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.</font></div><div style="line-height:120%;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;">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.</font></div><div style="line-height:120%;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;">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.</font></div><div style="line-height:120%;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;">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.</font></div><div style="line-height:120%;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;">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 adopted this ASU in the third quarter of 2018 and reclassified its stranded tax credit of </font><font style="font-family:inherit;font-size:9pt;">$306,000</font><font style="font-family:inherit;font-size:9pt;"> from accumulated other comprehensive income to retained earnings. </font></div><div style="line-height:120%;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;">In August 2018, the FASB issued ASU No. 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." This ASU removes, modifies, and adds certain disclosure requirements for fair value measurements. For example, public entities will no longer be required to disclose the valuation processes for Level 3 fair value measurements, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. This ASU is effective for interim and annual reporting periods beginning after December 15, 2019. In addition, entities may early adopt the modified or eliminated disclosure requirements and delay adoption of the additional disclosure requirements until their effective date. First Guaranty does not believe the adoption of this ASU will have a material impact on the Consolidated Financial Statements, as the update only revises disclosure requirements.</font></div></div>

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. In connection with the determination of the allowance for loan losses and real estate owned, First Guaranty obtains independent appraisals for significant properties.</font></div></div>
