SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	NATURE OF OPERATION
	TriState Capital Holdings, Inc. (the “Company”) is a registered bank holding company pursuant to the Bank Holding Company Act of 1956, as amended. The Company’s has three wholly-owned subsidiaries: TriState Capital Bank (the “Bank”), a Pennsylvania-chartered state bank, Chartwell Investment Partners, Inc. ("Chartwell"), a registered investment advisory company, and Chartwell TSC Securities Corp. ("CTSC Securities"), which is applying to be registered as a broker-dealer with the Securities and Exchange Commission ("SEC") and Financial Industry Regulatory Authority ("FINRA"). Chartwell Investment Partners, Inc. was established through the acquisition of substantially all the assets of Chartwell Investment Partners, LP, which was effective March 5, 2014.
	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. Chartwell TSC Securities Corp. was capitalized in May 2014, with a primary business of providing distribution and marketing efforts for the proprietary investment products provided by Chartwell, including shares of mutual funds advised and/or administered by Chartwell and private 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. CTSC Securities, 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; Princeton, 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.
	On May 14, 2013, the Company completed the issuance and sale of 6,355,000 shares of its common stock, no par value, in its initial public offering of Common Stock, including 855,000 shares sold pursuant to the exercise in full by its underwriters of their option to purchase additional shares from the Company, at a price to the public of $11.50 per share. The shares were offered pursuant to the Company’s Registration Statement on Form S-1. The Company received net proceeds of $66.0 million from the initial public offering, after deducting underwriting discounts and commissions and direct offering expenses.
	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, goodwill, evaluation of goodwill 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 (since the acquisition on March 5, 2014) and CTSC Securities (since its initial capitalization in May 2014), after elimination of inter-company accounts and transactions. The accounts of the Bank, in turn, include its wholly-owned subsidiary, Meadowood Asset Management, LLC, after elimination of inter-company accounts and transactions. The unaudited consolidated financial statements of the Company presented herein have been prepared pursuant to rules of the Securities and Exchange Commission for quarterly reports on form 10-Q and do not include all of the information and note disclosures required by GAAP for a full year presentation. In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures, considered necessary for the fair presentation of the accompanying consolidated financial statements, have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2013, included in the Company's Annual Report on Form 10-K.
	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 which 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 changes in fair value reported as a component of accumulated other comprehensive income (loss).
	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 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. Impaired debt securities are determined to be other-than-temporarily impaired (“OTTI”) if the Company concludes as of the balance sheet date that it has the intent to sell, or believes it will more likely than not be required to sell, an impaired debt security before a recovery of its amortized cost basis. Credit losses on OTTI debt securities are recorded through earnings, regardless of the intent or the requirement to sell. Credit loss is measured as the difference between the present value of an impaired debt security’s expected cash flows and its amortized cost basis. Non-credit related OTTI charges are recorded as decreases to accumulated other comprehensive income (loss), in the consolidated statement of comprehensive income as well as the shareholders’ equity section of the consolidated statement of financial condition, on an after-tax basis, as long as the Company has no intent or expected requirement to sell the impaired debt security before a recovery of its amortized cost basis.
	LOANS
	Loans and leases are stated at unpaid principal balances, net of deferred loan fees and costs. 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 modified 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.
	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 unpaid accrued 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 and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the total 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, other than bank premises, is recorded at the lower of the related original loan balance or fair value less estimated selling costs at the time of acquisition. Fair value is determined based on an independent appraisal. Expenses related to holding the property are charged against earnings in the current period. 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 charged to operations. Loans are charged 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 is appropriate, in management's judgment, to cover probable losses inherent in the loan portfolio as of September 30, 2014 and December 31, 2013. 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 future cash flows 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-off rates 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. 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 channels. As the loan loss history, mix, and risk rating 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 may impact 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 which drives the secondary factor. There are nine (9) 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. The impact of each risk factor 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.
	Loan participations follow the same underwriting and risk rating criteria, and are individually risk rated under the same process as loans directly originated by the Company. The ongoing credit review of participation loans follows the same process that is followed by loans originated directly by the Company. Additionally, management does not rely solely on information from the lead bank when considering the appropriate level of allowance for loan losses to be recorded on any individual participation loan.
	The Company also maintains a reserve for losses on unfunded commitments. This reserve is reflected as a component of other liabilities and, in management’s judgment, is sufficient to cover probable losses inherent in the commitments. Management tracks the level and trends in unused commitments and takes into consideration the same factors as those considered for purposes of the allowance for loan losses on outstanding loans.
	INVESTMENT MANAGEMENT FEES
	The Company recognizes investment management fee revenue when the advisory services are performed. Fees are based on assets under management and are calculated pursuant to individual client contracts. Investment management fees are generally paid on a quarterly basis. In a limited number of cases, the Company may earn a performance fee based on investment performance achieved versus a stated benchmark. In such cases, performance fees are not recognized until the end of the stated measurement period. Performance fees are included in investment management fee revenue in the consolidated statements of income.
	Investment management fees receivable represent amounts due from contractual investment advisory 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 nine months ended September 30, 2014, and there was no allowance for uncollectible accounts recorded as of September 30, 2014.
	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. Cash and stock dividends are reported as income from investment securities, in the consolidated statements of income.
	BUSINESS COMBINATIONS
	We account 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.
	GOODWILL AND OTHER INTANGIBLE ASSETS
	Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. Other intangible assets that have finite lives, such as trade name, client relationships and non-compete agreements are amortized over their estimated useful lives and subject to periodic impairment testing. Other intangible assets are amortized on a straight-line basis over their estimated useful lives which range from four to twenty years. Goodwill is subject to impairment testing at the reporting unit level, which is conducted at least annually.
	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 which 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 executive 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 or expense in the consolidated statements of income.
	DEPOSITS
	Deposits are stated at principal outstanding and interest on deposits is accrued and charged to 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. Interest expense is recognized based on the coupon rate of the obligations. Costs associated with the acquisition of subordinated notes payable are amortized over the expected term of the borrowing.
	EARNINGS PER COMMON SHARE
	We compute earnings per common share (“EPS”) in accordance with the two-class method, which requires that any Series C convertible preferred stock outstanding be treated as participating securities in the computation of EPS. The two-class method is an earnings allocation that determines EPS for each class of common stock and participating security. The Company’s basic EPS is computed by dividing net income allocable to common shareholders by the weighted average number of its common shares outstanding for the period. The Company’s diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings.
	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 statement of income.
	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 stock, made to employees and directors.
	The Company accounts for stock-based employee compensation in accordance with the fair value recognition provisions of ASC 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 718. The value of the portion of the award that is ultimately expected to vest is included in stock-based employee compensation cost in the consolidated statement of income and recorded as a component of Additional Paid-In Capital, for equity-based awards. Compensation expense for options with graded vesting schedules is recognized on a straight-line basis over the requisite service period for the entire option 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.
RECENT ACCOUNTING DEVELOPMENTS
In August 2014, the FASB issued Accounting Standards Update ("ASU") No. 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 first annual period ending after December 15, 2016, and for annual and interim periods thereafter. Early application is permitted. The adoption of ASU 2014-15 is not expected to have a material impact on the Company’s consolidated financial statements.
In August 2014, the FASB issued ASU No. 2014-14, "Receivables - Troubled Debt Restructuring by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure." This ASU will require creditors to derecognize certain foreclosed government-guaranteed mortgage loans and to recognize a separate other receivable that is measured at the amount the creditor expects to recover from the guarantor, and to treat the guarantee and the receivable as a single unit of account. This update is effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. An entity can elect a prospective or a modified retrospective transition method, but must use the same transition method that it elected under FASB ASU No. 2014-04, "Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure." Early adoption, including adoption in an interim period, is permitted if the entity already adopted ASU 2014-04. The adoption of ASU 2014-14 is not expected to have a material impact on the Company’s consolidated financial statements.
In June 2014, the FASB issued ASU No. 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 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015, for all entities. Early adoption is permitted. 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 is not expected to have a material impact on the Company’s consolidated financial statements.
In January 2014, the FASB issued ASU No. 2014-04, "Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure." This ASU clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2014 and December 15, 2015, for public and nonpublic entities, respectively. Early adoption and retrospective application are permitted. The adoption of ASU 2014-04 is not expected to have a material impact on the Company’s consolidated financial statements.

	On March 5, 2014, TriState Capital Holdings, Inc. through its wholly-owned subsidiary, Chartwell Investment Partners, Inc., completed the acquisition of substantially all of the assets of Chartwell Investment Partners, LP (the "Chartwell acquisition"), an investment management firm with over 150 institutional clients and approximately $7.5 billion in assets under management. Under the terms of the Asset Purchase Agreement substantially all of the assets of Chartwell Investment Partners, LP were acquired for a purchase price consisting of approximately $45 million paid in cash at closing and an estimated earn-out arrangement of approximately $15 million to be determined based on the growth in EBITDA (earnings before interest, taxes, depreciation and amortization) of Chartwell in 2014. The earn-out will be calculated based on a multiple of six times the increase in Chartwell's annual EBITDA for the year ended December 31, 2014. Any increase to the earn-out calculation above the estimated $15 million recorded at closing, will be expensed in the period in which it is deemed probable to occur. Up to 60 percent of the earn-out may be paid in common stock of the Company at its option. 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 2.1 to the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 3, 2014, the terms of which Agreement are incorporated herein by reference.

The change in the fair values of our municipal bonds and fixed-rate agency mortgage-backed securities are primarily the result of interest rate fluctuations. To assess for impairment on municipal bonds, corporate bonds, single-issuer trust preferred securities, non-agency mortgage-backed securities 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 the securities in an unrealized loss position until recovery of their amortized cost. Based on this, the Company considers all of the unrealized losses to be temporary impairment losses. Within the available-for-sale portfolio, there were 17 positions, aggregating to $775,000 in unrealized losses that were temporarily impaired as of September 30, 2014, of which 10 positions were in an unrealized loss position for more than twelve months totaling $541,000. As of December 31, 2013, there were 35 positions, aggregating to $3.6 million in unrealized losses that were temporarily impaired, of which three positions were in an unrealized loss position for more than twelve months totaling $258,000. Within the held-to-maturity portfolio, there were 9 positions, aggregating to $64,000 in unrealized losses that were temporarily impaired as of September 30, 2014, of which 6 positions were in an unrealized loss position for more than twelve months totaling $25,000. As of December 31, 2013, there were 24 positions, aggregating to $926,000 in unrealized losses that were temporarily impaired.
There were no investment securities classified as trading securities outstanding as of September 30, 2014 and December 31, 2013, respectively.
There was no activity in investment securities classified as trading during the three months ended September 30, 2014. Proceeds from the sale of investment securities trading, comprised of U.S. Treasury Notes, during the three months ended September 30, 2013, were $28.3 million. Income on investment securities trading during the three months ended September 30, 2013, was $4,000.
There was no activity in investment securities classified as trading during the nine months ended September 30, 2014. Proceeds from the sale of investment securities trading, comprised of U.S. Treasury Notes, during the nine months ended September 30, 2013, were $77.4 million. Income on investment securities trading during the nine months ended September 30, 2013, was $120,000.

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. 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.
	Loans receivable by channel is comprised of the following:

	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 September 30, 2014 and December 31, 2013, was $911.9 million and $662.8 million, 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 September 30, 2014, are as follows: $516.2 million in one year or less; $215.8 million in one to three years; and $179.8 million in greater than three years. The reserve for losses on unfunded commitments was $631,000 and $465,000, as of September 30, 2014 and December 31, 2013, respectively, which includes reserves for probable losses on unfunded loan commitments, including standby letters of credit, and also risk participations.
	On March 14, 2014, we entered into a loan purchase agreement to acquire $219.7 million (including fees and interest receivable) of loans secured by cash and marketable securities that are included in our private banking channel loan portfolio. This transaction closed on April 11, 2014.
	As of September 30, 2014 and December 31, 2013, the Company had loans in the process of origination totaling approximately $39.3 million and $11.6 million, respectively, which extend over varying periods of time with the majority being disbursed within a 30 to 60 day period.
	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 unfunded commitments amount related to standby letters of credit as of September 30, 2014, included in the total listed above, is $89.7 million of which a portion is collateralized. Should the Company be obligated to perform under the standby letters of credit the Company will seek recourse from the customer for reimbursement of amounts paid. As of September 30, 2014, $21.3 million (in the aggregate) 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 nine months ended September 30, 2014, there was one draw on standby letters of credit for $100,000. 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 is 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 is included in the reserve for losses on unfunded commitments.

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 charged 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. 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, commercial and industrial, commercial real estate and private banking. 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:
	Middle-Market Banking - Commercial and Industrial Loans. This loan portfolio includes primarily 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, except for certain commercial loans that are secured by cash and marketable securities.
	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 often do 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, syndicated loans which also involve a private equity sponsor are combined as a homogeneous group and evaluated based on the historical 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 as well as global cash flows from the developer are the primary sources of repayment for these loans. Also included are commercial construction loans, which are loans made 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 condition of the local/regional economy, whether or not the project is owner occupied, and the type of project and the experience and resources of the developer.
	Private Banking Channel Loans. Our private banking lending activities are conducted on a national basis. This loan portfolio includes primarily loans made to high-net-worth individuals and/or trusts and businesses that may be secured by cash, marketable securities, residential property or other financial assets, as well as unsecured loans and lines of credit. 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. In addition, the condition of the local economy and the local housing market can also have a significant impact on this portfolio, since low demand and/or declining home values can limit the ability of borrowers to sell a property and satisfy the debt.
	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. The Company’s internal risk rating system is consistent with definitions found in current regulatory guidelines.
	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. 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. 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:
	Non-Rated – Loans to individuals and trusts are not individually risk rated, unless they are fully secured by liquid assets or cash, or have an exposure of $250,000 or greater and have certain actionable covenants, such as a liquidity covenant or a financial reporting covenant. In addition, commercial loans with an exposure of less than $500,000 are not required to be individually risk rated. Any loan, regardless of size, is risk rated if it is secured by marketable securities or if it becomes a criticized loan. The majority of the private banking loans that are not risk rated are residential mortgages and home equity loans. We monitor the performance of non-rated loans through ongoing reviews of payment delinquencies. These loans comprised 4.7% and 7.0% of the total loan portfolio, as of September 30, 2014 and December 31, 2013, respectively. For loans that are not risk-rated, the most important indicators of risk are the existence of collateral, the type of collateral and for consumer real estate loans, whether the Bank has a first or second lien position.
	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.

Non-Performing and Impaired Loans
Management monitors the delinquency status of the loan portfolio on a monthly basis. Loans are considered non-performing when interest and principal are 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.

Impaired loans as of September 30, 2014 and December 31, 2013, were $27.4 million and $20.8 million, respectively. There was no interest income recognized on these loans for the nine months ended September 30, 2014, and the twelve months ended December 31, 2013, while these loans were on non-accrual status. As of September 30, 2014 and December 31, 2013, there were no loans 90 days or more past due and still accruing interest income.
Impaired loans were evaluated using the fair value of the collateral as the measurement method or an evaluation of estimated losses, based on a discounted cash flow method, for non-collateral dependent loans. Based on those evaluations, as of September 30, 2014, there were specific reserves totaling $7.0 million, which is included in the $22.4 million allowance for loan losses. Also included in impaired loans are two C&I loans, two CRE loans and three private banking loans with a combined balance of $5.8 million as of September 30, 2014, with no corresponding specific reserve since these loans were written down to the level which management believes will be recovered from the borrower.
As of December 31, 2013, there was a specific reserve established totaling $5.5 million, which is included in the $19.0 million allowance for loan losses. Also included in impaired loans are two C&I loans, two CRE loans and two private banking loans with a combined balance of $4.8 million as of December 31, 2013, with no corresponding specific reserve since these loans were written down to the level which management believes will be recovered from the borrower.

Total troubled debt restructurings	$	15,999		$	13,548
Of the non-accrual loans as of September 30, 2014, four C&I loans, one CRE loan and two residential mortgage loans were designated by the Company as TDRs. There was also one C&I loan that was still accruing interest and designated by the Company as a performing TDR as of September 30, 2014. The aggregate recorded investment of these loans was $16.0 million. There were $605,000 of unused commitments on non-accrual TDRs as of September 30, 2014, and there was $54,000 of unused commitments on the one accruing TDR.
Of the non-accrual loans as of December 31, 2013, four C&I loans, one CRE loan and one residential mortgage loan were designated by the Company as TDRs. There was also one C&I loan that was still accruing interest and designated by the Company as a performing TDR as of December 31, 2013. The aggregate net carrying value of these loans was $13.5 million. There was $820,000 of unused commitments on these loans as of December 31, 2013, of which $149,000 was related to an accruing TDR.
The modifications made to restructured loans typically consist of an extension or reduction of the payment terms, or the deferral of principal payments. We generally do not forgive principal when restructuring loans. There were no payment defaults, during the three and nine months ended September 30, 2014 and 2013, for loans modified as TDRs within twelve months of the corresponding balance sheet dates.
There were no new loans designated as TDRs during the three months ended September 30, 2014 and 2013.
The financial effects of modifications made to loans designated as TDRs during the nine months ended September 30, 2014 and 2013, are as follows:

The proceeds qualify as Tier 2 capital for the holding company, under federal regulatory capital rules. The proceeds will help fund continued growth and ensure that the company and its bank subsidiary maintain their adequate and well capitalized positions, respectively, and may be used to invest in the Bank and Chartwell, and for other general corporate purposes.
	During the second quarter the Bank increased FHLB borrowings to fund loan growth, specifically the $219.7 million of acquired loans. Refer to Note 4, for more information on the acquired loans.
	The Bank has borrowing capacity with the FHLB. The borrowing capacity is based on the collateral value of certain securities held in safekeeping at the FHLB and loans pledged to the FHLB. The Bank submits a quarterly Qualified Collateral Report (“QCR”) to the FHLB to update the value of the loans pledged. As of September 30, 2014, the Bank’s borrowing capacity is based on the information provided in the June 30, 2014, QCR filing. As of September 30, 2014, the Bank had securities held in safekeeping at the FHLB with a fair value of $8.7 million, combined with pledged loans of $598.6 million, for a total borrowing capacity of $297.1 million, net of $130.0 million outstanding in advances from the FHLB as reflected in the table above. As of December 31, 2013, there was $20.0 million outstanding in advances from the FHLB, which was repaid in 2014. When the Bank borrows from the FHLB, interest is charged at the FHLB's posted rates at the time of the borrowing.
	The Bank maintains an unsecured line of credit of $10.0 million with M&T Bank and an unsecured line of credit of $20.0 million with Texas Capital Bank. As of September 30, 2014, the full amount of these established lines were available to the Bank.

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 Tier 1 and Total risk-based capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). As of September 30, 2014, TriState Capital Holdings, Inc. and TriState Capital Bank exceeded all capital adequacy requirements to which they are subject.
	Financial depository institutions are categorized as Well Capitalized if they meet minimum Total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios (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.
	The following tables set forth certain information concerning the Company’s and the Bank’s regulatory capital as of September 30, 2014 and December 31, 2013:

DERIVATIVE 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. The Company also has derivatives that are a result of a service the Company provides to certain qualifying customers. The Company manages a matched book with respect to its derivative instruments offered as a part of this service to its customers in order to minimize its net risk exposure resulting from such transactions.
	FAIR VALUES OF DERIVATIVE INSTRUMENTS ON THE STATEMENTS OF FINANCIAL CONDITION
	The tables below present the fair value of the Company’s derivative financial instruments as well as their classification on the consolidated statements of financial condition as of September 30, 2014 and December 31, 2013:

	Interest rate products	Other assets	$	—			Other liabilities	$	736
	Derivatives not designated as hedging instruments:
	Interest rate products	Other assets	$	3,417			Other liabilities	$	3,515
	FAIR VALUE HEDGES OF INTEREST RATE RISK
	The Company is exposed to changes in the fair value of certain of its fixed-rate obligations due to changes in benchmark interest rates, which relate predominantly to LIBOR. Interest rate swaps designated as fair value hedges involve the receipt of variable rate payments from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. As of September 30, 2014, the Company had five interest rate swaps, with a notional amount of $7.6 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 is considered insignificant for nine months ended September 30, 2014 and 2013. There were no counterparty default losses on derivatives for the nine months ended September 30, 2014 and 2013.
	For the five derivatives that are 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 three and nine months ended September 30, 2014, the Company recognized gains of $2,000 and $6,000 in non-interest income related to hedge ineffectiveness. The Company also recognized a decrease to interest income of $80,000 and $247,000 for the three and nine months ended September 30, 2014, 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.
	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 economically hedged by offsetting derivatives that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings. As of September 30, 2014, the Company had 100 derivative transactions with an aggregate notional amount of $348.4 million related to this program. During the three and nine months ended September 30, 2014, the Company recognized a net gain of $19,000 and net loss of $195,000, respectively, related to changes in fair value of the derivatives not designated in hedging relationships.

	DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
	Fair value estimates of financial instruments are based on the present value of expected future cash flows, quoted market prices of similar financial instruments, if available, and other valuation techniques. These valuations are significantly affected by discount rates, cash flow assumptions, and risk assumptions used. Therefore, fair value estimates may not be substantiated by comparison to independent markets and are not intended to reflect the proceeds that may be realized in an immediate settlement of instruments. Accordingly, the aggregate fair value amounts presented below do not represent the underlying value of the Company.
	FAIR VALUE MEASUREMENTS
	In accordance with U.S. GAAP the Company must account for certain financial assets and liabilities at fair value on a recurring and non-recurring basis. The Company utilizes a three-level fair value hierarchy of valuation techniques to estimate the fair value of its financial assets and liabilities based on whether the inputs to those valuation techniques are observable or unobservable. The fair value hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within multiple levels of the fair value hierarchy, the lowest level input that has a significant impact on fair value measurement is used.
	Financial assets and liabilities are categorized based upon the following characteristics or inputs to the valuation techniques:
	•	Level 1 – Financial assets and liabilities for which inputs are observable and are obtained from reliable quoted prices for identical assets or liabilities in actively traded markets. This is the most reliable fair value measurement and includes, for example, active exchange-traded equity securities.
	•	Level 2 – Financial assets and liabilities for which values are based on quoted prices in markets that are not active or for which values are based on similar assets or liabilities that are actively traded. Level 2 also includes pricing models in which the inputs are corroborated by market data, for example, matrix pricing.
	•	Level 3 – Financial assets and liabilities for which values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Level 3 inputs include assumptions of a source independent of the reporting entity or the reporting entity’s own assumptions that are supported by little or no market activity or observable inputs.
	The Company is responsible for the valuation process and as part of this process may use data from outside sources in establishing fair value. The Company performs due diligence to understand the inputs used or how the data was calculated or derived. The Company corroborates the reasonableness of external inputs in the valuation process.
	RECURRING FAIR VALUE MEASUREMENTS
	The following tables represent assets and liabilities measured at fair value on a recurring basis as of September 30, 2014 and December 31, 2013:

	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, municipal bonds, non-agency mortgage-backed securities, collateralized mortgage obligations and mortgage-backed securities issued by U.S. government agencies and U.S. government agency debentures.
	INTEREST RATE SWAPS
	The fair value is estimated using inputs that are observable or that can be corroborated by observable market data and, therefore, are classified as Level 2. These fair value estimations include primarily market observable inputs such as the forward LIBOR swap curve.
	NON-RECURRING FAIR VALUE MEASUREMENTS
	Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment.
	The following tables represent the balances of assets measured at fair value on a non-recurring basis as of September 30, 2014 and December 31, 2013:
		30-Sep-14

As of September 30, 2014, the Company recorded $7.0 million of specific reserves to the allowance for loan losses as a result of adjusting the fair value of the collateral for certain collateral dependent impaired loans to $6.1 million, and as a result of adjusting the value based upon the discounted cash flow to $14.4 million as of September 30, 2014.
As of December 31, 2013, the Company recorded $5.5 million of specific reserves to allowance for loan losses as a result of adjusting the fair value of the collateral for certain collateral dependent impaired loans to $8.2 million, and as a result of adjusting the value based upon the discounted cash flow to $7.1 million as of December 31, 2013.
The Company obtains updated appraisals for collateral dependent impaired loans on an annual basis, unless circumstances require a more frequent appraisal.
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 the fair value of the underlying collateral or discounted cash flows when collateral does not exist. 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 which may 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 for which it has established specific reserves as part of the allocated allowance component 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 the lower of the related original loan balance or fair value, less estimated disposition costs, with the fair value being determined by appraisal. Subsequently, foreclosed assets are valued at the lower of the amount recorded at acquisition date or fair value, less estimated disposition costs. 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 September 30, 2014 and December 31, 2013:

The following methods and assumptions were used to estimate the fair value of each class of financial instruments as of September 30, 2014 and December 31, 2013:
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.
LOANS HELD-FOR-INVESTMENT
The fair value of loans 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.
FEDERAL HOME LOAN BANK STOCK
The carrying value of our FHLB stock, which is a marketable equity investment, approximates fair value.
BANK OWNED LIFE INSURANCE
The Company owns general account bank owned life insurance. The fair value of the general account BOLI is based on the insurance contract net cash surrender value.
OTHER REAL ESTATE OWNED
Real estate owned is recorded on the date acquired at the lower of the related original loan balance or fair value, less estimated disposition costs, with the fair value being determined by appraisal. Subsequently, foreclosed assets are valued at the lower of the amount recorded at acquisition date or fair value, less estimated disposition costs.
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 certificates of deposit 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 our borrowings is calculated by discounting scheduled cash flows through the estimated maturity using period end market rates for borrowings of similar remaining maturities.
INTEREST RATE SWAPS
The fair value of interest rate swaps are estimated through the assistance of an independent third party and compared to the fair value determined by the swap counterparty to establish reasonableness.
OFF-BALANCE SHEET INSTRUMENTS
Fair values for the Company’s off-balance sheet instruments, which consist of lending commitments, standby letters of credit and risk participation agreements related to interest rate swap agreements, are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. Management believes that the fair value of these off-balance sheet instruments is not significant.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2014
Accounting Policies [Abstract]	'
Use of Estimates	'
	USE OF ESTIMATES
	The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States of America requires management to make estimates and assumptions that affect the reported amounts of certain assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of related revenue and expense during the reporting period. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be 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, goodwill, evaluation of goodwill 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 (since the acquisition on March 5, 2014) and CTSC Securities (since its initial capitalization in May 2014), after elimination of inter-company accounts and transactions. The accounts of the Bank, in turn, include its wholly-owned subsidiary, Meadowood Asset Management, LLC, after elimination of inter-company accounts and transactions. The unaudited consolidated financial statements of the Company presented herein have been prepared pursuant to rules of the Securities and Exchange Commission for quarterly reports on form 10-Q and do not include all of the information and note disclosures required by GAAP for a full year presentation. In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures, considered necessary for the fair presentation of the accompanying consolidated financial statements, have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2013, included in the Company's Annual Report on Form 10-K.
Business Combinations	'
	BUSINESS COMBINATIONS
	We account 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.
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 which 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 changes in fair value reported as a component of accumulated other comprehensive income (loss).
	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 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. Impaired debt securities are determined to be other-than-temporarily impaired (“OTTI”) if the Company concludes as of the balance sheet date that it has the intent to sell, or believes it will more likely than not be required to sell, an impaired debt security before a recovery of its amortized cost basis. Credit losses on OTTI debt securities are recorded through earnings, regardless of the intent or the requirement to sell. Credit loss is measured as the difference between the present value of an impaired debt security’s expected cash flows and its amortized cost basis. Non-credit related OTTI charges are recorded as decreases to accumulated other comprehensive income (loss), in the consolidated statement of comprehensive income as well as the shareholders’ equity section of the consolidated statement of financial condition, on an after-tax basis, as long as the Company has no intent or expected requirement to sell the impaired debt security before a recovery of its amortized cost basis.
Loans	'
	LOANS
	Loans and leases are stated at unpaid principal balances, net of deferred loan fees and costs. 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 modified 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.
	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 unpaid accrued 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 and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the total 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, other than bank premises, is recorded at the lower of the related original loan balance or fair value less estimated selling costs at the time of acquisition. Fair value is determined based on an independent appraisal. Expenses related to holding the property are charged against earnings in the current period. 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 charged to operations. Loans are charged 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 is appropriate, in management's judgment, to cover probable losses inherent in the loan portfolio as of September 30, 2014 and December 31, 2013. 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 future cash flows 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-off rates 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. 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 channels. As the loan loss history, mix, and risk rating 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 may impact 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 which drives the secondary factor. There are nine (9) 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. The impact of each risk factor 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.
	Loan participations follow the same underwriting and risk rating criteria, and are individually risk rated under the same process as loans directly originated by the Company. The ongoing credit review of participation loans follows the same process that is followed by loans originated directly by the Company. Additionally, management does not rely solely on information from the lead bank when considering the appropriate level of allowance for loan losses to be recorded on any individual participation loan.
	The Company also maintains a reserve for losses on unfunded commitments. This reserve is reflected as a component of other liabilities and, in management’s judgment, is sufficient to cover probable losses inherent in the commitments. Management tracks the level and trends in unused commitments and takes into consideration the same factors as those considered for purposes of the allowance for loan losses on outstanding loans.
Investment Management Fees	'
	INVESTMENT MANAGEMENT FEES
	The Company recognizes investment management fee revenue when the advisory services are performed. Fees are based on assets under management and are calculated pursuant to individual client contracts. Investment management fees are generally paid on a quarterly basis. In a limited number of cases, the Company may earn a performance fee based on investment performance achieved versus a stated benchmark. In such cases, performance fees are not recognized until the end of the stated measurement period. Performance fees are included in investment management fee revenue in the consolidated statements of income.
	Investment management fees receivable represent amounts due from contractual investment advisory 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 nine months ended September 30, 2014, and there was no allowance for uncollectible accounts recorded as of September 30, 2014.
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. Cash and stock dividends are reported as income from investment securities, 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. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. Other intangible assets that have finite lives, such as trade name, client relationships and non-compete agreements are amortized over their estimated useful lives and subject to periodic impairment testing. Other intangible assets are amortized on a straight-line basis over their estimated useful lives which range from four to twenty years. Goodwill is subject to impairment testing at the reporting unit level, which is conducted at least annually.
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 which 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 executive 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 or expense in the consolidated statements of income.
Deposits	'
	DEPOSITS
	Deposits are stated at principal outstanding and interest on deposits is accrued and charged to 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. Interest expense is recognized based on the coupon rate of the obligations. Costs associated with the acquisition of subordinated notes payable are amortized over the expected term of the borrowing.
Earnings Per Share	'
	EARNINGS PER COMMON SHARE
	We compute earnings per common share (“EPS”) in accordance with the two-class method, which requires that any Series C convertible preferred stock outstanding be treated as participating securities in the computation of EPS. The two-class method is an earnings allocation that determines EPS for each class of common stock and participating security. The Company’s basic EPS is computed by dividing net income allocable to common shareholders by the weighted average number of its common shares outstanding for the period. The Company’s diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings.
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 statement of income.
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 stock, made to employees and directors.
	The Company accounts for stock-based employee compensation in accordance with the fair value recognition provisions of ASC 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 718. The value of the portion of the award that is ultimately expected to vest is included in stock-based employee compensation cost in the consolidated statement of income and recorded as a component of Additional Paid-In Capital, for equity-based awards. Compensation expense for options with graded vesting schedules is recognized on a straight-line basis over the requisite service period for the entire option 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.
Recent Accounting Developments	'
	RECENT ACCOUNTING DEVELOPMENTS
	In August 2014, the FASB issued Accounting Standards Update ("ASU") No. 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 first annual period ending after December 15, 2016, and for annual and interim periods thereafter. Early application is permitted. The adoption of ASU 2014-15 is not expected to have a material impact on the Company’s consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-14, "Receivables - Troubled Debt Restructuring by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure." This ASU will require creditors to derecognize certain foreclosed government-guaranteed mortgage loans and to recognize a separate other receivable that is measured at the amount the creditor expects to recover from the guarantor, and to treat the guarantee and the receivable as a single unit of account. This update is effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. An entity can elect a prospective or a modified retrospective transition method, but must use the same transition method that it elected under FASB ASU No. 2014-04, "Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure." Early adoption, including adoption in an interim period, is permitted if the entity already adopted ASU 2014-04. The adoption of ASU 2014-14 is not expected to have a material impact on the Company’s consolidated financial statements.
	In June 2014, the FASB issued ASU No. 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 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015, for all entities. Early adoption is permitted. 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 is not expected to have a material impact on the Company’s consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-04, "Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure." This ASU clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2014 and December 15, 2015, for public and nonpublic entities, respectively. Early adoption and retrospective application are permitted. The adoption of ASU 2014-04 is not expected to have a material impact on the Company’s consolidated financial statements.
