SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations CBTX, Inc., or the Company or CBTX, operates 35 branches, 19 in the Houston market area, 15 in the Beaumont/East Texas market area and one in Dallas, through its wholly-owned subsidiary, CommunityBank of Texas, N.A., or the Bank. The Bank provides relationship-driven commercial banking products and services primarily to small and mid-sized businesses and professionals with operations within the Bank’s markets. Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and the Bank. All material intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP, but do not include all the information and footnotes required for complete consolidated financial statements. In management’s opinion, these interim unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature necessary for a fair statement of the Company’s consolidated financial position at March 31, 2021 and December 31, 2020, consolidated results of operations, consolidated cash flow and consolidated shareholders’ equity for the three months ended March 31, 2021 and 2020. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year end and the results for the interim periods shown in this report are not necessarily indicative of results to be expected for the full year due in part to global economic and financial market conditions, interest rates, access to sources of liquidity, market competition and interruptions of business processes. These interim unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2020 included within the Company’s Annual Report on Form 10-K. Reclassification Share Repurchase Program Accounting Standards Recently Adopted If reference rates are discontinued, the existing contracts will be modified to replace the discontinued rate with a replacement rate. For accounting purposes, such contract modifications would have to be evaluated to determine whether the modified contract is a new contract or a continuation of an existing contract. If they are considered new contracts, the previous contract would be extinguished resulting in the acceleration of previously deferred fees and costs. Under one of the optional expedients of ASU 2020-04, modifications of contracts within the scope of Topic 310, Receivables, and 470, Debt, will be accounted for by prospectively adjusting the effective interest rates and no such evaluation is required. When elected, the optional expedient for contract modifications must be applied consistently for all eligible contracts or eligible transactions. The expedients and exceptions in this update are available to all entities starting March 12, 2020 through December 31, 2022. The Company began modifying LIBOR based loans during 2020 and applied the expedients and exceptions. Cash Flow Reporting As of March 31, 2021 and December 31, 2020, the Company had $4.5 million and $8.4 million, respectively, in cash held as collateral on deposit with other financial institution counterparties related to interest rate swap transactions. Reserves maintained with the Federal Reserve Bank and cash held as collateral for interest rate swap transactions are considered restricted cash.

No securities were sold in the three months ended March 31, 2021 and 2020. At March 31, 2021 and December 31, 2020, securities with a carrying amount of $28.8 million and $27.3 million, respectively, were pledged to secure public deposits and for other purposes required or permitted by law. There are multiple qualitative factors the Company considers to determine if an allowance for credit losses, or ACL, is necessary for those securities where the amortized cost basis exceeds the fair value. These factors include, among other things: (i) the extent to which the fair value was less than the amortized cost basis of the security and the length of time; (ii) the structure of the payments and likelihood that the issuer has the ability to make future payments; (iii) adverse conditions related to the security, industry or geographic area; (iv) changes in any credit ratings or financial conditions of the issuer; (v) failure by the issuer to make previous payments; and (vi) past events related to the security, current economic conditions and reasonable and supportable forecasts. Management did not believe that any of the securities the Company held at March 31, 2021 or December 31, 2020 were impaired due to reasons of credit quality and believed any unrealized losses were temporary. No ACL for available for sale securities was recorded in the Company’s condensed consolidated balance sheets at March 31, 2021 or during 2020. Amortized costs, as defined by GAAP, include acquisition costs, applicable accrued interest and accretion or amortization of premiums and discounts. The Company made a policy election to exclude accrued interest from amortized costs in the determination of ACL. The Company continues its policy of reversing previously accrued interest when it has been deemed uncollectible. Accrued interest receivable for securities was $797,000 and $1.2 million at March 31, 2021 and December 31, 2020, respectively, and is included in other assets in the condensed consolidated balance sheets.

ALLOWANCE FOR CREDIT LOSSES	3 Months Ended
ALLOWANCE FOR CREDIT LOSSES	Mar. 31, 2021
ALLOWANCE FOR CREDIT LOSSES
ALLOWANCE FOR CREDIT LOSSES	NOTE 6: ALLOWANCE FOR CREDIT LOSSES The Company primarily manages credit quality and credit risk associated with its loan portfolio based on the risk grading assigned to each individual loan within the loan class. Each loan class is a grouping of loan receivables within the portfolio based on risk characteristics and the method for monitoring and assessing the associated credit risks. The Company’s ACL for the loan portfolio has two main components: (i) a reserve based on expected losses on loans with similar risk characteristics, or general reserve; and (ii) an ACL for individually evaluated loans that do not share similar risk characteristics with other loans, or specific reserve. To determine the specific ACL, the Company utilizes various methods including discounted cash flow analysis and appraisal valuation on collateral to determine any expected credit losses requiring an ACL. To estimate the general ACL, the Company utilizes an age-based vintage model, or the Vintage Model, where it has divided the loan portfolio into portfolio segments of loans with similar risk characteristics and further subdivided the portfolio segments by the age of the loan or vintage. The vintage of a loan is determined based on the credit decision date, which is defined as the more recent of the origination date or the last renewal date. The factors considered to determine portfolio segments include: (i) loan class or major category of loans based on call codes; (ii) vintage; (iii) interest rate; (iv) loan size; (v) payment structure or term; (vi) risk ratings; (vii) loan to value; (viii) collateral type; (ix) geographical pattern; and (x) industrial sector. The Company has limited specific historical loss experience to directly tie to an attribute and thus the use of one factor over another is based on management’s perceived risk of the identified factor in combination with the data analyzed. The Company believes that this segmentation best represents the portfolio segments at a level to develop the systematic methodology in the determination of the ACL. Historical loss rates are adjusted for internal and external qualitative risk factors to determine a total expected loss rate for each vintage within each portfolio segment. The various internal The Company excludes accrued interest and deferred fees and costs in the determination of an ACL and reverses previously accrued interest when it has been deemed uncollectible. Loans held for sale are excluded from the computation of expected credit losses as they are carried at the lower of cost or market value. At March 31, 2021 and December 31, 2020, the ratio of the ACL for loans to loans excluding loans held for sale was 1.41% and 1.39%, respectively. The ACL continues to reflect the impact of the COVID-19 pandemic and the sustained instability in the oil and gas industry on the local and national economy and on current and forecasted expected credit losses. At March 31, 2021, there were minimal adjustments to the qualitative factors utilized in calculating the ACL. The increase in the ACL from December 31, 2020 to March 31, 2021 The review of the appropriateness of the ACL, which includes evaluation of historical loss trends, qualitative adjustments and forecasted economic conditions applied to general reserves, is performed by executive management and presented to the Board of Directors for its review on a quarterly basis. The ACL at March 31, 2021, reflects the Company’s assessment based on the information available at that time. Risk Grading The credit quality of the loan portfolio is assessed through different processes. At origination, a risk grade is assigned to each loan based on underwriting procedures and criteria. The risk grades used are described below. The Company monitors the credit quality of the loan portfolio on an on-going basis by performing loan reviews, both internally and through a third-party vendor, on loans meeting certain risk and exposure criteria. Any risk grade changes determined based on these loan reviews, including those related to criticized and classified loans, and any changes to specific reserves related to individually evaluated loans are approved by executive management.

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	Mar. 31, 2021
FAIR VALUE DISCLOSURES
FAIR VALUE DISCLOSURES	NOTE 13: FAIR VALUE DISCLOSURES The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction occurring 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. In estimating fair value, the Company uses valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques refer to the assumptions used in pricing the asset or liability. Valuation inputs are categorized in a three-level hierarchy, that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1 Inputs Level 2 Inputs Level 3 Inputs During the three months ended March 31, 2021 and the year ended December 31, 2020, there were no transfers of assets or liabilities within the levels of the fair value hierarchy. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon models that primarily use observable market-based parameters as inputs. Valuation adjustments may be made to ensure that assets and liabilities are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value could result in different estimates of fair value. Fair value estimates are based on judgments regarding current economic conditions, risk characteristics of the various instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Financial Instruments Measured at Fair Value on a Recurring Basis The Company’s assets and liabilities measured at fair value on a recurring basis include the following: Debt Securities Available for Sale Equity Securities Available for Sale Interest Rate Swaps Financial assets and financial liabilities measured at fair value on a recurring basis as of the dates shown below were as follows: March 31, December 31, (Dollars in thousands) 2021 2020 Fair value of financial assets: Level 1 inputs: Equity securities $ 1,176 $ 1,193 Debt securities available for sale - U.S. Treasury securities 11,821 — Level 2 inputs: Debt securities available for sale: State and municipal securities 106,185 93,037 U.S. agency securities: Callable debentures 2,951 — Collateralized mortgage obligations 33,994 35,402 Mortgage-backed securities 132,964 107,649 Interest rate swaps 5,902 8,618 Level 3 inputs: Credit risk participation agreement 11 40 Total fair value of financial assets $ 295,004 $ 245,939 Fair value of financial liabilities: Level 2 inputs: Interest rate swaps $ 5,902 $ 8,618 Total fair value of financial liabilities $ 5,902 $ 8,618 Financial Instruments Measured at Fair Value on a Non-recurring Basis A portion of financial instruments are measured at fair value on a non-recurring basis and are subject to fair value adjustments in certain circumstances. Financial assets measured at fair value on a non-recurring basis during the dates shown below include certain loans reported at the fair value of the underlying collateral if repayment is expected solely from the collateral or a discounted cash flow method if not. Prior to foreclosure, estimated fair values for collateral is estimated based on Level 3 inputs based on customized discounting criteria. The Company’s financial assets measured at fair value on a non-recurring basis are certain individually evaluated loans and as of the dates shown below were as follows: March 31, 2021 December 31, 2020 (Dollars in thousands) Recorded Investment Specific ACL Net Recorded Investment Specific ACL Net Level 3 inputs: Loans evaluated individually Commercial and industrial $ 10,373 $ 5,476 $ 4,897 $ 10,509 $ 5,004 $ 5,505 Commercial real estate 5,727 274 5,453 5,727 323 5,404 Consumer 90 6 84 — — — Other — — — 1,232 205 1,027 Total $ 16,190 $ 5,756 $ 10,434 $ 17,468 $ 5,532 $ 11,936 Non-Financial Assets and Non-Financial Liabilities Measured at Fair Value on a Non-recurring Basis The Company’s non-financial assets measured at fair value on a non-recurring basis for the periods reported are foreclosed assets (upon initial recognition or subsequent impairment). The Company’s other non-financial assets whose fair value may be measured on a non-recurring basis when there is evidence of impairment and may be subject to impairment adjustments include goodwill and intangible assets, among other assets. The fair value of foreclosed assets may be estimated using Level 2 inputs based on observable market data or Level 3 inputs based on customized discounting criteria less estimated selling costs. There were no write-downs of foreclosed assets for fair value remeasurement subsequent to initial foreclosure during the three months ended March 31, 2021 or during 2020.

DERIVATIVE FINANCIAL INSTRUMENTS
DERIVATIVE FINANCIAL INSTRUMENTS	NOTE 14: DERIVATIVE FINANCIAL INSTRUMENTS The Company has outstanding interest rate swap contracts with certain customers and equal and offsetting interest rate swaps with other financial institutions entered into at the same time. These interest rate swap contracts are not designated as hedging instruments for mitigating interest rate risk. The objective of the transactions is to allow customers to effectively convert a variable rate loan to a fixed rate. In connection with each swap transaction, the Company agreed to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, the Company agreed 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. Because the Company acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts are designed to offset each other and do not significantly impact the Company’s operating results except in certain situations where there is a significant deterioration in the customer’s credit worthiness or that of the counterparties. At March 31, 2021 and December 31, 2020, management determined there was no such deterioration. At March 31, 2021 and December 31, 2020, the Company had 23 and 23 interest rate swap agreements outstanding with borrowers and financial institutions, respectively. These derivative instruments are not designated as accounting hedges and changes in the net fair value are recognized in other noninterest income. Fair value amounts are included in other assets and other liabilities. The Company has a credit risk participation agreement with another financial institution that is associated with an interest rate swap related to a loan for which the Company is the lead agent bank and the other financial institution provides credit protection to the Company should the borrower fail to perform under the terms of the interest rate swap agreement. The fair value of the agreement is determined based on the market value of the underlying interest rate swap adjusted for credit spreads and recovery rates. Derivative instruments outstanding as of the dates shown below were as follows: Weighted Average Notional Fair Maturity (Dollars in thousands) Classification Amounts Value Fixed Rate Floating Rate (Years) March 31, 2021 Interest rate swaps with customers Other assets $ 102,973 $ 4,568 3.25% - 5.89% LIBOR 1M + 2.50% - 3.00% 4.77 Interest rate swaps with financial institutions Other assets 37,210 1,105 3.50% LIBOR 1M + 2.50% 8.99 Interest rate swaps with customers Other assets 5,223 229 4.99% U.S. Prime 6.71 Interest rate swaps with financial institutions Other liabilities 5,223 (229) 4.99% U.S. Prime 6.71 Interest rate swaps with financial institutions Other liabilities 102,973 (4,568) 3.25% - 5.89% LIBOR 1M + 2.50% - 3.00% 4.77 Interest rate swaps with customers Other liabilities 37,210 (1,105) 3.50% LIBOR 1M + 2.50% 8.99 Credit risk participation agreement with financial institution Other assets 13,954 11 3.50% LIBOR 1M + 2.50% 8.99 Total derivatives $ 304,766 $ 11 December 31, 2020 Interest rate swaps with customers Other assets $ 141,241 $ 8,146 3.25% - 5.89% LIBOR 1M + 2.50% - 3.00% 6.14 Interest rate swaps with customers Other assets 5,250 472 4.99% U.S. Prime 6.96 Interest rate swaps with financial institutions Other liabilities 5,250 (472) 4.99% U.S. Prime 6.96 Interest rate swaps with financial institutions Other liabilities 141,241 (8,146) 3.25% - 5.89% LIBOR 1M + 2.50% - 3.00% 6.14 Credit risk participation agreement with financial institution Other assets 14,084 40 3.50% LIBOR 1M + 2.50% 9.24 Total derivatives $ 307,066 $ 40

COMMITMENTS AND CONTINGENCIES AND FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK	NOTE 16: COMMITMENTS AND CONTINGENCIES AND FINANCIAL INSTRUMENTS WITH OFF - - Financial Instruments with Off-Balance-Sheet Risk The Company enters into commitments to extend credit and standby letters of credit to meet customer financing needs and, in accordance with GAAP, these commitments are not reflected as liabilities in the consolidated balance sheets. Due to the nature of these commitments, the amounts disclosed in the tables below do not necessarily represent future cash requirements. Commitments to extend credit and standby letters of credit as of the dates shown below were as follows: March 31, December 31, (Dollars in thousands) 2021 2020 Commitments to extend credit, variable interest rate $ 656,809 $ 659,385 Commitments to extend credit, fixed interest rate 67,233 80,346 Total commitments $ 724,042 $ 739,731 Standby letters of credit $ 27,200 $ 26,078 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract, generally have fixed expiration dates or other termination clauses and may expire without being fully drawn upon. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third-party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to the Company’s customers. Litigation The Company is subject to claims and lawsuits which arise primarily in the ordinary course of business. Based on information presently available and advice received from legal counsel representing the Company, it is the opinion of management that the disposition or ultimate determination of such claims and lawsuits will not have a material adverse effect on the financial position or results of operations of the Company.

STOCK-BASED COMPENSATION
STOCK-BASED COMPENSATION	NOTE 18: STOCK-BASED COMPENSATION The Company acquired a stock option plan which originated under VB Texas, Inc. as a part of a merger of the two companies, or the 2006 Plan. At the merger date, all outstanding options under this plan became fully vested and exercisable. The plan expired in 2016 and no additional options may be granted under its terms. As of March 31, 2021, there were options outstanding to acquire 45,720 shares of the Company’s common stock under the 2006 Plan, all of which will expire in 2022 if not exercised. In 2014, the Company adopted the 2014 Stock Option Plan, or the 2014 Plan, which was approved by the Company’s shareholders and limits the number of shares that may be optioned to 1,127,200. The 2014 Plan provides that no options may be granted after May 20, 2024. Options granted under the 2014 Plan expire 10 years from the date of grant and become exercisable in installments over a period of one In 2017, the Company adopted the 2017 Omnibus Incentive Plan, or the 2017 Plan. The 2017 Plan authorizes the Company to grant options, performance-based and non-performance based restricted stock awards as well as various other types of stock-based awards and other awards that are not stock-based to eligible employees, consultants and non-employee directors up to an aggregate of 600,000 shares of common stock. As of March 31, 2021, 278,214 shares were available for future grant under the 2017 Plan.

Restricted stock shares are considered fully issued at the time of the grant and the grantee becomes the record owner of the restricted stock and has voting, dividend and other shareholder rights. The shares of restricted stock are non-transferable and subject to forfeiture until the restricted stock vests and any dividends with respect to the restricted stock are subject to the same restrictions, including the risk of forfeiture. Non-performance based restricted stock grants vest over the service period in equal increments over a period of two The number of shares earned under the Company’s performance-based restricted stock award agreements is based on the achievement of certain branch production goals. Compensation expense for performance-based restricted stock is recognized for the probable award level over the period estimated to achieve the performance conditions and other goals, on a straight-line basis. If the probable award level and/or the period estimated to be achieved change, compensation expense will be adjusted via a cumulative catch-up adjustment to reflect these changes. The performance conditions and goals must be achieved within five years or the awards expire. The number of performance-based shares granted presented in the table below is based upon the attainment of the maximum number of shares possible to be earned. Restricted stock activity for the periods shown below was as follows: Non-performance Based Performance-based Weighted Weighted Average Average Number of Grant Date Number of Grant Date Shares Fair Value Shares Fair Value Outstanding at December 31, 2019 161,443 $ 28.20 18,000 $ 34.46 Granted 37,107 29.55 — — Vested (6,450) 32.11 — — Forfeited (204) 30.64 — — Outstanding at March 31, 2020 191,896 $ 28.33 18,000 $ 34.46 Outstanding at December 31, 2020 129,667 28.22 2,250 34.40 Granted 33,285 26.32 — — Vested (13,369) 30.72 — — Forfeited — — — — Outstanding at March 31, 2021 149,583 $ 27.58 2,250 $ 34.40 A summary of restricted stock as of the date shown below was as follows: March 31, 2021 Restricted Stock Non-performance Based Performance-based Number of shares underlying restricted stock 149,583 2,250 Weighted-average grant date fair value per share $ 27.58 $ 34.40 Aggregate fair value (in thousands) $ 4,595 $ 69 Weighted-average remaining vesting period (years) 1.8 2.5 The Company’s stock compensation plans allow employees to elect to have shares withheld to satisfy their tax liabilities related to options exercised or restricted stock vested or to pay the exercise price of the options.

REGULATORY MATTERS

REGULATORY MATTERS	3 Months Ended
REGULATORY MATTERS	Mar. 31, 2021
REGULATORY MATTERS
REGULATORY MATTERS	NOTE 19: REGULATORY MATTERS Banks and bank holding companies are subject to various regulatory capital requirements administered by state and federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting and other factors. The Company and the Bank’s Common Equity Tier 1 capital includes common stock and related capital surplus, net of treasury stock, and retained earnings. In connection with the adoption of the Basel III Capital Rules, the Company and the Bank elected to opt-out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1 capital. Common Equity Tier 1 capital for both the Company and the Bank is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities. The Basel III Capital Rules require the Company and the Bank to maintain: (i) a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 4.5%, plus a 2.5% “capital conservation buffer” (which is added to the 4.5% Common Equity Tier 1 capital ratio, effectively resulting in a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 7.0%); (ii) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the capital conservation buffer (which is added to the 6.0% Tier 1 capital ratio, effectively resulting in a minimum Tier 1 capital ratio of 8.5%); (iii) a minimum ratio of total capital (that is, Tier 1 plus Tier 2) to risk-weighted assets of at least 8.0%, plus the capital conservation buffer (which is added to the 8.0% total capital ratio, effectively resulting in a minimum total capital ratio of 10.5%); and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average quarterly assets. The Basel III Capital Rules also provide for a “countercyclical capital buffer” that is applicable to only certain covered institutions and does not have any current applicability to the Company and the Bank. The capital conservation buffer is designed to absorb losses during periods of economic stress and, as detailed above, effectively increases the minimum required risk-weighted capital ratios. Banking institutions with a ratio of Common Equity Tier 1 capital to risk-weighted assets below the effective minimum (4.5% plus the capital conservation buffer and, if applicable, the countercyclical capital buffer) will face constraints on dividends, equity repurchases, and compensation based on the amount of the shortfall. In November 2019, the federal bank regulatory agencies published a final rule, the Community Bank Leverage Ratio Framework, or the Framework, to simplify capital calculations for community banks. The Framework provides for a simple measure of capital adequacy for certain community banking organizations. The Framework is optional and is designed to reduce burden by removing requirements for calculating and reporting risk-based capital ratios. Depository institutions and depository institution holding companies that have less than $10.0 billion in total consolidated assets and meet other qualifying criteria, including a leverage ratio of greater than 9.0%, are considered qualifying community banking organizations and are eligible to opt into the Framework. A qualifying community banking organization that elects to use the community bank leverage ratio framework and that maintains a Tier 1 capital-to-adjusted total assets ratio, or leverage capital ratio, of greater than 9.0% is considered to have satisfied the generally applicable risk-based and leverage capital requirements under the Basel III Capital Rules and, if applicable, is considered to have met the “well capitalized” ratio requirements for purposes of its primary federal regulator’s prompt corrective action rules. The final rule became effective January 1, 2020, and organizations that opt into the Framework and meet the criteria established by the rule can use the Framework for regulatory reports for the year ended December 31, 2020. In April 2020, the federal bank regulatory agencies announced two interim final rules to provide relief associated with Section 4012 of the Coronavirus Aid Relief and Economic Security Act, or CARES Act. For institutions that elect the Framework, the interim rules temporarily lowered the leverage ratio requirement to 8.0% for the second quarter of 2020 through the end of calendar year 2020 and to 8.5% for the 2021 calendar year. An institution will have until January 1, 2022 before the 9.0% leverage ratio requirement is re-established. The Company determined not to opt into the Framework and will continue to compute regulatory capital ratios based on the Basel III Capital Rules discussed above. In September 2020, the federal bank regulatory agencies finalized an interim final rule that allows banking organizations to mitigate the effects of CECL on their regulatory capital computations. The rule permits banking organizations that were required to adopt CECL for purposes of GAAP (as in effect January 1, 2020) for a fiscal year beginning during the calendar year 2020, the option to delay for up to two years an estimate of CECL’s effect on regulatory capital, followed by a three-year transition period (i.e., a transition period of five years in total). The Company determined not to use the transition provision and has reported the full effect of CECL upon adoption and for each reporting period thereafter in its regulatory capital calculation and ratios. The Company is subject to the regulatory capital requirements administered by the Board of Governors of the Federal Reserve System and, for the Bank, those administered by the Office of Comptroller of Currency, or OCC. Regulatory authorities can initiate certain mandatory actions if the Company or the Bank fail to meet the minimum capital requirements, which could have a direct material effect on the Company’s financial statements. Management believes, as of March 31, 2021 and December 31, 2020, that the Company and the Bank met all capital adequacy requirements to which they were subject. financing, and suspicious activity; and (vii) performing a review of account and transaction activity for certain time periods. The Board of Directors and management are committed to taking the necessary actions to fully address the provisions of the Agreement. The Bank has appointed a Compliance Committee to oversee the Bank’s compliance with the Agreement and is working to promptly address the requirements of the Agreement. Numerous actions have already been taken or commenced by the Bank to strengthen its BSA/AML compliance practices, policies, procedures and controls and comply with the terms of the Agreement. The Bank has hired and may continue to hire third-party consultants and advisors to assist in complying with the Agreement. While subject to the Agreement, the Company expects that management and the Board of Directors will be required to focus considerable time and attention on taking corrective actions to comply with its terms. If the Bank does not successfully address the OCC’s concerns in the Agreement or fully comply with the provisions of the Agreement, the Bank could be subject to further regulatory scrutiny, civil monetary penalties, further regulatory sanctions and/or other enforcement actions. The Company or the Bank may also become subject to formal or informal enforcement actions by other regulatory agencies. Any of those events could have a material adverse impact on the Company’s future operations, financial condition, growth, or other aspects. At March 31, 2021 and December 31, 2020, the Company and the Bank, were “well capitalized” based on the ratios presented below.

Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels. Approval is also required if dividends declared exceed the net profits for that year combined with the retained net profits for the preceding two years.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and the Bank. All material intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP, but do not include all the information and footnotes required for complete consolidated financial statements. In management’s opinion, these interim unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature necessary for a fair statement of the Company’s consolidated financial position at March 31, 2021 and December 31, 2020, consolidated results of operations, consolidated cash flow and consolidated shareholders’ equity for the three months ended March 31, 2021 and 2020. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year end and the results for the interim periods shown in this report are not necessarily indicative of results to be expected for the full year due in part to global economic and financial market conditions, interest rates, access to sources of liquidity, market competition and interruptions of business processes. These interim unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2020 included within the Company’s Annual Report on Form 10-K.

Accounting Standards Recently Adopted	If reference rates are discontinued, the existing contracts will be modified to replace the discontinued rate with a replacement rate. For accounting purposes, such contract modifications would have to be evaluated to determine whether the modified contract is a new contract or a continuation of an existing contract. If they are considered new contracts, the previous contract would be extinguished resulting in the acceleration of previously deferred fees and costs. Under one of the optional expedients of ASU 2020-04, modifications of contracts within the scope of Topic 310, Receivables, and 470, Debt, will be accounted for by prospectively adjusting the effective interest rates and no such evaluation is required. When elected, the optional expedient for contract modifications must be applied consistently for all eligible contracts or eligible transactions. The expedients and exceptions in this update are available to all entities starting March 12, 2020 through December 31, 2022. The Company began modifying LIBOR based loans during 2020 and applied the expedients and exceptions.
