Basis of Presentation [Abstract]	'
Basis of Presentation	'
	Note 1 — Basis of Presentation
	The unaudited interim consolidated financial statements include the accounts of Waterstone Financial, Inc. (the "Company") and the Company's subsidiaries.
	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles ("GAAP") for interim financial information, Rule 10-01 of Regulation S-X and the instructions to Form 10-Q. The financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring accruals) necessary to present fairly the financial position, results of operations, changes in shareholders' equity, and cash flows of the Company for the periods presented.
	The accompanying unaudited consolidated financial statements and related notes should be read in conjunction with the Company's December 31, 2012 Annual Report on Form 10-K. Operating results for the nine and three months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013 or for any other period.
	The preparation of the unaudited consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates and assumptions include the allowance for loan losses, deferred income taxes and real estate owned. Actual results could differ from those estimates.
	Recent Accounting Pronouncements
	In July 2013, the FASB issued ASU No. 2013-10, "Derivatives and Hedging (Topic 815): Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes (a consensus of the FASB Emerging Issues Task Force)." This ASU permits the Fed Funds Effective Swap Rate to be used as a U.S. benchmark interest rate for hedge accounting purposes, in addition to US Treasuries (UST) and London Interbank Offered Rate (LIBOR). The amendment also removes the restriction on using different benchmark rates for similar hedges. The amendment applies to all entities that elect to apply hedge accounting of the benchmark interest rate. This ASU is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The adoption of this standard is not expected to have a material impact on the Company's consolidated financial position or results of operations.
	In July 2013, the FASB issued ASU No. 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exits." This ASU provides that an unrecognized tax benefit, or a portion thereof, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use the deferred tax asset for such purpose. In these cases, the unrecognized tax benefit should be presented as a liability. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption and retrospective application is permitted. The Company is in the process of evaluating the impact of this standard to its existing disclosures and currently does not expect this standard to have a material impact on the Company's consolidated financial position or results of operations.

	The Company's mortgage-backed securities and collateralized mortgage obligations issued by government sponsored enterprises are guaranteed by Fannie Mae, Freddie Mac or Ginnie Mae. At September 30, 2013, $987,000 of the Company's government sponsored enterprise bonds and $99.7 million of the Company's mortgage related securities were pledged as collateral to secure repurchase agreement obligations of the Company.
	The amortized cost and fair values of investment securities by contractual maturity at September 30, 2013 are shown below. Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

	The Company reviews the investment securities portfolio on a quarterly basis to monitor its exposure to other-than-temporary impairment. In evaluating whether a security's decline in market value is other-than-temporary, management considers the length of time and extent to which the fair value has been less than cost, financial condition of the issuer and the underlying obligors, quality of credit enhancements, volatility of the fair value of the security, the expected recovery period of the security and ratings agency evaluations. In addition the Company may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the value of any underlying collateral. For certain securities in unrealized loss positions, the Company prepares cash flow analyses to compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security.
As of September 30, 2013, the Company identified two municipal securities that were deemed to be other-than-temporarily impaired. Both securities were issued by a tax incremental district in a municipality located in Wisconsin. During the year ended December 31, 2012, the Company received audited financial statements with respect to the municipal issuer that called into question the ability of the underlying taxing district that issued the securities to operate as a going concern. During the year ended December 31, 2012, the Company's analysis of these securities resulted in $100,000 in credit losses that were charged to earnings with respect to these two municipal securities. No additional credit loss was recognized during the nine months ended September 30, 2013. As of September 30, 2013, these securities had a combined amortized cost of $215,000 and a combined estimated fair value of $189,000. As of September 30, 2013, the Company had one municipal security which had been in an unrealized loss position for twelve months or longer. This security was determined not to be other-than-temporarily impaired as of September 30, 2013. During the year ended December 31, 2012, two private-label collateralized mortgage obligations, that had been identified as other than temporarily impaired, were sold at a combined gain of $282. At the time of sale, these securities had a combined amortized cost of $18.0 million.
The following table presents the change in other-than-temporary credit related impairment charges on securities available for sale for which a portion of the other-than-temporary impairments related to other factors was recognized in other comprehensive loss.

Credit-related impairments on securities as of September 30, 2013	$	100
Exclusive of the aforementioned securities, the Company has determined that the decline in fair value of the remaining securities is not attributable to credit deterioration. Based on the foregoing evaluation criteria, and as the Company does not intend to sell nor is it more likely than not that it will be required to sell these securities before recovery of the amortized cost basis, these securities are not considered other-than-temporarily impaired.
Continued deterioration of general economic market conditions could result in the recognition of future other-than-temporary impairment losses within the investment portfolio and such amounts could be material to our consolidated financial statements.
During the nine months ended, September 30, 2013, proceeds from the sale of securities totaled $921,000 and resulted in losses totaling $9,000. The $9,000 loss included in (loss) gain on sale of available for sale securities in the consolidated statements of income during the nine months ended, September 30, 2013 was reclassified from accumulated other comprehensive income. During the nine months ended, September 30, 2012, proceeds from the sale of securities totaled $11.9 million and resulted in gains totaling $241,000. The $241,000 gain included in (loss) gain on sale of available for sale securities in the consolidated statements of income during the nine months ended, September 30, 2012 was reclassified from accumulated other comprehensive income.

	Loans receivable at September 30, 2013 and December 31, 2012 are summarized as follows:
			30-Sep-13			31-Dec-12
			(In Thousands)
	Mortgage loans:
	Residential real estate:
	One- to four-family		$	419,084			460,821

	The Company provides several types of loans to its customers, including residential, construction, commercial and consumer loans. Significant loan concentrations are considered to exist for a financial institution when there are amounts loaned to one borrower or to multiple borrowers engaged in similar activities that would cause them to be similarly impacted by economic or other conditions. While credit risks are geographically concentrated in the Company's Milwaukee metropolitan area, and while 88.9% of the Company's loan portfolio involves loans that are secured by residential real estate, there are no concentrations with individual or groups of related borrowers. While the real estate collateralizing these loans is residential in nature, it ranges from owner-occupied single family homes to large apartment complexes. In addition, real estate collateralizing $61.7 million, or 5.7% of total loans, is located outside of the state of Wisconsin.
	Qualifying loans receivable totaling $887.5 million and $801.6 million at September 30, 2013 and December 31, 2012, respectively, are pledged as collateral against $350.0 million in outstanding Federal Home Loan Bank of Chicago advances under a blanket security agreement.
	An analysis of past due loans receivable as of September 30, 2013 and December 31, 2012 follows:

Factors that are important to managing overall credit quality include sound loan underwriting and administration, systematic monitoring of existing loans and commitments, effective loan review on an ongoing basis, early identification of potential problems, an allowance for loan losses, and sound non-accrual and charge-off policies. Our underwriting policies require an officers' loan committee to review and approve all loans in excess of $500,000. In addition, an independent loan review function exists for all loans. Our ability to manage credit risk depends in large part on our ability to properly identify and manage problem loans. To do so, we maintain a loan review system under which our credit management personnel review non-owner occupied one- to four-family, over four-family, construction and land, commercial real estate and commercial loans that individually, or as part of an overall borrower relationship, exceed $1.0 million in potential exposure. Loans meeting these criteria are reviewed on an annual basis, or more frequently if the loan renewal is less than one year. With respect to this review process, management has determined that pass loans include loans that exhibit acceptable financial statements, cash flow and leverage. Watch loans have potential weaknesses that deserve management's attention and, if left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the credit. Substandard loans are considered inadequately protected by the current net worth and paying capacity of the obligor or the collateral pledged. These loans generally have a well-defined weakness that may jeopardize liquidation of the debt and are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Finally, a loan is considered to be impaired when it is probable that the Bank will not be able to collect all amounts due according to the contractual terms of the loan agreement. Management has determined that all non-accrual loans and loans modified under troubled debt restructurings meet the definition of an impaired loan.
The Company's procedures dictate that an updated valuation must be obtained with respect to underlying collateral at the time a loan is deemed impaired. Updated valuations may also be obtained upon transfer from loans receivable to real estate owned based upon the age of the prior appraisal, changes in market conditions or known changes to the physical condition of the property.
Estimated fair values are reduced to account for sales commissions, broker fees, unpaid property taxes and additional selling expenses to arrive at an estimated net realizable value. The adjustment factor is based upon the Company's actual experience with respect to sales of real estate owned over the prior two years. An additional adjustment factor is applied by appraisal vintage to account for downward market pressure since the date of appraisal. The additional adjustment factor is based upon relevant sales data available for our general operating market as well as company-specific historical net realizable values as compared to the most recent appraisal prior to disposition.
With respect to over-four family income-producing real estate, appraisals are reviewed and estimated collateral values are adjusted by updating significant appraisal assumptions to reflect current real estate market conditions. Significant assumptions reviewed and updated include the capitalization rate, rental income and operating expenses. These adjusted assumptions are based upon recent appraisals received on similar properties as well as on actual experience related to real estate owned and currently under Company management.
The following tables present data on impaired loans at September 30, 2013 and December 31, 2012.

The difference between a loan's recorded investment and the unpaid principal balance represents a partial charge-off resulting from a confirmed loss due to the value of the collateral securing the loan being below the loan balance and management's assessment that the full collection of the loan balance is not likely.
When a loan is considered impaired, interest payments received are treated as interest income on a cash basis as long as the remaining book value of the loan (i.e., after charge-off of all identified losses) is deemed to be fully collectible. If the remaining book value is not deemed to be fully collectible, all payments received are applied to unpaid principal. Determination as to the ultimate collectability of the remaining book value is supported by an updated credit department evaluation of the borrower's financial condition and prospects for repayment, including consideration of the borrower's sustained historical repayment performance and other relevant factors.
The determination as to whether an allowance is required with respect to impaired loans is based upon an analysis of the value of the underlying collateral and/or the borrower's intent and ability to make all principal and interest payments in accordance with contractual terms. The evaluation process is subject to the use of significant estimates and actual results could differ from estimates. This analysis is primarily based upon third party appraisals and/or a discounted cash flow analysis. In those cases in which no allowance has been provided for an impaired loan, the Company has determined that the estimated value of the underlying collateral exceeds the remaining outstanding balance of the loan. Of the total $43.6 million of impaired loans as of September 30, 2013 for which no allowance has been provided, $10.6 million in charge-offs have been recorded to reduce the unpaid principal balance to an amount that is commensurate with the loan's net realizable value, using the estimated fair value of the underlying collateral. To the extent that further deterioration in property values continues, the Company may have to reevaluate the sufficiency of the collateral servicing these impaired loans resulting in additional provisions to the allowance for loans losses or charge-offs.
At September 30, 2013, total impaired loans includes $47.7 million of troubled debt restructurings. Troubled debt restructurings involve granting concessions to a borrower experiencing financial difficulty by modifying the terms of the loan in an effort to avoid foreclosure. The vast majority of debt restructurings include a modification of terms to allow for an interest only payment and/or reduction in interest rate. The restructured terms are typically in place for six to twelve months. At December 31, 2012, total impaired loans included $59.6 million of troubled debt restructurings.

At September 30, 2013, $47.7 million in loans had been modified in troubled debt restructurings and $22.3 million of these loans were included in the non-accrual loan total. The remaining $25.4 million, while meeting the internal requirements for modification in a troubled debt restructuring, were current with respect to payments under their original loan terms at the time of the restructuring and thus, continued to be included with accruing loans. Provided these loans perform in accordance with the modified terms, they will continue to be accounted for on an accrual basis.
All loans that have been modified in a troubled debt restructuring are considered to be impaired. As such, an analysis has been performed with respect to all of these loans to determine the need for a valuation reserve. When a loan is expected to perform in accordance with the restructured terms and ultimately return to and perform under contract terms, a valuation allowance is established for an amount equal to the excess of the present value of the expected future cash flows under the original contract terms as compared with the modified terms, including an estimated default rate. When there is doubt as to the borrower's ability to perform under the restructured terms or ultimately return to and perform under market terms, a valuation allowance is established equal to the impairment when the carrying amount exceeds fair value of the underlying collateral. As a result of the impairment analysis, a $2.9 million valuation allowance has been established as of September 30, 2013 with respect to the $47.7 million in troubled debt restructurings. As of December 31, 2012, a $6.4 million valuation allowance had been established with respect to the $59.6 million in troubled debt restructurings.
After a troubled debt restructuring reverts to market terms, a minimum of six consecutive contractual payments must be received prior to consideration for a return to accrual status. If an updated credit department review indicates no other evidence of elevated credit risk, the loan is returned to accrual status at that time.

	The short-term repurchase agreements represent the outstanding portion of a total $90.0 million commitment with two unrelated banks. The short-term repurchase agreements are utilized by Waterstone Mortgage Corporation to finance loans originated for sale. These agreements are secured by the underlying loans being financed. Related interest rates are based upon the note rate associated with the loans being financed. The first of the two short-term repurchase agreements has an outstanding balance of $28.8 million, a rate of 3.18 % and a total commitment of $40.0 million at September 30, 2013. The second short-term repurchase agreement has an outstanding balance of $8.4 million, a rate of 3.30 % and a total commitment of $50.0 million at September 30, 2013.
	The $220.0 million in advances due in 2016 consist of eight advances with fixed rates ranging from 4.01% to 4.82% callable quarterly until maturity.
	The $65.0 million in advances due in 2017 consist of three advances with fixed rates ranging from 3.09% to 3.46% callable quarterly until maturity.
	The $65.0 million in advances due in 2018 consist of three advances with fixed rates ranging from 2.73% to 3.11% callable quarterly until maturity.
	The $84.0 million in repurchase agreements have fixed rates ranging from 2.89% to 4.31% callable quarterly until their maturity in 2017. The repurchase agreements are collateralized by securities available for sale with an estimated fair value of $99.7 million at September 30, 2013 and $101.9 million at December 31, 2012.
	The Company selects loans that meet underwriting criteria established by the Federal Home Loan Bank Chicago (FHLBC) as collateral for outstanding advances. The Company's borrowings at the FHLBC are limited to 75% of the carrying value of unencumbered one- to four-family mortgage loans, 40% of the carrying value of home equity loans and 60% of the carrying value of over four-family loans. In addition, these advances are collateralized by FHLBC stock of $20.2 million at both September 30, 2013 and December 31, 2012. In the event of prepayment, the Company is obligated to pay all remaining contractual interest on the advance.

Regulatory Capital [Abstract]	'
Regulatory Capital	'
	Note 8 – Regulatory Capital
	The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements, or overall financial performance deemed by the regulators to be inadequate, can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank's assets, liabilities, and certain off-balance-sheet items, as calculated under regulatory accounting practices. The Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.
	Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of total and Tier I capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier I capital (as defined) to average assets (as defined). As of September 30, 2013, the Bank meets all capital adequacy requirements to which it is subject.
	Effective December 11, 2012, the WDFI and the Federal Deposit Insurance Corporation terminated a consent order originally agreed to by WaterStone Bank on November 25, 2009 and replaced it with a memorandum of understanding.  The memorandum of understanding requires, among other things, maintenance of a minimum Tier I capital ratio of 8.0 % and a minimum Total risk based cpaital ratio of 12.0 %.
	As of September 30, 2013 the most recent notification from the Federal Deposit Insurance Corporation categorized the Bank as quantitatively "well capitalized" under the regulatory framework for prompt corrective action. To be categorized as "well capitalized," the Bank must maintain minimum total risk-based, Tier I risk-based and Tier I leverage ratios, as set forth in the table below. There are no conditions or events since that notification that management believes have changed the Bank's category.
	As a state-chartered savings bank, the Bank is required to meet minimum capital levels established by the state of Wisconsin in addition to federal requirements. For the state of Wisconsin, regulatory capital consists of retained income, paid-in-capital, capital stock equity and other forms of capital considered to be qualifying capital by the Federal Deposit Insurance Corporation.
	The actual and required capital amounts and ratios for the Bank as of September 30, 2013 and December 31, 2012 are presented in the table below:

	Note 9 – Income Taxes
	Income tax expense increased from $216,000 during the nine months ended September 30, 2012 to $7.9 million for the nine months ended September 30, 2013. This increase was partially due to the increase in our income before income taxes, which increased from $17.1 million during the nine months ended September 30, 2012 to $20.7 million during the nine months ended September 30, 2013. During the third quarter of 2008, we established a valuation allowance against our net deferred tax assets. That valuation allowance effectively resulted in no income tax expense being recognized during the nine months ended September 30, 2012 other than state income taxes for states in which separate company returns are filed. During the fourth quarter of 2012, we released the valuation allowance against our net deferred tax assets. Income tax expense is recognized on the statement of income during the nine months ended September 30, 2013 at an effective rate of 38.4 % of pretax book income.
	As of September 30, 2013, net deferred tax assets totaled $14.3 million, which, in the judgment of management, will more-likely-than-not be fully realized. The largest components of the deferred tax asset are associated with the allowance for loan losses and basis adjustments on real estate owned. We are largely relying on earnings generated in the current year and forecasted earnings in future years in making the determination that we will more-likely-than-not realize our deferred tax asset.

liabilities subject to an enforceable master netting agreement [Text Block]	'
	Note 10 – Offsetting of Assets and Liabilities
	The Company enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities. In addition, the Company enters into agreements under which it sells loans held for sale subject to an obligation to repurchase the same loans. Under these arrangements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Company to repurchase the assets. As a result, these repurchase agreements are accounted for as collateralized financing arrangements (i.e., secured borrowings) and not as a sale and subsequent repurchase of assets. The obligation to repurchase the assets is reflected as a liability in the Company's consolidated statements of condition, while the securities and loans held for sale underlying the repurchase agreements remain in the respective investment securities and loans held for sale asset accounts. In other words, there is no offsetting or netting of the investment securities or loans held for sale assets with the repurchase agreement liabilities. One of the Company's two short-term repurchase agreements and all of the Company's long-term repurchase agreements are subject to master netting agreements, which sets forth the rights and obligations for repurchase and offset. Under the master netting agreement, the Company is entitled to set off the collateral placed with a single counterparty against obligations owed to that counterparty.
	The following table presents the liabilities subject to an enforceable master netting agreement as of September 30, 2013 and December 31, 2012.

Financial Instruments with Off Balance Sheet Risk [Abstract]	'
Financial Instruments with Off-Balance Sheet Risk	'
	The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.

	Standby letters of credit		882		736
	____________
	(1) Excludes commitments to originate loans held for sale, which are discussed in the following footnote.
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements of the Company. The Company evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management's credit evaluation of the counterparty. Collateral obtained generally consists of mortgages on the underlying real estate.
	Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company holds mortgages on the underlying real estate as collateral supporting those commitments for which collateral is deemed necessary.
	The Company has determined that there are no probable losses related to commitments to extend credit or the standby letters of credit as of September 30, 2013 and December 31, 2012.
	Residential mortgage loans sold to others are predominantly conventional residential first lien mortgages. The Company's agreements to sell residential mortgage loans in the normal course of business usually require certain representations and warranties on the underlying loans sold related to credit information, loan documentation and collateral, which if subsequently are untrue or breached, could require the Company to repurchase certain loans affected. The Company has only been required to make insignificant repurchases as a result of its representations and warranties. The Company's agreements to sell residential mortgage loans also contain limited recourse provisions. The recourse provisions are limited in that the recourse provision ends after certain payment criteria have been met. With respect to these loans, repurchase could be required if defined delinquency issues arose during the limited recourse period. Given that the underlying loans delivered to buyers are predominantly conventional first lien mortgages and that historical experience shows negligible losses and insignificant repurchase activity, management believes that losses and repurchases under the limited recourse provisions will continue to be insignificant.

Derivative Financial Instruments [Abstract]	'
Derivative Financial Instruments	'
	Note 12 – Derivative Financial Instruments
	In connection with its mortgage banking activities, the Company enters into derivative financial instruments as part of its strategy to manage its exposure to changes in interest rates. Mortgage banking derivatives include interest rate lock commitments provided to customers to fund mortgage loans to be sold in the secondary market and forward commitments for the future delivery of such loans to third party investors. It is the Company's practice to enter into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into in order to economically hedge the effect of future changes in interest rates on its commitments to fund the loans as well as on its portfolio of mortgage loans held for sale. The Company's mortgage banking derivatives have not been designated as being in hedge relationships. These instruments are used to manage the Company's exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements of ASC 815. Changes in the fair value of derivatives not designated in hedging relationships are recorded as a component of mortgage banking income in the Company's consolidated statements of operations. The Company does not use derivatives for speculative purposes.
	Forward commitments to sell mortgage loans represent commitments obtained by the Company from a secondary market agency to purchase mortgages from the Company at specified interest rates and within specified periods of time. Commitments to sell loans are made to mitigate interest rate risk on interest rate lock commitments to originate loans and loans held for sale. At September 30, 2013, the Company had forward commitments to sell mortgage loans with an aggregate notional amount of approximately $167.0 million and interest rate lock commitments with an aggregate notional amount of approximately $135.4 million.  The fair value of the forward commitments to sell mortgage loans at September 30, 2013 included a loss of $1.5 million that is reported as a component of other liabilities on the Company's consolidated statement of financial condition. The fair value of the interest rate locks at September 30, 2013 included a gain of $2.7 million that is reported as a component of other assets on the Company's consolidated statements of financial condition.
	In determining the fair value of its derivative loan commitments, the Company considers the value that would be generated by the loan arising from exercise of the loan commitment when sold in the secondary mortgage market. That value includes the price that the loan is expected to be sold for in the secondary mortgage market. The fair value of these commitments is recorded on the consolidated statements of financial condition with the changes in fair value recorded as a component of mortgage banking income.

Earnings (loss) per share	'
	Note 13 – Earnings per share
	Earnings per share are computed using the two-class method. Basic earnings per share is computed by dividing net income allocated to common shares by the weighted average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Participating securities include unvested restricted shares. Unvested restricted shares are considered participating securities because holders of these securities have the right to receive dividends at the same rate as holders of the Company's common stock. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding adjusted for the dilutive effect of all potential common shares. Unvested restricted stock and stock options are considered outstanding for diluted earnings per share only. Unvested restricted stock totaling 81,000 and 105,000 shares are considered outstanding for dilutive earnings per share for the nine months ended September 30, 2013 and September 30, 2012, respectively. Unvested stock options totaled 220,000 and 284,000 shares for the nine months ended September 30, 2013 and September 30, 2012, respectively.

Fair Value Measurements [Abstract]	'
Fair Value Measurements	'
	Note 14 – Fair Value Measurements
	The FASB issued an accounting standard (subsequently codified into ASC Topic 820, "Fair Value Measurements and Disclosures") which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. This accounting standard applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements. The standard also emphasizes that fair value (i.e., the price that would be received in an orderly transaction that is not a forced liquidation or distressed sale at the measurement date), among other things, is based on exit price versus entry price, should include assumptions about risk such as nonperformance risk in liability fair values, and is a market-based measurement, not an entity-specific measurement. When considering the assumptions that market participants would use in pricing the asset or liability, this accounting standard establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity's own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).
	The fair value hierarchy prioritizes inputs used to measure fair value into three broad levels.
	Level 1 inputs - In general, fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities that we have the ability to access.
	Level 2 inputs - Fair values determined by Level 2 inputs use inputs other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets where there are few transactions and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals.
	Level 3 inputs - Level 3 inputs are unobservable inputs for the asset or liability and include situations where there is little, if any, market activity for the asset or liability.
	In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
	The following table presents information about our assets recorded in our consolidated statement of financial position at their fair value on a recurring basis as of September 30, 2013 and December 31, 2012, and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value.

	The following summarizes the valuation techniques for assets recorded in our consolidated statements of financial condition at their fair value on a recurring basis:
	Available for sale securities – The Company's investment securities classified as available for sale include: mortgage-backed securities, collateralized mortgage obligations, government sponsored enterprise bonds, municipal securities and other debt securities. The fair value of mortgage-backed securities, collateralized mortgage obligations and government sponsored enterprise bonds are determined by a third party valuation source using observable market data utilizing a matrix or multi-dimensional relational pricing model. Standard inputs to these models include observable market data such as benchmark yields, reported trades, broker quotes, issuer spreads, benchmark securities, prepayment models and bid/offer market data. For securities with an early redemption feature, an option adjusted spread model is utilized to adjust the issuer spread. These model and matrix measurements are classified as Level 2 and Level 3 in the fair value hierarchy. The fair value of municipal securities is determined by a third party valuation source using observable market data utilizing a multi-dimensional relational pricing model. Standard inputs to this model include observable market data such as benchmark yields, reported trades, broker quotes, rating updates and issuer spreads. These model measurements are classified as Level 2 in the fair value hierarchy. The fair value of other debt securities, which includes a trust preferred security issued by a financial institution, is determined through quoted prices in active markets and is classified as Level 1 in the fair value hierarchy.
	Loans held for sale – The Company carries loans held for sale at fair value under the fair value option model. Fair value is generally determined by estimating a gross premium or discount, which is derived from pricing currently observable in the secondary market, principally from observable prices for forward sale commitments. Loans held-for-sale are considered to be Level 2 in the fair value hierarchy of valuation techniques.
	Mortgage banking derivatives - Mortgage banking derivatives include interest rate lock commitments to originate residential loans held for sale to individual customers and forward commitments to sell residential mortgage loans to various investors. The Company relies on a valuation model to estimate the fair value of its interest rate lock commitments to originate residential mortgage loans held for sale, which includes applying a pull through rate based upon historical experience and the current interest rate environment and then multiplying by quoted investor prices. The Company also relies on a valuation model to estimate the fair value of its forward commitments to sell residential loans, which includes matching specific terms and maturities of the forward commitments against applicable investor pricing available. While there are Level 2 and 3 inputs used in the valuation models, the Company has determined that one or more of the inputs significant in the valuation of both of the mortgage banking derivatives fall within Level 3 of the fair value hierarchy.
	The table below presents reconciliation for all assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during 2013 and 2012.

_________
(1) Represents collateral-dependent impaired loans, net, which are included in loans.
Loans – We do not record loans at fair value on a recurring basis. On a non-recurring basis, loans determined to be impaired are analyzed to determine whether a collateral shortfall exists, and if such a shortfall exists, are recorded on our consolidated statements of financial condition at net realizable value of the underlying collateral. Fair value is determined based on third party appraisals. Appraised values are adjusted to consider disposition costs and also to take into consideration the age of the most recent appraisal. Given the significance of the adjustments made to appraised values necessary to estimate the fair value of impaired loans, loans that have been deemed to be impaired are considered to be Level 3 in the fair value hierarchy of valuation techniques. At September 30, 2013, loans determined to be impaired with an outstanding balance of $41.8 million were carried net of specific reserves of $6.4 million for a fair value of $35.4 million. At December 31, 2012, loans determined to be impaired with an outstanding balance of $52.5 million were carried net of specific reserves of $12.4 million for a fair value of $40.1 million. Impaired loans collateralized by assets which are valued in excess of the net investment in the loan do not require any specific reserves.
Real estate owned – On a non-recurring basis, real estate owned, is recorded in our consolidated statements of financial condition at the lower of cost or fair value. Fair value is determined based on third party appraisals and, if less than the carrying value of the foreclosed loan, the carrying value of the real estate owned is adjusted to the fair value. Appraised values are adjusted to consider disposition costs and also to take into consideration the age of the most recent appraisal. Given the significance of the adjustments made to appraised values necessary to estimate the fair value of the properties, real estate owned is considered to be Level 3 in the fair value hierarchy of valuation techniques. Changes in the value of real estate owned totaled $1.1 million and $5.5 million during the nine months ended September 30, 2013 and 2012, respectively and are recorded in real estate owned expense. At September 30, 2013 and December 31, 2012, real estate owned totaled $23.1 million and $36.0 million, respectively.
Mortgage servicing rights - The Company utilizes an independent valuation from a third party which uses a discounted cash flow model to estimate the fair value of mortgage servicing rights.  The model utilizes prepayment assumptions to project cash flows related to the mortgage servicing rights based upon the current interest rate environment, which is then discounted to estimate an expected fair value of the mortgage servicing rights.   The model considers characteristics specific to the underlying mortgage portfolio, such as: contractually specified servicing fees, prepayment assumptions, delinquency rates, late charges and costs to service.  Given the significance of the unobservable inputs utilized in the estimation process, mortgage servicing rights are classified as Level 3 within the fair value hierarchy.  The Company records the mortgage servicing rights at the lower of amortized cost or fair value.  At September 30, 2013 and December 31, 2012, there was no impairment identified for mortgage servicing rights, therefore mortgage servicing rights were not recorded at fair value on a non-recurring basis.
For Level 3 assets and liabilities measured at fair value on a recurring or non-recurring basis as of September 30, 2013, the significant unobservable inputs used in the fair value measurements were as follows:
							Significant Unobservable
							Input Value
	Fair Value at			Valuation	Significant		Minimum				Maximum

___________
The significant unobservable inputs used in the fair value measurement of the Company's mortgage banking derivatives, including interest rate lock commitments is the loan pull through rate. This represents the percentage of loans currently in a lock position which the Company estimates will ultimately close. Generally, the fair value of an interest rate lock commitment will be positively (negatively) impacted when the prevailing interest rate is lower (higher) than the interest rate lock commitment. Generally, an increase in the pull through rate will result in the fair value of the interest rate lock increasing when in a gain position, or decreasing when in a loss position. The pull through rate is largely dependent on the loan processing stage that a loan is currently in and the change in prevailing interest rates from the time of the rate lock. The pull through rate is computed using historical data and the ratio is periodically reviewed by the Company.
The significant unobservable inputs used in the fair value measurement of collateral for collateral-dependent impaired loans and real estate owned included in the above table primarily relate to discounting criteria applied to independent appraisals received with respect to the collateral. Discounts applied to the appraisals are dependent on the vintage of the appraisal as well as the marketability of the property. The discount factor is computed using actual realization rates on properties that have been foreclosed upon and liquidated in the open market.
The significant unobservable inputs used in the fair value measurement or mortgage servicing rights include the prepayment rate and note rate.  The prepayment rate represents the assumed rate of prepayment of the outstanding principal balance of the underlying mortgage notes.  Generally, the fair value of mortgage servicing rights will be positively (negatively) impacted when the prepayment rate (decreases) increases.  The note rate represents the contractual rate on the underlying mortgages.
Fair value information about financial instruments follows, whether or not recognized in the consolidated statements of financial condition, for which it is practicable to estimate that value. 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. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. Certain financial instruments and all nonfinancial instruments are excluded from its disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company.
The carrying amounts and fair values of the Company's financial instruments consist of the following:

The following methods and assumptions were used by the Company in determining its fair value disclosures for financial instruments.
Cash and Cash Equivalents
The carrying amount reported in the consolidated statements of financial condition for cash and cash equivalents is a reasonable estimate of fair value.
Securities
The fair value of securities is determined by a third party valuation source using observable market data utilizing a matrix or multi-dimensional relational pricing model. Standard inputs to these models include observable market data such as benchmark yields, reported trades, broker quotes, issuer spreads, benchmark securities and bid/offer market data. For securities with an early redemption feature, an option adjusted spread model is utilized to adjust the issuer spread. Prepayment models are used for mortgage related securities with prepayment features.
Loans Held for Sale
Fair value is estimated using the prices of the Company's existing commitments to sell such loans and/or the quoted market price for commitments to sell similar loans.
Loans Receivable
Loans determined to be impaired are analyzed to determine whether a collateral shortfall exists, and if such a shortfall exists, are recorded on our consolidated statements of financial condition at fair value. Fair value is determined based on third party appraisals. Appraised values are adjusted to consider disposition costs and also to take into consideration the age of the most recent appraisal. With respect to loans that are not considered to be impaired, fair value is estimated by discounting the future contractual cash flows using discount rates that reflect a current rate offered to borrowers of similar credit standing for the remaining term to maturity. This method of estimating fair value does not incorporate the exit-price concept of fair value prescribed by ASC 820-10 and generally produces a higher fair value.
FHLBC Stock
For FHLBC stock, the carrying amount is the amount at which shares can be redeemed with the FHLBC and is a reasonable estimate of fair value.
Cash Surrender Value of Life Insurance
The carrying amounts reported in the consolidated statements of financial condition for the cash surrender value of life insurance approximate those assets' fair values.
Deposits and Advance Payments by Borrowers for Taxes
The fair values for interest-bearing and noninterest-bearing negotiable order of withdrawal accounts, savings accounts, and money market accounts are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates of similar remaining maturities to a schedule of aggregated expected monthly maturities of the outstanding certificates of deposit. The advance payments by borrowers for taxes are equal to their carrying amounts at the reporting date.
Borrowings
Fair values for borrowings are estimated using a discounted cash flow calculation that applies current interest rates to estimated future cash flows of the borrowings.
Accrued Interest Payable and Accrued Interest Receivable
For accrued interest payable and accrued interest receivable, the carrying amount is a reasonable estimate of fair value.
Commitments to Extend Credit and Standby Letters of Credit
Commitments to extend credit and standby letters of credit are generally not marketable. Furthermore, interest rates on any amounts drawn under such commitments would be generally established at market rates at the time of the draw. Fair values for the Company's commitments to extend credit and standby letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements, the counterparty's credit standing, and discounted cash flow analyses. The fair value of the Company's commitments to extend credit is not material at September 30, 2013 and December 31, 2012.
Mortgage Banking Derivative Assets and Liabilities
Mortgage banking derivatives include interest rate lock commitments to originate residential loans held for sale to individual customers and forward commitments to sell residential mortgage loans to various investors. The Company relies on a valuation model to estimate the fair value of its interest rate lock commitments to originate residential mortgage loans held for sale, which includes applying a pull through rate based upon historical experience and the current interest rate environment, and then multiplying by quoted investor prices. The Company also relies on a valuation model to estimate the fair value of its forward commitments to sell residential loans, which includes matching specific terms and maturities of the forward commitments against applicable investor pricing available. On the Company's Consolidated Statements of Condition, instruments that have a positive fair value are included in prepaid expenses and other assets, and those instruments that have a negative fair value are included in other liabilities.

Segments and Related Information	'
	Note 15 – Segment Reporting
	Selected financial and descriptive information is required to be provided about reportable operating segments, considering a "management approach" concept as the basis for identifying reportable segments. The management approach is based on the way that management organizes the segments within the enterprise for making operating decisions, allocating resources, and assessing performance. Consequently, the segments are evident from the structure of the enterprise's internal organization, focusing on financial information that an enterprise's chief operating decision-makers use to make decisions about the enterprise's operating matters. The Company has determined that it has two reportable segments: community banking and mortgage banking. The Company's operating segments are presented based on its management structure and management accounting practices. The structure and practices are specific to the Company and therefore, the financial results of the Company's business segments are not necessarily comparable with similar information for other financial institutions.
	Community Banking
	The Community Banking segment provides consumer and business banking products and services to customers primarily within Southeastern Wisconsin. Consumer products include loan and deposit products: mortgage, home equity loans and lines, personal term loans, demand deposit accounts, interest bearing transaction accounts and time deposits. Business banking products include secured and unsecured lines and term loans for working capital, inventory and general corporate use, commercial real estate construction loans, demand deposit accounts, interest bearing transaction accounts and time deposits.
	Mortgage Banking
	The Mortgage Banking segment provides residential mortgage loans for the purpose of sale on the secondary market. Mortgage banking products and services are provided by offices in: Wisconsin, Arizona, Florida, Idaho, Illinois, Indiana, Iowa, Maryland, Minnesota, Ohio and Pennsylvania.

	Note 16 – Other Matters
	On June 6, 2013, the Boards of Directors of Lamplighter Financial, MHC (the "Mutual Holding Company"), Waterstone Financial, Inc. (the "Company"), and WaterStone Bank SSB (the "Bank") each unanimously adopted the Plan of Conversion and Reorganization of the Mutual Holding Company (the "Plan") pursuant to which the Mutual Holding Company will undertake a "second-step" conversion and cease to exist.
	The Company will merge into a new Maryland corporation named Waterstone Financial, Inc. As part of the conversion, the MHC's ownership interest of the Company will be offered for sale in a public offering. The existing publicly held shares of the Company, which represents the remaining ownership interest in the Company, will be exchanged for new shares of common stock of Waterstone Financial, Inc., the new Maryland corporation. The exchange ratio will ensure that immediately after the conversion and public offering, the public shareholders of the Company will own the same aggregate percentage of Waterstone Financial, Inc. common stock that they owned immediately prior to that time (excluding shares purchased in the stock offering and cash received in lieu of fractional shares). When the conversion and public offering are completed, all of the capital stock of WaterStone Bank will be owned by Waterstone Financial, Inc., the Maryland corporation.
	The Plan provides for the establishment, upon the completion of the conversion, of special "liquidation accounts" for the benefit of certain depositors of WaterStone Bank in an amount equal to the greater of the MHC's ownership interest in the retained earnings of the Company as of the date of the latest balance sheet contained in the prospectus or the retained earnings of WaterStone Bank at the time it reorganized into the MHC. Following the completion of the conversion, under the rules of the Board of Governors of the Federal Reserve System, WaterStone Bank will not be permitted to pay dividends on its capital stock to Waterstone Financial, Inc., its sole shareholder, if WaterStone Bank's shareholder's equity would be reduced below the amount of the liquidation accounts. The liquidation accounts will be reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases will not restore an eligible account holder's interest in the liquidation accounts.
	Direct costs of the conversion and public offering will be deferred and reduce the proceeds from the shares sold in the public offering. Costs of $770,000 have been incurred related to the conversion as of September 30, 2013.

Basis of Presentation [Abstract]	'
Basis of presentation	'
	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles ("GAAP") for interim financial information, Rule 10-01 of Regulation S-X and the instructions to Form 10-Q. The financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring accruals) necessary to present fairly the financial position, results of operations, changes in shareholders' equity, and cash flows of the Company for the periods presented.
Use of estimates	'
	The preparation of the unaudited consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates and assumptions include the allowance for loan losses, deferred income taxes and real estate owned. Actual results could differ from those estimates.

Securities [Abstract]	'
Impairment of investment securities	'
	The Company reviews the investment securities portfolio on a quarterly basis to monitor its exposure to other-than-temporary impairment. In evaluating whether a security's decline in market value is other-than-temporary, management considers the length of time and extent to which the fair value has been less than cost, financial condition of the issuer and the underlying obligors, quality of credit enhancements, volatility of the fair value of the security, the expected recovery period of the security and ratings agency evaluations. In addition the Company may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the value of any underlying collateral. For certain securities in unrealized loss positions, the Company prepares cash flow analyses to compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security.

Derivative Financial Instruments [Abstract]	'
Derivative financial instruments	'
	In connection with its mortgage banking activities, the Company enters into derivative financial instruments as part of its strategy to manage its exposure to changes in interest rates. Mortgage banking derivatives include interest rate lock commitments provided to customers to fund mortgage loans to be sold in the secondary market and forward commitments for the future delivery of such loans to third party investors. It is the Company's practice to enter into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into in order to economically hedge the effect of future changes in interest rates on its commitments to fund the loans as well as on its portfolio of mortgage loans held for sale. The Company's mortgage banking derivatives have not been designated as being in hedge relationships. These instruments are used to manage the Company's exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements of ASC 815. Changes in the fair value of derivatives not designated in hedging relationships are recorded as a component of mortgage banking income in the Company's consolidated statements of operations. The Company does not use derivatives for speculative purposes.
	Forward commitments to sell mortgage loans represent commitments obtained by the Company from a secondary market agency to purchase mortgages from the Company at specified interest rates and within specified periods of time. Commitments to sell loans are made to mitigate interest rate risk on interest rate lock commitments to originate loans and loans held for sale. At September 30, 2013, the Company had forward commitments to sell mortgage loans with an aggregate notional amount of approximately $167.0 million and interest rate lock commitments with an aggregate notional amount of approximately $135.4 million.  The fair value of the forward commitments to sell mortgage loans at September 30, 2013 included a loss of $1.5 million that is reported as a component of other liabilities on the Company's consolidated statement of financial condition. The fair value of the interest rate locks at September 30, 2013 included a gain of $2.7 million that is reported as a component of other assets on the Company's consolidated statements of financial condition.
	In determining the fair value of its derivative loan commitments, the Company considers the value that would be generated by the loan arising from exercise of the loan commitment when sold in the secondary mortgage market. That value includes the price that the loan is expected to be sold for in the secondary mortgage market. The fair value of these commitments is recorded on the consolidated statements of financial condition with the changes in fair value recorded as a component of mortgage banking income.
