1.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Consolidation

The unaudited interim Consolidated Financial Statements of HarborOne Bancorp, Inc. (the “Company”) presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by the U.S. generally accepted accounting principles (“GAAP”).  In the opinion of management, all adjustments and disclosures considered necessary for the fair presentation of the accompanying Consolidated Financial Statements have been included.  Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2016 and 2015 and notes thereto included in the Company’s Annual Report on Form 10-K.

The unaudited interim Consolidated Financial Statements include the accounts of the Company, the Company’s subsidiaries Legion Parkway Company LLC, a security corporation formed on July 13, 2016 and HarborOne Bank (the “Bank”); and the Bank’s wholly-owned subsidiaries.  The Bank’s subsidiaries consist of a mortgage company and two security corporations.  Merrimack Mortgage Company, LLC (“Merrimack Mortgage”) was acquired and became a wholly-owned subsidiary of the Bank on July 1, 2015.  The security corporations were established for the purpose of buying, holding and selling securities on their own behalf.  All significant intercompany balances and transactions have been eliminated in consolidation.

Stock Conversion

On June 29, 2016, the Bank reorganized into a two-tier mutual holding company structure with a mid-tier stock holding company. The Company sold 14,454,396 shares of common stock at $10.00 per share, including 1,187,188 shares purchased by the Company’s Employee Stock Ownership Plan (“ESOP”). In addition, the Company issued 17,281,034 shares to HarborOne Mutual Bancshares, a mutual holding company (the “MHC”) and 385,450 shares to The HarborOne Foundation,a charitable foundation formed in connection with the stock offering and dedicated to supporting charitable organizations operating in the Bank’s local community. A total of 32,120,880 shares of common stock were outstanding following the completion of the stock offering. The direct costs of the Company’s stock offering of $3.9 million were deferred and deducted from the proceeds of the offering. 

Upon the completion of the stock offering, a special “liquidation account” was established for the benefit of certain depositors of the Bank in an amount equal to the percentage ownership interest in the equity of the Company held by persons other than the MHC as of the date of the latest balance sheet contained in the prospectus. The Company is not permitted to pay dividends on its capital stock if the Company’s shareholders’ equity would be reduced below the amount of the liquidation account. The liquidation account will be reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases in an eligible account holder’s qualifying deposits will not restore such holder’s interest in the liquidation account.

Nature of Operations

The Company provides a variety of financial services to individuals and businesses through its fourteen full-service and two limited-service bank offices in eastern Massachusetts, a commercial lending office in Providence, Rhode Island, and a loan office in Westford, Massachusetts.  Merrimack Mortgage maintains 33 offices in Massachusetts, New Hampshire, and Maine, and is also licensed to lend in seven additional states. 

The Company’s primary deposit products are checking, money market, savings and term certificate of deposit accounts while its primary lending products are commercial real estate, commercial, residential mortgages and consumer loans, including indirect automobile lending. The Company also originates, sells and services residential mortgage loans primarily through Merrimack Mortgage.

Use of Estimates

In preparing unaudited interim Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuations of mortgage servicing rights, derivatives, goodwill and deferred tax assets. 

Allowance for Loan Losses

The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings.  Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed and generally do not exceed the time frame provided in the FDIC’s Uniform Retail Credit Classification and Account Management Policy.  Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a regular basis by management.  This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.  The allowance consists of general, allocated and unallocated components, as further described below.

General component

The general component of the allowance for loan losses is based on historical loss experience adjusted for qualitative factors stratified by the Company’s loan segments.  Management uses arolling average of historical losses based on a time frame appropriate to capture relevant loss data for each loan segment except commercial real estate and commercial loans.  Due to the lack of historical loss experience for our commercial real estate and commercial loan portfolio, we utilize peer loss data.  Adjustments to this historical loss factor are considered for the following qualitative factors: levels/trends in delinquencies; trends in volume and terms of loans; effects of changes in risk selection and underwriting standards and other changes in lending policies, procedures and practices; experience/ability/depth of lending management and staff; and national and local economic trends and conditions.  There were no changes in the Company’s policies or methodology pertaining to the general component of the allowance for loan losses during 2016 or the nine months ended September 30, 2017.  The qualitative factors are determined based on the various risk characteristics of each loan segment.  Risk characteristics relevant to each portfolio segment are as follows:

Residential real estate – The Company generally does not originate portfolio loans with a loan-to-value ratio greater than 80 percent without obtaining private mortgage insurance and does not generally grant loans that would be classified as subprime upon origination.  The Company generally has first or second liens on property securing equity lines of credit.  Loans in this segment are generally collateralized by residential real estate and repayment is dependent on the credit quality of the individual borrower.  The overall health of the economy, including unemployment rates and housing prices, can have an effect on the credit quality in this segment.  

Commercial real estate – Loans in this segment are primarily secured by income-producing properties in southeastern New England.  The underlying cash flows generated by the properties can be adversely impacted by a downturn in the economy as evidenced by increased vacancy rates, which in turn, could have an effect on the credit quality in this segment.  Management obtains rent rolls annually and continually monitors the cash flows of these loans.

Construction – Loans in this segment include both residential and commercial construction loans.  Residential construction loans include loans to build one- to four-family owner-occupied properties, which are subject to the same credit quality factors as residential real estate loans.  Commercial construction loans may include speculative real estate development loans for which payment is derived from lease or sale of the property.  Credit risk is affected by cost overruns, time to lease or sell at an adequate price, and market conditions.

Commercial – Loans in this segment are made to businesses and are generally secured by assets of the business.  Repayment is expected from the cash flows of the business.  A weakened economy, and resultant decreased consumer or business spending, could have an effect on the credit quality in this segment.  

Consumer – Loans in this segment are generally secured by automobiles or unsecured and repayment is dependent on the credit quality of the individual borrower.

Allocated component

The allocated component relates to loans that are classified as impaired.  Residential real estate, commercial, commercial real estate and construction loans are evaluated for impairment on a loan-by-loan basis.  Impairment is determined by nonaccrual status, whether a loan is subject to a troubled debt restructuring agreement or in the case of certain loans, based on the internal credit rating.  Large groups of smaller balance homogeneous loans are collectively evaluated for impairment.  Accordingly, except for troubled debt restructuring (“TDR”), the Company does not separately identify individual consumer loans for impairment evaluation. 

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement.  Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due.  Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired.  Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. 

The Company periodically may agree to modify the contractual terms of loans.  When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a TDR.  All TDRs are initially classified as impaired.  Impairment is measured by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent.  An allowance is established when the discounted cash flows or collateral value of the impaired loan is lower than the carrying value of that loan.

Unallocated component

The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating allocated and general reserves in the portfolio. The unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. Additionally the Company's unseasoned commercial portfolio and use of peer group data to establish general reserves for the commercial portfolio adds another element of risk to management's estimates.

Stock-based Compensation Plans

The Company’s stock-based compensation plans provide for awards of stock options, restricted stock and other stock-based compensation to directors, officers and employees.  The cost of employee services received in exchange for awards of equity instruments is based on the grant-date fair value of those awards.  Compensation cost is recognized over the requisite service period as a component of compensation expense.  The Company uses the Black-Scholes option-pricing model to determine the fair value of stock options granted, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. The Company has elected to early adopt Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.Under this Update, the Company has elected to account for forfeitures of share-based payments by recognizing forfeitures of awards as they occur (e.g., when an award does not vest because the employee leaves the Company or does not meet specific performance measures).

Earnings Per Share

Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period.  Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. The restricted stock awards are participating securities; therefore unvested awards are included as common shares outstanding in the computation of basic earnings per share. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate to outstanding stock options awards and are determined using the treasury stock method.

Recent Accounting Pronouncements

As an “emerging growth company” as defined in Title 1 of the Jumpstart Our Business Startups (JOBS) Act, the Company has elected to use the extended transition period to delay the adoption of new or reissued accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies.  As of September 30, 2017, there is no significant difference in the comparability of the financial statements as a result of this extended transition period.

In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. This guidance changes the recognition and presentation requirements of hedge accounting, including eliminating the requirement to separately measure and report hedge ineffectiveness and presenting all items that affect earnings in the same income statement line as the hedged item. This guidance also provides new alternatives for applying hedge accounting to additional hedging strategies, measuring the hedged item in fair value hedges of interest rate risk, reducing the complexity of applying hedge accounting by easing the requirements for effectiveness testing, hedge documentation and application of the critical terms match method, and reducing the risk of material error corrections if a company applies the shortcut method inappropriately.  This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company does not have any derivatives within the scope of the ASU.

In March 2017, the FASB issued ASU 2017-08, Receivables- Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The Company elected to early adopt this new accounting guidance effective January 1, 2017 and the adoption did not have a material impact on the Consolidated Financial Statements.

In January 2017, FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.  This update changes the quantitative impairment test to require an entity to perform a one-step test and record the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value, not to exceed the amount of goodwill allocated to the reporting unit.  This new guidance does not amend the optional qualitative assessment of goodwill impairment.  For SEC filers, the ASU is effective for impairment tests in fiscal years beginning after December 15, 2019.  For non-public business entities, the ASU is effective for impairment tests in fiscal years beginning after December 15, 2021.  Early adoption is permitted for impairment tests performed on testing dates after January 1, 2017.  The Company elected to early adopt this new accounting guidance effective October 1, 2017 and the adoption did not have an impact on the Consolidated Financial Statements.

In June 2016, FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), which requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts.  Entities will now use forward-looking information to better form their credit loss estimates.  The ASU also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio.  For public entities that are SEC filers, this ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.  For non-public entities, this ASU is

10

effective for fiscal years beginning after December 15, 2020, and for interim periods within fiscal years beginning after December 15, 2021.  Early application will be permitted for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018.  Management has identified an implementation team that is in the process of developing an understanding of this pronouncement, evaluating the impact of this pronouncement and researching additional software resources that could assist with the implementation.

In February 2016, FASB issued ASU 2016-02,  Leases (Topic 842).  This update requires a lessee to record a right-to-use asset and a liability representing the obligation to make lease payments for long-term leases.  For public business entities, this update is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  For non-public business entities, this update is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years beginning after December 15, 2020.  While we are currently evaluating the impact of the new standard, we expect an increase to the Consolidated Balance Sheets for right-of-use assets and associated lease liabilities but no material impact to the Consolidated Statement of Operations, for arrangements previously accounted for as operating leases.

In January 2016, FASB issued ASU 2016-01, Financial Instruments – Overall, (Subtopic 825-10).  The amendments in this update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments.  Targeted improvements to generally accepted accounting principles include the requirement for equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, the elimination of the requirement for non-public business entities to disclose the fair value of financial instruments measured at amortized cost and the elimination of the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost.  For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years.  For non-public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019.  Management currently does not expect this to have a material impact on the Company's Consolidated Financial Statements as the Company does not currently hold any equity securities.

In May 2014, FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The amendments in this update create Topic 606, Revenue from Contracts with Customers, and supersede the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve the core principle, a company should apply a five step approach to revenue recognition. For public business entities, this ASU is effective for annual reporting periods, including interim periods, beginning after December 15, 2017. For non-public business entities, this ASU is effective for annual reporting periods beginning after December 31, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early application is permitted, but only for annual reporting periods beginning after December 15, 2016. The Bank's primary source of revenue is interest income on financial assets and income from mortgage banking activities, which are explicitly excluded from the scope of the new guidance.  As a result, adoption is not expected to have a material impact on the Company’s Consolidated Financial Statements. However, the Company will continue to monitor developments and additional guidance up to the effective date of these amendments.

Management evaluates securities for other-than-temporary impairment (“OTTI”) at each reporting period, and more frequently when economic or market concerns warrant such evaluation.

At September 30, 2017, twenty-eight debt securities with an amortized cost of $89.6 million have unrealized losses with aggregate depreciation of 0.90% from the Company’s amortized cost basis. 

The unrealized losses on the Company’s securities were primarily caused by changes in interest rates.  All of these investments are guaranteed by government and government-sponsored enterprises.  Accordingly, it is expected that the securities would not be settled at a price less than the par value of the investment.  Because the decline in fair value is attributable to changes in interest rates and not to credit quality, and because the Company does not intend to sell the investments and it is more likely than not that the Company will not be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider these investments to be OTTI at September 30, 2017.

During the nine months ended September 30, 2017, the Company sold indirect auto loans of $5.0 million. The loans were classified as loans held for sale at March 31, 2017 and a gain of $78,000 was recorded in the first quarter.  During the nine months ended September 30, 2016, the Company sold $10.0 million of indirect loans and recognized gains of $79,000.  No indirect auto loans were sold during the three months ended September 30, 2017 and 2016.  The unpaid principal balance of indirect auto loans serviced for others was $25.5 million and $31.4 million at September 30, 2017 and December 31, 2016, respectively. 

The Company did not sell residential portfolio loans during the three or nine months ended September 30, 2017. The Company sold residential portfolio loans of $29.5 million during the nine months ended September 30, 2016.  Included in mortgage banking income for the nine months ended September 30, 2016is the related gain on sale of $501,000.  No residential loans were sold from the portfolio during the three months ended September 30, 2016.

The Company has transferred a portion of its originated commercial real estate loans to participating lenders.  The amounts transferred have been accounted for as sales and are therefore not included in the Company’s accompanying unaudited interim Consolidated Balance Sheets.  The Company and participating lenders share ratably in cash flows and any gains or losses that may result from a borrower’s lack of compliance with contractual terms of the loan.  The Company continues to service the loans on behalf of the participating lenders and, as such, collects cash payments from the borrowers, remits payments to participating lenders and disburses required escrow funds to relevant parties.  At September 30, 2017 and December 31, 2016, the Company was servicing loans for participants aggregating $62.1 million and $45.3 million, respectively.

Interest income recognized and interest income recognized on a cash basis in the table above represents interest income for the three and nine months ended September 30, 2017 and 2016, not for the time period designated as impaired.  As part of a workout agreement, the Company is committed to advance $165,000 in additional funds on one commercial impaired loan.

The following table sets forth TDRs during the three and nine months ended September 30, 2017 and 2016:

HarborOne Bancorp, Inc.

Notes to Consolidated Financial Statements (unaudited)

The recorded investment in TDRs was $29.7 million and $31.8 million at September 30, 2017 and 2016, respectively.  Of these loans, $8.1 million and $6.8 million were on non-accrual at September 30, 2017 and 2016, respectively.

All TDR loans are considered impaired and management performs a discounted cash flow calculation to determine the amount of impairment reserve required on each loan.  TDR loans which subsequently default are reviewed to determine if the loan should be deemed collateral dependent.  In either case, any reserve required is recorded as part of the allowance for loan losses.

During the three and nine months ended September 30, 2017, there were no payment defaults on TDRs.  During the nine months ended September 30, 2016, one troubled debt restructuring with a recorded investment of $107,000 defaulted.  During the three months ended September 30, 2016, there were no payment defaults on TDRs.

Credit Quality Information

The Company uses a ten grade internal loan rating system for commercial real estate, commercial construction and commercial loans, as follows:

Loans rated 1 – 6 are considered “pass” rated loans with low to average risk.

Loans rated 7 are considered “special mention.”  These loans are starting to show signs of potential weakness and are being closely monitored by management. 

Loans rated 8 are considered “substandard.”  Generally, a loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged.  There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected.

Loans rated 9 are considered “doubtful.”  Loans classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable.

Loans rated 10 are considered “uncollectible” (loss), and of such little value that their continuance as loans is not warranted. 

Loans not rated consist primarily of residential construction loans and certain smaller balance commercial real estate and commercial loans that are managed by exception. 

On an annual basis, or more often if needed, the Company formally reviews on a risk adjusted basis, the ratings on all commercial real estate, construction and commercial loans.  Semi-annually, the Company engages an independent third party to review a significant portion of loans within these segments.  Management uses the results of these reviews as part of its annual review process. 

On a monthly basis, the Company reviews the residential construction, residential real estate and consumer installment portfolios for credit quality primarily through the use of delinquency reports.

4.MORTGAGE LOAN SERVICING

The Company sells residential mortgages to government-sponsored entities and other parties.  The Company retains no beneficial interests in these loans, but may retain the servicing rights of the loans sold.  Mortgage loans serviced for others are not included in the accompanying unaudited interim Consolidated Balance Sheets.  The risks inherent in mortgage servicing rights (“MSRs”) relate primarily to changes in prepayments that primarily result from shifts in mortgage interest rates.  The unpaid principal balances of mortgage loans serviced for others were $1.92 billion and $1.85 billion as of September 30, 2017 and December 31, 2016, respectively. 

The Company accounts for MSRs at fair value.  The Company obtains valuations from independent third parties to determine the fair value of MSRs.  Key assumptions used in the estimation of fair value include prepayment speeds, discount rates, default rates, cost to service, and contractual servicing fees.  At September 30, 2017 and December 31, 2016, the following weighted average assumptions were used in the calculation of fair value of MSRs:

	September 30,		December 31,
	2017		2016
Prepayment speed	10.29	%	9.49	%
Discount rate	9.26		9.25
Default rate	2.02		1.71

The following summarizes changes to mortgage servicing rights for the nine months ended September 30, 2017 and 2016:

	Nine Months Ended September 30,
	2017		2016
	(in thousands)
Balance, beginning of period	$	20,333	$	12,958
Additions from loans sold with servicing retained		2,025		6,676
Changes in fair value due to :
Reductions from loans paid off during the period		(1,138)		(1,229)
Changes in valuation inputs or assumptions		(844)		(2,871)
Balance, end of period	$	20,376	$	15,534

For the three months ended September 30, 2017 and 2016, contractually specified servicing fees included in other mortgage banking income amounted to $1.3 million and $1.1 million, respectively.  For the nine months ended September 30, 2017 and 2016, contractually specified servicing fees included in other mortgage banking income amounted to $3.9 million and $2.9 million, respectively.

6.BORROWED FUNDS

Borrowed funds at September 30, 2017 and December 31, 2016 consist of FHLB advances.  Short-term advances were $10.0 million and $80.0 million with weighted average rates of 1.33% and 0.77% at September 30, 2017 and December 31, 2016, respectively. Long-term advances are summarized by maturity date below.  There were no callable advances at September 30, 2017 or December 31, 2016.

	$	266,366	1.86	%	$	195,119	2.24	%
* Includes an amortizing advance requiring monthly principal and interest payments of $1,000.

The FHLB advances are secured by a blanket security agreement on qualified collateral defined primarily as 75% of the carrying value of first mortgage loans on residential property and 94% of the fair value of government-sponsored enterprise and mortgage-backed securities obligations. 

The Company also has an available line of credit with the Federal Reserve Bank of Boston secured by 74% of the carrying value of indirect auto loans with principal balance amounting to $156.0 million and $207.9 million, respectively, of which no amount was outstanding at September 30, 2017 and December 31, 2016, respectively.

7.INCOME TAXES

For the three and nine months ended September 30, 2017, the Company recorded an expense of $1.7 million and $5.1 million, respectively, representing an effective tax rate of 37.4% and 36.9%, respectively.  For the three and nine months ended September 30, 2016, the Company recorded an expense of $1.9 million and $1.2 million, respectively, representing an effective tax rate of 34.8% and 28.8%, respectively.  The increase in the effective tax rate in 2017 is due primarily to the increase in nondeductible expense related to the ESOP and decreased tax-advantaged income.

8.OTHER COMMITMENTS AND CONTINGENCIES

Loan Commitments

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers.  These financial instruments include commitments to extend credit and advance funds on various lines of credit.  Those commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the accompanying unaudited interim Consolidated Financial Statements.

23

HarborOne Bancorp, Inc.

Notes to Consolidated Financial Statements (unaudited)

The Company’s exposure to credit loss is represented by the contractual amount of these commitments.  The Company uses the same credit policies in making commitments as it does for on-balance sheet instruments.

The following off-balance sheet financial instruments were outstanding at September 30, 2017 and December 31, 2016.  The contract amounts represent credit risk.

	September 30,		December 31,
	2017		2016
	(in thousands)
Commitments to grant loans	$	99,062	$	75,914
Unadvanced funds on home equity lines of credit		79,410		82,797
Unadvanced funds on revolving lines of credit		65,676		58,238
Unadvanced funds on construction loans		116,766		49,999

Commitments to extend credit and unadvanced portion of construction loans are agreements to lend to a customer, as long as there is no violation of any condition established in the contract.  Commitments to grant loans generally have fixed expiration dates or other termination clauses and may require payment of a fee.  The commitments for unadvanced funds on construction loans, home equity and revolving lines of credit may expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements.  The Company evaluates each customer’s credit worthiness on a case-by-case basis.  Commitments to grant loans, and unadvanced construction loans and home equity lines of credit are collateralized by real estate, while revolving lines of credit are unsecured.

Other Commitments

On May 31, 2017, the Bank entered into a ground lease for property located in Stoughton, Massachusetts, to develop as a prospective branch site.  Until January 31, 2018, the Bank has the right to terminate the lease without any future obligations.

9.DERIVATIVES

The Company is party to a variety of derivative transactions, including derivative loan commitments, forward loan sale commitments and interest rate swap contracts. The Company enters into derivative contracts in order to meet the financing needs of its customers. The Company also enters into derivative contracts as a means of reducing its interest rate risk and market risk. 

All derivatives are recognized in the unaudited interim Consolidated Balance Sheets at fair value.  Changes in the fair value of derivatives are recognized in earnings.  The Company did not have any fair value hedges or cash flow hedges at September 30, 2017 and December 31, 2016. 

Derivative Loan Commitments

Mortgage loan commitments qualify as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding.  The Company enters into commitments to fund residential mortgage loans at specified times in the future, with the intention that these loans will subsequently be sold in the secondary market.  A mortgage loan commitment binds the Company to lend funds to a potential borrower at a specified interest rate and within a specified period of time, generally up to 60 days after inception of the rate lock.

Outstanding derivative loan commitments expose the Company to the risk that the price of the loans arising from exercise of the loan commitment might decline from inception of a rate lock to funding of the loan due to increases in mortgage interest rates.  If interest rates increase, the value of these loan commitments decreases.  Conversely, if interest rates decrease, the value of these loan commitments increases. 

24

HarborOne Bancorp, Inc.

Notes to Consolidated Financial Statements (unaudited)

Forward Loan Sale Commitments

The Company utilizes both “mandatory delivery” and “best efforts” forward loan sale commitments to mitigate the risk of potential decreases in the values of loans that would result from the exercise of the derivative loan commitments. 

With a “mandatory delivery” contract, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date.  If the Company fails to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, it is obligated to pay a “pair-off” fee, based on then-current market prices, to the investor to compensate the investor for the shortfall.

With a “best efforts” contract, the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes.  Generally, the price the investor will pay the seller for an individual loan is specified prior to the loan being funded (e.g., on the same day the lender commits to lend funds to a potential borrower).

The Company expects that these forward loan sale commitments will experience changes in fair value opposite to the change in fair value of derivative loan commitments. 

Interest Rate Swaps

The Company enters into interest rate swap agreements that are transacted to meet the financing needs of its commercial customers. Offsetting interest rate swap agreements are simultaneously transacted with a third-party financial institution to effectively eliminate the Company’s interest rate risk associated with the customer swaps. The primary risks associated with these transactions arise from exposure to the ability of the counterparties to meet the terms of the contract.  Mortgage-backed securities with a fair value of $5.9 million are pledged to secure the Company’s liability for the offsetting interest rate swaps (see Note 2).  The interest rate swap notional amount below is the aggregate notional amount of the customer swap and the offsetting third-party swap.

Risk Participation Agreements

The Company has entered into risk participation agreements with the correspondent institutions and shares in any interest rate swap losses incurred as a result of the commercial loan customers’ termination of a loan level interest rate swap agreement prior to maturity. The Company records these risk participation agreements at fair value. The Company’s maximum credit exposure is based on its proportionate share of the settlement amount of the referenced interest rate swap. Settlement amounts are generally calculated based on the fair value of the swap plus outstanding accrued interest receivables from the customer.

10.COMPENSATION AND BENEFIT PLANS

Directors’ Retirement Plan

The Company has elected to freeze the Directors’ Retirement Plan effective December 31, 2017.  The balance of the liability at September 30, 2017 was $1.6 million.

Supplemental Retirement Plans

On March 1, 2016, in anticipation of the reorganization, the Company amended a supplemental executive retirement Plan with an executive to accelerate vesting.  This amendment increased the net present value of the benefit obligation in the amount of $891,000 and this increase was expensed in the first quarter of 2016. 

Employee Stock Ownership Plan

On June 29, 2016, the Company established an ESOP to provide eligible employees the opportunity to own Company stock. The plan is a tax-qualified retirement plan for the benefit of the Company employees.  The ESOP shares were purchased through a loan from the Company and as the debt is repaid, shares are released.  Contributions are allocated to eligible participants on the basis of compensation, subject to federal tax limits.  The unreleased shares are deducted from stockholders’ equity as unearned ESOP shares in the accompanying balance sheets.  The number of shares committed to be released per year is 59,359 through 2035.

11.STOCK-BASED COMPENSATION

Under the HarborOne Bancorp, Inc. 2017 Stock Option and Incentive Plan (the “Equity Plan”), adopted on August 9, 2017, the Company may grant options, stock appreciation rights, restricted stock, restricted units, unrestricted stock awards, cash based awards, performance share awards, and dividend equivalent rights to its directors, officers and employees. Total shares reserved for issuance under the plan are 2,077,577. Both incentive stock options and non-qualified stock options may be granted under the Equity Plan, with the total shares reserved for options equaling 1,483,984. The exercise price of each option equals the market price of the Company’s stock on the date of grant and the maximum term of each option is ten years. The total number of shares reserved for restricted stock or restricted units is 593,593. Options and awards vest ratably over three years. The fair value of shares awarded is based on the market price at the date of grant.

Expense related to options and restricted stock granted to directors is recognized as directors' fees within noninterest expense.

The Company has standard form agreements used for stock option and restricted stock awards. The standard form agreements used for the Chief Executive Officer and all other executive officers have previously been disclosed in Securities and Exchange Commission filings and generally provide that: (1) any unvested options or unvested restricted stock vest upon a Change in Control; and, that (2) any stock options which vest pursuant to a Change in Control, which is an event described in Section 280G of the Internal Revenue Code of 1986, will be cashed out at the difference between the acquisition price and the exercise price of the stock option.

Stock Options

The fair value of each option grant is estimated on the date of the grant using the Black-Scholes option-pricing model with the following assumptions:

· Volatility is based on peer group volatility due to lack of sufficient trading history for the Company.

27

HarborOne Bancorp, Inc.

Notes to Consolidated Financial Statements (unaudited)

· Expected life represents the period of time that the option is expected to be outstanding, taking into account the contractual term and the vesting period.

12.MINIMUM REGULATORY CAPITAL REQUIREMENTS

The Company and Bank are subject to various regulatory capital requirements administered by the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation (the “FDIC”).  Failure to meet minimum capital requirements can result in mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s Consolidated Financial Statements.

Under the capital rules, risk-based capital ratios are calculated by dividing Tier 1 and total risk-based capital, respectively, by risk-weighted assets.  Assets and off-balance sheet credit equivalents are assigned to one of several risk-weight categories, based primarily on relative risk.  The rules require banks and bank holding companies to maintain a minimum common equity Tier 1 capital ratio of 4.5%, a minimum Tier 1 capital ratio of 6.0%, a total capital ratio of 8.0% and a leverage ratio of 4.0%.  Additionally, subject to a transition schedule, the capital rules require a bank holding company to establish a capital conservation buffer of common equity Tier 1 capital in an amount above the minimum risk-based capital requirements equal to 2.5% of total risk weighted assets, or face restrictions on the ability to pay dividends, pay discretionary bonuses, and to engage in share repurchases.

Under the FDIC’s prompt corrective action rules, which became effective January 1, 2015, an insured state nonmember bank is considered “well capitalized” if its capital ratios meet or exceed the ratios as set forth in the following table and is not subject to any written agreement, order, capital directive, or prompt corrective action directive to meet and maintain a specific capital level for any capital measure.  The Bank must meet well capitalized requirements under prompt corrective action provisions.  Prompt corrective action provisions are not applicable to bank holding companies.

A bank holding company is considered “well capitalized” if the bank holding company (i) has a total risk-based capital ratio of at least 10.0%, (ii) has a Tier 1 risk-based capital ratio of at least 6.0%, and (iii) is not subject to any written agreement order, capital directive or prompt corrective action directive to meet and maintain a specific capital level for any capital measure.

At September 30, 2017, the capital levels of both the Company and the Bank exceeded all regulatory capital requirements and their regulatory capital ratios were above the minimum levels required to be considered well capitalized for regulatory purposes.  The capital levels of both the Company and the Bank at September 30, 2017 also exceeded the minimum capital requirements including the currently applicable capital conservation buffer of 1.25%.

13.COMPREHENSIVE INCOME (LOSS)

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income.  Although certain changes in assets and liabilities are reported as a separate component of the stockholders’ equity section of the Consolidated Balance Sheets, such items, along with net income, are components of comprehensive income (loss).

The components of accumulated other comprehensive loss, included in stockholders’ equity, are as follows:

14.FAIR VALUE OF ASSETS AND LIABILITIES

Determination of Fair Value

The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures.  The fair value of an asset or liability is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  Fair value is best determined based upon quoted market prices.  However, in many instances, there are no quoted market prices for the Company’s various assets or liabilities.  In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques.  Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.  Accordingly, the fair value estimates may not be realized in an immediate settlement of the asset or liability. 

32

HarborOne Bancorp, Inc.

Notes to Consolidated Financial Statements (unaudited)

The following methods and assumptions were used by the Company in estimating fair value disclosures:

Cash and cash equivalents - The carrying amounts of cash and short-term instruments approximate fair values based on the short-term nature of the assets.

Securities - All fair value measurements are obtained from a third-party pricing service and are not adjusted by management.  Securities measured at fair value in Level 1 are based on quoted market prices in an active exchange market.  Securities measured at fair value in Level 2 are based on pricing models that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes, credit spreads and new issue data. 

FHLB stock - The fair value of Federal Home Loan Bank stock is equal to cost based on redemption provisions.

Loans held for sale - Fair values are based on prevailing market prices for similar commitments.  At September 30, 2017 and December 31, 2016, there were no loans held for sale that were greater than ninety days past due. 

The following table provides the fair value and contractual principal balance outstanding of loans held for sale accounted for under the fair value option:

	September 30,		December 31,
	2017		2016
	(in thousands)
Loans held for sale, fair value	$	96,201	$	86,443
Loans held for sale, contractual principal outstanding		92,981		85,024
Fair value less unpaid principal	$	3,220	$	1,419

Loans - Fair values for mortgage loans and other loans are estimated using discounted cash flow analyses, using market interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.  Fair values for non-performing loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable.

Retirement plan annuities - The carrying value of the annuities are based on their contract values which approximate fair value.

Mortgage servicing rights - Fair value is based on a third party valuation model that calculates the present value of estimated future net servicing income and includes observable market data such as prepayment speeds and default and loss rates.

Deposits and mortgagors’ escrow accounts - The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and certain types of money market accounts) and mortgagors’ escrow accounts are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts).  Fair values for certificates of deposit are estimated using a discounted cash flow calculation that applies market interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Borrowed funds - The fair values of borrowed funds are estimated using discounted cash flow analyses based on the current incremental borrowing rates in the market for similar types of borrowing arrangements.

Accrued interest - The carrying amounts of accrued interest approximate fair value.

Forward loan sale commitments and derivative loan commitments - Forward loan sale commitments and derivative loan commitments are based on fair values of the underlying mortgage loans and the probability of such commitments being exercised.  The assumptions for pull-through rates are derived from internal data and adjusted using management judgment. Derivative loan commitments include the value of servicing rights and non-refundable costs of originating the

loan based on the Company’s internal cost analysis that is not observable.   At September 30, 2017 and December 31, 2016, the weighted average pull-through rate for derivative loan commitments was 87% and 86%, respectively.  

Interest rate swaps and risk participation agreements - The Company’s interest rate swaps are traded in over-the-counter markets where quoted market prices are not readily available.  For these interest rate derivatives, fair value is determined by a third party utilizing models that use primarily market observable inputs, such as swap rates and yield curves.  The pricing models used to value interest rate swaps calculate the sum of each instrument’s fixed and variable cash flows, which are then discounted using an appropriate yield curve to arrive at the fair value of each swap.  The pricing models do not contain a high level of subjectivity as the methodologies used do not require significant judgment.  The Company incorporates credit valuation analysis for counterparty nonperformance risk in the fair value measurement, including the impact of netting applicable credit enhancements such as available collateral.

Off-balance sheet credit-related instruments - Fair values for off-balance sheet, credit related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing.  The fair value of off-balance sheet instruments are immaterial.

Fair Value Hierarchy

The Company groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value.

Level 1 – Valuation is based on quoted prices in active markets for identical assets or liabilities.  Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.

Level 2 – Valuation is based on observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. 

Level 3 – Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.  Level 3 assets and liabilities include assets and liabilities whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as assets and liabilities for which the determination of fair value requires significant management judgment or estimation. 

Transfers between levels are recognized at the end of the reporting period, if applicable.  There were no transfers during the periods presented.

Assets Measured at Fair Value on a Non-recurring Basis

The Company may also be required, from time to time, to measure certain other financial assets on a nonrecurring basis in accordance with generally accepted accounting principles.  These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets.  There were no liabilities measured at fair value on a non-recurring basis at September 30, 2017 and December 31, 2016.  The following table summarizes the fair value hierarchy used to determine each adjustment and the carrying value of the related individual assets.

Notes to Consolidated Financial Statements (unaudited)

Losses applicable to write-downs of impaired loans and other real estate owned and repossessed assets are based on the appraised value of the underlying collateral less estimated costs to sell.  The losses on impaired loans are not recorded directly as an adjustment to current earnings, but rather as a component in determining the allowance for loan losses.  The losses on other real estate owned and repossessed assets represent adjustments in valuation recorded during the time period indicated and not for losses incurred on sales.  Appraised values are typically based on a blend of (a) an income approach using observable cash flows to measure fair value, and (b) a market approach using observable market comparables.  These appraised values may be discounted based on management’s historical knowledge, expertise or changes in market conditions from time of valuation.

15.EARNINGS PER SHARE (“EPS”)

Basic EPS represents net income attributable to common shareholders divided by the weighted-average number of common shares outstanding during the period.  Unvested restricted shares are participating securities and included in the computation of basic earnings per share.  Diluted EPS is computed by dividing net income attributable to common shareholders by the weighted-average number of common shares outstanding, plus the effect of potential dilutive common stock equivalents outstanding during the period.  Unallocated ESOP shares are not deemed outstanding for EPS calculations.

16.SEGMENT REPORTING

The Company has two reportable segments: HarborOne Bank and Merrimack Mortgage.  Revenue from HarborOne Bank consists primarily of interest earned on loans and investment securities and service charges on deposit accounts.  Revenue from Merrimack Mortgage comprises interest earned on loans and fees received as a result of the residential mortgage origination, sale and servicing process. 

The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies.  Segment profit and loss is measured by net income on a legal entity basis.  Intercompany transactions are eliminated in consolidation.

Information about the reportable segments and reconciliation to the unaudited interim Consolidated Financial Statements at September 30, 2017 and 2016 and for the three and nine months then ended is presented in the tables below.  Merrimack Mortgage was acquired in July 2015.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This section is intended to assist in the understanding of the financial performance of the Company and its subsidiaries through a discussion of our financial condition at September  30, 2017, and our results of operations for the three and nine months ended September  30, 2017 and 2016. This section should be read in conjunction with the unaudited interim Consolidated Financial Statements and Notes thereto of the Company appearing in Part I, Item 1 of this Form 10-Q.

Forward-Looking Statements

Certain statements contained in this Quarterly Report on Form 10-Q that are not historical facts may be considered forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These statements, which are based on certain current assumptions and describe our future plans, strategies and expectations, can generally be identified by the use of the words “may,” “will,” “should,” “could,” “would,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” “target” and similar expressions. These statements include, among others, statements regarding our strategy, goals and expectations; evaluations of future interest rate trends and liquidity; expectations as to growth in assets, deposits and results of operations, future operations, market position and financial position; and prospects, plans and objectives of management. You should not place undue reliance on our forward-looking statements. You should exercise caution in interpreting and relying on forward-looking statements because they are subject to significant risks, uncertainties and other factors which are, in some cases, beyond our control.

Forward-looking statements are based on the current assumptions and beliefs of management and are only expectations of future results. The Company’s actual results could differ materially from those projected in the forward-looking statements as a result of, among others, factors referenced under the section captioned “Risk Factors” at Part II, Item 1A of this Form 10-Q, and in our Annual Report on Form 10-K for the year ended December 31, 2016, as updated by the Company’s quarterly reports on Form 10-Q, including this report, and other filings with the Securities and Exchange Commission, adverse conditions in the capital and debt markets and the impact of such conditions on our business activities; changes in interest rates; competitive pressures from other financial institutions; the effects of general economic conditions on a national basis or in the local markets in which we operate, including changes that adversely affect borrowers’ ability to service and repay our loans; changes in the value of securities in our investment portfolio; changes in loan default and charge-off rates; fluctuations in real estate values; the adequacy of loan loss reserves; decreases in deposit levels necessitating increased borrowing to fund loans and investments;operational risks including, but not limited to, cybersecurity, fraud and natural disasters; changes in government regulation; changes in accounting standards and practices; the risk that goodwill and intangibles recorded in our financial statements will become impaired; demand for loans in our market area; our ability to attract and maintain deposits; risks related to the implementation of acquisitions, dispositions, and restructurings; the risk that we may not be successful in the implementation of our business strategy; and changes in assumptions used in making such forward-looking statements. Forward-looking statements speak only as of the date on which they are made. The Company does not undertake any obligation to update any forward-looking statement to reflect circumstances or events that occur after the date the forward-looking statements are made.

Critical Accounting Policies

Certain of our accounting policies, which are important to the portrayal of our financial condition, require management to make difficult, complex or subjective judgments, some of which may relate to matters that are inherently uncertain.  Estimates associated with these policies are susceptible to material changes as a result of changes in facts and circumstances.  Facts and circumstances which could affect these judgments include, but are not limited to, changes in interest rates, changes in the performance of the economy and changes in the financial condition of borrowers.

Management’s Discussion and Analysis

There have been no material changes to our critical accounting policies as compared to the critical accounting policies described in the Company’s Annual Report on Form 10-K.

Comparison of Financial Condition at September 30, 2017 and December 31, 2016

Total Assets.    Total assets increased $211.1 million, or 8.62%, to $2.66 billion at September 30, 2017 from $2.45 billion at December 31, 2016 primarily due to the continued execution of our commercial loan growth strategy. 

Cash and Cash Equivalents.    Cash and cash equivalents increased $44.6 million to $94.8 million at September 30, 2017 from $50.2 million at December 31, 2016. The increase was primarily due to HarborOne Bancorp, Inc.’s participation in the Bank’s reciprocal deposit program that was established in June of 2017. Through the program, the Company’s $68.5 million deposit at the Bank was converted to multiple deposits at other financial institutions which are not eliminated in consolidation.

Loans Held for Sale.    Loans held for sale at September 30, 2017 were $96.2 million, an increase of $9.8 million from $86.4 million at December 31, 2016 due to the seasonal increase in residential mortgage originations. Of the loans held for sale at September 30, 2017, $92.3 million were originated by Merrimack Mortgage and $3.9 million were originated by the Bank.

Loans, net.    At September 30, 2017, net loans were $2.1 billion, an increase of $122.8 million, or 6.20%, from $1.98 billion at December 31, 2016, primarily due to an increase in the Bank’s commercial real estate, construction and commercial loan originations, partially offset by a decrease in consumer loans. Total commercial real estate and commercial loans at September 30, 2017 were $734.7 million, an increase of $138.4 million, or 23.21%, from $596.3 million at December 31, 2016, reflecting the execution of our business strategy to increase commercial lending. Construction loans increased $18.2 million, or 31.18%, in the same period, primarily due to commercial construction loan advances and originations. Consumer loans decreased $29.4 million, or 5.22%, partially the result of a $5.0 million indirect auto loan sale. Our residential portfolio decreased by $1.5 million, or 0.20%. The allowance for loan losses was $17.9 million at September 30, 2017 and $17.0 million December 31, 2016.

The following table provides the composition of our loan portfolio at the dates indicated:

Securities.    Total investment securities at September 30, 2017 were $213.9 million, an increase of $29.5 million, or 16.02%, from December 31, 2016. There were no sales of securities in the third quarter of 2017.  Proceeds from calls of securities amounted to $400,000 in the nine months ended September 30, 2017.  The following table provides the composition of our securities available for sale and held to maturity at the dates indicated:

Mortgage servicing rights.    Mortgage servicing rights are created as a result of our mortgage banking origination activities and accounted for at fair value. At September 30, 2017, we serviced mortgage loans for others with an aggregate outstanding principal balance of $1.92 billion. Total mortgage servicing rights were $20.4 million at September 30, 2017 and December 31, 2016. 

The following table represents the activity for mortgage servicing rights and the related fair value changes during the periods noted:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2017		2016		2017		2016
	(in thousands)
Balance, beginning of period	$	20,313	$	12,688	$	20,333	$	12,958

Changes in fair value due to :
Reductions from loans paid off during the period		(415)		(563)		(1,138)		(1,229)
Changes in valuation inputs or assumptions		(73)		914		(844)		(2,871)
Balance, end of period	$	20,376	$	15,534	$	20,376	$	15,534

The fair value of our mortgage servicing rights is determined by a third party provider that determines the appropriate prepayment speed, discount and default rate assumptions based on our portfolio. Any measurement of fair value is limited by the conditions existing and assumptions made at a particular point in time. Those assumptions may not be appropriate if they are applied to a different point in time. The following table presents weighted average assumptions utilized in determining the fair value of mortgage servicing rights at September 30, 2017 and December 31, 2016:

	September 30,		December 31,
	2017		2016
Prepayment speed	10.29	%	9.49	%
Discount rate	9.26		9.25
Default rate	2.02		1.71

HarborOne Bancorp, Inc.

Management’s Discussion and Analysis

Prepayment speeds are significantly impacted by mortgage rates. Decreasing mortgage rates normally encourage increased mortgage refinancing activity, which reduces the life of the loans underlying the mortgage servicing rights, thereby reducing the value of mortgage servicing rights.

Management has made the strategic decision not to hedge mortgage servicing assets at this point. Therefore, any future declines in interest rates would likely cause further decreases in the fair value of the mortgage servicing rights, and a corresponding detriment to earnings, whereas increases in interest rates would result in increases in fair value, and a corresponding benefit to earnings. Management may choose to hedge the mortgage servicing assets in the future or limit the balance of mortgage servicing rights by selling them or selling loans with the servicing released.

Deposits.    Deposits increased $198.8 million, or 11.01%, to $2.00 billion at September 30, 2017 from $1.80 billion at December 31, 2016. The growth in deposits was driven by an increase of $29.9 million in checking account deposits, $87.5 million in savings account deposits, $71.4 million in money market deposits and $19.1 million in brokered deposits partially offset by a decline in certificates of deposit of $9.1 million.  Included in deposits are $192.6 million in reciprocal deposit relationships, $102.3 million in money markets, $80.3 million in savings deposits, including the Company’s $68.5 million deposit, and $10.0 million in certificates of deposit. The reciprocal deposit program was established in June 2017 and provides access to FDIC insured deposit products in aggregate amounts exceeding the current insurance limits for depositors. Retail growth provided the checking account increase, $41.5 million of the money market increase and $7.1 million of the savings account increase. The decrease in certificates of deposits was due to a $19.6 million decrease in institutional deposits partially offset by the $10.0 million increase in reciprocal accounts. The overall municipal balances increased $42.9 million from December 31, 2016, $29.9 million in money market accounts, $11.9 million in savings accounts and $1.1 million in certificates of deposits. 

Borrowings.   Total borrowings from the FHLB decreased $1.3 million, or 0.45%, to $276.4 million at September 30, 2017 from $275.1 million at December 31, 2016.

Stockholders’ equity.Total stockholders’ equity was $340.6 million at September30, 2017 compared to $329.4 million at December 31, 2016, an increase of 3.41%. The increase from December 31, 2016 is primarily due to net income, share-based compensation and allocated ESOP shares.

Comparison of Results of Operations for the Three and Nine Months Ended September 30, 2017 and 2016

Overview.   Consolidated net income for the three and nine months ended September 30, 2017 was $2.8 million and $8.8 million, respectively, compared to net income of $3.6 million and $3.0 million for the three and nine months ended September 30, 2016. The 2016 results include a one-time, pre-tax contribution of $4.8 million to establish the Foundation. Excluding the contribution expense, net income would have been $5.9 million for the nine months ended September 30, 2016.

Average Balances and Yields. The following tables set forth average balance sheets, annualized average yields and costs, and certain other information for the periods indicated, on a consolidated basis. Interest income on tax-exempt securities and loans has been adjusted to a fully taxable-equivalent (FTE) basis using a federal tax rate of 35%.  All average balances are daily average balances. Non-accrual loans were included in the computation of average balances, but have been reflected in the table as loans carrying a zero yield. The yields set forth below include the effect of deferred fees, discounts and premiums that are amortized or accreted to interest income or expense.

Rate/Volume Analysis. The following table presents, on a tax equivalent basis, the effects of changing rates and volumes on our net interest income for the periods indicated, on a consolidated basis. The rate column shows the effects attributable to changes in rate (changes in rate multiplied by prior volume). The volume column shows the effects attributable to changes in volume (changes in volume multiplied by prior rate). The total column represents the sum of the prior columns. For purposes of this table, changes attributable to both rate and volume, which cannot be segregated, have been allocated proportionately based on the changes due to rate and the changes due to volume.

Interest and Dividend Income.    Interest and dividend income increased $4.3 million, or 22.19%, to $23.4 million for the three months ended September 30, 2017, compared to $19.2 million for the three months ended September 30, 2016. The increase was primarily due to a $3.8 million, or 20.97%, increase in interest on loans and loans held for sale to $21.8 million for the three months ended September 30, 2017 from $18.0 million for the three months ended September 30, 2016. Included in interest on loans and loans held for sale was a $680,000 commercial loan prepayment penalty, while there were no such penalties collected in the prior year quarter. Additionally, the increase in loan interest income was attributable to a 10.44% increase in average loans outstanding as well as the shift in mix to higher

Management’s Discussion and Analysis

yielding commercial loans. The average yield on loans and loans held for sale increased 34 basis points, excluding the prepayment penalty there would have been a 17 basis point increase in the average quarterly yield. Interest and dividend income on securities increased by $346,000, or 35.02%, from $988,000 for the three months ended September 30, 2016 to $1.3 million for the three months ended September 30, 2017.

Compared to the first nine months of 2016, interest and dividend income increased $11.8 million, or 21.51% reflecting similar trends in the quarter over quarter results. Average loans and loans held for sale increased $254.5 million, or 13.47% coupled with a 25 basis point increase in yield resulting in a $10.7 million increase in interest on loans and loans held for sale. Excluding the prepayment penalty there would have been a 20 basis point increase in the average yield.

Interest Expense.    Interest expense increased $885,000, or 27.15%, to $4.1 million for the three months ended September 30, 2017 from $3.3 million for the three months ended September 30, 2016. The increase resulted from a $720,000 increase in interest expense on deposits and a $165,000 increase in interest expense on borrowings. The increase in interest expense on deposits resulted from a 15.68% increase in average balances and a 9 basis point increase in the cost of deposits. Components of the increase included $83.0 million in average brokered deposits at a cost of 1.17% in the third quarter of 2017 whereas average brokered deposit were $549,000 at a cost of 2.17% in the third quarter of 2016. Average money market deposits increased by $34.1 million, or 5.57% and the cost of money market deposits was 0.59% for the for the third quarter of 2017 compared to 0.44% for the 2016 quarterly period.  The cost of certificates of deposit increased 4 basis point to 1.18% for the three months ended September 30, 2017 compared to the three months ended September 30, 2016 and the average balance increased 6.57%. The cost of savings accounts increased 2 basis points to 0.19% and the average balance increased 26.09% for the three months ended September 30, 2017 as compared to the 2016 quarter. The cost of NOW accounts was 0.06% for both periods and the average balance increased 4.09% in the three months ended September 30, 2017 compared to the same period in 2016.  The increase in interest expense on borrowings reflects the 23.73% increase in average balance partially offset by the decrease in cost to 1.84% from 2.00% when comparing the three months ended September 30, 2017 and 2016.

Compared to the first nine months of 2016, interest expense increased $1.3 million, or 12.58% to $11.6 million from $10.3 million reflecting the quarter over quarter trend of increasing deposit average balances. Average interest bearing deposits increased $164.2 million, or 10.89% and the cost of funds increased 5 basis points year over year. The increase in interest expense on borrowings is due to the average balance increase of $32.5 million, or 13.22% partially offset by a  29 basis point decrease in the cost of borrowed funds.

Net Interest and Dividend Income.    Net interest and dividend income on a tax equivalent basis increased $3.4 million, or 21.06%, to $19.3 million for the three months ended September 30, 2017 from $16.0 million for the three months ended September 30, 2016. Growth in higher yielding commercial loans was primarily funded with deposit growth. The tax equivalent net interest spread increased 13 basis points to 2.91% for the three months ended September 30, 2017 from 2.78% for the three months ended September 30, 2016, and net interest margin on a tax equivalent basis rose by 14 basis points to 3.07% for the three months ended September 30, 2017 from 2.93% for the three months ended September 30, 2016. Excluding the commercial prepayment penalty, the net interest spread and yield for the three months ended September 30, 2017 would have been 2.80% and 2.96%, respectively.

Compared to the first nine months of 2016, net interest and dividend income increased $10.2 million, or 22.92% to $54.9 million from $44.4 million.  The tax equivalent net interest spread increased 19 basis points to 2.88% for the nine months ended September 30, 2017 from 2.69% for the nine months ended September 30, 2016, and net interest margin on a tax equivalent basis also rose by 22 basis points to 3.04% for the nine months ended September 30, 2017 from 2.82% for the nine months ended September 30, 2016. Excluding the commercial prepayment penalty the net interest spread and yield for the nine months ended September 30, 2017 would have been 2.85% and 3.00%, respectively.

Results of Operations for the Three and Nine Months Ended September 30, 2017 and 2016

Net Income.    The Bank’s net income increased by $653,000 to $2.4 million for the three months ended September 30, 2017 from $1.8 million for the three months ended September 30, 2016 and, pre-tax income was $3.8

Management’s Discussion and Analysis

million for the three months ended September 30, 2017, a $1.3 million increase from the three months ended September 30, 2016. The increases in pre-tax income reflects a $2.8 million increase in net interest income and a $789,000 decrease in the provision for loan losses, partially offset by a $109,000 decrease in noninterest income and a $2.1 million increase in noninterest expense.  The provision for income taxes increased $654,000 offsetting the pre-tax income increase for the quarter.

Compared to the first nine months of 2016, the Bank’s net income for the nine months ended September 30, 2017 increased $4.3 million to $7.6 million from $3.3 million. The increase in net income reflects an increase of $9.8 million of net interest and dividend income, a decrease of $1.1 million in provision for loan losses and an increase of $90,000 in noninterest income, partially offset by increases of $3.8 million in noninterest expense and $2.9 million in provision for income taxes.

Provision for Loan Losses.    The Bank recorded a provision for loan losses of $921,000 and $1.7 million for the three and nine months ended September 30, 2017, respectively, and $1.7 million and $2.7 million for the three and nine months ended September 30, 2016. The provision reflects the continued growth in commercial loans and general reserve adjustments based on peer data utilized for commercial real estate and commercial loans. Annually, in the first quarter, the Bank adjusts general reserve allocations for commercial real estate and commercial loans based on updated peer data. The 2017 updated peer data resulted in lower general reserve rates and reserves on these loan types and therefore, despite loan growth, the allowance for loan losses attributable to commercial real estate and commercial loans decreased in the first quarter of 2017. Similarly, in 2016 improved peer data resulted in lower general reserve rates and reserves on commercial real estate and commercial loans.  Net charge-offs were $169,000 and $691,000 for the three and nine months ended September 30, 2017, respectively,  compared to $317,000 and $584,000 for the same periods in 2016 and  credit quality improved as nonaccrual loans declined to $19.6 million at September 30, 2017 from $24.0 million at September 30, 2016.

Noninterest Income.    Total noninterest income decreased to $4.7 million for the three months ended September 30, 2017 compared to $5.5 million for the prior year period. Income from mortgage banking operations decreased $827,000, or 55.47%, to $664,000 for the three months ended September 30, 2017 compared to $1.5 million for the three months ended September 30, 2016. Other mortgage banking income decreased $502,000 compared to the three months ended September 30, 2016 primarily a result of lower residential real estate loan sale volume in 2017 as compared to 2016. The fair value adjustment of mortgage servicing rights was a $170,000 loss in 2017 compared to a gain of $155,000 during the three months ended September 30, 2016, driven by the market rate changes during the periods. Other noninterest income was flat at $4.0 million for the three months ended September 30, 2017 and September 30, 2016. 

Compared to the first nine months of 2016, total noninterest income for the nine months ended September 30, 2017 decreased $590,000, or 4.05%, to $14.0 million from $14.6 million. Total mortgage banking income decreased $627,000 as other mortgage banking income decreased of $1.1 million partially offset by the $504,000 decrease in the fair value loss on the mortgage servicing rights. The low rate environment of 2016 negatively impacted servicing rights values and positively impacted mortgage loan origination volumes. Other noninterest income was flat at $12.2 million for the nine months ended September 30, 2017 and 2016. 

Noninterest Expense.    Noninterest expense increased $2.1 million, or 12.79%, to $18.7 million for the three months ended September 30, 2017 from $16.6 million for the three months ended September 30, 2016. The increase in noninterest expense included increased compensation and benefit expense of $973,000, marketing expenses increase of $578,000, professional fee increase of $359,000 and occupancy and equipment expense increase of $268,000. The increase in compensation and benefits expense is due to annual salary increases, staff additions to the commercial loan area, and equity awards expense of $498,000.  The equity awards were granted in the third quarter of 2017. The increase in professional fees primarily reflects expenses related to tax and other consulting.

Compared to the first nine months of 2016, noninterest expense for the nine months ended September 30, 2017 increased $3.8 million, or 7.49% to $53.9 million from $50.2 million. The components of the year-to-date increase include increased salaries and benefit costs of $1.6 million, primarily due to ESOP expense of $716,000 and equity awards expense

of $498,000, increased professional fees of $968,000 primarily related to tax and other consulting, increased occupancy and equipment expense of $576,000 and increased marketing expense of $912,000.

Income Tax Provision.    Provision for income taxes for the three and nine months ended September 30, 2017 was $1.4 million and $4.3 million, respectively, compared to $739,000 and $1.5 million for the three and nine months ended September 30, 2016, respectively. The increased provision for income taxes was mainly due to increase in pre-tax earnings of $1.3 million and $7.2 million for the three and nine months ended September 30, 2017 and an increase in the effective rate. The increase in the effective tax rate in 2017 is due primarily to the increase in nondeductible expense related to the ESOP and decreased tax-advantaged income.

Management’s Discussion and Analysis

For the three and nine months ended September 30, 2017, Merrimack Mortgage originated $296.8 million and $764.7 million, respectively, of residential mortgages.  For the three and nine months ended September 30, 2016, Merrimack Mortgage originated $422.4 and $992.7 million, respectively, of residential mortgages. The decrease is due primarily to higher mortgage rates in 2017.  The following tables provide additional loan production detail:

During the three and nine months ended September 30, 2017, Merrimack Mortgage sold loans to Freddie Mac, Fannie Mae and Ginnie Mae in the amounts of $43.1 million and $169.9 million, respectively, and recorded an average originated mortgage servicing right gain of 0.92% and 0.93%, respectively, of the underlying mortgage amount.  For the

Management’s Discussion and Analysis

three and nine months ended September 30, 2016, there were $239.0 million and $581.4 million, respectively, of agency loan sales at an average originated mortgage servicing right gain of 1.01%. The decrease in pricing of the mortgage servicing rights resulted in the decrease agency sales.

For the three and nine months ended September 30, 2017 processing, underwriting, and closing fees amounted to  $1.0 million and $2.6 million, respectively, as compared to $2.2 million and $5.1 million for the three and nine months ended September 30, 2016, reflecting the lower production volumes of 2017. Secondary market loan servicing fees, net of loan guarantee fees were $907,000 and $2.7 million, respectively for the three and nine months ended September 30, 2017 as compared to $698,000 and $1.4 million, respectively for the three and nine months ended September 30, 2016. At September 30, 2017, the unpaid balance of the servicing portfolio totaled $1.4 billion as compared to $1.09 billion at September 30, 2016, resulting in the higher secondary market servicing fees in 2017.  

During the three months ended September 30, 2017 the fair value of mortgage servicing rights decreased $318,000 and the 10 year Treasury Constant Maturity rate increased 2 basis points. For the same quarter in 2016 the fair value of mortgage servicing rights increased $196,000 and the 10 year Treasury Constant Maturity rate increased 11 basis points.  During the nine months ended September 30, 2017 and 2016, the fair value of mortgage servicing rights decreased $1.3 million and $2.9 million, respectively, reflecting decreases in the 10 year Treasury Constant Maturity rate of 12 basis points and 67 points, respectively. Decreasing interest rates generally result in a decrease in mortgage servicing rights fair value as the assumed prepayment speeds of the underlying mortgage loans tend to increase.  Conversely, as interest rates rise and prepayment speeds slow, mortgage servicing rights fair value tend to increase. In the current quarter, prepayment speeds on the serviced portfolio were slightly higher, impacted by low mortgage demand on rising housing prices and rates, resulting in the decrease in value.

Noninterest Expense.    Noninterest expense for the three months ended September 30, 2017 and 2016 was $9.5 million and $12.9 million, respectively, generally reflecting the decreased loan volume. Compensation and benefits expenses totaled $6.8 million and $9.1 million, respectively, for the three months ended September 30, 2017 and 2016. Salary expense was $2.2 million and $2.3 million, commission-related expenses were $4.0 million and $5.5 million, and incentive plan expense was $89,000 and $678,000, respectively, for the three months ended September 30, 2017 and 2016. Loan expenses totaled $1.6 million and $2.9 million for the three months ended September 30, 2017 and 2016, and included direct loan origination expenses of $1.3 million and $2.5 million, respectively, associated with the origination of $296.8 million and $422.4 million of mortgage loans.  Sub-servicing related expenses for the same three month periods were $246,000 and $189,000, respectively. Occupancy expense totaled $628,000 and $407,000 for the three months ended September 30, 2017 and 2016, and primarily consisted of rent and other expenses associated with the retail branch network and corporate office. Other expenses totaled $472,000 and $578,000 for the three months ended September 30, 2017 and 2016 and primarily consisted of professional fees and other expenses. The quarter over quarter decrease reflects decreased professional fees and marketing expense.

Noninterest expense for the nine months ended September 30, 2017 and 2016 was $25.4 million and $30.3 million, respectively. Salary and benefits was $18.4 million including $6.4 million in salary expense and $10.1 million in commission related expenses for the nine months ended September 30, 2017 as compared to $21.7 million including $6.4 million in salary expense and $12.7 million in commission related expenses for the nine months ended September 30, 2016.  Loan expenses totaled $4.1 million and $5.9 million for the nine months ended September 30, 2017 and 2016, respectively.  Included in loan expense was direct loan origination expense of $3.2 million and $5.3 million, respectively, associated with the origination of mortgage loans of $764.7 million and $992.7 million, respectively. Sub-servicing related expenses were $641,000 and $487,000, respectively.  Occupancy expense was $1.6 million and $1.3 million, respectively for the nine months ended September 30, 2017 and 2016. Other expenses totaled $1.3 million and $1.4 million for the nine months ended September 30, 2017 and 2016 and primarily consisted of professional fees and other expenses.

Management’s Discussion and Analysis

At September 30, 2017, our allowance for loan losses was $17.9 million, or 0.84% of total loans and 91.47% of nonperforming loans. At December 31, 2016, our allowance for loan losses was $17.0 million, or 0.85% of total loans and 80.12% of nonperforming loans. Nonperforming loans at September 30, 2017 were $19.6 million, or 0.92% of total loans, compared to $21.2 million, or 1.06% of total loans, at December 31, 2016. The allowance for loan losses is maintained at a level that represents management’s best estimate of losses in the loan portfolio at the balance sheet date. However, there can be no assurance that the allowance for loan losses will be adequate to cover losses which may be realized in the future or that additional provisions for loan losses will not be required.

We recorded a provision for loan losses of $921,000 and $1.7 million for the three months ended September 30, 2017 and 2016, respectively. For the nine months ended September 30, 2017 and 2016, we recorded a provision for loan losses of $1.7 million and $2.7 million, respectively. The provisions primarily reflect loan loss allocations commensurate with commercial loan growth and other changes in the loan portfolio. Annually, in the first quarter, the Company adjusts general reserve allocations for commercial real estate and commercial loans based on updated peer data. The updated peer data resulted in lower general reserve rates and reserves on these loan types however, the decrease was partially offset by commercial loan growth. Changes in the provision for loan losses are also based on management’s assessment of loan portfolio growth and composition changes, historical charge-off trends, and ongoing evaluation of credit quality and current economic conditions. Net charge-offs totaled $169,000 for the quarter ended September 30, 2017, or 0.03%, of average loans outstanding on an annualized basis, compared to $317,000 and 0.07% for the quarter ended September 30, 2016. Nonperforming assets were $20.6 million at September 30, 2017 compared to $22.9 million at December 31, 2016 and $26.0 million at September 30, 2016. Nonperforming assets as a percentage of total assets were 0.78% at September 30, 2017, 0.94% at December 31, 2016 and 1.11% at September 30, 2016. The continued improvement in assets quality reflects the Company’s continued efforts to minimize nonperforming assets through diligent collection efforts and prudent workout arrangements.

Management’s Discussion and Analysis

Management of Market Risk

Net Interest Income Analysis.  The Company uses income simulation as the primary tool for measuring interest-rate risk inherent in our balance sheet at a given point in time by showing the effect on net interest income, over specified time frames and using different interest rate shocks and ramps. The assumptions include, but are not limited to, management’s best assessment of the effect of changing interest rates on the prepayment speeds of certain assets and liabilities, projections for account balances in each of the product lines offered and the historical behavior of deposit rates and balances in relation to changes in interest rates. These assumptions are inherently changeable, and as a result, the model is not expected to precisely measure net interest income or precisely predict the impact of fluctuations in interest rates on net interest income. Actual results will differ from the simulated results due to timing, magnitude, and frequency of interest rate changes as well as changes in the balance sheet composition and market conditions. Assumptions are supported with quarterly back testing of the model to actual market rate shifts.

As of September 30, 2017, net interest income simulation results for the Company indicated that our exposure over one year to changing interest rates was within our guidelines. The following table presents the estimated impact of interest rate changes on our estimated net interest income over one year:

September 30, 2017
	Change in Net Interest Income
Changes in Interest Rates	Year One
(basis points) (1)	(% change from year one base)
+300	3.62	%
(100)	(4.46)	%
(1) The calculated change in net interest income assumes an instantaneous parallel shift of the yield curve.

Economic Value of Equity Analysis.  The Company also uses the net present value of equity at risk, or "EVE," methodology. This methodology calculates the difference between the present value of expected cash flows from assets and liabilities. The comparative scenarios assume an immediate parallel shift in the yield curve up 300 basis points and down 100 basis points.

The board of directors and management review the methodology’s measurements for both net interest income and EVE on a quarterly basis to determine whether the exposure resulting from the changes in interest rates remains within established tolerance levels and develops appropriate strategies to manage this exposure.

The table below sets forth, as of September 30, 2017, the estimated changes in the net economic value of equity that would result from the designated changes in the United States Treasury yield curve under an instantaneous parallel shift for the Bank. Computations of prospective effects of hypothetical interest rate changes are based on numerous

Liquidity Management and Capital Resources

Liquidity is the ability to meet current and future financial obligations of a short-term and long-term nature. Our primary sources of funds consist of deposit inflows, loan repayments, maturities and sales of securities, and borrowings from the FHLB. While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows, calls of investment securities and borrowed funds and prepayments on loans are greatly influenced by general interest rates, economic conditions and competition.

Management regularly adjusts our investments in liquid assets based upon an assessment of (1) expected loan demand, (2) expected deposit flows, (3) yields available on interest-earning deposits and securities, and (4) the objectives of our interest rate risk and investment policies.

Our cash flows are composed of three primary classifications: cash flows from operating activities, investing activities and financing activities. Net cash provided by operating activities was $3.0 million for the nine months ended September 30, 2017 as compared to net cash used by operating activities of $39.5 million for the nine months ended September 30, 2016. Net cash used in investing activities, which consists primarily of disbursements for loan originations and loan purchases, the purchase of securities and the purchase of time deposits with other banks, offset by principal collections on loans, proceeds from the sale of securities, proceeds from redemption of time deposits and proceeds from maturing securities and sales of other real estate owned, and pay downs on mortgage-backed securities, was $158.9 million and $150.6 million for the nine months ended September 30, 2017 and 2016, respectively. Net cash provided by financing activities, consisting primarily of the activity in deposit accounts, FHLB advances and the issuance of common stock was $200.5 million and $168.7 million for the nine months ended September 30, 2017 and 2016, respectively, resulting from our strategy of managing growth and cash flows to preserve capital ratios and reduce expenses.

The Bank is subject to various regulatory capital requirements. At September 30, 2017, the Bank exceeded all regulatory capital requirements and was considered “well capitalized” under regulatory guidelines. See Note 11 to our unaudited interim Consolidated Financial Statements included in Part I, Item 1 of this Form 10-Q.

At September 30, 2017, we had outstanding commitments to originate loans of $99.1 million and unadvanced funds on loans of $261.9 million. We anticipate that we will have sufficient funds available to meet our current loan origination commitments. Certificates of deposit that are scheduled to mature in less than one year from September 30, 2017 totaled $369.1 million. Management expects, based on historical experience, that a substantial portion of the maturing certificates of deposit will be renewed. However, if a substantial portion of these deposits is not retained, we may use FHLB advances, brokered deposits, or raise interest rates on deposits to attract new accounts, which may result in higher levels of interest expense.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

1.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Consolidation

The unaudited interim Consolidated Financial Statements of HarborOne Bancorp, Inc. (the “Company”) presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by the U.S. generally accepted accounting principles (“GAAP”).  In the opinion of management, all adjustments and disclosures considered necessary for the fair presentation of the accompanying Consolidated Financial Statements have been included.  Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2016 and 2015 and notes thereto included in the Company’s Annual Report on Form 10-K.

The unaudited interim Consolidated Financial Statements include the accounts of the Company, the Company’s subsidiaries Legion Parkway Company LLC, a security corporation formed on July 13, 2016 and HarborOne Bank (the “Bank”); and the Bank’s wholly-owned subsidiaries.  The Bank’s subsidiaries consist of a mortgage company and two security corporations.  Merrimack Mortgage Company, LLC (“Merrimack Mortgage”) was acquired and became a wholly-owned subsidiary of the Bank on July 1, 2015.  The security corporations were established for the purpose of buying, holding and selling securities on their own behalf.  All significant intercompany balances and transactions have been eliminated in consolidation.

Stock Conversion

On June 29, 2016, the Bank reorganized into a two-tier mutual holding company structure with a mid-tier stock holding company. The Company sold 14,454,396 shares of common stock at $10.00 per share, including 1,187,188 shares purchased by the Company’s Employee Stock Ownership Plan (“ESOP”). In addition, the Company issued 17,281,034 shares to HarborOne Mutual Bancshares, a mutual holding company (the “MHC”) and 385,450 shares to The HarborOne Foundation,a charitable foundation formed in connection with the stock offering and dedicated to supporting charitable organizations operating in the Bank’s local community. A total of 32,120,880 shares of common stock were outstanding following the completion of the stock offering. The direct costs of the Company’s stock offering of $3.9 million were deferred and deducted from the proceeds of the offering. 

Upon the completion of the stock offering, a special “liquidation account” was established for the benefit of certain depositors of the Bank in an amount equal to the percentage ownership interest in the equity of the Company held by persons other than the MHC as of the date of the latest balance sheet contained in the prospectus. The Company is not permitted to pay dividends on its capital stock if the Company’s shareholders’ equity would be reduced below the amount of the liquidation account. The liquidation account will be reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases in an eligible account holder’s qualifying deposits will not restore such holder’s interest in the liquidation account.

Nature of Operations

The Company provides a variety of financial services to individuals and businesses through its fourteen full-service and two limited-service bank offices in eastern Massachusetts, a commercial lending office in Providence, Rhode Island, and a loan office in Westford, Massachusetts.  Merrimack Mortgage maintains 33 offices in Massachusetts, New Hampshire, and Maine, and is also licensed to lend in seven additional states. 

The Company’s primary deposit products are checking, money market, savings and term certificate of deposit accounts while its primary lending products are commercial real estate, commercial, residential mortgages and consumer loans, including indirect automobile lending. The Company also originates, sells and services residential mortgage loans primarily through Merrimack Mortgage.

Use of Estimates

In preparing unaudited interim Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuations of mortgage servicing rights, derivatives, goodwill and deferred tax assets. 

Allowance for Loan Losses

The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings.  Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed and generally do not exceed the time frame provided in the FDIC’s Uniform Retail Credit Classification and Account Management Policy.  Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a regular basis by management.  This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.  The allowance consists of general, allocated and unallocated components, as further described below.

General component

The general component of the allowance for loan losses is based on historical loss experience adjusted for qualitative factors stratified by the Company’s loan segments.  Management uses arolling average of historical losses based on a time frame appropriate to capture relevant loss data for each loan segment except commercial real estate and commercial loans.  Due to the lack of historical loss experience for our commercial real estate and commercial loan portfolio, we utilize peer loss data.  Adjustments to this historical loss factor are considered for the following qualitative factors: levels/trends in delinquencies; trends in volume and terms of loans; effects of changes in risk selection and underwriting standards and other changes in lending policies, procedures and practices; experience/ability/depth of lending management and staff; and national and local economic trends and conditions.  There were no changes in the Company’s policies or methodology pertaining to the general component of the allowance for loan losses during 2016 or the nine months ended September 30, 2017.  The qualitative factors are determined based on the various risk characteristics of each loan segment.  Risk characteristics relevant to each portfolio segment are as follows:

Residential real estate – The Company generally does not originate portfolio loans with a loan-to-value ratio greater than 80 percent without obtaining private mortgage insurance and does not generally grant loans that would be classified as subprime upon origination.  The Company generally has first or second liens on property securing equity lines of credit.  Loans in this segment are generally collateralized by residential real estate and repayment is dependent on the credit quality of the individual borrower.  The overall health of the economy, including unemployment rates and housing prices, can have an effect on the credit quality in this segment.  

Commercial real estate – Loans in this segment are primarily secured by income-producing properties in southeastern New England.  The underlying cash flows generated by the properties can be adversely impacted by a downturn in the economy as evidenced by increased vacancy rates, which in turn, could have an effect on the credit quality in this segment.  Management obtains rent rolls annually and continually monitors the cash flows of these loans.

Construction – Loans in this segment include both residential and commercial construction loans.  Residential construction loans include loans to build one- to four-family owner-occupied properties, which are subject to the same credit quality factors as residential real estate loans.  Commercial construction loans may include speculative real estate development loans for which payment is derived from lease or sale of the property.  Credit risk is affected by cost overruns, time to lease or sell at an adequate price, and market conditions.

Commercial – Loans in this segment are made to businesses and are generally secured by assets of the business.  Repayment is expected from the cash flows of the business.  A weakened economy, and resultant decreased consumer or business spending, could have an effect on the credit quality in this segment.  

Consumer – Loans in this segment are generally secured by automobiles or unsecured and repayment is dependent on the credit quality of the individual borrower.

Allocated component

The allocated component relates to loans that are classified as impaired.  Residential real estate, commercial, commercial real estate and construction loans are evaluated for impairment on a loan-by-loan basis.  Impairment is determined by nonaccrual status, whether a loan is subject to a troubled debt restructuring agreement or in the case of certain loans, based on the internal credit rating.  Large groups of smaller balance homogeneous loans are collectively evaluated for impairment.  Accordingly, except for troubled debt restructuring (“TDR”), the Company does not separately identify individual consumer loans for impairment evaluation. 

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement.  Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due.  Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired.  Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. 

The Company periodically may agree to modify the contractual terms of loans.  When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a TDR.  All TDRs are initially classified as impaired.  Impairment is measured by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent.  An allowance is established when the discounted cash flows or collateral value of the impaired loan is lower than the carrying value of that loan.

Unallocated component

The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating allocated and general reserves in the portfolio. The unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. Additionally the Company's unseasoned commercial portfolio and use of peer group data to establish general reserves for the commercial portfolio adds another element of risk to management's estimates.

Stock-based Compensation Plans

The Company’s stock-based compensation plans provide for awards of stock options, restricted stock and other stock-based compensation to directors, officers and employees.  The cost of employee services received in exchange for awards of equity instruments is based on the grant-date fair value of those awards.  Compensation cost is recognized over the requisite service period as a component of compensation expense.  The Company uses the Black-Scholes option-pricing model to determine the fair value of stock options granted, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. The Company has elected to early adopt Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.Under this Update, the Company has elected to account for forfeitures of share-based payments by recognizing forfeitures of awards as they occur (e.g., when an award does not vest because the employee leaves the Company or does not meet specific performance measures).

Earnings Per Share

Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period.  Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. The restricted stock awards are participating securities; therefore unvested awards are included as common shares outstanding in the computation of basic earnings per share. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate to outstanding stock options awards and are determined using the treasury stock method.

Recent Accounting Pronouncements

As an “emerging growth company” as defined in Title 1 of the Jumpstart Our Business Startups (JOBS) Act, the Company has elected to use the extended transition period to delay the adoption of new or reissued accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies.  As of September 30, 2017, there is no significant difference in the comparability of the financial statements as a result of this extended transition period.

In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. This guidance changes the recognition and presentation requirements of hedge accounting, including eliminating the requirement to separately measure and report hedge ineffectiveness and presenting all items that affect earnings in the same income statement line as the hedged item. This guidance also provides new alternatives for applying hedge accounting to additional hedging strategies, measuring the hedged item in fair value hedges of interest rate risk, reducing the complexity of applying hedge accounting by easing the requirements for effectiveness testing, hedge documentation and application of the critical terms match method, and reducing the risk of material error corrections if a company applies the shortcut method inappropriately.  This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company does not have any derivatives within the scope of the ASU.

In March 2017, the FASB issued ASU 2017-08, Receivables- Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The Company elected to early adopt this new accounting guidance effective January 1, 2017 and the adoption did not have a material impact on the Consolidated Financial Statements.

In January 2017, FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.  This update changes the quantitative impairment test to require an entity to perform a one-step test and record the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value, not to exceed the amount of goodwill allocated to the reporting unit.  This new guidance does not amend the optional qualitative assessment of goodwill impairment.  For SEC filers, the ASU is effective for impairment tests in fiscal years beginning after December 15, 2019.  For non-public business entities, the ASU is effective for impairment tests in fiscal years beginning after December 15, 2021.  Early adoption is permitted for impairment tests performed on testing dates after January 1, 2017.  The Company elected to early adopt this new accounting guidance effective October 1, 2017 and the adoption did not have an impact on the Consolidated Financial Statements.

In June 2016, FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), which requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts.  Entities will now use forward-looking information to better form their credit loss estimates.  The ASU also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio.  For public entities that are SEC filers, this ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.  For non-public entities, this ASU is effective for fiscal years beginning after December 15, 2020, and for interim periods within fiscal years beginning after December 15, 2021.  Early application will be permitted for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018.  Management has identified an implementation team that is in the process of developing an understanding of this pronouncement, evaluating the impact of this pronouncement and researching additional software resources that could assist with the implementation.

In February 2016, FASB issued ASU 2016-02,  Leases (Topic 842).  This update requires a lessee to record a right-to-use asset and a liability representing the obligation to make lease payments for long-term leases.  For public business entities, this update is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  For non-public business entities, this update is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years beginning after December 15, 2020.  While we are currently evaluating the impact of the new standard, we expect an increase to the Consolidated Balance Sheets for right-of-use assets and associated lease liabilities but no material impact to the Consolidated Statement of Operations, for arrangements previously accounted for as operating leases.

In January 2016, FASB issued ASU 2016-01, Financial Instruments – Overall, (Subtopic 825-10).  The amendments in this update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments.  Targeted improvements to generally accepted accounting principles include the requirement for equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, the elimination of the requirement for non-public business entities to disclose the fair value of financial instruments measured at amortized cost and the elimination of the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost.  For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years.  For non-public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019.  Management currently does not expect this to have a material impact on the Company's Consolidated Financial Statements as the Company does not currently hold any equity securities.

In May 2014, FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The amendments in this update create Topic 606, Revenue from Contracts with Customers, and supersede the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve the core principle, a company should apply a five step approach to revenue recognition. For public business entities, this ASU is effective for annual reporting periods, including interim periods, beginning after December 15, 2017. For non-public business entities, this ASU is effective for annual reporting periods beginning after December 31, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early application is permitted, but only for annual reporting periods beginning after December 15, 2016. The Bank's primary source of revenue is interest income on financial assets and income from mortgage banking activities, which are explicitly excluded from the scope of the new guidance.  As a result, adoption is not expected to have a material impact on the Company’s Consolidated Financial Statements. However, the Company will continue to monitor developments and additional guidance up to the effective date of these amendments.

Management evaluates securities for other-than-temporary impairment (“OTTI”) at each reporting period, and more frequently when economic or market concerns warrant such evaluation.

At September 30, 2017, twenty-eight debt securities with an amortized cost of $89.6 million have unrealized losses with aggregate depreciation of 0.90% from the Company’s amortized cost basis. 

The unrealized losses on the Company’s securities were primarily caused by changes in interest rates.  All of these investments are guaranteed by government and government-sponsored enterprises.  Accordingly, it is expected that the securities would not be settled at a price less than the par value of the investment.  Because the decline in fair value is attributable to changes in interest rates and not to credit quality, and because the Company does not intend to sell the investments and it is more likely than not that the Company will not be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider these investments to be OTTI at September 30, 2017.

During the nine months ended September 30, 2017, the Company sold indirect auto loans of $5.0 million. The loans were classified as loans held for sale at March 31, 2017 and a gain of $78,000 was recorded in the first quarter.  During the nine months ended September 30, 2016, the Company sold $10.0 million of indirect loans and recognized gains of $79,000.  No indirect auto loans were sold during the three months ended September 30, 2017 and 2016.  The unpaid principal balance of indirect auto loans serviced for others was $25.5 million and $31.4 million at September 30, 2017 and December 31, 2016, respectively. 

The Company did not sell residential portfolio loans during the three or nine months ended September 30, 2017. The Company sold residential portfolio loans of $29.5 million during the nine months ended September 30, 2016.  Included in mortgage banking income for the nine months ended September 30, 2016is the related gain on sale of $501,000.  No residential loans were sold from the portfolio during the three months ended September 30, 2016.

The Company has transferred a portion of its originated commercial real estate loans to participating lenders.  The amounts transferred have been accounted for as sales and are therefore not included in the Company’s accompanying unaudited interim Consolidated Balance Sheets.  The Company and participating lenders share ratably in cash flows and any gains or losses that may result from a borrower’s lack of compliance with contractual terms of the loan.  The Company continues to service the loans on behalf of the participating lenders and, as such, collects cash payments from the borrowers, remits payments to participating lenders and disburses required escrow funds to relevant parties.  At September 30, 2017 and December 31, 2016, the Company was servicing loans for participants aggregating $62.1 million and $45.3 million, respectively.

Interest income recognized and interest income recognized on a cash basis in the table above represents interest income for the three and nine months ended September 30, 2017 and 2016, not for the time period designated as impaired.  As part of a workout agreement, the Company is committed to advance $165,000 in additional funds on one commercial impaired loan.

The following table sets forth TDRs during the three and nine months ended September 30, 2017 and 2016:

There were no TDR loan modifications for the three months ended September 30, 2016.

The recorded investment in TDRs was $29.7 million and $31.8 million at September 30, 2017 and 2016, respectively.  Of these loans, $8.1 million and $6.8 million were on non-accrual at September 30, 2017 and 2016, respectively.

All TDR loans are considered impaired and management performs a discounted cash flow calculation to determine the amount of impairment reserve required on each loan.  TDR loans which subsequently default are reviewed to determine if the loan should be deemed collateral dependent.  In either case, any reserve required is recorded as part of the allowance for loan losses.

During the three and nine months ended September 30, 2017, there were no payment defaults on TDRs.  During the nine months ended September 30, 2016, one troubled debt restructuring with a recorded investment of $107,000 defaulted.  During the three months ended September 30, 2016, there were no payment defaults on TDRs.

Credit Quality Information

The Company uses a ten grade internal loan rating system for commercial real estate, commercial construction and commercial loans, as follows:

Loans rated 1 – 6 are considered “pass” rated loans with low to average risk.

Loans rated 7 are considered “special mention.”  These loans are starting to show signs of potential weakness and are being closely monitored by management. 

Loans rated 8 are considered “substandard.”  Generally, a loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged.  There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected.

Loans rated 9 are considered “doubtful.”  Loans classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable.

Loans rated 10 are considered “uncollectible” (loss), and of such little value that their continuance as loans is not warranted. 

Loans not rated consist primarily of residential construction loans and certain smaller balance commercial real estate and commercial loans that are managed by exception. 

On an annual basis, or more often if needed, the Company formally reviews on a risk adjusted basis, the ratings on all commercial real estate, construction and commercial loans.  Semi-annually, the Company engages an independent third party to review a significant portion of loans within these segments.  Management uses the results of these reviews as part of its annual review process. 

On a monthly basis, the Company reviews the residential construction, residential real estate and consumer installment portfolios for credit quality primarily through the use of delinquency reports.

The following table presents the Company’s loans by risk rating at September 30, 2017 and December 31, 2016:

MORTGAGE LOAN SERVICING

MORTGAGE LOAN SERVICING

4.MORTGAGE LOAN SERVICING

The Company sells residential mortgages to government-sponsored entities and other parties.  The Company retains no beneficial interests in these loans, but may retain the servicing rights of the loans sold.  Mortgage loans serviced for others are not included in the accompanying unaudited interim Consolidated Balance Sheets.  The risks inherent in mortgage servicing rights (“MSRs”) relate primarily to changes in prepayments that primarily result from shifts in mortgage interest rates.  The unpaid principal balances of mortgage loans serviced for others were $1.92 billion and $1.85 billion as of September 30, 2017 and December 31, 2016, respectively. 

The Company accounts for MSRs at fair value.  The Company obtains valuations from independent third parties to determine the fair value of MSRs.  Key assumptions used in the estimation of fair value include prepayment speeds, discount rates, default rates, cost to service, and contractual servicing fees.  At September 30, 2017 and December 31, 2016, the following weighted average assumptions were used in the calculation of fair value of MSRs:

	September 30,		December 31,
	2017		2016
Prepayment speed	10.29	%	9.49	%
Discount rate	9.26		9.25
Default rate	2.02		1.71

The following summarizes changes to mortgage servicing rights for the nine months ended September 30, 2017 and 2016:

For the three months ended September 30, 2017 and 2016, contractually specified servicing fees included in other mortgage banking income amounted to $1.3 million and $1.1 million, respectively.  For the nine months ended September 30, 2017 and 2016, contractually specified servicing fees included in other mortgage banking income amounted to $3.9 million and $2.9 million, respectively.

8.OTHER COMMITMENTS AND CONTINGENCIES

Loan Commitments

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers.  These financial instruments include commitments to extend credit and advance funds on various lines of credit.  Those commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the accompanying unaudited interim Consolidated Financial Statements.

The Company’s exposure to credit loss is represented by the contractual amount of these commitments.  The Company uses the same credit policies in making commitments as it does for on-balance sheet instruments.

The following off-balance sheet financial instruments were outstanding at September 30, 2017 and December 31, 2016.  The contract amounts represent credit risk.

	September 30,		December 31,
	2017		2016
	(in thousands)
Commitments to grant loans	$	99,062	$	75,914
Unadvanced funds on home equity lines of credit		79,410		82,797
Unadvanced funds on revolving lines of credit		65,676		58,238
Unadvanced funds on construction loans		116,766		49,999

Commitments to extend credit and unadvanced portion of construction loans are agreements to lend to a customer, as long as there is no violation of any condition established in the contract.  Commitments to grant loans generally have fixed expiration dates or other termination clauses and may require payment of a fee.  The commitments for unadvanced funds on construction loans, home equity and revolving lines of credit may expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements.  The Company evaluates each customer’s credit worthiness on a case-by-case basis.  Commitments to grant loans, and unadvanced construction loans and home equity lines of credit are collateralized by real estate, while revolving lines of credit are unsecured.

Other Commitments

On May 31, 2017, the Bank entered into a ground lease for property located in Stoughton, Massachusetts, to develop as a prospective branch site.  Until January 31, 2018, the Bank has the right to terminate the lease without any future obligations.

DERIVATIVES

DERIVATIVES

9.DERIVATIVES

The Company is party to a variety of derivative transactions, including derivative loan commitments, forward loan sale commitments and interest rate swap contracts. The Company enters into derivative contracts in order to meet the financing needs of its customers. The Company also enters into derivative contracts as a means of reducing its interest rate risk and market risk. 

All derivatives are recognized in the unaudited interim Consolidated Balance Sheets at fair value.  Changes in the fair value of derivatives are recognized in earnings.  The Company did not have any fair value hedges or cash flow hedges at September 30, 2017 and December 31, 2016. 

Derivative Loan Commitments

Mortgage loan commitments qualify as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding.  The Company enters into commitments to fund residential mortgage loans at specified times in the future, with the intention that these loans will subsequently be sold in the secondary market.  A mortgage loan commitment binds the Company to lend funds to a potential borrower at a specified interest rate and within a specified period of time, generally up to 60 days after inception of the rate lock.

Outstanding derivative loan commitments expose the Company to the risk that the price of the loans arising from exercise of the loan commitment might decline from inception of a rate lock to funding of the loan due to increases in mortgage interest rates.  If interest rates increase, the value of these loan commitments decreases.  Conversely, if interest rates decrease, the value of these loan commitments increases. 

Forward Loan Sale Commitments

The Company utilizes both “mandatory delivery” and “best efforts” forward loan sale commitments to mitigate the risk of potential decreases in the values of loans that would result from the exercise of the derivative loan commitments. 

With a “mandatory delivery” contract, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date.  If the Company fails to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, it is obligated to pay a “pair-off” fee, based on then-current market prices, to the investor to compensate the investor for the shortfall.

With a “best efforts” contract, the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes.  Generally, the price the investor will pay the seller for an individual loan is specified prior to the loan being funded (e.g., on the same day the lender commits to lend funds to a potential borrower).

The Company expects that these forward loan sale commitments will experience changes in fair value opposite to the change in fair value of derivative loan commitments. 

Interest Rate Swaps

The Company enters into interest rate swap agreements that are transacted to meet the financing needs of its commercial customers. Offsetting interest rate swap agreements are simultaneously transacted with a third-party financial institution to effectively eliminate the Company’s interest rate risk associated with the customer swaps. The primary risks associated with these transactions arise from exposure to the ability of the counterparties to meet the terms of the contract.  Mortgage-backed securities with a fair value of $5.9 million are pledged to secure the Company’s liability for the offsetting interest rate swaps (see Note 2).  The interest rate swap notional amount below is the aggregate notional amount of the customer swap and the offsetting third-party swap.

Risk Participation Agreements

The Company has entered into risk participation agreements with the correspondent institutions and shares in any interest rate swap losses incurred as a result of the commercial loan customers’ termination of a loan level interest rate swap agreement prior to maturity. The Company records these risk participation agreements at fair value. The Company’s maximum credit exposure is based on its proportionate share of the settlement amount of the referenced interest rate swap.

Directors’ Retirement Plan

The Company has elected to freeze the Directors’ Retirement Plan effective December 31, 2017.  The balance of the liability at September 30, 2017 was $1.6 million.

Supplemental Retirement Plans

On March 1, 2016, in anticipation of the reorganization, the Company amended a supplemental executive retirement Plan with an executive to accelerate vesting.  This amendment increased the net present value of the benefit obligation in the amount of $891,000 and this increase was expensed in the first quarter of 2016. 

Employee Stock Ownership Plan

On June 29, 2016, the Company established an ESOP to provide eligible employees the opportunity to own Company stock. The plan is a tax-qualified retirement plan for the benefit of the Company employees.  The ESOP shares were purchased through a loan from the Company and as the debt is repaid, shares are released.  Contributions are allocated to eligible participants on the basis of compensation, subject to federal tax limits.  The unreleased shares are deducted from stockholders’ equity as unearned ESOP shares in the accompanying balance sheets.  The number of shares committed to be released per year is 59,359 through 2035. 

The following table presents share information held by the ESOP:

	September 30, 2017		December 31, 2016

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION

11.STOCK-BASED COMPENSATION

Under the HarborOne Bancorp, Inc. 2017 Stock Option and Incentive Plan (the “Equity Plan”), adopted on August 9, 2017, the Company may grant options, stock appreciation rights, restricted stock, restricted units, unrestricted stock awards, cash based awards, performance share awards, and dividend equivalent rights to its directors, officers and employees. Total shares reserved for issuance under the plan are 2,077,577. Both incentive stock options and non-qualified stock options may be granted under the Equity Plan, with the total shares reserved for options equaling 1,483,984. The exercise price of each option equals the market price of the Company’s stock on the date of grant and the maximum term of each option is ten years. The total number of shares reserved for restricted stock or restricted units is 593,593. Options and awards vest ratably over three years. The fair value of shares awarded is based on the market price at the date of grant.

Expense related to options and restricted stock granted to directors is recognized as directors' fees within noninterest expense.

The Company has standard form agreements used for stock option and restricted stock awards. The standard form agreements used for the Chief Executive Officer and all other executive officers have previously been disclosed in Securities and Exchange Commission filings and generally provide that: (1) any unvested options or unvested restricted stock vest upon a Change in Control; and, that (2) any stock options which vest pursuant to a Change in Control, which is an event described in Section 280G of the Internal Revenue Code of 1986, will be cashed out at the difference between the acquisition price and the exercise price of the stock option.

Stock Options

The fair value of each option grant is estimated on the date of the grant using the Black-Scholes option-pricing model with the following assumptions:

· Volatility is based on peer group volatility due to lack of sufficient trading history for the Company.

· Expected life represents the period of time that the option is expected to be outstanding, taking into account the contractual term and the vesting period.

· Expected dividend yield is based on the Company’s history and expectation of dividend payouts.

· Recognize forfeitures as they occur.

· The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for a period equivalent to the expected life of the option.

The Company made the following awards of options to purchase shares of common stock in 2017:

Date of grant	August 16, 2017
Options granted	1,326,063
Vesting period (years)	3
Expiration date	August 16, 2027
Expected volatility	24	%
Expected life (years)	6
Expected dividend yield	—	%
Risk free interest rate	1.88	%
Fair value per option	$ 5.07

For the quarter ended September 30, 2017, stock-based compensation expense applicable to the stock options was $282,000 and the recognized tax benefit related to this expense was $99,000.  There was no stock-based compensation expense in 2016.

Restricted Stock

Shares issued upon vesting may be either authorized but unissued shares or reacquired shares held by the Company. Any shares not issued because vesting requirements are not met will again be available for issuance under the plan. The fair market value of shares awarded, based on the market price at the date of grant, is unearned compensation to be amortized over the applicable vesting period.

The following table presents the activity in non-vested stock awards under the Equity Plan for the quarter ended September 30, 2017:

MINIMUM REGULATORY CAPITAL REQUIREMENTS

MINIMUM REGULATORY CAPITAL REQUIREMENTS

MINIMUM REGULATORY CAPITAL REQUIREMENTS

12.MINIMUM REGULATORY CAPITAL REQUIREMENTS

The Company and Bank are subject to various regulatory capital requirements administered by the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation (the “FDIC”).  Failure to meet minimum capital requirements can result in mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s Consolidated Financial Statements.

Under the capital rules, risk-based capital ratios are calculated by dividing Tier 1 and total risk-based capital, respectively, by risk-weighted assets.  Assets and off-balance sheet credit equivalents are assigned to one of several risk-weight categories, based primarily on relative risk.  The rules require banks and bank holding companies to maintain a minimum common equity Tier 1 capital ratio of 4.5%, a minimum Tier 1 capital ratio of 6.0%, a total capital ratio of 8.0% and a leverage ratio of 4.0%.  Additionally, subject to a transition schedule, the capital rules require a bank holding company to establish a capital conservation buffer of common equity Tier 1 capital in an amount above the minimum risk-based capital requirements equal to 2.5% of total risk weighted assets, or face restrictions on the ability to pay dividends, pay discretionary bonuses, and to engage in share repurchases.

Under the FDIC’s prompt corrective action rules, which became effective January 1, 2015, an insured state nonmember bank is considered “well capitalized” if its capital ratios meet or exceed the ratios as set forth in the following table and is not subject to any written agreement, order, capital directive, or prompt corrective action directive to meet and maintain a specific capital level for any capital measure.  The Bank must meet well capitalized requirements under prompt corrective action provisions.  Prompt corrective action provisions are not applicable to bank holding companies.

A bank holding company is considered “well capitalized” if the bank holding company (i) has a total risk-based capital ratio of at least 10.0%, (ii) has a Tier 1 risk-based capital ratio of at least 6.0%, and (iii) is not subject to any written agreement order, capital directive or prompt corrective action directive to meet and maintain a specific capital level for any capital measure.

At September 30, 2017, the capital levels of both the Company and the Bank exceeded all regulatory capital requirements and their regulatory capital ratios were above the minimum levels required to be considered well capitalized for regulatory purposes.  The capital levels of both the Company and the Bank at September 30, 2017 also exceeded the minimum capital requirements including the currently applicable capital conservation buffer of 1.25%.

The Company’s and the Bank’s actual regulatory capital ratios as of September 30, 2017 and December 31, 2016 are presented in the table below.

FAIR VALUE OF ASSETS AND LIABILITIES

FAIR VALUE OF ASSETS AND LIABILITIES

FAIR VALUE OF ASSETS AND LIABILITIES

14.FAIR VALUE OF ASSETS AND LIABILITIES

Determination of Fair Value

The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures.  The fair value of an asset or liability is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  Fair value is best determined based upon quoted market prices.  However, in many instances, there are no quoted market prices for the Company’s various assets or liabilities.  In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques.  Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.  Accordingly, the fair value estimates may not be realized in an immediate settlement of the asset or liability. 

The following methods and assumptions were used by the Company in estimating fair value disclosures:

Cash and cash equivalents - The carrying amounts of cash and short-term instruments approximate fair values based on the short-term nature of the assets.

Securities - All fair value measurements are obtained from a third-party pricing service and are not adjusted by management.  Securities measured at fair value in Level 1 are based on quoted market prices in an active exchange market.  Securities measured at fair value in Level 2 are based on pricing models that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes, credit spreads and new issue data. 

FHLB stock - The fair value of Federal Home Loan Bank stock is equal to cost based on redemption provisions.

Loans held for sale - Fair values are based on prevailing market prices for similar commitments.  At September 30, 2017 and December 31, 2016, there were no loans held for sale that were greater than ninety days past due. 

The following table provides the fair value and contractual principal balance outstanding of loans held for sale accounted for under the fair value option:

	September 30,		December 31,
	2017		2016
	(in thousands)
Loans held for sale, fair value	$	96,201	$	86,443
Loans held for sale, contractual principal outstanding		92,981		85,024
Fair value less unpaid principal	$	3,220	$	1,419

Loans - Fair values for mortgage loans and other loans are estimated using discounted cash flow analyses, using market interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.  Fair values for non-performing loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable.

Retirement plan annuities - The carrying value of the annuities are based on their contract values which approximate fair value.

Mortgage servicing rights - Fair value is based on a third party valuation model that calculates the present value of estimated future net servicing income and includes observable market data such as prepayment speeds and default and loss rates.

Deposits and mortgagors’ escrow accounts - The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and certain types of money market accounts) and mortgagors’ escrow accounts are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts).  Fair values for certificates of deposit are estimated using a discounted cash flow calculation that applies market interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Borrowed funds - The fair values of borrowed funds are estimated using discounted cash flow analyses based on the current incremental borrowing rates in the market for similar types of borrowing arrangements.

Accrued interest - The carrying amounts of accrued interest approximate fair value.

Forward loan sale commitments and derivative loan commitments - Forward loan sale commitments and derivative loan commitments are based on fair values of the underlying mortgage loans and the probability of such commitments being exercised.  The assumptions for pull-through rates are derived from internal data and adjusted using management judgment. Derivative loan commitments include the value of servicing rights and non-refundable costs of originating the loan based on the Company’s internal cost analysis that is not observable.   At September 30, 2017 and December 31, 2016, the weighted average pull-through rate for derivative loan commitments was 87% and 86%, respectively.  

Interest rate swaps and risk participation agreements - The Company’s interest rate swaps are traded in over-the-counter markets where quoted market prices are not readily available.  For these interest rate derivatives, fair value is determined by a third party utilizing models that use primarily market observable inputs, such as swap rates and yield curves.  The pricing models used to value interest rate swaps calculate the sum of each instrument’s fixed and variable cash flows, which are then discounted using an appropriate yield curve to arrive at the fair value of each swap.  The pricing models do not contain a high level of subjectivity as the methodologies used do not require significant judgment.  The Company incorporates credit valuation analysis for counterparty nonperformance risk in the fair value measurement, including the impact of netting applicable credit enhancements such as available collateral.

Off-balance sheet credit-related instruments - Fair values for off-balance sheet, credit related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing.  The fair value of off-balance sheet instruments are immaterial.

Fair Value Hierarchy

The Company groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value.

Level 1 – Valuation is based on quoted prices in active markets for identical assets or liabilities.  Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.

Level 2 – Valuation is based on observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. 

Level 3 – Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.  Level 3 assets and liabilities include assets and liabilities whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as assets and liabilities for which the determination of fair value requires significant management judgment or estimation. 

Transfers between levels are recognized at the end of the reporting period, if applicable.  There were no transfers during the periods presented.

Assets Measured at Fair Value on a Non-recurring Basis

The Company may also be required, from time to time, to measure certain other financial assets on a nonrecurring basis in accordance with generally accepted accounting principles.  These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets.  There were no liabilities measured at fair value on a non-recurring basis at September 30, 2017 and December 31, 2016.  The following table summarizes the fair value hierarchy used to determine each adjustment and the carrying value of the related individual assets.

Losses applicable to write-downs of impaired loans and other real estate owned and repossessed assets are based on the appraised value of the underlying collateral less estimated costs to sell.  The losses on impaired loans are not recorded directly as an adjustment to current earnings, but rather as a component in determining the allowance for loan losses.  The losses on other real estate owned and repossessed assets represent adjustments in valuation recorded during the time period indicated and not for losses incurred on sales.  Appraised values are typically based on a blend of (a) an income approach using observable cash flows to measure fair value, and (b) a market approach using observable market comparables.  These appraised values may be discounted based on management’s historical knowledge, expertise or changes in market conditions from time of valuation.

Summary of Fair Values of Financial Instruments

The estimated fair values, and related carrying or notional amounts, of the Company’s financial instruments are as follows.  Certain financial instruments and all nonfinancial instruments are exempt from disclosure requirements.  Accordingly, the aggregate fair value amounts presented herein may not necessarily represent the underlying fair value of the Company.

SEGMENT REPORTING

SEGMENT REPORTING

16.SEGMENT REPORTING

The Company has two reportable segments: HarborOne Bank and Merrimack Mortgage.  Revenue from HarborOne Bank consists primarily of interest earned on loans and investment securities and service charges on deposit accounts.  Revenue from Merrimack Mortgage comprises interest earned on loans and fees received as a result of the residential mortgage origination, sale and servicing process. 

The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies.  Segment profit and loss is measured by net income on a legal entity basis.  Intercompany transactions are eliminated in consolidation.

Information about the reportable segments and reconciliation to the unaudited interim Consolidated Financial Statements at September 30, 2017 and 2016 and for the three and nine months then ended is presented in the tables below.  Merrimack Mortgage was acquired in July 2015.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Bais of Presentation and Consolidation

Basis of Presentation and Consolidation

The unaudited interim Consolidated Financial Statements of HarborOne Bancorp, Inc. (the “Company”) presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by the U.S. generally accepted accounting principles (“GAAP”).  In the opinion of management, all adjustments and disclosures considered necessary for the fair presentation of the accompanying Consolidated Financial Statements have been included.  Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2016 and 2015 and notes thereto included in the Company’s Annual Report on Form 10-K.

The unaudited interim Consolidated Financial Statements include the accounts of the Company, the Company’s subsidiaries Legion Parkway Company LLC, a security corporation formed on July 13, 2016 and HarborOne Bank (the “Bank”); and the Bank’s wholly-owned subsidiaries.  The Bank’s subsidiaries consist of a mortgage company and two security corporations.  Merrimack Mortgage Company, LLC (“Merrimack Mortgage”) was acquired and became a wholly-owned subsidiary of the Bank on July 1, 2015.  The security corporations were established for the purpose of buying, holding and selling securities on their own behalf.  All significant intercompany balances and transactions have been eliminated in consolidation.

Stock Conversion

Stock Conversion

On June 29, 2016, the Bank reorganized into a two-tier mutual holding company structure with a mid-tier stock holding company. The Company sold 14,454,396 shares of common stock at $10.00 per share, including 1,187,188 shares purchased by the Company’s Employee Stock Ownership Plan (“ESOP”). In addition, the Company issued 17,281,034 shares to HarborOne Mutual Bancshares, a mutual holding company (the “MHC”) and 385,450 shares to The HarborOne Foundation,a charitable foundation formed in connection with the stock offering and dedicated to supporting charitable organizations operating in the Bank’s local community. A total of 32,120,880 shares of common stock were outstanding following the completion of the stock offering. The direct costs of the Company’s stock offering of $3.9 million were deferred and deducted from the proceeds of the offering. 

Upon the completion of the stock offering, a special “liquidation account” was established for the benefit of certain depositors of the Bank in an amount equal to the percentage ownership interest in the equity of the Company held by persons other than the MHC as of the date of the latest balance sheet contained in the prospectus. The Company is not permitted to pay dividends on its capital stock if the Company’s shareholders’ equity would be reduced below the amount of the liquidation account. The liquidation account will be reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases in an eligible account holder’s qualifying deposits will not restore such holder’s interest in the liquidation account.

Nature of Operations

Nature of Operations

The Company provides a variety of financial services to individuals and businesses through its fourteen full-service and two limited-service bank offices in eastern Massachusetts, a commercial lending office in Providence, Rhode Island, and a loan office in Westford, Massachusetts.  Merrimack Mortgage maintains 33 offices in Massachusetts, New Hampshire, and Maine, and is also licensed to lend in seven additional states. 

The Company’s primary deposit products are checking, money market, savings and term certificate of deposit accounts while its primary lending products are commercial real estate, commercial, residential mortgages and consumer loans, including indirect automobile lending. The Company also originates, sells and services residential mortgage loans primarily through Merrimack Mortgage.

Use of Estimates

Use of Estimates

In preparing unaudited interim Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuations of mortgage servicing rights, derivatives, goodwill and deferred tax assets. 

Allowance for Loan Losses

Allowance for Loan Losses

The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings.  Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed and generally do not exceed the time frame provided in the FDIC’s Uniform Retail Credit Classification and Account Management Policy.  Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a regular basis by management.  This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.  The allowance consists of general, allocated and unallocated components, as further described below.

General component

The general component of the allowance for loan losses is based on historical loss experience adjusted for qualitative factors stratified by the Company’s loan segments.  Management uses arolling average of historical losses based on a time frame appropriate to capture relevant loss data for each loan segment except commercial real estate and commercial loans.  Due to the lack of historical loss experience for our commercial real estate and commercial loan portfolio, we utilize peer loss data.  Adjustments to this historical loss factor are considered for the following qualitative factors: levels/trends in delinquencies; trends in volume and terms of loans; effects of changes in risk selection and underwriting standards and other changes in lending policies, procedures and practices; experience/ability/depth of lending management and staff; and national and local economic trends and conditions.  There were no changes in the Company’s policies or methodology pertaining to the general component of the allowance for loan losses during 2016 or the nine months ended September 30, 2017.  The qualitative factors are determined based on the various risk characteristics of each loan segment.  Risk characteristics relevant to each portfolio segment are as follows:

Residential real estate – The Company generally does not originate portfolio loans with a loan-to-value ratio greater than 80 percent without obtaining private mortgage insurance and does not generally grant loans that would be classified as subprime upon origination.  The Company generally has first or second liens on property securing equity lines of credit.  Loans in this segment are generally collateralized by residential real estate and repayment is dependent on the credit quality of the individual borrower.  The overall health of the economy, including unemployment rates and housing prices, can have an effect on the credit quality in this segment.  

Commercial real estate – Loans in this segment are primarily secured by income-producing properties in southeastern New England.  The underlying cash flows generated by the properties can be adversely impacted by a downturn in the economy as evidenced by increased vacancy rates, which in turn, could have an effect on the credit quality in this segment.  Management obtains rent rolls annually and continually monitors the cash flows of these loans.

Construction – Loans in this segment include both residential and commercial construction loans.  Residential construction loans include loans to build one- to four-family owner-occupied properties, which are subject to the same credit quality factors as residential real estate loans.  Commercial construction loans may include speculative real estate development loans for which payment is derived from lease or sale of the property.  Credit risk is affected by cost overruns, time to lease or sell at an adequate price, and market conditions.

Commercial – Loans in this segment are made to businesses and are generally secured by assets of the business.  Repayment is expected from the cash flows of the business.  A weakened economy, and resultant decreased consumer or business spending, could have an effect on the credit quality in this segment.  

Consumer – Loans in this segment are generally secured by automobiles or unsecured and repayment is dependent on the credit quality of the individual borrower.

Allocated component

The allocated component relates to loans that are classified as impaired.  Residential real estate, commercial, commercial real estate and construction loans are evaluated for impairment on a loan-by-loan basis.  Impairment is determined by nonaccrual status, whether a loan is subject to a troubled debt restructuring agreement or in the case of certain loans, based on the internal credit rating.  Large groups of smaller balance homogeneous loans are collectively evaluated for impairment.  Accordingly, except for troubled debt restructuring (“TDR”), the Company does not separately identify individual consumer loans for impairment evaluation. 

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement.  Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due.  Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired.  Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. 

The Company periodically may agree to modify the contractual terms of loans.  When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a TDR.  All TDRs are initially classified as impaired.  Impairment is measured by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent.  An allowance is established when the discounted cash flows or collateral value of the impaired loan is lower than the carrying value of that loan.

Unallocated component

The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating allocated and general reserves in the portfolio. The unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. Additionally the Company's unseasoned commercial portfolio and use of peer group data to establish general reserves for the commercial portfolio adds another element of risk to management's estimates.

Stock-based Compensation Plans

Stock-based Compensation Plans

The Company’s stock-based compensation plans provide for awards of stock options, restricted stock and other stock-based compensation to directors, officers and employees.  The cost of employee services received in exchange for awards of equity instruments is based on the grant-date fair value of those awards.  Compensation cost is recognized over the requisite service period as a component of compensation expense.  The Company uses the Black-Scholes option-pricing model to determine the fair value of stock options granted, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. The Company has elected to early adopt Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.Under this Update, the Company has elected to account for forfeitures of share-based payments by recognizing forfeitures of awards as they occur (e.g., when an award does not vest because the employee leaves the Company or does not meet specific performance measures).

Earnings Per Share

Earnings Per Share

Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period.  Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. The restricted stock awards are participating securities; therefore unvested awards are included as common shares outstanding in the computation of basic earnings per share. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate to outstanding stock options awards and are determined using the treasury stock method.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

As an “emerging growth company” as defined in Title 1 of the Jumpstart Our Business Startups (JOBS) Act, the Company has elected to use the extended transition period to delay the adoption of new or reissued accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies.  As of September 30, 2017, there is no significant difference in the comparability of the financial statements as a result of this extended transition period.

In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. This guidance changes the recognition and presentation requirements of hedge accounting, including eliminating the requirement to separately measure and report hedge ineffectiveness and presenting all items that affect earnings in the same income statement line as the hedged item. This guidance also provides new alternatives for applying hedge accounting to additional hedging strategies, measuring the hedged item in fair value hedges of interest rate risk, reducing the complexity of applying hedge accounting by easing the requirements for effectiveness testing, hedge documentation and application of the critical terms match method, and reducing the risk of material error corrections if a company applies the shortcut method inappropriately.  This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company does not have any derivatives within the scope of the ASU.

In March 2017, the FASB issued ASU 2017-08, Receivables- Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The Company elected to early adopt this new accounting guidance effective January 1, 2017 and the adoption did not have a material impact on the Consolidated Financial Statements.

In January 2017, FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.  This update changes the quantitative impairment test to require an entity to perform a one-step test and record the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value, not to exceed the amount of goodwill allocated to the reporting unit.  This new guidance does not amend the optional qualitative assessment of goodwill impairment.  For SEC filers, the ASU is effective for impairment tests in fiscal years beginning after December 15, 2019.  For non-public business entities, the ASU is effective for impairment tests in fiscal years beginning after December 15, 2021.  Early adoption is permitted for impairment tests performed on testing dates after January 1, 2017.  The Company elected to early adopt this new accounting guidance effective October 1, 2017 and the adoption did not have an impact on the Consolidated Financial Statements.

In June 2016, FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), which requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts.  Entities will now use forward-looking information to better form their credit loss estimates.  The ASU also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio.  For public entities that are SEC filers, this ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.  For non-public entities, this ASU is effective for fiscal years beginning after December 15, 2020, and for interim periods within fiscal years beginning after December 15, 2021.  Early application will be permitted for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018.  Management has identified an implementation team that is in the process of developing an understanding of this pronouncement, evaluating the impact of this pronouncement and researching additional software resources that could assist with the implementation.

In February 2016, FASB issued ASU 2016-02,  Leases (Topic 842).  This update requires a lessee to record a right-to-use asset and a liability representing the obligation to make lease payments for long-term leases.  For public business entities, this update is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  For non-public business entities, this update is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years beginning after December 15, 2020.  While we are currently evaluating the impact of the new standard, we expect an increase to the Consolidated Balance Sheets for right-of-use assets and associated lease liabilities but no material impact to the Consolidated Statement of Operations, for arrangements previously accounted for as operating leases.

In January 2016, FASB issued ASU 2016-01, Financial Instruments – Overall, (Subtopic 825-10).  The amendments in this update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments.  Targeted improvements to generally accepted accounting principles include the requirement for equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, the elimination of the requirement for non-public business entities to disclose the fair value of financial instruments measured at amortized cost and the elimination of the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost.  For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years.  For non-public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019.  Management currently does not expect this to have a material impact on the Company's Consolidated Financial Statements as the Company does not currently hold any equity securities.

In May 2014, FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The amendments in this update create Topic 606, Revenue from Contracts with Customers, and supersede the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve the core principle, a company should apply a five step approach to revenue recognition. For public business entities, this ASU is effective for annual reporting periods, including interim periods, beginning after December 15, 2017. For non-public business entities, this ASU is effective for annual reporting periods beginning after December 31, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early application is permitted, but only for annual reporting periods beginning after December 15, 2016. The Bank's primary source of revenue is interest income on financial assets and income from mortgage banking activities, which are explicitly excluded from the scope of the new guidance.  As a result, adoption is not expected to have a material impact on the Company’s Consolidated Financial Statements. However, the Company will continue to monitor developments and additional guidance up to the effective date of these amendments.
