Basis of Presentation [Abstract]
Basis of Presentation	Note 1. 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, 2017. 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 March 31, 2018 and for the three month periods ended March 31, 2018 and 2017 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 loan 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 [Abstract]
Recent Accounting Pronouncements	Note 2. Recent Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, "Leases: Conforming Amendments Related to Leases". This ASU amends the codification regarding leases in order to increase transparency and comparability. The ASU requires companies to recognize lease assets and liabilities on the balance sheet and disclose key information about leasing arrangements. A lessee would recognize a liability to make lease payments and a right-of-use asset representing its right to use the leased asset for the lease term. The ASU is effective for annual and interim periods beginning after December 15, 2018. The adoption of this ASU is not expected to have a material effect on First Guaranty's Consolidated Financial Statements. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments- Credit Losses: Measurement of Credit Losses on Financial Instruments". This ASU amends guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. The ASU amendments require the measurement of all expected credit losses for financial assets held at the reporting date be based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU requires assets held at cost basis to reflect the company's current estimate of all expected credit losses. For available for sale debt securities, credit losses should be presented as an allowance rather than as a write-down. In addition, this ASU amends the accounting for purchased financial assets with credit deterioration. This ASU is effective for annual and interim periods beginning after December 15, 2019. First Guaranty is currently evaluating the impact of this accounting standard and is implementing a new software application to assist in determining the impact on the Consolidated Financial Statements. In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment". This ASU amends the guidance on impairment testing. The ASU eliminates Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The ASU also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU is effective for annual and interim periods beginning after December 15, 2019. First Guaranty is currently evaluating the impact of the adoption of this guidance on the Consolidated Financial Statements. In March 2017, the FASB issued ASU 2017-08, "Receivables- Nonrefundable Fees and Other Costs, Premium Amortization on Purchased Callable Debt Securities". This ASU shortens the amortization period for certain callable debt securities held at a premium. Specifically, this ASU requires the premium to be amortized to the earliest call date. This ASU does not require an accounting change for securities held at a discount, the discount continues to be amortized to maturity. This ASU is effective for annual and interim periods beginning after December 15, 2018. First Guaranty is currently evaluating the impact of the adoption of this guidance on the Consolidated Financial Statements. In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income". This ASU provides an option to reclassify stranded tax effects within AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (or portion thereof) is recorded. This ASU requires disclosure of a description of the accounting policy for releasing income tax effects from AOCI; whether election is made to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act; and information about the other income tax effects that are reclassified. This ASU is effective for annual and interim periods beginning after December 15, 2018. First Guaranty is currently evaluating the impact of the adoption of this guidance on the Consolidated Financial Statements.

Merger Transaction [Abstract]
Merger Transaction	Note 3. Merger Transaction Effective at the close of business on June 16, 2017, First Guaranty completed its acquisition of 100% of the outstanding shares of Premier Bancshares, Inc., a Texas corporation ("Premier"), a single bank holding company headquartered in McKinney, Texas and its wholly owned subsidiary, Synergy Bank. This acquisition allowed First Guaranty to expand its presence into the North Central Texas market area. Under terms of an agreement and plan of merger dated January 30, 2017, First Guaranty issued 0.119 of a sh 397,988 21.0 The valuations of loans, premises and equipment and core deposit intangible and other assets acquired and liabilities assumed are still preliminary and subject to change. United States generally accepted accounting principles ("U.S. GAAP") provides up to twelve months following the date of acquisition in which management can finalize the fair values of acquired assets and assumed liabilities. Material events that occur during the measurement period will be analyzed to determine if the new information reflected facts and circumstances that existed on the acquisition date. The measurement period ends as soon as First Guaranty receives the information it was seeking about facts and circumstances that existed as of the acquisition date or learns more information is unobtainable. The measurement period is limited to one year from the acquisition date. Once management has finalized the fair values of acquired assets and assumed liabilities within this twelve month period, management considers such values to be the "Day One Fair Values." No adjustments were made in the first quarter of 2018 to the fair value estimates. Based on management's preliminary valuation of the fair value of tangible and intangible assets acquired and liabilities assumed, the purchase price for the Premier acquisition is allocated in the table below.

The 145 securities had an aggregate amortized cost basis of $223.5 million and an unrealized loss of $9.7 million at March 31, 2018. Management has the intent and ability to hold these debt securities until maturity or until anticipated recovery. Securities are evaluated for other-than-temporary impairment at least quarterly and more frequently when economic or market conditions warrant such evaluation. Consideration is given to (i) the length of time and 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 other-than-temporarily 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. Two securities with an other-than-temporary impairment loss were held at March 31, 2018. 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 other-than-temporary impairment losses recognized on securities during the three months ended March 31, 2018 and 2017. The following table presents a roll-forward of the amount of credit losses on debt securities held by First Guaranty for which a portion of OTTI was recognized in other comprehensive income for the three months ended March 31, 2018 and 2017: (in thousands) Three Months Ended March 31, 2018 Three Months Ended March 31, 2017 Beginning balance of credit losses at end of prior year $ 60 $ 60 Other-than-temporary impairment credit losses on securities not previously OTTI - - Increases for additional credit losses on securities previously determined to be OTTI - - Reduction for increases in cash flows - - Reduction due to credit impaired securities sold or fully settled - - Ending balance of cumulative credit losses recognized in earnings at end of period $ 60 $ 60 In the first three months of 2018 there were no other-than-temporary impairment credit losses on securities for which we had previously recognized OTTI. 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 March 31, 2018, First Guaranty's exposure to bond issuers that exceeded 10% of shareholders' equity is below: At March 31, 2018 (in thousands) Amortized Cost Fair Value U.S. Treasuries $ 15,296 $ 15,296 Federal Home Loan Bank (FHLB) 50,396 48,473 Federal Home Loan Mortgage Corporation (Freddie Mac-FHLMC) 63,363 62,020 Federal National Mortgage Association (Fannie Mae-FNMA) 113,514 109,654 Federal Farm Credit Bank (FFCB) 136,925 131,963 Total $ 379,494 $ 367,406

The carrying amount of those loans is as follows at March 31, 2018. thousands) As of March 31, 2018 As of December 31, 2017 Real Estate: Construction & land development $ 1,127 $ 1,135 Farmland 7 8 1 - 4 family 48 50 Multifamily - - Non-farm non-residential 2,131 2,148 Total Real Estate 3,313 3,341 Non-Real Estate: Agricultural - - Commercial and industrial 896 1,017 Consumer and other - - Total Non-Real Estate 896 1,017 Total $ 4,209 $ 4,358 For those purchased loans disclosed above, there was no allowance for loan losses at March 31, 2018 or December 31, 2017. Where First Guaranty can reasonably estimate the cash flows expected to be collected on the loans, a portion of the purchase discount is allocated to an accretable yield adjustment based upon the present value of the future estimated cash flows versus the current carrying value of the loan and the accretable yield portion is being recognized as interest income over the remaining life of the loan. Where First Guaranty cannot reasonably estimate the cash flows expected to be collected on the loans, it has decided to account for those loans using the cost recovery method of income recognition. As such, no portion of a purchase discount adjustment has been determined to meet the definition of an accretable yield adjustment on those loans accounted for using the cost recovery method. If, in the future, cash flows from the borrower(s) can be reasonably estimated, a portion of the purchase discount would be allocated to an accretable yield adjustment based upon the present value of the future estimated cash flows versus the current carrying value of the loan and the accretable yield portion would be recognized as interest income over the remaining life of the loan. Until such accretable yield can be calculated, under the cost recovery method of income recognition, all payments will be used to reduce the carrying value of the loan and no income will be recognized on the loan until the carrying value is reduced to zero. Any loan accounted for under the cost recovery method is also still included as a non-accrual loan in the amounts presented in the table below. The accretable yield, or income expected to be collected, on the purchased loans above is as follows for the three months ended March 31, 2018.

Payment status, collateral value and the probability of collecting scheduled principal and interest payments when due are considered in evaluating loan impairment. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired.

The modifications to First Guaranty's TDRs were concessions on either the interest rate charged or the amortization. The effect of the modifications to First Guaranty was a reduction in interest income. These loans have an allocated reserve in First Guaranty's allowance for loan losses. First Guaranty has not restructured any loans that are considered TDRs in the three months ended March 31, 2018.

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 and Premier in 2017. Goodwill totaled $3.5 million at March 31, 2018 and December 31, 2017. No impairment charges have been recognized on First Guaranty's intangible assets.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 9. 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 March 31, 2018 and December 31, 2017: Contract Amount (in thousands) March 31, 2018 December 31, 2017 Commitments to Extend Credit $ 65,638 $ 78,125 Unfunded Commitments under lines of credit $ 126,401 $ 101,344 Commercial and Standby letters of credit $ 8,801 $ 7,886 Litigation The nature of First Guaranty's business ordinarily results in a certain amount of claims, litigation and legal and administrative cases, all of which are considered incidental to the normal conduct of business. When First Guaranty determines it has defenses to the claims asserted, it defends itself. First Guaranty will consider settlement of cases when it is in the best interests of both First Guaranty and its shareholders. While the final outcome of legal proceedings is inherently uncertain, based on information currently available as of March 31, 2018, any incremental liability arising from First Guaranty's legal proceedings will not have a material adverse effect on First Guaranty's financial position or results of operations.

Fair Value Measurements

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 10. 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 Level 2 Inputs Level 3 Inputs 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. Impaired loans. Other real estate owned. 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 March 31, 2018 and December 31, 2017, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: (in thousands) March 31, 2018 December 31, 2017 Available for Sale Securities Fair Value Measurements Using: Level 1: Quoted Prices in Active Markets For Identical Assets $ 15,781 $ 19,980 Level 2: Significant Other Observable Inputs 362,507 355,022 Level 3: Significant Unobservable Inputs 6,683 6,533 Securities available for sale measured at fair value $ 384,971 $ 381,535 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, 2017 to March 31, 2018 was due principally to a net decrease in Treasury bills of $4.2 million. The change in Level 2 securities available for sale from December 31, 2017 to March 31, 2018 was due principally to the purchase of mortgage-backed securities. The following table measures financial assets and financial liabilities measured at fair value on a non-recurring basis as of March 31, 2018 and December 31, 2017, segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value: (in thousands) At March 31, 2018 At December 31, 2017 Impaired Loans - Fair Value Measurements Using: Level 1: Quoted Prices in Active Markets For Identical Assets $ - $ - Level 2: Significant Other Observable Inputs - - Level 3: Significant Unobservable Inputs 9,470 12,003 Impaired loans measured at fair value $ 9,470 $ 12,003 Other Real Estate Owned - Fair Value Measurements Using: Level 1: Quoted Prices in Active Markets For Identical Assets $ - $ - Level 2: Significant Other Observable Inputs 1,239 1,249 Level 3: Significant Unobservable Inputs 32 32 Other real estate owned measured at fair value $ 1,271 $ 1,281 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.

Financial Instruments

Financial Instruments [Abstract]
Financial Instruments	Note 11. 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. Impaired loans. Fair value of impaired loans 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. Accrued interest receivable. The carrying amount of accrued interest receivable approximates its fair value. Deposits. The fair value of demand deposits, savings and interest-bearing demand deposits is the amount payable on demand. The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining maturities. 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. Noninterest-bearing deposits are held at cost. 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 March 31, 2018 and December 31, 2017 the fair value of guarantees under commercial and standby letters of credit was not material. The estimated fair values and carrying values of the financial instruments at March 31, 2018 and December 31, 2017 are presented in the following table: March 31, 2018 December 31, 2017 (in thousands) Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Assets Cash and cash equivalents $ 32,264 $ 32,264 $ 38,028 $ 38,028 Securities, available for sale 384,971 384,971 381,535 381,535 Securities, held to maturity 117,111 113,348 120,121 118,557 Federal Home Loan Bank stock 2,359 2,359 2,351 2,351 Loans held for sale 1,837 2,021 1,308 1,439 Loans, net 1,127,383 1,115,592 1,139,789 1,133,868 Accrued interest receivable 8,098 8,098 7,982 7,982 Liabilities Deposits $ 1,550,230 $ 1,546,546 $ 1,549,286 $ 1,549,449 Borrowings 22,040 22,058 38,274 38,294 Junior subordinated debentures 14,673 14,525 14,664 14,324 Accrued interest payable 2,849 2,849 2,488 2,488 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.

Basis of Presentation [Abstract]
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, 2017. 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 March 31, 2018 and for the three month periods ended March 31, 2018 and 2017 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 loan 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 [Abstract]
Recent Accounting Pronouncements	In February 2016, the FASB issued ASU 2016-02, "Leases: Conforming Amendments Related to Leases". This ASU amends the codification regarding leases in order to increase transparency and comparability. The ASU requires companies to recognize lease assets and liabilities on the balance sheet and disclose key information about leasing arrangements. A lessee would recognize a liability to make lease payments and a right-of-use asset representing its right to use the leased asset for the lease term. The ASU is effective for annual and interim periods beginning after December 15, 2018. The adoption of this ASU is not expected to have a material effect on First Guaranty's Consolidated Financial Statements.
