential real estate. Construction loans are obtained by homeowners who will occupy the property when construction is complete. Construction loans to builders for speculative purposes are not permitted. All construction loans are manually underwritten using the Bank's internal underwriting standards. Construction draw requests and the supporting documentation are reviewed and approved by management. The Bank also performs regular documented inspections of the construction project to ensure the funds are being used for the intended purpose and the project is being completed according to the plans and specifications provided.
	Multi-family and commercial loans - The Bank's multi-family, commercial real estate, and related construction loans are originated by the Bank or are in participation with a lead bank. These loans are granted based on the income producing potential of the property and the financial strength of the borrower and/or guarantor. At the time of origination, loan-to-value ("LTV") ratios on multi-family, commercial real estate, and related construction loans generally cannot exceed 80% of the appraised value of the property securing the loans. The net operating income, which is the income derived from the operation of the property less all operating expenses, must generally be in excess of the required payments related to the outstanding debt at the time of origination. The Bank generally requires personal guarantees from the borrowers covering a portion of the debt in addition to the security property as collateral for these loans. Appraisals on properties securing these loans are performed by independent state certified fee appraisers.
	Consumer loans - The Bank offers a variety of secured consumer loans, including home equity loans and lines of credit, home improvement loans, auto loans, and loans secured by savings deposits. The Bank also originates a very limited amount of unsecured loans. The Bank does not originate any consumer loans on an indirect basis, such as contracts purchased from retailers of goods or services which have extended credit to their customers. The majority of the consumer loan portfolio is comprised of home equity lines of credit for which the Bank also has the first mortgage or the home equity line of credit is in the first lien position.
	The underwriting standards for consumer loans include a determination of an applicant's payment history on other debts and an assessment of an applicant's ability to meet existing obligations and payments on the proposed loan. Although creditworthiness of an applicant is a primary consideration, the underwriting process also includes a comparison of the value of the security in relation to the proposed loan amount.
	Credit Quality Indicators - Based on the Bank's lending emphasis and underwriting standards, management has segmented the loan portfolio into three segments: (1) one- to four-family loans; (2) consumer loans; and (3) multi-family and commercial loans. The one- to four-family and consumer segments are further segmented into classes for purposes of providing disaggregated information about the credit quality of the loan portfolio. The classes are: one- to four-family loans - originated, one- to four-family loans - purchased, consumer loans - home equity, and consumer loans - other.
	The Bank's primary credit quality indicators for the one- to four-family loan and consumer - home equity loan portfolios are delinquency status, asset classifications, LTV ratios, and borrower credit scores. The Bank's primary credit quality indicators for the multi-family and commercial loan and consumer - other loan portfolios are delinquency status and asset classifications.
	The following tables present the recorded investment, by class, in loans 30 to 89 days delinquent, loans 90 or more days delinquent or in foreclosure, total delinquent loans, total current loans, and total recorded investment at the dates presented. The recorded investment in loans is defined as the unpaid principal balance of a loan (net of unadvanced funds related to loans in process), less charge-offs and inclusive of unearned loan fees and deferred costs. At December 31, 2014 and September 30, 2014, all loans 90 or more days delinquent were on nonaccrual status.

	In accordance with the Bank's asset classification policy, management regularly reviews the problem loans in the Bank's portfolio to determine whether any loans require classification. Loan classifications are defined as follows:
	•	Special mention - These loans are performing loans on which known information about the collateral pledged or the possible credit problems of the borrower(s) have caused management to have doubts as to the ability of the borrower(s) to comply with present loan repayment terms and which may result in the future inclusion of such loans in the non-performing loan categories.
	•	Substandard - A loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard loans include those characterized by the distinct possibility the Bank will sustain some loss if the deficiencies are not corrected.
•	Doubtful - Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses present make collection or liquidation in full on the basis of currently existing facts and conditions and values highly questionable and improbable.
•	Loss - Loans classified as loss are considered uncollectible and of such little value that their continuance as assets on the books is not warranted.
The following table sets forth the recorded investment in loans classified as special mention or substandard, by class, at the dates presented. Special mention and substandard loans are included in the formula analysis model if the loan is not individually evaluated for loss. Loans classified as doubtful or loss are individually evaluated for loss. At the dates presented, there were no loans classified as doubtful, and all loans classified as loss were fully charged-off.

The following table shows the weighted average credit score and weighted average LTV for originated and purchased one- to four-family loans and originated consumer home equity loans at the dates presented. Borrower credit scores are intended to provide an indication as to the likelihood that a borrower will repay their debts. Credit scores are updated at least semiannually, with the last update in September 2014, from a nationally recognized consumer rating agency. The LTV ratios provide an estimate of the extent to which the Bank may incur a loss on any given loan that may go into foreclosure. The LTV ratios were based on the current loan balance and either the lesser of the purchase price or original appraisal, or the most recent Bank appraisal, if available. In most cases, the most recent appraisal was obtained at the time of origination.

Fair Value Of Financial Instruments	3 Months Ended
	Dec. 31, 2014
Fair Value Disclosures [Abstract]
Fair Value Of Financial Instruments	5. FAIR VALUE OF FINANCIAL INSTRUMENTS
	Fair Value Measurements – The Company uses fair value measurements to record fair value adjustments to certain assets and to determine fair value disclosures in accordance with Accounting Standards Codification ("ASC") 820 and ASC 825. The Company did not have any liabilities that were measured at fair value at December 31, 2014 or September 30, 2014. The Company's AFS securities 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 or liabilities on a non-recurring basis, such as OREO and loans individually evaluated for impairment. These non-recurring fair value adjustments involve the application of lower-of-cost-or-fair value 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 or liability. Valuation techniques include the use of option pricing models, discounted cash flow models, and similar techniques. The results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset or liability.
	The Company bases its fair values on the price that would be received from the sale of an asset in an orderly transaction between market participants at the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value.
	The following is a description of valuation methodologies used for assets measured at fair value on a recurring basis.
	AFS Securities - The Company's AFS securities portfolio is carried at estimated fair value, with any unrealized gains and losses, net of taxes, reported as AOCI in stockholders' equity. The majority of the securities within the AFS portfolio were issued by GSEs. The Company primarily uses prices obtained from third party pricing services to determine the fair value of its securities. On a quarterly basis, management corroborates a sample of prices obtained from the third party pricing service for Level 2 securities by comparing them to an independent source. If the price provided by the independent source varies by more than a predetermined percentage from the price received from the third party pricing service, then the variance is researched by management. The Company did not have to adjust prices obtained from the third party pricing service when determining the fair value of its securities during the three months ended December 31, 2014 and fiscal year 2014. The Company's major security types, based on the nature and risks of the securities, are:
	•	GSE Debentures - Estimated fair values are based on a discounted cash flow method. Cash flows are determined by taking any embedded options into consideration and are discounted using current market yields for similar securities. (Level 2)
	•	MBS - Estimated fair values are based on a discounted cash flow method. Cash flows are determined based on prepayment projections of the underlying mortgages and are discounted using current market yields for benchmark securities. (Level 2)
	•	Municipal Bonds - Estimated fair values are based on a discounted cash flow method. Cash flows are determined by taking any embedded options into consideration and are discounted using current market yields for securities with similar credit profiles. (Level 2)
	•	Trust Preferred Securities - Estimated fair values are based on a discounted cash flow method. Cash flows are determined by taking prepayment and underlying credit considerations into account. The discount rates are derived from secondary trades and bid/offer prices. (Level 3)

	-1	The Company's Level 3 AFS securities had no activity during the three months ended December 31, 2014, except for principal repayments of $26 thousand and increases in net unrealized losses recognized in other comprehensive income. Increases in net unrealized losses included in other comprehensive income for the three months ended December 31, 2014 were $51 thousand.
	-2	The Company's Level 3 AFS securities had no activity during the year ended September 30, 2014, except for principal repayments of $150 thousand and increases in net unrealized losses recognized in other comprehensive income. Increases in net unrealized losses included in other comprehensive income for the year ended September 30, 2014 were $16 thousand.
	The following is a description of valuation methodologies used for significant assets measured at fair value on a non-recurring basis.
	Loans Receivable – The balance of loans individually evaluated for impairment at December 31, 2014 and September 30, 2014 was $26.4 million and $26.8 million, respectively. Substantially all of these loans were secured by residential real estate and were individually evaluated to ensure that the carrying value of the loan was not in excess of the estimated fair value of the collateral, less estimated selling costs. When no impairment is indicated, the carrying amount is considered to approximate fair value. Fair values were estimated through current appraisals or analyzed based on market indicators. Fair values may be adjusted by management to reflect current economic and market conditions and, as such, are classified as Level 3. Based on this evaluation, the Bank charged-off any loss amounts as of December 31, 2014 and September 30, 2014; therefore, there was no ACL related to these loans.
	OREO – OREO primarily represents real estate acquired as a result of foreclosure or by deed in lieu of foreclosure and is carried at lower-of-cost or fair value. Fair value is estimated through current appraisals or listing prices, less estimated selling costs. As these properties are actively marketed, estimated fair values may be adjusted by management to reflect current economic and market conditions and, as such, are classified as Level 3. The fair value of OREO at December 31, 2014 and September 30, 2014 was $4.5 million and $4.1 million, respectively.
	The following tables provide the level of valuation assumptions used to determine the carrying value of the Company's assets measured at fair value on a non-recurring basis at the dates presented.

	Fair Value Disclosures – The Company determined estimated fair value amounts using available market information and from a variety of valuation methodologies. However, considerable judgment is required to interpret market data to develop the estimates of fair value. Accordingly, the estimates presented are not necessarily indicative of the amount the Company could realize in a current market exchange. The use of different market assumptions and estimation methodologies may have a material impact on the estimated fair value amounts. The fair value estimates presented herein were based on pertinent information available to management as of the dates presented.
	The carrying amounts and estimated fair values of the Company's financial instruments, at the dates presented, were as follows:

Repurchase agreements	220,000		228,564		220,000		227,539
The following methods and assumptions were used to estimate the fair value of the financial instruments:
Cash and Cash Equivalents - The carrying amounts of cash and cash equivalents are considered to approximate their fair value due to the nature of the financial assets. (Level 1)
HTM Securities - Estimated fair values of securities are based on one of three methods: (1) quoted market prices where available; (2) quoted market prices for similar instruments if quoted market prices are not available; (3) unobservable data that represents the Bank's assumptions about items that market participants would consider in determining fair value where no market data is available. HTM securities are carried at amortized cost. (Level 2)
Loans Receivable - The fair value of one- to four-family mortgages and home equity loans are generally estimated using the present value of expected future cash flows, assuming future prepayments and using discount factors determined by prices obtained from securitization markets, less a discount for the cost of servicing and lack of liquidity. The estimated fair value of the Bank's multi-family, commercial, and consumer loans are based on the expected future cash flows assuming future prepayments and discount factors based on current offering rates. (Level 3)
FHLB stock - The carrying value and estimated fair value of FHLB stock equals cost, which is based on redemption at par value. (Level 1)
Deposits - The estimated fair value of demand deposits, savings, and money market accounts is the amount payable on demand at the reporting date. The estimated fair value of these deposits at December 31, 2014 and September 30, 2014 was $2.18 billion and $2.12 billion, respectively. (Level 1) The fair value of certificates of deposit is estimated by discounting future cash flows using current London Interbank Offered Rates ("LIBOR"). The estimated fair value of certificates of deposit at December 31, 2014 and September 30, 2014 was $2.54 billion and $2.55 billion, respectively. (Level 2)
FHLB borrowings and Repurchase Agreements - The fair value of fixed-maturity borrowed funds is estimated by discounting estimated future cash flows using current offer rates. (Level 2) The carrying value of FHLB line of credit is considered to approximate its fair value due to the nature of the financial liability. (Level 1)

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation - The consolidated financial statements include the accounts of Capitol Federal® Financial, Inc. (the "Company") and its wholly-owned subsidiary, Capitol Federal Savings Bank (the "Bank"). The Bank has a wholly-owned subsidiary, Capitol Funds, Inc. Capitol Funds, Inc. has a wholly-owned subsidiary, Capitol Federal Mortgage Reinsurance Company. All intercompany accounts and transactions have been eliminated in consolidation. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2014, filed with the Securities and Exchange Commission ("SEC"). Interim results are not necessarily indicative of results for a full year.
Recent Accounting Pronouncements	Recent Accounting Pronouncements - In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date. The ASU provides recognition, measurement, and disclosure guidance for certain obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. ASU 2013-04 is effective for fiscal years beginning after December 15, 2013, which was October 1, 2014 for the Company, and should be applied retrospectively. The adoption of this ASU did not have a material impact on the Company's consolidated financial condition or result of operations when adopted.
	In January 2014, the FASB issued ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. The ASU revised the conditions that an entity must meet to elect to use the effective yield method when accounting for qualified affordable housing project investments. Per current accounting guidance, an entity that invests in a qualified affordable housing project may elect to account for that investment using the effective yield method if all required conditions are met. For those investments that are not accounted for using the effective yield method, current accounting guidance requires that the investments be accounted for under either the equity method or the cost method. Certain existing conditions required to be met to use the effective yield method are restrictive and thus prevent many such investments from qualifying for the use of the effective yield method. The ASU replaces the effective yield method with the proportional amortization method and modifies the conditions that an entity must meet to be eligible to use a method other than the equity or cost methods to account for qualified affordable housing project investments. If the modified conditions are met, the ASU permits an entity to use the proportional amortization method to amortize the initial cost of the investment in proportion to the amount of tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense. Additionally, the ASU requires new disclosures about all investments in qualified affordable housing projects irrespective of the method used to account for the investments. ASU 2014-01 is effective for fiscal years beginning after December 15, 2014, which is October 1, 2015 for the Company, and should be applied retrospectively. The ASU is not expected to have a material impact on the Company's consolidated financial condition or result of operations when adopted.
	In January 2014, the FASB issued ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The ASU clarifies 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 ASU also requires disclosure of both (1) the amount of foreclosed residential real estate property held by a 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. ASU 2014-04 is effective for fiscal years beginning after December 15, 2014, which is October 1, 2015 for the Company, and can be applied using either a modified retrospective transition method or a prospective transition method. The ASU is not expected to have a material impact on the Company's consolidated financial condition or result of operations when adopted.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The ASU clarifies principles for recognizing revenue and provides a common revenue standard for GAAP and International Financial Reporting Standards. Additionally, the ASU provides implementation guidance on several topics and requires entities to disclose both quantitative and qualitative information regarding contracts with customers. ASU 2014-09 is effective for fiscal years beginning after December 15, 2016, which is October 1, 2017 for the Company, and can be applied using either a retrospective or cumulative-effect transition method. Early adoption is not permitted. The Company has not yet completed its evaluation of this ASU.
	In June 2014, the FASB issued ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The ASU makes limited amendments to the current guidance on accounting for certain repurchase agreements. The ASU also expands disclosure requirements for certain transfers of financial assets accounted for as sales or as secured borrowings. The accounting changes in ASU 2014-11 are effective for the first quarterly period or fiscal year beginning after December 15, 2014, which is January 1, 2015 for the Company, and should be applied using a cumulative-effect transition method. The expanded disclosure requirements for ASU 2014-11 are effective for fiscal years beginning after December 15, 2014, and for quarterly periods beginning after March 15, 2015, which is April 1, 2015 for the Company. The Company accounts for its repurchase agreements as secured borrowings; therefore, the accounting requirements of ASU 2014-11 are not expected to have an impact on its financial condition or results of operations when adopted.
