Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles. The consolidated financial statements and the footnotes of First Guaranty Bancshares, Inc. ("First Guaranty") thereto should be read in conjunction with the audited consolidated financial statements and note disclosures for First Guaranty previously filed with the Securities and Exchange Commission in First Guaranty's Annual Report on Form 10-K for the year ended December 31, 2023. The consolidated financial statements include the accounts of First Guaranty Bancshares, Inc. and its wholly owned subsidiary First Guaranty Bank (the "Bank"). All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary for a fair presentation of the consolidated financial statements. Those adjustments are of a normal recurring nature. The results of operations at September 30, 2024 and for the three and nine month periods ended September 30, 2024 and 2023 are not necessarily indicative of the results expected for the full year or any other interim period. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for credit losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, and the valuation of investment securities.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Adopted in 2024 None. Accounting Pronouncements Not Yet Adopted ASU No. 2023-09, "Improvements to Tax Disclosures" ("ASU 2023-09") is intended to enhance the transparency and decision usefulness of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. This update is effective for annual periods beginning after December 15, 2024, though early adoption is permitted. We do not expect it to have a material effect on First Guaranty's consolidated financial statements.

The 139 securities had an aggregate amortized cost basis of $343.7 million and an unrealized loss of $57.2 million at September 30, 2024. Management has the intent and ability to hold these debt securities until maturity or until anticipated recovery. Securities are evaluated for impairment from credit losses at least quarterly and more frequently when economic or market conditions warrant such evaluation. Consideration is given to (i) the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, (iii) the recovery of contractual principal and interest and (iv) the intent and ability of First Guaranty to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Investment securities issued by the U.S. Government and Government sponsored enterprises with unrealized losses and the amount of unrealized losses on those investment securities that are the result of changes in market interest rates will not be credit impaired. First Guaranty has the ability and intent to hold these securities until recovery, which may not be until maturity. Corporate debt securities in a loss position consist primarily of corporate bonds issued by businesses in the financial, insurance, utility, manufacturing, industrial, consumer products and oil and gas industries. There was one held to maturity corporate security with a credit related impairment loss at September 30, 2024. First Guaranty believes that the remaining issuers will be able to fulfill the obligations of these securities based on evaluations described above. First Guaranty has the ability and intent to hold these securities until they recover, which could be at their maturity dates. There were no charge-offs recognized on securities during the nine months ended September 30, 2024 and 2023. There were no provisions for credit losses recognized on securities during the nine months ended September 30, 2024 and 2023. For securities that have indications of credit related impairment, management analyzes future expected cash flows to determine if any credit related impairment is evident. Estimated cash flows are determined using management's best estimate of future cash flows based on specific assumptions. The assumptions used to determine the cash flows were based on estimates of loss severity and credit default probabilities. Management reviews reports from credit rating agencies and public filings of issuers. At September 30, 2024, First Guaranty's exposure to bond issuers that exceeded 10% of shareholders' equity is below: At September 30, 2024 (in thousands) Amortized Cost Fair Value U.S. Government Treasuries (U.S.) $ 255,310 $ 255,231 Federal Home Loan Bank (FHLB) 32,275 27,355 Federal Home Loan Mortgage Corporation (Freddie Mac-FHLMC) 98,950 75,173 Federal Farm Credit Bank (FFCB) 139,099 115,843 Total $ 525,634 $ 473,602

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill and intangible assets deemed to have indefinite lives are no longer amortized but are subject to impairment testing. Other intangible assets continue to be amortized over their useful lives. First Guaranty's goodwill is the difference in purchase price over the fair value of net assets acquired from its acquisition of Homestead Bancorp in 2007, Premier Bancshares, Inc. in 2017 and Union Bancshares, Incorporated in 2019. Goodwill totaled $12.9 million at September 30, 2024 and December 31, 2023. No impairment charges have been recognized on First Guaranty's intangible assets since acquisition. Loan servicing assets totaled $0.4 million at September 30, 2024 and $0.5 million at December 31, 2023. Other intangible assets recorded include core deposit intangibles, which are subject to amortization. The weighted-average amortization period remaining for First Guaranty's core deposit intangibles is 4.5 years at September 30, 2024. The core deposits intangible reflect the value of deposit relationships, including the beneficial rates, which arose from acquisitions.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Off-balance sheet commitments First Guaranty is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit and standby and commercial letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of the involvement in particular classes of financial instruments. The exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby and commercial letters of credit is represented by the contractual notional amount of those instruments. The same credit policies are used in making commitments and conditional obligations as it does for balance sheet instruments. Unless otherwise noted, collateral or other security is not required to support financial instruments with credit risk. Below is a summary of the notional amounts of the financial instruments with off-balance sheet risk at September 30, 2024 and December 31, 2023: Contract Amount (in thousands) September 30, 2024 December 31, 2023 Commitments to Extend Credit $ 168,608 $ 304,218 Unfunded Commitments under lines of credit $ 183,222 $ 214,546 Commercial and Standby letters of credit $ 13,368 $ 13,971 Allowance For Credit Losses - Off- Balance-Sheet Credit Exposures The provision for credit losses on unfunded commitments was a reversal of $1.3 million for the nine months ended September 30, 2024. The ACL on off-balance-sheet credit exposures total $1.5 million at September 30, 2024 and $2.8 million at December 31, 2023 and is included in other liabilities on the accompanying consolidated balance sheets. Litigation First Guaranty is subject to various legal proceedings in the normal course of its business. First Guaranty assesses its liabilities and contingencies in connection with outstanding legal proceedings. Where it is probable that First Guaranty will incur a loss and the amount of the loss can be reasonably estimated, First Guaranty records a liability in its consolidated financial statements. First Guaranty does not record a loss if the loss is not probable or the amount of the loss is not estimable. First Guaranty Bank is a defendant in a lawsuit alleging fault for a loss of funds by a customer related to fraud by a third party with a possible loss range of $0.0 million to $1.5 million. The Bank denies the allegations and intends to vigorously defend against this lawsuit, which is in early stages and no trial date has been set. No accrued liability has been recorded related to this lawsuit. First Guaranty settled a case in the third quarter of 2021 for $1.1 million. A receivable for $0.9 million was recorded for recovery by a claim against First Guaranty's insurer. During the second quarter of 2024, First Guaranty received $0.5 million of the $0.9 million receivable. The remaining $0.4 million was written off. In the opinion of management, neither First Guaranty nor First Guaranty Bank is currently involved in such legal proceedings, either individually or in the aggregate, that the resolution is expected to have a material adverse effect on First Guaranty’s consolidated results of operations, financial condition, or cash flows. However, one or more unfavorable outcomes in these ordinary claims or litigation against First Guaranty or First Guaranty Bank could have a material adverse effect for the period in which they are resolved. In addition, regardless of their merits or ultimate outcomes, such matters are costly, divert management’s attention, and may materially and adversely affect the reputation of First Guaranty and First Guaranty Bank, even if resolved favorably.

Leases [Abstract]
Leases	Leases First Guaranty’s primary leasing activities relate to certain real estate leases of a portion of the main office, certain branches, and certain ATM locations. These leases have all been designated as operating leases. First Guaranty does not lease equipment under operating leases, and does not have leases designated as financing leases. On June 28, 2024 First Guaranty sold three properties owned by it, two stand-alone branches and a portion of the headquarters building which also contains a branch, to a partnership owned by certain directors of First Guaranty. The aggregate purchase price was approximately $14.7 million. All of the properties are located in Louisiana. First Guaranty concurrently entered into absolute net lease agreements with the partnership under which First Guaranty will lease each of the properties. Each of the lease agreements has an initial term of 15 years with specified renewal options. Annual payments due under the leases total approximately $1.3 million. The sale-leaseback transaction resulted in a pre-tax gain of approximately $13.3 million. First Guaranty recorded operating right-of-use ("ROU") assets and corresponding lease liabilities of $11.5 million and $11.5 million, respectively. Information concerning First Guaranty’s leases is as follows: Nine Months Ended Nine Months Ended Weighted-average lease term (in years) 14.5 4.8 Weighted-average discount rate 7.9 % 2.9 % First Guaranty’s operating lease ROU assets were $11.7 million and $0.3 million at September 30, 2024 and December 31, 2023, respectively, and the related operating lease liabilities were $11.8 million and $0.3 million, respectively. The ROU asset is included in Other Assets on the balance sheet, and the related operating lease liabilities are included in Other liabilities. Operating lease expense, including short-term leases, is included in occupancy expense in the amount of $0.6 million and $0.3 million for the nine months end September 30, 2024 and 2023, respectively. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Cash payment for amounts included in the measurement of lease liabilities of $0.4 million and $0.1 million were included in operating cash flows for the respective nine-month periods. The following table reports minimum lease payments under non-cancelable operating leases at September 30, 2024: (in thousands) Remainder of 2024 $ 352 2025 1,406 2026 1,406 2027 1,406 2028 1,351 Thereafter 13,519 Total lease payments 19,440 Less: interest (7,689) Present value of lease liabilities $ 11,751

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The fair value of a financial instrument is the current amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. Valuation techniques use certain inputs to arrive at fair value. Inputs to valuation techniques are the assumptions that market participants would use in pricing the asset or liability. They may be observable or unobservable. First Guaranty uses a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1 Inputs – Unadjusted quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds or credit risks) or inputs that are derived principally from or corroborated by market data by correlation or other means. Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. A description of the valuation methodologies used for instruments measured at fair value follows, as well as the classification of such instruments within the valuation hierarchy. Securities available for sale. Securities are classified within Level 1 where quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. If quoted market prices are unavailable, fair value is estimated using quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Securities classified within Level 3 in First Guaranty's portfolio as of September 30, 2024 includes corporate debt and municipal securities. Loan individually evaluated for impairment. Fair value is measured by either the fair value of the collateral if the loan is collateral dependent (Level 2 or Level 3), or the present value of expected future cash flows, discounted at the loan's effective interest rate (Level 3). Fair value of the collateral is determined by appraisals or by independent valuation. Other real estate owned. Properties are recorded at the balance of the loan or at estimated fair value less estimated selling costs, whichever is less, at the date acquired. Fair values of other real estate owned ("OREO") are determined by sales agreement or appraisal, and costs to sell are based on estimation per the terms and conditions of the sales agreement or amounts commonly used in real estate transactions. Inputs include appraisal values or recent sales activity for similar assets in the property's market; thus, OREO measured at fair value would be classified within either Level 2 or Level 3 of the hierarchy. Certain non-financial assets and non-financial liabilities are measured at fair value on a non-recurring basis including assets and liabilities related to reporting units measured at fair value in the testing of goodwill impairment, as well as intangible assets and other non-financial long-lived assets measured at fair value for impairment assessment. The following table summarizes financial assets measured at fair value on a recurring basis as of September 30, 2024 and December 31, 2023, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: (in thousands) September 30, 2024 December 31, 2023 Available for Sale Securities Fair Value Measurements Using: Level 1: Quoted Prices in Active Markets For Identical Assets $ 255,231 $ 49,830 Level 2: Significant Other Observable Inputs 77,328 23,172 Level 3: Significant Unobservable Inputs 10,039 10,483 Securities available for sale measured at fair value $ 342,598 $ 83,485 First Guaranty's valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While the methodologies used are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value. The change in Level 1 securities available for sale from December 31, 2023 to September 30, 2024 was due to a net increase in Treasury bills of $205.4 million. There were no transfers between Level 2 and Level 3 from December 31, 2023 to September 30, 2024. There were no transfers between Level 1 and 2 securities available for sale from December 31, 2023 to September 30, 2024. The following table reconciles assets measured at fair value on a recurring basis using unobservable inputs (Level 3) : Level 3 Changes (in thousands) September 30, 2024 Balance, beginning of year $ 10,483 Total gains or losses (realized/unrealized): Included in earnings — Included in other comprehensive income 79 Purchases, sales, issuances and settlements, net (523) Transfers in and/or out of Level 3 — Balance as of end of period $ 10,039 There were no gains or losses for the period included in earnings attributable to the change in unrealized gains or losses related to assets still held as of September 30, 2024.

Investments, All Other Investments [Abstract]
Financial Instruments	Financial Instruments Fair value estimates are generally subjective in nature and are dependent upon a number of significant assumptions associated with each instrument or group of similar instruments, including estimates of discount rates, risks associated with specific financial instruments, estimates of future cash flows and relevant available market information. Fair value information is intended to represent an estimate of an amount at which a financial instrument could be exchanged in a current transaction between a willing buyer and seller engaging in an exchange transaction. However, since there are no established trading markets for a significant portion of First Guaranty's financial instruments, First Guaranty may not be able to immediately settle financial instruments; as such, the fair values are not necessarily indicative of the amounts that could be realized through immediate settlement. In addition, the majority of the financial instruments, such as loans and deposits, are held to maturity and are realized or paid according to the contractual agreement with the customer. Quoted market prices are used to estimate fair values when available. However, due to the nature of the financial instruments, in many instances quoted market prices are not available. Accordingly, estimated fair values have been estimated based on other valuation techniques, such as discounting estimated future cash flows using a rate commensurate with the risks involved or other acceptable methods. Fair values are estimated without regard to any premium or discount that may result from concentrations of ownership of financial instruments, possible income tax ramifications or estimated transaction costs. The fair value estimates are subjective in nature and involve matters of significant judgment and, therefore, cannot be determined with precision. Fair values are also estimated at a specific point in time and are based on interest rates and other assumptions at that date. As events change the assumptions underlying these estimates, the fair values of financial instruments will change. Disclosure of fair values is not required for certain items such as lease financing, investments accounted for under the equity method of accounting, obligations of pension and other postretirement benefits, premises and equipment, other real estate, prepaid expenses, the value of long-term relationships with depositors (core deposit intangibles) and other customer relationships, other intangible assets and income tax assets and liabilities. Fair value estimates are presented for existing on- and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses have not been considered in the estimates. Accordingly, the aggregate fair value amounts presented do not purport to represent and should not be considered representative of the underlying market or franchise value of First Guaranty. Because the standard permits many alternative calculation techniques and because numerous assumptions have been used to estimate the fair values, reasonable comparison of the fair value information with other financial institutions' fair value information cannot necessarily be made. The methods and assumptions used to estimate the fair values of financial instruments are as follows: Cash and due from banks, interest-bearing deposits with banks, federal funds sold and federal funds purchased. These items are generally short-term and the carrying amounts reported in the consolidated balance sheets are a reasonable estimation of the fair values. Investment Securities. Fair values are principally based on quoted market prices. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments or the use of discounted cash flow analyses. Loans Held for Sale. Fair values of mortgage loans held for sale are based on commitments on hand from investors or prevailing market prices. These loans are classified within level 3 of the fair value hierarchy. Loans, net. Market values are computed present values using net present value formulas. The present value is the sum of the present value of all projected cash flows on an item at a specified discount rate. The discount rate is set as an appropriate rate index, plus or minus an appropriate spread. These loans are classified within level 3 of the fair value hierarchy. Loan individually evaluated for impairment. Fair value is measured by either the fair value of the collateral if the loan is collateral dependent (Level 2 or Level 3), or the present value of expected future cash flows, discounted at the loan's effective interest rate (Level 3). Fair value of the collateral is determined by appraisals or by independent valuation. Cash Surrender of BOLI. The cash surrender value of BOLI approximates fair value. Accrued interest receivable. The carrying amount of accrued interest receivable approximates its fair value. Deposits. The fair value of customer deposits, excluding certificates of deposit, is the amount payable on demand. Market values of certificates of deposit are actually computed present values using net present value formulas. The present value is the sum of the present value of all projected cash flows on an item at a specified discount rate. The discount rate is set as an appropriate rate index, plus or minus an appropriate spread. Deposits are classified within level 3 of the fair value hierarchy. Accrued interest payable. The carrying amount of accrued interest payable approximates its fair value. Borrowings. The carrying amount of federal funds purchased and other short-term borrowings approximate their fair values. The fair value of First Guaranty's long-term borrowings is computed using net present value formulas. The present value is the sum of the present value of all projected cash flows on an item at a specified discount rate. The discount rate is set as an appropriate rate index, plus or minus an appropriate spread. Borrowings are classified within level 3 of the fair value hierarchy. Other Unrecognized Financial Instruments. The fair value of commitments to extend credit is estimated using the fees charged to enter into similar legally binding agreements, taking into account the remaining terms of the agreements and customers' credit ratings. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair values of letters of credit are based on fees charged for similar agreements or on estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date. At September 30, 2024 and December 31, 2023, the fair value of guarantees under commercial and standby letters of credit was not material. The carrying amounts and estimated fair values of financial instruments at September 30, 2024 were as follows: Fair Value Measurements at September 30, 2024 Using (in thousands) Carrying Amount Level 1 Level 2 Level 3 Total Assets Cash and due from banks $ 362,855 $ 362,855 $ — $ — $ 362,855 Federal funds sold 4,766 4,766 — — 4,766 Securities, available for sale 342,598 255,231 77,328 10,039 342,598 Securities, held for maturity 321,428 — 265,540 — 265,540 Loans held for sale — — — — — Loans, net 2,736,370 — — 2,612,913 2,612,913 Cash surrender value of BOLI 5,973 — — 5,973 5,973 Accrued interest receivable 17,660 — — 17,660 17,660 Liabilities Deposits $ 3,429,925 $ — $ — $ 3,439,377 3,439,377 Short-term advances from Federal Home Loan Bank — — — Short-term borrowings — — — — — Repurchase agreements 6,981 — — 7,031 7,031 Accrued interest payable 17,750 — — 17,750 17,750 Long-term advances from Federal Home Loan Bank 135,000 — — 137,374 137,374 Senior long-term debt 16,163 — — 16,281 16,281 Junior subordinated debentures 44,730 — — 44,730 44,730 The carrying amounts and estimated fair values of financial instruments at December 31, 2023 were as follows: Fair Value Measurements at December 31, 2023 Using (in thousands) Carrying Amount Level 1 Level 2 Level 3 Total Assets Cash and due from banks $ 286,114 $ 286,114 $ — $ — $ 286,114 Federal funds sold 341 341 — — 341 Securities, available for sale 83,485 49,830 23,172 10,483 83,485 Securities, held for maturity 320,638 — 253,584 — 253,584 Loans, net 2,717,782 — — 2,581,979 2,581,979 Cash surrender value of BOLI 5,861 — — 5,861 5,861 Accrued interest receivable 15,713 — — 15,713 15,713 Liabilities Deposits $ 3,009,094 $ — $ — $ 3,001,498 3,001,498 Short-term advances from Federal Home Loan Bank 50,000 — — 50,000 50,000 Short-term borrowings 10,000 — — 10,000 10,000 Repurchase agreements 6,297 — — 6,285 6,285 Accrued interest payable 11,807 — — 11,807 11,807 Long-term advances from Federal Home Loan Bank 155,000 — — 152,299 152,299 Senior long-term debt 39,099 — — 39,304 39,304 Junior subordinated debentures 15,000 — — 15,000 15,000 There is no material difference between the contract amount and the estimated fair value of off-balance sheet items that are primarily comprised of short-term unfunded loan commitments that are generally at market prices.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles. The consolidated financial statements and the footnotes of First Guaranty Bancshares, Inc. ("First Guaranty") thereto should be read in conjunction with the audited consolidated financial statements and note disclosures for First Guaranty previously filed with the Securities and Exchange Commission in First Guaranty's Annual Report on Form 10-K for the year ended December 31, 2023. The consolidated financial statements include the accounts of First Guaranty Bancshares, Inc. and its wholly owned subsidiary First Guaranty Bank (the "Bank"). All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary for a fair presentation of the consolidated financial statements. Those adjustments are of a normal recurring nature. The results of operations at September 30, 2024 and for the three and nine month periods ended September 30, 2024 and 2023 are not necessarily indicative of the results expected for the full year or any other interim period. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for credit losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, and the valuation of investment securities.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Adopted in 2024 None. Accounting Pronouncements Not Yet Adopted ASU No. 2023-09, "Improvements to Tax Disclosures" ("ASU 2023-09") is intended to enhance the transparency and decision usefulness of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. This update is effective for annual periods beginning after December 15, 2024, though early adoption is permitted. We do not expect it to have a material effect on First Guaranty's consolidated financial statements.
Fair Value Measurements	Fair Value Measurements The fair value of a financial instrument is the current amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. Valuation techniques use certain inputs to arrive at fair value. Inputs to valuation techniques are the assumptions that market participants would use in pricing the asset or liability. They may be observable or unobservable. First Guaranty uses a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1 Inputs – Unadjusted quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds or credit risks) or inputs that are derived principally from or corroborated by market data by correlation or other means. Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. A description of the valuation methodologies used for instruments measured at fair value follows, as well as the classification of such instruments within the valuation hierarchy. Securities available for sale. Securities are classified within Level 1 where quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. If quoted market prices are unavailable, fair value is estimated using quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Securities classified within Level 3 in First Guaranty's portfolio as of September 30, 2024 includes corporate debt and municipal securities. Loan individually evaluated for impairment. Fair value is measured by either the fair value of the collateral if the loan is collateral dependent (Level 2 or Level 3), or the present value of expected future cash flows, discounted at the loan's effective interest rate (Level 3). Fair value of the collateral is determined by appraisals or by independent valuation. Other real estate owned. Properties are recorded at the balance of the loan or at estimated fair value less estimated selling costs, whichever is less, at the date acquired. Fair values of other real estate owned ("OREO") are determined by sales agreement or appraisal, and costs to sell are based on estimation per the terms and conditions of the sales agreement or amounts commonly used in real estate transactions. Inputs include appraisal values or recent sales activity for similar assets in the property's market; thus, OREO measured at fair value would be classified within either Level 2 or Level 3 of the hierarchy. Certain non-financial assets and non-financial liabilities are measured at fair value on a non-recurring basis including assets and liabilities related to reporting units measured at fair value in the testing of goodwill impairment, as well as intangible assets and other non-financial long-lived assets measured at fair value for impairment assessment. ASC 825-10 provides First Guaranty with an option to report selected financial assets and liabilities at fair value. The fair value option established by this statement permits First Guaranty to choose to measure eligible items at fair value at specified election dates and report unrealized gains and losses on items for which the fair value option has been elected in earnings at each reporting date subsequent to implementation. First Guaranty has chosen not to elect the fair value option for any items that are not already required to be measured at fair value in accordance with accounting principles generally accepted in the United States.
