Accounting Policies [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation This quarterly report presents the consolidated financial statements of Lakeland Bancorp, Inc. and its subsidiaries, including Lakeland Bank (“Lakeland”) and Lakeland’s wholly owned subsidiaries (collectively, the “Company”). The accounting and reporting policies of the Company conform with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and predominant practices within the banking industry. The Company’s unaudited interim financial statements reflect all adjustments, such as normal recurring accruals that are in the opinion of management, necessary for the fair presentation of the results of the interim periods. The results of operations for the nine months ended September 30, 2020 do not necessarily indicate the results that the Company will achieve for all of 2020. Certain information and footnote disclosures required under U.S. GAAP have been condensed or omitted, as permitted by rules and regulations of the Securities and Exchange Commission. These unaudited interim financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes that are presented in the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2019. Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS On January 4, 2019, the Company completed its acquisition of Highlands Bancorp, Inc. ("Highlands"), a bank holding company headquartered in Vernon, New Jersey. Highlands was the parent of Highlands State Bank, which operated four branches in Sussex, Passaic and Morris Counties in New Jersey. This acquisition enabled the Company to broaden its presence in those counties. Effective as of the close of business on January 4, 2019, Highlands merged into the Company and Highlands State Bank merged into Lakeland. Pursuant to the merger agreement, the shareholders of Highlands received for each outstanding share of Highlands common stock that they owned at the effective time of the merger, 1.015 shares of Lakeland Bancorp, Inc. common stock. The Company issued 2,837,524 shares of its common stock in the merger. Outstanding Highlands stock options were paid out in cash at the difference between $14.71 and an average strike price of $8.09 for a total cash payment of $797,000. The acquisition was accounted for under the acquisition method of accounting and accordingly, the assets acquired and liabilities assumed in the acquisition were recorded at their estimated fair values as of the acquisition date. Highlands' assets were recorded at their preliminary estimated fair values as of January 4, 2019 and Highlands' results of operations have been included in the Company's Consolidated Statements of Income from that date forward. The assets acquired and liabilities assumed in the acquisition were recorded at their estimated fair values based on management's best estimates using information available at the date of the acquisition, including the use of a third-party valuation specialist. During the second quarter of 2019, the Company revised the estimated fair value of the acquired assets as of the acquisition date as the result of additional information obtained. The adjustment related to credit-impaired loans acquired in the acquisition that were recorded at fair value and subsequently accounted for in accordance with Accounting Standards Codification ("ASC") Subtopic 310-30 and resulted in a $1.7 million increase in goodwill. As a result of new information obtained during the third quarter of 2019, about facts and circumstances that existed as of the acquisition date, the Company revised the estimated fair value on two Highlands branches acquired. The adjustment resulted in an increase in goodwill of $447,000. The following table summarizes the estimated fair value of the acquired assets and liabilities assumed at the date of acquisition for Highlands. (in thousands) Assets acquired: Cash and cash equivalents $ 13,454 Securities, available for sale 21,234 Securities, held to maturity 1,500 Federal Home Loan Bank stock 1,767 Loans held for sale 1,113 Loans 425,005 Premises and equipment 2,613 Goodwill 19,844 Identifiable intangible assets 3,728 Accrued interest receivable and other assets 6,244 Total assets acquired 496,502 Liabilities assumed: Deposits (409,638) Other borrowings (27,800) Subordinated debt (13,157) Other liabilities (2,490) Total liabilities assumed (453,085) Net assets acquired $ 43,417 Loans acquired in the Highlands acquisition were recorded at fair value and subsequently accounted for in accordance with ASC Topic 310. There was no carryover related allowance for loan losses. The fair values of loans acquired from Highlands were estimated using cash flow projections based on the remaining maturity and repricing terms. Cash flows were adjusted for estimated future credit losses and the rate of prepayments. Projected cash flows were then discounted to present value using a risk-adjusted market rate for similar loans. The following is a summary of the credit impaired loans acquired in the Highlands acquisition as of the closing date. (in thousands) Contractually required principal and interest at acquisition $ 22,363 Contractual cash flows not expected to be collected (non-accretable difference) 7,129 Expected cash flows at acquisition $ 15,234 Interest component of expected cash flows (accretable difference) 1,431 Fair value of acquired loans $ 13,803 The core deposit intangible totaled $3.7 million and is being amortized over its estimated useful life of approximately ten years using an accelerated method. The goodwill will be evaluated annually for impairment. The goodwill is not deductible for tax purposes. The fair values of deposit liabilities with no stated maturities such as checking, money market and savings accounts, were assumed to equal the carrying amounts since these deposits are payable on demand.

Revenue Recognition

Revenue Recognition	9 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition	REVENUE RECOGNITION The Company’s primary source of revenue is interest income generated from loans and investment securities. Interest income is recognized according to the terms of the financial instrument agreement over the life of the loan or investment security unless it is determined that the counterparty is unable to continue making interest payments. Interest income also includes prepaid interest fees from commercial customers, which approximates the interest foregone on the balance of the loan prepaid. The Company’s additional source of income, also referred to as noninterest income, is generated from deposit related fees, interchange fees, loan fees, merchant fees, loan sales, investment services and other miscellaneous income and is largely based on contracts with customers. In these cases, the Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The Company considers a customer to be any party to which the Company will provide goods or services that are an output of the Company’s ordinary activities in exchange for consideration. There is little seasonality with regards to revenue from contracts with customers and all inter-company revenue is eliminated when the Company’s financial statements are consolidated. Generally, the Company enters into contracts with customers that are short-term in nature where the performance obligations are fulfilled and payment is processed at the same time. Such examples include revenue related to merchant fees, interchange fees and investment services income. In addition, revenue generated from existing customer relationships such as deposit accounts are also considered short-term in nature, because the relationship may be terminated at any time and payment is processed at the time performance obligations are fulfilled. As a result, the Company does not have contract assets, contract liabilities or related receivable accounts for contracts with customers. In cases where collectability is a concern, the Company does not record revenue. Generally, the pricing of transactions between the Company and each customer is either (i) established within a legally enforceable contract between the two parties, as is the case with loan sales, or (ii) disclosed to the customer at a specific point in time, as is the case when a deposit account is opened or before a new loan is underwritten. Fees are usually fixed at a specific amount or as a percentage of a transaction amount. No judgment or estimates by management are required to record revenue related to these transactions and pricing is clearly identified within these contracts. The Company primarily operates in one geographic region, Northern and Central New Jersey and contiguous areas. Therefore, all significant operating decisions are based upon analysis of the Company as one operating segment or unit. We disaggregate our revenue from contracts with customers by contract-type and timing of revenue recognition, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Noninterest income not generated from customers during the Company’s ordinary activities primarily relates to income from bank owned life insurance, gains/losses on the sale of investment securities, gains/losses on the sale of other real estate owned, gains/losses on the sale of property, plant and equipment and mortgage servicing rights. The following table sets forth the components of noninterest income for the three and nine months ended September 30, 2020 and 2019: For the Three Months Ended September 30, For the Nine Months Ended September 30, (in thousands) 2020 2019 2020 2019 Deposit Related Fees and Charges: Debit card interchange income $ 1,472 $ 1,429 $ 3,910 $ 4,059 Overdraft charges 533 1,047 1,935 3,024 ATM service charges 138 226 367 626 Demand deposit fees and charges 129 124 394 389 Savings service charges 16 25 57 81 Total 2,288 2,851 6,663 8,179 Commissions and Fees: Loan fees 510 303 1,063 1,182 Wire transfer charges 372 316 1,021 888 Investment services income 392 474 1,231 1,253 Merchant fees 184 202 598 586 Commissions from sales of checks 73 85 216 299 Safe deposit income 85 94 256 275 Other income 51 66 138 187 Total 1,667 1,540 4,523 4,670 Gains on sales of loans 1,437 486 2,562 1,285 Other Income: Gains on customer swap transactions 624 730 4,234 1,585 Title insurance income 46 9 126 128 Other income 200 627 370 755 Total 870 1,366 4,730 2,468 Revenue not from contracts with customers 511 457 1,787 2,210 Total Noninterest Income $ 6,773 $ 6,700 $ 20,265 $ 18,812 Timing of Revenue Recognition: Products and services transferred at a point in time 6,243 6,224 18,422 16,546 Products and services transferred over time 19 19 56 56 Revenue not from contracts with customers 511 457 1,787 2,210 Total Noninterest Income $ 6,773 $ 6,700 $ 20,265 $ 18,812

Fair value below cost is solely due to interest rate movements and is deemed temporary. Investment securities, including mortgage-backed securities, asset-backed securities and corporate securities, are evaluated on a periodic basis to determine if factors are identified that would require further analysis. In evaluating the Company’s securities, management considers the following items: • The Company’s ability and intent to hold the securities, including an evaluation of the need to sell the security to meet certain liquidity measures, or whether the Company has sufficient levels of cash to hold the identified security in order to recover the entire amortized cost of the security; • The financial condition of the underlying issuer; • The credit ratings of the underlying issuer and if any changes in the credit rating have occurred; • The length of time the security’s fair value has been less than amortized cost; and • Adverse conditions related to the security or its issuer if the issuer has failed to make scheduled payments or other factors. If the above factors indicate that an additional analysis is required, management will perform a discounted cash flow analysis evaluating the security. Equity securities at fair value The Company has an equity securities portfolio which consists of investments in other financial institutions for market appreciation purposes and investments in Community Reinvestment funds. The market value of these investments was $14.1 million and $16.5 million at September 30, 2020 and December 31, 2019, respectively. The Company recorded purchases of $1.2 million and $259,000 for the nine months ended September 30, 2020 and 2019, respectively. For the three and nine months ended September 30, 2020 and for the three months ended September 30, 2019, the Company recorded no sales of equity securities and recorded proceeds from sales of equity securities of $1.2 million for the nine months ended September 30, 2019. The Company recorded a market value loss of $170,000 for the third quarter of 2020 and $72,000 in market value gain for the third quarter of 2019 on equity securities. For the nine months ended September 30, 2020, the Company recorded $625,000 in market value losses and $525,000 in market value gains for the nine months ended September 30, 2019 on equity securities. Market value gain or loss on equity securities are recorded in noninterest income. As of September 30, 2020, the equity investments in other financial institutions and Community Reinvestment funds had a market value of $898,000 and $13.2 million, respectively. The Community Reinvestment funds include $3.5 million that are primarily invested in community development loans that are guaranteed by the Small Business Administration (“SBA”). Because the funds are primarily guaranteed by the federal government, there are minimal changes in market value between accounting periods. These funds can be redeemed with 60 days' notice at the net asset value less unpaid management fees with the approval of the fund manager. As of September 30, 2020, the net amortized cost equaled the market value of the investment. There are no unfunded commitments related to these investments.

Interest that would have been accrued on impaired loans during the first nine months of 2020 and 2019 had the loans been performing under original terms would have been $1.3 million and $703,000, respectively. Credit Quality Indicators The class of loans is determined by internal risk rating. Management closely and continually monitors the quality of its loans and assesses the quantitative and qualitative risks arising from the credit quality of its loans. Lakeland assigns a credit risk rating to all commercial loans and loan commitments. The credit risk rating system has been developed by management to provide a methodology to be used by loan officers, department heads and senior management in identifying various levels of credit risk that exist within Lakeland’s commercial loan portfolios. The risk rating system assists senior management in evaluating Lakeland’s commercial loan portfolio, analyzing trends, and determining the proper level of required reserves to be recommended to the Board. In assigning risk ratings, management considers, among other things, a borrower’s debt service coverage, earnings strength, loan to value ratios, guarantor support, industry conditions and economic conditions. Management categorizes commercial loans and commitments into a one (1) to nine (9) numerical structure with rating 1 being the strongest rating and rating 9 being the weakest.

Allowance for Loan Losses The Coronavirus Aid, Relief and Economic Security ("CARES") Act, a stimulus package signed into law on March 27, 2020 to address economic disruption caused by the COVID-19 pandemic, provided financial institutions with the option to defer adoption of the Financial Accounting Standards Board's Accounting Standard Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326) until the earlier of the end of the pandemic or December 31, 2020. The Company elected to defer adoption of ASU 2016-13 and its Current Expected Credit Loss methodology ("CECL").

In addition to the allowances described above, Lakeland also maintains a reserve for unfunded lending commitments which is included in other liabilities. This reserve was $2.0 million and $1.8 million as of September 30, 2020 and December 31, 2019, respectively. The Company analyzes the adequacy of the reserve for unfunded lending commitments quarterly. Troubled Debt Restructurings Loans are classified as troubled debt restructured loans ("TDR") in cases where borrowers experience financial difficulties and Lakeland makes certain concessionary modifications to contractual terms. Restructured loans typically involve a modification of terms such as a reduction of the stated interest rate, a moratorium of principal payments and/or an extension of the maturity date at a stated interest rate lower than the current market rate of a new loan with similar risk. The Company considers the potential losses on these loans as well as the remainder of its impaired loans while considering the adequacy of the allowance for loan losses. Section 4013 of the CARES Act, as interpreted by the "Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working With Customers Affected by the Coronavirus (Revised)" (“Revised Statement”), dated April 17, 2020, includes criteria that enable financial institutions to exclude from TDR status loans that are modified in connection with COVID-19. Under these provisions, TDR status is not required for the term of a loan modification if (i) the loan modification is made in connection with COVID-19, (ii) the loan was not past due more than 30 days as of December 31, 2019 and (iii) the loan modification is entered into during the period between March 1, 2020, and the earlier of (a) 60 days after COVID-19 is no longer characterized as a National Emergency or (b) December 31, 2020. Furthermore, pursuant to the Revised Statement, for loan modifications that do not meet these criteria but are made in connection with COVID-19, such loans may be presumed not to be TDR if the loan was current at the time the loan modification program was implemented and the modifications are short-term (e.g., six months). If the criteria are not met under either Section 4013 or the Revised Statement, banks are required to follow their existing accounting policies to determine whether COVID-related modifications should be accounted for as a TDR. The Company has elected to suspend the classification of loan modifications as TDR if they qualify under Section 4013 or the Revised Statement. For past due status, the CARES Act also provides for lenders to continue to report loans in the same delinquency bucket they were in at the time of modification. The Company has applied this guidance related to modifications during the first half of 2020. As of June 30, 2020, commercial loans totaling $927.0 million were granted 90-day, COVID-related payment deferments, of which 91% were commercial real estate loans. In addition, payment deferments on equipment finance loans totaled $40.0 million and residential and consumer loans totaled $53.0 million at June 30, 2020. During the third quarter of 2020, new payment deferments were granted to six loan relationships totaling $6.4 million. At September 30, 2020, approximately $149.0 million in commercial loans, $3.0 million in equipment finance loans and $3.0 million in residential mortgage and consumer loans remained on COVID-related deferral. During the third quarter, many 90-day loan deferments expired and borrowers began paying their pre-deferral loan payments. For most commercial loans, borrowers are paying their pre-deferral loan payments plus an additional monthly amount to catch up on the payments that were deferred. The following table summarizes the loans that were restructured during the three and nine months ended September 30, 2020 and 2019 that met the definition of a TDR: Three Months Ended Three Months Ended (dollars in thousands) Number of Pre- Post- Number of Pre- Post- Home equity and consumer — $ — $ — 2 $ 83 $ 83 — $ — $ — 2 $ 83 $ 83 Nine Months Ended Nine Months Ended (dollars in thousands) Number of Pre- Post- Number of Pre- Post- Home equity and consumer — $ — $ — 2 $ 83 $ 83 — $ — $ — 2 $ 83 $ 83 The following table summarizes as of September 30, 2020 and 2019, loans that were TDRs within the previous twelve months that have subsequently defaulted: September 30, 2020 September 30, 2019 (dollars in thousands) Number of Recorded Number of Recorded Construction 1 $ 694 — $ — Home equity and consumer — — 2 83 1 $ 694 2 $ 83 Other Real Estate and Other Repossessed Assets At September 30, 2020 the Company had no other real estate owned and at December 31, 2019, the Company had other real estate owned of $563,000, consisting of residential property acquired as a result of foreclosure proceedings. There were no other repossessed assets at either September 30, 2020 or December 31, 2019.

Leases

Leases [Abstract]
Leases	LEASES The Company leases certain premises and equipment under operating leases. Portions of certain properties are subleased for terms extending through 2024. At September 30, 2020, the Company had lease liabilities totaling $18.5 million and right-of-use assets totaling $17.0 million related to these leases. At December 31, 2019, the Company had lease liabilities totaling $19.8 million and right-of-use assets totaling $18.3 million. The calculated amount of the right-of-use assets and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of the minimum lease payments. The Company's lease agreements often include one or more options to renew at the Company's discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the right-of-use asset and lease liability. The Company uses its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. For the nine months ended September 30, 2020, the weighted average remaining lease term for operating leases was 9.87 years and the weighted average discount rate used in the measurement of operating lease liabilities was 3.41%. As the Company elected not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance and utilities. Lease costs were as follows: For the Three Months Ended September 30, For the Nine Months Ended September 30, (in thousands) 2020 2019 2020 2019 Operating lease cost $ 828 $ 819 $ 2,484 $ 2,465 Short-term lease cost — — — — Variable lease cost 22 32 87 100 Sublease income $ (31) $ (31) (92) (92) Net lease cost $ 819 $ 820 $ 2,479 $ 2,473 The table below presents other information on the Company's operating leases for the nine months ended September 30, 2020 and 2019: Nine Months Ended September 30, (in thousands) 2020 2019 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 2,085 $ 1,977 Right-of-use asset obtained in exchange for new operating lease liabilities 741 765 There were no sale and leaseback transactions, leveraged leases or lease transactions with related parties during the three and nine months ended September 30, 2020. At September 30, 2020, the Company had no leases that had not yet commenced. A maturity analysis of operating lease liabilities and a reconciliation of the undiscounted cash flows to the total operating lease liability at September 30, 2020 are as follows: (in thousands) Within one year $ 3,309 After one year but within three years 5,405 After three years but within five years 4,320 After 5 years 9,160 Total undiscounted cash flows 22,194 Discount on cash flows (3,723) Total lease liability $ 18,471

Derivatives

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	DERIVATIVES Lakeland is a party to interest rate derivatives that are not designated as hedging instruments. Under a program, Lakeland executes interest rate swaps with commercial lending customers to facilitate their respective risk management strategies. These interest rate swaps with customers are simultaneously offset by interest rate swaps that Lakeland executes with a third-party financial institution, such that Lakeland minimizes its net risk exposure resulting from such transactions. Because the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The changes in the fair value of the swaps offset each other, except for the credit risk of the counterparties, which is determined by taking into consideration the risk rating, probability of default and loss given default for all counterparties. Lakeland had $100.9 million and $30.0 million, respectively, in available for sale securities pledged for collateral on its interest rate swaps with financial institutions at September 30, 2020 and December 31, 2019. In June 2016, the Company entered into two cash flow hedges in order to hedge the variable cash outflows associated with its subordinated debentures. The notional value of these hedges was $30.0 million. The Company’s objectives in using cash flow hedges are to add stability to interest expense and to manage its exposure to interest rate movements. The Company used interest rate swaps designated as cash flow hedges which involved 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. In these particular hedges the Company is paying a third party an average of 1.10% in exchange for a payment at 3 month LIBOR. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the nine months ended September 30, 2020, the Company did not record any hedge ineffectiveness. The Company recognized $17,000 and $334,000 of accumulated other comprehensive income that was reclassified into interest expense for the first nine months of 2020 and 2019, respectively. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s debt. During the next twelve months, the Company estimates that $260,000 will be reclassified as an increase to interest expense should the rate environment remain the same. The following table presents summary information regarding these derivatives for the periods presented (dollars in thousands): September 30, 2020 Notional Amount Average Weighted Average Weighted Average Fair Classified in Other Assets: Customer interest rate swaps 919,460 9.2 3.78 % 1 Mo.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	GOODWILL AND INTANGIBLE ASSETS The Company had goodwill of $156.3 million at both September 30, 2020 and December 31, 2019. The Company recorded $19.8 million in goodwill from the Highlands merger in January 2019. The Company reviews its goodwill and intangible assets annually, on November 30, or more frequently if conditions warrant, for impairment. In testing goodwill for impairment, the Company compares the estimated fair value of its reporting unit to its carrying amount, including goodwill. The Company has determined that it has one reporting unit, Community Banking. At September 30, 2020, the Company evaluated whether it is more likely than not that the fair value of our one reporting unit is less than its carrying amount, by assessing relevant events and circumstances as a result of the impact of COVID-19 and concluded that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount. The Company had core deposit intangibles of $3.5 million and $4.3 million at September 30, 2020 and December 31, 2019, respectively. The Company recorded core deposit intangibles of $3.7 million for the Highlands acquisition in January 2019. The estimated future amortization expense for the remainder of 2020 and for each of the succeeding five years ended December 31 is as follows (in thousands): For the Year Ended 2020 $ 250 2021 868 2022 711 2023 554 2024 425 2025 317

Debt Disclosure [Abstract]
Borrowings	BORROWINGS At September 30, 2020 and December 31, 2019, the Company had overnight and short-term borrowings from the Federal Home Loan Bank ("FHLB") totaling $40.0 million and $200.0 million, respectively. In addition, there were no overnight and short-term borrowings from correspondent banks at September 30, 2020 and these borrowings totaled $85.0 million at December 31, 2019. Other short-term borrowings at September 30, 2020 and December 31, 2019 consisted of short-term securities sold under agreements to repurchase of $57.9 million and $43.7 million, respectively. The securities sold under agreements to repurchase are overnight sweep arrangement accounts with our customers. As of September 30, 2020, the Company had $72.9 million in mortgage backed securities pledged for its securities sold under agreements to repurchase. At times the market values of securities collateralizing our securities sold under agreements to repurchase may decline due to changes in interest rates and may necessitate our lenders to issue a “margin call” which requires Lakeland to pledge additional collateral to meet that margin call. Advances from the FHLB totaled $135.1 million at September 30, 2020 compared to $165.8 million at December 31, 2019 and were collateralized by first mortgage loans. The advances have prepayment penalties. In the first quarter of 2020, the Company repaid two advances totaling $10.0 million and recorded $356,000 in long-term debt prepayment fees.

Fair Value Disclosures [Abstract]
Fair Value Measurement and Fair Value of Financial Instruments	FAIR VALUE MEASUREMENT AND FAIR VALUE OF FINANCIAL INSTRUMENTS Fair Value Measurement Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels giving the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest level priority to unobservable inputs (level 3 measurements). The following describes the three levels of fair value hierarchy: Level 1 – unadjusted quoted prices in active markets for identical assets or liabilities; includes U.S. Treasury Notes, and other U.S. Government Agency securities that actively trade in over-the-counter markets; equity securities and mutual funds that actively trade in over-the-counter markets. Level 2 – quoted prices for similar assets or liabilities in active markets; or quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs other than quoted prices that are observable for the asset or liability including yield curves, volatilities and prepayment speeds. Level 3 – unobservable inputs for the asset or liability that reflect the Company’s own assumptions about assumptions that market participants would use in the pricing of the asset or liability and that are consequently not based on market activity but upon particular valuation techniques. The Company’s assets that are measured at fair value on a recurring basis are its available for sale investment securities and its interest rate swaps. The Company obtains fair values on its securities using information from a third-party servicer. If quoted prices for securities are available in an active market, those securities are classified as Level 1 securities. The Company has U.S. Treasury Notes and certain equity securities that are classified as Level 1 securities. Level 2 securities were primarily comprised of U.S. Agency bonds, residential mortgage-backed securities, obligations of state and political subdivisions and corporate securities. Fair values were estimated primarily by obtaining quoted prices for similar assets in active markets or through the use of pricing models supported with market data information. Standard inputs include benchmark yields, reported trades, broker-dealer quotes, issuer spreads, bids and offers. On a quarterly basis, the Company reviews the pricing information received from the Company’s third-party pricing service. This review includes a comparison to non-binding third-party quotes. The fair values of derivatives are based on valuation models from a third party using current market terms (including interest rates and fees), the remaining terms of the agreements and the credit worthiness of the counter party as of the measurement date (Level 2). The following table sets forth the Company’s financial assets that were accounted for at fair value on a recurring basis as of the periods presented by level within the fair value hierarchy. During the nine months ended September 30, 2020, the Company did not make any transfers between any levels within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement: (in thousands) Quoted Prices in Significant Significant Total September 30, 2020 Assets: Investment securities, available for sale U.S. Treasury and government agencies $ 10,955 $ 62,320 $ — $ 73,275 Mortgage-backed securities — 476,827 — 476,827 Asset-backed securities — 40,711 — 40,711 Obligations of states and political subdivisions — 164,710 — 164,710 Debt securities — 27,808 — 27,808 Total securities available for sale 10,955 772,376 — 783,331 Equity securities, at fair value 898 13,178 — 14,076 Derivative assets — 95,243 — 95,243 Total Assets $ 11,853 $ 880,797 $ — $ 892,650 Liabilities: Derivative liabilities $ — $ 95,449 $ — $ 95,449 Total Liabilities $ — $ 95,449 $ — $ 95,449 December 31, 2019 Assets: Investment securities, available for sale U.S. Treasury and government agencies $ 12,580 $ 123,067 $ — $ 135,647 Mortgage-backed securities — 551,064 — 551,064 Obligations of states and political subdivisions — 60,021 — 60,021 Debt securities — 9,168 — 9,168 Total securities available for sale 12,580 743,320 — 755,900 Equity securities, at fair value 1,735 14,738 — 16,473 Derivative assets — 27,123 — 27,123 Total Assets $ 14,315 $ 785,181 $ — $ 799,496 Liabilities: Derivative liabilities $ — $ 26,852 $ — $ 26,852 Total Liabilities $ — $ 26,852 $ — $ 26,852 The following table sets forth the Company’s assets subject to fair value adjustments (impairment) on a non-recurring basis. Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement: (in thousands) (Level 1) (Level 2) (Level 3) Total September 30, 2020 Assets: Impaired loans $ — $ — $ 4,224 $ 4,224 Loans held for sale — 4,197 — 4,197 December 31, 2019 Assets: Impaired loans $ — $ — $ 5,789 $ 5,789 Loans held for sale — 1,743 — 1,743 Other real estate owned and other repossessed assets — — 563 563 Impaired loans are evaluated and valued at the time the loan is identified as impaired at the lower of cost or market value. Because most of Lakeland’s impaired loans are collateral dependent, fair value is generally measured based on the value of the collateral, less estimated costs to sell, securing these loans and is classified at a level 3 in the fair value hierarchy. Collateral may be real estate, accounts receivable, inventory, equipment and/or other business assets. The value of real estate is assessed based on appraisals by qualified third-party licensed appraisers. The appraisers may use the income approach to value the collateral using discount rates (with ranges of 5-11%) or capitalization rates (with ranges of 4-9%) to evaluate the property. The value of the equipment may be determined by an appraiser, if significant, inquiry through a recognized valuation resource, or by the value on the borrower’s financial statements. Field examiner reviews on business assets may be conducted based on the loan exposure and reliance on this type of collateral. Appraised and reported values may be adjusted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and client’s business. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors identified above. The Company has a held for sale loan portfolio that consists of residential mortgages that are being sold in the secondary market. The Company records these mortgages at the lower of cost or market value. Fair value is generally determined by the value of purchase commitments. Other real estate owned (“OREO”) and other repossessed assets, representing property acquired through foreclosure or deed in lieu of foreclosure, are carried at fair value less estimated disposal costs of the acquired property. Fair value on other real estate owned is based on the appraised value of the collateral using discount rates or capitalization rates similar to those used in impaired loan valuation. The fair value of other repossessed assets is estimated by inquiry through recognized valuation resources. Changes in the assumptions or methodologies used to estimate fair values may materially affect the estimated amounts. Changes in economic conditions, locally or nationally, could impact the value of the estimated amounts of impaired loans, OREO and other repossessed assets. Fair Value of Certain Financial Instruments Estimated fair values have been determined by the Company using the best available data and an estimation methodology suitable for each category of financial instruments. Management is concerned that there may not be reasonable comparability between institutions due to the wide range of permitted assumptions and methodologies in the absence of active markets. This lack of uniformity gives rise to a high degree of subjectivity in estimating financial instrument fair values. The estimation methodologies used, the estimated fair values and recorded book balances at September 30, 2020, and December 31, 2019, are outlined below. This summary, as well as the table below, excludes financial assets and liabilities for which carrying value approximates fair value. For financial assets, these include cash and cash equivalents. For financial liabilities, these include noninterest-bearing demand deposits, savings and interest-bearing transaction accounts and federal funds purchased and securities sold under agreements to repurchase. The estimated fair value of demand, savings and interest-bearing transaction accounts is the amount payable on demand at the reporting date. Carrying value is used because there is no stated maturity on these accounts, and the customer has the ability to withdraw the funds immediately. Also excluded from this summary and the following table are those financial instruments recorded at fair value on a recurring basis, as previously described. The fair value of investment securities held to maturity is measured using information from the same third-party servicer used for investment securities available for sale using the same methodologies discussed above. Investment securities held to maturity includes $2.5 million in subordinated debt that are non-rated and do not have an active secondary market or information readily available on standard financial systems. As a result, the securities are classified as Level 3 securities. Management performs a credit analysis before investing in these securities. FHLB stock is an equity interest that can be sold to the issuing FHLB, to other FHLBs, or to other member banks at its par value. Because ownership of these securities is restricted, they do not have a readily determinable fair value. As such, the Company’s FHLB stock is recorded at cost or par value and is evaluated for impairment each reporting period by considering the ultimate recoverability of the investment rather than temporary declines in value. The Company’s evaluation primarily includes an evaluation of liquidity, capitalization, operating performance, commitments, and regulatory or legislative events. The net loan portfolio has been valued using an exit price approach, which incorporates a buildup discount rate calculation that uses a swap rate adjusted for credit risk, servicing costs, a liquidity premium and a prepayment premium. For fixed maturity certificates of deposit, fair value is estimated based on the present value of discounted cash flows using the rates currently offered for deposits of similar remaining maturities. The carrying amount of accrued interest payable approximates its fair value. The fair value of long-term debt is based upon the discounted value of contractual cash flows. The Company estimates the discount rate using the rates currently offered for similar borrowing arrangements. The fair value of subordinated debentures is based on bid/ask prices from brokers for similar types of instruments. The fair values of commitments to extend credit and standby letters of credit are estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of guarantees and letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date. The fair value of commitments to extend credit and standby letters of credit are deemed immaterial.
