Mortgage-backed and asset-backed securities are not shown by maturity because expected maturities may differ from contractual maturities due to underlying loan prepayments of the issuer. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

There were proceeds from sales of available for sale securities of $94.7 million for the nine months ended September 30, 2020 with gross gains on sales of securities of $569,000 and gross losses on sales of securities of $227,000. Gains or losses on sales of securities are based on the net proceeds and the adjusted carrying amount of the securities sold using the specific identification method. In the second quarter of 2021, the Company recorded a gain on a called security of $9,000. During the third quarter of 2021, the Company transferred $494.2 million of previously designated available for sale securities to a held to maturity designation at estimated fair value. The reclassification for the period ended September 30, 2021 is permitted as the Company has appropriately determined the ability and intent to hold these securities as an investment until maturity or call. The securities transferred had an unrealized net gain of $3.8 million at the time of transfer, which is reflected, net of taxes, in accumulated other comprehensive income on the consolidated balance sheet. Subsequent amortization will be recognized over the life of the securities. The Company recorded net amortization of $158,000 during the third quarter of 2021. Securities with a carrying value of approximately $675.5 million and $578.0 million at September 30, 2021 and December 31, 2020, respectively, were pledged to secure public deposits and for other purposes required by applicable laws and regulations.

If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost, a credit loss exists and an allowance is created, limited by the amount that the fair value is less than the amortized cost basis. For held to maturity securities, management measures expected credit losses on a collective basis by major security type. All of the mortgage-backed securities are issued by U.S. government 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 and, therefore, the expectation of non-payment is zero. A range of historical losses method is utilized in estimating the net amount expected to be collected for mortgage-backed securities, collateralized mortgage obligations and obligations of states and political subdivisions. Credit Quality Indicators Credit ratings, which are updated monthly, are a key measure for estimating the probability of a bond's default and for monitoring credit quality on an on-going basis. For bonds other than U.S. Treasuries and bonds issued or guaranteed by U.S. government agencies, credit ratings issued by one or more nationally recognized statistical rating organizations are considered in conjunction with an assessment by the Company's management. Investment grade reflects a credit quality of BBB or above.

The fair value of the equity portfolio was $16.4 million and $14.7 million at September 30, 2021 and December 31, 2020, respectively. For the three and nine months ended September 30, 2021, the Company recorded no sales of equity securities and recorded sales of Community Reinvestment funds totaling $3.0 million for the three and nine months ended September 30, 2020. The Company recorded fair value losses on equity securities of $58,000 and $170,000 for the third quarter of 2021 and 2020, respectively. For the nine months ended September 30, 2021 and 2020, the Company recorded fair value losses of $191,000 and $625,000, respectively. Fair value gain or loss on equity securities are recorded in noninterest income. As of September 30, 2021, the Company's investments in 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 fair 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, 2021, the net amortized cost equaled the fair value of the investment. There are no unfunded commitments related to these investments. The Community Reinvestment funds also include $12.9 million of investment in government guaranteed loans, mortgage-backed securities, small business loans and other instruments supporting affordable housing and economic development as of September 30, 2021. The Company may redeem these funds at the net asset value calculated at the end of the current business day less any unpaid management fees. There are no restrictions on redemptions for the holdings in these investments other than the notice required by the fund manager. There are no unfunded commitments related to these investments.

The Company had no loans included in total non-accrual loans that were in the process of foreclosure at September 30, 2021 and $1.7 million in residential mortgages and consumer home equity loans included in total non-accrual loans that were in the process of foreclosure at December 31, 2020. 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 CARES Act provided relief from TDR classification for certain loan modifications related to the COVID-19 pandemic beginning March 1, 2020 through the earlier of 60 days after the end of the pandemic or December 31, 2020. Additionally, banking regulatory agencies issued interagency guidance that COVID-19 related short-term modifications (i.e., six months or less) granted to borrowers that were current as of the loan modification program implementation date do not need to be considered TDRs. The Consolidated Appropriations Act, 2021 (the "CAA"), which was signed into law on December 27, 2020, extended this guidance to modifications made until the earlier of January 1, 2022 or 60 days after the end of the COVID-19 national emergency. The Company elected this provision of the CARES Act and excluded modified loans that met the required guidelines for relief from its TDR classification. At September 30, 2021, no loans were on COVID-related deferrals as the remaining 90-day loan deferments expired and borrowers began paying their pre-deferral loan payments in the first quarter of 2021. 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. None of these modifications were considered TDRs. At September 30, 2021 and December 31, 2020, TDRs totaled $3.7 million and $5.0 million, respectively. Accruing TDRs totaled $3.4 million and non-accrual TDRs totaled $241,000 at September 30, 2021. Accruing TDRs and non-accrual TDRs totaled $3.9 million and $1.1 million, respectively, at December 31, 2020. There was one consumer loan totaling $116,000 that was restructured during the three and nine months ended September 30, 2021 and that met the definition of a TDR, while no loans were restructured during the three and nine months ended September 30, 2020. There were no restructured loans that subsequently defaulted in the nine months ended September 30, 2021; however, one construction loan totaling $694,000 that was a TDR within the previous twelve months had subsequently defaulted in the nine months ended September 30, 2020." id="sjs-B4">Loans When the Company adopted Financial Accounting Standards Board's Accounting Standard Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326) ("ASU 2016-13") for measuring credit losses, the loan portfolio segmentation was expanded to nine portfolio segments, taking into consideration common loan attributes and risk characteristics, as well as historical reporting metrics and data availability. All disclosures as of and for the three and nine months ended September 30, 2021, and as of December 31, 2020, are presented in accordance with ASU 2016-13. The Company did not reclassify prior comparative financial periods and has presented those disclosures under previously applicable U.S. GAAP. The following sets forth the composition of the Company’s loan portfolio: (in thousands) September 30, 2021 December 31, 2020 Non-owner occupied commercial $ 2,300,637 $ 2,398,946 Owner occupied commercial 884,144 827,092 Multifamily 907,903 813,225 Non-owner occupied residential 177,592 200,229 Commercial, industrial and other 473,324 718,189 Construction 332,868 266,883 Equipment finance 119,709 116,690 Residential mortgage 407,021 377,380 Home equity and consumer 277,604 302,598 Total $ 5,880,802 $ 6,021,232 Loans are recognized at amortized cost, which includes principal balance and net deferred loan fees and costs. The Company elected to exclude accrued interest receivable from amortized cost. Accrued interest receivable is reported separately in the Consolidated Balance Sheets and totaled $13.5 million at September 30, 2021 and $16.0 million at December 31, 2020. Loan origination fees and certain direct loan origination costs are deferred and the net fee or cost is recognized in interest income as an adjustment of yield. Net deferred loan fees are included in loans by respective segment and total $7.7 million at September 30, 2021 and $10.0 million at December 31, 2020. At September 30, 2021 and December 31, 2020, Small Business Association ("SBA") Paycheck Protection Program ("PPP") loans totaled $109.3 million and $284.6 million, respectively and are included in the balance of commercial, industrial and other loans. Consumer loans included overdraft deposit balances of $188,000 and $650,000, at September 30, 2021 and December 31, 2020, respectively. At September 30, 2021 and December 31, 2020, the Company had $2.29 billion and $2.28 billion of loans pledged for potential borrowings at the Federal Home Loan Bank of New York ("FHLB"). The Company transferred approximately $21.7 million of commercial and residential mortgage loans from the loan portfolio to loans held for sale during the nine months ended September 30, 2021 and subsequently sold these loans. Excluding the loan transfers, there were no other sales of loans from the held for investment portfolio during the nine months ended September 30, 2021. Credit Quality Indicators 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 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 the loan portfolios. The risk rating system assists senior management in evaluating the loan portfolio and analyzing trends. In assigning risk ratings, management considers, among other things, the borrower’s ability to service the debt based on relevant information such as current financial information, historical payment experience, credit documentation, public information and current economic conditions. Management categorizes loans and commitments into the following risk ratings: Pass: "Pass" assets are well protected by the current net worth and paying capacity of the obligor or guarantors, if any, or by the fair value of any underlying collateral. Watch: "Watch" assets require more than the usual amount of monitoring due to declining earnings, strained cash flow, increasing leverage and/or weakening market. These borrowers generally have limited additional debt capacity and modest coverage and average or below average asset quality, margins and market share. Any residential or consumer loan currently on deferment in accordance with the Coronavirus Aid, Relief and Economic Security ("CARES") Act or the interagency statement issued by bank regulatory agencies has been classified by management as watch or worse. Special Mention: "Special mention" assets exhibit identifiable credit weakness, which if not checked or corrected could weaken the loan quality or inadequately protect the bank’s credit position at some future date. Substandard: "Substandard" assets are inadequately protected by the current sound worth and paying capacity of the obligors or of the collateral pledged, if any. A substandard loan has a well-defined weakness or weaknesses that may jeopardize the liquidation of the debt. Doubtful: "Doubtful" assets that exhibit all of the weaknesses inherent in substandard loans, but have the added characteristics that the weaknesses make collection or liquidation in full improbable on the basis of existing facts. Loss: “Loss” is a rating for loans or portions of loans that are considered uncollectible and of such little value that their continuance as bankable loans is not warranted.

have not been received as of the date such payments were contractually due. A loan is generally considered non-performing when it is placed on non-accrual status. A loan is generally placed on non-accrual status when it becomes 90 days past due if such loan has been identified as presenting uncertainty with respect to the collectability of interest and principal. A loan past due 90 days or more may remain on accruing status if such loan is both well secured and in the process of collection. In the absence of other intervening factors, loans granted payment deferrals related to COVID-19 are not reported as past due or placed on non-accrual status provided the borrowers have met the criteria in the CARES Act or otherwise have met the criteria included in an interagency statement issued by bank regulatory agencies.

The Company had no loans included in total non-accrual loans that were in the process of foreclosure at September 30, 2021 and $1.7 million in residential mortgages and consumer home equity loans included in total non-accrual loans that were in the process of foreclosure at December 31, 2020. 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 CARES Act provided relief from TDR classification for certain loan modifications related to the COVID-19 pandemic beginning March 1, 2020 through the earlier of 60 days after the end of the pandemic or December 31, 2020. Additionally, banking regulatory agencies issued interagency guidance that COVID-19 related short-term modifications (i.e., six months or less) granted to borrowers that were current as of the loan modification program implementation date do not need to be considered TDRs. The Consolidated Appropriations Act, 2021 (the "CAA"), which was signed into law on December 27, 2020, extended this guidance to modifications made until the earlier of January 1, 2022 or 60 days after the end of the COVID-19 national emergency. The Company elected this provision of the CARES Act and excluded modified loans that met the required guidelines for relief from its TDR classification. At September 30, 2021, no loans were on COVID-related deferrals as the remaining 90-day loan deferments expired and borrowers began paying their pre-deferral loan payments in the first quarter of 2021. 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. None of these modifications were considered TDRs. At September 30, 2021 and December 31, 2020, TDRs totaled $3.7 million and $5.0 million, respectively. Accruing TDRs totaled $3.4 million and non-accrual TDRs totaled $241,000 at September 30, 2021. Accruing TDRs and non-accrual TDRs totaled $3.9 million and $1.1 million, respectively, at December 31, 2020. There was one consumer loan totaling $116,000 that was restructured during the three and nine months ended September 30, 2021 and that met the definition of a TDR, while no loans were restructured during the three and nine months ended September 30, 2020. There were no restructured loans that subsequently defaulted in the nine months ended September 30, 2021; however, one construction loan totaling $694,000 that was a TDR within the previous twelve months had subsequently defaulted in the nine months ended September 30, 2020.

Allowance for Credit Losses

Allowance for Credit Losses	9 Months Ended

Receivables [Abstract]
Allowance for Credit Losses	Allowance for Credit Losses The Company adopted ASU 2016-13, which requires the measurement of expected credit losses for financial assets measured at amortized cost, including loans and certain off-balance-sheet credit exposures. See Note 1 - Summary of Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 for a description of the adoption of ASU 2016-13 and the Company's allowance methodology. The Company recorded an increase in the allowance for credit losses on loans of $6.7 million effective January 1, 2020. Prior year disclosures have not been restated. Under the standard, the Company's methodology for determining the allowance for credit losses on loans is based upon key assumptions, including the lookback periods, historic net charge-off factors, economic forecasts, reversion periods, prepayments and qualitative adjustments. The allowance is measured on a collective, or pool, basis when similar risk characteristics exist. Loans that do not share common risk characteristics are evaluated on an individual basis and are excluded from the collective evaluation. At September 30, 2021, loans totaling $5.86 billion were evaluated collectively and the allowance on these balances totaled $57.3 million and loans evaluated on an individual basis totaled $16.6 million with the specific allocations of the allowance for credit losses totaling $666,000. Allowance for Credit Losses - Loans The allowance for credit losses on loans is summarized in the following table: For the Three Months Ended September 30, For the Nine Months Ended September 30, (in thousands) 2021 2020 2021 2020 Balance at beginning of the period $ 60,389 $ 57,839 $ 71,124 $ 40,003 Charge-offs (996) (682) (4,128) (1,306) Recoveries 1,266 85 1,785 322 Net recoveries (charge-offs) 270 (597) (2,343) (984) (Benefit) provision for credit loss - loans (2,706) 8,000 (10,828) 26,223 Balance at end of the period $ 57,953 $ 65,242 $ 57,953 $ 65,242 The benefit for credit losses for the three and nine months ended September 30, 2021 was largely due to an improvement in economic conditions utilized in the calculation. Accrued interest receivable on loans, reported as a component of accrued interest receivable on the consolidated balance sheets, totaled $13.5 million at September 30, 2021 and $16.0 million at December 31, 2020. The Company made the election to exclude accrued interest receivable from the estimate of credit losses. Non-performing loans totaling $6.6 million were sold during the third quarter of 2021 resulting in a net recoveries of $502,000.

At December 31, 2020, the Company reported an allowance for credit losses on available for sale securities of $2,000 and no allowance for credit losses on held to maturity securities. For the three months ended September 30, 2021, the Company recorded a provision for credit losses on available for sale securities of $32,000 and a provision for credit losses on held to maturity securities of $43,000. For the nine months ended September 30, 2021, the Company recorded a provision for credit losses of $51,000 and $180,000 on securities available for sale and held to maturity, respectively. The Company adopted ASU 2016-13 at December 31, 2020, and recorded an increase in the allowance for credit losses on held to maturity securities of $30,000 effective January 1, 2020. Prior year disclosures have not been restated. Accrued interest receivable on securities is reported as a component of accrued interest receivable on the consolidated balance sheets and totaled $4.6 million at September 30, 2021 and $3.3 million and December 31, 2020. The Company made the election to exclude accrued interest receivable from the estimate of credit losses on securities. Allowance for Credit Losses - Off-Balance-Sheet Exposures The allowance for credit losses on off-balance sheet exposures is reported in other liabilities in the Consolidated Balance Sheets. The liability represents an estimate of expected credit losses arising from off balance sheet exposures such as letters of credit, guarantees and unfunded loan commitments. The process for measuring lifetime expected credit losses on these exposures is consistent with that for loans as discussed above, but is subject to an additional estimate reflecting the likelihood that funding will occur. No liability is recognized for off balance sheet credit exposures that are unconditionally cancellable by the Company. Adjustments to the liability are reported as a component of the provision for credit losses. The Company adopted ASU 2016-13 at December 31, 2020, and recorded a decrease in the allowance for credit losses for off-balance-sheet exposures of $498,000 effective January 1, 2020. Prior year disclosures have not been restated. At September 30, 2021 and December 31, 2020, the balance of the allowance for credit losses for off-balance sheet exposures was $1.8 million and $2.6 million, respectively. The Company recorded a benefit for credit losses on off-balance-sheet exposures of $72,000 and $707,000 for the three and nine months ended September 30, 2021, respectively. In the third quarter of 2020, the Company recorded no provision for unfunded lending commitments and, for the nine months ended September 30, 2020, recorded $210,000 of provision for unfunded lending commitments in other noninterest expense.

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 2027. At September 30, 2021, the Company had lease liabilities totaling $16.1 million and right-of-use assets totaling $14.8 million related to these leases. At December 31, 2020, the Company had lease liabilities totaling $18.2 million and right-of-use assets totaling $16.8 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 the nine months ended September 30, 2021, the weighted average remaining lease term for operating leases was 9.54 years and the weighted average discount rate used in the measurement of operating lease liabilities was 3.46%. At December 31, 2020, the weighted average remaining lease term for operating leases was 9.69 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) 2021 2020 2021 2020 Operating lease cost $ 769 $ 828 $ 2,427 $ 2,484 Variable lease cost 22 22 67 87 Sublease income $ (30) $ (31) (91) (92) Net lease cost $ 761 $ 819 $ 2,403 $ 2,479 The table below presents other information on the Company's operating leases: Nine Months Ended September 30, (in thousands) 2021 2020 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 2,194 $ 2,085 Right-of-use asset obtained in exchange for new operating lease liabilities 109 741 There were no sale and leaseback transactions, leveraged leases or lease transactions with related parties during the nine months ended September 30, 2021 or September 30, 2020. At September 30, 2021, 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, 2021 are as follows: (in thousands) Within one year $ 2,956 After one year but within three years 5,081 After three years but within five years 3,792 After five years 7,423 Total undiscounted cash flows 19,252 Discount on cash flows (3,147) Total lease liability $ 16,105

Debt Disclosure [Abstract]
Borrowings	Borrowings Overnight and Short-Term Borrowings At September 30, 2021, the Company had no overnight and short-term borrowings from the FHLB, while these borrowings totaled $100.0 million at December 31, 2020. In addition, there were no overnight and short-term borrowings from correspondent banks at either September 30, 2021 or December 31, 2020. At September 30, 2021, Lakeland had overnight and short-term federal funds lines available to borrow up to $215.0 million from correspondent banks. Lakeland may also borrow from the discount window of the Federal Reserve Bank of New York based on the fair value of collateral pledged. Lakeland had no borrowings with the Federal Reserve Bank of New York as of September 30, 2021 or December 31, 2020. Other short-term borrowings at September 30, 2021 and December 31, 2020 consisted of short-term securities sold under agreements to repurchase of $111.9 million and $69.6 million, respectively. The securities sold under agreements to repurchase are overnight sweep arrangement accounts with our customers. As of September 30, 2021, the Company had $121.4 million in agency and mortgage-backed securities pledged for its securities sold under agreements to repurchase. At times, the fair 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. FHLB Advances The Company had one advance from the FHLB, which totaled $25.0 million at both September 30, 2021 and December 31, 2020, with a weighted average interest rate of 0.77% and maturity in 2025. The advance was collateralized by first mortgage loans and has 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. Subordinated Debentures On September 15, 2021, the Company completed an offering of $150.0 million of fixed to floating rate subordinated notes due on September 15, 2031. The notes bear interest at a rate of 2.875% per annum until September 15, 2026 and will then reset quarterly to the then current Benchmark rate (expected to be the three-month term Secured Overnight Financing Rate ("SOFR")) plus a spread of 220 basis points. The debt is included in Tier 2 capital for the Company. Debt issuance costs totaled $1.8 million and are being amortized to maturity. Subordinated debt is presented net of issuance costs on the consolidated balance sheets. On September 30, 2021, the Company redeemed $75.0 million of its 5.125% fixed to floating rate subordinated notes due September 30, 2026, which resulted in an acceleration of unamortized debt issuance costs of $831,000. In addition, the Company redeemed $5.0 million of subordinated notes in the second quarter of 2021.

Revenue Recognition

Revenue Recognition	9 Months Ended
	Sep. 30, 2021
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, 2021 and 2020: For the Three Months Ended September 30, For the Nine Months Ended September 30, (in thousands) 2021 2020 2021 2020 Service charges on deposit accounts: Debit card interchange income $ 1,585 $ 1,472 $ 4,603 $ 3,910 Overdraft charges 647 533 1,785 1,935 ATM service charges 182 138 497 367 Demand deposit fees and charges 107 129 348 394 Savings service charges 15 16 44 57 Total 2,536 2,288 7,277 6,663 Commissions and fees: Loan fees 376 510 1,367 1,063 Wire transfer charges 376 372 1,126 1,021 Investment services income 373 392 1,210 1,231 Merchant fees 270 184 729 598 Commissions from sales of checks 73 73 226 216 Safe deposit income 82 85 240 256 Other income 54 51 143 138 Total 1,604 1,667 5,041 4,523 Gains on sales of loans 550 1,437 1,865 2,562 Swap income — 624 634 4,234 Other Income: Title insurance income 43 46 87 126 Other income 99 200 262 370 Total 142 246 349 496 Revenue not from contracts with customers 637 511 1,331 1,787 Total Noninterest Income $ 5,469 $ 6,773 $ 16,497 $ 20,265 Timing of Revenue Recognition: Products and services transferred at a point in time 4,832 6,243 15,143 18,422 Products and services transferred over time — 19 23 56 Revenue not from contracts with customers 637 511 1,331 1,787 Total Noninterest Income $ 5,469 $ 6,773 $ 16,497 $ 20,265

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives Lakeland is a party to interest rate derivatives that are not designated as hedging instruments. 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 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 $60.5 million and $83.2 million in investment securities available for sale pledged for collateral on its interest rate swaps with financial institutions at September 30, 2021 and December 31, 2020, respectively. 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, 2021, the Company did not record any hedge ineffectiveness. The Company reclassified $8,000 and $58,000 of accumulated other comprehensive loss into interest expense for the third quarter of 2021 and 2020, respectively. The Company recognized $142,000 of accumulated other comprehensive loss that was reclassified into interest expense for the first nine months of 2021 and $17,000 of accumulated other comprehensive income that was reclassified into interest expense for same period in 2020. On June 30, 2021, $20.0 million in notional value of the swaps matured and on August 1, 2021, the remaining $10.0 million matured. Amounts reported in accumulated other comprehensive income related to derivatives were reclassified to interest expense as interest payments are made on the Company’s debt.

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, 2021 and December 31, 2020. 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. During the three and nine months ended September 30, 2021, there were no triggering events that would more likely than not reduce the fair value of our one reporting unit below its carrying amount. There was no impairment of goodwill recognized during the three and nine months ended September 30, 2021 and 2020. The Company had core deposit intangibles of $2.6 million and $3.3 million at September 30, 2021 and December 31, 2020, respectively. Amortization of core deposit intangible totaled $211,000 and $250,000 for the third quarters of 2021 and 2020, respectively, and $658,000 and $776,000 for the first nine months of 2021 and 2020, respectively.

Fair Value Measurement and Fair

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 investment securities available for sale, equity 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 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). Recurring Fair Value Measurements 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, 2021 and during 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, 2021 Assets: Investment securities, available for sale U.S. Treasury and government agencies $ 22,178 $ 80,793 $ — $ 102,971 Mortgage-backed securities, residential — 95,248 — 95,248 Collateralized mortgage obligations, residential — 200,900 — 200,900 Mortgage-backed securities, multifamily — 1,867 — 1,867 Collateralized mortgage obligations, multifamily — 35,003 — 35,003 Asset-backed securities — 54,007 — 54,007 Corporate bonds — 39,385 — 39,385 Total securities available for sale 22,178 507,203 — 529,381 Equity securities, at fair value — 16,422 — 16,422 Derivative assets — 50,014 — 50,014 Total Assets $ 22,178 $ 573,639 $ — $ 595,817 Liabilities: Derivative liabilities $ — $ 50,014 $ — $ 50,014 Total Liabilities $ — $ 50,014 $ — $ 50,014 December 31, 2020 Assets: Investment securities, available for sale U.S. Treasury and government agencies $ 9,392 $ 55,610 $ — $ 65,002 Mortgage-backed securities, residential — 228,156 — 228,156 Collateralized mortgage obligations, residential — 209,038 — 209,038 Mortgage-backed securities, multifamily — 1,944 — 1,944 Collateralized mortgage obligations, multifamily — 41,535 — 41,535 Asset-backed securities — 40,690 — 40,690 Obligations of states and political subdivisions — 233,710 — 233,710 Corporate bonds — 35,671 — 35,671 Total securities available for sale 9,392 846,354 — 855,746 Equity securities, at fair value — 14,694 — 14,694 Derivative assets — 80,734 — 80,734 Total Assets $ 9,392 $ 941,782 $ — $ 951,174 Liabilities: Derivative liabilities $ — $ 80,877 $ — $ 80,877 Total Liabilities $ — $ 80,877 $ — $ 80,877 Non-Recurring Fair Value Measurements 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 fair market value. Fair value is generally determined by the value of purchase commitments. Loans that do not have similar risk characteristics to the segments reported must be individually evaluated to determine an appropriate allowance. Management has identified criteria and procedures for identifying whether a loan should be individually evaluated for calculation of expected credit losses. If a loan is identified as meeting any of the criteria, it is deemed to have risk characteristics that are unique and will be separated from a pool. Those loans that are considered to have unique risk characteristics are then subjected to an individual allowance evaluation using either the fair value of the collateral, less estimated costs to sell, if collateral-dependent or the discounted cash flow method. 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 a recognized valuation resource. At September 30, 2021 and December 31, 2020, the Company had no OREO or other repossessed assets. 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. The following table summarized the Company’s financial assets that are measured at fair value 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, 2021 Assets: Individually evaluated loans $ — $ — $ 2,049 $ 2,049 December 31, 2020 Assets: Individually evaluated loans $ — $ — $ 2,417 $ 2,417 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, 2021 and December 31, 2020, 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. 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.
