	The consolidated financial statements include the accounts of Hampden Bancorp, Inc. (the “Company”) and its wholly-owned subsidiaries, Hampden Bank (the “Bank”) and Hampden LS, Inc. Hampden Bank is a Massachusetts chartered stock savings bank. The Company contributed funds to Hampden LS, Inc. to enable it to make a 15-year loan to the employee stock ownership plan (the “ESOP”) to allow it to purchase shares of the Company’s common stock as part of the completion of the Company’s initial public offering. Hampden Bank has three wholly-owned subsidiaries, Hampden Investment Corporation and Hampden Investment Corporation II, which engage in buying, selling, holding and otherwise dealing in securities, and Hampden Insurance Agency, which ceased selling insurance products in November of 2000 and remains inactive. All significant intercompany accounts and transactions have been eliminated in consolidation.
	These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements and the instructions for Form 10-Q and Article 10 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, the information reflects all adjustments (consisting solely of normal recurring adjustments) that are necessary for a fair presentation. The results shown for the interim periods ended December 31, 2014 are not necessarily indicative of the results to be obtained for a full year. These consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended June 30, 2014 included in the Company’s most recent Annual Report on Form 10-K filed by the Company with the Securities and Exchange Commission (“SEC”) on September 12, 2014.
	In preparing the consolidated interim financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities, as of the date of the statement of financial condition and reported amounts of revenues and expenses for the periods presented. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and deferred income taxes.
	On November 3, 2014, the board of directors of the Company unanimously approved a merger agreement between the Company and Berkshire Hills Bancorp, Inc. ("Berkshire Hills"). The Company is holding a special meeting on Thursday, March 12, 2015 at 10:00 a.m., Eastern Time, at the Sheraton Springfield Monarch Place Hotel, Springfield, Massachusetts 01144, for its stockholders of record on January 29, 2015, to vote on the proposals necessary to complete the merger. If the merger agreement is approved and the merger is subsequently completed, the Company will merge with and into Berkshire Hills, the Company's separate corporate existence will thereupon cease and Berkshire Hills will continue as the surviving corporation. The expenses associated with this merger totaled $695,000 for the six months ended December 31, 2014.
	Under the terms of the merger agreement, each outstanding share of the Company's common stock will be converted into the right to receive 0.81 shares of Berkshire Hills' common stock. Berkshire Hills' common stock is listed on the New York Stock Exchange under the symbol ‘‘BHLB.’’ Completion of the merger is subject to the receipt of regulatory approvals and the approval of the stockholders of the Company, as well as customary conditions.

	In January 2014, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2014-04, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The ASU was issued to 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 (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) 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. Additionally, the ASU amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014, and the ASU is to be adopted using either a modified retrospective transition method or a prospective transition method. The Company does not believe this ASU will have a material effect on the Company's consolidated financial statements for the interim and annual periods other than the additional disclosures required.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share
	Basic earnings per share (“EPS”) excludes dilution and is calculated by dividing net income available to common stockholders by the weighted-average number of shares of common stock outstanding during the applicable period. Diluted EPS is computed in a manner similar to that of basic EPS except that the weighted-average number of common shares outstanding is increased to include the number of incremental common shares (computed using the treasury stock method) that would have been outstanding if all potentially dilutive common stock equivalents (such as stock options and unvested restricted stock) were issued during the period. Unallocated common shares held by the ESOP are shown as a reduction in stockholders' equity and are included in the weighted-average number of common shares outstanding for both basic and diluted EPS calculations as they are committed to be released.
	Earnings per common share have been computed based upon the following:

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	Fair Value of Assets and Liabilities
	GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. GAAP establishes a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following three levels:
	Level 1:		Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available.
	Level 2:		Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; and quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs to the valuation methodology are derived principally from or can be corroborated by observable market data by correlation or other means.
	Level 3:		Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Level 3 assets and liabilities include financial instruments whose value is determined using discounted cash flow methodologies, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
	Where assets or liabilities are measured at fair value, transfers between levels are recognized at the end of the reporting period, if applicable.
	Methods and assumptions for valuing the Company’s financial instruments are set forth below. Estimated fair values are calculated based on the value without regard to any premium or discount that may result from concentrations of ownership of a financial instrument, possible tax ramifications or estimated transaction costs.
	Cash and cash equivalents: The carrying amounts of cash and short-term investments approximate fair values.
	Securities: The securities measured at fair value utilizing Level 1 and Level 2 inputs are government-sponsored enterprises, corporate bonds and other obligations, mortgage-backed securities and common stocks. The fair values used by the Company are obtained from an independent pricing service which are not adjusted by management and, represents either quoted market prices for identical securities, quoted market prices for comparable securities or fair values determined by pricing models that consider observable market data, such as interest rate volatilities, credit spreads and prices from market makers and live trading systems and other market indicators, industry and economic events. Municipal securities are valued utilizing Level 3 inputs. Since there is no readily available market pricing and no active market to sell these securities, management believes that the amortized cost of these securities approximates fair value based on their relatively short terms to maturity.
	Federal Home Loan Bank of Boston ("FHLB") stock: The carrying amount of FHLB stock approximates fair value based upon the redemption provisions of the FHLB.
	Loans held for sale: Fair value of loans held for sale are estimated based on commitments on hand from investors or prevailing market prices.
	Loans: Fair values for loans are estimated using discounted cash flow analysis, using market interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. This analysis assumes no prepayment. Fair values for non-performing loans are estimated using discounted cash flow analysis or underlying collateral values, where applicable.
	Mortgage servicing rights: Mortgage servicing rights (“MSR”) are the rights of a mortgage servicer to collect mortgage payments and forward them, after deducting a fee, to the mortgage lender. The fair value of servicing rights is estimated using a present value cash flow model. The fair value of MSR is highly sensitive to changes in assumptions. Changes in prepayment speed assumptions generally have the most significant impact on the fair value of our MSR. Generally, as interest rates decline, mortgage loan prepayments accelerate due to increased refinance activity, which results in a decrease in the fair value of MSR. As interest rates rise, mortgage loan prepayments slow down, which results in an increase in the fair value of MSR. Thus, any measurement of the fair value of our MSR is limited by the conditions existing and the assumptions utilized as of a particular point in time, and those assumptions may not be appropriate if they are applied at a different point in time.
	Deposits and mortgage escrow accounts: The fair values for non-certificate accounts and mortgage escrow accounts are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for certificate accounts are estimated using a discounted cash flow calculation that applies market interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.
	Short-term borrowings: The carrying amount of short-term borrowings approximates fair value.
	Long-term debt: The fair values of the Company's advances are estimated using discounted cash flow analysis based on current market borrowing rates for similar types of borrowing arrangements.
	Accrued interest: The carrying amounts of accrued interest approximate fair value.
	Off-balance-sheet instruments: Fair values for off-balance-sheet lending commitments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties' credit standing. The estimated fair value of off-balance sheet financial instruments at December 31, 2014 and June 30, 2014 were not material.
	The Company does not measure any liabilities at fair value on either a recurring or non-recurring basis.

	Also, the Company may be required, from time to time, to measure certain other financial assets at fair value on a non-recurring basis in accordance with GAAP.  These adjustments to fair value usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets. The following table summarizes the carrying value of the related individual assets as of December 31, 2014 and June 30, 2014, all classified in Level 3 fair value hierarchy:
		December 31,			June 30,
		2014			2014
		(In Thousands)
	Impaired loans	$	455		$	461
	Other real estate owned ("OREO")	502			309
	Total	$	957		$	770
	During the six months ended December 31, 2014 and 2013 there were no transfers between Levels 1, 2, or 3.
	The amount of impaired loans represents the carrying value of loans that include adjustments which are based on the estimated fair value of the underlying collateral. The fair value of collateral used by the Company represents the current tax assessed value, discounted by 20%. This data includes information such as selling price of similar properties, expected future cash flows or earnings of the subject property based on current market expectations, as well as relevant legal, physical and economic factors. If the impaired loan is being actively marketed, the Company uses the realtor’s market analysis or listing price discounted by 10% and less 5% for realtor commission, instead of the tax assessment. The Company had a $592,000 and a $641,000 loss on impaired loans for the three and six months ended December 31, 2014, respectively. There was no gain or loss for the three and six months ended December 31, 2013. Any resulting losses are recognized in earnings through the provision for loan losses. The Company charges off any collateral shortfall on collateral dependent impaired loans.
	The Company classifies property acquired through foreclosure or acceptance of a deed in lieu of foreclosure as OREO in its consolidated financial statements. When property is placed into OREO, it is recorded at the fair value less estimated costs to sell at the date of foreclosure or acceptance of deed in lieu of foreclosure. At the time of transfer to OREO, any excess of carrying value over fair value is charged to the allowance for loan losses. Management, or its designee, inspects all OREO property periodically. Holding costs and declines in fair value result in charges to expense after the property is acquired. The Company had a $9,000 loss on OREO for the three months ended December 31, 2014 and a $36,000 gain on OREO for the six months ended December 31, 2014. The Company had a $15,000 and a $19,000 loss on OREO for the three and six months ended December 31, 2013, respectively.
	The fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company's various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Certain financial instruments and all non-financial instruments are exempt from disclosure requirements. Accordingly, the aggregate fair value amounts presented herein may not necessarily represent the underlying fair value of the Company.
	The carrying amounts and related estimated fair values of the Company's financial instruments are as follows. Certain financial instruments and all non-financial instruments are exempt from disclosure requirements. Accordingly, the aggregate fair value amounts presented herein may not necessarily represent the underlying fair value of the Company.

Management conducts, at least on a quarterly basis, a review of our investment securities to determine if the value of any security has declined below its cost or amortized cost and whether such decline represents other-than-temporary impairment (“OTTI”). There was no impairment charge recognized for the six months ended December 31, 2014 and 2013.
At December 31, 2014, 52 debt securities had unrealized losses with an aggregate depreciation of 2.0% from the Company's amortized cost basis. In analyzing an issuer's financial condition, management considers whether the securities are issued by the federal government, its agencies or government-sponsored enterprises, whether downgrades by bond rating agencies have occurred, and industry analysts' reports. The unrealized losses in residential mortgage-backed securities were primarily caused by interest rate changes. As management has not decided to sell these securities, nor is it likely that the Company will be required to sell these securities, no declines are deemed to be other than temporary. At December 31, 2014, ten securities issued by private mortgage originators had unrealized losses. Such securities had an amortized cost of $826,000 and a fair value of $818,000. All of these investments are “Senior” Class tranches and have underlying credit enhancement. These securities were originated in the period 2002-2005 and are performing in accordance with contractual terms. Management estimates the loss projections for each security by evaluating the industry rating, amount of delinquencies, amount of foreclosure, amount of other real estate owned, average credit scores, average amortized loan to value and credit enhancement. Based on this review, management determined that no OTTI existed as of December 31, 2014.

	Total loans, net	$	509,845					$	507,635
	Management performs a quarterly evaluation of the adequacy of the allowance for loan losses. The analysis of the allowance for loan losses has two components: specific and general allocations, which are further described below.
	Specific Allocation
	Specific allocations are made for loans determined to be impaired. Impairment is measured by determining the present value of expected future cash flows or fair value of collateral for collateral dependent loans. The Company charges off any collateral shortfall on collaterally dependent impaired loans.
	A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Impaired loans are generally placed on non-accrual status either when there is reasonable doubt as to the full collection of payments or when the loans become 90 days past due, unless an evaluation clearly indicates that the loan is well secured and in the process of collection. Impairment is measured on a loan by loan basis for commercial loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral, adjusted for market conditions and selling expenses, if the loan is collateral dependent.
	The Company may periodically agree to modify the contractual terms of loans. When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a troubled debt restructure (“TDR”). All TDRs are initially classified as impaired and may be evaluated for removal from impaired status after one year of current payments for a modified loan with a market rate for that borrower at the time of restructuring.
	General Allocation
	The general allocation is determined by segregating the remaining loans by type of loan and payment history. Consideration is given to historical loss experience and qualitative factors such as delinquency trends, changes in underwriting standards or lending policies, procedures and practices, experience and depth of management and lending staff, and general economic conditions. This analysis establishes loss factors that are applied to the loan groups to determine the amount of the general allocations. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revisions based upon changes in economic and real estate market conditions. Actual loan losses may be significantly more than the allowance for loan losses that have been established which could have a material negative effect on financial results. There were no changes in the Company’s policies or methodology pertaining to the general component of the allowance for loan losses during the six months ended December 31, 2014.
	On a quarterly basis, management’s Loan Review Committee ("the Committee") reviews the current status of various loan assets in order to evaluate the adequacy of the allowance for loan losses. In this evaluation process specific loans with risk ratings of six (special mention) or higher are analyzed to determine their potential risk of loss. This process concentrates on watch list, non-accrual and classified loans. Any loan determined to be impaired is evaluated for potential loss exposure. Any shortfall results in a charge-off if the likelihood of loss is evaluated as probable. The Company’s policy for charging off uncollectible loans is based on an analysis of the financial condition of the borrower and/or the collateral value. To determine the adequacy of collateral on a particular loan, an estimate of the fair market value of the collateral is based on the most current appraised value, discounted cash flow valuation or other available information.
	The qualitative factors are assessed based on the various risk characteristics of each loan segment. Risk characteristics relevant to each portfolio segment are as follows:
	Residential real estate - The Company generally does not originate loans with a loan-to-value ratio greater than 80% unless there is private mortgage insurance. All loans in this segment are collateralized by one- to four-family residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment.
	Commercial real estate - Loans in these segments are primarily income-producing properties throughout Massachusetts and Connecticut. The underlying cash flows generated by the properties can be adversely impacted by a downturn in the economy, as evidenced by increased vacancy rates, which in turn will have an effect on the credit quality in this segment. Management requires annual borrower financial statements, obtains rent rolls annually and continually monitors the cash flows of these loans.
	Home equity loans - Loans in this segment are secured by first or second mortgages on one- to four-family owner occupied properties, and are generally underwritten in amounts such that the combined first and second mortgage balances generally do not exceed 85% of the value of the property serving as collateral at time of origination. The lines-of-credit are available to be drawn upon for 10 to 20 years, at the end of which time they become term loans amortized over 5 to 10 years. Interest rates on home equity lines normally adjust based on the month-end prime rate published in the Wall Street Journal.
	Residential construction loans - Loans in this segment primarily include construction to permanent non-speculative real estate loans. All loans in this segment are collateralized by one- to four-family residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment.
	Commercial construction loans - Loans in this segment primarily include construction to permanent non-speculative real estate loans. The underlying cash flows generated by the properties may be adversely impacted by a downturn in the economy, which in turn will have an effect on the credit quality in this segment.
	Commercial loans - Loans in this segment are made to businesses and are generally secured by assets of the business. Repayment is expected from the cash flows of the business. A weakened economy may have an effect on the credit quality in this segment.
	Automobile and other secured loans - Loans in this segment include consumer non-real estate secured loans that the Company originates as well as automobile loans that the Company purchases from a third party. The Company has the ability to select the automobile loans it purchases based on its own underwriting standards.
	Manufactured home loans - Loans in this segment are secured by first liens on properties located primarily in the Northeast. Repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates, will have an effect on the credit quality in this segment. The Company has the ability to select the manufactured home loans it purchases based on its own underwriting standards.
	Other consumer loans - Loans in this segment are generally unsecured and repayment is dependent on the credit quality of the individual borrower.
	Credit Quality Information
	The Company utilizes a nine grade internal loan rating system for all loans as follows:
	Loans rated 1 – 5: Loans in these categories are considered “pass” rated loans with low to average risk.
	Loans rated 6: Loans in this category are considered “special mention.” These loans are starting to show signs of potential weakness and are being closely monitored by management.
	Loans rated 7: Loans in this category are considered “substandard.” Generally, a loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected.
	Loans rated 8: Loans in this category are considered “doubtful.” Loans classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable.
	Loans rated 9: Loans in this category are considered uncollectible (“loss”) and of such little value that their continuance as loans is not warranted. These loans are generally charged off at each quarter end.
	On an annual basis, or more often if needed, the Company formally reviews the ratings on all commercial real estate, commercial construction and commercial loans. The Company engages an independent third-party to review a significant portion of loans within these segments. Management uses the results of these reviews as part of its annual review process. All credits rated 6 or worse are reviewed on a quarterly basis by management. At origination, management assigns risk ratings to one- to four-family residential loans, home equity loans, residential construction loans, manufactured home loans, and other consumer loans. The Company updates these risk ratings as needed based primarily on delinquency, bankruptcy, or tax delinquency.

The Company has transferred a portion of its originated commercial real estate and commercial loans to participating lenders. The amounts transferred have been accounted for as sales and are therefore not included in the Company’s accompanying consolidated balance sheets. The Company and participating lenders share in any gains or losses that may result from a borrower’s lack of compliance with contractual terms of the loan. The Company continues to service the loans on behalf of the participating lenders and, as such, collects cash payments from the borrowers, remits payments (net of servicing fees) to participating lenders and disburses required escrow funds to relevant parties. At December 31, 2014 and June 30, 2014, the Company was servicing loans for participants aggregating $41.3 million and $34.4 million, respectively.

Basis_of_Presentation_and_Cons1

Basis of Presentation and Consolidation (Policies)	6 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	The consolidated financial statements include the accounts of Hampden Bancorp, Inc. (the “Company”) and its wholly-owned subsidiaries, Hampden Bank (the “Bank”) and Hampden LS, Inc. Hampden Bank is a Massachusetts chartered stock savings bank. The Company contributed funds to Hampden LS, Inc. to enable it to make a 15-year loan to the employee stock ownership plan (the “ESOP”) to allow it to purchase shares of the Company’s common stock as part of the completion of the Company’s initial public offering. Hampden Bank has three wholly-owned subsidiaries, Hampden Investment Corporation and Hampden Investment Corporation II, which engage in buying, selling, holding and otherwise dealing in securities, and Hampden Insurance Agency, which ceased selling insurance products in November of 2000 and remains inactive. All significant intercompany accounts and transactions have been eliminated in consolidation.
	These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements and the instructions for Form 10-Q and Article 10 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, the information reflects all adjustments (consisting solely of normal recurring adjustments) that are necessary for a fair presentation. The results shown for the interim periods ended December 31, 2014 are not necessarily indicative of the results to be obtained for a full year. These consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended June 30, 2014 included in the Company’s most recent Annual Report on Form 10-K filed by the Company with the Securities and Exchange Commission (“SEC”) on September 12, 2014.
	In preparing the consolidated interim financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities, as of the date of the statement of financial condition and reported amounts of revenues and expenses for the periods presented. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and deferred income taxes.
	On November 3, 2014, the board of directors of the Company unanimously approved a merger agreement between the Company and Berkshire Hills Bancorp, Inc. ("Berkshire Hills"). The Company is holding a special meeting on Thursday, March 12, 2015 at 10:00 a.m., Eastern Time, at the Sheraton Springfield Monarch Place Hotel, Springfield, Massachusetts 01144, for its stockholders of record on January 29, 2015, to vote on the proposals necessary to complete the merger. If the merger agreement is approved and the merger is subsequently completed, the Company will merge with and into Berkshire Hills, the Company's separate corporate existence will thereupon cease and Berkshire Hills will continue as the surviving corporation. The expenses associated with this merger totaled $695,000 for the six months ended December 31, 2014.
	Under the terms of the merger agreement, each outstanding share of the Company's common stock will be converted into the right to receive 0.81 shares of Berkshire Hills' common stock. Berkshire Hills' common stock is listed on the New York Stock Exchange under the symbol ‘‘BHLB.’’ Completion of the merger is subject to the receipt of regulatory approvals and the approval of the stockholders of the Company, as well as customary conditions.
Recent Accounting Policies	Recent Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2014-04, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The ASU was issued to 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 (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) 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. Additionally, the ASU amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014, and the ASU is to be adopted using either a modified retrospective transition method or a prospective transition method. The Company does not believe this ASU will have a material effect on the Company's consolidated financial statements for the interim and annual periods other than the additional disclosures required.
Fair Value Hierarchy	GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. GAAP establishes a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following three levels:
	Level 1:	Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available.
	Level 2:	Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; and quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs to the valuation methodology are derived principally from or can be corroborated by observable market data by correlation or other means.
	Level 3:	Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Level 3 assets and liabilities include financial instruments whose value is determined using discounted cash flow methodologies, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
