Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLOCIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES NATURE OF OPERATION TriState Capital Holdings, Inc. ( “we”, “us”, “our” or the “Company”) is a registered bank holding company pursuant to the Bank Holding Company Act of 1956, as amended. The Company has three wholly-owned subsidiaries: TriState Capital Bank (the “Bank”), a Pennsylvania-chartered state bank; Chartwell Investment Partners, LLC (“Chartwell”), a registered investment advisor; and Chartwell TSC Securities Corp. (“CTSC Securities”), a registered broker/dealer. The Bank was established to serve the commercial banking needs of middle-market businesses and private banking needs of high-net-worth individuals. Chartwell provides investment management services primarily to institutional investors, mutual funds and individual investors. CTSC Securities supports marketing efforts for the proprietary investment products provided by Chartwell, including shares of mutual funds advised and/or administered by Chartwell. Regulatory approval was received and the Bank commenced operations on January 22, 2007. The Company and the Bank are subject to regulatory examination by the Federal Deposit Insurance Corporation (“FDIC”), the Pennsylvania Department of Banking and Securities, and the Federal Reserve. Chartwell is a registered investment advisor regulated by the Securities and Exchange Commission (“SEC”). Chartwell was established through the acquisition of substantially all the assets of Chartwell Investment Partners, LP on March 5, 2014. CTSC Securities was capitalized in May 2014, and its broker/dealer registration was approved on March 7, 2017. CTSC Securities is regulated by the SEC and Financial Industry Regulatory Authority (“FINRA”). The Bank conducts business through its main office located in Pittsburgh, Pennsylvania, as well as its four additional representative offices in Cleveland, Ohio; Philadelphia, Pennsylvania; Edison, New Jersey; and New York, New York. Chartwell conducts business through its office located in Berwyn, Pennsylvania and CTSC Securities conducts business through its office located in Pittsburgh, Pennsylvania. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States of America requires management to make estimates and assumptions that affect the reported amounts of certain assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of related revenue and expense during the reporting period. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be different than those anticipated in the estimates, which could materially affect the financial results of our operations and financial condition. The material estimates that are particularly susceptible to significant changes relate to the determination of the allowance for loan losses, valuation of goodwill and other intangible assets and its evaluation for impairment, and deferred income taxes and its related recoverability, which are discussed later in this section. CONSOLIDATION The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, the Bank, Chartwell and CTSC Securities, after elimination of inter-company accounts and transactions. The accounts of the Bank, in turn, include its wholly-owned subsidiary, Meadowood Asset Management, LLC, after elimination of inter-company accounts and transactions. The unaudited consolidated financial statements of the Company presented herein have been prepared pursuant to rules of the Securities and Exchange Commission for quarterly reports on form 10-Q and do not include all of the information and note disclosures required by GAAP for a full year presentation. In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures, considered necessary for the fair presentation of the accompanying consolidated financial statements, have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2016 , included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 14, 2017 . CASH AND CASH EQUIVALENTS For purposes of reporting cash flows, the Company has defined cash and cash equivalents as cash, interest-earning deposits with other institutions, federal funds sold, and short-term investments that have an original maturity of 90 days or less. INVESTMENT SECURITIES The Company’s investments are classified as either: (1) held-to-maturity – debt securities that the Company intends to hold until maturity and are reported at amortized cost; (2) trading securities – debt and certain equity securities bought and held principally for the purpose of selling them in the near term and reported at fair value, with unrealized gains and losses included in earnings; or (3) available-for-sale – debt and certain equity securities not classified as either held-to-maturity or trading securities and reported at fair value, with unrealized gains and losses reported as a component of accumulated other comprehensive income (loss), on an after-tax basis. The cost of securities sold is determined on a specific identification basis. Amortization of premiums and accretion of discounts are recorded as interest income on investments over the estimated life of the security utilizing the level yield method. We evaluate impaired investment securities quarterly to determine if impairments are temporary or other-than-temporary. For impaired debt and equity securities, management first determines whether it intends to sell or if it is more-likely than not that it will be required to sell the impaired securities. This determination considers current and forecasted liquidity requirements, regulatory and capital requirements and securities portfolio management. If the Company intends to sell a security with a fair value below amortized cost or if it is more-likely than not that it will be required to sell such a security before recovery, an other-than-temporary impairment (“OTTI”) charge is recorded through current period earnings for the full decline in fair value below amortized cost. For debt securities that the Company does not intend to sell or it is more likely than not that it will not be required to sell before recovery, an OTTI charge is recorded through current period earnings for the amount of the valuation decline below amortized cost that is attributable to credit losses. The remaining difference between the security’s fair value and amortized cost (that is, the decline in fair value not attributable to credit losses) is recognized in other comprehensive income (loss), in the consolidated statements of comprehensive income and the shareholders’ equity section of the consolidated statements of financial condition, on an after-tax basis. For equity securities an OTTI charge is recorded through current period earnings for the full decline in fair value below cost. FEDERAL HOME LOAN BANK STOCK The Company is a member of the Federal Home Loan Bank of Pittsburgh (“FHLB”). Member institutions are required to invest in FHLB stock. The stock is carried at cost, which approximates its liquidation value, and it is evaluated for impairment based on the ultimate recoverability of the par value. The following matters are considered by management when evaluating the FHLB stock for impairment: the ability of the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; the impact of legislative and regulatory changes on the institution and its customer base; and the Company’s intent and ability to hold its FHLB stock for the foreseeable future. Management believes the Company’s holdings in the FHLB stock were recoverable at par value, as of September 30, 2017 and December 31, 2016 . Cash and stock dividends are reported as interest income on investments, in the consolidated statements of income. LOANS Loans and leases held-for investment are stated at unpaid principal balances, net of deferred loan fees and costs. Loans held-for-sale are stated at the lower of cost or fair value. Interest income on loans is accrued at the contractual rate on the principal amount outstanding and includes the amortization of deferred loan fees and costs. Deferred loan fees and costs are amortized to interest income over the estimated life of the loan, taking into consideration scheduled payments and prepayments. The Company considers a loan to be a Troubled Debt Restructuring (“TDR”) when there is a concession made to a financially troubled borrower without adequate consideration provided to the Company. Once a loan is deemed to be a TDR, the Company considers whether the loan should be placed on non-accrual status. In assessing accrual status, the Company considers the likelihood that repayment and performance according to the original contractual terms will be achieved, as well as the borrower’s historical payment performance. A loan is designated and reported as a TDR until such loan is either paid-off or sold, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is fully expected that the remaining principal and interest will be collected according to the restructured agreement. The recognition of interest income on a loan is discontinued when, in management’s opinion, it is probable the borrower is unable to meet payments as they become due or when the loan becomes 90 days past due, whichever occurs first. All accrued and unpaid interest on such loans is reversed. Such interest ultimately collected is applied to reduce principal if there is doubt about the collectability of principal. If a borrower brings a loan current for which accrued interest has been reversed, then the recognition of interest income on the loan is resumed, once the loan has been current for a period of six consecutive months or greater. The Company is a party to financial instruments with off-balance sheet risk (commitments to extend credit) in the normal course of business to meet the financing needs of its customers. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the commitment. Commitments generally have fixed expiration dates or other termination clauses (i.e. demand loans) and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the unfunded commitment amount does not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis using the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The amount of collateral obtained, if deemed necessary by the Company upon extension of a commitment, is based on management’s credit evaluation of the borrower. OTHER REAL ESTATE OWNED Real estate owned, other than bank premises, is recorded at fair value less estimated selling costs. Fair value is determined based on an independent appraisal. Expenses related to holding the property are charged against earnings when incurred. Depreciation is not recorded on other real estate owned (“OREO”) properties. ALLOWANCE FOR LOAN LOSSES The allowance for loan losses is established through provisions for loan losses that are recorded in the consolidated statements of income. Loans are charged off against the allowance for loan losses when management believes that the principal is uncollectible. If, at a later time, amounts are recovered with respect to loans previously charged off, the recovered amount is credited to the allowance for loan losses. In management’s judgment the allowance was appropriate to cover probable losses inherent in the loan portfolio as of September 30, 2017 and December 31, 2016 . Management’s judgment takes into consideration general economic conditions, diversification and seasoning of the loan portfolio, historic loss experience, identified credit problems, delinquency levels and adequacy of collateral. Although management believes it has used the best information available to it in making such determinations, and that the present allowance for loan losses is adequate, future adjustments to the allowance may be necessary, and net income may be adversely affected if circumstances differ substantially from the assumptions used in determining the level of the allowance. In addition, as an integral part of their periodic examination, certain regulatory agencies review the adequacy of the Bank’s allowance for loan losses and may direct the Bank to make additions to the allowance based on their judgments about information available to them at the time of their examination. The two components of the allowance for loan losses represent estimates of general reserves based upon Accounting Standards Codification (“ASC”) Topic 450, Contingencies; and specific reserves based upon ASC Topic 310, Receivables . ASC Topic 450 applies to homogeneous loan pools such as commercial loans, consumer lines of credit, and residential mortgages that are not individually evaluated for impairment. ASC Topic 310 is applied to commercial and consumer loans that are individually evaluated for impairment. In management’s opinion a loan is impaired, based upon current information and events, when it is probable that the loan will not be repaid according to its original contractual terms, including both principal and interest, or if a loan is designated as a TDR. Management performs individual assessments of impaired loans to determine the existence of loss exposure based upon a discounted cash flows method or where a loan is collateral dependent, based upon the fair value of the collateral less estimated selling costs. In estimating probable loan loss of general reserves management considers numerous factors, including historical charge-offs and subsequent recoveries. Management also considers, but is not limited to, qualitative factors that influence our credit quality, such as delinquency and non-performing loan trends, changes in loan underwriting guidelines and credit policies, the results of internal loan reviews, etc. Finally, management considers the impact of changes in current local and regional economic conditions in the markets that we serve. Assessment of relevant economic factors indicates that some of the Company’s primary markets may historically tend to lag the national economy, with local economies in our primary market areas also improving or weakening, as the case may be, but at a more measured rate than the national trends. Management bases the computation of the allowance for loan losses of general reserves on two factors: the primary factor and the secondary factor. The primary factor is based on the inherent risk identified by management within each of the Company’s three loan portfolios based on the historical loss experience of each loan portfolio and the loss emergence period. Management has developed a methodology that is applied to each of the three primary loan portfolios: private banking, commercial and industrial, and commercial real estate. As the loan loss history, mix and risk ratings of each loan portfolio change, the primary factor adjusts accordingly. The allowance for loan losses related to the primary factor is based on our estimates as to probable losses for each loan portfolio. The secondary factor is intended to capture risks related to events and circumstances that management believes have an impact on the performance of the loan portfolio. Although this factor is more subjective in nature, the methodology focuses on internal and external trends in pre-specified categories (risk factors) and applies a quantitative percentage that drives the secondary factor. There are nine risk factors and each risk factor is assigned a reserve level based on management’s judgment as to the probable impact of each risk factor on each loan portfolio and is monitored on a quarterly basis. As the trend in any risk factor changes, a corresponding change occurs in the reserve associated with each respective risk factor, such that the secondary factor remains current to changes in each loan portfolio. The Company also maintains a reserve for losses on unfunded commitments. This reserve is reflected as a component of other liabilities and, in management’s judgment, is sufficient to cover probable losses inherent in the commitments. Management tracks the level and trends in unused commitments and takes into consideration the same factors as those considered for purposes of the allowance for loan losses on outstanding loans. INVESTMENT MANAGEMENT FEES The Company recognizes investment management fee revenue when the advisory services are performed. Fees are based on assets under management and are calculated pursuant to individual client contracts. Investment management fees are generally paid on a quarterly basis. Investment management fees receivable represent amounts due for contractual investment management services provided to the Company’s clients, primarily institutional investors, mutual funds and individual investors. Management performs credit evaluations of its customers’ financial condition when it is deemed to be necessary, and does not require collateral. The Company provides an allowance for uncollectible accounts based on specifically identified receivables. Bad debt expense is recorded to other non-interest expense on the consolidated statements of income and the allowance for uncollectible accounts is recorded to investment management fees receivable, net on the consolidated statements of financial position. Investment management fees receivable are considered delinquent when payment is not received within contractual terms and are charged off against the allowance for uncollectible accounts when management determines that recovery is unlikely and the Company ceases its collection efforts. There was $322,000 of bad debt expense associated with a single relationship recorded for the nine months ended September 30, 2017 , and no allowance for uncollectible accounts as of September 30, 2017 . There was no bad debt expense recorded for the nine months ended September 30, 2016 , and there was no allowance for uncollectible accounts as of December 31, 2016 . BUSINESS COMBINATIONS The Company accounts for business combinations using the acquisition method of accounting. Under this method of accounting, the acquired company’s net assets are recorded at fair value as of the date of acquisition, and the results of operations of the acquired company are combined with our results from that date forward. Acquisition costs are expensed when incurred. The difference between the purchase price and the fair value of the net assets acquired (including identified intangibles) is recorded as goodwill. The change in the initial estimate of any contingent earn out amounts is reflected in the consolidated statements of income. GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill is not amortized and is subject to at least annual assessments for impairment by applying a fair value based test. The Company reviews goodwill annually and again at any quarter-end if a material event occurs during the quarter that may affect goodwill. If goodwill testing is required, an assessment of qualitative factors can be completed before performing the two step goodwill impairment test. If an assessment of qualitative factors determines it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, then the two step goodwill impairment test is not required. Goodwill is evaluated for potential impairment by determining if the fair value has fallen below carrying value. Other intangible assets represent purchased assets that may lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. The Company has determined that certain of its acquired mutual fund client relationships meet the criteria to be considered indefinite-lived assets because the Company expects both the renewal of these contracts and the cash flows generated by these assets to continue indefinitely. Accordingly, the Company does not amortize these intangible assets, but instead reviews these assets annually or more frequently whenever events or circumstances occur indicating that the recorded indefinite-lived assets may be impaired. Each reporting period, the Company assesses whether events or circumstances have occurred which indicate that the indefinite life criteria are no longer met. If the indefinite life criteria are no longer met, the Company would assess whether the carrying value of these assets exceeds its fair value, an impairment loss would be recorded in an amount equal to any such excess and these assets would be reclassified to finite-lived. Other intangible assets that the Company has determined to have finite lives, such as trade name, client lists and non-compete agreements, are amortized over their estimated useful lives. These finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives, which range from four to twenty-five years. Finite-lived intangibles are evaluated for impairment on an annual basis or more frequently whenever events or circumstances occur indicating that the carrying amount may not be recoverable. OFFICE PROPERTIES AND EQUIPMENT Office properties and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives of the related assets, except for leasehold improvements, which are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Estimated useful lives are dependent upon the nature and condition of the asset and range from three to ten years. Repairs and maintenance are charged to expense as incurred, while improvements that extend the useful life are capitalized and depreciated to non-interest expense over the estimated remaining life of the asset. When the Bank receives an allowance for improvements to be made to one of its leased offices, we record the allowance as a deferred liability and recognize it as a reduction to rent expense over the life of the related lease. BANK OWNED LIFE INSURANCE Bank owned life insurance (“BOLI”) policies on certain officers and employees are recorded at net cash surrender value on the consolidated statements of financial condition. Upon termination of the BOLI policy the Company receives the cash surrender value. BOLI benefits are payable to the Company upon death of the insured. Changes in net cash surrender value are recognized as non-interest income in the consolidated statements of income. DEPOSITS Deposits are stated at principal outstanding. Interest on deposits is accrued and charged to interest expense daily and is paid or credited in accordance with the terms of the respective accounts. BORROWINGS The Company records FHLB advances, line of credit borrowings and subordinated notes payable at their principal amount net of debt issuance costs. Interest expense is recognized based on the coupon rate of the obligations. Costs associated with the acquisition of subordinated notes payable are amortized to interest expense over the expected term of the borrowing. EARNINGS PER COMMON SHARE Basic earnings per common share (“EPS”) is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding for the period, excluding non-vested restricted stock. Diluted EPS reflects the potential dilution upon the exercise of stock options and the vesting of restricted stock awards granted utilizing the treasury stock method. INCOME TAXES The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the tax effects of differences between the financial statement and tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities with regard to a change in tax rates is recognized in income in the period that includes the enactment date. Management assesses all available evidence to determine the amount of deferred tax assets that are more-likely-than-not to be realized. The available evidence used in connection with the assessments includes taxable income in prior periods, projected taxable income, potential tax planning strategies and projected reversals of deferred tax items. These assessments involve a degree of subjectivity and may undergo significant change. Changes to the evidence used in the assessments could have a material adverse effect on the Company’s results of operations in the period in which they occur. The Company considers uncertain tax positions that it has taken or expects to take on a tax return. Any interest and penalties related to unrecognized tax benefits would be recognized in income tax expense in the consolidated statements of income. DERIVATIVES AND HEDGING ACTIVITIES The Company evaluates all derivatives at inception as to whether or not they are hedging or non-hedging activities. All derivatives are recognized as either assets or liabilities on the consolidated statements of financial condition and measured at fair value. For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. Any hedge ineffectiveness would be recognized in the income statement line item pertaining to the hedged item. For derivatives designated as cash flow hedges, changes in fair value of the effective portion of the cash flow hedges are reported in accumulated other comprehensive income (loss). When the cash flows associated with the hedged item are realized, the gain or loss included in accumulated other comprehensive income (loss) is recognized in the consolidated statements of income. The Company also has interest derivative positions that are not designated as hedging instruments. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings. FAIR VALUE MEASUREMENT Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in a principal or most advantageous market for the asset or liability in an orderly transaction between market participants as of the measurement date, using assumptions market participants would use when pricing an asset or liability. An orderly transaction assumes exposure to the market for a customary period for marketing activities prior to the measurement date and not a forced liquidation or distressed sale. Fair value measurement and disclosure guidance provides a three-level hierarchy that prioritizes the inputs of valuation techniques used to measure fair value into three broad categories: • Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 – Observable inputs such as quoted prices for similar assets and liabilities in active markets, quoted prices for similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies, and similar techniques that use significant unobservable inputs. Fair value may be recorded for certain assets and liabilities every reporting period on a recurring basis or under certain circumstances, on a non-recurring basis. STOCK-BASED COMPENSATION The Company accounts for its stock-based compensation awards based on estimated fair values of the share-based awards made to employees and directors. Compensation cost for all share-based payments is based on the estimated grant-date fair value. The value of the portion of the award that is ultimately expected to vest is included in stock-based compensation expense in the consolidated statements of income and recorded as a component of additional paid-in capital, for equity-based awards. Compensation expense for all awards is recognized on a straight-line basis over the requisite service period for the entire grant. ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) Unrealized holding gains and the non-credit component of unrealized losses on the Company’s investment securities available-for-sale are included in accumulated other comprehensive income (loss), net of applicable income taxes. Also included in accumulated other comprehensive income (loss) is the remaining unamortized balance of the unrealized holding gains (non-credit losses), net of applicable income taxes, that existed on the transfer date for investment securities reclassified into the held-to-maturity category from the available-for-sale category. Unrealized holding gains (losses) on the effective portion of the Company’s cash flow hedge derivatives are included in accumulated other comprehensive income (loss), net of applicable income taxes, which will be reclassified to interest expense as interest payments are made on the Company’s debt. TREASURY STOCK The repurchase of the Company’s common stock is recorded at cost. At the time of reissuance, the treasury stock account is reduced using the average cost method. Gains and losses on the reissuance of common stock are recorded in additional paid-in capital, to the extent additional paid-in capital from any previous net gains on treasury share transactions exists. Any net deficiency is charged to retained earnings. RECENT ACCOUNTING DEVELOPMENTS In August 2017, the FASB issued Accounting Standard Update (“ASU”) 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities,” which changes the recognition and presentation requirements of hedge accounting, including: eliminating the requirement to separately measure and report hedge ineffectiveness; and presenting all items that affect earnings in the same income statement line item as the hedged item. The standard also provides new alternatives for: applying hedge accounting to additional hedging strategies; measuring the hedged item in fair value hedges of interest rate risk; reducing the cost and complexity of applying hedge accounting by easing the requirements for effectiveness testing, hedge documentation and application of the critical terms match method; and reducing the risk of material error correction if a company applies the shortcut method inappropriately. This standard is effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2018 . The Company is currently evaluating the impact this standard will have on our results of operations and financial position. In May 2017, the FASB issued ASU 2017-09, “Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting,” which clarifies what constitutes a modification of a share-based payment award. This standard is effective for all entities for annual and interim periods in fiscal years beginning after December 15, 2017 . The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. 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,” which shortens the premium amortization period for purchased non-contingently callable debt securities. Shortening the amortization period is generally expected to more closely align the interes

The $39.8 million amortized cost of debt securities held-to-maturity with a contractual maturity due from five to ten years as of September 30, 2017 , included $17.3 million that have call provisions in one to five years that would either mature, if called, or become floating-rate securities after the call date. Prepayments may shorten the contractual lives of the collateralized mortgage obligations, mortgage-backed securities and collateralized loan obligations. Proceeds from the sale of investment securities available-for-sale during the three months ended September 30, 2017 and 2016 , were $0 and $1.7 million , respectively. During the three months ended September 30, 2016 , net gains of $14,000 on sales were comprised of gross gains of $14,000 and gross losses of $0 . Proceeds from the sale of investment securities available-for-sale during the nine months ended September 30, 2017 and 2016 , were $0 and $4.7 million , respectively. Proceeds from the call and prepayments of investment securities available-for-sale during the nine months ended September 30, 2017 and 2016 , were $21.7 million and $0 , respectively. During the nine months ended September 30, 2017 , net gains of $239,000 on calls were comprised of gross gains of $241,000 and gross losses of $2,000 , which were realized and reclassified out of accumulated other comprehensive income (loss). During the nine months ended September 30, 2016 , net gains of $31,000 on sales were comprised of gross gains of $34,000 and gross losses of $3,000 . During the nine months ended September 30, 2017 and 2016 , there were proceeds from the call of investment securities held-to-maturity of $3.0 million and $2.5 million , respectively, which had gross gains of $15,000 and $46,000 , respectively, that were realized on these calls and reclassified out of accumulated other comprehensive income (loss). Investment securities available-for-sale of $4.2 million , as of September 30, 2017 , were held in safekeeping at the FHLB and were included in the calculation of borrowing capacity. The following tables show the fair value and gross unrealized losses on temporarily impaired investment securities available-for-sale and held-to-maturity, by investment category and length of time that the individual securities have been in a continuous unrealized loss position as of September 30, 2017 and December 31, 2016 , respectively: September 30, 2017 Less than 12 Months 12 Months or More Total (Dollars in thousands) Fair value Unrealized losses Fair value Unrealized losses Fair value Unrealized losses Investment securities available-for-sale: Corporate bonds $ 8,950 $ 60 $ — $ — $ 8,950 $ 60 Non-agency collateralized loan obligations — — 894 9 894 9 Agency collateralized mortgage obligations 1,641 1 33,642 93 35,283 94 Agency mortgage-backed securities 9,866 117 1,092 8 10,958 125 Equity securities — — 8,647 204 8,647 204 Total investment securities available-for-sale 20,457 178 44,275 314 64,732 492 Investment securities held-to-maturity: Total investment securities held-to-maturity — — — — — — Total temporarily impaired securities (1) $ 20,457 $ 178 $ 44,275 $ 314 $ 64,732 $ 492 (1) The number of investment positions with unrealized losses totaled 20 for available-for-sale securities and 0 for held-to-maturity securities.

The change in the fair values of our municipal bonds, agency debentures, agency collateralized mortgage obligation and agency mortgage-backed securities are primarily the result of interest rate fluctuations. To assess for credit impairment, management evaluates the underlying issuer’s financial performance and the related credit rating information through a review of publicly available financial statements and other publicly available information. This most recent review did not identify any issues related to the ultimate repayment of principal and interest on these securities. In addition, the Company has the ability and intent to hold debt securities in an unrealized loss position until recovery of their amortized cost. Based on this, the Company considers all of the unrealized losses to be temporary impairment losses. There were no investment securities classified as trading securities outstanding as of September 30, 2017 and December 31, 2016 . There was no activity in investment securities classified as trading during the nine months ended September 30, 2017 and 2016 . There was $10.8 million and $9.6 million in FHLB stock outstanding as of September 30, 2017 and December 31, 2016 , respectively. There were $1.2 million of net purchases in FHLB stock during the nine months ended September 30, 2017 , and $570,000 of net redemptions during the nine months ended September 30, 2016 .

Loans

Loans	9 Months Ended

Receivables [Abstract]
LOANS	LOANS The Company generates loans through the private banking and middle-market banking channels. These channels provide risk diversification and offer significant growth opportunities. The private banking channel primarily includes loans made to high-net-worth individuals, trusts and businesses that are typically secured by cash and marketable securities. The middle-market banking channel consists of our commercial and industrial (“C&I”) and commercial real estate (“CRE”) loan portfolios that serve middle-market businesses and real estate developers in our primary markets. Loans held-for-investment were comprised of the following: September 30, 2017 (Dollars in thousands) Private Commercial Commercial Total Loans held-for-investment, before deferred fees $ 2,052,037 $ 647,910 $ 1,229,548 $ 3,929,495 Deferred loan costs (fees) 3,771 810 (3,406 ) 1,175 Loans held-for-investment, net of deferred fees 2,055,808 648,720 1,226,142 3,930,670 Allowance for loan losses (1,491 ) (9,593 ) (4,895 ) (15,979 ) Loans held-for-investment, net $ 2,054,317 $ 639,127 $ 1,221,247 $ 3,914,691 December 31, 2016 (Dollars in thousands) Private Commercial Commercial Total Loans held-for-investment, before deferred fees $ 1,732,578 $ 587,791 $ 1,080,637 $ 3,401,006 Deferred loan costs (fees) 3,350 (368 ) (2,934 ) 48 Loans held-for-investment, net of deferred fees 1,735,928 587,423 1,077,703 3,401,054 Allowance for loan losses (1,424 ) (12,326 ) (5,012 ) (18,762 ) Loans held-for-investment, net $ 1,734,504 $ 575,097 $ 1,072,691 $ 3,382,292 The Company’s customers have unused loan commitments based on the availability of eligible collateral or other terms and conditions under the loan agreement . Often these commitments are not fully utilized and therefore the total amount does not necessarily represent future cash requirements. The amount of unfunded commitments, including standby letters of credit, as of September 30, 2017 and December 31, 2016 , was $2.19 billion and $1.75 billion , respectively. The interest rate for each commitment is based on the prevailing market conditions at the time of funding. The reserve for losses on unfunded commitments was $588,000 and $650,000 as of September 30, 2017 and December 31, 2016 , respectively, which includes reserves for probable losses on unfunded loan commitments, including standby letters of credit and also risk participations. The total unfunded commitments above included loans in the process of origination totaling approximately $45.8 million and $59.8 million as of September 30, 2017 and December 31, 2016 , respectively, which extend over varying periods of time. The Company issues standby letters of credit in the normal course of business. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party. The Company would be required to perform under the standby letters of credit when drawn upon by the guaranteed party in the case of non-performance by the Company’s customer. Collateral may be obtained based on management’s credit assessment of the customer. The amount of unfunded commitments related to standby letters of credit as of September 30, 2017 and December 31, 2016 , included in the total unfunded commitments above, was $73.5 million and $77.4 million , respectively. Should the Company be obligated to perform under the standby letters of credit the Company will seek repayment from the customer for amounts paid. During the nine months ended September 30, 2017 , there were seven draws on standby letters of credit totaling $191,000 , which were converted to loans and subsequently repaid by the borrowers. During the nine months ended September 30, 2016 , there was one draw on a standby letter of credit for $100,000 , which was immediately repaid by the borrower. Most of these commitments are expected to expire without being drawn upon and the total amount does not necessarily represent future cash requirements. The potential liability for losses on standby letters of credit was included in the reserve for losses on unfunded commitments. The Company has entered into risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which we are a participant.

Allowance for Loan Losses [Abstract]
ALLOWANCE FOR LOAN LOSSES	ALLOWANCE FOR LOAN LOSSES Our allowance for loan losses represents our estimate of probable loan losses inherent in the loan portfolio at a specific point in time. This estimate includes losses associated with specifically identified loans, as well as estimated probable credit losses inherent in the remainder of the loan portfolio. Additions are made to the allowance through both periodic provisions recorded in the consolidated statements of income and recoveries of losses previously incurred. Reductions to the allowance occur as loans are charged off or when the credit history of any of the three loan portfolios improves . Management evaluates the adequacy of the allowance quarterly, and in doing so relies on various factors including, but not limited to, assessment of historical loss experience, delinquency and non-accrual trends, portfolio growth, underlying collateral coverage and current economic conditions. This evaluation is subjective and requires material estimates that may change over time. In addition, management evaluates the overall methodology for the allowance for loan losses on an annual basis. The calculation of the allowance for loan losses takes into consideration the inherent risk identified within each of the Company’s three primary loan portfolios: private banking, commercial and industrial, and commercial real estate. In addition, management takes into account the historical loss experience of each loan portfolio, to ensure that the allowance for loan losses is sufficient to cover probable losses inherent in such loan portfolios. Refer to Note 1, Summary of Significant Accounting Policies , for more details on the Company’s allowance for loan losses policy. The following discusses key characteristics and risks within each primary loan portfolio: Private Banking Loans Our private banking lending activities are conducted on a national basis. This loan portfolio primarily includes loans made to high-net-worth individuals, trusts and businesses that are typically secured by cash and marketable securities. This portfolio also has some loans that are secured by residential real estate or other financial assets, lines of credit and unsecured loans. The primary sources of repayment for these loans are the income and/or assets of the borrower. The underlying collateral is the most important indicator of risk for this loan portfolio. The overall lower risk profile of this portfolio is driven by loans secured by cash and marketable securities, which were 93.9% and 91.3% of total private banking loans as of September 30, 2017 and December 31, 2016 , respectively. Middle-Market Banking: Commercial and Industrial Loans This loan portfolio primarily includes loans made to service companies or manufacturers generally for the purposes of financing production, operating capacity, accounts receivable, inventory, equipment, acquisitions and recapitalizations. Cash flow from the borrower’s operations is the primary source of repayment for these loans. The borrower’s industry and local and regional economic conditions are important indicators of risk for this loan portfolio. Collateral for these types of loans at times does not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt. C&I loans collateralized by cash and marketable securities are treated the same as private banking loans for purposes of the allowance for loan loss calculation. In addition, shared national credit loans that also involve a private equity sponsor are combined as a homogeneous group and evaluated separately based on the historical loss trend of such loans. Middle-Market Banking: Commercial Real Estate Loans This loan portfolio includes loans secured by commercial purpose real estate, including both owner occupied properties and investment properties for various purposes including office, industrial, multifamily, retail, hospitality, healthcare and self-storage. The primary source of repayment for commercial real estate loans secured by owner occupied properties is cash flow from the borrower’s operations. Individual project cash flows, global cash flows and liquidity from the developer, or the sale of the property are the primary sources of repayment for commercial real estate loans secured by investment properties. Also included are commercial construction loans to finance the construction or renovation of structures as well as to finance the acquisition and development of raw land for various purposes. The increased level of risk for these loans is generally confined to the construction period. If there are problems, the project may not be completed, and as such, may not provide sufficient cash flow on its own to service the debt or have sufficient value in a liquidation to cover the outstanding principal. The underlying purpose/collateral of the loans is an important indicator of risk for this loan portfolio. Additional risks exist and are dependent on several factors such as the condition of the local/regional economy, whether or not the project is owner occupied, the type of project, and the experience and resources of the developer. On a monthly basis, management monitors various credit quality indicators for the loan portfolio, including delinquency, non-performing status, changes in risk ratings, changes in the underlying performance of the borrowers and other relevant factors. On a daily basis, the Company monitors the collateral of loans secured by cash and marketable securities within the private banking portfolio, which further reduces the risk profile of that portfolio. Refer to Note 1, Summary of Significant Accounting Policies , for the Company’s policy for determining past due status of loans. Loan risk ratings are assigned based upon the creditworthiness of the borrower and the quality of the collateral for loans secured by marketable securities. Loan risk ratings are reviewed on an ongoing basis according to internal policies. Loans within the pass rating are believed to have a lower risk of loss than loans that are risk rated as special mention, substandard and doubtful, which are believed to have an increasing risk of loss. Our internal risk ratings are consistent with regulatory guidance. Management also monitors the loan portfolio through a formal periodic review process. All non-pass rated loans are reviewed monthly and higher risk-rated loans within the pass category are reviewed three times a year. The Company’s risk ratings are consistent with regulatory guidance and are as follows: Pass – The loan is currently performing in accordance with its contractual terms. Special Mention – A special mention loan has potential weaknesses that warrant management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects or in our credit position at some future date. Economic and market conditions, beyond the customer’s control, may in the future necessitate this classification. Substandard – A substandard loan is not adequately protected by the net worth and/or paying capacity of the obligor or by the collateral pledged, if any. Substandard loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. These loans are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful – A doubtful loan has all the weaknesses inherent in a loan categorized as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable.

Loans are considered non-performing when interest and principal were 90 days or more past due or management has determined that it is probable the borrower is unable to meet payments as they become due. The risk of loss is generally highest for non-performing loans. Management determines loans to be impaired when, based upon current information and events, it is probable that the loan will not be repaid according to the original contractual terms of the loan agreement, including both principal and interest, or if a loan is designated as a TDR. Refer to Note 1, Summary of Significant Accounting Policies , for the Company’s policy on evaluating loans for impairment and interest income.

Regulatory Capital

Regulatory Capital Requirements [Abstract]
REGULATORY CAPITAL	REGULATORY CAPITAL The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory – and possibly additional discretionary – actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s and the Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the tables below) of Common Equity Tier 1 (“CET 1”), Tier 1 and Total risk-based capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to average assets (as defined). As of September 30, 2017 and December 31, 2016 , TriState Capital Holdings, Inc. and TriState Capital Bank exceeded all capital adequacy requirements to which they were subjected. Financial depository institutions are categorized as well capitalized if they meet minimum capital ratios as set forth in the tables below. The Bank exceeded the capital ratios necessary to be well capitalized under the regulatory framework for prompt corrective action. There have been no conditions or events since the filing of the most recent Call Report that management believes have changed the Bank’s capital, as presented in the tables below. Basel III, which began phasing in on January 1, 2015, has replaced the existing regulatory capital rules for the Company and the Bank. The Basel III final rules required new minimum capital ratio standards, established a new common equity tier 1 to total risk-weighted assets ratio, subjected banking organizations to certain limitations on capital distributions and discretionary bonus payments, and established a new standardized approach for risk weightings. The final rules subject a banking organization to certain limitations on capital distributions and discretionary bonus payments to executive officers if the organization does not maintain a capital conservation buffer of risk-based capital ratios in an amount greater than 2.5% of its total risk-weighted assets. The implementation of the capital conservation buffer began on January 1, 2016, at 0.625% and will be phased in over a four -year period (increasing by that amount ratably on each subsequent January 1, until it reaches 2.5% on January 1, 2019).

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING ACTIVITY	DERIVATIVES AND HEDGING ACTIVITY RISK MANAGEMENT OBJECTIVE OF USING DERIVATIVES 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 debt funding and through 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 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 related to certain of the Company’s fixed-rate loan assets and differences in the amount, timing, and duration of the Company's known or expected cash payments related to certain of the Company's FHLB borrowings. The Company also has derivatives that are a result of a service the Company provides to certain qualifying customers while at the same time the Company enters into an offsetting derivative transaction in order to eliminate its interest rate risk exposure resulting from such transactions. FAIR VALUES OF DERIVATIVE INSTRUMENTS ON THE STATEMENTS OF FINANCIAL CONDITION The tables below present the fair value of the Company’s derivative financial instruments as well as their classification on the consolidated statements of financial condition as of September 30, 2017 and December 31, 2016 : Asset Derivatives Liability Derivatives as of September 30, 2017 as of September 30, 2017 (Dollars in thousands) Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives designated as hedging instruments: Interest rate products Other assets $ 1,448 Other liabilities $ 24 Derivatives not designated as hedging instruments: Interest rate products Other assets 11,870 Other liabilities 12,038 Total Other assets $ 13,318 Other liabilities $ 12,062 Asset Derivatives Liability Derivatives as of December 31, 2016 as of December 31, 2016 (Dollars in thousands) Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives designated as hedging instruments: Interest rate products Other assets $ 1,793 Other liabilities $ 80 Derivatives not designated as hedging instruments: Interest rate products Other assets 10,324 Other liabilities 10,529 Total Other assets $ 12,117 Other liabilities $ 10,609 The following tables show the impact legally enforceable master netting agreements had on the Company’s derivative financial instruments as of September 30, 2017 : Offsetting of Derivative Assets September 30, 2017 Gross Amounts of Recognized Assets Gross Amounts Offset in the Statement of Financial Position Net Amounts of Assets Gross Amounts Not Offset in the Statement of Financial Position Net Amount (Dollars in thousands) Financial Instruments Cash Collateral Received Derivatives $ 13,318 $ — $ 13,318 $ (5,070 ) $ — $ 8,248 Offsetting of Derivative Liabilities September 30, 2017 Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Statement of Financial Position Net Amounts of Liabilities Gross Amounts Not Offset in the Statement of Financial Position Net Amount (Dollars in thousands) Financial Instruments Cash Collateral Posted Derivatives $ 12,062 $ — $ 12,062 $ (5,070 ) $ (2,871 ) $ 4,121 FAIR VALUE HEDGES OF INTEREST RATE RISK The Company is exposed to changes in the fair value of certain of its fixed-rate obligations due to changes in benchmark interest rates, which relate predominantly to LIBOR. Interest rate swaps designated as fair value hedges involve the receipt of variable-rate payments from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. As of September 30, 2017 , the Company had four interest rate swaps, with an aggregate notional amount of $2.5 million that were designated as fair value hedges of interest rate risk associated with the Company’s fixed-rate loan assets. The notional amounts for the derivatives express the face amount of the positions and credit risk was considered insignificant for nine months ended September 30, 2017 and 2016 . There were no counterparty default losses on derivatives for the nine months ended September 30, 2017 and 2016 . For the four derivatives that were designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in earnings by applying the “fair value long haul” method. The Company includes the gain or loss on the hedged items in the same line item as the offsetting loss or gain on the related derivatives. The table below presents the effect of the Company’s fair value hedge instruments in the consolidated statements of income: Three Months Ended September 30, Nine Months Ended September 30, (Dollars in thousands) 2017 2016 2017 2016 Derivatives designated as hedging instruments: Location of Gain (Loss) Recognized in Income on Derivative Amount of Gain (Loss) Recognized in Income on Derivative Amount of Gain (Loss) Recognized in Income on Derivative Interest rate products Interest income $ (15 ) $ (24 ) $ (46 ) $ (71 ) Interest rate products Non-interest income 1 — 4 2 Total $ (14 ) $ (24 ) $ (42 ) $ (69 ) CASH FLOW HEDGES OF INTEREST RATE RISK The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. In June 2016, the Company entered into derivative contracts to hedge the variable cash flows associated with certain FHLB borrowings. These interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. The Company’s cash flow hedge derivatives did not have any hedge ineffectiveness recognized in earnings during the nine months ended September 30, 2017 . As of September 30, 2017 , the Company had two outstanding interest rate derivatives with an aggregate notional amount of $100.0 million that was designated as a cash flow hedge of interest rate risk. During the three and nine months ended September 30, 2017 , an unrealized net gain of $86,000 and net loss of $70,000 , respectively, was recognized in accumulated other comprehensive income (loss) on the effective portion of the derivative. During the three and nine months ended September 30, 2016 , an unrealized net gain of $626,000 and $538,000 , respectively, was recognized in accumulated other comprehensive income (loss) on the effective portion of the derivative. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s debt. During the next twelve months, the Company estimates $719,000 to be reclassified to earnings as a decrease to interest expense. The Company is hedging its exposure to the variability in future cash flows for forecasted transactions over a remaining period of 21 months . The table below presents the effect of the Company’s cash flow hedge instruments in the consolidated statements of income: Three Months Ended September 30, Nine Months Ended September 30, (Dollars in thousands) 2017 2016 2017 2016 Derivatives designated as hedging instruments: Location of Gain (Loss) Recognized in Income on Derivative Amount of Gain (Loss) Recognized in Income on Derivative Amount of Gain (Loss) Recognized in Income on Derivative Interest rate products Interest expense $ 120 $ (46 ) $ 243 $ (46 ) Total $ 120 $ (46 ) $ 243 $ (46 ) NON-DESIGNATED HEDGES The Company does not use derivatives for trading or speculative purposes. Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. The Company executes interest rate derivatives with its commercial banking customers to facilitate their respective risk management strategies. Those derivatives are simultaneously and economically hedged by offsetting derivatives that the Company executes with a third party, such that the Company eliminates its interest rate exposure resulting from such transactions. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings. As of September 30, 2017 , the Company had 294 derivative transactions with an aggregate notional amount of $1.30 billion related to this program. The table below presents the effect of the Company’s non-designated hedge instruments in the consolidated statements of income: Three Months Ended September 30, Nine Months Ended September 30, (Dollars in thousands) 2017 2016 2017 2016 Derivatives not designated as hedging instruments: Location of Gain (Loss) Recognized in Income on Derivative Amount of Gain (Loss) Recognized in Income on Derivative Amount of Gain (Loss) Recognized in Income on Derivative Interest rate products Non-interest income $ (25 ) $ 62 $ 175 $ (777 ) Total $ (25 ) $ 62 $ 175 $ (777 ) CREDIT-RISK-RELATED CONTINGENT FEATURES The Company has agreements with each of its derivative counterparties that contain a provision where, if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company has agreements with certain of its derivative counterparties that contain a provision where, if either the Company or the counterparty fails to maintain its status as a well/adequately capitalized institution, then the Company or the counterparty could be required to terminate any outstanding derivative positions and settle its obligations under the agreement. As of September 30, 2017 , the termination value of derivatives for which we had master netting arrangements with the counterparty and in a net liability position was $2.7 million , including accrued interest. As of September 30, 2017 , the Company has minimum collateral posting thresholds with certain of its derivative counterparties and has posted collateral of $4.9 million . If the Company had breached any of these provisions as of September 30, 2017 , it could have been required to settle its obligations under the agreements at their termination value.

Fair Value Disclosures [Abstract]
DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS	DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS Fair value estimates of financial instruments are based on the present value of expected future cash flows, quoted market prices of similar financial instruments, if available, and other valuation techniques. These valuations are significantly affected by discount rates, cash flow assumptions and risk assumptions used. Therefore, fair value estimates may not be substantiated by comparison to independent markets and are not intended to reflect the proceeds that may be realized in an immediate settlement of instruments. Accordingly, the aggregate fair value amounts presented below do not represent the underlying value of the Company. FAIR VALUE MEASUREMENTS In accordance with U.S. GAAP the Company must account for certain financial assets and liabilities at fair value on a recurring and non-recurring basis. The Company utilizes a three-level fair value hierarchy of valuation techniques to estimate the fair value of its financial assets and liabilities based on whether the inputs to those valuation techniques are observable or unobservable. The fair value hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within multiple levels of the fair value hierarchy, the lowest level input that has a significant impact on fair value measurement is used. Financial assets and liabilities are categorized based upon the following characteristics or inputs to the valuation techniques: • Level 1 – Financial assets and liabilities for which inputs are observable and are obtained from reliable quoted prices for identical assets or liabilities in actively traded markets. This is the most reliable fair value measurement and includes, for example, active exchange-traded equity securities. • Level 2 – Financial assets and liabilities for which values are based on quoted prices in markets that are not active or for which values are based on similar assets or liabilities that are actively traded. Level 2 also includes pricing models in which the inputs are corroborated by market data, for example, matrix pricing. • Level 3 – Financial assets and liabilities for which values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Level 3 inputs include assumptions of a source independent of the reporting entity or the reporting entity’s own assumptions that are supported by little or no market activity or observable inputs. The Company is responsible for the valuation process and as part of this process may use data from outside sources in establishing fair value. The Company performs due diligence to understand the inputs used or how the data was calculated or derived. The Company corroborates the reasonableness of external inputs in the valuation process. RECURRING FAIR VALUE MEASUREMENTS The following tables represent assets and liabilities measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016 : September 30, 2017 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets / Financial assets: Investment securities available-for-sale: Corporate bonds $ — $ 57,772 $ — $ 57,772 Trust preferred securities — 18,678 — 18,678 Non-agency mortgage-backed securities — 5,587 — 5,587 Non-agency collateralized loan obligations — 894 — 894 Agency collateralized mortgage obligations — 40,028 — 40,028 Agency mortgage-backed securities — 20,204 — 20,204 Equity securities 8,647 — — 8,647 Interest rate swaps — 13,318 — 13,318 Total financial assets 8,647 156,481 — 165,128 Financial liabilities: Interest rate swaps — 12,062 — 12,062 Total financial liabilities $ — $ 12,062 $ — $ 12,062 December 31, 2016 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets / Financial assets: Investment securities available-for-sale: Corporate bonds $ — $ 54,045 $ — $ 54,045 Trust preferred securities — 17,798 — 17,798 Non-agency mortgage-backed securities — 5,764 — 5,764 Non-agency collateralized loan obligations — 16,180 — 16,180 Agency collateralized mortgage obligations — 43,821 — 43,821 Agency mortgage-backed securities — 24,149 — 24,149 Agency debentures — 4,783 — 4,783 Equity securities 8,352 — — 8,352 Interest rate swaps — 12,117 — 12,117 Total financial assets 8,352 178,657 — 187,009 Financial liabilities: Interest rate swaps — 10,609 — 10,609 Total financial liabilities $ — $ 10,609 $ — $ 10,609 INVESTMENT SECURITIES Generally, debt securities are valued using pricing for similar securities, recently executed transactions, and other pricing models utilizing observable inputs and therefore are classified as Level 2. Equity securities (including mutual funds) are classified as Level 1 because these securities are in actively traded markets. INTEREST RATE SWAPS The fair value of interest rate swaps is estimated using inputs that are observable or that can be corroborated by observable market data and therefore are classified as Level 2. These fair value estimations include primarily market observable inputs such as the forward LIBOR swap curve. NON-RECURRING FAIR VALUE MEASUREMENTS Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment. The following tables represent the balances of assets measured at fair value on a non-recurring basis as of September 30, 2017 and December 31, 2016 : September 30, 2017 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets Loans measured for impairment, net $ — $ — $ 6,781 $ 6,781 Other real estate owned — — 3,581 3,581 Total assets $ — $ — $ 10,362 $ 10,362 December 31, 2016 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets Loans measured for impairment, net $ — $ — $ 10,851 $ 10,851 Other real estate owned — — 4,178 4,178 Total assets $ — $ — $ 15,029 $ 15,029 As of September 30, 2017 and December 31, 2016 , the Company recorded $3.6 million and $6.9 million , respectively, of specific reserves to allowance for loan losses as a result of adjusting the fair value of impaired loans. IMPAIRED LOANS A loan is considered impaired when management determines it is probable that all of the principal and interest due under the original terms of the loan may not be collected or if a loan is designated as a TDR. Impairment is measured based on a discounted cash flows method or the fair value of the underlying collateral less estimated selling costs. Our policy is to obtain appraisals on collateral supporting impaired loans on an annual basis, unless circumstances dictate a shorter time frame. Appraisals are reduced by estimated costs to sell the collateral, and, under certain circumstances, additional factors that may arise and cause us to believe our recoverable value may be less than the independent appraised value. Accordingly, impaired loans are classified as Level 3. The Company measures impairment on all loans as part of the allowance for loan losses. OTHER REAL ESTATE OWNED Real estate owned is comprised of property acquired through foreclosure or voluntarily conveyed by borrowers. These assets are recorded on the date acquired at fair value, less estimated disposition costs, with the fair value being determined by appraisal. Our policy is to obtain appraisals on collateral supporting OREO on an annual basis, unless circumstances dictate a shorter time frame. Appraisals are reduced by estimated costs to sell the collateral, and, under certain circumstances, additional factors that may arise and cause us to believe our recoverable value may be less than the independent appraised value. Accordingly, other real estate owned is classified as Level 3. LEVEL 3 VALUATION The following tables present additional quantitative information about assets measured at fair value on a recurring and non-recurring basis and for which we have utilized Level 3 inputs to determine fair value as of September 30, 2017 and December 31, 2016 : September 30, 2017 (Dollars in thousands) Fair Value Valuation Techniques (1) Significant Unobservable Inputs Weighted Average Loans measured for impairment, net $ 96 Liquidation analysis Discount due to salability conditions — % Loans measured for impairment, net $ 6,685 Discounted cash flow Discount due to restructured nature of operations 6 % Other real estate owned $ 3,581 Appraisal value Discount due to salability conditions 10 % (1) Fair value is generally determined through independent appraisals or liquidation analysis of the underlying collateral, which may include level 3 inputs that are not identifiable, or by using the discounted cash flow method if the loan is not collateral dependent. December 31, 2016 (Dollars in thousands) Fair Value Valuation Techniques (1) Significant Unobservable Inputs Weighted Average Loans measured for impairment, net $ 10,851 Discounted cash flow Discount due to restructured nature of operations 6 % Other real estate owned $ 4,178 Appraisal value Discount due to salability conditions 10 % (1) Fair value is generally determined through independent appraisals of the underlying collateral, which may include level 3 inputs that are not identifiable, or by using the discounted cash flow method if the loan is not collateral dependent.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments as of September 30, 2017 and December 31, 2016 : CASH AND CASH EQUIVALENTS The carrying amount approximates fair value. INVESTMENT SECURITIES The fair values of investment securities available-for-sale, held-to-maturity and trading are based on quoted market prices for the same or similar securities, recently executed transactions and pricing models . FEDERAL HOME LOAN BANK STOCK The carrying value of our FHLB stock, which is a marketable equity investment, approximates fair value. LOANS HELD-FOR-INVESTMENT The fair value of loans held-for-investment is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Fair value as determined here does not represent an exit price. Impaired loans are generally valued at the fair value of the associated collateral. ACCRUED INTEREST RECEIVABLE The carrying amount approximates fair value. INVESTMENT MANAGEMENT FEES RECEIVABLE The carrying amount approximates fair value. BANK OWNED LIFE INSURANCE The fair value of the general account bank owned life insurance is based on the insurance contract net cash surrender value. OTHER REAL ESTATE OWNED Real estate owned is recorded on the date acquired at fair value, less estimated disposition costs, with the fair value being determined by appraisal. DEPOSITS The fair value of demand deposits is the amount payable on demand as of the reporting date, i.e., their carrying amounts. The fair value of fixed maturity deposits is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities. BORROWINGS The fair value of borrowings is calculated by discounting scheduled cash flows through the estimated maturity using period end market rates for borrowings of similar remaining maturities. INTEREST RATE SWAPS The fair value of interest rate swaps are estimated through the assistance of an independent third party and compared to the fair value determined by the swap counterparty to establish reasonableness. OFF-BALANCE SHEET INSTRUMENTS Fair values for the Company’s off-balance sheet instruments, which consist of lending commitments, standby letters of credit and risk participation agreements related to interest rate swap agreements, are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. Management believes that the fair value of these off-balance sheet instruments is not significant.

Summary of Significant Accoun24

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2017
Accounting Policies [Abstract]
Use of estimates	USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States of America requires management to make estimates and assumptions that affect the reported amounts of certain assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of related revenue and expense during the reporting period. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be different than those anticipated in the estimates, which could materially affect the financial results of our operations and financial condition. The material estimates that are particularly susceptible to significant changes relate to the determination of the allowance for loan losses, valuation of goodwill and other intangible assets and its evaluation for impairment, and deferred income taxes and its related recoverability, which are discussed later in this section.
Consolidation	CONSOLIDATION The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, the Bank, Chartwell and CTSC Securities, after elimination of inter-company accounts and transactions. The accounts of the Bank, in turn, include its wholly-owned subsidiary, Meadowood Asset Management, LLC, after elimination of inter-company accounts and transactions. The unaudited consolidated financial statements of the Company presented herein have been prepared pursuant to rules of the Securities and Exchange Commission for quarterly reports on form 10-Q and do not include all of the information and note disclosures required by GAAP for a full year presentation. In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures, considered necessary for the fair presentation of the accompanying consolidated financial statements, have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2016 , included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 14, 2017 .
Cash and cash equivalents	CASH AND CASH EQUIVALENTS For purposes of reporting cash flows, the Company has defined cash and cash equivalents as cash, interest-earning deposits with other institutions, federal funds sold, and short-term investments that have an original maturity of 90 days or less.
Investment securities	INVESTMENT SECURITIES The Company’s investments are classified as either: (1) held-to-maturity – debt securities that the Company intends to hold until maturity and are reported at amortized cost; (2) trading securities – debt and certain equity securities bought and held principally for the purpose of selling them in the near term and reported at fair value, with unrealized gains and losses included in earnings; or (3) available-for-sale – debt and certain equity securities not classified as either held-to-maturity or trading securities and reported at fair value, with unrealized gains and losses reported as a component of accumulated other comprehensive income (loss), on an after-tax basis. The cost of securities sold is determined on a specific identification basis. Amortization of premiums and accretion of discounts are recorded as interest income on investments over the estimated life of the security utilizing the level yield method. We evaluate impaired investment securities quarterly to determine if impairments are temporary or other-than-temporary. For impaired debt and equity securities, management first determines whether it intends to sell or if it is more-likely than not that it will be required to sell the impaired securities. This determination considers current and forecasted liquidity requirements, regulatory and capital requirements and securities portfolio management. If the Company intends to sell a security with a fair value below amortized cost or if it is more-likely than not that it will be required to sell such a security before recovery, an other-than-temporary impairment (“OTTI”) charge is recorded through current period earnings for the full decline in fair value below amortized cost. For debt securities that the Company does not intend to sell or it is more likely than not that it will not be required to sell before recovery, an OTTI charge is recorded through current period earnings for the amount of the valuation decline below amortized cost that is attributable to credit losses. The remaining difference between the security’s fair value and amortized cost (that is, the decline in fair value not attributable to credit losses) is recognized in other comprehensive income (loss), in the consolidated statements of comprehensive income and the shareholders’ equity section of the consolidated statements of financial condition, on an after-tax basis. For equity securities an OTTI charge is recorded through current period earnings for the full decline in fair value below cost.
Federal Home Loan Bank stock	FEDERAL HOME LOAN BANK STOCK The Company is a member of the Federal Home Loan Bank of Pittsburgh (“FHLB”). Member institutions are required to invest in FHLB stock. The stock is carried at cost, which approximates its liquidation value, and it is evaluated for impairment based on the ultimate recoverability of the par value. The following matters are considered by management when evaluating the FHLB stock for impairment: the ability of the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; the impact of legislative and regulatory changes on the institution and its customer base; and the Company’s intent and ability to hold its FHLB stock for the foreseeable future. Management believes the Company’s holdings in the FHLB stock were recoverable at par value, as of September 30, 2017 and December 31, 2016 . Cash and stock dividends are reported as interest income on investments, in the consolidated statements of income.
Loans	LOANS Loans and leases held-for investment are stated at unpaid principal balances, net of deferred loan fees and costs. Loans held-for-sale are stated at the lower of cost or fair value. Interest income on loans is accrued at the contractual rate on the principal amount outstanding and includes the amortization of deferred loan fees and costs. Deferred loan fees and costs are amortized to interest income over the estimated life of the loan, taking into consideration scheduled payments and prepayments. The Company considers a loan to be a Troubled Debt Restructuring (“TDR”) when there is a concession made to a financially troubled borrower without adequate consideration provided to the Company. Once a loan is deemed to be a TDR, the Company considers whether the loan should be placed on non-accrual status. In assessing accrual status, the Company considers the likelihood that repayment and performance according to the original contractual terms will be achieved, as well as the borrower’s historical payment performance. A loan is designated and reported as a TDR until such loan is either paid-off or sold, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is fully expected that the remaining principal and interest will be collected according to the restructured agreement. The recognition of interest income on a loan is discontinued when, in management’s opinion, it is probable the borrower is unable to meet payments as they become due or when the loan becomes 90 days past due, whichever occurs first. All accrued and unpaid interest on such loans is reversed. Such interest ultimately collected is applied to reduce principal if there is doubt about the collectability of principal. If a borrower brings a loan current for which accrued interest has been reversed, then the recognition of interest income on the loan is resumed, once the loan has been current for a period of six consecutive months or greater. The Company is a party to financial instruments with off-balance sheet risk (commitments to extend credit) in the normal course of business to meet the financing needs of its customers. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the commitment. Commitments generally have fixed expiration dates or other termination clauses (i.e. demand loans) and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the unfunded commitment amount does not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis using the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The amount of collateral obtained, if deemed necessary by the Company upon extension of a commitment, is based on management’s credit evaluation of the borrower.
Other real estate owned	OTHER REAL ESTATE OWNED Real estate owned, other than bank premises, is recorded at fair value less estimated selling costs. Fair value is determined based on an independent appraisal. Expenses related to holding the property are charged against earnings when incurred. Depreciation is not recorded on other real estate owned (“OREO”) properties.
Allowance for loan losses	ALLOWANCE FOR LOAN LOSSES The allowance for loan losses is established through provisions for loan losses that are recorded in the consolidated statements of income. Loans are charged off against the allowance for loan losses when management believes that the principal is uncollectible. If, at a later time, amounts are recovered with respect to loans previously charged off, the recovered amount is credited to the allowance for loan losses. In management’s judgment the allowance was appropriate to cover probable losses inherent in the loan portfolio as of September 30, 2017 and December 31, 2016 . Management’s judgment takes into consideration general economic conditions, diversification and seasoning of the loan portfolio, historic loss experience, identified credit problems, delinquency levels and adequacy of collateral. Although management believes it has used the best information available to it in making such determinations, and that the present allowance for loan losses is adequate, future adjustments to the allowance may be necessary, and net income may be adversely affected if circumstances differ substantially from the assumptions used in determining the level of the allowance. In addition, as an integral part of their periodic examination, certain regulatory agencies review the adequacy of the Bank’s allowance for loan losses and may direct the Bank to make additions to the allowance based on their judgments about information available to them at the time of their examination. The two components of the allowance for loan losses represent estimates of general reserves based upon Accounting Standards Codification (“ASC”) Topic 450, Contingencies; and specific reserves based upon ASC Topic 310, Receivables . ASC Topic 450 applies to homogeneous loan pools such as commercial loans, consumer lines of credit, and residential mortgages that are not individually evaluated for impairment. ASC Topic 310 is applied to commercial and consumer loans that are individually evaluated for impairment. In management’s opinion a loan is impaired, based upon current information and events, when it is probable that the loan will not be repaid according to its original contractual terms, including both principal and interest, or if a loan is designated as a TDR. Management performs individual assessments of impaired loans to determine the existence of loss exposure based upon a discounted cash flows method or where a loan is collateral dependent, based upon the fair value of the collateral less estimated selling costs. In estimating probable loan loss of general reserves management considers numerous factors, including historical charge-offs and subsequent recoveries. Management also considers, but is not limited to, qualitative factors that influence our credit quality, such as delinquency and non-performing loan trends, changes in loan underwriting guidelines and credit policies, the results of internal loan reviews, etc. Finally, management considers the impact of changes in current local and regional economic conditions in the markets that we serve. Assessment of relevant economic factors indicates that some of the Company’s primary markets may historically tend to lag the national economy, with local economies in our primary market areas also improving or weakening, as the case may be, but at a more measured rate than the national trends. Management bases the computation of the allowance for loan losses of general reserves on two factors: the primary factor and the secondary factor. The primary factor is based on the inherent risk identified by management within each of the Company’s three loan portfolios based on the historical loss experience of each loan portfolio and the loss emergence period. Management has developed a methodology that is applied to each of the three primary loan portfolios: private banking, commercial and industrial, and commercial real estate. As the loan loss history, mix and risk ratings of each loan portfolio change, the primary factor adjusts accordingly. The allowance for loan losses related to the primary factor is based on our estimates as to probable losses for each loan portfolio. The secondary factor is intended to capture risks related to events and circumstances that management believes have an impact on the performance of the loan portfolio. Although this factor is more subjective in nature, the methodology focuses on internal and external trends in pre-specified categories (risk factors) and applies a quantitative percentage that drives the secondary factor. There are nine risk factors and each risk factor is assigned a reserve level based on management’s judgment as to the probable impact of each risk factor on each loan portfolio and is monitored on a quarterly basis. As the trend in any risk factor changes, a corresponding change occurs in the reserve associated with each respective risk factor, such that the secondary factor remains current to changes in each loan portfolio. The Company also maintains a reserve for losses on unfunded commitments. This reserve is reflected as a component of other liabilities and, in management’s judgment, is sufficient to cover probable losses inherent in the commitments. Management tracks the level and trends in unused commitments and takes into consideration the same factors as those considered for purposes of the allowance for loan losses on outstanding loans.
Investment management fees	INVESTMENT MANAGEMENT FEES The Company recognizes investment management fee revenue when the advisory services are performed. Fees are based on assets under management and are calculated pursuant to individual client contracts. Investment management fees are generally paid on a quarterly basis. Investment management fees receivable represent amounts due for contractual investment management services provided to the Company’s clients, primarily institutional investors, mutual funds and individual investors. Management performs credit evaluations of its customers’ financial condition when it is deemed to be necessary, and does not require collateral. The Company provides an allowance for uncollectible accounts based on specifically identified receivables. Bad debt expense is recorded to other non-interest expense on the consolidated statements of income and the allowance for uncollectible accounts is recorded to investment management fees receivable, net on the consolidated statements of financial position. Investment management fees receivable are considered delinquent when payment is not received within contractual terms and are charged off against the allowance for uncollectible accounts when management determines that recovery is unlikely and the Company ceases its collection efforts. There was $322,000 of bad debt expense associated with a single relationship recorded for the nine months ended September 30, 2017 , and no allowance for uncollectible accounts as of September 30, 2017 . There was no bad debt expense recorded for the nine months ended September 30, 2016 , and there was no allowance for uncollectible accounts as of December 31, 2016 .
Business combinations	BUSINESS COMBINATIONS The Company accounts for business combinations using the acquisition method of accounting. Under this method of accounting, the acquired company’s net assets are recorded at fair value as of the date of acquisition, and the results of operations of the acquired company are combined with our results from that date forward. Acquisition costs are expensed when incurred. The difference between the purchase price and the fair value of the net assets acquired (including identified intangibles) is recorded as goodwill. The change in the initial estimate of any contingent earn out amounts is reflected in the consolidated statements of income.
Goodwill and other intangible assets	GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill is not amortized and is subject to at least annual assessments for impairment by applying a fair value based test. The Company reviews goodwill annually and again at any quarter-end if a material event occurs during the quarter that may affect goodwill. If goodwill testing is required, an assessment of qualitative factors can be completed before performing the two step goodwill impairment test. If an assessment of qualitative factors determines it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, then the two step goodwill impairment test is not required. Goodwill is evaluated for potential impairment by determining if the fair value has fallen below carrying value. Other intangible assets represent purchased assets that may lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. The Company has determined that certain of its acquired mutual fund client relationships meet the criteria to be considered indefinite-lived assets because the Company expects both the renewal of these contracts and the cash flows generated by these assets to continue indefinitely. Accordingly, the Company does not amortize these intangible assets, but instead reviews these assets annually or more frequently whenever events or circumstances occur indicating that the recorded indefinite-lived assets may be impaired. Each reporting period, the Company assesses whether events or circumstances have occurred which indicate that the indefinite life criteria are no longer met. If the indefinite life criteria are no longer met, the Company would assess whether the carrying value of these assets exceeds its fair value, an impairment loss would be recorded in an amount equal to any such excess and these assets would be reclassified to finite-lived. Other intangible assets that the Company has determined to have finite lives, such as trade name, client lists and non-compete agreements, are amortized over their estimated useful lives. These finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives, which range from four to twenty-five years. Finite-lived intangibles are evaluated for impairment on an annual basis or more frequently whenever events or circumstances occur indicating that the carrying amount may not be recoverable.
Office properties and equipment	OFFICE PROPERTIES AND EQUIPMENT Office properties and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives of the related assets, except for leasehold improvements, which are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Estimated useful lives are dependent upon the nature and condition of the asset and range from three to ten years. Repairs and maintenance are charged to expense as incurred, while improvements that extend the useful life are capitalized and depreciated to non-interest expense over the estimated remaining life of the asset. When the Bank receives an allowance for improvements to be made to one of its leased offices, we record the allowance as a deferred liability and recognize it as a reduction to rent expense over the life of the related lease.
Bank owned life insurance	BANK OWNED LIFE INSURANCE Bank owned life insurance (“BOLI”) policies on certain officers and employees are recorded at net cash surrender value on the consolidated statements of financial condition. Upon termination of the BOLI policy the Company receives the cash surrender value. BOLI benefits are payable to the Company upon death of the insured. Changes in net cash surrender value are recognized as non-interest income in the consolidated statements of income.
Deposits	DEPOSITS Deposits are stated at principal outstanding. Interest on deposits is accrued and charged to interest expense daily and is paid or credited in accordance with the terms of the respective accounts.
Borrowings	BORROWINGS The Company records FHLB advances, line of credit borrowings and subordinated notes payable at their principal amount net of debt issuance costs. Interest expense is recognized based on the coupon rate of the obligations. Costs associated with the acquisition of subordinated notes payable are amortized to interest expense over the expected term of the borrowing.
Earnings per common share	EARNINGS PER COMMON SHARE Basic earnings per common share (“EPS”) is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding for the period, excluding non-vested restricted stock. Diluted EPS reflects the potential dilution upon the exercise of stock options and the vesting of restricted stock awards granted utilizing the treasury stock method.
Income taxes	INCOME TAXES The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the tax effects of differences between the financial statement and tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities with regard to a change in tax rates is recognized in income in the period that includes the enactment date. Management assesses all available evidence to determine the amount of deferred tax assets that are more-likely-than-not to be realized. The available evidence used in connection with the assessments includes taxable income in prior periods, projected taxable income, potential tax planning strategies and projected reversals of deferred tax items. These assessments involve a degree of subjectivity and may undergo significant change. Changes to the evidence used in the assessments could have a material adverse effect on the Company’s results of operations in the period in which they occur. The Company considers uncertain tax positions that it has taken or expects to take on a tax return. Any interest and penalties related to unrecognized tax benefits would be recognized in income tax expense in the consolidated statements of income.
Derivatives and hedging activities	DERIVATIVES AND HEDGING ACTIVITIES The Company evaluates all derivatives at inception as to whether or not they are hedging or non-hedging activities. All derivatives are recognized as either assets or liabilities on the consolidated statements of financial condition and measured at fair value. For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. Any hedge ineffectiveness would be recognized in the income statement line item pertaining to the hedged item. For derivatives designated as cash flow hedges, changes in fair value of the effective portion of the cash flow hedges are reported in accumulated other comprehensive income (loss). When the cash flows associated with the hedged item are realized, the gain or loss included in accumulated other comprehensive income (loss) is recognized in the consolidated statements of income. The Company also has interest derivative positions that are not designated as hedging instruments. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings.
Fair value measurement	FAIR VALUE MEASUREMENT Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in a principal or most advantageous market for the asset or liability in an orderly transaction between market participants as of the measurement date, using assumptions market participants would use when pricing an asset or liability. An orderly transaction assumes exposure to the market for a customary period for marketing activities prior to the measurement date and not a forced liquidation or distressed sale. Fair value measurement and disclosure guidance provides a three-level hierarchy that prioritizes the inputs of valuation techniques used to measure fair value into three broad categories: • Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 – Observable inputs such as quoted prices for similar assets and liabilities in active markets, quoted prices for similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies, and similar techniques that use significant unobservable inputs. Fair value may be recorded for certain assets and liabilities every reporting period on a recurring basis or under certain circumstances, on a non-recurring basis.
Stock-based compensation	STOCK-BASED COMPENSATION The Company accounts for its stock-based compensation awards based on estimated fair values of the share-based awards made to employees and directors. Compensation cost for all share-based payments is based on the estimated grant-date fair value. The value of the portion of the award that is ultimately expected to vest is included in stock-based compensation expense in the consolidated statements of income and recorded as a component of additional paid-in capital, for equity-based awards. Compensation expense for all awards is recognized on a straight-line basis over the requisite service period for the entire grant.
Accumulated other comprehensive income (loss)	ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) Unrealized holding gains and the non-credit component of unrealized losses on the Company’s investment securities available-for-sale are included in accumulated other comprehensive income (loss), net of applicable income taxes. Also included in accumulated other comprehensive income (loss) is the remaining unamortized balance of the unrealized holding gains (non-credit losses), net of applicable income taxes, that existed on the transfer date for investment securities reclassified into the held-to-maturity category from the available-for-sale category. Unrealized holding gains (losses) on the effective portion of the Company’s cash flow hedge derivatives are included in accumulated other comprehensive income (loss), net of applicable income taxes, which will be reclassified to interest expense as interest payments are made on the Company’s debt.
Treasury stock	TREASURY STOCK The repurchase of the Company’s common stock is recorded at cost. At the time of reissuance, the treasury stock account is reduced using the average cost method. Gains and losses on the reissuance of common stock are recorded in additional paid-in capital, to the extent additional paid-in capital from any previous net gains on treasury share transactions exists. Any net deficiency is charged to retained earnings.
Recent accounting developments	RECENT ACCOUNTING DEVELOPMENTS In August 2017, the FASB issued Accounting Standard Update (“ASU”) 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities,” which changes the recognition and presentation requirements of hedge accounting, including: eliminating the requirement to separately measure and report hedge ineffectiveness; and presenting all items that affect earnings in the same income statement line item as the hedged item. The standard also provides new alternatives for: applying hedge accounting to additional hedging strategies; measuring the hedged item in fair value hedges of interest rate risk; reducing the cost and complexity of applying hedge accounting by easing the requirements for effectiveness testing, hedge documentation and application of the critical terms match method; and reducing the risk of material error correction if a company applies the shortcut method inappropriately. This standard is effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2018 . The Company is currently evaluating the impact this standard will have on our results of operations and financial position. In May 2017, the FASB issued ASU 2017-09, “Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting,” which clarifies what constitutes a modification of a share-based payment award. This standard is effective for all entities for annual and interim periods in fiscal years beginning after December 15, 2017 . The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. 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,” which shortens the premium amortization period for purchased non-contingently callable debt securities. Shortening the amortization period is generally expected to more closely align the interest income recognition with the expectations incorporated in the market pricing on the underlying securities. This standard is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2018 . The Company is currently evaluating the impact this standard will have on our results of operations and financial position. In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which requires an entity to no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. The changes are effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2019 . All entities may early adopt the standard for goodwill impairment tests with measurement dates after January 1, 2017. The Company is currently evaluating the impact this standard will have on our results of operations and financial position. In January 2017, the FASB issued ASU 2017-03, “Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016, and November 17, 2016, EITF Meetings (SEC Update),” which incorporates into the FASB Accounting Standards Codification ® recent SEC guidance about disclosing, under SEC SAB Topic 11.M, the effect on financial statements of adopting the revenue, leases, and credit losses standards. The SEC staff had previously announced that registrants should include the disclosures starting with their December 2017 financial statements. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805),” which provides a new framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This standard is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2017 . The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” which requires companies to include cash and cash equivalents that have restrictions on withdrawal or use in total cash and cash equivalents on the statement of cash flows. This standard is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2017 . The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory,” which requires entities to recognize at the transaction date the income tax consequences of intercompany asset transfers other than inventory. This standard is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2017 . The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In September 2016, the FASB issued ASU 2016-15, “Statement of Cash Flow (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which addresses eight classification issues related to the statement of cash flows. The eight classification issues are as follows: debt prepayment or debt extinguishment costs; settlement of zero-coupon bonds; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. This standard is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2017 . Entities should apply this standard using a retrospective transition method to each period presented. If it is impracticable for an entity to apply this standard retrospectively for some of the issues, it may apply the amendments for those issues prospectively as of the earliest date practicable. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” which significantly changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life. The changes are effective for public business entities that are SEC filers, for annual and interim periods in fiscal years beginning after December 15, 2019 . The Company is currently evaluating the impact this standard will have on our results of operations and financial position. In February 2016, the FASB issued ASU 2016-02, “Leases,” which, among other things, requires lessees to recognize most leases on-balance sheet. This will increase their reported assets and liabilities - in some cases very significantly. Lessor accounting remains substantially similar to current U.S. GAAP. ASU 2016-02 supersedes Topic 840, Leases . This standard is effective for public business entities, certain not-for-profit entities, and certain employee benefit plans for annual and interim periods in fiscal years beginning after December 15, 2018 . The Company is currently evaluating the impact this standard will have on our results of operations and financial position. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” which will significantly change the income statement impact of equity investments, and the recognition of changes in fair value of financial liabilities when the fair value option is elected. This standard is effective for public business entities for interim and annual periods in fiscal years beginning after December 15, 2017 . The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” This standard implements a common approach standard that clarifies the principles for recognizing revenue. The core principle of this update is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This standard establishes a five-step model that entities must follow to recognize revenue. This update is effective for annual periods and interim periods in fiscal years beginning after December 15, 2017 , for public business entities. A significant amount of the Company’s revenues are derived from net interest income on financial assets and liabilities, which are excluded from the scope of the amended guidance. The Company is substantially complete with its overall assessment of revenue streams and review of related contracts potentially affected by the standard, including asset management fees, deposit related fees, interchange fees and merchant income. The Company’s assessment suggests that adoption of this standard should not materially change the method in which we currently recognize revenue for these revenue streams. The Company is also in the final stages of its evaluation of certain contract acquisition costs related to these revenue streams to determine whether such costs should be capitalized and deferred over the life of the contract. With respect to the capitalization of costs to acquire a contract, the Company believes adoption of this standard will likely alter the timing, measurement and recognition of those costs in the income statement; however, the Company does not expect the impact to be material. In addition, the Company is evaluating the standard’s expanded disclosure requirements. The Company plans to adopt this standard on January 1, 2018, utilizing the modified retrospective approach with a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be material.
