Waterstone Financial, Inc.

Waterstone Financial, Inc., a Maryland corporation ("New Waterstone"), was organized in June 2013.  Upon completion of the mutual-to-stock conversion of Lamplighter Financial, MHC in January 2014, New Waterstone became the holding company of WaterStone Bank SSB and succeeded to all of the business and operations of Waterstone Financial, Inc., a Federal corporation ("Waterstone-Federal") and each of Waterstone-Federal and Lamplighter Financial, MHC ceased to exist.  In this report, we refer to WaterStone Bank SSB, our wholly owned subsidiary, both before and after the reorganization, as "WaterStone Bank" or the "Bank."

New Waterstone did not engage in any business prior to the completion of the mutual-to-stock conversion of Lamplighter Financial, MHC on January 22, 2014. Consequently, this Annual Report on Form 10-K reflects the financial condition and operating results of Waterstone-Federal and its subsidiaries, including the Bank, until January 22, 2014, and of New Waterstone, and its subsidiaries, including the Bank, thereafter. The words "Waterstone Financial," "we" and "our" thus are intended to refer to Waterstone-Federal and its subsidiaries with respect to matters and time periods occurring on or before January 22, 2014, and to New Waterstone and its subsidiaries with respect to matters and time periods occurring thereafter.

Waterstone Financial, Inc. and its subsidiaries, including WaterStone Bank, are referred to herein as the "Company," "Waterstone Financial," or "we."

BUSINESS OF WATERSTONE BANK

General

WaterStone Bank is a community bank that has served the banking needs of its customers since 1921. WaterStone Bank also has an active mortgage banking subsidiary, Waterstone Mortgage Corporation, which had 81 offices in 24 states as of December 31, 2017.

WaterStone Bank conducts its community banking business from 11 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, and commercial real estate loans for retention in its portfolio. At December 31, 2017, such loans comprised 34.0%, 44.8%, and 15.2%, respectively, of WaterStone Bank's loan 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, municipal obligations, and other debt securities.

WaterStone Bank is subject to comprehensive regulation and examination by the Wisconsin Department of Financial Institutions (the "WDFI") and the Federal Deposit Insurance Corporation (the "FDIC").

WaterStone Bank's executive offices are located at 11200 West Plank Court, Wauwatosa, Wisconsin 53226, and its telephone number is (414) 761-1000.  Its website address is www.wsbonline.com.

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.  On a consolidated basis, Waterstone Mortgage Corporation originated approximately $2.46 billion in mortgage loans held for sale during the year ended December 31, 2017, which excludes the loans originated from Waterstone Mortgage Corporation and purchased by WaterStone Bank.

Market Area

WaterStone Bank.  WaterStone Bank's market area is broadly defined as the Milwaukee, Wisconsin metropolitan market, which is geographically located in the southeast corner of the state.  WaterStone Bank's primary market area is Milwaukee and Waukesha counties and the five surrounding counties of Ozaukee, Washington, Jefferson, Walworth and Racine. We have six branch offices in Milwaukee County, four branch offices in Waukesha County and one branch office in Washington County.  At June 30, 2017 (the latest date for which information was publicly available), 49.5% of deposits in the State of Wisconsin were located in the seven-county Milwaukee metropolitan market and 43.9% of deposits in the State of Wisconsin were located in the three counties in which the Bank has a branch office.

WaterStone Bank's primary market area for deposits includes the communities in which we maintain our banking office locations. Our primary lending market area is broader than our primary deposit market area and includes all of the primary market area noted above but extends further west to the Madison, Wisconsin market and further north to the Appleton and Green Bay, Wisconsin markets. Additionally, in 2013 we opened a loan production office in Minneapolis, Minnesota, which has a primary lending market area of the Minneapolis-St. Paul, Minnesota metropolitan market.

Waterstone Mortgage Corporation.  As of December 31, 2017, Waterstone Mortgage Corporation had 15 offices in Wisconsin, 11 offices in Florida, nine offices in Pennsylvania, six offices in each of Minnesota and Ohio, three offices in each of California, Indiana, Maryland, Michigan and Texas, two offices in each of Arizona, Iowa, Illinois, Oregon, and Virginia, and one office in each of Alabama, Colorado, Delaware, Georgia, Idaho, Maine, Massachusetts, New Hampshire, and Tennessee.

Competition

WaterStone Bank.  WaterStone Bank faces competition within our market area both in making real estate loans and attracting deposits. The Milwaukee-Waukesha-West Allis metropolitan statistical area has a high concentration of financial institutions, including large commercial banks, community banks and credit unions. As of June 30, 2017, based on the FDIC annual Summary of Deposits Report, we had the tenth largest market share in our metropolitan statistical area out of 47 financial institutions, representing 1.39% of all deposits.

Our competition for loans and deposits comes principally from commercial banks, savings institutions, mortgage banking firms and credit unions. We face additional competition for deposits from money market funds, brokerage firms, and mutual funds. Some of our competitors offer products and services that we do not offer, such as trust services and private banking.

Our primary focus is to build and develop profitable consumer and commercial customer relationships while maintaining our role as a community bank.

Waterstone Mortgage Corporation.  Waterstone Mortgage Corporation faces competition for originating loans both directly within the markets in which it operates and from entities that provide services throughout the United States through internet services.  Waterstone Mortgage Corporation's competition comes principally from other mortgage banking firms, as well as from commercial banks, savings institutions and credit unions.

Lending Activities

 The scope of the discussion included under "Lending Activities" is limited to lending operations related to loans originated for investment.  A discussion of the lending activities related to loans originated for sale is included under "Mortgage Banking Activities."

 Historically, our principal lending activity has been originating mortgage loans for the purchase or refinancing of residential real estate. Generally, we retain the loans that we originate, which we refer to as loans originated for investment. One- to four-family residential mortgage loans represented $439.6 million, or 34.0%, of our total loan portfolio at December 31, 2017.  Multi-family residential mortgage loans represented $578.4 million, or 44.8%, of our total loan portfolio at December 31, 2017.  We also offer construction and land loans, commercial real estate loans, home equity lines of credit and commercial loans.  At December 31, 2017, commercial real estate loans, commercial business loans, home equity loans, and land and construction loans totaled $195.8 million, $36.7 million, $21.1 million and $19.9 million, respectively.

Loan Portfolio Composition.  The following table sets forth the composition of our loan portfolio in dollar amounts and as a percentage of the total portfolio at the dates indicated.

·          

The following table sets forth the scheduled repayments of fixed and adjustable rate loans at December 31, 2017 that are contractually due after December 31, 2018.

One- to Four-Family Residential Mortgage Loans.  One- to four-family residential mortgage loans totaled $439.6 million, or 34.0% of total loans at December 31, 2017.  One- to four-family residential mortgage loans originated for investment during the year ended December 31, 2017 totaled $117.7 million, or 37.4% of all loans originated for investment. Our one- to four-family residential mortgage loans have fixed or adjustable rates.  Our single family adjustable-rate mortgage loans generally provide for maximum annual rate adjustments of 200 basis points, with a lifetime maximum adjustment of 600 basis points.  Our adjustable-rate mortgage loans typically amortize over terms of up to 30 years, and are indexed to the 12-month LIBOR rate.  Single family adjustable rate mortgage loans are originated at both our community banking segment and our mortgage banking segment.   We do not and have never offered residential mortgage loans specifically designed for borrowers with sub-prime credit scores, including Alt-A and negative amortization loans.  Further, prior to 2007, we did not offer indexed, adjustable-rate loans other than home equity lines of credit, and we have never offered "teaser rate" first mortgage products.

 

Adjustable rate mortgage loans can decrease the interest rate risk associated with changes in market interest rates by periodically repricing, but involve other risks because, as interest rates increase, the loan payments by the borrower increase, thus increasing the potential for default by the borrower. At the same time, the marketability of the underlying collateral may be adversely affected by higher interest rates. Upward adjustment of the contractual interest rate is also limited by the maximum periodic and lifetime interest rate adjustments permitted by our loan documents and, therefore, the effectiveness of adjustable rate mortgage loans in decreasing the risk associated with changes in interest rates may be limited during periods of rapidly rising interest rates. Moreover, during periods of rapidly declining interest rates the interest income received from the adjustable rate loans can be significantly reduced, thereby adversely affecting interest income.

All residential mortgage loans that we originate include "due-on-sale" clauses, which give us the right to declare a loan immediately due and payable in the event that, among other things, the borrower sells or otherwise transfers the real property subject to the mortgage and the loan is not repaid.  We also require homeowner's insurance and where circumstances warrant, flood insurance, on properties securing real estate loans.  The average one- to four-family first mortgage loan balance was $201,000 on December 31, 2017, and the largest outstanding balance on that date was $4.5 million, which is a consolidation loan that is collateralized by 29 properties.  A total of 78.7% of our one- to four-family loans are collateralized by properties in the state of Wisconsin.

A multi-family borrower's financial information is monitored on an ongoing basis by requiring periodic financial statement updates, payment history reviews and periodic face-to-face meetings with the borrower.  We generally require borrowers with aggregate outstanding balances exceeding $1.0 million to provide updated financial statements and federal tax returns annually.  These requirements also apply to all guarantors on these loans.  We also require borrowers with rental investment property to provide an annual report of income and expenses for the property, including a tenant list and copies of leases, as applicable.  The average outstanding multi-family mortgage loan balance was $890,000 on December 31, 2017, with the largest outstanding balance at $13.7 million.  At December 31, 2017, our largest exposure to one multi-family borrower or to a related group of borrowers was $36.2 million.

Loans secured by multi-family real estate generally involve larger principal amounts than owner-occupied, one- to four-family residential mortgage loans. Because payments on loans secured by multi-family properties often depend on the successful operation or management of the properties, repayment of such loans may be affected by adverse conditions in the real estate market or the economy.

Home Equity Loans and Lines of Credit. We also offer home equity loans and home equity lines of credit, both of which are secured by owner-occupied and non-owner occupied one- to four-family residences.  At December 31, 2017, outstanding home equity loans and equity lines of credit totaled $21.1 million, or 1.6% of total loans outstanding.  At December 31, 2017, the unadvanced portion of home equity lines of credit totaled $15.0 million.  Home equity loans and lines originated for investment during the year ended December 31, 2017 totaled $5.4 million, or 1.7% of all loans originated for investment.  The underwriting standards utilized for home equity loans and home equity lines of credit include a determination of the applicant's credit history, an assessment of the applicant's ability to meet existing obligations and payments on the proposed loan, and the value of the collateral securing the loan.  Home equity loans are offered with adjustable rates of interest and with terms up to 10 years.  The loan-to-value ratio for our home equity loans and our lines of credit is generally limited to 90% when combined with the first security lien, if applicable.  Our home equity lines of credit have ten-year terms and adjustable rates of interest, subject to a contractual floor, which are indexed to the prime rate, as reported in The Wall Street Journal.  Interest rates on home equity lines of credit are generally limited to a maximum rate of 18%.  The average outstanding home equity loan balance was $42,000 at December 31, 2017, with the largest outstanding balance at that date of $563,000.

Construction and Land Loans.  We originate construction loans for the acquisition of land and the construction of single-family residences, multi-family residences, and commercial real estate buildings.  At December 31, 2017, construction and land loans totaled $19.9 million, or 1.5% of total loans.  Construction and land loans originated for investment during the year ended December 31, 2017 totaled $2.3 million, or 0.7% of all loans originated for investment.  At December 31, 2017, the unadvanced portion of these construction loans totaled $17.1 million.

Before making a commitment to fund a construction loan, we require an appraisal of the property by an independent licensed appraiser. We also review and inspect each property before disbursement of funds during the term of the construction loan. Loan proceeds are disbursed after inspection based on either the percentage of completion method or the actual cost of the completed work.

Construction financing is generally considered to involve a higher degree of credit risk than longer-term financing on improved, owner-occupied real estate. Risk of loss on a construction loan depends largely upon the accuracy of the initial estimate of the value of the property at completion of construction compared to the estimated cost (including interest) of construction and other assumptions. If the estimate of construction cost is inaccurate, we may be required to advance funds beyond the amount originally committed in order to protect the value of the property. Additionally, if the estimate of value is inaccurate, we may be confronted with a project, when completed, with a value that is insufficient to ensure full repayment of the loan.

Commercial Real Estate Loans.  Commercial real estate loans totaled $195.8 million at December 31, 2017, or 15.2% of total loans, and are made up of loans secured by office and retail buildings, industrial buildings, churches, restaurants, other retail properties and mixed use properties. Commercial real estate loans originated for investment during the year ended December 31, 2017 totaled $61.7 million, or 19.6% of all loans originated for investment. These loans are generally secured by property located in our primary market area. Our commercial real estate underwriting policies provide that such real estate loans may be made in amounts of up to 80% of the appraised value of the property. Commercial real estate loans are offered with interest rates that are fixed up to five years or are variable and either adjust based on a market index or at our discretion. Contractual maturities do not exceed 10 years while principal and interest payments are typically based on a 25-30-year amortization period. In reaching a decision whether to make a commercial real estate loan, we consider gross revenues and the net operating income of the property, the borrower's expertise and credit history, business and global cash flow, and the appraised value of the underlying property. In addition, we will also consider the terms and conditions of the leases and the credit quality of the tenants, if applicable. We generally require that the properties securing these real estate loans have debt service coverage ratios (the ratio of earnings before interest, income taxes, depreciation and amortization divided by interest expense and current maturities of long term debt) of at least 1.15 times. Environmental surveys are required for commercial real estate loans when environmental risks are identified. Generally, commercial real estate loans made to corporations, partnerships and other business entities require personal guarantees by the principals and by the owners of 20% or more of the borrower.

A commercial real estate borrower's financial information is monitored on an ongoing basis by requiring periodic financial statement updates, payment history reviews and periodic face-to-face meetings with the borrower.  We generally require borrowers with aggregate outstanding balances exceeding $1.0 million to provide annual updated financial statements and federal tax returns.  These requirements also apply to all guarantors on these loans.  We also require borrowers to provide an annual report of income and expenses for the property, including a tenant list and copies of leases, as applicable.  The average commercial real estate loan in our portfolio at December 31, 2017 was $816,000, and the largest outstanding balance at that date was $8.9 million.

Commercial Loans.  Commercial loans totaled $36.7 million at December 31, 2017, or 2.8% of total loans, and are made up of loans secured by accounts receivable, inventory, equipment and real estate. Commercial loans originated for investment during the year ended December 31, 2017 totaled $19.6 million, or 6.2% of all loans originated.

Our commercial loans are generally made to borrowers that are located in our primary market area.  Working capital lines of credit are granted for the purpose of carrying inventory and accounts receivable or purchasing equipment.  These lines require that certain collateral levels must be maintained and are monitored on a monthly or quarterly basis.  Working capital lines of credit are short-term loans of 12 months or less with variable interest rates.  At December 31, 2017, the unadvanced portion of working capital lines of credit totaled $16.9 million.  Outstanding balances fluctuate up to the maximum commitment amount based on fluctuations in the balance of the underlying collateral.  Personal property loans secured by equipment are considered commercial business loans and are generally made for terms of up to 84 months and for up to 80% of the value of the underlying collateral.  Interest rates on equipment loans may be either fixed or variable.  Commercial business loans are generally variable rate loans with initial fixed rate periods of up to five years.

A commercial business borrower's financial information is monitored on an ongoing basis by requiring periodic financial statement updates, usually quarterly, payment history reviews and periodic face-to-face meetings with the borrower. The average outstanding commercial loan at December 31, 2017 was $234,000 and the largest outstanding balance on that date was $6.7 million.

The following table shows loan origination, principal repayment activity, transfers to real estate owned, charge-offs and sales during the years indicated.

Origination and Servicing of Loans.  All loans originated for investment are underwritten pursuant to internally developed policies and procedures.  While we generally underwrite owner-occupied residential mortgage loans to Freddie Mac and Fannie Mae standards, due to several unique characteristics, our loans originated prior to 2008 do not conform to the secondary market standards.  The unique features of these loans include interest payments in advance of the month in which they are earned and discretionary rate adjustments that are not tied to an independent index.

Exclusive of our mortgage banking operations, we retain in our portfolio all of the loans that we originate. At December 31, 2017, WaterStone Bank was not servicing any loan it originated and subsequently sold to unrelated third parties. Loan servicing includes collecting and remitting loan payments, accounting for principal and interest, contacting delinquent mortgagors, supervising foreclosures and property dispositions in the event of unremedied defaults, making certain insurance and tax payments on behalf of the borrowers and generally administering the loans.

Loan Approval Procedures and Authority.  WaterStone Bank's lending activities follow written, non-discriminatory, underwriting standards and loan origination procedures established by WaterStone Bank's board of directors.  The loan approval process is intended to assess the borrower's ability to repay the loan, the viability of the loan and the adequacy of the value of the property that will secure the loan, if applicable.  To assess the borrower's ability to repay, we review the employment and credit history and information on the historical and projected income and expenses of borrowers.

Loan officers, with concurrence from independent credit officers and underwriters, are authorized to approve and close any loan that qualifies under WaterStone Bank underwriting guidelines within the following lending limits:

Asset Quality

When a loan becomes more than 30 days delinquent, WaterStone Bank sends a letter advising the borrower of the delinquency.  The borrower is given a specific date by which delinquent payments must be made or by which they must contact WaterStone Bank to make arrangements to bring the loan current over a longer period of time.  If the borrower fails to bring the loan current within the specified time period or to make arrangements to cure the delinquency over a longer period of time, the matter is referred to legal counsel and foreclosure or other collection proceedings are considered.

All loans are reviewed on a regular basis, and loans are placed on non-accrual status when they become 90 or more days delinquent. When loans are placed on non-accrual status, unpaid accrued interest is reversed, and further income is recognized only to the extent received when collection of the remaining principal balance is reasonably assured.

Non-Performing Assets.  Non-performing assets consist of non-accrual loans and other real estate owned.  Loans are generally placed on non-accrual status when contractually past due 90 days or more as to interest or principal payments.  Additionally, whenever management becomes aware of facts or circumstances that may adversely impact the collectability of principal or interest on loans, management may place such loans on non-accrual status immediately, rather than waiting until the loan becomes 90 days past due. At the time a loan is placed on non-accrual status, 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 collectability of the total contractual principal and interest is no longer in doubt.

The table below sets forth the amounts and categories of our non-accrual loans and real estate owned at the dates indicated.

All loans that meet or exceed 90 days with respect to past due principal and interest are recognized as non-accrual. Troubled debt restructurings which are still on non-accrual status either due to being past due 90 days or greater, or which have not yet performed under the modified terms for a reasonable period of time, are included in the table above. In addition, loans which are past due less than 90 days are evaluated to determine the likelihood of collectability given other credit risk factors such as early stage delinquency, the nature of the collateral or the results of a borrower fiscal review. When the collection of all contractual principal and interest is determined to be unlikely, the loan is moved to non-accrual status and an updated appraisal of the underlying collateral is ordered. This process generally takes place between contractual past due dates 60 and 90 days. Upon determining the updated estimated value of the collateral, a loan loss provision is recorded to establish a specific reserve to the extent that the outstanding principal balance exceeds the updated estimated net realizable value of the collateral. When a loan is determined to be uncollectible, generally coinciding with the initiation of foreclosure action, the specific reserve is reviewed for adequacy, adjusted if necessary, and charged-off.

The following table sets forth activity in our non-accrual loans for the years indicated.

Total non-accrual loans decreased by $3.8 million, or 38.4%, to $6.1 million as of December 31, 2017 compared to $9.9 million as of December 31, 2016.  The ratio of non-accrual loans to total loans receivable was 0.47% at December 31, 2017 compared to 0.84% at December 31, 2016.  During the year ended December 31, 2017, $2.2 million were transferred to real estate owned, $766,000 in loan principal was charged off, $1.3 million in principal payments were received and $2.7 million in loans were returned to accrual status. Offsetting this activity, $3.1 million in loans were placed on non-accrual status during the year ended December 31, 2017.

Of the $6.1 million in total non-accrual loans as of December 31, 2017, $5.4 million in loans have been specifically reviewed to assess whether a specific valuation allowance is necessary.  A specific valuation allowance is established for an amount equal to the impairment when the carrying value of the loan exceeds the present value of expected future cash flows, discounted at the loan's original effective interest rate or the fair value of the underlying collateral with an adjustment made for costs to dispose of the asset.  Based upon these specific reviews, a total of $1.8 million in partial charge-offs have been recorded with respect to these loans as of December 31, 2017. Partially charged-off loans measured for impairment based upon net realizable collateral value are maintained in a "non-performing" status and are disclosed as impaired loans.  In addition, specific reserves totaling $124,000 have been recorded as of December 31, 2017.  The remaining $630,000 of non-accrual loans were reviewed on an aggregate basis and $126,000 in general valuation allowance was deemed necessary related to those loans as of December 31, 2017.   The $126,000 in general valuation allowance is based upon a migration analysis performed with respect to similar non-accrual loans in prior periods.

The outstanding principal balance of our five largest non-accrual loans as of December 31, 2017 totaled $1.9 million, which represents 31.9% of total non-accrual loans as of that date.  These five loans are carried net of cumulative life-to-date charge-offs of $15,000.  Aggregate specific valuation allowances with respect to these five loans total $6,000 as of December 31, 2017.

For the year ended December 31, 2017, gross interest income that would have been recorded had our non-accruing loans been current in accordance with their original terms was $480,000.  We received $407,000 of interest payments on such loans during the year ended December 31, 2017. 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.

There were no accruing loans past due 90 days or more during the years ended December 31, 2017, 2016 or 2015.

Troubled Debt Restructurings.  The following table summarizes troubled debt restructurings by the Company's internal risk rating.

Troubled debt restructurings totaled $5.1 million at December 31, 2017, compared to $10.1 million at December 31, 2016. At December 31, 2017, $4.4 million of troubled debt restructurings, or 87.0%, were performing in accordance with their restructured terms. All troubled debt restructurings are considered to be impaired and are risk rated as either substandard or watch and are included in the internal risk rating tables disclosed in the notes to the consolidated financial statements. Specific reserves have been established to the extent that the collateral-based impairment analyses indicate that a collateral shortfall exists or to the extent that a discounted cash flow analysis results in an impairment.

We do not participate in government-sponsored troubled debt restructuring programs.  Our troubled debt restructurings are short-term modifications.  Typical initial restructured terms include six to twelve months of principal forbearance, a reduction in interest rate or both.  Restructured terms do not include a reduction of the outstanding principal balance unless mandated by a bankruptcy court. Troubled debt restructuring terms may be renewed or further modified at the end of the initial term for an additional period if performance has been acceptable and the short-term borrower difficulty persists.

Information with respect to the accrual status of our troubled debt restructurings is provided in the following table.

The following table sets forth activity in our troubled debt restructurings for the years indicated.

For the year ended December 31, 2017, gross interest income that would have been recorded had our troubled debt restructurings been current in accordance with their contractual terms was $347,000.  We received $313,000 of interest payments on such loans during the year ended December 31, 2017. Interest payments received on non-accrual troubled debt restructurings 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.

If a restructured loan is current in all respects and a minimum of six consecutive restructured payments have been received, it can be considered for return to accrual status.  After a restructured loan that is current in all respects reverts to contractual/market terms, if a credit department review indicates no evidence of elevated market risk, the loan is removed from the troubled debt restructuring classification.

Loan Delinquency.  The following table summarizes loan delinquency in total dollars and as a percentage of the total loan portfolio:

Past due loans decreased by $2.3 million, or 28.6%, to $5.9 million at December 31, 2017 from $8.2 million at December 31, 2016.  Loans past due 90 days or more decreased by $1.3 million, or 24.9%, during the year ended December 31, 2017 and loans past due less than 90 days decreased by $1.0 million, or 35.5%.  The $1.3 million decrease in loans past due 90 days or more was primarily due to a decrease in the one- to four-family real estate loans of $1.1 million during the year ended December 31, 2017.  The $1.0 million decrease in loans past due less than 90 days was primarily due to a decrease in the one- to four-family real estate loans of $1.1 million during the year ended December 31, 2017.

Potential Problem Loans.  We define potential problem loans as substandard loans which are still accruing interest.  We do not necessarily expect to realize losses on potential problem loans, but we recognize potential problem loans carry a higher probability of default and require additional attention by management.  The aggregate principal amounts of potential problem loans as of December 31, 2017 and 2016 were $5.5 million and $5.6 million, respectively.  Management believes it has established an adequate allowance for probable loan losses as appropriate under generally accepted accounting principles.

Real Estate Owned.

Total real estate owned decreased by $1.6 million, or 25.5%, to $4.6 million at December 31, 2017, compared to $6.1 million at December 31, 2016.  During the year ended December 31, 2017, $2.2 million was transferred from loans to real estate owned upon completion of foreclosure. During the same period, sales of real estate owned totaled $3.2 million. Write-downs totaled $514,000 during the year ended December 31, 2017.

 New appraisals received on real estate owned and collateral dependent impaired loans are based upon an "as is value" assumption.  During the period of time in which we are awaiting receipt of an updated appraisal, loans evaluated for impairment based upon collateral value are measured by the following:

● Applying an updated adjustment factor to an existing appraisal;

● Confirming that the physical condition of the real estate has not significantly changed since the last valuation date;

● Comparing the estimated current value of the collateral to that of updated sales values experienced on similar collateral;

● Comparing the estimated current value of the collateral to that of updated values seen on current appraisals of similar collateral; and

● Comparing the estimated current value to that of updated listed sales prices on our real estate owned and that of similar properties (not owned by the Company).

We owned 33 properties at December 31, 2017, compared to 30 properties as of December 31, 2016 and 69 properties at December 31, 2015.  Habitable real estate owned is managed with the intent of attracting a lessee to generate revenue. Foreclosed properties are transferred to real estate owned at estimated net realizable value, with charge-offs, if any, charged to the allowance for loan losses upon transfer to real estate owned.  The fair value is primarily based upon updated appraisals in addition to an analysis of current real estate market conditions.

Allowance for Loan Losses

We establish valuation allowances on loans that are deemed to be impaired. A loan is considered impaired when, based on current information and events, it is probable that we will not be able to collect all amounts due according to the contractual terms of the loan agreement. 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.

We also establish 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 allowance is increased by provisions charged to earnings and recoveries of previously charged-off loans and reduced by charge-offs. The appropriateness of the allowance for loan losses is reviewed and approved quarterly by the WaterStone Bank board of directors. The allowance reflects management's best estimate of the amount needed to provide for the probable loss on impaired loans and other inherent losses in the loan portfolio, and is based on a risk model developed and implemented by management and approved by the WaterStone Bank board of directors.

Actual results could differ from this estimate, and future additions to the allowance may be necessary based on unforeseen changes in loan quality and economic conditions. In addition, the Federal Deposit Insurance Corporation and the WDFI, as an integral part of their examination process, periodically review WaterStone Bank's allowance for loan losses. Such regulators have the authority to require WaterStone Bank to recognize additions to the allowance based on their judgments of information available to them at the time of their review or examination.

Any loan that is 90 or more days past due is placed on non-accrual and classified as a non-performing loan. A loan is classified as impaired when it is probable that we will be unable to collect all amounts due in accordance with the terms of the loan agreement. Non-performing loans are then evaluated and accounted for in accordance with generally accepted accounting principles.

The following table sets forth activity in our allowance for loan losses for the years indicated.

Allocation of Allowance for Loan Losses.  The following table sets forth the allowance for loan losses allocated by loan category, the total loan balances by category, and the percent of loans in each category to total loans at the dates indicated. The allowance for loan losses allocated to each category is not necessarily indicative of future losses in any particular category and does not restrict the use of the allowance to absorb losses in other categories.

All impaired loans meeting the criteria established by management are evaluated individually, based primarily on the value of the collateral securing each loan and the ability of the borrowers to repay according to the terms of the loans, or based upon an analysis of the present value of the expected future cash flows under the original contract terms as compared to the modified terms in the case of certain troubled debt restructurings.  Specific loss allowances are established as required by this analysis.  At least once each quarter, management evaluates the appropriateness of the balance of the allowance for loan losses based on several factors some of which are not loan specific, but are reflective of the inherent losses in the loan portfolio.  This process includes, but is not limited to, a periodic review of loan collectability in light of historical experience, the nature and volume of loan activity, conditions that may affect the ability of the borrower to repay, underlying value of collateral and economic conditions in our immediate market area.  All loans for which a specific loss review is not required are segregated by loan type and a loss allowance is established by using loss experience data and management's judgment concerning other matters it considers significant including trends in non-performing loan balances, impaired loan balances, classified asset balances and the current economic environment.  The allowance is allocated to each category of loans based on the results of the above analysis.

The above analysis is both quantitative and subjective, as it requires us to make estimates that are susceptible to revisions as more information becomes available. Although we believe that we have established the allowance at levels appropriate to absorb probable and estimable losses, additions may be necessary if future economic conditions differ substantially from the current environment.

At December 31, 2017, the allowance for loan losses was $14.1 million, compared to $16.0 million at December 31, 2016.  As of December 31, 2017, the allowance for loan losses to total loans receivable was 1.09% and  231.99% of non-performing loans, compared to 1.36%, and 162.62%, respectively at December 31, 2016.  The decrease in the allowance for loan losses during the year ended December 31, 2017 reflects a continued stabilization in both the quality of the loan portfolio as well as the overall local real estate market.  During the periods ended December 31, 2017 and 2016, we experienced a stabilization or improvement in a number of key loan-related loan quality metrics, including impaired loans, substandard loans, watch loans, charge-offs, loans contractually past due and non-accrual loans.

Net charge-offs totaled $786,000, or 0.06% of average loans for the year ended December 31, 2017, compared to $536,000, or a 0.05% of average loans for the year ended December 31, 2016.  The $250,000 increase in net charge-offs was primarily the result of an increase in charge-offs in the one- to four-family loan category offset primarily by decreases in the multi-family, home equity, and construction and land loan categories.  Net charge-offs related to loans secured by one- to four-family residential loans increased $879,000, or 457.8%, to $1.1 million for year ended December 31, 2017, as compared to $192,000 for the year ended December 31, 2016. Partially offsetting the increase, net charge-offs related to loans secured by multi-family residential loans decreased $453,000, or 134.4%, to a recovery of $116,000 for year ended December 31, 2017, as compared to $337,000 for the year ended December 31, 2016. Net charge-offs related to loans secured by home equity loans decreased $102,000, or 134.2%, to a recovery of $26,000 for year ended December 31, 2017, as compared to $76,000 for the year ended December 31, 2016.  Net charge-offs related to loans secured by construction and land loans decreased $79,000, or 114.5%, to a recovery of $148,000 for year ended December 31, 2017, as compared to a recovery of $38,000 for the year ended December 31, 2016.

Mortgage Banking Activity

In addition to the lending activities previously discussed, we also originate single-family residential mortgage loans for sale in the secondary market through Waterstone Mortgage Corporation.  We originated $2.46 billion in mortgage loans held for sale during the year ended December 31, 2017, which was an increase of $79.4 million, or 3.3%, from the $2.38 billion originated during the year ended December 31, 2016.   The increase in loan production volume was driven by a 12.2% increase in mortgage purchase products partially offset by a 31.6% decrease in refinance products.  The loans sold volume also increased $213.5 million to $2.53 million during the year ended December 31, 2017.  Total mortgage banking income decreased $1.0 million, or 0.8%, to $120.0 million during the year ended December 31, 2017 compared to $121.1 million during the year ended December 31, 2016. The decrease in total mortgage banking income is due in part to a decrease in margin of approximately 3.3% for the year ended December 31, 2017 compared to December 31, 2016. We sell loans on both a servicing-released and a servicing retained basis.  Waterstone Mortgage Corporation has contracted with a third party to service the loans for which we retain servicing.

Our overall margin can be affected by the mix of both loan type (conventional loans versus governmental) and loan purpose (purchase versus refinance).  Conventional loans include loans that conform to Fannie Mae and Freddie Mac standards, whereas governmental loans are those loans guaranteed by the federal government, such as a Federal Housing Authority or U.S. Department of Agriculture loan.  Loans originated for the purchase of a residential property, which generally yield a higher margin than loans originated for refinancing existing loans, comprised 88.8% of total originations during the year ended December 31, 2017, compared to 82.9% of total originations during the year ended December 31, 2016.  The mix of loan type trended slightly towards less conventional loans and more governmental loans comprising 64.5% and 35.5% of all loan originations, respectively, during the year ended December 31, 2017, compared 65.1% and 34.9% of all loan originations, respectively, during the year ended December 31, 2016.  Waterstone Mortgage Corporation originates loans in various states. The states where we originate greater than 10% of total activity are Florida, Minnesota, and Wisconsin.

Investment Activities

Wauwatosa Investments, Inc. is WaterStone Bank's investment subsidiary headquartered in the State of Nevada.  Wauwatosa Investments, Inc. manages the back office function for WaterStone Bank's investment portfolio. Our Chief Financial Officer and Treasury Officer are responsible for executing purchases and sales in accordance with our investment policy and monitoring the investment activities of Wauwatosa Investments, Inc. The investment policy is reviewed annually by management and changes to the policy are recommended to and subject to the approval of our board of directors. Authority to make investments under the approved investment policy guidelines is delegated by the board to designated employees. While general investment strategies are developed and authorized by management, the execution of specific actions rests with the Chief Financial Officer and Treasury Officer who may act jointly in performing security trades. The Chief Financial Officer and Treasury Officer are responsible for ensuring that the guidelines and requirements included in the investment policy are followed and that all securities are considered prudent for investment. The Chief Financial Officer and the Treasury Officer are authorized to execute investment transactions (purchases and sales) without the prior approval of the board provided they are within the scope of the established investment policy.

Our investment policy requires that all securities transactions be conducted in a safe and sound manner. Investment decisions are based upon a thorough analysis of each security instrument to determine its quality, inherent risks, fit within our overall asset/liability management objectives, effect on our risk-based capital measurement and prospects for yield and/or appreciation.

 Consistent with our overall business and asset/liability management strategy, which focuses on sustaining adequate levels of core earnings, our investment portfolio is comprised primarily of securities that are classified as available for sale.  During the year ended December 31, 2017, one municipal security with a total book value of $555,000 was sold at a loss of $107,000.  During the year ended December 31, 2016, no investment securities were sold.  During the year ended December 31, 2015, one municipal security with a total book value of $991,000 was sold at a gain of $44,000.

Available for Sale Portfolio

Government Sponsored Enterprise Bonds.  At December 31, 2017, our Government sponsored enterprise bonds totaled $2.5 million, all of which were issued by Fannie Mae and were classified as available for sale.  The weighted average yield on these securities was 1.18% and the weighted average remaining average life was 0.3 years at December 31, 2017.  While these securities generally provide lower yields than other investments in our securities investment portfolio, we maintain these investments, to the extent appropriate, for liquidity purposes and prepayment protection.  The estimated fair value of our government sponsored enterprise bond portfolio at December 31, 2017 was $3,000 less than the amortized cost of $2.5 million.

Mortgage-backed Securities and Collateralized Mortgage Obligations.  We purchase mortgage-backed securities and collateralized mortgage obligations guaranteed by Fannie Mae, Freddie Mac and Ginnie Mae.  We invest in mortgage-backed securities and collateralized mortgage obligations to achieve positive interest rate spreads with minimal administrative expense, and to lower our credit risk.  We regularly monitor the credit quality of this portfolio.

Mortgage-backed securities and collateralized mortgage obligations are created by the pooling of mortgages and the issuance of a security.  These securities typically represent a participation interest in a pool of single-family or multi-family mortgages, although we focus our investments on mortgage related securities backed by one- to four-family mortgages.  The issuers of such securities pool and resell the participation interests in the form of securities to investors such as WaterStone Bank, and in the case of government agency sponsored issues, guarantee the payment of principal and interest to investors.  Mortgage-backed securities and collateralized mortgage obligations generally yield less than the loans that underlie such securities because of the cost of payment guarantees, if any, and credit enhancements.  These fixed-rate securities are usually more liquid than individual mortgage loans.

At December 31, 2017, mortgage-backed securities totaled $57.4 million. The mortgage-backed securities portfolio had a weighted average yield of 2.49% and a weighted average remaining life of 4.0 years at December 31, 2017. The estimated fair value of our mortgage-backed securities portfolio at December 31, 2017 was $84,000 more than the amortized cost of $57.4 million. Mortgage-backed securities valued at $2.5 million were pledged as collateral for mortgage banking activities as of December 31, 2017. Investments in mortgage-backed securities involve a risk that actual prepayments may differ from estimated prepayments over the life of the security, which may require adjustments to the amortization of any premium or accretion of any discount relating to such instruments, thereby changing the net yield on such securities. There is also reinvestment risk associated with the cash flows from such securities or if such securities are redeemed by the issuer. In addition, the market value of such securities may be adversely affected in a rising interest rate environment, particularly since all of our mortgage-backed securities have a fixed rate of interest. The relatively short weighted average remaining life of our mortgage-backed security portfolio mitigates our potential risk of loss in a rising interest rate environment.

At December 31, 2017, collateralized mortgage obligations totaled $60.5 million. At December 31, 2017, the collateralized mortgage obligations portfolio consisted entirely of securities backed by government sponsored enterprises or U.S. Government agencies.  The collateralized mortgage obligations portfolio had a weighted average yield of 2.24% and a weighted average remaining life of 2.9 years at December 31, 2017. The estimated fair value of our collateralized mortgage obligations portfolio at December 31, 2017 was $813,000 less than the amortized cost of $61.3 million. Investments in collateralized mortgage obligations involve a risk that actual prepayments may differ from estimated prepayments over the life of the security, which may require adjustments to the amortization of any premium or accretion of any discount relating to such instruments, thereby changing the net yield on such securities. There is also reinvestment risk associated with the cash flows from such securities or if such securities are redeemed by the issuer. In addition, the market value of such securities may be adversely affected in a rising interest rate environment, particularly since all of our collateralized mortgage obligations have a fixed rate of interest. The relatively short weighted average remaining life of our collateralized mortgage obligation portfolio mitigates our potential risk of loss in a rising interest rate environment.

Municipal Obligations.  These securities consist of obligations issued by school districts, counties and municipalities or their agencies and include general obligation bonds, industrial development revenue bonds and other revenue bonds.  Our investment policy requires that such municipal obligations be rated A+ or better by a nationally recognized rating agency at the date of purchase.  A security that is downgraded below investment grade will require additional analysis of creditworthiness and a determination will be made to hold or dispose of the investment.  At December 31, 2017, our municipal obligations portfolio totaled $63.8 million, all of which was classified as available for sale.  The weighted average yield on this portfolio was 2.85% at December 31, 2017, with a weighted average remaining life of 5.4 years.  The estimated market value of our municipal obligations bond portfolio at December 31, 2017 was $1.3 million more than the amortized cost of $62.5 million.

As of December 31, 2017, the Company identified one municipal security that was deemed to be other-than-temporarily impaired.  The security was 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 the security in this municipality resulted in $77,000 in credit losses that were charged to earnings with respect to this municipal security. An additional $17,000 credit loss was charged to earnings during the year ended December 31, 2014 with respect to this security as a sale occurred at a discounted price. As of December 31, 2017, the remaining impaired bond had an amortized cost of $116,000 and a total life-to-date impairment of $94,000.  

Other Debt Securities.  As of December 31, 2017, we held other debt securities with a fair value of $14.5 million and amortized cost of $15.0 million.  Other debt securities consist of corporate bonds. The weighted average yield on this portfolio was 3.56% at December 31, 2017, with a weighted average remaining life of 8.8 years.

Certificates of Deposit.  At December 31, 2017, we held certificates of deposit with a fair value and amortized cost of $981,000.  The weighted average yield on these securities was 1.48% and the weighted average remaining average life was 0.5 years at December 31, 2017.  While these certificates generally provide lower yields than other investments in our securities investment portfolio, we maintain these investments, to the extent appropriate, for liquidity purposes and prepayment protection.

The following table sets forth the carrying values of our available for sale securities portfolio at the dates indicated.

The following table sets forth, by issuer, the amortized cost and estimated fair value of our investments in a single issuer, as of December 31, 2017, that exceeded 10% of our stockholders' equity as of that date.

Portfolio Maturities and Yields.  The composition and maturities of the securities portfolio at December 31, 2017 are summarized in the following table.  Maturities are based on the final contractual payment dates and do not reflect the impact of prepayments or early redemptions that may occur.  Municipal obligation yields have not been adjusted to a tax-equivalent basis.  Certain mortgage related securities have interest rates that are adjustable and will reprice annually within the various maturity ranges.  These repricing schedules are not reflected in the table below.
