Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	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”), which has applied to be registered as a broker/dealer with the Securities and Exchange Commission (“SEC”) and Financial Industry Regulatory Authority (“FINRA”). The Bank was established to serve the commercial banking and private banking needs of middle-market businesses and high-net-worth individuals. Chartwell provides investment management services to institutional, sub-advisory, and separately managed account clients and had assets under management of $8.06 billion as of December 31, 2016 . CTSC Securities primary business is facilitating 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 SEC. Chartwell was established through the acquisition of substantially all the assets of Chartwell Investment Partners, LP, which was effective March 5, 2014. Chartwell was converted from a C corporation to a limited liability corporation (“LLC”), effective June 30, 2015. CTSC Securities was capitalized in May 2014, and once registered, will be a broker/dealer regulated by the SEC and 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 will conduct 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 worse 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. 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. 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 from investments over the 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 as well as 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 December 31, 2016 and 2015 . Cash and stock dividends are reported as interest income, 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 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 in 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 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 the 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 to 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. The allowance was appropriate, in management’s judgment, to cover probable losses inherent in the loan portfolio as of December 31, 2016 and 2015 . 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 components of the allowance for loan losses represent estimates based upon Accounting Standards Codification (“ASC”) Topic 450, Contingencies, and ASC Topic 310, Receivables. ASC Topic 450 applies to homogeneous loan pools such as consumer installment, residential mortgages, consumer lines of credit and commercial loans that are not individually evaluated for impairment under ASC Topic 310. ASC Topic 310 is applied to commercial and consumer loans that are individually evaluated for impairment. Under ASC Topic 310, a loan is impaired, based upon current information and events, in management’s opinion, 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 under ASC Topic 450 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, as well as the results of internal loan reviews. 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 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 under ASC Topic 450 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, consisting of commercial and industrial, commercial real estate and private banking. 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 received 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. 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 no bad debt expense recorded for the years ended December 31, 2016 , 2015 and 2014 , and there was no allowance for uncollectible accounts recorded as of December 31, 2016 and 2015 . 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 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 operating 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 and 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 and subordinated notes payable at their principal amount net of debt issuance costs, per ASU 2015-03. 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. It is the Company’s policy to recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense in the consolidated statements of income. DERIVATIVES AND HEDGING ACTIVITIES The Company accounts for derivative instruments and hedging activities in accordance with FASB ASC Topic 815, Derivatives and Hedging. All derivatives are evaluated at inception as to whether or not they are hedging or non-hedging activities, and appropriate documentation is maintained to support the final determination. 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, for all share-based awards, including stock options and restricted shares, made to employees and directors. The Company accounts for stock-based compensation in accordance with the fair value recognition provisions of ASC Topic 718, Compensation – Stock Compensation. As a result, compensation cost for all share-based payments is based on the grant-date fair value estimated in accordance with ASC Topic 718. 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 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 previous net gains on treasury share transactions exists. Any deficiency is charged to retained earnings. RECENT ACCOUNTING DEVELOPMENTS In December 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-19, “Technical Corrections and Improvements,” which amends a number of Topics in the FASB ASC. The ASU is part of an ongoing FASB project to facilitate Codification updates for non-substantive technical corrections, clarifications, and improvements that are not expected to have a significant effect on accounting practice or create a significant administrative cost to most entities. The ASU will apply to all reporting entities within the scope of the affected accounting guidance. Most amendments are effective upon issuance (December 2016). Certain amendments that require transition guidance are effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2016. Early adoption is permitted for the amendments that require transition guidance. The adoption of ASU 2016-19 did not 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 ASU is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, adjustments should be reflected at the beginning of the fiscal year that includes that interim period. The Company is currently evaluating the impact this standard will have on our results of operations and financial position. In October 2016, the FASB issued ASU 2016-17, “Consolidation (Topic 810): Interests Held through Related Parties That Are under Common Control,” which requires a single decision maker or service provider, in evaluating whether it is the primary beneficiary, to consider on a proportionate basis indirect interests held through related parties under common control. This ASU is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2016. Entities can adopt the ASU on issuance, including in an interim period. However, if an entity adopts in an interim period other than the first interim period, it should compute and reflect the cumulative effect of the accounting change as of the beginning of the fiscal year that includes that interim period. Entities that have not adopted ASU 2015-02 should adopt A

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS On April 29, 2016, TriState Capital Holdings, Inc. through its wholly-owned subsidiary, Chartwell Investment Partners, LLC, completed the acquisition of substantially all of the assets of The Killen Group, Inc. (the "TKG acquisition"), an investment management firm with approximately $2.02 billion in assets under management. Under the terms of the Asset Purchase Agreement substantially all of the assets of The Killen Group, Inc. (“TKG”) were acquired for a purchase price consisting of $15.0 million paid in cash at closing based on five-times a base EBITDA (earnings before interest, taxes, depreciation and amortization) of $3.0 million plus an earn out. The earn out, while not limited under the terms of the Asset Purchase Agreement, was calculated based on a multiple of seven-times the incremental growth in TKG's annual run-rate EBITDA over $3.0 million at December 31, 2016. The earn out was estimated, at closing, to be approximately $3.7 million based on the estimated annual run-rate EBITDA of TKG at December 31, 2016. The change to the earn out calculation from the estimated $3.7 million recorded at closing, was recorded in the statement of income during the year ended December 31, 2016. The foregoing summary of the Asset Purchase Agreement and the transactions contemplated by it does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Asset Purchase Agreement, which was included as Exhibit 2.2 to the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 16, 2016, the terms of which Agreement are incorporated herein by reference. The following table summarizes total consideration at closing, assets acquired and liabilities assumed for the TKG acquisition on April 29, 2016: (Dollars in thousands) TKG Acquisition Consideration paid: Cash $ 15,000 Estimated earn out, at closing 3,687 Fair value of total consideration, at closing $ 18,687 Fair value of assets acquired: Cash and cash equivalents $ 905 Investment management fees receivable 912 Office properties and equipment 20 Other assets 106 Total assets acquired 1,943 Fair value of liabilities assumed: Other liabilities 1,402 Total liabilities assumed 1,402 Fair value net identifiable assets acquired 541 Long-lived amortizable intangible assets acquired 13,585 Goodwill 4,561 Total net assets purchased $ 18,687 During the year ended December 31, 2016, the fair value of the estimated acquisition earn out was decreased by $3.7 million based on management’s final determination of the annualized run-rate EBITDA of TKG at December 31, 2016. This adjustment to the earn out was credited to non-interest expense during the year ended December 31, 2016. Thus, there was no remaining acquisition earn out liability as of December 31, 2016. In connection with the TKG acquisition, total acquisition-related transaction costs incurred by the Company was approximately $1,000 and $601,000 during the years ended December 31, 2016 and 2015, respectively, which were primarily comprised of legal, advisory and other costs. Since the acquisition, the TKG acquired operations contributed approximate revenues of $7.2 million and approximate earnings of $1.4 million (excluding the earn out adjustment as discussed above) which were included in the consolidated statement of income for the year ended December 31, 2016. Goodwill is not amortized for book purposes, but goodwill capitalized for tax purposes is deductible. The following table shows the amount of other intangible assets acquired through the TKG acquisition on April 29, 2016, by class and estimated useful life: (Dollars in thousands) Gross Amount Estimated Trade name $ 2,850 300 Client Relationships: Sub-advisory client list 330 132 Separate managed accounts client list 715 168 Non-compete agreements 390 48 Total finite-lived intangibles $ 4,285 242 Client Relationships: Mutual fund client relationships 9,300 Indefinite life Total intangibles assets $ 13,585 The following table presents unaudited pro forma financial information which combines the historical consolidated statements of income of the Company and The Killen Group, Inc. to give effect to the acquisition as if it had occurred on January 1, 2015, for the periods indicated: Pro Forma (unaudited) Years Ended December 31, (Dollars in thousands, except per share data) 2016 2015 Total revenue $ 124,977 $ 119,359 Net income $ 29,380 $ 23,266 Earnings per common share: Basic $ 1.06 $ 0.84 Diluted $ 1.04 $ 0.82 Total revenue is defined as net interest income and non-interest income, excluding gains and losses on the sale and call of investment securities. Pro forma adjustments include intangible amortization expense and income tax expense.

To assess for impairment on its municipal bonds, corporate bonds, single-issuer trust preferred securities, non-agency mortgage-backed securities, non-agency collateralized loan obligations and certain equity securities, 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 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.

Receivables [Abstract]
LOANS	LOANS The Company generates loans through the private banking and middle-market channels. These channels provide risk diversification and offer significant growth opportunities. The private banking channel includes loans secured by cash, marketable securities and other asset-based loans to executives, high-net-worth individuals, trusts and businesses, many of whom we source through referral relationships with independent broker/dealers, wealth managers, family offices, trust companies and other financial intermediaries. 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. Loans held-for-investment were comprised of the following: 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 Net deferred loan (fees) costs 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 December 31, 2015 (Dollars in thousands) Private Commercial Commercial Total Loans held-for-investment, before deferred fees $ 1,341,988 $ 634,857 $ 864,863 $ 2,841,708 Net deferred loan (fees) costs 2,876 (625 ) (2,675 ) (424 ) Loans held-for-investment, net of deferred fees 1,344,864 634,232 862,188 2,841,284 Allowance for loan losses (1,566 ) (11,064 ) (5,344 ) (17,974 ) Loans held-for-investment, net $ 1,343,298 $ 623,168 $ 856,844 $ 2,823,310 The Company’s customers have unused loan commitments. 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 December 31, 2016 and December 31, 2015 , was $1.75 billion and $1.27 billion , respectively. The interest rate for each commitment is based on the prevailing market conditions at the time of funding. The lending commitment maturities as of December 31, 2016 , were as follows: $1.45 billion in one year or less; $180.9 million in one to three years; and $117.2 million in greater than three years. The reserve for losses on unfunded commitments was $650,000 and $546,000 , as of December 31, 2016 and December 31, 2015 , respectively, which includes reserves for probable losses on unfunded loan commitments, including standby letters of credit and also risk participations. Included in the unfunded commitment totals listed above, were loans in the process of origination totaling approximately $59.8 million and $31.1 million as of December 31, 2016 and December 31, 2015 , 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 December 31, 2016 and December 31, 2015 , included in the total unfunded commitments above, was $77.4 million and $89.9 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. As of December 31, 2016 and December 31, 2015 , $42.3 million and $36.8 million , respectively, in standby letters of credit will expire within one year, while the remaining standby letters of credit will expire in periods greater than one year. During the year ended December 31, 2016 , there were three draws on standby letters of credit totaling $151,000 , which were immediately repaid by the borrower or converted to an outstanding loan based on the contractual terms and subsequently repaid. During the year ended December 31, 2015 , there were two standby letters of credit drawn for $146,000 which were immediately repaid by the borrower or converted to an outstanding loan based on the contractual terms and subsequently repaid. Most of these commitments are expected to expire without being drawn upon and the total amount does not necessarily represent future cash requirements. The probable 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. The risk participation agreements provide credit protection to the financial institution counterparties should the customers fail to perform on their interest rate derivative contracts. The potential liability for outstanding obligations was included in the reserve for losses on unfunded commitments. As of December 31, 2016 and December 31, 2015 , 91.1% and 91.5% , respectively, of the commercial loan portfolio was comprised of loans to customers within the Company’s primary market areas of Pennsylvania, Ohio, New Jersey, New York and contiguous states. As a result, the loan portfolio is subject to the general economic conditions within those areas. The Company evaluates each customer’s creditworthiness on an individual basis. The amount of collateral obtained by the Company upon extension of credit is based on management’s credit evaluation of the borrower. The Company does not believe it has significant concentrations of credit risk to any one group of borrowers given its underwriting and collateral requirements. The Company’s loan portfolio is comprised of amortizing loans, where scheduled principal and interest payments are applied according to the terms of the loan agreement, as well as interest-only loans. As of December 31, 2016 and December 31, 2015 , interest-only loans represented 69.0% and 67.7% of the loans held-for-investment, respectively. Of the total interest-only loans as of December 31, 2016 , 77.0% were lines of credit, 3.4% were construction loans and the remaining 19.7% were closed-end term loans which will either convert to an amortizing loan with required principal and interest payments or require a balloon payment of the total principal at maturity. Of the total interest-only loans as of December 31, 2015 , 72.9% were lines of credit, 5.7% were construction loans and the remaining 21.4% were closed-end term loans which will either convert to an amortizing loan with required principal and interest payments or require a balloon payment of the total principal at maturity. There were $1.55 billion in loans that are due on demand with no stated maturity and $1.85 billion in loans with stated maturities which have an expected average remaining maturity of approximately four years as of December 31, 2016 , compared to $1.14 billion in loans that are due on demand with no stated maturity and $1.70 billion in loans with stated maturities which have an expected average remaining maturity of approximately four years as of December 31, 2015 . 88.6% and 84.9% of the portfolio was comprised of variable rate loans as of December 31, 2016 and December 31, 2015 , respectively. Further, 2.8% of variable rate loans had interest rates below their floors, with an average interest rate of 4.59% as of December 31, 2016 , compared to 5.9% of variable rate loans had interest rates below their floors, with an average interest rate of 4.59% as of December 31, 2015 .

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 to 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 at least 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 resultant 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. Some loans are secured by residential real estate or other financial assets. The portfolio also has 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 was 91.3% and 87.8% of total private banking loans as of December 31, 2016 and 2015 , respectively. Middle -Market Banking: Commercial and Industrial Loans This loan portfolio primarily includes loans made to service companies or manufacturers generally for the purpose of production, operating capacity, accounts receivable, inventory or equipment financing, acquisitions and recapitalizations. Cash flow from the borrower’s operations is the primary source of repayment for these loans. The industry of the borrower is an important indicator of risk, but there are also more specific risks depending on the condition of the local/regional economy. Collateral for these types of loans at times does not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt. Any 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, retail, industrial, multifamily and hospitality. 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 these loans. 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 of 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. Management further assesses risk within each loan portfolio using key inherent risk differentiators. The components of the allowance for loan losses represent estimates based upon ASC Topic 450, Contingencies, and ASC Topic 310, Receivables. ASC Topic 450 applies to homogeneous loan pools such as consumer installment, residential mortgages and consumer lines of credit, as well as commercial loans that are not individually evaluated for impairment under ASC Topic 310. Impaired loans are individually evaluated for impairment under ASC Topic 310. On a monthly basis, management monitors various credit quality indicators for both the commercial and consumer loan portfolios, 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 margin 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. Management continually monitors the loan portfolio through its internal risk rating system. Loan risk ratings are assigned based upon the creditworthiness of the borrower and the quality of the collateral for our 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 risk rated as special mention, substandard and doubtful, which are believed to have an increasing risk of loss. 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. The following tables present the recorded investment in loans by credit quality indicator: December 31, 2016 (Dollars in thousands) Private Commercial Commercial Total Pass $ 1,735,404 $ 545,276 $ 1,077,703 $ 3,358,383 Special mention — 18,776 — 18,776 Substandard 524 23,371 — 23,895 Doubtful — — — — Loans held-for-investment $ 1,735,928 $ 587,423 $ 1,077,703 $ 3,401,054 December 31, 2015 (Dollars in thousands) Private Commercial Commercial Total Pass $ 1,342,813 $ 585,561 $ 858,396 $ 2,786,770 Special mention — 31,863 880 32,743 Substandard 2,051 15,835 2,912 20,798 Doubtful — 973 — 973 Loans held-for-investment $ 1,344,864 $ 634,232 $ 862,188 $ 2,841,284 Changes in the allowance for loan losses were as follows for the years ended December 31, 2016 , 2015 and 2014 : Year Ended December 31, 2016 (Dollars in thousands) Private Commercial Commercial Total Balance, beginning of period $ 1,566 $ 11,064 $ 5,344 $ 17,974 Provision (credit) for loan losses (142 ) 4,723 (3,743 ) 838 Charge-offs — (4,258 ) — (4,258 ) Recoveries — 797 3,411 4,208 Balance, end of period $ 1,424 $ 12,326 $ 5,012 $ 18,762 Year Ended December 31, 2015 (Dollars in thousands) Private Commercial Commercial Total Balance, beginning of period $ 2,017 $ 13,501 $ 4,755 $ 20,273 Provision (credit) for loan losses (464 ) (112 ) 589 13 Charge-offs — (3,353 ) — (3,353 ) Recoveries 13 1,028 — 1,041 Balance, end of period $ 1,566 $ 11,064 $ 5,344 $ 17,974 Year Ended December 31, 2014 (Dollars in thousands) Private Commercial Commercial Total Balance, beginning of period $ 2,011 $ 11,881 $ 5,104 $ 18,996 Provision (credit) for loan losses (88 ) 10,596 (349 ) 10,159 Charge-offs — (9,521 ) — (9,521 ) Recoveries 94 545 — 639 Balance, end of period $ 2,017 $ 13,501 $ 4,755 $ 20,273 Charge-offs of $4.3 million for the year ended December 31, 2016 , included one C&I loan, which were mostly offset by recoveries of $4.2 million on six C&I loans and one CRE loan.

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.

There was no interest income recognized, while on non-accrual status, for the years ended December 31, 2016 , 2015 and 2014 . As of December 31, 2016 and December 31, 2015 , there were no loans 90 days or more past due and still accruing interest income. Impaired loans were evaluated using a discounted cash flow method or based on the fair value of the collateral less estimated selling costs. Based on those evaluations, as of December 31, 2016 , there were specific reserves totaling $6.9 million , which were included in the $18.8 million allowance for loan losses. Also included in impaired loans was one C&I loan with a balance of $471,000 as of December 31, 2016 , with no corresponding specific reserve since this loan had a net realizable value that management believes will be recovered from the borrower.

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 December 31, 2016 and December 31, 2015 , 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 Total risk-based, Tier 1 risk-based, CET 1 risk-based capital ratios and Tier 1 leverage ratio (Tier 1 capital to average assets) as set forth in the tables below. Based upon the information in the most recently filed Call Report, 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 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. In addition, 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).

STOCK TRANSACTIONS	STOCK TRANSACTIONS In October 2014, the Board of Directors authorized the repurchase of up to $10 million , or up to 1,000,000 shares, of the Company’s common stock through December 31, 2015. Under this plan, the Company repurchased a total of 1,000,000 shares during the years ended December 31, 2015 and 2014, for approximately $9.9 million , at an average cost of $9.90 per share, which are held as treasury stock. In January 2016, the Board of Directors authorized the repurchase of up to $10 million of the Company’s common stock. Also, in October 2016, the Board of Directors authorized the repurchase of up to an additional $5 million of the Company’s common stock. During the year ended December 31, 2016 , the Company repurchased a total of 374,729 shares for approximately $5.1 million , at an average cost of $13.68 per share, which are held as treasury stock. The Board subsequently authorized the Company to utilize some of the combined $15 million allocated to these share repurchase programs to cancel options granted by the Company to purchase shares of its common stock that expire in 2017. In accordance with that authorization, in addition to the shares purchased as described in this paragraph, the Company and holders of options that expire in 2017 agreed to cancel options as set forth in the following paragraph. The approximate dollar value of shares that may yet be purchased under these share repurchase programs have been reduced by the amount expended in connection with the option cancellations. During the year ended December 31, 2016 , the Company’s Board of Directors approved a stock option cancellation program to allow for outstanding and vested stock option awards granted in 2007 and expiring in 2017 to be canceled by the option holder at a price based on the closing day’s stock price less the option exercise price. During the year ended December 31, 2016 , there were 1,174,500 options canceled for $6.2 million , which was recorded as a reduction to additional paid-in capital. The table below shows the changes in the Company’s common shares outstanding during the periods indicated: Number of Balance, December 31, 2013 28,690,279 Issuance of restricted common stock 27,000 Forfeitures of restricted common stock — Exercise of stock options 22,500 Purchase of treasury stock (678,891 ) Balance, December 31, 2014 28,060,888 Issuance of restricted common stock 282,916 Forfeitures of restricted common stock (4,000 ) Exercise of stock options 37,500 Purchase of treasury stock (321,109 ) Balance, December 31, 2015 28,056,195 Issuance of restricted common stock 497,309 Forfeitures of restricted common stock (13,121 ) Exercise of stock options 250,000 Purchase of treasury stock (374,729 ) Balance, December 31, 2016 28,415,654

STOCK-BASED COMPENSATION PROGRAMS	STOCK-BASED COMPENSATION PROGRAMS The Company’s 2006 Stock Option Plan (the “2006 Plan”) provided for the granting of incentive and non-qualifying stock options to the Company’s key employees, key contractors and outside directors at the discretion of the Board of Directors. The Omnibus Incentive Plan (the “Omnibus Plan”), which was approved by TriState Capital’s shareholders on May 20, 2014, provides for the granting of incentive and non-qualifying stock options, stock appreciation rights, restricted shares, restricted stock units, dividend equivalent rights and other equity-based or equity-related awards to the Company’s key employees, key contractors and outside directors at the discretion of the Board of Directors. The Omnibus Plan, upon its approval, replaced the 2006 Plan. The total number of shares of common stock that may be granted under the Omnibus Plan is the number of authorized shares of common stock of TriState Capital remaining available under the 2006 Plan as of the date of shareholder approval, plus any shares of common stock issued pursuant to the 2006 Plan that were forfeited, canceled, expired or otherwise terminated. The shares reserved for grants under the 2006 Plan shall no longer be available for grants under that plan, but shall instead be reserved for grants under the Omnibus Plan. The total common shares, authorized by shareholders of the Company, relating to stock-based awards which may be issued upon the grant or exercise of stock-based awards was 4,000,000 , as of December 31, 2016 , under both the 2006 Plan and the Omnibus Plan (combined the “Plans”). As of December 31, 2016 , the Company has issued non-qualifying stock options and restricted shares. The aggregate awards outstanding were 1,916,698 under both of the Plans. 329,299 stock options and restricted shares have been exercised or vested, respectively, leaving 1,754,003 additional awards available for the Company to grant under the Omnibus Plan as of December 31, 2016 . The Company’s stock option grants contain terms that provide for a graded vesting schedule whereby portions of the options vest in increments over the requisite service period. Options issued under the Plans typically vest either 50 percent after two and one-half years following the award date and the remaining 50 percent five years following the award date; or 100 percent after five years following the award date. Restricted shares under the Omnibus Plan typically vest 100 percent after three years following the award date. The Company recognizes compensation expense for awards with graded vesting schedules on a straight-line basis over the requisite service period for the entire grant. The Company’s compensation expense for all awards was $3.6 million , $1.9 million and $896,000 for the years ended December 31, 2016 , 2015 and 2014 , respectively. In 2016 and 2015, the Company’s Board of Directors approved stock option cancellation programs to allow for outstanding and vested stock option awards granted in 2007 to be canceled by the option holder at a price based on the closing day’s stock price less the option exercise price. During the year ended December 31, 2016 , there were 1,174,500 options canceled for $6.2 million , which was recorded as a reduction to additional paid-in capital. During the year ended December 31, 2015 , there were 77,000 options canceled for $229,000 , which was recorded as a reduction to additional paid-in capital. Stock Options The fair value of each option award is estimated on the date of the grant using the Black-Scholes option pricing model and the weighted average assumptions in the following table. Expected term was calculated utilizing the simplified method because the Company has limited historical exercise behavior. Since the Company is newly publicly traded and there is not enough trading history, expected volatility is computed based on median historical volatility of similar entities with publicly traded shares. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The computation assumes that there will be no dividends paid to common shareholders during the contractual life of the options.

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 December 31, 2016 and December 31, 2015 : 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 Asset Derivatives Liability Derivatives as of December 31, 2015 as of December 31, 2015 (Dollars in thousands) Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives designated as hedging instruments: Interest rate products Other assets $ — Other liabilities $ 229 Derivatives not designated as hedging instruments: Interest rate products Other assets $ 8,662 Other liabilities $ 9,363 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 December 31, 2016 , the Company had four interest rate swaps, with an aggregate notional amount of $2.8 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, however, credit risk was considered insignificant for the years ended December 31, 2016 and 2015 . There were no counterparty default losses on derivatives for the years ended December 31, 2016 and 2015 . 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. During the year ended December 31, 2016 , the Company recognized a net gain of $4,000 in non-interest income related to hedge ineffectiveness as compared to net gains of $3,000 and $10,000 during the years ended December 31, 2015 and 2014 , respectively. The Company also recognized a decrease to interest income of $88,000 for the year ended December 31, 2016 , related to the Company’s fair value hedges, which includes net settlements on the derivatives, and any amortization adjustment of the basis in the hedged items as compared to decreases to interest income of $294,000 and $321,000 during the years ended December 31, 2015 and 2014 , respectively. 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 year ended December 31, 2016 . 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 year ended December 31, 2016 , there was an increase to interest expense of $43,000 . During the next twelve months, the Company estimates $345,000 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 30 months . As of December 31, 2016 , 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 year ended December 31, 2016 , a net gain of $1.8 million was recognized in accumulated other comprehensive income (loss) on the effective portion of the derivative. 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 December 31, 2016 , the Company had 224 derivative transactions with an aggregate notional amount of $954.2 million related to this program. During the year ended December 31, 2016 , the Company recognized a net gain of $528,000 related to changes in fair value of the derivatives not designated in hedging relationships, as compared to net losses of $174,000 and $423,000 during the years ended December 31, 2015 and 2014 , respectively. EFFECT OF DERIVATIVE INSTRUMENTS IN THE STATEMENTS OF INCOME The tables below present the effect of the Company’s derivative financial instruments in the consolidated statements of income for the periods presented: Years Ended December 31, (Dollars in thousands) 2016 2015 2014 Derivatives designated as hedging instruments: Location of Gain (Loss) Recognized in Amount of Gain (Loss) Interest rate products Interest income $ (88 ) $ (294 ) $ (321 ) Non-interest income 4 3 10 Interest expense (43 ) — — Total $ (127 ) $ (291 ) $ (311 ) Derivatives not designated as hedging instruments: Location of Gain (Loss) Recognized in Amount of Gain (Loss) Interest rate products Non-interest income $ 528 $ (174 ) $ (423 ) Total $ 528 $ (174 ) $ (423 ) 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 December 31, 2016 , the termination value of derivatives, including accrued interest, in a net liability position related to these agreements was $902,000 . As of December 31, 2016 , the Company has minimum collateral posting thresholds with certain of its derivative counterparties and has posted collateral of $5.3 million . If the Company had breached any of these provisions as of December 31, 2016 , 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 December 31, 2016 and December 31, 2015 : 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 December 31, 2015 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets / Financial assets: Investment securities available-for-sale: Corporate bonds $ — $ 43,733 $ — $ 43,733 Trust preferred securities — 16,601 — 16,601 Non-agency mortgage-backed securities — 5,743 — 5,743 Non-agency collateralized loan obligations — 11,711 — 11,711 Agency collateralized mortgage obligations — 49,371 — 49,371 Agency mortgage-backed securities — 28,669 — 28,669 Agency debentures — 4,732 — 4,732 Equity securities 7,759 — — 7,759 Interest rate swaps — 8,662 — 8,662 Total financial assets 7,759 169,222 — 176,981 Financial liabilities: Interest rate swaps — 9,592 — 9,592 Total financial liabilities $ — $ 9,592 $ — $ 9,592 INVESTMENT SECURITIES Generally, investment securities are valued using pricing for similar securities, recently executed transactions and other pricing models utilizing observable inputs. The valuations for debt and equity securities are classified as either Level 1 or Level 2. U.S. Treasury Notes and equity securities (including mutual funds) are classified as Level 1 because these securities are in actively traded markets. Investment securities within Level 2 include corporate bonds; single-issuer trust preferred securities; non-agency mortgage-backed securities and collateralized loan obligations; collateralized mortgage obligations, mortgage-backed securities, and debentures issued by U.S. government agencies. 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 December 31, 2016 and December 31, 2015 : 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 December 31, 2015 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets Loans measured for impairment, net $ — $ — $ 12,625 $ 12,625 Other real estate owned — — 1,730 1,730 Total assets $ — $ — $ 14,355 $ 14,355 As of December 31, 2016 and December 31, 2015 , the Company recorded $6.9 million and $4.5 million , respectively, of specific reserves to the 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 flow 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 recovered 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 recovered value may be less than the independent appraised value. Accordingly, 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 December 31, 2016 and December 31, 2015 : December 31, 2016 (Dollars in thousands) Fair Value Valuation Techniques (1) Significant Unobservable Inputs Weighted Average Discount Rate 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. December 31, 2015 (Dollars in thousands) Fair Value Valuation Techniques (1) Significant Unobservable Inputs Weighted Average Discount Rate Loans measured for impairment, net $ 5,428 Appraisal value or Liquidation analysis Discount due to salability conditions 14 % Loans measured for impairment, net $ 7,197 Discounted cash flow Discount due to restructured nature of operations 7 % Other real estate owned $ 1,730 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. FAIR VALUE OF FINANCIAL INSTRUMENTS A summary of the carrying amounts and estimated fair values of financial instruments was as follows: December 31, 2016 December 31, 2015 (Dollars in thousands) Fair Value Carrying Estimated Carrying Estimated Financial assets: Cash and cash equivalents 1 $ 103,994 $ 103,994 $ 96,676 $ 96,676 Investment securities available-for-sale: debt 2 166,540 166,540 160,560 160,560 Investment securities available-for-sale: equity 1 8,352 8,352 7,759 7,759 Investment securities held-to-maturity 2 53,940 54,498 47,290 48,099 Federal Home Loan Bank stock 2 9,641 9,641 9,802 9,802 Loans held-for-investment, net 3 3,382,292 3,362,031 2,823,310 2,813,278 Accrued interest receivable 2 9,614 9,614 7,056 7,056 Investment management fees receivable 2 7,749 7,749 6,191 6,191 Bank owned life insurance 2 64,815 64,815 60,019 60,019 Interest rate swaps 2 12,117 12,117 8,662 8,662 Other real estate owned 3 4,178 4,178 1,730 1,730 Financial liabilities: Deposits 2 3,286,779 3,286,553 2,689,844 2,690,693 Borrowings, net 2 239,510 240,143 254,308 255,179 Interest rate swaps 2 10,609 10,609 9,592 9,592 During the years ended December 31, 2016 , 2015 and 2014 , there were no transfers between fair value Levels 1, 2 or 3. The following methods and assumptions were used to estimate the fair value of each class of financial instruments as of December 31, 2016 and December 31, 2015 : 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 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.

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 worse 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. 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.
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 from investments over the 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 as well as 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 December 31, 2016 and 2015 . Cash and stock dividends are reported as interest income, 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 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 in 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 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 the 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 to 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. The allowance was appropriate, in management’s judgment, to cover probable losses inherent in the loan portfolio as of December 31, 2016 and 2015 . 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 components of the allowance for loan losses represent estimates based upon Accounting Standards Codification (“ASC”) Topic 450, Contingencies, and ASC Topic 310, Receivables. ASC Topic 450 applies to homogeneous loan pools such as consumer installment, residential mortgages, consumer lines of credit and commercial loans that are not individually evaluated for impairment under ASC Topic 310. ASC Topic 310 is applied to commercial and consumer loans that are individually evaluated for impairment. Under ASC Topic 310, a loan is impaired, based upon current information and events, in management’s opinion, 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 under ASC Topic 450 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, as well as the results of internal loan reviews. 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 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 under ASC Topic 450 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, consisting of commercial and industrial, commercial real estate and private banking. 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 received 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. 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 no bad debt expense recorded for the years ended December 31, 2016 , 2015 and 2014 , and there was no allowance for uncollectible accounts recorded as of December 31, 2016 and 2015 .
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 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 operating 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 and 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 and subordinated notes payable at their principal amount net of debt issuance costs, per ASU 2015-03. 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. It is the Company’s policy to recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense in the consolidated statements of income.
Derivates and hedging activities	DERIVATIVES AND HEDGING ACTIVITIES The Company accounts for derivative instruments and hedging activities in accordance with FASB ASC Topic 815, Derivatives and Hedging. All derivatives are evaluated at inception as to whether or not they are hedging or non-hedging activities, and appropriate documentation is maintained to support the final determination. 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, for all share-based awards, including stock options and restricted shares, made to employees and directors. The Company accounts for stock-based compensation in accordance with the fair value recognition provisions of ASC Topic 718, Compensation – Stock Compensation. As a result, compensation cost for all share-based payments is based on the grant-date fair value estimated in accordance with ASC Topic 718. 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 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 previous net gains on treasury share transactions exists. Any deficiency is charged to retained earnings.
Recent accounting developments	RECENT ACCOUNTING DEVELOPMENTS In December 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-19, “Technical Corrections and Improvements,” which amends a number of Topics in the FASB ASC. The ASU is part of an ongoing FASB project to facilitate Codification updates for non-substantive technical corrections, clarifications, and improvements that are not expected to have a significant effect on accounting practice or create a significant administrative cost to most entities. The ASU will apply to all reporting entities within the scope of the affected accounting guidance. Most amendments are effective upon issuance (December 2016). Certain amendments that require transition guidance are effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2016. Early adoption is permitted for the amendments that require transition guidance. The adoption of ASU 2016-19 did not 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 ASU is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, adjustments should be reflected at the beginning of the fiscal year that includes that interim period. The Company is currently evaluating the impact this standard will have on our results of operations and financial position. In October 2016, the FASB issued ASU 2016-17, “Consolidation (Topic 810): Interests Held through Related Parties That Are under Common Control,” which requires a single decision maker or service provider, in evaluating whether it is the primary beneficiary, to consider on a proportionate basis indirect interests held through related parties under common control. This ASU is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2016. Entities can adopt the ASU on issuance, including in an interim period. However, if an entity adopts in an interim period other than the first interim period, it should compute and reflect the cumulative effect of the accounting change as of the beginning of the fiscal year that includes that interim period. Entities that have not adopted ASU 2015-02 should adopt ASU 2016-17 at the same time and apply the same transition method for both standards. Entities that already adopted ASU 2015-02 should apply ASU 2016-17 retrospectively to all periods beginning with the earliest annual period in which they adopted ASU 2015-02. The adoption of ASU 2016-17 did not 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 ASU is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2017. Entities may early adopt the ASU, but only at the beginning of an annual period for which no financial statements (interim or annual) have already been issued or made available for issuance. The Company is currently evaluating the impact this standard will have on our results of operations and financial position. In September of 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 ASU is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the ASU in an interim period, adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. Entities should apply this ASU using a retrospective transition method to each period presented. If it is impracticable for an entity to apply the ASU retrospectively for some of the issues, it may apply the amendments for those issues prospectively as of the earliest date practicable. The Company is currently evaluating the impact this standard will have on our results of operations and financial position. 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. All entities may early adopt the standard 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 March 2016, the FASB issued ASU 2016-09, “ Improvements to Employee Share-Based Payment Accounting,” which is intended to improve the accounting for share-based payment transactions as part of the FASB’s simplification initiative. The ASU changes seven aspects of the accounting for share-based payment award transactions, including: (1) accounting for income taxes; (2) classification of excess tax benefits on the statement of cash flows; (3) forfeitures; (4) minimum statutory tax withholding requirements; (5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes; (6) practical expedient - expected term (nonpublic only); and (7) intrinsic value (nonpublic only). The ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those years for public business entities. Early adoption is permitted in any interim or annual period provided that the entire ASU is adopted. Even if an entity early adopts the amendments after the first interim period, the adoption date is as of the beginning of the year for the issues adopted by the cumulative-effect and prospective methods. Any adjustments to previously reported interim periods of that fiscal year should be included in the year-to-date results. If those previously reported interim results appear in any future filings, they are reported on the revised basis. The adoption of ASU 2016-09 did not have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU 2016-06, “ Contingent Put and Call Options in Debt Instruments,” which clarifies that determining whether the economic characteristics of a put or call are clearly and closely related to its debt host requires only an assessment of the four-step decision sequence outlined in FASB ASC paragraph 815-15-25-24. Additionally, entities are not required to separately assess whether the contingency itself is clearly and closely related. ASU 2016-06 is effective for public business entities for interim and annual periods in fiscal years beginning after December 15, 2016. Early adoption is permitted in any interim period for which the entity’s financial statements have not been issued but would be retroactively applied to the beginning of the year that includes that interim period. The adoption of ASU 2016-06 did not have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU 2016-05, “ Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships,” which clarifies that a change in one of the parties to a derivative contract (through novation) that is part of a hedge accounting relationship does not, by itself, require dedesignation of that relationship, as long as all other hedge accounting criteria continue to be met. This ASU is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2016. Early adoption is permitted, including adoption in an interim period. The adoption of ASU 2016-05 did not have a material impact on the Company’s consolidated financial statements. 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 . ASU 2016-02 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. This ASU mandates a modified retrospective transition method for all entities. 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. The ASU is effective for public business entities for interim and annual periods in fiscal years beginning after December 15, 2017. The Company is currently evaluating the impact this standard will have on our results of operations and financial position. In September 2015, the FASB issued ASU 2015-16, “ Business Combinations (Topic 805): Simplifying the Accounting for Measurement Period Adjustments.” This ASU eliminated the requirement for an acquirer to retrospectively adjust the financial statements for measurement-period adjustments that occur in periods after a business combination is consummated. The ASU was effective for public business entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. The adoption of ASU 2015-16 did not have a material impact on the Company’s consolidated financial statements. In June 2015, the FASB issued ASU 2015-10, “ Technical Correction and Improvements,” which, among other things, corrects the initial codification of FASB Statement No. 140, “ Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities (as Amended by FASB Statement No. 166, Accounting for Transfers of Financial Assets) .” The initial codification inadvertently added the word “public” to paragraph 860-10-50-7, which was not in the original guidance. The ASU also clarifies that the requirement relates to “involvement by others”. This amendment in ASU 2015-10 was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The adoption of ASU 2015-10 did not have a material impact on the Company’s consolidated financial statements. In May 2015, the FASB issued ASU 2015-07, “ Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). ” This ASU eliminated the requirement to categorize investments in the fair value hierarchy if their fair value is measured at net asset value (NAV) per share (or its equivalent) using the practical expedient in the FASB’s fair value measurement guidance. Reporting entities were required to adopt the ASU retrospectively. The effective date for public business entities was fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The adoption of ASU 2015-07 did not have a material impact on the Company’s consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” This ASU requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs were not affected by the amendments in this update. For public business entities, the amendments in this update were effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. An entity should apply the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented was adjusted to reflect the period-specific effects of applying the new guidance. Upon transition, an entity was required to comply with the applicable disclosures for a change in an accounting principle. These disclosures included the nature of and reason for the change in accounting principle, the transition method, a description of the prior-period information that had been retrospectively adjusted, and the effect of the change on the financial statement line items (that is, debt issuance cost asset and the debt liability). The adoption of ASU 2015-03 did not have a material impact on the Company’s consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” This ASU changed the way reporting enterprises evaluate whether (a) they should consolidate limited partnerships and similar entities, (b) fees paid to a decision maker or service provider are variable interests in a variable interest entity (VIE), and (c) variable interests in a VIE held by related parties of the reporting enterprise require the reporting enterprise to consolidate the VIE. It also eliminated the VIE consolidation model based on majority exposure to variability that applied to certain investment companies and similar entities. The new guidance excludes money market funds that are required to comply with Rule 2a-7 of the Investment Company Act of 1940 and similar entities from the U.S. GAAP consolidation requirements. The new consolidation guidance was effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2015. At the effective date, all previous consolidation analyses that the guidance affects was required to be reconsidered. This included the consolidation analyses for all VIEs and for all limited partnerships and similar entities that previously were consolidated by the general partner even though the entities were not VIEs. The adoption of ASU 2015-02 did not have a material impact on the Company’s consolidated financial statements. In January 2015, the FASB issued ASU 2015-01, “Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” This ASU eliminated the concept of extraordinary items from U.S. GAAP as part of its simplification initiative. The ASU did not affect disclosure guidance for events or transactions that are unusual in nature or infrequent in their occurrence. The ASU was effective for interim and annual periods in fiscal years beginning after December 15, 2015. The ASU allowed prospective or retrospective application. The effective date was the same for both public entities and all other entities. The adoption of ASU 2015-01 did not have a material impact on the Company’s consolidated financial statements. In November 2014, the FASB issued ASU 2014-16, “Derivatives and Hedging (Topic 815),” required an entity to determine the nature of the host contract by considering the economic characteristics and risks of the entire hybrid financial instrument issued in the form of a share, including the embedded derivative feature that is being evaluated for separate accounting from the host contract when evaluating whether the host contract is more akin to debt or equity. In evaluating the stated and implied substantive terms and features, the existence or omission of any single term or feature does not necessarily determine the economic characteristics and risks of the host contract. Although an individual term or feature may weigh more heavily in the evaluation on the basis of facts and circumstances, an entity should use judgment based on an evaluation of all the relevant terms and features. This ASU was effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The effects of initially adopting the amendments should be applied on a modified retrospective basis to existing hybrid financial instruments issued in the form of a share as of the beginning of the fiscal year for which the amendment is effective. Retrospective application was permitted to all relevant prior periods. The adoption of ASU 2014-16 did not have a material impact on the Company’s consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” This ASU describes how an entity’s management should assess whether there are conditions and events that raise substantial doubt about an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Management should consider both quantitative and qualitative factors in making its assessment. If after considering management’s plans, substantial doubt about an entity’s going concern is alleviated, an entity shall disclose information in the footnotes that enables the users of the financial statements to understand the events that raised the going concern and how management’s plan alleviated this concern. If after considering management’s plans, substantial doubt about an entity’s going concern is not alleviated, the entity shall disclose in the footnotes indicating that a substantial doubt about the entity’s going concern exists within one year of the date of the issued financial statements. Additionally, the entity shall disclose the events that led to this going concern and management’s plans to mitigate them. The new standard applies to all entities for the annual period ending after December 15, 2016, and for annual and interim periods thereafter. Early application is permitted. The adoption of ASU 2014-15 did not have a material impact on the Company’s consolidated financial statements. In June 2014, the FASB issued ASU 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performing Target Could Be Achieved after the Requisite Service Period.” This ASU requires a reporting entity to treat a performance target that affects vesting and that could be achieved after the requisite service period as a performance condition. A reporting entity should apply FASB ASC Topic 718, Compensation-Stock Compensation , to awards with performance conditions that affect vesting. This update was effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015, for all entities. ASU 2014-12 may be adopted either prospectively for share-based payment awards granted or modified on or after the effective date, or retrospectively, using a modified retrospective approach. The modified retrospective approach would apply to share-based payment awards outstanding as of the beginning of the earliest annual period presented in the financial statements on adoption, and to all new or modified awards thereafter. The adoption of ASU 2014-12 did not 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 ASU implements a common revenue 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. ASU 2014-09 establishes a five-step model that entities must follow to recognize revenue and removes inconsistencies and weaknesses in existing guidance. Per ASU 2015-14, this update is effective for annual periods and interim periods within fiscal years beginning after December 15, 2017, for public business entities, certain employee benefit plans, and certain not-for-profit entities applying U.S. GAAP. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating the impact this standard will have on our results of operations and financial position.
