Debt securities are classified as held to maturity and carried at amortized cost, excluding accrued interest, when management has the positive intent and ability to hold them to maturity. Debt securities are classified as available-for-sale when they might be sold before maturity. Available-for-sale debt securities are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of applicable taxes. Beginning January 1, 2020, unrealized

losses resulting from credit losses for available-for-sale debt securities are recognized in earnings as a provision for credit losses. Unrealized losses that do not result from credit losses are excluded from earnings and reported as accumulated other comprehensive income, net of applicable taxes, which is included in equity. Accrued interest receivable is separated from other components of amortized cost and presented separately on the consolidated balance sheets.

Equity securities with readily determinable market values are carried at fair value on the balance sheet with any periodic changes in value made through adjustments to the statement of income. Equity securities without readily determinable market values are carried at cost less impairment and included in other assets on the consolidated balance sheets.

Interest income includes the amortization and accretion of purchase premium and discount. Premiums and discounts on securities are amortized on the level-yield method anticipating prepayments based upon the prior three month average monthly prepayments when available. Gains and losses on sales are recorded on the trade date and determined using the specific identification method.

The Company evaluates available-for-sale securities for expected credit losses at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. For securities in an unrealized loss position, consideration is given to the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. In analyzing an issuer’s financial condition, the Company considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition.

When credit losses are expected to occur, the amount of the expected credit loss recognized in earnings depends on the Company's intention to sell the security or if it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, the expected credit loss recognized in earnings is equal to the entire difference between its amortized cost basis and its fair value at the date it was determined to be impaired due to credit losses or other factors. The previous amortized cost basis less the impairment recognized in earnings becomes the new amortized cost basis of the investment.

However, if the Company does not intend to sell the security and it is not more likely than not to be required to sell the security before recovery of its amortized cost basis, the difference between the amortized cost and the fair value is separated into the amount representing the credit loss and the amount related to all other factors. If the Company determines a decline in fair value below the amortized cost basis of an available-for-sale investment security has resulted from credit related factors, beginning January 1, 2020 with the adoption of CECL, the Company records a credit loss through an allowance for credit losses. The allowance for credit losses is limited by the amount that the fair value is less than amortized cost. The amount of the allowance for credit losses is determined based on the present value of cash flows expected to be collected and is recognized as a charge to earnings. The amount of the impairment related to other, non-credit related, factors is recognized in other comprehensive income, net of applicable taxes.

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are stated at the principal amount outstanding less any purchase accounting discount net of any accretion recognized to date. Interest on loans is recognized as income by using the simple interest method on daily balances of the principal amount outstanding plus any accretion of purchase accounting discounts. Accrued interest receivable is separated from other components of amortized cost and presented separately on the consolidated balance sheets.

Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. Accrual of interest is discontinued on loans past due 90 days or more unless the credit is well secured and in the process of collection. Also, a loan may be placed on nonaccrual status prior to becoming past due 90 days if management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that collection of principal or interest is doubtful. The decision to place a loan on nonaccrual status prior to becoming past due 90 days is based on an evaluation of the borrower’s financial condition, collateral liquidation value, economic and business conditions and other factors that affect the borrower’s ability to pay. When a loan is placed on nonaccrual status, the accrued but unpaid interest is charged against current period operations through a reversal of interest income. Thereafter,

interest on nonaccrual loans is recognized only as received if future collection of principal is probable. If the collectibility of outstanding principal is doubtful, interest received is applied as a reduction of principal. A loan may be restored to accrual status when principal and interest are no longer past due or it otherwise becomes both well secured and collectability is reasonably assured. The nonaccrual policy results in timely reversal of accrued interest receivable, so an allowance for credit losses is not required on accrued interest receivable.

The allowance for credit losses represents the portion of the loan's amortized cost basis that the Company does not expect to collect due to credit losses over the loan's life, considering past events, current conditions, and reasonable and supportable forecasts of future economic conditions considering macroeconomic forecasts. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for credit losses is based on the loan's amortized cost basis, excluding accrued interest receivable, as the Company promptly charges off uncollectible accrued interest receivable. Management’s determination of the appropriateness of the allowance is based on periodic evaluation of the loan portfolio, lending-related commitments and other relevant factors, including macroeconomic forecasts and historical loss rates. In future quarters, the Company may update information and forecasts that may cause significant changes in the estimate in those future quarters.

As of January 1, 2020, the Company’s policy for the allowance for credit losses changed with the adoption of CECL. As permitted, the new guidance was implemented using a modified retrospective approach with the impact of the initial adoption being recorded through retained earnings at January 1, 2020, with no restatement of prior periods. Prior to adopting CECL, the Company calculated the allowance using an incurred loss approach. Beginning January 1, 2020, the Company calculates the allowance using a lifetime expected credit loss approach as described in the previous paragraph. See Note 4 for additional details related to the Company's specific calculation methodology.

The allowance for credit losses is the Company’s best estimate. Actual losses may differ from the June 30, 2020 allowance for credit loss as the CECL estimate is sensitive to economic forecasts and management judgment. There have been no changes to portfolio segments as described in the accounting policies within the Company's Annual Report on Form 10-K.

Business combinations are accounted for by applying the acquisition method in accordance with Accounting Standards Codification ("ASC") 805, “Business Combinations” (“ASC 805”). Under the acquisition method, identifiable assets acquired and liabilities assumed and any non-controlling interest in the acquiree at the acquisition date are measured at their fair values as of that date. Any excess of the purchase price over fair value of net assets acquired is recorded as goodwill. To the extent the fair value of net assets acquired, including any other identifiable intangible assets, exceed the purchase price, a bargain purchase gain is recognized. Results of operations of acquired entities are included in the consolidated statements of income from the date of acquisition.

Beginning January 1, 2020, loans acquired in business combinations with evidence of more-than-insignificant credit deterioration since origination are considered to be Purchased Credit Deteriorated ("PCD"). The Company developed multiple criteria to assess the presence of more–than–insignificant credit deterioration in acquired loans, mainly focused on changes in credit quality and payment status. While general criteria have been established, each acquisition will vary in its specific facts and circumstances and the Company will apply judgment around PCD identification for each individual acquisition based on their unique portfolio mix and risks identified.

The Company adopted ASC 326 using the prospective transition approach for loans previously classified as purchased credit impaired ("PCI") and accounted for under ASC 310-30. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption and all PCI loans were transitioned to PCD loans upon adoption. Under PCD accounting,the amount of expected credit losses as of the acquisition date is added to the purchase price of the PCD loan. This establishes the amortized cost basis of the PCD loan. The difference between the unpaid principal balance of the PCD loan and the amortized cost basis of the PCD loan as of the acquisition date is the non-credit discount. Interest income for a PCD loan is recognized by accreting the amortized cost basis of the PCD loan to its contractual cash flows. The discount related to estimated credit losses on acquisition recorded as an allowance for credit losses will not be accreted into interest income. Only the noncredit-related discount will be accreted into interest income and subsequent adjustments to expected credit losses will flow through the provision for credit losses on the income statement.

Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded, unless considered derivatives.

For loan commitments that are not accounted for as derivatives and when the obligation is not unconditionally cancelable by the Company, the Company applies the CECL methodology to estimate the expected credit loss on off-balance-sheet commitments. The estimate of expected credit losses for off-balance-sheet credit commitments is recognized as a liability. When the loan is funded, an allowance for expected credit losses is estimated for that loan using the CECL methodology, and the liability for off-balance-sheet commitments is reduced. When applying the CECL methodology to estimate the expected credit loss, the Company considers the likelihood that funding will occur, the contractual period of exposure to credit loss, the risk of loss, historical loss experience, and current conditions along with expectations of future economic conditions.

In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 and its subsequent amendments issued by the FASB, which requires the measurement of all current expected credit losses for financial assets (including off-balance sheet credit exposures) held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Additionally, the update requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. The new methodology requires institutions to calculate all probable and estimable losses that are expected to be incurred through the financial asset's entire life through a provision for credit losses, including certain loans obtained as a result of any acquisition. For available-for-sale debt securities that have experienced a deterioration in credit, Topic 326 requires an allowance for credit losses to be recognized, instead of a direct write-down, which was previously required under the other-than-temporary impairment ("OTTI") model. Topic 326 eliminates the concept of “other-than-temporary” impairment and instead focuses on determining whether any impairment is a result of a credit loss or other factors. As a result, the standard says the Company may not use the length of time a debt security has been in an unrealized loss position as a factor, either by itself or in combination with other factors, to conclude that a credit loss does not exist, as the Company was previously allowed under the OTTI model.

ASU 2016-13 eliminates the existing guidance for PCI loans, but requires an allowance for purchased financial assets with more than insignificant deterioration since origination to be determined in a manner similar to that of other financial assets measured at amortized cost; however, the initial allowance will be added to the purchase price rather than recorded as provision expense referred herein as the PCD asset gross-up approach. The Company applied the new PCD asset gross-up approach at transition to all assets that were accounted for as PCI prior to adoption. Any change in the allowance for credit losses for these assets as a result of applying the new guidance is accounted for as an adjustment to the asset’s amortized cost basis and not as a cumulative-effect adjustment to beginning retained earnings. Additionally, ASU 2016-13 requires additional disclosures related to loans and debt securities. See Note 3, “Investment securities” and Note 4, “Loans and allowance for credit losses” for these disclosures.

The Company formed a cross–functional working group to oversee the adoption of CECL at the effective date. The working group developed a project plan focused on understanding the new standard, researching issues, identifying data needs for modeling inputs, technology requirements, modeling considerations, and ensuring overarching governance was achieved for each objective and milestone. The key data driver for each model was identified, populated, and internally validated. The Company also completed data and model validation testing. The Company has performed model sensitivity analysis, developed a framework for qualitative adjustments, created supporting analytics, and executed the enhanced governance and approval process. Internal controls related to the CECL process were finalized prior to adoption.

ASU 2016-13 was adopted effective January 1, 2020 using a modified retrospective approach with no adjustments to prior period comparative financial statements. Upon adoption, the Company recorded a cumulative effective adjustment to decrease retained earnings by $25,018, with corresponding adjustments to the allowance for credit losses on loans and unfunded commitments in addition to recording a deferred tax asset on its consolidated balance sheet. As of that date, the

In December 2018, the OCC, the Board of Governors of the Federal Reserve System, and the FDIC approved a final rule to address changes to credit loss accounting under GAAP, including banking organizations’ implementation of CECL. The final rule provides banking organizations the option to phase in over a three-year period the day-one adverse effects on regulatory capital that may result from the adoption of the new accounting standard. In March 2020, the OCC, the Board of Governors of the Federal Reserve System, and the FDIC announced an interim final rule to delay the estimated impact on regulatory capital stemming from the implementation of CECL. The interim final rule maintains the three-year transition option in the previous rule and provides banks the option to delay for two years an estimate of CECL’s effect on regulatory capital, relative to the incurred loss methodology’s effect on regulatory capital, followed by a three-year transition period (five-year transition option). The Company elected the five-year capital transition relief option.

In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates step two from the goodwill impairment test. Instead, an entity may perform only step one of its quantitative goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and then recognize an impairment charge 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. Entities have the option to perform a qualitative assessment for a reporting unit to determine if the quantitative step one impairment test is necessary. ASU 2017-04 became effective for the Company on January 1, 2020. The adoption of this standard did not have any impact on the Company's consolidated financial statements or disclosures.

In August 2018, the FASB issued "Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurements." This update is part of the disclosure framework project and eliminates certain disclosure requirements for fair value measurements, requires entities to disclose new information, and modifies existing disclosure requirements. The update became effective on January 1, 2020 and did not have an impact on the Company's consolidated financial statements or disclosures.

In March 2019, FASB issued ASU 2019-01, "Leases (Topic 842): Codification Improvements", which aligns the guidance for fair value of the underlying assets by lessors that are not manufacturers or dealers in Topic 842 with that of existing guidance. As a result, the fair value of the underlying asset at lease commencement is its cost, reflecting any volume or trade discounts that may apply. However, if there has been a significant lapse of time between when the underlying asset is acquired and when the lease commences, the definition of fair value in Topic 820, Fair Value Measurement should be applied. ASU No. 2019-01 also requires lessors within the scope of Topic 942, "Financial Services—Depository and Lending", to present all “principal payments received under leases” within investing activities. The adoption of this standard on January 1, 2020 did not have a material impact on the Company's consolidated financial statements or disclosures.

address accrued interest, transfers between classifications or categories for loans and debt securities, recoveries, vintage disclosures, and contractual extensions and renewal options and became effective for annual periods and interim periods within those annual periods beginning after December 15, 2019. The improvements and clarifications related to Topic 815 address partial-term fair value hedges of interest-rate risk, amortization, and disclosure of fair value hedge basis adjustments and consideration of hedged contractually specified interest rates under the hypothetical method and became effective for the annual reporting period beginning January 1, 2020. The amendments related to Topic 825 contain various improvements to ASU 2016-01, including scope; held-to-maturity debt securities fair value disclosures; and remeasurement of equity securities at historical exchange rates and became effective as of January 1, 2020. The amendments in this update did not have a material impact on the financial statements.

In June 2018, FASB issued ASU 2018-07, "Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting", which expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. Consistent with the accounting for employee share-based payment awards, nonemployee share-based payment awards will be measured at grant-date fair value of the equity instruments obligated to be issued when the good has been delivered or the service rendered and any other conditions necessary to earn the right to benefit from the instruments have been satisfied. This ASU is effective for all entities for fiscal years beginnings after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted. The Company does not expect adoption of this standard to have a significant impact on the consolidated financial statements or disclosures.
