Cautionary Note Regarding Forward-Looking Statements
This Report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. In particular, information appearing under “Business,” “Risk Factors,” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” includes forward-looking statements. Forward-looking statements are neither statements of historical fact nor assurance of future performance and generally can be identified by the use of forward-looking terminology such as “believes”, “expects”, “may”, “will”, “could”, “should”, “projects”, “plans”, “goal”, “targets”, “potential”, “estimates”, “pro forma”, “seeks”, “intends”, or “anticipates”, or similar expressions. Forward-looking statements include discussions of strategy, financial projections, guidance and estimates (including their underlying assumptions), statements regarding plans, objectives, expectations or consequences of various transactions or events, and statements about our future performance, operations, products and services, and should be viewed with caution.
Because forward-looking statements relate to the future, they are subject to known and unknown risks, uncertainties, assumptions and changes in circumstances, many of which are out of our control, and that are difficult to predict as to timing, extent, likelihood and degree of occurrence, and that could cause actual results to differ materially from the results implied or anticipated by the statements. Except as required by law, we expressly disclaim any obligations to publicly update any forward-looking statements whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements, in addition to those described in detail under Items 1A of this Report - “Risk Factors” - include, but are not limited to the following:
negative economic and political conditions that adversely affect the general economy, housing prices, the real estate market, the job market, consumer confidence, the financial condition of our borrowers and consumer spending habits, which may affect, among other things, the levels of non-performing assets, charge-offs and provision expense;
changes in loan underwriting, credit review or loss policies associated with economic conditions, examination conclusions or regulatory developments, either as they currently exist or as they may be affected by conditions associated with the COVID-19 pandemic;
the COVID-19 pandemic and its continuing effects on the economic and business environments in which we operate;
strategic, market, operational, liquidity and interest rate risks associated with our business;
continuation of historically low interest rates coupled with other potential fluctuations or unanticipated changes in the interest rate environment, including interest rate changes made by the Federal Reserve, the discontinuation of LIBOR as an interest rate benchmark, as well as cash flow reassessments may reduce net interest margin and/or the volumes and values of loans made or held as well as the value of other financial assets;
our lack of geographic diversification and any unanticipated or greater than anticipated adverse conditions in the national or local economies in which we operate;
our loan concentration in industries or sectors that may experience unanticipated or greater than anticipated adverse conditions than other industries or sectors in the national or local economies in which we operate;
the risks of expansion into new geographic or product markets;
risks with respect to future mergers or acquisitions, including our ability to successfully expand and complete acquisitions and integrate businesses and operations that we acquire;
our ability to attract and retain key employees;
competition from financial institutions and other financial service providers including non-bank financial technology providers and our ability to attract customers from other financial institutions;
losses due to fraudulent and negligent conduct of our customers, third party service providers or employees;
cybersecurity risks and the vulnerability of our network and online banking portals, and the systems or parties with whom we contract, to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss and other security breaches that could adversely affect our business and financial performance or reputation;
our reliance on third parties to provide key components of our business infrastructure and services required to operate our business;
the risk that we may be required to make substantial expenditures to keep pace with regulatory initiatives and the rapid technological changes in the financial services market;
the availability of and access to capital;
legislative, regulatory or accounting changes that may adversely affect us;
volatility in the ACL resulting from the CECL methodology, either alone or as that may be affected by conditions arising out of the COVID-19 pandemic;
adverse results (including judgments, costs, fines, reputational harm, inability to obtain necessary approvals and/or other negative effects) from current or future litigation, regulatory proceedings, examinations, investigations, or similar matters, or developments related thereto;
any matter that would cause us to conclude that there was impairment of any asset, including intangible assets, such as goodwill;
5


limitations on our ability to declare and pay dividends and other distributions from the Bank to the Holding Company, which could affect Holding Company liquidity, including its ability to pay dividends to shareholders or take other capital actions; and
other risks and uncertainties disclosed in documents filed or furnished by us with or to the SEC, any of which could cause actual results to differ materially from future results expressed, implied or otherwise anticipated by such forward-looking statements.

PART I
Unless the context otherwise requires, the terms “we,” “our,” or “us” refer to United Community Banks, Inc. and its direct and indirect subsidiaries, including United Community Bank.

ITEM 1.    BUSINESS.

Overview

We are a bank holding company with approximately $17.8 billion in assets as of December 31, 2020. We were incorporated in 1987 and began operations in 1988 in the state of Georgia by acquiring the capital stock of the Bank, a Georgia state-chartered bank that opened in 1950. We have since grown through a combination of acquisitions and strategic growth throughout the Georgia, South Carolina, North Carolina, Tennessee, and Florida markets, as well as nationally through our SBA/USDA lending and equipment finance businesses.

Recent Developments during 2020

COVID-19 Pandemic

During 2020, global financial markets experienced significant volatility resulting from the spread of a novel coronavirus known as COVID-19. In March of 2020, the World Health Organization declared COVID-19 a global pandemic and the United States declared a National Public Health Emergency. The COVID-19 pandemic has materially restricted and continues to materially restrict the level of economic activity in our markets. In response to the pandemic, state governments both inside and outside of our markets took and continue to take preventative or protective actions, such as imposing restrictions on travel and business operations, advising or requiring individuals to limit or forgo time outside of their homes, and ordering temporary closures of businesses that have been deemed to be non-essential. These measures have dramatically increased unemployment in the United States and have negatively impacted many businesses, and thereby threatened the repayment ability of some of our borrowers.

To address the economic impact in the United States, the CARES Act was enacted in March 2020. The CARES Act included a number of provisions that affected us, including accounting relief for TDRs and regulatory capital relief for the effect of CECL implementation. The CARES Act also established the PPP through the SBA, which allowed us to lend money to small businesses, with guarantees from the SBA, to maintain employee payrolls and pay other qualified expenses during the crisis. Under this program, loan amounts may be forgiven if the proceeds were used for payroll and other permitted expenses in accordance with the requirements of the PPP, and the borrower meets certain other requirements.

The Federal Reserve also took additional steps to bolster the economy by, among other things, reducing the federal funds rate and the discount-window borrowing rate to near zero.

In response to the pandemic, we implemented protocols and processes to help protect our employees, customers and communities. These measures included:

Temporarily operating our branches under a drive-through model with appointment-only lobby service, facilitating work from home, when possible, for employees, and leveraging our business continuity plans that include critical operations teams being divided and dispersed to separate locations;

Offering assistance to our customers affected by the COVID-19 pandemic, including payment deferrals, waiving certain fees, suspending property foreclosures, and participating in the CARES Act and lending programs for businesses, including the SBA PPP;

Temporarily suspending common stock repurchases to maximize capital and liquidity resources; and

Issuing $100 million of non-cumulative perpetual preferred stock and $100 million of senior debentures to ensure our capital ratios and liquidity remain strong throughout the rapidly changing economic conditions.

In connection with reviewing our financial condition in light of the pandemic, we evaluated certain assets, including goodwill and other intangibles, for potential impairment. Based upon our most recent review as of December 31, 2020, we determined that no impairments have occurred. We also elected to delay for two years the phase-in of the capital impact from our adoption of ASC 326, the new accounting standard on credit losses. For more information, see Capital Adequacy.

As indicated, we implemented various consumer and commercial loan modification programs to provide our borrowers relief from the economic impacts of COVID-19. Based on guidance in the CARES Act, COVID-19 related modifications to loans that were current as
7


of December 31, 2019 are exempt from TDR classification under GAAP. In addition, the bank regulatory agencies issued interagency guidance stating that COVID-19 related short-term modifications (i.e., payment deferrals) granted to loans that were current as of the loan modification program implementation date are not new TDRs. For more information, see Table 16 - COVID-19 Deferrals in Part II, Item 7. MD&A of this Report.

Acquisition of Three Shores Bancorporation, Inc.

On July 1, 2020, we acquired Three Shores, including its wholly-owned subsidiary, Seaside, headquartered in Orlando, Florida. Seaside operated a 14-branch network located in key Florida metropolitan markets. In this acquisition, United acquired $2.13 billion of assets and assumed $1.99 billion of liabilities. In the merger, Three Shores shareholders received $188 million in total consideration, consisting of $164 million (8.13 million shares) in United common stock and $24.1 million in cash.

Operations

We provide a wide array of commercial and consumer banking services, including checking, savings and time deposit accounts, secured and unsecured loans, mortgage loans, payment services, wire transfers, wealth management, trust services, private banking, investment advisory services, insurance, and other related financial services to our customers. Our business model combines the commitment to exceptional customer service of a local bank with the products and expertise of a larger institution. We believe that we have a strong culture focused on the golden rule of banking – treating each other and the customer the way we would want to be treated. We exist to serve our customers, and we are committed to making lives better through outstanding products, dedication to our customers, and serving the communities in which we operate.

We operate as a locally-focused community bank, supplemented by experienced, centralized support to deliver products and services to our larger, more sophisticated, customers. Our organizational structure reflects these strengths, with local leaders for each market and market advisory boards operating in partnership with the product experts of our Commercial Banking Solutions unit. We believe that this combination of service and expertise sets us apart and is instrumental in our strategy to build long-term relationships.

Our revenue is primarily derived from interest on and fees received in connection with the loans we make and from interest and dividends from our investment securities and short-term investments. The principal sources of funds for our lending activities are customer deposits, repayment of loans, and the sale and maturity of investment securities. Our principal expenses are interest paid on deposits and other borrowings and operating and general administrative expenses.
Lending Activities

We offer a full range of lending services, including real estate, consumer and commercial loans, to individuals, small businesses, mid-sized commercial businesses and non-profit organizations. We also originate loans partially guaranteed by the SBA and to a lesser extent by the USDA loan programs. Our consolidated loans at December 31, 2020 were $11.4 billion, or 64% of total consolidated assets. The interest rates that we charge on loans vary with the degree of risk, maturity and amount of the loan, and are further subject to competitive pressures, deposit costs, availability of funds and government regulations.

The most significant categories of our loans are those to finance owner occupied real estate, commercial income property, commercial and industrial equipment and operating loans, and consumer loans secured by personal residences. A majority of our loans are made on a secured basis.

The majority of our loans are to customers located in the immediate market areas of our banking locations in Georgia, South Carolina, North Carolina, Tennessee, and Florida, including customers who have a seasonal residence in our market areas. We originate a significant portion of our SBA/USDA and equipment finance loans on a national basis, to customers outside of our immediate market areas.

Our full-service retail mortgage lending division, UCMS, is approved as a seller/servicer for the Fannie Mae and the Freddie Mac and provides fixed and adjustable-rate home mortgages. During 2020, the Bank originated $2.12 billion in residential mortgage loans for the purchase of homes and to refinance existing mortgage debt. The majority of these mortgages were sold into the secondary market without recourse to us, other than for breaches of warranties. We have retained the servicing on most of our mortgage loans sold.
Our credit organization provides each lending officer with written guidelines for lending activities, and limited lending authority is delegated to lending officers. Loans in excess of individual officer credit authority must be approved by a senior officer with sufficient approval authority delegated by our credit organization or by our Senior Credit Committee.
8


Our Regional Credit Officers, Senior Credit Officers, and Senior Risk Officers provide credit approval and portfolio administration support for our commercial lending operations as needed. Our Regional Credit Officers have lending authority set by our Chief Commercial Credit Officer based on characteristics of the markets they serve. For commercial loan relationships less than $500,000, we use a centralized small business lending/underwriting department.
We have a centralized consumer credit center that provides underwriting, regulatory disclosure and document preparation for all consumer loan requests originated by our lenders. Applications are processed through an automated loan origination software platform and approved by credit center underwriters.
Our Loan Review Department reviews, or engages an independent third party to review, our loan portfolio on an ongoing basis to identify any weaknesses in the portfolio and to assess the general quality of credit underwriting. The results of such reviews are presented to our executive management and our Board.
For additional information regarding our lending activity, see the section captioned “Loans” in the “Balance Sheet Review” section of Part II, Item 7. MD&A of this Report.
Deposit Activities
Deposits are the major source of our funds for lending and other investment activities. We offer our customers a variety of deposit products, including checking accounts, savings accounts, money market accounts and other deposit accounts, through multiple channels, including our network of full-service branches and our online, mobile and telephone banking platforms. We consider the majority of our regular savings, demand, NOW and money market deposit accounts to be core deposits. Generally, we attempt to maintain the rates paid on our deposits at a competitive level. We generate the majority of our deposits from customers in our local markets. For additional information regarding our deposit accounts, see the section captioned “Deposits” in Part II, Item 7. MD&A of this Report.
Investments
We use our investment portfolio to provide for the investment of excess funds at acceptable risk levels while providing liquidity to fund loan demand or to offset fluctuations in deposits. Our portfolio consists primarily of residential and commercial mortgage-backed securities, asset-backed securities, U.S. Treasury, U.S. agency and municipal obligations. Most of the securities are classified by us as available-for-sale and recorded on our balance sheet at fair value at each balance sheet date. Changes in fair value on available-for-sale securities are generally recorded directly in our shareholders’ equity account and are not recognized in our income statement.
Wealth Management, Trust, and Insurance
Through our Seaside Wealth Management division, we provide financial planning services, customized portfolio management and investment advice utilizing an open architecture approach to the selection of asset managers. We also offer trust services to manage fiduciary assets. Seaside Capital Management, Inc., a registered investment advisor that is a subsidiary of the Bank, offers investment advisory services for clients who wish to utilize an independent custodian. Seaside Insurance, Inc., a subsidiary of the Bank, operates as an independent insurance agency for our clients.
Through our United Community Advisory Services division, we generate fee revenue through the sale of non-deposit investment products and insurance products, including life insurance, long-term care insurance and tax-deferred annuities, to our customers. We have an affiliation with a third party broker/dealer, LPL Financial, to facilitate this line of business.
Reinsurance and Merchant Services
We own a captive insurance subsidiary, NLFC Reinsurance Corp., which provides reinsurance on a property insurance contract covering equipment financed by our equipment financing division.
We provide payment processing services for our commercial and small business customers through UCPS. UCPS is a joint venture between the Bank and BluePay Processing, LLC, a merchant services provider and subsidiary of Fiserv, Inc.
Competition
We compete in the highly competitive banking and financial services industry. Our profitability depends principally on our ability to effectively compete in the markets in which we conduct business.
We experience strong competition from both bank and non-bank competitors. Broadly speaking, we compete with national banks, super-regional banks, smaller community banks, credit unions, non-traditional internet-based banks and insurance companies. We also
9


compete with other financial intermediaries and investment alternatives such as mortgage companies, credit card issuers, leasing companies, finance companies, money market mutual funds, brokerage firms, governmental and corporate bond issuers, and other securities firms. Many of these non-bank competitors are not subject to the same regulatory oversight, which can provide them a competitive advantage in some instances. In many cases, our competitors have substantially greater resources and offer certain services that we are unable to provide to our customers.
We encounter strong pricing competition in providing our services, particularly in making loans and attracting deposits. The larger national and super-regional banks may have significantly greater lending limits and may offer additional products. We attempt to compete successfully with our competitors, regardless of their size, by emphasizing customer service while continuing to provide a wide variety of services.

We expect competition in the industry to continue to increase mainly as a result of the improvement in financial technology used by both existing and new banking and financial services firms. Competition may further intensify as additional companies (both banks and non-banks) enter the markets where we conduct business, competitors combine to present more formidable challengers, and we enter mature markets in accordance with our expansion strategy.

Acquisitions and Expansion
We look for opportunities to expand into attractive markets in which we believe our operating model will be successful. We have entered new markets and expanded our product offerings both by establishing new branches and service locations and also by selective acquisitions of existing market participants. We have developed a number of commercial lending businesses organically, which provide local commercial real estate, middle market, senior living, renewable energy, builder finance and asset-based lending services. We generally seek acquisition partners that share a similar culture and commitment to customer service. Acquisitions typically involve the payment of a premium over book and market values and, therefore, some dilution to our book value may occur with any future transactions. Our goal is to maintain a reasonable earn-back period of any tangible book value dilution, using realistic growth and expense reduction assumptions, as well as to achieve an attractive return on investment. Our ability to engage in any potential acquisition will depend upon the review and approval from various bank regulatory authorities.

Supervision and Regulation
 
General

Like all banks and bank holding companies, we are regulated extensively under state and federal banking laws. The regulatory framework is intended primarily for the protection of the depositors, the federal deposit insurance fund and the banking system as a whole and not for the protection of our shareholders and creditors. Certain provisions of laws and regulations affecting financial services firms are subject to further rulemaking, guidance and interpretation by the applicable federal regulators. The Holding Company is subject to the examination and reporting requirements of the Federal Reserve and the GADBF and also is subject to regulation by the SEC by virtue of its status as a public company and due to the nature of some of its businesses. The Bank is subject to examination and reporting requirements of the FDIC, the GADBF and the CFPB. The financial statements and information contained herein have not been reviewed, or confirmed for accuracy or relevance, by the FDIC or any other regulator.

The following is a general summary of the material aspects of certain statutes and regulations applicable to us. These summary descriptions are not complete, and you should refer to the full text of the statutes, regulations, and corresponding guidance for more information. These statutes and regulations are subject to change, and additional statutes, regulations, and corresponding guidance may be adopted. We are unable to predict these future changes or the effects, if any, that these changes could have on our business, revenues, and results of operations.

Bank Holding Company Regulation

The Holding Company is a registered bank holding company subject to regulation by the Federal Reserve under the BHC Act and is required to file annual and quarterly financial information with, and is subject to periodic examination by, the Federal Reserve. The BHC Act requires every bank holding company to obtain the Federal Reserve’s prior approval before (1) acquiring direct or indirect ownership or control of more than 5% of the voting shares of any bank that it does not already control; (2) acquiring all or substantially all of the assets of a bank; and (3) subject to certain exceptions, merging or consolidating with any other bank holding company. In addition, a bank holding company is generally prohibited from engaging in, or acquiring a direct or indirect interest in or control of more than 5% of the voting shares of any company engaged in, non-banking activities. This prohibition does not apply to activities listed in the BHC Act or found by the Federal Reserve, by order or regulation, to be closely related to banking or managing or controlling banks as to be a proper incident thereto. 
10



Some of the activities that the Federal Reserve has determined by regulation or order to be closely related to banking are: 
making or servicing loans and certain types of leases;
performing certain data processing services;
acting as fiduciary or investment or financial advisor;
providing brokerage services;
underwriting bank eligible securities;
underwriting debt and equity securities on a limited basis through separately capitalized subsidiaries; and
making investments in corporations or projects designed primarily to promote community welfare.

Although the activities of bank holding companies have traditionally been limited to the business of banking and activities closely related or incidental to banking (as discussed above), the GLB Act relaxed the previous limitations and permitted bank holding companies to engage in a broader range of financial activities. Specifically, bank holding companies may elect to become financial holding companies, which allows them to affiliate with securities firms and insurance companies and engage in other activities that are financial in nature. We have not sought financial holding company status, but we may elect that status in the future. If we were to become a financial holding company, we would be required to be well capitalized and well managed, and each insured depository institution we control would also have to be well capitalized, well managed and have at least a satisfactory rating under the CRA (discussed below).
 
The Holding Company also must register with the GADBF and file periodic information with the GADBF. As part of such registration, the GADBF requires information with respect to our financial condition, operations, management and intercompany relationship and related matters. The GADBF may also require such other information as is necessary to keep itself informed concerning compliance with Georgia law and the regulations and orders issued thereunder by the GADBF, and the GADBF may examine both the Holding Company and the Bank. Although the Bank operates branches in North Carolina, Tennessee, South Carolina and Florida, none of the North Carolina Banking Commission, the Tennessee Department of Financial Institutions, the South Carolina Commissioner of Banking, or the Florida Office of Financial Regulation examines or directly regulates out-of-state holding companies. 

The Holding Company is an “affiliate” of the Bank under the Federal Reserve Act, which imposes certain restrictions on (1) loans by the Bank to the Holding Company, (2) investments in the stock or securities of the Holding Company by the Bank, (3) the Bank taking the stock or securities of an “affiliate” as collateral for loans by the Bank to a borrower and (4) the purchase of assets from the Holding Company by the Bank. Further, a bank holding company and its subsidiaries are prohibited from engaging in certain tie-in arrangements in connection with any extension of credit, lease or sale of property or furnishing of services. 

Payment of Dividends

The Holding Company is a legal entity separate and distinct from the Bank. Most of the revenue of the Holding Company results from dividends paid to it by the Bank. There are statutory and regulatory requirements applicable to the payment of dividends and other distributions by the Bank, as well as by the Holding Company to its shareholders. 

Under the regulations of the GADBF, a Georgia state bank may declare a dividend out of its retained earnings without GADBF approval if it meets all the following requirements: 
(a)total classified assets as of the most recent examination of the bank do not exceed 80% of equity capital (as defined by regulation);
(b)the aggregate amount of dividends declared or anticipated to be declared in the calendar year does not exceed 50% of the net profits after taxes but before dividends for the previous calendar year; and
(c)the ratio of equity capital to adjusted assets is not less than 6%.

The payment of dividends by the Holding Company and the Bank may also be affected or limited by other factors, such as the requirement to maintain adequate capital above regulatory guidelines. In addition, if, in the opinion of the applicable regulatory authority, a bank under its jurisdiction is engaged in or is about to engage in an unsafe or unsound practice (which, depending upon the financial condition of the bank, could include the payment of dividends), such authority may require, after notice and hearing, that such bank cease and desist from such practice. The FDIC has issued a policy statement providing that insured banks should generally only pay dividends out of current operating earnings. In addition to the formal statutes and regulations, regulatory authorities consider the adequacy of the Bank’s total capital in relation to its assets, deposits and other such items. Capital adequacy considerations could further limit the availability of dividends from the Bank.
 
11


The Federal Reserve has issued a policy statement on the payment of cash dividends by bank holding companies, which expresses the Federal Reserve’s view that a bank holding company generally should pay cash dividends only to the extent that the holding company’s net income for the past year is sufficient to cover both the cash dividends and a rate of earnings retention that is consistent with the holding company’s capital needs, asset quality, and overall financial condition. The Federal Reserve has also indicated that a bank holding company should not maintain a level of cash dividends that places undue pressure on the capital of its bank subsidiaries, or that can be funded only through additional borrowings or other arrangements that undermine the bank holding company’s ability to act as a source of strength to its bank subsidiaries. The Holding Company and the Bank must also maintain the CET1 capital conservation buffer of 2.5% to avoid becoming subject to restrictions on capital distributions, including dividends, as described below under “Capital Adequacy-Basel III Capital Standards.”
 
During 2020 and 2018, the Bank paid cash dividends of $150 million and $162 million, respectively, to the Holding Company. In 2019, no cash dividends were paid by the Bank to the Holding Company. The Holding Company declared annual cash dividends on its common stock in 2020, 2019 and 2018 of $0.72, $0.68 and $0.58 per share, respectively.
 
Capital Adequacy

Banks and bank holding companies are subject to various regulatory capital requirements administered by state and federal banking agencies. Capital adequacy guidelines 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. 

Basel III Capital Standards

Regulatory capital rules adopted in July 2013 and fully-phased in as of January 1, 2019, which we refer to as the Basel III rules, impose minimum capital requirements for bank holding companies and banks. The Basel III rules apply to all national and state banks and savings associations regardless of size and bank holding companies and savings and loan holding companies with more than $3 billion in total consolidated assets.

Specifically, we are required to maintain the following minimum capital levels:

a CET1 risk-based capital ratio of 4.5%;
a Tier 1 risk-based capital ratio of 6%;
a total risk-based capital ratio of 8%; and
a leverage ratio of 4%.

Under Basel III, Tier 1 capital includes two components: CET1 capital and additional Tier 1 capital. The highest form of capital, CET1 capital, consists solely of common stock (plus related surplus), retained earnings, AOCI, and limited amounts of minority interests that are in the form of common stock. Additional Tier 1 capital is primarily comprised of noncumulative perpetual preferred stock, Tier 1 minority interests and grandfathered trust preferred securities (as discussed below). Tier 2 capital generally includes the ACL up to 1.25% of RWA, qualifying preferred stock, subordinated debt and qualifying tier 2 minority interests, less any deductions in Tier 2 instruments of an unconsolidated financial institution. Cumulative perpetual preferred stock is included only in Tier 2 capital, except that the Basel III rules permit bank holding companies with less than $15 billion in total consolidated assets to continue to include trust preferred securities and cumulative perpetual preferred stock issued before May 19, 2010 in Tier 1 Capital (but not in CET1 capital), subject to certain restrictions. AOCI is presumptively included in CET1 capital and often would operate to reduce this category of capital. When implemented, Basel III provided a one-time opportunity at the end of the first quarter of 2015 for covered banking organizations to opt out of much of this treatment of AOCI. We made this opt-out election and, as a result, retained our pre-existing treatment for AOCI.

In addition, in order to avoid restrictions on capital distributions or discretionary bonus payments to executives, under Basel III, a banking organization must maintain a “capital conservation buffer” on top of its minimum risk-based capital requirements. This buffer must consist solely of Tier 1 Common Equity, but the buffer applies to all three risk-based measurements (CET1, Tier 1 capital and total capital). The 2.5% capital conservation buffer was phased in incrementally over time, and became fully effective for us on January 1, 2019, resulting in the following effective minimum capital plus capital conservation buffer ratios: (i) a CET1 capital ratio of 7.0%, (ii) a Tier 1 risk-based capital ratio of 8.5%, and (iii) a total risk-based capital ratio of 10.5%.

On December 21, 2018, the federal banking agencies issued a joint final rule to revise their regulatory capital rules to (i) address the upcoming implementation of a new credit impairment model, or CECL, as part of an accounting standard under GAAP; (ii) provide an optional three-year phase-in period for the day-one adverse regulatory capital effects that banking organizations are expected to

experience upon implementing CECL; and (iii) require the use of CECL in stress tests beginning with the 2020 capital planning and stress testing cycle for certain banking organizations that are subject to stress testing. We adopted the CECL accounting standard on January 1, 2020 using the modified retrospective method for loans, leases, and off-balance sheet credit exposures. Adoption of this standard resulted in an $8.75 million increase in the ACL and a cumulative-effect adjustment to retained earnings of $3.53 million, net of tax, during the first quarter of 2020. For more information, see Note 2, Accounting Standards Updates and Recently Adopted Standards, in Part II, Item 8 of this Report - “Notes to Consolidated Financial Statements.”

In December 2017, the Basel Committee on Banking Supervision published the last version of the Basel III accord, generally referred to as “Basel IV.” The Basel Committee stated that a key objective of the revisions incorporated into the framework is to reduce excessive variability of RWA, which will be accomplished by enhancing the robustness and risk sensitivity of the standardized approaches for credit risk and operational risk, which will facilitate the comparability of banks’ capital ratios; constraining the use of internally modeled approaches; and complementing the risk-weighted capital ratio with a finalized leverage ratio and a revised and robust capital floor. Leadership of the federal banking agencies who are tasked with implementing Basel IV supported the revisions. Although it is uncertain at this time, we anticipate some, if not all, of the Basel IV accord may be incorporated into the capital requirements framework applicable to us.

Prompt Corrective Action

In addition to the Basel III rules applicable to both banks and bank holding companies discussed above, the Bank is required to comply with the capital requirements promulgated under the Federal Deposit Insurance Act and the prompt corrective action regulations thereunder, which set
