Summary of Significant Accounting Policies
1)Summary of Significant Accounting Policies
 
The following significant accounting and reporting policies of Waterstone Financial, Inc. and subsidiaries (collectively, the "Company"), conform to U.S. generally accepted accounting principles, or ("GAAP"), and are used in preparing and presenting these consolidated financial statements.


(a)      Plan of Conversion and Reorganization
On June 6, 2013, the Board of Directors of Lamplighter Financial, MHC ("MHC") and the Board of Directors of the Waterstone Financial, Inc. ("Waterstone-Federal") adopted a new Plan of Conversion and Reorganization (the "Plan"). Pursuant to the Plan, Waterstone Financial, Inc., a Maryland Corporation, ("New Waterstone") was organized and the MHC converted from the mutual holding company form of organization to the fully public form on January 22, 2014.    As part of the conversion, the MHC's ownership interest of the New Waterstone was offered for sale in a public offering. The existing publicly held shares of the Waterstone-Federal, were exchanged for new shares of common stock of New Waterstone. The exchange ratio ensured that immediately after the conversion and public offering, the public shareholders of the Waterstone-Federal owned the same aggregate percentage of New Waterstone 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 was completed, New Waterstone became the holding company of WaterStone Bank and succeeded to all of the business and operations of Waterstone-Federal and each of Waterstone-Federal and Lamplighter Financial, MHC ceased to exist.
The Plan provided for the establishment of special "liquidation accounts" for the benefit of certain depositors of WaterStoneBank 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 is not 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 $1.4 million have been incurred related to the conversion as of December 31, 2013, and are included in other assets.
Share amounts have been restated to reflect the completion of our second-step conversion on January 22, 2014 at a conversion ratio of 1.0973 unless noted otherwise.


b)Nature of Operations
 
The Company is a one-bank holding company with two operating segments – community banking and mortgage banking.  The Bank is principally engaged in the business of attracting deposits from the general public and using such deposits to originate real estate, business and consumer loans.
 
The Bank provides a full range of financial services to customers through branch locations in southeastern Wisconsin. The Bank is subject to the regulations of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities.
 
The Bank owns a mortgage banking subsidiary that originates residential real estate loans held for sale at various branch offices across the country.  Mortgage banking volume fluctuates widely given movements in interest rates.  Mortgage banking income is reported as a single line item in the statements of operations while mortgage banking expense is distributed among the various noninterest expense lines.  Compensation, payroll taxes and other employee benefits expense varies directly with mortgage banking income.
 
 
c)Principles of Consolidation
 
The consolidated financial statements include the accounts and operations of Waterstone Financial, Inc. and its wholly owned subsidiary, WaterStone Bank.  The Bank has the following wholly owned subsidiaries: Wauwatosa Investments, Inc. and Waterstone Mortgage Corporation. All significant intercompany accounts and transactions have been eliminated in consolidation.
 
d)Use of Estimates
 
The preparation of the 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, valuation of investments, evaluation of other than temporary impairment on investments and valuation of real estate owned. Actual results could differ from those estimates and the current economic environment has increased the degree of uncertainty inherent in those estimates and assumptions.
 
e)Cash and Cash Equivalents
 
The Company considers federal funds sold and highly liquid debt instruments with a maturity of three months or less when purchased to be cash equivalents.
 
f)Securities
 
Available for Sale Securities
 
At the time of purchase, investment securities are classified as available for sale, as management has the intent and ability to hold such securities for an indefinite period of time, but not necessarily to maturity.  Any decision to sell investment securities available for sale would be based on various factors, including, but not limited to asset/liability management strategies, changes in interest rates or prepayment risks, liquidity needs, or regulatory capital considerations.  Available for sale securities are carried at fair value, with the unrealized gains and losses, net of deferred tax, reported as a separate component of equity, accumulated other comprehensive income.  The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity or, in the case of mortgage-backed securities and collateralized mortgage obligations, over the estimated life of the security. Such amortization is included in interest income from securities.  Realized gains or losses on securities sales (using specific identification method) are included in other income.  Declines in value judged to be other than temporary are included in net impairment losses recognized in earnings in the consolidated statements of operations.
 
 
  
Other Than Temporary Impairment
 
One of the significant estimates related to securities is the evaluation of investments for other than temporary impairment.  The Company assesses  investment securities with unrealized loss positions for other than temporary impairment on at least a quarterly basis.  When the fair value of an investment is less than its amortized cost at the balance sheet date of the reporting period for which impairment is assessed, the impairment is designated as either temporary or other than temporary.  In evaluating other than temporary impairment, management considers the length of time and extent to which the fair value has been less than cost and the expected recovery period of the security, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value in the near term.  Declines in the fair value of investment securities below amortized cost are deemed to be other than temporary when the Company cannot assert that it will recover its amortized cost basis, including whether the present value of cash flows expected to be collected is less than the amortized cost basis of the security. If it is more likely than not that the Company will be required to sell the security before recovery or if the Company has the intent to sell, an other than temporary impairment write down is recognized in earnings equal to the difference between the security's amortized cost and its fair value.  If it is not more likely than not that the Company will be required to sell the security before recovery and if the Company does not intend to sell, the other than temporary impairment write down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to other factors, which is recognized as a separate component of equity.  Following the recognition of an other than temporary impairment representing credit loss, the book value of an investment less the impairment loss realized becomes the new cost basis.  Because the Company's assessments are based on factual information as well as subjective information available at the time of assessment, the determination as to whether an other than temporary impairment exists and, if so, the amount considered other than temporarily impaired, or not impaired, is subjective and, therefore, the timing and amount of other than temporary impairments constitute material estimates that are subjective to significant change.
  
Federal Home Loan Bank Stock
 
Federal Home Loan Bank stock is carried at cost, which is the amount that the stock is redeemable by tendering to the FHLBC or the amount at which shares can be sold to other FHLBC members.  FHLBC dividends are recognized as income on their ex-dividend date.
 

g)Loans Held for Sale
 
The origination of residential real estate loans is an integral component of the business of the Company. The Company generally sells its originations of long-term fixed interest rate mortgage loans in the secondary market. Gains and losses on the sales of these loans are determined using the specific identification method. The Company generally sells mortgage loans in the secondary market on a servicing released basis, however, servicing is retained when economic conditions so warrant. Mortgage loans originated for sale are generally sold within 45 days after closing.
 
The Company has elected to carry loans held for sale at fair value.  Fair value is generally determined by estimating a gross premium or discount, which is derived from pricing currently observable in the market.  The amount by which cost differs from market value is accounted for as a valuation adjustment to the carrying value of the loans.  Changes in value are included in mortgage banking income in the consolidated statements of operations.  The carrying value of loans held for sale included a market valuation adjustment of $2.3 million at December 31, 2013 and $6.0 million at December 31, 2012.
 
Costs to originate loans held for sale are expensed as incurred and are included on the appropriate noninterest expense lines of the statements of operations.  Salaries, commissions and related payroll taxes are the primary costs to originate and comprise approximately 73% of total mortgage banking noninterest expense.
 
The value of mortgage loans held for sale and other residential mortgage loan commitments to customers are hedged by utilizing both best efforts and mandatory forward commitments to sell loans to investors in the secondary market. Such forward commitments are generally entered into at the time when applications are taken to protect the value of the mortgage loans from increases in market interest rates during the period held. The Corporation recognizes revenue associated with the expected future cash flows of servicing loans at the time a forward loan commitment is made, as required under Securities and Exchange Commission Staff Accounting Bulletin No. 109, Written Loan Commitments Recorded at Fair Value Through Earnings.

h)Loans Receivable and Related Interest Income
 
Loans are classified as held for investment when management has both the intent and ability to hold the loan for the foreseeable future, or until maturity or payoff.  Loans are carried at the principal amount outstanding, net of any unearned income, charge-offs and unamortized deferred fees and costs.  Loan origination and commitment fees and certain direct loan origination costs are deferred and the net amount amortized as an adjustment of the related loan yield. Amortization is based on a level-yield method over the contractual life of the related loans or until the loan is paid in full.
 
Loan interest income is recognized on the accrual basis.  Accrual of interest is generally discontinued either when reasonable doubt exists as to the full, timely collection of interest or principal, or when a loan becomes contractually past due more than 90 days with respect to interest or principal. At that time, previously accrued and uncollected interest on such loans is reversed and additional income is recorded only to the extent that payments are received and the collection of principal is reasonably assured.  Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectibility of the total contractual principal and interest is no longer in doubt.
  
A loan is accounted for as a troubled debt restructuring if the Company, for economic reasons related to the borrower's financial condition, grants a concession to the borrower that it would not otherwise consider.  A troubled debt restructuring typically involves a modification of terms such as a reduction of the stated interest rate, a deferral of principal payments or a combination of both for a temporary period of time.  If the borrower was performing in accordance with the original contractual terms at the time of the restructuring, the restructured loan is accounted for on an accruing basis as long as the borrower continues to comply with the modified terms.  If the loan was not accounted for on an accrual basis at the time of restructuring, the restructured loan remains in non-accrual status until the loan returns to its original contractual terms and a positive payment history is established.
 

i)Allowance for Loan Losses
 
The allowance for loan losses is presented as a reserve against loans and represents the Bank's assessment of probable loan losses inherent in the loan portfolio.  The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to income.  Estimated loan losses are charged against the allowance when the loan balance is confirmed to be uncollectible directly or indirectly by the borrower or upon initiation of a foreclosure action by the Bank.  Subsequent recoveries, if any, are credited to the allowance.
 
The allowance provides for probable losses that have been identified with specific customer relationships and for probable losses believed to be inherent in the loan portfolio, but have not been specifically identified.  The Bank utilizes its own loss history to estimate inherent losses on loans. Although the Bank allocates portions of the allowance to specific loans and loan types, the entire allowance is available for any loan losses that occur.
 
 
The Bank evaluates the need for specific valuation allowances on loans that are considered impaired. A loan is considered impaired when, based on current information and events, it is probable that the Bank will not be able to collect all amounts due according to the contractual terms of the loan agreement. Within the loan portfolio, all non-accrual loans and loans modified under troubled debt restructurings have been determined by the Bank to meet the definition of an impaired loan.  In addition, other one- to four-family, over four-family, construction and land, commercial real estate and commercial loans may be considered impaired loans.  A valuation allowance is established for an amount equal to the impairment when the carrying amount of the loan exceeds the present value of the expected future cash flows, discounted at the loan's original effective interest rate or the fair value of the underlying collateral.
 
The Bank also establishes valuation allowances based on an evaluation of the various risk components that are inherent in the loan portfolio. The risk components that are evaluated include past loan loss experience; the level of non-performing and classified assets; current economic conditions; volume, growth, and composition of the loan portfolio; adverse situations that may affect the borrower's ability to repay; the estimated value of any underlying collateral; regulatory guidance; and other relevant factors.
 
The appropriateness of the allowance for loan losses is approved quarterly by the Bank's board of directors. The allowance reflects management's best estimate of the amount needed to provide for the probable loss on impaired loans, as well as other credit risks of the Bank, and is based on a risk model developed and implemented by management and approved by the Bank's board of directors.
 
Actual results could differ from this estimate, and future additions to the allowance may be necessary based on unforeseen changes in economic conditions. In addition, federal regulators periodically review the Bank's allowance for loan losses. Such regulators have the authority to require the Bank to recognize additions to the allowance at the time of their examination.
 
j)Real Estate Owned
 
Real estate owned consists of properties acquired through, or in lieu of, loan foreclosure.  Real estate owned is transferred into the portfolio at the lower of estimated fair value less anticipated selling costs based upon the property's appraised value at the date of transfer or the net carrying value of the loan.  To the extent that the net carrying value of the loan exceeds the estimated fair value of the property at the date of transfer, the excess is charged to the allowance for loan losses.  Subsequent write-downs to reflect current fair market value, as well as gains and losses upon disposition and revenue and expenses incurred in maintaining such properties, are treated as period costs and included in real estate owned in the consolidated statements of operations.

 
k)Mortgage Servicing Rights
 
The Company sells residential mortgage loans in the secondary market and, on a selective basis, retains the right to service the loans sold.  Upon sale, a mortgage servicing rights asset is capitalized, which represents the then current fair value of future net cash flows expected to be realized for performing servicing activities.  Mortgage servicing rights, when purchased, are initially recorded at fair value.  Mortgage servicing rights are amortized over the period of estimated net servicing income, and assessed for impairment at each reporting date. Mortgage servicing rights are carried at the lower of the initial capitalized amount, net of accumulated amortization, or estimated fair value, and are included in other assets, net in the consolidated balance sheets.  To the extent that the Company sells mortgage servicing rights, a gain is recognized for the amount of which sale proceeds exceed the remaining unamortized cost of the servicing rights that were sold.  Gains on sale of mortgage serving rights are included in other noninterest income in the consolidated statements of operations.

 
l)Cash Surrender Value of Life Insurance
 
The Company purchased bank owned life insurance on the lives of certain employees.  The Company is the beneficiary of the life insurance policies.  The cash surrender value of life insurance is reported at the amount that would be received in cash if the polices were surrendered.  Increases in the cash value of the policies and proceeds of death benefits received are recorded in non-interest income.  The increase in cash surrender value of life insurance is not subject to income taxes, as long as the Company has the intent and ability to hold the policies until the death benefits are received.
 
m)Office Properties and Equipment
 
Office properties and equipment, including leasehold improvements and software, are stated at cost, net of depreciation and amortization. Depreciation and amortization are computed on the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the lease term, if shorter than the estimated useful life. Maintenance and repairs are charged to expense as incurred, while additions or major improvements are capitalized and depreciated over their estimated useful lives. Estimated useful lives of the assets are 10 to 30 years for office properties, 3 to 10 years for equipment, and 3 years for software. Rent expense related to long-term operating leases is recorded on the accrual basis.
 
n)Income Taxes
 
The Company and its subsidiaries file consolidated federal and combined state income tax returns. The provision for income taxes is based upon income in the consolidated financial statements, rather than amounts reported on the income tax returns.  Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, as well as net operating loss carry fowards.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date.  
 
The Company evaluates the realizability of its deferred tax assets on a quarterly basis.  Under generally accepted accounting principles, a valuation allowance is required to be recognized if it is "more likely than not" that a deferred tax asset will not be realized.  The determination of the realizability of the deferred tax assets is highly subjective and dependent upon judgment concerning management's evaluation of both positive and negative evidence, the forecasts of future income, applicable tax planning strategies, and assessments of current and future economic and business conditions.

Positions taken in the Company's tax returns may be subject to challenge by the taxing authorities upon examination.  The benefit of uncertain tax positions are initially recognized in the financial statements only when it is more likely than not the position will be sustained upon examination by the tax authorities.  Such tax positions are both initially and subsequently measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement with the tax authority, assuming full knowledge of the position and all relevant facts.   Interest and penalties on income tax uncertainties are classified within income tax expense in the income statement.

o)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 shareholders by the weighted average number of common shares outstanding during the applicable period, excluding outstanding participating securities.  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.  Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.  Shares of the Employee Stock Ownership Plan committed to be released are considered outstanding for both common and diluted EPS.  Incentive stock compensation awards granted can result in dilution.
 

p)Comprehensive Income
 
Comprehensive income is the total of reported net income and changes in unrealized gains or losses, net of tax, on securities available for sale.
 
q)Employee Stock Ownership Plan (ESOP)
 
Compensation expense under the ESOP is equal to the fair value of common shares released or committed to be released to participants in the ESOP in each respective period.  Common stock purchased by the ESOP and not committed to be released to participants is included in the consolidated statements of financial condition at cost as a reduction of shareholders' equity.
  
r)Impact of Recent Accounting Pronouncements
 
In January 2013, the Financial Accounting Standards Board ("FASB") issued ASU No. 2013-01, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities, which amended disclosures by requiring improved information about financial instruments and derivative instruments that are either offset on the balance sheet or subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset on the balance sheet. Reporting entities are required to provide both net and gross information for these assets and liabilities in order to enhance comparability between those entities that prepare their financial statements on the basis of international financial reporting standards ("IFRS"). Companies were required to apply the amendments for fiscal years beginning on or after January 1, 2013, and interim periods within those years.  The adoption of this accounting standard did not have a material impact on the Company's results of operation, financial position, or liquidity.

In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.  Under this standard, an entity is required to provide information about the amounts reclassified out of accumulated OCI by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of accumulated OCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. This standard does not change the current requirements for reporting net income or other comprehensive income in the financial statements and was effective for interim and annual periods beginning on or after December 15, 2012. The adoption of this accounting standard did not have a material impact on the Company's results of operation, financial position, or liquidity.

In January 2014, the FASB issued ASU No. 2014-04, "Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure."  This ASU clarifies 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 agreement. In addition, the amendment requires interim and annual disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure in accordance with local requirements of the applicable jurisdiction. This amendment is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. An entity can elect to adopt the amendments using either a modified retrospective method or a prospective transition method. Early adoption is permitted. The Company is in the process of evaluating the impact of this standard to its results of operations, financial position, or liquidity.

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 did not 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.
