Operating results for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2021. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the SEC. Basis of Financial Statement Presentation The accompanying unaudited condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Except as disclosed herein, there has been no material change in the information disclosed in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated. In the opinion of management, the consolidated financial statements contain all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of the statements of financial position, results of operations, and cash flow for the interim periods. Recent Accounting Pronouncements FASB ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ” In March 2020, the FASB issued “Reference Rate Reform (Topic 848)” which provides optional expedients and exceptions for contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The guidance is effective for contract modifications as of March 12, 2020 through December 31, 2022. The Company is actively working to amend and address impacted contracts to allow for a replacement index. Additionally, the Company is currently evaluating the optional expedients and exceptions and has not yet determined the impact this standard may have on its consolidated financial statements.

At June 30, 2021 and December 31, 2020, the Company had not recorded an ACL on available-for-sale securities. Accrued interest receivable on held-to-maturity debt securities totaled $3.5 million at June 30, 2021 and is excluded from the estimate of expected credit losses. The estimate of expected credit losses considers historical credit loss information adjusted for current conditions and reasonable and supportable forecasts. At June 30, 2021, the ACL on held-to-maturity securities was $0.4 million. During the three and six months ended June 30, 2021, there were no sales of available-for-sale investment securities. Proceeds from sales of available-for-sale investment securities during the six months ended June 30, 2020 were immaterial. Other Investments At June 30, 2021 and December 31, 2020, other investments totaled $51.0 million and $48.8 million, respectively. As a member of the FHLB system administered by the Federal Housing Finance Agency, the Bank is required to maintain a minimum investment in capital stock with the FHLB consisting of membership stock and activity-based stock. The FHLB capital stock of $12.0 million and $10.8 million at June 30, 2021 and December 31, 2020, respectively, is recorded at cost, which represents redemption value, and is included in other investments in the consolidated balance sheets. The remaining amounts in other investments primarily include various investments in SBICs, CDFIs, private equity investments, and the Company’s investment in unconsolidated trusts used to issue preferred securities to third parties.

The loan balance at June 30, 2021 also includes a net premium on acquired loans of $20.6 million. At June 30, 2021 loans of $2.8 billion were pledged to FHLB and the Federal Reserve Bank. PPP loans totaled $709.9 million at December 31, 2020, or $698.6 million net of unearned fees of $11.3 million. The loan balance includes a net premium on acquired loans of $16.1 million at December 31, 2020. At December 31, 2020 loans of $2.5 billion were pledged to FHLB and the Federal Reserve Bank. The Company has elected to present the accrued interest receivable balance separate from amortized cost basis, to exclude accrued interest receivable balances from the tabular disclosures, and not to estimate an ACL on accrued interest receivable as these amounts are timely written off as a credit loss expense. Accrued interest receivable totaled $24.6 million at June 30, 2021 and was reported in Other Assets on the consolidated balance sheets.

The Company utilizes three forecasts in the model: Moody’s baseline, a stronger near-term growth upside and a moderate recession downside forecast. The Company weights these scenarios at 70%, 5%, and 25%, respectively, which added approximately $12.9 million to the ACL over the baseline model. These forecasts incorporate an accommodative monetary policy and the current and anticipated impact of government stimulus. The Company has also recognized the risk posed by loans that have received multiple deferrals of principal and interest payments, loans in the hospitality sector, and loans with other specific identified risks by allocating additional reserves to those segments. Some of the key risks to the forecasts that could result in future provision for credit losses are additional shutdowns and self-quarantines if another significant wave of COVID hits, the vaccination process stalls, small-business bankruptcies occur at higher levels, or unemployment increases.

This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings: • Grades 1, 2, and 3 – Includes loans to borrowers with a continuous record of strong earnings, sound balance sheet condition and capitalization, ample liquidity with solid cash flow, and whose management team has experience and depth within their industry. • Grade 4 – Includes loans to borrowers with positive trends in profitability, satisfactory capitalization and balance sheet condition, and sufficient liquidity and cash flow. • Grade 5 – Includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization, liquidity, and cash flow. • Grade 6 – Includes loans to borrowers where an adverse change or perceived weakness has occurred, but may be correctable in the near future. Alternatively, this rating category may also include circumstances where the borrower is starting to reverse a negative trend or condition, or has recently been upgraded from a 7, 8, or 9 rating. • Grade 7 – Watch credits are borrowers that have experienced financial setback of a nature that is not determined to be severe or influence ‘ongoing concern’ expectations. Although possible, no loss is anticipated at this time, due to strong collateral and/or guarantor support. • Grade 8 – Substandard credits include those borrowers characterized by significant losses and sustained downward trends in balance sheet condition, liquidity, and cash flow. Repayment reliance may have shifted to secondary sources. Collateral exposure may exist and additional reserves may be warranted. • Grade 9 – Doubtful credits include borrowers that may show deteriorating trends that are unlikely to be corrected.

Commitments and Contingencies Disclosure [Abstract]
Commitments	COMMITMENTS AND CONTINGENCIES The Company issues financial instruments with off balance sheet risk in the normal course of the business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company’s extent of involvement and maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. The contractual amounts of off-balance-sheet financial instruments are as follows: (in thousands) June 30, 2021 December 31, 2020 Commitments to extend credit $ 1,982,555 $ 1,946,068 Letters of credit 55,571 50,971 Off-Balance Sheet Credit Risk Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments usually have fixed expiration dates or other termination clauses, may have significant usage restrictions, and may require payment of a fee. Of the total commitments to extend credit at June 30, 2021, and December 31, 2020, approximately $167.3 million and $160.6 million, respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon or may be revoked, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate. Other liabilities includes $5.4 million and $5.7 million for estimated losses attributable to the unadvanced commitments at June 30, 2021, and December 31, 2020, respectively. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance or payment of a customer to a third party. These standby letters of credit are issued to support contractual obligations of the Company’s customers. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. As of June 30, 2021, the approximate remaining terms of standby letters of credit range from 1 month to 3 years. Contingencies The Company and its subsidiaries are, from time to time, parties to various legal proceedings arising out of their businesses. Management believes there are no such proceedings pending or threatened against the Company or its subsidiaries which, if determined adversely, would have a material adverse effect on the business, consolidated financial condition, results of operations or cash flows of the Company or any of its subsidiaries.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS Risk Management Objective of Using Derivatives The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s borrowings. The Company does not enter into derivative financial instruments for trading purposes. Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. These derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. The Company has executed a series of cash flow hedges to fix the effective interest rate for payments due on $62.0 million of LIBOR-based junior subordinated debentures to a weighted-average-fixed rate of 2.62%. Select terms of the hedges are as follows: $ in thousands Notional Fixed Rate Maturity Date $ 15,465 2.60 % March 15, 2024 $ 14,433 2.60 % March 30, 2024 $ 18,558 2.64 % March 15, 2026 $ 13,506 2.64 % March 17, 2026 For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income and subsequently reclassified into interest expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are paid on the Company’s variable-rate debt. During the next twelve months, the Company estimates that an additional $1.5 million will be reclassified as an increase to interest expense. Non-designated Hedges Derivatives not designated as hedges are not considered speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting derivatives the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate derivatives associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings as a component of other noninterest income. The table below presents the fair value of the Company’s derivative financial instruments: Notional Amount Derivative Assets Derivative Liabilities (in thousands) June 30, December 31, 2020 June 30, December 31, 2020 June 30, December 31, 2020 Derivatives Designated as Hedging Instruments: Interest rate swap $ 61,962 $ 61,962 $ — $ — $ 4,379 $ 5,987 Derivatives not Designated as Hedging Instruments: Interest rate swap $ 983,018 $ 1,026,016 $ 19,809 $ 28,703 $ 19,846 $ 28,980 Derivative assets are classified on the balance sheet in other assets.
