Specifically, we offer disability, life and voluntary products, on both individual and group bases, as well as provide certain fee-based services. These products and services, which can be sold stand-alone or combined with other coverages, help employers of all sizes attract and retain the talented and capable workforce they need to succeed while protecting the incomes and livelihood of their employees. We believe employer-sponsored benefits are the most effective way to provide workers with access to information and options to protect their financial stability. Working people and their families, particularly those at lower and middle incomes, are perhaps the most vulnerable to economic volatility yet are often overlooked by many providers of financial products and services. For many of these workers and families, employer-sponsored benefits are the primary defense against the potentially catastrophic financial impact of death, illness, or injury.

We have established a corporate culture consistent with the social value of our products and services. We see important links between the obligations we have to all of our stakeholders, and we place a strong emphasis on operating with integrity and contributing to positive change in our communities. Accordingly, we are committed not only to meeting the needs of our customers who depend on us, but also to being accountable for our actions through sound and consistent business practices, a strong internal compliance program, a comprehensive risk management strategy, and an engaged employee workforce.

We believe our disciplined approach to providing financial protection products at the workplace puts us in a position of strength. The products and services we provide have never been more important to employers, employees, and their families. Our strategy remains centered on growing our core businesses through investing and transforming our operations and technology to anticipate and respond to the changing needs of the marketplace, driving enhanced customer experiences and expanding into new adjacent markets through meaningful partnerships and effective deployment of our capital across our portfolio.

We continue to analyze and employ strategies we believe will help us navigate a variety of environments, allowing us to maintain financial flexibility to support the needs of our businesses and return capital to our shareholders. Our business has also proven resilient during less favorable environments, given the essential nature of our products and services, and our effective operating position.

We believe that consistent operating results, combined with the implementation of strategic initiatives and the effective deployment of capital, will allow us to meet our financial objectives.

Group Long-term and Short-term Disability

We sell group long-term and short-term disability products to employers for the benefit of employees.

Group long-term disability provides employees with insurance coverage for loss of income in the event of extended work absences due to sickness or injury. We offer services to employers and insureds to encourage and facilitate rehabilitation, retraining, and re-employment. Most policies begin providing benefits following 90 or 180 day waiting periods and continue providing benefits until the employee reaches a certain age, generally between 65 and 70, or recovers from the disability. The benefits are limited to specified maximums as a percentage of income. Also included in our long-term disability product line is our medical stop-loss product, which was no longer actively marketed as of the third quarter of 2024. As our medical stop-loss contracts were renewable on an annual basis, no medical stop-loss policies were in-force as of the fourth quarter of 2025. This product was designed to protect self-insured employers if their employees' medical claims exceed certain agreed upon thresholds.

Group short-term disability insurance generally provides coverage from loss of income due to injury or sickness for up to 26 weeks and is limited to specified maximums as a percentage of income. Benefits are typically effective after 0 to 30 days for accidents and after 7 to 30 days for sickness.

Table of Contents

Our fee-based services include leave management and administrative services only (ASO) business. Leave management services provide administrative services on behalf of employers to ensure the protected leave eligibility and status for employees are in accordance with applicable laws and regulations. ASO products provide administrative services regarding claims processing and billing for self-insured customers for which the responsibility for funding claim payments remains with the customer.

Premiums for group long-term and short-term disability are generally based on expected claims of a pool of similar risks plus provisions for administrative expenses, investment income, and profit. In some cases, coverage for large employers will include retrospective experience rating provisions or will be underwritten on an experience-rated basis. Premiums for experience-rated group long-term and short-term disability business are based on the expected experience of the client given its demographics, industry group, and location, adjusted for the credibility of the specific claim experience of the client. Both group long-term and short-term disability are sold primarily on a basis permitting periodic repricing to address the underlying claims experience. Fees for our leave management services and ASO business are generally based on the number of covered employees and an agreed-upon per-employee, per-month rate. Premiums for our medical stop-loss product were generally based on the number of covered employees in self-insured employer groups and their estimated overall health risk plus provisions for administrative expenses, and profit.

We have defined underwriting practices and procedures. If the coverage amount for our disability policies exceeds certain prescribed age and amount limits, we may require a prospective insured to submit evidence of insurability. Our disability policies are typically issued, both at inception and renewal, with rate guarantees. For new group policyholders, the usual rate guarantee is one to three years. For group policies being renewed, the rate guarantee is generally one year, but may be longer. The profitability of the policy depends on the adequacy of the rate during the rate guarantee period. The contracts provide for certain circumstances in which the rate guarantees can be overridden.

Profitability of group long-term and short-term disability insurance is affected by sales, persistency, investment returns, claims experience, and the level of administrative expenses. Morbidity is an important factor in disability claims experience, and many economic and societal factors can affect claim incidence for disability insurance. We routinely make pricing adjustments on our group long-term and short-term disability insurance products, when contractually permitted, which take into account emerging experience and external factors.

Group Life and Accidental Death and Dismemberment

Group life and accidental death and dismemberment products are sold to employers as employee benefit products. Group life consists primarily of renewable term life insurance with the coverages frequently linked to employees' wages and includes a provision for waiver of premium, if disabled. Accidental death and dismemberment consists primarily of an additional benefit amount payable if death or severe injury is attributable to an accident.

Premiums are generally based on expected claims of a pool of similar risks plus provisions for administrative expenses, investment income, and profit. Underwriting practices and rate guarantees are similar to those used for group disability products, and evidence of insurability is required for benefits in excess of a specified limit.

Profitability of group life and accidental death and dismemberment insurance is affected by persistency, investment returns, mortality and other claims experience, and the level of administrative expenses.

Voluntary Benefits

Voluntary benefits products are primarily sold to groups of employees through payroll deduction at the workplace and include accident, disability, life, hospital indemnity, cancer, and critical illness. Products are issued on both a group and individual basis.

Premiums are generally based on assumptions for morbidity, mortality, persistency, administrative expenses, investment income, and profit. We develop our assumptions based on our own experience and published industry tables. Our underwriters may evaluate the medical condition of prospective policyholders prior to the issuance of a policy on a simplified basis. However, underwriting requirements are often waived for cases that meet certain criteria, including participation levels. Individual voluntary benefits products other than life insurance are offered on a guaranteed renewable basis which allows us to

reprice in-force policies, subject to regulatory approval. Group voluntary benefits products are offered primarily on an optionally renewable basis which allows us to reprice or terminate in-force policies.

Profitability of voluntary benefits products is affected by the level of employee participation, persistency, investment returns, mortality and other claims experience, and the level of administrative expenses.

Individual Disability

Individual disability products are offered primarily to multi-life employer groups to supplement their group disability plans and may be funded by the employer, but the majority of our individual disability policies are entirely owned by the employee and are portable. Individual disability insurance provides the insured with a portion of earned income lost as a result of sickness or injury. The benefits, including the underlying group disability coverage, typically range from 30 percent to 75 percent of the insured's monthly earned income. We provide various options with respect to length of benefit periods, product features, and waiting periods before benefit payments begin, which permit tailoring of the multi-life plan to a specific employer's needs. We also market individual disability policies which include payments for the transfer of business ownership between partners and payments for business overhead expenses, also on a multi-life basis. Individual disability products do not provide for the accumulation of cash values.

Premium rates for individual disability products vary by age, product features, industry, region, and occupation based on assumptions concerning morbidity, mortality, persistency, administrative expenses, investment income, and profit. We develop our assumptions based on our own experience. Our underwriting rules, issue limits, and plan designs reflect risk and the financial circumstances of prospective insureds. Individuals in multi-life groups may be subject to limited medical underwriting. The majority of our individual disability policies are written on a noncancelable basis. Under a noncancelable policy, as long as the insured continues to pay the fixed annual premium for the policy's duration, we cannot cancel the policy or change the premium.

Profitability of individual disability insurance is affected by persistency, investment returns, claims experience, and the level of administrative expenses.

Dental and Vision

Group dental and vision products are sold to employers as employee benefit products. Our group dental products include a variety of insured and self-insured dental care plans including preferred provider organizations and scheduled reimbursement plans. Our group vision products provide coverage that includes a range of both in-network and out-of-network benefits for routine vision services offered either in conjunction with our dental product offerings or as stand-alone coverage.

Premiums for small case group dental and vision products are generally based on expected claims of a pool of similar risks plus a provision for administrative expenses, investment income, and profit. Premiums for large employer groups are underwritten on an experience-rated basis.

Profitability of our dental and vision products is affected by persistency, claims experience, the level of administrative expenses, and to a lesser extent, investment returns.

Unum International Segment

Our Unum International segment includes our operations in the United Kingdom and Poland. Unum UK's business includes insurance for group long-term disability, group life, and supplemental lines of business which include dental, individual disability, and critical illness products. Unum Poland's business primarily includes insurance for individual and group life with accident and health riders. Unum International's products are sold primarily through field sales personnel and independent brokers and consultants. The market strategy for the segment is to offer benefits to employers and employees through the workplace, with a focus on the expansion of the number of employers and employees covered in our Unum UK business, and the continued growth of the Unum Poland business.

Unum UK Group Life

Group life products are sold to employers as employee benefit products. Group life consists of two types of products, a renewable term life insurance product and a group dependent life product. The renewable term life product provides a lump sum benefit to the beneficiary upon the death of an employee. The group dependent life product, which we discontinued offering to new customers in 2012, provides an annuity to the beneficiary upon the death of an employee. Both coverages are frequently linked to employees' wages. Premiums for group life are generally based on expected claims of a pool of similar risks plus provisions for administrative expenses, investment income, and profit. Underwriting and rate guarantees are similar to those utilized for Unum UK group long-term disability products.

Profitability of group life is affected by sales, persistency, investment returns, mortality and other claims experience, and the level of administrative expenses.

Supplemental products are sold to employers and groups of employees and include group critical illness and group dental products. Group critical illness products provide a lump-sum benefit on the occurrence of a covered critical illness event. Group dental products generally provide fixed benefits based on specified treatments or a portion of the cost of the treatment.

Products are issued primarily by Colonial Life & Accident Insurance Company and marketed to employees, on both a group and an individual basis, at the workplace through an independent contractor agent sales force and brokers. Our market strategy for Colonial Life is to effectively deliver a broad set of voluntary products and services in the public sector and in the commercial sector, with a particular focus on the core market, which we define for Colonial Life as accounts with fewer than 1,000 employees.

Our underwriters evaluate the medical condition of prospective policyholders prior to the issuance of a policy on a simplified basis. Underwriting requirements may be waived for cases that meet certain criteria, including participation levels.

Premiums are generally based on assumptions for morbidity, mortality, persistency, administrative expenses, investment income, and profit. We develop our assumptions based on our own experience and published industry tables. Premiums are primarily individual guaranteed renewable which allows us to change premiums on a state by state basis. Some policies are written on a group basis which are offered primarily on an optionally renewable basis which allows us to reprice or terminate in-force policies. Premiums for our dental and vision products are guaranteed renewable with rates that may vary by age and region.

Profitability is affected by the level of employee participation, persistency, investment returns, claims experience, and the level of administrative expenses.

Closed Block Segment

Our Closed Block segment consists of group and individual long-term care and other insurance products no longer actively marketed. Closed Block segment premium income for 2025 was comprised of approximately 81 percent group and individual long-term care and 19 percent other insurance products.

Group and Individual Long-term Care

We discontinued offering individual long-term care in 2009 and group long-term care in 2012. As of July 2025, we closed the Fortitude Reinsurance Company Ltd. (Fortitude Re) reinsurance transaction and ceded a portion of the long-term care product line. As of February 2026, we discontinued new enrollments on existing group long-term care policies. Group long-term care was previously offered to employers for the benefit of employees. Individual long-term care was previously marketed on a single-life customer basis.

Long-term care insurance pays a benefit upon the loss of two or more activities of daily living and the insured's requirement of standby assistance or cognitive impairment. Payment is generally made on an indemnity basis, regardless of expenses incurred, up to a lifetime maximum. Benefits begin after a waiting period, usually 90 days or less, and are generally paid for a period of three years, six years, or lifetime.

Our long-term care insurance was sold on a guaranteed renewable basis which allows us to reprice in-force policies, subject to regulatory approval.

All Other

All other insurance products not actively marketed include individual disability, group pension, individual life and corporate-owned life insurance, reinsurance pools and management operations, and other miscellaneous product lines. The majority of these products have been reinsured, with approximately 85 percent of reserves at December 31, 2025 ceded to other insurance companies.

Corporate Segment

Our Corporate segment includes investment income on corporate assets not specifically allocated to a line of business, interest expense on corporate debt, and certain other corporate income and expenses not allocated to a line of business.

Reinsurance

In the normal course of business, we assume reinsurance from and cede reinsurance to other insurance companies. In a reinsurance transaction, a reinsurer agrees to indemnify another insurer for part or all of its liability under a policy or policies it has issued for an agreed upon premium or fee. We undertake reinsurance transactions for both risk management and capital management. If the assuming reinsurer in a reinsurance agreement is unable to meet its obligations, we remain contingently liable. In the event that reinsurers do not meet their obligations under the terms of the reinsurance agreement, reinsurance recoverable balances could become uncollectible. We evaluate the financial condition of reinsurers to whom we cede business and monitor concentration of credit risk to minimize our exposure. We may also require assets to be held in trust, letters of credit, or other acceptable collateral to support reinsurance recoverable balances. The collectability of our reinsurance recoverable is primarily a function of the solvency of the individual reinsurers. Although we have controls to minimize our exposure, the insolvency of a reinsurer or the inability or unwillingness of a reinsurer to comply with the terms of a reinsurance contract could have a material adverse effect on our results of operations.

In general, the maximum amount of life insurance risk retained by our U.S. insurance subsidiaries under group or individual life or group or individual accidental death and dismemberment policies during 2025 was $1.0 million per covered life per policy. The retention amount remains at $1.0 million for 2026. For Unum Limited life insurance risk, during 2025, we had reinsurance agreements which provided 15 percent quota share coverage for group lump sum benefits up to £500 thousand per covered life as well as 80 percent coverage per covered life for group lump sum benefits above £500 thousand up to £2.0 million. For Unum Limited, during 2026, we have reinsurance agreements which provide 10 percent quota share coverage for group lump sum benefits up to £500 thousand per covered life as well as 80 percent coverage per covered life for group lump sum benefits above £500 thousand up to £2.0 million. For Unum Limited, in 2025 and 2026, we have reinsured 100 percent of benefits in excess of £2.0 million for both group dependents and lump sum benefits.

We have global catastrophic reinsurance coverage which covers all Unum Group insurance companies and includes four layers of coverage to limit our exposure under life, accidental death and dismemberment, long-term care, and disability policies in regard to a catastrophic event. Each layer provides coverage for catastrophic events, including most acts of war and any type of terrorism, up to $4.0 million of coverage per person for each U.S. and Poland covered line of business, and up to £2.0 million of coverage for each U.K. covered line of business. We have the following coverage for 2026, after a $150 million deductible:

In addition to the global catastrophic reinsurance coverage noted above, Unum Limited has additional catastrophic coverage via an arms-length, intercompany reinsurance agreement with Unum America, under similar terms as the global catastrophic treaties. Unum Limited has the following additional coverage for 2026, after a £75.6 million deductible:

Unum Poland had additional global catastrophic reinsurance coverage of up to zł 100.0 million per event, or up to zł 200.0 million for the year, with a maximum retention limit of zł 2.0 million in 2025 and with a maximum retention limit of zł 2.5 million in 2026. Insurable events included passive war, as well as nuclear, chemical, biological and other forms of terrorism.

Events may occur which limit or eliminate the availability of catastrophic reinsurance coverage in future years.

Unum America cedes certain long-term care business to Fairwind Insurance Company (Fairwind), which is an affiliated captive reinsurance subsidiary (captive reinsurer) domiciled in the United States, with Unum Group as the ultimate parent. This captive reinsurer was established for the limited purpose of reinsuring risks attributable to specified policies issued or reinsured by Unum America in order to effectively manage risks in connection with this business as well as to enhance our capital efficiency. On a consolidated reporting basis for Unum Group, financial statement impacts of our reinsurance arrangements with affiliates are eliminated in accordance with U.S. generally accepted accounting principles (GAAP).

In February 2025, Unum America entered into a master transaction agreement with Fortitude Re, resulting in the execution of a coinsurance agreement (reinsurance agreement) in July 2025. This reinsurance agreement reinsures a portion of our Closed Block long-term care business and a portion of our Unum US individual disability business, on a coinsurance basis to Fortitude Re. The reinsurance agreement represented approximately 21 percent of total Closed Block long-term care future policy benefits and approximately 15 percent of Unum US individual disability future policy benefits as of December 31, 2024. Fortitude Re established and will maintain a collateralized trust account for the benefit of Unum America to secure its obligations under the reinsurance agreement.

Also in July 2025, prior to entering into this agreement with Fortitude Re, Unum America recaptured the aforementioned Closed Block long-term care business from Fairwind and assumed the aforementioned Unum US individual disability business from Provident, an affiliate.

We exited a substantial portion of our Closed Block individual disability product line through two phases of a coinsurance and modified coinsurance reinsurance transaction with Commonwealth Annuity and Life Insurance Company (Commonwealth) that were executed in December 2020 and March 2021. In addition, we also entered into an agreement with Commonwealth whereby we will provide a 12-year volatility cover to Commonwealth for the active life cohort (ALR cohort) ceded as a part of the reinsurance transaction described above. At the end of the 12-year coverage period, Commonwealth will retain the risk for the remaining incidence and claims risk on the ALR cohort of the ceded business. Due to the nature of the volatility cover, the ALR cohort is accounted for under the deposit method on a GAAP basis.

We have a quota share reinsurance agreement under which we cede certain blocks of Unum US group long-term disability claims. The agreement is on a combination coinsurance with funds withheld and modified coinsurance basis and provides 90 percent quota share reinsurance on the ceded claims. We also have five reinsurance agreements that collectively cede approximately 65 percent of Unum US group life risk up to our per person retention limit for our U.S. insurance subsidiaries. These reinsurance agreements for Unum US group disability and group life allow us to more effectively manage capital in conformity with statutory accounting principles but do not meet insurance risk transfer in accordance with applicable GAAP and therefore are not accounted for as reinsurance in our consolidated GAAP financial statements.

In 2024, we ceded 20 percent of the risk for certain blocks of recently issued Unum US individual disability policies, as well as some related claims development risk on a non-proportional modified coinsurance basis with a provision for experience refunds. This agreement terminated effective January 1, 2025. In 2025, we ceded 30 percent of the risk for most of our recently issued Unum US individual disability policies. This agreement is on a coinsurance with funds withheld basis with a

11

Table of Contents

provision for experience refunds. This agreement allows us to more effectively manage capital in conformity with statutory accounting principles but does not meet insurance risk transfer in accordance with applicable GAAP and therefore will not be accounted for as reinsurance in our consolidated GAAP financial statements.

For further discussion of our reinsurance activities, refer to "Risk Factors" contained herein in Item 1A; "Executive Summary," "Consolidated Operating Results," "Segment Results," and "Liquidity and Capital Resources - Cash Available from Subsidiaries" contained herein in Item 7, and Notes 1, 14, and 18 of the "Notes to Consolidated Financial Statements" contained herein in Item 8.

Liabilities for Future Policy Benefits

The applicable insurance laws under which insurance companies operate require that they report liabilities for future policy benefits to meet future obligations on their outstanding policies. These liabilities are the amounts which, with the additional premiums to be received and interest thereon compounded annually at certain assumed rates, are calculated to be sufficient to meet the various policy and contract obligations as they mature. These laws specify that the liabilities shall not be less than liabilities calculated using certain specified mortality and morbidity tables, interest rates, and methods of valuation required for statutory accounting.

The liabilities for future policy benefits reported in our financial statements contained herein are calculated in conformity with GAAP and differ from those specified by the laws of the various states and reported in the statutory financial statements of our insurance subsidiaries. These differences result from the use of mortality and morbidity tables which we believe are more representative of the expected experience for these policies than those required for statutory accounting purposes and also result from differences in actuarial reserving methods and interest rate assumptions.

The assumptions we use to calculate our liabilities are intended to represent an estimate of experience for the period that policy benefits are payable. Some of the key assumptions include the discount rate, the claim resolution rate, the claim incidence rate, and policyholder lapse and mortality. There are also some key assumptions that are applicable only to certain product lines. Cash flow assumptions are reviewed and updated, as needed, at least annually. Assumptions may be updated more frequently, if necessary, based on trending experience and future expectations. On a quarterly basis, cohort level cash flow measures are updated based on the emergence of actual experience.

The change in the liability for future policy benefits, at the original discount rate, as of the beginning of the period, resulting from changes in cash flow assumptions and resulting from the emergence of actual experience from expected experience, is reflected as the 'policy benefits - remeasurement loss (gain)' in the consolidated statements of income. The impact of all other changes in the liability for future policy benefits are reflected as policy benefits in the consolidated statements of income.

For further discussion of our liabilities for future policy benefits, refer to "Risk Factors" contained herein in Item 1A, "Critical Accounting Estimates", and the discussion of segment operating results included in "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained herein in Item 7, and Notes 1 and 6 of the "Notes to Consolidated Financial Statements" contained herein in Item 8.

Investments

Investment activities are an integral part of our business, and profitability is significantly affected by investment results. We segment our invested assets into portfolios that support our various product lines. Generally, our investment strategy for our portfolios is to match the effective asset cash flows and durations with related expected liability cash flows and durations to consistently meet the liability funding requirements of our businesses and to manage interest rate risk. We seek to earn investment income while assuming risk in a prudent and selective manner, subject to the constraints of quality, liquidity, diversification, and regulatory considerations. Our overall investment philosophy is to invest in a portfolio of high quality assets that provide investment returns which inform the assumptions embedded in the pricing of our insurance products. Assets are invested predominantly in fixed maturity securities.

We may redistribute investments among our different lines of business or sell selected securities and reinvest the proceeds, when necessary, to adjust the cash flow and/or duration of the asset portfolios to better match the cash flow and duration of the liability portfolios. Asset and liability portfolio modeling is updated on a quarterly basis and is used as part of the overall interest rate risk management strategy. Cash flows from the in-force asset and liability portfolios are projected at current

12

interest rate levels and at levels reflecting an increase and a decrease in interest rates to obtain a range of projected cash flows under the different interest rate scenarios. These results enable us to assess the impact of projected changes in cash flows and duration resulting from potential changes in interest rates. Testing the asset and liability portfolios under various interest rate scenarios enables us to choose what we believe to be the most appropriate investment strategy, as well as to limit the risk of disadvantageous outcomes. Although we test the asset and liability portfolios under various interest rate scenarios as part of our modeling, the majority of our liabilities related to insurance contracts are not interest rate sensitive, and we therefore have minimal exposure to policy withdrawal risk. Our determination of investment strategy relies on long-term measures, the relationship between the portfolio yields supporting our various product lines and the aggregate discount rate assumptions embedded in the reserves. We also utilize quantitative strategic asset analysis to construct our investment strategy, utilizing projected asset class risk and returns to inform an appropriate liability-driven investment approach. Additionally, we use this analysis in determining hedging strategies and utilizing derivative financial instruments to manage interest rate risk and the risk related to matching duration for our assets and liabilities. We do not use derivative financial instruments for speculative purposes.

Ratings

A.M. Best Company (AM Best), Fitch Ratings (Fitch), Moody's Ratings (Moody's), and S&P Global Ratings (S&P) are among the third parties that assign issuer credit ratings to Unum Group and financial strength ratings to our insurance subsidiaries. Issuer credit ratings reflect an agency's opinion of the overall financial capacity of a company to meet its senior debt obligations. Financial strength ratings are specific to each individual insurance subsidiary and reflect each rating agency's view of the overall financial strength (capital levels, earnings, growth, investments, business mix, operating performance, and market position) of the insuring entity and its ability to meet its obligations to policyholders. Both the issuer credit ratings and financial strength ratings incorporate quantitative and qualitative analyses by rating agencies and are routinely reviewed and updated on an ongoing basis.

Rating agencies assign an outlook statement of "positive," "negative," or "developing" to indicate an intermediate-term trend in credit fundamentals which could lead to a rating change. "Positive" means that a rating may be raised, "negative" means that a rating may be lowered, and "developing" means that a rating may be raised or lowered with equal probability. Alternatively, a rating may have a "stable" outlook to indicate that the rating is not expected to change.

"Credit watch" or "under review" highlights the potential direction of a short-term or long-term rating. It focuses on identifiable events and short-term trends that cause a rating to be placed under heightened surveillance by a rating agency. Events that may trigger this action include mergers, acquisitions, recapitalizations, regulatory actions, criteria changes, or operating developments. Ratings may be placed on credit watch or under review when an event or a change in an expected trend occurs and additional information is needed to evaluate the current rating level. This status does not mean that a rating change is inevitable, and ratings may change without first being placed on a watch list. A rating is not a recommendation to buy, sell, or hold securities and may be subject to revision or withdrawal at any time by the rating agency. Each rating should be evaluated independently of any other rating.
