We believe “Income from Continuing Operations, As Adjusted,” which is a non-GAAP financial measure and excludes realized investment gains and losses, which are recurring, and certain other items as specified, is a better performance measure and a better indicator of the profitability and underlying trends in our business. Realized investment gains and losses are primarily dependent on market conditions and general economic events and are not necessarily related to decisions regarding our underlying business. The exclusion of certain other items specified above also enhances the understanding and comparability of our performance and the underlying fundamentals in our operations, but this exclusion is not an indication that similar items may not recur. We also believe that book value per common share excluding accumulated other comprehensive income or loss, which also tends to fluctuate depending on market conditions and general economic trends, is an important measure. b 4356_2010AR_CovNar.indd 2 3/31/11 6:17 PM I’m pleased to report that 2010 was another strong year for our company. The actions we took almost a decade ago to instill greater discipline in all that we do – the discipline to focus on businesses and risks we understand, to maintain a “fortress” balance sheet, and to consistently execute on our plan – have continued to serve us well. Our success would not have been possible without the incredible efforts of our nearly 10,000 employees who enable us every day to deliver on our commitments. To Our Shareholders, Customers, and Colleagues In this year’s letter I’ll touch on our results, including some of the non-financial indicators that define Unum’s culture and have helped position us well for the future. I’ll also address the outlook for our industry – specifically the growing need for benefits offered in the workplace. Clearly there are both challenges and opportunities that lie ahead. I continue to believe Unum is well-positioned to navigate through the challenges and, at the same time, to seize on the significant opportunities that are emerging in today’s marketplace. 4356_2010AR_CovNar.indd 1 Thomas R.

Strong Five-Year Track Record Predictable results in an unPredictable environment The generally strong results we produced last year in spite of a difficult environment were possible because we continued to follow the playbook we established a number of years ago. While singularly focused on employee benefits in the workplace, we have continued to develop both geographic and product diversity, which has significantly reduced the risk in our business and contributed to our overall success. Among the highlights for last year: • Our operating earnings per share grew almost 5 percent in 2010 and has grown at a compound annual rate of 11 percent since 2006; • New accounts, which are an indication of how connected we are with our markets, grew more than 4 percent, and we continue to enjoy very strong customer retention; • Our continued outstanding operating performance, the quality of our investment portfolio, and the strength of our capital position enabled us to increase our dividend by 12 percent and, in early 2011, complete $500 million in share repurchases authorized in 2010 and announce an authorization for an additional $1 billion share repurchase over 18 months; • Our increased profitability and financial flexibility prompted upgrades in our financial strength ratings by both Fitch and Moody’s in 2010 and A.M. Best in early 2011. Such upgrades are uncommon among financial services providers in today’s challenging environment; • We continue to recognize that our success isn’t measured solely by financial results, but also by how well we treat our customers, employees, communities, and the environment. I’m very proud of our accomplishments in all of these areas. Importantly, we have continued to generate solid returns for our shareholders. Though the market remains somewhat volatile, our one-, three- and five-year total shareholder returns have outperformed our industry, the S&P 500, and the broader stock market – and we have every reason to believe this performance is sustainable.

More importantly, there are clear indications that there are significant longer-term to the continued low levels of employment in the U.S. growth opportunities in our business. As a market leader and U.K., to cost pressures confronting both businesses and in both the U.S. and U.K., we are well-positioned to be individuals.

However, we have provided in the past. While it’s difficult to know what the right strategy, people, and products to continue to lies ahead for government-provided benefits in the U.S. 4356_2010AR_CovNar.indd 3 3 3/31/11 6:17 PM and U.K., what is clear is that neither government is by providing access to a well-rounded likely to increase benefits. Instead, they will almost benefits package; certainly ask citizens to take more responsibility for protecting their own financial security. • More than 70 percent of life insurance and 80 percent of disability insurance is pur- chased in the workplace; Employer-sponsored benefits can play a major role • Middle- and lower-income families, in in addressing the need for financial protection and particular, are dependent on the workplace in taking the pressure off government resources. for benefits. According to recent economic studies, the protection provided by employer-sponsored disability insurance, In short, we believe the workplace is extremely for instance, means that as many as 430,000 families important today and, in the future, will become each year in the U.S. are not relying on public assistance an even more significant marketplace for providing programs. This translates into a savings to the govern- working people of all income levels access to ment and taxpayers of up to $3.5 billion a year.

With this in mind, benefits providers must – in partnership with employers and policymakers – step forward to help solve the problem of a large and rapidly expanding population without the financial resources to protect themselves or their families in the event of death, illness, or injury. Our research and industry data indicate that while some consumers have access to financial advice and sound choices to protect themselves, the vast majority do not – and in fact are looking to their employer for help. While employers are naturally concerned about cost pressures, they still see the value to their employees and to their businesses of providing financial protection benefits. In fact, most believe they have a responsibility to protect employees’ and their families’ well-being. The facts are compelling: • More than 80 percent of human resources executives say the key to keeping employees engaged and motivated is to demonstrate that the company cares about their well-being, and one of the ways they can do that is A CuLTure oF reSPoNSIbILITY As proud as I am of our financial results, I take even greater pride in the often-unnoticed actions of our people that define Unum’s culture as one of caring and striving to consistently do the right thing. Our people are highly engaged in the business, and as a result they make good things happen for all of our stakeholders. It begins with living up to our commit- ments to policyholders. In 2010, that meant paying approximately $6 billion in benefits to individuals and families during some of the most difficult times of their lives. Also ingrained in our company is the culture of responsibility we’ve fostered over the years. Our customer, broker, and claimant satisfaction numbers are at record levels and climbing. And we continue to believe that we have a significant role to play in assisting those less fortunate and in making our communities better, especially through our efforts to improve public education. Last year alone, Unum donated more than $7 million to charitable organiza- tions throughout the U.S. and U.K., including more than $1.2 million of employee contributions through our matching gifts program. We also advanced our commitment to good corporate citizenship by making further reductions in our carbon footprint. We recycled more than 3 million pounds of paper and cardboard and, since 2008, reduced our energy consumption by 15 percent. 4 4356_2010AR_CovNar.indd 4 3/31/11 6:17 PM unum uS unum uK #1 Group Disability #4 Group Life #3 Voluntary Benefit Sales #1 Group Income Protection #4 Group Life #1 Group Critical Illness Colonial Life #3 Voluntary Benefit Sales unum uS: Group Short-Term and Long-Term Disability in-force premium and cases: JHA 2009 U.S. Group Disability Market Survey; Group Life: In-force cases, JHA 2009 U.S. Group Life Market Survey unum uS and Colonial Life: Voluntary Benefits: Eastbridge U.S. Worksite Sales Report, Carrier Results for 2009, May 2010 unum uK: Swiss Re Group Watch 2010 Market Leadership For Future Growth We believe it’s also important as industry leaders In closing, we wouldn’t be where we are today to take a more active role in the political process, without the strong support of our board of directors particularly when it comes to informing our policy- and senior leadership team, and most especially the makers.

Sincerely, Thomas R. Watjen President and Chief Executive Officer ACHIevING our PoTeNTIAL In summary, I continue to be pleased with our performance, but I also recognize there is more we can do to realize Unum’s tremendous potential. The good news is that the opportunities exceed the challenges. I’m confident that through the continued focus and commitment of our people on doing what’s right, good things will continue to occur at this company. It’s rewarding to be in a position where there is a compelling need for what we do, where we have strong positions from which to operate, and where, when we execute well, our business generates solid margins and excess capital – capital to support growth, to fund corporate development, and also to generate returns for shareholders through dividends and stock buybacks. It’s a nice business model, and one that we believe will continue to serve our company and stakeholders well. 4356_2010AR_CovNar.indd 5 5 3/31/11 6:17 PM disability group life voluntary benefits 6 uNum uS group long-term care 4356_2010AR_CovNar.indd 6 3/31/11 6:17 PM Positioned to Deliver a Full Range of Financial Protection Solutions QA: Kevin McCarthy President and Chief Executive Officer Unum US what changes have most altered the benefits business? We all know the business of benefits has shifted a lot in recent years, and a challenging economic climate has only served to accelerate and intensify those changes. Employers who are working to build the best possible benefits plans for their employees are confronted these days by dilemmas at every turn. They’re worried about rising costs, they’re anxious to ensure they offer the range of benefits their employees need and want, and they’re confused by the possible effects of broad health care reform on the entire benefits picture. At the center of this challenging landscape is the move from a one-size-fits-all approach to benefits to a far more complex business that offers employees greater choice – and gives them more responsibility for picking up some of the cost of their coverage. Employers know competitive benefits are a must-have in recruiting and retaining a talented workforce, and the workplace is the primary source for valuable benefits coverage and education. That means employers are on the front lines of these changes in the benefits landscape and challenges in controlling costs. How have those changes defined unum’s focus? Employers rely on us more than ever to provide the right benefits, help them manage costs, and strengthen their connections with employees. We’re doing this by offering products and services that complement each other and provide a more complete approach to financial protection. Our integrated, simplified approach to benefits helps make costs more predictable and coverage more flexible. And we’ve worked steadily to strengthen the enrollment and education capabilities that help ensure employees understand and appreciate the benefits available to them. As a result of these investments, we stand apart from other benefits providers and distributors as a valued source of benefits expertise and guidance for employers and their employees. what unique strengths will help unum grow in the future? The broad range of Unum’s product and service offerings makes us a tremendously versatile benefits partner to both employers and their employees. From market-leading positions across group and voluntary coverages to services including FMLA administration and enrollment, Unum has an unmatched depth in its product and service portfolio. Our Simply Unum employee benefits platform – an integrated, simplified approach to benefits – has been extremely successful, especially in the small business market. We’re expanding the use of the platform to include new products and to expand benefits administration capabilities to larger employer groups. We’re also strengthening our focus on employee education, ease of enrollment, and building partnerships to create consumer- friendly benefits experiences across a broad spectrum – even beyond the benefits we provide. At our core, Unum is about building strong connections between employees and their employers through the benefits we provide. As the industry changes and the needs of our customers evolve, that unwavering focus is the foundation of our partnerships with our customers. 4356_2010AR_CovNar.indd 7 7 3/31/11 6:17 PM group life disability vocational rehabilitation voluntary benefits 8 uNum uK 4356_2010AR_CovNar.indd 8 3/31/11 6:17 PM A New Policy Dynamic Expands Opportunities to Serve QA: Jack McGarry President and Chief Executive Officer Unum UK How are economic and political changes impacting the benefits market in the u.K.? People in the U.K. have never had enough protection to start with. Now, with an unprecedented budget deficit to tackle, the government is cutting back on public spending, including welfare benefits for disabled people. This means that individuals will need to take more personal responsibility for their financial futures, especially given longer life spans and extended periods in work. Despite the acute need for a backup plan, around 90 percent of private-sector workers in the U.K. – nearly 16 million – do not have income protection insurance. The reasons for this are many and varied. A key factor is that employers often cover just senior and executive leadership and not the whole workforce. So what will be your focus over the next year? We have a fantastic opportunity to expand the market, and our leadership gives us a tremendous advantage. But to succeed, we need to systematically break down the barriers that have inhibited growth in coverage. Our strategy will be to: •    Educate employees and employers about the need for  financial protection and the risks they face if they don’t have adequate protection in place; •    Create flexible products and funding options to meet the  needs of employers and employees across their entire workforce; •    Be the best at what we do, delivering real value to our  customers and making a positive difference. How will unum respond to this new market opportunity? We can’t expect many companies to spend more on benefits right now. So finding ways to help an employer better balance their benefits and increase their perceived value will be a key focus for us. We recently introduced Unum Select, which brings exible funding and plan structures to market. It will enable employers to extend their financial protection benefits to their whole staff. fl Financial protection shouldn’t be a benefit only for executives earning high salaries. We want Unum to be widely known as the company that brought financial protection to all the working people in the U.K. 4356_2010AR_CovNar.indd 9 9 3/31/11 6:17 PM disability CoLoNIAL LIFe accident supplemental health life 10 4356_2010AR_CovNar.indd 10 3/31/11 6:17 PM Targeting Solutions to Meet the Needs of an Evolving Workplace QA: Randy Horn President and Chief Executive Officer Colonial Life about their benefits. This improves their financial literacy and helps them make choices to strengthen their personal financial safety net. Our enrollment support also relieves tremendous pressure from overburdened HR staffs and helps ensure workers understand the significant investment their employers are making in them, as well as the tough choices they’ve sometimes had to make. At the same time, the personal insurance products we offer meet the growing need for affordable, customizable protection. what role do you see for Colonial Life in the marketplace of the future? Voluntary products will continue to play an essential role in helping businesses offer competitive, cost-effective benefits packages and in helping employees meet the unique needs of their families. The demand for information – how and when customers want it – is growing exponentially, so our ability to offer effective, personalized communication will be key. And as part of a growing and financially strong organization, I see Colonial Life there in the future to keep the promises we make today. what are the biggest challenges in the employee benefits marketplace? It’s easy to bundle up the challenges our customers and our industry are facing and lay them on the doorstep of health care reform and the economy, but actually a lot of what we’re seeing today has been happening gradually for many years. The biggest is cost: A decade of double-digit health care cost increases leaves employers struggling to maintain their benefits packages, and employees are finding more of the financial burden is shifting to them. This financial pressure leads to another challenge – the shrinking financial safety net of many working Americans. Levels of life insurance coverage in the U.S. are at their lowest in years, and many others have no protection for their most valuable financial asset – the ability to earn an income. Both of these play into a third challenge – confusion and poor understanding of their benefits by employees. With so much changing so quickly, and with dwindling human resources staffs to educate them, many employees don’t understand their benefits options, the financial impact of their decisions, and how to make the best choices to protect themselves and their families. How is Colonial Life uniquely positioned to help businesses and their workers with these challenges? Benefits counseling is embedded into our business model. More than 70 years of experience and surveys with thousands of customers have shown us that sitting down one-to-one, face-to-face is the most effective way to educate employees 4356_2010AR_CovNar.indd 11 11 3/31/11 6:17 PM capital management financial strength unum Group 12 4356_2010AR_CovNar.indd 12 3/31/11 6:17 PM Financial Strength and Flexibility for the Future QA: Rick McKenney Executive Vice President and Chief Financial Officer Unum Group unum has built shareholder value in recent years through dividend increases and share repurchases. do you intend to continue with this capital management strategy? The consistency of our operating performance, the quality of our investment portfolio, and the strength of our capital position have enabled us to increase dividends and announce $1.5 billion in share repurchase authorizations over the last two years. These actions speak to the confidence we have in our businesses continuing to generate the kind of capital we’ve built over the last few years. We’re continuously looking for ways to take excess capital and invest it for growth, both in our current businesses and new opportunities, as well as to return it to shareholders when it makes sense. We intend to stick with this strategy, which has served us well. Our strong financial position is a direct result of the effective management of these risks, and ongoing risk management will continue to be a core competency. To what do you attribute recent ratings upgrades, particularly when downgrades among financial services providers are far more common? The ratings upgrades we’ve received have been especially gratifying given the success we’ve had in maintaining a strong franchise during an uncertain economic environment. The upgrades speak to the confidence the rating agencies have in our company, and we are going to continue to work to demonstrate that the strength and consistency of our business model warrants even higher ratings going forward. what steps does unum take to manage risks? Risk management forms the foundation for all of our decisions. From an operations perspective, we make conscious efforts to diversify our earnings sources by targeting certain sectors, employee populations and product lines. We also understand the importance of a strong risk management culture – it’s a part of everyone’s job. For example, we emphasize the value of prudent underwriting, pricing discipline, and quality claims management. In addition, Unum’s investment operation relies on fundamental credit analysis to manage our portfolio to meet the needs of policyholders and avoid unnecessary risks. All these actions are supported by thorough, ongoing risk and capital analysis and executed within the context of a robust Enterprise Risk Management framework. with the economy beginning to show signs of a turnaround, how does this affect unum’s growth prospects? Our performance has been consistent throughout the economic crisis due to our philosophy of taking responsible investment and underwriting risks, managing expenses prudently, and maintaining the capital to withstand market downturns. In spite of the environ- ment, we have seen good momentum in target markets such as voluntary benefits and core market commercial sales. As the economy improves, we’re confident that a rising number of customer relationships and the return to modest employment growth will have a positive impact on our premium growth. In addition, fiscal pressures on the U.S. and U.K. governments will create new opportunities for private sector solutions. 4356_2010AR_CovNar.indd 13 13 3/31/11 6:17 PM Directors and Officers Senior Officers Thomas R.

Executive Summary During 2010, our focus remained on disciplined top-line growth and capital management. Objectives for the year included: • Consistently execute our operating plans with an emphasis on disciplined, profitable growth. • Further enhance financial flexibility through solid operating and investment performance, as well as a disciplined approach to capital management. • Continue to invest in our business, including our products and services, as well as in the professional development of our employees. • Remain positioned to capitalize on long-term growth opportunities in the marketplace. A discussion of our operating performance and capital management follows. 2010 Operating Performance and Capital Management For 2010 we reported net income per share, assuming dilution, of $2.71 compared to $2.57 in 2009. After-tax operating income was $2.69 per share compared to $2.57 per share in 2009. Our operating revenue by segment increased 0.9 percent over 2009, with the current economic environment continuing to negatively impact our premium growth. Operating income by segment increased 2.0 percent over 2009, with solid performance in many of our product lines. See “Reconciliation of Non-GAAP Financial Measures” contained herein. Our Unum US segment reported an increase in segment operating income of 6.6 percent in 2010 compared to 2009, with the overall risk experience across our product lines remaining generally stable. The benefit ratio for the Unum US segment for 2010 was 79.3 percent compared to 79.1 percent in 2009, with year over year improvement in benefit ratios for group disability and voluntary benefits slightly offset by the higher benefit ratio in the individual disability — recently issued and long-term care product lines. Unum US premium income decreased slightly in 2010 compared to 2009. Similar to 2009, the ongoing high levels of unemployment and the competitive environment continued to pressure our sales and premium income growth. In particular, premium growth from existing customers continued to be unfavorably impacted by lower salary growth and lower growth in the number of employees covered under an existing policy. Partially offsetting this unfavorable impact on premium growth was higher persistency. Unum US sales, which were also negatively impacted by the economy and the competitive environment, decreased 5.7 percent in 2010 compared to 2009. Our group core market segment, which we define for Unum US as employee groups with fewer than 2,000 lives, reported a sales decline of 8.3 percent in 2010 relative to 2009. Sales in the group large case market segment in 2010 declined 19.8 percent compared to 2009. Sales of voluntary benefits increased 15.6 percent in 2010 compared to 2009. Persistency for all product lines remains high relative to historical levels. Our Unum UK segment reported a decrease in segment operating income of 15.8 percent in 2010, as measured in Unum UK’s local currency, relative to last year. The decrease was driven by a decline in premium income as well as less favorable risk results. The decline in premium income resulted from lower premium growth from existing customers and pricing actions due to the competitive U.K. market. The benefit ratio for Unum UK was 67.0 percent in 2010 compared to 54.5 percent in 2009, driven primarily by lower premium income, the impact of higher inflation on claim reserves associated with group long-term disability policies containing an inflation-linked benefit increase feature, and unfavorable claim experience in group life. Overall sales in Unum UK were generally consistent with the prior year, with a decline of 0.9 percent in 2010, as measured in Unum UK’s local currency. Negatively affecting year over year comparisons is an increase in 2009 sales which resulted from the exit of another large insurance provider from the U.K. group risk market. Persistency generally improved over the levels of last year. 18 4356_2010AR_Fin_ALL.indd 18 4/4/11 3:05 PM Unum 2010 Annual Report Our Colonial Life segment reported a slight increase in segment operating income of 0.5 percent in 2010 relative to 2009, with premium growth of 6.0 percent relative to last year. Risk results were less favorable than last year, with a benefit ratio of 49.7 percent in 2010 compared to 47.3 percent in 2009, driven primarily by unfavorable experience in the accident, sickness, and disability product line. Colonial Life’s sales increased 4.4 percent relative to 2009. The number of new accounts and new agent contracts both increased relative to the prior year, while the average new case size declined. Persistency continues to remain strong and is slightly higher than the levels of 2009. Our investment portfolio continued to perform well, with an increase in net investment income of 6.3 percent over 2009. The net unrealized gain on our fixed maturity securities was $3.5 billion at the end of 2010, compared to a gain of $2.0 billion at year end 2009. We believe our capital and financial positions are strong. At the end of 2010, the risk-based capital ratio for our traditional U.S. insurance subsidiaries, calculated on a weighted average basis using the NAIC Company Action Level formula, was approximately 398 percent, compared to 382 percent at the end of 2009. Our leverage ratio, when calculated using consolidated debt to total consolidated capital, was 25.9 percent at December 31, 2010 compared to 24.8 percent at December 31, 2009, reflecting the issuance of $400.0 million of senior notes during the third quarter of 2010. Our leverage ratio, when calculated excluding the non-recourse debt and associated capital of Tailwind Holdings, LLC (Tailwind Holdings) and Northwind Holdings, LLC (Northwind Holdings), was 22.8 percent at December 31, 2010 compared to 20.5 percent at the end of 2009. The cash and marketable securities at our holding companies equaled approximately $1.2 billion at the end 2010, compared to $915 million at the end of 2009. During 2010, we repurchased 16.4 million shares of Unum Group’s common stock under our $500.0 million share repurchase program, at a cost of approximately $356.0 million. In February 2011, our board of directors authorized the repurchase of up to $1.0 billion of Unum Group’s common stock over the next 18 months, in addition to the amount remaining to be repurchased under the $500.0 million program. Despite the difficult economic environment, we continue to make steady and disciplined progress, executing on our business plans and strengthening our financial position. We remain cautious of the near-term outlook for employment levels and wages, both of which limit opportunities for premium growth, but we believe we are poised to profitably grow as employment trends improve. Further discussion is included in “Segment Results,” “Investments,” and “Liquidity and Capital Resources” contained herein. Outlook for 2011 During 2011, our focus will remain on disciplined top-line growth and capital management. Objectives for the year include: • Continue to consistently execute against our operating plans, which emphasize disciplined, profitable growth; • Further enhance our financial flexibility through solid operating and investment performance and a sustainable capital deployment strategy; • Leverage our capabilities, products, relationships, and reputation to deliver on our commitments as well as our bottom-line targets; • Continue to invest in our businesses and leverage global capabilities to capitalize on current and future growth opportunities. Critical Accounting Estimates We prepare our financial statements in accordance with GAAP. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in our financial statements and accompanying notes. The accounting estimates we deem to be most critical to our results of operations and balance sheets are those related to reserves for policy and contract benefits, deferred acquisition costs, valuation of investments, pension and postretirement benefit plans, income taxes, and contingent liabilities. Estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed in our financial statements. For additional information, refer to our significant accounting policies in Note 1 of the “Notes to Consolidated Financial Statements.” 4356_2010AR_Fin_ALL.indd 19 19 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Reserves for Policy and Contract Benefits Our largest liabilities are reserves for claims that we estimate we will eventually pay to our policyholders. The two primary categories of reserves are policy reserves for claims not yet incurred and claim reserves for claims that have been incurred or are estimated to have been incurred but not yet reported to us. These reserves equaled $38.2 billion and $37.8 billion at December 31, 2010 and 2009, respectively, or approximately 78.9 percent and 82.3 percent of our total liabilities, respectively. Reserves ceded to reinsurers were $6.7 billion at both December 31, 2010 and 2009, and are reported as reinsurance recoverable in our consolidated balance sheets. Policy Reserves Policy reserves are established in the same period we issue a policy and equal the difference between projected future policy benefits and future premiums, allowing a margin for expenses and profit. These reserves relate primarily to our traditional non interest-sensitive products, including our individual disability, individual and group long-term care, and voluntary benefits products in our Unum US segment; individual disability products in our Unum UK segment; disability and cancer and critical illness policies in our Colonial Life segment; and, the Individual Disability — Closed Block segment products. The reserves are calculated based on assumptions that were appropriate at the date the policy was issued and are not subsequently modified unless the policy reserves become inadequate (i.e., loss recognition occurs). • Persistency assumptions are based on our actual historical experience adjusted for future expectations. • Claim incidence and claim resolution rate assumptions related to mortality and morbidity are based on actual experience or industry standards adjusted as appropriate to reflect our actual experience and future expectations. • Discount rate assumptions are based on our current and expected net investment returns. In establishing policy reserves, we use assumptions that reflect our best estimate while considering the potential for adverse variances in actual future experience, which results in a total policy reserve balance that has an embedded reserve for adverse deviation. We do not, however, establish an explicit and separate reserve as a provision for adverse deviation from our assumptions. We perform loss recognition tests on our policy reserves annually, or more frequently if appropriate, using best estimate assumptions as of the date of the test, without a provision for adverse deviation. We group the policy reserves for each major product line within a segment when we perform the loss recognition tests. If the policy reserves determined using these best estimate assumptions are higher than our existing policy reserves net of any deferred acquisition cost balance, the existing policy reserves are increased or deferred acquisition costs are reduced to immediately recognize the deficiency. Thereafter, the policy reserves for the product line are calculated using the same method we used for the loss recognition testing, referred to as the gross premium valuation method, wherein we use our best estimate as of the gross premium valuation (loss recognition) date rather than the initial policy issue date to determine the expected future claims, commissions, and expenses we will pay and the expected future gross premiums we will receive. Because the key policy reserve assumptions for policy persistency, mortality and morbidity, and discount rates are all locked in at policy issuance based on assumptions appropriate at that time, policy reserve assumptions are not changed due to a change in claim status from active to disabled subsequent to policy issuance. Therefore, we maintain policy reserves for a policy for as long as the policy remains in-force, even after a separate claim reserve is established. Incidence rates in industry standard valuation tables for policy reserves have traditionally included all lives, active and disabled. In addition, the waiver of premium provision provides funding for the policy reserve while a policyholder is disabled. As a result, the funding mechanisms and the cost of claims are aligned and require a policy reserve to be held while on claim. In addition, most policies allow for multiple occurrences of claims, and a policy reserve is consequently still maintained at the time of claim to fund any potential future claims. The policy reserves build up and release over time based on assumptions made at the time of policy issuance such that the reserve is eliminated as policyholders reach the terminal age for coverage, die, or voluntarily lapse the policy. 20 4356_2010AR_Fin_ALL.indd 20 4/4/11 3:05 PM Unum 2010 Annual Report Policy reserves for Unum US, Unum UK, and Colonial Life products, which at December 31, 2010 represented approximately 40.0 percent, 0.2 percent, and 9.5 percent, respectively, of our total gross policy reserves, are determined using the net level premium method as prescribed by GAAP. In applying this method, we use, as applicable by product type, morbidity and mortality incidence rate assumptions, claim resolution rate assumptions, and policy persistency assumptions, among others, to determine our expected future claim payments and expected future premium income. We then apply an interest, or discount, rate to determine the present value of the expected future claims and claim expenses we will pay and the expected future premiums we will receive, with a provision for profit allowed. Policy reserves for our Individual Disability — Closed Block segment, which at December 31, 2010 represented approximately 9.0 percent of our total gross policy reserves, are determined using the gross premium valuation method based on assumptions established as of January 1, 2004, the date of loss recognition. Key assumptions are policy persistency, claim incidence, claim resolution rates, commission rates, and maintenance expense rates. We then apply an interest, or discount, rate to determine the present value of the expected future claims, commissions, and expenses we will pay as well as the expected future premiums we will receive, with no provision for future profit. The interest rate is based on our expected net investment returns on the investment portfolio supporting the reserves for this segment. Under the gross premium valuation method, we do not include an embedded provision for the risk of adverse deviation from these assumptions. Gross premium valuation assumptions do not change after the date of loss recognition unless reserves are again determined to be deficient. We perform loss recognition tests on the policy reserves for this block of business quarterly. The Corporate and Other segment includes certain products no longer actively marketed, the majority of which have been reinsured. Policy reserves for this segment represent $5.7 billion on a gross basis, or approximately 41.3 percent, of our total policy reserves. We have ceded $4.4 billion of the related policy reserves to reinsurers. The ceded reserve balance is reported in our consolidated balance sheets as a reinsurance recoverable. We continue to service a block of group pension products, which we have not ceded, and the policy reserves for these products are based on expected mortality rates and retirement rates. Expected future payments are discounted at interest rates reflecting the anticipated investment returns for the assets supporting the liabilities. Claim Reserves Claim reserves are established when a claim is incurred or is estimated to have been incurred but not yet reported (IBNR) to us and, as prescribed by GAAP, equals our long-term best estimate of the present value of the liability for future claim payments and claim adjustment expenses. A claim reserve is based on actual known facts regarding the claim, such as the benefits available under the applicable policy, the covered benefit period, and the age and occupation of the claimant, as well as assumptions derived from our actual historical experience and expected future changes in experience for factors such as the claim duration and discount rate. Reserves for IBNR claims, similar to incurred claim reserves, include our assumptions for claim duration and discount rates but because we do not yet know the facts regarding the specific claims, are also based on historical incidence rate assumptions, including claim reporting patterns, the average cost of claims, and the expected volumes of incurred claims. Our incurred claim reserves and IBNR claim reserves do not include any provision for the risk of adverse deviation from our assumptions. Claim reserves, unlike policy reserves, are subject to revision as current claim experience and projections of future factors affecting claim experience change. Each quarter we review our emerging experience to ensure that our claim reserves are appropriate. If we believe, based on our actual experience and our view of future events, that our long-term assumptions need to be modified, we adjust our reserves accordingly with a charge or credit to our current period income. Multiple estimation methods exist to establish claim reserve liabilities, with each method having its own advantages and disadvantages. Available reserving methods utilized to calculate claim reserves include the tabular reserve method, the paid development method, the incurred loss development method, the count and severity method, and the expected claim cost method. No single method is better than the others in all situations and for all product lines. The estimation methods we have chosen are those that we believe produce the most reliable reserves. 4356_2010AR_Fin_ALL.indd 21 21 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Claim reserves supporting our Unum US group and individual disability and group and individual long-term care lines of business and our Individual Disability — Closed Block segment represent approximately 39.5 percent and 43.7 percent, respectively, of our total claim reserves at December 31, 2010. We use a tabular reserve methodology for group and individual long-term disability and group and individual long-term care claims that have been reported. Under the tabular reserve methodology, reserves for reported claims are based on certain characteristics of the actual reported claimants, such as age, length of time disabled, and medical diagnosis. We believe the tabular reserve method is the most accurate to calculate long-term liabilities and allows us to use the most available known facts about each claim. IBNR claim reserves for our long-term products are calculated using the count and severity method using historical patterns of the claims to be reported and the associated claim costs. For group short-term disability products, an estimate of the value of future payments to be made on claims already submitted, as well as IBNR claims, is determined in aggregate rather than on the individual claimant basis that we use for our long-term products, using historical patterns of claim incidence as well as historical patterns of aggregate claim resolution rates. The average length of time between the event triggering a claim under a policy and the final resolution of those claims is much shorter for these products than for our long-term liabilities and results in less estimation variability. Claim reserves supporting the Unum US group life and accidental death and dismemberment products represent approximately 3.8 percent of our total claim reserves at December 31, 2010. Claim reserves for these products are related primarily to death claims reported but not yet paid, IBNR death claims, and a liability for waiver of premium benefits. The death claim reserve is based on the actual face amount to be paid, the IBNR reserve is calculated using the count and severity method, and the waiver of premium benefits reserve is calculated using the tabular reserve methodology. Claim reserves supporting our Unum UK segment represent approximately 9.0 percent of our total claim reserves at December 31, 2010, and are calculated using generally the same methodology that we use for Unum US disability and group life reserves. The assumptions used in calculating claim reserves for this line of business are based on standard United Kingdom industry experience, adjusted for Unum UK’s own experience. The majority of the Colonial Life segment lines of business have short-term benefits, which generally have less estimation variability than our long-term products because of the shorter claim payout period. Our claim reserves for Colonial Life’s lines of business, which approximate 1.3 percent of our total claim reserves at December 31, 2010, are predominantly determined using the incurred loss development method based on our own experience. The incurred loss development method uses the historical patterns of payments by loss date to predict future claim payments for each loss date. Where the incurred loss development method may not be appropriate, we estimate the incurred claims using an expected claim cost per policy or other measure of exposure. The key assumptions for claim reserves for the Colonial Life lines of business are: (1) the timing, rate, and amount of estimated future claim payments; and (2) the estimated expenses associated with the payment of claims. The following table displays policy reserves, incurred claim reserves, and IBNR claim reserves by major product line, with the summation of the policy reserves and claim reserves shown both gross and net of the associated reinsurance recoverable. Incurred claim reserves represent reserves determined for each incurred claim and also include estimated amounts for litigation expenses and other expenses associated with the payment of the claims as well as provisions for claims which we estimate will be reopened for our long-term care products. IBNR claim reserves include provisions for incurred but not reported claims and a provision for reopened claims for our disability products.

Of these assumptions, our discount rate and claim resolution rate assumptions have historically had the most significant effects on our level of reserves because many of our product lines provide benefit payments over an extended period of time. 1. The discount rate, which is used in calculating both policy reserves and incurred and IBNR claim reserves, is the interest rate that we use to discount future claim payments to determine the present value. A higher discount rate produces a lower reserve. If the discount rate is higher than our future investment returns, our invested assets will not earn enough investment income to support our future claim payments. In this case, the reserves may eventually be insufficient. We set our assumptions based on our current and expected future investment yield of the assets supporting the reserves, considering current and expected future market conditions. If the investment yield on new investments that are purchased is below or above the investment yield of the existing investment portfolio, it is likely that the discount rate assumption on claims will be established to reflect the effect of the new investment yield. 2. The claim resolution rate, used for both policy reserves and incurred and IBNR claim reserves, is the probability that a disability claim will close due to recovery or death of the insured. It is important because it is used to estimate how long benefits will be paid for a claim. Estimated resolution rates that are set too high will result in reserves that are lower than they need to be to pay the claim benefits over time. Claim resolution assumptions involve many factors, including the cause of disability, the policyholder’s age, the type of contractual benefits provided, and the time since initially becoming disabled. We use our own claim experience to develop our claim resolution assumptions. These assumptions are established for the probability of death and the probability of recovery from disability. Our studies review actual claim resolution experience over a number of years, with more weight placed on our experience in the more recent years. We also consider any expected future changes in claim resolution experience. 3. The incidence rate, used for policy reserves and IBNR claim reserves, is the rate at which new claims are submitted to us. The incidence rate is affected by many factors, including the age of the insured, the insured’s occupation or industry, the benefit plan design, and certain external factors such as consumer confidence and levels of unemployment. We establish our incidence assumption using a historical review of actual incidence results along with an outlook of future incidence expectations. Establishing reserve assumptions is complex and involves many factors. Reserves, particularly for policies offering insurance coverage for long-term disabilities, are dependent on numerous assumptions other than just those presented in the preceding discussion. The impact of internal and external events, such as changes in claims management procedures, economic trends such as the rate of unemployment and the level of consumer confidence, the emergence of new diseases, new trends and developments in medical treatments, and legal trends and legislative changes, among other factors, will influence claim incidence and resolution rates. Reserve assumptions differ by product line and by policy type within a product line. Additionally, in any period and over time, our actual experience may have a positive or negative variance from our long-term assumptions, either singularly or collectively, and these variances may offset each other. We test the overall adequacy of our reserves using all assumptions and with a long-term view of our expected experience over the life of a block of business rather than test just one or a few assumptions independently that may be aberrant over a short period of time. Therefore it is not possible to bifurcate the assumptions to evaluate the sensitivity of a change in each assumption, but rather in the aggregate by product line. We have presented in the following section an overview of our trend analysis for key assumptions and the results of variability in our assumptions, in aggregate, for the reserves which we believe are reasonably possible to have a material impact on our future financial results if actual claims yield a materially different amount than what we currently expect and have reserved for, either favorable or unfavorable. Trends in Key Assumptions Because our actual experience regarding persistency and claim incidence has varied very little from our policy reserve and IBNR claim reserve assumptions, we have had minimal adjustments to our persistency assumptions and claim incidence assumptions during the years 2008 through 2010. Generally, we do not expect our mortality and morbidity claim incidence trends or our persistency trends to change 24 4356_2010AR_Fin_ALL.indd 24 4/4/11 3:05 PM Unum 2010 Annual Report significantly in the short-term, and to the extent that these trends do change, we expect those changes to be gradual over a longer period of time. However, we have historically experienced an increase in our group long-term disability morbidity claim incidence trends during and following a recessionary period, particularly in our Unum US operations. During 2010, claim incidence rates for Unum US group long- term disability were slightly elevated. Given the current economic conditions, it is possible that our claim incidence rates for this type of product may increase. Throughout the period 2008 to 2010, actual new money interest rates varied with the changing market conditions, and the assumptions we used to discount our reserves generally trended downward slightly for all segments and product lines. Reserve discount rate assumptions for new policies and new claims have been adjusted to reflect our current and expected net investment returns. Changes in our average discount rate assumptions tend to occur gradually over a longer period of time because of the long-duration investment portfolio needed to support the reserves for the majority of our lines of business. Both the mortality rate experience and the retirement rate experience for our block of group pension products have remained stable and consistent with expectations. Claim resolution rates have a greater chance of significant variability in a shorter period of time than our other reserve assumptions. These rates are reviewed on a quarterly basis for the death and recovery components separately. Claim resolution rates in our Unum US segment group and individual long-term disability product lines and our Individual Disability — Closed Block segment have over the last several years exhibited some variability. Relative to the resolution rate we expect to experience over the life of the block of business, actual quarterly rates during 2009 and 2010 have varied by +3 and -4 percent in our Unum US group long-term disability line of business, between +10 and -12 percent in our Unum US individual disability — recently issued line of business, and between +5 and -3 percent in our Individual Disability — Closed Block segment. Claim resolution rates are very sensitive to operational and environmental changes and can be volatile over short periods of time. Throughout the period 2008 to 2010, we had generally stable to improving claims management performance, and our claim resolution rates were fairly consistent with or slightly favorable to our long-term assumptions. Our claim resolution rate assumption used in determining reserves is our expectation of the resolution rate we will experience over the life of the block of business and will vary from actual experience in any one period, both favorably and unfavorably. We monitor and test our reserves for adequacy relative to all of our assumptions in the aggregate. In our estimation, scenarios based on reasonably possible variations in each of our reserve assumptions, when modeled together in aggregate, could produce a potential result, either positive or negative, in our Unum US group disability line of business that would change our reserve balance by +/- 2.5 percent. Using our actual claim reserve balance at December 31, 2010, this variation would have resulted in an approximate change (either positive or negative) of $200 million to our claim reserves. Using the same sensitivity analysis approach for our Individual Disability — Closed Block segment, the claim reserve balance could potentially vary by +/- 2.6 percent of our reported balance, which at December 31, 2010, would have resulted in an approximate change (either positive or negative) of $260 million to our claim reserves. The major contributor to the variance for both the group long-term disability line of business and the Individual Disability — Closed Block segment is the claim resolution rate. We believe that these ranges provide a reasonable estimate of the possible changes in reserve balances for those product lines where we believe it is possible that variability in the assumptions, in the aggregate, could result in a material impact on our reserve levels, but we record our reserves based on our long-term best estimate. Because these product lines have long-term claim payout periods, there is a greater potential for significant variability in claim costs, either positive or negative. Deferred Acquisition Costs (DAC) We defer certain costs incurred in acquiring new business and amortize (expense) these costs over the life of the related policies. Deferred costs include certain commissions, other agency compensation, selection and policy issue expenses, and field expenses. Acquisition costs that do not vary with the production of new business, such as commissions on group products which are generally level throughout the life of the policy, are excluded from deferral. 4356_2010AR_Fin_ALL.indd 25 25 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Approximately 87.6 percent of our DAC relates to traditional non interest-sensitive products, and we amortize DAC in proportion to the premium income we expect to receive over the life of the policies. Key assumptions used in developing the future amortization of DAC are future persistency and future premium income. We use our own historical experience and expectation of the future performance of our businesses in determining the expected persistency and premium income. The estimated premium income in the early years of the amortization period is generally higher than in the later years due to the anticipated cumulative effect of policy persistency in the early years, which results in a greater proportion of the costs being amortized in the early years of the life of the policy. During 2010, our key assumptions used to develop the future amortization did not change materially from those used in 2009. Generally, we do not expect our persistency or interest rates to change significantly in the short-term, and to the extent that these trends do change, we expect those changes to be gradual over a longer period of time. Presented below are our current assumptions regarding the length of our amortization periods, the approximate DAC balance that remains at the end of years 3, 10, and 15 as a percentage of the cost initially deferred, and our DAC balances as of December 31, 2010 and 2009.

We may experience accelerated amortization if policies terminate earlier than projected. Because our actual experience regarding persistency and premium income has varied very little from our assumptions during the last three years, we have had minimal adjustments to our projected amortization of DAC during those years. We measure the recoverability of DAC annually by performing gross premium valuations. Our testing indicates that our DAC is recoverable. In October 2010, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU), now included in Accounting Standards Codification 944 “Financial Services — Insurance,” which is intended to address diversity in practice regarding the interpretation of which costs relating to the acquisition of new or renewal insurance contracts qualify as deferred acquisition costs. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2011, and permit retrospective application. The guidance in this update will result in a decrease in the opening balance of our retained earnings if we choose retrospective application on adoption and will result in a decrease in the level of costs we defer subsequent to adoption. Given that application guidance is still evolving, we have not yet finalized the expected impact on our financial position or results of operations. 26 4356_2010AR_Fin_ALL.indd 26 4/4/11 3:05 PM Unum 2010 Annual Report Valuation of Investments All of our fixed maturity securities are classified as available-for-sale and are reported at fair value. Our derivative financial instruments, including certain derivative instruments embedded in other contracts, are reported as either assets or liabilities and measured at fair value. We hold an immaterial amount of equity securities, which are also reported at fair value. Definition of Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and, therefore, represents an exit price, not an entry price. The exit price objective applies regardless of a reporting entity’s intent and/or ability to sell the asset or transfer the liability at the measurement date. The degree of judgment utilized in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Financial instruments with readily available active quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and less judgment utilized in measuring fair value. An active market for a financial instrument is a market in which transactions for an asset or a similar asset occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value and should be used to measure fair value whenever available. Conversely, financial instruments rarely traded or not quoted have less observability and are measured at fair value using valuation techniques that require more judgment. Pricing observability is generally impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction, and overall market conditions. Valuation Techniques Valuation techniques used for assets and liabilities accounted for at fair value are generally categorized into three types: 1. The market approach uses prices and other relevant information from market transactions involving identical or comparable assets or liabilities. Valuation techniques consistent with the market approach often use market multiples derived from a set of comparables or matrix pricing. Market multiples might lie in ranges with a different multiple for each comparable. The selection of where within the range the appropriate multiple falls requires judgment, considering both quantitative and qualitative factors specific to the measurement. Matrix pricing is a mathematical technique used principally to value certain securities without relying exclusively on quoted prices for the specific securities but comparing the securities to benchmark or comparable securities. 2. The income approach converts future amounts, such as cash flows or earnings, to a single present amount, or a discounted amount. Income approach techniques rely on current market expectations of future amounts. Examples of income approach valuation techniques include present value techniques, option-pricing models that incorporate present value techniques, and the multi-period excess earnings method. 3. The cost approach is based upon the amount that currently would be required to replace the service capacity of an asset, or the current replacement cost. That is, from the perspective of a market participant (seller), the price that would be received for the asset is determined based on the cost to a market participant (buyer) to acquire or construct a substitute asset of comparable utility. We use valuation techniques that are appropriate in the circumstances and for which sufficient data are available that can be obtained without undue cost and effort. In some cases, a single valuation technique will be appropriate (for example, when valuing an asset or liability using quoted prices in an active market for identical assets or liabilities). In other cases, multiple valuation techniques will be appropriate. If we use multiple valuation techniques to measure fair value, we evaluate and weigh the results, as appropriate, considering the reasonableness of the range indicated by those results. A fair value measurement is the point within that range that is most representative of fair value in the circumstances. The selection of the valuation method(s) to apply considers the definition of an exit price and depends on the nature of the asset or liability being valued. For assets and liabilities accounted for at fair value, we generally use valuation techniques consistent with the market approach, and to a lesser extent, the income approach. We believe the market approach valuation technique provides more observable data than the income approach, considering the type of investments we hold. Our fair value measurements could differ significantly based on the valuation technique and available inputs. When markets are less active, brokers may rely more on models with inputs based on the 4356_2010AR_Fin_ALL.indd 27 27 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 information available only to the broker. In weighing a broker quote as an input to fair value, we place less reliance on quotes that do not reflect the result of market transactions. We also consider the nature of the quote, particularly whether the quote is a binding offer. If prices in an inactive market do not reflect current prices for the same or similar assets, adjustments may be necessary to arrive at fair value. When relevant market data is unavailable, which may be the case during periods of market uncertainty, the income approach can, in suitable circumstances, provide a more appropriate fair value. During 2010, we have applied valuation techniques on a consistent basis to similar assets and liabilities and consistent with those techniques used at year end 2009. Inputs to Valuation Techniques Inputs refer broadly to the assumptions that market participants use in pricing assets or liabilities, including assumptions about risk, for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. Inputs that may be used include the following: • Broker market maker prices and price levels • Trade Reporting and Compliance Engine (TRACE) pricing • Prices obtained from external pricing services • Benchmark yields (Treasury and interest rate swap curves) • Transactional data for new issuance and secondary trades • Security cash flows and structures • Recent issuance/supply • Sector and issuer level spreads • Security credit ratings/maturity/capital structure/optionality • Corporate actions • Underlying collateral • Prepayment speeds/loan performance/delinquencies/weighted average life/seasoning • Public covenants • Comparative bond analysis • Derivative spreads • Relevant reports issued by analysts and rating agencies • Audited financial statements We review all prices obtained to ensure they are consistent with a variety of observable market inputs and to verify the validity of a security’s price. The overall valuation process for determining fair values may include adjustments to valuations obtained from our pricing sources when they do not represent a valid exit price. These adjustments may be made when, in our judgment and considering our knowledge of the financial conditions and industry in which the issuer operates, certain features of the financial instrument require that an adjustment be made to the value originally obtained from our pricing sources. These features may include the complexity of the financial instrument, the market in which the financial instrument is traded, counterparty credit risk, credit structure, concentration, or liquidity. Additionally, an adjustment to the price derived from a model typically reflects our judgment of the inputs that other participants in the market for the financial instrument being measured at fair value would consider in pricing that same financial instrument. The parameters and inputs used to validate a price on a security may be adjusted for assumptions about risk and current market conditions on a quarter to quarter basis, as certain features may be more significant drivers of valuation at the time of pricing. Changes to inputs in valuations are not changes to valuation methodologies; rather, the inputs are modified to reflect direct or indirect impacts on asset classes from changes in market conditions. 28 4356_2010AR_Fin_ALL.indd 28 4/4/11 3:05 PM Unum 2010 Annual Report Fair values for derivatives other than embedded derivatives in modified coinsurance arrangements are based on market quotes or pricing models and represent the net amount of cash we would have paid or received if the contracts had been settled or closed as of the last day of the period. We analyze credit default swap spreads relative to the average credit spread embedded within the London Interbank Offered Rate (LIBOR) setting syndicate in determining the effect of credit risk on our derivatives’ fair values. If counterparty credit risk for a derivative asset is determined to be material and is not adequately reflected in the LIBOR-based fair value obtained from our pricing sources, we adjust the valuations obtained from our pricing sources. In regard to our own credit risk component, we adjust the valuation of derivative liabilities wherein the counterparty is exposed to our credit risk when the LIBOR-based valuation of our derivatives obtained from pricing sources does not effectively include an adequate credit component for our own credit risk. Fair values for our embedded derivative in a modified coinsurance arrangement are estimated using internal pricing models and represent the hypothetical value of the duration mismatch of assets and liabilities, interest rate risk, and third party credit risk embedded in the modified coinsurance arrangement. Certain of our investments do not have readily determinable market prices and/or observable inputs or may at times be affected by the lack of market liquidity. For these securities, we use internally prepared valuations combining matrix pricing with vendor purchased software programs, including valuations based on estimates of future profitability, to estimate the fair value. Additionally, we may obtain prices from independent third-party brokers to aid in establishing valuations for certain of these securities. Key assumptions used by us to determine fair value for these securities include risk free interest rates, risk premiums, performance of underlying collateral (if any), and other factors involving significant assumptions which may or may not reflect those of an active market. As of December 31, 2010, the key assumptions we generally used to estimate the fair value of these types of securities included those listed below. Where appropriate, we have noted the assumption used for the prior period as well as the reason for the change. • Risk free interest rates of 2.01 percent for five-year maturities to 4.33 percent for 30-year maturities were derived from the current yield curve for U.S. Treasury Bonds with similar maturities. This compares to interest rates of 2.68 percent for five-year maturities to 4.64 percent for 30-year maturities used at December 31, 2009. • Current Baa corporate bond spreads ranging from 1.31 percent to 1.95 percent plus an additional 20 basis points were added to the risk free rate to reflect the lack of liquidity. We used spreads ranging from 1.60 percent to 2.00 percent plus an additional 20 basis points at December 31, 2009. The changes were based on observable market spreads. Newly issued private placement securities have historically offered yield premiums of 20 basis points over comparable newly issued public securities. • An additional five basis points were added to the risk free rates for foreign investments, consistent with December 31, 2009. • Additional basis points were added as deemed appropriate for certain industries and for individual securities in certain industries that are considered to be of greater risk. Increasing the 20 basis points added to the risk free rate for lack of liquidity by one basis point, increasing the five basis points added to the risk free rates for foreign investments by one basis point, and increasing the additional basis points added to each industry considered to be of greater risk by one basis point would have decreased the December 31, 2010 fair value of these types of securities by approximately $0.5 million. We believe this range of variability is appropriate, and historically the inputs noted have generally not deviated outside the range provided. We regularly test the validity of the fair values determined by our valuation techniques by comparing the prices of assets sold to the fair values reported for the assets in the immediately preceding reporting period. Historically, our realized gains or losses on dispositions of investments have not varied significantly from amounts estimated under the valuation methodologies described above, which, combined with the results of our testing, indicates to us that our pricing methodologies are appropriate. At December 31, 2010, approximately 13.5 percent of our fixed maturity securities were valued using active trades from TRACE pricing or broker market maker prices for which there was current market activity in that specific security (comparable to receiving one binding quote). The prices obtained were not adjusted, and the assets were classified as Level 1, the highest category of the three-level fair value hierarchy classification wherein inputs are unadjusted and represent quoted prices in active markets for identical assets or liabilities. The remaining 86.5 percent of our fixed maturity securities were valued based on non-binding quotes or other observable or unobservable inputs, as discussed below. 4356_2010AR_Fin_ALL.indd 29 29 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 • Approximately 69.7 percent of our fixed maturity securities were valued based on prices from pricing services that generally use observable inputs such as prices for securities or comparable securities in active markets in their valuation techniques. These assets were classified as Level 2. Level 2 assets or liabilities are those valued using inputs (other than prices included in Level 1) that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. • Approximately 5.3 percent of our fixed maturity securities were valued based on one or more non-binding broker price levels, if validated by observable market data, or on TRACE prices for identical or similar assets absent current market activity. When only one price is available, it is used if observable inputs and analysis confirms that it is appropriate. These assets, for which we were able to validate the price using other observable market data, were classified as Level 2. • Approximately 11.5 percent of our fixed maturity securities were valued based on prices of comparable securities, matrix pricing, market models, and/or internal models or were valued based on non-binding quotes with no other observable market data. These assets were classified as either Level 2 or Level 3, with the categorization dependent on whether there was other observable market data. Level 3 is the lowest category of the fair value hierarchy and reflects the judgment of management regarding what market participants would use in pricing assets or liabilities at the measurement date. Financial assets and liabilities categorized as Level 3 are generally those that are valued using unobservable inputs to extrapolate an estimated fair value. We consider transactions in inactive or disorderly markets to be less representative of fair value. We use all available observable inputs when measuring fair value, but when significant other unobservable inputs and adjustments are necessary, we classify these assets or liabilities as Level 3. As of December 31, 2010, approximately 13.5 percent of our fixed maturity securities were categorized as Level 1, 83.9 percent as Level 2, and 2.6 percent as Level 3. During 2010, we transferred $565.1 million of fixed maturity securities into Level 3 and $503.8 million of fixed maturity securities out of Level 3. The transfers between levels resulted primarily from a change in observability of three inputs used to determine fair values of the securities transferred: (1) transactional data for new issuance and secondary trades, (2) broker/dealer quotes and pricing, primarily related to changes in the level of activity in the market and whether the market was considered orderly, and (3) comparable bond metrics from which to perform an analysis. For fair value measurements of financial instruments that were transferred either into or out of Level 3, we reflect the transfers using the fair value at the beginning of the period. We believe this allows for greater transparency as all changes in fair value that arise during the reporting period of the transfer are disclosed as a component of our Level 3 reconciliation as shown in Note 2 of the “Notes to Consolidated Financial Statements.” Other-than-Temporary Impairment Analysis for Investments In determining when a decline in fair value below amortized cost of a fixed maturity security is other than temporary, we evaluate the following factors: • Whether we expect to recover the entire amortized cost basis of the security. • Whether we intend to sell the security or will be required to sell the security before the recovery of its amortized cost basis. • Whether the security is current as to principal and interest payments. • The significance of the decline in value. • The time period during which there has been a significant decline in value. • Current and future business prospects and trends of earnings. • The valuation of the security’s underlying collateral. • Relevant industry conditions and trends relative to their historical cycles. • Market conditions. • Rating agency and governmental actions. • Bid and offering prices and the level of trading activity. • Adverse changes in estimated cash flows for securitized investments. • Changes in fair value subsequent to the balance sheet date. • Any other key measures for the related security. 30 4356_2010AR_Fin_ALL.indd 30 4/4/11 3:05 PM Unum 2010 Annual Report We evaluate available information, including the factors noted above, both positive and negative, in reaching our conclusions. In particular, we also consider the strength of the issuer’s balance sheet, its debt obligations and near term funding requirements, cash flow and liquidity, the profitability of its core businesses, the availability of marketable assets which could be sold to increase liquidity, its industry fundamentals and regulatory environment, and its access to capital markets. Although all available and applicable factors are considered in our analysis, our expectation of recovering the entire amortized cost basis of the security, whether we intend to sell the security, whether it is more likely than not we will be required to sell the security before recovery of its amortized cost, and whether the security is current on principal and interest payments are the most critical factors in determining whether impairments are other than temporary. The significance of the decline in value and the length of time during which there has been a significant decline are also important factors, but we generally do not record an impairment loss based solely on these two factors, since often other more relevant factors will impact our evaluation of a security. While determining other-than-temporary impairments is a judgmental area, we utilize a formal, well-defined, and disciplined process to monitor and evaluate our fixed income investment portfolio, supported by issuer specific research and documentation as of the end of each period. The process results in a thorough evaluation of problem investments and the recording of losses on a timely basis for investments determined to have an other-than-temporary impairment. If we determine that the decline in value of an investment is other than temporary, the investment is written down to fair value, and an impairment loss is recognized in the current period, either in earnings or in both earnings and other comprehensive income, as applicable. For those fixed maturity securities with an unrealized loss for which we have not recognized an other-than-temporary impairment, we believe we will recover the entire amortized cost, we do not intend to sell the security, and we do not believe it is more likely than not we will be required to sell the security before recovery of its amortized cost. There have been no defaults in the repayment obligations of any securities for which we have not recorded an other-than-temporary impairment. Other-than-temporary impairment losses on fixed maturity securities which we intend to sell or more likely than not will be required to sell before recovery in value are recognized in earnings and equal the entire difference between the security’s amortized cost basis and its fair value. For securities which we do not intend to sell and it is not more likely than not that we will be required to sell before recovery in value, other-than-temporary impairment losses recognized in earnings generally represent the difference between the amortized cost of the security and the present value of our best estimate of cash flows expected to be collected, discounted using the effective interest rate implicit in the security at the date of acquisition. The determination of cash flows is inherently subjective, and methodologies may vary depending on the circumstances specific to the security. The timing and amount of our cash flow estimates are developed using historical and forecast financial information from the issuer, including its current and projected liquidity position. We also consider industry analyst reports and forecasts, sector credit ratings, future business prospects and earnings trends, issuer refinancing capabilities, actual and/or potential asset sales by the issuer, and other data relevant to the collectibility of the contractual cash flows of the security. We take into account the probability of default, expected recoveries, third party guarantees, quality of collateral, and where our debt security ranks in terms of subordination. We may use the estimated fair value of collateral as a proxy for the present value of cash flows if we believe the security is dependent on the liquidation of collateral for recovery of our investment. For fixed maturity securities for which we have recognized an other-than-temporary impairment loss through earnings, if through subsequent evaluation there is a significant increase in expected cash flows, the difference between the new amortized cost basis and the cash flows expected to be collected is accreted as net investment income. We use a comprehensive rating system to evaluate the investment and credit risk of our mortgage loans and to identify specific properties for inspection and reevaluation. Mortgage loans are considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. We establish an allowance for probable losses on mortgage loans based on a review of individual loans, considering the value of the underlying collateral. Mortgage loans are not reported at fair value in our consolidated balance sheets unless the mortgage loan is considered impaired, in which case the impairment is recognized as a realized investment loss in our consolidated statements of income. There are a number of significant risks inherent in the process of monitoring our investments for impairments and determining when and if an impairment is other than temporary. These risks and uncertainties include the following possibilities: 4356_2010AR_Fin_ALL.indd 31 31 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 • The assessment of a borrower’s ability to meet its contractual obligations will change. • The economic outlook, either domestic or foreign, may be less favorable or may have a more significant impact on the borrower than anticipated, and as such, the investment may not recover in value. • New information may become available concerning the security, such as disclosure of accounting irregularities, fraud, or corporate governance issues. • Significant changes in credit spreads may occur in the related industry. • Significant increases in interest rates may occur and may not return to levels similar to when securities were initially purchased. • Adverse rating agency actions may occur. Pension and Postretirement Benefit Plans We sponsor several defined benefit pension and other postretirement benefit (OPEB) plans for our employees, including non-qualified pension plans. The U.S. pension plans comprise the majority of our total benefit obligation and pension expense. Our U.K. operation maintains a separate defined benefit plan for eligible employees. The U.K. defined benefit pension plan was closed to new entrants on December 31, 2002. Our net periodic benefit costs and the value of our benefit obligations for these plans are determined based on a set of economic and demographic assumptions that represent our best estimate of future expected experience. Major assumptions used in accounting for these plans include the expected discount (interest) rate and the long-term rate of return on plan assets. We also use, as applicable, expected increases in compensation levels and a weighted average annual rate of increase in the per capita cost of covered benefits, which reflects a health care cost trend rate, and the U.K. pension plan also uses expected cost of living increases to plan benefits. The assumptions chosen for our pension and OPEB plans are reviewed annually, and we use a December 31 measurement date for each of our plans. The discount rate assumptions and expected long-term rate of return assumptions have the most significant effect on our net periodic benefit costs associated with these plans. In addition to the effect of changes in our assumptions, the net periodic cost or benefit obligation under our pension and OPEB plans may change due to factors such as actual experience being different from our assumptions, special benefits to terminated employees, or changes in benefits provided under the plans. Discount Rate Assumptions The discount rate is an interest assumption used to convert the benefit payment stream to a present value. We set the discount rate assumption at the measurement date for each of our retirement-related benefit plans to reflect the yield of a portfolio of high quality fixed income debt instruments matched against the timing and amounts of projected future benefits. A lower discount rate increases the present value of benefit obligations and increases our costs. The discount rate we used to determine our 2011 and 2010 net periodic benefit costs for our U.S. pension plans was 5.80 percent and 6.40 percent, respectively. The discount rate used for the net periodic benefit costs for 2011 and 2010 for our U.K. pension plan was 5.60 percent and 5.70 percent, respectively. The discount rate used in the net periodic benefit cost for our OPEB plan for 2011 and 2010 was 5.60 percent and 5.90 percent, respectively. Reducing the discount rate assumption by 50 basis points would have resulted in an increase in our 2010 pension expense of approximately $12.9 million, before tax, and an increase in our benefit obligation of approximately $139.8 million as of December 31, 2010, resulting in an after-tax decrease in stockholders’ equity of approximately $92.1 million as of December 31, 2010. A 50 basis point reduction in the discount rate assumption would not change our annual OPEB costs. Increasing the discount rate assumption by 50 basis points would have resulted in a decrease in our 2010 pension expense of approximately $11.9 million, before tax, and a decrease in our benefit obligation of approximately $123.8 million as of December 31, 2010, resulting in an after-tax increase in stockholders’ equity of approximately $81.6 million as of December 31, 2010. A 50 basis point increase in the discount rate assumption would not change our annual OPEB costs. 32 4356_2010AR_Fin_ALL.indd 32 4/4/11 3:05 PM Unum 2010 Annual Report Long-term Rate of Return Assumptions The long-term rate of return assumption is the best estimate of the average annual assumed return that will be produced from the pension trust assets until current benefits are paid. The U.S. pension plans use a compound interest method in computing the rate of return on their pension plan assets. The investment portfolio for our U.S. pension plans contain a diversified blend of domestic and international large cap, mid cap, and small cap equity securities, U.S. government and agency and corporate fixed income securities, private equity funds of funds, and hedge funds of funds. Assets for our U.K. pension plan are invested in pooled funds, including a diversified growth fund, which invests in assets such as global equities, hedge funds, commodities, below-investment-grade fixed income securities, and currencies, as well as a fixed-interest U.K. corporate bond fund and an index-linked U.K. government bond fund. Assets for our OPEB plan are invested primarily in life insurance contracts. We believe our investment portfolios are well diversified by asset class and sector, with no potential risk concentrations in any one category. Our expectations for the future investment returns of the asset categories are based on a combination of historical market performance and evaluations of investment forecasts obtained from external consultants and economists, and based on current market yields. For the U.S. pension plans, the methodology underlying the return assumption included the various elements of the expected return for each asset class such as long-term rates of return, volatility of returns, and the correlation of returns between various asset classes. The expected return for the total portfolio is calculated based on the plan’s current asset allocation. Investment risk is measured and monitored on an ongoing basis through annual liability measurements, periodic asset/liability studies, and quarterly investment portfolio reviews. Risk tolerance is established through consideration of plan liabilities, plan funded status, and corporate financial condition. The long-term rate of return on assets used in the net periodic pension costs for our U.S. qualified defined benefit pension plan for 2011 and 2010 was 7.50 percent for both years. The long-term rate of return on asset assumption used for 2011 and 2010 for our U.K. pension plan was 6.70 percent and 6.90 percent, respectively, and for our OPEB plan, 5.75 percent for both years. The actual rate of return on plan assets is determined based on the fair value of the plan assets at the beginning and the end of the period, adjusted for contributions and benefit payments. Changing the expected long-term rate of return on the plan assets by +/-50 basis points would have changed our 2010 pension plan expense by approximately $5.8 million before tax, but our OPEB plan expense would not change. A lower rate of return on plan assets increases our expense. Benefit Obligation and Fair Value of Plan Assets The market-related value equals the fair value of assets, determined as of the measurement date. The expected return on assets fully recognizes all asset gains and losses, including changes in fair value, through the measurement date. During 2010, the fair value of our plan assets in our U.S. qualified defined benefit pension plan increased $291.1 million, or approximately 32.8 percent. The fair value of plan assets for our U.K. pension plan increased £13.2 million, or approximately 13.3 percent, during 2010. Although the effect of these increases had no impact on our 2010 net periodic pension costs, the favorable rate of return on plan assets in 2010 has a favorable impact on our net periodic pension costs for 2011. We expect that our 2011 pension costs will be generally consistent with the level of our pension costs in 2010, however, given the decrease in the discount rate. We believe our assumptions appropriately reflect the impact of the current economic environment. Our pension and OPEB plans have an aggregate unrecognized net actuarial loss of $512.4 million and an unrecognized prior service credit of $7.6 million, which together represent the cumulative liability and asset gains and losses as well as the portion of prior service credits that have not been recognized in pension expense. As of December 31, 2010, the unrecognized net loss for these two items combined was approximately $504.8 million. The unrecognized gains or losses are amortized as a component of the net benefit cost. Our 2010, 2009, and 2008, pension and OPEB expense includes $29.1 million, $40.2 million, and $10.6 million, respectively, of amortization of the unrecognized net actuarial gain (loss) and prior service credit (cost). The lower amortization in 2010 resulted primarily from the decrease in the unrecognized net actuarial loss due to the favorable rate of return on plan assets for our U.S. pension plans. The unrecognized net actuarial loss for our pension plans, which is $513.8 million at December 31, 2010, will be amortized over the average future working life of pension plan participants, currently estimated at 11 years for U.S. participants and 15 years for U.K. participants, to the extent that it exceeds the 10 percent corridor, as 4356_2010AR_Fin_ALL.indd 33 33 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 described below. The unrecognized net actuarial gain of $1.4 million for our OPEB plan will be amortized over the average future working life of OPEB plan participants, currently estimated at 8 years, to the extent the loss is outside of a corridor established in accordance with GAAP. The corridor for the pension and OPEB plans is established based on the greater of 10 percent of the plan assets or 10 percent of the benefit obligation. At December 31, 2010, none of the actuarial gain was outside of the corridor for the OPEB plan. The fair value of plan assets in our U.S. qualified defined benefit pension plan was $1,179.6 million at December 31, 2010, compared to $888.5 million at December 31, 2009. This increase in fair value of plan assets and the effect of the plan contributions during 2010 lowered our year end deficit funding level in the plan to $64.0 million as of December 31, 2010, compared to a deficit of $143.3 million as of December 31, 2009. The fair value of plan assets in our OPEB plan was $11.9 million at both December 31, 2010 and 2009. These assets represent life insurance contracts to fund the life insurance benefit portion of our OPEB plan. Our OPEB plan represents a non-vested, non-guaranteed obligation, and current regulations do not require specific funding levels for these benefits, which are comprised of retiree life, medical, and dental benefits. It is our practice to use general assets to pay medical and dental claims as they come due in lieu of utilizing plan assets for the medical and dental benefit portions of our OPEB plan. We expect to continue to receive subsidies under the Medicare Prescription Drug, Improvement and Modernization Act of 2003, based on current law, to partially offset these payments. The expected subsidy included in our consolidated balance sheets is immaterial. Our expected return on plan assets and discount rate discussed above will not affect the cash contributions we are required to make to our U.S. pension and OPEB plans because we have met all minimum funding requirements set forth by ERISA. We had no regulatory contribution requirements for 2010 and 2009; however, we elected to make voluntary contributions of $167.0 million and $70.0 million, respectively, to our U.S. qualified defined benefit pension plan. We do not anticipate making any additional contributions during 2011. During 2006, the U.S. federal government enacted the Pension Protection Act of 2006 which requires companies to fully fund defined benefit pension plans over a seven year period. We have evaluated this requirement and have made estimates of amounts to be funded in the future. Based on this assessment, we do not believe that the funding requirements of the Pension Protection Act will cause a material adverse effect on our liquidity. The fair value of plan assets for our U.K. pension plan was £112.7 million at December 31, 2010, compared to £99.5 million at December 31, 2009. The U.K. pension plan has a surplus of £14.8 million at December 31, 2010, compared to a deficit of £7.8 million at December 31, 2009. We contribute to the plan in accordance with a schedule of contributions which requires that we contribute to the plan at the rate of at least 15.0 percent of total employee salaries (including employees who are not members of the defined benefit plan), less contributions to our defined contribution plan, sufficient to meet the minimum funding requirement under U.K. legislation. During 2010 and 2009, we made required contributions of £3.2 million and £3.5 million, respectively. We anticipate that we will make contributions during 2011 of approximately £3.2 million. See Note 8 of the “Notes to Consolidated Financial Statements” for further discussion. Income Taxes We record a valuation allowance to reduce deferred tax assets to the amount that is more likely than not to be realized. Our valuation allowance relates primarily to assets for foreign net operating loss carryforwards and assets for our basis in certain of our foreign subsidiaries that are not likely to be realized in the future based on our expectations using currently available evidence. In evaluating the ability to recover deferred tax assets, we have considered all available positive and negative evidence including past operating results, the existence of cumulative losses in the most recent years, forecasted earnings, future taxable income, and prudent and feasible tax planning strategies. In the event we determine that we most likely would not be able to realize all or part of our deferred tax assets in the future, an increase to the valuation allowance would be charged to earnings in the period such determination is made. Likewise, if it is later determined that it is more likely than not that those deferred tax assets would be realized, the previously provided valuation allowance would be reversed. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws in a multitude of jurisdictions, both domestic and foreign. The amount of income taxes we pay is subject to ongoing audits in various jurisdictions, and a material assessment by a governing tax authority could affect profitability. 34 4356_2010AR_Fin_ALL.indd 34 4/4/11 3:05 PM Unum 2010 Annual Report GAAP prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in income tax returns. The evaluation of a tax position is a two step process. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination based on the technical merits of the position. The second step is to measure a position that satisfies the recognition threshold at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more likely than not threshold but that now satisfy the recognition threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more likely than not recognition threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. If a previously recognized tax position is settled for an amount that is different from the amount initially measured, the difference will be recognized as a tax benefit or expense in the period the settlement is effective. We believe that tax positions have been reflected in our financial statements at appropriate amounts in conformity with GAAP. See Note 6 of the “Notes to Consolidated Financial Statements” for further discussion. Contingent Liabilities On a quarterly basis, we review relevant information with respect to litigation and contingencies to be reflected in our consolidated financial statements. An estimated loss is accrued when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. It is possible that our results of operations or cash flows in a particular period could be materially affected by an ultimate unfavorable outcome of pending litigation or regulatory matters depending, in part, on our results of operations or cash flows for the particular period. See Note 13 of the “Notes to Consolidated Financial Statements” for further discussion.

The functional currency of our U.K. operations is the British pound sterling. In periods when the pound weakens, translating pounds into dollars decreases current period results relative to the prior period. In periods when the pound strengthens, translating pounds into dollars increases current period results in relation to the prior period. Our weighted average pound/dollar exchange rate was 1.543, 1.554, and 1.871 for the years ended 2010, 2009, and 2008, respectively. While the impact of the difference in exchange rates year over year on the comparability of our consolidated results was not material for 2010 and 2009, our operating revenue and operating income by segment would have been lower in 2008 by approximately $183.1 million and $58.8 million, respectively, if the results for our U.K. operations had been translated at a constant exchange rate of 1.543, the rate for 2010. However, it is important to distinguish between translating and converting foreign currency. Except for a limited number of transactions, we do not actually convert pounds into dollars. As a result, we view foreign currency translation as a financial reporting item and not a reflection of operations or profitability in the U.K. Consolidated premium income for both 2010 and 2009 includes premium growth, relative to the preceding years, for our Unum US long-term care and voluntary benefits lines of business as well as for Colonial Life. Unum US group life and accidental death and dismemberment experienced premium growth in 2010 relative to 2009. Our Unum US group disability line of business experienced year over year declines in premium income during 2010 and 2009 relative to prior years due primarily to the ongoing high levels of unemployment and the competitive environment which impact sales growth and premium growth from existing customers. In particular, premium growth from existing customers continues to be unfavorably impacted by lower salary growth and lower growth in the number of employees covered under an existing policy. Premium income for Unum US individual disability — recently issued declined year over year primarily due to lower sales. Unum UK premium income, in local currency, decreased in both 2010 and 2009 relative to preceding years due primarily to lower premium growth from existing customers, similar to Unum US, and pricing actions due to the competitive U.K. market. Premium income in the Individual Disability — Closed Block segment, which is a closed block of business, continued its expected decline. Net investment income was higher in 2010 relative to 2009 due primarily to continued growth in the level of invested assets and higher bond call premiums. We also received higher interest income during 2010 on bonds for which interest income is linked to a U.K. inflation index. These index-linked bonds match the claim reserves associated with certain of our Unum UK group policies that provide for inflation-linked increases in benefits, with the increase or decrease in investment income on these bonds generally offset by an increase or decrease in reserves. Net investment income was lower in 2009 relative to 2008 due to the weaker pound in 2009 compared to 2008, lower interest income on the inflation index-linked bonds, and lower bond call premiums and consent fees, somewhat offset by the continued growth in the level of invested assets. We recognized in earnings a net realized investment gain of $24.7 million in 2010 compared to a gain of $11.7 million in 2009 and a loss of $465.9 million in 2008. Included in these amounts were other-than-temporary impairment losses on fixed maturity securities of $15.9 million in 2010, $215.5 million in 2009, and $151.1 million in 2008. Of these amounts, all were recognized in earnings other than a loss of $3.7 million in 2009 which was recognized in other comprehensive income. Also recognized in earnings through realized investment gains and losses was the change in the fair value of an embedded derivative in a modified coinsurance arrangement. During 2010 and 2009, changes in the fair value of this embedded derivative resulted in realized gains of $21.1 million and $243.1 million, respectively, compared to a realized loss of $291.7 million in 2008. Gains and losses on this embedded derivative result primarily from a change in credit spreads in the overall investment market. 36 4356_2010AR_Fin_ALL.indd 36 4/4/11 3:05 PM Unum 2010 Annual Report The benefit ratio was 85.5 percent in 2010 compared to 84.2 percent in 2009 and 85.1 percent in 2008, with generally consistent overall risk results in Unum US but higher benefit ratios in Unum UK and Colonial Life during 2010 relative to 2009. Risk results in 2009 improved in each of our business segments compared to 2008. Further discussion of our line of business risk results and claims management performance for each of our segments is included in “Segment Results” as follows. Interest and debt expense for 2010 was higher than in 2009 due to higher levels of outstanding debt, partially offset by lower rates of interest on our floating rate debt. Interest and debt expense for 2009 was lower than 2008 due primarily to lower average levels of outstanding debt and lower rates of interest on our floating rate debt. See “Debt” contained herein for additional information. The deferral of acquisition costs increased in 2010 relative to 2009, with continued growth in certain of our product lines and the associated increase in deferrable expenses more than offsetting the lower level of deferrable costs in product lines with lower growth. The deferral of acquisition costs in 2009 was generally consistent with the level of 2008. The amortization of acquisition costs in 2010 and 2009 was slightly higher than the preceding years due to the continued increase in the level of deferred acquisition costs as well as an acceleration of amortization resulting from lower persistency for certain issue years in the Unum US supplemental and voluntary lines. Although the 2010 rate of persistency for the overall block of business within each of the supplemental and voluntary lines was favorable to 2009, the persistency for certain individual issue years was less than expected and required additional amortization of deferred acquisition costs. Other expenses decreased in 2010 compared to 2009, primarily due to a decline in our pension costs. Other expenses, as reported, decreased slightly in 2009 relative to 2008. However, if the effect of the lower exchange rate for translating Unum UK’s expenses is excluded, other expenses increased in 2009 due primarily to an increase in our pension costs in 2009 relative to 2008. The income tax rate in the U.K. will be reduced from 28 percent to 27 percent in April 2011. In accordance with GAAP, we are required to adjust deferred tax assets and liabilities through income on the date of enactment of a rate change, which occurred during the third quarter of 2010. Our income tax expense for 2010 includes a reduction of $2.7 million which was recorded in the third quarter of 2010 to reflect the impact of the rate change on our net deferred tax liability related to our U.K. operations. Our income tax rate for 2010 was also lower relative to preceding years due to tax benefits recognized as a result of our increased level of investments in low-income housing tax credit partnerships. In March 2010, legislation related to health care reform was signed into law. Among other things, the new legislation reduces the tax benefits available to an employer that receives a postretirement prescription drug coverage subsidy from the federal government under the Medicare Prescription Drug, Improvement and Modernization Act of 2003. Under the new legislation, to the extent our future postretirement prescription drug coverage expenses are reimbursed under the subsidy program, the expenses covered by the subsidy will no longer be tax deductible after 2012. Employers that receive the subsidy must recognize the deferred tax effects relating to the future postretirement prescription drug coverage in the period the legislation was enacted. Our income tax expense for 2010 includes a non-cash tax charge of $10.2 million which was recorded in the first quarter of 2010 to reflect the impact of the tax law change. 4356_2010AR_Fin_ALL.indd 37 37 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Consolidated Sales Results (in millions of dollars) Unum US Fully Insured Products Year Ended December 31 2010 % Change 2009 % Change 2008 $ 669.4 (5.6)% $ 709.2 1.1% $ 701.5 Administrative Services Only (ASO) Products 6.3 (18.2) Total Unum US Unum UK Colonial Life Individual Disability — Closed Block 675.7 119.2 358.8 0.8 (5.7) (3.2) 4.4 (46.7) 7.7 716.9 123.2 343.8 1.5 6.9 1.2 23.8 1.1 (37.5) 7.2 708.7 99.5 340.2 2.4 Consolidated $1,154.5 (2.6) $1,185.4 3.0 $1,150.8 Sales results shown in the preceding chart generally represent the annualized premium or annualized fee income on new sales which we expect to receive and report as premium income or fee income during the next 12 months following or beginning in the initial quarter in which the sale is reported, depending on the effective date of the new sale. Sales do not correspond to premium income or fee income reported as revenue in accordance with GAAP. This is because new annualized sales premiums reflect current sales performance and what we expect to recognize as premium or fee income over a 12 month period, while premium income and fee income reported in our financial statements are reported on an “as earned” basis rather than an annualized basis and also include renewals and persistency of in-force policies written in prior years as well as current new sales. Premiums for fully insured products are reported as premium income. Fees for administrative services only (ASO) products are included in other income. Sales, persistency of the existing block of business, and the effectiveness of a renewal program are indicators of growth in premium and fee income. Trends in new sales, as well as existing market share, also indicate the potential for growth in our respective markets and the level of market acceptance of price changes and new product offerings. Sales results may fluctuate significantly due to case size and timing of sales submissions. We have experienced lower sales growth in some of our product lines during both 2010 and 2009, particularly in the expansion of sales to existing accounts, which we believe is mostly attributable to the current economic environment. We expect this unfavorable pattern may continue in the near term if current economic conditions persist. See “Segment Results” as follows for additional discussion of sales by segment. 38 4356_2010AR_Fin_ALL.indd 38 4/4/11 3:05 PM Unum 2010 Annual Report Reconciliation of Non-GAAP Financial Measures We analyze our performance using non-GAAP financial measures which exclude certain items and the related tax thereon from net income. We believe operating income or loss excluding realized investment gains and losses, which may be recurring, and the 2010 tax charge to reflect the impact of the tax law change, as previously discussed, is a better performance measure and a better indicator of the profitability and underlying trends in our business. In the following segment financial data and discussions of segment results, “operating revenue” excludes net realized investment gains and losses. “Operating income” or “operating loss” excludes net realized investment gains and losses and income tax. These are considered non-GAAP financial measures. A non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP financial measures of “operating revenue,” “operating income” or “operating loss,” and “after-tax operating income” differ from revenue, income (loss) before income tax, and net income as presented in our consolidated operating results and in income statements prepared in accordance with GAAP due to the exclusion of before-tax realized investment gains and losses and certain tax items. We measure performance excluding realized investment gains and losses and certain tax items because we believe that this performance measure is a better indicator of the ongoing businesses and the underlying trends in the businesses. Our investment focus is on investment income to support our insurance liabilities as opposed to the generation of realized investment gains and losses, and a long- term focus is necessary to maintain profitability over the life of the business. Realized investment gains and losses depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our segments. However, income or loss excluding realized investment gains and losses and certain tax items does not replace net income or net loss as a measure of overall profitability. We may experience realized investment losses, which will affect future earnings levels since our underlying business is long-term in nature and we need to earn the assumed interest rates in our liabilities. A reconciliation of operating revenue by segment to revenue, operating income by segment to net income, and after-tax operating income to net income is as follows: (in millions of dollars) Operating Revenue by Segment Net Realized Investment Gain (Loss) Revenue Operating Income by Segment Net Realized Investment Gain (Loss) Income Tax Net Income After-tax Operating Income Net Realized Investment Gain (Loss) Income Tax (Benefit on Net Realized Investment Gain (Loss) Tax Charge Net Income *Assuming dilution Year Ended December 31 2010 2009 2008 $10,168.5 $10,079.3 $10,448.2 24.7 11.7 (465.9) $10,193.2 $10,091.0 $ 1,306.6 $ 1,280.6 24.7 445.2 11.7 439.7 $ 9,982.3 $ 1,289.9 (465.9) 270.8 $ 886.1 $ 852.6 $ 553.2 Year Ended December 31 2010 2009 2008 (in millions) per share* (in millions) per share* (in millions) per share* $880.6 24.7 $ 2.69 0.08 $852.4 11.7 9.0 (10.2) 0.03 (0.03) 11.5 — $2.57 0.04 0.04 — $ 857.3 (465.9) $ 2.51 (1.36) (161.8) — (0.47) — $886.1 $ 2.71 $852.6 $2.57 $ 553.2 $ 1.62 4356_2010AR_Fin_ALL.indd 39 39 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Segment Results Our reporting segments are comprised of the following: Unum US, Unum UK, Colonial Life, Individual Disability — Closed Block, and Corporate and Other. Financial information for each of the reporting segments is as follows. Unum US Segment The Unum US segment includes group long-term and short-term disability insurance, group life and accidental death and dismemberment products, and supplemental and voluntary lines of business. The supplemental and voluntary lines of business are comprised of recently issued disability insurance, group and individual long-term care insurance, and voluntary benefits products. Unum US Operating Results Shown below are financial results for the Unum US segment.

Sales in our group core market segment, which we define for Unum US as employee groups with fewer than 2,000 lives, decreased 8.3 percent in 2010 compared to 2009, with lower group long-term and short-term disability sales and lower group life and accidental death and dismemberment sales. The number of new accounts added in our group core market segment during 2010 was 3.0 percent lower than the number of new accounts added during 2009. Sales in the group large case market segment decreased 19.8 percent in 2010 compared to 2009, due in part to one large case sold in the second quarter of 2009. Our 2010 sales mix was approximately 71 percent core market and 29 percent large case market, in line with our targeted market distribution mix. Sales of voluntary benefits increased 15.6 percent in 2010 relative to 2009, and the number of new accounts increased 13.3 percent. Sales in our individual disability line of business, which are primarily concentrated in the multi-life market, decreased 17.2 percent in 2010 compared to 2009. Sales of group long-term care increased 15.2 percent in 2010 compared to 2009. We continue to believe that the group core market and voluntary benefits market, which combined together are approximately 70 percent of our Unum US sales, represent significant growth opportunities. We will also seek disciplined and opportunistic growth, generally at the market growth rate, in the group large case, group long-term care, and individual disability markets. While in the short- term we expect economic trends to continue to pressure sales growth, we believe we are well-positioned for economic recovery. Year Ended December 31, 2009 Compared with Year Ended December 31, 2008 Total sales for Unum US increased 1.2 percent in 2009 compared to 2008. Sales in our group core market segment increased 7.9 percent over 2008, with higher group short-term disability and group life core market sales partially offset by a decline in group long-term disability core market sales. The number of new accounts in our core market segment increased 6.5 percent in 2009 relative to 2008. Sales in the group large case market segment increased 1.2 percent compared to 2008. Our sales mix was approximately 68 percent core market and 32 percent large case market. Sales of voluntary benefits increased by 2.1 percent, and the number of new accounts increased by 19.5 percent compared to 2008. Sales in our individual disability line of business decreased 10.9 percent compared to 2008, and sales of group long-term care decreased 30.4 percent. We discontinued selling individual long-term care during 2009. 42 4356_2010AR_Fin_ALL.indd 42 4/4/11 3:05 PM Unum 2010 Annual Report Unum US Group Disability Operating Results Shown below are financial results and key performance indicators for Unum US group disability.

In particular, premium growth from existing customers continued to be unfavorably impacted by lower salary growth and lower growth in the number of employees covered under an existing policy. Partially offsetting the unfavorable growth trend from existing customers was higher premium and case persistency for both group long-term and short-term disability compared to 2009. Premium and case persistency increased in 2010 relative to 2009 for group long- term disability in both the core and large case market segments. Premium and case persistency increased in 2010 relative to 2009 for group short-term disability in the large case market segment and was generally consistent year over year in the core market segment. Net investment income was lower in 2010 relative to 2009 due primarily to a decrease in the level of assets supporting this line of business and a decline in the level of prepayment income on mortgage-backed securities, partially offset by an increase in bond call premiums. Other income includes ASO fees of $57.6 million and $59.2 million for 2010 and 2009, respectively. The benefit ratio was lower in 2010 compared to 2009 due primarily to a higher rate of claim recoveries for group long-term disability, offset partially by an increase in claim incidence rates for both group long-term and short-term disability. Interest and debt expense related to the debt issued by Tailwind Holdings decreased in 2010 relative to 2009 due to lower rates of interest on the floating rate debt and a decrease in the amount of outstanding debt resulting from principal repayments. The deferral of acquisition costs in 2010 was lower than 2009 due to lower sales. The amortization of acquisition costs in 2010 was lower than 2009 due to a decrease in amortization related to internal replacement transactions and a declining balance in the deferred acquisition costs asset. The other expense ratio decreased slightly in 2010 relative to 2009, despite the decline in premium income, due to our continued focus on expense management. During 2009, Unum America entered into a quota share reinsurance agreement with RGA Americas Reinsurance Company, Ltd. under which Unum America ceded closed blocks of group long-term disability claims in 2009 and in 2010. The reinsurance transaction does not meet the conditions for reinsurance accounting and is therefore recorded using the deposit method of accounting. As such, there is no effect on reported premium income or benefits. The only impact on the income statement is the risk charge paid to the reinsurer. Year Ended December 31, 2009 Compared with Year Ended December 31, 2008 Premium income for group disability declined in 2009 relative to 2008, a portion of which was expected and was attributable to our pricing, renewal, and risk selection strategy. Premium income for our Unum US group business, both disability and life, was also negatively impacted by lower premium growth from existing customers due to lower salary growth and lower growth in the number of employees covered under an existing policy. Premium persistency increased relative to 2008 for group short-term disability in both the core and large case segments. Premium persistency for group long-term disability increased relative to 2008 in the core market segment but decreased in the large case segment, resulting in an overall persistency decline for group long-term disability. Case persistency declined due to a higher number of terminated cases in the smaller size case market within the core segment. These terminations did not affect premium persistency negatively to the degree they affected case persistency due to a lower average premium per terminated case. Net investment income was consistent in 2009 relative to 2008, with an increase in the level of assets offset by lower interest rates on floating rate assets. Other income included ASO fees of $59.2 million and $64.8 million for 2009 and 2008, respectively. The benefit ratio for 2009 was lower than the benefit ratio for 2008 due primarily to a higher rate of claim recoveries for group long- term disability and a decrease in the paid claim incidence rates for group short-term disability. Paid claim incidence rates for group long- term disability were higher in 2009 relative to 2008, but the average size of new claims was lower. Interest and debt expense related to the debt issued by Tailwind Holdings decreased in 2009 relative to 2008 due to lower rates of interest on the floating rate debt and a decrease in the amount of outstanding debt resulting from principal repayments. The deferral of acquisition costs increased in 2009 relative to 2008 due to a higher level of deferrable expenses partially resulting from increased group short-term disability sales. Amortization was lower in 2009 relative to 2008 due to a decrease in amortization related to internal replacement transactions. 44 4356_2010AR_Fin_ALL.indd 44 4/4/11 3:05 PM Unum 2010 Annual Report The other expense ratio increased in 2009 compared to 2008 due primarily to the decline in premium income and an increase in policy maintenance expenses associated with the change in the mix of in-force policies from the large case market to the core market segment. Included in 2008 other expenses was $4.4 million related to a 2008 broker compensation settlement agreement.

Premium and case persistency for the group life product line increased in both the core and large case market segments. Net investment income was higher in 2010 compared to 2009 due primarily to an increase in the level of assets supporting this line of business. The benefit ratio for 2010 was consistent with 2009. Commissions were higher due to an increase in supplemental payments. The deferral of acquisition costs increased in 2010 compared to 2009 due primarily to the increase in commission expense. The amortization of acquisition costs in 2010 was lower than 2009 due primarily to a decrease in amortization related to internal replacement transactions. The other expense ratio decreased in 2010 in comparison to 2009 due to our continued focus on expense management. Year Ended December 31, 2009 Compared with Year Ended December 31, 2008 Premium income for group life and accidental death and dismemberment decreased in 2009 relative to 2008, a portion of which was expected and was due to our pricing, renewal, and risk selection strategy. Consistent with the decline in premium income for group disability, premium growth for group life and accidental death and dismemberment was also negatively impacted by lower premium growth from existing customers. Premium income for accidental death and dismemberment declined in part due to a reinsurance agreement entered into, effective January 1, 2009, to cede an $8.0 million annualized premium in-force block of business. In both product lines, premium persistency improved, but case persistency declined in comparison to 2008 due to a higher number of terminated cases in the fewer than 100 lives market segment. Net investment income was consistent in 2009 relative to 2008, with an increase in the level of assets offset by lower interest rates on floating rate assets. The benefit ratio in 2009 was higher than 2008 as a result of a higher average paid claim size in group life which was only partially offset by a lower rate of paid claim incidence. The deferral of acquisition costs increased in 2009 compared to 2008 due primarily to an increase in the level of deferrable expenses resulting from the increase in sales. Amortization of deferred acquisition costs was lower in 2009 relative to 2008 due to a decrease in amortization related to internal replacement transactions. The other expense ratio increased in 2009 in comparison to 2008 due to the decline in premium income as well as an increase in policy acquisition-related costs associated with increased sales and an increase in policy maintenance expenses associated with the change in the mix of in-force policies from the large case market to the core market segment. 46 4356_2010AR_Fin_ALL.indd 46 4/4/11 3:05 PM Unum 2010 Annual Report Unum US Supplemental and Voluntary Operating Results Shown below are financial results and key performance indicators for Unum US supplemental and voluntary product lines.

Premium income declined in 2010 relative to 2009 for individual disability — recently issued due to lower sales. Net investment income increased in 2010 relative to 2009 due to growth in the level of assets supporting these lines of business, higher bond call premiums, and an increased level of prepayment income on mortgage-backed securities. 4356_2010AR_Fin_ALL.indd 47 47 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 The interest adjusted loss ratio for the individual disability — recently issued line of business in 2010 was consistent with 2009, with a higher rate of claim recoveries generally offsetting the higher paid claim incidence rates. The interest adjusted loss ratio for long-term care increased in 2010 relative to 2009 due primarily to an increase in the active life reserve and increased paid claim incidence rates. The benefit ratio for voluntary benefits decreased in 2010 when compared to 2009 due primarily to a lower average paid claim size in the voluntary life product line, particularly in the second half of 2010. The deferral of acquisition costs in 2010 was consistent with 2009. The amortization of deferred acquisition costs was higher in 2010 relative to 2009 due to an acceleration of amortization resulting from lower persistency for certain issue years in certain of the product lines. The other expense ratio in 2010 was consistent with the level of 2009. The individual disability — recently issued product line had goodwill of approximately $187.5 million at December 31, 2010, none of which is currently believed to be at risk for future impairment. The fair value of this product line is significantly in excess of its carrying value. In late 2010, we began a process of filing requests with various state insurance departments for a rate increase on certain of our individual long-term care policies. The rate increase reflects current interest rates, higher expected future claims, persistency, experience, and other factors related to pricing individual long-term care coverage. In states for which a rate increase is submitted and approved, customers are also given options for coverage changes or other approaches that might fit their current financial and insurance needs. Higher premium income associated with the rate increase is expected to emerge during 2011. Year Ended December 31, 2009 Compared with Year Ended December 31, 2008 Premium income increased in 2009 relative to 2008 due primarily to sales growth in the voluntary benefits product line, partially offset by a slight decline in premium persistency. Net investment income increased in 2009 relative to 2008 due to higher investment income related to growth in the level of assets supporting these lines of business, an increased level of prepayment income on mortgage- backed securities, and a higher yield on the portfolio due to the investment of new cash at higher yields than that of the existing portfolio. The interest adjusted loss ratio for the individual disability — recently issued line of business declined in 2009 relative to 2008 due primarily to a more favorable claim recovery rate and a lower number of reopened claims, partially offset by an increase in the paid incidence rate. The interest adjusted loss ratio for long-term care increased in 2009 relative to 2008 due primarily to an increase in paid claim incidence rates. The benefit ratio for voluntary benefits decreased in 2009 as compared to 2008 due primarily to an increase in premium income, partially offset by an increase in the paid claim incidence rate for the voluntary disability product line. The deferral of acquisition costs decreased in 2009 as compared to 2008 due to the decrease in acquisition-related expenses resulting from lower overall sales. The amortization of acquisition costs was higher in 2009 as compared to 2008 due to an acceleration of amortization resulting from lower persistency in certain of the product lines. The other expense ratio in 2009 was consistent with 2008. Segment Outlook During 2010, we continued to experience an unfavorable impact on premium and sales growth, particularly growth in existing customer accounts, which we attribute to the current economic environment. Partially offsetting this unfavorable impact on premiums was higher than expected premium and case persistency in our group lines of business. We believe this is temporary in nature and that persistency may return to historical levels in 2011. Opportunities for premium and sales growth are expected to re-emerge as the economy improves and employment growth resumes. We expect some volatility in net investment income to continue during 2011 as a result of fluctuations in bond calls and other types of miscellaneous net investment income. We intend to continue to manage our expense levels relative to premium levels through operating effectiveness and performance management. 48 4356_2010AR_Fin_ALL.indd 48 4/4/11 3:05 PM Unum 2010 Annual Report Periods of economic downturns have historically affected disability claim incidence rates and, to a lesser extent, disability claim recovery rates in certain sectors of the market. Certain risks and uncertainties are inherent in disability business. Components of claims experience, such as incidence and recovery rates, may be worse than we expect. Disability claim incidence and claim recovery rates may be influenced by, among other factors, the rate of unemployment and consumer confidence. Within the group disability market, pricing and renewal actions can be taken to react to higher claim rates, but these actions take time to implement, and there is a risk that the market will not sustain increased prices. In addition, changes in economic and external conditions may not manifest themselves in claims experience for an extended period of time. The current economic conditions may lead to a higher rate of claim incidence or lower levels of claim recoveries. We have previously taken steps to improve our risk profile, including reducing our exposure to volatile business segments through diversification by market size, product segment, and industry segment. We believe our claims management organization is positioned for stable and sustainable performance levels. The level of disability claims incidence in 2010 was generally consistent with what we experienced in the second half of 2009. We are uncertain as to whether the higher claim incidence is due to the normal volatility that occurs in our group disability business or is related to the economy. We continuously monitor key indicators to assess our risks and attempt to adjust our business plans accordingly. We believe our Unum US growth strategy is sound and that we will be able to leverage the capabilities, products, and relationships and reputation we have built to deliver growth as the benefits market stabilizes. We continue to see future growth opportunity based on employee choice, defined employer funding, simple administration, and effective communication. We intend to maintain our discipline and will continue (i) directing the majority of our investments to capture opportunities emerging in our core group and voluntary markets to grow them at above-market rates, (ii) focusing on margins in large case group insurance, while leveraging core market, voluntary, and other shorter-term investments to grow at market rates, and (iii) seeking opportunities to improve margins and return in our supplemental lines of business. We believe we are well-positioned strategically in our markets and that opportunities for continued disciplined growth exist in our group core market segment and in the voluntary markets. While the current economic conditions have impacted our ability to grow premium income and will continue to do so until we return to a more normal economic environment, we expect to achieve marginal year over year growth in our premium income during 2011. We anticipate that the 2011 benefit ratio in our group disability product line will be generally consistent with the level of 2010. We think future profit margin improvement is achievable, driven primarily by our continued product mix shift and expense efficiencies as our claims performance gradually flattens. Unum UK Segment The Unum UK segment includes insurance for group long-term disability, group life, and supplemental and voluntary lines of business. The supplemental and voluntary lines of business are comprised of individual disability, critical illness, and voluntary benefits products. Unum UK’s products are sold primarily in the United Kingdom through field sales personnel and independent brokers and consultants. 4356_2010AR_Fin_ALL.indd 49 49 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Operating Results Shown below are financial results and key performance indicators for the Unum UK segment.

Unum UK’s premiums, net investment income, claims, and expenses are received or paid in pounds, and we hold pound-denominated assets to support Unum UK’s pound-denominated policy reserves and liabilities. We translate Unum UK’s pound-denominated financial statement items into dollars for our consolidated financial reporting. We translate income statement items using an average exchange rate for the reporting period, and we translate balance sheet items using the exchange rate at the end of the period. We report unrealized foreign currency translation gains and losses in accumulated other comprehensive income in our consolidated balance sheets. Fluctuations in the pound to dollar exchange rate have an effect on Unum UK’s reported financial results and our consolidated financial results. In periods when the pound weakens relative to the preceding period or periods, as occurred in 2010 and 2009 relative to 2008, translating pounds into dollars decreases current periods’ results relative to the prior period. In periods when the pound strengthens relative to the preceding period, translating into dollars increases current periods’ results in relation to the prior periods. 50 4356_2010AR_Fin_ALL.indd 50 4/4/11 3:05 PM Unum 2010 Annual Report (in millions of pounds, except ratios) 2010 % Change 2009 % Change 2008 Year Ended December 31 Operating Revenue Premium Income Group Long-term Disability Group Life Supplemental and Voluntary Total Premium Income Net Investment Income Other Income Total Benefits and Expenses Benefits and Change in Reserves for Future Benefits Commissions Deferral of Acquisition Costs Amortization of Deferred Acquisition Costs Other Expenses Total £272.3 (11.9)% £309.0 (12.6)% £353.7 110.9 37.4 420.6 110.2 0.9 531.7 281.4 28.5 (18.3) 17.4 87.4 396.4 17.9 5.1 (4.1) 38.4 (43.8) 2.3 18.1 (4.4) (1.1) (10.8) (3.1) 10.3 94.1 35.6 438.7 79.6 1.6 519.9 238.3 29.8 (18.5) 19.5 90.2 0.9 12.7 (8.3) (19.2) 33.3 (10.1) (13.6) (6.6) (8.0) 8.9 (9.4) 359.3 (11.3) 93.3 31.6 478.6 98.5 1.2 578.3 275.8 31.9 (20.1) 17.9 99.6 405.1 £173.2 1.871 Operating Income Before Income Tax and Net Realized Investment Gains and Losses £135.3 (15.8) £160.6 (7.3) Weighted Average Pound/Dollar Exchange Rate 1.543 1.554 Year Ended December 31, 2010 Compared with Year Ended December 31, 2009 Premium income decreased for 2010 relative to 2009 due primarily to lower premium growth from existing customers and pricing actions due to the competitive U.K. market, partially offset by higher persistency. Net investment income increased in 2010 relative to 2009 due primarily to an increase in the level of assets supporting this business segment as well as an increase in inflation which increased the return on bonds for which interest income is linked to a U.K. inflation index. These index-linked bonds match the claim reserves associated with certain of our group policies that provide for inflation-linked increases in benefits. The increase in net investment income attributable to these index-linked bonds was generally offset by an increase in the reserves for future claims payments related to the inflation index-linked group policies. The benefit ratio increased in 2010 relative to 2009 due primarily to unfavorable risk results for the group long-term disability product line, which was driven primarily by lower premium income and the impact of higher inflation on claim reserves associated with disability policies containing an inflation-linked benefit increase feature, as discussed above, as well as a lower level of claim resolutions. The level of disability claim incidence improved over the level of 2009. Risk results for the group life line of business were also unfavorable in 2010 when compared to 2009 due to an increase in claim size for the dependent life line of business. The deferral of acquisition costs in 2010 decreased slightly when compared to 2009 due primarily to a lower level of deferrable expenses resulting from lower levels of supplemental and voluntary sales. The decrease in amortization of deferred acquisition costs relative to 2009 is due primarily to a decrease in amortization related to internal replacement transactions. The other expense ratio in 2010 remained consistent when compared to 2009 due to a continued focus on expense management. Year Ended December 31, 2009 Compared with Year Ended December 31, 2008 Premium income declined in 2009 relative to 2008 due to lower premium growth from existing customers and also due to a decline in the in-force block of group long-term disability business resulting from lower persistency and lower sales during 2008 and 2007. Also contributing to the comparative decline was an increase in group long-term disability premium income of £2.8 million in 2008 relating to a 4356_2010AR_Fin_ALL.indd 51 51 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 non-recurring reinsurance premium on a previously acquired claims block. The decline in group long-term disability premium income was partially offset by increases in premium income for group life and supplemental and voluntary due to higher sales and improved persistency. Net investment income decreased in 2009 relative to 2008 due primarily to a reduction in inflation which reduced the return on bonds for which interest income is linked to a U.K. inflation index. The decrease in 2009 net investment income attributable to these bonds was generally offset by a comparable decrease in reserves, as previously noted. The lower benefit ratio in 2009 in comparison to 2008 was primarily due to a decline in the level of claim incidence for group long- term disability as well as the impact of lower inflation on claim reserves associated with group long-term disability policies containing the inflation-linked benefit increase feature. Partially offsetting these items was an increase in claim incidence for the group life line of business. Claim recoveries for group long-term disability were generally consistent with the level of 2008. The deferral of acquisition costs in 2009 decreased in comparison to 2008 due primarily to a lower level of deferrable expenses resulting from the reduction in the overall expense level as well as a change in the mix of sales. The increase in amortization of acquisition costs in 2009 relative to 2008 was due primarily to an increase in amortization related to internal replacement transactions.

The decrease in sales in the group long-term disability line of business was attributable to a decline in sales in the large case market, partially offset by higher sales to existing customers and higher core market sales, which we define for Unum UK as employee groups with fewer than 500 lives. The decrease in sales in supplemental and voluntary is due to a decline in sales in the large case market. The sales growth in group life was attributable to higher sales in the large case markets as well as higher sales to existing customers, partially offset by slightly lower core market sales. Negatively affecting year over year comparisons is an increase in 2009 sales which resulted from the exit of another large insurance provider from the U.K. group risk market. Sales in Unum UK increased in 2009 compared to 2008, aided by the exit of another large insurance provider from the U.K. group risk market, as previously noted. Excluding the sales related to this exit of this provider, Unum UK sales increased 8.6 percent in 2009 compared to 2008. The sales growth in group life was attributable to sales growth in both the core market and in the large case market, partially offset by lower sales to existing customers. The decline in group long-term disability sales was due to a decrease in sales to existing customers, partially offset by sales growth in both the core and large case markets. The increase in sales in supplemental and voluntary was due to sales growth in both the core and large case markets. 52 4356_2010AR_Fin_ALL.indd 52 4/4/11 3:05 PM Unum 2010 Annual Report Segment Outlook During 2010, we experienced an unfavorable impact on premium growth as a result of the challenging economic and competitive pricing environment. We expect this may continue in the near term if current economic and competitive conditions in the U.K. persist. Our sales growth may also be impacted by a prolonged competitive pricing environment in the U.K. The level of disability claim incidence in 2010 is favorable relative to 2009, but our claim resolution rate is unfavorable to 2009, due in part to the impact of the economic environment on our ability to resolve claims. We continuously monitor key indicators to assess our risks and attempt to adjust our business plans accordingly. Continued fluctuations in the U.S. dollar relative to the British pound sterling impact our reported operating results. Our current growth strategy focuses on generating organic growth and expanding our role as the leading provider of group disability insurance in the U.K. Our strategy for future growth combines optimizing the performance of our existing business while developing new market opportunities. We intend to optimize performance of the existing business by (i) increasing underwriting and pricing discipline, (ii) improving our claims management processes, and (iii) expanding our broker market capabilities and sales effectiveness. We intend to develop new market opportunities by raising awareness of the need for income protection and by offering a suite of employee paid workplace solutions using integrated products with simpler, defined choices and flexible funding options through a streamlined and efficient platform with online capabilities matched to broker and employer needs. In the current competitive pricing market and economic environment, we continue to have a cautious outlook for premium growth in 2011 and anticipate negative earnings growth relative to 2010. We anticipate returning to more normalized levels of premium growth through continued favorable persistency and price increases, as well as increased sales to existing and new customers which we expect to occur commensurate with the timing of the U.K. economic recovery. We expect our overall benefit ratio to be generally consistent with that of 2010. We expect our profit margins to continue at a favorable level, although slightly below the level of 2010. 4356_2010AR_Fin_ALL.indd 53 53 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Colonial Life Segment The Colonial Life segment includes insurance for accident, sickness, and disability products, life products, and cancer and critical illness products issued primarily by Colonial Life & Accident Insurance Company and marketed to employees at the workplace through an agency sales force and brokers.

Although the premium growth rate improved over the rate of 2009, it is still less than our long-term expectations. Premium growth was negatively impacted during both 2010 and 2009 due to economic conditions which we believe affected the buying patterns of employees and caused employers to defer introduction of new plans. Net investment income increased in 2010 in comparison to 2009 due to growth in the level of assets, an increase in income from partnership investments, and an increase in bond call premiums. The overall benefit ratio increased in 2010 relative to 2009 due to unfavorable experience in the accident, sickness, and disability product line resulting from an increase in the level of paid claims and reserves driven by a higher level of claim incidence and slightly higher average claim sizes. The cancer and critical illness benefit ratio increased relative to 2009 due primarily to the continued higher levels of large claims on the older block of cancer products, partially offset by a refinement of the loss adjustment expense reserve calculation. Somewhat negatively affecting year over year comparisons is the release of active life reserves in the second quarter of 2009 in our cancer and critical illness product line. The life benefit ratio decreased in 2010 relative to 2009 due primarily to favorable mortality. Commissions and the deferral of acquisition costs both increased in 2010 compared to 2009 due primarily to increased sales. The amortization of deferred acquisition costs in 2010 was higher relative to 2009 due to the continued increase in the level of deferred acquisition costs, offset partially by the decrease in amortization related to certain of our interest-sensitive policies. The other expense ratio decreased in 2010 compared to 2009 due primarily to a continued focus on expense management. Year Ended December 31, 2009 Compared with Year Ended December 31, 2008 The lower level of premium growth in 2009 compared to the 2008 growth rate was attributable primarily to lower sales during the first half of 2009 and lower persistency in the accident, sickness, and disability product line. The lower persistency primarily relates to the loss of a few large policyholder accounts. As mentioned in the preceding discussion, we believe our lower premium growth was partially due to economic conditions. Net investment income increased in 2009 in comparison to 2008 due to growth in the level of assets, an increased level of prepayment income on mortgage-backed securities, and a higher yield on the portfolio due to the investment of new cash at a higher yield than that of the existing portfolio. The overall benefit ratio for this segment remained stable in 2009 relative to 2008, with a lower benefit ratio in the life and cancer and critical illness lines of business partially offset by a slightly higher benefit ratio in the accident, sickness, and disability line of business. The life product line reported a lower benefit ratio in 2009 relative to 2008 due to a change in the mix of life business and the resulting lower change in the active life reserve. The cancer and critical illness product line reported a lower benefit ratio in 2009 relative to 2008 due primarily to a release of active life reserves, partially offset by an increase in disabled life reserves associated with the older cancer products. The increase in the benefit ratio in the accident, sickness and disability line of business resulted primarily from a slight increase in the claim incidence rates relative to the favorable experience of 2008. The amortization of deferred acquisition costs was higher in 2009 relative to 2008 due to the continued increase in the level of deferred acquisition costs as well as the fluctuation in amortization related to certain of our interest-sensitive policies. The other expense ratio was consistent year over year.

New account sales increased 4.2 percent, and existing account sales increased 4.4 percent in 2010 relative to 2009. Sales increased 8.1 percent in 2010 in the commercial market, driven primarily by sales growth of 9.3 percent in the core market segment, which we define as accounts with fewer than 1,000 lives. In the public sector market, sales declined 8.1 percent in 2010 compared to 2009. The number of new accounts in 2010 increased 13.6 percent relative to 2009, while the average new case size declined 8.2 percent. Colonial Life’s sales in 2009 increased 1.1 percent relative to 2008, with 7.2 percent growth in new account sales and a decline of 2.3 percent in existing account sales. We experienced 2009 sales growth of 11.8 percent relative to 2008 in the public sector market and a slight increase in sales in commercial large case market segment. These sales increases were partially offset by a sales decline of 2.6 percent in the commercial core market segment. The number of new accounts increased 13.3 percent in 2009 relative to 2008, while the average new case size declined 5.4 percent. Segment Outlook Our premium growth in 2010 improved from the level of growth in 2009, driven by modest 2010 sales growth and improved persistency. Persistency in 2009 was negatively impacted by the loss of a few large policyholder accounts. While we are encouraged by our 2010 sales results, slower sales and premium growth levels may continue in the near term if the current economic conditions persist and continue to affect employment growth, the buying patterns of employees, and the deferral by employers of the introduction of new employee benefit plans. Periods of economic downturns have historically had minimal impact on the risk results of Colonial Life, due primarily to a diversified product portfolio that is designed with short duration, indemnity benefits. During 2010, we experienced an increase in claim incidence levels in the accident, sickness, and disability line. However, there was not a concentration in any particular market sector. We continuously monitor key indicators to assess our risks and attempt to adjust our business plans accordingly. We believe we have a stable business model, with service levels and customer retention that allowed us to focus on and deliver premium growth during 2010 despite the recent marketplace changes and uncertainties. We believe we are well positioned for growth and that significant opportunities exist to accelerate growth during the next several years by (i) focusing on target market segments, (ii) driving new sales in the public sector market, (iii) growing the reach and effectiveness of our distribution, and (iv) revisiting existing accounts to avoid lapses and to generate ongoing sales. During 2011, we expect premium growth to be modest relative to our long-term outlook. We believe that strong profit margins will continue, although we expect our overall benefit ratio to be slightly higher than the favorable risk experience of 2009 and the first half of 2010. We believe premium growth will reaccelerate as the economy improves and employment growth resumes. Individual Disability — Closed Block Segment The Individual Disability — Closed Block segment generally consists of those individual disability policies in-force before the substantial changes in product offerings, pricing, distribution, and underwriting, which generally occurred during the period 1994 through 1998. A small amount of new business continued to be sold after these changes, but we stopped selling new policies in this segment at the beginning of 2004 other than update features contractually allowable on existing policies. 56 4356_2010AR_Fin_ALL.indd 56 4/4/11 3:05 PM Unum 2010 Annual Report Operating Results Shown below are financial results and key performance indicators for the Individual Disability — Closed Block segment.

Net investment income for 2010 was slightly higher than 2009, with higher bond call premiums mostly offset by a lower level of assets supporting this closed block of business. Other income, which includes the underlying results of certain blocks of reinsured business and the net investment income of portfolios held by those ceding companies to support the block we have reinsured, decreased in 2010 relative to 2009 due to less favorable investment results from the portfolios held by the ceding companies as well as less favorable risk results from the reinsured business. The interest adjusted loss ratio for 2010 increased relative to 2009 due to lower claim recoveries and lower claim settlements, partially offset by lower claim incidence rates. Interest and debt expense in 2010 declined when compared to 2009 due to lower rates of interest on our floating rate debt issued by Northwind Holdings and a decrease in the amount of outstanding debt resulting from principal repayments. The other expense ratio decreased in 2010 compared to 2009 due primarily to lower claims management and claim litigation costs relative to the declining level of premium income. 4356_2010AR_Fin_ALL.indd 57 57 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Year Ended December 31, 2009 Compared with Year Ended December 31, 2008 Premium income declined in 2009 relative to 2008 as expected for the run-off of this block of closed business. Net investment income decreased in 2009 relative to 2008 due to lower interest rates on floating rate assets as well as a lower level of assets supporting this closed block of business, partially offset by an increased level of prepayment income on mortgage-backed securities. We also received fewer bond call premiums and consent fees during 2009 compared to 2008. Other income increased slightly in 2009 compared to 2008 due to favorable experience in the reinsured blocks. The interest adjusted loss ratio for 2009 declined slightly relative to 2008 due to higher claim recoveries. Interest and debt expense decreased in 2009 relative to 2008 due to lower rates of interest on our floating rate debt issued by Northwind Holdings and a decrease in the amount of outstanding debt resulting from principal repayments. The other expense ratio increased slightly in 2009 when compared to 2008 due primarily to the decline in premium income. Included in 2008 other expenses is a $4.7 million litigation settlement. Segment Outlook We expect that this segment may experience volatility in net investment income due to the variability in interest rates on floating rate assets and also due to volatility of bond call premiums relative to historical levels. A portion of the volatility in interest income will be offset by commensurate changes in the interest expense on our floating rate debt. We expect that operating revenue and income will continue to decline over time as this closed block of business winds down. We believe that the interest adjusted loss ratio for this block of business will be relatively flat over the long term, but the segment may experience quarterly volatility. Claim resolution rates, which measure the resolution of claims from recovery, deaths, settlements, and benefit expirations, are very sensitive to operational and environmental changes and can be volatile. Our claim resolution rate assumption used in determining reserves is our expectation of the resolution rate we will experience over the life of the block of business and will vary from actual experience in any one period. It is possible that variability in our reserve assumptions could result in a material impact on our reserve levels. Corporate and Other Segment The Corporate and Other segment includes investment income on corporate assets not specifically allocated to a line of business, interest expense on corporate debt other than non-recourse debt, and certain other corporate income and expense not allocated to a line of business. Corporate and Other also includes results from certain Unum US insurance products not actively marketed, including individual life and corporate-owned life insurance, reinsurance pools and management operations, group pension, health insurance, and individual annuities. We expect operating revenue and income resulting from these insurance products to decline over time as these business lines wind down. 58 4356_2010AR_Fin_ALL.indd 58 4/4/11 3:05 PM Unum 2010 Annual Report Operating Results (in millions of dollars) Operating Revenue Premium Income Net Investment Income Other Income Total Benefits and Expenses Benefits and Change in Reserves for Future Benefits Commissions Interest and Debt Expense Other Expenses Total Operating Loss Before Income Tax and Net Year Ended December 31 2010 % Change 2009 % Change 2008 $ 3.5 29.6% $ 2.7 92.9% $ 1.4 192.3 25.7 221.5 82.9 1.1 128.9 63.2 276.1 15.4 (26.1) 8.5 (9.8) 175.0 20.7 (1.7) 4.8 166.7 34.8 204.2 91.9 0.4 106.8 64.3 263.4 (15.6) (17.5) (15.3) (14.7) (66.7) (9.0) 124.0 3.3 197.5 42.2 241.1 107.8 1.2 117.4 28.7 255.1 Realized Investment Gains and Losses $ (54.6) 7.8 $ (59.2) N.M. $ (14.0) N.M. = not a meaningful percentage Non-Insurance Product Results Operating revenue was $97.9 million in 2010 compared to $71.1 million and $106.0 million in 2009 and 2008, respectively. Operating losses were $71.1 million in 2010 compared to $91.9 million and $30.6 million in 2009 and 2008, respectively. The increase in operating revenue in 2010 compared to 2009 is due to higher net investment income resulting from higher asset levels and a higher proportion of assets invested at long-term interest rates, partially offset by lower interest rates on short-term investments. The decrease in operating revenue in 2009 compared to 2008 is due primarily to a decrease in net investment income resulting from lower interest rates on short-term investments. Operating revenue in 2008 included $7.6 million of other income received during 2008 related to a refund of interest primarily attributable to tax years 1986 through 1996. Interest and debt expense increased in 2010 compared to 2009 due primarily to the September 2010 issuance of $400.0 million of 5.625% senior notes and the September 2009 issuance of $350.0 million of 7.125% senior notes. The higher interest and debt expense associated with the two new debt issuances was partially offset by the repayment of $10.0 million of 7.08% medium-term notes due 2024 during the first quarter of 2010 and the repayment of $108.2 million of 5.859% senior notes during the second quarter of 2009. Interest and debt expense declined in 2009 relative to 2008 due primarily to lower average levels of outstanding debt. See “Debt” contained in this Item 7 for further discussion. Other expenses were $40.1 million in 2010 compared to $56.2 million and $19.2 million in 2009 and 2008, respectively. The volatility in other expenses is due primarily to pension costs, which increased approximately $42.0 million in 2009 relative to 2008 and declined approximately $15.0 million in 2010 relative to 2009. Insurance Product Results Operating revenue for our insurance products was $123.6 million in 2010 compared to $133.1 million and $135.1 million in 2009 and 2008, respectively. These closed lines of business had operating income of $16.5 million in 2010 compared to $32.7 million and $16.6 million in 2009 and 2008, respectively. Operating expenses were higher in 2010 compared to 2009 due to increased litigation costs. 4356_2010AR_Fin_ALL.indd 59 59 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Segment Outlook Our investment portfolio quality remains very strong, with low default experience during 2010. We are currently holding capital at our insurance subsidiaries and holding companies at levels that exceed our long-term requirements. We expect to continue to generate excess capital on an annual basis through strong statutory earnings. During 2011, while we intend to maintain our disciplined approach to risk management, we believe we are well-positioned wherein we have substantial flexibility to preserve our capital strength and at the same time explore opportunities to deploy the excess capital that is generated each period. Interest and debt expense is expected to remain generally consistent with the level of 2010 due to $225.1 million of debt which will mature in March 2011 and no expected issuances of new debt in 2011. We do not expect litigation costs to remain at the elevated level of 2010, and pension expenses are expected to remain generally consistent in 2011 with the level of 2010. Investments Overview Our investment portfolio is well diversified by type of investment and industry sector. We have established an investment strategy that we believe will provide for adequate cash flows from operations and allow us to hold our securities through periods where significant decreases in fair value occur. We believe our emphasis on risk management in our investment portfolio, including credit and interest rate management, has positioned us well and generally reduced the volatility in our results. We have no exposure to subprime mortgages, “Alt-A” loans, or collateralized debt obligations in our asset-backed, mortgage-backed securities, or public bond portfolios. At December 31, 2010, we had minimal exposure to investments for which the payment of interest and principal is guaranteed under a financial guaranty insurance policy, and all such securities are rated investment-grade absent the guaranty insurance policy. We held $378.0 million fair value ($374.3 million amortized cost) of perpetual debentures, or “hybrid” securities, that generally have no fixed maturity date. Interest on these securities due on any payment date may be deferred by the issuer. The interest payments are generally deferrable only to the extent that the issuer has suspended dividends or other distributions or payments to any of its shareholders or any other perpetual debt instrument. Below is a summary of our formal investment policy, including the overall quality and diversification objectives: • The majority of investments are in high quality publicly traded securities to ensure the desired liquidity and preserve the capital value of our portfolios. • The long-term nature of our insurance liabilities also allows us to invest in less liquid investments to obtain superior returns. A maximum of 10 percent of the total investment portfolio may be invested in below-investment-grade securities, 2 percent in equity type instruments, up to 35 percent in private placements, and 10 percent in commercial mortgage loans. The remaining assets can be held in publicly traded investment-grade corporate securities, mortgage-backed securities, bank loans, asset-backed securities, government and government agencies, and municipal securities. • We intend to manage the risk of losses due to changes in interest rates by matching asset duration with liabilities, in the aggregate. • The weighted average credit quality rating of the portfolio should be Baa1 or higher. • The maximum investment per issuer group is limited based on internal limits reviewed by the finance committee of Unum Group’s board of directors and approved by the boards of directors of our insurance subsidiaries and is more restrictive than the five percent limit generally allowed by the state insurance departments which regulate the type of investments our insurance subsidiaries are allowed to own. These internal limits are as follows: 60 4356_2010AR_Fin_ALL.indd 60 4/4/11 3:05 PM Unum 2010 Annual Report Rating AAA/AA A BBB+ BBB BBB- BB+ BB BB- B+ B/B- CCC Internal Limit ($ in millions) $200 175 150 125 90 75 60 50 30 20 10 • The portfolio is to be diversified across industry classification and geographic lines. • Derivative instruments may be used to replicate permitted asset classes, hedge interest rate risk and foreign currency risk, and match liability duration and cash flows consistent with the plan reviewed by the finance committee of Unum Group’s board of directors and approved by the boards of directors of our insurance subsidiaries. • Asset mix guidelines and limits are established by us, reviewed by the finance committee of Unum Group’s board of directors, and approved by the boards of directors of our insurance subsidiaries. • The allocation of assets and the selection and timing of the acquisition and disposition of investments are subject to ratification, on a weekly basis, by an investment subcommittee appointed by the boards of directors of our insurance subsidiaries. These actions are also reviewed by the finance committee of Unum Group’s board of directors on a quarterly basis. • We review these investment policies and guidelines annually, or more frequently if deemed necessary, and recommend adjustments, as appropriate. Any revisions are reviewed by the finance committee of Unum Group’s board of directors and must be approved by the boards of directors of our insurance subsidiaries. See “Critical Accounting Estimates” contained herein for further discussion of our valuation of investments. Investment Results Net investment income was $2,495.5 million in 2010, an increase of 6.3 percent relative to 2009. Net investment income was higher in 2010 relative to 2009 due primarily to continued growth in the level of invested assets and higher bond call premiums. We also received higher interest income during 2010 on bonds for which interest income is linked to a U.K. inflation index. These index-linked bonds match the claim reserves associated with certain of our Unum UK group policies that provide for inflation-linked increases in benefits, with the increase or decrease in investment income on these bonds generally offset by an increase or decrease in reserves. In addition, we earned lower interest rates on our floating rate invested assets during 2010 compared to 2009, largely offset by lower interest expense on our floating rate debt. Net investment income was $2,346.6 million in 2009, a decrease of 1.8 percent relative to 2008. The weaker pound in 2009 relative to 2008 unfavorably affected translated results for net investment income. During 2009, we also received lower investment income on bonds for which interest income is linked to a U.K. inflation index, as compared to 2008, and we earned lower interest rates on our floating rate invested assets during 2009. We also received fewer bond call premiums and consent fees during 2009 compared to 2008. Somewhat mitigating the impact of these items was the growth in the level of invested assets, an increase in the level of prepayment income on mortgage-backed securities, and an increase in our portfolio yield due to the investment of new cash at higher rates than that of 2008. 4356_2010AR_Fin_ALL.indd 61 61 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 The duration weighted book yield on the fixed income securities in our investment portfolio was 6.71 percent as of December 31, 2010, and the weighted average credit rating was A3. This compares to a yield of 6.74 percent as of December 31, 2009 and a weighted average credit rating of A3. We actively manage our asset and liability cash flow match and our asset and liability duration match to limit interest rate risk. Duration is a measure of the percentage change in the fair values of assets and liabilities for a given change in interest rates. Cash flows from the in-force asset and liability portfolios are projected at current interest rate levels and also 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. To assess the impact of a duration mismatch, we measure the potential changes in estimated fair value based on a hypothetical change in interest rates to quantify a dollar value change. At December 31, 2010, a hypothetical one basis point increase or decrease in interest rates would have resulted in a $33.0 million change in the fair value of our liabilities and an offsetting $31.8 million change in the fair value of assets supporting those liabilities. 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 more on long-term measures such as reserve adequacy analysis and the relationship between the portfolio yields supporting our various product lines and the aggregate discount rates embedded in the reserves.

The company recorded significant impairment losses in its securities and real estate portfolios during 2009 and 2008 and required a significant amount of government aid. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than three years • During 2009, we recognized an other-than-temporary impairment loss of $33.3 million on securities issued by a U.S. media conglomerate. The company reported mixed fourth quarter 2008 operating results as its outdoor advertising weakened significantly. During the first quarter of 2009, the company borrowed $1.6 billion against its lines of credit and completed a tender/exchange offer to improve its near term debt maturity profile. Continued signs that the company’s operations had weakened materially in the first quarter 2009, as well as the continued weakness in the economy, led us to believe that covenant violations could occur in the near future. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than three years. 62 4356_2010AR_Fin_ALL.indd 62 4/4/11 3:05 PM Unum 2010 Annual Report • During 2009, we recognized an other-than-temporary impairment loss of $32.9 million on securities issued by a U.K. financial institution. The decline in value of the securities was primarily the result of the global credit crisis and the slowdown in the economy. In addition, this financial institution made a major acquisition during the peak of the past credit cycle. The financial institution then had to recognize impairments on loans and other assets held by the acquired company, resulting in the need for additional capital. This capital was initially provided by shareholders and others, but as the economic environment further deteriorated, the financial institution participated in the government guarantee of senior debt, capital injections, and an asset protection scheme. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than three years. • During 2009, we recognized an other-than-temporary impairment loss of $23.9 million on securities issued by a U.S. automotive parts company. Due to the weak economy, automobile production had decreased dramatically, with the expectation of further production reductions at the time of the impairment loss. Declining earnings caused the company to be out of compliance with covenants in certain of its debt issues. The company eventually obtained waivers on these covenants, the terms of which precluded the company from making interest payments on certain of its other debt issues. The company was unable to cure this default within the grace period and ultimately was forced to file for bankruptcy. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than three years. • During 2009, we recognized an other-than-temporary impairment loss of $23.7 million on principal protected equity linked trust certificates representing our investment in a trust which held forward contracts to purchase shares of a Vanguard S&P 500 index mutual fund. We recognized the other-than-temporary impairment loss because we intended to sell the security. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than one year but less than two years. • During 2009, we recognized an other-than-temporary impairment loss of $20.1 million on securities issued by a large specialty chemical company. The company reported fourth quarter 2008 earnings that were weaker than expected, which limited its prospects of refinancing its 2009 debt maturities. The company had been pursuing asset sales to raise cash but was unable to do so in time to avoid a financial restructuring. During the first quarter of 2009, the company filed for bankruptcy protection. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than two years but less than three years. • During 2009, we recognized an other-than-temporary impairment loss of $19.5 million on securities issued by a U.S. automotive parts company. The majority of the company’s revenues were generated by sales to a single domestic automobile manufacturer. Due to the weak economy, automobile production had decreased dramatically, with the expectation of further production cuts. The U.S. government made available a $5 billion credit facility to several automotive parts companies to help maintain automotive supplier liquidity. However, with their largest customer likely to undergo a major financial restructuring and/or bankruptcy filing, the company faced increased challenges. In March 2009 its external auditors stated there was “substantial doubt” about the company’s ability to continue as a going concern if the automotive industry’s financial problems were not resolved soon. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than three years. • During 2009, we recognized an other-than-temporary impairment loss of $17.5 million on securities issued by a U.K. financial institution. During 2008, a significant decrease in funding liquidity ultimately required the U.K. government to nationalize this institution. In this process, the government provided guarantees on deposits, senior debt, and loans. Since 2008, the company initiated several programs to improve its liquidity and to repay the loans to the government. In the first quarter of 2009, the company announced it had developed a plan for a legal and capital restructuring of the company, which it expected to complete in the second half of 2009. During the second quarter of 2009, the company submitted its plan to the European Commission (EC) and requested permission to begin the program under EC competition rules. The EC released various aspects of the company’s restructuring plan, which included splitting the company into multiple entities. It appeared we would be unable to recover the entire cost basis of our securities, which are subordinate to the government’s debt as well as other creditors. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than two years but less than three years. 4356_2010AR_Fin_ALL.indd 63 63 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 • During 2008, we recognized an other-than-temporary impairment loss of $39.3 million on a principal protected equity linked note which contained an embedded forward contract to purchase shares of a Vanguard S&P 500 index mutual fund. The note also provided principal protection through the substitution of highly rated bonds in place of the underlying S&P 500 index mutual fund, should a specified trigger event occur. At the time of the impairment loss, the decline in the S&P 500 index had not been significant enough to trigger the substitution of the highly rated bonds, but due to the then recent steep decline in the S&P 500 index, we could no longer conclude that the value of the underlying S&P 500 index mutual fund would equate to or exceed the par value of the security at maturity. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than three years. • During 2008, we recognized an other-than-temporary impairment loss of $32.0 million on securities issued by a U.S. based automobile manufacturer and its captive finance subsidiary. The company experienced a decline in profitability and cash flow due to the weak economic environment. Although at the time of the impairment loss the company had not yet received government bailout money, the probability of receiving some form of government financial aid had significantly increased. Other U.S. automakers that had received bailout money were expected to request their bondholders to accept a significant reduction in principal. In order for this company to stay competitive with other U.S. automakers, it was likely that it, too, would seek debt relief from its bondholders and that we would not recover our entire principal for these securities. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than three years. • During 2008, we recognized an other-than-temporary impairment loss of $27.8 million on securities issued by a large investment banking firm. The company experienced a rapid deterioration in its credit and derivatives portfolio, which made it impossible for the firm to raise additional capital or to sell assets to increase liquidity. The inability to raise capital forced the company to file for bankruptcy protection in the third quarter of 2008. The firm was rated A2 by Moody’s and A by S&P at the time of the bankruptcy filing. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than two years but less than three years. • During 2008, we recognized an other-than-temporary impairment loss of $21.6 million on securities issued by a large publisher of yellow page advertising. The outlook for this industry had continued to worsen due to the secular change impacting the industry and due to weak economic conditions. The company’s third quarter 2008 earnings were down significantly as compared to prior periods, and bad debt expense and financial leverage increased significantly. These financial results increased the likelihood that the company might violate bank covenants and seek waivers from its bondholders. Additionally, the company had hired external consultants to advise it on potential capital restructuring alternatives. These events increased the likelihood that the company would seek to tender its bonds at a discounted value and that our bonds would not fully recover in value. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than one year but less than two years. • During 2008, we recognized an other-than-temporary impairment loss of $12.9 million on securities issued by a large international chemical company. The company’s third quarter 2008 operating results were weak due to recessionary industry conditions and the negative impact of hurricane activity on its oil refinery operations. Due to these factors, the company experienced a significant decline in its liquidity. In late December 2008, lenders denied the company’s request to obtain additional funding from its existing line of credit. As a result, the company’s liquidity was insufficient to fund required cash outflows, and the company hired external consultants to advise it on potential capital restructuring alternatives. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than one year but less than two years. • During 2008, we recognized an other-than-temporary impairment loss of $12.1 million on securities issued by a large newspaper publishing company. The outlook for this industry had continued to deteriorate due to the secular change away from newspaper advertising and weak economic conditions. The company reported poor third quarter 2008 operating results. The increase in leverage and lower cash flows increased the likelihood that the company might violate its bank covenants. The company had attempted to sell non-core assets to reduce its debt, but it had been unable to execute a sale. As a result, it was likely that our bonds would not fully recover in value. At the time of the impairment loss, these securities had been in an unrealized loss position for a period of greater than two years but less than three years. 64 4356_2010AR_Fin_ALL.indd 64 4/4/11 3:05 PM Unum 2010 Annual Report Realized Investment Losses $10.0 Million or Greater from Sale of Fixed Maturity Securities • We had no individual realized investment losses of $10.0 million or greater from the sale of fixed maturity securities during 2010. • During 2009, we recognized a loss of $14.2 on the sale of securities issued by a large publisher of yellow page advertising. The company had suffered from deterioration in print directories’ advertising as well as a significant rise in bad debt expenses due to the impact of the recession on small business customers. The company maintained significant amounts of available cash and was still generating free cash flows despite the weakening economy. However, during the first quarter of 2009, the company announced that it had hired a financial adviser to review its capital structure alternatives regarding debt payments due in 2010. At the time of disposition, these securities had been in an unrealized loss position for a period of greater than three years. • During 2008, we recognized a loss of $16.2 million on the sale of securities issued by a large investment banking firm for which we had recorded an impairment loss in 2008, as previously discussed. • During 2008, we recognized a loss of $10.1 million on the disposition of the principal protected equity linked note, as previously discussed. The note’s substitution clause was triggered in the fourth quarter of 2008 due to the continued decline in the S&P 500 index. At the time of the triggering event, we made the decision to take ownership in the underlying Vanguard S&P 500 index mutual fund shares rather than accept the zero coupon bonds issued by the financial services company. At the time of disposition, this note had been continuously in an unrealized loss position for a period of less than ninety days. Embedded Derivative in a Modified Coinsurance Arrangement We report changes in the fair value of an embedded derivative in a modified coinsurance arrangement as realized investment gains and losses, as required under the provisions of GAAP. GAAP requires us to include in our realized investment gains and losses a calculation intended to estimate the value of the option of our reinsurance counterparty to cancel the reinsurance contract with us. However, neither party can unilaterally terminate the reinsurance agreement except in extreme circumstances resulting from regulatory supervision, delinquency proceedings, or other direct regulatory action. Cash settlements or collateral related to this embedded derivative are not required at any time during the reinsurance contract or at termination of the reinsurance contract, and any accumulated embedded derivative gain or loss reduces to zero over time as the reinsured business winds down. We therefore view the effect of realized gains and losses recognized for this embedded derivative as a reporting requirement that will not result in a permanent change in assets or stockholders’ equity. The changes in fair value of this embedded derivative recognized as realized gains and losses during 2010, 2009 and 2008 resulted primarily from a change in credit spreads in the overall investment market. The fair value of this embedded derivative was $(96.3) million at December 31, 2010, compared to $(117.4) million at December 31, 2009, and is reported in other liabilities in our consolidated balance sheets. 4356_2010AR_Fin_ALL.indd 65 65 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Fixed Maturity Securities The fair value and associated unrealized gains and losses of our fixed maturity securities portfolio, by industry classification, as of December 31, 2010 are as follows: Fixed Maturity Securities — By Industry Classification As of December 31, 2010 (in millions of dollars) Classification Basic Industry Capital Goods Communications Consumer Cyclical Consumer Non-Cyclical Energy (Oil & Gas) Financial Institutions Mortgage/Asset-Backed Sovereigns Technology Transportation U.S. Government Agencies and Municipalities Utilities Redeemable Preferred Stocks Fair Value of Fixed Maturity Securities with Gross Net Unrealized Gain (Loss) Unrealized Loss Gross Unrealized Loss Fair Value of Fixed Maturity Securities with Gross Unrealized Gain Gross Unrealized Gain Fair Value $ 2,154.0 $ 140.4 $ 325.4 $ 16.8 $ 1,828.6 $ 157.2 3,511.3 2,678.0 1,305.4 5,067.8 3,212.3 3,330.1 3,385.5 1,409.3 857.7 1,038.1 2,346.9 9,684.2 55.0 323.9 303.0 72.2 507.2 407.9 113.7 337.7 160.7 92.3 126.6 94.2 810.0 (0.8) 389.3 245.3 275.5 341.7 47.7 960.5 80.0 — 90.8 62.7 795.7 1,114.8 28.3 14.6 14.5 22.4 17.6 3.7 39.1 0.6 — 3.0 2.4 55.9 44.3 2.5 3,122.0 2,432.7 1,029.9 4,726.1 3,164.6 2,369.6 3,305.5 1,409.3 766.9 975.4 1,551.2 8,569.4 26.7 338.5 317.5 94.6 524.8 411.6 152.8 338.3 160.7 95.3 129.0 150.1 854.3 1.7 Total $40,035.6 $3,489.0 $4,757.7 $237.4 $35,277.9 $3,726.4 66 4356_2010AR_Fin_ALL.indd 66 4/4/11 3:05 PM Unum 2010 Annual Report The following two tables show the length of time our investment-grade and below-investment-grade fixed maturity securities had been in a gross unrealized loss position as of December 31, 2010 and at the end of the prior four quarters. The relationships of the current fair value to amortized cost are not necessarily indicative of the fair value to amortized cost relationships for the securities throughout the entire time that the securities have been in an unrealized loss position nor are they necessarily indicative of the relationships after December 31, 2010. We had no fixed maturity securities with a gross unrealized loss of $10.0 million or greater at December 31, 2010.

The mortgage/asset-backed securities are valued on a monthly basis using valuations supplied by the brokerage firms that are dealers in these securities as well as independent pricing services. One of the risks involved in investing in mortgage/asset-backed securities is the uncertainty of the timing of cash flows from the underlying loans due to prepayment of principal with the possibility of reinvesting the funds in a lower interest rate environment. We use models which incorporate economic variables and possible future interest rate scenarios to predict future prepayment rates. The timing of prepayment cash flows may also cause volatility in our recognition of investment income. We recognize investment income on these securities using a constant effective yield based on projected prepayments of the underlying loans and the estimated economic life of the securities. Actual prepayment experience is reviewed periodically, and effective yields are recalculated when differences arise between prepayments originally projected and the actual prepayments received and currently projected. The effective yield is recalculated on a retrospective basis, and the adjustment is reflected in net investment income. We have not invested in mortgage-backed derivatives, such as interest-only, principal-only, or residuals, where market values can be highly volatile relative to changes in interest rates. All of our mortgage-backed securities have fixed rate coupons. The credit quality of our mortgage-backed securities portfolio has not been negatively impacted by the issues in the market concerning subprime mortgage loans. The change in value of our mortgage-backed securities portfolio has moved in line with that of prime agency-backed mortgage-backed securities. As of December 31, 2010, the amortized cost and fair value of our below-investment-grade fixed maturity securities was $2,668.9 million and $2,755.0 million, respectively. Below-investment-grade securities are inherently more risky than investment-grade securities since the risk of default by the issuer, by definition and as exhibited by bond rating, is higher. Also, the secondary market for certain below-investment-grade issues can be highly illiquid. Additional downgrades may occur, but we do not anticipate any liquidity problems resulting from our investments in below-investment-grade securities, nor do we expect these investments to adversely affect our ability to hold our other investments to maturity. 68 4356_2010AR_Fin_ALL.indd 68 4/4/11 3:05 PM Unum 2010 Annual Report Mortgage Loans Our mortgage loan portfolio was $1,516.8 million and $1,404.0 million on an amortized cost basis at December 31, 2010 and 2009, respectively. Our mortgage loan portfolio is comprised entirely of commercial mortgage loans. We believe our mortgage loan portfolio is well diversified geographically and among property types. The incidence of problem mortgage loans and foreclosure activity continues to be low. Due to conservative underwriting, we expect the level of problem loans to remain low relative to the industry. At December 31, 2010, we held two mortgage loans which were considered impaired. The mortgage loans were carried at the estimated net realizable value of $22.9 million, net of a valuation allowance of $1.5 million. At December 31, 2009, we held one mortgage loan which was considered impaired. This loan was carried at the estimated net realizable value of $2.0 million, net of a valuation allowance of $3.2 million. Derivative Financial Instruments We use derivative financial instruments primarily to manage reinvestment risk, duration, and currency risk. Historically, we have utilized current and forward interest rate swaps and options on forward interest rate swaps, current and forward currency swaps, forward treasury locks, currency forward contracts, and forward contracts on specific fixed income securities. Our current credit exposure on derivatives, which is limited to the value of those contracts in a net gain position less collateral held, was $14.8 million at December 31, 2010. The carrying value of fixed maturity securities posted as collateral to our counterparties was $158.8 million at December 31, 2010. We believe that our credit risk is mitigated by our use of multiple counterparties, all of which are rated A or better by both Moody’s and S&P, and by our use of cross-collateralization agreements. Other Our exposure to non-current investments, defined as foreclosed real estate and invested assets which are delinquent as to interest and/or principal payments, totaled $56.2 million and $35.5 million on a fair value basis at December 31, 2010 and 2009, respectively. See Notes 3 and 4 of the “Notes to Consolidated Financial Statements” for further discussion of our investments and our derivative financial instruments. Liquidity and Capital Resources Our liquidity requirements are met primarily by cash flows provided from operations, principally in our insurance subsidiaries. Premium and investment income, as well as maturities and sales of invested assets, provide the primary sources of cash. Debt and/or securities offerings provide an additional source of liquidity. Cash is applied to the payment of policy benefits, costs of acquiring new business (principally commissions), operating expenses, and taxes, as well as purchases of new investments. We have established an investment strategy that we believe will provide for adequate cash flows from operations. We attempt to match our asset cash flows and durations with expected liability cash flows and durations to meet the funding requirements of our business. However, deterioration in the credit market may delay our ability to sell our positions in certain of our fixed maturity securities in a timely manner, which may negatively impact our cash flows. Furthermore, if we experience defaults on securities held in the investment portfolios of our insurance subsidiaries, this will negatively impact statutory capital, which could reduce our insurance subsidiaries’ capacity to pay dividends to our holding companies. A reduction in dividends to our holding companies could force us to seek external financing to avoid impairing our ability to pay our stockholder dividends or meet our debt and other payment obligations. 4356_2010AR_Fin_ALL.indd 69 69 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Our policy benefits are primarily in the form of claim payments, and we have minimal exposure to the policy withdrawal risk associated with deposit products such as individual life policies or annuities. A decrease in demand for our insurance products or an increase in the incidence of new claims or the duration of existing claims could negatively impact our cash flows from operations. However, our historical pattern of benefits paid to revenues is consistent, even during cycles of economic downturns, which serves to minimize liquidity risk. We have met all minimum pension funding requirements set forth by ERISA. We made voluntary contributions to our U.S. qualified defined benefit pension plan of $67.0 million and $100.0 million during the first and fourth quarters of 2010, respectively. The fourth quarter of 2010 contribution was made in lieu of our planned 2011 contribution, and we do not anticipate making any additional contributions during 2011. We have estimated our future funding requirements under the Pension Protection Act of 2006 and do not believe that the funding requirements will cause a material adverse effect on our liquidity. We also contribute to our U.K. pension plan sufficient to meet the minimum funding requirement under U.K. legislation. We made contributions of approximately £3.2 million during 2010, and we anticipate that we will make contributions during 2011 of approximately £3.2 million. In September 2010, we issued $400.0 million of senior notes. These notes, due in 2020, bear interest at a fixed-rate of 5.625%. The net proceeds are expected to be used for the repayment of our senior notes due March 2011 and for other general corporate purposes. In May 2010, our board of directors authorized an increase in the quarterly dividend paid on Unum Group’s common stock, from $0.0825 per common share to $0.0925 per common share, effective with our third quarter of 2010 dividend payment to stockholders. In May 2010, our board of directors authorized the repurchase of up to $500.0 million of Unum Group’s common stock, with the pace of repurchase activity to depend upon various factors such as the level of available cash, alternative uses for cash, and our stock price. During 2010, we repurchased 16.4 million shares, at a cost of $356.0 million, including commissions of $0.3 million, under this share repurchase program. The dollar value of shares remaining under this program, which had an expiration date of May 2011, was $144.3 million at December 31, 2010. On February 2, 2011, our board of directors authorized the repurchase of up to $1.0 billion of Unum Group’s common stock, in addition to the amount remaining to be repurchased under the previous authorization discussed above. The $1.0 billion share repurchase program has an expiration date of August 2012. On February 4, 2011, we repurchased 7.1 million shares, at a cost of $200.0 million, using an accelerated repurchase agreement with a financial counterparty. As part of this transaction, we simultaneously entered into a forward contract indexed to the price of Unum Group common stock, which subjects the transaction to a future price adjustment. Under the terms of the repurchase agreement, we may receive, or be required to pay, a price adjustment based on the volume weighted average price of Unum Group common stock during the term of the agreement, less a discount. Any price adjustment payable to us will be settled in shares of Unum Group common stock. Any price adjustment we are required to pay will be settled in either cash or common stock at our option. We expect the price adjustment to settle on or before the completion of the accelerated repurchase agreement in April 2011. The shares repurchased pursuant to the accelerated repurchase agreement completed the $500.0 million repurchase authorization and initiated the $1.0 billion repurchase program. Cash equivalents and marketable securities held at Unum Group and our other intermediate holding companies are a significant source of liquidity for us and were approximately $1.2 billion and $915 million at December 31, 2010 and 2009, respectively. The December 31, 2010 balance was made up primarily of commercial paper, fixed maturity securities with a current average maturity of 2.3 years, and various money-market funds. No significant restrictions exist on our ability to use or access these funds. We believe we hold sufficient resources to meet our liquidity requirements for the next 12 months and that our current level of holding company cash and marketable securities can be utilized to mitigate potential losses from defaults. 70 4356_2010AR_Fin_ALL.indd 70 4/4/11 3:05 PM Unum 2010 Annual Report During 2011, we intend to retain a level of capital in our traditional U.S. insurance subsidiaries such that we maintain a weighted average RBC well above capital adequacy requirements. We also expect Unum Limited to operate above FSA capital adequacy requirements and minimum solvency margins. Unum Limited is expected to adopt new capital requirements and risk management standards under Solvency II effective January 1, 2013. Solvency II standards, which result from a fundamental review of the capital adequacy standards for the European insurance industry, are still being developed and have not yet been adopted. We continue to assess the impact on our capital requirements. Certain of our insurance subsidiaries are also subject to regulation by the Bermuda Monetary Authority (BMA). Last year the BMA initiated a comprehensive review of its insurance regulatory and solvency framework and hopes to complete its assessment during the summer of 2011. It is too early to assess the impact on our insurance subsidiaries, but we may ultimately be subject to new rules regarding capital requirements. See “Capital Requirements” contained herein for additional information. Consolidated Cash Flows Operating Cash Flows Net cash provided by operating activities was $1,196.8 million for the year ended December 31, 2010, compared to $1,237.0 million and $1,326.1 million for 2009 and 2008, respectively. Operating cash flows are primarily attributable to the receipt of premium and investment income, offset by payments of claims, commissions, expenses, and income taxes. Premium income growth is dependent not only on new sales, but on renewals of existing business, renewal price increases, and persistency. Investment income growth is dependent on the growth in the underlying assets supporting our insurance reserves and on the earned yield. The level of commissions and operating expenses is attributable to the level of sales and the first year acquisition expenses associated with new business as well as the maintenance of existing business. The level of paid claims is affected partially by the growth and aging of the block of business and also by the general economy, as previously discussed in the operating results by segment. Operating cash flows for 2010, 2009, and 2008, include pension contributions of approximately $176.9 million, $79.7 million, and $140.9 million, respectively. The fluctuation in the income tax adjustment to reconcile 2009 and 2008 net income to net cash provided by operating activities was due primarily to changes in the deferred tax asset related to the change in the fair value of an embedded derivative in a modified coinsurance arrangement. Investing Cash Flows Investing cash inflows consist primarily of the proceeds from the sales and maturities of investments. Investing cash outflows consist primarily of payments for purchases of investments. Net cash used by investing activities was $1,073.7 million for the year ended December 31, 2010, compared to $1,213.9 million and $424.7 million for 2009 and 2008, respectively. Our sales of available-for-sale securities declined in 2010 relative to 2009. Proceeds from maturities of available-for-sale securities were higher in 2010 compared to 2009 primarily due to a significant increase in bond calls and bond maturities. Proceeds from sales and maturities of available-for-sale securities in 2009 were lower than 2008 primarily due to lower sales of fixed maturity securities, a decrease in bond maturities and bonds that were called at par, and the translation of investment proceeds from our U.K. operations at lower exchange rates. 4356_2010AR_Fin_ALL.indd 71 71 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Proceeds from sales and maturities of other investments decreased in 2010 as compared to 2009 primarily due to a decrease in proceeds from terminations of derivative contracts within our cash flow hedging programs. Proceeds from maturities of commercial mortgage loans were higher in 2010 relative to 2009. Proceeds from sales and maturities of other investments increased in 2009 relative to 2008 primarily due to an increase in sales of other long-term investments and an increase in proceeds from terminations of derivatives within our cash flow hedging programs. This increase was partially offset by a decline in proceeds from commercial mortgage loan maturities and prepayments. Purchases of available-for-sale securities were slightly lower during 2010 relative to 2009. Although investable funds were available for reinvestment due to the increase in proceeds from bond calls and maturities, as previously noted, the deployment of funds was hampered by the lack of available long-term securities which met our investment objectives. Purchases of available-for-sale securities decreased during 2009 relative to 2008. This decrease resulted from fewer funds available for reinvestment as compared to 2008 due to the lower level of proceeds from sales of available-for-sale securities and from the lower exchange rate for translation of purchases within our U.K. operations. Purchases of other investments increased during 2010 relative to 2009 as a result of the purchase of tax credit partnerships, as well as a slight increase in the funding of mortgage loans. Purchases of other investments in 2009 primarily related to mortgage loans. Net purchases of short-term investments increased during 2010 relative to 2009 due to the increase in bond calls and maturities, with the proceeds invested in short-term investments pending the purchase of fixed maturity securities. Net sales of short-term investments decreased during 2009 relative to 2008 due to the sale of investments during 2008 to help fund the $700.0 million accelerated share repurchase agreements executed during 2008, as well as the 2008 transition to floating rate fixed maturity securities in lieu of short-term investments. This decrease in proceeds was partially offset by the transition of our portfolio out of short-term investments into fixed maturity securities during 2009. Proceeds from the acquisition of business in 2008 relate to the Unum UK acquisition of a group long-term disability claims portfolio. Financing Cash Flows Financing cash flows consist primarily of borrowings and repayments of debt, issuance or repurchase of common stock, and dividends paid to stockholders. Net cash used by financing activities was $141.1 million for the year ended December 31, 2010, compared to $1.5 million and $1,049.5 million for 2009 and 2008, respectively. Net short-term debt repayments in 2009 consist of the purchase and retirement of the remaining $132.2 million of our 5.859% notes and the repayment of $58.3 million of reverse repurchase agreements outstanding at December 31, 2008. Net short-term debt repayments in 2008 are comprised of the purchase and retirement of the remaining $175.0 million of our 5.997% senior notes and $17.8 million of our 5.859% notes, less the issuance of $58.3 million of reverse repurchase agreements. During 2010, we received proceeds of $400.0 million, less debt issuance costs of $3.0 million and a debt discount of $0.5 million, from the issuance of $400.0 million of 5.625% senior notes. During 2009, we received proceeds of $350.0 million, less debt issuance costs of $3.2 million, from the issuance of $350.0 million of 7.125% senior notes. Long-term debt repayments include the 2010, 2009, and 2008 principal payments of $10.0 million each year on Tailwind Holdings’ floating rate, senior secured non-recourse notes and the principal payments of $58.3 million, $48.0 million, and $59.3 million, respectively, on Northwind Holdings’ floating rate, senior secured non-recourse notes. Long-term debt repayments also include the purchase and retirement of $10.0 million of our 7.08% medium-term notes in 2010, $1.2 million aggregate principal of our 7.19% medium-term notes and $0.6 million aggregate principal of our 6.75% notes in 2009, and $36.6 million of our 6.85% senior notes in 2008. During 2010, we repurchased approximately 16.4 million shares of Unum Group’s common stock under our $500.0 million share repurchase program, at a cost of $356.0 million. During 2008, we completed a $700.0 million authorized share repurchase program by purchasing 29.9 million shares. See “Debt” contained herein for further information. 72 4356_2010AR_Fin_ALL.indd 72 4/4/11 3:05 PM Unum 2010 Annual Report Cash Available from Subsidiaries Unum Group and certain of its intermediate holding company subsidiaries depend on payments from subsidiaries to pay dividends to stockholders, to pay debt obligations, and/or to pay expenses. These payments by our insurance and non-insurance subsidiaries may take the form of dividends, operating and investment management fees, and/or interest payments on loans from the parent to a subsidiary. Restrictions under applicable state insurance laws limit the amount of dividends that can be paid to a parent company from its insurance subsidiaries in any 12-month period without prior approval by regulatory authorities. For life insurance companies domiciled in the United States, that limitation generally equals, depending on the state of domicile, either ten percent of an insurer’s statutory surplus with respect to policyholders as of the preceding year end or the statutory net gain from operations, excluding realized investment gains and losses, of the preceding year. The payment of dividends to a parent company from its insurance subsidiaries is generally further limited to the amount of unassigned statutory surplus. Unum Group and/or certain of its intermediate holding company subsidiaries may also receive dividends from its United Kingdom- based affiliate, Unum Limited, subject to applicable insurance company regulations and capital guidance in the United Kingdom. Northwind Holdings’ and Tailwind Holdings’ ability to meet their debt payment obligations is dependent upon the receipt of dividends from Northwind Re and Tailwind Re, respectively. The ability of Northwind Re and Tailwind Re to pay dividends to their respective parent companies will depend on their satisfaction of applicable regulatory requirements and on the performance of the business reinsured by Northwind Re and Tailwind Re. The payment of dividends to the parent company from our subsidiaries also requires the approval of the individual subsidiary’s board of directors. The amount available during 2010 for the payment of ordinary dividends from Unum Group’s traditional U.S. insurance subsidiaries was $719.7 million, of which $410.8 million was declared and paid. The amount available during 2010 from Unum Limited was £198.5 million, of which £50.0 million was declared and paid. During 2010, Tailwind Re and Northwind Re paid dividends of $18.8 million and $58.9 million to Tailwind Holdings and Northwind Holdings, respectively. Although we may not utilize the entire amount of available dividends, based on the restrictions under current law, $622.3 million is available during 2011 for the payment of ordinary dividends to Unum Group from its traditional U.S. insurance subsidiaries, which excludes Northwind Re and Tailwind Re, our special purpose financial captive insurance companies. Approximately £207.5 million is available for the payment of dividends from Unum Limited during 2011, subject to regulatory approval. However, it is unlikely that we will utilize the entire amount available during 2011. Unum Group’s RBC ratio for its traditional U.S. insurance subsidiaries, calculated on a weighted average basis using the NAIC Company Action Level formula, was approximately 398 percent at the end of 2010, with the individual RBC ratios for Unum Group’s principal traditional U.S. insurance subsidiaries all in excess of 300 percent. The individual RBC ratios for Northwind Re and Tailwind Re are calculated using the NAIC Company Action Level formula and have target levels of 200 percent. The RBC ratios for Northwind Re and Tailwind Re each exceeded the 200 percent target level at the end of 2010. The individual RBC ratio for each of our insurance subsidiaries is above the range that would require state regulatory action. During 2008, Unum Group received $100.0 million from an insurance subsidiary for the repayment of a surplus debenture issued to Unum Group in 1997 with a maturity date of October 2027. The ability of Unum Group and certain of its intermediate holding company subsidiaries to continue to receive dividends from their insurance subsidiaries generally depends on the level of earnings of those insurance subsidiaries and additional factors such as RBC ratios and FSA capital adequacy requirements, funding growth objectives at an affiliate level, and maintaining appropriate capital adequacy ratios to support desired ratings. Insurance regulatory restrictions do not limit the amount of dividends available for distribution from non- insurance subsidiaries except where the non-insurance subsidiaries are held directly or indirectly by an insurance subsidiary and only indirectly by Unum Group. We intend to retain a level of capital in our traditional U.S. insurance subsidiaries such that we maintain a weighted average risk-based capital above capital adequacy requirements. We also expect Unum Limited to operate above FSA capital adequacy requirements and minimum solvency margins. 4356_2010AR_Fin_ALL.indd 73 73 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Debt At December 31, 2010, we had long-term debt, including senior secured notes and junior subordinated debt securities, totaling $2,631.3 million and short-term debt of $225.1 million. Short-term debt consisted of the 7.625% senior notes due March 2011. Our leverage ratio, when calculated using consolidated debt to total consolidated capital, was 25.9 percent at December 31, 2010 compared to 24.8 percent at December 31, 2009, reflecting the issuance of $400.0 million of senior notes during the third quarter of 2010. Our leverage ratio, when calculated excluding the non-recourse debt and associated capital of Tailwind Holdings and Northwind Holdings, was 22.8 percent at December 31, 2010 compared to 20.5 percent at the end of 2009. Leverage is measured as total debt to total capital, which we define as total long-term and short-term debt plus stockholders’ equity, excluding the net unrealized gain or loss on securities and the net gain or loss on cash flow hedges. We believe that a leverage ratio which excludes the net unrealized gains and losses on securities and the net gain or loss on cash flow hedges, both of which tend to fluctuate depending on market conditions and general economic trends, and which also excludes the non-recourse debt and associated capital of Tailwind Holdings and Northwind Holdings is a better indicator of our ability to meet our financial obligations. We monitor our compliance with our debt covenants. There are no significant financial covenants associated with any of our outstanding debt obligations. We remain in compliance with all debt covenants and have not observed any current trends that would cause a breach of any debt covenants. Purchases and Retirement of Debt In 2010, we purchased and retired $10.0 million of our 7.08% medium-term notes due 2024. In 2009, we purchased and retired the remaining $132.2 million of our 5.859% senior notes due May 2009, $1.2 million aggregate principal of our 7.19% medium-term notes due 2028, and $0.6 million aggregate principal of our 6.75% notes due 2028. We also repaid $58.3 million of reverse repurchase agreements outstanding at December 31, 2008. In 2008, we retired the remaining $175.0 million of our 5.997% senior notes due May 2008. We also purchased and retired $36.6 million of our 6.85% senior debentures due 2015 and $17.8 million of our 5.859% senior notes due May 2009. During 2010, 2009, and 2008, Northwind Holdings made principal payments of $58.3 million, $48.0 million and $59.3 million, respectively, on its floating rate, senior secured non-recourse notes due 2037. During 2010, 2009, and 2008, Tailwind Holdings made principal payments of $10.0 million each year on its floating rate, senior secured non-recourse notes due 2036. Issuance of Debt In 2010, we issued $400.0 million of unsecured senior notes in a public offering. These notes, due in 2020, bear interest at a fixed rate of 5.625% and are payable semi-annually. The notes are callable at or above par and rank equally in right of payment with all of our other unsecured and unsubordinated debt. In addition, these notes are effectively subordinated to any indebtedness of our subsidiaries. In 2009, we issued $350.0 million of unsecured senior notes in a public offering. These notes, due in 2016, bear interest at a fixed rate of 7.125% and are payable semi-annually. The notes are callable at or above par and rank equally in right of payment with all of our other unsecured and unsubordinated debt. In 2007, Northwind Holdings issued $800.0 million floating rate, insured, senior, secured notes, due 2037, in a private offering. Recourse for the payment of principal, interest, and other amounts due on the notes will be limited to the assets of Northwind Holdings, consisting primarily of the stock of its sole subsidiary Northwind Re, a Vermont special purpose financial captive insurance company. Northwind Holdings’ ability to meet its payment obligations under the notes will be dependent principally upon its receipt of dividends from Northwind Re. The ability of Northwind Re to pay dividends to Northwind Holdings will depend on its satisfaction of applicable regulatory requirements and on the performance of the reinsured claims of Provident, Paul Revere and Unum America (the ceding insurers) reinsured by Northwind Re. None of Unum Group, the ceding insurers, Northwind Re or any other affiliate of Northwind Holdings is an obligor or guarantor on the notes. The balance outstanding on these notes was $634.4 million at December 31, 2010. 74 4356_2010AR_Fin_ALL.indd 74 4/4/11 3:05 PM Unum 2010 Annual Report In 2006, Tailwind Holdings issued $130.0 million floating rate, insured, senior, secured notes, due 2036, in a private offering. Recourse for the payment of principal, interest, and other amounts due on the notes will be limited to the assets of Tailwind Holdings, consisting primarily of the stock of its sole subsidiary Tailwind Re, a South Carolina special purpose financial captive insurance company. Tailwind Holdings’ ability to meet its payment obligations under the notes will be dependent principally upon its receipt of dividends from Tailwind Re. The ability of Tailwind Re to pay dividends to Tailwind Holdings will depend on its satisfaction of applicable regulatory requirements and on the performance of the reinsured claims of Unum America reinsured by Tailwind Re. None of Unum Group, Unum America, Tailwind Re or any other affiliate of Tailwind Holdings is an obligor or guarantor on the notes. The balance outstanding on these notes was $82.5 million at December 31, 2010. In 2005, Unum Group repatriated $454.8 million in unremitted foreign earnings from its U.K. subsidiaries, and as part of its repatriation plan, UnumProvident Finance Company plc, a wholly-owned subsidiary of Unum Group, issued $400.0 million of 6.85% senior debentures, due 2015, in a private offering. The debentures are fully and unconditionally guaranteed by Unum Group. The aggregate principal amount outstanding was $296.9 million at December 31, 2010. In 2002, Unum Group completed two long-term offerings, issuing $250.0 million of 7.375% senior debentures due 2032 and $150.0 million of 7.25% public income notes due 2032. The public income notes were called and retired in 2007. The 7.375% notes have an aggregate principal amount outstanding of $39.5 million at December 31, 2010. In 2001, Unum Group issued $575.0 million of 7.625% senior notes due March 2011. The aggregate principal amount outstanding was $225.1 million at December 31, 2010. In 1998, Unum Group completed public offerings of $200.0 million of 7.25% senior notes due 2028, $200.0 million of 7.0% senior notes due 2018, and $250.0 million of 6.75% senior notes due 2028. None of these amounts have been reduced other than the 6.75% notes, which have an aggregate principal amount outstanding of $165.8 million at December 31, 2010. In 1998, Provident Financing Trust I (the trust) issued $300.0 million of 7.405% capital securities in a public offering. These capital securities, which mature in 2038, are fully and unconditionally guaranteed by Unum Group, have a liquidation value of $1,000 per capital security, and have a mandatory redemption feature under certain circumstances. Unum Group issued 7.405% junior subordinated deferrable interest debentures, which mature in 2038, to the trust in connection with the capital securities offering. The securities issued by the trust have an aggregate principal amount outstanding of $226.5 million at December 31, 2010. Unum Group has medium-term notes with an aggregate principal amount outstanding of $50.8 million at December 31, 2010 which were initially issued in three separate series in 1990, 1993, and 1996, pursuant to an indenture dated September 15, 1990. The notes are fixed maturity rate notes with fixed maturity dates ranging between nine months to thirty years from the issuance date. Interest and Debt Expense Interest paid on long-term and short-term debt and related securities during 2010, 2009, and 2008 was $140.7 million, $122.0 million, and $157.3 million, respectively. Shelf Registration We have a shelf registration, which became effective in December 2008, with the Securities and Exchange Commission to issue various types of securities, including common stock, preferred stock, debt securities, depository shares, stock purchase contracts, units and warrants, or preferred securities of wholly-owned finance trusts. As stated previously, we issued $350.0 million and $400.0 million of senior notes against our open shelf registration on September 30, 2009, and September 15, 2010, respectively. The shelf registration enables us to raise funds from the offering of any individual security covered by the shelf registration as well as any combination thereof, subject to market conditions and our capital needs. See Note 7 of the “Notes to Consolidated Financial Statements” for additional information. 4356_2010AR_Fin_ALL.indd 75 75 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Commitments The following table summarizes contractual obligations and our reinsurance recoverable by period as of December 31, 2010 (in millions of dollars): Payments Due Short-term Debt Long-term Debt Policyholder Liabilities Pensions and Other Postretirement Benefits Miscellaneous Liabilities Operating Leases Purchase Obligations Total Receipts Due Total In 1 Year or Less After 1 Year After 3 Years up to 3 Years up to 5 Years After 5 Years $ 228.0 $ 228.0 $ — $ — $ — 4,560.9 40,278.1 1,957.0 745.9 220.1 377.2 138.0 4,309.1 23.4 692.6 25.8 286.6 283.5 6,582.7 69.4 12.8 48.0 82.4 587.9 5,092.3 128.2 8.0 35.4 5.4 3,551.5 24,294.0 1,736.0 32.5 110.9 2.8 $48,367.2 $5,703.5 $7,078.8 $5,857.2 $29,727.7 Reinsurance Recoverable $ 7,529.6 $ 303.6 $ 565.1 $ 553.6 $ 6,107.3 Excluded from the preceding table are tax liabilities of approximately $114.0 million for which we are unable to make reasonably reliable estimates of the period of potential cash settlements, if any, with taxing authorities. It is possible that during 2011 we may reach a final settlement with the Internal Revenue Service concerning audit adjustments for certain tax years, and if so, it is reasonably possible that our liability for unrecognized tax benefits could decrease within 12 months by $0 to $40.0 million. See Note 6 of the “Notes to Consolidated Financial Statements” for additional information. Short-term and long-term debt includes contractual principal and interest payments and therefore exceeds the amount shown in the consolidated balance sheets. See Note 7 of the “Notes to Consolidated Financial Statements” for additional information. Policyholder liability maturities and the related reinsurance recoverable represent the projected payout of the current in-force policyholder liabilities and the expected cash inflows from reinsurers for liabilities ceded and therefore incorporate uncertainties as to the timing and amount of claim payments. We utilize extensive liability modeling to project future cash flows from the in-force business. The primary assumptions used to project future cash flows are claim incidence rates for mortality and morbidity, claim resolution rates, persistency rates, and interest rates. These cash flows are discounted to determine the current value of the projected claim payments. The timing and amount of payments on policyholder liabilities may vary significantly from the projections above. See our previous discussion of asset and liability management under “Investments” contained herein and Note 1 of the “Notes to Consolidated Financial Statements” for additional information. Pensions and other postretirement benefit obligations include our defined benefit pension and postretirement plans for our employees, including non-qualified pension plans. Pension plan obligations, other than the non-qualified plans, represent our contributions to the pension plans. Amounts in the one year or less category equal our planned contributions within the next 12 months. The remaining years’ contributions are projected based on the expected future contributions as required under ERISA. Non-qualified pension plan and other postretirement benefit obligations represent the expected benefit payments related to these plans. The pensions and other postretirement benefit projections are not discounted with respect to interest and therefore exceed the amount recorded in the consolidated balance sheets. See Note 8 of the “Notes to Consolidated Financial Statements” and “Critical Accounting Estimates” contained herein for additional information. 76 4356_2010AR_Fin_ALL.indd 76 4/4/11 3:05 PM Unum 2010 Annual Report Miscellaneous liabilities include commissions due and accrued, deferred compensation liabilities, state premium taxes payable, amounts due to reinsurance companies, accounts payable, obligations to return unrestricted cash collateral to our derivatives counterparties, and various other liabilities that represent contractual obligations. Obligations where the timing of the payment was uncertain are included in the one year or less category. See Note 4 of the “Notes to Consolidated Financial Statements” for additional information on our derivatives. We have commitments of $169.9 million to fund certain tax credit partnerships. These commitments, which are represented in the purchase obligations line on the preceding schedule, are legally binding and will be funded over the next several years. Off-Balance Sheet Arrangements As noted in the preceding commitments table, we have operating lease commitments totaling $220.1 million at December 31, 2010. Operating leases include noncancelable obligations on certain office space, equipment, and software. During 2010, we signed a noncancelable operating lease for office space that will commence in 2013. The lease will expire in 2029, but we will have a renewal option through 2044. The projected lease payments, along with commitments of $0.8 million to fund leasehold improvements, are included in the preceding commitments table. Purchase obligations include off-balance sheet commitments of $147.7 million to fund certain of our investments in private placement securities, commercial mortgage loans, and private equity partnerships. These are shown in the preceding table based on the expiration date of the commitments. The funds will be due upon satisfaction of contractual notice from the partnership trustee or issuer of the private placement securities. The amounts may or may not be funded. Also included are noncancelable obligations with outside parties for computer data processing services and related functions and software maintenance agreements. The aggregate obligation remaining under these agreements was $35.8 million at December 31, 2010. As part of our regular investing strategy, we receive collateral from unaffiliated third parties through transactions which include both securities lending and also short-term agreements to purchase securities with the agreement to resell them at a later specified date. For both types of transactions, we require that a minimum of 102 percent of the fair value of the securities loaned or securities purchased under repurchase agreements be maintained as collateral. Generally, cash is received as collateral under these agreements. In the event that securities are received as collateral, we are not permitted to sell or re-post them. We also post our fixed maturity securities as collateral to unaffiliated third parties through transactions including both securities lending and also short-term agreements to sell securities with the agreement to repurchase them at a later specified date. At December 31, 2010, we had no fixed maturity securities posted as collateral to third parties under these programs. To help limit the credit exposure of the derivatives, we enter into master netting agreements with our counterparties whereby contracts in a gain position can be offset against contracts in a loss position. We also typically enter into bilateral, cross-collateralization agreements with our counterparties to help limit the credit exposure of the derivatives. These agreements require the counterparty in a loss position to submit acceptable collateral with the other counterparty in the event the net loss position meets or exceeds an agreed upon amount. Our current credit exposure on derivatives, which is limited to the value of those contracts in a net gain position less collateral held, was $14.8 million at December 31, 2010. We post fixed maturity securities as collateral to our counterparties rather than cash. The carrying value of fixed maturity securities posted as collateral to our counterparties was $158.8 million at December 31, 2010. Our derivatives counterparties have posted non-cash collateral in various segregated custody accounts to which we have a security interest in the event of counterparty default. This collateral, which is not reflected in the preceding table, had a market value of $17.3 million at December 31, 2010. 4356_2010AR_Fin_ALL.indd 77 77 4/4/11 3:05 PM Management’s Discussion and Analysis of Financial Condition and Results of Operations Unum 2010 Transfers of Financial Assets To manage our cash position more efficiently, we enter into repurchase agreements with unaffiliated financial institutions. We generally use repurchase agreements as a means to finance the purchase of invested assets or for short-term general business purposes until projected cash flows become available from our operations or existing investments. Our repurchase agreements are typically outstanding for less than 30 days. We post collateral through our repurchase agreement transactions whereby the counterparty commits to purchase securities with the agreement to resell them to us at a later, specified date. The fair value of collateral posted is generally 102 percent of the cash received. As previously noted, our investment policy also permits us to lend fixed maturity securities to unaffiliated financial institutions in short-term securities lending transactions, which increase our investment income with minimal risk. We had no securities lending transactions during 2010. We account for all of our securities lending transactions and repurchase agreements as collateralized financings. We had no repurchase agreements outstanding at December 31, 2010. The average balance during 2010 was $39.4 million, and the maximum amount outstanding at any month end was $150.4 million. Our use of repurchase agreements can fluctuate during any given period, depending on our liquidity position, the availability of long-term investments that meet our purchasing criteria, and our general business needs. Ratings AM Best, Fitch, Moody’s, and 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. We compete based in part on the financial strength ratings provided by rating agencies. A downgrade of our financial strength ratings can be expected to adversely affect us and could potentially, among other things, adversely affect our relationships with distributors of our products and services and retention of our sales force, negatively impact persistency and new sales, particularly large case group sales and individual sales, and generally adversely affect our ability to compete. A downgrade in the issuer credit rating assigned to Unum Group can be expected to adversely affect our cost of capital or our ability to raise additional capital. The table below reflects the issuer credit ratings for Unum Group and the financial strength ratings for each of our traditional insurance subsidiaries as of the date of this filing.

A significant component of our communications involves our annual review meeting with each of the four agencies. We hold other meetings throughout the year regarding our business, including, but not limited to, quarterly updates. On February 12, 2010, Fitch upgraded its ratings of Unum Group and its operating subsidiaries to BBB and A, respectively, and changed the outlook for the Company to “stable.” On March 8, 2010, AM Best affirmed its ratings of Unum Group and all of its operating subsidiaries, with the exception of Paul Revere Variable, and revised the outlook for the Company to “positive.” The rating of Paul Revere Variable was lowered to B++ due to the continued decline in this subsidiary’s closed block of business. On May 12, 2010, Moody’s upgraded the credit ratings of Unum Group’s senior debt to Baa3 from Ba1 and the financial strength ratings of each rated individual insurance subsidiary to A3 from Baa1. Moody’s maintained the outlook for the Company as “stable.” On January 26, 2011, AM Best upgraded its ratings of Unum Group and its operating subsidiaries to bbb and A, respectively, with the exception of Paul Revere Variable which retained its B++ rating, and revised the outlook for the Company and its subsidiaries to “stable.” There have been no other changes in any of the rating agencies’ outlook statements or ratings during 2010 or prior to the date of this filing. Agency ratings are not directed toward the holders of our securities and are not recommendations to buy, sell, or hold our securities. Each rating is subject to revision or withdrawal at any time by the assigning rating organization, and each rating should be regarded as an independent assessment, not conditional on any other rating. Given the dynamic nature of the ratings process, changes by these or other rating agencies may or may not occur in the near-term. Based on our ongoing dialogue with the rating agencies concerning our improved insurance risk profile, our financial flexibility, our operating performance, and the quality of our investment portfolio, we do not expect any negative actions from any of the four rating agencies related to either Unum Group’s current issuer credit ratings or the financial strength ratings of its insurance subsidiaries. However, in the event that we are unable to meet the rating agency specific guideline values to maintain our current ratings, including but not limited to maintenance of our capital management metrics at the threshold values stated and maintenance of our financial flexibility and operational consistency, we could be placed on a negative credit watch, with a potential for a downgrade to both our issuer credit ratings and our financial strength ratings. See “Ratings” contained in Item 1 and “Risk Factors” contained in Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2010 for further discussion. 4356_2010AR_Fin_ALL.indd 79 79 4/4/11 3:05 PM Quantitative and Qualitative Disclosures About Market Risk Unum 2010 We are subject to various market risk exposures, including interest rate risk and foreign exchange rate risk. The following discussion regarding our risk management activities includes forward-looking statements that involve risk and uncertainties. Estimates of future performance and economic conditions are reflected assuming certain changes in market rates and prices were to occur (sensitivity analysis). Caution should be used in evaluating our overall market risk from the information presented below, as actual results may differ. See “Investments” contained herein and Notes 2, 3, and 4 of the “Notes to Consolidated Financial Statements” for further discussions of the qualitative aspects of market risk, including derivative financial instrument activity. Interest Rate Risk Our exposure to interest rate changes results from our holdings of financial instruments such as fixed rate investments, derivatives, and interest-sensitive liabilities. Fixed rate investments include fixed maturity securities, mortgage loans, policy loans, and short-term investments. Fixed maturity securities include U.S. and foreign government bonds, securities issued by government agencies, corporate bonds, mortgage-backed securities, and redeemable preferred stock, all of which are subject to risk resulting from interest rate fluctuations. Certain of our financial instruments, fixed maturity securities and derivatives, are carried at fair value in our consolidated balance sheets. The fair value of these financial instruments may be adversely affected by changes in interest rates. A rise in interest rates may increase the net unrealized loss related to these financial instruments, but may improve our ability to earn higher rates of return on new purchases of fixed maturity securities. Conversely, a decline in interest rates may decrease the net unrealized loss, but new securities may be purchased at lower rates of return. Although changes in fair value of fixed maturity securities and derivatives due to changes in interest rates may impact amounts reported in our consolidated balance sheets, these changes will not cause an economic gain or loss unless we sell investments, terminate derivative positions, determine that an investment is other than temporarily impaired, or determine that a derivative instrument is no longer an effective hedge. Other fixed rate investments, such as mortgage loans and policy loans, are carried at amortized cost and unpaid balances, respectively, rather than fair value in our consolidated balance sheets. These investments may have fair values substantially higher or lower than the carrying values reflected in our balance sheets. A change in interest rates could impact our financial position if we sold our mortgage loan investments at times of low market value. A change in interest rates would not impact our financial position at repayment of policy loans, as ultimately the cash surrender values or death benefits would be reduced for the carrying value of any outstanding policy loans. Carrying amounts for short-term investments approximate fair value, and we believe we have minimal interest rate risk exposure from these investments. We believe that the risk of being forced to liquidate investments or terminate derivative positions is minimal, primarily due to the level of capital at our insurance subsidiaries, the level of cash and marketable securities at our holding companies, and our investment strategy which we believe provides for adequate cash flows to meet the funding requirements of our business. We may in certain circumstances, however, need to sell investments due to changes in regulatory or capital requirements, changes in tax laws, rating agency decisions, and/or unexpected changes in liquidity needs. 80 4356_2010AR_Fin_ALL.indd 80 4/4/11 3:05 PM Unum 2010 Annual Report Although the majority of our liabilities related to insurance contracts are not interest rate sensitive and we therefore have minimal exposure to policy withdrawal risk, the fair values of liabilities under all insurance contracts are taken into consideration in our overall management of interest rate risk, which minimizes exposure to changing interest rates through the matching of investment cash flows with amounts due under insurance contracts. Changes in interest rates and individuals’ behavior affect the amount and timing of asset and liability cash flows. We actively manage our asset and liability cash flow match and our asset and liability duration match to mitigate interest rate risk. Due to the long duration of our long-term care product, we may be unable to purchase appropriate assets with cash flows and durations such that the timing and/or amount of our investment cash flows may not match those of our maturing liabilities. Sustained periods of low interest rates could result in lower than expected profitability or increases in reserves. We model and test asset and liability portfolios to improve interest rate risk management and net yields. Testing the asset and liability portfolios under various interest rate and economic scenarios allows us to choose what we believe to be the most appropriate investment strategy, as well as to prepare for disadvantageous outcomes. This analysis is the precursor to our activities in derivative financial instruments. We use current and forward interest rate swaps, options on forward interest rate swaps, and forward treasury locks to hedge interest rate risks and to match asset durations and cash flows with corresponding liabilities. Short-term and long-term debt are not carried at fair value in our consolidated balance sheets. If we modify or replace existing short- term or long-term debt instruments at current market rates, we may incur a gain or loss on the transaction. We believe our debt-related risk to changes in interest rates is relatively minimal. In the near term, we expect that our need for external financing is small, but changes in our business could increase our need. We measure our financial instruments’ market risk related to changes in interest rates using a sensitivity analysis. This analysis estimates potential changes in fair values as of December 31, 2010 and 2009 based on a hypothetical immediate increase of 100 basis points in interest rates from year end levels. The selection of a 100 basis point immediate parallel change in interest rates should not be construed as our prediction of future market events, but only as an illustration of the potential effect of such an event. 4356_2010AR_Fin_ALL.indd 81 81 4/4/11 3:05 PM Quantitative and Qualitative Disclosures About Market Risk Unum 2010 The hypothetical potential changes in fair value of our financial instruments at December 31, 2010 and 2009 are shown as follows: (in millions of dollars) Assets Fixed Maturity Securities (1) Mortgage Loans Policy Loans, Net of Reinsurance Ceded Liabilities Unrealized Adjustment to Reserves, Net of Reinsurance Ceded and Other (2) Short-term Debt Long-term Debt Derivatives (1) Swaps Embedded Derivative in Modified Coinsurance Arrangement (in millions of dollars) Assets Fixed Maturity Securities (1) Mortgage Loans Policy Loans, Net of Reinsurance Ceded Liabilities Unrealized Adjustment to Reserves, Net of Reinsurance Ceded and Other (2) Long-term Debt Derivatives (1) Swaps Forwards Embedded Derivative in Modified Coinsurance Arrangement December 31, 2010 Notional Hypothetical Amount of Derivatives Fair Value FV + 100 BP Change in FV $40,035.6 $36,576.1 $(3,459.5) 1,685.4 253.9 1,609.5 239.9 (75.9) (14.0) $ (2,993.6) $ (631.6) $ 2,362.0 (226.8) (2,483.8) (226.4) (2,358.3) 0.4 125.5 $1,681.9 $ (100.5) $ (190.6) $ (90.1) (96.3) (105.4) (9.1) December 31, 2009 Notional Hypothetical Amount of Derivatives Fair Value FV + 100 BP Change in FV $37,914.4 $34,930.8 $(2,983.6) 1,402.5 232.0 1,336.4 219.9 (66.1) (12.1) $ (1,541.7) $ 113.3 $ 1,655.0 (2,296.0) (2,204.1) 91.9 $ (63.1) $ (87.9) $ (24.8) (0.4) (0.2) (117.4) (121.5) 0.2 (4.1) $1,615.9 4.8 (1) These assets and liabilities are carried at fair value in our consolidated balance sheets. Changes in fair value resulting from changes in interest rates may affect the fair value at which the item is reported in our consolidated balance sheets with a corresponding offsetting change reported in other comprehensive income or loss, net of deferred taxes. (2) The adjustment to reserves and other for unrealized investment gains and losses reflects the adjustments to deferred acquisition costs and policyholder liabilities that would be necessary if the unrealized investment gains and losses related to the fixed maturity securities and derivatives had been realized. Changes in this adjustment are also reported as a component of other comprehensive income or loss, net of deferred taxes. 82 4356_2010AR_Fin_ALL.indd 82 4/4/11 3:05 PM Unum 2010 Annual Report The effect of a change in interest rates on asset prices was determined using a duration implied methodology for corporate bonds and government and government agency securities whereby the duration of each security was used to estimate the change in price for the security assuming an increase of 100 basis points in interest rates. The effect of a change in interest rates on the mortgage-backed securities was estimated using a mortgage analytic system which takes into account the impact of changing prepayment speeds resulting from a 100 basis point increase in interest rates on the change in price of the mortgage-backed securities. These hypothetical prices were compared to the actual prices for the period to compute the overall change in market value. The changes in the fair values shown in the chart above for all other items were determined using discounted cash flows analyses. Because we actively manage our investments and liabilities, actual changes could be less than those estimated above. Foreign Currency Risk The functional currency of our U.K. operations is the British pound sterling. We are exposed to foreign currency risk arising from fluctuations in the British pound sterling to U.S. dollar exchange rates primarily as they relate to the translation of the financial results of our U.K. operations. Fluctuations in the pound to dollar exchange rate have an effect on our reported financial results. We do not hedge against the possible impact of this risk. Because we do not actually convert pounds into dollars except for a limited number of transactions, we view foreign currency translation as a financial reporting issue and not a reflection of operations or profitability in the U.K. Assuming the pound to dollar exchange rate decreased 10 percent from the December 31, 2010 and 2009 levels, stockholders’ equity as reported in U.S. dollars as of and for the periods then ended would have been lower by approximately $106.0 million and $98.6 million, respectively. Assuming the pound to dollar average exchange rate decreased 10 percent from the actual average exchange rates for 2010 and 2009, segment operating income, which excludes net realized investment gains and losses and income tax, as reported in U.S. dollars would have decreased approximately $22.5 million and $27.1 million, respectively, for the years then ended. Dividends paid by Unum Limited are generally held at our U.K. finance subsidiary. If these funds are repatriated to our U.S. holding company, we would at that time be subject to foreign currency risk as the value of the dividend, when converted into U.S. dollars, would be dependent upon the foreign exchange rate at the time of conversion. We are also exposed to foreign currency risk related to certain foreign investment securities denominated in local currencies and U.S. dollar-denominated debt issued by one of our U.K. subsidiaries. We use current and forward currency swaps and currency forward contracts to hedge or minimize the foreign exchange risk associated with these instruments. See “Unum UK Segment” contained herein for further information concerning foreign currency translation. Risk Management As an insurer, we are in the business of risk management. Effectively taking and managing risks is essential to the success of our Company. To facilitate this effort, we have an Enterprise Risk Management (ERM) program. Our ERM program strives to: • Identify, measure, mitigate, and report on our risk positions and exposures, including notable risk events; • Assess material risks, including how they affect us, how individual risks interrelate, and how management addresses these risks; • Practice strong risk management, including diversification across and within business units and systematic limit monitoring; • Identify emerging risks and analyze how material future risks might affect us; • Fulfill regulatory, rating agency, and governance objectives; and • Maintain our risk appetite policy and report against its tolerance and limits. 4356_2010AR_Fin_ALL.indd 83 83 4/4/11 3:05 PM Quantitative and Qualitative Disclosures About Market Risk Unum 2010 Through adherence to these objectives, we believe we are better positioned to fulfill our corporate mission, improve and protect stockholder value, and reduce reputational risk. Our approach to risk management is defined by these fundamental principles: • Our risk management strategy begins with our business strategy. We are a specialty insurance carrier focused on providing benefits through employer-sponsored plans. We have market leadership positions in the product lines we offer and more than 160 years of experience. This combination of focused expertise and deep experience is the foundation of our approach to risk management. • Risk management cannot be successful in a vacuum; it needs to be embedded in daily decision-making throughout the organization. Unum Group’s board members and our senior leaders clearly acknowledge that risk management is critical to our Company’s long- term success, and this theme cascades through the work of risk committees and the management team. Additionally, we believe the individual and collective decisions of our employees play a key role in successfully managing our overall risk profile. • We closely monitor emerging risks, adjust our strategies as appropriate, and hold capital levels which provide financial flexibility. We use qualitative and quantitative approaches to identify emerging risks and develop mitigating strategies to limit our exposure to existing and potential risks. We utilize stress testing and scenario analysis to shape our business, financial, and strategic planning activities. For example, stress testing of our capital and liquidity management strategies enables us to identify areas of high exposure, assess mitigating actions, develop contingency plans, and guide decisions around our capital and liquidity levels. In addition, scenario analysis is used as input in the development of our business and strategic planning processes. Risk Committee Structure and Role We have a “pyramid” risk committee structure in place to govern our ERM process. Unum Group’s board of directors has an active role, as a whole and also at the committee level, in overseeing management of our risks. The board is responsible for managing strategic risk and regularly reviews information regarding our capital, liquidity, and operations, as well as the risks associated with each, and receives an enterprise risk management report from our chief risk officer at least annually, and usually more frequently. The audit committee is responsible for oversight of our risk management process, financial risk, operational risk, and any other risk not specifically assigned to another committee. The chief risk officer provides a report on our risk and risk management to the audit committee at least quarterly. The finance committee is responsible for oversight of risks associated with investments and related financial matters. The human capital committee is responsible for overseeing the management of risks relating to our compensation plans and programs; in connection with this oversight it receives an analysis from the chief risk officer with respect to these risks. The regulatory compliance committee oversees management of risks related to regulatory, compliance, policy, and legal matters, both current and emerging and whether of a local, state, federal, or international nature. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire board of directors is regularly informed through committee reports about such risks in addition to the risk information it receives directly. An executive risk management committee is responsible for overseeing our enterprise-wide risk management program. The chief risk officer, who is a member of the executive risk management committee, has primary responsibility for our ERM program and is supported by a corporate risk committee and by the risk committees of the three primary operating segments that comprise Unum Group. Operating segment risk committees for Unum US, Unum UK, and Colonial Life oversee risk specific to their business. These committees are responsible for identifying, measuring, reporting, and managing insurance and operational risks within their respective areas, consistent with corporate guidance. The corporate risk committee oversees the operational, investment, and capital management subcommittees and reviews risk on a corporate level. Market and credit risk are jointly managed by the investment committee and the asset liability committee. The capital management committee is responsible for monitoring and planning capital allocation, financing, and liquidity. In addition to the formal communication channels included in the risk committee structure, we provide ways for employees to report risk directly to the chief risk officer, and we educate employees on Company risks. 84 4356_2010AR_Fin_ALL.indd 84 4/4/11 3:05 PM Unum 2010 Annual Report Governance, Risk, and Compliance We employ a decentralized risk management model under which risk-based decisions are made daily on a local level. To achieve long-term success, we believe risk management must be the responsibility of all employees. We strive for a culture of accountability, risk management, and strict compliance, and we believe these values allow our employees to feel comfortable identifying issues as well as taking ownership for addressing potential problems. The recent recession and financial sector problems have reinforced the importance of effective governance, risk management, and compliance. We rely on four complementary functions. • Internal controls provide reasonable assurance that there are controls in place to prevent and detect a material misstatement in our financial reporting; • Internal audits assess the effectiveness of controls for operational business processes and monitor compliance with internal policies and procedures; • Our compliance organization seeks to ensure compliance with laws and regulations and is responsible for directing our ethics program and privacy efforts; and • The ERM program serves as an umbrella and takes a holistic view of risks and risk management efforts across the enterprise. These groups work closely together to align their plans, activities, and efforts toward the common goal of effective governance, risk, and compliance. 4356_2010AR_Fin_ALL.indd 85 85 4/4/11 3:05 PM Consolidated Balance Sheets (in millions of dollars) Assets Investments Unum 2010 December 31 2010 2009 Fixed Maturity Securities — at fair value (amortized cost: $36,546.6; $35,905.4) $40,035.6 $37,914.4 Mortgage Loans Policy Loans Other Long-term Investments Short-term Investments Total Investments Other Assets Cash and Bank Deposits Accounts and Premiums Receivable Reinsurance Recoverable Accrued Investment Income Deferred Acquisition Costs Goodwill Property and Equipment Other Assets 1,516.8 2,996.1 529.3 1,163.1 1,404.0 2,878.0 233.5 865.5 46,240.9 43,295.4 53.6 1,665.8 4,827.9 669.8 2,521.1 201.2 476.8 650.6 71.6 1,732.4 4,996.9 642.5 2,482.5 201.6 443.5 610.6 Total Assets See notes to consolidated financial statements. $57,307.7 $54,477.0 86 4356_2010AR_Fin_ALL.indd 86 4/4/11 3:05 PM (in millions of dollars) Liabilities and Stockholders’ Equity Liabilities Policy and Contract Benefits Reserves for Future Policy and Contract Benefits Unearned Premiums Other Policyholders’ Funds Income Tax Payable Deferred Income Tax Short-term Debt Long-term Debt Other Liabilities Total Liabilities Commitments and Contingent Liabilities — Note 13 Stockholders’ Equity Common Stock, $0.10 par Authorized: 725,000,000 shares Issued: 364,842,919 and 363,638,314 shares Additional Paid-in Capital Accumulated Other Comprehensive Income (Loss) Net Unrealized Gain on Securities Not Other-Than-Temporarily Impaired Net Unrealized Gain on Securities Other-Than-Temporarily Impaired Net Gain on Cash Flow Hedges Foreign Currency Translation Adjustment Unrecognized Pension and Postretirement Benefit Costs Retained Earnings Treasury Stock — at cost: 48,269,467 and 31,829,067 shares Total Stockholders’ Equity Total Liabilities and Stockholders’ Equity See notes to consolidated financial statements.

Significant Accounting Policies Basis of Presentation: The accompanying consolidated financial statements of Unum Group and its subsidiaries (the Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). Such accounting principles differ from statutory accounting principles (see Note 14). Intercompany transactions have been eliminated. In connection with our preparation of the consolidated financial statements, we evaluated events that occurred subsequent to December 31, 2010, for recognition or disclosure in our financial statements and notes to our financial statements. Description of Business: We are the largest provider of group and individual disability products in the United States and the United Kingdom. We also provide a complementary portfolio of other insurance products, including long-term care insurance, life insurance, employer- and employee-paid group benefits, and other related services. We market our products primarily to employers interested in providing benefits to their employees. We have three major business segments: Unum US, Unum UK, and Colonial Life. Our other reporting segments are the Individual Disability — Closed Block segment and the Corporate and Other segment. See Note 12 for further discussion of our operating segments. Use of Estimates: The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein. Many factors influence the assumptions upon which reserves for policy and contract benefits are based, including historical trends in our experience and expected deviations from historical experience. Considerable judgment is required to interpret actual historical experience and to assess the future factors that are likely to influence the ultimate cost of settling existing claims. Given that insurance products contain inherent risks and uncertainties, the ultimate liability may be more or less than such estimates indicate. Fixed Maturity Securities: Fixed maturity securities include bonds and redeemable preferred stocks. Fixed maturity securities not bought and held for the purpose of selling in the near term but for which we do not have the positive intent and ability to hold to maturity are classified as available-for-sale and reported at fair value. Changes in the fair value of available-for-sale fixed maturity securities, except for amounts related to other-than-temporary impairment losses recognized in earnings, are reported as a component of other comprehensive income. These amounts are net of income tax and valuation adjustments to deferred acquisition costs and reserves for future policy and contract benefits which would have been recorded had the related unrealized gain or loss on these securities been realized. Interest income is recorded as part of net investment income when earned, using an effective yield method giving effect to amortization of premium and accretion of discount. Included within fixed maturity securities are mortgage-backed and asset-backed securities. We recognize investment income on these securities using a constant effective yield based on projected prepayments of the underlying loans and the estimated economic life of the securities. Actual prepayment experience is reviewed periodically, and effective yields are recalculated when differences arise between prepayments originally projected and the actual prepayments received and currently projected. The effective yield is recalculated on a retrospective basis, and the adjustment is reflected in net investment income. For fixed maturity securities on which collection of investment income is uncertain, we discontinue the accrual of investment income and recognize investment income when interest and dividends are received. Payment terms specified for fixed maturity securities may include a prepayment penalty for unscheduled payoff of the investment. Prepayment penalties are recognized as investment income when received. In determining when a decline in fair value below amortized cost of a fixed maturity security is other than temporary, we evaluate available information, both positive and negative, in reaching our conclusions. Although all available and applicable factors are considered in our analysis, our expectation of recovering the entire amortized cost basis of the security, whether we intend to sell the security, whether we more likely than not will be required to sell the security before recovery of its amortized cost, and whether the security is current on principal and interest payments are the most critical factors in determining whether impairments are other than temporary. The significance of the decline in value and the length of time during which there has been a significant decline are also important factors, but we generally do not record an impairment loss based solely on these two factors, since often other more relevant factors will impact our evaluation of a security. See also Note 2. 92 4356_2010AR_Fin_ALL.indd 92 4/4/11 3:05 PM Unum 2010 Annual Report Mortgage Loans: Mortgage loans are generally held for investment and are carried at amortized cost less an allowance for probable losses. Interest income is accrued on the principal amount of the loan based on the loan’s contractual interest rate. Prepayment penalties are recognized as investment income when received. We use a comprehensive rating system to evaluate the investment and credit risk of our mortgage loans and to identify specific properties for further inspection, analysis, and reevaluation. For mortgage loans on which collection of investment income is uncertain, we discontinue the accrual of investment income and recognize investment income in the period when an interest payment is received. We typically do not resume the accrual of interest on mortgage loans on nonaccrual status until there are significant improvements in the underlying financial condition of the borrower. We consider a loan to be delinquent if full payment is not received in accordance with the contractual terms of the loan. Mortgage loans are considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. We establish an allowance for probable losses on mortgage loans based on a review of individual loans and considering the underlying collateral, the value of which is periodically assessed. We do not purchase mortgage loans with existing credit impairments. Policy Loans: Policy loans are presented at unpaid balances directly related to policyholders. Interest income is accrued on the principal amount of the loan based on the loan’s contractual interest rate. Included in policy loans are $2,790.5 million and $2,675.7 million of policy loans ceded to reinsurers at December 31, 2010 and 2009, respectively. Other Long-term Investments: Other long-term investments are comprised primarily of freestanding derivatives with a net positive fair value, tax credit partnerships, and private equity partnerships. Freestanding derivatives are more fully described in the derivatives accounting policy which follows. Tax credit partnerships in which we have invested were formed for the purpose of investing in the construction and rehabilitation of low-income housing. Because the partnerships are structured such that there is no return of principal, the primary sources of investment return from our tax credit partnerships are tax credits and tax benefits derived from passive losses on the investments, both of which may exhibit variability over the life of the investment. These partnerships are accounted for using either the equity or the effective yield method, depending primarily on whether the tax credits are guaranteed through a letter of credit, a tax indemnity agreement, or another similar arrangement. Tax credits received from these partnerships are reported in our consolidated statements of income as either a reduction of state premium tax, included in other expenses, or a reduction of income tax. For those partnerships accounted for under the equity method, the amortization of the principal amount invested in these partnerships is reported as a component of net investment income. For those partnerships accounted for under the effective yield method, amortization of the principal amount invested is reported as a component of income tax or other expenses. Our investments in private equity partnerships are passive in nature. The underlying investments held by these partnerships include both equity and debt securities and are accounted for using the equity or cost method, depending on the level of ownership and the degree of influence over partnership operating and financial policies. For partnerships accounted for under the equity method, our portion of partnership earnings is reported as a component of net investment income in our consolidated statements of income. For those partnerships accounted for under the cost method, we record income received from partnership distributions as either a component of net investment income or of net realized investment gain or loss, in accordance with the source of the funds distributed from the partnership. Short-term Investments: Short-term investments are carried at cost. Short-term investments include investments maturing within one year, such as corporate commercial paper and U.S. Treasury bills, bank term deposits, and other cash accounts and cash equivalents earning interest. Cash and Bank Deposits: Cash and bank deposits include cash on hand and non-interest bearing cash and deposit accounts. Derivative Financial Instruments: Derivative financial instruments (including certain derivative instruments embedded in other contracts) are recognized as either assets or liabilities in our consolidated balance sheets and are reported at fair value. The accounting for changes in fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship, and further, on the type of hedging relationship. To qualify for hedge accounting, at the inception of the hedging transaction, we formally document the 4356_2010AR_Fin_ALL.indd 93 93 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 risk management objective and strategy for undertaking the hedging transaction, as well as the designation of the hedge as either a fair value hedge or a cash flow hedge. Included in this documentation is how the hedging instrument is expected to hedge the designated risk(s) related to specific assets or liabilities on the balance sheet or to specific forecasted transactions as well as a description of the method that will be used to retrospectively and prospectively assess the hedging instrument’s effectiveness and the method that will be used to measure ineffectiveness. A derivative designated as a hedging instrument must be assessed as being highly effective in offsetting the designated risk(s) of the hedged item. Hedge effectiveness is formally assessed at inception and periodically throughout the life of the designated hedging relationship, using qualitative and quantitative methods. Qualitative methods include comparison of critical terms of the derivative to the hedged item. Quantitative methods include regression or other statistical analysis of changes in fair value or cash flows associated with the hedge relationship. For those derivatives that are designated and qualify as hedging instruments, the derivative is designated, based upon the exposure being hedged, as one of the following: • Fair value hedge. Changes in the fair value of the derivative, including amounts measured as ineffectiveness, and changes in the fair value of the hedged item attributable to the risk being hedged are recognized in current earnings as a component of net realized investment gain or loss during the period of change in fair value. The gain or loss on the termination of a fair value hedge is recognized in current earnings as a component of net realized investment gain or loss. When interest rate swaps are used in hedge accounting relationships, periodic settlements are recorded in the same income statement line as the related settlements of the hedged items. • Cash flow hedge. To the extent it is effective, changes in the fair value of the derivative are reported in other comprehensive income and reclassified into earnings and reported on the same income statement line item as the hedged item and in the same period or periods during which the hedged item affects earnings. The ineffective portion of the hedge, if any, is recognized in current earnings as a component of net realized investment gain or loss during the period of change in fair value. The gain or loss on the termination of an effective cash flow hedge is reported in other comprehensive income and reclassified into earnings and reported on the same income statement line item as the hedged item and in the same period or periods during which the hedged item affects earnings. Gains or losses on the termination of ineffective hedges are reported in current earnings as a component of net realized investment gain or loss. In the event a hedged item is disposed of or the anticipated transaction being hedged is no longer likely to occur, we will terminate the related derivative and recognize the gain or loss on termination in current earnings as a component of net realized investment gain or loss. In the event a hedged item is disposed of subsequent to the termination of the hedging transaction, we reclassify any remaining gain or loss on the cash flow hedge out of accumulated other comprehensive income into current earnings as a component of the same income statement line item wherein we report the gain or loss on disposition of the hedged item. Our freestanding derivatives all qualify as hedges and have been designated as either cash flow hedges or fair value hedges. We do not have any speculative positions in our freestanding derivatives. For a derivative not designated as a hedging instrument, the change in fair value is recognized in earnings during the period of change. Changes in the fair values of certain embedded derivatives are reported as realized investment gains and losses during the period of change. In our consolidated balance sheets, we do not offset fair value amounts recognized for derivatives executed with the same counterparty under a master netting agreement and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from those master netting agreements. Fair Value Measurement: All of our fixed maturity securities are reported at fair value. Our derivative financial instruments, including certain derivative instruments embedded in other contracts, are reported as either assets or liabilities and measured at fair value. We hold an immaterial amount of equity securities, which are also reported at fair value. We define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value represents an exit price, not an entry price. The exit price objective applies regardless of our intent and/or ability to sell the asset or transfer the liability at the measurement date. Valuation techniques used for assets and liabilities accounted for at fair value are generally categorized into three types: the market approach, the income approach, and the cost approach. We use valuation techniques that are appropriate in the circumstances and for 94 4356_2010AR_Fin_ALL.indd 94 4/4/11 3:05 PM Unum 2010 Annual Report which sufficient data are available. In some cases, a single valuation technique will be appropriate. In other cases, multiple valuation techniques will be appropriate. If we use multiple valuation techniques to measure fair value, we evaluate and weigh the results, as appropriate, considering the reasonableness of the range indicated by those results. A fair value measurement is the point within that range that is most representative of fair value in the circumstances. The selection of the valuation method(s) to apply considers the definition of an exit price and depends on the nature of the asset or liability being valued. For assets and liabilities accounted for at fair value, we generally use valuation techniques consistent with the market approach, and to a lesser extent, the income approach. Inputs to valuation techniques refer broadly to the assumptions that market participants use in pricing assets or liabilities, including assumptions about risk, for example, the risk inherent in a particular valuation technique used to measure fair value and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. We prioritize the inputs to fair valuation techniques and use unobservable inputs to the extent that observable inputs are not available. We categorize our assets and liabilities measured at estimated fair value into a three-level hierarchy, based on the priority of the inputs. The fair value hierarchy gives the highest priority to inputs which are unadjusted and represent quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). See also Note 2. Realized Investment Gains and Losses: Realized investment gains and losses are reported as a component of revenue in the consolidated statements of income and are based upon specific identification of the investments sold. If we determine that the decline in value of an investment is other than temporary, the investment is written down to fair value, and an impairment loss is recognized in the current period, either in earnings or in both earnings and other comprehensive income, as applicable. Other-than-temporary impairment losses on fixed maturity securities which we intend to sell or more likely than not will be required to sell before recovery in value are recognized in earnings and equal the entire difference between the security’s amortized cost basis and its fair value. For securities which we do not intend to sell and it is not more likely than not that we will be required to sell before recovery in value, other-than-temporary impairment losses recognized in earnings generally represent the difference between the amortized cost of the security and the present value of our best estimate of cash flows expected to be collected, discounted using the effective interest rate implicit in the security at the date of acquisition. For fixed maturity securities for which we have recognized an other-than-temporary impairment loss through earnings, if through subsequent evaluation there is a significant increase in expected cash flows, the difference between the new amortized cost basis and the cash flows expected to be collected is accreted as net investment income. Deferred Acquisition Costs: Certain costs of acquiring new business that vary with and are primarily related to the production of new business have been deferred. Such costs include commissions, other agency compensation, certain selection and policy issue expenses, and certain field expenses. Acquisition costs that do not vary with the production of new business, such as commissions on group products which are generally level throughout the life of the policy, are excluded from deferral. Deferred acquisition costs are subject to recoverability testing at the time of policy issue and loss recognition testing in subsequent years. Deferred acquisition costs related to traditional policies are amortized over the premium paying period of the related policies in proportion to the ratio of the present value of annual expected premium income to the present value of total expected premium income. Such amortization is adjusted quarterly to reflect the actual policy persistency as compared to the anticipated experience. Deferred acquisition costs related to interest-sensitive policies are amortized over the lives of the policies in relation to the present value of estimated gross profits from surrender charges, mortality margins, investment returns, and expense margins. Adjustments are made quarterly to reflect actual experience for assumptions which deviate significantly compared to anticipated experience. Internal replacement transactions wherein the modification does not substantially change the policy are accounted for as continuations of the replaced contracts. Unamortized deferred acquisition costs from the original policy continue to be amortized over the expected life of the new policy, and the costs of replacing the policy are accounted for as policy maintenance costs and expensed as 4356_2010AR_Fin_ALL.indd 95 95 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 incurred. Internal replacement transactions, principally on group contracts, that result in a policy that is substantially changed are accounted for as an extinguishment of the original policy and the issuance of a new policy. Unamortized deferred acquisition costs on the original policy that was replaced are immediately expensed, and the costs of acquiring the new policy are capitalized and amortized in accordance with our accounting policies for deferred acquisition costs. Loss recognition is generally performed on an annual basis. Insurance contracts are grouped for each major product line within a segment when we perform the loss recognition tests. If loss recognition testing indicates that deferred acquisition costs are not recoverable, the deficiency is charged to expense. The assumptions used in loss recognition testing represent our best estimates of future experience. Goodwill: Goodwill is the excess of the amount paid to acquire a business over the fair value of the net assets acquired. We review the carrying amount of goodwill for impairment during the fourth quarter of each year, or more frequently if events or changes in circumstances indicate that the carrying amount might not be recoverable. Goodwill impairment testing compares the fair value of a reporting unit with its carrying amount, including goodwill. The fair values of the reporting units are determined using discounted cash flow models. The critical estimates necessary in determining fair value are projected earnings and the discount rate. We set our discount rate assumption based on an expected risk adjusted cost of capital. If the fair value of the reporting unit to which the goodwill relates is less than the carrying amount of the unamortized goodwill, the carrying amount is reduced with a corresponding charge to expense. Property and Equipment: Property and equipment is reported at cost less accumulated depreciation, which is calculated on the straight-line method over the estimated useful life. The accumulated depreciation for property and equipment was $641.6 million and $619.7 million as of December 31, 2010 and 2009, respectively. Value of Business Acquired: Value of business acquired represents the present value of future profits recorded in connection with the acquisition of a block of insurance policies. The asset is amortized based upon expected future premium income for traditional insurance policies and estimated future gross profits for interest-sensitive insurance policies. The value of business acquired, which is included in other assets in our consolidated balance sheets, was $37.6 million and $46.2 million at December 31, 2010 and 2009, respectively. The accumulated amortization for value of business acquired was $112.5 million and $108.2 million as of December 31, 2010 and 2009, respectively. The amortization of value of business acquired, which is included in other expenses in the consolidated statements of income, was $7.4 million, $7.8 million, and $7.8 million for the years ended December 31, 2010, 2009, and 2008, respectively. We periodically review the carrying amount of value of business acquired using the same methods used to evaluate deferred acquisition costs. Policy and Contract Benefits: Policy and contract benefits represent amounts paid and expected to be paid based on reported losses and estimates of incurred but not reported losses for traditional life and accident and health products. For interest-sensitive products, benefits are the amounts paid and expected to be paid on insured claims in excess of the policyholders’ policy fund balances. Policy and Contract Benefits Liabilities: Policy reserves represent future policy and contract benefits for claims not yet incurred. Policy reserves for traditional life and accident and health products are determined using the net level premium method. The reserves are calculated based upon assumptions as to interest, persistency, morbidity, and mortality that were appropriate at the date of issue. Interest rate assumptions are based on actual and expected net investment returns. Persistency assumptions are based on our actual historical experience adjusted for future expectations. Morbidity and mortality assumptions are based on actual experience or industry standards adjusted as appropriate to reflect our actual experience and future expectations. The assumptions vary by plan, year of issue, and policy duration and include a provision for adverse deviation. Policy reserves for group single premium annuities have been provided on a net single premium method. The reserves are calculated based on assumptions as to interest, mortality, and retirement that were appropriate at the date of issue. Mortality assumptions are based upon industry standards adjusted as appropriate to reflect our actual experience and future expectations. The assumptions vary by year of issue. 96 4356_2010AR_Fin_ALL.indd 96 4/4/11 3:05 PM Unum 2010 Annual Report Policy reserves for interest-sensitive products are principally policyholder account values. We perform loss recognition tests on our policy reserves annually, or more frequently if appropriate, using best estimate assumptions as of the date of the test, without a provision for adverse deviation. We group the policy reserves for each major product line within a segment when we perform the loss recognition tests. If the policy reserves determined using these best estimate assumptions are higher than our existing policy reserves net of any deferred acquisition cost balance, the existing policy reserves are increased or deferred acquisition costs are reduced to immediately recognize the deficiency. Claim reserves represent future policy and contract benefits for claims that have been incurred or are estimated to have been incurred but not yet reported to us. Our claim reserves relate primarily to disability policies and are calculated based on assumptions as to interest and claim resolution rates that are currently appropriate. Claim resolution rate assumptions are based on our actual experience. The interest rate assumptions used for discounting claim reserves are based on projected portfolio yield rates, after consideration for defaults and investment expenses, for the assets supporting the liabilities for the various product lines. Unlike policy reserves, claim reserves are subject to revision as current claim experience and projections of future experience change. Policyholders’ Funds: Policyholders’ funds represent customer deposits plus interest credited at contract rates. We control interest rate risk by investing in quality assets which have an aggregate duration that closely matches the expected duration of the liabilities. Income Tax: Deferred taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial statement purposes and the amounts used for income tax purposes. Deferred taxes have been measured using enacted statutory income tax rates and laws that are currently in effect. We record deferred tax assets for tax positions taken in the U.S. and other tax jurisdictions based on our assessment of whether a position is more likely than not to be sustained upon examination based solely on its technical merits. A valuation allowance is established for deferred tax assets when it is more likely than not that an amount will not be realized. Short-term and Long-term Debt: Short-term and long-term debt are carried at the unpaid principal balance, net of unamortized discount or premium. Short-term debt is debt due within the next twelve months, including that portion of debt otherwise classified as long-term. Original issue discount or premium as well as debt issue costs are recognized as a component of interest expense over the period the debt is expected to be outstanding. The carrying amount of long-term debt that is part of a fair value hedge program includes an adjustment to reflect the effect of the change in fair value attributable to the risk being hedged. Net interest settlements for fair value hedges on our long-term debt are recognized as a component of interest expense. Treasury Stock: Treasury stock is reflected as a reduction of stockholders’ equity at cost. Revenue Recognition: Traditional life and accident and health products are long-duration contracts, and premium income is recognized as revenue when due from policyholders. If the contracts are experience rated, the estimated ultimate premium is recognized as revenue over the period of the contract. The estimated ultimate premium, which is revised to reflect current experience, is based on estimated claim costs, expenses, and profit margins. For interest-sensitive products, the amounts collected from policyholders are considered deposits, and only the deductions during the period for cost of insurance, policy administration, and surrenders are included in revenue. Policyholders’ funds represent funds deposited by contract holders and are not included in revenue. Reinsurance: We routinely enter into reinsurance agreements with other insurance companies to spread risk and thereby limit losses from large exposures. For each of our reinsurance agreements, we determine if the agreement provides indemnification against loss or liability relating to insurance risk in accordance with applicable accounting standards. If we determine that a reinsurance agreement does not expose the reinsurer to a reasonable possibility of a significant loss from insurance risk, we record the agreement using the deposit method of accounting. 4356_2010AR_Fin_ALL.indd 97 97 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 Reinsurance activity is accounted for on a basis consistent with the terms of the reinsurance contracts and the accounting used for the original policies issued. Premium income and benefits and change in reserves for future benefits are presented in our consolidated statements of income net of reinsurance ceded. Ceded policy and contract benefits, ceded future policy and contract benefits, ceded unearned premiums, and ceded policy loans are reported on a gross basis in our consolidated balance sheets. Our reinsurance recoverable includes the balances due from reinsurers under the terms of the reinsurance agreements for these ceded balances as well as settlement amounts currently due. Where applicable, gains or losses on reinsurance transactions are deferred and amortized into earnings based upon expected future premium income for traditional insurance policies and estimated future gross profits for interest-sensitive insurance policies. The deferred gain on reinsurance included in other liabilities in our consolidated balance sheets at December 31, 2010 and 2009 was $100.2 million and $123.1 million, respectively. Under ceded reinsurance agreements wherein we are not relieved of our legal liability to our policyholders, if the assuming reinsurer is unable to meet its obligations, we remain contingently liable. We evaluate the financial condition of reinsurers and monitor concentration of credit risk to minimize this exposure. We may also require assets in trust, letters of credit, or other acceptable collateral to support our reinsurance recoverable balances. In the event that reinsurers do not meet their obligations to us under the terms of the reinsurance agreements, certain amounts reported in our reinsurance recoverable could become uncollectible, in which case the reinsurance recoverable balances are stated net of allowances for uncollectible reinsurance. Premium Tax Expense: Premium tax expense is included in other operating expenses in the consolidated statements of income. For the years ended December 31, 2010, 2009, and 2008, premium tax expense was $129.4 million, $130.2 million, and $133.2 million, respectively. Stock-Based Compensation: The cost of stock-based compensation is generally measured based on the grant-date fair value of the award. We use the Black-Scholes options valuation model for estimating the fair value of stock options and the Monte-Carlo model for estimating the fair value of our performance restricted stock units. Nonvested stock awards are valued based on the market value of common stock at the grant date, and cash-settled awards are measured each reporting period based on the current stock price. Stock-based awards that do not require future service are expensed immediately, and stock-based awards that require future service are amortized over the relevant service period, with an offsetting increase to additional paid-in capital in stockholders’ equity. Earnings Per Share: We compute basic earnings per share by dividing net income by the weighted average number of common shares outstanding for the period. Earnings per share assuming dilution is computed by dividing net income by the weighted average number of shares outstanding for the period plus the shares representing the dilutive effect of stock-based awards. We use the treasury stock method to account for the effect of outstanding stock options, nonvested stock awards, and performance restricted stock units on the computation of earnings per share assuming dilution. Translation of Foreign Currency: Revenues and expenses of our foreign operations are translated at average exchange rates. Assets and liabilities are translated at the rate of exchange on the balance sheet dates. The translation gain or loss is generally reported in accumulated other comprehensive income, net of deferred tax. Accounting for Participating Individual Life Insurance: Participating policies issued by one of our subsidiaries prior to its 1986 conversion from a mutual to a stock life insurance company will remain participating as long as the policies remain in-force. A Participation Fund Account (PFA) was established for the benefit of all such individual participating life and annuity policies and contracts. The assets of the PFA provide for the benefit, dividend, and certain expense obligations of the participating individual life insurance policies and annuity contracts. The assets of the PFA were $364.4 million and $359.8 million at December 31, 2010 and 2009, respectively. Accounting Updates Adopted in 2010: Accounting Standards Codification (ASC 310) “Receivables.” In July 2010, the Financial Accounting Standards Board (FASB) issued an update to require additional disclosures regarding the credit quality of financing receivables, including the entity’s credit risk exposure, its assessment of risk in estimating its allowance for credit losses, changes in the allowance for credit losses, and the reason for those changes. The disclosure requirements of this update have staggered effective dates. We adopted the disclosures around the entity’s credit risk 98 4356_2010AR_Fin_ALL.indd 98 4/4/11 3:05 PM Unum 2010 Annual Report exposure and its assessment of risk in estimating its allowance for credit losses effective December 31, 2010. The adoption of this update expanded our disclosures but had no effect on our financial position or results of operation. ASC 810 “Consolidation.” In June 2009, the FASB issued an update to require a qualitative rather than a quantitative analysis to determine the primary beneficiary of a variable interest entity and require enhanced disclosures about an enterprise’s involvement with a variable interest entity. We adopted this update effective January 1, 2010. The adoption of this update had no effect on our financial position or results of operations. ASC 820 “Fair Value Measurements and Disclosures.” In January 2010, the FASB issued an update to require a number of additional disclosures regarding fair value measurements. Specifically, the update requires a reporting entity to disclose the amounts of significant transfers between Level 1 and Level 2 of the three tier fair value hierarchy and the reasons for these transfers, as well as the reasons for any transfers in or out of Level 3, effective for annual and interim periods beginning after December 15, 2009. The update also requires information in the reconciliation of recurring Level 3 measurements about purchases, sales, issuances, and settlements on a gross basis, effective for annual and interim periods beginning after December 15, 2010. We adopted this update in its entirety, including early adoption of the additional Level 3 information, effective January 1, 2010. The adoption of this update expanded our disclosures but had no effect on our financial position or results of operations. ASC 860 “Transfers and Servicing.” In June 2009, the FASB issued an update to eliminate the exceptions for qualifying special-purpose entities from the consolidation guidance and eliminate the exception that permitted sale accounting for certain mortgage securitizations when a transferor has not surrendered control over the transferred financial assets. In addition, this update clarifies certain requirements for financial assets that are eligible for sale accounting and requires enhanced disclosures about the risks that a transferor continues to be exposed to because of its continuing involvement in transferred financial assets. We adopted this update effective January 1, 2010. The adoption of this update had no effect on our financial position or results of operations. Accounting Updates Adopted in 2009: ASC 105 “Generally Accepted Accounting Principles.” In June 2009, the FASB established the FASB Accounting Standards Codification (Codification) as the source of authoritative accounting principles to be applied by nongovernmental entities in the preparation of financial statements in conformity with GAAP. Securities and Exchange Commission (SEC) rules and interpretive releases, which may not be included in their entirety within the Codification, will remain as authoritative GAAP for SEC registrants. We adopted Codification effective July 1, 2009. The adoption of Codification had no effect on our financial position or results of operations. ASC 320 “Investments — Debt and Equity Securities.” In April 2009, the FASB issued a new accounting standard, now included in ASC 320, which amends the other-than-temporary impairment guidance for debt securities and expands and increases the frequency of previously existing disclosures for other-than-temporary impairments. The measure of impairment remains fair value. Under the standard, an other-than-temporary impairment must be recognized in earnings for a debt security in an unrealized loss position when an entity either (a) has the intent to sell the debt security or (b) more likely than not will be required to sell the debt security before its anticipated recovery. The amount of impairment recognized is equal to the difference between amortized cost and fair value. For all debt securities in unrealized loss positions that do not meet either of these two criteria, the standard requires that an entity analyze its ability to recover the amortized cost by comparing the present value of cash flows with the amortized cost of the security. If the present value of our best estimate of cash flows expected to be collected is less than the amortized cost of the security, an other-than-temporary impairment is recorded. The impairment loss is separated into two components, the portion of the impairment related to credit and the portion related to factors other than credit. The credit-related portion of an other-than-temporary impairment, which is the difference between the amortized cost of the security and the present value of cash flows expected to be collected, is recognized in earnings. Other-than-temporary impairments related to factors other than credit are charged to earnings if it is unlikely that the fair value of the security will recover prior to its disposal. Otherwise, non-credit-related other-than-temporary impairments are charged to other comprehensive income, net of tax. We adopted this standard effective April 1, 2009. The cumulative effect of applying the provisions of this standard increased the April 1, 2009 opening balance of retained earnings $14.3 million, net of tax of $7.7 million, with a corresponding adjustment to accumulated other comprehensive income (loss). 4356_2010AR_Fin_ALL.indd 99 99 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 ASC 715 “Compensation — Retirement Benefits.” In December 2008, the FASB issued a new accounting standard, now included in ASC 715, to provide guidance on an employer’s disclosures about plan assets of a defined benefit pension or other postretirement plan. We adopted this standard effective December 31, 2009. This standard expanded our disclosures but had no effect on our financial position or results of operations. ASC 815 “Derivatives and Hedging.” In March 2008, the FASB issued a new accounting standard, now included in ASC 815, to provide additional guidance intended to improve financial reporting about derivative instruments and hedging activities. This standard requires enhanced disclosures to enable investors to better understand their effects on an entity’s financial position, financial performance, and cash flows. We adopted this standard effective January 1, 2009. This standard expanded our disclosures but had no effect on our financial position or results of operations. ASC 820 “Fair Value Measurements and Disclosures.” In April 2009, the FASB issued a new accounting standard, now included in ASC 820, to provide additional guidance for estimating fair value but reemphasized that the objective of fair value measurement remained an exit price. This standard provides guidance for determining whether there has been a significant decrease in the volume and level of activity in the market and provides factors for companies to consider in identifying transactions that are not orderly. The standard also discusses the necessity of adjustments to transaction or quoted prices to estimate fair value when it is determined that there has been a significant decrease in the volume and level of activity or that the transaction is not orderly. We adopted this standard effective April 1, 2009. This standard expanded our disclosures but did not have a material effect on our financial position or results of operations. In August 2009, the FASB issued an update to provide clarification concerning fair value measurements and disclosures for liabilities and, in particular, for circumstances in which a quoted price in an active market for an identical liability is not available. We adopted this update effective December 31, 2009. The adoption of this update had no effect on our financial position or results of operations. In September 2009, the FASB issued an update to permit a reporting entity to measure the fair value of an investment on the basis of net asset value per share if the net asset value is calculated in a manner consistent with the measurement principles of U.S. GAAP for investment companies. This update also requires disclosures by major category of investments about the attributes of investments, such as the nature of any restrictions on the investor’s ability to redeem its investments, any unfunded commitments, and the investment strategies of the investees. We adopted this update effective December 31, 2009. The adoption of this update had no effect on our financial position or results of operations. ASC 825 “Financial Instruments.” In April 2009, the FASB issued a new accounting standard, now included in ASC 825, which requires companies to disclose the fair value of certain financial instruments in interim financial statements. This standard also requires companies to disclose the method or methods and significant assumptions used to estimate the fair value of financial instruments and to discuss changes, if any, in those methods or assumptions during the period. We adopted this standard effective April 1, 2009. This standard expanded our disclosures but had no effect on our financial position or results of operations. 100 4356_2010AR_Fin_ALL.indd 100 4/4/11 3:05 PM Unum 2010 Annual Report ASC 855 “Subsequent Events.” In May 2009, the FASB issued a new accounting standard, now included in ASC 855, to provide subsequent events guidance. This topic was previously addressed only in the auditing literature, and is largely similar to the auditing guidance with limited exceptions which are not intended to result in significant changes in practice. We adopted this standard effective June 30, 2009. The FASB issued an update in February 2010 to remove the requirement, for certain entities, to disclose the date through which subsequent events have been evaluated. This standard and update had no effect on our financial position or results of operations. Accounting Updates Adopted in 2008: ASC 325 “Investments — Other.” In January 2009, the FASB issued a new accounting standard, now included in ASC 325, to amend the impairment guidance on purchased beneficial interests and beneficial interests that continue to be held by a transferor in securitized financial assets to achieve more consistent determination of whether an other-than-temporary impairment has occurred. This standard retains and emphasizes the objective of an other-than-temporary impairment assessment and the related disclosure requirements for certain investments in debt and equity securities. We adopted this standard effective December 31, 2008. The adoption of this standard did not have a material effect on our financial position or results of operations. ASC 820 “Fair Value Measurements and Disclosures.” In September 2006, the FASB issued a new accounting standard, now included in ASC 820, to define fair value, establish a framework for measuring fair value, and expand disclosures about fair value measurements. We adopted this standard effective January 1, 2008. The adoption of this standard did not have a material effect on our financial position or results of operations. Accounting Updates Outstanding: ASC 310 “Receivables.” As previously noted, in July 2010, the FASB issued an update to require additional disclosures regarding the credit quality of financing receivables. Disclosures around changes in the allowance for credit losses and the reason for those changes are effective for interim and annual reporting periods beginning on or after June 15, 2011. The adoption of this update will expand our disclosures for financing receivables, primarily our investments in mortgage loans, but will have no effect on our financial position or results of operations. ASC 944 “Financial Services — Insurance.” In October 2010, the FASB issued an update which is intended to address diversity in practice regarding the interpretation of which costs relating to the acquisition of new or renewal insurance contracts qualify as deferred acquisition costs. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2011, and permit retrospective application. The guidance in this update will result in a decrease in the opening balance of our retained earnings if we choose retrospective application on adoption and will result in a decrease in the level of costs we defer subsequent to adoption. Given that application guidance is still evolving, we have not yet finalized the expected impact on our financial position or results of operations. 4356_2010AR_Fin_ALL.indd 101 101 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 Note 2. Fair Values of Financial Instruments Presented as follows are the carrying amounts and fair values of financial instruments. The carrying values of financial instruments such as short-term investments, cash and bank deposits, accounts and premiums receivable, and accrued investment income approximate fair value due to the short-term nature of the instruments. As such, these financial instruments are not included in the following chart.

Fair Value Measurements for Financial Instruments Not Carried at Fair Value Mortgage Loans: Fair values are estimated using discounted cash flow analyses and interest rates currently being offered for similar loans to borrowers with similar credit ratings and maturities. Loans with similar characteristics are aggregated for purposes of the calculations. Policy Loans: Fair values for policy loans, net of reinsurance ceded, are estimated using discounted cash flow analyses and interest rates currently being offered to policyholders with similar policies. The carrying amounts of ceded policy loans of $2,790.5 million and $2,675.7 million as of December 31, 2010 and 2009, respectively, are reported on a gross basis in our consolidated balance sheets and approximate fair value. Miscellaneous Long-term Investments: Carrying amounts approximate fair value. 102 4356_2010AR_Fin_ALL.indd 102 4/4/11 3:05 PM Unum 2010 Annual Report Policyholders’ Funds: Policyholders’ funds are comprised primarily of deferred annuity products and supplementary contracts without life contingencies. The carrying amounts approximate fair value. Fair values for insurance contracts other than investment contracts are not required to be disclosed. However, the fair values of liabilities under all insurance contracts are taken into consideration in our overall management of interest rate risk, which minimizes exposure to changing interest rates through the matching of investment maturities with amounts due under insurance contracts. Short-term and Long-term Debt: Fair values are obtained from independent pricing services or discounted cash flow analyses based on current incremental borrowing rates for similar types of borrowing arrangements. Unfunded Commitments to Investment Partnerships: Unfunded equity commitments represent legally binding amounts that we have committed to certain investment partnerships, subject to the partnerships meeting specified conditions. When these conditions are met, we are obligated to invest these amounts in the partnerships. Carrying amounts approximate fair value. Fair Value Measurements for Financial Instruments Carried at Fair Value We report fixed maturity securities, derivative financial instruments, and equity securities at fair value in our consolidated balance sheets. The degree of judgment utilized in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Financial instruments with readily available active quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and less judgment utilized in measuring fair value. An active market for a financial instrument is a market in which transactions for an asset or a similar asset occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value and should be used to measure fair value whenever available. Conversely, financial instruments rarely traded or not quoted have less observability and are measured at fair value using valuation techniques that require more judgment. Pricing observability is generally impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction, and overall market conditions. Valuation techniques used for assets and liabilities accounted for at fair value are generally categorized into three types. The market approach uses prices and other relevant information from market transactions involving identical or comparable assets or liabilities. The income approach converts future amounts, such as cash flows or earnings, to a single present amount, or a discounted amount. The cost approach is based upon the amount that currently would be required to replace the service capacity of an asset, or the current replacement cost. We use valuation techniques that are appropriate in the circumstances and for which sufficient data are available that can be obtained without undue cost and effort. In some cases, a single valuation technique will be appropriate (for example, when valuing an asset or liability using quoted prices in an active market for identical assets or liabilities). In other cases, multiple valuation techniques will be appropriate. If we use multiple valuation techniques to measure fair value, we evaluate and weigh the results, as appropriate, considering the reasonableness of the range indicated by those results. A fair value measurement is the point within that range that is most representative of fair value in the circumstances. The selection of the valuation method(s) to apply considers the definition of an exit price and depends on the nature of the asset or liability being valued. For assets and liabilities accounted for at fair value, we generally use valuation techniques consistent with the market approach, and to a lesser extent, the income approach. We believe the market approach valuation technique provides more observable data than the income approach, considering the type of investments we hold. Our fair value measurements could differ significantly based on the valuation technique and available inputs. When markets are less active, brokers may rely more on models with inputs based on the information available only to the broker. In weighing a broker quote as an input to fair value, we place less reliance on quotes that do not reflect the result of market transactions. We also consider the nature of the quote, particularly whether the quote is a binding offer. If prices in an inactive market do not reflect current prices for the same or similar assets, adjustments may be necessary to arrive at fair value. 4356_2010AR_Fin_ALL.indd 103 103 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 When relevant market data is unavailable, which may be the case during periods of market uncertainty, the income approach can, in suitable circumstances, provide a more appropriate fair value. During 2010, we have applied valuation techniques on a consistent basis to similar assets and liabilities and consistent with those techniques used at year end 2009. We use observable and unobservable inputs in measuring the fair value of our financial instruments. Inputs that may be used include the following: • Broker market maker prices and price levels • Trade Reporting and Compliance Engine (TRACE) pricing • Prices obtained from external pricing services • Benchmark yields (Treasury and interest rate swap curves) • Transactional data for new issuance and secondary trades • Security cash flows and structures • Recent issuance/supply • Sector and issuer level spreads • Security credit ratings/maturity/capital structure/optionality • Corporate actions • Underlying collateral • Prepayment speeds/loan performance/delinquencies/weighted average life/seasoning • Public covenants • Comparative bond analysis • Derivative spreads • Relevant reports issued by analysts and rating agencies • Audited financial statements We review all prices obtained to ensure they are consistent with a variety of observable market inputs and to verify the validity of a security’s price. The overall valuation process for determining fair values may include adjustments to valuations obtained from our pricing sources when they do not represent a valid exit price. These adjustments may be made when, in our judgment and considering our knowledge of the financial conditions and industry in which the issuer operates, certain features of the financial instrument require that an adjustment be made to the value originally obtained from our pricing sources. These features may include the complexity of the financial instrument, the market in which the financial instrument is traded, counterparty credit risk, credit structure, concentration, or liquidity. Additionally, an adjustment to the price derived from a model typically reflects our judgment of the inputs that other participants in the market for the financial instrument being measured at fair value would consider in pricing that same financial instrument. The parameters and inputs used to validate a price on a security may be adjusted for assumptions about risk and current market conditions on a quarter to quarter basis, as certain features may be more significant drivers of valuation at the time of pricing. Changes to inputs in valuations are not changes to valuation methodologies; rather, the inputs are modified to reflect direct or indirect impacts on asset classes from changes in market conditions. Fair values for derivatives other than embedded derivatives in modified coinsurance arrangements are based on market quotes or pricing models and represent the net amount of cash we would have paid or received if the contracts had been settled or closed as of the last day of the period. We analyze credit default swap spreads relative to the average credit spread embedded within the London Interbank Offered Rate (LIBOR) setting syndicate in determining the effect of credit risk on our derivatives’ fair values. If counterparty credit risk for a derivative asset is determined to be material and is not adequately reflected in the LIBOR-based fair value obtained from our pricing sources, we adjust the valuations obtained from our pricing sources. In regard to our own credit risk component, we adjust the valuation of derivative liabilities wherein the counterparty is exposed to our credit risk when the LIBOR-based valuation of our derivatives obtained from pricing sources does not effectively include an adequate credit component for our own credit risk. 104 4356_2010AR_Fin_ALL.indd 104 4/4/11 3:05 PM Unum 2010 Annual Report Fair values for our embedded derivative in a modified coinsurance arrangement are estimated using internal pricing models and represent the hypothetical value of the duration mismatch of assets and liabilities, interest rate risk, and third party credit risk embedded in the modified coinsurance arrangement. Certain of our investments do not have readily determinable market prices and/or observable inputs or may at times be affected by the lack of market liquidity. For these securities, we use internally prepared valuations combining matrix pricing with vendor purchased software programs, including valuations based on estimates of future profitability, to estimate the fair value. Additionally, we may obtain prices from independent third-party brokers to aid in establishing valuations for certain of these securities. Key assumptions used by us to determine fair value for these securities include risk free interest rates, risk premiums, performance of underlying collateral (if any), and other factors involving significant assumptions which may or may not reflect those of an active market. At December 31, 2010, approximately 13.5 percent of our fixed maturity securities were valued using active trades from TRACE pricing or broker market maker prices for which there was current market activity in that specific security (comparable to receiving one binding quote). The prices obtained were not adjusted, and the assets were classified as Level 1, the highest category of the three-level fair value hierarchy classification wherein inputs are unadjusted and represent quoted prices in active markets for identical assets or liabilities. The remaining 86.5 percent of our fixed maturity securities were valued based on non-binding quotes or other observable or unobservable inputs, as discussed below. • Approximately 69.7 percent of our fixed maturity securities were valued based on prices from pricing services that generally use observable inputs such as prices for securities or comparable securities in active markets in their valuation techniques. These assets were classified as Level 2. Level 2 assets or liabilities are those valued using inputs (other than prices included in Level 1) that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. • Approximately 5.3 percent of our fixed maturity securities were valued based on one or more non-binding broker price levels, if validated by observable market data, or on TRACE prices for identical or similar assets absent current market activity. When only one price is available, it is used if observable inputs and analysis confirms that it is appropriate. These assets, for which we were able to validate the price using other observable market data, were classified as Level 2. • Approximately 11.5 percent of our fixed maturity securities were valued based on prices of comparable securities, matrix pricing, market models, and/or internal models or were valued based on non-binding quotes with no other observable market data. These assets were classified as either Level 2 or Level 3, with the categorization dependent on whether there was other observable market data. Level 3 is the lowest category of the fair value hierarchy and reflects the judgment of management regarding what market participants would use in pricing assets or liabilities at the measurement date. Financial assets and liabilities categorized as Level 3 are generally those that are valued using unobservable inputs to extrapolate an estimated fair value. We consider transactions in inactive or disorderly markets to be less representative of fair value. We use all available observable inputs when measuring fair value, but when significant other unobservable inputs and adjustments are necessary, we classify these assets or liabilities as Level 3. 4356_2010AR_Fin_ALL.indd 105 105 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 The categorization of fair value measurements by input level is as follows: December 31, 2010 Quoted Prices in Active Markets for Identical Assets or Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (in millions of dollars) Assets Fixed Maturity Securities United States Government and Government Agencies and Authorities $ 102.8 $ 998.9 $ — $ 1,101.7 States, Municipalities, and Political Subdivisions Foreign Governments Public Utilities Mortgage/Asset-Backed Securities All Other Corporate Bonds Redeemable Preferred Stocks 301.9 0.7 840.1 — 943.3 1,408.6 8,670.5 3,384.8 4,170.7 18,154.3 — 33.3 — — 173.6 0.7 829.7 21.7 1,245.2 1,409.3 9,684.2 3,385.5 23,154.7 55.0 Total Fixed Maturity Securities 5,416.2 33,593.7 1,025.7 40,035.6 Other Long-term Investments Derivatives Interest Rate Swaps Foreign Exchange Contracts Total Derivatives Equity Securities Liabilities Other Liabilities Derivatives Interest Rate Swaps Foreign Exchange Contracts Embedded Derivative in Modified Coinsurance Arrangement Total Derivatives — — — — 98.4 0.7 99.1 8.9 — — — 1.5 98.4 0.7 99.1 10.4 $ — $ 39.1 $ — $ 39.1 — — — 160.5 — 199.6 — 96.3 96.3 160.5 96.3 295.9 106 4356_2010AR_Fin_ALL.indd 106 4/4/11 3:05 PM Unum 2010 Annual Report December 31, 2009 Quoted Prices in Active Markets for Identical Assets or Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (in millions of dollars) Assets Fixed Maturity Securities United States Government and Government Agencies and Authorities $ — $ 1,473.2 $ — $ 1,473.2 States, Municipalities, and Political Subdivisions Foreign Governments Public Utilities Mortgage/Asset-Backed Securities All Other Corporate Bonds Redeemable Preferred Stocks Total Fixed Maturity Securities Other Long-term Investments Derivatives Interest Rate Swaps Equity Securities Liabilities Other Liabilities Derivatives 75.6 — 940.4 — 3,370.6 5.5 4,392.1 547.3 1,491.5 7,577.0 3,718.4 17,830.5 15.0 32,652.9 — — 81.1 — — — 264.3 4.7 580.0 20.4 869.4 — 1.5 622.9 1,491.5 8,781.7 3,723.1 21,781.1 40.9 37,914.4 81.1 1.5 Interest Rate Swaps Foreign Exchange Contracts Embedded Derivative in Modified Coinsurance Arrangement Total Derivatives $ — $ 17.0 $ — $ 17.0 — — — 127.6 — 144.6 — 127.6 117.4 117.4 117.4 262.0 Transfers of assets between Level 1 and Level 2 are as follows: (in millions of dollars) Fixed Maturity Securities Year Ended December 31, 2010 Transfers into Level 1 from Level 2 Transfers into Level 2 from Level 1 United States Government and Government Agencies and Authorities $ 95.9 $ — States, Municipalities, and Political Subdivisions Foreign Governments Public Utilities All Other Corporate Bonds Redeemable Preferred Stocks Total Fixed Maturity Securities 36.2 0.7 483.2 1,940.1 — $2,556.1 33.7 — 673.6 1,676.6 5.5 $2,389.4 4356_2010AR_Fin_ALL.indd 107 107 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 Transfers between Level 1 and Level 2 occurred due to the change in availability of either a TRACE or broker market maker price.

The transfers between levels resulted primarily from a change in observability of three inputs used to determine fair values of the securities transferred: (1) transactional data for new issuance and secondary trades, (2) broker/dealer quotes and pricing, primarily related to changes in the level of activity in the market and whether the market was considered orderly, and (3) comparable bond metrics from which to perform an analysis. For fair value measurements of financial instruments that were transferred either into or out of Level 3, we reflect the transfers using the fair value at the beginning of the period. Gains for the years ended December 31, 2010 and 2009 which are included in earnings and are attributable to the change in unrealized gains or losses relating to assets or liabilities valued using significant unobservable inputs and still held at each year end were $21.1 million and $243.1 million, respectively. These amounts relate entirely to the changes in fair value of an embedded derivative in a modified coinsurance arrangement which are reported as realized investment gains and losses. Note 3.

The gross unrealized loss on investment-grade fixed maturity securities was 77.9 percent of the total gross unrealized loss on fixed maturity securities. Unrealized losses on investment-grade fixed maturity securities principally relate to changes in interest rates or changes in market or sector credit spreads which occurred subsequent to the acquisition of the securities. At December 31, 2010, the fair value of below-investment-grade fixed maturity securities was $2,755.0 million, with a gross unrealized gain of $138.6 million and a gross unrealized loss of $52.5 million. The gross unrealized loss on below-investment-grade fixed maturity securities was 22.1 percent of the total gross unrealized loss on fixed maturity securities. Generally, below-investment-grade fixed maturity securities are more likely to develop credit concerns than investment-grade securities. At December 31, 2010, the unrealized losses in our below-investment-grade fixed maturity securities were generally due to credit spreads in certain industries or sectors and, to a lesser extent, credit concerns related to specific securities. For each specific security in an unrealized loss position, we believe that there are positive factors which mitigate credit concerns and that the securities for which we have not recorded an other-than-temporary impairment will recover in value. As of December 31, 2010, we held 220 individual investment-grade fixed maturity securities and 42 individual below-investment- grade fixed maturity securities that were in an unrealized loss position, of which 60 investment-grade fixed maturity securities and 29 below-investment-grade fixed maturity securities had been in an unrealized loss position continuously for over one year. 4356_2010AR_Fin_ALL.indd 111 111 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 In determining when a decline in fair value below amortized cost of a fixed maturity security is other than temporary, we evaluate the following factors: • Whether we expect to recover the entire amortized cost basis of the security. • Whether we intend to sell the security or will be required to sell the security before the recovery of its amortized cost basis. • Whether the security is current as to principal and interest payments. • The significance of the decline in value. • The time period during which there has been a significant decline in value. • Current and future business prospects and trends of earnings. • The valuation of the security’s underlying collateral. • Relevant industry conditions and trends relative to their historical cycles. • Market conditions. • Rating agency and governmental actions. • Bid and offering prices and the level of trading activity. • Adverse changes in estimated cash flows for securitized investments. • Changes in fair value subsequent to the balance sheet date. • Any other key measures for the related security. We evaluate available information, including the factors noted above, both positive and negative, in reaching our conclusions. In particular, we also consider the strength of the issuer’s balance sheet, its debt obligations and near term funding requirements, cash flow and liquidity, the profitability of its core businesses, the availability of marketable assets which could be sold to increase liquidity, its industry fundamentals and regulatory environment, and its access to capital markets. Although all available and applicable factors are considered in our analysis, our expectation of recovering the entire amortized cost basis of the security, whether we intend to sell the security, whether it is more likely than not we will be required to sell the security before recovery of its amortized cost, and whether the security is current on principal and interest payments are the most critical factors in determining whether impairments are other than temporary. The significance of the decline in value and the length of time during which there has been a significant decline are also important factors, but we generally do not record an impairment loss based solely on these two factors, since often other more relevant factors will impact our evaluation of a security. While determining other-than-temporary impairments is a judgmental area, we utilize a formal, well-defined, and disciplined process to monitor and evaluate our fixed income investment portfolio, supported by issuer specific research and documentation as of the end of each period. The process results in a thorough evaluation of problem investments and the recording of losses on a timely basis for investments determined to have an other-than-temporary impairment. If we determine that the decline in value of an investment is other than temporary, the investment is written down to fair value, and an impairment loss is recognized in the current period, either in earnings or in both earnings and other comprehensive income, as applicable. For those fixed maturity securities with an unrealized loss for which we have not recognized an other-than-temporary impairment, we believe we will recover the entire amortized cost, we do not intend to sell the security, and we do not believe it is more likely than not we will be required to sell the security before recovery of its amortized cost. There have been no defaults in the repayment obligations of any securities for which we have not recorded an other-than-temporary impairment. Other-than-temporary impairment losses on fixed maturity securities which we intend to sell or more likely than not will be required to sell before recovery in value are recognized in earnings and equal the entire difference between the security’s amortized cost basis and its fair value. For securities which we do not intend to sell and it is not more likely than not that we will be required to sell before recovery in value, other-than-temporary impairment losses recognized in earnings generally represent the difference between the amortized cost of the security and the present value of our best estimate of cash flows expected to be collected, discounted using the effective interest rate implicit in the security at the date of acquisition. The determination of cash flows is inherently subjective, and methodologies may vary depending on the circumstances specific to the security. The timing and amount of our cash flow estimates are developed using historical and forecast financial information from the issuer, including its current and projected liquidity position. We also consider industry analyst 112 4356_2010AR_Fin_ALL.indd 112 4/4/11 3:05 PM Unum 2010 Annual Report reports and forecasts, sector credit ratings, future business prospects and earnings trends, issuer refinancing capabilities, actual and/or potential asset sales by the issuer, and other data relevant to the collectibility of the contractual cash flows of the security. We take into account the probability of default, expected recoveries, third party guarantees, quality of collateral, and where our debt security ranks in terms of subordination. We may use the estimated fair value of collateral as a proxy for the present value of cash flows if we believe the security is dependent on the liquidation of collateral for recovery of our investment. For fixed maturity securities for which we have recognized an other-than-temporary impairment loss through earnings, if through subsequent evaluation there is a significant increase in expected cash flows, the difference between the new amortized cost basis and the cash flows expected to be collected is accreted as net investment income. The following table presents the before-tax credit-related portion of other-than-temporary impairments on fixed maturity securities still held as of the dates shown for which a portion of the other-than-temporary impairment was recognized in other comprehensive income.

These commitments are not legally binding and may or may not be funded. Variable Interest Entities We invest in variable interests issued by variable interest entities. These investments include tax credit partnerships, private equity partnerships, and special purpose entities. For those variable interests that are not consolidated in our financial statements, we are not the primary beneficiary because we have neither the power to direct the activities that are most significant to economic performance nor the responsibility to absorb a majority of the expected losses. The determination of whether we are the primary beneficiary is performed at the time of our initial investment and at the date of each subsequent reporting period. As of December 31, 2010, the carrying amount of our variable interest entity investments that are not consolidated under the provisions of GAAP was $370.0 million, comprised of $277.2 million of tax credit partnerships and $92.8 million of private equity partnerships. These variable interest entity investments are reported as other long-term investments in our consolidated balance sheets. Additionally, we recognize a liability for all legally binding unfunded commitments to these partnerships, with a corresponding recognition of an invested asset. Our liability for legally binding unfunded commitments to the tax credit partnerships was $169.9 million at December 31, 2010. Contractually, we are a limited partner in these investments, and our maximum exposure to loss is limited to the carrying value of our investment. We also had commitments of $73.0 million to fund certain of the private equity partnerships at December 31, 2010. These commitments are not legally binding and may or may not be funded during the life of the partnerships. We are the sole beneficiary of a special purpose entity which is consolidated under the provisions of GAAP. This entity is a securitized asset trust containing a highly rated bond for principal protection, nonredeemable preferred stock, and several partnership equity investments. We contributed the bond and partnership investments into the trust at the time it was established. The trust supports our investment objectives and allows us to maintain our investment in the partnerships while at the same time protecting the principal of the investment. There are no restrictions on the assets held in this trust, and the trust is free to dispose of the assets at any time. Because the 4356_2010AR_Fin_ALL.indd 113 113 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 assets in the trust are not liquid investments, we periodically provide funding to the underlying partnerships in the trust upon satisfaction of contractual notice from the partnerships. The fair values of the bond, nonredeemable preferred stock, and partnerships were $102.2 million, $0.1 million, and $9.3 million, respectively, as of December 31, 2010. The bonds are reported as fixed maturity securities, and the nonredeemable preferred stock and partnerships are reported as other long-term investments in our consolidated balance sheets. At December 31, 2010, we had commitments to fund approximately $1.9 million to the underlying partnerships. These commitments are not legally binding and may or may not be funded during the life of the partnerships. The amount of funding provided to the partnerships was de minimis in 2010, 2009, and 2008. We previously were the sole beneficiary of a special purpose entity that was a securitized asset trust holding forward contracts to purchase unrelated equity securities. The trust also held a defeasance swap contract for highly rated bonds to provide principal protection for the investments. There were no restrictions on the assets held in this trust, and the trust was free to dispose of the assets at any time. Because we intended to sell the investment, we recognized an other-than-temporary impairment loss of $23.7 million during the third quarter of 2009 and subsequently sold the investment in the following quarter for a realized investment gain of $2.1 million. Mortgage Loans Our mortgage loan portfolio is well diversified by both geographic region and property type to reduce risk of concentration. All of our mortgage loans are collateralized by commercial real estate. When issuing a new loan, our general policy is not to exceed a loan-to-value ratio, or the ratio of the loan balance to the estimated fair value of the underlying collateral, of 75 percent. We update the loan-to-value ratios at least every three years for each loan, and properties undergo a general inspection at least every two years. Our general policy for newly issued loans is to have a debt service coverage ratio greater than 1.25 times on a normalized 25 year amortization period. We update our debt service coverage ratios annually. Mortgage loans by property type and geographic region are as follows: (in millions of dollars) Carrying Amount Percent of Total Carrying Amount Percent of total December 31 2010 2009 Property Type Apartment Industrial Mixed Office Retail Other Total Region New England Mid-Atlantic East North Central West North Central South Atlantic East South Central West South Central Mountain Pacific Total 114 $ 33.7 2.2% $ 38.3 458.2 95.8 634.7 286.9 7.5 30.2 6.3 41.9 18.9 0.5 414.4 99.5 561.3 280.7 9.8 2.7% 29.5 7.1 40.0 20.0 0.7 $1,516.8 100.0% $1,404.0 100.0% $ 146.8 9.7% $ 152.4 10.9% 184.8 171.7 134.6 372.0 26.9 171.8 60.7 247.5 12.2 11.3 8.9 24.5 1.8 11.3 4.0 16.3 191.5 151.4 121.4 336.6 28.6 116.2 68.6 237.3 13.6 10.8 8.6 24.0 2.0 8.3 4.9 16.9 $1,516.8 100.0% $1,404.0 100.0% 4356_2010AR_Fin_ALL.indd 114 4/4/11 3:05 PM Unum 2010 Annual Report We evaluate each of our mortgage loans individually for impairment and assign an internal credit quality rating based on a comprehensive rating system used to evaluate the credit risk of the loan. The factors we use to derive our internal credit ratings may include the following: • Loan-to-value ratio • Debt service coverage ratio based on current operating income • Property location, including regional economics, trends and demographics • Age, condition, and construction quality of property • Current and historical occupancy of property • Lease terms relative to market • Tenant size and financial strength • Borrower’s financial strength • Borrower’s equity in transaction • Additional collateral, if any Although all available and applicable factors are considered in our analysis, loan-to-value and debt service coverage ratios are the most critical factors in determining whether we will initially issue the loan and also in assigning values and determining impairment. We assign an overall rating to each loan using an internal rating scale of Aa (highest quality) to Ba (lowest quality). We review and adjust, as needed, our internal credit quality ratings on an annual basis. This review process is performed more frequently for mortgage loans deemed to have a higher risk of delinquency. Mortgage loans, sorted by the applicable credit quality indicators, are as follows: (in millions of dollars) Internal Rating Aa A Baa Ba Total Loan-to-Value Ratio <= 65% > 65% <= 75% > 75% <= 85% > 85% <= 100% Total December 31, 2010 $ 19.0 744.4 732.9 20.5 $1,516.8 $ 425.3 869.2 161.9 60.4 $1,516.8 Based on an analysis of the above risk factors, as well as other current information, if we determine that it is probable we will be unable to collect all amounts due under the contractual terms of the mortgage loan, we establish an allowance for credit loss. If we expect to foreclose on the property, the amount of the allowance typically equals the excess carrying value of the mortgage loan over the fair value of the underlying collateral. If we expect to retain the mortgage loan until payoff, the allowance equals the excess carrying value of the mortgage loan over the expected future cash flows of the loan. The projection of future cash flows or a determination that the borrower can make the contractual payments is inherently subjective, and methodologies may vary depending on the circumstances specific to the loan. Additions and reductions to our allowance for credit losses on mortgage loans are reported as a component of net realized investment gains and losses. There have been no changes to our accounting policies or methodology from the prior period regarding estimating the allowance for credit losses on our mortgage loans. 4356_2010AR_Fin_ALL.indd 115 115 4/4/11 3:05 PM Notes To Consolidated Financial Statements The activity in the allowance for credit losses is as follows: (in millions of dollars) Allowance for Credit Losses Beginning Balance Provision Charge-offs, Net of Recoveries Ending Balance Unum 2010 Year Ended December 31 2010 2009 $ 3.2 2.4 (4.1) $ 1.5 $ — 5.5 (2.3) $ 3.2 There was no valuation allowance for credit losses at December 31, 2008 and no activity in the allowance during 2008.

As of December 31, 2010, none of our commercial mortgage loans were past due regarding principal and interest payments and none were on nonaccrual status. At December 31, 2010, we had $42.9 million in commitments to fund certain mortgage loans. These commitments are not legally binding and may or may not be funded. Transfers of Financial Assets To manage our cash position more efficiently, we enter into repurchase agreements with unaffiliated financial institutions. We generally use repurchase agreements as a means to finance the purchase of invested assets or for short-term general business purposes until projected cash flows become available from our operations or existing investments. Our repurchase agreements are typically outstanding for less than 30 days. We post collateral through our repurchase agreement transactions whereby the counterparty commits to purchase securities with the agreement to resell them to us at a later, specified date. The fair value of collateral posted is generally 102 percent of the cash received. Our investment policy also permits us to lend fixed maturity securities to unaffiliated financial institutions in short-term securities lending transactions. These transactions increase our investment income with minimal risk. Our securities lending policy requires that a minimum of 102 percent of the fair value of the securities loaned be maintained as collateral. Generally, cash is received as collateral under these agreements. In the event that securities are received as collateral, we are not permitted to sell or re-post them. We account for all of our securities lending transactions and repurchase agreements as collateralized financings. We had no securities lending transactions or repurchase agreements outstanding at December 31, 2010. 116 4356_2010AR_Fin_ALL.indd 116 4/4/11 3:05 PM Net Investment Income Sources for net investment income are as follows: (in millions of dollars) Fixed Maturity Securities Derivative Financial Instruments Mortgage Loans Policy Loans Other Long-term Investments Short-term Investments Gross Investment Income Less Investment Expenses Less Investment Income on PFA Assets Net Investment Income Unum 2010 Annual Report Year Ended December 31 2010 2009 2008 $2,401.9 $2,268.5 $2,277.0 17.2 91.1 13.9 15.2 3.2 13.5 81.0 12.4 11.5 6.9 15.1 72.0 13.0 15.5 40.7 2,542.5 2,393.8 2,433.3 28.2 18.8 29.2 18.0 25.8 18.5 $2,495.5 $2,346.6 $2,389.0 Realized Investment Gain and Loss Realized investment gains and losses reported in our consolidated statements of income are as follows: (in millions of dollars) Fixed Maturity Securities Gross Gains on Sales Gross Losses on Sales Other-Than-Temporary Impairment Loss Mortgage Loans and Other Invested Assets Gross Gains on Sales Gross Losses on Sales Impairment Loss Embedded Derivative in Modified Coinsurance Arrangement Other Derivatives Net Realized Investment Gain (Loss) Year Ended December 31 2010 2009 2008 $ 61.1 (41.3) (15.9) 7.9 (4.4) (3.8) 21.1 — $ 24.7 $ 48.6 (83.5) (211.8) 11.5 (0.4) (8.1) 243.1 12.3 $ 11.7 $ 64.9 (80.8) (151.1) 13.5 (3.8) (15.0) (291.7) (1.9) $(465.9) 4356_2010AR_Fin_ALL.indd 117 117 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 Note 4. Derivative Financial Instruments Purpose of Derivatives We are exposed to certain risks relating to our ongoing business operations. The primary risks managed by using derivative instruments are interest rate risk, risk related to matching duration for our assets and liabilities, and foreign currency risk. Historically, we have utilized current and forward interest rate swaps and options on forward interest rate swaps, current and forward currency swaps, forward treasury locks, currency forward contracts, and forward contracts on specific fixed income securities. Hedging transactions are primarily associated with our individual and group long-term care and individual and group disability products. All other product portfolios are periodically reviewed to determine if hedging strategies would be appropriate for risk management purposes. Our cash flow hedging programs are as follows: • Interest rate swaps are used to hedge interest rate risks and to improve the matching of assets and liabilities. An interest rate swap is an agreement in which we agree with other parties to exchange, at specified intervals, the difference between fixed rate and variable rate interest amounts. The purpose of these swaps is to hedge the anticipated purchase of fixed maturity securities thereby protecting us from the potential adverse impact of declining interest rates on the associated policy reserves. We also use interest rate swaps to hedge the potential adverse impact of rising interest rates in anticipation of issuing fixed rate long-term debt. • Foreign currency interest rate swaps have historically been used to hedge the currency risk of certain foreign currency-denominated fixed maturity securities owned for portfolio diversification and to hedge the currency risk associated with certain of the interest payments and debt repayments of the U.S. dollar-denominated debt issued by one of our U.K. subsidiaries. For hedges of fixed maturity securities, we agree to pay, at specified intervals, fixed rate foreign currency-denominated principal and interest payments in exchange for fixed rate payments in the functional currency of the operating segment. For hedges of debt issued, we agree to pay, at specified intervals, fixed rate foreign currency-denominated principal and interest payments to the counterparty in exchange for fixed rate U.S. dollar-denominated interest payments. • Options on forward interest rate swaps are used to hedge the interest rate risk on certain insurance liabilities with minimum interest rate guarantees. By purchasing options on interest rate swaps, we are able to lock in the minimum investment yields needed to meet the required interest rate guarantee on the insurance liabilities. • Forward treasury locks are used to minimize interest rate risk associated with the anticipated purchase or disposal of fixed maturity securities. A forward treasury lock is a derivative contract without an initial investment where we and the counterparty agree to purchase or sell a specific U.S. Treasury bond at a future date at a pre-determined price. • Foreign currency forward contracts are used to minimize foreign currency risks. A foreign currency forward is a derivative without an initial investment where we and the counterparty agree to exchange a specific amount of currencies, at a specific exchange rate, on a specific date. We use these forward contracts to hedge the foreign currency risk associated with certain of the debt repayments of the U.S. dollar-denominated debt issued by one of our U.K. subsidiaries and to hedge the currency risk of certain foreign currency- denominated fixed maturity securities owned for diversification purposes. Our fair value hedging programs are as follows: • Interest rate swaps are used to effectively convert certain of our fixed rate securities into floating rate securities which are used to fund our floating rate long-term debt. Under these swap agreements, we receive a variable rate of interest and pay a fixed rate of interest. Additionally, we use interest rate swaps to effectively convert certain fixed rate long-term debt into floating rate long-term debt. Under these swap agreements, we receive a fixed rate of interest and pay a variable rate of interest. 118 4356_2010AR_Fin_ALL.indd 118 4/4/11 3:05 PM Unum 2010 Annual Report Derivative Risks The basic types of risks associated with derivatives are market risk (that the value of the derivative will be adversely impacted by changes in the market, primarily the change in interest and exchange rates) and credit risk (that the counterparty will not perform according to the terms of the contract). The market risk of the derivatives should generally offset the market risk associated with the hedged financial instrument or liability. To help limit the credit exposure of the derivatives, we enter into master netting agreements with our counterparties whereby contracts in a gain position can be offset against contracts in a loss position. We also typically enter into bilateral, cross-collateralization agreements with our counterparties to help limit the credit exposure of the derivatives. These agreements require the counterparty in a loss position to submit acceptable collateral with the other counterparty in the event the net loss position meets or exceeds an agreed upon amount. Our current credit exposure on derivatives, which is limited to the value of those contracts in a net gain position less collateral held, was $14.8 million at December 31, 2010. We held cash collateral of $39.1 million and $24.9 million from our counterparties as of December 31, 2010 and 2009, respectively. This unrestricted cash collateral is included in short-term investments and the associated obligation to return the collateral to our counterparties is included in other liabilities in our consolidated balance sheets. We post either fixed maturity securities or cash as collateral to our counterparties. The carrying value of fixed maturity securities posted as collateral to our counterparties was $158.8 million and $123.1 million at December 31, 2010 and 2009, respectively. No cash was posted as collateral to our counterparties as of December 31, 2010 or 2009. The majority of our derivative instruments contain provisions that require us to maintain specified issuer credit ratings and financial strength ratings. Should our ratings fall below these specified levels, we would be in violation of the provisions, and our derivatives counterparties could terminate our contracts and request immediate payment. The aggregate fair value of all derivative instruments with credit risk-related contingent features that were in a liability position as of December 31, 2010 and 2009 was $199.6 million and $144.6 million, respectively. During 2008, we terminated certain of our outstanding derivatives when the credit ratings of the counterparty fell below our internal investment policy guidelines. At the time of termination, the contracts were in a loss position of $39.1 million. Consistent with our collateralization agreement, we had previously posted securities as collateral. During 2009, after further discussion with the counterparty it was determined that we would not receive the value of our collateral or pay the termination amount due to the counterparty. As a result, we were relieved of our previous liability and recorded a net realized investment loss of $2.3 million on the disposal of the securities posted as collateral. 4356_2010AR_Fin_ALL.indd 119 119 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 Hedging Activity The table below summarizes by notional amounts the activity for each category of derivatives.

As of December 31, 2010 and 2009, we had $617.9 million and $666.7 million, respectively, notional amount of open current and forward foreign currency swaps and foreign currency forwards to hedge fixed income foreign dollar-denominated securities. During 2010, we entered into $250.0 million notional amount of forward starting interest rate swaps used to hedge the interest rate risk associated with the anticipated issuance of long-term debt. The swaps were terminated in 2010 at the time the debt was issued. We recognized a loss of $18.5 million on the termination of these hedges. This loss was recognized in other comprehensive income and will be amortized into earnings as a component of interest and debt expense, which will have the effect of increasing the periodic interest expense on our debt issued in 2010. During 2010, we entered into $115.6 million notional amount of forward treasury locks used to minimize interest rate risk associated with the anticipated disposal of certain fixed maturity securities. The treasury locks were terminated in 2010 at the time the securities were called and/or sold. We recognized a loss of $1.0 million on the termination of these hedges. This loss was recognized as a component of net realized investment gain or loss or of net investment income. During 2009, we terminated certain currency swaps and forward currency contracts used to hedge the foreign currency risk associated with the U.S. dollar-denominated debt issued by one of our U.K. subsidiaries due in part to the improbability of the original forecasted transactions occurring during the time period originally anticipated and also to reduce our counterparty exposure for those transactions still anticipated to occur as originally forecasted. We recognized a gain of $56.3 million on the termination of these hedges, $42.0 million of 120 4356_2010AR_Fin_ALL.indd 120 4/4/11 3:05 PM Unum 2010 Annual Report which was recognized in other comprehensive income and $14.3 million as a component of net realized investment gain or loss. The debt associated with this hedge continues to be outstanding as of December 31, 2010. We previously owned certain principal protected equity linked trust certificates that contained an embedded derivative with a notional amount of $50.0 million as of December 31, 2008. This embedded derivative represented forward contracts that were accounted for as cash flow hedges. The purpose of these forward contracts was to hedge the risk of changes in cash flows related to the anticipated purchase of certain equity securities. The equity linked trust certificates were subsequently sold in 2009. For the year ended December 31, 2010, there was no material ineffectiveness related to our cash flow hedges. For the year ended December 31, 2009, we reclassified $12.3 million of net gains into earnings as a result of the discontinuance of cash flow hedges due to the improbability of the original forecasted transactions occurring during the time period originally anticipated. During 2010 and 2009, no component of the derivative instruments’ gain or loss was excluded from the assessment of hedge effectiveness. As of December 31, 2010, we expect to amortize approximately $30.0 million of net deferred gains on derivative instruments during the next twelve months. This amount will be reclassified from accumulated other comprehensive income into earnings and reported on the same income statement line item as the hedged item. The income statement line items that will be affected by this amortization are net investment income and interest and debt expense. The estimated amortization includes the impact of certain derivative contracts that have not yet been terminated as of December 31, 2010. Fluctuations in fair values of these derivatives between December 31, 2010 and the date of termination will vary our projected amortization. Amounts that will be reclassified from accumulated other comprehensive income into earnings to offset the earnings impact of foreign currency translation of hedged items are not estimable. As of December 31, 2010, we are hedging the variability of future cash flows associated with forecasted transactions through the year 2038. Fair Value Hedges As of December 31, 2010 and 2009, we had $174.0 million notional amount of receive variable, pay fixed interest rate swaps to hedge the changes in fair value of certain fixed rate securities held. These swaps effectively convert the associated fixed rate securities into floating rate securities, which are used to fund our floating rate long-term debt. Changes in the fair value of the derivative and changes in the fair value of the hedged item attributable to the risk being hedged are recognized in current earnings as a component of net realized investment gain or loss during the period of change in fair value. For the years ended December 31, 2010 and 2009, the change in fair value of the hedged fixed maturity securities attributable to the hedged benchmark interest rate resulted in a gain (loss) of $7.7 million and $(15.3) million, respectively, with an offsetting gain or loss on the related interest rate swaps. During 2010, we entered into a $350.0 million notional amount receive fixed, pay variable interest rate swap to hedge the changes in the fair value of certain fixed rate long-term debt. This swap effectively converts the associated fixed rate long-term debt into floating rate debt and provides for a better matching of interest rates with our short-term investments, which have frequent interest rate resets similar to a floating rate security. For the year ended December 31, 2010, the change in fair value of the hedged fixed debt attributable to the hedged benchmark interest rate resulted in a gain of $14.4 million, with an offsetting loss on the related interest rate swaps. For the years ended December 31, 2010 and 2009, there was no material ineffectiveness related to our fair value hedges, and no component of the derivative instruments’ gain or loss was excluded from the assessment of hedge effectiveness. There were no instances wherein we discontinued fair value hedge accounting due to a hedged firm commitment no longer qualifying as a fair value hedge. Derivatives Not Designated as Hedging Instruments We have an embedded derivative in a modified coinsurance arrangement for which we include in our realized investment gains and losses a calculation intended to estimate the value of the option of our reinsurance counterparty to cancel the reinsurance contract with us. However, neither party can unilaterally terminate the reinsurance agreement except in extreme circumstances resulting from regulatory supervision, delinquency proceedings, or other direct regulatory action. Cash settlements or collateral related to this embedded derivative are not required at any time during the reinsurance contract or at termination of the reinsurance contract. There are no credit-related counterparty triggers, and any accumulated embedded derivative gain or loss reduces to zero over time as the reinsured business winds down. 4356_2010AR_Fin_ALL.indd 121 121 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 Locations and Amounts of Derivative Financial Instruments The following tables summarize the location and fair values of derivative financial instruments, as reported in our consolidated balance sheets.

Interest accrued on prior year reserves has been calculated on the opening reserve balance less one-half year’s cash payments at our average reserve discount rate used during 2010, 2009, and 2008. “Incurred Related to Prior Years — All Other Incurred” declined in 2010 relative to the prior two years. The decrease relates primarily to an increased rate of claim recoveries for our group long-term disability and individual disability — recently issued lines of business in Unum US. Claim resolution rates are very sensitive to operational and environmental changes and can be volatile over short periods of time. Throughout the period 2008 to 2010, we had generally stable to improving claims management performance, and our claim resolution rates were fairly consistent with or slightly favorable to our long-term assumptions. Our claims management performance during 2010 for Unum US group long-term disability exceeded our long-term assumptions in regard to claim resolution rates. For the Unum US individual disability — recently issued line of business and the Individual Disability — Closed Block segment, the claims management performance in 2010 remained stable relative to 2009. Our claim resolution rate assumption used in determining reserves is our expectation of the resolution rate we will experience over the life of the block of business and will vary from actual experience in any one period, both favorably and unfavorably. 124 4356_2010AR_Fin_ALL.indd 124 4/4/11 3:05 PM Unum 2010 Annual Report A reconciliation of policy and contract benefits and reserves for future policy and contract benefits as reported in our consolidated balance sheets to the liability for unpaid claims and claim adjustment expenses is as follows: (in millions of dollars) Policy and Contract Benefits Reserves for Future Policy and Contract Benefits Total Less: Life Reserves for Future Policy and Contract Benefits Accident and Health Active Life Reserves Unrealized Adjustment to Reserves for Future Policy and Contract Benefits 2010 $ 1,565.0 39,715.0 December 31 2009 $ 1,736.9 37,740.8 41,280.0 39,477.7 7,380.7 6,451.6 3,108.3 7,247.5 5,999.8 1,644.7 2008 $ 1,769.5 34,581.5 36,351.0 7,128.4 5,606.7 (803.1) Liability for Unpaid Claims and Claim Adjustment Expenses $24,339.4 $24,585.7 $24,419.0 The unrealized adjustment to reserves for future policy and contract benefits reflects the changes that would be necessary to policyholder liabilities if the unrealized investment gains and losses related to the available-for-sale securities had been realized.

We are required to adjust deferred tax assets and liabilities through income on the date of enactment of a rate change. We recorded a reduction of $2.7 million to our income tax expense in the third quarter of 2010 to reflect the impact of the rate change on our net deferred tax liability related to our U.K. operations. We consider the unremitted earnings of our foreign operations to be permanently invested. The determination of a tax liability related to these earnings is not practicable. Our consolidated statements of income include the following changes in unrecognized tax benefits: (in millions of dollars) Balance at Beginning of Year Tax Positions Related to Prior Years Additions Subtractions Balance at End of Year Less Tax Attributable to Temporary Items Included Above Total Unrecognized Tax Benefits that if Recognized Would Affect the Effective Tax Rate 2010 $ 146.8 3.6 (11.5) 138.9 (123.7) December 31 2009 $ 149.8 8.5 (11.5) 146.8 (131.6) 2008 $ 161.0 0.3 (11.5) 149.8 (134.6) $ 15.2 $ 15.2 $ 15.2 Included in the balances at December 31, 2010, 2009, and 2008 are $123.7 million, $131.6 million, and $134.6 million, respectively, of unrecognized tax benefits for tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Other than potential interest and penalties, the disallowance of the shorter deductibility period would not affect our results of operations but would accelerate the payment of cash to the taxing authority to an earlier period. 4356_2010AR_Fin_ALL.indd 127 127 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 We recognize interest expense and penalties, if applicable, related to unrecognized tax benefits in tax expense net of federal income tax. The total amounts of accrued interest and penalties in our consolidated balance sheets as of December 31, 2010, 2009, and 2008 are $25.4 million, $19.9 million, and $13.4 million, respectively. We recognized interest related to unrecognized tax expense in our consolidated statements of income of $5.5 million, $6.5 million, and $5.9 million during 2010, 2009, and 2008, respectively. There were no changes to our uncertain tax positions as a result of settlements or lapses in statutes of limitations during 2010, 2009, and 2008. We file federal and state income tax returns in the United States and in foreign jurisdictions. We are under continuous examination by the Internal Revenue Service (IRS) with regard to our U.S. federal income tax returns. During 2010, the IRS completed its examination of tax years 2005 and 2006 and issued its revenue agent’s report (RAR) in December 2010. In January 2011, we filed a protest to the RAR with respect to all significant adverse proposed adjustments. During 2008, the IRS completed its examination of tax years 2002 through 2004 and issued its RAR. We filed a protest to the RAR in 2008 with respect to all significant adverse proposed adjustments. During 2009, we had a conference with the IRS with respect to our appeal of IRS audit adjustments for the years 1999 to 2004. Although we have not yet reached a final settlement with the IRS for these years, it is reasonably possible that this appeal will be resolved in whole or in part within 12 months and that statutes of limitations may expire in multiple jurisdictions within the same period. As a result, it is reasonably possible that our liability for unrecognized tax benefits could decrease within 12 months by $0 to $40.0 million. We believe sufficient provision has been made for all uncertain tax positions and that any adjustments by tax authorities with respect to such positions would not have a material adverse effect on our financial position, liquidity, or results of operations. Tax years subsequent to 2006 remain subject to examination by tax authorities in the U.S. Tax years subsequent to 2008 remain subject to examination in major foreign jurisdictions. We believe sufficient provision has been made for all proposed and potential adjustments for years that are not closed by the statute of limitations in all major tax jurisdictions and that any such adjustments would not have a material adverse effect on our financial position, liquidity, or results of operations. However, it is possible that the resolution of income tax matters could produce quarterly volatility in our results of operations in future periods. In March 2010, the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 were signed into law. Among other things, the new legislation reduces the tax benefits available to an employer that receives a postretirement prescription drug coverage subsidy from the federal government under the Medicare Prescription Drug, Improvement and Modernization Act of 2003. Under the new legislation, to the extent our future postretirement prescription drug coverage expenses are reimbursed under the subsidy program, the expenses covered by the subsidy will no longer be tax deductible after 2012. Employers that receive the subsidy must recognize the deferred tax effects relating to the future postretirement prescription drug coverage in the period the legislation was enacted. Our income tax expense for the year ended December 31, 2010 includes a non-cash tax charge of $10.2 million which was recorded in the first quarter of 2010 to reflect the impact of the tax law change. Included in 2009 operating results is a refund of interest of $0.3 million before tax and $0.2 million after tax attributable to tax year 1998. Included in 2008 operating results is a refund of interest of $7.6 million before tax and $4.9 million after tax primarily attributable to tax years 1986 through 1996. As of December 31, 2010, we had no net operating loss carryforward in the U.S. We held a valuation allowance of $4.1 million related to basis differences in foreign subsidiaries and net operating loss carryforwards in foreign jurisdictions because, in our judgment, we will most likely not realize a tax benefit for these amounts. The $0.1 million decrease in the valuation allowance during 2010 is due to the fluctuation in the British pound sterling to dollar exchange rate. Total income taxes paid net of refunds during 2010, 2009, and 2008 were $273.0 million, $381.6 million, and $369.0 million, respectively. 128 4356_2010AR_Fin_ALL.indd 128 4/4/11 3:05 PM Note 7.

The junior subordinated debt securities due 2038 are callable under limited, specified circumstances. The remaining callable debt may be redeemed, in whole or in part, at any time. The aggregate contractual principal maturities are $225.1 million in 2011, $296.9 million in 2015, and $2,349.5 million in 2016 and thereafter. Senior Secured Notes In 2007, Northwind Holdings, LLC (Northwind Holdings), a wholly-owned subsidiary of Unum Group, issued $800.0 million of insured, senior, secured notes due 2037 (the Northwind notes) in a private offering. The Northwind notes bear interest at a floating rate equal to the three-month LIBOR plus 0.78%. Northwind Holdings’ ability to meet its obligations to pay principal, interest, and other amounts due on the Northwind notes will be dependent principally on its receipt of dividends from Northwind Reinsurance Company (Northwind Re), the sole subsidiary of Northwind Holdings. Northwind Re reinsured the risks attributable to specified individual disability insurance policies issued by or reinsured by Provident Life and Accident Insurance Company, Unum Life Insurance Company of America (Unum America), and The Paul Revere Life Insurance Company (collectively, the ceding insurers) pursuant to separate reinsurance agreements between Northwind Re and each of the ceding insurers. The ability of Northwind Re to pay dividends to Northwind Holdings will depend on its satisfaction of applicable regulatory requirements and the performance of the reinsured policies. Recourse for the payment of principal, interest, and other amounts due on the Northwind notes is limited to the collateral for the Northwind notes and the other assets, if any, of Northwind Holdings. The collateral consists of a first priority, perfected security interest in (a) the debt service coverage account (Northwind DSCA) that Northwind Holdings is required to maintain in accordance with the indenture pursuant to which the Northwind notes were issued (the Northwind indenture), (b) the capital stock of Northwind Re and the dividends 4356_2010AR_Fin_ALL.indd 129 129 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 and distributions on such capital stock, and (c) Northwind Holdings’ rights under the transaction documents related to the Northwind notes to which Northwind Holdings is a party. At December 31, 2010 the amount in the Northwind DSCA was $9.0 million. None of Unum Group, the ceding insurers, Northwind Re, or any other affiliate of Northwind Holdings is an obligor or guarantor with respect to the Northwind notes. Northwind Holdings is required to repay a portion of the outstanding principal under the Northwind notes at par on the quarterly scheduled payment dates under the Northwind notes in an amount equal to the lesser of (i) a targeted amortization amount as defined in the Northwind indenture and (ii) the amount of the remaining available funds in the Northwind DSCA minus an amount equal to the minimum balance that is required to be maintained in the Northwind DSCA under the Northwind indenture, provided that Northwind Holdings has sufficient funds available to pay its other expenses, including interest payments on the Northwind notes, and to maintain the minimum balance in the Northwind DSCA as required under the Northwind indenture. During 2010, 2009, and 2008, Northwind Holdings made principal payments of $58.3 million, $48.0 million and $59.3 million, respectively, on the Northwind notes. In 2006, Tailwind Holdings, LLC (Tailwind Holdings), a wholly-owned subsidiary of Unum Group, issued $130.0 million of insured, senior, secured notes due 2036 (the Tailwind notes) in a private offering. The Tailwind notes bear interest at a floating rate equal to the three-month LIBOR plus 0.35%. Tailwind Holdings’ ability to meet its obligations to pay principal, interest, and other amounts due on the Tailwind notes will be dependent principally on its receipt of dividends from Tailwind Reinsurance Company (Tailwind Re), the sole subsidiary of Tailwind Holdings. Tailwind Re reinsured Unum America’s liability with respect to certain specified long-term disability claims incurred between January 1, 1999 and December 31, 2001 that were in payment status on January 1, 2006 pursuant to a reinsurance agreement between Tailwind Re and Unum America. The ability of Tailwind Re to pay dividends to Tailwind Holdings will depend on its satisfaction of applicable regulatory requirements and the performance of the reinsured claims. Recourse for the payment of principal, interest, and other amounts due on the Tailwind notes is limited to the collateral for the Tailwind notes and the other assets, if any, of Tailwind Holdings. The collateral consists of a first priority, perfected security interest in (a) the debt service coverage account (Tailwind DSCA) that Tailwind Re is required to maintain in accordance with the indenture pursuant to which the Tailwind notes were issued (the Tailwind indenture), (b) the capital stock of Tailwind Re and the dividends and distributions on such capital stock, and (c) Tailwind Holdings’ rights under the transaction documents related to the Tailwind notes to which Tailwind Holdings is a party. At December 31, 2010, the amount in the Tailwind DSCA was $12.0 million. None of Unum Group, Unum America, Tailwind Re, or any other affiliate of Tailwind Holdings is an obligor or guarantor with respect to the Tailwind notes. Tailwind Holdings is required to repay a portion of the outstanding principal under the Tailwind notes at par on the quarterly scheduled payment dates under the Tailwind notes in an amount equal to the lesser of (i) a targeted amortization amount as defined in the Tailwind indenture and (ii) the amount of the remaining available funds in the Tailwind DSCA minus an amount equal to the minimum balance that is required to be maintained in the Tailwind DSCA under the Tailwind indenture, provided that Tailwind Holdings has sufficient funds available to pay its other expenses, including interest payments on the Tailwind notes, and to maintain the minimum balance in the Tailwind DSCA as required under the Tailwind indenture. During 2010, 2009, and 2008, Tailwind Holdings made principal payments of $10.0 million each year on the Tailwind notes. Unsecured Notes In September 2010, we issued $400.0 million of unsecured senior notes in a public offering. In 2010, we purchased and retired $10.0 million of our 7.08% medium-term notes due 2024. In 2009, we issued $350.0 million of unsecured senior notes in a public offering. In 2009, we purchased and retired $1.2 million aggregate principal of our 7.19% medium-term notes due 2028 and $0.6 million aggregate principal of our 6.75% notes due 2028. In 2008, $36.6 million of the 6.85% senior debentures due 2015 were redeemed. These debentures were issued by UnumProvident Finance Company plc, a wholly-owned subsidiary of Unum Group, and are fully and unconditionally guaranteed by Unum Group. 130 4356_2010AR_Fin_ALL.indd 130 4/4/11 3:05 PM Unum 2010 Annual Report Fair Value Hedge During 2010, we entered into an interest rate swap to effectively convert our $350.0 million aggregate principal amount of 7.125% unsecured senior notes into floating rate debt. Under this agreement, we receive a fixed rate of interest and pay a variable rate of interest, based off of three-month LIBOR. The fair value adjustment of the swap resulted in a reduction of the carrying amount of the hedged debt of $14.4 million at December 31, 2010. Junior Subordinated Debt Securities In 1998, Provident Financing Trust I (the trust) issued $300.0 million of 7.405% capital securities in a public offering. These capital securities, which mature in 2038, are fully and unconditionally guaranteed by Unum Group, have a liquidation value of $1,000 per capital security, and have a mandatory redemption feature under certain circumstances. Unum Group issued 7.405% junior subordinated deferrable interest debentures to the trust in connection with the capital securities offering. The debentures mature in 2038. The sole assets of the trust are the junior subordinated debt securities. Short-term Debt In 2009, we purchased and retired the remaining $132.2 million of our outstanding 5.859% notes and repaid $58.3 million of reverse repurchase agreements outstanding at December 31, 2008. In 2008, we purchased and retired $17.8 million of our outstanding 5.859% notes and $175.0 million of our 5.997% notes. Interest and Debt Expense Interest paid on long-term and short-term debt and related securities during 2010, 2009, and 2008 was $140.7 million, $122.0 million, and $157.3 million, respectively. Shelf Registration We have a shelf registration, which became effective in December 2008, with the Securities and Exchange Commission to issue various types of securities, including common stock, preferred stock, debt securities, depository shares, stock purchase contracts, units and warrants, or preferred securities of wholly-owned finance trusts. The shelf registration enables us to raise funds from the offering of any individual security covered by the shelf registration as well as any combination thereof, subject to market conditions and our capital needs. 4356_2010AR_Fin_ALL.indd 131 131 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 Note 8. Pensions and Other Postretirement Benefits We sponsor several defined benefit pension and other postretirement benefit (OPEB) plans for our employees, including non-qualified pension plans. The U.S. plans comprise the majority of our total benefit obligation and benefit cost. We maintain a separate defined benefit plan for eligible employees in our U.K. operation. The U.K. defined benefit pension plan was closed to new entrants on December 31, 2002.

Assets for our U.S. pension plans include a diversified blend of domestic and international large cap, mid cap, and small cap equity securities, U.S. government and agencies, and corporate fixed income securities, private equity funds of funds, hedge funds of funds, and cash equivalents. The large cap and mid cap equity securities are comprised of equity index funds that are designed to track the Standard & Poor’s (S&P) 500 and S&P 400 Mid Cap indices, respectively. Small cap equity securities consist of individual equity securities as well as index funds that track the Russell 2000 index. International equity investments and emerging market equity investments consist of equity index funds that track the Morgan Stanley Capital International (MSCI) Europe Australasia Far East Index and the MSCI Emerging Markets Index, respectively. U.S. government and agency securities are comprised of treasury bonds and U.S. agency asset-backed securities. Corporate fixed income securities consist of investment-grade and below-investment-grade corporate bonds as well as certain asset- backed securities. Alternative investments, which include private equity funds of funds and hedge funds of funds, utilize proprietary strategies that tend to have a low correlation to the U.S. stock market. The target allocations for invested assets are 60 percent equity securities, 30 percent fixed income securities, and 10 percent alternative investments. Prohibited investments include, but are not limited to, unlisted securities, futures contracts, options, short sales, and investments in securities issued by the Company or its affiliates. Assets for our U.K. pension plan are primarily invested in a pooled fund consisting of diversified growth assets. The remaining assets in the U.K. plan are invested in a fixed-interest U.K. corporate bond fund and an index-linked U.K. government bond fund. The diversified growth fund is designed to generate a return that matches the U.K. Retail Price Index plus five percent over a five to seven year period. This fund is comprised primarily of domestic (U.K.) and international equity securities, emerging market fixed income securities, and a blend of investment-grade and below-investment-grade fixed income securities. Investment in fixed-interest U.K. corporate bonds is achieved through the ownership of a fund that primarily invests in corporate bonds with maturity dates greater than 10 years. Investment in U.K. index-linked bonds is achieved through ownership of a fund that traces the Financial Times Stock Exchange 5 year Index-linked Index. The target allocation for the assets is 60 percent equity securities and 40 percent fixed income securities. There are no categories of investments that are specifically prohibited by the U.K. plan, but there are general guidelines that ensure prudent investment action is taken. Such guidelines include the prevention of the plan from using derivatives for speculative purposes and limiting the concentration of risk in any one type of investment. Assets for life insurance benefits payable to certain former retirees covered under the OPEB plan are invested in life insurance contracts issued by one of our insurance subsidiaries. The terms of these contracts are consistent in all material respects with those the subsidiary offers to unaffiliated parties that are similarly situated. There are no categories of investments specifically prohibited by the OPEB plan. We believe our investment portfolios are well diversified by asset class and sector, with no potential risk concentrations in any one category. 134 4356_2010AR_Fin_ALL.indd 134 4/4/11 3:05 PM Unum 2010 Annual Report The categorization of fair value measurements by input level for the invested assets in our U.S. pension plans is as follows: (in millions of dollars) Invested Assets Equity Securities: U.S. Large Cap U.S. Mid Cap U.S. Small Cap International Emerging Markets Fixed Income Securities: U.S. Government and Agencies Corporate Alternative Investments: Private Equity Funds of Funds Hedge Funds of Funds Cash Equivalents Total (in millions of dollars) Invested Assets Equity Securities: U.S. Large Cap U.S. Mid Cap U.S. Small Cap International Emerging Markets Fixed Income Securities: U.S. Government and Agencies Corporate Alternative Investments: Private Equity Funds of Funds Hedge Funds of Funds Cash Equivalents Total December 31, 2010 Quoted Prices in Active Markets for Identical Assets or Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total $ — — 146.9 — — 119.9 69.5 — — 8.8 $243.5 98.1 50.7 191.2 64.0 9.7 113.7 — — — $ — $ 243.5 — — — — — — 15.0 46.0 — 98.1 197.6 191.2 64.0 129.6 183.2 15.0 46.0 8.8 $345.1 $770.9 $61.0 $1,177.0 December 31, 2009 Quoted Prices in Active Markets for Identical Assets or Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) $ — — 76.0 — — 68.1 56.1 — — 6.9 $198.4 82.1 65.7 125.9 41.0 13.0 106.6 — — — $207.1 $632.7 $ — — — — — — — 8.2 37.8 — $46.0 Total $198.4 82.1 141.7 125.9 41.0 81.1 162.7 8.2 37.8 6.9 $885.8 4356_2010AR_Fin_ALL.indd 135 135 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 Level 1 equity and fixed income securities consist of individual holdings and funds that are valued based on unadjusted quoted prices from active markets for identical securities. Level 2 equity securities consist of funds that are valued based on the net asset value (NAV) of the underlying holdings. These investments have no unfunded commitments and no specific redemption restrictions. Level 2 fixed income securities are valued using observable inputs through market corroborated pricing. Alternative investments are valued based on the NAV of the underlying holdings in a period ranging from one month to one quarter in arrears. We evaluate the need for adjustments to the NAV based on market conditions and discussions with fund managers in the period subsequent to the valuation date and prior to issuance of the financial statements. We made no adjustments to the NAV for 2010 or 2009. The hedge funds of funds have no redemption restrictions. The private equity funds of funds cannot be redeemed by investors, and distributions are received following the maturity of the underlying assets. It is estimated that these underlying assets will begin to mature between five and eight years from the date of initial investment.

The weighted average assumptions used in the measurement of our benefit obligations as of December 31 and our net periodic benefit costs for the years ended December 31 are as follows: Benefit Obligations Discount Rate Rate of Compensation Increase Net Periodic Benefit Cost Discount Rate Expected Return on Plan Assets Rate of Compensation Increase Pension Benefits U.S. Plans Non U.S. Plans OPEB 2010 2009 2010 2009 2010 2009 5.80% 4.00% 6.40% 7.50% 4.00% 6.40% 4.00% 6.40% 7.50% 4.00% 5.60% 4.50% 5.70% 6.90% 4.50% 5.70% 4.50% 6.40% 7.20% 5.10% 5.60% — 5.90% 5.75% — 5.90% — 6.10% 5.75% — We set the discount rate assumption annually for each of our retirement-related benefit plans at the measurement date to reflect the yield of a portfolio of high quality fixed income debt instruments matched against the projected cash flows for future benefits. Our long-term rate of return on plan assets assumption is an estimate, based on statistical analysis, of the average annual assumed return that will be produced from the plan assets until current benefits are paid. The market-related value equals the fair value of assets, determined as of the measurement date. Our expectations for the future investment returns of the asset categories were based on a combination of historical market performance and evaluations of investment forecasts obtained from external consultants and economists. The methodology underlying the return assumption included the various elements of the expected return for each asset class such as long-term rates of return, volatility of returns, and the correlation of returns between various asset classes. The expected return for the total portfolio was calculated based on the plan’s strategic asset allocation. Investment risk is measured and monitored on an ongoing basis through annual liability measurements, periodic asset/liability studies, and quarterly investment portfolio reviews. Risk tolerance is established through consideration of plan liabilities, plan funded status, and corporate financial condition. The expected return assumption for the life insurance reserve for our OPEB plan at December 31, 2010 and 2009 was 5.75 percent, which was based on full investment in fixed income securities with an average book yield of 6.21 percent in 2010 and 2009. Our rate of compensation increase assumption is generally based on periodic studies of compensation trends. For measurement purposes at December 31, 2010 and 2009, the annual rate of increase in the per capita cost of covered postretirement health care benefits assumed for the next calendar year was 9.00 percent for benefits payable to both retirees prior to Medicare eligibility as well as Medicare eligible retirees. The rate was assumed to change gradually to 5.00 percent by the end of 2019 and remain at that level thereafter. 138 4356_2010AR_Fin_ALL.indd 138 4/4/11 3:05 PM Unum 2010 Annual Report The medical and dental premium used to determine the per retiree employer subsidy are capped. If the cap is not reached by the year 2015, the caps are then set equal to the year 2015 premium. Certain of the current retirees and all future retirees are subject to the cap. Net Periodic Benefit Cost The following table provides the components of the net periodic benefit cost for the plans described above for the years ended December 31.

Our OPEB plan currently receives a subsidy from the federal government under the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the Medicare Act). This act allows an employer to choose whether to coordinate prescription drug benefits under a retiree medical plan with the Medicare prescription drug benefit or to keep the company plan design as it is and receive a subsidy from the federal government. When the Medicare Act became effective in 2006, we initially elected to receive the subsidy from the federal government with plans to defer our coordination with the new prescription drug benefit until a later date. This anticipated change was reflected in the net periodic benefit cost. In 2009, we amended the plan design to stop the deferral of coordination of benefits and elected to continue receiving the existing subsidy from the federal government. This election resulted in a $4.4 million prior service credit that began amortization in 2010. We received subsidy payments of $1.4 million and $1.2 million in 2010 and 2009, respectively. Our expected benefit payments in future years have been reduced by the amount of subsidy payments we expect to receive. The unrecognized net actuarial loss, prior service credit, and transition asset included in accumulated other comprehensive income and expected to be amortized and included in net periodic pension cost during 2011 is $31.4 million before tax and $20.4 million after tax. The prior service credit expected to be amortized and included as a reduction to net periodic cost for our OPEB plan during 2011 is $2.6 million before tax and $1.7 million after tax. 4356_2010AR_Fin_ALL.indd 139 139 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 Benefit Payments The following table provides expected benefit payments, which reflect expected future service, as appropriate. (in millions of dollars) U.S. Plans Non U.S. Plans Gross Subsidy Payments Net Pension Benefits OPEB Year 2011 2012 2013 2014 2015 2016 –2020 Funding Policy $ 27.9 31.0 34.9 39.6 44.5 323.3 $ 4.0 4.3 4.8 5.1 5.6 34.4 $15.5 15.9 16.3 16.6 16.7 80.7 $ 1.4 1.6 1.7 1.9 2.0 12.0 $14.1 14.3 14.6 14.7 14.7 68.7 The funding policy for our U.S. qualified defined benefit plan is to contribute annually an amount at least equal to the minimum annual contribution required under ERISA and other applicable laws, but generally not greater than the maximum amount that can be deducted for federal income tax purposes. We had no regulatory contribution requirements for 2010 and 2009; however, we elected to make voluntary contributions of $167.0 million and $70.0 million, respectively. We do not anticipate making any additional contributions to our U.S. plans during 2011. The funding policy for our U.S. non-qualified defined benefit pension plan is to contribute the amount of the benefit payments made during the year. Our expected return on plan assets and discount rate will not affect the cash contributions we are required to make to our U.S. pension and OPEB plans because we have met all minimum funding requirements required under ERISA. We contribute to our U.K. plan in accordance with a schedule of contributions which requires us to contribute to the plan at the rate of at least 15.0 percent of employee salaries sufficient to meet the minimum funding requirement under U.K. legislation. We made contributions of $5.0 million and $5.5 million in 2010 and 2009, respectively, or approximately £3.2 million and £3.5 million. We expect to make contributions of £3.2 million during 2011. Our OPEB plan represents a non-vested, non-guaranteed obligation, and current regulations do not require specific funding levels for these benefits, which are comprised of retiree life, medical, and dental benefits. It is our practice to use general assets to pay medical and dental claims as they come due in lieu of utilizing plan assets for the medical and dental benefit portions of our OPEB plan. 140 4356_2010AR_Fin_ALL.indd 140 4/4/11 3:05 PM Unum 2010 Annual Report Note 9. Stockholders’ Equity and Earnings Per Common Share Common Stock In May 2010, our board of directors authorized the repurchase of up to $500.0 million of Unum Group’s common stock. During 2010, we repurchased 16.4 million shares, at a cost of $356.0 million, including commissions of $0.3 million, under this share repurchase program. The dollar value of shares remaining under this program, which had an expiration date of May 2011, was $144.3 million at December 31, 2010. On February 2, 2011, our board of directors authorized the repurchase of up to $1.0 billion of Unum Group’s common stock, in addition to the amount remaining to be repurchased under the previous authorization discussed above. The $1.0 billion share repurchase program has an expiration date of August 2012. On February 4, 2011, we repurchased 7.1 million shares, at a cost of $200.0 million, using an accelerated repurchase agreement with a financial counterparty. As part of this transaction, we simultaneously entered into a forward contract indexed to the price of Unum Group common stock, which subjects the transaction to a future price adjustment. Under the terms of the repurchase agreement, we may receive, or be required to pay, a price adjustment based on the volume weighted average price of Unum Group common stock during the term of the agreement, less a discount. Any price adjustment payable to us will be settled in shares of Unum Group common stock. Any price adjustment we are required to pay will be settled in either cash or common stock at our option. We expect the price adjustment to settle on or before the completion of the accelerated repurchase agreement in April 2011. The shares repurchased pursuant to the accelerated repurchase agreement completed the $500.0 million repurchase authorization and initiated the $1.0 billion repurchase program. During 2007, our board of directors authorized the repurchase of up to $700.0 million of Unum Group’s common stock. During 2008, we repurchased $700.0 million or 29.9 million shares of common stock under this share repurchase program. The shares repurchased prior to and through December 31, 2010 will be held in treasury until such time as they may be reissued or retired and are reflected as treasury stock in our consolidated balance sheets. The shares repurchased using the accelerated repurchase agreement were retired as of February 4, 2011. Preferred Stock Unum Group has 25,000,000 shares of preferred stock authorized with a par value of $0.10 per share. No preferred stock has been issued to date. Earnings Per Common Share Net income per common share is determined as follows: (in millions of dollars, except share data) Numerator Net Income Denominator (000s) Weighted Average Common Shares — Basic Dilution for Assumed Exercises of Stock Options and Nonvested Stock Awards Year Ended December 31 2010 2009 2008 $886.1 $852.6 $553.2 325,839.0 331,266.2 341,022.8 1,382.1 870.0 537.5 Weighted Average Common Shares — Assuming Dilution 327,221.1 332,136.2 341,560.3 Net Income Per Common Share Basic Assuming Dilution $ 2.72 $ 2.71 $ 2.57 $ 2.57 $ 1.62 $ 1.62 4356_2010AR_Fin_ALL.indd 141 141 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 We use the treasury stock method to account for the effect of outstanding stock options, nonvested stock awards, and performance restricted stock units on the computation of dilutive earnings per share. Under this method, these potential common shares will each have a dilutive effect, as individually measured, when the average market price of Unum Group common stock during the period exceeds the exercise price of the stock options, the grant price of the nonvested stock awards, and/or the threshold stock price of performance restricted stock units. For further discussion of stock-based awards see Note 10. The outstanding stock options have exercise prices ranging from $11.37 to $32.08, the nonvested stock awards have grant prices ranging from $10.59 to $25.53, and the performance restricted stock units have a threshold stock price of $26.00. In computing earnings per share assuming dilution, only potential common shares that are dilutive (those that reduce earnings per share) are included. Potential common shares not included in the computation of dilutive earnings per share because their impact would be antidilutive, based on current market prices, approximated 3.5 million, 7.1 million, and 8.3 million shares of common stock for the years ended December 31, 2010, 2009, and 2008, respectively. Note 10. Stock-Based Compensation Description of Stock Plans Under the stock incentive plan of 2007, up to 35.00 million shares of common stock are available for awards to our employees, officers, consultants, and directors. Awards may be in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, and other stock-based awards. Each full value award, defined as any award other than a stock option or stock appreciation right, is counted as 2.7 shares. The exercise price for stock options issued cannot be less than the fair market value of the underlying common stock as of the grant date. Stock options have a maximum term of ten years after the date of grant and generally vest after three years. At December 31, 2010, approximately 20.48 million shares were available for future grants. Under the broad-based stock plan of 2001, up to 2.00 million shares of common stock were available for stock option awards to our employees, officers, consultants, and brokers, excluding certain senior officers and directors. The plan was terminated in December 2007 for purposes of any further grants, other than reload grants, for which 20,000 shares were available at December 31, 2010. The stock options have a maximum term of ten years after the date of grant and generally vest after three years. Under the stock plan of 1999, comprised of the Provident Companies, Inc. stock plan of 1999 and the UnumProvident Corporation stock plan of 1999, an aggregate of up to 17.50 million shares of common stock were available for awards to our employees, officers, brokers, and directors. Awards could be in the form of stock options, stock appreciation rights, stock awards, dividend equivalent awards, or any other right or interest relating to stock. The plan was terminated in May 2007 for purposes of any further grants, other than reload grants, for which 250,000 shares were available at December 31, 2010. Stock options have a maximum term of ten years after the date of grant and generally vest after three years. Substantially all of our employees are eligible to participate in an employee stock purchase plan (ESPP). Under the plan, up to 3.46 million shares of common stock are authorized for issuance, of which approximately 1.08 million remain available for issuance at December 31, 2010. Stock may be purchased at the end of each financial quarter at a purchase price of 85 percent of the market price. We sold 150,879 shares, 232,962 shares, and 148,490 shares to employees with a weighted average grant date fair value of $3.47, $4.13, and $5.72, during the years 2010, 2009, and 2008, respectively. We issue new shares of common stock for nonvested stock grants, exercise of stock options, and purchase of ESPP shares. 142 4356_2010AR_Fin_ALL.indd 142 4/4/11 3:05 PM Unum 2010 Annual Report Nonvested Stock Awards Activity for nonvested stock awards classified as equity is as follows: Nonvested at December 31, 2009 Granted Vested Forfeited Nonvested at December 31, 2010 Shares (000s) Weighted Average Grant Date Fair Value 2,420 856 (1,108) (69) 2,099 $15.62 20.91 17.19 16.02 16.85 Stock awards vest over a one to three year service period, beginning at the date of grant, and the compensation cost is recognized ratably during the vesting period. Compensation cost for stock awards subject to accelerated vesting upon retirement is recognized over the implicit service period. Forfeitable dividend equivalents on nonvested stock awards are accrued in the form of additional restricted stock units. The weighted average grant date fair values per share for nonvested stock awards granted during 2010, 2009, and 2008 were $20.91, $12.32, and $23.66, respectively. The total fair value of shares vested during 2010, 2009, and 2008 was $19.0 million, $17.5 million, and $11.3 million, respectively. At December 31, 2010, we had $12.6 million of unrecognized compensation cost related to nonvested stock awards that will be recognized over a weighted average period of 0.8 years. Cash-Settled Awards Cash-settled awards vest over a three year service period, beginning at the date of grant, and the compensation cost is recognized ratably during the vesting period. Compensation cost for stock awards subject to accelerated vesting upon retirement is recognized over the implicit service period. Forfeitable dividend equivalents on nonvested cash-settled awards are accrued in the form of additional units. During 2010, we granted 100,445 units which will be settled in cash ratably over a three year period on the anniversary of the award. The amount payable per unit awarded will be equal to the price per share of Unum Group’s common stock at settlement of the award, and as such, we measure the value of the award each reporting period based on the current stock price. The effects of changes in the stock price during the service period are recognized as compensation cost over the service period. Changes in the amount of the liability due to stock price changes after the service period are compensation cost of the period in which the changes occur. The cash-settled awards granted during 2010 had a weighted average grant date fair value per unit of $20.79. At December 31, 2010, we had 101,695 units outstanding, including dividend equivalent units. There is no unrecognized compensation cost related to the 2010 cash-settled awards, other than future changes in the liability due to future stock price changes, as the units do not require additional future service. Performance Restricted Stock Units (PRSUs) PRSU activity is summarized as follows: PRSUs at December 31, 2009 Dividends Forfeited PRSUs at December 31, 2010 Shares (000s) Weighted Average Grant Date Fair Value 1,172 19 (48) 1,143 $16.06 21.44 16.10 16.15 In September 2007, we issued approximately 1.25 million PRSUs with a grant date fair value of $15.99. Vesting for this grant is contingent upon meeting various company threshold performance and stock price conditions. Forfeitable dividend equivalents on PRSUs are accrued in the form of additional restricted stock units. The weighted average grant date fair values per share for PRSU grants and dividends during 2010, 2009, and 2008 were $21.44, $15.95, and $19.08, respectively. All PRSUs outstanding at December 31, 2010 were nonvested. 4356_2010AR_Fin_ALL.indd 143 143 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 At December 31, 2010, we had $0.5 million of unrecognized compensation cost related to PRSUs that will be recognized over a weighted average period of 0.5 years. The PRSU expense and unrecognized compensation cost assume the performance goals are attained at 100 percent. Actual performance may result in zero to 100 percent of the units ultimately being earned. We use the accelerated method of amortization for recognizing compensation expense, which treats each of the three vesting tranches as a separate award over the expected life of the unit. We estimated the fair value on the date of initial grant using the Monte-Carlo model. The following assumptions were used to value the grant: • Expected volatility of 29 percent, based on our historical daily stock prices. • Expected life of 4.4 years, which equals the maximum term. • Expected dividend yield of 1.24 percent, based on the dividend rate at the date of grant. • Risk free interest rate of 3.97 percent, based on the yield of treasury bonds at the date of grant. Stock Options Stock option activity is summarized as follows: Outstanding at December 31, 2009 Granted Exercised Expired Outstanding at December 31, 2010 Exercisable at December 31, 2010 Shares (000s) 5,673 269 (489) (2,096) 3,357 2,645 Remaining Intrinsic Weighted Average Contractual Exercise Price Term Value (000s) $24.21 20.78 14.14 28.75 22.58 $23.92 2.5 years $10,914 1.4 years $ 6,195 All outstanding stock options at December 31, 2010 are expected to vest. Stock options vest over a three year service period, beginning at the date of grant, and the compensation cost is recognized ratably during the vesting period. The total intrinsic value of options exercised during 2010, 2009, and 2008 was $3.2 million, $2.6 million, and $1.0 million, respectively. The total fair value of options that vested during 2010, 2009, and 2008 was $2.5 million, $2.0 million, and $0.5 million, respectively. At December 31, 2010, we had $0.5 million of unrecognized compensation cost related to stock options that will be recognized over a weighted average period of 0.7 years. The weighted average grant date fair value of options granted during 2010, 2009, and 2008 was $9.04, $4.45, and $8.84, respectively. We estimated the fair value on the date of grant using the Black-Scholes valuation model. The following assumptions were used to value the 2010, 2009, and 2008 grants: • Expected volatility of 55 percent, 50 percent, and 43 percent, respectively, based on our historical daily stock prices. • Expected life of 5.0 years, based on historical average years to exercise. • Expected dividend yield of 1.59 percent, 1.68 percent, and 1.30 percent, respectively, based on the dividend rate at the date of grant. • Risk free interest rate of 2.33 percent, 1.89 percent, and 2.93 percent, respectively, based on the yield of treasury bonds at the date of grant. 144 4356_2010AR_Fin_ALL.indd 144 4/4/11 3:05 PM Unum 2010 Annual Report Expense Compensation expense for the stock plans, as reported in our consolidated statements of income, is as follows: (in millions of dollars) Nonvested Stock Awards and Cash-Settled Awards Performance Restricted Stock Units Stock Options Employee Stock Purchase Plan Total Compensation Expense, Before Income Tax Total Compensation Expense, Net of Income Tax Year Ended December 31 2010 $20.7 1.5 2.5 0.5 $25.2 $17.2 2009 $22.4 6.8 3.7 1.0 $33.9 $22.0 2008 $18.3 6.7 2.9 0.9 $28.8 $18.7 Cash received under all share-based payment arrangements for the years ended December 31, 2010, 2009, and 2008 was $10.0 million, $8.0 million, and $4.4 million, respectively. Note 11. Reinsurance Our reinsurance recoverable at December 31, 2010 relates to 93 companies. Fourteen major companies account for approximately 91 percent of our reinsurance recoverable at December 31, 2010, and are all companies rated A or better by A.M. Best Company (AM Best) or are fully securitized by letters of credit or investment-grade fixed maturity securities held in trust. Of the remaining reinsurance recoverable, approximately eight percent relates to business reinsured either with companies rated A- or better by AM Best, with overseas entities with equivalent ratings or backed by letters of credit or trust agreements, or through reinsurance arrangements wherein we retain the assets in our general account. Approximately one percent of our reinsurance recoverable is held by companies either rated below A- by AM Best or not rated.

As a result of the assumption, we received cash of £24.5 million, recorded £0.4 million in accrued premiums receivable, assumed reserves of £22.2 million (approximately $44.2 million), and recorded a deferred gain of £2.7 million. 4356_2010AR_Fin_ALL.indd 145 145 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 Note 12. Segment Information We have three major business segments: Unum US, Unum UK, and Colonial Life. Our other segments are the Individual Disability — Closed Block segment and the Corporate and Other segment. The Unum US segment includes insurance for group long-term and short-term disability, group life and accidental death and dismemberment, and supplemental and voluntary lines of business. The supplemental and voluntary lines of business are comprised of recently issued disability insurance, group and individual long-term care insurance, and voluntary benefits products. These products are marketed through our field sales personnel who work in conjunction with independent brokers and consultants. The Unum UK segment includes insurance for group long-term disability, group life, and supplemental and voluntary lines of business. The supplemental and voluntary lines of business are comprised of individual disability, group and individual critical illness, and voluntary benefits products. Unum UK’s products are sold primarily in the United Kingdom through field sales personnel and independent brokers and consultants. The Colonial Life segment includes insurance for accident, sickness, and disability products, life products, and cancer and critical illness products marketed to employees at the workplace through an agency sales force and brokers. The Individual Disability — Closed Block segment generally consists of those individual disability policies in-force before the substantial changes in product offerings, pricing, distribution, and underwriting, which generally occurred during the period 1994 through 1998. A small amount of new business continued to be sold after these changes, but we stopped selling new policies in this segment at the beginning of 2004 other than update features contractually allowable on existing policies. The Corporate and Other segment includes investment income on corporate assets not specifically allocated to a line of business, interest expense on corporate debt other than non-recourse debt, and certain other corporate income and expense not allocated to a line of business. Corporate and Other also includes results from certain Unum US insurance products not actively marketed, including individual life and corporate-owned life insurance, reinsurance pools and management operations, group pension, health insurance, and individual annuities. In the following segment financial data, “operating revenue” excludes net realized investment gains and losses. “Operating income” or “operating loss” excludes net realized investment gains and losses and income tax. These are considered non-GAAP financial measures. These non-GAAP financial measures of “operating revenue” and “operating income” or “operating loss” differ from revenue and income before income tax as presented in our consolidated statements of income prepared in accordance with GAAP due to the exclusion of before-tax realized investment gains and losses. We measure segment performance excluding realized investment gains and losses because we believe that this performance measure is a better indicator of the ongoing businesses and the underlying trends in the businesses. Our investment focus is on investment income to support our insurance liabilities as opposed to the generation of realized investment gains and losses, and a long-term focus is necessary to maintain profitability over the life of the business. Realized investment gains and losses depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our segments. However, income or loss excluding realized investment gains and losses does not replace net income or net loss as a measure of overall profitability. We may experience realized investment losses, which will affect future earnings levels since our underlying business is long-term in nature and we need to earn the assumed interest rates in our liabilities. 146 4356_2010AR_Fin_ALL.indd 146 4/4/11 3:05 PM Unum 2010 Annual Report A reconciliation of total operating revenue and operating income by segment to revenue and net income as reported in our consolidated statements of income follows: (in millions of dollars) Operating Revenue by Segment Net Realized Investment Gain (Loss) Revenue Operating Income by Segment Net Realized Investment Gain (Loss) Income Tax Net Income Year Ended December 31 2010 2009 2008 $10,168.5 $10,079.3 $10,448.2 24.7 11.7 (465.9) $10,193.2 $10,091.0 $ 1,306.6 $ 1,280.6 24.7 445.2 11.7 439.7 $ 9,982.3 $ 1,289.9 (465.9) 270.8 $ 886.1 $ 852.6 $ 553.2 Premium income by major line of business within each of our segments is presented as follows.

At December 31, 2010 and 2009, goodwill was $201.2 million and $201.6 million, respectively, with $190.0 million attributable to Unum US and the remainder attributable to Unum UK. The decrease during 2010 is due entirely to the fluctuation in the British pound sterling to dollar exchange rate. Stockholders’ equity is allocated to the operating segments on the basis of an internal allocation formula that reflects the volume and risk components of each operating segment’s business and aligns allocated equity with our target capital levels for regulatory and rating agency purposes. We modify this formula periodically to recognize changes in the views of capital requirements. Note 13. Commitments and Contingent Liabilities Commitments We have noncancelable lease obligations on certain office space and equipment. As of December 31, 2010, the aggregate net minimum lease payments were $220.1 million payable as follows: $25.8 million in 2011, $25.1 million in 2012, $22.9 million in 2013, $19.8 million in 2014, $15.6 million in 2015, and $110.9 million thereafter. Rental expense for the years ended December 31, 2010, 2009, and 2008 was $29.3 million, $30.1 million, and $34.5 million, respectively. At December 31, 2010, we had unfunded commitments of $73.0 million for certain of our private equity partnerships, $1.9 million for underlying partnerships in our investment in a special purpose entity, $29.9 million for certain private placement fixed maturity securities, and $42.9 million for certain mortgage loans. The funds are not legally binding at December 31, 2010 and may or may not be funded during the term of the investments. In addition, we have a legally binding unfunded commitment of $169.9 million, which is recognized as a liability in our consolidated balance sheets, to fund tax credit partnership investments. Contingent Liabilities We are a defendant in a number of litigation matters. In some of these matters, no specified amount is sought. In others, very large or indeterminate amounts, including punitive and treble damages, are asserted. There is a wide variation of pleading practice permitted in the United States courts with respect to requests for monetary damages, including some courts in which no specified amount is required and others which allow the plaintiff to state only that the amount sought is sufficient to invoke the jurisdiction of that court. Further, some jurisdictions permit plaintiffs to allege damages well in excess of reasonably possible verdicts. Based on our extensive experience and that of others in the industry with respect to litigating or resolving claims through settlement over an extended period of time, we believe that the monetary damages asserted in a lawsuit or claim bear little relation to the merits of the case, or the likely disposition value. Therefore, the specific monetary relief sought is not stated. Unless indicated otherwise in the descriptions below, reserves have not been established for litigation and contingencies. An estimated loss is accrued when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In the disclosures that follow about litigation, we refer to the name of the company specified in the original complaint, following the practice in the courts. Therefore, references to UnumProvident Corporation should be understood as references to Unum Group. 150 4356_2010AR_Fin_ALL.indd 150 4/4/11 3:05 PM Unum 2010 Annual Report Claims Handling Matters We and our insurance subsidiaries, as part of our normal operations in managing disability claims, are engaged in claim litigation where disputes arise as a result of a denial or termination of benefits. Most typically these lawsuits are filed on behalf of a single claimant or policyholder, and in some of these individual actions punitive damages are sought, such as claims alleging bad faith in the handling of insurance claims. For our general claim litigation, we maintain reserves based on experience to satisfy judgments and settlements in the normal course. We expect that the ultimate liability, if any, with respect to general claim litigation, after consideration of the reserves maintained, will not be material to our consolidated financial condition. Nevertheless, given the inherent unpredictability of litigation, it is possible that an adverse outcome in certain claim litigation involving punitive damages could, from time to time, have a material adverse effect on our consolidated results of operations in a period, depending on the results of operations for the particular period. From time to time class action allegations are pursued where the claimant or policyholder purports to represent a larger number of individuals who are similarly situated. Since each insurance claim is evaluated based on its own merits, there is rarely a single act or series of actions, which can properly be addressed by a class action. Nevertheless, we monitor these cases closely and defend ourselves appropriately where these allegations are made. Broker Compensation, Quoting Process, and Other Matters Examinations and Investigations In November 2009, we were contacted by Florida state insurance regulators to discuss a resolution of their investigation of our compliance with state and federal laws with respect to producer compensation, solicitation activities, policies sold to state or municipal entities, and information regarding compensation arrangements with brokers. This investigation commenced in 2005, and, until this most recent contact, we had received no communications from the regulators regarding this matter since December 2007. Broker-Related Litigation We and certain of our subsidiaries, along with many other insurance brokers and insurers, have been named as defendants in a series of putative class actions that have been transferred to the U.S. District Court for the District of New Jersey for coordinated or consolidated pretrial proceedings as part of multidistrict litigation (MDL) No. 1663, In re Insurance Brokerage Antitrust Litigation. The plaintiffs in MDL No. 1663 filed a consolidated amended complaint in August 2005, which alleges, among other things, that the defendants violated federal and state antitrust laws, the Racketeer Influenced Corrupt Organizations Act (RICO), ERISA, and various state common law requirements by engaging in alleged bid rigging and customer allocation and by paying undisclosed compensation to insurance brokers to steer business to defendant insurers. Defendants filed a motion to dismiss the complaint on November 29, 2005. On April 5, 2007, defendants’ motion to dismiss was granted without prejudice as to all counts except the ERISA counts. Plaintiffs were granted a last opportunity to file an amended complaint, and they did so on May 22, 2007. On August 31, 2007 and September 28, 2007, plaintiffs’ federal antitrust and RICO claims were dismissed with prejudice. Defendants’ motion for summary judgment on the ERISA counts was granted on January 14, 2008. All pending state law claims were dismissed without prejudice. Plaintiffs filed an appeal with the Third Circuit Court of Appeals of the order dismissing their federal antitrust and RICO claims. On August 16, 2010, the Third Circuit Court of Appeals affirmed the dismissal with prejudice of plaintiff’s federal antitrust and RICO claims against us and certain of our subsidiaries. On September 27, 2010, the District Court entered final judgment against plaintiffs and in favor of defendants, including us and certain of our subsidiaries. We are a defendant in an action styled, Palm Tree Computers Systems, Inc. v. ACE USA, et al., which was filed in the Florida state Circuit Court on February 16, 2005. The complaint contains allegations similar to those made in the multidistrict litigation referred to above. The case was removed to federal court and, on October 20, 2005, the case was transferred to the District of New Jersey multidistrict litigation. Plaintiffs renewed a motion to remand the case to the state court in Florida, and that motion was denied without prejudice. 4356_2010AR_Fin_ALL.indd 151 151 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 Miscellaneous Matters In September 2003, United States of America ex. rel. Patrick J. Loughren v. UnumProvident Corporation and GENEX Services, Inc. (GENEX) was filed in the United States District Court for the District of Massachusetts. This is a qui tam action to recover damages and civil penalties on behalf of the United States of America alleging violations of the False Claims Act by us and our former GENEX subsidiary. In accordance with the False Claims Act, the action was originally filed under seal to provide the government the opportunity to investigate the allegations and prosecute the action if they believed that the case had merit and warranted their attention. The government declined to prosecute the case, and the case became a matter of public record on December 23, 2004. The complaint alleged that we defrauded the government by inducing and or assisting disability claimants to apply for disability benefits from the Social Security Administration (SSA) when we allegedly knew that the claimants were not disabled under SSA criteria. Relator identified 95 individual claims that he alleged to be false and sought to present expert testimony from a statistician who would say that each of those claims found to be false could be extrapolated to support a finding of a much larger number of false claims. We filed a motion for summary judgment which was denied on September 15, 2008. The case proceeded to trial at which seven out of the 95 claims were adjudicated. We prevailed on four of the claims, the Relator prevailed on two of the claims, and the jury could not reach a verdict on one of the claims. The jury awarded the Relator $850 in damages which was trebled. The court also assessed a penalty of $11,000 for each of the two claims. On February 24, 2009, the court also ruled that the testimony of the Relator’s expert in support of extrapolation would be excluded. We filed an appeal with the First Circuit Court of Appeals on the two claims which Relator prevailed. On July 29, 2010, the Court of Appeals vacated the jury verdict on the two claims and remanded the case to the trial court. On August 12, 2010, we filed a petition with the First Circuit Court of Appeals seeking clarification and/or rehearing en banc of the court’s July 29, 2010 opinion. On October 7, 2010, this petition was denied without comment and the case was remanded back to the trial court. An estimate of the liability to resolve this matter was established in the fourth quarter of 2010. This accrual was not material to our operating results. In September 2008, we received service of a complaint, in an adversary proceeding in connection with the bankruptcy case In re Quebecor World (USA) Inc., et al. entitled Official Committee of Unsecured Creditors of Quebecor World (USA) Inc., et al., v. American United Life Insurance Company, et al., filed in the United States Bankruptcy Court for the Southern District of New York. The complaint alleges that we received preference payments relating to notes held by certain of our insurance subsidiaries and seeks to avoid and recover such payments plus interest and cost of the action. We deny the allegations in the complaint and will vigorously contest them. In July 2010, we received a subpoena from the Office of the New York Attorney General requesting documents and information relating to certain group life insurance policies wherein we paid life insurance proceeds by establishing interest-bearing retained asset accounts. We are cooperating with the investigation. In October 2010, Denise Merrimon, Bobby S. Mowery, and all others similarly situated vs. Unum Life Insurance Company of America, was filed in the United States District Court for the District of Maine. This is a putative class action alleging that we breached fiduciary duties owed to certain beneficiaries under certain group life insurance policies when we paid life insurance proceeds by establishing interest- bearing retained asset accounts rather than by mailing checks. Plaintiffs seek to represent a class of beneficiaries under group life insurance contracts that were employee welfare benefit plans under ERISA and under which we paid death benefits pursuant to a retained asset account. Plaintiffs seek to recover on behalf of the class the difference between the interest paid to them and amounts alleged to have been realized by us through our investment of the retained assets. We intend to vigorously defend the action. 152 4356_2010AR_Fin_ALL.indd 152 4/4/11 3:05 PM Unum 2010 Annual Report Summary Various lawsuits against us, in addition to those discussed above, have arisen in the normal course of business. Further, state insurance regulatory authorities and other federal and state authorities regularly make inquiries and conduct investigations concerning our compliance with applicable insurance and other laws and regulations. Given the complexity and scope of our litigation and regulatory matters, it is not possible to predict the ultimate outcome of all pending investigations or legal proceedings or provide reasonable estimates of potential losses, except where noted in connection with specific matters. It is possible that our results of operations or cash flows in a particular period could be materially affected by an ultimate unfavorable outcome of pending litigation or regulatory matters depending, in part, on our results of operations or cash flows for the particular period. We believe, however, that the ultimate outcome of all pending litigation and regulatory matters, after consideration of applicable reserves and rights to indemnification, should not have a material adverse effect on our financial position. Note 14. Statutory Financial Information Statutory Net Income, Capital and Surplus, and Dividends Statutory net income for U.S. life insurance companies is reported in conformity with statutory accounting principles prescribed by the NAIC and adopted by applicable domiciliary state laws. The commissioners of the states of domicile have the right to permit other specific practices that may deviate from prescribed practices. For the years ended December 31, 2010, 2009, or 2008, none of the states of domicile for our U.S. insurance subsidiaries had adopted accounting practices that differed materially from statutory accounting principles prescribed by the NAIC. The statutory operating results of our traditional U.S. insurance subsidiaries, which exclude Tailwind Re and Northwind Re, as well as the statutory results for these two special purpose financial captive U.S. insurance subsidiaries, are as follows: (in millions of dollars) Combined Net Income U.S. Traditional Insurance Subsidiaries Tailwind Re and Northwind Re Combined Net Gain from Operations U.S. Traditional Insurance Subsidiaries Tailwind Re and Northwind Re Statutory capital and surplus is as follows: (in millions of dollars) Combined Capital and Surplus U.S. Traditional Insurance Subsidiaries Tailwind Re and Northwind Re Year Ended December 31 2010 2009 2008 $628.8 $ 79.1 $639.2 $ 87.2 $540.8 $ 79.8 $645.7 $ 79.2 $741.2 $ 87.2 $682.0 $ 81.2 December 31 2010 2009 $3,395.1 $1,276.9 $3,286.9 $1,300.0 Restrictions under applicable state insurance laws limit the amount of dividends that can be paid to a parent company from its insurance subsidiaries in any 12-month period without prior approval by regulatory authorities. For life insurance companies domiciled in the United States, that limitation generally equals, depending on the state of domicile, either ten percent of an insurer’s statutory surplus 4356_2010AR_Fin_ALL.indd 153 153 4/4/11 3:05 PM Notes To Consolidated Financial Statements Unum 2010 with respect to policyholders as of the preceding year end or the statutory net gain from operations, excluding realized investment gains and losses, of the preceding year. The payment of dividends to a parent company from its insurance subsidiaries is generally further limited to the amount of unassigned statutory surplus. Based on the restrictions under current law, $622.3 million is available during 2011 for the payment of ordinary dividends to Unum Group from its traditional U.S. insurance subsidiaries, which exclude Tailwind Re and Northwind Re. The ability of Tailwind Re and Northwind Re to pay dividends to their respective parent companies, Tailwind Holdings and Northwind Holdings, wholly-owned subsidiaries of Unum Group, will depend on their satisfaction of applicable regulatory requirements and on the performance of the business reinsured by Tailwind Re and Northwind Re. We also have the ability to receive dividends from our United Kingdom insurance subsidiary, Unum Limited, subject to applicable insurance company regulations and capital guidance in the United Kingdom. Approximately £207.5 million is available for the payment of dividends from Unum Limited during 2011, subject to regulatory approval. Deposits At December 31, 2010 and 2009, our U.S. insurance subsidiaries had on deposit with U.S. regulatory authorities securities with a book value of $293.6 million and $292.1 million held for the protection of policyholders.

Our audits also included the financial statement schedules listed in the index at Item 15(a)(2). These financial statements and schedules are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedules based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Unum Group and subsidiaries at December 31, 2010 and 2009, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedules, when considered in relation to the basic financial statements taken as a whole, present fairly in all material respects the information set forth therein. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Unum Group and subsidiaries’ internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 25, 2011 expressed an unqualified opinion thereon. Chattanooga, Tennessee February 25, 2011 4356_2010AR_Fin_ALL.indd 155 155 4/4/11 3:05 PM Management’s Annual Report on Internal Control Over Financial Reporting Unum 2010 The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended. The Company’s internal control over financial reporting encompasses the processes and procedures management has established to (i) maintain records that, in reasonable detail, accurately and fairly reflect the Company’s transactions and dispositions of assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles; (iii) provide reasonable assurance that receipts and expenditures are appropriately authorized; and (iv) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, any projection of the evaluation of effectiveness to future periods is subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We assessed the effectiveness of our internal control over financial reporting, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and concluded that, as of December 31, 2010, we maintained effective internal control over financial reporting. 156 4356_2010AR_Fin_ALL.indd 156 4/4/11 3:05 PM Unum 2010 Annual Report Report of Independent Registered Public Accounting Firm The Board of Directors and Stockholders Unum Group We have audited Unum Group and subsidiaries’ internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Unum Group and subsidiaries’ management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying “Management’s Annual Report on Internal Control over Financial Reporting.” Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, Unum Group and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Unum Group and subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of income, stockholders’ equity, cash flows, and comprehensive income (loss) for each of the three years in the period ended December 31, 2010, and our report dated February 25, 2011 expressed an unqualified opinion thereon.
