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, 2015 for a description of the redemption values related to the redeemable noncontrolling interests. In accordance with the Financial Accounting Standards Board (“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 Company presents its EPS based on the treasury stock method. The Company reverted to the treasury stock presentation from the two-class presentation due to the immaterial number of participating shares outstanding as of March 31, 2016. If the EPS presentation had been based on the two-class method, the following adjustments would have been made to the presentation of EPS for the three and nine months ended September 30, 2016 . Net income attributable to common shareholders would have been reduced by an additional $4 thousand , for the nine months ended September 30, 2016 , with no change for the three month period then ended. The allocation of net income to participating securities would have been $1 thousand and $7 thousand , for the three and nine months ended September 30, 2016 , respectively, reducing net income attributable to common shareholders by a total of $1 thousand and $11 thousand , for the three and nine months ended September 30, 2016 , respectively. Basic EPS would not change. Weighted average diluted shared outstanding would have been reduced by 3,809 shares and 13,477 shares for the three and nine months ended September 30, 2016 , respectively. Diluted EPS would not change. If the EPS presentation had been based on the two-class method, the following adjustments would have been made to the presentation of EPS for the three and nine months ended September 30, 2015 . Net income attributable to common shareholders would have been reduced by an additional $5 thousand and $85 thousand , for the three and nine months ended September 30, 2015 , respectively, and the allocation of net income to participating securities would have been $8 thousand and $91 thousand , for the three and nine months ended September 30, 2015 , respectively, reducing net income attributable to common shareholders by a total of $13 thousand and $176 thousand , for the three and nine months ended September 30, 2015 , respectively. Basic EPS would decrease by $0.01 per share for the nine months ended September 30, 2015 , with no change for the three months ended September 30, 2015. Weighted average diluted shares outstanding would have been reduced by 69,218 shares and 211,108 shares , for the three and nine months ended September 30, 2015 , respectively. Diluted EPS would not change. (3) The diluted EPS computations for the three and nine months ended September 30, 2016 and 2015 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 September 30, Nine months ended September 30, 2016 2015 2016 2015 Shares excluded due to exercise price exceeding the average market price of common shares during the period (total outstanding): (In thousands) Potential common shares from: Stock options, restricted stock, or other dilutive securities 224 508 285 559 Total shares excluded due to exercise price exceeding the average market price of common shares during the period 224 508 285 559

Certain securities are callable before their final maturity. Additionally, certain securities (such as mortgage-backed securities) are shown within the table below based on their final (contractual) maturity, but due to prepayments and amortization are expected to have shorter lives.

The U.S. government and agencies securities, and mortgage-backed securities in the table above had current Standard and Poor’s credit ratings of AA+. The municipal bonds in the table above had current Standard and Poor’s credit ratings of at least AA-. The other securities consisted of equity securities. At September 30, 2016 , 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 September 30, 2016 and 2015 , 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. The Company has no intent to sell any securities in an unrealized loss position at September 30, 2016 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. Subsequent to September 30, 2016 and through the date of the filing of this Quarterly Report on Form 10-Q, no securities were downgraded to below investment grade, nor were any securities in an unrealized loss position sold. 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 September 30, 2016 or December 31, 2015 . 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 $35.4 million and $27.7 million in cost method investments included in other assets as of September 30, 2016 and December 31, 2015 , respectively.

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 September 30, 2016 and December 31, 2015 , aggregated by the level in the fair value hierarchy within which those measurements fall: As of September 30, 2016 Fair value measurements at reporting date using: Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) (In thousands) Assets: Available-for-sale securities: U.S. government and agencies $ 41,343 $ 40,694 $ 649 $ — Government-sponsored entities 324,712 — 324,712 — Municipal bonds 284,635 — 284,635 — Mortgage-backed securities 576,850 — 576,850 — Other 22,038 22,038 — — Total available-for-sale securities 1,249,578 62,732 1,186,846 — Derivatives - interest rate customer swaps 29,198 — 29,198 — Derivatives - risk participation agreement 40 — 40 — Other investments 6,141 6,141 — — Liabilities: Derivatives - interest rate customer swaps $ 30,257 $ — $ 30,257 $ — Derivatives - interest rate swaps 2,542 — 2,542 — Derivatives - risk participation agreement 30 — 30 — Other liabilities 6,141 6,141 — — Fair value measurements at reporting date using: As of December 31, 2015 Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) (In thousands) Assets: Available-for-sale securities: U.S. government and agencies $ 21,251 $ 20,251 $ 1,000 $ — Government-sponsored entities 344,562 — 344,562 — Municipal bonds 268,644 — 268,644 — Mortgage-backed securities 427,041 — 427,041 — Other 23,012 23,012 — — Total available-for-sale securities 1,084,510 43,263 1,041,247 — Derivatives - interest rate customer swaps 7,960 — 7,960 — Other investments 5,602 5,602 — — Liabilities: Derivatives - interest rate customer swaps $ 8,084 $ — $ 8,084 $ — Derivatives - interest rate swaps 1,907 — 1,907 — Derivatives - risk participation agreement 11 — 11 — Other liabilities 5,602 5,602 — — As of September 30, 2016 and December 31, 2015 , available-for-sale securities consisted primarily of U.S. government and agencies securities, government-sponsored entities securities, municipal bonds, mortgage-backed securities, and other available-for-sale securities. The equities (which are categorized as other available-for-sale securities) are valued with prices quoted in active markets. Five U.S. Treasury securities at September 30, 2016 and three U.S. Treasury securities at December 31, 2015 , are valued with prices quoted in active markets. Therefore, they have been categorized as a Level 1 measurement. The government-sponsored entities securities, municipal bonds, mortgage-backed securities, and certain investments in Small Business Administration (“SBA”) loans (which are categorized as U.S. government and agencies securities) generally have quoted prices but are traded less frequently than exchange-traded securities and can be priced using market data from similar assets. Therefore, they have been categorized as a Level 2 measurement. No investments held at September 30, 2016 or December 31, 2015 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 and nine month periods ended September 30, 2016 or 2015. The Company uses interest rate customer swaps, interest rate swaps, risk participation agreements, and a junior subordinated debenture interest rate swap to manage its interest rate risk, and customer foreign exchange forward contracts to manage its foreign exchange risk, if any. The junior subordinated debenture interest rate swap agreement matured on December 30, 2015. 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. Therefore, they have been categorized as a Level 2 measurement as of September 30, 2016 and December 31, 2015 . 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 September 30, 2016 and December 31, 2015 . Other investments, which are not considered available-for-sale investments, consist of deferred compensation trusts, which consist of publicly traded mutual fund investments that are valued at prices quoted in active markets. Therefore, they have been categorized as a Level 1 measurement as of September 30, 2016 and December 31, 2015 . There were no transfers between levels for assets or liabilities recorded at fair value on a recurring basis during the three and nine month periods ended September 30, 2016 and 2015 . There were no Level 3 assets valued on a recurring basis at September 30, 2016 or December 31, 2015 . The following tables present the Company’s assets and liabilities measured at fair value on a non-recurring basis during the periods ended September 30, 2016 and 2015 , respectively, aggregated by the level in the fair value hierarchy within which those measurements fall: As of September 30, 2016 Fair value measurements at reporting date using: Gain (losses) from fair value changes Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) Three months ended September 30, 2016 Nine months ended September 30, 2016 (In thousands) Assets: Impaired loans (1) $ 11,936 $ — $ — $ 11,936 $ (418 ) $ (2,098 ) _____________________ (1) Collateral-dependent impaired loans held at September 30, 2016 that had write-downs in fair value or whose specific reserve changed during the first nine months of 2016 . As of September 30, 2015 Fair value measurements at reporting date using: Gain (losses) from fair value changes Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) Three months ended September 30, 2015 Nine months ended September 30, 2015 (In thousands) Assets: Impaired loans (1) $ 6,704 $ — $ — $ 6,704 $ (2,504 ) $ (2,504 ) _____________________ (1) Collateral-dependent impaired loans held at September 30, 2015 that had write-downs in fair value or whose specific reserve changed during the first nine months of 2015 . The following tables present 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 September 30, 2016 Fair Value Valuation technique Unobservable Input Range of Inputs Utilized Weighted Average of Inputs Utilized (In thousands) Impaired Loans $ 11,936 Appraisals of Collateral Discount for costs to sell 5% - 78% 5% Appraisal adjustments 0% - 20% 16% As of September 30, 2015 Fair Value Valuation technique Unobservable Input Range of Inputs Utilized Weighted Average of Inputs Utilized (In thousands) Impaired Loans $ 6,704 Appraisals of Collateral Discount for costs to sell 7% - 22% 15% Appraisal adjustments 0% - 25% 7% 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 (other than certain loans, as noted below): As of September 30, 2016 Book Value Fair Value Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) (In thousands) FINANCIAL ASSETS: Cash and cash equivalents $ 67,631 $ 67,631 $ 67,631 $ — $ — Held-to-maturity investment securities 98,881 100,509 — 100,509 — Loans held for sale 5,316 5,404 — 5,404 — Loans, net 5,791,829 5,870,480 — — 5,870,480 Other financial assets 119,904 119,904 — 119,904 — FINANCIAL LIABILITIES: Deposits 5,812,243 5,814,016 — 5,814,016 — Deposits held for sale 105,788 102,846 — 102,846 — Securities sold under agreements to repurchase 77,466 77,466 — 77,466 — Federal Funds purchased 125,000 125,000 — 125,000 — Federal Home Loan Bank borrowings 522,681 527,266 — 527,266 — Junior subordinated debentures 106,363 96,363 — — 96,363 Other financial liabilities 1,978 1,978 — 1,978 — As of December 31, 2015 Book Value Fair Value Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) (In thousands) FINANCIAL ASSETS: Cash and cash equivalents $ 238,694 $ 238,694 $ 238,694 $ — $ — Held-to-maturity investment securities 116,352 116,384 — 116,384 — Loans held for sale 8,072 8,144 — 8,144 — Loans, net 5,640,712 5,658,254 — — 5,658,254 Other financial assets 118,233 118,233 — 118,233 — FINANCIAL LIABILITIES: Deposits 6,040,437 6,041,239 — 6,041,239 — Securities sold under agreements to repurchase 58,215 58,215 — 58,215 — Federal Home Loan Bank borrowings 461,324 465,100 — 465,100 — Junior subordinated debentures 106,363 96,363 — — 96,363 Other financial liabilities 1,978 1,978 — 1,978 — The estimated fair values have been determined by using available quoted market information or other appropriate valuation methodologies. The aggregate fair value amounts presented do not represent the underlying value of the Company taken as a whole. An excess of fair value over book value on financial assets represents a premium, or gain, the Company might recognize if the asset 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 liability were sold. Conversely, losses would be recognized if an asset was sold where the book value exceeded the fair value or a liability was 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 sheets 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. All held-to-maturity 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 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. The method of estimating the fair value of the loans disclosed in the table above does not incorporate the exit price concept in the presentation of the fair value of these financial instruments. 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, stock in Federal Home Loan Banks (“FHLBs”), other assets held for sale, and the cash surrender value of bank-owned life insurance, 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 sheets 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. Deposits held for sale The deposits held for sale at September 30, 2016 relate to the two banking offices in Southern California for which the Bank has entered into a Purchase and Assumption Agreement (the “Agreement”). Pursuant to this Agreement, the Bank will transfer certain depository accounts of these offices to the purchaser. The fair value reported for deposits held for sale was estimated based on the deposit premium to be paid by the acquirer per the Agreement and the amount and type of deposits outstanding as of September 30, 2016. The actual premium will be updated based on the average deposits prior to the close. Accordingly, deposits held for sale are included in the Level 2 fair value category. 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 therefore these securities 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 consist 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.

Loans and Leases Receivable Disclosure [Abstract]
Financing Receivables [Text Block]	Loan Portfolio and Credit Quality The Bank’s lending activities are conducted principally in the regions of New England, San Francisco Bay Area, and Southern California. The Bank originates single and multi-family residential loans, commercial real estate loans, commercial and industrial 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, San Francisco Bay Area, and Southern California economies and real estate markets. Total loans include deferred loan origination (fees)/ costs, net, of $6.3 million and $5.6 million as of September 30, 2016 and December 31, 2015 , respectively. The following table presents a summary of the loan portfolio based on the portfolio segment as of the dates indicated: September 30, December 31, 2015 (In thousands) Commercial and industrial $ 1,099,170 $ 1,111,555 Commercial real estate 2,054,570 1,914,134 Construction and land 98,696 183,434 Residential 2,316,090 2,229,540 Home equity 121,269 119,828 Consumer and other 179,703 160,721 Total Loans $ 5,869,498 $ 5,719,212 The following table presents nonaccrual loans receivable by class of receivable as of the dates indicated: September 30, December 31, 2015 (In thousands) Commercial and industrial $ 927 $ 1,019 Commercial real estate 5,138 11,232 Construction and land 224 3,297 Residential 9,060 9,661 Home equity 1,075 1,306 Consumer and other 67 56 Total $ 16,491 $ 26,571 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 September 30, 2016 and December 31, 2015 . 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 by class of receivable as of the dates indicated: September 30, 2016 Accruing Past Due Nonaccrual Loans 30-59 Days Past Due 60-89 Days Past Due Total Accruing Past Due Current Payment Status 30-89 Days Past Due 90 Days or Greater Past Due Total Non-Accrual Loans Current Accruing Loans Total Loans Receivable (In thousands) Commercial and industrial $ 524 $ 836 $ 1,360 $ 909 $ — $ 18 $ 927 $ 1,096,883 $ 1,099,170 Commercial real estate 2,200 244 2,444 3,488 213 1,437 5,138 2,046,988 2,054,570 Construction and land — — — 34 20 170 224 98,472 98,696 Residential — 663 663 2,765 1,360 4,935 9,060 2,306,367 2,316,090 Home equity — — — — 83 992 1,075 120,194 121,269 Consumer and other 107 15 122 — — 67 67 179,514 179,703 Total $ 2,831 $ 1,758 $ 4,589 $ 7,196 $ 1,676 $ 7,619 $ 16,491 $ 5,848,418 $ 5,869,498 December 31, 2015 Accruing Past Due Nonaccrual Loans 30-59 Days Past Due 60-89 Days Past Due Total Accruing Past Due Current Payment Status 30-89 Days Past Due 90 Days or Greater Past Due Total Non-Accrual Loans Current Accruing Loans Total Loans Receivable (In thousands) Commercial and industrial $ 2,329 $ 338 $ 2,667 $ 726 $ — $ 293 $ 1,019 $ 1,107,869 $ 1,111,555 Commercial real estate 2,091 529 2,620 5,912 — 5,320 11,232 1,900,282 1,914,134 Construction and land — — — 149 34 3,114 3,297 180,137 183,434 Residential 6,267 873 7,140 924 874 7,863 9,661 2,212,739 2,229,540 Home equity 40 — 40 217 — 1,089 1,306 118,482 119,828 Consumer and other 235 392 627 24 9 23 56 160,038 160,721 Total $ 10,962 $ 2,132 $ 13,094 $ 7,952 $ 917 $ 17,702 $ 26,571 $ 5,679,547 $ 5,719,212 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. 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, 2015, 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. Generally, only commercial loans, including commercial real estate, commercial and industrial loans, and construction and land loans are given a numerical grade. 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.

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 September 30, 2016 and December 31, 2015 , TDRs totaled $30.6 million . As of September 30, 2016 , $26.1 million of the $30.6 million in TDRs were on accrual status. As of December 31, 2015 , $18.6 million of the $30.6 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. The following tables present the balance of TDRs that were restructured or defaulted during the periods indicated and the types of concessions granted: As of and for the three months ended September 30, 2016 Restructured current quarter TDRs that defaulted in the # of Loans Pre- modification recorded investment Post- modification recorded investment # of Loans Post- modification recorded investment (Dollars in thousands) Commercial and industrial — $ — $ — — $ — Commercial real estate — — — 1 1,276 Construction and land — — — — — Residential — — — — — Home equity — — — — — Consumer and other — — — — — Total — $ — $ — 1 $ 1,276 As of and for the nine months ended September 30, 2016 Restructured year to date TDRs that defaulted # of Loans Pre- modification recorded investment Post- modification recorded investment # of Loans Post- modification recorded investment (Dollars in thousands) Commercial and industrial 3 $ 7,384 $ 7,209 — $ — Commercial real estate 1 1,276 1,276 1 1,276 Construction and land — — — — — Residential 2 260 261 — — Home equity — — — — — Consumer and other — — — — — Total 6 $ 8,920 $ 8,746 1 $ 1,276 As of and for the nine months ended September 30, 2016 Extension of term Temporary rate reduction Payment deferral Combination of concessions (1) Total concessions # of Post- cation ment # of Post- # of Post- # of Post- # of Post- (Dollars in thousands) Commercial and industrial 2 $ 7,209 — $ — — $ — 1 $ — 3 $ 7,209 Commercial real estate — — — — — — 1 1,276 1 1,276 Construction and land — — — — — — — — — — Residential — — 2 261 — — — — 2 261 Home equity — — — — — — — — — — Consumer and other — — — — — — — — — — _____________________ (1) Combination of concessions includes loans that have had more than one modification, including extension of term, temporary reduction of interest rate, and/or payment deferral.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	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. 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 September 30, 2016 and December 31, 2015 : September 30, 2016 December 31, 2015 Asset derivatives Liability derivatives Asset derivatives Liability derivatives Balance sheet location Fair value (1) Balance sheet location Fair value (1) Balance sheet location Fair value (1) Balance sheet location Fair value (1) (In thousands) Derivatives designated as hedging instruments: Interest rate products Other assets $ — Other liabilities $ (2,542 ) Other assets $ — Other liabilities $ (1,907 ) Derivatives not designated as hedging instruments: Interest rate products Other assets 29,198 Other liabilities (30,257 ) Other assets 7,960 Other liabilities (8,084 ) Risk participation agreements Other assets 40 Other liabilities (30 ) Other assets — Other liabilities (11 ) Total $ 29,238 $ (32,829 ) $ 7,960 $ (10,002 ) _____________________ (1) For additional details, see Part I.

The Bank was in compliance with these provisions as of September 30, 2016 and December 31, 2015 . 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 September 30, 2016 and December 31, 2015 . 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 September 30, 2016 and December 31, 2015 . As of September 30, 2016 and December 31, 2015 , the termination amounts related to collateral determinations of derivatives in a liability position were $32.7 million and $9.7 million , respectively. The Company has minimum collateral posting thresholds with its derivative counterparties and pledged securities with market values of $36.2 million and $9.8 million , respectively, as of September 30, 2016 and December 31, 2015 , against its obligations under these agreements. In addition, as of December 31, 2015, the Company had posted cash collateral of $2.0 million 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 objective in using derivatives is to add stability to interest income and expense and to manage the risk related to exposure to changes in interest rates. To accomplish this objective, the Bank entered into a total of six interest rate swaps, one during 2014 with an effective date of June 1, 2014, and five during 2013 with effective dates of December 1, 2014, September 2, 2014, June 1, 2014, March 1, 2014, and August 1, 2013. The six interest rate swaps each have a notional amount of $25 million and have terms ranging from three to six years. The Bank’s risk management objective and strategy for these interest rate swaps is to reduce its exposure to variability in interest-related cash outflows attributable to changes in the London Interbank Offered Rate (“LIBOR”) swap rate associated with borrowing programs for each of the periods, initially expected to be accomplished with LIBOR-indexed brokered deposits, but may also include LIBOR-indexed FHLB advances. The interest rate swaps will effectively fix the Bank’s interest payments on $150 million of its LIBOR-indexed liabilities at rates between 1.17% and 2.32%, and a weighted average rate of 1.85%. The Company uses 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 assesses 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 is 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 is recorded as a gain or loss in the consolidated statement of operations as part of fees and other income. There was an immaterial amount of hedge ineffectiveness during the three and nine months ended September 30, 2016 and no hedge ineffectiveness during the three and nine months ended September 30, 2015 . The Company monitors the risk of counterparty default on an ongoing basis. A portion of the balance reported in accumulated other comprehensive income related to derivatives will be reclassified to interest income or expense as interest payments are made or received on the Company’s interest rate swaps. During the next twelve months, the Company estimates that $1.3 million will be reclassified as an increase in interest expense. Non-designated Hedges Derivatives not designated as hedges are not speculative and result from two 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 nonperfomance 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 September 30, 2016 and December 31, 2015 , the Bank had 130 and 76 derivatives, respectively, related to this program, comprised of interest rate swaps and caps, with an aggregate notional amount of $1.0 billion and $475.3 million , respectively. There were no foreign currency exchange contracts outstanding related to this program as of both September 30, 2016 and December 31, 2015. In addition, as a participant lender, the Bank has guaranteed performance on the pro-rated portion of two 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. The pro-rated notional amount of these risk participation transactions was $13.3 million as of September 30, 2016 and $8.3 million as of December 31, 2015. 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 September 30, 2016. There were no risk participation agreements participated out as of December 31, 2015. 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 and nine months ended September 30, 2016 and 2015 .

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 nine months ended September 30, 2015 of 33.8% , with related tax expense of $24.8 million , was calculated based on a projected 2015 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 and an out-of-period adjustment related to non-deductible executive compensation, as described in more detail below. The effective tax rate for continuing operations for the nine months ended September 30, 2016 is lower than the effective tax rate for the same period in 2015 due primarily to an out-of-period adjustment recorded during the third quarter of 2015. The Company reevaluated its executive compensation plans during the third quarter of 2015 and discovered that certain executive compensation that was previously treated as fully deductible was non-deductible. The correction resulted in $1.8 million of additional tax expense that was related to prior years. After evaluating the quantitative and qualitative aspects of the correction, the Company determined that previously issued quarterly and annual consolidated financial statements were not materially misstated and, as a result, recorded the correction in the third quarter of 2015.

Noncontrolling Interests

Noncontrolling Interest [Abstract]
Noncontrolling Interest Disclosure [Text Block]	Noncontrolling Interests At the Company, noncontrolling interests typically 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 September 30, 2016 and 2015 , respectively, and $3.0 million and $3.5 million for the nine month periods ended September 30, 2016 and 2015 , 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 $16.2 million and $18.1 million at September 30, 2016 and December 31, 2015 , respectively. The aggregate amount of such redeemable noncontrolling equity interests are recorded at the estimated maximum redemption values. In addition, the Company had $3.8 million and $3.4 million in noncontrolling interests included in permanent shareholder’s equity at September 30, 2016 and December 31, 2015 , 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, 2015 . 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.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Recent Accounting Pronouncements In January 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-04, Receivables - Troubled Debt Restructuring by Creditors (Subtopic 310-40) - Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure . The amendments to this update are intended to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014 and interim periods within annual periods beginning after December 15, 2015. The adoption of this ASU did not have a material effect on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), amending the ASC and creating a new Topic 606, Revenue from Contracts with Customers. This issuance was part of the joint project between the FASB and the International Accounting Standards Board to clarify the principles of recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The impact of ASU 2014-09 on the Company’s consolidated financial statements is not yet known. Additionally, ASU 2015-14, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”) was issued in August 2015 which defers adoption to annual reporting periods beginning after December 15, 2017. 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 is effective for fiscal years beginning after December 15, 2016, including interim periods within those years. Although early adoption is permitted, the Company does not plan on adopting prior to 2017. The Company does not expect that this ASU will have a material effect on its consolidated financial statements although fluctuations in the Company’s stock price between issuance date and settlement date of employee share-based transactions will lead to fluctuations in earnings once this ASU is implemented. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . This ASU update is intended to increase transparency and comparability among companies by recognizing right of use lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods and is to be implemented utilizing a modified retrospective approach. The Company expects that this ASU will gross up the assets and liabilities on the balance sheet related to the lease assets and liabilities. 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 Company is currently evaluating the impact of this ASU on its consolidated financial statements. In August 2016, the FASB issued 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 fiscal years beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted, provided that all of the amendments are adopted in the same period. The guidance requires application using a retrospective transition method. The Company does not expect that this ASU will have a significant impact on its consolidated financial statements.

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, 2015 for a description of the redemption values related to the redeemable noncontrolling interests. In accordance with the Financial Accounting Standards Board (“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 Company presents its EPS based on the treasury stock method. The Company reverted to the treasury stock presentation from the two-class presentation due to the immaterial number of participating shares outstanding as of March 31, 2016. If the EPS presentation had been based on the two-class method, the following adjustments would have been made to the presentation of EPS for the three and nine months ended September 30, 2016 . Net income attributable to common shareholders would have been reduced by an additional $4 thousand , for the nine months ended September 30, 2016 , with no change for the three month period then ended.

[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, 2015 for a description of the redemption values related to the redeemable noncontrolling interests. In accordance with the Financial Accounting Standards Board (“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 Company presents its EPS based on the treasury stock method. The Company reverted to the treasury stock presentation from the two-class presentation due to the immaterial number of participating shares outstanding as of March 31, 2016. If the EPS presentation had been based on the two-class method, the following adjustments would have been made to the presentation of EPS for the three and nine months ended September 30, 2016. Net income attributable to common shareholders would have been reduced by an additional $4 thousand, for the nine months ended September 30, 2016, with no change for the three month period then ended. The allocation of net income to participating securities would have been $1 thousand and $7 thousand, for the three and nine months ended September 30, 2016, respectively, reducing net income attributable to common shareholders by a total of $1 thousand and $11 thousand, for the three and nine months ended September 30, 2016, respectively. Basic EPS would not change. Weighted average diluted shared outstanding would have been reduced by 3,809 shares and 13,477 shares for the three and nine months ended September 30, 2016, respectively. Diluted EPS would not change.If the EPS presentation had been based on the two-class method, the following adjustments would have been made to the presentation of EPS for the three and nine months ended September 30, 2015. Net income attributable to common shareholders would have been reduced by an additional $5 thousand and $85 thousand, for the three and nine months ended September 30, 2015, respectively, and the allocation of net income to participating securities would have been $8 thousand and $91 thousand, for the three and nine months ended September 30, 2015, respectively, reducing net income attributable to common shareholders by a total of $13 thousand and $176 thousand, for the three and nine months ended September 30, 2015, respectively.
