Accounting Policies [Abstract]
BASIS OF INFORMATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BASIS OF INFORMATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES NATURE OF OPERATION TriState Capital Holdings, Inc. ( “we,” “us,” “our,” the “holding company,” the “parent company,” or the “Company”) is a registered bank holding company pursuant to the Bank Holding Company Act of 1956, as amended. The Company has three wholly owned subsidiaries: TriState Capital Bank, a Pennsylvania-chartered state bank (the “Bank”); Chartwell Investment Partners, LLC, a registered investment adviser (“Chartwell”); and Chartwell TSC Securities Corp., a registered broker-dealer (“CTSC Securities”). The Bank was established to serve the commercial banking needs of middle-market businesses and financial services providers and focused private banking needs of high-net-worth individuals nation-wide. The Bank has two wholly owned subsidiaries: TSC Equipment Finance LLC (“TSC Equipment Finance”), established to hold and manage loans and leases of our equipment finance business, and Meadowood Asset Management, LLC (“Meadowood”), established to hold and manage other real estate owned by the Bank and/or foreclosed properties for the Bank. Chartwell provides investment management services primarily to institutional investors, mutual funds and individual investors. CTSC Securities supports marketing efforts for the proprietary investment products provided by Chartwell, including shares of mutual funds advised and/or administered by Chartwell. The Company and the Bank are subject to regulatory examination and supervision by the Federal Deposit Insurance Corporation (“FDIC”), the Pennsylvania Department of Banking and Securities and the Board of Governors of the Federal Reserve System (“Federal Reserve”). In addition, if the Bank’s consolidated total assets exceed $10 billion for four consecutive quarters, the Company and the Bank will become subject to the regulatory examination and supervision of the Consumer Financial Protection Bureau (“CFPB”) with respect to certain consumer protection laws. The Bank’s quarter-end consolidated assets exceeded $10 billion for three consecutive quarters as of September 30, 2021. Chartwell is a registered investment adviser regulated by the U.S. Securities and Exchange Commission (“SEC”). CTSC Securities is regulated by the SEC and the Financial Industry Regulatory Authority, Inc. (“FINRA”). The Bank conducts business through its main office located in Pittsburgh, Pennsylvania, as well as its four additional representative offices in Cleveland, Ohio; Philadelphia, Pennsylvania; Edison, New Jersey; and New York, New York. Chartwell conducts business through its office located in Berwyn, Pennsylvania, and CTSC Securities conducts business through its office located in Pittsburgh, Pennsylvania. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States of America requires management to make estimates and assumptions that affect the reported amounts of certain assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of related revenues and expenses during the reporting period. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be different than those anticipated in the estimates, which could materially affect the financial results of our operations and financial condition. Material estimates that are particularly susceptible to significant changes relate to the determination of the allowance for credit losses on loans and leases, valuation of goodwill and other intangible assets and their evaluation for impairment, fair value measurements and deferred income taxes and their related recoverability, each of which is discussed later in this section. CONSOLIDATION Our consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, the Bank, Chartwell and CTSC Securities, after elimination of inter-company accounts and transactions. The accounts of the Bank, in turn, include its wholly owned subsidiaries, TSC Equipment Finance and Meadowood, after elimination of inter-company accounts and transactions. The unaudited condensed consolidated financial statements of the Company presented herein have been prepared pursuant to SEC rules 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 unaudited condensed consolidated financial statements have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company and the related notes for the fiscal year ended December 31, 2020, included in the Company’s Annual Report on Form 10-K filed with the SEC on February 25, 2021. CASH AND CASH EQUIVALENTS For purposes of reporting cash flows, the Company has defined cash and cash equivalents as cash, interest-earning deposits with other institutions, federal funds sold and short-term investments that have an original maturity of 90 days or less. Under agreements with certain of its derivative counterparties, the Company is required to maintain minimum cash collateral posting thresholds with such counterparties. The cash subject to these agreements is considered restricted for these purposes. BUSINESS COMBINATIONS The Company accounts for business combinations using the acquisition method of accounting. Under this method of accounting, the acquired company’s net assets are recorded at fair value as of the date of acquisition, and the results of operations of the acquired company are combined with our results from that date forward. Acquisition costs are expensed when incurred. The difference between the purchase price, which includes an initial measurement of any contingent earn out, and the fair value of the net assets acquired (including identified intangibles) is recorded as goodwill in the consolidated statements of financial condition. A change in the initial estimate of any contingent earn out amount is recorded to non-interest expense in the consolidated statements of income. INVESTMENT SECURITIES The Company’s investments are classified as either: (1) held-to-maturity, which are debt securities that the Company intends to hold until maturity and are reported at amortized cost, net of allowance for credit losses; (2) trading, which are debt 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 non-interest income; (3) available-for-sale, which are debt securities not classified as either held-to-maturity or trading securities and reported at fair value, with unrealized gains and losses reported as a component of accumulated other comprehensive income (loss), on an after-tax basis; or (4) equity securities, which are reported at fair value, with unrealized gains and losses included in non-interest income. The cost of securities sold is determined on a specific identification basis. Amortization of premiums and accretion of discounts are recorded to interest income on investments over the estimated life of the security utilizing the level yield method. Management evaluates expected credit losses on held-to-maturity debt securities on a collective or pool basis, by investment category and credit rating. The Company measures credit losses by comparing the present value of cash flows expected to be collected to the amortized cost of the security that considers historical credit loss information, adjusted for current conditions and reasonable and supportable economic forecasts. The Company’s investment securities can be classified into the following pools based on similar risk characteristics: (1) U.S. government agencies, (2) state and local municipalities, (3) domestic corporations, including trust preferred securities, and (4) non-agency securitizations. The Company’s U.S. government agency securities are issued by U.S. government entities and agencies and are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. For the remaining pools of securities, the credit rating of the issuers, the investment’s cash flow characteristics and the underlying instruments securitizing certain bonds are the most relevant risk characteristics of the investment portfolio. The Company’s investment policy only allows for purchases of investments with investment grade credit ratings and the Company continuously monitors for changes in credit ratings. Probability of default and loss given default rates are based on historical averages for each investment pool, adjusted to reflect the impact of a single, forward-looking forecast of certain macroeconomic variables, such as unemployment rates and interest rate spreads, which management considers to be both reasonable and supportable. The forecast of these macroeconomic variables is applied over a period of three years and reverts to historical averages over a two-year reversion period. Management evaluates available-for-sale debt securities in an unrealized loss position quarterly for expected credit losses. Management first determines whether it intends to sell or if it is more likely than not that it will be required to sell the impaired securities. This determination considers current and forecasted liquidity requirements, regulatory and capital requirements, and securities portfolio management. If the Company intends to sell an available-for-sale security with a fair value below amortized cost or if it is more likely than not that it will be required to sell such a security before recovery, the security’s amortized cost is written down to fair value through current period earnings. For available-for-sale debt securities that the Company does not intend to sell or it is more likely than not that it will not be required to sell before recovery, a provision for credit losses is recorded through current period earnings for the amount of the valuation decline below amortized cost that is attributable to credit losses. Management considers the extent to which fair value is less than amortized cost, credit ratings and other factors related to the security in assessing whether credit loss exists. The Company measures credit loss by comparing the present value of cash flows expected to be collected to the amortized cost of the security. An allowance for credit losses is measured by the difference that the present value of cash flows expected to be collected is less than the amortized cost, limited by the amount that the fair value is less than the amortized cost. The remaining difference between the security’s fair value and amortized cost (that is, the decline in fair value not attributable to credit losses) is recognized in other comprehensive income (loss), in the consolidated statements of comprehensive income and the shareholders’ equity section of the consolidated statements of financial condition, on an after-tax basis. Changes in the allowance for credit losses are recorded as provision for credit losses. Losses are charged against the allowance when management believes the security is uncollectible or management intends to sell or is required to sell the security. The recognition of interest income on a debt security is discontinued when any principal or interest payment becomes 90 days past due, at which time the debt security is placed on non-accrual status. All accrued and unpaid interest on such debt security is then reversed. Accrued interest receivable is excluded from the estimate of expected credit losses. FEDERAL HOME LOAN BANK STOCK The Bank is a member of the Federal Home Loan Bank (“FHLB”) of Pittsburgh. Member institutions are required to invest in FHLB stock. The stock is carried at cost, which approximates its liquidation value, and it is evaluated for impairment based on the ultimate recoverability of the par value. The following matters are considered by management when evaluating the FHLB stock for impairment: the ability of the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; the impact of legislative and regulatory changes on the institution and its customer base; and the Company’s intent and ability to hold its FHLB stock for the foreseeable future. Management believes the Company’s holdings in the FHLB stock were recoverable at par value as of September 30, 2021 and December 31, 2020. Cash and stock dividends are reported as interest income on investments in the consolidated statements of income. LOANS AND LEASES Loans and leases held-for-investment are stated at amortized cost. Amortized cost is the unpaid principal balance, net of deferred loan fees and costs. Loans held-for-sale are stated at the lower of cost or fair value. Interest income on loans is accrued at the contractual rate on the principal amount outstanding. Deferred loan fees and costs are amortized to interest income over the estimated life of the loan, taking into consideration scheduled payments and prepayments. The Company considers a loan to be a troubled debt restructuring (“TDR”) when there is a concession made to a financially troubled borrower without adequate consideration provided to the Company. The Company evaluates any loan reasonably expected to become a TDR, regardless of whether the loan is on accrual or non-accrual status. Once a loan is deemed to be a TDR, the Company considers whether the loan should be placed on non-accrual status. In assessing accrual status, the Company considers the likelihood that repayment and performance according to the original contractual terms will be achieved, as well as the borrower’s historical payment performance. A loan is designated and reported as a TDR until such loan is either paid off or sold unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is fully expected that the remaining principal and interest will be collected according to the restructured agreement. The recognition of interest income on a loan is discontinued when, in management’s opinion, it is probable the borrower is unable to meet payments as they become due or when the loan becomes 90 days past due, whichever occurs first, at which time the loan is placed on non-accrual status. All accrued and unpaid interest on such loans is then reversed. The 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 The Company is a party to financial instruments with off-balance sheet risk, such as 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 lending agreement with such customer. Commitments generally have fixed expiration dates or other termination clauses (e.g., loans due on demand) and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the unfunded commitment amount does not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis using the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The amount of collateral obtained, if deemed necessary by the Company upon extension of a commitment, is based on management’s credit evaluation of the borrower. OTHER REAL ESTATE OWNED Real estate owned, other than bank premises, is recorded at fair value less estimated selling costs. Fair value is determined based on an independent appraisal. Expenses related to holding the property are charged against earnings when incurred. Depreciation is not recorded on other real estate owned (“OREO”) properties. ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASES The allowance for credit losses is a valuation account that is deducted from the amortized cost of loans and leases to present management’s best estimate of the net amount expected to be collected. Adjustments to the allowance for credit losses are established through provisions for credit losses that are recorded in the consolidated statements of income. Loans and leases are charged off against the allowance for credit losses when management believes that the principal is uncollectible. If, at a later time, amounts are recovered with respect to loans and leases previously charged off, the recovered amount is credited to allowance for credit losses. Accrued interest receivable is excluded from the estimate of expected credit losses. The allowance for credit losses represents estimates of expected credit losses for homogeneous loan pools that share similar risk characteristics such as commercial and industrial (“C&I”) loans and leases, commercial real estate (“CRE”) loans, and private banking loans, which include consumer lines of credit and residential mortgages. The Company periodically reassesses each loan pool to ensure that the loans within the pool continue to share similar risk characteristics. Non-accrual loans and loans designated as TDRs are assessed individually using a discounted cash flow method or, where a loan is collateral dependent, based upon the fair value of the collateral less estimated selling costs. The collateral on our private banking loans that are secured by cash, marketable securities and/or cash value life insurance is monitored daily and requires borrowers to continually replenish such collateral as a result of changes in its fair value. Therefore, it is expected that the fair value of the collateral securing each loan will exceed the loan’s amortized cost and no allowance for credit losses would be required under Accounting Standard Codification (“ASC”) 326-20-35-6, “Financial Assets Secured by Collateral Maintenance Provisions.” In estimating the general allowance for credit losses for loans evaluated on a collective or pool basis, management considers past events, current conditions, and reasonable and supportable economic forecasts, including historical charge-offs and subsequent recoveries. Management also considers qualitative factors that influence our credit quality, including, but not limited to, delinquency and non-performing loan trends, changes in loan underwriting guidelines and credit policies, and the results of internal loan reviews. Finally, management considers the impact of changes in current and forecasted local and regional economic conditions in the markets that we serve. Management bases the computation of the general allowance for credit losses 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: C&I loans and leases, CRE loans and private banking loans (other than those secured by cash, marketable securities and/or cash value life insurance). For each portfolio, management estimates expected credit losses over the life of each loan utilizing lifetime or cumulative loss rate methodology, which identifies macroeconomic factors and asset-specific characteristics that are correlated with credit loss experience, including loan age, loan type, leverage, risk rating, interest rate spread and industry. The lifetime loss rate is applied to the amortized cost of the loan. This methodology builds on default and recovery probabilities by utilizing pool-specific historical loss rates to calculate expected credit losses. These pool-specific historical loss rates may be adjusted for a forecast of certain macroeconomic variables, as further discussed below, and other factors such as differences in underwriting standards, portfolio mix, or when historical asset terms do not reflect the contractual terms of the financial assets being evaluated as of the measurement date. Each time the Company measures expected credit losses, the Company assesses the relevancy of historical loss information and considers any necessary adjustments to address any differences in asset-specific characteristics. The allowance for credit losses represents management’s current estimate of expected credit losses in the loan and lease portfolio. Expected credit losses are estimated over the contractual term of the loans, which includes extension or renewal options that are not unconditionally cancellable by the Company and are adjusted for expected prepayments when appropriate. Management’s judgment takes into consideration past events, current conditions and reasonable and supportable economic forecasts including 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 in making such determinations, and that the present allowance for credit losses represents management’s best estimate of current expected credit losses, 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. The lifetime loss rates are estimated by analyzing a combination of internal and external data related to historical performance of each loan pool over a complete economic cycle. Loss rates are based on historical averages for each loan pool, adjusted to reflect the impact of a single, forward-looking forecast of certain macroeconomic variables such as gross domestic product (“GDP”), unemployment rates, corporate bond credit spreads and commercial property values, which management considers to be both reasonable and supportable. The single, forward-looking forecast of these macroeconomic variables is applied over the remaining life of the loan pools. The development of the reasonable and supportable forecast incorporates an assumption that each macroeconomic variable will revert to a long-term expectation starting in years two to four of the forecast and largely completing within the first five years of the forecast. The secondary factor is intended to capture additional risks related to events and circumstances that management believes have an impact on the performance of the loan portfolio that are not considered as part of the primary factor. Although this factor is more subjective in nature, the methodology focuses on internal and external trends in pre-specified categories, or risk factors, and applies a quantitative percentage that drives the secondary factor. Nine risk factors have been identified and each risk factor is assigned an allowance level based on management’s judgment as to the expected impact of each risk factor on each loan portfolio and is monitored on a quarterly basis. As the trend in any risk factor changes, management evaluates the need for a corresponding change to occur in the allowance associated with each respective risk factor to provide the most appropriate estimate of allowance for credit losses on loans and leases. The Company also maintains an allowance for credit losses on off-balance sheet credit exposures for unfunded loan commitments. This allowance is reflected as a component of other liabilities which represents management’s current estimate of expected losses in the unfunded loan commitments. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life based on management’s consideration of past events, current conditions and reasonable and supportable economic forecasts. 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 credit losses on outstanding loans. Unconditionally cancellable loans are excluded from the calculation of allowance for credit losses on off-balance sheet credit exposures. Results for the nine months ended September 30, 2021 are presented under the current expected credit loss (“CECL”) methodology, in accordance with ASC Topic 326, while prior period amounts continue to be reported in accordance with ASC Topic 450, “Contingencies,” and specific reserves based upon ASC Topic 310, “Receivables.” ASC Topic 450 applies to homogeneous loan pools such as commercial loans, consumer lines of credit and residential mortgages that are not individually evaluated for impairment. ASC Topic 310 is applied to commercial and consumer loans that are individually evaluated for impairment. INVESTMENT MANAGEMENT FEES The Company recognizes investment management fee revenue when advisory services are performed. Fees are based on assets under management and are calculated pursuant to individual client contracts. Investment management fees are generally received on a quarterly basis. Certain incremental costs incurred to acquire some of our investment management contracts are deferred and amortized to non-interest expense over the estimated life of the contract. Investment management fees receivable represent amounts due for contractual investment management services provided to the Company’s clients, primarily institutional investors, mutual funds and individual investors. Management performs credit evaluations of its customers’ financial condition when it is deemed to be necessary and does not require collateral. The Company provides an allowance for uncollectible accounts based on specifically identified receivables. The Company has not experienced any losses on receivables for investment management fees for the nine months ended September 30, 2021 and 2020. The Company had no allowance for credit losses on investment management fees as of September 30, 2021 and December 31, 2020. GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill is not amortized and is subject to at least annual assessments for impairment by applying a fair value-based test. The Company reviews goodwill annually and again at any quarter-end if a material event occurs during the quarter that may affect goodwill. If goodwill testing is required, an assessment of qualitative factors can be completed before performing a goodwill impairment test. If an assessment of qualitative factors determines it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, then a goodwill impairment test is not required. Other intangible assets represent purchased assets that may lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. The Company has determined that certain of its acquired mutual fund client relationships meet the criteria to be considered indefinite-lived assets because the Company expects both the renewal of these contracts and the cash flows generated by these assets to continue indefinitely. Accordingly, the Company does not amortize these intangible assets, but instead reviews these assets annually or more frequently whenever events or circumstances occur indicating that the recorded indefinite-lived assets may be impaired. Each reporting period, the Company assesses whether events or circumstances have occurred which indicate that the indefinite life criteria are no longer met. If the indefinite life criteria are no longer met, the Company assesses whether the carrying value of these assets exceeds its fair value. If the carrying value exceeds the fair value of the assets, an impairment loss is recorded in an amount equal to any such excess and the assets are reclassified to finite-lived. Other intangible assets that the Company has determined to have finite lives, such as its trade names, client lists and non-compete agreements are amortized over their estimated useful lives. These finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives, which range from four OFFICE PROPERTIES AND EQUIPMENT Office properties and equipment are stated at cost less accumulated depreciation. Office properties include furniture, fixtures and leasehold improvements. Equipment includes computer equipment and internal use software. Depreciation is computed utilizing 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 OPERATING LEASES The Company is a lessee in noncancellable operating leases, primarily for its office spaces and other office equipment. The Company records operating leases as a right-of-use asset and an offsetting lease liability in the consolidated statements of financial condition at the present value of the unpaid lease payments. The Company generally uses its incremental borrowing rate as the discount rate for operating leases. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the right-of-use asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term. BANK OWNED LIFE INSURANCE Bank owned life insurance (“BOLI”) policies on certain officers and employees are recorded at net cash surrender value on the consolidated statements of financial condition. Upon termination of a BOLI policy, the Company receives the cash surrender value. BOLI benefits are payable to the Company upon the death of the insured. Changes in net cash surrender value are recognized as non-interest income in the consolidated statements of income. DEPOSITS Deposits are stated at principal outstanding. Interest on deposits is accrued and charged to interest expense daily and is paid or credited in accordance with the terms of the respective accounts. BORROWINGS The Company records FHLB advances, line of credit borrowings and subordinated notes payable at their principal amount, net of debt issuance costs. Interest expense is recognized based on the coupon rate of the obligations. Costs associated with the acquisition of subordinated notes payable are amortized to interest expense over the expected term of the borrowing. 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 con

The changes in the fair values of our agency collateralized mortgage obligations and agency mortgage-backed securities are primarily the result of interest rate fluctuations. These agency securities are either explicitly or implicitly guaranteed by the U.S. government, highly rated, and have a long history of no credit losses. To assess for credit losses on debt securities available-for-sale in unrealized loss position, 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. The most recent assessment for credit losses did not identify any issues related to the ultimate repayment of principal and interest on these debt securities. In addition, the Company has the ability and intent to hold debt securities in an unrealized loss position until recovery of their amortized cost. Based on this, no allowance for credit losses has been recognized on debt securities available-for-sale in an unrealized loss position. The Company monitors the credit quality of debt securities held-to-maturity including credit ratings quarterly. The following tables present the amortized costs basis of debt securities held-to-maturity by Moody’s bond credit rating.

The Company had no debt securities held-to-maturity that were past due as of September 30, 2021. There were no outstanding debt securities classified as trading as of September 30, 2021 and December 31, 2020. Equity securities consisted of mutual funds investing in short-duration, investment grade corporate bonds. The investments in these securities were $5.0 million and $0 as of September 30, 2021 and December 31, 2020, respectively. There was $11.8 million and $13.3 million in FHLB stock outstanding as of September 30, 2021 and December 31, 2020, respectively.

LOANS AND LEASES	LOANS AND LEASES The Company generates loans through the private banking and middle-market banking channels. The private banking channel primarily includes loans made to high-net-worth individuals, trusts and businesses that are typically secured by cash, marketable securities and/or cash value life insurance. The middle-market banking channel consists of the Company’s C&I loan and lease portfolio and CRE loan portfolio, which serve middle-market businesses and real estate developers in our primary markets. Loans and leases held-for-investment were comprised of the following: September 30, 2021 (Dollars in thousands) Private Commercial Commercial Total Loans and leases held-for-investment, before deferred fees and costs $ 6,190,874 $ 1,336,331 $ 2,329,762 $ 9,856,967 Net deferred loan costs (fees) 13,135 4,486 (5,577) 12,044 Loans and leases held-for-investment, net of deferred fees and costs 6,204,009 1,340,817 2,324,185 9,869,011 Allowance for credit losses on loans and leases (2,156) (10,796) (19,411) (32,363) Loans and leases held-for-investment, net $ 6,201,853 $ 1,330,021 $ 2,304,774 $ 9,836,648 December 31, 2020 (Dollars in thousands) Private Commercial Commercial Total Loans and leases held-for-investment, before deferred fees and costs $ 4,797,881 $ 1,269,248 $ 2,160,784 $ 8,227,913 Net deferred loan costs (fees) 9,919 4,904 (5,318) 9,505 Loans and leases held-for-investment, net of deferred fees and costs 4,807,800 1,274,152 2,155,466 8,237,418 Allowance for credit losses on loans and leases (2,047) (5,254) (27,329) (34,630) Loans and leases held-for-investment, net $ 4,805,753 $ 1,268,898 $ 2,128,137 $ 8,202,788 The Company’s customers have unused loan commitments based on the availability of eligible collateral or other terms and conditions under their loan agreements . Included in unused loan commitments are unused availability under demand loans for our private banking lines secured by cash, marketable securities and/or cash value life insurance, as well as commitments to fund loans secured by residential properties, commercial real estate, construction loans, business lines of credit and other unused commitments of loans in various stages of funding. Not all commitments will fund or fully fund as customers often only draw on a portion of their available credit. The amount of unfunded commitments, including standby letters of credit, as of September 30, 2021 and December 31, 2020, was $9.45 billion and $6.73 billion, respectively. The interest rate for each commitment is based on the prevailing market conditions at the time of funding. The total unfunded commitments above included loans in the process of origination totaling approximately $93.8 million and $39.6 million as of September 30, 2021 and December 31, 2020, respectively, which extend over varying periods of time. The Company issues standby letters of credit in the normal course of business. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party. The Company would be required to perform under a standby letter of credit when drawn upon by the guaranteed party in the case of non-performance by the Company’s customer. Collateral may be obtained based on management’s credit assessment of the customer. The amount of unfunded commitments related to standby letters of credit as of September 30, 2021 and December 31, 2020, included in the total unfunded commitments above, was $63.1 million and $82.0 million, respectively. Should the Company be obligated to perform under any standby letters of credit, the Company will seek repayment from the customer for amounts paid. During the nine months ended September 30, 2021 and 2020, there were draws on letters of credit totaling $3.5 million and $49,000, respectively, which were repaid by the borrowers. Most of these commitments are expected to expire without being drawn upon and the total amount does not necessarily represent future cash requirements. The allowance for credit losses on off-balance-sheet credit exposures was $3.1 million and $3.4 million as of September 30, 2021 and December 31, 2020, respectively, which includes allowance for credit losses on unfunded loan commitments and standby letters of credit. The Company recorded a credit to provision on off-balance sheet exposures as liabilities of $303,000 and provision expense of $765,000 for the nine months ended September 30, 2021 and 2020, respectively.

Allowance for Credit Losses and Leases [Abstract]
ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASES	ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASES Our allowance for credit losses represents our current estimate of expected credit losses in the portfolio at a specific point in time. This estimate includes credit losses associated with loans and leases evaluated on a collective or pool basis, as well as expected credit losses of the individually evaluated loans and leases that do not share similar risk characteristics. 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, and economic forecasts over a reasonable and supportable period of time. This evaluation is subjective and requires material estimates that may change over time. The calculation of the allowance for credit losses on loans and leases takes into consideration the inherent risk identified within each of the Company’s three primary loan portfolios. The lifetime loss rates are estimated by analyzing a combination of internal and external data related to historical performance of each loan pool over a complete economic cycle. Results for the nine months ended September 30, 2021, are presented under CECL methodology while prior period amounts continue to be reported in accordance with previously applicable GAAP. Refer to Note 1, Summary of Significant Accounting Policies, to our unaudited condensed consolidated financial statements for more details on the Company’s policy on allowance for credit losses on loans and leases. The following discusses key characteristics and risks within each primary loan portfolio: Private Banking Loans Our private banking lending business is conducted on a national basis. This loan portfolio primarily includes loans made to high-net-worth individuals, trusts and businesses that are typically secured by marketable securities, cash, and/or cash value life insurance. The Company actively monitors the value of the collateral securing these loans on a daily basis and requires borrowers to continually replenish such collateral as a result of changes in its fair value. Therefore, it is expected that the fair value of the collateral value securing each loan will exceed the loan’s amortized cost and no allowance for credit loss would be required under ASC 326-20-35-6, “Financial Assets Secured by Collateral Maintenance Provisions.” This portfolio also has some loans that are secured by residential real estate or other financial assets and unsecured loans. The primary sources of repayment for these loans are the income and/or assets of the borrower. The underlying collateral is the most important indicator of risk for this loan portfolio. The overall lower risk profile of this portfolio is driven by loans secured by cash, marketable securities and/or cash value life insurance, which were 98.7% and 98.6% of total private banking loans as of September 30, 2021 and December 31, 2020, respectively. Commercial Banking: Commercial and Industrial Loans and Leases This loan portfolio primarily includes loans and leases made to financial services and other service and/or manufacturing companies generally for the purposes of financing production, operating capacity, accounts receivable, inventory, equipment, acquisitions and/or recapitalizations. Cash flow from the borrower’s operations is the primary source of repayment for these loans and leases; however, most loans are collateralized by commercial assets. The borrower’s industry and local and regional economic conditions are important indicators of risk for this loan portfolio. Collateral for these types of loans at times does not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt. C&I loans collateralized by marketable securities are treated the same as private banking loans for purposes of the calculation of the allowance for credit losses on loans and leases. Commercial Banking: Commercial Real Estate Loans This loan portfolio includes loans secured by commercial purpose real estate, including both owner-occupied properties and investment properties for various purposes including office, industrial, multifamily, retail, hospitality, healthcare and self-storage. The primary source of repayment for CRE loans secured by owner-occupied properties is cash flow from the borrower’s operations. Individual project cash flows, global cash flows and liquidity from the developer, or the sale of the property, are the primary sources of repayment for CRE loans secured by investment properties. Also included in this portfolio are commercial construction loans to finance the construction or renovation of structures as well as to finance the acquisition and development of raw land for various purposes. The increased level of risk for these loans is generally confined to the construction period. If problems arise, 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 and collateral of the loans are important indicators of risk for this loan portfolio. Additional risks exist and are dependent on several factors such as the condition of the local and regional economies, whether or not the project is owner-occupied, the type of project, and the experience and resources of the developer. On a monthly basis, management monitors various credit quality indicators for the loan portfolio, including delinquency, non-performing status, changes in risk ratings, changes in the underlying performance of the borrowers and other relevant factors. On a daily basis, the Company monitors the collateral of loans secured by cash, marketable securities and/or cash value life insurance within the private banking portfolio which further reduces the risk profile of that portfolio. Refer to Note 1, Summary of Significant Accounting Policies, to our unaudited condensed consolidated financial statements for the Company’s policy for determining past due status of loans. Loan risk ratings are assigned based upon the creditworthiness of the borrower and the quality of the collateral for loans secured by marketable securities. Loan risk ratings are reviewed on an ongoing basis according to internal policies and applicable regulatory guidance. Loans within the pass rating are believed to have a lower risk of loss than loans that are risk rated as special mention, substandard or doubtful, which are believed to have an increasing risk of loss. Management also monitors the loan portfolio through a formal periodic review process. All non-pass rated loans are reviewed monthly and higher risk-rated loans within the pass category are reviewed three times a year. The Company’s risk ratings are consistent with regulatory guidance and are as follows: Pass – A pass loan is currently performing in accordance with its contractual terms. Special Mention – A special mention loan has potential weaknesses that warrant management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects or in our credit position at some future date. Economic and market conditions beyond the customer’s control may in the future necessitate this classification. Substandard – A substandard loan is not adequately protected by the net worth and/or paying capacity of the obligor or by the collateral pledged, if any. Substandard loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. These loans are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful – A doubtful loan has all the weaknesses inherent in a loan categorized as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable.

Loans are considered non-performing when interest and principal 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. The following tables present the Company’s amortized cost of individually evaluated loans and related information on those loans as of and for the nine months ended September 30, 2021 and as of and for the twelve months ended December 31, 2020: As of and for the Nine Months Ended September 30, 2021 (Dollars in thousands) Amortized Unpaid Principal Balance Related Allowance Average Recorded Investment Interest Income Recognized With a related allowance recorded: Private banking $ — $ — $ — $ — $ — Commercial and industrial 8,625 8,625 6,900 8,625 — Commercial real estate — — — — — Total with a related allowance recorded 8,625 8,625 6,900 8,625 — Without a related allowance recorded: Private banking — — — — — Commercial and industrial — — — — — Commercial real estate — — — — — Total without a related allowance recorded — — — — — Total: Private banking — — — — — Commercial and industrial 8,625 8,625 6,900 8,625 — Commercial real estate — — — — — Total $ 8,625 $ 8,625 $ 6,900 $ 8,625 $ — As of and for the Twelve Months Ended December 31, 2020 (Dollars in thousands) Amortized Unpaid Principal Balance Related Allowance Average Recorded Investment Interest Income Recognized With a related allowance recorded: Private banking $ — $ — $ — $ — $ — Commercial and industrial 458 457 103 458 — Commercial real estate 9,222 9,251 1,885 9,222 — Total with a related allowance recorded 9,680 9,708 1,988 9,680 — Without a related allowance recorded: Private banking — — — — — Commercial and industrial — — — — — Commercial real estate — — — — — Total without a related allowance recorded — — — — — Total: Private banking — — — — — Commercial and industrial 458 457 103 458 — Commercial real estate 9,222 9,251 1,885 9,222 — Total $ 9,680 $ 9,708 $ 1,988 $ 9,680 $ — Individually evaluated loans were $8.6 million and $9.7 million as of September 30, 2021 and December 31, 2020, respectively. There was no interest income recognized on individually evaluated loans that were also on non-accrual status for the nine months ended September 30, 2021, and the twelve months ended December 31, 2020. As of September 30, 2021 and December 31, 2020, there were no loans 90 days or more past due and still accruing interest income. The Company estimates allowance for credit losses individually for loans that do not share similar risk characteristics, including non-accrual loans and loans designated as TDRs, using a discounted cash flow method or based on the fair value of the collateral less estimated selling costs. Based on those evaluations, there were specific reserves totaling $6.9 million and $2.0 million as of September 30, 2021 and December 31, 2020, respectively. Refer to Note 1, Summary of Significant Accounting Policies, to our unaudited condensed consolidated financial statements for the Company’s policy on evaluating loans for expected credit losses and interest income.

There were no unused commitments on loans designated as TDRs as of September 30, 2021 and December 31, 2020, respectively. The modifications made to restructured loans typically consist of an extension of the payment terms or the deferral of principal payments. There were no loans modified as TDRs within 12 months of the corresponding balance sheet date with payment defaults during the nine months ended September 30, 2021 and 2020. There were no loans newly designated as TDRs during the three months ended September 30, 2021.

The subordinated notes have a term of 10 years at a fixed-to-floating rate of 5.75%. The subordinated notes constitute Tier 2 capital for the Company under federal regulatory capital rules. The Bank’s FHLB borrowing capacity is based on the collateral value of certain securities held in safekeeping at the FHLB, if applicable, and loans pledged to the FHLB. The Bank submits a quarterly Qualifying Collateral Report (“QCR”) to the FHLB to update the value of the loans pledged. As of September 30, 2021, the Bank’s borrowing capacity is based on the information provided in its June 30, 2021 QCR filing. As of September 30, 2021, the Bank had pledged loans of $1.46 billion with the FHLB, for a gross borrowing capacity of $1.04 billion, of which $250.0 million was outstanding in advances. As of December 31, 2020, there was $300.0 million outstanding in advances from the FHLB. 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, 2021 and December 31, 2020, there were no outstanding borrowings under these lines of credit, and they are available to the Bank at the lenders’ discretion.

The clients of the Bank are responsible for repaying any balances due on these credit cards directly to PNC; however, if the customer fails to repay PNC, the Bank could be required to satisfy the obligation to PNC and initiate collection from its customer as part of the existing credit facility of that customer. On August 16, 2021, the Bank entered into a standby letter of credit with PNC Bank for $643,000, which expires on August 16, 2022, for benefit of the lessor of our New York office space in lieu of a security deposit.

STOCK TRANSACTIONS	STOCK TRANSACTIONS On December 30, 2020, the Company completed the private placement of securities pursuant to an Investment Agreement, dated October 10, 2020 and amended December 9, 2020, with T-VIII PubOpps LP (“T-VIII PubOpps”), an affiliate of investment funds managed by Stone Point Capital LLC. Pursuant to the Investment Agreement, the Company sold to T-VIII PubOpps (i) 2,770,083 shares of voting common stock for $40.0 million, (ii) 650 shares of Series C Preferred Stock for $65.0 million, and (iii) warrants to purchase up to 922,438 shares of voting common stock, or non-voting common stock at an exercise price of $17.50 per share. After two years, the Series C Preferred Stock is convertible into shares of non-voting common stock or, when transferred under certain limited circumstances to a holder other than an affiliate of Stone Point Capital LLC, voting common stock, at a price of 13.75 per share. The Series C Preferred Stock has a liquidation preference of $100,000 per share, and pays a quarterly dividend at an annualized rate of 6.75%. The Company received gross proceeds of $105.0 million at closing, and may receive up to an additional $16.1 million if the warrants are exercised in full. The net proceeds were recorded to shareholders’ equity at December 31, 2020, and allocated to the three equity instruments issued using the relative fair value method applied to common stock, preferred stock and the warrants issued, which were recorded to additional paid-in capital. The net proceeds constitute Tier 1 capital for the Company under federal regulatory capital rules. During the nine months ended September 30, 2021 and 2020, the Company paid dividends of $5.9 million on its 6.75% Fixed-to-Floating Rate Series A Non-Cumulative Perpetual Preferred Stock, no par value (the “Series A Preferred Stock”) and its 6.375% Fixed-to-Floating Rate Series B Non-Cumulative Perpetual Preferred Stock, no par value (the “Series B Preferred Stock”). During the nine months ended September 30, 2021, a stock dividend of 22 shares of the Company’s Series C Preferred Stock was paid in kind, as well as cash paid in lieu of a fractional share. Under authorization by the Board of Directors of the Company (“Board”), the Company is permitted to repurchase its common stock up to prescribed amounts, of which $7.3 million remained available as of September 30, 2021. The Board also authorized the Company to utilize some of the share repurchase program authorizations to cancel certain options to purchase shares of its common stock granted by the Company. During the nine months ended September 30, 2021, treasury shares increased 99,946, or approximately $2.0 million, in connection with the net settlement of equity awards exercised or vested. During the nine months ended September 30, 2020, the Company repurchased 40,000 shares of common stock for approximately $670,000, at an average cost of $16.76 per share, which shares are held as treasury stock. In addition to the shares purchased in the market, treasury shares increased 126,148, or approximately $2.7 million, in connection with the net settlement of equity awards exercised or vested during the nine months ended September 30, 2020. Under prior authorization of the Board, stock option cancellation programs were approved to allow for certain outstanding and vested stock option awards to be canceled by the option holder at a price based on the closing day’s stock price less the option exercise price. During the nine months ended September 30, 2020, there were 212,447 options canceled for approximately $2.5 million, which was recorded as a reduction to additional paid-in capital.

Regulatory Capital

Regulatory Capital	9 Months Ended

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
REGULATORY CAPITAL	REGULATORY CAPITAL The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory – and possibly additional discretionary – actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s and the Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the tables below) of Common Equity Tier 1 (“CET 1”) capital, Tier 1 capital and Total capital (each as defined in the regulations) to risk-weighted assets (as defined in the regulations), and of Tier 1 capital to average assets (as defined in the regulations). As of September 30, 2021 and December 31, 2020, TriState Capital Holdings, Inc. and TriState Capital Bank exceeded all capital adequacy requirements to which they were subject. Insured depository institutions are categorized as well capitalized if they meet minimum capital ratios as set forth in the tables below. The Bank exceeded the capital ratios necessary to be well capitalized under the regulatory framework for prompt corrective action. There have been no conditions or events since the filing of the most recent Call Report for the period ending September 30, 2021 that management believes have materially changed the Bank’s capital, as presented in the tables below. A banking organization is also subject to certain limitations on capital distributions and discretionary bonus payments to executive officers if the organization does not maintain the necessary capital conservation buffer of CET 1 capital to risk-weighted assets ratio of 2.5% or more, in addition to the minimum risk-based capital adequacy levels shown in the tables below. Both the Company and the Bank were above the levels required to avoid limitations on capital distributions and discretionary bonus payments. In 2020, U.S. federal regulatory authorities issued a final rule that provides banking organizations that adopt CECL during the 2020 calendar year with the option to delay the impact of CECL on regulatory capital for up to two years, beginning January 1, 2020, followed by a three-year transition period. As the Company adopted CECL on December 31, 2020, the Company elected to utilize the remainder of the two-year delay of CECL’s impact on its regulatory capital, from December 31, 2020 through December 31, 2021, followed by the three-year transition period of CECL impact on regulatory capital, from January 1, 2022 through December 31, 2024.

DERIVATIVES AND HEDGING ACTIVITY	DERIVATIVES AND HEDGING ACTIVITY RISK MANAGEMENT OBJECTIVE OF USING DERIVATIVES The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources, and duration of its debt funding and through the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash payments related to certain of the Company’s FHLB borrowings and to manage the volatility of the change in fair value related to certain of the Company’s equity investments. The Company also has derivatives that are a result of a service the Company provides to certain qualifying customers. When providing this service, the Company generally enters into an offsetting derivative transaction in order to eliminate its interest rate risk exposure resulting from such transactions. FAIR VALUES OF DERIVATIVE INSTRUMENTS ON THE STATEMENTS OF FINANCIAL CONDITION The tables below present the fair value of the Company’s derivative financial instruments as well as their classification on the unaudited condensed consolidated statements of financial condition as of September 30, 2021 and December 31, 2020: Asset Derivatives Liability Derivatives as of September 30, 2021 as of September 30, 2021 (Dollars in thousands) Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives designated as hedging instruments: Interest rate products Other assets $ 276 Other liabilities $ 4,786 Derivatives not designated as hedging instruments: Interest rate products Other assets 100,718 Other liabilities 100,727 Total Other assets $ 100,994 Other liabilities $ 105,513 Asset Derivatives Liability Derivatives as of December 31, 2020 as of December 31, 2020 (Dollars in thousands) Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives designated as hedging instruments: Interest rate products Other assets $ — Other liabilities $ 9,082 Derivatives not designated as hedging instruments: Interest rate products Other assets 144,333 Other liabilities 144,351 Total Other assets $ 144,333 Other liabilities $ 153,433 The following tables show the impact legally enforceable master netting agreements had on the Company’s derivative financial instruments as of September 30, 2021 and December 31, 2020: Offsetting of Derivative Assets Gross Amounts of Recognized Assets Gross Amounts Offset in the Statement of Financial Position Net Amounts of Assets Gross Amounts Not Offset in the Statement of Financial Position Net Amount (Dollars in thousands) Financial Instruments Cash Collateral Received September 30, 2021 $ 100,994 $ — $ 100,994 $ (10,560) $ — $ 90,434 December 31, 2020 $ 144,333 $ — $ 144,333 $ (94) $ — $ 144,239 Offsetting of Derivative Liabilities Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Statement of Financial Position Net Amounts of Liabilities Gross Amounts Not Offset in the Statement of Financial Position Net Amount (Dollars in thousands) Financial Instruments Cash Collateral Posted September 30, 2021 $ 105,513 $ — $ 105,513 $ (10,560) $ (80,719) $ 14,234 December 31, 2020 $ 153,433 $ — $ 153,433 $ (94) $ (150,238) $ 3,101 CASH FLOW HEDGES OF INTEREST RATE RISK The Company’s objectives in using certain interest rate derivatives are to add stability to net interest income and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. The Company has entered into derivative contracts to hedge the variable cash flows associated with certain FHLB borrowings. These interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company effectively making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. The Company’s cash flow hedge derivatives did not have any hedge ineffectiveness recognized in earnings during the nine months ended September 30, 2021. Characteristics of the Company’s interest rate derivative transactions designated as cash flow hedges of interest rate risk as of September 30, 2021, were as follows: (Dollars in thousands) Notional Effective (1) Estimated Increase/ Maturity Remaining Term Interest rate products: Issued 5/30/2019 $ 50,000 2.05% $ 641 6/1/2022 8 Issued 5/30/2019 50,000 2.03% 942 6/1/2023 20 Issued 5/30/2019 50,000 2.04% 948 6/1/2024 32 Issued 3/2/2020 50,000 0.98% 410 3/2/2025 41 Issued 3/20/2020 50,000 0.60% 219 3/20/2025 42 Total $ 250,000 $ 3,160 (1) The effective rate is adjusted for the difference between the three-month FHLB advance rate and three-month LIBOR.

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 and private banking customers to facilitate their respective risk management strategies. Those derivatives are simultaneously and economically hedged by offsetting derivatives that the Company executes with a third party, such that the Company generally eliminates its interest rate exposure resulting from such transactions. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings. As of September 30, 2021, the Company had interest rate derivative transactions with an aggregate notional amount of $4.55 billion related to this program. The table below presents the effect of the Company’s non-designated hedge instruments in the unaudited condensed consolidated statements of income: Three Months Ended September 30, Nine Months Ended September 30, (Dollars in thousands) 2021 2020 2021 2020 Derivatives not designated as hedging instruments: Location of Gain (Loss) Recognized in Income on Derivatives Amount of Gain (Loss) Recognized in Income on Derivatives Amount of Gain (Loss) Recognized in Income on Derivatives Interest rate products Non-interest income $ 10 $ 14 $ 33 $ (51) CREDIT-RISK-RELATED CONTINGENT FEATURES The Company has agreements with each of its derivative counterparties that contain a provision where, if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company has agreements with certain of its derivative counterparties that contain a provision where, if either the Company or the counterparty fails to maintain its status as a well-capitalized or adequately capitalized institution, then the Company or the counterparty could be required to terminate any outstanding derivative positions and settle its obligations under the agreement. As of September 30, 2021, the termination value of derivatives for which the Company had master netting arrangements with the counterparty and in a net liability position was $81.2 million, including accrued interest. As of September 30, 2021, the Company has minimum collateral posting thresholds with certain of its derivative counterparties and has posted collateral of $88.5 million which is considered restricted cash. If the Company had breached any of these provisions as of September 30, 2021, it could have been required to settle its obligations under the agreements at their termination value.

Fair Value Disclosures [Abstract]
DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS	DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS Fair value estimates of financial instruments are based on the present value of expected future cash flows, quoted market prices of similar financial instruments, if available, and other valuation techniques. These valuations are significantly affected by discount rates, cash flow assumptions and risk assumptions used. Therefore, fair value estimates may not be substantiated by comparison to independent markets and are not intended to reflect the proceeds that may be realized in an immediate settlement of instruments. Accordingly, the aggregate fair value amounts presented below do not represent the underlying value of the Company. FAIR VALUE MEASUREMENTS In accordance with U.S. GAAP, the Company must account for certain financial assets and liabilities at fair value on a recurring and non-recurring basis. The Company utilizes a three-level fair value hierarchy of valuation techniques to estimate the fair value of its financial assets and liabilities based on whether the inputs to those valuation techniques are observable or unobservable. The fair value hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within multiple levels of the fair value hierarchy, the lowest level input that has a significant impact on fair value measurement is used. Financial assets and liabilities are categorized based upon the following characteristics or inputs to the valuation techniques: • Level 1 – Financial assets and liabilities for which inputs are observable and are obtained from reliable quoted prices for identical assets or liabilities in actively traded markets. This is the most reliable fair value measurement and includes, for example, active exchange-traded equity securities. • Level 2 – Financial assets and liabilities for which values are based on quoted prices in markets that are not active or for which values are based on similar assets or liabilities that are actively traded. Level 2 also includes pricing models in which the inputs are corroborated by market data, for example, matrix pricing. • Level 3 – Financial assets and liabilities for which values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Level 3 inputs include assumptions of a source independent of the reporting entity or the reporting entity’s own assumptions that are supported by little or no market activity or observable inputs. The Company is responsible for the valuation process and as part of this process may use data from outside sources in establishing fair value. The Company performs due diligence to understand the inputs used or how the data was calculated or derived and 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, 2021 and December 31, 2020: September 30, 2021 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets / Financial assets: Debt securities available-for-sale: Corporate bonds $ — $ 137,021 $ — $ 137,021 Non-agency residential mortgage-backed securities — 243,688 — 243,688 Trust preferred securities — 18,778 — 18,778 Agency collateralized mortgage obligations — 17,558 — 17,558 Agency mortgage-backed securities — 125,105 — 125,105 Agency debentures — 8,288 — 8,288 Municipal bonds — 5,171 — 5,171 Equity securities 5,000 — — 5,000 Interest rate swaps — 100,994 — 100,994 Total financial assets 5,000 656,603 — 661,603 Financial liabilities: Interest rate swaps — 105,513 — 105,513 Total financial liabilities $ — $ 105,513 $ — $ 105,513 December 31, 2020 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets / Financial assets: Debt securities available-for-sale: Corporate bonds $ — $ 158,464 $ — $ 158,464 Trust preferred securities — 18,087 — 18,087 Agency collateralized mortgage obligations — 22,089 — 22,089 Agency mortgage-backed securities — 410,127 — 410,127 Agency debentures — 8,803 — 8,803 Interest rate swaps — 144,333 — 144,333 Total financial assets — 761,903 — 761,903 Financial liabilities: Interest rate swaps — 153,433 — 153,433 Total financial liabilities $ — $ 153,433 $ — $ 153,433 INVESTMENT SECURITIES Generally, debt securities are valued using pricing for similar securities, recently executed transactions, and other pricing models utilizing observable inputs and therefore are classified as Level 2. Equity securities (including mutual funds) are classified as Level 1 because these securities are in actively traded markets. INTEREST RATE SWAPS The fair value of interest rate swaps is estimated using inputs that are observable or that can be corroborated by observable market data and therefore are classified as Level 2. These fair value estimations include primarily market observable inputs such as the forward LIBOR swap curve. NON-RECURRING FAIR VALUE MEASUREMENTS Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment. The following tables represent the balances of assets measured at fair value on a non-recurring basis as of September 30, 2021 and December 31, 2020: September 30, 2021 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets Loans measured for impairment, net $ — $ — $ 1,725 $ 1,725 Other real estate owned — — 2,178 2,178 Total assets $ — $ — $ 3,903 $ 3,903 December 31, 2020 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets Loans measured for impairment, net $ — $ — $ 7,692 $ 7,692 Other real estate owned — — 2,724 2,724 Total assets $ — $ — $ 10,416 $ 10,416 As of September 30, 2021 and December 31, 2020, the Company recorded $6.9 million and $2.0 million, respectively, of specific reserves to allowance for credit losses on loans and leases as a result of adjusting the fair value of impaired loans. INDIVIDUALLY EVALUATED LOANS The Company evaluates individually loans that do not share similar risk characteristics, including non-accrual loans and loans designated as TDRs. Specific allowance for credit losses is measured based on a market approach, discounted cash flow of ongoing operations, discounted at the loan’s original effective interest rate, or a calculation of the fair value of the underlying collateral less estimated selling costs. Our policy is to obtain appraisals on collateral supporting individually evaluated loans on an annual basis, unless circumstances dictate a shorter time frame. Appraisals are reduced by estimated costs to sell the collateral, and, under certain circumstances, additional factors that may arise and cause us to believe our recoverable value may be less than the independent appraised value. Accordingly, individually evaluated loans are classified as Level 3. OTHER REAL ESTATE OWNED OREO is comprised of property acquired through foreclosure or voluntarily conveyed by borrowers. These assets are recorded on the date acquired at fair value, less estimated disposition costs, with the fair value being determined by appraisal. Our policy is to obtain appraisals on collateral supporting OREO on an annual basis, unless circumstances dictate a shorter time frame. Appraisals are reduced by estimated costs to sell the collateral and, under certain circumstances, additional factors that may arise and cause us to believe our recoverable value may be less than the independent appraised value. Accordingly, OREO 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, 2021 and December 31, 2020: September 30, 2021 (Dollars in thousands) Fair Value Valuation Techniques (1)(2) Significant Unobservable Inputs Weighted Average Discount Rate Loans measured for impairment, net $ 1,725 Collateral Liquidation value and discount due to salability conditions 80% Other real estate owned $ 2,178 Collateral Appraisal value and discount due to salability conditions 15% (1) Fair value is generally determined through independent appraisals of the underlying collateral, which may include Level 3 inputs that are not identifiable, or by using the discounted cash flow of ongoing operations if the loan is not collateral dependent. (2) The collateral which is used in the valuation of these loans is commercial real estate. December 31, 2020 (Dollars in thousands) Fair Value Valuation Techniques (1)(2) Significant Unobservable Inputs Weighted Average Loans measured for impairment, net $ 7,692 Collateral Appraisal value and discount due to salability conditions 23% Other real estate owned $ 2,724 Collateral Appraisal value and discount due to salability conditions 12% (1) Fair value is generally determined through independent appraisals of the underlying collateral, which may include Level 3 inputs that are not identifiable, or by using the discounted cash flow of ongoing operations if the loan is not collateral dependent. (2) The collateral which is used in the valuation of these loans is commercial real estate. FAIR VALUE OF FINANCIAL INSTRUMENTS The following table summarizes the carrying amounts and estimated fair values of financial instruments: September 30, 2021 December 31, 2020 (Dollars in thousands) Fair Value Carrying Estimated Carrying Estimated Financial assets: Cash and cash equivalents 1 $ 469,932 $ 469,932 $ 435,442 $ 435,442 Debt securities available-for-sale 2 555,609 555,609 617,570 617,570 Debt securities held-to-maturity, net 2 857,202 849,820 211,691 214,299 Equity securities 1 5,000 5,000 — — Federal Home Loan Bank stock 2 11,802 11,802 13,284 13,284 Loans and leases held-for-investment, net 3 9,836,648 9,815,390 8,202,788 8,199,922 Accrued interest receivable 2 21,872 21,872 18,783 18,783 Investment management fees receivable, net 2 8,908 8,908 7,935 7,935 Bank owned life insurance 2 98,308 98,308 71,787 71,787 Other real estate owned 3 2,178 2,178 2,724 2,724 Interest rate swaps 2 100,994 100,994 144,333 144,333 Financial liabilities: Deposits 2 $ 10,756,141 $ 10,767,182 $ 8,489,089 $ 8,510,799 Borrowings, net 2 355,654 364,201 400,493 402,714 Interest rate swaps 2 105,513 105,513 153,433 153,433 During the nine months ended September 30, 2021 and 2020, there were no transfers between fair value Levels 1, 2 or 3. The following methods and assumptions were used to estimate the fair value of each class of financial instruments as of September 30, 2021 and December 31, 2020: CASH AND CASH EQUIVALENTS The carrying amount approximates fair value. INVESTMENT SECURITIES The fair values of debt securities available-for-sale, debt securities held-to-maturity, debt securities trading and equity securities are based on quoted market prices for the same or similar securities, recently executed transactions and pricing models . FEDERAL HOME LOAN BANK STOCK The carrying value of our FHLB stock, which is carried at cost, approximates fair value. LOANS AND LEASES HELD-FOR-INVESTMENT The fair value of loans and leases held-for-investment is estimated by discounting the future cash flows using market rates (utilizing both unobservable and certain observable inputs when applicable) at which similar loans would be made to borrowers with similar credit ratings over the estimated remaining maturities. Impaired loans are generally valued at the fair value of the associated collateral. ACCRUED INTEREST RECEIVABLE The carrying amount approximates fair value. INVESTMENT MANAGEMENT FEES RECEIVABLE The carrying amount approximates fair value. BANK OWNED LIFE INSURANCE The fair value of general account BOLI is based on the insurance contract net cash surrender value. OTHER REAL ESTATE OWNED OREO is carried at fair value less estimated selling 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 deposits is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities. BORROWINGS The fair value of borrowings is calculated by discounting scheduled cash flows through the estimated maturity using period end market rates for borrowings of similar remaining maturities. INTEREST RATE SWAPS The fair value of interest rate swaps is estimated through the assistance of an independent third party and compared to the fair value determined by the swap counterparty to establish reasonableness. OFF-BALANCE SHEET INSTRUMENTS Fair values for the Company’s off-balance sheet instruments, which consist of lending commitments, standby letters of credit and risk participation agreements related to interest rate swap agreements, are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. Management believes that the fair value of these off-balance sheet instruments is not significant.

Use of estimates	USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States of America requires management to make estimates and assumptions that affect the reported amounts of certain assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of related revenues and expenses during the reporting period. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be different than those anticipated in the estimates, which could materially affect the financial results of our operations and financial condition. Material estimates that are particularly susceptible to significant changes relate to the determination of the allowance for credit losses on loans and leases, valuation of goodwill and other intangible assets and their evaluation for impairment, fair value measurements and deferred income taxes and their related recoverability, each of which is discussed later in this section.
Consolidation	CONSOLIDATION Our consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, the Bank, Chartwell and CTSC Securities, after elimination of inter-company accounts and transactions. The accounts of the Bank, in turn, include its wholly owned subsidiaries, TSC Equipment Finance and Meadowood, after elimination of inter-company accounts and transactions. The unaudited condensed consolidated financial statements of the Company presented herein have been prepared pursuant to SEC rules 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 unaudited condensed consolidated financial statements have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company and the related notes for the fiscal year ended December 31, 2020, included in the Company’s Annual Report on Form 10-K filed with the SEC on February 25, 2021.
Cash and cash equivalents	CASH AND CASH EQUIVALENTS For purposes of reporting cash flows, the Company has defined cash and cash equivalents as cash, interest-earning deposits with other institutions, federal funds sold and short-term investments that have an original maturity of 90 days or less. Under agreements with certain of its derivative counterparties, the Company is required to maintain minimum cash collateral posting thresholds with such counterparties. The cash subject to these agreements is considered restricted for these purposes.
Business combinations	BUSINESS COMBINATIONS The Company accounts for business combinations using the acquisition method of accounting. Under this method of accounting, the acquired company’s net assets are recorded at fair value as of the date of acquisition, and the results of operations of the acquired company are combined with our results from that date forward. Acquisition costs are expensed when incurred. The difference between the purchase price, which includes an initial measurement of any contingent earn out, and the fair value of the net assets acquired (including identified intangibles) is recorded as goodwill in the consolidated statements of financial condition. A change in the initial estimate of any contingent earn out amount is recorded to non-interest expense in the consolidated statements of income.
Investment securities	INVESTMENT SECURITIES The Company’s investments are classified as either: (1) held-to-maturity, which are debt securities that the Company intends to hold until maturity and are reported at amortized cost, net of allowance for credit losses; (2) trading, which are debt 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 non-interest income; (3) available-for-sale, which are debt securities not classified as either held-to-maturity or trading securities and reported at fair value, with unrealized gains and losses reported as a component of accumulated other comprehensive income (loss), on an after-tax basis; or (4) equity securities, which are reported at fair value, with unrealized gains and losses included in non-interest income. The cost of securities sold is determined on a specific identification basis. Amortization of premiums and accretion of discounts are recorded to interest income on investments over the estimated life of the security utilizing the level yield method. Management evaluates expected credit losses on held-to-maturity debt securities on a collective or pool basis, by investment category and credit rating. The Company measures credit losses by comparing the present value of cash flows expected to be collected to the amortized cost of the security that considers historical credit loss information, adjusted for current conditions and reasonable and supportable economic forecasts. The Company’s investment securities can be classified into the following pools based on similar risk characteristics: (1) U.S. government agencies, (2) state and local municipalities, (3) domestic corporations, including trust preferred securities, and (4) non-agency securitizations. The Company’s U.S. government agency securities are issued by U.S. government entities and agencies and are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. For the remaining pools of securities, the credit rating of the issuers, the investment’s cash flow characteristics and the underlying instruments securitizing certain bonds are the most relevant risk characteristics of the investment portfolio. The Company’s investment policy only allows for purchases of investments with investment grade credit ratings and the Company continuously monitors for changes in credit ratings. Probability of default and loss given default rates are based on historical averages for each investment pool, adjusted to reflect the impact of a single, forward-looking forecast of certain macroeconomic variables, such as unemployment rates and interest rate spreads, which management considers to be both reasonable and supportable. The forecast of these macroeconomic variables is applied over a period of three years and reverts to historical averages over a two-year reversion period. Management evaluates available-for-sale debt securities in an unrealized loss position quarterly for expected credit losses. Management first determines whether it intends to sell or if it is more likely than not that it will be required to sell the impaired securities. This determination considers current and forecasted liquidity requirements, regulatory and capital requirements, and securities portfolio management. If the Company intends to sell an available-for-sale security with a fair value below amortized cost or if it is more likely than not that it will be required to sell such a security before recovery, the security’s amortized cost is written down to fair value through current period earnings. For available-for-sale debt securities that the Company does not intend to sell or it is more likely than not that it will not be required to sell before recovery, a provision for credit losses is recorded through current period earnings for the amount of the valuation decline below amortized cost that is attributable to credit losses. Management considers the extent to which fair value is less than amortized cost, credit ratings and other factors related to the security in assessing whether credit loss exists. The Company measures credit loss by comparing the present value of cash flows expected to be collected to the amortized cost of the security. An allowance for credit losses is measured by the difference that the present value of cash flows expected to be collected is less than the amortized cost, limited by the amount that the fair value is less than the amortized cost. The remaining difference between the security’s fair value and amortized cost (that is, the decline in fair value not attributable to credit losses) is recognized in other comprehensive income (loss), in the consolidated statements of comprehensive income and the shareholders’ equity section of the consolidated statements of financial condition, on an after-tax basis. Changes in the allowance for credit losses are recorded as provision for credit losses. Losses are charged against the allowance when management believes the security is uncollectible or management intends to sell or is required to sell the security. The recognition of interest income on a debt security is discontinued when any principal or interest payment becomes 90 days past due, at which time the debt security is placed on non-accrual status. All accrued and unpaid interest on such debt security is then reversed. Accrued interest receivable is excluded from the estimate of expected credit losses.
Federal Home Loan Bank stock	FEDERAL HOME LOAN BANK STOCK The Bank is a member of the Federal Home Loan Bank (“FHLB”) of Pittsburgh. Member institutions are required to invest in FHLB stock. The stock is carried at cost, which approximates its liquidation value, and it is evaluated for impairment based on the ultimate recoverability of the par value. The following matters are considered by management when evaluating the FHLB stock for impairment: the ability of the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; the impact of legislative and regulatory changes on the institution and its customer base; and the Company’s intent and ability to hold its FHLB stock for the foreseeable future. Management believes the Company’s holdings in the FHLB stock were recoverable at par value as of September 30, 2021 and December 31, 2020. Cash and stock dividends are reported as interest income on investments in the consolidated statements of income.
Loans and leases	LOANS AND LEASES Loans and leases held-for-investment are stated at amortized cost. Amortized cost is the unpaid principal balance, net of deferred loan fees and costs. Loans held-for-sale are stated at the lower of cost or fair value. Interest income on loans is accrued at the contractual rate on the principal amount outstanding. Deferred loan fees and costs are amortized to interest income over the estimated life of the loan, taking into consideration scheduled payments and prepayments. The Company considers a loan to be a troubled debt restructuring (“TDR”) when there is a concession made to a financially troubled borrower without adequate consideration provided to the Company. The Company evaluates any loan reasonably expected to become a TDR, regardless of whether the loan is on accrual or non-accrual status. Once a loan is deemed to be a TDR, the Company considers whether the loan should be placed on non-accrual status. In assessing accrual status, the Company considers the likelihood that repayment and performance according to the original contractual terms will be achieved, as well as the borrower’s historical payment performance. A loan is designated and reported as a TDR until such loan is either paid off or sold unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is fully expected that the remaining principal and interest will be collected according to the restructured agreement. The recognition of interest income on a loan is discontinued when, in management’s opinion, it is probable the borrower is unable to meet payments as they become due or when the loan becomes 90 days past due, whichever occurs first, at which time the loan is placed on non-accrual status. All accrued and unpaid interest on such loans is then reversed. The 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 The Company is a party to financial instruments with off-balance sheet risk, such as 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 lending agreement with such customer. Commitments generally have fixed expiration dates or other termination clauses (e.g., loans due on demand) and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the unfunded commitment amount does not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis using the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The amount of collateral obtained, if deemed necessary by the Company upon extension of a commitment, is based on management’s credit evaluation of the borrower.
Other real estate owned	OTHER REAL ESTATE OWNED Real estate owned, other than bank premises, is recorded at fair value less estimated selling costs. Fair value is determined based on an independent appraisal. Expenses related to holding the property are charged against earnings when incurred. Depreciation is not recorded on other real estate owned (“OREO”) properties.
Allowance for credit losses and leases	ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASES The allowance for credit losses is a valuation account that is deducted from the amortized cost of loans and leases to present management’s best estimate of the net amount expected to be collected. Adjustments to the allowance for credit losses are established through provisions for credit losses that are recorded in the consolidated statements of income. Loans and leases are charged off against the allowance for credit losses when management believes that the principal is uncollectible. If, at a later time, amounts are recovered with respect to loans and leases previously charged off, the recovered amount is credited to allowance for credit losses. Accrued interest receivable is excluded from the estimate of expected credit losses. The allowance for credit losses represents estimates of expected credit losses for homogeneous loan pools that share similar risk characteristics such as commercial and industrial (“C&I”) loans and leases, commercial real estate (“CRE”) loans, and private banking loans, which include consumer lines of credit and residential mortgages. The Company periodically reassesses each loan pool to ensure that the loans within the pool continue to share similar risk characteristics. Non-accrual loans and loans designated as TDRs are assessed individually using a discounted cash flow method or, where a loan is collateral dependent, based upon the fair value of the collateral less estimated selling costs. The collateral on our private banking loans that are secured by cash, marketable securities and/or cash value life insurance is monitored daily and requires borrowers to continually replenish such collateral as a result of changes in its fair value. Therefore, it is expected that the fair value of the collateral securing each loan will exceed the loan’s amortized cost and no allowance for credit losses would be required under Accounting Standard Codification (“ASC”) 326-20-35-6, “Financial Assets Secured by Collateral Maintenance Provisions.” In estimating the general allowance for credit losses for loans evaluated on a collective or pool basis, management considers past events, current conditions, and reasonable and supportable economic forecasts, including historical charge-offs and subsequent recoveries. Management also considers qualitative factors that influence our credit quality, including, but not limited to, delinquency and non-performing loan trends, changes in loan underwriting guidelines and credit policies, and the results of internal loan reviews. Finally, management considers the impact of changes in current and forecasted local and regional economic conditions in the markets that we serve. Management bases the computation of the general allowance for credit losses 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: C&I loans and leases, CRE loans and private banking loans (other than those secured by cash, marketable securities and/or cash value life insurance). For each portfolio, management estimates expected credit losses over the life of each loan utilizing lifetime or cumulative loss rate methodology, which identifies macroeconomic factors and asset-specific characteristics that are correlated with credit loss experience, including loan age, loan type, leverage, risk rating, interest rate spread and industry. The lifetime loss rate is applied to the amortized cost of the loan. This methodology builds on default and recovery probabilities by utilizing pool-specific historical loss rates to calculate expected credit losses. These pool-specific historical loss rates may be adjusted for a forecast of certain macroeconomic variables, as further discussed below, and other factors such as differences in underwriting standards, portfolio mix, or when historical asset terms do not reflect the contractual terms of the financial assets being evaluated as of the measurement date. Each time the Company measures expected credit losses, the Company assesses the relevancy of historical loss information and considers any necessary adjustments to address any differences in asset-specific characteristics. The allowance for credit losses represents management’s current estimate of expected credit losses in the loan and lease portfolio. Expected credit losses are estimated over the contractual term of the loans, which includes extension or renewal options that are not unconditionally cancellable by the Company and are adjusted for expected prepayments when appropriate. Management’s judgment takes into consideration past events, current conditions and reasonable and supportable economic forecasts including 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 in making such determinations, and that the present allowance for credit losses represents management’s best estimate of current expected credit losses, 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. The lifetime loss rates are estimated by analyzing a combination of internal and external data related to historical performance of each loan pool over a complete economic cycle. Loss rates are based on historical averages for each loan pool, adjusted to reflect the impact of a single, forward-looking forecast of certain macroeconomic variables such as gross domestic product (“GDP”), unemployment rates, corporate bond credit spreads and commercial property values, which management considers to be both reasonable and supportable. The single, forward-looking forecast of these macroeconomic variables is applied over the remaining life of the loan pools. The development of the reasonable and supportable forecast incorporates an assumption that each macroeconomic variable will revert to a long-term expectation starting in years two to four of the forecast and largely completing within the first five years of the forecast. The secondary factor is intended to capture additional risks related to events and circumstances that management believes have an impact on the performance of the loan portfolio that are not considered as part of the primary factor. Although this factor is more subjective in nature, the methodology focuses on internal and external trends in pre-specified categories, or risk factors, and applies a quantitative percentage that drives the secondary factor. Nine risk factors have been identified and each risk factor is assigned an allowance level based on management’s judgment as to the expected impact of each risk factor on each loan portfolio and is monitored on a quarterly basis. As the trend in any risk factor changes, management evaluates the need for a corresponding change to occur in the allowance associated with each respective risk factor to provide the most appropriate estimate of allowance for credit losses on loans and leases. The Company also maintains an allowance for credit losses on off-balance sheet credit exposures for unfunded loan commitments. This allowance is reflected as a component of other liabilities which represents management’s current estimate of expected losses in the unfunded loan commitments. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life based on management’s consideration of past events, current conditions and reasonable and supportable economic forecasts. 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 credit losses on outstanding loans. Unconditionally cancellable loans are excluded from the calculation of allowance for credit losses on off-balance sheet credit exposures. Results for the nine months ended September 30, 2021 are presented under the current expected credit loss (“CECL”) methodology, in accordance with ASC Topic 326, while prior period amounts continue to be reported in accordance with ASC Topic 450, “Contingencies,” and specific reserves based upon ASC Topic 310, “Receivables.” ASC Topic 450 applies to homogeneous loan pools such as commercial loans, consumer lines of credit and residential mortgages that are not individually evaluated for impairment. ASC Topic 310 is applied to commercial and consumer loans that are individually evaluated for impairment.
Investment management fees	INVESTMENT MANAGEMENT FEES The Company recognizes investment management fee revenue when advisory services are performed. Fees are based on assets under management and are calculated pursuant to individual client contracts. Investment management fees are generally received on a quarterly basis. Certain incremental costs incurred to acquire some of our investment management contracts are deferred and amortized to non-interest expense over the estimated life of the contract.
Goodwill and other intangible assets	GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill is not amortized and is subject to at least annual assessments for impairment by applying a fair value-based test. The Company reviews goodwill annually and again at any quarter-end if a material event occurs during the quarter that may affect goodwill. If goodwill testing is required, an assessment of qualitative factors can be completed before performing a goodwill impairment test. If an assessment of qualitative factors determines it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, then a goodwill impairment test is not required. Other intangible assets represent purchased assets that may lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. The Company has determined that certain of its acquired mutual fund client relationships meet the criteria to be considered indefinite-lived assets because the Company expects both the renewal of these contracts and the cash flows generated by these assets to continue indefinitely. Accordingly, the Company does not amortize these intangible assets, but instead reviews these assets annually or more frequently whenever events or circumstances occur indicating that the recorded indefinite-lived assets may be impaired. Each reporting period, the Company assesses whether events or circumstances have occurred which indicate that the indefinite life criteria are no longer met. If the indefinite life criteria are no longer met, the Company assesses whether the carrying value of these assets exceeds its fair value. If the carrying value exceeds the fair value of the assets, an impairment loss is recorded in an amount equal to any such excess and the assets are reclassified to finite-lived. Other intangible assets that the Company has determined to have finite lives, such as its trade names, client lists and non-compete agreements are amortized over their estimated useful lives. These finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives, which range from four
Office properties and equipment	OFFICE PROPERTIES AND EQUIPMENT Office properties and equipment are stated at cost less accumulated depreciation. Office properties include furniture, fixtures and leasehold improvements. Equipment includes computer equipment and internal use software. Depreciation is computed utilizing 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
Operating leases	OPERATING LEASES The Company is a lessee in noncancellable operating leases, primarily for its office spaces and other office equipment. The Company records operating leases as a right-of-use asset and an offsetting lease liability in the consolidated statements of financial condition at the present value of the unpaid lease payments. The Company generally uses its incremental borrowing rate as the discount rate for operating leases. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the right-of-use asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
Bank owned life insurance	BANK OWNED LIFE INSURANCE Bank owned life insurance (“BOLI”) policies on certain officers and employees are recorded at net cash surrender value on the consolidated statements of financial condition. Upon termination of a BOLI policy, the Company receives the cash surrender value. BOLI benefits are payable to the Company upon the death of the insured. Changes in net cash surrender value are recognized as non-interest income in the consolidated statements of income.
Deposits	DEPOSITS Deposits are stated at principal outstanding. Interest on deposits is accrued and charged to interest expense daily and is paid or credited in accordance with the terms of the respective accounts.
Borrowings	BORROWINGS The Company records FHLB advances, line of credit borrowings and subordinated notes payable at their principal amount, net of debt issuance costs. Interest expense is recognized based on the coupon rate of the obligations. Costs associated with the acquisition of subordinated notes payable are amortized to interest expense over the expected term of the borrowing.
Income taxes	INCOME TAXES The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the tax effects of differences between the financial statement and tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities with regard to a change in tax rates is recognized in income in the period that includes the enactment date. Management assesses all available evidence to determine the amount of deferred tax assets that are more likely than not to be realized. The available evidence used in connection with the assessments includes taxable income in prior periods, projected taxable income, potential tax planning strategies and projected reversals of deferred tax items. These assessments involve a degree of subjectivity and may undergo significant change. Changes to the evidence used in the assessments could have a material adverse effect on the Company’s results of operations in the period in which they occur. The Company considers uncertain tax positions that it has taken or expects to take on a tax return. Any interest and penalties related to unrecognized tax benefits would be recognized in income tax expense in the consolidated statements of income.
Earnings per common share	EARNINGS PER COMMON SHARE Earnings per common share (“EPS”) is computed using the two-class method. The two-class method is an earnings allocation formula that determines earnings per share for common stock and participating securities, according to dividends and participation rights in undistributed earnings. Under this method, net earnings is reduced by the amount of dividends declared in the current period for common shareholders and participating security holders. The remaining earnings or “undistributed earnings” are allocated between common stock and participating securities to the extent that each security may share in earnings as if all the earnings for the period had been distributed. The two-class method requires the Company’s Series C perpetual non-cumulative convertible non-voting preferred stock (the “Series C Preferred Stock”) and outstanding warrants to be treated as participating classes of securities in the computation of EPS. In addition, net income is reduced by dividends declared on all series of preferred stock to derive net income available to common
Stock-based compensation	STOCK-BASED COMPENSATION The Company accounts for its stock-based compensation awards based on estimated fair values of stock-based awards made to employees and directors. Compensation cost for all stock-based payments is based on the estimated grant-date fair value. The value of the portion of the award that is ultimately expected to vest is included in compensation and employee benefits expense in the consolidated statements of income and recorded as a component of additional paid-in capital. Compensation expense for all awards is recognized on a straight-line basis over the requisite service period for the entire grant.
Derivatives and hedging activities	DERIVATIVES AND HEDGING ACTIVITIES All derivatives are evaluated at inception as to whether they are hedging or non-hedging activities. All derivatives are recognized as either assets or liabilities on the consolidated statements of financial condition and measured at fair value. For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. Any hedge ineffectiveness would be recognized in the income statement line item pertaining to the hedged item. For derivatives designated as cash flow hedges, changes in fair value of the effective portion of the cash flow hedges are reported in accumulated other comprehensive income (loss). When the cash flows associated with the hedged item are realized, the gain or loss included in accumulated other comprehensive income (loss) is recognized in the consolidated statements of income. The Company also has interest rate derivative positions that are not designated as hedging instruments. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings. The Company is required to have minimum collateral posting thresholds with certain of its derivative counterparties, and this collateral is considered restricted cash. The Company executes interest rate derivatives with its commercial banking customers to facilitate their respective risk management strategies. The Company generates swap fee income through these transactions. These derivatives are simultaneously and economically hedged by offsetting derivatives that the Company executes with a third party, such that the Company generally eliminates its interest rate exposure resulting from such transactions, and these derivatives are not designated as hedging instruments. Swap fees are based on the notional amount and weighted maturity of each individual transaction and are collected and recorded to non-interest income in the consolidated statements of income when the transaction is executed.
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 such 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 must be recorded for certain assets and liabilities every reporting period on a recurring basis or, under certain circumstances, on a non-recurring basis.
Accumulated other comprehensive income (loss)	ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) Unrealized holding gains and the non-credit component of unrealized losses on the Company’s debt 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 debt securities reclassified into the held-to-maturity category from the available-for-sale category. Unrealized holding gains (losses) on the effective portion of the Company’s cash flow hedge derivatives are included in accumulated other comprehensive income (loss), net of applicable income taxes, which will be reclassified to interest expense as interest payments are made on the Company’s debt. Income tax effects in accumulated other comprehensive income (loss) are released as investments are sold or mature and as liabilities are extinguished.
Treasury stock	TREASURY STOCK The repurchase of the Company’s common stock is recorded at cost. At the time of reissuance, the treasury stock account is reduced using the average cost method. Gains and losses on the reissuance of common stock are recorded in additional paid-in capital, to the extent additional paid-in capital from any previous net gains on treasury share transactions exists. Any net deficiency is charged to retained earnings.
Recent accounting developments	RECENT ACCOUNTING DEVELOPMENTS In July 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2021-5, Leases (Topic 842): Lessors—Certain Leases with Variable Lease Payments. The amendments are effective for fiscal years beginning after December 15, 2021, for all entities, and for interim periods within those fiscal years for public business entities and interim periods within fiscal years beginning after December 15, 2022, for all other entities. The amendments in this update address stakeholders’ concerns by amending the lease classification requirements for lessors to align them with practice under Topic 840. Lessors should classify and account for a lease with variable lease payments that do not depend on a reference index or a rate as an operating lease if both of the following criteria are met: ( 1) the lease would have been classified as a sales-type lease or a direct financing lease in accordance with the classification criteria in paragraphs 842-10-25-2 through 25-3; and (2) the lessor would have otherwise recognized a day-one loss. The Company is currently evaluating the impact of adopting ASU 2021-05 on its consolidated financial statements. In April 2021, the FASB issued ASU 2021-04, which included Topic 260: Earnings Per Share. This guidance clarifies and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options ("warrants") due to a lack of explicit guidance in the FASB Codification. A SU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2021-04 on its consolidated financial statements. In January 2021, the FASB issued ASU 2021-01 - Reference Rate Reform (Topic 848): Scope. This ASU clarifies the scope of Topic 848 so that derivatives affected by the discounting transition are explicitly eligible for certain optional expedients and exceptions in Topic 848. The amendments in this ASU are elective and apply to all entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The amendments in this ASU are effective immediately for all entities. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements, but the Company will consider this guidance as contracts are transitioned from LIBOR to another reference rate.
Reclassification	RECLASSIFICATION Certain items previously reported have been reclassified to conform with the current year’s reporting presentation and are considered immaterial.
