ASU 2020-04 also provides for a one-time sale and/or transfer to AFS or trading to be made for HTM debt securities that both reference an eligible reference rate and were classified as HTM before January 1, 2020. ASU 2020-04 was effective for all entities as of March 12, 2020 and through December 31, 2022. Companies can apply the ASU as of the beginning of the interim period that includes March 12, 2020 or any date thereafter. The guidance requires companies to apply the guidance prospectively to contract modifications and hedging relationships while the one-time election to sell and/or transfer debt securities classified as HTM may be made any time after March 12, 2020. We have established an officer level committee to guide our transition from LIBOR and have begun efforts to transition to alternative rates consistent with industry timelines. We have identified products that utilize LIBOR and are implementing enhanced fallback language to facilitate the transition to alternative reference rates. We are evaluating existing systems and have begun offering new rates on a limited basis. ASU 2020-04 is not expected to have a material impact on our consolidated financial statements.

With the adoption of ASU 2016-13, for those AFS debt securities in an unrealized loss position where management (i) has the intent to sell or (ii) where it will more-likely-than-not be required to sell the security before the recovery of its amortized cost basis, we write the security down to fair value with an adjustment to earnings. For those AFS debt securities in an unrealized loss position that do not meet either of these criteria, management assesses whether the decline in fair value has resulted from credit-related factors, using both qualitative and quantitative criteria. Determining the allowance under the credit loss method requires the use of a discounted cash flow method to assess the credit losses. Any credit-related impairment will be recognized in allowance for credit losses on the balance sheet with a corresponding adjustment to earnings. Noncredit-related impairment, the portion of the impairment relating to factors other than credit (such as changes in market interest rates), is recognized in other comprehensive income, net of tax.
Based on our consideration of the qualitative factors associated with each security type in our AFS portfolio, we did not recognize any unrealized losses in income on our AFS securities during the three and six months ended June 30, 2021 or 2020. Our state and political subdivisions are highly rated municipal securities with a long history of no credit losses. Our AFS MBS are highly rated securities which are either explicitly or implicitly backed by the U.S. Government through its agencies which are highly rated by major ratings agencies and also have a long history of no credit losses. Our corporate bonds and other investment securities as of June 30, 2021 consist of highly rated investment grade bonds. Management does not intend to sell and it is likely we will not be required to sell those securities in an unrealized loss position prior to the anticipated recovery of the amortized cost basis. These unrealized losses on our investment and MBS are largely due to changes in interest rates and spreads and other market conditions impacted by COVID-19. As of June 30, 2021 and December 31, 2020, we did not have an allowance for credit losses on our AFS securities.
We assess the likelihood of default and the potential amount of default when assessing our HTM securities for credit losses. We utilize term structures and, due to no prior loss exposure on our state and political subdivision securities, we currently apply a third-party average loss given default rate to model our securities. Due to a small number of HTM municipal securities in our portfolio as of June 30, 2021 and 2020, we elected to use the specific identification method to model these securities which aligns with our third-party fair value measurement process. The model determined any expected credit loss over the life of these securities to be remote. Management further evaluated the remote expectation of loss along with the qualitative factors

associated with these securities and concluded that, due to the securities being highly rated municipals with a long history of no credit losses, no credit loss should be recognized for these securities for the three and six months ended June 30, 2021 or 2020.
From time to time, we have transferred securities from AFS to HTM due to overall balance sheet strategies. The remaining net unamortized, unrealized loss on the transferred securities included in AOCI in the accompanying balance sheets totaled $2.1 million ($1.6 million, net of tax) at June 30, 2021 and $2.9 million ($2.3 million, net of tax) at December 31, 2020. Any net unrealized gain or loss on the transferred securities included in AOCI at the time of transfer will be amortized over the remaining life of the underlying security as an adjustment to the yield on those securities. Securities transferred with losses included in AOCI continue to be included in management’s assessment for impairment for each individual security. There were no securities transferred from AFS to HTM during the six months ended June 30, 2021 or the year ended December 31, 2020.
The accrued interest receivable on our debt securities is excluded from the credit loss estimate and is included in interest receivable on our consolidated balance sheets. As of June 30, 2021, accrued interest receivable on AFS and HTM debt securities totaled $22.9 million and $251,000, respectively. As of December 31, 2020, accrued interest receivable on AFS and HTM debt securities totaled $22.0 million and $298,000, respectively. No HTM debt securities were past-due or on nonaccrual status as of June 30, 2021 or December 31, 2020.

There was a $2.0 million net realized gain from the AFS securities portfolio for the six months ended June 30, 2021, which consisted of $2.1 million in realized gains and $52,000 in realized losses.  There was a $8.2 million net realized gain from the AFS securities portfolio for the six months ended June 30, 2020, which consisted of $8.3 million in realized gains and $89,000 in realized losses. There were no sales from the HTM portfolio during the six months ended June 30, 2021 or 2020.  We calculate realized gains and losses on sales of securities under the specific identification method.
Expected maturities on our securities may differ from contractual maturities because issuers may have the right to call or prepay obligations.  MBS are presented in total by category since MBS are typically issued with stated principal amounts and are backed by pools of mortgages that have loans with varying maturities.  The characteristics of the underlying pool of mortgages, such as fixed-rate or adjustable-rate, as well as prepayment risk, are passed on to the security holder.  The term of a mortgage-backed pass-through security thus approximates the term of the underlying mortgages and can vary significantly due to prepayments.

Equity investments on our consolidated balance sheets include Community Reinvestment Act funds with a readily determinable fair value as well as equity investments without readily determinable fair values. At June 30, 2021 and December 31, 2020, we had equity investments recorded in our consolidated balance sheets of $11.8 million and $11.9 million, respectively.
Any realized and unrealized gains and losses on equity investments are reported in income. Equity investments without readily determinable fair values are recorded at cost less impairment, if any.

Paycheck Protection Program Loans
In April 2020, we began originating loans to qualified small businesses under the PPP administered by the SBA under the provisions of the CARES Act. Loans covered by the PPP may be eligible for loan forgiveness for certain costs incurred related to payroll, group health care benefit costs and qualifying mortgage, rent and utility payments. The remaining loan balance after forgiveness of any amount is still fully guaranteed by the SBA. On December 27, 2020, the Economic Aid Act was signed into law. This second coronavirus relief package granted additional funds for a new round of PPP loans. Additionally, it expanded the eligibility for loans and allowed certain businesses to request a second loan. In return for processing and booking a PPP loan, the SBA paid lenders a processing fee tiered by the size of the loan. These loans are included in commercial loans with an amortized cost basis at June 30, 2021 and December 31, 2020 of $132.1 million and $214.8 million, respectively.
Construction Real Estate Loans
Our construction loans are collateralized by property located primarily in or near the market areas we serve. A number of our construction loans will be owner occupied upon completion. Construction loans for non-owner occupied projects are financed, but these typically have cash flows from leases with tenants, secondary sources of repayment, and in some cases, additional collateral. Our construction loans have both adjustable and fixed interest rates during the construction period. Construction loans to individuals are typically priced and made with the intention of granting the permanent loan on the completed property. Speculative and commercial construction loans are subject to underwriting standards similar to that of the commercial portfolio.  Owner occupied 1-4 family residential construction loans are subject to the underwriting standards of the permanent loan.
1-4 Family Residential Real Estate Loans
Residential loan originations are generated by our loan officers, in-house origination staff, marketing efforts, present customers, walk-in customers and referrals from real estate agents and builders.  We focus our lending efforts primarily on the origination of loans secured by first mortgages on owner occupied 1-4 family residences.  Substantially all of our 1-4 family residential originations are secured by properties located in or near our market areas.  
Our 1-4 family residential loans generally have maturities ranging from five to 30 years.  These loans are typically fully amortizing with monthly payments sufficient to repay the total amount of the loan.  Our 1-4 family residential loans are made at both fixed and adjustable interest rates.
Underwriting for 1-4 family residential loans includes debt-to-income analysis, credit history analysis, appraised value and down payment considerations. Changes in the market value of real estate can affect the potential losses in the portfolio.
Commercial Real Estate Loans
Commercial real estate loans as of June 30, 2021 consisted of $1.24 billion of owner and non-owner occupied real estate, $170.4 million of loans secured by multi-family properties and $18.5 million of loans secured by farmland. Commercial real estate loans primarily include loans collateralized by retail, commercial office buildings, multi-family residential buildings, medical facilities and offices, senior living, assisted living and skilled nursing facilities, warehouse facilities, hotels and churches. In determining whether to originate commercial real estate loans, we generally consider such factors as the financial condition of the borrower and the debt service coverage of the property. Commercial real estate loans are made at both fixed and adjustable interest rates for terms generally up to 20 years.

Table of Contents

Commercial Loans
Our commercial loans are diversified loan types including short-term working capital loans for inventory and accounts receivable and short- and medium-term loans for equipment or other business capital expansion.  In our commercial loan underwriting, we assess the creditworthiness, ability to repay and the value and liquidity of the collateral being offered.  Terms of commercial loans are generally commensurate with the useful life of the collateral offered.
Municipal Loans
We make loans to municipalities and school districts primarily throughout the state of Texas, with a small percentage originating outside of the state.  The majority of the loans to municipalities and school districts have tax or revenue pledges and in some cases are additionally supported by collateral.  Municipal loans made without a direct pledge of taxes or revenues are usually made based on some type of collateral that represents an essential service. Lending money directly to these municipalities allows us to earn a higher yield than we could if we purchased municipal securities for similar durations.
Loans to Individuals
Substantially all originations of our loans to individuals are made to consumers in our market areas.  The majority of loans to individuals are collateralized by titled equipment, which are primarily automobiles. Loan terms vary according to the type and value of collateral, length of contract and creditworthiness of the borrower.  The underwriting standards we employ for consumer loans include an application, a determination of the applicant’s payment history on other debts, with the greatest weight being given to payment history with us and an assessment of the borrower’s ability to meet existing obligations and payments on the proposed loan.  Although creditworthiness of the applicant is a primary consideration, the underwriting process also includes a comparison of the value of the collateral, if any, in relation to the proposed loan amount. Most of our loans to individuals are collateralized, which management believes assists in limiting our exposure.
Credit Quality Indicators
We categorize loans into risk categories on an ongoing basis based on relevant information about the ability of borrowers to service their debt such as:  current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors.  We use the following definitions for risk ratings:
Pass (Rating 1 – 4) – This rating is assigned to all satisfactory loans.  This category, by definition, consists of acceptable credit.  Credit and collateral exceptions should not be present, although their presence would not necessarily prohibit a loan from being rated Pass, if deficiencies are in the process of correction.  These loans are not included in the Watch List.
Pass Watch (Rating 5) – These loans require some degree of special treatment, but not due to credit quality.  This category does not include loans specially mentioned or adversely classified; however, particular attention is warranted to characteristics such as:
A lack of, or abnormally extended payment program;
A heavy degree of concentration of collateral without sufficient margin;
A vulnerability to competition through lesser or extensive financial leverage; and
A dependence on a single or few customers or sources of supply and materials without suitable substitutes or alternatives.
Special Mention (Rating 6) – A Special Mention loan has potential weaknesses that deserve management’s close attention.  If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in our credit position at some future date.  Special Mention loans are not adversely classified and do not expose us to sufficient risk to warrant adverse classification.
Substandard (Rating 7) – Substandard loans are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any.  Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt.  They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected.
Doubtful (Rating 8) – Loans classified as Doubtful have all the weaknesses inherent in those classified Substandard with the added characteristic that the weaknesses make collection or liquidation, in full, on the basis of currently known facts, conditions and values, highly questionable and improbable.

(1)    Includes $810,000 and $976,000 of restructured loans as of June 30, 2021 and December 31, 2020, respectively.

We reversed $12,000 and $25,000 of interest income on nonaccrual loans during the three and six months ended June 30, 2021, respectively, and $14,000 and $143,000 for the three and six months ended June 30, 2020, respectively. We had $1.4 million and $2.2 million of loans on nonaccrual for which there was no related allowance for credit losses as of June 30, 2021 and December 31, 2020, respectively.
Collateral-dependent loans are loans that we expect the repayment to be provided substantially through the operation or sale of the collateral of the loan and we have determined that the borrower is experiencing financial difficulty. In such cases, expected credit losses are based on the fair value of the collateral at the measurement date, adjusted for selling costs. As of June 30, 2021 and December 31, 2020, we had $10.1 million and $11.5 million, respectively, of collateral-dependent loans, secured mainly by real estate and equipment. There have been no significant changes to the collateral that secures the collateral-dependent assets. Foreclosed assets include OREO and repossessed assets. For 1-4 family residential real estate properties, a loan is recognized as a foreclosed property once legal title to the real estate property has been received upon completion of foreclosure or the borrower has conveyed all interest in the residential property through a deed in lieu of foreclosure. There were $34,000 and $1.2 million in loans secured by 1-4 family residential properties for which formal foreclosure proceedings were in process as of June 30, 2021 and December 31, 2020, respectively.

Troubled Debt Restructurings
The restructuring of a loan is considered a TDR if both (i) the borrower is experiencing financial difficulties and (ii) the creditor has granted a concession.  Concessions may include interest rate reductions or below market interest rates, restructuring amortization schedules and other actions intended to minimize potential losses. We may provide a combination of concessions which may include an extension of the amortization period, interest rate reduction and/or converting the loan to interest-only for a limited period of time.
In response to the impact of the COVID-19 pandemic on the economy, the CARES Act was signed into law. Under the CARES Act, banks may elect to deem that loan modifications do not result in TDRs if they are: (1) related to COVID-19; (2) executed on a loan that was not more than 30 days past due as of December 31, 2019; and (3) executed between March 1, 2020, and the earlier of (A) 60 days after the date of termination of the national emergency declaration or (B) December 31, 2020. The Economic Aid Act extended this relief to the earlier of 60 days after the national emergency termination date or January 1, 2022. Additionally, in accordance with the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (Revised), other short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not TDRs under ASC Subtopic 310-40. This includes short-term (e.g., up to six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or delays in payment that are insignificant. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. Loans modified under this guidance are not considered TDRs and as such are not identified in the table below. At June 30, 2021 and December 31, 2020, we had outstanding loans with payment deferrals totaling $182,000 and $47.2 million, respectively.

Interest continues to be charged on principal balances outstanding during the extended term. Therefore, the financial effects of the recorded investment of loans restructured as TDRs during the six months ended June 30, 2021 and 2020 were not significant. Generally, the loans identified as TDRs were previously reported as impaired loans prior to restructuring, and therefore, the modification did not impact our determination of the allowance for loans losses.
On an ongoing basis, the performance of the TDRs is monitored for subsequent payment default. Payment default for TDRs is recognized when the borrower is 90 days or more past due. For the three and six months ended June 30, 2021, TDRs in default totaled $230,000. For the three and six months ended June 30, 2020 the amount of TDRs in default was not significant. Payment defaults for TDRs did not significantly impact the determination of the allowance for loan losses in the periods presented.
At June 30, 2021 and 2020, there were no commitments to lend additional funds to borrowers whose terms had been modified in TDRs.
Allowance for Loan Losses
In accordance with ASC 326, the allowance for credit losses on loans is estimated and recognized upon origination of the loan based on expected credit losses. The CECL model uses historical experience and current conditions for homogeneous pools of loans, and reasonable and supportable forecasts about future events. The impact of varying economic conditions and portfolio stress factors are a component of the credit loss models applied to each portfolio. Reserve factors are specific to the loan segments that share similar risk characteristics based on the probability of default assumptions and loss given default assumptions, over the contractual term. The forecasted periods gradually mean-revert the economic inputs to their long-run historical trends. Management evaluates the economic data points used in the Moody’s forecasting scenarios on a quarterly basis to determine the most appropriate impact to the various portfolio characteristics based on management’s view and applies weighting to various forecasting scenarios as deemed appropriate based on known and expected economic activities. Management also considers and may apply relevant qualitative factors, not previously considered, to determine the appropriate allowance level. The use of the CECL model includes significant judgment by management and may differ from those of our peers due to different historical loss patterns, economic forecasts, and the length of time of the reasonable and supportable forecast period and reversion period.
We utilize Moody’s Analytics economic forecast scenarios and assign probability weighting to those scenarios which best reflect management’s views on the economic forecast. The probability weighting and scenarios utilized for the estimate of the allowance were generally reflective of an improved economic forecast based on known and knowable information as of June 30, 2021.
When determining the appropriate allowance for credit losses on our loan portfolio, our commercial construction and real estate loans, commercial loans and municipal loans utilize the probability of default/loss given default discounted cash flow approach. Reserves on these loans are based upon risk factors including the loan type and structure, collateral type, leverage ratio, refinancing risk and origination quality, among others. Our consumer construction real estate loans, 1-4 family residential loans and our loans to individuals use a loss rate based upon risk factors including loan types, origination year and credit scores. Loans covered by the PPP may be eligible for loan forgiveness. The remaining loan balance after forgiveness of any amount is still fully guaranteed by the SBA and therefore does not have an associated allowance.
Loans evaluated collectively in a pool are monitored to ensure they continue to exhibit similar risk characteristics with other loans in the pool. If a loan does not share similar risk characteristics with other loans, expected credit losses for that loan are evaluated individually.

(1)    The increase in the provision for credit losses during 2020 was primarily due to the economic impact of COVID-19 on macroeconomic factors used in the CECL model.

The accrued interest receivable on our loan receivables is excluded from the allowance for credit loss estimate and is included in interest receivable on our consolidated balance sheets. As of June 30, 2021 and December 31, 2020, the accrued interest on our loan portfolio was $13.4 million and $16.4 million, respectively.

Other borrowings include federal funds purchased, repurchase agreements and borrowings from the FRDW. Southside Bank has three unsecured lines of credit for the purchase of overnight federal funds at prevailing rates with Frost Bank, TIB – The Independent Bankers Bank and Comerica Bank for $40.0 million, $15.0 million and $7.5 million, respectively. There were no federal funds purchased at June 30, 2021 or December 31, 2020.  To provide more liquidity in response to the economic impact of the COVID-19 pandemic, the Federal Reserve took steps to encourage broader use of the discount window. At June 30, 2021, the amount of additional funding the Bank could obtain from the FRDW, collateralized by securities, was approximately $487.7 million. There were no borrowings from the FRDW at June 30, 2021 or December 31, 2020. Southside Bank has a $5.0 million line of credit with Frost Bank to be used to issue letters of credit, and at June 30, 2021, the line had one outstanding letter of credit for $91,000. Southside Bank currently has no outstanding letters of credit from FHLB held as collateral for its public fund deposits.
Southside Bank enters into sales of securities under repurchase agreements. These repurchase agreements totaled $23.8 million at June 30, 2021 and $23.2 million at December 31, 2020, and had maturities of less than one year.  Repurchase agreements are secured by investment and MBS securities and are stated at the amount of cash received in connection with the transaction.
FHLB borrowings represent borrowings with fixed interest rates ranging from 0.08% to 4.799% and with remaining maturities of one day to 7.0 years at June 30, 2021.  FHLB borrowings may be collateralized by FHLB stock, nonspecified loans and/or securities. At June 30, 2021, the amount of additional funding Southside Bank could obtain from FHLB, collateralized by

securities, FHLB stock and nonspecified loans and securities, was approximately $1.23 billion, net of FHLB stock purchases required.  
Southside Bank has entered into various variable rate agreements and fixed rate short-term pay agreements with third-party financial institutions with rates tied to LIBOR. These agreements totaled $605.0 million at June 30, 2021 and $670.0 million at December 31, 2020. Six of the agreements have an interest rate tied to three-month LIBOR, and the remaining agreements have interest rates tied to one-month LIBOR. In connection with all of these agreements, Southside Bank also entered into various interest rate swap contracts that are treated as cash flow hedges under ASC Topic 815, “Derivatives and Hedging” that are expected to be effective in hedging the variability in future cash flows attributable to fluctuations in the underlying LIBOR interest rate. The interest rate swap contracts had a weighted average rate of 1.14% with a weighted average maturity of 3.7 years at June 30, 2021. Refer to “Note 9 – Derivative Financial Instruments and Hedging Activities” in our consolidated financial statements included in this report for a detailed description of our hedging policy and methodology related to derivative instruments.

9.    Derivative Financial Instruments and Hedging Activities
Our hedging policy allows the use of interest rate derivative instruments to manage our exposure to interest rate risk or hedge specified assets and liabilities. These instruments may include interest rate swaps and interest rate caps and floors. All derivative instruments are carried on the balance sheet at their estimated fair value and are recorded in other assets or other liabilities, as appropriate.
Derivative instruments may be designated as cash flow hedges of variable rate assets or liabilities, cash flow hedges of forecasted transactions, fair value hedges of a recognized asset or liability or as non-hedging instruments. Gains and losses on derivative instruments designated as cash flow hedges are recorded in AOCI to the extent they are effective. If the hedge is effective, the amount recorded in other comprehensive income is reclassified to earnings in the same periods that the hedged cash flows impact earnings. The ineffective portion of changes in fair value is reported in current earnings. Gains and losses on derivative instruments designated as fair value hedges, as well as the change in fair value on the hedged item, are recorded in interest income in the consolidated statements of income. Gains and losses due to changes in fair value of the interest rate swap agreements completely offset changes in the fair value of the hedged portion of the hedged item. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in current earnings during the period of change.
We have entered into certain interest rate swap contracts on specific variable rate agreements and fixed rate short-term pay agreements with third-party financial institutions. These interest rate swap contracts were designated as hedging instruments in cash flow hedges under ASC Topic 815. The objective of the interest rate swap contracts is to manage the expected future cash flows on $605.0 million of debt. The cash flows from the swap contracts are expected to be effective in hedging the variability in future cash flows attributable to fluctuations in the underlying LIBOR interest rate.
In accordance with ASC Topic 815, if a hedging item is terminated prior to maturity for a cash settlement, the existing gain or loss within AOCI will continue to be reclassified into earnings during the period or periods in which the hedged forecasted transaction affects earnings unless it is probable the forecasted transaction will not occur by the end of the originally specified time period. These transactions are reevaluated on a monthly basis to determine if the hedged forecasted transactions are still probable of occurring. If at a subsequent evaluation, it is determined that the transactions will not occur, any related gains or losses recorded in AOCI are immediately recognized in earnings.
From time to time, we may enter into certain interest rate swaps, cap and floor contracts that are not designated as hedging instruments. These interest rate derivative contracts relate to transactions in which we enter into an interest rate swap, cap or floor with a customer while concurrently entering into an offsetting interest rate swap, cap or floor with a third party financial institution. We agree to pay interest to the customer on a notional amount at a variable rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, we agree to pay a third party financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. These interest rate derivative contracts allow our customers to effectively convert a variable rate loan to a fixed rate loan. The changes in the fair value of the underlying derivative contracts primarily offset each other and do not significantly impact our results of operations. We recognized swap fee income associated with these derivative contracts immediately based upon the difference in the bid/ask spread of the underlying transactions with the customer and the third party financial institution. The swap fee income is included in other noninterest income in our consolidated statements of income.
At June 30, 2021 and December 31, 2020, net derivative liabilities included $25.9 million and $39.3 million, respectively, of cash collateral held by counterparties subject to master netting agreements.
The notional amounts of the derivative instruments represent the contractual cash flows pertaining to the underlying agreements. These amounts are not exchanged and are not reflected in the consolidated balance sheets. The fair value of the interest rate swaps are presented at net in other assets and other liabilities when a right of offset exists, based on transactions with a single counterparty that are subject to a legally enforceable master netting agreement.

(2)    Net derivative assets are included in other assets and net derivative liabilities are included in other liabilities on the consolidated balance sheets. Included in the fair value of net derivative assets and net derivative liabilities are credit valuation adjustments reflecting counterparty credit risk and our credit risk. We had no credit exposure related to interest rate swaps with financial institutions and $16.6 million related to interest rate swaps with customers at June 30, 2021. We had no credit exposure related to interest rate swaps with financial institutions and $18.5 million related to interest rate swaps with customers at December 31, 2020. The credit risk associated with customer transactions is partially mitigated as these are generally secured by the non-cash collateral securing the underlying transaction being hedged.

10.  Fair Value Measurement
Fair value is the price that would be received upon the sale of an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants.  A fair value measurement assumes 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.  The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs.  An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction.  Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact.
Valuation techniques including the market approach, the income approach and/or the cost approach are utilized to determine fair value.  Inputs to valuation techniques refer to the assumptions market participants would use in pricing the asset or liability.  Valuation policies and procedures are determined by our investment department and reported to our ALCO for review.  An entity must consider all aspects of nonperforming risk, including the entity’s own credit standing, when measuring fair value of a liability.  Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.  A fair value hierarchy for valuation inputs 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 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, credit risks, etc.) 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.
Certain financial assets are measured at fair value in accordance with GAAP.  Adjustments to the fair value of these assets usually result from the application of fair value accounting or write-downs of individual assets. A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.
Securities AFS and Equity Investments with readily determinable fair values – U.S. Treasury securities and equity investments with readily determinable fair values are reported at fair value utilizing Level 1 inputs.  Other securities classified as AFS are reported at fair value utilizing Level 2 inputs.  For these securities, we obtain fair value measurements from independent pricing services and obtain an understanding of the pricing methodologies used by these independent pricing services. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things, as stated in the pricing methodologies of the independent pricing services.
We review and validate the prices supplied by the independent pricing services for reasonableness by comparison to prices obtained from, in some cases, two additional third-party sources. For securities where prices are outside a reasonable range, we further review those securities, based on internal ALCO approved procedures, to determine what a reasonable fair value measurement is for those securities, given available data.
Derivatives – Derivatives are reported at fair value utilizing Level 2 inputs. We obtain fair value measurements from two sources including an independent pricing service and the counterparty to the derivatives designated as hedges.  The fair value measurements consider observable data that may include dealer quotes, market spreads, the U.S. Treasury yield curve, live trading levels, trade execution data, credit information and the derivatives’ terms and conditions, among other things. We review the prices supplied by the sources for reasonableness.  In addition, we obtain a basic understanding of their underlying pricing methodology.  We validate prices supplied by the sources by comparison to one another.
Certain nonfinancial assets and nonfinancial liabilities measured at fair value on a recurring basis include reporting units measured at fair value and tested for goodwill impairment. 
Southside Bancshares, Inc. |35

Table of Contents

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis, which means that the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets and financial liabilities measured at fair value on a nonrecurring basis included foreclosed assets and collateral-dependent loans at June 30, 2021 and December 31, 2020.
Foreclosed Assets – Foreclosed assets are initially recorded at fair value less costs to sell.  The fair value measurements of foreclosed assets can include Level 2 measurement inputs such as real estate appraisals and comparable real estate sales information, in conjunction with Level 3 measurement inputs such as cash flow projections, qualitative adjustments and sales cost estimates.  As a result, the categorization of foreclosed assets is Level 3 of the fair value hierarchy.  In connection with the measurement and initial recognition of certain foreclosed assets, we may recognize charge-offs through the allowance for credit losses.
Collateral-Dependent Loans (Impaired loans prior to the adoption of ASU 2016-13) – Certain loans may be reported at the fair value of the underlying collateral if repayment is expected substantially from the operation or sale of the collateral.  Collateral values are estimated using Level 3 inputs based on customized discounting criteria or appraisals.  At June 30, 2021 and December 31, 2020, the impact of the fair value of collateral-dependent loans was reflected in our allowance for loan losses.
The fair value estimate of financial instruments for which quoted market prices are unavailable is dependent upon the assumptions used.  Consequently, those estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments.  Accordingly, the aggregate fair value amounts presented in the fair value tables do not necessarily represent their underlying value.

Disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, is required when it is practicable to estimate that value.  In cases where quoted market prices are not available, fair values are based on estimates using present value or other estimation techniques.  Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.  Such techniques and assumptions, as they apply to individual categories of our financial instruments, are as follows:
Cash and cash equivalents – The carrying amount for cash and cash equivalents is a reasonable estimate of those assets’ fair value.
Investment and MBS HTM – Fair values for these securities are based on quoted market prices, where available.  If quoted market prices are not available, fair values are based on quoted market prices for similar securities or estimates from independent pricing services.
FHLB stock – The carrying amount of FHLB stock is a reasonable estimate of the fair value of those assets.
Equity investments – The carrying value of equity investments without readily determinable fair values are measured at cost less impairment, if any, adjusted for observable price changes for an identical or similar investment of the same issuer. This carrying value is a reasonable estimate of the fair value of those assets.
Loans receivable – We estimate the fair value of our loan portfolio to an exit price notion with adjustments for liquidity, credit and prepayment factors. Nonperforming loans continue to be estimated using discounted cash flow analyses or the underlying value of the collateral where applicable.
Loans held for sale – The fair value of loans held for sale is determined based on expected proceeds, which are based on sales contracts and commitments.
Deposit liabilities – The fair value of demand deposits, savings accounts and certain money market deposits is the amount on demand at the reporting date, which is the carrying value.  Fair values for fixed rate CDs are estimated using a discounted cash flow calculation that applies interest rates currently being offered for deposits of similar remaining maturities.
Other borrowings – Federal funds purchased generally have original terms to maturity of one day and repurchase agreements generally have terms of less than one year, and therefore both are considered short-term borrowings. Consequently, their carrying value is a reasonable estimate of fair value.
FHLB borrowings – The fair value of these borrowings is estimated by discounting the future cash flows using rates at which borrowings would be made to borrowers with similar credit ratings and for the same remaining maturities.
Subordinated notes – The fair value of the subordinated notes is estimated by discounting future cash flows using estimated rates at which long-term debt would be made to borrowers with similar credit ratings and for the remaining maturities.
Trust preferred subordinated debentures – The fair value of the long-term debt is estimated by discounting future cash flows using estimated rates at which long-term debt would be made to borrowers with similar credit ratings and for the remaining maturities.

11.     Income Taxes

The income tax expense included in the accompanying consolidated statements of income consists of the following (in thousands):
 Three Months Ended
June 30,
Six Months Ended
June 30,
 2021202020212020
Current income tax expense$3,026 $2,689 $5,615 $8,243 
Deferred income tax (benefit) expense(139)120 2,022 (4,955)
Income tax expense$2,887 $2,809 $7,637 $3,288 

The net deferred tax liability totaled $16.5 million at June 30, 2021 and $15.5 million at December 31, 2020.  No valuation allowance was recorded at June 30, 2021 or December 31, 2020, as management believes it is more likely than not that all of the deferred tax asset items will be realized in future years. Unrecognized tax benefits were not material at June 30, 2021 or December 31, 2020.
We recognized income tax expense of $2.9 million and $7.6 million, for an ETR of 11.9% and 12.1% for the three and six months ended June 30, 2021, respectively, compared to income tax expense of $2.8 million and $3.3 million, for an ETR of 11.5% and 11.4%, for the three and six months ended June 30, 2020, respectively. The higher ETR for the six months ended June 30, 2021 was primarily due to a decrease in tax-exempt income as a percentage of pre-tax income as compared to the same period in 2020. The ETR differs from the statutory rate of 21% for the three and six months ended June 30, 2021 and 2020 primarily due to the effect of tax-exempt income from municipal loans and securities, as well as BOLI. We file income tax returns in the U.S. federal jurisdictions and in certain states. We are no longer subject to U.S. federal income tax examinations by tax authorities for years before 2017 or Texas state tax examinations by tax authorities for years before 2016.

12.     Off-Balance-Sheet Arrangements, Commitments and Contingencies

Financial Instruments with Off-Balance-Sheet Risk. In the normal course of business, we are a party to certain financial instruments with off-balance-sheet risk to meet the financing needs of our customers. These off-balance-sheet instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount reflected in the financial statements. The contract or notional amounts of these instruments reflect the extent of involvement and exposure to credit loss that we have in these particular classes of financial instruments. The allowance for credit losses on these off-balance-sheet credit exposures is calculated using the same methodology as loans including a conversion or usage factor to anticipate ultimate exposure and expected losses and is included in other liabilities on our consolidated balance sheets.
Allowance for off-balance-sheet credit exposures were as follows (in thousands):

Balance at end of period$3,773 $6,365 $3,773 $6,365 

Contractual commitments to extend credit are agreements to lend to a customer provided the terms established in the contract are met.  Commitments to extend credit generally have fixed expiration dates and may require the payment of fees.  Since some commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. These guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in commitments to extend credit and similarly do not necessarily represent future cash obligations.
Financial instruments with off-balance-sheet risk were as follows (in thousands):
 June 30, 2021December 31, 2020
  
Commitments to extend credit$922,234 $793,138 
Standby letters of credit10,785 13,658 
Total$933,019 $806,796 

We apply the same credit policies in making commitments to extend credit and standby letters of credit as we do for on-balance-sheet instruments.  We evaluate each customer’s creditworthiness on a case-by-case basis.  The amount of collateral obtained, if deemed necessary, upon extension of credit is based on management’s credit evaluation of the borrower.  Collateral held varies but may include cash or cash equivalents, negotiable instruments, real estate, accounts receivable, inventory, oil, gas and mineral interests, property, plant and equipment.
Leases. During the three months ended June 30, 2021, there were no operating lease ROU assets obtained in exchange for new operating lease liabilities. During the six months ended June 30, 2021, there were $1.1 million of operating lease ROU assets obtained in exchange for new operating lease liabilities, primarily due to one lease that commenced in January 2021 with an initial ROU asset of $1.1 million. During the three and six months ended June 30, 2020, there were $7.8 million and $8.0 million, respectively, of operating lease ROU assets obtained in exchange for new operating lease liabilities, primarily due to one lease that commenced in May 2020 with an initial ROU asset of $6.6 million.
Securities. In the normal course of business we buy and sell securities. At June 30, 2021, there were $41.9 million of unsettled trades to purchase securities and no unsettled trades to sell securities. At December 31, 2020, there were no unsettled trades to purchase securities and no unsettled trades to sell securities.
Deposits. There were no unsettled issuances of brokered CDs at June 30, 2021 or December 31, 2020.

ITEM 2.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following is a discussion of our consolidated financial condition, changes in our financial condition and results of our operations, and should be read and reviewed in conjunction with the financial statements, and the notes thereto, in this Quarterly Report on Form 10-Q and in our 2020 Form 10-K. Certain risks, uncertainties and other factors, including those set forth under "Risk Factors" in Part I, Item 1A. of the 2020 Form 10-K and elsewhere in this Quarterly Report on Form 10-Q, may cause actual results to differ materially from the results discussed in the forward-looking statements appearing in this discussion and analysis.
Forward-Looking Statements
Certain statements of other than historical fact that are contained in this report may be considered to be “forward-looking statements” within the meaning of and subject to the safe harbor protections of the Private Securities Litigation Reform Act of 1995.  These forward-looking statements are not guarantees of future performance, nor should they be relied upon as representing management’s views as of any subsequent date.  These statements may include words such as “expect,” “estimate,” “project,” “anticipate,” “appear,” “believe,” “could,” “should,” “may,” “might,” “will,” “would,” “seek,” “intend,” “probability,” “risk,” “goal,” “target,” “objective,” “plans,” “potential,” and similar expressions. Forward-looking statements are statements with respect to our beliefs, plans, expectations, objectives, goals, anticipations, assumptions, estimates, intentions and future performance and are subject to significant known and unknown risks and uncertainties, which could cause our actual results to differ materially from the results discussed in the forward-looking statements.  For example, discussions of the effect of our expansion, benefits of the Share Repurchase Plan, trends in asset quality, capital, liquidity, our ability to sell nonperforming assets, expense reductions, planned operational efficiencies and earnings from growth and certain market risk disclosures, including the impact of interest rates, tax reform, inflation and other economic factors are based upon information presently available to management and are dependent on choices about key model characteristics and assumptions and are subject to various limitations.  By their nature, certain of the market risk disclosures are only estimates and could be materially different from what actually occurs in the future.  Accordingly, our results could materially differ from those that have been estimated.  The most recent factor that could cause future results to differ materially from those anticipated by our forward-looking statements include the negative impact of the COVID-19 pandemic on our business, financial position, operations and prospects, including our ability to continue our business activities in certain communities we serve, the duration of the pandemic and its continued effects on financial markets, a reduction in financial transactions and business activities resulting in decreased deposits and reduced loan originations, increases in unemployment rates impacting our borrowers’ ability to repay their loans, our ability to manage liquidity in a rapidly changing and unpredictable market, additional interest rate changes by the Federal Reserve and other government actions in response to the pandemic including regulations or laws enacted to counter the effects of the COVID-19 pandemic on the economy. Other factors that could cause actual results to differ materially from those indicated by forward-looking statements include, but are not limited to, the following:
the impact of the COVID-19 pandemic on our future consolidated financial condition and results of operations;
general (i) political conditions, including, without limitation, governmental action and uncertainty resulting from U.S. and global political trends and (ii) economic conditions, either globally, nationally, in the State of Texas, or in the specific markets in which we operate, including, without limitation, the deterioration of the commercial real estate, residential real estate, construction and development, energy, oil and gas, credit or liquidity markets, which could cause an adverse change in our net interest margin, or a decline in the value of our assets, which could result in realized losses;
current or future legislation, regulatory changes or changes in monetary or fiscal policy that adversely affect the businesses in which we or our customers or our borrowers are engaged, including the impact of the Dodd-Frank Act, the Federal Reserve’s actions with respect to interest rates, the capital requirements promulgated by the Basel Committee, the CARES Act, the Economic Aid Act, uncertainty relating to calculation of LIBOR and other regulatory responses to economic conditions;
adverse changes in the status or financial condition of the GSEs which impact the GSEs’ guarantees or ability to pay or issue debt;
adverse changes in the credit portfolios of other U.S. financial institutions relative to the performance of certain of our investment securities;
economic or other disruptions caused by acts of terrorism in the United States, Europe or other areas;
technological changes, including potential cyber-security incidents and other disruptions, or innovations to the financial services industry, including as a result of the increased telework environment;

Critical Accounting Estimates
Our accounting and reporting estimates conform with U.S. GAAP and general practices within the financial services industry.  The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We consider accounting estimates that can (1) be replaced by other reasonable estimates and/or (2) changes to an estimate from period to period that have a material impact on the presentation of our financial condition, changes in financial condition or results of operations as well as (3) those estimates that require significant and complex assumptions about matters that are highly uncertain to be critical accounting estimates. We consider our critical accounting policies to include allowance for credit losses on loans, estimation of fair value and pension plan accounting.
Critical accounting estimates include a high degree of uncertainty in the underlying assumptions. Management bases its estimates on historical experience, current information and other factors deemed relevant. The development, selection and disclosure of our critical accounting estimates are reviewed with the Audit Committee of the Company's Board of Directors. Actual results could differ from these estimates. For additional information regarding critical accounting policies, refer to “Note 1 – Summary of Significant Accounting and Reporting Policies” and “Note 5 – Loans and Allowance for Loan Losses” in the notes to the consolidated financial statements and refer to “Part II - Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Estimates,” and “Note 1 – Summary of Significant Accounting and Reporting Policies” in the 2020 Form 10-K. As of June 30, 2021, there have been no significant changes to our critical accounting estimates.

Non-GAAP Financial Measures
Certain non-GAAP measures are used by management to supplement the evaluation of our performance. These include the following fully taxable-equivalent measures: Net interest income (FTE), net interest margin (FTE) and net interest spread (FTE), which include the effects of taxable-equivalent adjustments using a federal income tax rate of 21% for the three and six months ended June 30, 2021 and 2020, to increase tax-exempt interest income to a tax-equivalent basis. Interest income earned on certain assets is completely or partially exempt from federal income tax. As such, these tax-exempt instruments typically yield lower returns than taxable investments.
Net interest income (FTE), net interest margin (FTE) and net interest spread (FTE).  Net interest income (FTE) is a non-GAAP measure that adjusts for the tax-favored status of net interest income from certain loans and investments and is not permitted under GAAP in the consolidated statements of income. We believe this measure to be the preferred industry measurement of net interest income, and that it enhances comparability of net interest income arising from taxable and tax-exempt sources. The most directly comparable financial measure calculated in accordance with GAAP is our net interest income. Net interest margin (FTE) is the ratio of net interest income (FTE) to average earning assets. The most directly comparable financial measure calculated in accordance with GAAP is our net interest margin. Net interest spread (FTE) is the difference in the average yield on average earning assets on a tax-equivalent basis and the average rate paid on average interest bearing liabilities. The most directly comparable financial measure calculated in accordance with GAAP is our net interest spread.
These non-GAAP financial measures should not be considered alternatives to GAAP-basis financial statements and other bank holding companies may define or calculate these non-GAAP measures or similar measures differently. Whenever we present a non-GAAP financial measure in an SEC filing, we are also required to present the most directly comparable financial measure calculated and presented in accordance with GAAP and reconcile the differences between the non-GAAP financial measure and such comparable GAAP measure.
In the following table we present the reconciliation of net interest income to net interest income adjusted to a fully taxable-equivalent basis assuming a 21% marginal tax rate for the three and six months ended June 30, 2021 and 2020, for interest earned on tax-exempt assets such as municipal loans and investment securities (dollars in thousands), along with the calculation of net interest margin (FTE) and net interest spread (FTE).

OVERVIEW
COVID-19
During March 2020, the World Health Organization declared COVID-19 a global pandemic in response to the rapidly growing outbreak of the virus. COVID-19 significantly impacted local, national and global economies due to stay-at-home orders and social distancing guidelines. In compliance with social distancing guidelines issued by federal, state and local governments, we initially closed all of our grocery store branches. As stay-at-home orders were issued by local governments in our market areas to combat the spread of the virus, we closed all traditional lobbies and wealth management and trust offices to walk-in customers, however, most of these traditional locations were offering certain services by appointment only. All other banking services were available to customers through our drive-thrus, ATMs/ITMs and automated telephone, internet and mobile banking products. After careful consideration and implementation of additional safety precautions, all locations were reopened on June 1, 2020. We have since made adjustments to select branch hours and openings, and we continue to closely monitor the COVID-19 situation. Approximately 45% of our workforce has remote working capabilities, however most of our workforce have returned to our office and branch locations.
COVID-19 significantly disrupted supply chains, business activity and the overall economic and financial markets.  These disruptions have and are likely to continue to result in a decline in demand for banking products or services, including loans and deposits which could impact our future financial condition, results of operations and liquidity. As of June 30, 2021, most businesses in Texas are re-opened without restrictions. Commercial activity has improved but has not returned to the levels existing prior to the outbreak of the pandemic. The extent to which the COVID-19 pandemic affects our business, operations and financial condition, as well as our regulatory capital and liquidity ratios and credit ratings, is highly uncertain and unpredictable and depends on, among other things, new information that may emerge concerning the scope, duration and severity of the COVID-19 pandemic, actions taken by governmental authorities and other parties in responses to the pandemic, the scale of the distribution and public acceptance of the vaccines for COVID-19 and the effectiveness of such vaccines in stemming or stopping the spread of COVID-19 and any related variants. While the overall outlook has improved based on the availability of the vaccine, there has been a recent rise in hospitalization and infection rates caused by the Delta variant, a rapidly spreading strain of coronavirus. Therefore, the risk of further resurgence and possible reimplementation of restrictions remains. The adverse impact on the markets in which we operate and on our business, operations and financial condition is expected to remain elevated until the pandemic subsides.   
In response to the COVID-19 pandemic, the CARES Act was signed into law on March 27, 2020. The CARES Act provided an estimated $2.2 trillion to address the economic impact of the COVID-19 pandemic and stimulate the economy by supporting individuals and businesses through loans, grants, tax changes, and other types of relief. The CARES Act also included provisions to encourage financial institutions to work prudently with borrowers. As an SBA lender, we were well positioned to assist business customers in accessing funds available through the PPP implemented in April of 2020. On December 27, 2020, the Economic Aid Act was signed into law. This second coronavirus relief package granted additional funds for a new round of PPP loans. Additionally, it expands the eligibility for loans and allows certain businesses to request a second loan. The SBA began accepting applications for the second round of PPP loans on January 13, 2021, and we accepted new applications through April 6, 2021. During the six months ended June 30, 2021, we originated $112.3 million of additional PPP loans under this second round of PPP loans. At June 30, 2021, we had $132.1 million of approved PPP loans outstanding.
Additionally, we assisted both our consumer and commercial borrowers that experienced financial hardship due to COVID-19 related challenges. As of June 30, 2021, we had two remaining loans with payment deferrals totaling $182,000, a decrease from $326.0 million reported in our second quarter earnings release in July 2020. As of July 26, 2021, we had a 1-4 family residential loan outstanding of $158,000 with payment deferrals. The decrease in the COVID-19 modified loans are the result of the loans coming out of the deferral periods and resuming performance.
Operating Results
Net income decreased $237,000, or 1.1%, for the three months ended June 30, 2021, to $21.3 million compared to the same period in 2020. The decrease was a result of the $5.9 million decrease in interest income, the $1.3 million decrease in noninterest income and the increase in noninterest expense of $843,000, partially offset by the $4.3 million decrease in interest expense and the $3.6 million decrease in provision for credit losses. Earnings per diluted common share were $0.65 for the three months ended June 30, 2021 and 2020.

During the six months ended June 30, 2021, our net income increased $29.9 million, or 117.2%, to $55.4 million from $25.5 million for the same period in 2020. The increase in net income was a direct result of a reversal of provision for credit losses of $8.5 million compared to a large build-up in the allowance for credit losses of $30.5 million in the same period in 2020. The decrease in the provision was primarily due to an improved economic forecast since the second quarter of 2020 and its effect on macroeconomic factors used in the CECL model. This was partially offset by the $4.3 million increase in income tax expense, the $3.1 million decrease in noninterest income and the $1.6 million increase in noninterest expense. Earnings per diluted common share increased $0.93, or 122.4%, to $1.69 for the six months ended June 30, 2021, from $0.76 for the same period in 2020.
Financial Condition
Our total assets increased $174.2 million, or 2.5%, to $7.18 billion at June 30, 2021 from $7.01 billion at December 31, 2020. Our securities portfolio increased by $164.6 million, or 6.1%, to $2.86 billion, compared to $2.70 billion at December 31, 2020. The increase in our securities portfolio was comprised of an increase of $364.0 million in investment securities, partially offset by a decrease of $199.4 million in MBS, as the composition of the securities portfolio continued to change as municipal and corporate bonds and, to a lesser extent, U.S. Treasury Notes increased while MBS decreased. Our FHLB stock increased $2.8 million, or 11.2%, to $28.1 million from $25.3 million at December 31, 2020, primarily due to increases in the amount of FHLB stock we were required to hold in relation to our FHLB borrowings.
Loans decreased $15.4 million, or 0.4%, to $3.64 billion at June 30, 2021 from $3.66 billion at December 31, 2020. The net decrease in our loan portfolio was comprised of decreases of $59.6 million of commercial loans, $53.8 million of construction loans, $41.6 million of 1-4 family residential loans and $4.0 million of loans to individuals, partially offset by increases of $135.2 million of commercial real estate loans and $8.4 million of municipal loans. Our PPP loans, a component of the commercial loan category, experienced a decrease of $82.7 million, or 38.5%, to $132.1 million as of June 30, 2021, from $214.8 million at December 31, 2020, due to forgiveness payments received from loans funded under the CARES Act. Loans held for sale decreased $1.2 million, or 32.1%, to $2.5 million at June 30, 2021 from $3.7 million at December 31, 2020.
Our nonperforming assets at June 30, 2021 decreased $2.2 million, or 12.6%, to $15.3 million and represented 0.21% of total assets, compared to $17.5 million, or 0.25% of total assets at December 31, 2020.  Nonaccruing loans decreased $2.6 million, or 33.2%, to $5.2 million, and the ratio of nonaccruing loans to total loans decreased to 0.14% at June 30, 2021 compared to 0.21% at December 31, 2020.  Restructured loans were $9.5 million at June 30, 2021, a decrease of 1.0%, from $9.6 million at December 31, 2020. OREO increased to $566,000 at June 30, 2021 from $106,000 at December 31, 2020. 
Our deposits increased $223.8 million, or 4.5%, to $5.16 billion at June 30, 2021 from $4.93 billion at December 31, 2020, which was comprised of an increase of $146.3 million in noninterest bearing deposits and $77.5 million in interest bearing deposits. The increase was largely driven by PPP loan disbursements and stimulus checks deposited during the first half of 2021. Brokered deposits decreased $80.5 million, or 58.3%, for the six months ended June 30, 2021.
Total FHLB borrowings decreased $111.2 million, or 13.4%, to $721.4 million at June 30, 2021 from $832.5 million at December 31, 2020.
Our total shareholders’ equity at June 30, 2021 increased 2.2%, or $19.1 million, to $894.4 million, or 12.5% of total assets, compared to $875.3 million, or 12.5% of total assets, at December 31, 2020. The increase in shareholders’ equity was the result of net income of $55.4 million, net issuance of common stock under employee stock plans of $5.8 million, stock compensation expense of $1.4 million and common stock issued under our dividend reinvestment plan of $662,000. These increases were partially offset by cash dividends paid of $21.3 million, the repurchase of $18.7 million of our common stock and other comprehensive loss of $4.2 million.
Economic conditions were significantly impacted by the COVID-19 pandemic in 2020; however, Texas still outperformed the nation in 2020, and our Fort Worth and Austin market areas have continued to perform generally better than many other parts of the country. Texas continues to experience economic growth due to in-migration from other states and company relocation from other states, although such growth is difficult to predict and remains uncertain.
Key financial indicators management follows include, but are not limited to, numerous interest rate sensitivity and interest rate risk indicators, credit risk, operations risk, liquidity risk, capital risk, regulatory risk, competition risk, yield curve risk, U.S. agency MBS prepayment risk and economic risk indicators.

Balance Sheet Strategy
We utilize wholesale funding and securities to enhance our profitability and balance sheet composition by determining acceptable levels of credit, interest rate and liquidity risk consistent with prudent capital management.  This balance sheet strategy consists of borrowing a combination of long- and short-term funds from the FHLB, the FRDW or the brokered funds market. These funds are invested primarily in U.S. agency MBS and long-term municipal securities.  Although U.S. agency MBS often carry lower yields than traditional mortgage loans and other types of loans we make, these securities generally (i) increase the overall quality of our assets because of either the implicit or explicit guarantees of the U.S. Government, (ii) are more liquid than individual loans and (iii) may be used to collateralize our borrowings or other obligations.  While the strategy of investing a portion of our assets in U.S. Agency MBS and municipal securities has historically resulted in lower interest rate spreads and margins, we believe the lower operating expenses and reduced credit risk, combined with the managed interest rate risk of this strategy, have enhanced our overall profitability for many years.  At this time, we utilize this balance sheet strategy with the goal of enhancing overall profitability by maximizing the use of our capital.
Risks associated with the asset structure we maintain include a lower net interest rate spread and margin when compared to our peers, changes in the slope of the yield curve, which can reduce our net interest rate spread and margin, increased interest rate risk, the length of interest rate cycles, changes in volatility or spreads associated with the MBS and municipal securities, the unpredictable nature of MBS prepayments and credit risks associated with the municipal securities.  See “Part I - Item 1A.  Risk Factors – Risks Related to Our Business” in the 2020 Form 10-K for a discussion of risks related to interest rates.  Our asset structure, net interest spread and net interest margin require us to closely monitor our interest rate risk. An additional risk is the change in fair value of the AFS securities portfolio as a result of changes in interest rates.  Significant increases in interest rates, especially long-term interest rates, could adversely impact the fair value of the AFS securities portfolio, which could also significantly impact our equity capital.  Due to the unpredictable nature of MBS prepayments, the length of interest rate cycles and the slope of the interest rate yield curve, net interest income could fluctuate more than simulated under the scenarios modeled by our ALCO and described under “Item 3.  Quantitative and Qualitative Disclosures about Market Risk” in this Quarterly Report on Form 10-Q.
Determining the appropriate size of the balance sheet is one of the critical decisions any bank makes.  Our balance sheet is not merely the result of a series of micro-decisions, but rather the size is controlled based on the economics of assets compared to the economics of funding and funding sources. The low interest rate environment and economic landscape requires that we monitor the interest rate sensitivity of the assets driving our growth and closely align ALCO objectives accordingly.
The management of our securities portfolio as a percentage of earning assets is guided by the current economics associated with the securities portfolio, changes in our overall loan and deposit levels and changes in our wholesale funding levels.  Our balance sheet strategy is designed such that our securities portfolio should help mitigate financial performance associated with potential business and economic cycles that include slower loan growth and higher credit costs.
Our investment securities and U.S. Agency MBS increased from $2.70 billion at December 31, 2020 to $2.86 billion at June 30, 2021. The increase in the securities portfolio was in conjunction with our balance sheet strategy and ALCO objectives.
During the first half of 2021, the composition of the securities portfolio continued to change as municipal bonds, U.S. Treasury Notes and corporate bonds increased while MBS decreased. The decrease in MBS was attributable to higher MBS prepayment speeds due to the significantly low interest rate environment that was slightly offset by MBS purchases. During the first half of 2021, we increased security purchases when compared to the latter half of 2020, including $334.0 million in highly-rated primarily Texas municipal securities, $174.2 million of which were taxable, $35.3 million in investment grade subordinated debt, $13.1 million in U.S. Agency MBS, and $52.3 million in U.S. Treasury Notes. We sold approximately $35.1 million tax-free AFS electric utility revenue municipals due to uncertainty caused by the severe winter storm in Texas during February. We also sold $9.6 million in U.S. Treasury Notes. Sales of AFS securities for the three and six months ended June 30, 2021, resulted in a net realized gain of $15,000 and $2.0 million, respectively.
At June 30, 2021, securities as a percentage of assets totaled 39.8%, compared to 38.5% at December 31, 2020, due to the $164.6 million, or 6.1%, increase in the securities portfolio. Our balance sheet management strategy is dynamic and is continually evaluated as market conditions warrant.  As interest rates, yield curves, MBS prepayments, funding costs, security spreads and loan and deposit portfolios change, our determination of the proper types, amount and maturities of securities to invest in, as well as funding needs and funding sources, will continue to be evaluated.  Should the economics of purchasing securities decrease, we may allow the securities portfolio to shrink through run-off or security sales. However, should the economics become more attractive, we may strategically increase the securities portfolio and the balance sheet.
With respect to liabilities, we continue to primarily utilize a combination of deposits and FHLB borrowings to achieve our strategy of minimizing cost while achieving overall interest rate risk objectives as well as the liability management objectives of

the ALCO. Our primary wholesale funding source is FHLB borrowings and to a lesser extent we utilize federal funds purchased, the FRDW and brokered deposits.
For the six months ended June 30, 2021, our total wholesale funding as a percentage of deposits, not including brokered deposits, decreased to 15.3% from 20.2% at December 31, 2020, and 30.1% at June 30, 2020. The decrease from both of the prior year periods was due to the increase in our deposits and the decreases in FHLB borrowings and brokered deposits.
Our FHLB borrowings decreased 13.4%, or $111.2 million, to $721.4 million at June 30, 2021 from $832.5 million at December 31, 2020. In connection with our borrowings, the Bank has entered into various variable rate agreements and fixed rate short-term pay agreements. These agreements totaled $605.0 million and $670.0 million at June 30, 2021 and December 31, 2020, respectively. Six of the agreements have an interest rate tied to three-month LIBOR and the remaining agreements have interest rates tied to one-month LIBOR. In connection with all agreements outstanding on June 30, 2021, the Bank also entered into various interest rate swap contracts that are treated as cash flow hedges under ASC Topic 815, “Derivatives and Hedging” that are expected to be effective in hedging the variability in future cash flows attributable to fluctuations in the underlying LIBOR interest rate. The interest rate swap contracts had an average interest rate of 1.14% with an average weighted maturity of 3.7 years at June 30, 2021. These transactions are reevaluated on a monthly basis to determine if the hedged forecasted transactions are still probable of occurring. If at a subsequent evaluation, it is determined that the transactions will not occur, any related gains or losses recorded in AOCI are immediately recognized in earnings. Refer to “Note 9 – Derivative Financial Instruments and Hedging Activities” in our consolidated financial statements included in this report for a detailed description of our hedging policy and methodology related to derivative instruments.     
Our brokered CDs decreased $80.5 million, or 78.2%, from $102.8 million at December 31, 2020 to $22.4 million at June 30, 2021. At June 30, 2021, our brokered CDs had a weighted average cost of 27 basis points and remaining maturities of less than 13 months. To provide management flexibility in managing the interest rate risk of wholesale funding, the ALCO has approved up to $50.0 million to issue brokered deposits to replace those maturing within 30 days. Our wholesale funding policy allows for maximum brokered deposits of $450.0 million. This brokered deposit maximum limit could increase or decrease depending on changes in ALCO objectives. Potential higher interest expense and lack of customer loyalty are risks associated with the use of brokered CDs.
On November 6, 2020, the Company issued $100.0 million in aggregate principal amount of fixed-to-floating rate subordinated notes that mature on November 15, 2030. Refer to “Note 7 – Long-term Debt” in our consolidated financial statements included in this report for a detailed description of the terms of the subordinated notes.

Results of Operations
Our results of operations are dependent primarily on net interest income, which is the difference between the interest income earned on assets (loans and investments) and interest expense due on our funding sources (deposits and borrowings) during a particular period.  Results of operations are also affected by our noninterest income, provision for credit losses, noninterest expenses and income tax expense.  General economic and competitive conditions, particularly changes in interest rates, changes in interest rate yield curves, prepayment rates of MBS and loans, repricing of loan relationships, government policies and actions of regulatory authorities also significantly affect our results of operations.  Future changes in applicable law, regulations or government policies may also have a material impact on us. The adoption of CECL and the COVID-19 pandemic significantly impacted our results of operations in 2020 and may continue to impact our results of operations for the remainder of 2021.

Net Interest Income
Net interest income is one of the principal sources of a financial institution’s earnings stream and represents the difference or spread between interest and fee income generated from interest earning assets and the interest expense paid on interest bearing liabilities.  Fluctuations in interest rates or interest rate yield curves, as well as repricing characteristics and volume and changes in the mix of interest earning assets and interest bearing liabilities, materially impact net interest income. During the first quarter of 2020, the Federal Reserve reduced target federal funds rate by 150 basis points to 25 basis points.
Net interest income for the three months ended June 30, 2021 decreased $1.6 million, or 3.4%, compared to the same period in 2020. The decrease in net interest income for the three months ended June 30, 2021 was due to the decrease in interest income, a result of a decrease in the average yield on our interest earning assets, partially offset by the decrease in interest expense on our interest bearing liabilities due to the overall decline in interest rates. Total interest income decreased $5.9 million, or 10.1%, to $52.6 million for the three months ended June 30, 2021, compared to $58.5 million during the same period in 2020. Total interest expense decreased $4.3 million, or 38.2%, to $6.9 million for the three months ended June 30, 2021, compared to $11.2 million for the same period in 2020. Our net interest margin (FTE), a non-GAAP measure, increased to 3.06% for the three months ended June 30, 2021, compared to 3.02% for the same period in 2020 and our net interest spread (FTE), also a non-GAAP measure, increased to 2.89%, compared to 2.82% for the same period in 2020.
Net interest income was $92.0 million for the six months ended June 30, 2021 and 2020, with the decrease in interest income offset by the decrease in interest expense on our interest bearing liabilities, both a result of an overall decline in interest rates. Total interest income decreased $13.1 million, or 11.0%, to $106.2 million for the six months ended June 30, 2021, compared to $119.2 million for the same period in 2020. Total interest expense decreased $13.1 million, or 47.9%, to $14.2 million for the six months ended June 30, 2021, compared to $27.3 million for the same period in 2020. Our net interest margin (FTE), a non-GAAP measure, increased to 3.13% for the six months ended June 30, 2021, compared to 3.02% for the same period in 2020,

and our net interest spread (FTE), also a non-GAAP measure, increased to 2.96%, compared to 2.79% for the same period in 2020. See “Non-GAAP Financial Measures” for more information and for a reconciliation to GAAP.
Quarterly Analysis of Changes in Interest Income and Interest Expense
The following table presents on a fully taxable-equivalent basis, a non-GAAP measure, the net change in net interest income and sets forth the dollar amount of increase (decrease) in the average volume of interest earning assets and interest bearing liabilities and from changes in yields/rates. Volume/Yield/Rate variances (change in volume times change in yield/rate) have been allocated to amounts attributable to changes in volumes and to changes in yields/rates in proportion to the amounts directly attributable to those changes (in thousands):

(1)Interest yields on loans and securities that are nontaxable for federal income tax purposes are presented on a fully taxable-equivalent basis. See “Non-GAAP Financial Measures” for more information and for a reconciliation to GAAP.
The decrease in total interest income was attributable to the decrease in the average yield on interest earning assets to 3.49% for the three months ended June 30, 2021 from 3.69% for the same period in 2020, and by the mix of average interest earning assets for the three months ended June 30, 2021, when compared to the same period in 2020. The decrease in the average yield on total earning assets during the three months ended June 30, 2021 was a result of decreases in the short-term interest rate yield curve during the first half of 2021 and the tightening credit spreads that occurred primarily during the last half of 2020 and into the first half of 2021. For the three months ended June 30, 2021, average earning assets decreased $301.0 million, or 4.5%, when compared to the same period in 2020.
The decrease in total interest expense for the three months ended June 30, 2021 was attributable to an overall decline in interest rates paid on total interest bearing liabilities to 0.60% for the three months ended June 30, 2021 from 0.87% for the same period in 2020, and the decrease in average interest bearing liabilities.

(1)Interest yields on loans and securities that are nontaxable for federal income tax purposes are presented on a fully taxable-equivalent basis. See “Non-GAAP Financial Measures” for more information and for a reconciliation to GAAP.
The decrease in total interest income was attributable to the decrease in the average yield on earning assets to 3.58% for the six months ended June 30, 2021 from 3.87% for the same period in 2020, and a decrease in average earning assets of $153.7 million, or 2.4%. The decrease in the average yield on total earning assets during the six months ended June 30, 2021 was a result of decreases in the short-term interest rate yield curve during the first half of 2021 and the tightening credit spreads that occurred primarily during the last half of 2020 and into the first half of 2021. The decrease in average earning assets was primarily the result of a decrease in MBS and loans, partially offset by an increase in investment securities.
The decrease in total interest expense for the six months ended June 30, 2021 was attributable to an overall decline in interest rates paid on total interest bearing liabilities to 0.62% for the six months ended June 30, 2021 from 1.08% for the same period in 2020, and the decrease in average interest bearing liabilities.

The 10.3% decrease in noninterest income for the three months ended June 30, 2021, when compared to the same period in 2020, was due to decreases in net gain on sale of securities AFS and gain on sale of loans, partially offset by increases in deposit services income, brokerage services income and trust fees. The 11.3% decrease in noninterest income for the six months ended June 30, 2021, when compared to the same period in 2020, was due to the decrease in net gain on sale of securities AFS, partially offset by increases in other noninterest income, deposit services income, gain on sale of loans, brokerage services income and trust fees.
The increase in deposit services income for the three months ended June 30, 2021, when compared to the same period in 2020, was primarily the result of increases in debit card income, overdraft income and service charges on commercial deposit accounts. The increase for the six months ended June 30, 2021, when compared to the same period in 2020, was primarily the result of increases in debit card income and service charges on commercial deposit accounts, partially offset by a decrease in overdraft income due to an increase in funds available to customers through government issued stimulus checks and PPP loans. The increase in debit card income was the result of an increase in debit card transactions for the three and six months ended June 30, 2021.
During the three and six months ended June 30, 2021, we sold municipal securities and U.S. Treasury securities that resulted in a net gain on sale of AFS securities of $15,000 and $2.0 million, respectively.
Gain on sale of loans decreased for the three months ended June 30, 2021, and increased for the six months ended June 30, 2021, when compared to the same periods in 2020. Overall mortgage loan production increased during 2020 and into 2021 as a result of lower interest rates, however, the volume of loans sold decreased for the three months ended June 30, 2021, when compared to the same period in 2020, primarily due to the competitive mortgage loan market.
Trust fees increased for the three and six months ended June 30, 2021, when compared to the same periods in 2020, due to an increase in assets under management. The market value of our wealth management and trust assets under management, which

are not reflected in our consolidated balance sheets, increased 10.6%, and were approximately $1.63 billion at June 30, 2021, compared to $1.47 billion at June 30, 2020.
Brokerage services income increased for the three and six months ended June 30, 2021, when compared to the same periods in 2020, due to growth in our client base and recurring revenue.
Other noninterest income increased for the six months ended June 30, 2021, when compared to the same period in 2020, primarily due to increases in mortgage servicing fee income and swap fee income, partially offset by decreases in mortgage derivative income.

The increase in noninterest expense for the three months ended June 30, 2021, when compared to the same period in 2020, was the result of increases in salaries and employee benefits, FDIC insurance and advertising, travel and entertainment expense, partially offset by decreases in other noninterest expense and amortization of intangibles. The increase for the six months ended June 30, 2021, when compared to the same period in 2020, was the result of increases in salaries and employee benefits and FDIC insurance, partially offset by decreases in other noninterest expense and amortization of intangibles.
Salaries and employee benefits increased for the three and six months ended June 30, 2021, when compared to the same periods in 2020, due to increases in health insurance expense and direct salary expense, partially offset by a decrease in retirement expense.
Southside Bancshares, Inc. |58

Table of Contents

Health and life insurance expense, included in salaries and employee benefits, increased $949,000, or 64.9%, and $721,000, or 19.8%, for the three and six months ended June 30, 2021, respectively, when compared to the same periods in 2020. We have a self-insured health plan which is supplemented with a stop loss insurance policy. Health insurance costs are rising nationwide and these costs may increase during the remainder of 2021.
For the three and six months ended June 30, 2021, direct salary expense increased $705,000, or 4.4%, and $1.41 million, or 4.4%, respectively, when compared to the same periods in 2020, primarily due to normal salary increases effective in the first quarter of 2021, as well as increases in brokerage service commissions.
Retirement expense, included in salaries and employee benefits, decreased $279,000, or 21.1%, and $359,000, or 14.8%, for the three and six months ended June 30, 2021, respectively, when compared to the same periods in 2020. The decrease was due to the freeze of the Retirement Plan and Restoration Plan to further benefit accruals as of December 31, 2020, which resulted in no defined benefit plan service cost expense in the first half of 2021. This decrease was partially offset by increases in our split dollar agreement expense and ESOP expense.
Advertising, travel and entertainment expense decreased for the six months ended June 30, 2021, when compared to the same period in 2020, primarily due to decreases in travel, meals and entertainment, and registration fees due to reduced activity resulting from COVID-19 travel restrictions, when compared to the same period in 2020. Donations, included in advertising, travel and entertainment, also decreased for the six months ended June 30, 2021, when compared to the same period in 2020. As travel restrictions were lifted in the first quarter of 2021, activity increased for the three months ended June 30, 2021, when compared to the same period in 2020, which resulted in increases in travel, meals and entertainment and registration fees. Donations and media advertising, included in advertising, travel and entertainment, also increased for the three months ended June 30, 2021, when compared to the same period in 2020.
ATM expense increased for the three and six months ended June 30, 2021, when compared to the same periods in 2020, due to higher ATM maintenance expense as new ATMs and ITMs were put into service and hardware upgrades were completed.
Professional fees decreased for the three and six months ended June 30, 2021, when compared to the same periods in 2020, due to a decrease in legal fees during the three months ended June 30, 2021, and due to several professional fees paid in connection with training, consulting and data conversion during the six months ended June 30, 2020.
Communications expense increased for the three and six months ended June 30, 2021, when compared to the same periods in 2020, driven by an increase in phone and internet costs.
FDIC insurance increased for the three and six months ended June 30, 2021, when compared to the same periods in 2020, due to a small bank assessment credit issued by the FDIC and utilized in the first half of 2020.
Amortization of intangibles decreased for the three and six months ended June 30, 2021, when compared to the same periods in 2020, due primarily to a decrease in core deposit intangible amortization which is recognized on an accelerated method resulting in a decline in expense over time.
Other noninterest expense decreased for the three and six months ended June 30, 2021, when compared to the same periods in 2020, primarily due to a decrease in retirement expense related to the Retirement Plan and the Restoration Plan, partially offset by an increase in computer supplies expense.

Income Taxes
Pre-tax income for the three and six months ended June 30, 2021 was $24.2 million and $63.0 million, respectively, a decrease of 0.7%, and an increase of 118.9%, compared to $24.4 million and $28.8 million for the same periods in 2020. We recorded income tax expense of $2.9 million and $7.6 million for the three and six months ended June 30, 2021, respectively, compared to income tax expense of $2.8 million and $3.3 million for the same periods in 2020. The ETR as a percentage of pre-tax income was 11.9% and 12.1% for the three and six months ended June 30, 2021, respectively, compared to an ETR as a percentage of pre-tax income of 11.5% and 11.4% for the same periods in 2020. The higher ETR for the six months ended June 30, 2021 was primarily due to a decrease in tax-exempt income as a percentage of pre-tax income as compared to the same period in 2020.
The ETR differs from the statutory rate of 21% for the three and six months ended June 30, 2021 and 2020 primarily due to the effect of tax-exempt income from municipal loans and securities, as well as BOLI. The net deferred tax liability totaled $16.5 million at June 30, 2021, compared to $15.5 million at December 31, 2020. The increase in the net deferred tax liability is primarily the result of the increase in unrealized gains in the AFS securities portfolio.
See “Note 11 – Income Taxes” to our consolidated financial statements included in this report. No valuation allowance was recorded at June 30, 2021 or December 31, 2020, as management believes it is more likely than not that all of the deferred tax asset items will be realized in future years.

Composition of Loans
One of our main objectives is to seek attractive lending opportunities in Texas, primarily in the market areas in which we operate. Refer to “Part I - Item 1. Business - Market Area” in the 2020 Form 10-K for a discussion of our primary market area and the geographic concentration of our loan portfolio as of December 31, 2020.  There were no substantial changes in these concentrations during the six months ended June 30, 2021.  The majority of our loan originations are made to borrowers who live in and/or conduct business in the market areas of Texas in which we operate or adjoin, with the exception of municipal loans, which are made primarily throughout the state of Texas.  Municipal loans are made to municipalities, counties, school districts and colleges.
The following table sets forth loan totals by class as of the dates presented (dollars in thousands):

Our loan portfolio decreased $15.4 million, or 0.4%, at June 30, 2021 compared to December 31, 2020, with decreases in commercial loans, construction loans, 1-4 family residential loans and loans to individuals, partially offset by increases in commercial real estate and municipal loans. For the six months ended June 30, 2021, our PPP loans experienced a net decrease of $82.7 million, or 38.5%, from $214.8 million at December 31, 2020, primarily due to forgiveness payments received from loans funded under the CARES Act.
Our loan portfolio decreased $210.2 million, or 5.5%, at June 30, 2021 compared to June 30, 2020, with decreases in commercial loans, 1-4 family residential loans, construction loans and loans to individuals, partially offset by increases in municipal loans and commercial real estate loans.
At June 30, 2021, our real estate loans represented 72.4% of our loan portfolio and were comprised of commercial real estate loans of 54.3%, 1-4 family residential loans of 25.7% and construction loans of 20.0%. Commercial real estate loans primarily include loans collateralized by retail, commercial office buildings, multi-family residential buildings, medical facilities and offices, senior living, assisted living and skilled nursing facilities, warehouse facilities, hotels and churches. Our 1-4 family residential loans consist primarily of loans secured by first mortgages on owner occupied 1-4 family residences. Our construction loans are collateralized by property located primarily in or near the market areas we serve. A number of our construction loans will be owner occupied upon completion. Construction loans for non-owner occupied projects are financed, but these typically have cash flows from leases with tenants, secondary sources of repayment, and in some cases, additional collateral.
Loan Portfolios Most at Risk due to Economic Stress Resulting from Impact of COVID-19
The banking industry is affected by general economic conditions such as interest rates, inflation, recession, unemployment and other factors beyond our control, including the impact of the COVID-19 pandemic.  During the last 30 years the Texas economy has continued to diversify, decreasing the overall impact of fluctuations in oil and gas prices; however, the oil and gas industry is still a significant component of the Texas economy. Oil prices have experienced a recovery during the six months ended June 30, 2021 following a significant reduction primarily reflective of the economic impact of COVID-19. We cannot predict whether current economic conditions or oil prices will improve, remain the same or decline.
As of June 30, 2021, the Company’s exposure to the oil and gas industry totaled $94.3 million, or 2.59% of gross loans, a decrease of $10.3 million from December 31, 2020, and consisted primarily of (i) support/service loans of 1.82%, (ii) upstream of 0.60%, (iii) midstream of 0.11%, and (iv) downstream of 0.06%. Expanded monitoring and analysis of these loans has been implemented to address the uncertainty in oil and gas prices as needed.

The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains and increased unemployment levels. The resulting temporary closure of many businesses and the implementation of social distancing and sheltering in place policies impacted and could continue to impact many of our customers. As of June 30, 2021, most businesses in Texas are re-opened without restrictions. Commercial activity has improved but has not returned to the levels existing prior to the outbreak of the pandemic. In addition to the oil and gas industry, we consider the sectors set forth in the below table to be most vulnerable to financial risks from business disruptions caused by the pandemic mitigation efforts based on North American Industry Classification System categories as of June 30, 2021 (dollars in thousands). We recognize that these industries may take longer to recover as consumers may be hesitant to return to full social interaction or may change their spending habits on a more permanent basis as a result of the pandemic. We continue to monitor these customers closely.

Allowance for Credit Losses - Loans
In accordance with ASC 326, the allowance for credit losses on loans is estimated and recognized upon origination of the loan based on expected credit losses. The CECL model uses historical experience and current conditions for homogeneous pools of loans, and reasonable and supportable forecasts about future events. The impact of varying economic conditions and portfolio stress factors are a component of the credit loss models applied to each portfolio. Reserve factors are specific to the loan segments that share similar risk characteristics based on the probability of default assumptions and loss given default assumptions, over the contractual term. The forecasted periods gradually mean-revert the economic inputs to their long-run historical trends. Management evaluates the economic data points used in the Moody’s forecasting scenarios on a quarterly basis to determine the most appropriate impact to the various portfolio characteristics based on management’s view and applies weighting to various forecasting scenarios as deemed appropriate based on known and expected economic activities. Management also considers and may apply relevant qualitative factors, not previously considered, to determine the appropriate allowance level. The use of the CECL model includes significant judgment by management and may differ from those of our peers due to different historical loss patterns, economic forecasts, and the length of time of the reasonable and supportable forecast period and reversion period.
We utilize Moody’s Analytics economic forecast scenarios and assign probability weighting to those scenarios which best reflect management’s views on the economic forecast. The probability weighting and scenarios utilized for the estimate of the allowance were generally reflective of an improved economic forecast as based on known and knowable information as of June 30, 2021.
When determining the appropriate allowance for credit losses on our loan portfolio, our commercial construction and real estate loans, commercial loans and municipal loans utilize the probability of default/loss given default discounted cash flow approach. Reserves on these loans are based upon risk factors including the loan type and structure, collateral type, leverage ratio, refinancing risk and origination quality, among others. Our consumer construction real estate loans, 1-4 family residential loans and our loans to individuals use a loss rate based upon risk factors including loan types, origination year and credit scores. Loans covered by the PPP may be eligible for loan forgiveness. The remaining loan balance after forgiveness of any amount is still fully guaranteed by the SBA and therefore does not have an associated allowance.
Loans evaluated collectively in a pool are monitored to ensure they continue to exhibit similar risk characteristics with other loans in the pool. If a loan does not share similar risk characteristics with other loans, expected credit losses for that loan are evaluated individually.
As of June 30, 2021, our review of the loan portfolio indicated that an allowance for loan losses of $42.9 million was appropriate to cover expected losses in the portfolio.  Changes in economic and other conditions, including the application of the CECL model and the economic uncertainty related to COVID-19, may require future adjustments to the allowance for loan losses.
During the six months ended June 30, 2021, the allowance for loan losses decreased $6.1 million, or 12.4%, to $42.9 million, or 1.18% of total loans, when compared to $49.0 million, or 1.34% of total loans at December 31, 2020. The decrease in the allowance for credit losses for the first half of 2021 was primarily reflective of an improved economic forecast based on known and knowable information as of June 30, 2021.
For the three and six months ended June 30, 2021, loan charge-offs were $527,000 and $1.3 million, respectively, and recoveries were $466,000 and $1.1 million, respectively. For the three and six months ended June 30, 2020, loan charge-offs were $546,000 and $1.5 million, respectively, and recoveries were $436,000 and $887,000, respectively. For the three months ended June 30, 2021, we recorded a provision for credit losses for loans of $1.5 million, a decrease of $4.8 million, or 76.0%,

from a provision of $6.3 million for the three months ended June 30, 2020. For the six months ended June 30, 2021, we recorded a reversal of provision of $5.9 million, compared to a provision of $30.4 million for the six months ended June 30, 2020. The decrease during the six months ended June 30, 2021, was primarily due to improvement in the economic forecast since the second quarter of 2020 and its effect on macroeconomic factors used in the CECL model. The provision in the first half of 2020 was due to the estimated economic impact of COVID-19 on the macroeconomic factors, including the potential for credit deterioration.
PCD Loans
We have purchased certain loans that as of the date of purchase have experienced more-than-insignificant deterioration in credit quality since origination. Management evaluates these loans against a probability threshold to determine if substantially all of the contractually required payments will be received. PCD loans are recorded at the purchase price plus an allowance for credit losses which becomes the PCD loan's initial amortized cost. The non-credit related discount or premium, the difference between the initial amortized cost and the par value, will be amortized into interest income over the life of the loan. Any further changes to the allowance for credit losses are recorded through provision expense. In accordance with the adoption of ASU 2016-13, management did not reassess whether PCI assets met the criteria of PCD assets and elected to not maintain pools of loans as of the date of adoption. All PCD loans are evaluated based upon product type within the underlying segment.
Nonperforming Assets
Nonperforming assets consist of delinquent loans 90 days or more past due, nonaccrual loans, OREO, repossessed assets and TDR loans.  Nonaccrual loans are loans 90 days or more delinquent and collection in full of both the principal and interest is not expected.  Additionally, some loans that are not delinquent or that are delinquent less than 90 days may be placed on nonaccrual status if it is probable that we will not receive contractual principal and interest payments in accordance with the terms of the respective loan agreements.  When a loan is categorized as nonaccrual, the accrual of interest is discontinued and any accrued balance is reversed for financial statement purposes.  OREO represents real estate taken in full or partial satisfaction of debts previously contracted.  The dollar amount of OREO is based on a current evaluation of the OREO at the time it is recorded on our books, net of estimated selling costs.  Updated valuations are obtained as needed and any additional impairments are recognized.  Restructured loans represent loans that have been renegotiated to provide a below market interest rate or deferral of interest or principal because of deterioration in the financial position of the borrowers.  The restructuring of a loan is considered a TDR if both (i) the borrower is experiencing financial difficulties and (ii) the creditor has granted a concession.  Concessions may include interest rate reductions or below market interest rates, restructuring amortization schedules and other actions intended to minimize potential losses.  Categorization of a loan as nonperforming is not in itself a reliable indicator of potential loan loss.  Other factors, such as the value of collateral securing the loan and the financial condition of the borrower are considered in judgments as to potential loan loss.

Liquidity and Interest Rate Sensitivity
Liquidity management involves our ability to convert assets to cash with minimum risk of loss while enabling us to meet our obligations to our customers at any time.  This means addressing (1) the immediate cash withdrawal requirements of depositors and other fund providers; (2) the funding requirements of lines and letters of credit; and (3) the short-term credit needs of customers.  Liquidity is provided by cash, interest earning deposits and short-term investments that can be readily liquidated with a minimum risk of loss.  At June 30, 2021, these investments were 6.5% of total assets, as compared with 7.4% for both December 31, 2020 and June 30, 2020. The decrease to 6.5% at June 30, 2021 as compared to December 31, 2020, is reflective of the increase in total assets combined with the decrease in the short-term investment portfolio. Liquidity is further provided through the matching, by time period, of rate sensitive interest earning assets with rate sensitive interest bearing liabilities.  The Bank has three unsecured lines of credit for the purchase of overnight federal funds at prevailing rates with Frost Bank, TIB – The Independent Bankers Bank and Comerica Bank for $40.0 million, $15.0 million and $7.5 million, respectively. There were no federal funds purchased at June 30, 2021 or December 31, 2020.  To provide more liquidity in response to the economic impact of the COVID-19 pandemic, the Federal Reserve took steps to encourage broader use of the discount window. At June 30, 2021, the amount of additional funding the Bank could obtain from the FRDW, collateralized by securities, was approximately $487.7 million. There were no borrowings from the FRDW at June 30, 2021 or December 31, 2020. At June 30, 2021, the amount of additional funding Southside Bank could obtain from FHLB, collateralized by securities, FHLB stock and nonspecified loans and securities, was approximately $1.23 billion, net of FHLB stock purchases required.  The Bank has a $5.0 million line of credit with Frost Bank to be used to issue letters of credit, and at June 30, 2021, the line had one outstanding letter of credit for $91,000. The Bank currently has no outstanding letters of credit from FHLB held as collateral for its public fund deposits.
Management continually evaluates our liquidity position and currently believes the Company has adequate funding to meet our financial needs. During March 2020, in response to COVID-19, the Federal Reserve lowered the primary credit rate by 150 basis points to 0.25 percent and extended terms to 90 days to enhance market liquidity and encourage use of the discount window. In addition, the Federal Reserve announced it would begin quantitative easing, or large-scale asset purchases, consisting primarily of U.S. Treasury securities and MBS to stem the effects of the pandemic on the financial markets. Failure to continue to contain the COVID-19 pandemic could cause a widespread liquidity crisis, and the availability of these funds or the options to sell securities currently held could be hindered.
Interest rate sensitivity management seeks to avoid fluctuating net interest margins and to enhance consistent growth of net interest income through periods of changing interest rates.  The ALCO closely monitors various liquidity ratios and interest rate spreads and margins.  The ALCO utilizes a simulation model to perform interest rate simulation tests that apply various interest rate scenarios including immediate shocks and MVPE to assist in determining our overall interest rate risk and the adequacy of our liquidity position.  In addition, the ALCO utilizes this simulation model to determine the impact on net interest income of various interest rate scenarios.  By utilizing this technology, we can determine changes that need to be made to the asset and liability mix to minimize the change in net interest income under these various interest rate scenarios.

Capital Resources
Our total shareholders’ equity at June 30, 2021 increased 2.2%, or $19.1 million, to $894.4 million, or 12.5% of total assets, compared to $875.3 million, or 12.5% of total assets, at December 31, 2020. The increase in shareholders’ equity was the result of net income of $55.4 million, net issuance of common stock under employee stock plans of $5.8 million, stock compensation expense of $1.4 million and common stock issued under our dividend reinvestment plan of $662,000. These increases were partially offset by cash dividends paid of $21.3 million, the repurchase of $18.7 million of our common stock and other comprehensive loss of $4.2 million.    
The Company’s Common Equity Tier 1 capital includes common stock and related paid-in capital, net of treasury stock, and retained earnings. The Bank’s Common Equity Tier 1 capital includes common stock and related paid-in capital, and retained earnings. In connection with the adoption of the Basel III Capital Rules, we elected to opt-out of the requirement to include accumulated other comprehensive income in Common Equity Tier 1. We also elected, for a five-year transitional period, the effects of credit loss accounting under CECL from Common Equity Tier 1, as further discussed below. Common Equity Tier 1 for both the Company and the Bank is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities.
Tier 1 capital includes Common Equity Tier 1 capital and additional Tier 1 capital. For the Company, additional Tier 1 capital at June 30, 2021 included $58.4 million of trust preferred securities. For bank holding companies that had assets of less than $15 billion as of December 31, 2009, trust preferred securities issued prior to May 19, 2010 can be treated as Tier 1 capital to the extent that they do not exceed 25% of Tier 1 capital after the application of capital deductions and adjustments. The Bank did not have any additional Tier 1 capital beyond Common Equity Tier 1 at June 30, 2021.

Total capital includes Tier 1 capital and Tier 2 capital. Tier 2 capital for both the Company and the Bank includes a permissible portion of the allowance for credit losses on loans and off-balance sheet exposures. Tier 2 capital for the Company also includes $197.3 million of qualified subordinated debt as of June 30, 2021. The permissible portion of qualified subordinated notes decreases 20% per year during the final five years of the term of the notes.
In April 2020, the FDIC, Federal Reserve, and the Office of the Comptroller of the Currency issued supplemental instructions allowing banking organizations that implement CECL before the end of 2020, the option to delay for two years an estimate of the CECL methodologies’ effect on regulatory capital, relative to the incurred loss methodologies effect on capital, followed by a three-year transition period.  We elected to adopt the five-year transition option. Accordingly, a CECL transitional amount totaling $10.4 million has been added back to CET1 as of June 30, 2021. The CECL transitional amount includes $7.8 million related to a cumulative effect of adopting CECL and $2.6 million related to the estimated incremental effect of CECL since adoption.
Also in April 2020, we began originating loans to qualified small businesses under the PPP administered by the SBA. Federal bank regulatory agencies have issued an interim final rule that permits banks to neutralize the regulatory capital effects of participating in the Paycheck Protection Program Lending Facility and clarify that PPP loans have a zero percent risk weight under applicable risk-based capital rules. Specifically, a bank may exclude all PPP loans pledged as collateral to the PPP Facility from its average total consolidated assets for the purposes of calculating its leverage ratio, while PPP loans that are not pledged as collateral to the PPP Facility will be included. Our PPP loans are included in the calculation of our leverage ratio as of June 30, 2021, as we did not utilize the PPP Facility for funding purposes.
Management believes that, as of June 30, 2021, we met all capital adequacy requirements to which we were subject. It is management’s intention to maintain our capital at a level acceptable to all regulatory authorities and future dividend payments will be determined accordingly.  Regulatory authorities require that any dividend payments made by either us or the Bank not exceed earnings for that year.  Accordingly, shareholders should not anticipate a continuation of the cash dividend payments simply because of the existence of a dividend reinvestment program.  The payment of dividends will depend upon future earnings, our financial condition and other related factors including the discretion of the board of directors.

Off-Balance-Sheet Arrangements, Commitments and Contingencies
Financial Instruments with Off-Balance-Sheet Risk. In the normal course of business, we are a party to certain financial instruments with off-balance-sheet risk to meet the financing needs of our customers. These off-balance-sheet instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount reflected in the financial statements. The contract or notional amounts of these instruments reflect the extent of involvement and exposure to credit loss that we have in these particular classes of financial instruments. The allowance for credit losses on these off-balance-sheet credit exposures is calculated using the same methodology as loans including conversion or usage factor to anticipate ultimate exposure and expected losses and is included in other liabilities on our consolidated balance sheets.

Allowance for off-balance-sheet credit exposures were as follows (in thousands):

Commitments to extend credit are agreements to lend to a customer provided that the terms established in the contract are met. Commitments to extend credit generally have fixed expiration dates and may require the payment of fees. Since some commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. These guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in commitments to extend credit and similarly do not necessarily represent future cash obligations.

We apply the same credit policies in making commitments to extend credit and standby letters of credit as we do for on-balance-sheet instruments.  We evaluate each customer’s creditworthiness on a case-by-case basis.  The amount of collateral obtained, if deemed necessary, upon extension of credit is based on management’s credit evaluation of the borrower.  Collateral held varies but may include cash or cash equivalents, negotiable instruments, real estate, accounts receivable, inventory, oil, gas and mineral interests, property, plant and equipment.
Leases. During the three months ended June 30, 2021, there were no operating lease ROU assets obtained in exchange for new operating lease liabilities. During the six months ended June 30, 2021, there were $1.1 million of operating lease ROU assets obtained in exchange for new operating lease liabilities, primarily due to one lease that commenced in January 2021 with an initial ROU asset of $1.1 million. During the three and six months ended June 30, 2020, there were $7.8 million and $8.0 million, respectively, of operating lease ROU assets obtained in exchange for new operating lease liabilities, primarily due to one lease that commenced in May 2020 with an initial ROU asset of $6.6 million.
Securities. In the normal course of business we buy and sell securities. At June 30, 2021, there were $41.9 million of unsettled trades to purchase securities and no unsettled trades to sell securities. At December 31, 2020, there were no unsettled trades to purchase securities and no unsettled trades to sell securities.
Deposits. There were no unsettled issuances of brokered CDs at June 30, 2021 or December 31, 2020.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The disclosures set forth in this item are qualified by the section captioned “Forward-Looking Statements” included in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this report and other cautionary statements set forth elsewhere in this Quarterly Report on Form 10-Q.
Refer to the discussion of market risks included in “Item 7A.  Quantitative and Qualitative Disclosures About Market Risk” in the 2020 Form 10-K.  
In the banking industry, a major risk exposure is changing interest rates.  The primary objective of monitoring our interest rate sensitivity, or risk, is to provide management the tools necessary to manage the balance sheet to minimize adverse changes in net interest income as a result of changes in the direction and level of interest rates.  Federal Reserve monetary control efforts, the effects of deregulation, economic uncertainty and legislative changes have been significant factors affecting the task of managing interest rate sensitivity positions in recent years.
In an attempt to manage our exposure to changes in interest rates, management closely monitors our exposure to interest rate risk through our ALCO.  Our ALCO meets regularly and reviews our interest rate risk position and makes recommendations to our board for adjusting this position.  In addition, our board reviews our asset/liability position on a monthly basis.  We primarily use two methods for measuring and analyzing interest rate risk: net income simulation analysis and MVPE modeling.  We utilize the net income simulation model as the primary quantitative tool in measuring the amount of interest rate risk associated with changing market rates.  This model quantifies the effects of various interest rate scenarios on projected net interest income and net income over the next 12 months.  The model is used to measure the impact on net interest income relative to a base case scenario of rates immediately increasing 100 and 200 basis points or decreasing 50 basis points over the next 12 months.  These simulations incorporate assumptions regarding balance sheet growth and mix, pricing and the repricing and maturity characteristics of the existing and projected balance sheet.  The impact of interest rate-related risks such as prepayment, basis and option risk are also considered.  The model has interest rate floors, and no interest rates are assumed to go negative. The interest rate environment declined during 2020 to a point where most treasury terms were under 100 basis points; therefore, we do not believe an analysis of an assumed decrease in interest rates beyond 50 basis points would provide meaningful results. We will continue to monitor interest rates, and we will resume the simulation of rates decreasing 100 and 200 basis points once rates begin to rise.
The following table reflects the noted increases and decreases in interest rates under the model simulations and the anticipated impact on net interest income relative to the base case over the next 12 months for the periods presented.

Decrease:
50 basis points(1.64)%(0.63)%
100 basis pointsN/A(2.19)%
200 basis pointsN/A(4.41)%
As part of the overall assumptions, certain assets and liabilities are given reasonable floors.  This type of simulation analysis requires numerous assumptions including but not limited to changes in balance sheet mix, prepayment rates on mortgage-related assets and fixed rate loans, cash flows and repricing of all financial instruments, changes in volumes and pricing, future shapes of the yield curve, relationship of market interest rates to each other (basis risk), credit spread and deposit sensitivity.  Assumptions are based on management’s best estimates but may not accurately reflect actual results under certain changes in interest rates.
In addition to interest rate risk, beginning in 2020, the COVID-19 pandemic exposed us and will likely continue to expose us to additional market value risk. Protracted business closures, furloughs and lay-offs curtailed economic activity, and will likely continue to curtail economic activity and could result in lower fair values for collateral in our commercial and 1-4 family portfolio segments.

The ALCO monitors various liquidity ratios to ensure a satisfactory liquidity position for us.  Management continually evaluates the condition of the economy, the pattern of market interest rates and other economic data to determine the types of investments that should be made and at what maturities.  Using this analysis, management from time to time assumes calculated interest sensitivity gap positions to maximize net interest income based upon anticipated movements in the general level of interest rates.  Regulatory authorities also monitor our gap position along with other liquidity ratios.  In addition, as described above, we utilize a simulation model to determine the impact of net interest income under several different interest rate scenarios.  By utilizing this model, we can determine changes that need to be made to the asset and liability mixes to mitigate the change in net interest income under these various interest rate scenarios.
