(1)Summary of Significant Accounting Policies

(a) Organization of Holdingthe Company and Basis of Presentation

The accompanying unaudited consolidated interim financial statements and these notes should be read in conjunction with the December 31, 20162018 audited consolidated financial statements and notes thereto contained in the 20162018 Annual Report on Form 10-K of Enterprise Bancorp, Inc. as filed with the Securities and Exchange Commission (the "SEC") on March 13, 2019 (the "2018 Annual Report on Form 10-K"). 

The accompanying unaudited consolidated interim financial statements of Enterprise Bancorp, Inc. (the "Company," "Enterprise," "we," or "our"), a Massachusetts corporation, as filed with the Securities and Exchange Commission (the "SEC") on March 14, 2017 (the "2016 Annual Report on Form 10-K").  The Company has not changed its accounting policies from those disclosed in its 2016 Annual Report on Form 10-K.

The Company's unaudited consolidated interim financial statements include the accounts of the Company and its wholly owned subsidiary, Enterprise Bank and Trust Company, commonly referred to as Enterprise Bank (the "Bank").  The Bank is a Massachusetts trust company and state chartered commercial bank organized in 1989. Substantially all of the Company's operations are conducted through the Bank and its subsidiaries. The Company has not materially changed its accounting policies from those disclosed in its 2018 Annual Report on Form 10-K. See Item (f) "Recent Accounting Pronouncements" under the subheading "Accounting pronouncements adopted by the Company" below in this Note 1.

The Bank's subsidiaries include Enterprise Insurance Services, LLC and Enterprise InvestmentWealth Services, LLC, both organized under the laws of the State of Delaware, for the purposes of engagingengage in insurance sales activities and offeringoffer non-deposit investment products and services, respectively.  In addition, the Bank has the following subsidiaries that are incorporated in the Commonwealth of Massachusetts and classified as security corporations in accordance with applicable Massachusetts General Laws: Enterprise Security Corporation; Enterprise Security Corporation II; and Enterprise Security Corporation III.  The security corporations, which hold various types of qualifying securities, are limited to conducting securities investment activities that the Bank itself would be allowed to conduct under applicable laws.

The Company's headquarters and the Bank's main office are located at 222 Merrimack Street in Lowell, Massachusetts. At September 30, 2017,March 31, 2019, the Company had 24 full service branchesbranch banking offices serving the Greater Merrimack Valley, Nashoba Valley and North Central regions of Massachusetts and Southern New Hampshire (Southern Hillsborough and Rockingham counties). Through the Bank and its subsidiaries, the Company offers a range of commercial, residential and consumer loan products, deposit products and cash management services, as well as investment advisoryelectronic and digital banking options, and insurance services.  The Company also provides a range of wealth management, wealth services and trust services delivered via two channels, Enterprise Wealth Management and insurance services.Enterprise Wealth Services. The services offered through the Bank and its subsidiaries are managed as one strategic unit and represent the Company's only reportable operating segment.

The Federal Deposit Insurance Corporation (the "FDIC") and the Massachusetts Division of Banks (the "Division") have regulatory authority over the Bank.  The Bank is also subject to certain regulatory requirements of the Board of Governors of the Federal Reserve System (the "Federal Reserve Board") and, with respect to its New Hampshire branch operations, the New Hampshire Banking Department.  The business and operations of the Company are subject to the regulatory oversight of the Federal Reserve Board.  The Division also retains supervisory jurisdiction over the Company.

The accompanying unaudited consolidated interim financial statements and notes thereto have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and the instructions for SEC Form 10-Q through the rules and interpretive releases of the SEC under federal securities law. In the opinion of management, the accompanying unaudited consolidated interim financial statements reflect all necessary adjustments consisting of normal recurring accruals for a fair presentation.  All significant intercompany balances and transactions have been eliminated in the accompanying unaudited consolidated interim financial statements. Certain previous years' amounts in the audited consolidated financial statements, and notes thereto, have been reclassified to conform to the current year's presentation. Interim results are not necessarily indicative of results to be expected for the entire year, or any future period.

The Company has evaluated subsequent events and transactions from September 30, 2017March 31, 2019 through the date this Quarterly Report on Form 10-Q (this "Form 10-Q") was filed with the SEC for potential recognition or disclosure as required by GAAP and determined that there were no material subsequent events requiring recognition or disclosure.

(b) Critical AccountingUses of Estimates

In preparing the unaudited consolidated interim financial statements in conformity with GAAP, management is required to exercise judgment in determining many of the methodologies, assumptions and estimates to be utilized.  These assumptions and estimates affect the reported values of assets and liabilities as of the balance sheet datedates and income and expenses for the period then ended.  As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates should the assumptions and estimates used be incorrect or change over time due to changes in


8

ENTERPRISE BANCORP, INC.
Notes to the Unaudited Consolidated Interim Financial Statements

circumstances.  Changes in those estimates resulting from continuing changechanges in the economic environment and other factors will be reflected in the consolidated financial statements and results of operations in future periods.

As discussed in the Company's 20162018 Annual Report on Form 10-K, the three most significant areas in which management applies critical assumptions and estimates areare: the estimates of the allowance for loan losses, impairment review of investment securities, and the impairment review of goodwill.  Refer to Note 1, "Summary of Significant Accounting Policies," to the Company's audited consolidated financial statements included in the Company's 20162018 Annual Report on Form 10-K for accounting policies related to these significant estimates. The Company has not changed its significant accounting policies from those disclosed in its 20162018 Annual Report on Form 10-K.

(c) Restricted InstrumentsCash and Investments

Certain of the Company's derivative agreements contain provisions that require the Companyfor collateral to post collateralbe posted if the derivative exposure exceeds a threshold amount. When the Company has pledged cash as collateral for this purpose, the cash is carried as restricted cash within "Interest-earning Deposits." See Note 8, "Derivatives and Hedging Activities," to the Company's unaudited consolidated interim financial statements below for more information about the Company's collateral related to its derivatives.

The Bank is also required by the Federal Reserve Bank of Boston ("FRB") to maintain in reserves certain amounts of vault cash and/or deposits with the FRB. The average daily cash balance on hand for reserve requirements included in "Cash and cash equivalents.Due from Banks" was approximately $2.9 million, based on the two-week computation period encompassing March 31, 2019.

As a member of the Federal Home Loan Bank of Boston ("FHLB"),FHLB, the Company is required to purchase certain levels of FHLB capital stock at par value in association with outstanding advances from the FHLB.  From time-to-time, the FHLB may initiate the repurchase, at par value, of "excess" levels of its capital stock held by member banks. This stock is classified as a restricted investment and is carried at cost, which management believes approximates fair value.  FHLB stock represents the only restricted investment held by the Company.
 
Management regularly reviews its holdings of FHLB stock for other-than-temporary-impairment ("OTTI"). Based on management's periodic review, the Company has not recorded any OTTI charges on this investment to date. If it was determined that a write-down of FHLB stock was required, impairment would be recognized through a charge to earnings.

See Note 2, "Investment Securities," to the Company's unaudited consolidated interim financial statements below for additional information on management's OTTI review.

(d) Revenue Recognition-Accounting Standard Codification ("ASC") Topic 606

While the majority of the Company's revenue is generated from contracts with customers, our primary sources of revenue, interest and dividend income (primarily loan interest income), are outside of the scope of ASC 606, "Revenue from Contracts with Customers-Topic 606," and are accounted for under other ASC topics. The core principles of this standard require an entity to recognize revenue to depict the transfer of goods and services to customers as performance obligations are satisfied.

The primary areas of income within the scope of ASC 606, which are also the first two lines of non-interest income on the Company's consolidated statements of income, are discussed below.

Wealth management fees consist of income generated through Enterprise Wealth Management and Enterprise Wealth Services. Enterprise Wealth Management income is primarily generated by managing customers' financial assets. Revenue is recognized as our performance obligation is completed each month. Enterprise Wealth Services revenue is generated through a third-party arrangement to refer, manage and service customers. For new sales and referrals along with transactional type charges, the performance obligation is based on a point in time and the payment is received and revenue is recognized in the


9

ENTERPRISE BANCORP, INC.
Notes to the Unaudited Consolidated Interim Financial Statements

same month as the revenue-generating activity. For managing and servicing customers, revenue is recognized when our performance obligation is completed each month.

Deposit and interchange fees are comprised of deposit account related charges and income generated from electronic payment interchanges. Deposit account charges consist of certain transactional analysis fees net of earning balance credits, monthly account service fees, and transactional fees such as overdraft fees. Analysis and monthly services fees are recognized over the period the service is performed. For transactional fees, the performance obligation and the revenue are recognized at a point of time and payment is typically received as the service is rendered. Interchange income is generated primarily from retail debit card transactions processed through the card payment network. The performance obligation and the revenue are recognized when the service is performed.

The following non-interest income components are not subject to ASC 606: income on bank-owned life insurance ("BOLI"), net gains/losses on sales of investment securities, and net gains on sales of loans, and are covered under other ASC topics. The remaining revenue items in non-interest income are not material.

See also Note 1, "Summary of Significant Accounting Policies," to the Company's audited consolidated financial statements in the Company's 2018 Annual Report on Form 10-K for additional accounting policies on revenue recognition related to income generated on investments, gains and losses on debt security sales, net gains on loans held for sale, and loans.

(e) Income Taxes
 
The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and in the states of Massachusetts and New Hampshire within the directives of the respective enacted tax legislation. The Company uses the asset and liability method of accounting for income taxes.  Under this method, deferred tax assets and liabilities are recognized for the future tax expense or benefit attributable to differences between the financial statement carrying amounts and the tax basis of assets and liabilities.  The deferred tax assets and liabilities are reflected at currently enactedcurrently-enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled.  As changes in tax laws or rates are enacted, deferred tax assets and liabilities will be adjusted accordingly through the provision for income taxes in the period that includes the enactment date.

The Company's policy is to classify interest resulting from underpayment of income taxes as income tax expense in the first period the interest would begin accruing according to the provisions of the relevant tax law.  The Company classifies penalties resulting from underpayment of income taxes as income tax expense in the period for which the Company claims or expects to claim an uncertain tax position or in the period in which the Company's judgment changes regarding an uncertain tax position.
 
The income tax provisions will differ from the expense that would result from applying the federal statutory rate to income before taxes, due primarily to the impact of state tax expense, tax-exempt interest from certain investment securities, loans and bank-owned life insurance.BOLI and tax benefits from equity compensation deductions.

The Company did not have any unrecognized tax benefits accrued as income tax liabilities or receivables or as deferred tax items at September 30, 2017March 31, 2019.  The Company is subject to U.S. federal and state income tax examinations by taxing authorities for the 20132015 through 20162018 tax years.

(e)(f) Recent Accounting Pronouncements

Accounting pronouncements adopted by the Company

In MarchFebruary 2016, the Financial Accounting Standards Board (the "FASB"("FASB") issued Accounting Standards Update ("ASU" or "Update") No. 2016-09, "Compensation - Stock Compensation2016-02, "Leases (Topic 718): Improvement to Employee Share-Based Payment Accounting.842)," which supersedes previous leasing guidance in Topic 840. Under the new guidance, as amended, lessees are required to recognize lease (right-of-use or "ROU") assets and lease liabilities on the balance sheet for all leases with terms longer than 12 months. The Company adopted and is applying the new lease standard was effective for fiscal years beginningon leases existing on or after December 15, 2016, including interim periods within those fiscal years.January 1, 2019.

The Company adopted ASU No. 2016-09 in the first quarter of 2017. Several aspects of the accounting are simplified including, generally: a) income tax consequences; b) classification of awards as either equity or liabilities; c) accounting for forfeitures; and d) classification on the statement of cash flows. Upon adoption, the most significant impact of this amendment resulted from the prospective application of current excess tax benefits and deficiencies being recognized in income tax expense, which would previously have been recognized in additional paid-in capital, in the reporting period in which they occur. For the nine months ended September 30, 2017,Company, this reduced the Company's provision for income taxes, increasing earnings by approximately $832 thousand. For the year ended December 31, 2016, the Company recognized $789 thousand in additional paid-in-capital in this regard, which, if under the new ASU would have been recognized as income tax benefit in the income statement. This amount, treated as discrete items in the period in which they occur, will vary from year to yearprimarily impacted operating leases on our facilities, mainly branch leases, and as a function of the volume of share-based payments vested or exercised and the then current market price of the Company's stock in comparison to the compensation cost recognized in the consolidated financial statements.

Additionally upon adoption, the Company made a policy election to record forfeitures as they occur rather than make use of an estimate. Using a modified retrospective approach,result the Company recorded, an immaterial cumulative effect adjustment from retained earningson its consolidated balance sheet a lease liability of $18.0 million and ROU asset of $19.0 million on January 1, 2019 related to additional paid-in-capital.these leases. The other provisions did not have a material impact onlease liability represents the Company's consolidated financial statements upon adoption.

Accounting pronouncements not yet adopted by the Company (in order of effective date of implementation)

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." This ASU is intended to create a single source of revenue guidance which is more principles based than current revenue guidance. The guidance affects any entity that either enters into contracts with customers to transfer goods or services, or enters into contracts for the transfer of non-financial assets, unless those contracts are within the scope of other standards. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferralpresent value of the Effective Date" to amendfuture lease payments. The ROU asset includes the effective date of ASU 2014-09. The amendments in ASU 2014-09 are effective for annuallease liability, lease prepayments and interim periods within fiscal years beginning after December 15, 2017. Earlier adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The FASB has since issued additional related ASUs amendments intended to clarify certain aspects and improve understanding of the implementation guidance of Topic 606 but do not change the core principles of the guidance in Topic 606. The effective date and transition requirements for the amendments are the same as the effective date and transition requirements of Topic 606.

The Company is currently evaluating the potential impact of the ASU and its amendments on the Company's consolidated financial statements, results of operations, and disclosures and does not currently plan to early adopt. Based on the Company's initial review, and because the largest portion of the Company's revenue, interest income and various loan fees, are specifically excluded from the scope of this ASU, and because the Company currently recognizes the majority of the remaining revenue sources in a manner that management believes is consistent with the new ASU, management believes that this new standard will not materially impact the Company's consolidated financial statements, results of operations or disclosures. The foregoing observations are subject to change as management completes their evaluation.

In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments.

Among other things, the new guidance:
Requires 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;indirect costs, less accrued lease liabilities.


10

ENTERPRISE BANCORP, INC.
Notes to the Unaudited Consolidated Interim Financial Statements
 

Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; and
Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) on the balance sheet or the accompanying notesSee Note 5, "Leases," to the Company's unaudited consolidated interim financial statements.

The new guidance is effectivestatements, contained below, for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years.

The Company is currently evaluatingfurther information regarding the effects of this ASUCompany's operating leases and associated expenses which are included in occupancy and equipment expenses on the Company's consolidated financial statements, resultsstatement of operations and disclosures. Based on the Company's evaluation to date, management believes the more significant implications upon adoption of this ASU will be the potential recognition of changes in fair value of the Company's equity portfolio in net income. Under current GAAP, net unrealized appreciation or depreciation on the equity portfolio, net of applicable income taxes, are reflected as a component of accumulated other comprehensive income. The net unrealized gain or loss on equity securities will fluctuate based on changes in the market value of the mutual funds and individual securities held in the portfolio.  For the nine months ended September 30, 2017, other comprehensive losses, net of taxes, generated from the equity portfolio amounted to $670 thousand, compared to a gain of $178 thousand generated for the nine months ended September 30, 2016. Any potential future changes in fair value of the equity portfolio recognized in net income will depend on the amount of dollars invested in the portfolio and the potential magnitude of changes in equity market values. The foregoing observations are subject to change as management completes their evaluation.

In August 2016,2017, the FASB issued ASU No. 2016-15, "Statement2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." The objective of Cash flows (Topic 230) - Classificationthe ASU is to better align hedge accounting with an organization's risk management activities in the financial statements. In addition, the ASU simplifies the application of Certain Cash Receipts and Cash Payments."hedge accounting guidance in areas where practice issues exist. The amendments expand the strategies that qualify for hedge accounting, change how many hedging relationships are intended to reduce diversitypresented in practice related to the presentationfinancial statements and simplify the application of eight specifichedge accounting in certain situations, reducing the operational complexities associated with certain existing strategies. New or modified disclosures are required, primarily for fair value and cash flow issues.hedges. For public business entities, that are SEC filers, such as the Company, the amendments in this Update areASU was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Because this amendment primarily impacts the presentation2018, and classification of information, the Company does not expect this ASU to have an impact on the Company's consolidated financial statements and results of operations.

In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash flows-Restricted Cash (Topic 230)." The amendments in this Update clarify the inclusion of restricted cash in the cash and cash equivalents beginning-of-period and end-of period reconciliation on the statement of cash flows. For public business entities that are SEC filers, such as the Company, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Because this amendment primarily impacts the presentation and classification of information, the Company does not expect this ASU to have an impact on the Company's consolidated financial statements and results of operations.

In March 2017, the FASB issued ASU No. 2017-07, "Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The amendments in this Update outline the presentation, classification and disclosure requirements for service cost and other components of net benefit costs. For public business entities that are SEC filers, such as the Company, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. Because this amendment primarily impacts the presentation and classification of information, the Company does not expect this ASU to have an impact on the Company's consolidated financial statements and results of operations.

In May 2017, the FASB issued ASU No. 2017-09, "Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting." The amendments in this Update apply to entities that change the terms of an outstanding share-based payment award. The amendments are intended to reduce diversity in practice as well as cost and complexity when applying guidance in Topic 718 to the modification of the terms and conditions of a share-based payment award. This ASU provides guidance on the three modifications to share-based payment awards and conditions that must be met in order to exempt an entity from modification accounting under topic 718. The amendments in this Update apply prospectively to award modifications on or after the adoption date, and are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company currently does not expecthold any instruments that meet hedge accounting requirements and therefore the adoption of thethis ASU, willin January 2019, did not have a materialan impact on itsthe Company's unaudited consolidated interim financial statements, results of operations or disclosures.disclosures, however, the Company may utilize hedging strategies in the future.

In February 2016,June 2018, the FASB issued ASU No. 2016-02, "Leases2018-07, "Compensation-Stock-Based Compensation (Topic 842),718): Improvements to Nonemployee Shared-Based Payment Accounting." The amendments in the ASU expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees except for share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract. Additionally, Topic 718 has been updated for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which supersedes previous leasing guidance in Topic 840, Leases.

The Company is currently evaluatingperiod in which the effects of this ASU on the Company's consolidated financial statements, results of operations and disclosures. Based on the Company's evaluation to date, management believes the more significant implication of this ASU on the Company relates to operating leases of our facilities, mainly branch leases. As of September 30, 2017, the Company had leases on 17 of its locations, including branches and part of its main campus, and expects that uponservices are rendered. The adoption of this ASU the balance sheet will reflect both lease liabilities, equal to the present value of lease payments, and right-of-use assets, equal to the lease liability plus payments made to lessors adjusted for prepaid or accrued rent and any initial direct cost incurred. In addition, the Company will recognize lease expensestandard in the income statement on a straight-line basis similar to current operating leases. The straight-line expense will reflect the interest expense on the lease liability (effective interest method) and amortization of the right-of-use asset. Lease expense will be presented as a single line item in the operating expense section of the income statement. Management believes that lease expense under the new standard will generally approximate lease expense under current GAAP. The foregoing observations are subject to change as management completes their evaluation.

In March 2017, the FASB issued ASU No. 2017-08, "Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." The amendments shorten the amortization period to the earliest call date for certain callable debt securities held at a premium. The accretion for securities held at a discount isJanuary 2019 did not affected by this statement and remains unchanged. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective basis is required upon adoption. Early adoption is permitted. The Company has assessed the impact of this ASU and does not expect that it will have a material impact on the Company's unaudited consolidated interim financial statements, results of operations and disclosures upon adoption.or disclosures.

Accounting pronouncements not yet adopted by the Company (in order of effective date of implementation)

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The amendments in this ASU require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. Previously, when credit losses were measured under GAAP, an entity generally only considered past events and current conditions in measuring the incurred loss and generally recognition of the full amount of credit losses was delayed until the loss was probable of occurring. The amendments in this ASU eliminate the probable initial recognition threshold in current GAAP and, instead, reflect an entity’sentity's current estimate of all expected credit losses.losses (commonly known as "CECL").

The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset.

Credit losses on available-for-sale debt securities should be measured in a manner similar to current GAAP. However, the amendments in this UpdateASU require that credit losses be presented as an allowance rather than as a write-down. Unlike current GAAP, the ASU provides for reversals of credit losses in future period net income in situations where the estimate of loss declines.

An entity will apply the amendments in this UpdateASU through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). For public business entities that are SEC filers, such as the Company, the amendments in this UpdateASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption for fiscal years beginning after December 15, 2018 is permitted.

The Company has established an implementation committee and an enterprise-wide implementation plan for this ASU, which will consider the impact to operations, financial results, disclosures and controls. At present, the impact of the adoption of ASU No. 2016-13 on the Company's operations, financial results, disclosures, and controls is unknown.

beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption for fiscal years beginning after December 15, 2018 is permitted.

In April 2018, banking regulators issued a proposed revision to their capital rules that addresses the regulatory capital treatment of credit loss allowances under the CECL methodology and, if enacted as proposed, would allow banking organizations to phase in the day-one regulatory capital effects of CECL adoption over three years.

The Company has established a project committee and an implementation plan for this ASU.  The impact of the adoption of ASU No. 2016-13 on the Company's operations, financial results, disclosures, and controls is under evaluation.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles-Goodwill and Other (Topic 350)-Simplifying the Test for Goodwill Impairment." The main provision in this ASU eliminated Step 2 of the goodwill impairment test and instead requires an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value of the reporting unit with its carrying amount. An impairment charge would be recognized for the amount the carrying value exceeds the reporting unit's fair value as long as the amount recognized doesn'tdoes not exceed the amount of goodwill allocated to the reporting unit. For public business entities that are SEC filers, such as the Company, the amendments in this UpdateASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for impairment tests performed on testing dates after January 1, 2017. Goodwill carried on the Company’sCompany's consolidated financial statements was $5.7 million at both September 30, 2017March 31, 2019 and December 31, 2016.2018. This asset is related to the Company’s acquisition of two branch offices in July 2000. The Company does not expect the adoption of ASU No. 2017-012017-04 to have a material impact on the Company's consolidated financial statements and results of operations.

In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement (Topic 820-Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement." The amendments in this ASU modify the disclosure requirements primarily related to level 3 fair value measurements of the fair value hierarchy. This amendment is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. Because this ASU primarily relates to disclosure requirements, the Company does not expect the adoption of ASU No. 2018-13 to have a material impact on the Company's consolidated financial statements and results of operations.

In August 2018, the FASB issued ASU No. 2018-15, "Intangibles-Goodwill and Other- Internal-use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract." The major provision in the amendments in this ASU require an entity to capitalize certain implementation costs incurred in a hosting arrangement that is a service contract in accordance with current GAAP for internal-use software and expense these costs over the term of the hosting arrangement. Additionally, these capitalized implementation costs are required to be reviewed for impairment in accordance with current GAAP for internal-use software. This amendment is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company does not expect the adoption of ASU No. 2018-15 to have a material impact on the Company's consolidated financial statements and results of operations.

In August 2018, the FASB issued ASU No. 2018-14, "Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20) -Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans." The amendments in this ASU modify the disclosure requirements on defined benefit plans including requiring disclosures about significant gains and losses related to changes in the benefit obligation. This amendment is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. Because this ASU primarily relates to disclosure requirements and the balances of the benefit plans impacted by this ASU are immaterial to the Company, the adoption of ASU No. 2018-14 will not have a material impact on the Company's consolidated financial statements and results of operations.

Notes to the Unaudited Consolidated Interim Financial Statements

At September 30, 2017, the equity portfolio was comprised of investments Included in individual common stock of financial services entities.municipal securities were tax exempt municipal securities with fair values totaling $106.3 million and $107.3 million at March 31, 2019 and December 31, 2018, respectively.

As of the dates reflected in the tables above, all of the Company’s investmentCompany's debt securities were classified as available-for-sale and carried at fair value.

Net unrealized appreciation and depreciation on investmentsdebt securities available-for-sale, net of applicable income taxes, are reflected as a component of accumulated other comprehensive income (loss).

The net unrealized gain or loss in the Company's debt security portfolio fluctuates as market interest rates rise and fall.  Due to the predominantly fixed rate nature of this portfolio, as market rates fall, the value of the portfolio rises, and as market rates rise, the value of the portfolio declines.  The unrealized gains or losses on debt securities will also decline as the securities approach maturity. Unrealized gainslosses on debt securities that are deemed OTTI are generally charged to earnings, as described further in Note 1, "Summary of Significant Accounting Policies," under Item (e), "Investments," to the Company's audited consolidated financial statements contained in the Company's 2018 Annual Report on Form 10-K. Gains or losses will be recognized in the income statement if the securities are sold. However, if an unrealized loss on a debt security portfolio is deemed to be other than temporary, the credit loss portion is charged to earnings and the noncredit portion is recognized in accumulated other comprehensive income (loss).

The net unrealized gain or loss on equity securities will fluctuate based on changes in the market value of the mutual funds and individual securities held in the portfolio.  Unrealized gains or losses will be recognized in the statements of income if the securities are sold. However, if an unrealized loss on an equity security is deemed to be other than temporary prior to a sale, the loss is charged to earnings.

The Company did not hold any Certificates of deposit that had unrealized losses as of September 30, 2017.

During the three months ended March 31, 2019 and 2018, the Company did not record any fair value impairment charges (Other than temporary impairment or "OTTI") on its investments in debt securities. At March 31, 2019, management did not consider any debt securities to have OTTI. Management regularly reviews the portfolio for debt securities with unrealized losses that are other-than-temporarily impaired. There have been no material changes to the Company's process for assessing investments for OTTI as reported in the 2018 Annual Report on Form 10-K. For more information about the Company's assessment for OTTI, see Note 2, "Investment Securities," to the Company's audited consolidated financial statements contained in the Company's 2018 Annual Report on Form 10-K.

As noted in the table above, a small portion of the portfolio was invested in CDs and was also in an unrealized loss position at March 31, 2019 and December 31, 2018, due to market rates. The unrealized loss was not considered to be material and the securities are expected to mature at par value.

The contractual maturity distribution at March 31, 2019 of total debt securities was as follows:
(Dollars in thousands) Amortized Cost Fair Value
Due in one year or less $11,919
 $11,919

ENTERPRISE BANCORP, INC.
Notes to the Unaudited Consolidated Interim Financial Statements
 

During the nine months ended September 30, 2017 and 2016, the Company did not record any fair value impairment charges on its investments. Management regularly reviews the portfolio for securities with unrealized losses that are other-than-temporarily impaired. At September 30, 2017, management attributes the unrealized losses in the portfolio to increases in current market yields compared to the yields at the time the investments were purchased by the Company for debt securities and the impact of market value fluctuations on the equity portion of our portfolio. As of September 30, 2017, management did not consider its debt securities to be other-than-temporarily impaired because (1) the decline in market value is not attributable to a fundamental deterioration in quality of the securities or the issuers, and (2) the Company did not intend to sell, and it is more likely than not that it will not be required to, sell those investments prior to a market price recovery or maturity with recovery of the amortized cost. The unrealized losses in equity investments as of September 30, 2017 were not material.

In assessing the Company's investments in federal agency mortgage-backed securities and federal agency obligations, the contractual cash flows of these investments are guaranteed by the respective government sponsored enterprise (FHLMC, FNMA, FFCB, or FHLB) or wholly-owned government corporation (GNMA). Accordingly, it is expected that the securities would not be settled at a price less than the par value of the Company's investments. Management's assessment of other debt securities within the portfolio includes reviews of market pricing, ongoing credit quality evaluations, assessment of the investments' materiality, and duration of the investments' unrealized loss position. In addition, the Company utilizes an outside registered investment adviser to manage the corporate and municipal bond portfolios, within prescribed guidelines set by management, and to provide assistance in assessing the credit risk of those portfolios. At September 30, 2017, the Company's corporate and municipal bond portfolios did not contain any securities below investment grade, as reported by major credit rating agencies. For equities and funds, management's assessment includes the severity of the declines, whether it is unlikely that the security or fund will completely recover its unrealized loss within a reasonable time period and if the equity security or fund exhibits fundamental deterioration.

See "Financial Condition," in Item 2, "Management's Discussion and Analysis," under the heading "Investments" in this Form 10-Q for additional information about changes in the net unrealized gains (losses) on investments.

The contractual maturity distribution at September 30, 2017 of total debt securities was as follows:
(Dollars in thousands) Amortized Cost Fair Value
Due in one year or less $16,217
 $16,262
Due after one, but within five years 112,615
 113,439
Due after five, but within ten years 117,552
 118,680
Due after ten years 134,132
 134,515
Total debt securities $380,516
 $382,896

Scheduled contractual maturities shown above may not reflect the actual maturities of the investments. The actual MBS/CMO cash flows likely will be faster than presented above due to prepayments and amortization. Similarly, included in the fair value of debt securitiestable above are callable securities, comprised of municipal securities and corporate bonds, totaling $68.1with a fair value of $83.9 million, which can be redeemed by the issuerissuers prior to the maturity presented above.  Management considers these factors when evaluating the interest rateinterest-rate risk in the Company's asset-liability management program.

From time to time, the Company may pledge debt securities as collateral for deposit account balances of municipal customers, and for borrowing capacity with the FHLB and the Federal Reserve Bank of Boston (the "FRB").FRB.  The fair value of debt securities pledged as collateral for these purposes was $374.4$456.3 million at September 30, 2017.

- Commercial loans:

Commercial real estate loans include loans secured by both owner-use and non-owner occupied real estate.  These loans are typically secured by a variety of commercial and industrial property types, including one-to-four and multi-family apartment buildings, office, industrial or mixed-use facilities, strip shopping centers, or other commercial properties, and are generally guaranteed by the principals of the borrower. Commercial real estate loans generally have repayment periods of approximately fifteen to twenty-five years.  Variable interest rate loans have a variety of adjustment terms and underlying interest rate indices, and are generally fixed for an initial period before periodic rate adjustments begin.
Commercial and industrial loans include seasonal revolving lines of credit, working capital loans, equipment financing (including equipment leases), and term loans.  Also included in commercial and industrial loans are loans partially guaranteed by the U.S. Small Business Administration ("SBA"), and loans under various programs and agencies.  Commercial and industrial credits may be unsecured loans and lines to financially strong borrowers, loans secured in whole or in part by real estate unrelated to the principal purpose of the loan or secured by inventories, equipment, or receivables, and are generally guaranteed by the principals of the borrower.  Variable rate loans and lines in this portfolio have interest rates that are periodically adjusted, with loans generally having fixed initial periods.  Commercial and industrial loans have average repayment periods of one to seven years.
Commercial construction loans include the development of residential housing and condominium projects, the development of commercial and industrial use property, and loans for the purchase and improvement of raw land.  These loans are secured in whole or in part by underlying real estate collateral and are generally guaranteed by the principals of the borrowers.  Construction lenders work to cultivate long-term relationships with established developers. The Company limits the amount of financing provided to any single developer for the construction of properties built on a speculative basis.  Funds for construction projects are disbursed as pre-specified stages of construction are completed.  Regular site inspections are performed, prior to advancing additional funds, at each construction phase, either by experienced construction lenders on staff or by independent outside inspection companies.  Commercial construction loans generally are variable rate loans and lines with interest rates that are periodically adjusted and generally have terms of one to three years.

From time to time, the Company participates with other banks in the financing of certain commercial projects.  Participating loans with other institutions provide banks the opportunity to retain customer relationships and reduce credit risk exposure among each participating bank, while providing customers with larger credit vehicles than the individual bank might be willing or able to offer independently. In some cases, the Company may act as the lead lender, originating and servicing the loans, but participating out a portion of the funding to other banks.  In other cases, the Company may participate in loans originated by other institutions. In each case, the participating bank funds a percentage of the loan commitment and takes on the related pro-rata risk.  In each case in which the Company participates in a loan, the rights and obligations of each participating bank are divided proportionately among the participating banks in an amount equal to their share of ownership and with equal priority among all banks.  When the participation qualifies as a sale under GAAP, the balances participated out to other institutions are not carried as assets on the Company's financial statements.  The Company performs an independent credit analysis of each commitment and a review of the participating institution prior to participation in the loan, and an annual review thereafter of each participating institution. Loans originated by other banks in which the Company is a participating institution are carried in the loan portfolio at the Company's pro ratapro-rata share of ownership.  Loans originated by other banks in which the Company is a participating institutionownership and amounted to $89.4$65.5 million at September 30, 2017March 31, 2019 and $85.2$63.5 million at December 31, 2016. See also "Loans serviced for others" below for information related to commercial loans participated out to various other institutions.
Letters of credit are conditional commitments issued by the Company to guarantee the financial obligation or performance of a customer to a third party.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.  If the letter of credit is drawn upon, a loan is created for the customer, generally a commercial loan, with the same criteria associated with similar commercial loans.
- Residential loans:

Enterprise originates conventional mortgage loans on one-to-four family residential properties.  These properties may serve as the borrower's primary residence, or as vacation homes or investment properties.  Loan-to-value limits vary, generally from 75% for multi-family, owner-occupied properties, up to 97% for single family, owner-occupied properties, with mortgage

insurance coverage required for loan-to-value ratios greater than 80% based on program parameters.  In addition, financing is provided for the construction of owner-occupied primary and secondary residences.  Residential mortgage loans may have terms of up to 30 years at either fixed or adjustable rates of interest.  Fixed and adjustable rate residential mortgage loans are generally originated using secondary market underwriting and documentation standards.
Depending on the current interest rate environment, management projections of future interest rates and the overall asset-liability management program of the Company, management may elect to sell those fixed and adjustable rate residential mortgage loans which are eligible for sale in the secondary market, or hold some or all of this residential loan production for the Company's portfolio.  Mortgage loans are generally not pooled for sale, but instead sold on an individual basis. The Company may retain or sell the servicing when selling the loans.  Loans sold are subject to standard secondary market underwriting and eligibility representations and warranties over the life of the loan and are subject to an early payment default period covering the first four payments for certain loan sales. Loans classified as held for sale are carried as a separate line item on the balance sheet.

- Home equity loans and lines of credit:

Home equity term loans have in the past been originated for one-to-four family residential properties with maximum original loan-to-value ratios generally up to 80% of the automated valuation or appraised value of the property securing the loan.  Home equity loan payments consist of monthly principal and interest based on amortization ranging from three to fifteen years.  The rates may be variable or fixed.
The Company originates home equity revolving lines of credit for one-to-four family residential properties with maximum original loan-to-value ratios generally up to 80% of the automated valuation or appraised value of the property securing the loan.  Home equity lines generally have interest rates that adjust monthly based on changes in the Wall Street Journal Prime Rate, although minimum rates may be applicable.  Some home equity line rates may be fixed for a period of time and then adjusted monthly thereafter. The payment schedule for home equity lines requires interest only payments for the first ten years of the lines. Generally at the end of ten years, the line may be frozen to future advances, and principal plus interest payments are collected over a fifteen-year amortization schedule or, for eligible borrowers meeting certain requirements, the line availability may be extended for an additional interest only period.
- Consumer loans:

Consumer loans consist primarily of secured or unsecured personal loans, loans under energy efficiency financing programs in conjunction with Massachusetts public utilities, and overdraft protection lines on checking accounts extended to individual customers. The aggregate amount of overdrawn deposit accounts are reclassified as loan balances.2018.

Allowance for probable loan losses methodology

On a quarterly basis, management prepares an estimate of the allowance necessary to cover estimated probable credit losses.  The Company uses a systematic methodology to measure the amount of estimated loan loss exposure inherent in the portfolio for purposes of establishing a sufficient allowance for loan losses.  The methodology makes use of specific reserves for loans individually evaluated and deemed impaired, and general reserves for larger groupspools of homogeneous loans, which are collectively evaluated relying on a combination of qualitative and quantitative factors that may affect credit quality of the pool.

There have been no material changes to the Company's underwriting practices, credit risk management system, or to the allowance assessment methodology used to estimate loan loss exposure as reported in the 2016 Annual Report on Form 10-K.  Refer to Note 4, "Allowance for Loan Losses," to the Company's consolidated financial statements contained in the 2016 Annual Report on Form 10-K for further discussion of management's methodology used to estimate a sufficient allowance for loan losses, the credit risk management function and adversely classified loan rating system.

Credit quality indicators

Early detection of credit issues is critical to minimize credit losses. Accordingly, management regularly monitors internal credit quality indicators such as the risk classification of individual loans, individual review of problem assets, past due and non-accrual loans, impaired and restructured loans, and the level of foreclosure activity, as well as trends in the general levels of these indicators. These credit quality indicators are discussed below.

Credit quality indicators

Early detection of credit issues is critical to minimize credit losses. Accordingly, management regularly monitors internal credit quality indicators such as, among others, the risk classification of adversely classified loans, past due and non-accrual loans, impaired and restructured loans, and the level of foreclosure activity. These credit quality indicators are discussed below.

Adversely classified loans

The Company's loan risk rating system classifies loans depending on risk of loss characteristics. Loans which are evaluated to be of weaker credit quality are placed on the "watch credit list" and reviewed on a more frequent basis by management. The classifications range from "substantially risk free" for the highest quality loans and loans that are secured by cash collateral, through a satisfactory range of "minimal," "moderate," "better than average," and "average" risk, to the regulatory problem-asset classifications of "criticized," for loans that may need additional monitoring, and the more severe adverse classifications of "substandard," "doubtful," and "loss" based on criteria established under banking regulations. Loans which are evaluated to be of weaker credit quality are placed on the "watch credit list" and reviewed on a more frequent basis by management.
 
Adversely classified loans may be accruing or in non-accrual status and may be additionally designated as impaired or restructured, or some combination thereof. 
The following tables present the Company's credit risk profile for each class of loan in its portfolio by internally assigned adverse risk rating category as of the periods indicated.

At September 30, 2017March 31, 2019 and December 31, 2016,2018, all loans past due 90 days or more were carried as non-accrual, in addition to those loans less than 90 days past due where reasonable doubt existed as to the full and timely collection of interest or principal that have also been designated as non-accrual, despite their payment due status shown in the tables above.

Non-accrual loans that were not adversely classified amounted to $680 thousand at September 30, 2017March 31, 2019 and $22081 thousand at December 31, 20162018. These balances primarily represented the guaranteed portions of non-performing SBA loans. The majority of the non-accrual loan balances were also carried as impaired loans during the periods noted and are discussed further below.

The ratio of non-accrual loans to total loans amounted to 0.57%0.46% at September 30, 2017March 31, 2019, and 0.47%0.49% at December 31, 20162018.

At September 30, 2017,March 31, 2019, additional funding commitments for non-accrual loans waswere not material.
 
Impaired loans
 
Impaired loans are individually significant loans for which management considers it probable that not all amounts due (principal and interest) will be collected in accordance with the original contractual terms will be collected. Impaired loans are individually evaluated for credit loss and a specific allowance reserve is assigned for the amount of the estimated probable credit loss.  The majority of impaired loans are included within the non-accrual balances; however, not every loan on non-accrual status has been designated as impaired.terms. Impaired loans include loans that have been modified in a troubled debt restructuring ("TDR"), see "Trouble"Troubled debt restructurings" below. Impaired loans are individually evaluated and exclude large groups of smaller-balance homogeneous loans, such as residential mortgage loans and consumer loans, which are collectively evaluated for impairment, and loans that are measured at fair value, unless the loan is amended in a TDR. 

The carrying value of impaired loans amounted to $30.4 million and $31.5 million at March 31, 2019 and December 31, 2018, respectively.  Total accruing impaired loans amounted to $19.3 million and $19.7 million at March 31, 2019 and December 31, 2018, respectively, while non-accrual impaired loans amounted to $11.0 million and $11.8 million as of March 31, 2019 and December 31, 2018, respectively.

At September 30, 2017March 31, 2019, additional funding commitments for impaired loans totaled $414 thousand.was not material. The Company's obligation to fulfill the additional funding commitments on impaired loans is generally contingent on the borrower's compliance with the terms of the credit agreement. If the borrower is not in compliance, additional funding commitments may or may not be made at the Company's discretion.

Troubled debt restructurings
 
Loans are designated as a TDR when, as part of an agreement to modify the original contractual terms of the loan as a result of financial difficulties of the borrower, the Bank grants the borrower a concession on the terms, that would not otherwise be considered.  Typically, such concessions may consist of one or a combination of the following: a reduction in interest rate to a below market rate, taking into account the credit quality of the note,note; extension of additional credit based on receipt of adequate collateral,collateral; or a deferment or reduction of payments (principal or interest) which materially alters the Bank's position or significantly extends the note's maturity date, such that the present value of cash flows to be received is materially less than those contractually established at the loan's origination. All loans that are modified are reviewed by the Company to identify if a TDR has occurred. TDR loans are included in the impaired loan category and, as such, these loans are individually reviewed and evaluated, and a specific reserve is assigned for the amount of the estimated probable credit loss. 

Total TDR loans, included in the impaired loan balances above, as of September 30, 2017March 31, 2019 and December 31, 20162018, were $23.623.5 million and $27.023.1 million, respectively. TDR loans on accrual status amounted to $17.319.3 million and $22.419.4 million at September 30, 2017March 31, 2019 and December 31, 20162018, respectively. TDR loans included in non-performing loans amounted to $6.3 million and $4.64.2 million at September 30, 2017March 31, 2019 and $3.7 million at December 31, 20162018, respectively.. The Company continues to work with customers particularly commercial relationships, and enters into loan modifications (which may or may not be TDRs) to the extent deemed to be necessary or appropriate while attempting to achieve the best mutual outcome given the individual financial circumstances and future prospects of the borrower.

At September 30, 2017,March 31, 2019, additional funding commitments for TDR loans totaled $390 thousand.were not material. The Company's obligation to fulfill the additional funding commitments on TDR loans is generally contingent on the borrower's compliance with the terms of the credit agreement. If the borrower is not in compliance, additional funding commitments may or may not be made at the Company's discretion.

Other real estate owned ("OREO")

Real estate acquired by the Company through foreclosure proceedings or the acceptance of a deed in lieu of foreclosure is classified as OREO. When property is acquired, it is recorded at estimated fair value of the property acquired, less estimated costs to sell, establishing a new cost basis and carried on the consolidated balance sheet in the line item "Prepaid expenses and other assets". The Company carriedestimated fair value is based on market appraisals and the Company’s internal analysis. Any loan balance in excess of the estimated realizable fair value on the date of transfer is charged to the allowance for loan losses on that date. All costs incurred thereafter in maintaining the property, as well as subsequent declines in fair value are charged to non-interest expense.

The carrying value of OREO at March 31, 2019 was $255 thousand and consisted of one property added during the three months ended March 31, 2019, compared to no OREO at September 30, 2017, December 31, 20162018 or September 30, 2016.March 31, 2018. There were no OREO sales or write downs of OREO during the three months ended March 31, 2019. During the three months ended March 31, 2018, there were no additions, sales or write downs on OREO during the nine months ended September 30, 2017 or 2016.OREO.

At September 30, 2017,both March 31, 2019 and December 31, 2018, the Company had no consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings were in process according to local requirements of the applicable jurisdictions with carrying amounts totaling $101 thousand compared with $200 thousand at December 31, 2016.jurisdictions.

Allowance for loan loss activity
 
The allowance for loan losses is an estimate of probable credit loss inherent in the loan portfolio as of the specified balance sheet dates. On a quarterly basis, management prepares an estimate of the allowance necessary to cover estimated probable credit losses.  The Company maintains the allowance at a level that it deems adequate to absorb all reasonably anticipated probable losses from specifically known and other credit risks associated with the portfolio. The allowance for loan losses is established through a provision for loan losses, a direct charge to earnings.  Loan losses are charged against the allowance when management believes that the collectability of the loan principal is unlikely.  Recoveries on loans previously charged-off are credited to the allowance.

ENTERPRISE BANCORP, INC.
Notes to the Unaudited Consolidated Interim Financial Statements

The allowance for loan losses amounted to $33.2$33.7 million at September 30, 2017,March 31, 2019, compared to $31.3$33.8 million at December 31, 2016,2018, and $31.6$34.5 million at September 30, 2016. For the nine months ended September 30, 2017 and September 30, 2016, the provision for loan losses amounted to $1.6 million and $2.5 million, respectively. The decrease in the provision for the nine months ended September 30, 2017 was due primarily to generally improving credit quality metrics and underlying collateral values, partially offset by the higher level of loan growth during the 2017 period, as compared to the 2016 period.
March 31, 2018. The allowance for loan losses to total loans ratio was 1.51%1.41% at September 30, 2017, 1.55%March 31, 2019, 1.42% at December 31, 20162018 and 1.59%1.51% at September 30, 2016.March 31, 2018. Based on management's judgment as to the existing credit risks inherent in the loan portfolio, as discussed above under the heading "Credit Quality Indicators," management believes that the Company's allowance for loan losses is adequate to absorb probable losses from specifically known and other probable credit risks associated with the portfolio as of September 30, 2017.

(5)Leases

As of March 31, 2019, the Company had 15 operating real estate leases. The Company's leased facilities are contracted under various non-cancelable operating leases, most of which provide options to the Company to extend the lease periods and include periodic rent adjustments. While the Company typically exercises its option to extend lease terms, clauses with its lease contracts allow the Company, upon notification, to terminate the lease at the end of the lease term, or any option period. Several leases also provide the Company the right of first refusal should the property be offered for sale or purchase options at specified periods mutually agreeable to the parties.  The Company has an agreement to purchase one of the leased buildings in its main campus and anticipates this transaction will be completed during the second quarter of 2019.

On January 1, 2019, the Company adopted ASU No. 2016-02, "Leases (Topic 842)." Under this ASU, as amended, lessees are required to recognize lease assets (right-of-use asset or "ROU") and lease liabilities on the balance sheet for all leases with terms longer than 12 months. For the Company, this ASU primarily impacted operating leases on our facilities, mainly branch leases, and as a result the Company recorded, on its consolidated balance sheet a lease liability of $18.0 million and ROU asset of $19.0 million on January 1, 2019 related to these leases.



23

ENTERPRISE BANCORP, INC.
Notes to the Unaudited Consolidated Interim Financial Statements

Upon adoption of this ASU, the Company elected the following practical expedients:

to not reassess, among other things, the historical lease classification, and
to use hindsight to assess lease terms and impairment of the ROU asset.

The Company excludes leases with a term of 12 months or less from the recorded lease liability and ROU asset and accounts for lease and non-lease components separately. In order to calculate the lease liability, the Company used its incremental borrowing rate as the discount rate to determine the net present value of the lease liability. In determining the term of a lease, the Company included options renewal periods that it considered reasonably certain to exercise, which generally resulted in the inclusion of all lease option periods.
The Company recognizes lease expense on a straight-line basis in the "Occupancy and Equipment Expenses" line item within the non-interest expense section of the consolidated income statement. Lease expenses, consisting of operating lease costs and variable lease costs, for the three months ended March 31, 2019 were $319 thousand. Variable lease costs and short-term lease expenses during this period were immaterial.

The weighted average remaining lease term for operating leases at March 31, 2019 was 28.5 years, and the weighted average discount rate was 3.82%.

At March 31, 2019, the remaining undiscounted cash flows by year of these lease liabilities were as follows:
(Dollars in thousands) Operating Leases
2019 (nine remaining months) $891
2020 1,179
2021 1,179
2022 1,181
2023 1,188
Thereafter 24,134
Total lease payments $29,752
Less: Imputed interest 11,881
Total $17,871

In addition, the Company currently collects rent through non-cancellable leases for a small portion of the overall square-footage within its Lowell, Massachusetts campus headquarters and at one of its branch locations. These leases are deemed immaterial.

Total customer deposits (deposits excluding brokered deposits) include reciprocal balances from checking, money market deposits and CDs received from participating banks in nationwide deposit networks as a result of our customers electing to participate in Company offered programs which allow for enhanced FDIC insurance. Essentially, the equivalent of the customers' original deposited funds comes back to the Company and are carried within the appropriate category under total customer deposits. The Company's balances in these reciprocal products were $510.5 million and $342.4 million at March 31, 2019 and December 31, 2018, respectively.

See Note 13, "Fair Value Measurements," to the Company's unaudited consolidated interim financial statements, contained below, for further information regarding the Company's fair value measurements for deposits.

(7)Borrowed Funds and Subordinated Debt
The Company had $488 thousand in borrowed funds at March 31, 2019 linked to outstanding commercial loans under various community reinvestment programs of the FHLB. At December 31, 2018, borrowed funds consisted of FHLB borrowings amounting to $100.5 million.

The Company had outstanding subordinated debt (net of deferred issuance costs) of $14.9 million at both March 31, 2019 and December 31, 2018, which consisted of $15.0 million in aggregate principal amount of Fixed-to-Floating Rate Subordinated Notes (the "Notes") issued in January 2015, with a 15 year term. Original debt issuance costs were $190 thousand and have been netted against the subordinated debt on the consolidated balance sheet in accordance with accounting guidance. These costs are being amortized to interest expense over the life of the Notes.

The Notes are intended to qualify as Tier 2 capital for regulatory purposes and pay interest at a fixed rate of 6.00% per annum through January 30, 2025, after which floating rates apply. Refer to Note 7, "Borrowed Funds and Subordinated Debt," to the Company's audited consolidated financial statements contained in the 20162018 Annual Report on Form 10-K for additional information about the Company's subordinated debt.

See Note 12, "Fair Value Measurements,2, "Investments," belowand Note 3, "Loans" to the Company's unaudited consolidated interim financial statements, contained above, for further information regarding securities and loans pledged for borrowed funds. Refer to the "Liquidity" section and "Borrowed Funds" in the "Financial Condition" section in Item 2, "Management's Discussion and Analysis," for additional information about other sources of funding available to the Company and the Company's fair value measurements for borrowed funds and subordinated debt.borrowing capacity.

(7)(8)Derivatives and Hedging Activities

Interest rateInterest-rate lock commitments related to the origination of mortgage loans that will be sold are considered derivative instruments.  The commitments to sell loans are also considered derivative instruments. The Company generally does not pool mortgage loans for sale, but instead sells the loans on an individual basis. To reduce the net interest rateinterest-rate exposure arising from its loan sale activity, the Company enters into the commitment to sell these loans at essentially the same time that the interest rateinterest-rate lock commitment is quoted on the origination of the loan. The Company estimates the fair value of these derivatives based on current secondary mortgage market prices. At September 30, 2017March 31, 2019 and December 31, 2016,2018, the estimated fair valuesvalue of the Company's interest rate lock commitments and commitments to sell these derivative instrumentsmortgage loans were considered to bedeemed immaterial.

The Company may use interest-rate contract swaps as part of its interest-rateinterest rate risk management strategy. Interest-rate swap agreements aremay be entered into as hedges against future interest-rateinterest rate fluctuations on specifically identified assets or liabilities. The Company did not havehad no derivative fair value hedges or derivative cash flow hedges at either September 30, 2017March 31, 2019 or December 31, 2016.2018.

The Company has a “Back-to-Back Swap”"Back-to-Back Swap" program whereby the Bank enters into an interest rateinterest-rate swap with a qualified commercial banking customer and simultaneously enters into an equal and opposite interest rateinterest-rate swap with a swap counterparty. The customer interest rate swap agreement allows commercial banking customers to convert a floating-rate loan payment to a fixed-rate payment.

The transaction structure effectively minimizes the Bank’sBank's net risk exposure resulting from such transactions. Customer-related credit risk is minimized by the cross collateralization of the loan and the interest rate swap agreement.

Back-to-Back Swapsswaps are not speculative butspeculative; rather, the transactions result from a service the Company provides to certain commercial customers. Back-to-Back Swapsswaps do not meet hedge accounting requirements and therefore changes in the fair value of both the customer swaps and the counterparty swaps, which have an offsetting relationship, are recognized directly in

earnings. As a result of this offsetting relationship, there were no net gains or losses recognized in income on Back-to-Back Swapsswaps during the ninethree months ended September 30, 2017March 31, 2019 or September 30, 2016.March 31, 2018.

The Company had sixEach Back-to-Back swap transaction consists of two interest-rate swaps (a customer swap and offsetting counterparty swap) and amounted to a total number of eight interest rate swaps outstanding at September 30, 2017both March 31, 2019 and December 31, 2018, with an aggregate notional amount of $29.6$37.4 million compared to four interest-rate swaps with an aggregate notional amount of $26.7and $37.7 million at December 31, 2016.on those respective dates.

Asset derivatives are included in the line item prepaid expenses and other assets and liability derivatives are included in prepaid expenses and other assets andthe accrued expenses and other liabilities line item on the consolidated balance sheets, respectively. Interest-rate swaps with the counterparty are subject to master netting agreements, while interest-rate swaps with customers are not.

By using derivative financial instruments, the Company exposes itself to counterparty creditcounterparty-credit risk. Credit risk is the risk of failure by the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative is negative, the Company owes the counterparty and, therefore, it does not possess credit risk. The credit risk in derivative instruments is mitigated by entering into transactions with highly-rated counterparties that management believes to be creditworthy. The Company has one counterparty and it was rated A and A2 by Standard & Poor and Moody, respectively, at March 31, 2019. Additionally, counterparty interest rate swaps contain provisions for collateral to be posted if the derivative exposure exceeds a threshold amount.

The Company had credit risk exposure amounting to $269 thousand and $678 thousand at March 31, 2019 and December 31, 2018, respectively, relating to interest rate swaps with counterparties. The Company held cash collateral of $200 thousand at March 31, 2019 and $850 thousand at December 31, 2018. Collateral held by the Company is restricted and not considered an asset of the Company. Therefore, it is not carried on the Company's consolidated balance sheet.

The table below presents the Company's asset derivative positions and the potential effect of those netting arrangements on its financial position, as of the periods presented. As noted above, interest-rate swaps with customers are not subject to master netting agreements and therefore are not included in the table below.

instruments is mitigated by entering into transactions with highly-rated counterparties that management believes to be creditworthy. As the swaps are subject to master netting agreements, the Company had reduced exposure relating to interest rate swaps with institutional counterparties at September 30, 2017. The Company had unsecured counterparty credit risk exposure of $428 thousand and $610 thousand on interest rate swaps at September 30, 2017 and December 31, 2016, respectively.  The counterparty was rated A / A2 by S&P and Moody’s, respectively, at September 30, 2017.

Certain counterparty interest rate swaps contain provisions that require the Company to post collateral if the derivative exposure exceeds a threshold amount. As of September 30, 2017 and December 31, 2016, the Company has not posted or received any collateral.

The Company has interest rate swaps with counterparties that contain credit-risk-related contingent provisions. These provisions provide the counterparty with the right to terminate its derivative positions and require the Company to settle its obligations under the agreements if the Company defaults on certain of its indebtedness.

The Company also participates in loans originated by third party banks, where the originating bank utilizes a back-to-back interest rateinterest-rate swap structure; however, the Company is not a party to the swap agreements. Under the terms of the loan participations, the Company has accepted contingent liabilities that would only be realized if the swaps were terminated early and there were outstanding losses not covered by the underlying borrowers and the borrowers' pledged collateral.  If applicable, the Company’s swap lossCompany's swap-loss exposure would be equal to the percentage of the Company’sCompany's participation in the underlying loan applied to the originating bank's swap loss.  At September 30, 2017both March 31, 2019 and December 31, 2016,2018, the Company had twoone such participation loans andloan. At March 31, 2019, management considers the risk of material swap lossswap-loss exposure related to this participation loan to be unlikely based on the swap market value, as well as the borrower's financial and collateral strength.

The Company’sCompany's authorized capital is divided into common stock and preferred stock. At the Company's annual meeting of shareholders held on May 2, 2017, shareholders voted to amend the Company’s Restated Articles of Organization to increase the number of shares of common stock that theThe Company is authorized to issue from 20,000,00040,000,000 shares to 40,000,000 shares.of common stock, with a par value of $0.01, and as of March 31, 2019 had 11,798,114 shares of common stock issued and outstanding. The Company is authorized to issue 1,000,000 shares of preferred stock, with a par value of $0.01. No preferred stock has been issued as of the date of this Form 10-Q. Holders of common stock are entitled to one vote per share and are entitled to receive dividends if and when declared by the Company's Board of Directors (the "Board"). Dividend and liquidation rights of the common stock may be subject to the rights of any outstanding preferred stock.

The Company has a shareholdersshareholders' rights plan. Under the plan, each share of common stock includes a right to purchase under certain circumstances one one-hundredth of a share of the Company’sCompany's Series A Junior Participating Preferred Stock, par value $0.01 per share, at a purchase price of $52.00$122.50 per one one-hundredth of a preferred share, subject to adjustment, or, in certain circumstances, to receive cash, property, shares of common stock or other securities of the Company. The rights are not presently exercisable and remain attached to the shares of common stock until the occurrence of certain triggering events that would ordinarily be associated with an unsolicited acquisition or attempted acquisition of 10% or more of the Company’sCompany's outstanding shares of common stock. The rights have no voting or dividend privileges, and unless and until they become exercisable, have no dilutive effect on the earnings of the Company. The rights will expire, unless earlier redeemed, exchanged, or otherwise rescinded by the Company, on January 13, 2018. The Company is currently evaluating the renewal of the plan in anticipation of this expiration date.2028.

The Company's stock incentive plans permit the Board of Directors to grant, under various terms, stock options (for the purchase of newly issued shares of common stock), common stock, restricted stock awards, restricted stock units and stock appreciation rights to officers and other employees, non-employee directors and consultants. These plans also allow for newly issued shares of common stock to be issued without restrictions to officers and other employees, directors and consultants. 

The Company issues stock options and restricted stock awards to officers and other employees and restricted stock awards and stock compensation in lieu of cash fees to non-employee directors. The restricted stock awards allow for the non-forfeitable receipt of dividends, and the voting of all shares, whether or not vested, throughout the vesting periods at the same proportional level as common shares outstanding. The unvested restricted stock awards are the Company's only participating securities and are included in shares outstanding. Unvested participating restricted awards amounted to 125,134124,938 shares and 141,58091,708 shares as of September 30, 2017March 31, 2019 and December 31, 2016,2018, respectively.

Upon vesting, restricted stock awards may be net share-settled to cover payment for employee tax obligations, resulting in shares of common stock being reacquired by the Company.Company and returned to the pool of shares reserved for issuance under the incentive plans. Chapter 156D of the Massachusetts General Laws, a statute known as the Massachusetts Business Corporation Act, which applies to Massachusetts corporations such as the Company, eliminates the concept of “treasury stock”"treasury stock" and provides that shares reacquired by a Massachusetts company reacquires will be treated as authorized but unissued shares.

The Company's stock incentive plans also allow for newly issued shares of common stock to be issued without restrictions to officers and other employees, non-employee directors and consultants. From time to time, the Company issues shares to community members for consulting on regional advisory councils and grants shares of fully vested stock as employee anniversary awards. These shares vest immediately and the cost, which is based on the market price on the date of grant and deemed to be immaterial, is expensed in the period in which the services are rendered. See Note 10,11, "Stock-Based Compensation," to the Company's unaudited consolidated interim financial statements, contained below, for additional information regarding the Company's stock incentive plans.

In addition to shares issued to employees, non-employee directors and consultantscommunity members for consulting on regional advisory councils, and shares issued through equity offerings, (see below), the Company maintains a dividend reinvestment and direct stock purchase plan (“DRSPP”("DRSPP") forwhich enables stockholders, and new investorsat their discretion, to elect to reinvest or purchasecash dividends paid on their shares of the Company's common stock by purchasing additional shares of common stock directly from the Company.

Pursuant to GAAP, the Company initially excludes these unrealized holding gains and losses from net income; however, they are later reported as reclassifications out of accumulated other comprehensive income into net income when the debt securities are sold. When securities are sold, the reclassification of realized gains and losses on available-for-sale securities are included on the Consolidated Statements of Income under the "non-interest income" subheading on the line item "net gains (losses) on sales of investment securities" and the related income tax expense is included in the line item "provision for income taxes," both of which are also detailed on the Consolidated Statements of Comprehensive Income under the subheading "reclassification adjustment for net gains (losses) included in net income."

These salary continuation agreements provide for predetermined fixed-cash supplemental retirement benefits to be provided for a period of 20 years after each individual reaches a defined "benefit age." The individuals covered under the SERP have reached the defined benefit age and are receiving payments under the plan. Additionally, the Company has not recognized service costs in the current or prior year as each officer had previously attained their individually defined benefit age and was fully vested under the plan.

This non-qualified plan represents a direct liability of the Company, and as such has no specific assets set aside to settle the benefit obligation.  The funded status is the aggregate amount accrued, or the "accumulated benefit obligation," which is equal to the present value of the benefits to be provided to the employee or any beneficiary.  Because the Company's benefit obligations provide for predetermined fixed-cash payments, the Company does not have any unrecognized costs to be included as a component of accumulated other comprehensive income.

Additionally, on December 11, 2018, the Board approved and adopted the Enterprise Bank Supplemental Executive Retirement and Deferred Compensation Plan.  The plan is unfunded and is maintained for the purpose of providing deferred compensation to a certain group of management employees. Please refer to Exhibit 10.17 attached to the Company's 2018 Annual Report on

Supplemental Life Insurance
 
The Company has provided supplemental life insurance through split-dollar life insurance arrangements for certain executive and senior officers on whom the Bank owns bank-owned life insurance ("BOLI").BOLI.

These arrangements provide a death benefit to the officer's designated beneficiaries that extend to postretirement periods for some of the supplemental life insurance plans. The Company has recognized a liability for these future postretirement benefits.

These non-qualified plans represent a direct liability of the Company and, as such, the Company has no specific assets set aside to settle the benefit obligation.  The funded status is the aggregate amount accrued, or the "accumulated postretirement benefit obligation," which is the present value of the post-retirement benefits associated with this arrangement.


Total net periodic post-retirement benefit cost for supplemental life insurance plans, which consisted mainly of interest costs, were $50 thousand and $45 thousand for the three months ended March 31, 2019 and March 31, 2018, respectively.

(10)(11)Stock-Based Compensation
 
The Company currently has twoone active individual stock incentive plans:plan: the 2009 plan,Enterprise Bancorp, Inc. 2016 Stock Incentive Plan, as amended in 2015, and the 2016 plan.amended. As of September 30, 2017, an aggregate of 446,860March 31, 2019, there remained 271,584 shares remain available for future grants under this plan.

Additionally, the plans.Enterprise Bancorp, Inc 2009 Stock Incentive Plan, as amended expired in March 2019 with 87,849 unissued shares. As such, this plan is closed for future grants, although awards previously granted under this plan remain outstanding and may be exercised through 2028.
 
The Company's stock-based compensation expense related to these plans includes stock options and stock awards to officers and other employees included in salary and benefits expense, and stock awards and stock compensation in lieu of cash fees to non-employee directors both included in other operating expenses.  Total stock-based compensation expense was $467 thousand and $1.3 million426 thousand for the three and nine months ended September 30, 2017March 31, 2019, respectively, compared to $444$385 thousand and $1.3 million for the three and nine months ended September 30, 2016March 31, 2018, respectively..

A tax benefit associated with employee exercises and vesting of stock compensation of approximately $111 thousand was recorded as a reduction of the Company's income tax expense for the three months ended March 31, 2019, compared with $195 thousand for the three months ended March 31, 2018. These amounts, treated as discrete tax items in the period in which they occur, will vary from year to year as a function of the volume of share-based payments vested or exercised and the then-current market price of the Company's stock in comparison to the compensation cost recognized in the Company's unaudited consolidated interim financial statements.

Stock Option Awards
 
The Company recognized stock-based compensation expense related to stock option awards of $49 thousand and $15248 thousand for the three and nine months ended September 30, 2017March 31, 2019, respectively, compared to $63 thousand and $20551 thousand for the three and nine months ended September 30, 2016March 31, 2018, respectively..

The Company utilizes the Black-Scholes option valuation model in order to determine the per share grant date fair value of option grants.

Vested options are only exercisable while the employee remains employed with the Bank and for a limited time thereafter. For all awards, if a grantee’s employment or other service relationship, such as service as a director, is terminated for any reason, then any stock options granted that have not vested as of the time of such termination generally must be forfeited, unless the Compensation Committee or the Board of Directors, as the case may be, waives such forfeiture requirement.

Stock Awards
Stock-based compensation expense recognized in association with stock awards amounted to $358 thousand and $929 thousand for the three and nine months ended September 30, 2017, respectively, compared to $322 thousand and $939 thousand for the three and nine months ended September 30, 2016, respectively.

Restricted stock awards are granted at the market price on the date of the grant. Employee awards generally vest over four years in equal portions beginning on the first anniversary date of the award or are performance based awards that vest upon the Company achieving certain predefined performance objectives. Non-employee director awards generally vest over two years in equal portions beginning on the first anniversary date of the award.

If a grantee's employment or other service relationship, such as service as a director, is terminated for any reason, then any shares of restricted stock granted that have not vested as of the time of such termination generally must be forfeited, unless the Compensation Committee or the Board of Directors, as the case may be, waives such forfeiture requirement.

The restricted stock awards allow for the receipt of dividends, and the voting of all shares, whether or not vested, throughout the vesting periods at the same proportional level as common shares outstanding.

Upon vesting, restricted stock awards may be net share-settled to cover payment for employee tax obligations, resulting in shares of common stock being reacquired by the Company.

Any shares that are returned to the Company prior to vesting or as payment for employee tax obligations upon vesting shall remain available for issuance under such plan, while the plan is still open.

Stock in Lieu of Directors' Fees
In addition to restricted stock awards discussed above, the non-employee members of the Company's Board of Directors may opt to receive newly issued shares of the Company's common stock in lieu of cash compensation for attendance at Board and Board Committee meetings.  Stock-based compensation expense related to these directors' fees amounted to $60 thousand and $206 thousand for the three and nine months ended September 30, 2017, respectively, compared to $59 thousand and $205 thousand for the three and nine months ended September 30, 2016, respectively, and is included in other operating expenses. In January 2017, non-employee directors were issued 12,992 shares of common stock in lieu of 2016 annual cash fees of $286 thousand at a market value price of $22.04 per share, the market value of the common stock on the opt-in measurement date of January 4, 2016.

For further information regarding the Company's stock awards, see Note 9, "Stockholders' Equity," to the Company's unaudited consolidated interim financial statements, contained above, under the caption "Shares Authorized and Share Issuance." There have been no material changes to the terms of the Company's stock incentive plans or the terms for vesting, forfeiture and settlement for options and restricted stock awards granted and outstanding under such plans as reported in the 2018 Annual Report on Form 10-K. Refer to Note 12, "Stock-Based Compensation Plans," to the Company's audited consolidated financial statements in the Company's 2018 Annual Report on Form 10-K for further information on the Company's stock incentive plans, stock options and restricted awards including descriptions of the assumptions used in the valuation model for stock options.

(11)(12)Earnings per shareShare
 
Basic earnings per share are calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding (including participating securities) during the year.  The Company's only participating securities are unvested restricted stock awards that contain non-forfeitable rights to dividends. See Note 8,9, "Stockholders' Equity," under the caption "Shares authorizedAuthorized and share issuance,Share Issuance," to the Company's unaudited consolidated interim financial statements above for further information regarding the Company's participating securities. Diluted earnings per share reflects the effect on weighted average shares outstanding of the number of additional shares outstanding if dilutive stock options were converted into common stock using the treasury stock method.

The table below presents the increase in average shares outstanding, using the treasury stock method, for the diluted earnings per share calculation for the periods indicated:
Three months ended September 30, Nine months ended September 30,Three months ended March 31,

Basic and diluted weighted average common shares outstanding for the nine months ended September 30, 2017 include the full impact of the 930,232 shares of common stock issued in the Offering, while the respective weighted averages for the 2016 periods were only affected by the Offering from the issue date of June 23, 2016 through period end.
There were 14,75852,478 and 29,353 stock options outstanding at March 31, 2019 and March 31, 2018, respectively that were determined to be anti-dilutive and therefore excluded from the calculation of dilutive shares for the ninethree months ended September 30, 2017.March 31, 2019 and 2018.  These stock options, which were not dilutive at that date,those dates, may potentially dilute earnings per share in the future.subsequent periods.

(12)(13)Fair Value Measurements

The FASB defines the fair value of an asset or liability to be the price which a seller would receive in an orderly transaction between market participants (an exit price) and also establishes a fair value hierarchy segregating fair value measurements using three levels of inputs: (Level 1) quoted market prices in active markets for identical assets or liabilities; (Level 2) significant other observable inputs, including quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs such as interest rates and yield curves, volatilities, prepayment speeds, credit risks and default rates which provide a reasonable basis for fair value determination or inputs derived principally from observed market data; and (Level 3) significant unobservable inputs for situations in which there is little, if any, market activity for the asset or liability.  Unobservable inputs must reflect reasonable assumptions that market participants would use in pricing the asset or liability, which are developed based on the basis of the best information available under the circumstances.

The Company did not transfer any assets between the fair value measurement levels during the ninethree months ended September 30, 2017March 31, 2019 or the year ended December 31, 20162018.

All of the Company's debt and equity securities that are considered "available-for-sale" and are carried at fair value.  The debt security category above includes federal agency obligations, commercial and residential federal agency MBS, municipal securities, corporate bonds, and certificates of deposits,CDs, as held at those dates.  The Company utilizes third-party pricing vendors to provide valuations on its debt securities.  Fair values provided by the vendors were generally determined based upon pricing matrices utilizing observable market data inputs for similar or benchmark securities in active markets and/or based on a matrix pricing methodology which employs The Bond Market Association's standard calculations for cash flow and price/yield analysis, live benchmark bond pricing and terms/condition data available from major pricing sources.  Therefore, management regards the inputs and methods used by third-party pricing vendors to be "Level 2 inputs and methods" as defined in the "fair value hierarchy." The Company periodically obtains a second price from an impartial third party on debt securities to assess the reasonableness of prices provided by the primary independent pricing vendor.

The Company's equity portfolio fair value is measured based on quoted market prices for the shares; therefore, these securities are categorized as Level 1 within the fair value hierarchy.
 
The Bank is required to purchase FHLB stock at par value in association with advances from the FHLB; thisFHLB. This stock is classified as a restricted investment and carried at cost which management believes approximates fair value; therefore, these securities are categorized as Level 3 measures. See Note 1, "Summary of Significant Accounting Policies," Item (c) "Restricted Instruments" for further information regarding the Company's fair value assessment of FHLB capital stock.

Impaired loan balances in the table above represent those collateral dependent impaired commercial loans where management has estimated the probable credit loss by comparing the loan's carrying value against the expected realizable fair value of the collateral (appraised value, or internal analysis, less estimated cost to sell, adjusted as necessary for changes in relevant valuation factors subsequent to the measurement date).  Certain inputs used in these assessments, and possible subsequent adjustments, are not always observable, and therefore, collateral dependent impaired loans are categorized as Level 3 within the fair value hierarchy.  A specific allowance is assigned to the collateral dependent impaired loan for the amount of management's estimated probable credit loss.  The specific allowances assigned to the collateral dependent impaired loans amounted to $1.6$1.1 million at September 30, 2017March 31, 2019 compared to $1.9$1.6 million at December 31, 20162018.

Real estate acquired by the Company through foreclosure proceedings or the acceptance of a deed in lieu of foreclosure is classified as OREO. When property is acquired, it is recorded at the estimated fair value of the property acquired, less estimated costs to sell, establishing a new cost basis. The estimated fair value is based on market appraisals and the Company's internal analysis. Certain inputs used in appraisals or the Company's internal analysis, are not always observable, and therefore, OREO may be categorized as Level 3 within the fair value hierarchy.

The fair values for the interest-rateinterest rate swap assets and liabilities represent a FASB Level 2 measurement and are based on settlement values adjusted for credit riskrisks and observable market interest rate curves. The settlement values are based on discounted cash flow analysis, a widely accepted valuation technique, reflecting the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. Credit risk adjustments consider factors such as the likelihood of default by the Company and its counterparties, its net exposures and remaining contractual life. The change in value of interest-rateinterest rate swap assets and liabilities attributable to credit risk was not significant during the reported periods. Refer also to Note 7,8, "Derivatives and Hedging Activities," to the Company's unaudited consolidated interim financial statements, contained above, for additional information on the Company's interest-rateinterest rate swaps.

Letters of credit are conditional commitments issued by the Company to guarantee the financial obligation or performance of a customer to a third party.  The fair value of these commitments was estimated to be the fees charged to enter into similar agreements, and accordingly these fair value measures are deemed to be FASB Level 2 measurements.  In accordance with the FASB, the estimated fair values of these commitments are carried on the consolidated balance sheet as a liability and amortized to income over the life of the letters of credit, which are typically one year.  The estimated fair value of these commitments carried on the consolidated balance sheet at September 30, 2017March 31, 2019 and December 31, 20162018 were deemed immaterial.

Interest rate lock commitments related to the origination of mortgage loans that will be sold are considered derivative instruments.  The commitments to sell loans are also considered derivative instruments. The Company generally does not pool mortgage loans for sale, but instead sells the loans on an individual basis. To reduce the net interest rate exposure arising from its loan sale activity, the Company enters into the commitment to sell these loans at essentially the same time that the interest rate lock commitment is quoted on the origination of the loan. The Company estimates the fair value of these derivatives based on current secondary mortgage market prices. These commitments are accounted for in accordance with FASB guidance.  The fair values of the Company's derivative instruments are deemed to be FASB Level 2 measurements.  At September 30, 2017March 31, 2019 and December 31, 2016,2018, the estimated fair value of the Company's interest-rateinterest rate lock commitments and commitments to sell these mortgagesmortgage loans were deemed immaterial.

The following table presents additional quantitative information about assets measured at fair value on a recurring and non-recurring basis for which the Company utilized Level 3 inputs (significant unobservable inputs for situations in which there is little, if any, market activity for the asset or liability) to determine fair value as of September 30, 2017March 31, 2019:

Excluded from the tables above are certain financial instruments with carrying values that approximated their fair value at the dates indicated, as they were short-term in nature or payable on demand.  These include cash and cash equivalents and non-term deposit accounts. The respective carrying values of these instruments would all be considered to be classified within Level 1 of their fair value hierarchy.

Also excluded from these tables are the fair values of commitments for the unused portionportions of lines of credit and letters of credit, which were estimated to be the fees currently charged to enter into similar agreements and are deemed to be immaterial, as well as commitments to originate loans whichthat were short-term, at current market rates and estimated to have no significant change in fair value.

When determining fair values noted in the tables above, in cases where quoted fair values are not available, fair values are based upon estimates using various valuation techniques.  Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.  The following methods and assumptions were used by the Company in estimating fair values of its financial instruments:

Loans held for sale: Loans held for sale are recordedat the lower of aggregate amortized cost or market value. The fair value is based on comparable market prices for loans with similar rates and terms.

Loans: The fair value of loans was determined using discounted cash flow analysis, using interest rates currently being offered by the Company.  The incremental credit risk for adversely classified loans was considered in the determination of the fair value of the loans. 
Financial liabilities: The fair values of certificates of deposit and borrowings were estimated using discounted cash flow analysis using rates offered by the Bank or advance rates offered by the FHLB on September 30, 2017 and December 31, 2016 for similar instruments.  The fair value of subordinated debt was estimated using discounted cash flow analysis using a market rate of interest at September 30, 2017 and December 31, 2016.

Notes to the Unaudited Consolidated Interim Financial Statements
 

Limitations:  The estimates of fair value of financial instruments were based on information available at September 30, 2017 and December 31, 2016 and are not indicative of the fair market value of those instruments as of the date of this Quarterly Report on Form 10-Q.  These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. The fair value of the Company's time deposit liabilities do not take into consideration the value of the Company's long-term relationships with depositors, which may have significant value.
Because no active market exists for a portion of the Company's financial instruments, fair value estimates were based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors.  These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision.  Changes in assumptions could significantly affect the estimates.

Composition of Earnings

The Company's earnings are largely dependent on its net interest income, which is the difference between interest earned on loans and investments and the cost of funding (primarily deposits and borrowings).  Net interest income expressed as a percentage of average interest earning assets is referred to as net interest margin. The Company reports net interest margin on a tax equivalent basis ("margin").

Net interest income for the three months ended September 30, 2017March 31, 2019 amounted to $25.1$28.1 million, an increase of $3.3$2.1 million, or 15%8%, compared to the same period in 2016. Net interest income for the ninethree months ended September 30, 2017 amounted to $71.5 million, an increase of $7.3 million, or 11%, compared to the nine months ended September 30, 2016.March 31, 2018. The increase in net interest income was due largely to interest-earning asset growth, primarily to loan growth.in loans. Average loan balances (including loans held for sale) increased $204.2$98.7 million and $201.6 million for the quarter and nine months ended September 30, 2017, respectively, compared to the 2016 respective period averages. Margin was 4.03% for the three months ended September 30, 2017 and 3.90%March 31, 2019, compared to the same 2018 period average. Tax equivalent margin ("T/E margin") was 3.98% for the three months ended June 30, 2017, while net interest margin was 3.86%March 31, 2019, compared to 3.95% for the three months ended September 30, 2016. Margin was 3.95% for the nine months ended September 30, 2017, compared to 3.96% for the nine months ended September 30, 2016. See the discussion under the heading "Results of Operations" below, in this Item 2, for further information regarding changes in margin.

The re-pricing frequency of the Company’s assets and liabilities are not identical, and therefore subject the Company to the risk of adverse changes in interest rates. This is often referred to as “interest rate risk” and is reviewed in more detail in Part I, Item 3, “Quantitative and Qualitative Disclosures About Market Risk,” of this Form 10-Q and in Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” of the Company's 2016 Annual Report on Form 10-K.March 31, 2018.

For the three months ended September 30, 2017March 31, 2019 there was a negative provision to the allowance for loan losses of $400 thousand, compared to a provision of $1.6 million for the three months ended March 31, 2018. The primary factor in the decrease in the year-to-date provision for loan losses compared to the prior year was a reduction in the balance of the allowance for loan losses allocated to impaired, adversely classified, and September 30, 2016,criticized loans of $81 thousand for the three months ended March 31, 2019, compared to an increase of $1.4 million during the three months ended March 31, 2018.

Forfor the ninethree months ended September 30, 2017 and September 30, 2016, the provision for loan losses amounted to $1.6 million and $2.5 million, respectively. The decrease in the provision for the nine months ended September 30, 2017, was due primarily to generally improved credit quality metrics and underlying collateral values, partially offset by increased loan growthMarch 31, 2019 compared to the prior year period.were:

Impacting the non-performing loans ratio in the current period, among other changes, were new impaired/non-accrual status classifications of two larger commercial relationships totaling approximately $4.5 million, which, based on a review of their individual business circumstances, management determined that no reserves were necessary as of September 30, 2017.

However, the reserves allocated to these loans declined $472 thousand over the same period due to generally improved collateral values on impaired loans.

Additionally, loan sale income decreased while deposit and interchange fees and investment advisory fees increased in the current quarter compared to the same period in 2016.

Sources and Uses of Funds
 
The Company's primary sources of funds are customer and brokered deposits, Federal Home Loan Bank ("FHLB")FHLB borrowings, current earnings and proceeds from the sales, maturities and pay-downs on loans and investment securities.  The Company may also, from time to time, utilize overnight borrowings from correspondent banks.

The Company's sources of funds are intended to be used to originate loans, purchase investment securities, conduct operations, expand the branch network, and pay dividends to stockholders.
 
The investment portfolio is primarily used to provide liquidity, manage the Company's asset-liability position and to invest excess funds, providing additional sources of revenue. Total investments, one of the key componentssecond-key component of interest earning assets, amounted to $385.9460.8 million at September 30, 2017March 31, 2019, an increase of $11.2$27.9 million, or 3%6%, since December 31, 2016,2018, and comprised 14%15% of total assets at September 30, 2017both March 31, 2019 and 15% of total assets at December 31, 2016.2018.

Management's preferred strategy for funding asset growth is to grow relationship-based deposit balances, preferably transactional deposits (comprised of demand depositnon-interest checking accounts, interest-bearing checking accounts and traditional savings accounts).  Asset growth in excess of transactional deposits is typically funded through non-transactional deposits (comprised of money market accounts, commercial tiered rate or "investment savings" accounts and term certificates of deposit)CDs) and wholesale funding (brokered deposits and borrowed funds).
 
At September 30, 2017,March 31, 2019, customer deposits (total deposits excluding brokered deposits) amounted to $2.22$2.73 billion,, an increase of $10.6 million, from December 31, 2016 balances. During the period, the increase was primarily due to increases in non-interest bearing checking accounts, largely offset by decreases in money market account balances.

Wholesale funding amounted to $231.7 million at September 30, 2017, comprising 9% or 89% of total assets, compared to $70.0 million at December 31, 2016,$2.51 billion, or 3%85% of total assets, an increase of $161.7 million. at December 31, 2018.

While management recognizes that such investments increase expenses in the short term, Enterprise believes that such initiatives are a necessary investment in the long-term growth and earnings potential of the Company and will help the Company to capitalize on current opportunities in the current marketplace for community banks such as Enterprise. However, lower than expected returns on these investments, such as slower than anticipated loan and deposit growth in new branches and/or lower than expected feeadoption rates or other income generated from new technology or initiatives, could decrease anticipated revenues and net income on such investments in the future.

Changes in government regulation or oversight could affect the Company in substantial and unpredictable ways. The President has signed many executive orders calling for the administration to review various U.S. financial laws and regulations. The full scope of the current administration's legislative agenda is not yet fully known, but it may include certain deregulatory measures for the banking industry, including the structure and powers of the Consumer Finance Protection Bureau and other areas under the Dodd-Frank Act in addition to extensive corporate tax reform proposals. Accordingly, it is difficult to anticipate the continued impact that this expansive legislation, if or when fully enacted, will have on the Company, its customers and the financial industry generally. The Company maintains a Compliance Management Program (the "CMP") designed to meet regulatory and legislative requirements.  The CMP provides a framework for tracking and implementing regulatory changes,

monitoring the effectiveness of policies and procedures, conducting compliance risk assessments, and educating employees in matters relating to regulatory compliance. 

Operational risk includes the threat of loss from inadequate or failed internal processes, people, systems or external events, due to, among other things: fraud or error; the inability to deliver products or services; failure to maintain a competitive position; lack of, or insufficient information security, cyber-security or physical security; inadequate procedures or controls followed by third-party service providers; or violations of ethical standards. In addition to intensive and ongoing employee training, employee and customer awareness campaigns, controls to manage operational risk include, but are not limited to, technology administration, information security, third-party management, and disaster recovery and business continuity planning. Any system of controls or contingency plan, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the controls and procedures will be met. Any breakdown in the integrity of these information systems, infrastructure, or cyber-security measures, or the Company's inability to identify, respond and correct such breakdown, could result in a loss of customer business, expose customers' personal information to unauthorized parties, damage the Company's reputation, subject the Company to increase costs and additional regulatory scrutiny, and expose the Company to civil litigation and possible financial liability, any of which could have a material adverse effect on the Company's business, financial condition and results of operations.

Accounting Policies/Critical Accounting Estimates

As discussed in the Company's 2016 Annual Report on Form 10-K, the three most significant areas in which management applies critical assumptions and estimates that are particularly susceptible to change relate to the determination of the allowance for loan losses, impairment review of investment securities and the impairment review of goodwill.  The Company has not changed its significant accounting and reporting policies from those disclosed in its 2016 Annual Report on Form 10-K.

obligations of each participating bank are divided proportionately among the participating banks in an amount equal to their share of ownership and with equal priority among all banks. Each participation is governed by individual participation agreements executed by the lead bank and the participant at loan origination. Participating loans with other institutions provide banks the opportunity to retain customer relationships and reduce credit risk exposure among each participating bank, while providing customers with larger credit vehicles than the individual bank might be willing or able to offer independently.
 
See Note 3, "Loans," to the Company's unaudited consolidated interim financial statements contained in Item 1 of this Form 10-Q for information on loans serviced for others and loans pledged as collateral.

Credit Risk
 
Inherent in the lending process is the risk of loss due to customer non-payment, or "credit risk." The Company's commercial lending focus may entail significant additional credit risks compared to long-term financing on existing, owner-occupied residential real estate.  The Company seeks to lessen its credit risk exposure by managing its loan portfolio to avoid concentration by industry, and relationship size, and source of repayment, and through sound underwriting practices and the credit risk management function; however, management recognizes that loan losses will occur and that the amount of these losses will fluctuate depending on the risk characteristics of the loan portfolio and economic conditions.

Non-performing assets are comprised of non-accrual loans, deposit account overdrafts that are more than 90 days past due and OREO.Other real estate owned ("OREO").  The designation of a loan or other asset as non-performing does not necessarily indicate that loan principal and interest will ultimately be uncollectible.  However, management recognizes the greater risk characteristics of these assets and therefore considers the potential risk of loss on assets included in this category in evaluating the adequacy of the allowance for loan losses.  The level of delinquent and non-performing assets is largely a function of economic conditions and the overall banking environment and the individual business circumstances of borrowers.  Despite prudent loan underwriting, adverse changes within the Company's market area, or deterioration in local, regional or national economic conditions, could negatively impact the Company's level of non-performing assets in the future.

The net increase in non-accrual loans since the prior periods was due primarily to the migration of two large commercial relationships in the second quarter of 2017, totaling approximately $4.5 million that were also carried as adversely rated/impaired credits on the Company's "watched" credit loan listing for closer monitoring at September 30, 2017. These additions, among others, were partially offset by principal paydowns and credit rating upgrades during the period. The majority of non-accrual loans were also carried as impaired loans during the periods and the changes since December 31, 20162018 are discussed further below.

At September 30, 2017March 31, 2019 and December 31, 2016,2018, the Company had adversely classified loans (loans carrying "substandard," "doubtful" or "loss" classifications) amounting to $29.2$34.6 million and $34.3$35.5 million, respectively. Total adversely classified loans amounted to 1.32%1.45% of total loans at September 30, 2017 asMarch 31, 2019, compared to 1.70%1.49% at December 31, 2016.2018. Adversely classified loans that were performing but possessed potential weaknesses and, as a result, could ultimately become non-performing loans amounted to $16.7$23.7 million at September 30, 2017March 31, 2019 and $25.1$23.8 million at December 31, 2016.2018.  The remaining balances of adversely classified loans were non-accrual loans, amounting to $12.5$11.0 million at September 30, 2017March 31, 2019 and $9.3$11.7 million at December 31, 2016.2018.  Non-accrual loans that were not adversely classified amounted to $6$80 thousand and $220$81 thousand at September 30, 2017March 31, 2019 and December 31, 2016,2018, respectively, and primarily represented the guaranteed portions of non-performing SBA loans.

The decline in adversely classifieds was due primarily to payoffs, net principal paydowns, and net credit rating upgrades during the year, particularly of several commercial relationships based on a review of their individual business circumstances.

Total impaired loans amounted to $29.730.4 million and $31.831.5 million at September 30, 2017March 31, 2019 and December 31, 20162018, respectively.  Total accruing impaired loans amounted to $17.3$19.3 million and $22.4$19.7 million at September 30, 2017March 31, 2019 and December 31, 2016,2018, respectively, while non-accrual impaired loans amounted to $12.4$11.0 million and $9.4$11.8 million as of September 30, 2017March 31, 2019 and December 31, 2016,2018, respectively. The increase in non-accrual impaired loans was primarily due to the two larger commercial relationships noted above, which, based on a review of their individual business circumstances, management determined that no reserves were necessary on these relationships as of September 30, 2017.

In management's opinion, the majority of impaired loan balances at September 30, 2017March 31, 2019 and December 31, 20162018 were supported by expected future cash flows or, for those collateral dependent loans, the net realizable value of the underlying collateral. Based on management's assessment at September 30, 2017, impaired loans totaling $23.7 million required no specific reserves and impaired loans totaling $6.0 million required specific reserve allocations of $2.2 million.  At DecemberMarch 31, 20162019, impaired loans totaling $25.7 million required no specific reserves and impaired loans totaling $6.14.7 million required specific reserve allocations of $2.62.1 million.  At December 31, 2018, impaired

Total TDR loans included in the impaired loan amounts above as of September 30, 2017March 31, 2019 and December 31, 20162018 were $23.6$23.5 million and $27.0$23.1 million, respectively.  TDR loans on accrual status amounted to $17.3$19.3 million and $22.4$19.4 million at September 30, 2017March 31, 2019 and December 31, 2016,2018, respectively. TDR loans included in non-performing loans amounted to $6.3 million and $4.6$4.2 million at September 30, 2017March 31, 2019 and $3.7 million at December 31, 2016, respectively.2018.  The Company continues to work with customers particularly commercial relationships, and enters into loan modifications (which may or may not be TDRs) to the extent deemed to be necessary or appropriate while attempting to achieve the best mutual outcome given the individual financial circumstances and future prospects of the borrower.

The Company carried one OREO property at March 31, 2019 with a carry value of $255 thousand, and no OREO at September 30, 2017, December 31, 2016 and September 30, 2016.2018 or March 31, 2018. There were no other additions, sales or writedownswrite-downs on OREO during the ninethree months ended September 30, 2017March 31, 2019 or 2016.2018.

Allowance for Loan Losses

The allowance for loan losses is an estimate of probable credit riskloss inherent in the loan portfolio as of the specified balance sheet dates. On a quarterly basis, management prepares an estimate of the allowance necessary to cover estimated probable credit losses.  The Company maintains the allowance at a level that it deems adequate to absorb all reasonably anticipated probable losses from specifically known and other credit risks associated with the portfolio. Management closely monitors the credit quality of individual delinquent and non-performing relationships, industry concentrations, the local and regional real estate market and current economic conditions. 

There have been no material changes to the Company's underwriting practices, credit risk management system, or to the allowance assessment methodology used to estimate loan loss exposure as reported in the 2016 Annual Report on Form 10-K.  Please refer to Note 4, "Allowance for Loan Losses," to the Company's audited consolidated financial statements contained in the 20162018 Annual Report on Form 10-K for further discussion of management's methodology used to estimate a sufficient allowance for loan losses, the credit risk management function and adversely classified loan rating system.10-K. 

The allowance for loan losses to total loans ratio was 1.51%1.41% at September 30, 2017, 1.55%March 31, 2019, 1.42% at December 31, 2016,2018, and 1.59%1.51% at September 30, 2016.March 31, 2018. General improvement in economic metrics, partially offset by individual loan downgrades to adversely classified and impaired loans, which have continued to occur due to individual business circumstances, have contributed to the gradual decline in the allowance to total loans ratio. Based on the foregoing, as well as management's judgment as to the existing credit risks inherent in the loan portfolio, as discussed above under the headings "Credit Risk" and "Asset Quality," management believes that the Company's allowance for loan losses is adequate to absorb probable losses from specifically known and other probable credit risks associated with the portfolio as of September 30, 2017March 31, 2019.

From time to time, managementManagement utilizes brokered deposits as cost effective wholesale funding sources to support continued loan growth and as part of the Company's asset-liability management strategy to protect against rising rates. Brokered deposits may be comprised of non-reciprocal overnight money market deposits and selected term CDs gathered from nationwide bank networks or from large money center banks; however, at September 30, 2017,March 31, 2019, December 31, 2016,2018, and September 30, 2016March 31, 2018 brokered deposits were comprised only of brokered CDs.

Subordinated Debt

The Company had outstanding subordinated debt of $14.814.9 million (net of deferred issuance costs) of outstanding subordinated debt at September 30, 2017March 31, 2019, December 31, 20162018 and September 30, 2016,March 31, 2018, which consisted of $15.0 million in aggregate principal amount of Fixed-to-Floating Rate Subordinated Notes (the "Notes") issued in January 2015, in a private placement to an accredited investor. See also Note 6,7, "Borrowed Funds and Subordinated Debt," to the Company's unaudited consolidated interim financial statements contained in Item 1 above, for further information regarding the Company's subordinated debt.

Liquidity
 
Liquidity is the ability to meet cash needs arising from, among other things, fluctuations in loans, investments, deposits and borrowings.  Liquidity management is the coordination of activities so that cash needs are anticipated and met readily and efficiently.  The Company's liquidity policies are set and monitored by the Company's Board of Directors.directors ( the "Board").  The duties and responsibilities related to asset-liability management matters are also covered by the Board of Directors.Board. The Company's asset-liability objectives are to engage in sound balance sheet management strategies, maintain liquidity, provide and enhance access to a diverse and stable source of funds, provide competitively priced and attractive products to customers and conduct funding at a low costlow-cost relative to current market conditions.  Funds gathered are used to support current commitments, to fund earning asset growth, and to take advantage of selected leverage opportunities.
 
The Company's liquidity is maintained by projecting cash needs, balancing maturing assets with maturing liabilities, monitoring various liquidity ratios, monitoring deposit flows, maintaining cash flow within the investment portfolio, and maintaining wholesale funding resources. 

At September 30, 2017March 31, 2019, the Company's wholesale funding sources primarily included borrowing capacity at the FHLB and brokered deposits. In addition, the Company maintains overnight fed fund purchase arrangements with correspondent banks and has access to the FRB Discount Window.

Management believes that the Company has adequate liquidity to meet its obligations. However, if, as a result of general economic conditions or other events, causes these sources of external funding to become restricted or are eliminated, the Company may not be able to raise adequate funds or may incur substantially higher funding costs or operating restrictions in order to raise the necessary funds to support the Company's operations and growth.

The Company has in the past also increased capital and liquidity by offering shares of the Company's common stock for sale to its existing stockholders and new investors and through the issuance of subordinated debt. See "Capital Resources," below for information on the Company's capital planning.

Capital Resources
 
Capital planning by the Company and the Bank considers current needs and anticipated future growth.  Historically, the primary sources of capital for the Company and the Bank have been common stock issuances and proceeds from the issuance of subordinated debt. Ongoing sources of capital include the retention of earnings, less dividends paid, proceeds from the exercise of employee stock options and proceeds from purchases of shares pursuant to the Company’s Company's dividend reinvestment plan and direct stock purchase plan (together, the "DRSPP"). Additional sources of capital for the Company and the Bank have been proceeds from the issuance of

common stock and proceeds from the issuance of subordinated debt. The Company believes its current capital is adequate to support ongoing operations.

Since January 1, 2015, the Company has been subject to increasing capital ratios, with a phase in period that extends to January 2019, as a result of regulation adopted by the federal bank regulatory agencies known as the “Basel III Rules.”

Net gains (losses) on sales of investment securities decreased by $830 thousand in the third quarter of 2017, predominately from losses of $1.6 million realized from a debt security portfolio restructuring, largely offset by gains on equity sales in the current quarter of $1.3 million.

Net gain on loan sales decreased $110 thousand, or 56%, primarily due to lower volume in the third quarter of 2017 compared to the same period in 2016.

Non-Interest Expense
Non-interest expense for the three months ended September 30, 2017 amounted to $18.8 million, an increase of $1.4 million, or 8%, compared to the prior period in 2016. The significant changes are discussed below:
Salaries and employee benefits increased by $1.2 million, or 11%, primarily to support the Company's strategic growth and market expansion initiatives since the prior period.

Occupancy and equipment expense increased by $134 thousand, or 7%, mainly due to investments in our facilities, including new branches, the overall branch network, and operations buildings.

Income Taxes

The effective tax rate for the three months ended September 30, 2017, was 35.4%, compared to 32.3% for the three months ended September 30, 2016. The increase in rate was primarily due to higher levels of projected taxable income.

Item 3 -Quantitative and Qualitative Disclosures About Market Risk

The Company's primary market risk is interest rate risk. Oversight of interest rate risk management is the responsibility of the Company's Board of Directors (the "Board"). Annually, the Board reviews and approves the Company's asset-liability management policy, which provides management with guidelines for controlling interest rate risk, as measured through net interest income sensitivity toThere have been no material changes in interest rates, within certain tolerance levels. The Board also establishes and monitors guidelines for the Company's liquidity, capital ratios and asset-liability management.

The Company's asset-liability management strategies and guidelines are reviewed on a periodic basis by management and presented and discussed with the Board. These strategies and guidelines are revised based on changes in interest rate levels, general economic conditions, competition in the marketplace, the current interest rate risk position of the Company, anticipated growth and other factors.

One of the principal factors in maintaining planned levels of net interest income is the ability to design effective strategies to manage the impact of interest rate changes on future net interest income. Quarterly, management completes a net interest income sensitivity analysis, which is regularly presented to the Board. This analysis includes a simulationresults of the Company's net interest income under various interest rate scenarios. Variationssensitivity analysis as reported in the interest rateCompany's 2018 Annual Report on Form 10-K. The Company can be subject to margin compression depending on the economic environment affect numerous factors, including prepayment speeds, reinvestment rates, maturitiesand the shape of investments (due to call provisions), and interest rates on various asset and liability accounts.

the yield curve. Under the Company's current balance sheet position, the Company's margin generally performs slightly better over time in a rising rate environment, while it generally decreases in a declining rate environment and when the yield curve is flattening or inverted. The Company can be subject to margin compression depending on the economic environment and the shape of the yield curve.

In a flattening yield curve scenario, margin compression occurs as the spread between the cost of funding and the yield on interest earning assets narrows. Under this scenario the degree of margin compression is highly dependent on the Company's ability to fund asset growth through lower cost deposits. However, if the curve is flattening, while short-term rates are rising, the adverse impact on margin may be somewhat delayed, as increases in the Prime Rate will initially result in the Company's asset yields re-pricing more quickly than funding costs. After a protracted period of flat rates, the Federal Open Market Committee had begun to increase the fed funds target rate, with three 25 basis point increases since their December 2016 meeting.

In an inverted yield curve situation, shorter-term rates exceed longer-term rates, and the impact on margin is similar but more adverse than the flat curve scenario. Again, however, the extent of the impact on margin is highly dependent on the Company's balance sheet mix.

In a declining rate environment, margin compression will eventually occur as the yield on interest earning assets decreases more rapidly than decreases in funding costs. The primary causes would be the impact of interest rate decreases (including decreases in the Prime Rate) on adjustable rate loans and the fact that decreases in deposit rates may be limited or lag decreases in the Prime Rate.

There have been no material changes in the results of the Company's net interest income sensitivity analysis as reported in the Company's 2016 Annual Report on Form 10-K. At September 30, 2017, management continues to considerMarch 31, 2019, the Company's primary interest rate risk exposure continues to be margin compression that may result from changes in interest rates and/or changes in the mix of the Company's balance sheet components. This would include the mix of fixed versus variable rate loans and investments on the asset side,within assets, and higher cost versus lower cost deposits and overnight borrowings versus term borrowings and certificates of deposit on the liability side.within liabilities. Refer to heading “Results"Results of Operations”Operations" contained within Management’sManagement's Discussion and Analysis of Financial Condition and Results of Operations for further discussion of margin.
