WaterStone Bank also has an active mortgage banking subsidiary, Waterstone Mortgage Corporation.</div> <div><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">WaterStone Bank conducts its community banking business from 13 banking offices located in Milwaukee, Washington and Waukesha Counties, Wisconsin, as well as a loan production office in Minneapolis, Minnesota. WaterStone Bank's principal lending activity is originating one- to four-family, multi-family residential real estate, and commercial real estate loans for retention in its portfolio. WaterStone Bank also offers home equity loans and lines of credit, construction and land loans, commercial business loans, and consumer loans. WaterStone Bank funds its loan production primarily with retail deposits and Federal Home Loan Bank advances. Our deposit offerings include: certificates of deposit, money market savings accounts, transaction deposit accounts, non-interest bearing demand accounts and individual retirement accounts. Our investment securities portfolio is comprised principally of mortgage-backed securities, government-sponsored enterprise bonds and municipal obligations.</div> <div><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">WaterStone Bank's mortgage banking operations are conducted through its wholly-owned subsidiary, Waterstone Mortgage Corporation. Waterstone Mortgage Corporation originates single-family residential real estate loans for sale into the secondary market. Waterstone Mortgage Corporation utilizes lines of credit provided by WaterStone Bank as a primary source of funds, and also utilizes a line of credit with another financial institution as needed.</div> <div><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">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.</div> <div style="text-align: left; font-family: 'Times New Roman', Times, serif; font-size: 12pt;"><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 12pt;"><span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">The accompanying unaudited consolidated financial statements and related notes should be read in conjunction with the Company’s December 31, 2019 Annual Report on Form 10-K.

Significant items subject to such estimates and assumptions include the allowance for loan losses, income taxes, and fair value measurements. Actual results could differ from those estimates.</div> <div style="text-align: left; font-family: 'Times New Roman', Times, serif; font-size: 12pt;"><br/></div> <div style="text-align: left; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-style: italic;">Impacts of COVID-19</div> <div><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In March, 2020, the World Health Organization declared the outbreak of COVID-19 as a global pandemic, which continues to spread throughout the United States and around the world. The declaration of a global pandemic indicates that almost all public commerce and related business activities must be, to varying degrees, curtailed with the goal of decreasing the rate of new infections. The outbreak of COVID-19 could adversely impact a broad range of industries in which the Company’s customers operate and impair their ability to fulfill their financial obligations to the Company. On March 3, 2020, the Federal Open Market Committee reduced the target federal funds rate by 50 basis points to 1.00% to 1.25%. This rate was further reduced to a target range of 0% to 0.25% on March 16, 2020. These reductions in interest rates and other effects of the COVID-19 outbreak may adversely affect the Company’s financial condition and results of operations. As a result of the spread of the COVID-19 coronavirus, economic uncertainties have arisen which are likely to negatively impact net interest income and noninterest income. Other financial impact could occur though such potential impacts are unknown at this time.</div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 12pt;"><br/></div> <div style="text-align: left; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-style: italic;">Subsequent Events</div> <div><br/></div> <div style="text-align: justify; margin-right: 5.75pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"><span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">The Company has evaluated subsequent events for potential recognition and/or disclosure through the date the unaudited consolidated financial statements included in this Quarterly Report on Form 10-Q were issued.

These reclassifications did not result in any changes to previously reported net income. The Company reclassified the Cost of Shares Repurchased line item presented in prior periods to the Additional Paid in Capital line item in the Consolidated Statements of Financial Condition. The Cost of Shares Repurchased column was reclassified to the Additional Paid in Capital line in the Consolidated Statements of Changes in Shareholders’ Equity.</div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 12pt;"><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-style: italic;">Impact of Recent Accounting Pronouncements</div> <div><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"><span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-style: italic;">ASC Topic 326 "Financial Instruments - Credit Losses."</span> Authoritative accounting guidance under ASC Topic 326, "Financial Instruments - Credit Losses" amended the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information for credit loss estimates. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The authoritative guidance also requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected (net of the allowance for credit losses). In addition, the credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses rather than a write-down.</div> <div><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was signed into law. It included an option for entities to delay the adoption of ASC Topic 326 until the earlier of the termination date of the national emergency declaration by the President or December 31, 2020. Due to the uncertainty on the economy and unemployment from COVID-19, the Company has determined to delay its adoption of ASC Topic 326 and has calculated and recorded its provision for loan losses under the incurred loss model that existed prior to ASC Topic 326.</div> <div><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">The Company has input the available historical Company data to build an internal model and is reviewing the assumptions to support the calculation under ASC Topic 326. Management’s methodology for estimating the allowance for credit losses under the current expected credit losses (CECL) model includes the use of relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience by vintage classified by loans with similar risk profiles provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are considered for differences in current loan-specific risk characteristics such as changes in underwriting standards, portfolio mix, portfolio volume, delinquency rates, interest rates, or other relevant factors. Management will continue to review and adjust these and other factors. Ongoing evaluations have been performed by vintage adjusted for prepayments. For two portfolio segments, management expects to use a weighted average remaining maturity methodology, which contemplates loss expectations on a pool basis, relying on historic loss rates.</div> <div><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Management is validating the CECL model and methodologies; however we expect an initial increase to the allowance for credit loss, including reserves for unfunded commitments, not to exceed 130% of the December 31, 2019 allowance. When finalized, this one-time increase as a result of the adoption of CECL will be recorded, net of tax, as an adjustment to retained earnings effective on the earlier of the termination date of the national emergency declaration by the President or December 31, 2020. This estimate is subject to change based on continuing refinement and validation of the model and methodologies.</div> <div><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Financial statement users should be aware that the allowance for credit loss is, by design, inherently sensitive to changes in economic outlook, loan and lease portfolio composition, portfolio duration, and other factors.</div> <div><br/></div> <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">As we continue to evaluate the provisions of ASC Topic 326 as of and for the six months ended June 30, 2020, we are considering the following in developing our forecast and its effect on our CECL calculations:</div> <div><br/></div> <table cellpadding="0" cellspacing="0" class="DSPFListTable" id="za281cbd7c3cd44f7ac8b686917d5b0b8" style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; width: 100%; text-align: left; color: #000000;"> <tr> <td style="width: 36pt; vertical-align: top; align: right;"><div style="text-align: left; margin-left: 18pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">•</div></td> <td style="width: auto; vertical-align: top;"><div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Duration, extent and severity of COVID-19;</div></td> </tr> </table> <table cellpadding="0" cellspacing="0" class="DSPFListTable" id="z64be83debfa546788607151541bbf834" style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; width: 100%; text-align: left; color: #000000;"> <tr> <td style="width: 36pt; vertical-align: top; align: right;"><div style="text-align: left; margin-left: 18pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">•</div></td> <td style="width: auto; vertical-align: top;"><div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Effect of government assistance; and</div></td> </tr> </table> <table cellpadding="0" cellspacing="0" class="DSPFListTable" id="z9481a8feeb0d49e29ed51bef687ea25c" style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; width: 100%; text-align: left; color: #000000;"> <tr> <td style="width: 36pt; vertical-align: top; align: right;"><div style="text-align: left; margin-left: 18pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">•</div></td> <td style="width: auto; vertical-align: top;"><div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Unemployment and effect on economies and markets.</div></td> </tr> </table>
