BOSTON PRIVATE FINANCIAL HOLDINGS, INC. AND SUBSIDIARIES

Notes to Unaudited Consolidated Financial Statements

1.     Basis of Presentation and Summary of Significant Accounting Policies

Boston Private Financial Holdings, Inc. (the “Company” or “BPFH”), is a bank holding company (the “Holding Company”) with four reportable segments: Private Banking, Wealth Management and Trust, Investment Management, and Wealth Advisory.

The Private Banking segment is comprised of the banking operations of Boston Private Bank & Trust Company (the “Bank” or “Boston Private Bank”), a trust company chartered by The Commonwealth of Massachusetts, insured by the Federal Deposit Insurance Corporation (the “FDIC”), and a wholly-owned subsidiary of the Company. Boston Private Bank is a member of the Federal Reserve Bank of Boston. Boston Private Bank primarily operates in three geographic markets: New England, the San Francisco Bay Area, and Southern California.

The Wealth Management and Trust segment is comprised of the operations of Boston Private Wealth LLC (“Boston Private Wealth”), a wholly-owned subsidiary of Boston Private Bank, and the trust operations of Boston Private Bank. The segment offers investment management, wealth management, family office, and trust services to individuals, families, and institutions. The Wealth Management and Trust segment operates in New England; South Florida; California; and Madison, Wisconsin.

The Investment Management segment had two consolidated affiliates, Dalton, Greiner, Hartman, Maher & Co., LLC (“DGHM”) and Anchor Capital Advisors, LLC (“Anchor”) (together, the “Investment Managers”) included in its results for the first quarter of 2018, while the assets and liabilities of Anchor were classified as held for sale. Assets held for sale were$60.2 million and $58.8 million at March 31, 2018 and December 31, 2017, respectively, and liabilities held for sale were $4.7 million and $3.2 million at March 31, 2018 and December 31, 2017, respectively. In December 2017, the Company entered into an agreement to sell its entire ownership interest in Anchor in a transaction that would result in Anchor being majority-owned by members of its management team. The transaction closed in April 2018.

The Wealth Advisory segment has two consolidated affiliates, consisting of KLS Professional Advisors Group, LLC (“KLS”) and Bingham, Osborn & Scarborough, LLC (“BOS”) (together, the “Wealth Advisors” and, together with the Wealth Management and Trust and Investment Management segments, the “Wealth and Investment businesses”).

The Company conducts substantially all of its business through its four reportable segments. All significant intercompany accounts and transactions have been eliminated in consolidation.

The unaudited interim consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), and include all necessary adjustments of a normal recurring nature which, in the opinion of management, are required for a fair presentation of the results of operations and financial condition of the Company. The interim results of consolidated operations are not necessarily indicative of the results for the entire year.

The information in this report should be read in conjunction with the consolidated financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the Securities and Exchange Commission (“SEC”). Prior period amounts are reclassified whenever necessary to conform to the current period presentation.

The Company’s significant accounting policies are described in Part II. Item 8. “Financial Statements and Supplementary Data - Note 1: Basis of Presentation and Summary of Significant Accounting Policies” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the SEC. For interim reporting purposes, the Company follows the same significant accounting policies, except for the following new accounting pronouncements from the Financial Accounting Standards Board (the “FASB”) that were adopted effective January 1, 2018:

• Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”). As a result of implementing this standard, the Company reclassified $5 thousand in unrealized losses on derivatives related to hedge ineffectiveness from accumulated other comprehensive income to retained earnings as of January 1, 2018. This ASU will provide more flexibility in the Company’s risk management activities and we believe it will enhance the Company’s ability to employ risk management strategies, while improving the transparency and understanding of those strategies for financial statement users.

8

• ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (“ASU 2017-07”). This amendment requires an employer to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. As a result of the retrospective adoption of this ASU, $160 thousand for the three months ended March 31, 2017 has been reclassified from salaries and employee benefits expense to other expense within the Company’s consolidated statement of operations. For the three months ended March 31, 2018, $135 thousand is presented within other expense that would have been presented within salaries and employee benefits prior to adoption of ASU 2017-07.

• ASU 2016-15, Statement of Cash Flows (Topic 230) (“ASU 2016-15”).  This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. This ASU is effective for the Company beginning on January 1, 2018. The guidance requires application using a retrospective transition method. This ASU did not have an impact on the Company’s consolidated financial statements.

• ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). This amendment requires equity investments to be measured at fair value with changes in fair value, net of tax, recognized in net income. As a result of implementing this standard, the Company reclassified $339 thousand in unrealized gains on available-for-sale equity investments, net of tax, from accumulated other comprehensive income to retained earnings as of January 1, 2018.

• ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which was subsequently amended by additional ASUs, including ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) and ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, collectively, “ASU 2014-09 et al.” ASU 2014-09 et al. was adopted using the modified retrospective transition method as of January 1, 2018, however no cumulative effect adjustment was required. This new guidance was applied to all revenue contracts in place at the date of adoption. See Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 13: Revenue Recognition” for further details.

_____________________

(1) See Part II. Item 8. “Financial Statements and Supplementary Data - Note 14: Noncontrolling Interests” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 for a description of the redemption values related to the redeemable noncontrolling interests. In accordance with the FASB Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”), an increase in redemption value from period to period reduces income attributable to common shareholders. Decreases in redemption value from period to period increase income attributable to common shareholders, but only to the extent that the cumulative change in redemption value remains a cumulative increase since adoption of this standard in the first quarter of 2009.

(2) The diluted EPS computations for the three months ended March 31, 2018 and 2017 do not assume the conversion, exercise, or contingent issuance of the following shares for the following periods because the result would have been anti-dilutive for the periods indicated. As a result of the anti-dilution, the potential common shares excluded from the diluted EPS computation are as follows:

	Three months ended March 31,
	2018	2017
Shares excluded due to exercise price exceeding the average market price of common shares during the period (total outstanding):	(In thousands)

3.    Reportable segments

Management Reporting

The Company has four reportable segments (Private Banking, Wealth Management and Trust, Investment Management, and Wealth Advisory), and the Holding Company (Boston Private Financial Holdings, Inc.).

(1)  All mortgage-backed securities are guaranteed by U.S. government agencies or government-sponsored entities.

As of March 31, 2018, the U.S. government and agencies securities, government-sponsored entities securities and mortgage-backed securities in the first table above had current Standard and Poor’s credit ratings of AAA. The municipal bonds in the first table above had a current Standard and Poor’s credit rating of at least AA-. At March 31, 2018, the Company does not consider these investments other-than-temporarily impaired because the decline in fair value on investments is primarily attributed to changes in interest rates and not credit quality.

At March 31, 2018 and December 31, 2017, the amount of investment securities in an unrealized loss position greater than 12 months, as well as in total, was primarily due to changes in interest rates. As of March 31, 2018, the Company had no intent to sell any securities in an unrealized loss position and it is not more likely than not that the Company would be forced to sell any of these securities prior to the full recovery of all unrealized loss amounts.

Cost method investments, which are included in other assets, can be temporarily impaired when the fair values decline below the amortized costs of the individual investments. There were no cost method investments with unrealized losses as of March 31, 2018 or December 31, 2017. The Company’s cost method investments primarily include low income housing partnerships which generate tax credits. The Company also holds partnership interests in venture capital funds formed to provide financing to small businesses and to promote community development. The Company had $41.8 million and $39.4 million in cost method investments included in other assets as of March 31, 2018 and December 31, 2017, respectively.

5.    Fair Value Measurements

Fair value is defined under GAAP as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants on the measurement date. The Company determines the fair values of its financial instruments based on the fair value hierarchy established in ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 describes three levels of inputs that may be used to measure fair value. Financial instruments are considered Level 1 when valuation can be based on quoted prices in active markets for identical assets or liabilities. Level 2 financial instruments are valued using quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or models using inputs that are observable or can be corroborated by observable market data of substantially the full term of the assets or liabilities. Financial instruments are considered Level 3 when their values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable and when determination of the fair value requires significant management judgment or estimation.

Available-for-sale Level 1 securities are valued with prices quoted in active markets and include U.S. Treasury securities (which are categorized as U.S. government and agencies securities) and equities (which are categorized as other available-for-sale securities). Available-for-sale Level 2 securities generally have quoted prices but are traded less frequently than exchange-traded securities and can be priced using market data from similar assets and include government-sponsored entities securities, municipal bonds, mortgage-backed securities, and certain investments in SBA loans (which are categorized as U.S. government and agencies securities). No investments held as of March 31, 2018 or December 31, 2017 were categorized as Level 3. There were no changes in the valuation techniques used for measuring the fair value of available-for-sale securities in the three months ended March 31, 2018.

In managing its interest rate and credit risk, the Company utilizes derivative instruments including interest rate customer swaps, interest rate swaps, and risk participation agreements. As a service to its customers, the Company may utilize derivative instruments including customer foreign exchange forward contracts to manage its foreign exchange risk, if any. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities, and therefore, they have been categorized as a Level 2 measurement as of March 31, 2018 and December 31, 2017. See Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 8: Derivatives and Hedging Activities” for further details.

To comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Counterparty exposure is evaluated by netting positions that are subject to master netting agreements, as well as considering the amount of collateral securing the position.

The Company has determined that the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, although the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy as of March 31, 2018 and December 31, 2017.

Other investments, which are not considered available-for-sale investments, consist of publicly traded mutual fund investments held in deferred compensation trusts that are valued at prices quoted in active markets. Therefore, they have been categorized as a Level 1 measurement as of March 31, 2018 and December 31, 2017.

There were no transfers between levels for assets or liabilities recorded at fair value on a recurring basis during the three months endedMarch 31, 2018 and 2017.

There were no Level 3 assets valued on a recurring basis at March 31, 2018 or December 31, 2017.

The following table presents the Company’s assets and liabilities measured at fair value on a non-recurring basis during the period ended March 31, 2018, aggregated by the level in the fair value hierarchy within which those measurements fall. There were no collateral-dependent impaired loans held at March 31, 2017 that had write-downs in fair value or whose specific reserve changed during the first three months of 2017.

Impaired Loans	$	1,835	Appraisals of Collateral	Discount for costs to sell	0% - 24%	14%
				Appraisal adjustments	0% - 26%	16%

Impaired loans include those loans that were adjusted to the fair value of underlying collateral as required under ASC 310, Receivables. The amount does not include impaired loans that are measured based on expected future cash flows discounted at the respective loan’s original effective interest rate, as that amount is not considered a fair value measurement. The Company uses appraisals, which management may adjust to reflect estimated fair value declines, or apply other discounts to appraised values for unobservable factors resulting from its knowledge of the property or consideration of broker quotes. The appraisers use a market, income, and/or a cost approach in determining the value of the collateral. Therefore they have been categorized as a Level 3 measurement.

The estimated fair values have been determined by using available quoted market information or other appropriate valuation methodologies. The aggregate fair value amounts presented above do not represent the underlying value of the financial assets and liabilities of the Company taken as a whole as they do not reflect any premium or discount the Company might recognize if the assets were sold or the liabilities sold, settled, or redeemed. An excess of fair value over book value on financial assets represents a premium, or gain, the Company might recognize if the assets were sold, while an excess of book value over fair value on financial liabilities represents a premium, or gain, the Company might recognize if the liabilities were

Notes to Unaudited Consolidated Financial Statements - (Continued)

sold, settled, or redeemed prior to maturity. Conversely, losses would be recognized if assets were sold where the book value exceeded the fair value or liabilities were sold where the fair value exceeded the book value.

The fair value estimates provided are made at a specific point in time, based on relevant market information and the characteristics of the financial instrument. The estimates do not provide for any premiums or discounts that could result from concentrations of ownership of a financial instrument. Because no active market exists for some of the Company’s financial instruments, certain fair value estimates are based on subjective judgments regarding current economic conditions, risk characteristics of the financial instruments, future expected loss experience, prepayment assumptions, and other factors. The resulting estimates involve uncertainties and are considered best estimates. Changes made to any of the underlying assumptions could significantly affect the estimates.

Cash and cash equivalents

The carrying value reported in the balance sheet for cash and cash equivalents approximates fair value due to the short-term nature of their maturities and are classified as Level 1.

Held-to-maturity investment securities

Held-to-maturity securities currently include mortgage-backed securities. The mortgage-backed securities are fixed income instruments that are not quoted on an exchange, but may be traded in active markets. The fair value of these securities is based on quoted market prices obtained from external pricing services. The principal market for our securities portfolio is the secondary institutional market, with an exit price that is predominantly reflective of bid level pricing in that market.Accordingly, held-to-maturity mortgage-backed securities are included in the Level 2 fair value category.

Loans held for sale

Loans held for sale are recorded at the lower of cost or fair value in the aggregate. Fair value estimates are based on actual commitments to sell the loans to investors at an agreed upon price or current market prices if rates have changed since the time the loan closed. Accordingly, loans held for sale are included in the Level 2 fair value category.

Loans, net

Fair value estimates are based on loans with similar financial characteristics. Fair values of commercial and residential mortgage loans are estimated by discounting contractual cash flows adjusted for prepayment estimates and using discount rates approximately equal to current market rates on loans with similar credit and interest rate characteristics and maturities. The fair value estimates for home equity and other loans are based on outstanding loan terms and pricing in the local markets. Net loans are included in the Level 3 fair value category based upon the inputs and valuation techniques used.

Other financial assets

Other financial assets consist of accrued interest and fees receivable, and stock in the Federal Home Loan Bank of Boston (“FHLB”) and the Federal Reserve Bank (“FRB”), for which the carrying amount approximates fair value, and are classified as Level 2.

Deposits

The fair values reported for transaction accounts (demand, NOW, savings, and money market) equal their respective book values reported on the balance sheet and are classified as Level 2. The fair values disclosed are, by definition, equal to the amount payable on demand at the reporting date. The fair values for certificates of deposit are based on the discounted value of contractual cash flows. The discount rates used are representative of approximate rates currently offered on certificates of deposit with similar remaining maturities and are classified as Level 2.

Securities sold under agreements to repurchase

The fair value of securities sold under agreements to repurchase is estimated based on contractual cash flows discounted at the Bank’s incremental borrowing rate for FHLB borrowings with similar maturities and have been classified as Level 2.

Federal funds purchased

The carrying amounts of federal funds purchased approximate fair value due to their short-term nature and therefore these funds have been classified as Level 2.

22

BOSTON PRIVATE FINANCIAL HOLDINGS, INC. AND SUBSIDIARIES

Notes to Unaudited Consolidated Financial Statements - (Continued)

Federal Home Loan Bank borrowings

The fair value reported for FHLB borrowings is estimated based on the discounted value of contractual cash flows. The discount rate used is based on the Bank’s estimated current incremental borrowing rate for FHLB borrowings of similar maturities and therefore these borrowings have been classified as Level 2.

Junior subordinated debentures

The fair value of the junior subordinated debentures issued by Boston Private Capital Trust I and Boston Private Capital Trust II were estimated using Level 3 inputs such as the interest rates on these securities, current rates for similar debt, a consideration for illiquidity of trading in the debt, and regulatory changes that would result in an unfavorable change in the regulatory capital treatment of this type of debt.

Other financial liabilities

Other financial liabilities consists of accrued interest payable for which the carrying amount approximates fair value and is classified as Level 2.

Financial instruments with off-balance sheet risk

The Bank’s commitments to originate loans and for unused lines and outstanding letters of credit are primarily at market interest rates and therefore, the carrying amount approximates fair value.

6.    Loan Portfolio and Credit Quality

The Bank’s lending activities are conducted principally in the regions of New England, the San Francisco Bay Area, and Southern California. The Bank originates single and multi-family residential loans, commercial real estate loans, commercial and industrial loans, commercial tax-exempt loans, construction and land loans, and home equity and other consumer loans. Most loans are secured by borrowers’ personal or business assets. The ability of the Bank’s single family residential and consumer borrowers to honor their repayment commitments is generally dependent on the level of overall economic conditions within the Bank’s lending areas. Commercial, construction, and land borrowers’ ability to repay is generally dependent upon the health of the economy and real estate values, including, in particular, the performance of the construction sector. Accordingly, the ultimate collectability of a substantial portion of the Bank’s loan portfolio is susceptible to changing conditions in the New England, the San Francisco Bay Area, and Southern California economies and real estate markets.

The following table presents a summary of the loan portfolio based on the portfolio segment as of the dates indicated:

The Bank’s policy is to discontinue the accrual of interest on a loan when the collectability of principal or interest is in doubt. In certain instances, although infrequent, loans that have become 90 days or more past due may remain on accrual status if the value of the collateral securing the loan is sufficient to cover principal and interest and the loan is in the process of collection. There were no loans 90 days or more past due, but still accruing as of both March 31, 2018 and December 31, 2017. The Bank’s policy for returning a loan to accrual status requires the loan to be brought current and for the client to show a history of making timely payments (generally six consecutive months). For troubled debt restructured loans (“TDRs”), a return to accrual status generally requires timely payments for a period of six months in accordance with the restructured loan terms, along with meeting other criteria.

The following tables show the payment status of loans receivable by class of receivable as of the dates indicated:

Nonaccrual and delinquent loans are affected by many factors, such as economic and business conditions, interest rates, unemployment levels, and real estate collateral values, among others. In periods of prolonged economic decline, borrowers may become more severely affected over time as liquidity levels decline and the borrower’s ability to continue to make payments deteriorates. With respect to real estate collateral values, the declines from the peak, as well as the value of the real estate at the time of origination versus the current value, can impact the level of problem loans. For instance, if the loan to value ratio at the time of renewal has increased due to the decline in the real estate value since origination, the loan may no longer meet the Bank’s underwriting standards and may be considered for classification as a problem loan dependent upon a review of risk factors.

Generally when a collateral dependent loan becomes impaired, an updated appraisal of the collateral, if appropriate, is obtained. If the impaired loan has not been upgraded to a performing status within a reasonable amount of time, the Bank will continue to obtain updated appraisals as deemed necessary, especially during periods of declining property values.

The past due status of a loan is determined in accordance with its contractual repayment terms. All loan types are reported past due when one scheduled payment is due and unpaid for 30 days or more.

Credit Quality Indicators

The Bank uses a risk rating system to monitor the credit quality of its loan portfolio. Loan classifications are assessments made by the Bank of the status of the loans based on the facts and circumstances known to the Bank, including management’s judgment, at the time of assessment. Some or all of these classifications may change in the future if there are unexpected changes in the financial condition of the borrower, including but not limited to, changes resulting from continuing deterioration in general economic conditions on a national basis or in the local markets in which the Bank operates adversely affecting, among other things, real estate values. Such conditions, as well as other factors which adversely affect borrowers’ ability to service or repay loans, typically result in changes in loan default and charge-off rates, and increased provisions for loan losses, which would adversely affect the Company’s financial performance and financial condition. These circumstances are not entirely foreseeable and, as a result, it may not be possible to accurately reflect them in the Company’s analysis of credit risk. Generally, only commercial loans, including commercial real estate, other commercial and industrial loans, commercial tax-exempt loans, and construction and land loans, are given a numerical grade.

A summary of the rating system used by the Bank, repeated here from Part II. Item 8. “Financial Statements and Supplementary Data - Note 1: Basis of Presentation and Summary of Significant Accounting Policies,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, follows:

Pass - All loans graded as pass are considered acceptable credit quality by the Bank and are grouped for purposes of calculating the allowance for loan losses. For residential, home equity and consumer loans, the Bank classifies loans as pass unless there is known information such as delinquency or client requests for modifications which, due to financial difficulty, would then generally result in a risk rating such as special mention or more severe depending on the factors.

Special Mention - Loans rated in this category are defined as having potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may, at some future date, result in the

25

BOSTON PRIVATE FINANCIAL HOLDINGS, INC. AND SUBSIDIARIES

Notes to Unaudited Consolidated Financial Statements - (Continued)

deterioration of the repayment prospects for the credit or the Bank’s credit position. These loans are currently protected but have the potential to deteriorate to a substandard rating. For commercial loans, the borrower’s financial performance may be inconsistent or below forecast, creating the possibility of liquidity problems and shrinking debt service coverage. In loans having this rating, the primary source of repayment is still good, but there is increasing reliance on collateral or guarantor support. Collectability of the loan is not yet in jeopardy. In particular, loans in this category are considered more variable than other categories, since they will typically migrate through categories more quickly.

Substandard - Loans rated in this category are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. A substandard credit has a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Substandard loans may be either still accruing or nonaccruing depending upon the severity of the risk and other factors such as the value of the collateral, if any, and past due status.

Doubtful - Loans rated in this category indicate that collection or liquidation in full on the basis of currently existing facts, conditions, and values, is highly questionable and improbable. Loans in this category are usually on nonaccrual and classified as impaired.

The following tables present the loan portfolio’s credit risk profile by internally assigned grade and class of receivable as of the dates indicated:

(1) Recorded investment represents the client loan balance net of historical charge-offs and historical nonaccrual interest paid, which was applied to principal.

When management determines that it is probable that the Bank will not collect all principal and interest on a loan in accordance with the original loan terms, the loan is designated as impaired.

Loans that are designated as impaired require an analysis to determine the amount of impairment, if any. Impairment would be indicated as a result of the carrying value of the loan exceeding the estimated collateral value, less costs to sell, for collateral dependent loans or the net present value of the projected cash flow, discounted at the loan’s contractual effective interest rate, for loans not considered to be collateral dependent. Generally, shortfalls in the analysis on collateral dependent loans would result in the impairment amount being charged-off to the allowance for loan losses. Shortfalls on cash flow dependent loans may be carried as specific allocations to the general reserve unless a known loss is determined to have occurred, in which case such known loss is charged-off.

Loans in the held for sale category are carried at the lower of amortized cost or estimated fair value in the aggregate and are excluded from the allowance for loan losses analysis.

The Bank may, under certain circumstances, restructure loans as a concession to borrowers who are experiencing financial difficulty. Such loans are classified as TDRs and are included in impaired loans. TDRs typically result from the Bank’s loss mitigation activities which, among other things, could include rate reductions, payment extensions, and/or principal

Notes to Unaudited Consolidated Financial Statements - (Continued)

forgiveness. As of March 31, 2018 and December 31, 2017, TDRs totaled $13.2 million and $13.6 million, respectively. As of March 31, 2018, $10.9 million of the $13.2 million in TDRs were on accrual status. As of December 31, 2017, $11.1 million of the $13.6 million in TDRs were on accrual status.

Since all TDR loans are considered impaired loans, they are individually evaluated for impairment. The resulting impairment, if any, would have an impact on the allowance for loan losses as a specific reserve or charge-off. If, prior to the classification as a TDR, the loan was not impaired, there would have been a general or allocated reserve on the particular loan. Therefore, depending upon the result of the impairment analysis, there could be an increase or decrease in the related allowance for loan losses. Many loans initially categorized as TDRs are already on nonaccrual status and are already considered impaired. Therefore, there is generally not a material change to the allowance for loan losses when a nonaccruing loan is categorized as a TDR. There were no loans that were restructured or defaulted during the three months ended March 31, 2018 or 2017.

Loan participations serviced for others and loans serviced for others are not included in the Company’s total loans. The following table presents a summary of the loan participations serviced for others and loans serviced for others based on class of receivable as of the dates indicated:

The allowance for loan losses is an estimate of the inherent risk of loss in the loan portfolio as of the consolidated balance sheet dates. Management estimates the level of the allowance based on all relevant information available. Changes to the required level in the allowance result in either a provision for loan loss expense, if an increase is required, or a credit to the provision, if a decrease is required. Loan losses are charged to the allowance when available information confirms that specific loans, or portions thereof, are uncollectible. Recoveries on loans previously charged-off are credited to the allowance when received in cash.

The provision/ (credit) for loan losses and related balance in the allowance for loan losses for tax-exempt commercial and industrial loans are included with commercial and industrial. The provision/ (credit) for loan losses and related balance in the allowance for loan losses for tax-exempt commercial real estate loans are included with commercial real estate. There were no charge-offs or recoveries, for any period presented, for both commercial and industrial and commercial real estate tax-exempt loans.

8.    Derivatives and Hedging Activities

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and, to a lesser extent, the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are generally determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to certain loans, deposits, and borrowings. As a service to its customers, the Company may utilize

derivative instruments including customer foreign exchange forward contracts to manage its foreign exchange risk, if any.

(1) There was an additional $(4) thousand loss related to the ineffective portion for the three months ended as of March 31, 2017. The guidance in ASU 2017-12 requires that amounts in accumulated other comprehensive income that are included in the assessment of effectiveness should be reclassified into earnings in the same period in which the hedged forecasted transactions impact earnings. Transition guidance for this ASU further states that upon adoption, previously recorded cumulative ineffectiveness for cash flow hedges existing at the adoption date be eliminated by means of a cumulative-effect adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the initial application date. There was a $5 thousand reclassification related to the adoption of ASU 2017-12 effective January 1, 2018.

The Bank has agreements with its derivative counterparties that contain provisions where, if the Bank defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Bank could also be declared in default on its derivative obligations. The Bank was in compliance with these provisions as of March 31, 2018 and December 31, 2017.

The Bank also has agreements with certain of its derivative counterparties that contain provisions where, if the Bank fails to maintain its status as a well- or adequately-capitalized institution, then the counterparty could terminate the derivative positions and the Bank would be required to settle its obligations under the agreements. The Bank was in compliance with these provisions as of March 31, 2018 and December 31, 2017.

Certain of the Bank’s agreements with its derivative counterparties contain provisions where, if specified, events or conditions occur that materially change the Bank’s creditworthiness in an adverse manner, the Bank may be required to fully collateralize its obligations under the derivative instruments. The Bank was in compliance with these provisions as of March 31, 2018 and December 31, 2017.

As of March 31, 2018 there were no termination amounts related to collateral determinations of derivatives in a liability position and as of December 31, 2017, the termination amount was $3.1 million. The Company has minimum collateral posting thresholds with its derivative counterparties and pledged securities with market values of $2.2 million and $2.3 million, respectively, as of March 31, 2018 and December 31, 2017, against its obligations under these agreements. The collateral posted is typically greater than the current liability position; however, due to timing of liability position changes at period end, the funding of a collateral shortfall may take place shortly following period end.

Cash Flow Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company has entered into interest rate swaps as part of its interest rate risk management strategy.  These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed payments.  The Company has entered into interest rate swaps to hedge London Interbank Offered Rate (“LIBOR”) -indexed brokered deposits and the LIBOR component of the total cost of certain FHLB borrowings.

To accomplish this objective and strategy, the Bank has entered into a total of six interest rate swaps, two during 2017 with effective dates of March 22, 2017 and four during 2013 with effective dates of September 2, 2014, June 1, 2014, March 1, 2014, and August 1, 2013.

The two interest rate swaps entered into during 2017 have notional amounts of $40 million and $60 million with terms of 1.75 and 2.25 years, respectively. These interest rate swaps will effectively fix the Bank’s interest payments on $100 million in interest-related cash outflows attributable to changes in the LIBOR component of FHLB borrowing liabilities at rates of 1.55% and 1.65%, respectively, with a weighted average rate of 1.61%. The borrowings hedged will initially be expected to be issuances and quarterly rollovers of three-month FHLB advances but may also then include future issuances of three-month repurchase agreements with similar characteristics and/or future issuances of either floating or fixed rate borrowings that are issued with the specific intent to replace the quarterly rollovers of the advances or repurchase agreements.

34

BOSTON PRIVATE FINANCIAL HOLDINGS, INC. AND SUBSIDIARIES

Notes to Unaudited Consolidated Financial Statements - (Continued)

The four interest rate swaps entered into during 2013 each have a notional amount of $25 million and have terms ranging from four to six years from their respective effective dates. The interest rate swaps effectively fix the Bank’s interest payments on $125 million of its LIBOR-indexed deposit liabilities at rates between 1.68% and 2.32%, with a weighted average rate of 1.95%.

Prior to the implementation of ASU 2017-12, which was implemented on a modified retrospective basis on January 1, 2018, the Company used the “Hypothetical Derivative Method” described in ASC 815, Derivatives and Hedging (“ASC 815”), for quarterly prospective and retrospective assessments of hedge effectiveness, as well as for measurements of hedge ineffectiveness. Under this method, the Company assessed the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged transactions. The effective portion of changes in the fair value of the derivative was initially reported in other comprehensive income (“OCI”) (outside of earnings) and subsequently reclassified to earnings in interest and dividend income when the hedged transactions affect earnings. Ineffectiveness resulting from the hedge was recorded as a gain or loss in the consolidated statement of operations as part of fees and other income.

Upon implementation of ASU 2017-12, for derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income and subsequently reclassified into interest expense in the same period during which the hedged transaction affects earnings. A portion of the balance reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made or received on the Company’s interest rate swaps. During the next twelve months, the Company estimates that $1.1 million will be reclassified as a decrease in interest expense. The Company monitors the risk of counterparty default on an ongoing basis.

Non-designated Hedges

Derivatives not designated as hedges are not speculative and result from different services the Bank provides to qualified commercial clients. The Bank offers certain derivative products directly to such clients. The Bank economically hedges derivative transactions executed with commercial clients by entering into mirror-image, offsetting derivatives with third parties. Derivative transactions executed as part of these programs are not designated in ASC 815-qualifying hedging relationships and are, therefore, marked-to-market through earnings each period. Because the derivatives have mirror-image contractual terms, the changes in fair value substantially offset through earnings. The net effect on earnings is primarily driven by changes in the credit valuation adjustment (“CVA”). The CVA represents the dollar amount of fair value adjustment related to nonperformance risk of both the Bank and its counterparties. Fees earned in connection with the execution of derivatives related to this program are recognized in the consolidated statement of operations in other income. As of March 31, 2018 and December 31, 2017, the Bank had 148 and 142 derivatives, respectively, related to this program, comprised of interest rate swaps and caps, with an aggregate notional amount of $1.2 billion as of March 31, 2018 and $1.1 billion as of December 31, 2017. As of March 31, 2018, there were four foreign currency exchange contracts with an aggregate notional amount of $0.3 million outstanding related to this program, and as of December 31, 2017, there were three foreign currency exchange contracts with an aggregate notional amount of $0.2 million.

In addition, as a participant lender, the Bank has guaranteed performance on the pro-rated portion of swaps executed by other financial institutions. As the participant lender, the Bank is providing a partial guarantee, but is not a direct party to the related swap transactions. The Bank has no obligations under the risk participation agreements unless the borrower defaults on their swap transaction with the lead bank and the swap is in a liability position to the borrower. In that instance, the Bank has agreed to pay the lead bank a portion of the swap’s termination value at the time of the default. The derivative transactions entered into as part of these agreements are not designated, as per ASC 815, as qualifying hedging relationships and are, therefore, marked-to-market through earnings each period. As of March 31, 2018, there were seven of these risk participation transactions with an aggregate notional amount of $60.3 million and, as of December 31, 2017, there were six of these risk participation transactions with an aggregate notional amount of $48.0 million.

The Bank has also participated out to another financial institution a pro-rated portion of two swaps executed by the Bank. The other financial institution has no obligations under the risk participation agreements unless the borrowers default on their swap transactions with the Bank and the swaps are in liability positions to the borrower. In those instances, the other financial institution has agreed to pay the Bank a portion of the swap’s termination value at the time of the default. The derivative transactions entered into as part of these agreements are not designated, as per ASC 815, as qualifying hedging relationships and are, therefore, marked-to-market through earnings each period. The pro-rated notional amount of these risk participation transactions was $6.1 million as of both March 31, 2018 and December 31, 2017.

The following table presents the effect of the Bank’s derivative financial instruments not designated as hedging instruments in the consolidated statement of operations for the three months ended March 31, 2018 and 2017.

The following table presents the components of income tax expense for continuing operations, discontinued operations, noncontrolling interests and the Company:

Net income attributable to the Company	$	22,686		$	15,662
Effective tax rate attributable to the Company	22.8		%	33.0		%

The effective tax rate for continuing operations for the three months ended March 31, 2018 of 21.5%, with related tax expense of $6.0 million, was calculated based on a projected 2018 annual effective tax rate. The effective tax rate was more than the statutory rate of 21% due primarily to state and local income taxes and the accounting for investments in affordable housing projects. These items were partially offset by earnings from tax-exempt investments, income tax credits, and income attributable to noncontrolling interests.

The effective tax rate for continuing operations for the three months ended March 31, 2017 of 30.4%, with related tax expense of $6.6 million, was calculated based on a projected 2017 annual effective tax rate. The effective tax rate was less

36

Notes to Unaudited Consolidated Financial Statements - (Continued)

than the statutory rate of 35% due primarily to earnings from tax-exempt investments, income tax credits, and income attributable to noncontrolling interests. These items were partially offset by state and local income taxes.

The effective tax rate for continuing operations for the three months ended March 31, 2018 is lower than the effective tax rate for the same period in 2017 due primarily to the reduction in the federal corporate tax rate from 35% to 21% as a result of the Tax Cuts and Jobs Act (the “Tax Act”) that was enacted on December 22, 2017.

10.    Noncontrolling Interests

At the Company, noncontrolling interests consist of equity owned by management of the Company’s respective majority-owned affiliates. Net income attributable to noncontrolling interests in the consolidated statements of operations represents the net income allocated to the noncontrolling interest owners of the affiliates. Net income allocated to the noncontrolling interest owners was $1.1 million and $1.0 million for the three-month periods ended March 31, 2018 and 2017, respectively.

On the consolidated balance sheets, noncontrolling interests are included as the sum of the capital and undistributed profits allocated to the noncontrolling interest owners. Typically, this balance is included in a company’s permanent shareholders’ equity in the consolidated balance sheets. When the noncontrolling interest owners’ rights include certain redemption features, as described in ASC 480, Distinguishing Liabilities from Equity, such redeemable noncontrolling interests are classified as mezzanine equity and are not included in permanent shareholders’ equity. Due to the redemption features of the noncontrolling interests, the Company had redeemable noncontrolling interests held in mezzanine equity in the accompanying consolidated balance sheets of $16.3 million and $17.5 million at March 31, 2018 and December 31, 2017, respectively. The aggregate amount of such redeemable noncontrolling equity interests are recorded at the estimated maximum redemption values. In addition, the Company had $4.8 million and $5.2 million in noncontrolling interests included in permanent shareholder’s equity at March 31, 2018 and December 31, 2017, respectively.

Each non-wholly owned affiliate operating agreement provides the Company and/or the noncontrolling interests with contingent call or put redemption features used for the orderly transfer of noncontrolling equity interests between the affiliate noncontrolling interest owners and the Company at either a contractually predetermined fair value; multiple of earnings before interest, taxes, depreciation, and amortization (EBITDA); or fair value. The Company may liquidate these noncontrolling interests in cash, shares of the Company’s common stock, or other forms of consideration dependent on the operating agreement. These agreements are discussed in Part II. Item 8. “Financial Statements and Supplementary Data - Note 14: Noncontrolling Interests” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Generally, these put and call redemption features refer to shareholder rights of both the Company and the noncontrolling interest owners of the Company’s majority-owned affiliate companies. The affiliate company noncontrolling interests generally take the form of limited liability company (LLC) units, profits interests, or common stock (collectively, the “noncontrolling equity interests”). In most circumstances, the put and call redemption features generally relate to the Company’s right and, in some cases, obligation to purchase and the noncontrolling equity interests’ right to sell their equity interests. There are various events that could cause the puts or calls to be exercised, such as a change in control, death, disability, retirement, resignation or termination. The puts and calls are generally to be exercised at the then fair value or a contractually agreed upon approximation thereof. The terms of these rights vary and are governed by the respective individual operating and legal documents.

The following table presents, by affiliate, the noncontrolling interests included as redeemable noncontrolling interests and noncontrolling interests in mezzanine and permanent equity, respectively, at the periods indicated:

On January 1, 2018, the Company adopted ASU No. 2016-01. As a result, the Company reclassified unrealized gains on equity securities available-for-sale, net of tax, of $339 thousand from accumulated other comprehensive income/ (loss) to beginning retained earnings.

12.    Restructuring

In the fourth quarter of 2014, the Company incurred restructuring charges related to the acquisition of Banyan Partners, LLC. The purpose of this restructuring was to realign the management structure within the Wealth Management and Trust segment. The total cost of the restructuring incurred in Q4 2014 was $0.7 million. In 2015, the Company incurred additional restructuring charges to further refine the management structure within the Wealth Management and Trust segment. The total cost of the restructuring charges in 2015 was $3.7 million.

In the first and second quarters of 2016, the Company incurred additional costs of $1.1 million and $0.9 million, respectively, in continued refinement of the management structure within the Wealth Management and Trust segment. The Company does not anticipate any additional restructuring costs related to this plan as of the date of this filing.

Restructuring expenses incurred since the plan of restructuring was first implemented in 2014 totaled $6.4 million, all within the Wealth Management and Trust segment.

The following table presents a summary of the restructuring activity for the three months ended March 31, 2018 and 2017:

13.    Revenue Recognition

On January 1, 2018, the Company adopted ASU 2014-09 et al. As stated in Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 1: Basis of Presentation and Summary of Significant Accounting Policies,” the implementation of the new standard did not have a material impact on the measurement or recognition of revenue; as such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, Revenue from Contracts with Customers (“ASC 606”), while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting under ASC 605, Revenue Recognition.

ASC 606 does not apply to revenue associated with financial instruments, including interest income on loans and investment securities. In addition, certain noninterest income such as fees associated with mortgage servicing rights, late fees, BOLI income, and derivatives are also not in scope of the new guidance. ASC 606 is applicable to noninterest income such as investment management fees, wealth advisory fees, wealth management and trust fees, and certain banking fees. However, the recognition of this revenue did not change upon adoption of ASC 606. Substantially all of the Company’s revenue is generated from contracts with customers. Noninterest income considered in-scope of ASC 606 is discussed below.

Investment management fees

Investment management fees are earned for the management of a series of accounts and funds in which clients invest directly, acting as a sub-advisor to larger investment management companies, or private client account management. The Company’s performance obligation is satisfied over time and the resulting fees are recognized monthly, based upon either the beginning-of quarter (in advance) or quarter-end (in arrears) market value of the assets under management and the applicable fee rate, depending on the terms of the contract. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company may earn performance-based incentives on certain contracts. Receivables are recorded on the consolidated balance sheet in the fees receivable line item.

All of the investment management fee income on the consolidated statement of operations for the three months ended March 31, 2018 is considered in-scope of ASC 606.

40

BOSTON PRIVATE FINANCIAL HOLDINGS, INC. AND SUBSIDIARIES

Notes to Unaudited Consolidated Financial Statements - (Continued)

Wealth advisory fees

Wealth advisory fees are earned for providing financial advisory services to clients. The Company’s performance obligation under these contracts is satisfied over time as the financial advisory services are provided. Fees are recognized monthly based either on a fixed fee amount or are based on the quarter-end (in arrears) market value of the assets under management and the applicable fee rate (“asset based fees”), depending on the terms of the contract. Payment on fixed fee contracts is received based on a schedule outlined in the contract, while payment on asset based fees are generally received a few days after quarter end through a direct charge to customers’ accounts. No performance based incentives are earned on wealth advisory contracts. Receivables are recorded on the consolidated balance sheet in the fees receivable line item. Deferred revenues related to the fixed fee contracts of $6.2 million and $6.6 million at March 31, 2018 and December 31, 2017, respectively, are recorded on the consolidated balance sheet within the other liabilities line item.

All of the wealth advisory fee income on the consolidated statement of operations for the three months ended March 31, 2018 is considered in-scope of ASC 606.

Wealth management and trust fees

Wealth management fees are earned for providing investment management, retirement plan advisory, family office, and financial planning services to clients. The Company’s performance obligation under these contracts is satisfied over time as the wealth management services are provided. Fees are recognized monthly based on the average monthly, beginning-of-quarter, or, for a small number of clients, end-of-quarter market value of the assets under management and the applicable fee rate, depending on the terms of the contract. No performance based incentives are earned on wealth management contracts. Receivables are recorded on the consolidated balance sheet in the fees receivable line item.

Trust fees are earned when the Company is appointed as trustee for clients. As trustee, the Company administers the client’s trust and manages the assets of the trust including investments and property. The Company’s performance obligation under these agreements is satisfied over time as the administration and management services are provided. Fees are recognized monthly based on a percentage of the market value of the account as outlined in the agreement. Payment frequency is defined in the individual contracts which primarily stipulate monthly in arrears. No performance based incentives are earned on trust fee contracts. Receivables are recorded on the consolidated balance sheet in the fees receivable line item.

All of the wealth management and trust fee income on the consolidated statement of operations for the three months ended March 31, 2018 is considered in-scope of ASC 606.

Other banking fee income

The Bank charges a variety of fees to its clients for services provided on the deposit and deposit management related accounts. Each fee is either transaction-based or assessed monthly. The types of fees include service charges on accounts, overdraft fees, maintenance fees, ATM fee charges, credit card charges, and other miscellaneous charges related to the accounts. These fees are not governed by individual contracts with clients. They are charges to clients based on disclosures presented to clients upon opening these accounts along with updated disclosures when changes are made to the fee structures. The transaction-based fees are recognized in revenue when charged to the client based on specific activity on the client’s account. Monthly service/maintenance charges are recognized in the month they are earned and are charged directly to the client’s account.

The Bank also charges fees for treasury activities such as foreign exchange fees for clients with a banking relationship. These fees are recorded when earned via completion of the transaction for the client. The completion of the transaction is deemed to be the performance obligation of the transaction. The related revenue is recorded through a direct charge to the client’s account. There are no individual agreements or contracts with clients as it relates to foreign exchange fees as they are governed by client disclosure statements and the Bank’s internal policies and procedures.

For both three month periods ended March 31, 2018 and 2017, $0.9 million of other banking fee income as described above is considered in-scope for ASC 606.

14.    Recent Accounting Pronouncements

In May 2014 and at various other dates after May 14, the FASB issued ASU 2014-09 et al. Under the new standard, a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. ASU 2014-09 et al. does not apply to revenue associated with financial instruments such as loans and securities. On January 1, 2018, we adopted ASU 2014-09 et al. using the modified retrospective transition method, however no cumulative effect adjustment to opening retained

BOSTON PRIVATE FINANCIAL HOLDINGS, INC. AND SUBSIDIARIES

Notes to Unaudited Consolidated Financial Statements - (Continued)

earnings as of January 1, 2018 was required. For additional disclosure details, see Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 1: Basis of Presentation and Summary of Significant Accounting Policies and Note 13: Revenue Recognition.”

In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Instruments - Going Concern (“ASU 2014-15”). ASU 2014-15 requires management to evaluate an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Management must evaluate whether conditions and events raise substantial doubt about an entity’s ability to continue as a going concern and then whether its plans alleviate that doubt. ASU 2014-15 was effective in 2016 and management performed the required evaluation and concluded that there were no such conditions or events that raised substantial doubt about the Company’s ability to continue as a going concern.

In January 2016, the FASB issued ASU 2016-01. This ASU requires equity investments to be measured at fair value with changes in fair value, net of tax, recognized in net income. As a result of implementing this standard, the Company reclassified $339 thousand in unrealized gains on available-for-sale equity investments, net of tax, from accumulated other comprehensive income to retained earnings as of January 1, 2018.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This ASU update amends current lease accounting and requires all leases, other than short-term leases, to be reported on the balance sheet through the recognition of a right-of-use asset and a corresponding liability for future lease obligations. The amended guidance will be effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods and will require transition utilizing a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption of this ASU is permitted although the Company does not plan to early adopt. The Company does not anticipate a material impact to revenue or operating expenses as a result of the adoption of this ASU. The Company expects that this ASU will gross up the assets and liabilities on the balance sheet related to the lease assets and liabilities and reduce regulatory capital ratios.

In March 2016, the FASB issued ASU 2016-09, Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This update is intended to simplify several aspects of the accounting for employee share-based plans such as income tax consequences, classification of awards as either liabilities or equity on the balance sheet, and classification on the statement of cash flows. This ASU was effective for fiscal years beginning after December 15, 2016, including interim periods within those years. The Company adopted this ASU on January 1, 2017. The adoption of this ASU has resulted in, and will continue to result in, fluctuations in the Company’s earnings due to changes in the Company’s stock price between issuance date and settlement date of employee share-based transactions. In addition, the Company anticipates that certain stock options will expire unexercised, due to being out of the money, and this ASU requires the previous tax benefits to be reversed.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments (Topic 326) (“ASU 2016-13”). This update is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This ASU will be effective for fiscal years beginning after December 15, 2019. Early adoption is available as of the fiscal year beginning after December 15, 2018. The Company does not plan on adopting early. The impact of this ASU on the Company’s consolidated financial statements will depend on factors at the time of adoption such as the balance and type of loans on the balance sheet, the Company’s loan loss history, and various qualitative factors.

In August 2016, the FASB issued ASU 2016-15.  This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. This ASU is effective for the Company beginning on January 1, 2018. Early adoption was permitted, provided that all of the amendments are adopted in the same period, however the Company did not early adopt. The guidance requires application using a retrospective transition method. This ASU did not have an impact on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU 2017-07. This amendment requires an employer to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. As a result of the adoption of this ASU, $160 thousand has been reclassified from salaries and employee benefits expense to other expense within the Company’s consolidated statement of operations for the three months ended March 31, 2017. For the three months ended

42

BOSTON PRIVATE FINANCIAL HOLDINGS, INC. AND SUBSIDIARIES

Notes to Unaudited Consolidated Financial Statements - (Continued)

March 31, 2018, $135 thousand is presented within other expense that would have been presented within salaries and employee benefits prior to adoption of ASU 2017-07.

In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities (“ASU 2017-08”). This update amends the amortization period for certain purchased callable debt securities held at a premium. The amortization period for the premium on such securities is being shortened to the earliest call date. Under current GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument. ASU 2017-08 is effective for fiscal years beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, including in an interim period. The guidance requires application using a modified retrospective transition method through a cumulative-effect adjustment to beginning retained earnings. The Company early adopted this ASU as of July 1, 2017, which had a minimal impact on the consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12. The standard is intended to improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities by better aligning the entity’s financial reporting for hedging relationships with those risk management activities and to reduce the complexity of and simplify the application of hedge accounting by preparers. ASU No. 2017-12 is effective for interim and annual reporting periods beginning after December 15, 2018; early adoption is permitted. The Company elected to early adopt this ASU as of January 1, 2018 with a modified retrospective transition. As a result of implementing this standard, the Company reclassified $5 thousand in unrealized losses on derivatives from accumulated other comprehensive income to retained earnings as of January 1, 2018. This ASU will provide more flexibility in the Company’s risk management activities and we believe it will enhance the Company’s ability to employ risk management strategies, while improving the transparency and understanding of those strategies for financial statement users.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This update was issued to address a narrow-scope financial reporting issue that arose as a consequence of the change in the tax law. On December 22, 2017, the U.S. federal government enacted the Tax Act which, among other significant changes, lowers the federal corporate tax rate from 35% to 21% effective January 1, 2018. This update requires a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the enactment of the Tax Act. ASC 740 requires that the tax effects of changes in tax rates be recognized in income tax expense/ (benefit) attributable to continuing operations in the period in which the law is enacted. As a result, the tax effect of accumulated other comprehensive income does not reflect the appropriate tax rate. The amendments in this ASU eliminate the stranded tax effects associated with the change in the federal corporate income tax rate related to the Tax Act and improve the usefulness of information reported to financial statement users. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those years. Early adoption is permitted for public business entities for reporting periods for which financial statements have not yet been issued. The Company early adopted this ASU on December 31, 2017 and reclassified $1.5 million from accumulated other comprehensive income to retained earnings.

15.    Subsequent Event

In April 2018, the Company completed the sale of its ownership interest in Anchor. Anchor’s results remain consolidated in the Company’s results during current and prior periods. The transaction had previously been announced in December 2017. The Company classified the assets and liabilities of Anchor as held for sale at March 31, 2018 and December 31, 2017, which are included with other assets and other liabilities, respectively, on the Company’s consolidated balance sheets.

As a result of the transaction, Boston Private received approximately $32 million of cash and will receive future revenue share payments that have a net present value of approximately $15 million. During the second quarter, the Company will recognize a tax expense of approximately $11 million to $12 million attributable to the transaction, which is primarily the result of a book to tax basis difference associated with nondeductible goodwill. The net financial impact will increase the Company’s Tier 1 common equity by approximately $34 million to $35 million. Accordingly, the results of Anchor after the completion of the sale in April 2018 will not be included in the results of the Company.

(1) Includes the assets under management at Anchor of $9.0 billion and $9.1 billion at March 31, 2018 and 2017, respectively.

Net income attributable to the Company was $22.7 million for the three months ended March 31, 2018 and $15.7 million for the same period in 2017. The Company recognized diluted earnings per share of $0.27 and $0.17 for the three-month periods ended March 31, 2018 and 2017, respectively.

Key items that affected the Company’s results in the first quarter of 2018 compared to the same period of 2017 include:

▪ Net interest income increased 7%, to $57.4 million for the three months ended March 31, 2018, compared to $53.6 million for the same period of 2017. The increase for the three months is due to higher volume and yields on loans and higher yield on investments, partially offset by higher volumes and average rates paid on interest-bearing deposits and the Company’s borrowings as well as lower volume of investments. The net interest margin (“NIM”) was 2.95% for the three months ended March 31, 2018, an increase of one basis point compared to the same period in 2017.

▪ Total fees and other income increased 9% to $39.7 million for the three months ended March 31, 2018, compared to $36.5 million for the same period of 2017. This increase was driven by a 12% increase in wealth management and trust fees, a 5% increase in both investment management fees and wealth advisory fees, and a 34% increase in other banking fee income related to swap fee and BOLI income. Total fees and other income represents 41% of total revenue for the three months ended March 31, 2018, compared to 40% of total revenue for the same period of 2017.

45

▪ Total operating expenses increased 3% to $70.9 million for the three months ended March 31, 2018, compared to $68.8 million for the same period of 2017. Increases in salaries and employee benefits, occupancy and equipment, and information systems were partially offset by decreases in amortization of intangibles and professional fees.

▪ Income tax expense decreased 8% to $6.0 million for the three months ended March 31, 2018, compared to $6.6 million for the same period of 2017. The decrease was primarily due to the reduction in the federal corporate tax rate from 35% to 21% as a result of the Tax Act that was enacted on December 22, 2017, partially offset by the increase in pre-tax earnings. 

The Company’s Private Banking segment reported net income attributable to the Company of $18.2 million in the first quarter of 2018, compared to net income attributable to the Company of $14.9 million for the same period of 2017. The $3.2 million, or 22%, increase was a result of an increase in net interest income, a larger credit to the provision for loan losses, and a decrease in income tax expense, partially offset by an increase in operating expenses. The increase in operating expenses was driven by salaries and employee benefits, occupancy and equipment, and information systems expenses. The decrease in income tax expense was primarily due to the reduction in the federal corporate tax rate. 

The Company’s Wealth Management and Trust segment reported net income attributable to the Company of $1.1 million in the first quarter of 2018, compared to a net loss attributable to the Company of $1.8 million for the same period of 2017. The change was due to a 23% decrease in operating expenses and a 12% increase in wealth management and trust fees, partially offset by income tax expense. The decrease in operating expense primarily related to decreases in salaries and employee benefits. The decrease in the effective income tax rate was primarily due to the reduction in the federal corporate tax rate. Fee-based revenue in the Wealth Management and Trust segment is determined based on average monthly, beginning-of-quarter, or, for a small number of clients, end-of-quarter AUM balances, depending on the custodian. Wealth Management and Trust AUM increased $0.6 billion, or 8%, to $7.8 billion at March 31, 2018 from $7.3 billion at March 31, 2017. The increase in AUM is due to net inflows of $0.3 billion and positive market action of $0.2 billion for the twelve months ending March 31, 2018.

The Company’s Investment Management segment reported net income attributable to the Company of $1.7 million in the first quarter of 2018, compared to net income attributable to the Company of $1.2 million for the same period of 2017. The 44% increase was due primarily to lower amortization of intangibles and depreciation expenses due to Anchor being classified as held for sale during the first quarter of 2018, as well as a 5% increase in investment management fee income and a 20% decrease in allocated income tax expense. These changes were partially offset by a $0.4 million trade error, and higher legal fees related to the Anchor transaction, and higher recruiting fees. The decrease in income tax expense was primarily due to the reduction in the federal corporate tax rate. Most fee-based revenue in the investment management segment is determined based on beginning-of-period AUM balances. Investment Management AUM, including both DGHM and Anchor, increased $0.1 billion, or 1%, to $11.0 billion at March 31, 2018 from $10.9 billion at March 31, 2017, due to positive market action of $0.8 billion, partially offset by net outflows of $0.7 billion for the twelve months ending March 31, 2018.

The sale of Anchor was completed in April 2018. While the results of Anchor while it was an affiliate of the Company will continue to be reported in the Company’s continuing operations, results for the remaining period of 2018 will not include Anchor operations following the transaction close in mid-April. For the three months ended March 31, 2018, Anchor represented 74% of segment total revenues, 75% of segment total operating expense, 70% of segment net income attributable to the Company, and 82% of segment assets under management. For the three months ended March 31, 2017, Anchor represented 74% of segment total revenues, 76% of segment total operating expense, 69% of segment net income attributable to the Company, and 83% of segment assets under management.

The Company’s Wealth Advisory segment reported net income attributable to the Company of $1.7 million in the first quarter of 2018, compared to net income attributable to the Company of $1.6 million for the same period of 2017. The 5% increase was due to a 5% increase in wealth advisory fee income and a 39% decrease in allocated income tax expense, partially offset by a 12% increase in operating expenses. Fee-based revenue in the Wealth Advisory segment is determined based on either a fixed fee or end-of-quarter AUM balances. The operating expense increase was primarily due to additional performance bonus accruals. The decrease in income tax expense was primarily due to the reduction in the federal corporate tax rate. Wealth Advisory AUM increased $0.9 billion, or 8%, to $11.4 billion at March 31, 2018 from $10.6 billion at March 31, 2017, primarily due to positive market action of $0.9 billion and flat net inflows for the twelve months ending March 31, 2018.

Critical Accounting Policies

Critical accounting policies reflect significant judgments and uncertainties, and could potentially result in materially different results under different assumptions and conditions. The Company believes that its most critical accounting policies

46

upon which its financial condition depends, and which involve the most complex or subjective decisions or assessments are the allowance for loan and lease losses, the valuation of goodwill and intangible assets and analysis for impairment, and tax estimates. These policies are discussed in Part II. Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. There have been no changes to these policies through the filing of this Quarterly Report on Form 10-Q.

Results of operations for the three months ended March 31, 2018 versus March 31, 2017

Net Income. The Company recorded net income from continuing operations for the three months ended March 31, 2018 of $22.0 million, compared to $15.0 million for the same period in 2017. Net income attributable to the Company, which includes income from both continuing and discontinued operations, for the three months ended March 31, 2018 was $22.7 million, compared to $15.7 million for the same period in 2017.

The Company recognized diluted EPS attributable to common shareholders, which includes both continuing and discontinued operations, for the three months ended March 31, 2018 of $0.27 per share, compared to $0.17 per share for the same period in 2017. Net income from continuing operations in both 2018 and 2017 was partially offset by charges that reduce income available to common shareholders. See Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 2: Earnings Per Share” for further detail on these charges to income available to common shareholders.

The following discussions are based on the Company’s continuing operations, unless otherwise stated.

The following table presents selected financial highlights:

Net interest income. Net interest income represents the difference between interest earned, primarily on loans and investments, and interest paid on funding sources, primarily deposits and borrowings. Interest rate spread is the difference between the average rate earned on total interest-earning assets and the average rate paid on total interest-bearing liabilities. NIM is the amount of net interest income, on a fully taxable-equivalent (“FTE”) basis, expressed as a percentage of average interest-earning assets. The average rate earned on earning assets is the amount of annualized taxable equivalent interest income expressed as a percentage of average earning assets. The average rate paid on interest-bearing liabilities is equal to annualized interest expense as a percentage of average interest-bearing liabilities. When credit quality declines and loans are placed on nonaccrual status, NIM can decrease because the same assets are earning less income. Loans graded as substandard but still accruing interest income totaled $45.2 million at March 31, 2018 and could be placed on nonaccrual status if their credit quality declines further.

47

Net interest income for the three months ended March 31, 2018 was $57.4 million, an increase of $3.7 million, or 7%, compared to the same period in 2017. The increase for the three-month period is due to higher yields and volume on loans and higher yields on cash and investments, partially offset by higher volume and average rates paid on the Company’s borrowings and interest-bearing deposits, lower volume on cash and investments, and higher rates paid on the Company’s junior subordinated debentures. The NIM was 2.95% for the three months ended March 31, 2018, an increase of one basis point compared to the same period in 2017. Due to the lower federal tax rate in 2018, the FTE adjustment has a lower impact on the interest gross-up for NIM purposes. The estimated impact on NIM due to the lower tax rate in 2018 is 10 basis points.

The following tables present the composition of the Company’s NIM on a FTE basis for the three months endedMarch 31, 2018 and 2017; however, the discussion following these tables reflects non-FTE data.

(1) Investments classified as available-for-sale and held-to-maturity are shown in the average balance sheet at amortized cost.

(2) Interest income on non-taxable investments and loans is presented on a FTE basis using statutory rates. The discussion following these tables reflects non-FTE data.

(3) Includes loans held for sale and nonaccrual loans.

Interest and dividend income. Total interest and dividend income for the three months ended March 31, 2018was $68.4 million, an increase of $7.3 million, or 12%, compared to the same period in 2017. The increase for the three months was primarily due to higher yields and volume on loans and higher yields on cash and investments, partially offset by lower volume of cash and investments.

The Bank generally has interest income that is either collected or reversed related to nonaccrual loans each quarter. Based on the net amount collected or reversed, the impact on interest income and related yields can be either positive or negative. In addition, the Bank collects prepayment penalties on certain commercial loans that pay off prior to maturity which could also impact interest income and related yields positively. The amount and timing of prepayment penalties varies from quarter to quarter.

Interest income on commercial and industrial loans, on a non-FTE basis, for the three months ended March 31, 2018was $8.5 million, an increase of $0.4 million, or 5%, compared to the same period in 2017, as a result of a 36 basis point increase in the average yield on a non-FTE basis, partially offset by a 5% decrease in the average balance. The increase in the average yield for the three-month period is the result of market conditions and the fluctuations in the indicies to which the variable rate loans are tied. The decrease in the average balance for the three-month period is related to a few large paydowns during the quarter, increased competition and the narrowing pricing spread in the current environment of increasing interest rates.

Interest income on commercial real estate loans, on a non-FTE basis, for the three months ended March 31, 2018 was $26.2 million, an increase of $3.3 million, or 14%, compared to the same period in 2017, as a result of a 5% increase in the average balance and a 35 basis point increase in the average yield on a non-FTE basis. The increase in the average balance for the three-month period is related to customer demand. The increase in the average yield for the three-month period is the result of market conditions as well as fluctuations in the indicies to which the variable rate loans are tied.

Interest income on construction and land loans for the three months ended March 31, 2018 was $1.9 million, an increase of $0.7 million, or 56%, compared to the same period in 2017, as a result of a 49% increase in the average balance and a 21 basis point increase in the average yield on a non-FTE basis. The increase in the average balance for the three-month period is related to customer demand. The increase in the average yield for the three-month period is the result of market conditions as well as fluctuations in the indicies to which the variable rate loans are tied.

Interest income on residential mortgage loans for the three months ended March 31, 2018 was $21.8 million, an increase of $2.8 million, or 15%, compared to the same period in 2017, as a result of an 11% increase in the average balance and a nine basis point increase in the average yield. The increase in the average balance for the three-month period is related to the organic growth of the residential loan portfolio at the Bank. The increase in the average yield for the three-month period is related to higher yields on residential mortgage originations and adjustable rate mortgage (“ARM”) loans repricing at higher rates.

Interest income on home equity loans for the three months ended March 31, 2018 was $1.0 million, a decrease of 4% compared to the same period in 2017, as a result of a 17% decrease in the average balance, partially offset by a 60 basis point increase in the average yield. The decrease in the average balance for the three-month period is primarily due to the timing of customer demand related to origination and utilization of loans. The increase in the average yield for the three-month period is the result of increases in the Prime rate.

Interest income on other consumer loans for the three months ended March 31, 2018 was $1.6 million, an increase of $0.2 million, or 11%, compared to the same period in 2017, as a result of a 44 basis point increase in the average yield, partially offset by a 3% decrease in the average balance. The increase in the average yield for the three-month period is primarily the result of increases in LIBOR. The decrease in the average balance for the three-month period is primarily due to customer demand related to origination and utilization of lines of credit.

Investment income, on a non-FTE basis, for the three months ended March 31, 2018 was $7.4 million, consistent with the same period in 2017, as a result of a 15 basis point increase in the average yield on a non-FTE basis, offset by a 9% decrease in the average balance. The increase in the average yield for the three-month period is primarily due to dividends from the Federal Reserve Bank, of which the Bank became a member in the third quarter of 2017, and the FHLB, as well as increases in the federal discount rate. The decrease in the average balance for the three-month period is primarily due to timing

and volume of deposit and borrowing balances as compared to the level of loans outstanding. Investment decisions are made based on anticipated liquidity, loan demand, and asset-liability management considerations.

Interest expense. Total interest expense for the three months ended March 31, 2018 was $11.0 million, an increase of $3.6 million, or 49%, compared to the same period in 2017.

Interest expense on interest-bearing deposits for the three months ended March 31, 2018 was $6.5 million, an increase of $2.0 million, or 44%, compared to the same period in 2017, as a result of an 18 basis point increase in the average rate paid, and a 1% increase in the average balance.

Interest paid on non-deposit interest-bearing liabilities for the three months ended March 31, 2018 was $4.4 million, an increase of $1.6 million, or 56%, compared to the same period in 2017, as a result of a 45 basis point increase in the average rate paid on FHLB borrowings and other borrowings, a 21% increase in the average balance of FHLB borrowings and other borrowings, and a 66 basis point increase in the average rate paid on junior subordinated debentures. The increase for the three-month period in the average rate paid on borrowings is due to the increases in benchmark interest rates.

Provision/ (credit) for loan losses. The Company recorded a credit to the provision for loan losses of $1.8 million for the three months ended March 31, 2018, compared to a credit to the provision for loan losses of $0.2 million for the same period in 2017. The credit to the provision for loan losses for the three months ended March 31, 2018 were the result of a decrease in criticized loans and improved loss factors, partially offset by loan growth and the mix in the loan portfolio.

The provision/ (credit) for loan losses is determined as a result of the required level of the allowance for loan losses, estimated by management, which reflects the inherent risk of loss in the loan portfolio as of the balance sheet dates. The Company incorporates both quantitative and qualitative loss factors to determine the appropriate level of the allowance for loan losses. Quantitative loss factors are based on historical net charge-offs by loan portfolio. Qualitative factors are estimated by management and include trends in problem loans, economic and business conditions, strength of management, real estate collateral values, and underwriting standards. For further details, see “Loan Portfolio and Credit Quality” below.

Total other income	308		186		122			66	%
Total fees and other income	$	39,743	$	36,506	$	3,237		9	%

Total fees and other income for the three months ended March 31, 2018increased$3.2 million, or 9%, compared to the same period in 2017. Factors affecting the increase in the three-month period include higher fee income in the Wealth Management and Trust, Investment Management, and Wealth Advisory segments due to higher levels of AUM.

• AUM managed or advised by the Investment Managers was $11.0 billion at March 31, 2018, an increase of $0.1 billion, compared to 2017. The increase in AUM was driven by positive market action of $0.8 billion, partially offset by negative net flows of $0.7 billion for the twelve months ending March 31, 2018. AUM managed by Anchor represents $9.0 billion of the balance at March 31, 2018 and $9.1 billion of the balance at March 31, 2017. Annualized investment management fees for the remaining 9 months of 2018 will be lower than the annualized investment management fees for the three months ended March 31, 2018 due to the completion of the sale of Anchor in April 2018. Anchor represented 74% of the investment management fee revenue for both of the three month periods ended March 31, 2018 and 2017.

51

• AUM managed or advised by the Wealth Advisors was $11.4 billion at March 31, 2018, an increase of $0.9 billion, or 8%, compared to March 31, 2017. The increase in AUM was driven by positive market action of $0.9 billion for the twelve months ending March 31, 2018. Net flows were flat for the twelve months ending March 31, 2018.

• AUM managed or advised by Boston Private Wealth was $7.8 billion at March 31, 2018, an increase of $0.6 billion, or 8%, compared to March 31, 2017. The increase is due to net inflows of $0.3 billion and positive market action of$0.2 billion for the twelve months ending March 31, 2018.

• Other banking fee income for the three months ended March 31, 2018increased compared to the same period in 2017. The increase was due to the increase in Bank Owned Life Insurance (“BOLI”) income, as the Company made an additional $50.0 million investment in BOLI in the first quarter of 2017, and as well as an increase in swap fee income reflecting higher client demand for loan swap agreements.

• Total other income for the three months ended March 31, 2018increased compared to the same period in 2017 related to fluctuations in gains and losses on fair market value adjustments on derivative agreements.

Total operating expense for the three months ended March 31, 2018increased$2.1 million, or 3%, compared to the same period in 2017 primarily due to increases in salaries and employee benefits, occupancy and equipment, and information systems, and other expense, partially offset by decreases in amortization of intangibles and professional services.

• Salaries and employee benefits expense, the largest component of operating expense, for the three months ended March 31, 2018increased compared to the same period in 2017 primarily due to higher performance-based compensation, salaries and benefits, partially offset by lower commissions, sales incentives, and stock compensation.

• Occupancy and equipment expense for the three months ended March 31, 2018increased compared to the same period in 2017 primarily due to an increase in rent expense and depreciation at new office locations.

• Marketing and business development expense for the three months ended March 31, 2018decreased compared to the same period in 2017 primarily related to the timing of marketing and advertising campaigns in the Private Banking and Wealth Advisory segments.

• Information systems expense for the three months ended March 31, 2018increased compared to the same period in 2017 primarily due to an increase in technology service agreements, telecom, and telephone expenses, partially offset by lower custody and recordkeeping expenses and software depreciation.

In 2017, the Bank began working on an initiative to upgrade its information technology. This initiative required the Bank to hire additional employees with expertise in information technology. Recruiters were generally used in the placement of these professionals. The Bank has utilized consultants and temporary employees to assist with the initiative in addition to the new hires. Generally the expenditures in the preliminary project stage were expensed as incurred. Other expenditures related to

52

the application development stage have been capitalized. The capitalized expenditures will be depreciated over the useful life of the asset when the asset is placed in service. The Bank anticipates that the capitalized assets will be placed in service in 2018 through early 2019.

Income Tax Expense. Income tax expense for continuing operations for the three months endedMarch 31, 2018 was $6.0 million. The effective tax rate for continuing operations for the three months ended March 31, 2018 was 21.5%, compared to an effective tax rate of 30.4% for the same period in 2017. The effective tax rate for 2018 was lower than 2017 primarily due to the impact of the Tax Cuts and Jobs Act (the “Tax Act”) that was enacted on December 22, 2017. Among the significant changes to the Code, the Tax Act reduced the federal corporate tax rate from 35% to 21% effective January 1, 2018. See Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 9: Income Taxes” for further detail.

Total Assets. Total assets remained flat at $8.3 billion at March 31, 2018 and December 31, 2017. Increases in total loans were offset by decreases in total cash and investments.

Cash and Investments. Total cash and investments (consisting of cash and cash equivalents, investment securities, and stock in the FHLB and the FRB) represent 16% of total assets at March 31, 2018 and 17% of total assets at December 31, 2017. The decrease was due to decreases in available-for-sale securities, held-to-maturity securities, stock in the FHLB and the FRB, and cash and cash equivalents. The changes in cash and investments were the net result of short-term fluctuations in liquidity due to changes in levels of deposits, borrowings and loans outstanding.

The majority of the investments held by the Company are held by the Bank. The Bank’s investment policy requires management to maintain a portfolio of securities which will provide liquidity necessary to facilitate funding of loans, to cover deposit fluctuations, and to mitigate the Bank’s overall balance sheet exposure to interest rate risk, while at the same time earning a satisfactory return on the funds invested. The securities in which the Bank may invest are subject to regulation and are generally limited to securities that are considered “investment grade.”

Investment maturities, redemptions, principal payments, and sales of securities, net of purchases, provided $35.5 million of cash proceeds during the three months ended March 31, 2018, compared to $3.7 million in the same period of 2017. Net proceeds are generally used to purchase new investments or fund a portion of loan growth. The timing of sales and reinvestments is based on various factors, including management’s evaluation of interest rate trends, credit risk, and the

53

Company’s liquidity. The Company’s available-for-sale investment portfolio carried a total of $2.1 million of unrealized gains and $32.2 million of unrealized losses at March 31, 2018, compared to $5.1 million of unrealized gains and $17.2 million of unrealized losses at December 31, 2017.

No impairment losses were recognized through earnings related to investment securities during the three months ended March 31, 2018 and 2017. The total amount of unrealized losses was primarily due to changes in interest rates since the securities were purchased.

Additionally, at March 31, 2018 and December 31, 2017, the Company held $70.8 million and $74.6 million, respectively, of held-to-maturity securities at amortized cost. All of the held-to-maturity securities were mortgage-backed securities guaranteed by U.S. government agencies or government-sponsored entities.

See Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 4: Investments” for further details of the Company’s investment securities.

Loans held for sale. Loans held for sale at March 31, 2018 decreased compared to the balance at December 31, 2017. The balance of loans held for sale usually relates to the timing and volume of residential loans originated for sale and the ultimate sale transaction which is typically executed within a short time following the loan origination. From time to time, the Company may also sell loans that have been held in the loan portfolio. The sale of such loans may improve the Bank’s liquidity and capital position or may provide the Bank additional flexibility for more profitable and strategic future lending opportunities.

Goodwill and intangible assets, net. Goodwill and intangible assets, net, decreased due to amortization of intangible assets. There was no change to goodwill during the three months ended March 31, 2018.

Goodwill and indefinite-lived intangible assets such as trade names are subject to annual impairment tests, or more frequently, if there is indication of impairment, based on guidance in ASC 350, Intangibles-Goodwill and Other. Long-lived intangible assets such as advisory contracts are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset or asset group may not be recoverable in accordance with ASC 360, Property, Plant, and Equipment (“ASC 360”).

Management performed its annual goodwill and indefinite-lived intangible asset impairment testing during the fourth quarter of 2017 for applicable reporting units. The estimated fair value of BOS, KLS, and Boston Private Wealth each exceeded their carrying value in 2017. The 2017 goodwill impairment testing resulted in a $24.9 million goodwill impairment charge at Anchor. The reduced carrying value of goodwill at Anchor of $42.1 million, along with the other assets and liabilities of Anchor, were classified as held for sale at March 31, 2018 and December 31, 2017 and are included within other assets and other liabilities, respectively, on the Company’s consolidated balance sheet. The sale transaction was completed in April 2018.

Total other assets. Total other assets, as presented in the table above, consists of the following line items from the consolidated balance sheet: premises and equipment, fees receivable, accrued interest receivable, deferred income taxes, net, and other assets including assets held for sale. Total other assets at March 31, 2018 increased compared to the balance at December 31, 2017. The increase was the result of increases in premises and equipment, other assets, and deferred income taxes, net.

• Premises and equipment increased $6.0 million, or 16%, to $43.6 million at March 31, 2018 from $37.6 million at December 31, 2017. In 2017, the Bank began working on an initiative to upgrade its information technology. The increase was primarily due to expenditures related to this initiative. Generally the expenditures in the preliminary project stage were expensed as incurred. Other expenditures related to the application development stage have been capitalized. The capitalized expenditures will be depreciated over the useful life of the asset when the asset is placed in service. The capitalized assets will be placed in service beginning in early 2018 through early 2019.

• Deferred income taxes, net, increased $3.0 million, or 10%, to $32.1 million at March 31, 2018 from $29.0 million at December 31, 2017. The increase was primarily due to the current year tax effect of other comprehensive income/ (loss), partially offset by deferred tax expense. At March 31, 2018, no valuation allowance on the net deferred tax asset was required due primarily to the expectation of future taxable income. Our use of these deferred tax benefits may depend on a number of factors including future changes in laws or regulations relating to tax rates, tax credits, tax deductions, and net operating losses.

• Other assets, which consist primarily of BOLI, assets held for sale, investment in partnerships, prepaid expenses, the fair value of interest rate derivatives, and other receivables, increased $4.8 million, or 2%, to $264.3 million at March 31, 2018 from $259.5 million at December 31, 2017. The increase was primarily due to additional cost

54

method investments, and increases in derivative assets and the value of BOLI policies, partially offset by a decrease in income taxes receivable.

Deposits. Deposits at March 31, 2018 increased compared to the balance at December 31, 2017. Deposits are the principal source of the Bank’s funds for use in lending, investments, and liquidity. Deposit levels can fluctuate from quarter to quarter as a result of large short-term transactions by commercial clients. Seasonality can also affect the deposit balances. The Bank typically experiences deposit outflows in the second quarter as a result of clients withdrawing funds for tax payments.

As a general matter, deposits are a cheaper source of funds than borrowings, because interest rates paid for deposits are typically less than interest rates charged for borrowings. If, as a result of general economic conditions, market interest rates, competitive pressures, or otherwise, the amount of deposits at the Bank decreases relative to its overall banking operations, the Bank may be limited in its ability to grow its loan portfolio or may have to rely more heavily on higher cost borrowings as a source of funds in the future.

The following table presents the composition of the Company’s deposits at March 31, 2018 and December 31, 2017:

	March 31, 2018				December 31, 2017
	Balance		as a % of total		Balance		as a % of total

_____________________

(1) Includes brokered deposits of $536.9 million and $780.2 million at March 31, 2018 and December 31, 2017, respectively.

Total borrowings. Total borrowings (consisting of securities sold under agreements to repurchase, federal funds purchased (if any), FHLB borrowings, and junior subordinated debentures) at March 31, 2018 decreased compared to the balance at December 31, 2017.

• FHLB borrowings decreased $82.1 million, or 12%, to $611.6 million at March 31, 2018 from $693.7 million at December 31, 2017. The decrease was primarily due to asset liability management considerations regarding the pricing of funds. FHLB borrowings are generally used to provide additional funding for loan growth when it is in excess of deposit growth and to manage interest rate risk, but can also be used as an additional source of liquidity for the Bank.

• From time to time, the Company purchases federal funds from the FHLB and other banking institutions to supplement its liquidity position. At March 31, 2018, the Company had no federal funds purchased outstanding. The Company had $30.0 million in federal funds purchased outstanding at December 31, 2017.

• Repurchase agreements increased $53.1 million to $85.3 million at March 31, 2018 from $32.2 million at December 31, 2017. Repurchase agreements are generally linked to commercial demand deposit accounts with an overnight sweep feature.

Total other liabilities. Total other liabilities, which consist primarily of accrued interest, liabilities held for sale, accrued bonus, interest rate derivatives, and other accrued expenses, at March 31, 2018 decreased compared to the balance at December 31, 2017. The decrease was primarily due to the payment in the first quarter of 2018 of accrued variable compensation, bonuses and employee benefits that had been accrued for at December 31, 2017, partially offset by increases in derivative liabilities.

55

Loan Portfolio and Credit Quality

Loans. Total portfolio loans increased $97.3 million, or 1%, to $6.6 billion, or 79% of total assets, at March 31, 2018, from $6.5 billion, or 78% of total assets, at December 31, 2017. Increases were recorded in residential loans of $54.8 million, or 2%; commercial real estate loans of $24.8 million, or 1%; consumer loans of $10.9 million, or 6%; commercial and industrial loans of $10.1 million, or 2%; commercial tax-exempt loans of $2.1 million, or less than one percent; and construction and land loans of $0.2 million, or less than one percent, partially offset by a decrease in home equity loans of $5.6 million, or 6%.

The ability to grow the loan portfolio is partially related to the Bank’s ability to increase deposit levels. Deposits are generally a cheaper source of funds than borrowings, because interest rates paid for deposits are typically less than interest rates charged for borrowings. If, as a result of general economic conditions, market interest rates, competitive pressures, or otherwise, the amount of deposits at the Bank decreases relative to its overall banking operations, the Bank may be limited in its ability to grow its loan portfolio or may have to rely more heavily on higher cost borrowings as a source of funds in the future. The Bank’s use of wholesale funding is limited as a result of internal policies such as the loans to deposits ratio.

The Bank specializes in lending to individuals, real estate investors, and middle market businesses, including corporations, partnerships, associations and nonprofit organizations. Loans made by the Bank to individuals may include residential mortgage loans and mortgage loans on investment or vacation properties, unsecured and secured personal lines of credit, home equity loans, and overdraft protection. Loans made by the Bank to businesses include commercial and mortgage loans, revolving lines of credit, working capital loans, equipment financing, community lending programs, and construction and land loans. The types and sizes of loans the Bank originates are limited by regulatory requirements. The Bank’s loans are affected by the economic and real estate markets in which they are located. Generally, commercial real estate, construction, and land loans are affected more than residential loans in an economic downturn.

The Bank’s commercial real estate loan portfolio, the largest portfolio segment after residential, includes loans secured by the following types of collateral at March 31, 2018: $713.9 million secured by multifamily and residential investment property; $641.3 million secured by retail property; $546.7 million secured by office and medical property; $206.2 million secured by manufacturing, industrial, and warehouse property; $161.3 million secured by hospitality property; and $195.6 million secured by other property. The Bank’s commercial real estate loan portfolio as of December 31, 2017 included loans secured by the following types of collateral:  $729.8 million secured by multifamily and residential investment property; $634.8 million secured by retail property; $543.9 million secured by office and medical property; $197.9 million secured by manufacturing, industrial, and warehouse property; $148.4 million secured by hospitality property; and $185.4 million secured by other property.

Allowance for loan losses. The allowance for loan losses is reported as a reduction of outstanding loan balances and totaled $72.9 million and $74.7 million as of March 31, 2018 and December 31, 2017, respectively.

The allowance for loan losses decreased $1.8 million to $72.9 million, or 1.10% of total loans, as of March 31, 2018 from $74.7 million, or 1.15% of total loans, as of December 31, 2017. The decrease in the overall allowance for loan losses was due to a decline in criticized loans and a decline in loss factors, partially offset by loan growth and the mix in the loan portfolio. See Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 7: Allowance for Loan Losses” for an analysis of the Company’s allowance for loan losses.

An analysis of the risk in the loan portfolio as well as management judgment is used to determine the estimated appropriate amount of the allowance for loan losses. The Company’s allowance for loan losses is comprised of three primary components (general reserves, allocated reserves on non-impaired special mention and substandard loans, and allocated reserves on impaired loans). See Part II. Item 8. “Notes to Unaudited Consolidated Financial Statements - Note 6: Allowance for Loan Losses” and the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 for further information.

The following table presents a summary of loans charged-off, net of recoveries, by geography for the periods indicated. The geography assigned to the data is based on the location of the regional offices to which the loans are attributed.

	Three months ended March 31,
	2018			2017
	(In thousands)
Net loans (charged-off)/ recovered:
New England	$	(285	)	$	79
San Francisco Bay Area	67			35
Southern California	169			21
Total net loans (charged-off)/ recovered	$	(49	)	$	135

There were less than $0.1 million in net charge-offs recorded in the first quarter of 2018, compared to $0.1 million of net recoveries for the same period of 2017.

The Company believes that commercial loans represent the greatest risk of loss due to the size and nature of these loans and the related collateral. Local economic and business conditions in the markets where our offices are located have a significant impact on our commercial loan customers and their ability to service their loans.

Nonperforming assets. The Company’s nonperforming assets include nonaccrual loans and OREO, if any. OREO, if any, consists of real estate acquired through foreclosure proceedings and real estate acquired through acceptance of deeds in lieu of foreclosure. As of March 31, 2018, nonperforming assets totaled $16.4 million, or 0.20% of total assets, an increase of $2.1 million, or 15%, compared to $14.3 million, or 0.17% of total assets, as of December 31, 2017.

The Bank’s policy is to discontinue the accrual of interest on a loan when the collectability of principal or interest in accordance with the contractual terms of the loan agreement is in doubt. Despite a loan having a current payment status, if the Bank has reason to believe it may not collect all principal and interest on the loan in accordance with the related contractual terms, the Bank will generally discontinue the accrual of interest income and will apply any future interest payments received to principal. Of the $16.4 million of loans on nonaccrual status as of March 31, 2018, $3.6 million, or 22%, had a current payment status, $3.4 million, or 20%, were 30-89 days past due, and $9.4 million, or 58%, were 90 days or more past due. Of the $14.3 million of loans on nonaccrual status as of December 31, 2017, $1.3 million, or 9%, had a current payment status, $3.4 million, or 24%, were 30-89 days past due, and $9.6 million, or 67%, were 90 days or more past due.

The Bank continues to evaluate the underlying collateral of each nonperforming loan and pursue the collection of interest and principal. Where appropriate, the Bank obtains updated appraisals on collateral. Reductions in fair values of the collateral for nonaccrual loans, if they are collateral dependent, could result in additional future provision for loan losses depending on the timing and severity of the decline. Reductions in fair values of the collateral for nonaccrual loans, if they are collateral dependent, could result in additional future provision for loan losses depending on the timing and severity of the decline. See Part I. Item 1. “Financial Statements and Supplementary Data - Note 6: Loans Portfolio and Credit Quality” for further information on nonperforming loans.

The Bank’s policy for returning a loan to accrual status requires the loan to be brought current and for the client to show a history of making timely payments (generally six consecutive months). For nonaccruing troubled debt restructured loans (“TDRs”), a return to accrual status generally requires timely payments for a period of six months in accordance with restructured terms, along with meeting other criteria.

Delinquencies. The past due status of a loan is determined in accordance with its contractual repayment terms. All loan types are reported past due when one scheduled payment is due and unpaid for 30 days or more. Loans 30-89 days past due decreased $4.6 million, or 18%, to $20.4 million as of March 31, 2018 from $25.0 million as of December 31, 2017. Loan delinquencies can be attributed to many factors, such as continuing weakness in, or deteriorating, economic conditions in the region in which the collateral is located, the loss of a tenant or lower lease rates for commercial borrowers, or the loss of income for consumers and the resulting liquidity impacts on the borrowers. Further deterioration in the credit condition of these delinquent loans could lead to the loans going to nonaccrual status and/or being downgraded. Downgrades would generally result in additional provision for loan losses. Past due loans may be included with accruing substandard loans.

In certain instances, although very infrequently, loans that have become 90 days or more past due may remain on accrual status if the value of the collateral securing the loan is sufficient to cover principal and interest and the loan is in the

58

process of collection. There were no loans 90 days or more past due, but still accruing, as of March 31, 2018 and December 31, 2017.

Impaired Loans. When management determines that it is probable that the Bank will not collect all principal and interest on a loan in accordance with the original loan terms, the loan is considered impaired. Certain impaired loans may continue to accrue interest based on factors such as the restructuring terms, if any, the historical payment performance, the value of collateral, and the financial condition of the borrower. Impaired commercial loans and impaired construction loans are typically, in accordance with ASC 310, individually evaluated for impairment. Large groups of smaller-balance homogeneous loans may be collectively evaluated for impairment. Such groups of loans may include, but are not limited to, residential loans, home equity loans, and consumer loans. However, if the terms of any of such loans are modified in a troubled debt restructuring, then such loans would be individually evaluated for impairment in the allowance for loan and lease losses.

Loans that are individually evaluated for impairment require an analysis to determine the amount of impairment, if any. For collateral dependent loans, impairment would be indicated as a result of the carrying value of the loan exceeding the estimated collateral value, less costs to sell, or, for loans not considered to be collateral dependent, the net present value of the projected cash flow, discounted at the loan’s contractual effective interest rate. Generally, when a collateral dependent loan becomes impaired, an updated appraisal of the collateral, if appropriate, is obtained. If the impaired loan has not been upgraded to a performing status within a reasonable amount of time, the Bank will continue to obtain updated appraisals, as deemed necessary, especially during periods of declining property values. Normally, shortfalls in the analysis of collateral dependent loans would result in the impairment amount being charged-off to the allowance for loan losses. Shortfalls on cash flow dependent loans may be carried as specific allocations to the general reserve unless a known loss is determined to have occurred, in which case such known loss is charged-off. Based on the impairment analysis, the provision could be higher or lower than the amount of provision associated with a loan prior to its classification as impaired. See Part II. Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 for detail on the Company’s treatment of impaired loans in the allowance for loan losses.

Impaired loans individually evaluated for impairment in the allowance for loan losses totaled $24.0 million as of March 31, 2018, a increase of $1.4 million, or 6%, compared to $22.6 million as of December 31, 2017. As of March 31, 2018, $6.4 million of the individually evaluated impaired loans had $0.3 million in specific reserve allocations. The remaining $17.6 million of individually evaluated impaired loans did not have specific reserve allocations due to the adequacy of collateral, prior charge-offs taken, interest collected and applied to principal, or a combination of these items. As of December 31, 2017, $8.1 million of individually evaluated impaired loans had $0.7 million in specific reserve allocations, and the remaining $14.5 million of individually evaluated impaired loans did not have specific reserve allocations.

The Bank may, under certain circumstances, restructure loans as a concession to borrowers who are experiencing financial difficulty. Such loans are classified as TDRs and are included in impaired loans. TDRs typically result from the Bank’s loss mitigation activities which, among other things, could include rate reductions, payment extensions, and/or principal forgiveness. As of March 31, 2018 and December 31, 2017, TDRs totaled $13.2 million and $13.6 million, respectively. As of March 31, 2018, $10.9 million of the $13.2 million in TDRs were on accrual status. As of December 31, 2017, $11.1 million of the $13.6 million in TDRs were on accrual status.

Potential Problem Loans. Loans that evidence weakness or potential weakness related to repayment history, the borrower’s financial condition, or other factors are reviewed by the Bank’s management to determine if the loan should be adversely classified. Delinquent loans may or may not be adversely classified depending upon management’s judgment with respect to each individual loan. The Bank classifies certain loans as “substandard,” “doubtful,” or “loss” based on criteria consistent with guidelines provided by banking regulators. Potential problem loans consist of accruing substandard loans where known information about possible credit problems of the related borrowers causes management to have doubts as to the ability of such borrowers to comply with the present loan repayment terms and which may result in classification of such loans as nonperforming at some time in the future. Management cannot predict the extent to which economic conditions may worsen or other factors which may impact borrowers and the potential problem loans. Triggering events for loan downgrades include updated appraisal information, inability of borrowers to cover debt service payments, loss of tenants or notification by the tenant of non-renewal of lease, inability of borrowers to sell completed construction projects, and the inability of borrowers to sell properties. Accordingly, there can be no assurance that other loans will not become 90 days or more past due, be placed on nonaccrual, be restructured, or require increased allowance coverage and provision for loan losses.

59

As of March 31, 2018, the Bank has identified $45.2 million in potential problem loans, a decrease of $8.2 million, or 15%, compared to $53.4 million as of December 31, 2017. Numerous factors impact the level of potential problem loans including economic conditions and real estate values. These factors affect the borrower’s liquidity and, in some cases, the borrower’s ability to comply with loan covenants such as debt service coverage. When there is a loss of a major tenant in a commercial real estate building, the appraised value of the building generally declines. Loans may be downgraded when this occurs as a result of the additional risk to the borrower in obtaining a new tenant in a timely manner and negotiating a lease with similar or better terms than the previous tenant. In many cases, these loans are still current and paying as agreed, although future performance may be impacted.

Liquidity

Liquidity is defined as the Company’s ability to generate adequate cash to meet its needs for day-to-day operations and material long and short-term commitments. Liquidity risk is the risk of potential loss if the Company were unable to meet its funding requirements at a reasonable cost. The Company manages its liquidity based on demand, commitments, specific events and uncertainties to meet current and future financial obligations of a short-term nature. The Company’s objective in managing liquidity is to respond to the needs of depositors and borrowers as well as earnings enhancement opportunities in a changing marketplace.

At March 31, 2018, the Company’s cash and cash equivalents amounted to $77.1 million. The Holding Company’s cash and cash equivalents amounted to $71.6 million at March 31, 2018. Management believes that the Holding Company and its affiliates, including the Bank, have adequate liquidity to meet their commitments for the foreseeable future.

Management is responsible for establishing and monitoring liquidity targets as well as strategies to meet these targets. At March 31, 2018 consolidated cash and cash equivalents and investment securities available-for-sale, less securities pledged against current borrowings and derivatives, amounted to $1.1 billion, or 13% of total assets, compared to $1.3 billion, or 15% of total assets at December 31, 2017. Future loan growth may depend upon the Company’s ability to continue to grow its core deposit levels. In addition, the Company has access to available borrowings through the FHLB totaling $1.2 billion at March 31, 2018, which decreased from December 31, 2017. Combined, this liquidity totals $2.3 billion, or 27% of assets and 35% of total deposits, as of March 31, 2018, compared to $2.5 billion, or 30% of assets and 38% of total deposits, at December 31, 2017.

The Bank has various internal policies and guidelines regarding liquidity, both on- and off-balance sheet, loans to assets ratio, and limits on the use of wholesale funds. These policies and/or guidelines require certain minimum or maximum balances or ratios be maintained at all times. In light of the provisions in the Bank’s internal liquidity policies and guidelines, the Bank will carefully manage the amount and timing of future loan growth along with its relevant liquidity policies and balance sheet guidelines. As a general matter, deposits are a cheaper source of funds than borrowings, because interest rates paid for deposits are typically less than interest rates charged for borrowings. If, as a result of general economic conditions, market interest rates, competitive pressures, or otherwise, the amount of deposits at the Bank decreases relative to its overall banking operations, the Bank may be limited in its ability to grow its loan portfolio or may have to rely more heavily on higher cost borrowings as a source of funds in the future.

Holding Company Liquidity. The Company and some of the Company’s majority-owned affiliates hold put and call options that would require the Company to purchase (and the noncontrolling interest owners of the majority-owned affiliates to sell) the remaining noncontrolling interests in these companies at either a contractually predetermined fair value, a multiple of EBITDA, or fair value, as determined by the respective agreements. At March 31, 2018, the estimated maximum redemption value for these affiliates related to outstanding put options was $16.3 million, all of which could be redeemed within the next 12 months, under certain circumstances, and is classified on the consolidated balance sheets as redeemable noncontrolling interests. The redeemable noncontrolling interest related to Anchor at March 31, 2018 of $6.5 million was eliminated upon the completion of the sale of Anchor in April 2018. These put and call options are discussed in detail in Part II. Item 8. “Financial Statements and Supplementary Data - Note 14: Noncontrolling Interests” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

62

The Holding Company’s primary sources of funds are dividends from its affiliates and access to the capital and debt markets. The Holding Company recognized $1.7 million in net income from discontinued operations during the three months ended March 31, 2018 as the final payment related to a revenue sharing agreement with Westfield Capital Management Company, LLC (“Westfield”). The Company will not receive additional net income from Westfield now that the final payment has been received. Although not a primary source of funds, the Holding Company has generated liquidity from the sale of affiliates in the past and also generated additional funds at the time of the Anchor sale closing in April 2018. Pursuant to the Anchor sale agreement, the Holding Company will be entitled to future revenue sharing payments that have a net present value of approximately $15 million in addition to the $32 million of cash received at the time of the sale closing in April 2018. The Company will also have a tax liability of $11 million to $12 million attributable to the transaction, which is primarily the result of a book to tax basis difference associated with nondeductible goodwill.

Dividends from the Bank are limited by various regulatory requirements relating to capital adequacy and retained earnings. See Part II. Item 5. “Market for Registrant’s Common Equity, Related Stockholders Matters, and Issuers Purchases of Equity Securities” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 for further details.

The Bank pays dividends to the Holding Company, subject to the approval of the Bank’s board of directors, depending on its profitability and asset growth. If regulatory agencies were to require banks to increase their capital ratios, or impose other restrictions, it may limit the ability of the Bank to pay dividends to the Holding Company and/or limit the amount that the Bank could grow.

Although the Bank’s capital currently exceeds regulatory requirements for capital, the Holding Company could downstream additional capital to increase the rate that the Bank could grow. Depending upon the amount of capital downstreamed by the Holding Company, the approval of the Holding Company’s board of directors may be required prior to the payment, if any.

The Company is required to pay interest quarterly on its junior subordinated debentures. The estimated cash outlay for the remaining nine months of 2018 for the interest payments is approximately $2.2 million based on the debt outstanding at March 31, 2018 and estimated LIBOR.

The Company presently plans to pay cash dividends on its common stock on a quarterly basis dependent upon a number of factors such as profitability, Holding Company liquidity, and the Company’s capital levels. However, the ultimate declaration of dividends by the board of directors of the Company will depend on consideration of, among other things, recent financial trends and internal forecasts, regulatory limitations, alternative uses of capital deployment, general economic conditions, and regulatory changes to capital requirements. Based on the current quarterly dividend rate of $0.12 per share, as announced by the Company on January 17, 2018, and estimated shares outstanding, the Company estimates that the amount to be paid out for dividends to common shareholders in the remaining nine months of 2018 will be approximately $30.5 million. The estimated dividend payments in 2018 could increase or decrease if the Company’s board of directors votes to increase or decrease, respectively, the current dividend rate, and/or the number of shares outstanding changes significantly.

Based on the shares of stock outstanding of 6.95% Non-Cumulative Perpetual Preferred Stock, Series D (“the Series D”), and the dividend rate, the Company would pay $2.6 million in cash dividends on preferred stock for the remaining nine months of 2018, if the same amount of shares remains outstanding for the remaining nine months of 2018. Although the dividend rate is set in the terms of the preferred stock, the quarterly preferred stock dividend payments are subject to approval by the Company’s board of directors. The Series D is callable by the Company beginning in June 2018. Should the Company call the Series D, the amount of cash outlay for dividend payments will be reduced.

In the first quarter of 2018, the Company’s board of directors approved, and the Company received regulatory non-objection for, a share repurchase program of up to $20.0 million of the Company’s outstanding common shares. Under the program, shares may be repurchased from time to time in the open market for a two-year period. As of March 31, 2018, the full $20.0 million remains available for repurchase. The amount and timing of repurchases will be based on the Company’s continuous evaluation of the program.

Bank Liquidity. The Bank has established various borrowing arrangements to provide additional sources of liquidity and funding. Management believes that the Bank currently has adequate liquidity available to respond to current demands. The Bank is a member of the FHLB of Boston, and as such, has access to short- and long-term borrowings from that institution. The FHLB can change the advance amounts that banks can utilize based on a bank’s current financial condition as obtained from publicly available data such as FDIC Call Reports. Decreases in the amount of FHLB borrowings available to the Bank would lower its liquidity and possibly limit the Bank’s ability to grow in the short-term. Management believes that the Bank has adequate liquidity to meet its commitments for the foreseeable future.

63

In addition to the above liquidity, the Bank has access to the FRB discount window facility, which can provide short-term liquidity as “lender of last resort,” brokered deposits, and federal funds lines. The use of non-core funding sources, including brokered deposits and borrowings, by the Bank may be limited by regulatory agencies. Generally, the regulatory agencies prefer that banks rely on core-funding sources for liquidity.

From time to time, the Bank purchases federal funds from the FHLB and other banking institutions to supplement its liquidity position. At March 31, 2018, the Bank had unused federal fund lines of credit totaling $465.0 million, compared to $435.0 million at December 31, 2017, with correspondent institutions to provide it with immediate access to overnight borrowings. At March 31, 2018, the Bank had no outstanding borrowings under the federal fund lines with these correspondent institutions and had $30.0 million of outstanding borrowings under the federal fund lines at December 31, 2017. Certain liquidity sources, such as federal funds lines, may be withdrawn by the correspondent bank at any time especially in the event of financial deterioration of the institution.

The Bank has also negotiated brokered deposit agreements with several institutions that have nationwide distribution capabilities. The Bank also participates in deposit placement services that can be used to provide customers to expanded deposit insurance coverage. At March 31, 2018, the Bank had $536.9 million of brokered deposits outstanding under these agreements, compared to $780.2 million at December 31, 2017.

If the Bank is no longer able to utilize the FHLB for borrowing, collateral currently used for FHLB borrowings could be transferred to other facilities such as the FRB’s discount window. In addition, the Bank could increase its usage of brokered deposits. Other borrowing arrangements may have higher rates than the FHLB would typically charge.

Capital Resources

Total shareholders’ equity at March 31, 2018 was $789.5 million, compared to $785.9 million at December 31, 2017, an increase of $3.6 million. The increase in shareholders’ equity was primarily the result of net income, partially offset by dividends paid and the change in accumulated other comprehensive income/ (loss).

The Company currently has one class of warrants to purchase common stock outstanding. These warrants were initially issued to the U.S. Department of the Treasury (the “TARP warrants”). As of March 31, 2018, 1,692,755 warrants were outstanding, before adjusting for dividends paid on the Company’s common stock in excess of $0.01 per share. The TARP warrants expire in November 2018.

The Company and the Bank are subject to capital rules issued by the Board of Governors of the Federal Reserve System (the “Federal Reserve”). Under these rules, the Company and the Bank are each required to maintain a minimum common equity Tier 1 capital to risk-weighted assets ratio of 4.5%, a minimum Tier 1 capital to risk-weighted assets ratio of 6.0%, a minimum total capital to risk-weighted assets ratio of 8% and a minimum Tier 1 leverage ratio of 4%. Additionally, subject to a transition schedule, these rules require the Company and the Bank to establish a capital conservation buffer of common equity Tier 1 capital in an amount above the minimum risk-based capital requirements for “adequately capitalized” institutions equal to 2.5% of total risk-weighted assets, or face restrictions on the ability to pay dividends, pay discretionary bonuses, and to engage in share repurchases.

A Federal Reserve-supervised institution, such as the Bank, is considered “well capitalized” if it (i) has a total capital to risk-weighted assets ratio of 10.0% or greater; (ii) a Tier 1 capital to risk-weighted assets ratio of 8.0% or greater; (iii) a common equity Tier 1 capital ratio to risk-weighted assets of 6.5% or greater, (iv) a Tier 1 leverage ratio of 5.0% or greater; and (iv) is not subject to any written agreement, order, capital directive, or prompt corrective action directive to meet and maintain a specific capital level for any capital measure. The Bank is currently considered “well capitalized” under all regulatory definitions.

The following table presents the Company’s and the Bank’s regulatory capital and related ratios as of March 31, 2018 and December 31, 2017. Also presented are the minimum requirements established by the Federal Reserve and the FDIC as of those dates for the Company and the Bank, respectively, to meet applicable capital requirements and the requirements of the FDIC as of those dates for the Bank to be considered “well capitalized” under all regulatory definitions. The Federal Reserve and the Massachusetts Division of Banks may impose higher capital ratios than those listed below based upon the results of regulatory exams.

As required by Rule 13a-15 under the Exchange Act, the Company has evaluated, with the participation of management, including the Chief Executive Officer and Chief Financial Officer, as of the end of the period covered by this report, the effectiveness of the design and operation of its disclosure controls and procedures. In designing and evaluating the Company’s disclosure controls and procedures, the Company and its management recognize that any controls and procedures, no matter how well designed and operated, can provide only a reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating and implementing possible controls and procedures.

Based on such evaluation, except for the exclusion noted in the preceding paragraph, the Chief Executive Officer and Chief Financial Officer have concluded that such disclosure controls and procedures were effective as of March 31, 2018 in ensuring that material information required to be disclosed by the Company, including its consolidated subsidiaries, was made known to the certifying officers by others within the Company and its consolidated subsidiaries in the reports that it files or submits under the Exchange Act and is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms. On a quarterly basis, the Company evaluates the disclosure controls and procedures, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that the Company’s systems evolve with its business.

(b) Change in internal controls over financial reporting.

There have been no changes in the Company’s internal controls over financial reporting that occurred during the quarter ended March 31, 2018, that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting.

Basis of Presentation and Summary of Significant Accounting Policies

Boston Private Financial Holdings, Inc. (the “Company” or “BPFH”), is a bank holding company (the “Holding Company”) with four reportable segments: Private Banking, Wealth Management and Trust, Investment Management, and Wealth Advisory.

The Private Banking segment is comprised of the banking operations of Boston Private Bank & Trust Company (the “Bank” or “Boston Private Bank”), a trust company chartered by The Commonwealth of Massachusetts, insured by the Federal Deposit Insurance Corporation (the “FDIC”), and a wholly-owned subsidiary of the Company. Boston Private Bank is a member of the Federal Reserve Bank of Boston. Boston Private Bank primarily operates in three geographic markets: New England, the San Francisco Bay Area, and Southern California.

The Wealth Management and Trust segment is comprised of the operations of Boston Private Wealth LLC (“Boston Private Wealth”), a wholly-owned subsidiary of Boston Private Bank, and the trust operations of Boston Private Bank. The segment offers investment management, wealth management, family office, and trust services to individuals, families, and institutions. The Wealth Management and Trust segment operates in New England; South Florida; California; and Madison, Wisconsin.

The Investment Management segment had two consolidated affiliates, Dalton, Greiner, Hartman, Maher & Co., LLC (“DGHM”) and Anchor Capital Advisors, LLC (“Anchor”) (together, the “Investment Managers”) included in its results for the first quarter of 2018, while the assets and liabilities of Anchor were classified as held for sale. Assets held for sale were$60.2 million and $58.8 million at March 31, 2018 and December 31, 2017, respectively, and liabilities held for sale were $4.7 million and $3.2 million at March 31, 2018 and December 31, 2017, respectively. In December 2017, the Company entered into an agreement to sell its entire ownership interest in Anchor in a transaction that would result in Anchor being majority-owned by members of its management team. The transaction closed in April 2018.

The Wealth Advisory segment has two consolidated affiliates, consisting of KLS Professional Advisors Group, LLC (“KLS”) and Bingham, Osborn & Scarborough, LLC (“BOS”) (together, the “Wealth Advisors” and, together with the Wealth Management and Trust and Investment Management segments, the “Wealth and Investment businesses”).

The Company conducts substantially all of its business through its four reportable segments. All significant intercompany accounts and transactions have been eliminated in consolidation.

The unaudited interim consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), and include all necessary adjustments of a normal recurring nature which, in the opinion of management, are required for a fair presentation of the results of operations and financial condition of the Company. The interim results of consolidated operations are not necessarily indicative of the results for the entire year.

The information in this report should be read in conjunction with the consolidated financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the Securities and Exchange Commission (“SEC”). Prior period amounts are reclassified whenever necessary to conform to the current period presentation.

The Company’s significant accounting policies are described in Part II. Item 8. “Financial Statements and Supplementary Data - Note 1: Basis of Presentation and Summary of Significant Accounting Policies” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the SEC. For interim reporting purposes, the Company follows the same significant accounting policies, except for the following new accounting pronouncements from the Financial Accounting Standards Board (the “FASB”) that were adopted effective January 1, 2018:

• Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”). As a result of implementing this standard, the Company reclassified $5 thousand in unrealized losses on derivatives related to hedge ineffectiveness from accumulated other comprehensive income to retained earnings as of January 1, 2018. This ASU will provide more flexibility in the Company’s risk management activities and we believe it will enhance the Company’s ability to employ risk management strategies, while improving the transparency and understanding of those strategies for financial statement users.

• ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (“ASU 2017-07”). This amendment requires an employer to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. As a result of the retrospective adoption of this ASU, $160 thousand for the three months ended March 31, 2017 has been reclassified from salaries and employee benefits expense to other expense within the Company’s consolidated statement of operations. For the three months ended March 31, 2018, $135 thousand is presented within other expense that would have been presented within salaries and employee benefits prior to adoption of ASU 2017-07.

• ASU 2016-15, Statement of Cash Flows (Topic 230) (“ASU 2016-15”).  This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. This ASU is effective for the Company beginning on January 1, 2018. The guidance requires application using a retrospective transition method. This ASU did not have an impact on the Company’s consolidated financial statements.

• ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). This amendment requires equity investments to be measured at fair value with changes in fair value, net of tax, recognized in net income. As a result of implementing this standard, the Company reclassified $339 thousand in unrealized gains on available-for-sale equity investments, net of tax, from accumulated other comprehensive income to retained earnings as of January 1, 2018.

• ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which was subsequently amended by additional ASUs, including ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) and ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, collectively, “ASU 2014-09 et al.” ASU 2014-09 et al. was adopted using the modified retrospective transition method as of January 1, 2018, however no cumulative effect adjustment was required. This new guidance was applied to all revenue contracts in place at the date of adoption. See Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 13: Revenue Recognition” for further details.

(1) See Part II. Item 8. “Financial Statements and Supplementary Data - Note 14: Noncontrolling Interests” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 for a description of the redemption values related to the redeemable noncontrolling interests. In accordance with the FASB Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”), an increase in redemption value from period to period reduces income attributable to common shareholders. Decreases in redemption value from period to period increase income attributable to common shareholders, but only to the extent that the cumulative change in redemption value remains a cumulative increase since adoption of this standard in the first quarter of 2009.

(2) The diluted EPS computations for the three months ended March 31, 2018 and 2017 do not assume the conversion, exercise, or contingent issuance of the following shares for the following periods because the result would have been anti-dilutive for the periods indicated. As a result of the anti-dilution, the potential common shares excluded from the diluted EPS computation are as follows:

(1)  All mortgage-backed securities are guaranteed by U.S. government agencies or government-sponsored entities.

As of March 31, 2018, the U.S. government and agencies securities, government-sponsored entities securities and mortgage-backed securities in the first table above had current Standard and Poor’s credit ratings of AAA. The municipal bonds in the first table above had a current Standard and Poor’s credit rating of at least AA-. At March 31, 2018, the Company does not consider these investments other-than-temporarily impaired because the decline in fair value on investments is primarily attributed to changes in interest rates and not credit quality.

At March 31, 2018 and December 31, 2017, the amount of investment securities in an unrealized loss position greater than 12 months, as well as in total, was primarily due to changes in interest rates. As of March 31, 2018, the Company had no intent to sell any securities in an unrealized loss position and it is not more likely than not that the Company would be forced to sell any of these securities prior to the full recovery of all unrealized loss amounts.

Cost method investments, which are included in other assets, can be temporarily impaired when the fair values decline below the amortized costs of the individual investments. There were no cost method investments with unrealized losses as of March 31, 2018 or December 31, 2017. The Company’s cost method investments primarily include low income housing partnerships which generate tax credits. The Company also holds partnership interests in venture capital funds formed to provide financing to small businesses and to promote community development. The Company had $41.8 million and $39.4 million in cost method investments included in other assets as of March 31, 2018 and December 31, 2017, respectively.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

Fair Value Measurements

Fair value is defined under GAAP as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants on the measurement date. The Company determines the fair values of its financial instruments based on the fair value hierarchy established in ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 describes three levels of inputs that may be used to measure fair value. Financial instruments are considered Level 1 when valuation can be based on quoted prices in active markets for identical assets or liabilities. Level 2 financial instruments are valued using quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or models using inputs that are observable or can be corroborated by observable market data of substantially the full term of the assets or liabilities. Financial instruments are considered Level 3 when their values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable and when determination of the fair value requires significant management judgment or estimation.

The following tables present the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2018 and December 31, 2017, aggregated by the level in the fair value hierarchy within which those measurements fall:

As of March 31, 2018 and December 31, 2017, available-for-sale securities consisted of U.S. government and agency securities, government-sponsored entities securities, municipal bonds, mortgage-backed securities, and other available-for-sale securities. Available-for-sale Level 1 securities are valued with prices quoted in active markets and include U.S. Treasury securities (which are categorized as U.S. government and agencies securities) and equities (which are categorized as other available-for-sale securities). Available-for-sale Level 2 securities generally have quoted prices but are traded less frequently than exchange-traded securities and can be priced using market data from similar assets and include government-sponsored entities securities, municipal bonds, mortgage-backed securities, and certain investments in SBA loans (which are categorized as U.S. government and agencies securities). No investments held as of March 31, 2018 or December 31, 2017 were categorized as Level 3. There were no changes in the valuation techniques used for measuring the fair value of available-for-sale securities in the three months ended March 31, 2018.

In managing its interest rate and credit risk, the Company utilizes derivative instruments including interest rate customer swaps, interest rate swaps, and risk participation agreements. As a service to its customers, the Company may utilize derivative instruments including customer foreign exchange forward contracts to manage its foreign exchange risk, if any. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities, and therefore, they have been categorized as a Level 2 measurement as of March 31, 2018 and December 31, 2017. See Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 8: Derivatives and Hedging Activities” for further details.

To comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Counterparty exposure is evaluated by netting positions that are subject to master netting agreements, as well as considering the amount of collateral securing the position.

The Company has determined that the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, although the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy as of March 31, 2018 and December 31, 2017.

Other investments, which are not considered available-for-sale investments, consist of publicly traded mutual fund investments held in deferred compensation trusts that are valued at prices quoted in active markets. Therefore, they have been categorized as a Level 1 measurement as of March 31, 2018 and December 31, 2017.

There were no transfers between levels for assets or liabilities recorded at fair value on a recurring basis during the three months endedMarch 31, 2018 and 2017.

There were no Level 3 assets valued on a recurring basis at March 31, 2018 or December 31, 2017.

The following table presents the Company’s assets and liabilities measured at fair value on a non-recurring basis during the period ended March 31, 2018, aggregated by the level in the fair value hierarchy within which those measurements fall. There were no collateral-dependent impaired loans held at March 31, 2017 that had write-downs in fair value or whose specific reserve changed during the first three months of 2017.

(1) Collateral-dependent impaired loans held at March 31, 2018 that had write-downs in fair value or whose specific reserve changed during the first three months of 2018.

The following table presents additional quantitative information about assets measured at fair value on a non-recurring basis for which the Company has utilized Level 3 inputs to determine fair value:

	As of March 31, 2018
	Fair Value		Valuation Technique	Unobservable Input	Range of Inputs Utilized	Weighted Average of Inputs Utilized
	(In thousands)
Impaired Loans	$	1,835	Appraisals of Collateral	Discount for costs to sell	0% - 24%	14%
				Appraisal adjustments	0% - 26%	16%

Impaired loans include those loans that were adjusted to the fair value of underlying collateral as required under ASC 310, Receivables. The amount does not include impaired loans that are measured based on expected future cash flows discounted at the respective loan’s original effective interest rate, as that amount is not considered a fair value measurement. The Company uses appraisals, which management may adjust to reflect estimated fair value declines, or apply other discounts to appraised values for unobservable factors resulting from its knowledge of the property or consideration of broker quotes. The appraisers use a market, income, and/or a cost approach in determining the value of the collateral. Therefore they have been categorized as a Level 3 measurement.

The following tables present the carrying values and fair values of the Company’s financial instruments that are not measured at fair value on a recurring basis:

The estimated fair values have been determined by using available quoted market information or other appropriate valuation methodologies. The aggregate fair value amounts presented above do not represent the underlying value of the financial assets and liabilities of the Company taken as a whole as they do not reflect any premium or discount the Company might recognize if the assets were sold or the liabilities sold, settled, or redeemed. An excess of fair value over book value on financial assets represents a premium, or gain, the Company might recognize if the assets were sold, while an excess of book value over fair value on financial liabilities represents a premium, or gain, the Company might recognize if the liabilities were sold, settled, or redeemed prior to maturity. Conversely, losses would be recognized if assets were sold where the book value exceeded the fair value or liabilities were sold where the fair value exceeded the book value.

The fair value estimates provided are made at a specific point in time, based on relevant market information and the characteristics of the financial instrument. The estimates do not provide for any premiums or discounts that could result from concentrations of ownership of a financial instrument. Because no active market exists for some of the Company’s financial instruments, certain fair value estimates are based on subjective judgments regarding current economic conditions, risk characteristics of the financial instruments, future expected loss experience, prepayment assumptions, and other factors. The resulting estimates involve uncertainties and are considered best estimates. Changes made to any of the underlying assumptions could significantly affect the estimates.

Cash and cash equivalents

The carrying value reported in the balance sheet for cash and cash equivalents approximates fair value due to the short-term nature of their maturities and are classified as Level 1.

Held-to-maturity investment securities

Held-to-maturity securities currently include mortgage-backed securities. The mortgage-backed securities are fixed income instruments that are not quoted on an exchange, but may be traded in active markets. The fair value of these securities is based on quoted market prices obtained from external pricing services. The principal market for our securities portfolio is the secondary institutional market, with an exit price that is predominantly reflective of bid level pricing in that market.Accordingly, held-to-maturity mortgage-backed securities are included in the Level 2 fair value category.

Loans held for sale

Loans held for sale are recorded at the lower of cost or fair value in the aggregate. Fair value estimates are based on actual commitments to sell the loans to investors at an agreed upon price or current market prices if rates have changed since the time the loan closed. Accordingly, loans held for sale are included in the Level 2 fair value category.

Loans, net

Fair value estimates are based on loans with similar financial characteristics. Fair values of commercial and residential mortgage loans are estimated by discounting contractual cash flows adjusted for prepayment estimates and using discount rates approximately equal to current market rates on loans with similar credit and interest rate characteristics and maturities. The fair value estimates for home equity and other loans are based on outstanding loan terms and pricing in the local markets. Net loans are included in the Level 3 fair value category based upon the inputs and valuation techniques used.

Other financial assets

Other financial assets consist of accrued interest and fees receivable, and stock in the Federal Home Loan Bank of Boston (“FHLB”) and the Federal Reserve Bank (“FRB”), for which the carrying amount approximates fair value, and are classified as Level 2.

Deposits

The fair values reported for transaction accounts (demand, NOW, savings, and money market) equal their respective book values reported on the balance sheet and are classified as Level 2. The fair values disclosed are, by definition, equal to the amount payable on demand at the reporting date. The fair values for certificates of deposit are based on the discounted value of contractual cash flows. The discount rates used are representative of approximate rates currently offered on certificates of deposit with similar remaining maturities and are classified as Level 2.

Securities sold under agreements to repurchase

The fair value of securities sold under agreements to repurchase is estimated based on contractual cash flows discounted at the Bank’s incremental borrowing rate for FHLB borrowings with similar maturities and have been classified as Level 2.

Federal funds purchased

The carrying amounts of federal funds purchased approximate fair value due to their short-term nature and therefore these funds have been classified as Level 2.

Federal Home Loan Bank borrowings

The fair value reported for FHLB borrowings is estimated based on the discounted value of contractual cash flows. The discount rate used is based on the Bank’s estimated current incremental borrowing rate for FHLB borrowings of similar maturities and therefore these borrowings have been classified as Level 2.

Junior subordinated debentures

The fair value of the junior subordinated debentures issued by Boston Private Capital Trust I and Boston Private Capital Trust II were estimated using Level 3 inputs such as the interest rates on these securities, current rates for similar debt, a consideration for illiquidity of trading in the debt, and regulatory changes that would result in an unfavorable change in the regulatory capital treatment of this type of debt.

Other financial liabilities

Other financial liabilities consists of accrued interest payable for which the carrying amount approximates fair value and is classified as Level 2.

Financial instruments with off-balance sheet risk

The Bank’s commitments to originate loans and for unused lines and outstanding letters of credit are primarily at market interest rates and therefore, the carrying amount approximates fair value.

Loan Portfolio and Credit Quality

The Bank’s lending activities are conducted principally in the regions of New England, the San Francisco Bay Area, and Southern California. The Bank originates single and multi-family residential loans, commercial real estate loans, commercial and industrial loans, commercial tax-exempt loans, construction and land loans, and home equity and other consumer loans. Most loans are secured by borrowers’ personal or business assets. The ability of the Bank’s single family residential and consumer borrowers to honor their repayment commitments is generally dependent on the level of overall economic conditions within the Bank’s lending areas. Commercial, construction, and land borrowers’ ability to repay is generally dependent upon the health of the economy and real estate values, including, in particular, the performance of the construction sector. Accordingly, the ultimate collectability of a substantial portion of the Bank’s loan portfolio is susceptible to changing conditions in the New England, the San Francisco Bay Area, and Southern California economies and real estate markets.

The following table presents a summary of the loan portfolio based on the portfolio segment as of the dates indicated:

The Bank’s policy is to discontinue the accrual of interest on a loan when the collectability of principal or interest is in doubt. In certain instances, although infrequent, loans that have become 90 days or more past due may remain on accrual status if the value of the collateral securing the loan is sufficient to cover principal and interest and the loan is in the process of collection. There were no loans 90 days or more past due, but still accruing as of both March 31, 2018 and December 31, 2017. The Bank’s policy for returning a loan to accrual status requires the loan to be brought current and for the client to show a history of making timely payments (generally six consecutive months). For troubled debt restructured loans (“TDRs”), a return to accrual status generally requires timely payments for a period of six months in accordance with the restructured loan terms, along with meeting other criteria.

The following tables show the payment status of loans receivable by class of receivable as of the dates indicated:

Nonaccrual and delinquent loans are affected by many factors, such as economic and business conditions, interest rates, unemployment levels, and real estate collateral values, among others. In periods of prolonged economic decline, borrowers may become more severely affected over time as liquidity levels decline and the borrower’s ability to continue to make payments deteriorates. With respect to real estate collateral values, the declines from the peak, as well as the value of the real estate at the time of origination versus the current value, can impact the level of problem loans. For instance, if the loan to value ratio at the time of renewal has increased due to the decline in the real estate value since origination, the loan may no longer meet the Bank’s underwriting standards and may be considered for classification as a problem loan dependent upon a review of risk factors.

Generally when a collateral dependent loan becomes impaired, an updated appraisal of the collateral, if appropriate, is obtained. If the impaired loan has not been upgraded to a performing status within a reasonable amount of time, the Bank will continue to obtain updated appraisals as deemed necessary, especially during periods of declining property values.

The past due status of a loan is determined in accordance with its contractual repayment terms. All loan types are reported past due when one scheduled payment is due and unpaid for 30 days or more.

Credit Quality Indicators

The Bank uses a risk rating system to monitor the credit quality of its loan portfolio. Loan classifications are assessments made by the Bank of the status of the loans based on the facts and circumstances known to the Bank, including management’s judgment, at the time of assessment. Some or all of these classifications may change in the future if there are unexpected changes in the financial condition of the borrower, including but not limited to, changes resulting from continuing deterioration in general economic conditions on a national basis or in the local markets in which the Bank operates adversely affecting, among other things, real estate values. Such conditions, as well as other factors which adversely affect borrowers’ ability to service or repay loans, typically result in changes in loan default and charge-off rates, and increased provisions for loan losses, which would adversely affect the Company’s financial performance and financial condition. These circumstances are not entirely foreseeable and, as a result, it may not be possible to accurately reflect them in the Company’s analysis of credit risk. Generally, only commercial loans, including commercial real estate, other commercial and industrial loans, commercial tax-exempt loans, and construction and land loans, are given a numerical grade.

A summary of the rating system used by the Bank, repeated here from Part II. Item 8. “Financial Statements and Supplementary Data - Note 1: Basis of Presentation and Summary of Significant Accounting Policies,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, follows:

Pass - All loans graded as pass are considered acceptable credit quality by the Bank and are grouped for purposes of calculating the allowance for loan losses. For residential, home equity and consumer loans, the Bank classifies loans as pass unless there is known information such as delinquency or client requests for modifications which, due to financial difficulty, would then generally result in a risk rating such as special mention or more severe depending on the factors.

Special Mention - Loans rated in this category are defined as having potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may, at some future date, result in the deterioration of the repayment prospects for the credit or the Bank’s credit position. These loans are currently protected but have the potential to deteriorate to a substandard rating. For commercial loans, the borrower’s financial performance may be inconsistent or below forecast, creating the possibility of liquidity problems and shrinking debt service coverage. In loans having this rating, the primary source of repayment is still good, but there is increasing reliance on collateral or guarantor support. Collectability of the loan is not yet in jeopardy. In particular, loans in this category are considered more variable than other categories, since they will typically migrate through categories more quickly.

Substandard - Loans rated in this category are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. A substandard credit has a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Substandard loans may be either still accruing or nonaccruing depending upon the severity of the risk and other factors such as the value of the collateral, if any, and past due status.

Doubtful - Loans rated in this category indicate that collection or liquidation in full on the basis of currently existing facts, conditions, and values, is highly questionable and improbable. Loans in this category are usually on nonaccrual and classified as impaired.

(1) Recorded investment represents the client loan balance net of historical charge-offs and historical nonaccrual interest paid, which was applied to principal.

When management determines that it is probable that the Bank will not collect all principal and interest on a loan in accordance with the original loan terms, the loan is designated as impaired.

Loans that are designated as impaired require an analysis to determine the amount of impairment, if any. Impairment would be indicated as a result of the carrying value of the loan exceeding the estimated collateral value, less costs to sell, for collateral dependent loans or the net present value of the projected cash flow, discounted at the loan’s contractual effective interest rate, for loans not considered to be collateral dependent. Generally, shortfalls in the analysis on collateral dependent loans would result in the impairment amount being charged-off to the allowance for loan losses. Shortfalls on cash flow dependent loans may be carried as specific allocations to the general reserve unless a known loss is determined to have occurred, in which case such known loss is charged-off.

Loans in the held for sale category are carried at the lower of amortized cost or estimated fair value in the aggregate and are excluded from the allowance for loan losses analysis.

The Bank may, under certain circumstances, restructure loans as a concession to borrowers who are experiencing financial difficulty. Such loans are classified as TDRs and are included in impaired loans. TDRs typically result from the Bank’s loss mitigation activities which, among other things, could include rate reductions, payment extensions, and/or principal forgiveness. As of March 31, 2018 and December 31, 2017, TDRs totaled $13.2 million and $13.6 million, respectively. As of March 31, 2018, $10.9 million of the $13.2 million in TDRs were on accrual status. As of December 31, 2017, $11.1 million of the $13.6 million in TDRs were on accrual status.

Since all TDR loans are considered impaired loans, they are individually evaluated for impairment. The resulting impairment, if any, would have an impact on the allowance for loan losses as a specific reserve or charge-off. If, prior to the classification as a TDR, the loan was not impaired, there would have been a general or allocated reserve on the particular loan. Therefore, depending upon the result of the impairment analysis, there could be an increase or decrease in the related allowance for loan losses. Many loans initially categorized as TDRs are already on nonaccrual status and are already considered impaired. Therefore, there is generally not a material change to the allowance for loan losses when a nonaccruing loan is categorized as a TDR. There were no loans that were restructured or defaulted during the three months ended March 31, 2018 or 2017.

Loan participations serviced for others and loans serviced for others are not included in the Company’s total loans. The following table presents a summary of the loan participations serviced for others and loans serviced for others based on class of receivable as of the dates indicated:

The allowance for loan losses is an estimate of the inherent risk of loss in the loan portfolio as of the consolidated balance sheet dates. Management estimates the level of the allowance based on all relevant information available. Changes to the required level in the allowance result in either a provision for loan loss expense, if an increase is required, or a credit to the provision, if a decrease is required. Loan losses are charged to the allowance when available information confirms that specific loans, or portions thereof, are uncollectible. Recoveries on loans previously charged-off are credited to the allowance when received in cash.

The provision/ (credit) for loan losses and related balance in the allowance for loan losses for tax-exempt commercial and industrial loans are included with commercial and industrial. The provision/ (credit) for loan losses and related balance in the allowance for loan losses for tax-exempt commercial real estate loans are included with commercial real estate. There were no charge-offs or recoveries, for any period presented, for both commercial and industrial and commercial real estate tax-exempt loans.

The following tables present the Company’s allowance for loan losses and loan portfolio at March 31, 2018 and December 31, 2017 by portfolio segment, disaggregated by method of impairment analysis. The Company had no loans acquired with deteriorated credit quality at March 31, 2018 or December 31, 2017.

Derivatives and Hedging Activities

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and, to a lesser extent, the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are generally determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to certain loans, deposits, and borrowings. As a service to its customers, the Company may utilize

derivative instruments including customer foreign exchange forward contracts to manage its foreign exchange risk, if any.

The following table presents the fair value of the Company’s derivative financial instruments as well as their classification on the consolidated balance sheets as of March 31, 2018 and December 31, 2017:

(1) There was an additional $(4) thousand loss related to the ineffective portion for the three months ended as of March 31, 2017. The guidance in ASU 2017-12 requires that amounts in accumulated other comprehensive income that are included in the assessment of effectiveness should be reclassified into earnings in the same period in which the hedged forecasted transactions impact earnings. Transition guidance for this ASU further states that upon adoption, previously recorded cumulative ineffectiveness for cash flow hedges existing at the adoption date be eliminated by means of a cumulative-effect adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the initial application date. There was a $5 thousand reclassification related to the adoption of ASU 2017-12 effective January 1, 2018.

The Bank has agreements with its derivative counterparties that contain provisions where, if the Bank defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Bank could also be declared in default on its derivative obligations. The Bank was in compliance with these provisions as of March 31, 2018 and December 31, 2017.

The Bank also has agreements with certain of its derivative counterparties that contain provisions where, if the Bank fails to maintain its status as a well- or adequately-capitalized institution, then the counterparty could terminate the derivative positions and the Bank would be required to settle its obligations under the agreements. The Bank was in compliance with these provisions as of March 31, 2018 and December 31, 2017.

Certain of the Bank’s agreements with its derivative counterparties contain provisions where, if specified, events or conditions occur that materially change the Bank’s creditworthiness in an adverse manner, the Bank may be required to fully collateralize its obligations under the derivative instruments. The Bank was in compliance with these provisions as of March 31, 2018 and December 31, 2017.

As of March 31, 2018 there were no termination amounts related to collateral determinations of derivatives in a liability position and as of December 31, 2017, the termination amount was $3.1 million. The Company has minimum collateral posting thresholds with its derivative counterparties and pledged securities with market values of $2.2 million and $2.3 million, respectively, as of March 31, 2018 and December 31, 2017, against its obligations under these agreements. The collateral posted is typically greater than the current liability position; however, due to timing of liability position changes at period end, the funding of a collateral shortfall may take place shortly following period end.

Cash Flow Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company has entered into interest rate swaps as part of its interest rate risk management strategy.  These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed payments.  The Company has entered into interest rate swaps to hedge London Interbank Offered Rate (“LIBOR”) -indexed brokered deposits and the LIBOR component of the total cost of certain FHLB borrowings.

To accomplish this objective and strategy, the Bank has entered into a total of six interest rate swaps, two during 2017 with effective dates of March 22, 2017 and four during 2013 with effective dates of September 2, 2014, June 1, 2014, March 1, 2014, and August 1, 2013.

The two interest rate swaps entered into during 2017 have notional amounts of $40 million and $60 million with terms of 1.75 and 2.25 years, respectively. These interest rate swaps will effectively fix the Bank’s interest payments on $100 million in interest-related cash outflows attributable to changes in the LIBOR component of FHLB borrowing liabilities at rates of 1.55% and 1.65%, respectively, with a weighted average rate of 1.61%. The borrowings hedged will initially be expected to be issuances and quarterly rollovers of three-month FHLB advances but may also then include future issuances of three-month repurchase agreements with similar characteristics and/or future issuances of either floating or fixed rate borrowings that are issued with the specific intent to replace the quarterly rollovers of the advances or repurchase agreements.

The four interest rate swaps entered into during 2013 each have a notional amount of $25 million and have terms ranging from four to six years from their respective effective dates. The interest rate swaps effectively fix the Bank’s interest payments on $125 million of its LIBOR-indexed deposit liabilities at rates between 1.68% and 2.32%, with a weighted average rate of 1.95%.

Prior to the implementation of ASU 2017-12, which was implemented on a modified retrospective basis on January 1, 2018, the Company used the “Hypothetical Derivative Method” described in ASC 815, Derivatives and Hedging (“ASC 815”), for quarterly prospective and retrospective assessments of hedge effectiveness, as well as for measurements of hedge ineffectiveness. Under this method, the Company assessed the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged transactions. The effective portion of changes in the fair value of the derivative was initially reported in other comprehensive income (“OCI”) (outside of earnings) and subsequently reclassified to earnings in interest and dividend income when the hedged transactions affect earnings. Ineffectiveness resulting from the hedge was recorded as a gain or loss in the consolidated statement of operations as part of fees and other income.

Upon implementation of ASU 2017-12, for derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income and subsequently reclassified into interest expense in the same period during which the hedged transaction affects earnings. A portion of the balance reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made or received on the Company’s interest rate swaps. During the next twelve months, the Company estimates that $1.1 million will be reclassified as a decrease in interest expense. The Company monitors the risk of counterparty default on an ongoing basis.

Non-designated Hedges

Derivatives not designated as hedges are not speculative and result from different services the Bank provides to qualified commercial clients. The Bank offers certain derivative products directly to such clients. The Bank economically hedges derivative transactions executed with commercial clients by entering into mirror-image, offsetting derivatives with third parties. Derivative transactions executed as part of these programs are not designated in ASC 815-qualifying hedging relationships and are, therefore, marked-to-market through earnings each period. Because the derivatives have mirror-image contractual terms, the changes in fair value substantially offset through earnings. The net effect on earnings is primarily driven by changes in the credit valuation adjustment (“CVA”). The CVA represents the dollar amount of fair value adjustment related to nonperformance risk of both the Bank and its counterparties. Fees earned in connection with the execution of derivatives related to this program are recognized in the consolidated statement of operations in other income. As of March 31, 2018 and December 31, 2017, the Bank had 148 and 142 derivatives, respectively, related to this program, comprised of interest rate swaps and caps, with an aggregate notional amount of $1.2 billion as of March 31, 2018 and $1.1 billion as of December 31, 2017. As of March 31, 2018, there were four foreign currency exchange contracts with an aggregate notional amount of $0.3 million outstanding related to this program, and as of December 31, 2017, there were three foreign currency exchange contracts with an aggregate notional amount of $0.2 million.

In addition, as a participant lender, the Bank has guaranteed performance on the pro-rated portion of swaps executed by other financial institutions. As the participant lender, the Bank is providing a partial guarantee, but is not a direct party to the related swap transactions. The Bank has no obligations under the risk participation agreements unless the borrower defaults on their swap transaction with the lead bank and the swap is in a liability position to the borrower. In that instance, the Bank has agreed to pay the lead bank a portion of the swap’s termination value at the time of the default. The derivative transactions entered into as part of these agreements are not designated, as per ASC 815, as qualifying hedging relationships and are, therefore, marked-to-market through earnings each period. As of March 31, 2018, there were seven of these risk participation transactions with an aggregate notional amount of $60.3 million and, as of December 31, 2017, there were six of these risk participation transactions with an aggregate notional amount of $48.0 million.

The Bank has also participated out to another financial institution a pro-rated portion of two swaps executed by the Bank. The other financial institution has no obligations under the risk participation agreements unless the borrowers default on their swap transactions with the Bank and the swaps are in liability positions to the borrower. In those instances, the other financial institution has agreed to pay the Bank a portion of the swap’s termination value at the time of the default. The derivative transactions entered into as part of these agreements are not designated, as per ASC 815, as qualifying hedging relationships and are, therefore, marked-to-market through earnings each period. The pro-rated notional amount of these risk participation transactions was $6.1 million as of both March 31, 2018 and December 31, 2017.

The following table presents the effect of the Bank’s derivative financial instruments not designated as hedging instruments in the consolidated statement of operations for the three months ended March 31, 2018 and 2017.

Effective tax rate attributable to the Company	22.8		%	33.0		%

The effective tax rate for continuing operations for the three months ended March 31, 2018 of 21.5%, with related tax expense of $6.0 million, was calculated based on a projected 2018 annual effective tax rate. The effective tax rate was more than the statutory rate of 21% due primarily to state and local income taxes and the accounting for investments in affordable housing projects. These items were partially offset by earnings from tax-exempt investments, income tax credits, and income attributable to noncontrolling interests.

The effective tax rate for continuing operations for the three months ended March 31, 2017 of 30.4%, with related tax expense of $6.6 million, was calculated based on a projected 2017 annual effective tax rate. The effective tax rate was less than the statutory rate of 35% due primarily to earnings from tax-exempt investments, income tax credits, and income attributable to noncontrolling interests. These items were partially offset by state and local income taxes.

The effective tax rate for continuing operations for the three months ended March 31, 2018 is lower than the effective tax rate for the same period in 2017 due primarily to the reduction in the federal corporate tax rate from 35% to 21% as a result of the Tax Cuts and Jobs Act (the “Tax Act”) that was enacted on December 22, 2017.

Noncontrolling Interests

Noncontrolling Interest [Abstract]

Noncontrolling Interest Disclosure [Text Block]

Noncontrolling Interests

At the Company, noncontrolling interests consist of equity owned by management of the Company’s respective majority-owned affiliates. Net income attributable to noncontrolling interests in the consolidated statements of operations represents the net income allocated to the noncontrolling interest owners of the affiliates. Net income allocated to the noncontrolling interest owners was $1.1 million and $1.0 million for the three-month periods ended March 31, 2018 and 2017, respectively.

On the consolidated balance sheets, noncontrolling interests are included as the sum of the capital and undistributed profits allocated to the noncontrolling interest owners. Typically, this balance is included in a company’s permanent shareholders’ equity in the consolidated balance sheets. When the noncontrolling interest owners’ rights include certain redemption features, as described in ASC 480, Distinguishing Liabilities from Equity, such redeemable noncontrolling interests are classified as mezzanine equity and are not included in permanent shareholders’ equity. Due to the redemption features of the noncontrolling interests, the Company had redeemable noncontrolling interests held in mezzanine equity in the accompanying consolidated balance sheets of $16.3 million and $17.5 million at March 31, 2018 and December 31, 2017, respectively. The aggregate amount of such redeemable noncontrolling equity interests are recorded at the estimated maximum redemption values. In addition, the Company had $4.8 million and $5.2 million in noncontrolling interests included in permanent shareholder’s equity at March 31, 2018 and December 31, 2017, respectively.

Each non-wholly owned affiliate operating agreement provides the Company and/or the noncontrolling interests with contingent call or put redemption features used for the orderly transfer of noncontrolling equity interests between the affiliate noncontrolling interest owners and the Company at either a contractually predetermined fair value; multiple of earnings before interest, taxes, depreciation, and amortization (EBITDA); or fair value. The Company may liquidate these noncontrolling interests in cash, shares of the Company’s common stock, or other forms of consideration dependent on the operating agreement. These agreements are discussed in Part II. Item 8. “Financial Statements and Supplementary Data - Note 14: Noncontrolling Interests” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Generally, these put and call redemption features refer to shareholder rights of both the Company and the noncontrolling interest owners of the Company’s majority-owned affiliate companies. The affiliate company noncontrolling interests generally take the form of limited liability company (LLC) units, profits interests, or common stock (collectively, the “noncontrolling equity interests”). In most circumstances, the put and call redemption features generally relate to the Company’s right and, in some cases, obligation to purchase and the noncontrolling equity interests’ right to sell their equity interests. There are various events that could cause the puts or calls to be exercised, such as a change in control, death, disability, retirement, resignation or termination. The puts and calls are generally to be exercised at the then fair value or a contractually agreed upon approximation thereof. The terms of these rights vary and are governed by the respective individual operating and legal documents.

The following table presents, by affiliate, the noncontrolling interests included as redeemable noncontrolling interests and noncontrolling interests in mezzanine and permanent equity, respectively, at the periods indicated:

Revenue Recognition (Notes)

Revenue Recognition [Abstract]

Revenue Recognition, Deferred Revenue [Policy Text Block]

Revenue Recognition

On January 1, 2018, the Company adopted ASU 2014-09 et al. As stated in Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 1: Basis of Presentation and Summary of Significant Accounting Policies,” the implementation of the new standard did not have a material impact on the measurement or recognition of revenue; as such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, Revenue from Contracts with Customers (“ASC 606”), while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting under ASC 605, Revenue Recognition.

ASC 606 does not apply to revenue associated with financial instruments, including interest income on loans and investment securities. In addition, certain noninterest income such as fees associated with mortgage servicing rights, late fees, BOLI income, and derivatives are also not in scope of the new guidance. ASC 606 is applicable to noninterest income such as investment management fees, wealth advisory fees, wealth management and trust fees, and certain banking fees. However, the recognition of this revenue did not change upon adoption of ASC 606. Substantially all of the Company’s revenue is generated from contracts with customers. Noninterest income considered in-scope of ASC 606 is discussed below.

Investment management fees

Investment management fees are earned for the management of a series of accounts and funds in which clients invest directly, acting as a sub-advisor to larger investment management companies, or private client account management. The Company’s performance obligation is satisfied over time and the resulting fees are recognized monthly, based upon either the beginning-of quarter (in advance) or quarter-end (in arrears) market value of the assets under management and the applicable fee rate, depending on the terms of the contract. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company may earn performance-based incentives on certain contracts. Receivables are recorded on the consolidated balance sheet in the fees receivable line item.

All of the investment management fee income on the consolidated statement of operations for the three months ended March 31, 2018 is considered in-scope of ASC 606.

Wealth advisory fees

Wealth advisory fees are earned for providing financial advisory services to clients. The Company’s performance obligation under these contracts is satisfied over time as the financial advisory services are provided. Fees are recognized monthly based either on a fixed fee amount or are based on the quarter-end (in arrears) market value of the assets under management and the applicable fee rate (“asset based fees”), depending on the terms of the contract. Payment on fixed fee contracts is received based on a schedule outlined in the contract, while payment on asset based fees are generally received a few days after quarter end through a direct charge to customers’ accounts. No performance based incentives are earned on wealth advisory contracts. Receivables are recorded on the consolidated balance sheet in the fees receivable line item. Deferred revenues related to the fixed fee contracts of $6.2 million and $6.6 million at March 31, 2018 and December 31, 2017, respectively, are recorded on the consolidated balance sheet within the other liabilities line item.

All of the wealth advisory fee income on the consolidated statement of operations for the three months ended March 31, 2018 is considered in-scope of ASC 606.

Wealth management and trust fees

Wealth management fees are earned for providing investment management, retirement plan advisory, family office, and financial planning services to clients. The Company’s performance obligation under these contracts is satisfied over time as the wealth management services are provided. Fees are recognized monthly based on the average monthly, beginning-of-quarter, or, for a small number of clients, end-of-quarter market value of the assets under management and the applicable fee rate, depending on the terms of the contract. No performance based incentives are earned on wealth management contracts. Receivables are recorded on the consolidated balance sheet in the fees receivable line item.

Trust fees are earned when the Company is appointed as trustee for clients. As trustee, the Company administers the client’s trust and manages the assets of the trust including investments and property. The Company’s performance obligation under these agreements is satisfied over time as the administration and management services are provided. Fees are recognized monthly based on a percentage of the market value of the account as outlined in the agreement. Payment frequency is defined in the individual contracts which primarily stipulate monthly in arrears. No performance based incentives are earned on trust fee contracts. Receivables are recorded on the consolidated balance sheet in the fees receivable line item.

All of the wealth management and trust fee income on the consolidated statement of operations for the three months ended March 31, 2018 is considered in-scope of ASC 606.

Other banking fee income

The Bank charges a variety of fees to its clients for services provided on the deposit and deposit management related accounts. Each fee is either transaction-based or assessed monthly. The types of fees include service charges on accounts, overdraft fees, maintenance fees, ATM fee charges, credit card charges, and other miscellaneous charges related to the accounts. These fees are not governed by individual contracts with clients. They are charges to clients based on disclosures presented to clients upon opening these accounts along with updated disclosures when changes are made to the fee structures. The transaction-based fees are recognized in revenue when charged to the client based on specific activity on the client’s account. Monthly service/maintenance charges are recognized in the month they are earned and are charged directly to the client’s account.

The Bank also charges fees for treasury activities such as foreign exchange fees for clients with a banking relationship. These fees are recorded when earned via completion of the transaction for the client. The completion of the transaction is deemed to be the performance obligation of the transaction. The related revenue is recorded through a direct charge to the client’s account. There are no individual agreements or contracts with clients as it relates to foreign exchange fees as they are governed by client disclosure statements and the Bank’s internal policies and procedures.

For both three month periods ended March 31, 2018 and 2017, $0.9 million of other banking fee income as described above is considered in-scope for ASC 606.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Description of New Accounting Pronouncements Not yet Adopted [Text Block]

Recent Accounting Pronouncements

In May 2014 and at various other dates after May 14, the FASB issued ASU 2014-09 et al. Under the new standard, a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. ASU 2014-09 et al. does not apply to revenue associated with financial instruments such as loans and securities. On January 1, 2018, we adopted ASU 2014-09 et al. using the modified retrospective transition method, however no cumulative effect adjustment to opening retained earnings as of January 1, 2018 was required. For additional disclosure details, see Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 1: Basis of Presentation and Summary of Significant Accounting Policies and Note 13: Revenue Recognition.”

In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Instruments - Going Concern (“ASU 2014-15”). ASU 2014-15 requires management to evaluate an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Management must evaluate whether conditions and events raise substantial doubt about an entity’s ability to continue as a going concern and then whether its plans alleviate that doubt. ASU 2014-15 was effective in 2016 and management performed the required evaluation and concluded that there were no such conditions or events that raised substantial doubt about the Company’s ability to continue as a going concern.

In January 2016, the FASB issued ASU 2016-01. This ASU requires equity investments to be measured at fair value with changes in fair value, net of tax, recognized in net income. As a result of implementing this standard, the Company reclassified $339 thousand in unrealized gains on available-for-sale equity investments, net of tax, from accumulated other comprehensive income to retained earnings as of January 1, 2018.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This ASU update amends current lease accounting and requires all leases, other than short-term leases, to be reported on the balance sheet through the recognition of a right-of-use asset and a corresponding liability for future lease obligations. The amended guidance will be effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods and will require transition utilizing a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption of this ASU is permitted although the Company does not plan to early adopt. The Company does not anticipate a material impact to revenue or operating expenses as a result of the adoption of this ASU. The Company expects that this ASU will gross up the assets and liabilities on the balance sheet related to the lease assets and liabilities and reduce regulatory capital ratios.

In March 2016, the FASB issued ASU 2016-09, Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This update is intended to simplify several aspects of the accounting for employee share-based plans such as income tax consequences, classification of awards as either liabilities or equity on the balance sheet, and classification on the statement of cash flows. This ASU was effective for fiscal years beginning after December 15, 2016, including interim periods within those years. The Company adopted this ASU on January 1, 2017. The adoption of this ASU has resulted in, and will continue to result in, fluctuations in the Company’s earnings due to changes in the Company’s stock price between issuance date and settlement date of employee share-based transactions. In addition, the Company anticipates that certain stock options will expire unexercised, due to being out of the money, and this ASU requires the previous tax benefits to be reversed.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments (Topic 326) (“ASU 2016-13”). This update is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This ASU will be effective for fiscal years beginning after December 15, 2019. Early adoption is available as of the fiscal year beginning after December 15, 2018. The Company does not plan on adopting early. The impact of this ASU on the Company’s consolidated financial statements will depend on factors at the time of adoption such as the balance and type of loans on the balance sheet, the Company’s loan loss history, and various qualitative factors.

In August 2016, the FASB issued ASU 2016-15.  This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. This ASU is effective for the Company beginning on January 1, 2018. Early adoption was permitted, provided that all of the amendments are adopted in the same period, however the Company did not early adopt. The guidance requires application using a retrospective transition method. This ASU did not have an impact on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU 2017-07. This amendment requires an employer to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. As a result of the adoption of this ASU, $160 thousand has been reclassified from salaries and employee benefits expense to other expense within the Company’s consolidated statement of operations for the three months ended March 31, 2017. For the three months ended March 31, 2018, $135 thousand is presented within other expense that would have been presented within salaries and employee benefits prior to adoption of ASU 2017-07.

In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities (“ASU 2017-08”). This update amends the amortization period for certain purchased callable debt securities held at a premium. The amortization period for the premium on such securities is being shortened to the earliest call date. Under current GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument. ASU 2017-08 is effective for fiscal years beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, including in an interim period. The guidance requires application using a modified retrospective transition method through a cumulative-effect adjustment to beginning retained earnings. The Company early adopted this ASU as of July 1, 2017, which had a minimal impact on the consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12. The standard is intended to improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities by better aligning the entity’s financial reporting for hedging relationships with those risk management activities and to reduce the complexity of and simplify the application of hedge accounting by preparers. ASU No. 2017-12 is effective for interim and annual reporting periods beginning after December 15, 2018; early adoption is permitted. The Company elected to early adopt this ASU as of January 1, 2018 with a modified retrospective transition. As a result of implementing this standard, the Company reclassified $5 thousand in unrealized losses on derivatives from accumulated other comprehensive income to retained earnings as of January 1, 2018. This ASU will provide more flexibility in the Company’s risk management activities and we believe it will enhance the Company’s ability to employ risk management strategies, while improving the transparency and understanding of those strategies for financial statement users.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This update was issued to address a narrow-scope financial reporting issue that arose as a consequence of the change in the tax law. On December 22, 2017, the U.S. federal government enacted the Tax Act which, among other significant changes, lowers the federal corporate tax rate from 35% to 21% effective January 1, 2018. This update requires a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the enactment of the Tax Act. ASC 740 requires that the tax effects of changes in tax rates be recognized in income tax expense/ (benefit) attributable to continuing operations in the period in which the law is enacted. As a result, the tax effect of accumulated other comprehensive income does not reflect the appropriate tax rate. The amendments in this ASU eliminate the stranded tax effects associated with the change in the federal corporate income tax rate related to the Tax Act and improve the usefulness of information reported to financial statement users. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those years. Early adoption is permitted for public business entities for reporting periods for which financial statements have not yet been issued. The Company early adopted this ASU on December 31, 2017 and reclassified $1.5 million from accumulated other comprehensive income to retained earnings.

Subsequent Events [Abstract]

Subsequent Events [Text Block]

Subsequent Event

In April 2018, the Company completed the sale of its ownership interest in Anchor. Anchor’s results remain consolidated in the Company’s results during current and prior periods. The transaction had previously been announced in December 2017. The Company classified the assets and liabilities of Anchor as held for sale at March 31, 2018 and December 31, 2017, which are included with other assets and other liabilities, respectively, on the Company’s consolidated balance sheets.

As a result of the transaction, Boston Private received approximately $32 million of cash and will receive future revenue share payments that have a net present value of approximately $15 million. During the second quarter, the Company will recognize a tax expense of approximately $11 million to $12 million attributable to the transaction, which is primarily the result of a book to tax basis difference associated with nondeductible goodwill. The net financial impact will increase the Company’s Tier 1 common equity by approximately $34 million to $35 million. Accordingly, the results of Anchor after the completion of the sale in April 2018 will not be included in the results of the Company.

Basis of Presentation and Summary of Significant Accounting Policies [Abstract]

New Accounting Pronouncements, Policy [Policy Text Block]

For interim reporting purposes, the Company follows the same significant accounting policies, except for the following new accounting pronouncements from the Financial Accounting Standards Board (the “FASB”) that were adopted effective January 1, 2018:

• Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”). As a result of implementing this standard, the Company reclassified $5 thousand in unrealized losses on derivatives related to hedge ineffectiveness from accumulated other comprehensive income to retained earnings as of January 1, 2018. This ASU will provide more flexibility in the Company’s risk management activities and we believe it will enhance the Company’s ability to employ risk management strategies, while improving the transparency and understanding of those strategies for financial statement users.

• ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (“ASU 2017-07”). This amendment requires an employer to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. As a result of the retrospective adoption of this ASU, $160 thousand for the three months ended March 31, 2017 has been reclassified from salaries and employee benefits expense to other expense within the Company’s consolidated statement of operations. For the three months ended March 31, 2018, $135 thousand is presented within other expense that would have been presented within salaries and employee benefits prior to adoption of ASU 2017-07.

• ASU 2016-15, Statement of Cash Flows (Topic 230) (“ASU 2016-15”).  This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. This ASU is effective for the Company beginning on January 1, 2018. The guidance requires application using a retrospective transition method. This ASU did not have an impact on the Company’s consolidated financial statements.

• ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). This amendment requires equity investments to be measured at fair value with changes in fair value, net of tax, recognized in net income. As a result of implementing this standard, the Company reclassified $339 thousand in unrealized gains on available-for-sale equity investments, net of tax, from accumulated other comprehensive income to retained earnings as of January 1, 2018.

• ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which was subsequently amended by additional ASUs, including ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) and ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, collectively, “ASU 2014-09 et al.” ASU 2014-09 et al. was adopted using the modified retrospective transition method as of January 1, 2018, however no cumulative effect adjustment was required. This new guidance was applied to all revenue contracts in place at the date of adoption. See Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 13: Revenue Recognition” for further details.

In accordance with the FASB Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”), an increase in redemption value from period to period reduces income attributable to common shareholders. Decreases in redemption value from period to period increase income attributable to common shareholders, but only to the extent that the cumulative change in redemption value remains a cumulative increase since adoption of this standard in the first quarter of 2009.

(1) There was an additional $(4) thousand loss related to the ineffective portion for the three months ended as of March 31, 2017. The guidance in ASU 2017-12 requires that amounts in accumulated other comprehensive income that are included in the assessment of effectiveness should be reclassified into earnings in the same period in which the hedged forecasted transactions impact earnings. Transition guidance for this ASU further states that upon adoption, previously recorded cumulative ineffectiveness for cash flow hedges existing at the adoption date be eliminated by means of a cumulative-effect adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the initial application date. There was a $5 thousand reclassification related to the adoption of ASU 2017-12 effective January 1, 2018.

In accordance with the FASB Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”), an increase in redemption value from period to period reduces income attributable to common shareholders. Decreases in redemption value from period to period increase income attributable to common shareholders, but only to the extent that the cumulative change in redemption value remains a cumulative increase since adoption of this standard in the first quarter of 2009.

[1] There was an additional $(4) thousand loss related to the ineffective portion for the three months ended as of March 31, 2017. The guidance in ASU 2017-12 requires that amounts in accumulated other comprehensive income that are included in the assessment of effectiveness should be reclassified into earnings in the same period in which the hedged forecasted transactions impact earnings. Transition guidance for this ASU further states that upon adoption, previously recorded cumulative ineffectiveness for cash flow hedges existing at the adoption date be eliminated by means of a cumulative-effect adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the initial application date. There was a $5 thousand reclassification related to the adoption of ASU 2017-12 effective January 1, 2018.
