	Summary of Significant Accounting Policies
	Washington Federal, Inc. was formed in 1994 as a Washington corporation headquartered in Seattle, Washington. The Company is a bank holding company that conducts its operations through a federally-insured national bank subsidiary. As used throughout this document, the terms "Washington Federal" or the "Company" refer to Washington Federal, Inc. and its consolidated subsidiaries and the term "Bank" refers to the operating subsidiary Washington Federal, National Association.
	The consolidated unaudited interim financial statements included in this report have been prepared by Washington Federal. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect amounts reported in the financial statements. Actual results could differ from these estimates. In the opinion of management, all adjustments (consisting only of normal recurring accruals) necessary for a fair presentation are reflected in the interim financial statements. The September 30, 2013 Consolidated Statement of Financial Condition was derived from audited financial statements.
	The information included in this Form 10-Q should be read in conjunction with Company’s 2013 Annual Report on Form 10-K (“2013 Form 10-K”) as filed with the SEC. Interim results are not necessarily indicative of results for a full year.
	The significant accounting policies used in preparation of the Company's consolidated financial statements are disclosed in its 2013 Form 10-K. Other than as discussed below, there have not been any material changes in its significant accounting policies compared to those contained in its 2013 Form 10-K.
	Off-Balance-Sheet Credit Exposures – The only material off-balance-sheet credit exposures are loans in process and unused lines of credit, which had a combined balance at March 31, 2014, excluding covered loans, of $545 million. The Company estimates losses on off-balance-sheet credit exposures by including the exposures with the related principal balance outstanding and then applying its general reserve methodology.

Most loans restructured in troubled debt restructurings ("TDRs") are accruing and performing loans where the borrower has proactively approached the Company about modification due to temporary financial difficulties. Each request is individually evaluated for merit and likelihood of success. The concession for these loans is typically a payment reduction through a rate reduction of between 100 to 200 basis points for a specific term, usually six to twenty-four months. Interest-only payments may also be approved during the modification period. As of March 31, 2014, single-family residential loans comprised 86.1% of TDRs.
The Company reserves for restructured loans within its allowance for loan loss methodology by taking into account the following performance indicators: 1) time since modification, 2) current payment status and 3) geographic area.

Receivables [Abstract]	'
Allowance for Losses on Loans	'
	Allowance for Losses on Loans
	The Company has an asset quality review function that analyzes its loan portfolios and reports the results of the review to the Board of Directors on a quarterly basis. The single-family residential, HELOC and consumer portfolios are evaluated based on their performance as a pool of loans, since no single loan is individually significant or judged by its risk rating, size or potential risk of loss. The construction, land, multi-family, commercial real estate and commercial and industrial loans are risk rated on a loan by loan basis to determine the relative risk inherent in specific borrowers or loans. Based on that risk rating, the loans are assigned a grade and classified as follows:
	•	Pass – the credit does not meet one of the definitions below.
	•	Special mention – A special mention credit is considered to be currently protected from loss but is potentially weak. No loss of principal or interest is foreseen; however, proper supervision and Management attention is required to deter further deterioration in the credit. Assets in this category constitute some undue and unwarranted credit risk but not to the point of justifying a risk rating of substandard. The credit risk may be relatively minor yet constitutes an unwarranted risk in light of the circumstances surrounding a specific asset.
	•	Substandard – A substandard credit is an unacceptable credit. Additionally, repayment in the normal course is in jeopardy due to the existence of one or more well defined weaknesses. In these situations, loss of principal is likely if the weakness is not corrected. A substandard asset is inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged, if any. Assets so classified will have a well defined weakness or weaknesses that jeopardize the liquidation of the debt. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets risk rated substandard.
	•	Doubtful – A credit classified doubtful has all the weaknesses inherent in one classified substandard with the added characteristic that the weakness makes collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The probability of loss is high, but because of certain important and reasonably specific pending factors that may work to the advantage and strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral, and refinancing plans.
	•	Loss – Credits classified loss are considered uncollectible and of such little value that their continuance as a bankable asset is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this asset even though partial recovery may be affected in the future. Losses should be taken in the period in which they are identified as uncollectible. Partial charge-off versus full charge-off may be taken if the collateral offers some identifiable protection.
	The following table summarizes the activity in the allowance for loan losses (excluding acquired and covered loans) for the quarter ended March 31, 2014 and fiscal year ended September 30, 2013:

	The Company recorded a $4,336,000 reversal of the provision for loan losses during the quarter ended March 31, 2014, while $0 provision was recorded for the same quarter one year ago. This reversal of the provision for loan losses is comprised of a $4,750,000 reversal for non-covered loans and a provision of $414,000 for acquired or covered loans. The primary reason for the current period recovery is the credit quality of the portfolio has been improving significantly and economic conditions are more favorable.
	Non-performing assets (“NPAs”) amounted to $174,789,000, or 1.22%, of total assets at March 31, 2014, compared to $246,075,000, or 1.88%, of total assets one year ago. Acquired loans, including covered loans, are not initially classified as non-performing loans because, at acquisition, the carrying value of these loans is adjusted to reflect fair value. There was an additional provision for loan losses recorded on acquired or covered loans during the quarter ended March 31, 2014 of $414,000 as a result of decreased expectations of future cash flows due to increased credit losses for certain acquired loan pools. Non-accrual loans decreased from $149,033,000 at March 31, 2013, to $100,198,000 at March 31, 2014, a 32.8% decrease.
	The Company had net recoveries of $1,523,000 for the quarter ended March 31, 2014, compared with $3,943,000 of net charge-offs for the same quarter one year ago. A loan is charged-off when the loss is estimable and it is confirmed that the borrower will not be able to meet its contractual obligations.
	For the period ending March 31, 2014 , $114,096,000 of the allowance was calculated under the Company's general allowance methodology and the remaining $835,000 was made up of specific reserves on loans that were deemed to be impaired. For the period ending September 30, 2013, these amounts were $113,268,000 and $3,473,000, respectively. The shift in total allowance allocation from specific reserves to general reserves is due to the Company having already addressed many of the problem loans focused in the speculative construction and land A&D portfolios, combined with an increase in delinquencies and elevated charge-offs in the single family residential portfolio as compared to prior to the 2009-2011 financial crisis.
	The following tables shows a summary of loans collectively and individually evaluated for impairment and the related allocation of general and specific reserves as of March 31, 2014 and September 30, 2013:

	New Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-01, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. This ASU apply to all reporting entities that invest in qualified affordable housing projects through limited liability entities that are flow through entities for tax purposes. The amendments in this ASU eliminate the effective yield election and permit reporting entities to make an accounting policy election to account for their 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 statement as a component of income tax expense (benefit). Those not electing the proportional amortization method would account for the investment using the equity method or cost method. The amendments in this ASU should be applied retrospectively to all periods presented. The amendments in this ASU are effective for public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. The Company has adopted this ASU as of December 31, 2013. It has been adopted prospectively, as the retrospective adjustments were not material. The amount of affordable housing tax credits that are expected to be recognized during the 2014 calendar year is $3 million. The net investment balance recognized as of March 31, 2014 is $33 million. Using the proportional amortization method, the amount recognized as a component of income tax expense for the 2014 calendar year is $4 million. Contingent commitments for equity contributions during the 2014 calendar year are $31 million. Overall, this adoption does not have a material impact on the Company's 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. The amendments are intended to clarify 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 should be derecognized and the real estate recognized. These amendments clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either: (a) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure; or (b) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additional disclosures are required. The amendments are effective for public business entities for annual periods and interim periods within those annual periods beginning after December 15, 2014. This ASU is not expected to have a material impact on the Company's consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, A Similar Tax Loss, or a Tax Credit Carryforward Exists. Some entities present unrecognized tax benefits as a liability unless the unrecognized tax benefit is directly associated with a tax position taken in a tax year that results in, or that resulted in, the recognition of a net operating loss or tax credit carryforward for that year and the net operating loss or tax credit carryforward has not been utilized. Other entities present unrecognized tax benefits as a reduction of a deferred tax asset for a net operating loss or tax credit carryforward in certain circumstances. The objective of the amendments in this Update is to eliminate that diversity in practice. The guidance in this ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. This new guidance is not expected to have a material impact on the Company's consolidated financial statements.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Fair Value Measurements
	U.S. GAAP defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. U.S. GAAP also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:
	Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active exchange markets that the entity has the ability to access as of the measurement date.
	Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active and other inputs that are observable or can be corroborated by observable market data.
	Level 3: Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
	We have established and documented the Company's process for determining the fair values of the Company's assets and liabilities, where applicable. Fair value is based on quoted market prices, when available, for identical or similar assets or liabilities. In the absence of quoted market prices, fair value is determined using valuation models or third-party appraisals. The following is a description of the valuation methodologies used to measure and report the fair value of financial assets and liabilities on a recurring or nonrecurring basis:
	Measured on a Recurring Basis
	Securities
	Securities available for sale are recorded at fair value on a recurring basis. Most securities at fair value are priced using model pricing based on the securities' relationship to other benchmark quoted prices as provided by an independent third party, and under the provisions of the Fair Value Measurements and Disclosures topic of the FASB Accounting Standards Codification are considered a Level 2 input method. Securities that are traded on active exchanges are considered a Level 1 input method.
	The following tables present the balance of assets measured at fair value on a recurring basis at March 31, 2014 and September 30, 2013:

	Measured on a Nonrecurring Basis
	Impaired Loans & Real Estate Held for Sale
	From time to time, and on a nonrecurring basis, fair value adjustments to collateral-dependent loans and real estate held for sale are recorded to reflect write-downs of principal balances based on the current appraised or estimated value of the collateral. When management determines that the fair value of the collateral or the real estate held for sale requires additional adjustments, either as a result of a non-current appraisal value or when there is no observable market price, the Company classifies the impaired loan or real estate held for sale as Level 3. Level 3 assets recorded at fair value on a nonrecurring basis at March 31, 2014 included loans for which a specific reserve allowance was established or a partial charge-off was recorded based on the fair value of collateral, as well as covered REO and real estate held for sale for which fair value of the properties was less than the cost basis.
	Real estate held for sale consists principally of properties acquired through foreclosure.
	The following tables present the aggregated balance of assets measured at estimated fair value on a nonrecurring basis through the six months ended March 31, 2014 and March 31, 2013, and the total losses (gains) resulting from those fair value adjustments for the quarters and six months ended March 31, 2014 and March 31, 2013. These estimated fair values are shown gross of estimated selling costs.

	-1	The losses represents remeasurements of collateral-dependent loans.
	-2	The losses represents aggregate writedowns and charge-offs on real estate held for sale.
	There were no liabilities carried at fair value, measured on a recurring or nonrecurring basis, at March 31, 2014 or March 31, 2013.
	The following describes the process used to value Level 3 assets measured on a nonrecurring basis:
Impaired loans - The Company adjusts the carrying amount of impaired loans when there is evidence of probable loss and the expected fair value of the loan is less than its contractual amount. The amount of the impairment may be determined based on the estimated present value of future cash flows or the fair value of the underlying collateral. Impaired loans with a specific reserve allowance based on cash flow analysis or the value of the underlying collateral are classified as Level 3 assets.
The evaluations for impairment are prepared by the Problem Loan Review Committee, which is chaired by the Chief Credit Officer and includes the Loan Review manager and Special Credits manager, as well as senior credit officers, division managers and group executives, as applicable. These evaluations are performed in conjunction with the quarterly allowance for probable loan & lease losses process.
Applicable loans are evaluated for impairment on a quarterly basis. Loans included in the previous quarter's review are reevaluated and if their values are materially different from the prior quarter evaluation, the underlying information (loan balance and collateral value) are compared. Material differences are evaluated for reasonableness and discussions are held between the relationship manager and their division manager to understand the difference and determine if any adjustment is necessary. The inputs are developed and substantiated on a quarterly basis, based on current borrower developments, market conditions and collateral values. The following method is used to value impaired loans:
•	The fair value of the collateral, which may take the form of real estate or personal property, is based on internal estimates, field observations, assessments provided by third-party appraisers and other valuation models. The Company performs or reaffirms valuations of collateral-dependent impaired loans at least annually. Adjustments are made if management believes that more recent information is available and relevant with respect to the fair value of the collateral.
Real estate held for sale ("REO") - These assets are valued based on inputs such as appraisals and third-party price opinions, less estimated selling costs. Assets that are acquired through foreclosure are recorded initially at the lower of the loan balance or fair value at the date of foreclosure. After foreclosure, valuations are updated periodically, and current market conditions may require the assets to be written down further to a new cost basis. The following method is used to value real estate held for sale:
•	When a loan is reclassified from loan status to real estate held for sale due to the Company taking possession of the collateral, a Special Credits officer, along with the Special Credits manager, obtains a valuation, which may include a third-party appraisal, which is used to establish the fair value of the underlying collateral. The determined fair value net of selling costs, to the extent it does not exceed the carrying value of the loan, becomes the carrying value of the REO asset. In addition to the valuations from independent third-party sources, the carrying balance of REO assets are written down once a bona fide offer is contractually accepted, through execution of a Purchase and Sale Agreement, where the accepted price is lower than the current balance of the particular REO asset. The fair value of REO assets is re-evaluated quarterly and the REO asset is adjusted to reflect the lower of cost or fair value as necessary.
Fair Values of Financial Instruments
U. S. GAAP requires disclosure of fair value information about financial instruments, whether or not recognized on the statement of financial condition, for which it is practicable to estimate those values. Certain financial instruments and all non-financial instruments are excluded from the disclosure requirements. Accordingly, the aggregate fair value estimates presented do not reflect the underlying fair value of the Company. Although management is not aware of any factors that would materially affect the estimated fair value amounts presented below, such amounts have not been comprehensively revalued for purposes of these financial statements since the dates shown, and therefore, estimates of fair value subsequent to those dates may differ significantly from the amounts presented below.

The following methods and assumptions were used to estimate the fair value of financial instruments:
Cash and cash equivalents – The carrying amount of these items is a reasonable estimate of their fair value.
Available-for-sale securities and held-to-maturity securities – Securities at fair value are primarily priced using model pricing based on the securities' relationship to other benchmark quoted prices as provided by an independent third party, and under the provisions of the Fair Value Measurements and Disclosures topic of the FASB Accounting Standards Codification are considered a Level 2 input method. Equity securities which are exchange traded are considered a Level 1 input method.
Loans receivable and covered loans – For certain homogeneous categories of loans, such as fixed- and variable-rate residential mortgages, fair value is estimated for securities backed by similar loans, adjusted for differences in loan characteristics, using the same methodology described above for AFS and HTM securities. The fair value of other loan types is estimated by discounting the future cash flows and estimated prepayments using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining term. Some loan types were valued at carrying value because of their floating rate or expected maturity characteristics. Net deferred loan fees are not included in the fair value calculation but are included in the carrying amount.
FDIC indemnification asset – The fair value of the indemnification asset is estimated by discounting the expected future cash flows using the current rates.
FHLB stock – The fair value is based upon the par value of the stock which equates to its carrying value.
Customer accounts – The fair value of demand deposits, savings accounts, and money market accounts is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated by discounting the estimated future cash flows using the rates currently offered for deposits with similar remaining maturities.
FHLB advances and other borrowings – The fair value of FHLB advances and other borrowings is estimated by discounting the estimated future cash flows using rates currently available to the Company for debt with similar remaining maturities.

During the quarter ended March 31, 2014, there were no available-for-sale securities sold. There were $43,199,000 of available-for-sale securities sold during the quarter ended March 31, 2013, resulting in a gain of $0. These securities were acquired from South Valley Bank and sold on the same day. Substantially all mortgage-backed securities have contractual due dates that exceed 10 years.
The following tables indicate the total unrealized gross losses in the securities portfolio (shown above). The unrealized gross losses and fair value of securities as of March 31, 2014 and September 30, 2013 are also shown by the length of time that individual securities in each category have been in a continuous loss position. Management believes that the declines in fair value of these investments are not an other than temporary impairment.

	Covered Assets
	Covered assets represent loans and real estate held for sale acquired from the FDIC that are subject to loss sharing agreements and were $252,610,000 as of March 31, 2014, versus $326,927,000 as of September 30, 2013.
	Changes in the net carrying amount and accretable yield for acquired impaired and non-impaired covered loans for the year to date period ended March 31, 2014 and the fiscal year ended September 30, 2013 were as follows:

	(1) includes FDIC covered loans which were acquired as part of the South Valley Bank acquisition.
	(2) reclassification due to improvements/impairments in expected cash flows of the underlying pools.
	At March 31, 2014, none of the acquired impaired or non-impaired covered loans were classified as non-performing assets. Therefore, interest income, through accretion of the difference between the carrying amount of the loans and the expected cash flows, was recognized on all acquired loans. The allowance for credit losses related to the acquired loans results from decreased expectations of future cash flows due to increased credit losses for certain acquired loan pools.
	The outstanding principal balance of acquired covered loans was $285,769,000 and $362,248,000 as of March 31, 2014 and September 30, 2013, respectively. The discount balance related to the acquired covered loans was $54,095,000 and $66,301,000 as of March 31, 2014 and September 30, 2013, respectively.
	The following table shows the year to date activity for the FDIC indemnification asset:

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging Activities

The Company periodically enters into certain commercial loan interest rate swap agreements in order to provide commercial loan customers the ability to convert from variable to fixed interest rate payments, while the bank retains a variable rate loan. Under these agreements, the Company enters into a variable rate loan agreement and a swap agreement with the client. The swap agreement effectively converts the client’s variable rate loan into a fixed rate. The Company enters into a corresponding swap agreement with a third party in order to offset its exposure on the variable and fixed components of the client's swap agreement. The interest rate swap agreements with the clients and third parties are not designated as hedges under ASC 815, the Derivatives and Hedging topic; the instruments are marked to market in earnings.

The notional amount of open interest rate swap agreements at March 31, 2014 was $110,462,000 compared to $83,594,000 as of September 30, 2013. There was no impact to the statement of operations for the six-months ended March 31, 2014 as the asset and liability side of the swaps offset each other. The fee income related to swaps was $273,200 for the six months ended March 31, 2014.

The Company periodically enters into forward contracts to purchase mortgage-backed securities as part of its interest rate risk management program. The notional amount of commitments to purchase mortgage-backed securities at March 31, 2014 was $0 and at September 30, 2013 was $200,000,000. When there is a balance, the fair value of these contracts is included with the available-for-sale securities on the statement of financial condition.

The following table presents the fair value and balance sheet classification of derivatives not designated as hedging instruments at March 31, 2014 and September 30, 2013:

	Branch acquisition
	Upon the receipt of regulatory approvals and the completion of closing conditions, on May 2, 2014, the Bank completed its previously announced acquisition of 23 branches, located in Arizona and Nevada, from Bank of America, National Association.
	The 98,000 deposit accounts acquired totaled $539 million, which is $71 million less than the $610 million that was forecasted.  As a result of the decrease in deposits prior to closing, the purchase and sale contract adjusted the deposit premium from 1.30% of deposits to .50% of deposits.  The deposit premium paid amounted to $2.7 million. The acquisition also provided $5 million of loans, $11 million in branch properties and equipment, and $523 million in cash from the transaction.
